2. Description of the Related Art Conventionally, in order to mirror-finish (glossy) a surface of a resin plate or the like, a method of hot pressing a resin plate with a mirror-finished metal plate, that is, a mirror-finished plate has been adopted. Usually, as the mirror surface plate, a sheet-like plate having substantially the same size as the resin plate to be processed is used. By the way, this mirror plate
Dirt accumulates during use and requires cleaning at an appropriate time. In particular, when using a resin plate coated with a varnish for giving gloss to the surface, the varnish adheres to the mirror plate in a relatively short period of time, and if this is not removed,
At the portion where the varnish adheres, the contact thermal resistance from the mirror plate to the resin surface decreases, the amount of heat transfer increases, and the heating of the resin plate surface becomes non-uniform, thereby deteriorating the quality of mirror finishing.

Therefore, conventionally, a cleaning device is provided separately from the mirror processing device, and the mirror plate is put into the cleaning device at an appropriate time for cleaning. As the cleaning device, one using ultrasonic cleaning or cleaning with high-pressure water has been used, and both have been configured to perform cleaning in a cleaning tank.

[0005] Recently, the present applicant has developed a mirror processing apparatus using an endless mirror plate, but since the endless mirror plate is incorporated in the apparatus, a problem has arisen in this cleaning. In other words, there is a problem that a large amount of labor is required for the operation of removing the cleaning device and putting the cleaning device into the cleaning device, and a very large cleaning device must be prepared. Therefore, it is conceivable to incorporate the cleaning device into the mirror processing device to perform the in-line cleaning of the mirror plate, but it has been difficult to incorporate a conventional cleaning device having a cleaning tank into the mirror processing device.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a mirror plate cleaning apparatus that can be easily incorporated into a mirror processing apparatus to clean the mirror plate. .

[0007]

A stepped bar having a convex portion on the side facing the cloth for use, a cushion material disposed between the stepped bar and the cloth for cleaning, and the stepped bar to the cloth for cleaning via the cushion material. In this configuration, a pressing means having a pressing mechanism for pressing is used. In this way, by adopting the method of wiping the mirror surface with the cleaning cloth,
It does not require a cleaning tank like a conventional cleaning device, and can perform cleaning on any of a sheet-like mirror plate, a long web-like mirror plate, and an endless mirror plate.
By using the cleaning cloth supply means provided with the cloth feeding roll and the cloth take-up roll for supplying the cloth, the cleaning apparatus can be made compact and can be easily incorporated into the mirror finishing apparatus. Further, the cleaning cloth is pressed against the mirror plate by the stepped bar via the cushion material, so that the cleaning cloth can be pressed against the mirror plate without uneven pressure and with a large contact pressure, and the uneven cleaning can be achieved. Can be washed without. Thus, the mirror-surface plate can be satisfactorily cleaned in-line by being incorporated into the mirror-surface processing apparatus.
