Box Packaging Pushing Mechanism With Bag-Deforming Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pushing mechanisms for bags into laterally open boxes can cause posture disorder due to protrusion and interference with peripheral components, leading to potential rotation or disorder of the bags inside the box.
Innovation Solution
A pushing mechanism with a contact portion that bends one side of the bag in the pushing direction, using a contact portion that protrudes to deform the bag and suppress posture disorder, and a raising and lowering unit to adjust bag placement, along with an expandable and contractible contact portion to manage bag interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a pushing mechanism is used to push bags into a box, then the bags can be efficiently packaged, but the bags may protrude from the box and interfere with peripheral components, causing posture disorder
Solution Approach 1:
The pushing plate is designed with a contact portion that has a different shape and size from other portions, creating local structural variation. This contact portion specifically engages with the bag to control its posture during pushing, while other portions maintain general pushing function, thus resolving the contradiction between efficient packaging and posture stability
Solution Approach 2:
The contact portion is designed in advance with specific geometric features (protrusion height between 1/10 to 1/3 of bag length) that pre-determine the bag's deformation and posture control during the pushing process. This preliminary structural design ensures the bag maintains proper posture before it enters the box, preventing interference with peripheral components
2Device complexity
If the bag is pushed straight into the box without deformation, then the pushing process is simple, but the bag may rotate or change posture inside the box when interfering with peripheral components
Solution Approach 1:
Rather than making the entire pushing mechanism complex, only a local contact portion on the pushing plate is designed with special geometry. This localized complexity is sufficient to control bag posture while keeping the rest of the pushing mechanism simple and straightforward
Solution Approach 2:
The contact portion is designed with asymmetric or non-uniform geometry that creates controlled asymmetric deformation of the bag during pushing. This asymmetric design allows the bag to be guided into the correct posture, preventing rotation and maintaining stability during the pushing process

AI summary
A pushing mechanism pushes a plurality of bags into a laterally open box in an erected posture. The pushing mechanism includes a box standby unit for causing the box to stand by, an article placement unit having a placement surface on which the plurality of bags are temporarily placed in the erected posture, and a pushing unit extending in an alignment direction of the plurality of bags and pushing the plurality of bags placed on the placement surface into the box by moving toward an opening of the box from the article placement unit. The pushing unit has a contact portion that comes into contact with a portion of the bag in a height direction in the erected posture such that one side of the bag is bent in a pushing direction.
