Conveyance Device Sub-Carriage Steps Gap Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing conveyance devices experience a gap between the carriages and the platform when the conveyance path turns, due to the positional relationship between the main and sub-carriages, leading to inefficiencies in the movement of conveyance targets.
Innovation Solution
A conveyance device with alternately provided main and sub-carriages, where the sub-carriages include steps that can be drawn perpendicular to the movement direction in bending areas, reducing the gap between the carriages and the platform by engaging with guide rails and cover parts that adjust their position to minimize the gap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If sub-carriages are connected movably to main carriages to allow positional adjustment, then the gap between carriages and platform is reduced in bending areas, but the device complexity increases
Solution Approach 1:
The sub-carriages are connected to main carriages through movable connections that allow dynamic adjustment of position. The steps on sub-carriages can be drawn out in bending areas and retracted in straight areas, enabling the system to adapt its configuration dynamically based on the conveyance path geometry, thus reducing gaps in bending areas while maintaining simplicity in straight areas
Solution Approach 2:
The conveyance device is divided into main carriages and sub-carriages with distinct functions. The sub-carriages with drawable steps act as auxiliary segments that can be deployed only where needed (in bending areas), separating the gap-reduction function from the main carriage structure and reducing overall system complexity
2Manufacturing precision
If steps are drawn from sub-carriages in bending areas, then the gap coverage is improved, but the ease of operation decreases
Solution Approach 1:
The steps are configured to be drawn automatically from the sub-carriages based on the conveyance path geometry. The movable connection between sub-carriages and main carriages enables the steps to deploy and retract autonomously as the system moves through bending and straight areas, eliminating the need for manual operation or complex control mechanisms

AI summary
Achieved is a conveyance device including a mechanism which reduces a gap to be generated between each of carriages coupled to each other and a path along which the carriages pass. A conveyance device (1) to be conveyed along a conveyance path (6) includes: a plurality of main carriages (2); and a plurality of sub-carriages (3) that are located between the main carriages and that are connected so as to be movable with respect to the main carriages. The main carriages and the sub-carriages are alternately provided. The sub-carriages each include a step (7) configured to be drawn therefrom in a direction perpendicular to a movement direction of a conveyance path and in an area in which the conveyance path bends.
