description | To enhance the efficiency of processing a press brake 10 under the condition that a press brake 10 is equipped with an optical type safety device 42 to secure a sufficient safety of the work of bend processing.SOLUTION: A judgment part 70 judges, on the basis of the optical receiving state of a photodiode 56located in a moat vicinity of an upper die 12, whether or not a shadow of the upper die 12 with a laser beam B projected on the side of an optical receiver 52 expands to the photodiode 56. A nullification part 72 nullifies the photodiode 56when the shadows of the upper die 12 expands to the photodiode 56located in the most vicinity of the upper die 12. A detection part 74 detects, during a descending motion of an upper table 26, whether foreign matters are present between the upper die 12 and a lower die 14 on the basis of the optical receiving state of a plurality of effective photodiodes 56.SELECTED DRAWING: Figure 1
【課題】プレスブレーキ10が光学式安全装置42を装備して、曲げ加工の作業の安全性を十分に確保した上で、プレスブレーキ10の加工効率を高めること。【解決手段】判定部70は、上金型12の最近傍に位置するフォトダイオード564の受光状態に基づいて、受光器52側に投影されるレーザ光Bよる上金型12の影が、そのフォトダイオード564まで拡大しているか否かを判定する。無効化部72は、上金型12の影が上金型12の最近傍に位置するフォトダイオード564まで拡大していると判定された場合には、そのフォトダイオード564を無効化する。検出部74は、上部テーブル26の下降動作中に、有効な複数のフォトダイオード56の受光状態に基づいて、上金型12と下金型14の間における異物の有無を検出する。【選択図】図1 |
