Abstract
An apparatus and a method for individually bagging bundles into stretchable open bags. The apparatus comprises a bag stretching structure about which a bag can be turned inside out for wrapping an underlying bundle in response to continuous downward movement of the bag stretching structure once the closed end of the bag opposite the open end thereof has engaged the top surface of the bundle.
Claims24
An apparatus for bagging material into a stretchable bag having an open end, comprising a movable bag stretching structure having at least two stretching members displaceable between a first position for receiving the bag and a second position for holding the bag in a stretched state, at least two bag gripping members for releasably gripping the bag at said open end thereof, each of said bag gripping members being mounted on an associated one of the at least two stretching members and pivotable outwardly to turn the bag inside out over said movable bag stretching structure while the bag stretching structure is in said first position thereof, and an actuator for displacing said bag stretching structure towards a bag facing side of the material while the bag is held in a stretched state thereon such that a continuous movement of the bag stretching structure about the material causes the bag to be gradually inverted on the material as the bag engages the bag facing side thereof.
An apparatus for bagging material into a stretchable bag having an open end, comprising a movable bag stretching structure displaceable between a first position for receiving the bag and a second position for holding the bag in a stretched state, at least two bag gripping members for turning the bag inside out over said movable bag stretching structure while the bag stretching structure is in said first position thereof, and an actuator for displacing said bag stretching structure towards a facing side of the material while the bag is held in a stretched state thereon such that a continuous movement of the bag stretching structure about the material causes the bag to be gradually inverted on the material as the bag engages the facing side thereof, wherein said bag stretching structure includes a first pair of bag stretching columns and a second pair of bag stretching columns located on a downstream side of said first pair of columns, said columns of said first pair being located on opposed sides of a central longitudinal axis of the apparatus, said columns of said second pair being also located on opposed sides of said central longitudinal axis, and wherein said at least two bag gripping members include four bag gripping members, each bag gripping member being pivotally mounted to an associated one of said bag stretching columns for allowing the bag to be turned inside out over the columns.
