At that time, the flow rate of the liquid F flowing to the main plate 3 and gate plate 4 is controlled in the deceleration direction by the guide bases 3b and 4b formed on the main plate 3 and gate plate 4, and is blocked and downward. It does not fall downward suddenly.

As shown in FIG. 5, the liquid F that travels between the fins 3a of the main plate 3 and falls is blocked by the guide base 3b (FIG. 3), and falls over the fins 3d and the inclined surface 3e. passing through and being guided below, and collecting part 1
It falls into the box 13 that constitutes 2.

On the other hand, the liquid F guided between the fins 48 of the gate plate 4 is blocked by the weir 4b (Fig. 4) and flows through the 88 holes formed in the gate rail 8 and the length of the chute 20 shown in Fig. 5. It is guided into the hole 2Oa, passes between the fins 2Ob formed in the elongated hole 20a, and falls into the box 13 constituting the collection section 12. A portion of the liquid F passing between the fins 2Ob formed in the elongated hole 20a becomes raindrop-like due to the triangular protrusion 20C formed at the lower end of the fin 20b, and the collection portion 12 is formed from this protrusion 20C. It falls into the box 13 and is collected.

In addition, as shown in FIG. 5, the liquid F that comes off the coin slot and falls is formed on the front of the gate plate 4 by a guide plate 30 arranged on the front of the main plate 3 that constitutes the coin slot. The liquid is guided to the chute 4f, and then guided into the coin passage 6 through the hole 41 communicating with the chute 4f.Then, the liquid follows the same process as the liquid guided to the gate plate 4 and collects in the collecting section 12. It falls into the box 13 that makes up the box and is collected. Note that the box 13 constituting the collecting section 12 mainly collects the liquid that falls along the guide grooves 10.10- formed in the main plate 3 and the gate plate 4. As described above, the liquid guided through the guide grooves 10 and 10'' formed in the box 13 falls downward while being blocked by the guide bases 3b and 4b. The collected liquid will therefore overflow from the box 13,
It will not stick to its surroundings. Note that the liquid F that has fallen into the box 13 constituting the collection section 12 is discharged through the discharge passage 14.
The coins are quickly discharged from the left side of the device body 2 to the outside of the coin sorting device 1 through the tube 15 constituting the coin sorting device 1, as shown by the arrow F in FIG.

The coin sorting device 1 is normally arranged above a coin dispensing device (so-called coin changer) that stores and dispenses change, but the liquid F discharged from the coin sorting bag W1 mentioned above is transferred to the coin changer described later. It is discharged through the discharge passage arranged on the left side.

FIG. 7 is a front view showing the above-described coin sorting device 1 attached to a coin changer 40 for storing and dispensing change.

On the left side of this coin changer 40, a tube 41 made of synthetic resin and forming the other side of the above-mentioned discharge passage 14 is disposed, and its upper end 41a connects to the discharge passage 14 disposed in the coin sorting device 1. The tip 15a of the tube 15 constituting one side of the tube 15 is in communication with the other end 15a. In FIG. 7, reference numeral 42 is a cassette-type coin tube that is placed at the lower front of the coin changer 40 and stores change for each denomination, and 43 is a cassette-type coin tube that is placed on the right side of the front of the coin changer 40 and is particularly frequently used. Auxiliary tube for storing change coins, 44.
45 is a change dispensing device that dispenses specific change from each of the above-mentioned coin tubes 42 and 43.

According to the configuration of the discharge passage 14 described above, the liquid F discharged from the left side of the coin sorting bag [1 through the tube 15 is transferred to the tube constituting the other side of the discharge passage 14 disposed on the left side of the coin changer 40. 41 to the outside of the vending machine or the like.

As mentioned above, since the discharge passage 14 is arranged on the left side of the coin changer 40, coins can be removed when replenishing change or performing maintenance and inspection, as shown in FIG. 8, which is a left side view of the coin changer 40. The discharge passage 14 does not interfere with the operation of attaching and detaching the tubes 42 and 43 from the front of the coin changer 40.

In FIG. 8, reference numeral 50 indicates a metal fitting for mounting the tube 41.

〔Effect of the invention〕

As explained above, in the coin sorting device of the present invention, there is a collecting section for collecting liquid falling along the coin passage below the coin passage that directly communicates with the coin input port, and a collecting section for collecting the liquid that is in communication with the collecting section. A discharge passage for discharging the liquid collected in the collecting part to the outside of the coin sorting device is provided, and the liquid falling through the coin passage is disposed on the wall surface of the coin passage that directly communicates with the coin input port. Since the sloped liquid guide groove is formed to guide the liquid toward the discharge path, even if a sticky liquid such as detergent is poured from the coin slot, the liquid will flow through the sloped liquid guided toward the discharge path. To provide a coin sorting device that does not flow into the passage inside the device main body due to the guide groove, and therefore does not adhere to various sorting devices arranged in the coin sorting device, and thus always has a stable sorting function. I can do it. Furthermore, the coin sorting device can be effectively protected against malicious mischief by pouring liquid such as detergent into the coin sorting device, preventing its functionality from deteriorating and preventing damage caused by mischief.

Furthermore, since the guide grooves for guiding the liquid are formed at an angle for vertically falling coins, there is no possibility that vertically falling coins will be caught between the grooves and become jammed.
