The above coin processing device does not require a separate dedicated gate mechanism to reject unacceptable coins (different material coins and unidentifiable coins), and has the advantage that the movable guide plate means can be simply configured to fulfill this function. However, if an unacceptable coin is detected, it is necessary to widen the course width beyond the outer diameter of the coin in order to reject it. Therefore, it takes time to widen the course width before the unacceptable coins are transported in the opposite direction again.

An object of the present invention is to provide a coin processing apparatus capable of eliminating a target coin in a short time.

In order to achieve the above object, the first aspect according to the present invention is a feed belt that contacts the coin on the upper side and rotates forward to convey the coin from the inlet side passage portion to the outlet side passage portion, and the inlet side. A pair of wall portions that guide the outer peripheral surface of the coin between the passage portion and the exit side passage portion, and the outer peripheral side of the lower surface of the coin are supported between the entrance side passage portion and the exit side passage portion. It has a pair of support portions that form drop holes between them, and an identification portion that identifies whether or not the coin is a coin to be dropped into the drop hole, and is one of the wall portions of the pair of wall portions. Has a passage width expanding portion on the exit side passage portion side that widens the distance from the other wall portion from the wall component portion on the entrance side passage portion side, and the other wall portion side has a passage width expanding portion. The coins transported to the outlet side passage portion and identified as the drop target coins by the identification portion are shifted to the passage width expanding portion side and dropped into the drop hole during transportation by the reversing feed belt. It is characterized in that a trajectory changing portion capable of advancing and retreating is provided.

According to the first aspect, when the coin is conveyed from the entrance side passage portion to the exit side passage portion by the feed belt that rotates in the normal direction, the outer peripheral surface of the coin that matches the distance between the pair of wall portions and the pair of support portions is It is guided by a pair of wall portions, the outer peripheral side of the lower surface is supported by the pair of support portions, and moves toward the exit side passage portion. Further, coins having a diameter smaller than that of the coins supported by the pair of support portions fall from the drop holes between the pair of support portions and are eliminated. Then, if there is a coin identified as a fall target coin by the identification unit among the coins conveyed to the exit side passage portion, this coin is conveyed to the entrance side passage portion side by the reversing feed belt, and the locus change portion. , The distance from the other wall portion provided on the exit side passage portion side of one wall portion is shifted to the passage width expansion portion side where the distance from the other wall portion is wider than the wall component portion on the entrance side passage portion side, and the coin is dropped into the drop hole. Therefore, it is not necessary to perform an operation of widening or returning the space between the pair of wall portions and the pair of support portions, so that the target coin can be automatically removed in a short time.

In the second aspect of the present invention, in the first aspect, the coin conveyed to the exit side passage portion and identified as the falling target coin by the identification portion and the entrance side passage portion of the coin. It is characterized by further having a control unit for advancing the trajectory changing unit between the coins adjacent to the side.

According to the second aspect, the control unit is between a coin conveyed to the exit side passage portion and identified as a coin to be dropped by the identification unit and a coin adjacent to the entrance side passage portion side of the coin. Since the locus changing portion is advanced, unnecessary dropping of coins on the entrance side passage portion side of the coins identified as the coins to be dropped can be suppressed.

In a third aspect according to the present invention, in the first or second aspect, the drop hole is supported between the pair of support portions, which is conveyed from the inlet side passage portion by the feed belt that rotates in the normal direction. An inlet-side drop hole for dropping impossible small-diameter coins and an outlet-side drop for dropping coins transported from the exit-side passage by the reversing feed belt and shifted to the passage width expansion side at the trajectory changing portion. It has a hole portion, and the inlet side drop hole portion and the outlet side drop hole portion are characterized in that coins are removed at different positions.

According to the third aspect, a small-diameter coin that cannot be supported between the pair of support portions, which is conveyed from the inlet side passage portion by the feed belt that rotates in the normal direction, is dropped into the inlet side drop hole portion. On the other hand, coins that are conveyed from the exit side passage by the reversing feed belt and shifted to the passage width expansion side by the locus change part are dropped into the exit side drop hole, and are eliminated at a position different from the small diameter coin. Will be done. Therefore, the work of separating after exclusion becomes unnecessary.

A fourth aspect according to the present invention is, in any one of the first to third aspects, a state in which the passage width expanding portion makes the distance from the other wall portion equal to that of the wall constituent portion. It is characterized in that it can be switched to a state in which it is wider than the wall component.

According to the fourth aspect, the passage width expanding portion can be switched between a state in which the distance from the other wall portion is equal to that of the wall constituent portion and a state in which the passage width is wider than the wall constituent portion. By making the distance from the wall part equal to that of the wall component part, coins that match the distance between the pair of wall parts and the pair of support parts, which are transported from the entrance side passage part to the exit side passage part, are mistakenly inserted. It is possible to prevent the coin from falling into the drop hole. Further, the passage width expanding portion can drop coins from the exit side passage portion into the drop hole by setting the distance from the other wall portion to be wider than that of the wall constituent portion.

In the fifth aspect of the present invention, in the fourth aspect, the passage width expanding portion is directly driven and controlled by electric power, and the distance from the other wall portion is equivalent to that of the wall constituent portion. It is characterized in that it can be switched between a state in which the wall is set and a state in which the wall is wider than the wall component.

According to the fifth aspect, the passage width expanding portion is directly driven and controlled by electric power to make the distance to the other wall portion equal to that of the wall constituent portion and to be wider than the wall constituent portion. Since it can be switched to the state, the switching can be performed smoothly.

In the sixth aspect of the present invention, in the fourth aspect, the passage width expanding portion is urged by an urging means to make the distance from the other wall portion equal to that of the wall constituent portion. By being conveyed by the reversing feed belt and pressed by the coins shifted toward the passage width expanding portion at the locus changing portion, the coins are pressed against the urging force of the urging means to the other wall portion. It is characterized in that the distance is wider than that of the wall component.

According to the sixth aspect, the passage width expanding portion is urged by the urging means so that the distance from the other wall portion is equal to that of the wall constituent portion, and is conveyed by the reversing feed belt to change the trajectory. Since the portion is pressed by the coin shifted to the passage width expanding portion side, the distance from the other wall portion is increased against the urging force of the urging means, so that the cost is low.

The present invention can provide a coin processing apparatus capable of eliminating a target coin in a short time.

It forms a straight line along the extending direction of the passage. The end surface 106 of the support portion 103 overlaps the wall surfaces 151 to 153 of the movable wall 83 at a position in the passage extending direction. Therefore, the width of the portion of the end surface 106 that overlaps with the wall surfaces 152 and 153 is wider than the width of the portion of the end surface 106 that overlaps with the wall surface 151 in the passage width direction.

The transport path 60 has an exit-side aisle 112 whose upper surface 111 is arranged on the same plane as the upper surfaces 62, 102, 104 on the side opposite to the inlet-side aisle 61 with respect to the pair of support portions 101, 103. There is. Here, the portion surrounded by the entrance side passage portion 61, the pair of support portions 101, 103, and the exit side passage portion 112 is the drop hole 115. Therefore, the pair of support portions 101 and 103 form a drop hole 115 between them.

Since the wall surfaces 151 to 154 of the movable wall 83 are on the side opposite to the fixed wall 73 from the drop hole 115 in the passage width direction, the passage width expansion portion 162 is a drop hole from the wall surface 151 of the wall constituent portion 161. It is dented in the opposite direction to 115. The wall surfaces 151 to 153 of the movable wall 83 overlap the drop hole 115 with the position in the passage extending direction, and the wall surface 154 does not overlap the drop hole 115 with the position in the passage extending direction. A part of the passage width expanding portion 162 including the wall surfaces 152 and 153 on the entrance side passage portion 61 side overlaps the position of the drop hole 115 in the passage extending direction.

The drop hole 115 is connected to the discharge port 25 shown in FIG. 1, and coins that have fallen into the drop hole 115 are discharged from the discharge port 25 into the exclusion box 26. The pair of wall portions 63, 64 guides the outer peripheral surface of the coin C between the entrance side passage portion 61 and the exit side passage portion 112. The pair of support portions 101 and 103 support the outer peripheral side of the lower surface of the coin between the inlet side passage portion 61 and the outlet side passage portion 112. The passage width expanding portion 162 is provided in the exit side passage portion 112 of the wall portion 64.

The entrance side passage portion 61 is provided with an identification sensor 165 (identification portion) for identifying coins passing between the pair of wall portions 63 and 64 on the wall portion 63 side in the vicinity of the drop hole 115. The identification sensor 165 is a magnetic sensor that identifies the material, that is, the denomination of a coin by detecting the magnetic properties of the coin.

An elevating downstream stopper 171 is provided in the vicinity of the wall surface 72 of the fixed wall 73 of the wall portion 63 above the exit side passage portion 112 on the side opposite to the entrance side passage portion 61. The downstream stopper 171 is arranged on the side opposite to the entrance side passage portion 61 with respect to the passage width expanding portion 162 in the passage extending direction. The downstream stopper 171 provided on the wall portion 63 side is driven by the stopper solenoid 172 shown in FIG. 3 to move up and down.

The downstream stopper 171 is in the standby state in the ascending state, and when it is driven by the stopper solenoid 172 from the standby state and descends, the contact portion 173 below the lower stopper 173 is a coin that is a moving range of coins moving on the transport path 60. It advances within the moving range and can come into contact with the outer peripheral surface of the coin, and in the passage width direction, it protrudes from the wall surface 72 side of the fixed wall 73 toward the movable wall 83 side rather than the wall surface 72.

Further, when the downstream stopper 171 is driven by the stopper solenoid 172 to rise and enter the standby state, the downstream stopper 171 is retracted from the coin moving range on the transport path 60 and cannot come into contact with the coin. The downstream stopper 171 and the stopper solenoid 172 are capable of advancing and retreating with respect to the coin movement range on the transport path 60, and constitute a movement regulation unit 174 shown in FIG. 3 that advances within the coin movement range and regulates the movement of coins. ing.

Above the entrance side passage portion 61 side of the exit side passage portion 112, an elevating and lowering upstream side stopper 176 is provided near the wall surface 72 of the fixed wall 73 of the wall portion 63. Therefore, the upstream side stopper 176 is arranged closer to the inlet side passage portion 61 than the downstream side stopper 171 in the passage extending direction. The distance between the upstream stopper 176 and the downstream stopper 171 is set to a length that allows only one maximum diameter coin to be fastened between them. The two downstream stoppers 171 and the upstream stopper 176 are arranged side by side on the wall surface 72 side of the fixed wall 73.

The upstream side stopper 176 overlaps the position in the passage extending direction with the wall surface 153 of the passage width expanding portion 162, and the passage width expanding portion 162 is substantially centered on the upstream side stopper 176 on both sides in the passage extending direction. It has spread. The upstream stopper 176 overlaps the support portion 101 and the drop hole 115 at positions in the passage extending direction. The upstream stopper 176 provided on the wall portion 63 side is driven by the stopper solenoid 177 shown in FIG. 3 to move up and down.

The upstream stopper 176 is in the standby state in the ascending state, and when it is driven by the stopper solenoid 177 from the standby state and descends, the contact portion 178 at the lower portion advances within the coin movement range on the transport path 60, and the coins In addition, the wall surface 72 of the fixed wall 73 protrudes from the end surface 105 of the support portion 101 toward the movable wall side 83 in the passage width direction. The notch depth of the passage width expanding portion 162, that is, the distance between the wall surface 153 and the wall surface 151 of the wall constituent portion 161 in the passage width direction is the amount of protrusion of the contact portion 178 from the wall surface 72 of the fixed wall 73 in the passage width direction. It is set as above.

Further, when the upstream stopper 176 is driven by the stopper solenoid 177 and rises to the standby state, the upstream stopper 176 is retracted from the coin moving range on the transport path 60 and cannot come into contact with the coin. The upstream stopper 176 and the stopper solenoid 177 can advance and retreat with respect to the coin movement range on the transport path 60, and advance within the coin movement range to change the coin movement trajectory with respect to the linear trajectory along the feed belt 35. The locus changing unit 179 shown in FIG. 3 is configured.

The structure may be such that the coin moves forward and backward with respect to the coin movement range on the transport path 60. Alternatively, the structure may be such that the coin moves forward and backward with respect to the coin movement range on the transport path 60 by protruding or retracting from the wall surface 72 of the fixed wall 73 to the movable wall side 83.

The feed belt 35 described above is separated from the rotating disk 14 one by one by a sorting ring 34 and comes into contact with a coin drawn out on the entrance side passage portion 61 on the upper side, and the coins are brought into contact with the pair of wall portions 63, 64. It is conveyed from the inlet 91 side toward the drop hole 115, and if it does not fall through the drop hole 115, it is further conveyed toward the exit side passage portion 112.

In the feed belt 35 and the transport motor 55, the rotation direction in which the coins are conveyed from the inlet side passage portion 61 toward the outlet side passage portion 112 is set to the normal rotation, and the coins are transmitted in the opposite direction to the outlet side passage portion 112. The rotation direction of transporting the coin from the portion 112 toward the entrance side passage portion 61 is reversed. In the rotary disk 14 and the feeding motor 15, the rotation direction in which the coin is fed from the rotary disk 14 toward the entrance side passage portion 61 is set to normal rotation, and the coin is returned from the entrance side passage portion 61 in the opposite direction. The direction of rotation in which the coins are received by the rotating disk 14 is reversed.

In the transport path 60, coins from the rotating disk 14 that rotates in the normal direction are placed on the upper surface 62 of the entrance side passage portion 61, and the wall surface 72 of the fixed wall 73 of the pair of wall portions 63 and 64 and the wall constituent portion of the movable wall 83. It will be extended toward the wall surface 151 of 161. Then, the feed belt 35 that rotates in the normal direction comes into contact with the coin drawn out on the upper surface 62 of the entrance side passage portion 61 from the upper side, and moves along the transport path 60. At that time, the outer peripheral surface of the coin to be counted is guided by the wall surface 72 of the fixed wall 73 of the pair of wall portions 63 and 64 and the wall surface 151 of the wall constituent portion 161 of the movable wall 83, and the lower surface thereof is formed. It moves linearly along the feed belt 35 from above the upper surface 62 of the entrance side passage portion 61, above the upper surfaces 102, 104 of the pair of support portions 101, 103, and further above the upper surface 111 of the exit side passage portion 112. At that time, the pair of support portions 101 and 103 support the outer peripheral side of the lower surface of the coin with the upper surfaces 102 and 104.

In this way, the feed belt 35 and the transport path 60 transport the coins from the inlet side aisle portion 61 side toward the exit side aisle portion 112 side. In other words, the coin is supported by the inlet-side aisle portion 61, the pair of support portions 101, 103, and the outlet-side aisle portion 112 of the transport path 60, and is moved by the drive of the feed belt 35. At that time, the pair of wall portions 63 and 64 guide the outer peripheral surface of the coin, and the pair of support portions 101 and 103 support the outer peripheral side of the lower surface of the coin.

The moving positions of the movable wall 83 and the support portion 103 are adjusted by the spacing changing mechanism 121 including the electric spacing changing motor 120 shown in FIG. The control unit 38 controls the interval changing mechanism 121 according to the rotation position of the course width adjusting knob 31 to change the distance between the pair of wall portions 63 and 64 and the distance between the pair of support portions 101 and 103. When the distance between the pair of wall portions 63 and 64 and the distance between the pair of support portions 101 and 103 are maximized, the interval changing mechanism 121 maximizes the distance between the pair of wall portions 63 and 64 and the pair of support portions 101, The distance between 103 is the distance at which a 500-yen coin can be dropped into the drop hole 115.

The fixed wall 73 and the support portion 101 form the course guide wall 131, the movable wall 83 and the support portion 103 form the course guide wall 132, and the course guide walls 131 and 132 are designated counting targets. It constitutes a selection course 133 of a small diameter coin exclusion method that excludes coins having a diameter smaller than that of the denomination. The sorting course 133 is configured such that the course guide wall 132 is electrically movable in the passage width direction. As described above, the coin processing device 11 is a small-diameter coin exclusion method that excludes coins having a diameter smaller than the coins of the denomination to be counted by the sorting course 133, and is a sorting course according to the outer diameter of the coins of the denomination to be counted. The course width of 133 is configured to be variable.

When the rotation position of the course width adjusting knob 31 is the position of a 500-yen coin as a coin of the denomination to be counted (that is, when a 500-yen coin is designated as the denomination to be counted), the control unit 38 is set to the interval. A 500-yen coin is used to set the distance between the wall surface 72 of the fixed wall 73 and the wall surface 151 of the wall component 161 of the movable wall 83 and the distance between the end faces 105 and 106 of the pair of support portions 101 and 103 by the changing mechanism 121. The distance is such that a 10-yen coin is allowed to pass through the drop hole 115 without being dropped into the drop hole 115. At this time, the distance between the wall surfaces 72 and 151 is slightly larger than the diameter of the 500-yen coin. Then, the width of the entrance 91, which is equal to the distance between the wall surfaces 72 and 151, is also slightly larger than the diameter of the 500-yen coin, which is the coin of the denomination to be counted.

As a result, the 500-yen coin, which is the coin of the denomination to be counted, is supported by the pair of support portions 101 and 103, while the smaller diameter 10-yen coin, 100-yen coin, 5-yen coin, 50-yen coin, and 1-yen coin. Etc. are dropped into the drop hole 115. That is, the course guide walls 131 and 132 pass the 500-yen coins into the drop hole 115 without dropping them, and the coins having a smaller diameter are dropped into the drop hole 115, which is an interval corresponding to the counting of 500-yen coins. .. In this state, for coins having a diameter larger than that of the 500-yen coin, the inlet roller 71 and the guide wall 81 constituting the inlet 91 are in contact with the coin to restrict the movement in the direction away from the rotating disk 14. ..

Here, when the course guide walls 131 and 132 have an interval corresponding to the counting of 500-yen coins, the exit-side passage portion 112 has a 500-yen coin identified as appropriate by the identification sensor 165 and the same degree. Exclusion target coins (coins made of a material different from the 500-yen coins and unidentifiable coins) that have an outer diameter and are not identified as 500-yen coins by the identification sensor 165 will move. When the course guide walls 131 and 132 are spaced at intervals corresponding to the counting of 500-yen coins, the movable wall 83 of the course guide wall 132 is positive due to the contact portion 173 of the lowered downstream stopper 171 of the movement restricting portion 174. The movement of the coins to be excluded by the drive of the rolling feed belt 35 from the exit side passage portion 112 to the side opposite to the entrance side passage portion 61 is restricted.

Further, when the course guide walls 131 and 132 have an interval corresponding to the counting of 500-yen coins, the movable wall 83 of the course guide wall 132 reverses with the lowered upstream stopper 176 of the trajectory changing portion 179. While allowing the coins to be excluded by the carrying force of 35 to move from the exit side passage portion 112 to the entrance side passage portion 61 side, the locus of the movement is in the passage width direction with respect to the linear locus along the feed belt 35. Change to shift to. That is, the movement locus of the coin to be excluded from the exit side passage portion 112 to the entrance side passage portion 61 side is eliminated by the contact portion 178 of the upstream stopper 176 from the left side in the traveling direction of the coin to be excluded. The target coin is shifted to the right and changed so as to enter the passage width expanding portion 162 on the upper surface 104 of the supporting portion 103. Then, the end of the coin to be excluded on the fixed wall 73 side in the passage width direction is located closer to the movable wall 83 than the end surface 105 of the support portion 101, and the center of gravity is within the range of the drop hole 115 in the passage width direction. Will be located.

After that, the coins to be excluded, which have the same outer diameter as the 500-yen coin and were not identified as the 500-yen coin, are conveyed by the reversing feed belt 35 and the position in the passage extending direction is the position of the drop hole 115. At this point, the support portions 101 and 103 are separated from the support portion 101 and are supported only by the support portion 103 without being supported by the support portion 101. As a result, the coins to be excluded are inclined with respect to the horizontal so that the support portion 101 side in the passage width direction enters the drop hole 115, and finally the coins are separated from the support portion 103 and fall into the drop hole 115. .. The exclusion target coin is a drop target coin into the drop hole 115, and the identification sensor 165 identifies whether or not the coin is a drop target coin into the drop hole 115.

When the rotation position of the course width adjusting knob 31 is the position of the 10-yen coin as the coin of the denomination to be counted (that is, when the 10-yen coin is designated as the denomination to be counted), the control unit 38 is set to the interval. A 10-yen coin is used to determine the distance between the wall surface 72 of the fixed wall 73 and the wall surface 151 of the wall component 161 of the movable wall 83 and the distance between the end faces 105 and 106 of the pair of support portions 101 and 103 by the changing mechanism 121. The distance is set so that a 100-yen coin can be passed through the drop hole 115 without being dropped and the 100-yen coin can be dropped into the drop hole 115. At this time, the distance between the wall surfaces 72 and 151 is smaller than the diameter of the 500-yen coin and slightly larger than the diameter of the 10-yen coin. Then, the width of the entrance 91, which is equal to the distance between the wall surfaces 72 and 151, is also smaller than the diameter of the 500-yen coin and slightly larger than the diameter of the 10-yen coin, which is the coin of the denomination to be counted.

As a result, the 10-yen coin, which is the coin of the denomination to be counted, is supported by the pair of support portions 101 and 103, while the 100-yen coin, the 5-yen coin, the 50-yen coin, the 1-yen coin, etc. having a smaller diameter are dropped holes. Drop it on 115. That is, the course guide walls 131 and 132 pass the 10-yen coins into the drop hole 115 without dropping them, and the coins having a smaller diameter are dropped into the drop hole 115 at intervals corresponding to the counting of the 10-yen coins. .. In this state, for a 500-yen coin or the like having a diameter larger than that of the 10-yen coin, the inlet roller 71 and the guide wall 81 constituting the entrance 91 come into contact with each other and move away from the rotating disk 14. To regulate.

The coins to be excluded, which have an outer diameter and are not identified as 10-yen coins by the identification sensor 165, will move. When the course guide walls 131 and 132 are spaced so as to correspond to the counting of 10-yen coins, the movable wall 83 of the course guide wall 132 is positive due to the contact portion 173 of the lowered downstream stopper 171 of the movement restricting portion 174. The movement of the coins to be excluded by the drive of the rolling feed belt 35 from the exit side passage portion 112 to the side opposite to the entrance side passage portion 61 is restricted.

Further, when the course guide walls 131 and 132 have an interval corresponding to the counting of 10-yen coins, the movable wall 83 of the course guide wall 132 reverses with the lowered upstream stopper 176 of the trajectory changing portion 179. While allowing the coins to be excluded by the carrying force of 35 to move from the exit side passage portion 112 to the entrance side passage portion 61 side, the locus of the movement is in the passage width direction with respect to the linear locus along the feed belt 35. Change to shift to. That is, the movement locus of the coin to be excluded from the exit side passage portion 112 to the entrance side passage portion 61 side is set by the contact portion 178 of the upstream stopper 176 in the passage width expansion portion 162 on the upper surface 104 of the support portion 103. Change to get in. Then, the coins to be excluded will fall into the drop hole 115 in the same manner as described above.

When the rotation position of the course width adjusting knob 31 is the position of a 100-yen coin as the coin of the denomination to be counted (that is, when the 100-yen coin is designated as the denomination to be counted), the control unit 38 is set to the interval. A 100-yen coin is used to set the distance between the wall surface 72 of the fixed wall 73 and the wall surface 151 of the wall component 161 of the movable wall 83 and the distance between the end faces 105 and 106 of the pair of support portions 101 and 103 by the changing mechanism 121. The distance is such that a 5-yen coin is allowed to pass through the drop hole 115 without being dropped and the 5-yen coin is dropped into the drop hole 115. At this time, the distance between the wall surfaces 72 and 151 is smaller than the diameter of the 10-yen coin and slightly larger than the diameter of the 100-yen coin. Then, the width of the entrance 91, which is equal to the distance between the wall surfaces 72 and 151, is also smaller than the diameter of the 10-yen coin and slightly larger than the diameter of the 100-yen coin, which is the coin of the denomination to be counted.

When the rotation position of the course width adjusting knob 31 is the position of the 5-yen coin as the coin of the denomination to be counted (that is, when the 5-yen coin is designated as the denomination to be counted), the control unit 38 is set to the interval. A 5-yen coin is used to set the distance between the wall surface 72 of the fixed wall 73 and the wall surface 151 of the wall component 161 of the movable wall 83 and the distance between the end faces 105 and 106 of the pair of support portions 101 and 103 by the changing mechanism 121. The distance is such that a 50-yen coin is allowed to pass through the drop hole 115 without being dropped into the drop hole 115. At this time, the distance between the wall surfaces 72 and 151 is smaller than the diameter of the 100-yen coin and slightly larger than the diameter of the 5-yen coin.

A 50-yen coin is used to set the distance between the wall surface 72 of the fixed wall 73 and the wall surface 151 of the wall component 161 of the movable wall 83 and the distance between the end faces 105 and 106 of the pair of support portions 101 and 103 by the changing mechanism 121. The distance is such that a 1-yen coin is allowed to pass through the drop hole 115 without being dropped, and the 1-yen coin is dropped into the drop hole 115. At this time, the distance between the wall surfaces 72 and 151 is smaller than the diameter of the 5-yen coin and slightly larger than the diameter of the 50-yen coin.

When the rotation position of the course width adjusting knob 31 is the position of the 1-yen coin as the coin of the denomination to be counted (that is, when the 1-yen coin is designated as the denomination to be counted), the control unit 38 is set to the interval. A 1-yen coin is used to determine the distance between the wall surface 72 of the fixed wall 73 and the wall surface 151 of the wall component 161 of the movable wall 83 and the distance between the end faces 105 and 106 of the pair of support portions 101 and 103 by the changing mechanism 121. The distance is set so that a coin having a diameter smaller than that of a 1-yen coin can be dropped into the drop hole 115 without being dropped into the drop hole 115. At this time, the distance between the wall surfaces 72 and 151 is smaller than the diameter of the 50-yen coin and slightly larger than the diameter of the 1-yen coin. Then, the width of the entrance 91, which is equal to the distance between the wall surfaces 72 and 151, is also smaller than the diameter of the 50-yen coin and slightly larger than the diameter of the 1-yen coin, which is the coin of the denomination to be counted.

As a result, the 1-yen coin, which is the coin of the denomination to be counted, is supported by the pair of support portions 101 and 103, while the coin having a smaller diameter is dropped into the drop hole 115. That is, the course guide walls 131 and 132 pass the 1-yen coins into the drop hole 115 without dropping them, and the coins having a smaller diameter are dropped into the drop hole 115 at intervals corresponding to the counting of the 1-yen coins. .. In this state, for 500-yen coins, 10-yen coins, 100-yen coins, 5-yen coins, 50-yen coins, etc., which have a diameter larger than that of 1-yen coins, the entrance roller 71 and the guide wall 81 constituting the entrance 91 Is in contact with the coin and restricts its movement in the direction away from the rotating disk 14.

Here, when the course guide walls 131 and 132 are spaced at intervals corresponding to the counting of 1-yen coins, the exit-side passage portion 112 has the same level as the 1-yen coins identified as appropriate by the identification sensor 165. The coins to be excluded, which have an outer diameter and are not identified as 1-yen coins by the identification sensor 165, will move. When the course guide walls 131 and 132 are spaced at intervals corresponding to the counting of 1-yen coins, the movable wall 83 of the course guide wall 132 is positive due to the contact portion 173 of the lowered downstream stopper 171 of the movement restricting portion 174. The movement of the coins to be excluded by the drive of the rolling feed belt 35 from the exit side passage portion 112 to the side opposite to the entrance side passage portion 61 is restricted.

Further, when the course guide walls 131 and 132 have an interval corresponding to the counting of 1-yen coins, the movable wall 83 of the course guide wall 132 reverses with the lowered upstream stopper 176 of the trajectory changing portion 179. While allowing the coins to be excluded by the carrying force of 35 to move from the exit side passage portion 112 to the entrance side passage portion 61 side, the locus of the movement is in the passage width direction with respect to the linear locus along the feed belt 35. Change to shift to. That is, the movement locus of the coin to be excluded from the exit side passage portion 112 to the entrance side passage portion 61 side is set by the contact portion 178 of the upstream stopper 176 in the passage width expansion portion 162 on the upper surface 104 of the support portion 103. Change to get in. Then, the coins to be excluded will fall into the drop hole 115 in the same manner as described above.

As described above, the locus changing portion 179 having the upstream side stopper 176 provided on the wall portion 63 side so as to be able to advance and retreat receives the coins conveyed to the exit side passage portion 112 and identified as the coins to be dropped by the identification sensor 165. During the transfer by the reverse feed belt 35, the passage width is shifted to the 162 side and dropped into the drop hole 115.

The notch length of the passage width expanding portion 162 in the passage extending direction is set so as to have a length of about one coin before and after the position facing the upstream stopper 176 in the passage width direction. ing. However, since the coin is circular, and it is sufficient that the coin can be conveyed while being shifted in the passage width direction by the upstream stopper 176, the length of one coin is not always necessary.

In other words, the size of the passage width expanding portion 162 is equal to the diameter of the maximum diameter coin centered on the point where the maximum diameter coin to be handled contacts the upstream stopper 176 that comes into contact during transportation by the reversing feed belt 35. Since it draws a trajectory, it should be large enough to accept this. Then, after drawing a locus equal to the diameter of the maximum diameter coin just beside the upstream stopper 176 in the passage width direction, the passage width expanding portion 162 extends the passage so that the coin can move in the passage extending direction. It suffices if it extends in the direction of presence. In that state, in order for the coin to surely fall into the drop hole 115, it is sufficient that the notch having the length of one maximum diameter coin is in the passage extending direction of the passage width expanding portion 162.

In the entrance side passage portion 61, a stagnant coin detection sensor 125 that detects coins C stagnant on the inlet 91 side of the pair of wall portions 63, 64 as shown in FIG. 4 is provided in the vicinity of the inlet roller 71 of the wall portion 63. It is provided. When the time for continuously detecting the same coin reaches a predetermined time while the feed belt 35 is rotating, the stagnant coin detection sensor 125 has a coin C that stays on the inlet 91 side of the wall portions 63 and 64. On the other hand, if the time for continuously detecting the same coin does not reach a predetermined time, it is detected that there is no coin C staying on the inlet 91 side of the wall portions 63 and 64.

The stagnant currency detection sensor 125 is, for example, an optical transmission type sensor, and includes light emitting elements and light receiving elements arranged on both upper and lower sides with respect to the upper surface 62 of the entrance side passage portion 61. The stagnant coin detection sensor 125 is in an on state in which the light receiving element does not receive light from the light emitting element, and is in a state of detecting the presence of coins, and in an off state in which the light receiving element receives light from the light emitting element, there is no coin. Is in the state of being detected.

The stagnant coin detection sensor 125 turns on and off for less than a predetermined time in a situation where coins of the denomination to be counted and small diameter coins having a smaller diameter are sequentially sent between the course guide walls 131 and 132. However, if a large-diameter coin with a larger diameter than the coin of the denomination to be counted stops at the entrance 91 without being sent between the course guide walls 131 and 132, it will remain on for a predetermined time or longer. .. Based on the detection result of the staying coin detection sensor 125, the control unit 38 is in a state where a large-diameter coin C is staying in the vicinity of the entrance 91 of the sorting course 133 (that is, the coin C is not taken into the sorting course 133). It is determined whether or not the state is clogged. As the staying currency detection sensor 125, it is possible to use an optical reflection type sensor, and it is also possible to use one magnetic sensor.

The outlet-side aisle portion 112 is provided with a count sensor 181 that counts coins moving on the exit-side aisle portion 112 during transportation by the feed belt 35 on the side opposite to the inlet-side aisle portion 61. The count sensor 181 is provided in the vicinity of the wall surface 72 of the fixed wall 73 in the passage width direction. The count sensor 181 is, for example, an optical transmission type sensor, and includes light emitting elements and light receiving elements arranged on both upper and lower sides with respect to the upper surface 111 of the exit side passage portion 112. The count sensor 181 detects that there are coins when the light receiving element does not receive light from the light emitting element, and detects that there are no coins when the light receiving element receives light from the light emitting element. It will be in a state of doing. The count sensor 181 changes from the off state to the on state, and when it is turned off again, detects that one coin has passed. As the count sensor 181, it is possible to use an optical reflection type sensor, and it is also possible to use one magnetic sensor.

When counting coins by the coin processing device 11, the operator rotates the course width adjusting knob 31 to the position of the coin of the counting target denomination to be counted. For example, when counting 100-yen coins as coins of the denomination to be counted, the course width adjustment knob 31 is aligned with the position of the 100-yen coins. Then, the operator opens the hopper cover 13, inserts a 100-yen coin into the hopper 12, and inputs the start operation of the operation display unit 30.

Then, the control unit 38 appropriately drives the interval changing motor 120 on condition that the hopper sensor 16 detects coins, and the interval changing mechanism 121 sets the distance between the course guide walls 131 and 132, that is, the interval. The distance corresponding to the counting of 100-yen coins, which are coins of the denomination to be counted, that is, the distance between the wall surface 72 of the fixed wall 73 and the wall surface 151 of the wall constituent portion 161 of the movable wall 83, and the pair of support portions 101, 103. The distance between the end faces 105 and 106 is defined as the distance at which the 100-yen coin is passed through the drop hole 115 without being dropped and the 5-yen coin is dropped into the drop hole 115. At this time, the distance between the wall surfaces 72 and 151 is smaller than the diameter of the 10-yen coin and slightly larger than the diameter of the 100-yen coin, and the width of the inlet 91 is also smaller than the diameter of the 10-yen coin. It is slightly larger than the diameter of a 100-yen coin, which is a coin. That is, when counting coins, the control unit 38 fixes the sorting course 133 in advance to a course width that matches the outer diameter of the denomination to be counted. After that, the control unit 38 starts the forward rotation of the feeding motor 15 and the transport motor 55. Then, the rotating disk 14 constituting the lower part of the hopper 12 rotates forward, and the feed belt 35 rotates forward. At this time, both the downstream stopper 171 and the upstream stopper 176 are in the raised standby state.

Due to the centrifugal force of the rotating disk 14 that rotates in the normal direction, the coins in the hopper 12 are fed out to the entrance side passage portion 61 of the transport path 60 while being separated one by one by the sorting ring 34, and the coins in the feed belt 35 rotate in the normal direction. Move towards the sorting course 133. That is, coins are sent from the hopper 12 to the transport path 60 side from the inlet 91, and are transported toward the course guide walls 131 and 132 constituting the sorting course 133.

Then, the 100-yen coin moves on the entrance side passage portion 61 by the forward rotation drive of the feed belt 35, and is detected by the stagnant coin detection sensor 125 at the entrance 91. After that, the 100-yen coin is conveyed on the course guide walls 131 and 132 while being guided by the outer peripheral surfaces of the wall surfaces 72 and 151 of the wall portions 63 and 64, and after being identified by the identification unit 165, the support portions 101 and 103. The outer peripheral side of the lower surface is supported by the upper surfaces 102 and 104, moves to the exit side passage portion 112 side downstream of the sorting course 133, and is counted by the count sensor 181 provided in the outlet side passage portion 112. At this time, if a 5-yen coin, a 50-yen coin, a 1-yen coin, or the like having a diameter smaller than the 100-yen coin, which is the coin of the denomination to be counted, is mixed in the hopper 12, the small-diameter coin is a course guide wall. Instead of being supported by the support portions 101 and 103 of 131 and 132, the coin falls from the drop hole 115 and is discharged from the discharge port 25 to the exclusion box 26.

During the forward rotation drive of the rotating disk 14 and the feed belt 35, the control unit 38 counts the coins identified as 100-yen coins by the identification sensor 165 by the count sensor 181 and releases them to the chute 19. On the other hand, during the forward rotation drive of the feed belt 35, the following exclusion control is performed on the coins that are not identified as 100-yen coins by the identification sensor 165, that is, the coins to be dropped into the drop hole 115.

That is, based on the timing when the identification sensor 165 detects the coin to be dropped, the downstream stopper 171 that has been in the standby state until then is lowered by the drive of the stopper solenoid 172, and the contact portion 173 is the coin on the transport path 60. Advance within the range of movement. At the same time, based on the timing when the identification sensor 165 detects the coin to be dropped, the upstream stopper 176, which has been in the standby state until then, is lowered by the drive of the stopper solenoid 177, and the contact portion 178 is moved on the transport path 60. Advance within the coin movement range. That is, since the distance between the identification sensor 165 and each of the upstream stopper 176 and the downstream stopper 171 is the default and the transport speed of the feed belt 35 is the default, the identification sensor 165 detects the coin to be dropped. Based on the timing, the upstream stopper 176 and the downstream stopper 171 are operated so as to advance within the coin movement range on the transport path 60 in a predetermined positional relationship with respect to the coin.

Here, the timing of driving the stopper solenoid 172 is such that the falling target coin having the same outer diameter as the 100-yen coin, which is conveyed by the feed belt 35 that rotates in the normal direction, exceeds the contact portion 173 of the downstream stopper 171. It is a timing at which the movement to the side opposite to the entrance side passage portion 61 can be regulated by the contact portion 173 of the downstream stopper 171 and the movable wall 83. As a result, the downstream stopper 171 stops the falling target coin when the contact portion 173 enters between the falling target coin and the 100-yen coin adjacent to the side opposite to the entrance side passage portion 61 of the falling target coin. Let me.

Further, the timing of driving the stopper solenoid 177 is such that the falling target coin having the same outer diameter as the 100-yen coin, which is conveyed by the feed belt 35 that rotates in the normal direction, exceeds the contact portion 178 of the upstream stopper 176. The coin moves to the side opposite to the entrance side passage portion 61, and the subsequent coins adjacent to the entrance side passage portion 61 side of the coin to be dropped pass the contact portion 178 of the upstream stopper 176 to the entrance side. It is a timing at which the movement to the opposite side of the passage portion 61 can be regulated by the contact portion 178 of the upstream stopper 176. As a result, the contact portion 178 of the upstream stopper 176 is inserted between the falling target coin having the same outer diameter as the 100-yen coin and the coin adjacent to the entrance side passage portion 61 side of the falling target coin.

That is, the control unit 38 that controls the drive timing of the stopper solenoid 177 is a coin conveyed to the exit side passage portion 112 and identified as a coin to be dropped by the identification sensor 165, and the inlet side passage portion 61 side of the coin. The upstream stopper 176 of the locus changing portion 179 is advanced between the following coins adjacent to the coin, and the following coins are stopped.

In other words, a coin identified as a falling target coin with an outer diameter similar to that of a 100-yen coin is sandwiched between two downstream stoppers 171 and upstream stoppers 176 to separate it from the preceding coin and also with the succeeding coin. To separate.

Here, if the coin to be dropped is not detected at the timing that should be detected by the count sensor 181, the coin to be dropped is a coin having a diameter smaller than that of the 100-yen coin, and is from the inlet side passage portion 61 to the exit side passage portion 112. It is determined that the coin has fallen into the drop hole 115 during the transfer of the coin, and the stopper solenoids 172 and 177 are driven for the coin to be dropped to move the downstream stopper 171 and the upstream stopper 176 on the transport path 60. By retracting from the range, the exclusion control is terminated and the subsequent coins are counted.

In addition to advancing the upstream stopper 176 and the downstream stopper 171 into the coin movement range based on the detection timing by the coin identification sensor 165 of the falling target coin, the count sensor counts the coins that precede the falling target coin. The coin to be dropped may be sandwiched between the two downstream stoppers 171 and the upstream stopper 176 to be separated from the preceding and succeeding coins based on the timing detected by 181. With this configuration, if the coin identified as the coin to be dropped by the identification sensor 165 is not detected at the timing that should be detected by the count sensor 181, it is determined that the coin is a small diameter coin and has fallen into the drop hole 115. It is possible to avoid operating the downstream stopper 171 and the upstream stopper 176 for this coin.

In the above, since the downstream stopper 171 is configured to operate independently by the stopper solenoid 172 and the upstream stopper 176 is operated independently by the stopper solenoid 177, the upstream stopper 176 is operated after the downstream stopper 171 is advanced. It becomes possible to select to move forward or to move forward at the same time, and it is possible to select the optimum method such as changing and controlling the amount of deviation in the timing of advance according to the outer diameter of the coin to be counted.

The upstream stopper 176 and the downstream stopper 171 may be moved forward in conjunction with each other. That is, if the upstream stopper 176 is positioned and shaped so that it can be inserted into the gap between the 1-yen coin, which is the minimum diameter coin, and the 500-yen coin, which is the maximum diameter coin, the upstream stopper 176 and the downstream stopper 171 are connected. Therefore, the number of parts can be reduced and the cost can be reduced as compared with the configuration in which the upstream stopper 176 and the downstream stopper 171 move forward and backward independently.

By advancing the upstream stopper 176 and the downstream stopper 171 to the coin moving range on the transport path 60, the coins to be dropped sandwiched between the upstream stopper 176 and the downstream stopper 171 are detected by the count sensor 181. When detected at the appropriate timing, this coin is a coin to be dropped with an outer diameter similar to that of a 100-yen coin. After the count sensor 181 detects the falling target coin, when the time required to release the 100-yen coin ahead of the falling target coin to the chute 19 elapses, the control unit 38 rotates forward. By temporarily stopping the motor 15 and the transfer motor 55, the rotating disk 14 and the feed belt 35 are temporarily stopped. After that, the rotary disk 14 and the feed belt 35 are reversed by reversing the feeding motor 15 and the transport motor 55 without changing the distance between the course guide walls 131 and 132, that is, the course width of the sorting course 133.

Then, by driving the feed belt 35 that reverses, the falling target coin having the same outer diameter as the 100-yen coin on the exit side passage portion 112 is conveyed toward the entrance side passage portion 61 side. At this time, the contact portion 178 of the upstream stopper 176 of the locus changing portion 179 is located on the fixed wall 73 side and closer to the movable wall 83 side than the end surface 105 of the support portion 101, and is conveyed by the reverse feed belt 35. The coin C to be dropped is abutted and pressed in the passage width direction so as to enter the passage width expanding portion 162 on the upper surface 104 of the support portion 103 as shown by the alternate long and short dash line in FIG. Then, the drop target coin C having an outer diameter similar to that of a 100-yen coin is located at a position where it overlaps the drop hole 115 in the extending direction of the passage, and the end portion on the support portion 101 side is a movable wall rather than the end surface 105 of the support portion 101. It will be located on the 83 side. As a result, the coin C to be dropped falls into the drop hole 115 without being supported by the support portion 101, and is discharged from the discharge port 25 into the exclusion box 26. Further, the coins on the entrance side passage portion 61 side of the falling target coin C, which have already been drawn out from the rotary disk 14 to the entrance side passage portion 61, are paired by the reversal of the feed belt 35 and the reversal of the rotary disk 14. While the outer peripheral surface is guided by the wall portions 63 and 64 of the above, the lower surface is supported and conveyed by the pair of support portions 101 and 103 and returned to the rotating disk 14.

Then, from the start of reversal of the feeding motor 15 and the conveyor motor 55, a coin to be dropped having an outer diameter similar to that of a 100-yen coin on the exit side passage portion 112 is dropped into the drop hole 115, and the coin is entered from the coin C to be dropped. When a predetermined time required for returning the coin on the side passage portion 61 side to the rotary disc 14 has elapsed, the control unit 38 temporarily stops the reversing feeding motor 15 and the conveyor 55 to temporarily stop the rotary disc 14 After stopping the feed belt 35, the stopper solenoids 172 and 177 are driven to raise the downstream stopper 171 and the upstream stopper 176 to return them to the standby position. After that, the feeding motor 15 and the transport motor 55 are rotated in the normal direction to rotate the rotary disk 14 and the feed belt 35 in the normal direction, the exclusion control is terminated, and the counting is restarted.

Further, the control unit 38 is a 500-yen coin in which the staying coin detection sensor 125 stays at the inlet 91 side of the pair of wall portions 63, 64 for a predetermined time or more while counting 100-yen coins accompanying the forward rotation drive of the feed belt 35. When a coin C having a diameter larger than that of a 100-yen coin such as a 10-yen coin is detected, the rotating disk 14 and the feed belt 35 are stopped by temporarily stopping the feeding motor 15 and the transport motor 55 that are rotating in the normal direction. Here, when the staying coin detection sensor 125 detects the coin C that stays for a predetermined time or longer, the rotation of the feed belt 35 is such that all the coins of the denomination to be counted on the transport path 60 are chute downstream of the transport path 60. It will be maintained until it is transported to 19, that is, until a predetermined time elapses in which the 100-yen coin that was transported before the staying coin does not remain on the transport path 60. When the distance of the transport path 60 is short as in the present embodiment, the drive of the feed belt 35 may be stopped immediately when the staying coin detection sensor 125 detects coins staying for a predetermined time or longer. ..

After that, the interval changing motor 120 is appropriately driven to appropriately drive the interval changing mechanism 121 to widen the interval between the course guide walls 131 and 132, that is, the course width of the sorting course 133 to the maximum width as shown in FIG. 5, and then maximize the course width. The forward rotation of the feed belt 35 is restarted by restarting the normal rotation of only the transfer motor 55 without driving the feeding motor 15 while maintaining a large amount. Then, by driving the feed belt 35 that rotates in the normal direction, the coin C whose stay is detected by the staying coin detection sensor 125 falls from the entrance side passage portion 61 into the drop hole 115 and is discharged from the discharge port 25 into the exclusion box 26. Will be. As a result, coins C having a diameter larger than that of the coin of the denomination to be counted can be automatically excluded. Further, some of the coins that have already been drawn out from the rotating disk 14 to the entrance side passage portion 61 also fall into the drop hole 115 due to the normal rotation of the feed belt 35, and are discharged from the discharge port 25 to the exclusion box 26. Will be. During this time, the rotating disk 14 is stopped and no coins are paid out.

Then, when a predetermined fixed time required for dropping the coin whose stay is detected by the staying coin detection sensor 125 into the drop hole 115 elapses from the restart of the normal rotation of the transport motor 55 (in other words, the feed belt 35 is fixed). After the feed belt 35 is stopped by temporarily stopping the transport motor 55 that is rotating in the normal direction), the interval changing motor 120 is appropriately driven by the interval changing mechanism 121, and the course guide wall 131, The distance between 132 is returned to the interval corresponding to the counting of 100-yen coins, which are coins of the denomination to be counted. Here, while the coins whose stay is detected by the staying coin detection sensor 125 are dropped into the drop hole 115, the rotating disk 14 is stopped and the coins are not drawn out. Therefore, between the course guide walls 131 and 132. Even if the distance is returned to the interval corresponding to the counting of 100-yen coins, coins including 10-yen coins and 500-yen coins having a diameter larger than that of 100-yen coins will not be caught between the walls 63 and 64. After that, the rotary disk 14 and the feed belt 35 are rotated in the normal direction by rotating the feeding motor 15 and the transport motor 55 in the normal direction, and the counting is restarted.

That is, when coin C larger than the outer diameter of the coin of the denomination to be counted is mixed in the hopper 12 and sent from the hopper 12 side to the transport path 60 side, the course width of the sorting course 133 of the transport path 60 is changed. Since it is narrower than the diameter of the coin C, it cannot enter the sorting course 133 and stays in the vicinity of the entrance 91 of the sorting course 133. When the control unit 38 detects the coin C accumulated on the inlet 91 side of the pair of wall portions 63, 64 while the feed belt 35 is being driven, the control unit 38 stops the feed belt 35 and then causes the interval changing mechanism 121. After increasing the distance between the course guide walls 131 and 132, and then driving the feed belt 35 in the direction of moving the coin at the entrance 91 toward the drop hole 115 for a certain period of time, the distance between the course guide walls 131 and 132 is increased. Return to the original position and restart the drive of the feed belt 35.

When the hopper sensor 16 detects that the rotating disk 14 has run out of coins during counting of 100-yen coins, it is necessary to release the last coin drawn from the rotating disk 14 from the chute 19 or the discharge port 25. When the time elapses, the control unit 38 stops the rotary disk 14 and the feed belt 35 by stopping the feeding motor 15 and the conveyor 55, and discharges the rotary disk 14 and the feed belt 35 to the chute 19 based on the identification counting result of the identification unit 165. The number of 100-yen coins is displayed on the operation display unit 30.

In the above, the case of counting 100 yen coins as the coins of the denomination to be counted has been described as an example, but other 1 yen coins, 5 yen coins, 10 yen coins, 50 yen coins, and 500 yen coins are counted respectively. The same applies to coins of the target denomination except that the denomination to be counted changes. When each of the 1-yen coin, 5-yen coin, 10-yen coin, 50-yen coin, and 500-yen coin is a coin of the denomination to be counted, the interval changing mechanism 121 provides between the course guide walls 131 and 132, that is, a pair of wall portions. The distance between 63 and 64 and the distance between the end faces 105 and 106 of the pair of support portions 101 and 103 are adjusted to the intervals corresponding to the counting of coins of the denomination to be counted.

The feeding motor 15 and the transport motor 55 are used as one motor, and the driving force from this one motor is transmitted to both the rotating disk 14 and the feed belt 35 by the clutch and to the rotating disk 14. It is also possible to switch to the state of transmitting only to the feed belt 35.

According to the first embodiment described above, when the coin is conveyed from the entrance side passage portion 61 to the exit side passage portion 112 by the feed belt 35 that rotates in the normal direction, the pair of wall portions 63, 64 and the pair of support portions 101 , 103 coins are moved toward the exit side passage portion 112 by being guided by a pair of wall portions 63 and 64 on the outer peripheral surface and being supported by a pair of support portions 101 and 103 on the outer peripheral side of the lower surface. Become. Further, coins having a diameter smaller than that of the coins supported by the pair of support portions 101 and 103 fall from the drop hole 115 between the pair of support portions 101 and 103 and are eliminated. Here, if there is a coin identified as a fall target coin by the identification sensor 165 among the coins conveyed to the exit side passage portion 112, this coin C is conveyed to the entrance side passage portion 61 side by the reversing feed belt 35. Then, in the locus changing portion 179, the passage width provided on the exit side passage portion 112 side of one wall portion 64 is wider than the wall constituent portion 161 on the entrance side passage portion 61 side to increase the distance from the other wall portion 63. It is moved to the enlargement portion 162 side and dropped into the drop hole 115. Therefore, it is not necessary to perform an operation of widening or returning the distance between the pair of wall portions 63, 64 and the pair of support portions 101, 103, so that the pair of wall portions 63, 64 and the pair of support portions 101, 103 are operated. There is no need for time to make the coins, and the target coins can be automatically eliminated in a short time. As a result, it is possible to accelerate the resumption of the sorting and counting operation for the remaining coins returned on the rotating disk 14.

Further, the control unit 38 is between a coin conveyed to the exit side passage portion 112 and identified as a coin to be dropped by the identification sensor 165 and a subsequent coin adjacent to the entrance side passage portion 61 side of this coin. Since the upstream stopper 176 of the locus change portion 179 is advanced, it is possible to suppress unnecessary dropping of the subsequent coins on the entrance side passage portion 61 side of the coin identified as the coin to be dropped into the drop hole 115. ..

<Second Embodiment>
The coin processing apparatus of the second embodiment according to the present invention will be described mainly with reference to FIGS. 6 and 7, focusing on differences from the first embodiment.

As shown in FIG. 6, in the coin processing apparatus of the second embodiment, the drop hole 115 is a partition portion 201 arranged at an intermediate position in the passage extending direction, and is an inlet side drop hole portion on the entrance side passage portion 61 side. It is divided into 202 and the exit side drop hole portion 203 on the outlet side passage portion 112 side.

The outlet-side drop hole 203 is communicated with the discharge port 25 shown in FIG. 7 by a chute (not shown), and the inlet-side drop hole 202 is a chute (not shown) different from the outlet-side drop hole 203 in FIG. It communicates with the second outlet 205 shown. That is, the discharge port 25 discharges only the coins that have fallen into the outlet side drop hole 203, and the second discharge port 205 discharges only the coins that have fallen into the inlet side drop hole 202.

The second discharge port 205 is provided on the side portion of the main body portion 18 so as to be aligned in the front-rear direction with respect to the discharge port 25. On the side of the main body 18, second exclusion boxes 206 having an upper opening for receiving coins released from the second discharge port 205 are provided side by side in the front-rear direction with respect to the exclusion box 26 at the same height. There is. That is, the inlet side drop hole portion 202 removes coins into the second exclusion box 206, and the exit side drop hole portion 203 removes coins into the exclusion box 26 at a different position.

The inlet-side drop hole portion 202 drops an unsupportable small-diameter coin between the pair of support portions 101 and 103, which is conveyed from the inlet-side passage portion 61 by the feed belt 35 that rotates in the normal direction. The outlet-side drop hole portion 203 is conveyed from the exit-side passage portion 112 by the reversing feed belt 35, and the locus changing portion 179 drops the coin shifted to the passage width expansion portion 162 side. The length of the drop hole 115, the position of the partition portion 201 with respect to the drop hole 115, the position and shape of the upstream stopper 176 with respect to the drop hole 115, and the passage width expansion portion 162 with respect to the drop hole 115 so as to drop the coin in this way. The position, shape, etc. are set.

According to the second embodiment described above, a small-diameter coin that cannot be supported between the pair of support portions 101 and 103, which is conveyed from the entrance side passage portion 61 by the feed belt 35 that rotates in the normal direction, is inserted into the inlet side drop hole portion. It will be dropped to 202. On the other hand, a coin conveyed from the exit side passage portion 112 by the reversing feed belt 35 and shifted to the passage width expansion portion 162 side by the trajectory changing portion 179 is dropped into the outlet side drop hole portion 203 to form a small diameter coin. Will be excluded in another position. Therefore, after elimination, the work of separating the small-diameter coin and the identification abnormal coin becomes unnecessary.

<Third Embodiment>
The coin processing apparatus of the third embodiment according to the present invention will be described mainly with reference to FIG. 8 and focusing on differences from the first embodiment.

As shown in FIG. 8, the passage width expanding portion 162 of the third embodiment is movable with the passage width expanding main body portion 221 formed in the movable wall 83 so as to be recessed in the passage width direction from the wall surface 151 of the wall constituent portion 161. A support shaft 222 provided at a fixed position with respect to the wall 83, a regulating portion 223 rotatably provided around the support shaft 222, and a regulating portion 223 provided at a fixed position with respect to the movable wall 83 and abutting against the regulating portion 223. A predetermined amount in the direction of separating the stopper portion 224, the spring 225 that urges the regulating portion 223 to abut against the stopper portion 224, and the restricting portion 223 electrically against the urging force of the spring 225 from the stopper portion 224. It has a solenoid 226 to rotate.

As shown in FIG. 8 (a), the regulating portion 223 has a basic position where the solenoid 226 is in the off state and is brought into contact with the stopper portion 224 by the urging force of the spring 225. As shown, when the solenoid 226 is turned on, it is driven by the solenoid 226 and the rotation position is a position separated from the stopper portion 224 by a predetermined amount.

When the restricting portion 223 is in the basic position as shown in FIG. 8A, the regulating portion 223 is flush with the wall surface 151 of the wall constituent portion 161 on the exit side passage portion 112 side in the passage extending direction with respect to the wall constituent portion 161. When the wall surface 231 is provided on the drop hole 115 side in the passage width direction and is in the rotational position as shown in FIG. 8 (b), the wall surface 231 is the wall surface 152 of the first embodiment (see FIG. 4). Will be tilted in the same way as. That is, the passage width expanding portion 162 of the third embodiment sets the distance between the drop hole 115 and the wall portion 63 (not shown in FIG. 8, see FIG. 4) at a position where the drop hole 115 overlaps in the passage extending direction. It is possible to switch between a basic state equivalent to 161 and a rotating state wider than the wall component 161. Further, the passage width expanding portion 162 of the third embodiment is electrically driven and controlled directly (that is, without using coins), and the wall portion 63 at a position where it overlaps the drop hole 115 in the passage extending direction (FIG. FIG. In No. 8, the distance from the wall component (not shown. See FIG. 4) can be switched between a state in which the distance is equal to that of the wall component 161 and a state in which the distance is wider than the wall component 161.

Explaining with reference to FIG. 4, the above-mentioned exclusion control is performed on the coins that are not identified as the counting target denomination by the identification sensor 165 during the counting of coins, that is, the coins to be dropped into the drop hole 115. Based on the timing when this is detected by the identification sensor 165, the downstream stopper 171 that has been in the standby state until then is lowered to advance the contact portion 173 within the coin movement range on the transport path 60. The upstream stopper 176, which had been in the standby state until then, is lowered to advance the contact portion 178 within the coin movement range on the transport path 60.

Then, the downstream stopper 171 has a contact portion 173 between the coin to be dropped and the coin of the denomination to be counted adjacent to the side opposite to the entrance side passage portion 61 of the coin to be dropped, and the coin to be dropped. In the upstream stopper 176, the contact portion 178 is inserted between the falling target coin and the subsequent coins adjacent to the inlet side passage portion 61 side of the falling target coin. At this time, since the subsequent coins come into contact with the coins to be dropped and their movement to the downstream side is restricted, in the configuration of the first and second embodiments, they move to the passage width expanding portion 162 side in the passage width direction. there is a possibility.

On the other hand, in the passage width expansion portion 162 of the third embodiment, as shown in FIG. 8A, the regulation portion 223 is at the basic position, and the wall surface 231 on the drop hole 115 side is the wall constituent portion 161. The exit side passage portion 112 side of the wall surface 151 is flush with the wall surface 151, and this state is maintained by the urging force of the spring 225. Therefore, the subsequent coins described above are more than the wall surface 151 of the wall constituent portion 161. The regulation unit 223 regulates the movement to the side opposite to the drop hole 115 in the passage width direction. In other words, the regulation unit 223 at the basic position restricts the movement of the following coins from the wall surface 151 of the wall component 161 to the side opposite to the drop hole 115. As a result, it is possible to prevent the subsequent coins from moving toward the movable wall 83 side of the end face 105 of the support portion 101 (not shown in FIG. 8; see FIG. 4) and accidentally falling into the drop hole 115. ..

After the downstream stopper 171 and the upstream stopper 176 are lowered, the control unit 38 rotates the rotating disk in the normal direction when a predetermined time required to release the coins ahead of the falling target coin from the chute 19 elapses. 14 and the feed belt 35 are reversed. In parallel with this, the control unit 38 drives the solenoid 226 to position the regulation unit 223 at the rotation position as shown in FIG. 8 (b). Then, by driving the feed belt 35 that reverses, the subsequent coins described above are conveyed with the lower surface supported by the pair of support portions 101 and 103, and the wall surface 72 of the fixed wall 73 and the wall constituent portion 161 of the movable wall 83. While the outer peripheral surface is guided by the wall surface 151, the outer peripheral surface is returned to the rotating disk 14 via the entrance side passage portion 61. At the same time, the coin to be dropped is conveyed toward the entrance side passage portion 61 side by the drive of the reverse feed belt 35, and as in the first embodiment, the hit of the upstream side stopper 176 of the trajectory changing portion 179. At a position where it abuts on the contact portion 178 and overlaps the drop hole 115 in the passage extending direction, the movement locus is shifted in the passage width direction so as to enter the passage width expanding portion 162 at the rotating position, and the drop hole 115 Will be discharged from the discharge port 25 to the exclusion box 26.

Then, when a predetermined time required for dropping the coin to be dropped into the drop hole 115 and returning the coin on the entrance side passage portion 61 side of the fall target coin C to the rotating disk 14 elapses, the control unit 38 rotates. The disk 14 and the feed belt 35 are stopped, and the downstream stopper 171 and the upstream stopper 176 are raised to return to the standby position. After that, the rotating disk 14 and the feed belt 35 are rotated in the normal direction to end the exclusion control and restart the counting.

The passage width expanding portion 162 of the third embodiment has a state in which the distance between the drop hole 115 and the wall portion 63 at a position overlapping in the passage extending direction is equal to that of the wall constituent portion 161 and is larger than that of the wall constituent portion 161. Since it is possible to switch to the expanded state, the distance between the drop hole 115 and the wall portion 63 at the position where it overlaps in the passage extending direction is made equal to that of the wall constituent portion 161 so that the entrance side passage portion 61 to the exit side passage It is possible to prevent coins that are conveyed toward the portion 112 and that match the distance between the pair of wall portions 63, 64 and the pair of support portions 101, 103 from accidentally entering and falling into the drop hole 115. Further, the passage width expanding portion 162 has a drop hole from the exit side passage portion 112 by making the distance between the drop hole 115 and the wall portion 63 at a position overlapping in the passage extending direction wider than that of the wall component portion 161. A coin can be dropped on the 115.

Further, in the passage width expanding portion 162 of the third embodiment, the on / off of the drive is directly controlled by electric power, and the distance between the drop hole 115 and the wall portion 63 at a position overlapping in the passage extending direction is set as a wall configuration. Since it is possible to switch between a state of being equivalent to the portion 161 and a state of being wider than the wall constituent portion 161, the switching can be smoothly performed.

<Fourth Embodiment>
The coin processing apparatus of the fourth embodiment according to the present invention will be described mainly with reference to FIG. 9, focusing on the differences from the first embodiment.
