Definitions

  • the invention relates to a side and circumferential register setting device according to the preamble of patent claim 1.
  • DE-OS 27 20 313 shows a device in which the side register is set by axially displacing the transfer cylinder.
  • a roller which is rotatably attached to a pivot lever, engages in a link arranged on a cylinder journal end.
  • the swivel lever can be deflected by means of a worm gear via a handwheel.
  • the circumferential register is set by axially shifting a ring gear.
  • the ring gear is axially displaceable on the shaft journal end by means of a parallel key, but is non-rotatably mounted.
  • the gear rim has helical teeth on the outside, by means of which it engages in the helical teeth of a subsequent gear.
  • An axial displacement of the ring gear takes place by pivoting a roller which is in engagement with a link attached to the ring gear.
  • the roller is rotatably attached to a lever which can be pivoted by means of a handwheel and a worm gear.
  • the axial displacement of the ring gear caused by the helical toothing, results in a rotation of the ring gear and, by means of a feather key, a circumferential rotation (adjustment) of the cylinder.
  • the invention has for its object to provide a side and circumferential register adjustment device for a register drum of a hybrid machine consisting of offset and gravure printing unit, which can be finely and quickly adjusted, a gear provided for driving the register drum being in gear connection only with another gear should.
  • the register setting device can be regulated very finely, so that it can also be used to the full satisfaction in securities machine construction, in which high accuracy is important.
  • this is provided with an automatic control so that each sheet is individually measured during machine operation and is automatically corrected in lateral and circumferential position if there is a deviation from a desired position.
  • a register drum 4 for setting a side and circumferential register of a sheet 5 is arranged in a roller train 1 between two transfer drums 2, 3.
  • the first transfer drum 2 is a turning drum 6 and this a storage drum 7 upstream.
  • a printing cylinder 8 is arranged behind the second sheet transfer drum 3.
  • all drums and cylinders 2, 3, 6, 7, 8 are mounted directly in side frames 9, 11 of the rotary printing press.
  • the register drum 4 is u. a. from a coaxial shaft, the inner shaft 12 of which is firmly connected by means of its left end 13 to a left lever 14 and by means of its right end 16 to a right lever 17.
  • the levers 14, 17 are each pivotably mounted on bolts 21, 22, each of which is firmly fitted into the side frames 9, 11, and are separated from the side frames 9, 11 by spacers 23, 24.
  • the levers 14, 17 have a common axis of rotation 26 which is at a distance e an axis of rotation 27 of an outer shaft 28 is arranged.
  • the outer shaft 28 of the coaxial shaft 12, 28 is rotatably and axially displaceably mounted on the inner shaft 12 by means of needle bearings 29.
  • the right lever 17 is hinged to a shift rod 34 and the left lever 14 to a shift rod 33.
  • the shift rods 33, 34 are aligned parallel to each other and each via a coupling 36; 37 connected to a synchronization shaft 38 which is pivotably mounted in bearing blocks 40, 42 which are fixed on the side frame.
  • the couplers 36, 37 are each fixed to the synchronization shaft 38 and articulated with a first end 39; 41 of the shift rods 33; 34 connected.
  • the articulated connection between the coupling 36; 37 and the shift rod 33; 34 is in each case by a bolt 43; 44 produced by means of a tension spring 46; 47 for applying a restoring force is connected to a frame-fixed pin 48, 49.
  • the shift rod 34 has a rotatably mounted control roller 52 which is in contact with an axially aligned contour 53 of an adjustable control cam 54.
  • the control cam 54 is fixedly connected to a first end 56 of a control shaft 57.
  • the control shaft 57 is rotatably mounted in a bearing block 58 fastened to the side frame 11.
  • a second end 59 is positively coupled to a drive shaft 61 of a servomotor 62.
  • a pulse generator 66 connected to the output shaft 61 is connected to determine an angular position of the output shaft 61 and the control shaft 57.
  • a bearing block 81 is fastened to a carrier 74 and carries a rotatably mounted control roller 82.
  • the control roller 82 is in contact with an annular end face 83 of a vertically arranged control disc 84 which can be pivoted towards and away from the outside 79 of the register drum 4.
  • the control disc 84 is pivotably mounted on its upper part 86 about a pin 87 fixed to the frame and has a rotatably mounted control roller 89 on a lower part 88.
  • the control roller 89 is in contact with an axially aligned contour 91 of a control disk 92 and rolls on it.
  • the control disk 92 is fastened to one end 53 of a control shaft 94 which is rotatably mounted in the side wall 9.
  • the control shaft 94 is driven by a servomotor 96 attached to the side wall 9.
  • a plurality of compression springs 98 are used to apply a restoring force for the slide 97 deflected by the control disks 84, 92 and consisting of the outer shaft 28, gear 77 and carriers 74 provided, which are supported horizontally on the lever 17 and act on an axial bearing 99, which is also axially supported on the outer shaft 28.
  • the two servomotors 62 and 96 are connected via electrical lines (not shown) to a computer unit 101, from which they receive their positioning commands.
  • the computer unit 101 is connected to a reading device 103 via an electrical line 102. As shown in FIG. 1, the reading device 103 is arranged at a distance from the transfer drum 2 and is used to determine the position of a sheet 5 removed from the turning drum 6. A signal characterizing the position of the sheet 5 is transmitted to the computer unit 101 and with corresponding Setpoints for the lateral or circumferential position compared.
  • the computer unit 101 receives a signal from the pulse generator 66 which indicates the position of the control curve 54 and from a pulse generator (not shown) which indicates the position of the control curve 92.
  • the computer unit 101 calculates manipulated variables from these input signals and transmits them together with an evaluation circuit, not shown, as actuating commands to the actuators 62, 96.
  • the circumferential register is set as follows. Depending on the circumferential position of the sheet 5, the servomotor 62 rotates on the transfer drum 2 to the right or to the left, as a result of which the control cam 54 is also pivoted accordingly. Due to the contour 53 of the control cam 54, the shift rod 34 is against the force by means of the control roller 52 the tension springs 46, 47 shifted. As a result, the lever 17 articulated on the shift rod 34 is pivoted about the axis of rotation 26 of the pin 22. The lever 14 is correspondingly pivoted about the pin 21 via the coupling 36, 37 and the synchronization shaft. Here, the axis of rotation 27 of the inner shaft 16 moves on a circular path around the axis of rotation 26 of the bolts 21, 22.
  • the circular movement can be regarded as a linear displacement of the inner shaft 16.
  • the gear wheel 77, 78 Through the engagement of the gear wheels 77, 78, the gear wheel 77 and thus the slide 97 are pivoted about the tooth engagement point A of the gear wheels 77, 78, which at the same time characterizes the transfer point A between transfer drum 2 and register drum 4.
  • the transfer point A is constant and does not change its position. Since the transfer drum 3 is not in meshing engagement with the register drum 4, this is not rotated and there is a relative movement of a transfer point B between the grippers 104 of the register drum 4 and the grippers 106 of the transfer drum 3. The position of the transfer point B can be changed.
  • the grippers 104, 106 are designed such that they can grip and hold the sheet 5 in register over a sufficiently large area (approx. 3 mm).
  • a shift of the shift rod 34 z. B. in the direction of the arrow to the left has a pivoting of the register drum 4 clockwise and thus a shift of the transfer point B to the left, or as seen in the sheet transport direction to the front.
  • the servomotor 96 rotates, depending on the position of the sheet 5 on the transfer drum 2, clockwise or counterclockwise, whereby the control cam 92 is pivoted accordingly. Due to the contour 91 of the control cam 92, the control disk 84 is pivoted about the bolt 84 by means of the control roller 89, so that the control roller 82 axially moves the slide 97 with or against the restoring force of the compression springs 98 when rolling on the end face 83 of the control disk 84.
