To provide a press brake which can perform positioning of a work-piece in a height direction without visual confirmation near the work-piece to be bent, a bending system and a sensor movement control method.SOLUTION: A press brake comprises: an upper die and a lower die that are relatively movable; a height detection sensor which can detect a height direction position of a work-piece inserted between the upper die and the lower die; a height detection sensor move part which moves the height detection sensor in a longer direction of the upper die and the lower die; and a control part. The control part includes: a movement control part which moves the height detection sensor to the vicinity of a position of work-piece holding means for holding the work-piece; and a height determination processing part which determines whether the height direction position of the work-piece detected by the height detection sensor falls within an allowable range or not.SELECTED DRAWING: Figure 1 【課題】曲げ加工を行うワークの近傍で目視確認することなくワークの高さ方向の位置決めができるプレスブレーキ、曲げ加工システム及びセンサ移動制御方法。【解決手段】相対移動可能な上型及び下型と、前記上型及び前記下型の間に挿入されるワークの高さ方向の位置を検出可能な高さ検出センサと、前記高さ検出センサを前記上型及び下型の長手方向に移動させる高さ検出センサ移動部と、制御部とを備え、前記制御部は、前記ワークを保持するワーク保持手段の位置の近傍に前記高さ検出センサを移動させる移動制御部と、前記高さ検出センサにより検出された前記ワークの高さ方向の前記位置が許容範囲に収まっているか否かを判定する高さ判定処理部とを含む。【選択図】図１
