Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt traveling path control device for adjusting meandering of a belt traveling path of a belt type conveying device.

[0002]

2. Description of the Related Art Conventionally, an operator manually returns a conveyor belt to a predetermined position when the traveling path of the conveyor belt of the belt type conveyor is out of the predetermined position. Also, by arranging guide rollers on both sides of the traveling path of the conveyor belt,
The conveyor belt restricted the path.
