Abstract
The present device comprises a bag filling apparatus which will clamp and hold a bag onto an output spout which forces in material such as pulverized or loose fill cellulose fiber used in insulation, and provides means for holding the bag in place, and providing a compressive force against the material as it is placed into the bag so that the material is forced into the bag and has substantial density when the bag is filled. The device includes means for automatically releasing the bag holder when the bag is filled a preselected amount.
Claims15
A bag filling apparatus comprising a filling spout of size to fit within the opening of a bag to be filled, support means for a bag to be filled comprising a first member for supporting a collapsed bag to be filled in a position extending from the filling spout, and a second member mounted with respect to said support means and positioned to overlie said first member, means on said second member comprising a packer head having an edge positioned adjacent said first member whereby a bag in collapsed condition only may be positioned between said edge and said first member, and said packer head having a surface facing the filling spout, and bias means resiliently permitting said packer head to move away from said filling spout as a bag is filled to thereby cause packing of contents in a bag at a density as desired.
Support and packer means for a bag to be filled from a spout through which low density compressible material is discharged under force, including a frame, a generally horizontal member movably mounted on said frame and movable to position to clamp at least one side of a bag to be filled against said spout to hold such a bag onto said spout, a packer head, means mounting said packer head for movement from a first position adjacent said spout wherein said head overlies a bag in collapsed unfilled condition and interferes with and resists expansion of a bag as material is forced into a bag held on the spout and supported on the generally horizontal member, said packer head being movable away from said spout as material fills a bag thereby causing packing of material into a bag, and bias means resiliently resisting movement of said packer head away from said spout.
