圧を調整することができないので、充分な洗浄機能が期
待できないという問題点がある。However, such a conventional cleaning device has a problem in adjusting the contact pressure between the web and the peripheral surface of the blanket cylinder when the thickness of the printing paper is changed. That is, when the thickness of the printing paper is changed, the contact pressure of the web with respect to the blanket cylinder peripheral surface changes by moving the blanket cylinder according to the paper thickness, and it is necessary to adjust this contact pressure. The conventional cleaning device cannot adjust the contact pressure, so that a sufficient cleaning function cannot be expected.

It is an object of the present invention to provide a printing cylinder cleaning device for a printing press.

物が洗浄ウェブに転移して運び去られる。For example, when the printing paper is changed from thick paper to thin paper and, for example, a blanket cylinder as a printing cylinder moves in a direction away from the cleaning web, the pressing means is advanced to advance the supporting member pivotally supported on the swing base. And, since the guide member supported by the support member moves forward and the cleaning web slid against the cleaning surface against the guide member is pressed against the peripheral surface of the blanket cylinder and corresponds to thin paper ,
When the cleaning web is run in this state, foreign substances on the blanket cylinder peripheral surface are transferred to the cleaning web and carried away.

動にかかわらず一定になる。When the support member advances, one of a plurality of rollers supported by the support member comes into contact with the peripheral surface of the blanket cylinder, and then the other rollers come into contact with the peripheral surface of the blanket cylinder. Since the support member swings until it comes into contact, the right and left contact pressure between the peripheral surface of the blanket cylinder and the pressing member becomes constant regardless of the movement of the blanket cylinder peripheral surface due to the change in the paper thickness.

Pressing means for pressing against the peripheral surface of the roller;
Both ends of the printing cylinder / roller are attached to a member moved by the
Swingably supported so that it can be freely moved toward and away from the peripheral surface of the
And the supporting member on both sides of the swing center of the supporting member.
Multiple supported in contact with the peripheral surface of the printing cylinder / roller
And the washing provided on both ends of the support member.
A guide member for guiding the anti-cleaning surface of the web by sliding it
As a result, when the thickness of the printing paper is changed, when the support member is moved forward and backward by the pressing means, one of the plurality of rollers supported by the support member comes into contact with the peripheral surface of the blanket cylinder. Is because the support member swings until the other rollers come into contact with the peripheral surface of the blanket cylinder, so the right and left contact pressure between the peripheral surface of the blanket cylinder and the pressing member is changed by the paper thickness change. Irrespective of the pressure, the contact pressure of the cleaning web can be kept constant by a simple operation of moving the pressing means back and forth without using a tool, so that the operability and the cleaning function are improved. In addition, a constant contact pressure is always obtained without being affected by the assembly accuracy, and workability is improved.
