Description

The invention relates to devices for dyeing articles and can be used for dyeing cylindrical shaped articles such as pipes and augers on an overhead conveyor.

The purpose of the invention is to improve the performance of the device.

FIG. 1 shows a device for automatic painting of articles; in fig. 2 is a section A-A in FIG. one.

The device for automatic painting of products includes an overhead conveyor 1, mounted on carriages 2 of conveyor 1 of suspension 3 with attachment points for products 4 and 5 and the mechanism of their vras, yeni, and paint sprayers 6.

The mount of the upper product 4 is made in the form of adjacent suspensions 3 mounted on the ends and axes 7 and 8 facing each other with asterisks 9 and 10. The mount of the lower product 5 is made in the form of additional axes 11 and 12 with asterisks 13 and 14 suspended on the sprockets 9 and 10 are connected by chains 15 and 16c to the outwardly facing pins 17. Axes 7 and 8 are rigidly connected to the ends of the product 4, and axes 11 and 12 are rigidly connected to the ends of the product 5.

The rotation mechanism of the products 4 and 5 is made in the form of inclined guides 18 and 19 along the conveyor 1, which interact with the pins 17. The guides 18 and 19 are located on both sides of the chains 15 and 16 and oppositely inclined.

The guides 18 and 19 are mounted on racks 20 and 21 movable in a plane perpendicular to the conveyor 1. The racks 20 and 21 are mounted on carriages 22 and 23 connected to the pneumatic actuator 24. On the conveyor 1, limit switches 25 and 26 are mounted, connected with operation of the pneumatic actuator 24 and spray guns 6.

The device for automatic dyeing works as follows.

Products 4 and 5 are fed into the zone of the spray gun 6 through conveyor 1.

At this time, the carriage 2 of the suspension 3 reaches the first limit switch 25, the signal of which activates the pneumatic actuator 24, which moves the pillars 20 and 21 on the carriages 22 and 23 and brings the inclined guides 18 and 19 closer to the branches of the chains 15 and 16. Moving along with the suspensions 3 chains 15 and 16 abut their pins 17 against the oppositely inclined guides 18 and 19. The movement of the pins 17 along the inclined guides 18 and 19 causes one of the branches of the chains 15 and 16 to rise and lower the other, which causes the sprockets 13 and 14, and with them s 4 and 5.

At the same time, the signal of the end switch 25 supplies the paint to the spray guns 6, which spray the paint onto the surfaces of the rotating and simultaneously moving along the conveyor products 4 and 5.

When the carriage 2 reaches the end switch 26, which corresponds to the complete painting of the product surface, a signal is received to stop the paint supply to the spray gun 6 and to the pneumatic actuator 24 to remove the guides 18 and 19 from engagement with the pins 17. The painting of the products ceases, the products stop rotating and conveyor 1 is removed from the painting zone. When a plow into the spray area of new products, the work cycle is repeated.

The proposed device allows the automatic coloring of two products simultaneously, which improves the coloring performance. When equipped with additional chain pendants with asterisks, the device allows simultaneous coloring of several products. The stationary placement of the spray guns improves the quality of the applied coating. The arrangement of the inclined guides on both sides of the chains prevents the products from swinging and also improves the quality of the applied coating.
