DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a multi-head taping device.

[0002]

2. Description of the Related Art Generally, in manufacturing an electric wiring system such as a wire harness or a subassembly (hereinafter, collectively referred to as a "wire assembly") constituting the wire harness, a joint portion of a covered electric wire called a splice is used. Is formed. In order to cover the splice, a taping device has been proposed in which taping is performed by winding an adhesive tape around a joint portion of a covered electric wire (for example, Japanese Utility Model Publication No. 57-1838).
No. 0).

In the prior art, a tape holder for supporting a wound body on which an adhesive tape is wound, a tape feeding unit for feeding out the adhesive tape from the wound body held on the tape holder, and a tape feeding unit are provided. It has a tape cutting section for cutting the fed adhesive tape into predetermined tape pieces, and a taping wheel for winding the cut tape pieces around a joint portion of a wire assembly. Conventional tape holders carry only one adhesive tape roll corresponding to the joint portion of a covered electric wire to be taped.

[0004]

In recent years, with the diversification of manufactured wire assemblies, the joints formed on the wire assemblies have also been diversified, and accordingly, the taping state in coating the joints has various specifications. Is being requested. But,
It has been difficult for conventional devices to meet such demands.

[0005] For example, there are cases where it is required that the number of turns of the adhesive tape wound around the joint portion be larger than the number of turns set in the taping device. However, in order to increase the number of windings of the adhesive tape, it is necessary to make many changes in the specification of the taping device, and it is difficult to increase the number of windings. In addition, in the covering of the joint portion, there are cases where securing of mechanical strength such as adhesiveness and wear resistance and securing of electrical insulation are both required at a high level, and in such a case, It is necessary to wind a plurality of types of adhesive tapes. However, in the above-described conventional taping device, since only one adhesive tape wound body is supported, it is necessary to frequently exchange the adhesive tape according to the mode of the joint portion.

The present invention has been made in view of the above-described problems, and has as its object to provide a multi-head taping device having good workability and capable of responding to diversifying requests for taping conditions.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a tape holder for supporting a wound body on which an adhesive tape is wound, and an adhesive tape formed from the wound body carried on the tape holder. Feeding section, a tape cutting section for cutting the adhesive tape fed by the tape feeding section into tape pieces of a predetermined length, and a taping wheel for winding the cut tape pieces around a joint section of a wire assembly. And a plurality of rotating cores provided on the tape holder and rotatably supporting the wound body of the adhesive tape, respectively.

[0008] In the invention including this specific matter, since a plurality of winding bodies are carried on the tape holder, when feeding the adhesive tape, the adhesive tape to be fed out can be selectively fed out, or a plurality of wound tapes can be fed out. It becomes possible to feed out the adhesive tapes overlapping. The adhesive tapes carried on each rotary core may be of the same type or of different types.

In a preferred aspect, a guide roller provided in the tape feeding section and capable of guiding an adhesive tape fed from a winding body carried by each rotary core to a tape cutting section in a state where the adhesive tapes overlap each other. Is further provided. In the invention including this specific matter, the adhesive tapes respectively fed from the winding bodies supported by the plurality of rotating cores can be guided by the guide rollers in an overlapping state. Here, the overlapping state of the adhesive tape may be a case where a part partially overlaps, or a case where one part completely overlaps the other.

By being introduced into A, the taping wheel 14 rotates, and the tape piece T is wound around the joint. In the specific example shown in the drawing, as shown in FIG. 2, a coil spring 17 having both ends fixed and curved is suspended, and the abdomen of the coil spring 17 guides the adhesive surface S of the tape piece T. Thus, deformation such as curl winding is prevented.

Referring to FIG. 1, the tape holder 11
Is a first rotary core 11A provided at the upper end of the main body 16.
And a second rotating core 11B disposed behind the first rotating core 11A and supported by the main body 16 via the frame body 18.
And Each of the rotating cores 11A and 11B extends in parallel along a horizontal direction extending to the left and right of the main body 16, and has a projection 110 projecting radially outward from the outer peripheral surface at every 60 ° in the circumferential direction.

Here, in the specific example shown in the figure, the rotating core 11
Since a plurality of A and 11B are provided, it is possible to carry the plurality of adhesive tape rolls R1 and R2 on the tape holder 11 so as to be able to be fed out. In the specific example shown in the drawing, the adhesive tape T1 of the wound body R1 carried on the rotating core 11A has a property of little elongation with respect to a tensile force (for example, a packaging adhesive tape made by Sliontec: product name "Filamen Adhesive"). Tape 9510 "). Regarding the mechanical strength of the pressure-sensitive adhesive tape T1, the tensile strength is 80 kgf / 25 mm, and the strain at break is 32%. On the other hand, as the adhesive tape T2 of the wound body R2 carried on the rotating core 11B, a vinyl adhesive tape having high insulation properties is employed.

Next, the tape feeding section 12 is provided with a surface opposite to the adhesive surfaces S1 and S2 of the adhesive tapes T1 and T2 drawn out of the respective winding bodies R1 and R2 (hereinafter referred to as a "back surface").

1. By performing the taping operation by overlapping T2, the number of turns of the tape piece T wound around the joint portion W1 is more than the number of turns of the taping wheel 14 set in the taping device 10. Can be. Further, even when securing of mechanical strength such as adhesiveness and abrasion resistance and securing of electrical insulation are both required at a high level, as described above, a plurality of types of adhesive tapes T1, By overlapping and winding T2, it is possible to respond to such a request with a single taping operation. Furthermore, even in the case of performing high-mix low-volume production, by using the adhesive tapes T1 and T2 alternatively (only one), the adhesive tapes T1 and T2 can be replaced without frequent replacement of the winding bodies R1 and R2. Since the type can be changed, the type of the adhesive tapes T1 and T2 can be easily changed, and workability is improved.

As described above, according to the present invention, it is possible to feed out an adhesive tape to be fed out alternatively or to feed out a plurality of adhesive tapes in an overlapping manner. By performing the taping operation while overlapping the tapes, the number of windings of the tape piece wound around the joint portion can be increased more than the number of windings set on the taping wheel of the taping device. Also, ensuring mechanical strength such as adhesiveness and abrasion resistance,
Even if the securing of electrical insulation is required at a high level, it is possible to cope with a single taping operation by overlapping and winding a plurality of types of adhesive tapes. . Furthermore, even in the case of low-volume, high-mix production, the use of adhesive tape (only one) allows the type of adhesive tape to be changed without frequent replacement of the wound body. The type of the adhesive tape can be easily changed, and workability is improved.

Therefore, according to the present invention, there is a remarkable effect that it is possible to provide a multi-head taping device with good workability capable of responding to diversifying requests for taping conditions. In particular, when a guide roller is provided, a plurality of adhesive tapes can be fed in a state of being overlapped in a predetermined overlapping state, so that there is an advantage that the feeding of the adhesive tape is ensured.
