[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a coin change machine used when coins are paid out in coins.
[0002]
[Prior art]
  2. Description of the Related Art Conventionally, a coin change machine used when paying out change with coins is known. This coin changer sends out coins of multiple denominations thrown into the input hopper toward the coin passage, sorts the coins by denomination by a plurality of sorting holes provided in the downstream position, and stores them after sorting It is made to store every denomination in the department. A plurality of sorting holes corresponding to the diameters of coins of each denomination are provided, and the sorting holes are arranged in series in ascending order. The coins fed to the position of the sorting hole fall downward through the corresponding sorting hole and are stored in a storage hopper provided for each denomination. A predetermined amount of coins stored in the storage hopper is paid out for each denomination in response to a change request.
[0003]
  Since the second passage is laid out so as to extend in a direction orthogonal to the first passage, the storage hopper can be positioned in a space surrounded by the first passage and the second passage, There is an advantage that it contributes to the downsizing of the coin change machine as compared with the case where the first and second passages are connected in a straight line.
[0004]
[Problems to be solved by the invention]
  By the way, in the conventional coin change machine as described above, in order to sequentially stack the coins dropped from the sorting holes, a plurality of stacked hoppers extending in the vertical direction are provided in the storage portion for each denomination. Is common. When such a stacked hopper is used, the coins that have fallen from the sorting hole have their front or back surfaces landed, so the coins that have subsequently dropped sequentially land on the front and back surfaces, and are naturally stacked.
[0005]
  However, when such a vertically long stacked hopper is used, the coin change machine becomes long and bulky, resulting in an inconvenience of inhibiting compactness. In order to eliminate such inconvenience, it is conceivable that the stacked hopper is placed horizontally and the coins that have fallen to the upstream end of the stacked hopper are sequentially conveyed toward the downstream side in a standing state and stacked. There is a new problem that the structure for carrying in a standing state becomes complicated and difficult to realize.
[0006]
  The present invention has been made to solve the above-described problems, and it is possible to stack and store selected coins in a standing state while having a simple structure, thereby reducing the size. It aims at providing the coin change machine which can plan easily.
[0007]
[Means for Solving the Problems]
  The invention according to claim 1 sequentially draws out coins from an insertion hopper into which coins of a plurality of denominations are inserted, sorts the coins for each denomination, stores each selected coin for each denomination, and responds to a request. A coin change machine configured to pay out coins for each denomination required, a sorting means for sorting out coins discharged from the input hopper, and a coin sorted by the sorting means for each denomination. The storage means is arranged in parallel for each denomination, and the groove width dimension is slightly wider than the diameter of the coin.Inclined forward toward the coin transport directionA plurality of coin storage grooves,eachA conveyor belt extending in the longitudinal direction disposed at the groove bottom of the coin storage groove, and a payout means for changing the posture so that coins are discharged from the downstream end of the coin storage groove in an operating state while coins are stacked in a non-operating state And a coin change machine. It is a feature.
[0008]
  According to this invention, the coins sorted by the sorting means are introduced into the coin storage groove of the storage means, and conveyed toward the downstream side by the circulation of the conveyor belt provided at the groove bottom. Then, by setting the payout means to the non-operating state, the first coin is converted into a posture that can be stacked when it reaches the payout means, so that the next coin is the first coin that has become ready for stacking. By being guided so as to ride on the surface and stacked vertically, this stacking operation is sequentially repeated with subsequent coins, whereby the coins are stacked approximately vertically in the coin storage groove.
[0009]
  When paying out coins stored vertically in the coin storage groove, the posture of the payout means is changed to a passable posture. By doing so, the coins are paid out to the outside through the payout means that can pass through.
[0010]
  In this way, coins can be stacked vertically by setting the dispensing means provided at the downstream end of the coin storage groove in a stackable posture, so there is no need to place the coin storage groove vertically, By doing so, the vertical length of the coin change machine can be lowered, which contributes to the downsizing of the coin change machine.
[0011]
  According to a second aspect of the present invention, in the first aspect of the present invention, the conveyor belt is disposed on one side of the groove bottom of the coin storage groove.
[0012]
  According to this invention, the coin is advanced at the groove bottom of the coin storage groove by driving the conveyor belt provided on one side thereof, but at this time, the edge of the coin on the belt side advances. Since the opposite edge is in contact with the groove bottom, a rotational force is applied to the coin, and the coin advances while rotating. Therefore, since the coins whose peripheral portions are in contact with each other in the front and rear are in a state of competing with each other, they are always transported smoothly without causing a problem of clogging the passage.
[0013]
  The invention according to claim 3 is the invention according to claim 1 or 2, wherein the payout means includes a payout belt whose lower end faces the groove bottom of the coin storage groove in a state where the transport surface is inclined upward. And a payout control member having a stopper that is separated from and contacting the conveying surface of the payout belt.
[0014]
  According to this invention, the first coin conveyed toward the downstream side in the coin storage groove by the circulation of the conveyance belt is dispensed in a state where the stopper of the dispensing control member is in contact with the surface of the circulating dispensing belt. After being pulled up by being guided by the belt, it stops against the stopper and is prevented from further movement. Accordingly, the coin that has been continuously conveyed is in a state in which the leading edge thereof rides on the surface of the first coin, and a forward force is applied by the circulation of the conveyor belt. It is laminated almost upwards. By repeating such an operation on the subsequent coins with respect to the subsequent coins, the coins conveyed in the coin storage groove are sequentially stacked.
[0015]
  Next, when paying out the coins once stored in the coin storage groove in a stacked state, the stopper of the payout control member is separated from the surface of the payout belt. By doing so, since the movement of the coins by the stopper is released, the coins are transported by the circulation of the payout belt and discharged out of the system.
[0016]
  In this way, by providing a payout control member having a stopper in the vicinity of the payout belt, the coin can be removed by simply performing the separation / contact operation of the stopper with respect to the payout belt with both the transport belt and the payout belt being driven at all times. It becomes possible to control the storing operation and the dispensing operation of the stored coins, and the control structure for storing and dispensing the coins becomes simple.

The second conveyor belt 46 can circulate between the first to fourth pulleys 46a to 46d by the driving rotation of the third shaft 46g.
[0058]
  The second conveyor belt 46 is wound around the first to fourth pulleys 46a to 46d, so that the second conveyor belt 46 follows the shape on the second coin passage 42 as shown in FIG. The gap dimension between the lower surface of the forward belt and the upper surface of the bottom plate 41a is set slightly smaller than the thickness dimension of the coin C. Accordingly, the coin C on the second coin passage 42 pressed by the elastic deformation of the second transport belt 46 is caused by the second transport belt 46 circulating so that the forward belt goes downstream of the second coin passage 42. Then, it moves forward while sliding on the second coin passage 42 by the frictional force with the second conveyor belt 46.
[0059]
  By the way, in the present embodiment, the fourth pulley 46d is rotatably supported around a fourth shaft 46h (FIG. 9) that is obliquely lowered from a top plate at an appropriate position directly above the second pulley 46b. 11A and 11B are views showing the installation state of the fourth pulley 46d, where FIG. 11A is a perspective view and FIG. 11B is a cross-sectional view. As shown in FIG. 11, the fourth pulley 46 d has an inverted truncated cone shape as a whole, and the thickness dimension d is set to be larger than the diameter D of the second conveying belt 46. The upper part of the fourth shaft 46h is inclined outward (to the right of (b) in FIG. 11) at the bending position of the second conveyor belt 46. Accordingly, as shown in FIG. 11 (A), the second conveyor belt 46 is in contact with the inclined surface of the fourth pulley 46d, and the lower surface thereof is a coin as shown in FIG. It comes into contact with the surface of C.
[0060]
  According to the configuration of the fourth pulley 46d, the annular inclined surface of the fourth pulley 46d abuts on the second conveyor belt 46, thereby ensuring the support state of the second conveyor belt 46 by the fourth pulley 46d. Thus, the coin C can come into contact with the second transport belt 46.
[0061]
  And in this embodiment, the conveyance speed of the coin C conveyed by the circumference | surroundings of the 2nd conveyance belt 46 is a little faster than the circumferential speed of the said deceleration roller 45, and the coin C which moves the said 1st coin channel | path 31 is used. The speed is set so as to be slower than the transport speed. Therefore, a slight gap is formed between the coin C that has passed through the speed reduction roller 45 and the preceding and following coins C.
[0062]
  As shown in FIG. 10, the money sorting unit 50 is a position corresponding to the downstream end of the upstream straight passage 42 a of the bottom plate 41 a, and the right position of the second straight portion 43 c of the first positioning protrusion 43. The first sorting hole 51 drilled in the bottom plate and the sorting long hole 52 drilled at a position corresponding to the coin sorting passage 42c of the bottom plate 41a are provided.
[0063]
  In the present embodiment, the first sorting hole 51 is for sorting 1-yen coins, and the hole width dimension is slightly larger than the diameter of 1-yen coin and smaller than the diameter of 50-yen coin. In addition, the length dimension is set longer than the diameter of the 1-yen coin. Between the second straight part 43c of the first positioning protrusion 43 and the left end of the first sorting hole 51, an edge part of a coin C other than a one-yen coin is caught. A scratch edge 51a is formed.
[0064]
  Therefore, the coin C other than the one-yen coin passing through the upstream straight passage 42a has the left edge on the first scratch edge 51a and the right edge is the right edge of the first sorting hole 51. Therefore, when the 1-yen coin passes through the upstream linear passage 42a, the left edge of the one-yen coin passes through the first scratching passage 42a without being fitted into the first sorting hole 51. Since the right end edge does not hang on the right edge of the first scratch edge 51a in a state of being hooked on the edge 51a, the right edge is fitted in the first sorting hole 51. In this way, the coins C can be sorted into 1-yen coins and other coins by passing them through the upstream straight passage 42a.
[0065]
  In the present embodiment, the sorting long hole 52 is for sorting coins C other than 1-yen coins, and has a hole width dimension larger than the diameter of 50-yen coins and from the diameter of 5-yen coins. The second sorting hole 53 having a small dimension, the third sorting hole 54 having a hole width dimension larger than the diameter of the 5-yen coin and smaller than the diameter of the 100-yen coin, and a hole width dimension of 100 yen The fourth sorting hole 55 that is larger than the diameter of the coin and smaller than the diameter of the 10-yen coin, and the hole width is larger than the diameter of the 10-yen coin and smaller than the diameter of the 500-yen coin. The fifth sorting hole 56 and the sixth sorting hole 57 whose hole width dimension is set larger than the diameter of the 500-yen coin. The second to sixth sorting holes 53 to 57 communicate with each other in the width direction to form a sorting long hole 52.
[0066]
  The edge of the coin C is slightly caught between the rear edge (upward in the drawing of FIG. 10) of the sorting slot 52 and the protrusion main body 44a of the second positioning protrusion 44.WidthA second scratch edge 52a having a dimension of 0.5 mm or less is provided.
[0067]
  According to the money sorting unit 50 configured as described above, the coin C sent out from the first coin passage 31 is decelerated to a predetermined speed by the speed reduction roller 45, and then the left edge portion is set by the first positioning protrusion 43. In a state of being positioned along the first positioning protrusion 43, it is transferred to the second conveyor belt 46 at a substantially intermediate position of the upstream straight path 42a.
[0068]
  The coin C delivered to the second conveyor belt 46 advances while sliding on the second coin path 42 by its circulation while being pressed by the second conveyor belt 46, and first reaches the first sorting hole 51. When the coin C reaches the first sorting hole 51, the left edge portion is in contact with the second straight portion 43c, so that the coin C is put on the first scratching edge portion 51a. In this state, when the coin C is a one-yen coin, the right edge of the coin C does not hang on the right edge of the first sorting hole 51, so the coin C falls downward through the first sorting hole 51. On the other hand, in the case of the coin C other than the one-yen coin, the right edge portion is in a state of being hooked on the right edge portion of the first sorting hole 51, and therefore, the coin C moves forward through the first sorting hole 51. Become.
[0069]
  Next, the coin C other than the one-yen coin that has passed through the first sorting hole 51 enters the curved path 42 b by the circulation of the second conveyance belt 46. Here, although the second conveyor belt 46 is bent leftward, the coin C advances straight due to inertial force and collides with the arc edge surface 44c of the arc protrusion 44b, and then the arc edge surface 44c. And turn counterclockwise. Therefore, after that, the coin C is in a positioning state in which the right edge (the rear edge on the basis of the (−Y) − (+ Y) direction) of the coin C is engaged with the second scratch edge 52a. 42c will be advanced.
[0070]
  When the coin C is a 50-yen coin, it falls from the second sorting hole 53. When the coin C is a 5-yen coin, it falls from the third sorting hole 54. When the coin C is a 100-yen coin, When the coin C is a 10-yen coin, it falls from the fifth sorting hole 56, and when the coin C is a 500-yen coin, it falls from the sixth sorting hole 57.
[0071]
  Next, the coin storage unit 60 will be described with reference to FIG. 12 and the previous FIG. 5 and FIG. 12 is a cross-sectional view of the coin storage unit 60 shown in FIG. 6 in a side view, and FIG. 13 is a partially enlarged view of FIG.

[0072]
  The sliding plate 61 is shown in FIG.6 and 13As shown in FIG. 5, the coin C that has fallen through the respective sorting holes 51, 53 to 57 is received and guided to the coin storage plate 62, and has a convex arc shape in a side view, Edge weirs 61 a slightly higher than the thickness dimension of the coin C are provided on both sides in the width direction of the sliding plate 61 so that the received coin C can be smoothly guided toward the coin storage plate 62.
[0073]
  The coin storage plate 62 isAs shown in FIG. 12 and FIG.In the base frame 11a, it is provided so as to be inclined from the rear to the front. The coin storage plate 62 has a corrugated shape in which a portion corresponding to each of the sliding plates 61 extends in the front-rear direction, a coin storage groove 63 is formed in the recessed portion, and a coin storage is performed. Partition ridges 64 extending in the front-rear direction are formed between the grooves 63.
[0074]
  The coin storage groove 63 isAs shown in FIG. 5, FIG. 12, and FIG.Corresponding to the first to sixth sorting holes 51 and 53 to 57 of the money sorting unit 50, the first storage groove 63a, the second storage groove 63b, the third storage groove 63c, the fourth storage groove 63d, and the fifth from the right. There are six rows of storage grooves 63e and sixth storage grooves 63f. A storage hopper according to the present invention is formed by the six coin storage grooves 63. Therefore, the 1-yen coin is in the first storage groove 63a, the 50-yen coin is in the second storage groove 63b, the 5-yen coin is in the third storage groove 63c, the 100-yen coin is in the fourth storage groove 63d, The 500 yen coin is stored in the sixth storage groove 63f in the fifth storage groove 63e.
[0075]
  The accumulation belt 65 has a belt width dimension set narrower than the radius of the smallest coin C and is provided so as to be in sliding contact with the right side portion of the groove bottom of the coin storage groove 63 as shown in FIG. It has been. As shown in FIG. 12, the integrated belt 65 is stretched between the front pulley 65a and the rear pulley 65b. In the rear pulley 65b, the driving force of the second motor 34 is supported so that the second reduction gear group 35 (FIGS. 3 and 10), the third reduction gear group 47 (FIG. 10), and the rear pulley 65b can rotate integrally. It is transmitted via the rear drive shaft 65c. The front pulley 65a rotates integrally around the front driven shaft 65d.
[0076]
  Therefore, the coin C introduced into the coin storage groove 63 in a state in which the accumulation belt 65 circulates between the front pulley 65a and the rear pulley 65b by the driving of the second motor 34 has the left edge portion of the groove of the coin storage groove 63. By abutting against the bottom, the coin storage groove 63 moves forward while rotating clockwise.
[0077]
  As shown in FIG. 6, the coin dispensing unit 70 includes a dispensing belt 71 that is diagonally opposed to the downstream end thereof corresponding to the coin storage plate 62, and a diagonally opposite to the dispensing belt 71 on the front lower surface of the opening / closing frame 11 b. , A coin presser member 72 disposed so as to face each other, a stop member (payout control member) 73 for stopping the carry-out of the coin C, and a solenoid member 74 for operating the stop member 73. . The coin C paid out by driving the payout belt 71 is discharged toward a coin tray 14 provided on the front end wall of the basic frame 11a.
[0078]
  FIG. 14 is an explanatory view in a side view for explaining the coin dispensing unit 70, (a) is a state where the stop member 73 is set at the stop position, and (b) is a stop release of the stop member 73. Each of the states set to the position is shown. As shown in this figure, the payout belt 71 is a lower payout pulley 71a attached to the front driven shaft 65d so as to be integrally rotatable, and an upper front portion of the lower payout pulley 71a, facing the rear part of the coin tray 14. It is stretched between the upper payout pulley 71b provided at the vertical position, and is thus inclined forward and forward. In this embodiment, this inclination angle is set to approximately 40 ° with respect to the bottom plate of the basic frame 11a.
[0079]
  Further, the bottom plate 63g of the coin storage groove 63 is opposed to the surface of the payout belt 71 at a position where its front end is wound around the lower payout pulley 71a via a slight gap.
[0080]
  The coin holding member 72 is used to stabilize the carry-out state by pressing the coin C carried out from the coin storage groove 63 around the payout belt 71, and is formed by a rectangular parallelepiped box. The coin presser member 72 is positioned so as to face the payout belt 71 with a predetermined gap (a gap slightly larger than the thickness dimension of the thickest coin C) slightly above the intermediate position of the forward belt of the payout belt 71. While being set, a through hole 72b is formed in the bottom plate 72a, and a steel ball 72c is internally provided so that the peripheral surface protrudes from the through hole 72b.
[0081]
  In the state where the coin C is being carried out by the payout belt 71, the steel ball 72 c presses the surface of the coin C between the back surface of the coin C and the surface of the payout belt 71 as shown in FIG. It plays the role of a weight that applies frictional force between them to prevent slipping between the two, whereby the carry-out state of the coin C is stabilized.
[0082]
  The stop member 73 has an L-shaped operation rod 73a composed of a first operation piece 73b and a second operation piece 73c, and a front end of the second operation piece 73c so as to face the first operation piece 73b. The stopper pin 73d is attached.
[0083]
  In the stop member 73, the joint point between the first operation piece 73b and the second operation piece 73c rotates around the support shaft 73e in a state where the coin pressing member 72 is sandwiched between the first operation piece 73b and the stopper pin 73d. A stop posture that is supported freely and has a stopper pin 73d that stops at the front edge of the coin C on the payout belt 71 to prevent the payout of the coin C, as shown in FIG. As shown in (b) of FIG. 14, the posture can be changed between the stop release posture in which the stop is released.
[0084]
  Further, the weight of the stopper pin 73d is set such that the weight of the stopper pin 73d can cause a moment in the clockwise direction around the support shaft 73e with respect to the stop member 73, whereby the stop member 73 is normally set in the stop posture. It is like that.
[0085]
  The solenoid member 74 includes a solenoid main body 74a in which magnetic force generation is turned on / off by an on / off operation of current supply, and a rod-shaped iron core 74b that is housed in the solenoid main body 74a so as to be able to appear and retract. The solenoid body 74a is in a state where the iron core 74b is set at the retracted position, and the tip of the solenoid main body 74a contacts the lower end portion of the first operation piece 73b set in the stop position, and the tip of the iron core 74b is protruded. However, the installation position is set so that the first operation piece 73b can be pressed to change the position of the stop member 73 to the stop release position.
[0086]
  According to the coin dispensing unit 70 configured in this manner, the coin C that has moved while rolling on the bottom plate 63g of the coin storage groove 63 around the accumulation belt 65 reaches the dispensing belt 71. The tip of the payout belt 71 is lifted upward by the circulation of the payout belt 71 and is brought into close contact with the surface of the payout belt 71. In this state, the front end is brought into contact with the stopper pin 73 d of the stop member 73, so that the coin C is maintained in its current position while sliding relative to the surface of the payout belt 71.
[0087]
  Then, after the first coin C stops on the payout belt 71, the coins C that follow this stop.(Later coin C)The tip part is in contact with the surface of the previous coin CIn this state, the edge is rotated by the circulation of the accumulation belt 65, so thatIn order to be auctioned sequentially,Eventually, the later coins C ran over the previous coins C,In the coin storage groove 63, a plurality of coins C are stored in an obliquely stacked state as shown in FIG.
[0088]
  Next, when the solenoid main body 74a is turned on, the first operating piece 73b is pressed by the protrusion of the iron core 74b from the solenoid main body 74a, and the stop member 73 rotates counterclockwise around the support shaft 73e. The tip of the stopper pin 73d is separated from the surface of the payout belt 71 by the rotation.
[0089]
  Then, as shown in FIG. 14B, the coin C positioned at the forefront in the coin storage groove 63 moves obliquely upward toward the front along the circumference of the payout belt 71, and the payout belt 71 and the coin presser member. It will be paid out toward the coin tray 14 through the gap with 72.
[0090]
  Since the time for the iron core 74b to appear and disappear from the solenoid main body 74a is set to be very short, the stop member 73 is returned to the original stop posture immediately after the coin C dives under the tip of the stopper pin 73d. Accordingly, since the coin C is carried out by the payout belt 71 with the tip of the stopper pin 73d in contact with the surface thereof, the stopper pin 73d returns to its original position immediately after the coin C is removed from the tip. The next coin C is prevented from being carried out by the stopper pin 73d until the iron core 74b appears and disappears again.
[0091]
  FIG. 15 is a block diagram for explaining the control of the coin change machine 10 by the control unit 80. As shown in this figure, the control unit 80 is for comprehensively controlling various operations of the coin change machine 10 and employs a so-called microcomputer. The control unit 80 includes a CPU 81 that is a central processing unit, a ROM 82 that is a read-only external storage device in which a control program and the like are stored, and a readable / writable external storage device that temporarily stores various data. And a RAM 83. An input device 84 and an output device 85 are connected to the control unit 80.
[0092]
  As the input device 84, in addition to the operation button 12 d and the numeric keypad 12 f, for example, a repeater 841 that relays a signal from, for example, a cash register as a parent machine of the coin change machine 10 is employed. As the output device 85, various display lamps 851 are employed in addition to the 7-segment LED 12e.
[0093]
  Further, a plurality of coin sensors that detect the coin C and input the detection result to the control unit 80 are provided at various locations in the coin change machine 10. As shown in FIG. 7, the coin sensor includes a hopper sensor 861 that detects the presence or absence of the coin C in the insertion hopper 21, a clogging sensor 862 that detects clogging of the coin C in the first coin path 31, and first to sixth. A first sorting sensor 863, a second sorting sensor 864, a third sorting sensor 865, a fourth sorting sensor 866, and a fifth sorting sensor that detect coins C sorted by the sorting holes 51, 53, 54, 55, 56, and 57. 867, the sixth selection sensor 868, the first storage sensor 869, the second storage sensor 870, and the third storage sensor 871 for detecting the storage status of the coin storage groove 63 corresponding to the first to sixth selection holes 51, 53-57. , A fourth storage sensor 872, a fifth storage sensor 873, a sixth storage sensor 874, and first to sixth provided in the vicinity of each payout belt 71 of the coin payout portion 70. The first dispensing sensor 875 corresponding to the cut sensor 869 to 874, the second dispensing sensor 876, a third dispensing sensor 877, fourth dispensing sensor 878, fifth dispensing sensor 879 and the sixth payout sensor 880 or the like is employed.
[0094]
  Further, a safety sensor 881 for detecting that a hand has been inserted is provided at an appropriate position in the back of the coin tray 14. This safety sensor 881 is for ensuring safety so that the hand is not touching the circulating dispensing belt 71.
[0095]
  In this embodiment, an appropriate control signal is sent from the CPU 81 to the first motor 23, the second motor 34 or the solenoid body 74a based on the input signal from the input device 84 and the detection signals from various sensors. The coin change machine 10 is appropriately operated by driving the first motor 23, the second motor 34, and the solenoid body 74a.
[0096]
  Then, the coin change machine 10 inputs a large number of coins C mixed with each denomination into the input hopper 21, and inputs the coins operated to store these coins C in the coin storage unit 60 for each denomination. The operation and the change dispensing operation for dispensing the coin C once stored in the coin storage unit 60 as change are controlled by the control unit 80 and operated.
[0097]
  When operating in a mode in which a coin insertion operation is performed, first, the power switch 12g is turned on, then a predetermined operation button 12d indicating the coin insertion mode is pressed, and a plurality of coins C are subsequently inserted into the insertion hopper 21. Then, the hopper sensor 861 detects the presence of the coin C in the insertion hopper 21, and this detection signal is input to the control unit 80, so that the control unit 80 directs the first motor 23 and the second motor 34. The drive signal is output, and the first motor 23 and the second motor 34 thereby drive the rotating tray 22 around the central axis 22a, and the first conveyor belt 32, the second conveyor belt 46, and the integrated belt 65 Go around.
[0098]
  Then, the coin C fed to the first coin passage 31 from the feeding hole 21 a of the charging hopper 21 by the rotation of the rotating tray 22 is conveyed toward the second conveying unit 40 while being guided by the circulation of the first conveying belt 32. The At this time, if a clogging detection signal is output from the clogging sensor 862, a stop signal is output from the control unit 80 to the first motor 23 and the second motor 34, and the operation is temporarily suspended due to the stoppage of the device. The When such an interruption occurs, the passage cover 36 is opened, the first coin passage 31 is inspected, and the operation is resumed in a state where the clogging is eliminated.
[0099]
  Next, the coin C that has reached the second coin path 42 falls from any of the sorting holes 51 and 53 to 57 while being transported through the second coin path 42 by driving the second transport belt 46. Which of the sorting holes 51 and 53 to 57 is dropped is detected by any of the first to sixth sorting sensors 863 to 868, and the CPU 81 counts the number of coins of each denomination one by one based on this detection signal. . When selection of all coins C in the insertion hopper 21 is completed, the number of coins C for each denomination is stored in the RAM 83.
[0100]
  Then, the coins C that have fallen from any of the sorting holes 51 and 53 to 57 and supplied to the coin storage unit 60 are guided by the circulation of the accumulation belt 65 toward the coin dispensing unit 70 in the coin storage groove 63. It is transported and sequentially stacked obliquely. When a predetermined storage allowable amount is exceeded in any of the coin storage grooves 63 during the conveyance, this is detected by one of the first to sixth storage sensors 869 to 874, and a stop signal from the CPU 81 is thereby detected. The first motor 23 and the second motor 34 are stopped. Since this is output to the output device 85, a predetermined treatment is performed based on this output.
[0101]
  When the input amount of coins C does not exceed the storage allowable amount of the coin storage groove 63, the operation is continued until the hopper sensor 861 detects that the input hopper 21 is empty. When it is detected by the hopper sensor 861 that the charging hopper 21 has become empty, a timer (not shown) is activated, and the first motor 23 and the second motor 34 are set after a time set in advance in the timer. Is stopped and the operation in the coin insertion mode is ended.
[0102]
  Next, in the change dispensing mode, a signal indicating that is input from the input device 84. If it does so, the coin change machine 10 will be set to the position which can receive the signal from the cash register machine of illustration not shown via the repeater 841. Then, when a signal for paying out a predetermined change is input from the cash register to the control unit 80, the CPU 81 calculates the number of coins C of coins for each denomination so as to correspond to the amount of money, A signal corresponding to the number of sheets is output to the solenoid body 74a corresponding to the coin storage groove 63 storing these denominations.
[0103]
  Accordingly, upon receiving this signal, the solenoid member 74 holds the state in which the solenoid body 74a is excited and the tip of the stopper pin 73d is separated from the accumulation belt 71, and when a predetermined number of coins C are paid out, the solenoid body 74a The stopper pin 73d is returned to its original position by demagnetizing, and the coin C stored in the coin storage groove 63 is thereby paid out toward the coin tray 14 by the number set by the circulation of the payout belt 71. Become.
[0104]
  The number of payouts is detected one by one by the first to sixth payout sensors 875 to 880 and stored in the RAM 83. Therefore, it is possible to always confirm the receipt and payment of the coins C and the remaining amount of the coins C based on the storage result of the RAM 83 and the initial number of the coin storage units 60 counted during the coin insertion mode. This remaining amount value is displayed on the 7-segment LED 12e. Furthermore, a plurality of remaining amount display LEDs corresponding to each denomination may be provided, while each remaining amount may be displayed by turning on the LED.
[0105]
  As described in detail above, the present invention sequentially draws out coins C from the input hopper 21 into which coins C of a plurality of denominations are inserted, sorts the coins by denomination, and selects the selected coins C by denomination. The coin change machine 10 is configured so as to be stored in the storage unit 60 and to pay out coins C for each denomination required from the coin storage unit 60 upon request. A coin sorting unit 50 that sorts out the discharged coins C and a coin storage unit 60 that stores the coins C sorted by the coin sorting unit 50 for each denomination are provided. A plurality of coin storage grooves 63 that extend in a substantially horizontal direction and have a groove width dimension slightly wider than the diameter of the coin C, and a longitudinal direction that is disposed at the bottom of the coin storage groove 63. An accumulation belt 65 extending to the bottom of the coin storage groove 63 And the operating state capable of passing the coin C which is provided at an end
The coin C sorted by the money sorting unit 50 is a coin because it is configured to include the stop member 73 that changes its posture between the non-operating state that prevents the coin C from being dispensed so that the subsequent coin C can be stacked. It is introduced into the coin storage groove 63 of the storage unit 60 and conveyed toward the downstream side by the circumference of the accumulation belt 65 provided at the bottom of the groove. Then, the first coin C reaches the stop member 73 that is provided at the downstream end of the coin storage groove 63 and is set in a stackable posture. In order to be converted into a posture to obtain, the next coin C is guided to ride on the surface of the first coin C that can be stacked, and is stacked in a so-called piled state inclined forward so that the upper end leans, By sequentially repeating this stacking operation with the subsequent coins C, the coins C are sequentially stacked in a substantially vertical position in the coin storage groove 63.
[0106]
  When paying out the coin C stored vertically in the coin storage groove 63, the posture of the stop member 73 is changed to a passable posture. By doing so, the coin C is paid out to the outside through the stop member 73 that can pass through.
[0107]
  Thus, since the coin C can be stacked vertically by setting the stop member 73 provided at the downstream end of the coin storage groove 63 in a stackable posture, the coin storage hopper is placed vertically. Thus, the conventional inconvenience can be solved and the coin change machine 10 can be made compact.
[0108]
  Then, by disposing the accumulation belt 65 on one side of the groove bottom of the coin storage groove 63, the coin C is the accumulation belt 65 provided on one side of the groove bottom of the coin storage groove 63. At this time, the belt-side edge of the coin C moves forward, while the opposite edge is in contact with the groove bottom, so that a rotational force is applied to the coin C. Therefore, the coin C moves forward while rotating. Accordingly, the coins C whose peripheral portions are in contact with each other in the front and rear are in a state of competing with each other, so that the coins C can be transported smoothly and smoothly without causing a problem of clogging the passage.
[0109]
  Further, the coin payout portion 70 is provided with a payout belt 71 whose lower end faces the groove bottom of the coin storage groove 63 in a state where the transfer surface is inclined upward, and a stopper that is separated from and in contact with the transfer surface of the payout belt 71. Since the stop member 73 having the pin 73d is provided, the stopper pin 73d of the stop member 73 is rotated around the first coin C conveyed toward the downstream side in the coin storage groove 63 by the circulation of the accumulation belt 65. After being pulled up by the payout belt 71 while being in contact with the surface of the payout belt 71, the belt is stopped against the stopper pin 73d to prevent further movement. Therefore, the coin C that has been continuously conveyed is in a state in which the leading edge thereof rides on the surface of the first coin C, and forward force is applied by the circulation of the accumulation belt 65, and the subsequent coin C is In order to move forward while rotating, the front edge of the subsequent coin C abuts on the convex portion on the surface of the first coin C and moves forward so as to ride on the convex portion, and is stacked on the first coin C. By repeating such an operation for the subsequent coins C with respect to the subsequent coins C, the coins C transported in the coin storage grooves 63 can be sequentially stacked.
[0110]
  Next, when paying out the coins C stored in the coin storage groove 63 once in a stacked state, the stopper pin 73 d of the stop member 73 is separated from the surface of the payout belt 71. By doing so, since the movement prevention of the coin C by the stopper pin 73d is released, the coin C can be conveyed by the circulation of the payout belt 71 and discharged out of the system.
[0111]
  In this manner, by providing the stop member 73 having the stopper pin 73d in the vicinity of the payout belt 71, the stopper pin 73d is separated from the payout belt 71 in a state where both the accumulation belt 65 and the payout belt 71 are always driven. It is possible to control the storing operation of the coins C and the paying-out operation of the stored coins C only by performing the contact operation, and the control structure for storing and discharging the coins C can be simplified.
[0112]
  The present invention is not limited to the above embodiment, and includes the following contents.
[0113]
  (1) In the above-described embodiment, the payout belt 71 and the collecting belt 65 are connected to each other so as to simultaneously circulate via the front pulley 65a. Instead, the two are connected to each other from separate drive sources. You may make it drive in the state which acquired drive force and was mutually independent of the other party. In this way, when the coins C are stacked in the coin storage groove 63, the payout belt 71 is stopped, while when the coins C are paid out, the payout belt 71 can be driven to cope with the stop. Installation of the member 73 and the solenoid member 74 can be omitted. In addition, by doing so, it becomes possible to make a simple coin dispensing position of the coin change machine 10 into a simple structure, and maintenance becomes easy.
[0114]
  (2) In the above embodiment, the coin tray 14 is fixed at the lower position on the front surface of the basic frame 11a. Instead of this, the coin tray 14 is detachably mounted on the lower front surface of the basic frame 11a. May be. About the attachment or detachment structure with respect to the basic frame 11a of the coin receiving tray 14, while providing a magnet in the back surface of the coin receiving tray 14, or providing a locking protrusion on the opposing surface of the basic frame 11a, this locking protrusion on the back surface of the coin receiving tray 14 is provided. The structure etc. which provide the locking hole corresponding to can be mentioned. By configuring the coin tray 14 so as to be detachable with respect to the base frame 11a, when the coin tray 14 is paid out, the coin tray 14 is detached from the base frame 11a and is directly used by the customer. It can be conveniently used as a corresponding tray.
[0115]
  (3) In the above embodiment, the first coin belt 31 is provided with the first conveyor belt 32 over the entire length in the conveying direction on one side thereof. The conveying belt 32 is not limited to being provided only on one side of the first coin passage 31, and the first conveying belt 32 may be provided on both sides of the first coin passage 31, A wide belt that covers the entire surface of the coin passage 31 may be adopted..

[The invention's effect】
  According to the invention described in claim 1, since the coins can be stacked vertically by setting the payout means provided at the downstream end of the coin storage groove in a non-operating state, the coin storage groove is placed vertically. This eliminates the need to do this, so that the vertical length of the coin change machine can be lowered by placing it sideways, which can contribute to making the coin change machine more compact.
[0117]
  According to the second aspect of the present invention, since the conveyor belt is disposed on one side of the groove bottom of the coin storage groove, the coin is rotated while being advanced around the conveyor belt, and the peripheral edges abut against each other in the front and rear. The coins that are competed with each other are in a state of competing with each other, so that no troubles such as clogging of the passage occur, and the coins can always be conveyed smoothly.
[0118]
  According to the third aspect of the present invention, the payout means is separated from the payout belt with the lower end facing the groove bottom of the coin storage groove in a state in which the transfer surface is inclined upwards, and the transfer surface of the payout belt. Since the payout control member having the stopper in contact is provided, the coin storage operation and the stored coins can be stored only by performing the contact / separation operation of the stopper with respect to the payout belt in a state where both the conveying belt and the payout belt are always driven. The payout operation can be controlled, and the coin storage and payout control structure can be simplified.
