    摘要: A packaging machine for forming pouches from a web of material having web tension control. A second pair of infeed rolls allows web tension through a sealing section to be controlled. An unwind reel is power-driven according to downstream web demand to thereby minimize tension spikes through the infeed section. The power unwind further minimizes the amount of festoon area needed. An entire packaging machine may be provided using modules. The registration-related operations of each section are independently controlled so that each module need only coordinate input and/or output speeds with interfacing sections.

    摘要: Pouch filling apparatus for carrying pouches through a pouch filler. The apparatus has leading and trailing clamps which are mounted on independent endless carriers. The endless carriers are driven at the same speed, but are controlled to maintain a set lag distance between the leading and trailing clamps. The lag distance may be adjusted to thereby adapt the apparatus for pouches of various sizes. The apparatus further incorporates a single retard arm and a single advance arm for moving the leading clamp between opened and closed pouch positions, respectively. The advance arm is located upstream of the pouch filler to move the leading clamp into the open pouch position for filling. The retard arm is located downstream of the pouch filler and moves the trailing clamp to the closed pouch position for sealing. The retard and advance arms are independently servo controlled to adapt the apparatus for pouches of various sizes and for continuous and intermittent operation.

    摘要: An apparatus and related method for feeding/turning successive cartons along the flow path of a packaging line is provided. An intermediate conveyor section between in-line feed and take away conveyors defines the substantially horizontal flow path. A plurality of elongated O-ring belts feed and turn the cartons. A separate side running chain having a straight operative run carries a plurality of extensible fingers; one selected finger engaging and capturing a leading corner of each successive carton to assist in turning. The O-ring belts are driven at differential speed. The combined feeding and turning action of the carton, assisted by retarding engagement of the carton corner by the finger assures positive and efficient feeding/turning of the cartons. A microprocessor is provided to control the driving of stepper/servo motors for the various components. The O-ring belts are driven by the single servo motor with a plurality of increasing size pulleys on a common shaft to provide the progressive speeds. The belts are elastomeric to provide positive gripping action along multiple lines of contact and ride in laterally spaced grooves in a flat plate. A sensor upstream of the conveyor section selectively actuates the retarding finger by an electrical solenoid for capturing the carton corner; each finger being V-shaped and mounted on a pivot pin. Each finger has depending guide fins on the outside portion for engagement with a track extending along the operative run for positioning in the retarded or extended positions.
