On a stand (1), there are mounted brushes being coupled with a rotary motion source. The brushes are formed by radial brushes (2), wherein said radial brushes (2) are mounted opposite to each another. On the stand, there is further mounted a spectacles (B) holder (3), which is arranged on the stand (1) in adjustable manner relative to the radial brushes (2).

Description

Technical field

The invention is a device for mechanical cleaning of glasses by brushes.

BACKGROUND OF THE INVENTION

Glasses are usually cleaned using a tissue, sometimes impregnated with an active ingredient. Such a procedure does not generally remove dirt from the notches and creases between the glass and the frame. It is also known to clean entire glasses by immersing them in a solution. This procedure removes impurities from both the glass and notches and creases, but requires subsequent drying, depending on the solution used. A cleaning agent for cleaning glasses is known as described in patent CN 201285468 Y. It consists of a front brush retractable in a housing. The efficiency of the manual action of the windshield brush on the spectacle glass is considerably limited and is therefore not suitable for removing more soiling.

In the production of optical lenses where it is necessary to clean the treated glass blanks between operations, the cleaning is carried out for this purpose on the machine frame by means of electrically driven front brushes, as described in JP 4579633. Such an embodiment is only suitable for industrial use.

In contrast, the spectacle cleaning device described in U.S. Pat. No. 5,222,268 is suitable for use by the consumer for its own mobility. The arms of the U-shaped carrier are terminated by opposing brushes, one of which may be provided with a drive. This device is designed for individual cleaning of glasses by the consumer. It is not suitable for professional use, for example when assembling glasses or for opticians.

CZ 303 029 describes a device for mechanical cleaning of glasses by a front brush. The front brushes are arranged in pairs positioned opposite each other in the rack. Similarly, the device for mechanical cleaning of glasses by means of front brushes is described in U.S. Pat. No. 4,034,422. A disadvantage of these embodiments is that the front brushes have different pile speeds in the center and circumferentially. Towards the perimeter, the speed of the pile from which the brush is made gradually increases and thus its cleaning effect. This causes an uneven cleaning effect over the entire brush surface.

SUMMARY OF THE INVENTION

Apparatus according to the invention for mechanical cleaning of glasses by a brush, wherein the racks are arranged with brushes connected to a source of twisting motion, wherein the brushes are formed by radial brushes. Brushes arranged in this way treat the surface of the goggles at the same peripheral speed over their entire surface.

If the radial brushes are arranged opposite each other, the spectacle lenses are treated simultaneously on both opposite surfaces.

Advantageously, a spectacle holder is provided on the rack which is displaceably disposed relative to the brushes on the rack. This prevents the intervention of the human agent in the cleaning process.

If a liquid nozzle is placed on the rack, it is possible to influence the cleaning process with the applied selected liquid.

- 1 GB 304872 B6

The air nozzle located on the stand accelerates the drying of the glasses from the liquid used by the air nozzles.

Opposite pairs of brush rollers are arranged on the sides across the radial brushes for mechanical cleaning of the sides of the glasses. With this arrangement, the glasses are treated comprehensively.

In order to increase the cleaning effect, it is advantageous if the radial brushes and the brush rollers are composed of textile disks separated by spacers.

Fig. 1 is an overall schematic view of the arrangement of the device according to the invention; Fig. 2 is an overall side view in vertical section; Fig. 3 shows the front view of the device according to the invention; a brush consisting of textile disks separated by spacer rings is shown in Fig. 5 and a side view of the brush is shown in Fig. 6.

DETAILED DESCRIPTION OF THE INVENTION

The brushes 2 are rotatably mounted on the rack 1. The brushes 2 are connected to a source of twisting motion 21. The brushes 2 are formed by radial disks composed of textile disks 7, 7 'and spaced apart by spacers 71. The radial brushes 2 are arranged opposite each other so that glasses B can be inserted between them. On the stand 1 is arranged a holder 3 of glasses B, which is arranged in height relative to the brushes 2 on the stand 1. In order to exert a stroke movement of the holder 3 relative to the stand 1, the holder 3 is provided with stroke engines 32 whose pinions fit into the ridge JT mounted on the stand 1. Likewise, another form of stroke motion can be chosen. on the nut bracket. Screws or nuts would be provided with stroke motors 32. The holder 3 is provided with seats 3L for aligning glasses B In the lower part, a pair of liquid thimbles is placed on the stand 1

4. A pair of air jets 5 are disposed on the rack 1. At opposite sides of the radial brushes 2 are opposed pairs of brush rollers 6 for the mechanical cleaning of the sidepieces P of the goggles B. The brush rollers 6 are driven by motors 61.

As the selected procedure for cleaning glasses B, glasses B can be seated in the seats 31 in the holder 3, which is in the upper position. By the action of the air nozzles 5, the glass S is freed of undesirable dust. Subsequently, the holder 3 is moved to the lower position and the liquid nozzles 4 apply cleaning liquid to the glasses B. By successively lifting the holder 3 by the stroke engines 32, the glasses B are moved between the rotating brushes 2 and the dirt is removed from the glasses S and the related parts of the glasses B. After this phase is over By further lifting of the holder 3, the glasses B come into contact with air nozzles 5, which dry the glasses B with a stream of dry air. By removing the glasses B from the holder 3, it is ready to accommodate the other glasses B and thus to repeat the whole procedure.
