Abstract

제어장치가 정확한 일정 정지위치를 알 수 있도록 하는 것을 목적으로 한다.The purpose is to allow the control device to know the exact constant stop position.

상하방향에 평행하도록 상방광전센서(3)와 하방광전센서(4)가 승강대(1)쪽에 설치되어 있고, 차폐판(5)이 마스트(2) 쪽에 부착되어 있으며, 이것들에 의하여 승강대(1)가 포오크를 진출시킨 상태에서 승강하는 구역이 확정된다. 승강대(1)는 이 구역 내에서 하물을 인수인도하기 때문에, 승강대(1)를 승강시키는 체인이 신축한다. 따라서, 체인을 구동하는 모터의 회전을 검지하는 인코더의 값과 기억하고 있었던 일정 정지위치의 값의 차를 산출하여, 기억하고 있었던 값을 보정하여서 갱신한다.The upper photoelectric sensor 3 and the lower photoelectric sensor 4 are provided on the lifting table 1 side in parallel with the up and down direction, and the shielding plate 5 is attached to the mast 2 side, whereby the lifting table 1 The area to be elevated is confirmed with the fork advancing. Since the platform 1 takes over goods in this area, the chain which elevates the platform 1 is extended. Therefore, the difference between the value of the encoder which detects the rotation of the motor driving the chain and the value of the fixed stop position stored is calculated, and the stored value is corrected and updated.
