The empty bag supply device described in Patent Document 1 pulls out the bottom side of the empty bag in the cassette box while adsorbing it by a plurality of suction pads, and also pulls it out on the supply sliding plate of the inclined surface to be the supply side of the bag packing device. In an empty bag feeder configured to be able to supply, a bag retainer that can move up and down together with the suction pad at a position close to the opening side of the empty bag from the suction pad at approximately the same height as the suction start position of the suction pad. A short feed auxiliary belt and a wide long feed belt, which are equipped with a plate and are vertically movable between the feed roller mounted on the upper end side of the bag and the cassette box, are reversed from each other. It is deployed and configured to do so.

そして、当該空袋供給装置では、カセット箱内の最上空袋の底部側に吸着する吸着パットを上方に移動させながら空袋の底部側を上方へ取り出す際、その吸着パットの近傍となる空袋の開口部側寄り上面を袋押さえ板により押さえることになって、2枚取りや次の空袋がずれることなく整然と有効に取り出すことができることになり、また、取り出した空袋がよじれたり、カセット箱側で位置ずれが生じていても、幅広い送り出しベルト上に安定良く供給することができて、先端側を上下動させることができる送り込み補助ベルトにより空袋がめくれるようなことなくそのまま整然と取り込んで良好に送り出すことができることになり、カセット箱からの取り出しと滑板側への送り出しを性能良く有効に行なうことができる。 Then, in the empty bag supply device, when the suction pad adsorbed on the bottom side of the top empty bag in the cassette box is moved upward and the bottom side of the empty bag is taken out upward, the empty bag becomes in the vicinity of the adsorption pad. By pressing the upper surface near the opening side with a bag holding plate, it is possible to take out two empty bags in an orderly and effective manner without shifting, and the empty bags taken out can be twisted or a cassette. Even if there is a misalignment on the box side, it can be stably supplied on a wide range of delivery belts, and the feed auxiliary belt that can move the tip side up and down allows the empty bag to be taken in as it is without being turned over. It can be sent out satisfactorily, and can be taken out from the cassette box and sent out to the sliding plate side effectively with good performance.
