Blanks are not fed correctly into the machine.
Irregularities in the blank from the carton supplier.
The mechanical forces of opening the case and folding the flaps.
Transporting the formed case through the machine.
Powered magazine infeed belts precisely govern the delivery speed of the case blanks to the pick-up arm, avoiding the first jam point when blanks are not fed correctly. The magazine also provides easy, walk-in loading.
A system of multiple separation retainers ensure the blanks are spaced correctly and enter the machine one at a time, in a vertical upright position precisely at the time the pick-up arm is ready to capture the blank.
A hinged pick-up frame with eight vacuum powered suction cups firmly grips two panels of the case to ensure square case creation. While the case is held at a 90 degree angle all flaps are folded and locked in the shape.
All flaps are folded while the case remains stationary and utilizes only a single pusher bar to slide the squared case into the exit side belts, maintaining 90 degree angles and minimizing the resistance forces on the case.
Synchronized motors and the spring load feature of the dual-side exit drive belt accounts for variability in the width of the case, maintaining the square footprint without crushing the case as it is pulled across the bottom closing unit.
When does it make financial sense to move from hand erecting boxes to purchasing an automatic case erector? Find out how much you could be saving by downloading our calculator.
This poster gives you a snapshot on how to identify a square case. If cases are not square you run the risk of problems down the line like loosing 30% of your stacking strength and product damage.
