Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to, for example, end treatment of a three-core cabtire cord.

[Prior Art] In order to connect a coated electric wire to a terminal or perform terminal treatment, it is necessary to remove the coating on the tip end to expose the core wire. In particular, in the case of a coated electric wire twisted in the sheath, the tip of the sheath must first be removed by a required length, and then the exposed coating of the tip of the coated electric wire must be removed. Covered wire 3 after removing the sheath 2a of the sheath wire 1
Is in a twisted state as shown in FIG. 5 (a), the uncovered wire 3 is untwisted in order to remove the above-mentioned coating, and then as shown in FIG. 5 (b). The coated electric wires 3 are arranged in parallel, and further, as shown in FIG. 5 (c), the coating is removed at the tips while aligning them in plan to expose the core wire.

[Problems to be solved by the invention] However, in the past, most of this work is manual work. Further, there is known an apparatus for automatically performing a planar alignment process, but it cannot be efficiently performed.

An object of the present invention is to solve the above-mentioned problems and to provide an electric wire leveling device for planarizing the covered electric wires.

[Means for Solving the Problems] In order to achieve the above-mentioned object, in a wire leveling device according to the present invention, a mechanism for peeling the sheath at the distal end of a sheath wire, a plurality of sheath wires that are peeled and exposed. A device for arranging a plurality of covered wires that have been untwisted in a plane in a subsequent step of a mechanism for returning the twist between the covered electric wires, and holding a sheath peeled portion of the sheath electric wire. Holding means and a pair of upper and lower leveling members for sandwiching the plurality of covered electric wires, and a zigzag vertical direction is applied to the leveling member on the side that moves up or down for sandwiching. By providing a bent groove facing the fixed groove, a fixed pin is inserted into the bent groove, and the bent groove follows the pin in accordance with the upward movement or the downward movement of the leveling member to swing the leveling member left and right. , So that the covered wires are aligned in a plane It is characterized by having done.

[Operation] The electric wire leveling device having the above-described configuration efficiently and automatically arranges a plurality of covered electric wires whose sheaths have been peeled off into a planar shape.

[Embodiment] The present invention will be described in detail based on an embodiment shown in FIGS. 1 to 4.

FIG. 1 shows a front view of an electric wire end treatment device for continuously peeling off the sheath 2a of the sheathed electric wire 1, untwisting the covered electric wire 3, aligning the covered electric wire 3, and peeling the covered electric wire 3, and the infinite caterpillar 10 The sheath electric wire 1 placed thereon is sequentially processed by the first to fifth steps. The first step A is a step of cutting and aligning the tip of the sheath electric wire 1 as shown in FIG. 2 (a), and the second step B is making a cut on the circumference of the sheath 2.
This is a step of separating the sheath 2a at the distal end as shown in FIG. 2 (b). Next, the third step C is a step of pulling out the sheath 2a and returning the twist of the covered electric wire 3 as shown in FIG. 2 (c). The fourth step D is a step of cutting the coating of the coated electric wire 3 and then peeling it off as shown in FIG. 2 (d), but the electric wire leveling device according to the present invention operates immediately before the peeling operation. The fifth step E is a step of twisting the exposed core wire 4 so as not to unwind it as shown in FIG. 2 (e).

3 and 4 show the structure of the fourth step D, FIG. 3 is a side view, and FIG. 4 is a front view. Holding member in FIG.
Reference numerals 11a and 11b are mechanisms for holding the sheathed electric wire 1 when the covered electric wires 3 are aligned in a plane, and are holding members above.
The cylinder 11a moves up and down by the operation of the cylinder 12, and the lower holding member 11b is fixed. In addition, in order to securely hold the sheath electric wire 1, the lower holding member 11b is provided.
The concave portion 13 is provided on the upper portion, and the upper holding member 11a is provided with the convex portion 14 that substantially protrudes into the concave portion 13. On the other hand, a pair of upper and lower pressing members 15a and 15b are provided on the front surfaces of these holding members 11a and 11b, and the pressing member 15a is vertically movable by a cylinder 16. The leveling member 1 is provided on the front surface of the pressing member 15a.
7a is provided, and the leveling member 17a is pulled downward with respect to the pressing member 15a by the spring 18,
The 5a and the leveling member 17a are guided so as to be movable only in the vertical direction. In addition, the long hole portion 1 of the lower pressing member 15b
A shaft 20 is inserted through the shaft 9, the shaft 20 is fixed to a lower frame 21, and a pressing member 15b is pulled upward by a spring 22 hung on the shaft 20. Also, the pressing member 15b
The pin 23 is fixed to the zigzag-shaped bent groove 24 provided on the leveling member 17b provided on the front surface of the pressing member 15b.
A pin 23 is inserted in the pin 23, and the leveling member 17b can swing left and right about the shaft 20.

At the time of the operation of the fourth step D, the sheath electric wire 1 in which the covered electric wires 3 as shown in FIG. As shown in the figure, it is placed on the holding member 11b and the pressing member 15b. Next, the holding member 11a is lowered by the cylinder 12 to fix the sheath 2 of the sheath electric wire 1. And the upper holding member
15a is lowered by the operation of the cylinder 16, and the leveling member 17a
The covered electric wire 3 is sandwiched between the flattening member 17b. Further, when the pressing member 15a descends, the fork-shaped lower end of the pressing member 15a contacts the upper end of the pressing member 15b and moves the pressing member 15b downward against the force of the spring 22. In this process, the pin 23 fixed to the pressing member 15b descends and the bending groove 2
The leveling member 17b having 4 swings left and right around the fixed shaft 20 and descends while leveling the covered electric wire 3. When the operation of the cylinder 16 is completed in this way, as shown in FIG. 2 (d), the three covered electric wires 3 are substantially flatly aligned on the leveling member 17b, and the covered electric wire 3 immediately after that. This makes it easier to remove the skin.

Although the lower leveling member 17b is swung in the embodiment, there is no problem even if the upper leveling member 17a is swung.

[Advantages of the Invention] As described above, the wire leveling device according to the present invention automatically performs the step of aligning a plurality of covered wires in a plane, which is convenient for the next step processing.
