Solids Handling Fill Bulk Bag Fillers

Bulk Bag Fillers

High-performance Equipment Built for Demanding Applications

NBE bulk bag filler systems are engineered for bulk material processing and bulk material packaging applications requiring high-performance operation; where reliable and repeatable duty cycles, rates, accuracy, and equipment effectiveness are crucial — regardless of process material characteristics. NBE bulk bag filler systems operate on a process-specific structural framework chassis. The NBE controls and automation architecture is integrated throughout the chassis to create a combined construction and controls infrastructure. This NBE integrated construction and controls infrastructure improves operator interaction with the system, provides more comprehensive and actionable performance data, and reduces total cost of ownership.

Features and Integration:

Bulk Bag Support Frameworks

The materials of construction and build specifications of NBE bulk bag filling systems enable bulk material processing operations to run production at designed rates without concern for unplanned downtime, inaccurate filling, or excess labor costs common with under-performing big bag filling systems. NBE bulk bag filler systems are engineered and constructed to withstand the harshest processing and packaging plant environments while providing exceptional performance in reliability and throughput.

Bulk Bag Loop Hangers

Safe, secure, and designed to minimize operator interaction, the bulk bag loop hanging systems on NBE bulk bag fillers reduce bag changeout cycle times while eliminating bag slip during the filling sequence. Engineered to accommodate varied bag dimensions, NBE bulk bag loop hanging systems simplify for the operator the bag hanging process, and aid in safe, accurate, and stable filling of bulk bags.

Base Configurations

NBE bulk bag fillers are engineered to ensure safe, accurate, and effective bulk bag filling; regardless of the bulk bag style, the process material characteristics, or the required fill rate. Designed to the specific performance requirement of each application; NBE bulk bag filler bases receive, and can densify, bulk bags on slipsheets or pallets. NBE bulk bag filling systems easily integrate with NBE indexing and accumulation conveyors, improving upstream and downstream process performance.

Bulk Bag Weigh Scale Systems

Engineered for bulk bag filling applications requiring highly accurate filled-bag weights, NBE bag weight scale systems enable bulk material packaging operations to fill bulk bags to an NTEP-certified, validated weigh accuracy of +/- .05% of the target total bag weight. NBE bulk bag filler weigh scale systems eliminate material waste and rework resulting from over-filled or under-filled bulk bags. The reliable, repeatable, highly accurate filled-bag weights from NBE bulk bag filling systems improves bulk material process uptime, performance, and yield.

Fillhead and Bag Spout Interfaces

The combination of process challenges solved by each NBE bulk bag filling system is never exactly the same. It stands to reason, then, that the design and configuration of each NBE bulk bag filler fillhead and bag spout interface is engineered to the specific requirements of each application. Regardless of difficult material flow characteristics, harsh operating environments, complex physical ergonomics of the operator, or material dust containment needs, NBE bulk bag filler systems will always deliver process performance advantages.

Cantilevered Bulk Bag Support Framework

Engineered for applications requiring medium to very high bag-per-hour fill rates, the NBE cantilevered bag support framework, with its 4,000-pound bag-load capacity, provides unobstructed access to three sides of the bulk bag filling station. Two unobstructed sides enable integration of indexing and accumulation conveyors. The third unobstructed side, the front, makes attaching and detaching the bulk bag easier and safer for the operator. Features such as automated height adjustment of the bulk bag framework, and automated bag hook positioning, can improve operator safety, and increase bag-per-hour fill rates, relative to manual operation.
Powered Cantilevered Mast Height Adjustment

For bulk bag filling operations where bags of varied heights are processed, the NBE cantilevered bag support framework with powered mast height adjustment enables safe and efficient re-positioning of the bag support framework. Mast height setpoints for multiple and differing bag heights are pre-set into the central HMI. When production requires bag height changes, the operator simply selects another setpoint at the HMI and the NBE bulk bag filler mast height automatically adapts to the new bag height parameters. The hydraulically powered mast height adjustment method provides faster adjustment speed and exceptional, 4,000-pound load capacity, relative to common ball screw adjustment mechanisms.
Four-post Bulk Bag Support Framework

Four-post bulk bag support framework designs are engineered for low to medium bag-per-hour fill rate applications. The build specifications of an NBE four-post bag support framework are determined by the performance requirements of the application. NBE fillhead configurations, weigh scale systems, bag stabilizing systems, dust control systems, framework height adjustment, and other process-optimizing features of the NBE four-post bag support framework, ensure safe, accurate bulk material processing and packaging.
Fillhead and Framework

For bulk material handling operations where legacy equipment requires a bulk bag filling interface, the NBE bulk bag fillhead and framework assembly directly mounts to existing filling equipment. The NBE fillhead and framework are engineered to the unique requirements of each application; even when high-performance materials of construction, or particular integration standards are specified. NBE fillhead and framework assemblies are typically used in low to medium bag-per-hour fill rate applications.

Other Bulk Bag Support Frameworks

Traversing Rear Bulk Bag Loop Hangers

The two, rear-positioned bag loop hangers, are pneumatically actuated, and guided by linear bearings, to move from their rear position on the bag support framework to their front position; well within the proper physical ergonomic reach of the operator. The traversing action of the two rear bag loop hangers occurs while the NBE bag support framework is safely in its stationary state; there is no concern for operator interaction with bag hook structures that swing down or rotate. The NBE traversing rear bag loop hangers are designed to keep operators in a comfortable posture and prevent walking on the equipment.
Auto-releasing Bulk Bag Loop Hangers

When the bulk bag filling cycle is complete, and the filled bulk bag is ready to proceed downstream, the four, NBE auto-releasing bulk bag loop hangers automatically open to release the bag loop from the hanger. The pneumatically actuated bag loop release greatly reduces bag changeout cycle times, and helps eliminate unsafe, manual bag loop release actions by the operator.
Manual Bulk Bag Loop Hangers

For applications where operator access to all four bag loop hangers is safe and efficient, and where the per-hour bag fill rate is low, the NBE manually operated bulk bag loop hangers provide a safe, and secure, method of attaching and detaching the bulk bag from the bulk bag filler. This NBE bulk bag loop hanger design eliminates the potential for the bag loop to slip out the hanger during the filling sequence, and is adjustable to accommodate multiple bag sizes.

Other Bulk Bag Loop Hangers

Platform Base

The platform-style base design of NBE bulk bag filler systems enables bulk packaging operations to easily process bulk bags on slipsheets or pallets. The NBE bulk bag filling system platform-style base contributes to a stable and square filled bulk bag; improving logistics and storage efficiencies, and reducing material waste.
Roller Conveyor Base

For applications where pallets or slipsheets are used to handle bulk bags, the roller conveyor base design of NBE bulk bag filler systems simplifies integration with upstream indexing conveyors and downstream accumulation conveyors. Designed for processing applications requiring medium to high bag-per-hour fill rates, the NBE roller conveyor base can easily be integrated with bag densification to improve bag stability and fill accuracy.
Densification Base

The NBE bulk bag filler system densification base is equally as effective when built into either the NBE platform base or roller conveyor base design. The NBE bulk bag densification system uses 3 Gs of high-speed, low-intensity vibration to settle process material in the bag to a dense, stable, and safe load. The vibratory action of the NBE systems is isolated from the deck and directed to the full width of the bulk bag; rather than just out from the center of the bag. The NBE densification base increases bag fill accuracy, reduces material waste and rework, and improves bulk bag handling and storage efficiency.
Pedestal Base

For applications where a pallet jack is required to remove filled bulk bags, the NBE pedestal base enables floor-level access for the pallet jack to the pallet fork openings. The pedestal base design features the full functionality and performance of the NBE cantilevered bulk bag support framework, including: automated height adjustment, automated bag hook positioning, hang-weigh scale system, and a 4,000-pound bag load capacity.

Other Base Configurations

Base-weigh Scale System

NBE base-weigh scale systems are engineered into the bulk bag filler framework using an isolation-mount design that protects the NBE weigh devices from damage and contamination that commonly effects the calibration and weigh accuracy of standard bolt-on, or third-party load cell assemblies. NBE bulk bag filler base-weigh scale systems are NTEP-certified accurate to +/- .05% of the total filled-bag weight. The NBE base-weigh scale system improves process accuracy and material utilization efficiency; eliminating rework and material waste.
Hang-weigh Scale System

The NBE hang-weigh scale system provides bulk material processing and packaging operations a highly accurate, highly reliable method for weighing and filling tall, or double-stacked bulk bags. The NBE hang-weigh scale devices are engineered into a weigh-bridge that is integrated to the bulk bag support framework and fillhead mast. The bulk bag hangs by taut straps from the weigh-bridge during the filling process. The NBE hang-weigh scale system design promotes stable material filling and NTEP-certified accurate weighing to +/- .05% of the total filled bag weight.
Pre-weigh Scale System

For applications with mid- to high-volume throughput requirements, the NBE pre-weigh bulk bag filling system provides consistent and accurate filled-bag weights. While the operator is spouting the bulk bag, the NBE pre-weigh filling system is simultaneously recharging the mast-mounted hopper and pre-weighing material in preparation for discharge and filling into the bulk bag. The NBE pre-weigh systems is NTEP-certified accurate to +/- .05% of the total filled bag weight at a rate of 30,000 pounds per hour.

Other Bulk Bag Weigh Scale Systems

Traversing Fillhead

Engineered to promote safe and efficient bulk bag spouting, the NBE traversing fillhead uses pneumatic power to bring the bulk bag fillspout forward from the machine center to a pre-set interface point; well within arm's length of the operator. The NBE fillhead support framework and fillspout stay in their horizontal orientation; providing a quicker, easier interface for spouting the bulk bag. The operator simply spouts the bulk bag to the fillspout and presses a button to return the fillhead and fillspout to their ideal bag-fill location. The NBE traversing fillhead enables operators to comfortably and efficiently spout the bulk bag rather than, with vertical fillspout designs, maneuver the entire bulk bag to align its horizontal bag spout to a vertical fillspout.
Inflatable Fillspout Bladder

The NBE inflatable fillspout bladder encircles the outside, lower ring of the fillspout opening. When the bulk bag is spouted, and the fillspout bladder is inflated, a dust-tight, retaining seal is created between the bulk bag spout and the fillspout opening. The NBE inflatable fillspout bladder reduces operator time to spout and loop the bulk bag, and reduces the release of migrant material dust. A manual inflate/deflate switch simplifies bag unspouting.
Bag Inflation Blower

For bulk bag filling applications where optimal filled-bag capacity and stability are required, the NBE bulk bag inflation blower system is engineered to force air into the empty bulk bag to ensure bag folds are removed and the bulk bag is properly pre-shaped for filling. Pre-inflation air is displaced by material during filling; bulk material is evenly filled throughout the bag creating a stable, accurately filled bulk bag. A 1-horsepower electric blower package provides the forced-air source.
Concentric Fill-and-Exhaust Tubes

To help prevent release into the work area of displaced, dust-laden air; and to aid in evenly dispersing process material within the bulk bag during filling, the NBE fillhead is engineered and constructed of two concentric tubes. The inside tube is an 8-inch diameter fillspout. The outside tube is a 12-inch diameter exhaust tube. During bag inflation the annular gap between the tubes delivers forced air from the bag inflation blower systems. During the material filling cycle, the annular gap exhausts displaced air and material dust to a vent port for collection and filtration.
Fillspout Flow Control Valve

The NBE fillspout flow control valve enables manual or automated adjustment of material feed rates; improving bag-full accuracy and reducing material waste and rework. NBE fillspout flow control valves are pneumatically actuated material flow mechanisms that enable variable adjustment of material feed rates; including bulk-feed to dribble-feed modes, and feed-start, and feed-stop modes.
Dust Collection

The NBE closed-cycle material dust recovery system collects and contains migrant material dusts and re-introduces recovered material back into the process operation. The NBE dust recovery system protects the operator and surrounding equipment and facilities from airborne dust. The air displacement outlet draws material from the bag spout interface for collection and filtration at volumes up to 300 CFM. The available, high-efficiency filtration stage recovers material particulate, as small as 1.00 microns, at a MERV11-rated efficiency.
Rigid Container Filling Adapter

For applications requiring filling of varied rigid bulk container types with an NBE bulk bag filling system; NBE container filling adapters enable safe and efficient filling of drums, totes, gaylords, and other rigid bulk containers. Engineered to the specific requirements of each application, NBE rigid container filling adapters are designed with the necessary materials of construction, controls and automation, and operator interface features to ensure optimal process performance measures in availability, throughput, and finished product quality; regardless of container type, duty cycles, or fill rates.
