Abstract: A simple and inexpensive method and apparatus are provided for weighing product, such as fruits and vegetables, with a separate, simple yet effective method and apparatus for sorting fruits and vegetables having the same characteristics. The weighing apparatus includes a pair of chains having inwardly extending pins engaging vertically elongated slots in lubricating plastic hour glass shaped roller segments. A flat bottom portion of each roller segment engages three rails of a stationary track while the pins engage the elongated slots and move the roller segments over the weighing mechanism. Two or more roller segments engage a fruit or vegetable at the same time, and the stationary track is notched at a load cell so that all of the roller segments supporting a fruit or vegetable operatively engage the load cell at the same time. The product sorter includes a contoured supporting base with a flexible belt on the base and in sliding engagement with it. The flexible belt includes a number of fingers spaced from each other in the dimension of conveyance. The belt may be formed in two sections, one having a roughened surface or shallow flights for engaging the fruits or vegetables. A number of ejectors, each comprising a rotary solenoid with a flipper, are spaced along the length of the supporting base to flex fingers of the belt and move a fruit or vegetable off of the belt and base when actuated.
