Description

[Detailed Description of the Invention] The present invention relates to a paper sheet transfer device that transports paper sheets such as mail to a predetermined location and then transfers them to another transport mechanism.

The paper sheet transfer device described in this invention is installed on the way to send mail that has been sorted by a sorting machine to a bundling device that bundles the mail, and transports the mail that has been taken out from the sorting machine. However, it is a device for transferring to another transport mechanism connected to the bundling device, and constitutes a part of the device that automatically performs everything from sorting to bundling.

Conventionally, in this type of paper sheet transfer device, as shown in FIG. 1, a push plate 2 having a shape similar to the inner cross section of the bucket 1 moves inside the bucket 1 of the first transport mechanism. The mail 3 loaded on the bucket 1 is pushed out and transferred to the bucket 5 of the second transport mechanism via the horizontal plate 4. However, if the loaded mail becomes tilted during transportation,
Before the transfer, as shown in Figure 2, the paper sheets are supported from the paper exit 1a of the bucket 1, and after the transfer, as shown in Figure 3, the paper sheets are supported from the entrance 5a of the bucket 5. Since there were no walls, the mail had the disadvantage that it could collapse during transfer and end up outside the bucket.

The present invention eliminates the above-mentioned drawbacks and provides a paper sheet transfer device that can reliably transfer even poorly stacked mail. That is, the present invention includes a first transport mechanism that loads paper sheets and transports them, a second transport mechanism that receives and transports paper sheets in the first transport mechanism, and a comb-shaped transport mechanism. a first gate mechanism that closes the exit of the first transport mechanism and prevents paper sheets in the transport mechanism from collapsing to the outside through the exit; It has a similar shape to the comb-tooth opening of the push plate, and closes the entrance of the second conveyance mechanism without interfering with the push plate, so that the paper sheets transferred by the push plate are passed through the entrance to the outside. It is characterized by having a second gate mechanism that prevents the structure from collapsing.

Next, one embodiment of the present invention will be described in detail with reference to the drawings. FIG. 4 is a diagram showing an embodiment of the present invention.

In FIG. 4, the bucket 1 of the first conveyance mechanism 7 is connected by a chain (not shown), driven by a motor (not shown), and guided by parallel front and rear covers 27, 28. The paper sheets move in the horizontal direction with the inlet 1b and the outlet 1a both closed.
The bucket 1 is stopped by a switch 8.
At the stop position of the bucket 1, the front and rear covers 27, 2 facing the loading port 1b and the loading port 1a of the bucket 1 are installed.
A notch 8 is provided, and this notch is used to transfer paper sheets to a bucket of a second conveyance mechanism which will be described later.

The comb-shaped push plate 2 is connected to a motor 10 via a belt 9.
When it moves in the direction of arrow A, it pushes the mail 3 in the bucket 1 and transfers it. The push plate 2, the belt 9, the motor 10, the switch 11, which detects the completion of the pushing operation of the push plate 2 by the switch 11, and detects the end of the return operation by the switch 12,
The switch 12 constitutes an extrusion mechanism 13.

The first gate mechanism 14 is installed above the horizontal plate 4 that serves as a transfer path, and when the closing plate 15 is driven by an air cylinder 16 and lowers, the plate 4 of the bucket 1 reaches its bottom dead center. It is designed to block the outlet 1a for paper sheets facing to the side. The switch 17 detects the end of the downward movement of the plate 15, and the switch 18 detects the end of the return movement.

The second gate mechanism 19 is installed below the plate 4, and uses an air cylinder 21 to move up and down a holding plate 20, which has a shape similar to the gap between the comb teeth of the pushing plate 2. The comb-teeth portion of the holding plate 20 presses against the plate 4 when rising.
The paper sheet passes through the opening 4a and projects above the plate 4, and closes the paper sheet inlet 5a facing the plate 4 side of the bucket 5 without interfering with the pusher plate 2. The switch 22 causes the lifting operation of the restraining plate 20 to end.
The switch 23 detects the end of the return operation.

The bucket 5 of the second conveyance mechanism 24 is driven by a chain, a motor, etc. (not shown), and is guided by parallel front and rear covers 6, 26, and the front and rear covers 6, 26 open the inlet 5a and outlet 5b for paper sheets. They each move vertically in a closed state. The bucket 5 is stopped by a switch 25. At the stop position of the bucket cart 5, the front and rear covers 6, 26 facing the carry-in port 1b and the carry-out port 1a of the bucket cart 5 are cut out, and paper sheets are received from the first conveyance mechanism using the cut-out portions.

In FIG. 4, the bucket 1 of the first transport mechanism 7 loaded with mail 3 is stopped at a position where the front and rear covers 27, 28 are cut out by the switch 8. At this time, the closing plate 15 of the first gate mechanism 14 is inserted into the notch of the front and rear covers 27 from above, and is in a position where it blocks the outlet 1a of the bucket bag 1. On the other hand, the holding plate 20 of the second gate mechanism 19 is in a position to close the loading port 5a of the bucket bag 5 through the opening 4a of the plate 4. When the bucket 1 stops and the bucket 5 of the second transport mechanism 24 is stopped by the switch 25, the switch 8 and the switch 25 close the air cylinder 16 of the first gate mechanism 14 and the second gate mechanism 19. Air cylinder 2
Operate 1. As a result, the air cylinder 16 raises the closing plate 15 and turns on the switch 18. The restraining plate 20 is lowered by the air cylinder 21, and the switch 23 is turned on. The motor 10 of the push-out mechanism 13 is rotated by the switch 18 and the switch 23, and the push plate 2 moves in the direction of arrow A. The mail 3 passes over the plate 4 and is transferred to the bucket 5 through the carry-in port 5a. The end of the insertion operation of the push plate 2 is detected by the switch 11, and the switch 1
1 operates the air cylinder 21 of the second gate mechanism 19 to cause the holding plate 20 to protrude above the plate 4. At this time, the push plate 2 is located closer to the bucket bag 5 than the holding plate 20 is. The end of the upward movement of the holding plate 20 is detected by the switch 22, and the motor 10
Rotate the switch in the opposite direction to that of the switch 18.
The rotation of the motor 10 causes the push plate 2 to move in the direction opposite to the arrow A. Since the pushing plate 2 and the plate 20 are shaped so that they do not interfere with each other, the pushing plate 2 and the holding plate 2 are shaped so that they do not interfere with each other.
Pass through the gap at 0 and return to the position before transfer.
The end of the return movement of the push plate 2 is detected by the switch 12, and the switch 12 operates the second transport mechanism 24 to vertically transport the bucket 5 loaded with mail items 3. Similarly, the switch 12 operates the air cylinder 16 of the first gate mechanism 14 to lower the closing plate 15. The switch 17 detects the end of the lowering of the closing plate 15, moves the first transport mechanism 7, and transports the next bucket 1 to the transfer position.

The operation of the push plate 2, the closing plate 15 and the holding plate 20 in Fig. 4 is shown in Figs. 5a to 5e. Fig. 5a shows the state before transfer, in which the closing plate 15 and the holding plate 20 are respectively closing the carry-out exit 1a of the bucket 1 and the carry-in entrance 5a of the bucket 5.
After the bucket 5 stops, the blocking plate 15 and the holding plate 20
opens the discharge opening 1a of each bucket 1 and the discharge entrance 5a of each bucket 5, so that the push plate 2 can push the mail pieces 3 and transfer them, as shown in FIG. 5b.

After the paper sheets are transferred to the bucket 5, the holding plate 20 protrudes as shown in FIG. 5c. Next, Figure 5 d
As shown in FIG. 5, the pusher plate 2 intersects with the retainer plate 20 and returns to the starting position, and again as shown in FIG. 5e,
The closing plate 15 descends and returns to its initial state.

During this series of operations, the mail piece 3 is not supported on its sides only during the pushing operation of the pushing plate 2 shown in FIG. has been done. Therefore, when the mail item 3 is tilted during transportation, conventionally, at the time of FIG. 5a before transfer or at the time of FIG. 5e after transfer,
Even if it collapses outward due to lack of lateral support,
In the present invention, the former is blocked by the blocking plate 15 of the first gate mechanism 14, and the latter is blocked by the restraining plate 20 of the second gate mechanism 19, respectively, so that the bag will not collapse outside. Without,
Completely transferred.

As described above, according to the present invention, all mail can be supported before and after transfer, and even mail that is poorly stacked can be transferred reliably without falling apart. It is something.

In addition, in the example, during the extrusion operation, 4 of the paper sheets
Although the surface is not supported, this is because the mail is pushed out in about 1 second, and the transfer is completed before it collapses. However, if the transfer takes a long time, a mechanism exactly the same as the push-out mechanism 13 is provided on the opposite side of the bucket 5 from the bucket 1, and
By moving the push plates synchronously, the front and rear of the mail can be supported by the push plates, and the left and right sides can be supported by buckets, making it possible to support all four sides during transfer. Moreover, although only the plate 4 is shown between the buckets 1 and 5, it goes without saying that it is effective to provide guide plates on the left and right sides of the plates 4 to support the sides of the paper sheets.
