Abstract
The overhead traveling vehicle system includes a track having a plurality of first rails extending in an X direction and a plurality of second rails extending in a Y direction arranged in a grid, and a traveling vehicle traveling on a pair of the first rails adjacent to each other in the Y direction and traveling on a pair of the second rails adjacent to each other in the X direction, in which each of the first rail and the second rail has a first surface on which a cell recognition mark is disposed and a second surface on which a position recognition mark is disposed, the second surface, when viewed from a center of a cell in plan view, being disposed outside the first surface and being inclined toward the traveling vehicle side with respect to the first surface.
Claims5
A tracked cart system, comprising:
- a track in which a plurality of first rails extending in a first direction and a plurality of second rails extending in a second direction orthogonal to the first direction are disposed in a grid;
- and
- a tracked cart configured to move in the first direction when a traveling part travels on a pair of the first rails adjacent to each other in the second direction, and to move in the second direction when the traveling part travels on a pair of the second rails adjacent to each other in the first direction, wherein
- the tracked cart has
- a first sensor configured to acquire first information from a first mark indicating the first information, and
- a second sensor configured to acquire second information that is information different from the first information from a second mark indicating the second information,
- each of the first rail and the second rail has
- a first surface that faces the first sensor and on which the first mark is disposed, and
- a second surface that faces the second sensor and on which the second mark is disposed, the second surface having, when viewed from a center of a cell serving as a space enclosed by the pair of first rails and the pair of second rails in plan view, the second surface that is disposed outside the first surface and is inclined on the tracked cart side with respect to the first surface.
