Description

I

This invention relates to devices for treating products in liquids by dipping into baths, for example, during electroplating.

A device for coating products is known, comprising a series of baths arranged along the process, carriages placed on guides along the baths, traverses with a lifting mechanism, and mechanisms for horizontal movement of the carriages {ij.

However, the known device has a complex structure, due to the laborious provision of accurate centering of the movable guide bars with fixed guides fixed to the base, as well as the presence of two mechanisms for the horizontal movement of the carriages.

The closest to the invention to the technical essence and the achieved result is the device

for coating products containing a series of baths located along the process code, carriages with rods for processed products placed on rails along the baths, traverses with a lifting mechanism, and a mechanism for horizontal movement of the carriages 2.

The disadvantage of this device is the low reliability of its operation when transferring products from the bath to the bath.

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

IS

To achieve this goal, a device for coating products containing a series of baths located along the process, carriages with drafts for the products to be worked, placed on guides along the baths, traverses with a lifting mechanism and a mechanism for horizontal movement of carriages , each of the cross-arms is equipped with cams with counterweights, hinged at its opposite ends, interacting with the rollers located on the thighs with the thrusts being made with the possibility of space in the vertical plane.

FIG. 1 shows the proposed device, a general view; in fig. 2 the same in terms of; in fig. 3 is a section A-A in FIG. one; in fig. k - type B on fi 3

The device for coating products contains a series of baths 1, carriages A with rods 3 for the processed products 4, placed on guides 5 along the baths 1, traverse 6 with a lifting mechanism 7 and a mechanism 8 for horizontal movement of carriages 2. Each traverse 6 is equipped with cams 9 and 10 with counterweights, shirnirno fixed on, its opposite ends. Cams 9 and 10 interact with the rollers 11 located on the bars 3.

The lifting mechanism 7 consists of a hydraulic cylinder 12 and guide rails 13j that prevent the rotations 6 from turning around the axis of fastening of the hydraulic cylinder 12, T and gi 3 at the upper ends have stops 1t that prevent them from falling out of the attachment points to the carriages 2.

The device works as follows.

The carriages 2, moving along the guides 5, together with the belts 3 and the products 4 fixed on them from the mechanism of the horizontal movement 8, make a step motion in the direction of the arrows indicated on the drawings.

At the points of transition from one bath 1 to another, the lifting mechanisms 7 are installed, which by the hydraulic cylinder 12 lower the yoke 6 to the lower position, while the cams Ei 10 under the action of their counterweights are set respectively the cam 9 horizontally and the cam 10 vertically. Moreover, the cam 9, deviating from the action of the roller 11, is mounted below it. The tram 3, which was in the middle of the cross beam 6, is lowered into the bath 1. After the holding time of products k has expired, the hydraulic cylinder 1. raises traverse 6 to its upper position, which, interacting with rollers 11, raises two rods 3, namely traverses 6 located under cam 9 and in the middle 6. Then carriages 2 by means of horizontal movement mechanism 8 are moved one step.

At the end of the step motion, the carriage 2 interacting with

the cam 9 moves to the middle of the cross bar 6, and the carriage 2, which was in the middle of the cross bar 6, moves into the zone of action of the cam 10, driving it to a horizontal position.

After that, the hydraulic cylinder 12 lowers the yoke 6 together with the tami 3 down. The released cam 9 runs around the roller 11 of the next ti gi 3 and is installed below it. The cam 10 in the lower position of the crosspiece 6 under the action of its counterweight occupies a vertical position, the exit from contact with the roller 11. The proposed device simply

designs and allows you to securely grab and move rods with products when transferring them from one bath to another.
