Sheet Storing Apparatus Bag Sealing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet storing apparatuses face issues with defective sealing when sheets, such as banknotes, get stuck in the bag opening, leading to incomplete sealing.
Innovation Solution
The apparatus employs a banknote storing mechanism with a pantograph and pressing plate system that compresses and positions banknotes within the bag, ensuring proper alignment and space for subsequent banknotes, preventing overflow and ensuring the bag can be heat-sealed effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sheets are stored in a bag using conventional heating members for sealing, then the bag can be sealed, but sheets may get stuck in the opening causing defective sealing
Solution Approach 1:
The pressing plate performs preliminary action by compressing sheets into the bag before the heating members seal the opening. This ensures sheets are properly positioned and prevents them from protruding or getting stuck during the sealing process, thereby eliminating defective sealing caused by sheet interference.
Solution Approach 2:
The pressing plate acts as an intermediary between the sheet storage mechanism and the sealing mechanism. It mediates the transition by ensuring sheets are fully contained and compressed before the heating members make contact with the bag opening, preventing direct interference between sheets and the sealing process.
2Ease of manufacture
If heating members are used to close the bag opening, then the bag can be sealed, but sheets may interfere with the sealing process
Solution Approach 1:
The pressing plate executes preliminary compression of sheets into the bag before the heating members are activated for sealing. This preliminary action ensures the sealing area is clear of sheet interference, allowing the heating members to function effectively and reliably without obstruction.
Solution Approach 2:
The pressing plate maintains continuous pressure on the sheets during the sealing process, ensuring sheets remain properly positioned throughout the entire sealing operation. This continuous action prevents sheets from shifting or interfering with the heating members, ensuring complete and reliable sealing.
