LANDING DETECTION MECHANISM AND METHOD OF MANUFACTURING LANDING DETECTION MECHANISM

摘要

PROBLEM TO BE SOLVED: To provide a landing detection mechanism and a method of manufacturing the landing detection mechanism capable of detecting the landing of a spreader at high accuracy and stably.;SOLUTION: A detection rod 10 formed with a rod-shaped body having the vertical direction z as an axial direction is disposed in a spreader in a state capable of moving in the vertical direction z. A target member 11 is fixed to the detection rod 10, and a landing detection sensor 12 is disposed at the side of the detection rod 10. A detected part 16 is formed at a position facing the landing detection sensor 12 when the target member 11 becomes a same height as the landing detection sensor 12, and the detected part 16 is formed in an arc shape setting the central axis of the detection rod 10 as the center.;SELECTED DRAWING: Figure 8;COPYRIGHT: (C)2018,JPO&INPIT
