WRAPPED-PRODUCT QUALITY CONTROL AND PACKING METHODS, AND WRAPPED-PRODUCT QUALITY CONTROL AND PACKING DEVICES

摘要

A wrapped-product quality control method and a wrapped-product packing method comprise providing a wrapped product comprising a product in a wrapper; supplying the wrapped product on a measuring background in a capture range of an infrared-sensitive imaging device, the product having a product temperature different from a measuring background temperature of the measuring background,and the wrapper having a wrapper temperature; capturing with the infrared-sensitive imaging device infrared radiation from the wrapped product and the measuring background; providing an image of the product or of the wrapped product from said infrared radiation captured with said infrared-sensitive imaging device; and analysing said image for quality control of said wrapped product. A wrapped-product quality control device and a wrapped-product packing device comprise an infrared-sensitive imaging device configured and arranged for capturing infrared radiation from a wrapped product on a measuring background, the product having a product temperature different from a measuring background temperature of the measuring background, and the wrapper having a wrapper temperature; and a computer for providing an image of the product or of the wrapped product from the infrared radiation captured with the infrared-sensitive imaging device, and for analysing the image for quality control of the wrapped product.
