Definitions

  • the features according to claim 4 are preferably also embodied.
  • Thin carrier elements are easy to eliminate from obtained images when the position thereof is well known beforehand. This is particularly the case when the features of claim 5 are also implemented, wherein synchronization of the movement of such a carrier and obtaining of an image is practically irrelevant because the thin carrier elements also extend in the direction of movement of the carriers. If they were to extend in a direction transversely thereof, the considerations in respect of synchronization would then be of greater importance in properly determining the position of particularly these carrier elements beforehand so as to enable elimination thereof, or measures would have to be taken to identify these carrier elements in an obtained image, which requires computing capacity and can result in delay.
  • the apparatus can further have the features of claim 9.
  • the apparatus according to the invention can further have the features according to claim 10, so that at a selected destination the products for sorting can simply be tipped out. In an apparatus according to the invention it is also recommended that it has the features of claim 11.
  • the products 4 for sorting are for instance asparagus.
  • Fig. 2 shows a top view which is obtained using upper camera 7 in fig. 1.
  • Fig. 3 shows a bottom view obtained using lower camera 8 in fig. 1.
  • Carriers 6 each consist of a tiltable crossbar 9 on which are arranged brackets 10 forming thin wire elements. Further arranged on crossbars 9 are hook arms 11, which can be engaged by an engaging member (not shown) in order to tilt crossbars 9 and cause the products for sorting 4 to fall off carriers 6 at a desired location. These locations are the destinations 12, 13 and 14 in fig. 1.
  • a control (not shown) with imaging means therein processes the images obtained with cameras 7, 8.
  • brackets 10 extend exactly in the direction of forward movement of arrow A of carriers 6, such a synchronization is less important, as long as an image is obtained of the product for sorting 4 in each of the carriers 6.
  • Carrier 15 substantially comprises a transparent holder 16 into which a product for sorting can be placed.

Abstract

La présente invention concerne un dispositif (1) pour réaliser un tri optique de produits (4), en particulier de produits agricoles, en fonction des propriétés physiques des produits telles que la longueur et la couleur. Le dispositif (1) comprend: un système de transport comprenant un côté alimentation (2) et un côté déchargement (3); des éléments de support (6) disposés dans le système de transport et destinés à transporter chacun des produits (4) vers l'une d'au moins deux destinations sur le côté de déchargement (3) ou à proximité de celui-ci; un système d'imagerie pour fournir une image de chacun des produits; et un système de commande avec système de traitement d'image, pour déterminer les propriétés physiques de chaque produit et actionner les éléments de support pour qu'ils transportent chaque produit vers la destination pertinente parmi les destinations, en fonction des propriétés physiques détectées. Le système d'imagerie comprend au moins deux caméras (7, 8) qui sont disposées des deux côtés de la trajectoire et sont orientées vers les supports (6) en pouvant se déplacer entre eux pour obtenir des images complémentaires de chaque produit.
