ABSTRACT:
A system for forming a plurality of discrete objects into a stack is disclosed which system includes a frame having a top, a bottom and sides; a conveyor associated with the frame and having an end edge for dispensing discrete objects, a first support mounted on the frame near the end edge for receiving objects from the end edge and having an opening with a width smaller than the width of the objects, a first actuator operably connected to the first support for moving the first support between first and second positions relative to the end edge; a second actuator operably connected to the first support for moving the first support between upper and lower positions relative to the frame; a second support mounted on the frame beneath the first support having a width less than the width of the opening in the first support; a third actuator operatively connected to the second support for moving the second support between high and low positions, the second support high position being higher than the first support lower position; a third support mounted on the frame at a position higher than the second support low position and having an opening wider than the width of the second support; a fourth actuator operatively connected to the third support for moving the third support between a first position beneath the first support and a second position; a sensor for determining the number of discrete objects in a stack, the sensor being operatively coupled to the to the third actuator; and a controller for controlling the first, second, third and fourth actuators. A method of using the system is also disclosed.
