The invention relates to the glass industry and can be used in other areas where, when I change the ion treatment of products.

The purpose of the invention is to provide continuous processing of sheet glass.

The drawing shows a device for glass reinforcement, a general view.

The bath 1 for the active substance is equipped with a sheet loader composed of two, with individual drives, frame levers, including: the bottom 2, carrying two rows of rollers connected by a drive chain, and the top 3, a tagok with two rows of press rollers , both levers are pivotally mounted on the roller shaft of the roller table; the mechanism for moving sheets along the bath, including a stepped transporter 4, consisting of longitudinal beams, installed with the possibility (thanks to the approach to eccentric drive shafts) of plane-parallel movement relative to the level of the fixed beams resting on. bottom of the bath and chain, step-drying, conveyor Sj, unloader 6, representing, a descending air-spring gripping by a paired chain conveyor 7 of the cooling position, washing in the form, water tank 8 for washing with brushes 9, inclined conveyor 10 and stacker 11 sheets per rollergang-12, also of lever type with individual drive.

The operation of the reinforcement portion mechanism is as follows.

The next sheet from the roller table of the glass forming line runs over both rollers of the lower lever 2 loader. After that, both levers 2 and 3, turning on 90®, translate the sheet into a vertical plane with a change in its direction of motion to a vertical one, which it continues at a speed slightly exceeding the speed of the roller table (due to the increased diameter of the rollers of the lower levers 2).

When leaving the frictional engagement, the sheet is supported on the first row of nests of the toothed support rails of the fixed beams by means of a damping fall device, step-saving conveyors 5 cover the next sheet with successive spacer elements, advancing the approach under the sheets below

moving (according to the drawing on the left - up - to the right) transporting beams. The turnover of the eccentric shafts corresponds with the movement of each sheet by one step.

From the last nests of the toothed support rails of the fixed beams, a pneumatic spring-loaded grab and raised sheet moves to the washing position during air cooling.

A sheet lowered into the sink with an oblique drop below the water level is on the conveyor 10, which is carried to the rollers of the stacker 11, which returns the sheet to the roller 12.

Automatism of work of all mechanisms is provided by an electrical circuit blocking them, for example, with a breaker, by condition; the period of one revolution of eccentric shafts is equal to the cycle of fragments.

The next device ensures the passage of the defective sheet blanks past the ion exchange loading mechanism. the subsequent inclusion of the transverse, distant, conveyor.

For non-stop operation of the sheet-forming line, the ion-processing device is made in such a way that it can be excluded from the technological cycle, with one or two rolls of the roller table, which are removable, are returned to the place.

For ease of maintenance, the bath is installed on a base to be lowered with a fixed lid, which makes it possible to expose the cage without draining the bath, and also to be able to turn around the horizontal axis, which allows it to be quickly freed from debris after draining.

With a greater tape generation rate and a higher holding time in the ion exchange bath, the longitudinal size of the latter, as well as the transferred mass, is undesirably increased. To avoid this, the device is slightly modified, inputting additional parallel acting baths, for example, with mechanical rearranges, which are Sheets transferred to the vertical plane at the position of loading additional ion-exchange vatsna. In the same cases, if the shop layout permits, additional ( possible and in-depth) baths have

crosswise. The cross-shaped arrangement can be given to the main baths, especially since the operation of the line with the ionic treatment of only a part of the product is not excluded.
