US 5,913,469 A · Method of and apparatus for ensuring a wire feed amount in manufacturing of wire harnesses

Abstract

Press rollers for being pressed respectively against wires are provided on an upper side of the wires while length-measuring rollers for respectively contacting the wires are provided on a lower side of the wires. A number of revolutions of each length-measuring roller is detected by an encoder, and an amount of actual feed of each wire is detected in accordance with its revolution number, and a pulse signal, representing its detection value, is sent to a comparison processing portion of a controller. In this comparison processing portion, the amount of actual feed of each wire, detected by the encoder, is compared with a predetermined feed amount of a feed roller beforehand given as an instruction to the processing portion, and if there is any difference between the two, an instruction is given to a servo amplifier, and the servo amplifier sends an instruction to a servo motor for driving the feed roller so as to rotate the servo motor in a normal or a reverse direction in accordance with this difference.

Dependent claims

A method of ensuring a wire feed amount in a manufacturing of wire harnesses comprising:

feeding a plurality of wires a set length by driving a feed roller with a motor;
detecting an actual feed amount of each of the plurality of wires being fed by the feed roller independent of the feed roller and the motor;
comparing said actual feed amount with said set length given as an instruction to said feed roller;
and
controlling a rotation of said motor so that said actual feed amount coincides with said set length, when a difference between said actual feed amount and said set length is more that a set tolerance.
