Title
(EN) FLEXIBLE TAG AGITATOR
(FR) AGITATEUR D'ETIQUETTE SOUPLE
Abstract
(EN)
Flexible tags (22) are secured to parcels (24) moving upon a conveyor belt (20). The flexible tags (22) each contain a transponder circuit (32) in electrical communication with a transponder antenna (30). The transponder circuit (32) contains a unique digital code containing data relating to the parcel (24). A reader circuit (28) located in proximity to the conveyor (20) is in electrical communication with a reader antenna (26). The reader circuit (28) generates a signal in the presence of a flexible tag (22), which is transmitted to the transponder antenna (30) located on the flexible tag (22). The signal energizes the transponder circuit (32) in the flexible tag (22), which sends a unique digital code via the transponder antenna (30) back to the reader antenna (26). The digital code is transmitted from the reader antenna (26) to the reader circuit (28), where the digital code is analyzed to identify the contents of the parcel (24). The flexible tags (22) are agitated by forced air from a fan (12) to orient the flexible tags in non-parallel alignment in relation to the reader antenna (26) as they move along a conveyor (20).
(FR)
La présente invention concerne des étiquettes souples (22) fixées sur des colis (24) se déplaçant sur un tapis convoyeur (20). Chacune de ces étiquettes (22) contient un circuit transpondeur (32) en liaison électrique avec une antenne de transpondeur (30). Le circuit transpondeur (32) contient un code numérique unique représentant des données concernant le colis (24). Un circuit de lecture (28) placé à proximité du convoyeur (20) est en liaison électrique avec une antenne de lecteur (26). Le circuit de lecture (28), en présence d'une étiquette souple (22), produit un signal qui est émis vers l'antenne du transpondeur (30) placée sur l'étiquette (22). Ce signal excite le circuit transpondeur (32) de l'étiquette (22), qui envoie un code numérique unique via l'antenne du transpondeur (30) vers l'antenne du lecteur (26). Le code numérique passe de l'antenne du lecteur (26) au circuit de lecture (28), dans lequel ce code numérique est analysé afin d'identifier le contenu du colis (24). Les étiquettes souples (22), lors de leur déplacement sur le convoyeur (20), sont agitées à l'aide d'air provenant d'un ventilateur (12) de manière à les orienter dans un alignement non parallèle par rapport à l'antenne de lecteur (26).
