It is desirable that a shielding plate is provided to block the In this way, the shielding plate prevents the mist collector from sucking falling water or steam from the tank.

The cleaning chamber has first and second pipes to which the first and second nozzle groups are connected, and 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 movement (swaying) of the cleaning chamber is reduced.

It is desirable that the plurality of nozzles be detachably attached to each of the pipes. In this way, the nozzle can be replaced along with the piping according to the type of the object to be washed, eliminating the need to attach multiple types of nozzles so that the object can be washed regardless of the type of object to be washed, thus saving the cleaning liquid and air. can also reduce noise.

It is desirable that a water baffle 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 portions of the left and right chamber members, it is avoided that it comes out vigorously and splashes on the operator.

It is preferable that the apparatus frame has an opening formed on the front side through which the object to be cleaned is attached and detached, and that the opening is slanted so as to be located rearward as it goes upward. In this way, when the worker leans forward for attachment/detachment, the worker's head does not hit the device.

It is desirable that the left and right chamber members can be opened and closed separately. In this way, one can be closed for operation and the other can be opened to insert a hand to adjust the nozzle aim.

The cleaning chamber is desirably 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.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments according to the present invention will be described based on the drawings, but the present invention is not limited to the embodiments. In particular, the number and arrangement of nozzles, the shape of each member, and the like in the embodiment are examples, and the present invention is not limited to them.

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

It is a figure showing a schematic structure of a washing device concerning one embodiment of the present invention. As shown in FIGS. 1 to 3, the washing apparatus 1 includes a washing pump 3, a liquid heating heater 4, a drawer drainboard 5, a float switch 6 (see FIG. 12), and a chamber opening/closing air cylinder 7A. , 7B, a chamber moving air cylinder 8, a table rotating motor (rotating mechanism) 9, a mist collector 10, a line filter 11, an oil skimmer 12, a signal tower (alarm indicator) 13, and a light curtain 14 are attached.

Note that the cleaning device 1 has a small width and depth to save space, and the operation of the cleaning device 1 is performed by the pendant-type operation tool 15, which is more convenient than the case of using a box-type operation panel. We are trying to save space. A detection sensor is attached to the front side and upper part of the device frame 2 where the object to be washed is loaded, and when the operator inserts his hand while the device is operating, the detection sensor The safety is improved by detecting and emergencyly stopping the device 1 .

The apparatus frame 2 supports the cleaning chamber 16 and has an opening 2A formed on the front side through which the object to be cleaned is removed. A frame member 2Aa that forms the opening 2A is slanted so that the upper side is positioned more rearward. As a result, the head of the worker does not hit the device 1 when the worker leans forward for attachment and detachment, for example. Since a cover is provided around the table rotating motor 9, safety is ensured and the appearance is good.

Also, the size of the drawer drainboard 5 is increased to lengthen the cleaning cycle. Furthermore, although not specifically illustrated, flexible hoses and tubes are used instead of pipes for piping to secure a space above the collection tank. Therefore, at the time of maintenance, it is easy to perform work such as filter replacement and tank cleaning.

Moreover, since the overall height of the cleaning device 1 is low, the inside of the installation site such as a factory can be overlooked from above the cleaning device 1. - 特許庁Therefore, for example, the alarm indicator 13 of the cleaning device 1 placed in the back can be seen without fail.

4 is an enlarged side view of the vicinity of the cleaning chamber, FIG. 5 is a top plan view of the vicinity of the cleaning chamber, and FIG. 6 is a diagram 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 below a rotary table 44, which will be described later. The cleaning chamber 16 includes a tubular portion 22 having a bottomed tubular shape whose top is covered. The bottom member 21 has an inclined portion 21a for receiving liquid leaking from the cleaning chamber 16, and a base 24 is arranged under the inclined portion 21a. The inclined portion 21a is inclined downward from the peripheral edge toward the opening 24a. Since the collection tank 23 has a small capacity, the liquid heating heater 4 can 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. When they are closed, the portion that covers the upper portion of the cylindrical portion that is open at the bottom serves as a dome-shaped (hemispherical) ceiling portion. It's becoming As shown in FIG. 4, the cleaning chamber 16 is supported by a cam follower mechanism so as to prevent the cleaning chamber 16 from dropping under its own weight. The cam follower mechanism includes a shaft attachment plate 34 to which the rear portions of the chamber members 22A and 22B are rotatably attached via a plurality of hinges 32, and a shaft attachment plate 34 extending rearward from the apparatus frame 2 vertically. support shafts 17 supported so as to be slidable in parallel with each other, vertical members 18 attached to each support shaft 17 so as to extend in the vertical direction, cam rollers 19 rotatably provided at the lower ends of the vertical members 18, A guide rail 20 is provided on the device frame 2 and on which the cam roller 19 is movable. Thus, the cleaning chamber 16 is supported by the apparatus frame 2 via a cam follower mechanism including a support shaft 17 that advances and retracts together with the cleaning chamber 16 when the cleaning chamber 16 advances and retracts. The support shaft 17 and the guide rail 20 extend in the direction in which the chamber members 22A and 22B move for opening and closing, and the chamber members 22A and 22B move stably for opening and closing.

The cylindrical portion 22 is provided with a left chamber member 22A and a right chamber member 22B that are divided into left and right. The chamber members 22A and 22B are rotatably supported on a shaft mounting plate 34 at their rear portions so that the front portions can be opened apart from each other. 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) covering the periphery of the rotary table 44 (object to be cleaned) and the left and right chamber members 22A and 22B are separated. It is made movable between a rear side position (detachment position) in which it is rotated to an open state to open and expose the periphery of the rotary table 44 (object to be washed). In addition, since the cover around the cleaning chamber 16 is made of a transparent material, the visibility is good and it is easy to attach and detach the object to be cleaned.

Further, the left and right chamber members 22A, 22B are configured so that the front side portions (front side portions) thereof are opened and closed to the left and right by the chamber opening/closing air cylinders 7A, 7B. In addition, in the front portion of the cleaning chamber 16, a rubber packing 28 (buffer member) is provided between the front portions of the left and right chamber members 22A and 22B for adjusting the degree of closing (sealing property) of the left and right chamber members 22A and 22B. , so as not to be closed more strongly than necessary.

Therefore, the suction of the mist collector 10 sucking steam from the duct 25 for flowing the liquid from the cleaning chamber 16 to the recovery tank 23 reduces the air pressure in the cleaning chamber 16 and prevents the packing 29 between the front portions from being crushed. A water shielding plate 26A for blocking water falling from the mist collector 10 and a shielding plate 26B for blocking leakage of steam from the collection tank 23 are provided in the middle of the duct 25 (see FIG. 7).

The left and right chamber members 22A and 22B have circular windows 22Aa and 22Ba so that the inside of the cleaning chamber 16 can be observed. As shown in FIG. , 22Bb are formed with slant grooves (only slant groove 22Ad is shown) for preventing water from accumulating so as to extend in the thickness direction of the window frame. A water baffle plate 27 is provided between the front 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 parts of the left and right chamber members 22A and 22B, it is stopped by the water baffle plate 27 and does not come out vigorously, thus avoiding splashing on the operator.

When the cleaning chamber 16 is at the front position (cleaning position), the left and right chamber members 22A and 22B are closed to cover the rotary table 44 (object to be cleaned). Therefore, the object to be washed can be washed or drained and dried. For example, when an object to be cleaned is attached or detached, the cleaning chamber 16 (the left and right chamber members 22A and 22B) is opened by the chamber moving air cylinder 8 while the left and right chamber members 22A and 22B are opened by the chamber opening/closing air cylinders 7A and 7B. Move to 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 slidably supported by the apparatus frame 2, the chamber member 22A and 22B are stably moved for opening and closing.
When it moves from the front position to the rear position (removal position), the left and right chamber members 22A and 22B are opened to the left and right, and the remaining rotary table 44 (object to be washed) is opened. 44 (object to be washed) is exposed. Therefore, it becomes possible to easily attach and detach the object to be cleaned. Water supply ports 22Ac and 22Bc to which water supply pipes (not shown) are connected are provided in the upper portions of 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 are of low power, even if a worker's hand or the like is caught between the left and right chamber members 22A and 22B, the operator 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.

As a result, one chamber member is closed while the other chamber member is opened, and an operator puts his or her hand into the target direction of each nozzle of the first and second nozzle groups 31A and 31B to be described later. can be adjusted. In addition, since the inner volume of the washing chamber 16 is made small, the mist collector 10 can quickly suck the steam, and the drying performance is improved.

In addition, since there are a plurality of hinges 32 for supporting the chamber members 22A and 22B so that they can be opened and closed, the operation of replacing the hinges 32 can be facilitated. In other words, if there is only one hinge, the cleaning chamber 16 (chamber members 22A and 22B) itself will also come off when the hinge is removed. Such troublesome mounting work can be avoided by using a plurality of .

Further, inside the respective chamber members 22A, 22B, as shown in FIG. 8, first and second nozzle groups 31A, 31B are separately attached. The inner surfaces of the cleaning chambers 22A and 22B are provided with first and second nozzle groups 31A and 31B as well as first and second pipes 33A and 33B to which they are connected. , 33B are connected to the water supply ports 22Ac and 22Bc at their base portions, and are fixed to the left and right chamber members 22A and 22B at their tip portions, which are free ends, via fixtures. The first and second nozzle groups 1A, 31B are detachably attached to each of the first and second pipes 33A, 33B.

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

Also, the first and second nozzle groups 31A, 31B of the left and right chamber members 22A, 22B are arranged so as to face each other across the object to be cleaned. As a result, the cleaning liquid is sprayed from both the left and right sides of the object to be cleaned, so that the entire object to be cleaned can be efficiently cleaned by rotating the object to be cleaned.

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

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

A jig 45 for holding an object to be cleaned is provided on the upper surface of the rotary table 44 . A space is formed between the object to be cleaned and the rotary table 44 when the object to be cleaned is held by the jig 45 . Due to this space, the cleaning liquid comes into contact with the lower surface of the object to be cleaned, and the air passes through to efficiently dry the object to be cleaned. The shape of the jig 45 is not particularly limited as long as a space is formed between the object to be cleaned and the rotary table 44 .

As shown in FIGS. 3, 10 and 11, a fixed-position stopping mechanism 50 for stopping the rotary table 44 at a fixed position in the rotational direction is provided outside the cleaning chamber 16 and includes the cleaning chamber 16 and the table rotation motor 9. is set between. In other words, the detected member 51 is attached to the rotation shaft 43 side, and the position detection sensor 52 for detecting it is attached to the frame 2 side via the bracket 53 .

A base end of a roller bracket 54 having a rotatable rotating roller 54a at its tip is attached to the rotating shaft 43, and an actuator 55 (for example, an air cylinder) rotates a tip fitting portion of a movable member 56 at a predetermined position. It is provided so as to be fittable to the roller 54a. When the rotary table 44 is to be stopped, the detected member 51 is detected by the position detection sensor 52, thereby controlling the rotation of the table rotating motor 9, and the rotary table 44 is stopped at a fixed position in the rotation direction. will be made. At the time of this stop, the actuator 55 moves the movable member 56 so that its leading end fitting portion is fitted to the rotating roller 54a. This fitting allows the rotary table 44 to be reliably stopped at a fixed position in the rotation direction via the roller bracket 54 .

2. About washing/drying process 2-1. Cleaning Step In order to set the object to be cleaned in the cleaning device 1, the cleaning chamber 16 is positioned at the rear side, and the left and right chamber members 22A and 22B are opened to expose the inside of the cleaning chamber 16. An object can be attached to a jig 45 on a rotary table 44 . After the attachment is completed, the cleaning chamber 16 is positioned at the front side, the left and right chamber members 22A and 22B are closed, and the cleaning chamber 16 is made into a closed space. In this state, it becomes a washable state.

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

After washing the object to be washed for a predetermined period of time, jetting from the first and second nozzle groups 31A and 31B is stopped, and the next drying process is started. 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 rotating motor 9 is activated to rotate the rotating table 44 at high speed, and the compressor is activated. Then, the high-humidity air in the cleaning chamber 16 after cleaning is exhausted through the exhaust duct.

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

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

Then, it exits below the cleaning chamber 16 through the opening 24a. Air exiting the opening 24a is exhausted through an exhaust duct.

After draining and drying the object to be washed for a predetermined time, rotation of the compressor and the rotary table 44 is stopped. Then, the cleaning chamber 16 is moved to the rear side position (detachment 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. Thus, cleaning and drying of the object to be cleaned is completed.

2-3. Modification When adding an air nozzle that injects air to a plurality of nozzles, it is possible to accelerate the drying of the object to be cleaned by injecting air from the air nozzle in the drying process.

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