Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coin sorting device for sorting by type so-called mixed coins in which a large amount of coins of different denominations are mixed together.

Conventional devices of this type include a rotating disk unit that aligns mixed coins in a single column and continuously discharges them, and a sorting track provided at the discharge port of the rotating disk unit and having various sorting holes with different widths formed in the bottom surface. and a sorting belt mechanism that transports the mixed coins on the sorting track in one direction, and the coins aligned by the sorting belt mechanism are drawn into the sorting track, transferred, and mixed into the various sorting holes mentioned above. Coins were dropped by type. Such conventional devices (for example, Japanese Patent Publication No. 45-340
No. 84, Japanese Patent Publication No. 39-13111), a sorting belt mechanism was provided such that only one belt was provided over the entire length of the sorting track, and was inclined with respect to the direction of the track.

The above inclination is to send the coins closer to the reference wall of the track, but since it is a single belt, the inclination is gentle, so the above contact action is insufficient, and it is difficult to send the coins to the sorting hole reliably. There was a risk that it would not be possible to drop it. Furthermore, since the transfer is carried out using a single belt, if a small-diameter coin is transferred while being sandwiched between the front and back by a large-diameter coin, there is a risk that the coin may not fall reliably into a predetermined sorting hole. The present invention has been made in view of the above circumstances,
By providing one belt for each sorting hole to make the belt slope steeper, by partially overlapping each belt on the sorting bottom plate, and by gradually accelerating the transfer speed of each belt, it is possible to ensure reliable and quick transfer. It is an object of the present invention to provide a coin sorting device capable of sorting coins.

An embodiment of the present invention will be described in detail below with reference to the drawings.

The present invention can be roughly divided into mixed coins Cl, C2...
A rotating disk section 1 for discharging Cn in a continuous line in a column by its rotational centrifugal force; various sorting holes 3a connected to the discharge port 2 of the rotating disk section 1 and having different slots on the bottom;
3b...3n, and a sorting belt mechanism 5 that transports the mixed coins Cl, C2...Cn on the sorting track 4 in one direction. .

The rotary disk portion 1 has a sorting ring 7 provided on the circumferential surface of the disk 6, and a coin alignment course 8 formed near the discharge port 2.

The disk 6 has a large gear 1 fixed to a rotating shaft 9 of the disk 6.
A small gear 11 is meshed with the small gear 11, a drive pulley 13 is fixed to one end of a shaft 12 of the small gear 11, and the drive pulley 13 is rotated by a motor 14. When the motor 14 is operated, the drive pulley 13
rotates, and when the small gear 11 rotates due to the rotation of the shaft 12, the large gear 10 rotates, and the rotation of the large gear 10 causes the rotating shaft 9 to rotate.
The disk 6 rotates through the rotation of the disk 6, and the mixed coins Cl, C2...Cn on the disk 6 are sent along the sorting ring 7 to the coin alignment course 8. The mixed coins Cl, C2, . . ., Cn are arranged in a single column and sent out continuously. The sorting track 4 has a reference rail 15 and a sorting rail 16 arranged in parallel at a predetermined interval.

Furthermore, the sorting edge 16a of the sorting rail 16 where the sorting hole 3a is formed has the largest protrusion length, and the protrusion length is gradually made smaller.

b-...3n, and the distance between each coin transfer belt 20a, 20b...20n and the reference rail 15 gradually decreases as the belt runs. The frame is stretched so as to be inclined with respect to the reference rail 15.

The belt transfer mechanism 19a, 19b...19n
Among them, the belt transfer mechanism 19a, in which the coin transfer belt 20a is stretched over the passage bottom plate 18, is driven by one drive pulley 22 of pulleys 22a and 23a provided at both ends of the rotating shaft 21a.
The rotation of the drive pulley 13 is transmitted to the drive belt 27a to the other pulley 23a.
A coin transfer belt 20a is stretched between the pulley 24a and the subordinate pulley 24a provided on the arm 25a. The arm 25a is configured to be pivotable about the pivot portion 26 as a fulcrum. The subordinate pulley 24b of the next belt transfer mechanism 19b is arranged to overlap the pulley 23a on the sorting bottom plate 17, and the rotation of the drive pulley 22a is transmitted to the drive pulley 22b by the drive belt 27b. ing.
A subordinate pulley 24c of the belt transfer mechanism 19c is also arranged so as to overlap the pulley 23b on the sorting bottom plate 17,
The rotation of the drive pulley 22b is transmitted to the drive pulley 22c by a drive belt 27c. The belt transfer mechanism 19d and the following are similarly configured. A coin guide tube (not shown) is connected to each of the sorting holes 3a, 3b, . . . 3n, and the coins are counted after passing through these guide tubes.

is discharged to. Mixed coins Cl sent to outlet 2,
c2...Cn are transferred in one direction on the passage bottom plate 18 of the sorting track 4 by the coin transfer belt 20a of the belt transfer mechanism 19a. The mixed coins Cl, c2, . . . , Cn transferred by the coin transfer belt 20a are delivered to the coin transfer belt 20b of the belt transfer mechanism 19b. While being transported by the belt 20b, the coin C1 with the smallest diameter is dropped into the sorting hole 3a. That is, mixed coin Cl
, c2, . The coin C1 with the smallest diameter is transferred while being placed on the side surface of the reference rail 15 while pressing against the side surface of the reference rail 15, but the portion opposite to the portion of the smallest diameter coin C1 that is pressed against the side surface of the reference rail 15 is the sorting edge 16a of the sorting rail 16. The coin C1 separates from the screen and falls into the sorting hole 3a. A coin C2...Cn having a larger diameter than the coin C1 has a guide edge 15.
a and the sorting edge 16a, the coin passes through the sorting hole 3a without falling, and is delivered to the coin transfer belt 20c of the next belt transfer mechanism 19c. This delivery is done on the sorting bottom plate 17.
Since this is done at the top, troubles due to delivery are prevented. During the transfer by the coin transfer belt 20c, a coin C2 having the next smallest diameter after the coin C1 is dropped into the sorting hole 3b. Similarly, coins C3, c4...-Cn are sequentially sorted through the sorting hole 3.

You can easily remove the deformed coin by lifting it upward from 6n. Note that the sorting hole 3 formed in the sorting track 4
The numbers a, 3b...3n are set according to the number of types of coins to be sorted (six types of domestic coins, including the old 50 yen), and are each formed to have a width slightly wider than the coin diameter. Of course. Furthermore, each belt transfer mechanism 19

, 20b, . . . , 20n are set to increase sequentially by means such as making the diameters of the drive pulleys 22a, 22b, . . . , 22n different. The gap between each coin on the sorting track 4 increases as the coins are transported, so that the small diameter coin C1 passes through the sorting hole 3a without falling while being sandwiched between the large diameter coins, such as C3. Make sure to prevent such situations. As described in detail above, according to the present invention, the sorting belt mechanism for transferring mixed coins on the sorting track in one direction is composed of a plurality of belt transfer mechanisms, so that one belt can cover the entire length of the sorting track. The angle of inclination can be adjusted to a sufficient degree compared to the conventional structure which is stretched across ρ.

Therefore, the transferred mixed coins reliably contact the side surface of the reference rail, and the portion opposite to the contact portion reliably separates from the sorting rail, thereby ensuring that the mixed coins fall into the sorting hole where they should fall and are sorted. Ru. In addition, each belt of the sorting belt mechanism is provided corresponding to each sorting hole, and the preceding belt and the next belt partially overlap on the sorting bottom plate, so that coins are always kept on the belt. In addition to being able to keep the coins in contact and being transported parallel to the sorting track at all times, the sorting bottom plate supports the bottom surface of the coins even when the coins are transferred to overlapping (adjacent) belts where the parallel state of the coins is likely to be disrupted. This allows the parallel state to be maintained, and the occurrence of jams can be suppressed as much as possible. Furthermore, since the moving speed of each belt in the sorting belt mechanism is configured to gradually increase, even if the coins are fed into the sorting track in a state where they are in contact with each other, the intervals between each coin will gradually increase. A reliable selection is carried out. Therefore, there are effects such as preventing jams, achieving high-speed transfer, and increasing sorting efficiency.
