Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bobbin for a winding device, and more particularly, to a bobbin used for a winding device for winding a wire to form a coil and around which the wire is wound.

[0002]

2. Description of the Related Art Conventionally, as this type of winding device, a device having two rollers for guiding a strand has been proposed (for example, Japanese Patent Application Laid-Open No. 7-183152). In this device, the two rollers are arranged so as to sandwich the bobbin, and guide the strand so that the strand wound in alignment with the bobbin does not shift sideways. It is said that by providing such a roller, the element wire can be wound without any gap.

As another winding device, there has been proposed a device having a member for guiding a wire to be wound (for example, Japanese Patent Application Laid-Open No. 64-43046). In this device, two guide members are provided so as to sandwich the winding frame, and the guide members are alternately shifted in a direction in which the guide members can be wound by one pitch when winding the element wire. It is said that such an operation allows the wires to be aligned and wound.

[0004]

However, in any of the above winding devices, there is a problem that the wires wound around the winding frame cannot be densely wound due to a slight gap when the rows are changed. . In the above-described apparatus, the wires wound in alignment are guided, but the "S" curve required for the shape of the wires when the wires are switched is not guided. Will occur. Such a gap leads to a decrease in the number of turns of the coil formed by winding the element wire, and affects the performance of a device using the coil, for example, an electric motor or a generator.

[0005] As a winding device for solving such a problem,
The applicant has disclosed a winding device provided with a means for forming a strand change portion of a wire (Japanese Patent Application No. 11-13051) and a winding device provided with a wire row transition means (Japanese Patent Application No. 11-28867). Etc. are proposed.

[0006] It is an object of the present invention to provide a winding frame for a winding device, which is used for the winding device proposed by the applicant. Another object of the present invention is to make it possible to easily remove a wound coil.

[0007]

Means for Solving the Problems and Action / Effect The winding frame for a winding device of the present invention employs the following means in order to at least partially achieve the above object.

A winding frame for a winding device according to the present invention is used in a winding device for winding a wire to form a coil, and is a winding frame around which the wire is wound, wherein at least two or more members are wound. A core having an expandable / contractible diameter around which the element wire is wound, diameter fixing means for fixing the core in an expanded state, and provided on both sides of a rotation axis of the core extending across the core. In addition, the present invention is characterized in that a grip portion is provided which is capable of gripping the winding frame from both sides of the rotating shaft by the winding device.

In the winding frame for a winding device according to the present invention, the element wire is wound with the core fixed in a state where the diameter of the core is expanded by the diameter fixing means, and the diameter of the core is reduced after the winding of the coil is completed. Can be removed. In addition, since the grip portions are provided on both sides of the rotation axis of the core, the coil can be wound by re-grip the reel.

In the winding frame for a winding device of the present invention, the core is expanded and contracted into a substantially rectangular shape having four corners, and is constituted by four members each including one of the four corners. It can also be. In the winding frame for a winding device according to the aspect of the present invention, the four members of the core are formed with a wedge surface at a central portion of the core when the core is formed. May be a bar member which is inserted into the center of the core and has an inclined surface which comes into contact with the wedge surface of four members of the core. Further, in the winding frame for a winding device in which the core is composed of four members, the four members of the core are formed with a wedge receiving portion capable of inserting a wedge on an outer peripheral surface between adjacent members. The diameter fixing means may be wedges insertable into wedge receiving portions of the four members of the core.
