Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cleaning device, which cleans mechanical parts, electronic parts, medical instruments, and various other objects by liquid or steam cleaning. The purpose is to reliably dispose of the cleaning liquid that has adhered to the surface without spreading it to the outside.

BACKGROUND ART Conventionally, there is an idea described in Japanese Utility Model Publication No. 59-28714, in which a washing table on which an object to be washed is placed is connected to a moving mechanism so as to be movable. However, after the cleaning work has been completed, the cleaning object is taken out of the cleaning tank, and then the cleaning liquid adhering to the cleaning object is dried in a separate processing device. Moreover, there is no shielding plate for preventing the inflow of solvent gas between the cleaning section where the cleaning liquid is present and the entrance/exit for entering and exiting the object to be cleaned. Therefore, a large amount of solvent gas flows out when the object to be cleaned is taken in and taken out.

Moreover, since it does not have a drying means, not only does the drying process require a lot of effort, but it also comes into contact with the outside air when being transferred to the processing equipment. In this case, if the cleaning liquid is trichlorethylene, trichlorotrifluoroethane, etc., which is undesirable for diffusion into the atmosphere, it may cause health damage, air pollution, etc.

There is also an invention described in Japanese Patent Publication No. 59-9228, which is constructed so that the object to be cleaned, which has been completely cleaned and has cleaning liquid attached thereto, can be stored while being shielded from the cleaning section. However, this method is performed by an operation separate from the vertical movement of the object to be cleaned. Therefore, the mechanism is complicated, and if the timing of the vertical movement of the object to be cleaned and the timing of the shielding are out of sync, the solvent gas may leak out.

Problems to be Solved by the Invention The present invention aims to solve the above-mentioned problems. The aim is to dispose of it without requiring any effort and without dispersing harmful substances to the outside.

Means for Solving the Problems The present invention solves the above problems by:
By connecting the cleaning table on which the object to be cleaned is placed and making it movable in position, the object to be cleaned placed on the cleaning table is connected to the cleaning tank and the processing chamber and cleaning tank are installed. This processing chamber and the cleaning tank can be shielded by a shielding body, and this shielding body is pivotally supported on both sides of the lower surface of the cleaning table by support shafts so as to be freely openable and closable. An engaging portion is protruded outward, and this engaging portion can be engaged with the outer periphery of the communication port between the processing chamber and the cleaning tank when the object to be cleaned is stored in the processing chamber due to movement of the washing table, and by this engagement, A processing mechanism that is capable of shielding a processing chamber and a cleaning tank by rotating around a support shaft and sealing the shielding body, and is equipped with a processing chamber and activated carbon for removing cleaning liquid adhering to objects to be cleaned. are connected to each other by a communication path through which gas can flow, and a communication opening for communicating with outside air is opened in the processing chamber connected to this communication path.

Function Since the present invention is constructed as described above, in order to wash the object to be cleaned, the moving mechanism is activated, the washing table on which the object to be cleaned is placed is inserted into the washing tank, and the washing table with the object to be cleaned is inserted into the washing tank. , steam cleaning, etc.

After completion of this liquid cleaning and steam cleaning, the moving mechanism is operated again, and the object to be cleaned placed on the cleaning table is stored in a processing chamber connected to the cleaning tank. After this storage, or at the same time as the storage, the processing chamber and the cleaning tank are shielded by a shielding body, and a processing mechanism for removing the cleaning liquid adhering to the object to be cleaned is activated.

Since this processing mechanism is connected to the processing chamber through a communication path through which gas can flow, the gas in the processing chamber is introduced into the processing mechanism while being shielded from the inside of the cleaning tank. It becomes possible to process. Therefore, by introducing outside air through the communication opening, organic solvents and the like adhering to the object to be cleaned can be continuously fed into the processing mechanism, and the solvent can be removed until it is completely removed.

After this treatment, if the object to be cleaned is taken out of the treatment chamber, no harmful gases will be diffused into the atmosphere or inhaled by the operator, making it possible to carry out safe cleaning operations.

In addition, the object to be cleaned with the cleaning liquid attached to it is stored in the processing chamber from the cleaning tank without leaving the cleaning device and the adhered cleaning liquid is processed, so the object to be cleaned is not transferred to the processing mechanism as in the conventional case. Not only does it not require transportation, but it also does not cause the solvent to diffuse.

Further, since the processing chamber communicates with the processing mechanism while being shielded from the cleaning tank by the shielding body, excess solvent vapor is not sent to the processing mechanism, and processing efficiency can be improved.

Further, since the processing chamber and the shielding body are automatically shielded as the washing table is raised, the timing of the shielding is not disturbed and the mechanism can be simplified.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a washing table on which an object to be washed 2 is placed, and an appropriate moving mechanism 3 such as an air cylinder, an oil cylinder, or a chain device. It is connected to and is formed to be movable in the vertical direction. By operating a moving mechanism 3, this washing table 1 moves an object 2 placed on its upper surface back and forth between a processing chamber 4 and a washing tank 5, which are connected to the upper part of a washing tank 5. In addition to being movable, the processing chamber 4 and the cleaning tank 5 can be shielded by a shield 6.

In this shield, a pair of flat shields 6 are supported on both sides of the lower surface of the washing table 1 by support shafts 7 so as to be openable and closable. Furthermore, an engaging portion 8 protrudes outward from the support shaft 7. The engaging portion 8 is engaged with the outer periphery of the communication port 10 between the processing chamber 4 and the cleaning tank 5 when the object 2 to be cleaned is stored in the processing chamber 4 as the washing table 1 is moved.
By rotating around the support shaft 7 and sealing the shield 6, the processing chamber 4 and the cleaning tank 5 are shielded.

Further, in the communication port 10 between the cleaning tank 5 and the processing chamber 4, a lid 11 having no special fixing means is located on the processing chamber 4 side. This lid 11 closes the communication port 10 when the object 2 to be cleaned is located in the cleaning 5. When the washing table 1 is raised, the support rod 12 protruding from the upper surface of the washing table 1 lifts and opens the lid 11 as shown in FIG.

The processing chamber 4 also includes a processing mechanism 14 for removing the cleaning liquid 13 attached to the object 2 to be cleaned.
are connected by a communication path 15 through which gas can flow.

This processing mechanism 14 is equipped with activated carbon that can adsorb a solvent. Furthermore, the processing chamber 4 connected to the processing mechanism 14 via the communication path 15 is provided with a communication opening 17 for communicating with the outside air. will be introduced.

In the structure as described above, in order to perform liquid cleaning or steam cleaning of mechanical parts, electronic parts, medical instruments, and other various objects 2, the moving mechanism 3 is operated to move the objects 2 to be cleaned. The mounted cleaning table 1 is lowered and inserted into the cleaning tank 5, and liquid cleaning, steam cleaning, or both cleaning is performed.

After completion of this cleaning and steam cleaning, the moving mechanism 3
is operated in the upward direction of the washing table 1. Then, the object to be cleaned 2 placed on the cleaning table 1 is stored in the processing chamber 4 provided above the cleaning tank 5, and the cleaning tank 5 and the processing chamber 4 are shielded.

This shielding is performed by the shielding body 6 as the washing table 1 rises.
The engaging portion 8 protruding from the side surface is engaged with the engaging frame 16 protruding from the outer periphery of the communication port 10 on the cleaning tank 5 side.
The processing chamber 4 and the cleaning tank 5 are shielded by rotating and sealing the shielding body 6 using the support shaft 7 as a fulcrum.

After this shielding is performed, the processing mechanism 14 for removing the cleaning liquid 13 adhering to the object 2 to be cleaned is activated. This processing mechanism 14 is equipped with activated carbon that can adsorb a solvent.

The processing mechanism 14 is connected to the processing chamber 4 via a communication path 15 through which gas can flow. Therefore, the gas in the processing chamber 4 can be continuously processed by the processing mechanism 14 while introducing outside air until the solvent is completely removed.
As a result, organic solvents and the like adhering to the object 2 to be cleaned can be reliably removed.

After this treatment, if the object 2 to be cleaned is taken out from the treatment chamber 4, no harmful gases will be diffused into the chamber or inhaled by the operator, making it possible to carry out safe cleaning operations.

Further, the object 2 to be cleaned to which the cleaning liquid 13 has adhered is stored in the processing chamber 4 without exiting from the cleaning apparatus, and the cleaning liquid 13 adhered thereto is removed. Therefore, not only is there no need for transferring the object 2 to be cleaned to the processing mechanism 3 as in the conventional method, but there is also no need to diffuse the solvent.

Further, in the above embodiment, the processing chamber 4 is provided above the cleaning tank 5, but in other embodiments, the cleaning tank 5 and the processing chamber 4 may be provided in parallel, and the moving mechanism 3 is also connected to the washing table. It may be configured to move in a plane, and any design is possible depending on the purpose of cleaning.

Effects of the Invention Since the present invention is configured as described above, the cleaning liquid attached to the object to be cleaned after cleaning can be removed.
Remains in the cleaning device without any hassle.
Reliable removal processing is possible, and this removal processing can be performed with less diffusion of harmful substances such as organic solvents to the outside.

In addition, since the processing chamber communicates with the processing mechanism while being shielded from the cleaning tank by the shielding body, excess solvent vapor is not sent to the processing mechanism, and processing efficiency can be increased.

In addition, the communication port is opened and closed as the washing table moves up and down by rotating the plate-shaped shield using the support shaft as a fulcrum, so the mechanism is simple and inexpensive, and the communication port can be reliably shielded. can be done. Further, since the processing chamber and the shielding body are automatically shielded as the washing table is raised, the timing of the shielding is not disturbed.
