[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a multi-winding winder for winding two or more wires such as electric wires around the same bobbin at the same time. More specifically, when winding multiple wires around the same bobbin at the same time, the wire end is chucked. Regarding technology.

[0002]

[Prior art]

 Conventionally, a plurality of bobbin pans that are driven by a motor are placed on the turntable, and the bobbin is placed on the pan to rotate the bobbin. There is known a winding machine that rotates and sets a tray on which an empty bobbin is placed at a wire winding position.

In such a wire rod winding machine, in order to smoothly perform the transfer of the wire rod from the full bobbin (the bobbin in which the wire rod has been wound up) to the empty bobbin, the wire rod between the wire rod supply side and the full bobbin is wound. So that it passes through the bobbin pan on the empty bobbin side, and the bobbin pan is provided with a spring-loaded claw that chucks the above-mentioned passing wire rod, and after the wire rod is chucked by the claw and the saucer by the force of this spring, By cutting the part closer to the full bobbin from the part where the wire rod is chucked by the cutter, the full bobbin can be removed, and the bobbin tray on the empty bobbin side chucks the end of the wire to be wound. is there.

As another conventional technique, for example, as disclosed in Japanese Examined Patent Publication No. 1-24708, when the winding start end of the wire is held by a winding cylinder (bobbin), the wire is wound around the inner circumference of the winding cylinder. A mechanism is provided to guide the winding start end of the wire through the hole, and to bend the guided wire rod end on the inner circumference of the winding drum, and hold the bent wire rod end around the wire rod insertion hole at the inner circumference of the bobbin. Alternatively, as disclosed in Japanese Patent Laid-Open No. 2-2780-2, there is a technique in which a wire rod end is held between a stopper flange of a bobbin shaft and a flange on one side of the bobbin to lock the wire rod end.

[0005]

[Problems to be solved by the device]

 Among the above-mentioned conventional techniques, the one described in the first conventional example, that is, the method in which the bobbin tray is provided with the claws for chucking the wire rod ends, when two or more (multi-wire) wire rods are simultaneously wound on the same bobbin. However, the following problems sometimes occurred.

That is, when two or more wire rod ends are chucked between the claw and the bobbin tray, if any of the wire rods is bent, the claw is lifted up, and the remaining wire rod ends are chucked. In some cases, the wire could be easily pulled out and the wire could not be cut or wound.

The present invention has been made in view of the above points, and an object of the present invention is to prevent a wire rod end from being unintentionally pulled out even when the wire rod end is chucked by a hook provided on a bobbin tray. It is to provide a winding and winding machine.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is basically a multi-winding winder in which a bobbin is placed on a rotating bobbin tray so that two or more wire rods can be simultaneously wound on the same bobbin. It is proposed that the saucer be provided with a claw for chucking the wire rod end and a jig for bending the wire rod end to engage with the hook.

Further, as an optimum specific example thereof, a plurality of bobbin pans which are rotated by a motor drive are arranged on a turntable, and a bobbin for winding a wire rod which is rotated together with the bobbin pans is placed on these bobbin pans, By rotating the bobbin, two or more wire rods are sequentially wound onto the same bobbin at the same time, and when the winding of the wire rod of one bobbin is completed, the turntable rotates to complete the winding of the wire rod and the winding of the wire rod. In the winder of the type that is to be repositioned with an empty bobbin, a stand roll that applies tension to the wire rod and guides the wire rod at a position between the bobbins is provided on the turn table. A cutter for cutting the wire rods is arranged around each bobbin, while each of the bobbin trays has a claw for chucking the wire rod on the inside and a core wire on the outside. A jig for terminal bending is provided, and when the turntable is rotated when winding and taking over the wire from the full bobbin to the empty bobbin, the wire provided between the bobbin and the claw provided on the bobbin tray on the empty bobbin side. The jig provided on the empty bobbin side bobbin tray is bent by pressing the wire rod, and the cutter cuts the wire rod at a position between the bobbins by rotating the empty bobbin side bobbin tray. We propose a multi-winding machine that is set up as follows.

[0010]

[Action]

 According to the above basic configuration, the end of the wire rod is checked by the claw provided on the bobbin tray, and the part protruding from the claw of the wire rod end is bent by the jig provided on the bobbin tray. When two or more wire rods are wound on the same bobbin at the same time, even if all the wire rods cannot be chucked due to bending of the wire rods, etc., the bent portion of the wire rod end is locked to the pawls. This prevents the wire rod from pulling out, enabling multiple windings.

The means of the above specific optimum example will be described in Examples.

[0012]

【Example】

 An embodiment of the present invention will be described with reference to the drawings.

FIG. 1A is a top view of a multiple winding and winding machine according to an embodiment of the present invention, and FIG. 1B is a front view thereof.

In these figures, 1 is a turntable, and a plurality of (two in this case) bobbin trays 6A, 6B which are rotated by a motor drive are arranged on the turntable 1 at 180 ° intervals in the circumferential direction, The bobbin 2A, 2B for winding the wire rod, which rotates together with the bobbin pan 6A, 6B, is placed on these bobbin pans 6A, 6B. By rotating the bobbin, two or more wire rods W are simultaneously wound on the same bobbin at the same time, and when the wire rod winding of one bobbin (for example, bobbin 2A) is completed, the turntable 1 is rotated to complete the wire rod winding. The full bobbin 2A and its receiving tray 6A are replaced with the empty bobbin 2B and its receiving tray 6B for winding the wire rod.

On the turntable 1, two stand rolls 8A and 8B are arranged on a line orthogonal to a line connecting the centers of the bobbin trays 6A and 6B. Of the stand rolls 8A and 8B, the roll 8A applies tension to the wire W at a position between the bobbins 2A and 2B when the bobbin 2A and the tray 6A are in the wire winding position as shown in FIG. If the turntable 1 rotates 180 degrees counterclockwise from the state shown in FIG. 1 and the bobbins and bobbin pans are repositioned, the position of the bobbin 2B, 2A between the bobbins 2B, 2A is guided. Is set so that tension is applied to the wire W to guide the wire W in traveling.

On the other hand, each bobbin tray 6A, 6B is provided with a claw 4 for chucking the wire W inside and a jig (guide) 5 for bending the core wire end outside.

In the above structure, when the wire W is wound up, it is carried out at a certain position of the bobbin receiving tray 6A in FIG. Further, when winding, the wire rod end is chucked on the claw 4 on the bobbin tray 6A side, but the wire rod W stands between the bobbins 2A and 2B and tension is applied via the roll 8A. It is hung up and laid over and led to the wire supply side.

When the winding of the wire on the bobbin 2A is completed, the turntable 1 rotates 180 degrees, the positions of the full bobbin 2A and the empty bobbin 2B are switched, and the winding of the wire on the bobbin 2B is performed as follows. To be taken.

When the turntable 1 is rotated (when winding and taking over the wire to the empty bobbin), the wire W comes into contact with the body diameter on the empty bobbin 2B side from the full bobbin 2A through the stand roll 8A, and the wire W is bobbin. When it goes down along the 2B body diameter, the wire W is chucked by the claw 4 provided on the receiving tray 6B on the bobbin 2B side, and at the same time, the wire W comes into contact with the jig 5 and is bent. Then, when the bobbin tray 6B is rotated relative to the cutter 7B and the vertical roll 8A by a certain amount, the wire W is pushed by the jig 5 and hits the cutter 7B to cut the wire W at a position between the bobbins 2A and 2B. It

When the turntable 1 is rotated 180 degrees as described above after cutting the wire rod, the positions of the empty bobbin 2B and the full bobbin 2A are switched, and at this time, the vertical roll 8B applies tension to the wire rod W. After that, the wire is wound around the empty bobbin 2B by rotating the bobbin.

It should be noted that two claws 4 and jigs 5 are attached to each bobbin tray so that the wire W is not chucked.

According to this embodiment, at the time of switching bobbins, the ends of two or more wire rods W are automatically chucked to the bobbin on the winding side via the claw 4. Even if the wire material at the chuck part is bent or irregular and the claw 4 is lifted, the wire material terminal part that is automatically bent by the jig 5 is locked to the claw 5. The wire is prevented from being accidentally pulled out from the chuck, ensuring a reliable winding of multiple wires.

Further, since a simple structure in which a claw for wire rod chuck and a guide-shaped wire rod bending jig are provided together on the saucer can be adopted, such a wire rod pull-out prevention mechanism can be manufactured at low cost. Further, since the wire does not come out, workability is improved.

[0024]

[Effect of device]

 According to the present invention, a claw for chucking a wire rod end is provided with a jig for bending the wire rod end so that the wire rod end can be locked to the claw so that two or more wire rods (multi-wires) can be wound. Even if the wire floats, it is possible to prevent the wire from coming off and reliably wind multiple wires.
