Saddle-Stitch Binding Collator Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional saddle-stitch book binding systems require separate configurations for different printing methods, leading to high costs and space occupation due to the need for dedicated systems for each method.
Innovation Solution
A versatile saddle-stitch book binding system that incorporates a collator capable of switching between operating modes, allowing it to function as either a collator or an additional sheet supplying device, combined with a cut paper supplying device, folding device, or cutter, and a saddle stitching device, enabling handling of various printed materials from different printing methods with a single system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated saddle-stitch book binding system is provided for each printing method, then the system can handle specific printed material effectively, but the manufacturing cost and installation space increase significantly
Solution Approach 1:
The collator is designed to perform multiple functions: it can operate as a traditional collator for offset printing, as a cut paper supplying device for cut paper digital printing, and as a folding device for roll paper digital printing. This multi-functionality allows a single saddle-stitch book binding system to handle different printing methods without requiring separate dedicated systems for each method.
Solution Approach 2:
The system incorporates a controller that dynamically switches the operating mode of the collator based on the type of printed material being processed. The collator can transition between non-operating mode, first operating mode (as collator), and second operating mode (as additional sheet supplying device), enabling adaptive handling of different printing methods within a single system.
2Manufacturing precision
If multiple dedicated systems are provided for different printing methods, then each system can be optimized for its specific function, but the total installation space and device complexity increase
Solution Approach 1:
The patent merges the functions of multiple dedicated systems (collator, cut paper supplying device, folding device) into a single collator unit. By integrating these previously separate devices into one multi-functional component, the system reduces the total number of devices required while maintaining the specialized capabilities needed for different printing methods.
3Adaptability or versatility
If a single versatile system is used for all printing methods, then the manufacturing cost and space are reduced, but the system complexity and configuration flexibility requirements increase
Solution Approach 1:
The controller receives information about the type of printed material to be processed and automatically configures the collator to the appropriate operating mode. This feedback mechanism allows the system to adapt its configuration based on the specific printing method being used, simplifying the user interface while maintaining the complexity needed for handling multiple printing methods.

AI summary
This system is provided with: a conveying device 1 that conveys paper P along a conveying path F; a sheet paper supply device 2, paper-folding device, or cutter connected to an upstream end of the conveying path; a gathering device 3 disposed midway through the conveying path; a saddle stitch device 7 connected to a downstream end of the conveying path; and a management unit 13 that collectively controls the conveying device, the sheet paper supply device, the paper-folding device, the cutter, the gathering device, and the saddle stitch device. The gathering device can switch operation between a non-operating mode, a first operating mode for operating as a primary gathering device, and a second operating mode for operating as a paper insertion device.
