Description

[Detailed Description of the Invention] The present invention relates to a shower cleaning device that is used as a pretreatment process for painting and the like.

As shown in Fig. 1, the conventional shower cleaning device has a chain conveyor installed in a sealed manner on the ceiling of a shower booth 21 (the exit and entrance are open), and the bangers 22 are moved from the chain conveyor at required intervals. The object to be cleaned 23 is suspended from the same banger 22, and the injection pipe 25 is branched in a U-shape to face each other from the water supply pipe 24 passed through the bottom, and water or cleaning liquid is injected onto the object to be cleaned 23. was.

A partition plate 26 is provided between the injection chamber A and the ceiling space B, but the water mist from the shower in the injection chamber A enters the ceiling space B through the banger passage 27 and adheres to the chain conveyor device. This, combined with the fact that the ceiling space B is sealed and moisture cannot escape, causes deterioration such as rust and corrosion in the mechanical parts of the equipment, shortening its lifespan, and the oil in the mechanical parts together with water droplets. It travels through the banger 22 and adheres to the object to be cleaned 23, causing paint defects.

In order to solve these problems, several improvements have been made in the past, including the device shown in Japanese Utility Model Publication No. 47-38747.

In this device, the shower booth is equipped with a conveyor device surrounded by a rotating speed at the top, and an intake window is provided on one side of the rotating speed, and a duct that communicates with an exhaust fan is installed on the other side. Water mist, etc. inside the tank is exhausted to the outside via a rotor and a duct.

However, in this configuration, since the conveyor is not open to the atmosphere, there is still a risk that some water mist may flow into the conveyor, so it cannot be said to be perfect.

In addition, the device requires an exhaust fan, duct, and rotating speed, making the structure complex and expensive to manufacture.

Furthermore, since the conveyor is surrounded by a rotating shaft, repair or replacement of the conveyor or the like requires removing the rotating shaft, which is complicated.

Furthermore, the presence of the rotating speed blocks light transmission inside the shower booth, making it dark inside and making work inside the booth complicated.

The device disclosed in Japanese Utility Model Application Publication No. 51-134074 also has a device for preventing corrosion of the conveyor device caused by the spray cleaning liquid, and this device is equipped with a positive pressure chamber containing the conveyor device above the shower booth. , the spray cleaning liquid is prevented from rising by flowing pressure fluid into the positive pressure chamber.

However, even in this configuration, since the conveyor is not open to the atmosphere, it is difficult to inspect and repair the conveyor.Furthermore, the shower booth is also difficult to inspect and repair because it cannot receive sunlight.

This invention can solve all of the above problems, that is, it can effectively prevent leakage of water mist etc. to the outside of the shower booth while having an inexpensive structure, and can perform maintenance such as repair and replacement of the conveyor device and shower booth. It is an object of the present invention to provide a shower cleaning device that can perform cleaning extremely easily.

The present invention consists of (a) a shower booth having a narrow banger passage extending longitudinally approximately in the middle of the ceiling, and (b) a shower booth installed above the shower booth in an open state to the atmosphere, and a banger passing through the banger passage. (c) air pipes installed symmetrically on both sides of the ceiling in the shower booth and blowing air along the back surface of the ceiling; (d) ceiling of the shower booth; The present invention relates to a shower cleaning device that includes an air guide that is symmetrically disposed directly below a banger passage and changes the air flow downward.

The present invention will be explained below based on the embodiments shown in the drawings.
FIG. 2 shows an outline of the structure. The shower booth 1 is of an open type with a banger passage 2 opened in the ceiling, and a conveyor device 3 such as a chain conveyor is supported above the banger passage 2.

Specifically, the conveyor device 3 is supported by guide rails 6 and supported by legs 7 on the ceiling of the booth 1.

As is clear from this, the chain conveyor 3 is open to the atmosphere, and the booth 1 can also receive sufficient light through the banger passage 2.

An air pipe 13 having jet ports at required intervals is provided above the side wall of the shower booth 1, and compressed air sent from an air pump flows through this pipe 13.

Then, shower booth 1 is placed opposite the spout.
Curved air guide 1 near banger passage 2 on the ceiling
2 is provided.

With this configuration, when air is blown out from the air pipe 13, negative pressure is generated directly below the banger passage 2, thereby preventing water mist from entering the conveyor device 3.

The injection pipes 5, 5 in the booth 1 are U-shaped and the water supply pipe 8
More branched.

In the figure, 9 is an object to be cleaned, 10 is a cleaning liquid recovery tank, and 11 is a pump that pumps the cleaning liquid to the water supply pipe 8.

In an actual painting line, several shower booths with this configuration are installed, and each booth goes through the steps of, for example, washing with water → degreasing → washing with water → washing with hot water → pickling → washing with water → washing with pure water. Painting in→
Processing is performed in a printing device.

In this invention, the object 9 to be cleaned is suspended from the banger 4 and sprayed while moving at a required speed, and at the same time as the work is being carried out, air is ejected from the air pipe 13 toward the bottom of the shower booth 1 via the air guide 12. Negative pressure is generated directly under the passage 2, which causes air to be sucked into the booth 1, so that the water mist in the booth 1 does not flow upward from the banger passage 2, but instead sucks air into the interior. .

As described above, the present invention has the following effects.

(1) By simply generating negative pressure directly below the banger passage in the shower booth, it is possible to effectively prevent water mist, gas, etc. inside the booth from escaping upward from the banger passage, causing rust and deterioration of the conveyor equipment. , consumption can be greatly reduced.

(2) Since the conveyor device can be made open to the atmosphere, (a) there is no need for rotational speed, etc. for the conveyor device, and manufacturing costs can be reduced.

(b) The conveyor device can be inspected and repaired easily.

(C) The inside of the shower booth can also receive sufficient light through the banger passage, making it easy to inspect and repair the inside of the shower booth.
