New bag inserter & uncuffer from WeighPack — The BI 600 automatic bag inserter and BU 600 automatic bag uncuffer.

WeighPack has launched two advanced packaging machines designed to automate the bulk bagging process. The BI 600 automatic bag inserter and BU 600 automatic bag uncuffer replace the manual insertion of bags into cases and the manual uncuffing and sealing of those bags prior to the closing of the cases.

Perfect for preparing bulk quantities of products such as pet food, frozen food, snacks, and wrapped candy for shipping, these units are designed to fit seamlessly into a bulk bag filling line with a case erector, bulk weigh filler, and case sealer, completing a fully automated system that forms, fills and seals cases, trays and bins, and the bulk-sized bags within them.

The BI 600 bag inserter dispenses film on a roll, cuts, seals, and then inserts the bag into a case. Once the product is weighed and filled, the case passes to the BU 600 bag uncuffer. The bag is then uncuffed from the case and folded over the product before the box is conveyed to the next phase of the packaging process. Bag sealing and vacuum assemblies are also available.

The BI 600 accepts 1 – 4mil film in roll widths up to 650mm and provides impulse sealing for leakproof polyethylene or laminated bags. The BU600 also accepts 1 – 4mil film with a bag fold over up to 610mm. Both units feature 304 stainless steel frames, SMC pneumatics, Omron servo motors with absolute encoders, Hiwin linear bearings, and 18-inch industrial PC panels.

WeighPack can customize a complete bulk bagging system to meet any weighing, filling, case erecting and case sealing need. Their V25 bulk weigh filler as well as the Boxxer case erector and EZ Tape case sealer from sister brand, EndFlex, are commonly combined with the EndFlex’ Z.Zag robotic palletizer to fully automate the bulk bagging process.
