Automatic Vertical Glass Film Sorting System
LIJIANG Glass intelligent film sorting and storage system includes horizontal and vertical turning tables, vertical measuring tables, glass shuttle machines, film sorting and storage machines, and vertical and horizontal turning tables arranged along the glass conveying direction. Through the coordination and cooperation of various components, a series of processes such as horizontal and vertical conversion of glass, specification measurement, classified storage, and on-demand access are completed. The glass size in the process of processing is inspected by the vertical inspection table, and the glass is stored in the corresponding grid frame according to the system requirements. The system takes out the glass in sequence according to the process requirements for subsequent processing.

  1. The manual handling and classification storage links are reduced in the whole system, which greatly improves the efficiency and yield;
  2. Quick inspection, accurate positioning, intelligent classification storage and intelligent outbound;
  3. Optimize space utilization and reduce the space occupied by semi-finished products;
  4. Wide applicability, it can be used to store and classify before edging to improve the efficiency of edging; it can also be used to store and classify before tempering to meet the loading rate and process requirements of tempering furnaces, and it can also be used before hollowing to solve the automatic matching of insulating glass Production requirements.
Operating Mode

  • Pairing Mode
Online use, after multiple glasses with different matching requirements are sent to the racking system, the sheets are automatically paired according to the order required by the work order;

  • Sequential Mode
For offline use, after sending different glasses that need to be paired in a single rack into the racking system, the sheets are output according to the order of the work order;

  • Efficiency Mode
It is used offline before edging or color reeling, and the pieces are produced in order of small batches and sizes, and the number of edging openings and closings is reduced, and the edging efficiency is increased by about 1 to 3 times.

Automatic Laminated Glass Autoclave

Automatic Laminated Glass Autoclave

Automatic Laminated Glass Autoclave 1
Figure 1 Automatic Laminated Glass Autoclave 1
1. Combination operation process

When laminating glass, firstly choose a PVB film with a suitable glass width, and keep the film clean, avoid touching the corner film and glass directly with your hands, flatten the PVB film naturally, do not stretch it manually, and align it with the glass. There should be no sense of unevenness between the inner and outer films, and it is necessary to check whether the reserved marks overlap.

Then cut off the excess film. When cutting, keep the blade tilted, and leave 0.5mm-2mm film at the edge of the joint, which is to avoid shrinkage caused by film shrinkage.

After the film and glass are combined, put on a vacuum rubber ring and check the sealing strip. The tension around the glass should be uniform, and then cold draw the glass to remove the air in the middle of the joint, and the cooling time should not be short. in 5 minutes.

2. Glass preheating and pre-pressing process

After the glass is clamped with PVB film and the air is evacuated, the combined glass is preheated and pre-pressed.

There are three types of equipment for preheating and pressing operations. One is the preheating and pre-pressing box, which is favored by many manufacturers because of its simple equipment, small investment, and low energy consumption. However, there are also disadvantages to the preheating and pre-pressing box. The processing efficiency is low, and it cannot be adapted to industrial production; the transmission type vertical and horizontal preheating and pressing machines have high production efficiency and are suitable for glass deep processing factories. large-scale production.

The difference between transmission-type vertical and horizontal preheating and pre-pressing machines is that when the glass is placed to complete the preheating and pre-pressing process, the glass is placed vertically and the other is flat. When the vertical preheating and pressing machine is used to evacuate the glass, it has little effect on the arc of the glass; while the horizontal preheating and pressing machine are used to evacuate the glass because the glass is in a flat state, it will not be affected by its gravity and the pumping. Under the influence of vacuum pressure, it will affect the curvature of the glass. Therefore, horizontal preheating and pressing machines are used in the production of large-size glass.

3. Operation process of glass in the autoclave

The manufacturing process in the autoclave is the last in the production of laminated glass. The preheated and repressed glass must be treated at constant temperature and high pressure to make the PVB film and the glass laminate better bonded together.

The constant temperature and high-pressure treatment should be operated in an autoclave. Firstly, the semi-finished laminated glass bonded together should be isolated from each other, placed on a special stand for the autoclave, and made firm, and then the door of the autoclave should be closed tightly. Pressurize and inflate the kettle, and stop inflating the kettle when the pressure in the kettle reaches about 0.75MPa. Stop the inflation because the edges of the laminated glass are not bonded firmly, to make the space in the middle of the glass interlayer overflow under the action of pressure, so that the air will not enter the interlayer from the edge. When the temperature in the kettle reaches about 130°C, stop heating immediately and keep this temperature.

At this time, the laminated glass has been able to be bonded, and the second pressurization is carried out in the kettle. Since the glass has reached the bonding temperature, the pressurization will not cause air to enter the interlayer. When the pressure reaches 1.2MPa, stop the pressurization and Keep the pressure stable, and after 1h~1.5h, reduce the temperature in the kettle to 50°C, start to exhaust, and reduce the pressure in the kettle until the air is completely removed, then open the kettle door and push out the glass.

In addition, the processing process of laminated glass still has some finishing work, that is, inspecting the glass piece by piece, trimming the qualified products, cutting off the excess film around; Pressing, and heating.
