Description

Detailed Description of the Invention

2. Description of the Related Art Conventionally, in the manufacture of a capacitor element, for example, as shown in FIG. 1, a hanging scroll 1 is loaded with a metal foil film winding material 21 and a hanging scroll 2 is loaded with a separator film material winding 22. After being loaded, the condenser element 7 is guided to the aligning roller 4 through the guide roller 3 and wound around the winding shaft 6 of the rotor 5 to form the condenser element 7.
Thus, in such a process, the steps from the winding of the material loaded on the hanging shaft to the winding of the winding shaft 6 of the rotor 5 until the element 7 is manufactured are automatically controlled and operated. After the material winding material loaded on the hanging shaft is unwound toward the winding shaft and the core of the hanging shaft is emptied, a new material winding material is charged and supplied. The connection between the end of the unrolled material and the tip of new material is also made manually. During that time, operations must be paused, which is extremely time consuming.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and to automatically supply and load a new material winding material to automate the whole process, unmanned and highly accurate. An object of the present invention is to provide a continuous automatic winding device for a condenser film capable of operating at high speed.

[0004]

As a result of earnest research for achieving the object, the inventor of the present application emptied the work by interposing a material exchange means between the winder body and the material winding stocker. The idea is that a new winding material can be automatically loaded on the hanging shaft. From the arm that has chucks at both ends between the hanging shaft of the winder and the stocker of the material winding and rotates around the center as a fulcrum. A continuous film for condensers, characterized in that it is provided with a material exchanging means, and a connecting means is provided between the hanging shaft and the first guide roller, the connecting means comprising a clamper, a pressing roller, and a material film moving roller. Invented an automatic winding device.

The continuous automatic winding device for a condenser film of the present invention will be specifically described with reference to the drawings. As shown in FIG. 2, the continuous automatic winding device of the present invention has chucks at both ends between the hanging shafts 1 and 2 of the winder body 100 and the stocker 8 of the material winding material, and an arm which rotates about the center as a fulcrum. 3, the material exchanging means 9 comprises a chuck 11 for grasping an empty core left after winding on the hanging shaft and a new material at both ends, as shown in FIG. It has a chuck 12 for grasping the axis of the wound material 21 or 22 from the inside, and is composed of an arm 10 that rotates about a center 13 as a fulcrum, and operates as shown in FIG. 4, for example.

FIG. 4-1 shows a mode in which the winding operation is completed and the arm 10 is rotated 90 degrees in the direction of →. FIG. 4-2 shows that the material exchanging means 9 moves toward the hanging shaft and the material winding, the chuck 11 of the arm 10 is fitted to the empty core of the hanging shaft 1, and the chuck 12 is loaded with a new material winding on the stocker 8. A mode in which the material exchanging means 9 moves to the original position after fitting to the axis of the rotating article is shown. FIG. 4-3 shows a mode in which the arm 10 further rotates 90 degrees in the → direction, the chuck 11 discards the empty core, and then the arm 10 further rotates 90 degrees in the → direction. FIG. 4-4 shows a mode in which the material exchanging means 9 moves toward the hanging shaft and the material winding to load the material winding on the hanging shaft 1. FIG. 4-5 shows a state in which the material winding means 9 has been loaded and the material exchanging means 9 has returned to the state shown in FIG. 4-1.

In order to continue the winding in the continuous automatic winding device of the present invention, at the time when the material winding of the hanging shaft is fed to the aligning roller via the guide roller and is near the end, The section must be connected to the tip of the next roll. Therefore, the hanging shaft of the winder body and the first
Connection means are provided between the guide roller and the guide roller. The configuration and operating mode of the connecting means will be described with reference to FIG.

The connecting means comprises a clamper 14, a pressing roller 15 and a film moving roller 16 and operates as shown in FIG. FIG. 5-1 shows hanging shafts 1 and 2.
It shows a state in which the material windings 21 and 22 which have just been hung on are wound up via the guide roller 3, and the clamper 14 is not activated at this point. FIG. 5-2 shows a mode in which the film moving roller 16 moves in the direction of → as the material windings 21 and 22 are being wound, and the clamper 14 is not operating at this time. FIG. 5-3 shows a mode in which the movement of the film is stopped and the film moving roller 16 contacts the material film of the wound material and moves it in the direction of →, and the clamper 14 is still operating at this time. Absent. Figure 5-4 shows the film moving roller 1
6 shows a state in which 6 rotates in the direction of → to pass the material film of the wound material between the clamping members of the clamper 14. 5-5 illustrate how the clamper 14 clamps the roll material film passed by the transfer roller 16 between clamping members. 5-6 show the manner in which the material film of the wound material is cut by the cutter 17 attached to the clamper 14. At this point, a new material winding material is loaded on the hanging shafts 1 and 2 by the material exchanging means. 5-7 and 5-8, the pressing roller 15 moves in the direction of → to push the material film of the wound material toward the newly wound material film loaded on the hanging shafts 1 and 2, and the end thereof. Shows the manner in which is connected to the material film of the newly loaded roll. FIGS. 5-9 show the manner in which a new material roll, whose tip is connected to the end of the material film of the previous roll, is about to be taken up. FIG. 5-10 shows a state in which the state of FIG.

The stocker of the material winding material 8 stores a plurality of material winding materials. When the leading material winding material is chucked by the chucks 11 and 12 of the material exchanging means 9, the next material winding material is sent out in sequence. It is configured to be located at the beginning position.

Therefore, in the continuous automatic winding device of the present invention, the material wound in the material stocker is fed out,
The movement of the material exchanging means, the fitting of the chuck and the material winding and the rotation of the arm, the operation of each member of the connecting means, the rotation of the rotor, the formation of the element and the members associated therewith are all automatically controlled by the automatic control means. Controlled operation, the steps from the material winding to the element formation can be continuously operated for a long time unattended except for the batch supply of the material to the stocker.
