Description

  The present invention relates to a coin depositing / dispensing device that stores coins by denomination and dispenses the coins stored therein, and a coin jamming for preventing coin jamming in a coin storing unit that may occur in the coin depositing / dispensing device. The present invention relates to a prevention member and a coin jam prevention method.

  In recent years, a coin deposit / withdrawal device is connected to a POS (Point Of Sales) terminal or ECR (Electronic Cash Register) for the purpose of reducing the work burden at the time of merchandise sales or enabling a quick transaction. A lot is happening.

  As is known in the art, this coin deposit / withdrawal device sorts coins inserted from a coin slot into denominations by a coin sorting unit, drops them into a coin storage unit, and stores them in a denomination in the coin storage unit. The coin is paid out to a coin payout exit based on a payout instruction (see Patent Document 1). In the coin storage unit, coins are placed on a coin payout belt provided for each denomination and are transported along with the rotation of the coin payout belt.

  Here, the coin payout belt that forms the bottom of the coin storage unit is disposed around the coin dropping position located below the coin sorting unit, and is inclined so as to increase from the position toward the downstream side in the coin transport direction. There are many. If the coin drop area is not in the low position, the coin falling and storing operation will be hindered, and at the coin payout position, the coin payout position will be placed at a high position due to the structure of dropping the coin to the coin payout outlet. It is. Due to such a structure, the coins in the coin storage portion are likely to gather around the coin dropping position.

  Moreover, in the exit position in a coin storage part, it is common to provide the separation mechanism which isolate | separates the lowest-order coin on a coin delivery belt from another coin. A reverse roller is often used for this separation mechanism. For this reason, the upper coins separated from the lowest coin on the coin payout belt by the reverse roller are returned to the coin drop position direction, so that the coins in the coin storage portion tend to gather around the coin drop position. Is encouraged.

  As a coin depositing / dispensing device, a device having a narrow housing width has recently appeared. In such a coin deposit / withdrawal apparatus, in order to narrow the housing width, the width of the coin storage part for each denomination is also narrowed, for example, a width that is a size obtained by adding a plus α to the diameter of the coin of the corresponding denomination (See Patent Document 2).

  However, when the width of the coin storage portion for each denomination is narrowed, there is a problem that coin clogging easily occurs in the coin storage portion. That is, as shown in FIG. 17, an upright coin CV may be sandwiched between the coin CP that is substantially parallel to the coin dispensing belt 201 and the side surface 203 of the coin storage unit 202. In such a case, the coins CP and CV are sandwiched between both side surfaces 203 of the coin storage portion 202, and coin clogging occurs.

  Such a problem is likely to occur frequently in 1-yen coins from the viewpoint of the denomination of coins. The reason is that a separation mechanism for separating coins one by one from the material of a one-yen coin called aluminum, for example, the coin surface is scraped by a reverse rotation operation of a reverse roller 204, and the scraped scrap is transferred to a conveyor belt. It is estimated that this is because the coin conveying force by the conveying belt 201 decreases due to adhesion to the 201.

  Also, the problem of coin jamming is that from the viewpoint of the position where coin jamming occurs, the lowest coin drop position in the coin storage unit, the separation mechanism for separating coins one by one, for example, the position near the reverse roller 204 This is particularly noticeable at the two locations. The reason why coin clogging is likely to occur at the coin drop position is that, as described above, the coins in the coin storage unit are likely to gather around the coin drop position. It is estimated that this is because the coin CV illustrated in FIG. Further, the reason why coin clogging is likely to occur near the reverse roller 204 is that the reverse roller 204 pushes back the coin with a certain amount of pushing back force, so that the pushed back coin is in an upright state like the coin CV illustrated in FIG. It is presumed that this is likely to occur.

  In addition, this applicant obtained patent documents 2-4 by search as technical literature which provides the solution considered to be effective with respect to the coin jamming in a coin storage part.

  An object of the present invention is to prevent coin clogging in a coin storage unit.

The present invention sorts coins inserted from a coin slot into denominations by a coin sorting unit and drops them into a coin storage unit, and transports coins stored in this coin storage unit by denomination based on a payout instruction. In the coin depositing / dispensing device, which is conveyed by a coin dispensing belt that is inclined so that the downstream side in the direction becomes higher, separated one by one by a separation mechanism and dispensed to a coin dispensing outlet, it is stored in a coin storage unit and used. and a stopper portion provided in the main body portion, said body portion has a embody the cylindrical basic figure rolling off by its own weight at low from high place in the coin storage portion, the stopper portion , wherein the coin dispensing belt is transported in the coin receiving portion upward without roll off the body, rolling the body portion reaching to said separation mechanism toward at low pushed back to the separating mechanism makes a successful That the degree of rolling resistance as the shape to be imparted to the body portion, the body portion shape than the main body portion on a part of the outer circumferential surface obtained by adding a small-diameter cylindrical shape, a part of the outer peripheral surface of the main body portion A coin jamming prevention member having any one of a protruding teardrop shape and a ridge shape obtained by cutting off a part of the outer peripheral surface of the main body is defined.
Another aspect of the present invention is that the coins inserted from the coin slot are sorted into denominations by the coin sorting unit and dropped into the coin storage unit, and the coins stored in the denomination are dispensed into the coin storage unit. In the coin depositing / dispensing device, which is conveyed by a coin dispensing belt that is inclined so that the downstream side in the coin conveying direction becomes higher based on the instructions, separated one by one by a separation mechanism, and dispensed to a coin dispensing outlet, the coin is accommodated in the coin accommodating unit. The main body and a stopper provided on the main body, and the main body is a polygonal column shape that embodies the basic form of rolling by its own weight from a high place to a low place in the coin storage part. The corner portion of the polygonal column shape formed by the main body portion is conveyed upward without rolling down the main body portion in the coin storage portion by the coin dispensing belt, and the main body portion reaching the separation mechanism is Separation The rolling resistance enough to be pushed back to the structure roll down toward the lower place a shape of the stopper portion to impart to the body portion, defining a coin clogging prevention member.

  The present invention defines the above-described coin depositing / dispensing apparatus in which such a coin jamming prevention member is stored in the coin storage unit.

  In the present invention, the above-described coin jamming prevention member is transported upward without rolling down due to the rolling resistance applied to the stopper portion in the coin storage portion by the coin payout belt, and the coin that has reached the separation mechanism A clogging prevention member is pushed back to the separation mechanism and falls over the rolling resistance provided by the stopper portion and rolls down toward a low place, and when coin clogging occurs in the coin storage portion, A coin clogging prevention method is defined in which coin clogging is released in association with repeated operations of the ascending process and the dropping process by the preventing member.

  According to the present invention, when coin clogging has occurred in the coin storage unit, the coin clogging prevention member has been moved upward in the coin storage unit by the coin payout belt and the coin clogging member reaching the separation mechanism is low. By repeating the dropping process that rolls down toward the place, the coins that have been clogged with the coin clogging preventing member are crushed, thereby preventing coin clogging in the coin storage unit.

  An embodiment of the present invention will be described with reference to FIGS.

[Basic configuration and operation]
FIG. 1 is a perspective view showing the overall appearance, and FIG. 2 is a plan view showing the internal structure.

  A coin insertion slot 2 that opens upward is provided in front of the right side of the main body case 1 as a casing. The coin slot 2 is provided with a plurality of sets of slot sensors 3 that optically detect the presence or absence of coins. Such a coin insertion slot 2 is provided with a coin introduction belt 4 that conveys the inserted coins toward the back, and is irregularly positioned on one end of the coin insertion slot 2 on the coin introduction belt 4. An insertion slot roller 5 is provided for sending out the inserted coins one by one.

  At the end portion of the coin introduction belt 4, a curved direction changing portion 6 that converts the coin conveyance direction to a right angle is arranged, and the coin whose direction of conveyance has been converted to a right angle by the direction changing portion 6 is conveyed to the coin sorting position. A coin sorting belt 7 is provided.

  Next, a sorting hole 8 for each denomination whose hole width dimension is sequentially increased along the coin sorting belt 7 is provided in the rear of the main body case 1, and a coin sorting portion 9 located at the coin sorting position is formed here. Yes. Six sorting holes 8 are provided so as to correspond to respective denominations of 1 yen, 50 yen, 5 yen, 100 yen, 10 yen, and 500 yen. The coin sorting unit 9 is provided with a counting sensor 10 for each sorting hole 8.

  FIG. 3 is a vertical side view of the coin storage unit, and FIG. 4 is a perspective view of the coin storage unit.

  Inside the main body case 1, there is provided an upper-opening coin storage portion 12 that communicates with each of the sorting holes 8 and is partitioned for each coin by a partition plate 11. A coin payout belt 13 is provided around a driving roller 14 and a driven roller 15 on the bottom surface portion of each coin type of the coin storage unit 12. The drive roller 14 is connected to and driven by a motor M described later via a drive mechanism 101 (see FIG. 16). Therefore, the coin payout belt 13 is rotationally driven using the motor M as a drive source.

  And the reverse roller 16 which isolate | separates a coin for every sheet is arrange | positioned at the exit of the coin storage part 12 so that the exit part of all the money types may be crossed. The reverse roller 16 is connected to a motor M, which will be described later, via a drive mechanism 101 (see FIG. 16), and rotates in the same direction as the rotation direction of the coin dispensing belt 13. Thereby, the reverse roller 16 fulfill | performs the function which isolate | separates the lowest coin on the coin delivery belt 13 from the upper coin conveyed by being laminated | stacked on it. Here, a separation mechanism 17 that separates coins stored in the coin storage unit 12 in denominations one by one when being dispensed is configured.

  Further, on the downstream side of the coin feeding belt 13 in the coin transport direction with respect to the reverse roller 16, a coin standby section 18 is provided for each denomination for aligning and waiting a predetermined number of coins in a line. The coin payout belt 13 extends to the coin standby unit 18 and reaches a coin payout position located in the front of the main body case 1. The coin standby unit 18 is provided with a coin shutter 19 whose operation is controlled so as to temporarily stop the coins and send out the required number of coins. The coin shutter 19 is driven and controlled by the dispensing solenoid 20 and pays out the designated coin and the number of coins by controlling the operation. Further, a payout sensor 21 is provided immediately after the payout solenoid 20.

  As shown in FIGS. 1 and 2, a coin payout outlet 22 is disposed at the end position of the coin payout belt 13. The coins transported to the coin payout belt 13 are paid out to the coin payout outlet 22 when the coin shutter 19 driven by the payout solenoid 20 opens.

  Here, as shown in FIG. 3, the coin payout belt 13 is inclined and arranged so that its height increases from the coin dropping position where the coin falls from the coin sorting unit 9 toward the downstream side in the coin transport direction. The inclination is arranged so as to continue to a position near the reverse roller 16. The coin payout belt 13 is maintained in a horizontal state from the position near the reverse roller 16 to the end position of the coin payout belt 13. In order to form such an arrangement state of the coin payout belt 13, a bending roller 23 for bending the coin payout belt 13 is arranged between the driving roller 14 and the driven roller 15. The reason why the coin payout belt 13 is inclined as described above is that if the coin drop region where the coin falls from the coin sorting unit 9 is not at a low position, the coin falling and storing operation is hindered. This is because it is desired to position the coin payout position at a high position due to the structure of dropping the coin to the payout opening 22 and paying it out.

  Next, an electrical hardware configuration of the coin deposit / withdrawal apparatus having such a configuration will be described with reference to FIG. FIG. 16 is a block diagram showing an electrical hardware configuration of the coin deposit / withdrawal apparatus.

  As shown in FIG. 16, the coin depositing / withdrawing apparatus according to the present embodiment includes a microcomputer 102 (hereinafter referred to as a microcomputer), and the microcomputer 102 drives and controls each unit. The microcomputer 102 is a ROM (Read Only Memory) that stores in advance fixed data such as a control program via a bus line 104 such as an address bus and a data bus in a CPU (Central Processing Unit) 103 that controls each part centrally. ) 105, a RAM (Random Access Memory) 106 for storing data in a rewritable manner, and a communication interface 107 are connected to each other.

  The control program stored in the ROM 105 enables drive control of each unit by the microcomputer 102. In this way, as each unit that is driven and controlled by the microcomputer 102, the coin depositing / dispensing device of the present embodiment includes an operation display unit 24 (see FIG. 1 for the appearance) connected to the microcomputer 102 via the bus line 104, and a motor M. A drive mechanism 101 as a drive source and a dispensing solenoid 20 are provided. Various sensors, that is, the input port sensor 3, the counting sensor 10, and the payout sensor 21 are also connected to the microcomputer 102 via the bus line 104, and the sensing results are transmitted to the microcomputer 102. Further, although an external configuration is not illustrated, a full sensor 25 for detecting that the coin is full in the upstream region is provided in the upstream region of the coin storage unit 12, and the full sensor 25 is also connected to the bus line 104. And the sensing result is transmitted to the microcomputer 102. The various sensors, that is, the insertion port sensor 3, the counting sensor 10, the dispensing sensor 21, and the full sensor 25 are transmissive optical sensors configured by a combination of a laser diode and a phototransistor.

  Next, the operation will be described.

  In the coin deposit / withdrawal apparatus according to the present embodiment, the CPU 103 uses the sensing results of various sensors, that is, the insertion port sensor 3, the counting sensor 10, the dispensing sensor 21, and the full sensor 25 in accordance with a control program stored in the ROM 105. On the other hand, by controlling the driving mechanism 101 and the dispensing solenoid 20, a coin-type deposit / withdrawal operation according to denomination is executed. At this time, the coin deposit / withdrawal apparatus performs various communications with a POS terminal / ECR (not shown) connected via the communication interface 107, and transmits necessary information to the POS terminal / ECR, etc. / Coin dispensing operation is executed in response to a command from ECR or the like.

  When a coin is inserted into the coin slot 2, the slot sensor 3 detects the coin and the coin introduction belt 4 is driven. Then, the inserted coins are fed one by one by the insertion slot roller 5 and the coin introduction belt 4 and conveyed, and the direction is changed at right angles by the direction changing unit 6 and conveyed to the coin sorting belt 7, and the coin sorting unit 9. The sorting by denomination is done. That is, it is dropped into the sorting hole 8 according to the denomination and stored in the coin storage unit 12. The number of coins dropped from the sorting hole 8 is counted by the counting sensor 10. When there is no coin in the coin standby unit 18, the coin payout belt 13 is driven and operation control is performed so that a predetermined number of coins always exist in the coin standby unit 18.

  On the other hand, when there is a payout command from the POS terminal / ECR or the like, the coin payout belt 13 is driven and the payout solenoid 20 is operated for each denomination to send out the required number of coins. It is paid out to the coin payout exit 22.

[Countermeasures against coin clogging]
In the present embodiment, the interval between the partition plates 11 that divides the coin storage portion 12 for each denomination, in other words, the width of the coin storage portion 12 for each denomination is equal to the diameter of the coin of the corresponding denomination. It is formed wider than the length obtained by adding the thickness of the minute, and narrower than the length obtained by adding the thickness of the two coins to the diameter of the coin of the corresponding denomination. And the coin storage part 12 corresponding to a certain denomination and the coin storage part 12 adjacent to this are partitioned by only one partition plate 11. Thereby, the coin depositing / withdrawing apparatus of the present embodiment has an extremely narrow casing width and realizes space saving.

  On the other hand, as already described with reference to FIG. 17, an upright state is established between the coin that is substantially parallel to the coin payout belt 13 and the partition plate 11 that forms the side surface of the coin storage portion 12. Coins may be pinched, and in such a case, these coins are pinched between the pair of partition plates 11 forming both side surfaces of the coin storage portion 12, and coin clogging occurs.

  For this reason, the coin deposit / withdrawal apparatus according to the present embodiment employs various coin jam prevention measures. The following introduces measures to prevent such coin clogging.

(1) Friction force of coin payout belt 13 against coins In this embodiment, a denomination made of aluminum, that is, friction in coins of coin payout belt 13 corresponding to a 1-yen coin in this embodiment. The force is set to be stronger than the friction force of the coin payout belt 13 corresponding to the other denomination against the coin (friction force setting means). As a technique for realizing this, in the present embodiment, the coin payout belt 13 corresponding to a denomination other than 1 yen is formed of rubber such as chloroprene as a material, but coin payout corresponding to 1 yen is used. The belt 13 is made of polyether urethane.

  FIG. 5 is a longitudinal sectional front view showing a cross-sectional shape of the coin dispensing belt 13. In FIG. 5, (a) shows the coin payout belt 13 corresponding to denominations other than 1 yen, and (b) shows the coin payout belt 13 corresponding to 1 yen. As is clear from FIG. 5 (a), the coin payout belt 13 corresponding to a denomination other than 1 yen is molded from rubber such as chloroprene for the purpose of maintaining the shape for the purpose of molding rubber such as chloroprene. A reinforcing member 13b made of nylon or the like is joined to the base portion 13a. The base portion 13a and the reinforcing member 13b are formed by heating and filling rubber such as chloroprene and nylon in a mold (not shown). For this reason, due to the difference in the thermal shrinkage rate between the two materials, as illustrated in FIG. On the other hand, since the coin payout belt 13 corresponding to 1 yen is formed using polyether urethane as a material, it can have a single material configuration of polyether urethane. Therefore, as illustrated in FIG. 5B, the warp that occurs in the coin payout belt 13 corresponding to a denomination other than 1 yen does not occur. As a result, regarding the joint area of the coin with respect to the coin payout belt 13, the coin payout belt 13 corresponding to a denomination other than 1 yen illustrated in FIG. 5A corresponds to 1 yen illustrated in FIG. 5B. The coin payout belt 13 has a larger coin bonding area. As a result, the frictional force with respect to the coin of the coin payout belt 13 corresponding to the one-yen coin is set stronger than the frictional force with respect to the coin of the coin payout belt 13 corresponding to other denominations.

  Here, it is preferable that the coin payout belt 13 corresponding to denominations other than 1 yen is made of rubber such as chloroprene as a material so as not to increase the frictional force between the coins excessively. If the frictional force between the coin payout belt 13 corresponding to a denomination other than 1 yen and the coin is too large, the coin is sandwiched between the coin payout belt 13 and the reverse roller 16 as the reverse roller 16 rotates. This is because such a phenomenon may occur and coin clogging may occur. On the other hand, since the 1-yen coin is made of aluminum, the weight is light, and even if the frictional force with the coin dispensing belt 13 becomes strong, the coin dispensing belt 13 and the reverse roller are accompanied by the rotation of the reverse roller 16. There is no such thing as being caught between

  Rather, in the case of a one-yen coin, as described above, the surface of the coin is scraped by the reverse rotation operation of the reverse roller 204, and the scraped scrap adheres to the coin dispensing belt 201 so that the coin conveying force by the coin dispensing belt 201 is increased. Therefore, coin clogging is more likely to occur as the frictional force with the coin dispensing belt 201 is weaker. On the other hand, in the present embodiment, since the coin payout belt 13 corresponding to 1 yen is made of polyether urethane, the friction force between the coin payout belt 13 and the 1 yen coin is strong. As a result, the coin payout belt 13 gives a sufficient conveying force to the one-yen coin. As a result, when coins in an upright state are sandwiched between the coins that are substantially parallel to the coin payout belt 13 and the partition plate 11 that forms the side surface of the coin storage portion 12, coin clogging is likely to occur. Since the coin payout belt 13 imparts a strong conveying force to the 1-yen coin, such coin clogging is suppressed.

  As already described, the problem of coin jamming is that, from the viewpoint of the position where coin jamming occurs, the lowest coin drop position in the coin storage unit 12 and the separation mechanism 17 that separates the coins one by one in this embodiment. This is particularly noticeable at two locations, in the vicinity of the reverse roller 16. The coin clogging prevention measure of the present embodiment in which the frictional force with respect to the coin of the coin dispensing belt 13 corresponding to the one-yen coin is set stronger than the frictional force with respect to the coin of the coin dispensing belt 13 corresponding to other denominations is as follows. It is effective at any point.

(2) Expanding part formed in the partition plate 11 FIG. 6 is a perspective view of the partition plate 11, and FIG. 7 is a front view of the coin storage unit 12.

  As shown in FIG. 6, an expansion portion 11 a that extends the interval between the pair of partition plates 11 is formed on one partition plate 11 that constitutes the coin storage portion 12 corresponding to one yen. As is clear from FIG. 7, the expanded portion 11 a is formed on the entire coin storage portion 12 such that the height from the coin payout belt 13 is lower than the diameter of 1 yen (h in FIG. 7). Crossing is formed. Moreover, the expansion part 11a is formed in the partition plate 11 on the opposite side to the coin storage part 12 for 50 yen adjacent to 1 yen, as shown in FIG. And in the position where the expansion part 11a was formed, the space | interval between a pair of partition plates 11, in other words, the width | variety of the coin storage part 12 corresponding to 1 yen is equivalent to the 1 yen diameter for the 2 sheets of 1 yen. It is formed wider than the length obtained by adding the thickness, and narrower than the length obtained by adding the thickness of three pieces per circle to the diameter of one circle.

  The expansion part 11a having the above configuration plays a role of suppressing coin jamming in the coin storage part 12. That is, the expanding portion 11a is formed so that the height from the coin payout belt 13 is lower than the diameter of one yen, so that the one-yen coin that is to stand upright at the position of the expanding portion 11a is vertically upright. Without being inclined. As a result, it becomes difficult for the coins to be caught between the coins that are in a state of being substantially parallel to the coin dispensing belt 13 and the partition plate 11 that forms the side surface of the coin storage unit 12, and the coins are jammed in the coin storage unit 12. Can be prevented.

  Here, in this Embodiment, the expansion part 11a is formed only in one side of the partition plate 11 corresponding to 1 yen. As described above, this corresponds to the fact that, in terms of the denomination of coins, coin clogging in the coin storage unit 12 is likely to occur frequently in Japanese yen one-yen coins.

  In addition, as shown in FIG. 7, the expanded portion 11a is formed on the partition plate 11 on the opposite side to the coin storage portion 12 for 50 yen adjacent to 1 yen. That is, the expansion part 11a is formed in the partition plate 11 which does not contribute to formation of the coin storage part 12 corresponding to another denomination. Thereby, by providing the expansion part 11a, the inconvenience which expands the width | variety of the whole coin storage part 12, and enlarges the housing | casing width | variety of a money depositing / withdrawing apparatus by extension will not arise.

  As already described, the problem of coin jamming is that, from the viewpoint of the position where coin jamming occurs, the lowest coin drop position in the coin storage unit 12 and the separation mechanism 17 that separates the coins one by one in this embodiment. This is particularly noticeable at two locations, in the vicinity of the reverse roller 16. The coin clogging prevention measure of the present embodiment in which the expanded portion 11 a is formed in the partition plate 11 is particularly effective at the lowest coin drop position in the coin storage portion 12.

(3) Mirror Surface Processing of Partition Plate 11 FIG. 8 is a schematic view illustrating mirror surface processing applied to the partition plate 11.

  The surface of the partition plate 11 on which coins contact is in a state where sharp roughness is scattered in various places as illustrated in FIG. On the other hand, mirror finishing, for example, buffing, is performed up to the portion indicated by the solid line a in FIG. Then, as shown in FIG.8 (c), the sharp roughness scattered on the surface which the coin contacts in the partition plate 11 becomes flat, and resistance between the coin which slides and moves on the surface of the partition plate 11 is achieved. Decrease. As a result, when coins in an upright state are sandwiched between the coins that are substantially parallel to the coin payout belt 13 and the partition plate 11 that forms the side surface of the coin storage portion 12, coin clogging is likely to occur. Since the partition plate 11 reduces the frictional resistance against the coin, such coin clogging is suppressed.

  As already described, the problem of coin jamming is that, from the viewpoint of the position where coin jamming occurs, the lowest coin drop position in the coin storage unit 12 and the separation mechanism 17 that separates the coins one by one in this embodiment. This is particularly noticeable at two locations, in the vicinity of the reverse roller 16. The coin clogging prevention measure of the present embodiment in which the surface of the partition plate 11 on which coins come into contact is mirror-finished is effective at any location.

  Here, in this Embodiment, the partition plate 11 which performs mirror surface processing assumes the partition plate 11 corresponding to all the denominations. On the other hand, even if mirror finishing is performed only on the part of the partition plate 11 where the expanded portion 11a is formed, particularly in the vicinity of the reverse roller 16, it is possible to provide an extremely effective coin clogging prevention measure. That is, when the expanded portion 11a is formed, coin clogging is suppressed for the reason described above. However, in the vicinity of the reverse roller 16, many coins are stacked on the coin dispensing belt 13, so the stacked coins narrow the space of the expanded portion 11 a, and coin clogging occurs in the narrowed space of the expanded portion 11 a. May end up. On the other hand, if mirror finishing is applied to the location where the enlarged portion 11a of the partition plate 11 is formed in the vicinity of the reverse roller 16, the space between the partition plate 11 and the coin that slides on the surface thereof is provided. The resistance is reduced, and it becomes possible to make it difficult to cause coin clogging in the narrow space of the expanded portion 11a.

(4) Coin jam prevention member FIG. 9 is a perspective view of a coin jam prevention member, and FIG. 10 is an exploded perspective view thereof.

  The coin jam prevention member 51 has a main body 52 and a stopper 53 provided on the main body 52. The main body portion 52 and the stopper portion 53 are constituted by two cylindrical members having the same height and greatly different diameters, and are joined so that their outer peripheral surfaces are in contact with each other. As a structure for that purpose, the large-diameter main body 52 has a mounting hole 54 drilled from a part of its outer peripheral surface so as to pass through the central portion, and a pair of base holes that come out to the outer peripheral surface on the opposite side. The screw insertion hole 55 is formed. The small diameter stopper portion 53 has a pair of screw holes 56 formed on the outer peripheral surface thereof. The formation interval between the pair of screw insertion holes 55 formed in the main body portion 52 and the formation interval between the pair of screw holes 56 formed in the stopper portion 53 are formed to coincide with each other. Therefore, a pair of screws 57 are inserted into the screw insertion holes 55 from the attachment holes 54 formed in the main body 52, and these screws 57 are screwed into the pair of screw holes 56 formed in the stopper portion 53 and tightened. Thus, the main body portion 52 and the stopper portion 53 are joined so as to bring the outer peripheral surfaces into contact with each other, and the coin jamming prevention member 51 is configured.

  Here, the large-diameter columnar shape in the main body portion 52 embodies a basic form of rolling down from a high place to a low place in the coin storage portion 12 by its own weight. Further, the shape of the small-diameter columnar shape in the stopper portion 53 is conveyed upward in the coin storage portion 12 without rolling down in the coin storage portion 12 as the coin payout belt 13 rotates, and the reverse roller 16 constituting the separation mechanism 17. The main body 52 that has reached this point is pushed back by the reverse roller 16 to realize a shape that gives the main body 52 a rolling resistance to the extent that it rolls down toward a low place. In that sense, the main body portion 52 and the stopper portion 53 are not limited to the shapes illustrated in FIGS. 10 and 11, and various shapes can be employed. FIGS. 11 to 13 individually illustrate the various shapes of the main body 52 and the stopper 53. That is, FIG. 11 illustrates a tear-type coin jamming prevention member 51 in which a part of the outer peripheral surface of the cylindrical stopper portion 53 protrudes smoothly to become the stopper portion 53. A columnar stopper 53 is partly cut off in the axial direction to form a stopper-shaped coin clogging prevention member 51. The example illustrated in FIG. 13 is a polygonal shape whose corners serve as the stopper 53. This is a coin jam prevention member 51.

  As the height of the coin jam prevention member 51 illustrated in FIGS. 9 to 13, that is, the length in the axial direction, when the coin jam prevention member 51 is stored in the coin storage unit 12 for each denomination, the coin for each denomination It is desirable that the thickness of the corresponding denomination of three coins plus α, or four plus α is between the pair of partition plates 11 forming the storage portion 12.

  FIG. 14 is a vertical side view of the coin storage portion 12 for explaining the raising operation of the coin jam prevention member 51, and FIG. 15 is a vertical side view of the coin storage portion 12 for explaining the fall operation of the coin jam prevention member 51. is there. As shown in FIGS. 14 and 15, the coin jamming prevention member 51 is stored in the coin storage unit 12 and used. In this case, the coin jamming prevention member 51 may be accommodated in the coin storage unit 12 of all denominations. However, in this embodiment, the coin jamming prevention member 51 is accommodated only in the coin storage unit 12 corresponding to 1 yen. An example of using As described above, this corresponds to the fact that, in terms of the denomination of coins, coin clogging in the coin storage unit 12 is likely to occur frequently in Japanese yen one-yen coins.

  When the coin payout belt 13 rotates in a state in which the coin jamming prevention member 51 is accommodated in the coin storage portion 12 corresponding to 1 yen, the coin jamming prevention member 51 is conveyed upward in the coin storage portion 12 along with the rotation operation. (Rising process). This is because the main body 52 that is about to fall due to its own weight is conveyed upward without rolling down due to the rolling resistance applied to the stopper 53. This state is illustrated in FIG.

  Next, the coin jam prevention member 51 reaching the reverse roller 16 is pushed back to the reverse roller 16 and rolls down toward a low place exceeding the rolling resistance provided by the stopper portion 53 (dropping process). This state is illustrated in FIG.

  In the example shown in FIG. 14, coin clogging occurs near the reverse roller 16 and above the coin payout belt 13. In such a case, coins that are clogged with coins are collapsed by the coin clogging prevention member 51 and the coin clogging is released as the coin clogging prevention member 51 repeats the ascending process and the dropping process. Although not shown, as long as it is a coin jam occurring on the movement trajectory of the coin jam prevention member 51 in the coin storage part 12, such a coin jam is a repetition of the ascending process and the dropping process by the coin jam prevention member 51. It will be surely broken with the movement, and the coin jam will be released.

  As already described, the problem of coin jamming is that, from the viewpoint of the position where coin jamming occurs, the lowest coin drop position in the coin storage unit 12 and the separation mechanism 17 that separates the coins one by one in this embodiment. This is particularly noticeable at two locations, in the vicinity of the reverse roller 16. The coin clogging prevention measure of the present embodiment in which coins that are clogged with coins are repelled in accordance with the repetitive operations of the ascending process and the dropping process by the coin clogging prevention member 51 is effective at any location.
