Solution Overview

Problem

Existing reinforcing bar binding machines face challenges in stabilizing the position of wires intersecting the direction of wire feeding, leading to variations in the axial direction of the annular feeding path, which can result in the wire end not entering the guide correctly, especially when the diameter of the reinforcing bars increases.

Innovation Solution

The binding machine incorporates a curling guide and a leading guide to regulate the movement of the wire in the direction intersecting the wire feeding direction, using a magazine with a feeding path forming portion and a regulating portion to stabilize the wire position along the axial direction of the annular feeding path, ensuring the wire enters the leading guide correctly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the diameter of the annular feeding path is increased to accommodate larger reinforcing bars, then the binding machine can handle larger reinforcing bars, but the position of the wire along the axial direction varies, causing the wire end to fail to enter the guide correctly

Engineering Contradiction:
Improvecapability to handle larger reinforcing barsVSAvoidposition stability of wire along axial direction
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

A regulating portion is introduced as an intermediary element between the reel and the curling guide. This regulating portion mediates the wire's path by regulating its position in the axial direction, ensuring that the wire end correctly enters the guide even when the annular feeding path diameter is increased for larger reinforcing bars.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the wire position in the direction intersecting the feeding direction is biased in the magazine, then the wire may be easier to feed, but the variation in wire position along the axial direction increases, causing the wire end to not enter the guide

Engineering Contradiction:
Improveease of wire feedingVSAvoidwire position variation along axial direction
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The regulating portion changes the spatial parameters of the wire path by constraining the wire's position in the axial direction. This parameter change ensures that even when the wire is biased in the magazine for easier feeding, the axial position variation is controlled and the wire end correctly enters the guide.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If the diameter of reinforcing bars increases, then the binding machine can process larger structures, but wire entanglement with the reel increases and operability deteriorates

Engineering Contradiction:
Improvecapability to bind larger reinforcing barsVSAvoidoperability and wire alignment
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The regulating portion serves as a mediator that prevents wire entanglement with the reel by controlling the wire's axial position. This intermediary element maintains proper wire alignment and operability even when processing larger reinforcing bars with increased annular feeding path diameter.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A binding machine includes a magazine configured to accommodate a wire, a wire feeding portion configured to feed the wire accommodated in the magazine, a curl forming portion configured to constitute an annular feeding path for winding the wire fed by the wire feeding portion around a binding object, and a binding portion configured to twist the wire wound around the binding object. The curl forming portion includes a curling guide that curls the wire fed by the wire feeding portion, and a leading guide that leads the wire curled by the curling guide to the binding portion. The magazine includes a feeding path forming portion that forms a feeding path of the wire, and a regulating portion that regulates movement of the wire in a direction intersecting a direction in which the wire is fed in the feeding path forming portion.
