Device and method for optically scanning a machine-readable label applied to an object
First Claim
1. A method for scanning a machine-readable label on a retail item selected by a customer in a self-service store, said method comprising:
- providing a first conveyor having an upper surface;
placing a second conveyor over the upper surface of the first conveyor, said second conveyor having a plurality of slats extending across the first conveyor to define pockets therebetween for receiving the retail items;
moving the first and second conveyors at the same speed toward a scanner, with the first conveyor carrying the retail items on its upper surface with it towards the scanner; and
when the retail item is immediately adjacent the scanner, using the slats instead of the first conveyor to carry the retail item across the scanner.

Abstract
A device and a method for the optical scanning of a machine-readable label applied to an object are proposed. The device has at least one belt conveyor (1) and one receiving tray, which are located sequentially spaced apart. A scanning device (3) is located between the belt conveyor (1) and the receiving tray. An additional conveyor device (4) is provided close to the belt conveyor (1) and the scanning device (3) which has several carriers (7) running perpendicular to the direction of travel of the belt conveyor (1). Between two carriers (7) there is a space (12) to accommodate an object. The conveying device (4) covers the scanning device (3) completely and the belt conveyor (1) at least partially. An object is placed on the belt conveyor (1) between two carriers (7) with the side carrying the label and taken across the scanning device (3) by the carriers (7). Then the object is taken to the receiving tray by the carriers (7).

5. A device for use in a self-service store for optically scanning a machine-readable label applied to a retail item, comprising:
-
a first belt conveyor having a first upper surface and being guided by a first pair of pulleys; a second belt conveyor having a second upper surface and being guided by a second pair of pulleys; an optical scanning device positioned between the first belt conveyor and the second belt conveyor; an additional conveyor device disposed around the first and second belt conveyors and the scanning device, comprising; first and second conveyor organs spaced apart from each other so as to lie directly on the first and second upper surfaces of the first and second belt conveyors and run along sides of the first and second belt conveyors; a plurality of carriers attached to the conveyor organs and positioned perpendicular to the direction of conveyance of the first and second belt conveyors so as to lie directly on the first and second upper surfaces of the belt conveyors; the additional conveyor device extending around both belt conveyors such that the conveyor organs encircle the first and second belt conveyors and the scanning device and are guided by one of the first pair of pulleys and one of the second pair of pulleys; and a drive device configured to drive the first and second belt conveyors and the additional conveyor device conveyor device at the same speed; wherein the plurality of carriers and the conveyor organs cooperate to define a corresponding plurality of pockets for receiving the retail item. - View Dependent Claims (6, 7)
