Cosmetic Pad Pouch Packaging With Adaptive Guide Rollers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging devices for individual pouch-packaged pad-type cosmetic products face challenges in consistently supplying cosmetic cotton fabric by a preset length, accurately aligning pouches on a transport conveyor, and handling variable thicknesses, leading to inefficiencies and hygiene issues.
Innovation Solution
A packaging device with a first guide roller connected to a second guide roller through a rotational interlock device, where the second guide roller is fixed and the first is pressurized by an elastic pressure member, ensures consistent supply of cosmetic cotton fabric by a predetermined length, while a rotation suction part aligns pouches correctly on the conveyor, and uses elastic pressure members to adjust for thickness variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a packaging device uses guide rollers to supply cosmetic cotton fabric, then the fabric can be supplied continuously, but the fabric length precision and consistency deteriorate due to difficulty in controlling the supply length accurately
Solution Approach 1:
The guide roller system employs dynamic elements including a movable guide roller that can adjust its position, and an elastic pressure member that provides variable pressure based on fabric thickness. This dynamic configuration allows the system to adapt to different fabric conditions while maintaining precise length control, resolving the contradiction between precision and complexity.
Solution Approach 2:
The system changes physical parameters such as the pressure applied by the elastic pressure member and the position of the movable guide roller to optimize fabric supply. By adjusting these parameters based on fabric thickness and tension, the system achieves precise length control without requiring overly complex mechanisms.
2Adaptability or versatility
If the packaging device handles variable thickness cosmetic cotton fabric, then the adaptability improves, but the supply stability and length consistency deteriorate
Solution Approach 1:
The elastic pressure member provides dynamic pressure adjustment based on fabric thickness variations. When fabric thickness changes, the elastic element automatically adjusts the gripping force, maintaining stable supply without compromising reliability. The movable guide roller also adjusts its position dynamically to accommodate thickness variations.
Solution Approach 2:
The system changes the pressure parameter applied to the fabric based on its thickness. The elastic pressure member converts thickness variations into corresponding pressure adjustments, allowing the system to handle variable thickness while maintaining consistent supply stability and length control.
3Productivity
If the packaging device aligns pouches on transport conveyor, then the packaging efficiency improves, but the time for alignment and positioning increases
Solution Approach 1:
The rotation suction part performs preliminary alignment actions by suctioning and rotating pouches into correct positions before they reach the main packaging area. This preliminary positioning reduces the time needed for final alignment and improves overall packaging efficiency without significant time loss.
Solution Approach 2:
The suction-based alignment mechanism uses pneumatic forces to quickly grasp and rotate pouches into correct positions. This pneumatic system enables rapid alignment operations that improve packaging efficiency while minimizing the time required for positioning, as the suction and rotation actions can be performed quickly and continuously.

AI summary
A packaging device for an individual pouch-packaged pad-type cosmetic product is proposed. First and second guide rollers gripping a longitudinally cut cosmetic cotton fabric from opposite sides and supply it at a constant speed are connected to each other through a second rotational interlock device to be rotated equally, so that the cosmetic cotton fabric can be supplied constant by a preset length. Among the first and second guide rollers, the second guide roller is fixed but the first guide roller is moved with pressure of a second elastic pressure member, so that the cosmetic cotton fabric can be stably supplied by a predetermined length while variably responding to the thickness thereof. A rotation suction part sucks cut pouches and then is rotated to place and align the pouches in correct positions on a transport conveyor, so that the final produced pouches are aligned to reduce a packaging time.
