COUNTING BAR-SHAPED PRODUCTS BASED UPON ACQUIRED IMAGES

摘要

A conveyor element (2) of a conveyor device conveys bar-shaped products (1) orthogonal to a longitudinal direction (x) of the bar-shaped products (1) oriented in a conveying direction (y). A trigger device (3) provides a trigger signal (S) each time the conveyor element (2) has traveled a predetermined interval. Based upon the respective trigger signal (S), an image (B) is acquired by a camera (4). The image (B) shows front ends of the products (1) in a respective section of the conveyor element (2) corresponding at least to the predetermined interval. Based upon the acquired images (B), the number of bar-shaped products (1) conveyed by the conveyor element (2) is determined.

主权项

1. A method of operation for a conveyor device for conveying bar-shaped products, wherein the bar shaped products have a longitudinal direction;
the method comprising: conveying the bar-shaped products by a conveyor element in a conveying direction orthogonal to the longitudinal direction of the bar-shaped products; providing a respective trigger signal by a trigger device each time the conveyor element has traveled a predetermined interval; acquiring an image by a camera based upon the respective trigger signal, such that the acquired image shows front ends of the products then in a respective section of the conveyor element corresponding at least to the predetermined interval; and determining the number of bar-shaped products conveyed by the conveyor element based upon the acquired images.
