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).

JP-A-8-229513 (paragraph 0006-paragraph 0007, FIG. 1)

  However, since the technology of the above-mentioned Japanese Patent Application No. 2009-264102 can reliably carry coins into the coin storage part, the coin carry-in time can be shortened and the transport disk stop time in intermittent rotation drive can be shortened. Although it is a useful technique for improving the processing efficiency in the coin sorting process, the coin storage part of the transfer disk is sized to accommodate coins of the maximum diameter in order to enable the transfer of coins of different diameters. When a coin is identified by an identification sensor during the conveyance of a coin, a coin having a minimum diameter may pass through the identification sensor while moving irregularly by an inertial force or the like due to intermittent rotation drive in the coin accommodating portion. The characteristic value for identifying the coin detected by the sensor, especially the detected value of the diameter of the coin may vary, and the selected coin may be misjudged. There is a problem.

  In addition, since the diameter of the coin is detected by the magnetic sensor, in the case of coins of the same material (100-yen and 50-yen bronze coins in Japanese coins), the magnetic data acquired at the center of the passing coins If the diameter of the coin is detected by the capacity, the detected value approximates, and there is a problem that it may be difficult to determine the denomination based on the detected diameter.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide means for accurately detecting the diameter of a coin while stabilizing the behavior of the coin at the time of coin identification in the sorting unit. .

  In order to solve the above-mentioned problems, the present invention provides a transport disk which is disposed in a horizontally arranged sorting housing and has a plurality of coin storage portions formed by partitioning portions on an outer peripheral edge portion, and the coins. A carry-in port through which coins carried into the storage unit pass, a disk drive source that intermittently drives the transfer disk, and a transfer path of the coins stored in the coin storage unit are transferred by the intermittent rotation drive. In a coin processing apparatus comprising a sorting unit having a diameter detection sensor for detecting the diameter of a coin therein, a positioning lever is provided for aligning coins passing through the diameter detection sensor on the bottom surface of the coin housing part, The diameter detection sensor is configured to detect an end portion on an opposite side including an opposite end of the bottom surface of a coin positioned on the bottom surface by the positioning lever.

  Thus, the present invention can stabilize the behavior of the coin C passing through the diameter detection sensor, and can detect an enlarged area difference based on the diameter difference of the coin C. The effect that detection accuracy can be improved is obtained.

  Further, the identification sensor 41a (diameter detection sensor) of the present embodiment partially partially only the opposite end including the movement locus of the opposite end 42 of the coin C conveyed while being aligned by the alignment lever 36. Since it is arranged to detect, compared with the case where the magnetic capacity of only the central portion of the coin C is acquired, the area difference based on the diameter difference of the coin C passing through the identification sensor 41a can be enlarged. It is possible to detect the diameter of the coin C with high accuracy by increasing the change due to the difference in diameter of the magnetic capacity to be acquired.

Below, the selection operation | movement of the coin C by the coin processing apparatus of a present Example is demonstrated.
When a plurality of coins C put into the feeding unit 7 are dropped onto the feeding rotary disk 3, the feeding motor 5 starts to drive the feeding rotary disk 3 in the feeding rotation direction and is carried by the carry motor 29. Driving of the roller pair 27 and driving of the transport disk 13 by the disk rotation motor 15 are started.

  When the feeding rotary disc 3 rotates in the feeding rotational direction, the coin C received on the feeding rotary disc 3 comes into contact with the inner peripheral surface of the side wall 2b of the feeding housing 2 by the centrifugal force caused by the rotation, and the inner peripheral surface of the side wall 2b is contacted. It is conveyed as a guide 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 fed coin C is conveyed by the coin passage 26 while being pushed by the subsequent coin C. It moves in the direction of the roller pair 27.

  When the standby detection sensor 31 detects that the coin C reaching the transport roller pair 27 while being pushed by the subsequent coin is sandwiched between the transport roller pair 27, the drive of the transport roller pair 27 by the transport motor 29 is stopped, and the coin C is held at a specified standby position while being held between the conveying roller pair 27.

At this time, the transport disk 13 of the sorting unit 11 is rotated by a disk rotation motor 15 at a fixed period for stopping a predetermined stop time after being driven for a predetermined drive time (rotation time for one pitch of the coin storage unit 16). It is driven by intermittent rotation drive that repeatedly stops.
This intermittent rotation drive is triggered when the position detection sensor 22 detects the slit 21a of the positioning member 21 that rotates integrally with the transport disk 13, that is, when the position detection sensor 22 changes from ON to OFF. Is stopped at the coin loading position opposite to the carry-in port 18 and is driven again for a predetermined drive time after the elapse of a predetermined stop time until the end of the sorting operation of all the coins C input. Continued for a while.

When the coin storage unit 16 of the transport disk 13 stops at the coin carry-in position, the transport motor 29 rotates, and the coin C that is sandwiched between the transport roller pair 27 and stopped at the standby position is transferred from the carry-in entrance 18 to the coin storage unit 16. The coin C that has been carried in and carried in by the carry-in detection sensor 24 is detected (ON).
And after progress of predetermined stop time, the conveyance disk 13 starts rotation again, and the coin C accommodated in the coin accommodating part 16 in the coin carrying-in position is shown in FIG. Along with the rotation, the sorting housing abuts against the inner peripheral surface of the side wall 12b of the sorting housing 12 by the centrifugal force due to the rotation, and is pushed along the inner peripheral surface of the side wall 12b while being pushed by the separation portion 17 on the rear side in the conveyance rotation direction. It is conveyed in the direction of the identification unit 40 on the 12 bottom plates 12a. In addition, the coin C shown in FIG. 6 is the coin C of the minimum diameter.

  When the coin C accommodated in the coin accommodating portion 16 is conveyed to the positioning lever 36, the coin C is urged in a direction to rotate toward the center side of the conveying disk 13 and the side wall of the sorting housing 12. As shown in FIG. 6B, the positioning lever 36 that is stopped by being stopped by a biasing force on a stopper (not shown) is brought into contact with the positioning lever 36 protruding into the sorting housing 12 from the notch 38b. As shown in FIG. 6C, the outer diameter of the coin C is indicated by a two-dot chain line in FIG. Before reaching the diameter detection sensor, it contacts the bottom surface 16a.

After contact with the bottom surface 16a, the coin C spreads the positioning lever 36 outwardly in the radial direction around the rotation fulcrum 37 against the urging force of the positioning lever 36, as shown in FIG. 6 (d). However, it is sandwiched between the positioning lever 36 and the bottom surface 16a of the coin storage part 16 and conveyed in a state of alignment, and passes through the identification sensor 41a.
At this time, the identification sensor 41a detects the diameter of the coin C based on the magnetic characteristics based on the magnetic capacity and the material corresponding to the area of the opposite end of the passing coin C. Further, the alignment detection sensor 44 detects that the coin C passing through the identification sensor 41a is aligned with the bottom surface 16a formed of the arc surface of the coin storage unit 16.

When the outer surface of the coin C passes through the tip 36a of the positioning lever 36, the coin C again comes into contact with the inner peripheral surface of the side wall 12b of the sorting housing 12 by the centrifugal force generated by the rotation of the transport disk 13, and periodically rotates intermittently. It passes through the identification sensors 41b and 41c as it is driven.
The above-described coin C transported along the inner peripheral surface of the side wall 12b is once pressed against the bottom surface 16a of the coin accommodating portion 16 by the positioning lever 36, and is transported again along the inner peripheral surface of the side wall 12b. The movement trajectory of the coin C is referred to as a transport trajectory of the coin C in this embodiment.

  And when the coin C accommodated in the coin accommodating part 16 passes each identification sensor 41 of the identification part 40 by intermittent conveyance, the magnetic characteristic of the said coin C is one identification sensor 41 per conveyance by intermittent rotation drive. The authenticity and denomination of the coin C using the diameter and material of the coin C acquired by the identification sensor 41a and the characteristic values such as the thickness and presence / absence of holes by the other two identification sensors 41b and 41c. Are identified by the identification unit 40, and when the identification result is a reject coin, when the coin storage unit 16 storing the coin C stops on the reject port 33, the reject port opening / closing shutter 33a is opened. The reject coin falls to the reject port 33 due to its own weight, and after the drop, the reject port opening / closing shutter 33a is closed to close the reject port 33.

  Further, when the identification result by the identification unit 40 is a normal coin identified as a genuine coin, it is conveyed to the normal coin discharge port 34 through the reject opening / closing shutter 33a regardless of the denomination, and the normal coin is When the accommodated coin storage unit 16 stops on the normal coin discharge port 34, the coin C falls to the normal coin discharge port 34 by its own weight and is discharged.

  In this way, when the sorting operation is performed in which the coins C fed from the feeding unit 1 are sorted one by one for each pitch of the coin storage unit 16, and the sorting of all the inserted coins C is completed. The driving of the feeding rotary disk 3 by the feeding motor 5, the driving of the conveying roller pair 27 by the conveying motor 29, and the driving of the conveying disk 13 by the disk rotating motor 15 are stopped.

  As described above, in this embodiment, when the coin C is intermittently transported by the transport disk 13 and the diameter or the like of the coin C is detected by the identification sensor 41a of the recognition unit 40, the coin C is removed by the positioning lever 36. Since the bottom surface 16a of the coin accommodating part 16 is shifted and aligned, the behavior of the coin C can be stabilized when the identification sensor 41a passes, and the diameter detection accuracy by the identification sensor 41a can be improved.

  Also, the magnetic characteristics of only the opposite end including the movement trajectory of the opposite end 42 of the coin C through which the identification sensor 41a is aligned and passed by the positioning lever 36 to the bottom surface 16a made of the arcuate surface of the coin receiving portion 16 are provided. Therefore, the area difference based on the diameter difference of the coins C can be enlarged and detected, and the detection accuracy of the diameter by the identification sensor 41a can be further improved.

  Further, the bottom surface 16a of the coin accommodating portion 16 of the present embodiment is formed by an arc surface having a radius R2 with the rotation center of the transport disk 13 as the center, and the coin C is aligned to the bottom surface 16a by the alignment detection sensor 44. Compared to the case where the bottom surface 16a is a flat surface, the variation in area difference based on the diameter difference of the coin C passing through the identification sensor 41a is minimized, and the diameter of the coin C is increased with high accuracy. Can be detected.

In this embodiment, the identification sensors 41a, 41b, and 41c are described as being arranged in a pair in the upper and lower directions, but each identification sensor 41 may be arranged only in the upper side or only in the lower side.
Further, in this embodiment, the positioning detection sensor 44 is described as being disposed only below the transport disk 13, but the positioning detection sensor 44 may be disposed only above or in a pair of upper and lower.

  Further, in this embodiment, the positioning lever 36 is described as being provided only in the vicinity of the identification sensor 41a. However, the other two identification sensors 41b and 41c are similarly arranged at positions corresponding to the respective identification sensors 41. The positioning lever 36 may be provided.

  As described above, in this embodiment, the diameter detection sensor (identification sensor 41a) detects the diameter of the coin C while the coin C housed in the coin housing portion provided with the transport disk of the sorting housing is transported by intermittent rotation driving. ) And a coin handling device that identifies the coin C is provided with a positioning lever that positions the coin passing through the diameter detection sensor on the bottom surface of the coin storage unit, and the diameter detection sensor accommodates the coin with the positioning lever.
