空気を吹込んで拡張整形を行うのである。[Prior Art] Bagged products containing food and other fillings are not only cheap and easy to open, but also convenient for packaging and transportation, and have recently been applied to many products. Many automatic packaging machines that automatically perform packing have also been put into practical use. A bag shaping device is a device that expands and shapes the opening of the bag and the bag body to assist in supplying the filling when filling the bag.The conventional general shaping method is as shown in Fig. As shown in FIGS. 7 and 8, when the bag 10 with both upper side edges held by the chucks 9, 9 is sent, the upper and lower parts of the bag 10 are sucked from both sides by suction cups 11a, 11b and 12a, 1.
While sucking and expanding 2b, insert the conical pestle 1 from the opening.
3 is pushed in, air is blown into the punch 13 through an air hole 13a provided in the punch 13 to perform expansion shaping.

来ないと言う問題点がある。[Problems to be Solved by the Invention] However, since the conventional shaping device as described above is not provided with any means for holding the bag body 10 in a vertical state and correcting the inclination in the plane direction, as shown in FIG. As shown, the bag 10 is curved in an amorphous manner in the plane direction, and therefore the suction cup is not fully attracted to the bag surface, resulting in insufficient expansion. Particularly in the case of a self-standing bag such as a thick-walled plastic bag or aluminum bag with a folded part at the bottom, there is a problem in that the bag cannot be completely expanded to the bottom with just blown air because the bag is very rigid.
