Abstract:
A multiple automatic packing machine comprising:slitter means for slitting a wide sheet-like packing material supplied from a take-up roll into a plurality of packing films;multiple automatic packing portions with said multiple packing portions comprising (a) heat sealing means for seal molding each of said packing films into an elongated bag-like configuration with a vertical heat sealer and a lateral heat sealer, and (b) material filling means for filling a material into each of said elongated bag-like configurations, said material filling means comprising a feed pipe with a filling screw disposed therein which screw is rotatable by a motor;wherein operations of said slitting means, said heat sealing means and said material filling means are repeatedly performed in a consecutive manner by said slitter means, said heat sealing means and said material filling means, respectively, whereby a plurality of packaged products are simultaneously seal molded automatically;wherein a packing film feeder for said multiple automatic packing machine is characterized in that feed pipes of said material filling means are arranged side by side in a line so that said motors for rotating said filling screws will not interfere with each other, and wherein each of said packing films which has been slit by said slitter means is conveyed toward and trained over a plurality of staggered direction-changing rollers which are shifted relative each other in the direction of the incoming slit packing film and such that longitudinal axes of said direction-changing rollers are oriented in a slanted direction with respect to said incoming slit packing films, wherein each of said incoming slit packing films is changed in lateral direction relative to the direction of the incoming slit packaging film and fed to said automatic packing portion.
