ARTICLE CONVEYING SYSTEM AND OVERHEAD CARRIER

摘要

This invention provides an overhead carrier for transporting an article on a ceiling of an article conveying system can travel on curves with various curvatures so as to increase the layout flexibility of traveling rails. Driving wheels that move an overhead carrier along traveling rails and non-driving wheels that are rotated separately from the driving wheels are provided on the right and left of the transport direction of the overhead carrier. In a linear section, the driving wheels on the right and left sides are supported by the traveling rails. In a curved section, the inner non-driving wheel is supported by the inner traveling rail while the outer driving wheel is supported by the outer traveling rail.

主权项

1. An article conveying system that transports an article by means of an overhead carrier traveling along a transport track,
the article conveying system including a pair of right and left traveling rails along the transport track on a ceiling of the article conveying system, the overhead carrier including driving wheels that are rotatably supported by the traveling rails in a drivable manner so as to move the overhead carrier along the traveling rails, and non-driving wheels that are rotated separately from the driving wheels, the overhead carrier having the driving wheels and the non-driving wheels on each of right and left of a transport direction, the transport track including a linear section in which the driving wheels on right and left sides of the overhead carrier are respectively supported by the pair of right and left traveling rails, the transport track including a curved section in which the inner non-driving wheel of the overhead carrier is supported by the inner traveling rail while the outer driving wheel of the overhead carrier is supported by the outer traveling rail.
