Horizontal transport mechanism for self-propelled carriages

Abstract

A conveying mechanism having a track (10) laid horizontally and vertically in a building, a rack (20) laid along the track, traveling wheels (31, 32) traveling on the track, and a self- A carriage (30) is propelled, said carriage has a pinion (33, 34) meshing with said rack and a drive unit of said pinion, and a load is mounted on said carriage. The track has a curved section that changes direction from horizontal to vertical or vice versa, and has a vertical section continuing the curved section. In the above two sections, the track includes a pinion track (11) having a rack meshed with the pinion, and a traveling wheel track (11) arranged parallel to and separated from the pinion track ( 12). The vehicle frame has, on its left and right sides, a pinion gear meshed with the pinion rail and a traveling wheel supported on the traveling wheel rail. In addition, the pinion rail and the traveling wheel rail are provided so that the vehicle frame can move in a horizontal posture in a curved section and a vertical section following the curved section.

Description

technical field [0001] The present invention relates to a horizontal conveying mechanism for making a self-propelled vehicle frame always travel in a horizontal posture in a conveying system for moving a conveying body composed of a container and a vehicle frame along a plurality of floors of a building or the like. Tracks laid horizontally on the floor and along tracks laid vertically (vertically) on the walls, and loads are unloaded from containers to stations arranged along the tracks and loaded from the stations to the containers input loads such as documents, parts, etc. Background technique [0002] This type of delivery system is widely used because they can automatically transport documents, mail, stationery, etc. in offices, medical records in hospitals, parts and products in factories, and deliver items such as samples, Reagents and other loads. [0003] This transportation system is constituted by rails laid horizontally and vertically in a building, carriages t...

AI Technical Summary

Problems solved by technology

However, it is known that when there is a heavy load on one side in a container suspended by a gyroscopic device, it is difficult to maintain a horizontal attitude due to the container tilting under the action of the unbalanced load

[0006] In addition, since a gyro device is used to always maintain the horizontal attitude of the container and the vehicle frame travels by turning (turning) from the horizontal track to the vertical track, the turning space of the container and the turning travel space of the vehicle frame are required, thereby making the vehicle in the track The radius of curvature of the segment between the horizontal segment and the vertical segment inevitably increases

As a result, there is also the problem that not only the whole system becomes larger, but also the delivery system cannot be installed due to the excessively large radius of curvature in some places
