Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cleaning device for cleaning oil, fat, and foreign matter adhering to various parts.

[Conventional technology and its issues]

When manufacturing precision mechanical parts and electrical equipment parts, the manufactured parts are subjected to a cleaning process because oils and fats used in the manufacturing process and foreign matter from the process adhere to the manufactured parts.

Various types of cleaning equipment are commercially available for use in this cleaning process, but 8-move cleaning (in a cleaning solvent) is particularly suitable for cleaning parts that are crowded with facets generated during the manufacturing process. Ultrasonic cleaning is suitable for adhering minute foreign matter and oil. Further, after the cleaning, foreign matter floating in the cleaning solvent will adhere to the surface of the cleaning parts, so it is preferable to perform shower cleaning and steam cleaning with a clean solvent.

For this reason, conventionally, there is a cleaning device disclosed in JP-A-1-143674, which is explained with reference to FIGS. 1 and 3. Room E, steam cleaning room, drying room C,
The holding chambers B are arranged in sequence above, and the buckets 15 containing manufactured parts to be washed are sequentially moved to the chambers E, D, C, and B by an arm that moves up and down, and immersed. In the cleaning room E, solids such as facets and oil are removed by ultrasonic vibration and swinging of the bucket 15, and in the steam cleaning room, deposits from solvents are removed by shower cleaning and steam cleaning, and then dried. In the chamber C, the vaporized solvent is condensed to dryness due to the cooling effect, and in the holding chamber B, it is kept until the vaporized solvent content is reduced to the permissible content.

However, in this device, since the items to be washed do not move smoothly within the bucket 15, the shower, steam, etc. do not reach the entire area of the items to be washed evenly, resulting in uneven cleaning.

An object of the present invention is to eliminate the above-mentioned uneven cleaning.

[Means to solve the problem]

In order to solve the above problems, in the present invention, in the above-mentioned cleaning device, the bucket 7) is rotatably provided on the arm, and a means for rotating the bucket is provided on the upper part of the arm via a transmission mechanism. It was established.

The receiver I installed at the bottom! 12 and returned to the wooden lid 24. Since not only the cleaning solvent but also water vapor is condensed in the condensed liquid, the water and solvent are separated in the moisture separator 24 and used for reflux.

Reference numeral 25 denotes a cleaning solvent tank, which is connected to the cleaning solvent boiling tank 10 via a pump 26 by a pipe (not shown), and the pump motor M is stopped in response to a detection signal from a float switch to control the level of the tank 10.

27 is an exhaust system, the intake pipe 28 of which is connected to the upper part of the exhaust chamber A, and the exhaust pipe 33 is connected to the lower part. Intake pipe 28
A throttle valve 30 is interposed, and a horn 29 is provided at the tip of the throttle valve 30. On the other hand, the exhaust pipe 33 is similarly provided with a throttle valve 31, and opens to the outdoors from the wall W via a blower 34 and an activated carbon bite tank 35.

Inside the exhaust chamber A, as shown in Fig. 8(a) and (b),
A filter 40 is provided to partition the inside of the filter.
This filter 40 is located above (outside) the communication port 41 with the indwelling chamber B, and has an upper compartment that prevents the vaporized solvent from the indwelling side B from directly entering the upper compartment. A collection pipe 42 is provided, and an intake pipe 28 is connected to this collection pipe 42, and pipes 43 are branched over the entire area of the compartment, and air is supplied to the entire area from a plurality of small holes in each pipe 43. gushes out.

Next, the operation of the embodiment will be explained according to standard operating procedures. It is assumed that all other preparations such as sequence setting for operation have been completed.

First, open the door 37 of the exhaust chamber A by removing the hook 40'.
Same crime 3 for putting bucket 15 containing laundry items into exhaust chamber A
7 and hang the hook 40'.

At this time, a backing is attached to the bracket where the door 37 and the exhaust chamber A are in contact to maintain airtightness.

Next, the air cylinder 39 is activated, the shutter 3 is opened, and the space between the exhaust chamber A and the detention chamber B is opened. Insert your hand into the airtight glove 2, push the bucket 15 into the detention chamber B, and install it on the bearings 21a and 21b.

When the bucket 15 is installed, the ram of the air cylinder 16 is lowered, and the bucket 15 is also lowered and immersed into the immersion cleaning chamber E. At this point, the ultrasonic vibration oscillator 14 is activated, and air supply and exhaust to the air cylinder 16 are repeated, and the vibration continues for a set period of time for cleaning.

Next, the bucket 15 is raised by the operation of the air cylinder 16 and stopped at the steam cleaning chamber. At this point, the coagulated and recovered clean cleaning solvent is ejected from the shower cleaning nozzle 7 for a set time to perform shower cleaning.

When the shower cleaning is completed, the bucket 15 continues to remain in that position and is further cleaned with vaporized solvent from the solvent boiling tank 10.

When the set time for the steam cleaning ends, the air cylinder 16 is activated and the bucket 15 is held and dried in the cooling drying chamber B for the set time. In this drying, the vaporized solvent is constantly cooled and condensed by the coiled cooling water pipe 4, and the
The solvent condensed in 2 is collected and led to a water separator 24.

In each process of cleaning, steam cleaning, shower cleaning, and drying in the cleaning chamber E, the motor 18a drives the bucket 15.
The machine rotates and the items to be washed inside it flow. As a result, the entire area of the object to be washed is evenly washed and dried.

Once dry, the air cylinder 16 further moves upward to lift the bucket 15 to the detention chamber B, and after a short time the shutter 3 opens. After this, the air cylinder 16 is inserted into the airtight glove 2 and the bucket 15 is moved to the exhaust chamber A. Then, the shutter 3 is closed and the blower 34 is activated.

As a result of this operation, air is taken in through the intake pipe 28, dust is removed by the filter 40, and the air is ejected from the small holes of the container pipe 43 to evenly reach the entire exhaust chamber A. As a result, the vaporized solvent in the exhaust chamber A is replaced with intake air and is smoothly exhausted.

In this way, the vaporized solvent in the exhaust chamber A is removed, the vaporized solvent is adsorbed by the activated carbon adsorption tank 35 via the exhaust pipe 33, and the purified air is discharged outdoors.

The blower 34 is stopped after being driven for an arbitrary set time, and the door 37 of the exhaust chamber A is opened to take out the bucket 15.

Thereafter, cleaning is performed in the same manner.

In the embodiment, a gear mechanism is used as the means for transmitting power from the motor 18a to the bucket 15, but it goes without saying that known means such as a chain belt may be used.

Further, as a rotation support means for the bucket 15, as shown in FIG. 9, a roller 21d is rotatably attached to the auxiliary arm 21, and the bucket 15 is rotatably supported by the roller 21d via its rib 15c. , by rotating the gear 15b of the roller 21d, the bucket 15 may be rotated by the roller 21d. At this time, the roller 2 on the same axis
1d.

21d is preferably connected by a cylindrical body 21e as shown by the chain line.Furthermore, in each embodiment, the gear 15b may be provided directly on the shaft 20b without using the pinion 20c.In this case, in FIG. has a cylindrical shape that fits into the auxiliary arm 21.

〔Effect of the invention〕

In the present invention, since the bucket is configured to rotate as described above, cleaning efficiency can be improved.
