Moving body system
First Claim
1. A moving body system comprising a moving body that moves along a moving path and a detected member laid along the moving path, the moving path system being characterized in that:
- the detected member comprises a large number of mark members in a direction in which the moving body moves and the moving body comprises detecting means for detecting the mark members of the detected member, each of the mark members comprises a detected portion that can be detected by the detecting means and a non-detected portion that is not detected by the detecting means, the detected member is configured like comb teeth in which a comb tooth portion is the detected portion, while a void between the comb teeth is the non-detected portion, the width of the detected portion in the moving direction of the moving body is equal to that of the non-detected portion in the moving direction of the moving body, the detecting means comprises first detecting means and second detecting means arranged in the moving direction of the moving body, and the moving path of the moving body has a branching portion that branches to at least two paths, and a second detected member is provided on each of the branching paths, while the moving body is provided with second detecting means for detecting the second detected member.

Abstract
It is an object of the present invention to provide a moving body system which can determine the moving position of a vehicle, stacker crane, or other moving body wherever on a moving path having a branching portion or a joining portion the moving body is, the system being able to precisely stop the moving body at any position and enabling the moving body to move fast to a stop position. A moving body system includes a vehicle 1 moving along running rails 2, 2 constituting a moving path having a joining portion and a detected member 20 laid along the running rails 2, 2. The detected member 20 includes a large number of mark members 21, 21, . . . in a direction in which the vehicle 1 moves. The vehicle 1 includes a first detecting sensor 11 and a second detecting sensor 12 which detect the mark members of the detected member 20.
