The side regulating member 43 is composed of a guide 43a fixed so that the entry side of the seed plate 12 is slightly opened, and a pusher 43b provided so as to be able to approach and separate from the guide. The stopper 42 moves up and down a predetermined length. The feed claw 45 is movable in the long groove as shown. To the right of the cradle 41, that is, in the
Are further provided at predetermined intervals in the longitudinal direction of the seed plate 12, and are rotatable by a motor (not shown). The interval between the rotary blades 47 corresponds to the horizontal dimension of the ribbon. In FIG.
Reference numeral 48 denotes a guide provided for smoothly feeding the positioned seed plate 12 to the rotary blade 47 by the feed claw 45.

The operation of this embodiment will be described. First, a seed plate 12 stacked on a container 11 as shown in FIGS.
Is sucked by the vacuum pads 17 and 18 lowered by the cylinders 20 and 21 and lifted to a predetermined position. When the seed plate 12 is lifted to a predetermined position,
The gripper 22 moves forward by the detection signal of a detection member (not shown) for detecting this, and clamps the rear end of the seed plate 12. When the rear end of the seed plate 12 is gripped by the gripper 22,
The suction of the vacuum pad 17 is released, and the seed plate 12 is held by the vacuum pad 18 at the front end and the gripper 22 at the rear end. In this state, the support piece 26 and the support piece 29 advance along the guide rails 28 and 30, respectively, so that the front half of the seed plate 12 is positioned on the receiving portion 36 of the receiving base 35.
Then, the suction of the vacuum pad 18 is released, and the first half of the seed plate 12 falls on the upper surface of the receiving portion 36 and is received. After being received, the gripper 22 sandwiching the rear end advances further, so that the front end of the seed plate 12 reaches near the cutter 40 of the first cutting device 32. Thereafter, the cutter 40 moves upward to pass through the front end of the seed plate 12, and then moves downward to cut the front end 12a (a in FIG. 4). At the time of this cutting, the falling portion 37a of the transport roller portion 37 falls down, and the mixing prevention guide 39
Is turned upward, and the cut front end 12a is not sent to the second cutting device 33, and is reliably turned as a chip.
It is dropped from the opening that was opened by the fall of 37a (FIG. 3).

After the cutting, the falling portion 37a of the transport roller 37 returns to the state before the falling, and the next cutting is performed.
This cutting is performed twice at a predetermined feeding position (a position where the length of the ribbon becomes the vertical dimension from the position of A in FIG. 4) so that the length becomes a preset length (FIGS. 4B and C). Then, the central portion 12b of the seed plate 12 cut into two pieces is sequentially slid down the transport roller portion 37 one by one, sent to the second cutting device 33, and placed on the upper surface of the receiving table 41. Become. The rear end 12c of the seed plate 12 sandwiched by the grippers 22 at the time of the second cutting at the position C in FIG. 4 is turned into chips like the front end 12a, and after the falling portion 37a is again in the falling state. It is fed by the gripper 22 and dropped from the opening. As described above, since one seed plate 12 becomes two parts 12b, this cutting is
It is called a section break.

Next, the seed plate 12 cut into two sections and placed on the upper surface of the pedestal 41 of the second cutting device 33 is provided with a stopper 42 on the pedestal.
The front end is brought into contact with the
Pusher 43b approaches the guide 43a side to position both sides of the cut central portion 12b of the seed plate 12. Thereafter, the stopper 42 is released and moves upward, and the feed claw 45 pushes the central portion 12b into the rotary blade 47. The central portion 12b of the seed plate 12 sent to the rotary blade 47 is cut into a plurality of pieces by the rotary blade 47 in the same direction as the traveling direction (d in FIG. 4). Also at this time, both ends 12e in the traveling direction of the central portion 12b are cut off as chips. Since the central portion 12b of the seed plate 12 cut into two strips as described above becomes further ten copper plates 12d, this cutting is referred to as ten strip cutting.

The copper plate 12d cut into 10 strips is overlapped and converged at one place by a convergence member (not shown), and after being converged, pushed into the container from the consolidation portion by a pusher (not shown) from above to be housed. Then, since the ribbon 1 of the cathode 4 is transported to the loading portion so as to be produced, the transport by the crane is waited. As a result, one cycle of the operation is completed, and the same operation will be repeated automatically thereafter.

The above operations are all automatically controlled by a sequencer (control device) (not shown). In this embodiment, the members that control the operation, such as the gripper 22, are merely examples, and other members having the same effect may be used.

[0016]

According to the first to fourth aspects of the present invention, since the ribbon of the copper electrolytic cathode is formed,
It can be performed automatically without any human intervention. In particular, it is possible to cut off necessary seed plates by cutting off the front and rear ends of the seed plates having irregular shapes, which are no longer needed, as scraps and discarding the waste copper. Further, the number of processed sheets can be greatly increased, and workability can be significantly improved. Furthermore, since the operation is all automatic and there is no need to rely on human labor as in the prior art, safety is significantly improved. Furthermore, in addition to good quality and low labor cost, the seed plate can be cut by a first cutting device and a second cutting device arranged in series along the transport direction. Therefore, there is an excellent effect that the space is compact.
