Apparatus for axially shifting wire segments in belt type conveyor

摘要

A machine cuts elongated wire segments from a continuous wire strand. A belt type conveyor conveys each segment in incremental steps along a path, with the axis of each segment transverse thereto. The conveyor initially grips a segment near one end and presents it to a first terminal attachment machine on one side of the conveyor where a first terminal is attached. Then, separator devices cause the conveyor to temporarily release its grip on the wire segment to allow wire shifter devices, first, to axially shift the wire segment very rapidly a great distance so that the conveyor can regrip the wire segment near its other end and, secondly, to axially shift the wire segment slowly for a short distance to precisely position its opposite end in final position wherein a second terminal attachment machine on the other side of the conveyor attaches a second terminal to the opposite end. A control system comprises sensors for determining when the wire segment has been moved by the wire shifters. Each sensor comprises separable electrical contacts between which a wire segment is received and which bias closed to provide a control signal when the wire segment is withdrawn axially by a wire shifter device. The contacts of one sensor are movable near the conveyor to initially receive the drooping end of a wire segment and are movable away from the conveyor to ensure proper timing of contact closure.
