Automated Counting Multihead Weigher and Bagging Line for Secondary Packaging

A) Multihead Weigher with Counting Function (Counting-by-Weight)

Key benefits

• High accuracy piece count with counting-by-weight + verification logic

• Fast output because multiple hoppers weigh in parallel and the algorithm selects the best combination instantly

• Lower giveaway vs systems prone to +/- piece errors, especially when piece weight varies

How it works (factory-friendly explanation)

1. Reference calibration: calculate average single-piece weight (baseline)

2. Parallel weighing + combination algorithm: choose hopper combination that matches the target count

3. Dual verification: count check + total weight check before discharge

4. Adaptive self-learning: auto-adjusts to small weight drift during long runs

B) VFFS (Vertical Form Fill Seal) Packing Machine

• Bag forming + filling + sealing into pillow or gusset master bags

• Built to run with counted discharge from the weigher for stable secondary packaging output

Q1: What this line does? 
A1: This is a complete secondary packaging solution: it takes individual small packs (like jelly cups / triangle jelly bags / mini wrapped snacks), counts the exact quantity using a multihead weigher with counting function, then forms–fills–seals them into a larger master bag for bulk sales or distribution.

Q2: Why is “counting-by-weight” better than a traditional optical counter?
A2: Traditional counters rely on products passing a sensor one-by-one in a single file. This often leads to miscounts when products bounce, overlap, or stick together. Our counting-by-weight method weighs multiple items at once and uses an algorithm to achieve the target count, making it faster and far more accurate for products that are not perfectly uniform.

Q3: What happens if the weight of my individual items varies slightly?
A3: The system is designed for this. The weigher’s software includes a self-learning function that continuously calculates the average single-piece weight during the production run. This allows it to adapt to small drifts in weight, ensuring the final piece count in each bag remains accurate over time.

Q4: Is this a complete, all-in-one solution?
A4: Yes, we provide a complete, turnkey line. Beyond the core counting weigher and VFFS machine, we design and integrate the entire workflow. This includes the infeed system to properly feed your products, and any downstream equipment you need, such as checkweighers, metal detectors, and robotic case packers.
