Description

Cylinder Cleaner

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cylinder cleaning apparatus for cleaning a cylinder surface such as a blanket cylinder, a pressure cylinder, an ink roller of an offset printing machine with a cleaning cloth, and more specifically, a cleaning cloth is formed in a roller shape, a half folded shape (folded in a zigzag), and the like. The present invention relates to a cylinder cleaning apparatus having a structure in which an outer circumference of a cleaning cloth supply manufactured in a shape or a container containing the cleaning cloth supply is placed.

In a cylinder cleaning apparatus for cleaning a cylinder surface such as a blanket cylinder of a conventional offset printing machine with a cleaning cloth, the cleaning cloth is made of iron before use in a cleaning fabric roll wound on a hollow paper core. It is common to insert a metal shaft such as a back and mount the metal shaft as a rotating shaft to a cleaning unit. 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 portion becomes arched due to the pulling force of the cleaning cloth winding-up means, so that the normal cleaning cloth is not supplied. There was also a risk of the rolls sticking out and 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 by a fastener, and attached it to a washing | cleaning apparatus by the fastener also took time.

In addition. Efficient and resource-saving scrubbing rolls have been proposed to reduce the amount of thick paper cores, namely core parts, to wrap more cleaning cloths. Since it is impossible, there is a problem in strength in the method of the conventional apparatus, and the countermeasure is desired.

It is an object of the present invention to provide a cylinder cleaning apparatus which makes the portion of the core very thin or does not use the core, and consequently improves the space efficiency (space element) of the cleaning cloth supply.

Still another object is that it can be mounted on a cleaning cloth roll having a different diameter of different cores, moreover, it is easy to install with less effort to attach the cleaning cloth roll to the cleaning unit, and it is not only a roll-shaped cleaning cloth as a cleaning cloth but also a semi-folded cleaning The present invention provides a cylinder cleaning device having a mounting means for cleaning cloth applicable to grapes.
