Regular vibratory feeders, disc sorters, or other regular conveyors cannot feed some specific products due to their particular shape, sensitivity, or required orientation.
In this case, there is often the possibility of using a combination of an image-processing controlled robot with a pre-conveyor. The conveyor brings a stream of parts directly or backlit under the vision of the robot arm. Several robots can work simultaneously, depending on the desired speed.
Removal is done in a tracking motion and deposition can be stationary or in motion. Pre-conveyors can be various types of conveyors, vibratory hoppers, floor hoppers, and tray conveyors to provide the product for the robot.
