The USS ULTRA-BAGGER™ Bulk Bag Filling Machine

Dispense Pallet -> Fill -> Weigh -> Pack -> Convey -> Repeat

This FIBC (Super Sack) bulk bag filling machine features automatic pallet dispensing, bag hooks that retract toward the operator, automatic weighing, densification, and conveying. This station has it all – a turn-key package that saves on labor costs and measurement accuracy.

The USS ULTRA-BAGGER™ is our highest-rate bulk bag filling station. When you need to fill a lot of bags quickly, with little downtime and maintenance…this is the bagging station for you.

The elegant operation of this PLC-run station fills, accurately weighs, and packs your material in a single operation. Our patented densifier fills bags with up to 20% more product, saving space and efficiency in storage. Our densifier is so efficient that we have clients that stack bags on top of each other.

The USS ULTRA-BAGGER™ bulk bag filling station is available with or without conveyors. The unit is accessible from all four sides and can be oriented to fit your location.

Attachments for filling drums, boxes, and totes are available.

Our pallet dispenser will handle both wood and molded pallets. Pallets can be dispensed in-line or at a 90 degree angle. This option, with powered conveyor, will fully automate your operation.

Seamless Inflatable Cuff

The USS ULTRA-BAGGER™ Seamless Inflatable Cuff, manufactured of food-grade neoprene, expands against the inside of the bulk bag fill spout, sealing the opening to guard against product contamination and to control dust. All product contact points are constructed of stainless steel. An internal passage in the product fill spout allows the evacuation of dust during the filling cycle. A remote push button is provided to inflate and deflate the cuff.

Bag Inflation, Motorized Height Adjustment, Product Valve

A system to inflate the bulk bag before starting the filling cycle is housed within the air intake filter. An exhaust air filter assembly can be added or a connection to your existing dust collection system can be made to capture displaced air from the bulk bag.

The motorized height adjustment includes a motor, a gear reducer, lead screws with bronze nuts in each leg, and chain and sprockets to tie the system together. The upper and lower limits are controlled by a proximity switch.

The product valve to control the flow of your material is attached to your product source. A flexible hose then connects the valve to the bulk bag filling machine.
