A pair of caulking claws 64 and 65 are provided which are moved close to and away from each other in the vertical direction by actuation of a vertical claw claw vertical operation cam that is driven. That is, the wrapping paper 45 has a width dimension larger than the height of the accumulated coins, and the pair of crimping claws 64 and 65 are moved in the proximity direction by the operation of a crimping claw vertical operation cam (not shown). Then, the portion of the wrapping paper 45 wound around the accumulated coins that protrudes up and down from the accumulated coins is crimped so as to be rounded inward.

  When the packaged wrapping coin is dropped downward, the wrapping roller 43c is separated from the wrapping rollers 43a and 43b by the operation of a wrapping roller opening / closing cam (not shown) driven by the cam motor 51 shown in FIG. The group 44 is opened, and the wrapping coins by the wrapping rollers 43a, 43b, and 43c are released, and the support bar 41 is also driven by the cam motor 51, and the wrapping roller group 44 is actuated by a support arm relief cam (not shown).

Below the packaging unit 30, a roll chute (not shown) that accepts a wrapping coin in which an appropriate number of accumulated coins are wrapped with a wrapping paper 45, a reject box (not shown) that accepts a wrapping coin when the number of accumulated coins is not appropriate, A gate (not shown) that distributes the wrapping coins to a roll chute or a reject box is provided. The distribution direction of the gate is switched by a gate solenoid 66 shown in FIG.

  In the present embodiment, the magnetic sensor 70 and the side of the wrapping roller group 44, specifically, the gap between the wrapping rollers 43b and 43c where the caulking claws 64 and 65 and the support arm 55 do not advance and retract, An elevating mechanism 71 is provided for moving the magnetic sensor 70 in the up-down direction, that is, in the accumulation direction (axial direction) of the accumulated coins in a state where the detection surface 70a faces the circumferential surface of the accumulated coins. . The magnetic sensor 70 detects a voltage that changes according to the magnetic property of the detection target as magnetic data. The magnetic sensor 70 determines an excess / deficiency detection unit (control means) 72 shown in FIG. Detection means) 73 is configured.

  The excess / deficiency detection control unit 72 includes an amplification circuit 75 that amplifies the output signal of the magnetic sensor 70, a microcomputer 76 that compares the output signal of the magnetic sensor 70 amplified by the amplification circuit 75, data for excess / deficiency determination, and the like. And a storage unit 77 for storing. The storage unit 77 stores a predetermined reference value and a reference range that are used when the output signal of the magnetic sensor 70 is compared. That is, for example, between the start reference value for determining the start of detection of the accumulated coin by the magnetic sensor 70, the end reference value for determining the end of detection of the accumulated coin by the magnetic sensor 70, and the coin c shown in FIG. A coin gap detection reference value for determining that there is a coin gap s, a thickness reference value for determining a deformed coin as an abnormality, and whether or not the thickness of the coin c is appropriate. The thickness reference range, the packaging reference number that is the unit number of wrapping coins, and the coin gap reference range for determining whether or not the size of the coin gap s is appropriate for each denomination of the coin c And is stored in the storage unit 77 in advance.

  The elevating mechanism 71 elevates and lowers the magnetic sensor 70 in the vertical direction by the operation of an elevating mechanism operating cam (not shown) driven by the cam motor 51 shown in FIG. The elevating mechanism 71 supports the magnetic sensor 70 so that the magnetic sensor 70 can be moved over the entire range in the axial direction of the stacked coins supported by the support rod 41 and sandwiched between the packaging rollers 43a, 43b, and 43c, and a predetermined range on both sides. doing.

  Then, the wrapping paper 45 is wound around the stacked coins that are positioned in the stacking direction by being supported by the support bar 41 and are aligned in the radial direction by being sandwiched by the packing rollers 43a, 43b, and 43c. Before, the magnetic sensor 70 is moved from the position outside the one end in the stacking direction of the stacked coins to the position outside the other end in the stacking direction by the lifting mechanism 71, and the excess / deficiency detection control unit 72 is obtained in the meantime. From the output signal of the magnetic sensor 70, it is determined whether or not the accumulated coins are excessive or insufficient. Specifically, the magnetic sensor 70 is moved from a predetermined standby position above the upper end of the accumulated coin C as shown by a solid line in FIG. 3, and from the lower end of the accumulated coin C as shown by a two-dot chain line in FIG. The excess / deficiency detection control unit 72 determines whether or not the accumulated coins C are excessive or insufficient from the output signal of the magnetic sensor 70 during this period. Of course, the predetermined position below the lower end of the accumulated coin C is set as the standby position, and the accumulated coin is determined from the output signal of the magnetic sensor 70 while moving from the standby position to the predetermined upper end position above the upper end of the accumulated coin C. Whether or not C is excessive or insufficient may be determined.

  The excess / deficiency detection control unit 72 is connected to an overall control unit 80 that controls the entire coin wrapping machine 10. Connected to the overall control unit 80 are an operation unit 81 where an operation is input by an operator, an image display unit 82 that outputs an image toward the operator, a voice output unit 83 that outputs a sound toward the operator, and the like. ing.

  In the coin wrapping machine 10 having the above configuration, when the denomination of the wrapping coin to be wrapped is set and input via the operation unit 81, the overall control unit 80 has insufficient or insufficient designated denomination data indicating this designated denomination. It outputs to the detection control part 72.

  Then, the coin c of the designated denomination is basically put into the rotating disk 11, and when an operation input for starting packaging is input to the operation unit 81 in this state, the overall control unit 80 sends The motor 15 is driven. Then, the rotating disk 11 and the belt mechanism 13 are rotated, and the coins c in the rotating disk 11 are sent out one by one toward the coin path 12 by the centrifugal force and the overlapping restriction by a passage restriction unit (not shown), In the coin path 12, the belt mechanism 13 transfers the sheets one by one toward the stacking unit 23. Then, the coin identifying unit 20 identifies the authenticity and denomination of the coin c, and performs counting and feeding timing detection.

  When the coin c identified as the true designated denomination by the coin identifying unit 20 is supplied to the accumulating unit 23, the overall control unit 80 intermittently drives the drum motor 26 based on the detection timing of the coin identifying unit 20. Will do. As a result, the coins c are stacked in a stacked state on the protrusions 24 of the pair of stacking drums 25 at the standby position. When the coin identification unit 20 counts the number of coins c of the designated denomination, the overall control unit 80 stops the coin c next to the last coin c by the sending stopper 14 and stops the sending motor 15. The rotating disk 11 and the belt mechanism 13 are stopped until the production of the next wrapping coin can be started.

  If a false coin or a coin of a different denomination is detected by the above-described coin identifying unit 20 during the feeding to the stacking unit 23, the overall control unit 80 stops the coin by using the sending stopper 14, for example. At the same time, the delivery motor 15 is stopped to stop the rotary disk 11 and the belt mechanism 13, and an alarm to that effect is generated in the image display unit 82 and the audio output unit 83.

  As described above, after the coin identification unit 20 detects the last coin c of the packaging standard number of the designated denomination, the coin c is stacked on the already accumulated coins on the protrusion 24 of the accumulation drum 25. When the time necessary for this has elapsed, the overall control unit 80 further rotates the stacking drum 25 by the drum motor 26 to close the passing hole 34 of the entrance preventing shutter 31 with the stacked coins C on the protrusions 24. Delivered onto the shutter member 35. Thereafter, the overall control unit 80 stops the drum motor 26 and drives the cam motor 51 at the timing when the accumulation drum 25 becomes the standby position. Then, the packaging roller group 44 is opened by the operation of the packaging roller cam (not shown), and the shutter member 35 of the entry preventing shutter 31 is opened. As a result, the accumulated coin C passes through the passage hole 34 of the entry preventing shutter 31 and is placed on the support bar 41 that has been waiting at the raised position.

  With the subsequent drive of the cam motor 51, the support bar 41 is lowered in the vertical direction by the operation of a support arm vertical operation cam (not shown), and stops at a predetermined packaging position. Thereby, the accumulated coins C are arranged between the three packaging rollers 43a, 43b, 43c of the packaging roller group 44 in the open state.

  When the cam motor 51 is subsequently driven, the wrapping roller 43c is brought close to the wrapping rollers 43a and 43b by the operation of the unillustrated wrapping roller opening / closing cam. The wrapping rollers 43a, 43b and 43c allow the accumulated coins C to be moved in the three radial directions. Hold from.

  With the subsequent drive of the cam motor 51, the lifting mechanism 71 operates the lifting mechanism operation cam (not shown) to move the magnetic sensor 70 from the standby position above the upper end of the accumulated coin C to the lower end position below the lower end of the accumulated coin C. It is moved at a predetermined constant speed. Then, the excess / deficiency detection control unit 72 detects an output signal value (voltage) for each movement distance of the magnetic sensor 70 obtained during the movement of the magnetic sensor 70 from the standby position as shown in FIG. The presence or absence of excess or deficiency is determined from the output signal value. Since the magnetic sensor 70 moves at a constant speed, an output signal value for each movement time may be used.

  That is, the excess / deficiency detection control unit 72 corresponds to the designated denomination data according to the designated denomination data output from the overall control unit 80 based on the setting of the denomination to be packaged in the operation unit 81 described above. The reference value and reference range of the denomination to be selected are selected from the storage unit 77 and read out, and the amount of change in the output signal value of the magnetic sensor 70 from the state where the magnetic sensor 70 is in the standby position corresponds to the specified denomination data. When the denomination predetermined reference value of the denomination is reached, the detection start of the accumulated coins C is determined, and the position of the magnetic sensor 70 at the time of detection start determination is set to the detection start position (L0 shown in FIG. 4).

  Then, after the above-described detection start determination, the excess / deficiency detection control unit 72 determines that the outer peripheral surface of the first coin c is detected when the output signal value of the magnetic sensor 70 decreases to a minimum value, and outputs When the signal value rises from this minimum value, and the amount of change from this minimum value (ΔV shown in FIG. 5) becomes the predetermined coin gap detection reference value of the denomination corresponding to the designated denomination data (see FIG. 4). (The position of L1 shown), it is determined that there is a coin gap s between coins c, and the count is performed. Next, it is determined that the outer peripheral surface of the next coin c is detected when the amount of change in the output signal value falls without reaching a predetermined end reference value larger than the coin gap detection reference value and falls to a minimum value, When the output signal value rises from this minimum value, and the amount of change from this minimum value becomes the coin gap detection reference value (position L2 shown in FIG. 4), it is determined that there is a next adjacent coin gap s and the count is made. The amount of change in the output signal value decreases again without reaching the end reference value, and when the output signal value decreases to the minimum value, it is determined that the outer peripheral surface of the next coin c is detected, and increases from this minimum value. When the amount of change from the reference value becomes the coin gap detection reference value (the position of L3 shown in FIG. 4), it is determined that there is a next adjacent coin gap s, and the count is performed. Detection and counting of the outer circumferential surface of the coin c and the coin gap s between the coins c are sequentially performed, and finally, the designated denomination data whose change from the immediately preceding minimum value is larger than the coin gap detection reference value. When the predetermined end reference value of the corresponding denomination is reached (Le position shown in FIG. 4), the end of detection of the accumulated coins C is determined.

  That is, the excess / deficiency detection control unit 72 determines the number of coins of the accumulated coins C based on the output signal of the magnetic sensor 70 and the movement distance of the magnetic sensor 70 in the detection period from the detection start determination timing to the detection end determination timing. The number of coin gaps s is counted by detecting the coin gap s and the outer circumferential surface from the difference in the output signal values between the coin gap s and the outer circumferential surface of the coins c. .

  The excess / deficiency detection control unit 72 stores all the coin gaps s detected in the detection period in the storage unit 77 in association with movement distance information of the magnetic sensor 70 that moves at a constant speed in the detection period. The distance between adjacent coin gaps s, which is the movement distance of the magnetic sensor 70, from the detection of one coin gap s to the detection of the next coin gap s adjacent to the downstream side in the movement direction (see FIG. 5). All indicated n) are compared with a predetermined thickness reference value of the denomination corresponding to the designated denomination data (for example, a value of 90% of the distance between normal coin gaps s). When the distance between any adjacent coin gaps s is smaller than the thickness reference value, it is determined that an abnormally deformed coin (crushed coin) is mixed, while the distance between all adjacent coin gaps s. Is equal to or greater than the thickness reference value, it is determined that no deformed coins are mixed. If it is determined that the deformed coins are mixed, the excess / deficiency detection control unit 72 causes the image display unit 82 and the audio output unit 83 to output an alarm to that effect.

  Further, the excess / deficiency detection control unit 72 determines that at least one of the two distances between the three coin gaps s is the specified money for all combinations of the three consecutive coin gaps s based on the distance between the coin gaps s described above. The denomination corresponding to the designated denomination data is smaller than the predetermined thickness reference value of the denomination corresponding to the seed data, and the distance between the first coin gap s and the third coin gap s is When the value is within the predetermined thickness reference range, it is determined that the central coin gap s of the three consecutive coin gaps s is not a coin gap s between coins c but a flaw. Naturally, this scratch is not counted as the coin gap s.

  Moreover, the excess / deficiency detection control unit 72 determines the presence / absence of a different denomination coin as an abnormality from the output signal of the magnetic sensor 70 between the above-described coin gaps s. That is, in the output signal, the distance between the coin gaps s, which is the movement distance of the magnetic sensor 70, from the detection of one coin gap s to the detection of the next coin gap s adjacent to the downstream side in the movement direction. All are compared with a predetermined thickness reference range of the denomination corresponding to the designated denomination data. When the distance between any of the coin gaps s is outside the thickness reference range, it is determined that the different denomination coins are mixed as abnormal, while the distance between all the coin gaps s is the thickness reference. If it is within the range, it is determined that no foreign coins are mixed. If it is determined that different denomination coins are mixed, the excess / deficiency detection control unit 72 causes the image display unit 82 and the audio output unit 83 to output an alarm to that effect.

  Further, the excess / deficiency detection control unit 72 is a movement distance of the magnetic sensor 70 from the detection of one coin gap s in the output signal to the detection of the next coin gap s adjacent to the downstream side in the movement direction. All the distances between certain coin gaps s are compared between adjacent ones. Then, if the difference between the adjacent items is outside the predetermined difference reference range of the denomination corresponding to the designated denomination data, it is determined that the different denomination coin is mixed as an abnormality. On the other hand, if all are within the difference reference range, it is determined that no different denomination coins are mixed. If it is determined that different denomination coins are mixed, the excess / deficiency detection control unit 72 causes the image display unit 82 and the audio output unit 83 to output an alarm to that effect.

  Moreover, whenever the excess / deficiency detection control part 72 detects the coin gap s between the coins c, the movement distance (w shown in FIG. 5) of the magnetic sensor 70 while detecting one coin gap s is calculated. It compares with the predetermined coin gap reference value of the denomination corresponding to the designated denomination data. If the movement distance of the magnetic sensor 70 is larger than the coin gap reference value for any coin gap s, it is determined that a deformed coin (folded coin) is mixed as an abnormality, while all the coin gaps s are magnetic. If the moving distance of the sensor 70 is equal to or less than the coin gap reference value, it is determined that no deformed coin is mixed. If it is determined that the deformed coins are mixed, the excess / deficiency detection control unit 72 causes the image display unit 82 and the audio output unit 83 to output an alarm to that effect. That is, as shown in FIG. 4, when the folded coin c1 is mixed in the accumulated coin C, the moving distance w shown in FIG. 5 during the detection of the coin gap s is increased. By detecting w, a deformed coin is detected.

  Then, the excess / deficiency detection control unit 72 sets the number obtained by adding 1 to the number of coin gaps s counted in the detection period as the accumulated coin detection number, and sets the accumulated coin detection number as a predetermined packaging reference number. To determine whether the number of accumulated coins C is excessive or insufficient. In other words, if the number of accumulated coins detected matches the predetermined packaging reference number of denominations corresponding to the specified denomination data, it is determined that there is no excess or deficiency in the number of accumulated coins C. If the package reference number does not match, it is determined that the number of coins of the accumulated coins C is excessive or insufficient, and an alarm to that effect is output by the image display unit 82 and the audio output unit 83.

  Then, the excess / deficiency detection control unit 72 indicates that the accumulated coins C are normal in the overall control unit 80 when neither the deformed coins nor the different denomination coins are mixed, and the accumulated coins C have no excess or deficiency. On the other hand, when either a deformed coin or a different denomination coin is mixed, or when the number of coins in the accumulated coin C is excessive or insufficient, the accumulated coin C is abnormal in the overall control unit 80. A signal to that effect is output. When the overall control unit 80 receives a signal indicating that the accumulated coins C are normal, the gate solenoid 66 switches the gate to the roll chute side. When receiving a signal indicating that the accumulated coins C are abnormal, the overall control unit 80 causes the gate solenoid 66 to Switch the gate to the reject box side.

  At the timing when the magnetic sensor 70 moves to the lower end position, the overall control unit 80 drives the wrapping paper supply motor 59 shown in FIG. 2 to collect the wrapping paper 45 by the wrapping paper supply roller 58, the coins C and the wrapping roller group 44. 2, and then the wrapping roller group 44 is rotated by driving the wrapping motor 50 shown in FIG. 2, whereby the wrapping paper 45 is wound around the circumferential surface of the accumulated coins C and the wrapping paper supply motor 59 is stopped. Thus, the wrapping paper 45 is cut by the cutter 60.

  Further, by the drive of the cam motor 51 performed subsequently, the pair of crimping claws 64 and 65 are inserted above and below the accumulated coins C by the operation of the crimping claw relief cam (not shown) and also driven by the cam motor 51. A pair of caulking claws 64 and 65 are brought close to each other by actuation of a caulking claw vertical operation cam not shown. Thereby, a pair of crimping claws 64 and 65 are crimped so that the part which protrudes up and down from the accumulation coin C of the wrapping paper 45 wound around the accumulation coin C may be rounded inside. The wrapping roller opening / closing cam (not shown) is actuated by the drive of the cam motor 51 to open the wrapping roller group 44, and the support bar 41 is moved from the wrapping roller group 44 by the actuating of the support arm relief cam (not shown) that is also driven by the cam motor 51. It escapes in the lateral direction to separate. Thereby, if it is the wrapping coin which packaged the normal accumulation coin C, it will fall to a roll chute, and if it is the packaging coin which wrapped the abnormal accumulation coin C, it will fall to a reject box.

  According to the coin wrapping machine 10 of the present embodiment described above, the magnetic sensor 70 moves in the stacking direction with respect to the stacked coins C stacked in the stacked state by the stacking unit 23, and the circumference of the stacked coins C is increased. When the magnetic data is detected on the detection surface 70a facing the surface, the excess / deficiency detection control unit 72 determines whether the number of coins is excessive or insufficient as an abnormality of the accumulated coins C based on the output signal of the magnetic sensor 70. Thus, since the output signal of the magnetic sensor 70 is used, it is possible to detect the influence of the deformed coin, and thus it is possible to eliminate the influence of the deformed coin. Therefore, even if deformed coins are mixed, it is possible to appropriately determine whether or not the number of accumulated coins C is excessive or insufficient. In other words, if the accumulated coin C is used to determine whether the number of accumulated coins is excessive or insufficient, even if the number of coins is insufficient, the deformed coins are mixed and the total length of the accumulated coins C is increased. Although it may be determined that the number of coins is appropriate, such erroneous determination can be prevented. Further, if it is determined whether the number of accumulated coins is excessive or insufficient based on the length of the accumulated coins C, the length of the accumulated coins is not affected by the distribution of a part of the accumulated coins in which the appropriate number of accumulated coins are accumulated. When it is packaged in a state where deformed coins that affect the condition are mixed, it may be determined that there is an excess or deficiency and this may be eliminated, but such erroneous determination can also be prevented. .

  Further, the excess / deficiency detection control unit 72 detects the coin gap s between the coins c of the accumulated coins C from the output signal of the magnetic sensor 70, and the presence / absence of the excess or deficiency of the number of coins of the accumulated coins C from the number of the coin gaps s. Therefore, compared with the case of determining whether the number of coins is excessive or insufficient from the total length of the accumulated coins C, the influence of deformation and wear is less likely to be affected. It is possible to accurately determine whether the number of coins is excessive or insufficient.

  Further, the excess / deficiency detection control unit 72 determines the detection start of the accumulated coin C when the change amount of the output signal value of the magnetic sensor 70 reaches a predetermined start reference value, and when it reaches a predetermined end reference value. Since the end of detection of the accumulated coins C is determined, it is possible to determine whether the number of coins of the accumulated coins C is excessive or insufficient from the output signal of the magnetic sensor 70 in an appropriate detection period from the start of detection to the end of detection. .

  Further, the excess / deficiency detection control unit 72 determines that there is a coin gap s between the coins c when the amount of change in the output signal value of the magnetic sensor 70 in the detection period becomes a predetermined coin gap detection reference value. The coin gap s between the coins c can be detected appropriately.

  Moreover, since the coin gap detection reference value is predetermined and stored for each denomination of the coin c, the coin gap s between the coins c can be detected appropriately for each denomination.

  Moreover, since the coin gap detection reference value is selected in accordance with the setting of the denomination to be wrapped, the coin gap s between the coins c of the selected set denomination can be detected appropriately.

  Further, the excess / deficiency detection control unit 72 determines that the abnormally deformed coin (crushed coin) is mixed when the distance between the coin gaps s, that is, the thickness of the coin c is smaller than a predetermined thickness reference value. It is possible to properly detect the mixing of the deformed coins.

  Further, the excess / deficiency detection control unit 72 determines that at least one of two distances between adjacent coin gaps s in three consecutive coin gaps s is smaller than a predetermined thickness reference value, and the first coin gap When the distance between s and the third coin gap s is within a predetermined thickness reference range, the central coin gap s of the three consecutive coin gaps s is replaced with the coin gap s between the coins c. Therefore, it is possible to eliminate the influence of the scratches on the outer peripheral surface of the coin.

  Moreover, the excess / deficiency detection control unit 72 sets the number obtained by adding 1 to the number of the coin gaps s between the coins c as the accumulated coin detected number, and compares the accumulated coin detected number with a predetermined packaging reference number. Thus, in order to determine whether or not the number of coins of the accumulated coin C is excessive or insufficient, compared to the case of determining whether or not the number of coins is excessive or insufficient from the total length of the accumulated coins C, the effects of deformation and wear accumulate. Thus, it is possible to more accurately determine whether the number of coins is excessive or insufficient.

  Further, since the excess / deficiency detection control unit 72 determines the presence / absence of a different denomination as an abnormality from the output signal value of the magnetic sensor 70 between the coin gaps s, it is possible to detect mixing of different denominations. .

  Further, the excess / deficiency detection control unit 72 determines that the denomination is different when the output signal value of the magnetic sensor 70 between the coin gaps s is out of the denomination reference range to be accumulated. The inclusion of denomination can be detected.

  In addition, the excess / deficiency detection control unit 72 determines that the denomination is different when the difference between adjacent output signal values of the magnetic sensor 70 between the coin gaps s is outside a predetermined reference range. It is possible to properly detect the mixing of different denominations.

  In addition, the excess / deficiency detection control unit 72 detects the inclusion of deformed coins (folded coins) from the movement distance information of the magnetic sensor 70 during the detection of one coin gap s. can do. If the moving distance of the magnetic sensor 70 during the detection of one coin gap s is long, the total length of the accumulated coins C is also long. Therefore, if the number is appropriate and the total length is longer than the reference total length, it is determined that deformed coins are mixed. You may do it.

  Further, since the excess / deficiency detection control unit 72 warns when an abnormality consisting of at least one of excess / deficiency in the number of accumulated coins, mixing of deformed coins and mixing of different denomination coins is detected, Can be overlooked.

  In the above embodiment, the case where the presence or absence of the number of stacked sheets is determined by detecting with the magnetic sensor 70 the stacked coins C before winding the wrapping paper 45 will be described as an example. However, the presence / absence of the number of stacked sheets may be determined by detecting the wrapping coin 45 after winding the wrapping paper 45 with the magnetic sensor 70. However, the detection without the wrapping paper 45 can bring the magnetic sensor 70 closer to the peripheral surface of the accumulated coin C and the detection accuracy is increased, so that the accumulated coin C before the wrapping paper 45 is wound is used. On the other hand, the detection is preferably performed by the magnetic sensor 70.

  In the above embodiment, the case where the magnetic sensor 70 is moved with respect to the accumulated coins C in the immobile state has been described as an example. However, the magnetic sensor 70 is fixed in position and the accumulated coins C are moved in the accumulation direction. Thus, the output signal of the magnetic sensor 70 may be obtained.
