Abstract
An empty bag supplying apparatus used in a continuous conveying type bag-filling packaging machine in which the empty bag supplying apparatus receives empty bags and transfers these empty bags to gripper pairs of the bag-filling packaging machine that are moved continuously at a constant speed. The empty bag supplying apparatus includes downward-facing bag holding members and a reciprocating movement mechanism. The bag holding members hold the upper portions of bags. The reciprocating movement mechanism causes the bag holding members to reciprocate along an arc-shaped path and keeps the empty bags held by the holding members to be parallel to the direction of movement of the gripper pairs during the reciprocating motion. In a bag transfer region established in the arc-shaped path path, the speed of the bag holding members holding the empty bags is equal to the moving speed of the gripper pairs.
