Description

[Detailed description of the invention] Industrial application field The present invention relates to a vertically moving type cleaning device in which a cleaning liquid phase, a steam cleaning phase, a cooling phase, etc. are provided in the vertical direction, and the leakage of solvent gas is surely prevented. That is.

Conventional technology Conventionally, a cleaning liquid, a steam generation section, etc. are located at the bottom of a cleaning tank, a steam cleaning section, a cooling section, etc. are sequentially formed at the top of this, and the object to be cleaned is moved vertically through this section. There were various types of cleaning methods. For example, in the system disclosed in Japanese Utility Model Application Publication No. 51-132866, a cage containing objects to be cleaned is rotated by a chain to improve contact between the objects to be cleaned and the cleaning liquid.

However, this method not only strongly agitates the cleaning liquid in the chain and scatters the cleaning liquid to the outside of the cleaning tank, but also exposes the chain and cage support plate that came into contact with the cleaning liquid during the cleaning of the object to be cleaned. do. Further, due to the presence of the chain, the cleaning tank cannot be sealed with a lid, so that harmful solvent gas is significantly diffused to the outside, making it impossible to put it to practical use.

In addition, in order to eliminate this drawback, as shown in FIG. 1, a cylinder 1 such as an air cylinder or an oil cylinder is located on the side of the cleaning tank 2, and a connecting plate 4 is connected at right angles to the piston rod 3 of the cylinder 1. There is a system in which a connecting pipe 5 is inserted into and out of the cleaning tank 2 via a connecting pipe 5, and a mounting table 7 for holding an object to be cleaned 6 is connected to one side of the lower end of the connecting pipe 5. This method allows the cleaning tank 2 to be sealed with the top plate 8 and does not use a chain.
Compared to the cleaning device described in Publication No. 132866, it has the advantage of significantly less diffusion of solvent gas. However, even in the method shown in FIG. 1, since the connecting pipe 5 enters and exits from the top plate 8, airtightness of the inlet/outlet portion 9 is incompletely maintained, and solvent gas flows out from the inlet/outlet portion 9. In addition, since the connecting pipe 5 that has come into contact with the solvent protrudes outside from the cleaning tank 2, the solvent is diffused into the atmosphere, increasing the amount of solvent used, which is not only uneconomical but also undesirable from the health management perspective of workers. It was hot.

Problems to be solved by the invention The inlet/outlet section is designed to solve the above-mentioned problems, and is designed to ensure efficient cleaning using a solvent while also ensuring prevention of diffusion of solvent gas. This is what I am trying to do.

Means for solving the problems In order to solve the problems mentioned above, the present invention
A cylinder is fixed vertically on the upper surface of the top plate of the cleaning tank, and a piston rod protrudes from the bottom end of the cylinder so that it can move forward and backward into the cleaning tank, and a mounting table for the object to be cleaned is connected to the side of one end of the piston rod. A rotating shaft is formed in the cleaning tank in the vertical direction by penetrating the mounting table so as to be able to move up and down, and this rotating shaft can be rotated by a motor that is sealed and located on the outer surface of the upper part of the cleaning tank. At the same time, a worm gear is attached to the rotating shaft so that it can slide vertically but cannot rotate, and this worm gear is connected by a chain to a rotating roller for rotating the round basket provided on the mounting table.
The rotational force of the worm gear is transmitted to the rotary roller through a chain, and the object to be cleaned is placed on a mounting table so that it can be moved up and down from the cleaning section to the inlet/outlet section.

Function Since the present invention is constructed as described above, the piston rod of the cylinder fixed to the upper surface of the cleaning tank body can be directly projected into the cleaning tank body so as to be freely advanced and retracted without using a connecting pipe or a connecting plate. can do. Therefore, the bottom end of the cylinder is
It can be securely fixed to the cleaning tank body and maintain airtightness, and there is no need to create a minute gap in the protruding part of the connecting pipe that slides out of the cleaning tank and cause solvent gas to leak out. Not at all. Further, since the piston rod that comes into contact with the solvent moves back and forth within the cylinder, the attached solvent does not come into contact with the outside air, and no diffusion of solvent gas occurs on this surface. Therefore, the solvent is not wasted, and favorable results can be obtained in terms of health management of the workers.

In addition, the rotational force of the rotating shaft that passes through the mounting table in a vertically movable manner is transmitted via the worm gear and chain provided on the rotating shaft to the rotating roller of the round cage provided on the mounting table. The round basket can be rotated and washed on the stand. In addition, the worm gear is attached to the rotating shaft so that it can slide vertically but cannot rotate, so it can move up and down as the mounting table moves up and down, and the round cage can be moved while moving the mounting table up and down. This enables complicated movements such as rotating the square basket, placing the square basket on a rotating roller and swinging it back and forth, and making good contact between the cleaning liquid and the object to be cleaned.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 20 is a cleaning tank, and a cylinder 22 such as an air cylinder or an oil cylinder is fixedly formed in the vertical direction on the upper surface of one side of the top plate 21. There is. This fixation is achieved by airtightly fixing a flange 23 provided at one end to the upper surface of the top plate 21, and a piston rod 24 protrudes into the cleaning tank 20. A supporting member 26 having rollers 25 projecting from both sides is connected and fixed to one end of the piston rod 24 in the projecting direction. This support member 26 is supported by a support frame 27 fixedly formed on one side of the cleaning tank 20 so as to be vertically movable but not swingable. Furthermore, a mounting table 30 for storing objects to be cleaned, such as a round basket or a square basket, is fixed to one side of the support member 26. This mounting table 30 supports the piston rod 24
a connecting member 31 having one end fixed to the connecting member 31;
It consists of a mounting table 34 on the upper surface, and this mounting table 34
A rotating roller 33 is provided at an interval between the round baskets 32 containing the objects to be cleaned.

Further, a connecting member 31 constituting the mounting table 30 is passed through the rotation shaft 35 so as to be vertically movable. The lower end of this rotating shaft 35 is supported via a bearing 37 at the lower end of the cleaning tank 20, and the upper end of the rotating shaft 35 is attached to a motor 36 sealed in the upper part of the cleaning tank 20 using a bearing 37.
Rotating force is obtained by connecting through the.
Further, a worm gear 39 is installed on the outer periphery of the rotating shaft 35 so as to be vertically movable but non-rotatable via a key groove 38 provided in the axial direction. This worm gear 39
is immovably fixed to the mounting table 30 by a fixed frame 41 provided on the connecting member 31. Further, a chain 43 driven by a worm 42 connected to a worm gear 39 is connected to the rotating roller 33, thereby enabling the rotating roller 33 to rotate.

In addition, a cleaning liquid phase 44 is provided at the bottom of the cleaning tank 20, and a cooling phase 45 is provided above the cleaning liquid phase 44.
There are 6. And these cleaning liquid phase 4
4. The cooling phase 45 and the inlet/outlet portion 45 are formed so that the mounting table 30 can move up and down arbitrarily to perform the cleaning work of the object to be cleaned.

In addition, an inner lid 47 is provided between the cleaning portion of the object to be cleaned, such as the cleaning liquid phase 44, steam cleaning phase, and cooling phase 45, and the inlet/outlet portion 46.
It is airtightly divided by This inner lid 47
is placed on the top surface of a protruding collar 49 that protrudes inwardly of the cleaning tank 20 so that it is pushed up and opened as the mounting table 30 rises by a bumping rod 48 that protrudes from the top surface of the mounting table 30. ing.

In addition, in the entrance/exit part 46, there is a round basket 3 for storing items to be cleaned.
2, or an entrance 52 for entering and exiting the square basket 51
is provided on one side, and this entrance/exit 52 follows the frame 53, by means of a shutter 54 that can slide upward.
It is closed so that it can be opened.

In the structure as described above, the round basket 32
Alternatively, in order to clean the object to be cleaned stored in the square basket 51, the cylinder 22 fixed to the upper surface of the top plate 21 of the cleaning tank 20 is actuated, and the piston rod 24 is actuated in the contraction direction. With this contraction of the piston rod 24, the support member 2 is attached to the piston rod 24.
The mounting table 30 connected via 6 moves to the storage section 46 or the vicinity of the storage section 46. Then, the shutter 54 is opened, and the round basket 32 or the square basket 51 for storing the items to be cleaned is taken in and out from the entrance 52. In one example, when the round basket 54 is inserted, the round basket 32 comes into contact with the rotating roller 33. In this state, shutter 5
4 is closed and the cylinder 22 is actuated to extend the piston rod 24, the stage 30 is lowered into the cleaning liquid phase 44.

This cylinder 22 is fixed to the upper surface of the top plate 21 without intervening a connecting pipe, a connecting plate, etc., and projects directly into the cleaning tank 20 so as to be freely advanced and retracted. Therefore, the lower end of the cylinder 22 can be reliably fixed to the upper surface of the top plate 21 of the cleaning tank 20, and airtightness can be maintained. Therefore, there is no gap in the protruding portion of the connecting pipe that slides and protrudes from the cleaning tank 20, unlike in the conventional case, and there is no possibility that the solvent gas will flow out from this gap. Also, since the piston rod 24 that comes into contact with the solvent moves back and forth within the cylinder 22,
The attached solvent is not brought into contact with the outside air, and no diffusion of solvent gas occurs on this surface either. Therefore, the solvent is not wasted, and favorable results can be obtained in terms of worker health management.

In addition, if the rotation shaft 35 that passes through the mounting table 30 so as to be vertically movable is rotated by the prime mover 36, the worm gear 3
9 and rotates the rotating roller 33 via the chain 43, the round basket 32 placed on the mounting table 30 and in contact with the rotating roller 33 is
Rotary cleaning can be performed on 0. Further, since the worm gear 39 is attached to the rotating shaft 35 so that it can slide in the vertical direction but not rotate, it can move up and down as the mounting table 30 moves up and down.
The round basket 32 can be rotated while moving up and down, and the objects to be cleaned inside can be made to make complex movements and have good contact with the cleaning liquid. Also corner basket 5
1 is placed on the rotating roller 33, by rotating the rotating roller 33 forward and backward, it is possible to perform complex movements such as swinging the square basket 51 back and forth, thereby preventing contact between the cleaning liquid and the object to be cleaned. It can be considered as good.

Effects of the invention Since the invention is constructed as described above,
The lower end of the cylinder is securely fixed to the top plate of the cleaning tank main body, making it possible to maintain airtightness. Therefore, as in the past, it is not possible to scatter the solvent with a chain,
There is no possibility that a minute gap will occur at the protrusion of the connecting pipe that slides and protrudes from the top plate of the cleaning tank main body, and that no solvent gas will flow out. Further, since the piston rod that comes into contact with the solvent moves back and forth within the cylinder, the attached solvent does not come into contact with the outside air, and no diffusion of solvent gas occurs on this surface either. Therefore, the solvent is not wasted, and favorable results can be obtained in terms of worker health management.

In addition, the rotational force of the rotating shaft that passes through the mounting table in a vertically movable manner is transmitted to the rotating roller of the round cage provided on the mounting table via a worm gear and chain that can move vertically relative to the rotating shaft. Because it is a holder, the round basket can be rotated and washed on the mounting table. It is also possible to rotate the round basket while moving the mounting table up and down, or to place the square basket on a rotating roller and swing it back and forth, ensuring extremely good contact between the cleaning liquid and the object to be cleaned. It is possible to do this.
