Sheet Bundle Conveyance Posture Correction for Bookmaking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bookmaking systems face precision issues during the conveyance of sheet bundles, leading to skewing or misalignment due to rattling components in the conveyance mechanism, resulting in inaccurate adhesive application and binding.
Innovation Solution
A sheet conveyance apparatus with posture correction means, utilizing a gripping conveyance system comprising first and second clamping members that align and rotate the sheet bundle to a reference member, ensuring accurate positioning and alignment during the conveyance process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a gripping conveyance mechanism is used to transport the sheet bundle, then the sheet bundle can be conveyed from the tray to the finishing position, but the sheet bundle becomes skewed or misaligned due to rattling components and backlash in the mechanism
Solution Approach 1:
The patent applies preliminary action by providing a posture correction means that corrects the sheet bundle posture before it reaches the finishing position. The correction means includes a correction member that contacts the sheet bundle and aligns it in the conveyance direction, preventing misalignment issues before they affect the finishing process
Solution Approach 2:
The patent uses an intermediary approach by introducing a posture correction means as a mediator between the gripping conveyance mechanism and the finishing position. This correction means includes a correction member that acts as an intermediate element to adjust and maintain the sheet bundle alignment during conveyance
2Ease of operation
If rack and pinion or belt drive mechanisms are used to guide the gripping means, then the gripping means can be driven to engage the guide rail, but backlash and belt movement cause loss of positioning precision
Solution Approach 1:
The patent applies feedback by providing a posture correction means that continuously monitors and adjusts the sheet bundle alignment during conveyance. The correction means detects posture deviations and applies corrective forces to maintain proper alignment, compensating for positioning errors introduced by the drive mechanism

AI summary
A sheet conveyance apparatus conveys a posture corrected sheet bundle to a correct position, and includes a discharge path for conveying out a sheet, a tray device for stacking sheets conveyed from the discharge path in a bundle shape, and a gripping conveyance device for conveying the sheet bundle on the tray device to a predetermined finishing position. A finishing device finishes the sheet bundle gripped by the gripping device.
