■ FAQ
Q 1. What is a tubes and cans check weigher?
A: A tubes and cans check weigher is an automatic inline weighing machine that verifies the weight of filled tubes, cans, and cylindrical containers during production. It detects underweight, overweight, and missing-content products and automatically removes them from the production line.
Q 2. What types of products can be inspected?
A: The system is suitable for:
- Cosmetic tubes
- Toothpaste tubes
- Pharmaceutical ointment tubes
- Aerosol cans
- Beverage cans
- Food cans
- Chemical containers
- Pet food cans
- Aluminum and plastic containers
Q 3. How accurate is a tubes and cans check weigher?
A: Accuracy depends on product size, weight range, and conveyor speed. High-performance models can achieve accuracy up to ±0.1g to ±0.5g under optimal production conditions.
Q 4. Can the machine handle different tube and can sizes?
A: Yes. Checkweighers support multiple product recipes, allowing operators to switch quickly between different container diameters, heights, and weight specifications.
Q 5. What is the maximum inspection speed?
A: Inspection speed varies by model and application. High-speed systems can inspect hundreds of tubes or cans per minute while maintaining reliable weighing accuracy.
Q 6. How are non-conforming products rejected?
A: The machine can be equipped with different reject devices, including:
- Air blast rejector
- Pusher rejector
- Swing arm rejector
- Drop reject system
- Diverter reject system
The appropriate reject method depends on product characteristics and production speed.
Q 7. Can the check weigher be integrated into an existing production line?
A: Yes. Tubes and cans check weighers are designed for seamless integration with filling machines, cappers, labelers, metal detectors, and packaging equipment.
Q 8. Does the machine store production data?
A: Yes. Most systems provide real-time statistics, production reports, weight trends, reject records, and product recipes for quality control and traceability purposes.
Q 9. Is the equipment suitable for food and pharmaceutical industries?
A: Yes. The machine is typically manufactured from SUS304 or SUS316 stainless steel and can comply with GMP, HACCP, FDA, and other industry requirements.
Q 10. How does a check weigher help reduce production costs?
A: By detecting weight deviations in real time, the system minimizes product giveaway, reduces waste, improves filling accuracy, and helps manufacturers optimize production efficiency.
Q 11. Why choose an automatic tubes and cans check weigher?
A: An automatic tubes and cans check weigher provides 100% weight inspection, improves product quality, ensures regulatory compliance, reduces labor costs, and enhances overall production line performance.
