Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet stacking / conveying device for stacking a predetermined number of sheets and then collectively transporting the sheets.

[0002]

2. Description of the Related Art Conventionally, as a device for temporarily accumulating conveyed paper sheets and then collectively conveying the accumulated paper sheets to the next position, there is a device disclosed in JP-A-63-315442. .

In the apparatus described in this publication, for example, in the case of banknotes, the banknotes are conveyed in the lateral direction, and the rear ends of the banknotes are sequentially stacked by being blown by the blades of the impeller toward the stacking position in the stacking space. This is done by adjusting the position of the regulation member with which the leading end of the bill in the feeding direction abuts against the dimensional difference of the bill in the lateral direction.

Therefore, the front ends of the bills fed to the stacking position come into contact with the regulating member and stop, and the rear end is slid downward by the blades of the impeller to stack the bills.

[0005]

By the way, recently, along with the diversification of machine specifications, there has been a demand for a machine having specifications for conveying paper sheets such as banknotes in the longitudinal direction.

When the above-mentioned conventional apparatus is applied to such a requirement of the longitudinal conveyance specification, when the paper sheets conveyed in the longitudinal direction are discharged into the stacking space, the flexibility of the paper sheets themselves and the like. Buckling is likely to occur due to folding (especially in the case of banknotes, it is often folded and distributed in the direction perpendicular to the longitudinal direction of the bill). With the structure that presses the edges, it is almost impossible to collect the paper sheets in a batch-transportable state.

Particularly, when the folded leaflets are discharged into the stacking space and the trailing end is in a state of being flipped up by the folding, the trailing edge of the leaflets cannot be pressed by the blades of the impeller. As a result, jamming will occur without being able to obtain a stacking state that allows batch transport. Then, if the conveyance belt to the next position is driven while the stacking failure occurs in this way, there is a problem that the paper sheets are jammed or left in the stacking space.

[0008]

SUMMARY OF THE INVENTION According to the present invention, even when the sheets are conveyed and accumulated in the longitudinal direction, the sheets are surely accumulated, and troubles such as clogging of the sheets and remaining in the accumulating space. It is an object of the present invention to eliminate all the paper sheets that have been conveyed through the conveyance path between the blades at the end position of the conveyance path and discharge them at a predetermined rotation position. In addition to rotatably providing the above-mentioned impeller, there is provided a conveyor belt at a lower position of the impeller, which is capable of accumulating paper sheets discharged from the impeller blades into the accumulating space on the upper surface, and which constitutes a starting end of the carry-out conveying path. The holding member is provided so as to be swingably driven between a holding position where the conveying belt comes into contact with the sheet stacking position and a retracting position where the conveying belt is retracted upward.

Therefore, the paper sheets conveyed through the carry-in / conveyance path rotate while being received between the blades of the impeller, are discharged from between the blades at a predetermined position, and are sequentially accumulated at the accumulation position on the conveyor belt. At this time, the pressing member is in the retracted position and does not hinder the stacking.

When the carrying-in of the paper sheets by the carrying-in / carrying path is completed, the pressing member is driven to press the upper surface of the paper sheets stacked at the stacking position. Around this time, the conveyor belt is driven to collectively deliver the accumulated paper sheets.

Even when there is a stacking failure such that the trailing end of the paper sheet in the feeding direction is on the blade of the impeller at the time of stacking,
The paper sheet is pressed by the pressing action caused by the pressing of the pressing member, so that the above-mentioned state of defective stacking is eliminated, and normal batch feeding is performed.

Next, the operation of the above embodiment will be described. First, the outline of the deposit operation of the banknotes P will be described. In FIG. 1, the banknotes P inserted into the banknote insertion slot 3 are transferred one by one by the transfer mechanism 2, and the transferred banknotes P are transferred by the width-shifting mechanism 6. The positions on one side are aligned and sent to the identification unit 7, the denominations, authenticity, etc. are identified, and only normal banknotes are sent from the end portion 5a of the carry-in transport path 5 to the temporary holding unit 8 and abnormal banknotes ( Counterfeit banknotes, foreign banknotes, unidentifiable banknotes, etc.) 1
When switched to 0, it is sent to the return transport path 11 and returned to the return port 4.

The temporary holding section 8 includes the first and second pressing members 2
2 and 23 are in the upright retracted position (the position shown by the solid line in FIG. 2), and the stopper member 20 is in the upright posture.
And the conveyor belts 12a, 12a of the carry-out conveyor path 12 form an accumulation space.

Banknotes P fed into the above-mentioned temporary holding section 8
5 is discharged from the end portion 5a of the carry-in / conveyance path 5 and approximately half the length of the banknote P in the longitudinal direction enters between the blades 16a, 16a of the impeller 16, and the impeller 16 rotates in the direction of the arrow in FIG. In this manner, the tip of the bill P hits the bill dropping member 19 at the time when the bill P reaches the substantially horizontal posture, and the bill P is squeezed and accumulated on the belts 12a and 12a sequentially. After the stacking is completed, the first solenoid 31 and the second solenoid 38 are sequentially excited, and the operation of the drive mechanisms 30, 37 causes the first and second pressing members 22, 23 to sequentially rotate so as to enter the stacking space. , And the rollers 26 and 27 at the tips press the upper surface of the accumulated banknote P.

In the case of a folded bill, for example, as shown in FIG. 6, the impeller 16 rotates without the tip of the bill P entering the inner part between the blades 16a and 16a and being held, and the impeller 16 rotates. Sometimes I'm on the 16's. Even if such a state occurs, as described above, by the pressing operation of the first and second pressing members 22 and 23, all of them are laid on the conveyor belts 12a and 12a, and a normal stacking state is achieved.

Next, the carry-out / transport path 12 is driven and the stopper member 20 is laid down, so that the bills P accumulated on the carry-out / transport path 12 are conveyed to the conveyor belt 12a and the rollers 26 of the first and second pressing members 22 and 23. , 27 are carried out under the state of being sandwiched between them.

When the above-mentioned defective integration occurs,
Subsequent banknotes may crawl below the defective banknotes and be normally stacked, or may be stacked (bad) on the defective banknotes in the same way. Depends on the condition (folded, etc.). However, according to the above apparatus, when the succeeding banknotes are normally stacked, all the banknotes can be stacked and conveyed without any problem by holding down only one sheet having a stacking failure,
Even if a plurality of sheets are defective in stacking, they can be stacked and conveyed normally by rotating the impeller 16 while pressing them together by the first pressing member 22.

Next, the operation timing of each operation section of the temporary holding section 8 will be described with reference to the timing chart shown in FIG.

All banknotes P inserted into the banknote slot 3
Is temporarily held or returned (determined by the presence / absence of the banknote presence / absence detection sensors S, S ... of all the transport paths; timing A), and a predetermined time (1 s) has elapsed (timing B), the impeller drive The motor 46 stops and the receiving operation stops.

When a predetermined time (1 s) has further elapsed (timing C), the first solenoid 31 is excited to rotate the first pressing member 22 to a position for pressing the banknote P, and the temporarily accumulated banknote P is carried out. The transport belt 12a of the transport path 12,
12a (FIG. 7).

When a predetermined time (0.5 s) has passed since the first solenoid 31 was excited (timing D), the impeller drive motor 46 is restarted, and after the restart, a predetermined time (0.5 s). When the time elapses (timing E), the second
The solenoid 38 is excited, and the second pressing member 23 causes the bill P
The banknotes P are rotated to a position where the
It is pressed against 2a, and at the same time, the stopper member 20 falls down to open the passage (see FIG. 8).

After a lapse of a predetermined time (1 s), the drive motor of the carry-out / conveyance path 12 is driven to carry out the accumulated banknotes P collectively.

After the banknote presence / absence detection sensors S ₁ and S ₂ in the temporary holding section 8 are in the light transmitting state (timing G),
When a predetermined time (1 s) elapses (timing H), the excitation of the first solenoid 31 is released, the second solenoid 38 is subsequently demagnetized (timing I), and the temporary holding unit 8 returns to the next bill reception standby state. .

In the illustrated embodiment, the first and second two
Although the case where the two holding members 22 and 23 are used is shown, either one may be omitted and a single holding member may be used. Further, in the illustrated embodiment, the case where the present invention is applied to the temporary holding unit of the banknote depositing machine is illustrated, but the application to other target machines that collect paper sheets and then collectively remove them is arbitrary.

[0033]

As described above, according to the present invention, even if rectangular paper sheets such as banknotes are conveyed in the longitudinal direction and accumulated, the paper sheets having different lengths are conveyed. , It is possible to carry out as a normal stacking state regardless of the folded paper sheets, especially when handling banknotes, because there are many banknotes that are folded in the direction perpendicular to the longitudinal direction. It can be expected to have a remarkable effect on unloading.
