(54) INSTALLATION FOR PAINTING PRODUCTS

one

The invention relates to the coloring of articles, in particular to sputtering devices. neither polymeric powder paints, and can be widely used in the automotive, instrument-making, electrical and other industries.

A coater is known to contain its sprayer associated with a chain drive placed on a bed 1.y

However, such a device is unreliable in operation, difficult to maintain, takes up a lot of production space, the parts are painted on one side only.

The closest in technical essence and the achieved result is a device for painting products, including a tunnel-type painting chamber with vertical guides mounted on both its sides, on which carriages with sprays connected to the mechanism of their return spacing are mounted. -accessible movement 2.

The disadvantage of this setup is that it can be painted only

sheet products. The mechanism for the reciprocating movement of the nozzles takes up a lot of production area and is difficult to operate.

The purpose of the invention is to increase the reliability of work and reduce size.

This is achieved by the fact that a device for painting products, including a tunnel-type painting chamber with vertical guides mounted on both its sides, on which carriages with sprayers associated with their reciprocating movement are mounted, is provided with a camera mounted on the ceiling board. -shaped frame, and the mechanism of reciprocating movement is made in the form mounted on the frame by means of an axis with the possibility of swinging around it from the drive of the rocker arm with the same arms along the length, on which cables connected with carriages are fixed.

Claims (2)

To enable adjustment of the stroke of the carriage, the drive of the rocker arm swing is made in the form of a variator mounted on the U-shaped frame with a disk with holes fixed on its shaft, and the rocker arm is connected to it by means of a tongue bearing a finger on one of the disc holes. FIG. I shows the installation, general view; in section; in fig. 2 is a view A of FIG. 1. The installation contains a tunnel-type painting chamber 1 with vertical guides mounted on both its sides 2. On the ceiling panel 3 of the chamber I, an U-shaped frame is fixed 4. On the guides 2 there are mounted carriages 5 with nozzles 6. Each carriage is made cross-shaped, on the opposite-horizontal ends of which are rigidly strengthened by means of blocking over 7; spherical supports 8 for holding the nozzles 6. At the vertical ends of the carriage there are reinforced rollers 9 and spring clamps 10. The carriages 5 are connected to their back rest mechanism movement made in the form mounted on the U-shaped frame 4 through the axis 11 with the possibility of swing around it from the drive of the rocker arm 12 with the same length arms, on which are fixed the cables 13 connected with the carriages 5. The drive of the rocker arm is made in the form of on the frame 4 of the variator 14, with a hole disk 15 fixed on its shaft, and the rocker arm is connected to it by means of a connecting rod 16 carrying a finger 17 at the end of it, which enters one of the holes of the disk 15. The installation also contains a load carrying conveyor 18 sec. 19 for parts 20, pipelines 21 for supplying the powder mixture and fluidization container 22. The installation works as follows. Parts 20 (for example, a RAF minibus), assembled, on suspensions 19 on a load carrying conveyor 18, enter the sputtering chamber 1. The powder paint, which is located in the fluidization tank 22, is transformed into a state of magnification and, with the help of the ejectors in the tank, is fed into the pipes 21 and sprayed through the spray guns 6. The charge powder paint is carried out inside the spray gun by means of a charging device, to which a high voltage (30-50 kV) is supplied through a high-voltage cable from a high voltage source. When the variator 14 is turned on, a disk 15 mounted on the variator shaft is rotatably driven. Through the rod 16, connected with the yoke 12, the carriage 5 is reciprocally moved, moving along the guides 2 and connected with the rocker through the cables 13. The change of the stroke length of the carriage 5 is accomplished by shifting the finger 17 of the head 16 to the corresponding holes on the disk 5, located along the radius. The stability of the position of the carriage relative to the guide is achieved by adjusting the clamp 10 and the rollers 9 fixed on the carriages and located on both sides of the guide. By releasing or tightening the flare nut 8 on the spherical supports 7, the distance from the part to the sprayer and the angle of its inclination can be adjusted. The frame 2 of the sprayer movement mechanism also serves as a connecting link for the sputtering chamber 1, the ceiling shield 3 of which is cut to its full length for passing the suspensions. This allows the conveyor 18 to be taken out of the spraying chamber and to prevent it from being sprayed with powder paint and at the same time to reduce the dimensions of the chambers by half, to ensure the required rigidity of the structure, to reduce the metal consumption by three times. The proposed design of the installation allows ensuring high reliability of operation of all the installation nodes in the course of long-term operation. The installation and its components are easily accessible for maintenance, adjustment and repair. Claims 1. An apparatus for painting products, comprising a tunnel-type painting chamber with vertical guides mounted on both sides, on which carriages with sprayers are mounted, associated with a reciprocating movement mechanism, characterized in that increase the reliability of work and reduce the size, the installation is equipped with a U-shaped frame fixed to the ceiling panel, and the reciprocating mechanism is designed as mounted on the frame using B hingeably around the drive rocker identical with the length shoulders, on which are fixed the cables associated with carriages. 2. Installation according to claim 1, characterized in that, in order to enable adjustment of the carriage stroke, the swing arm of the rocker arm is designed as an variator mounted on a U-shaped frame with a disk with holes fixed on its shaft, and the rocker arm is connected to it by means of a connecting rod that carries a finger on its end, which fits into one of the holes in the disk.
