Description

Technical Field

[0001] The invention belongs to the technical field of glass tempering technology, and in particular relates to an automatic sheet loading system used in front of a glass tempering furnace. Background Art

[0002] Tempering technology is an important process in the glass deep processing industry. In order to improve the strength of glass and make it safer during use, glass tempering usually uses physical methods (i.e., borrowing the rapid heating and cooling principles of the tempering furnace) to form compressive stress on the glass surface. When the glass is subjected to external force, the surface stress must be offset first, thereby improving the bearing capacity and enhancing the strength of the glass itself. At the same time, it reduces the harm to people caused by fine particles formed after the glass is broken, thereby improving safety performance.

[0003] However, the cost of tempering glass is relatively high, because the rapid heating (electric heating) and rapid cooling (fan) of the tempering furnace are both achieved by consuming electrical energy, so how to efficiently improve the utilization rate of the tempering furnace is worthy of in-depth research.

[0004] There are two main types of tempering furnaces commonly used now: reciprocating and continuous types. Reciprocating tempering furnaces have a shorter heating section, which usually results in a longer heating time and lower output. The operators who load and unload the sheets also have to wait for a long time, resulting in a relatively low overall efficiency. Continuous tempering furnaces have a longer heating section, a faster operating speed and higher output. The operators who load and unload the sheets have a greater workload and often fail to keep up with the sheet arrangement. The equipment does not exert its maximum production capacity, and there is a certain gap between its overall efficiency and the standard value, resulting in higher production costs.

[0005] Therefore, designing a system that can realize automatic film loading and automatic film arrangement for glass tempering is a problem that needs to be solved by those skilled in the art. Summary of the invention
