Rebar Binding Machine Feed Layout for Flexible Magazine Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reinforcing bar binding machines face constraints in arranging a housing unit due to the presence of a displacement member and operation member, which hinders wire loading and requires additional space, and these components obstruct the wire feed path.
Innovation Solution
A binding machine design with a drawable housing unit, a feeding unit that sandwiches and winds wire around a binding object, and a displacement unit that intersects the feeding direction, allowing for improved arrangement flexibility and unobstructed wire loading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a displacement member and operation member are provided between the feeding member and the magazine to enable the pair of feeding members to contact and separate, then the feeding members can properly feed and release the wire, but the magazine cannot be freely disposed and the device size increases
Solution Approach 1:
The patent changes the spatial arrangement by providing the displacement unit in a direction intersecting with the feeding direction (e.g., lateral direction), rather than between the feeding member and magazine in the feeding direction. This dimensional change allows the magazine to be freely disposed while maintaining the wire feeding and release functions.
2Ease of operation
If the displacement member and operation member are provided between the feeding member and the magazine, then the feeding members can contact and separate properly, but the wire loading is hindered due to obstruction in the feed path
Solution Approach 1:
The patent extracts the displacement unit from the feed path area and relocates it to a position in a direction intersecting with the feeding direction. This extraction removes the obstruction from the wire loading path while preserving the contact and separation functionality of the feeding members.
3Reliability
If the displacement member and operation member are provided in the conventional position, then the feeding mechanism works properly, but additional space is required which prevents device downsizing
Solution Approach 1:
By relocating the displacement unit to an intersecting direction (lateral direction) rather than the conventional position in the feeding direction, the patent achieves compact arrangement that reduces overall device volume while maintaining feeding mechanism reliability through the same contact and separation function.

AI summary
It Provids a reinforcing bar binding machine that reduces restrictions on arrangement of a magazine in which a wire is housed. 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 a second feed gear (30L) and provided between the second feed gear (30L) and a handle portion (11A).
