[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheathed wire stripping mechanism, and more particularly, to a sheathed wire which is driven integrally with a cutting blade for cutting a scaled wire when manufacturing a wire harness. The present invention relates to a stripping mechanism for a covered electric wire, which is most suitable for stripping a wire.

[0002]

2. Description of the Related Art Generally, in the manufacture of a wire harness, a covered electric wire is measured and cut, and an end or an intermediate portion of the cut electric wire is subjected to skinning to expose a core wire. And a step of short-circuiting the core wire to a predetermined terminal. Various devices have been proposed for automating the process of cutting and stripping electric wires.

For example, JP-A-2-46120 and JP-A-3-8217 disclose a pair of stripping blades facing each other across a predetermined wire feeding path. The stripping blades are formed in a V-shape and face each other, and are moved from a wire release position retracted from the wire feeding path to a cutting position where they approach each other and cut the wires. It is configured to cut the covered electric wire in the supply path (hereinafter, this step is referred to as “cutting operation”).

[0004] In Jo <br/> state that remain cut operation is performed, by relatively displacing the peeling blade and the wire in the longitudinal direction of the wire, the covered portion of the electric wire cut into It is to be removed (hereinafter, this step is referred to as “peeling operation”). By the way, since various electric wires (for example, those having different wire diameters and thicknesses of covering portions) are used for the wire harness, it is necessary to cope with various kinds of electric wires in the above-described device. In view of the above, in the above-mentioned cutting operation, a large number of stripping mechanisms of the coated electric wire have been proposed to enable stripping of various electric wires.

[0005] The first aspect is a configuration in which the approach distance of the skinning blade in the cutting operation can be adjusted (for example, JP-A-60-16106, JP-A-61-2).
73114, JP-A-2-21015, JP-A-3-88292, and JP-A-4-1499
No. 83 publication). In these configurations, when performing the cutting operation on the thin electric wire of the covering portion, by adjusting the approaching interval of each peeling blade by manual operation or automatic operation,
The depth of cut by the skinning blade was made to correspond to the type of electric wire.

Further, as a second embodiment, Japanese Patent Laid-Open No. 5-68
The configuration disclosed in Japanese Patent Publication No. 311 is also known. In this configuration, the peeling blade performing the cutting operation is circulated around the electric wire, so that a reliable cutting process is performed. Further, as a third embodiment, Japanese Patent Application Laid-Open
A configuration disclosed in -16106 is also known.
In this configuration, prepare multiple pairs of skinned blades according to the line type,
A configuration is proposed in which a peeling blade can be selected according to the electric wire to be processed. Incidentally, as described above, the cut operation and the peeling operation, and different displacement Direction of peeling blades together, moreover, it is necessary to link the operation timing sequentially. Therefore, in the conventional configuration, a pair of predetermined peeling blades approach each other to the wire feeding path, and a cutting unit that cuts a coating portion of the wire clamped at a predetermined position of the wire feeding path; A stripping unit for stripping the cut portion by moving the stripping blade along the wire feeding path, and a coating fed to the wire feeding path by driving both units. And a stripping carrier for selecting a stripping blade in accordance with the electric wire.

SUMMARY OF THE INVENTION As in the first aspect,
Simply adjusting the cutting depth of the peeling blade has a problem that, depending on the type of wire, many non-cut portions of the covering portion remain, which hinders the peeling operation. In particular, in the case of manual operation, the quality tends to vary depending on the skill of the worker, and setting errors and the like due to human factors are likely to occur. In the case of the automatic operation, the configuration is complicated, and the accuracy of about 1/100 mm is required for controlling the apparatus.

Further, in the second aspect, although the uncut portion of the covering portion can be surely prevented, a structure for rotating a peeling blade for performing a cutting operation and a peeling operation is required. There was a problem that the device became complicated. Further, since the core wire of the electric wire is not always exactly concentric with the covering portion, there is a problem that the peeling blade damages the core wire or cuts off the covering portion when the peeling blade is rotated.

Furthermore, in the third aspect, a dedicated peeling blade can be used according to the line type, so that the above-mentioned problem can be solved. As a result, the peeling blade carrier needs to integrally drive both the cutting unit and the peeling unit, it is necessary to provide a large-sized mechanism capable of driving both units.
Naturally, such a peeling blade changing unit is
The structure becomes complicated and the cost increases. In addition, since the mechanism of the peeling blade carrier becomes large, the types of replaceable peeling blades are restricted, and there is a problem that it is not possible to sufficiently cope with other types of wire harnesses.

Then, by simply rotating the revolver R1 by driving the guide shafts 1055A and 1055B, the desired peeling blade 20 is directed to the electric wire feeding path PH, the pin P is inserted again, and then the bolt is fixed with the bolt B. Is fine.

As described above, both revolvers R1, R2
Is a keyway R14 of the boss R13 and a fitting hole R22.
(See FIG. 6), the connection is made non-rotatable in the circumferential direction, so that the peeling blade 20 in the second revolver R2 can be exchanged only by rotating the first revolver R1. . As described above, in the present embodiment, the first and second revolvers R1, R2
However, a base portion 105A constituting a main part of the cutting unit,
Since it is disposed so as to be able to follow the 105B, it is possible to select the skinning blade 20 according to the line type only by driving a plurality of kinds of skinning blades 20 exclusively. Therefore, in this embodiment, the mechanism for selecting the peeling blade 20 is simplified,
It greatly contributes to product miniaturization. In addition, this makes it possible to increase the types of the peeling blades 20, so that it is possible to cope with other types of wire harnesses.

The revolvers R1 and R2 are connected to the base 10
Simply turning on the guide shafts 1055A, 1055B of 5A, 105B makes it possible to make the stripping blade 20 corresponding to the wire W to be stripped face the wire feeding path PH. Therefore, the layout of the peeling blade 20 can be made compact, which contributes to further downsizing. Moreover, the desired peeling blade 20 can be opposed to the electric wire feeding path PH only by rotating the revolvers R1 and R2, so that the workability is also improved.

Further, in this embodiment, the relative position of each of the revolvers R1 and R2 with respect to the cutting blade 3 is adjusted by the adjusting mechanism 30, so that the cut position by the peeling blade 20 from the end of the cut electric wire W can be set as desired. It becomes possible to change to dimensions. Therefore, there is an advantage that the specification of the peeling can be easily changed according to the type of the terminal to be crimped in the subsequent step.

As described above, according to the present embodiment, it is possible to provide a small-sized peeling mechanism 10 which is inexpensive, has good workability, and is compatible with other types of wire harnesses. It should be noted that the above-described embodiments are merely examples of preferred specific examples of the present invention, and the present invention is not limited to the above-described embodiments. For example, in the above-described embodiment, the apparatus is embodied as an apparatus that integrally cuts and strips the electric wire W. However, for example, a dedicated stripping machine as disclosed in JP-A-60-16106 is used. It is of course possible to adopt it. Also in this case, it is needless to say that the revolvers R1 and R2 can be employed and driven by the cutting unit, whereby the size can be significantly reduced as compared with the prior art.

Further, in the above-described embodiment, the configuration in which the revolvers R1 and R2 are rotated by manual operation is adopted. However, the configuration in which the revolvers R1 and R2 can be automatically rotated by using a known driving mechanism is adopted. Good. Further, the present invention is not limited to an apparatus for peeling an end of an electric wire, but may be applied to an apparatus for peeling an intermediate part of an electric wire, such as an apparatus disclosed in JP-A-3-8217. It is.

It goes without saying that various design changes can be made without departing from the spirit of the present invention.
