Feeder Drive Trains for Continuous Assembly Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing partition assembly machines are inefficient and costly due to the need for manual intervention and frequent stopping and starting, which causes wear and tear, leading to reduced throughput and operational inefficiencies.
Innovation Solution
An assembly machine with a feeder system utilizing multiple drive trains that can alter speed, allowing continuous operation by synchronizing the delivery of components to maintain a constant periodic coupling rate, eliminating the need for manual intervention and reducing wear and tear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the assembler stops between component deliveries to allow manual clearing and reloading, then manual intervention is required and wear and tear increases, but the system can be simpler and easier to operate
Solution Approach 1:
The feeder system is divided into multiple independent drive trains, each capable of transporting components to the assembler independently. This segmentation allows the system to maintain continuous operation by having multiple sources ready to supply components, eliminating the need for stopping and manual intervention while keeping each individual drive train relatively simple
Solution Approach 2:
Components are pre-positioned and staged in the feeder system before being needed by the assembler. The multiple drive trains are prepared in advance with components ready for immediate transfer, allowing the assembler to continue operating without interruption and eliminating the need for manual reloading during operation
2Productivity
If the assembler operates continuously without stopping, then throughput increases and wear and tear decreases, but the feeder system must be more complex to synchronize component delivery
Solution Approach 1:
The drive trains are designed with variable speed capabilities, allowing them to dynamically adjust their operation to match the assembler's needs. This dynamic control enables continuous operation while maintaining flexibility in how components are delivered, simplifying the synchronization requirement by allowing real-time adaptation rather than rigid pre-coordination
Solution Approach 2:
The system incorporates feedback mechanisms where the position and status of components in the feeder system are continuously monitored and used to control the drive trains. This feedback loop automatically synchronizes component delivery with the assembler's operation, eliminating the need for complex manual coordination while enabling continuous operation
3Productivity
If manual workers deliver parts and operate the assembler, then the system is easier to control and maintain, but labor costs increase and operational efficiency decreases
Solution Approach 1:
The feeder system is designed to automatically perform functions previously requiring manual workers, such as positioning components and transferring them to the assembler. The system serves itself by using the motion of the assembler to drive the feeder mechanism, eliminating the need for manual intervention while keeping the overall system relatively simple through passive automation
Solution Approach 2:
The feeder system is designed with multi-functional capabilities where the same mechanical structures serve multiple purposes: transporting components, positioning them for assembly, and synchronizing with the assembler's motion. This universality reduces the need for separate dedicated mechanisms for each function, thereby reducing overall system complexity while achieving high automation

AI summary
An assembling machine with a feeder is provided. The feeder feeds receiving components into an assembler, where a moveable coupling mechanism couples attaching components to the receiving components. Transporting mechanisms coupled to a plurality of drive trains deliver the receiving components across the feeder table and to the assembler. The transporting mechanisms alternate between a plurality of speeds so as to deliver the receiving components to the assembler such that the moveable coupling mechanism may operate at a continuous, periodic rate.
