Volumetric-Measuring Cup Filling Machine

Keypack Intelligent Volumetric Cup Filling VFFS Machine is a servo-driven Vertical Form-Fill-Seal Machine engineered for accurate metering and continuous packaging of granular and mixed granule–powder materials. It delivers 5–100 bags/min across six model configurations (KL-320 to KL-1250), powered by a PLC servo control system with pneumatic actuation and a large touchscreen interface. Ideal for food, agricultural, nutraceutical, and chemical packaging lines requiring a reliable Volumetric Cup Filling Machine, Vertical Packaging Machine, or VFFS Machine.

Product Overview

The Keypack Intelligent Volumetric Cup Filling Vertical Form-Fill-Seal Machine is available in six models — KL-320, KL-420, KL-520, KL-620, KL-820, and KL-1250 — covering a bag-making size range from (L)60mm up to (L)800mm and a speed range from 5 to 100 bags/min, making it suitable for small-batch specialty packaging through to high-throughput production lines.

At its core, this Vertical Packaging Machine integrates a PLC servo drive system, a pneumatic control system, and an oversized touchscreen HMI as the primary control architecture. This combination delivers high control precision, operational reliability, and intelligent automation across the full packaging cycle — from volumetric cup metering and bag forming, through sealing, date printing, inflation or deflation, finished-product conveying, and automatic counting.

The Keypack Intelligent (kunbupack) Volumetric Cup Filling Packaging Machine supports single-belt or double-belt film-pulling systems for fast, stable, low-friction film transportation. The touchscreen stores packaging parameters for multiple product types, enabling rapid changeover without reconfiguration. An integrated fault display system assists operators in timely troubleshooting, reducing unplanned downtime on the production floor.

When paired with compatible volumetric cup metering systems and conveying systems selected according to product characteristics, this Food Packaging Machine automatically completes the entire packaging process: metering → feeding → filling → bag-making → sealing → inflation/deflation → date printing → counting → finished-product conveying.

Key Features and Machine Characteristics

• PLC Servo Drive Control: The integrated PLC servo drive system, pneumatic control system, and large touchscreen HMI form the core control architecture, delivering high precision, operational reliability, and intelligent automation across the full VFFS packaging cycle.
• Intelligent Temperature Control: An intelligent temperature controller maintains precise sealing temperature, producing neat, smooth, and consistent seals — reducing seal defects and material waste on the packaging line.
• Full-Cycle Automation: When matched with compatible volumetric cup metering and conveying configurations, the machine automatically completes metering, feeding, filling, bag-making, sealing, inflation or deflation, date printing, counting, and finished-product conveying in a single continuous process.
• Multi-Product Touchscreen Storage: The touchscreen HMI stores packaging parameters for multiple product types. Operators can switch products quickly without reconfiguring settings, improving changeover efficiency on multi-SKU production lines.
• Integrated Fault Display System: A built-in fault display system identifies machine issues in real time, helping operators locate and resolve faults promptly to minimize production interruptions.
• Safety Protection Systems: Equipped with complete safety protection mechanisms designed to comply with enterprise safety management requirements for automatic packaging equipment.
• Flexible Bag Format Support: Supports pillow-type bags and hanging-hole bags, accommodating different retail and logistics packaging format requirements.
• Stable Film Transportation: Single-belt or double-belt film-pulling systems provide fast, stable, low-friction, and low-wear film transportation, supporting long-term operational stability of the Vertical Form-Fill-Seal Machine.

Application Areas

• Snack & Confectionery: Volumetric cup filling for candies, roasted nuts, dried fruits, peanuts, pistachios, and mixed nut snacks — granular materials with consistent bulk density.
• Staple & Condiment Food: Granulated sugar, oatmeal, pepper grains, and condiment blends — granule-powder mixed materials requiring stable metering accuracy.
• Beverage & Hot Drink: Coffee beans, loose-leaf tea, and powdered drink mixes — materials sensitive to seal integrity and gas-flushing requirements.
• Pet Food: Dry kibble, treat pieces, and seed-based pet food — granular materials requiring hygienic contact surfaces and reliable bag sealing.
• Agricultural Seeds & Grains: Seeds, grains, and agricultural granular materials — packaged in pillow bags or hanging-hole bags for retail or bulk distribution.
• Chemical & Daily-Use Products: Granular detergent, granular chemical products, and similar non-food granular materials compatible with the machine's material contact specifications.
• Nutraceutical & Health Products: Granular supplement blends and powdered health products requiring date printing, counting, and inflation/deflation functions.
