First, the semi-finished product 14 conveyed by the carry-in conveyor 51 from an upstream process (not shown) is aligned by the guide rail 52 in front of the take-in rotary wheel 27.

In this state, when the starting condition of the entire apparatus is satisfied, the respective parts are rotationally driven in synchronization. At the start of this operation, first,
The semi-finished product 14 is scraped off from the leading end of the guide rail 52 by the notch 27a of the rotary table 25, and the position Pos. 1 and the position Pos. 1
Is transferred and sucked and held by the work chuck 33 of the holding device 26 located at the position.

The semi-finished product 14 held by the work chuck 33 is moved to the position Po by the rotation of the rotary table 25.
s. 2 moves in the circumferential direction. And semi-finished products 14
The rotation holding mechanism 34 starts to rise from the position where it comes out of the interference area of the take-in rotary wheel 27, and the work chuck is
The semi-finished product 14 held by 33 is fitted and held by a guide ring 41. When the holding of the semi-finished product 14 by the rotation holding mechanism 34 is completed, the work chuck 33 is driven backward by the cam 32 to be separated from the semi-finished product 14.

The rotation of the semi-finished product 14 is stopped by abutting on the hook 44 constituting the 43, and the positioning with respect to the semi-finished product 14 is completed.

In this state, as the semi-finished product 14 continues to move in the circumferential direction, the rotating roller 42 separates from the driving roller of the rotary driving mechanism 58. The work chuck 33 is a cam.
The semi-finished product 14 driven forward by the 32 and positioned is sucked and held again. Further, the hook 44 is separated from the semi-finished product 14 by the swinging lever 45 being swingably driven by the cam 31.

Accordingly, the work chuck 33 is driven backward by the advance / retreat mechanism 38 and is separated from the semi-finished product 14 only while the semi-finished product 14 is being rotationally driven by the rotary drive mechanism 58. During the period, the semi-finished product 14 is securely held by suction.

os. 4, the insertion head 49 of the insertion mechanism 47 provided corresponding to the holding device 26 is lowered, and the position Po is reached.
s. The insulating panel 13 supplied to 4 is sucked and held and rises.

Thereafter, the insertion mechanism holding the insulating panel 13
47 and holding device 26 holding semi-finished product 14 after positioning
Moves to a position outside the interference area of the supply rotary wheel 28, the position Pos. When moving up to 6, the insertion mechanism 47
The insertion head 49 of the semi-finished product 14 is lowered again
Insert the insulating plate 13 into the
And rises again to the upper limit position. That is, during the movement of the semi-finished product 14 in the circumferential direction, the insulating plate 13 is inserted into the predetermined position in the semi-finished product 14 by the insertion mechanism 47.

Thereafter, the semi-finished product 14 is moved to the position Pos. 6 to position Pos. 7, the rotation holding mechanism 34 is retracted downward by the upper and lower sliders 39 serving as the retracting mechanism.
For this reason, the semi-finished product 14 into which the insulating plate 13 is inserted is only sucked by the work chuck 33, and the position Pos. 7, the workpiece is scraped off from the work chuck 33 by the notch 29 a of the take-out rotary wheel 29.
Then, it is transferred to the guide rail 54 of the discharge conveyor 53 by the take-out rotary wheel 29, separated at the tip of the guide rail 54, and discharged by the discharge conveyor 53 to the next step (not shown).

Also, a series of operations of one holding device 26 provided on the rotary table 25 and an insertion mechanism 47 corresponding to the holding device 26 are shown. The holding device 26 and the insertion mechanism 47 corresponding to the holding device 26 sequentially perform the same operation. Therefore, the insulating plate 13 can be inserted into each of the eight semi-finished products 14 by rotating the turntable 25 once.

As described above, the semi-finished product 14 circulated from the upstream process is taken in by one driving source, and the positive electrode tab 12
A series of operations for positioning a, inserting and removing the insulating plate 13 can be continuously performed. In other words, the conventional transfer mechanism having a dedicated drive system, the positioning mechanism for the positive electrode tab, the cut-off and separation of the insulating plate, and the transfer mechanism can be eliminated, and the equipment can be reduced in size and simplified. In addition, a complicated control system is not required, and the equipment cost can be significantly reduced.

Therefore, a semi-finished product can be realized by a simple mechanism without providing a complicated mechanism and a control system as in the prior art.
Each process can be performed simply by moving 14 continuously, and high-speed production becomes possible. That is, since the semi-finished product is not intermittently moved unlike the conventional case, the operation time can be eliminated, and the productivity can be improved about three times as much as the conventional one by increasing the speed. In addition, since large-scale production can be performed with a small number of facilities, investment efficiency is improved by several steps as compared with the conventional case.
