Online Checkweigher JZ-150

Keypack Intelligent JZ-150 Online Checkweigher is an automatic weight detection and grading system engineered for high-speed production line inspection. It delivers ±0.1g–±0.2g accuracy at up to 100 pcs/min with a SUS304 stainless steel frame and 7-inch color LCD touch screen control. Ideal for pharmaceutical, food, toy, hardware, and chemical manufacturing lines seeking to replace manual weighing and improve output consistency.

Product Overview

The JZ-150 is a conveyor-based online checkweigher designed to perform automatic weight detection, overweight and underweight discrimination, and multi-grade weight sorting directly on the production line. Built with a single-chip microcomputer system and a proprietary filtering algorithm, the machine maintains stable detection performance even in demanding industrial environments.

The 7-inch large-format color LCD touch screen provides an intuitive operator interface with password-protected parameter settings, ensuring that only authorized personnel can modify inspection criteria. The system supports storage of up to 100 product test profiles, enabling fast changeovers across multiple SKUs without reconfiguration delays.

An automatic zero-point tracking system continuously compensates for environmental drift, maintaining reliable data output throughout extended production runs. The photoelectric empty-bag detection function and adjustable conveyor belt speed allow the machine to adapt to varying product flow rates. The buckle-type conveyor belt design simplifies disassembly for cleaning and routine maintenance, supporting food-grade and pharmaceutical hygiene requirements.

Keypack Intelligent (kunbupack) JZ-150 Checkweigher supports multi-language operation (default: Chinese and English; additional languages available upon request) and offers an optional three-light alarm system for real-time out-of-tolerance alerts.

Key Features and Machine Characteristics

• High-Accuracy Weight Detection: ±0.1g–±0.2g mini scale accuracy supports precise overweight and underweight discrimination, reducing product giveaway and non-conforming shipments.
• High-Speed Inspection: Rated up to 80–100 pcs/min, the JZ-150 integrates smoothly into fast-moving automated assembly lines and logistics sorting systems without creating bottlenecks.
• Automatic Zero-Point Tracking: Continuously compensates for environmental and mechanical drift, maintaining consistent and reliable detection data across long production shifts.
• Auto-Learning System: Adjustable conveyor belt speed combined with an auto-learning function allows the machine to adapt to different product weights and line speeds with minimal manual intervention.
• Photoelectric Empty-Package Detection: Automatically identifies and flags empty or missing-product packages before they pass through the weighing zone, reducing false rejects.
• 100-Product Data Storage: Stores up to 100 individual product inspection profiles, enabling rapid line changeovers and supporting multi-SKU production environments.
• Password-Protected Parameter Settings: Access control ensures that inspection thresholds and system configurations are managed only by authorized personnel, supporting GMP and quality management requirements.
• Easy Maintenance Design: Buckle-type conveyor belt allows tool-free disassembly for cleaning and inspection. SUS304 stainless steel construction supports washdown environments and meets food-grade and pharmaceutical hygiene standards.
• Air Sweep / Push Rejection: Dual rejection modes provide flexible non-conforming product removal suited to different package types and line layouts.
• Customizable Belt Height: Standard belt height of 750±50mm can be adjusted to match existing line ergonomics and conveyor heights.

Application Areas

• Food Industry: Online weight inspection of packaged snacks, condiments, frozen food portions, and bagged dry goods on high-speed filling and sealing lines; detection of underweight pouches or overfilled cartons prior to secondary packaging.
• Pharmaceutical Industry: Weight grading and non-conforming rejection of blister packs, bottled tablets, and sachets on GMP-compliant production lines; supports batch traceability and quality documentation.
• Toy and Consumer Goods: Automatic weight verification of assembled toy sets and multi-component consumer product kits to detect missing parts or incorrect assembly before shipment.
• Hardware and Industrial Components: Weight-based sorting and grading of fasteners, small machined parts, and packaged hardware items on automated assembly and logistics lines.
• Chemical Industry: Inspection of sealed chemical pouches, powder sachets, and small-volume liquid packages for fill weight compliance prior to palletizing and dispatch.
• Logistics and E-Commerce Fulfillment: Integration into automated sorting and dispatch lines for weight verification of outbound parcels, reducing shipping errors and customer complaints.
