Description

DETAILED DESCRIPTION OF THE INVENTION The return belt of a known pipe conveyor, in which most of the forward route of an endless belt that reciprocates between two locations is rolled into a pipe shape, and powder and granules are wrapped in the pipe and continuously conveyed, is empty. Move at 11.

The present invention relates to a pipe conveyor that uses the above-mentioned empty return belt to further convey other powder and granular materials.

Endless belts used in pipe conveyors have a wear-resistant back surface that contacts the support rollers and an inner surface that wraps around the conveyed object, and cannot be rolled in the opposite direction.

1 fc, if the endless belt is turned upside down and rolled up, objects to be conveyed that adhere to the belt on the outward journey will fall outside on the return journey due to vibrations, etc., and the surrounding environment will be contaminated, which is not desirable.

Furthermore, 1. The overlapping portions of both ends of the rolled endless belt must always be located above so that the conveyed object does not fall out.

However, since the inner surface of the road belt faces downward,
In No. 11, the overlapping portions at both ends cannot be rounded upward.

In the present invention, the endless belt is folded back from the end point of the forward path, the overlapping part is rolled downward again, and the return path belt is held in its pipe shape, and is forcibly rotated around the axis in the traveling direction until 7'C=E.゛After twisting 80 degrees and directing the overlapping part upward, the overlapping part is forcibly opened, other powder and granules are put in, and the material is rolled up into a circular shape again and transported. This invention relates to a reciprocating conveyance rod by a pipe conveyor, which makes effective use of the return belt that was not used in the previous process, and a reciprocating conveyor system for implementing the same.
