(2-1)物品供給ユニット
物品供給ユニット90は、分散部10に物品を供給するユニットである。物品供給ユニット90は、図1に示すように、分散部10の上方に配置されている。物品供給ユニット90は、物品供給ユニット駆動部90aによって駆動される(図3参照)。
分散部10は、上述した物品供給ユニット90から搬送された物品を受けて、当該物品を放射部20へ搬送するユニットである。具体的に、分散部10は、物品供給ユニット90から搬送された物品を振動により分散させて各放射部20a~20nに送る。
放射部20は、分散部10から物品を受け取り、当該物品をプールホッパ30に供給する。放射部20は、分散部10によって供給された物品を受け取り、さらに下流に配置されたプールホッパ30へ物品を供給する。
