    • A differential impulse conveyor 10, 80, 90, 100 includes a tray 12 which is driven in a forward direction at a slow speed and a backward direction at a higher speed to slide goods with respect to the tray and thereby move goods along the tray. The drive motor 26, 27 powers the tray in the forward and backward directions through a drive shaft 40 and a tray crank 66, 106 interconnecting the drive shaft and the tray. Controller 84 is provided for varying the rotational speed of the motor shaft, thereby avoiding mechanical knock in the drive system. In another embodiment, a pair of counterweights 52, 62 are provided on opposing sides of the drive shaft 40, with respective counterweight cranks 46, 56 initiating forward movement of each counterweight at a preselected offset angular position with respect to forward movement of the tray. The differential impulse conveyor of the present invention substantially eliminates mechanical knocking in the drive system, thereby extending the useful life of the conveyor and minimizing the size of the conveyor components.
    • 差动脉冲输送机10,80,90,100包括托盘12,该托盘12以较慢的速度在向前的方向上以较高的速度向后方向驱动,以相对于托盘滑动货物,从而沿托盘移动货物。 驱动马达26,27通过驱动轴40和互连驱动轴和托盘的托盘曲柄66,106沿前后方向向托盘供电。 控制器84用于改变电动机轴的转速,从而避免驱动系统中的机械敲击。 在另一个实施例中,一对配重52,62设置在驱动轴40的相对侧上,相应的配重曲柄46,56相对于托盘的向前运动在每个配重的预选偏移角位置处启动向前运动。 本发明的差动脉冲输送机基本上消除了驱动系统中的机械敲击,从而延长了输送机的使用寿命并使输送机部件的尺寸最小化。
