Description

  The present invention relates to a bill handling apparatus.

Some banknote handling apparatuses have a banknote feeding mechanism including a banknote stacking unit and a conveyance path connected to the banknote stacking unit. In the banknote feeding mechanism, banknotes are separated from the banknote stacking unit one by one and fed out to the transport path. If a conveyance abnormality occurs due to a poor conveyance posture of the separated banknotes while performing the banknote separation operation, the banknote separation operation is stopped, and a part of the banknotes in the middle of separation is transferred from the banknote stacking part to the transport path. There is a case where it protrudes or remains in the conveyance path in the feeding mechanism.
Patent Document 1 describes that a banknote in such a state is returned to the banknote stacking unit by operating either or both of the banknote feeding mechanism and the conveyance path in the counter-feeding direction.

The banknote handling apparatus 100 accommodates a banknote identification section 170, a banknote storage section 200, and the like, which will be described later, in a casing section 112 that is closed by a safe door 113 to ensure security.

  Further, the deposit / withdrawal mechanism unit 116 includes an operation panel 118 operated by a counter attendant, and a deposit unit 120 and a withdrawal unit 140, which will be described later, are arranged on the upper surface from the front side of the page in FIG. A withdrawal part 140 and a deposit part 120 are provided adjacent to each other in order from the front side to the rear side.

  In addition, as shown in FIG. 2, the bill handling apparatus 100 is configured such that the customer reception table D covers the rear side of the apparatus and the customer K can visually recognize the depositing unit 120 and the dispensing unit 140 of the depositing / dispensing mechanism unit 116. It is said.

  The state of visual recognition by the customer K is shown in FIG. 3, and the banknote handling apparatus 100 connects the depositing unit 120 and the dispensing unit 140 in this order from the customer K side to the depositing / dispensing mechanism unit 116. Prepare. Thus, the customer K can easily insert the bill into the depositing unit 120.

  As shown in FIG. 2, the counter clerk M faces the customer K across the customer reception table D, and in addition to a predetermined operation of the operation panel 118, the banknote B deposited from the customer K is input to the depositing unit 120. And banknotes withdrawn to the withdrawal unit 140 are delivered to the customer K. Hereinafter, the configuration of the bill handling apparatus 100 will be described in detail.

  FIG. 4 is a cross-sectional view schematically showing the internal configuration of the banknote handling apparatus 100 and the banknote transport path. As shown in the figure, the banknote handling apparatus 100 includes a depositing / dispensing mechanism unit 116 that includes the depositing unit 120 that accepts depositing the banknote B and the withdrawal unit 140 that dispenses the banknote B adjacent to each other.

  The banknote recognition unit 170 and the banknote storage unit 200 accommodated in the safe 110 are partitioned from the depositing unit 120 and the withdrawal unit 140 of the deposit / withdrawal mechanism unit 116 by the housing unit 112. 170 is located above the banknote storage unit 200.

  Further, as shown in FIG. 3, the depositing unit 120 is arranged on the banknote recognition unit 170 side, that is, the rear side with respect to the dispensing unit 140, and the dispensing unit 140 arranged adjacent to the depositing unit 120 is arranged in the depositing unit 120. The wall 141 is provided on the side. The wall 141 covers the inside of the dispensing unit 140 on the depositing unit 120 side, and includes a base 141B at the upper end thereof with a lid 141c therebetween.

The lid 141c is openable and closable so as to cover the upper end of the opening of the withdrawal unit 140, and prevents the withdrawal of the withdrawal banknotes conveyed to the withdrawal unit 140. The wall 141 extends only to the upper end of the opening of the depositing unit 120, and the width of the wall 141 is narrowed even in the lid 141c.
Therefore, the wall 141 and the lid 141c do not block the line of sight when the customer K (see FIG. 2) across the customer reception table D views the dispensing unit 140 from the depositing unit 120 side.

  In addition, since the lid 141c is not shaped to cover the entire dispensing unit 140, its width is narrow and it is provided near the center position, the flow line of the hand of the counter clerk M (see FIG. 2) Since it does not hinder the insertion of the bill B into the depositing unit 120, the operability is good.

  The bill identifying unit 170 forms a partial path of a first main transport path 183 (see FIG. 6) described later formed by the transport mechanism section 180. In other words, the first main transport path 183 passes through the banknote recognition unit 170. And this banknote identification part 170 is conveyed by the 1st main conveyance path | route 183 in the process of depositing / withdrawing, in addition to the money type classification of the banknote B, a serial number, banknote authenticity, damage status (rejection necessity). The bill B is identified.

  The banknote recognition by the banknote recognition unit 170 can be performed using various information such as image data obtained by scanning the banknote B, uneven shape of the surface of the banknote B, magnetic characteristics, optical characteristics with respect to ultraviolet rays, and the like. . The identification result of the banknote identification unit 170 is output to the control unit 300 described later, and is used for determination of a cassette for banknote conveyance, rejection conveyance, and the like.

  The transport mechanism unit 180 corresponding to the transport unit hangs from the depositing unit 120 and the dispensing unit 140 to the banknote storage unit 200 to form a banknote depositing path 180IN and a banknote dispensing path 180OUT. Although details of both the paths will be described later, as shown in FIG. 4, the banknote deposit path 180IN includes an upstream deposit path 181 from the deposit section 120 to the banknote identification section 170.

  The banknote withdrawal path 180OUT includes a downstream side withdrawal path 186 from the banknote identification section 170 to the withdrawal section 140. The conveyance mechanism part 180 which has these paths connects the deposit part 120 and the withdrawal part 140 to the banknote identification part 170 and the banknote storage part 200 by the above-mentioned deposit / withdrawal path, and conveys a banknote. The banknote storage unit 200 includes banknote storage cassettes 201 to 205, and stores the banknote B in each cassette as described later.

Next, an electrical configuration according to an embodiment of the present invention will be described.
First, FIG. 5 is an explanatory diagram showing a control block of the bill handling apparatus 100. The banknote handling apparatus 100 includes a depositing unit 120, a dispensing unit 140, banknote storage cassettes 201 to 205 of the banknote storage unit 200, a banknote identification unit 170, an operation panel 118, and a transport mechanism as electrical function blocks. Unit 180 and control unit 300.

  As will be described later, the transport mechanism unit 180 includes a gate group including a gate 201b for each cassette, a detection sensor group of a plurality of detection sensors 188 installed in the banknote transport path, and a plurality of drive motors 189 responsible for banknote transport. A drive motor group.

  The control unit 300 includes a main control unit 301, a memory 302, and an upper communication unit 303 that can communicate with the operation terminal P. The main control unit 301 is mainly composed of a control microprocessor. The main control unit 301 controls the gate group and the drive motor group of the transport mechanism unit 180 in addition to the banknote delivery / conveyance included in the depositing unit 120 and the dispensing unit 140 in accordance with the banknote depositing / dispensing conveyance. Drive control.

  The detection sensor 188 included in the detection sensor group detects the banknote conveyance state in a banknote deposit path 180IN and a banknote withdrawal path 180OUT, which will be described later, and whether or not banknotes are present in the deposit section 120 and the withdrawal section 140, the banknote storage cassette 201- The number of bills stored in 205 is detected, and the detection signal is output to the controller 300.

Next, the deposit conveyance process will be described with reference to FIG.
As shown in FIG. 6, the banknote depositing path 180IN extends from the depositing unit 120 and reaches the banknote identifying unit 170 via the housing unit 112. Thereafter, the banknote depositing path 180IN is turned back by a direction changing roller 180r downstream of the banknote recognition unit 170, and extends to the banknote storage cassette 205 along a sequence of the cassettes of the banknote storage unit 200 positioned below the banknote recognition unit 170. .

  The banknote depositing path 180IN having such a path trajectory is defined as an upstream depositing path 181 from the depositing unit 120 to the banknote identifying unit 170, and a path downstream from the path is a downstream depositing path 182. The conveyance mechanism unit 180 passes the bank-side depositing path 182 through the banknote recognition unit 170 and extends to the direction changing roller 180r, and is turned back by the direction changing roller 180r and extends in the horizontal direction to extend the banknote storage unit. It forms with the 2nd main conveyance path | route 184 which reaches the banknote storage cassette 205 of 200.

  And the conveyance mechanism part 180 deposits and conveys the banknote B thrown into the deposit part 120 along the path | route of the banknote deposit path | route 180IN mentioned above, and according to the identification result of the banknote identification part 170, banknote storage cassette 201-205. Transfer money to either of these.

Next, banknote delivery from the depositing unit 120 will be described with reference to FIGS. 7 and 8.
FIG. 7 is an explanatory view schematically showing a roller configuration related to banknote delivery in the depositing unit 120, and FIG. 8 is a schematic diagram of a main roller configuration involved in banknote delivery from the depositing unit 120 to the upstream depositing path 181. FIG.

  As shown in the drawing, the depositing unit 120 includes an opening recess 121 whose upper end is opened. The opening recess 121 accumulates and holds the banknote B to be fed out on the inclined bottom wall, and surrounds the banknote B with the side wall 122 and the banknote end side wall 123 around the recess. In addition, the depositing unit 120 forms a delivery path part 124 by the lower end of the banknote end side wall 123 and the inclined bottom wall of the opening recess 121, and the delivery path part 124 serves as an upstream depositing path at the bottom corner. 181 (see FIG. 6).

  The depositing unit 120 includes a plurality of banknote delivery first rollers 125, a banknote delivery second roller 126, and a banknote delivery third roller 127 on the inclined bottom wall of the opening recess 121. Each of these delivery rollers rotates with the roller peripheral wall protruding from the inclined bottom surface of the opening recess 121.

  The depositing unit 120 rotationally drives each of the above-described delivery rollers in the direction of the arrow shown in FIG. 8, so that the banknotes B accumulated in the opening recesses 121 are extended from the banknotes B on the deposition lower side to the delivery path unit 124. In this case, the sheets are sent one by one to the upstream-side deposit path 181 (see FIG. 6) connected thereto.

  Since the banknote sending first roller 125 has a radius of a part of the outer peripheral arc larger than the radius of the other arc portion, the banknote B that has been deposited in the opening recess 121 is moved up and down from the banknote B on the lower side of the stack. It sends out to the delivery path section 124.

  In addition, the money_receiving | payment part 120 is equipped with the perfect circle-shaped banknote sending 1st auxiliary roller 125a along with the banknote sending 1st roller 125, as shown in FIG. In addition, the depositing unit 120 includes an impeller 128 on the lower end side of the banknote end side wall 123. As shown in FIG. 7, a plurality of the impellers 128 are arranged on the banknote end side wall 123, and the tip of the blade 129 protrudes from the opening 123 h of the banknote end side wall 123 into the opening recess 121.

  The protruding blade | wing 129 can contact with the banknote B hold | maintained at the opening recessed part 121. FIG. The impeller 128 is rotated and driven when the bill B is sent out from the depositing unit 120 under the control of the control unit 300 described later, and the plurality of blades 129 are formed in detail on the lower bill B accumulated in the opening recess 121. Is brought into contact with the end side of the bill B.

  In this embodiment, since the impeller 128 is rotated in the banknote storage direction (arrow direction in FIG. 8) to the banknote handling apparatus 100, the blade 129 is placed on the end of the lower banknote B accumulated in the opening recess 121. The blade 129 is put in contact from the upper side to the lower side of the banknote accumulation.

  Therefore, the banknotes B accumulated in the opening recess 121 are sequentially sent out one by one from the banknotes B on the lower side of the stack by rotation of the delivery rollers including the banknote delivery first roller 125 and end contact of the blades 129. It is sent to the route section 124.

  When sending banknotes, there may be a case where one banknote B is received in the opening recess 121 or a case where the uppermost banknote B of the stacked banknotes remains. When one banknote B or several banknotes B are bent as shown in the figure and are not in contact with the banknote delivery first roller 125 and the banknote delivery roller 126, the banknote B has its banknote tip on the banknote end side wall 123. It is possible to take a stop posture while being in contact with the outer surface and stay in the opening recess 121.

Since the depositing unit 120 of the present embodiment brings the blade 129 into contact with the banknote edge of the banknote B in such a stopped position as described above, the banknote B changes its position from the stopped position, and the banknote edge The portion is pressed against the bottom corner side of the opening recess 121.
As a result, the banknote B that has not been in contact with the delivery roller because it has been in the stop posture until then comes into contact with either or both of the banknote delivery first roller 125 and the banknote delivery second roller 126.

  Next, with reference to FIG. 9, FIG. 10, FIG. 11, FIG. 12, and FIG.

  FIG. 9 is an explanatory view showing a state in which a part of the banknote Br is protruded from the opening recess 121 to the delivery path portion 124 when the feeding is stopped while being fed out from the opening recess 121 to the delivery path portion 124.

  FIG. 10 is a diagram showing a state in which the return bill Br partially protruding from the opening recess 121 to the delivery path portion 124 is returned to a position where it is not detected by the bill remaining detection sensor 501 by the reverse rotation of the bill delivery first roller 125. It is.

  FIG. 11 shows a state in which the return bill Br pops out of the opening recess 121 when the return bill Br is returned by rotating the bill delivery second roller 126 at a normal speed in a state where there is no banknote before separation in the opening recess 121. It is explanatory drawing.

  In FIG. 12, when the banknote sending second roller 126 is rotated at a low speed and the banknote is returned in a state where the banknote B before separation is present in the opening recess 121, the return banknote Br returns the banknote B before separation of the opening recess 121 in the return direction. It is explanatory drawing which shows the state taken out.

  FIG. 13 is an explanatory diagram illustrating a control flow in the case of performing banknote return in an intermittent operation with the configuration of the embodiment.

  Hereinafter, the operation of banknote return and the effect will be described in the order of the control flow of FIG. In the following description, the opening recess 121 serves as a bill depositing unit, a delivery path unit 124 serves as a conveyance path, and a bill delivery second roller 126 serves as a drive unit and a bill feeding mechanism for driving the conveyance path. Respectively.

  When banknote return is started from the state of FIG. 9, first, banknote return start (S1301) is called. Next, the presence / absence of banknotes is confirmed by the banknote remaining detection sensor 501 provided in the delivery path section 124 in FIG. 9 (S1302).

  If a banknote is detected at this time, the banknote delivery second roller 126 is referred to as the direction of the depositing unit 120 (the arrow direction of the banknote delivery second roller 126 in FIG. 9; hereinafter referred to as “return direction”). ) Until the trailing edge of the banknote is detected by the banknote remaining detection sensor 501, that is, until no banknote is detected (S1304), the banknote delivery second roller 126 is rotated in the return direction. to continue. Thereafter, the bill delivery second roller 126 is stopped (S1305).

  At this time, part of the return banknote Br is in a state of being sandwiched by the delivery path portion 124, so there is no fear of popping out. Therefore, there is no problem even if the rotation speed of the banknote delivery second roller 126 is a speed at which banknotes pop out. It is assumed that the first banknote delivery roller 125 does not rotate while the second banknote delivery roller 126 rotates in the return direction. If no banknote is detected, the operation proceeds to the next operation without performing the above-described operation.

  As a result of the above operation, the delivery path section 124 is in a state where the return banknote Br may remain between the banknote residual detection sensor 501 and the opening recess delivery path boundary 130 as shown in FIG.

  In the configuration of this embodiment, since there is no banknote detection sensor at the opening recess delivery path boundary 130, when the banknote delivery second roller 126 is rotated in the return direction from the state of FIG. 10, the return banknote Br is released into the opening recess 121. I can't know the exact timing that will be done.

  Therefore, when the conveyance speed at the time of discharge | emissioning the return banknote Br to the opening recessed part 121 has not fully decelerated, as shown in FIG. 11, the return banknote Bring out the opening recessed part 121 without decelerating, and a banknote is scattered or lost. May occur.

  Moreover, when the banknote sending second roller 126 is rotated in the return direction at a speed at which the banknote does not pop out, and the pre-separation banknote exists in the opening recess 121, the return banknote Br returns the pre-separation banknote as shown in FIG. It will be taken out in the direction, and the alignment of banknotes before separation will be greatly impaired. And if separation is started in a state where the alignment of the banknotes before separation is broken, the posture of the banknotes taken into the delivery path portion 124 deteriorates, and the probability of causing a conveyance failure at the time of separation increases.

  In order to solve the above-described problem, in this embodiment, an intermittent operation that repeats the rotation of the banknote delivery second roller 126 in the returning direction and the stop for a predetermined time by the operation following (S1306) in FIG. Return the banknote at. The banknote return in the intermittent operation is performed in such a manner that a set of rotation of the banknote delivery second roller 126 in the return direction by a predetermined rotation amount and stop for a predetermined time is regarded as one cycle, and this cycle is repeated.

  Further, the amount of bill return by intermittent operation is such that the bill delivery second roller 126 is rotated in the reverse direction and the bill transport distance is the distance from the bill remaining detection sensor 501 on the delivery path portion 124 to the connection point with the opening recess 121. Do so as to exceed the distance between. Thereby, it is possible to prevent the return banknote Br from remaining in the delivery path section 124 and to reliably return the banknote to the depositing section 120.

  First, the monitoring of the rotation amount of the banknote delivery second roller 126 is started so that the distance of the reverse rotation of the banknote delivery second roller 126 can be measured during the intermittent operation (S1306).

  For monitoring the amount of rotation, various methods can be applied, such as measuring the pulse amount of a rotating object, measuring the time of rotation driving, or measuring the movement distance of a banknote by rotation. It is.

Next, after rotating the banknote delivery second roller 126 in the return direction (S1307), monitoring of the rotation amount of the banknote delivery second roller 126 in one cycle during the intermittent operation is started (S1308).
In the configuration of this embodiment, since there is no mechanism for fixing the pre-separation banknote B present in the opening recess 121, the pre-separation banknote B moves in the direction opposite to the separation direction.

  Therefore, in order to return the banknote while sliding the pre-separation banknote B and the return banknote Br, it is necessary to satisfy a condition that the banknotes start to slide at the moment when the return banknote Br starts to move. In order for the bills to begin to slip, the return bill Br is accelerated at a certain acceleration or more so that the inertial force acting on the pre-separation bill B exceeds the static friction force acting between the pre-separation bill B and the return bill Br. It is necessary to switch the friction from static friction to dynamic friction.

  Further, when accelerating while maintaining the above-described acceleration, the banknote needs to be stopped before the occurrence of the pop-out because the speed of the return bill Br pop-out occurs after a certain period of time has elapsed.

  As described above, the rotation of the banknote delivery second roller 126 in the intermittent operation ensures an acceleration that switches the friction between the banknotes from static friction to dynamic friction, and the rotation of the returning banknote Br does not reach the speed at which the banknotes pop out. The amount is required.

  It should be noted that the required acceleration increases as the number of pre-separation banknotes B decreases, and becomes maximum when the pre-separation banknote B is one. Regarding the amount of rotation, the amount of deceleration received by the return bill Br when there is no pre-separation bill B is minimized.

Next, monitoring is performed until the banknote delivery second roller 126 finishes rotating the rotation amount of one cycle described above (S1309). When a new banknote is detected by the banknote remaining detection sensor 501 during this monitoring (S1313), the process returns to A of FIG.
After the banknote delivery second roller 126 rotates in the specified rotation amount return direction, the rotation is stopped (S1310), and the elapsed time is waited for the time required to perform one cycle of rotation (hereinafter referred to as stop time) ( S1311).

  As for the stop time, a minimum time is ensured in which the return bill Br accelerated by the reverse rotation can be stopped completely. Further, in order to completely stop the return banknote Br, the return banknote itself has the complete stop of the banknote delivery second roller 126 and the deflection of the return banknote Br caused by the rotation of the banknote delivery second roller 126. It is necessary to secure time for returning to the original state by force.

  In addition, the time for returning the return bill Br to the original state depends on the material and state of the return bill Br or the force received by the return bill Br from the outside. If the magnitude | size of the force which return banknote Br receives from the outside and the magnitude | size of the elastic force which return banknote Br itself approaches, time for return banknote Br to return to the original state will become long. Therefore, you may set the stop time of the banknote sending 2nd roller 126 so that at least the time for returning the returned banknote Br to the original state may be exceeded.

  Next, it is confirmed whether or not the rotation amount rotated by the intermittent operation exceeds the distance between the bill remaining detection sensor 501 on the delivery path portion 124 and the opening recess delivery path boundary 130 (S1312). If the above conditions are satisfied, the banknote return ends (S1314). If not, the reverse rotation and stop of the banknote delivery second roller 126 are performed again (S1307).

  With the above operation, the banknote part of which protrudes from the depositing unit 120 to the delivery path unit 124 does not jump out of the depositing unit 120, and the return banknote Br does not take out the banknote before separation in the return direction. It becomes possible to return to 120.

[Example 2]
In the intermittent operation described in the first embodiment, the set of the rotation of the banknote delivery second roller 126 in the return direction of the predetermined rotation amount and the stop for a predetermined time is set as one cycle. A set of high-speed rotation and low-speed rotation in the return direction of the roller 126 for a predetermined time is defined as one cycle. When switching the speed, it is necessary to ensure an acceleration equal to or higher than the intermittent operation including the stop.

  Also in the present embodiment, the banknote partially protruding from the depositing unit 120 to the delivery path unit 124 is not ejected from the depositing unit 120, and the return banknote Br is deposited without taking out the banknote before separation in the return direction. It is possible to return to the unit 120.

  As described above, in the second embodiment, banknote return conveyance can be realized in a short time by performing control that combines high-speed rotation and low-speed rotation without stopping the banknote delivery second roller 126.

[Example 3]
In the intermittent operation described in the first embodiment, while the second banknote delivery roller 126 is rotating in the return direction, the first banknote delivery roller 125 is not rotated. The roller 125 is also rotated. Differences from the control flow and the first embodiment will be described below.

  FIG. 14 is an explanatory diagram showing a control flow in the case of performing the banknote return of the intermittent operation by synchronizing the rotation of the banknote delivery first roller 125 and the banknote delivery second roller 126 with respect to the configuration of the first embodiment. .

  In FIG. 14, the same operation is performed on the banknote delivery first roller 125 at the place where the acceleration / deceleration and stop of the banknote delivery second roller 126 are performed (S1404) (S1406) (S1410) (S1413). By doing so (S1403) (S1407) (S1409) (S1414), the banknote delivery first roller 125 and the banknote delivery second roller 126 are operated in synchronization.

  Also in the operation of the control flow in FIG. 14, the banknote partially protruding from the depositing unit 120 to the delivery path unit 124 does not jump out of the depositing unit 120, and the return banknote Bring out the banknote before separation in the return direction. It is possible to return to the depositing unit 120 without any trouble.

  Moreover, although the example which synchronizes the banknote delivery 1st roller 125 and the banknote delivery 2nd roller 126 was shown in FIG. 14, the method of making it operate | move at another timing, such as operating by fixed or indefinite time difference, is also considered.

  In the present embodiment, not only the banknote delivery first roller 125 but also the banknote delivery second roller 126 is rotated, and the banknote is conveyed while increasing the point for transmitting the driving force to the return banknote Br, so that the return banknote Br is separated. When inserted under the bill B, the return bill Br is prevented from being bent, and the bill can be conveyed to the depositing unit 120 in a good state.

Although the bill returning operation has been described above, the present embodiment has the following effects.
In the case where there is no bill decelerating mechanism at the separation source for returning the bills, it is possible to prevent the bills from popping out by suppressing the release speed of the return bill Br to the depositing unit 120, and to prevent the bills from being scattered or lost. Moreover, when the banknote before separation exists in the depositing unit 120 that is the separation source for returning the banknote and the banknote is returned while interfering with the banknote before separation and the return banknote Br, the return banknote Br is slipped with the banknote before separation. However, by performing the banknote return so as to interfere with each other, it is possible to suppress the deterioration of the posture of the banknote before separation due to the interference, and to prevent a conveyance failure from occurring during the separation after the banknote return.

  In addition, although this embodiment demonstrated the return operation | movement of the banknote conveyed from the money_receiving | payment part 120, a banknote return operation | movement can be applied also in the payment | withdrawal part 140, and the same effect can be acquired.

  As mentioned above, although the form for implementing this invention was demonstrated, this invention is not limited to these examples, A various structure and operation | movement are applicable in the range which does not change the meaning.
