ABSTRACT:
An apparatus for discharging the contents of bags containing flowable material includes a frame, with a pair of bag spikes mounted generally parallel to, and coplanar with, one another on the frame. A pair of bag pans is movably mounted on the frame so as to be engageable with the bag spikes. Each of the pans is selectively pivotable around a respective axis defined by each of the bag spikes. The bag pans are movable between a first, load/unload position wherein the bag pans are out of engagement with the spikes, and a second, engaged position wherein the bag pans are in engagement with the spikes. A knife assembly is provided that includes a knife arm having a first end pivotably mounted to the frame, and a second end upon which is disposed a knife member. The knife assembly is pivotable between a severing position wherein the knife member extends between the bag pans, and a rest position wherein the knife member is out of the plane defined by the bag pans. A bag pan drive mechanism is mounted on the frame, and is adapted to move the bag pans between their load/unload and engaged positions. A knife actuator mechanism is also mounted on the frame. The knife actuator mechanism is adapted to move the knife assembly between the severing position and the rest position. A bag pan pivot mechanism is also mounted on the frame, and is adapted to selectively pivot the bag pans about the axes defined by the bag spikes.
