Abstract

PURPOSE:To improve the processing capacity by moving substitute coins in great quantities by a wide belt conveyor, and executing washing and drying of both the reverse side and the surface of the coins in the course of its movement. CONSTITUTION:Substitute coins 6 thrown in from a throw-in port 3 are allowed to form a line on a conveyor 7 so as not to be superposed to each other by a wide belt conveyor 7 and a roller brush 8, and thereafter, mounted on a conveyor 9 through a guide plate 10. Subsequently, to the coins 6 on the conveyor 9, a washing liquid is ejected by a washing nozzle 11, the surface which becomes the upper side on the conveyor 9 is washed by a washing brush 12, and thereafter, the reverse side and the surface are inverted and mounted on a conveyor 13. Next, when the coins 6 are being moved by the conveyor 13, the other face is washed by a washing brush 14, they pass through between a pair of upper and lower wiping-off rollers 15 and are wiped off as to its moisture, and thereafter, dropped down into a swing chuter 16. Also, the coins 6 are dried by heat of a high heat lamp heater 17, while being moved along the swing chuter 16, and thereafter, discharged from a discharge port 4 by a conveyor 18.

SUMMARY OF THE INVENTION The present invention is to provide a cleaning method and apparatus which dramatically improves the cleaning ability of a substitute coin and has a high cleaning and drying effect.

[0004]

Means for Solving the Problems In order to solve the above-mentioned problems, the means adopted by the first invention is a step of inserting a substitute coin, and aligning the inserted substitute coins so as not to overlap each other. A step, a step of washing one side of the aligned substitute coins, a step of inverting the one side washed substitute coin, a step of washing the other side of the inverted substitute coin,
The cleaning liquid is removed from the washed substitute coin, the cleaning liquid is removed from the substitute coin, and the dried substitute coin is discharged. It is characterized by being held while holding coins.

Further, the means adopted by the second invention comprises a main body having an opening on the upper surface and an outlet on one side, and a first belt conveyer disposed adjacent to the opening. A roller brush for contacting with the upper portion of the belt conveyor to prevent superposition of the substitute coins for alignment is arranged, and a second belt conveyor for receiving the aligned substitute coins is arranged at the lower portion of the first belt conveyor. The cleaning nozzle is arranged at the base end, the first cleaning brush is arranged at the upper part, the third belt conveyor is arranged at the lower part of the second belt conveyor, and the second cleaning brush is arranged at the tip and the wiping roller is arranged at the upper part of the belt conveyor. Then, a swing shooter is arranged below the wiping roller, a lamp heater is arranged above the swing shooter, and a fourth belt conveyor is arranged below the swing shooter. While aligning the tip of the muffler with the discharge port, a cleaning tank is arranged in the main body and connected to the cleaning nozzle via a pump, and further, a drain pan for collecting the wiped cleaning liquid is wiped with a cleaning roller and a cleaning tank. It is characterized in that it is placed between.

[0006]

[Operation] Put a substitute coin on a wide belt conveyor and move the coins on the belt conveyor without overlapping each other. During the moving process, washing, turning the front and back of coins, washing, wiping off water , Drying on a belt conveyor.

[0007]

According to the present invention, since the substitute coins are washed and dried on the wide belt conveyor, it is possible to process a large number of substitute coins at a time, and the processing ability is improved. Not only is it significantly improved, but the front and back of the coin can be reliably cleaned, and the cleaning effect is also improved. or,
Water is wiped off prior to drying, and then dried with a lamp heater, so that the drying effect is high.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail below with reference to the drawings. In the figure, (1) is a main body of the washing machine, which has a substantially rectangular box shape, and a caster (2) is attached to a lower part thereof. A substitute coin slot (3) is opened on the upper surface of the main body (1), and a discharge port (4) for discharging the washed substitute coin is opened on the lower part of one side surface. (5) is
This is a container for storing the substitute coin (6) discharged from the discharge port (4).

Referring to FIG. 2, the substitute coin (6) inserted from the insertion slot (3) is brought into contact with the wide first belt conveyor (7) and the upper portion of the first belt conveyor (7). The arranged roller brushes (8) arrange the substitute coins on the conveyor (7) so as not to overlap each other. The first belt conveyor (7) is arranged so as to slightly rise in the feeding direction so that the coins can be reliably aligned. Substitute coins aligned on the first belt conveyor (7)
(6) is fed to the second belt conveyor (9) arranged below it via the guide plate (10),
(9) Can be placed on top. The cleaning nozzle (11) is arranged at the base end of the second belt conveyor (9),
The cleaning liquid is sprayed on the substitute coin (6) above. The substitute coin (6) sprayed with the cleaning liquid is the second belt conveyor (9).
First, the upper surface of the belt conveyor is cleaned by the first cleaning brush (12) arranged on the upper end side of the belt conveyor. The washed substitute coin (6) drops from the tip of the second belt conveyor (9), and as shown in FIG.
The third belt conveyor (1
3) The front and back are placed upside down. While the third belt conveyor (13) is moving, the third belt conveyor (1
The other side of the coin substitute is washed by the second washing brush (14) arranged close to the upper part of (3). In this way, the substitute coins (6) whose front and back surfaces have been washed are paired with a pair of upper and lower wiping rollers (1) arranged adjacent to the tip of the third belt conveyor (13).
It passes between 5) and the water is wiped off. The substitute coin (6) wiped off the water drops onto the swing shooter (16) arranged below the third belt conveyor (13), and the high heat lamp arranged above the swing shooter (16) while moving. It is dried by the heat of the heater (17). Dried substitute coins
(6) is sent to the discharge port (3) by the fourth belt conveyor (18) located below the swing shooter (16) and discharged.

The cleaning liquid wiped off by the wiping roller (15) falls on the drain pan (19) and is returned to the cleaning liquid tank (20). The cleaning nozzle (11) is connected to the cleaning liquid tank (20) arranged in the main body (1) via a pump (21), and the cleaning liquid is sent. Further, a detachable reserve container (22) is connected to the washing tank (20), so that the reduced washing liquid can be replenished.

As described above, according to this washing machine, the substitute coins (6) are moved in a large amount by the belt conveyor having a width, and the washing and drying of both sides of the coin are performed during the movement. The processing capacity has improved remarkably. In the illustrated embodiment, the cleaning capacity is 120,000 per hour.
It was a sheet.
