偵測具有不規則載入的棧板
應用挑戰
在包裝應用中，通常棧板將載入各種形狀和顏色的盒子。這會為傳統光電裝置帶來感測挑戰，這些裝置可能會因為顏色、反射率和表面不一致而發生誤判。需要一種解決方案，無論盒子形狀或顏色如何，當輸送帶通過時，都可以可靠地檢測棧板。
解決方案
超音波感測器將提供可靠的棧板偵測。超音波感測器發出音波，並「偵聽」從目標物反彈回的音波。可以教導感測器可靠的背景，在本例下是輸送帶，並且將偵聽取從輸送機返回的聲波。進入感測器與輸送帶之間的任何物件都將被檢測到，導致輸出切換。
在本應用中，使用的是U-GAGE QT50U超音波感測器。QT50U的擴展範圍高達8米，超音波死區只有總感測範圍的2.5％，並且使用按鈕或遠端TEACH模式編程來簡化設定。
