Abstract

An apparatus for transferring eggs continuously conveyed in spaced-apart, aligned relationship by a conveyor to a receiving station at which eggs are packaged according to their individual physical characteristics. A frame on which solenoid-actuated plungers are mounted is disposed adjacent the conveyor at the receiving station for releasing eggs having the same physical characteristics from the conveyor in a predetermined sequence at the receiving station. The frame is movable with respect to the receiving station according to the speed of the conveyor.

13. The apparatus recited in claim 12, wherein said first conveyor means is adapted to convey said eggs to said receiving station at a speed greater than that at which said second conveyor means conveys said eggs to said packing means.

14. An apparatus for delivering eggs to a receiving station of an egg grading apparatus at which the eggs are packaged according to their individual physical characteristics, comprising:

first conveyor means including a plurality of releasable egg-engaging means for conveying and delivering a plurality of eggs to said receiving station in spaced-apart, aligned relationship,

frame means movably mounted adjacent to said first conveyor means at said receiving station,

means, disposed on said frame means, for actuating said releasable egg-engaging means when said egg-engaging means are conveyed to said receiving station so as to release eggs having the same physical characteristics from said egg-engaging means in a predetermined sequence at said receiving station, and

means, coupled to said frame means, for varying the position of said frame means with respect to said receiving station according to the speed of said first conveyor means.

15. The apparatus recited in claim 14, wherein said actuating means comprises solenoid-actuated plunger means movable into the path of said egg-engaging means as said egg-engaging means are conveyed by said first conveyor means to said receiving station so as to open said egg-engaging means, thereby releasing eggs carried by said egg-engaging means in said predetermined sequence at said receiving station, said solenoid-actuated plunger means being mounted on said movable frame means.
