Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a surface treatment chamber for surface treatment before painting or cleaning treatment after painting.

(Prior Art) Before painting, surface treatments such as degreasing, chemical conversion treatment, and cleaning are usually performed. In addition, after painting, cleaning treatments such as water washing are performed. aggregate, panels, etc.
In the case of long objects, a processing chamber is used in which a transport means for suspending and transporting the object and a riser installed along the transport line is installed. Surface treatment is performed by spraying solvents, chemicals, etc. from a riser as the material passes through.

(Problem that the invention aims to solve) However, in conventional processing chambers, the object to be processed shakes due to vibrations caused by the movement of the object to be processed or due to the pressure of the shower, and this hits the nozzle of the riser. In some cases, the injection port was damaged. When repairing a damaged injection nozzle, remove large objects,
Alternatively, in the case of a processing chamber for processing long objects, it is particularly troublesome and dangerous. Therefore, an object of the present invention is to provide a surface treatment chamber that can perform surface treatment on a long object without damaging the injection port of the riser due to the swinging of the object.

(Means for Solving the Problems) In order to achieve the above object, the surface treatment chamber of the present invention includes a transport means for suspending and moving the object to be treated, and a means for processing the object to be treated. In a surface treatment chamber in which a spray means for spraying a liquid is installed, a wire for protecting the spray means is provided between the above spray means and the object to be treated, and a wire for positioning the wire is provided on the inner wall of the surface treatment chamber. It is characterized by having a rod or tube.

As the conveying means, for example, a rail formed on the ceiling, a hook movable on the rail, and a motor for moving the hook can be used, and the object to be processed can be hung on the hook and moved. can.

As the spraying means, for example, a riser formed by forming an injection port in a pipe for supplying processing chemicals into the processing chamber can be used.

The protective wire is formed, for example, by stretching a plurality of wires spaced apart vertically in the direction of the conveyance line, but it is also possible to weave wires of the same thickness or thinner than the wires in the vertical direction. Or put a net-like material on it, or
Alternatively, it may be hung. Further, by further providing thin wires between the horizontal wires, stiffness can be given to the net.

A positioning rod or tube (hereinafter referred to as a support rod) is provided on the inner wall along a horizontal wire. Preferably, the support rod has a double structure consisting of two tubes. In this case, one end of the outer tube is fixed to the inner wall, and a locking part for holding the wire in a certain range of positions is provided at the tip of the inner tube. By moving this inner tube, the position of the locking portion can be adjusted so that it is at least on the inside of the riser. The locking portion preferably has a shape without corners so as not to damage the product to be processed, and is formed, for example, by horizontally attaching round rods to the upper and lower portions of the tip of the tube.

In the surface treatment chamber of the present invention, the object to be treated is suspended and moved through a protective wire in the treatment chamber, during which time the object is surface treated with chemicals etc. sprayed by a riser. The sprayed solvents, chemicals, etc. are received in a tank installed at the bottom of the processing chamber, and after being filtered, they are collected from the outlet installed at the outlet of the processed product and pumped into the piping of the riser above. recycled and reused. Further, when the surface treatment to be performed is degreasing treatment or preliminary degreasing treatment, it is necessary to heat the treatment chemicals in order to reuse them, so it is preferable to provide a heater in the tank.

(Function) The surface treatment chamber of the present invention is covered with protective wires, so the object to be treated is contained between the wires, and even if it shakes, it is suppressed by the protective wire and directly reaches the riser's injection port. There is no physical contact. Further, since the protective wire is held between the upper and lower locking parts of the support rod, it does not hit the injection port of the riser.

(Example) Hereinafter, the present invention will be explained in more detail with reference to Examples.

FIG. 1 shows a processing chamber 1 according to an embodiment of the present invention.
The processing chamber 1 includes a rail 9 for transporting a workpiece 4, a riser 2 provided along the rail, a protection wire 3, and a support rod 5. A hook 10 is attached to the rail 9, and the workpiece 4 is hung on the hook 10 and transported within the processing chamber, during which surface treatment is performed.

The riser 2 has pipes 11 installed at the upper part of the inner wall on both sides of the processing chamber 1 along the conveyance line.
A plurality of downward pipes are provided at intervals in the direction of the conveyance line in 1, and the pipes are arranged at intervals vertically,
Nozzle port 12 shaped as shown in FIGS. 6 and 7
The configuration includes the following. As a result, in the processing chamber 1 of this embodiment, surface treatment is performed by spraying a solvent or chemical for surface treatment from the injection port 12 of the riser while the object 4 to be treated is being transported. The sprayed chemicals are received in a tank 6 formed at the bottom of the surface treatment chamber 1 and passed through a filter 18.
After being heated by the heater 8 if desired, it flows to the outlet, is collected from the outlet 7 formed at the outlet, is pumped up into the upper pipe 11, and is reused.

The wire 3 is stretched inside the riser tube 2 in the processing chamber 1 in parallel to the conveyance line. FIG. 4 is a horizontal cross-sectional view of the entrance portion of the processing chamber 1 of this embodiment, and as shown in this figure, the wire 3 is suspended and supported by a support 19 at the entrance portion. Further, the wire 3 is supported by a plurality of support rods 5, 5, . The support rod 5 has a double structure consisting of a tube 5a whose one end is fixed to the inner wall of the processing chamber and a tube 5b inserted into the tube 5a. Round bars 13, 13 are stretched across the upper and lower ends of the tubes 5b arranged along the wire 3, forming a locking portion for the wire. Round bar 1
As shown in FIG. 3, a rectangular plate 14 is passed between the wires 3 and 13, and the wire 3 is held between the round bars 13 and 13 on this plate 14. tube 5a
and the tube 5b has a plurality of holes 15a, 15a, respectively.
. . . and a plurality of holes 15b, 15b, . By inserting the tube 5b
to be fixed.

Further, as shown in FIG. 4, a guide 17 is formed at the inlet portion, and the guide 17 includes a pipe 5a similar to the above, one end of which is fixed to the inner wall of the processing chamber.
Insert a tube 5c with a guide plate as shown in FIG. It is formed by selecting and matching the pins so that they are appropriate and inserting the pins 16. This corrects the large vibrations caused by the attachment of the object to be processed at the inlet.
The material to be processed can be easily introduced into the processing chamber.

(Effects of the invention) When surface treatment is performed using the surface treatment chamber of the present invention, a protective wire is stretched between the object to be treated and the riser, so even if the object to be treated shakes during the treatment, the riser can be protected. The injection port will not be damaged by hitting the injection port. Therefore, the dangerous and time-consuming repair work of the riser becomes unnecessary, the processing efficiency of the processing chamber increases, and the cost for replenishing damaged products can be reduced, which is also economically preferable.
