Wire Binding Machine with Movable Function Unit to Prevent Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In reinforced bar binding machines, the movement of retreat mechanisms and returning parts onto the wire feeding locus can cause wire deviation, jamming, and buckling, as they collide with the wire, leading to operational issues.
Innovation Solution
A binding machine design where a function unit, such as a regulation member and retreat mechanism, is positioned to deviate from the wire feeding locus in a predetermined state, preventing collisions and allowing easy removal of the wire by moving to a second position when issues occur.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the retreat mechanism and returning part move onto the feeding locus of the wire, then the binding operation can be performed, but the wire may collide with these components causing deviation, jamming, or buckling
Solution Approach 1:
The function unit is designed to be movable between a first position on the feeding locus and a second position deviating from the feeding locus. During wire feeding, the function unit is positioned at the second position to avoid collision. During binding operation, it moves to the first position to perform its function. This dynamic positioning resolves the contradiction by making the system adaptable to different operational phases.
2Productivity
If the function unit is positioned on the feeding locus during binding operation, then binding can be performed, but wire removal becomes difficult when jamming or deviation occurs
Solution Approach 1:
The function unit's movable design allows it to be positioned at the second position (deviating from feeding locus) when wire feeding or removal is needed, and at the first position (on feeding locus) when binding operation is required. This dynamic repositioning enables easy wire removal while maintaining binding capability.

AI summary
A binding machine includes: a feeding unit capable of feeding a wire and winding the wire around a to-be-bound object; and a function unit movable between a first position located on a feeding locus of the wire and a second position deviating from a position on the feeding locus of the wire. The function unit is located in the second position in a predetermined state.
