Movable Sheet Stacker for Stable Multi-Size Sheet Binding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing post-processing apparatuses struggle with stabilizing the binding position of sheet bundles, especially when handling small and large-sized sheets, and require manual insertion which can be cumbersome and inefficient.
Innovation Solution
A post-processing apparatus incorporating a sheet bundle inserter, a movable sheet stacker, and a sheet binder, which allows for the insertion and withdrawal of the movable sheet stacker, enabling easy handling of sheets of various sizes and facilitating efficient binding operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a retractable support is disposed on the sheet bundle inserter to support the end face of the sheet bundle, then the binding position stability is improved, but the device complexity increases
Solution Approach 1:
The support member is configured to be movable between a support position and a retracted position. When moved to the support position, it stabilizes the sheet bundle during binding; when retracted, it clears the binding area. This dynamic adjustment allows the same component to serve multiple functions, reducing overall device complexity while maintaining binding position stability.
2Device complexity
If manual insertion of sheet bundles is required, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The support member automatically moves to the support position when the sheet bundle is inserted and returns to the retracted position after binding. This automatic operation eliminates the need for manual intervention to adjust the support, improving ease of operation while keeping the device structure relatively simple.
3Device complexity
If the sheet bundle inserter has a fixed structure, then the device complexity is reduced, but the adaptability deteriorates
Solution Approach 1:
The movable support member enables the sheet bundle inserter to adapt to different sheet bundle sizes and types. By adjusting the support position and height, the device can accommodate various binding requirements without requiring multiple fixed structures, thus improving adaptability while maintaining relatively simple device complexity.

AI summary
A post-processing apparatus including a sheet bundle inserter, a movable sheet stacker, and a sheet binder. The sheet bundle inserter inserts a sheet bundle having multiple sheets overlapped on each other. The movable sheet stacker is inserted into and withdrawn from the sheet bundle inserter. The movable sheet stacker has a stacker face on which the sheet bundle is stacked. The sheet binder is in the sheet bundle inserter, and performs a sheet binding operation on the sheet bundle stacked on the movable sheet stacker.
