JPS5926167A - Apparatus for immersing hollow body such as fuel tank in liquid - Google Patents

Abstract

PURPOSE:To uniformly and efficiently coat the interior of a hollow body, by rotatably supporting a jig member for holding the hollow body around a point near the bottom of the hollow body acting as a fulcrum with a supporting member. CONSTITUTION:A shaft 22 rotatably pivoted with the frame of a treating basket jig is attached to both of the side surfaces 21 of an inner basket jig 2 with inclination to one of upper and lower sides and deviated from the centroid of a tank to the bottom side. Hence, a hollow body supported with the frame of the jig is directed downwards during being existent outside a liquid, but directed upwards during being existent in the liquid. At the same time, it acts as a float member for holding the rotating position of the frame of the jig with respect to the supporting frame because of its buoyancy. Consequently, the injection and discharging of the liquid into and from the hollow body are performed automatically, and coating or the like is facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid immersion device for hollow objects such as fuel tanks used in painting processes and the like.

To paint the inner surface of a hollow container such as a tank, fix the container and insert the paint gun from 1 into the injection tank.
You can spray the paint on the inside while rotating it, or you can apply paint inside and then rotate the container.
J: A method is adopted in which the coating is shaken and the remaining coating is removed at the end. However, these methods
Both methods are cumbersome to operate and are not suitable for automatically processing multiple containers.

On the other hand, the method of treating the inner surface of a hollow container by immersing it in a solution such as coating or cleaning agent is efficient because it allows a large number of containers to be handled at the same time, but on the other hand, it may cause air pockets and There are problems such as insufficient removal, which may result in defective products with uncoated areas or uneven coating.

Japanese Patent Application Publication No. 56-97570, Utility Model Application No. 111-1982! M7
In order to solve this kind of problem, each publication states that the object to be coated is immersed in the liquid with the liquid discharge part facing down, the air inside is inserted from the outside, and an air-bleeding vibrator is used. In this type of device, the injection port is placed on the top of the fuel tank, and when the injection port is small and deep, the tip of the pipe is completely removed from the container by connecting the I to the V. Not only is it impossible to hold the container at the bottom, but if the bottom of the container is uneven, it may be impossible to remove all the air from the uneven surface. Problems still remain.

In view of such problems, the present invention provides treatment methods such as coating or cleaning.
J1! Regardless of the shape of the hollow object to be treated,
A structure f? that can process these internal parts uniformly and efficiently. The purpose of this system is to provide an i'i LTh equipment, and its rat characteristic is to unload cargo into the d1 bath 71 and place a suspended hollow object into the liquid. The jig frame is attached to the support to be immersed using an eccentric support shaft.
It is supported horizontally in a rotational manner so that the hollow object held in this jig frame faces downward when it is outside the liquid, and faces upward when it is in the liquid. The support is provided with a floating member that maintains the rotating posture of the jig frame in the liquid by buoyancy.

Therefore, the details of the present invention will be explained below based on illustrated embodiments.

The drawing shows an example 7Ali of the present invention,
The number in the figure - 1 indicates a trolley-type processing basket jig that is suspended vertically relative to the paint tank 4 while moving along the travel path, and on both sides of this is an inner basket jig that will be described later. The upper and lower two frames supporting J-11.41 are fixed.
In the center of this width direction, there are two wooden guide rods 12 that guide the float 3, which will be described later, up and down. In this embodiment, the object to be coated is constructed as a one-piece frame for accommodating the fuel tank 5 as shown in FIG. υ1, the shaft 22 which is rotatably supported by the above-mentioned flenograph 11 of the processing basket jig 1 is shown in FIG. This shaft 22 is biased.
The installation is at position M.

Q, 1, is determined by the storage direction of the tank 5, and 11 at the point where the center of gravity of the tank 4 is on the side of the paper 52! / can be attached. Therefore, it is assumed that the tank 5 is housed at 17 in the l station of the shown inner jig 2 so that the injection [] 51 is at the bottom)'1!

The harmful body 24 (FIG. 2 (b)) that covers the eye 11 represents a spring piece for fixing the position V?i of the tank 5, respectively.

On the other hand, the top plate 31 is attached to the wooden guide rods 12, 12 of the saw 2, which are vertically fixed to the ``center in the 1j direction'' of the basket jig 1.
A bottomless box-shaped flow 1-3 is taken up and down by a sliding mechanism through a hole 52.32 provided in the float 3. Posture holding piece 33 of two upper and lower trees extending 11E horizontally toward the inside of the basket jig 1

51 - When these several fuel tanks 5 are housed, the inner basket jig 2 is supported on the processing basket jig 1 by ii+t+ 22, which is eccentrically located near the 18th part 52 of the tank 5. As shown in FIG. 1 and FIG. 6 (a), the tank 5 (r): assumes a suspended posture with the population 51 facing downward.

Next, when the processing basket jig 1 is lowered into the paint tank 5 in this state, there is a large amount of water in the paint, and the tack 5 has a large inlet port 51. Since buoyancy acts, the inner cage jig 2 is reversed around the axis 22 due to the buoyancy of the tank 5, as shown in FIGS. 2 and 6 (b).
Inject tank 5 (make 51 soil and paint its inside 1)

On the other hand, after 1 g of the reversal operation of the center turbo jig 2, the float 5 sank into the center and floated up due to the air trapped inside it, and the posture holding piece 53 integrated with it was reversed. It is pressed against the bottom of the inner basket jig 2 to prevent it from falling over.

Finally, when the tank 5 is filled with @bayashi and the float 6 is raised, 113 floats 6 from the liquid.
lowered and the inner basket jig 2 became free due to the breakage.
The weight of the upper part of the tank 5 causes it to turn over again 2, and as shown in FIGS. 1 and 6 (c), the inlet 51 is directed downward and the paint that has flowed into the tank is discharged. Through the following series of operations, the paint adheres to the inner surface of the tank 5, and the coating is completed.

The operation of the device of the present invention will be explained by taking the painting process as an example, and will explain how the inside of the tank 5 is cleaned, degreased, and chemically formed. IT, it is not necessary to say, ``Even in the culms, the present invention is used.''

As described above, according to the present invention, the jig part A" (for making a hollow-shaped object) is set at a point near the bottom of the hollow-shaped object as a fulcrum (711 Since it was supported in a bath liquid, the posture of a medium-sized object in CC can be changed to 7 people in the bath liquid by simply lowering the object to 1. ] can be -J'- so that 1.・shi'/]-person 1] is facing downward, and the content i-shape Q<>+ is inside. By using a simple IIS system, the liquid can be input and discharged in a self-H(1) manner and f
iH can be performed efficiently. Moreover, since the posture of the hollow-shaped proboscis is changed each time the person discharges the liquid, the liquid such as paint can be applied to every corner of the hollow-shaped object, regardless of its shape. It is possible to spread the paint evenly, and remove the unprocessed parts due to the unevenness of painting.)
Dividing Z by 4Jr equals 7iJ. In order to support the threatening force of jig abduction in the bath liquid, the ant force retaining layer that utilizes buoyancy is used to prevent the liquid from flowing inside the hollow object in the latter half of the culm.
