DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a taping device for a wire bundle assembly and a taping method using the same.

[0002]

2. Description of the Related Art A wire harness and a sub-assembly (hereinafter, collectively referred to as a "wire bundle assembly") constituting the wire harness are electrical wirings composed of a large number of wires, terminals, connectors and the like incorporated in automobiles, copying machines, and the like. System. Such a wire bundle assembly is subjected to a stripping step of stripping an end of the wire cut to a predetermined length by a production facility for automatic production, and a crimping step of crimping a terminal to a core wire of the wire exposed in the stripping step. And a terminal inserting step of inserting the crimped terminal into the connector housing and the like (see, for example, JP-A-1-313872).

[0003] Since the above-mentioned wire bundle assembly is a product whose main part is a large number of wires and whose form is difficult to be specified, for example, it is easy to come apart, the wire bundle assembly is configured as a product specification. There is a case where a temporary tape fixing to tape the bundle of electric wires is required. Such a temporary tape stop,
From the viewpoint of automating the production of the wire bundle assembly, it is preferable to perform the production automatically. Therefore, a method or apparatus for automatically winding a bundle of wires constituting a wire bundle assembly with a tape has been proposed.

[0004] For example, the above-mentioned Japanese Patent Application Laid-Open No. 1-313872 discloses a technique of bundling a wire bundle constituting a wire bundle assembly with a tape (page 8, upper left column, lines 4-5). Alternatively, Japanese Unexamined Patent Publication (Kokai) No. 64-63285 discloses that an electric wire is laid on a clamp fixed to a conveyor extending in a predetermined conveying direction, and the electric wire laid on the conveyor is arranged along the conveying direction over the entire length. 2 and FIG. 7 disclose a configuration in which the wires of the wire bundle assembly are temporarily taped.

[0005]

None of the above prior arts discloses a specific structure for temporary tape fixing.
Temporary tape stops are currently performed exclusively by hand.
However, when a part to be bound as a product specification is manually performed, there is a problem that workability is poor and production cannot be performed efficiently.

In the case of the structure disclosed in Japanese Patent Application Laid-Open No. 64-63285, it can be considered that temporary tape fixing can be performed to some extent automatically. Since the length of the electric wires along the entire length of the wire bundle is set along the conveyance direction, a long conveyance line is required even when a temporary tape is fixed to the outer periphery of a relatively small wire bundle assembly. It is costly and not practical.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has a practical taping device for a wire bundle assembly and a taping method using the same, which can automatically apply temporary tape fixing to the wire bundle assembly. It is intended to provide.

A taping unit that winds the tape around the wire bundle,
And a cutting portion disposed on the downstream side of the taping portion in the path and cutting an excess length of the tape wound around the wire bundle.

According to a second aspect of the present invention, there is provided a taping method using the taping device according to the first aspect,
The wire bundle assembly manufactured by the production equipment is bundled, the wire bundle of the bundled wire bundle assembly is handled, tension is applied, and the wire bundle is removed while maintaining the tension applied to the wire bundle assembly.
In the radial direction of the
While passing, wrap the tape around the wire bundle and wind
The taping method is characterized in that taping is performed to cut a surplus portion of the attached tape .

[0010]

[Action] In the configuration according to claim 1, a path which is defined in the body portion while the wire bundle passes in one direction, wound on one side sticky tape, the extra length portion is cut by the cutting portion . Thus, the wire bundle assembly is temporarily taped only by passing through the path defined by the main body.

According to the second aspect of the present invention, first, an electric wire bundle assembly whose form is not specified is bundled and brought into a state of being easily transported. Further, the bundle of electric wires of the bundled electric wire bundle assembly is handled so that taping becomes easy. Then, the wire bundle passes through the path of the taping device and is subjected to taping while maintaining the state in which taping is easy to maintain.

The adhesive portion of the adhesive tape 304E at the downstream end of F (the portion indicated by in FIG. 25) faces the bent portion indicated by while covering the wire bundle A1.

In this state, the electric wire bundle A1 further moves through the path PH.
To the downstream side, the adhesive tape 304E becomes the electric wire bundle A1.
In a state where is completely rotated, the portion indicated by the symbol in FIG. 25 is joined to the portion indicated by the symbol. After joining, adhesive tape 3
The part 04E is bonded to the part upstream from the part shown above while the part sticking to the downstream end side of the concave surface 304B is peeled off from the concave surface 304B, as shown in FIG.
The adhesive surfaces are in an overlapping state. Then, the wire bundle A1 exits downstream from between the cam 304A and the taping wheel 304D and approaches the cutter cam 304H.

As shown in FIG. 27, the wire bundle A1 now taped is connected to the cam portion 304J of the cutter cam 304H.
27, the cutter cam 304H rotates counterclockwise in FIG. 27, and the cam portion 304J retreats into the second main body portion 302, allowing the wire bundle A1 to advance, and Cutter 3 retracted into main unit 302
04K enters the path PH, and the adhesive tape 304E
Trim the extra length. As a result, as shown in FIG. 28, temporary tape fixing of the wire bundle A1 is achieved.
