Description

[0001] The invention relates to a processing machine according to the preamble of claim 1 and a method for adjusting a tension of at least one rotating means of motion according to the preamble of claim 19.

[0002] In the production of packaging, web- or sheet-shaped materials are used. In several processing steps, the substrates are, for example, printed, embossed, scored, perforated, die-cut, cut, stapled, glued, and folded into packaging. To optimally utilize the surface area of ​​a sheet-shaped substrate, also called a sheet, several identical or different copies, such as a poster, a folding box, or a package, are usually printed on a single sheet and then die-cut. These copies are referred to as a unit.

[0003] A processing machine can include various processing steps such as printing, cutting, embossing, creasing, die-cutting, perforating, gluing, and / or stapling. Such processing machines often also feature inspection devices. Sheets are typically processed and trimmed in processing machines with form-based die-cutting and cutting units. Such a processing machine is, for example, a die-cutting, cutting, perforating, embossing, and / or creasing machine. When such a processing machine is referred to as a die-cutting machine below, this specifically includes a cutting, perforating, embossing, and / or creasing machine. In form-based systems, in addition to rotary die-cutting, there are also flatbed die-cutting machines.

[0004] In flatbed die-cutting machines, several individual sheets are processed sequentially by a cyclically repeating movement. The sheets are moved largely horizontally through the sheet-processing units of the machine, particularly a die-cutting unit and / or a stripping unit, by a transport system, preferably a chain gripper system. In addition to the die-cutting unit, such a machine also includes other units, such as a sheet feeder unit, a sheet delivery unit, and / or a stripping unit. For example, a sheet inserter unit, a blank separator unit, and / or a remnant delivery unit may also be provided. The processed, preferably sheet-shaped, substrates are collected in the delivery unit into delivery stacks and then transported away.

[0005] The chain gripper system guides gripper beams, designed to hold the substrate at its leading edge, along at least one chain through the processing unit. The chain forms a loop, with the gripper beams being transported from outside the substrate transport path back to a receiving position to pick up a new substrate. Due to their movement patterns, wear, and / or other external influences such as temperature variations, the length of the chain changes during the course of a processing operation.

[0006] US Patent 10,753,434 B2 discloses a sheet metal processing machine with a chain gripper system comprising a chain tensioning device. This chain tensioner has a transmission element supported by a movable bracket. A rotatable element is designed to be rotated by an actuator controlled synchronously with the machine angle and to interact with the transmission element to exert a thrust force on the movable bracket. The chain tension differs for a minimum and a maximum end angular position of the rotatable element.

[0007] The invention is based on the objective of creating a processing machine and a method for adjusting the tension of at least one rotating moving means.

[0014] In a method for setting a tension of at least one rotating means of motion of at least one transport system of a machine tool, the at least one rotating means of motion is tensioned by the at least one clamping device with the at least one clamping means.

[0015] In a preferred embodiment of the method, at least one moving element makes first contact with the at least one clamping element at the first contact point with respect to the chain transport direction.

[0017] Preferably, additionally or alternatively, the at least one positioning system causes an adjustment of the at least one clamping device depending on the existing tension of the at least one rotating motion element.

[0018] In a preferred additional or alternative embodiment of the method, an adjustment of the at least one clamping device is controlled based on a force and / or on a quantity proportional to the force and / or on a position-based basis, depending on a given tension of the at least one rotating means of motion.

[0019] The advantages of the invention consist in particular of an improvement to the at least one clamping device. The design of the transport system, especially the clamping device, is advantageously simplified.

The mounting of the at least one clamping device is advantageously simplified. Advantageously, the position of guide elements of at least one guide device does not need to be changed when adjusting the tension of the at least one motion element.

[0021] Advantageously, the at least one adjustment system for the at least one clamping device is simplified. Vibrations of the moving element are preferably reduced. The force application for adjusting the at least one clamping device is advantageously optimized. Advantageously, applied forces are absorbed by the axis of the at least one clamping device, for example, its bearing.

[0022] Advantageously, the tension adjustment options are increased. Advantageously, the at least one clamping device is adjusted by a common adjustment system in response to tension changes caused by various factors. Advantageously, a change in the tension of the at least one moving element within a machine cycle due to the substrate processing operations is compensated. A tension change of the at least one moving element, in particular an elongation of the at least one moving element due to wear and tear, for example, is compensated in a particularly advantageous manner. The at least one adjustment system advantageously combines a clocked adjustment with a tension-dependent adjustment, especially without these offsetting each other through the generation of a counteracting effect.

For example, the stripping tools are spaced apart from each other only by the at least one substrate 02, or, if no substrate 02 is present in the stripping unit 400, they are preferably in direct contact with each other. Preferably, the at least one upper stripping tool is spaced further apart from the at least one lower stripping tool in an open position of the stripping unit 401 at a distance greater than the minimum distance.In particular, in the open position of the stripping unit 401, the distance between the upper stripping tool and the lower stripping tool is such that, for example, a gripper carriage 1202 can be moved through the stripping unit 401 in the transport direction T, particularly without contact with the stripping tools. Preferably, the at least one upper and / or lower stripping tool is in contact, preferably operatively connected, to the at least one drive system 1000 and / or can be driven by the at least one drive 1001 of the drive system 1000, at least temporarily, preferably with a cyclic and / or clocked movement. The movement of the at least one upper and lower stripping tool is preferably synchronized and / or adjustable in time. For example, the at least one middle stripping tool is in contact, preferably operatively connected, to the at least one drive system 1000.

[0072] Within the at least one dispensing unit 600, at least a part of the transport system 1200, in particular the chain transport system 1200, is preferably arranged for transporting substrate 02. In particular, at least one guide device 1203 is arranged within the dispensing unit 600, along which the gripper carriages 1201 are preferably guided. Preferably, guide devices 1203 are arranged on both sides in the transverse direction A, limiting the transport path. The transport system 1200 is preferably configured to transport the substrate 02 to a processing position within the at least one dispensing unit 600. In the processing position, the gripper carriage 1201 is preferably arranged such that a gripped substrate 02 can be processed by the at least one cutting tool. It is particularly preferred that it can be processed in such a way that a gripper edge 06 can be separated from the part of the substrate 02 having the at least one recess 03.The part of the substrate 02 having at least one benefit 03, which is also referred to as substrate 02 in the preceding and following text, is then no longer held by the at least one gripper 1202 and is placed on a delivery stack in the opposite direction V.

[0073] After processing the substrate 02 in the processing units 300 and 400, preferably at least after processing in the forming unit 300, the substrate 02 is preferably transported to the delivery unit 600 and deposited there. The at least one gripper carriage 1201 transporting the substrate 02 is preferably arranged in a processing position in the delivery unit 600 and preferably stopped there due to the cyclic movement. By means of the at least one separating tool, a portion of the substrate 02 having at least one recess 03 is preferably separated from the gripper edge 06, particularly preferably by a relative movement between the upper separating tool and the lower separating tool. During the separating process, the at least one, and preferably the at least two, support plates are preferably arranged in the locking position.During the separation process, the substrate 02 is preferably arranged on the at least one, preferably the at least two, support plate, and in particular, it rests on it. The gripper edge 06 is then preferably transported by the gripper carriage 1201 to a further position in which the grippers 1202 open and the gripper edge 06 is, for example, released to a waste device. After the separation process has been completed, i.e., when the at least one gripper carriage 1201 starts moving or is already moving, the at least one, preferably the at least two, support plate is preferably moved from the locking position to the release position, in particular by actuation using the at least one actuator.During the movement from the locking position to the release position, the at least one support plate is preferably adjusted relative to the at least one lateral guide on which it is arranged, either in or against the transverse direction A, such that the distance of the support plate to the lateral guide opposite it with respect to the stacking area increases. The portion of the substrate 02 having the at least one recess 03, hereinafter also referred to as substrate 02, preferably falls downwards against the vertical direction V, preferably at least due to gravity. Preferably, a dispensing stack is formed. The substrate 02 is preferably arranged either as the first substrate 02 of a dispensing stack on the first group of support elements of the at least one non-stop device.Alternatively, the substrate 02 is preferably placed as a further substrate 02 on the uppermost substrate 02 of the already formed delivery stack below. Depending on the operating time, this already formed delivery stack is preferably located either on the at least one support surface of the first group of support elements or on the at least one support surface of the second group of support elements of the at least one support device. During the placement of the substrate 02, particularly on the at least one support surface or on the uppermost substrate 02 of the formed delivery stack, the at least one front edge stop and the at least two lateral guides are preferably fixed, i.e., preferably immovable.During the placement of the substrate 02, particularly on the at least one support surface or on the uppermost substrate 02 of the formed dispensing stack, the at least one trailing edge stop, preferably all trailing edge stops, are set into a vibrating motion by their at least one vibrating drive. Once a required stack height or required number of substrates 02 is reached, the formed dispensing stack is preferably placed on the at least one conveying device and transported from the dispensing unit 600, preferably by means of the at least one conveying device. The maximum height of the dispensing stack is, for example, 400 mm (four hundred millimeters), preferably 380 mm, and more preferably 350 mm.

[0074] The processing machine 01 has at least one transport system 1200 for transporting substrate 02. The at least one transport system 1200 of the processing machine 01 is designed to transport substrate 02 and includes at least one rotating motion element 1204. The transport system 1200 is preferably designed as a chain transport system 1200, more preferably as a chain gripper system 1200. The chain transport system 1200 has at least one, preferably two, rotating chains 1204 as rotating motion elements 1204. Preferably, gripper carriages 1201 are attached to the at least one chain 1204 at a relatively constant distance from each other, preferably on both sides of each chain 1204, which are designed to hold substrate 02. The chain 1204 is guided along the guide device 1203, thereby preferably determining the position of the at least one chain 1204 in the vertical direction V and / or in the transverse direction A and / or in the transport direction T.For example, the at least one chain 1204 has individual chain links. For example, the at least one chain 1204 also has rollers, wheels or the like, which, for example, enable easier movement of the chain 1204 along the guide device 1203.

[0075] The transport system 1200 is preferably connected to drive the at least one rotating motion element 1204 in the chain transport direction K with at least one drive wheel 1205 of the drive system 1000 of the machine tool 01, preferably designed as a sprocket. The at least one drive wheel 1205 is preferably connected to the drive 1001 of the drive system 1000 of the machine tool 01 for driving the at least one machining unit 300; 400 for machining substrate 02, i.e., preferably the main drive 1001 of the machine tool 01.Preferably, the at least one moving element, in particular the at least one chain 1204, is driven by the at least one drive wheel 1205 in a clocked and / or cyclical manner, i.e., depending on the machine cycle time, preferably being accelerated or decelerated, particularly during a machining operation, i.e., especially during the dwell phase, stopped and moved forward for further transport, i.e., especially during the movement phase. In a preferred embodiment, the at least one drive wheel 1205 is arranged at a position where the rotating moving element 1204 changes its chain transport direction K with respect to the spatial directions, in particular by guiding the moving element 1204 around the at least one drive wheel 1205. Thus, the at least one drive wheel 1205 is preferably designed as a first deflection means for deflecting the at least one moving element 1204.Preferably, the at least one drive wheel 1205 is arranged at a transfer position of substrate 02 by the transport system 1200 from an upstream transport device or position, i.e., in particular at the beginning of the transport path of substrate 02 defined by the transport system 1200. Particularly preferably, the at least one drive wheel 1205 is arranged upstream of a processing area of ​​a first processing unit 300; 400, in particular of the at least one forming unit 300. This preferably makes the transmission path of the drive torque from the main drive 1001 to the drive wheel 1205 as short as possible and thus preferably minimizes the susceptibility to errors.

[0076] The direction K in which the at least one moving element 1204, preferably the at least one chain 1204, is moved during operation is the chain transport direction K. The chain transport direction K is thus parallel to the transport direction T in a section where a substrate 02 is guided, i.e., along the transport path of substrate 02. In sections of the guide outside the transport path of substrate 02, the chain transport direction K, due to its design as a circulating moving element 1204, in particular as a chain 1204, preferably deviates from the transport direction T, is, for example, opposite to it, or has a vector with a non-zero vertical component.

[0077] The at least one guide device 1203 preferably has at least one guide element 1229, 1231, or 1232. Preferably, each of these is designed as at least one guide rail. The at least one guide element 1229, 1231, or 1232 preferably limits the space in which the at least one moving element 1204 can move. Preferably, the at least one guide device 1203 only allows movement of the at least one moving element 1204 in and against the chain transport direction K. Preferably, at least one, and preferably several, guide elements 1232, which guide the at least one moving element 1204 in the area of ​​the transport path of substrate 02, are aligned parallel to the transport path, preferably horizontally.For example, at least one, preferably several, guide element 1232, which guides the at least one moving means 1204 in the area outside the transport path of substrate 02, preferably guiding the at least one chain 1204 from a rear section to a front section of the processing machine 01, is aligned parallel to the transport path, preferably horizontally. Preferably, at least one, preferably several, guide element 1232, which induces a change in the direction of the chain transport direction K, has a non-zero vertical component and particularly preferably has an arc-shaped profile for guiding the moving means 1204.The at least one guide device 1203, preferably its at least one guide element 1229; 1231; 1232, particularly preferably at least two, further preferably a plurality of the guide elements 1229; 1231; 1232 of the at least one guide device 1203, are in a preferred embodiment designed to be fixed in position relative to a housing or a holder 1233 of the machine tool 01, preferably fixed to the housing or holder 1233 of the machine tool 01, for example by screwing.

[0078] In particular, for adjusting the tension of the rotating conveying element 1204, especially the chain tension of the at least one chain 1204, the transport system 1200 preferably has at least one tensioning device 1206. In the preceding and following, tension refers in particular to mechanical stress, i.e., preferably a measure of the internal stress of the body as a result of its load. The at least one tensioning device 1206 has at least one tensioning element 1207 for tensioning the at least one rotating conveying element 1204, especially the at least one chain 1204. Preferably, the transport system 1200 has one tensioning device 1206 for each chain 1204, i.e., preferably two. These preferably adjust the chain tension of the respective chain 1204 independently of one another. The chain tension is thus preferably adjusted individually for each chain 1204 of the chain transport system 1200.

[0079] The at least one clamping device 1206 is preferably arranged at a position where the at least one moving element 1204 changes its chain transport direction K with respect to the spatial directions, preferably by guiding the chain 1204 around the at least one clamping device 1207. Thus, the at least one clamping device 1207 is preferably designed as a second deflecting element for deflecting the at least one moving element 1204. In a preferred embodiment, the at least one clamping device 1206 is arranged in the delivery unit 600 of the processing machine 01, particularly preferably after the transport path of the substrate 02.

[0080] In a preferred embodiment, the at least one clamping device 1207 has an elastic surface, particularly in the form of a rubber coating, in the area of ​​its surface which is designed to guide the at least one movement device 1204. Advantageously, this increases the effect of the operative contact between the movement device 1204 and the clamping device 1207.

[0081] The at least one clamping device 1207 is preferably rotatably arranged about an axis of rotation S with a maximum rotation angle β of less than 360°. The axis of rotation S is preferably parallel to the transverse direction A. Preferably, the axis of rotation is singular, meaning that the at least one clamping device 1207 is mapped onto itself by a rotation of 360°. In particular, the maximum rotation angle β is less than or equal to the rotation angle of a circular sector with the axis of rotation S as its center, wherein the arc of the circular sector is formed by a maximum extent of a surface of a first contact area 1208 or by a maximum extent of a surface of a second contact area 1209. Particularly preferably, the maximum rotation angle β of the at least one clamping device 1207 about its axis of rotation S is a maximum of 30°, more preferably a maximum of 25°, more preferably a maximum of 20°, and more preferably a maximum of 16°.Preferably additionally or alternatively, the maximum rotation angle β of the at least one clamping device 1207 about its axis of rotation S is at least 0.1°, more preferably at least 1°, more preferably at least 2°, even more preferably at least 10°, and even more preferably at least 15°. In particular, the axis of rotation S thus describes an axis about which the at least one clamping device 1207 is pivoted.

[0082] For example, the at least one clamping device 1206 has at least one stop 1213, preferably a mechanical stop 1213, in particular a stop, to limit the rotation. Preferably, at least one stop 1213 is arranged in and / or against the chain transport direction K, limiting the rotation. Preferably, the at least one stop 1213 ensures that the maximum rotation angle β remains within a permissible range. Preferably, the stop 1213 prevents a collision of the machine parts in the event of overload or failure of individual components of the machine tool 01.

[0083] The at least one clamping device 1207 is preferably designed to rotate in or against the chain transport direction K, depending on the existing tension of the at least one movement means 1204, preferably the existing chain tension of the at least one chain 1204, in particular by a tension-dependent rotation angle γ. It is especially preferred that the at least one clamping device 1207 rotates in the chain transport direction K in order to increase the tension. The tension-dependent rotation angle γ preferably describes a phase shift in the positioning of the at least one clamping device 1207, in particular independent of any existing machine cycle time.

[0084] Preferably, or additionally or alternatively, the at least one clamping device 1207 is synchronized to a machine cycle, i.e., preferably rotated in and against the chain transport direction K depending on a given machine cycle, in particular by a rotation angle δ, also called the cycle rotation angle δ. The cycle rotation angle δ preferably describes a cycle-dependent positioning of the at least one clamping device 1207.

[0085] The stress-dependent rotation angle γ and the indexing rotation angle δ are preferably each smaller than the maximum rotation angle β. More preferably, the sum of the stress-dependent rotation angle γ and the indexing rotation angle δ is at most as large as the maximum rotation angle β. Preferably, the stress-dependent rotation angle γ of the at least one clamping device 1207 about the axis of rotation S is at least 0.1°, more preferably at least 1°, even more preferably at least 2°, and / or at most 30°, more preferably at most 25°, more preferably at most 20°, more preferably at most 16°, more preferably at most 10°, and even more preferably at most 5°. Preferably the indexing rotation angle δ of the at least one clamping device 1207 about the axis of rotation S is at least 0.1°, more preferably at least 1°, even more preferably at least 2°, and / or a maximum of 30°, preferably a maximum of 25°, more preferably a maximum of 20°, more preferably a maximum of 16°, °, more preferably a maximum of 10°, and even more preferably a maximum of 5°.

[0086] The at least one clamping device 1207 is preferably mounted so as to be rotatable about the axis of rotation S. Preferably, the at least one clamping device 1207, in particular its axis of rotation S, is mounted in a positionally fixed manner. Preferably, the at least one clamping device 1207, in particular its axis of rotation S, is designed to be positionally fixed relative to a housing or holder 1233 of the machine tool 01. Advantageously, the positionally fixed mounting stabilizes the guide of the movement element 1204, reduces vibrations in particular, and simplifies the design of the clamping device 1206.

[0087] The at least one clamping device 1207 preferably has a surface that guides the rotating drive element 1204. For example, this surface is rail-shaped and / or has at least one sliding surface for the at least one drive element 1204 to slide along the surface. Preferably, the at least one clamping device 1207 has a continuous surface in a region designed for guiding the at least one drive element 1204, preferably between a first contact region 1208 and a second contact region 1209. Particularly preferably, the at least one clamping device 1207 has a curved surface in at least one region designed for guiding the at least one drive element 1204.Preferably, the at least one moving element 1204 is guided continuously, i.e., preferably without interruptions, between a first contact point 1211 and a second contact point 1209 by the at least one clamping element 1207, particularly in contact with it. The surface of the at least one clamping element 1207 is particularly preferably designed to be continuously differentiable in the area for guiding the at least one moving element 1204. In a preferred embodiment, the at least one clamping element 1207 is designed as part of a wheel.

[0088] At a first contact point 1211, there is preferably a first contact with respect to the chain transport direction K between the at least one moving means 1204, particularly if it is present, and the at least one clamping means 1207. At a second contact point 1212, there is preferably a final contact with respect to the chain transport direction K between the at least one moving means 1204, particularly if it is present, and the at least one clamping means 1207. The contact point 1211; 1212 is formed as a point in two dimensions, preferably in the transverse direction A. In three dimensions, the contact point 1211; 1212 is preferably formed as a line, the line preferably being arranged orthogonally to the chain transport direction K on the surface of the at least one clamping means 1207, preferably directed in the transverse direction A.The contact points 1211; 1212 preferably describe positions in space in the preceding and following sections, particularly independent of the actual point on the surface of the moving means 1204 and / or the clamping means 1207 that they form. Preferably, the surface of the moving means 1204 and / or the surface of the clamping means 1207 moves relative to the contact point 1211; 1212. The position of the contact between the moving means 1204, preferably chain 1204, in particular its chain links and / or rollers and / or wheels, and the clamping means 1207 and / or between the moving means 1204 and the guide device 1203 preferably describes the point at which they are in operative contact, in particular in touch. Between the first contact point 1211 and the second contact point 1212, the at least one moving means 1204 is particularly preferably continuously in operative contact, preferably in direct contact, with the at least one clamping means 1207.

[0089] In a preferred embodiment, the first contact point 1211 and the second contact point 1212 are fixed in position relative to a housing and / or a holder 1233 of the machine tool 01. The first contact point 1211 and the second contact point 1212 are preferably arranged in a fixed position relative to a housing and / or a holder 1233 of the machine tool 01. Preferably, the first and second contact points 1211 and 1212 thus have, in particular at least substantially, constant spatial coordinates, especially independent of a rotational movement of the at least one clamping device 1207. Advantageously, the fixed contact points 1211 and 1212 facilitate a change in the guidance of the rotating motion element 1204 between the clamping device 1206 and the guide device 1203. Advantageously, the fixed contact points 1211 and 1212 reduce the number of moving components required for the transport system 1200.

[0090] The first contact point 1211 has a first distance R1 to the axis of rotation S, and the second contact point 1212 has a second distance R2 to the axis of rotation S. The first contact point 1211, the second contact point 1212, and the axis of rotation S are arranged relative to each other in a triangle, preferably viewed from the side, i.e., in the transverse direction A. The triangle is preferably arranged in a two-dimensional projection in a plane spanned by the vertical direction V and the transport direction T. The first distance R1 and the second distance R2 are different from each other. Thus, the contact points 1211 and 1212 preferably form an asymmetrical triangle with the axis of rotation S, i.e., a triangle whose three sides are of different lengths. Particularly preferably, the surface of the clamping device 1207, which guides the at least one means of movement 1204, forms an eccentrically mounted circular arc.The different distances R1; R2 of the contact points 1211; 1212 to the axis of rotation S advantageously increase or decrease the tension of the rotating means of motion 1204 relative to a tension before rotation during a rotational movement, preferably in particular by changing a contact length I11; I11'; I12; I21'; I21; I21'; I22; I22' of the rotating means of motion 1204 to the at least one clamping means 1027.

[0091] The first contact point 1211 and the second contact point 1212 are preferably spaced apart by a further distance H. This further distance H is preferably greater than the first distance R1. Additionally, this further distance H is preferably greater than the second distance R2. The axis of rotation S is therefore located closer to the contact points 1211 and 1212 than they are to each other. Preferably, the axis of rotation S is arranged within the clamping device 1207. In a particularly preferred embodiment, the axis of rotation S is arranged eccentrically within the clamping device 1207 relative to a center of mass of the at least one clamping device 1207. The at least one clamping device 1207 is preferably rotated eccentrically about the axis of rotation S arranged within the clamping device 1207 relative to its center of mass. Advantageously, vibrations are reduced by the arrangement of the axis of rotation S.

[0092] In the preceding and following text, the distance between two reference points refers to the length of the shortest connection between those reference points. Similarly, the distance between a point or a first axis and a second axis describes the length of the shortest connection from the point or first axis to the second axis. This shortest connection is perpendicular to the second axis, and in the case of the first axis, also perpendicular to the first axis.

[0093] In a preferred embodiment, the first distance R1 of the first contact point 1211 to the axis of rotation S is smaller than the second distance R2 of the second contact point 1212 to the axis of rotation S. This preferred design advantageously increases the contact length I21; I21'; I22; I22' of the second contact area 1209 and decreases the contact length I11; I11'; I12; I21' of the first contact area 1208 when the at least one clamping device 1207 rotates in a direction opposite to the chain transport direction K. Advantageously, rotating the at least one clamping device 1207 in a direction opposite to the chain transport direction K increases the tension of the moving element 1204 relative to the previously existing tension. Advantageously, this prevents self-locking of the system consisting of the moving element 1204 and the clamping device 1206, which can occur when the clamping device 1206 acts in the opposite direction.For example, the first distance R1 is at least 300 mm, preferably at least 350 mm, more preferably at least 400 mm, and / or a maximum of 500 mm, more preferably a maximum of 450 mm, more preferably a maximum of 420 mm. For example, the second distance R2 is at least 450 mm, preferably at least 480 mm, more preferably at least 500 mm, more preferably at least 510 mm, and / or a maximum of 600 mm, more preferably a maximum of 550 mm, more preferably a maximum of 530 mm. Preferably, the distances R1 and R2 are chosen to be as large as possible, for example, 420 mm for the first distance R1 and 510 mm for the second distance R2, which advantageously makes it possible to reduce the pressure on the surface of the clamping device 1207 by the movement means 1204.

[0094] The interior angle α of the triangle formed by the contact points 1211 and 1212 with the axis of rotation S is the angle α. Thus, the angle α is the angle rotated about the axis of rotation S from the first distance R1 of the first contact point 1211 to the axis of rotation S to the second distance R2 of the second contact point 1212 to the axis of rotation S. Preferably, the interior angle α is obtuse; the contact points 1211 and 1212 with the axis of rotation S preferably form an obtuse triangle. Particularly preferably, the interior angle α is at least 90°, more preferably at least 100°, more preferably 120°, and / or less than 180°, more preferably at most 160°, and more preferably at most 140°. The angle α rotated about the axis of rotation S from the first distance R1 of the first contact point 1211 to the axis of rotation S to the second distance R2 of the second contact point 1212 to the axis of rotation S is preferably independent of a rotation of the at least one clamping device 1207 about its axis of rotation S.In particular, the internal angle α remains unchanged during a rotational movement of the at least one clamping device 1207, i.e., in a first state and in a second state of the at least one clamping device 1207. Advantageously, the spatial coordinates of the first and second contact points 1211 and 1212 are fixed. The at least one clamping device 1207 is preferably enclosed by the at least one movement means 1204 from the first contact point 1211 to the second contact point 1212. Thus, the internal angle α at the axis of rotation S is preferably the angle of enclosure with which the at least one clamping device 1207 is enclosed by the at least one movement means 1204.

[0095] The at least one clamping device 1207 preferably has at least one, in particular at least two, and more preferably at least three contact areas 1208; 1209; 1210. A contact area 1208; 1209; 1210 has at least one area point B11; B11'; B12; B12'; B21; B21'; B22; B22'; B10; B14; B20; B24. Preferably, a contact area 1208; 1209; 1210 has a plurality of area points B11; B11'; B12; B12'; B21; B21'; B22; B22'; B10; B14; B20; B24, arranged one after the other in the chain transport direction K, which can come into operative contact with the at least one movement means 1204 or do come into operative contact. Along the chain transport direction K, the at least one moving element 1204, if present, is configured to first come into effective contact with a first contact area 1208. The last contact area 1209, with which the at least one moving element 1204 comes into effective contact if present, is designated as the second contact area 1209.Along the chain transport direction K between the first and second contact areas 1208; 1209, at least one third contact area 1210 is preferably arranged. The contact area 1208; 1209; 1210 preferably has a first possible area point B10; B20 and a last possible area point B14; B24 of all area points B11; B11'; B12; B12'; B21; B21'; B22; B22'; B10; B14; B20; B24 of the respective contact area 1208; 1209; 1210 with respect to the chain transport direction K, which can preferably come into operative contact with the at least one means of movement 1204. The maximum rotation angle β preferably defines the maximum arc length between the first possible area point B10; B20 and the last area point B14; B24 of the first or second contact area 1208; 1209 fixed.

[0096] In the preceding and following sections, a region point B11; B11'; B12; B12'; B21; B21'; B22; B22'; B10; B14; B20; B24 preferably describes a point on the surface of the at least one clamping device 1207 within the relevant contact area 1208; 1209; 1210. In the preceding and following sections, region points B11; B11'; B12; B12'; B21; B21'; B22; B22'; B10; B14; B20; B24, arranged one after the other, are preferably distinguished, at least with respect to the chain transport direction K. Preferably, in a three-dimensional view, orthogonal to the chain transport direction K, and in particular in the transverse direction A, region points B11; B11'; B12; B12'; B21; B21'; B22; B22'; B10; B14; B20; B24 a range line.Thus, the area points B11; B11'; B12; B12'; B21; B21'; B22; B22'; B10; B14; B20; B24, arranged one after the other in the chain transport direction K, also include the area lines arranged orthogonally to the chain transport direction K.

[0097] The at least one clamping device 1207 preferably has a contact area B11; B11'; B12; B12' corresponding to the first contact point 1211, which changes by rotating the at least one clamping device 1207 within the first contact area 1208. Additionally, the at least one clamping device 1207 preferably has a contact area B21; B21'; B22; B22' corresponding to the second contact point 1212, which changes by rotating the at least one clamping device 1207 within the second contact area 1209.

[0098] The contact points B11; B11'; B12; B12'; B10; B14 of the first contact area 1208 preferably have the same distance R1 to the axis of rotation S relative to each other. The contact points B21; B21'; B22; B22'; B20; B24 of the second contact area 1209 preferably have the same distance R2 to the axis of rotation S relative to each other. Advantageously, this allows the at least one clamping device 1207 to be rotated about its axis of rotation S with a rotation angle γ; δ less than or equal to the maximum rotation angle β, without the distance to the axis of rotation S of the now occupied contact point B11; B11'; B12; B12'; B10; B14; B21; B21'; B22; B22'; B20; B24 changing from the distance of the previous contact point B11; B11'; B12; B12'; B10; B14; B21; B21'; B22; B22'; B20; B24 are distinguished. Advantageously, the contact points 1211; 1212 remain in the same position despite rotation of the at least one clamping device 1207.

[0099] Depending on the existing tension of the at least one motion element 1204, the at least one clamping element 1207 preferably has a first state, more preferably describing a first positioning, or at least a second state, more preferably describing a positioning different from the first positioning. Preferably, a state different from a previously assumed state is assumed in order to adjust, or preferably increase, the tension of the motion element 1204 when it changes, in particular decreases. Preferably, the change of state adjusts the tension of the motion element 1204 to a target value or target range. In particular, the change of state counteracts a decrease in the tension of the at least one motion element 1204 due to wear and / or aging.

[0100] The area points B11, B12, B21, B22 corresponding to the contact points 1211; 1212 in the first state are preferably arranged rotated about the axis of rotation S relative to the area points B11', B12', B21', B22' corresponding to the contact points 1211; 1212 in the second state by a stress-dependent rotation angle γ that is smaller than the maximum rotation angle β. Thus, the at least one clamping device 1207 is preferably arranged rotated about the axis of rotation S relative to the first state by the stress-dependent rotation angle γ in the second state relative to the first state. These area points B11, B12, B21, B22, B11', B12', B21', B22' therefore preferably each describe a point on the surface of the at least one clamping device 1207 at which the first or last contact with the moving means 1204 exists in this state.In particular, the respective contact points B11; B11'; B12; B12' of the first contact area 1208 and the respective contact points B21; B21'; B22; B22' of the second contact area 1209, which in the assumed state correspond to the respective contact points 1211; 1212, are arranged rotated about the pivot point S with an internal angle α to each other. Thus, the contact points 1211; 1212 preferably remain in the same position despite a change of state.

[0101] The at least one clamping device 1207 preferably has a first positioning or at least a second positioning, synchronized with a machine cycle. In particular, the at least one clamping device 1207 has a first positioning during a first machine cycle, for example, during a machine cycle of the movement phase, and a further positioning different from the first during a subsequent machine cycle, for example, during a machine cycle of the dwell phase. Preferably, the positioning of the clamping device 1207 is coupled to the machine cycle of the machine tool 01. Preferably, the change in positioning compensates for a change in the tension of the movement device 1204 due to machining operations of the machine tool 01.Particularly preferably, the changing of the positioning counteracts an increase in the tension of the at least one motion element 1204 due to deflections of the motion element 1204 during a machining operation of the machine tool 01. Particularly preferably, the tension of the motion element 1204 is adjusted to a target value or target range.

[0102] The area points B11; B11'; B21; B21' corresponding to contact points 1211; 1212 are preferably arranged in a clocked manner relative to a first machine cycle, and relative to the area points B12; B12'; B22; B22' corresponding to contact points 1211; 1212 of a second machine cycle, with a clock rotation angle δ that is smaller than the maximum rotation angle β, and are arranged rotated about the axis of rotation S. The clock rotation angle δ is particularly preferably the same for successive machine cycles. The at least one clamping device 1207 is preferably arranged in the second machine cycle, rotated about the axis of rotation S relative to the first machine cycle with the clock rotation angle δ.In particular, the respective contact points B11; B11'; B12; B12' of the first contact area 1208 and the respective contact points B21; B21'; B22; B22' of the second contact area 1209, which correspond to the respective contact points 1211; 1212 in the relevant machine cycle, are arranged rotated about the pivot point S with an internal angle α relative to each other. Thus, the contact points 1211; 1212 preferably remain in the same position despite the adjustment of the at least one clamping device 1207.

[0103] The contact points B11; B11'; B12; B12'; B10; B14; B21; B21'; B22; B22'; B20; B24 are preferably arranged in an arc shape within the first contact area 1208 and / or within the second contact area 1209 in the chain transport direction K. Preferably, the surfaces of the first and / or second contact area 1208; 1209, and preferably also of the at least one third contact area 1210, are preferably arc-shaped. Preferably, the surfaces of the contact areas 1208; 1209; 1210 within their respective contact areas 1208; 1209; 1210 are continuously differentiable, in particular forming a polynomial chain. Further preferably, the surfaces of the at least three contact areas 1208; 1209; 1210 are continuously differentiable with each other, in particular forming a common polynomial chain. Particularly preferably, the third region 1210 has at least one region point which has a third distance to the axis of rotation S.The magnitude of the third distance is greater than the smaller distance between R1 and R2 of the first or second contact area 1208 or 1209, and smaller than the larger distance between R1 and R2 of the first or second contact area 1208 or 1209. In other words, the distance between the first and second contact area 1208 or 1209 increases from the smaller to the larger distance R1 and R2. Advantageously, the arc-shaped design and / or arrangement allows for better guidance of the moving element 1204. In particular, the occurrence of a blockage of the moving element 1204 during its movement is advantageously reduced. The at least one third area, especially its preferred arc-shaped design, advantageously supports the guidance of the moving element 1204 between the first and second contact area 1208 or 1209 and / or advantageously minimizes any acceleration and / or force acting on the moving element 1204.

[0104] The first and / or second contact area 1208; 1209 preferably each has a surface length in the chain transport direction K for effective contact with the at least one moving means 1204, which corresponds to the length of a circular arc of a circular sector, wherein the radius of this sector corresponds to the distance R1; R2 of the respective first and last possible area points B10; B14; B20; B24 to the axis of rotation S, and its angle corresponds to the maximum angle of rotation β. Preferably, the first contact area 1208 and the second contact area 1209, and more preferably additionally the at least one third contact area 1210, each form a circular sector around the axis of rotation S. For example, the circular sector formed by the first contact area 1208, by the second contact area 1209, or by the third contact area 1210 is each completely filled by material of the at least one clamping means 1207.In an alternative preferred embodiment, at least one circular sector of the circular sectors is free of material in at least one area, in particular in an area of ​​the circular sector that differs from the surface of the contact area 1208; 1209; 1210 for guiding the at least one movement means 1204. The surface of the contact area 1208; 1209; 1210 for guiding the at least one movement means 1204 is preferably connected to the axis of rotation S via at least one web. Advantageously, this reduces the weight of the at least one clamping means 1207.

[0105] The surface of the at least one clamping device 1207 preferably has a contact area with a contact length I11; I11'; I12; I21' within the first contact area 1208 and with a contact length I21; I21'; I22; I22' within the second contact area 1209 for contact with the at least one movement device 1204. The contact length I11; I11'; I12; I21' is preferably, within the first contact area 1208, the length of the circular arc from the area point B11; B11'; B12; B12', which corresponds to the first contact point 1211, to the last area point B14 of the first contact area 1208, preferably having the same distance R1. The contact length I21; I21'; I22; I22' is preferably within the second contact area 1209 the length of the circular arc from the first possible area point B20 of the second contact area 1209 to the area point B21; B21'; B22; B22', which corresponds to the second contact point 1212.

[0106] The contact lengths I11; I11'; I12; I21' of the first contact area 1208 and the contact lengths I21; I21'; I22; I22' of the second contact area 1209 are preferably different in the first state from the second state. When switching from the first state to the second state or vice versa, the contact lengths I11; I11'; I12; I12' within the first contact area 1208 are preferably changed as a function of the voltage-dependent rotation angle γ from a contact length I11; I12 of the first state to a contact length I11'; I12' of the second state or vice versa.Additionally, preferably within the second contact area 1209, the contact length I21; I21'; I22; I22' is changed as a function of the same voltage-dependent rotation angle γ from a contact length I21; I22 of the first state to a contact length I21'; I22' of the second state, wherein the change in the contact length I11; I11'; I12; I12' of the first contact area 1208 is inversely proportional to the change in the contact length I21; I21'; I22; I22' of the second contact area 1209. In other words, preferably the contact length I21; I21'; I22; I22' of the second contact area 1209 increases as a function of the voltage-dependent rotation angle γ, and the contact length I11; I11'; I12; I12' of the first contact area 1208 as a function of the same voltage-dependent rotation angle γ or vice versa.

[0107] Additionally or alternatively, the contact length I11; I11'; I12; I21' of the first contact area 1208 and the contact length I21; I21'; I22; I22' of the second contact area 1209 are preferably different during the first machine cycle compared to the second machine cycle. When adjusting the positioning from the first machine cycle to the second machine cycle or vice versa, the contact length I11; I11'; I12; I12' within the first contact area 1208 is preferably changed as a function of the cycle rotation angle δ from a contact length I11; I11' of the first machine cycle to a contact length I12; I12' of the second machine cycle or vice versa.Additionally, preferably within the second contact area 1209, the contact length I21; I21'; I22; I22' is changed as a function of the same clock rotation angle δ from a contact length I21; I21' of the first machine cycle to a contact length I22; I22' of the second machine cycle, wherein the change in the contact length I11; I11'; I12; I12' of the first contact area 1208 is inversely proportional to the change in the contact length I21; I21'; I22; I22' of the second contact area 1209. In other words, preferably the contact length I21; I21'; I22; I22' of the second contact area 1209 increases as a function of the clock rotation angle δ, and the contact length I11; I11'; I12; I12' of the first contact area 1208 decreases as a function of the same clock rotation angle δ, or vice versa.

[0108] In a preferred embodiment of the transport system 1200, the at least one guide device 1203 has at least one guide element 1229 for guiding the at least one moving element 1204, in particular the at least one circulating chain 1204 of the chain transport system 1200, which is arranged upstream of the at least one tensioning device 1206, preferably directly upstream. Preferably additionally or alternatively, the at least one guide device 1203 has at least one guide element 1231 for guiding the at least one moving element 1204, in particular the at least one circulating chain 1204 of the chain transport system 1200, which is arranged downstream of the at least one tensioning device 1206, preferably directly downstream.

[0109] The guide element 1229 upstream of the at least one clamping device 1207 and / or the guide element 1231 downstream of the at least one clamping device 1207 are preferably each arranged in operative connection with the at least one clamping device 1207. In a preferred embodiment, the at least one clamping device 1207 has a guide groove 1214; 1216 along its surface, preferably at least within a region of its surface which comes into contact with the respective guide element 1229; 1231 depending on the stress-dependent rotation angle γ of the clamping device 1207, into which a correspondingly shaped region of the respective guide element 1229; 1231 can engage or does engage. Thus, the at least one clamping device 1207 preferably has a first guide groove 1214 for operative connection with the upstream guide element 1229 and / or a second guide groove 1216 for operative connection with the downstream guide element 1231.The surface of the at least one upstream guide element 1229, which comes into operative contact with the at least one clamping device 1207, is preferably designed as a tangent to the surface of the first contact area 1208. The surface of the at least one downstream guide element 1231, which comes into operative contact with the at least one clamping device 1207, is preferably designed as a tangent to the surface of the second contact area 1209. Advantageously, this ensures the maintenance of the operative connection, and thus reliable guidance of the at least one movement element 1204, even during a rotational movement of the at least one clamping device 1207 about its axis of rotation S.

[0110] The guide element 1229 of the at least one clamping device 1206, in particular its at least one clamping means 1207, preferably directly upstream, and / or the guide element 1231 of the transport system 1200 for guiding the at least one rotating motion element 1204, is preferably each configured to be positionally fixed relative to a housing or a holder 1233 of the machine tool 01. In particular, the at least one upstream and / or downstream guide element 1229; 1231 is arranged in a constant position independent of the positioning of the at least one clamping means 1207.Advantageously, the fixed position of the upstream and / or downstream guide element 1229; 1231 facilitates the transfer of the rotating motion element 1204 between the clamping device 1206 and the guide device 1203. The guide element 1229 upstream of the at least one clamping device 1206 and / or the guide element 1231 downstream of the at least one clamping device 1206 of the transport system 1200 for guiding the at least one rotating motion element 1204 preferably remains fixed in its position relative to a housing or a holder 1233 of the machine tool 01 during rotation of the at least one clamping device 1207 about its axis of rotation S. Advantageously, the fixed position of the upstream and / or downstream guide element 1229; 1231 reduces the number of movable components required in the transport system 1200.

[0111] For example, further guide elements 1232 are arranged along the circumferential path of the at least one moving element 1204, in particular the chain 1204, which are preferably designed to be fixed in position. For example, additionally or alternatively, at least one further guide element 1232, which guides the at least one chain 1204 along the transport path of substrate 02 and is preferably spaced apart from the at least one clamping device 1206, is designed to pivot relative to the transport path of substrate 02, i.e., to be changeable in its position. This is the case, for example, at the output of the forming unit 300 and / or at the output of the stripping unit 400, for example, to react to a movement of the tool. Preferably, the guide element 1232 pivots about a pivot axis that is orthogonal to the transport direction T.The pivot axis is located, for example, at an input of the forming unit 300 and / or at the input of the stripping unit 400.

[0112] For example, at least one further device of the processing machine 01 is mechanically connected to or arranged on the at least one clamping device 1206. An example of this is an opener of a gripper carriage 1201, by which, for example, the grippers 1202 of the gripper carriage 1201 are opened to release the gripper edge 06. Preferably, the positioning of the at least one device is independent of the adjustment of the clamping of the at least one moving means 1204; thus, it is preferably arranged in a fixed position.

[0113] The at least one clamping device 1206 preferably has at least one adjusting system 1219, in particular for adjusting the at least one clamping element 1206. The design of the adjusting system 1219 is advantageously simplified, in particular by at least one adjusting element 1217 and / or at least one connecting device 1220.

Advantageously, a reduction in tension due to an elongation of the at least one motion element 1204, for example due to aging and / or wear, is compensated for.

[0115] In a particularly preferred embodiment, the at least one positioning system 1219 is configured, in addition to or as an alternative to the tension-dependent adjustment, to effect an adjustment of the at least one clamping device 1207 that is synchronized with a machine cycle, in particular the adjustment of the at least one clamping device 1207 from its position during the first machine cycle to its position during the second machine cycle or vice versa. The synchronized adjustment thus preferably occurs as a function of a given machine cycle. In particular, the at least one clamping device 1207 is adjusted from a position during the dwell phase of the machine cycle to a different position during the movement phase of the machine cycle. Advantageously, the movement of the at least one clamping device 1207 compensates for cycle-related fluctuations in the tension of the rotating motion element 1204.

[0116] In a preferred embodiment, a mechanical, particularly preferably rigid, or electronic coupling to the drive system 1000 of the machine tool 01, preferably to the drive 1001, is configured to effect the clocked adjustment, preferably also described as periodic and / or cyclic adjustment.

[0117] For electronic coupling, a drive means, for example an electric motor or an actuating cylinder 1217, is particularly preferably the at least one actuating cylinder 1217, electronically coupled to the machine cycle by a control device 1101.

[0118] In a preferred embodiment, the mechanical coupling is achieved via at least one connecting device 1220 to the at least one drive 1001 of the drive system 1000 of the machine tool 01. The drive 1001, in particular the drive element of the drive 1001, is preferably configured to drive the movement of the at least one machining unit 300; 400 for machining substrate 02. The mechanical coupling to the main drive 1001 of the machine tool 01 is particularly preferred. For example, the mechanical coupling forms a positive drive connection. Advantageously, a separate control system for adjustment is not required. The reaction inertia of the connecting device 1220 is advantageously minimized.

The at least one eccentric 1224; 1227 preferably converts the motion of a driving part relative to the motion of at least one output part, in particular its direction. Advantageously, the required installation space of the connecting device 1220 is reduced by the use of the at least one eccentric. Advantageously, the magnitude of the clocked adjustment, in particular the magnitude of the clocked rotation angle δ, is set by the at least one eccentric 1224; 1227.

[0121] The at least one positioning system 1219 preferably comprises at least one positioning element 1217. The at least one positioning element 1217 is preferably designed as a positioning cylinder 1217, particularly preferably as a hydraulic cylinder 1217, or alternatively as a pneumatic cylinder. For example, alternatively, the at least one positioning element 1217 is designed as a linear actuator, preferably an electric motor, or as a drive in combination with at least one pulley system. The preferred design as a positioning cylinder 1217, particularly preferably a hydraulic cylinder 1217, especially through the use of a hydraulic pressure medium, advantageously results in particularly short response times and extremely precise adjustments.Compared to a pneumatic cylinder, the hydraulic cylinder 1217 offers the particular advantage of an incompressible or only minimally compressible pressure medium, which advantageously results in more precise adjustment and faster achievement of the set value of the controlled variable. A spring instead of the preferred actuating medium 1217, for example, would not be capable of regulation and would, for instance, adversely lead to further vibrations in the system.

[0122] The at least one actuating means 1217, in particular the at least one actuating cylinder 1217, preferably has a piston 1218 which is linearly movable.

[0126] The at least one pressure sensor preferably detects the pressure prevailing in a cylinder of the actuating device 1217, which is preferably designed as an actuating cylinder 1217, preferably the pressure generated by a hydraulic pressure medium. If this deviates from a setpoint value, the quantity of pressure medium is preferably adjusted, in particular, additional pressure medium is supplied to the cylinder if necessary. The piston 1218 of the actuating device 1217 is then preferably adjusted linearly.

[0127] The at least one force sensor preferably detects a force generated by the at least one actuating means 1217. If this at least one measured value deviates from a setpoint, the quantity of pressure medium is preferably adjusted. This is preferably done by linearly adjusting the piston 1218 of the actuating means 1217.

[0128] The at least one position sensor preferably detects the position of the piston 1218 of the at least one actuating device 1217, or it detects the position of the at least one clamping device 1207 relative to the axis of rotation S, i.e., in particular its rotational position. If the position deviates from a target position, the piston 1218 of the actuating device 1217 is preferably adjusted linearly, in particular by adjusting the quantity of the pressure medium.

[0129] The at least one length sensor preferably detects a stroke of the piston 1218 of the at least one actuating means 1217. If the stroke deviates from a setpoint value, the piston 1218 of the actuating means 1217 is preferably adjusted linearly, in particular by adjusting the quantity of the pressure medium.

[0130] The at least one control device 1101 is preferably configured to adjust the at least one clamping device 1207 based on a force and / or a quantity proportional to the force, depending on the existing tension of the at least one rotating motion element 1204, and / or to a position-based adjustment. The at least one actuating device 1217 is particularly preferably configured to be controlled at at least one time based on a force and / or a quantity proportional to the force, preferably pressure-based, and more preferably based on the pressure of a pressure medium within the actuating cylinder 1217. The at least one actuating device 1217 is particularly preferably pressure-controlled at least temporarily. During machining operations, the at least one actuating device 1217 is preferably force-based and / or controlled based on a quantity proportional to the force, and more preferably pressure-controlled.Preferably, additionally or alternatively, the at least one actuating means 1217 is configured to be position-based at at least one time, preferably based on the position of a component, in particular the piston 1218, of the at least one actuating means 1217 and / or based on the stroke length of the piston 1218. For example, position control is performed when a sample sheet is to be ejected from the processing machine 01. Preferably, additionally or alternatively, position control is also performed, for example, to reduce the tension of the moving means 1204, particularly during the dwell phase of the machine cycle.For example, the position control of the at least one actuating device 1217 is selected, in particular at least for the control of the clocked adjustment, if an electronic coupling to the drive system 1000 is present, in particular if the connecting device 1220 is separated or decoupled from the drive means of the machine tool 01, in particular its main drive 1001, or if there is no mechanical connection to the drive means of the machine tool 01, in particular its main drive 1001.

[0131] The at least one positioning system 1219 is preferably configured such that the controlled variable of the at least one actuator 1217 fluctuates around a setpoint within a tolerance range. In particular, the at least one control device 1101 is configured to control the at least one positioning system 1219 such that the controlled variable of the at least one actuator 1217 fluctuates around the setpoint within the tolerance range. Preferably, a continuously repeating control loop is present with, more preferably, a controlled variable that increases and decreases within the tolerance range. The tolerance range is preferably a maximum of 10% of the setpoint, more preferably a maximum of 5%, and more preferably a maximum of 3.5%. The setpoint is preferably a constant value, particularly preferably independent of the current machine cycle and / or independent of any extension of the at least one motion element 1204.The controlled variable, preferably the force and / or the quantity proportional to the force, preferably the pressure, and / or the position, is preferably proportional to the resultant force, in particular exerted on the at least one clamping device 1207 and thereby on the at least one rotating motion element 1204. Preferably, the resultant force of the at least one positioning system 1219 fluctuates within a tolerance range around a value that is proportional to the tolerance range or the setpoint of the controlled variable. The resultant force is preferably the force that causes the adjustment of the clamping device 1207.

[0132] The at least one adjusting system 1219 is preferably located at a connection point P on the at least one clamping device 1207 in operative connection with the at least one clamping device 1207, in particular to exert a resultant adjustment, preferably effected by the resultant force. The connection point P is preferably arranged eccentrically to the axis of rotation S, preferably spaced apart from it with respect to the vertical direction V, in particular by a distance greater than zero. The connection point P is preferably arranged within the circumference of the at least one clamping device 1207.

[0133] Preferably, the at least one adjusting system 1219 is operatively connected to the at least one clamping device 1207 at only one connection point P. At the connection point P, all forces generated by the adjusting system 1219 preferably act as a single resultant force. The resultant force of the at least one adjusting system 1219 preferably counteracts a force exerted by the at least one rotating motion element 1204.

[0134] In a particularly preferred embodiment, the adjustment dependent on the applied stress is configured to act serially with the pulsed adjustment. "Serial" preferably describes an effect of the adjustments acting in series with one another. The stress-dependent adjustment and the pulsed adjustment preferably superimpose on each other and act as a resultant adjustment movement on the at least one clamping device 1207. In particular, the at least one actuating system 1219 is configured to exert the adjustments on the clamping device 1207 via a common operative connection, especially the connection point P.

[0135] A force flow from the at least one connecting device 1220 to the connection point P preferably runs via the at least one actuating device 1217. Preferably, the at least one actuating device 1217 forms a link between the at least one connecting device 1220 and the connection point P. Advantageously, this results in a force acting on the at least one connecting device 1220 being superimposed by a force acting on the at least one actuating device 1217, and a common resultant force acting on the at least one clamping device 1207, particularly at the connection point P. In a preferred embodiment, the at least one actuating device 1217 is arranged on a bracket 1233 of the machine tool 01. Preferably, the at least one actuating device 1217 is linearly movable and attached to the bracket 1233, for example, via at least one guide, in particular a guide rail.The at least one actuating means 1217, in particular its cylinder, preferably has a first position with a first distance to the connection point P and a second position with a second distance to the connection point P. For example, the second distance is less than the first distance. Preferably, the at least one actuating means 1217 is operatively connected to the at least one connecting device 1220, preferably its eccentric 1227, preferably with one side opposite the side to the piston exit 1218. The at least one connecting device 1220 is preferably designed such that it adjusts the at least one actuating means 1217 relative to the holder 1233, in particular linearly, and especially preferably between the first and second positions. Preferably, the cylinder and the piston 1218 of the actuating means 1217 are adjusted together.

[0136] In a first embodiment, the at least one actuating means 1217 is preferably configured to effect the clocked adjustment of the at least one clamping means 1207 and the adjustment dependent on the applied tension. Preferably, there is an electronic coupling to the drive system 1000. For example, no mechanical coupling to the drive system 1000 is provided, or it is at least temporarily interrupted. Advantageously, additional mechanical components are eliminated, and the design is simplified. However, due to the high dynamics and the particularly short response times, this embodiment complicates the design of the at least one actuating means 1217, and its stress increases, which, for example, reduces its service life.

[0137] In a preferred alternative embodiment, the positioning system 1219 comprises at least one positioning means 1217 and a mechanical coupling to the drive system 1000, preferably by means of at least one connecting device 1220. In this embodiment, the at least one positioning means 1207 is preferably configured to rotate the at least one clamping means 1207 about the axis of rotation S, particularly independently of the current machine cycle of the machine tool 01, depending on the current tension of the rotating motion element 1204. The tension-dependent angle of rotation γ is preferably less than or at most equal to the maximum angle of rotation β.The mechanical coupling, in particular the at least one connecting device 1220, is preferably designed to rotate the at least one clamping device 1207 in a clocked manner, i.e., synchronized with the current machine cycle of the machine tool 01, in and against the chain transport direction K about the axis of rotation S. The clock rotation angle δ is preferably smaller than or at most equal to the maximum rotation angle β. Advantageously, this alternative design relieves the at least one actuating device 1217, allowing for a simpler and smaller dimension. Advantageously, the necessary control is simplified, particularly preferably by a mechanical connection to the clocking drive 1001 of the machine tool 01, especially the main drive 1001. Advantageously, the machine cycle-dependent correction is carried out without delays due to reaction times of the control device 1101.

[0138] In one method, the tension, in particular the mechanical tension, of the at least one rotating motion element 1204 of the at least one transport system 1200 of the processing machine 01 is adjusted. The at least one rotating motion element 1204 is clamped by the at least one clamping device 1206 with the at least one clamping means 1207. The at least one clamping device 1206 advantageously compensates for fluctuations in the tension of the at least one rotating motion element 1204, in particular due to the cyclic and / or periodic motion and / or due to deflections of the rotating motion element 1204 during substrate processing. Advantageously, the running of the at least one rotating motion element 1204 is smoothed and vibrations are minimized.Advantageously, changes in the tension of the at least one rotating moving element 1204 due to aging and / or wear are counteracted.

[0139] The at least one moving element 1204 preferably makes first contact with the at least one clamping element 1207 at the first contact point 1211 and makes final contact with it at the second contact point 1212 with respect to the chain transport direction K. Preferably, the at least one moving element 1204 is deflected by the at least one clamping element 1207 and subsequently moves in a different spatial direction. Preferably, the at least one moving element 1204 is in permanent contact with the surface of the at least one clamping element 1207 between the first contact point 1211 and the second contact point 1212.

[0140] The at least one clamping device 1207 is preferably rotated about the axis of rotation S, particularly for adjusting the tension of the moving element 1204, with the maximum rotation angle β being less than 360°. The rotation angle of the actual adjustment is preferably less than or at most equal to the maximum rotation angle β. During an adjustment movement, the at least one clamping device 1207 is preferably rotated in the chain transport direction K and / or during a further adjustment movement, rotated against the chain transport direction K. The distance R1; R2 of the first and second contact points 1211; 1212 to the axis of rotation S preferably remains constant, particularly despite rotation.Particularly preferred, the distance R1 of the area point B11; B11'; B12; B12'; B10; B14 of the first contact area 1208 to the axis of rotation S remains the same, and the distance R2 of the area point B21; B21'; B22; B22'; B20; B24 of the second contact area 1209 to the axis of rotation S remains the same.

[0141] In an initial state, for example, area point B11 corresponds to the first contact point 1211 and area point B21 to the second contact point 1212. These area points B11 and B21 are preferably arranged rotated about the axis of rotation S by an internal angle α relative to each other.

[0142] By adjusting the at least one clamping device 1207 in the chain transport direction K, a contact point B12; B12'; B22; B22' located upstream of the chain transport direction K is preferably set to correspond to the contact point 1211; 1212. Preferably, this increases the contact length I12; I12' of the first contact area 1208 compared to the previously existing contact length I11 and decreases the contact length I22; I22' of the second contact area 1209 compared to the previously existing contact length I21.

[0143] By adjusting the at least one clamping device 1207 against the chain transport direction K, a contact point B11'; B12' downstream of the chain transport direction K is preferably set corresponding to the contact point 1211; 1212. Preferably, this reduces the contact length 111' of the first contact area 1208 compared to the previously existing contact length I11 and increases the contact length I21' of the second contact area 1209 compared to the previously existing contact length I21.

[0144] In a preferred embodiment, the first distance R1 of the first contact point 1211 to the axis of rotation S is smaller than the second distance R2 of the second contact point 1212 to the axis of rotation S. For example, the at least one clamping device 1207 is rotated in the chain transport direction K, preferably to reduce the tension relative to a tension state of the moving element 1207 without adjustment, i.e., preferably to compensate for an increase in tension of the moving element 1204. For example, the at least one clamping device 1207 is rotated opposite the chain transport direction K, preferably to increase the tension relative to a tension state of the moving element 1207 without adjustment, i.e., preferably to compensate for a decrease in tension of the moving element 1204.In a particularly preferred embodiment, the at least one clamping device 1207 is rotated in the chain transport direction K during a machine cycle associated with the dwell phase, preferably at the beginning of the dwell phase. For example, the at least one clamping device 1207 is rotated against the chain transport direction K during a machine cycle associated with the movement phase, preferably at the beginning of the movement phase, and / or to compensate for an elongation of the movement means 1204, for example due to aging or wear.

[0145] The at least one motion element 1204 is preferably moved forward in the operation of the processing machine 01 along the chain transport direction K, i.e., preferably with a cyclic and / or periodic motion profile. It is preferably guided by the guide elements 1229; 1231; 1232 of the at least one guide device 1203.

[0146] In a particularly preferred embodiment, the at least one clamping device 1207 is adjusted in a clocked manner, especially during operation of the machine tool 01, and is rotated around the axis of rotation S, wherein its actual positioning, i.e. its phase position, is set or is set depending on the existing tension.

[0147] The at least one clamping device 1207 is preferably rotated about the axis of rotation S in and against the chain transport direction K, preferably with the cycle rotation angle δ, in sync with a machine cycle. The clamping device 1207 is preferably rotated such that the resulting tension of the at least one moving element 1204 lies within a tolerance range, independent of the current machine cycle, and particularly preferably fluctuates within the tolerance range around the target value. Referring to the example with the range points B11 and B21 as the initial state, the clamping device 1207 is preferably rotated in a subsequent machine cycle, for example, a first machine cycle of the dwell phase, by the cycle rotation angle δ, for example, against the chain transport direction K, whereby the range points B12 and B22 preferably correspond to the contact points 1211 and 1212.In a subsequent machine cycle, for example, the first machine cycle of the movement phase, the at least one clamping device 1207 is rotated by the cycle rotation angle δ in the opposite direction, i.e., now in the chain transport direction K, whereby the area points B11 and B21 preferably again correspond to the contact points 1211; 1212. For example, the at least one clamping device 1207 remains in the respective position for at least one machine cycle, preferably until the next change between the dwell phase and the movement phase occurs. The contact length I11; I11'; I12; I21' of the first contact area 1208 and the contact length I21; I21'; I22; I22' of the second contact area 1209 preferably change from the first machine cycle to a second machine cycle. Particularly preferably, the contact length I22; I22' of the second contact area 1209 during the dwell phase is smaller than the contact length I12; I12' of the first contact area 1208.The contact length I21; I21' of the second contact area 1209 is particularly preferred to be greater than the contact length I11; 111' of the first contact area 1208 during the movement phase.

[0148] Additionally or alternatively, the at least one clamping device 1207 is rotated about the axis of rotation S, preferably with the tension-dependent angle of rotation γ, either in or against the chain transport direction K, preferably to increase the tension in the chain transport direction K, preferably independently of any existing machine cycle of the processing machine 01, preferably independently of any existing tension of the rotating motion element 1204, and in particular with the tension-dependent angle of rotation γ. For example, the at least one clamping device 1207 is rotated so that a reduction in tension compared to a previous tension state is compensated for. Preferably, the position thus set remains in place until a change in the existing tension of the motion element 1204 is preferably registered indirectly or directly, preferably by at least one sensor. Preferably, the tension-dependent adjustment is carried out depending on the measurement result of the at least one sensor.Referring to the example, with contact points B11 and B21 as the initial state, the at least one clamping device 1207 is preferably rotated by the stress-dependent angle of rotation γ, whereby contact points B11' and B21' preferably correspond to contact points 1211 and 1212 in this machine cycle. Due to the clocked adjustment, contact points B12' and B22' then correspond to contact points 1211 and 1212 in a subsequent machine cycle with clocked adjustment. The contact length I11, I11', I12, I21' of the first contact area 1208 and the contact length I21, I21', I22, I22' of the second contact area 1209 preferably change from the first state to the second state. The stress-dependent adjustment preferably takes the form of a rotation by the angle of rotation γ in the chain transport direction K.

[0149] The at least one clamping device 1207 is preferably adjusted in its positioning by the at least one positioning system 1219.

[0150] In particular, the at least one clamping device 1207 is adjusted by the at least one positioning system 1219 after a machine stop and / or during a job change and / or before the start of a machining operation, so that the tension of the at least one rotating motion element 1204 corresponds to a setpoint. Specifically, the at least one clamping device 1207 is rotated about the axis of rotation S by the at least one positioning device 1217. The at least one positioning device 1217 is preferably controlled by the at least one control unit 1101 such that the tension of the rotating motion element 1204 corresponds to a setpoint. For example, the rotation assigns the area points B11 and B21 to the contact points 1211 and 1212.

[0151] In a particularly preferred embodiment, the at least one positioning system 1219 causes the adjustment of the at least one clamping device 1207 to be timed with the machine cycle. Preferably, the timed adjustment is effected by the mechanical or electronic coupling to the drive system 1000 of the machine tool 01. Particularly preferably, the at least one drive 1001 of the drive system 1000 adjusts the at least one clamping device 1207 via the at least one connecting device 1220 in time with the machine cycle, especially in and against the chain transport direction K. The timed adjustment is particularly preferably position-based and / or displacement-based.

[0152] Preferably, during machining, the at least one clamping device is adjusted depending on the existing tension of the at least one rotating motion element 1204. The at least one positioning system 1219 preferably causes the at least one clamping device 1207 to be adjusted depending on the existing tension of the at least one rotating motion element 1204. The at least one control device 1101 preferably controls the adjustment of the at least one clamping device 1207, which occurs depending on the existing tension of the at least one rotating motion element 1204, based on a force and / or on a quantity proportional to the force, in particular pressure. Preferably, additionally or alternatively, position-based control of the at least one positioning device 1217 is carried out, wherein the position and / or stroke of the piston 1218 is particularly preferably monitored by sensors.The at least one sensor preferably detects an actual value of the at least one controlled variable. Preferably, depending on a comparison of the actual value with a setpoint of at least one evaluation unit, the at least one actuator 1217 is then preferably controlled by the at least one control device 1101 and, if necessary, its state is changed. The at least one actuator 1217 is preferably controlled at at least one time based on a force and / or on a quantity proportional to the force, preferably pressure-based, and / or at at least one time based on position, preferably based on the position of a component, in particular the piston 1218, of the at least one actuator 1217.Particularly preferably, the at least one actuating means 1217 causes the adjustment of the at least one clamping means 1207 by regulating the quantity and / or a prevailing pressure of a pressure medium within the actuating means 1217 designed as an actuating cylinder 1217, preferably as a hydraulic cylinder 1217.

[0153] In a particularly preferred embodiment, the controlled variable of the at least one actuator 1217 fluctuates within the tolerance range around the setpoint. In particular, the controlled variable of the at least one actuator 1217 is regulated to fluctuate within the tolerance range around the setpoint. Most preferably, the at least one actuator 1217 is controlled by the at least one control device 1101 such that the controlled variable increases to a maximum value within the tolerance range and then decreases to a minimum value within the tolerance range. This control loop, with the controlled variable increasing and decreasing, preferably within the tolerance range, is preferably repeated continuously.For example, the controlled variable increases from a value within the tolerance range lower than the setpoint, such as the minimum value of the tolerance range, to a value within the tolerance range greater than the setpoint, such as the maximum value of the tolerance range. Subsequently, the controlled variable is reduced again, for example, to the setpoint or a value lower than the setpoint. This fluctuation of the controlled variable, generated by the control system, particularly advantageously compensates for the vibrations of the rotating motion element 1204. The piston 1218 is preferably adjusted slowly relative to the alternating phases of the machine cycle and exhibits only small positional differences.The particularly advantageous design of the actuating device 1217 as a hydraulic cylinder 1217 enables a particularly precise and rapid adjustment, which advantageously does not introduce any new vibrations into the system. For example, individual deviations of the controlled variable, such as changes briefly generated by the machining process, are permissible outside the tolerance range, as long as the subsequent control operation restores a value within the tolerance range.

[0154] Particularly preferably, the at least one actuating means 1217, particularly preferably the at least one actuating cylinder 1217, and even more preferably the at least one hydraulic cylinder 1217, of the at least one actuating system 1219 effects at least the adjustment dependent on the applied tension. In a preferred embodiment, the mechanical coupling to the drive system 1000, in particular by means of the at least one connecting device 1220, effects the pulsed adjustment of the at least one clamping means 1207. In an alternative preferred embodiment, the at least one actuating means 1217 effects, in addition to the adjustment dependent on the applied tension, the pulsed adjustment of the at least one clamping means 1207. Or the pulsed adjustment is omitted.

[0155] In a particularly preferred embodiment, the at least one adjusting system 1219 effects the pulsed adjustment and, additionally, the adjustment depending on the applied tension. The tension-dependent adjustment preferably acts in series with the pulsed adjustment. Particularly preferably, the at least one adjusting system 1219 exerts the resulting adjustment on the at least one clamping device 1207 at the connection point P, which is preferably arranged eccentrically to the axis of rotation S.

[0156] The use of the clocked adjustment of the at least one clamping device 1207 advantageously counteracts an increase in friction during the dwell phase.

[0157] In a further alternative embodiment, the at least one clamping device 1207 is not adjusted in a timed manner. Preferably, there is no mechanical coupling to the drive system 1000, or this coupling is at least temporarily decoupled. In this further alternative embodiment, the clamping of the at least one rotating motion element 1204 is preferably adjusted by the at least one actuating device 1217 of the at least one actuating system 1219. In particular, the at least one clamping device 1207 is adjusted by the at least one actuating system 1219 after a machine stop and / or during a job change and / or before the start of a machining operation, in particular rotated about the axis of rotation S, so that the clamping of the at least one rotating motion element 1204 corresponds to a setpoint.For example, by rotating the at least one clamping device 1207 by the rotation angle γ, the area points B11 and B21 are adjusted to correspond to the contact points 1211 and 1212. Thus, a tension-dependent adjustment of the at least one clamping device 1207 preferably takes place at least once.

[0158] In the first variant, in the further alternative embodiment, the adjustment of the at least one clamping device 1207 preferably takes place during machining operations in a tension-dependent manner. Particularly preferably, the adjustment of the at least one clamping device 1207, which occurs depending on the existing tension of the at least one rotating motion element 1204, is controlled based on the force and / or on a quantity proportional to the force, in particular the pressure. The controlled variable of the at least one of its adjusting elements 1207 preferably fluctuates within the tolerance range around the setpoint. Advantageously, this minimizes the vibrations of the system.

[0159] In a second variant, the alternative embodiment involves position-based control of the at least one actuating device 1217 during machining. Preferably, the position and / or stroke of the piston 1218 is monitored by sensors. In particular, the at least one control unit 1101 controls the at least one actuating device 1217 such that the position of the piston 1218 remains constant. Thus, the at least one clamping device 1207 preferably maintains a constant position during machining. Preferably, the setpoint of the controlled variable is checked and, if necessary, changed at the next machine stop and / or next machining operation. For example, by manual input and / or automatically after a predetermined time interval, such as once an hour, the setpoint of the controlled variable is changed during ongoing machining to react to a decrease in the tension of the moving device 1204.

[0160] In particular, the method for adjusting the tension of the at least one moving element 1204, preferably in that the at least one clamping element has a clocked adjustment and additionally a tension-dependent adjustment, especially preferably the serial action of the adjusting system 1219, is also applicable to clamping devices with a structural difference from the embodiment described above and / or is applied in these, especially as long as no contradiction arises. In an alternative embodiment, for example, the at least one clamping device 1206 has at least one pivot lever and / or at least one linear guide for adjusting the at least one clamping element 1207. Additionally or alternatively, the at least one bearing of the at least one clamping element 1207 is adjustable in its position by at least one eccentric.Preferably, in an alternative embodiment of the clamping device 1206, the at least one clamping element 1207 is pivoted around the pivot point of the pivot lever and / or adjusted in or against the transport direction T, preferably linearly or by means of the eccentric, as an alternative to rotation in or against the chain transport direction K for adjusting the tension. Preferably, in an alternative embodiment of the clamping device 1206, the bearing of the at least one clamping element 1207 is adjusted. In this embodiment, the at least one clamping element is preferably designed as a centrally mounted circular arc, as an alternative to the embodiment described above. In this embodiment as well, an adjustment dependent on the applied tension preferably acts serially to the pulsed adjustment, preferably at the at least one connection point P.

[0161] As an alternative to the configuration of the chain transport system 1200 for transporting substrate 02 through the at least one processing unit 300; 400, the chain transport system 1200, comprising the at least one clamping device 1206, is configured, for example, as a transport system for substrate to a final processing unit of a processing machine, which takes over a substrate from another transport means of an upstream processing unit or a drying device and transports it to a delivery position in a delivery tray. This is used, for example, in sheet-fed rotary printing presses.

[0162] As an alternative to the design of the transport system 1200 as a chain transport system 1200 comprising at least one chain 1204, the at least one circulating moving element is designed, for example, as a belt or cloth. Preferably, the transport system also has the at least one tensioning device 1206 in this example.
