12-Head Gravity Liquid Filling Machine

12-Head Gravity Liquid Filling Machine

Product Overview: 

     This machine utilizes gravity-fed filling with PLC control and photoelectric positioning to deliver accurate filling of 100–1000 ml across diverse container shapes. The compact inline, grouped infeed/outfeed design accommodates drip-shaped, round, and irregular bottles. All-SS 304/316L construction ensures sanitary operation—no drips, no bubbles, no contamination. Ideal for food & beverage (spirits, soy sauce, vinegar, bottled water), pharmaceutical oral liquids, chemical cleaners, and agrochemicals. Fast changeover completes recipe switch in minutes.

Key Features：

● Gravity-Fed Filling：

Utilizes gravity for continuous fill—no pumping required, reducing foam and splatter.

● PLC & Photoelectric Positioning：

PLC manages fill timing; photoelectric sensors detect bottle necks to ensure precise alignment.

● All-SS Sanitary Construction：

Frame, hopper, filling pathways, and nozzles are 304/316L SS, meeting food and pharmaceutical sanitary standards.

● Wide Container Compatibility：

Handles 40–110 mm diameter round, drip-shaped, and irregular bottles, with changeover in minutes.

● High Throughput：

Twelve heads fill in parallel, delivering 30–70 bottles/min (depending on bottle height and liquid viscosity).

● Precise Dosing：

Valve timing and opening are precisely controlled to maintain ±1.5% fill accuracy, minimizing waste.

● Quick Changeover：

Tool-less changeover via guide rail and guard adjustments; recipe switch completed within 5 minutes.

Optional Modules:

Bucket Elevator：Continuously elevates bulk liquids or granules to the hopper for uninterrupted feeding.

Vibratory Feeder：Precisely controls feed rhythm and flow rate for stable multicavity feed.

Conveyor：SS chain or roller conveyor transports filled bottles to labeling or packing stations.

In-Line Labeling Machine：Offers wrap-around, front/back, or shrink-sleeve labeling options, supporting high-speed operation.

Inkjet Coder：Prints batch codes, production dates, barcodes or QR codes in real time for traceability.

CIP Cleaning System：Integrated CIP piping for automated in-place cleaning and sanitizing, reducing downtime.

Custom Bottle Holders:Custom holders designed for irregular bottles to ensure perfect nozzle-to-neck alignment.

Technical Specifications：

Working Principle & Operation:

• Container Loading：

Operators or the unscrambler place empty containers on the infeed conveyor. A photoelectric sensor detects bottle presence, triggering the PLC to start the fill cycle.

• Auto Tare & Calibration：

The PLC automatically performs tare (zero) on the optional weighing platform and loads the fill recipe (fill volume, flow rate, head count).

• Gravity-Fed Filling：

The pneumatic valve opens to a constant position; liquid flows by gravity into the container.

Nozzles are positioned at the bottle mouth with anti-drip design to prevent air ingestion and dripping.

• No-Bottle, No-Fill Safety：

If no bottle is detected or the bottle count mismatches the set fill count, the PLC inhibits filling, ensuring safety and preventing spills.

• Automatic Bottle Discharge：

Filled bottles exit via the outfeed conveyor to downstream stations—labeler, coder, or collection system.

• Real-Time Monitoring & Alarms：

The HMI displays real-time fill speed, counts, and alarms (e.g., fill imbalance, no-bottle, air pressure faults). The PLC halts the line and triggers alarms if any parameter deviates.

Quality & Certification：

Certifications：CE、UL、ISO 9001

QC Process：

• Incoming Inspection – Material and functionality tests on 304/316L stainless steel, pneumatic valves, and photoelectric sensors.
• In-Process Inspection – Real-time monitoring during assembly, verifying nozzle flow rates and positioning accuracy.
• Full-Load Trial Run – 12-head parallel fill, 8-hour continuous run to confirm zero misses and no faults.
• Final Factory Inspection – Sample fills with calibration to ensure ≤±1.5% deviation, issuing acceptance report.
  
  

Frequently Asked Questions (FAQ):

Q: How do I adjust fill volume and speed?

A: On the touchscreen“Fill Settings”screen, enter desired volume (100–1000 ml) and speed (bottles/min). The PLC then controls valve timing for precise dosing.

Q: How does gravity filling prevent air bubbles?

A: Gravity fill with engineered flow channels gently fills bottles from the bottom, avoiding turbulence and air bubble formation.

Q: How to accommodate different bottle shapes?

A: Change or adjust the bottle holders and guards to match the container neck—no other parts need to be swapped.

Q: What is the cleaning process for the filling heads?

A: Detachable nozzles and flow channels support CIP in-place rinsing or manual high-pressure wash after disassembly to meet sanitary standards.

Q: How is ±1.5% fill accuracy maintained?

A: PLC precisely times valve opening; photoelectric sensors verify bottle alignment. If deviation is detected, the system auto-calibrates the next fill.
