Automated Cover Opening for Bank Note Processing Malfunctions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In bank note processing machines with multiple modules, operators face challenges in quickly identifying and accessing malfunctioning zones, requiring manual intervention while ensuring safety and ergonomics.
Innovation Solution
The apparatus automatically opens the cover of the relevant processing zone associated with a detected event, stopping the machine for safety and guiding the operator directly to the intervention point, with optional confirmation and signaling for added safety, using actuators and gas pressure springs for movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator manually opens covers to access malfunctioning zones, then the operator can intervene to eliminate malfunctions, but the operator must expend energy to open heavy covers and must locate the correct cover among multiple modules
Solution Approach 1:
The cover opening system serves itself by automatically opening the relevant cover in response to a malfunction detection, eliminating the need for manual operator intervention to open covers. The system detects the malfunction location and autonomously opens the corresponding cover, making the system self-serve the operator's need for access.
Solution Approach 2:
An actuator serves as an intermediary between the malfunction detection and the cover opening action. The actuator receives signals from the detection system and translates them into mechanical motion to open the cover, mediating between the control system and the physical cover.
2Ease of operation
If multiple covers are automatically opened simultaneously, then all malfunctioning zones are accessible, but safety risks increase for persons in the vicinity
Solution Approach 1:
The system performs preliminary actions by stopping the machine before opening covers and providing advance warning signals. This preliminary stopping and warning sequence prepares the environment for safe cover opening, eliminating the hazard of machine operation during cover opening.
Solution Approach 2:
The system applies preliminary anti-action by implementing safety measures before the potentially harmful cover opening occurs. The machine stop and warning signals counteract the potential harm by creating a safe state before the cover opening action takes place.
3Object-affected harmful factors
If the machine stops before cover opening for safety, then operator and persons in vicinity are protected, but productivity is reduced during malfunction handling
Solution Approach 1:
The machine state transitions dynamically between operating and stopped states based on the cover position. When covers are closed, the machine operates; when covers open, the machine stops. This dynamic adaptation allows maximum productivity when safe and ensures safety when covers are open.
Solution Approach 2:
The system uses feedback from cover position sensors to control machine operation. The detection of open cover positions feeds back to the control system, which then stops the machine, creating a closed-loop safety mechanism that automatically responds to cover state changes.

AI summary
The invention relates to an apparatus (1) for processing documents of value, in particular bank notes, and a method for operating such an apparatus (1). The apparatus (1) includes several processing zones (2, 3, 4, 5, 11, 12, 13), such as for example an input module (2), an operating module (3) and an output module (4). The apparatus (1) is further set up to detect events in the processing zones (2, 3, 4, 5, 11, 12, 13), which require an intervention of an operator. The processing zones (2, 3, 4, 5, 11, 12, 13) each have at least one cover (6), which, dependent on such a detected event, is automatically opened without intervention of the operator.
