By doing so, the cleaning chamber is prevented from being lowered by its own weight because it is supported by the cam follower mechanism.

A bottom member is arranged below the rotary table and outside the cleaning chamber, and the bottom member has an inclined portion that returns the liquid leaking from the cleaning chamber to the rear side of the cleaning chamber. It is desirable that a base having an opening for returning the liquid leaked from the inclined portion to the recovery tank is arranged on the lower side. In this way, even if the liquid leaks from the inclined portion, it is collected in the collection tank through the opening of the base.

A fixed-position stop mechanism for stopping the rotary table at a fixed position in the rotation direction is provided, and the fixed-position stop mechanism is provided outside the cleaning chamber and between the cleaning chamber and the rotating mechanism. , Is desirable. In this way, since the fixed-position stop mechanism is outside the cleaning chamber, it does not interfere with the work inside the cleaning chamber or the injection from the nozzle.

In this case, the fixed position stop mechanism includes a member to be detected attached to the rotating shaft side, a position detection sensor attached to the device frame side to detect the member to be detected, and a base end portion attached to the rotating shaft. A roller bracket having a rotary roller at its tip and an actuator having a movable member and fitting a tip fitting portion of the movable member to the rotary roller are provided, and when the rotary table is stopped, the actuator is used. The movable member may be moved and the tip fitting portion thereof may be fitted to the rotating roller.

The mist collector sucks steam from the duct that allows the liquid to flow from the cleaning chamber to the recovery tank, and the water shield plate that blocks the water falling from the mist collector and the steam of the recovery tank leak to the duct. It is desirable that a shielding plate is provided to block the water. In this way, the shielding plate blocks the mist collector from sucking in the falling water and the steam in the tank.

The cleaning chamber has first and second pipes to which the first and second nozzle groups are connected, and the tip portions of the first and second pipes are fixed to the left and right chamber members, respectively. , Is desirable. In this way, the load applied to the base of the pipe due to the operation (sway) of the cleaning chamber is reduced.

It is desirable that the plurality of nozzles are detachably attached to each of the pipes. In this way, the nozzles can be replaced together with the piping depending on the type of object to be cleaned, and it is not necessary to install multiple types of nozzles so that cleaning can be performed regardless of the type of object to be cleaned, and cleaning liquid and air can be saved. , Noise can also be reduced.

It is desirable that a water shield extending from one of the left and right chamber members to the other is provided between the front portions of the left and right chamber members.

By doing so, even if water (hot water) leaks from between the front side portions of the left and right chamber members, it is avoided that the water (hot water) leaks vigorously and hits the operator.

It is desirable that the device frame has an opening formed on the front side on which the object to be cleaned is attached and detached, and the opening is obliquely inclined so as to be located rearward toward the upper side. In this way, the worker's head does not hit the device when the worker is in a forward leaning posture due to attachment / detachment.

It is desirable that the left and right chamber members can be opened and closed separately on the left and right. In this way, one can be closed to put it in operation, the other can be opened and a hand can be put in, and the aim of the nozzle can be adjusted.

It is desirable that the cleaning chamber is made of carbon fiber reinforced plastic. In this way, the appearance of the cleaning chamber can be improved, the cost can be reduced, and the weight can be reduced.

Hereinafter, embodiments according to the present invention will be described with reference to the drawings, but the present invention is not limited to the embodiments. In particular, the number and arrangement of nozzles in the embodiment, the shape of each member, and the like are examples, and the present invention is not limited thereto.

1. 1. Structure of the cleaning device FIG. 1 is a side view of the cleaning device according to the embodiment of the present invention, FIG. 2 is a front view of the cleaning device, and FIG. 3 is a view showing a rotating portion of the cleaning device.

It is a figure which shows the schematic structure of the cleaning apparatus which concerns on one Embodiment of this invention. As shown in FIGS. 1 to 3, the cleaning device 1 has a cleaning pump 3, a liquid heating heater-4, a drawer snorkel 5, a float switch 6 (see FIG. 12), and a chamber opening / closing air cylinder 7A in the device frame 2. , 7B, chamber moving air cylinder 8, table rotation motor (rotation mechanism) 9, mist collector 10, line filter 11, oil gap 12, signal tower (alarm indicator) 13, light curtain 14 are attached.

The width and depth of the cleaning device 1 are small to save space, and the cleaning device 1 is operated by the pendant type operation tool 15 as compared with the case where the box type operation panel is used. We are trying to save space. A detection sensor is attached to the front side of the device frame 2 and above it to load the object to be cleaned, and when the operator inserts a hand while the device is operating, the detection sensor detects it. By detecting and urgently stopping the device 1, the safety is improved.

The apparatus frame 2 supports the cleaning chamber 16 and has an opening 2A formed on the front side on which the object to be cleaned is attached and detached. The frame member 2Aa forming the opening 2A is inclined so as to be located rearward toward the upper side. As a result, for example, when the worker is in a forward leaning posture due to attachment / detachment, the worker's head does not hit the device 1. Since a cover is provided around the table rotation motor 9, safety is ensured and the appearance is good.

In addition, the drawer drainboard 5 is enlarged to lengthen the cleaning cycle. Further, although not specifically shown, a flexible hose or tube is frequently used for the pipe instead of the pipe to secure a space on the recovery tank. Therefore, it is easy to perform operations such as filter replacement and tank cleaning during maintenance.

Further, since the overall height of the cleaning device 1 is lowered, the inside of the installation place such as a factory can be seen from above the cleaning device 1. Therefore, for example, the alarm display 13 of the cleaning device 1 located in the back can be reliably seen.

FIG. 4 is an enlarged side view of the vicinity of the cleaning chamber, FIG. 5 is a plan view of the vicinity of the cleaning chamber as viewed from above, and FIG. 6 is a view showing a state in which the left and right chamber members of the cleaning chamber are opened.

As shown in FIGS. 4 and 5, the cleaning chamber 16 is made of carbon fiber reinforced plastic, and the bottom member 21 is arranged outside the cleaning chamber 16 and below the rotary table 44 described later. The cleaning chamber 16 includes a bottomed tubular tubular portion 22 whose upper surface is covered. The bottom member 21 has an inclined portion 21a that receives the liquid leaked from the cleaning chamber 16, and the base 24 is arranged below the inclined portion 21a. The inclined portion 21a is inclined downward from the peripheral edge toward the opening 24a. Since the recovery tank 23 has a small capacity, the liquid heating heater 4 may be small, which is advantageous in terms of cost reduction and energy saving.

The tubular portion 22 includes left and right chamber members 22A and 22B that can be opened and closed to the left and right, and when they are closed, a portion that covers the upper part of the cylindrical portion that opens downward is a dome-shaped (hemispherical) ceiling portion. It has become. Then, as shown in FIG. 4, the cleaning chamber 16 is supported by a cam follower mechanism to prevent the cleaning chamber 16 from being lowered by its own weight. The cam follower mechanism includes a shaft mounting plate 34 in which the rear portions of the chamber members 22A and 22B are rotatably attached via a plurality of hinges 32, and the cam follower mechanism extends rearward from the shaft mounting plate 34 and moves up and down to the device frame 2. A support shaft 17 supported so as to be slidable in parallel with the vertical member 18, a vertical member 18 attached to each support shaft 17 so as to extend in the vertical direction, and a cam roller 19 rotatably provided at the lower end of the vertical member 18. The device frame 2 is provided with a guide rail 20 on which the cam roller 19 can move. Therefore, the cleaning chamber 16 is supported by the device frame 2 via a cam follower mechanism including a support shaft 17 that advances and retreats together with the cleaning chamber 16 when the cleaning chamber 16 advances and retreats. The support shaft 17 and the guide rail 20 extend in the direction in which the chamber members 22A and 22B move to open and close, and the chamber members 22A and 22B are stably moved to open and close.

The tubular portion 22 includes a left chamber member 22A and a right chamber member 22B that are divided into left and right. The rear portions of the chamber members 22A and 22B are rotatably supported by the shaft mounting plate 34 so that the front portions can be opened so as to be separated from each other to the left and right. In the cleaning chamber 16, the left and right chamber members 22A and 22B are closed by the chamber moving air cylinder 8, and the front side position (cleaning position) that covers the periphery of the rotary table 44 (object to be cleaned) and the left and right chamber members 22A and 22B are It is in a state of being rotated and opened, and is movable between a rear position (detachable position) where the circumference of the rotary table 44 (object to be cleaned) is opened and exposed. Since the cover around the cleaning chamber 16 is made of a transparent material, the visibility is good and it is easy to perform the work of attaching and detaching the object to be cleaned.

Further, the front side portions (front side portions) of the left and right chamber members 22A and 22B are opened and closed left and right by the chamber opening and closing air cylinders 7A and 7B. In the front portion of the cleaning chamber 16, rubber packing 28 (buffer member) for adjusting the closing degree (sealing property) of the left and right chamber members 22A and 22B is provided between the front portions of the left and right chamber members 22A and 22B. , It is designed not to close more than necessary.

Therefore, the air pressure in the cleaning chamber 16 is lowered by the suction of the mist collector 10 that sucks steam from the duct 25 that flows the liquid from the cleaning chamber 16 to the recovery tank 23, and the packing 29 between the front side portions is prevented from being crushed. A water shield plate 26A that blocks water falling from the mist collector 10 and a shield plate 26B that blocks steam from the recovery tank 23 from leaking are provided in the middle of the duct 25 (see FIG. 7).

Further, the left and right chamber members 22A and 22B have circular window portions 22Aa and 22Ba so that the inside of the cleaning chamber 16 can be observed, and as shown in FIG. 8, an annular window frame 22Ab around the window portions 22Aa and 22Ba. , 22Bb is formed so that an inclined groove for preventing water accumulation (only the inclined groove 22Ad is shown) extends in the window frame thickness direction so as to prevent water from accumulating. Further, a water repellent plate 27 is provided between the front side portions of the left and right chamber members 22A and 22B (see FIG. 6). Even if water (hot water) tries to leak from between the front side portions of the left and right chamber members 22A and 22B, it is stopped by the drain plate 27, does not come out vigorously, and is prevented from being caught by the operator.

When the cleaning chamber 16 is in the front position (cleaning position), the left and right chamber members 22A and 22B are in a closed state and cover the periphery of the rotary table 44 (object to be cleaned). Therefore, the object to be cleaned can be washed or drained and dried. Then, for example, when attaching / detaching an object to be cleaned, the cleaning chamber 16 (left / right chamber members 22A, 22B) is opened by the chamber moving air cylinder 8 while the left and right chamber members 22A, 22B are opened by the chamber opening / closing air cylinders 7A, 7B. Move to the rear position. At this time, the cam roller 19 at the lower end of the vertical member 18 rolls on the guide rail 20, but since the support shaft 17 extending rearward from the shaft mounting plate 34 is supported by the device frame 2 so as to be slidable, the chamber member The movement of 22A and 22B for opening and closing is performed stably.
When the left and right chamber members 22A and 22B are opened to the left and right when the vehicle is moved from the front position to the rear position (detachable position), the periphery of the remaining rotary table 44 (object to be cleaned) is opened and the rotary table is opened. 44 (object to be cleaned) will be exposed. Therefore, the object to be cleaned can be easily attached and detached. Water supply ports 22Ac and 22Bc to which water supply pipes (not shown) are connected are provided above the chamber members 22A and 22B, respectively.

Since the chamber opening / closing cylinders 7A and 7B for opening and closing the left and right chamber members 22A and 22B have low power, even if an operator pinches his or her hand between the left and right chamber members 22A and 22B, he / she is less likely to be injured. There is. Since the chamber opening / closing cylinders 7A and 7B can be operated independently, the left and right chamber members 22A and 22B can be opened and closed separately on the left and right sides.

As a result, one chamber member is closed while the other chamber member is opened in the operating state, and the operator puts his / her hand in the target direction of each nozzle of the first and second nozzle groups 31A and 31B, which will be described later. Can be adjusted. Further, since the internal volume of the cleaning chamber 16 is reduced, the mist collector 10 sucks steam faster, and the drying performance is improved.

Further, since a plurality of hinges 32 that support the chamber members 22A and 22B so as to be openable and closable are provided, it becomes easy to perform work when exchanging the hinges 32 and the like. That is, if there is only one hinge, the cleaning chamber 16 (chamber members 22A and 22B) itself will be removed when the hinge is removed, so that it is necessary to reattach the cleaning chamber 16, but the hinge 32 By using a plurality of the above, such troublesome installation work can be avoided.

Further, as shown in FIG. 8, the first and second nozzle groups 31A and 31B are separately attached to the inside of the chamber members 22A and 22B, respectively. The inner surfaces of the cleaning chambers 22A and 22B are provided with first and second pipes 33A and 33B to which the first and second nozzle groups 31A and 31B are connected, and the first and second pipes 33A thereof are provided. Water supply ports 22Ac and 22Bc are connected to the root portions of the 33B, and the tip portions having free ends are fixed to the left and right chamber members 22A and 22B via attachments. The first and second nozzle groups 1A and 31B are detachably attached to each of the first and second pipes 33A and 33B.

The first and second nozzle groups 31A and 31B of the present embodiment use nozzles for injecting cleaning liquid, but two-fluid nozzles for injecting cleaning liquid and air may be used. Further, an air nozzle for injecting air may be added.

Further, the first and second nozzle groups 31A and 31B of the left and right chamber members 22A and 22B are arranged so as to substantially face each other with the object to be cleaned interposed therebetween. As a result, the cleaning liquid is sprayed from both the left and right sides of the object to be cleaned. Therefore, if the object to be cleaned is rotated, the entire object to be cleaned is efficiently cleaned.

On the other hand, below the cleaning chamber 16, a substrate 42 is provided with a chamber packing (not shown) and a tubular fixed chamber 41 interposed therebetween. Since the recovery tank 23 has a small capacity, the liquid heating heater 4 may be small, and since only one cleaning pump 3 is used as a pump, cost reduction and power consumption reduction can be achieved.

On the other hand, a circular opening 42a is formed in the center of the substrate 42 (see FIG. 12), and the rotation shaft 43 is inserted through the opening 42a. The lower end of the rotary shaft 43 is connected to a table rotary motor 9 that rotates the rotary shaft 43, and the upper end of the rotary shaft 43 penetrates the opening 42a and is connected to the rotary table 44 in the cleaning chamber 16. Therefore, the rotary table 44 rotates due to the rotation of the table rotary motor 9.

Further, a jig 45 for holding an object to be cleaned is provided on the upper surface of the rotary table 44. When the object to be cleaned is held by the jig 45, a space is formed between the object to be cleaned and the rotary table 44. With this space, the cleaning liquid hits the lower surface of the object to be cleaned, and air can pass through to efficiently dry the object to be cleaned. The shape of the jig 45 is not particularly limited, and a space may be formed between the object to be cleaned and the rotary table 44.

As shown in FIGS. 3, 10 and 11, the fixed position stop mechanism 50 for stopping the rotary table 44 at a fixed position in the rotation direction is outside the cleaning chamber 16, and the cleaning chamber 16 and the table rotation motor 9 are used. It is provided between. That is, the member 51 to be detected is attached to the rotation shaft 43 side, and the position detection sensor 52 for detecting the member 51 is attached to the frame 2 side via the bracket 53.

Further, the base end portion of the roller bracket 54 having the rotatable rotating roller 54a at the tip thereof is attached to the rotating shaft 43, and the tip fitting portion of the movable member 56 is rotated by the actuator 55 (for example, an air cylinder) at a predetermined position. It is provided so as to be fitted to the roller 54a. Then, when the rotary table 44 is stopped, the detected member 51 is detected by the position detection sensor 52, whereby the rotation of the table rotary motor 9 is controlled, and the rotary table 44 stops at a fixed position in the rotation direction. To be done. At the time of this stop, the movable member 56 is moved by the actuator 55, and the tip fitting portion thereof is fitted to the rotating roller 54a. By this fitting, the rotary table 44 can be reliably stopped at a fixed position in the rotation direction via the roller bracket 54.

2. Cleaning / drying process 2-1. Cleaning step By setting the cleaning chamber 16 to the rear side position in order to set the object to be cleaned in the cleaning device 1, the left and right chamber members 22A and 22B are opened and the inside of the cleaning chamber 16 is exposed. An object can be attached to the jig 45 on the rotary table 44. Then, after the installation is completed, the cleaning chamber 16 is set to the front side position, the left and right chamber members 22A and 22B are closed, and the cleaning chamber 16 is set as a closed space. In this state, it becomes a washable state.

The table rotation motor 9 is operated to rotate the rotary table 44, and the cleaning liquid is injected from the first and second nozzle groups 31A and 31B. As a result, the entire object is cleaned by the cleaning liquid while the object to be cleaned rotates together with the rotary table 44. At this time, the sprayed cleaning liquid passes through the rectangular opening 42b (see FIG. 12) formed behind the base 42 and is drained.

After cleaning the object to be cleaned for a predetermined time, the injection of the first and second nozzle groups 31A and 31B is stopped, and the process proceeds to the next drying step. A water circuit diagram showing the flow of water is shown in FIG. 13, and an air circuit diagram showing the flow of air is shown in FIG.

2-2. Drying step Next, the table rotary motor 9 is operated to rotate the rotary table 44 at high speed, and the compressor is operated. Then, the high-humidity air in the cleaning chamber 16 after cleaning is exhausted through the exhaust duct.

Further, since there is a space under the object to be cleaned with the rotary table 44, air enters this space and the lower surface of the object to be cleaned is also dried.

Then, the air to be cleaned and the air that has passed around the rotary table 44 flow toward the opening 24a of the base 24. At this time, an air vortex is formed below the rotary table 44, which further promotes drying of the lower surface of the object to be cleaned.

Then, it goes out from the opening 24a below the cleaning chamber 16. The air exiting the opening 24a is exhausted through the exhaust duct.

After draining and drying the object to be cleaned for a predetermined time, the compressor and the rotary table 44 are stopped from rotating. Then, the cleaning chamber 16 is moved to the rear side position (detachable position), the chamber members 22A and 22B are opened, the inside of the cleaning chamber 16 is exposed, and the object to be cleaned is removed. This completes the cleaning and drying of the object to be cleaned.

2-3. Modification example-When an air nozzle that injects air is added to a plurality of nozzles, air can be injected from the air nozzle in the drying step to accelerate the drying of the object to be cleaned.

-In the case of a cleaning device with a structure in which the blower and the intake port are connected via an intake duct, the air exhausted from the blower can be circulated in the cleaning chamber and reused for drying in the drying process. it can.
