【実施例】
以下、本発明の実施例を添付図面を参照にして説明する。本発明に係る丸形包装袋における培養基を充填した包装袋の袋口の折込装置の概略構成とその動作については、図１から図１６で示した培養基を充填した丸形包装袋による袋口折込装置の全体構成を示す概要図にて述べる。
この実施例では、袋口折込装置の本体枠１の上端側には培養基Ｂを充填した丸形包装袋Ｐを供給する搬送機構からなる無端状の搬送コンベア２が設けられており、この場合、前記無端状の搬送コンベア２としては、前記本体枠１の両端にロ−ラ３が設けられ、このロ−ラ３に無端状の搬送ベルト４が掛け渡されており、前記一方のロ−ラ３には、そのロ−ラ３を回転駆動する駆動用モ−タ５が連結されて構成されている。[0018]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to the attached drawings. The outline configuration and operation of the folding device of the bag mouth of the packaging bag filled with culture medium in the round packaging bag according to the present invention, the bag mouth folding by the round packaging bag filled with culture medium shown in FIG . 1 to FIG. This will be described in a schematic view showing the overall configuration of the apparatus.
In this embodiment, on the upper end side of the main body frame 1 of the bag-opening folding device, there is provided an endless conveyer 2 comprising a conveying mechanism for supplying a round packaging bag P filled with culture medium B. In this case, As the endless conveyer 2, rollers 3 are provided at both ends of the body frame 1, and an endless conveyer belt 4 is stretched around the roller 3, and the one roller A driving motor 5 for rotationally driving the roller 3 is connected to 3.

また、前記袋口扁平支持機構６を基準として前記搬送コンベア２の搬送方向下流側には、前記袋口扁平支持機構６によって扁平状態に製袋される袋口Ｐ１部分を前記包装袋Ｐ内に充填されている培養基Ｂの上面側にほぼ沿って折り返す第１の折込保持機構１２が設置されており、この実施例における第１の折込保持機構１２は、丸形包装袋Ｐ内に充填される培養基Ｂの高さ寸法より若干高い位置関係において、搬送機構である搬送コンベア２に載せられて搬送される培養基Ｂが充填されている丸形包装袋Ｐの移動に連れて、前記袋口扁平支持機構６によって扁平状態に起立した形態にて製袋されている袋口Ｐ１部分を前記丸形包装袋Ｐ内に充填されている培養基Ｂの上面側にほぼ沿って折返し案内するほぼ平坦状の規整保持プレート１３によって袋口Ｐ１の上面側から押圧規整するように構成している。[0021]
Further, on the downstream side of the transport direction of the transport conveyor 2 with reference to the bag mouth flat support mechanism 6, the bag mouth P1 portion to be bag-formed into a flat state by the bag mouth flat support mechanism 6 is placed in the packaging bag P. A first folding and holding mechanism 12 is provided which folds back substantially along the upper surface side of the culture medium B being packed, and the first folding and holding mechanism 12 in this embodiment is packed in a round packaging bag P. In a positional relationship slightly higher than the height dimension of the culture medium B, the bag mouth flat support is accompanied by the movement of the round packaging bag P filled with the culture medium B which is placed and conveyed on the conveyer 2 which is a conveyance mechanism. A substantially flat arrangement for guiding and folding the bag mouth P1 portion, which is bag-formed in the form of being erected in a flat state by the mechanism 6, substantially along the upper surface side of the culture medium B filled in the round packaging bag P By the holding plate 13 It is configured to press-regulating from the upper surface side of the bag mouth P1 Te.

次いで、第１の折込案内機構１２と袋口整形機構１７の各シリンダ１５，２０を復帰作動し、搬送コンベア２の搬送ベルト４の送りに沿って培養基充填包装袋Ｐを下流側に送り出すことにより、その包装袋Ｐの移動に連れてその袋口Ｐ１部分が前記第１の折込保持機構１２の規整保持プレート１３によって袋口Ｐ１の上面側から押圧規整され、前記包装袋Ｐ内に充填されている培養基Ｂの上面側にほぼ沿って折返し案内されながら送り出され、これにより、その包装袋Ｐ内の培養基Ｂの上面側に倣って折り返すことが可能となり、綺麗に揃った状態に袋口Ｐ１を水平状態に折り込むことができる。[0036]
Then, the cylinders 15 and 20 of the first folding guide mechanism 12 and the forahead shaping mechanism 17 are operated to return, and the culture medium-filled packaging bag P is sent downstream along the feed of the transport belt 4 of the transport conveyor 2 When the packaging bag P is moved, the bag mouth P1 is pressed from the upper surface side of the bag mouth P1 by the adjusting holding plate 13 of the first folding and holding mechanism 12 and filled in the packing bag P It is fed out while being guided by being folded back almost along the upper surface side of the culture medium B, whereby it becomes possible to fold back along the upper surface side of the culture medium B in the packaging bag P, and the bag mouth P1 is neatly aligned. It can be folded horizontally.
