Description

  The present invention relates to a wire winding device that winds a wire such as an enameled wire passed through a baking furnace onto a wire winding bobbin, and in particular, a short dummy wire at the beginning of winding of a wire wound on a wire winding bobbin. The present invention relates to a wire rod winding device configured to be drawn out from a wire rod bobbin.

In a wire winding device that winds a wire such as an enameled wire passing through a baking furnace onto a wire winding bobbin, the wire winding bobbin is usually wound directly on the wire winding bobbin from the beginning of winding the wire. A wire rod such as an enameled wire wound around a wire rod winding bobbin is manufactured into a product such as a coil while being fed out of the wire rod winding bobbin. When a product such as a coil is manufactured by winding an enamel wire, an automatic coil winding machine is generally used. In such a case, in order to increase the operating efficiency of the coil winding machine, a long bobbin with a large amount of wire winding is used as the wire winding bobbin so as to minimize the stoppage of the coil winding machine. However, even when a long bobbin is used, when the wire rod bobbin is about to end, the empty wire rod bobbin is replaced with a full bobbin. It was necessary to connect the wire rod end of the wire rod and the wire rod start end of the fully wound wire rod bobbin to be used next.

  As described above, in the case of a conventional wire winding bobbin, it is normal to stop the coil winding machine in order to connect the wire rod end of the empty wire winding bobbin and the wire rod start end of the fully wound bobbin. Was done. For this reason, the efficiency of coil winding work decreases due to the stop of the coil winding machine, and the monitoring work of workers increases because the wire bobbin is monitored by monitoring when the wire bobbin is empty. For this reason, a plurality of coil winding machines may be stopped at the same time, resulting in a decrease in productivity of coil winding work.

  Accordingly, the present invention provides a connection work between the wire rod end of the wire rod bobbin in use and the wire rod start end of the fully wound wire rod bobbin to be used next without stopping the coil winding machine or the like. It is an object of the present invention to provide a wire rod winding device capable of performing a wire rod winding operation in a state where the wire rod start end of the wire rod winding bobbin is led out from the wire rod winding bobbin.

  In order to solve the above-described problem, according to a first aspect, a wire winding device of the present invention includes a turret unit provided with a bobbin mounting shaft for mounting a wire winding bobbin, and a wire winding bobbin mounted on the bobbin mounting shaft. In the wire winding device having a traverse guide for guiding the wire to the bobbin mounting shaft, the dummy wire winding collar and the wire winding bobbin for winding the winding wire for the first dummy are sequentially mounted on the bobbin mounting shaft. The traverse guide is provided with a slide mechanism that can be extended and contracted in the longitudinal direction of the traverse guide.

  In a second aspect, the wire winding device of the present invention is the wire winding device according to the first aspect, wherein the dummy wire winding collar has a flange on one side surface of the trunk. The wire winding bobbin is disposed in contact with one flange, and has a larger diameter than the flange of the wire winding bobbin, and crosses the flange around the outer periphery of the dummy wire winding collar flange. It is a structural feature that a transition groove for the wire to be formed is provided.

  In a third aspect, the wire winding device of the present invention is the wire winding device according to the first aspect, wherein the turret unit has two bobbin mounting shafts, and one of the wire winding bobbins is fully wound. Then, the structural feature is that the turret unit is rotated so that the wire moves to the other wire winding bobbin.

  In the wire winding device of the present invention, a dummy wire winding collar and a wire winding bobbin for winding the winding wire for starting dummy are sequentially mounted on the bobbin mounting shaft of the turret unit, and the tip of the traverse guide A sliding mechanism that extends and contracts in the longitudinal direction of the traverse guide is provided at the portion. With this configuration, at the beginning of winding of the wire that has been supplied through the baking furnace or the like, first, the dummy wire winding collar mounted on the bobbin mounting shaft of the turret unit is used by the traverse guide with the slide mechanism shortened. It is wound up for several turns. When the wire is wound on the dummy wire winding collar for several turns, the traverse guide slide mechanism is extended, and the wire gets over the dummy wire winding collar collar and the wire winding bobbin collar. It moves to the winding drum of the wire winding bobbin and is wound up until the wire is full on the wire winding bobbin. When the wire bobbin mounted on the first bobbin mounting shaft is fully wound, the turret unit rotates, and the dummy wire winding collar and the wire winding bobbin set on the second bobbin mounting shaft are set to the predetermined wire. The traverse guide slide mechanism is shortened again in conjunction with this, and the wire rod is wound around the dummy wire winding collar and the wire winding bobbin mounted on the first bobbin mounting shaft. By the same operation as the case, the dummy wire is wound around the dummy wire winding collar, and the wire is wound around the wire winding bobbin. Such a winding operation is sequentially repeated. Then, the wire winding bobbin that is full of wire is removed from the bobbin mounting shaft. At this time, the dummy wire wound around the dummy wire winding collar is also removed. In this way, the wire winding start end is led out to the outside of the wire winding bobbin. As a result, the winding start end of the wire led out to the outside of the wire winding bobbin can be easily connected to the winding end of another wire winding bobbin.

  Further, in the above wire rod winding device, the dummy wire winding collar is arranged such that a collar portion provided on one side surface of the body portion is in contact with one collar portion of the wire rod winding bobbin, and the wire rod winding is performed. The diameter of the bobbin is larger than that of the bobbin, and a bridging groove for the wire crossing the hook is provided on the outer periphery of the hook of the dummy wire winding collar. By adopting such a configuration, when the sliding mechanism of the traverse guide is extended and the wire moves from the dummy wire winding collar to the wire winding bobbin, the wire passes through the bridging groove of the flange portion of the dummy wire winding collar. The accident that the wire rod is caught by the collar portion of the dummy wire winding collar and is disconnected is prevented, and the wire rod can be moved smoothly.

  Moreover, if the wire winding device has a configuration in which two bobbin mounting shafts are provided in the turret unit, the wire winding can be continuously operated.

  A dummy wire rod take-up collar for winding a dummy wire rod at the beginning of winding is mounted on the bobbin mounting shaft of the wire rod winding device, and can be expanded and contracted in the longitudinal direction of the traverse guide at the tip of the traverse guide of the wire rod winding device With a very simple structure of providing a slide mechanism, the winding start end of the wire wound around the wire winding bobbin can be led out of the wire winding bobbin.

A mechanism 7 is provided. 8 is a guide pulley. Taking the winding of the magnet wire as an example, the winding of the dummy wire is performed by the slide mechanism 7 of the traverse guide 6 in which the winding start WA of the magnet wire W supplied through the baking furnace is first shortened. It is wound on the collar 5 for several turns. When the wire W is wound on the dummy wire winding collar 5 for several turns, the slide mechanism 7 of the traverse guide 6 is extended, and the wire W passes through the transition groove 5C of the flange portion 5C of the dummy wire winding collar 5. The wire rod winding bobbin 4 gets over the flange 4C and moves to the winding drum 4A of the wire rod winding bobbin 4, and is wound around the wire rod winding bobbin 4 until the wire rod W is full. When the bobbin 4 is fully wound, the turret unit 2 rotates and the dummy wire winding collar 5 and the wire winding bobbin 4 mounted on the separate bobbin mounting shaft 3 of the turret unit 2 are in the wire winding position. Moving. At the same time, the slide mechanism 7 of the traverse guide 6 is shortened again, and after the winding start portion WA of the wire W is wound on the dummy wire winding collar 4 by several turns, as in the wire winding operation described above. The wire W is moved to the wire winding bobbin 4 and taken up until it is fully wound. When the wire W is transferred from the first wire winding bobbin 4 to the second dummy wire winding collar 5, the claw provided on the peripheral edge of the bobbin receiving wheel 10 fitted to the bobbin mounting shaft 3 is used. 11, the wire W is cut and wound around the second dummy wire winding collar 5. Such an operation is repeated. By such an operation, the winding start end WA of the wire W wound on the wire winding bobbin 4 is held outside the wire winding bobbin 4 for several turns. When the wire winding bobbin 4 that is full of the wire W is removed from the bobbin mounting shaft 2, the wire winding start end WA wound on the dummy wire winding collar 4 is also removed. In this manner, the winding start end WA of the wire W is held together with the wire winding bobbin 4 and is taken out. Therefore, by using the winding start end WA of the wire W held outside the wire winding bobbin 4, it is possible to very easily connect the wire winding bobbin 4 to the wire winding end. become.
