Problems solved by technology

The guide roller is generally made of metal, so the surface is smooth. Therefore, when the tubular conveyor belt is installed outdoors, slippage is likely to occur when it rains, and the friction force changes locally due to the adhesion of powder, granular objects, etc. , sometimes twisting the conveyor belt

Embodiment Construction

[0029] Embodiments of the present invention will be described with reference to the drawings. figure 1 It is a perspective view of a tubular conveyor belt in which a part of the conveyor belt is formed into a tube shape, and the conveyed object is wrapped in the inside and conveyed. figure 1 In the illustrated tubular conveyor belt, an endless belt conveyor belt 3 is wound around a front pulley 1 and a rear pulley 2, and any one of the front pulley 1 and the rear pulley 2 is rotated by a driving unit such as a motor to make The conveyor belt 3 circulates and moves. The intermediate portion of the outgoing belt on the outgoing side and the intermediate portion of the return belt on the return side of the conveyor belt 3 pass inside a guide frame (not shown) in which a plurality of circular holding rollers are arranged in a substantially endless shape or Made in the shape of a trough. In the manner that the surface (conveying surface) of one side portion 3a of the conveyor b...

Abstract

When permanent magnets (6, 7) embedded in a conveyance belt (3) pass by a plurality of magnetic sensors (8), the magnetic sensors (8) detect a magnetic field of the magnets, and a data collector (9) collects detected signals. A controller (10) compares strengths of the magnetic fields detected by the sensors (8), calculates an angle of torsion of the conveyance belt (3) by the location of the sensor (8) which detects the largest magnetic field, outputs an alarm signal to an alarm (11) according to the angle of torsion , outputs a control signal to a circular holding roller driver (12) provided in a roller supporting device (19) of a circular holding roller to correct the torsion of the conveyance belt. It further outputs a control signal to a rounding roller driver (13) provided in a roller supporting device (21) of a rounding roller to correct the torsion of the belt.

Description

technical field [0001] The present invention relates to a tubular conveyor belt that wraps a conveyed object in a tubular shape by wrapping a portion of a circularly moving endless belt conveyer in a tubular shape for conveying. Background technique [0002] Conventionally, there is known a tubular conveyor belt in which a portion of a circularly moving endless belt conveyor is wound into a tubular shape and conveyed by enclosing conveyed objects such as powder and granular objects inside. In this tubular conveyor belt, the conveyor belt wound into a tubular shape is guided and supported so as to pass through guide rollers (circular holding rollers) arranged approximately in an annular shape. The guide roller is generally made of metal, so the surface is smooth. Therefore, when the tubular conveyor belt is installed outdoors, slippage is likely to occur when it rains, and the friction force changes locally due to the adhesion of powder, granular objects, etc. , Sometimes th...
