Title:
TRANSFER DEVICE FOR LONG ARTICLE
Document Type and Number:
Japanese Patent JP3947909
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve the problem that it is difficult to stably supply a long article such as a wire in simple construction.
SOLUTION: A wire 1a is supplied from a supply-side spool 20 to a winding- side device. The tension of the wire 1a is detected by a dancer tension detector 24. A supply-side motor 21 is controlled by an inverter 22 so that the tension of the wire 1a is kept constant. A circuit is provided in a control circuit 23 for determining the level of a detected tension value Vt and the time constant of a proportion plus integration circuit is changed with a change in level. When sagging occurs in the wire 1a, the detected tension value Vt is lowered and the supply-side motor 21 is reversed. As a result, the wire 1a is rewound on the supply-side spool 20 to eliminate the sagging of the wire 1a.
