Rebar Binding Machine Feed Layout for Easier Wire Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing reinforcing bar binding machines require space for displacement members and operation members between the feeding member and the magazine, hindering the arrangement of the housing unit and causing wire loading issues.
Innovation Solution
The binding machine incorporates a housing unit that houses the wire in a drawable manner, with a feeding unit that includes a pair of feeding members and a displacement unit that displaces in a direction intersecting the wire feeding direction, eliminating the need for space between the housing and feeding member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If displacement members and operation members are provided between the feeding member and the magazine, then the feeding members can be displaced to contact and separate, but the magazine cannot be freely disposed and wire loading is hindered
Solution Approach 1:
The patent changes the displacement direction from the conventional direction (between feeding member and magazine) to a direction intersecting with the wire feeding direction. This dimensional change allows the displacement members to be positioned without obstructing the wire feed path and without constraining magazine arrangement, thereby resolving the spatial conflict.
Solution Approach 2:
The patent separates the displacement function from the wire feed path by providing displacement members that operate in a direction intersecting with the wire feeding direction. This segmentation allows independent operation of displacement and wire feeding functions without mutual interference.
2Ease of operation
If displacement members and operation members are provided between the feeding member and the magazine, then the feeding members can be displaced to contact and separate, but the device size increases
Solution Approach 1:
By changing the displacement direction to intersect with the wire feeding direction, the patent utilizes previously unused spatial dimensions, allowing compact arrangement of components without increasing overall device volume.
Solution Approach 2:
The patent merges the displacement mechanism with the existing feeding member structure, eliminating the need for separate displacement members and operation members in the conventional position, thereby reducing overall device size.
3Ease of operation
If displacement members and operation members are provided between the feeding member and the magazine, then the feeding members can be displaced to contact and separate, but the wire loading path is obstructed
Solution Approach 1:
The patent positions displacement members to operate in a direction intersecting with the wire feeding direction, which creates a clear wire loading path without obstruction from displacement or operation members, thereby facilitating easy wire loading.

AI summary
A reinforcing bar binding machine (1A) includes a magazine (2A) in which a wire (W) is housed, a curl guide unit (5A) that winds the wire (W) around a reinforcing bar(S), a wire feeding unit (3A) that feeds the wire (W), and a binding unit (7A) that twists crossing portions between one end and the other end of the wire (W) wound around the reinforcing bar(S). The wire feeding unit (3A) is configured such that a second displacement member (36) for displacing a second feed gear (30R) is located behind the second feed gear (30R) and provided between the second feed gear (30R) and a handle portion (11A).
