DEVICE FOR EMPTYING DISPOSABLE FLEXIBLE CONTAINERS CONTAINING DIFFICULT-TO-POUR MATERIALS Russian patent published in 2005 - IPC

FIELD: material handling equipment, particularly for unpacking of articles or materials.

SUBSTANCE: device comprises body and unpacking tray. Body and tray may be connected one to another in working position and detached one from another. Box-like tray bottom is defined by two flaps moveable in opposite directions in longitudinal tray plane. Flaps may rotate in opposite directions in vertical plane. Flaps installed in initial lower position are attached one to another by edges thereof in tray bottom center. Each flap is pivotally secured to two bearing shafts located transversely to tray. Each longitudinal side wall of tray has a pair of through guiding slots symmetrical about vertical plane extending through transversal tray axis. Bearing shaft ends are inverted in guiding slots to create movement mechanism for blades cutting container bottom in longitudinal direction. Blades are arranged in row on upper surface of each flap along connected edges thereof. Body is made as a crate including horizontal rectangular frame, vertical posts connected to frame in end frame parts and horizontal transversal bars secured to upper post ends which are installed on frame so that upper bar surfaces may cooperate with bearing rods inserted in guiding slots. Connected to frame is guiding means extending along transversal frame axis. Guiding means is used to connect body to tray. Blade for cutting container bottom in transversal direction is movably installed on guiding means. Above blade is connected with rod end. Rod may be moved along guiding means and have length exceeding guiding means length.

EFFECT: simplified structure, reduced operational costs, increased efficiency due to applying force to material bridges inside container.
