止め機構に関するものである。[Detailed description of the invention] The present invention relates to a wire starting end stopping mechanism in a wire winding device, and in particular, to a mechanism for properly pulling out the end of a wire wound on a bobbin without bending the starting end of the wire when the wire is drawn out. The present invention relates to a mechanism for stopping the starting end of a wire.

されつつボビンに巻取られていく。 Conventionally, as this type of mechanism, the one shown in FIGS. 1 and 2 is generally well known. That is, in these figures, a bobbin 1 is held between a pintle 2 that moves forward and backward by a pressing means (not shown), and a driving flange 3 that is rotationally driven by an electric motor (not shown). By the way, the bobbin 1 has a double concentric cylindrical shape with one end open.Bobbin flanges 1b and 1c are formed at both ends of the outer cylinder side of the winding drum 1a, and a small hole is formed at the intersection corner of the winding drum 1a and the bobbin flange 1c. 1e is formed. 1d indicates a hollow body. In order to lock the starting end Wo of the wire W to such a bobbin 1, the starting end Wo is bent into a hook shape as shown in FIG.
It is sufficient to simply hook it into the small hole 1e formed in one corner of the hole 1e. When the starting end of the wire W is fixed in this way, the bobbin 1 is rotated in the direction of arrow A by the rotation of the drive flange 3, and the wire W is guided in the width direction of the bobbin 1 by a traverser not shown in the figure. It is wound onto a bobbin.

る。 However, when the wire bundle wound as described above (so-called fully wound bobbin) is unwound and used for manufacturing and processing of various products, the following disadvantages occur. That is, the locking relationship between the wire W and the bobbin 1 at the end of unwinding is again in the state shown in FIG.
Since the wire cannot be pulled out from the wire (hereinafter referred to as "edge pulling out"), this locking portion had to be cut, which caused problems in terms of work efficiency and wire yield. On the other hand, the wire may be pulled out by straightening the bend in the wire starting end Wo, but since the above correction is insufficient, a bend remains in the starting end Wo, and the wire is sent to various devices in this state. When paid,
There is a problem that the wire guide member provided near the device entrance and the device using the wire, such as a welding torch, may be damaged. However, with a relatively flexible wire, it is possible to pull out the wire and feed it without causing such a situation, but in this case, it is difficult to securely secure the starting end of the wire, so it is difficult to wind the wire. The problem arises that it cannot be performed properly.

端止め機構を提供しようとするにある。 The present invention was developed in view of these circumstances, and its purpose is to securely secure the starting end of the wire, regardless of whether the wire is hard or soft, and to prevent bending, etc., from occurring at the starting end of the wire during unwinding. An object of the present invention is to provide a wire starting end stopping mechanism that can effectively perform end slipping without causing the wire to fall out.

る点に要旨を有するものである。 However, the wire start end stop mechanism of the present invention that has achieved such a purpose is held under pressure between the driving flange and the fixing pintle, and the wire start end stop hole is connected between the bobbin winding trunk and the bobbin flange. In a wire start end stop mechanism for a wire winding device in which a wire is wound around a hollow bobbin formed at an intersecting corner, the drive flange is provided with a long cavity extending in the radial direction of the flange; A spring is telescopically fitted in the cavity so as to be unevenly distributed toward the center of the flange, and a small protrusion having a length that reaches the starting end stopper hole forming position is provided at the distal end of the spring on the distal side of the flange. A projecting piece is movably provided in the long cavity, and the flange is further provided with means for penetrating a hole communicating with the long cavity and moving the small protrusion towards the center of the flange. The main points are as follows.

い。 Next, the procedure for actually stopping the starting end and winding the wire using the wire winding device equipped with the wire starting end stopping mechanism configured as described above will be explained with reference to the drawings. 8A to 8C to 10 are explanatory diagrams showing the procedure for fixing the starting end of the wire. First, as shown in FIG. 8A, the bobbin 1 is attached to the driving flange 4.
The bobbin 1 is inserted between the piston 2 and the piston 2, and the piston 2 is moved forward by an air cylinder (not shown) to sandwich the bobbin 1 between the piston 2 and the driving flange 4, and then the air cylinder 13 is actuated. and push the piston rod 12. As a result, the small protrusion 10 is pushed down by a predetermined amount. In this state, as shown in FIGS. 8B and 9 (-arrow view in FIG. 8B), the wire W is held in a straight state without bending its starting end Wo (that is, the elastic limit of the wire W is (inside) Pass through the small hole 1e of the bobbin 1 and insert it a predetermined length into the hollow body 1d. After this, when the air cylinder 13 is operated again to raise the piston rod 12, the small protrusion 10 is pushed up by the elastic force of the compressed spring 8, and as shown in FIGS. As shown in the - arrow view of C), the wire starting end Wo is pressed against the inner circumferential surface of the winding drum 1a. In this way, the wire starting end fixing operation can be carried out quickly and reliably. Thereafter, when the driving flange 4 is rotated by a motor (not shown), the wire W is wound onto the bobbin 1 via a pinch roller and a traverser (not shown). In order to remove the bobbin 1 that has been wound up in this way from the driving flange 4, the air cylinder 13 is operated again to push the piston rod 12 and the small protrusion 10 is pushed down. In this way, a fully wound bobbin in which the wire starting end Wo is kept in a straight line is obtained. Therefore, when the wire W is rewound from such a fully wound bobbin, the end can be pulled out very easily, and since the wire starting end Wo is not bent, the wire guide member will not be damaged. .
