Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tube-shaped resin member to which a shape-retaining wire (shape-retaining steel wire) is spirally attached to manufacture a supply / exhaust duct or a sheet-shaped resin member made of steel. The present invention relates to a wire rod attaching device for a resin tube used when attaching a wire rod such as a wire in a curved line.

[0002]

2. Description of the Related Art Conventionally, the following has been known as a device for attaching a steel wire to a tubular resin member. That is, a lower roller having a rotation axis parallel to the axis of the hollow body is provided in the internal space of a long hollow body capable of externally holding a tubular resin member (hereinafter referred to as a resin tube). At the same time, the outer peripheral surface of the lower roller is exposed at the opening formed in the hollow body, and the rotation axis of the upper roller corresponding to the lower roller is rotated at a desired angle around an axis (swivel axis) orthogonal to the axis of the hollow body. It was known that it was able to turn.

The operation of winding and attaching a steel wire around a resin tube using such a conventional apparatus is carried out by coating a steel wire and a resin-made steel wire on a resin tube held in a hollow body in an externally fitted shape. The members are fed, the resin tube, the steel wire, and the steel wire coating member are sandwiched between the lower roller and the upper roller to rotate each of these rollers at a predetermined speed, and the feeding force of each of these rollers By blowing hot air while rotating the resin tube, the steel wire, and the steel wire coating member around the hollow body, the resin tube and the steel wire coating member are heat-sealed, and thereby the steel wire is fixed to the resin tube and the steel wire. The method of confining it between the covering member and the covering member is adopted.

In such a steel wire attaching operation, when the steel wire is wound around the resin tube in a spiral shape, the rotation axis of the upper roller is turned around the turning axis by a desired angle so that the upper roller is turned into the resin tube. By setting the direction of the feed force to be transmitted in the direction intersecting the axis of the hollow body, the direction of the feed force by the upper roller is twisted around the resin tube in the twist direction of the steel wire (circumferential direction of the resin tube). The direction of twisting) was adopted.

[0005]

However, while the rotational axis of the lower roller is fixed in a position parallel to the axial center of the hollow body, the rotational axis of the upper roller is swung to feed the upper roller. In the conventional device that had no choice but to align the direction of the steel wire with the twist direction of the steel wire, the rotation direction of the outer peripheral surface of the lower roller did not match the rotation direction of the outer peripheral surface of the upper roller, so the resin tube was There is a problem in that it is difficult to smoothly carry out the action of feeding the resin wire in the axial direction while rotating, and it is difficult to make the pitch of the steel wire spirally wound around the resin tube uniform. Therefore, an auxiliary work is performed in which a worker holds the steel wire fed between the resin tube and the steel wire covering member by hand and determines the feeding angle in a direction perpendicular to the rotation axis of the upper roller. However, since such auxiliary work must rely on the intuition and experience of the worker, the quality of the finished product is not uniform even if the auxiliary work is used together. There was a situation that was likely to occur. Sheet-shaped resin member (hereinafter referred to as resin sheet)
The same was applied to the case where a steel wire was attached in a curved line.

The present invention has been made in view of the above problems, and in the wire rod attaching device to the resin tube, the lower roller is disposed in the internal space of the long hollow body, even though the lower roller is disposed in the inner space. The rotation axis of the lower roller can be rotated by a desired angle around an axis orthogonal to the axis of the hollow body, as in the upper roller, so that the lower roller can be wound around the resin tube in a spiral shape. The rotation direction of the outer peripheral surface of the upper roller to match the rotation direction of the upper roller, and in the wire rod attachment device to the resin sheet, the rotation axis of the lower roller is rotated in the same manner as in the upper roller. By so doing, when the wire is attached by drawing a curve on the resin sheet, the rotation direction of the outer peripheral surface of the lower roller is set to the rotation direction of the outer peripheral surface of the upper roller. And an object thereof is to ensure be matched.

Further, the present invention provides an apparatus for attaching a wire rod to a resin tube capable of continuously performing a work of winding the wire rod around the resin tube and confining the wire rod between the wire rod covering member and the resin tube. The purpose is to
