Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding machine used for assembling a transformer, and more particularly, to a winding machine capable of handling a large diameter disk-shaped core to a small diameter cylindrical core.

[0002]

2. Description of the Related Art At present, in transformers mainly used for transformers, circuit breakers and the like, devices having higher performance and higher reliability have been remarkably popularized. Therefore, in assembling the transformer, it is indispensable to wind the copper wire uniformly around the iron core at a constant tension and a constant interval. On the other hand, the iron core itself has a wide range of sizes and shapes from a small-diameter cylindrical shape to a large-diameter disk shape according to the specifications of the transformer. In this case, it is not preferable to use a different winding machine according to the size and shape of the iron core because the use efficiency of the winding machine is significantly reduced and the cost is significantly increased. Therefore, in the transformer assembling, a winding machine capable of always uniformly winding a copper wire on iron cores of various sizes and shapes is indispensable.

Conventionally, a large winding machine having a large diameter winding ring as shown in FIG. 6 has been mainly used as a winding machine capable of coping with iron cores having various dimensions and shapes. As shown in FIG. 6, the winding machine includes a winding ring 61 for previously winding a required amount of copper wire, and an iron core rotating mechanism 62 arranged on a surface perpendicular to the ring rotation surface and rotating the iron core 6. And a storage drum 51 for winding a copper wire around the winding ring 61. And the winding ring 61
The copper wire is wound around the iron core 6 by rotating the iron wire 6 and rotating the iron core 6 by the iron core rotating mechanism 62 to gradually shift the winding position of the copper wire on the iron core 6. It is designed to be wound evenly.

[0004]

As described above, it is important to uniformly wind a copper wire on a core with a constant tension in the transformer assembling process. Although a copper wire can be uniformly wound around a large-diameter disc-shaped iron core with a constant tension, it is difficult to wind a copper wire uniformly around a small-diameter cylindrical iron core with a constant tension. Hereinafter, this problem will be described.

First, in a winding machine having a large-diameter winding ring 61 as shown in FIG. 6, due to its structure, the winding section of the core 6 is cut near the rotation center axis of the winding ring 61. An area center must be present. Regarding this condition, in the case of a large-diameter disc-shaped iron core, it is relatively easy to overlap the center of the cross-sectional area of the iron core 6 on the rotation center axis of the winding ring 61 having a large diameter. However, when the diameter of the winding ring 61 is larger than the diameter of the iron core 6 in the small-diameter iron core, it is impossible to overlap the center of the sectional area of the iron core 6 near the rotation center axis of the winding ring 61. is there. In this case, the copper wire on the circumference of the winding ring 61 repeatedly expands and contracts because the distance to the iron core 6 changes, and it is impossible to wind the copper wire uniformly at a constant tension. Further, the change in tension generated in the copper wire due to the curvature of the winding ring 61 is negligible in the case of a disc-shaped iron core, but in the case of a cylindrical core, the change in tension between the iron core 6 and the winding ring 61 is small. Due to the distance relationship with the circumference, the influence is not so small, and it is impossible to wind the copper wire uniformly at a constant tension. From the above, the winding machine having the large-diameter winding ring 61 as shown in FIG.
It can be seen that the method is effective only for iron cores having a diameter larger than 1, and it is difficult to wind the copper wire uniformly around the other iron cores with a constant tension.

Further, the winding machine as shown in FIG. 6 has a problem that the size of the device is increased as a result of having the winding ring 61 having a relatively large diameter. FIG.
In the conventional winding machine as shown in the above, it is only possible to wind the copper wire, and for the insulation sheet winding, which is one of the assembly processes, it has to be done by human work,
There are also problems such as an increase in work setup load and a decrease in work efficiency.

[0007] The present invention has been proposed to solve the above-mentioned problems of the prior art.

At this time, the iron core is rotated at a constant speed by the table. Further, by adjusting the rail portion, the bobbin portion can be caused to travel along an appropriate route according to the size and shape of the iron core. As a result, not only can a uniform copper wire be wound with a constant tension, but also a uniform insulating sheet can be wound with a constant tension. Furthermore, the rail section, whose vertical and horizontal dimensions can be adjusted according to the dimensions and shape of the iron core, and the bobbin section that runs on this rail section, can be configured compactly and can be operated with only the minimum necessary space. Therefore, the whole winding machine can be reduced in size and space.

[0014] In the above-mentioned second and fifth aspects of the present invention, the bobbin for copper wire (first bobbin) and the bobbin for insulating sheet (second bobbin) are synchronized during the winding operation. By self-running, it is possible to simultaneously wind a copper wire and an insulating sheet. Therefore, the copper wire winding and the insulating sheet winding can be performed simultaneously with the iron core position fixed, so that the setup work can be improved and the work efficiency can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, typical embodiments to which the above-described winding machine of the present invention and a winding forming method using the same are applied will be specifically described with reference to the drawings. I do.

[1. Configuration of Winding Machine] FIG. 1 is a front view showing one embodiment of a winding machine according to the present invention. As shown in FIG. 1, the winding machine includes a bobbin unit 1, a rail unit 2, a chain unit 3, a table 4, and a wire storage unit 5. The bobbin unit 1 runs on the rail unit 2 by itself. Thereby, a copper wire and an insulating sheet are wound around the iron core 6 arranged on the table 4.

As shown in FIG. 3, the rail portion 2 comprises L-shaped iron core side rails 21 and 22 and main body side rails 2 which are main components.
3, 24, and a length adjusting rail 25 for adjusting the dimension between the rails 21 to 24 to match the dimension and shape of the iron core 6. Here, the respective end faces of the iron core side rails 21 and 22 and the main body side rails 23 and 24 are overlapped on the length adjusting rail 25, and the rails 21 to 24 slide independently up, down, left and right. I can do it.

By fitting the bobbin 1 into the support guide 53, the copper wire or the insulating sheet 7 on the wire storage drum 51 can be wound with a certain tension via the powder brake 52. I have.

[2. Winding Forming Procedure] Next, a procedure for forming a winding by using the above-described winding machine will be described. As a setup operation, first, the core 6 is set on the table 4 (iron core arrangement step). Next, the dimensions of the rail portion 2 are adjusted in accordance with the dimensions and shape of the iron core 6, thereby adjusting the dimensions of the chain portion 3 (rail portion adjusting step). That is, the core side rails 21 and 22 and the main body side rails 23 and 24 of the rail portion 2 are
It is moved on the length adjustment rail 25. Then, along with the adjustment of the rail portion 2, each portion 3a, 3
The copper wire winding running chain 31, the copper wire winding tension chain 32, the insulating sheet running chain 33, and the insulating sheet tension chain 34 also move. At the time of such adjustment, the bobbin part 1 is mounted on the rail part 2 (bobbin mounting step). That is, the bobbin portion 1 on which the necessary amount of copper wire is wound in advance is inserted into the side of the rail portion 2 having the copper wire chains 31 and 32, and the bobbin portion 1 on which the necessary amount of insulating sheet is wound in advance is used. The rails 2 are inserted into the side having the chains 33 and 34 for insulating sheets.

After the above-described setup work, the rail 2
The copper wire winding and the insulating sheet winding are simultaneously performed by self-propelling the two bobbin portions 1 (winding step). That is, by controlling the two bobbin portions 1 around which the copper wire and the insulating sheet are respectively wound by the copper wire / insulating sheet chains 31 to 34, the copper wire or the insulating sheet 7 is formed.
By appropriately adjusting the tension of the steel sheet and relatively running on the rail portion 2 and rotating the table 4 to rotate the iron core 6, the copper wire winding and the insulating sheet winding can be performed simultaneously. In this winding step, the bending can be eliminated by appropriately adjusting the tension of the copper wire or the insulating sheet 7 by the tension chains 32 and 34 of the chain portion 3. That is, the bobbin part 1 is
When passing through the upper and lower surfaces of the copper wire or the insulating sheet 7 due to the distance between the iron core 6 and the bobbin portion 1,
The tension chain 32 for copper wire winding and the tension chain 34 for the insulating sheet are connected to the respective running chains 3.
The problem can be solved by performing reverse rotation with respect to 1, 33.

In the above winding process,
A copper wire or an insulating sheet 7 can be wound around another bobbin portion 1. That is, the bobbin 1 different from the two bobbins 1 for winding the copper wire and the insulating sheet described above is inserted into the support guide 53 and the tension sprocket 12 of the bobbin 1 is engaged with the chain 3. Accordingly, the copper wire or the insulating sheet 7 of the wire storage drum 51 can be wound around the bobbin 1 via the powder brake 52. In this case, the driven chain part 3
With the powder brake 52, the copper wire or the insulating sheet 7 can be wound around the bobbin 1 with a constant tension.

[3. Operation / Effect] According to the above-described winding machine and the winding forming procedure using the same, the following operation / effect can be obtained.
The effect is obtained. First, the sprockets 11 and 12 attached to the bobbin portion 1 mesh with the running and tension adjusting chains 31 to 34 so that the tension of the copper wire or the insulating sheet 7 in the bobbin portion 1 is appropriately adjusted. Since it can be adjusted, it is possible to perform uniform winding with a constant tension regardless of the size and shape of the iron core 6. Thus, even in the case of a small-diameter cylindrical iron core 6 which cannot be wound uniformly with a constant tension in the past, it is possible to wind a copper wire or an insulating sheet, thereby improving product quality and reducing wasted time. .

In particular, the winding of the insulating sheet, which has conventionally been performed manually, can be automated by the self-propelled operation of the bobbin 1, so that the setup operation can be simplified and the operation efficiency can be improved. Moreover, it is possible to wind the copper wire and the insulating sheet at the same time, and to wind both of them with a constant tension by the chain portion 3.
Setup work can be made easier, work efficiency can be further improved, and product quality can be further improved.

Further, in the winding step, at the same time as winding the copper wire and the insulating sheet around the iron core 6, the copper wire or the insulating sheet 7 is wound around another bobbin portion 1 to prepare for the next winding formation. . This also improves the working efficiency and reduces the dead time. Further, since a new power source is not required from the wire storage drum 51, simplification of the entire apparatus can be realized, leading to a reduction in manufacturing cost.

The rail 2 which can be adjusted vertically and horizontally according to the size and shape of the iron core, and the bobbin 1 which runs on the rail 2 can be compactly constructed and can be operated with only a minimum necessary space. Since it is possible, it is possible to reduce the size and space of the entire winding machine as compared with a conventional winding machine in which the winding ring 61 is rotated. In particular, the self-propelled bobbin unit 1 is much smaller than the winding ring 61, so that the required power is minimal, and this also leads to a reduction in manufacturing costs.

[4. Other Embodiments] The present invention
The present invention is not limited to the above embodiment, and various other embodiments can be implemented. That is, specific configurations and dimensions and shapes of the bobbin, rail, chain, table, and wire storage section can be appropriately selected. Further, in the above-described embodiment, the procedure of winding the copper wire or the insulating sheet around another bobbin portion while forming the winding by using the traveling chain has been described. It is also possible to wind the copper wire or the insulating sheet around the wire separately from the winding without using the traveling chain. Further, in the above-described embodiment, the procedure of simultaneously performing the copper wire winding and the insulating sheet winding has been described. However, depending on the case, the copper wire winding and the insulating sheet winding may be performed separately.

[0033]

As described above, according to the present invention,
The bobbin around which the required amount of winding material has been wound is run on a rail that can be moved according to the dimensions and shape of the iron core, and the chain is used to run the bobbin and adjust the tension of the winding material. By doing so, copper wire can be wound uniformly at constant tension on iron cores of various dimensions and shapes, and insulating sheets can be wound, making it possible to reduce the size and space, improve product quality, and improve work efficiency. A winding machine capable of reducing costs can be provided.
