    • A method and apparatus for counting irregularly-shaped articles. A pair of light sources are provided at a sensing plane through which articles to be counted pass. Each of the light sources emits a light beam that is at an angle to the other light beam, such as an angle of about 90.degree.. Corresponding light sensors are positioned opposite the respective light sources to receive the light signals as the articles pass through the sensing plane. A time division multiplex circuit is provided to alternately operate the light sources, and the outputs from the respective light detectors are summed to provide a unitary signal that is provided to a counter to maintain a count of the number of articles passing through the sensing plane. The system provides combined output signals that are substantially independent of the orientation of the article at the sensing plane.
    • 用于计数不规则形状制品的方法和装置。 在要被计数的物品通过的感测平面处设置一对光源。 每个光源发射与另一光束成一角度的光束,例如约90°的角度。 相应的光传感器与各个光源相对设置,以在物品通过传感平面时接收光信号。 提供时分复用电路以交替地操作光源,并且来自各个光检测器的输出相加以提供提供给计数器的统一信号,以维持通过感测平面的物品数量的计数。 该系统提供组合的输出信号,其基本上独立于物体在感测平面处的取向。

    • A method and apparatus for counting irregularly-shaped articles. A pair of light sources are provided at a sensing plane through which articles to be counted are adapted to pass. Each of the light sources emits a light beam that is at an angle to the other light beam, such as an angle of about 90.degree.. Corresponding solar cells are positioned opposite the respective light sources to receive the light signals as the articles pass through the sensing plane. The light sources are alternately operated and the outputs from the respective light detectors are used to calculate an equivalent volume for the article for comparison with a predetermined article volume range to decide whether to count the article. The method and apparatus permit accurate counts of irregularly shaped articles and are substantially independent of the orientation of the article at the sensing plane.
    • 用于计数不规则形状制品的方法和装置。 一对光源设置在感测平面上,待计数的物品将通过该平面通过。 每个光源发射与另一光束成一角度的光束,例如约90°的角度。 对应的太阳能电池与各个光源相对设置,以在物品通过传感平面时接收光信号。 交替地操作光源,并且使用来自各个光检测器的输出来计算用于与预定物品体积范围进行比较的物品的等效体积以决定是否对物品进行计数。 该方法和设备允许不规则形状制品的精确计数,并且基本上与制品在感测平面处的取向无关。
