ABSTRACT:
A two rail overhead conveyor device for meat processing is disclosed comprising an eviscerating platform conveyor, an entrance or feed rail, a lower rail for smaller carcasses and an upper rail for larger carcasses running parallel to each other above the eviscerating platform, a sensor to detect carcass size, a first rail switch connected to the sensor to direct the carcasses to either the upper or lower rail, an incline conveyor to raise the larger carcasses to the upper rail level, an indexing switch to regulate the flow of carcasses to the eviscerating area, a conveyor chain to propel the carcasses along the rails, and a second rail switch and detector to coordinate the transfer of eviscerated carcasses from the upper and lower rails to the exit rail. The conveyor chain comprises combination chain links having a drop finger and a spring loaded side finger with the side finger engaging and propelling the carcass trolley frames riding' on the upper rail while the drop fingers engage and propel the trolley frames riding on the lower rails.
An alternate embodiment utilizes a gravity rail drive rather than a conveyor chain to propel the carcasses to and from the eviscerating area with a conveyor chain functioning only to synchronize the movement of the carcasses over the eviscerating area with the eviscerating platform conveyor.
