Wire Feeding Mechanism for Upward Rebar Binding Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing binding machines for reinforcing bars face issues with inappropriate wire feeding methods, difficulty in guiding wires to the binding mechanism, and accumulation of foreign matters that can cause malfunctions, particularly when used in facility apparatus where the binding machine is oriented upwards.
Innovation Solution
A binding facility with a wire feeding mechanism that includes a reel accommodation part, a binding mechanism, a wire pullback mechanism, and a wire feeding mechanism with a wire pullout mechanism to manage wire feeding and guide wires effectively, while also incorporating a design to discharge foreign matters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a binding machine is installed in a facility apparatus and used upward oriented to bind reinforcing bars from below, then the binding operation can be performed effectively, but foreign matters (shavings, cut wires, debris) accumulate inside the binding machine causing malfunctions
Solution Approach 1:
The patent extracts the harmful foreign matters (shavings, cut wires, debris) from the binding machine interior using a discharge mechanism. This includes providing a discharge port and discharge means that actively remove accumulated foreign matters from the binding mechanism, preventing malfunctions while maintaining the upward-oriented binding operation.
2Adaptability or versatility
If the binding machine is moved to and retreated from binding positions by vertical movement, then the binding operation is flexible, but it becomes difficult to guide the wire continuously from the wire feeding unit to the binding mechanism
Solution Approach 1:
The patent makes the wire guide dynamic by providing a wire guide that can move vertically together with the binding machine. This allows the wire guide to maintain its position relative to the binding mechanism during vertical movement, ensuring continuous and smooth wire feeding from the wire feeding unit to the binding mechanism throughout the binding cycle.
Solution Approach 2:
The patent introduces a wire guide as an intermediary component between the wire feeding unit and the binding mechanism. This wire guide mediates the wire transmission path, ensuring smooth wire feeding by guiding the wire from the wire feeding unit to the binding mechanism while accommodating the vertical movement of the binding machine.
3Device complexity
If a conventional wire feeding mechanism is used with the binding machine, then the structure is simple, but the wire cannot be fed by an appropriate method according to different binding methods
Solution Approach 1:
The patent creates a universal wire feeding mechanism that can adapt to different binding methods. The wire feeding unit is designed with adjustable components that can accommodate various wire types and feeding requirements, allowing the same mechanism to serve multiple binding operations with different wire specifications and feeding patterns.
