Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cleaning device for automatically removing foreign matter adhering to the surface of a rubber roller during the manufacturing process thereof.

[Conventional technology]

Rubber rollers used in printers of copiers and office automation equipment
Although it is required to finish the surface extremely precisely, foreign matter such as fine rubber scraps and dust adheres to the surface of the rubber roller during the manufacturing process.

Therefore, it is necessary to completely remove these foreign substances adhering to the surface of the rubber roller without damaging it in the finishing process.

However, conventionally, there is no device that automatically removes foreign matter adhering to the surface of the rubber roller, and an operator wipes the surface of the rubber roller one by one using dust-free paper containing isopropyl alcohol or the like.

[Problems to be solved by the device]

In view of the above conventional circumstances, the present invention aims to provide a rubber roller surface cleaning device that can automatically remove foreign matter adhering to the surface of a rubber roller without damaging it, and can contribute to improved productivity and cost reduction of the rubber roller. And

[Means for Solving the Problems]

In order to achieve the above object, a cleaning device for a rubber roller surface according to the present invention rotatably supports a backing plate fixed to a base and having a smooth surface, and a central axis of a rubber roller facing the backing plate surface at both ends. The roller gripper, a long adhesive tape supported between the rubber roller supported by the roller gripper and the receiving plate with the adhesive surface facing the rubber roller, and the roller gripper that receives the roller gripper in a direction perpendicular to the central axis of the rubber roller. And a roller moving device for moving along the plate surface.

In addition, instead of providing a roller moving device, a tape moving device that moves the adhesive tape along the receiving plate surface in a direction in which the rubber roller supported by the roller gripping portion can rotate while contacting the adhesive tape is provided. You can also

〔Example〕

A specific example of the cleaning device for the rubber roller surface of the present invention will be described with reference to FIGS.

Fix the base 2 to the upper end of the pillar 1 standing on the bed A,
A receiving plate 3 is horizontally fixed on a base 2 with a smooth surface 3a facing upward. Above the receiving plate 3, two horizontally extending guide rails 5 are fixed to the side wall 4 at both ends, and a base plate 6 suspended at both ends by the two guide rails 5 is formed as a guide rail 5.
It is supported so that it can move along. A support plate 7 is horizontally provided below the base plate 6 so that the support plate 7 can be moved vertically along a guide rod 7a by a roller contact / separation drive device including an air cylinder 11 fixed to the base plate 6. I'm running.

In addition, both sides of the support plate 7 in the width direction, that is, the two guide rails 5
On both sides in the direction orthogonal to the (moving direction), there are provided roller gripping portions made up of chucks 10 that rotatably support the central shaft 9 of the rubber roller 8 at both ends. It is designed to open and close. Further, the supporting plate 7 provided with the chuck 10 and the base plate 6 for holding the supporting plate 7 are moved along the guide rail 5 by the roller moving device composed of another air cylinder 13 attached to one side wall 4, and the central shaft 9 of the rubber roller 8 is guided. Can move in a direction orthogonal to.

Below the base 2 of the pillar 1, a long adhesive tape 14 is provided.
There is provided a tape supply device 16 for supporting the supply roll 15 around which the adhesive roll 14 is fed from the supply roll 15.
Is inserted between the chuck 10 provided on the support plate 7 and the receiving plate 3 with the adhesive surface facing the rubber roller 8 side and the longitudinal direction orthogonal to the central axis 9 of the rubber roller 8. Further, a tape winding device 17 is provided below the base 2 of the column 1, and the winding roll 18 thereof is rotated by a winding motor 19 so that the adhesive tape 14 is sequentially wound from the tip side. There is. Since the winding motor 19 has a brake mechanism and the tape supply device 16 is provided with a spring type brake mechanism 20, tension is constantly applied to the adhesive tape 14 between the supply roll 15 and the winding roll 18. Can be held in a closed state

[Action]

As shown in FIG. 1, the adhesive tape 14 fed from the supply roll 15 is passed over the smooth surface 3a of the receiving plate 3 with the adhesive surface facing upward, and stretched in tension with the winding roll 18. .
On the other hand, the base plate 6 is stopped at one end of the receiving plate 3 and the support plate 7 is raised to the base plate 6 side. In the above cleaning device, the width of the adhesive tape 14 is wider than that of the rubber roller 8 to be cleaned.

Next, the two shafts 10 of the support plate 7 hold the center shaft 9 of the manufactured rubber roller 8 at both ends, and the rubber roller 8 is lowered together with the support plate 7 by the air cylinder 11 for contacting and separating the rollers. , The rubber roller 8 is pressed against the adhesive tape 14 on the receiving plate 3. In this state, when the base plate 6 and the support plate 7 are moved to the other end side of the receiving plate 3 along the longitudinal direction of the adhesive tape 14 by the air cylinder 13 for moving the roller, the rubber roller 8 receives the stopped adhesive tape 14 from the receiving plate. It is pressed against the surface 3a of 3 and rotates while moving. Therefore, if the rubber roller 8 is moved by a distance that makes one rotation or more, the adhesive tape 14
Since it is held in tension, it does not return to the supply roll 15 side or bends, and foreign matter such as fine rubber scraps and dust adhering to the surface of the rubber roller 8 is adhesive tape.
All of them adhere to the adhesive surface of 14, and the surface of the rubber roller 8 is cleaned.

Without raising the rubber roller 8 so that the adhesive tape 14 does not sag, the base plate 6, the support plate 7, and the rubber roller 8 are moved in parallel along the guide rail 5 until they are separated from the other end side of the receiving plate 3, and then stopped. Air cylinder for contact and separation 11
To raise the support plate 7 and the rubber roller 8 to the base plate 6 side,
The rubber roller 8 is separated from the adhesive tape 14, and the cleaned rubber roller 8 is removed from the chuck 10. Further, the base plate 6 and the support plate 7 are returned to one end side of the receiving plate 3 by the air cylinder 13 for moving the roller, and the adhesive tape 14 is wound up by the winding motor 19 as necessary to newly install on the receiving plate 3. After being moved by a predetermined length so that the adhesive surface comes, the above cleaning operation is sequentially repeated for the manufactured rubber roller 8.

In the above embodiment, the rubber roller 8 is moved while rotating the adhesive tape 14 in a stopped state, but the rubber roller 8 may be rotated by moving the adhesive tape 14 without moving the rubber roller 8 or both. It is also possible to rotate the rubber roller 8 by moving simultaneously.

When the width of the adhesive tape 14 is narrower than the width of the rubber roller 8, the adhesive tape 14 is tilted with respect to the central axis 9 of the rubber roller 8 and the entire surface of the rubber roller 8 is rotated to cause the adhesive tape 14 to rotate.
It may be placed so as to contact with.

[Effect of device]

According to the present invention, foreign matter such as fine rubber scraps and dust adhering to the surface of the rubber roller during the manufacturing process can be automatically and continuously removed without damaging the surface.

Therefore, it is possible to contribute to the productivity improvement and the cost reduction of the rubber roller used for the printer of the copying machine or the office automation equipment.
