Definitions

  • the present invention relates to a cylinder cleaning device for cleaning a surface of a cylinder such as a blanket cylinder of an offset printing machine, an impression cylinder or an ink roller. More particularly, the invention relates to a cylinder cleaning device in which a cleaning fabric supply element is made in a roll form, or folded in a pleated form (or folded in zigzags), or a container holding the cleaning fabric supply element.
  • a cleaning fabric as used, is wrapped around a hollow core to form a cleaning fabric roll, into which a shaft made of metal is inserted.
  • This metal shaft in the cleaning unit as a rotary shaft.
  • This arrangement has been widely used.
  • a method of directly holding a core to make it a rotary shaft without using such metal shaft has been proposed in Japanese Patent Laid-Open No. 234659/1992 and in EP-A-0 479 403.
  • An object of the present invention is to provide a cylinder cleaning device which is enabled either by thinning a roll core extremely or by using no roll core to improve the space efficiency (or space factor) of a cleaning fabric supply element and to use the cleaning fabric supply element held by a container while being small-sized.
  • a cylinder cleaning device for cleaning an outer surface of a cylinder by pressing a cleaning fabric supplied from a cleaning fabric supply element against an outer surface of said cylinder, comprising: a frame; and a cleaning fabric supply element container supported on said frame; and a cleaning fabric take-up shaft attached to the frame for taking up used cleaning fabric, forming thereby a cleaning fabric take up roll, wherein the cleaning fabric take-up shaft is arranged within a range to interfere with the container when the diameter of the cleaning fabric take-up roll increases, and wherein the container includes a structure whose shape is physically changed in a direction of increasing diameter of the cleaning fabric take-up roll.
  • the cleaning fabric can be easily handled, i.e., attached and detached.
  • the device can be made compact by arranging the cleaning fabric take-up shaft within the range in which the cleaning fabric take-up roll interferes with the container. It is also possible to use cleaning fabric rolls or cleaning fabric supply elements of various shapes or core sizes. Moreover, the various cleaning fabric supply elements can be used merely by slightly remedying the various types of conventional cleaning device, which has already been installed.
  • the cleaning fabric supply element is held in a reluctantly deformable and rigid container (e.g., a cassette or cartridge) or a deformable container a film material (including a container packaged with the film material), and the container is supported as it is, so that the handling of the cleaning fabric supply element is improved.
  • a reluctantly deformable and rigid container e.g., a cassette or cartridge
  • a deformable container a film material including a container packaged with the film material
  • the cleaning fabric can be prevented from volatilizing or drying by the container to suppress the reduction in the performance of the cleaning fabric, so that it can be easily handled. This effect is enhanced by holding the cleaning fabric using a highly volatile detergent in the container.
  • the amount of detergent to be introduced into or applied to the cleaning fabric is so high that the detergent can be prevented from leaking out of even the cleaning fabric impregnated in a saturated state and can be confined in the container.
  • the cleaning fabric as supplied from the cleaning fabric supply element, can be partially drawn back to the cleaning fabric supply side and used again as a new one to improve the using efficiency of the cleaning fabric and to lower the cleaning cost and spare the resources.
  • the cleaning fabric When the cleaning fabric is pressed onto the cylinder surface, a dragging force in the rotational direction of the cylinder acts upon the cleaning fabric, and this force may draw out the cleaning fabric from the cleaning fabric supply element.
  • the cleaning fabric can be braked by the brake means to overcome the dragging force so that it can be prevented from being drawn out.
  • cleaning fabric tensioning means moreover, there can be achieved the following advantage. If the cleaning fabric is slack, a wrinkle is formed in the cylinder pressing portion so that the cleaning fabric may not be uniformly pressed onto the cylinder surface to cause an non-homogeneous cleaning operation. With the slackness, on the other hand, the slack portion may come into contact to blot the cylinder surface or may be taken up on the cylinder, when it is not in the cleaning operation. These drawbacks can be eliminated by tensioning the cleaning fabric by the tensioning means.
  • a cylinder cleaning device for cleaning the outer surface of a cylinder by pressing a cleaning fabric supplied from a cleaning fabric supply element against said outer surface of said cylinder, comprising: a frame; a receiving member attached to the frame for receiving the outer surface of the cleaning fabric supply element; a first guide member extending longitudinally of the receiving member; and a second guide member extending longitudinally of the receiving member and pairing the first guide member, wherein the first guide member and the second guide member define an S-shaped passage in-between for allowing the cleaning fabric to pass there through.
  • the cleaning fabric can be stably supplied by causing it to pass through the S-shaped passage, as defined by the two guide members, from the state, in which it is received by the cleaning fabric supply element, to apply the braking action thereto and by causing it to pass through a predetermined portion near the cleaning fabric supporting receiver.
  • the roll core or the diametrically reduced cleaning fabric roll is blocked, when intensively forced to come out from the cleaning fabric supporting receiver, from disengaging out by the S-shaped passage so that the roll core or the cleaning fabric roll can be accidentally wrapped by the cylinder to damage the cylinder.
  • the strength of the cleaning unit can be enhanced to support the cleaning fabric supporting receiver stably and reliably.
  • the braking action on the cleaning fabric can be increased by the two S-shaped passages while further enhancing the disengagement preventing effect.
  • the passage of the cleaning fabric can be widely opened by turning the arm.
  • the introduction of the cleaning fabric into the S-shaped passage is completed by letting off the cleaning fabric from the received cleaning fabric roll to the outside of the other guide member, by returning the turned guide member to thread the cleaning fabric into the clearance between the returned guide member and the other guide member, so that the threading work of the cleaning fabric can be facilitated.
  • One guide member is turned across the open portion of the cleaning fabric supporting receiver to be charged with the cleaning fabric roll, so that it is positioned at the position opposite to the non-turned other guide member across the cleaning fabric supporting receiver.
  • the cleaning fabric roll can be introduced without being hindered by the turned guide member into the cleaning fabric supporting receiver so that the charging work can be facilitated.
  • the charging operation can be performed with an excellent workability by turning the cleaning fabric supporting receiver as a whole without being disengaged from the cleaning unit thereby to open the inlet side of the cleaning fabric supply element widely.
  • the urging means for urging the guide member When there is provided the urging means for urging the guide member, an intense braking action can be applied to the cleaning fabric so that the cleaning fabric can be highly tensioned and reliably prevented from becoming slack.
  • this cover member can be opened to introduce the cleaning fabric supply element to be charged, without disengaging the cleaning fabric supporting receiver from the cleaning unit, so that the workability can be improved.
  • the cleaning fabric supply element can be introduced without disengaging the cleaning fabric supporting receiver from the cleaning unit.
  • the take-up shaft is arranged in the proximity to the movable member so that the cleaning unit can be small-sized.
  • the movable member When the movable member is hinged to the side of the cleaning fabric guide member, the movable member moves according to the change in the diameter of the cleaning fabric roll to move the cleaning fabric roll toward the cleaning fabric guide portion so that the direction to let off the cleaning fabric from the cleaning fabric roll is hardly changed with respect to the cleaning fabric guide portion thereby to stabilize the letting-off of the cleaning fabric.
  • the disengagement preventing means for blocking the core having the wrapped cleaning fabric and the diametrically reduced cleaning fabric roll from disengaging out the safety of the cleaning work of the cylinder can be enhanced to prevent the damage of the cylinder in advance thereby to enhance the reliability of the device.
  • a cleaning fabric receiving device for receiving a cleaning fabric supply element and for being mounted to a cylinder cleaning device, comprising: a mounting member including end plates and a spindle; a receiving member coupled to the mounting member for receiving the outer surface of the cleaning fabric supply element; a guide member extending longitudinally of said receiving member and define an S-shaped passage in-between for allowing the cleaning fabric to pass there through, and wherein the spindle of said mounting member is attached for use to the frame of said cylinder cleaning device.
  • the present invention can be applied as an adapter without any changing work to the existing device of the type using a cleaning fabric supply element.
  • the cleaning fabric supply element can have any form such as a rolled form or a folded pleated form (i.e., folded in zigzags). Cleaning fabric rolls with a round-formed roll core or a rod-formed roll core or without any roll core can also be used.
