Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a vertically moving type cleaning device that uses an organic solvent as a cleaning liquid and allows a cleaning table on which an object to be cleaned is placed to move up and down. The purpose is to reliably prevent leakage of solvent gas to the outside.

Conventional technology Conventionally, a cleaning liquid, a steam generating 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, and the object to be cleaned is moved vertically through this section. There have been various types of cleaning equipment, but as shown in Figure 2, a cylinder 1 such as an air cylinder or an oil cylinder is used in a cleaning tank 2.
A connecting pipe 5 is inserted into and out of the cleaning tank 2 through a connecting plate 4 that is connected at right angles to the piston rod 3 of the cylinder 1. Placement table 7 for cleaning items 6
is connected. In this method, since the connecting pipe 5 enters and exits from the top plate 8 of the cleaning tank 2, the airtightness of this inlet/outlet part 9 is incomplete, and as the solvent gas flows out from the inlet/outlet part 9, the connecting pipe 5 that has come into contact with the solvent ,
Since it protrudes from the cleaning tank 2 to the outside through the inlet/outlet part 9, the solvent is diffused into the atmosphere, increasing the amount of solvent used, which is not only uneconomical but also undesirable from the health care perspective of workers.

Problems to be Solved by the Invention The present invention attempts to solve the above-mentioned problems, and uses an organic solvent as a cleaning liquid.
Vertical movement type cleaning equipment, in which the cleaning table on which the object to be cleaned is placed can be moved up and down, reliably prevents leakage of solvent gas to the outside, reduces the amount of solvent used, and is economical. The aim is to make it more convenient and desirable from the health management perspective of workers.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention places a sprocket wheel for rotating the chain connected to an electric motor on the top surface of the cleaning tank, and isolates this sprocket wheel from the outside air. At the same time, the chain is connected and fixed to a mounting table for the object to be cleaned inserted into the cleaning tank, and the rotating shaft is fixed in the cleaning tank by penetrating the mounting table vertically freely. The rotational force of this rotational shaft is transmitted to the rotary roller for the round basket provided on the mounting table via a rotational force transmission mechanism, and the object to be cleaned can be moved up and down from the washing section to the entrance/exit section. It is.

Function As described above, the present invention covers the sprocket wheel for rotating the chain connected to the electric motor, which is fixed to the upper surface of the cleaning tank main body, with a covering body so as to isolate it from the outside air, so that the chain can be cleaned. Even if it is inserted into the tank, there will be no leakage of solvent gas due to the creation of a minute gap in the protrusion of the connecting pipe that slides out of the cleaning tank, and the chain that comes into contact with the solvent will not Since the chain rotates endlessly within the cleaning tank and the covering body, the solvent adhering to the chain 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 basket provided on the mounting table via the rotational force transmission mechanism. It also enables complex movements such as rotating the round basket while moving the mounting table up and down, or placing the square basket on a rotating roller and swinging it back and forth, allowing cleaning liquid and This allows for good contact with the cleaning object.

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 sprocket wheel 24 for rotating a chain 23 connected to an electric motor 22 is located on the upper surface of one side of a top plate 21. This sprocket wheel 24 is covered with a covering 25 to isolate it from the outside air, and the chain 23 is inserted into the cleaning tank 20. At one end of the chain 23 in the insertion direction into the cleaning tank 20, there are rollers on both sides. A support member 27 with a protruding portion 26 is connected and fixed, and this support member 27 is supported on a support frame 28 fixedly formed on one side of the cleaning tank 20 so as to be movable up and down and not swing. A mounting table 30 for a round basket 32 or a square basket containing objects to be cleaned is fixed to one side of the container. This mounting table 30 includes a connecting member 31 whose one end is fixed to the chain 23 via a support member 27, and a rotating roller 33 provided at a mounting interval of a round basket 32 containing an object to be cleaned. It consists of a mounting section 34 on the upper surface. Also, the mounting table 30
A connecting member 31 constituting the cleaning tank 2 passes through the rotating shaft 35 so as to be movable up and down.
0 via a bearing 37, and the rotating shaft 35
The electric motor 3 whose upper end is sealed in the upper part of the cleaning tank 20
6 through a bearing 37 to obtain rotational force, and a worm gear 39 is installed which can freely move up and down but cannot rotate through a key groove 38 provided in the axial direction. A drive chain 43 is immovably fixed to the mounting table 30 by a fixed frame 41 provided on the member 31, and is driven by a connected worm 42.
It is connected to the rotating roller 33 and allows the rotating roller 33 to rotate.

With the above configuration, the mounting table 30 can move up and down the cleaning liquid phase 44, the cooling phase 45, the entrance/exit part 46 of the object to be cleaned, etc. in the cleaning tank 20, and the cleaning operation of the object to be cleaned can be performed. is formed. In addition, the cleaning part for the object to be cleaned, such as the cleaning liquid phase 44 and the cooling phase 45, and the inlet/outlet part 46 are airtightly partitioned by an inner lid 47. It is placed on a protruding collar 49 that protrudes inward of the cleaning tank 20 so as to be opened by a stopper 48 as the mounting table 30 rises. Further, the entrance/exit part 46 is provided with an entrance/exit 52 on one side for entering and exiting the round basket 32 or square basket 51 for storing items to be cleaned, and this entrance/exit 52 is provided with a shutter that can be slid upward following the frame 53. 54, it is releasably closed.

Effects of the Invention As described above, the present invention covers the sprocket wheel for rotating the chain, which is fixed to the upper surface of the cleaning tank main body and is connected to the electric motor, with a covering body so as to isolate it from the outside air. Even when inserted into the cleaning tank, one end of the chain can be securely fixed to the septic tank body and maintain airtightness, and there is no small gap in the protruding part of the connecting pipe that slides and protrudes from the cleaning tank body. There is no leakage of solvent gas, and since the chain that comes into contact with the solvent moves back and forth between the coating and the cleaning tank, the attached solvent does not come into contact with the outside air. Also, it does not cause diffusion of solvent gas. 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 to the rotating roller of the round basket provided on the mounting table via the rotational force transmission mechanism. It is 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. It is possible to make very good contact with the Furthermore, since the mounting body is moved up and down by a chain, the piston rod is not projected upward like a cylinder, and there is no need to increase the size of the device or place restrictions on the installation location.
