紙容器１０１の縁巻部１０７に凹部を設けない場合は、充填ラインのレール１２１に載置して充填作業後の取出機１１０の爪片１１１による縁巻部１０７への挿入は、爪片１１１がレール１２１の上面と縁巻部１０７の下面との間に円滑になされないこと、縁巻部１０７を傷める虞があること等の不都合が発生する。
また、紙容器をレール１２１上にセットする場合も同様の不都合がある。 FIG. 13 is a side view for explaining inconveniences caused by a conventional paper container when no recess is provided in the edge winding portion of the paper container.
When the edge winding portion 107 of the paper container 101 is not provided with a recess, the insertion into the edge winding portion 107 by the claw piece 111 of the unloader 110 after the filling operation is performed by placing the claw piece 111 on the rail 121 of the filling line. Inconveniences such as not being smoothly made between the upper surface of the rail 121 and the lower surface of the edge winding portion 107 and the possibility of damaging the edge winding portion 107 occur.
In addition, when the paper container is set on the rail 121, there is the same inconvenience.

そこで、上記した不都合を回避するためには、レール１２１の充填位置、或いは払い出し位置には、縁巻部に設けた凹部として機能させる凹部１２４を、レール１２１側に設ける必要がある。
このレール１２１側の凹部１２４を介して、取出機１１０の爪片１１１を紙容器１０１の縁巻部１０７の下面に挿入する。これにより、紙容器１０１は、搬送位置、或いは充填位置にセットされる。
爾後、取出機１１０の爪片１１１を上昇させ、紙容器１０１を次工程に払い出し、搬送する。
これを図１４で示した。 Therefore, in order to avoid the above-described inconvenience, it is necessary to provide the rail 121 with a recess 124 that functions as a recess provided in the edge winding portion at the filling position or the dispensing position of the rail 121.
The claw piece 111 of the unloader 110 is inserted into the lower surface of the edge winding portion 107 of the paper container 101 through the recess 124 on the rail 121 side. As a result, the paper container 101 is set at the transport position or the filling position.
After clawing, the claw piece 111 of the unloader 110 is raised, and the paper container 101 is discharged to the next process and transported.
This is shown in FIG.

以上の構造では、ラインのレール上に凹部１２４を設ける必要があり、複数の箇所で充填等するのでは、レールに複数箇所凹部を設ける必要があり、また、凹部をレール側に設けるのでは、レールは専用となり、汎用性に乏しくなる。 In the above structure, it is necessary to provide the recess 124 on the rail of the line, and in order to fill at a plurality of locations, it is necessary to provide the recess at a plurality of locations on the rail, and when the recess is provided on the rail side, Rails are dedicated and lack general versatility.
