Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing bag supply systems require manual intervention for conveying and transferring bag bundles, which poses safety and hygiene risks and inefficiencies, especially when handling large numbers of bags, and require synchronized timing to avoid container box interference.
Innovation Solution
A bag supply system comprising a bag making machine, a bag bundle positioning device, a bag bundle delivery device, a bag bundle conveyance device with a movable support part, a bag bundle takeoff device, and a bag supply device, where bag bundles are conveyed along an endless track between delivery and supply zones, allowing automated transfer and stacking of container boxes to facilitate efficient bag distribution without human intervention.

Engineering Contradiction Analysis
1Extent of automation
If manual intervention is used for conveying and transferring bag bundles, then flexibility and simplicity are maintained, but safety risks and hygiene issues arise
Solution Approach 1:
The patent introduces a container box as an intermediary carrier between the bag making machine and the packaging machine. This container box serves as a buffer and transport medium, allowing automated handling without direct manual intervention on the bag bundles themselves. The container box absorbs the complexity of coordination while keeping the bag handling simple.
Solution Approach 2:
The system enables self-service automation where the container box automatically receives bag bundles from the bag making machine, transports them along the endless track, and delivers them to the packaging machine. The movable support part automatically adjusts to accommodate container boxes, eliminating the need for manual positioning and transfer operations.
2Quantity of substance
If multiple container boxes are used for conveying large numbers of bags, then capacity is increased, but synchronized timing is required to avoid interference
Solution Approach 1:
The patent resolves the timing coordination problem by transitioning from linear sequential transport to multi-dimensional concurrent transport. Multiple container boxes operate simultaneously on different segments of the endless track, with the movable support part enabling vertical dimension utilization. This allows multiple boxes to be in different phases of the transport cycle without interfering with each other.
Solution Approach 2:
The movable support part provides dynamic adaptability to the system. It can automatically adjust its position and configuration to accommodate multiple container boxes at different locations along the track. This dynamic capability allows the system to handle varying quantities of bags without requiring rigid synchronized timing, as each container box can be serviced independently.
3Reliability
If automated conveyance system is implemented, then manual handling risks are reduced, but system complexity increases
Solution Approach 1:
The patent segments the automated conveyance system into distinct functional modules: the container box for holding bags, the endless track for transport, and the movable support part for positioning. This segmentation allows each component to be independently designed, controlled, and maintained, reducing overall system complexity while maintaining automation benefits. The container box acts as an isolated unit that can be handled independently.
