Product positioning
This product is a high-speed, precision dynamic checkweighing and rejection system specifically designed for small-sized, high-value-added products. It focuses on ultra-lightweight applications weighing up to 1.2 kg, delivering millisecond-level precision weight detection and automatic sorting for each individual item thanks to its high accuracy, rapid processing speed, and stable, reliable performance. It is a core piece of equipment for achieving “zero-defect” quality control and outstanding production efficiency in the high-end food, pharmaceutical, electronics, and precision manufacturing industries.
Core Design and Technical Highlights
High-precision technology under ultra-low measurement ranges:
Achieving an accuracy of ±0.3 g within an extremely narrow measurement range of ≤1.2 kg poses a significant challenge. This device employs a specially designed, low-range, high-sensitivity sensor paired with a high-resolution A/D sampling controller, along with a micro-dynamic compensation algorithm optimized specifically for lightweight products. This combination enables the device to effectively detect even the slightest weight changes, eliminate interference from minor environmental vibrations, and ensure outstanding repeatability and accuracy even under high-speed operation.
A balance system that combines high speed and precision:
The processing speed of up to 100 units per minute is perfectly balanced with stringent precision requirements. Through precise speed control and an optimally designed weighing section length, each product is provided with a sufficient and stable weighing time window. A high-speed A/D controller completes massive data acquisition and real-time processing within this window, achieving a seamless integration of efficiency and accuracy.
Agile and reliable rejection actuator:
To address the characteristics of small products—light weight and easy to scatter—this solution features a specially designed lightweight pusher head paired with an electromagnetic drive system that offers adjustable force and stroke. This ensures that the rejection action is swift, crisp, and precise, effectively guiding defective items into the designated channel while simultaneously preventing damage to product packaging or causing the products to topple over.
Hygienic Precision Manufacturing:
The entire machine is made of SUS304 stainless steel, with all contact surfaces smooth and seamless, fully meeting the hygiene requirements for the food and pharmaceutical industries as stipulated by GMP, FDA, and other relevant standards. The structure is compact and easy to thoroughly clean and maintain, making it well-suited for clean production environments.
Intelligent Control and Data Management:
Equipped with a user-friendly touchscreen interface, it displays in real time the weight deviation of each item, Statistical Process Control (SPC) charts, pass rate, production count, and more.
The powerful data traceability feature can store massive amounts of production data and supports seamless integration with MES/ERP systems via interfaces such as Ethernet and RS-232, enabling digitalization of quality management.
Typical workflow
The product is conveyed through the front end and its spacing is ensured → it smoothly enters the precision weighing section → a high-response A/D controller instantly completes high-speed sampling and weight calculation (resolution: 0.1 g) → the weight data is immediately compared with the preset standard → if the weight falls outside the allowable tolerance range, the system precisely calculates the signal delay → when a nonconforming product reaches the rejection station, a high-speed pusher is triggered instantaneously, accurately removing the defective item → conforming products then continue flowing to the next process stage (such as packaging or labeling).
Core Application Scenarios
High-end food products: Precise weight inspection of premium tea bags, coffee powder, nutritional supplements, pet treats, chocolate, and nut pouches.
Pharmaceuticals and Health Supplements: Defect detection for missing granules/bottles in small vials of oral liquids, aluminum-plastic blister packs of pharmaceuticals, bagged Chinese medicinal granules, and small-boxed health supplements.
Precision Electronics: Inspection for missing or extra small electronic components packaged in bags (such as chips, resistors, and capacitors) and mobile phone accessories.
Daily Chemicals: Inspection of filling volumes for sample-sized cosmetic products, travel-size toiletries, and disposable hygiene products.
High-value components: Weight sorting and integrity verification for precision metal parts and small packaging of jewelry and accessories.
The core value created for the customer
Exceptional quality assurance: Achieves sub-attogram (0.1 g) detection within an extremely narrow measurement range, virtually eliminating the risk of substandard products slipping through—thus providing robust protection for your brand’s reputation and meeting even the most stringent regulatory and customer standards.
Ultimate efficiency boost: With a high-speed processing capacity of 100 pieces per minute, this solution perfectly integrates with high-speed automated packaging lines, significantly boosting overall output and reducing the cost per unit.
Significant material savings: For raw materials with high unit prices, precise control within ±0.3 g translates into direct, quantifiable cost reductions and a short return-on-investment period.
Fully automated, unmanned operations: Replacing manual spot checks, eliminating human error and contamination risks, and achieving comprehensive automation and intelligent upgrades throughout the production process.
Data-driven intelligent decision-making: Provides real-time, accurate production data streams, offering robust support for process optimization, preventive maintenance, and quality traceability, thereby helping to build smart factories.
In summary, this ultra-small-range, high-speed, precision checkweigher—weighing just 1.2 kg—is a cutting-edge solution tailored for the precision manufacturing and high-end consumer goods industries, which strive for “zero-defect” quality and “maximum efficiency.” With its exceptionally high-precision control at ultra-low weighing ranges, fast and stable processing capabilities, and hygienic-grade design, this equipment has become a critical smart tool for ensuring product quality and enhancing market competitiveness.
