This cleaning method uses a solvent to soften the ink remaining on the ink supply roller that applies ink to the plate surface, and then presses a cleaning cloth against the ink supply roller and moves it intermittently or continuously to clean the softened ink. The cleaning cloth is impregnated and retained in the solvent absorbing layer of the cloth, and then the cleaning cloth is discarded. Disposal methods include cutting the used cleaning cloth with a cutter when it reaches an appropriate length, or winding it up into a roll. In the case of a cleaning cloth whose solvent absorption layer contains an oil coagulant, the used cleaning cloth is heated with a heater, and the absorbed ink is solidified or gelatinized by cooling after heating, and then disposed of.

If you try to handle the product without facing the layer side toward the worker, you may touch surrounding objects and contaminate them. In addition, in roll-winding processing, the solvent absorption layer is handled facing the operator and surrounding objects, so care must be taken to avoid ink stains, which reduces work efficiency. .

る。[Operation] After softening the ink adhering to the ink supply roller with a solvent, a cleaning cloth is pressed against the ink supply roller,
Wipe off ink and cleaning waste from the roller surface. This wiping operation is performed by driving a winding roll to wind up the cleaning cloth continuously or intermittently. As shown in FIG. 1, the used cleaning cloth that has absorbed ink and cleaning waste is wound up in reverse so that its solvent absorbing layer is on the shaft side of the winding roll. That is, since the solvent absorbing layer is located inside the solvent impermeable layer and is not exposed on the roll surface, the take-up roll can be easily handled when replacing the roll. In addition, when using a cleaning cloth whose side edges are wrapped in a solvent-impermeable layer, the solvent-absorbing layer into which ink and cleaning waste permeates is the solvent-impermeable layer on the roll surface side and the solvent-impermeable layer inside the solvent-impermeable layer. It is encapsulated by a solvent-impermeable layer on the layer and side edges. Therefore, the ink and cleaning waste in the solvent absorbing layer are trapped inside and do not seep out from the take-up roll, making the take-up roll easier to handle.

成される。Next, the structure of the cleaning cloth will be explained. FIG. 2 shows an embodiment of the cleaning cloth, which is provided with a solvent absorption layer 7 that comes into contact with the ink supply roller 10 and wipes off the ink waste liquid on the roller surface, and is impermeable to a solvent that does not allow the ink waste liquid to pass through the solvent absorption layer 7. It is constructed by polymerizing layer 8. At the side edges of the cleaning cloth, cross sections of the solvent absorbing layer 7 and the solvent impermeable layer 8 are exposed. The solvent absorbing layer 7 is made of a material that has good absorbency for ink waste liquid, and is made of, for example, a nonwoven fabric having a thickness of 3 to 5 mm and made of polypropylene fiber as a base material. Further, the solvent impermeable layer 8 is formed of a plastic film such as polypropylene having a thickness of 10 to 30 microns, for example.

出しはない。According to the cleaning cloth of this embodiment, by appropriately selecting the material, thickness, etc. of the solvent absorption layer for the ink waste liquid to be wiped off, the ink waste liquid that has soaked into the solvent absorption layer is retained within the layer. Therefore, ink waste liquid does not seep out from the solvent absorbing layer exposed at the side end of the roll when it is wound on the take-up roll.

The cleaning cloth 4 includes a first solvent absorbing layer 11 formed of a material with good waste oil absorbency, for example, a relatively thin nonwoven fabric, and an ink for absorbing waste oil from the first solvent absorbing layer 11 and maintaining that state. A second solvent-absorbing layer 12 made of a material with good retention properties, such as a relatively thick non-woven fabric, is provided, and a solvent-impermeable layer 13 that prevents waste oil from seeping out is provided on the outside of the second solvent-absorbing layer.
It has a three-layer structure.

A rolled-up portion 8A or 13A is formed in which the edge of the solvent-absorbing layer 7 shown in FIG. 4a is wrapped by the solvent-impermeable layer 8, and the edges of the solvent-absorbing layers 11 and 12 shown in FIG. 4b are wrapped by the solvent-impermeable layer 13. It is provided.

ことができる。When the winding portion is provided in this manner, when the used cleaning cloth is wound up on the take-up roll, for example, in the solvent absorption layer 7 of the two-layered cleaning cloth, as shown in FIG. Since the entire body is covered with the impermeable layer 8 and completely isolated from the outside, there is no leakage or seepage from the sides of the roll in addition to the roll surface, allowing cleaner processing.

る。Next, the operation of the above embodiment will be explained. When the cleaning operation is started, the ink adhering to the ink supply roller is softened by a solvent, and then the pressing pad is moved forward to press the cleaning cloth against the ink supply roller to wipe off ink waste liquid on the roller surface. This wiping operation is performed by driving a winding roll to wind up the cleaning cloth continuously or intermittently. The used cleaning cloth that has absorbed the ink waste liquid is wound up in reverse so that its surface is on the shaft 3a side of the winding roll. That is, as shown in FIG. 1(b), the used cleaning cloth is wound up on a take-up roll with the solvent-impermeable layer facing outside. Therefore, the solvent absorption layer impregnated with the ink waste liquid is covered with the solvent impermeable layer and does not appear on the surface, making it easier to handle the winding roll.
