Abstract

PURPOSE:To obtain a take-off device for the paper sheets at high speeds by providing a procurement device and a delivery device independently. CONSTITUTION:When the inlet port 15 of a procurement device 11 abuts against a letter 21, the inlet port 15 which is the tip end of the procurement device 11, is parted from an accumulating section 19 so as to be within a belt 17. Accompanied with the action, the letter 21 is brought in the belt 17 side so that it is stopped at the position of the belt 17. On the other hand, suction device 13 starts sucking when the driving is started so that the letter 21 is taken off out of the accumulating section 10 by means of the procurement device 11 and the belt 17. In this case, the letter is stopped at the position of the belt 17, the belt 17 is however, rotated, the letter 21 thereby starts moving to the direction shown by an arrow head while being teamed with the rotation. By this constitution, the paper sheets can thereby be taken off positively at high speeds.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a paper sheet retrieval device for processing, for example, large-sized postal letters.

(Prior art) As shown in FIG. 3, for example, the paper sheet retrieval device moves the retrieval section 1 back and forth with respect to the letter 3 as shown by the arrow a, and picks up the letter closest to the retrieval section 1. Perform a suction operation on letter 3 and take out letter 3. After that, this order section 1
By moving in a direction parallel to the surface of the letter 3 as shown by the arrow mark, the letter 3 was taken out and prepared for conveyance. After that, he repeated this process and retrieved the accumulated letters.

However, in such a device configuration, two operations,
In other words, since the ordering operation and the sending operation were performed by a single mechanism, it was not possible to send out the product at high speed.

(Problems to be Solved by the Invention) As described above, with the conventional technology, paper sheets cannot be taken out at high speed in the paper sheet take-out device.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a paper sheet retrieval device which eliminates the above-mentioned drawbacks and can realize sheet retrieval at high speed.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above problems, the present invention is characterized in that an order section and a sending section are provided independently.

(Function) In the present invention, since the ordering section and the sending section are provided independently,
Since the movements of both parts are simple, they can be made faster. Therefore, according to the present invention, paper sheets can be taken out at high speed.

(Example) Next, an example of the present invention will be described using the drawings. In the apparatus of this embodiment, as shown in FIG.
and a suction device 13. Of these, the ordering device 11 is movable progressively in the direction of arrow C, and has a pair of suction ports 15 at its tip. A belt 17 is provided so as to surround the ordering device 11 and the suction device 13. The belt 17 is an endless belt, and as shown in FIG. 2, it has two belt portions 17a,
17b. This belt 17 is rotated by rollers in the direction shown by arrow d in FIG.

A letter accumulation section 19 is provided opposite the front surface of the belt 17. In this storage section 19, the letter 21 is stored on the belt 1.
It is accumulated parallel to the front surface of 7. The purpose of the paper sheet retrieval device here is to take out the letters 21 one by one and deliver them to a conveyance path.

In such an arrangement, the ordering device 11 can move progressively in the direction of arrow C, and in the standby state, the suction port 15
is located within the belt 17.

This ordering device 11 is driven by a drive means (not shown), and the suction port 15 at the tip thereof comes out from the front side of the belt 17, which is separated into two strips.

Moreover, the suction port 15 is in contact with the surface of the foremost letter 21 placed in the storage section 19.

Further, the suction device 13 fixes paper sheets that come to the front side to the belt 17 by suctioning from the front side thereof.

The operation in such a configuration will be explained.

When taking out letters 21, which are paper sheets, from the storage section 19, the belt 17, the ordering device 11, and the suction device 13 are driven. The belt 17 is driven by rotation, and the ordering device 11
The drive is suction and movement towards the letter side. Due to the latter movement, the suction port 15 of the ordering device 11 comes into contact with the letter 21. In this state, the retrieval device 11 is moved in the opposite direction to that described above, that is, the suction port 15, which is the tip of the retrieval device 11, is separated from one of the storage portions and enters the belt 17. With this operation, the letter 21 is brought to the belt 17 side and stopped at the belt 17 position. As is clear from FIG. 2, the movement of the letter is stopped by the belt 17 which is separated into two strips, and the letter is stopped at the position of the belt 17.

On the other hand, the suction device 13 performs suction when driving is started. Then, the letter 2 is retrieved by the ordering device 11 and the belt 17.
1 is taken out from the storage section 19 and stopped at the belt 21, but the belt 21 is rotating as described above.
Along with this rotation, the letter 21 starts moving in the direction of the arrow 21.

At this time, no force is applied to the letter 21 by the ordering device 11 . Therefore, if the letter 21 remains as it is, it will be extremely unstable and will not be transported. However, since the letter 21 is sucked by the suction device 13 and fixed to the front surface of the belt 17, it is conveyed as it is by the belt 17 and is supplied to the next stage conveyance device (not shown).

Note that, as shown in FIG. 2, the belt 17 is provided with holes intermittently. This is because a part of the suction surface of the suction device 13 is blocked by the belt 17, and the letter 21 can be sucked even in this blocked portion. Furthermore, while the suction surface of the suction device 13 is separated from the letter 21 by the thickness of the belt 17, the holes in the belt 21 are in direct contact with the letter 21, making the suction more stable. In this way, the letter 21 is more firmly fixed to the belt 17 by the suction device 13.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. For example, although the ordering device 11 is a movable type equipped with a suction port, the same effect as in the above embodiment can be achieved even if the ordering device 11 is not a movable type by controlling the on/off of the suction force. .

[Effects of the Invention] As explained above, according to the present invention, paper sheets can be taken out reliably and at high speed.
