Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for manufacturing an electrolytic capacitor element, and more particularly, a plurality of cam mechanisms arranged on one main shaft to operate a large number of devices at the same timing. All the steps of winding the electrolytic capacitor element are completed by one rotation of the above, and the rotation speed of the main shaft is set to a high speed only during the period other than winding the insulating paper and the aluminum foil for a series of operations other than winding. By shortening the time of, the time that can be used for winding is extended, and during the winding period, each device is stopped and the device can be operated even with a large electrolytic capacitor element that winds the insulating paper and aluminum foil. However, the present invention relates to an epoch-making electrolytic capacitor element manufacturing method and apparatus capable of winding the electrolytic capacitor element in a shorter time.

[0002]

2. Description of the Related Art A conventional electrolytic capacitor element manufacturing apparatus includes an extracting device for grasping one end of an insulating paper and drawing it out from an insulating paper supply port, and an aluminum foil conveying device for supplying one end of an aluminum foil to a winding shaft. , A winding shaft that captures the central part of the insulating paper with a groove and winds it together with the aluminum foil, an aluminum foil cutting device that cuts the aluminum foil, an insulating paper cutting device that cuts the insulating paper, and a winding of the insulating paper and the aluminum foil. As an example of a winding end terminating device for terminating the end end so as not to loosen, an adhesive coating device for applying an adhesive to the wound insulating paper is provided on a spindle that rotates at a constant rotation speed. All the above-mentioned devices are sequentially operated in one cycle in which the main shaft is rotated once it is connected to the cam mechanism to complete all the steps.

Therefore, the time available for winding the insulating paper and the aluminum foil is only a limited time in one cycle, and only an electrolytic capacitor element having a size that can be wound in the limited time is manufactured. It had the drawback of not being able to do it.

Specifically, in FIG. 10, assuming that the main shaft rotates at a constant rotation speed N ₁ and the time for one cycle is 1.2 seconds, the operation time O ₁ of the series of devices is 0.9 seconds. Therefore, the winding time W ₁ that can be used for winding the insulating paper and the aluminum foil can be used only for the remaining 0.3 seconds, and only a small electrolytic capacitor element can be manufactured.

The limit of the electrolytic capacitor element that can be wound in 0.3 seconds is, for example, an electrolytic capacitor element having a diameter of about 4 to 6.3 mm, and when manufacturing a larger electrolytic capacitor element, insulation is required. After the first half operation of supplying paper and aluminum foil to the winding shaft is completed, the electromagnetic clutch brake is activated to stop the series of operations of the electrolytic capacitor element manufacturing device, and only the winding shaft is rotated to insulate the insulating paper. Also, after winding the aluminum foil and winding it for a specified length, the electrolytic capacitor element manufacturing device is operated again to perform the latter half of the operation to secure the winding time and manufacture the electrolytic capacitor element. However, it takes a lot of time to stop and restart the electrolytic capacitor element manufacturing equipment, which is not directly related to the production of the electrolytic capacitor element, and it takes 1 cycle. It has a drawback that it is impossible to improve the production efficiency is increased.

[0006]

A cutting device, an insulating paper cutting device, and a winding end terminating device are respectively connected to a cam mechanism arranged on a spindle, and the cam mechanism sequentially operates, and the rotation speed of the spindle is set to a predetermined value by controlling the insulating paper and the aluminum foil. By shortening the time for a series of operations other than winding by increasing the speed only during the period other than winding the length, the time available for winding the insulating paper and aluminum foil is increased, making conventional manufacturing difficult. It was to enable the production of a large electrolytic capacitor element without stopping the rotation of the main shaft of the device during the winding of the element. The production efficiency of the capacitors elements is to greatly improve.

Another object is to make it possible to change the rotation speed steplessly by using an inverter-controlled AC motor as the drive device for rotating the main shaft, and also by this. It is possible to set the rotation speed of the AC motor to the optimum rotation speed according to the size of the electrolytic capacitor element, and the manufacturing apparatus of the electrolytic capacitor element does not substantially contribute to the manufacturing of the electrolytic capacitor element. The purpose is to eliminate the time and efficiently manufacture an electrolytic capacitor element.
