Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for installing a rubber sheet on a pallet, and more specifically, a rubber sheet mixed with short fibers rolled by a calendar or the like is bevel-cut on both sides of the rubber sheet to make a canvas or the like. The present invention relates to an apparatus for installing a rubber sheet on a pallet, which automatically cuts the rubber sheet wound around the liner and installs it on the pallet with the liner.

[0002]

2. Description of the Related Art In a rubber sheet containing short fibers, short fibers are generally mixed in the rubber by a calendar. In this rubber sheet, short fibers are arranged in the sheet extruding direction, and it is used for a compression rubber layer such as a low edge belt and a multi-ribbed belt among power transmission belts. The short fiber-containing rubber sheet, after being rolled by a calender, is directly supplied to a winder consisting of a roll having a liner such as canvas wound thereon and a roll for winding this liner, and the rolled rubber sheet is a liner. It was continuously wound while being piled up.

After moving the winder to a predetermined position, an operator pulls out the rubber sheet from the winder and cuts it into a predetermined length with a cutter, and further bevels both sides of the rubber sheet. That is, the end was cut in the bias direction. This bevel cut is also an important step for joining short-fiber-containing rubber sheets cut into a certain length without steps. A plurality of rubber sheets cut to a certain length were laminated on a pallet installed on a movable carriage together with a liner made of a synthetic resin film such as polyethylene, and then the carriage was moved to a belt forming step.

[0004]

However, both the cutting and the bevel cutting process depended on the operator. In particular, in the cutting step, a worker cuts a rubber sheet pulled out from a winder into a predetermined length, and then stacks the rubber sheet on a liner and installs it on a movable carriage. This process is close to manual work, and it has been strongly desired today to rationalize it. The present invention is to improve such a problem, and to automatically cut a bevel-cut rubber sheet wound on a winder into a predetermined length, and install the rubber sheet on a pallet together with the lining. It is an object to provide an installation device for a pallet.

[0005]
