DEVICE AND METHOD FOR CONTACTLESS DETECTION OF CHARACTERISTICS OF CONTINUOUSLY DELIVERED TRANSLUCENT PRODUCTS
First Claim
1. An apparatus for contactless detection of characteristics of continuously conveyed, translucent products, comprising:
- first and second transmitting units each having an independent light source to generate high-intensity light radiation to illuminate the product, a light-converting element to form a planar light field from the light radiation and a focusing element to form a line of light running transversely to a direction of conveying of the products from the planar light field;
a receiving unit having a detection device to pick up the light radiation transflected by the product; and
shading elements arranged respectively between the transmitting units and the receiving unit;
wherein the first transmitting unit is arranged in front of the receiving unit in the direction of conveying of the products and the second transmitting unit is arranged behind the receiving unit in the direction of conveying.

Abstract
An apparatus for contactless detection of characteristics of continuously conveyed, translucent products includes first and second transmitting units each having an independent light source to generate high-intensity light radiation to illuminate the product, a light-converting element to form a planar light field from the light radiation and a focusing element to form a line of light running transversely to a direction of conveying of the products from the planar light field. A receiving unit has a detection device to pick up the light radiation transflected by the product. Shading elements are arranged respectively between the transmitting units and the receiving unit. The first transmitting unit is arranged in front of the receiving unit in the direction of conveying of the products and the second transmitting unit is arranged behind the receiving unit in the direction of conveying.

16. A method for contactless detection of characteristics of continuously conveyed, translucent products, comprising the steps of:
-
continuously conveying the products through an inspection region of a detection device of a receiving unit; exposing the products to high intensity light radiation from separate light sources both on entering the inspection region and on leaving the inspection region of the detection device; and picking up the light radiation transflected by the products by the receiving unit. - View Dependent Claims (17, 18, 19)
