  By the way, in the coin processor, a plurality of endlessly stretched belts are provided on a pair of rollers, and the most upstream portion of the downstream belt is disposed below the most downstream portion of the upstream belt. We were carrying coins. Each belt requires a certain conveyance length, and as a result, it is difficult to reduce the size of the entire apparatus.

  An object of this invention is to provide the coin conveying apparatus which can achieve size reduction of a coin processing machine in view of the said situation.

  In order to achieve the above object, a coin transport device according to the present invention is applied to a coin processing machine that stores received coins for each denomination and dispenses coins stored according to a withdrawal instruction. A rail part constituting a conveyance path for conveying coins and a holding part capable of holding coins one by one are connected in an endless manner and displaced in one direction along the rail part. When the deposited coins are inserted into the transport unit and the transport unit that transports the deposited coins from below to above, the transport unit is opposite to the one direction. Control means for displacing in a reverse direction for a predetermined time and displacing the transport unit in the one direction after the lapse of the predetermined time is provided.

  In the coin transport device according to the present invention, the control unit may displace the transport unit in such a manner that the driving force for displacement in one direction is relatively smaller than the driving force for displacement in the reverse direction. Features.

  According to the present invention, a transport unit configured by endlessly connecting holding units capable of holding coins one by one is unidirectionally along a rail unit that configures a transport path for transporting coins. Since the coins deposited by displacing are transported from below to above, compared to conventional methods of transporting coins by providing a plurality of belts stretched endlessly on a pair of rollers, It is possible to reduce the installation area of the applied coin processor, and this brings about an effect that the coin processor can be downsized.

  In addition, when the coins inserted into the transport unit are inserted, the control unit displaces the transport unit in a direction opposite to the one direction for a predetermined time, and after the predetermined time has passed, the control unit moves in the one direction. Since the transport unit is displaced, it is possible to store the inserted coins and to receive more coins.

In such a rotating body 42, a plurality of (four in the illustrated example) coin passage holes 42a are formed on the same circumference around the central axis.

  A gear 44a of the driving force transmission unit 44 is engaged with the side surface of the rotating body 42 through the driving force applying opening 41c. As shown in FIG. 4, the driving force transmission unit 44 is interposed between the front conveying pulley 21 b and the rotating body 42 and transmits the rotational driving force of the conveying pulley 21 to the rotating body 42. .

  As described above, since the front-side transport pulley 21b is a driven pulley that rotates in accordance with the rotation of the rear-side transport pulley 21a, the rotational driving force of the rotating body 42 is given by the check transport motor 21c. That is, the rotation of the rotating body 42 and the rotation of the conveying pulley 21 are given from a common drive source, and the rotation of the rotating body 42 and the displacement of the conveying belt 22 are synchronized.

  The separation lid 43 is installed in such a manner as to cover the rotating body storage portion 41 a of the separation main body 41. The separation lid 43 is provided with an introduction port 43a and a movable flapper 45.

It is provided so as to be swingable around the central axis 45a. More specifically, as shown in FIG. 14, the movable flapper 45 is provided so as to be able to swing with a part of the tip of the movable action portion 45 b in contact with the upper surface of the rotating body 42.

  As shown in FIG. 3 and FIG. 4, the discrimination unit 50 is installed at a location on the rear side of the coin coin separation unit 40 and on the front side of the delivery port 24a. The discrimination unit 50 discriminates the authenticity and denomination of the coin when the coin conveyed backward by the coin coin conveyance unit 20 passes through a predetermined discrimination area. The discrimination unit 50 gives the discrimination result to the coin change control unit 60 as a discrimination signal. Furthermore, as shown in FIG. 15, the discrimination unit 50 is provided with a plurality of ball pressures 51. These ball pressures 51 are for pressing coins passing rearward from above.

  The check control unit 60 controls the operation of the coin check device 10a in accordance with programs and data stored in the memory 61. The quarantine control unit 60, for example, causes a processing device such as a CPU (Central Processing Unit) to execute a program, that is, may be realized by software or realized by hardware such as an IC (Integrated Circuit). Alternatively, software and hardware may be used in combination.

  In the coin check device 10a having the above-described configuration, a plurality of coins are deposited through the deposit unit 2, and the coin control unit 200 controls the operation of the coin processor 1 from the coin processing main control unit 200. When the operation command is given to 60, the change control unit 60 gives a drive command to the change transport motor 21c.

  As a result, the coin transportation motor 21c is driven, and in the coin coin transportation section 20, the transportation pulley 21 rotates counterclockwise as viewed from the left, whereby the transportation belt 22 is displaced along the extending direction. Further, due to the rotation of the transport pulley 21, the rotating body 42 of the coin separation unit 40 rotates in the clockwise direction through the driving force transmission unit 44 as viewed from above.

  Then, when the coins deposited by the depositing unit 2 are introduced into the upper surface of the rotating body 42 through the introduction port 43a of the separation lid 43, the coin checking unit 40 separates these coins into the respective coin passage holes 42a. Guidance in the state of lying down. As described above, since the movable flapper 45 is swingably provided on the separation lid 43 with a part of the tip portion of the movable action portion 45b being in contact with the upper surface of the rotating body 42, the movable flapper 45 is provided. The movable action portion 45b presses the coin on the upper surface of the rotating body 42, and guides the coin to the coin passage hole 42a in a sideways posture. Thereby, the coins guided to the coin passage hole 42a are stacked in the coin passage hole 42a.

  Of the coins guided and stacked in the coin passage hole 42 a, the lowest coin comes into sliding contact with the bottom surface portion 41 a 1 of the rotating body storage portion 41 a in the separation main body portion 41 by the rotation of the rotating body 42. And since the guide protrusion 41a2 is formed in the bottom face part 41a1 of the rotary body storage part 41a, as shown in FIG. 13, the coin change coin separating part 40 has the lowest position in contact with the guide protrusion 41a2. The coin is separated from the coin passage hole 42a and supplied to the coin-conveying coin transport unit 20 through the supply port 41b. That is, the coin coin separating unit 40 sends out the coins deposited through the depositing unit 2 in a state where the coins are separated one by one into the coin coin transporting unit 20.

  Coins supplied from the supply port 41b to the coin coin transport unit 20 are placed on the upper surface of the transport base 26 in a sideways posture. Since the conveyor belt 22 is displaced in the extending direction as described above, the pressing and conveying member 23 fixed to the conveyor belt 22 is placed on the upper surface of the conveyor base 26 as shown in FIG. The coin is pressed backward to convey the coin backward.

  Here, since the surface 23c facing the downstream side in the displacement direction of the transport belt 22 is V-shaped, the surface 23c facing the downstream side of the press transport member 23 is the transport belt 22 as shown in FIG. It becomes a surface which presses a coin from this displacement, and can be conveyed toward the back in a state where the coin is brought close to the central portion in the left-right direction.

  In this way, the coin is conveyed backward while being pressed by the pressure conveying member 23. When the conveyed coin reaches the discrimination region by the discrimination unit 50, the discrimination unit 50 determines whether the coin is true or false. Species distinguish. The discrimination unit 50 sends the discrimination result to the quarantine control unit 60 as a discrimination signal.

  The coin change control unit 60 inputs a discrimination signal from the discrimination unit 50, and gives a drive command to the sending flapper drive mechanism 24b when the discrimination result is a true coin. Thereby, the delivery flapper drive mechanism 24b is driven, and the delivery flapper 24 swings in the opening direction to open the delivery outlet 24a. When the delivery flapper 24 opens the delivery port 24a in this way, the coins that are conveyed backward through the discrimination region while being pressed by the pressure conveying member 23 abut on the guide member 30 and change the posture. , It passes through the outlet 24a and is sent to the coin transport device 10b. After the coins identified as genuine coins pass through the outlet 24a, the check control unit 60 gives a drive stop command to the delivery flapper drive mechanism 24b. As a result, the delivery port 24a is closed by the delivery flapper 24.

  On the other hand, the quarantine control unit 60 receives the discrimination signal from the discrimination unit 50, and when the discrimination result is a false coin, the sending control by the sending flapper 24 without giving a driving command to the sending flapper driving mechanism 24b. The closing of the outlet 24a is maintained.

  As a result, the coins that pass through the discrimination area and are conveyed backward while being pressed by the pressing and conveying member 23 pass through the upper surface of the delivery flapper 24, pass through the false coin opening 25, and fall downward. The coins that have dropped down in this way are placed in a sideways posture on the bottom of the transport apparatus body 20a.

  By the way, due to the rotation of the transport pulley 21, the lower part of the transport belt 22 is displaced forward. Therefore, as shown in FIG. 7, the pressing and conveying member 23 fixed to the conveying belt 22 moves forward below the coin coin conveying unit 20, so that the coins placed on the bottom are It can convey in the state which the press conveyance member 23 pressed toward the front. At this time, since the surface 23c facing the downstream side in the displacement direction of the conveyor belt 22 is V-shaped, the pressing and conveying member 23 conveys the coin toward the rear in a state where the coin is brought to the central portion in the left-right direction. can do.

  In this way, the coin coin transport unit 20 sends the coins (fake coins) transported forward to the payout unit 3 (see FIG. 4).

  The payout unit 3 includes a payout belt 3b stretched endlessly between a pair of left and right payout pulleys 3a. The payout unit 3 is configured such that the right payout pulley 3a is rotated by the drive of the payout motor 3c so that the payout coins are sent to the payout unit 4 and the coins provided in the payout unit 4 are provided. It is to be paid out from the payout opening 4a.

  As described above, the coin checking device 10a discriminates the authenticity and denomination of the coins deposited through the depositing unit 2, and sends the coins identified as genuine coins to the coin transport device 10b, Coins identified as fake coins are paid out to the outside through the withdrawal unit 4.

  And according to such a coin check apparatus 10a, the check coin conveyance part 20 is made to pass the fake coin opening 25 about the coin conveyed to back and discriminated from the fake coin by the discrimination part 50. Since it is conveyed forward, the length in the front-rear direction of the coin coin transport unit 20 can be shortened, whereby the coin processor 1 can be reduced in size.

  According to the coin coin checking device 10a, the pressing and conveying member 23 that constitutes the coin checking and conveying unit 20 has a V-shaped surface 23c that presses the coin by the displacement of the conveying belt 22. The coins can be transported in a state of being moved toward the central portion in the left-right direction, whereby the coins can be stably transported in a state where the transport position of the coins is restricted, and the accuracy of discrimination by the discrimination unit 50 is improved. Can be achieved.

Here, the thickness in the front-rear direction of the posture regulating action portion 101 b is set to a size capable of entering the second concave portion 82 c of the holding pressing member 82 and the fourth concave portion 83 c of the holding regulating member 83.

  As shown in FIG. 29, the posture regulating member 101 presses the coins conveyed upward by the curved upper extending portion 73a of the third rail forming member 73 toward the third rail forming member 73 (rail portion 70). By doing so, the posture of the coin is regulated.

  As shown in FIG. 26, the passage restricting member 102 is opposed to a continuous portion of the curved lower extending portion 71 a of the first rail forming member 71 and the first left extending portion 72 a of the second rail forming member 72. The second support plate 77 is provided. As shown in FIG. 30, the passage restricting member 102 is configured by integrally forming a passage restricting shaft portion 102a and a passage restricting action portion 102b.

  The passage restricting shaft portion 102a is a columnar member extending along the front-rear direction, and both end portions thereof are pivotally supported by the second support plate 77 so as to be swingable around the central axis of the passage restricting shaft portion 102a. Yes. Two passage restriction action portions 102b are provided in a pair of front and rear, and are separated from each other from the central region portion of the passage restriction shaft portion 102a toward the outside in the radial direction of the passage restriction shaft portion 102a. It is an extended part.

  The passage restricting member 102 is urged rightward by a passage restricting spring 102c that is an urging means, and the leading end portion of the passage restricting action portion 102b is placed in a passage area B of a coin conveyed by the conveying portion 80. Have entered the market.

  Such a passage regulating member 102 moves the first rail forming member 71 downward as shown in FIG. 31 when the conveyance unit 80 is displaced in one direction when the conveyance drive motor 83 is driven in the forward direction. The coin is allowed to pass by abutting against the coin conveyed toward the left and swinging leftward against the urging force of the passage restriction spring 102c.

  On the other hand, when the conveyance drive motor 83 is driven in the reverse direction and the conveyance unit 80 is displaced in the reverse direction, the passage restricting member 102 has the conveyance unit in the second rail forming member 72 as shown in FIG. The coins conveyed in the reverse direction by 80 are separated from the holding portion 81, and the passage of the coins through the curved extending portion 71 a of the first rail forming member 71 is restricted.

  The determination unit 110 is provided on the fourth rail forming member 74. The discriminating unit 110 discriminates the denomination of coins that are conveyed while being pressed by the holding pressing member 82 of the holding unit 81 in a predetermined discrimination region in the fourth rail forming member 74. The discrimination result at the discrimination unit 110 is output to the transport control unit 140 as a discrimination signal.

  The return unit 120 is provided on the downstream side of the determination unit 110 (determination region) in the transport path HK formed by the fourth rail forming member 74 and includes a return opening 121 and a return gate 122.

  The return opening 121 is an opening having a size that allows passage of all denomination coins conveyed by the conveying unit 80, and communicates with the dispensing unit 4.

  The return gate 122 normally closes the return opening 121, and swings to open the return opening 121 when a return command is given.

  The sorting unit 130 is provided on the downstream side of the return unit 120 in the transport path HK formed by the fourth rail forming member 74. The distribution unit 130 includes a plurality of distribution passage ports 131 and a distribution gate 132.

  Each of the plurality of sorting passage openings 131 is an opening having a size sufficient to allow coins to pass therethrough. The sorting gates 132 are provided so as to cross the transport path HK formed by the fourth rail forming member 74 corresponding to each sorting passage port 131. More specifically, the sorting gate 132 is configured by attaching a plurality of sorting gate action pieces 132b to the tip of a long cylindrical sorting gate shaft portion 132a, and the sorting gate shaft portion 132a. Is supported so as to be rotatable around the central axis of the shaft.

  Then, as shown in an enlarged view in FIG. 33, a locking claw portion 134 attached to the distal end portion of the plunger 133 is locked to the proximal end portion of the sorting gate shaft portion 132a. Here, when the sorting drive solenoid 135 is in a non-energized state, the plunger 133 causes the sorting gate action piece 132b to carry a coin as shown in FIG. 34 by the biasing force of the spring 136 attached thereto. The posture is taken away from the route HK.

  On the other hand, when the distribution drive solenoid 135 is energized when a drive command is given from the conveyance control unit 140, the plunger 133 is pulled by the distribution drive solenoid 135, and as shown in FIG. The distribution gate 132 is rotated around the central axis of the distribution gate shaft portion 132a, and the distribution gate action piece 132b is advanced to the transport path HK.

  When the sorting gate action piece 132b advances into the transport path HK in this way, as shown in FIG. 36, the end of the sort gate action piece 132b moves toward the sorting passage port 131 toward the downstream side in the carrying direction. An inclined portion K that is inclined in the direction is formed, and the coins conveyed along the conveying path HK by the inclined portion K can be guided to a predetermined sorting passage port 131.

  The conveyance control unit 140 comprehensively controls the operation of the coin conveyance device 10b according to programs and data stored in the memory 141. For example, the transport control unit 140 may cause a processing device such as a CPU (Central Processing Unit) to execute a program, that is, may be realized by software, or may be realized by hardware such as an IC (Integrated Circuit). Alternatively, software and hardware may be used in combination.

  Further, as described above, the transport control unit 140 gives a drive command to the transport drive motor 83 to drive the transport drive motor 83 in the forward rotation direction or the reverse rotation direction. When driving in the rolling direction, PWM control is performed so as to approximate a predetermined conveying force.

  On the other hand, when driving the conveyance drive motor 83 in the reverse direction, the conveyance control unit 140 controls the conveyance force to be larger than the conveyance force when driving in the forward direction.

  That is, the conveyance control unit 140 displaces the conveyance unit 80 in such a manner that the driving force for displacement in one direction is relatively smaller than the driving force for displacement in the reverse direction.

  In the coin transport device 10b having the above-described configuration, a coin discriminated as a genuine coin is sent from the coin check device 10a and an operation command is given from the coin processing main control unit 200 to the transport control unit 140. It works as follows.

  That is, the conveyance control unit 140 gives a drive command in the reverse direction to the conveyance drive motor 83 to drive the conveyance drive motor 83 in the reverse direction, and displaces the conveyance unit 80 in the reverse direction for a predetermined time. Thereby, the coins thrown into the second rail regulating member from the slot 72d are transported in the reverse direction by the transport unit 80 in the second rail forming member 72.

  By the way, the passage restricting member 102 causes the second rail forming member 72 to disengage the coins conveyed in the reverse direction by the conveying unit 80 from the holding unit 81, and the coins are bent downwardly extending 71 a of the first rail forming member 71. The coins inserted from the insertion port 72d can be stored in the second rail forming member 72.

  Then, after a predetermined time has elapsed, the conveyance control unit 140 gives a drive command in the forward rotation direction to the conveyance drive motor 83 to drive the conveyance drive motor 83 in the forward rotation direction, and causes the conveyance unit 80 to be Displace in the direction. Thereby, the coin stored by the 2nd rail formation member 72 can be conveyed in one direction along the conveyance path | route HK.

  Since the holding portion 81 of the conveying portion 80 has an inclined surface 82d formed on the pressing surface 82a of the bottom portion of the first concave portion 82b of the holding pressing member 82, the curved upward extending portion 73a of the third rail forming member 73 is formed. When passing, the inclined surface 82d is moved away from the rail by being displaced with the rail convex portion 73A of the third rail forming member 73 entering the first concave portion 82b.

  Therefore, even when two coins are overlapped in the lower region of the reverse roller 90 and are conveyed while being pressed by the holding and pressing member 82, as shown in FIG. 37, the coins are held using the inclined surface 82d. It can be detached from the pressing member 82. As a result, it is possible to suppress the occurrence of transport clogging or the like due to two coins being sandwiched between the reverse roller 90 and the transport unit 80.

  Further, in the upper region of the reverse roller 90, the posture regulating member 101 directs the coins conveyed upward by the curved upward extending portion 73a of the third rail forming member 73 toward the third rail forming member 73 (rail portion 70). Since the posture of the coin is restricted by pressing, it is possible to prevent the coin from being separated during the passage through the curved upper extension 73a.

  Furthermore, the upper end portion 73a1 of the curved upper extending portion 73a of the third rail forming member 73 and the right end portion 74a1 of the second left extending portion 74a of the fourth rail forming member 74 are opposed to each other and pass through this portion. In the holding portion 81, the rail convex portion 73A of the third rail forming member 73 enters the first concave portion 82b of the holding pressing member 82, and the fourth rail forming member 74 of the fourth rail forming member 74 enters the second concave portion 82c of the holding pressing member 82. Since the rail convex portion 74A enters the state, the coin pressed by the holding pressing member 82 is also sandwiched between the upper end portion 73a1 of the curved upper extension portion 73a and the right end portion 74a1 of the second left extension portion 74a. There is no possibility that the coins are separated from the transport path HK.

  In this way, in the holding portion 81 that has passed through the third rail forming member 73, one coin is held. And since the pressing surface 82a of the holding | maintenance press member 82 which comprises each holding | maintenance part 81 of the conveyance part 80 is comprised, it can convey stably in the state which brought the coin to the outer side of the conveyance path | route HK. it can.

  As described above, in the transport unit 80, the holding unit 81 that passes through the second rail forming member 72 and the holding unit 81 that passes through the fourth rail forming member 74 are vertically inverted, so that the first When the rail convex portion 74A of the fourth rail forming member 74 is displaced into the second concave portion 82c, the inclined surface 82d is positioned below the upper end portion of the rail convex portion 74A as shown in FIG. That is, the holding and pressing member 82 can reliably press the coin and stably convey it.

  Then, when the denomination of the coin passing through the determination area is determined by the determination unit 110, the transfer control unit 140 gives a drive command to the corresponding distribution drive solenoid 135 in accordance with the determination result, so The minute drive solenoid 135 is energized. As a result, the corresponding sorting gate 132 is rotated around the central axis of the sorting gate shaft portion 132a, and the sorting gate action piece 132b is advanced to the transport path HK. The coins can be guided to the corresponding sorting passage port 131 and stored in the coin storage unit 5 by the inclined portion K formed by the sorting gate action piece 132b.

  By the way, when the denomination of the coin is not determined by the determination unit 110, the transport control unit 140 does not give a drive command to any of the sorting drive solenoids 135. In that case, since all the sorting gates 132 are in a state in which the sorting gate action piece 132b is detached from the transport path HK, the coin that has passed through the fourth rail forming member 74 passes through the first rail forming member 71 as it is. After that, the second rail forming member 72 is reached, the passage of the transport path HK described above is repeated, and the determination unit 110 determines again.

  In this way, when all the coins transported along the transport path HK are stored in the coin storage unit 5 for each denomination within the operation time determined in advance, the transport control unit 140 causes the transport drive motor 83 to A drive stop command is given to stop the transport drive motor 83, and then a signal to the effect that the transport of coins is completed is sent to the coin processing main control unit 200.

  On the other hand, when the operation time has elapsed with coins remaining in the transport path HK, the transport control unit 140 gives a return command to the return gate 122 to open the return opening 121, and the transport path The coin carrying the HK is guided to the return opening 121 and sent to the withdrawal unit 4, and is paid out to the outside from the withdrawal unit 4.

  As described above, according to the coin transport device 10b, the transport unit 80 configured by connecting the holding units 81 capable of holding coins one by one in an endless manner is curved upward. By moving in one direction along a rail portion 70 that constitutes a predetermined transport path HK having a curved upper extending portion 73a (ascending portion) that extends in the direction, the received coins are transported from below to above. Therefore, the installation area of the coin processor 1 can be reduced as compared with the case where a plurality of belts stretched endlessly on a pair of rollers is provided as in the prior art, and the coin handling machine 1 is reduced. The processor 1 can be downsized.

  And the attitude | position control member 101 presses the coin conveyed upward in the curved upward extension part 73a of the 3rd rail formation member 73 toward the 3rd rail formation member 73 (rail part 70), and this coin Since the posture is restricted, it is possible to prevent the coins from being separated during the passage through the curved upper extending portion 73a, thereby suppressing the occurrence of coin clogging during the conveyance.

  Further, according to the coin transport device 10b, when the coin is inserted into the transport unit 80, the transport control unit 140 displaces the transport unit 80 in the reverse direction for a predetermined time, and after the predetermined time has elapsed. Since the transport unit 80 is displaced in the one direction, the coins inserted from the insertion port 72d can be stored in the second rail forming member 72, and more coins can be received from the coin check device 10a.

  Furthermore, according to the coin transport apparatus 10b, the transport control unit 140 displaces the transport unit 80 in such a manner that the driving force for displacement in one direction is relatively smaller than the driving force for displacement in the reverse direction. When a trouble occurs when a coin is transported in one direction along the transport path HK and a coin clogging occurs, the transport drive motor 83 is driven in the reverse direction to displace the transport unit 80 in the reverse direction. In addition, the release force of the coin jam can be made larger than the force when the coin is jammed, and the coin jam can be eliminated.

  Furthermore, according to the coin transport device 10b, the fourth rail forming member 74 can swing in the vertical direction about the central axis of the first protrusion 75a and the second protrusion 75b. When coin clogging occurs in the second rail forming member 72 or the like, the fourth rail forming member 74 is swung upward to easily remove the coin causing the coin clogging from the second rail forming member 72. it can.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications can be made.

  In the above-described embodiment, the check control unit 60 and the conveyance control unit 140 are configured separately. However, in the present invention, the same may be configured together with the coin processing main control unit 200. .

  Although not particularly described in the above-described embodiment, in the present invention, the curved portion from the second left extension 74a to the rear extension 74b of the fourth rail forming member 74, or the second extension 74b to the second extension. In the curved portion extending to the right extending portion 74c, the protruding height may be gradually reduced as the rail convex portion 74A goes outward. According to this, the coin to pass can be brought out to the outer side of the conveyance path | route HK.

  Further, in the present invention, a coin is formed on the curved portion from the first left extending portion 72a to the front extending portion 72b of the second rail forming member 72 or the outer portion of the curved portion from the front extending portion 72b to the first right extending portion 72c. You may provide the space for saving.
