A rotating brush wheel positioned underneath the conveyor receives eggs and includes a first and second pluralities of bristles having, respectively, lesser and greater stiffness. An egg receiving reservoir exhibits a receiving lane positioned underneath and in alignment with the brush wheel for receiving and redirecting the eggs in a lane dedicated fashion to a subsequent egg handling operation. A plurality of spool bars are arranged in parallel extending and spaced apart fashion and defining a number of individual egg conveying lanes and each further include first and second spool bar portions secured in end-to-end fashion to establish an overall dimension. First and second drive supports are arranged at opposite ends of the spool bar portions, a third drive support arranged within the egg transfer mechanism and supporting opposing and intermediate engaging ends of each pair of spool bar portions. The intermediate drive support prevents sagging of the intermediate ends of the spool bar portions.
Abstract:
A conveyor and associated method for shock-sensitive products and the like, includes a conveyor member having at least one individual compartment for receiving a product therein, as well as upward and downward conveyor sections. An upper conveyor deflector deflects the conveyor member from the upward to the downward section. The compartment includes a first support surface configured for supporting the product in the upwardly directed conveyor section, as well as a second support surface configured for supporting the product in a downwardly directed conveyor section. The compartment also includes a bottom surface that supports the product during movement of the conveyor member over the upper conveyor deflector. The bottom surface has a curved shape, so that when passing over the upper deflector, the product deposited in the compartment is guided smoothly and gently along the bottom surface from the first support surface to the second support surface, such that critically damaging shock forces to the product are avoided.
