6 and the pad 17 for surface pressing can be applied to the pressing surface with uniform pressure along the longitudinal direction of the impression cylinder, and therefore the surfaces of the two impression cylinders can be uniformly cleaned, and the mutual position of the cleaning cloth with respect to the impression cylinder can be adjusted arbitrarily. Since it can be controlled by an air cylinder, in order to separate the cleaning cloth 4 from the claw 3 without installing the claw relief cam 14, the claw position is sensed by an encoder signal from the rotation of the impression cylinder, and the air cylinder, that is, the impression cylinder is cleaned. It is possible to control the cloth position, and since the cleaning unit 20 can be slid and fixed on the cleaning unit holding rail 21 provided along the longitudinal direction of the impression cylinder, it is possible to repair and repair the cleaning unit. Replacement is also easy. In addition, the cleaning liquid application nozzle installed on the top of the impression cylinder can apply multiple cleaning liquids separately, so it can remove ink stains that can only be removed with solvents, rubber stains, paper powder stains, etc. that can only be removed with water. It can be completely cleaned. [Example] An example according to the present invention will be explained according to the drawings. FIG. 1 is a side sectional view of the cleaning device, FIG. 2 is a perspective view of the cleaning device, and FIG. 3 is a side view showing the overall configuration of the printing device. The cleaning device is installed diagonally below the impression cylinder where it is least obstructive, and uses a magazine roll 5 with a spring brake for the cleaning cloth 4 that cleans the impression cylinder 1, and a sidewalk winding servo motor 6a to remove the cleaning cloth 4. A take-up roll 6 that winds up while moving it like a sidewalk, a guide roll 13, a guide plate l4, and a guide that guide the cleaning cloth 4 between the magazine roll 5 and the take-up roll 6 so that it faces the impression cylinder 1. Roll 15 and
On the back side of the cleaning cloth 4 facing the impression cylinder 1 between the guide plate 14 and the guide roll 15, the line pressure welding blade l6, the surface pressure pad 17, and a plurality of parallel presses for pressing these against the impression cylinder side are arranged. A cleaning unit 20 comprising an air cylinder l8 attached to a frame l9 is attached to a rail 2l provided near the impression cylinder 1 in parallel thereto, and a rail guide 19 attached to the frame.
It is constructed by attaching it slidably and removably by means of a. In this embodiment, a constant tension is always applied to the cleaning cloth by combining a magazine roll 5 with a spring brake and a servo motor, and by increasing the voltage applied to the servo motor only when winding up the cloth, the required amount is increased. Rolling up the cloth. Therefore, it is impossible for the cloth to interfere with the loosened claw. A processed L-shaped aluminum material is used as the line pressure welding blade l6. Hard chrome plating is applied to increase durability. Further, the surface pressure pad l7 is fixed to the C-shaped aluminum chamber 17a with an adhesive, and the L of the line pressure-welding blade l6 is fixed to the C-shaped aluminum chamber 17a together with the C-shaped chamber 17a.
The line pressure welding blade 16 and the surface pressure pad l7 are integrally attached to the horizontal part of the letter shape, and a U-shaped groove guide is formed by a plurality of pressure air cylinders l8 arranged in parallel. 22, the cleaning cloth 4 is simultaneously applied to the impression cylinder 1 by a line pressure bonding blade 16, and by a surface pressure pad 17 for surface pressure bonding. In addition, in order to simultaneously and uniformly press the cleaning cloth onto the impression cylinder surface using the blade and pad, the pad must have a sponge hardness of 5.
~ lO'' softness is required, and the material is solvent resistant and water resistant (P, P, P.E, Enbi, etc.)

きる。Furthermore, in order to prevent unnecessary liquid from entering the impression cylinder notch shown by reference numeral 1a in FIG.
c) In order to apply the solution evenly, the solution is introduced from both ends of one cleaning solution supply pipe l1, and the solution is ejected after the claw passes through the nozzle based on the signal from the encoder. It is. In addition, once the proper amount of cleaning liquid is stored in the piping tube, it is all pushed out using air, so by switching between supplying two or more types of cleaning liquid, it is possible to apply the liquid with a nozzle installed in one pipe. ．． In addition, each unit has a precision filter (
Ease of maintenance has also been taken into account by installing a mesh (101~100μm mesh) to prevent clogging of the nozzle discharge hole. In this example, two types of cleaning liquids were applied using nozzles provided on one pipe, but the types of cleaning liquids may be increased depending on the type of dirt, or a dedicated nozzle may be provided for each cleaning liquid. In addition, in order to prevent the cleaning cloth 4 from coming into contact with the impression cylinder 1 during printing, the cleaning unit 20 is separated from the impression cylinder 1 by an air cylinder l8, but the gap between the impression cylinder and the cleaning cloth is 1.
It is about 0m. Moreover, in case of malfunctions such as sudden air leaks, a spring is incorporated as a safety mechanism to separate the blade and pad from the impression cylinder, and in addition, a proximity sensor detects the movement of the pressure welding part. [Effects of the Invention] According to the present invention, the pressure JIF! A pressing air cylinder l8 for pressing the line pressure welding blade l6 and the surface pressure pad l7 toward the impression cylinder side is arranged in parallel in the longitudinal direction on the back side of the cleaning cloth 4 facing the cleaning cloth 1. 17 can be applied to the impression cylinder surface with uniform pressure in the longitudinal direction of the impression cylinder, and in addition to the linear pressure applied to the impression cylinder by the cleaning cloth, surface pressure is applied by the pad, so that cleaning can be carried out uniformly and efficiently. This enables uniform cleaning from the nail edge to the torso, which was impossible with the conventional method of pressing the cleaning cloth with a pad.In addition, by combining the blade and pad, it is possible to clean evenly with the weight of the torso. Compared to the method of pressing the cleaning cloth or the method of pressing the cleaning cloth with only a pad, cleaning time can be shortened. Moreover, the relative position of the cleaning cloth relative to the pressure can be controlled arbitrarily using compressed air.
Not only is it possible to control the cleaning cloth 4 to be separated from the pawl 3 without providing the pawl relief cam l4, but the cleaning unit 2o also has a cleaning unit holding rail 21 provided along the longitudinal direction of the impression cylinder. Since it can be slid and fixed, the cleaning unit can be easily repaired or replaced.

Can be done. Therefore, cleaning of the impression cylinder can be easily automated, saving labor and improving productivity. Although it has been practically impossible to attach a cleaning device to the side, etc., the present invention makes it possible to do so easily.
