Workpiece Conveyance with Separate Lifting for Lower-Cost Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of workpiece conveyance systems due to the inclusion of elevating machines in all carriages, which increases the overall system expense.
Innovation Solution
A workpiece conveyance system where the elevating machine is configured separately from the on-floor carriage, allowing the under-floor carriage to push up the workpiece, thus eliminating the need for elevating machines in the on-floor carriage and enabling synchronized movement with the conveyance of assembled workpieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If elevating machines are included in all carriages, then workpieces can be raised and lowered, but the system cost increases
Solution Approach 1:
The workpiece conveyance system is divided into two functional parts: on-floor carriages for horizontal transport and a separate elevating machine for vertical movement. This segmentation allows each component to be optimized independently, eliminating the need for expensive elevating machines in every carriage while maintaining full functionality.
Solution Approach 2:
The elevating function is extracted from the on-floor carriages and placed into a separate, dedicated elevating machine. This extraction reduces device complexity and cost by concentrating the elevating capability in one location rather than duplicating it across multiple carriages.
2Manufacturing precision
If multiple on-floor carriages convey workpieces individually, then assembly positioning precision is improved, but conveyance coordination becomes more difficult
Solution Approach 1:
Each on-floor carriage is equipped with sensors and control systems that provide feedback about position, speed, and workpiece status. This feedback enables precise positioning at assembly points while the central control system coordinates multiple carriages to prevent conflicts and ensure smooth operations.
Solution Approach 2:
The conveyance system allows carriages to dynamically adjust their speed and positioning based on real-time conditions. This dynamic control enables precise assembly positioning while maintaining flexible coordination among multiple carriages, as each can adapt its motion to the current system state.
