Bookbinding Device Guide Member Adjusts Print Medium Drop Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bookbinding devices face issues with sequence upset when stacking multiple print media of varying sizes, leading to potential misalignment and incorrect binding.
Innovation Solution
A bookbinding device with a guide plate and stack plate system, including a guide member that adjusts the drop position of print media based on size, supported by pulleys and belts, and a lifting mechanism to manage the stacking order and prevent sequence disruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If print media of varying sizes are stacked for bookbinding, then the device can handle diverse print media, but sequence upset occurs leading to misalignment and incorrect binding
Solution Approach 1:
The guide member is made movable rather than fixed, allowing it to dynamically adjust its position according to the size of each print medium. This enables the system to adapt to varying print media sizes while maintaining proper alignment, as the guide member can be repositioned to accommodate different widths and lengths without causing sequence upset
Solution Approach 2:
The system changes the positional parameter of the guide member to match the dimensions of different print media. By adjusting the guide member's position along the guide plate, the system maintains optimal alignment parameters for each size of print medium, preventing misalignment and binding errors while handling diverse sizes
2Manufacturing precision
If a guide member is added to adjust drop position, then alignment precision improves, but device complexity increases
Solution Approach 1:
The guide member acts as an intermediary element between the guide plate and the print medium. It mediates the alignment process by providing a controllable interface that adjusts the drop position of print media, achieving precise alignment without requiring complex modifications to the entire bookbinding system
Solution Approach 2:
The alignment function is segmented into a separate, movable guide member that can be independently adjusted. This segmentation allows the alignment mechanism to be simplified and isolated from the main bookbinding structure, reducing overall system complexity while maintaining high alignment precision

AI summary
A bookbinding device and a print-medium post-treatment apparatus having the same. In the bookbinding device, when a print medium drops and is loaded a stack plate, a drop position of a leading end of the print medium is changed according to a size of the print medium. This prevents sequence upset of print media when the print media are stacked one above another on the stack plate.
