Method and apparatus for putting articles into a queue
First Claim
1. Apparatus for putting articles into a queue, the comprising a plurality of parallel transfer conveyors which are suitable, together or separately, for transferring an article from the outlet of an inlet conveyor to the inlet of an outlet conveyor, between which and in line with which the transfer conveyors extend, and which includes a camera for observing articles on the inlet conveyor and means for deriving article outline and identity data from images taken by the camera, and means for selectively actuating the transfer conveyors as a function of said outline and identity data.

Abstract
The present invention relates to a method of putting articles into a queue and apparatus enabling he method to be implemented. According to the invention, apparatus for putting articles into a queue comprises a plurality of parallel transfer conveyors which are suitable, together or separately, for transferring an article from the outlet of an inlet conveyor to the inlet of an outlet conveyor, between which and in line with which the transfer conveyors extend, and which includes a camera for observing articles on the inlet conveyor and means for deriving article outline and identity data from images taken by the camera, and means for selectively actuating the transfer conveyors as a function of said outline and identity data.

- 2. Apparatus for transporting and separating articles, the apparatus comprising a multibelt conveyor having a plurality of belts extending parallel and side by side, each forming a transfer conveyor, each belt being suitable for being driven individually under the control of an electronic control unit as a function of data that results from identifying the outline of an individualized article, which outline is obtained by processing one or more images taken by a camera for observing the articles presented broadside-on at the inlet of the multibelt conveyor, an individualized article selected from a plurality of articles being selectively transferred by actuating the belts that are in line with said individualized article differently from the belts which do not lie in line with said individualized article.
-
11. A method of separating a group of articles in bulk that are presented broadside-on on an inlet conveyor, the method comprising:
-
taking an image of the group of articles;
determining the number of articles in the group and the outline of each article by computation on the basis of the image, thereby making it possible to determine the position and the width of the base of each of the articles in a transverse vertical plane; and
controlling the belts or parallel groups of belts of a multibelt conveyor that extends said inlet conveyor to advance in non-uniform manner (at different speeds and/or at different times) so as to correspond to each of the individualized articles respectively, in such a manner that the articles in the group of articles are presented at the outlet from the multibelt conveyor with longitudinal offsets between articles forming successive pairs of articles. - View Dependent Claims (12, 13)
