Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roll packaging apparatuses struggle with accurately wrapping protective sheets around product rolls without exposing the paper surface, maintaining surface quality, and minimizing dust contamination due to abrasive friction, while also requiring multiple costly units for high throughput.
Innovation Solution
A product roll packaging apparatus with a buffer conveyor, transfer unit, wrapping unit, and protective sheet supply system, featuring a position correcting mechanism and edge position control to align the roll and sheet accurately, and a tape supply unit for adhesive application, allowing for precise wrapping and minimizing friction-induced dust.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the packaging sheet is guided by a feeder guide to insert the leading end into the gap, then the packaging process can be automated, but the packaging sheet produces paper dust that contaminates the roll of paper
Solution Approach 1:
The patent removes the feeder guide from the system entirely. Instead of guiding the packaging sheet through a feeder guide that causes friction and dust, the sheet is fed directly into the wrapping position where it is immediately wrapped around the roll, eliminating the source of dust contamination while preserving automation.
Solution Approach 2:
The patent introduces a sheet feeding mechanism that uses suction or gravity-fed pathways without physical contact guides. The packaging sheet is transported through an intermediary pathway that minimizes friction and prevents paper dust generation, then positioned for wrapping without abrasive contact.
2Manufacturing precision
If the clearance between the packaging sheet and feeder guide is reduced to increase positioning accuracy, then the widthwise positioning improves, but the packaging sheet produces more paper dust due to abrasive friction
Solution Approach 1:
The feeder guide causing friction is completely removed from the system. The patent uses an alternative sheet feeding approach where the packaging sheet is transported without contact guides, eliminating the trade-off between positioning accuracy and dust generation.
Solution Approach 2:
The patent replaces the mechanical feeder guide system with a non-contact or minimal-contact feeding mechanism, possibly using air suspension, gravity feeding, or precision positioning without physical guides, thereby eliminating friction-induced dust while maintaining positioning accuracy.
3Productivity
If multiple packaging units are used to achieve high throughput, then productivity increases, but the cost and space requirements increase
Solution Approach 1:
The patent employs a dynamic sheet feeding system that can adjust speed and positioning to match the wrapping cycle, allowing a single unit to operate at high throughput. The system uses variable speed conveyors and real-time positioning to maintain high productivity without requiring multiple static packaging units.
Solution Approach 2:
The patent implements a continuous wrapping process where the packaging sheet is fed continuously without interruption, and the roll is wrapped in a seamless operation. This continuous action maximizes productivity of a single unit by eliminating idle time and sequential operations that would require multiple units.

AI summary
A product roll packaging apparatus includes a transfer unit for lifting and transferring a product roll from a conveyor, a wrapping unit for wrapping a protective sheet around the roll and attaching an end thereof with an adhesive tape, a protective sheet supply unit for cutting off the sheet from a sheet roll and supplying it along a protective sheet path line to the wrapping unit, and a tape supply unit for supplying the tape to the end of the cut sheet. The transfer unit includes a position correcting mechanism for establishing a reference line depending on the roll size, and bringing a reference end face of the roll into alignment with a vertical plane including the reference line. The protective sheet supply unit includes an edge position control mechanism for bringing a reference edge of the sheet into alignment with the reference line corresponding to the roll size.
