Description

one

The invention relates to devices for painting bulk products with approximately equal cross-sectional sizes and lengths, it is intended for use in painting the exterior surfaces of various products during their transportation on an overhead conveyor, such as barrels, drums, cylinders, and spherical surfaces and products parts of spheres.

A device for coloring volumetric products is known, comprising stationary guideway and a movable carriage made in the form of sectors, with spray guns mounted on it, connected through a kinematic connection by a force cylinder lj.

This device does not provide a uniform carriage movement and, therefore, a uniform coating thickness.

It is also known a device for dyeing volumetric products containing a carriage. with nozzles installed with the possibility of movement in the guide, and the power cylinder |: The last device is the closest to the described essence and achievable effect.

The disadvantages of this device are the need to use a large number of sprayers in connection with a small angle of oscillation of the carriage and the impossibility of painting the end surfaces of the products.

The purpose of the invention is to increase the angle of coverage of the product with the minimum number of nozzles and ensure the possibility of painting the end surfaces.

To achieve this goal, the nozzles are mounted on brackets with slats mounted on

5, a carriage which is connected to the rod of the power cylinder and is equipped with a gear that interacts with the rails of the brackets and is fixed on the guide rail with the additional rail.

0 The guide is installed with the possibility of rotation in a plane, perpendicular to: the plane of movement of the carriage. The drawing shows a diagram of the proposed device.

Claims (2)

The device for painting bulk items contains sprayers 1, mounted on brackets 2 with rails 3 mounted on carriage 4. QaQ. the rotor is mounted with the possibility of 3 movements in the guide 5, on which the additional rail 6 is fixed, the carriage is connected to the rod 7 of the left cylinder 8 and is equipped with gear 9, cooperating with the rails of the 2 5J brackets with the additional rail 6. The crank 4 can be rotated in the plane perpendicular to the plane of movement of the carriage 4 with the aid of the actuator 11. An overhead conveyor 12 is provided for transporting the products. A sensor 13 is provided for turning on the power cylinder 8. Device operation As follows When entering the painted product 14 into the painting area, a command from the control system 13 causes the power cylinder 8 to work, moving the carriage 4 relative to the directional 5 and the brackets 2 relative to the carriage. At the same time or after the required delay time (depending on the type of the product being painted, its shape and size ratio), the drive AND turning the guide 5 is turned on. Thus, the paint is produced by oscillating movement of the arms with sprays to the turn of the guide during transportation if the product is stationary in the painting zone, the ratio of the magnitude of the movement of the carriage and the brackets relative to the carriage will be proportional to the ratio of the number of teeth of the crown gears with the racks and the guide bracket. The angle of rotation and the speed of rotation of the guide are set in accordance with the dimensions of the product and the speed of its transport. The proposed device allows the use of a dp of painting products with a minimum number of sprayers, as well as painting the end facetances of products. Claim 1. Device for painting bulk products containing a carriage c. nozzles mounted for movement in a guide and a power cylinder, characterized in that, in order to increase the angle of coverage of the product with the minimum number of nozzles, the latter are mounted on brackets with slats mounted on a carriage that is connected to the stem of the pressure cylinder and provided a gear that interacts with the bracket rails and with an additional rail mounted on the guide rail, 2. The device according to claim 1, about tl and which is so that, in order to allow the coloring of the end surfaces, the guide is installed with the possibility of rotation in a plane, perpendicular to the plane of movement of the carriage.
