Abstract
The invention is applied to an apparatus for filling storage boxes with lemons or other articles. The articles are first diverted from a conveyor into a measuring and collecting bin. When articles fill the bin to a level which will fill a box beneath the apparatus, a photoswitch stops the conveyor to prevent overfilling of the bin. The photoswitch also tilts a chute at the bottom of the bin whereby the entire contents of the bin are emptied into the box. Although the level of articles in the bin falls below the beam which operates the photoswitch, an internal time delay in the photoswitch holds the conveyor in stopped position and it also holds the chute in tilted position until sufficient time has passed for the box to be filled. Immediately thereafter, the chute is returned to upright position, the conveyor is restarted, and an unfilled box takes the position of the filled box.
