Solution Overview

Problem

Existing systems for automatically loading metal bars onto operating units, such as bending or cutting machines, face challenges in ensuring reliable, orderly, and space-efficient operation, particularly in minimizing longitudinal space occupation during the loading process.

Innovation Solution

A system and method for automatically picking up and transferring metal bars from a magazine to an operating unit, utilizing a chain-driven conveyor system with transverse arms and a magnet-based pick-up device, which separates and feeds bars one at a time into the operating unit without substantial longitudinal movement, ensuring efficient use of space and precise loading.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional automatic loading systems are used to feed bars to operating units, then bars can be loaded automatically, but the longitudinal space occupation is excessive and the operation is not sufficiently reliable or orderly

Engineering Contradiction:
Improveloading reliabilityVSAvoidlongitudinal space occupation
Core Design Contradiction:
ReliabilityVSLength of stationary object

Solution Approach 1:

The patent transitions from longitudinal bar movement to transverse movement by introducing a vertical lifting mechanism. Bars are picked up from the magazine floor and transferred horizontally to the operating unit at elevated position, then deposited. This dimensional change eliminates the need for long longitudinal conveyance paths while maintaining automatic loading functionality and reliability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent introduces an intermediary transfer platform at elevated position that mediates between the magazine and operating unit. This intermediate station allows bars to be lifted vertically from the magazine, moved transversely along the platform, and then deposited onto the operating unit, thereby avoiding direct longitudinal movement through the entire system length.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If bars are fed one at a time to the operating unit, then loading precision and control are improved, but the loading time and operational speed may be reduced

Engineering Contradiction:
Improveloading precisionVSAvoidloading speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent implements preliminary positioning where bars are picked up from predetermined positions on the magazine floor and placed in a ready state on the transfer platform before being fed to the operating unit. This preliminary action ensures precise control over which bar is fed next while the elevated transverse platform allows multiple bars to be staged and ready for quick sequential transfer, maintaining both precision and speed.

Inventive Principle:
Principle #10Preliminary action

AI summary

Described herein are a system and a method for the treatment of metal bars, in particular bars for the reinforcement of concrete, provided in which is at least one operating unit (1), such as, for example, a bending unit or a cutting unit. A device for picking up, separating, and transferring the bars automatically feeds a plurality of bars to the operating unit (1) picking them up in any desired predetermined number from a bundle of bars deposited in a magazine (M) and separating them from the remaining bars of the bundle. The bars are picked up, separated from the bundle, and transferred to the operating unit by displacing them substantially only in a direction (X) transverse with respect to their longitudinal direction.
