Linear Drive Signal Bar for Maintenance Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Linear drives, particularly in production machines, are difficult to maintain due to the lack of effective monitoring and indication of segment and runner status, leading to inefficiencies and potential downtime.
Innovation Solution
A signal bar system with optical signal transmitters and sensors is integrated into the linear drive to display the position, speed, and status of runners and segments, using a processing unit to control the signal bar and provide real-time feedback on maintenance needs, allowing for easy identification of components requiring service or replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a linear drive with segments and runners is used for positioning goods and workpieces, then positioning capability and productivity are improved, but maintenance difficulty increases due to lack of status monitoring
Solution Approach 1:
The patent implements a feedback mechanism by equipping each segment with a sensor that detects the position of runners and transmits this information to a control unit. The control unit processes the data and activates corresponding signal transmitters on the signal bar to visually indicate the status of each segment and runner position. This feedback system enables real-time monitoring of the linear drive's operational state, allowing operators to quickly identify segments requiring maintenance without shutting down the entire system.
Solution Approach 2:
The patent introduces a signal bar as an intermediary visual interface between the complex internal components (segments and runners) and the operator. The signal bar translates sensor data into intuitive visual signals, making the status of individual segments and runner positions immediately apparent. This intermediary device bridges the gap between the automated positioning system and human operators, facilitating easy monitoring and maintenance decisions.
2Reliability
If multiple segments with sensors and control units are integrated into the linear drive, then status monitoring capability is improved, but device complexity increases
Solution Approach 1:
The patent divides the linear drive into discrete segments, each equipped with its own sensor and control unit. This segmentation allows independent monitoring of each segment's status and the position of runners on that segment. The modular architecture means that each segment can be monitored and maintained independently, reducing the complexity of overall system management despite the increased number of components.
Solution Approach 2:
The control units are designed with multi-functionality, serving both to control the linear drive operation and to process sensor data for status monitoring. The signal bar serves multiple purposes by indicating both the position of runners and the operational status of segments through different signal patterns. This multi-functionality reduces the need for separate dedicated components, thereby managing system complexity while maintaining comprehensive monitoring capability.

AI summary
The invention relates to a signal bar (Sig) with a sensor (PS), a segment (Seg) with such a signal bar (Sig) and a sensor (PS), a linear actuator (LA), and a system. The signal bar (Sig) is assigned to at least one segment (Seg). The signal bar (Sig) serves to indicate the state of the segment (Seg) and/or the state of a runner (L), wherein the at least one runner (L) is moved through the respective segment (Seg). The state is assigned by a sensor (PS) that is assigned to the respective segment (Seg). The state can additionally be transmitted to the signal bar (Sig) from a computer network, in particular a service cloud. Examples of a state of the runner (L) are its current position (x-actual) and whether it requires maintenance. Examples of the state of the respective segment (Seg) are its temperature or its functionality.The status is advantageously presented to a user who maintains the linear drive (LA) of the system. Thus, the invention reduces the maintenance time for the linear drive (LA) because the operator of the linear drive (LA) can immediately see the status of the respective runner (L) or segment (Seg).
