  As shown in FIG. 8, the holding plate 87 extends vertically on the lateral sides of the cassettes 50 that are arranged in a multi-stage above and below, and extends to the respective cassettes 50 on the holding plate 87. 9 is attached with a bar metal holding mechanism 80 shown in FIG.

  The bar metal holding mechanism 80 is fixed to the holding plate 87 so as to extend toward the cassette 50, and forms a carrier 91 with the holding plate 87. The carrier main body 95 includes a carrier main body (support portion) 95. A receiving block (first member) 96 connected so as to extend rearward from the receiving block 96, and a holding block (second member) 97 connected to the receiving block 96 so as to extend rearward from the receiving block 96; have. Since the carrier main body 95 of all the bar metal holding mechanisms 80 is fixed to the holding plate 87, the carrier 91 composed of the holding plate 87 and the plurality of carrier main bodies 95 moves along the length direction of the cassette 50. It is provided as possible.

  The carrier body 95 is provided with a rotating shaft 100 along the width direction of the cassette 50, and the receiving block 96 is supported by the rotating shaft 100 so that the base end side thereof can rotate. The receiving block 96 extends in the left-right direction so as to connect the pair of left and right extending portions 101 shown in FIGS. 10 and 11 extending rearward from the rotation shaft 100 and the rear ends of these extending portions 101. And a distal end connecting portion 102. The tip connecting portion 102 is formed so as to protrude below the extending portion 101.

  Here, the swinging range of the receiving block 96 is restricted by a stopper (not shown) so that the receiving block 96 swings up and down within a predetermined angle range while maintaining the posture of extending backward. When the receiving block 96 is in the one-side lowered state that is lowered to the lowest side, the front end connecting portion 102 is placed on the front side that is one side of the front and back of the bar B on the bottom surface 70a of the cassette 50, as shown in FIG. In addition, it is arranged at a height that restricts the passage of the bar B. Further, when the receiving block 96 is in the one-side raised state where it has been raised to the uppermost side, as shown in FIG. 15, the tip connecting portion 102 is a height that allows passage of the bar B on the bottom surface 70 a of the cassette 50. Place it.

  Although not shown between the receiving block 96 and the carrier main body 95, the receiving block 96 swings below the carrier main body 95 from an intermediate predetermined biasing direction switching position (intermediate predetermined position). When it is moved, it is biased downward and maintained in the one-side lowered state, while when the receiving block 96 swings upward from the biasing direction switching position, it is biased upward to raise one side. An unillustrated receiving block biasing spring (biasing member) is provided to maintain the same. That is, the receiving block urging spring causes the receiving block 96 to perform a so-called snap action on the carrier body 95 up and down.

  As shown in FIGS. 10 and 11, a rotation shaft 105 is provided along the width direction of the cassette 50 on the front end side of the extending portion 101 of the receiving block 96. The base end side is rotatably supported by the shaft 105. The holding block 97 extends in the left-right direction so as to connect the pair of left and right extending portions 106 extending further rearward than the receiving block 96 from the rotating shaft 105 and the rear end portions of these extending portions 106. And a leading end connecting portion 107. The distal end connecting portion 107 side and the distal end connecting portion 107 of the extending portion 106 are formed in a curved shape that protrudes below the opposite side of the extending portion 106 from the distal end connecting portion 107.

  Here, the rocking range of the holding block 97 is restricted by a stopper (not shown) so as to rock vertically within a predetermined angle range with a posture extending rearward with respect to the receiving block 96. When the holding block 97 is in the other side lowered state with respect to the receiving block 96 in the one side lowered state, the tip connecting portion 107 is connected to the bar metal on the bottom surface 70a of the cassette 50 as shown in FIG. It arrange | positions to the rear side which is the other side before and after B in the height which controls passage of bar metal B. Further, when the holding block 97 is in the other side raised state that is raised with respect to the receiving block 96 that is in the one side lowered state, the tip connecting portion 107 is on the bottom surface 70a of the cassette 50 as shown in FIG. It arrange | positions at the height which accept | permits the passage of the bar B.

  Further, as shown in FIGS. 15 and 16, when the receiving block 96 is in the one-side raised state, the pressing block 97 can be attached to the cassette 50 even if it is in the most lowered state with respect to the receiving block 96. It arrange | positions at the height which accept | permits the passage of the bar B on the bottom surface 70a.

  As shown in FIG. 11, the carrier body 95 is provided with two rotating shafts 110 and 111 on the front and rear sides. An arm 112 is fixed to the receiving block 96 side of the rotating shaft 110 on the front side so as to extend rearward, and the front end side of the arm 112 protrudes toward the receiving block 96 and is provided on the side of the receiving block 96. An engagement pin 114 that engages with the engagement groove 113 is fixed. Further, an arm 115 is fixed so as to extend rearward on the opposite side of the front rotating shaft 110 from the receiving block 96, and the arm 115 protrudes to the opposite side of the receiving block 96 on the tip side. An operating pin 116 is fixed. As the operating pin 116 moves up and down, the arm 115, the rotating shaft 110, and the arm 112 provided integrally therewith rotate, and the engaging pin 114 fixed to the arm 112 moves up and down to move the receiving block 96. Move up and down.

  In addition, an arm 120 is fixed to the holding block 97 side of the rear rotating shaft 111 so as to extend rearward. An engagement pin 122 that engages with the engagement groove 121 is fixed. Also, an arm 123 is fixed so as to extend rearward on the opposite side of the rear rotating shaft 111 from the pressing block 97, and the arm 123 protrudes on the opposite side to the pressing block 97 on the tip side. An operating pin 124 is fixed. As the operating pin 124 moves up and down, the arm 123, the rotating shaft 111 and the arm 120 provided integrally with the operating pin 124 rotate, and the engaging pin 122 fixed to the arm 120 moves up and down to move the holding block 97. Move up and down.

  As shown in FIG. 12, the bar holding mechanism 80 stops at a predetermined receiving position on the rear end side of the cassette 50 and receives the bar B from the storage distribution unit 51. When the bar holding mechanism 80 is moved to the rear end side, the operating pin 116 is lowered at a predetermined position before the receiving position by using the moving force to be in the one side raised state as will be described later. A rearward-lowering descending conversion member 130 is fixed, which swings the receiving block 96 below the biasing direction switching position. The descending conversion member 130 causes the receiving block 96 to be lowered to one side at a predetermined receiving position.

  Further, the cassette 50 has a receiving position with respect to the receiving block 96 that is lowered to one side by the lowering conversion member 130 and a receiving block biasing spring (not shown) when moving to the rear end side of the bar holding mechanism 80. As shown in FIG. 12, the operating pin 124 is lifted by using this moving force at a predetermined position in front, and the holding block 97 that has been lowered to the other side is swung upward as will be described later. A retreat conversion member 131 having a rearward rising shape that is in a state of rising on the other side is fixed. Note that the retracting conversion member 131 has a front-up shape, a middle portion parallel to the bottom surface 70a of the cassette 50, and a rear portion having a back-down shape, and the bar holding mechanism 80 is in the receiving position. Sometimes the operating pin 124 is located on the middle part.

  As described above, when the bar holding mechanism 80 is in the receiving position shown in FIGS. 12 and 13, the receiving block 96 is lowered to the lower side with respect to the carrier body 95 to receive the holding block 97. The other side is lifted up by swinging upward with respect to the block 96. In this state, when the bar B is discharged from the storage distribution part 51 onto the bottom surface 70a of the rear end portion of the cassette 50 in a posture along the width direction of the cassette 50, the bar B is moved forward by the inclination of the bottom surface 70a. , And contact the receiving block 96 through the lower side of the pressing block 97 and stop in a posture along the width direction of the cassette 50 (state shown in FIG. 13). The bar holding mechanism 80 stops at this receiving position when it is in a standby state. Further, a receiving position sensor (not shown) for detecting from the position of the holding plate 87 that the bar holding mechanism 80 is located at the receiving position is provided.

  Then, when the bar holding mechanism 80 moves to the front end side of the cassette 50 from the state in which the bar B is received in this way, at the initial stage, as shown in FIG. As a result, the presser block 97 descends and comes into contact with the bar B. As a result, the bar holding mechanism 80 is in a state where the receiving block 96 is lowered to the one side and the holding block 97 is lowered to the other side, and is lowered, and the bar B on the bottom surface 70a of the cassette 50 is moved upward. It will be in the state to hold as it holds. In other words, the bar metal holding mechanism 80 holds the bar B from the upper side, and in other words, the bar metal holding mechanism 80 holds the bar B integrally from the upper side so as not to move relative to each other. It becomes. At this time, the bar B is in a three-point support state as viewed in the axial direction in which the front side is in contact with the receiving block 96, the rear side is in contact with the holding block 97, and the lower side is in contact with the bottom surface 70a. When the 80 cassette 50 is moved to the front end side, the cassette 50 is moved to the front end side in the three-point supported state. In other words, the bar metal B is moved by the bar metal holding mechanism 80 in a posture along the width direction of the cassette 50 without being staggered, skewed, or delayed with respect to the bar metal holding mechanism 80.

  Here, the receiving block 96 of the bar metal holding mechanism 80 comes into contact with the bar B already stored in the cassette 50 when the bar metal holding mechanism 80 moves to the front end side of the cassette 50, and is in a one side lowered state. A contact portion 133 that swings the receiving block 96 located above the biasing direction switching position is formed in the lower portion of the distal end connecting portion 102 on the rotating shaft 100 side.

  That is, when the bar holding mechanism 80 moves to the front end side of the cassette 50 while holding the bar B with the receiving block 96 in the lowering state on one side and the holding block 97 in the lowering state on the other side as described above, the holding is held. After the bar B is in contact with the rearmost one of the bar B already stored in the cassette 50, the contact portion 133 of the receiving block 96 is the end of the bar B already stored in the cassette 50. It abuts on the object and rides on the bar B using the moving force. As a result, the receiving block 96 is swung to the upper side of the urging direction switching position, and as shown in FIG. 15, the urging force of the receiving block urging spring is raised to one side. As a result, both the receiving block 96 and the pressing block 97 are separated from the bar B, and the receiving and pressing of the bar B are released. At this time, before the contact portion 133 contacts the last bar B, the bar B held by the receiving block 96 and the holding block 97 comes into contact with the last bar B and stops. However, the holding block 97 on the rear side is swung upward by the metal bar B that is held, and moves to the front of the metal bar B. Note that when the bar holding mechanism 80 is located at the receiving position, the receiving block 96 and the holding block 97 do not come into contact with the last one of the bar B already stored in the cassette 50. The storage space (full capacity) of the bar B is set. That is, the rear end portion of the storage space for storing the bar B of the cassette 50 is set in front of the receiving position.

  Further, when the bar 50 is moved to the front end side of the cassette 50, this movement is performed immediately before the bar B held by the bar holding mechanism 80 comes into contact with the front end plate portion 72 of the cassette 50. A lifting conversion member 135 shown in FIG. 16 having a front rising shape is fixed by using the force to raise the operating pin 116 and swing the receiving block 96 that has been lowered to one side above the biasing direction switching position. Has been.

  That is, when the bar holding mechanism 80 moves to the front end side of the cassette 50 while holding the bar B with the receiving block 96 in the lowering state on one side and the holding block 97 in the lowering side on the other side, the bar 50 is already stored in the cassette 50. In a state where there is no bar B, the ascending conversion member 135 lifts the operating pin 116 using the moving force of the bar holding mechanism 80 immediately before the held bar B contacts the front end plate portion 72. As a result, the receiving block 96 swings upward from the biasing direction switching position and is raised to one side by the biasing force of the receiving block biasing spring. As a result, the receiving block 96 and the pressing block 97 are both separated from the bar B, and the receiving and pressing of the bar B are released. Then, the bar B held by the bar holding mechanism 80 comes into contact with the front end plate 72 of the cassette 50 and stops. The bar holding mechanism 80 temporarily stops at the front end position after the operating pin 116 is lifted by the lift conversion member 135 and returns to the standby position on the rear end side. A front end position sensor (not shown) that detects the position at the front end position from the position of the holding plate 87 is provided.

  As shown in FIG. 7, the carrier main body 95 provided on the upper side of each cassette 50 has a magnetic body on the lower side and the upper side as shown in FIG. 9, except for the upper carrier main body 95 of the uppermost cassette 50. Sensors 140 and 141 are attached. The lower magnetic sensor 140 supported by the carrier body 95 scans the bar B stored in the cassette 50 immediately below and detects the magnetic data. The upper magnetic sensor 141 supported by the same carrier body 95 scans the bar B stored in the upper cassette 50 and passes the magnetic data through a detection groove (not shown) formed in the bottom plate portion 70. To detect. That is, among the carriers 91, the carrier main body 95 excluding the upper carrier main body 95 of the uppermost cassette 50 is located between the upper and lower adjacent cassettes 50 and serves as a common support for these cassettes 50, and is adjacent to the upper and lower cassettes. One of the pair of magnetic sensors 140 and 141 for the bar B stored in the upper one of the matching cassettes 50 and the other lower side of the adjacent cassettes 50. The magnetic sensor 141 which is one of the upper side of the pair of magnetic sensors 140 and 141 for the metal bar B housed in the object is supported.

  Here, the lower magnetic sensor 140 of the carrier main body 95 provided immediately above the cassette 50 and the upper magnetic sensor 141 of the carrier main body 95 provided immediately below the same cassette 50 are mutually connected to the carrier main body 95. Are arranged in a direction perpendicular to the bottom surface 70a of the cassette 50 between them, and detects magnetic data of the bar B stored in the cassette 50. A magnetic data detection unit (magnetic data detection means) 142 is configured. That is, the magnetic data detection unit 142 includes a pair of magnetic sensors 140 and 141 arranged so as to sandwich the bar B stored in the cassette 50 in the diameter direction.

  Note that only the lower magnetic sensor 140 is attached to the upper carrier body 95 of the uppermost cassette 50 and is opposed to the upper magnetic sensor 141 of the upper carrier body 95 of the second cassette 50 from the top. Thus, the magnetic data detection unit 142 that detects the bar B stored in the uppermost cassette 50 is configured.

  A lower carrier body 95A that constitutes the carrier 91 and only supports the magnetic sensor 141 extends from the holding plate 87 below the lowermost cassette 50. The lower carrier body 95A includes A magnetic sensor 140 is attached upward. The magnetic sensor 140 is opposed to the lower magnetic sensor 141 on the upper carrier body 95 of the lowermost cassette 50, and detects a bar B accommodated in the lowermost cassette 50. Configure.

  All the cassettes 50 have a receiving position for receiving the bar B from the storage sorting unit 51 by the bar holding mechanism 80 from the receiving position at the rear end that receives the bar B discharged from the storage sorting unit 51. As shown in FIG. 17, a receiving table portion 54 that is substantially parallel to the bottom surface 70 a of the cassette 50 and that is one step higher than the bottom surface 70 a is formed to the rear. A hole portion 146 shown in FIGS. 18 and 19 is formed in the receiving base portion 54 so as to penetrate vertically from the receiving position to the front side. The reference magnetism can protrude from the hole portion 146 onto the receiving base portion 54. A member 150 is provided.

A rotating shaft 151 is rotatably provided at a fixed position along the width direction of the cassette 50 on the lower side of the receiving table 54, and the reference magnetic member 150 is fixed to the rotating shaft 151.
As shown in FIG. 17, the reference magnetic member 150 connects a pair of arcuate portions 152 that are concentrically arranged at positions different by 180 degrees and intermediate portions of the arcuate portions 152 in the circumferential direction. And a connecting plate portion 153. The reference magnetic member 150 is fixed to the rotating shaft 151 in one arcuate portion 152, and the center axis of the arcuate portions 152 on both sides is parallel to the rotating shaft 151.

  The reference magnetic member 150 is formed of the same material as the denomination of the bar metal B to be stored in the cassette 50 in which the reference magnetic member 150 is provided, and the outer diameter of the arcuate portion 152 is stored in the cassette 50. It has the same outer diameter as the B coin. That is, the reference magnetic member 150 provided in the cassette 50 for storing the 1-yen coin bar B is formed of the same material and the same diameter as the 1-yen coin. Similarly, the reference magnetic member 150 of the 5-yen bar cassette 50 has the same material and diameter as the 5-yen coin, and the reference magnetic member 150 of the 10-yen bar cassette 50 has the same material as the 10-yen coin. The reference magnetic member 150 of the 50-yen bar cassette 50 has the same diameter and the same material as the 50-yen coin, and the reference magnetic member 150 of the 100-yen bar cassette 50 has the same diameter as the 100-yen coin. The reference magnetic member 150 of the cassette 50 for a 500 yen bar is made of the same material and the same diameter as the 500 yen coin.

  Here, the reference magnetic member 150 is provided between the receiving position and the receiving position. Further, the reference magnetic member 150 has the same height from the bottom surface 70a to the center of the bar B on the bottom surface 70a of the cassette 50.

  As shown in FIGS. 18 and 20, the reference magnetic member 150 is retracted downward from the receiving base 54 of the cassette 50 as shown in FIGS. 18 and 20, or the receiving base of the cassette 50 is shown in FIGS. Or protrude from the portion 54 into the cassette 50. That is, as shown in FIGS. 17, 19, and 21, the detection state in which the direction connecting the pair of arcuate portions 152 intersects the receiving base 54 and protrudes from the receiving base 54, and FIGS. 18 and 20 As shown, the direction connecting the pair of arcuate portions 152 can be switched to a retracted state in which the direction is parallel to the receiving table 54 and retracts from the receiving table 54. The reference magnetic member 150 is urged by a reference magnetic member urging spring (not shown) so as to be maintained in the retracted state. An arm member 156 is fixed to the rotation shaft 151 along the radial direction. The arm member 156 has a roller 157 that is rotatable on the opposite side of the rotation shaft 151 in parallel with the rotation shaft 151.

Here, as shown in FIG. 17, the position where the reference magnetic member 150 in the detection state is sandwiched in the diameter direction is detected by the pair of magnetic sensors 140 and 141 of the magnetic data detection unit 142. The carrier 91 can place the magnetic data detection unit 142 at this adjustment position where the reference magnetic member 150 is provided.
This adjustment position is provided between the receiving position and the receiving position, that is, between the receiving position and the storage space for storing the bar B. An adjustment position sensor (not shown) that detects from the position of the holding plate 87 that the magnetic data detection unit 142 of the bar metal holding mechanism 80 is located at the adjustment position is provided.

  As shown in FIG. 20, when the reference magnetic member 150 is in the retracted state, the arm member 156 protrudes rearwardly, and the receiving position is set so that the carrier body 95 positions the magnetic data detection unit 142 at the adjustment position. When it moves past and beyond, the operation inclined surface 160 formed on a part of the holding plate 87 abuts on the roller 157 of the arm member 156, and the arm member 156 is swung by the moving force so as to be integrated with the arm member 156. The provided reference magnetic member 150 is rotated from the retracted state. When the carrier 91 places the magnetic data detection unit 142 at the adjustment position and stops, the reference magnetic member 150 enters a detection state as shown in FIGS. 17, 19, and 21. On the contrary, when the carrier 91 moves from this state to, for example, the receiving position, a part of the operation inclined surface 160 of the holding plate 87 releases the contact of the arm member 156 with the roller 157 and the reference magnetic member biasing spring is applied. The arm member 156 is swung by the force to return the reference magnetic member 150 to the retracted state shown in FIGS. Note that the receiving block 96 and the holding block 97 of the bar holding mechanism 80 are moved rearward from the receiving position, and immediately after the magnetic data detection unit 142 is positioned at the adjustment position, the cassette 50 is positioned behind the reference magnetic member 150. The receiving block 96 and the holding block 97 are positioned on the end side, and are set so as not to interfere with the protruding reference magnetic member 150.

  A buffer member 161 that protrudes slightly above the receiving base 54 is provided in the hole 146 of the receiving base 54. The buffer member 161 is biased upward by a spring, and alleviates the collision of the bar B released from the storage distribution part 51 to the receiving position with the receiving base part 54.

  In the bar metal storage device 10 having the above configuration, for example, when the bar B created by the packaging unit 36 is stored in the cassette 50 of the corresponding denomination, the control unit 31 is transported up by the pusher 51a of the storage distribution unit 51. The bar B is pushed out from the portion 48 and discharged to the receiving position at the rear end of the corresponding cassette 50. Then, the bar B moves the receiving base part 54 with the reference magnetic member 150 in the retracted state forward due to its inclination, falls to the bottom surface 70a of the cassette 50 that is one step lower than the receiving base part 54, and further moves forward. . At this time, as shown in FIG. 12, the bar holding mechanism 80 waiting at the receiving position is in a one-side lowered state in which the receiving block 96 is swung downward with respect to the carrier body 95, and the holding block 97 is moved. Since the other side of the receiving block 96 is swung upward with respect to the receiving block 96, the bar B passes through the lower side of the holding block 97 and contacts the tip connecting portion 102 of the receiving block 96 as shown in FIG. 13. It stops in a posture along the width direction of the contact cassette 50.

  After the pusher 51a of the storage distribution unit 51 is operated as described above, the control is performed at a timing after the elapse of time when it is assumed that the bar B comes into contact with the receiving block 96 of the bar holding mechanism 80 at the receiving position. The unit 31 drives the motor 90 to move the holding plate 87 forward. Then, the bar holding mechanism 80 moves toward the front end side of the cassette 50, and at the initial stage, the operating pin 124 descends along the retracting conversion member 131, and the pressing block 97 descends by its own weight as shown in FIG. Then, it contacts the bar B. As a result, the receiving block 96 and the holding block 97 of the bar holding mechanism 80 hold the bar B received from the upper side so that the bar B is moved forward, and the bar B is conveyed forward.

  When there is a bar B already stored in the cassette 50, the bar holding mechanism 80 that moves forward is the last of the bars B that are already stored in the cassette 50. After coming into contact with the tail, the contact part 133 of the receiving block 96 comes into contact with the last part of the bar B already stored in the cassette 50, and is swung upward as shown in FIG. As a result, the receiving block 96 is raised to one side by the urging force of the receiving block urging spring, and both the receiving block 96 and the holding block 97 escape upward from the bar B, and the bar B is received and pressed. Is released.

  Further, when there is no bar B already stored in the cassette 50, the bar holding mechanism 80 that moves forward is immediately before the bar B that is held contacts the front end plate portion 72 of the cassette 50. As shown in FIG. 16, the operating pin 116 is lifted by the rising conversion member 135, the receiving block 96 is swung upward, and the receiving block urging spring is biased to one side, and the receiving block is moved upward. Both 96 and the holding block 97 escape upward from the bar B, and the receiving and pressing of the bar B are released. Then, the bar B held by the bar holding mechanism 80 comes into contact with the front end plate 72 of the cassette 50 and stops.

  When the holding plate 87 is detected by the front end position sensor, the control unit 31 determines that the bar holding mechanism 80 has reached the front end position, and stops and reverses the motor 90. Then, the holding plate 87 moves rearward, and the bar metal holding mechanism 80 also releases the receiving block 96 and the holding block 97 upward from the bar B of the cassette 50 while keeping the receiving block 96 in the one side upward state. Move backwards in the same state.

  Then, as shown in FIG. 12, the bar holding mechanism 80 that moves rearward is moved down by the lower conversion member 130 at a predetermined position before the receiving position, and the one side ascending state. The receiving block 96 is swung downward, and is lowered to one side by the urging force of the receiving block urging spring. At this time, in the bar holding mechanism 80, the operating pin 124 is lifted by the retracting conversion member 131, and the pressing block 97 is swung upward to enter the other side lifted state.

  When the holding plate 87 is detected by a receiving position sensor (not shown), the control unit 31 determines that the bar holding mechanism 80 has reached the receiving position, and stops the motor 90.

  As described above, the bar metal B is stored one by one by the bar metal holding mechanism 80 in one cassette 50. In addition, since only one bar B is stored in the same holding plate 87, all the bar holding mechanisms 80 operate in the same manner. A bar holding mechanism 80 holds the bar B and conveys it.

  Further, when a height confirmation operation for confirming the height of normal bars for all cassettes 50 is input via the operation unit 30, the height confirmation is performed by the confirmation means 31a (see FIG. 2) of the control unit 31. The processing is started, and correction value calculation processing (calibration) is first performed from a standby state in which all the bar holding mechanisms 80 are in the receiving position.

That is, first, the motor 90 is driven to move the holding plate 87 backward. Then, the holding plate 87 brings the operating inclined surface 160 into contact with the rollers 157 of the arm members 156 connected to all the reference magnetic members 150 as shown in FIG. And the reference magnetic member 150 provided integrally with the arm member 156 is rotated from the retracted state. Then, when the holding plate 87 is detected by the adjustment position sensor, the control unit 31 stops the motor 90, whereby the operation inclined surface 160 provided on the holding plate 87 is as shown in FIG. All the reference magnetic members 150 are set in the detection state.
At this time, as shown in FIG. 17, the reference magnetic member 150 is disposed between the pair of magnetic sensors 140 and 141 facing all the magnetic data detection units 142.

  In this state, the control unit 31 detects the magnetic data (reference magnetic data) of the reference magnetic member 150 by all the magnetic data detection units 142. Here, the reference temperature data obtained by detecting the reference magnetic member 150 at the adjustment position when all the magnetic data detection units 142 are at the reference temperature is stored in the storage unit (not shown) for each magnetic data detection unit 142. This reference temperature data is compared with the detection data obtained by detecting the reference magnetic member 150 this time, and the amount of data shift (sensitivity change) due to temperature change is determined for each magnetic data detection unit 142. The calculated value is stored as a correction value in the storage unit for each magnetic data detection unit 142. This completes the correction value calculation process.

  Immediately after the correction value calculation process, the confirmation unit 31a of the control unit 31 performs a head height confirmation process. That is, first, the motor 90 is driven to move the holding plate 87 forward. Then, the operation inclined surface 160 provided on the holding plate 87 releases the pressing of the arm member 156, and as shown in FIGS. 18 and 20, all the reference magnetic members 150 are biased by the reference magnetic member biasing springs. Then, the bar holding mechanism 80 exceeds the receiving position, and the operating pin 124 is lowered along the retracting conversion member 131 as shown in FIG. 14, and the holding block 97 is lowered by its own weight. The other side descends, and moves forward together with the receiving block 96 in the one side descending state.

  When there is a bar B stored in the cassette 50, the bar holding mechanism 80 moving forward moves the contact part 133 of the receiving block 96 to the end of the bar B already stored in the cassette 50. As a result, the receiving block 96 is raised to one side by the urging force of the receiving block urging spring as shown in FIG. Both the blocks 97 escape upward from the bar B.

  When there is no bar B already stored in the cassette 50, the bar holding mechanism 80 moving forward moves the operating pin 116 up by the up conversion member 135 as shown in FIG. Then, the receiving block 96 is swung upward, and the receiving block urging spring urges one side to rise, and both the receiving block 96 and the holding block 97 move upward.

  When the holding plate 87 is detected by the front end position sensor, the control unit 31 determines that the bar holding mechanism 80 has reached the front end position, and stops and reverses the motor 90. Then, the holding plate 87 moves rearward, and all the bar metal holding mechanisms 80 keep the receiving block 96 in the one side raised state, that is, the receiving block 96 and the holding block 97 are moved upward from the bar B of the cassette 50. Move backwards in the state of being escaped. As a result, all the bar metal holding mechanisms 80 move backward without contacting the bar B. At the time of the backward movement, as shown in FIG. 22, the magnetic data detection unit 142 passes the bar B between the pair of magnetic sensors 140 and 141. The magnetic data detector 142 detects the magnetic data of the bar B stored in the cassette 50. When the holding plate 87 is detected by a receiving position sensor (not shown), the control unit 31 moves the length of the cassette 50 so as to scan all the bars B existing in the storage spaces of all the cassettes 50. It is determined that all the magnetic data detection units 142 have moved once over the entirety and the bar holding mechanism 80 has reached the receiving position, and the motor 90 is stopped. If a mistake occurs in detection, the magnetic data detection unit 142 is moved a plurality of times once again, that is, over the entire length of the cassette 50.

  The control unit 31 is based on the magnetic data detected by all the magnetic data detection units 142, and the different denomination bars including the abnormal state in which the presence or absence of a normal bar and the type of bar cannot be specified. Check for the presence or absence of gold, the presence or absence of abnormal posture of the loaded bar, and the amount of normal bar.

  Here, the magnetic data detection unit 142 scans the magnetic data of the bar B when the holding plate 87 is moved rearward, and sets the magnetic data detection interval to a predetermined equal interval. B and the gap between the magnetic sensor 141 and the bar B are detected. As shown in FIG. 23, the detection interval is, for example, an interval at which four or five detection points (for example, seven points in FIG. 23) are detected for one bar B, that is, from the detected gap. The detection interval is set such that an arc (outlined in FIG. 23) that is the outer shape of the bar B can be detected.

  As described above, the confirmation unit 31a detects the detection data of each magnetic data detection unit 142 or the detection of each magnetic data based on the correction value obtained immediately before the confirmation operation and stored in the storage unit for each magnetic data detection unit 142. After the matching determination data (described later) for the unit 142 is corrected and temperature compensation is performed, the detected magnetic data and the matching determination data are compared. That is, the matching determination data corrected by the correction value is compared with the detected magnetic data, or the value corrected by the correction value of the detected magnetic data is compared with the matching determination data.

  Further, the confirmation means 31a obtains an upper arc that is one side in the diameter direction of each bar B based on the detected magnetic data, that is, the gap between the magnetic sensor 140 and the bar B, and the magnetic sensor 141 and the bar B The arc on the lower side, which is the other side in the diameter direction of the bar B, is obtained on the basis of the gap. More specifically, as shown in FIG. 24, gaps are arranged at detection timing intervals by the magnetic data detection unit 142, and a perfect circular arc C1 approximating a curve K1 passing through an end of the upper gap and a lower side A perfect circular arc C2 approximating the curve K2 passing through the end of the gap is obtained individually. For the sake of illustration, only the upper gap and the curve K1 based on this gap are shown in the graph of FIG. 24. However, a perfect circle that approximates the lower gap and the curves K2 and K2 based on the lower gap. The arc C2 is obtained by vertically inverting the curve K1 and the arc C1 based on the upper gap shown in FIG. 24 shows a case where the gap detection interval is set narrower than that in FIG. 23 for convenience of illustration.

  The confirmation unit 31a further specifies matching determination data that minimizes an error with respect to the arcs C1 and C2 from the matching determination data of the denominations stored in advance in the storage unit. The matching determination data is stored in advance in the storage unit as arc data of a regular bar type. The denomination of the bar B is specified by specifying the matching determination data. When all the matching determination data deviates from the arcs C1 and C2 by a predetermined error or more, it may be detected as an abnormal state in which any normal bar metal denomination cannot be specified, or a magnetic sensor. You may comprise so that the abnormal state of 140,141 may be detected.

  When the upper arc C1 and the lower arc C2 are obtained, the confirmation unit 31a obtains the arc center position T1 of the upper arc C1 and the arc center position T2 of the lower arc C2, respectively. These arc center positions T1 and T2 can be obtained based on, for example, the curvature of arcs C1 and C2 and the positions of arcs C1 and C2.

  Next, the confirmation unit 31a determines whether or not the arc center position T1 of the upper arc C1 matches the arc center position T2 of the lower arc C2. As a result of this determination, when it is determined that the arc center positions T1 and T2 match, more specifically, the arc center position T1 of the upper arc C1 and the arc center position T2 of the lower arc C2 Is within a predetermined range, it is determined that the bar B is loaded in the cassette 50 in an appropriate posture.

  Here, as shown in FIG. 25, in the case of an abnormal posture in which the radial direction of the bar metal B is arranged obliquely with respect to the length direction of the cassette 50 (indicated by a one-dot chain line in FIG. 25), the bar B The cross section along the length direction of the cassette 50 is an ellipse along the length direction of the cassette 50. Then, when the arcs C1 and C2 of perfect circles that approximate the curves K1 and K2 passing through the end portions of the gap are obtained based on the gap obtained for the slanted bar B, the major axis of the ellipse is about Alternatively, perfect circular arcs C1 and C2 having a diameter longer than the major axis are obtained. However, since it is actually an ellipse arc, when the arc center position T1 of the upper perfect circle arc C1 and the arc center position T2 of the lower true arc C2 are obtained and compared, these arc centers For example, as shown in FIG. 26, the gaps are shifted along the gap measurement direction due to the difference between the major axis and the minor axis of the ellipse. That is, by determining that the cross section of the bar B is an ellipse based on the positional deviation between the arc center positions T1 and T2 of the upper and lower perfect circular arcs C1 and C2 based on the gap. It is possible to detect that the bar B is in an abnormal posture.

  The confirmation means 31a determines that the arc center position T1 of the upper arc C1 and the arc center position T2 of the lower arc C2 match, that is, the attitude of the bar B is not an abnormal attitude due to oblique loading but a normal attitude. In some cases, the different denomination is determined based on the matching determination data specified based on the arc C1 or the arc C2. More specifically, the arc based on the matching determination data is compared with the arc of the denomination to be loaded in the cassette 50, that is, the arc based on the magnetic data of the reference magnetic member 150. While it is determined that the bar metal B is the same denomination, when it is determined that the arcs do not match, it is determined that the bar B is a different denomination.

  In addition to the abnormal posture described above, the confirmation unit 31a detects an abnormal posture due to pinching between adjacent metal bars B, B or the like. The confirmation means 31a obtains the arc center positions T1,..., T2... Based on the gaps for all the bars B loaded in the cassette 50 based on the magnetic data detected by the magnetic data detection unit 142. Whether or not the interval L (see FIG. 24) between the arc center positions T1 and T1 or the arc center positions T2 and T2 of the bars B adjacent to each other along the length direction is constant, more specifically, in the cassette 50. It is determined whether or not it is about the diameter of the denomination bar B to be loaded. Here, when the distance L between the arc center positions T1 and T1 or the arc center positions T2 and T2 of the adjacent metal bars B along the length direction of the cassette 50 is not constant, for example, A foreign object such as a coin may be sandwiched between the bar B. When the confirmation means 31a determines that the distance L between the arc center positions T1 and T1 or the arc center positions T2 and T2 of the adjacent metal bars B is not constant, the bar metal B has an abnormal posture due to pinching of loose coins or the like. Detect that there is.

  When the different denomination bar is detected by the confirmation unit 31a and when the abnormal posture of the bar B is detected, the identification unit 31b (see FIG. 2) of the control unit 31 determines the different denomination and abnormal posture. The position of the bar B is specified. The position of the bar is specified by, for example, the name of the denomination to be loaded set in the corresponding cassette 50 and the number of the corresponding cassette 50 loaded from the front side on one side in the length direction. Etc. When a different denomination or an abnormal posture of the bar B is detected, the position of the bar B specified by the specifying means 31b is displayed together with a message indicating that the different denomination or an abnormal posture of the bar B is detected. Displayed on the part 32. Thereafter, when the different denomination bar is removed by the person in charge, or when the correcting operation of the abnormally-positioned bar B is performed, the above-described different denomination or abnormal posture is detected again, and the different denomination or The detection of the different denominations or abnormal postures and the correction operation by the person in charge are repeated until the abnormal posture of the bar B is eliminated.

  And when there is no different denomination or abnormal posture, the count value of the normal bar for each cassette 50, which is the confirmation result for all the cassettes 50 executed in parallel, is stored in the storage unit and the display unit 32 Will be displayed. Thereby, the head height confirmation process is completed.

  Therefore, according to the bar metal storage device 10 of the first embodiment described above, a predetermined magnetic sensor (for example, the magnetic sensor 140) of the pair of magnetic sensors 140 and 141 supported by the carrier 91 is predetermined by the confirmation unit 31a. The arc center position T1 is obtained based on the gap between one magnetic sensor 140 and the bar B detected at the interval, and based on the gap detected at a predetermined interval by the other magnetic sensor (for example, the magnetic sensor 141). When the arc center position T2 is obtained and the arc center positions T1 and T2 coincide with each other, that is, when the combination of one and the other arcs C1 and C2 can be regarded as a substantially perfect circle which is a cross section of a normal bar. The magnetic data detected by the magnetic data detector 142 and the magnetic data of the normal bar stored in advance, that is, the magnetic data Since the outer shape (arc) of the bar B detected by the detection unit 142 and the outer shape (arc) of the reference magnetic member 150 can be compared to determine whether or not the bar B is of a different denomination, It is possible to accurately detect the seed bar B.

  Furthermore, one and the other arc center positions T1 and T2 based on the arcs C1 and C2 detected by the pair of magnetic sensors 140 and 141 are mutually equal, for example, because the bar B is inclined with respect to the alignment direction. If they do not match, the confirmation means 31a can detect that the bar B is in an abnormal posture. For example, the posture of the bar B can be corrected to an appropriate posture according to the detection result. Judgment can be made.

Further, whether the interval between the arc center positions T1, T1 of the arcs C1, C1 adjacent to each other along the length direction of the cassette 50 detected by the magnetic data detection unit 142 or the arc center positions T2, T2 of the arcs C2, C2 is constant. That is, it is determined whether or not the interval L between the bars B loaded in parallel in the length direction of the cassette 50 is constant, and if the interval L is not constant as a result of this determination, Since the abnormal posture of B can be detected, for example, the posture of the bar B can be corrected to an appropriate posture according to the detection result, and as a result, accurate different denomination determination can be performed.
Further, since the position of the different denomination bar or the abnormally shaped bar B can be specified by the specifying means 31b, the removal of the different denomination bar or the abnormal position of the bar B is quickly corrected to an appropriate position. The person in charge can be clearly informed of the treatment and prompted.

  Next, a bar storage device according to a second embodiment of the present invention will be described with a focus on differences from the first embodiment with reference to the drawings. Note that the bar metal storage device 10 in the second embodiment is different only in the method of determining the denomination and detecting the abnormal posture of the bar B, and therefore, the same reference numerals are given to the same parts as in the first embodiment. The description is omitted.

As in the first embodiment, the bar metal storage device 10 of the present embodiment receives a height confirmation operation for confirming the height of normal bar metal for all cassettes 50 via the operation unit 30. Then, the presence confirmation process is started by the confirmation unit 31a of the control unit 31, and first, a correction value calculation process is performed.
Next, when the motor 90 is driven by the control unit 31 to move the holding plate 87 forward and reach the front end position, the motor 90 is stopped and reversely rotated to move the holding plate 87 backward. At this time, all the magnetic data detectors 142 are caused to detect the magnetic data of the bar B stored in the cassette 50.

  When the holding plate 87 is moved backward, the magnetic data of the bar B is scanned, and the detection interval of the magnetic data by the magnetic data detection unit 142 is set to a predetermined equal interval. The gap between the magnetic sensor 140 and the bar B , And a gap between the magnetic sensor 141 and the bar B is detected. The detection interval at this time is shown in FIG. 23 as in the first embodiment. For example, four or five detection points are detected for one bar B (for example, FIG. 23 shows a case of seven points). ). The gap detection is preferably performed continuously, that is, the detection interval is narrow.

Then, the magnetic data detected by all the magnetic data detection units 142 is compared with the magnetic data of the normal bar metal stored in the storage unit in advance. The presence or absence of a different denomination bar that includes an abnormal state that could not be identified, the presence or absence of an abnormal posture in the loaded state of the bar, and the amount of normal bar are confirmed.
More specifically, as shown in FIG. 23, the minimum gap Gs is obtained from the gaps detected by the one magnetic sensor 140 at a predetermined equal interval with respect to one bar B, and the other magnetic sensor is obtained. Among the gaps detected at predetermined equal intervals in step 141, the minimum gap Gs is obtained. Then, the diameter (outer diameter) of the bar B is obtained from the one minimum gap Gs and the other minimum gap Gs and the predetermined distance Ls between the magnetic sensors 140 and 141. Next, the obtained diameter of the bar B and the diameter of the normal bar B based on the magnetic data of the reference magnetic member 150 corresponding to the denomination to be loaded in the cassette 50 loaded with the bar B are obtained. In comparison, the different denomination of one bar B is determined.

  The confirmation means 31a is a bar along the direction perpendicular to the gap measurement direction described above based on the magnetic data (see FIG. 24) detected by the magnetic sensors 140 and 141, that is, along the moving direction of the magnetic sensors 140 and 141. The outer diameter R1 of the gold B is obtained, and the outer diameter R1 is compared with the outer diameter (diameter) of the bar B obtained based on the above-described minimum gap Gs. As a result of this comparison, when it is determined that the outer diameter R1 in the direction along the moving direction of the magnetic sensors 140 and 141 is larger, it is detected that the bar B is in an abnormal posture. This is because the cross-sectional shape of the detected bar B along the moving direction of the magnetic sensors 140 and 141 is an ellipse along the moving direction of the magnetic sensors 140 and 141, and is the same as in the first embodiment. This is because the bar B is loaded obliquely. When the diameter based on the minimum gap Gs matches the outer diameter R1, the confirmation unit 31a determines that the bar B is in a normal posture.

  When the different type of metal rod B is detected and when the abnormal posture of the metal rod B is detected, the position of the different metal type and the abnormal posture of the metal rod B is specified by the specifying means 31b. As in the first embodiment, the display unit 32 notifies the person in charge. Further, when the removal of the different denomination bar and the abnormal posture of the bar B are resolved, the height of all the cassettes 50 is confirmed, and the count value of the normal bar for each cassette 50 is displayed on the display unit 32. The high confirmation process is finished. As in the first embodiment, the position of the different denomination and the abnormally-positioned bar metal B may be specified by the specifying unit 31b.

  Therefore, according to the bar metal storage device 10 of the second embodiment described above, one minimum gap Gs and the other minimum gap Gs by the pair of magnetic sensors 140 and 141, and the predetermined distance Ls between the magnetic sensors 140 and 141, The denomination is specified based on the outer diameter of the bar B obtained from the above, and it is determined whether or not the bar B is a different denomination based on the specified denomination. Since the process to specify can be simplified, the different denomination can be quickly determined.

  In addition, about the above, by calculating | requiring the diameter of this metal rod B from the minimum gap Gs and the predetermined distance Ls among the gaps detected by predetermined equal intervals, the diameter of this metal rod B calculated | required, and the said bar | burr Compare the diameter of the normal bar B based on the magnetic data of the reference magnetic member 150 corresponding to the denomination to be loaded in the cassette 50 loaded with the gold B, and determine the different denomination of one bar B To do. However, the present invention is not limited to this, and this comparison target range may be expanded. That is, of the gaps detected at predetermined equal intervals, not only the minimum gap Gs is used as gap data, but the total value of the gaps is obtained from all the detected gaps, or conversely from the specified distance Ls. It is also possible to obtain and use all the sums (bar chord portions) of the values obtained by subtracting each detected gap. As described above, it is preferable that the gap detection is performed continuously, that is, the detection interval is narrower, and it is possible not only to obtain an accurate minimum gap Gs, but also to obtain the sum of these values as an area. You will also be able to. In other words, the larger the total value, the greater the difference in the denomination of the bar B, so that the accuracy of the different denomination determination can be further improved. And when judging using these total values, what is necessary is just to compare any one of these total values with the predetermined value which concerns on the normal bar | burr B previously memorize | stored in the memory | storage part.

  Further, based on the magnetic data detected by the magnetic sensors 140 and 141, the outer diameter in the gap direction is compared with the outer diameter R1 in the moving direction of the magnetic sensors 140 and 141 perpendicular to the outer diameter, based on the gap. When the outer diameter and the outer diameter R1 in the moving direction of the magnetic sensors 140 and 141 do not coincide with each other, for example, the bar B is loaded obliquely with respect to the length direction of the cassette 50. Since it is possible to detect that the gold B is in an abnormal posture, for example, the posture of the bar B can be corrected to an appropriate posture in accordance with the detection result, and as a result, accurate different denomination determination can be performed. .

  In the embodiment described above, the bar metal storage device 10 that is provided in parallel with the coin depositing and dispensing machine 11 and generates the bar metal B from the rose coin and stores it has been described as an example. Of course, the present invention can also be applied to a bar payment machine that is loaded during work and only dispenses money.
