Keypack Intelligent 16 Head Multihead Weigher 3 Layer designed for quantitative weighing of granular, flake, irregular-shaped, and puffed materials across food, confectionery, frozen food, and small hardware packaging lines. With a weighing range of 10–1000 g, X(0.5) accuracy class, and a maximum speed of 100×2P/M, the system integrates a three-layer memory hopper configuration and CAN bus control to support stable, high-throughput combination weighing.
Product Overview
The 3-Layer 16-Head Weigher represents advanced combination weighing technology engineered for high-precision dosing of diverse free-flowing materials including granular, flake, strip, round, irregular-shaped, and puffed products. This intelligent weighing system features a unique three-layer configuration with memory hoppers that temporarily store weighed materials, significantly increasing combination probability and enhancing overall weighing accuracy beyond standard two-layer systems.
The Keypack Intelligent (Kunbupack) multihead weigher integrates high-precision custom sensors with intelligent multi-sampling stabilization modes to ensure consistent, accurate weighing performance across diverse product types and densities. Built with a fully enclosed chassis and integrated center seat welded construction, this combination scale delivers superior structural rigidity and reduced hopper stabilization time for faster weighing cycles and higher production throughput.
The separated main vibration pan design accommodates two different mixed materials simultaneously, while independent main vibrators control feeding thickness for each material type separately. Advanced asynchronous high-speed discharge functionality effectively prevents material blockage, ensuring continuous operation in demanding production environments. The 10.1-inch touchscreen interface with Modbus industrial communication protocol enables seamless integration with packaging machines for unified control.

Key Features and Machine Characteristics
Intelligent Weighing Technology
High-Precision Custom Sensors: Equipped with specially manufactured high-precision, high-standard load cells that deliver consistent X(0.5) accuracy class performance across varying product densities and environmental conditions, ensuring reliable weight measurements for quality control and regulatory compliance in food and industrial applications.
Multi-Sampling Stabilization Mode: Intelligent multi-pass sampling algorithm analyzes product flow characteristics and automatically adjusts weighing parameters in real-time, resulting in superior accuracy and reduced giveaway. This advanced stabilization technology directly improves profit margins on high-volume production runs by minimizing product waste.
Three-Layer Memory Hopper Innovation: The unique three-layer configuration with dedicated memory hoppers temporarily stores pre-weighed batches before final discharge, dramatically increasing the number of possible weight combinations. This advanced design enhances weighing precision and consistency compared to standard two-layer systems, particularly beneficial for difficult-to-weigh products with irregular shapes or varying densities.
Advanced Control and Integration
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 operation.
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, reducing production floor footprint, and enabling centralized monitoring of the complete packaging line.
10.1-Inch Touchscreen Interface: Intuitive touchscreen HMI provides easy access to all weighing parameters, real-time production data, and diagnostic information. Operators can quickly adjust settings, monitor performance metrics, and access historical data for quality assurance and process optimization.
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 (MTTR).
Mechanical Excellence
Dual-Material Capability: Features separated main vibration pan design that accommodates two different material types simultaneously, enabling mixed-product weighing for combination packs, trail mixes, or multi-component recipes without changeover time. This flexibility maximizes production efficiency for manufacturers offering diverse product portfolios.
Independent Vibrator Control: Dedicated independent main vibrators for each material stream allow precise control of feeding thickness and flow rate for different product characteristics. This optimization capability ensures consistent performance for products with varying bulk densities, fragility levels, or flow properties.
Diamond-Shaped Hopper Design: Specially engineered diamond-shaped hoppers concentrate materials toward the center discharge point, accelerating material flow and reducing discharge time. This geometric optimization contributes to faster weighing cycles and higher overall throughput.
High-Speed Asynchronous Discharge: Advanced asynchronous discharge functionality prevents material accumulation and blockage in discharge chutes, maintaining consistent throughput even with sticky, fragile, or irregularly shaped products that typically challenge conventional systems. This feature is particularly valuable for products like dried fruits, candies, and delicate snacks.
Reinforced Structural Design: Fully enclosed chassis with integrated center seat one-piece welding construction significantly enhances machine rigidity and stability. This robust design reduces hopper stabilization time, enabling faster weighing cycles, minimizing vibration transmission, and improving long-term dimensional accuracy.
Step Motor Drive System: Precision step motor drive provides accurate, repeatable hopper door operation with minimal maintenance requirements. The step motor system ensures consistent discharge timing and contributes to overall weighing accuracy.
