BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary dewatering device such as a washing machine and a coating device.

[0002]

2. Description of the Related Art
As a rotary dewatering device of this type, there is a coating device as shown in FIG. 7, for example.

The structure will be briefly described. A rotary shaft 51 is rotatably erected in the center of the bottom of the receiver 50 via a bearing 57, and the coating liquid b is stored in the bottom of the receiver 50. A donut-shaped container 52 is provided by a lifting mechanism 53 such as a hydraulic cylinder so as to be movable up and down while avoiding the rotating shaft 51, and a donut-shaped container 52 is set at the upper end of the rotating shaft 51 to a size that can be stored in the container 52. A basket 54 is rotatably provided in the upper part inside the receiver 50 by supporting and fixing the center of the basket 54, and a transmission belt 55 is wound around the lower end of the rotary shaft 51. A rotary drive source 56 that rotationally drives the transmission belt 55 is provided on the lower side of the receiving body 50.

Therefore, when a work (object to be coated) is stored in the basket 54 and the container 52 is raised by the elevating mechanism 53, the basket 54 is stored in the container 52. , The work in the basket 54 is the coating liquid b in the container 52.
Then, the container 52 is lowered, the rotary drive source 56 is operated and the basket 54 is rotated, and the extra coating liquid b permeating into the work is generated by the rotating centrifugal force. It is a structure that will be dehydrated.

However, a conventional rotary dehydrator such as this coating apparatus has a structure in which the center of the basket 54 is supported and fixed only by one point of the rotary shaft 51 which is erected at the center of the bottom of the receiver 50. Therefore, there is a drawback that the load resistance is slightly inferior.

In addition, because of the structure in which the center of the basket 54 is supported by the upper end of the rotary shaft 51, the basket 54 is affected by the uneven weight distribution of the works stored in the basket 54.
Is likely to cause large rotational shake when rotating. Therefore, since the bearing 57 of the rotary shaft 51 is heavily burdened by the rotational shake when the basket 54 rotates, there is also a problem that the bearing 57 is easily rattled and a failure is caused. There was a problem of poor sex.

The present invention has found out such problems and

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of the present invention (how to carry out the invention) will be briefly described with reference to the drawings and showing its function and effect.

When a large number of washed works a and works a soaked in the coating liquid b are stored in the rotary drum 2 and the rotary drive source 5 is operated, the transmission belt 4 is rotationally driven and the transmission belt 4 is rotated around the outer circumference. The rotating drum 2 wound around the rotating drum 2 rotates, and the cleaning liquid b permeating the work a stored in the rotating drum 2
The coating liquid b is dehydrated by this rotating centrifugal force.

At this time, unlike the conventional example, the basket 54 is not supported and fixed to the rotating shaft 51 standing upright in the center of the receiving body 50.
The rotary drum 2 is rotatably supported in the receiving body 3, and the transmission belt 4 from the rotary drive source 5 is wound around the outer circumference of the rotary drum 2. The bearing strength against the body 3 is high, and the load resistance is excellent, and it is not easily affected by the uneven weight distribution of the work a stored in the rotary drum 2. As described above, a large rotational blur does not occur.

Therefore, the bearing strength of the rotary drum 2 is high and the load bearing property is excellent, and since the rotary drum 2 is less prone to rotational shake, it is less likely to fail and has excellent durability.

According to the second aspect of the invention, since the transmission belt 4 which is rotationally driven by the rotary drive source 5 is wound around the rotary drum 2 in a horizontal state, the rotational operation of the transmission belt 4 is resisted. This is unlikely to occur, and the power transmission operation by the transmission belt 4 to the rotary drum 2 is performed better.

According to the third aspect of the present invention, the basket body 1 containing a large number of works a is housed in the rotary drum 2, and the container 6 is raised so that the rotary drum 2 is housed in the container 6. Then, the work a in the rotary drum 2 is dipped in the cleaning liquid b or the coating liquid b in the container 6 to be cleaned or coated.

Thereafter, when the container 6 is lowered and the rotary drive source 5 is operated, the transmission belt 4 is rotationally driven, and the rotary drum 2 having the transmission belt 4 wound around the outer periphery is rotated,
The cleaning liquid b and the coating liquid b that have permeated the work a in the basket 1 stored in the rotating drum 2 are dehydrated by the rotating centrifugal force.

Further, at this time, since the entire outer circumference of the rotary drum 2 is rotatably supported in the receiving body 3, the rotary operation of the rotary drum 2 can be more favorably performed, and the rotary drum 2 is also rotatably operated. Since the entire outer circumference of the bearing 2 is supported, the bearing strength of the rotary drum 2 with respect to the receiving member 3 is high, and the load resistance is excellent.

Further, since the cage body 1 for accommodating a large number of works a is accommodated in the rotary drum 2, a large number of works a can be taken in and out together with the cage body 1 from the rotary drum 2. The work of taking in and out can be performed very easily.

According to the fourth aspect of the invention, when the work a is housed in the rotary drum 2 and the pressure control mechanism 25 applies an external pressure to the cleaning liquid b and the coating liquid b in the container 6, the isolation container 23 The cleaning liquid b and the coating liquid b are introduced upward into the isolation container 23 above the container 6 through the communication passage 24 provided at the bottom of the
Further, the work a is introduced into the rotary drum 2 through a communication hole 16 provided in the rotary drum 2 housed in the isolation container 23, and the work a is immersed in the cleaning liquid b or the coating liquid b for cleaning or painting. The Rukoto.

Thereafter, the pressure control mechanism 25 causes the isolation container 23

It will be dehydrated by this rotating centrifugal force.

Therefore, since there is no vertical movement structure for the container 6 as in the third aspect of the invention, the height of the entire apparatus can be reduced and the size can be reduced, and the mechanical structure such as this vertical movement structure can be reduced. Since it does not have a structure that involves various operations, it has fewer failures and is more excellent in strength and durability.

As shown in FIG. 2, the three winding grooves 19 of the pulley 20 and the collar 14 of the upper part of the rotary drum 2 are provided. The mounting position of the pulley 20 is set so that the three winding grooves 15 are substantially flush with each other, and the three transmission belts are provided in the winding groove 19 of the pulley 20 and the winding groove 15 of the flange portion 14. 4 is wound in a horizontal state.

Therefore, since the three transmission belts 4 are wound in a horizontal state, the transmission belts 4 are

In the present embodiment, the rotary drive source 5 is constructed so as to be automatically operated after the above-mentioned coating operation is completed and the container 6 is lowered, and the rotary drum 2 is operated by the rotary drive source 5. Is rotated and the basket body 1 in the rotating drum 2 is rotated.
The extra coating liquid b permeating into the work a therein is dehydrated by the rotational centrifugal force of the rotary drum 2.

Therefore, in this embodiment, the coating operation of the work a stored in the basket 1 in the rotary drum 2 and the dehydration operation after coating are automatically performed by a series of operations. There is.

5 and 6 show a second embodiment of the present invention.

In this embodiment, a container 6 containing the coating liquid b is provided below the receiver 3, and the rotary drum 2 is provided above the container 6.
Is arranged in a storage state, a transmission belt 4 is wound around the outer circumference of the rotary drum 2, and a rotary drive source 5 for rotationally driving the transmission belt 4 is provided on the side of the receiving body 3 to An isolation container 23 for accommodating the upper rotary drum 2 is provided, and a communication passage 24 for communicating the inside of the isolation container 23 and the outside of the isolation container 23 is provided at the bottom of the isolation container 23, and a communication communicating with the communication passage 24 is provided. Hole 16
Is provided on the rotary drum 2, and a pressure control mechanism 25 for applying an external pressure to the coating liquid b outside the isolation container 23 is provided. When the external pressure is applied to the coating liquid b outside the isolation container 23 by this pressure control mechanism 25, The coating liquid b is introduced upward into the rotary drum 2 through the communication passage 24 and the communication hole 16.

As the rotary drum 2, the same one as that of the first embodiment is adopted, and the basket body 1 is detachably accommodated in the rotary drum 2.

The receiving body 3 is formed of a bottomed cylindrical body having an open upper portion, and a closing lid 7 is pivotally attached to the upper opening portion of the receiving body 3 so that the closing lid 7 can be undulated and opened and closed. Further, the lower portion of the receiving body 3 is formed in a cylindrical shape having a small diameter with a step, and the small diameter portion is configured as an isolation container 23 for accommodating the rotary drum 2.

The rotary drum 2 is rotatably supported around the entire inner upper portion of the receiver 3 in the same construction as in the first embodiment.

Further, similarly to the first embodiment, the rotary drive source 5 is attached to the upper side portion of the receiving body 3 via the mounting body 18 so as to project outward, and the pulley 20 of the rotary drive source 5 and the rotary drum 2 are attached.
The three transmission belts 4 are wound around the upper collar 14 so that all of them are in a horizontal state.

Further, the present embodiment illustrates the case where the entire circumference of the upper portion of the rotary drum 2 and the flange portion 14 are separately formed so that the rotary drum 2 can be detached from the receiving body 3.
Thus, the rotary drum 2 can be removed to easily clean and inspect the inside of the apparatus, and maintenance is facilitated.

The container 6 is formed by connecting a cylindrical body to the lower part of the receiving body 3, and as shown in the drawing, a U-shaped container void is formed on the outer peripheral surface and the bottom surface of the separating container 23. It is configured to be provided.

Further, a center portion of the bottom of the isolation container 23 is formed so as to penetrate therethrough, and a cylindrical body 27 having a predetermined length is penetrated through the through hole 26, and a locking flange 27 'at the upper end of the cylindrical body is formed through the through hole. The cylindrical body 27 is suspended from the bottom of the isolation container 23 in the state of being suspended from the hole edge of the container 26, and the vertically extending cylindrical body is used as the container 6.
It is configured as a communication passage 24 that communicates the inside with the inside of the isolation container 23.

Therefore, since the cylindrical body having a length is vertically provided in the container 6 from the bottom of the isolation container 23 to form the communication passage 24, for example, the coating liquid b contained in the container 6 is formed. Even if the amount of the liquid is small, the pressure control mechanism 25 can press the coating liquid b deeply downward by the length of the cylindrical body 27. Therefore, the coating liquid b can be raised into the isolation container 23 without any problem. You will be able to do it.

That is, as compared with the case where the communication passage 24 is simply formed by penetrating the bottom of the isolation container 23, the liquid level of the coating liquid b is normally between the bottom surface of the rotating drum 2 and the bottom surface of the isolation container 23. Therefore, it is not necessary to strictly adjust the amount of the liquid such as in the structure described above, and the liquid amount of the coating liquid b at the beginning of the structure can be set to be a little rough, so that the manufacturing becomes easier.

The pressure control mechanism 25 includes a regulating valve on the side of the container 6.
An air introducing pipe 28 provided with 29 is attached, and an air introducing device (not shown) is provided at the tip of the air introducing pipe 28. By operating this adjusting valve 29, air is introduced into the container 6. 6 is introduced, the coating liquid b in the container 6 is pressed downward due to the increased air pressure, escapes upward from the communication passage 24, and rises from the communication passage 24 into the isolation container 23. The adjustment valve 29 allows the volume 6
When the air inside is evacuated to reduce the air pressure, the coating liquid b is lowered from the inside of the isolation container 23 and stored in the container 6.

Therefore, since the air pressure is used, the air introducing pipe 28 having the adjusting valve 29 is simply attached to the container 6 as in the present embodiment, and an air flow device or the like is attached to the tip of the air introducing pipe 28. By providing the pressure control mechanism 25, the pressure control mechanism 25 can be configured very easily and the introduction cost is not required.

In this embodiment, when the operation of the pressure control mechanism 25 is completed and the work a in the rotary drum 2 is painted,
The rotary drive device 5 is automatically operated to perform the dehydration operation, and the coating operation of the work a as in the first embodiment,
The dewatering operation after painting is automatically performed by a series of operations.

Therefore, in the present embodiment, since the vertical movement mechanism such as the lifting / lowering device section 9 as in the first embodiment is not provided, the height of the entire device can be made low and compact, and this lifting / lowering device is also provided. Since it does not have a structure involving mechanical operation like the part 9, it has excellent strength and durability with few failures, and therefore has an excellent structure in which maintenance is very simple.

In the figure, reference numeral 30 is a liquid passage pipe that is connected to the side of the isolation container 23 to pass the coating liquid b inside the isolation container 23, and 31 is disposed in the liquid passage pipe 30. A detection rod body for detecting the liquid level that moves up and down along the liquid level in the liquid pipe 30.

Also, it is less likely to be affected by uneven weight distribution of the work stored in the basket, and this rotating drum does not cause a large rotational blur when rotating, unlike the conventional example, so it is less likely to cause a failure. As a whole, it becomes a revolutionary rotary dewatering device with extremely improved durability as compared with the conventional example.

Further, rather than a complicated structure having a rotary shaft as in the conventional example, a transmission belt is wound around a rotary drum rotatably supported by a receiver from a rotary drive source to rotate the rotary drum. The simple structure makes it easy to manufacture and mass-produced. In addition, even if it breaks down, it can be easily repaired, and as mentioned above, it is extremely easy to maintain because it is hard to break down. It becomes a rotary dehydrator that exhibits practical effects.

According to the second aspect of the invention, since the transmission belt which is rotationally driven by the rotary drive source is wound around the rotary drum in a horizontal state, the rotational operation of the transmission belt has a resistance. This is less likely to occur, and the power transmission operation to the rotary drum by this transmission belt will be performed even better.

According to the third aspect of the present invention, the basket body containing a large number of works is housed in the rotary drum, and the container is lifted to bring the rotary drum into the container. The work inside this rotary drum is immersed in the cleaning liquid or coating liquid inside the container for cleaning or painting, and then the container is lowered and the rotary drive source is operated, whereby the rotary drum rotates and Thus, it is possible to configure a rotary dewatering device in which the cleaning liquid and the coating liquid that have permeated the work in the basket housed in the drum are dewatered by the rotating centrifugal force.

Further, since the entire outer circumference of the rotating drum is rotatably supported in the receiving body, the rotating operation of the rotating drum is more favorably performed, and moreover, the entire outer circumference of the rotating drum is supported. Therefore, the rotary dewatering device has an excellent structure in which the bearing strength of the rotating drum against the receiver is high and the load bearing property is excellent.

Further, since the basket body for accommodating a large number of works is stored in the rotary drum, a large number of works can be taken in and out together with the basket body in the rotary drum. You can do it.

According to the fourth aspect of the invention, the work is housed in the rotary drum, and the pressure control mechanism applies an external pressure to the cleaning liquid and the coating liquid in the container, whereby the bottom portion of the container is isolated. The cleaning liquid and the coating liquid are introduced into the isolated container above the container via the communication passage provided in the above, and further introduced into the rotary drum through the communication hole provided in the rotary drum housed in the isolated container. Then, the work is immersed in this cleaning liquid or coating liquid to wash or paint, and then
By rotating the rotating drum by lowering the cleaning liquid or coating liquid in the isolation container from the isolation container by the pressure control mechanism, the cleaning liquid or coating liquid that has permeated the work stored in the rotating drum is rotated by this rotation. It is possible to configure a rotary dehydrator that is dehydrated by centrifugal force.

Therefore, since there is no vertical moving structure for the container as in the third aspect of the invention, the height of the entire apparatus can be reduced and the size can be reduced, and the mechanical structure such as the vertical moving structure can be achieved. Since it does not have a structure that involves operation, it has fewer failures, and therefore has excellent strength and durability, and has an excellent structure that makes maintenance easier.
