Abstract

PURPOSE:To reduce the process length and to improve treating efficiency by moving a body to be coated orthogonally to a guide rail and sizing the specified equipment among the coating equipment so as to move in the body. CONSTITUTION:A spray tank 11, a dipping tank 12, a dipping tank 13, a dipping tank 14 and a spray tank 15 are successively arranged along a coating line to constitute coating equipment. The guide rail 16 is laid above the equipment 11-15 along the coating line, a self-traveling hanger 20 is suspended, and an automobile body 10 is held by the hanger 20 and treated in the equipment 11-15. In this case, the body 10 is held so that its longitudinal axis is orthogonal to the guide rail 16. As for the tank 13 for degreasing, film forming, electrodeposition, etc., requiring a long treating time, the width in the left and right direction (longitudinal direction of guide rail 16) is made about three times larger than those of the tanks 12 and 14 so that the body is moved in the horizontal direction and oscillated. The process length is reduced, and the treating efficiency is improved in this way.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a coating processing apparatus applied to a coating line for automobile bodies, etc.

[Conventional technology]

FIG. 7 shows an example of a conventional coating processing apparatus.

In the figure, a conveying wire 1 is stretched along a coating line, and is moved to the left at appropriate times by a driving means (not shown).

The hanger 2 includes a hanging wire 2a whose upper end is connected to the conveying wire 1, and a holder 2b suspended by the wire 2a.

The holder 2b holds an automobile body 3, which is an object to be painted, and the body 3 is positioned with its longitudinal axis along the conveying wire 1.

When the body 3 is moved above the dipping tank 4A by driving the wire 1, a lifting means (not shown) provided on the hanger 2 is activated. With this, the hanging wire 2
A is drawn out and the body 3 is immersed in the tank 4A, where processing such as water washing is performed.

Next, the body 3 is raised and then moved to the spray booth 5A. Then, treatments such as spray washing and the like are performed in this spray booth.

Thereafter, predetermined processing is also performed in the immersion/Jil tank 4B and the spray booth 5B.

Note that the above-described transport method for the body 3 is called a single-tank tact method.

[Problem to be solved by the invention]

In the conventional painting processing apparatus, since the longitudinal axis (longitudinal axis) of the body 3 is along the conveying wire 1, the immersion /
The width of J11m4 and the spray booth 5 must be set large, which increases the process length.

For example, if the processing time in tank 4B is the longest,
Processing efficiency is low because bodies are not transported from other processes until the processing time has elapsed.

SUMMARY OF THE INVENTION In view of these conventional problems, it is an object of the present invention to provide a coating processing apparatus that can shorten the coating length and improve processing efficiency.

[Means to solve the problem]

The painting processing apparatus according to the present invention includes a guide rail arranged along a painting line, a load movably suspended from the guide rail, and a traveling power and a longitudinal axis of the object to be painted relative to the guide rail. a self-propelled hanger comprising a holding means for holding the object to be painted in a manner orthogonal to each other; and a means for raising, lowering and swinging the object to be painted via the holding means; a plurality of painting processing equipment arranged in a row and accommodating the objects to be painted that have been lowered by secondary hangers; is set to a size that allows internal movement of the object to be coated.

[Effect]

It runs on its own along a hanger or guide rail. The object to be painted is transported in such a manner that the longitudinal axis of the object to be painted is orthogonal to the guide rail. Moreover, the painted body can be swung. Further, in the coating processing equipment pile in which the object to be coated can be moved internally, the object to be coated is run in the liquid.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of a painting processing apparatus according to the present invention applied to a painting line for automobile bodies 10. As shown in FIG.

In this embodiment, the painting processing equipment includes a spray tank 11, a dip/JIW tank 112, a dip/J1 tank 13, a dip tank 14, and a spray tank I! 1-5 are sequentially arranged and installed along the painting line.

A guide rail 16 is arranged above each of the above-mentioned installations (IIL-1 to 15) along the painting line.
A self-propelled hanger 20 is suspended from the guide rail 16.

Hereinafter, the structure of this hanger 20 will be explained with reference to FIGS. 3 and 4, which are a front view and a side view of the hanger.

As shown in FIG. 3, the hanger 20 is separated from the moving vehicle 200 and the holder 201.

The mobile vehicle 200 has an upper frame 203 and a lower frame 204 that are connected to each other by two rods 202,
Arms 205 are protruded from the left and right sides of the upper surface of the upper frame 203, respectively.

Each arm 205 is provided with a resin wheel 206 on the upper side that contacts the upper surface of the guide rail 16, and the arm 205 on the - side
5 is attached with a motor 207 for driving wheels 206.

As shown in FIG. 4, a pair of winches 208 are attached to the lower surface of the upper frame 203.

The tips of the wires 209 hung on these winches 208 connect to pulleys 21.0.211 and 212.
are led out from the front center and rear center of the lower frame 204 to the lower surface side of the frame, respectively.

The holder 201 includes a support frame 213 and four rods 214 whose upper ends are attached to the four corners of the support frame 213, which are arranged side by side at intervals in the front-rear direction (direction perpendicular to the plane of the paper in FIG. 3). two rods 214
A pair of body mounting tables 215 are installed between the body mounting tables 215.

The upper end of each rod 214 is pivoted so as to be rotatable about an axis Jl+ parallel to the guide rail 16,
The table 215 also has the same axis J! They are pivoted so that they can move together around 2.

The hanger 20 configured in this way is connected to the travel motor 20.
By actuating 7, it is possible to move along the guide rail 16.

Further, by operating each winch 208 in the direction in which the wire 209 is paid out, the holder 201 can be lowered as shown in FIG. 5. At this time, by changing the wire payout amount of each winch, the body mounting table 215 is tilted as shown in the figure, and the body 10 is accordingly tilted.

Further, in the state shown in FIG. 3 in which the holder 201 is raised to the uppermost position, the pin 216 provided at the top of the rod 214 is connected to the cylindrical body 216 provided on the lower surface of the lower frame 204.
17, thereby attaching the holder 2 to the moving vehicle 200.
01 is fixed.

Note that the cable 218 shown in FIGS. 4 and 5 is
It is provided to ground the body 10.

The body 1o with the handle 20 held therein is moved to above the spray tank 11 shown in FIG. be descended. In this tank 11, for example, spray washing is performed.

After spray washing, the body 10 is lifted up to the top of the spray tank 11 and then moved to the top of the immersion tank 12.
It is immersed in the processing liquid in this Vj12 in the manner shown in FIG.

That is, the body 10 is in the tank 1 with the rear slope lowered.
2, and then body 1- in this Ify12.
0 is oscillated. Thereafter, the body]0 is raised with the rear side being raised and returned to the horizontal position.

Incidentally, in this immersion tank 12, processing such as water washing is performed.

The next step, immersion tfJ13, has a width in the left-right direction (longitudinal direction of the guide rail 16) equal to that of the other immersion t! 12.
It has a continuous tank structure set to about three times that of No. 14.

The body 1-O that has been transported above the immersion tank 13 is lowered into the tank 13 and then moved laterally.

In addition, in this tank 13 as well, the body 13 is arranged and swung in the manner shown in FIG. And this tank 1
In No. 3, the above-mentioned rocking continues while the body is laterally moved.

In this tank 13, a longer processing time than other tanks can be ensured by the above-mentioned lateral movement effort. Therefore, in this embodiment, processes such as degreasing, film formation, and electrodeposition, which require long processing times, are performed in this tank 13.

As described above, when the body 10 is moved laterally in the tank 13, the processing efficiency particularly on the side surfaces of the body 10 is improved due to the agitation rP of the processing waves accompanying this movement.

Next, processing such as washing with water is performed in the immersion tank 14 and the spray fff 15, respectively, and then the body 10 is carried out for the next process.

In addition, the spray tank 11.15 simultaneously sprays the treatment l& onto the front, rear, left, right, and downward sides of the body 10.
■A nozzle is provided so that it can be used.

Body 10 in each of the above immersion baths 12, 13 and 14
The rocking of the body 10 is performed in order to remove air pockets formed on the surface of the body 10 and eliminate untreated areas.
In this example, the body 1o is oscillated at a oscillation angle of 100 to 17''. This oscillation is as shown in FIG. This is done by alternately driving each winch 208 in different directions, and this swinging significantly improves processing efficiency.

On the other hand, when the body 10 enters and exits the six tanks 12 to 14, the rear side of the body 10 is lowered in order to easily and rationally enter and exit the tanks.

That is, since there are many openings on the rear side, by lowering this rear side and entering the tank, the processing liquid can enter the body 10 more quickly, thereby allowing smooth entry into the tank. Furthermore, by lowering the rear side and unloading the tank, the processing liquid can be quickly removed from inside the body 10, thereby smoothly unloading the tank while minimizing the amount of processing liquid taken out. I can do it.

Note that when entering the tank, the body 10 is lowered at high speed until it lands on the liquid, and lowered at low speed until it reaches a crowd of people.

The gear is then lowered at a medium speed until reaching all stages, and the above-described rocking is performed at the lower end.

In addition, in the said Example, when the body 10 is taken out from each tf111-15, the body is rocked. In this way, since the treatment liquid is quickly dripped from the body 10, a uniform coating film can be formed on the body 10 when the treatment liquid is a paint. In addition, as described above, the amount of processing liquid carried out can be significantly reduced.

FIG. 6 illustrates a series of painting processing steps executed in an actual painting line.

In the figure, S indicates spray treatment and D indicates dipping treatment. In addition, ``dial'' indicates that the immersion tank has a single tank structure (see 111.1 and 12.14 in Figure 1), and ``ren'' indicates that the tank has a continuous tank structure (see tank 13 in Figure 1). It shows.

The present invention can be effectively applied not only to automobile bodies but also as a coating treatment apparatus for a coating line for coating other objects to be coated.

〔Effect of the invention〕

According to the present invention, since the object to be painted is transported in such a manner that the longitudinal axis of the object to be painted is perpendicular to the guide rail, the length of the painting process can be shortened.

In addition, we are equipped with painting processing equipment whose width in the direction along the painting line is set to a size that allows the object to be painted to swing internally, so this equipment is suitable for processing processes that require long processing times. By using this, the processing efficiency of the entire painting line can be improved.

In other words, when processing for a long time using a processing equipment with a single tank structure, waiting time will occur in other processes, but the present invention, which has a self-propelled handle and the above-mentioned wide painting processing equipment, According to the above, since objects to be coated can be independently stacked and transported in the processing equipment, the above-mentioned waiting time can be eliminated and processing efficiency can be improved.

Furthermore, since the hanger is provided with a swinging means, processing efficiency and coating quality can be improved by swinging the main body to be coated in the processing equipment.
