ABSTRACT:
An automated bag filling mechanism particularly adapted to handle reclosable zipper lock-type plastic bags fed into the machine in a bag chain has a bag opening station, a filling station, a bag reclosing station, and a bag separation station, all successively serially arranged in the machine along a transport path in which the bag chain is conducted through the machine. Mechanical means are provided at each station to perform the functions of that station. The mechanical means are sequentially actuated and controlled by the movement of individual cam members keyed for rotation to a continuously driven rotary driveshaft. Means are provided to assure proper alignment or registration of each bag of the chain before the various work stations of the filling mechanism, despite tolerance variations in bag size, slippage in the drive devices, and/or slack development in the chain.
