Conveying apparatus and conveying system with cant surfaces

摘要

A conveying apparatus includes a guide mechanism and a moving body guided by the guide mechanism. The moving body includes a first support, a second support and a holding portion. The first support has a first engagement portion engaged with the guide mechanism. The first support, supported by the guide mechanism, is movable in a first direction. The second support has a second engagement portion engaged with the guide mechanism. The second support, supported by the guide mechanism, is movable in the first direction. The holding portion, supported by the first and the second supports, holds a workpiece. The first engagement portion receives a moment applied thereto by deformation of the moving body, where the moment is opposite in direction to a moment applied to the first engagement portion by a load of the workpiece held by the holding portion.

主权项

1. A conveying apparatus comprising:
a guide mechanism; and a moving body configured to move while being guided by the guide mechanism; wherein the moving body comprises: a first support including a first engagement portion engaged with the guide mechanism, the first support being supported by the guide mechanism so as to be capable of moving in a first direction; a second support including a second engagement portion engaged with the guide mechanism, the second support being supported by the guide mechanism so as to be capable of moving in the first direction; and a holding portion for holding a workpiece, the holding portion being supported by the first support and the second support, the first engagement portion receives a first opposite direction moment applied thereto by deformation of the moving body, the first opposite direction moment being opposite in direction to a moment applied to the first engagement portion by a load of the workpiece when the workpiece is held by the holding portion; a base supporting the guide mechanism, wherein a first cant surface is provided between the first engagement portion and the holding portion, or between the guide mechanism and the base, and a second cant surface is provided between the second engagement portion and the holding portion, or between the guide mechanism and the base, wherein the first and second cant surfaces have respective inner and outer heights; in plan view the inner height of one of the first and second cant surfaces is closer to the other inner height of the first and second cant surfaces than is the outer height of the one of the first and second cant surfaces, and the inner height is higher than the outer height.
