Conveying Rail Tilt Geometry for Stable Vehicle Member Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing object conveying systems experience tilting and impact issues when a vehicle member enters a rail due to wheel vibrations, which are mitigated by lowering the rail to suppress vibrations.
Innovation Solution
The system incorporates a rail design with a tilt portion and horizontal portion, where wheels move along the rail to correct the tilt angle of the vehicle member, ensuring it remains horizontal upon entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the rail is dropped to a lower position to suppress vibration, then vibration is reduced, but the vehicle member becomes tilted after entering the mounting table
Solution Approach 1:
The rail is designed with a tilt portion that pre-adjusts the vehicle member's angle before it enters the mounting table area. This preliminary tilting action compensates for the downward drop of the rail, ensuring the vehicle member returns to a horizontal position without excessive vibration suppression causing unwanted tilting.
Solution Approach 2:
The rail's geometric parameters are modified by introducing a tilt portion with specific inclination angles. This changes the rail's profile from a simple horizontal or downward-sloping structure to one that actively manages the vehicle member's orientation, transforming the vibration suppression mechanism into a dual-function system that also corrects tilt angle.
2Ease of operation
If the wheels enter the rail along the bridging portion, then the vehicle member can move between stopping points, but impacts and vibrations are generated at the wheel-rail contact point
Solution Approach 1:
The tilt portion of the rail is designed with a curved or oblique surface rather than a sharp angle or flat transition. This curved geometry allows the wheels to gradually ascend the rail surface, distributing the impact over a longer period and reducing the shock wave generated during wheel-rail contact.
Solution Approach 2:
The rail is designed with a three-dimensional tilt portion that extends both horizontally and vertically, creating an oblique path for the wheels. This multi-dimensional approach allows the wheels to follow a smoother trajectory into the rail, reducing impact by utilizing both horizontal and vertical components of motion.

AI summary
The disclosure discloses an object conveying system including an object conveying apparatus and a mounting table. The object conveying apparatus includes a traveling member, the vehicle member, and a transporting member. A rail extending along a horizontal direction is disposed between the object conveying system and the mounting table. A horizontal moving mechanism of the vehicle member moves back and forth along the rail. The rail includes a tilt portion and a horizontal portion. The tilt portion extends obliquely in a direction away from the object conveying apparatus and upward in the up-down direction. While the horizontal moving mechanism is moving away from the object conveying apparatus, a first wheel and a second wheel move along the rail. When the horizontal moving mechanism moves to the mounting table, and a boundary of the tilt portion and the horizontal portion is disposed between the first wheel and the second wheel.
