Abstract

PROBLEM TO BE SOLVED: To smoothly cut off a tying material by a method wherein a distinguishing sensor to distinguish a tied long object from the tying object and a front end detecting sensor to detect the front end of the tied long object are provided to control the actions of an untying device according to outputs from the sensors. SOLUTION: When a tied long object P is transferred in the direction shown by an arrow R by a conveyer, the front end of the long object P is detected by a front end sensor 9 and the positions of a tying objects B are detected by a distinguishing sensor 8. During the period of time until the front end of the long object P reaches the downstream side of the conveyer, instructions are issued to traverse devices 5 of an untying device according to those signals so that traverse trucks 14 are moved to and held in standby at the positions of the tying objects B. When the front end of the long object P is positioned and stopped by a stopper 10, cutters 15 are lowered by lifts 16 to cut off the tying objects B. The tying objects B that are cut off fall down and are recovered in a scrap bag 11.

[0002]

2. Description of the Related Art Conventionally, long materials such as steel pipes and round bars are generally transported in a state of being bound together by using a binding material such as a hoop or a wire. Then, when processing such a bound long material (hereinafter, referred to as a bound long material) on a secondary refining line or the like, it is necessary to cut and bind the binding material. This unbundling involves waiting several workers in advance downstream of the conveyor for transporting the long material to be bound, stopping the transport conveyor when the long material to be bound is transported, and It is done by means of manually cutting the hoop and the numbered wire using nippers, cutters, and pliers.

In the case of bundling long materials, it is general that they are tied at different positions according to their lengths at three positions, both ends and a central part.
