A conveyor system having an improved conveyor transfer assembly (10) is provided for transferring articles from the end of a first conveyor to the start of a second, in-line conveyor. The conveying surface of the transfer assembly is formed by rollers (26) driven by a magnetic coupling system (40) which delivers power from an independent power source (44, 46). In addition, magnets (60, 62) are used for providing a positive attachment between the conveyor transfer assembly (10) and the conveyor supports (20) which span between the first and second conveyors. Thus, when an article jam occurs adjacent to the transfer assembly, the positive magnet attachment is overcome and, likewise, the magnetic coupling between the power source (44, 46) and the rollers (26) is also overcome thereby releasing the power connection. This allows the transfer assembly (10) to be bodily lifted and released to prevent damage to the articles. The transfer assembly (10) may also contain a tether (98) connected to the frame to restrain and suspend the transfer assembly following its release.

Cette invention concerne un système transporteur doté d'un ensemble perfectionné de transfert (10), ledit système étant conçu pour transférer des articles de la fin d'un premier transporteur au début d'un second transporteur en ligne. La surface de transport de l'ensemble de transfert est formée par des rouleaux (26) entraînés par un système de couplage magnétique (40) qui assure l'alimentation en énergie à partir d'une source d'énergie indépendante (44, 46). En outre, des aimants (60, 62) servent à fournir une fixation positive entre l'ensemble de transfert (10) du transporteur et les supports du transporteur (20) qui s'étendent du premier au second transporteurs. Ainsi, lorsqu'un encombrement d'articles se produit à proximité de l'ensemble de transfert, la fixation positive assurée par les aimants cède, de même que le couplage magnétique entre la source de puissance (44, 46) et les rouleaux (26), ce qui supprime la connexion électrique. Ceci permet à l'ensemble de transfert (10) d'être soulevé fermement et libéré pour éviter des dégâts aux articles. L'ensemble de transfert (10) peut également contenir un câble d'attache (98) relié au bâti de façon à retenir et suspendre l'ensemble de transfert après sa libération.
