Abstract
A cylinder cleaning apparatus for a printing press includes a cleaning web take-up roll, a constant amount feed mechanism, a unit throw-on/throw-off actuator and an actuator, and a plate and bolts. The cleaning web take-up roll takes up a cleaning web supplied from a cleaning web supply roll to clean a circumferential surface of a cylinder. The constant amount feed mechanism takes up a constant amount of the cleaning web on the take-up roll regardless of an amount of the cleaning web taken up by the take-up roll. The unit throw-on/throw-off actuator and the actuator drive to rotate the take-up roll in taking up the cleaning web. The plate and bolts adjust a pivot amount of the take-up roll on which the constant amount of the cleaning web is taken up by the constant amount feed mechanism.
Claims19
An apparatus for cleaning a printing press cylinder using a cleaning web, comprising:
- take-up roll for taking up the cleaning web to clean a circumferential surface of the cylinder;
- a constant amount feed mechanism for causing a constant amount of the cleaning web to be taken up on said take-up roll regardless of an amount of taken cleaning web on said take-up roll;
- driving means for driving to rotate said take-up roll in taking up the cleaning web including a take-up lever for transmitting a pivot force to said take-up roll in only a take-up direction of the cleaning web, the take-up lever being biased in a counter take-up direction of the cleaning web, said take-up lever having an actuation target member;
- and
- adjusting means for adjusting a pivot amount of said take-up roll to cause a change in the constant amount of the cleaning web being taken-up on said take-up roll.

- a take-up roll for taking up the cleaning web to clean a circumferential surface of the cylinder;
- a constant amount feed mechanism for taking up a constant amount of the cleaning web on said take-up roll regardless of an amount of taken cleaning web on said take-up roll;
- a take-up lever for transmitting a pivot force to said take-up roll in only a take-up direction of the cleaning web and being biased in a counter take-up direction of the cleaning web, said take-up lever having an actuation target member;
- an actuating member for engaging with the actuation target member of said take-up lever to pivot said take-up roll;
- adjusting means for adjusting an initial distance between the actuation target member of said take-up lever and said actuating member;
- a cleaning unit including said take-up roll, said take-up lever, and said constant amount feed mechanism, and supported by a printing press frame and being movable between a cleaning position to cause the cleaning web to come into contact with said circumferential surface of said cylinder and a retreat position to separate the cleaning web from said circumferential surface of said cylinder;
- and
- an actuator for swinging said cleaning unit from the retreat position to the cleaning position in taking up the cleaning web to actuate said actuating member with respect to said take-up lever, thereby pivoting said take-up roll.
