Abstract

A bag placer apparatus having a number of improvements which, in combination, significantly increase the rate of placing valve bags upon a plurality of filling spouts to fill the bags with a flowable material. The apparatus comprises a pair of magazine apparatus for stacking the bags, a transfer apparatus for removing one bag at a time from the stack, a presenter apparatus for aligning the bag with the valve portion thereof in a precise location, and a picker-spouter apparatus which picks up the aligned bag, opens the valve and places it upon any one of one, two or three filling spouts. Each magazine supports a plurality of vertical stacks of horizontally positioned bags. The transfer apparatus alternatively de-stacks one bag at a time from each magazine and transfers it laterally to the presenter apparatus. The presenter apparatus includes means including a novel tilt arm for automatically transfering and registering each bag in precise position and alignment relative to the picker-spouter apparatus. The picker-spouter apparatus includes means for greater reliability in opening the valve of a bag and placing it securely on each filling spout. A novel two-step swing operation enables simultaneous swing and shuttle motion of the picker-spouter apparatus to increase bag placing speed.
