Turn table transport carriage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional turn table transport carriages require a wide passage for carrying and attaching/detaching turn tables, leading to poor space efficiency, especially in index type polishing apparatuses, where the need for horizontal operation increases the required space and reduces productivity.
Innovation Solution
A turn table transport carriage with an inclination mechanism that allows the turn table holding section to be inclined, reducing the width of the carriage and passage, and enabling easier attachment and detachment with reduced space requirements by eccentrically arranging the holding section and using a support base with a hydraulic or chain-based elevating mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the turn table transport carriage operates in a horizontal state for attaching and detaching turn tables, then the ease of operation is improved, but the width of the carriage and passage increases, reducing space efficiency
Solution Approach 1:
The turn table holding section is designed to be movable between horizontal and inclined states. During attachment/detachment operations, it transitions to a horizontal state for ease of operation. During transport, it transitions to an inclined state (e.g., 30-60 degrees) to reduce the projected width and fit through narrow passages between polishing apparatuses.
Solution Approach 2:
The solution addresses the width problem by utilizing the vertical dimension. By inclining the holding section, the effective width required for passage is reduced while maintaining the same turn table capacity. This dimensional transformation allows the system to operate in confined spaces without sacrificing operational ease.
2Area of stationary object
If the passage width between adjacent polishing apparatuses is reduced to improve space efficiency, then the area occupied is reduced, but the ease of attaching and detaching turn tables deteriorates
Solution Approach 1:
The holding section dynamically adjusts its orientation based on operational requirements. When positioned between polishing apparatuses with narrow gaps, it inclines to clear the passage. When positioned at the polishing apparatus for attachment/detachment, it horizontalizes to provide adequate working space and ease of operation.
Solution Approach 2:
The inclined holding section acts as an intermediary mechanism that bridges the gap between narrow passage constraints and adequate operational space requirements. It allows the turn table to be transported through tight spaces while still enabling proper attachment/detachment operations when positioned correctly.
3Productivity
If a heavy turn table (e.g., 80 kg stainless steel or 40 kg ceramics) is frequently attached and detached, then the productivity is improved through multiple polishing operations, but the safety and ease of handling deteriorates
Solution Approach 1:
The turn table holding section incorporates self-leveling and self-locking mechanisms. When the holding section is inclined during transport, gravity helps secure the heavy turn table in position. When horizontalized for operation, automatic locking mechanisms engage to secure the turn table, reducing the need for manual handling and improving safety during frequent attachment/detachment operations.
