Description

  The present invention relates to a coin processing apparatus in which a feeding unit that feeds coins put on a rotating disk one by one and a sorting unit that takes in the fed coins and sorts the coins are connected by a coin passage.

  A conventional coin processing device is cut into a plurality of U-shapes on the outer periphery in an inclined housing having a fake coin passage hole formed by a simple hole and a genuine coin passage hole provided with a lid for opening and closing. A metal rotating disk provided with a coin receiving part is arranged, a plurality of coins thrown into the lower part of the housing are picked up one by one by the coin containing part and conveyed to the coin discriminating means, and the coin discriminating means Authentic coins are discriminated, and genuine coins are transported and dropped into a normally open coin passage hole, and false coins are passed over the lid after closing the genuine coin passage hole. The coins that are transported to the holes and dropped from the counterfeit coin passage holes are selected (see, for example, Patent Document 1).

  However, in the technique of Patent Document 1, since a plurality of coins thrown into the lower part of the housing are picked up and conveyed one by one by the coin accommodating part, if the coin is caught at the corner of the rotating coin accommodating part. Then, the coins jump up and are not accommodated in the coin accommodating part, so that an empty coin accommodating part is formed, and there is a problem that the certainty in the conveyance of the coin is insufficient, and as a result, the processing efficiency of the coin is lowered.

  In order to improve the certainty of coin conveyance in the sorting unit and improve the processing efficiency in the coin sorting process, the applicant, in Japanese Patent Application No. 2009-264102, placed the coin processing device in a horizontally arranged feeding housing. Are arranged in a sorting housing which is arranged horizontally, and a feeding unit having a feeding rotary disc arranged on the feeding rotary disc, a separation gate for separating and feeding coins put on the feeding spinning disc one by one. A transport disk in which a plurality of coin storage portions partitioned by a spacing portion are formed at the periphery, a carry-in port through which coins carried into the coin storage portion pass, a disk rotation motor that drives the transport disk to rotate intermittently; A sorting unit that is arranged on the transport path of the coins stored in the coin storage unit and has an identification sensor for identifying the coins to be transported, and a separation unit of the feeding unit. A coin passage that is horizontally arranged to connect between the transport port and the entrance of the sorting unit and an upstream side of the coin passage in the direction of carrying in the coin at the entrance. Consists of a pair of transport rollers that wait at the standby position, and when the coin storage portion of the transport disk is stopped at the coin loading position facing the carry-in port, the transport roller pair is rotated to wait at the standby position The coins in the coin storage unit are transferred to the coin storage unit, and the coins in the coin storage unit are identified by the identification sensor consisting of a magnetic sensor during conveyance by intermittent rotation drive. The reject coin falls to the reject port, and the normal coin falls to the normal coin discharge port. A technique of sorting coins is proposed (see paragraphs 0012-0043 and 0086-0089 of the specification of the application, FIG. 2).

Further, the light emitting unit 40a and the light receiving unit 40b have been described as being arranged in the radial direction of the transport disk 13 in the center of the transport direction of the stopped coin storage unit 16, but any position that satisfies the above conditions Also good.
Further, the coin confirmation sensor 40 has been described as a sensor that detects the coin C at two detection positions with a pair of sensors, but two pairs of optical sensors are disposed at the positions of the light emitting unit 40a and the light receiving unit 40b, respectively. And you may make it detect the coin C in two detection positions.

In FIG. 5, 51 is a control part of a coin processing apparatus, and has the function etc. which control each part in a coin processing apparatus, and perform a coin sorting process etc.
A storage unit 52 stores a program executed by the control unit 51, various data used for the program, a processing result by the control unit 51, and the like.

Below, the coin selection process by the coin processing apparatus of a present Example is demonstrated.
The control unit 51 of the coin processing device detects the coins C that are input in a batch by the input detection sensor (not shown) of the input unit 7, and when those coins C fall on the supply rotary disk 3, The driving of the feeding rotating disk 3 is started and the driving of the conveying roller pair 27 by the conveying motor 29 is started.

When the feeding rotary disk 3 rotates in the feeding direction, the coins C received on the feeding rotary disk 3 abut against the inner peripheral surface of the side wall 2b of the feeding housing 2 by the centrifugal force caused by the rotation, and guide the inner peripheral surface of the side wall 2b. It is carried as a surface in the direction of the separation gate 8, separated into one by the separation gate 8 and fed to the coin passage 26, and the first coin C fed out is pushed by the succeeding coin C while passing through the coin passage 26. Move in the direction of pair 27.
When the coin C is separated, the lower surface of the opening of the separation gate 8 of the present embodiment is set slightly lower than the upper surface of the feeding rotary disk 3, so that the coin C does not get caught during separation and feeding smoothly. It is paid out.

  The coin C that has reached the pair of transport rollers 27 is sandwiched between the first transport roller 27a and the second transport roller 27b, and when the standby detection sensor 31 detects the coin C, the control unit 51 includes a transport motor. The driving of the transport roller pair 27 by 29 is stopped, and the transport roller pair 27 is made to wait at a specified standby position with the coin C held between the transport roller pair 27. The succeeding coins of the clamped coin C come into contact with the clamped coin C and stay at that position.

  On the other hand, the control unit 51 starts driving the transport disk 13 by the disk rotation motor 15 simultaneously with the start of driving of the transport roller pair 27 and the like, and the disk rotation motor 15 is driven for a predetermined drive time T1 (one pitch of the coin storage unit 16). After the drive, the predetermined stop time T2 is stopped, and the intermittent drive for intermittently rotating the transport disk 13 at a constant period is continued until the end of the process.

  The control unit 51 that has started the intermittent drive of the transport disk 13 waits for the position detection sensor 22 to detect the slit 21a of the positioning member 21 that rotates integrally with the transport disk 13, and the position detection sensor 22 performs the slitting. When 21a is detected (OFF), the drive by the disk rotating motor 15 is stopped after a predetermined time for correcting the phase shift between the slit 21a of the positioning member 21 and the coin accommodating portion 16, and the detected slit 21a is handled. The coin storage unit 16 is stopped at the coin carry-in position where the entrance of the coin storage unit 16 faces the carry-in port 18.

The control unit 51 that has stopped the coin storage unit 16 at the coin carry-in position resumes the coin C, which is sandwiched between the transport roller pair 27 and waited at the standby position, in the carry-in direction A by restarting the drive of the transport roller pair 27. It is conveyed and carried into the coin storage unit 16 from the carry-in entrance 18.
When the carry-in detection sensor 24 detects the loaded coin C and a predetermined stop time T2 elapses, the control unit 51 resumes the intermittent drive of the transport disk 13.
When the coin C is carried in, the bottom surface of the sorting housing 12 of the present embodiment is set slightly lower than the bottom surface of the coin passage 26, so that the coin C is smoothly carried in without being caught during the carry-in. .

In addition, since the carry-in direction A of the coin C according to the present embodiment is set so as to be shifted from the rotation center of the carrying disk 13 to the front side in the carrying direction, the coin C to be carried in enters obliquely with respect to the coin storage unit 16. This makes it possible to smoothly enter the coin C to be carried in, prevent the transfer disk 13 from being stopped due to the coin being caught between the carry-in entrance 18 and the entrance of the coin storage portion 16, and maintenance. Generation of work can be suppressed.
By repeating the above operation, the delivery of the coins C from the feeding unit 1 to the sorting unit 11 through the coin passage 26 is continuously executed.

  On the other hand, in the sorting unit 11, when the coin C accommodated in the coin accommodating part 16 passes through each identification sensor 34 of the identification part 33 by intermittent conveyance, various characteristic values of the coin are intermittently transmitted. Acquired by one identification sensor 34 per conveyance, and identifies the authenticity or denomination of the coin using the acquired values of the three identification sensors 34. If the identification result of the coin C is a reject coin, When the coin accommodating portion 16 that accommodates the reject coin stops on the reject port 36, the reject port opening / closing shutter 36a is opened, and the reject coin is dropped and discharged to the reject port 36 by its own weight, and the reject port is opened / closed. The rejection opening 36 is closed by closing the shutter 36a.

  And if the coin accommodating part 16 which accommodated the reject coin stops in the position where the coin confirmation sensor 40 is arrange | positioned, the control part 51 will determine the presence or absence of the coin C by the output from the coin confirmation sensor 40, and will light-emit. When the light receiving unit 40b receives light from the unit 40a and recognizes that the coin C is not present, it is determined that the reject coin has been discharged from the reject port 36, and the intermittent drive of the transport disk 13 is continued. Further, when the coin C remains in the coin storage unit 16 for some reason and the light from the light emitting unit 40a is blocked by the coin C and the light receiving unit 40b does not detect the light, the coin C is present. Then, it is determined that there is an abnormality, and the coin processing device is stopped.

  In addition, when the identification result by the identification unit 33 is a normal coin identified as a genuine coin, the coin that passes through the reject opening / closing shutter 36a regardless of the denomination and accommodates the normal coin after the passage. When the storage unit 16 stops at the position where the coin confirmation sensor 40 is disposed, the control unit 51 determines whether or not the coin C exists based on the output from the coin confirmation sensor 40, and when the coin C exists in the coin storage unit 16. Then, the normal coin is intermittently driven to convey the normal coin to the normal coin discharge port 38, and when the coin storage portion 16 stops on the normal coin discharge port 38, the normal weight of the coin C moves to the normal coin discharge port 38. Drop and discharge. Moreover, when the coin C does not exist in the coin accommodating part 16 by some factors (for example, erroneous fall of the normal coin to the rejection port 36, etc.), it determines with it being abnormal and stops a coin processing apparatus.

The same applies when the positions of the normal coin discharge port 38 and the reject port 36 are interchanged. In short, when the coin confirmation sensor 40 detects the presence or absence of the coin C, if the presence or absence of the coin is different from the state that should be originally, it is determined as abnormal.
In this way, the coin sorting process for the coins C fed from the feeding unit 1 is executed, and one coin C is sorted for each pitch of the coin storage unit 16.

  As described above, in this embodiment, the separation gate 8 of the feeding unit 1 that separates and feeds the coins C placed on the feeding disk 3 arranged horizontally is fed to the outer peripheral edge. The coin C accommodated in the plurality of coin accommodating portions 16 is horizontally disposed between the coin inlet 18 of the sorting unit 11 having the conveying disk 13 that conveys the coin C horizontally while intermittently rotating at a constant period. A pair of transport rollers 27 that are connected by the coin passage 26 and hold the coin C that is carried immediately before the carry-in entrance 18 of the coin passage 26 and waits at the standby position are provided. When stopped at the coin carry-in position, the transport roller pair 27 is rotated and the standby coins waiting at the standby position are carried into the coin storage unit 16, so that the coin C can be reliably carried into the coin storage unit 16. As well as coins Of shortening the loading time can be set shorter stop time T2 of the transfer disc in the intermittent driving of the constant period, it is possible to improve the processing efficiency in the coin sorting process.

  Further, the conveyance disc 13 which is intermittently driven by disposing the coin confirmation sensor 40 at the position of the coin accommodating portion 16 stopped between the reject port 36 and the normal coin discharge port 38 of the conveyance disc 13 stopped at the coin carry-in position. When at least one of the two detection positions arranged in the radial direction is detected during detection of the coin C, the presence of the coin C in the coin storage unit 16 is detected, so that it is stored in the coin storage unit 16. All types of coins C can be detected, and erroneous detection due to detection of the separation portion 17 of the transport disk 13 can be prevented, and coin detection accuracy can be improved.

  As described above, in this embodiment, the sorting unit having the reject port and the normal coin discharge port arranged on the downstream side in the transport direction of the identification unit has the reject port of the transport disk stopped at the coin loading position. A coin confirmation sensor that detects a coin at two detection positions is provided at a position of a coin storage section stopped between the normal coin discharge port, and at least one detection position is a coin storage section. The coins received in the coin storage unit are arranged side by side in the radial direction so as to detect the coins, and when the transport disk is stopped, the presence / absence of the coins stored in the coin storage unit is detected by the coin confirmation sensor. It is possible to detect all types of coins stored in the coin storage unit stopped downstream of the mouth, and prevent false detection by detecting the separation part of the transport disk. Te can coin to the reject outlet is reliably detect whether or not dropped.

  In the above embodiment, it has been described that the presence or absence of the coin C is detected by the coin confirmation sensor while the transport disk is stopped. However, the detection may be performed while the transport disk is being driven. In this case, the presence / absence of the coin C may be detected while confirming that the coin accommodating portion is passing the coin confirmation sensor based on the output from the position detection sensor.
