Horizontal conveyance mechanism for self-propelled carriage

Abstract

A conveyance mechanism having rails (10) horizontally and vertically laid in a building, racks (20) laid along the rails, wheels (31, 32) for traveling on the rail, and a self-propelled carriage (30) having pinions (33, 34) meshing with the racks and a drive section for the pinions and on which a load is placed. The rails have a curve section in which they change the direction from horizontal to vertical or from vertical to horizontal, and also have a vertical section continuing to the horizontal section. In the two sections above, the rails have rails (11) for the pinions, having the racks meshing with the pinions, and also have rails (12) for the travel wheels, installed in parallel with and separated from the rails for the pinions. The carriage have, on its left and right sides, the pinions meshing with the rails for the pinions and the travel wheels supported on the rails for the travel wheels. Also, the rails for the pinions and the rails for the travel wheels are arranged so that the carriage can move in a horizontal position in the curve section and the vertical section continuing to the curve 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...

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 tu
