  • Tube pusher plate including rotary disk and cylindrical guide rod
    Patent number: 6071067
    Abstract: An apparatus for unloading tubes containing IC devices is disclosed, providing a quiet, low-wear device for separating and ejecting empty tubes from the bottom of a stack. The apparatus consists of a conventional input tube unloading system with novel tube pusher plate, rotary disk, and guide rod elements that reduce wear on both the apparatus and the tubes themselves. The potential risk of damage to the devices in the tubes is also reduced. The apparatus operates quietly because of low friction contact points with the tubes, thus reducing operator fatigue associated with noise.
