DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for winding a capacitor element used for producing a piece-shaped capacitor element.

[0002]

2. Description of the Related Art The structure of a conventional capacitor element winding device will be described with reference to FIGS. The capacitor element winding device includes a composite rotating section 1 for winding a material 9 such as an electrode foil and a plastic film on a cylinder, and a spool shaft 27 for releasing and applying tension to a roll-shaped material 26.
It comprises a guide roller 25 for guiding the unraveled material 9. The composite rotating unit 1 includes a fixed frame 28 and a spatula 29. When the spatula 29 is pulled out, the capacitor element 24 becomes slack as shown in FIG.
4 can be removed.

[0003]

However, in the conventional winding operation of the capacitor element, FIG.
As shown in FIG.
9 was attached and detached. Because there are many winding elements,
It took a long time to attach and detach, and the burden on the worker's body was great. In view of the above, an object of the present invention is to automate the work of loosening a winding element without removing and attaching a spatula in a capacitor element winding operation, to reduce a burden on an operator, and to shorten a winding operation time. .

[0004]

In order to achieve the above-mentioned object, a composite rotary unit comprises two fixed frames and two movable frames fixed to a core shaft cylinder, and has a sliding mechanism interlocked with the movable frames. The movable frame is moved at a right angle to the core shaft cylinder by a sliding mechanism arranged on the core shaft cylinder using the fixed frame fixed to the core shaft cylinder as a guide, and the fixed frame is used as a stopper. Structure. By the sliding mechanism, the movable frame is moved in and out, so that the capacitor element is slackened and can be removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be specifically described below with reference to the drawings. First, as shown in FIG. 2, the composite rotating unit 1 has a rectangular core shaft cylinder 2 and operation plates 3a and 3b slidably inserted in a direction perpendicular to the core shaft cylinder 2; A tension spring 5 acting in a direction to bring the wedge-shaped plate 4 and the operation plate 3a closer to the operation plate 3b so as to be interlocked with the wedge-shaped plate 4; and for moving the wedge-shaped plate 4 in the axial direction of the core shaft cylinder 2. It is formed by air cylinders 6a, 6b and the like. The movable frame 7a includes the operation plates 3a, 3
c, the movable frame 7b is engaged with the operation plates 3b, 3d, and the fixed frames 8a, 8b are fixed to the core shaft cylinder 2 so that the material 9 is formed into a circular shape at the time of winding as shown in FIG. Are located. The main shaft 10 is rotatably disposed by a bearing 12 or the like in a housing 13 fixed to a gantry 11 shown in FIG. 1, and rotational force is transmitted via a coupling 15 and a drive source 14 for rotating the composite rotating unit 1. It is formed to be. Air holes 16a and 16b are formed in the main shaft 10 to supply air to the air cylinders 6a and 6b.
a, 6b. In order to constantly supply air to the rotating main shaft 10, the housing 13 is provided with a circumferential groove 18 on the inner surface, and the housing 13 is provided with a through hole 1.
9a and 19b are provided, and by operating the air source 21 with the solenoid valve 20, the air cylinders 6a and 6b are provided.
b can be driven. Therefore, when air is supplied in the direction in which the cylinder rods 22a, 22b come out by operating the electrode valve 20, the wedge 4 moves, and the operation plates 3a, 3b, 3c, 3d move outward, as shown in FIG. The movable frames 7a and 7b and the fixed frame 8a
8b is cylindrical and held in the state at the time of winding. Conversely, when air is fed in the direction in which the cylinder rods 22a and 22b return by operating the electrode valve 20 as shown in FIG. 3, the movable frames 7a and 7b enter inside by the spring 5 as shown in FIG. Reference numeral 27 in FIG. 6 denotes a removal rod for removing the capacitor element, and 24 denotes a capacitor element.
In order to manufacture the capacitor element 24 with the above-described configuration, first, the movable frames 7a and 7b are expanded in the outer peripheral direction so that the composite rotating portion 1 becomes cylindrical by operating the electromagnetic valve 20, and the material roll 26 9 is supplied and fixed to the fixing frame piece 8a with a fixing tool (not shown), and then the driving source 14 is driven to rotate the composite rotating unit 1 via the coupling 15 and the main shaft 10 to form a predetermined amount of cylindrical material. The material 13 is taken up, the capacitor element 24 is taken up, and the drive source 14 is stopped. Next, in order to remove the capacitor element 24 that has rolled up from the composite rotating section 1, the solenoid valve 20 is operated so that the movable frames 7a and 7b enter the inside, so that the capacitor element 24 has slack. As shown in FIG. 6, a removal rod 27 is inserted into a groove 28 provided in the fixed frame 8a, and is removed together with the capacitor element 24, thereby obtaining a shape as shown in FIG. As shown in FIG. 8, by removing the removal rod 27, a piece-shaped capacitor element 24 is completed. As mentioned above,
Just by operating the solenoid valve 20, the movable frame 7 of the
a, 7b can be taken in and out.

[0006]

According to the present invention, as described above, by moving the movable frame of the capacitor element winding device in and out by the power source, the capacitor element can be quickly slackened without removing the spatula. Thus, the burden on the operator can be reduced.
