Conveyor Table Transfer Linkage for Guide Rail Misalignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveyor table transfer systems require precise adjustment of linear-motion guide members to ensure smooth movement, leading to unreasonable loads and potential misalignment issues when these members are not perfectly parallel.
Innovation Solution
A conveyor table transfer apparatus featuring a link mechanism with spherical bearings that allows for flexible movement, enabling smooth operation even with low parallelization between guide members, and includes a bias member to suppress backlash, ensuring proper posture and positioning of the movable linear conveyor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If linear-motion guide members are mounted with high degree of parallelization, then smooth movement of movable linear conveyor is achieved, but precise adjustment is required which increases device complexity
Solution Approach 1:
The link mechanism is designed with one or more degrees of freedom, allowing it to dynamically adapt its configuration. This enables the mechanism to automatically compensate for misalignment between guide members during operation, achieving smooth movement without requiring precise initial adjustment of the guide members' parallelization.
2Ease of manufacture
If linear-motion guide members are not parallel, then mounting adjustment is simplified, but unreasonable load is applied to drive member or movable member
Solution Approach 1:
The link mechanism's degree of freedom allows it to change its geometric parameters (angles, positions) in response to load conditions. When guide members are not perfectly parallel, the mechanism adjusts its configuration to distribute forces evenly, preventing unreasonable load concentration on the drive member or movable member while maintaining ease of mounting.
3Adaptability or versatility
If link mechanism has degree of freedom, then compensation for guide member misalignment is achieved, but mechanism complexity increases
Solution Approach 1:
The link mechanism is segmented into multiple connectable components that can be assembled in series. This segmentation allows the mechanism to achieve the necessary degrees of freedom for compensation while keeping each individual component relatively simple, balancing adaptability with structural simplicity.

AI summary
A conveyor table transfer apparatus includes a link mechanism connects the drive member driven by a motor (drive source) and a movable member supporting the movable linear conveyor. The link mechanism has one or more degrees of freedom. The degree of freedom of the link mechanism causes the link mechanism to bend in response to a degree of parallelization between the linear-motion guide rail and the linear-motion guide rail, making it possible to suppress load to be applied to the drive member or the movable member. As a result, it becomes possible to move the movable linear conveyor smoothly without requiring precise adjustment in mounting of the drive member and the movable member on the linear-motion guide rail and the linear-motion guide rail respectively.
