Description

  The present invention relates to a glass separating apparatus for separating and taking out glass from devices used for equipment such as solar cell modules, liquid crystal televisions, plasma televisions, and the like. The present invention relates to a glass separation device for separating and taking out the glass from a processed product in which a sheet containing a resin is adhered to a glass-like glass.

  In general, for example, a solar cell module is configured by attaching a sheet containing a resin to a plate-like glass and surrounding it with a metal frame. The sheet is mainly composed of a resin protective material on which a solar cell element is formed and a filler for adhering it to glass. A power terminal box and a wiring cable are attached to the back surface of the protective material. Solar cell modules that are no longer used due to their end of life are discarded, but in recent years, they have also been recycled. In this case, the terminal box and the cable for wiring are removed, the frame body is removed, and the required members are recycled. Further, from a sheet of glass containing a resin attached to a plate-like glass, the glass is separated and recycled, and the residue is melted or the like, and a required metal is taken out and recycled.

By the way, it is not easy to separate the glass from the plate-like glass on which the resin-containing sheet is adhered, because the sheet is bonded with a filler, and an apparatus capable of easily processing this has been developed. . Conventionally, as this kind of glass separation apparatus, what was published by Unexamined-Japanese-Patent No. 2011-173099 (patent document 1) is known, for example.
As shown in FIG. 9, this conventional glass separation apparatus conveys a processed product W having a sheet S adhered to a plate-like glass G by a conveyor 100. Crushing between the provided top roller 101 and the bottom roller 102 having a flat outer peripheral surface (the crushing process in FIG. 9A), and then placing the heater 103 on the processed product W softens the filler. Then, the broken pieces of glass G (referred to as glass pieces Ga) are scraped off from the sheet S with the cutting edge of the blade 104 (separation step in FIG. 9C).
