Description

Cylinder Cleaner

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cylinder cleaning apparatus for cleaning cylinder surfaces such as bracket cylinders, pressure cylinders, ink rollers, and the like of an offset printing machine with a cleaning cloth. A cylinder cleaning device having a structure in which an outer circumference of a cleaning cloth supply body formed in a shape or a container containing the cleaning cloth supply body is mounted.

In a cylinder cleaning apparatus for cleaning a cylinder surface such as a bracket cylinder of a conventional offset printing machine with a cleaning cloth, the cleaning cloth is made of a metal shaft such as iron before use in a cleaning cloth roll wound on a thick paper core. It is common to insert the metal shaft into the cleaning unit by using the metal shaft as a rotating shaft. As a further improved method, a method in which a thick paper core is directly maintained as a rotating shaft without using such a metal shaft is also proposed, for example, in Japanese Patent Laid-Open No. 4-234659.

However, if the remaining amount of cleaning cloth decreases when the shaft is not used, the rigidity of the cleaning cloth roll decreases, and the center part becomes a bow shape by the pulling force of the cleaning cloth winding-up means, and the supply of the normal cleaning cloth does not come out, and the roll is protruded. There was a risk of breaking the press.

However, if the type of cleaning device is different, no cleaning cloth can be used because the outer periphery of the metal shaft suitable for the cleaning device is different or the size of the holding tool for directly holding the thick paper core is different. In addition, the work of attaching the cleaning cloth roll which puts a heavy shaft into a core, fixed a shaft and a core correctly in a fixture, and attached it to a washing | cleaning apparatus by a fastener was also required.

In addition, an efficient cleaning cloth for reducing the size of one part of the thick core, that is, the core part, that is, the core part, by reducing the amount of the cleaning cloth and reducing the size of the core, has been proposed. Since it cannot be used, there is a problem in strength in the method of the conventional apparatus, and the countermeasure is desired.

An object of the present invention is to provide a cylinder cleaning apparatus in which a portion of the core is made fine at one end or the core is not used, and as a result, the space efficiency (space element) of the cleaning cloth supply body is improved.

Still another object can be attached to cleaning cloth rolls having different diameters of different cores, moreover, it is easy to install with less effort to attach the cleaning cloth roll to the cleaning unit. The present invention provides a cylinder cleaning device having a mounting means for cleaning cloth applicable to grapes.
