Wire Binding Machine Feed Path Layout for Complex Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing binding machines face issues with wire feeding defects and path wear when the reel accommodation unit is positioned at the rear of the main body, preventing the binding of complex structures and causing machine failures.
Innovation Solution
The binding machine is designed with a reel accommodation unit at the rear, featuring a load reducing part in the feeding path, a buckling prevention part, and a wear prevention part to minimize friction and support the wire during feeding and returning, ensuring smooth operation and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the reel accommodation unit is arranged on the front side of the main body, then the wire feeding path is shortened, but the to-be-bound objects cannot be inserted into the binding machine for complex building structures
Solution Approach 1:
The reel accommodation unit is inverted from the conventional front-side arrangement to a rear-side arrangement. This inversion allows to-be-bound objects to be inserted from the front without interference from the reel accommodation unit, enabling binding of complex structures while maintaining wire feeding capability through the redesigned path
2Adaptability or versatility
If the reel accommodation unit is arranged on the rear side of the main body, then the to-be-bound objects can be inserted for complex building, but wire feeding defects and path wear occur due to increased friction
Solution Approach 1:
A guide part is introduced as an intermediary component in the wire feeding path. This guide part reduces friction between the wire and the feeding path, preventing wire feeding defects and path wear while maintaining the rear-side reel accommodation unit arrangement that enables binding of complex structures
Solution Approach 2:
The friction parameter in the wire feeding path is reduced by introducing the guide part. This parameter change prevents wire feeding defects and extends the service life of the feeding path while maintaining the ability to bind complex structures
3Adaptability or versatility
If the reel accommodation unit is arranged on the rear side of the main body, then complex structures can be bound, but the load on the wire and reel accommodation unit increases
Solution Approach 1:
The guide part serves as a mediator that reduces the load on the wire and reel accommodation unit by minimizing friction during wire feeding and returning operations, enabling reliable binding of complex structures with reduced mechanical stress

AI summary
A binding machine is configured to feed a wire in a first direction, to curl the wire, to surround a to-be-bound object with the wire, to return the wire in a second direction opposite to the first direction, to wind the wire on the to-be-bound object, and to twist the wire, thereby binding the to-be-bound object. The binding machine includes: a main body; a reel accommodation unit; a wire feeding unit; a curl forming unit; a binding unit; a grip; a starter; and a feeding path. The reel accommodation unit is provided in the main body on an opposite side to the curl forming unit with respect to the starter, and the feeding path is provided with a load reducing part configured to reduce a load of the wire or the reel accommodation unit.
