Description

  The present invention relates to a transport apparatus according to the superordinate concept of claim 1 or a method for transporting a substrate sheet according to claim 12, particularly a substrate panel.

  In European Patent Publication No. 0412720, an apparatus and method for printing on metal plates is known. In this printing apparatus and method, the metal plate to be printed can be supplied to the nip position of the printing unit by the feeding means. A gauge lever with a stopper surface is provided on the impression cylinder to guide the metal plate through the nip position in a registering manner relative to the printing part cylinder. When the metal plate arrives, the stopper surface cooperates with a portion traveling on the front side to limit the distance. The gauge lever can be rotated around an axis parallel to the trunk axis in a region far from the stopper. In order to counter the disadvantageous effects resulting from the superimposition of the rotation of the cylinder and the rotational movement of the gauge lever in the opposite direction depending on the phase, the rotation axis is arranged outside the circumferential contour of the cylinder Yes. The rotatable gauge lever is provided with stopper means in the region of its free end. The stopper means is adjustably attached to the gauge lever with respect to its position, so that the effective length of the lever between the pivot axis and the stopper surface can be adjusted. The gauge lever is pivotally mounted by a lever of the drive mechanism for movement between the rotation axis and the stopper surface, and the lever of the drive mechanism is driven in a relative manner to the cylinder rotation by the cam means. ing.

U.S. Pat. No. 2,699,940 relates to a printing machine for printing a hard sheet-like substrate. In this printing press, the impression cylinder includes a plurality of registration elements. The registration element is configured as a gripper at an end projecting from the cylinder circumference, which cooperates with the substrate. In order for the gripper-shaped end portion to perform a tangential motion component in addition to the up-and-down motion, the gripper-shaped end portion is connected to two circumferentially spaced two couplers via two rotatable couplers. It is supported movably. The coupler is supported at its other end by a shaft, each having a fixed axis, and one of the two couplers is forced relative to the cylinder rotation via a cam transmission. It is rotated to be driven. In an alternative mode, a lever such as a gripper is rotatably supported on the first shaft, and the first shaft itself is connected to the second shaft having a cylinder fixing axis via the lever. It is pivotable about the center. The rotation of the first axis around the second axis and the rotation of the gripper lever around the first axis are controlled via one cam transmission device.

EP 1678066 relates to a gripper cylinder in a folding device of a rotary printing press having a gripper control device. In this gripper cylinder, a gripper arm that supports the gripper tip is pivotally attached to two levers spaced in the radial direction, and each lever is driven via a cam transmission. In order to shorten the movement at the time of holding between the entering position and the leaving position, the axis of the gripper arm itself is moved in the radial direction by the cooperation of the lever. In order to hold the front edge of the printed product, the gripper is first retracted under the trailing edge of the preceding product and the end to be held in the direction opposite to the rotational direction. Is turned on .
Also European Patent Application Publication No. 0931748, relates cylinder in the folding of a printing press for processing a web apparatus. Through the cooperation of the control cam and the control roller, the gripper is first withdrawn, and then the movement opposite to the rotational movement of the cylinder configured as the folding blade cylinder is performed.

  In DE-A 1 957 507, a drive device for a cylinder gripper element in a folding device of a printing press is also known. In this drive device, the gripper element is supported on a rotatable support body through a slide guide or a slide link guide so as to be movable in the radial direction. Through the guide, an approaching movement and a leaving movement of the support that supports the gripper element are performed. The approaching movement, the leaving movement and the turning movement are each operated via a control cam.

  In EP 1 472 164, a conveying system for a sheet metal printing machine or sheet metal coating machine with a belt system is known, in which the panels are precisely aligned without a rear feeding system. Should be supplied. Due to the speed difference between the suction belt and the gauge (front), the leading edge of the panel is continuously pressed against the gauge until the gripper system is closed, in which case the sheet metal panel is suctioned by a vacuum that can be activated periodically. By being attracted to the belt, an accurate supply is achieved.

  In the pamphlet about the MAILENDER 222 type thin metal plate printing machine of KBA-MetalPrint GmbH in 2011, a conveyance path to a printing unit having a conveyance section inclined with respect to an upstream conveyance direction is known.

  In U.S. Pat. No. 5,253,583, a sheet-like material printing machine is known, in which a pressure lever is provided with a gauge lever provided with a stopper means for the edge of the printed sheet running on the front side. Is provided. The stopper means can be positioned by the motor along the moving direction of the sheet on the gauge lever in order to adjust the correct relative position of the sheet. The adjustment of the stopper means can also be performed during the printing operation.

  U.S. Pat. No. 2,699,941 relates to a printing machine for printing on a hard sheet-like substrate. In this printing press, the impression cylinder is provided with a register element. The register element is configured in a gripper shape at an end portion that cooperates with the substrate and protrudes from the circumference of the body. Since the gripper-shaped end part performs not only pure up-and-down movement but also tangential movement components, the end part is supported rotatably at two places of the connecting part spaced in the circumferential direction. In this case, one of the connecting portions is forcibly driven and rotated relative to the cylinder rotation via the crank transmission.

  The problem underlying the present invention is to provide a transport device for transporting a substrate sheet, in particular a substrate panel.

  This problem is solved according to the invention by the features of claims 1 or 12.

  According to the advantages obtained by the present invention, a slight acceleration value is obtained, in particular when a substrate sheet, in particular a substrate panel, comes into contact with the gauge, which makes it possible to run particularly quietly.

  In the case of a higher feed rate relative to the peripheral speed of the cylinder in the transfer section, the improved stopper device can change the movement of the gauge extending along the transfer device on its movement path, and as a result The movement of the gauge substantially coincides with the feeding speed of the conveying section in the first contact area located before the print gap, and substantially coincides with the peripheral speed of the cylinder supporting the stopper device in the area of the nip position. This allows controlled continuous braking, thus avoiding the rebound action. Thereby, at the first contact or zero point (for example when the gripper is closed), an optionally spring-supported rear pressing member, or an optionally spring-supported drive system in the case of a transport path in front of the nip position, For example, it becomes possible to reduce the elastic deformation force in the conveying means of the supply frame.

  By avoiding sudden braking, in addition to less rigid panels, especially thicker metal panels (eg> 0.1 mm or even greater than 0.3 mm) as substrate sheets, especially substrate panels A metal panel with a small thickness, for example a sheet metal panel with a thickness of ≦ 0.1 mm, or a panel made of another sensitive material (for example a plastic panel, wood panel or cardboard panel) is also located in the supply part without damage In combination, it can be supplied to a processing unit, for example, a printing section or a coating section.

  In a particularly preferred manner, the feeding device allows the initial contact between the gauge and the substrate to be early, i.e. largely before the zero and / or nip position, e.g. the impression cylinder is still at least 20 °, preferably This can be done at a point in time 30 ° before the zero position. In this case, in the printing section, the zero position should be understood as, for example, a position where the front edge of the panel contacting the gauge enters a theoretical nip line, that is, a plane connecting the rotation axis of the cylinder forming the printing position. is there. Early "clamping" of the approaching panel between the gauge and the propulsive force exerted through the conveying section, for example the spring-supported rear pressing member and / or the friction force exerted by the magnet or negative pressure The seat travel or panel travel settles down.

  The rebound action, i.e. shocking contact, between the gauge and the rear pressing member and possibly the side pressing member is thus greatly reduced, which is relative to registration accuracy and production reliability. Works in an advantageous manner. In some cases, normally necessary front control of the rear-side pressing member provided in the transporting means placed in front, for example, the plurality of transporting means of the supply frame, can be omitted. Instead, it is only necessary to set up a simple return control of the optionally provided rear pressing member, this return control being configured, for example, after closing the gripper, ie as an additional gripper and / or simultaneously as a gripper. After fixing of the sheet or panel by the gauge lever, it acts on the space between the rear pressing member and the rear edge of the panel that may be present.

  The stopper device is interlocked but is configured with a “hard” stopper defined for every point in time with respect to vertical registration, ie a “hard” stopper. In a preferred refinement, the stop device cooperates with a transport device comprising means for producing a restriction of the force acting on the substrate sheet for feeding, at least in a limited movement phase. Despite the provision of a “hard” stopper for the purpose of registration for the edge 13 running on the front side, the “soft” feed within at least a certain range allows only the rebound action at the side of the conveying device. In other words, the risk of deformation of the substrate sheet is reduced.

  In one refinement, the bending guide path, in combination with the means for assisting deflection, achieves a reliable and lateral reinforcement of the substrate sheet independent of the inherent weight of the substrate sheet. . On the basis of the lateral reinforcement, at the same time, a straight advance of the edge running on the front side and approaching the stopper device is guaranteed. The means for pressing the conveyed printing material sheet against the mounting surface in the area of the guide for bending acts so that the printing material sheet bends in a predetermined shape against the rigidity in the vertical direction.

  In a machine for processing a printed sheet 01, preferably a printed sheet 01 configured as a printed panel 01, in particular a printing machine and / or a coating machine, the printed sheet 01, preferably the printed panel 01, It is transported along the transport path via one or more transport devices 04; 06. On the conveyance path, the substrate sheet 01 is processed, that is, printed and / or coated on at least one surface thereof by one or more processing units 02; 03. In order to guarantee the correct processing with respect to the vertical register, at least one part of the transport path, especially in front of the transport section, that is, the object transported close via the transport device 04; 06 arranged upstream. A device 09 for aligning the printed material sheet 01, in particular the printed material panel 01 in a correct manner, a cylinder 07; 08 provided with a stopper device 09 for short.

  By the cooperation of the transport device 04; 06 that transports the substrate sheet 01 and the stopper device 09, the substrate sheet 01 is supplied to the stopper device 09 as it is, and is correctly aligned in the case of an inclined posture that occurs in some cases. Is done. For this purpose, the transport device 04; 06 arranged immediately before the cylinder 07; 08 is preferably operated at least temporarily at a higher feed or transport speed relative to the peripheral speed of the cylinder 07; 08. Or it is driven. For example, at least temporarily at a higher feed speed, the edge 13 running on the front side of the substrate sheet 01, that is, the front edge, is pressed against at least one stopper means 11 of the stopper device 09.

  The transport device 04; 06 includes at least one means 05 for transporting the printed sheet 01, for example, a circulating travel means 05, or a transport means 05 for transporting the printed material sheet 01 that circulates, for example, the transport apparatus 04; 06 comprises a belt system comprising one or more circulating running means 05, for example configured as a circulating running belt 05. On one or a plurality of circulating travel means, the printed material sheet 01 is arranged in the conveying direction on the rear side of the printed material sheet 01 arranged in a belt 05 or a tension device that is different from the belt 05 but also circulates. By a shape coupling with the stopper 15 acting on the traveling end, that is, the rear end, for example, the rear side pressing member 15 (the shape coupling means a coupling based on a mutual relationship between members such as fitting or meshing), Alternatively, the pressure drop unit 25 is configured as a means 25 for generating a negative pressure P−, for example, a means 25 for generating a negative pressure P−, for example, a means 25 for increasing the mounting force and consequently the friction, for example, by the self-weight or assisted by the means for increasing the friction. By means of force coupling (friction) with the belt system or by, for example, the magnetic force of a magnet 25, in particular an electromagnet. Preferably, the action of the means 25 can be varied and / or configured to be selectively actuable and inactive.

  In order to avoid deformation of the substrate sheet 01 at different speeds after the first contact, the transport device 04; 06 in cooperation with the cylinder 07; 08 with the stopper device 09 is preferably for feeding Means 53; 54; 67; 56; 81; 82; 83; 84; 98 for limiting the force acting on the substrate sheet 01 are provided. These means for limiting the feeding force applied to the substrate sheet 01 can be realized in various forms in principle depending on, for example, the characteristics of the conveying means (this is described below with reference to FIGS. 10 to 18). See also).

  As a typical example and representative example of possible implementations of the transport device 04; 06 in front of the cylinder 07; 08, the transport device 04; 06 comprises a belt system having a rear pressing member 15 in FIG. In FIG. 2, it is schematically shown as at least one belt 05 that circulates and has means 25 for increasing friction or mounting force.

  As already described, the machine for processing the substrate sheet 01 or substrate panel 01 comprises at least one processing unit 02; 03, for example at least one printing section 02 (for example FIG. 8) and / or at least one coating. An engineering unit 03 (for example, FIG. 9) is provided. With the processing units 02; 03, the substrate sheet 01 that is particularly configured as the substrate panel 01 can be printed or coated on at least one side. On the same processing path of the machine, at least one printing unit 02 and at least one coating unit 03 may be provided in succession in the transport direction.

  In principle, one or more of the cylinders 07; 08 together with the front conveying devices 04; 06 may be provided in the conveying path of the machine. Thus, such a cylinder 07; 08 comprising a stopper device 09, as an adjusting part, in the form of a supply cylinder 08 or a supply drum 08, on the exposed conveying section and / or in the inlet area of the processing unit, and The functional unit of the processing unit 02 including the stopper device 09 may be configured, for example, as a cylinder 07 including the stopper device 09 as a contact device, particularly as the printing unit cylinder 07.

The substrate sheet 01 to be transported and processed by the machine may in principle be configured as a sheet, for example as a thicker sheet, for example up to a material thickness of at least 1 mm or as a cardboard However, in a preferred embodiment, it is configured as a hard substrate sheet 01 or from a hard material, for example, in the form of a panel 01, for example, a substrate panel 01. The to-be-printed panel 01 may be preferably configured as a metal panel 01, particularly a metal thin panel 01. In the preferred meaning of the present specification, the substrate sheet 01 or the substrate panel 01 is different from, for example, a thin sheet. For example, with respect to a longitudinally extending length extending in the conveyance direction, characterized in that it also has a higher basis weight of very high flexural stiffness and / or for example at least 1 kg / m ^2, in particular ^{1kg / m 2 ~3kg / m 2} . The substrate sheet 01 or the substrate panel 01 is, for example, not slightly wound around a rotating conveying cylinder or the curved surface of a roller, but rather slightly bent and / or slightly via such a roller and cylinder. Further, it is characterized in that it is wound almost in a negligible range of, for example, less than 20 °, and is transported almost straight. Therefore, in that sense, in addition to a preferred embodiment as a metal panel 01, for example, a metal thin plate panel 01 made of a tin plate or an aluminum plate, in particular, the panel is constructed in a bending rigid manner in the above sense, for example. In this case, a panel 01 made of a sensitive material is also conceivable, for example a panel made of plastic material, wood, composite material or cardboard. In the following, where it is not clearly distinguished, the universally expressed description “printed sheet” is one of the special embodiments as one printed substrate panel 01 of the previously described embodiment, which is preferably made of metal. It is also understood.

  The cylinder 07; 08 cooperates with the panel-like printed sheet 01 in particular to guide and align it, in which case the printed sheet 01 is substantially tangential on the cylinder circumference of the cylinder 07; 08. Travels in the direction and does not touch particularly large circumferential regions. In this case, the stopper device 09 is registered with respect to the accurate conveyance direction of the edge portion 13 that runs on the front side of the substrate panel 01 that has been transported close to the transport device 04; 06 placed on the transport path. Used for street supply. The stopper device 09 comprises at least one stopper means 11 having a stopper surface 12, preferably a plurality, for example two, of the stopper means 11 spaced apart from one another in the axial direction. The stopper means 11 can be moved periodically and / or relative to the barrel rotation by the first drive mechanism, so that the end supporting the stopper surface 12 has a predetermined first movement. Able to move along a trajectory between a first position and a second position radially spaced from the first position with at least one radial motion component with respect to the cylinder 07; 08 . In the second position, the free end that supports the stopper surface 12 preferably protrudes from the circumference of the cylinder 07; 08, for example, more than the first position, which is mostly held inside the circumference. To do.

  The stopper means 11, which can be moved periodically and / or relative to the cylinder rotation, the so-called gauge lever 11, as a result, has at least one radial movement component between the inner position and the outer position. If the movement of the free end provided with the stopper surface 12 is or can be realized in principle, it can be configured in any form. , And supported by the cylinder 07; 08, and may be driven by the first drive mechanism. For example, the stopper means 11 called, for example, the gauge lever 11 is supported by a predetermined guide, and the guide means may be reciprocally movable along a straight line or along a curved track. In this case, at least one, in particular mainly radial trajectory component or motion component, may be set.

  Preferably, the stopper means 11 is configured in the form of a pivotable lever as the gauge lever 11, in this case from a free drive side between the first position and the second position. The relative movement of the far end is performed by the rotation of the gauge lever 11 about the axis A which is parallel to the barrel axis, preferably located inside the circumference, in particular the axis A of the barrel fixing. . For this purpose, one or more (both) gauge levers 11 are pivotable on the shaft 14, but not relative to the shaft 14 which is supported in a fixed manner, ie fixed in position relative to the barrel. (That is, rotate together). As typical and representative examples of possible aspects of cylinder 07; 08 (see 24 below), cylinder 07 is shown in the form of a printing section cylinder 07 in FIG.

  The driving of the gauge lever 11 or the shaft 14 associated with the cylinder rotation can in principle be carried out mechanically via independent drive means independently of the cylinder rotation, in which case the association is e.g. electromagnetic It may be realized in the form of a formula or a circuit technology formula.

  Preferably, however, the drive of the gauge lever 11 or the shaft 14 associated with the cylinder rotation is effected via the cam transmission 16. The cam transmission device 16 forms a first drive mechanism with, for example, a shaft 14 that supports one or more gauge levers 11 and possibly another intermediate member. In this case, for example, the roller 18 disposed at the free end of the lever 17 that is coupled to the shaft 14 so as not to rotate relative to the shaft 14 rolls on the cam disk 19 that is disposed at a fixed spatial position. The molded shape of the cam disk 19 sets the vertical movement of the gauge lever 11 via the roller 18, the lever 17 and the shaft 14 when the cylinder 07; 08 is rotated.

The panel 01 to be guided close to the cylinder 07; 08 is moved immediately before the edge 13 running on the front side of the panel 01 travels at least on the cylinder 07; 08 via the transport device 04; 06 provided in front. For example, at least a predetermined section length of at least 5 cm, preferably at least 10 cm, so as to travel along a substantially straight moving track B _T before the first contact. The trajectory B _T preferably matches a tangent, or alternatively a secant that is parallel to the tangent and shifted to a few millimeters, for example 10 mm.

On the one hand, along the movement of one trunk circumference point of the barrel fixed to the rotational movement projected at a constant peripheral speed projected on the movement trajectory B _T , on the other hand, along the first movement trajectory (for example, rotational movement), Based on the sinusoidal speed course of the movement of the free end of the stopper means 11 which is moved relatively in the cylinder 07; 08, superimposed on the constant barrel rotation, the stop surface together with the free end and the free end If there is no other configuration means, the movement of the different shape projected on the moving trajectory B _T is performed. The adverse effect on the transport properties of the panel 01 resulting therefrom is that under this condition, the contact between the stopper surface 12 and the edge 13 running on the front side is as short as possible, preferably in the tangential direction. It can be suppressed only by being reduced to a range of contact points with the extended moving track B _T.

However, this is the purpose to be pursued there, that is to say that the panel 01 to be supplied is as early as possible, until the panel 01 travels on the cylinder 07; Countering guidance over a distance section of at least 5 cm or a barrel movement of at least 20 °. In this case, this indicator, the stop surface 12, the portion which acts at each time point is preferably cylinder 07; at a substantially constant speed that matches the circumferential speed of 08, is moved along the movement trajectory B _T Should be or have been moved.

  In order to make this possible or at least as close as possible to its purpose, according to the invention, the stopper means 11, in particular configured as a gauge lever 11, comprises, for example, a stopper element 21 and a stopper element 21 from a plurality of parts. The stopper element 21 with the stopper surface 12 is not fixed but, in some cases, simply moves along the first movement trajectory. Arranged on the arm 22, for example the lever arm 22, in such a manner that it can be adjusted relative to a possible lever and can be moved relative to one another along a (second) movement trajectory, in particular in a translationally relative manner, 2) the drive mechanism 23 can be forcibly driven periodically with respect to the movement relative to the arm 22 and / or relative to the movement of the arm 22. It is.

  Therefore, the gauge lever 11 with the stopper element 21 is entirely, periodically and / or relative to the cylinder rotation, with at least one, in particular mainly radial component, by means of the first drive mechanism. In this case, the stopper element 21 with the stopper surface 12 is supported on the gauge lever 11 in such a way that it can move in a relative manner, in particular in the region of the free end. The second drive mechanism 23 is preferably forcibly driven or forcibly driven periodically and / or relative to the movement of the arm 22. The second movement, also along a predetermined second movement trajectory, has at least one movement component tangential with respect to the cylinder 07; 08, in particular with a predominantly tangential component, the first position and the cylinder 07; And a second position spaced from the first position in the circumferential direction of 08.

  In an existing relationship, a motion with a predominantly radial component is to be understood as a motion in which the radial stroke is greater than the tangential stroke that is sometimes performed simultaneously by that motion. Conversely, a motion that has a predominantly tangential component should be understood as a motion in which the tangential stroke is greater than the radial stroke that is sometimes performed simultaneously by the motion.

  Thus, the stopper surface 12 is not fixedly placed on the stopper means 11 which is moved in response to operation during the entire one-turn movement cycle of the cylinder 07; It is a component of the stopper element 21 which is arranged in the stopper means 11 as possible and is likewise forcedly or forcibly moved periodically.

The stopper element 21 is arranged on the gauge lever 11 so as to be capable of relative movement, for example, on its arm 22 and / or is driven or configured to be driven by a second second driving mechanism 23. According to this, the stopper element 21 comes into contact with the edge 13 of the substrate sheet 01 to be transported in close proximity, provided that the substrate sheet 01 is preferably not yet running on the cylinder 07; 08 (24). In one stage, the stopper element 21 in the gauge lever 11 is in a direction having at least one motion component in the rotational direction of the cylinder 07; 08 (24) and / or along the movement trajectory B _T of the substrate sheet 01. Can be exercised or can exercise.

  The structure of the stopper means 11 and the drive mechanism (23) of the arm 22 and the stopper element 21 are harmonized with each other, whereby the stopper element 21 in contact with the substrate sheet 01 is the cylinder 07; When viewed in the circumferential direction of 08 (24), it moves in the rotational direction or the moving direction of the substrate sheet 01.

  The stopper means 11 configured according to the present invention, which mainly performs the first radial movement in the above-described form, and the stopper element that causes the first stopper means 11 to generate a relative movement mainly in the tangential direction. 21 is also referred to as a pre-controllable or pre-control type stopper device 09 below.

  The periodic drive of the stopper element 21 can in principle also be correlated to the cylinder rotation, and in some cases directly or mechanically or electronically connected to or associated with the cylinder rotation. In the case of an electronic or circuit technology connection, a unique drive means may be provided for the movement of the stopper element 21.

  However, preferably, the stopper element 21 is directly connected to the rotational movement of the cylinder 07; 08 (24) via the second drive mechanism 23, for example the transmission device 23, or preferably indirectly to the stopper means 11, in particular. By being connected to the rotational movement of the cylinder 07; 08 (24) via the movement of the arm 22 (which is associated with the rotational movement), the unique drive means can be omitted.

  When directly connecting to the rotational movement of the cylinder 07; 08 (24), in addition to the first cam disk 19 having a fixed spatial position, another cam disk having a fixed spatial position (not shown) may be provided depending on the operation. Often, this further cam disc forms the second drive mechanism 23 in the form of a cam transmission comprising a roller and a lever coupled to the stopper element 21. However, in a preferred embodiment, the forced relative movement of the stopper element 21 is not caused by the cam disk fixed at a spatial position, but by the movement of the stopper means 11 (gauge lever 11) having the stopper element 21 or the arm 22 thereof. In combination with the fixed connecting part (for example, see below with respect to FIGS. 4 and 5 via the connecting part 28 or the cam transmission 32).

The relative movement of the stopper element 21 is different from the movement direction of the first movement, and the circumferential and / or tangential (extremely large) component of the cylinder 07; 08 (24). so long as it has, in principle, it can be carried out along various motion trajectories B _R. Thus, for example, a rotational movement in the direction opposite to the first movement around the rotation axis of the gauge lever can be set, and this rotational movement is, for example, the sinusoidal tangential velocity described above. Compete against your profile. Similarly, a translational movement along a given guide may be set up, which may be curved or not formed straight at least over the entire range of motion. In this case, such a motion trajectory B _R of the relative motion, may have been specifically adapted to the motion required by the superposition of the first movement.

In a preferred embodiment shown, the relative movement of the stop element 21 with respect to the arm 22 is carried out along a straight movement path B _R. Straight movement path B _R is be oriented to the arm 22, according to which, preferably, the stopper means 11, i.e. the arm 22 including a stop element 21, the position of the stop surface 12 passes through the zero position L ₀ when in, the movement path B _R is approximately (e.g. ± 5 °, in particular at the maximum error of up to ± 3 °) cylinder 07; extending tangentially to 08 (24).

The zero position L ₀ is an angular position with respect to the rotation axis of the cylinder 07; 08 (24), and the radius of the cylinder 07; 08 (24) and the transport direction T _{0 of the} panel 01 are the cylinder 07; 08 (24). It is interpreted as an angular position orthogonal to each other at a contact point with (or a contact line extending in the axial direction). If the panel 01 contacts the cylinder in a small angle range due to an elastic and / or compressible deformation of the cylinder surface and / or a slight deflection of the panel 01 rather than approximately on the contact line, this angle range is halved. The position to be taken should be interpreted as the zero position L ₀ . First cylinder 07 is, another cylinder 24, for example, with the printing unit cylinder 24, to form a nip position through the substrate sheet 01 or panel 01 to be transported, the zero position L ₀ is, for example, both of the body 07; coincides with a line connecting 24 rotation axes.

Principle regardless the specific configuration of the second motion trajectory B _R, however, preferably in connection with its straight configuration, the transmission 23 or the second drive to elicit relative movement of the stopper element 21 The mechanism 23 has a pivoting portion of the stopper element 21 obtained via a coupling part consisting of one or more members with respect to the barrel-fixed receiving part 26; 31, so that the movement of the stopper means 11 comprising the stopper element 21 is achieved. At times, the stopper element 21 is supported by a receiving part 26;

  In the first aspect, the connecting portion between the operating point of the stopper element 21 and the operating point acting on the pivotally fixed portion of the trunk has a fixed (effective) connecting portion length l.

  In a preferred first configuration of the first aspect, which is not very complicated mechanically, the connecting portion is formed by a coupler 28. On the one hand, the coupler 28 is rotated to a stopper element 21, for example a support element 35 arranged on the stopper element 21, for example via a pin 29 or a shaft 29, and on the other hand via a pin 31 or a shaft 31. It is pivotally mounted on the cylinder 07; 08 in such a way that it can be moved, in which case the axes of the joints that can be pivoted each preferably extend parallel to the cylinder axis. The rotation axis of the barrel fixing, that is, the pin 31 or the center of the shaft 31 extends at a distance from the trunk axis and at a distance from the turning axis of the gauge lever 11. In this case, the shaft 31 is configured as a receiving portion 31, and the stopper element 21 is supported on the receiving portion 31 via a coupler 28. The stopper element 21 pivotally mounted at a distance from the rotation axis of the gauge lever 11, for example, by the movement of the entire stopper means 11, in particular the movement of the gauge lever 11 or its arm 22, in particular the rotation, is provided by the connecting portion. The above relative movement is forced.

  In an alternative configuration of the first aspect, the connecting part or the pivoting part is realized by a cam transmission device 32 which, on the one hand, rotates, for example via a pin 33 or a shaft 33. The stopper element 21 is preferably provided with a roller 34, for example arranged on a support element 35 which is arranged in a fixed position on the stopper element 21, the roller 34 being arranged, for example, on a pin 31 or in other forms on the cylinder 07; 08 , In cooperation with a stopper element 26 which is fixed in particular as the receiving part 21. In this case, in this configuration, at least the circumferential section of the stopper element 26 that cooperates with the roller 34 during the movement cycle has an annular section-like profile. The axis of the rotatable roller 34 as well as the center of the annular contour each preferably extend parallel to the barrel axis. The center of the annular or annular segmented stop element 26 extends at a distance from the barrel axis and preferably at a distance from the pivot axis of the gauge lever 11. The effective connecting portion length l is set by the radius of the roller 34 and the annular (sectioned) stopper element 26. In order to obtain the action on both sides of the connecting part, a spring element 27, for example a compression spring 27, is further arranged corresponding to the connecting part, by means of which the roller 34 exerts a force in the direction of the stopper element 26. receive. For this purpose, the spring element 27 acts, for example, directly or indirectly on the arm 22 of the stopper means 11 and on the other hand on the stopper element 21 which supports the roller 34. Instead of the compression spring 27, a tension spring may be used in consideration of the force direction. Preferably, the spring element 27 biases the preload in the direction of the stopper element 26. In this case, the cylinder-fixed stopper element 26 forms a receiving part together with the spring element 27 as occasion demands, and the stopper element 21 is supported by the receiving part via a roller 34. A cam in which a stopper element 21 pivotally mounted at an interval with respect to the rotation axis of the gauge lever 11 is preloaded by the movement of the entire stopper means 11, in particular the gauge lever 11 or its arm 22, in particular rotation. The relative movement is forced by the connecting portion configured as the transmission device 32.

  In a second embodiment (not shown), for example suitable for the second configuration of the first embodiment, the stopper element 26 is in an angular range, i.e. in a relative curve segment or curve segment. It is not an annular segmented contour, but has a different contour. This contour of the curve section of the stopper element 26 cooperating with the roller 34 during the movement cycle is configured, for example, with an irregular curve, according to which the movement of the stopper means 11 as a whole and the stopper element As a result of the superposition with 26 motions, the desired motion profile is formed. Thus, for example, a movement of the stopper surface 12 located on the stopper element 21 with a constant movement with respect to the tangential direction, or a movement with at least a partially reduced velocity may be necessary and / or formable. It may be. On the other hand, the line of motion can be affected, for example, a substantially straight, possibly tangential, or tilted movement may be desired and / or formed. . Thus, the contour of the stopper element 26 formed with respect to the special requirements provides a large room for optimizing the movement of the stopper surface 12 which is effective for alignment.

The relative motion of the structure along a straight movement path B _R, the stopper element 21, for example via a linear guide 38, the frequency of the free end of the arm 22, i.e. are disposed in the head region. For example, the stopper means 11 configured as a gauge lever 11 is arranged on the shaft 14 so as not to rotate relative to it, for example by means of a clamp coupling part 39. In this case, the clamp coupling part 39 is preloaded by a spring element, for example a compression spring. May be energized.

  The device 09 arranged corresponding to the cylinder 07; 08 may be configured as a pure stopper device 09 or in a preferred variant as a stopper and gripper device 09. In the latter case, the stopper means 11, in particular the stopper element 21, may preferably be provided with a gripper element 36, for example a gripper tip 36, which protrudes beyond the stopper surface 12 in the tangential direction. In addition, when the stopper element 11 is lowered, the stopper element 11 is pressed against the printed material sheet 01 in contact with the stopper surface 12. However, alternatively or additionally, one or more grippers 37 are provided on one shaft that is provided axially spaced apart or separately on the same shaft 14 and is forcibly driven in a similar manner. Alternatively, the gripper 37 may be provided with a holding function instead of an alignment function, for example, unlike the stopper means 11 with an additional gripper tip 36 in some cases.

  In the following, the function and movement of the stopper means 11 will be described on the basis of the continuous instantaneous recording in the case of the stopper means 11 comprising a gripper tip 36 and an additional gripper (FIGS. 6a to 6). 6d). In that case, at the relevant location, a possible difference in the case of a configuration as pure stopper means 11 without the gripper tip 36 is suggested. The description will be made with an example of a cylinder 07 configured as a printing unit cylinder 07, but it is also applicable to another cylinder 08 provided with a stopper device 09 arranged on the transport path.

The rotational direction D of the cylinder 07 (08) is assumed to be counterclockwise in the configuration shown, for example, as can be seen from FIG. 6a. Similarly, for example, a cam disk 19 that cooperates with the roller 18, a shaft 14 that supports the stopper means 11, a (pure) gripper 37 on the front side, an arm 22 that is partly hidden and configured as a gauge lever 11, A stopper means 11 having a stopper surface 12 with a stopper element 21 which has a stopper surface 12 and is capable of relative movement in a straight line in the configuration shown, as well as in the configuration shown in FIG. (See, for example, FIG. 6a). The zero position L ₀ is indicated at a position where the moving track B _T of the panel 01 is in contact with the trunk circumference. The cylinder 07 (08) is at the zero position L ₀ when the effective stopper surface 12 matches the zero position L ₀ .

The contour of the cam disk 19 and the connection of the stopper element 21 to the cylinder 07 (08) are in harmony with each other, so that after the delivery of the preceding panel 01 during the movement phase of the cylinder 07 (08). Before contact with the next panel 01 to be supplied, the gauge lever 11 is moved further out of the circumferential surface by a first movement, in particular by rotation, and the stopper element 21 is moved in the second movement. Thus, the component directed in the direction opposite to the rotation direction is brought to a position further retracted from the trunk circumference. Stop surface 12, by which, in large before the zero position L _0, for example, at angular positions of the front 65 ° to 55 ° in zero position L ₀ alpha, are already provided in the moving trajectory B _T. That is, the stopper surface 12 reaches the moving track B _T of the panel 01 at an angular position α of 65 ° to 55 °, for example (see, for example, FIG. 6a). When the stopper means 11 additionally has a gripper tip 36 and the stopper means 11 is to be used as the gripper 37, the stopper means 11 should pass through the moving track B _T at the gripper tip 36 and receive it. moves to the upper height of the panel 01, in a subsequent course, the example panel 01 of the mobile track B _T against e.g. 2 ° only to 4 small angle δ of minute ° inclined linear motion trajectory B over _G For example, it approaches a point positioned in alignment with the zero position L ₀ , spaced from the waistline by the thickness of the panel 01. This movement tilted with respect to the panel movement is again achieved by the interaction of the first movement and the second movement. When the stopper means 11 is configured without a gripper function, inclined motion movement trajectory B _T of the movement by the track straight movement path parallel to the B _T, preferably the panel 01 of the panel 01 The above exercise may be substituted.

In order to ensure good and quiet guidance of the panel 01, the movement of both the stopper means 11 and the stopper element 21 and the phase and the transport speed of the transport device 04; As a result, the first contact (L _K ) between the stopper surface 12 and the edge 13 running on the front side of the substrate panel 01 as a result is as early as possible, eg already at the zero position. Before L ₀ , for example, it is realized at an angular position β of the cylinder 07 (08) of at least 20 °, preferably at least 30 °, in particular 35 ° to 45 ° (about 40 ° in the case of FIG. 6b). At the latest, the synchronized phase shift starts from the first contact, and in the synchronized phase shift, the stopper surface 12 acting as a stopper moves on the straight motion trajectory inclined or parallel to the travel trajectory B _T of the panel 01. It moves along the trajectory B _T at a speed substantially equal to the peripheral speed of the cylinder 07 (08), for example.

When the zero position L ₀ is reached by the stopper surface 12, the gripper closure of the gripper tip 36 and / or additionally arranged one or more grippers 37, possibly also at the same time, is preferably performed simultaneously. Arise. At this position, that is, at the zero position L ₀ , the stopper means 11, together with the stopper element 21, is preferably located at a predetermined relative position with respect to the cylinder 07 (08) and / or the moving track B _{T of the} panel 01. since, straight movement path B _R is approximately tangential to (e.g. ± 5 °, in particular with a maximum deviation of up to ± 3 °) cylinder 07 (08), and / or the movement trajectory B _T of the panel 01 It extends along (see d in FIG. 6).

  In order to clarify the mechanism and its function, FIG. 7 shows a schematic for the cylinder angular position and for the movement of the stopper means 11 and the stopper element 21 relative to the movement of the substrate sheet 01 to be fed. A supply diagram is illustrated.

In this example, the definition of the position of the printing material sheet 01 approaching is set, and according to this, the zero point of the printing material sheet 01 is at the position of the zero position L ₀ with respect to the cylinder 07; Or it will be located in the contact point of the tangential direction of the to-be-printed sheet 01 conveyed, and this is repeated every 360 degrees in the angle position of cylinder 07; 08. In the case shown in the figure, the approaching substrate sheet 01 approaching is conveyed at a constant speed, for example, while the stopper means 11 is still in the stationary phase _Pr . In this angular range of the cylinder 07; 08, the entire stopper means 11 is in the entered position and the stopper element 21 is in the initial position. In the initial position, the stopper element 21 is in a position in which the arm 22 is retracted, e.g. extending the arm 22 and / or located away with respect to the pivot axis. During the stopper element 21 is in its rest phase Z _r, located in relatively the first position relative to the arm 22 from a first position, the stopper element 21 contacts example the edge 13 which runs front / or after work during phase P _a, cylinder 07; relative to the arm 22 in the direction of rotation D of 08, a second position spaced relative to the first position in the rotating direction D in the circumferential Can exercise.

The first movement, for example the rotation of the stopper means 11 as a whole, and the second movement, i.e. the relative movement of the stopper element 21 with respect to the arm 22 of the stopper means 11, are simultaneous and temporally or angularly as described, for example. May be shifted from each other. An angular position or time point (position) where at least one of both elements is at least at position L ₁ where the arm 22 is moved from its rest position by a corresponding drive mechanism, for example based on the above-mentioned movement association L _1, with L _2), the work phase P _a of the stopper unit 09 begins. In the work phase P _a, in particular stopper means 11 configured as a gauge lever 11 is retracted to the rest position, i.e. from a first position closer to the axis of rotation at its free end, a first drive mechanism The first motion that is triggered results in a second position that has been withdrawn, ie at its free end, far from the axis of rotation with respect to the cylinder 07; 08. At the same time or offset from this, the stopper element 21, in particular configured as a gauge (front) 21, is withdrawn in the rest position, ie from its first position farther from the swivel axis at its free end. A second second movement, in particular a linear movement, caused by the second drive mechanism 23, retracted with respect to the arm 22 and / or located further forward in the rotational direction D with respect to the circumferential direction and / or on the pivot axis It is brought to a second, closer position.

During the working phase P _a, at a particular angle position beta, the stopper element 21, the first contact L _K between the substrate sheet 01 may occur, in particular configured as the substrate panel 01. This contact can, for example conveying device 04 which is configured correspondingly; by 06, at least until the zero position reaches the L _0, angle or time after suitably is further maintained, for example, to a separated position L _a. In other words, at least a portion of the working phase P _a, in particular in contact with the substrate sheet 01, the stopper element 21, with at least one motion component, cylinder 07; viewed in the circumferential direction of 08, forward in the arm 22, And / or move in the direction of movement of the substrate 01 relative to the circumference of the cylinder.

If the stopper element 11 has a gripper tip 36 and / or if an additional gripper 37 is provided, this is closed at the latest when the zero position L ₀ is reached.

The contact with the substrate sheet 01 and possibly the closing of the gripper is, in principle, just zero by the rotation of the gauge lever 11 returning to the rest position by the first drive mechanism after reaching the zero position L _0. It may be released again when the position L ₀ is reached. In this case, the gauge 21 may be moved to the initial position at the same time or shifted. In one embodiment described, the arms 22 and gauge 21, prior to the position to its rest position P _r is returned to the initial position until the beginning of a subsequent working phase P _a for the remainder of the cylinder rotation, the zero position L ₀ After passing, it stays at the end position occupying the range of the zero position L ₀ over a predetermined angle range of 10 ° to 40 °, for example.

  As already suggested, a cylinder 07; 08 provided with a stopper device 09 is a supply device (not shown) such as a stack supply unit (the stack supply unit can supply the substrate sheet 01 to be processed to the conveyance section. And a discharge device (in the discharge device, the processed printed material sheet 01 is carried out through the conveyance section), one or more may be provided on the conveyance path.

  In a particularly preferred embodiment, at least one printing section cylinder 07 (24) forming a nip position of at least one printing section 02, in particular the offset printing section 02, is provided with the above-described stopper device 09, for example the stopper and gripper device 09. It is comprised as the cylinder 07 (24) with which it is provided. This cylinder cooperates with another cylinder 24 (07) that forms a nip position to form a nip position that serves as a printing position. Another cylinder 24 (07) is configured as a printing blanket cylinder 24, in particular as a rubber blanket cylinder 24, for example in the case of suitable offset printing. In the case of direct printing, the second cylinder 24 may be configured as a plate cylinder. In the case of the second cylinder 24 and the offset printing unit 02, a third cylinder 42 having a plate, for example, the plate cylinder 42, particularly the printing plate cylinder 42, cooperates (see FIG. 8). The plate cylinder 42 and an inking device (not shown), for example an inking device, cooperate in the usual manner. In the case of wet offset, the plate cylinder 42 and a dampening medium application device, for example a dampening device, cooperate. The printing blanket cylinder 24 and the plate cylinder 42 are located on the ink path and thus form a printing cylinder 24; 42 for guiding the ink.

  The device 09 may in principle be provided on one of the two printing cylinders 07; 24 forming the printing position. In the case of the printing unit 02 that prints the substrate sheet 01 on one side, one of the two printing unit cylinders 07; 24 that forms the printing position, for example, the first cylinder 07 is an impression cylinder 07 or a receiving cylinder (pressure receiving cylinder). The first cylinder 07 serves as a receiving part for another printing part cylinder 24 for guiding the ink, for example a rubber blanket cylinder 24 or a transfer cylinder 24. In this case, the device 09 may in principle be provided in the printing unit cylinder 24 or the plate cylinder 07 for guiding the ink. Preferably, the device 09 is provided on the plate cylinder 07 in the case of the single-sided printing unit 02.

  In the case of the printing unit 02 that prints the substrate sheet 01 on both sides, the first cylinder 07 forms, for example, a second transfer cylinder 07, and the second transfer cylinder 07 is a second transfer cylinder (not shown). Work with the plate cylinder. In this case, one of the two transfer cylinders 07; 24, preferably the transfer cylinder 07 arranged below the movement trajectory of the substrate sheet 01, may comprise a device 09.

  The device 09 provided in the printing unit cylinder 07 (24) is preferably configured as a stopper and gripper device 09.

  In another preferred embodiment, a cylinder 08 arranged on the conveyance path, for example, before the entrance area of the processing unit 02; 03 or in the entrance area is provided with the stopper device 09 described above. Preferably, the cylinder 08 disposed in front of or in the inlet area corresponding to the processing unit 03 configured as the coating unit 03 is configured as a supply cylinder 08 or a supply drum 08 provided with a stopper device 09. Has been.

The supply cylinder 08 itself is, for example, as a receiving part as a functional part, and is not involved in the specific processing of the printing material sheet 01, and is aligned and / or processed, for example, downstream on the downstream side. Used to supply The supply cylinder 08 is preferably arranged on the lower side of the printing material sheet 01 guided on the moving track B _{T. In a} mode not shown, the supply cylinder 08 is surely loaded via the printing material sheet 01. For wearing, it may cooperate with a roller or a plurality of rollers as receiving parts.

  In one embodiment, not shown, the supply cylinder 08 is provided with means for increasing friction in at least one circumferential area following the device 09 during operation, for example, the loading force and thus the friction force between the substrate sheet 01 and the peripheral surface. Means 43, in particular negative pressure P- or preferably means 43 for generating a magnetic force.

  For example, in the preferred case of a metal substrate sheet 01, for example a metal panel or sheet metal panel, it is configured as a magnet segment 43 in the area of the peripheral surface, for example directly or at a maximum of 45 °, in particular 30 ° apart. Followed by the device 09, which extends over an extremely large circumference, for example at least 20 °, preferably at least 30 °. The magnet segment 43 may include one or a plurality of magnets that directly cooperate with the substrate to be transported 01, or one or a plurality of magnets that magnetize the peripheral surface of the cylinder 08 from the inside. In this case, the substrate sheet 01 to be conveyed is attracted to the peripheral surface by a magnetic force.

  In an alternative embodiment in which a non-magnetizable substrate sheet 01, such as a plastic sheet, wood sheet, cardboard or sheet of paper, is to be attracted to the cylinder 08 by means 43 for increasing friction, the means 43 is, for example, a negative pressure P−. In this case, an opening capable of supplying the negative pressure P− from the inside is provided on the peripheral surface, for example, by the device. In this case, the substrate sheet 01 to be conveyed is attracted to the peripheral surface even by the negative pressure P.

  In the described aspect including the means 43 for increasing the frictional force between the substrate sheet 01 and the peripheral surface, in principle, the drum or the pressure roller that exerts the above additional pressing action is provided, although not necessarily. Good.

  In one preferred embodiment, the supply cylinder 08 is, for example, in front of or in front of the entry area of the processing tool of the printing unit 07; 24 or in particular the cylinder 47, for example the coating cylinder 47, of the downstream processing unit 03 (02). According to this, the supply cylinder 08 is a post processing tool (positioned downstream) on the transport path upstream of the processing tool up to the length of the printed sheet 01. Is spaced from.

  For example, in the aspect shown in FIG. 9, the cylinder 08 is located on the upstream side of the coating unit 03, that is, in the entrance area. The coating unit 03 includes, for example, a first cylinder 46, for example, an impression cylinder (pressure receiving cylinder) 46, and the first cylinder 46 serves as a receiving cylinder 47 configured as a second cylinder 47 as a receiving unit. Together, a nip position is formed. At the nip position, the substrate sheet 01 to be guided through can be applied by the coating cylinder 47. For example, the coating cylinder 47 provided with a rubber coating part receives paint to be applied from, for example, a form roller 48 that cooperates with the coating cylinder 47, and the form roller 49 itself includes, for example, a metering roller 49 of the paint supply unit. The required amount of paint is supplied via

  Means 52 for increasing the adhesion force between the supply cylinder 08 and the nip position of the coating unit 03 in the conveying path, and hence the frictional force between the printed sheet 01 and the peripheral surface, in particular negative pressure P- or preferably A roller 51 provided with means 52 for generating a magnetic force, for example, a guide roller 51 may be provided. This roller 51 preferably comprises means 52 around the entire circumference. Preferably, the roller 51 is placed behind the supply cylinder 08 at an interval which is the length of the substrate sheet 01 to be processed at the maximum on the conveyance path.

  In a third embodiment not shown, the cylinder 08 may be provided as a supply cylinder 08 between the two transport section sections of the machine without a direct structural or functional connection. .

  For example, a frame is fixed between each conveying device 04; 06 and a cylinder 07; 08 (24) provided with a stopper device or a stopper and gripper device 09 (see FIGS. 1 and 2, FIG. 12 and FIG. 13). Although not shown in the drawing, there are provided guides 44 each equipped with a guide 44, for example a guide element 45 comprising one or more parts, for example a slide plate 45, via the guide element 45. The substrate sheet 01 is supplied to the cylinder 07; 08 (24) through the conveying device 04; 06 (see, for example, FIGS. 8 and 9). The guide 44 is used for horizontal alignment and support, and may optionally include a device (not shown) for lateral alignment of the printed sheet 01.

  For example, a machine comprising at least one printing unit 02 comprises, in one aspect, at least one printing unit comprising a printing unit cylinder 07 (24) having a stopper device 09. In one refinement, a cylinder 08 comprising the above-described stopper device 09, which is configured as a supply drum 08, is additionally provided on the transport path.

  For example, in an alternative embodiment of a machine with at least one printing unit 02, a supply cylinder 08 with a stopper device 09 is arranged in the entrance area before the printing unit 02. In this case, the printing unit cylinders 07; 24 that form the nip positions may be configured without the stopper device 09.

  For example, a machine with at least one coating part 03 has, in one aspect, at least one supply cylinder 08 with a stopper device 09 arranged in the entrance area in front of the coating part 03.

  On the machining path of the machine, in an improved form, at least one printing part 02 having a printing part cylinder 07 (24) provided with a stopper device 09 and at least one coating comprising a supply cylinder 08 placed in the above-mentioned form. Each part 03 may be provided.

  In the example of FIGS. 8 and 9, the transport device 04; 06 placed in front of the cylinder 07; 08 having the stopper device 09 is an appropriate mode of the transport device 04; 06 for easy understanding of the drawings. As a representative, there is shown not only the suggested rear side pressing member 15 but also means 25 for increasing the mounting force, which is indicated by a broken line. Preferably one of both of these means may be omitted, in which case the use of means 25 for increasing the mounting force is preferred.

The aspect of the stopper 09 comprising the stopper means 11 for performing the first movement and the stopper element 21 for performing a translational relative movement in the stopper means 11 is that of the stopper surface 12 that cooperates with the edge 13 that runs on the front side. Used for “pre-control”. This pre-control serves to provide as little bounce and / or as little acceleration as possible to the stop surface 12 for registering as intended. For this purpose, according to the description of the stopper device 09, the movement of the stopper surface 12 that proceeds in the direction of the moving trajectory B _T at a predetermined, for example, at least synchronous stage is realized. However, this stopper surface 12 forms a well-defined “hard” stopper at any point during cooperation with the edge 13. The supply of the edge portion 13 that travels on the front side of the printing material sheet 01 to the stopper surface 12 of the stopper device 09 is performed by friction coupling to the printing material sheet 01 by the transport device 04; Of the frictional force) and / or by the driving force exerted on the shape coupling (the shape coupling means the coupling by the geometric relationship between members such as fitting or meshing).

  The first embodiment of the above-described configuration, comprising the stopper means 11 that mainly performs the movement in the radial direction, and the stopper means 11, particularly the stopper element 21 that mainly performs the relative movement in the tangential direction, is configured as described above. Pre-controllable stopper device 09 and / or a cylinder 07; 08 (24) with such a stopper device 09 and / or transporting with such a cylinder 07; 08 (24) of a machine for processing sheets The section may in principle be provided to cooperate with a transport device 04; 06 that exerts a propulsive force on the substrate sheet 01, which is arbitrarily configured.

  However, in one particularly preferred refinement, the stopper device 09 or the cylinder 07; 08 (24) with the stopper device 09 limits the force of the conveying device 04; 06 acting on the substrate sheet 01 for feeding. It is provided to cooperate with the following aspects comprising means for: On the contrary, the following transport device 04; 06 is provided with a means for limiting the feed of the circulating travel means 05, in particular, the transport device 04; Further, it may be placed in front of a stopper device 09 arbitrarily configured on the transport path, in particular, a cylinder 07; 08 (24) including the stopper device 9 arbitrarily configured. However, in a preferred embodiment, the transport device 04; 06 includes the stopper device 09 including the stopper element 11 that performs the first motion in the above-described form and the stopper element 21 that performs the relative motion in the stopper element 11. It is placed in front of the cylinder 07; 08 (24).

  The transport device 04; 06 is configured to include means 53; 54; 67; 56; 81; 82; 83; 84; 98 that limit the force acting on the substrate sheet 01 for feeding. Regardless of the configuration of the transport device 04; 06 and / or the form of propulsion provided, these means 53; 54; 67; 56; 81; 82; 83; 84; 98 may be realized in various forms. . By means 53; 54; 67; 56; 81; 82; 83; 84; 98, the thrust to be exerted on the printed sheet 01 via the conveying device 04; 06 against the resistance formed by the stopper device 09 Can be limited at least temporarily, eg, to a predetermined threshold. When the threshold is exceeded, the reaction action of the means 53; 54; 67; 56; 81; 82; 83; 84; 98 begins, whereby the force on the substrate sheet 01 fed to the stopper device 09 is no longer No more increase.

  In the aspect based on the shape coupling of the transport device 04; 06 provided with the stopper 15, for example, the rear pressing member 15, which is disposed on the circulation traveling unit 05 and acts on the end portion of the substrate sheet 01 that travels on the rear side. In order to limit the feed force, the stopper 15 can in one simple variant be transported to the corresponding tensioning means, for example to the belt 05 itself or to a belt or chain that also comprises the rear pressing member 15 and also circulates. It may be supported spring-elastically in the direction opposite to the conveying direction T present in the device 04; 06. In this case, as a means 53 for limiting the propulsive force, for example, a spring element 53 (only suggested in FIG. 1), for example, a compression spring 53, may be provided. In order to limit the feeding force, it may be supported elastically in a direction opposite to the conveying direction T relative to the belt running. The same applies to the spring element 53, which is configured as a tension spring, in a correspondingly opposite arrangement. However, in this aspect of force limitation, an undesired acceleration can occur during static friction “peeling” due to the relative movement between the belt 05 that is subsequently conveyed and the printed material sheet 01 that is elastically deformed.

  Between the circulating travel means 05 and the substrate sheet 01 using means for increasing friction (for example, as suggested by way of example in FIG. 2), for example using means 25 for generating negative pressure P− or magnetic force. In one embodiment of the transport device 04 having transport based on frictional or force coupling, the strength of the means may be adjusted or the strength of the means may be adjusted in a simple variation to limit the feed force. It may be adjustable, so that the threshold of static friction thus adjusted by the strength is exceeded from the specific resistance caused by the contact with the stopper means 11 when the substrate sheet 01 is conveyed. Is done. However, this can lead to undesired acceleration and / or displacement again based on the rapidly changing coefficient of friction at the point where static friction is exceeded.

  In a preferred embodiment of the transport device 04; 06 capable of restricting the feeding force, the circulating traveling means 05 for transporting the printing material sheet 01 in a frictional coupling type or a shape coupling type, for example, the printing material sheet 01 is conveyed in a frictional coupling type. The feeding of the belt 05 or the pulling means (for example, a belt, a chain, or a belt) including the rear side pressing member 15 is operated at least in the conveyance section 55 cooperating with the substrate sheet 01 in the direction opposite to the conveyance direction. Accordingly, it is configured flexibly, for example, in a spring damping type and / or in a moment limiting type. For example, in the first mode, the driving device itself for driving the circulating traveling unit 05 can be elastically deformed when the resistance increases in the direction opposite to the conveying direction T, or the resistance is related to the resistance. It is flexible from a predetermined threshold value, or in the second aspect, the belt extending portion or the circulating travel means extending portion can be realized by being elastically deformable when the resistance increases in the direction opposite to the conveying direction T. is there. In this case, the elastic deformation or deflection according to the operation must be executable without being restricted by means for restricting the feed. Means 54; 67; 56; 81; 82; 83; 84; 98 for restricting the feed of the circulating travel means 05 are, for example, means 54; 67; 56; 81; 82; 83; 84; It is configured to allow (without breakage) at least one minimum stroke between a belt feed that is impaired and a belt feed that would be expected if there were no failures. This minimum stroke is for example several millimeters, in particular at least 2 mm, preferably at least 5 mm. In this case, at least the elastic deformation or deflection in accordance with the operation results in a few millimeters, for example relative to an unobstructed movement, at least in the belt feed of the conveying section 55 cooperating with the substrate sheet 01. This is done by a stroke caused by at least a temporary delay of the circulating travel means 05 up to at least 5 mm. The minimum stroke possible in response to operation means a deflection that is not damaged and is not in the range of undesired sustained material deformation.

  Accordingly, in this aspect, the force acting on the substrate sheet 01 for feeding is limited when, for example, the driving device of the pulling unit or the extending unit of the pulling unit itself increases in resistance in the direction opposite to the conveyance direction T. This is done by being able to bend, for example elastically deformable or in the case of a drive device for example “sliding out”.

  In a preferred embodiment of the conveying device 04; 06 based on the frictional coupling between the circulating travel means 05 and the substrate sheet 01, the circulating travel means 05, for example, the belt 05 is fed in accordance with the operation in the above form. For example, a spring damping type and / or a moment limiting type may be used. In this case, the static friction between the circulating travel means 05 and the substrate sheet 01 to be transported is not elastically deformed during operation. Less than the force to be generated or induced, especially chosen so that the force coupling is not yet released at least within the minimum stroke. In other words, the spring forces or expansion forces of the means and means 54; 67; 56; 81; 82; 83; 84; 98 for increasing friction are adjusted in harmony with each other, so that they are opposite to the conveying direction T. The acting static frictional force between the circulating running means 05 and the substrate sheet 01 to be conveyed is larger than the force that causes elastic deformation or deflection below the minimum stroke. The edge 13 of the substrate sheet 01 traveling on the front side is pressed against the stopper 09 placed on the transport path by the transport device 04; 06 with a force exceeding the threshold, and thus the circulation travel unit 05 Since the feed is elastically deformed accordingly, the force acting on the substrate sheet 01 for feed is limited. As a result, the force acting on the printing material sheet 01 can be restricted or restricted between the stopper 09 on the one hand and the conveying device 04; 06 acting on the friction joint on the other hand.

  A suitable one relating to a conveying device 04; 06 based on shape coupling, provided with a stopper 15, for example, a rear pressing member 15, disposed on the circulation traveling means 05 and acting on an end portion of the printed sheet 01 traveling on the rear side. In one aspect, the feed of the circulating travel means 05 including at least one rear pressing member 15 may be configured flexibly according to operation in the above-described form, for example, a spring damping type and / or a moment limiting type. In this case, the rear side pressing member 15 is disposed in the circulation traveling means 05 in a fixed position with respect to the circulation traveling direction or along the transport direction T, and is configured to be inflexible. When the edge portion 13 traveling on the front side of the substrate sheet 01 is pressed against the stopper device 09 placed on the conveyance path by a conveying device 04; 06 with a force exceeding a threshold value, the circulating traveling means 05 feeds. Is elastically deformed in response to this, so that the force acting on the substrate sheet 01 for feeding is limited. As a result, the force acting on the printed sheet 01 can be restricted or restricted between the stopper device 09 on the one hand and the conveying device 04; 06 acting in a frictional coupling manner on the other hand.

  Below, the suitable aspect regarding the conveying apparatus 04; 06 which can be restrict | limited regarding feed force is demonstrated. In a preferred embodiment, the feed of the circulating travel means 05 for transporting the printing material sheet 01 in a frictional coupling type or a shape coupling method is at least opposite to the conveying direction in the conveyance section 55 cooperating with the printing material sheet 01. It is configured flexibly according to the operation, for example, in a spring damping type and / or in a moment limiting type. An example of a flexible configuration regarding the feeding of the circulating travel unit 05 has been described based on one preferred mode having a force action based on frictional coupling between the circulating travel unit 05 and the substrate sheet 01. Similarly, these examples may be applied to the conveying device 04; 06 having a shape-coupled force action between the stopper 15 disposed in the circulating travel unit 05 and the substrate sheet 01. In this case, means for increasing the frictional force may be omitted. In the embodiment having a force action based on the frictional coupling between the circulating running means 05 and the substrate sheet 01, the means 25 for increasing the friction may be preferably provided, or in some cases, for example, a metal (for example, at least 0) For example, in the case of a high-basis weight substrate sheet 01 made of a metal having a thickness of 0.5 mm, it may be omitted.

  In the first group of the embodiment of the embodiment of the transport device 04; 06, which is configured to be flexible in at least the transport section with respect to the feeding, in the first group of the embodiment, the circulating travel means Means 54; 67; 56 for a feed limit of 05 are provided.

  In the first aspect of the first group, the drive between the drive means 56, for example the drive motor 56, and the member 58, for example the output member 58, which cooperates with the circulation travel means 05 for the feed of the circulation travel means 05. In at least one transmission member 57 of moment, the drive train is not completely rigid, but is, for example, configured elastically in the range of a minimum spring stroke different from zero. The minimum spring stroke set in accordance with the operation is the minimum stroke (swing) of the circulating travel means 05 that occurs in the transport section 55 between the uncirculated circulating travel means feed and the circulating travel means feed blocked by the increase in resistance. Associated with. In the embodiment of the transport device 04; 06 based on (pure) frictional coupling, a spring-elastic deflection threshold is preferably set. This threshold is related to the static frictional force present between the substrate sheet 01 and the circulating travel means 05 with or without means for increasing friction in the (pure) friction-coupled transport mode. It is adjusted or selected, whereby the edge 13 running on the front side comes into contact with the stopper device 09, which leads to a static friction resistance, that is, a critical for “friction” of static friction. Prior to this, a threshold has already been reached that causes the deflection of the circulating travel means feed.

A first variant of the first aspect of the first aspect is that in the drive train, two members 58; 59 that transmit rotational motion in the drive train are in the range of spring travel in the circumferential direction with respect to rotational transmission. It is connected via a flexible transmission member 57 inside. In this case, the transmission member 57 is provided with a spring-elastically acting element 54, for example a spring element 54 or an aerodynamically spring-elastic element 54 as the means 54 for feed restriction. This element 54 is arranged between a plurality of stoppers 61; 62 acting, for example, in the circumferential direction of both members 58; In this case, in the direction of rotation present during operation, the torque is preferably against the spring force, i.e. from a member 58 which is closer to the drive side, via the element 54 acting in a spring-elastic manner. Is transmitted to the member 59 closer to the output side. Through selection of the stiffness or spring constant of this element 54, the “hardness” or deflection of the feed limit may be affected. Preferably, the connecting portion or transmission member 57 acting in a spring-elastic manner is configured by preloading at a predetermined zero position L ₀ with a force different from zero, for example, setting a threshold value for elastic deformation or deflection. Yes. For this purpose, the member 58; 59 is provided with another stop 63; 64 acting in the circumferential direction, the stopper 63; 64 cooperating to resist the force of the preloaded spring element 54. Relative position between the stoppers 63; 64 in which the spring element 54 is interchangeable with another spring constant spring element 54 and / or can be changed with respect to the spring characteristic curve and / or forms a zero position L ₀ Can be changed, the threshold value for elastic deformation of the drive device and thus the threshold value for elastic deformation of the feed restriction of the circulating travel means 05 can be changed. The zero position L ₀ is, for example, in an operating state in which no load is applied, for example in a stationary state or in particular in the transporting stage, where the edge running on the front side in the stopper device 09 with an unacceptably high force There are no obstacles to increase the resistance beyond the allowable threshold due to 13 abutments. When the threshold value of the contact force specified by the spring element 54 or the transmission member 57 including the spring element 54 is exceeded, the spring element 54 is elastically deformed. This elastic deformation gives rise to a stroke between the actual feed of the circulating travel means 05 and the feed expected in the same movement stage if there are no obstacles. The maximum possible stroke in the area of the transport section 55 is, for example, the maximum possible spring stroke specified by, for example, the stoppers 61; 62; 63; 64 and / or the spring element 54, or preferably a preloaded spring element. 54 or the elastic deformation angle ε of the transmission member 57.

  In the preferred configuration of the first variation (see, for example, FIGS. 10 and 11), the transmission member 57 acting in a spring-elastic manner is coupled to a shaft 66, for example, the drive shaft 66, so as not to be relatively rotatable on the drive side. And the output member 58 is entrained between the shaft 66 and a drive disk 58 that is preferably rotatably supported on the shaft 66 (eg, via a rolling bearing) and preferably forms an output member 58. (See, for example, the open view of the drive wheel 69 of FIG. 10 in FIG. 11). Preferably, the transmission member 57 is between a drive inner ring 59 as a member 59 that is coupled to the shaft 66 so as not to be relatively rotatable, and a drive disk 58 that is disposed on the shaft 66 so as to be relatively rotatable. In this case, the drive disk 58 may be configured in the form of one component unit as the drive wheel 69 biased by the torsion spring force together with the drive inner ring 68 and the transmission member 57 that connects both members. The spring element 54 is preferably configured as a pressure medium cylinder 54 in which a compressible fluid, for example a gas or a gas mixture, is closed on the one hand to the cylinder and on the other hand to a piston that closes the fluid chamber. A spring-elastic action is produced during this period.

  In the first variation, the circulating travel unit 05 is configured as, for example, a belt 05 that cooperates with the substrate sheet 01 to transport it. In this case, the conveyance in the conveyance direction T is performed based on friction, for example, not by the rear pressing member 15. In order to increase the friction, means 25 for increasing the frictional force mentioned above, for example a magnet 25, or preferably a negative pressure chamber 25 as described, may be provided. For example, the means 25 configured as a negative pressure chamber 25 may in principle be configured to attract the substrate sheet 01 at any position in the transport section 55 in the horizontal and vertical directions. The means 25 may simply be provided in one length section of the transport section, in which case the distance to the stopper device 09 is preferably smaller than the length of the printed sheet. In a preferred embodiment, the means 25 are arranged just below the belt 05 in the transverse direction, so that the substrate sheet 01 is attracted to the belt 05 extending between the substrate sheet 01 and the means 25. It is done. In this case, the belt 05 may preferably be configured as a so-called vacuum belt 05 in the form of a holed belt 05, that is, a plurality of belts 05 penetrating the belt 05 from the lower side toward the substrate sheet 01 to be conveyed. You may have a structure with a hole provided with the hole 71 of this. A negative pressure P− can be supplied to the hole 71 from the side opposite to the substrate sheet 01 to be conveyed using, for example, a means 25 configured as a negative pressure chamber 25. This may be applied to the configuration of the negative pressure chamber 05 which is moved (see below) and has a fixed frame configuration.

  In one, a plurality or all of the forms and variations of the transport device 04; 06, via a frictional force or shape coupling that transports the substrate sheet 01 at an interval transverse to the transport direction T. A plurality of, in particular, two circulating running means 05, in particular, a belt 05, for specifying a predetermined feed of the printing material sheet 01 may be provided. The one or more belts 05 extend in the transport direction T during operation in the transport area, ie in the area cooperating with the substrate sheet 01, in this case a particularly flat transport area, for example, , Defined by means 81, 82, for example diverting elements 81; 82, in particular diverting rollers 81; 82, in the conveying direction T, which are at least partly wound by the circulating travel means 05. Yes. With respect to the belt guide of the circulating travel means 05, the guide rollers 65 extending in particular flat are defined by these turning rollers 81; 82. In the guide section 65, the circulating travel means 05 cooperates with the printed sheet 01. Can work.

  In addition to these circulation travel means 05, another circulation travel means 72 may be provided in order to fix the printing material sheet 01. The other circulation travel means 72 is not shown in detail here. It circulates and travels in parallel with at least one circulating travel means 05 that specifies the feed via the drive means and the turning means. The additional circulating travel means 72 may comprise a stopper 76, for example a front stopper 76. The substrate sheet 01 to be conveyed may be brought into contact with the stopper 76 via the conveying device 04; 06. The substrate sheet 01 is, for example, several times via, for example, at least one circulating belt 75 upstream of the same transport device 04; 06 or a front transport device different from the same transport device, for example as well. When the sheet is delivered to the conveyance section 55 having the circulating travel means 05 arranged immediately before the stopper device 09 by the conveyance section 74 that conveys the minutely or quickly, the stopper 76 is used, for example, for the front application of the printed sheet 01. It is done. Due to the higher transport speed of the transport section 74 placed in front and the front stopper 76 that is moved synchronously with respect to the circulating travel means 05, for example, the substrate sheet 01 is transported immediately before the stopper device 09. In the section, it is brought to a predetermined position with respect to the edge 13 running on the front side.

  In this or another aspect or variant, the drive device of the one or more circulating travel means 05 specifying the feed is optionally provided on a shaft 66 that directly supports one or more drive wheels 69. Via a coupling (see below) or via one or more transmissions 73 as shown, for example via a tensioning means transmission 73, means 56, such as driving means 56, only schematically shown, preferably May be driven or driven from a drive motor 56 arranged corresponding to the conveying device 04; 06 or possibly from a drive assembly via a corresponding drive coupling. In this case, the circulating travel means 05 for specifying the feed and the optional additional circulating travel means 72 are configured endlessly.

  In a second variant, not shown in detail of the first aspect of the first group, the deflection requires that the transmission member 80 itself, which transmits the rotational movement in the drive train, is in the form of a torsion bar spring. It is based on being configured flexibly (that is, soft with respect to torsion) in the range of the spring stroke (or elastic deformation angle ε). Thus, the shaft 80 arranged in the drive group of the drive device may be configured as the transmission member 80 acting in a spring elastic manner. In this case, the shaft 77 is configured in the form of a torsion bar spring.

  In a third variant, also not shown in detail, of the first aspect of the first group, a further transmission member 77, for example a tensioning means 77, arranged on the drive train, is attached to the spring with respect to its spatial extension. It may be supported elastically. In this case, for example, at least one elastic deformation roller (not shown), for example, spring elastically, is supported between the drive side and the output side, that is, between the input wheel 78 and the output wheel 79 in the tension means circulation travel. For example, the effective tension means length of the belt section traveling forward can be extended against the spring force by the elastic deformation roller, and as a result, at least temporarily, the above-described process of feeding the tension means can be performed. Achieved. The belt section traveling backwards is preferably provided with a corresponding elastic deformation roller, or vice versa.

  In a second aspect of the first group, a driving force introduced into the drive train on the inlet side by the drive means 56 and / or transmitted by the at least one transmission member 67 in the drive train, for example, Since the driving force in the form of torque to be applied can be limited with respect to a predetermined threshold, for example, the feed of the circulating travel means 05 is configured flexibly. In this case, for example, even if the resistance due to the contact of the edge portion 13 traveling on the front side with respect to the stopper device 09 increases, for example, torque corresponding to the threshold is introduced into the drive train of the circulating travel means 05 and / or In this drive train, it is transmitted to the circulating travel means 05.

  In the first variant of the second aspect of the first group (see FIG. 12), a drive train is provided between the drive means 56 and the circulating travel means 05 and the output member 58 that cooperates to drive it. A transmission member 67 configured as a connecting portion 67 is provided. The maximum torque that can be transmitted by the transmission member 67 is limited or can be limited to a predetermined threshold value. In this case, the connecting portion 67 configured in this way acts as means 67 for restricting the feed of the circulating travel means 05 in the above sense. The connecting portion 67 is preferably adjustable with respect to the height of the threshold, and is particularly configured to be adjusted steplessly preferably at least within the adjustment range. The threshold value of the torque is a static friction force that exists between the substrate sheet 01 and the circulating travel means 05 with or without means for increasing the friction in the (pure) friction-coupled conveyance mode. Is adjusted or selected with respect to it, whereby the contact of the edge 13 running on the front side with the stopper device 09 leads to a static frictional resistance by contact, i.e. critical to the "crack" of static friction. Prior to this, a threshold has already been reached which causes a deflection of the circulating travel means feed.

  As long as the connection part 67 restrict | limits torque transmission to predetermined, the connection part 67 may be arbitrarily comprised in principle regarding the principle of operation which forms the foundation. In an alternative embodiment, the connecting part 67 is configured as an electromagnetic coupling, in particular as an electromagnetic powder coupling. In an alternative embodiment, a connection 67 configured as a compressed air joint 67 may be used for this purpose.

  In the second variant of the second aspect of the first group (see FIG. 13), the drive means 56 configured as a drive motor 56 is configured to be limited with respect to the drive moment supplied by the drive motor 56. Yes. In this case, the drive motor 56 configured in this manner serves as means 56 for limiting the feed of the circulating travel means 05 in the above sense. Preferably, the drive motor 56 is configured as a particularly adjustable servo motor 56 that can be limited in terms of torque. Regarding the adjustment of the threshold for limiting the torque or the threshold for setting the driving torque, the above description regarding the threshold applies as well.

  In at least the transport section 55, the transport device 04 comprising the circulating travel means 05 configured flexibly with respect to feeding; in the second group of aspects of 06, the spatial circulating travel means extending portion or the circulating travel means guide is flexible. According to which at least one guide element 81; 82; 83; 84; 98, preferably two such guide elements 81; 82; 83; 84; 98 can be elastically deformed in the radial direction based on an increase in resistance that is opposite to the conveyance direction T, for example, due to the contact of the substrate sheet 01 with the stopper device 09, thereby at least Temporarily, the feed restriction of the circulating travel means 05 in the guide section 65 of the transport section 55 is caused. The guide elements 81; 82; 83; 84; 98 (possibly attached spring elements 94; 104) arranged flexibly or spring-elastically in this way in the above sense are fed, in particular Serves as means 81; 82; 83; 84; 98 to limit belt feed. Due to the elastic deformation, the feeding of the circulating travel means 05 is temporarily decelerated or further stopped at the conveyance section 55 cooperating with the substrate sheet 01 or the guide section 65 arranged corresponding to the conveyance section 55.

  The belt speed reduction that occurs in the transport zone or in the corresponding guide section 65 due to the feed limitation of the circulating travel means 05, i.e. resistance, is simply a guide element or deflection element 83 in the first mode of the second group. 84 elastic deformation. The elastic deformation does not affect the guide section 65 of the conveyance area of the circulation travel means 05, that is, the circulation travel means extension part or the belt extension part existing in the area cooperating with the printing sheet 01. When the length and position of the guide section 65 are not changed, the feed restriction is performed by a decrease in the circulating travel means speed or the belt speed in this section. In this case, such a decrease in speed is caused by elastic deformation at another position of the circulating travel means extending portion located outside the conveyance area. Preferably, each one spring element 83 is provided in the guide section 86 between the outlet-side turning roller 81 and the position of the belt drive, for example the drive wheel 69, and one guide element 84 is It is provided in the guide section 87 between the belt drive device, that is, the position of the drive wheel 69 and the turning roller 82 on the inlet side. As a result, one of the guide sections 86; 87, in particular the guide section 86 traveling in the front side with respect to the drive wheel 69, can be shortened by elastic deformation, while at the same time another guide section has a corresponding length. Can only be extended. Accordingly, the guide section 86 placed in front of the drive device is configured flexibly with respect to the length of the extended section. The transport carried out by the drive device for shortening does not act on the feed of the circulating travel means 05 in the transport zone or at least does not act completely, and at least partly, in particular a guide section 86 that travels in front of the drive device. Absorbed by deflection at 87;

In a first variant of the first aspect of the second group (see, for example, FIG. 14, FIG. 14 simply shows the extension part of the circulating travel means 05 and the guide together with the guide elements 81; 82; 83; 84, and Only the suggested drive wheel 69 is shown by way of example), a guide section in front of the drive wheel 69 and a guide section 86 in the rear of the drive wheel 69; The supported turning elements 83; 84, for example, the turning rollers 83; 84 are supported so as to be linearly movable in the radial direction. In particular, the diverting elements 83; 84 may be supported on a common support 88 such as a carriage 88 so as to be able to rotate, and the support 88 itself is arranged so as to be linearly movable with respect to a frame-fixed guide. Yes. Preferably, the carriage 88 is preloaded to one point of the frame fixing via a spring element not shown here, thereby cooperating with a guide section 86 running on the front side. A turning roller 81 turns this guide section 86 in a direction extending longer with respect to the shortest possible extension, and conversely, a change that cooperates with the guide section 87 running on the rear side. The directional roller 82 shortens the guide section 87 running on the rear side with respect to the longest possible extension. In a preferred refinement, a stop is provided which limits the linear movement against the spring force, by means of which the spring element increases the spring force already at the zero position L ₀ of the carriage 88 and is therefore resistant. A threshold different from zero for the displacement caused by the increase is established.

  In principle, both turning rollers 83; 84 may be supported in a linearly movable manner on the guide sections 86; 87, respectively, in the form described, independently of one another.

In a second refinement of the first aspect of the second group, not shown, the turning roller 81 cooperating with the guide section 86 running on the front side is supported by a pivotable lever 89. , According to which the diverting roller 81 turns the guide section 86 towards a longer extension part with respect to the shorter extension part that is feasible in an unloaded state. Thus, if the resistance is increased, for example by contact of the substrate sheet 01, the lever 89 thus resists a spring element 94 acting on the lever 89, for example a compression spring or a tension spring or a pneumatic force acting on the cylinder. Thus, the conveyance section 86 is moved to a position for shortening. Accordingly, in the guide section 87 traveling on the rear side, the turning roller 83 is supported spring-elastically, and according to this, the turning roller 83 has the length of the transport section traveling on the rear side. The length of the circulating travel means or the belt length released by turning the lever 89 from the guide section 86 traveling on the front side is extended. In a preferred refinement, a stopper 96 is provided which restricts the pivoting movement of the lever 89 against the spring force, so that the spring element 94 is already zeroed at the zero position L ₀ of the lever 89. Increases the different spring forces and thus establishes a threshold different from zero of the deflection caused by the increased resistance. The turning roller 84, which is spring-elastically arranged in the guide section 87 running on the rear side, may be configured in the form of a spring-supported belt tensioner.

  In the second mode of the second group, the elastic deformation of the circulating travel means guide is effected by at least one guide element or deflection element 81; 82. The guide element or turning element 81; 82 specifies the length and / or position of the guide section 65 corresponding to the transport area. Preferably, at least the outlet-side diverting roller 81 is movable with at least one component extending along the conveying direction T, and in particular resists the spring force of the spring element in the direction opposite to the conveying direction T. Flexible or spring-elastically supported.

In the first variation of the second mode of the second group (see, for example, FIG. 15), the diverting roller 81 on the outlet side is a lever 93 that allows the diverting roller 81 to rotate about a rotation axis 92. As described above, it is supported in an elastic manner. Lever 93, against the force of the spring element 94, rotatable from the zero position L _0, the position deflection roller 81 is located closer to the input side deflecting roller 82 with respect to the zero position L ₀ It is. Due to the elastic deformation, the entire length of the guide sections 65; 86 corresponding to the transport area and the forward extension portion of the drive unit is shortened, thereby reducing the speed at least temporarily acting in the transport area. As described above, the preloading of the spring element 94 can be adjusted by the corresponding arrangement of the stoppers 96, whereby a threshold value for inducing elastic deformation can be set. The guide section 87 traveling on the rear side is provided with a deflecting roller 84 which is also comparable to the above-mentioned configuration and is elastically supported. It is extended by the length of. Depending on the position of the drive wheel 69, the circulating travel means 05 can be one or more arranged in a fixed position in order to obtain the required elastic deformation force between the diverting roller 81 on the outlet side and the drive wheel 69. The guide element or the diverting element 95, for example, the diverting roller 95 may be used for guidance.

  In the second variation of the second mode, the diverting roller 81 on the outlet side is one lever of a lever 97 that can rotate around a rotation axis 92, unlike the above-described configuration. It is provided on the arm. In this case, another turning roller 98 that is partially wound around the second lever arm by the circulating travel means is provided. By rotating the lever 97, as described above, the entire length of the guide sections 65; 86 corresponding to the conveyance area and the forward extension portion of the drive unit is shortened. However, in this case, the S-shape around the turning rollers 81; The guide allows a greater reduction of the overall length in the comparable path of the exit-side diverting roller 81. The above description applies to the spring element 94, the stopper 96, and the turning roller 84 disposed in the guide section 87 running on the rear side.

  For example, in the third variation of the second mode shown in FIG. 17, the exit-side diverting roller 81 is supported so as to be linearly movable, particularly in parallel with the transport direction T. For this purpose, for example, a guide element 101 fixed to the frame, for example a guide pin 101, cooperates with a guide element 102 of the carriage 103, for example a slot 102 provided in the carriage 103, according to which the guide element 102 The carriage 103 that supports the diverting roller 81 can be moved in parallel with the transport direction T. The carriage 103 is also elastically deformable against the spring element 104, for example, the spring force of the compression spring in the illustrated configuration. In this case, the spring element 104 is supported by a stopper 106 fixed to the frame. Along with the movement of the carriage 103, the diverting roller 81 on the outlet side and the means 25 for increasing friction, which is also connected to the carriage 103, for example, configured as a negative pressure chamber 25, move. In order to supply the negative pressure P− to the friction enhancing means 25 configured as the negative pressure chamber 25, a connecting pipe piece 107 arranged on the frame may be provided. The connecting pipe piece 107 cooperates with the suction-side opening 108 of the negative pressure chamber 25, for example, in a non-contact manner or through a sliding contact. A sealing element 109, for example a sealing plate 109, may be provided in the region of the connecting tube piece 107 and / or the opening 108. The opening 111 of the connecting pipe piece 103, for example, the pipe piece opening 111, is arranged so as to overlap the opening 108 so that at least one overlapping portion is generated at every operating position of the carriage 103. The connecting pipe piece 107 is provided with a lower negative pressure P− with respect to the surroundings, not shown, via a suction line 99 that guides a fluid with a lower pressure with respect to the surroundings, for example the surroundings. For example, coupled to the suction side of a pump, turbine or ventilator. The P-connection of the movable negative pressure chamber 25 may alternatively be rigidly coupled or coupled to a flexible tube, so that the movement of the suction chamber is hardly obstructed ( Not shown).

  FIG. 18 schematically shows the position of the third variant carriage 103 on the basis of the relative positions of the cooperating guide elements 101; 102 for various driving situations and associated load conditions. ing. In the first relative position (a), the carriage 103 or the outlet-side diverting roller 81 is brought to a position closer to the inlet-side diverting roller 82, and this first relative position (a). Is, for example, occupied only when the belt tension is applied, that is, only the tension of the unloaded circulating travel means 05 is applied without the operation of the means 25 for increasing friction. When the substrate sheet 01 is transported using the negative pressure P− (means 25 is actuated), for example, further away from the diverting roller 82 on the inlet side based on the entrainment of the means 25 in the transport direction T. Position (b) is produced. Therefore, the resistance increased by the contact of the edge portion 13 is transmitted to the circulating travel means 05 through the frictional coupling type coupling, and from there, it is transmitted to the deflecting roller 81 which is elastically deformed by the increase in the tension of the circulating travel means 05. Then, the carriage 103 occupies a position (c) closer to the entrance-side diverting roller 82 again, for example. If no belt tension or another load is applied, then the carriage 103 is brought to an end position (d), for example farther from its inlet side.

  In the fourth variant of the second embodiment, which is not shown in itself, the exit-side diverting roller 81 is different from both first variants in that it is also not movable and can move linearly, It is supported so as to be linearly movable parallel to the transport direction T. In contrast to the third variant, the fourth variant is functionally different only in that the means 25 for increasing friction, for example the negative pressure chamber 25, are arranged in a fixed frame. The description relating to the spring element 104, possibly a stopper 96 provided in accordance with the second variant, and the spring-elastically supported diverting roller 84 in the guide section 87 running behind the drive device apply accordingly. Is done.

  In FIG. 19, as exemplified for the configuration of the negative pressure chamber 25, the negative pressure chamber 25 has at least one opening 91 on the side facing the substrate sheet 01 and / or the circulating travel means 05 to be conveyed. For example, one opening 91 having a large area or a plurality of openings 91 spaced apart from each other, for example, a suction opening 91 is provided. The negative pressure P− acting on the negative pressure chamber 25 through the opening 91 acts to attract the conveyed printing material sheet 01 to the circulating travel means 05. The one or more openings 91 may preferably be arranged immediately below the circulating travel means 05 which, for example, is configured as a perforated belt 05 in this configuration. In this case, for example, the one or more openings 91 configured in the form of slits may be arranged to cooperate directly with the holes 112 of the perforated belt 05 which normally covers most of the openings 91, resulting in holes The printed material sheet 01 is attracted to the belt with holes 05 through 112. The description of the function and connection of the negative pressure chamber 25 is that of the negative pressure chamber 25 in a frame-fixed configuration (that is, having no movable carriage 103, for example, having a rigidly connected or connectable connecting pipe piece 107). The present invention is applicable to both the configuration and the configuration having the movable carriage 103.
