  The present invention relates to a deposit / withdrawal reject mechanism that recognizes a banknote and rejects and returns a banknote that cannot be recognized.

  As shown in FIG. 8, generally, the banknote depositing / dispensing machine performs a depositing / dispensing unit 1 that performs a depositing / dispensing operation of a banknote from a customer and an operation of rejecting and returning a banknote that cannot be recognized, and a recognition of the inserted banknote. A recognition unit 2 is provided.

  Then, the deposit / withdrawal unit 1 is rejected without being recognized as a genuine bill by the pool unit 21 for pooling deposited banknotes, the banknote separating unit 22 for separating the deposited banknotes one by one, and the recognition unit 2. The deposit reject unit 3 is arranged to perform processing for collecting the banknotes and processing for returning the accumulated reject banknotes to the customer.

  Then, as shown in FIGS. 9 and 10, the deposit reject unit 3 includes an upper belt unit 6a composed of a conveying belt and a roller, a lower belt unit 6b provided in the lower portion, and a direction of the temporary stacking unit 5 ( It is comprised from the banknote stopper 8 for stopping the reject banknote conveyed from the arrow C direction in the figure, and the drive motor for driving each part which is not shown in figure.

  In the deposit reject unit 3 having the configuration shown in FIG. 9, during the depositing operation, the lower belt unit 6 b ′ and the conveyance guide 90 ′ shown by the broken line are moved in the direction of arrow A in the drawing by a driving device (not shown). The banknote stopper 8 'is moved in the B direction and closed at the position indicated by the solid line so that the banknote 100 that has been conveyed is stored in the accumulation area of the deposit reject unit 3. The banknotes 100 rejected are prevented from jumping out and accumulated in the space (9a) formed by the movement of the lower belt portion 6b.

  Also, during the operation of returning the reject banknote 100, the lower belt portion 6b and the conveyance guide 90 are configured as a conveyance path, contrary to the above, and are moved and closed in the opposite direction to the A direction in the figure. The reject banknote 100 is clamped, and the banknote stopper 8 is moved in the opposite direction to the B direction in the drawing to be in an open state, and the reject banknote 100 is conveyed to the deposit / withdrawal unit 1 and returned to the customer.

  In the deposit reject unit having the configuration shown in FIG. 10, during the depositing operation, the lower belt portion 6b 'and the conveyance guide 90' which are broken lines are rotated around the roller 7 as a fulcrum and moved in the D direction to be arranged at the solid line positions. Then, the banknote stopper 8 'is moved in the B direction and placed at the position of the solid line and closed, and the rejected banknote 100 conveyed is prevented from jumping out of the stacking space, and the lower belt portion 6b. The rejected banknotes 100 are accumulated in the space (9b) created by the movement of the.

  Further, during the operation of returning the reject banknote 100, the lower belt portion 6b and the transport guide 90 are configured as a high-speed transport path, so that the banknote 100 is clamped while being moved and closed in the opposite direction to the D direction.

At this time, generally, the rejected banknotes may be cut or folded, and may be difficult to transport. Therefore, an L-shaped lever (not shown) is provided as a forced discharge mechanism so as to reciprocate, making it difficult to transport. The banknotes accumulated in the state are pushed out to the deposit / withdrawal unit 1 so as not to remain in the deposit / rejection reject unit 3.
JP 2003-226442 A

  However, in the case of the conventional deposit reject unit mechanism, when the frictional force between the upper belt portion 6a and the lower belt portion 6b and the banknote cannot be increased and there is no forced discharge mechanism, the deposit / withdrawal portion 1 is provided. There was a problem that bills could not be transported completely.

  Even when a lever is provided as a forcible discharge mechanism, the lever reciprocates when a bill is sandwiched between the lever movable part and the like. There was a problem that the banknote was not pushed out and the banknote was pulled back, and the banknote was left in the deposit reject part 3 or only a part of the banknote to be returned was damaged.

  The present invention employs the following configuration in order to solve the above-described problems. That is, in a medium processing machine having a rejection mechanism that recognizes banknotes and rejects and carries out unrecognizable banknotes, a protrusion is provided on the reject medium transport belt, and the reject medium is scraped out by the protrusions.

  According to the banknote depositing / dispensing machine of the present invention, since the protrusion is provided on the belt for transporting the reject medium and the reject medium is scraped out by the protrusion, the reject banknote accumulated in the deposit rejecting part can be pulled back. Since it can be scraped out even if the bill is broken or torn, it can be reliably returned to the customer as it is.

  Embodiments of the present invention will be described below with reference to the drawings. In the following description, for convenience, the medium to be handled will be described as a banknote. However, if it is a paper sheet-like medium, it can be handled in the same manner even if it is not a banknote but a bond or a ticket.

  In the banknote depositing / dispensing machine according to the first embodiment, a protrusion is provided on the upper belt portion of the deposit reject unit 3, and banknotes accumulated in the deposit reject unit are pushed out by the projection.

(Constitution)
(Configuration of the entire device)
As shown in FIG. 8, the entire configuration of the banknote depositing / dispensing machine according to the first embodiment includes a depositing / dispensing unit 1 that performs an operation of separating a banknote from a customer, an operation of returning an unrecognizable banknote, and the like. Recognizing unit 2 that recognizes banknotes, temporary stacking unit 5 that temporarily stacks banknotes that have been made correct by the recognizing unit 2, and stacking unit 10 that recognizes the banknotes of the temporary stacking unit 5 again and stacks them for each banknote. And a replenishing unit 11 for replenishing banknotes and a reject unit 12 for storing banknotes to be collected as reject banknotes.

  Then, the deposit / withdrawal unit 1 is rejected without being determined as a correct bill by the pool unit 21 for pooling deposited banknotes, the banknote separating unit 22 for separating deposited banknotes one by one, and the recognition unit 2. It is comprised from the deposit | rejection rejection part 3 which performs the process which collects a banknote without taking in in an apparatus, and the process which returns the accumulated reject banknote to a customer.

  As shown in FIG. 3, the pool unit 21 separates the received banknotes when a customer inserts banknotes or removes rejected banknotes by a drive motor or the like (not shown). In the case of recognizing (FIG. 3B), the position can be changed.

(Structure of the deposit rejection unit)
The configuration of the deposit reject unit 3 will be described in detail below with reference to FIG. First, the structure of the deposit rejection unit 3 will be described with reference to the lower lateral view (FIG. 1B). A conveyance guide 90 similar to that of the conventional deposit reject unit described with reference to FIGS. 9 and 10 is provided below the flat belt 25 and the protruding belt 26, but is omitted because it is complicated.

  The deposit reject unit 3 includes an operation of accumulating reject banknotes, a lower belt unit 24a that switches between an open state and a closed state according to an operation of returning and withdrawing, an open guide 24b as a guide for opening and closing the lower belt unit 24a, 2 shows a bill stopper 38 that operates in synchronism with the operation of the belt portion 24a, a flat belt 25 for transporting bills to the depositing portion 1, and a protrusion 50 for pushing out the accumulated bills. The protruding belt 26, a driving gear 36 driven by a motor (not shown), a joint gear L (27L) for transmitting driving to the lower belt portion 24a and the flat belt 25, and a joint for transmitting driving to the protruding belt 26 The cam 29 for switching the position of the gear U (27U), the open guide 24b, etc. according to each operation mode, and the movement of the cam 29 Link had fulcrum 41 to reach A (30a), are provided with a link B (30b).

  The link A (30a) is interlocked with the bill stopper 38, and the cam 29 is composed of two cams 29a and 29b, both of which rotate in conjunction with each other. .

  Next, the configuration of the deposit reject unit 3 will be described with reference to a top view (FIG. 1A). The deposit reject unit 3 is further provided with a projection position detection mechanism 37 that detects the position of the projection 50 of the projection belt 26. When the protrusion belt 26 rotates in the arrow K direction, the protrusion position detection mechanism 37 rotates in the arrow M direction with the fulcrum 42 as a fulcrum when the protrusion 50 moves in the arrow K direction and hits the protrusion position detection mechanism 37. . Then, by detecting this rotation by an optical sensor or the like provided at the tip of the protrusion position detection mechanism 37, it is possible to detect that the protrusion 50 has reached a predetermined position.

  The relationship between the two shafts 32, 33 arranged on the left and right and the belt pulley is that the two belt pulleys 34 a, 34 b on the left side of the flat belt 25 and the belt pulley 34 c on the right side of the protruding belt 26 are idle and the right side of the flat belt 25. The two belt pulleys 35a and 35b and the belt pulley 35c on the left side of the protruding belt 26 are fixed.

  That is, when the rotational drive is transmitted to the right shaft 32, the flat belt 25 rotates but the protruding belt 26 does not rotate. When the rotational drive is transmitted to the shaft 33, the protruding belt 26 rotates but the flat belt is rotated. 25 has a structure which does not rotate.

  Further, in order to simplify the mechanism by placing the flat belt 25 and the protruding belt 26 on the same shafts 32 and 33 and arranging them in parallel, the flat belt 25 and the protruding belt 26 are arranged as shown in FIG. I am doing so.

  That is, the belt pulley diameter φ of the flat belt 25 and the protruding belt 26 is set to a pulley diameter that does not appear in the conveyance path area 39 except for the protruding portion 50 of the protruding belt 26. By adopting such a structure, when the depositing operation such as deposit payment is performed, if only the protruding portion 50 is out of the conveying path, only the flat belt 25 is rotated and the bill is conveyed without rotating the protruding belt 26. can do.

(Operation)
With the above configuration, the banknote depositing and dispensing machine according to the first embodiment operates as follows.
(Operation of the entire device)
First, the schematic operation of the entire banknote depositing and dispensing machine according to the first embodiment will be described with reference to FIG. When the customer inserts banknotes into the pool unit 21 of the depositing / dispensing unit 1, as the depositing operation, the banknote separating unit 22 separates the banknotes one by one and recognizes them by the recognizing unit 2. The banknotes that have been accumulated and rejected without being determined to be correct are accumulated in the deposit reject unit 3 as a deposit reject banknote stacking operation.

  Since the deposit reject banknotes accumulated in the deposit reject unit 3 are banknotes to be returned to the customer, the deposit reject banknotes are returned to the deposit / withdrawal unit 1 and returned to the customer as a deposit reject banknote carrying-out operation. At this time, when the number of deposits is equal to or greater than the prescribed number, banknotes exceeding the prescribed number are not separated / recognized but are left in the deposit / withdrawal unit 1 and returned to the customer as they are.

  The banknotes that have been regarded as regular bills and accumulated in the temporary stacking unit 5 are recognized again by the recognition unit 2 and stored in the stacking unit 10 for each type. At this time, when a recognition reject occurs, the banknote is stored in the reject unit 12. Further, when the amount of the banknote in the banknote depositing / dispensing machine becomes equal to or less than a predetermined amount, the banknote is replenished from the replenishing unit 11.

(Operation of the deposit rejection unit)
Next, the operation of the deposit reject unit will be described in detail with reference to the operation explanatory diagram of the deposit reject unit in FIG. 1, the operation explanatory diagram of the deposit / withdrawal unit in FIG. 3, and the operation table of the deposit reject unit 3 in FIG. First, when a customer inserts banknotes into the pool part 21, the pool part 21 turns to the separating part 22 side (in the direction of the arrow CCW in the figure) with the fulcrum (21b) as a fulcrum, and the position shown in FIG. After turning to the position shown in FIG. 3B, the banknotes are separated one by one.

  The banknotes are separated by a method of separating the pressed lower banknotes by the separating roller 22a of the banknote separating unit 22 while pressing the received banknotes downward by the bill press 21a. The separated banknote is conveyed to the recognition unit 2 in the arrow N direction in the figure.

(Payment reject banknote accumulation operation: mode number 1 in FIG. 5)
Then, as the deposit reject banknote stacking operation (mode number 1 in FIG. 5), the separated banknotes are conveyed to the recognition unit 2 and recognized. The banknotes thus collected are accumulated as reject banknotes in the deposit reject unit 3. At this time, assuming that the rotational position of the cam 29 is the position shown in the lateral view of FIG. 1B, the positions of the respective parts are illustrated by the links A (30a) and B (30b). That is, since the open guide 24b acts in the direction opposite to the arrow J, the lower belt portion 24a is in an open state, the bill stopper 38 is rotated in the direction opposite to the arrow I direction in the figure and closed, and the joint gear U (27U) rotates in the H direction and is not jointed, and the joint gear L (27L) is not jointed due to the lowering of the open guide 24b, and the shafts 32 and 33 are not driven. 25 and the protruding belt 26 are not rotated.

  As described above, all the received banknotes or a specified number are separated and recognized, and in the case of a correct note, they are accumulated in the temporary stacking unit 5, and rejected banknotes that are determined not to be correct are opened in the lower belt portion 24a. Accumulated in the left space.

(Deposit reject banknote return operation: mode number 2 in FIG. 5)
Then, when the separation and recognition of all the banknotes received or the prescribed number are completed, the banknotes are transferred to the rejected banknote (mode number 2 in FIG. 5), and in the state shown in FIG. The tip is raised to the upper part of the deposit reject unit 3.

  When the cam 29 is rotated in the CCW direction from the illustrated position by a drive motor (not illustrated) or the like (returning to FIG. 1), the contact positions of the cams 29a and 29b are rotated in the arrow F direction, and the link A ( 30a), the link B (30b) is also rotated in the F direction, thereby raising the open guide 24b and closing the lower belt portion 24a, and rotating the bill stopper 38 in the I direction to be in an opened state. Further, the joint gear U and the joint gear L (27U, 27L) are jointed to drive the flat belt 25 and the protruding belt 26 to convey the deposit reject banknote to the deposit / withdrawal unit 1.

  When the transfer of the deposit reject banknote to the deposit / withdrawal unit 1 is completed, the bill press 21a of the pool unit 21 is lowered to press the deposit reject banknote from above, and then the pool unit 21 is separated from the fulcrum 21b. Rotate in the opposite direction (CW direction) from the position of FIG. 3 (b) to the position of FIG. 3 (a), and the bill press 21a is opened to display a message or display prompting the customer to return.

(Withdrawal operation: mode number 3 in FIG. 5)
As a withdrawal operation (mode number 3 in FIG. 5) such as withdrawal of deposits, in the operation of paying a customer the banknotes accumulated in the accumulating unit 10 as a genuine note, the cam 29 is moved from the illustrated position to the CW direction by a drive motor or the like not illustrated , The contact position of the cam 29a moves in the direction of the arrow F and the contact position of the cam 29b does not move. Therefore, the link A (30a) moves in the F direction and the position of the link B (30b) remains unchanged. Therefore, the open guide 24b is raised in the direction of arrow J in FIG. 1 to close the lower belt portion 24a, and is opened by turning the bill stopper 38 in the direction of arrow I in the drawing, and the joint gear L (27L). Only the right belt 32 is driven, and only the flat belt 25 is driven.

  The reason why the joint gear U (27U) is not joined, the left shaft 33 is not driven, and the protruding belt 26 is not driven is that the protruding portion 50 of the protruding belt 26 passes through the conveyance path during the dispensing operation. This is because the protrusion 50 needs to be stopped and placed at a position outside the conveyance path because it collides with the bill and causes jamming. The stop position of the protrusion 50 may be detected by the protrusion position detection mechanism 37 and stopped at a predetermined position outside the conveyance path.

  In the above description of the embodiment, an example in which two flat belts 25 and one protruding belt 26 are provided as shown in the top view of FIG. 1A has been described. However, as shown in FIG. In addition, by adopting a configuration in which three flat belts 25 and two protruding belts 26 are provided, a small banknote can be reliably returned to the customer as in the case where a plurality of remaining banknotes are folded.

  Of course, the number of the flat belts 25 and the protruding belts 26 may be increased or decreased, or the flat belts 25 and the protruding belts 26 are slid in the directions of the shafts 32 and 33 in relation to the rotation of the belts. Such a mechanism may be used.

(Effect of Example 1)
As described above in detail, according to the banknote depositing / dispensing machine of Example 1 as described above, the protrusion is provided on the belt for transporting the reject medium, and the reject medium is scraped out by the protrusion. Since the reject banknotes accumulated in the reject unit can be scraped out without being pulled back, even banknotes that are broken or torn can be reliably returned to the customer as they are.

  In addition, by providing a cam having two independent cam surfaces and controlling the rotation, at least the deposit reject banknote accumulation operation, the deposit reject banknote carry-out operation, and the withdrawal operation can be realized, so that the mechanism can be simplified and the actuator The number of can also be reduced.

  The banknote depositing / dispensing machine according to the second embodiment provides a range in which the conveyance upstream side housing of the deposit rejection unit and the protrusion tip locus overlap, and a range in which the conveyance downstream end extension line of the conveyance guide and the protrusion tip locus overlap. Is provided.

(Constitution)
FIG. 7 is a diagram illustrating the configuration and operation of the banknote depositing / dispensing machine according to the second embodiment. Since each configuration is the same as the configuration of the deposit reject unit of the first embodiment, description thereof is omitted for the sake of brevity. The deposit reject unit of the second embodiment is characterized by its arrangement, and is different from the deposit reject unit of the first embodiment.

  FIG. 7A is a view showing the arrangement of each part when collecting reject banknotes in the deposit reject part 3 when depositing, and the lower belt part 24a is opened to generate a space for collecting reject banknotes. It is in the state. A broken line portion 101 in the figure represents the locus of the leading end drawn by the rotation of the belt by the leading end of the protruding portion 50 of the protruding belt 26.

  On the left side of the figure, a housing 40 of the deposit reject unit 3 for stacking banknotes is provided, and banknotes conveyed from the direction of the temporary stacking unit 5 are dropped by this housing 40 to the lower belt portion 24a. And accumulated. The jam banknote 100z shows that the banknotes conveyed from the direction of the temporary stacking unit 5 are stacked in a state of being distorted due to a jam or the like. Note that the flat belt 25 and the banknote stopper 38 are omitted because the drawing becomes complicated.

  FIG. 7B is a diagram illustrating the positions of the respective parts when the lower belt part 24 a is closed and the accumulated reject banknotes are conveyed to the pool part 21. Also in this figure, the broken line portion 101 represents the tip locus of the protrusion of the protrusion belt 26. In addition, Lx in the figure indicates a range where the deposit rejection unit housing 40 on the upstream side of the transport and the protrusion tip locus 101 overlap, while Ly indicates an extension line on the right end on the downstream side of the transport guide 90. A range where 102 and the protrusion tip locus 101 overlap is shown.

  As shown in FIG. 7B, the deposit reject unit of the second embodiment is such that both Lx and Ly are 0 or more.

(Operation)
When Lx is smaller than 0, that is, when there is no overlap between the deposit reject unit casing 40 on the upstream side of the conveyance and the protrusion tip locus 101, the deposit reject unit casing 40 is placed on the deposit reject unit casing 40 as shown on the left side of FIG. If there is a remaining jammed banknote 100x, it cannot be scraped out by the protrusion 50 and remains as it is.

  When Ly is smaller than 0, that is, when there is no overlap between the extension line 102 at the right end on the downstream side of the conveyance guide 90 and the protrusion tip locus 101, the jammed banknote 100z remaining below the protrusion belt 26 is Since it is pushed by the protrusion 50 and only moved to the right as shown in the right side of FIG. 7C, it cannot be scraped out by the protrusion 50, and therefore remains on the transport guide 90 as it is.

  Therefore, by setting Lx to 0 or more, even the jammed banknote 100x remaining on the deposit reject unit housing 40 can be surely scraped off to the lower side of the deposit reject unit housing 40. Then, by setting Ly to 0 or more, the jammed banknote 100y remaining on the transport guide 90 shown on the right side of the figure can be scraped out by the protrusion 50, and can be transported to the pool section 21. Can be returned to Therefore, even if it is a jam banknote, it does not remain in the deposit rejection part 3.

(Effect of Example 2)
As described above, according to the banknote depositing / dispensing machine according to the second embodiment, a range in which the conveyance upstream side housing of the deposit rejection unit and the protrusion tip locus overlap is provided, and the conveyance downstream end extension line and the protrusion tip of the conveyance guide are provided. Since the range in which the trajectory overlaps is provided, it is possible to reliably prevent jammed banknotes from remaining in the deposit reject part.
