CARRYING SYSTEM AND CONTROL METHOD THEREOF

To provide a carrying system capable of detecting the inclination of a lifting table with a simple structure.SOLUTION: A carrying system 100 comprises a rack 110, a crane 120, and a control device 150. The rack 110 comprises a plurality of parts to be detected 113. The crane 120 comprises a lifting table 121, a suspension member, a lifting drive device 124, a transfer machine 125 which travels along the lifting table 121, a traveling drive device 129, a position detector 126 for detecting the position of the transfer machine, and a sensor 127 which is mounted on the transfer machine 125 and detects the part to be detected 113. The control device 150 comprises: a height position detector 153 which moves the transfer machine 125 so as to allow the height positions of the plurality of parts to be detected 113 on a storage shelf 112 to be detected in a confirmation mode, and detects the height position of the part to be detected 113 by the position detector 126 and the sensor 127; and an abnormality notification unit for notifying the inclination abnormality of the lifting table 121 based on a plurality of detected height positions.SELECTED DRAWING: Figure 3 【課題】簡単な構成で昇降台の傾きを検出する。【解決手段】ラック１１０と、クレーン１２０と、制御装置１５０と、を備える搬送システム１００であって、ラック１１０は、複数の被検出部１１３を備え、クレーン１２０は、昇降台１２１と、吊持部材と、昇降駆動装置１２４と、昇降台１２１に沿って走行する移載機１２５と、走行駆動装置１２９と、移載機の位置を検出する位置検出装置１２６と、移載機１２５に搭載され、被検出部１１３を検出するセンサ１２７と、を備え、制御装置１５０は、確認モードにおいて、保管棚１１２において複数の被検出部１１３の高さ位置を検出できるように移載機１２５を移動させ、位置検出装置１２６、およびセンサで被検出部１１３の高さ位置を検出する高さ位置検出部１５３と、複数の高さ位置に基づき昇降台１２１の傾き異常を報知する異常報知部と、を備える搬送システム１００。【選択図】図３
