Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cleaning and drying industrial parts such as plating, electricity and machinery.

[0002]

2. Description of the Related Art Conventionally, oil and dirt adhered in the process of processing industrial parts are degreased with a solvent such as CFC or trichloroethane, an acid-based or alkaline-based cleaning agent, or rinsing water or pure water. It was cleaned by immersing the parts to be treated in the cleaning liquid tank. Furthermore, in order to activate the reaction with the degreasing cleaning liquid and enhance the cleaning power, a cleaning device with a rocking mechanism as shown in FIG. It was common to use a dedicated cleaning device provided. In the apparatus illustrated in FIG. 3, the casing 31 has a degreasing cleaning liquid and a rinsing liquid 3
2 is a device for immersing the basket 34 filled with the processing parts 33 in this liquid, and swinging the basket 34 in the vertical direction by the swinging mechanism 35. The swinging mechanism 35 improves the efficiency of removing oil and dirt. It was something to do. Further, for the drying treatment, the parts that have undergone the washing treatment are transported to a dedicated drying device and subjected to treatments such as a centrifugal method, a heat treatment furnace, hot air blowing, or vacuum drying.

Further, recently, a centrifugal washing and dehydrating machine having a mechanism similar to that of a domestic washing machine as shown in FIG. 4 has been announced, which is a liquid feeding mechanism 42 which feeds a casing 41 having a cover 48. Degreasing cleaning liquid or rinse liquid 4
3 is stored therein, and the basket 45 filled with the processing parts 44 is alternately rotated by the rotating mechanism 46 in both the forward and reverse directions to remove oil and dirt, and the electromagnetic valve 47 is opened and closed to discharge the drainage. Although the degreasing treatment can be performed by rotating the basket 45 at a high speed after draining the liquid, the drying function is not provided, and thus the drying cannot be performed sufficiently.

[0004]

As described above, since the conventional cleaning device and drying device are dedicated to cleaning and drying, respectively, both of these devices must be used together to perform the cleaning / drying process. An automatic transfer device or the like is required as a means for transferring the processed parts from the dryer to the drying device, which requires a large space and enormous cost for purchasing and maintaining the device. Also, when relying on manual transfer from the cleaning device to the drying device, at the end of the cleaning process, remove the processed parts from the cleaning device, carry them to the drying device, put the processed parts in the drying device, and process after the drying process. It took a great deal of effort and time to take out the parts.

Further, even in an apparatus for automatically performing a series of these processes, there is a drawback that a loss time occurs in transportation or the like in addition to the time actually required for the cleaning or drying process itself, and the processing time becomes long. In addition, with a cleaning method and cleaning device that does not require a drying step using a volatile solvent such as CFCs or trichloroethane, the above-mentioned time and labor are not required, but the entire surface is used for reasons such as ozone layer depletion. The ban has been decided, and there is a problem that the cleaning process will not be possible with CFCs and trichloroethane.

From the viewpoint of the effect of cleaning oil and dirt, in the case of cleaning by immersing the treated parts in a conventional degreasing cleaning liquid tank and applying mechanical vibrations or minute vibrations such as ultrasonic waves, Since there is no significant change in the position and orientation of the treated parts, the cleaning liquid deteriorated by the removal of oil and dirt is removed from the surroundings of the treated parts, and only the reaction with the degreasing cleaning liquid is activated, so the cleaning quality is degreased. It largely depended on the state of the cleaning liquid.

In the centrifugal cleaning degreasing system, the treated parts are
During rotation, the basket sticks to the circumference of the inner wall of the basket, and the amount of movement due to switching between the forward and reverse rotation directions is small, so the cleaning power is weak, and therefore the processing time becomes long.

Further, when the processing parts are taken out upward from the degreasing / cleaning liquid tank by the rocking system or the micro-vibration system, and when the degreasing / cleaning liquid is discharged from the lower part of the casing by the centrifugal cleaning / degreasing system, the degreasing / cleaning liquid is contained in the degreasing / cleaning liquid. The remaining oil, dirt, dust, and the like may adhere to the treated parts, causing problems such as stains and oil residue in the next drying step, which causes poor drying. The present invention aims to solve these problems mentioned above.

[0009]

According to the first aspect of the present invention, there is provided a basket for accommodating an object to be processed, which has a substantially cylindrical shape with a bottom and is provided with a large number of small holes, and the basket. A rotation mechanism that rotates the gears in a variable speed, a portion that stores the basket to store the degreasing cleaning liquid or the rinsing liquid, and a casing to which the rotation mechanism is attached, and the casing from an upright state to an inclined state. An inclined rollover mechanism to change, the casing is operated at a low speed in the inclined state to wash and rinse the object to be treated, and when the casing is upright, the rotating mechanism is operated at a speed higher than the speed. It is solved by operating and dehydrating and drying the object to be treated.

Further, according to the second aspect of the present invention, a basket for accommodating the object to be treated, accommodating the object to be treated, having a substantially bottomed cylindrical shape and having a large number of small holes, and the basket. A rotation mechanism that rotates in a variable speed, a portion that stores the basket and stores a degreasing cleaning liquid or a rinsing liquid, and a casing to which the rotation mechanism is attached, and a posture that the casing extends from an upright state to a downward inclined state. An inclined rollover mechanism for changing, the casing is operated at a low speed to wash and rinse the object to be treated when the casing is inclined, and the casing is operated at a higher speed than the speed when the casing is upright. The object to be treated is dehydrated and dried, and the object to be treated is taken out when the casing is inclined downward.

A basket for accommodating an object to be treated and having a substantially bottomed cylindrical shape and having a large number of small holes, a rotating mechanism for rotating the basket, and a basket for accommodating the degreasing cleaning liquid or rinsing liquid. Has a part, and
A casing to which the rotating mechanism is attached, a tilting and overturning mechanism for changing the posture of the casing to an inclined state, a drain mechanism provided near the peripheral portion of the bottom surface of the casing, and a feeding device for supplying a degreasing cleaning liquid and a rinsing liquid from above the casing. And a liquid mechanism, wherein the basket is rotated by the rotating mechanism in a tilted state of the casing to repeat the turning displacement of the object to be treated, and the degreasing of the object to be treated while supplying the degreasing cleaning liquid or the rinse liquid by the liquid feeding mechanism. This is solved by performing cleaning or rinsing and discharging the contaminated degreasing cleaning liquid and rinsing liquid by displacing the drain mechanism upward by tilting the casing and functioning as an overflow mechanism.

[0012]

With the basket and the rotating mechanism housed inside, the casing whose posture can be changed from the upright position to the downward tilt enables consistent work from cleaning to drying and removal without moving the processing parts. In the inclined state of the casing, the degreasing cleaning liquid and the rinsing liquid are poured from above to perform degreasing cleaning and rinsing, and when the casing is inclined, the drain mechanism is displaced and acts as an overflow mechanism.
The contaminated degreasing cleaning liquid rinsing liquid is discharged from the drain mechanism as an overflow mechanism to improve the cleaning effect.

1 and 2 show an embodiment of the present invention. Reference numeral 1 denotes a rotation mechanism, which is driven by a motor 1a and generates a low to high speed rotation output. Reference numeral 2 denotes a bottomed cylindrical basket formed of punching metal or the like, which is connected to the rotating shaft of the rotating mechanism 1 and accommodates a processing component 12 to be washed, rinsed, and dried. The rotation output of the rotating mechanism 1 is transmitted to the basket 2. Reference numeral 3 denotes a casing, which accommodates the rotating mechanism 1 and the basket 2, both of which are separated by a partition wall 3a and is divided into an upper portion 3b that accommodates the basket 2 and a lower portion 3c that accommodates the rotating mechanism 1. ing. Reference numeral 10 denotes a cover which is provided on the upper portion of the casing 3 and serves as a lid for the casing 2. The cover 10 is opened and closed by a cover opening / closing mechanism 11 as shown by an arrow A. The mechanism 11 opens the cover 10 from which the processing component 12 is placed in a basket. After being charged into the inside 2, the mechanism 1
Closed by 1.

Reference numeral 4 denotes a tilt-overturning mechanism, which includes motors 4a,
The motor 4 comprises a pinion 4b and a gear 4c.
The driving force of a is transmitted to the gear 4c via the pinion 4b, so that the casing 3 connected to the gear 4c is connected to the gear 4c.
The posture is changed by rotating it as indicated by arrows B and C. 6 is the bottom of the portion 3b of the casing 3, that is, the partition wall 3
The drain mechanism is provided at a, and its installation position is provided at a position where the position is changed upward when the casing 3 is tilted, in other words, near the periphery of the bottom surface.

A hot air generating mechanism 7 generates hot air for the drying process, and the hot air is blown into the interior of the casing 2 by a supply pipe 7a penetrating the cover 10. Reference numeral 5 denotes a liquid feeding mechanism, and the degreasing cleaning liquid and the rinsing liquid penetrate the cover 10 from above the casing 2
It is sent inside by a. The type of liquid is selected and delivered by a mechanism (not shown) according to the process. Although not shown in the figure, the liquid supply method can be selected from spraying, jetting, showering, etc. depending on the purpose.

Each of the above-mentioned mechanisms is attached to a base 9 of the entire apparatus via a vibration-proof mechanism 8 for preventing vibration generated by rotation.

FIG. 2 shows the state of the cleaning and rinsing process.
After the cleaning process, the drain mechanism 6 discharges the degreasing cleaning liquid, or the rinse liquid is supplied without discharging the cleaning liquid.
Although the rinsing step is performed, it is considered that the two basically differ only in the type of liquid to be used, and therefore the two will be collectively described here. The casing 3 is tilted by the tilting and overturning mechanism 4, and the degreasing cleaning liquid or the rinsing liquid 13 injected by the supply pipe 5a from the liquid feeding mechanism 5 attached to the cover 10 on the upper portion of the casing 3 is stored in the casing 3. It is stored in the upper part 3b. Since the drain mechanism 6 of this portion is displaced upward due to the inclination of the casing 3, the respective liquids are not discharged. In this state, the processing parts 12 contained in the basket 2 are treated with the degreasing cleaning liquid or the rinsing liquid 1.
Since it is rotated by the rotating mechanism 1 while being immersed in 3,
It repeatedly lifts up and then drops, so that its position and direction are frequently changed, and the processing parts rub against each other, so-called tampering is performed to remove oil and dirt adhering to the surface.

The removed oil and dirt are mixed in the degreasing cleaning liquid or the rinsing liquid 13, but flow in the centrifugal direction due to the rotation by the rotating mechanism 1, and a new clean fluid is constantly injected by the liquid feeding mechanism 5. The liquid or rinsing liquid raises the liquid level, and as the liquid level rises, oil and dirt are pushed up to the upper part of the liquid surface. As described above, since the drain mechanism 6 is provided at a position where it is displaced upward when the casing 3 is tilted, it operates as an overflow mechanism in the tilted state. Therefore, the contaminants pushed up to the upper portion of the liquid surface are prevented from being discharged to the outside of the casing 3 through the drain mechanism 6 as an overflow mechanism and reattached to the processing component 12.

After the washing and rinsing processes are completed as described above, the tilting and overturning mechanism 4 is operated to erect the casing 3 and the drying process is performed. The rotating mechanism 1 rotates at a higher speed than during cleaning and rinsing, and spins off due to the centrifugal effect.
Liquid removal processing such as deoiling is performed. In addition to this rotation,
Hot air from the hot air generating mechanism 7 is blown through the supply pipe 7a to promote drying.

After a series of processes including washing and rinsing and drying are automatically performed, the cover 10 having the lid on the upper portion of the casing 3 is opened by the cover opening / closing mechanism 11, and the casing 3 is rotated by the tilting and overturning mechanism 4. The casing 3 moves sideways until the opening of the casing 3 faces obliquely downward, and the processing component 12 filled in the basket 2 is automatically discharged to the outside.

In the above embodiment, the degreasing cleaning liquid and the rinsing liquid are configured to be supplied at room temperature. However, heaters are provided in the casing 3 and the liquid feeding mechanism 5 to inject the degreasing cleaning liquid and the rinse liquid. Activated by raising the temperature,
It is also possible to increase the speed of removing oil and dirt.

The degreasing cleaning liquid and the rinsing liquid, which are injected from the liquid feeding mechanism 5 through the supply pipe 5a, are sprayed,
Efficient results can also be obtained by supplying a shower type over a wide range. Furthermore, it is conceivable to add a flow rate adjusting mechanism such as a valve to the drain mechanism (overflow mechanism) 6.

A detailed description of the tilt roll mechanism 4 may be a known technique, for example, a gear mechanism illustrated in FIG.
Since hydraulics, pneumatic cylinders, chains, splots, etc. may be used, they are omitted.

[0024]

As described above, according to the first aspect of the present invention, the two devices, the cleaning device and the drying device, which are conventionally required for the degreasing cleaning and drying processes, can be completed in one device.
The installation space can be reduced by about 40%, and as a result, the running cost can be reduced and the cost of the product can be reduced. Furthermore, there is also an effect that the time and labor conventionally required for transporting the processing parts from the cleaning device to the drying device can be reduced to zero. Further, according to the second aspect of the present invention, in addition to the above effects, even the taking out of the processing parts can be automated. Then, according to the third aspect of the present invention, the cleaning effect can be obtained by frequently changing the position and orientation of the processing component, and activating the degreasing cleaning liquid that is agitated by rotation to improve the cleaning power. The rate of occurrence of poor drying due to stains and oil residue can be significantly reduced, and loss cost can be reduced. Furthermore, since neither CFCs nor trichloroethane is used, there is no concern about ozone layer depletion, which has become a problem in recent years, and CFCs and ethane can be used even after they have been completely abolished, which is also effective in terms of environmental protection.
