Definitions

  • the invention relates to a method and a device for washing a blanket located on a blanket cylinder of a rotary printing press.
  • a washing device For washing a rubber blanket located on a blanket cylinder of a rotary printing press, a washing device is known (see Walenski, see below), in which a cloth soaked with a washing liquid is pressed against the rotating blanket cylinder. It is disadvantageous that the employee employed on the blanket cylinder, standing cloth pushes dirt and paint on the blanket. When passing through a channel under the cloth dirt and paint are pushed into the channel. As a result, more and more dirt and paint accumulate in the channel, so that the clamping channel has to be cleaned by the printer from time to time. Narrow clamping channels fill up quickly enough, so they need to be cleaned more often.
  • the object is achieved by a method according to claim 1 and a device according to claim 2. Thanks to the lifting of the cleaning element in a part of the turns of the blanket cylinder in a wash cycle less dirt and paint are pushed into the clamping channel, so that it does not need to be cleaned so often. This reduces the downtime of the rotary printing press.
  • Fig. 1 shows a blanket cylinder 1, on which a blanket 2 is clamped. The latter is clamped with its ends in a running in the axial direction of the blanket cylinder 1 clamping channel 3.
  • a washing device for washing the blanket 2 is arranged, which operates with a cloth 4.
  • the cloth 4 is guided by a cleaning cloth roll 10 to a dirty cloth roll 11. It can be pressed against the blanket cylinder 1 by means of a positioning device 7.
  • An encoder 8 which signals the position of the tensioning channel 3 is connected to a control unit 9, which is connected on the output side to the adjusting device 7.
  • the cloth 4 is pressed against the blanket cylinder 1 and thus on the blanket 2.
  • the blanket cylinder initially performs a few revolutions, for example, six revolutions, in which the latter is briefly lifted from the blanket cylinder 1 during passage of the tensioning channel 3 under the cloth 4.
  • the position or the passage of the clamping channel 3 under the cloth 4 signals the encoder 8 with a corresponding signal to the control unit 9.
  • This controls the adjusting device accordingly.
  • the adjusting device 7 moves, for example, a membrane or a plunger and brings the cloth 4 in the dashed line Andrückwolf. With a full line is in Fig. 1 the parked state of the cloth 4 is shown.
  • the wash cycle is then completed with a few turns, for example, one to two revolutions, in which the cloth is pressed continuously to the blanket cylinder 1. It is then so the area .des blanket 2 am Span 3 washed. Further detailed descriptions of the washing process, such as the supply of washing liquid or advancing the cloth 4, can be dispensed with, since this is familiar to the expert and, for example, in the book Walenski, The web offset printing, 1st edition 1995, sullenverlag, Fellbach, pages 340-345 , is described.
  • the encoder for the position of the clamping channel 3 may for example be arranged on the blanket cylinder 1 itself. But it can also be used a signal of the machine control.
  • Fig. 2 has arranged on the blanket cylinder 1 washing device as a cleaning element on a brush 5, which by means of a adjusting device 7.1 on the blanket 2 on or from this is swung.
  • the adjusting device 7.1 not shown for simplicity, in turn driven by a control unit 9, to which a likewise not shown position sensor 8 is connected for the clamping channel 3.
  • the first turns of the washing cycle are again carried out such that when passing through the clamping channel 3 under the brush 5 latter is briefly pivoted. Finally followed by one or a few turns of the blanket cylinder 1, in which the brush 5 is employed.
  • Fig. 3 has a washing device as a cleaning element, a doctor blade 6, the anschreib- with an adjusting device 7.2 to the blanket cylinder 1 and can be moved away from this.
  • the adjusting device 7.2 is analogous to the previous embodiments with a control unit 9, not shown in connection, to which a likewise not shown encoder for the position of the clamping channel 3 is connected.
  • a control unit 9 not shown in connection
  • a likewise not shown encoder for the position of the clamping channel 3 is connected.
  • For washing in turn, first a few turns of the blanket cylinder 1 are carried out, in which the doctor blade 6 is moved away when passing through the clamping channel 3. Finally, a few turns are performed in which the doctor blade 6 is employed on the blanket cylinder 1.
