(54) DEVICE FOR PAINTING PRODUCT-PIE

one

This invention relates to process equipment for spray painting products.

A device for painting articles is known, which contains a conveyor with carriages for moving articles, a device for rotating articles, a spray gun disposed with possibility of movement on guides arranged in a plane parallel to the plane of movement of conveyor 1.

However, this device does not provide uniform quality coverage.

Closest to the invention, a device comprising a conveyor with carriages for moving products, a device for rotating products around an axis, a spray booth and a spray gun positioned for movement on a frame mounted on the frame, which are located in a plane parallel to the plane of movement of the conveyor and installed with inclination to the axis of rotation of product 2.

In such a device, the product is painted when the atomizer moves in one direction, for coloring the next product, the atomizer must return to its original position, which reduces the performance of the device.

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

This is achieved by the fact that in the proposed device for painting products comprising a conveyor with carriages for moving products, a device for rotating products around an axis, a spray booth, a spray gun positioned for movement on a frame mounted on a frame, which are located in a plane parallel to the plane of movement the conveyor, and installed with, 5 inclination to the axis of rotation of the product, the frame with the guides mounted on the axis and kinematically connected with the drive mechanism for rotating the frame with the guide around this axis by an angle equal to at least dvu.m angles of inclination of the guide 20 to the axis of rotation products.

FIG. 1 shows the proposed device, a general view; in fig. 2 is a view along arrow A in FIG. 1, the position of the slant guides during the forward stroke of the spray gun; in fig. 3 - the same, the position of the inclined guides during the return stroke of the spray; in fig. 4 is a diagram of the operation of the device and the position of the sprayer during the forward and reverse course. The device for painting products comprises a conveyor 1, equipped with carriages 2, containing rotating mandrels for products, ending with asterisks 3, cooperating with the device 4 for rotating the products. To move the sprayer 5 along the guides 6 from the drive device 7, a lead screw 8 is provided, which moves the support 9 with the sprayer. The guides 6 are fixed on the frame 10, which, with the help of a support, is mounted on the axis 11 fixedly mounted on the device case. The frame 10 through the lever 12 is connected with the rod of the power cylinder 13, which provides the swing of the frame 10 with the guides 6 on the axis 11. Sensors 14 and 15 serve to disable the drive of the displacement of the sprayer, as well as to simultaneously turn on the power cylinder 13 through the electromagnetic valve providing the swing of the frame 10 on the axis 11. To enable the drive of the movement of the sprayer and turn on the sprayer, there is a sensor for the interaction of the stop mounted on each carriage 2 of the conveyor (not shown in the drawings). The device is equipped with a spray chamber 16. The device operates as follows. The product 17 to be painted is installed in the rotating mandrel of the carriage 2 of the conveyor 1. The step 5 is in its extreme position (see Fig. 2). When the product is moving, the sprocket 3 engages with the device 4 for rotation and the product begins to rotate around the axis, simultaneously moving on the conveyor. The carriage stop through the sensor activates the spray gun 5 and the drive device 7 for moving the spray gun. The product is colored. In the meantime, the atomizer moves from position B (see Fig. 4) to position C, and the product is moved by the conveyor from position T to position T;. . Having reached the extreme position, the caliper 9 acts on the sensor 14, which sends a signal to shut off the operation of the spray gun 5 and the drive device 7 for its movement. The same sensor generates a signal for switching to the operation of the ram 13, which rotates the frame 10 with the guides and the lever .2 with guides by an angle equal to the two tilt angles of the guides, and the guides occupy the position shown in FIG. 3. Now the sprayer 5 takes the initial position for coloring the next product (see Fig. 4, position B 0 and moves to position Bj (see Fig. 4 end of coloring), and the product moves to pinch t from position T to position G, (see Fig. 4). Thus, the products are continuously colored when the sprayer is moved to one and the other side, i.e., the idle is eliminated. After the end of the painting, the product 17 is moved to the existing compartment for the substrate. maschiny by eliminating idle strokes. Apparatus for dyeing products comprising a conveyor with carriages for moving products, a device for rotating products around an axis, a spray booth and a spray gun positioned for movement on mounted on a frame guides arranged in a plane parallel to the plane of movement of the conveyor and installed with an inclination to the axis of rotation of the product, characterized in that, in order to increase the productivity of the device, the frame with guides is mounted on the axis and the frame aticheski associated with a drive mechanism for turning the frame with the guide around the axis by an angle equal to at least two angles -naklona guide to the rotation axis of the article.
