Definitions

  • the invention relates to a device for adjusting parts on a cylinder of a rotary printing press according to the preamble of claims 1 and 7.
  • DE 35 04 435 A1 shows a device for adjusting paper stops attached to a register rail.
  • at least three adjusting screws are provided, each of which can be rotated by means of a servomotor.
  • a disadvantage of this device is that complex devices for transmitting electrical energy and control signals for controlling the servomotors arranged in the rotating cylinder are necessary.
  • the invention has for its object to provide a device for adjusting parts on a cylinder of a rotary printing press, in which a remote adjustment of these parts is possible even with a rotating cylinder, without the need to transmit electrical energy to the rotating cylinder.
  • the advantages that can be achieved with the invention are, in particular, that complex rotary transmitters, such as, for. B. wear-prone slip ring transmitters are not required for transmitting electrical energy.
  • feedback sensors can be omitted.
  • the display of the position of the parts, e.g. B. the front stops, can be done by simply counting actuating pulses outside the cylinder. It is also advantageous that no electrical components are used on the cylinder.
  • the device according to the invention is particularly suitable for use in areas where otherwise explosion-protected components must be used, for. B. in gravure printing machines.
  • the device according to the invention is shown in the drawing and is described in more detail below.
  • a first cylinder 1 which takes over the sheet, is provided with front marks 2 and grippers 4 mounted on a spindle 3.
  • sheets are created and aligned, which are processed in the sheet-fed rotary printing press.
  • At least two of these front marks 2 are arranged in their zero position parallel to an axis of rotation 6 of the cylinder 1 on its circumference.
  • a plurality of front marks 2 are fastened on a common register rail 7. This register rail 7 is slidably mounted in the tangential direction with respect to the cylinder 1.
  • threaded bolts 9 are slidably mounted at both ends and in the middle of the register rail 7 in a body 8 of the cylinder 1.
  • a gearwheel 12 which is provided with a central internal thread and is rotatable but otherwise stationary, is screwed on.
  • This gear wheel 12 is supported by an axial bearing 13 with an end face 14 on the body 8 of the cylinder 1 and thus forms a counter bearing for the force generated by compression springs 16 and acting on the register rail 7 in the tangential direction of the cylinder 1.
  • the Compression springs 16 are arranged between the register rail 7 and the body 8 of the cylinder 1.
  • a first pin 17 is fastened in the body 8 of the cylinder 1, and a second pin 18 is fastened in the gear 12, which together act as a stop for the gear 12 in the circumferential direction.
  • two drive pawls 19 are mounted so as to be linearly movable tangentially with respect to a pitch circle 21 of the gear 12.
  • These drive pawls 19 are pivotally mounted on a base support 22 with respect to the circumferential direction of the gear wheel 12 and are pressed into a basic position against the base support 22 by means of compression springs 23.
  • the base bracket 22 with the drive pawls 19 are attached in the body 8 of the cylinder 1, pressurizable working cylinder, for. B. pneumatic cylinders 24 moves.
  • the base supports 22 are provided with a bore 26 and the drive pawls 19 with an elongated hole 27, through which a piston rod 28 of the pneumatic cylinder 24 leads.
  • a threaded nut 29 is screwed onto the piston rod 28 to support the base support 22 and a second threaded nut 31 is arranged at the end of the piston rod 28 to support the compression spring 23.
  • the pneumatic cylinders 24 are arranged parallel and symmetrically with respect to an axis of symmetry 33 running through an axis of rotation 32 of the gear wheel 12. Between the pneumatic cylinders 24 is a tooth gap 34 of the Gear 12 acting, spring-loaded ball catch 36 attached to the body 8 of the cylinder 1.
  • the operation of the device according to the invention is as follows: Due to the oblique, convex or concave cut front edges of the sheets to be processed, the front marks 2 must be adjusted to the front edge.
  • the register rail 7 is shifted or bent obliquely by means of at least one device according to the invention.
  • a pneumatic cylinder 24 is optionally actuated for the tangential adjustment of the register rail 7. This moves the driving pawl 19 supported on the base support 22 in the tangential direction with respect to the pitch circle 21.
  • the driving pawl 19 engages a tooth 37 of the gear 12 and rotates the gear 12 by a corresponding angle of rotation.
  • the driving force acting on the gear 12 due to the drive pawl 19 is greater than the acting holding force of the ball catch 36 and the required adjusting force.
  • the ball catch 36 springs back during the adjustment movement and engages in a next tooth gap 34.
  • the pneumatic cylinder 24 is vented and performs a return movement of the base support 22.
  • the gear 12 is fixed by means of the ball catch 36.
  • the drive pawl 19 abuts a subsequent tooth 37 and carries out a pivoting movement against the compression spring.
  • the drive pawl 19 slides the tooth 37 over and then swings back again, so that the drive pawl 19 rests against the base support 22. This process can be repeated any number of times until the register rail 7 has reached the desired position.
  • the pivotable drive pawl 19 can, for example, also be designed as a leaf spring which is supported against the base support 22.
  • a pneumatic cylinder 24 carries out more strokes than the maximum adjustment path allows. As a result, the pin 18 of the gear 12 strikes against the pin 17 and is thus in a defined position. From this position, a control of the pneumatic cylinder 24, not shown, can approach each position of the threaded bolts 9 of the register rail 7 in discrete steps.
  • this device can also be used to adjust the height of the front marks (2) if they are appropriately supported.
  • This adjustment device is also suitable for adjusting other parts (e.g. plate clamping devices, register pins) on other cylinders (e.g. plate cylinders) of a rotary printing press instead of the front marks.
  • other parts e.g. plate clamping devices, register pins
  • other cylinders e.g. plate cylinders
  • the adjustment movement is carried out in discrete steps using a pulse-controlled working cylinder.
