CHUTE AND VIBRATION TRANSPORT DEVICE

To provide a chute capable of realizing constant feeding of work-pieces under a situation where undulation change of a portion unit of a transport surface caused by an amplitude is prevented/suppressed, staying of a work-piece reaching a transit part to a next process facility on the part and disorder of an attitude is prevented/suppressed, and attitude change of the work-piece at transit to a work-piece transfer surface of the next process facility is prevented/suppressed.SOLUTION: A chute comprises: a transport path 2 having a transport surface 21; and a transport part 3 for transmitting vibration caused by elastic deformation to the transport surface 21. A vibration mode where the transport part 3 is elastically deformed by a drive part 4 is elliptic vibration where a horizontal vibration mode and a vertical vibration mode are synthesized. The whole transport surface 21 is constituted so as to be positioned at a middle part of the horizontal vibration mode to generate a uniform elliptic vibration in the whole transport surface 21.SELECTED DRAWING: Figure 2 【課題】振幅に起因する搬送面の部位単位の起伏変化が生じる事態を防止・抑制するとともに、次工程設備への乗り継ぎ部分に到達しているワークが当該部分で停滞したり、姿勢が乱れる事態の発生を防止・抑制するとともに、次工程設備のワーク移載面への乗継時にワークの姿勢変換を防止・抑制した状況下でワークの定量供給を実現可能なシュートを提供する。【解決手段】搬送面２１を有する搬送路２と、弾性変形によって生じた振動を搬送面２１に伝達する搬送部３とを備え、駆動部４によって搬送部３を弾性変形させた振動モードが水平振動モードと垂直振動モードを合成した楕円振動であり、搬送面２１全体が水平振動モードの腹の部分に位置するように構成して搬送面２１全体に一様な楕円振動が生成されるようにした。【選択図】図２
