1. A machine for unstacking mattresses, mattress cores or foam panels, the machine comprising:
a belt mechanism having a conveyor belt, a first drive mechanism for driving the conveyor belt, a second drive mechanism for shifting the conveyor belt between a forwarded position and a retracted position, and a third drive mechanism for adjusting a height position of the conveyor belt;
a gripper mechanism having a gripper with needles and a fourth drive mechanism for moving the gripper between different height positions; and
a controller, the controller being configured to:
control the gripper mechanism to grip an end portion of an uppermost mattress, mattress core or foam panel of a stack by the needles and lift the end of the uppermost mattress, mattress core or foam panel,
control the second drive mechanism and the third drive mechanism to position a forward end of the conveyor belt below the lifted end portion of the uppermost mattress, mattress core or foam panel, and
control the first drive mechanism and the second drive mechanism to operate in a coordinated manner by shifting the conveyor belt towards the forwarded position while at the same time driving the conveyor belt in a backwards direction to draw the uppermost mattress, mattress core or foam panel onto the conveyor belt.
