To provide a steel piece transporting device capable of more effectively transporting steel pieces with a hanging tool by detecting the pile height of piled steel pieces with a simpler configuration.SOLUTION: A steel piece transporting device lowers a hanging tool 3c toward piled-state steel pieces 2 and hangs up the steel pieces. The steel piece transporting device comprises: a height detection part 6 consisting of a photoelectric sensor which emits light from a side direction toward a side of the piled-state steel pieces 2; a contact-type sensor 5 provided on the hanging tool 3c and detecting the upper surface of the piled-state steel pieces 2; a descent speed setting part 11; and a deceleration-start height setting part 7Aa. The descent speed setting part sets a low speed that slows down the descent speed of the hanging tool 3c when it is determined that the position of the hanging tool 3c descending toward the upper surface of the piled-state steel pieces 2 reaches the deceleration-start height. The deceleration-start height setting part sets the deceleration-start height according to the height of a detection position where the steel piece is detected by the height detection part 6, and the lower the height of the detection position is, the lower the deceleration-start height is set.SELECTED DRAWING: Figure 1
【課題】より簡易な構成で山積み状態の鋼片の山高さを検出し吊り具による鋼片の搬送をより効率的に行う。【解決手段】山積み状態の鋼片2に向けて吊り具3cを下降して鋼片を吊り上げる鋼片搬送装置である。山積み状態の鋼片2側に向けて横方向から光を照射する光電センサからなる高さ検出部6と、吊り具3cに設けられ、山積み状態の鋼片2の上面を検出する接触型センサ5と、山積み状態の鋼片2の上面に向けて下降する吊り具3cの位置が減速開始高さとなったと判定したら、吊り具3cの下降速度を減速した低い低速とする下降速度設定部11と、高さ検出部6で検出する鋼片有りの検出位置の高さに応じて減速開始高さを設定し、検出位置の高さが低いほど減速開始高さを低く設置する減速開始高さ設定部7Aaと、を備える。【選択図】 図1
