Abstract

PURPOSE:To make it possible to perform naturally well-ordered winding to cope with small-sized electronic components by installing a pulley which serves as a wire winding guide over a base shaft set up in parallel with a core member, with the pulley freely slidable and rotatable over the base shaft. CONSTITUTION:A core member 2 is installed over a rotary shaft 1, with a base shaft 3 set up in parallel with the core member 2. The base shaft 3 is set up on a location-adjustable support arm 4 so that the relative distance from the core member 2 is adjustable. Over the base shaft 3 is installed a pulley body consisting of a thrust bearing 5 of nylon or the like and a pulley 7 with a bearing 6 interposed in between. While a wire 8 is wound via the pulley 7 over the rotating core member 2, travel of the pulley 7 along the base shaft 3 according to the winding process is affected by friction between the base shaft 3 and the pulley 7, tension of the wire 8, and the distance between the pulley 7 and the core member 2. Winding work is performed with the aforementioned factors suitably adjusted. Thus, without any special control, naturally well-ordered winding can be performed, making it possible to cope with the need for the small size required of electronic components.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an aligned winding device for manufacturing wire-wound parts such as relays and chokes which are parts of facsimiles and other electronic and electrical equipment.

(Prior art) The winding parts of relays, chokes, etc. used in electronics, electric ceramics, etc. have a conductor wire with a diameter of several tens of microns to several hundred microns in the core material (for example, the outer shell of the actuator in a relay). There are two winding methods: one in which the wire to be wound is supplied to a rotating core, and the other in which the conductor is wound around a fixed core (the so-called flyer method).

In the former method, a winding supply guide is mechanically moved back and forth in the direction of the rotational axis of the core material as a means for winding the core material evenly (for example, Utility Model Publication No. 59-7624), and in the latter method, is made by mechanically reciprocating the core material or the winding body in the axial direction (for example,
37888).

(Problem to be solved by the invention) If the winding wire to be wound is moderately thick (with a diameter of 1 mm or more), it is possible to wind the winding wire in an aligned manner by controlling the reciprocating motion described above. However, when winding thin wire (with a diameter of several tens of microns to several hundred microns) at high speed, it is difficult to wind the wire in an aligned manner using the reciprocating motion.

Therefore, at present, high-speed winding of thin wire is manufactured by performing reciprocating motion of a guide or the like corresponding to a pitch several times the diameter of the winding wire.

However, in the case of parts that require miniaturization, the above-mentioned winding method increases the winding diameter and cannot meet the demand for miniaturization.

(Means for Solving the Problems) According to the present invention, the feeding guide of the winding wire is not controlled mechanically, but is controlled by the winding itself. That is, the base shaft is installed parallel to the axis of the winding core material,
A pulley for guiding the wire to be wound is mounted on the base shaft,
The pulley rotates freely and also slides arbitrarily on the base shaft.

Therefore, if the end of the wire to be wound (hereinafter referred to as the winding wire) is fastened to the core material or other material and winding is started with the pulley slightly removed from the core material, the tension of the winding wire itself will When the winding is wound adjacent to the wound wire and the winding position changes, the pulley is pulled on the winding and moves on the axis, automatically. The wires are wound with a constant delay angle and the wires are aligned. In addition, when the winding diameter becomes thicker than the previous winding layer at the end of the core material, the winding will naturally slide down to the lower part of the winding layer due to the tension of the winding, resulting in several windings. When the winding is carried out and the winding position moves forward from the pulley position, the above-mentioned delay angle is naturally created and aligned winding is performed.

(Example) Embodiments of the present invention will now be described based on the drawings.

Figures 1 and 2 show a method in which wires are wound around a rotating core material, in which a core material 2 is attached to a rotating shaft 1 and a base shaft 3 is installed parallel to the rotating shaft 1. 3 protrudes from a position-adjustable support arm 4 so that the relative position between the base shaft 3 and core material 2 can be adjusted. A pulley body to which a pulley 7 is attached is inserted into the base shaft 3 via a pulley 7.

The winding 8 is wound onto the rotating core 2 via the pulley 7, and in order for the pulley 7 to move on the base shaft 3 in response to the winding, the friction between the base shaft 3 and the pulley 7 is required. , is determined by the tension of the winding and the distance between the pulley 7 and the core material 2,
The winding operation is performed under optimal conditions by adjusting these factors as appropriate.

The present invention can also be applied to a method of winding a wire around a fixed core material as shown in FIG. Core material 2 while feeding
In a winding machine of a known structure, which is provided with a rotary arm 9 that rotates around A pulley 7 may be mounted on the base shaft 3', and the winding 8 may be wound around the core material via the pulley 7.

(Effect of the invention) As described above, in this invention, the pulley that forms the winding guide is attached to the base shaft installed parallel to the core material so that it can thrust freely on the shaft and rotate freely, and the guide can be moved. Since the winding is done by the force of the wire itself, the winding is done naturally without any particular control of the guide section, making it ideal for winding ultra-fine wires where it is difficult to control the guide section. It was able to respond to the miniaturization required for electronic and electrical components.
