An automatic valve bag placer is disclosed which is constructed to sequentially remove valve bags from a bag magazine, manipulate the end flap of the bag for opening, open the valve and place the same on a fill spigot. An improved bag magazine and feeding assembly in which a plurality of trays are mounted on the elevator and feed stacks of limited number of bags onto a pick-off support structure ensures that bags are picked off one by one. The bag is oriented by a horizontal and then a vertical conveyor to a near vertical orientation, which orientation is retained thereafter until the bag is placed on the fill spigot. A pair of carriages and associated clamping means first pass the bag through a deflector assembly to orient the valve for opening, and then, after opening, the second carriage carries the bag to and inserts the same over the fill spigot. |
