Description

Technical Field [0001] The present invention relates to a vacuum insulator manufacturing system using a gravity pressing shuttle,

The present invention relates to an automatic vacuum insulator manufacturing apparatus using a gravity pressing shuttle unit, in which a vacuum molded material that is loaded in a multi-layered manner is pressed in the gravity direction by the weight of the weight plate of the pressurized shuttle unit to prevent flow during vacuum forming, And more particularly to a vacuum insulator automatic manufacturing apparatus using a gravity pressurizing shuttle unit in which a mold opening / closing operation of each layer of a pressurizing shuttle unit is easily and simply controlled in a compact structure.

Generally, a vacuum insulator is sealed in a high vacuum state by inserting a core material into a shell material, vacuum-pressing it, sealing the inlet of the shell material, and providing a high thermal insulation performance due to the vacuum space between the porous core materials.

However, due to the characteristics of the manufacturing process, when the internal core material having a low density and a large volume is accommodated in the envelope and put into a vacuum chamber and all the air inside the vacuum chamber is removed by using a vacuum pump, However, since the core material pressing process is performed depending on the pressure inside the vacuum chamber, it takes a long time to form the vacuum degree in the vacuum chamber.

 Conventionally, in Japanese Patent Laid-Open Publication No. 10-1442747, there is proposed a drying / combining low vacuum chamber which has a heating means for drying and which can perform a primary low vacuum process using a low vacuum pump, A high vacuum chamber capable of secondary treatment of a high vacuum as a final target by using a separate high vacuum pump and a conveyance carrier including a workpiece in each of the low vacuum chamber and the bottom portion inside the high vacuum chamber for drying, And a carrier automatic rotation transfer device for continuously supplying and discharging the product while rotating the rotation of the product in a rotation direction of the vacuum vacuum chamber and a vacuum insulation panel VIP), it is possible to make more rapid and continuous automatic production in the vacuum molding required in the manufacturing process, Technologies that can contribute greatly to the efficiency and quality of processing have been registered.

However, according to the prior art, the molding time is delayed due to the compression molding of the heat insulating core wrapped with the sealing film depending on the degree of vacuum of the vacuum chamber, and the sealing film adheres unevenly to the surface layer of the core material, Therefore, it is difficult to closely adhere to the installation surface during the field construction, resulting in irregular space, resulting in dew condensation, and a problem that the sealing film is easily damaged due to the concentration of the load at the point of local point contact with the installation surface.

In order to solve such a problem, a separate pressing means is provided at the upper portion of the chamber. However, since the pressing force is temporarily fixed to the chamber, a temporary pressing force is provided during the vacuum forming process. , There was a phenomenon of deterioration of the forming precision, and excessive carrier and chamber sizes were excessively increased due to excessive thickness in the multi-layered multi-layer loading.
