Definitions

  • the invention relates to a device and a method for compensating slip of a printing forme sleeve on the forme cylinder of a printing unit.
  • DE 35 43 704 C2 shows a printing sleeve, which is held by means of a shrink fit on the forme cylinder.
  • a frictional connection there is a risk that the printing forme sleeve rotates in the circumferential direction when the shrinkage fit is not sufficiently strong.
  • a compression molding sleeve is provided on its inner wall with a guide element running in the direction of the longitudinal axis of the sleeve, for example a web, which projects into a groove of the forme cylinder in the assembled state of the sleeve.
  • a guide element running in the direction of the longitudinal axis of the sleeve, for example a web, which projects into a groove of the forme cylinder in the assembled state of the sleeve.
  • an embossing machine with which an already printed in a separate printing machine web can be provided with a specific pattern, i. to an existing print, the application of an embossing in a certain orientation.
  • This embossing machine requires only one on both sides of the already printed web arranged embossing rollers, so that the use of nested printing units for applying multi-color printing on a printing substrate problems occurring due to the shift in the printing units used printing sleeve can not occur.
  • the object is achieved with the features of the independent claims. Thanks to the single drive of a printing unit, a twisting compression sleeve together with the forme cylinder can be rotated back into a desired position without the need for a separate adjusting device, ie an additional motor.
  • a separate adjusting device ie an additional motor.
  • the way is open to mount compression sleeves on form cylinders without the risk of waste or loss of quality in a slipping of the sleeves form.
  • the printing form sleeves are inexpensive to create.
  • the invention will be explained in more detail below using an exemplary embodiment.
  • the single drawing shows schematically two printing units with a device for compensation of slip of a printing sleeve.
  • the figure shows two printing units 1,2 a web-fed rotary printing press.
  • Each printing unit 1, 2 contains a form 3, 4, transfer 5, 6 and impression cylinder 7, 8. These printing cylinder 3 to 8 are stored on one side in one or both sides in two side walls, not shown.
  • Each form cylinder 3, 4 is driven by its own motor (electric motor) 9, 10, wherein in the embodiment of the drive is indirectly via the transfer cylinder 5, 6.
  • the motors 9, 10 drive the transfer cylinders 5, 6, and of the latter, the drive of the forme cylinder 3, 4 by means of spur gears 11 to 14 on the journal of these cylinders.
  • motors could drive the forme cylinders 3, 4, and of these, the transfer cylinders 5, 6 are driven via spur gears.
  • each form and transfer cylinders 3 to 6 may be equipped with its own engine.
  • the impression cylinders 7, 8 are each driven by their own motor 15, 16.
  • the pressure cylinders 7, 8 can also be in drive connection with the transmission cylinders 5, 6 by means of spur gears.
  • the form cylinder 3 of the printing unit 1 carries a printing sleeve 17, which is fixed non-positively on this. Possibilities for the change of such a press-fit positioned pressure sleeve are shown in the aforementioned DE 35 43 704 C2.
  • the transfer cylinder 5 has a rubber blanket sleeve 18. Analogous to the printing unit 1, the forme cylinder 4 carries a reference compression sleeve 19 and the transfer cylinder 6 a blanket sleeve 20th
  • the transfer and impression cylinders 5, 7 and 6, 8 each of a printing unit 1, 2 are for printing a passage 21 passed between them each adjustable against each other.
  • the printing unit 1 prints a first web point 22 and the printing unit 2 a second web point 23 on the web 21.
  • the first web point 22 is scanned by a first sensor 24 and the second web point 23 by a second sensor 25.
  • Both sensors 24, 25 are connected to a comparison device 26, which is on the output side via a computer-motor control 27 with the motor 9 of the printing unit 1 in connection.
  • the first web point 22 is the impression of a first molding point 22.1 on the printing plate sleeve 17.
  • the second web point 23 is the impression of a second molding point 23.1 on the reference pressure sleeve 19 of the forme cylinder 4.
  • the first web point 22 is thus a first reference point for the position of the printing sleeve 17th in the circumferential direction of the forme cylinder 3. This position is to be in fixed relation to the position of the reference compression sleeve 19, which is represented by the second web point 23 as a second reference point.
  • the sensors 24, 25 scanning the track points 22 and 23 indicate with signals the passing of the first and second track points 22, 23 on the respective sensor 24, 25. In the comparison device 26, the signals are evaluated.
  • a point on the printing forme sleeve 17 itself can also serve, for example the first molding point 22.
  • the sensor 24 is to be directed to the forme cylinder 3, as indicated by dashed lines in the figure.
  • the evaluation in the comparison device 26 is carried out analogously to the evaluation when scanning the first path point 22, and at a detected Position deviation of the pressure sleeve 17, the motor 9 is readjusted accordingly.
  • a second reference point for the position of the reference pressure sleeve 19 can also be a point on this itself be used, for example, the second shape point 23.1.
  • the sensor 25 is to be directed to the form of printing sleeve 19 carrying the form cylinder 4.
  • the evaluation is carried out analogously to the evaluation when scanning the second path point 23.
  • a color register mark or a cut register mark can advantageously be used which is scanned on the web as the second web point 23 or on the printing form as the second mold point 23.1 with the sensor 25.
  • the so-called stand color is advantageously used as a color register mark, with respect to which the other colors are placed in the register.
  • the second reference point 23, 23.1 has a fixed relation to the cut register.
  • the first track point 22 and the second track point 23 ' can be scanned together by a sensor, for example the sensor 24, wherein the second track point 23' is adjacent to the first track point 24, in the embodiment before the second track point 23 printed point.
  • the printing units 1, 2 of the embodiment work according to an indirect printing method, for example in offset printing.
  • the device is also applicable to other indirect and direct printing methods.
  • each of the printing cylinder 15, 16 may be replaced by a printing unit containing a form and a transfer cylinder.
  • the device for slip compensation can be used both in the upper and in the lower printing unit.
