Sheet Storage Bag Closure to Prevent Jamming During Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet storage apparatuses face issues with sheets getting jammed during the closing process, particularly when closing elements move and apply force, causing banknotes to bend or fall, leading to incomplete sealing.
Innovation Solution
A sheet storage apparatus with a holding unit that maintains sheets in a stacked position, and closing units that move inwardly to avoid bent ends, followed by sealing units that seal from an outer position, all controlled by a control unit to ensure proper sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If closing elements move while facing each other to close the transport container, then the container can be sealed, but sheets may fall or bend and get jammed between the closing elements
Solution Approach 1:
The support member is positioned in advance within the transport container to provide continuous support for the sheets during the closing process. This preliminary positioning prevents sheets from falling or bending before the closing elements complete their sealing action, thereby eliminating the jamming issue while maintaining reliable sealing.
Solution Approach 2:
The support member acts as an intermediary element between the sheets and the closing elements. It provides a stable surface that prevents direct contact between falling/bending sheets and the moving closing elements, thereby preventing jamming while allowing the closing elements to perform their sealing function effectively.
2Reliability
If closing elements apply force to close the transport container, then sealing is achieved, but sheets without support may bend or fall
Solution Approach 1:
The support member is installed in advance within the transport container to maintain sheet alignment before the closing elements apply force. This ensures sheets remain properly positioned and supported throughout the closing process, preventing bending or falling while achieving reliable container closure.
Solution Approach 2:
The support member serves as an intermediary structure that distributes the force applied by closing elements and provides continuous support for sheets. This prevents sheets from bending or falling under the closing force while ensuring effective container closure.

AI summary
The sheet storage apparatus of the present disclosure includes an attachment unit to which a storing bag for sheets is attached; a holding unit that holds the sheets toward an inner side in a storage direction of the storing bag attached to the attachment unit, the sheets being stacked and stored in the storing bag; and a closing unit that closes an entrance of the storing bag by sandwiching the storing bag from outside thereof. The closing unit closes the entrance by moving from a first position to a second position, the first position being a position before the closing unit starts sandwiching the storing bag, the second position being a position when the closing unit sandwiches the storing bag. The closing unit passes through the inner side in the storage direction than the first position between moving from the first position to the second position.
