[0025] DE 10 2004 058 598 A1 describes a device of a sheet-fed printing press for the finishing of printed and / or coated sheet-shaped substrates by means of a rotation process in which the substrate can be inserted in the feed direction between a rotating processing roller and a counterpressure processing roller.

[0029] When separating die-cut or pre-cut substrate sheets into waste parts and blanks, problems arise, particularly in low-humidity environments, caused by unwanted electrostatic charges on the waste parts and / or blanks and / or the surfaces of the tools or elevators. As a result of these electrostatic charges, waste parts and / or blanks adhere to the surfaces of the tools or elevators.

[0030] The invention is based on the object of creating a device for treating substrates, which enables the separation of processed substrates into one or more waste parts and at least one use.

[0031] This object is achieved by a device which is designed according to the features of patent claim 1.

[0032] The advantages achievable with the invention are that the separation of processed substrates, in particular punched sheets, into at least one waste part and at least one blank becomes more reliable.

[0033] In addition, contamination of the active tools, the elevator and other machine parts is counteracted because even the smallest material components such as fibers and dust are no longer attracted to the tools, the elevator and other machine parts.

[0036] The device for treating substrates 1 with a separating device 2, with which the processed substrate 1 can be separated into at least one waste part 9 and at least one blank 10, can be designed as an independent machine and in this case has a feed system for substrate 1, which is not described in more detail.

[0037] According to a further embodiment, the separating device 2 is a component of a substrate-processing machine, in particular a sheet-processing machine, and is operated inline with the units of the sheet-processing machine. A sheet-fed printing press, such as that used in Fig. 1. The invention is described below using the example of a sheet-fed printing press, in particular an offset sheet-fed printing press, whereby this description is also intended to apply analogously to other sheet-processing machines and to an embodiment of the device as a stand-alone machine.

[0038] The sheet-fed printing press comprises a feed system for substrates 1, also referred to as feeder 7. Substrates 1 are understood to be, in particular, sheet-shaped workpieces made of paper, cardboard, paperboard, corrugated cardboard, plastic, or the like, which are preferably printable or printed. The substrates 1 are present in the feeder 7 of the sheet-fed printing press as a stack, from which they are separated and fed to the units of the sheet-fed printing press downstream of the feeder 7 via an acceleration system 8. The sheet-fed printing press comprises at least one, preferably several, printing units 6. The printing units 6 each comprise, in particular, a printing cylinder 41 and a sheet guide cylinder 42, preferably designed as a transfer drum 42. Associated with the printing cylinder 41 is a blanket cylinder 43 carrying a rubber blanket, and associated with this cylinder is a plate cylinder 44 carrying a printing plate. The plate cylinder 44 is in contact with an inking unit 45 and preferably also with a dampening unit.In the printing unit 6, the substrate sheet 1 is guided in a conventional manner by the sheet holding systems provided on the printing cylinder 41 and sheet guide cylinder 42, printed in the printing nip formed between the printing cylinder 41 and the blanket cylinder 43, and transferred to the downstream unit of the sheet-fed printing press, e.g., in the form of the next printing unit 6. One or more processing units 46 can be provided downstream of the printing unit(s) 6 or between the printing units 6. The processing units 46 preferably comprise two processing cylinders 96, 97, one of which, preferably the lower one, has a sheet holding system, and the other, preferably the upper one, has a tool carrier. The sheet holding system of the processing cylinder 96 can be configured as a clamping gripper system or as a suction gripper system.In its function, it is preferably identical to the gripper system (clamp gripper system or suction gripper system) of the transport cylinder 3, to the description of which reference is made.

[0039] The processing cylinders are arranged in a cylinder gap. At least one of the processing cylinders carries a tool. In the simplest case, a processing cylinder pair is formed by the impression cylinder 41 and blanket cylinder 43 of a printing unit 6. In this case, one printing unit 6 serves as the processing unit 46. In this case, the tensioning device for the blanket serves to secure the tool to the blanket cylinder 43. The processing cylinders can be designed in a variety of ways.

[0040] According to an embodiment which is particularly suitable for punching and perforating applications, the upper processing cylinder is designed as a full magnetic cylinder or carrier cylinder with magnetic segments for receiving magnetic sheets or magnetic sheets and the lower processing cylinder is designed as a surface-hardened cylinder or with a hardened sheet fastened thereon.

[0041] According to another embodiment, which is particularly suitable for embossing or creasing or grooving applications, the upper processing cylinder is designed as a full magnetic cylinder or carrier cylinder with magnetic segments for receiving magnetic sheets or magnetic sheets and the lower processing cylinder is designed as a surface-hardened cylinder or with a hardened sheet attached thereto or with a sheet with hard rubber / plastic.

[0042] In all of the above cases, the lower machining cylinder can be equipped with mechanically locking tool carriers or lifting supports, particularly with positive or non-positive locking. The non-positive tool carriers or lifting supports are particularly designed with magnetic locking.

[0043] According to a further preferred embodiment, the device for treating substrates 1, which may be designed as a sheet-processing machine or may be a component thereof, in particular a processing unit 46, comprises a first and a second processing cylinder 96, 97. Substrate sheets 1 can be inserted between the first and a second processing cylinder 96, 97 and are processed as they pass through the cylinder gap between the processing cylinders 96, 97. The first processing cylinder 96 has a sheet holding system. The first and / or the second processing cylinder 96, 97 have a tool carrier for receiving a tool or a tool part, which preferably comes from the group of cutting tools, punching tools, creasing tools, perforating tools, or grooving tools.The second processing cylinder 97 is assigned a counter cylinder 98 on its side facing away from the first processing cylinder 96, which counter cylinder is in surface contact with the second processing cylinder 97.

[0044] The counter cylinder 98 is assigned to the processing cylinder 97 in such a way that when the processing cylinder 97 deflects, as occurs during processing of substrate sheet 1 in the gap between the two processing cylinders 96, 97, the force effect of the resulting bending force of the second processing cylinder 97 strikes the counter cylinder 98, preferably in its center or close to its center. From a geometric perspective, the centers of the first and second processing cylinders 96, 97 and the counter cylinder 98 preferably lie on an imaginary straight line, or the centers of the second processing cylinder 97 and the counter cylinder 98 lie on a straight line that is inclined by an angle of less than or equal to 10 degrees with respect to a straight line on which the centers of the first and second processing cylinders 96, 97 lie.

[0045] The counter cylinder 98 can have the same diameter as the second processing cylinder 97.

[0046] Likewise, the counter cylinder 98 and the second machining cylinder 97 can have bearer rings that are in rolling contact with each other. It is also possible for the surface contact between the counter cylinder 98 and the second machining cylinder 97 to be limited to the contact between the bearer rings. In this case, at least deflection of the second machining cylinder 97 is counteracted in the areas between its bearing points in a frame wall and the bearer ring adjacent to the respective bearing point.

[0047] The use of bearer rings is well known in printing press construction. Bearer rings on printing presses are mounted on the sides of the printing cylinders. The bearer ring is designed to prevent bearer rings. It is made of tempered steel and is ground to a high-precision, round, and dimensionally accurate finish. The bearer ring is approximately 1-4 cm wide and rolls either on the foundation rail or on the bearer ring of the counter cylinder. The circumference of the bearer ring is exactly the circumference of the packing or it has the exact circumference of the die, depending on which machine part it is attached to. The bearer ring is a positive guide element on centrally driven printing presses and compensates for minor bearing inaccuracies as well as uneven input and output from the gear drive of the printing press.

[0048] In the case of the formation of bearer rings, a device for adjusting the pressure between the bearer rings by displacing the counter cylinder 98 and / or the second processing cylinder 97 is advantageously provided.

[0049] The counter cylinder 98 is preferably assigned a device for securing a packing. This enables the arrangement of a packing on the counter cylinder 98 to ensure that the packing is in surface contact, in particular rolling contact, with the processing cylinder 97 or with the tool arranged on its surface, even when a tool, the thickness of which can vary, is arranged on the second processing cylinder 97. Preferably, the counter cylinder 98 is also assigned a device for tensioning the packing in the circumferential direction of the counter cylinder 98, which can form a structural unit with the device for securing a packing.

[0050] In particular for the use of a profiled dressing, for example in the form of a die, it proves to be advantageous if the counter cylinder 98 has a register system for positioning a dressing on the counter cylinder 98.

[0051] According to a further preferred embodiment, which facilitates the exchange of tool parts, the device for treating substrates 1 comprises a processing unit 46 with two interacting processing cylinders 96, 97, between which the substrate 1 can be inserted. The substrate 1 is processed as it passes through tool parts from the group of cutting tools, punching tools, creasing tools, perforating tools, or grooving tools, which are active in the cylinder gap between the processing cylinders 96, 97. At least one of the processing cylinders 96, 97 is designed as a magnetic cylinder. A peeling device for peeling off at least one tool part is assigned to the processing cylinder 96, 97 designed as a magnetic cylinder.

[0052] According to a further preferred embodiment, which facilitates the exchange of tool parts, the device for treating substrates 1 comprises a separating device with a transport cylinder 3 and a stripping cylinder 4, between which the substrate 1 can be inserted. As the substrate 1 passes through the cylinder gap between the transport cylinder 3 and the stripping cylinder 4, it is separated by at least one strip 5 into at least one waste part 9 and at least one blank 10. The transport cylinder 3 and / or the stripping cylinder 4 are designed as magnetic cylinders. A peeling device 103 for peeling off the at least one strip 5 is assigned to the transport cylinder 3 and / or the stripping cylinder 4. See in particular Fig. 47 and Fig. 48. The peeling device 103 is designed to be adjustable and / or detachable from the cylinder to which it is assigned and which is designed to support a packing 5, in particular from the processing cylinder 96, 97 or the transport cylinder 3 or the stripping cylinder 4. The peeling device 103 has a peeling edge 104. When the peeling device 103 is adjusted to the respective cylinder, the peeling edge 104 preferably extends tangentially or approximately tangentially to the periphery of the cylinder to which it is assigned, i.e. in particular to the processing cylinder 96, 97, transport cylinder 3 or stripping cylinder 4. Furthermore, it proves advantageous if the peeling device 103 forms a structural unit with a guard 70, 71. The protection 70, 71 can, for example, be any part of the housing of a machining unit 46 or a separating unit 2.2, which protects the operator from injuries caused by rotating cylinders or prevents or reduces noise or dust emissions. Assigning the peeling device 103 to parts of the plate changing unit or the device for changing the winding is also possible. If the peeling device 103 forms a structural unit with a guard 70, 71, the structural unit can function as the peeling device 103 in one position and as the guard 70, 71 in another position.

[0053] Preferably, the peeling device 103 has a holding element for securing the tool parts or the at least one winding device 5. The holding element can act pneumatically or magnetically or be designed in another suitable manner, e.g., in the form of a step or latch.

[0054] To ensure that the peeling device 103 engages under an edge of the tool part or of the at least one cover 5, the tool part or of the at least one cover 5 can be lifted manually. According to an advantageous alternative, an ejector is designed for this purpose, which is assigned to the processing cylinder 96, 97 and / or the transport cylinder 3 and / or the stripping cylinder 4 and which is designed to at least partially lift tool parts or the at least one cover 5 from the surface of the processing cylinder 96, 97 or the transport cylinder 3 or the stripping cylinder 4.

[0055] Preferably, a drive is provided which acts on the processing cylinder 96, 97 and / or the transport cylinder 3 and / or the stripping cylinder 4 and with which a drive control cooperates. The drive control causes the processing cylinder 96, 97 and / or the transport cylinder 3 and / or the stripping cylinder 4 to be automatically positioned in a position in which one end of a tool part or of the at least one cover 5 is opposite the peeling device 103 and / or is located within the effective range of the peeling device 103, in particular the peeling edge 104. After positioning, the drive control can cause the processing cylinder 96, 97 and / or the transport cylinder 3 and / or the stripping cylinder 4 to rotate such that the other end of the tool part or of the at least one cover 5 is opposite the peeling device 103 and / or is located within the effective range of the peeling device 103.During the rotation, the peeling device 103 peels the tool part or the at least one coating 5 from the respective cylinder surface. Between the positioning and rotation of the processing cylinder 96, 97 and / or the transport cylinder 3 and / or the stripping cylinder 4, the ejector is preferably activated to at least partially lift the respective tool part or the at least one coating 5 from the surface of the processing cylinder 96, 97 or the transport cylinder 3 or the stripping cylinder 4.

[0056] In the aforementioned context, a magnetic cylinder refers to all types of cylinders or drums that exert a magnetic force on adjacent ferromagnetic elements in the area of ​​their periphery, in particular on tools or tool parts from the group of cutting tools, punching tools, creasing tools, perforating tools, or grooving tools. Such a cylinder can be designed as a solid magnetic cylinder or a cylinder with embedded magnetic segments, or as a support cylinder for magnetic segments or magnetic sheets arranged on it, which applies analogously to the drum design.

[0061] The film feed 86 can have a storage 93 for receiving a stack formed from film sections and a separating device which separates film sections from the stack formed from film sections and accelerates them to the peripheral speed of the transport cylinder 3.1.

[0062] Preferably, the film feed 86 comprises a feed cylinder 84, which forms a press nip with the transport cylinder 3.1.

[0063] The separating device can have a transport element 94 for separating the film sections from the top or bottom of the stack formed from film sections. A transport element 94 is preferably designed to feed the film sections to the press nip formed between the feed cylinder 84 and the transport cylinder 3.1. The transport element 94 can have one or more elements from the group of suction belts and / or suction rollers and / or suction cups. The transport mechanism for the elements provided as transport elements 94 is preferably a force effect resulting from an applied negative pressure. Alternatively or in addition to this, a frictional connection can also serve as the transport mechanism. If a suction cup is provided as the transport element 94, this can be designed, for example, as a combined suction cup and have one or more drag suction cups that interact with one or more lifting suction cups.

[0064] The transport element 94 can be provided for the direct feeding of each individual film section to the press nip or feed cylinder 84. Direct feeding in this context means feeding without transfer, i.e., intermediate transfer to another transport element 94.

[0065] Openings are preferably formed in the outer surface of the feed cylinder 84, which can be supplied with suction air by air supply means. According to one embodiment, the air supply means can be configured to supply suction air depending on the angular position of the respective supplied openings.

[0067] If the coating device 88 is assigned to the transport cylinder 3.1, the substrate 1 is coated directly and then brought into contact with a film section. If the coating device 88 is assigned to the feed cylinder 84, the substrate 1 is coated indirectly. This means that the adhesion promoter, in particular the adhesive, is fed to a respective film section, which is then brought into contact with a substrate sheet 1.

[0068] The coating device 88 can be designed in the manner of a coating unit and / or comprise an applicator roller and / or an inkjet head. The coating device 88 is preferably designed such that it enables addressable, partial coating of the respective substrate sheet 1 or the respective film section with an adhesion promoter, in particular an adhesive. If a coating device 88 is designed with an applicator roller, a printing form, in particular a coating plate, in particular a flexographic plate, can be provided for the addressable, partial coating.

[0069] In a second preferred design of a window applicator 85 or film applicator 85, the film is in the form of a film web 87.

[0070] The second design preferably comprises a transport cylinder 3.1 for transporting sheet-shaped substrates 1, a sheet conveyor that interacts with the transport cylinder 3.1, and a film feed 86 that has means for guiding a film web 87. The second design is preferably associated with a coating device 88 for supplying an adhesion promoter to the substrate 1 and a cutting device 89 for cutting the film web 87 into film sections or for separating film sections from the film web 87. The film feed 86 preferably comprises means for guiding the film sections.

[0071] Preferably, the film feed 86 comprises a feed cylinder 84, which forms a press nip with the transport cylinder 3.1. The cutting device 89 can be associated with the feed cylinder 84.

[0073] The coating device 88 can be assigned to the transport cylinder 3.1 or a feed cylinder 84. If the coating device 88 is assigned to the transport cylinder 3.1, the substrate 1 is coated directly and then brought into contact with a film section. If the coating device 88 is assigned to the feed cylinder 84, the substrate 1 is coated indirectly. This means that the adhesion promoter, in particular the adhesive, is fed to a respective film section, which is then brought into contact with a substrate sheet 1.

[0074] The coating device 88 can be designed in the manner of a coating unit and / or comprise an applicator roller and / or an inkjet head.

[0106] For all described designs with a foil applicator or window applicator 85, it is advisable to arrange a turning device directly or indirectly upstream of the unit in which the adhesive is applied. This has the advantage that, for example, in the production of envelopes, the cutting or punching lines or material tears resulting from cutting or punching in the substrate 1 would appear on the inside of the envelopes, where they are less disruptive than on the outside.

[0107] In the following, a preferred method for treating sheet-shaped substrates 1 is described, which is carried out with one of the embodiments according to the Fig. 33 to 46 can be performed.

[0108] The method proceeds as follows. In a punching process step, window-shaped regions are punched out of the substrates 1, whereby material connections are retained. In a separating process step, which preferably follows directly after the punching process step, the window-shaped regions are broken out of the substrates 1, whereby the material connections are severed so that window-shaped recesses are formed in the substrates 1. In a coating process step, which preferably follows directly after the separating process step, the substrates 1 are coated with adhesive in the area adjacent to the window-shaped recesses. In a window application process step, film sections whose extent is greater than the extent of the window-shaped recesses are positioned over the window-shaped recesses and fixed with the adhesive.

[0109] Preferably, in the punching process step, blanks 10 are punched into the substrates 1, in each of which at least one window-shaped region is arranged, wherein further material connections between the blanks 10 and between the blanks 10 and the waste parts 9 are retained. In the case of a production of envelopes with windows, such a blank 10 would represent an unfolded envelope. After the window has been applied, the substrates 1 are either deposited directly on a stack or a conveyor belt 29, 30; alternatively, before depositing, the further material connections between the blanks 10 or between the blanks 10 and the waste parts 9, e.g. the outer frame, can be severed in a further separating process. It is also possible to print the substrates 1 before the punching process step.The described process steps are preferably carried out in successive units of a sheet-fed printing machine, in particular a rotary printing press.

[0110] A further embodiment relates to a method for treating sheet-shaped substrates 1.

[0111] The procedure is as follows.

[0112] A respective substrate sheet 1 is separated from a stack formed of substrate sheets 1 by a feeder 7, then embossed and / or dried in a first processing unit 46, then grooved or punched and / or pre-punched in a second processing unit 46, then punched and / or pre-punched and / or perforated and / or embossed and / or grooved in a third processing unit 46. Preferably, the respective substrate sheet 1 is printed in one or more printing units 6 and / or varnished in one or more varnishing units between the separation in the feeder 7 and the processing in the first processing unit 46. Alternatively or additionally, the printing and / or varnishing in at least one printing or varnishing unit can also take place between the processing in two of the processing units 46 and / or after the processing in the last processing unit 46.After separation, the sheet-shaped substrates 1 or blanks 10 are preferably deposited in a delivery 99 or on a conveyor belt 29, 30 on a stack or as a sequence, shingled or unshingled.

[0113] Cutting refers, in particular, to the complete mechanical separation of an unpunched material through pressure, with shear stresses acting predominantly. The cutting process can be performed using the knife cut, shear cut, or burst cut principle.

[0114] Punching is defined, in particular, as the division of materials along a non-straight line. This primarily involves the production of cutouts and blanks with closed boundary lines. In some cases, however, open cuts are also realized by punching, e.g., rounding corners and register punching.

[0115] Embossing is the processing of materials by pressure with appropriate tools, whereby the material is shaped and / or deformed in a relief-like manner.

[0116] Grooving is the processing of materials by applying pressure with appropriate tools, whereby elongated, narrow depressions are created in the surface of the material.

[0117] Perforation is the processing of materials by applying pressure with appropriate tools, whereby a large number of holes, usually arranged in a line, are created in the material. The distances between the holes are preferably equal.

[0118] To carry out the individual process steps of the described methods, a separate plant is preferably provided, which can be combined with other plants in any sequence to implement modified production processes. For this purpose, the plants preferably have separate frame walls. In particular, the punching process step or the punching and separating process steps are carried out with a punching plant, the separating process step with a separating plant 2.2, the coating process step with a coating plant 88.2, the window application process step or the coating and window application process steps with a window application plant 85. Each of the aforementioned plants, with the exception of the last plant, transfers the substrate 1 to the subsequent plant after carrying out at least one process step.

[0119] Depending on the particular machine configuration implemented, with or without a foil applicator or window applicator 85, after passing through various processing stages, either substrate sheets 1 (sheets 10 connected to one another via residual webs, with or without frames) are produced, which are stacked in a delivery 99, or punched sheets 10, which are preferably conveyed out of the machine on a conveyor belt 30. These sheets 10 are preferably divided into sheet streams that are laterally spaced from one another. For this purpose, several pairs of rollers are arranged downstream of the conveyor belt 30, with each pair of rollers being arranged at a different lateral angle to the other pairs. The pairs of rollers each form a roller gap and rotate at a peripheral speed that is greater than the speed of the conveyor belt 30.The blanks 10 lying side by side and one behind the other are conveyed by the conveyor belt 30 into a respective roller nip. In the roller nip, the respective blanks 10 are then grasped, accelerated to the peripheral speed of the rollers, and spaced apart from one another according to the orientation of the roller pair. The roller pairs can be moved transversely to their transport direction 74 for positioning on the blanks 10. A conveyor belt is arranged downstream of the roller pairs, which picks up the blanks 10, now laterally spaced apart, and transports them away. The downstream conveyor belt preferably runs at a speed that is lower than the peripheral speed of the roller pairs.

[0120] A device for treating, in particular depositing, substrates 1, in particular blanks 10, can be connected to the downstream conveyor belt, which is subsequently used in particular with regard to the Fig. 18 and Fig. 19. The device comprises a circulating conveyor belt 29, 30 which conveys the substrates 1, in particular blanks 10, in at least one path, preferably as an imbricated stream, against at least one stop 77 for depositing the substrates 1 on a stack carrier 78. The stack carrier 78 can be a commercially available pallet or a system pallet such as those used in logistics systems of printing companies or in the field of further processing. For handling, in particular relocating, the stack carrier 78, a transport device 79 is designed, with which the stack carrier 78 can be displaced under the at least one stop 77 and / or the conveyor belt 29, 30 in such a way that the substrate sheets 1 or blanks 10 conveyed by the conveyor belt 29, 30 are deposited on the stack carrier 78. The transport device 79 is designed for vertical and horizontal displacement of the stack carrier 78.The conveyor belt 29, 30 is assigned a device for forming a gap in the shingled stream 83, which is preferably designed as a roller 83 or roller. The roller 83 or roller is arranged so as to be displaceable, for which purpose it is preferably mounted on levers at the ends. If a gap is to be formed in the shingled stream, for example because the stack carrier 78 has to be moved or replaced, the roller 83 or roller is displaced or pivoted until it is in surface contact with the conveyor belt 29, 30. If the conveyor belt 29, 30 conveys further substrate sheets 1 as a result of its movement, these are accumulated on the roller 83 or roller. The roller 83 or roller can be fixed or rotatable and is preferably braked in the latter case.

[0121] The transport device 79 is designed to move the stack carrier 78 into one or more positions in which the stack carrier 78 and the at least one stop 77 and / or the stack carrier 78 and the conveyor belt 29, 30 overlap. Preferably, a plurality of stops 77 are arranged next to one another in groups transversely to the transport direction 74 of the substrate sheets 1 or the blanks 10 on the conveyor belt 29, 30. More preferably, each group of stops 77 has either two side stops or two side stops and a rear stop. In each case, a group of stops preferably forms a type of pocket, which is aligned by lateral positioning of the stops 77 on the stream(s) of substrate sheets 1 or blanks 10 on the conveyor belt 29, 30.

[0122] The stops 77 are designed to be vertically movable. One or more drives are designed for the synchronous displacement of the stops 77. The transport device 79 preferably has a drive designed for the discontinuous or continuous displacement of the stack carrier 78. The transport device 79 is preferably designed to displace the stack carrier 78 in and against the transport direction 74 of the conveyor belt 29, 30. More preferably, the transport device 79 is designed to displace the stack carrier 78 in the transport direction 74 of the conveyor belt 29, 30 depending on the extension of the substrates 1 or blanks 10 in the transport direction 74 of the conveyor belt 29, 30.Further preferably, the transport device 79 is designed to realize a movement cycle which comprises a first and at least one further movement of the stack carrier 78 in the transport direction 74 of the conveyor belt 29, 30, wherein the stack carrier 78 is stationary between its first and its at least one further movement with respect to the transport direction 74 of the conveyor belt 29, 30.

[0123] Furthermore, a feed device 80 can be configured, with which at least one separating element 81 can be positioned on the substrates 1 carried by the stack carrier 78. The feed device 80 comprises a separating device that separates the separating elements 81 from a stack 82 formed from a plurality of separating elements 81. The separating elements 81 are preferably sheet-shaped materials that can be inserted between stacks of blanks to spatially separate them from one another. The feed device 80 can be formed by a horizontally displaceable frame, the underside of which is assigned vertically displaceable suction cups or other suitable fixing elements. The design of the feed device 80 with rigid suction cups or other suitable fixing elements is also possible, provided the frame permits a vertical movement for lifting a respective separating element 81.

[0124] Preferred movement sequences, which the stack carrier 78 realizes by the action of the transport direction 74, are to be described below, particularly with regard to the Fig. 20 to 32 are described as examples.

[0125] First, the stack carrier 78 is positioned by the transport device 79 with respect to the conveyor belt 29, 30 in such a way that, with respect to its vertical position, it has the smallest possible distance from the underside thereof. With respect to its horizontal position, the positioning takes place in such a way that blanks 10 or substrate sheets 1 conveyed by the conveyor belt 29, 30 are deposited on the stack carrier 78. With the conveyor belt 29, 30 rotating, the substrate sheets 1 or blanks 10 are then conveyed onto the stack carrier 78 and are aligned laterally and preferably also in the transport direction 74 by the stops 77. As the stack continues, the substrate sheets 1 or blanks 10 grow, as shown in Fig. 21. The stack carrier 78 is preferably lowered. The stops 77 can be lowered synchronously with the lowering movement of the stack carrier 78. Alternatively, the stack carrier 78 can be positioned from the outset at such a vertical distance from the conveyor belt 29, 30 that it can accommodate a sufficient quantity of substrate sheet 1 or blank 10 without vertical movement. Fig. 21, only one stack is visible. In addition to this, several further adjacent stacks can be formed simultaneously. When the stack of substrate sheets 1 or blanks 10 has reached a sufficient height, the stops 77, if they were moved with the stack carrier 78, are moved vertically back to their starting position. The stack carrier 78 is moved vertically to its starting position and horizontally by a distance that corresponds to the length of the substrate sheets 1 to be deposited plus a distance value. The temporal sequence of the movement of the stack carrier 78 and stops 77 is unimportant as long as collisions are avoided. The movement preferably takes place synchronously. During the movement of the stack carrier 78, the device for forming a gap in the shingled stream 83 is activated, so that no substrate sheets 1 or blanks 10 are fed to the stack carrier 78 during this time.After deactivating the device for forming a gap in the shingled stream 83, the next stack of substrate sheets 1 or blanks 10 can be formed on the stack carrier 78 (. Fig. 24).

[0126] The processes are then repeated, as described for the formation of the first stack of substrate sheet 1 or blank 10, once or several times until another stack or further stacks of the desired height are formed, which, viewed in the transport direction 74, lie one behind the other and, if necessary, also next to each other ( Fig. 25).

[0127] At this point in the process, the feed device 80 can be used. This picks up the uppermost separating element 81 of the stack 82 formed from separating elements 81 and transports it over the stacks of substrate sheets 1 or blanks 10 formed on the stack carrier 78, where it is released and placed on the respective uppermost substrate sheet 1 or blank 10 ( Fig. 26). The surface of the separating sheet 81 subsequently replaces the surface of the stack support 78 and thus forms the new stacking level.

[0128] In a next step, a single or a series of stacks of substrate sheets 1 or blanks 10 are formed on the new stacking level. For this purpose, the stack carrier 78 is positioned with respect to its vertical position by the transport device 79 such that the new stacking level lies below the release level of the conveyor belt 29, 30. With respect to its horizontal position, the positioning is such that blanks 10 or substrate sheets 1 conveyed by the conveyor belt 29, 30 are deposited on the separating element 81. ( Fig. 28) With the conveyor belt 29, 30 rotating, substrate sheets 1 or blanks 10 are then conveyed onto the separating element 81 and are aligned laterally and preferably also in the transport direction 74 by the stops 77. The stack of substrate sheets 1 or blanks 10 grows further as shown in Fig. 29 shown.

[0129] The stack carrier 78 is preferably lowered. The stops 77 can be lowered synchronously with the lowering movement of the stack carrier 78. Alternatively, the stack carrier 78 can also be positioned from the outset at such a vertical distance from the conveyor belt 29, 30 that it can accommodate a sufficient quantity of substrate sheets 1 or blanks 10 without vertical movement. When the stack of substrate sheets 1 or blanks 10 has reached a sufficient height, the stops 77, if they were moved with the stack carrier 78, are moved vertically back to their starting position. The stack carrier 78 is moved vertically into the position it occupied at the beginning of the formation of the first stack on the separating element 81 and horizontally by a distance corresponding to the length of the substrate sheets 1 to be deposited plus a distance value.

[0130] During the displacement of the stack carrier 78, the device for forming a gap in the shingled stream 83 is activated, so that during this time no substrate sheets 1 or blanks 10 are fed to the stack carrier 78. After deactivating the device for forming a gap in the shingled stream 83, the next stack of substrate sheets 1 or blanks 10 can be formed on the separating element 81 ( Fig. 31). If a sufficient number of stacks of substrate sheets 1 or blanks 10 have been formed on the stack carrier 78, the loaded stack carrier 78 is removed and replaced by a new, capable stack carrier 78.

[0131] The sequence of units of the sheet-fed printing press results from the technological requirements. Preferably, one or more processing units 46 are arranged downstream of one or more printing units 6. In the case of multiple printing units 6, these are usually equipped with different tools from the group of cutting tools, punching tools, creasing tools, perforating tools, or grooving tools. Likewise, one or more processing units 46 can be arranged upstream of one or more printing units 6. Alternatively, one or more processing units 46 can be arranged between one or more printing units 6. Preferably, the sheet-fed printing press also comprises one or more coating units, which are preferably arranged downstream of the printing units 6 or adjoin the processing units 46.

[0132] A substrate processing machine, in particular a sheet processing machine, which is not a printing machine, can be similar in structure to the sheet-fed printing machine described, minus the printing units 6.

[0133] The separating device 2 is formed downstream of the printing units 6 or the processing units 46. The separating device comprises a transport cylinder 3. The transport cylinder 3 is double-sized, i.e. it transports two substrate sheets 1 per revolution. However, the invention is not limited to a double-sized embodiment of the transport cylinder 3. The invention is described below using a single-sized system. This description also represents the double-sized system or multiple-sized system in an analogous manner. In the region of the outer surface of the transport cylinder 3, a sheet holding system for fixing the leading edges of sheet-shaped substrate 1, in particular a gripper system, is formed (in the case of a double-sized system, two sheet holding systems are formed). The gripper system is preferably designed as a suction gripper system 17, also referred to as a suction system 17, and is supplied by air supply means.The suction gripper system 17 is designed to create a suction area whose extension in the axial direction of the transport cylinder 3 is a multiple of its extension in the circumferential direction. The extension of the suction area of ​​the suction gripper system 17 in the circumferential direction of the transport cylinder 3 is preferably less than 20 mm, more preferably less than 15 mm, more preferably less than 10 mm. The suction area can be formed by a continuous opening extending across the width of the transport cylinder 3 or by a plurality of adjacent suction openings. The at least one suction opening is arranged to fix the front edge of the substrate 1 such that, when the lift 5 is fixed, it is spaced from the lift 5 in the circumferential direction of the transport cylinder 3. Advantageously, the extension of the suction area in the axial direction of the transport cylinder 3 is adjustable.For this purpose, adjustment means 28, particularly in the form of shut-off valves, can be provided in the suction air supply path for the outer suction openings with respect to the center of the transport cylinder 3. The adjustability of the extension of the suction area has the advantage that suction air consumption is minimized. The transport cylinder 3 further preferably has means (in the case of a double-sized system, two fixing means are provided) for fixing an interchangeable packing 5. The fixing means are preferably designed as clamping grippers. With them, a respective packing 5 can be fixed at the rear edge and at the front edge. The means for fixing the front edge of the packing 5 are preferably formed by the front edge clamping element 22 (also referred to as a clamping jaw) and the further clamping element 24 (also referred to as an impact element) which interacts correlatively with the latter to form a clamping gap.The further clamping element 24 is fixedly mounted on the base body of the transport cylinder 3. The clamping element 22 is fixedly connected to a lever 21, which is mounted on the base body of the transport cylinder 3 so as to be pivotable about a pivot point 34. The lever 21 is tensioned by an energy accumulator 23, preferably designed as a spring, such that the clamping gap formed between the clamping element 22 and the further clamping element 24 closes. The spring 23 is designed as a compression spring and is supported with one end on the lever 21 and with its other end on the head of a screw screwed into the base body of the transport cylinder 3. The . Fig. 3 shows the clamping gripper front edge with the front edge of the elevator 5 fixed, ie in the closed state. Fig. 4 shows the front edge clamping gripper with the front edge of the packing 5 released, i.e. in the open state. The opening of the front edge clamping gripper is effected counter to the force of the spring 23. The force required to open the front edge clamping gripper is preferably applied by an actuating element 23, which can in particular be designed as a pneumatic muscle 23. The actuating element, or the pneumatic muscle 23, preferably acts on a further lever 33, one end of which is supported on a fixed point of the transport cylinder 3. Under the force of the actuating element 23, which can in particular be designed as a pneumatic muscle 23, the further lever 33 can be pivoted about the aforementioned fixed point. In the case of the design as a pneumatic muscle 23, this is pressurized with compressed air, under the effect of which it expands, whereby the further lever 33 is pivoted.The pivoting movement of the further lever 33 is limited by a wall formed on the transport cylinder 3. The further lever 33 acts on a ball 35 which is formed between the further lever 33 and the lever 21 and displaces the latter. As the ball 35 is displaced, the lever 21 and with it the clamping element front edge 22 are also displaced. If the actuating element 23 is actuated in the opposite direction or the pneumatic muscle 23 is depressurized, i.e. switched to a powerless state, the force of the energy accumulator 23, in particular the spring 23, displaces the lever 21, the ball 35 and the further lever 33 back towards their initial position until the movement is limited by the clamping element front edge 22 striking the further clamping element front edge 24 or the elevator 5.The rear edge of the packing 5 can be secured between a rear edge clamping element 47 and another rear edge clamping element 48, which together form a further clamping gap. The force required to close the rear edge clamping gripper is applied by a rotatable tensioning shaft 50, which acts on the rear edge clamping element 47 via a toggle lever 51. To tension the packing 5, at least one of the clamping grippers—the front edge clamping gripper or the rear edge clamping gripper—can be displaced in the circumferential direction of the transport cylinder. Fig. 3 and Fig. 4, the rear edge clamping gripper is displaceable. In particular, the rear edge clamping gripper is mounted on a carriage that can be moved in the circumferential direction of the transport cylinder 3. The carriage 49 preferably carries, in addition to the rear edge clamping gripper, also the tensioning shaft 50 and the toggle lever 51. To tension the packing 5, it is first fixed at its two ends by the front edge clamping gripper and the rear edge clamping gripper. The carriage 49 is then moved clockwise, which is effected by a further actuating element 52, which can also be designed as a pneumatic muscle. Regardless of the type of design of the means for fixing the packing 5, these preferably carry positioning pins or are preferably assigned positioning elements. The positioning pins or positioning elements can, in particular, be directly assigned to the further front edge clamping element 22.

[0134] The transport cylinder 3 preferably has first and second openings 12, 13 which, when the elevator 5 is fixed, are at least partially covered by the openings that can be formed in the elevator 5. The openings 12, 13 are connected to air supply means 14, 15. In particular, first air supply means 14 is provided for supplying the first openings 12 with air and second air supply means 15 is provided for supplying the second openings 13 with air. In the following context, air is understood to mean all forms of system air, ie in particular blown air or suction air, which are suitable in particular for exerting a physical effect such as e.g. force and which can be characterized by at least one of the parameters static pressure, dynamic pressure or volume flow. In particular, the chemical composition of the air or its moisture content is not important here.Such air is generated in a conventional manner using compressors, condensers, vacuum pumps, suction pumps, or similar components. The aforementioned air generators can be comprised of the first and second air supply means 14, 15, including the transport cylinder, and in particular, together with all means that supply the air to the openings 12, 13 and / or control the supply, forming the air supply means 14, 15.

[0135] The first and second openings 12, 13 can preferably be supplied with air independently of one another. Preferably, the air supply to either the first or the second openings 12, 13, or both openings 12, 13, is designed to be switchable. In this sense, switchability refers in particular to switching between suction air and blown air, whereby the type of air supply is not important.

[0136] The first and second openings 12, 13 are formed in the outer surface of the transport cylinder 3. The first and second openings 12, 13 are preferably arranged alternately in the circumferential direction of the transport cylinder 3 or in the axial direction of the transport cylinder 3. The first and / or second openings 12, 13 are preferably groove-shaped or hole-shaped. The arrangement of the first and second openings 12, 13 in the outer surface of the transport cylinder 3 preferably results in a fine-meshed network of elements with which any openings formed in the packing 5 can be supplied with air. The arrangement of the openings in the packing 5 corresponds to the arrangement of the waste part or parts 9 on the one hand and the blank 10 on the other.For example, in the area of ​​those first openings 12 that are formed in the area of ​​blanks, perforations can be formed in the packing 5, while all second openings 13 that are formed in the area of ​​blanks 10 are not opposite any perforations in the packing 5. The same applies analogously to the area of ​​waste parts 9, whereby here the second openings 13 are opposite perforations in the packing 5, while the first openings 12 are covered by closed areas of the packing 5. Through these measures, blanks 10 and waste parts 9 can be treated differently or fixed on the outer surface of the transport cylinder 3 or its packing 5.

[0137] The details of the air supply to the first and second openings 12, 13 are shown in particular in the Fig. 5, Fig. 6 and Fig. 7. The air supply means 14, 15 for supplying the first and second openings 12, 13 preferably comprise one or more rotary valves or rotary inlets. Preferably, the rotary valves or rotary inlets are formed on the end face of the transport cylinder 3 or associated therewith. Preferably, two rotary valves or two rotary inlets are formed on opposite end faces of the transport cylinder 3. In the Fig. 5, Fig. 6 and Fig. In the example shown in Figure 7, the rotary valve or the at least one rotary inlet comprises a disk 18, which is assigned to one of the end faces of the transport cylinder 3. A plurality of groove-shaped recesses 19, 56, 57 are formed in the disk 18, which preferably extend in the shape of a circular segment, coaxial with the rotational axis 16 of the transport cylinder 3. The recess 19 is supplied with air via a first supply nozzle 53, the recess 56 via a second supply nozzle 54, and the recess 57 via a third supply nozzle 55. The recesses 19, 56, and 57 are formed on the side of the disk 18 facing the transport cylinder 3. They extend in the shape of a circular segment at different radii, coaxial with the rotational axis 16 of the transport cylinder 3.Each of the recesses 19, 56 and 57 does not have to be continuous in the circumferential direction of the disc 18 but can rather be perforated, so that several recesses 19, 56 and 57 are formed one behind the other in the circumferential direction of the disc 18. The recesses 19, 56 and 57 correspond in terms of their distance (radius) to the axis of rotation 16 of the transport cylinder 3 with openings 58 formed in the front side of the transport cylinder 3. Each of the openings 58 in the front side of the transport cylinder 3 communicates via further lines either with a single one or a part of the first openings 12 or with a single one or a part of the second openings 13 in the outer surface of the transport cylinder 3 or with the suction gripper system 17. This of course only applies as long as the respective opening is opposite the respective recess 19, 56 and 57 depending on the angular position of the transport cylinder 3. In the one in . Fig. In the embodiment shown in Figure 2, the recesses 57 closest to the rotational axis 16 of the transport cylinder 3 supply the suction gripper system 17, the recesses 56 adjacent to these supply the second openings 13, and the recesses 19 adjacent to these supply the first openings 12.

[0138] The disc 18 is stationary relative to the transport cylinder 3, which rotates about the rotational axis 16 during operation. The extension of the recesses 19, 56, and 57 in the circumferential direction of the transport cylinder 3 determines the areas of suction or blowing air that are formed on the outer surface of the transport cylinder 3 in relation to the angle of rotation.

[0139] In addition to these effects, the areas of suction or blowing air can also be determined by the type of air supply or its activation or deactivation. Thus, the area supplied by the same air supply means 12 or 13 corresponding to the recesses 19, 56 can be shortened by switching off the air supply at an angle. Likewise, an area supplied by the same air supply means 12 or 13 corresponding to the recesses 19, 56 can be divided into at least one suction area and at least one blowing area by switching the air supply between a suction air supply and a blowing air supply. The suction area on the outer surface of the transport cylinder 3 is used for fixing, and the blowing area is used for ejecting blanks 10 or waste parts 9.It goes without saying that the air supply for the first openings 12 is preferably independent of the air supply for the second openings 13.

[0140] According to a preferred embodiment, the first and / or second air supply means 14, 15 are designed to switch off the suction air supply or to switch between suction air supply and blown air supply depending on the angular position of the respectively supplied openings 12, 13. Preferably, the first air supply means 14 switches the air supply to the first openings 12 off or switches from suction air supply to blown air supply when the respective first openings 12 reach a first release point due to rotation of the transport cylinder 3 about its axis of rotation 16. More preferably, the second air supply means 15 switches the air supply to the second openings 13 off or switches from suction air supply to blown air supply when the respective second openings 13 reach a second release point due to rotation of the transport cylinder 3 about its axis of rotation 16.

[0141] The disc 18 is preferably connected to a frame via a torque support 20 and is rotatably mounted on the transport cylinder 3. The transport cylinder 3 is preferably rotatably mounted in the same frame to which the torque support 20 is hinged.

[0142] In order to shift the areas of suction or blowing air, which are formed on the outer surface of the transport cylinder 3 in relation to the angle of rotation, actuators for rotating the disc 18 can be provided.

[0143] To facilitate assembly, the disc 18 preferably has a recess which allows radial displacement of the disc 18 in the sense of a shift for the purpose of replacement.

[0144] Instead of one disc 18, several discs 18 can also be provided. In the case of several discs 18, the recesses 57 for supplying the suction gripper system 17 are formed in one of the discs 18, and the recesses 19 and 56 for supplying the first and second openings 12, 13 are formed in the other disc 18.

[0145] The details of the supply of the suction gripper system 17 are shown in a preferred variant in Fig. 8. In the illustrated embodiment, the disc 18 serves to supply the first and second openings 12, 13 as well as the suction gripper system 17.

[0146] Alternatively, the disc 18 can also exclusively have a groove-shaped recess 57, which preferably extends in the shape of a circular segment, coaxial with the rotational axis 16 of the transport cylinder 3. In this embodiment, the recess 57 is also supplied with air from a third supply nozzle 55. The recess 57 is formed on the side of the disc 18 facing the transport cylinder 3. The recess 57 is preferably continuous or interrupted in the circumferential direction of the disc 18, so that several recesses 57 or sections of the recess 57 are formed on the same radius, viewed in the circumferential direction of the disc 18. The recess 57 corresponds, in terms of its distance (radius) from the rotational axis 16 of the transport cylinder 3, to one or more openings 58 formed in the end face of the transport cylinder 3. The or each opening 58 communicates with the suction gripper system 17 via further lines.This, of course, only applies as long as the respective opening 58 is opposite the recess 57, depending on the angular position of the transport cylinder 3. In other words, the length and position of the angular range in which suction air is applied to the suction gripper system 17, i.e., the suction gripper system 17 exerts a holding effect, is determined by the extent and position of the recesses 57.

[0147] It goes without saying that the air supply to the suction gripper system 17 is not limited to the described embodiment with discs 18. The air supply to the suction gripper system 17 can also be implemented with other known embodiments of an air supply that can cyclically activate and deactivate the suction air applied to the suction gripper system 17 with sufficient speed.

[0148] The suction gripper system 17 is formed in the region of the outer surface of the transport cylinder 3. The suction gripper system 17 is preferably assigned to the means for securing the elevator 5. In particular, the suction gripper system 17 can be mounted on the means for securing the elevator 5. Preferably, the means for securing the elevator 5, and thus also the suction gripper system 17, are mounted movable, in particular pivotably. The suction gripper system 17 can, in particular, be assigned to the clamping element front edge 22. It is also advantageous to arrange the suction gripper system 17 together with the clamping element 22 on the lever 21.

[0149] According to a preferred embodiment, a stripping cylinder 4 is arranged adjacent to the transport cylinder 3. The stripping cylinder 4 is rotatably mounted like the transport cylinder 3. The stripping cylinder 4 serves to strip waste parts 9 or blanks 10. Preferably, the stripping cylinder 4 has third openings 32. Third air supply means are provided to supply the third openings 32 with air.

[0150] The stripping cylinder 4, like the transport cylinder 3, can also be designed to be double-sized or single-sized. In the case of a double-sized stripping cylinder 4, its circumference or diameter corresponds to the circumference or diameter of a double-sized transport cylinder 3. Preferably, the stripping cylinder 4 is designed to be single-sized. In its construction, the stripping cylinder 4 is preferably similar to the transport cylinder 3 in many features, so that for a description of the nature of the stripping cylinder 4, reference is made to the explanations regarding the nature of the transport cylinder 3. This applies in particular to all assemblies of the transport cylinder 3 or the stripping cylinder 4 for which no explicit reference is made to structural differences or a lack thereof. The nature of the stripping cylinder 4 is described below using a single-sized system.This description also represents the double-size or multi-size system in analogous fashion. Unlike the transport cylinder 3, the stripping cylinder 4 does not include a sheet holding system for securing the leading edges of sheet-shaped substrate 1.

[0151] Like the transport cylinder 3, the stripping cylinder 4 preferably has means for securing an exchangeable packing 5. The securing means are preferably designed as clamping grippers. With them, a respective packing 5 can be secured at the rear edge and at the front edge. The means for securing the front edge of the packing 5 are preferably formed by the front edge clamping element 22 and the further clamping element 24, which interacts correlatively with it to form a clamping gap. The front edge clamping element 22 is mounted on the base body of the stripping cylinder 4. The further clamping element 24 can in particular be formed as a leaf spring assembly. Adjacent to the further clamping element 24 is an actuating element 25, preferably designed as a pneumatic muscle. The actuating element is preferably connected to an air supply, with which an overpressure can be applied to the actuating element 25.When overpressure is applied, the actuating element 25 expands, resting against the further clamping element 24 and deforming it. As a result of the deformation, in particular the bending of the further clamping element 24, its extension changes in the direction of the clamping element front edge 22. By applying overpressure, e.g. in the form of compressed air, to the actuating element 25, the gap formed between the clamping element front edge 22 and the further clamping element 24 can be enlarged. When the overpressure at the actuating element 25 is switched off, the gap can be reduced, which corresponds to the clamping of the elevator 5. The . Fig. 10 shows the clamping gripper of the stripping cylinder 4 front edge with fixed front edge of the elevator 5, ie in the closed state.

[0152] The rear edge of the elevator 5 can be secured between a rear edge clamping element 47 and another rear edge clamping element 48, which together form a further clamping gap. The force required to close the rear edge clamping gripper is applied by a rotatable tensioning shaft 50, which acts on the rear edge clamping element 47 via a toggle lever 51.

[0153] To tension the elevator 5, at least one of the clamping grippers, i.e. the clamping gripper front edge or the clamping gripper rear edge, can be displaced in the circumferential direction of the stripping cylinder 4. In the Fig. 10, the rear edge clamping gripper is displaceable. In particular, the rear edge clamping gripper is mounted on a carriage 49 that can be displaced in the circumferential direction of the stripping cylinder 4. The carriage 49 preferably carries, in addition to the rear edge clamping gripper, the tensioning shaft 50 and the toggle lever 51. To tension the packing 5, it is first fixed at both ends by the front edge clamping gripper and the rear edge clamping gripper. The carriage 49 is then displaced counterclockwise, which is effected by a further actuating element 52, which can also be designed as a pneumatic muscle.

[0154] Regardless of the design of the means for securing the cover 5, these preferably carry positioning pins or are preferably associated with positioning elements. The positioning pins or positioning elements can, in particular, be directly associated with the further clamping element, front edge 22.

[0155] It goes without saying that the described elements for securing the leading edge and the elements for securing the trailing edge can also be designed in other ways. As an alternative to the design of force-locking elements, it also proves advantageous if the elements for securing the leading edge and / or the elements for securing the trailing edge are designed for positively securing the elevators 5. In this case, hook-shaped or claw-shaped retaining elements can be designed, in particular, which correspond to recesses formed in the elevator 5 or engage in retaining rails that are firmly connected to the elevator 5.

[0156] The clamping gripper front edge or the clamping gripper rear edge are preferably mounted in a channel of the stripping cylinder 4, which can be spanned by a channel cover.

[0157] The stripping cylinder 4 preferably has third openings 32 which, when the elevator 5 is fixed, are at least partially covered by the openings that can be formed in the elevator 5. The third openings 32 are connected to third air supply means. In the following context, air is understood to mean all forms of system air, ie in particular blown air or suction air, which are suitable in particular for exerting a physical effect such as a force effect and which can be characterized by at least one of the parameters static pressure, dynamic pressure or volume flow. Such air is generated in a manner known per se using compressors, condensers, vacuum pumps, suction pumps or similar components.

[0158] The third openings 32 can be supplied with suction air. Preferably, the air supply is designed to be switchable. In this sense, switchability refers in particular to switching between suction air and blowing air, whereby the type of air supply being switched from one to the other is irrelevant.

[0159] The third openings 32 are formed in the outer surface of the stripping cylinder 4. The third openings 32 are preferably groove-shaped or hole-shaped. The arrangement of the third openings 32 in the outer surface of the stripping cylinder 4 preferably results in a fine-meshed network of elements with which any openings formed in the packing 5 can be supplied with air. The arrangement of the openings in the packing 5 corresponds to the arrangement of the waste part or parts 9 on the one hand or the blanks 10 on the other. For example, openings in the packing 5 can be formed in the area of ​​those third openings 32 that are formed in the area of ​​the blanks. This proves advantageous if the stripping cylinder 4 is to be used to transport the blanks 10.

[0160] If the stripping cylinder 4 is intended to be used to transport waste parts 9, openings are preferably formed in the packing 5 in the area of ​​those third openings 32 that are formed in the area of ​​the waste parts 9. These measures allow the blanks 10 or waste parts 9 to be treated differently or fixed to the outer surface of the transport cylinder 3 or its packing 5. The release of the blanks 10 or waste parts 9 can be assisted by applying blast air to the third openings 32.

[0161] The details of the air supply to the third openings 32 are not shown separately and are described below with reference to the design of the air supply means 14, 15 on the transport cylinder 3. The air supply means for supplying the third openings 32 preferably comprise a rotary valve or a rotary inlet. Preferably, the rotary valve or the rotary inlet is formed on the end face of the stripping cylinder 4 or is assigned thereto. The rotary valve or the at least one rotary inlet preferably comprises a disk 18 assigned to one of the end faces of the stripping cylinder 4. A recess is formed in the disk 18, which preferably extends in the shape of a circular segment, coaxial with the axis of rotation of the stripping cylinder 4. The recess is supplied with air via a fourth supply nozzle 53. The recess is formed on the side of the disk 18 facing the stripping cylinder 4.The recess is not continuous in the circumferential direction of the disc 18 but can rather be perforated, so that several recesses are formed one behind the other in the circumferential direction of the disc 18. Each recess corresponds, with regard to its distance (radius) from the axis of rotation of the stripping cylinder 4, to openings 58 formed in the front side of the stripping cylinder 4. Each of the openings 58 in the front side of the stripping cylinder 4 communicates via further lines either with a single opening or with some or all of the third openings 32 in the outer surface of the stripping cylinder 4. This, of course, only applies as long as the respective opening 58 is opposite the respective recess, depending on the angular position of the stripping cylinder 4.

[0162] The disc 18 is stationary relative to the stripping cylinder 4, which rotates around its central axis during operation. The extent of the recesses in the circumferential direction of the stripping cylinder 4 determines the areas of suction or blowing air that are formed on the outer surface of the stripping cylinder 4 in relation to the angle of rotation.

[0163] In addition to these effects, the areas of suction or blowing air can also be determined by the type of air supply or its activation or deactivation. Thus, the area supplied by the third air supply means corresponding to the recess can be shortened by switching off the air supply at an angle. Likewise, an area supplied by the third air supply means corresponding to the recesses can be divided into at least one suction area and at least one blowing area by switching the air supply between a suction air supply and a blowing air supply. The suction area on the outer surface of the stripping cylinder 4 serves to secure the blanks 10 or waste parts 9, while the blowing area is used to eject them.

[0164] According to a preferred embodiment, the third air supply means are designed to switch off the suction air supply or to switch between the suction air supply and the blowing air supply depending on the angular position of the respectively supplied third

[0165] Openings 32 are formed. Preferably, the third air supply means switches the air supply to the third openings 32 off or from suction air supply to blowing air supply when the respective third openings 32 reach a third release point due to rotation of the stripping cylinder 4 about its central axis.

[0166] The disc 18 is preferably connected to a frame via a torque support 20 and is rotatably mounted on the stripping cylinder 4. The stripping cylinder 4 is preferably rotatably mounted in the same frame to which the torque support 20 is hinged.

[0167] In order to shift the areas of suction or blowing air, which are formed on the outer surface of the stripping cylinder 4 in relation to the angle of rotation, actuators for rotating the disc 18 can be provided.

[0168] To facilitate assembly, the disc 18 preferably has a recess that allows radial displacement of the disc 18 for replacement purposes. The recess has an extension that is larger than the diameter of a pin of the stripping cylinder 4 in the area of ​​the stripping cylinder 4 in which the disc 18 is associated.

[0169] The stripping cylinder 4 and the transport cylinder 3 contribute to the treatment of substrates 1, in particular for separating or stripping processed, i.e. trimmed or cut, web-containing or perforated substrate 1 into at least one waste part 9 and at least one blank 10, preferably one pull-up 5 each. During the separation or stripping, remaining holding webs or material connections or material connections that were intentionally not completely cut through, in particular fibers or fiber bundles, are torn in the region of cutting lines between the waste part 9 and at least one blank 10. For this purpose, one of the pull-ups 5 can be designed as a female mold and the other pull-up 5 as a male mold. The male mold has a base plane and regions raised relative to the base plane. The raised regions act on the substrate 1 and form tools.The die has a base plane and, relative to the base plane, recessed areas or further recesses. The die and male die are arranged on the transport cylinder 3 or stripping cylinder 4 in such a way that the raised areas of the male die are opposite the recessed areas or further recesses of the die. The male die forms a kind of counterpart to the die. The female die is arranged either on the transport cylinder 3 or the stripping cylinder 4, and the male die on the other cylinder. The other cylinder in this sense is the cylinder that interacts with the cylinder carrying the die (transport cylinder 3 or stripping cylinder 4). Preferably, the female die is arranged on the transport cylinder 3, and the male die on the stripping cylinder. The male and female tool pair described above preferably differs from male and female tool pairs such as those used in cutting or perforating, e.g.on the processing cylinders upstream of the separating device 2. The structural design of the male die is determined by its function of merely pressing the elements to be separated or broken out into the recessed areas or the additional recesses of the female die. Accordingly, the raised areas of the male die can also have significantly smaller dimensions than the corresponding recessed areas or additional recesses of the female die. A flexographic printing plate can be used as the male die, in particular.

[0170] In an alternative embodiment, the male part does not have any raised areas relative to the base plane, but rather has an overall raised base plane. In this case, the male part is provided with an elastic coating or is made of an elastic material, at least on the side facing the female part.

[0171] During separation or breaking, waste parts 9 and blanks 10 are moved relative to one another, whereby residual webs or individual fibers or fiber bundles are torn apart in the area of ​​cutting lines. For this purpose, either the waste parts 9 or the blanks 10 are preferably pressed by the male mold into the recessed areas or the further recesses of the female mold. If a male mold with an elastic surface is used, the waste parts 9 are pressed into the recessed areas or the further recesses of the female mold, whereby the surface of the male mold expands at these points, while in areas of the surface outside the recesses or further recesses in the female mold, the substrate is pressed against the surface of the female mold.According to a further preferred embodiment, no stripping cylinder 4 is assigned to the transport cylinder 3, wherein in this embodiment too, the waste parts 9 and blanks 10 are moved relative to one another and residual webs or individual fibers or fiber bundles are torn in the region of cutting lines. The separating device 2 is preferably designed such that it acts exclusively on the side of the processed substrate 1 facing the transport cylinder 3, while the substrate 1 is transported on the transport cylinder 3. In a preferred embodiment, the separating device 2 is formed from raised areas and areas of the surface of the transport cylinder 3 that are depressed relative to the raised areas. The depressed areas are further preferably assigned first openings 12, which can be operatively connected to first air supply means 14. The first air supply means 14 are preferably designed to supply suction air.Further preferably, a cover 5 is interchangeably assigned to the outer surface of the transport cylinder 3, wherein the raised regions of the surface of the transport cylinder 3 are formed by the cover 5 and the recessed regions of the surface of the transport cylinder 3 are formed by the outer surface of the transport cylinder 3 in the region of openings formed in the cover 5. Second openings 13 can be formed in the raised regions and / or the recessed regions of the surface of the transport cylinder 3, which are operatively connected to second air supply means 15. Furthermore, the first and / or second air supply means 14, 15 can be switchable between a suction air supply and a blown air supply.

[0172] To achieve the relative movement of the waste parts 9 and blanks 10 relative to one another, the transport cylinder 3 can be assigned a lift 5, which is particularly designed in the manner of a die and has recessed areas or further perforations. In the area of ​​the recessed areas or further perforations, a negative pressure is applied via the first and / or second openings 12, 13, which moves the waste parts 9 and blanks 10 relative to one another, i.e., in particular, draws the waste parts 9 into the recessed areas or the further perforations while the blanks 10 are supported on the base plane of the die. Alternatively, it can also be provided to draw the blanks 10 into the recessed areas or the further perforations while the waste parts 9 are supported on the base plane of the die.In other words, the separation process is preferably effected solely by the force of the negative pressure or suction air applied in the recessed areas or further openings on the sides of the blanks 10 or waste parts 9 facing the transport cylinder 3. Openings are preferably arranged in the area of ​​the recessed areas. These ensure that the negative pressure applied at the first and / or second openings 12, 13 can spread to the side of the blanks 10 or waste parts 9 facing the transport cylinder 3.

[0173] When separating the substrate sheets 1 into waste parts 9 and blanks 10, problems arise, particularly in environments with low air humidity, which are caused by undesirable electrostatic charges on the waste parts 9 and / or blanks 10 and / or the surfaces of the transport cylinder 3 and / or stripping cylinder 4. As a result of the electrostatic charges, waste parts 9 and / or blanks 10 adhere to the surfaces of the transport cylinder 3 and / or stripping cylinder 4. In these cases, the effect of gravity is usually not sufficient to remove the waste parts 9 and / or blanks 10 from the cylinder surface or from the tools or tool parts fixed to the cylinder surfaces, in particular the male and female dies.

[0174] According to a further embodiment, which serves in particular to avoid problems caused by electrostatic charges, it is provided to form a separating device 2 which comprises a transport cylinder 3 and a stripping cylinder 4 associated therewith, wherein the transport cylinder 3 and / or the stripping cylinder 4 is associated with an antistatic device 95 ( Fig. 9 and Fig. 49, whereby the Fig. 49, the transport cylinder 3 is shown as an example). Preferably, the transport cylinder 3 has means for securing an exchangeable packing 5, as well as openings 12, 13 which, when the packing 5 is secured, are at least partially covered by openings that can be formed in the packing 5, wherein air supply means 14, 15 are provided for supplying the openings 12, 13 with air. The antistatic device 95 preferably comprises at least one electrode that is connected to at least one high-voltage source. The high-voltage source can be a positively or a negatively charged high-voltage source. Alternatively, the high-voltage source can be switched between an operating mode as a positive and an operating mode as a negative high-voltage source.The high-voltage sources can be connected via a controller to a sensor that detects the voltage applied to the surfaces of transport cylinder 3 and / or stripping cylinder 4 or the tools or tool parts attached to them. The controller is preferably designed to activate the positive or negative high-voltage source on a case-by-case basis or to switch the switchable high-voltage source depending on the sign of the applied voltage. The controller can also process the value of the applied voltage as a system parameter and control at least one high-voltage source depending on this system parameter. The described high-voltage sources preferably supply a pulsed or non-pulsed DC voltage.

[0175] The electrode of the antistatic device 95 preferably extends in the axial direction of the stripping cylinder 4 over its length and / or in the axial direction of the transport cylinder 3 over its length.

[0176] According to a further development, the antistatic device 95 comprises a brush, wherein the brush comprises a roller-shaped or strip-shaped base body, which is particularly electrically conductive. Bristles 105 are assigned to the base body. In the case of a roller-shaped design, the base body can be rotatably mounted.

[0177] In this case, the bristles 105 are preferably evenly distributed on the outer surface of the base body. If the base body is strip-shaped, it is fixedly arranged with respect to the surface of the cylinder to which it is assigned (transport cylinder 3 or stripping cylinder 4), at least in one operating position.

[0178] The bristles 105 are preferably made of an electrically conductive material, such as metal. A carbon compound can also be used as the material for the bristles 105. The bristles 105 are more preferably made of interwoven fibers or fiber bundles. These can be arranged next to one another in a row. Preferably, several of the described rows of interwoven fibers or fiber bundles are arranged one behind the other, viewed in the direction of rotation of the transport cylinder 3 or stripping cylinder 4. As an alternative to the assignment of bristles 105, a cloth 105 having electrically conductive fibers can also be assigned to the base body. The fibers can be woven into the cloth 105 or connected to the cloth 105, for example, by an adhesion promoter. In the developments in which bristles 105 or a cloth 105 are assigned to the base body, the bristles 105 orthe cloth 105 the electrode or are connected to the electrode.

[0179] The embodiments of antistatic devices 95 equipped with bristles 105 or a cloth 105 are arranged with respect to the transport cylinder 3 or stripping cylinder 4 such that they contact the outer surface of the respective cylinder. Preferably, a device is provided with which the antistatic device 95 can be displaced between an operating position in which the bristles 105 or the cloth 105 contact the outer surface of the respective cylinder and a parking position in which the bristles 105 or the cloth 105 do not contact the outer surface of the respective cylinder.

[0180] Furthermore or alternatively, in such developments, it is preferred that the antistatic device 95 comprises a blowing device which generates a volume flow of a gaseous medium ionized by at least one electrode in the direction of the outer surface of the transport cylinder 3 and / or the outer surface of the stripping cylinder 4.

[0181] Alternatively or in addition to the design of the separating device 2 with an antistatic device 95, the tools or tool parts used, such as the die and the patrix, and / or the cylinder surfaces of the transport cylinder 3 and / or a stripping cylinder 4 associated therewith can also be designed to be antistatic, in particular with electrically conductive materials.

[0182] According to another preferred embodiment with or without stripping cylinder 4, a circulating conveyor belt 29 is assigned to the transport cylinder 3, as can be seen in particular from Fig. 11 or Fig. 12. The conveyor belt 29 is preferably arranged above the transport cylinder 3. The conveyor belt 29 is assigned to the transport cylinder 3, preferably wrapping partially around the circumference, forming a wrap angle. Alternatively, the conveyor belt 29 can also be assigned to the transport cylinder 3, forming a tangent point 36. More preferably, the tangent point 36 is formed in the 12 o'clock position of the transport cylinder 3. The extension of the conveyor belt 29 is determined by the arrangement of deflection rollers. The conveyor belt 29 preferably has a horizontally extending transport region 37. The conveyor belt 29 can in particular be designed as a suction belt. More preferably, suction air is applied to the conveyor belt 29 at least in the transport region 37. This means that the conveyor belt 29 can be designed for the suspended transport of blanks and / or waste parts 10, 9.

[0183] The conveyor belt 29 has in particular the function of taking over processed substrate sheets 1, waste parts 9 or blanks 10 in the tangent point 36 or in the area of ​​the wrap of the conveyor belt 29 around the transport cylinder 3 and transporting them further.

[0184] Another transport system, for example in the form of a further transport belt 30, can be connected to the transport belt 29. Preferably, an overlapping area is formed between the transport belt 29 and the further transport belt 30, in which functionally processed substrate sheets 1 or blanks 10 and / or waste parts 9 can be transferred from the transport belt 29 to the further transport belt 30.

[0185] Further preferably, the further conveyor belt 30 is designed for the horizontal transport of useful and / or waste parts 10, 9.

[0186] It goes without saying that instead of the further conveyor belt 30, another suitable transport system can also be designed that takes over processed substrate sheets 1 or blanks 10 and / or waste parts 9 from the conveyor belt 29.

[0187] Instead of the additional conveyor belt 30, a container for receiving waste parts can also be arranged under the conveyor belt 30.

[0188] In addition to the conveyor belt 29, a further transport system 76 can also be directly assigned to the transport cylinder 3, i.e., forming a transfer area or transfer point between the transport cylinder 3 and the further transport system for processed substrate sheets 1 or blanks 10 and / or waste parts 9. This further transport system 76 is preferably designed as a sheet guide cylinder or sheet guide drum or chain conveyor system with gripper bars or a conveyor belt.

[0189] The operation of an embodiment as preferably provided by the Fig. 11 or Fig. 12. can be described as follows. The illustrated embodiment of the device for treating substrates is preferably a component of a sheet-fed printing press. The sheet-fed printing press can comprise one or more printing units. Further preferred are the Fig. 11 or Fig. 12. In the embodiment shown, two processing cylinders are arranged upstream, between which the substrate 1 can be inserted, wherein the substrate 1 undergoes processing when passing through tool parts from the group of cutting tools, punching tools, creasing tools, perforating tools that are active in the cylinder gap. One of the processing cylinders is in Fig. 11 or Fig. 12. shown as a semicircle. The processing cylinder is preferably designed as a sheet transport cylinder and has a sheet holding system. The sheet transport cylinder transfers a processed substrate sheet 1 to the transport cylinder 3 at the tangent point A between the transport cylinder 3 and the upstream sheet transport cylinder. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 1, while the gripper system, in particular the suction gripper system 17 of the transport cylinder 3 takes over the processed, in particular cut, substrate sheet 1. The substrate sheet 1 preferably comprises an edge and waste parts 9 connected to this via so-called residual webs, as well as blanks 10. The transport cylinder 3 carries a lifting device 5. The lifting device 5 has openings and is provided with depressions at the points where it acts on the blank 10.On the one hand, perforations are made in the area of ​​the blanks 10 at the points in the elevator 5 where first openings 12 are formed, wherein the second openings 13 in the area of ​​the blanks 10 are covered, i.e. closed, by the elevator 5. On the other hand, perforations are also made in the area of ​​the waste parts 9 at the points in the elevator 5 where second openings 13 are formed, wherein the first openings 12 in the area of ​​the waste parts 9 are covered, i.e. closed, by the elevator 5. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 3 or exactly at the tangent point A, the first air supply means 14 applies a negative pressure to the first openings 12, which fixes the blanks 10 to the outer surface of the transport cylinder 3 or to the elevator 5.As a result of the further rotation of the transport cylinder 3, the blanks 10, which have been fixed by the negative pressure, as well as the waste parts 9, reach the tangent point B, which is formed between the transport cylinder 3 and the stripping cylinder 4. At the tangent point B, the raised areas of the packing 5, which is arranged on the stripping cylinder 4, contact the surfaces of the waste parts 9 and press the waste parts 9 into the recesses of the packing 5 fixed on the transport cylinder 3. In the process, the remaining webs that connect the waste parts 9 to the frame or to the good parts 10 are torn apart. Preferably at the tangent point B, a negative pressure is applied via the second air supply means 15 to the second openings 13 in the area of ​​the waste parts 9, which fixes the waste parts 9 to the outer surface of the transport cylinder 3 or to the packing 5.Alternatively, the negative pressure can also be applied via the second air supply means 15 to the second openings 13 in the area of ​​the waste parts 9 at the tangential point A or immediately thereafter. When the respective blanks 10 reach the transfer point or transfer area C between the transport cylinder 3 and the conveyor belt 29, the first air supply means 14 are preferably deactivated. The negative pressure in the area of ​​the first openings 12 is no longer present and the blanks 10 are no longer fixed and thus released. As a result of the negative pressure preferably applied to the conveyor belt 29, the blanks 10 are lifted off the transport cylinder 3 at the transfer point or transfer area C, fixed to the underside of the conveyor belt 29 and transported away hanging thereon. The transfer of the blanks 10 from the transport cylinder 3 to the conveyor belt 29 can be assisted by applying an overpressure to the first openings 12.The supply to the first openings 12 is preferably switched from negative pressure to positive pressure when the first openings in the area of ​​the respective blanks 10 reach the transfer point or transfer area C. The removal of the blanks 10 can preferably be achieved with the additional conveyor belt 30. For this purpose, the conveyor belt 29 conveys the blanks 10 to the additional conveyor belt 30 and transfers the blanks 10 to the additional conveyor belt 30. For the transfer, the negative pressure applied to the conveyor belt 29 is preferably deactivated so that the blanks are fixed to the additional conveyor belt 30 under the effect of gravity or by additional suction and are transported away by the additional conveyor belt 30. When the waste parts 9 reach the release point D, the negative pressure applied to the second openings 13 in the area of ​​the waste parts 9 is deactivated or, preferably, an overpressure is applied instead of the negative pressure.This results in the release of the waste parts 9 or an active rejection of the waste parts 9, which can be picked up by a waste container. In the area of ​​release point D, in addition to the waste parts 9, preferably also the front edge of the substrate sheet 1 is released by the gripper system 17.

[0190] The further operation of an embodiment as preferably by the Fig. 11 or Fig. 12. can be described as follows. The sheet transport cylinder transfers a processed substrate sheet 1 to the transport cylinder 3 at the tangent point A between the transport cylinder 3 and the upstream sheet transport cylinder. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 1, while the gripper system, in particular the suction gripper system 17 of the transport cylinder 3 takes over the processed, in particular cut, substrate sheet 1. The substrate sheet 1 preferably comprises an edge and waste parts 9 connected to this via so-called residual webs, as well as blanks 10. The transport cylinder 3 carries a lifting device 5. The lifting device 5 has openings and is provided with depressions at the points where it acts on the blank 10.On the one hand, perforations are made in the area of ​​the blanks 10 at the points in the elevator 5 where first openings 12 are formed, wherein the second openings 13 in the area of ​​the blanks 10 are covered, i.e. closed, by the elevator 5. On the other hand, perforations are also made in the area of ​​the waste parts 9 at the points in the elevator 5 where second openings 13 are formed, wherein the first openings 12 in the area of ​​the waste parts 9 are covered, i.e. closed, by the elevator 5. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 3 or exactly at the tangent point A, the first air supply means 14 applies a negative pressure to the first openings 12, which fixes the blanks 10 to the outer surface of the transport cylinder 3 or to the elevator 5.As a result of the further rotation of the transport cylinder 3, the blanks 10, which are fixed by the negative pressure, as well as the waste parts 9 reach the tangent point B, which is formed between the transport cylinder 3 and the stripping cylinder 4. At the tangent point B, the raised areas of the packing 5, which is arranged on the stripping cylinder 4, contact the surfaces of the waste parts 9 and press the waste parts 9 into the recesses of the packing 5 fixed on the transport cylinder 3. In the process, the residual webs that connect the waste parts 9 to the frame or to the good parts 10 are torn. The packing 5 fixed on the stripping cylinder 4 has openings that correspond to the third openings 32 of the stripping cylinder 4. The openings are formed in the area of ​​the packing 5 in which it is not raised or in which it interacts with the blanks 10 in rolling contact.When the third openings 32 of the stripping cylinder 4 reach the tangent point B and are opposite a respective blank 10 at the tangent point B, a negative pressure is applied to them. As a result of this negative pressure, a force is exerted that lifts the blanks 10 from the surface of the transport cylinder 3. The negative pressure at the third openings 32 of the stripping cylinder 4 is deactivated as soon as they have left the area of ​​the tangent point B again or a few degrees, in particular 10 degrees, thereafter. Preferably, the negative pressure applied to the first openings 12 is deactivated when the respective first openings 12 are in the area of ​​the tangent point B.This ensures that the respective blank 10 is briefly lifted from the surface of the transport cylinder 3 under the effect of the negative pressure at the third openings 32 of the stripping cylinder 4, i.e. for a few angular degrees, in particular 10 degrees of the rotational movement of the transport cylinder 3. This measure additionally supports the separation of the blank 10 and waste parts 9, since these are actively moved in different directions, at least for a short time. Preferably at the tangential point B, a negative pressure is applied via the second air supply means 15 to the second openings 13 in the area of ​​the waste parts 9, which fixes the waste parts 9 to the outer surface of the transport cylinder 3 or to the elevator 5. Alternatively, the negative pressure can also be applied via the second air supply means 15 to the second openings 13 in the area of ​​the waste parts 9 at the tangential point A or immediately thereafter.When the respective blanks 10 reach the transfer point or transfer area C between transport cylinder 3 and conveyor belt 29, the first air supply means 14 are preferably deactivated. The negative pressure in the area of ​​the first openings 12 is no longer present and the blanks 10 are no longer fixed and thus released. As a result of the negative pressure preferably present on the conveyor belt 29, the blanks 10 are lifted off the transport cylinder 3 at the transfer point or transfer area C, fixed to the underside of the conveyor belt 29 and transported away hanging thereon. The transfer of the blanks 10 from the transport cylinder 3 to the conveyor belt 29 can be assisted by applying positive pressure to the first openings 12. The supply to the first openings 12 is preferably switched from negative pressure to positive pressure when the first openings in the area of ​​the respective blanks 10 reach the transfer point or transfer area C.The removal of the blanks 10 can preferably be achieved with the additional conveyor belt 30. For this purpose, the conveyor belt 29 conveys the blanks 10 to the additional conveyor belt 30 and transfers the blanks 10 to the additional conveyor belt 30. For the transfer, the negative pressure applied to the conveyor belt 29 is preferably deactivated so that the blanks are fixed to the additional conveyor belt 30 under the effect of gravity or by additional suction and are transported away by this. When the waste parts 9 reach the release point D, the negative pressure applied to the second openings 13 in the area of ​​the waste parts 9 is deactivated or, preferably, an overpressure is applied instead of the negative pressure. This releases the waste parts 9 or actively rejects the waste parts 9, which can be picked up by a waste container.In the area of ​​release point D, in addition to the waste parts 9, preferably also the front edge of the substrate sheet 1 is released by the gripper system 17.

[0191] A further mode of operation of an embodiment as preferably provided by the Fig. 11 or Fig. 12. is illustrated, relates to full-sheet processing or full-sheet inspection and is described below. The sheet transport cylinder transfers a processed substrate sheet 1 to the transport cylinder 3 at the tangent point A between the transport cylinder 3 and the upstream sheet transport cylinder. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 1, while the gripper system, in particular the suction gripper system 17 of the transport cylinder 3 takes over the processed, in particular trimmed, substrate sheet 1. The substrate sheet 1 preferably comprises an edge and waste parts 9 connected to this via so-called residual webs, as well as blanks 10. The transport cylinder 3 carries a cover 5. The cover 5 has openings. The openings are made at the points in the cover 5 where first and / or second openings 12, 13 are formed.When the first and / or second openings 12, 13 have passed the tangent point A as a result of the rotation of the transport cylinder 3 or exactly at the tangent point A, a negative pressure is applied to the first and / or second openings 12, 13 by the first and / or second air supply means 14, 15, which fixes only the blanks 10 or only the waste parts 9 or the blanks 10 and the waste parts 9 to the outer surface of the transport cylinder 3 or to the elevator 5. As a result of the further rotation of the transport cylinder 3, the blanks 10 and the waste parts 9 pass the tangent point B. Contact between the waste parts 9 or the blanks and other elements does not occur at the tangent point B. When the respective blanks 10 and the respective waste parts 9 reach the transfer point or transfer area C between the transport cylinder 3 and the conveyor belt 29, the first and / or second air supply means 14, 15 are preferably deactivated.The negative pressure in the area of ​​the first and / or openings 12, 13 is no longer present and the blanks 10 and the waste parts 9 are no longer fixed and thus released. The fixing of the leading edges of the substrate sheets 1 by the gripper system 17 is also released at the transfer point or transfer area C. As a result of the negative pressure preferably applied to the conveyor belt 29, the blanks 10 and the waste parts 9 and the frames of the substrate sheets 1, including the leading edges of the substrate sheets 1, which are still connected to one another by the remaining webs (full sheet), are lifted off the transport cylinder 3 at the transfer point or transfer area C, fixed to the underside of the conveyor belt 29 and transported away hanging thereon.The transfer of the blanks 10 and the waste parts 9 and the frames of the substrate sheets 1, including the leading edges of the substrate sheets 1, as a whole sheet from the transport cylinder 3 to the transport belt 29 can be assisted by applying an overpressure to the first and / or second openings 12, 13. The supply to the first and / or second openings 12, 13 is preferably switched from negative pressure to positive pressure when the first and / or second openings 12, 13 reach the transfer point or transfer area C.

[0192] The removal of the full sheets can preferably be achieved with the additional conveyor belt 30. For this purpose, the conveyor belt 29 conveys the full sheets to the additional conveyor belt 30 and transfers the full sheets to the additional conveyor belt 30. For the transfer, the negative pressure applied to the conveyor belt 29 is preferably deactivated, so that the full sheets are fixed to the additional conveyor belt 30 under the effect of gravity or by additional suction and are transported away by the additional conveyor belt 30.

[0193] According to another preferred embodiment with stripping cylinder 4, a circulating conveyor belt 29 is associated with the stripping cylinder, as can be seen in particular from Fig. 13 can be seen. The conveyor belt 29 is preferably arranged above the transport cylinder 3. The conveyor belt 29 is assigned to the stripping cylinder 4, preferably forming a transfer point 38 or transfer area. More preferably, the conveyor belt 29 is arranged to partially wrap around the stripping cylinder 4, forming a wrap angle. Particularly preferably, the transfer point 38 or the transfer area is formed in the 8 o'clock position of the stripping cylinder 4 and the stripping cylinder 4 is assigned to the transport cylinder 3 in the 12 o'clock position of the transport cylinder 3. The extension of the conveyor belt 29 is determined by the arrangement of deflection rollers. The conveyor belt 29 preferably has a first transport area 39 which extends at least approximately tangentially to the stripping cylinder 4. More preferably, the first transport area 39 is inclined at an angle of between 30 and 60 degrees to the horizontal.The conveyor belt 29 preferably has a second transport area 40 which runs at least approximately horizontally, in particular exactly horizontally. In particular, the conveyor belt 29 is a suction belt and the first transport area 39 is an area in which suction air is applied to the conveyor belt 29. The conveyor belt 29 has the particular function of receiving processed substrate sheets 1, waste parts 9 or blanks 10 from the stripping cylinder 4 at the transfer point 38 or transfer area between the conveyor belt 29 and the stripping cylinder 4 and transporting them further. Another transport system, for example in the form of a further conveyor belt 30, can be connected to the conveyor belt 29. An overlap area is preferably formed between the conveyor belt 29 and the further conveyor belt 30, in which overlap area the processed substrate sheets 1 or blanks 10 and / or waste parts 9 can be transferred from the conveyor belt 29 to the further conveyor belt 30.It goes without saying that instead of the further conveyor belt 30, another suitable transport system can also be designed which takes over processed substrate sheets 1 or blanks 10 and / or waste parts 9 from the conveyor belt 29. In addition to the conveyor belt 29, a further transport system 76 can also be assigned directly to the transport cylinder 3, i.e., forming a transfer area or transfer point between the transport cylinder 3 and the further transport system 76 for processed substrate sheets 1 or blanks 10 and / or waste parts 9. This further transport system 76 is preferably designed as a sheet guiding cylinder or sheet guiding drum or chain conveyor system with gripper bridges or conveyor belt. The stripping cylinder 5 preferably has third openings 32 and third air supply means for supplying the third openings 32 with air.The third air supply means are preferably switchable between a suction air supply and a blown air supply. In particular, the third air supply means are designed to switch between suction air supply and blown air supply depending on the angular position of the respective supplied third openings 32. Further preferably, the third air supply means are designed to switch the air supply of the third openings 32 from suction air supply to blown air supply when the respective third openings 32 reach a third release point, in particular the transfer point or transfer area between the stripping cylinder 4 and the conveyor belt 29, due to rotation of the stripping cylinder 4 about its axis of rotation. The third openings 32 can be groove-shaped or hole-shaped.The third air supply means preferably comprise a rotary valve or a rotary inlet, wherein the at least one rotary valve or the at least one rotary inlet can be formed on the front side of the stripping cylinder 4. Like the transport cylinder 3, the stripping cylinder 4 preferably has means for securing an exchangeable packing 5. The securing means are preferably designed as clamping grippers. With them, a respective packing 5 can be secured at the rear edge and at the front edge. The means for securing the front edge of the packing 5 are preferably formed by the front edge clamping element 22 and the further clamping element 24 which cooperates correlatively with the front edge to form a clamping gap. The front edge clamping element 22 is mounted on the base body of the stripping cylinder 4. The further clamping element 24 can in particular be formed as a leaf spring assembly.Adjacent to the additional clamping element 24 is an actuating element 25, preferably designed as a pneumatic muscle. The actuating element is preferably connected to an air supply, with which overpressure can be applied to the actuating element 25. The rear edge of the packing 5 can be fixed between a rear edge clamping element 47 and another rear edge clamping element 48, which together form a further clamping gap. The force required to close the rear edge clamping gripper is applied by a rotatable tensioning shaft 50, which acts on the rear edge clamping element 47 via a toggle lever 51.

[0194] Further preferred details of the stripping cylinder 4 are shown in Fig. 10 and the associated description, to which reference is made in connection with the described embodiment. A packing 5 with perforations is preferably fixed to the stripping cylinder 4. The perforations in the packing 5 of the stripping cylinder 4 correspond to the third openings 32 of the stripping cylinder 4. The perforations are preferably formed in the region of the packing 5 in which it is not raised and interacts with the blank 10 in rolling contact. When the third openings 32 of the stripping cylinder 4 reach the tangent point B and are opposite a respective blank 10 at the tangent point B, a negative pressure is applied to them. As a result of this negative pressure, a force is exerted which lifts the blanks 10 from the surface of the transport cylinder 3.

[0195] A preferred mode of operation of an embodiment as preferably provided by the Fig. 13, can be described as follows. The sheet transport cylinder transfers a processed substrate sheet 1 to the transport cylinder 3 at the tangent point A between the transport cylinder 3 and the upstream sheet transport cylinder. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 1, while the gripper system, in particular the suction gripper system 17 of the transport cylinder 3 takes over the processed, in particular cut, substrate sheet 1. The substrate sheet 1 preferably comprises an edge and waste parts 9 connected to this via so-called residual webs, as well as blanks 10. The transport cylinder 3 carries a lift 5. The lift 5 has openings and is provided with depressions at the points where it acts on the blank 10.Perforations are preferably made, on the one hand, in the area of ​​the blanks 10 at the points in the elevator 5 where first openings 12 are formed, wherein the second openings 13 in the area of ​​the blanks 10 are covered, i.e., closed, by the elevator 5. Perforations are preferably also made, on the other hand, in the area of ​​the waste parts 9 at the points in the elevator 5 where second openings 13 are formed, wherein the first openings 12 in the area of ​​the waste parts 9 are covered, i.e., closed, by the elevator 5. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 3, or exactly at the tangent point A, the first air supply means 14 applies a negative pressure to the first openings 12, which fixes the blanks 10 to the outer surface of the transport cylinder 3 or to the elevator 5.As a result of the further rotation of the transport cylinder 3, the blanks 10, which are fixed by the negative pressure, as well as the waste parts 9 reach the tangent point B, which is formed between the transport cylinder 3 and the stripping cylinder 4. At the tangent point B, the raised areas of the packing 5, which is arranged on the stripping cylinder 4, contact the surfaces of the waste parts 9 and press the waste parts 9 into the recesses of the packing 5 fixed on the transport cylinder 3. In the process, the residual webs that connect the waste parts 9 to the frame or to the good parts 10 are torn. The packing 5 fixed on the stripping cylinder 4 has openings that correspond to the third openings 32 of the stripping cylinder 4. The openings are preferably formed in the area of ​​the packing 5 in which it is not raised or in which it interacts with the blanks 10 in rolling contact.When the third openings 32 of the stripping cylinder 4 reach the tangent point B and are opposite a respective blank 10 at the tangent point B or immediately in front of it, a negative pressure is applied to them. As a result of this negative pressure, a force is exerted which lifts the blanks 10 from the surface of the transport cylinder 3. Preferably, the negative pressure applied to the first openings 12 of the transport cylinder 3 is deactivated when the respective first openings 12 are located in the region of the tangent point B. This ensures that the respective blank 10 is lifted from the surface of the transport cylinder 3 under the effect of the negative pressure at the third openings 32 of the stripping cylinder. The negative pressure applied to the second openings 13 is maintained when the respective second openings 13 pass the tangent point B.As a result, the waste parts 9 are held on the surface of the transport cylinder 4 and transported past the tangent point B, while the blanks 10 are transferred from the transport cylinder 3 to the stripping cylinder 4 at the tangent point B. As a result of its rotation, the stripping cylinder 4 transports the blanks 10, which are fixed by negative pressure, further in the direction of the conveyor belt 29 until they reach the transfer point or transfer area E of the stripping cylinder 4 and conveyor belt 29. At the transfer point or transfer area E of the stripping cylinder 4 and conveyor belt 29, a suction effect is preferably exerted on the side of the blanks 10 facing away from the stripping cylinder 4 by the conveyor belt 29, which is preferably designed as a suction belt. When the respective third openings 32 reach the transfer point or transfer area E, the negative pressure applied to them is also deactivated.Preferably, following deactivation of the negative pressure at the third openings 32, an overpressure can be built up. Due to the described forces, the respective blanks 10 are transferred from the stripping cylinder 4 to the conveyor belt 29 at the transfer point or transfer area E. The conveyor belt 29 runs on deflection rollers, at least one of which is driven, and transports the blanks 10 preferably to a stacking device or depositing device (not shown). After passing the transfer point or transfer area E through the third openings 32, the negative pressure applied to them can be deactivated. The deactivation ends at the latest when the third openings 32 return to the tangent point B.Preferably at tangential point B, a negative pressure is applied via the second air supply means 15 to the second openings 13 in the area of ​​the waste parts 9, which fixes the waste parts 9 to the outer surface of the transport cylinder 3 or to the elevator 5. Alternatively, the negative pressure can also be applied via the second air supply means 15 to the second openings 13 in the area of ​​the waste parts 9 already at tangential point A or immediately thereafter. When the waste parts 9 reach the release point D, the negative pressure present at the second openings 13 in the area of ​​the waste parts 9 is deactivated or, preferably, an overpressure is applied instead of the negative pressure. This releases the waste parts 9 or actively repels the waste parts 9, which can be picked up by a waste container. In the area of ​​release point D, in addition to the waste parts 9, the front edge of the substrate sheet 1 is preferably also released by the gripper system 17.

[0196] A further mode of operation of an embodiment as preferably provided by the Fig. 13, relates to full-sheet processing or full-sheet inspection and is described below. The sheet transport cylinder transfers a processed substrate sheet 1 to the transport cylinder 3 at the tangent point A between the transport cylinder 3 and the upstream sheet transport cylinder. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 1, while the gripper system, in particular the suction gripper system 17 of the transport cylinder 3 takes over the processed, in particular cut, substrate sheet 1. The substrate sheet 1 preferably comprises an edge and waste parts 9 connected to this via so-called residual webs, as well as blanks 10. The transport cylinder 3 carries a cover 5. The cover 5 has openings. The openings are made at the points in the cover 5 where first and / or second openings 12, 13 are formed.When the first and / or second openings 12, 13 have passed the tangent point A as a result of the rotation of the transport cylinder 3 or exactly at the tangent point A, a negative pressure is applied by the first and / or second air supply means 14, 15 to the first and / or second openings 12, 13, which fixes only the blanks 10 or only the waste parts 9 or the blanks 10 and the waste parts 9 to the outer surface of the transport cylinder 3 or to the elevator 5. When the respective blanks 10 and the respective waste parts 9 reach the tangent point B as a result of the further rotation of the transport cylinder 3, the first and / or second air supply means 14, 15 are preferably deactivated. The negative pressure in the region of the first and / or second openings 12, 13 is no longer present and the blanks 10 and the waste parts 9 are no longer fixed and are thus released.The fixation of the leading edges of the substrate sheets 1 by the gripper system 17 is also released at the tangent point B. When the third openings 32 of the stripping cylinder 4 reach the tangent point B and are located opposite or immediately in front of a respective blank 10 at the tangent point B, a negative pressure is applied to them. As a result of this negative pressure, a force is exerted that lifts the blanks 10 from the surface of the transport cylinder 3. Preferably, the negative pressure applied to the first and / or second openings 12, 13 of the transport cylinder 3 is deactivated when the respective first and / or second openings 12, 13 are located in the region of the tangent point B.As a result of the negative pressure preferably applied to the third openings 32, the blanks 10 and the waste parts 9 and the frames of the substrate sheets 1, including the front edges of the substrate sheets 1, which are still connected to one another by the remaining webs (full sheet), are lifted off the transport cylinder 3 at the tangent point B and transferred to the stripping cylinder 4. The transfer of the blanks 10 and the waste parts 9 and the frames of the substrate sheets 1, including the front edges of the substrate sheets 1, as a full sheet from the transport cylinder 3 to the stripping cylinder 4 can be assisted by applying positive pressure to the first and / or second openings 12, 13. The supply to the first and / or second openings 12, 13 is preferably switched from negative pressure to positive pressure when the first and / or second openings 12, 13 reach the tangent point B.The stripping cylinder 4 transports the full sheets, which are held in place by negative pressure, further in the direction of the conveyor belt 29 as a result of its rotation until they reach the transfer point or transfer area E of the stripping cylinder 4 and the conveyor belt 29. At the transfer point or transfer area E of the stripping cylinder 4 and the conveyor belt 29, a suction effect is preferably exerted on the side of the full sheets facing away from the stripping cylinder 4 by the conveyor belt 29, which is preferably designed as a suction belt. When the respective third openings 32 reach the transfer point or transfer area E, the negative pressure applied to them is also deactivated. Preferably, following the deactivation of the negative pressure at the third openings 32, an overpressure can be built up. As a result of the described forces, the full sheets are transferred from the stripping cylinder 4 to the conveyor belt 29 at the transfer point or transfer area E.The conveyor belt 29 runs on deflection rollers, at least one of which is driven, and transports the full sheets preferably to a stacking device or depositing device (not shown). After passing the transfer point or transfer area E through the third openings 32, the negative pressure applied to them can be deactivated. The deactivation ends at the latest when the third openings 32 return to the tangent point B. According to another preferred embodiment, with or without a stripping cylinder 4, a peeling device 31 (also called a peeling apparatus) is assigned to the transport cylinder 3, as can be seen in particular from FIG. Fig. 14 can be seen. The peeling device 31 preferably has a support surface which extends in the direction of a virtual tangent applied to the transport cylinder 3. The support surface can be aligned horizontally. The peeling device 31 is further preferably assigned a circulating conveyor belt 29 which can be designed as a suction belt circulating over deflection rollers. The peeling device 31 is preferably assigned to the transport cylinder 3 in its 12 o'clock position or, viewed in the direction of rotation of the transport cylinder 3, immediately adjacent to its 11 o'clock position. The conveyor belt 29 preferably has a transport region 37 which is inclined horizontally or at an angle of less than 10 degrees to the horizontal. According to a preferred embodiment, the support surface formed on the peeling device 31 and the transport region 37 lie in one and the same virtual plane.Further preferably, the support surface and the transport area 37 extend in the direction of a virtual tangent applied to the transport cylinder 3.

[0197] The transport cylinder 3 and the optional stripping cylinder 4 can be designed according to those embodiments of transport cylinder 3 and stripping cylinder 4 as they are particularly used in connection with the objects according to the Fig. 9 to 13 have already been described.

[0198] The peeling device 31 has the particular function of lifting processed substrate sheets 1, waste parts 9, or blanks 10 from the surface of the transport cylinder 3 or the surface of the elevator 5 associated with it with the aid of the peeling device 31 and feeding them to the conveyor belt 29, which transports them away. Another transport system, for example in the form of a further conveyor belt 30, can be connected to the conveyor belt 29. Preferably, an overlap region is formed between the conveyor belt 29 and the further conveyor belt 30, in which processed substrate sheets 1 or blanks 10 and / or waste parts 9 can be transferred from the conveyor belt 29 to the further conveyor belt 30.

[0199] It goes without saying that instead of the further conveyor belt 30, another suitable transport system can also be designed which takes over the processed substrate sheets 1 or blanks 10 and / or waste parts 9 from the conveyor belt 29.

[0200] Instead of the additional conveyor belt 30, a container for receiving waste parts 9 can also be arranged under the conveyor belt 29.

[0201] In addition to the conveyor belt 29, a further conveyor system 76 can also be directly assigned to the conveyor cylinder 3, i.e., forming a transfer area or transfer point between the conveyor cylinder 3 and the further conveyor system 76 for processed substrate sheets 1 or blanks 10 and / or waste parts 9. This further conveyor system 76 is preferably designed as a sheet guide cylinder or sheet guide drum or chain conveyor system with gripper bars or conveyor belt.

[0202] The operation of an embodiment as preferably provided by the Fig. 14 can be described as follows. The illustrated embodiment of the device for treating substrates 1 is preferably a component of a sheet-fed printing press. The sheet-fed printing press can comprise one or more printing units 6. Further preferred are the Fig. 14. In the embodiment shown, two processing cylinders are arranged upstream, between which the substrate 1 can be inserted, wherein the substrate 1 undergoes processing as it passes through tool parts from the group of cutting tools, punching tools, creasing tools, perforating tools that are active in the cylinder gap. One of the processing cylinders is in Fig. 14. shown as a semicircle. The processing cylinder is preferably designed as a sheet transport cylinder and has a sheet holding system. The sheet transport cylinder transfers a processed substrate sheet 1 to the transport cylinder 3 at the tangent point A between the transport cylinder 3 and the upstream sheet transport cylinder. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 1, while the gripper system 17, in particular the suction gripper system 17, of the transport cylinder 3 takes over the processed, in particular trimmed, substrate sheet 1. The substrate sheet 1 preferably comprises an edge and waste parts 9 connected to this via so-called residual webs, as well as blanks 10. The transport cylinder 3 carries a lifting device 5. The lifting device 5 has openings and is provided with depressions at the points where it acts on the blank 10.On the one hand, perforations are made in the area of ​​the blanks 10 at the points in the elevator 5 where first openings 12 are formed, wherein the second openings 13 in the area of ​​the blanks 10 are covered, i.e. closed, by the elevator 5. On the other hand, perforations are also made in the area of ​​the waste parts 9 at the points in the elevator 5 where second openings 13 are formed, wherein the first openings 12 in the area of ​​the waste parts 9 are covered, i.e. closed, by the elevator 5. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 3 or exactly at the tangent point A, the first air supply means 14 applies a negative pressure to the first openings 12, which fixes the blanks 10 to the outer surface of the transport cylinder 3 or to the elevator 5.As a result of the further rotation of the transport cylinder 3, the blanks 10, which have been fixed by the negative pressure, as well as the waste parts 9, reach the tangent point B, which is formed between the transport cylinder 3 and the stripping cylinder 4. At the tangent point B, the raised areas of the packing 5, which is arranged on the stripping cylinder 4, contact the surfaces of the waste parts 9 and press the waste parts 9 into the recesses of the packing 5 fixed on the transport cylinder 3. In the process, the remaining webs that connect the waste parts 9 to the frame or to the good parts (blanks) 10 are torn. Preferably at the tangent point B, a negative pressure is applied via the second air supply means 15 to the second openings 13 in the area of ​​the waste parts 9, which fixes the waste parts 9 to the outer surface of the transport cylinder 3 or to the packing 5.Alternatively, the negative pressure can be applied via the second air supply means 15 to the second openings 13 in the area of ​​the waste parts 9 even at the tangential point A or immediately thereafter. As a result of the rotation of the transport cylinder 3, the blanks 10 and the waste parts 9 are transported past the tangential point B until they finally reach the transfer point F between the transport cylinder 3 and the peeling device 31. Before the respective blanks 10 reach the transfer point F between the transport cylinder 3 and the peeling device 31, the first air supply means 14 of the transport cylinder 3 are switched from a suction air supply to a blown air supply. The negative pressure in the area of ​​the first openings 12 is reduced, so that the blanks 10 are no longer fixed and, as the overpressure builds up at the first openings 12, they are pushed off the surface of the transport cylinder 3 or its elevator 5.This means that at least the front edges of the blanks 10, viewed in the direction of rotation of the transport cylinder 3, protrude beyond the peeling device 31 in the radial direction of the transport cylinder 3. The peeling device 31 is aimed at the gap formed between the front edges of the blanks 10 and the surface of the transport cylinder 3 or its elevator 5. As a result of the rotation of the transport cylinder 3, the blanks 10 are pushed onto the support surface of the peeling device 31 until they reach the capture area of ​​the conveyor belt 29, which transports the blanks 10 away. In contrast to the first openings 12, the negative pressure applied to the second openings 13 is maintained by the second air supply means 15 when the second openings 13 pass the tangent point B until they reach the release point D. Upon reaching the release point D, the negative pressure applied to the second openings 13 is deactivated.In a preferred embodiment, an additional overpressure can be applied to the second openings 13 when the second openings 13 reach the area of ​​the release point D. With the aforementioned method steps, not only is the fixation of the waste parts 9 terminated upon reaching the release point D, but the lifting of the waste parts 9 is preferably assisted by pneumatic means in addition to the force of gravity. In the area of ​​the release point D, in addition to the waste parts 9, preferably the leading edge of the substrate sheet 1 is also released by the gripper system 17.

[0203] A further mode of operation of an embodiment as preferably provided by the Fig. 14, relates to full-sheet processing or full-sheet inspection and is described below. The sheet transport cylinder transfers a processed substrate sheet 1 to the transport cylinder 3 at the tangent point A between the transport cylinder 3 and the upstream sheet transport cylinder. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 1, while the gripper system 17, in particular the suction gripper system 17, of the transport cylinder 3 takes over the processed, in particular cut, substrate sheet 1. The substrate sheet 1 preferably comprises an edge and waste parts 9 connected to this via so-called residual webs, as well as blanks 10. The transport cylinder 3 carries a cover 5. The cover 5 has openings. The openings are made at the points in the cover 5 where first and / or second openings 12, 13 are formed.When the first and / or second openings 12, 13 have passed the tangent point A as a result of the rotation of the transport cylinder 3 or are located exactly at the tangent point A, a negative pressure is applied to the first and / or second openings 12, 13 by the first and / or second air supply means 14, 15, which fixes only the blanks 10 or only the waste parts 9 or the blanks 10 and the waste parts 9 to the outer surface of the transport cylinder 3 or to the elevator 5. As a result of the further rotation of the transport cylinder 3, the blanks 10 and the waste parts 9 pass the tangent point B. Contact between the waste parts 9 or the blanks 10 and other elements does not occur at the tangent point B. The stripping cylinder 4 is switched off from the transport cylinder 3.When the respective blanks 10 and the respective waste parts 9 reach the transfer point F between the transport cylinder 3 and the peeling device 31, the first and / or second air supply means 14, 15 are deactivated or preferably switched to blast air supply. The negative pressure in the area of ​​the first and / or second openings 12, 13 is no longer present and the blanks 10 and the waste parts 9 and the frames of the substrate sheets 1, including the front edges of the substrate sheets 1, which are still connected to one another by the residual webs (full sheet), are no longer fixed and are thus released at the transfer point F and preferably lifted off in a targeted manner from the surface of the transport cylinder 3 or from the elevator 5. The fixing of the front edges of the substrate sheets 1 by the gripper system 17 is also released at the transfer point or transfer area C.As a result of the rotation of the transport cylinder 3, the full sheets are then pushed over the support surface of the peeling device 31 until they reach the effective area of ​​the conveyor belt 29, from which they are transported away.

[0204] The operation of an embodiment as preferably provided by the Fig. 15, can be described as follows. The sheet transport cylinder transfers a processed substrate sheet 1 to the transport cylinder 3 at the tangent point A between the transport cylinder 3 and the upstream sheet transport cylinder. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 1, while the gripper system 17, in particular the suction gripper system 17, of the transport cylinder 3 takes over the processed, in particular cut, substrate sheet 1. The substrate sheet 1 preferably comprises an edge and waste parts 9 connected to this via so-called residual webs, as well as blanks 10. The transport cylinder 3 carries a lift 5. The lift 5 has openings and is provided with depressions at the points where it acts on the blank 10.On the one hand, perforations are made in the area of ​​the blanks 10 at the points in the elevator 5 where first openings 12 are formed, wherein the second openings 13 in the area of ​​the blanks 10 are covered, i.e. closed, by the elevator 5. On the other hand, perforations are also made in the area of ​​the waste parts 9 at the points in the elevator 5 where second openings 13 are formed, wherein the first openings 12 in the area of ​​the waste parts 9 are covered, i.e. closed, by the elevator 5. When the first openings 12 have passed the tangent point A as a result of the rotation of the transport cylinder 3 or are located exactly at the tangent point A, the first air supply means 14 applies a negative pressure to the first openings 12, which fixes the blanks 10 to the outer surface of the transport cylinder 3 or to the elevator 5.As a result of the further rotation of the transport cylinder 3, the blanks 10, which are fixed by the negative pressure, as well as the waste parts 9 reach the tangent point B, which is formed between the transport cylinder 3 and the stripping cylinder 4. At the tangent point B, the raised areas of the packing 5, which is arranged on the stripping cylinder 4, contact the surfaces of the waste parts 9 and press the waste parts 9 into the recesses of the packing 5 fixed on the transport cylinder 3. In the process, the residual webs that connect the waste parts 9 to the frame or to the good parts 10 are torn. The packing 5 fixed on the stripping cylinder 4 has openings that correspond to the third openings 32 of the stripping cylinder 4. The openings are formed in the area of ​​the packing 5 in which it is not raised or in which it interacts with the blanks 10 in rolling contact.When the third openings 32 of the stripping cylinder 4 reach the tangent point B and are opposite a respective blank 10 at the tangent point B, a negative pressure is applied to them. As a result of this negative pressure, a force is exerted that lifts the blanks 10 from the surface of the transport cylinder 3. The negative pressure at the third openings 32 of the stripping cylinder 4 is deactivated as soon as they have left the area of ​​the tangent point B again or a few degrees, in particular 10 degrees, thereafter. Preferably, the negative pressure applied to the first openings 12 is deactivated when the respective first openings 12 are in the area of ​​the tangent point B.This ensures that the respective blank 10 is briefly lifted from the surface of the transport cylinder 3 under the effect of the negative pressure at the third openings 32 of the stripping cylinder 4, i.e. for a few angular degrees, in particular 10 degrees of the rotational movement of the transport cylinder 3. This measure additionally supports the separation of the blank 10 and waste parts 9, since these are actively moved in different directions, at least for a short time. Preferably at the tangential point B, a negative pressure is applied via the second air supply means 15 to the second openings 13 in the area of ​​the waste parts 9, which fixes the waste parts 9 to the outer surface of the transport cylinder 3 or to the elevator 5. Alternatively, the negative pressure can also be applied via the second air supply means 15 to the second openings 13 in the area of ​​the waste parts 9 at the tangential point A or immediately thereafter.As a result of the rotation of the transport cylinder 3, the blanks 10 and the waste parts 9 are transported past the tangential point B until they finally reach the transfer point F between the transport cylinder 3 and the peeling device 31. Before the respective blanks 10 reach the transfer point F between the transport cylinder 3 and the peeling device 31, the first air supply means 14 of the transport cylinder 3 are switched from a suction air supply to a blown air supply. The negative pressure in the region of the first openings 12 is reduced, so that the blanks 10 are no longer fixed and, as the overpressure builds up at the first openings 12, are pushed off the surface of the transport cylinder 3 or its elevator 5. As a result, at least the front edges of the blanks 10, viewed in the direction of rotation of the transport cylinder 3, protrude beyond the peeling device 31 in the radial direction of the transport cylinder 3.The peeling device 31 is aimed at the gap formed between the front edges of the blanks 10 and the surface of the transport cylinder 3 or its elevator 5. As a result of the rotation of the transport cylinder 3, the blanks 10 are pushed onto the support surface of the peeling device 31 until they reach the detection area of ​​the conveyor belt 29, which transports the blanks 10 away. In contrast to the first openings 12, the negative pressure applied to the second openings 13 is maintained by the second air supply means 15 when the second openings 13 pass the tangent point B until they reach the release point D. Upon reaching the release point D, the negative pressure applied to the second openings 13 is deactivated. In a preferred embodiment, an additional positive pressure can be applied to the second openings 13 when the second openings 13 reach the area of ​​the release point D.With the aforementioned process steps, not only is the fixation of the waste parts 9 terminated upon reaching the release point D, but the lifting of the waste parts 9 is preferably supported by pneumatic means in addition to the force of gravity. In the area of ​​the release point D, in addition to the waste parts 9, preferably also the leading edge of the substrate sheet 1 is released by the gripper system 17.

[0205] Instead of the conveyor belt 29, a further conveyor system 76 can also be assigned directly to the conveyor cylinder 3, ie, forming a transfer area or transfer point between the conveyor cylinder 3 and the further conveyor system 76 for processed substrate sheets 1 or blanks 10 and / or waste parts 9. This further conveyor system 76 is preferably designed as a sheet guiding cylinder or sheet guiding drum or sheet guiding system, in particular a chain conveyor system with gripper bars, or a conveyor belt. An embodiment with a chain conveyor system with gripper bars as a component of the delivery 99 of a sheet-fed printing press is described in Fig. 17 shown.

[0206] The chain conveyor system contains traction means moved via drive and deflection means, which drive gripping devices, in particular gripper bridges, for conveying the substrate. The gripping devices have fixing elements for receiving and fixing the sheet-shaped substrates 1. Clamping and / or suction grippers for gripping the substrate edges can be used as fixing elements. In further developments not shown, additional gripping devices are provided for the substrate trailing edges. The sheet conveyor system, designed here as a chain conveyor system, contains chains laid over and driven by sprockets, guided in laterally arranged guide rails (not shown), on which gripper bridges are arranged for transporting the substrates 1. The gripper bridges convey the substrates 1 in the transport direction to the delivery stack stored, for example, on a pallet or another type of transport base.The gripper bridges preferably contain leading edge clamping grippers which have gripper fingers which interact with gripper bridges and which are arranged at a distance from one another on a gripper shaft and can be controlled by the latter.

[0207] For the safe transport of the substrates 1 held by the gripper bars, a substrate guide device and, for example, a dryer are provided in the delivery 99. The substrate guide device has substrate guide plates facing the gripper bars, which are equipped with blown air nozzles and extend across the width of the machine. Blow boxes are arranged beneath the substrate guide plate, via which the blown air nozzles are supplied with blown air, so that a supporting air cushion is formed between the substrate guide plate and the substrates 1 transported by the gripper bars. To be able to regulate heating of the substrate guide plate in the area of ​​the dryer, a coolant circuit can be integrated.In order to prevent the substrates 1 from sticking together on the delivery stack, a release agent application device (not further designated), in particular a powder device, preferably combined with a device for sucking off the powder, is preferably provided in the area of ​​the delivery 99.

[0208] A braking device (not further specified) is arranged in front of the delivery stack to decelerate the substrates 1 released by the gripper bars. The braking device can contain rotating suction rings and / or circulating suction belts or be designed as a follow-up gripper system. The substrates 1 decelerated by the braking device engage front stops and are thus deposited in alignment on the delivery stack. The delivery stack is preferably lowered by a stack lifting drive by the amount of the substrate thickness deposited, so that the stack surface always maintains an approximately constant level.

[0209] A further mode of operation of an embodiment, as preferably provided by the Fig. 17, is described below. The substrates 1 to be processed lie as a substrate sheet stack in the feeder 7 and are separated from this substrate sheet stack and fed one after the other either to one or more printing units 6 and printed in these or, if no printing units 6 are provided, directly to the processing unit 46. The substrate sheets 1 are processed in the processing unit 46. For this purpose, the substrate sheets 1 are fed one after the other into a cylinder gap formed between two processing cylinders and punched in such a way that a punched sheet (processed substrate sheet 1) is produced from each substrate sheet 1, which is formed from at least one blank 10 and at least one waste part 9 and a frame enclosing the latter, wherein the blank 10, waste part 9 and frame adhere to one another via material connections that are not completely severed.The processing cylinders can be designed as tool-carrying punching cylinders or embodied by printing cylinders 41 and blanket cylinders 43 of a sheet-fed printing press. The now processed substrate sheets 1 are preferably transferred to the transport cylinder 3 by a sheet transport cylinder at the tangent point A between the transport cylinder 3 and the upstream sheet transport cylinder. The sheet holding system of the sheet transport cylinder releases the processed substrate sheet 1, while the gripper system 17, in particular the suction gripper system 17, of the transport cylinder 3 takes over the processed, in particular cut, substrate sheet 1. The transport cylinder 3 preferably carries a cover 5. The cover 5 has perforations. The perforations are introduced at the locations in the cover 5 where openings 12, 13, in particular first and / or second openings 12, 13, are formed.Preferably, when the openings 12, 13 have passed the tangent point A due to the rotation of the transport cylinder 3 or are located exactly at the tangent point A, a negative pressure is applied to the openings 12, 13 by the first and / or second air supply means 14, 15, which fixes the blanks 10 or only the waste parts 9 or the blanks 10 and the waste parts 9 to the outer surface of the transport cylinder 3 or to the packing 5. As a result of the further rotation of the transport cylinder 3, the waste parts 9, preferably fixed by the negative pressure, reach the tangent point B formed between the transport cylinder 3 and the stripping cylinder 4. At the tangent point B, the raised areas of the packing 5, which is arranged on the stripping cylinder 4, contact the surfaces of the waste parts 9 and press the waste parts 9 into the recesses of the packing 5 fixed on the transport cylinder 3.In this process, the incompletely severed material connections connecting the waste parts 9 to the frame or to the blank 10 are separated, i.e., torn. It goes without saying that the raised areas of the elevator 5 can alternatively be designed as recessed areas. In this case, the corresponding areas of the stripping cylinder 4 are preferably raised. It is crucial that the raised or recessed areas on the transport cylinder 3 and a stripping cylinder 4 associated with it are designed in such a way that the incompletely severed material connections are separated, i.e., torn.

[0210] As a result of the rotation of the transport cylinder 3, the blanks 10 and the waste parts 9 are transported past the tangential point B until they finally reach the transfer point F between the transport cylinder 3 and the further transport system 76. At the transfer point F, the frames with the blanks 10 adhering to them exclusively via incompletely severed material connections are transferred to a stacking device, in particular a delivery 99, more preferably to a respective gripper bridge of the delivery 99, from which they are preferably transported to a stack carrier and stacked.

[0211] When the waste parts 9 reach the transfer point F between the transport cylinder 3 and the further transport system 76, the first and / or second air supply means 14, 15 of the transport cylinder 3 maintain the suction air supply to the first and / or second openings 12, 13. Only when the waste parts 9 reach the release point D is the suction air supply to the first and / or second openings 12, 13 canceled or preferably switched to a blown air supply, so that the waste parts 9 are released or, preferably, actively ejected.

[0212] In connection with the separation processes between transport cylinder 3 and stripping cylinder 4, it proves advantageous in preferred embodiments to remove only selected material connections that have not been completely severed and to specifically maintain others in order to maintain the stability required for further transport of the frame and the panels 10 connected to it. Accordingly, it is preferably provided that the material connections that have not been completely severed between the rear frame part in the transport direction of the frame and the panels 10 are removed between transport cylinder 3 and stripping cylinder 4, and that the material connections that have not been completely severed between the front frame part in the transport direction of the frame and the panels 10 are maintained. Furthermore, the material connections that have not been completely severed between the lateral frame parts in the transport direction of the frame and the panels 10 can also be removed.

[0213] Further preferably, the not completely severed material connections between several blanks 10 are maintained between the transport cylinder 3 and the stripping cylinder 4.

[0214] The method described above can be carried out in particular using one of the described embodiments of the device for treating substrates 1, in particular using the Fig. 17 and in relation to Fig. 17 described device.

[0215] A further preferred embodiment is particularly in Fig. 16 and will be described further below. The embodiment comprises a transport cylinder 3, which in its basic structure is similar to that shown in Fig. 2 shown transport cylinder 3, so that hereby particular reference is made to the Fig. 2 and the associated descriptions and, in addition, to the Fig. 3 to 8 including the associated descriptions. The transport cylinder 3 can be assigned a stripping cylinder 4, which in its basic design is similar to that shown in the Fig. 10 shown stripping cylinder 4, so that hereby the Fig. 10 and the associated description parts.

[0216] The transport cylinder 3 and / or the stripping cylinder 4 preferably have means for fixing a replaceable elevator 5.

[0217] In the case of a preferred embodiment with a transport cylinder 3 without an associated stripping cylinder 4, the means for feeding the replaceable packing 5 are associated with the transport cylinder 3. In the case of a further preferred embodiment with a transport cylinder 3 with an associated stripping cylinder 4, the means for feeding the replaceable packing 5 are associated with the transport cylinder 3 or the stripping cylinder 4, or with both the transport cylinder 3 and the stripping cylinder 4.

[0218] The means for feeding the replaceable packing 5 comprise, when assigned to the transport cylinder 3, a pressing means 60 that can be selectively engaged and disengaged from the transport cylinder 3, in particular pivoted on and off, and, when assigned to the stripping cylinder 4, a pressing means 61 that can be selectively engaged and disengaged from the stripping cylinder 4, in particular pivoted on and off. The pressing means 60, 61 is preferably designed as a roller or cylinder. The roller or cylinder can have an elastic surface, in particular a rubber surface. The roller or cylinder is rotatably mounted and can extend across the entire width of the respective cylinder (transport cylinder 3 or stripping cylinder 4) or only across part of its width. Likewise, the cylinder can be formed by several rollers that are aligned with one another with respect to their rotational axes. The roller or cylinder is freely movable or, in a preferred embodiment, motor-driven.More preferably, the roller or cylinder can also be associated with a motor that drives and / or brakes the roller or cylinder. The cylinder can also be associated with a suitable braking device, for example, in the form of a friction brake.

[0219] The roller or cylinder is preferably mounted on a movable pressure arm 62, 63, to which a drive means 64, 65 is assigned, preferably in the form of a linear drive 64, 65, more preferably in the form of a pneumatic cylinder 64, 65 or an electric linear motor. The pressure arm 62, 63 is pivotable about a pivot point.

[0220] The means for feeding the replaceable packing 5 preferably comprise a guide roller 66, 67 and / or a guide rail 68. Further preferably, the at least one guide roller 66, 67 is associated with a movably mounted guard 70, 71. A sensor detecting the position of the guard 70, 71 can be associated with the guard.

[0221] The means for supplying the exchangeable packing 5 can further comprise a storage 72, 73 capable of accommodating a plurality of packings 5. The storage 72, 73 is designed to store at least one packing 5, while at least one further packing 5 is arranged on the transport cylinder 3 or the stripping cylinder 4, with which the stored packing 5 can be alternately exchanged. The storage 72, 73 can preferably accommodate, in addition to a packing 5 being supplied, also a packing 5 that is being removed or is to be removed. The storage 72, 73 preferably has different storage locations for a packing 5 that is being supplied and a packing 5 that is to be removed.

[0222] The means for feeding the replaceable packing 5 may further comprise a pre-positioning device, in particular positioning pins. The pre-positioning device is preferably associated with the storage device 72, 73.

[0223] To arrange a packing 5 on the transport cylinder 3, the transport cylinder 3 is first rotated into a receiving position intended for receiving the packing 5. The rotation of the transport cylinder 3 can be achieved by means of an individual drive assigned to it or via a gear train that connects the transport cylinder 3 to other cylinders in terms of drive technology and is driven by a main drive. In the receiving position, the means for fixing the front edge of the exchangeable packing 5 are at least approximately opposite the storage 72. The packing 5 to be supplied stands with its lower edge (which corresponds to the front edge when fixed on the transport cylinder 3) on a storage 72 designed as a rail 72, preferably an angled rail. According to a preferred embodiment, positioning means, for example in the form of positioning pins, are assigned to the storage 72, which correspond to positioning recesses in the packing 5.If positioning pins are provided, the positioning recesses in the packing 5 are opposite the positioning pins, and the packing 5 is pre-aligned by the assignment of the positioning recesses to the positioning pins. To feed the packing 5, the lower edge of the packing 5 is released from the rail 72 by pivoting or rotating the rail 72 using a motor, or by manually lifting the front edge of the packing 5 from the rail 72. The pivotally mounted guard 70, which preferably carries a guide roller 66 at its end, is pivoted manually or by a motor, creating an access opening through which the packing 5 can be fed to the means for securing the packing 5.As soon as the front edge of the packing 5 has passed through the access opening cleared by the guard 70 and the guide roller 66, the guard 70 is pivoted back to its original position manually or by a motor, so that the guide roller 66 contacts the packing 5 and thus the packing 5 is guided on its way to the clamping gap formed between the clamping jaw 22 and the stop 24. The packing 5 is preferably fed by the effect of gravity or, alternatively, motor-driven or manually. When the front edge of the packing 5 has reached the clamping gap, the lever 21 is pivoted and thus the front edge of the packing 5 is fixed between the clamping jaw 22 and the stop 24. The transport cylinder 3 is then rotated counterclockwise by a motor. When the front edge of the packing 5 has moved under the pressure roller 60 due to the rotation of the transport cylinder 3, the linear drive 64 is activated.The linear drive 64 pivots the pressure lever 62 until the pressure roller 60 contacts the elevator 5 and presses it against the outer surface of the transport cylinder 3.

[0224] The transport cylinder 3 is then rotated further counterclockwise by a motor and the packing 5 is pressed onto the outer surface of the transport cylinder 3 in the area of ​​influence of the pressure roller 60 until the rear edge of the packing 5 reaches the clamping gap formed between the clamping jaw 47 and the impact pad 48. When the rear edge of the packing 5 is inserted into the clamping gap, the tensioning shaft 50 is rotated and the clamping gap is thus closed. The pressure roller 60 is then pivoted away. If the packing 5 is to be removed from the transport cylinder 3 again, the pressure roller 60 remains pivoted away from the transport cylinder 3. Either the front edge or the rear edge of the packing 5 is released by the transport cylinder 3 and the transport cylinder 3 then rotates so that the packing 5 is conveyed back towards the storage device 72. Finally, the edge of the packing 5, which had been fixed until then, is released.

[0225] The arrangement of a lift 5 on the stripping cylinder 4 is comparable to the arrangement of a lift 5 on the transport cylinder 3, so that reference is preferably made to this unless differences are expressly described.

[0226] To arrange a hoist 5 on the stripping cylinder 4, the stripping cylinder 4 is first rotated into a receiving position intended for receiving the hoist 5. The rotation of the stripping cylinder 4 can be achieved using an individual drive assigned to it or via a gear train that connects the stripping cylinder 4 to other cylinders and is driven by a main drive. Preferably, the stripping cylinder 4 is driven by an individual drive, whereas the transport cylinder 3 is driven via a gear train that connects the transport cylinder 3 to other cylinders and is driven by a main drive.

[0227] In the receiving position, the means for securing the trailing edge of the replaceable packing 5 are at least approximately opposite the storage 73. The packing 5 to be fed stands with its lower edge (which corresponds to the trailing edge when fixed on the stripping cylinder 4) on a storage 73 enclosed by retaining pins. According to a preferred embodiment, the retaining pins are designed as positioning means in the form of positioning pins that correspond to positioning recesses in the packing 5. If positioning pins are provided, the positioning recesses in the packing 5 are opposite the positioning pins, and the packing 5 is pre-aligned by the assignment of the positioning recesses to the positioning pins. To feed the packing 5, the lower edge of the packing 5 is released from the retaining pins by retracting the retaining pins or by manually lifting the trailing edge off the retaining pins.The pivotally mounted guard 71, which preferably carries a guide roller 67 at the end, is pivoted manually or by motor, so that an access opening is created through which the elevator 5 can be fed to the means for fixing the elevator 5.

[0228] As soon as the trailing edge of the packing 5 has passed through the access opening released by the guard 71 and the guide roller 67, the guard 71 is pivoted back to its original position manually or by a motor, so that the guide roller 67 contacts the packing 5 and thus the packing 5 is guided on its way to the clamping gap formed between the clamping jaw 22 and the stop 24. The packing 5 is preferably fed by the effect of gravity or, alternatively, motor-driven or manually. When the trailing edge of the packing 5 has reached the clamping gap, the pneumatic muscle 25 is relaxed and thus the trailing edge of the packing 5 is fixed between the clamping jaw 22 and the stop 24. The stripping cylinder 4 is then rotated clockwise by a motor. When the trailing edge of the packing 5 has moved under the pressure roller 61 due to the rotation of the stripping cylinder 4, the linear drive 65 is activated.The linear drive 65 pivots the pressure lever 63 until the pressure roller 61 contacts the packing 5 and presses it against the outer surface of the stripping cylinder 4. The stripping cylinder 4 is then rotated further clockwise by the motor, and in the area of ​​influence of the pressure roller 61, the packing 5 is pressed onto the outer surface of the stripping cylinder 4 until the front edge of the packing 5 reaches the clamping gap formed between the clamping jaw 47 and the stop 48. When the front edge of the packing 5 is inserted into the clamping gap, the tensioning shaft 50 is rotated, thus closing the clamping gap. The pressure roller 61 is then pivoted away. If the packing 5 is to be removed from the stripping cylinder 4 again, the pressure roller 61 remains pivoted away from the stripping cylinder 4.Either the front edge or the rear edge of the elevator 5 is released by the stripping cylinder 4, and the stripping cylinder 4 then rotates, so that the elevator 5 is conveyed back toward the storage device 73. Finally, the edge of the elevator 5, which was still fixed until then, is released.
