Article packing or unpacking apparatus, including two correlated driven conveyors, the first for articles and the second for moving cases through a fixed course having a horizontal section and with both conveyors having fixed orbits, the article conveyor being in a vertical plane above the horizontal section of the second conveyor; and article grippers are positioned by carrier bars engaged with the article conveyor, which grippers depend from the carrier bars in a lower reach of such article conveyor. A pair of control arms are individually secured to each carrier bar at different ends thereof to engage guides as the article conveyor is moved downwardly towards an inflection area so that the article grippers are presented on vertical axes as they are moved into, along with cases moving through the horizontal section of the case conveyor fixed course. The articles are deposited in a case, and the guides and control arms move the article grippers up away from the case with continued downstream movement of the conveyors.

In a case packer apparatus including a frame, a driven conveyor for moving empty cases through a fixed course having a horizontal section, said cases being moved at a fixed speed in said horizontal section, and a driven conveyor means having a fixed, closed orbit positioned in a vertical plane above said conveyor horizontal section, said conveyor means being driven at a greater speed than said fixed speed, a drive sprocket and a guide sprocket for said driven conveyor means, article gripper means, and carrier bars for said article gripper means operatively connected to and movable with said conveyor means, a driven article supply conveyor positioned below said driven sprocket, a pair of control arms for each said carrier bar individually fixedly secured to different ends of said carrier bar, to form carrier bar units, said driven conveyor means having a course extending downwardly towards said horizontal section at an acute angle thereto and then upwardly from an inflection area or zone at an acute angle thereto, said inflection area being the area of transfer of an article in relation to said driven conveyor and said conveyor means, and characterized by pairs of longitudinally spaced first guide means and second guide means on said frame to engage one of said control arms and control the angular relationship of said carrier bars and gripper fingers to the axis of said conveyor means as the carrier bar units are descending towards and into said inflection area and to engage the other of said control arms as its carrier bar moves away from said inflection area, said guide means each having an entrance end and an exit end, and said guide means operatively extending around the orbit of said driven conveyor means and being varied in spaced from such orbit to vary the positions of said gripper means in relation to a vertical axis.
