The gear 37a is transported by the transport motor. The gear 37b is attached to the central axis of the transport roller 35 and meshes with each other.

  A coin receiving portion 38 similar to the coin receiving portion 17 of the first transport disk 16 is provided on the outer peripheral portion of the second transport disk 33, and a central shaft 39 is provided on the second transport disk 33. The gear 20d, which is engaged with the gear 20a attached to the rotation shaft of the transport motor 19 via the gear 20c, is fixed to the central shaft 39, whereby the second transport disk 33 rotates the first transport disk 16. Rotated in the direction opposite to the rotation direction (clockwise direction in FIG. 1) (counterclockwise direction in FIG. 1) of the first conveyance disk 16 via the gears 20a, 20c, and 20d by the transfer motor 19 to be received. The coins that have entered the section 38 are conveyed along the outer peripheral wall surface 14.

  That is, the second transport disk 33 shares the first transport disk 16 and the transport motor 19, and rotates intermittently as described later in synchronization with the first transport disk 16 by driving the transport motor 19. The positions of the coin receiving portions 38 and 17 are managed based on whether the position detection sensor 22 is on or off.

The direction in which the coin C is transported by the transport roller 35 is set so as to be shifted with respect to the central axis 39 of the second transport disk 33 and is also set so as to be shifted with respect to the central axis 18 of the first transport disk 16. ing.
The sorting unit 32 is provided with a second coin detection sensor 31 that detects the presence or absence of the coin C in the coin receiving portion 38 facing the coin delivery area 26.

  On the other hand, the bottom surface 15 of the transport unit 13 is provided with sorting holes 34a, 34b, 34c, 34d, 34e, and 34f for sorting and dropping coins C of each denomination. Corresponding to the coins of denominations, it is provided in a size corresponding to the diameter of the coin C of each denomination, but the length in the direction orthogonal to the transport direction is an ellipse slightly longer than the length in the transport direction. These sorting holes 34a, 34b, 34c, 34d, 34e, and 34f are arranged in order from the smaller diameter of the coin C. That is, the sorting hole 34a corresponds to 1 yen coin, the sorting hole 34b corresponds to 50 yen coin, the sorting hole 34c corresponds to 5 yen coin, the sorting hole 34d corresponds to 100 yen coin, the sorting hole 34e corresponds to 10 yen coin, and the sorting hole 34f corresponds to 500 yen coin. It is supposed to be.

The operation of the above configuration will be described.
Note that the operation of each unit described below is controlled by a control unit (not shown) based on a program (software) stored in a storage unit (not shown).

  First, when coins are put together from a coin slot on the upper surface of the hopper 2 of the coin feeding unit 1, the coins 2 are guided and accumulated on the feeding disk 3 by the hopper 2. When the insertion of the coin C is detected by a sensor (not shown), the feeding motor 5 is driven, the feeding disk rotates counterclockwise as indicated by an arrow in FIG. 1, and the coin C is moved outward by the centrifugal force. The coin C is regulated by the feeding port 8 opened in the disc guide member 7 and fed to the coin passage 9 one by one.

  The fed coin C stays as it is when the transport roller 10a is not rotating, and when the transport motor 11 is driven to rotate the transport roller 10a, the coin C is sandwiched between the transport rollers 10a and 10b and the transport unit 13 side. It is conveyed to.

  Further, the first transport disk 16 of the transport unit 13 is rotated by the transport motor 19, but the coin receiving portion 17 faces the coin passage 9 triggered by a change in the position detection sensor 22 from ON to OFF by the shielding member 23. Control is made to stop at the position, stop for a preset time, and then rotate again. In this case, since the slits of the shielding member 23 are arranged at equal intervals, the first transport disk 16 rotates intermittently at regular intervals.

  When the pre-feed sensor 28 detects the coin C sandwiched between the transport rollers 10a and 10b, the position where the coin receiving portion 17 faces the coin passage 9 in synchronization with the position detection sensor 22, that is, the position where the coin C can be received. In such a state, the drive of the transport motor 19 is stopped so that the first transport disk 16 stops, and then the transport motor 11 is driven to rotate the transport rollers 10a and 10b to feed the coin C to the coin receiving portion 17. Include.

Since the bottom surface 15 of the transport unit 13 is set to be slightly lower than the bottom surface of the coin C sandwiched between the transport rollers 10a and 10b, it can be smoothly fed without being caught.
When the coin C is fed into the coin receiving unit 17 and the coin C is detected by the first coin detection sensor 24, the driving of the transport motor 11 is temporarily stopped, and the coin C is delivered to the transport unit 13. Ends. Thereafter, the driving of the transport motor 19 is resumed and the first transport disk 16 rotates.

By continuously performing the above operations, the coins C inserted into the feeding unit 1 are sequentially transported to the transport unit 13, and the coins C are sent one by one to each coin receiving portion 17 of the first transport disk 16. Go.
In addition, when the detection (ON) of the coin C by the pre-feed sensor 28 and the ON condition by the shielding member 23 of the position detection sensor 22 do not match, that is, when there is no coin receiving portion 17 at an acceptable position, the transport motor 11 is Stop until the next coin acceptor is in an acceptable position.

  Further, since the conveyance direction of the coin C by the conveyance rollers 10 a and 10 b is set slightly deviated from the rotation shaft 18 of the first conveyance disk 16, the coin C enters obliquely with respect to the coin receiving portion 17. The first transport disk 16 rotates in a direction to escape from the transport rollers 10a and 10b, so that the coin C is locked between the transport rollers 10a and 10b and the first transport disk 16. Can be prevented.

  The coin C sent to the coin receiving portion 17 of the first transport disk 16 is intermittently transported along the outer peripheral wall 14 by the intermittent rotation of the first transport disk 16, and the coin C is discriminated in the middle of the transport. Passes the position of sensors 25a, 25b, 25c. At this time, the recognition sensors 25a, 25b, and 25c acquire various characteristic values (size, presence / absence of a hole, material, etc.) of the coin C passing over one sensor per intermittent conveyance, and acquire all sensor acquired values. Using the discriminating means (control unit) discriminates the authenticity and denomination of the coin C.

  As a result, if the coin C is a normal coin with a true denomination, the coin C is transported to the coin delivery area 26, and then the transport motor 35 is driven to rotate the transport roller 35, thereby transporting the transport roller 35. Then, the coin C is sandwiched between the bottom surfaces 15 and 30 and conveyed to the sorting unit 32, and the coin C is fed into the coin receiving portion 38 of the second conveying disk 33.

  Also in this case, the conveyance direction of the coin C by the conveyance roller 35 is set slightly deviated with respect to the rotation shaft 39 of the second conveyance disk 33, so that the coin C enters the coin receiving portion 38 obliquely. Then, since the second transport disk 33 rotates in the direction of escaping from the transport roller 35, the coin C can be prevented from being locked between the transport roller 35 and the second transport disk 33. . The coin C sent to the coin receiving unit 38 is detected by the second coin detection sensor 31.

  Although not shown in the present embodiment, a similar conveyance roller may be provided under the conveyance roller 35, and the coins C may be sandwiched and conveyed between the rollers like the conveyance rollers 10a and 10b.

  The second transport disk 33 of the sorting unit 32 shares the first transport disk 16 and the transport motor 19, so the second transport disk 33 is driven together with the first transport disk 16 by driving the transport motor 19. The coin C is intermittently rotated, and the coin C is sent to each coin receiving portion 38 along with the rotation, and the coin C sent to the coin receiving portion 38 is transported by the rotation of the second transport disk 33 to be denominated. When it is transported to any of the corresponding sorting holes 34a, 34b, 34c, 34d, 34e, 34f, it falls into the corresponding sorting hole. The success or failure of the dropped coins falling into the target sorting holes is confirmed by a drop detection sensor (not shown) provided in each hole.

In addition, the dropped coins are accumulated in the temporary accumulation unit according to the type of money, and after all the coins C that have been inserted are discriminated and counted, the counting result is displayed on a display unit (not shown), and the coin inserter instructs the deposit The coin C accumulated in the temporary accumulation unit is stored in the storage unit according to denomination.
The above is the operation in the case of a normal coin. However, when it is determined as a reject coin having an abnormality such as false or denomination by the above determination, the coin C is transferred to the coin delivery area by the rotation of the first transport disk 16. When transported to 26, the transport roller 35 is kept from rotating.

  Since the direction of the transport roller 35 is set so as to be shifted with respect to the central axis 18 of the first transport disk 16, it is positioned obliquely with respect to the coin receiving portion 17, and the first transport Since the disk 16 rotates in the direction of escaping from the transport roller 35, it is possible to prevent the coin C, which is a reject coin, from being pinched between the first transport disk 16 and the transport roller 35 and locked. Thereafter, the reject coin is conveyed to the reject coin discharge port 27, led from the reject coin discharge port 27 to a return unit (not shown), and returned to the coin thrower.

  As described above, in the first embodiment, the transport unit 13 having the rotatable first transport disk 16 provided with a plurality of coin receiving portions 17 cut out in a U shape on the outer peripheral portion, and the outer peripheral portion. Similar to the coin receiving portion 17, a sorting unit 32 having a rotatable second transfer disk 33 provided with a coin receiving portion 38 is provided adjacent to the first transfer disk 16 by the rotation of the first transfer disk 16 of the transfer unit 13. When the coin C stored in the coin receiving portion 17 of one transport disk 16 is transported, the authenticity and denomination of the coin are discriminated, and the coin C provided on the second transport disk 33 of the sorting unit 32 is received. Then, the coin C is transferred to one of the sorting holes 34a, 34b, 34c, 34d, 34e, and 34f corresponding to the denomination by the rotation of the second transfer disk 33 and dropped. Because, the conveyance path length of the coin can be shorter than the structure linearly arranged coins chute of the coin discriminating means and denomination, there is an advantage that it is possible to reduce the size of the apparatus.

FIG. 3 is a plan view of a sorting unit showing a second embodiment of the present invention.
In the second embodiment, guides 40a, 40b, 40c, 40d, 40e, 40f that open and close are arranged in the sorting holes 34a, 34b, 34c, 34d, 34e, 34f of the transport denomination sorting disk unit 32. Thus, each guide is individually operated by a driving mechanism such as a motor and gear (not shown) or a solenoid.

  Here, for example, the guide 40a is opened when the guide 40a horizontally moves to a position outside the outer peripheral wall surface 29 as shown by a broken line, that is, not completely hooked on the sorting hole 34a, and the outer peripheral wall surface 29 is shown as a solid line. When the coin C other than the denomination to be dropped has been transported, the closed state is defined as the time when the coin C moves to a position covering the sorting hole 34a on the inside, and the closed state is maintained so that the coin C does not fall into the sorting hole 34a. In this way, the opening and closing is controlled according to the discrimination denomination.

The guides 40b, 40c, 40d, 40e, and 40f are the same, and by doing so, the sizes (diameters) of the sorting holes 34a, 34b, 34c, 34d, 34e, and 34f can be made the same. Arbitrary denominations are assigned to the sorting holes 34a, 34b, 34c, 34d, 34e, 34f.
Although not shown in FIG. 3, the coin feeding unit 1 and the transport unit 13 and the like are the same as those in the first embodiment, and therefore the coin feeding unit 1 and the transport unit 13 and the like are as shown in FIGS. Reference 2

The operation of the above configuration will be described.
The operations of the coin feeding unit 1 and the transport unit 13 are the same as those in the first embodiment. After the authenticity and denomination of the coin C are determined, the coin C is delivered from the coin delivery area 26 to the sorting unit 32. The coin C is fed into the coin receiving portion 38 of the second transport disk 33. The coin C sent to the coin receiving unit 38 is detected by the second coin detection sensor 31.

  The coin C sent to the coin receiving unit 38 is transported to any of the sorting holes 34a, 34b, 34c, 34d, 34e, 34f based on the denomination result of the transport unit 13. For example, when the coin C sent to the coin receiving unit 38 is a 100 yen coin and the sorting hole 34e is assigned to the denomination, the coin C is selected as a target by the rotation of the second transport disk 33. It is conveyed to the hole 34e.

  Thus, when the coin C is conveyed to the sorting hole 34e, the guide 40e is horizontally moved to an open state by a drive mechanism (not shown), whereby the coin C falls into the sorting hole 34e, and the coin C is dropped at this time. After being detected by a sensor (not shown) and confirmed to drop, the guide 40e is closed by the drive mechanism. The dropped coins are accumulated in the temporary accumulation unit by denomination.

  The same processing is performed for coins of other denominations. After all the coins C that have been inserted are discriminated and counted, the counting result is displayed on a display unit (not shown), and the coin thrower inputs an instruction for depositing. When done, the coins C accumulated in the temporary accumulation unit are stored in the storage unit in denomination.

  In the second embodiment described above, guides 40a, 40b, 40c, 40d, 40e, and 40f are provided in the sorting holes 34a, 34b, 34c, 34d, 34e, and 34f of the sorting unit 32, and the guides 40a, 40b, and 40c are provided. , 40d, 40e, and 40f are controlled so as to drop the coin C of the corresponding denomination from the sorting holes 34a, 34b, 34c, 34d, 34e, and 34f. In addition, the diameters of the sorting holes 34a, 34b, 34c, 34d, 34e, and 34f are made the same, thereby assigning an arbitrary denomination to the sorting holes 34a, 34b, 34c, 34d, 34e, and 34f. Can be obtained, and the effect of improving convenience is obtained, and the opening and closing operation of the guides 40a, 40b, 40c, 40d, 40e, 40f is achieved. Since the coin C can be reliably dropped into the relevant sorting hole, there is an advantage that it is possible to prevent erroneous dropping of the coin C.

  In each of the embodiments described above, regarding the coin delivery area 26 and the reject coin discharge port 27 of the transport unit 13, the reject coin discharge port 27 is provided downstream of the coin delivery area 26 in the coin transport direction. It is also possible to arrange in this way.
