Product positioning
This product is a high-end dynamic weight-checking and rejection system specifically designed for lightweight, small-sized products. Its core objective is to achieve millisecond-level, gram-level precision in weight measurement and real-time sorting of each individual product (≤2 kg) even under extremely high production rates. It is a critical piece of equipment for enhancing the automation level of high-speed packaging lines and ensuring consistent product quality and compliance.
System Composition and Core Advantages
Ultra-high-speed, high-precision weighing module:
Challenges and Breakthroughs: At a speed of 80 meters per minute, the product spends an extremely short time on the weighing platform. This equipment features an ultra-high-frequency A/D sampling controller that acquires weight signals at a rate of tens of thousands of times per second. Combined with advanced real-time digital filtering and dynamic compensation algorithms, it can precisely “capture” the true net weight in an incredibly brief period, perfectly resolving the technical contradiction between “high speed” and “high precision.”
Millisecond-level response exclusion system:
It operates at a rhythm of 160 pieces per minute, utilizing a specially designed high-speed electromagnetic pusher. The pusher features swift and precise movements (with a response time as low as ≤20 milliseconds), ensuring that even with minimal product spacing, defective items—whether overweight or underweight—can be reliably directed into the rejection channel without any carryover or omissions.
Stabilization and Sanitization Design:
Structural stability: The scale body features a high-rigidity, low-inertia stainless steel structure that effectively suppresses both its own vibrations and external disturbances during high-speed operation.
Hygiene Compliance: Key contact areas are made of SUS304 stainless steel, featuring a smooth surface with no sanitary dead spots, making them easy to clean and disinfect, and fully meeting the stringent hygiene and anti-corrosion requirements of industries such as food, pharmaceuticals, and cosmetics.
Intelligent Human-Computer Interaction and Data Management:
Equipped with a large-size touch screen that displays real-time data such as weight, speed, pass rate, and production count.
Product parameters, upper and lower weight limits, and rejection action parameters can be easily set.
Built-in data statistics and storage functions support SPC process analysis and can connect to the network for data uploading (to MES/ERP systems), enabling full-process quality traceability.
Typical workflow
The products are conveyed through the preceding section, then pass through a high-speed alignment device to ensure proper orientation. They then enter the high-precision weighing section at a set speed. A super-high-speed A/D controller performs instantaneous sampling and computation. The weight data is compared with preset standards. If the deviation exceeds the allowable tolerance, the system precisely calculates and triggers a delay. When the product reaches the rejection station, a high-speed pusher acts instantly, accurately removing the defective item. Qualified products continue flowing to the next processing stage.
Core application scenarios
Food packaging: Net weight inspection and fill-level control for small snack bags, coffee sticks, seasoning packets, candies, pet food, and more.
Pharmaceutical and Healthcare: Inspection for missing tablets/pills in blister packs, missing vials/containers in small bottles/small pouches, and missing capsules in health supplement boxes.
Daily chemical products: Integrity inspection of travel-sized toiletries, small-pack skincare products, and single-use daily hygiene product packaging.
Electronics Manufacturing: Detection of missing or extra small electronic components and precision parts in bags.
Logistics sorting: Automatic weighing and grading of small e-commerce parcels.
Value created for the customer
Ultimate efficiency: With an ultra-high processing capacity of 160 pieces per minute, this system seamlessly integrates with high-speed packaging machines, completely eliminating production bottlenecks and maximizing output.
Superior Quality: Achieves 100% full inspection with ±0.3g-level accuracy even at high-speed operation, effectively eliminating compliance risks associated with “underfilling” and cost waste from “overfilling,” and significantly enhancing product consistency.
Cost reduction and efficiency enhancement: Fully automated operations replace manual spot checks, saving significant manpower; high-precision control directly reduces raw material waste, delivering a quick return on investment.
Data-driven decision-making: Comprehensive production data provides a solid foundation for process optimization, cost accounting, and quality traceability.
Robust and Reliable: The all-stainless steel construction and industrial-grade components ensure long-term stable operation of the equipment even in harsh environments, with easy maintenance.
In summary, this 2-kg high-speed checkweigher integrates ultra-high-speed processing, gram-level accuracy, a reliable and hygienic design, and intelligent data management—all in one device. It represents the cutting-edge of dynamic checkweighing technology. It is the ideal choice for modern smart factories striving for maximum production efficiency and flawless quality control, enabling refined production management.
