The control device 9 includes a circulation process 90 for circulating the cleaning water and a monitoring process 9 for monitoring whether the cleaning water is normally circulating.
Step 2 is performed. These processes 90 and 92 are performed while the power switch is turned on and the collection device 1 is operating.

First, as shown in FIG.
When the power switch is turned on, first, it is determined whether or not the water storage tank 52 is installed at a predetermined location by using the water storage tank sensor 51 (S1). If a negative determination is made in this determination (S1), an installation failure warning (S9).
Is performed, and the process 90 is once terminated.
Execute Step 2.

In S2, it is determined using the detection sensor 46 whether the water level of the cleaning water in the cleaning water reservoir 44 has reached the level at which the pump 50 can be driven. If a negative determination is made in this determination (S2), since the water pump 50 does not operate, the warning lamp 59 is turned on to give a warning (S9), and the process 90 is once ended. In this case, the cleaning water is directly added to the cleaning water reservoir 44, and then the process 90 is executed again.

When an affirmative determination is made in this determination (S2), the operation of the water pump 50 is started (S3), and monitoring of the water level of the washing water in the adjustment tank 54 using the water level monitoring sensor 54a is started. (S4). When the driving of the water pump 50 is started in S3, the washing water starts flowing into the water storage tank 52, and the washing water overflows from the water storage tank 52 and is supplied to the empty adjustment tank 54. In the adjustment tank 54, the cleaning water is supplied to the water discharging device 34 and the cleaning water starts to be stored. In S4, the level of the stored cleaning water is monitored. The water level at which the water level monitoring sensor 54a is installed is hereinafter referred to as a control water level.

If it is determined in S4 that the washing water has reached the control water level, the pump 50 is stopped (S5), and this time it is determined whether or not the washing water level has dropped below the control water level (S6). )I do. At this time, when the pump 50 is stopped, the washing water flows from the water storage tank 52 for a while, so that the level of the washing water in the adjustment tank 54 rises.
Eventually it begins to fall. When it is determined that the water level of the washing water is lower than the control water level, the water pump 50 is driven again (S3). At this time, even if the pump 50 starts to be driven, the cleaning water does not flow for a while.
Although the water level of the washing water in the inside falls, but when the washing water starts flowing in, the water level of the washing water exceeds the control water level, the pump 50 is stopped again, and the processing of S5 and S6 is performed. Repeat the process.

As described above, in the circulation processing 90, the pump 50 is driven and controlled so that the amount of the washing water stored in the adjustment tank 54 is maintained at a predetermined amount. During operation, the supply of the cleaning water to the water discharging device 34 is maintained, and the cleaning water is circulated.

Next, the monitoring process 92 will be described. The monitoring process 92 is a process that is constantly performed while the collection device 1 is operating. In this monitoring process 92, the cleaning water pool 4
The detection sensor 46 detects whether the water level of the washing water of No. 4 stores sufficient washing water to drive the pump 50.
(S10), and if an affirmative determination is made in this determination (S10), the leak prevention sensor 4 determines whether the amount of washing water added to the washing water reservoir 44 exceeds the amount that can be stored.
8 (S12). Further, this determination (S
If an affirmative determination is made in 12), next, the water level monitoring sensor 54a determines whether or not the washing water overflows from the adjustment tank 54 (S14).
The determination of 14 is repeated again.

On the other hand, if a negative determination is made in any one of S10 to S14, a warning is issued, the operations of the cleaning unit 3 and the cleaning water circulation unit 5 are stopped, and the processing 92 is terminated. The use of the washing water circulation unit installed in the recovery apparatus 1 configured and operated as described above has the following effects.

When the washing water circulation unit 5 of the present embodiment is used, the washing water can be supplied to the water discharging device 34 in a state where the water storage tank 52 is installed above the washing unit 3. The installation position of the washing unit 3 can be made lower than that of the installed conventional washing water circulation unit. As a result, the installation positions of the medal tank 7 and the medal counter 20 installed above the washing unit 3 can be lowered.

When the washing water circulating unit 5 of the present embodiment is used, sludge consisting of grit and coin swarf is settled in the water storage tank 52, and the washing water overflowing from the water storage tank 52, that is, the supernatant washing water is circulated. As a result, it is possible to circulate cleaning water with little contamination.

In the washing water circulating unit 5 of the present embodiment, even if the pumping capacity slightly changes due to clogging of the bellows pipe 56, etc., the water level of the washing water in the adjusting tank 54 is kept constant. The supply of cleaning water to the tool 34 can be maintained. Further, in the washing water circulation unit 5 of the present embodiment, the pump 50 having a different pumping capacity can be used without performing special control.

In the washing water circulation unit 5 of the present embodiment, by removing the water storage tank 52 from the recovery device 1, the dirty washing water can be easily replaced. In addition, since the cleaning water is stored in the water storage tank 52 in a full state, the cleaning water can be efficiently exchanged. Further, in the present embodiment, since it is monitored whether or not the water storage tank 52 is properly installed in the recovery device 1, when the water storage tank 52 is not installed, the pump 50 is operated to clean the bellows pipe 56 and the like. Water can be prevented from being accidentally discharged.

The washing water circulation unit 5 of the present embodiment comprises:
The washing water reservoir 44 that can store the washing water in an amount that can be driven by the water pump 50 may be provided below the washing unit 3, so that the washing unit can be installed at a lower position than the conventional washing water circulation unit.

In the washing water circulation unit 5 of the present embodiment, the filtration filter 42 is provided at the most upstream part of the water conduit, and if the filtration filter 42 that is lighter and easier to handle than the washing water is replaced, the washing water is used for a long time. Therefore, the exchange cycle of the washing water can be shortened. Further, it is possible to effectively prevent the washing water reservoir 44 and the bellows hose 56 from being clogged.

The water storage tank 52 of the conventional cleaning water circulation unit requires troublesome work of detaching and connecting the water guide pipe and the signal line of the sensor from the water storage tank when replacing the cleaning water.
Moreover, since this work is performed by an ordinary pachinko hall employee, there is a risk that the water pipe and the signal line may not be correctly connected. However, in this embodiment, the bellows hose 56 and the signal line are directly connected to the water storage tank 52. There is no need for such troublesome work.

It should be noted that the embodiments of the present invention are not limited to the above-described embodiments at all, and it goes without saying that various forms can be adopted as long as they fall within the technical scope of the present invention. In addition, the circulation processing 90 performed by the control device 9 of the present embodiment corresponds to the water storage amount control means of the present invention.
