External Binding Wire Supply System for Rebar Robots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional self-propelled robots for binding reinforcing bars require frequent stops to replace binding wire reels, leading to low work efficiency due to the limited capacity of the binding wire accommodating magazine.
Innovation Solution
A binding wire supply system comprising a reel mounting unit, a binding wire adapter, and a binding wire insertion guide that allows continuous supply of binding wire from outside the reinforcing bar binding machine, eliminating the need for reel replacement within the magazine, and incorporating a reverse rotation prevention member to manage wire tension and prevent wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the binding wire is stored in the binding wire accommodating magazine, then the binding operation can be performed, but the work efficiency is low due to frequent reel replacement
Solution Approach 1:
A binding wire supply reel is introduced as an intermediary component, positioned externally to the binding machine. This supply reel feeds binding wire to the magazine through a guide, allowing continuous supply without stopping the robot or opening the magazine. The intermediary supply reel acts as a buffer that decouples the binding operation from the limited magazine capacity.
Solution Approach 2:
The binding wire supply system is relocated from the internal magazine dimension to an external dimension. The supply reel is mounted on the robot arm or frame, positioned in space outside the magazine, and feeds wire through a guide into the magazine. This spatial reconfiguration allows continuous supply without interfering with the magazine's internal structure or operation.
2Duration of action of stationary object
If the binding wire supply reel is arranged close to the binding machine, then continuous supply is enabled, but the system complexity increases
Solution Approach 1:
The binding wire supply reel is integrated with existing robot components, serving multiple functions. It can be mounted on the robot arm or frame, utilizing the robot's existing motion capabilities for positioning. The guide structure also serves dual purposes: guiding the wire and potentially acting as a tensioning element. This multi-functionality reduces the need for entirely new components.
Solution Approach 2:
The binding wire supply system is designed to be self-regulating. The guide structure automatically tensions and guides the wire as it feeds from the supply reel to the magazine. The system uses the robot's own motion and the wire's tension to maintain proper feeding, without requiring additional active control mechanisms or power sources for the supply function.

AI summary
A binding wire supply system for a reinforcing bar binding machine for supplying binding wire to a reinforcing bar binding machine from the outside of the reinforcing bar binding machine that binds intersections of reinforcing bars with the binding wire, wherein the binding wire supply system includes a reel mounting unit on which a binding wire supply reel, which is arranged close to the reinforcing bar binding machine and supplies the binding wire to the reinforcing bar binding machine, is mounted; a binding wire adapter for introducing the binding wire supplied from the binding wire supply reel into a binding wire accommodating magazine of the reinforcing bar binding machine; and a binding wire insertion guide into which the binding wire is inserted from the reel mounting unit to guide the binding wire to the binding wire adapter.
