Slanting Surface Guide for Sheet Conveyance Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet conveyance systems face challenges in securely discharging cut trash of varying lengths, widths, and thicknesses into a trash box, especially when the cut trash does not fall into a prone position on the conveyance belt, leading to potential jamming and increased drive load.
Innovation Solution
A sheet conveyance apparatus with a slanting surface that forms a narrowing space in the vertical direction, ensuring the cut trash is guided and pinched by a conveyance belt and driven belt system, allowing for stable and secure discharge into a trash box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional conveyance belt system is used to discharge cut trash, then the system structure is simple, but the cut trash may be erected on the belt and cause jamming or increased drive load
Solution Approach 1:
The patent introduces a slanting surface that forms a narrowing space in the vertical dimension, guiding the cut trash from a horizontal fall position into a vertical conveyance path. This dimensional transition ensures the cut trash is properly oriented before entering the pinch conveyance system, preventing erection and jamming while maintaining system reliability.
Solution Approach 2:
The slanting surface acts as an intermediary element between the cut trash fall position and the conveyance belt system. It guides and orients the cut trash before it enters the conveyance mechanism, ensuring proper positioning without requiring complex adjustment mechanisms or increasing overall system complexity.
2Adaptability or versatility
If the trash box is positioned away from the cutting position, then the layout flexibility is improved, but the cut trash cannot fall directly into the trash box and requires additional conveyance mechanisms
Solution Approach 1:
The slanting surface creates a vertical narrowing space that guides cut trash from various horizontal positions into a unified vertical conveyance path. This allows the trash box to be positioned away from the cutting position while maintaining a simple conveyance structure, as the slanting surface pre-positions all cut trash regardless of where it fell.
Solution Approach 2:
The slanting surface serves multiple functions: it guides cut trash from different horizontal positions, orients the cut trash properly, and funnels everything into a single conveyance path. This multi-functionality allows layout flexibility without requiring separate conveyance mechanisms for different trash positions.
3Productivity
If cut trash with large width and curl is conveyed, then the conveyance capacity is improved, but the cut trash may be pinched in an undesirable position causing excessive drive load
Solution Approach 1:
The slanting surface performs preliminary action by guiding and orienting the cut trash before it enters the pinch conveyance system. This pre-positioning ensures that even wide and curled cut trash enters the pinch point in a controlled manner, preventing undesirable pinching positions and reducing the drive load required for conveyance.
Solution Approach 2:
The slanting surface acts as an intermediary that mediates between the varied states of cut trash (different widths, curls, positions) and the pinch conveyance system. It standardizes the input to the conveyance mechanism, ensuring consistent orientation and position that prevents excessive drive load while maintaining conveyance capacity for various trash types.
