Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a degreasing cleaning device, specifically a cleaning solvent tank,
This bath cleaning equipment involves sequentially inserting objects to be cleaned into a cleaning steam tank, a drying tank, etc., and degreasing them using an organic solvent.The purpose of this equipment is to improve the operating efficiency of the cleaning process. The objective is to improve the efficiency of the cleaning process and to automate the 0C cleaning process.

Mineral oils that adhere to machined parts are generally trichlor ethylene, trichlor ethane, etc.

Since it dissolves well in organic solvents and the nuclear solvent can be easily dried by slight heating, cleaning using the above-mentioned solvents has been widely carried out in the past, and there are many types of cleaning equipment.

A conventional cleaning device of this type is, for example, as shown in FIG. In the figure, (1) is a hot liquid tank filled with a solvent (2) (e.g. trichlor ethylene, trichlor ethane, etc.) heated below the boiling temperature of the organic solvent (2);
8) is a cooling tank filled with solvent (2) cooled to about room temperature;
(4) is a steam tank filled with vapor (2a) of solvent (2), (
5) is a drying tank installed at a high place where the vapor (2a) of the solvent (2) is diluted;
)(5) is housed in the chamber (6). A pipe (7) is installed in the upper part of the chamber (6), and the solvent (2) circulates inside the pipe (7) and is cooled to about room temperature and sent to the cooling tank (8).
It is poured inside. The solvent (2) poured into the cooling tank (8)
) fills the cooling tank (8), and the solvent (2) overflowing from the cooling tank (8) flows into the hot liquid tank (1), and then the next VC@liquid tank (1).
) into the steam tank (4). Inside each tank (1), (8), (4), (6) are metal slatted boards (mounting members) (8m), (8b), (8C).
) and (8d) are fixed, and a large number of items to be cleaned α1 (for example, small metal press parts, metal shafts, etc.) are stored on the cough drainboard board. There is. The cleaning device α0 first cleans the object α in a hot liquid bath (1).
After soaking in the cooling tank (8), then soaking in the steam tank (Yu no Wish), and drying in the drying tank (6), cleaning is completed.In addition, the hot liquid tank ( 1) A heater is installed at the bottom of the steam tank to heat or boil each solvent (2).

Incidentally, in the cleaning apparatus α0 having the above configuration, the process of sequentially moving the object to be cleaned αp among the various types (1), (8), (4), and (5) often relies on manual labor. However, before i device 00
Organic solvents (2) which have a negative effect on the human body are used, which is not good for the human body, and there is a tendency to prohibit the use of trichlor ethylene in particular due to the danger of liver damage, carcinogenesis, etc. Furthermore, installing a large exhaust duct in order to improve the work environment (1) causes the problem that (2) a large amount of steam (2a) is discharged and the solvent (2) is extremely consumed, making it uneconomical. Ta.

Therefore, in order to automate the movement of the object to be cleaned 0, an automatic cleaning apparatus using a transport head aO as shown in FIG. 2 was devised. Conveying head (10 is various (1), (8), (
4), it is slidably attached to the support shaft (1e) installed above (5), and a lifting rod α is inserted into the center of the head (io) so that it can move up and down. The stored objects (to) are suspended from the lower end of the lifting rod Q71, and the various types (1), <a), (4
), (5) and the lifting rod Q? ), it is lowered into various tanks (1), (8), (shun, and (5)), and after a predetermined time, it rises together with the lifting rod 0 and moves above the next tank.This operation is repeated to clean the tank. Complete the entire process.

However, the device with this configuration is
The heights of b), (8C), and (8d) are the same as those of the above-mentioned various types (1), (
8), (4), and (5), it was difficult to provide a plurality of conveying heads αθ and control the vertical distance of each vertical lift bar α by varying it. Therefore, it is necessary to attempt automation using a single transfer head, but cleaning work for the next object to be cleaned cannot be started until all cleaning processes are completed, and processing work is delayed. The drawback was that it was inefficient.

The present invention eliminates the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to the drawings. FIG. 3 shows a simplified overall side view of the cleaning device, in which the same parts as in the prior art are given the same reference numerals and their explanations will be omitted.

The cleaning device (1) of this embodiment includes a hot liquid tank (1) and a cooling tank (
8), a steam tank (4), and a drying tank @.Furthermore, a mounting tank (22m) and a removal tank (22b) for attaching and removing objects to be cleaned α◇ are installed. A transport head (2) is movably installed above each type, and this transport head g3 is used for each type (1), (8), (4), @,
(22m) and (22b) are sealed together in a chamber to reduce the exhaust volume of solvent (2) vapor (2m) as much as possible. ) The object to be cleaned can be inserted or taken out from the door (not shown) at the bottom. Also, unlike the conventional method, the drying tank @ is placed at approximately the same low location as the other various types, and has a hot liquid tank (1), a cooling tank (8), and a steam N (
4), Drying tank (c) grating board (mounting member) (8a)
, (8b), (8C), (8d) and the installation is in the tank (22
a), the bottom (22a m) of the removal tank (22b)1. (
22b*) are all set to be at the regular height. In addition, steam (2a) is located near the opening of the steam tank (4).
A water cooling pipe (cooling member) (c) for condensing the water is provided, so that the steam (2a) does not leak from the steam tank (4), that is, the drying tank G! is adjacent to the steam tank (4).
■ is the same as the conventional one installed in a high place, and the steam (2
a) is made to be sparse.

The spindle a0 that holds the transport head is attached with a number of transport heads (C) forming a closed loop, only one of which is shown in the figure, and when the transport head (C) stops transporting, the Above each tank, there is always a transport head) that corresponds to and stops. Further, the transport head @ has a built-in simple lifting mechanism (for example, an air cylinder with fixed bottom dead center and top dead center) for raising and lowering the lifting rod @.

The rod (toward) can automatically attach and detach αe when the object to be cleaned α is stored at the lower end.
D (basket α8) with slatted boards (8a), (8b), (8C
), (8d) or the bottom (22aυ, (22b+)), and can be lifted up again, and each transfer head (2) moves the object to be cleaned α (22aυ, (22b+)) every time it is intermittently transferred to the drainboard board (22aυ, (22b+)). 8a), (8b), (8C), (8d) Place or lift the items to be cleaned into the next tank all at once. The lifting distance l is slatted board (8a) (sb) (8c) (8d
) and the bottom parts (22a, ) (22bs) are the same height, so it goes without saying that they are all set constant.

That is, various (1), (8), (4), (c), (22a
) with the object to be cleaned αυ stored in (to), and the object to be cleaned ap that has been cleaned in the take-out tank (22b).
By taking the items out of the chamber (to), the transfer head (A) automatically sends the items to be cleaned αυ to the next tank, so each type always contains the items to be cleaned αυ. This improves cleaning efficiency.

In the above embodiment, the heel (to) is automatically attached and removed by raising and lowering the elevator rod (to), but the heel (to) is attached to the tip of the elevator rod (to). It is also possible to insert or take out only the object to be cleaned αp in Q8, or to attach or remove the basket αe from the lifting rod (to) in the tank (2)) (22a) and removal tank (part) (22b). It may be made detachable. Furthermore, it is also possible to arrange each type in a circular manner so as to form a closed loop, and it goes without saying that all such modifications within the scope of the spirit of the present invention fall within the scope of the present claims.

As described above, the solvent cleaning device according to the present invention locates the drying tank at a low location approximately at the same height as each of the other cleaning tanks,
By installing slatted boards at the same height on which the items to be cleaned are placed in each tank, and by installing a cooling pipe at the opening of the steam tank filled with solvent vapor, the items to be cleaned can be placed on the same height. The device for loading and unloading and moving the tank is simplified, making it easier to automate the entire device, improving cleaning efficiency, and eliminating the need to expose the human body to harmful solvents. The value is enormous.
