Abstract

There is provided a device for conveying articles put on a loading base while horizontally holding the loading bases which are moving circulatively in a vertical plane by a single endless chain.

Independent Claims | See all claims (1)

  1. 1.1. In a conveyor having loading bases for moving articles circulatively in a vertical plane while holding the articles in a horizontal position, the improvement comprising a single endless chain which is adapted to move circulatively in a vertical plane;a plurality of bearings mounted on said chain;a plurality of guide rods mounted to said chain, each guide rod being rotatable through a bearing about a horizontal axis orthogonal to said chain;a loading base fixed to one end of each of said guide rods and a guide plate having its inside face fixed to the opposite end of each guide rod;an outer roller mounting rod and an inner roller mounting rod having a shorter length than the length of the outer roller mounting rod projecting from an outer face of the guide plate in parallel with the guide rod in a vertically spaced position and in a horizontally spaced position, respectively, relative to the point of fixation of said guide rod to said guide plate:an annular outer guide rail along which an outer roller is rotatably mounted and an inner annular guide rail along which an inner roller is rotatably mounted disposed side by side in parallel with said chain in a vertical plane with a horizontal spaced distance between the opposite end of the guide rod and the inner roller mounting rod being a phase difference in a longitudinal direction, and a vertically downward spaced distance between the opposite end of the guide rod and the outer roller mounting rod being a phase difference in a vertical direction,said annular inner guide rail having a passageway in each of both end reversing positions to allow passage therethrough of the outer roller mounting rod, whereby each loading base circulates in a vertical plane while maintaining a horizontal position.
