First, the overall configuration of the cleaning apparatus 1 according to an embodiment of the present invention will be described.
As shown in FIG. 1 to FIG. 3, the cleaning apparatus 1 filters a cleaning unit 2 in which a workpiece 8 as a cleaning target is installed and cleaning is performed, and a used cleaning liquid that naturally flows down from the cleaning unit 2. A filter unit 3 that collects coarse solids, a dirty tank 4 that stores a cleaning liquid that naturally flows down from the filter unit 3, an oil-water separation tank 5 that removes oil floating in the cleaning liquid flowing in from the dirty tank 4, A clean tank 6 that stores the cleaning liquid after oil is removed by the oil / water separation tank 5 and a cleaning liquid pump 7 that reuses the cleaning liquid stored in the clean tank 6 and supplies the cleaning liquid 2 to the cleaning unit 2 and the like. ing.

As shown in FIGS. 1 to 3, the cleaning unit 2 is disposed at the uppermost part of the cleaning device 1, and the upper part is constituted by an open / close door 11 having a substantially rectangular shape in plan view, and the lower part is a plane communicating with the filter unit 3. The cleaning case 12 has a rectangular duct shape.
In this embodiment, the inner dimension of the edge 11a of the door 11 is formed in the cleaning case 12 in a rectangular shape that is slightly larger than the outer dimension, and the cleaning case 12 is closed with the door 11 closed. The upper end surface opening is configured to cover the opening / closing door 11 side without gaps. Thereby, even if cleaning liquid, air, etc. are injected inside cleaning part 2, cleaning liquid, air, etc. are prevented from leaking outside cleaning part 2. The opening / closing door 11 and the cleaning case 12 are connected by hinges 13 and 13 so that the opening / closing door 11 can be easily opened and closed by gripping and operating the handle 14. Furthermore, a viewing window 15, 15, 15 made of a transparent member is provided on the upper surface of the open / close door 11 to check the cleaning state in the cleaning unit 2 and whether the rotation of the workpiece 8 has stopped. It is configured as possible.

  Further, as shown in FIG. 3, a rotation support base 16 that supports the workpiece 8 rotatably in a horizontal plane is disposed inside the cleaning unit 2. The rotation support 16 is rotatably supported by a support member 27 fixed inside the cleaning unit 2. The rotation support base 16 includes a brake mechanism 18 described later.

The brake mechanism 18 will be described.
As shown in FIG. 4, a magnet-type first brake member 18a is fixed to the lower end of the support shaft 17 of the rotary support base 16. Further, a magnet-type second brake member 18b that is paired with the first brake member 18a is disposed below the first brake member 18a with a certain gap therebetween. The first brake member 18a and the second brake member 18b are composed of permanent magnets or the like that attract each other, and the first brake member 18a and the second brake member 18b are brought close to each other to generate a magnetic force that attracts the brake. It is set as the structure which produces an effect | action.

The second brake member 18b is connected to the link mechanism 19, and the second brake member 18b is displaced in the vertical direction in conjunction with opening / closing of the opening / closing door 11.
More specifically, when the door 11 is closed, the first link member 19a of the link mechanism 19 is pushed down by the door 11 and the second link member 19b is rotated clockwise in FIG. Accordingly, the second brake member 18b is displaced downward. At this time, the distance between the first brake member 18a and the second brake member 18b is set to a distance at which the braking action is eliminated, and the support shaft 17 can freely rotate.
On the other hand, when the opening / closing door is opened, the pressing of the first link member 19a by the opening / closing door 11 is released, and the first link member 19a biased by the spring 28 is lifted upward. At this time, the second link member 19b is rotated counterclockwise in FIG. 4, and accordingly, the second brake member 18b is displaced upward. At this time, the distance between the first brake member 18a and the second brake member 18b is set to a distance at which the brake action occurs by attracting each other, and the rotation of the support shaft 17 is restricted.
As described above, the brake is not applied when the door 11 is closed, and the brake is automatically applied when the door 11 is opened and the workpiece 8 is put in and out. The cleaning operation can be performed well and safely.
That is, when the cleaning unit 2 includes the brake mechanism 18 that stops the rotation of the workpiece 8, the efficiency of the cleaning operation can be improved.

Further, as shown in FIG. 3, cleaning liquid nozzles 20, 20... And air nozzles 21, 21. The cleaning liquid nozzles 20, 20... And the air nozzles 21, 21... Apply a rotational force to the work 8 when the cleaning liquid or air ejected from the nozzles 20, 21 contacts the work 8. It is set as the structure arrange | positioned at the angle to urge.
In this way, by adopting a configuration in which the workpiece 8 is rotated by the force of jetting the cleaning liquid or air, there is no need to separately provide a drive mechanism for rotating the workpiece 8, and the jet of cleaning liquid or air used for cleaning is discharged. Since it is not necessary to increase the pressure excessively, an increase in energy consumption can be suppressed.

As shown in FIG. 1 or FIG. 2, the filter unit 3 is arranged to communicate with the lower portion of the cleaning unit 2, and includes a filter case 22 formed in a duct shape having a substantially rectangular shape in plan view.
Further, inside the filter unit 3, a first funnel 23 having a substantially trapezoidal shape when viewed from the side, a second funnel 25 having a mesh filter 24 in the upper surface opening, and an approximately communicating with the discharge port 25 a of the second funnel 25. A cylindrical sock filter 26 is provided.
By adopting such a configuration, the used cleaning liquid flowing down from the cleaning unit 2 is first collected by the first funnel 23. Next, the cleaning liquid that naturally flows down from the discharge port 23a of the first funnel 23 flows down onto the mesh filter 24 and is filtered by the mesh filter 24 to remove coarse solids. Further, the cleaning liquid that has passed through the mesh filter 24 is collected by the second funnel 25 and naturally flows down from the discharge port 25a. The discharge port 25 a communicates with the sock filter 26 and is configured to collect fine solids that cannot be collected by the mesh filter 24 by the sock filter 26. Note that it is not necessary to completely remove the solid matter, and it is sufficient to remove the solid matter to the extent that there is no problem in the reuse of the cleaning liquid. In this example, the solid matter having a particle diameter of about 10 μm or more can be removed. The sock filter 26 is selected.

Below the filter unit 3, a tank is disposed, and the inside of the tank is divided by a partition plate to form three tanks (that is, a dirty tank 4, an oil / water separation tank 5 and a clean tank 6). Yes.
The dirty tank 4 is a substantially rectangular parallelepiped tank, and the upstream side communicates with the lower end side of the filter unit 3 and the downstream side communicates with the oil / water separation tank 5.
The cleaning liquid that naturally flows down from the filter unit 3 is dropped into the dirty tank 4 and stored. When the water level becomes a certain level or more, it overflows from the communication hole 30 formed in the partition plate on the downstream side of the dirty tank 4 so that the cleaning liquid flows into the adjacent oil / water separation tank 5. In the cleaning liquid, the oil component floats in the upper layer due to the difference in specific gravity, and the cleaning solution sinks in the lower layer, so that the oil and the cleaning solution are roughly separated while staying in the dirty tank 4.
That is, the filter unit 3 is disposed on a path that connects the cleaning unit 2 and the dirty tank 4. In other words, the filter unit 3 is connected between the cleaning unit 2 and the dirty tank 4. Yes. Thereby, it can be set as a compact apparatus structure. Moreover, a solid substance can be removed effectively.

As shown in FIG. 5 or FIG. 6, the oil / water separation tank 5 is a substantially rectangular parallelepiped tank, the upstream side communicates with the downstream side of the dirty tank 4, and the downstream side communicates with the clean tank 6. Further, each tank is constituted by successive tanks in the order of the inflow part 31 and the outflow part 32.
The oil / water separation tank 5 communicates with the dirty tank 4 through the communication hole 30, and the cleaning liquid overflowing from the dirty tank 4 first flows into the inflow portion 31.
As described above, since the cleaning liquid is roughly separated into the oil (upper layer) and the cleaning liquid (lower layer) in the dirty tank 4, the oil (upper layer) and the cleaning liquid (lower layer) are roughly separated also in the inflow portion 31. The state of being separated is maintained.

A partition wall 35 that divides the inflow portion 31 and the outflow portion 32 serves as a drill weir. Of the cleaning liquid that flows into the inflow portion 31, only the lower-layer cleaning liquid flows into the outflow portion 32. That is, out of the cleaning liquid that has flowed into the inflow portion 31, the oil contained in the cleaning liquid floats to the upper layer portion and is retained by the inflow portion 31, and only the cleaning liquid that has been separated from the oil water and has no oil content flows out. The configuration flows into the portion 32.
And the washing | cleaning liquid from which the oil component was removed flows out from the upper end open surface of the outflow piping 36 arrange | positioned in the outflow part 32. As shown in FIG.

As shown in FIGS. 5 to 7, an oil discharge port 37, which is a substantially rectangular opening, is formed on the side surface of the inflow portion 31, so that the oil retained in the upper layer portion of the inflow portion 31 can be discharged. It is said. The lower end height of the oil discharge port 37 is formed so as to be substantially the same as or slightly lower than the height of the upper end open surface of the outflow pipe 36. Only a certain amount is always discharged little by little to the oil recovery tank 38 side.
In addition, the oil discharge outlet 37 is provided with a discharge rod 39, and the oil component drops along the discharge rod 39 to the oil recovery tank 38.

Further, the air jetted to the cleaning unit 2 for cleaning and air blowing flows into the dirty tank 4, and the air sucked from the cleaning unit 2 is also introduced into the dirty tank 4 from the tapping 40 provided on the lid surface 4 a of the dirty tank 4. Is supplied to the inside, passed through the gap between the lid surface 4 a in the dirty tank 4 and the water surface, is flowed from the communication hole 30 to the oil / water separation tank 5, and is exhausted to the outside by the oil / water separation tank 5. It is configured.
Thus, the dirty tank 4 is configured such that the air ejected from the cleaning liquid nozzle 20 together with the cleaning liquid and the air ejected from the air nozzle are exhausted from the oil / water separation tank 5 disposed at the downstream end of the dirty tank 4. Since the upper layer (oil component) of the cleaning liquid is biased to flow toward the oil / water separation tank 5 in the downstream direction, the oil component can be actively collected in the oil / water separation tank 5. Thereby, the collection efficiency of oil can be improved.

Furthermore, a shutter 41 is disposed at the most upstream part of the oil / water separation tank 5.
When the cleaning apparatus 1 is in operation, the shutter 41 is raised so that the cleaning liquid flows from the dirty tank 4 to the oil / water separation tank 5. When the cleaning apparatus 1 is stopped, the shutter 41 is lowered. Thus, the oil once collected in the oil / water separation tank 5 does not return to the dirty tank 4 side.

  In addition, as shown in FIG. 12, it is also possible to form the flow path of the dirty tank 4 in a U-turn shape and arrange the oil / water separation tank 5 downstream thereof. By adopting such a configuration, the cleaning liquid in the dirty tank 4 is likely to stagnate and the separation action due to the difference in specific gravity can be promoted. Therefore, more effective oil / water separation can be performed in the oil / water separation tank 5. It becomes possible.

As shown in FIG. 7, the clean tank 6 is connected to the oil / water separation tank 5 on the upstream side by the outflow pipe 36, and the cleaning liquid from which solids and oil are removed flows in and is stored in the clean tank 6. It is said.
The cleaning liquid in the clean tank 6 is pumped up by the cleaning liquid pump 7 and supplied again to the cleaning liquid nozzle 20 of the cleaning unit 2 to be used for cleaning the workpiece 8. As described above, the cleaning liquid is configured to be circulated and used after removing impurities (solid matter and oil), and the amount of the cleaning liquid and water used can be reduced.
In the present embodiment, an air-driven diaphragm pump is employed as the cleaning liquid pump 7, and the cleaning liquid pump 7 is operated and stopped by controlling the supply and stop of air to the cleaning liquid pump 7. Yes.

Next, the cleaning liquid and air supply system of the cleaning apparatus 1 will be described.
FIG. 8 shows the air supply status in the initial state before the operation of the cleaning apparatus 1.
In this state, the air supplied from the air supply source 70 is supplied to the primary side of each of the start valve 51, the cleaning liquid valve 52, the blow air valve 53 and the suction valve 54.
Then, when the activation valve 51 is turned “ON” from the initial state shown in FIG. 8, the state transitions to the state shown in FIG.

FIG. 9 shows the supply state of air when the cleaning apparatus 1 is activated.
In this state, the start valve 51 is turned “ON” and at the same time, air can flow through the start valve 51, and the flow path of the first relay valve 55 is switched by this air pressure.
When the flow path of the first relay valve 55 is switched, air is supplied to the shuttle valves 63 and 64 so that the cleaning liquid valve 52 and the blow air valve 53 are turned on, and the cleaning liquid valve 52 and the blow air valve 53 are turned on. Air is supplied to the secondary side.

The blow air supply means 65 includes a blow air valve 53, a primary side pipe 66 that guides air supplied from the air supply source 70 to the blow air valve 53, and a secondary that guides air supplied from the blow air valve 53 to the air nozzle 21. A side pipe 67 is used.
When the blow air valve 53 is in the “ON” state, air is supplied to the secondary side of the blow air valve 53, and the air is supplied to the air nozzle 21 provided in the cleaning unit 2 of the cleaning device 1. It is configured.

When the flow path of the first relay valve 55 is switched, air is supplied to the shuttle valves 63 and 64, and at the same time, the cleaning liquid pump start valve 56 is turned on and the cleaning liquid pump 7 is started. The cleaning liquid stored in the clean tank 6 is pumped up and supplied to a pressure-increasing ejector 57 described later.
In addition, the air exhausted from the cleaning liquid pump 7 is supplied to the blowing nozzle 42 disposed in the oil / water separation tank 5, and the air is blown out from the upstream side to the downstream side of the oil / water separation tank 5. This prevents the oil collected in the oil / water separation tank 5 from returning to the dirty tank 4 side.

The cleaning liquid supply means 58 includes a cleaning liquid pump 7, a cleaning liquid valve 52, a pressure-increasing ejector 57, a primary pipe 68 that guides air supplied from the air supply source 70 to the cleaning liquid valve 52, and the cleaning liquid valve 52. A secondary side pipe 69 that guides the supplied air to the cleaning liquid nozzle 20, and the like. The pressure increasing ejector 57 is disposed on the secondary side pipe 69 of the cleaning liquid valve 52, and the discharge side of the cleaning liquid pump 7. The pipe is connected to the suction port side of the booster ejector 57.
In the pressure increasing ejector 57, the cleaning liquid supplied from the cleaning liquid pump 7 is sucked into the pressure increasing ejector 57 by the air pressure supplied via the cleaning liquid valve 52, and the cleaning liquid is supplied in the pressure increasing ejector 57. And the air are mixed, and the supply pressure of the cleaning liquid can be increased by passing through the pressure-increasing ejector 57.
The increased cleaning liquid is supplied to the cleaning liquid nozzle 20 provided in the cleaning unit 2 of the cleaning apparatus 1.
As described above, the cleaning liquid is ejected from the cleaning liquid nozzle 20 by the air supplied from the air supply source 70.

  At this time, air is also supplied to the shutter 41 provided in the oil / water separation tank 5 so that the shutter 41 is raised. As a result, the cleaning liquid in the dirty tank 4 can flow into the oil / water separation tank 5 through the communication hole 30.

  In this way, when the activation valve 51 is turned “ON”, the cleaning liquid pump 7 is started, and the cleaning liquid and air are respectively supplied to the cleaning liquid nozzle 20 and the air nozzle 21 in the cleaning unit 2, and the cleaning process of the workpiece 8 is started. It is assumed to be configured.

Furthermore, when the flow path of the first relay valve 55 is switched, air is supplied to the shuttle valves 63 and 64 and at the same time, air is supplied to the first time delay valve 59.
The first time delay valve 59 can be turned “ON” after a set time has elapsed since air was supplied, and the timer is started by supplying air to the first time delay valve 59. The cleaning process of the workpiece 8 is continued for a set fixed time after the valve is turned on until the valve is turned “ON”.
Then, when the first time delay valve 59 is turned “ON” from the cleaning state shown in FIG. 9, the state transitions to the state shown in FIG. 10.

FIG. 10 shows the air supply status after the first time delay valve 59 is activated.
In this state, when the first time delay valve 59 is in the “ON” state, air can flow through the first time delay valve 59, and the flow path of the second relay valve 60 is switched by this air pressure. .
When the flow path of the second relay valve 60 is switched, air is supplied to the shuttle valves 63 and 64 from the other port side, and the “ON” state of the cleaning liquid valve 52 and the blow air valve 53 is continued. Air is continuously supplied to the secondary side of the valve 52 for blow and the valve 53 for blow air. However, when the flow path of the second relay valve 60 is switched, the cleaning liquid pump start valve 56 is turned off and the cleaning liquid pump 7 is stopped. For this reason, in this state, only the air is ejected from the cleaning liquid nozzle 20.
As described above, the air blow process of the workpiece 8 is performed when the first time delay valve 59 is in the “ON” state.

That is, a rotation support base 16 that rotatably supports the work 8, a cleaning liquid nozzle 20 that ejects cleaning liquid, an air nozzle 21 that blows blow air, and a cleaning case 12 that houses the rotation support base 16, the cleaning liquid nozzle 20, and the air nozzle 21. A cleaning unit 2, a dirty tank 4 communicating with the downstream side of the cleaning unit 2, an oil / water separation tank 5 communicating with the downstream side of the dirty tank 4, and a downstream side of the oil / water separation tank 5. The cleaning apparatus 1 includes a clean tank 6 that communicates, a cleaning liquid supply unit 58 that supplies a cleaning liquid, and a blow air supply unit 65 that supplies the blow air. The air nozzle 21 is energized by blown air ejected from the air nozzle 21 and washed while rotating. Urged by blowing air to al ejected, it is dried while rotating, and a configuration.
Thereby, since the workpiece | work 8 rotates, the workpiece | work 8 can be wash | cleaned efficiently. Further, the work 8 is rotated by being energized by the jetting of cleaning liquid or air, so that unnecessary energy consumption due to the rotational drive does not occur.

Further, when the flow path of the second relay valve 60 is switched, the suction valve 54 is turned on, so that air is supplied to the secondary side of the suction valve 54.
A suction ejector 61 is disposed on the secondary side of the suction valve 54.
In the suction ejector 61, a suction action is generated by the air pressure supplied through the suction valve 54, and the suction ejector 61 communicates with the cleaning unit 2 of the cleaning device 1, whereby air is supplied from the cleaning unit 2. A configuration is possible in which suction is performed and the pressure inside the cleaning unit 2 can be reduced. Thereby, since the water | moisture content etc. which were scattered by air blow are collect | recovered, an air blow process can be performed efficiently.
The air discharged from the suction ejector 61 is supplied to the dirty tank 4.

Furthermore, air is supplied to the second time delay valve 62 at the same time as the flow path of the second relay valve 60 is switched.
The second time delay valve 62 can be turned “ON” after a set time has elapsed since air was supplied, and the timer is started when air is supplied to the second time delay valve 62. The air blow process of the workpiece 8 is continued for a set fixed time from when the state is reached until the valve is turned “ON”.
Then, when the second time delay valve 62 enters the “ON” state from the air blow state shown in FIG. 10, the state transitions to the state shown in FIG.

FIG. 11 shows the air supply status after the second time delay valve 62 is activated.
In this state, when the second time delay valve 62 is in the “ON” state, air can flow through the second time delay valve 62, and the flow path of the first relay valve 55 is switched by this air pressure. . Then, when the flow path of the first relay valve 55 is switched, the flow path of the second relay valve 60 is also switched to return to the initial state shown in FIG.
In this way, the second time delay valve 62 is turned “ON” so that a series of cleaning and air blowing steps of the cleaning device 1 are completed.

  That is, in the present invention, the cleaning liquid supply means 58 uses a drive source as air, and thus the control source and the operation panel are omitted by unifying the drive source of the cleaning device 1 and its auxiliary equipment into air. It can be done. In addition, this contributes to a reduction in the manufacturing cost of the cleaning device 1 and a compact device configuration.
