- the housing bag containing the polycrystalline silicon inserted in the jig and the jig are lifted at the same time. Therefore, even if the storage bag is lifted, the jig can prevent the polycrystalline silicon from collapsing in the storage bag, so that the storage bag can be prevented from partially expanding from the state before being lifted. .
- the storage bag moves above the predetermined storage space and remains inserted in the jig until it is loaded into the storage space.
- the accommodation bag it is possible to prevent the accommodation bag from partially expanding until it is put into the accommodation space, so that the accommodation bag can be accurately put into the accommodation space.
- the size of the jig and the size of the storage space it is possible to prevent the storage bag from coming into contact with the partition plate of the storage space. Therefore, for example, when packing a storage bag into a box in which a storage space is formed, it is possible to avoid tearing of the storage bag.

Abstract
Description
<多結晶シリコン箱詰体の製造装置の概略構成>
図1に基づき、多結晶シリコン箱詰体G1の製造装置100の構成の一例について説明する。図1は、本発明の実施形態1に係る多結晶シリコン箱詰体G1の製造装置100の構成を示す斜視図である。製造装置100は、多結晶シリコン充填物FIが箱詰された多結晶シリコン箱詰体G1を製造する装置である。多結晶シリコン充填物FIは、多結晶シリコンS1が充填された収容袋B1をシールしたものである。
ここで、箱詰装置1において、収容ケース10に内挿されている多結晶シリコン充填物FIを箱BXに収容する際、多結晶シリコン充填物FIが吊り上げられ、箱BXの上方から箱BXに形成された収容空間20に収容される。
図3及び図4に基づき、収容ケース10について説明する。図3は、製造装置100で利用される収容ケース10の構成の一例を示す斜視図である。図3の斜視図2001は、側面体11と受皿15とが一体となっている状態の収容ケース10を示す。また、図3の斜視図2002は側面体11を示し、図3の斜視図2003は受皿15を示す。図4は図3のA-A断面図である。なお、図2から図9では、側面体11と受皿15とが一体となっている状態の収容ケース10において、側面体11から受皿15に向かう方向を下方向とし、受皿15から側面体11に向かう方向を上方向として説明する。
図1及び図7に基づき、本発明の実施形態1に係る多結晶シリコン箱詰体の製造方法について説明する。図7は、本発明の実施形態1に係る多結晶シリコン箱詰体G1の製造方法における収容ケース10及び多結晶シリコン充填物FIの動作を示す模式図であり、工程3001~工程3004を示す。なお、図7において、収容ケース10の各構成は簡略化して図示している。また、以下では、コンベアC1により製品が進んでいく方向を前方、前方とは逆の方向を後方として説明する。
本発明の他の実施形態について、図9に基づき以下に説明する。図9は、本発明の実施形態2に係る多結晶シリコン箱詰体G1の製造方法を示す模式図である。なお、説明の便宜上、前記実施形態にて説明した部材と同じ機能を有する部材については、同じ符号を付記し、その説明を繰り返さない。
本発明の一態様に係る治具は、多結晶シリコンが収容された収容袋を内挿するための内挿空間を形成する側面体と、前記側面体に配置され、前記側面体を吊り上げるための吊上部と、前記側面体の底部に着脱可能に配置され、前記収容袋を支える受皿と、を備え、前記側面体が吊り上げられ、前記受皿が前記側面体の底部から外れることで前記側面体の前記底部に開口部が形成され、前記収容袋を収容する収容空間に上方から前記収容袋が投入される際に、前記開口部が前記内挿空間から前記収容空間への前記収容袋の投入経路を形成する。
