Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet processing machine feeders with blowing devices face challenges in adjusting the lateral position of blowing devices to accommodate changes in sheet format without manual intervention, leading to potential collisions with other components and increased complexity.
Innovation Solution
The blowing device is mounted with a movement component transverse to the transport direction, forcibly coupled with the adjustment movement in the transport direction, allowing for automatic adjustment of the lateral position in conjunction with side stops, reducing the risk of collisions and simplifying the mechanical design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lateral position of the blowing device is made adjustable to accommodate changing sheet formats, then the adaptability of the feeder is improved, but the device complexity increases due to additional adjustment mechanisms
Solution Approach 1:
The patent combines the lateral positioning function of the blowing device with the side stop positioning system. Both components are adjusted together as a unified mechanism, eliminating the need for separate adjustment systems and reducing overall device complexity while maintaining adaptability to different sheet formats
Solution Approach 2:
The side stop adjustment mechanism serves dual purposes: it positions the side stop itself and simultaneously positions the blowing device laterally. This multi-functional approach reduces the number of independent adjustment mechanisms needed in the system
2Ease of operation
If the blowing device is made movable in the transport direction to optimize sheet separation, then the ease of operation is improved, but the risk of collision with other components increases
Solution Approach 1:
The system performs preliminary positioning of the blowing device in the transport direction by coupling it to the side stop adjustment. This pre-positioning ensures the blowing device is correctly located before sheet processing begins, reducing the risk of collision during operation
Solution Approach 2:
The coupled adjustment mechanism provides positional feedback between the side stop and blowing device. As the side stop is adjusted to a new position, the blowing device automatically follows with a corresponding position change, ensuring coordinated movement and preventing collisions
3Productivity
If manual adjustment of the blowing device is replaced with automatic adjustment, then the productivity is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The system uses itself to perform the positioning function. The side stop adjustment mechanism automatically positions the blowing device through mechanical coupling, eliminating the need for external actuators or complex control systems. This self-service approach achieves both high speed and precision through purely mechanical means
