Definitions

  • a cleaning device for a photo-electrostatic copying machine with a scraper in which a first device brings the scraper out of contact with the photoconductor drum when the copying machine is out of operation and a second device a cleaning roller out of contact with the Photoconductor drum swivels or the system pressure is reduced.
  • Liquid developer is supplied as a cleaning liquid to the section of the photoconductor drum that is located between the stripper and the squeezing roller.
  • the devices for actuating the stripper and the squeeze roller are coupled to one another in such a way that the stripper and the squeeze roller are brought into and out of contact with the photoconductor drum at the same time.
  • a cleaning device in such a way that the lever arrangement consisting of several levers is arranged near the one end face of the drum, that each of the levers carries ball bearings at its free end, that one of the levers with its the other end sits on a thru axle and the other lever on a sleeve that the thru axle with a first profile tube is connected that above the lever arrangement are provided rotating cams which are in pressure contact with the levers via the ball bearings, pivot them and thereby bring the cleaning elements into and out of contact with the peripheral surface of the drum and that between a splash guard and the one cleaning element a bar is arranged, which extends over the length of the drum and has a roof profile that slopes outwards from the center of the bar towards the two ends.
  • cams 16, 17, 18 are seated on a camshaft shaft, which have different shapes from one another and come into pressure contact with the ball bearings 28, 29, 30 stand.
  • the shape of the cams 16, 17, 18 is eccentric so that they pivot the levers during one revolution and thereby bring the cleaning elements attached to the levers into and out of contact with the peripheral surface of the drum 6.
  • the cams are rotated against each other on the cam shaft 35, so that they pivot the levers 20, 21, 22 with respect to each other and different distances, whereby the cleaning roller 2 and the stripper 3 separated and with different pressure on the peripheral surface of the drum 6 and stand out from this.
  • a drive gear 19 connects to the cam disk 16 and is connected via a gear chain (not shown) to a drive 23, which is only shown schematically in FIG. 1, since it is a drive of the copier known per se.
  • the ends of a second profile tube 13 rest on the inner sides of the side plates 42 and are connected to the side plates by means of screws, not specified.
  • the second profile tube 13 has a square shape and serves to stiffen the cleaning device, which can have a length of more than 1 m, for example.
  • the bearings 14 for the journals of the cleaning roller 2 are arranged at a distance from the slide bearings 40 for the thru axle 26.
  • FIG. 3a A view of the bar 1, from which the drop of the bar can be seen from the center towards the ends, is shown as a partial view in FIG. 3a.
  • the mode of operation of the cleaning device 10 is explained in more detail below with reference to FIGS. 3 to 5.
