ABSTRACT:
Class workpieces, such as hog carcasses, of varying dimension, points of contour and shape are moved from storage on an overhead rail conveyer hanging vertically head down and are driven through break-up stations at a constant speed. Driven side belts moving at the same speed contact the carcasses in the work stations and hold them steady against oscillation. A saw or tool at each station is supported on a lead screw assembly for up and down movement. The lead screw is directionally and incrementally driven by a lead screw assembly at each station to locate each saw to perform work on the carcass. The saws at each station successively cut off the shoulder, loin-belly and ham as the carcasses move through the stations. The shoulder, loin-belly and ham fall by gravity onto conveyers when cut off by the saws. Manual means are provided to control the position of the saws as observed by the operator. Automatic means include activating an intelligent vision camera at each station to identify the location of the desired work point on each carcass for each saw. Camera data is calculated against the last prior location of the saw and a signal developed and fed to the lead screw mechanisms to drive the lead screws to locate the tools or saws at the desired work points on each carcass at each station whereupon the carcass moves through the saw at each station at the desired point of cut.
