Binding Machine Guide Displacement With Foreign-Object Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reinforcing bar binding machines struggle with foreign objects that inhibit the movement of the guide portion, leading to binding inefficiencies.
Innovation Solution
A binding machine with a guide portion that can move between positions, incorporating a displacement portion driven by a driving mechanism and accumulation/entry suppressing portions to prevent foreign objects from obstructing its movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the guide portion is made movable to improve wire feeding flexibility, then binding adaptability is improved, but foreign objects can enter the moving region causing operational failures
Solution Approach 1:
The patent extracts the harmful factor (foreign objects) from the system by providing a dedicated discharge path that removes foreign objects from the moving region of the guide portion, thereby maintaining both the movability for adaptability and freedom from foreign objects for reliability
Solution Approach 2:
The patent introduces an intermediary structure (the discharge path with inclined surface and opening) that mediates between the moving guide portion and foreign objects, allowing foreign objects to be smoothly directed out of the moving region without interfering with the guide portion's operation
2Adaptability or versatility
If the guide portion moves between positions to accommodate different binding configurations, then binding versatility is improved, but foreign object accumulation in the moving path occurs
Solution Approach 1:
The patent extracts foreign objects from the moving region by providing a discharge path that actively removes them, preventing accumulation while maintaining the guide portion's movement capability for versatile binding configurations
Solution Approach 2:
The patent addresses foreign object accumulation by introducing a new spatial dimension (the discharge path extending in a direction different from the guide portion's movement path), allowing foreign objects to be removed without interfering with the primary binding function
3Object-generated harmful factors
If a partition plate is added to manage wire dust, then wire dust discharge is improved, but foreign objects entering through the guide path cannot be handled
Solution Approach 1:
The patent creates a multi-functional solution where the discharge path serves dual purposes: it discharges wire dust generated during binding operations and simultaneously removes foreign objects that may enter through the guide path, eliminating the need for separate handling mechanisms

AI summary
There is provided a binding machine, including: a wire feeding portion configured to feed a wire; a guide portion constituting a part of a path through which the wire fed by the wire feeding portion is to pass; a displacement portion configured to move the guide portion between a first position constituting the path and a second position retracted from the path; a driving portion configured to drive the displacement portion; and an accumulation suppressing portion configured to suppress a foreign object from accumulating in a region formed along a moving direction of the displacement portion that is configured to move between the first position and the second position.
