Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electrolytic capacitor element winding device that continuously winds an electrolytic capacitor element.

[Conventional technology]

An electrolytic capacitor has an electrolytic capacitor element sealed in an outer case, and external terminals for connecting the electrolytic capacitor element and an external circuit are drawn out from the outer case.

As shown in FIG. 8A, the electrolytic capacitor element 2 is formed by winding the anode foil 4 and the cathode foil 6 in a spiral shape with separators 8 and 10 interposed between the anode foil 4 and the cathode foil 6. Tabs 12 and 14, which serve as external terminals, are connected to the cathode foil 6.

The manufacturing process of this electrolytic capacitor element 2 consists of a processing process for the anode foil 4 and the cathode foil 6, and a winding process. Chemical conversion treatment, cutting treatment, connection treatment of tabs 12 and 14 to anode foil 4 and cathode foil 6, etc. are performed. Therefore,
In the winding process, the separators 8 and 10 are inserted between the anode foil 4 and the cathode foil 6 to which the tabs 12 and 14 are connected, and are rotated around the winding shaft to complete the electrolytic capacitor element 2. Then, as shown in FIG. 8B, a holding tape 16 is attached to the wound electrolytic capacitor element 2 as a final step of the winding process to prevent loosening of the winding.

[Problem to be solved by the invention]

Conventionally, such winding processing of electrolytic capacitor elements has had a great effect on reducing manufacturing costs, and has been automated.

By the way, the processing of one electrolytic capacitor element 2 includes supplying the anode foil 4, cathode foil 6, and separators 8, 10 to the winding shaft, rotating and stopping the winding shaft,
Processes such as attaching the holding tape 16 to the wound electrolytic capacitor element 2 and removing the electrolytic capacitor element 2 are performed, and even if the rotation speed of the winding shaft is increased, other processing takes time, so production It is impossible to increase efficiency.

In addition, if multiple winding devices are installed together, the amount of winding can be increased in proportion to one winding device, but the price of the winding device will affect the production cost, etc. Experience tells us that an increase in production efficiency does not necessarily lead to an increase in production efficiency.

Therefore, a first object of the present invention is to provide a winding device for an electrolytic capacitor element that uses a plurality of winding shafts to improve winding efficiency.

Set to position. The rotational force is transmitted from the first winding shaft drive mechanism to the first winding shaft, and the rotational force is transmitted from the second winding shaft drive mechanism to the second winding shaft. The second winding shaft is given an independent rotational state. The drive timings of the first and second winding shaft tables and the driving timings of the first and second winding shafts are controlled by the timing control means, and an optimum winding shaft state is set.

Therefore, in this winding device, such a winding process of the electrolytic capacitor element is performed for each of the first and second winding shafts in accordance with the rotation of the first and second winding shaft tables. For example, three winding shafts are installed on one winding shaft table, and the first and second winding shafts have a total of six winding shafts, and each winding shaft on the first and second winding shaft tables is alternately selected and wound. If the process is repeated, six electrolytic capacitor elements will be manufactured in one rotation of the first and second winding tables. Therefore,
In this winding device, the first
When the winding shaft is performing winding processing, the second winding shaft on the second winding shaft table performs work other than winding processing, so winding processing is performed between other work. Therefore, the winding process can be performed almost continuously, and a manufacturing speed determined by the rotational speed of the first and second winding shafts and the number of winding layers of the electrolytic capacitor element can be realized, and manufacturing efficiency can be improved.

(Claim 2) Furthermore, in the electrolytic capacitor element winding device of the present invention, the first and second winding shaft drive mechanisms include:
A planetary gear mechanism is configured by the first and second gears. That is, the rotational force applied from the drive source is transmitted to the first gear of the rotating cylinder to rotate the rotating cylinder, and the rotational force is transmitted to the third gear of the first and second winding shafts through the second gear. transmitted to the gears.
