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 installs a chain conveyor in a sealed manner on the ceiling of a shower booth 21 which is closed (the outlet and inlet are open), and hangers 22 are moved from the chain conveyor at required intervals. The object 23 to be cleaned is suspended from the same hanger 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 to inject water or cleaning liquid onto the object 23 to be cleaned. 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 hanger passage 27 and adheres to the conveyor device. This, coupled 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 the service life of the equipment, and oil in the mechanical parts can leak along with water droplets to the hanger. 22 and the object to be cleaned 23
This caused paint to adhere to the paint, 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 of the 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.

Furthermore, the device shown in Japanese Utility Model Application Publication No. 51134074 also has a device for preventing corrosion of the conveyor device due to (sprayed) cleaning liquid. By flowing pressure fluid into the positive pressure chamber, the spray cleaning liquid is prevented from rising.

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.

The present invention can solve all of the above problems, that is, it can effectively prevent ice mist from leaking out of the shower booth despite its inexpensive structure, and maintenance such as repair and replacement of the conveyor device and shower booth is extremely easy. The purpose of the present invention is to provide a shower cleaning device that can perform the following tasks.

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) a conveyor device suspended in the shower booth, and (c) an ejection pipe for generating negative pressure, which is disposed in the shower booth at a location directly below the banger passage and whose ejection opening is directed downward. This relates to a shower cleaning device.

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.

Immediately below the banger passage 2 on the ceiling of the shower booth, a negative pressure generating blowout pipe 12 having holes at required intervals is installed. ) flows downward into the booth, thereby generating negative pressure directly below the banger passage 2 and preventing leakage of water mist.

The injection pipe 5.5 in the booth 1 is U-shaped and branches off from the water supply pipe 8.

In addition, 9 in the figure is an object to be cleaned, 10 is a cleaning liquid recovery tank, 1
1 is a pump that pumps 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 to be cleaned 9 is suspended from the banger 4 and moved at a required speed, and the required fluid (for example, air) is jetted downward from the negative pressure generating jet pipe 12 at the same time as the spraying operation. Then, a negative pressure is generated directly under the banger passage 2, which causes air to be sucked into the booth 1, so that the water mist inside the booth 1 is
Rather than flowing upward from the passage 2, air is sucked 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 rotation 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.
