[Problems that the invention will solve]

In the above-mentioned conventional tilted disk type coin sending device, large and small diameter coins are received and lifted in the scraping portion for lifting the coin L1, so relatively small coins are picked up by scraping. Because of the movement within the raking unit, the raking unit may fall out of the raking unit before reaching a predetermined delivery position, which poses a problem in that reliable lifting and delivery cannot be performed.

In addition, in the conventional device, the raking portion of the depression Iυ (in FIG.
Since the coins were accepted into the slot (consisting of the recessed part 6 and the guide 7 in Figure 1) and the vA was carried out one by one, the only coins that could be used were those with a diameter difference of twice or less. I couldn't do that. In other words, if a conventional device were to simultaneously throw in coins whose diameters are more than twice as large and send them out for scraping, the size of the single recessed scraping portion would be slightly larger than the largest diameter coin. Because it is formed large, there are two coins with the smallest diameter in the recessed part.
If more than one coin is inserted into the machine, two coins are sent out at the same time, causing problems such as coin jams, erroneous sorting, and erroneous identification in subsequent steps.

Therefore, with conventional devices, there is a problem that it is not possible to reliably feed out coins one by one, and in particular, it is impossible to process coins whose diameters differ by more than twice, which is a fatal drawback. was there.

The present invention has been developed in view of the above-mentioned points, and it is possible to reliably rake and send out coins one by one, and also to reliably rake only one coin when the diameter difference is twice or more. It is an object of the present invention to provide an inclined disk-shaped coin dispensing device that is capable of lifting and discharging coins one by one.

[Failure to solve the problem]

The present invention provides an inclined disk 1 rotatably supported in an inclined state.
10 A scooping part 17 for scooping out the coin C on the outer peripheral edge of the surface 1
A plurality of coin lifting claws 15 formed almost perpendicularly to a holding portion 16 that holds only one coin C are each rotatably provided. In the inclined disk type coin sending device provided with a control mechanism 23 for changing and controlling the angle, as the inclined disk 11 rotates, the coin lifting pawl 15 moves the inclined disk 1 in the scooping section 17.
The coins C stored in the lower surface area of 1 are lifted up to create an inclined circle a.
811, the above-mentioned control mechanism 23 changes and controls the rotation angle of the coin scraping claw 15 during the movement toward the upper region, whereby the scooping part 17 and the holding part 16 holds only one coin C and moves to the coin sending position in the upper area of the inclined disk 11 while maintaining the holding posture.

[Effect]

In the present invention, the scooping portion of the coin lifting claw scoops up the coins stored in the lower surface area of the inclined disk to the holding portion as the inclined disk rotates, and the scooping portion scoops up the coins together with the holding portion. Then, while holding the coin, the coin lifting claw moves to the upper area as the inclined disk rotates, and during the movement, the control mechanism controls the coin to maintain a constant holding posture. Then, the remaining coins are dropped leaving only one coin on the coin i lift, and only the remaining coins are scraped and lifted to the sending position.

2 are generally divided into 12 series corresponding to each denomination.

Next, the operation of this embodiment will be explained.

First, the operation of transporting the coins C input and stored in the lower region' of the inclined disk 11 to the upper region by the lifting die 15 is carried out in the sixth step.
This will be explained with reference to the figures.

When coins C of different denominations are mixed in the hopper 28, the inclined portion 1lA11 is rotationally driven to collect the coins C,
Position of point a, which is the lowest point of the inclined disk 11 (it can also be seen from the upstream side of point A) J: The scooping part 17 of the scooping mold 15 scoops up the coin C along with the same level of the inclined disk 11. Raise the coin C onto the scooping part 17 and the holding part 16 and move it to the inclined disk 11.
WIwJ moves towards point b.

When the raking mold 15 reaches point b, the holding part 16 of this raking mold 15 assumes a horizontal position, and at the time it reaches point b), the 1-ra 20 of the cam driven member 19 is moved to the position of the cam member 23. The gate from point b to point 0 contacts the cam surface 24, and the D-520 slides along the cam surface 24, and the holding part 16 of the scraping die 15 moves while remaining in a horizontal position. Transport one fried coin C to point 0.

Furthermore, while the coins C having a relatively small diameter are transported from point a to point b, a plurality of coins C such as two or three coins C may be simultaneously lifted by one lifting die 15. However, from the position of point b where the holding part 16 is horizontal,
Since the lifting die 15 moves while the holding part 16 is kept horizontal, only one of the coins C lifted at the same time remains, and the other coins C fall.

When the 1!1 lifting claw 15 reaches the 0 point while holding only one coin C, that coin C is completely removed from the inclined disk 11.
The sensor 31 disposed on the coin guide 29 is delivered onto the surface of the coin guide 29 which is outside the rotation range of the coin guide 29.
The denomination, etc. of the coin C is identified.

Further, when the coin C passes through the zero point, the coin C is dropped onto the conveyance path 35 between the conveyance fins 25 and 25 via the inclined portion 30 of the coin guide 29, and the coin C is dropped onto the conveyance path 35 between the conveyance fins 25 and 25.
25 on the conveyance path 35, and the scraping mold 1
5, the cam driven member 190 roller 20 is moved from the cam surface 24 of the cam member 23 after the coin C is dropped onto the conveyance path 35.
leaves and returns to the same initial position as point a, preparing for the next raking.

As described above, the raking type 15 rakes up the coin C between points a and b, and maintains the posture of the holder 16 horizontally between point a and point 0. Scratch 15) Lost coin C
The coin C held at point A is conveyed while holding it as one (), and at point 0, the coin C held in A is sent out to the conveyance path 35 to return to the initial position.

Next, an explanation will be given of the operation of storing the coins C, which have been lifted by the lifting die 15 and whose denominations have been identified by the sen 1 no. 31, into the coins 51 for each denomination.

The coin C dropped onto the conveyance path 35 between the conveyance fins 25 and 25 moves along the conveyance surface 36 of the M conveyance path 35 as the inclined disk 11 rotates, and reaches the rear end of the forward conveyance fin 25 covering the conveyance surface 36 of the conveyance path 35. The paper is transported IIQ while sliding on the transport surface 36 by being attached to the transport surface 36 or being pushed by the rear transport fins 25 .

Coins C are transported by the transport fins 25.
When reaches the branching position of each denomination angle (the placement of the slot 36a), if the coin IJ is not the coin C that should be branched at that branching position, then
The coin C and the conveyance fin 25 are placed above the slot 36a J5.
, and passes under the receiving member 46 (see FIG. 3).
. If the coin C is to be branched at that branching position, the rotary solenoid 45 is turned on and each branch is turned on when the conveyance fin 25 located in front of the coin C reaches the corresponding slot 36a-L. A protrusion 42 projects from each slot 36a onto the conveying surface 36, and a conveying fin 25.
25, the coin C is turned N1 from the conveying surface 36 according to the branching surface 43 of the branching protrusion 42 and is pushed upward by 1
- is kicked off and rests on the receiving member 46 (see FIG. 4);

Then, the coins C placed on the receiving member 46 are
52, the coins are led out and stored in the coins 51 for each denomination.

Next, the principle of holding and conveying large-diameter coins and small-diameter coins C one by one by the lifting die 15 will be explained.

Since the raking die 15 is formed to be somewhat thinner than the thickness of the thinnest coin C to be processed, the coins C are not raked in an overlapping state.

Further, the length dimension of the holding portion 16 of the raking mold 15 is determined as follows. As shown in FIG. 7, since the holding portion 16 of this scraping die 15 holds the coin C in a placed state, the centrifugal force F1 of the hard 92C due to the rotation of the inclined disk 11
and gravity G [If the mouth is within the range above the holding portion 16, the coin C can be held. In other words, gravity G
is always downward, so at the position of point b (see Figure 6) where the horizontal component of centrifugal force F1 is largest,
Coin C can be held if the resultant force F o+ with 11 and the centrifugal force F12 which is d3 at the position of the 0 point where the horizontal component is the smallest 1 mouth 2 is within the range above the holding part 16. Therefore, the length of the holding part 16 is the resultant force Fo+, F
The length is determined within the range of oz. Also, at this time, the scooping part 17 of the scooping die 15 acts to catch the horizontal component of the centrifugal force of the coin C, so the coin C does not fly outward, and the length of the scooping part 17 Well, coin C
By shortening the coin C within a range that does not protrude outward of the inclined disk 11, the outer periphery of the coin C in the outward direction is removed from the scooping part 17.
The holding portion 16 can be extended further outward, and therefore, even if the holding portion 16 has a length less than half the coin diameter, it is possible to raise a large-diameter coin C without dropping it.

In addition, when two or more small-diameter coins C are lifted up on the holding part 16 of the Wl lifting claw 15 in a parallel state, as shown in FIG. 8, the holding part 16 becomes horizontal at point b. At the position, the coin C located on the outer circumference side of the inclined disk 11 is completely on the holding part 16 and will not fall, but the coin C located on the center side is affected by centrifugal force F11, gravity G and 6 Resultant force F
At comes off from the tip of the holding part 16 and falls off from the holding part 16. As the point moves from point b to point 0, the direction of the resultant force F o+ approaches the same direction as the vertically downward gravity G, making it easier for the coin C on the center side to fall, and Even if the coin C is small in diameter, it falls down to the position and is held on the holding portion 16 even if it is a single coin C ( ).

〔Effect of the invention〕

According to the present invention, the coins stored in the lower area of the inclined disk are reliably scooped up by the holding part and the scooping part of the coin scraping claw, and the rotation and angle of the coin scraping claw are changed during the scooping. By controlling the coins, it is possible to always hold at least one coin on the coin lifting claw and send it out. Moreover, by setting the dimensions of the holding part and the adding part of the coin lifting claw, the diameter difference can be reduced to 2. More than double
- Even when processing different coins, it is possible to input them at the same time and send them out one by one.
