Box-Making Device Flap Positioning via Regulating Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional box-making devices often result in positional displacement of flaps during the carton formation process due to the pushing force from folding guides, leading to potential deformation and improper bonding, which affects the carton's appearance and functionality.
Innovation Solution
A box-making device equipped with spacers, flap-folding guides, pushing members, and regulating members, including endless belts with contactable and retraction regions, to ensure precise folding and orientation of flaps, preventing positional displacement and ensuring accurate bonding without deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a folding guide with an inclined side is used to push down the upper flap, then the upper flap can be folded effectively, but the carton may collapse toward the upstream side due to the pushing force
Solution Approach 1:
A redressment body is introduced as an intermediary component between the folding guide and the carton body. This redressment body receives the pushing force from the folding guide and transfers it to the carton body in a controlled manner, preventing direct collapse while enabling effective flap folding. The redressment body acts as a mediator that decouples the harmful collapsing force from the useful folding action.
2Stability of the object's composition
If a redressment body is added to prevent carton collapse, then the carton body is protected from collapsing, but the upper flap may still be deformed due to pushing-down force from the folding guide
Solution Approach 1:
A second intermediary component, the flap support body, is introduced between the folding guide and the upper flap. This flap support body receives the pushing force from the folding guide and distributes it evenly across the flap surface, preventing localized deformation. It ensures that the flap is pushed down uniformly while maintaining its proper position and orientation during the folding process.
3Stability of the object's composition
If the redressment body contacts the body portion of the carton, then the body portion is protected from collapsing, but the upper flap position may be displaced with respect to the body portion
Solution Approach 1:
The flap support body serves as a precise intermediary that maintains the spatial relationship between the upper flap and the carton body. By supporting the flap during the folding process and distributing forces evenly, it ensures that the flap remains properly aligned with the body portion, preventing positional displacement while both components are being manipulated by the folding mechanism.

AI summary
Provided is a box-making device capable of making a carton comprising a body portion, outer flaps, and middle flaps. The box-making device comprises: a conveyance device having a conveyor for conveying the carton and upstream-side spacers; applicators for applying a bonding material to the middle flaps; flap-folding guides for folding the outer flaps at the outer side of the middle flaps; pushing rollers for pushing the outer flaps toward the middle flaps; and regulating members for regulating the posture of the outer flaps in the conveyance direction by coming into contact with the upstream-side end parts of the outer flaps at least at the point when the outer flaps begin to come into contact with the bonding material.
