Outer Bag Structure for Automated Feeding of Overlapped Product Bags
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag making, boxing, and bag feeding processes require significant manual labor, are prone to errors, and lack automation, leading to inefficiencies and increased costs, particularly in transitioning from bag making to filling machines.
Innovation Solution
A product-containing outer bag design that integrates multiple bags with a resin film base material, featuring adhesive seals, thick portions, and fitting tools, along with a bag feeding device that supports, opens, aligns, and supplies the bags to a filling machine, enabling automated handling from bag making to filling without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual bag making, boxing, and bag feeding processes are used, then flexibility and adaptability are maintained, but labor intensity increases and automation is reduced
Solution Approach 1:
The outer bag is divided into multiple sealed compartments, each containing individual bags or groups of bags. This segmentation allows automated feeding devices to access and supply bags from different compartments independently, enabling automation while maintaining process flexibility.
Solution Approach 2:
Bags are pre-packaged in outer bags with fitted tools that maintain their shape and position. The outer bags are prepared in advance with bags arranged in specific orientations, allowing automated devices to directly pick and supply bags without manual intervention during the feeding process.
2Reliability
If bags are stacked loosely for easy access, then ease of operation improves, but positioning accuracy and supply reliability deteriorate
Solution Approach 1:
Different regions of the outer bag structure serve different functions: the fitted tool provides rigid support and positioning accuracy, while the sealed compartments provide organized storage. This local differentiation allows the system to achieve both positioning reliability and operational ease simultaneously.
Solution Approach 2:
The outer bag acts as an intermediary structure between bag storage and the filling machine. It maintains bags in a ready-to-use state with proper positioning, while the fitted tool serves as a mediator that enables automated devices to interact with the bags without direct manual handling.
3Volume of moving object
If multiple bags are bundled together, then space efficiency improves, but device complexity and error prevention requirements increase
Solution Approach 1:
Individual bags are nested within the outer bag structure, with each bag contained in a sealed compartment. This nesting arrangement maximizes space efficiency during transportation and storage, while the compartmentalized structure simplifies the feeding device by providing clear access points to individual bags without requiring complex unbundling mechanisms.

AI summary
A product-containing outer bag in which a plurality of bags stacked in a row continuously or intermittently, with the bags, as products, partially overlapping each other, are wrapped and integrated with an outer bag, for outer packaging, having a resin film as a base material such that a state of stacking of the bags is maintained, in which the outer bag includes a first side, a second side opposite to the first side, an adhesive seal, and a thick portion disposed along an edge of the first side, and an auxiliary seal is disposed on a region (S) adjacent to a portion, of the adhesive seal, at a predetermined interval from an edge of the second side.
