Torsion detection device and torsion correction device for pipe conveyer

Abstract

Abstract PURPOSE:To accurately detect and correct torsion of a belt by nippingly holding a belt side edge with a pair of pinch rollers from inside and outside, and providing a torsion detection device in which guide rollers are made to be work parts and a correction part interlocking with the detection device to the side edge part. CONSTITUTION:A pipe state part of an outward belt 1a is opened, and four right and left parts of an opened part are nippingly held with pinch roller groups 9 of four rollers each from inside and outside. Guide rollers 10 are arranged between two pairs of the rollers 9 and 9. A torsion detection switch device A' in which guide rollers 10 are made to be work parts are formed with guide rollers 10, axes 10a, supporting axes 10b, springs 13, and limit switches 14, etc., and a torsion detection device A is composed of pinch rollers 9 and the device A'. A limit switch 14 is connected to an electric cylinder 16 of a correction roller 15 provided to this side in the carrying direction via a control circuit. Thus a correct detection can be obtained.
