Conveying Apparatus Runout Detection in Restricted Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveying apparatuses face issues with objects deviating from their normal position due to narrow areas in processing devices, leading to potential collisions or misalignment during vertical conveyance.
Innovation Solution
Incorporation of first and second detection devices to identify runouts from normal positions in non-restricted and restricted areas, respectively, with a controller adjusting conveyance operations based on these detections to prevent issues in both areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the support conveying the object passes through the structure with a narrow interior, then the object can be conveyed vertically through the processing device, but the object or support may contact or collide with the structure due to displacement or deviation
Solution Approach 1:
The detection devices detect runout from the normal position in advance before the object or support contacts the structure. The controller uses this advance detection information to adjust the conveyance operation, preventing contact or collision with the structure while maintaining continuous vertical conveyance through the processing device.
2Reliability
If the conveyance operation is slowed down to prevent contact with the structure, then safety is improved, but conveyance efficiency decreases
Solution Approach 1:
The controller dynamically adjusts the conveyance operation based on real-time detection results. When runout is detected to be within a safe range, normal conveyance speed is maintained. When runout approaches dangerous levels, the controller selectively slows down or pauses conveyance only in the restricted area, rather than reducing speed throughout the entire conveyance path, thus optimizing the balance between safety and efficiency.
3Reliability
If detection devices and control systems are added to prevent contact with the structure, then conveyance safety is improved, but device complexity increases
Solution Approach 1:
The detection devices continuously monitor the runout position of the object or support relative to the normal position. This detection information is fed back to the controller, which automatically adjusts the conveyance operation in response. This closed-loop feedback system provides intelligent, adaptive safety control without requiring complex mechanical safety devices or extensive manual intervention.

AI summary
A conveying apparatus is capable of conveying an object supported by a support along a vertical direction in a non-restricted area and a restricted area narrower than the non-restricted area. The conveying apparatus has a first detection device, a second detection device and a controller. The first detection device detects whether a runout of the conveyed object supported by the support from a normal position is within or outside the non-restricted area. The second detection device detects whether the runout from the normal position of the object supported by the support is within or outside the restricted area. The controller controls the conveyance operation of the object to be conveyed by the support based on the detection results of the first detection device and the second detection device.
