Definitions

  • the invention relates to a device with a register pin arranged axially adjustable in a cylinder channel of a plate cylinder of a rotary printing press according to the preamble of claim 1.
  • stop piece according to DE-OS 20 45 953 it is a disadvantage of the stop piece according to DE-OS 20 45 953 that this only serves as a one-sided stop. With this measure, a pressure plate is only secured against lateral displacement in one direction. Necessary lateral fixation on both sides is not possible. It is also not possible to use the stop piece as a register pin, since the stop piece designed as a clamping sleeve changes its outer shape when it is clamped, as a result of which a dimension fixed before fixing is changed again when fixing.
  • US-A-38 99 972 shows a generic device with an adjustable register pin arranged in a cylinder channel of a plate cylinder of a rotary printing press.
  • the register pin is axially adjustable and consists of a register part and a fastening part.
  • the register part is for receiving a slit of a printing plate used for registration.
  • the fastening part faces axially aligned slots for attaching the register pin in axially extending recesses of the plate cylinder.
  • the invention has for its object to provide a device by means of the provided register pins on the plate cylinder of a rotary printing press can be individually axially adjusted and fixed.
  • each printing plate can be individually laterally aligned, for which purpose it is not necessary to move the entire printing plate device.
  • the device according to the invention can be used both on plate cylinders with bearer rings and on plate cylinders without bearer rings.
  • the device is structurally simple, inexpensive to manufacture and easy to use.
  • the register pin can be adjusted and fixed with a single tool.
  • FIG. 1 shows a conventional cylinder channel 1 of a plate cylinder 2 of a rotary printing press.
  • an insert bar 3 is arranged, each carrying a reversible device 4, 6 for fixing and tensioning a pressure plate 7.
  • the insert bar 3 is releasably attached to the plate cylinder 2.
  • one or more printing plates 7 can be arranged next to one another on an insert bar 3 on the plate cylinder 2.
  • a recess 9 in the form of a groove in the insert strip 3 is provided in the middle of the pressure plate 7 provided.
  • a register pin 11 is axially displaceable.
  • the register pin 11 consists of a fastening part 12 and a register part 13 which is firmly connected thereto.
  • the fastening part 12 has a first end 16 with an elongated hole 17 and a second end 18 also with an elongated hole 19 and a further continuous elongated hole 21.
  • the elongated holes 17, 19 are used to fasten the register pin 11 and are arranged in the axial direction of the plate cylinder 2.
  • the elongated hole 21 is used for the axial adjustment of the register pin 11 in the recess 9 of the insert strip 3 and is offset by 90 ° to the elongated holes 17, 19 in the circumferential direction of the plate cylinder 2.
  • the elongated holes 17, 19 each have a shoulder 22; 23 on which the head of a fastener 24, 26, z. B. a mounting screw 24, 26 supports. Below the slots 17, 19 is in alignment with them each lying a threaded bore 27; 28 is provided in the insert strip 3, in each of which a thread of the fastening screws 24, 26 engages.
  • a bore 29 is provided in the insert bar 3, arranged in alignment therewith.
  • an eccentric bolt 31 is rotatably mounted, which has an adjusting means 33, e. B. has a pin 33.
  • the pin 33 engages in the elongated hole 21.
  • the pin 33 has a hexagon hole 34 accessible from above and can be actuated with the same tool as the fastening screws 24, 26.
  • the fastening screws 24, 26 are first loosened, then the eccentric pin 31 is pivoted via the hexagon hole 34.
  • the pin 33 engages on a flank of the elongated hole 21 and, depending on the direction of rotation, axially presses the register pin 11 into the desired position in which the register pin 11 is fastened to the base 14 of the insert strip 3 by means of the fastening screws 24, 26.
  • the pin 33 can have a marking 36 and the fastening part 12 can have a scale 37. It is of course also possible to introduce a gauge between a reference side 38 of a stop piece 39 and the fastening part 12 of the register pin 11.
  • the stop piece 39 is fastened in the recess 9 by means of a taper pin 40 and a fastening screw 48 on the insert strip 3.
  • the register part 13 of the register pin 11 has a T-shape in the section according to FIG. 1, in which the corners formed between the horizontal upper part 41 and the vertical lower part 42 are rounded to suit the devices 4, 6 for fixing and tensioning.
  • a right end 43 of the register part 13 shown in FIG. 1 protrudes into an intended slot 44 (register slot 44) serving for registration in the leading end of the pressure plate 7.
  • a left end 46 of the register part 13 protrudes into an intended slot 47 (register slot 47) in the trailing end of the pressure plate 7 (FIG. 3).
