Description

The invention relates to devices for automatic coating of products and can be used in installations and automated dyeing lines for products of complex configuration.

The purpose of the invention is the expansion of technological capabilities during the coating application on products of complex configuration.

FIG. 1 shows a coating apparatus for articles; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 shows a section B-B in FIG. 3; in fig. 5 is a section of YYD in FIG. four; in fig. b - section dd in fig. four.

The device comprises a stand 1 with a carriage 3 mounted in its guides 2 and a mechanism for the vertical reciprocating movement of the carriage 3 including a variable speed motor 4 and a chain link mechanism 5.

On the carriage 3, by means of the arm 6 and the guide rollers 7, the telescopic arm 8 and its axial movement mechanism, including the motor-variator 9 and gear-rack drive gear 10, are mounted in the horizontal plane. The paint head 11 and the gears 12 are mounted on the arm 8. and 13, respectively, of its axial and angular rotation relative to the axis of the bar 8.

The axial rotation mechanism 12 by the coloring head 11 is made in the form of a brace 14 with two flanges 15 and 16 and axles 17 and 18 located in them. Between the flanges 17 and 18 there is a rotating pipe 19 with a partition 20 dividing it into two cavities. At the end of the pipe 19, ratchet crowns 21 and 22 are installed. In the partition 20, there are two additional pins 23 and 24 located coaxially with the pipe 19. In the cavities of the pipe 19, pneumatic cylinders 25 and 26 are mounted, rotatably mounted on the pins 17 and 23 , 18 and 24.

On the outer surface of the pneumatic cylinders 25 and 26, levers 27 and 28 are installed with stops 29 and 30 and with spring-loaded flat springs 31 and 32 with articulated swivel dogs 33 and 34.

In the pneumatic cylinders 25 and 26 placed movable spring-loaded stops 35 and 36 and spring-loaded latches 37 and 38.

Dogs 33 and 34 are installed with the possibility of engagement with the ratchet crowns 21 and 22, and movable stops 35 and 36 are installed with the possibility of interaction of the wedge-shaped working surfaces with stops 29 and 30, with the flow rods of the pneumatic cylinders 25 and 26 and the inner surface of the pipe 19.

Clamps 37 and 38 are placed with the possibility of interaction with movable stops 35 and 36 and flanges 15 and 16, which have wells on the surface. Mechanism

12 axial rotation is set coaxially to the rod 8.

The mechanism 13 of the angular rotation of the painting head 11 is made similar to the mechanism 12 and mounted on its rotary tube 19 perpendicular to the axis of the rod 8. The spray head 11 is installed in the grips 39 on the rotary tube of the mechanism 13. The pneumatic cylinders of mechanisms 12 and 13 communicate through trunnions and a pneumatic valve (not shown ) with compressed air system.

The device works as follows.

The manipulation of the painting head 11 in space is carried out upon the receipt of control signals from the tracking system for the dimensions and configuration of the product being painted. When the motor-variator 4 is turned on, the rotational movement of the shaft is transformed by the chain-link mechanism 5 into a vertical reciprocating movement of the carriage 3 with the rod 8 and the painting head 11 along the guide 2 of the rack 1.

The paint head 11 is brought closer to the painted surface of the product by axial movement of the rod 8 from the variator motor 9 by means of a rack and pinion gear 10.

Manipulation when coating a product with a spherical surface is provided by mechanisms 12 and 13, respectively, of the axial and angular turns of the painting head 11 in a given direction.

In the initial position, the painting head 11 is installed coaxially with the axis of the rod 8. Under the action of the springs, the stops 35 and 36 are pressed against the inner surface of the rotary tubes of the mechanisms 12 and 13 of the axial and angular twist of the painting head 11, which ensures the fixation of the position of the painting head. When compressed air enters through the trunnion 17 into the pneumatic cylinder 25, its rod moves to the right and acts on the wedge-shaped working surface of the movable stop 35. In this case, the movable stop 35 moves in the direction of the stop 29 of the lever 27, moves away from the pipe 19 and presses on the rod of the clamp 37, which enters into the hole of the flange 15 and fixes the position of the pneumatic cylinder 25 relative to the flange 15.

When moving, the stop 35 compresses the spring 39 and acts on the stop 29 27, causing it to turn. When the stop 29 is rotated, the dog 33 is rotated, which pushes one of the ratchets 21 of the pipe 19 and rotates the pipe 19 relative to the axis of the rod 8, and with it the painting head 11.

When the pneumatic cylinder 25 reaches the extreme right1, the position of the compressed air pressure in the pneumatic cylinder increases and the pneumatic valve is activated, which blocks the air supply and informs the cavity of the pneumatic cylinder with the atmosphere. With

the absence of pressure from the side of the rod of the pneumatic cylinder 25, the movable stop 35 under the action of the spring is pressed against the inner surface of the pipe 19 and fixes its position relative to the pneumatic cylinder 25. The rod of the clamp 37 is shifted to the right by the action of the spring and exits the hole of the flange 15. The stop 29 rotates in the action of the spring 31 initial position and moves the pawl 33 to align it with the depression of the next ratchet crown 21 of the pipe 19. When re-supplying compressed air to the pneumatic cylinder 25, the painting head is further rotated dexterous 11 with respect to the axis of the rod 8. To make the rotation of the spray head relative to the axis of the rod in the opposite direction, the compressed air is supplied through the axle 18 into the pneumatic cylinder 26,

the rod which acts on the movable stop 36 and the dog 34, which leads to the rotation of the pipe 19 and the painting head 11 in the opposite direction.

The mechanism 13 of the angular rotation of the painting head 11 operates similarly to the mechanism 12 and provides rotation of the painting head 11 relative to the axis of the rod 8 by an angle of ± 90 °. The mechanisms 12 and 13 allow the painting head to rotate in a given direction relative to the axis of the rod 8 and stop, if necessary, in intermediate positions, the number of which is determined by the number of ratchets.

The proposed device allows to automate the process of painting products with

complex configuration and allows remote control of the coating process.
