MARCO launches MCW Rework Checkweigher to guarantee pre‑seal pack accuracy and protect brand standards
The MCW Rework Checkweigher is an intelligent, operator‑friendly solution that performs rapid pre‑seal weight verification and corrective adjustments, so every pack meets exact specifications before sealing. Designed for open products, the system automatically detects and diverts out‑of‑tolerance packs to a dedicated rework station, enabling quick corrections and ensuring compliant, consistent quality at speed.
Built to protect brands, cut waste, and boost efficiency
The MCW Rework Checkweigher safeguards brand reputation by delivering consistent, high‑quality products, reduces costly waste by correcting errors before sealing, and boosts efficiency through automatic detection and diversion of out‑of‑spec packs. With precision monitoring and operator‑friendly rework, manufacturers can maintain accuracy, cut costs, and keep customers satisfied.
How it works
- Pre‑seal rework for open products: Out‑of‑spec packs are diverted to a low‑friction rework conveyor and scale, where operators make fast, guided adjustments.
- High accuracy at line speed: Single‑point loadcell and teach functions capture precise weights with typical ±1 g accuracy and throughputs up to 90 packs per minute (product‑dependent).
- Operator‑friendly controls: Local product pre-sets, clear visual indicators, and simple belt tracking (no tools) streamline changeovers and daily operation.
- Sanitary, compliant design: Hygienic Grade 304 stainless‑steel frame options (tubular or open channel) and IP65 rating suit demanding food environments.
- Closed‑loop performance: Direct integration with MARCO Yield Control provides single‑point line start‑up, PC‑based reporting, and real‑time feedback to reduce giveaway and sustain accuracy.
As products travel through the line, the integrated conveyor scale captures each pack’s weight. Any pack outside tolerance is automatically detected and diverted to the rework station, where the operator confirms and corrects the weight using simple visual guidance. Confirmation sensors ensure rejected items are properly deposited before returning to flow, maintaining throughput without compromising quality.
