2. Description of the Related Art Conventionally, as an apparatus for laying a package as described above, for example, as shown in FIG. 18, both side edges of a film raw material f formed of a synthetic resin into a tubular shape are adsorbed. The raw film f held by suction at 80 and 80 and held by the adsorbers 80 and 80 is thermally welded in the width direction by the heating head 81, and the raw film f is cut in the width direction by the cutting cutter 82. The two bags F are separately formed. At the same time, the adsorbent 80,
80 is moved to open the mouth Fa of the bag body F sucked and held by the suction elements 80, 80 in the left-right direction. Thereafter, the bag body F sucked and held by the adsorbers 80 and 80 and the box body G supplied to the lower part of the same position are relatively moved in the vertical direction, and the bag body F sucked and held by the adsorbers 80 and 80 is put in a box. There is a device laid inside the body G.

[0003]

However, in the above-described apparatus, one bag F is separated and formed by heat-welding and cutting the tubular film web f in the width direction, and then the opening of the bag F is formed. Part F
Since a is opened by the adsorbents 80 and 80 and laid inside the box G, the work of separating and forming one bag F and the work of laying the bag F take time and effort. In addition, a mechanism for thermally welding the film web f and a mechanism for opening the bag F must be provided, which not only complicates the process and configuration of the entire apparatus, but also allows one bag F to be formed. There is a problem that the work time when laying inside the box G is long and the work efficiency is poor.

If the bag F in a gusset-folded state is used instead of the bag F described above, the bag F can be laid in a state corresponding to the inside of the box G. In this case, After the cylindrical film f is welded and cut in the width direction to separate and form one bag F, the bottom four corners of the bag F must be heat-sealed. Not only takes time and effort to form body F,
Since the sealing operation of the bag F is complicated, the unit price of the bag itself is high, and there is a problem that the packaging cost is high.

In view of the above problems, the present invention pushes a sheet-shaped package into a container and lays the package so as to cover the inside of the container. It is an object of the present invention to provide a packaging body laying device capable of performing the operation efficiently, saving labor and improving efficiency.
