ABSTRACT:
A bun laner sorts buns into a predetermined number of lanes, for providing buns to a packaging unit. The bun laner detects when some lanes are filling faster than other and closes those lanes while the other lanes fill. A vacuum may be used to hold buns in a filled lane in order to close the lane. An optical detection unit may be used to determine when a bun has been stationary at a certain position in the lane for a predetermined amount of time.
