Description

The invention relates to equipment for applying paint coatings and is intended for dyeing products moved by a continuous and intermittent suspension conveyor and a pushing conveyor.

The aim of the invention is to improve the technical, economic and operational characteristics of the line and reduce the production area by reducing the size of the suspension cleaning unit.

FIG. Figure 1 shows schematically a production line for dyeing products; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows the node I in FIG. 2; in fig. 4 shows a section BB in FIG. one; in fig. 5 shows a section B-B in FIG. one; in fig. 6 - section G-Y in FIG. five; in fig. 7 is a section d-d in fig. four; in fig. 8 is a view E of FIG. 7; in fig. 9 is a view of FIG. 3

The production flow line consists of the coloring chamber 1, the drying chamber 2, the cooling chamber 3, the loading 4 and the unloading 5 devices, the cleaning unit 6 and the hanging conveyor 7 with detachable hangers 8, the removable part 9 of which has rollers 10 in the upper part located on the same axis on both sides of the suspension, and their horizontal bar 11 fixed below. After the unloading device 5, the pollution indicator 12 is installed on the conveyor 7, functionally connected by a removable device including the monorail 13, d 14 configured as a pneumatic cylinder mounted on the frame 15. The removable device installed Pa carriage 16 for moving the gripper with the removable portion 9 of suspension onto the inclined roller conveyor 17 and then to the cleaning unit 6. The latter consists of a perch section with a bath 18, a washing section 19 and a blower 20, in which inclined non-driven roller tables 21 and 22 and lifting and lowering sections 23 and 24 with limiters 25 and 26 are installed in the form of a spring-loaded stopper. The lifting and lowering sections 23 and 24 are connected to the drive drums 27 and 28. On the conveyor 7, after the cleaning unit 6, a sensor 29 is installed to signal that the suspension conveyor is not on the conveyor and is functionally connected to a lever-removable device installed at the outlet of the cleaning unit 6.

The contamination indicator 12 may be made electrical, magnetic, induction, or other, responsive to the thickness of the paint layer applied to the metal suspension. The indicator device (Figs. 5 and 6) is made in the form of parallel guides 30 and 31, one of which 30 is fixed, the second 31 is spring-loaded 32 and can move in the horizontal plane and interact with the limit switch 33.

To remove the lower part of the suspension 8, the carriage 16 has a lever 34 with a seat interacting with the roller 10 of the detachable part of the suspension extreme to it (Fig. 7 and Fig. 8). The suspensions are mounted on the lifting and lowering sections using stoppers 25 and 26, made in the form of a stopper (Fig. 9), consisting of a conventional spring-loaded 35 lever 35, turning from the actuator 37 (electric or pneumatic), beforehand specified program or signals from the limit switches (not shown) or by pressing the lifting and lowering sections 23 and 24.

The flow line for coloring products is as follows.

When approaching suspension 8 to the contamination indicator 12, the latter is triggered if the thickness of the suspension with a layer of paint deposited is greater than acceptable, while the movable guide 31 moves away and presses the limit switch 33, at the signal of which the monorail 13 rises, engages with rollers 10 the removable suspension part 9 rises together with the latter, and the suspension 8 on the carriage 16 rolls down and is placed by the horizontal bar 11 on the inclined roller conveyor 17. At the same time, the monorail 13 is lowered lower, releasing ku 8 which skatyvaets on roller conveyor 17 on lifting and standpipe section 23, pressure on the limit switch (not shown). The signal of the last section 23 with the suspension 8 under the action of its own weight is lowered into the bath 18 of the dipping section and when reaching the roller table 21, the stopper 25 of the lifting and lowering section 23 releases the suspension 8, which rolls onto the roller table 21, after which the lifting and lowering section 23 the drum 27 rises to its original position. Suspension 8 gradually moves along roller table 21 through bath 18 to stopper 26 and rolls to lift-lower section 24, which with the help of a driving drum 28 (at a switch signal) rises from bath 18 and moves the suspension to an inclined roller 22, and itself under its own weight goes down to its original position and, when reaching the lower position, takes the next suspension, which from the roller table 21 moves and is installed on the lifting-lowering section 24. At the same time, all the other suspensions 8 roll down along the roller table 21 to at the stage below.

On the third inclined roller table 22, the suspensions 8 are gradually lowered, the passage of the washing section 18 and the blowing section 20. Last (located at the lowest end

the roller table 22) the suspension 8 after the signal from the sensor 29 mounted on the conveyor 7, about the absence of the removable part 9 of the suspension 8 in the place of overload is picked up from the cleaning unit 6 by the carriage 16 of the monorail 13, which together with the suspension 8 rises and the carriage 16 rolls down . The cleaned suspension 8 is installed on the overhead conveyor 7 and moves to the loading device 4.
