Bag Feeding Device with Position Correction for Warpage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag feeding devices struggle to efficiently handle and feed various types of packaging bags, such as zip-fastener bags, gusset bags, and large-sized bags, due to warpage issues when stacked, requiring complex placement methods and often necessitating separate feeding systems, which burdens workers.
Innovation Solution
A bag feeding device comprising a conveyor system with a capture unit, placement section, and supply unit, featuring adjustable conveyor width and position correction mechanisms, allowing for sequential and accurate feeding of diverse bag types without the need for precise placement, enabling rough placement of bags and ensuring proper alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If packaging bags are stacked one upon another in a magazine, then feeding efficiency is improved, but the bags cause warpage due to bulky upper parts and ends
Solution Approach 1:
The invention divides the bag feeding process into two independent systems: a conveyor system for bags with bulky upper parts (zip-fastener bags) and a magazine system for bags without such bulks (flat bags, sacks). This segmentation allows each system to be optimized for its specific bag type, preventing warpage while maintaining feeding efficiency.
Solution Approach 2:
The invention creates a universal bag feeding device that can handle multiple bag types through a single integrated structure. The device includes a common magazine that can accommodate different bag types and a conveyor system that can process various bag configurations, eliminating the need for separate feeding systems for different bag types.
2Reliability
If a conveyor system is used to feed bags separated like sashimi, then bag warpage is prevented, but the placement work becomes complicated and burdensome
Solution Approach 1:
The invention performs preliminary action by having workers place bags in a relaxed manner on the conveyor, without requiring precise separation or alignment. The position correction mechanism then performs the precise alignment in advance before the bags reach the feeding point, eliminating the burden of precise placement while maintaining reliable bag alignment.
3Manufacturing precision
If separate bag feeding systems are provided for different bag types, then feeding accuracy is improved, but device complexity increases
Solution Approach 1:
The invention merges the conveyor system and magazine system into a single integrated bag feeding device. The common magazine can hold different bag types, and the conveyor system can process various bag configurations through position correction mechanisms. This merging maintains feeding accuracy for different bag types while reducing device complexity by eliminating the need for completely separate feeding systems.

AI summary
A bag feeding device includes a bag feed conveyor, a bag capture unit, a bag placement section and a bag supply unit. The bag feed conveyor is configured to sequentially convey packaging bags. The bag capture unit is configured to capture the sequentially conveyed packaging bags one by one. The packaging bags captured by the bag capture unit are placed on the bag placement section one by one. The bag placement section is provided with a bag position correction unit. The bag supply unit is configured to hold the packaging bag placed on the bag placement section to supply the packaging bag to a bag holding unit of a packaging machine.
