The SWF brand of Case Erectors (CE 420T and CE 425G) automatically select, erect, square, and seal the bottom flaps of regular-slotted (RSC), and halfslotted (HSC) corrugated cases. The CE 420T seals cases with tape and is designed for speeds up to 20 cases per minute. The CE 425G seals cases with a pre-determined glue pattern and designed for speeds up to 25 cases per minute. Speeds dependent upon the model configuration and case size.
Case Erecting Machine Operation
To operate the case erectors, a stack of cases is placed in the case magazine. Vacuum cups select a case from the top of the stack and index it to the erecting station. Once in the erecting station, the case is opened and erected using the vacuum cup system. The front and rear minor flaps are folded inward 90˚ and then the major flaps are folded 90˚. The case is then transferred by a mechanical walking beam onto the top and bottom driven feed belts. The belts transport the case through the taping head on our CE 420T, which applies tape to the leading panel approximately 2” (51mm) from the bottom. As the tape is applied, a series of two rollers and a brush “buff” the tape the ensure its adhesion to the case. The severed end remains secure in place and is applied to the leading panel of the next case in line. As the case leaves the taping section, the rear pressure rollers follow the trail end, applying final compression to the case. Our CE 425G applies hot-melt adhesive to both minor flaps and then moves into compression for squaring the case.
