Definitions

  • the present invention relates to a cylinder cleaning device for cleaning the surfaces of various cylinders and rolls in an offset printer, and in particular, to a cylinder cleaning device, wherein the structures of cleaning fabric and of a take-up shaft assembly, for winding a waste cleaning fabric, are corruptible in consonance with changes in a diameter of the shaft, configuration and a circumference of the shaft, that can facilitate performance of a disposal process for used cleaning fabric that is wound around a shaft.
  • the cleaning fabric is fed from a cleaning fabric supplying element that is formed into a roll, or that is reversibly folded, and is pressed against the outer circumference of the cylinder to clean it.
  • the used cleaning fabric is wound around a take-up shaft as the surface of the cylinder is cleaned.
  • belt shaped cleaning fabric 3 that is wound around a core, or that is fan-folded, is used.
  • the cleaning fabric 3 is wound around a take-up shaft 6 that has on its surface multiple tiny pointed protrusions 6a.
  • the take-up shaft assembly is proposed in, for example, Japanese Utility Model Laid-Open No. Hei 5-60843. A plurality of rows of raised and recessed portions are alternately formed around this type of take-up shaft.
  • a cylinder cleaning device for cleaning a circumferential surface of a cylinder by pressing a cleaning fabric passed between cleaning fabric supplying element for the cleaning fabric and cleaning fabric take-up shaft assembly for taking up the cleaning fabric against the circumferential surface of the cylinder, comprises:
  • the assembly has a mechanical structure for changing a diameter of the cleaning fabric take-up shaft assembly, a mechanical structure for changing a configuration of the cleaning fabric take-up shaft assembly, or a mechanical structure for changing a circumference of the cleaning fabric take-up shaft assembly.
  • the take-up shaft assembly Since provided for the take-up shaft assembly is an assembly for mechanically changing a condition at an area where the cleaning fabric take-up shaft assembly contacts the cleaning fabric that is wound around it, its diameter can be reduced after the cleaning fabric has been wound. As a result, the winding force with which the cleaning fabric is applied to the take-up shaft is extremely reduced. Therefore, the take-up shaft can be easily removed from the cleaning fabric roll.
  • the used cleaning fabric is disposed of as a roll, operating efficiency is improved, compared with a conventional case where the used fabric must be unrolled to be disposed of, and contamination of the periphery and of workers is reduced. In other words, the maintenance is improved.
  • the cleaning fabric take-up shaft is constituted by a plurality of divided shaft members, the structure for changing the diameter is simplified and manufacturing costs are reduced.
  • the diameter can be easily increased or reduced, and the increased diameter can be stably maintained.
  • a condition where a cleaning fabric roll contacts the outer periphery of the shaft member is changed by removing the bar member from the shaft member, so that the shaft member is easily removed from the cleaning fabric roll.
  • the condition where the fabric roll contacts the shaft member can be changed more drastically than can that where a bar member is removed from a single groove, and the removal of the shaft member becomes even easier.
  • the bar members engaged at one side end are released from the shaft member, and are brought near each other by the winding force exerted by the cleaning fabric roll. As a result, the circumference of the shaft is reduced and the contact condition between the shaft member and the fabric roll is changed, so that the removal of the shaft member is easy.
  • such a long shaft When a long shaft is used, accordingly, the length of a bar member is increased and its removal from a cleaning fabric roll becomes more difficult. It is preferable that such a long shaft have a structure such that an engagement member is provided at the middle portion of a groove to engage the ends of the bar members on one side, or a structure such that bar members are coupled together in the groove. With such an arrangement and such an engagement member, a short bar member can be employed. As a result, the removal of the bar member is facilitated and the operation can be easily implemented from either side of the shaft.
  • a cylinder cleaning device for cleaning a circumferential surface of a cylinder by pressing a cleaning fabric passed between cleaning fabric supplying element for the cleaning fabric and cleaning fabric take-up shaft assembly for taking up the cleaning fabric against the circumferential surface of the cylinder, comprises:
  • an assembly that easily engages the take-up shaft, and which has a certain strength relative to the rotational direction of the take-up shaft, is provided at a predetermined end portion, or at a location at which the cleaning fabric can be engaged, so that engaging the cleaning fabric with the take-up shaft is easily accomplished, the positioning is accurate, the attachment of the fabric around the take-up shaft can be precisely performed.
  • Reinforcement, or coating or impregnation with low friction material, or with a curing agent, is performed for the portion where the means of the cleaning fabric to be engaged is provided to prevent deformation of that portion, and engagement/disengagement can be stably performed.
  • the portion that contacts the outer periphery of the take-up shaft on the cleaning fabric side and/or the outer periphery of the take-up shaft are smoothed, and the used cleaning fabric can be removed from the take-up shaft and can be disposed of as a roll. Thus, the handling of the used cleaning fabric is improved.
  • the member to be engaged with which the used cleaning fabric is wound is removed from the take-up shaft, and from the outside is pushed toward the center to reduce the diameter of the take-up shaft, and make it possible to remove the member to be engaged.
  • cylinder cleaning fabric is wound into a roll or is fan-folded, and has means to be engaged, which engages engagement means on a take-up shaft that is installed in a cylinder cleaning device.
  • a cleaning fabric, or a connection member contiguous with the cleaning fabric has a smooth portion that contacts an outer surface of a take-up shaft, and a hole, a slit, a cut, or a cut-out strip is formed at or near the end of the fabric.
  • a cleaning fabric mounting element is provided on the cleaning fabric side.
  • the cleaning fabric mounting element is constituted by one or more bar members, or string members attached to a cleaning fabric, or to a member that is added to the cleaning fabric. Further, a cleaning fabric mounting element obtained by processing a cleaning element, or a member added to the cleaning fabric, is provided.
  • a cleaning fabric is easily wound around a take-up shaft by engaging the means to be engaged of the cleaning fabric with the above described engagement means, and a right angle can be stably maintained.

  • These components are supported by side plates 9 that are parts of a frame constituting the cleaning unit 2.
  • the cylinder pressing part supplies compressed air to an inflation member 7a that, when inflated, presses the cleaning fabric against the surface of the cylinder 1. Further, the cylinder pressing part releases air from the inflation member 7a to deflate it, as is indicated by a broken line 7b, and thus separate the cleaning fabric 3 from the surface of the cylinder 1.
  • the cleaning fabric supplying element 4 is used for a roll of the cleaning fabric 3, or for fan-folded cleaning fabric 3. Especially, a cleaning fabric roll having a tube core or a bar core, or one that has no core, can be used.
