Description

The device relates to the fields of building materials and the glass industry and can be used for the production of building, engineering and decorative laminated glass.

The well-known "Installation for pre-pressing a package of laminated glass" (Application for invention No. 94030110/33 according to IPC C03C 27/12, publication date of the application 05.27.1996), containing a housing with heating and vacuum systems.

The known installation, having as a vacuum system a large number of pneumatic chambers in the form of elastic diaphragms on their walls, is complex and cumbersome.

The closest in technical essence to the claimed device is the invention "A method of manufacturing a triplex and a device for its implementation" (Patent No. 2021220 according to IPC C03C 27/12 of 04/19/1991 g, published: 10/15/1994 g), in the description of which the device contains the furnace body with heating and evacuation systems of a triple-glazed unit consisting of two or more layers of glass alternating with layers of a polymer film inside the furnace, while the vacuum system outside the furnace contains a vacuum pump, an external hose and an external connector for this hose is docked, and inside the furnace there is a vacuum chamber, a fitting, an internal hose and an internal connector mounted on the inner surface of the furnace body and communicating with the external connector, the first end of the internal hose is connected to the internal connector, and its second end to the fitting mounted on vacuum chamber, the housing and its front door have a heat-insulating lining.

This known device partially solves the problem of reducing the dimensions of the vacuum chamber, which is implemented as a single-section tank for installing the formed triple-glazed windows in it.

Looking ahead, we note that in the claimed technical solution, this problem is solved more radically by using the local design of the vacuum chamber, covering only the double-glazed triplex, which can dramatically reduce the dimensions of the furnace and the device as a whole.

A significant disadvantage of the device according to the known invention is the absence in it of a number of important tools necessary to reduce marriage and obtain a double-glazed unit

- triplex (s-t) of high quality, namely:

- air cooling systems ct to quickly reduce the temperature ct upon completion of the sintering operation in order to avoid overheating and destruction of the polymer films used in the ct;

- upper and lower cassettes of quartz lamps in the s-t heating system for fast and uniform radiation heating of s-t;

- temperature, pressure, and humidity sensors, as well as a duty cycle timer;

- a modern device control system using an industrial controller that operates with sensors and a timer to accurately comply with the technological regime.

The technical result and the purpose of the claimed utility model is to eliminate the above disadvantage of the prototype, i.e. - reduction of rejects by about 10% and an increase in overall quality in the production of c-t due to more exact observance of the technological regime while reducing the dimensions of the device.

The device uses components and materials of wide application.

The housing 1 with the front door 1.1 and the roll-out table 9 are made of structural steel st. 3, and the heat-insulating lining 1.2 is made of asbestos-cement sheets fixed on the inner surface of the housing 1.

The internal hoses 3.6 and the vacuum chamber 3.1 in the form of a flexible hose are made of heat-resistant hoses (based on silicone, etc.) that can withstand temperatures of 160 degrees Celsius.

The vacuum chamber 3.1 in the form of a “blanket” is made of two sheets of silicone, one of which is placed under s-12, and the other on top of s-12.

Silicate glass 12.1,12.3 ... of different colors with a different transparency index from 4 to 10 mm thick is used as a consumable in the manufacture of ct 12. and polymer film 12.2 of the type PVB (polyvinyl butyral) or EVA (ethylene vinyl acetate).

The device operates as follows.

It is assumed that the device after manufacturing, debugged and put into operation for the production of multi-layer s-t 12, for example, building in accordance with GOST 30826-2001. Suppose that power is also supplied to input 11, and a control program is loaded into the system unit 10.2 of the ACS 10 that corresponds to the specified production process s-12. This program is beyond the scope of this technical solution and is not considered here. It should only be noted that depending on the initial consumables (type, quality, sizes), the ACS 10, based on the data of sensors 5, 6 and 7 and a timer 8 (it can be, for example, software in the ACS 10 itself), controls the on / off times heating systems 2, vacuum 3 and air cooling 4.

Suppose, for example, you want to get a safe three-layer glass - triplex 12 (from lat. - triple) two glasses 12.1 and 12.3, fastened with a polymer film 12.2, which provides increased strength, and with a strong breaking impact - keeping glass fragments from scattering. Currently, regardless of ply, the production of this toughened glass is called the production of a double-glazed window - triplex (s-t) 12.

Until the start of the ACS 10, the glass is cut, its edges are ground, and the surface is treated with isopropyl alcohol.

A polymer film 12.2 (for example, ethylene vinyl acetate) is placed on the first layer of glass 12.1, and a second layer of glass 12.3 is placed on it. etc. - with more ply.

Next, the thus-obtained double-glazed window 12 is connected with the vacuum system 3, more precisely with its vacuum chamber 3.1. When using a flexible hose (figure 2) in its longitudinal slot 3.1.1 insert the edges c-t 12 around its entire perimeter. When using the "blanket" (figure 3 under c-t 12 put the first silicone sheet, and on top of c-12 second. Protruding outside the c-t 12, the first and second silicone sheets are glued.

Then c-t 12 together with the vacuum chamber 3.1 is placed on the shelf 9.1 of the roll-out table 9. Through the internal hose 3.6 and through the nozzle 3.8, the vacuum chamber 3.1 is hermetically jointed with the internal connector 3.7. After that, the roll-out table 9 is pushed into the housing 1 and the front door 1.1 is closed.

Using the monitor 10.1, the keyboard 10.6 and the manipulator 10.7, the corresponding production process control program c-t 12 is activated. At the same time, the data of sensors 5, 6 and 7, which enter the system unit 10.2 through the controller 10.3, and timer 8 for the operator, are displayed on the monitor 10.1. The further process is carried out automatically and goes through the following main stages: evacuation, heating, aging and cooling. At the stage of evacuation, the vacuum pump 3.2 is turned on and, using elements 3.3 ... 3.8 of the evacuation system 3, a vacuum is created in the vacuum chamber 3.1 (in the working area). The task of this phase is the removal of air bubbles from the workpiece, and its preliminary formation. The recommended vacuum achieved in this case is up to "-095" bar. When evacuating a double-glazed unit with a layer thickness of 4 + 0.4 + 4 mm. Exposure will be approximately 15-20 minutes. The filter moisture collector 3.3, collecting condensate, provides longer operation of the vacuum pump 3.2. At the heating stage, it is carried out using elements 2.1 and 2.2, heating c-t 12 up to 100-130 degrees Celsius, to the temperature necessary for the polymerization of the film used. The main thing at this stage is to ensure uniform heating of the entire surface

The exposure time depends on the thickness of the resulting glass. Take into account the thickness and number of layers of glass, the thickness and number of layers of the film. For example, in the manufacture of a double-glazed unit with a layer thickness of 4 + 0.4 + 4 mm, exposure at room temperature will be 15-20 minutes. When working with glass thicker than 4 mm, it is necessary to increase the time of the entire working cycle by 5 minutes, for each mm of glass thickness difference.

Cooling occurs using elements 4.1 ... 4.5 of the air cooling system 4 with a constant discharge of “-0.95” bar to a temperature of +55 degrees Celsius, after which the vacuum is removed and c-12 cools naturally to a temperature of +45 degrees Celsius. At this stage, the production cycle is completed, and a message about its completion appears on the monitor 10.1, after which the roll-out table 9 is removed from the furnace body 1 with the finished product. If necessary, an appropriate protocol is printed on the 10.4 printer.
