The Starweigh Checkweigher maintains high throughput and accuracy while handling a wide range of container sizes. Unit can be changed over to handle containers from 30 cc to 2000 cc and it achieves an accuracy of +/- 3 mg at 3 sigma and line speeds up to 200 or 400 cpm. The Starweigh is ideal for hard-to-handle packages including round, oval, rectangular and square containers made of plastic, metal and glass from 0.75 to 6.5 inches in diameter as well as odd-shaped products. Product is fed from a conveyor into pockets in the starwheel. Multiple packages are accumulated into each pocket, which features as many as six sub-pockets, each aligned to a separate scale so each package is isolated as it is weighed. The Starweigh is equipped with multiple weigh pans to achieve the highest accuracy for a wide range of product sizes and weights and features an auto-correct function that re-calibrates and re-zeros each scale with every revolution of the starwheel. This feature corrects for any product build-up and any long-term drift of the weigh cells and electronics.
