Scoring Machine Roller Positioning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scoring machines for buckle-type sheet folding apparatuses have a complex structure and large size due to the need for separate positioning mechanisms for upper and lower rollers, making them cumbersome and difficult to set up quickly and precisely.
Innovation Solution
A simplified scoring machine design with a single positioning unit and reduced mechanism size, incorporating a frame with parallel rotary shafts, paired rollers with stop screws, a slide guide, and a control unit that allows for easy and rapid positioning of rollers using a rotatable member and torsion springs, enabling synchronization and precise alignment of convex and concave rollers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate positioning mechanisms are used for upper and lower rollers, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The patent combines the positioning mechanisms for upper and lower rollers into a single integrated positioning unit. This unit simultaneously positions both rollers through a unified structure, eliminating the need for separate positioning mechanisms while maintaining positioning precision through the coordinated design of the positioning elements.
Solution Approach 2:
The positioning unit is designed to perform multiple functions: it positions both upper and lower rollers, provides alignment reference through the slide guide, and enables synchronized adjustment. This multi-functional design reduces the overall number of components while achieving the required positioning precision for both rollers.
2Measurement precision
If multiple positioning mechanisms are used, then positioning precision is improved, but the size of the scoring machine increases
Solution Approach 1:
By merging the positioning functions for upper and lower rollers into a single positioning unit, the patent significantly reduces the spatial requirements. The integrated design allows both positioning functions to share common structural elements, thereby reducing the overall volume of the scoring machine while maintaining positioning precision.
3Measurement precision
If a complex positioning mechanism is used, then positioning precision is improved, but ease of operation deteriorates
Solution Approach 1:
The integrated positioning unit simplifies operation by providing a single, unified interface for positioning both rollers. Operators need to interact with only one positioning mechanism rather than coordinating multiple separate mechanisms, making the operation more intuitive and easier to perform while maintaining precision through the designed positioning features.
4Volume of moving object
If the scoring machine is made compact, then ease of integration is improved, but positioning precision may deteriorate
Solution Approach 1:
The patent employs a slide guide mechanism that provides precise linear guidance within a compact structure. The slide guide enables accurate positioning movement in a space-efficient manner, allowing the scoring machine to maintain small dimensions while achieving the required positioning precision through the guided motion system.
Solution Approach 2:
The positioning system utilizes precise dimensional relationships and geometric constraints in the positioning unit design. By carefully designing the spatial arrangement of positioning elements and utilizing dimensional tolerances, the patent achieves accurate roller positioning within a compact machine footprint.

AI summary
A scoring machine incorporated in a sheet folding apparatus forms scores on sheets according to a folding pattern. The scoring machine comprises upper and lower rotary shafts provided with pairs of convex and concave rollers, and a positioning unit slidably attached to a slide guide. When a rotatable member is arranged at a standing position, the convex roller engages with a groove on one end face of the rotatable member, or the concave roller engages with a projection on the other end face of the rotatable member. A sequence pattern of the pairs of convex and concave rollers on the upper and lower rotary shafts corresponding to the folding pattern is displayed on a display. The positioning unit stops at the specified positions of the pairs of convex and concave rollers while sliding.
