Description

  The present invention relates to a coin processing machine.

In a coin processing machine, when a plurality of coins are inserted, they are generally separated one by one and fed out and conveyed to perform a predetermined process. As a device for separating and feeding out such coins, it has a rotating disk into which a plurality of coins are inserted, and a separation ring that forms a regulating gap for one coin between the rotating disks and rotates. When the disk rotates, the passage of the coins fed out by the centrifugal force is controlled so that it does not overlap two or more in the separation ring, and the coins are separated and fed out one by one from the rotating disk, leading to the conveyance path for subsequent processing, Some are transported by a feed unit provided on the transport path. And there is also a technique that applies this technique, and further devise to reliably separate and feed out coins one by one in an optimal state (for example, see Patent Document 1).
Japanese Utility Model Publication No. 62-146268

  However, even if the above-described technology is used, if the coins to be inserted into the rotating disk are curved and deformed, or if foreign objects such as clips are mixed in the coins, the separation ring described above is used when the coins are fed out. It is inevitable that the regulation gap between the rotating disk and the rotating disk will be clogged with coins or foreign matter, causing the rotating disk to lock up and cause an abnormal device condition. And, when recovering from the abnormal state of the device, remove the coins or foreign matter clogged in the regulation gap between the separation ring and the rotating disk, which is the cause of the abnormality, or remove the coins remaining in the subsequent transport path There is a need. At that time, the operator opens the separation ring or opens the feed unit, but it is rare to forget to close the feed unit after removal, but often forgets to close the separation ring. It was. The reason for this is that the separation ring is smaller in size and smaller in opening and closing angle than the feed unit due to its characteristics, so it is difficult to notice forgetting to close, and the separation ring is opened and closed less frequently than the feed unit. It is estimated that there are things.

  Then, if the operator proceeds with the abnormality recovery process in a state where the operator has forgotten to close the separation ring, when the rotating disk is rotated by the initial operation in the reset process, the coins remaining in the rotating disk are There are secondary obstacles such as being scattered out of the transport path and scattered, or it is drawn out to the transport path in a state where multiple coins overlap, and coins are clogged in the transport path or further subsequent parts. Will occur. For this reason, it is conceivable to provide an open / close detection sensor for detecting forgetting to close the separation ring, but in this case, the cost increases.

  Therefore, an object of the present invention is to provide a coin processing machine that can prevent forgetting to close the sorting ring while suppressing an increase in cost.

In order to achieve the above object, the invention according to claim 1 includes a rotating disk, a separation ring that is openable and closable and that restricts passage of coins fed from the rotating disk in a closed state one by one, and the separation ring. In a coin processing machine comprising: a conveyance path that guides coins that have passed through; and a feed unit that is provided on the upper side of the conveyance path so as to be openable and closable and that conveys coins on the conveyance path in a closed state. conjunction with have a forced closing mechanism for the separating ring closed, forcible closing mechanism, the separation ring in the open state, to the closed state by the pressing force at the time of closing operation of the feed unit Features.

  The invention according to claim 2 is the invention according to claim 1, wherein the separation ring and the feed unit are supported by a horizontal shaft provided in the machine body so as to be swingable in the vertical direction, and the forced closing mechanism is A locked portion provided in the separation ring; a support member provided adjacent to the separation ring; and a horizontal axis of the support member supported so as to be swingable at a position above the locked portion. A separation ring lock lever and a lock pin provided on the feed unit. When the separation ring lock lever is swung in one direction, the separation ring lock lever is contacted with the engaged portion of the separation ring on the upper side. A regulating surface that contacts and regulates the upward movement of the locked portion and closes the separation ring, and when swung in the opposite direction, is lifted from the locked portion of the closed separation ring A release surface that releases the restriction on the upward movement of the locked portion and is pressed from above To form a pressed surface that swings the sorting ring lock lever in the one direction, and the lock pin causes the pressing surface of the sorting ring lock lever to be moved from above by closing the feed unit. The separation ring lock lever is pressed to swing in the one direction.

  According to a third aspect of the present invention, in the second aspect of the present invention, the separation ring lock lever is formed with a slit that restricts the swing range to a predetermined range by contacting the restriction portion of the support member. It is characterized by that.

  The invention according to claim 4 is the invention according to claim 2 or 3, wherein the restriction surface and the release surface of the separation ring lock lever are formed continuously, and the locked portion is rotatable. It is characterized by comprising a bearing.

  According to the first aspect of the invention, since the forced closing mechanism forcibly closes the separation ring in conjunction with the closing operation of the feed unit, the separation ring is always closed when the feed unit is closed. It becomes. Therefore, since it is not necessary to provide an open / close detection sensor for detecting forgetting to close the separation ring, it is possible to suppress an increase in cost and to prevent forgetting to close the separation ring.

  According to the second aspect of the present invention, when the feed unit is closed, the forcible closing mechanism is configured such that the lock pin provided in the feed unit presses the pressed surface of the separation ring lock lever from above and this separation ring. Swing the lock lever in one direction. Then, the restriction surface provided on the separation ring lock lever comes into contact with the locked portion of the separation ring on the upper side to restrict the upward movement of the locked portion, thereby closing the separation ring. On the other hand, when the separation ring lock lever is swung in the reverse direction, the release surface provided on the separation ring lock lever is spaced upward from the locked portion of the closed separation ring and The upward movement restriction is canceled, and the separation ring can be opened. As described above, the forced closing mechanism is relatively simple, in which a separable part is provided in the separation ring, a lock pin is provided in the feed unit, a support member is provided in the fuselage, and a separation ring lock lever is provided in the support member. Since the structure is simple, an increase in cost can be reliably suppressed.

  According to the invention of claim 3, since the swing range of the separation ring lock lever is restricted to a predetermined range by the slit and the restriction portion, the separation ring lock lever does not swing more than necessary, Unnecessary swing range can be eliminated.

  According to the fourth aspect of the present invention, the regulation surface and the release surface of the separation ring lock lever are formed continuously, and the locked portion is constituted by a rotatable bearing. Therefore, the regulating surface and the releasing surface are smoothly moved on the bearing. Therefore, the stress applied to the restriction surface and the release surface is reduced, and wear deterioration of each of the restriction surface, the release surface, and the locked portion can be prevented.

A coin processor of one embodiment of the present invention will be described below with reference to the drawings.
The coin processing machine 11 of this embodiment is to count and store rose coins inserted from outside the machine, classify them into denominations, and store them horizontally as shown in FIG. From the outer edge of the rotating disk 12 so as to block the disk 12, the substantially cylindrical side wall part 13 that rises vertically from the outer edge part of the rotating disk 12, and a notch part of the side wall part 13. It has a coin feeding part 15 which consists of a sorting ring 14 which rises vertically. Here, the side wall portion 13 is arranged so that there is no gap with respect to the rotating disk 12 so that the passage of coins is impossible, and the separation ring 14 is rotated so that the passage of one coin is possible. Between the disk 12, the clearance gap larger than the thickness of the thickest coin among the coins to handle and smaller than the thickness of two thinnest coins among the coins to be handled is formed.

  The loose coins inserted from the outside of the machine into an unillustrated slot of the coin processor 11 fall into the above-described coin feeding unit 15, and in this state, the rotating disk 12 rotates counterclockwise as shown in FIG. When rotated, the coins are carried along the inner peripheral surface of the side wall portion 13 by the centrifugal force, separated one by one through a gap with the sorting ring 14, and sequentially fed out from the coin feeding portion 15. That is, the sorting ring 14 restricts passage of coins fed out from the rotating disk 12 one by one.

  At the coin feeding position of the coin feeding section 15, a transport path 20 that guides the coins fed from the coin feeding section 15, that is, the coins that have passed through the sorting ring 14, and a feed unit 21 that transports the coins on the transport path 20. Is provided.

  The conveyance path 20 includes a first passage portion 23 disposed along a tangential direction of the rotating disk 12 and a second passage portion 24 extending in an orthogonal direction from the opposite side of the first passage portion 23 to the rotating disk 12.

And an overflow sorting unit 31 for dropping coins identified as “overflow sorting port 30”.

  The third passage portion 25 is provided with denomination selection ports 32a to 32f that can drop coins and guide the dropped coins to a denomination storage in the aircraft. These sorting ports 32a to 32f are designed to drop coins from those having a small outer diameter, and drop 1 yen, 50 yen, 5 yen, 100 yen, 10 yen, and 500 yen in order from the most upstream side. It is like that.

  The feed unit 21 includes a plurality of conveyor belts 35 for conveying the coins fed from the coin feeding unit 15 by pressing the coins against the conveyance path 20 from the upper side, and pulleys 36 for installing the conveyor belts 35. The coins fed out from the coin feeding unit 15 are conveyed by the driving force of the feed unit 21 while being guided by the conveyance path 20. During the conveyance by the feed unit 21 and the conveyance path 20, the coin is first identified by the identification unit 27. Then, the coin that could not be identified by the identifying unit 27 is dropped from the reject port 28 by the rejecting unit 29, and the coin that has been identified as an overflow denomination coin by the identifying unit 27 is subjected to overflow sorting. It will be dropped from the overflow sorting port 30 by the part 31, and other coins will fall from the corresponding ones of the sorting ports 32a to 32f of denomination.

  As shown in FIG. 2, a pedestal (supporting member) 40 that constitutes a part of the airframe is disposed at a position adjacent to the separation ring 14 in a fixed position. A moving support shaft (horizontal shaft) 41 is arranged. The above-mentioned feed unit 21 is supported on the swing support shaft 41 so as to be swingable up and down. As a result, the feed unit 21 can open the transport path 20 shown in FIG. As shown in FIG. 6, it is provided so as to be able to swing open and close. The feed unit 21 is closed as shown in FIG. 3 during the transfer of coins on the transfer path 20, and is opened as shown in FIG. 4 when the coins in the transfer path 20 are removed. State. Although not shown, the feed unit 21 has a lock mechanism that locks the feed unit 21 in a closed state, a release lever that unlocks the lock mechanism, and a swing operation handle that are opposite to the swing support shaft 41. On the side. Although not shown, the swing support shaft 41 is provided with a spring that urges the feed unit 21 so as not to return from the open state to the closed state due to its own weight. Further, although not shown, the feed unit 21 is provided with an open / close detection sensor for detecting the open state and the closed state.

  As shown in FIG. 2, the feed unit 21 is provided with a lock pin 42 that is parallel to the swing support shaft 41 so as to protrude in the direction of the separation ring 14, and the lock pin 42 is connected to the feed unit 21. Is rotated integrally with the feed unit 21, and as a result, pivots about the swing support shaft 41.

  On the above-described pedestal 40, a swinging support shaft (horizontal shaft) 44 extending in the direction of the rotary disk 12 in parallel with the swinging support shaft 41 is disposed at a fixed position. 44, the separation ring 14 is supported via an attachment plate 45 so as to be swingable up and down on one end side in the length direction (circumferential direction of the rotary disk 12). Thereby, the separation ring 14 is also provided so as to be able to swing and open so as to open a gap with the rotating disk 12. When the separation ring 14 is in the closed state shown in FIG. 3, a gap for restricting passage of coins one by one is formed between the separation ring 14 and the rotary disk 12. Further, the separation ring 14 is urged in the opening direction by an unillustrated spring provided at the position of the swing support shaft 41 so as to be in the open state shown in FIG.

  A support shaft 46 parallel to the swing support shaft 44 is fixed to the separation ring 14 at an intermediate position in the length direction away from the swing support shaft 44 by a predetermined distance. 47) is held rotatably. The bearing 47 moves integrally with the separation ring 14 when the separation ring 14 swings, and as a result, pivots about the swing support shaft 44.

  A swing support shaft (horizontal shaft) 50 is provided on the rotary disk 12 side of the seat 40 above the bearing 47 so as to be parallel to the swing support shaft 41. A sorting ring lock lever 51 is swingably supported on the shaft 50. The separation ring lock lever 51 is provided above the bearing 47 of the separation ring 14 together with the swing support shaft 50.

  The separation ring lock lever 51 includes an operation plate portion 53 supported by the swing support shaft 50 in a state orthogonal to the swing support shaft 50, and a swing support shaft 44 that supports the separation ring 14 of the operation plate portion 53. An operation plate portion 54 formed along the swing support shaft 44 is provided on the upper side. An arcuate slit 55 centering on the swing support shaft 50 is formed below the swing support shaft 50 of the operating plate portion 53, and the swing support from the seat 40 is formed in the slit 55. A restricting pin (restricting portion) 56 protruding in parallel with the shaft 50 is inserted. As the slit 55 abuts on the restriction pin 56 at each end, the swinging range of the separation ring lock lever 51 is restricted to a predetermined range.

  The separation ring lock lever 51 has a substantially V-shaped lower surface projecting downward, and switches the lower surface located above the bearing 47 by swinging.

  That is, as shown in FIG. 3 and FIG. 4, the separation ring lock lever 51 is swung in one direction and the end of the slit 55 opposite to the operation plate portion 54 is in contact with the restriction pin 56. Of the lower surface of the operating plate portion 53, the restricting surface 53A opposite to the operation plate portion 54 is positioned vertically above the bearing 47, contacts the bearing 47 on the upper side, and moves upward to the bearing 47. The movement is restricted and the separation ring 14 is closed. At this time, the operation surface 54A on the upper surface of the operation plate portion 54 is substantially horizontal. When the operation surface 54A of the operation plate 54 receives an operation input from the upper side, the separation ring lock lever 51 swings in the reverse direction.

  Further, as shown in FIG. 5, the separation ring lock lever 51 swings in the reverse direction, and the operating ring 53 of the separation ring lock lever 51 is in a state where the end of the slit 55 on the operation plate 54 side is in contact with the restriction pin 56. The release surface 53B on the operation plate portion 54 side of the lower surface is positioned vertically above the bearing 47, and is spaced upward from the bearing 47 of the separation ring 14 in the closed state to move upward to the bearing 47. Release movement restrictions. Actually, the separation ring 14 opens and follows the upward movement of the release surface 53B without the bearing 47 being separated from the release surface 53B by the spring bias. Here, the regulation surface 53A and the release surface 53B are continuously formed so as to be gently connected.

  The separation ring lock lever 51 has an upper surface opposite to the operation plate portion 54 disposed below the lock pin 42 of the feed unit 21, and the upper surface is formed by the lock pin 42 as shown in FIG. 6. When pressed from above, the separation ring lock lever 51 is caused to abut on the end opposite to the operation plate portion 54 of the slit 55 against the restriction pin 56, and to be pressed in the above-described one direction 53C. It has become.

  During the operation of the coin processor 11, both the separation ring 14 and the feed unit 21 are positioned at fixed positions. In this state, the lock pin 42 of the feed unit 21 comes into contact with the pressed surface 53C of the separation ring lock lever 51 and presses it downward, and the separation ring lock lever 51 swings in one direction as described above. In this state, the restricting surface 53A is in contact with the bearing 47 and presses it downward. At this time, since the lock pin 42 of the feed unit 21 is in contact with the separation ring lock lever 51, the swinging of the separation ring lock lever 51 and the separation ring 14 is restricted, and the separation ring 14 is closed. It is locked with.

  When an abnormality such as a coin jam occurs, the operator first operates a release lever (not shown) to unlock the feed unit 21 in the closed state by the lock mechanism, and is provided in the vicinity of the release lever. The swing operation handle (not shown) is lifted to open the feed unit 21 upward about the swing support shaft 41. Note that once the feed unit 21 is swung to the open state, the open state is maintained by a spring (not shown).

  When the feed unit 21 is opened upward, as shown in FIG. 4, the lock pin 42 of the feed unit 21 is separated from the pressed surface 53 </ b> C of the separation ring lock lever 51, and swings in one direction described above. The separation ring lock lever 51 in the state can be swung in the reverse direction described above. In this state, when the operator presses the operation surface 54A of the operation plate 54 downward, the separation ring lock lever 51 swings in the reverse direction around the swing support shaft 50 as shown in FIG. As a result, the release surface 53B is positioned vertically above the bearing 47, and moves upward from the position of the bearing 47 before the swing. Therefore, the bearing 47 can move, and the separation ring 14 swings upward about the swing support shaft 44 by a biasing force of a spring (not shown).

  Here, as an example of the factor that opens the feed unit 21, the occurrence of an abnormality such as a coin jam in the conveyance path 20 can be given as an example. In this case, once the feed unit 21 is opened as described above, the coins remaining on the transport path 20 are removed. Further, as an example of the factor that opens the separation ring 14, there is an abnormality in which the rotating operation of the rotating disk 12 is locked due to a foreign substance such as a coin or a clip that is curved and deformed in the gap between the separation ring 14 and the rotating disk 12. . In this case, in order to confirm the clearance between the separation ring 14 and the rotary disk 12 which is a direct cause of locking, the feed unit 21 is opened as described above, and then the separation ring 14 is opened as described above. The gap between the separation ring 14 and the rotating disk 12 is opened to remove the clogged deformed coins and foreign matters, and in addition to this, the coins remaining on the conveying path 20 are also removed.

  When an abnormality such as a coin jam is canceled, the operator closes the feed unit 21 against the biasing force of the spring. When the feed unit 21 is closed, the lock pin 42 of the feed unit 21 abuts against the pressed surface 53C of the separation ring lock lever 51 and presses it downward during the closing operation, as shown in FIG. The separation ring lock lever 51 swings in one direction as described above, and the vertical upper position of the bearing 47 of the release surface 53B gradually moves downward, and subsequently, as shown in FIG. The regulating surface 53A continuing to the surface 53B rides on the bearing 47 and pushes down the bearing 47, and locks the separation ring 14 in a closed state against the biasing force of a spring (not shown). Next, the operator locks the feed unit 21 in a closed state by a lock mechanism (not shown). When the closed state of the feed unit 21 is detected by an open / close detection sensor (not shown), it is detected that not only the feed unit 21 but also the separation ring 14 is closed.

  As described above, the bearing 47 provided in the separation ring 14, the seat 40 provided adjacent to the separation ring 14, and the swing support shaft 50 of the seat 40 are supported to be swingable at a position above the bearing 47. The separation ring lock lever 51 and the lock pin 42 provided on the feed unit 21 constitute a forced closing mechanism 60 that closes the separation ring 14 in conjunction with the closing operation of the feed unit 21.

  According to the coin processing machine 11 of the present embodiment described above, the forced closing mechanism 60 forcibly locks the separation ring 14 in the closed state in conjunction with the closing operation of the feed unit 21. In the closed state, the separation ring 14 is automatically locked in the closed state. Therefore, since it is not necessary to provide an open / close detection sensor for detecting forgetting to close the separation ring 14, it is possible to suppress an increase in cost and to prevent forgetting to close the separation ring 14.

  Specifically, when the feed unit 21 is closed, the forcible closing mechanism 60 causes the lock pin 42 provided in the feed unit 21 to press the pressed surface 53C of the separation ring lock lever 51 from above, and this separation ring. The lock lever 51 is swung in one direction. Then, the restriction surface 53A provided on the separation ring lock lever 51 abuts on the bearing 47 of the separation ring 14 on the upper side to restrict the upward movement of the bearing 47 and lock the separation ring 14 in the closed state. On the other hand, when the separation ring lock lever 51 is swung in the reverse direction, the release surface 53B provided on the separation ring lock lever 51 is separated upward from the bearing 47 of the closed separation ring 14 and above the bearing 47. Therefore, the separation ring 14 can be opened. As described above, the forced closing mechanism 60 is provided with the bearing 47 in the separation ring 14, the lock pin 42 in the feed unit 21, the seat 40 in the body, and the separation ring lock lever 51 in the seat 40. Since the structure is relatively simple, an increase in cost can be reliably suppressed.

  Further, since the swing range of the separation ring lock lever 51 is restricted to a predetermined range by the slit 55 and the restriction pin 56, the separation ring lock lever 51 is not swung more than necessary, and unnecessary swinging is performed. In addition to eliminating the range, the stroke of the operation surface 54A of the separation ring lock lever 51 is also the minimum necessary movable range, and the unlocking operation is facilitated.

  Further, since the regulation surface 53A and the release surface 53B of the separation ring lock lever 51 are formed continuously, and the separation ring 14 is in contact with these by a rotatable bearing 47, the separation ring lock lever 51 The restricting surface 53A and the release surface 53B move smoothly on the bearing 47. Therefore, the stress applied to the regulation surface 53A and the release surface 53B is reduced, and wear deterioration of each of the regulation surface 53A, the release surface 53B, and the bearing 47 can be prevented.

  In the above embodiment, the case where the feed unit 21 is swingably supported by the swing support shaft 41 provided at one end of the rotary disk 12 has been described as an example. Is also applicable to a case where the oscillating support is swingably supported by a swing support shaft provided at the other end on the side opposite to the rotating disk 12. That is, even if there is a difference in the position of the swing support shaft of the feed unit 21, the lock pin 42 can be brought into contact with the pressed surface 53 </ b> C of the separation ring lock lever 51 when the feed unit 21 is closed. good.

  In the above embodiment, the case where the separation ring 14 is urged by the spring in the opening direction has been described as an example. However, after the urging force is eliminated and the feed unit 21 is opened, the operation is performed. If necessary, the separation ring 14 may be swung in the opening direction by manual operation. With this configuration, the number of parts can be reduced.

  The above-described configuration can be applied to either the case where the coin processor 11 is provided on the upper surface side or the case where the coin processor 11 is provided.
