[0001] The invention relates to a device for treating substrates.

[0002] From DE 40 13 116 A1 a method for stacking flat blanks made of cardboard or the like is known, in which the blanks arrive on a first conveyor, are taken over by a second conveyor with the same conveying level and temporarily the same conveying speed and are conveyed in at least one linear shingle stream, are conveyed intermittently at a higher speed on the second conveyor and are thrown over the end of the second conveyor onto a stacking tray located immediately behind it against a stop to form a stack of horizontally flat blanks lying on top of each other.

[0003] From DE 103 56 405 A1, a device for finishing processes, e.g., cutting, punching, embossing, foil transfer, and / or coating, of printed paper, cardboard, cardboard packaging, corrugated board, and plastics is known by means of a rotary process in which the substrate can be inserted in the feed direction between a rotating counter-pressure processing roller and a rotating processing roller and undergoes processing as it passes through tool components acting in the working gap. A discharge conveyor belt for non-shaped substrates, oriented approximately horizontally, is directly downstream of the processing roller. The device is designed exclusively for processing web-shaped substrates.

The counter-pressure processing roller is essentially arranged next to a processing roller, and a discharge conveyor for non-shaped substrates, oriented approximately horizontally, is directly downstream of the processing roller. The processing roller is twice the size of the processing roller and has grippers. The guidance of the substrates on the outer surface of the processing roller, in the areas spaced apart from the grippers, is not variably adjustable for different substrate formats.

[0008] The guiding of the substrates in the areas spaced apart from the gripper on the outer surface of the processing roller is carried out using a large number of mechanically moving individual parts and is susceptible to contamination.

[0009] From DE 10 2004 058 598 A1, a tool part in a device for the finishing processing of printed and / or coated arc-shaped substrates, in particular for e.g. punching by means of a rotational process, is known, in which the substrate can be inserted between two rotating processing rollers and undergoes its processing as it passes through tool parts effective in the working gap, wherein a processing roller has a gripper for the register-compliant transport of the substrate and the tool part profiled as a die has circumferential openings.

[0016] The invention is based on the objective of creating a device for treating substrates that enables the production of products with partial or full-surface film coating.

[0017] This problem is solved by a device designed according to the features of claim 1.

[0018] The advantages achievable with the invention consist in that it enables the processing of pre-assembled film sections available as stacks when coating a substrate with film or creating film windows in the substrate.

[0023] The device for treating substrates 1 with a separation device 2, with which the processed substrate 1 can be separated into at least one waste part 9 and at least one usable part 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.

[0024] According to a further embodiment, the separating device 2 is a component of a substrate processing machine, in particular a sheet-fed processing machine, and is operated inline with the units of the sheet-fed processing machine. A sheet-fed printing press, such as those found, for example, in [reference to a specific machine / company], is particularly suitable as a sheet-fed processing machine. Fig. Figure 1 is shown. 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 shall also apply analogously to other sheet-processing machines and to an embodiment of the device as a stand-alone machine.

[0025] The sheet-fed printing press comprises a feed system for substrates 1, also referred to as a feeder 7. Substrates 1 are understood to be, in particular, sheet-shaped workpieces made of paper, cardboard, corrugated board, 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 and are separated by it and fed to the downstream units of the sheet-fed printing press 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. A rubber blanket cylinder 43, which carries a rubber blanket, is associated with the printing cylinder 41, and this in turn with a plate cylinder 44, which carries 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 manner known per se by the sheet holding systems provided on the printing cylinder 41 and sheet guide cylinder 42, printed in the printing gap formed between the printing cylinder 41 and the blanket cylinder 43, and transferred to the subsequent 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 following or between the printing units 6. The processing units 46 preferably comprise two processing cylinders, one of which, preferably the lower one, has a sheet holding system and the other, preferably the upper one, has a tool carrier. The processing cylinders are arranged relative to each other, forming a cylinder gap. At least one of the processing cylinders carries a tool.In the simplest case, a pair of processing cylinders is formed by the printing cylinder 41 and the blanket cylinder 43 of a printing unit 6. In this case, one printing unit 6 serves as the processing unit 46. The clamping device for the blanket is used to attach the tool to the blanket cylinder 43.

[0026] The processing cylinders can be designed in a variety of ways. According to one embodiment, which is particularly suitable for punching and perforating applications, the upper processing cylinder is designed as a solid magnetic cylinder or a carrier cylinder with magnetic segments for holding magnetic sheets or magnetic plates, and the lower processing cylinder is designed as a surface-hardened cylinder or with a hardened sheet attached to it.

[0027] According to another embodiment, which is particularly suitable for embossing, creasing or grooving applications, the upper processing cylinder is designed as a solid magnetic cylinder or carrier cylinder with magnetic segments for receiving magnetic sheets or magnetic plates, and the lower processing cylinder is designed as a surface-hardened cylinder or with a hardened sheet attached to it or with a sheet made of hard rubber / plastic.

[0028] In all the aforementioned cases, the lower machining cylinder can be equipped with mechanically acting tool carriers or lift carriers, in particular those that engage by positive or non-positive locking mechanisms. The non-positive locking tool carriers or lift carriers are, in particular, designed to engage magnetically.

[0029] According to a further preferred embodiment, the device for processing 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 machining cylinder 97 has a counter-cylinder 98 assigned to it on the side facing away from the first machining cylinder 96, which is in surface contact with the second machining cylinder 97.

[0030] The counter cylinder 98 is associated with the machining cylinder 97 such that, in the event of deflection of the machining cylinder 97, as occurs during machining of substrate arc 1 in the gap between the two machining cylinders 96, 97, the force of the resulting bending force of the second machining cylinder 97 acts on the counter cylinder 98, preferably at or near its center. Geometrically, the centers of the first and second machining cylinders 96, 97 and the counter cylinder 98 preferably lie on an imaginary straight line, or the centers of the second machining cylinder 97 and the counter cylinder 98 lie on a straight line that is inclined at an angle of less than or equal to 10 degrees to a straight line on which the centers of the first and second machining cylinders 96, 97 lie.

[0031] The counter cylinder 98 can have the same diameter as the second machining cylinder 97.

[0032] Similarly, the counter cylinder 98 and the second machining cylinder 97 can have Schmitz rings that are in rolling contact with each other. It is also possible that the surface contact between the counter cylinder 98 and the second machining cylinder 97 is limited to the contact between the Schmitz 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 Schmitz ring adjacent to the respective bearing point.

[0033] The use of Schmitz rings is well-established in printing press construction. On printing presses, Schmitz rings are positioned on the sides of the printing cylinders. The Schmitz ring is designed to prevent Schmitz (a type of bearing slippage). It is made of tempered steel and ground to a high degree of roundness and dimensional accuracy. The Schmitz ring is approximately 1-4 cm wide and rolls either on the base rail or on the Schmitz ring of the counter cylinder. The circumference of the Schmitz ring corresponds exactly to the circumference of the lift or the form, depending on which machine part it is attached to. The Schmitz ring is a positive guidance element on printing presses with a central drive and compensates for minor bearing inaccuracies as well as uneven input and output from the printing press's gear drive.

[0034] In the case of the formation of Schmitz rings, a device for adjusting the pressure between the Schmitz rings by relocating the counter cylinder 98 and / or the second machining cylinder 97 is advantageously provided.

[0035] The counter cylinder 98 is preferably associated with a device for fixing a lift. This enables the lift to be arranged on the counter cylinder 98 to ensure that it maintains surface contact, particularly rolling contact, with the second machining cylinder 97, even when a tool of varying thickness is arranged on it, or with the tool arranged on its surface. Preferably, the counter cylinder 98 is also associated with a device for clamping the lift in the circumferential direction of the counter cylinder 98, which can form a single unit with the device for fixing a lift.

[0036] In particular, for the use of a profiled lift, for example in the form of a die, it proves advantageous if the counter cylinder 98 has a register system for positioning a lift on the counter cylinder 98.

[0037] According to a further preferred embodiment, which facilitates the exchange of tool parts, the device for processing substrates 1 comprises a processing unit 46 with two cooperating processing cylinders 96, 97, between which the substrate 1 can be inserted. As the substrate 1 passes through the cylinder gap between the processing cylinders 96, 97, it is processed by tool parts from the group consisting of cutting tools, punching tools, grooving tools, perforating tools, or slotting tools. At least one of the processing cylinders 96, 97 is designed as a magnetic cylinder. A peeling device for removing at least one tool part is associated with the processing cylinder 96, 97 designed as a magnetic cylinder.

[0038] According to a further preferred embodiment, which facilitates the exchange of tool parts, the device for treating substrates 1 comprises a separation unit 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 lift 5 into at least one waste part 9 and at least one usable portion 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 lift 5 is associated with 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 positioned and / or disengaged from the cylinder to which it is assigned and which is designed to support a lift 5, in particular the processing cylinder 96, 97, the transport cylinder 3, or the stripping cylinder 4. The peeling device 103 has a peeling edge 104. When the peeling device 103 is positioned against 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, the transport cylinder 3, or the stripping cylinder 4. Furthermore, it is advantageous if the peeling device 103 forms a single 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. The peeling device 103 acts to protect the operator from injury caused by a rotating cylinder or to avoid or reduce noise or dust emissions. It is also possible to assign the peeling device 103 to parts of the plate changing unit or the elevator changing device. If the peeling device 103 forms a unit with a guard 70, 71, the unit can function as a peeling device 103 in one position and as a guard 70, 71 in another.

[0039] Preferably, the peeling device 103 has a holding element for fixing the tool parts or the at least one elevator 5. The holding element can be pneumatically or magnetically actuated or designed in another suitable manner, e.g. in the form of a step or latch.

[0040] To ensure that the peeling device 103 engages an edge of the tool part or the at least one lift 5, the tool part or the at least one lift 5 can be manually lifted. According to an advantageous alternative, an ejector is provided for this purpose, which is associated with 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 lift 5 from the surface of the processing cylinder 96, 97 or the transport cylinder 3 or the stripping cylinder 4.

[0041] Preferably, a drive acting on the processing cylinder 96, 97 and / or the transport cylinder 3 and / or the stripping cylinder 4 is provided, with which a drive control system interacts. The drive control system 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 where one end of a tool part or of the at least one lift 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 system can cause the processing cylinder 96, 97 and / or the transport cylinder 3 and / or the stripping cylinder 4 to be rotated such that the other end of the tool part or of the at least one lift 5 is opposite the peeling device 103 and / or is located within the effective range of the peeling device 103.During rotation, the peeling device 103 peels the tool part or the at least one lift 5 from the respective cylinder surface. Between the positioning and rotation of the machining 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 lift 5 from the surface of the machining cylinder 96, 97 or the transport cylinder 3 or the stripping cylinder 4.

[0042] In the aforementioned context, a magnetic cylinder is understood to mean all types of cylinders or drums that exert a magnetic force on adjacent ferromagnetic elements in the region 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, a cylinder with embedded magnetic segments, or as a carrier cylinder for magnetic segments or magnetic sheets arranged on it; the same applies analogously to the drum design.

[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, comprises, in addition to preferably printing units 6 and processing units 46, further units which may be arranged individually or in groups in any sequence. Thus, one or more coating units 88.2 and / or one or more separating units 2.2 and / or one or more window application units 85 or a foil application unit 85 and / or one or more die-cutting units may be arranged alternatively or in addition to the aforementioned units.

[0046] A window application unit 85 or film application unit 85 can be designed in various configurations. In a first configuration, the film is in the form of film sections. The first configuration preferably comprises a transport cylinder 3.1 for transporting arc-shaped substrates 1, an arc conveying device, e.g., in the form of an arc-guiding cylinder, which interacts with the transport cylinder 3.1, a film feeder 86 which has means for guiding film sections, and a coating device 88 for supplying an adhesion promoter to the substrate 1 or to a respective film section.

[0047] The film feeder 86 can have a storage unit 93 for receiving a stack formed from film sections and a singulation device which singulates film sections from the stack formed from film sections and accelerates them to the circumferential speed of the transport cylinder 3.1.

[0048] Preferably the film feed 86 comprises a feed cylinder 84 which forms a press gap with the transport cylinder 3.1.

[0049] The singulation device can include a transport element 94 for singulating the film sections from the top or bottom of the stack formed from the film sections. A transport element 94 is preferably provided for feeding the film sections to the press gap formed between the feed cylinder 84 and the transport cylinder 3.1. The transport element 94 can include one or more elements from the group consisting of suction belts and / or suction rollers and / or suction cups. The transport mechanism for the elements provided as transport elements 94 preferably consists of a force resulting from an applied vacuum. Alternatively or additionally, frictional engagement can also serve as the transport mechanism. If a suction cup is provided as the transport element 94, it can, for example, be designed as a combined suction cup and have one or more trailing suction cups that interact with one or more lifting suction cups.

[0050] The transport element 94 can be designed for the direct feeding of a single film section to the press gap or feed cylinder 84. In this context, direct feeding means feeding without transfer, i.e., intermediate transfer to another transport element 94.

[0051] 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 for the suction air supply can be designed depending on the angular position of the respective supplied openings.

[0052] The coating device 88 can be assigned to the transport cylinder 3.1 or a feed cylinder 84.

[0053] 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.

[0054] The coating device 88 can be designed as a coating unit and / or include an application roller and / or an inkjet head. Preferably, the coating device 88 is configured 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. In the case of a coating device 88 with an application roller, a printing plate, in particular a coating plate, especially a flexographic plate, can be provided for addressable, partial coating.

[0055] In a second preferred design of a window application unit 85 or foil application unit 85, the foil is in the form of a foil web 87.

[0056] The second embodiment preferably comprises a transport cylinder 3.1 for transporting sheet-shaped substrates 1, a sheet conveying device that interacts with the transport cylinder 3.1, and a film feeder 86 that has means for guiding a film web 87. The second embodiment preferably includes 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.

According to one embodiment, the air supply means for the suction air supply can be designed depending on the angular position of the respective supplied openings.

[0058] 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.

[0059] The coating device 88 can be designed as a coating unit and / or include an application roller and / or an inkjet head. Preferably, the coating device 88 is configured 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.

[0063] Another window application unit 85 or foil application unit 85 of the second design is Fig. 35 or Fig. 42. It differs from the window application unit 85 or foil application unit 85 according to Fig. 33 or Fig. 40 by the fact that the film feed 86 includes an unwinding device 91 but no winding device.

[0094] For all described designs with a foil application unit or window application unit 85, it is advantageous to arrange a turning device directly or indirectly before 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 tear-outs resulting from cutting or punching in substrate 1 would occur on the inside of the envelopes, where they are less noticeable than on the outside.

[0095] The following describes a preferred method for treating arc-shaped substrates 1, which is comparable to one of the embodiments according to the Fig. 33, Fig. 34, Fig. 35, Fig. 36, Fig. 37, Fig. 38, Fig. 39, Fig. 40, Fig. 41, Fig. 42, Fig. 43, Fig. 44, Fig. 45 to Fig. 46 can be carried out.

[0096] The procedure is as follows.

[0097] In a punching step, window-shaped areas are punched into the substrates 1, preserving the material bonds. In a separating step, which preferably follows directly after the punching step, the window-shaped areas are broken out of the substrates 1, severing the material bonds and forming window-shaped recesses in the substrates 1. In a coating step, which preferably follows directly after the separating step, the substrates 1 are coated with adhesive in the area adjacent to the window-shaped recesses. In a window application step, sections of film, whose dimensions exceed those of the window-shaped recesses, are positioned over the window-shaped recesses and fixed with the adhesive.Preferably, in the die-cutting process step, blanks 10 are die-cut into the substrates 1, each of which has at least one window-shaped area, while maintaining further material connections between the blanks 10 and between the blanks 10 and waste parts 9. In the case of window envelope production, such a blank 10 would represent an unfolded envelope. After the window is applied, the substrates 1 are either placed directly onto a stack or a conveyor belt 29, 30. Alternatively, before placement, the remaining 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 separation process. It is also possible to print on the substrates 1 before the die-cutting process step.The described process steps are preferably carried out in successive units of a sheet-processing machine, in particular a rotary printing press.

[0098] Another description relates to a method for treating arc-shaped substrates 1.

[0099] The procedure is as follows.

[0100] Each substrate sheet 1 is separated from a stack of substrate sheets 1 by a feeder 7, then embossed and / or dried in a first processing unit 46, then scored or die-cut and / or punched in a second processing unit 46, and subsequently die-cut and / or punched and / or perforated and / or embossed and / or scored in a third processing unit 46. Preferably, each substrate sheet 1 is printed in one or more printing units 6 and / or varnished in one or more coating units between separation in the feeder 7 and processing in the first processing unit 46. Alternatively or additionally, printing and / or varnishing in at least one printing or coating unit can also take place between processing in two of the processing units 46 and / or after processing in the last processing unit 46.After separation, the arc-shaped substrates 1 or utility 10 are preferably placed in a display 99 or on a conveyor belt 29, 30 in a stack or as a sequence, scaly or unscathed.

[0101] Cutting, in this context, refers specifically to the complete mechanical separation of an unstamped material by pressure, primarily involving shear stresses. The cutting process can be carried out using the knife-cutting, shear-cutting, or burst-cutting principles.

[0102] Punching refers specifically to the process of dividing materials along a dividing line that deviates from a straight line. Preferably, this refers to the production of cutouts and blanks with closed boundary lines. In some cases, however, open cuts are also achieved through punching, e.g., rounding corners and register punching.

[0103] Embossing refers to the processing of materials by applying pressure with appropriate tools, whereby the material is shaped and / or deformed in a relief-like manner.

[0104] Grooving refers to the processing of materials by applying pressure with appropriate tools, creating elongated, narrow indentations in the surface of the material.

[0105] Perforation is the process of machining materials by applying pressure with appropriate tools, creating a large number of holes, mostly arranged in a line, within the material. The distances between the holes are preferably equal.

[0106] For carrying out the individual process steps of the described processes, a separate unit is preferably provided for each step, which can be combined with other units in any sequence to implement modified production sequences. For this purpose, the units preferably have independent frame walls. In particular, the stamping step or the stamping and cutting steps are carried out with a stamping unit, the cutting step with a cutting unit 2.2, the coating step with a coating unit 88.2, and the window application step or the coating and window application steps with a window application unit 85. Each of the aforementioned units, with the exception of the last unit, transfers the substrate 1 to the following unit after carrying out at least one process step.

[0107] Depending on the specific machine configuration implemented, with or without a film application unit or window application unit 85, after passing through various processing stages, either substrate sheets 1 (panels 10 connected to each other via residual webs, with or without frames) are available, which are placed in stacks in a delivery unit 99, or die-cut panels 10, which are preferably conveyed out of the machine on a conveyor belt 30. These panels 10 are preferably divided into panel streams that have a lateral distance from each other. For this purpose, several pairs of rollers are arranged downstream of the conveyor belt 30, with each pair of rollers being arranged diverging from the other pairs, i.e., with a different lateral angle. The roller pairs each form a roller gap and rotate at a circumferential speed that is greater than the speed of the conveyor belt 30.The adjacent and consecutively arranged panels 10 are conveyed by the conveyor belt 30 into their respective roll gaps. In the roll gap, the individual panels 10 are then picked up, accelerated to the peripheral speed of the rolls, and spaced apart according to the orientation of the roll pair. The roll pairs can be moved transversely to their transport direction 74 for positioning onto the panels 10. A conveyor belt is arranged downstream of the roll pairs, which picks up the panels 10, now spaced laterally apart, and transports them away. This downstream conveyor belt preferably runs at a speed lower than the peripheral speed of the roll pairs.

[0108] A device for handling, in particular depositing, substrates 1, in particular utility 10, can be connected to the downstream conveyor belt, which is described below, in particular with regard to the Fig. 18 and Fig. The device is described in section 19. It comprises a circulating conveyor belt 29, 30 that conveys the substrates 1, in particular panels 10, in at least one lane, preferably as a shingle stream, against at least one stop 77 for depositing the substrates 1 onto a stacking carrier 78. The stacking carrier 78 can be a standard pallet or a system pallet, such as those used in logistics systems of printing companies or in the finishing sector. A transport device 79 is provided for handling, in particular repositioning, the stacking carrier 78. This device allows the stacking carrier 78 to be repositioned under the at least one stop 77 and / or the conveyor belt 29, 30 in such a way that the substrate sheets 1 or panels 10 conveyed by the conveyor belt 29, 30 are deposited onto the stacking carrier 78. The transport device 79 is designed for vertical and horizontal repositioning of the stacking carrier 78.A device for creating a gap in the shingle stream 83 is associated with the conveyor belt 29, 30. This device is preferably designed as a roller 83 or cylinder. The roller 83 or cylinder is arranged to be displaceable, preferably by being mounted on levers at its ends. If a gap in the shingle stream needs to be created, for example, because the stacking carrier 78 needs to be moved or replaced, the roller 83 or cylinder is displaced or pivoted until it is in surface contact with the conveyor belt 29, 30. If the conveyor belt 29, 30 continues to convey substrate sheets 1 as a result of its movement, these are accumulated against the roller 83 or cylinder. The roller 83 or cylinder can be mounted in a fixed or rotatable manner and, in the latter case, is preferably braked.

[0109] The transport device 79 is designed to move the stacking carrier 78 into one or more positions in which the stacking carrier 78 and the at least one stop 77 and / or the stacking carrier 78 and the conveyor belt 29, 30 overlap. Preferably, several stops 77 are arranged side by side in groups transverse to the transport direction 74 of the substrate sheet 1 or the panel 10 on the conveyor belt 29, 30. More preferably, each group of stops 77 has either two side stops or two side stops and one rear stop. Each group of stops preferably forms a kind of pocket, which is aligned with the flow(s) of substrate sheet 1 or panel 10 onto the conveyor belt 29, 30 by laterally positioning the stops 77.

[0110] The stops 77 are vertically movable. One or more drives are provided 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 stacking carrier 78. The transport device 79 is preferably designed for displacement of the stacking carrier 78 in and against the transport direction 74 of the conveyor belt 29, 30. More preferably, the transport device 79 is designed for displacement of the stacking carrier 78 in the transport direction 74 of the conveyor belt 29, 30 depending on the extent of the substrates 1 or panels 10 in the transport direction 74 of the conveyor belt 29, 30.The transport device 79 is preferably designed to realize a movement cycle comprising 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.

[0111] Furthermore, a feeding device 80 can be configured with which at least one separating element 81 can be positioned onto the substrates 1 supported by the stack carrier 78. The feeding device 80 comprises a singulation device that separates the separating elements 81 from a stack 82 formed from several separating elements 81. The separating elements 81 are preferably arc-shaped materials that can be inserted between stacks of substrates for spatial separation. The feeding device 80 can be formed by a horizontally movable frame, the underside of which is equipped with vertically movable suction cups or other suitable fixing elements. The feeding device 80 can also be configured with rigid suction cups or other suitable fixing elements, provided that the frame allows vertical movement for lifting a respective separating element 81.

[0112] Preferred movement sequences, which the stacking carrier 78 realizes through the action of the transport direction 74, are described below, particularly with regard to the Fig. 20, Fig. 21, Fig. 22, Fig. 23, Fig. 24, Fig. 25, Fig. 26, Fig. 27, Fig. 28, Fig. 29, Fig. 30, Fig. 31 to Fig. 32 examples will be described.

[0113] First, the stacking carrier 78 is positioned by the transport device 79 with respect to the conveyor belt 29, 30 such that, in its vertical position, it has the smallest possible distance to the underside of the conveyor belt. In its horizontal position, it is positioned such that the modules 10 or substrate sheets 1 conveyed by the conveyor belt 29, 30 are deposited onto the stacking carrier 78. With the conveyor belt 29, 30 circulating, the substrate sheets 1 or modules 10 are then conveyed onto the stacking carrier 78 and aligned laterally and preferably also in the transport direction 74 by the stops 77. Subsequently, the stack of substrate sheets 1 or modules 10 grows, as shown in Fig. Figure 21 shows that the stacking carrier 78 is preferably lowered. The stops 77 can be lowered synchronously with the lowering movement of the stacking carrier 78. Alternatively, the stacking carrier 78 can be positioned from the outset at such a vertical distance to the conveyor belt 29, 30 that it is able to accommodate a sufficient quantity of substrate sheets 1 or panels 10 without vertical movement. Fig. In section 21, only one stack is visible. Several other adjacent stacks can be formed simultaneously. When the stack of substrate sheets 1 or panels 10 reaches a sufficient height, the stops 77, if they were moved with the stacking carrier 78, are moved vertically back to their initial position. The stacking carrier 78 is moved vertically to its initial position and horizontally by a distance equal to the length of the substrate sheets 1 to be laid down plus a distance value. The timing of the movement of the stacking carrier 78 and the stops 77 is irrelevant, provided collisions are avoided. Preferably, the movement occurs synchronously. During the movement of the stacking carrier 78, the device for creating a gap in the sheath flow 83 is activated, so that no substrate sheets 1 or panels 10 are fed to the stacking carrier 78 during this time.After deactivating the device for forming a gap in the shingle stream 83, the next stack of substrate arc 1 or panel 10 can be formed on the stack support 78 (. Fig. 24).

[0114] The processes are then repeated as described for the formation of the first stack from substrate sheet 1 or utility 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, next to each other ( Fig. 25).

[0115] At this point in the process, the feeding device 80 can be used. This detects 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 panels 10 formed on the stack carrier 78, where it is released and placed on the respective uppermost substrate sheet 1 or panel 10 ( Fig. 26). The surface of the separating arc 81 subsequently replaces the surface of the stacking support 78 and thus forms the new stacking plane.

[0116] In a next step, a single or multiple stacks of substrate sheets 1 or panels 10 are formed on the new stacking level. For this purpose, the stacking carrier 78 is positioned vertically by the transport device 79 such that the new stacking level lies below the release level of the conveyor belt 29, 30. Horizontally, the positioning is such that panels 10 or substrate sheets 1 conveyed by the conveyor belt 29, 30 are deposited on the separating element 81. Fig. 28)

[0117] On a circulating conveyor belt 29, 30, substrate sheets 1 or panels 10 are then conveyed onto the separating element 81 and aligned laterally by the stops 77 and preferably also in the transport direction 74. Subsequently, the stack of substrate sheets 1 or panels 10 grows as described in Fig. 29 shown.

[0118] The stacking carrier 78 is preferably lowered. The stops 77 can be lowered synchronously with the lowering movement of the stacking carrier 78. Alternatively, the stacking carrier 78 can be positioned from the outset at a vertical distance from the conveyor belt 29, 30 such that it can accommodate a sufficient quantity of substrate sheets 1 or panels 10 without vertical movement. When the stack of substrate sheets 1 or panels 10 has reached a sufficient height, the stops 77, if they were moved with the stacking carrier 78, are moved vertically back to their initial position. The stacking carrier 78 is moved vertically to the position it held on the separating element 81 at the beginning of the formation of the first stack and horizontally by a distance corresponding to the length of the substrate sheets 1 to be laid down plus a distance value.

[0119] During the relocation of the stack carrier 78, the device for forming a gap in the shingle stream 83 is activated, so that no substrate sheets 1 or panels 10 are supplied to the stack carrier 78 during this time. After the device for forming a gap in the shingle stream 83 is deactivated, the next stack of substrate sheets 1 or panels 10 can be formed on the separating element 81 ( Fig. 31).

[0120] Once a sufficient number of stacks of substrate sheet 1 or utility 10 have been formed on the stacking carrier 78, the loaded stacking carrier 78 is removed and replaced by a new receiving stacking carrier 78.

[0121] The sequence of units in a sheet-fed printing press is determined by technological requirements. Preferably, one or more finishing 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, die-cutting tools, creasing tools, perforating tools, or grooving tools. Likewise, one or more finishing units 46 can be positioned upstream of one or more printing units 6. Alternatively, one or more finishing units 46 can be interposed between one or more printing units 6. Preferably, the sheet-fed printing press also includes one or more coating units, which are preferably located downstream of the printing units 6 or connected to the finishing units 46.

[0122] A substrate processing machine, in particular a sheet processing machine, which is not a printing machine, can be similar in its construction to the described sheet printing machine, reduced by the number of printing units 6.

[0123] The separating device 2 is formed following 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 version of the transport cylinder 3. The invention is described below using a single-sized system as an example. This description also applies analogously to the double-sized or multiple-sized systems. A sheet holding system for fixing the leading edges of the sheet-shaped substrate 1, in particular a gripper system, is formed in the area of ​​the outer surface of the transport cylinder 3 (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 and is supplied by air.The suction gripper system 17 is designed to generate a suction area whose axial extent along the transport cylinder 3 is a multiple of its circumferential extent. The circumferential extent of the suction area of ​​the suction gripper system 17 along the transport cylinder 3 is preferably 15 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. Advantageously, the axial extent of the suction area along the transport cylinder 3 is adjustable. For this purpose, adjusting means 28, particularly in the form of shut-off valves, can be provided in the suction air supply path for the suction openings located further out from the center of the transport cylinder 3. The adjustability of the suction area's extent minimizes suction air consumption.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 lift 5. The fixing means are preferably designed as clamping grippers. Each lift 5 can be fixed at its rear edge and front edge using these grippers. The means for fixing the front edge of the lift 5 are preferably formed by the front edge clamping element 22 (also referred to as the clamping jaw) and the further clamping element 24 (also referred to as the stop), which interacts correlatively with it 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 pivotably mounted on the base body of the transport cylinder 3 about a pivot point 34.The lever 21 is tensioned by a force storage element 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 at one end on the lever 21 and at its other end on the head of a screw screwed into the base body of the transport cylinder 3. Fig. Figure 3 shows the clamping gripper's front edge with the fixed front edge of the elevator 5, i.e., in the closed state. Fig. Figure 4 shows the clamping gripper's front edge with the front edge of the elevator 5 released, i.e., in the open state. The opening of the clamping gripper's front edge is effected against the force of the spring 23. The force required to open the clamping gripper's front edge is preferably applied by an actuating element 23, which may 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 at a fixed point of the transport cylinder 3. Under the force of the actuating element 23, which may in particular be designed as a pneumatic muscle 23, the further lever 33 can be pivoted about the aforementioned fixed point. If designed as a pneumatic muscle 23, it is pressurized with compressed air, under the effect of which it expands, thereby pivoting the further lever 33.The pivoting movement of the second lever 33 is limited by a wall formed on the transport cylinder 3. The second lever 33 acts on a ball 35, which is formed between the second lever 33 and the lever 21, and displaces it. With the displacement of the ball 35, 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 off, the force of the energy storage device 23, in particular the spring 23, displaces the lever 21, the ball 35 and the second lever 33 back towards their initial position, until the movement is limited by the clamping element front edge 22 striking the second clamping element front edge 24 or the lift 5.The rear edge of the elevator 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 element is applied by a rotatable clamping shaft 50, which acts on the rear edge clamping element 47 via a toggle lever 51. To clamp the elevator 5, at least one of the clamping elements, i.e., either the front edge clamping element or the rear edge clamping element, can be displaced in the circumferential direction of the transport cylinder. Fig. 3 and Fig. 4 The rear edge of the clamping gripper is displaceable. In particular, the rear edge of the clamping gripper is mounted on a slide that is displaceable in the circumferential direction of the transport cylinder 3. The slide 49 preferably carries, in addition to the rear edge of the clamping gripper, the clamping shaft 50 and the toggle lever 51. To clamp the elevator 5, it is first fixed at both ends by the front edge and rear edge of the clamping gripper. Subsequently, the slide 49 is moved clockwise, which is effected by a further actuating element 52, which may also be designed as a pneumatic muscle. Regardless of the design of the means for fixing the elevator 5, these preferably have positioning pins or are preferably associated with positioning elements. The positioning pins or positioning elements may, in particular, be directly associated with the further front edge clamping element 22.

[0124] 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 are provided for supplying the first openings 12 with air and second air supply means 15 for supplying the second openings 13 with air. In the following context, "air" is understood to mean all forms of system air, i.e., in particular, blown air or suction air, which are suitable, in particular, to exert physical effects such as force and which can be characterized by at least one of the parameters static pressure, dynamic pressure, or volume flow. The chemical composition of the air or its moisture content is not relevant in this context.Such air is generated in a manner known per se using compressors, vacuum pumps, suction pumps, or similar components. The aforementioned air generators can be comprised of the first and second air supply means 14, 15 of the transport cylinder and, in particular, together with all means that supply the air to the openings 12, 14 and / or control the supply, forming the air supply means 14, 15.

[0125] The first and second openings 12, 13 are preferably independently supplied with air. Preferably, the air supply to either the first or the second openings 14, 15, or to both openings 14, 15, is switchable. Switchability in this sense refers in particular to switching between suction air and blowing air, and it is irrelevant which type of air supply is being switched from to which.

[0126] The first and second openings 12, 13 are formed in the outer surface of the transport cylinder 3. Preferably, the first and second openings 12, 13 are arranged alternately in the circumferential direction or in the axial direction of the transport cylinder 3. The first and / or the second openings 12, 13 are preferably groove-shaped or perforated. The arrangement of the first and second openings 12, 13 in the outer surface of the transport cylinder 3 preferably results in a fine mesh of elements with which any openings formed in the elevator 5 can be supplied with air. The arrangement of the openings in the elevator 5 corresponds to the arrangement of the waste section(s) 9 on the one hand and the utility 10 on the other.For example, in the area of ​​the first openings 12, which are formed in the area of ​​the load, openings can be formed in the elevator 5, while all second openings 13, which are formed in the area of ​​the load 10, do not correspond to openings in the elevator 5. The same applies analogously to the area of ​​waste parts 9, whereby the second openings 13 correspond to openings in the elevator 5, while the first openings 12 are covered by closed areas of the elevator 5. Through these measures, loads 10 and waste parts 9 can be treated differently, or rather, fixed to the outer surface of the transport cylinder 3 or its elevator 5.

[0127] The details of the air supply to the first and second openings 12, 13 are described in particular in the Fig. 5, Fig. 6 and Fig. Figure 7 shows 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 or associated with the end face of the transport cylinder 3. Preferably, two rotary valves or two rotary inlets are formed on opposite end faces of the transport cylinder 3. In the case described in the Fig. 5, Fig. 6 and Fig. In the example shown in Figure 7, the rotary valve or the at least one rotary insertion comprises a disk 18, which is associated with one of the end faces of the transport cylinder 3. Several groove-shaped recesses 19, 56, 57 are formed in the disk 18, which preferably extend in a circular segment shape, coaxial with the axis of rotation 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 a circular segment shape with different radii, coaxial with the axis of rotation 16 of the transport cylinder 3.Each of the recesses 19, 56, and 57 need not be continuous in the circumferential direction of the disk 18 but can instead be perforated, so that several recesses 19, 56, and 57 are arranged one behind the other on the same radius when viewed in the circumferential direction of the disk 18. The recesses 19, 56, and 57 correspond, with respect to their distance (radius) to the axis of rotation 16 of the transport cylinder 3, to openings 58 formed in the end face of the transport cylinder 3. Each of the openings 58 in the end face of the transport cylinder 3 communicates via further lines either with one or a portion of the first openings 12, or with one or a portion 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 of the respective recess 19, 56, and 57 is opposite the angular position of the transport cylinder 3. In the case of... Fig. In the embodiment shown in Figure 2, the recesses 57 closest to the axis of rotation 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.

[0128] The disk 18 is stationary relative to the transport cylinder 3, which rotates about the axis of rotation 16 during operation. The extension of the recesses 19, 56 and 57 in the circumferential direction of the transport cylinder 3 defines areas of suction or blowing air, which are formed on the outer surface of the transport cylinder 3 with respect to the angle of rotation.

[0129] In addition to these effects, the areas supplied by suction or blowing air can also be determined by the type of air supply and its activation or deactivation. For example, the area supplied by the same air supply means 12 or 13 according to the recesses 19, 56 can be shortened by angularly switching off the air supply. Likewise, an area supplied by the same air supply means 12 or 13 according to the recesses 19, 56 can be subdivided 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 serves to fix the product 10 or waste parts 9, and the blowing area serves to eject them.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.

[0130] In a preferred embodiment, the first and / or the second air supply means 14, 15 are configured to switch off the suction air supply or switch between suction air supply and blowing air supply depending on the angular position of the respective supplied openings 12, 13. Preferably, the first air supply means 14 switch off the air supply to the first openings 12 or switch from suction air supply to blowing 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 switch off the air supply to the second openings 13 or switch from suction air supply to blowing 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.

[0131] 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 articulated.

[0132] To relocate the areas of suction or blowing air, which are formed on the outer surface of the transport cylinder 3 with respect to the angle of rotation, adjusting devices for rotating the disc 18 can be provided.

[0133] To facilitate assembly, the disc 18 preferably has a recess that allows radial displacement of the disc 18 for the purpose of replacement.

[0134] Instead of one disk 18, several disks 18 can also be provided. In the case of several disks 18, the recesses 57 for supplying the suction gripper system 17 are formed in one of the disks 18, and the recesses 19 and 56 for supplying the first and second openings 12, 13 are formed in the other disk 18.

[0135] The details of the supply of the suction gripper system 17 are in a preferred variant in Fig. Figure 8 shows the following embodiment. 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.

[0136] Alternatively, the disk 18 can also have exclusively a groove-shaped recess 57, which preferably extends in a circular segment shape, coaxial to the axis of rotation 16 of the transport cylinder 3. In this embodiment as well, the recess 57 is supplied with air by a third supply nozzle 55. The recess 57 is formed on the side of the disk 18 facing the transport cylinder 3. The recess 57 is preferably continuous or interrupted in the circumferential direction of the disk 18, so that several recesses 57 or sections of the recess 57 are formed one behind the other on the same radius when viewed in the circumferential direction of the disk 18. The recess 57 corresponds with respect to its distance (radius) from the axis of rotation 16 of the transport cylinder 3 to one or more openings 58 formed in the end face of the transport cylinder 3. The opening 58 or each opening 58 communicates with the suction gripper system 17 via further lines.This only applies, of course, 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., in which the suction gripper system 17 exerts a holding effect, is determined by the extent and position of the recesses 57.

[0137] 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 activate and deactivate the suction air applied to the suction gripper system 17 in a sufficiently rapid, cyclical manner.

[0138] The suction gripper system 17 is formed in the area of ​​the outer surface of the transport cylinder 3. Preferably, the suction gripper system 17 is associated with the means for fixing the elevator 5. In particular, the suction gripper system 17 can be mounted on the means for fixing the elevator 5. Preferably, the means for fixing the elevator 5, and thus also the suction gripper system 17, is movably mounted, in particular pivotably mounted. The suction gripper system 17 can, in particular, be associated with the front edge 22 of the clamping element. It is also advantageous to arrange the suction gripper system 17 together with the clamping element 22 on the lever 21.

[0139] In a preferred embodiment, a stripping cylinder 4 is arranged adjacent to the transport cylinder 3. The stripping cylinder 4, like the transport cylinder 3, is rotatably mounted. The stripping cylinder 4 serves to strip waste pieces 9 or usable material 10. Preferably, the stripping cylinder 4 has third openings 32. Third air supply means are provided to supply the third openings 32 with air.

[0140] The breakout cylinder 4, like the transport cylinder 3, can be configured as either a double-sized or single-sized cylinder. In the case of a double-sized version of the breakout cylinder 4, its circumference or diameter corresponds to that of a double-sized transport cylinder 3. Preferably, the breakout cylinder 4 is configured as a single-sized cylinder. In its construction, the breakout cylinder 4 preferably resembles the transport cylinder 3 in many features, so that the description of the characteristics of the breakout cylinder 4 refers to the descriptions of the characteristics of the transport cylinder 3. This applies in particular to all assemblies of the transport cylinder 3 or the breakout cylinder 4 for which no structural differences or absences are explicitly indicated. The characteristics of the breakout cylinder 4 are described below using a single-sized system as an example.This description also applies analogously to the double-sized or multiple-sized system. Unlike the transport cylinder 3, the stripping cylinder 4 does not include an arc-holding system for fixing the leading edges of the arc-shaped substrate 1.

[0141] Like the transport cylinder 3, the breakout cylinder 4 preferably has means for fixing an interchangeable lift 5. The fixing means are preferably designed as clamping grippers. These grippers allow each lift 5 to be fixed at its rear edge and front edge. The means for fixing the front edge of the lift 5 are preferably formed by the front edge clamping element 22 and the further clamping element 24, which interacts with it to form a clamping gap. The front edge clamping element 22 is mounted on the base body of the breakout cylinder 4. The further clamping element 24 can, in particular, be designed 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, bearing 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 extent changes in the direction of the clamping element's leading edge 22. By applying overpressure, e.g., in the form of compressed air, to the actuating element 25, the gap formed between the leading edge of the clamping element 22 and the further clamping element 24 can be increased, and when the overpressure is released at the actuating element 25, it can be decreased, which corresponds to clamping the elevator 5. Fig. Figure 10 shows the clamping gripper of the breakout cylinder 4 front edge with the fixed front edge of the elevator 5, i.e. in the closed state.

[0142] The trailing edge of the elevator 5 can be fixed between a trailing edge clamping element 47 and another trailing edge clamping element 48, which together form a further clamping gap. The force required to close the trailing edge clamping gripper is applied by a rotatable clamping shaft 50, which acts on the trailing edge clamping element 47 via a toggle lever 51.

[0143] To tension the elevator 5, at least one of the clamping grippers, i.e., the clamping gripper's front edge or the clamping gripper's rear edge, can be displaced in the circumferential direction of the breakout cylinder 4. In the Fig. 10 The rear edge of the clamping gripper is displaceable. In particular, the rear edge of the clamping gripper is mounted on a slide 49 that is displaceable in the circumferential direction of the breakout cylinder 4. The slide 49 preferably also carries the clamping shaft 50 and the toggle lever 51 in addition to the rear edge of the clamping gripper. To tension the elevator 5, it is first fixed at both ends by the front edge of the clamping gripper and by the rear edge of the clamping gripper. Subsequently, the slide 49 is moved counterclockwise, which is effected by a further actuating element 52, which can also be designed as a pneumatic muscle.

[0144] Regardless of the design of the means for fixing the elevator 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.

[0145] It goes without saying that the described elements for fixing the front edge and the elements for fixing the rear edge can also be designed in other ways. As an alternative to the design of force-fit elements, it is also advantageous if the elements for fixing the front edge and / or the elements for fixing the rear edge are designed for form-fit fixing of 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.

[0146] The clamping gripper front edge or the clamping gripper rear edge are preferably mounted in a channel of the breakout cylinder 4, which may be spanned by a channel cover.

[0147] The breakout 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, i.e., in particular, blown air or suction air, which are suitable, in particular, to exert physical effects such as force 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, vacuum pumps, suction pumps, or similar components.

[0148] The third openings 32 can be supplied with suction air. Preferably, the air supply is switchable. Switchability in this sense refers in particular to switching between suction air and blown air, regardless of the type of air supply being switched from one to the other. The third openings 32 are formed in the outer surface of the breakout cylinder 4. Preferably, the third openings 32 are groove-shaped or perforated. The arrangement of the third openings 32 in the outer surface of the breakout cylinder 4 preferably results in a fine mesh of elements with which openings, if any, formed in the elevator 5 can be supplied with air. The arrangement of the openings in the elevator 5 corresponds to the arrangement of the waste part(s) 9 on the one hand, or the feed 10 on the other.For example, in the area of ​​those third openings 32 that are formed in the area of ​​the utility units, openings can be formed in the elevator 5. This proves advantageous if the breakout cylinder 4 is to be used for transporting the utility units 10.

[0149] If the use of the breakout cylinder 4 is intended for transporting waste parts 9, openings are preferably formed in the elevator 5 in the area of ​​those third openings 32 that are located in the area of ​​waste parts 9. These measures allow the components 10 or waste parts 9 to be handled differently, or fixed to the outer surface of the transport cylinder 3 or its elevator 5. The release of the components 10 or waste parts 9 can be assisted by applying compressed air to the third openings 32.

[0150] 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 insertion. Preferably, the rotary valve or the rotary insertions are formed on or associated with the end face of the transport cylinder 3. The rotary valve or the at least one rotary insertion preferably comprises a disk 18, which is associated with one of the end faces of the stripping cylinder 4. A recess X is formed in the disk 18, which preferably extends in a circular segment shape, coaxial to 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 recesses are not continuous in the circumferential direction of the disk 18 but can instead be perforated, so that several recesses are formed one behind the other on the same radius when viewed in the circumferential direction of the disk 18. Each recess corresponds, with respect to its distance (radius) to the axis of rotation of the stripping cylinder 4, to openings 58 formed in the end face of the stripping cylinder 4. Each of the openings 58 in the end face of the transport cylinder 3 communicates via further lines with either a single opening 32, a part thereof, or all of the openings 32 in the outer surface of the stripping cylinder 4. This is, of course, only valid as long as the respective opening 58 is opposite the respective recess, depending on the angular position of the stripping cylinder 4.

[0151] The disc 18 is stationary relative to the breakout cylinder 4, which rotates about its central axis during operation. The extension of the recesses in the circumferential direction of the breakout cylinder 4 defines areas of suction or blowing air, which are formed on the outer surface of the breakout cylinder 4 with respect to the angle of rotation.

[0152] In addition to these effects, the areas supplied by suction or blowing air can also be determined by the type of air supply and its activation or deactivation. For example, the area supplied by the third air supply means according to the recess can be shortened by angularly switching off the air supply. Likewise, an area supplied by the third air supply means according to the recesses can be subdivided into at least one suction area and at least one blowing area by switching the air supply between suction and blowing air. The suction area on the outer surface of the breakout cylinder 4 serves to fix the product 10 or waste parts 9, and the blowing area serves to eject them.

[0153] According to a preferred embodiment, the third air supply means are configured to switch off the suction air supply or to switch between suction air supply and blowing air supply depending on the angular position of the respective supplied third openings 32. Preferably, the third air supply means switch off the air supply to the third openings 32 or switch from suction air supply to blowing air supply when the respective third openings 32 reach a third release point through rotation of the breakout cylinder 4 about its central axis.

[0154] The disc 18 is preferably connected to a frame via a torque arm 20 and is rotatably mounted on the breakout cylinder 4. The breakout cylinder 4 is preferably rotatably mounted in the same frame to which the torque arm 20 is articulated.

[0155] To shift the areas of suction or blowing air, which are formed on the outer surface of the breakout cylinder 4 with respect to the angle of rotation, adjusting devices for rotating the disc 18 can be provided.

[0156] 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 extent larger than the diameter of a pin of the breakout cylinder 4 in the area of ​​the breakout cylinder 4 where the disc 18 is associated.

[0157] The stripping cylinder 4 and the transport cylinder 3 each carry a lift 5 for processing substrates 1, in particular for separating or stripping processed, i.e., partially cut or fully cut, web-containing or perforated substrate 1 into at least one waste part 9 and at least one blank 10. During separation or stripping, any remaining retaining webs or material connections, or intentionally incompletely cut material connections, in particular fibers or fiber bundles in the area of ​​cut lines between the waste part 9 and at least one blank 10, are torn. For this purpose, one of the lifts 5 can be designed as a die and the other as a male die. The male die has a base plane and raised areas relative to the base plane. The raised areas act on the substrate 1 and form tools.The die has a base plane and recessed areas or further cutouts opposite the base plane. The die and male die are arranged on the transport cylinder 3 and stripping cylinder 4, respectively, such that the raised areas of the male die are opposite the recessed areas or further cutouts of the die. The male die thus forms a kind of counterpart to the die. The die is arranged either on the transport cylinder 3 or the stripping cylinder 4, and the male die is arranged 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 die is arranged on the transport cylinder 3 and the male die on the stripping cylinder. The tool pair described above, male and female die, preferably differs from male and female die tool pairs used in cutting or perforating, e.g.on the processing cylinders upstream of the separating device 2. The design of the male die is determined by its function of simply pressing the elements to be separated or broken out into the recessed areas or further cutouts of the female die. Accordingly, the raised areas of the male die can have significantly smaller dimensions than the corresponding recessed areas or further cutouts of the female die. A flexographic printing plate can be used as the male die.

[0158] In an alternative embodiment, the male die has no areas raised above the base plane, but rather a base plane that is raised overall. In this case, the male die is provided with an elastic coating or made of an elastic material, at least on the side facing the female die.

[0159] During separation or stripping, waste parts 9 and usable material 10 are moved relative to each other, whereby residual webs or individual fibers or fiber bundles are torn apart in the area of ​​the cutting lines. For this purpose, either the waste parts 9 or the usable material 10 are preferably pressed by the male die into the recessed areas or the further indentations of the female die. In the case of using a male die with an elastic surface, the waste parts 9 are pressed into the recessed areas or the further indentations of the female die, whereby the surface of the male die expands at these points, while in areas of the surface outside the recesses or further indentations in the female die, the substrate is pressed against the surface of the female die.

[0160] In a further preferred embodiment, the transport cylinder 3 is not associated with a stripping cylinder 4, whereby in this embodiment as well the waste parts 9 and the usable portion 10 are moved relative to each other and residual webs or individual fibers or fiber bundles are torn apart in the area of ​​the 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 recessed areas on the surface of the transport cylinder 3. The recessed areas are further preferably associated with first openings 12, which can be in operative communication with first air supply means 14. The first air supply means 14 are preferably designed for supplying suction air.Preferably, a lift 5 is interchangeably assigned to the outer surface of the transport cylinder 3, wherein the raised areas of the surface of the transport cylinder 3 are formed by the lift 5 and the recessed areas of the surface of the transport cylinder 3 are formed by the outer surface of the transport cylinder 3 in the area of ​​openings formed in the lift 5. Second openings 13 can be formed in the raised areas and / or the recessed areas of the surface of the transport cylinder 3, which are in operative communication with second air supply means 15. Furthermore, the first and / or the second air supply means 14, 15 can be switchable between a suction air supply and a blown air supply.

[0161] To achieve the relative movement of the waste parts 9 and the usable portion 10 relative to each other, a lift 5 can be assigned to the transport cylinder 3. This lift is designed, in particular, as a die and has recessed areas or further openings. A negative pressure is applied in the area of ​​the recessed areas or further openings via the first and / or second openings 12, 13. This negative pressure moves the waste parts 9 and the usable portion 10 relative to each other, i.e., it draws the waste parts 9 into the recessed areas or the further openings, while the usable portion 10 is supported on the base plane of the die. Alternatively, it can also be provided that the usable portion 10 is drawn into the recessed areas or the further openings, 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 exerted by the negative pressure or suction air in the recessed areas or further openings on the sides of the utility 10 or waste parts 9 facing the transport cylinder 3. Openings are preferably arranged in the recessed areas. These ensure that the negative pressure applied at the first and / or second openings 12, 13 can propagate to the side of the utility 10 or waste parts 9 facing the transport cylinder 3.

[0162] When separating the substrate sheets 1 into waste parts 9 and blanks 10, problems arise, particularly in environments with low humidity, caused by unwanted 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 these electrostatic charges, the 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 force of gravity is usually insufficient 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, especially the male and female dies.

[0163] According to a further embodiment, which serves in particular to avoid problems caused by electrostatic charges, it is provided to design a separating device 2 which comprises a transport cylinder 3 and an associated breakout cylinder 4, wherein an antistatic device 95 is associated with the transport cylinder 3 and / or the breakout cylinder 4 ( Fig. 9) Preferably, the transport cylinder 3 has means for fixing an interchangeable lift 5, as well as openings 12, 13 which, when the lift 5 is fixed, are at least partially covered by openings that can be formed in the lift 5, with air supply means 14, 15 being provided for supplying the openings 12, 13 with air. The antistatic device 95 preferably comprises at least one electrode connected to at least one high-voltage source. The high-voltage source can be a positive or a negative high-voltage source. Alternatively, the high-voltage source can be switched between operating as a positive and operating as a negative high-voltage source. The high-voltage sources can be connected via a control unit to a sensor that detects the voltage applied to the surfaces of the transport cylinder 3 and / or the breakout cylinder 4 or the tools or tool parts attached to them.The control system is preferably designed to selectively activate the positive or negative high-voltage source or to switch the switchable high-voltage source depending on the sign of the applied voltage. The control system can also process the value of the applied voltage (Fig. 12) 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 a non-pulsed DC voltage.

[0164] The electrode of the antistatic device 95 preferably extends in the axial direction of the breakout cylinder 4 over its length and / or in the axial direction of the transport cylinder 3 over its length.

[0165] Furthermore or alternatively, in such further 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 breakout cylinder 4.

[0166] 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 die and male die, and / or the cylinder surfaces of transport cylinder 3 and / or a breakout cylinder 4 associated therewith, can also be designed to be antistatic, in particular with electrically conductive materials.

[0167] According to another preferred embodiment, with or without a breakout cylinder 4, a circulating conveyor belt 29 is associated with the transport cylinder 3, as shown in particular in Fig. 11 or Fig. 12. The conveyor belt 29 is preferably arranged above the transport cylinder 3. The conveyor belt 29 is preferably partially encircled by the transport cylinder 3, forming an angle of wrap. Alternatively, the conveyor belt 29 can also be encircled by the transport cylinder 3, forming a point of tangency 36.

[0168] Preferably, the tangent point 36 is located at the 12 o'clock position of the transport cylinder 3. The length of the conveyor belt 29 is determined by the arrangement of deflection rollers. Preferably, the conveyor belt 29 has a horizontally extending transport section 37. The conveyor belt 29 can, in particular, be designed as a suction belt. More preferably, suction air is present at least in the transport section 37 on the conveyor belt 29. This means that the conveyor belt 29 can be designed for the suspended transport of blanks and / or waste parts 10, 9. The conveyor belt 29 has, in particular, the function of taking processed substrate sheets 1, waste parts 9, or blanks 10 from the transport cylinder 3 at the tangent point 36 or in the area where the conveyor belt 29 wraps around it and transporting them further.

[0169] Another transport system, for example in the form of a further transport belt 30, can be connected to the conveyor belt 29. Preferably, an overlap area is formed between the conveyor belt 29 and the further conveyor belt 30, in which processed substrate sheets 1 or panels 10 and / or waste parts 9 can be transferred from the conveyor belt 29 to the further conveyor belt 30. The further conveyor belt 30 is more preferably designed for the horizontal transport of panels and / or waste parts 10, 9.

[0170] It goes without saying that instead of the further conveyor belt 30, another suitable transport system may be provided that takes over processed substrate sheets 1 or uses 10 and / or waste parts 9 from conveyor belt 29.

[0171] Instead of the additional conveyor belt 30, a container for receiving waste parts can also be arranged under the conveyor belt 30.

[0172] 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 panels 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 bridges or conveyor belt.

[0173] The operating mode of an embodiment as preferably described by the Fig. 11 or Fig. Figure 12 illustrates the device and 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. The following are further preferred: Fig. 11 or Fig. In the embodiment shown in section 12, two processing cylinders are arranged, 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, and perforating tools acting 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 hold of the processed, especially partially cut, substrate sheet 1. The substrate sheet 1 preferably comprises an edge and waste parts 9 connected to it 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 recesses at the points where it acts on blanks 10.Openings are provided in two ways: firstly, in the area of ​​the utility units 10 at the locations in the elevator 5 where first openings 12 are formed, whereby the second openings 13 in the area of ​​the utility units 10 are covered, i.e., closed, by the elevator 5; and secondly, in the area of ​​the waste items 9 at the locations in the elevator 5 where second openings 13 are formed, whereby the first openings 12 in the area of ​​the waste items 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 precisely at the tangent point A, a negative pressure is applied to the first openings 12 by the first air supply means 14, which fixes the utility units 10 to the outer surface of the transport cylinder 3 or to the elevator 5.As a result of the continued rotation of the transport cylinder 3, the blanks 10, which are held in place by the negative pressure, and the waste parts 9 reach the point of tangency B, which is formed between the transport cylinder 3 and the stripping cylinder 4. At the point of tangency B, the raised areas of the lift 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 lift 5 fixed on the transport cylinder 3. This tears away the remaining webs that connect the waste parts 9 to the frame or to good parts 10. Preferably, at the point of tangency B, a negative pressure is applied via the second air supply means 15 at 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 lift 5.Alternatively, the negative pressure can be applied via the second air supply means 15 at the second openings 13 in the area of ​​the waste parts 9 at the point of contact A or immediately thereafter. When the respective batches 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 batches 10 are no longer secured and are thus released. As a result of the negative pressure preferably applied to the conveyor belt 29, the batches 10 are lifted from the transport cylinder 3 at the transfer point or transfer area C, secured to the underside of the conveyor belt 29, and transported away suspended from it. The transfer of the batches 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 batches 10 reach the transfer point or transfer area C. The removal of the batches 10 can preferably be carried out using the further conveyor belt 30. For this purpose, the conveyor belt 29 conveys the batches 10 to the further conveyor belt 30 and transfers them to the further conveyor belt 30. For the transfer, the negative pressure applied to the conveyor belt 29 is preferably deactivated so that the batches are fixed to the further conveyor belt 30 by the effect of gravity or by additional suction and transported away from it. 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, positive pressure is applied instead of negative pressure.This results in the release or active rejection of the waste particles 9, which can then be collected by a waste container. In the area of ​​release point D, in addition to the waste particles 9, the front edge of the substrate sheet 1 is preferably also released by the gripper system 17.

[0174] Further operating mode of an embodiment as preferably described by the Fig. 11 or Fig. As illustrated in Figure 12, the process 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 hold of the processed, especially partially cut, substrate sheet 1. The substrate sheet 1 preferably comprises an edge and waste parts 9 connected to it 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 recesses at the points where it acts on blanks 10.Openings are provided in two ways: firstly, in the area of ​​the utility units 10 at the locations in the elevator 5 where first openings 12 are formed, whereby the second openings 13 in the area of ​​the utility units 10 are covered, i.e., closed, by the elevator 5; and secondly, in the area of ​​the waste items 9 at the locations in the elevator 5 where second openings 13 are formed, whereby the first openings 12 in the area of ​​the waste items 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 precisely at the tangent point A, a negative pressure is applied to the first openings 12 by the first air supply means 14, which fixes the utility units 10 to the outer surface of the transport cylinder 3 or to the elevator 5.As a result of the continued rotation of the transport cylinder 3, the blanks 10, held in place by the vacuum, and the waste parts 9 reach the point of tangency B, which is formed between the transport cylinder 3 and the stripping cylinder 4. At the point of tangency B, the raised areas of the elevator 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 elevator 5 fixed to the transport cylinder 3. This tears away the remaining webs that connect the waste parts 9 to the frame or to good parts 10. The elevator 5 fixed to 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 elevator 5 where it is not raised or where it interacts with the blanks 10 during rolling contact.When the third openings 32 of the stripping cylinder 4 reach the point of tangency B and are opposite a respective blank 10 at the point of tangency B, a vacuum is applied to them. This vacuum exerts a force that lifts the blank 10 from the surface of the transport cylinder 3. The vacuum at the third openings 32 of the stripping cylinder 4 is deactivated as soon as they leave the area of ​​the point of tangency B or a few degrees, in particular 10 degrees, thereafter. Preferably, the vacuum at the first openings 12 is deactivated when the respective first openings 12 are located in the area of ​​the point of tangency B.This ensures that the respective product 10 is briefly lifted from the surface of the transport cylinder 3 under the influence of the negative pressure at the third openings 32 of the stripping cylinder 4, i.e., for a few degrees, in particular 10 degrees, of the rotational movement of the transport cylinder 3. This measure further supports the separation of the product 10 and the waste parts 9, as they are actively moved in different directions, at least briefly. Preferably, at the point of contact B, a negative pressure is applied via the second air supply means 15 at 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 at the second openings 13 in the area of ​​the waste parts 9 at the point of contact A or immediately thereafter.When the respective modules 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 modules 10 are no longer secured and are thus released. As a result of the negative pressure preferably applied to the conveyor belt 29, the modules 10 are lifted from the transport cylinder 3 at the transfer point or transfer area C, secured to the underside of the conveyor belt 29, and transported away suspended from it. The transfer of the modules 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 to positive pressure when the first openings in the area of ​​the respective modules 10 reach the transfer point or transfer area C.The removal of the packages 10 can preferably be achieved using the additional conveyor belt 30. For this purpose, the conveyor belt 29 conveys the packages 10 to the additional conveyor belt 30 and transfers them to it. For this transfer, the negative pressure applied to the conveyor belt 29 is preferably deactivated, so that the packages are fixed to the additional conveyor belt 30 by the action of gravity or by additional suction and transported away. When the waste particles 9 reach the release point D, the negative pressure applied to the second openings 13 in the area of ​​the waste particles 9 is deactivated, or preferably, positive pressure is applied instead of negative pressure. This results in the release of the waste particles 9 or their active repulsion, which can then be collected by a waste container.In the area of ​​release point D, in addition to the waste parts 9, the front edge of the substrate arc 1 is preferably also released by the gripper system 17.

[0175] Another operating mode of an embodiment as preferably described by the Fig. 11 or Fig. Figure 12 illustrates whole-sheet processing or whole-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 hold of the processed, especially partially cut, substrate sheet 1. The substrate sheet 1 preferably comprises an edge and waste parts 9 connected to it via so-called residual webs, as well as blanks 10. The transport cylinder 3 carries a lift 5. The lift 5 has openings. The openings are located in the lift 5 at the points where first and / or second openings 12, 13 are formed.When the first and / or second openings 12, 13 have passed tangent point A as a result of the rotation of the transport cylinder 3, or are located precisely at 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. This negative pressure fixes only the utility items 10, only the waste items 9, or both the utility items 10 and the waste items 9 to the outer surface of the transport cylinder 3 or the elevator 5, respectively. As the transport cylinder 3 continues to rotate, the utility items 10 and the waste items 9 pass tangent point B. The waste items 9 and the utility items do not come into contact with any other elements at tangent point B. When the respective utility items 10 and the respective waste items 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 substrate sheets 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 transfer point or transfer area C. As a result of the negative pressure, preferably applied to the conveyor belt 29, the substrate sheets 10, the waste parts 9, and the frames of the substrate sheets 1, including the leading edges of the substrate sheets 1 still connected by the remaining webs (complete sheets), are lifted from the transport cylinder 3 at the transfer point or transfer area C, fixed to the underside of the conveyor belt 29, and transported away suspended from it.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 complete sheet, from the transport cylinder 3 to the conveyor belt 29 can be assisted by applying 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.

[0176] The removal of the complete sheets can preferably be achieved using the additional conveyor belt 30. For this purpose, the conveyor belt 29 conveys the complete sheets to the additional conveyor belt 30 and transfers them to it. For this transfer, the negative pressure applied to the conveyor belt 29 is preferably deactivated, so that the complete sheets are fixed to the additional conveyor belt 30 by the action of gravity or by additional suction and then transported away.

[0177] According to another preferred embodiment with a breakout cylinder 4, a circulating conveyor belt 29 is associated with the breakout cylinder, as shown in particular in the following. Fig. As can be seen in Figure 13. The conveyor belt 29 is preferably arranged above the transport cylinder 3. The conveyor belt 29 is preferably associated with the stripping cylinder 4 by forming a transfer point 38 or transfer area. More preferably, the conveyor belt 29 is arranged to partially encircle the stripping cylinder 4 by 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 associated with the transport cylinder 3 in the 12 o'clock position of the transport cylinder 3. The extent of the conveyor belt 29 is determined by the arrangement of deflection rollers. Preferably, the conveyor belt 29 has a first transport area 39 that 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 section 40, which runs at least approximately horizontally, and in particular exactly horizontally. Specifically, the conveyor belt 29 is a suction belt, and the first transport section 39 is a section in which suction air is applied to the conveyor belt 29. The conveyor belt 29 has the function, in particular, of receiving processed substrate sheets 1, waste parts 9, or blanks 10 from the stripping cylinder 4 at the transfer point 38 or transfer section 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. Preferably, an overlap section 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.It is understood that instead of the additional conveyor belt 30, another suitable transport system can also be provided that takes processed substrate sheets 1 or panels 10 and / or waste parts 9 from the conveyor belt 29. In addition to the conveyor belt 29, the transport cylinder 3 can also be directly connected to another transport system 76, i.e., forming a transfer area or transfer point between the transport cylinder 3 and the additional transport system 76 for processed substrate sheets 1 or panels 10 and / or waste parts 9. This additional transport system 76 is preferably designed as a sheet guide cylinder or sheet guide 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 configured to switch between suction air supply and blown air supply depending on the angular position of the respective third openings 32 being supplied. More preferably, the third air supply means are configured 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, through rotation of the stripping cylinder 4 about its axis of rotation. The third openings 32 can be groove-shaped or perforated.The third air supply means preferably comprise a rotary valve or a rotary insertion, wherein the at least one rotary valve or the at least one rotary insertion can be formed on the end face of the breakout cylinder 4. Like the transport cylinder 3, the breakout cylinder 4 preferably has means for fixing an interchangeable lift 5. The fixing means are preferably designed as clamping grippers. With them, each lift 5 can be fixed at its trailing edge and its leading edge. The means for fixing the leading edge of the lift 5 are preferably formed by the leading edge clamping element 22 and the further clamping element 24, which interacts correlatively with it to form a clamping gap. The leading edge clamping element 22 is mounted on the base body of the breakout cylinder 4. The further clamping element 24 can, in particular, be designed 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. The trailing edge of the elevator 5 can be fixed between a trailing edge clamping element 47 and a further trailing edge clamping element 48, which together form a further clamping gap. The force required to close the trailing edge clamping element is applied by a rotatable clamping shaft 50, which acts on the trailing edge clamping element 47 via a toggle lever 51.

[0178] Further preferred details of the breakout cylinder 4 are in Fig. Figure 10 and the accompanying description, to which reference is made in connection with the described embodiment. A lift 5 with openings is preferably fixed to the breakout cylinder 4. The openings in the lift 5 of the breakout cylinder 4 correspond to the third openings 32 of the breakout cylinder 4. The openings are preferably formed in the area of ​​the lift 5 where it is not raised and interacts with the blanks 10 during rolling contact. When the third openings 32 of the breakout cylinder 4 reach the tangent point B and are opposite a respective blank 10 at tangent point B, a vacuum is applied to them. As a result of this vacuum, a force is exerted that lifts the blanks 10 from the surface of the transport cylinder 3.

[0179] A preferred operating mode of an embodiment as preferably described by the Fig. As illustrated in Figure 13, the process 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 hold of the processed, especially partially cut, substrate sheet 1. The substrate sheet 1 preferably comprises an edge and waste parts 9 connected to it 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 recesses at the points where it acts on blanks 10.Openings are preferably provided, firstly, in the area of ​​the utility units 10 at the locations in the elevator 5 where first openings 12 are formed, wherein the second openings 13 in the area of ​​the utility units 10 are covered, i.e., closed, by the elevator 5. Secondly, openings are preferably also provided in the area of ​​the waste parts 9 at the locations 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 precisely at the tangent point A, a negative pressure is applied to the first openings 12 by the first air supply means 14, which fixes the utility units 10 to the outer surface of the transport cylinder 3 or to the elevator 5.As a result of the continued rotation of the transport cylinder 3, the blanks 10, held in place by the vacuum, and the waste parts 9 reach the point of tangency B, which is formed between the transport cylinder 3 and the stripping cylinder 4. At the point of tangency B, the raised areas of the lift 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 lift 5 fixed to the transport cylinder 3. This tears away the remaining webs that connect the waste parts 9 to the frame or to good parts 10. The lift 5 fixed to 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 lift 5 where it is not raised or where it interacts with the blanks 10 during rolling contact.When the third openings 32 of the stripping cylinder 4 reach the tangent point B and are opposite or immediately in front of a respective blank 10 at tangent point B, a vacuum is applied to them. This vacuum exerts a force that lifts the blank 10 from the surface of the transport cylinder 3. Preferably, the vacuum 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 tangent point B. This ensures that the respective blank 10 is lifted from the surface of the transport cylinder 3 under the influence of the vacuum at the third openings 32 of the stripping cylinder. The vacuum applied to the second openings 13 is preferably maintained when the respective second openings 13 pass tangent point B.This holds the waste pieces 9 on the surface of the transport cylinder 4 and transports them 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. The stripping cylinder 4, due to its rotation, transports the blanks 10, which are held in place by negative pressure, further towards the conveyor belt 29 until they reach the transfer point or transfer area E between the stripping cylinder 4 and the conveyor belt 29. At the transfer point or transfer area E between the stripping cylinder 4 and the 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, an overpressure can be built up at the third openings 32 following the deactivation of the negative pressure. The described forces transfer the respective blanks 10 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 or storage 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 again enter the tangent point B.Preferably at the point of contact B, a negative pressure is applied via the second air supply means 15 at the second openings 13 in the area of ​​the waste particles 9, which fixes the waste particles 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 at the second openings 13 in the area of ​​the waste particles 9 at the point of contact A or immediately thereafter. When the waste particles 9 reach the release point D, the negative pressure applied at the second openings 13 in the area of ​​the waste particles 9 is deactivated, or preferably, a positive pressure is applied instead of the negative pressure. This results in the release of the waste particles 9 or their active repulsion, which can then be picked up by a waste container. In the area of ​​release point D, in addition to the waste particles 9, the front edge of the substrate sheet 1 is preferably also released by the gripper system 17.

[0180] Another operating mode of an embodiment as preferably described by the Fig. Figure 13 illustrates whole-sheet processing or whole-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 hold of the processed, especially partially cut, substrate sheet 1. The substrate sheet 1 preferably comprises an edge and waste parts 9 connected to it via so-called residual webs, as well as blanks 10. The transport cylinder 3 carries a lift 5. The lift 5 has openings. The openings are located in the lift 5 at the points where first and / or second openings 12, 13 are formed.When the first and / or second openings 12, 13 have passed tangent point A as a result of the rotation of the transport cylinder 3, or are located precisely at 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. This negative pressure secures only the utility items 10, only the waste items 9, or both the utility items 10 and the waste items 9 to the outer surface of the transport cylinder 3 or the elevator 5, respectively. When the respective utility items 10 and waste items 9 reach 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 area of ​​the first and / or openings 12, 13 is no longer present, and the utility items 10 and waste items 9 are no longer secured and are thus released.The fixation of the leading edges of the substrate sheets 1 by the gripper system 17 is also released at tangent point B. When the third openings 32 of the stripping cylinder 4 reach tangent point B and are opposite or immediately in front of a respective blank 10 at tangent point B, a vacuum is applied to them. As a result of this vacuum, a force is exerted that lifts the blank 10 from the surface of the transport cylinder 3. Preferably, the vacuum 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 tangent point B.As a result of the negative pressure preferably applied at the third openings 32, the blanks 10, the waste parts 9, and the frames of the substrate sheets 1, including the leading edges of the substrate sheets 1 still connected by the remaining webs (complete sheets), are lifted from the transport cylinder 3 at the tangent point B and transferred to the stripping cylinder 4. The transfer of the blanks 10, the waste parts 9, and the frames of the substrate sheets 1, including the leading edges of the substrate sheets 1, as a complete 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 sheet blanks, held in place by negative pressure, further towards the conveyor belt 29 as a result of its rotation, until they reach the transfer point or transfer area E between the stripping cylinder 4 and the conveyor belt 29. At the transfer point or transfer area E between the stripping cylinder 4 and the conveyor belt 29, a suction effect is preferably exerted on the side of the sheet blank 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, positive pressure can be built up at the third openings 32 after the negative pressure has been deactivated. Due to the forces described, the sheet blanks 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 complete sheets preferably to a stacking 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 again reach the tangent point B.

[0181] According to another preferred embodiment, with or without a breakout cylinder 4, a peeling device 31 (also called a peeling assembly) is associated with the transport cylinder 3, as shown in particular in Fig. As can be seen in Figure 14. The peeling device 31 preferably has a support surface that extends in the direction of a virtual tangent to the transport cylinder 3. The support surface can be horizontally oriented. The peeling device 31 is further preferably associated with a circulating conveyor belt 29, which can be designed as a suction belt circulating over deflection rollers. The peeling device 31 is preferably associated with 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 12 o'clock position. The conveyor belt 29 preferably has a transport area 37 that 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 area 37 lie in one and the same virtual plane.Furthermore, the support surface and the transport area 37 preferably extend in the direction of a virtual tangent applied to the transport cylinder 3.

[0182] The transport cylinder 3 and the optional breakout cylinder 4 can be designed according to those embodiments of transport cylinder 3 and breakout cylinder 4 as they are described in particular in connection with the items according to the Fig. 9, Fig. 10, Fig. 11, Fig. 12 to Fig. 13 have already been described.

[0183] The peeling device 31 has, in particular, the 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 associated elevator 5 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 area 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.

[0184] It goes without saying that instead of the further conveyor belt 30, another suitable transport system may be provided which takes over processed substrate sheets 1 or uses 10 and / or waste parts 9 from conveyor belt 29.

[0185] Instead of the additional conveyor belt 30, a container for receiving waste parts 9 can also be arranged under the conveyor belt 29.

[0186] 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 76 for processed substrate sheets 1 or panels 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 bridges or conveyor belt.

[0187] The operating mode of an embodiment as preferably described by the Fig. The embodiment of the device for treating substrates 1, as illustrated in Figure 14, can be described as follows. The illustrated embodiment of the device is preferably a component of a sheet-fed printing press. The sheet-fed printing press can comprise one or more printing units 6. The embodiment shown in Figure 14 is preferably a component of a sheet-fed printing press. ... Fig. In the embodiment shown in Figure 14, two processing cylinders are arranged in front of the substrate 1, between which the substrate 1 can be inserted. The substrate 1 undergoes processing as it passes through tool components acting in the cylinder gap, from the group consisting of cutting tools, punching tools, creasing tools, and perforating tools. 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 hold of the processed, in particular partially cut, substrate sheet 1. The substrate sheet 1 preferably comprises an edge and waste parts 9 connected to it 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 recesses at the points where it acts on blanks 10.Openings are provided in two ways: firstly, in the area of ​​the utility units 10 at the locations in the elevator 5 where first openings 12 are formed, whereby the second openings 13 in the area of ​​the utility units 10 are covered, i.e., closed, by the elevator 5; and secondly, in the area of ​​the waste items 9 at the locations in the elevator 5 where second openings 13 are formed, whereby the first openings 12 in the area of ​​the waste items 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 precisely at the tangent point A, a negative pressure is applied to the first openings 12 by the first air supply means 14, which fixes the utility units 10 to the outer surface of the transport cylinder 3 or to the elevator 5.As a result of the continued rotation of the transport cylinder 3, the blanks 10, fixed by the negative pressure, and the waste parts 9 reach the point of tangency B, which is formed between the transport cylinder 3 and the stripping cylinder 4. At the point of tangency B, the raised areas of the lift 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 lift 5 fixed on the transport cylinder 3. This tears apart the remaining webs that connect the waste parts 9 to the frame or to good parts (blanks) 10. Preferably, at the point of tangency B, a negative pressure is applied via the second air supply means 15 at 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 lift 5.Alternatively, the negative pressure can be applied via the second air supply means 15 at the second openings 13 in the area of ​​the waste particles 9 either at the point of contact A or immediately thereafter. As a result of the rotation of the transport cylinder 3, the packages 10 and the waste particles 9 are transported past the point of contact B until they finally reach the transfer point F between the transport cylinder 3 and the peeling device 31. Before the respective packages 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 packages 10 are no longer fixed and are repelled from the surface of the transport cylinder 3 or from its elevator 5 to the extent that the positive pressure builds up at the first openings 12.This means that at least the leading edges of the blanks 10, viewed in the direction of rotation of the transport cylinder 3, project radially beyond the peeling device 31. The peeling device 31 is directed into the gap formed between the leading 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 enter the detection range of the conveyor belt 29, which transports the blanks 10 away. Unlike the first openings 12, the negative pressure at the second openings 13 is maintained by the second air supply 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 at 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 enter the area of ​​the release point D. With the aforementioned process steps, not only is the fixation of the waste particles 9 terminated upon reaching the release point D, but preferably the lifting of the waste particles 9 is also pneumatically assisted in addition to the force of gravity. In the area of ​​the release point D, in addition to the waste particles 9, the leading edge of the substrate sheet 1 is preferably also released by the gripper system 17.

[0188] Another operating mode of an embodiment as preferably described by the Fig. Figure 14 illustrates whole-sheet processing or whole-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 hold of the processed, especially partially cut, substrate sheet 1. The substrate sheet 1 preferably comprises an edge and waste parts 9 connected to it via so-called residual webs, as well as blanks 10. The transport cylinder 3 carries a lift 5. The lift 5 has openings. The openings are located in the lift 5 at the points where first and / or second openings 12, 13 are formed.When the first and / or second openings 12, 13 have passed tangent point A as a result of the rotation of the transport cylinder 3, or are located exactly at 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. This negative pressure fixes only the blanks 10, or only the waste parts 9, or both the blanks 10 and the waste parts 9 to the outer surface of the transport cylinder 3 or the elevator 5, respectively. As a result of the further rotation of the transport cylinder 3, the blanks 10 and the waste parts 9 pass tangent point B. The waste parts 9 or the blanks 10 do not come into contact with any other elements at tangent point B. The stripping cylinder 4 is disconnected from the transport cylinder 3.When the respective utility units 10 and 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 compressed air supply. The negative pressure in the area of ​​the first and / or second openings 12, 13 is no longer present, and the utility units 10, 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 each other by the residual webs (complete sheets), are no longer fixed and are thus released at the transfer point F and preferably selectively lifted from the surface of the transport cylinder 3 or from the lift 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 complete sheets are then pushed over the support surface of the peeling device 31 until they enter the working area of ​​the conveyor belt 29, from which they are transported away.

[0189] The operating mode of an embodiment as preferably described by the Fig. As illustrated in Figure 15, the process 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 hold of the processed, especially partially cut, substrate sheet 1. The substrate sheet 1 preferably comprises an edge and waste parts 9 connected to it 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 recesses at the points where it acts on blanks 10.Openings are provided in two ways: firstly, in the area of ​​the utility units 10 at the locations in the elevator 5 where first openings 12 are formed, with the second openings 13 in the area of ​​the utility units 10 being covered, i.e., closed, by the elevator 5; and secondly, in the area of ​​the waste items 9 at the locations in the elevator 5 where second openings 13 are formed, with the first openings 12 in the area of ​​the waste items 9 being 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, a negative pressure is applied to the first openings 12 by the first air supply means 14, which fixes the utility units 10 to the outer surface of the transport cylinder 3 or to the elevator 5.As a result of the continued rotation of the transport cylinder 3, the blanks 10, held in place by the vacuum, and the waste parts 9 reach the point of tangency B, which is formed between the transport cylinder 3 and the stripping cylinder 4. At the point of tangency B, the raised areas of the elevator 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 elevator 5 fixed to the transport cylinder 3. This tears away the remaining webs that connect the waste parts 9 to the frame or to good parts 10. The elevator 5 fixed to 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 elevator 5 where it is not raised or where it interacts with the blanks 10 during rolling contact.When the third openings 32 of the stripping cylinder 4 reach the point of tangency B and are opposite a respective blank 10 at the point of tangency B, a vacuum is applied to them. This vacuum exerts a force that lifts the blank 10 from the surface of the transport cylinder 3. The vacuum at the third openings 32 of the stripping cylinder 4 is deactivated as soon as they leave the area of ​​the point of tangency B or a few degrees, in particular 10 degrees, thereafter. Preferably, the vacuum at the first openings 12 is deactivated when the respective first openings 12 are located in the area of ​​the point of tangency B.This ensures that the respective product 10 is briefly lifted from the surface of the transport cylinder 3 under the influence of the negative pressure at the third openings 32 of the stripping cylinder 4, i.e., for a few degrees, in particular 10 degrees, of the rotational movement of the transport cylinder 3. This measure further supports the separation of the product 10 and the waste parts 9, as they are actively moved in different directions, at least briefly. Preferably, at the point of contact B, a negative pressure is applied via the second air supply means 15 at 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 at the second openings 13 in the area of ​​the waste parts 9 at the point of contact A or immediately thereafter.As a result of the rotation of the transport cylinder 3, the blanks 10 and the waste pieces 9 are transported past the contact 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 are repelled from the surface of the transport cylinder 3 or from its elevator 5 to the extent that the positive pressure builds up at the first openings 12. Thus, at least the leading edges of the blanks 10, viewed in the direction of rotation of the transport cylinder 3, protrude radially beyond the peeling device 31.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 enter the detection range of the conveyor belt 29, which transports the blanks 10 away. Unlike the first openings 12, the negative pressure at the second openings 13 is maintained by the second air supply 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 at the second openings 13 is deactivated. In a preferred embodiment, positive pressure can also be applied to the second openings 13 when they enter the area of ​​the release point D.The aforementioned process steps not only terminate the fixation of the waste particles 9 upon reaching the release point D, but preferably also assist the lifting of the waste particles 9 with pneumatic means in addition to the force of gravity. In the area of ​​the release point D, in addition to the waste particles 9, the front edge of the substrate sheet 1 is preferably also released by the gripper system 17.

[0190] Instead of the conveyor belt 29, the transport cylinder 3 can also be directly assigned to another transport system 76, i.e., forming a transfer area or transfer point between the transport cylinder 3 and the other transport system 76 for processed substrate sheets 1 or panels 10 and / or waste parts 9. This other transport system 76 is preferably designed as a sheet guide cylinder or sheet guide drum or sheet guide system, in particular a chain conveyor system with gripper bridges, or a conveyor belt. An embodiment with a chain conveyor system with gripper bridges as part of the delivery 99 of a sheet-fed printing press is described in Fig. 17 shown.

[0191] The chain conveyor system includes traction elements moved by drive and deflection devices, which power gripping devices, in particular gripper bridges, for substrate conveying. The gripping devices have fixing elements for taking hold and securing the arc-shaped substrates 1. Clamping and / or suction grippers can be used as fixing elements for gripping the substrate edges. In further developments not shown, additional gripping devices are provided for the trailing edges of the substrates. The arc conveyor system, designed here as a chain conveyor system, includes 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. From the gripper bridges, the substrates 1 are conveyed in the transport direction to the delivery stack, which is stored, for example, on a pallet or another type of transport surface.The gripper bridges preferably contain front edge clamping grippers which have gripper fingers that interact with the gripper bridges, which are spaced apart from each other on a gripper shaft and can be controlled by it.

[0192] For the safe transport of the substrates 1 held by the gripper bridges, a substrate guiding device and, for example, a dryer are provided in the delivery unit 99. The substrate guiding device has substrate guide plates facing the gripper bridges, which are equipped with air nozzles and extend across the width of the machine. Air chambers are arranged under the substrate guide plate, through which the air nozzles are supplied with compressed air, so that a cushion of air is formed between the substrate guide plate and the substrates 1 transported by the gripper bridges. A coolant circuit can be integrated to regulate heating of the substrate guide plate in the area of ​​the dryer.To prevent the substrates 1 from sticking together on the delivery stack, a release agent application device, in particular a powder device, preferably combined with a device for extracting the powder, is preferably provided in the area of ​​the delivery 99.

[0193] In front of the delivery stack, an unspecified braking device is arranged to decelerate the substrates 1 released by the gripper bridges. The braking device may include rotating suction rings and / or circulating suction belts or be designed as a secondary gripper system. The substrates 1, decelerated by the braking device, rest against front stops and are thus aligned and placed on the delivery stack. The delivery stack is preferably lowered by a stack lift drive by the thickness of each substrate placed, so that the stack surface maintains a nearly constant level.

[0194] Another operating mode of an embodiment, as preferably described by the Fig. The process illustrated in Figure 17 is described below. The substrates 1 to be processed are stored as stacks of substrate sheets in the feeder 7. From this stack, they are separated and successively fed either to one or more printing units 6 for printing, or, if no printing units 6 are used, 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 successively inserted into a cylinder gap formed between two processing cylinders and die-cut in such a way that each substrate sheet 1 becomes a die-cut sheet (processed substrate sheet 1), which consists of at least one blank 10, at least one waste portion 9, and a surrounding frame. The blank 10, waste portion 9, and frame are held together by incomplete material connections.The processing cylinders can be designed as tool-carrying die-cutting 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 partially cut, substrate sheet 1. The transport cylinder 3 preferably carries a lift 5. The lift 5 has openings. The openings are provided at the locations in the lift 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 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 openings 12, 13 by the first and / or second air supply means 14, 15. This negative pressure fixes the blanks 10, or only the waste parts 9, or both the blanks 10 and the waste parts 9 to the outer surface of the transport cylinder 3 or to the lift 5, respectively. 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, which is formed between the transport cylinder 3 and the stripping cylinder 4. At the tangent point B, the raised areas of the lift 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 lift 5 fixed to the transport cylinder 3.In this process, the incompletely severed material connections that link the waste parts 9 to the frame or to the panel 10 are separated, i.e., torn apart. 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 breakout cylinder 4 are preferably raised. The crucial point is that the raised or recessed areas on the transport cylinder 3 and an associated breakout cylinder 4 are designed in such a way that the incompletely severed material connections are separated, i.e., torn apart.

[0195] As a result of the rotation of the transport cylinder 3, the usable items 10 and the waste items 9 are transported past the destination point B until they finally reach the transfer point F between the transport cylinder 3 and the further transport system 76.

[0196] At transfer point F, the frames with the utility units 10 adhering to them exclusively via incompletely severed material connections are transferred to a stacking device, in particular a delivery unit 99, and more preferably to a respective gripper bridge of the delivery unit 99, from which they are preferably transported to a stacking carrier and stacked.

[0197] When the waste particles 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 particles 9 reach the release point D is the suction air supply to the first and / or second openings 12, 13 discontinued or preferably switched to a blown air supply, so that the waste particles 9 are released or preferably actively ejected.

[0198] In connection with the separation processes between transport cylinder 3 and breakout cylinder 4, it proves advantageous in preferred embodiments to only remove selected, incompletely severed material connections and to selectively maintain others in order to maintain the stability required for the further transport of the frame and the associated panels 10. Accordingly, it is preferably provided that, between transport cylinder 3 and breakout cylinder 4, the incompletely severed material connections between the rear frame section (in the transport direction) and the panels 10 are removed, and the incompletely severed material connections between the front frame section (in the transport direction) and the panels 10 are maintained. Furthermore, the incompletely severed material connections between the side frame sections (in the transport direction) and the panels 10 can also be removed.

[0199] Furthermore, the incompletely severed material connections between several utility units 10 are preferably maintained between transport cylinder 3 and breakout cylinder 4.

[0200] The method described above can be used in particular by employing one of the described embodiments of the device for treating substrates 1, especially by employing the one described in Fig. 17 depicted and in relation to Fig. The device described in section 17 will be used.

[0201] Another preferred embodiment is particularly in Fig. Figure 16 is shown and will be described in more detail below. The embodiment comprises a transport cylinder 3, which in its basic structure is similar to that shown in the Fig. 2 can correspond to the transport cylinder 3 shown, so that this refers in particular to the Fig. 2 and the associated descriptive sections, as well as additionally the Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 to Fig. Reference is made to section 8, including related descriptive sections. A breakout cylinder 4 can be assigned to the transport cylinder 3, the basic structure of which is similar to that described in the Fig. 10 can correspond to the breakout cylinder 4 shown, so that this refers to the Fig. Reference is made to section 10 and the associated description sections.

[0202] The transport cylinder 3 and / or the breakout cylinder 4 preferably have means for fixing an interchangeable lift 5.

[0203] In a preferred embodiment with a transport cylinder 3 without an associated breakout cylinder 4, the means for feeding the interchangeable lift 5 are associated with the transport cylinder 3. In a further preferred embodiment with a transport cylinder 3 with an associated breakout cylinder 4, the means for feeding the interchangeable lift 5 are associated with the transport cylinder 3 or the breakout cylinder 4, or with both the transport cylinder 3 and the breakout cylinder 4.

[0204] The means for feeding the interchangeable lift 5 comprise, if associated with the transport cylinder 3, a pressure means 60 that can be selectively attached to and detached from the transport cylinder 3, in particular pivotable, and if associated with the breakout cylinder 4, a pressure means 61 that can be selectively attached to and detached from the breakout cylinder 4, in particular pivotable. The pressure 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 over the entire width of the respective cylinder (transport cylinder 3 or breakout cylinder 4) or only over a portion of its width. Likewise, the cylinder can be formed by several rollers aligned with respect to their axis of rotation. The roller or cylinder is freely movable or, in a preferred embodiment, driven by a motor.Preferably, the roller or cylinder can also be equipped with a motor that drives and / or brakes it. The roller or cylinder can also be equipped with a suitable braking device, for example, in the form of a friction brake.

[0205] 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.

[0206] The means for feeding the interchangeable lift 5 preferably comprise a guide roller 66, 67 and / or a guide rail 68, 69. More preferably, the at least one guide roller 66, 67 is associated with a movably mounted guard 70, 71. A sensor for detecting the position of the guard 70, 71 may be associated with it.

[0207] The means for supplying the interchangeable elevator 5 can further comprise a storage unit 72, 73 capable of accommodating several elevators 5. The storage unit 72, 73 is designed to hold at least one elevator 5, while at least one further elevator 5 is arranged on the transport cylinder 3 or the breakout cylinder 4, against which the stored elevator 5 can be alternately exchanged. The storage unit 72, 73 preferably accommodates not only an elevator 5 being supplied but also an elevator 5 being discharged or to be discharged. The storage unit 72, 73 preferably has separate storage locations for an elevator 5 being supplied and an elevator 5 being discharged.

[0208] The means for supplying the interchangeable elevator 5 may further comprise a pre-positioning device, in particular positioning pins. The pre-positioning device is preferably associated with the storage unit 72, 73.

[0209] To position an elevator 5 on the transport cylinder 3, the transport cylinder 3 is first rotated into a receiving position designed to accommodate the elevator 5. The rotation of the transport cylinder 3 can be accomplished using an individual drive associated with it or via a gear train that connects the transport cylinder 3 to other cylinders and into which a main drive engages. In the receiving position, the means for fixing the front edge of the interchangeable elevator 5 are at least approximately opposite the storage unit 72. The elevator 5 to be fed rests with its lower edge (which corresponds to the front edge when fixed on the transport cylinder 3) on a storage unit 72 designed as a rail 72, preferably an angle rail. According to a preferred embodiment, positioning means, for example in the form of positioning pins, are associated with the storage unit 72, which correspond to positioning recesses in the elevator 5.In the case of positioning pins, the positioning recesses in the elevator 5 are opposite the positioning pins, and the elevator 5 is pre-aligned by the assignment of the positioning recesses to the positioning pins. To feed the elevator 5, the lower edge of the elevator 5 is released from the rail 72 by pivoting or rotating the rail 72 by motor, or by manually lifting the front edge of the elevator 5 from the rail 72. The guard 70, which is pivotably mounted and preferably has a guide roller 66 at its end, is pivoted manually or by motor to create an access opening through which the elevator 5 can be fed to the means for fixing the elevator 5.Once the leading edge of the lift 5 has passed through the access opening opened by guard 70 and guide roller 66, guard 70 is pivoted back to its initial position, either manually or by a motor. This allows the guide roller 66 to contact the lift 5, guiding it towards the clamping gap formed between clamping jaw 22 and the stop 24. The lift 5 is preferably fed by gravity, or alternatively by a motor or manually. When the leading edge of the lift 5 reaches the clamping gap, lever 21 is pivoted, thus fixing the leading edge of the lift 5 between clamping jaw 22 and the stop 24. The transport cylinder 3 is then rotated counterclockwise by a motor. Once the leading edge of the lift 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 engages the lift 5 and presses it against the outer surface of the transport cylinder 3. The transport cylinder 3 is then rotated counterclockwise by the motor, and within the area of ​​influence of the pressure roller 60, the lift 5 is pressed against the outer surface of the transport cylinder 3 until the trailing edge of the lift 5 reaches the clamping gap formed between the clamping jaw 47 and the stop 48. Once the trailing edge of the lift 5 is inserted into the clamping gap, the clamping shaft 50 is rotated, thus closing the clamping gap. The pressure roller 60 then pivots away. To remove the lift 5 from the transport cylinder 3, the pressure roller 60 remains pivoted away from the transport cylinder 3.Either the front edge or the rear edge of the elevator 5 is released by the transport cylinder 3, and the transport cylinder 3 is then rotated so that the elevator 5 is conveyed again towards the storage unit 72. Finally, the previously fixed edge of the elevator 5 is released.

[0210] The arrangement of a lift 5 on the breakout cylinder 4 is comparable to the arrangement of a lift 5 on the transport cylinder 3, so that reference is preferably made to the latter unless differences are expressly described.

[0211] To mount a lift 5 on the breakout cylinder 4, the breakout cylinder 4 is first rotated into a receiving position designed to accommodate the lift 5. The rotation of the breakout cylinder 4 can be accomplished by means of an individual drive associated with it or via a gear train that connects the breakout cylinder 4 to other cylinders and into which a main drive engages. Preferably, the breakout cylinder 4 is driven by an individual drive, whereas the drive of the transport cylinder 3 is effected via a gear train that connects the transport cylinder 3 to other cylinders and into which a main drive engages.

[0212] In the receiving position, the means for fixing the trailing edge of the replaceable lift 5 are at least approximately opposite the storage area 73. The lift 5 to be fed rests with its lower edge (which corresponds to the trailing edge in the state fixed on the breakout cylinder 4) on a storage area 73 encompassed by retaining pins. In a preferred embodiment, the retaining pins are designed as positioning means in the form of positioning pins that correspond to positioning recesses in the lift 5. In the case of positioning pins, the positioning recesses in the lift 5 are opposite the positioning pins, and the lift 5 is pre-aligned by the assignment of the positioning recesses to the positioning pins. To feed the lift 5, the lower edge of the lift 5 is released from the retaining pins by retracting the retaining pins or by manually lifting the trailing edge from the retaining pins.The pivotably mounted guard 71, which preferably carries a guide roller 67 at its end, is pivoted manually or by motor, so that an access opening is created through which the elevator 5 can be supplied to the means for fixing the elevator 5.

[0213] As soon as the trailing edge of the lift 5 has passed through the access opening released by guard 71 and guide roller 67, guard 71 is pivoted back to its initial position, either manually or by a motor. This allows the guide roller 67 to contact the lift 5, guiding it towards the clamping gap formed between the clamping jaw 22 and the stop 24. The lift 5 is preferably fed by gravity, or alternatively by a motor or manually. When the trailing edge of the lift 5 reaches the clamping gap, the pneumatic muscle 25 is released, thus fixing the trailing edge of the lift 5 between the clamping jaw 22 and the stop 24. The breakout cylinder 4 is then rotated clockwise by a motor. Once the trailing edge of the lift 5 has moved under the pressure roller 61 due to the rotation of the breakout cylinder 4, the linear drive 65 is activated.The linear drive 65 pivots the pressure lever 63 until the pressure roller 61 engages the lift 5 and presses it against the outer surface of the breakout cylinder 4. The breakout cylinder 4 is then rotated further clockwise by the motor, and within the influence area of ​​the pressure roller 61, the lift 5 is pressed against the outer surface of the breakout cylinder 4 until the leading edge of the lift 5 reaches the clamping gap formed between the clamping jaw 47 and the strike plate 48. Once the leading edge of the lift 5 is inserted into the clamping gap, the clamping shaft 50 is rotated, thus closing the clamping gap. The pressure roller 61 then pivots away. To remove the lift 5 from the breakout cylinder 4, the pressure roller 61 remains pivoted away from the breakout cylinder 4.Either the front edge or the rear edge of the elevator 5 is released by the breakout cylinder 4, and the breakout cylinder 4 is then rotated so that the elevator 5 is conveyed again towards the storage unit 73. Finally, the previously fixed edge of the elevator 5 is released.
