Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a paper sheet sorting apparatus that sorts paper sheets such as postal matter according to destinations.

[Technical Background of the Invention] Conventionally, as a sorting device for mail, the one shown in Fig. 11 is known.

In this apparatus, first, the mail pieces loaded in the supply unit 1 are taken out one by one by the take-out unit 2, the postal code is read by the reading unit 3, and the postal code is passed through the reversing unit 4, the aligning unit 5, and the direction changing unit 6. , Are sorted in the row direction by the stage pass gates 7, are transported by the transport path 8 of each row, and are stacked in the corresponding stacking unit 10 by the operation of the gate 9 corresponding to the postal code during the transfer. In this apparatus, the stacking unit 10a farthest from the supply unit 1 is a stacking unit that stacks paper sheets that are not sorted (hereinafter referred to as rejected) due to the fact that the sorting information is not obtained. Has been done.

FIG. 12 is a side view showing the configuration in the vicinity of the stacking unit 10 in this device.

In this device, a conveyance path 8 is provided in the row direction along the opening of the stacking unit 10 arranged in a matrix, and a gate 9 is provided near the opening of each stacking unit 10 so that the reading unit 3 can read. The gate 9 corresponding to the designated postal code is operated, and the postal matter is distributed to the target stacking unit 10. Reference numeral 11 is a forced distribution plate provided near the opening of the stacking unit 10a for rejecting, and has a role of forcibly distributing the rejected mail to the stacking unit 10a.

As can be seen from these figures, in the conventional sorting apparatus, since the mail items to be sorted are conveyed in the row direction of the stacking unit arranged in a matrix from the side close to the supply unit 1 to the side far from the supply unit 1.
The stacking unit 10a, which collects rejected mail items, is necessarily located in the farthest row from the supply unit 1.

FIG. 13 is a diagram showing the configuration of a conventional sorting device in which the left-right relationship between the matrix-shaped stacking unit and the supply unit 1 is reversed.

In this apparatus as well, the stacking unit 10a for stacking rejected mail items is located in the farthest row from the supply unit 2.

[Problems of the Background Art] However, if a stacking unit for collecting rejected mail items is provided in a row farther from the stacking unit as in the conventional apparatus, the rejected paper sheets are re-wound. If the operator wants to process the product by mounting it on the supply unit 1, the worker has to go to the collecting unit 10a for rejecting the mail at the end of the apparatus, but this work is very laborious. was there.

That is, since such a sorting device has a lateral dimension of several meters, it takes a considerable amount of time to move from the vicinity of the supply section 1 of the device to the end, and the number of tens of thousands of devices per hour. Because of its processing power, this move must be done frequently.

Further, in the conventional apparatus, a step pass gate 7 for sorting the postal matter passing through the reading section 3 in each row direction is provided near the supply section 1. However, the operation noise of the step pass gate 7 is very large, and the normal supply is performed. There was also the problem that it was extremely noisy for the workers near Part 1.

[Object of the Invention] The present invention has been made to solve the problems of the conventional sorting device as described above, and the work of taking out rejected paper sheets and the like can be performed very easily. Moreover, it is an object of the present invention to provide a paper sheet sorting apparatus which produces a quiet operation sound for the workers in the supply section.

[Summary of the Invention] In order to solve the above problems, the present invention relates to a sorting device for sorting paper sheets, in which a stacking unit arranged in a matrix is conveyed in a row direction from a side far from a supply unit. By moving the position of the stacking unit that collects the rejected paper sheets toward the near side to the supply unit, the worker can easily take out the rejected paper sheets and The stage pass gates that are distributed in each row direction are located far from the supply unit so that the operation noise for workers near the supply unit is quiet.

Embodiments of the Invention Hereinafter, details of embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an elevational view showing the structure of an apparatus according to an embodiment of the present invention, in which parts common to those in FIGS. 11 to 13 described above are designated by common reference numerals.

The apparatus of this embodiment includes a supply unit 1 for supplying a paper sheet in which sorting information such as a postal code is previously written, a take-out unit 2 for taking out the paper sheets one by one from the supply unit 1, and a taken-out paper sheet. A reading unit 3 that reads the sorting information from the leaves, a stage pass gate 7 that sorts the taken-out paper sheets in the row direction, a conveyance path 8 that is provided in the row direction, and a specific paper sheet from the conveyance path 8. The stacker includes a gate 9 (described later) for sorting the sheets and a stacking unit 10 having openings above and arranged in a matrix, and the paper sheets that have passed through the reading unit 3 are conveyed to the side far from the feeding unit 1. After that, it is conveyed in the row direction to the side closer to the supply unit 1.

That is, in the apparatus of this embodiment, the stage pass gate 7 for sorting the conveyed paper sheets in the row direction is provided on the side far from the supply unit 1, and the stacking unit 10a for collecting the rejected paper sheets is the supply unit. It is provided in the row closer to 1.

FIG. 2 is a side view showing a specific structure in the vicinity of the stacking unit 10 of the device of this embodiment.

In the apparatus of this embodiment, the paper sheets conveyed in the row direction by the conveying unit 8 starting from the accumulating unit 10b (FIG. 1) provided on the farthest side from the feeding unit 1 are opened above the accumulating unit 10. It is dropped from the part to the inside by the operation of the gate 9.

Then, the paper sheets that have not been stacked in any of the stacking units 10 are forcedly distributed to the stacking unit 10a closest to the supply unit 1 by the forced distribution plate 11
To be dropped.

Thus, in the apparatus of this embodiment, the step pass gate 7 is the supply unit 1.
As a result of providing the stacking unit 10a, which is provided on the side far from
The worker can easily take out the rejected paper sheets, and as long as the worker is in the vicinity of the supply unit 1, the sound of the corrugated pass gate 7 can be felt quietly.

FIG. 3 is an elevational view showing the overall structure of another embodiment of the device of the present invention, in which parts common to those in FIG. 1 are designated by common reference numerals.

In this device as well, similar to the device of the previous embodiment, the step pass gate 7 is provided on the side far from the supply unit 1, and the stacking unit 10a for collecting rejected paper sheets is provided on the side close to the supply unit 1. The left-right relationship between the supply unit 1 and the stacking unit 10 is opposite to that of the apparatus of the previous embodiment. In this case as well, the same effect as that of the above-described embodiment apparatus can be obtained. In this embodiment apparatus, the function of each unit is the same as that in the previous embodiment apparatus.

It should be noted that, in any of the embodiments, the supply unit 1 to the extraction unit 2
Although the paper sheets taken out in the longitudinal direction are conveyed as they are in the longitudinal direction, if the direction changing section 6 is provided as shown in FIG. 4, the paper sheets taken out in the longitudinal direction are moved in the lateral direction. Since they are conveyed and then conveyed, the size of each stacking unit 10 in the row direction can be reduced.

Further, as shown in FIG. 5, the conveyance path 8 on the side closer to the supply unit 1 is converged, and one reject accumulating unit 10a is provided,
One stacking unit 10a for rejected paper sheets for each line
You may make it possible to take it out collectively.

Further, as shown in FIG. 6, while the transport path 8 on the side closer to the supply unit 1 is converged, the transport path after convergence is connected to the transport path of the supply system near the extraction unit 2 to reject the rejected paper sheets. May be returned to the supply system as it is, and the re-sorting may be continuously performed.

FIG. 7 is a diagram showing an example of the structure of the gate 9 to be provided near the opening of each stacking unit 10 of the paper sheet sorting apparatus of the present invention. In the figure, the conveyance path 8 is configured such that the first belt 8a, the second belt 8b, and the third belt 8c face each other, and the paper sheet P is conveyed while being sandwiched between these belts.

A detector 12 for the paper sheet P is provided on the conveyance path formed by the first belt 8a and the second belt 8b.

The second belt 8b is folded back by the movable roller 13, the third belt 8c is folded back by the fixed roller 14, and a space G is formed between these rollers.

The accumulating portion 10 has an opening below the space G, and the movable roller 13
Is attached to the arm 13a with the point S as a fulcrum, and based on the detection signal of the paper sheet P output by the detector 12 and the sorting signal output by the reading unit 2 described above, a rotary solenoid (not shown) ), Etc.

Then, the paper sheets (other stacking units) that are not stacked in this stacking unit 10
When the material to be stacked on the sheet 10 is conveyed, the movable roller 13 is set in the direction of the first belt 8a as shown in FIG.

Then, the paper sheets protruding from the conveyance path formed by the first belt 8a and the second belt 8b directly enter the conveyance path formed by the first belt 8a and the third belt 8c, It passes above the stacking unit 10.

On the other hand, when the paper sheets to be stacked on the stacking unit 10 are conveyed, the movable roller 13 is set in a direction away from the first belt 8a as shown in FIG.

Then, the paper sheet P protruding from the transport path constituted by the first belt 8a and the second belt 8b jumps out from the space G and falls into the stacking unit 10. In this case, since the movable roller 13 receives the force of the second belt 8b on its orbiting surface almost evenly, its displacement can be performed with relatively low power.

FIG. 9 is a diagram showing another example of the structure of the gate to be used in the device of the present invention.

In this example, the idle roller 15 is provided so as to be in contact with the third belt 8c.

The idling roller 15 rotates in the direction of the arrow as the third belt 8c revolves, and when the tip of the paper sheet P jumping into the space G hits the idling roller 15, a force acts in the falling direction,
The falling speed of paper sheets increases.

Further, since the edge E of the opening of the stacking unit 10 is inserted behind the idle roller 15, the probability of occurrence of a jam of the paper sheet P at this portion is low.

FIG. 10 is a diagram showing still another example of the structure of the gate to be used in the device of the present invention.

In this example, the first belt 8a is divided into belts 8a ₁ and 8a ₂ , and then the movable roller 13 is installed.

If any of the gates shown in FIGS. 7 to 10 is applied to the device of the present invention, it is possible to surely stack the paper sheets in the stacking unit 10.

[Effect of the Invention] As described above, in the paper sheet sorting apparatus of the present invention, the stacking unit arranged in a matrix is rejected by directing the conveying direction in the row direction from the side far from the supply unit to the side close to the supply unit. Since the position of the stacking unit for stacking the collected paper sheets is brought close to the supply unit, the worker can take out the rejected paper sheets very easily.

Further, in the apparatus of the present invention, since the step pass gate for sorting the conveyed paper sheets in the row direction can be provided at a position far from the supply section, the operation sound can be felt quietly by the worker near the supply section. .
