Intermittent container discharge device in continuous-filling packaging system

Abstract

A discharge device which, in a retainer type continuous-filling packaging system, extracts full bags (bags filled with contents) from retainers that are continuously fed at a constant speed and discharges these full bags after converting the movement of the bags into an intermittent movement of a plurality of rows. The discharge device includes a full-bag holding member conveying device and a product-conveying conveyor. In the full-bag holding member conveying device, numerous full-bag holding members that have therein the full bags and are disposed at equal intervals are moved in one direction along a ring-form track (or race-track path) which has a pair of parallel sections, and during this movement, the full-bag holding members are moved continuously at a constant speed on a bag entry side of the parallel sections and are moved intermittently a specified distance (which is a distance equal to an integral multiple of an attachment spacing of said full-bag holding members) on a bag exit side of the parallel sections. The product-conveying conveyor receives the full bags in a plurality of rows discharged from the full-bag holding members and conveys these bags “as is” in a plurality of rows. On the bag entry side, the discharge device continuously receives the full bags from the retainers that are continuously conveyed at a constant speed; and on the bag exit side, the discharge device discharges the full bags in a plurality of rows from the full-bag holding members that are stopped
