Blade Runner Sheet Stacking Apparatus with Detection Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In bank note checking machines, there is a discrepancy between the number of bank notes counted and those sealed in a bundle due to sheets flying out of the blade-to-blade space before reaching the scraping-out plate, leading to incorrect counting and sealing.
Innovation Solution
A sheet material stacking apparatus with a rotatable blade-type runner, a scraping-out device, and detection systems to ensure sheets are properly stacked, featuring a first detecting device for initial sheet detection and a second detecting device to confirm sheet arrival at the scraping-out plate, with a control device stopping the stacking operation if the sheet fails to reach the plate within a predetermined time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a blade-type runner is used to guide and stack bank notes, then the stacking operation is efficient and automated, but sheets may fly out of the blade-to-blade space before reaching the scraping-out plate, causing counting errors
Solution Approach 1:
The patent employs a detection device that monitors whether bank notes have successfully reached the scraping-out plate. This feedback mechanism allows the system to detect when sheets fail to be properly guided and stacked, enabling corrective action to prevent counting errors while maintaining automated stacking efficiency
Solution Approach 2:
The patent replaces purely mechanical stacking reliance with an automated detection and control system. The detection device and control unit work together to monitor the stacking process and stop operations when anomalies occur, substituting mechanical certainty with sensor-based verification
2Productivity
If sheets that fail to reach the scraping-out plate are still counted as stacked, then the stacking operation continues without interruption, but the number of sealed bank notes does not match the counted number
Solution Approach 1:
The detection device provides real-time feedback on whether bank notes have successfully reached the scraping-out plate. The control unit uses this feedback to stop the stacking operation when sheets are not properly stacked, ensuring that counted notes match sealed notes and preventing counting errors while maintaining operational continuity through automated control
Solution Approach 2:
The system performs self-verification through the detection device that automatically monitors the stacking process. The control unit automatically stops the operation when anomalies are detected, enabling the system to self-correct without external intervention and maintain both productivity and accuracy

AI summary
A sheet material stacking apparatus comprises a shift sensor configured to detect the sheet conveyed by a branching path, a drop-down checking sensor configured to detect that sheet which reaches a scraping-out plate through the rotation of a rotatable blade-type runner, and a transport controller configured to, after a passage of a predetermined time following the detection of the sheet by the shift sensor, start detecting the sheet by using a drop-down checking sensor, and to stop stacking the sheet when the drop-down checking sensor detects no sheet.
