A transfer apparatus (10) includes a shuttle (60) depending from an overhead (58) support with a pair of arms (68, 70) for receiving and shifting a specimen carrier (18) from one conveyor (12) to a second conveyor (14) of a dual-conveyor track. The shuttle is operable to retain a specimen carrier along either the first or second conveyor and to release a specimen carrier along either the first or second conveyor. Sensors (40, 42, 48, 50) are located to detect the presence of a specimen carrier at each of the retention locations, and to confirm the release of a specimen carrier from the shuttle along each of the conveyors. A drive motor (78) for moving the shuttle between the retention and release positions is electrically connected to a command module with a processor, for receiving instructions as to the position of the shuttle. The sensors are also connected to the processor to transmit detection data to the processor. A queue is positioned upstream of the shuttle and is electrically connected to the processor. The queue includes retractable shafts, sensors and scanners for selectively retaining, detecting and scanning identification data from a specimen carrier on either conveyor upstream of the shuttle, and transmitting the information to the processor.

Un appareil de transfert (10) comprend une navette (60) dépendant d'un support suspendu (58) ayant une paire de bras (68, 70) permettant de recevoir et de déplacer un support d'échantillons (18) d'un premier transporteur (12) à un second transporteur (14) d'une piste à deux transporteurs. La navette peut fonctionner de manière à retenir un support d'échantillons soit le long du premier transporteur soit le long du second transporteur et de manière à libérer un support d'échantillons soit le long du premier transporteur soit le long du second transporteur. Des capteurs (40, 42, 48, 50) sont disposés de manière à détecter la présence d'un support d'échantillons au niveau de chacun des emplacements de retenue, et à confirmer la libération d'un support d'échantillons à partir de la navette le long de chacun des transporteurs. Un moteur d'entraînement (78) conçu pour déplacer la navette entre la position de retenue et la position de libération est connecté électriquement à un module de commande doté d'un processeur, afin de recevoir les instructions relatives au positionnement de la navette. Les capteurs sont également connectés au processeur pour transmettre des données de détection au processeur.
