従来、上述例のような被包装物を包装袋で被覆する装置としては、例えば、図 14に示すように、垂直方向に繰出し供給されるフィルム原反fの開口側周縁部 を左右の各チャック92,92で挾持し、各チャック92,92で挾持したフィ ルム原反fの開口側周縁部を左右方向に牽引して開口する。各チャック92,9 2で挾持したフィルム原反fを垂直方向に牽引すると共に、フィルム原反fの閉 塞側前後面を加熱ヘッド93で熱溶着し、同溶着部分の上位側を切断カッタ94 で切断して分離形成し、所定サイズに分離形成した包装袋Fを被包装物B全体に 被覆する。この後、各チャック92,92による挾持を解除して初期位置に上昇 復帰させ、続いて繰出し供給されるフィルム原反fの開口側周縁部を各チャック 92,92で挾持して被覆作業を継続する装置がある。 Conventionally, as a device for covering a packaged object with a packaging bag as in the above-described example, for example, as shown in FIG. The original film f f held by the chucks 92, 92 is held by the chucks 92, 92, and the opening-side peripheral edge of the film raw fabric f is pulled in the left-right direction to open. The original film f held between the chucks 92 and 92 is pulled vertically, and the front and rear surfaces of the original film f on the closed side are heat-welded by a heating head 93, and the upper side of the welded portion is cut by a cutter 94. The packaging bag F, which has been separated and formed by cutting with, and is separated and formed into a predetermined size, covers the entire package B. After that, the gripping by the chucks 92, 92 is released, and the chucks 92, 92 are raised and returned to the initial position. Then, the peripheral edge of the opening side of the film material f fed out and fed is gripped by the chucks 92, 92 to continue the covering work. There is a device to do.

しかし、上述のようにフィルム原反fの開口側周縁部を各チャック92,92 により挾持して開口し、各チャック92,92により挾持した包装袋Fを垂直方 向に牽引して被包装物B全体に被覆するので、各チャック92,92が初期位置 に上昇復帰するまで、フィルム原反fの繰出し供給を停止又は休止しなければな らず、作業能率が悪いという問題点を有している。且つ、被覆位置に供給される 被包装物Bの大きさに対応して包装袋Fの被覆サイズが大型となるため、包装袋 Fを牽引する各チャック92,92の昇降距離及び動作時間が長くなり、一つの 被包装物Bに対して包装袋Fを被覆するときに手間及び時間が掛かるという問題 点も有している。 However, as described above, the periphery of the opening side of the original film f is sandwiched between the chucks 92 and 92 to open, and the packaging bag F sandwiched by the chucks 92 and 92 is towed in the vertical direction to be packaged. Since the entire B is coated, the feeding and feeding of the raw material film f must be stopped or stopped until the chucks 92, 92 are raised and returned to the initial positions, which causes a problem of poor work efficiency. There is. In addition, since the covering size of the packaging bag F becomes large corresponding to the size of the object to be packed B supplied to the covering position, the lifting distance and the operating time of the chucks 92, 92 for pulling the packaging bag F are long. Therefore, there is also a problem that it takes time and time to cover one packaging object B with the packaging bag F.
