A pair of storage grooves 4 and 5 for storing a plurality of thin plates 3 are formed by engraving in the longitudinal direction of the rotary drum 1. A plurality of thin plates 3 are stacked in the storage grooves 4 and 5 to be stored as a thin plate group.

On the other hand, an elevator 6 is provided, and a thin plate holding plate 7 is provided on the elevator 6. The thin plate holding plate 7 is inserted into either one of the storage grooves 4 and 5 and moves up and down along the storage grooves 4 and 5.

With such a structure, for example, a plurality of thin plates 3 are stored in the storage groove 5, and in this state, the thin plate holding plate 7 of the elevator 6 is arranged below the storage groove 5 and is in a standby state.

When the delivery of the thin plate 3 is started from this standby state, the elevator 6 raises the thin plate holding plate 7 at a speed corresponding to the delivery speed of the thin plate 3. By the rise of the thin plate holding plate 7, the respective thin plates 3 are sequentially pushed up and discharged. Then, when the thin plate holding plate 7 of the elevator 6 reaches the uppermost position by this payout and the thin plate 3 in the storage groove 5 disappears, the payout ends.

Next, a plurality of thin plates 3 are stored in the other storage groove 4 as a thin plate group, and the thin plate holding plate 7 of the elevator 6 descends to the lowest position. Then, the rotary drum 1 is rotated by 180 degrees to position the storage groove 4 with respect to the thin plate holding plate 7.

Therefore, the thin plates 3 are paid out only during this stage change. It will be suspended. Therefore, on the side of the device used in combination with this device, the operation must be temporarily stopped in accordance with the stage change.

[0009]

As described above, when the elevator 6 is lowered and the rotary drum 1 is rotated to change the stage, the payout of the thin plate 3 is temporarily stopped and the thin plate 3 is continuously moved. It is difficult to pay. Therefore, an object of the present invention is to provide a thin plate dispensing device that can continuously dispense thin plates.

[0010]

According to the present invention, there is provided a first transport mechanism for transporting a group of thin plates at a speed corresponding to a payout of a thin plate, and a second transportable mechanism for transporting the group of thin plates and passing them to the first transport mechanism. The transport mechanism, an auxiliary feeder that assists the transport of the thin plate group by the first transport mechanism, and the auxiliary feeder that detects the proximity of the thin plate group transported by the second transport mechanism to the thin plate group transported by the first transport mechanism. A thin plate dispensing device, which is provided with an auxiliary control means for temporarily stopping the assistance of conveyance and is intended to achieve the above object.

In this case, the second transport mechanism, when the thin plate group is supplied, transports the thin plate group at a speed higher than the transport speed of the first transport mechanism and transfers it to the first transport mechanism. It is to be integrated with the thin plate group.

Further, the auxiliary control means detects the proximity of the thin plate group transported by the second transport mechanism by the proximity sensor provided in the auxiliary feeder while the auxiliary feeder assists the transport of the first transport mechanism. Then, the auxiliary feeder is separated from the thin plate group of the first transfer mechanism to temporarily stop the auxiliary transfer, and when the thin plate group of each transfer mechanism is integrated, the auxiliary transfer is performed again.

[0013]

By providing such means, the thin plate group is conveyed by the first conveying mechanism at a speed according to the payout of each thin plate, and at this time, the thin plate group is conveyed by pushing, for example, from the rear by an auxiliary feeder. To assist.

In this state, when the head of the thin plate group fed by the second transport mechanism approaches the rear of the thin plate group transported by the first transport mechanism, this is detected by the proximity sensor of the auxiliary control means and the auxiliary feeder Temporarily leave the group of sheets. As a result, the thin plate groups are integrally transported by the first transport mechanism. Then, the auxiliary feeder again pushes the integrated thin plate group from the rear side to assist the conveyance.

Since both the thin plate groups 11 are integrated, the thin plates 12 can be continuously dispensed without any temporary interruption of the dispensing. As a result, the device used in combination with this dispensing device can be efficiently operated without being temporarily stopped.

The present invention is not limited to the above-mentioned embodiment, but may be modified within the scope of the invention. For example, the first and second transport mechanisms 10 and 20 may be any mechanism, and the first transport mechanism 10 uses a belt,
The second transport mechanism may use a feed O-ring.
The transport speed of the second transport mechanism 20 is the same as that of the first transport mechanism 10.
Since it suffices to catch up with the preceding thin plate group 11 being conveyed in, the speed change is not limited. Furthermore, not only the connection of the first and second transport mechanisms 10 and 20,
It is also possible to connect each transport mechanism in three or more stations. On the other hand, the proximity sensor 42 is not limited to being provided in the auxiliary feeder 40, but a line sensor may be arranged along the transport direction to detect the proximity state.
