Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a taping wheel and a tape winding device using the taping wheel, and more particularly to a taping wheel for winding an insulating tape piece around an electrically connecting portion of a combined electric wire composed of a plurality of electric wires and the tape winding wheel. The tape winding device used.

[0002]

2. Description of the Related Art A large number of combined electric wires are used in wire harnesses for automobiles and electric equipment and subassemblies (hereinafter collectively referred to as "wire assemblies") that constitute wire harnesses. The combined electric wire is an electric wire to be a branch wire that is electrically connected by intermediately stripping an intermediate portion of the covered electric wire to be a main wire. In general, it is necessary to wind an insulating tape piece around the connecting portion (hereinafter, referred to as “splice portion”) of the combined electric wire in order to ensure insulation. Therefore, various devices have been proposed for automatically winding an insulating tape piece around a splice portion of a combined electric wire.

For example, the devices disclosed in Japanese Utility Model Publication No. 57-18380 and Japanese Patent Application Laid-Open No. 7-057840 have a rotatable substantially cylindrical taping wheel. The taping wheel has an electric wire attaching / detaching port for attaching / detaching the splice portion of the combined electric wire. The electric wire attaching / detaching port is opened on the outer peripheral surface of the taping wheel and penetrates in the axial direction of the taping wheel. Usually, the wire attachment / detachment port is defined by facing a pair of brushes fixed to the taping wheel, and after supplying the splice part between the brushes together with the insulating tape piece, by rotating the taping wheel,
A piece of insulating tape is rubbed on the splice and wrapped around.

[0004]

The splice portion of the combined electric wire constitutes a large-diameter portion in which the main wire and the branch wires are bundled and a small-diameter portion in which only the main wire is present. On the other hand, in each of the above-described conventional devices, the wire is fixed to the taping wheel so that the opening width of the wire attaching / detaching port (the tangential direction of the taping wheel) is always constant. Therefore, it was not possible to achieve both good and reliable winding of the insulating tape piece and easy operability. That is, in order to achieve good and reliable winding performance, it is necessary to narrow the opening width as much as possible and apply a reliable clamping force to the small diameter portion of the splice portion. However, in that case, it is difficult to introduce the large-diameter portion into the electric wire attaching / detaching port, and it is impossible to avoid the problem that the operability is deteriorated. On the other hand, if the opening width is set to be large in order to facilitate the introduction of the splice portion into the electric wire attachment / detachment port, taping of the small diameter portion of the splice portion becomes insufficient, and a gap is created, which causes tape misalignment.

In the device according to Japanese Utility Model Publication No. 57-18380, since the wire attaching / detaching port set to have a constant opening width is open on the outer peripheral surface of the taping wheel in parallel with the axis of the taping wheel, The taping performance could not be improved. On the other hand, the above-mentioned JP-A-7-
In the device according to Japanese Patent No. 057840, since the wire attaching / detaching port is obliquely intersected with the axis of the taping wheel, good taping performance can be ensured, but the opening width of the wire attaching / detaching port is constant. Since each brush is fixed to the taping wheel as described above, it is still difficult to achieve both operability and good taping performance.

The present invention has been made in view of the above problems, and a taping wheel and a tape winding device using the taping wheel that can achieve both the operability of taping work of a splice portion of a combined electric wire and good taping performance. The challenge is to provide.
