Feeder Trace Logging via Shared Memory in the Setting Table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems face challenges in saving large amounts of trace logs from multiple feeders due to space constraints and high costs associated with large-capacity trace memory, which is necessary for investigating feeder issues effectively.
Innovation Solution
A feeder trace log saving system that utilizes a shared trace memory linked to identification information of each feeder, where trace logs are output and saved by the component mounter's control section during operation, eliminating the need for individual feeder memory and reducing CPU load, allowing for cost-effective and efficient logging without compromising productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If trace memory with large capacity is loaded in each feeder, then trace logs can be saved reliably for problem investigation, but feeder size increases and costs greatly increase
Solution Approach 1:
The patent merges the trace memory resources from individual feeders into a single shared trace memory located in the feeder setting table. Multiple feeders write their trace logs to this shared memory space, eliminating the need for each feeder to have its own large-capacity memory. This combining approach maintains reliable trace log saving while dramatically reducing the total memory capacity required and lowering costs.
Solution Approach 2:
The patent introduces the feeder setting table as an intermediary between the feeders and the trace memory. The communication control section in the feeder setting table manages the collection and storage of trace logs from multiple feeders. This intermediary structure allows feeders to remain compact while still enabling comprehensive trace log saving through the centralized memory resource.
2Reliability
If trace memory with large capacity is loaded in each feeder, then trace logs can be saved reliably for problem investigation, but costs greatly increase due to high quantity of feeders
Solution Approach 1:
The patent combines multiple small-capacity memory resources into one shared large-capacity memory in the feeder setting table. Instead of purchasing and installing expensive large-capacity memory in each of the many feeders, the system uses a single shared memory resource that serves all feeders. This dramatically reduces the total cost while maintaining the ability to save trace logs from all feeders reliably.
Solution Approach 2:
The shared trace memory in the feeder setting table serves a universal function for all feeders, rather than each feeder having dedicated memory. The communication control section manages multiple feeders through this single memory resource, making the system more cost-effective while maintaining full traceability of all feeder operations.
3Reliability
If control section saves multiple feeder trace logs during operation, then comprehensive trace logs are saved, but CPU load increases and productivity decreases
Solution Approach 1:
The patent implements self-service by enabling feeders to autonomously write their own trace logs to the shared memory without requiring the component mounter's control section to intervene. Each feeder's control section independently manages its own log writing operations, freeing the main control section from CPU-intensive log management tasks and preventing productivity degradation.
Solution Approach 2:
The patent segments the trace log saving function from the main control section and distributes it to individual feeders. Each feeder independently handles its own log writing to the shared memory, dividing the overall log management task into independent parallel operations. This segmentation prevents the main control section from becoming a bottleneck, maintaining high productivity while ensuring complete trace log saving.

AI summary
A trace memory that stores trace logs of multiple feeders set on a feeder setting table of a component mounter is provided in the feeder setting table, and while the component mounter is operating, trace logs of each feeder are output from the control sections of the multiple feeders on the feeder setting table to the feeder setting table, and are stored by a communication control section of the feeder setting table in the trace memory linked to identification information of each feeder. By this, it is possible to save trace logs from multiple feeders on the feeder setting table all together in a shared trace memory, such that it is not necessary to load trace memory on each feeder, thereby meeting requirements of compact feeders and lower costs.
