ABSTRACT:
An automatic bag filling and packaging system includes a filling apparatus for filling a bag with a material through a bag mouth, and a bag supply apparatus for supplying the filling apparatus with individual bags. The bag supply apparatus has separating means for separating a chain of interconnected bags, each of which is sealed along its entire periphery, into individual bags at perforations between adjacent bags. The filling apparatus includes unsealing means and mouth widening means. The unsealing means includes a cutting member which, while a bag sealed along its entire periphery is being held, is operable to cut off one side edge of the bag to provide the bag with an unsealed mouth. To prevent a material introduced into a bag from adhering to the mouth widening means during a filling operation, the widening means includes a suction device for opening the bag mouth by attracting the outer surface of the bag near the cut edge, two widening members thrust into the bag from the mouth and then separated from each other to widen the mouth, and a suction device for attracting the outer surface of the bag to maintain the mouth in the widened state so that the widening members can be withdrawn from the bag prior to filling. Also provided is positioning means for positioning each bag in X and Y directions before the bag is received by the filling apparatus.
