DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an improvement of a wire handling apparatus for pressure-connecting terminals to ends of a coated wire.
BACKGROUND OF THE INVENTION
As wire handling apparatuses of this type, wire handling apparatuses disclosed in Japanese Patent Publication No. 5-78883 and Japanese Utility Model Laying-Open Gazette No. 3-95519 are known, for example. These wire handling apparatuses are provided in structures of cutting long coated wires into prescribed lengths, peeling off coated parts on both end portions of the cut coated wire, and pressure-connecting terminals to these wire both end portions of the wire from which the coated parts are peeled off.
Making description as to a general structure of this type of wire handling apparatus, it comprises a length measuring unit 1 having a length measuring roller for intermittently delivering a coated wire W by prescribed dimensions, and a front side clamp 2 (hereinafter referred to as an F clamp) and a rear side clamp 3 (hereinafter referred to as an R clamp) serving as clamp mechanisms for grasping the coated wire W are comprised downstream a wire feed direction in the length measuring unit 1, as shown in FIG. 25.
Further, a cutter mechanism 4 for performing cutting and peeling of the coated wire W is arranged between the F clamp 2 and the R clamp 3. In addition, a front side terminal pressing mechanism 5 is arranged on a side portion of the F clamp 2, a rear side terminal pressing mechanism 6 is arranged on a side portion of the R clamp 3, and carriage mechanisms 7 and 8 for carrying the coated wire W which is grasped by the said F clamp 2 and the R clamp 3 to corresponding positions of the terminal pressing mechanism 5 and the terminal pressing mechanism 6 respectively are arranged. Further, a wire discharge mechanism 9 is arranged on a position approximate to the said rear side terminal pressing mechanism 6.
As a handling operation for the coated wire W, the coated wire W is first fed toward the respective clamps 2 and 3 by the said length measuring unit 1 by prescribed dimensions, and the coated wire W is grasped by these respective clamps 2 and 3. In this state, peeling of a coated part and pressure connection of a terminal 10 are already performed in a precedent wire handling step on a feed direction forward end portion (lower end portion in FIG. 25) of the coated wire W.
In this state, cutting of the coated wire W and peeling of coated parts of these cut end portions are performed by the cutter mechanism 4 in an intermediate position between the F clamp 2 and the R clamp 3. Thereafter an operation of pressure-connecting terminals 10 to end portions of this coated wire W is performed. In this pressing operation, the F clamp 2 first moves to the front side terminal pressing mechanism 5 position while grasping the coated wire W, and the R clamp 3 moves to the rear side terminal pressing mechanism 6 position while grasping the coated wire W simultaneously with this (refer to phantom lines).
The operation for pressure-connecting the terminals 10 to the end portions of the coated wire W is performed in the front side terminal pressing mechanism 5 and the rear side terminal pressing mechanism 6 in this state, and thereafter the F clamp 2 returns to the initial position (position shown by the solid lines) while grasping the coated wire W, and the R clamp 3 transfers the coated wire W to the wire discharge mechanism 9 and thereafter returns to the initial position (position shown by sold lines) without grasping the coated wire W. Such an operation is so repeated that coated wires W pressure-connected with the terminals 10 on both end portions are successively manufactured in prescribed lengths.
In the aforementioned wire handling apparatus, however, the F clamp 2 side can make the return operation to the initial position start immediately after the pressing operation while the return operation of the R clamp 3 side to the initial position cannot be started until the pressing operation is performed and the coated wire W is therea
