Cover Positioning in Wrap-Bookbinding Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming systems struggle with wrap-bookbinding when the size of the book body and cover differ, leading to misalignment and loss of image parts during the bookbinding process.
Innovation Solution
An image forming system that includes a relative-position information input section, storage section, and control section to adjust the relative position between the cover and body sheets, ensuring accurate alignment and proper positioning for high-quality bookbinding across various wrap-bookbinding scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a cover in a size that accords with the size of the body is fed, then the bookbinding process is simple, but the system cannot handle cases where the size of a body and that of the cover are different
Solution Approach 1:
The system dynamically adjusts the cover positioning based on the actual size relationship between the cover and body. The relative position control section modifies the cover's position during the bookbinding process according to stored relative position information, enabling the system to adapt to various size combinations without requiring complex hardware changes.
Solution Approach 2:
The system changes the positioning parameters of the cover based on the size relationship between cover and body. By storing relative position information and using this data to control the cover's position, the system adjusts key parameters (position, alignment) to handle different size combinations while maintaining a relatively simple overall structure.
2Manufacturing precision
If the cover is stopped at a predetermined position, then the alignment is simple, but misalignment occurs when the cover and body sizes differ
Solution Approach 1:
The system performs preliminary actions by storing relative position information before the actual bookbinding process. This pre-stored information guides the relative position control section to automatically adjust the cover position, eliminating the need for manual intervention and ensuring precise alignment even when sizes differ.
Solution Approach 2:
The system uses feedback from the stored relative position information to control the cover positioning. The relative position control section references the pre-stored data and adjusts the cover position accordingly, creating a feedback loop that ensures accurate alignment without requiring complex real-time measurement systems.
3Manufacturing precision
If the edges of the cover are aligned with the edge of the body, then the bookbinding is straightforward, but image parts are lost when cover and body sizes differ
Solution Approach 1:
The system dynamically adjusts the cover positioning to prevent image loss. By modifying the cover's position during the bookbinding process based on stored relative position information, the system ensures that images on the cover and body remain properly aligned and neither part is lost, even when the cover and body have different sizes.
Solution Approach 2:
The system changes the positioning parameters of the cover to prevent image loss. By adjusting the cover's position according to the size relationship with the body and using this information to control the alignment, the system preserves complete images on both cover and body while maintaining manufacturing precision.

AI summary
An image forming system forms an image on body sheets and wraps, in a square shape, a stack of the body sheets having the image formed thereon with a cover to bind a book. The image forming system includes a relative-position related information input section for input of information related to a relative position between the cover and the stack of the body sheets; a storage section for storing the information related to the relative position, corresponding to a job; and a relative position control section for control of the relative position between the cover and the stack of the body sheets, based on the information related to the relative position stored in the storage section.
