DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a paper sheet stacking apparatus, and more specifically, for example, in a bank or the like, paper sheets such as banknotes are bundled by a band,
The present invention relates to a paper sheet stacking device that stacks this at a certain place.

(Prior Art) An example of a conventional paper sheet stacking apparatus will be described with reference to FIG.

The paper sheet stacking device 50 shown in the figure is a paper sheet bundled by a binding device (not shown) in a bundled state (hereinafter referred to as “pouch P ₀ ”).
(Also referred to as (in FIG. ₁ )), a carrier 51 that conveys in the directions of arrows X ₁ and X ₂ , a shutter 52 that is arranged so as to block the traveling path of the carrier 51, and an inclined surface below the carrier 51 and the shutter 52. Shooter 53 arranged like this,
Storage box 54 that is placed facing the discharge end of this shooter 53
And a stopper 55 rotatably arranged near the discharge end of the shooter 53, and the stopper 55 is provided with an arrow as necessary.
Electromagnetic solenoid 56 as a drive source for driving in the Z ₁ and Z ₂ directions
And a limit switch 57 as a detecting means arranged near the stopper 55.

When the small bundle P ₀ comes into contact with the stopper 55, the stopper 55 is normally rotated by the electromagnetic solenoid 56 in the direction of arrow Z ₂ to drop the small bundle P ₀ into the storage box 54, and at the same time, the small bundle P 0 The passing state of ₀ is detected by the limit switch 57, and the count signal of the small bundle P ₀ , the fall timing, etc. are detected by the detection signal.

In addition, when the small bundle P ₀ falls on the shooter 53, some abnormality, for example, when the limit switch 57 continues to operate due to the presence of the small bundle P ₀ , the electromagnetic solenoid 56
Does not operate, thereby preventing the subsequent small bundle P ₀ from dropping into the storage box 54.

However, since the conventional device 50 having the above-mentioned configuration is provided with only one limit switch 57 as the detection means, for example, the upper limit switch 57 is provided as a regular grip P _0.
If an abnormal object (for example, an abnormal banknote) falls immediately after the regular small bundle P ₀ while is passing, the detection signal from the limit switch 57 continues, so the storage box 54 that is originally less than the accumulated capacity is full. An erroneous operation occurs in which the image is discriminated as if it exists.

Further, in the conventional device 50, since the shooter 53 using the inclined surface is used, for example, when adhesive dust or the like adheres to the shooter surface 53a in the vicinity of the stopper 55, even if the stopper 55 rotates. The small bundle P ₀ did not fall into the storage box 54 at the regular timing, and there was a high probability that an abnormality occurred although it was not originally abnormal.

In addition, in the conventional device 50, the grip is placed on the shooter 53 from the Y direction.
Even if an abnormality occurs after P ₀ has dropped, an abnormal object or the like often falls into the storage box 54 due to a delay in the operation of the stopper 55, and there is also a problem that a stable transport state of P ₀ cannot be obtained.

(Problems to be Solved by the Invention) As described above, in the conventional device, malfunction or liable to occur,
In addition, there is a problem of lacking stability.

Therefore, it is an object of the present invention to provide a paper sheet stacking device capable of preventing a malfunction due to mixing of an abnormal substance and obtaining a stable paper sheet transport state.

It has two and. The transport state recognition unit 9a, the full alarm generation unit 11a, and the abnormality alarm generation unit 11b constitute the transport state recognition unit 9.

As shown in FIG. 1, the transport means 3 includes a driving pulley 13
And a driven pulley 14 and a belt 15 that is stretched between the pulleys 13 and 14 to form a transport path for the small bundle P ₀ , and is driven by a drive motor (not shown) included in the transport control means 10.
In the figure, the small bundle P ₀ is conveyed in the direction of arrow X ₁ . In FIG. 1, 17 is a guide plate.

The second detecting means 8 detects a small amount P ₀ of the carrier 16 falling on the belt 15 within a certain time while the carrier 16 moves from the binding position shown in FIG. Is output, and the presence of an abnormal object such as an abnormal bill other than the small bundle P ₀ is also detected.

The first detecting means 5 is a gripper that is conveyed on the belt 15.
The presence of P ₀ is detected by the operation of the operation lever 4a, a detection signal is output, and when the small bundle P ₀ is staying on the operation lever 4a, the continuous detection signal indicating the stay is continuously output. There is.

The transport state recognizing unit 9 takes in the detection signal from the first detection unit 5 and the detection signal from the second detection unit 8 simultaneously via the CPU 12, or both detection signals within a certain time. When it is loaded, it recognizes that there is an abnormal object other than the normal bundle P ₀ on the belt 15 and sends an abnormal signal to the CPU 12 and an abnormal alarm signal to the abnormal alarm generation unit 11b. ing.

Further, the transport state recognition unit 9a recognizes the occurrence of an abnormality even when the second detection means 8 does not output the detection signal within the fixed time during which the carrier 16 moves, and at this time, the abnormality signal is output as in the case described above. , An abnormal alarm signal is sent out.

Further, when the transport state recognition unit 9a receives the continuation signal from the second detection unit 8, the small bundle P ₀ on the belt 15 is filled from the inside of the storage unit 2 to the discharge end region of the transport unit 3. State, that is, it recognizes that it is staying due to being full, at this time, a full signal to the CPU 12,

The carrier 13 is reset by a carrier driving unit (not shown) which has received an abnormality signal sent from the conveyance state recognizing means 9 when an abnormality occurs, and discharges the small bundle P _{0 being} conveyed onto the belt 15. Has become.

Next, referring to FIG. 3 (a),
The description will be made also with reference to (b) and (c).

First, the operation when an abnormality occurs in this device will be described.

As shown in FIG. 3 (a), the small bundle P ₀ is X by the carrier 16.
The belt 15 from the carrier 13 to the stopper 52.
Fall on. Then, the small bundle P ₀ is carried by the carrying control means 10 together with the belt 15 driven in the X ₁ direction.
At this time, first, the small P ₀ dropped by the second detection means 8
Is detected. At this time, the second detection means 8 sends a detection signal indicating the passage of the small bundle P ₀ to the transport state recognition unit 9a via the CPU 12.

The small bundle P ₀ on the belt 15 eventually hits the operating lever 4a of the first detecting means 5 and, after operating the operating lever 4a, is discharged from the discharging end portion into the storing means 2.

In this case, the first detection means 5 sends a detection signal to the conveyance state recognition unit 9a of the CPU 12 as the small bundle P ₀ passes.

The transport state recognizing unit 9a uses the above-mentioned first and second detecting means 4,
When the input timing of each detection signal from 8 is a preset fixed time, neither an abnormal signal nor an abnormal alarm signal is issued, but as shown in FIG. 3 (b), the first detecting means 5 precedes _{When 0} is detected and the second detection means 8 detects, for example, the abnormal bill P ₁ , both detection means are detected.
Since the detection signals from 5 and 8 are simultaneously input, it is recognized that an abnormality has occurred at this time, and the abnormality signal is sent to the conveyance control means 10 via the CPU 12 and the abnormality warning signal is sent to the abnormality warning generation unit.
Send to 11b respectively. As a result, the conveyance control means 10 controls the conveyance means 10 to stop, and stops the small P ₀ conveyance on the belt 15. Such an operation, the housing means 2 normal bunch are integrated within P _0, it is possible to distinguish between bunch P ₀ due to abnormality remaining on the belt 15 at the time of abnormality occurrence .

Further, the conveyance state recognition unit 9a, even when the input timing of each detection signal from both detection means 5, 8, is a timing shorter than a predetermined constant time, recognizes that an abnormality has occurred as in the case described above, As a result, the stop control of the conveying means 3 and the sending of the abnormality alarm signal are performed as in the case described above.

Furthermore, despite the fact that carrier 16 is in operation,
Even when the detection signal from the second detecting means 8 is not sent to the carrying state recognizing section 9a, the carrying state recognizing section 9a recognizes the occurrence of an abnormality, and as a result, the carrying means 3 is caused by the occurrence of the abnormal signal.
Stop control and an abnormal alarm signal are sent.

Abnormal alarm generation unit 11b receiving the above-mentioned abnormal alarm signals
Generates an alarm such as a buzzer sound according to each input timing.

As a result, the operator of this device can recognize the occurrence of an abnormality by ear, and can take necessary measures such as repairing the abnormal portion.

Further, after carrying control for stopping the carrying means 3 based on the abnormal signal, the carrying control means 10 does not re-drive the carrying means 3 even if a reset signal by an operator is inputted, and this state is maintained until the abnormal place is recovered. To continue. Thus, a normal bunch P _0, the distinction between bunch P ₀ due to the abnormality can be performed more accurately.

When the above-mentioned abnormality occurs, the carrier 16 discharges the small bundle P _{0 being} conveyed onto the belt 15 whose stop is controlled by the reset operation of the carrier driving unit (not shown) which is operated by the abnormality signal.

Thus, since the bunch P ₀ on the carrier 16 is that all remain on the belt 15 at the time of abnormality occurrence, the distinction between normal bunch P ₀ in the storage unit 2, a bunch P ₀ due to abnormality Can be reliably performed.

Next, with reference to FIG. 3C, the operation of detecting the full state of the storage means 2 will be described.

As shown in the figure, a considerable number of small bundles P ₀ have already been accumulated in the storage means 2, and further, in the area of the discharge end of the conveying means 3 as well.
In a state in which P ₀ is stacked, further to bunch P ₀ succeeding when you try to transport the X ₁ direction by the conveying means 3, because of the presence of each bunch P ₀ The subsequent bunch P ₀ is the preceding, first Stays on the operation lever 4a of the detection means 5 of FIG.

At this time, the first detection unit 5 sends a continuation detection signal indicating the staying state of the small bundle P ₀ to the transport state recognition unit 9a via the CPU 12.

Based on the continuation detection signal, the conveyance state recognition unit 9a sends an abnormality signal to the conveyance unit 19 via the CPU 12 and a full alarm signal to the full alarm generation unit 11a.

As a result, the conveyance control unit 10 controls the conveyance unit 3 to stop, the belt 15 stops, and the full alarm generation unit 11 issues a full alarm to notify the operator of the full information. Further, according to this embodiment apparatus described above, bunch so as conveying means 3 P ₀ adopts belt conveyor type, bunch compared with the conventional apparatus using the inclined surface P ₀
Can be carried more reliably without being affected by the presence of dust or the like.
