BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 3 are views showing an embodiment of a bill processing apparatus according to the present invention. Hereinafter, the configuration, operational effects, and modified examples of the present embodiment will be sequentially described.

[Structure] FIG. 1 shows a main part of an embodiment of a bill processing apparatus according to the present invention. This banknote handling apparatus includes a bundled banknote processing unit P1 that processes a banknote bundle and a loose banknote processing unit P2 that processes a loose banknote.
The banknote stacking unit (stacker) 7 for stacking loose banknotes is provided in the loose banknote processing unit P2. Banknotes that have been conveyed one by one from the left side in FIG. 1 by a conveyor belt or the like (not shown) are accumulated in the banknote accumulation unit 7.

The bill processing apparatus also includes a bundle conveying means 6 which is movable between the bundled bill processing unit P1 and the loose bill processing unit P2. In the loose banknote processing unit P2, the bundle transporting unit 6 holds a plurality of loose banknotes stacked in the stacking unit 7 as a stack B ′, extracts the stack banknotes in the banknote short-side direction from the stacking unit 7, and extracts the separated roses. The banknote bundle B'is conveyed to the banknote bundle processing unit P1 in the banknote longitudinal direction. In FIG. 1, only the grip portion of the bundle conveying means 6 is shown, but this grip portion includes three grip claws 60 extending forward,
It has 62 and 64.

The bundle B'of loose banknotes conveyed to the bundled bill processing unit P1 is sent to the bundling unit 10 by the bundle conveying means 6. In this bundling unit 10, a bundle B ′ of loose banknotes held by the holding means 11 is bound by a binding band W and sent out as a bill bundle B by the transport belt 12. The gripping claw 64 at the right end of the bundle conveying means 6 is the gripping means 1 of the binding portion 10.
In order to avoid interference with 1, it is possible to swing and retract backward.

Next, the banknote stacking section 7 of the loose banknote processing section P2.
The three cutouts 70 corresponding to the three gripping claws 60, 62, 64 of the bundle conveying means 6 are formed in the. Also,
On one side of the stacking unit 7, a bill aligning lever 74 swinging along the arcuate slit 72 is provided. The aligning lever 74 has a function of aligning the banknotes in the stacking unit 7 by continuously swinging during stacking of banknotes. Then, in the stacking unit 7, a pair of passage detection sensors (passage detection means) 3 arranged at intervals in the banknote longitudinal direction.
a and 3b are provided. The pair of passage detection sensors 3a and 3b are configured to be able to detect the time when the end of the bill passes at each position (optically by, for example, light blocking → light transmitting).

Further, behind the banknote stacking section 7 (right side in FIG. 1).
Is a pair of end detecting sensors (end detecting means) arranged so as to correspond to the outer sides of both ends in the longitudinal direction of the banknote B ′ extracted by the bundle conveying means 6. 4a and 4b are provided. The pair of edge detection sensors 4a and 4b are configured to be able to detect the edge of the banknote (optically by, for example, light transmission → light blocking) at each position.

Next, as shown in FIG. 2, the bill processing apparatus has a control unit 1 having a function as a control / judgment / clocking unit and a storage unit (storage unit) connected to the control unit 1.
2, an informing device (informing means) 5 and a conveyance drive device (conveyance drive means) 6D. In addition, the pair of passage detection sensors 3a and 3b and the pair of end portion detection sensors 4 described above.
a and 4b are also connected to the control unit 1.

First, the control unit 1 as a determination means has a function of determining whether or not a banknote is skewed based on the deviation between the passage times detected by the pair of passage detection sensors 3a and 3b. That is, if there is a deviation (exceeding a predetermined allowable range) at the passage time point detected by both passage detection sensors 3a and 3b, it is determined that the bundle B'of loose banknotes has skew. For example, when there is a bundle B ′ of loose banknotes that are skewed as shown by the two-dot chain line in FIG. 1, the pair of passage detection sensors 3
There will be a deviation in passing time corresponding to the distance A between a and 3b.

Further, the control section 1 as the judging means has a function of judging whether or not the banknote is protruding in the longitudinal direction based on whether or not the pair of edge detecting sensors 4a and 4b detect the edge of the banknote. There is. That is, if any one of the edge detection sensors 4a and 4b detects the edge of the banknote, it is determined that the bundle B ′ of loose banknotes has a protrusion in the longitudinal direction of the banknote.

The "protrusion" referred to here is the case where the position of the entire bundle B'is displaced from the predetermined gripping position of the bundle B'of loose banknotes by the bundle conveying means 6 (FIG. 1). ,
Both cases where some banknotes in the stack B ′ are out of position are included. FIG. 3A shows a bundle B ′ as an example of the latter.
1 schematically shows a case where one banknote S ′ among the loose banknotes S that compose the above is protruding in the longitudinal direction. For example,
When the banknote S ′ whose one end is warped in the stacking unit 7 as shown in FIG. 3B is extended as shown in FIG. 3A after being withdrawn, despite the operation of the banknote alignment lever 74. ,
Some of the banknotes S ′ will stick out in the longitudinal direction.

Next, when the bundle conveying means 6 conveys the bills in the longitudinal direction, the control unit 1 as a time measuring means detects the leading end of the bills by the end detection sensor 4a on the conveying direction side and then detects the rear end of the bills. It has a function of measuring the "passing time" until the part is detected (for example, light transmission → light shielding → light transmission).

Here, the storage unit 2 stores in advance the passage time corresponding to the length of the bill for each denomination as the "reference passage time". That is, generally, the length of the bill is slightly different for each denomination such as 10,000 yen or 1,000 yen. Assuming that the bundle B'of loose banknotes has no protrusion in the longitudinal direction of the banknote, the passage time corresponding to the length of the banknote for each denomination is "in relation to the transport speed of the bundle transporting means 6. “Standard transit time”.

Then, the control unit 1 as the judging means compares the measured passage time with the reference passage time stored in the storage unit 2 so as to extend the banknote in the longitudinal direction (here, the whole bundle B '. It has a function to judge whether or not there is a deviation). That is, the measured transit time is longer than the reference transit time (exceeding a predetermined allowable range).
If it is long, it is determined that the bundle B ′ of loose banknotes has a protrusion in the longitudinal direction of the banknotes.

Next, the transport driving device 6D drives the bundle transporting means 6 under the control of the control unit 1 as the control means, and causes the bundle transporting means 6 to perform the transporting operation as described above. Has become. Further, the notification device 5 is for notifying the abnormality of the bill processing in the bill processing device under the control of the control unit 1 as the control means. As a form of the notification, in addition to the display on the screen, lighting or blinking of the lamps, a buzzer or a voice may be used.

The control unit 1 as the control means is
When it is determined (by the control unit 1 serving as the determination unit) that skew or protrusion is present, the driving of the bundle conveying unit 6 by the drive device 6D is stopped and the abnormality notification is performed by the notification device 5. Is configured.

[Operation and Effect] Next, the operation and effect of the present embodiment having the above-mentioned configuration will be described.

First, in the loose banknote processing section P2, when the bundle conveying means 6 pulls out a bundle B'of loose banknotes from the stacking section 7 in the short side direction of the banknote, the pair of passage detection sensors 3a, 3
b detects the passage time of the bill edge at each position. Then, the control unit 1 as the determination unit determines whether or not the banknote is skewed based on the deviation between the passage times detected by the pair of passage detection sensors 3a and 3b.

Further, before the bundle B'of loose banknotes extracted from the stacking section 7 by the bundle conveying means 6 is conveyed to the bundled banknote processing section P1 in the banknote longitudinal direction, a pair of end detection sensors 4a, 4a,
Based on the presence / absence of the detection of the bill edge portion by 4b, the control unit 1 as the determination means determines whether or not the bill protrudes in the longitudinal direction.

As a result, when the loose banknotes stacked in the banknote stacking unit 7 are taken out as a bundle and conveyed,
It is possible to provide a low-cost bill processing device that accurately detects the protrusion of a bill in the longitudinal direction.

Here, the following inconveniences may occur only by detecting the bill edge portions by the pair of edge detection sensors 4a and 4b as described above. That is, when a pair of end detection sensors 4a and 4b are arranged corresponding to the length of a banknote of a certain denomination (for example, a 10,000-yen banknote), a banknote of a denomination having a shorter length (for example, A slight protrusion of one thousand yen bill will not be detected.

Therefore, in the present embodiment, when the bundle conveying means 6 conveys the bills in the longitudinal direction, the passage time of the bundle is measured by the control unit 1 as a time measuring means. Then, by comparing the measured passage time with the reference passage time stored in the storage unit 2, the control unit 1 as the determination unit determines whether or not the banknote is protruding in the longitudinal direction. This makes it possible to avoid the inconveniences described above and perform a more rigorous determination regardless of the difference in the length of the banknote depending on the denomination.

Further, when the banknote is skewed or sticks out, the control section 1 as the control means stops the driving of the bundle conveying means 6 and notifies the abnormality by the notifying device 5, so that the banknote processing thereafter. It is possible to take prompt action without affecting the.

[Modification] In the above embodiment, the case where the pair of passage detection sensors 3a and 3b detect the skew of the bill has been described.
It is also possible to detect the protrusion of the bill in the lateral direction by a and 3b. For example, similarly to the case of the protrusion detection based on the passage time in the banknote longitudinal direction described above, detection of the passage detection sensors 3a and 3b from the start of extraction of the bundle B ′ of loose banknotes from the stacking unit 7 by the bundle conveying unit 6. It is also possible to detect the protrusion of the bill in the lateral direction based on the elapsed time until the passage of the bill edge portion.

According to the first aspect of the present invention, when the bundle conveying means pulls out a bundle of loose banknotes from the stacking portion in the banknote transverse direction, the pair of passage detecting means are arranged at the respective positions of the banknote end portion. Detect the time of passage. Then, the determination unit determines whether or not the banknote is skewed based on the deviation between the passage times detected by the pair of passage detection units. This makes it possible to provide a low-cost banknote processing device that accurately detects skew of banknotes when a bundle of loose banknotes stacked in the banknote stacking unit is extracted and conveyed.

According to the second aspect of the present invention, before the bundle of loose banknotes extracted from the stacking section by the bundle conveying means is conveyed in the longitudinal direction of the banknote, the presence or absence of the detection of the banknote edges by the pair of edge detecting means is detected. Based on the above, the determination means determines whether or not there is a protrusion in the longitudinal direction of the bill. Accordingly, it is possible to provide a low-cost banknote processing device that accurately detects the protrusion of the banknotes in the longitudinal direction when the banknotes stacked in the banknote stacking unit are extracted and conveyed as a bundle.
