ABSTRACT:
Automatic sorting machine for sorting and classifying small products of the pharmaceutical and confectionery industries according to form and color. The present invention pertains to an automatic sorting machine for sorting and classifying these products for deviations, via optoelectronic specimen recognition, with the machine including a vibratory inlet device in which the products to be sorted are separated in order to present same to a delivery device for conveying the separated products through a beam/light path of a camera. Each product is optically comprehended by the camera and encoded into electrical signals, via which specimen recognition is carried out through appropriate electronics in order to eliminate unrecognized products having improper deviations. In order to classify the product with substantially higher processing speeds and in order to achieve a defined color report, a color-line camera is provided, which pans the beam/light path of the camera in the feeding direction of the product over a determined conveying track, and the product, during its throughput through the panned beam/light path, is rotated about an axis parallel with the scanning line.
