Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic washing device for coins and the like.

(Prior Art) Coins and the like dedicated to game machines such as throttle machines become quite dirty with dirt and dust that accumulate during use, and therefore require periodic cleaning.

Therefore, it is conceivable to put a coin or the like into a drum such as a mixer and to mix and wash the coin and the like together with the cleaning liquid.

(Problem to be solved by the invention) However, in this case, a large amount of coins, etc. must be washed several times due to the volume inside the drum, and it takes a lot of effort to put in and take out coins, etc. There was a problem that it required .

Therefore, an object of the present invention is to provide an automatic washing device that can continuously stir and wash a large amount of coins and the like.

(Means for Solving the Problems) Therefore, the present invention has a plurality of box-shaped trap portions arranged in the feeding direction so that each trap portion is located between adjacent trap portions on the opposite side with a communicating passage portion extending straight between the trap portions. This casing is connected to a carrier casing ring which is arranged continuously along the trap and has an inclined guide formed on the rear end face of each trap part in the feeding direction to collect objects to be cleaned falling from the opposite trap part towards the front end side. Equipped with a drive means that rotates the passage around its axis, one end of the carrier casing ring is provided with an inlet for the object to be cleaned, and the other end is provided with an outlet, while each trap part is formed with a large number of small holes. At the same time, a cleaning tank is provided for immersing at least a plurality of trap portions located in the intermediate portion of the carrier casing in cleaning water.

(Function) The carrier casing ring is rotationally driven by the driving means, and as a result, the vertical position of each trap portion is reversed every 1/2 rotation. Therefore, the objects to be cleaned (such as coins) that are fed into the carrier casing in appropriate amounts fall from the inlet into the first trap section and are collected toward the front end by the inclined guide, and when this trap section comes upward, It falls into the next trap section on the opposite side and is also collected on the front end side by the inclined guide.

In this way, the object to be cleaned inside the carrier casing is repeatedly dropped every 1/2 rotation as it passes through the cleaning tank and is transported to the outlet.
Even in the cleaning liquid, the objects to be cleaned collide with each other or rub against each other due to the stirring action when they fall, so that dirt attached to the objects to be cleaned can be cleaned and removed.

(Example) In Figs. 1 and 2, numeral 1 denotes a carrier casing ring which is rotatably supported at both ends of a housing 2, and inside the housing 2, there is a garbage dropping tank below the carrier casing ring 1 and along it. 3. The cleaning tank 4, the rinsing tank 5, and the drying tank 6 are arranged adjacent to each other. Note that the cleaning liquid is in the cleaning tank 4, and the cleaning liquid is in the cleaning tank 5.
The inside is filled with water, and the drying tank 6 is provided with a blower for blowing warm air toward the carrier casing ring 1.

The carrier casing ring 1 has a plurality of box-shaped trap portions 7 arranged on one side of a communicating passage portion 8 having a rectangular cross section extending straight, and on the opposite side thereof, each trap portion 7 is arranged between adjacent trap portions 7 on the opposite side. The traps are arranged continuously along the passage section 8 so that the objects to be cleaned, such as coins, which fall from the trap section 7 on the opposite side are placed on the rear end surface of each trap section 7 in the feeding direction. A tilted guide 9 is formed which gathers to the side.

In this case, each trap section 7 is made by stretching a wire mesh over the entire surface of the frame, and is attached to the frame of the communicating passage section 8 by bolting. Further, the communication passage section 8 is made by pasting a plate material to the entire surface of the frame except for the trap mounting surface. In addition, each tank 3
The trap portion 7 located between the trap portions 3 to 6 is reduced to a size that does not interfere with the partition walls of the tanks 3 to 6 when the carrier casing ring 1 rotates.

A cylindrical inlet 10 that opens into the first trap section 7 is integrally formed at one end of the carrier casing ring 1, and an outlet opening facing the front end in the last trap section 7 is formed at the other end. 11 is the passage section 8
It is opened in the side wall.

Pulleys 12 and 13 are rotatably supported via rollers 15 on stays 14 on both sides of the housing 2, and the pulley 12 has the inlet 10 of the carrier casing ring 1, and the pulley 13 has the communication passage 8. are fitted together so that they can rotate together. Here, the pulley 12 is connected via a belt 18 to a pulley 17 attached to the rotating shaft of an electric motor 16, and transmits the driving force from the motor 16 to the carrier casing ring 1 to center it around the axis of the connecting passage section 8. It is designed to rotate.

In addition, 19 is a dropper for dropping and feeding coins or the like in appropriate amounts through a duct (not shown) inserted into the introduction port 10 of the carrier casing ring 1;
0 indicates a chute that receives coins and the like falling from the outlet 11 and guides them into a storage box (not shown) outside the housing 2.

With such a configuration, the carrier casing ring 1 is rotationally driven in a predetermined direction by the electric motor 16, and as a result, the vertical position of each trap portion 7 is changed by 1/2.
It flips every two revolutions. For this reason, for example, dirty coins are fed into the carrier casing ring 1 in appropriate amounts from the potper 19, fall from the inlet part 10 into the first trap part 7 located on the lower side, and are collected on the front end side by the inclined guide 9. This trap part 7
When it reaches the upper side, it falls into the trap section 7 on the opposite side and is also collected at the front end side by the inclined guide 9.
Furthermore, when this trap part 7 comes to the upper side, it falls into the next trap part 7 on the opposite side and again the inclined guide 9
are gathered toward the front end.

In this way, the dirty coins repeatedly fall within the carrier casing ring 1 every 1/2 rotation, pass through each tank 3 to 6 in turn, and are conveyed to the outlet 11. Due to the stirring action, for example, coins collide or rub against each other, which improves the removal of dirt. in this case,
First, the dirt and dust on the coins are sieved off in the dust removal tank 3, then the decomposition of oil stains is promoted in the cleaning tank 4, and the floating oil stains are washed clean with water in the washing tank 5, and finally, Water attached to the coins is removed in a drying tank 6.

Therefore, according to this embodiment, coins and the like can be continuously conveyed and washed while being stirred in the carrier casing ring 1, and when the carrier casing ring 1 is replaced with a screw conveyor. In comparison, it has excellent stirring action and good cleaning effects. Also, it puts strain on the drive system to agitate and convey coins, etc. (coins and the like can get caught in the screws on a screw conveyor).
Not at all.

(Effects of the Invention) In summary, according to the present invention, the carrier casing ring loses 1/2 of the coin, etc. inside as it rotates.
Since the stirring action and the conveying action are performed jointly while dropping each rotation, it is possible to continuously and effectively wash dirty coins and the like.
