Abstract
A conveyor system having an improved conveyor transfer assembly 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 driven by a magnetic coupling system which delivers power from an independent power source. In addition, magnets are used for providing a positive attachment between the conveyor transfer assembly and the conveyor supports 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 and the rollers is also overcome thereby releasing the power connection. This allows the transfer assembly to be bodily lifted and released to prevent damage to the articles. The transfer assembly may also contain a tether connected to the frame to restrain and suspend the transfer assembly following its release.
