Description

TECHNICAL FIELD [0001] The present invention relates to a packaging bag forming apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a packaging bag molding apparatus and a molding method, and more particularly, to a packaging bag molding apparatus and a molding method for shaping a packaging bag having a opening portion at one end into a determined shape.

Generally, solar cells are classified into crystalline type and thin film type according to raw materials and technology. Crystalline type is higher in production cost than thin film type, but has high light conversion efficiency and occupies most of the current solar cell market.

Poly-silicon, a raw material for crystalline solar cells, is a small silicon crystal that converts light energy into electrical energy in solar cells.

These polysilicon succeeded in mass production through researches of fine chemical companies such as Dow Corning in the 1950s, and with the growth of the semiconductor industry in the 1960s, high purity polysilicon products were developed. In the early days, only a small number of companies produced and used most of them in CPU (Central Processing Unit) substrate. However, since 2005, the solar cell market has been rapidly expanding along with the development of the solar industry.

In the polysilicon production process, carbon melt-reduction of silicon, that is, silicon silicon extracted from quartz is mixed with a carbon compound and heated, is added to a furnace using metal silicon (MG-Si) And a Siemens system in which refined polysilicon is obtained by chemically reacting with trichlorosilane.

In addition, there are FBR (fluidized bed reactor), MG-SoG (Solar Grade Metallurgical Silicon) and VLD (vaporto-liquid deposition).

In general, when the above processes are performed, chunk-type polysilicon or chip-type polysilicon in which the rod-shaped polysilicon and the cylindrical polysilicon are broken to an appropriate size are finally completed.

The polysilicon thus produced is supplied to the customers through a packaging process. The packaging process includes filling and sealing the polysilicon quantities in the bag for each shape and size of the polysilicon.

However, in order to store the polysilicon in the packing bag, the folded packing bag is formed into a predetermined shape and is seated on the tray. In the past, this process has been performed manually by the operator, There is a problem that the shape of the molded bag varies depending on the operator. In addition, there is a problem in that the difference in the tact-time required depending on the skill level of the worker is large and the productivity of the logistics is deteriorated.
