Weight Checker Eliminate Monoblock Testing Equipment for Automated Lines

The Weight Checker Eliminate Monoblock Machine, developed by Tianjin ENAK Automation Equipment Co., Ltd., is a professional B-end Testing equipment designed for automated weight inspection and defective product rejection. It integrates precise weighing and real-time elimination functions, serving as a core quality control tool for food, beverage, and pharmaceutical packaging lines.

Product Overview

This Testing equipment combines weight checking and automatic rejection in one compact unit, saving workshop space and simplifying production line layout. It is compatible with various packaging types (bottles, cans, pouches, boxes) and can be seamlessly integrated into existing automated pipelines without disrupting workflow.

Product Performance

Equipped with high-precision load cells and a fast-response rejection mechanism, the Testing equipment achieves a weighing accuracy of ±0.1g and a maximum inspection speed of 200 products per minute. It features a 10-inch touchscreen interface with recipe storage (up to 100 product profiles) for quick parameter switching between different products.

High-Precision Weight Detection for Food, Beverage & Pharmaceutical Packaging

As a specialized Testing equipment, it delivers exceptional weighing precision that meets the strict standards of food, beverage, and pharmaceutical industries. Its high-sensitivity load cells (with 1/30000 division accuracy) can detect even tiny weight deviations—for example, identifying a 500ml beverage bottle that is 2g underfilled or a 100g pharmaceutical powder pouch with a 0.1g overfill. In food packaging, this prevents underweight products from misleading consumers and avoids overfill-related material waste. For pharmaceuticals, accurate weight checks ensure each dose meets regulatory requirements, eliminating risks of incorrect medication dosages. The Testing equipment also adapts to different packaging materials, from lightweight plastic pouches to heavy glass bottles, maintaining consistent precision across all applications.

High-Speed Detection for Automated Production Lines

This Testing equipment is engineered for high-speed operation, perfectly matching the rhythm of modern automated pipelines. With a maximum inspection speed of 200 products per minute, it can keep up with fast-moving lines—such as a beverage canning line producing 12,000 cans per hour or a snack packaging line handling 10,000 pouches per hour. Unlike manual weight checks (which average 20-30 products per minute and are prone to fatigue-related errors), the Testing equipment maintains stable speed and accuracy 24/7. Its fast-response rejection mechanism (triggered within 0.2 seconds of detecting a defective product) ensures no off-weight items slip through, even at peak production. This high-speed capability not only boosts overall line efficiency but also reduces labor costs by replacing manual inspection teams.

Networking Function for ERP/MES System Integration

The Testing equipment supports seamless networking, enabling integration with enterprise ERP (Enterprise Resource Planning) or MES (Manufacturing Execution System) platforms— a key advantage for data-driven quality management. Via Ethernet or RS485 ports, it automatically sends real-time inspection data (weight values, pass/fail results, defect counts) to the connected system. For example, if the MES system detects a sudden increase in underweight products, it can alert the upstream filling machine to adjust parameters, preventing a large batch of defective products. The Testing equipment also allows remote monitoring: managers can access real-time inspection reports and historical data via the ERP system, even from off-site locations. This integration streamlines quality tracking, simplifies audit processes, and helps enterprises identify production bottlenecks, laying the foundation for intelligent factory management.

High-Precision Weighing Module Manufacturing

The core weighing module of the Testing equipment undergoes rigorous craftsmanship to ensure accuracy. The load cells are sourced from international brands (e.g., HBM, Zemic) and calibrated in a temperature-controlled laboratory (±0.1℃) using standard weights traceable to national metrology standards. The module’s mounting structure is machined via CNC milling, with dimensional tolerance controlled within ±0.05mm to avoid mechanical stress affecting weighing accuracy. A shock-absorbing pad between the load cell and frame further reduces vibration interference from the production line, ensuring stable weight readings even in busy workshop environments.

Food-Grade Material Processing & Anti-Corrosion Design

All contact parts of the Testing equipment are made of SUS304 stainless steel, which meets FDA food contact requirements. The stainless steel undergoes a 3-step surface treatment: sandblasting to remove burrs, acid pickling for rust prevention, and electrolytic polishing to achieve a smooth surface (Ra≤0.8μm) that resists dirt accumulation and is easy to clean. The conveyor belt uses food-grade PU material (compliant with EU 10/2011 standards) that is non-toxic, wear-resistant, and resistant to oil and chemical cleaning agents. The IP65-rated conveyor part can withstand high-pressure water washing (80bar), making it suitable for hygiene-critical industries like dairy and meat processing.

Automated Rejection Mechanism Calibration

The rejection mechanism (pusher/flipper/air jet) is precision-calibrated to ensure reliable operation. During assembly, technicians adjust the rejection angle, force, and timing to match different product weights—for example, setting a gentle push force (0.5N) for fragile glass bottles and a stronger force (2N) for rigid plastic boxes. The mechanism is tested with 10,000+ simulated defective products to verify a 100% rejection rate without damaging 合格 (qualified) products. A self-diagnostic function is also integrated: if the rejection mechanism malfunctions (e.g., pusher stuck), the Testing equipment immediately stops the conveyor and alerts operators, preventing uninspected products from entering the market.

Q1: Can the Testing equipment adjust its weighing range for products of different weights (e.g., from 50g snack pouches to 2kg sauce bottles)?

A1: Yes. The Testing equipment supports a customizable weighing range (10g - 20kg) and can switch between different ranges via the touchscreen. For example, you can store a “50g snack” recipe with a ±0.1g tolerance and a “2kg sauce” recipe with a ±0.5g tolerance. Switching between recipes takes less than 10 seconds, making it easy to handle multiple product types on the same production line. We also offer optional load cell upgrades for customers needing to inspect extra-heavy products (up to 50kg).

Q2: How to solve the problem if the Testing equipment frequently generates false alarms (e.g., marking qualified products as underweight)?

A2: First, check if the conveyor belt is level—uneven belts can cause product position shifts and weight reading errors. Then, calibrate the weighing module using standard weights (we provide a calibration kit with each unit). If the issue persists, verify if the product is stable on the conveyor (e.g., irregularly shaped bottles may tip slightly)—adding a guide rail can fix this. Our technical team also offers remote calibration support; they can access the Testing equipment via Ethernet to adjust parameters and eliminate false alarms.

Q3: Is the Testing equipment suitable for wet or high-humidity environments (e.g., beverage bottling plants)?

A3: Absolutely. The conveyor part has an IP65 protection rating, which is dustproof and waterproof. It can withstand daily high-pressure water cleaning (common in beverage plants) and resist corrosion from water or cleaning agents. The control part (IP54) is installed in a sealed cabinet with a moisture-proof gasket to prevent internal component damage from high humidity. In tests, the Testing equipment maintained normal operation in 85% relative humidity (no condensation) for 72 consecutive hours, fully meeting the needs of wet production environments.

Q4: Can the Testing equipment’s rejection mechanism be customized for fragile products (e.g., thin-walled plastic bottles)?

A4: Yes. We offer three rejection options to match product fragility: 1) Air jet: Uses high-pressure air to blow lightweight/fragile products (e.g., thin plastic bottles) into the reject bin, with no physical contact; 2) Flipper: Gently flips products onto a side conveyor, suitable for medium-weight fragile items (e.g., glass vials); 3) Soft pusher: Equipped with a rubber pad to push rigid but scratch-sensitive products (e.g., matte-finish plastic boxes). Our sales team will recommend the most suitable rejection method based on your product’s weight, material, and fragility.
