Definitions

  • the invention relates to sheet transfer cylinders of sheet-fed rotary printing machines with a device for register correction of the imprints by deforming the front sheet edge, wherein a bending device is attached to the sheet transfer cylinder, which bends the gripper bridge shaft and thereby deforms the sheet front edge in or against the cylinder rotation direction in the middle, while the position of the in and the middle gripper bridge shaft bearing movable against the direction of rotation of the cylinder is determined by a cam mechanism with a return spring (US-A-2577099).
  • the gripper bridges of the sheet transfer cylinders of the printing presses affected are provided with control devices, the common feature of which is to be seen by deforming the sheet leading edge in or against the sheet running direction or also perpendicularly to the registration of the printed image influence.
  • a device which is characterized in that the respective in the sheet guiding devices, i.e. in the system drum, in the printing cylinder or in the transfer drums between or after the printing units, consisting of the gripper support and the gripper shaft carrying the grippers, the gripper arrangement is divided into individual sections along the leading edge of the sheet, with the two ends of both the gripper shaft and also the gripper support-detecting slides are arranged, which are displaceable in or against or transverse to the direction of the sheet travel.
  • the respective in the sheet guiding devices i.e. in the system drum, in the printing cylinder or in the transfer drums between or after the printing units, consisting of the gripper support and the gripper shaft carrying the grippers
  • the gripper arrangement is divided into individual sections along the leading edge of the sheet, with the two ends of both the gripper shaft and also the gripper support-detecting slides are arranged, which are displaceable in or against or transverse to the direction of the sheet travel.
  • the gripper bridge is also divided into individual sections, with each gripper support bar being additionally adjustable in height for the gripper bridge sections provided.
  • DE-A-2052786 also previously known, describes a sheet feeder device for printing presses.
  • a transmission device is mounted on a support shaft, the carrier of the gripper pads of this transmission device executing an additional pivoting movement about a pivot point formed by a further shaft. This pivoting movement is used to push the individual grippers back against a stop bar before picking up the paper sheet from the feed table.
  • a deformation of the leading edge of the sheet is achieved in that the gripper bridge shaft is bent in the middle essentially in or against the paper running direction.
  • a bending device is attached to the sheet transfer cylinder.
  • the position of the middle gripper bridge shaft bearing and thus the deflection of the gripper bridge shaft is determined by a control cam attached in the front area of the sheet transfer cylinder with the associated roller and return spring.
  • a torsion shaft required for power transmission forms u. a. the cause of possible vibrations and inaccuracies in the transmission of motion.
  • the invention is based on the object of creating a device with a simple construction on a sheet transfer cylinder, with which certain dimensional changes of the sheet can be carried out by deforming the sheet leading edge.
  • the control should be direct and without the interposition of other, e.g. Vibrations and similar disturbances causing transmission elements act on the gripper device.
  • a gentle treatment of the leading edge of the sheet should also always be guaranteed.
  • the grippers are already known per se for feed cylinders which take the sheet from the feed table and pass it on to the impression cylinder to make the bridge pivotable relative to the feed cylinder in order to ensure that the gripper absolute speed is zero when taken over from the feed table.
  • This device also takes into account the fact that the dimensional change in the first printing unit is of crucial importance. Since a first printing process for the reverse side of the sheet can again be assumed in perfecting and reverse printing machines after turning, the device according to the invention also makes a decisive contribution to register correction of the prints there.
  • the grippers 1 of the feed cylinder 2 shown in FIG. 1 take over the paper sheet 3 to be printed from the feed table 4 and then transfer it to the printing cylinder 5.
  • the sheet 3 experiences an acceleration which makes it zero in terms of its absolute speed, which it takes on when it is taken over Feed table 4 has up to the cylinder peripheral speed when it is transferred to the printing cylinder 5.
  • the gripper bridge 6 is designed to be pivotable relative to the feed cylinder 2.
  • the swivel movement is controlled in such a way that the gripper bridge 6 performs an overstroke movement shortly before the sheet 3 is taken over and swings back into its starting position during the takeover and during the further transport of the sheet.
  • the swiveling-back speed of the gripper support 7 is equal to the negative cylinder peripheral speed, so that an absolute speed is equal to zero.
  • the gripper bridge 6 no longer pivots.
  • the front edge 8 of the sheet 8 is deformed after taking over from the feed table 4 until it is transferred to the printing cylinder 5 in or against the paper running direction in the middle, taking advantage of the pivoting movement of the gripper bridge 6.
  • the middle bearing 11 of the gripper bridge shaft 10 shown in FIG. 1 is loosely mounted about a pivot point 12 approximately in or against the direction of rotation of the cylinder, said pivot point 12 on a support arm 13 is arranged.
  • the latter is arranged in a rotationally fixed manner on the cylinder axis 14 and supports the entire bending device 15 for bending the gripper bridge shaft 10.
  • the position of the middle bearing 11 of the gripper bridge shaft 10 is determined by a control cam 16 which is rotatably mounted on the gripper bridge shaft 10 and during the pivoting movement thereof runs against a roller 17 which is in turn mounted on a bracket 18 of the support arm 13.
  • a return spring 19 ensures that the control cam 16 is constantly in contact with the roller 17 and presses the pull rod 21 and a bearing arm 22 against the roller 17 via a threaded piece 20 and a bearing arm 22.
  • the position of the return spring 19 is determined by its stop on an angle 23 screwed to the support arm 13.
  • Their pretensioning force is determined by a pretensioning nut 24 provided at the other end of the threaded piece 20.
  • An additional lock nut 25 djentderSich réelle,.
  • the control curve is for bracing the leading edge 8 of the bow or for bending the gripper bridge shaft 10 against the direction of rotation of the cylinder 16 provided with a recess 26 into which the roller 17 engages during the pivoting movement.
  • the spring force of the return spring 19 always ensures that the control cam 16 is constantly in contact with the roller 17 and thus causes the gripper bridge shaft 10 to deflect by pivoting its central bearing about the pivot point 12 in accordance with the spring force.
  • FIG. 2 illustrates the deformation of the leading edge 8 of the sheet achieved with a device according to FIG. 1.
  • the overstroke of the gripper bridge 6 is shown in FIG. 3 shortly before the sheet is taken over from the feed table 4.
  • FIG. 4 shows the position of the swiveling gripper bridge 6 during the sheet transfer
  • FIG. 5 shows the transfer to the printing cylinder.
  • the device according to FIG. 6 differs from that according to FIG. 1 in that the control curve 27 is provided with an elevation 28.
  • the tensioning of the leading edge 8 of the bow or the bending of the gripper bridge shaft 10 in the direction of rotation of the cylinder now takes place.
  • control curve 16 according to FIG. 1 is only rotated counterclockwise by approximately 45 ° and thereby the starting point is selected such that when the sheet is taken over from The feed table 4 engages the roller 17 in the recess 26 of the control curve 16, while it then interacts with the cylindrical part of the control curve 16 during the sheet transfer.
  • FIG. 8 shows the deformation of the leading edge 8 of the sheet obtained with the control cam or its arrangement according to FIGS. 6 and 7.
  • control cams 16 and 27 are rotatably and lockably mounted on the gripper bridge shaft 10.
  • the respective control cam 16 or 27 is rotated relative to the gripper bridge shaft 10 in such a way that the starting position changes. Since the pivoting angle of the gripper bridge 6 remains unchanged, it can thus be achieved that when the sheet 3 is transferred to the impression cylinder 5, the control curve 16 or 27 does not yet have the lowest point of the recess 26 or the highest point of the elevation 28 the role 17 cooperates.
  • the pliers grippers 33 grip the trailing edge of the paper sheet 3. From this point in time, this trailing edge of the sheet is referred to as such for the further prints to the leading edge of the sheet. A corresponding renaming applies to the previous leading edge of the sheet, which now becomes the trailing edge.
  • the gripper bridge 34 is pivoted relative to the turning cylinder 32 and transfers the sheet 3 thus turned to the printing cylinder 35 of the next printing unit.
  • the sheet 3 is now deformed in or against the paper running direction in the middle using the pivoting movement of the gripper bridge 34.
  • the basic structure of the bending device 37 corresponds to that of the embodiment according to FIG. 1.
  • the position of the return spring 19, which also acts as a compression spring, is fixed by its stop on an angle 23 screwed onto the somewhat differently designed support arm 39.
  • the other side of the return spring 19 presses with the interposition of a loosely arranged disc 40 on one arm of a pivot lever 41, which is mounted on a joint 53 of the support arm 39, and thus provides for the middle gripper bridge shaft bearing 11 articulated on the other arm of the pivot lever 41 for the constant concern of the control curve 38 on the role 17.
  • Die The return spring 19 is guided longitudinally via a guide rod 42. Its exact position is determined by a preload nut 24 provided at the other end thereof. An additional lock nut 25 is used for securing.
  • a bolt 43 attached to the guide rod 42 cooperates with a longitudinal groove 44 in the pivot lever 41.
  • another bearing pin 45 attached to the bearing arm 22 of the middle gripper bridge shaft bearing 11 interacts with a further longitudinal groove 46 in the other arm of the pivot lever 41.
  • control cam 38 still interacts with the roller 17 with its cylindrical curve section 48 for a corresponding time.
  • Fig. 10 shows the sheet transfer position on the printing cylinder 35 of the next printing unit.
  • the interaction between the recess 49, cam 38 and roller 17 in this position can also be seen in this FIG.
  • the gripper bridge shaft 50 carrying the pliers grippers 33 is composed of the shaft 51 and a tube 52 mounted thereon.
  • the invention is of course not limited to the embodiments shown in the drawings.
  • the transfer of the concept of the invention to the diverse design options of sheet transfer cylinders may also require slightly different bending devices to deform the leading edge of the sheet.
  • a solution by means of eccentric control is also conceivable. It would be z. B. not to loosely store the middle bearing of the hook bridge shaft of the feed cylinder. Instead, the gripper bridge shaft would have to be offset eccentrically in this area, so that the axis of the section of the gripper bridge shaft carrying the grippers has a certain eccentricity with respect to the central gripper bridge shaft bearing.
