How to Achieve Accurate Counting for Pre-Packaged Items
Candies, puffed snacks, coffee sticks, marinated eggs, chicken feet, konjac snacks, and other pre-packaged food and pharmaceutical products bring protection and convenience, but they also make accurate counting and secondary packaging on production lines challenging.
What: What is Vision Counting for Pre-Packaged Items?
VisCount automatic vision counting machines use industrial cameras and algorithms to identify and count each individual package, ensuring high-precision batch packaging. This method does not rely on weight or volume but directly “sees” each item, avoiding errors caused by traditional weighing methods.
Why: Why is Counting Pre-Packaged Items Challenging?
- Light-weight individual packages lead to large weighing errors
- Soft or flexible packaging easily stacks or overlaps
- Photoelectric sensors struggle to distinguish closely packed small bags
- Reflective packaging or printed designs may interfere with detection
How: Workflow of Vision Counting and Packaging
1. Counting
- Set the desired quantity per bag
- Material is dispersed evenly using a vibration feeder
- Multi-channel counting ensures uniform drop of small packages
- Excess items are automatically removed and recirculated
2. Conveying and Bagging
- The complete batch is conveyed to the packaging station
- Small packages can be aligned or slightly pressed if needed
- Packaging machine completes sealing and printing
3. Inspection
- Manual or sampling checks for package completeness
- Verify small package quantity
- Check sealing quality
Application: Suitable Materials for Vision Counting
| Industry | Example Materials |
|---|---|
| Food | Small bag candies, puffed snacks, coffee sticks, marinated eggs |
| Pharmaceuticals | Blister-pack medication tablets |
| Agriculture | Small seed packets |
Why: Can Different Package Sizes be Compatible?
Standard machines can handle multiple package sizes, and special items can be adapted with partial upgrades without replacing the entire machine.
How: How to Ensure Efficiency with Large Items?
- Adjust parameters during trial tests
- Increase channel numbers to boost counting speed
FAQ: Common Questions
Can different package sizes use the same machine?
Most standard models cover a wide range, and multiple sizes can be accommodated with partial upgrades.
Will large items reduce counting efficiency?
Increasing channel numbers can improve overall throughput and maintain production speed.
Are vision counting machines suitable for food and pharmaceuticals?
Yes, when complying with CE, ISO, and other relevant standards, vision counting machines are applicable for pre-packaged food and pharmaceutical products.
Why: Why Vision Counting is the Best Solution
Vision counting can identify each individual package, eliminating errors caused by weight differences, shape irregularities, and stacking. Combined with multi-channel design, automatic removal, and system integration, it provides high-precision, traceable counting and packaging, becoming the mainstream solution for pre-packaged items.
