Benefits of technology

Enables easy and precise adjustment of the bead ring's winding diameter, eliminating the need for multiple rotational bodies with different dimensions, allowing for flexible formation of bead rings with various diameters.

Problems solved by technology

However, if a bead ring is formed using a winding device described in Patent Document 1, it is difficult to change the winding diameter of the bead ring by not only a great amount, but also by a slight amount.
The aforementioned request is thus difficult to satisfy.

first embodiment

[0027]A winding device according to a first embodiment of the present invention will now be described with reference to FIGS. 1 to 6.

[0028]As shown in FIGS. 1 to 3, a rotary shaft 22 is rotationally supported by a device frame 21 and rotated by a non-illustrated motor. A disk-like base plate 23 is fixed to the distal end of the rotary shaft 22. Segments 25 are arranged in an annular zone (not shown) corresponding to the outer circumference of the base plate 23. The segments 25 each have a shape corresponding to one of the shapes obtained by dividing the annular zone into a plurality of (in the first embodiment, four) sections along the circumference of the base plate. The segments 25 are each supported by the base plate 23 to be movable in a radial direction of the base plate 23 about the rotary shaft 22. When the rotary shaft 22 rotates the base plate 23 in one direction, a wire W is wound on the outer circumference of the segments 25 to form a bead ring B.

second embodiment

[0057]A winding device according to a second embodiment of the present invention will now be described. The differences from the first embodiment will mainly be discussed.

[0058]In the second embodiment, as illustrated in FIGS. 7 to 10, the attachment portion 50 of each segment 25 has two elongated holes 81 each extending in the axial direction of the threaded shaft 38. Screws 54 are threaded onto the support member 45 of the corresponding movable member 41 through the elongated holes 81. In this manner, the attachment portion 50 of the segment 25 is supported by the support member 45 such that the position of the attachment portion 50 is adjustable relative to the support member 45 in a radial direction of the base plate 23. A stepped portion 82, which projects forward, is formed in the inner peripheral end of the front surface of each support member 45. A spacer 83 for setting the radial position of the corresponding segment 25 is provided between the stepped portion 82 and the att...

Abstract

A winding device is provided that includes a base plate that is rotated by a rotary shaft and segments. With rotation of the base plate, a wire is wound on the outer circumference of the segments, which rotate integrally with the base plate, to form a bead ring. The winding device includes an manipulation shaft that is rotated by a handle, and conversion mechanisms that are provided between the manipulation shaft and each of the segments The conversion mechanisms transmit and convert rotation of the manipulation shaft to movement of each segment in the radial direction of the base plate.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is the National Stage of International Application No. PCT / JP2012 / 066006, filed on Jun. 22, 2012. The content of this application is hereby incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]The present invention relates to a winding device for forming a bead ring by winding a wire on the outer circumference of a rotational body.[0003]One such winding device has a groove for winding a wire on the outer circumference of a disk-like rotational body. The rotational body is rotated in one direction to wind the wire in a manner stacked in a layer direction in a state aligned in a row direction in the groove, thus forming a bead ring.PRIOR ART DOCUMENTSPatent Documents[0004]Patent Document 1: Japanese Laid-Open Patent Publication No. 2000-334858SUMMARY OF THE INVENTION[0005]Depending on the intended use, there can be a request for bead rings having different winding diameters. However, if a bead ring is ...
