Abstract: A device for opening a series of bags in a stack. The device comprises a rotatable element having a substantially circular cross section. This element rotates and grabs a front side of the bag. Attached to the rotatable element is a first drive mechanism for rotating the element. In addition, a sensor is attached to the first drive mechanism. The sensor reads when the rotatable wheel grabs the bag. A second drive mechanism is connected to the first drive mechanism. This second drive mechanism drives the wheel into and back away from the bag stack. In this way, when the rotatable element rotates and moves into the bag, it grabs the bag. Next, it wraps the bag around the element so that the bag trips the sensor. The sensor triggers the motor to stop the element from rotating. In addition, the sensor signals the second drive mechanism to move the element away from the bag stack, to open the bag.
