RFID Mold Tracking for Faster Production Plant Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing production plants, such as injection molding machines, face delays in starting production due to the sequential nature of setting operating parameters after installing injection molds, which requires manual search and conveyance by personnel.
Innovation Solution
Implementing a method with RFID transponders and reading devices to determine the location and movement of machine tool parts, allowing for automated control signals to be generated for tasks like door control, temperature settings, and material preparation based on the movement and location data of machine tool parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual search and conveyance of injection molds by personnel is used, then the process is simple to implement, but production delays occur due to sequential setup steps
Solution Approach 1:
The system performs preliminary actions by detecting the injection mold's location and movement in advance using RFID technology. The control device automatically prepares operating parameters and initiates setup processes before the mold is actually installed in the injection molding machine, eliminating the sequential delay where parameters could only be set after physical installation.
Solution Approach 2:
The system enables self-service by automating the detection, tracking, and parameter configuration process. The RFID reading devices automatically detect the mold's presence and location, the control device automatically retrieves and sets the appropriate operating parameters, and the entire setup process occurs without manual intervention from personnel, significantly reducing setup time.
2Extent of automation
If RFID reading devices are positioned at a distance from the machine tool, then automated detection is achieved, but the system complexity increases
Solution Approach 1:
The RFID reading devices are designed with multi-functionality, serving both as detection devices for locating injection molds and as communication nodes in the automated control system. This universal approach consolidates multiple functions into single components, reducing overall system complexity despite the distributed architecture.

AI summary
A method for controlling and/or monitoring a production plant for producing a multiplicity of articles, wherein the production plant has a machine tool; a machine tool part which interacts with the machine tool in order to produce an article; an RFID transponder connected to the machine tool part; two RFID reading devices which are arranged at a distance from one another and from the machine tool; and a control device which is connected to the RFID reading devices via data lines. The method includes determining a first location of the machine tool part at a first time with the first RFID reading device and/or with the second RFID reading device; and determining a second location of the machine tool part at a second time, which temporally follows the first time, with the first RFID reading device and/or with the second RFID reading device; and outputting at least one control signal with the control device on the basis of the first location and the second location.
