Solution Overview

Problem

Existing binding machines for reinforcing bars lack the ability to determine and execute a precise timing for moving away from a binding position, leading to inefficiencies in the binding process.

Innovation Solution

A binding device comprising a binding machine and a transfer robot that coordinates the movement of the binding machine and reinforcing bars to separate at a predetermined timing, allowing for synchronized operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If the binding machine performs binding operation at a binding position, then the binding function is achieved, but the timing for moving away from the binding position cannot be determined in advance

Engineering Contradiction:

Improvetiming for moving binding machineVSAvoidcoordination between binding machine and transfer robot

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The binding machine detects completion of the binding operation and sends a signal to the transfer robot. This feedback mechanism allows the transfer robot to determine the appropriate timing for moving the binding machine away from the binding position, resolving the timing uncertainty while maintaining system coordination.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The transfer robot is positioned and ready to move the binding machine in advance. Upon receiving the completion signal from the binding machine, the transfer robot executes the movement operation immediately, ensuring seamless coordination without delaying the binding process.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the transfer robot moves the binding machine after binding operation ends and motor stops, then the binding machine can be repositioned, but the timing of movement cannot be advanced

Engineering Contradiction:

Improveefficiency of binding processVSAvoidwaiting time for movement

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The binding machine continues its binding operation without interruption. The transfer robot waits for the completion signal and then immediately executes the movement, ensuring that the useful action (binding) continues continuously without unnecessary waiting time, thereby improving overall productivity.

Inventive Principle:

Principle #20Continuity of useful action

3Adaptability or versatility

If multiple binding machines are arranged in rows, then reinforcing bars can be bound at multiple positions, but coordination of movement timing becomes difficult

Engineering Contradiction:

Improvemulti-position binding capabilityVSAvoidcoordination of multiple binding machines

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Each binding machine independently detects its own binding completion and sends signals to the transfer robot. The transfer robot receives signals from multiple binding machines and coordinates movements based on these self-generated signals, eliminating the need for complex external coordination mechanisms while enabling multi-position binding capability.

Inventive Principle:

Principle #25Self-service

AI summary

A binding device including: a binding machine that binds reinforcing bars with a wire; and a transfer robot that moves the binding machine and the reinforcing bars positioned at a binding position in a direction of approaching and a direction of separating from each other by a relative movement of the binding machine and the reinforcing bars. The binding machine is configured to determine, when the binding machine starts an operation of binding the reinforcing bars with the wire, a timing of moving the binding machine and the reinforcing bars in the direction of separating from each other, and the transfer robot is configured to move the binding machine and the reinforcing bars in the direction of separating from each other at the determined timing.
