Keypack Intelligent Anti-Crush Multihead Weigher designed for gentle handling and precise weighing of fragile products. It delivers X(0.5) accuracy at 40-60P/M with vertical partition vibration pan and slide-type feeding hoppers minimizing drop height. Ideal for fresh fruits, ice cubes, thin cookies, peanuts, and delicate snacks requiring damage-free portion control.
Product Overview
The Anti-Crush Multihead Weigher represents specialized combination weighing technology specifically engineered to protect fragile, delicate, and easily damaged products throughout the weighing and discharge process. Unlike standard multihead weighers that prioritize speed over product integrity, this gentle-handling system incorporates multiple design innovations to minimize product breakage, preserve visual appeal, and maintain quality standards for premium fragile products.
The Keypack Intelligent (Kunbupack) anti-crush multihead weigher features a comprehensive fragility-reduction design philosophy implemented across every stage of material handling. The vertical partition vibration pan completely separates material flow paths to prevent product collision and crushing during initial feeding. Slide-type feeding hoppers allow products to glide smoothly into weighing buckets rather than dropping, significantly reducing impact forces that cause breakage in conventional systems.
The inward-tilting weighing buckets pre-shorten the drop height before discharge, while gentle-angle discharge chutes enable products to slide smoothly to the next stage rather than free-falling. This comprehensive approach to minimizing drop height at every transfer point protects product integrity throughout the entire weighing cycle, making this system ideal for fresh fruits, ice cubes, thin cookies, delicate crackers, coated peanuts, and other fragile items that command premium pricing based on visual quality and structural integrity.
Built with high-precision custom sensors and intelligent multi-sampling stabilization modes, the system maintains X(0.5) accuracy class performance while operating at gentle speeds that prioritize product protection. The CAN bus modular architecture with Modbus industrial protocol integration enables seamless communication with packaging equipment for unified control, while intelligent fault alarm systems simplify maintenance and minimize downtime.

Key Features and Machine Characteristics
Comprehensive Fragility Protection Design
Vertical Partition Vibration Pan: Features vertical divider walls on the main vibration pan that completely separate material flow paths, preventing product-to-product collision and crushing during initial feeding stage. This partitioned design is particularly critical for fragile products like thin cookies, delicate crackers, and coated items where even minor contact can cause visible damage that reduces product value and consumer appeal.
Slide-Type Feeding Hoppers: Innovative slide-type feeding hopper design allows products to glide smoothly into weighing buckets along gentle inclined surfaces rather than dropping vertically. This sliding transfer mechanism dramatically reduces impact forces compared to conventional drop-feed systems, preserving product integrity for delicate items like fresh berries, ice cubes, and thin wafer cookies that fracture easily under impact.
Inward-Tilting Weighing Buckets: Specially designed inward-tilting weighing bucket geometry pre-shortens the vertical drop height before discharge by positioning products closer to the discharge point. This innovative bucket angle reduces free-fall distance and impact velocity when products transfer to discharge chutes, minimizing breakage for fragile items throughout the weighing cycle.
Gentle-Angle Discharge Chutes: Carefully engineered discharge chute angles enable products to slide smoothly and gradually to the next processing stage rather than tumbling or free-falling. These gentle-slope chutes maintain product orientation and minimize impact forces, ensuring fragile products arrive at packaging equipment intact and visually appealing for premium presentation.
Comprehensive Drop Height Reduction: The complete system design philosophy focuses on minimizing drop height at every material transfer point throughout the weighing process. From initial feeding through final discharge, products experience minimal vertical drops and gentle transitions, protecting product integrity and maximizing yield of saleable premium-quality packages.
Intelligent Weighing Technology
High-Precision Custom Sensors: Equipped with specially manufactured high-precision, high-standard load cells engineered to deliver consistent X(0.5) accuracy class performance even at the gentler operating speeds required for fragile product handling. These precision sensors ensure accurate weight control while the system operates in fragility-protection mode, maintaining portion control standards without sacrificing product quality.
Intelligent Multi-Sampling Stabilization Mode: Advanced multi-pass sampling algorithm analyzes product flow characteristics and automatically adjusts weighing parameters in real-time to optimize accuracy while maintaining gentle handling speeds. This intelligent stabilization technology ensures consistent weighing performance across varying product densities and fragility levels, adapting to different product types without manual recalibration.
Intelligent Fault Alarm System: Proactive diagnostic monitoring with intelligent fault detection and alarm prompts enables predictive maintenance, minimizes unplanned downtime, and simplifies troubleshooting for maintenance personnel. Clear error messages and diagnostic codes reduce mean time to repair and help operators quickly identify and resolve issues before they impact production quality or throughput.
Advanced Control and Integration
High-Speed Asynchronous Discharge Function: Advanced asynchronous discharge functionality prevents material accumulation and blockage in discharge chutes even when handling delicate products with irregular shapes or sticky coatings. This feature maintains consistent throughput while preserving gentle handling characteristics, ensuring continuous operation without product damage or system jams.
CAN Bus Modular Architecture: New high-integration modular design utilizing CAN (Controller Area Network) bus technology provides faster data transmission between weighing heads, improved system reliability, and simplified troubleshooting. The distributed control architecture reduces wiring complexity and enables real-time communication for synchronized gentle-handling operation across all weighing heads.
Modbus Industrial Protocol Integration: Implements Modbus industrial standard communication protocol to achieve unified interface control between the combination weigher and packaging machine. This seamless integration eliminates the need for separate control panels, streamlining operator training and enabling centralized monitoring of the complete packaging line from a single touchscreen interface.
10.1-Inch Touchscreen Interface: Intuitive touchscreen HMI provides easy access to all weighing parameters, gentle-handling settings, real-time production data, and diagnostic information. Operators can quickly adjust vibration intensity, discharge timing, and other parameters to optimize performance for different fragile product types.
