Built with robust materials and cutting-edge technology, NK Industries' checkweighers are the ideal solution for pharmaceutical, food and beverage, cosmetic, and chemical industries.
Working Principle of bottle checkweigher machine ?
The NK Industries Bottle Checkweigher Machine operates on a dynamic weighing principle. Here's a step-by-step breakdown:
- Infeed Section: Bottles are fed onto the checkweigher's conveyor belt, often with a spacing mechanism to ensure individual weighing.
- Weighing Section: As each bottle passes over the integrated high-precision load cell, its weight is accurately measured in real-time. This happens dynamically, without stopping the production line.
- Control & Display Unit: The measured weight is instantly processed by the machine's controller. This value is compared against pre-set target weight parameters (acceptable upper and lower limits). The HMI (Human Machine Interface), typically a touchscreen display, shows the current weight, operational status, and statistical data.
- Rejection System (Optional ): If a bottle's weight falls outside the defined tolerance (either underweight or overweight), a rejection mechanism is activated. Common rejection systems include:
- Air Jet Rejector: Uses a puff of air to blow the non-compliant bottle off the line.
- Pusher Rejector: Employs a pneumatic or mechanical arm to gently push the bottle onto a separate rejection lane or bin.
- Diverter Arm: A gate or arm diverts the bottle.
- Outfeed Section: Bottles that meet the weight criteria pass through to the next stage of the production line. Rejected bottles are collected separately for inspection or disposal.
Sailent Feature
- High Accuracy & Precision: Employs advanced load cell technology for reliable and repeatable weight measurements.
- Dynamic Weighing: Capable of weighing bottles accurately while in motion, ensuring high throughput.
- User-Friendly HMI: Intuitive touchscreen interface for easy setup, operation, parameter adjustment, and real-time monitoring.
- Robust Construction: Typically built with Stainless Steel (SS304 or SS316 as per industry requirements) for durability and hygiene, especially in food and pharmaceutical applications.
- Variable Speed Control: Conveyor speed can be adjusted to match the production line's pace.
- Multiple Product Profiles: Ability to store settings for various bottle sizes and weights, allowing for quick changeovers.
- Automatic Rejection System: Efficiently removes out-of-specification products without manual intervention.
- Data Logging & Reporting: Capable of storing production data, including weight statistics, which can be used for quality control analysis and compliance documentation. (May include USB or Ethernet connectivity for data transfer).
- Easy Integration: Designed for seamless incorporation into existing bottling and packaging lines.
- Low Maintenance: Engineered for reliability with easily accessible components for routine cleaning and maintenance.
- Compliance: Helps meet regulatory requirements such as GMP (Good Manufacturing Practices) and other industry-specific standards.
