Encoder Memory Tool Setup for Cross-Machine Tool Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for setting and managing tool information in machines, such as robots and machine tools, require pre-prepared files and separate data management, which is cumbersome and inefficient, especially when tools need to be reattached to different machines over time.
Innovation Solution
A controller with a detachable memory that stores and reads tool setting and condition information, allowing for automatic tool setup and continuous management without the need for additional equipment or operations, using a memory attached to the encoder of the tool driven by a motor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If tool setting information is stored in pre-prepared files and read by the controller, then tool setting can be automated, but additional data management operations and file preparation are required
Solution Approach 1:
The patent combines the tool setting information storage function directly into the tool's encoder memory, merging the data storage function with the existing encoder component. This eliminates the need for separate file preparation and external data management systems, as the tool itself carries its own setting information.
Solution Approach 2:
The tool becomes self-sufficient by storing its own setting information in the encoder's memory. When the tool is attached to a machine, the controller automatically reads the setting information from the tool's encoder without requiring external file preparation or manual data entry, enabling the tool to serve itself.
2Reliability
If tool setting information is stored externally and managed separately, then tool conditions can be tracked, but continuous management across different machines becomes cumbersome
Solution Approach 1:
The encoder's memory serves multiple functions: it stores both the tool's setting information and its condition information (such as operating time). This universal storage capability within the tool itself enables continuous tracking across different machines without requiring separate management systems.
Solution Approach 2:
The tool's encoder acts as an intermediary that carries both setting and condition information between different machines. When the tool is moved from one machine to another, the encoder automatically transfers the relevant data, eliminating the need for external data management operations.
3Loss of information
If a separate memory device is added to store tool information, then data can be retained, but the tool structure becomes more complex
Solution Approach 1:
The patent merges the memory function into the existing encoder structure. The encoder, which is already an integral part of the motor-driven tool for position feedback, now also stores tool setting and condition information in its memory, eliminating the need for separate memory devices.
Data Source
AI summary
A control device controls a tool having a memory and removably attached to a machine. The control device includes a tool information reading unit that reads at least one of tool setting information and tool status information written in the memory of the tool, and a tool setting unit that sets the tool on the basis of at least one of the read tool setting information and tool status information. The tool is driven by a motor having an encoder, and the memory is attached to the encoder.
