  In Patent Document 1, although a storage unit and a payout unit connected to the storage unit corresponding to each denomination of coins are configured, a plurality of storage units are formed as an integrated product, and the payout of each payout unit The pulley on which the belt is stretched is directly connected to each other by a common drive shaft so that the payout portion and the storage portion are integrated. For this reason, some storage units or payout units, for example, 100 yen coin storage units or payout units need to be repaired or parts need to be replaced, or some storage units or payout units are clogged. When it is necessary to remove the coins, foreign matters, etc., first, the connection of the payout part by the drive shaft is released, that is, the payout part, the storage part and their peripheral parts are disassembled, and then the storage part to be maintained Or it is necessary to remove a payout part from the base frame which accommodates them. At this time, not only the storage unit or payout unit to be maintained, but also the storage unit or payout unit that does not require maintenance is removed from the base frame. As described above, the coin change machine disclosed in Patent Document 1 requires time and labor for maintenance work.

  Furthermore, for multiple types of coin changers with different types of coins to be handled, for example, a coin changer that handles coins of all denominations, and a coin changer that handles only 10 yen coins, 100 yen coins, and 500 yen coins. For a machine, since it is necessary to design and manufacture an integrated product of a storage part and a payout part for each model, versatility is low.

  In view of the above problems, an object of the present invention is to provide a coin change machine with improved maintainability and high versatility.

In order to achieve the above object, a coin change machine according to the present invention includes a basic frame, a loading hopper into which coins are thrown, a sorting unit that sorts coins thrown into the loading hopper for each denomination, A sorting unit is provided for each denomination of coins that can be sorted, and each is a denomination unit that can be attached to and detached from the basic frame, and stores the coins sorted by the sorting unit, and the storage The denomination unit having a payout unit for paying out coins stored in the unit, and positioning means capable of individually positioning each denomination unit with respect to the basic frame. The positioning means includes a notch formed in each denomination unit and an engaging member provided in the base frame and extending across the plurality of denomination units arranged. The engaging member is formed with a plurality of engaging groove portions that can engage the notch portions of each denomination unit. Each denomination unit has an internal dimension corresponding to the diameter of the denomination coin selected by the selection unit. Two notches are formed for each denomination unit in the width direction of the denomination unit. Each of the engagement groove portions includes two engagement grooves corresponding to the two notch portions, and the dimension between the engagement grooves corresponds to the inner dimension of the corresponding denomination unit.

  According to the coin change machine according to the present invention, the denomination unit constituted by each storage unit and the corresponding payout unit is set to be detachable from the base frame separately from each other. 100 yen coins when it is necessary to repair a corresponding denomination unit or replace parts of that denomination unit, or when it is necessary to remove a clogged coin, foreign object, etc. Only the money type unit can be removed from the base frame and repaired, parts can be replaced, etc. with other money type units attached to the base frame. As described above, the coin change machine of the present invention has a configuration in which it is not necessary to remove another denomination unit that does not require maintenance from the base frame in order to repair some denomination units or replace parts. Good maintainability.

  For example, a coin changer that handles all types of coins and a coin changer that handles only 10-yen coins, 100-yen coins, and 500-yen coins. The machine can be handled by simply selecting a denomination unit corresponding to the denomination to be selected and attaching it to the base frame. For this reason, it is also possible to make the basic frame common to a plurality of models. Thus, unlike the conventional coin change machine, the coin change machine of the present invention does not have to be designed and manufactured individually for all models of the storage part and the payout part. Is expensive.

Furthermore, the coin change machine has positioning means capable of individually positioning each denomination unit with respect to the basic frame. Thereby, a denomination unit can be individually positioned with respect to a basic frame.

Furthermore, the positioning means includes a notch formed in each denomination unit, and an engagement member that is provided in the base frame and has a shape that extends across a plurality of the denomination units arranged, The engaging member is formed with a plurality of engaging groove portions that can engage the notch portions of each denomination unit. Thus, for example, even when the denomination units are attached with a gap between them, or even when some denomination units are not attached, the direction extending over the plurality of denomination units by the engaging member, that is, the denomination It is possible to prevent the denomination unit from moving in the direction in which the units are arranged.

Furthermore, each denomination unit has an internal dimension corresponding to the diameter of the coin of the denomination selected by the selection unit, and the notch is provided for each denomination unit. Two engagement grooves are formed in the width direction, and each of the engagement groove portions includes two engagement grooves corresponding to the two notches, and the dimension between the engagement grooves corresponds to the corresponding money type. Corresponds to the internal dimensions of the unit. As described above, since the engagement groove portion having the dimension between the engagement grooves corresponding to the inner dimension of the denomination unit corresponding to the denomination to be selected is provided, the denomination unit other than the denomination to be selected is erroneously set. Thus, it is possible to prevent the fitting groove portion from being attached. Therefore, the denomination unit can be reliably arranged at a predetermined position.

In good preferable embodiment of the present invention, each gold type unit has a locking projection, said base frame, said locking projection has engageable locking hole, the locking The stop protrusions are formed at positions or shapes different from each other with respect to at least one denomination unit having a different width dimension.

The coin loading section 7 includes a loading hopper 27 into which a plurality of types of coins C are loaded, and a delivery belt 28 that is disposed below the loading hopper 27 and feeds the coins C to a coin transport section 9 described later. The charging hopper 27 has an upper opening 29 that opens on the upper surface of a main body cover (not shown), and a lower opening 30 that opens to the delivery belt 28 of the charging hopper 27. The delivery belt 28 is driven to rotate clockwise by a drive motor (not shown), and sends the coins C inserted into the insertion hopper 27 to the coin transport section 9 arranged behind the coin insertion section 7 (−X direction). .

  As shown in FIGS. 1 and 2, the coin transport section 9 and the coin sorting section 11 have a transport path 33 through which the coin C is transported. A transport path cover 32 that covers the transport path 33 is provided in the first base frame 3 so as to be rotatable around a support shaft (not shown). FIG. 2 shows a state in which the transport path cover 32 is opened. ing. The conveyance path 33 is substantially 90 ° in the width direction (from + Y direction to −Y direction) of the first basic frame 3 from the first straight portion 34 extending in the −X direction from the coin insertion section 7 and from the downstream end of the first straight portion 34. It is a substantially L-shaped passage composed of a curved curved portion 35 and a second straight portion 36 extending in the −Y direction from the downstream end of the curved portion 35. The downstream end of the first straight portion 34 and the second straight portion 36 belong to the coin sorting section 11 described later.

  The upstream end 34 a of the first straight portion 34 is close to the delivery belt 28 of the coin insertion section 7. An intake belt 23 stretched between a pulley 38 and a pulley 39 is provided on the upstream side of the first straight portion 34. Further, a transport belt 25 is provided on the downstream side of the take-in belt 23 in the first linear portion 34. The conveyor belt 25 is a belt that extends along the first linear portion 34, the curved portion 35, and the second linear portion 36, and is supported by the support shaft 40 that supports the pulley 39 of the take-in belt 23 and around the support shaft 40. It is stretched between an upstream pulley 41 that rotates integrally with the pulley 39, an intermediate pulley 42 disposed in the bending portion 35, and a downstream pulley 43 disposed at the downstream end of the second linear portion 36. . The downstream pulley 43 is supported by a drive shaft 44 connected to the transport motor 21, and is driven to rotate counterclockwise by the transport motor 21 via the drive shaft 44. Accordingly, the take-in belt 23 is also driven to rotate counterclockwise. The intake belt 23, the conveyance belt 25, the pulleys 38 and 39, the upstream pulley 41, the intermediate pulley 42, and the downstream pulley 43 are provided on the conveyance path cover 32.

  The conveyance belt 25 and the take-in belt 23 are positioned so that a gap through which the coin C can pass is formed between the double belt and the conveyance path 33, and the coin C is transferred to each double belt and the conveyance path. In a state of being sandwiched between the belt 33 and the take-up belt 23, the carrier belt 25 and the take-in belt 23 are moved in the counterclockwise direction toward the coin sorting section 11 described later. Specifically, the coin C delivered to the coin transport section 9 by the delivery belt 28 of the coin insertion section 7 is upstream of the first linear portion 34 of the transport path 33 by the take-in belt 23 that rotates counterclockwise. In FIG. 2, the belt is drawn into the gap between the double belt portion of the take-in belt 23 and the first straight portion 34 and is transferred to the coin transport section 9. The coin C delivered to the coin transport section 9 is guided to the bending portion 35 along the first guide piece 46 provided on the first straight portion 34 and the second guide piece 48 provided on the bending portion 35. Subsequently, the coin C is turned by about 90 ° in the −Y direction by the second guide piece 48 provided from the downstream end of the first straight portion 34 to the curved portion 35, and the second straight portion 36, that is, the coin sorting. Guided to section 11.

  On the right side of the first straight part 34, a coin identifying part 50 is provided for determining whether or not the coin C being conveyed is genuine. For example, the coin identification unit 50 is a 5-yen coin, a hole sensor 51 that detects a hole of a 50-yen coin, an outer diameter sensor 52 that measures the outer diameter of the coin C, and the coin C appropriately along the first guide piece 46. It consists of a plurality of sensors such as a reference sensor 53 for confirming whether or not it is being conveyed, a material of coins, and a magnetic sensor (not shown) for mainly identifying whether it is white or non-bronze. Arranged behind the coin identifying unit 50 is an irregular coin discharge unit 55 that discharges the coin C determined to be an irregular coin from the transport path 33 to a discharge path (not shown). The irregular coin discharge unit 55 includes, for example, a solenoid body 57 having an irregular coin passage sensor 56 that detects that an irregular coin has passed, and a discharge pin (not shown) that can be retracted. When the coin C, which is determined to be an irregular coin by the coin identification unit 50, is detected by the irregular coin passage sensor 56, the coin C moves to the approximate center of the first linear portion 34 by a discharge pin protruding from the solenoid body 57. Then, it falls into a discharge hole 58 formed in the first straight portion 34 and is guided to a coin discharge port 60 (FIG. 4) provided at the front end portion of the second basic frame 5 by a drive belt 132 (FIG. 3) described later. It is burned.

  The coin sorting section 11 is for sorting the types of coins C, and includes a first sorting hole (five-yen coin sorting unit) 61 drilled in the downstream end of the first straight portion 34 of the transport path 33, 2 and an elongated second sorting hole 63 extending in the width direction YY along the straight line portion 36. In the present embodiment, the first sorting hole 61 is a hole for sorting 5-yen coins. A 5-yen coin passage sensor 65 for confirming the passage of 5-yen coins is disposed on the upstream side of the first sorting hole 61 and on the right side of the first straight portion 34, and on the left side of the first sorting hole 61.

When the passage of the 5-yen coin is confirmed by the 5-yen coin passage sensor 65, the shutter 66 is driven to the open state by the 5-yen coin sorting solenoid 67, and the 5-yen coin falls into the first sorting hole 61.

  On the other hand, the second sorting hole 63 is a hole for sorting coins other than 5-yen coins, for example, 1-yen coins, 50-yen coins, 100-yen coins, 10-yen coins and 500-yen coins. 1-yen coin sorting unit 70, 50-yen coin sorting unit 71 sorting 50-yen coin, 100-yen coin sorting unit 72 sorting 100-yen coin, 10-yen coin sorting unit 73 sorting 500-yen coin and 500-yen coin Are arranged in parallel from the smallest diameter of the coin C to the largest. Each coin sorting unit 70 to 74 is partitioned by a partition wall 75. The coin C that has passed through the curved portion 35 of the transport path 33 by the transport belt 25 falls into any of the coin sorting sections 70 to 74 according to the diameter. Each coin sorting unit 70 to 74 has a sensor (not shown) that detects the corresponding coin C and measures the number of coins. In this coin sorting section 11, since the difference in diameter between the 5-yen coin and the 100-yen coin is small, the 5-yen coin is sorted in advance so as not to be erroneously sorted.

  The coins C that have fallen on the coin sorting units 61 and 70 to 74 slide on the guide slope 76 and are sent to the coin storage section 13. The coin storage section 13 has a plurality of storage sections provided corresponding to the coin sorting sections 61 and 70 to 74 of the coin sorting section 11, and in this embodiment, as shown in FIG. First to sixth storages corresponding to the coin sorting unit 61, 1-yen coin sorting unit 70, 50-yen coin sorting unit 71, 100-yen coin sorting unit 72, 10-yen coin sorting unit 73 and 500-yen coin sorting unit 74, respectively. It has parts 81-86. Each of the first to sixth storage portions 81 to 86 is a member that extends in the longitudinal direction XX of the second basic frame 5 and is arranged in parallel to each other in the width direction YY, and corresponds at the upstream end thereof. The coins C are received from the coin sorting units 61 and 70 to 74 to be stored, and the coins C are stored in an obliquely vertically stacked state as will be described later.

  The coin storage section 13 is connected to the coin sorting section 11 on the upstream side, and is connected to the coin dispensing section 15 that dispenses the coin C stored in the coin storage section 13 on the downstream side. As shown in FIGS. 3 and 5, the coin payout section 15 includes first to sixth payout portions 91 to 96 corresponding to the first to sixth storage portions 81 to 86, respectively. In the present embodiment, the first payout unit 91 pays out 5-yen coins stored in the first storage unit 81, and the second payout unit 92 pays out 1-yen coins stored in the second storage unit 82. The third payout unit 93 pays out 50-yen coins stored in the third storage unit 83, and the fourth payout unit 94 pays out 100-yen coins stored in the fourth storage unit 84, and the fifth payout. The unit 95 pays out 10-yen coins stored in the fifth storage unit 85, and the sixth payout unit 96 pays out 500-yen coins stored in the sixth storage unit 86.

  FIG. 5 is a perspective view showing the coin storage section 13 and the coin dispensing section 15 taken out from the second basic frame 5, and each of the storage portions 81 to 86 of the coin storage section 13 is replaced with a corresponding dispensing portion of the coin dispensing section 15. A plurality of denomination units formed by connecting integrally with 91 to 96 and arranged in parallel to each other in the width direction YY are shown. In the present embodiment, as the denomination unit, the first denomination unit 101 including the first storage unit 81 and the first payout unit 91 corresponding to the 5-yen coin, and the second storage unit 82 corresponding to the 1-yen coin. Corresponding to the second denomination unit 102 comprising the second payout unit 92 and the third denomination unit 103 comprising the third storage unit 83 and the third payout unit 93 corresponding to the 50 yen coin, and corresponding to the 100 yen coin. A fourth denomination unit 104 composed of a fourth storage unit 84 and a fourth payout unit 94, and a fifth denomination unit 105 composed of a fifth storage unit 85 and a fifth payout unit 95 corresponding to a 10 yen coin, A sixth denomination unit 106 including a sixth storage unit 86 and a sixth payout unit 96 corresponding to 500 yen coins is provided.

  Each of the denomination units 101 to 106 has the same shape. FIG. 6 is a perspective view showing only the first denomination unit 101 as a representative for ease of explanation, and FIG. 7 is an exploded view thereof. The denomination unit 101 includes the first storage unit 81 and the first payout unit 91 as described above. The first storage portion 81 has an elongated base plate 87 that extends downwardly from the upstream end toward the downstream end in the longitudinal direction XX, and a base plate that extends in the longitudinal direction XX like the base plate 87. A pair of side covers 88 attached to both edges of the 87, a pair of rail grooves 89 formed on the upper surfaces of the right edge and the left edge extending in the longitudinal direction XX of the base plate 87, and a pair of rails And a pair of laminated belts 90 that are set to be rotatable while being accommodated in the groove 89.

  Since the base plate 87 has a plate width corresponding to the diameter of the coin C (5-yen coin in this embodiment), the plate width of each base plate 87 of the first to sixth denomination units 101 to 106 is Different from each other. In the present embodiment, the width of the base plate 87 is increased in the order of the second denomination unit 102 to the sixth denomination unit 106. A space surrounded by the base plate 87 and the pair of side covers 88 is configured as a storage groove 110 in which the coins C are stored. The base plate 87 and the pair of side covers 88 are made of, for example, a steel plate. The first payout portion 91 is provided close to the downstream end of the base plate 87 of the storage portion, and has a payout belt 97 that is set to be rotatable between the pair of side covers 88. As is clear from the above, each denomination unit has its longitudinal direction aligned with the longitudinal direction XX of the second foundation frame, and its width direction coincides with the width direction YY of the second foundation frame. I'm doing it. The laminated belt 90 and the payout belt 97 are made of urethane rubber, for example.

  FIG. 8 is a schematic diagram showing an arrangement configuration of pulleys around which the laminated belt 90 and the payout belt 97 are wound. The pair of laminated belts 90 includes a pair of upstream pulleys 112 disposed in the vicinity of the upstream end of the base plate 87 and corresponding to the right edge and the left edge of the base plate 87, and the vicinity of the downstream end of the base plate 87. Between the downstream pulley 114 and the downstream pulley 114. The payout belt 97 is stretched between three first to third pulleys 114, 116, and 118 arranged in a substantially triangular shape near the downstream end of the base plate 87 of the first storage portion 81. The first pulley (driven pulley) is a common pulley formed integrally with the downstream pulley 114 of the laminated belt 90, and the payout belt 97 is a common pulley between the pair of laminated belts 90 as shown in FIG. 114 is wound around. The second pulley (driven pulley) 116 is disposed above and in front of the common pulley 114, and the third pulley (drive pulley) 118 is disposed below and slightly in front of the second pulley 116. Has been. The payout belt 97 stretched between the common pulley (first pulley) 114, the second pulley 116, and the third pulley 118 is disposed at the position where the payout belt 97 is wound around the common pulley 114 and the base plate 87 of the first storage portion 81. It faces the downstream end via a slight gap. Each of the pair of upstream pulley 112, shared pulley 114, second pulley 116 and third pulley 118 is rotatably supported by a support shaft supported by the side cover 88 between the pair of side covers 88.

  In addition, one pulley 120 and two rollers 121 and 122 arranged in the longitudinal direction XX are disposed on the left and right edges of the substantially intermediate portion on the lower surface of the base plate 87. These pulleys 120 and rollers 121 and 122 apply tension to the laminated belt 90 so that the laminated belt 90 does not loosen.

  Next, a drive mechanism that rotationally drives the laminated belt 90 and the payout belt 97 will be described. As shown in FIG. 3, a laminated motor 124 that drives the laminated belt 90 and the payout belt 97 is disposed at the right rear end of the second foundation frame 5. The laminated motor 124 has a drive shaft 126 that extends through the right side wall 5a of the second base frame 5 and extends in the width direction + Y. A drive pulley 128 is attached to the drive shaft 126 so as to be integrally rotatable. ing. A driven pulley 130 is rotatably provided at a front end portion in the longitudinal direction + X of the right side wall 5a of the second foundation frame 5 via a support shaft 131 protruding from the right side wall 5a. A driving belt 132 is stretched between the driving pulley 128 and the driven pulley 130. A tension pulley 134 is provided between the drive pulley 128 and the driven pulley 130 to apply tension to the drive belt 132 so that the drive belt 132 does not loosen. A driven gear 136 having a different diameter is attached to the driven pulley 130 so as to be integrally rotatable on the same support shaft 131. A main transmission gear 138 meshes with the driven gear 136 behind the driven gear 136 in the longitudinal direction XX.

  The support shaft 139 of the main transmission gear 138 passes through the right side wall 5a of the second foundation frame 5, extends in the width direction YY, and extends into the second foundation frame 5. Six first to sixth transmission gears 141 to 146 are attached to a portion of the support shaft 139 of the main transmission gear 138 that extends into the second basic frame 5 at a predetermined interval. Each of the first to sixth transmission gears 141 to 146 meshes with a gear portion 148 around which the payout belt 97 is not wound in the third pulley 118 of the corresponding first to sixth payout portions 91 to 96.

  When the laminated motor 124 is driven, the driving belt 132 is set to rotate counterclockwise as indicated by an arrow in FIG. Due to the counterclockwise rotation of the drive belt 132, the driven pulley 130 and the driven gear 136 connected to the driven pulley 130 so as to be integrally rotatable can also rotate counterclockwise. Accordingly, the main transmission gear 138 provided in contact with the driven gear 136 rotates clockwise. As a result, the first to sixth transmission gears 141 to 146 attached to the same support shaft 139 as the main transmission gear 138 also rotate clockwise. When the first to sixth transmission gears 141 to 146 rotate clockwise, the third pulley 118 of the first to sixth dispensing portions 91 to 96 rotates counterclockwise, so that the dispensing belt 97 rotates counterclockwise. Driven. Along with this, the laminated belt 90 wound around the common pulley 114 that is the same as the payout belt 97 is also driven to rotate counterclockwise.

  The coins C that have been sorted by the respective coin sorting units 61 and 70 to 74 and dropped to the upstream ends of the corresponding first to sixth storage units 81 to 86 are first to first rotated by the counterclockwise rotation of the laminated belt 90. It is conveyed toward the downstream end of the 6 storage parts 81-86, and contacts the discharge belt 97 of the corresponding 1st-6th discharge parts 91-96. The coin C that has come into contact with the payout belt 97 is transported so that it is picked up by the payout belt 97 that rotates counterclockwise, rides on the payout belt 97, and is blocked by a stop member 152 described later. On this first coin C, the next coin C carried by the laminated belt 90 rides and is stacked in a substantially oblique vertical state. When such a stacking operation is sequentially repeated by the subsequent coins C, the coins C are stacked while leaning against the payout belt 97 as shown in FIG.

  As shown in FIG. 8, the stop member 152 includes a solenoid main body 153 and a rod-like stop pin 154 that is built in the solenoid main body 153 so as to be able to appear and retract. FIG. 8 shows a protruding state in which the stop pin 154 protrudes from the solenoid body 153. In this projecting state, the tip of the stop pin 154 comes into contact with the edge of the coin C riding on the payout belt 97 to dam the coin C. On the contrary, when the stop pin 154 is immersed in the solenoid body 153, the stop pin 154 is pulled up to a position where it does not come into contact with the coin C, so that the coin C contacting the payout belt 97 is rotated by the rotation of the payout belt 97. By driving, it is paid out toward a coin tray 150 (FIG. 4) provided at the front end of the second basic frame 5. Further, since the laminated belt 90 continuously rotates counterclockwise, the leftmost (+ X direction) coins C in the laminated state come into contact with the payout belt 97 and the coins C are sequentially paid out one by one. The

  Further, a steel ball 156 is disposed on the front side of the stop pin 154 of the stop member 152 at a predetermined interval from the upper surface of the payout belt 97. In the state where the coin C is being conveyed by the payout belt 97, the steel ball 156 applies friction between the back surface of the coin C and the upper surface of the payout belt 97 by pressing the surface of the coin C, and the coin C and the payout belt 97. Acts as a weight to prevent slippage between 97. Thereby, the conveyance attitude | position of the coin C is stabilized.

  Next, the positioning means for the second basic frame 5 of the first to sixth denomination units 101 to 106 will be described. Each of the denomination units 101 to 106 is positioned at two positions separated from each other in the longitudinal direction XX of the second basic frame 5. First, in each of the pair of side frames 88 of the first to sixth denomination units 101 to 106, as shown in FIGS. 6 and 7, a notch 158 is formed at the lower edge near the front end (downstream end). On the other hand, as shown in FIG. 9, a positioning rod 160 extending in the width direction YY is disposed at the front end portion in the longitudinal direction XX of the second basic frame 5.

  In the present embodiment, as shown in FIG. 10, the positioning rod 160 has six first to sixth engagement grooves 161 to 166 corresponding to the six first to sixth denomination units 101 to 106. It is formed in the width direction YY. The first to sixth engaging groove portions 161 to 166 are separated from each other by a flange-shaped member 167. Each of the engaging groove portions 161 to 166 includes two engaging grooves formed so as to extend in the circumferential direction of the positioning rod 160.

  Specifically, the first engagement groove portion 161 includes an engagement groove 161a and an engagement groove 161b. The dimension Z between the engagement grooves between the engagement groove 161a and the engagement groove 161b is equal to the first denomination unit 101. It corresponds to the inner dimensions of. Similarly, the second engagement groove portion 162 includes an engagement groove 162a and an engagement groove 162b. The inter-engagement groove dimension Z between the engagement groove 162a and the engagement groove 162b is equal to that of the second denomination unit 102. It corresponds to the dimension. The third engagement groove portion 163 includes an engagement groove 163a and an engagement groove 163b, and the engagement groove dimension Z between the engagement groove 163a and the engagement groove 163b corresponds to the inner dimension of the third denomination unit 103. is doing. The fourth engagement groove portion 164 includes an engagement groove 164a and an engagement groove 164b. The engagement groove dimension Z between the engagement groove 164a and the engagement groove 164b corresponds to the inner dimension of the fourth denomination unit 104. is doing. The fifth engagement groove portion 165 includes an engagement groove 165a and an engagement groove 165b, and the engagement groove dimension Z between the engagement groove 165a and the engagement groove 165b corresponds to the inner dimension of the fifth denomination unit 105. is doing. The sixth engagement groove portion 166 includes an engagement groove 166a and an engagement groove 166b, and the engagement groove dimension Z between the engagement groove 166a and the engagement groove 166b corresponds to the inner dimension of the sixth denomination unit 106. is doing.

  The first to sixth engagement groove portions 161 to 166 are formed in the order of the first to sixth denomination units 101 to 106. Since the flange-shaped member 167 is formed to be larger than the notch 158, the side frame 88 contacts the flange-shaped member 167. As a result, the first to sixth denomination units 101 to 106 positioned at predetermined positions are fixed so as not to move in the width direction YY. Moreover, the 1st-6th money type units 101-106 are fixed so that it may not move to the longitudinal direction XX because the notch part 158 fits into the corresponding engagement grooves 161a-166b. Of course, the configuration is not limited to the configuration of the positioning rod 160 shown in the present embodiment. For example, the edge of the channel member having a U-shaped cross section is cut and the side frame 88 is cut. A configuration in which the notch 158 is fitted may be used.

  Further, as shown in the bottom view of FIG. 11, each denomination unit 101 to 106 has a lower surface of the base plate 87 in the vicinity of its upstream end, that is, at a position spaced apart from the notch 158 in the longitudinal direction XX. A locking projection 169 that protrudes from 87 b toward the bottom wall 5 c of the second foundation frame 5 is formed. On the other hand, on the bottom wall 5c of the second foundation frame 5, each denomination unit 101-106 is located in the vicinity of the rear end in the longitudinal direction XX, that is, at a position separated from the positioning rod 160 in the longitudinal direction XX. A plurality of locking holes 170 with which the locking protrusions 169 can be engaged are perforated. These locking holes 170 are shifted from each other in the width direction Y-Y of the second basic frame 5 with respect to at least one of the first to sixth denomination units 101 to 106 having different width dimensions. It is formed so as to be in a positional relationship. Correspondingly, the locking protrusions 169 of the respective denomination units 101 to 106 are also arranged in the width direction YY when the first to sixth denomination units 101 to 106 are attached to the second base frame 5 in parallel with each other. Are formed so as to have a positional relationship shifted from each other. Since each of the first type-specific unit 101 and the fourth type separation unit 104 corresponds to 5-yen coins and 100-yen coins having similar diameters, they may be used as the same denomination unit.

  The denomination units 101 to 106 first engage the notch portions 158 with the corresponding first to sixth engaging groove portions 161 to 166 of the positioning rod 160 of the second base frame 5, and then the locking projections. By engaging the protrusion tips of 169 with the corresponding locking holes 170 of the second foundation frame 5, the protrusions 169 are positioned with respect to the second foundation frame 5.

  Note that the locking protrusion 169 and the locking hole 170 are shifted from each other when the first to sixth money type units 101 to 106 attached to the second base frame 5 are viewed from the width direction YY. However, instead of this, the shapes of the locking projections 169 may be different from each other. Specifically, the locking protrusions 169 of the first to sixth denomination units 101 are protrusions having different shapes such as a triangular cross-section, a quadrangular cross-section, and a circular cross-section, for example. The hole 170 is a hole having a triangular shape, a quadrangular shape, a circular shape, or the like. According to this configuration, the first to sixth denomination units 101 to 106 can be attached to predetermined positions without forming the positions of the locking projections 169 and the locking holes 170 in the width direction YY. Can do. Note that the locking protrusion 169 and the locking hole 170 are shifted from each other when the first to sixth money type units 101 to 106 attached to the second base frame 5 are viewed from the longitudinal direction XX. You may form so that it may become.

  As shown in FIG. 12, the base plate 87 of each denomination unit 101-106 has a tongue-shaped gripping member 172 extending obliquely upward from its upstream end. Even if the first to sixth denomination units 101 to 106 are attached to the second base frame 5 without a gap by grasping the grasping member 172 by hand, the first to sixth denomination units 101 to 106 are used. Can be easily attached to and detached from the second base frame 5.

  As shown in FIG. 4, the second base frame 5 has a storage portion presser cover 174 that covers the first to sixth storage portions 81 to 86 of the first to sixth denomination units 101 to 106 from above, in the width direction. It is attached so as to be rotatable around a support shaft 175 extending in YY. Further, the second base frame 5 covers the downstream ends of the first to sixth payout portions 91 to 96 and the first to sixth storage portions 81 to 86 of the first to sixth denomination units 101 to 106 from above. A payout portion cover 176 is attached to be rotatable around a support shaft (not shown).

  FIG. 13 shows an open state of the storage portion presser cover 174 and the payout portion cover 176. A recess 178 extending in the longitudinal direction XX is formed on the lower surface 174a of the reservoir pressing cover 174 at a position corresponding to each reservoir groove 110 (FIG. 6) of the first to sixth reservoirs 81 to 86. . A cutout portion 180 into which a fitting piece 179 formed on the front surface of the payout portion cover 176 is fitted is formed at the bottom of each concave portion 178. Further, on the front side of the both side surfaces of the storage portion presser cover 174, there is provided a protruding piece 181 that is spring-biased so as to be retractable by the operation of the manual lever 185 (FIG. 4). The lever 185 is actuated to protrude from both side surfaces of the storage portion presser cover 174 and fit into fitting holes 182 formed on the inner surfaces of the both side walls 5a and 5b of the second foundation frame 5. Further, between the recesses 178 of the lower surface 174a of the storage unit presser cover 174, a storage groove 184 that contacts the upper edge 88a of the side cover 88 of the adjacent denomination unit 101 to 106 and stores the upper edge 88a is provided in the longitudinal direction X. -X extends.

  When closing the storage portion presser cover 174 and the payout portion cover 176, first, the payout portion cover 176 is rotated in the direction indicated by the arrow to thereby form the first to sixth payout portions 91 to 96 and the first to sixth storage portions. The downstream end of 81-86 is covered. Subsequently, when the storage portion presser cover 174 is rotated in the direction of the arrow, the fitting piece 179 of the payout portion cover 176 is engaged with the notch portion 180 of the storage portion presser cover 174, and the first to sixth gold types The upper edges 88a of the side covers 88 of the units 101 to 106 are accommodated in contact with the accommodation grooves 184 of the storage unit presser cover 174, and each elastic protrusion piece 181 of the storage unit presser cover 174 is elastically deformed. 2 The base frame 5 is fitted into the fitting holes 182 corresponding to both side walls 5a and 5b. Thereby, the storage part presser cover 174 can fix the 1st-6th storage parts 81-86 in a predetermined position in the state which pressed the 1st-6th storage parts 81-86 from upper direction.

  Moreover, since the storage part presser cover 174 is a dedicated member separate from the first base frame 3 that is stacked on the second base frame 5, the storage part presser cover 174 is replaced with the first to sixth storage parts. It becomes easy to mold at a size that exactly corresponds to the size of 81-86. Therefore, compared with the structure which presses the 1st-6th storage parts 81-86 with the 1st foundation frame 3 in which the coin insertion section 7, the coin conveyance section 9, the coin selection section 11, etc. are provided, it is 1st-1st. 6 storage parts 81-86 can be pressed from the upper part more correctly.

  As shown in FIG. 5, the second denomination unit 102 is provided with a pull-in belt 190 configured to be slidable on the guide slope 76. Since 1-yen coins are light, even if they are sorted by the 1-yen coin sorting unit 70 and fall on the guide slope 76, they may not slide down toward the laminated belt 90 of the second storage unit 82. Accordingly, the 1-yen coin can be forcibly passed from the 1-yen coin sorting unit 70 to the laminated belt 90 of the second storage unit 81. In addition, a presser member 192 that maintains the 1-yen coin in an obliquely vertically placed state is provided at the downstream end of the second storage unit 81. The pull-in belt 190 and the pressing member 192 may be omitted.

  As is clear from the above description, the first to sixth denomination units 101 to 106 are not molded as an integral part and are not connected to each other by a connecting member such as a screw, but are simply the second foundation. They are placed on the frame 5 in parallel with each other (in the width direction YY). In other words, the denomination units 101 to 106 are independent from each other and can be attached to and detached from the second basic frame 5 individually. Therefore, when it is necessary to replace the denomination unit, for example, the fourth denomination unit 104 corresponding to a 100 yen coin, or to replace its components (for example, the laminated belt 90 and the payout belt 97 broken by wear) In the case where it is necessary to remove 100-yen coins, foreign matters, etc. clogged in the fourth denomination unit 104, only the fourth denomination unit 104 is attached with the other denomination units attached to the second base frame 5. 2 It can be removed from the base frame 5 for repair, parts replacement, etc. Thus, since it is set as the structure which does not need to remove all the 1st-6th money type units 101-106 from the 2nd foundation frame 5 for repair, parts replacement, etc., a maintenance work does not take time.

  For example, a coin changer that handles all types of coins, and a coin that handles only 10 yen coins, 100 yen coins, and 500 yen coins. For change machines, exchange of the support shaft (positioning rod) 160 having a predetermined inter-engagement groove dimension and change of the coin sorting section, the denomination units 101 to 101 corresponding to the denominations to be sorted This can be dealt with by simply selecting 106 and attaching the selected denomination units 101 to 106 to the second base frame 5. Thus, unlike the conventional coin change machine, the coin change machine 1 of this embodiment does not need to design and manufacture the structure of the storage part and the payout part individually for all models. High nature.

  Moreover, the coin change machine 1 of this embodiment has the notch part 158 formed in each denomination unit 101-106 in the 1st-6th relationship formed in the positioning rod 160 provided in the 2nd foundation frame 5. The engaging projections 169 formed on the respective denomination units 101 to 106 are engaged with the engaging holes 170 formed on the second basic frame 5 while being engaged with the mating grooves 161 to 166. In this way, the first to sixth denomination units 101 to 106 are attached to the second base frame 5 at two positions separated from each other in the longitudinal direction XX, and therefore upstream of the denomination units 101 to 106. It is possible to prevent the end and the downstream end from moving in the longitudinal direction XX and the width direction YY.

  Furthermore, each engagement groove dimension Z of the first to sixth engagement groove portions 161 to 166 of the positioning rod 160 is set according to the inner dimension of the corresponding first to sixth money type units 101 to 106. Therefore, it can prevent attaching the 1st-6th denomination units 101-106 other than the money type selected to the 1st-6th engagement groove parts 161-166 accidentally. Therefore, the first to sixth denomination units 101 to 106 can be accurately attached to the second base frame 5 in order at predetermined positions.

  Furthermore, the locking protrusions 169 of the denomination units 101 to 106 and the locking holes 170 of the second base frame 5 with which they are engaged are formed at positions shifted from each other in the width direction YY, so that the diameter It is possible to prevent denomination units corresponding to coins having a small difference, for example, the first denomination unit 101 and the fourth denomination unit 104 corresponding to 5-yen coins and 100-yen coins from being attached to the wrong positions.

  Furthermore, the first to sixth denomination units 101 to 106 are detachably attached to the second basic frame 5, while the first to sixth denomination units 101 to 106 are simply used as the second basic frame 5. A configuration in which a driving force is applied to the payout belt 97 by the first to sixth transmission gears 141 to 146 can be obtained simply by mounting. Therefore, even if the denomination of the coin C to be handled is changed, the support shaft (positioning rod) 160 having a predetermined inter-engagement groove dimension is replaced and the coin sorting section is changed to correspond to the denomination C to be handled. By attaching only the denomination unit to the second basic frame 5, it is possible to easily cope with the denomination change.
