Abstract
An automatic packaging machine comprises a spaced parallel pair of conveyor chains for transporting a plurality of mandrels. A pair of guide rails connected between the conveyor chains for slidably carrying each mandrel, so that a mandrel may be moved in a product transport position to a loading station. At the loading station, the mandrel is thrust forward to confront a box so that the product may be pushed into a box. The mandrel may be made wider to accept product without a precise alignment between mandrel and product or more narrow to fit the product into a box at the loading station. Two cam slots are provided to independently control the thrust position and the width of the mandrel. A stabilization support provides enough play to dissipate centrifugal force and thereby enable the machine to operate at a higher speed.

In an automatic packaging machine, the combination comprising a pair of spaced parallel vertical conveyor means mounted to turn about horizontal axes, said conveyor means establishing a path through said packaging machine, support means comprising a first pair of spaced parallel horizontal guide bars suspended between and traveling with said vertical conveyor means, platform means slidingly mounted on said horizontal guide bars for moving between transport and forward thrust positions along said established path, a second pair of guide bars carried by said platform means, said first and second pairs of guide bars being orthogonally related, a width adjustable transport mandrel comprising two side members mounted to slide toward and away from each other on said second pair of guide bars, whereby said mandrel has two axial motions along said orthogonal guide bars while being carried by said conveyors, and means for maintaining a predetermined adjustment of said width of said mandrel during said movement of said platform between said transport and forward thrust positions.
A high speed automatic packaging machine including a conveyor means for transporting mandrels in a given direction, orthogonally disposed rigid slide bar means having a pair of spaced parallel bars disposed parallel to an X-axis and perpendicular to said given direction, with said X-axis slide bar means being oriented relative to said conveyor means to thrust said mandrels forward to a loading position in at least part of a transportation excursion of said mandrels, a sliding stabilizer means supported on and slidably moveable along both of said X-axis bar means, said stabilizer means supporting a second pair of spaced parallel Y-axis bar means, a pair of carrier means slidably carried by said second pair of bar means, and a two piece width adjustable mandrel, each one of said mandrel pieces being carried on individually associated ones of said pair of carrier means, movement of said carrier means along said second pair of bar means causes said mandrel to divergently or convergently move between wide and narrow configurations.
An automatic packaging machine comprising means for transporting a plurality of mandrels around an endless path including at least a product receiving work station and a loading work station, means for moving said mandrels in directions transverse to said path in response to said mandrel being at particular work stations, means for adjusting a width of said mandrel in response to said mandrel being at particular stations, and means for independently operating said moving and adjusting means.
