It uses static weighing principles to avoid error caused by belt movement. This machine can be used to check whether the individual weight of packaged items is within specification. It is suitable for online weighing of small products such as snack food, hardware screws, plastic parts, seasoning packets, toy components, electronic parts, furniture accessories, bathroom fittings, fasteners.
Crafted from premium food-grade stainless steel or industrial anti-corrosion materials, the chassis offers a cool, smooth metallic touch while providing rugged defense against harsh facility environments. The structural integrity supports intensive washdown cleaning protocols, meeting stringent hygiene standards in food processing and the durability requirements of hardware manufacturing. By halting the product momentarily, the load cell captures the exact mass with zero mechanical vibration, achieving an extraordinary detection accuracy of up to +/-0.5g. This precise static capture ensures that even the lightest micro-components are weighed with absolute certainty, minimizing costly product giveaway and optimizing your maximum throughput per minute. Whether you are dealing with brittle snack foods or dense metal fasteners, the static approach guarantees reliable consistency.
This video demonstrates the COSO Stop-And-Weigh Checkweigher, designed specifically for the lightweight products. Unlike dynamic weighing, our static system stops the product for a precise moment, eliminating vibration interference to ensure the weighing accuracy.
Watching the system in action, you will notice the quiet, deliberate pause of the conveyor belt. There is no disruptive mechanical hum or erratic bouncing of the packaged items. Instead, the item rests perfectly still, allowing the highly sensitive load cell to register the exact weight instantly. This visual evidence highlights how the stop-and-weigh logic outperforms continuous motion systems when handling delicate or micro-sized inventory. The immediate tactile response of the control screen and the swift, fluid motion of the sorting mechanism further illustrate the equipment's operational fluidity and structural reliability.
Modern production facilities require interconnected intelligence. This checkweigher supports seamless data transmission through Ethernet, RS-232, and RS-422 interfaces. It integrates effortlessly with existing PLC systems, enabling real-time recording and exporting of weighing data. Facility managers can monitor throughput statistics and weight deviations directly from their enterprise management systems, creating a synchronized, automated production loop that eliminates manual record-keeping errors.
At the heart of the machine is a highly responsive, multi-language touchscreen interface. The glass panel offers a crisp, glare-free display with immediate tactile feedback upon every tap. Operators can store multiple product recipe parameters, allowing for rapid changeovers between different batches of plastic parts or seasoning packets. Multi-level password permissions secure the system against unauthorized adjustments, while flexible over/under weight zones can be configured to match exact compliance tolerances.
Maintaining peak accuracy is straightforward thanks to the one-touch static calibration feature. The simplified interface guides users through the calibration steps visually, significantly reducing the learning curve for new operators. Furthermore, the core sensor design includes rapid troubleshooting diagnostics, immediately isolating faults to drastically reduce unexpected downtime and maintenance labor.
It uses the static weighing principle to eliminate errors caused by belt movement, guaranteeing that every measurement reflects the true mass of the item without kinetic interference, achieving up to +/-0.5g precision.
An inclined baffle is set up to prevent products from falling. The smooth, polished surface of the baffle gently guides irregular items—keeping them securely centered on the weighing platform.
The belt conveyor direction can be adjusted. Furthermore, the conveyor dimensions and working height are fully customizable to adapt to existing packaging lines, perfectly resolving installation challenges in tight or unconventional facility spaces.
When a defective product is detected, the belt automatically runs in reverse, rejecting the defective product into the reject bin. This mechanism features precise reject delay and duration controls, ensuring 100% accurate removal of out-of-tolerance items.
It can save space, and improve the production efficiency. By combining highly accurate static measurement with a compact footprint and intelligent automated sorting, the system maximizes throughput.
