Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor which is relatively lightweight, is bulky, and is suitable for carrying articles of unspecified shape.

[0002]

2. Description of the Related Art For example, scraps produced by punching corrugated cardboard when manufacturing a corrugated cardboard box have conventionally been transferred and discharged by a conveyor device such as a belt conveyor in a factory. However, in order to receive a large amount of scrap, it is necessary to design a wide width, so that there is a problem that the manufacturing cost becomes high.

Further, in the conventional belt conveyor, if the width is not sufficient, when a light and bulky object such as the above-mentioned scrap is conveyed, and the object is laterally displaced and hits a side plate or the like, the conveyed object is conveyed. Sometimes floated from the belt surface and could not be conveyed properly. Further, since the belt conveyor is generally thick as a device, it may not be installed in a space below the corrugated board punching machine, for example. Furthermore, on the belt conveyor,
There was a risk that small corrugated cardboard chips and the like would get caught between the rollers.
