Description

I

The invention relates to the field of coating deposition by the method of dipping, in particular, to devices for applying coatings to hollow articles, namely, the body of the rollers of belt conveyors.

A known installation for applying overcoatings, comprising a housing, a bath for a treatment solution, a mechanism for transporting products to working positions 1, made in the form of a rotor with radially arranged mandrels, at the ends of which heads are fixed, a lodgment for supporting the product and a loading mechanism and unloading rotor.

However, such an installation does not provide a complete and high-quality coating of all surfaces, for example, with a rust converter, since this solution dries quickly and is difficult to remove. In addition, the solution flows unevenly from the products, the working bodies are not affected by the solution getting on them.

In order to increase the productivity and quality of the applied coating, we suggest that the installation of the bath is made in

There are two chambers located in guides of the hull with the possibility of independent lifting and lowering, and the cradle has a groove on the supporting surface and is located between the chambers.

FIG. 1 shows a general view of the installation in the initial position; in fig. 2 the same in the working position.

The installation consists of body 1, having

window 2 for loading and unloading products 3. In the case there is a bath made of chambers 4 and 5, mounted with the possibility of raising and lowering, nor from the actuators 6 in the guides 7 of the arctus. Chamber 4 is designed to pretreat the product in a degreasing solution, and chamber 5 is for protecting it with a rust converter. Above the chambers on the horizontal axis 8, a mechanism for transporting the products to the working positions is mounted, made in the form of a rotor 9, a periodic turning mechanism of the division mechanism (shown in the drawing). On the rotor, radially and evenly: the circles are fixed with mandrels} 10, which accommodate products. Angle H; e; “. Do the neighboring fprs ravegg de DEy to the angle of rotation of the rotor. At the end of each mandrel, an i-head 11 is reinforced, made in the form of an ictba; designed to keep the slide from sliding from the mandrel. In order to reduce the area of contact of the product with the mandrel on the cindral of the noi3ej; -x - the latter is provided on the crown 12. Under the rotors of the chamber -. The station 13 is fixed with a supporting surface for moving from the camera to the camera, and a slot J.4 for the passage of the heads 11. Window 2 has a loading / unloading mechanism that includes an IS rod with supports 1G and 17, moving back and forth through the window to the rotor axis from a drive, e.g. a pneumatic cylinder (not shown). In the process of processing 3 on the dash transport, the loading position is received, from which, when the golkat 15 moved to the right (see Fig. 1), the abutment 1 (: 5 is pushed onto the mandrel 10 of the rotor 9 before hanging on it. The rotor 9 rotates on the lunr,; The green box moves to the next position. When rotated, the ICD slides along the armor up to its stop with its end surface. The end face of the head 11 (see ({2). The camera 4 rises from the actuator 6 to the position where 3 is completely immersed in the degreasing solution. Simultaneously, the pusher 15 fur the loading-unloading bottom returns to its original position. After a period of time corresponding to the exposure of the product in the solution, the chamber 4 is lowered to the lower position. The solution is allowed to run off the solution, and then the rotor rotates another step. the surface of the cradle 13 and slides along it, and the head 11 of the mandrel passes into the groove 14. At the end of the rotation, a free mandrel is fed to the loading position and loaded with a blowing piece. The rotor rotates another step and the second product is treated with a degreasing solution similarly to the first. When the rotor is rotated by one step, the first product is set to the position of its processing by the transducer in the chamber 5 solution, which is moved by the driver 7 from the actuator 6 in the same way as chamber 4. The chamber 5 is lowered, allowing the pump to drain the excess solution, and rotates: another step. The first product enters the sugyki position with a stream of warm air and at the same time the next product is loaded onto the next free mandrel. Thus, the product is loaded onto the rotor bores for each double twist. When the first product arrives at the unloading position, all the rotor mandrels are loaded with products. In the unloading position, the pusher 15 with its stop 17 captures the product, and moving to its initial position, carries it through the window 2. The freed mandrel, when rotated, then rotates to the position of the front end and accepts the next product. The product is loaded simultaneously with the processing of others in the chambers 4 and 5 solutions. Thus, the proposed installation allows the products to be continuously processed successively in various solutions by dipping, both;: At the same time, the most complete and high-quality processing of the by reducing the area of contact with the mechanism for gripping the product and reliably draining the treatment solution. The installation can be built into an in-line or automatic line for processing or assembling products such as rollers, as well as working independently as an automatic machine, if there is a feeder. The invention The installation for the application of native coatings, comprising a housing, a van (gu for working liquor, a mechanism for transporting products to work positions, made in the form of a rotor with radially arranged holes, at the ends of which the heads are strengthened, a lodgment for supporting the product and the mechanism of loading and unloading the rotor, characterized in that, in order to improve the performance and ensure the specified quality of coating on the hollow products, the bath is made in the form of two chambers located in guides housing with the possibility of independent raising and lowering, and the cradle is made with a groove on the supporting surface and is located between the chambers.
