Wipotec / WIPOTEC-OCS Dynamic Weighing and Quality Inspection Systems

Technology of Monolithic Electro-Magnetic Force Restoration EMFR Weigh Cells

High-speed precision weighing in equipment engineered by Wipotec / WIPOTEC-OCS based in Kaiserslautern, Germany, relies on electro-magnetic force restoration EMFR principles.

Unlike conventional strain gauge load cells that measure mechanical deflection, an EMFR weigh cell functions as an analytical laboratory balance with electrodynamic load equilibrium.

When a product enters the weighing belt, minimal mechanical displacement is detected by an optical position sensor, and a voice coil in a permanent magnet field generates an opposing counter-force.

The monolithic sensor housing is milled from high-tensile solid aluminum, eliminating mechanical backlash and ensuring sub-millisecond response times.

Active Vibration Compensation AVC Architecture and Dynamic Weighing Reliability

In real manufacturing plants, nearby rotary packaging machinery, industrial compressors, and transport forklifts generate continuous vibrational noise that impairs weighing accuracy at high speeds. Wipotec / WIPOTEC-OCS developed proprietary Active Vibration Compensation AVC technology.

Integrated acceleration sensors continuously measure ambient support frame vibrations and apply digital hardware filtering to the measurement signal in real time.

Consequently, the checkweigher preserves laboratory weighing precision even when installed directly on common production platforms without massive isolated foundation blocks.

Modular High-Speed Checkweighers HC-M Series for Packaging Hall Automation

The flagship dynamic checkweigher Wipotec / WIPOTEC-OCS HC-M series represents a versatile modular platform for filling and packaging suites operating at belt speeds up to 250 units per minute.

The system integrates infeed, weighing, and outfeed conveyors driven by independent electronically regulated drives.

The rigid steel frame prevents structural twisting under heavy operational loads, while tool-free conveyor belt quick-release mechanisms streamline sanitary wash-down without hand tools.

The digital controller maintains full statistical tracking of package weights, automatically feeding offset signals to upstream filling machines.

High-Throughput Checkweighers HC-A Series and Gentle Product Reject Systems

For ultra-fast beverage bottling lines, pharmaceutical blister machines, and continuous packaging operations running up to 650 packages per minute, Wipotec / WIPOTEC-OCS manufactures the premium HC-A series.

The mechanical layout incorporates lightweight ceramic bearing sets and brushless servo drive motors with microsecond synchronization between adjacent belt segments.

For sorting packages with weight deviations, synchronized electrodynamic swing gates and soft divert flap mechanisms redirect off-spec products smoothly, preventing breakage of thin-wall glass containers, cosmetic tubes, and cartons.

Combined Quality Assurance Systems: Integrated X-Ray Scanners and Metal Detectors

Compliance with modern food safety and pharmaceutical regulations demands multifaceted quality verification within a single automated line passage.

Wipotec / WIPOTEC-OCS integrates dynamic checkweighers with SC series industrial X-ray inspection modules and high-sensitivity metal detectors into unified compact stations.

The sub-millimeter X-ray imaging sensor reliably detects non-metallic foreign bodies such as glass splinters, stone, and bone fragments while verifying package contents completeness. Machine housings feature sloping stainless steel surfaces meeting IP69K wash-down standards.

Pharmaceutical Serialization and Multilevel Packaging Aggregation TQS Stations

To fulfill stringent international track-and-trace mandates for pharmaceutical distribution, Wipotec / WIPOTEC-OCS developed specialized TQS (Traceable Quality System) machines.

The systems execute direct serialization coding by printing sharp DataMatrix codes on carton flaps via thermal inkjet or laser printing heads. High-resolution machine vision cameras immediately verify code grading against ISO standards.

The equipment then coordinates bundle and case aggregation, generating shipping pallet labels and transmitting validated batch data records to plant database architectures.
