CZ2013692A3 - Device for mechanical cleaning of spectacle glasses - Google Patents

Abstract

The device is designed for mechanical cleaning of glasses (S) glasses (B) with a brush. Brushes attached to the torque source are mounted on the rack (1). The brushes are formed by radial brushes (2), wherein the radial brushes (2) are arranged opposite each other. Furthermore, a spectacle holder (3) (B) is arranged on the frame (1) and is adjustable relative to the brushes (2) on the frame (1).

Description

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 workpieces to be processed between operations, the cleaning is carried out for this purpose on the machine frame by relocating front brushes

This embodiment is suitable for industrial use only.

In contrast, the spectacle cleaning device described in U.S. Pat. No. 5,222 2-8 is suitable for its 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 303029 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, there is provided a device for mechanical cleaning of glasses by means of front cattails described in US patent 4,034 / 132. 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 displaceable 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 dispenser, it is possible to influence the cleaning process even by the application of the targeted liquid.

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. 2, an overall front view of the device according to the invention is shown in Fig. 3, an overall plan view of a device according to the invention is shown in Fig. 4;

A detailed view of a brush composed of textile disks separated by spacer rings is shown in Fig. 3 and a side view of the V 'brush is shown in Fig. 6.

An example of an embodiment 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 consisting of textile disks 7, 7 and spaced apart by spacers 71. The radial brushes 2 are arranged opposite one another so that glasses B can be placed between them S. A holder 3 for glasses B is arranged on the stand 1 and is arranged in relation to the brushes 2 on the stand 1 to be adjusted relative to one another. 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 engage a ridge 11 mounted on the stand 1. Likewise, another form of stroke motion can be chosen. and on the nut bracket. Screws or nuts would be provided with stroke engines 32. The holder 3 is provided with seats 31 for aligning glasses B in the lower part. A pair of liquid nozzles 4 is located on the stand 5 at the top. 2, opposite pairs of brush rollers 6 are arranged on the sides of the frame 6 for mechanically cleaning the siderails 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 up 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 get 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, the glasses B with their sides P get between the brush rolls 6 By further lifting of the holder 3, the glasses B come into contact with the 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.
