Solution Overview

Problem

Existing palletizing systems struggle to efficiently arrange metal parts with different weights and geometries on pallets, due to the complexity and variability of these parts.

Innovation Solution

An automatic palletizing system that uses intelligent recognition based on three-dimensional geometry to arrange metal parts on pallets, with an internal buffer for pre-organization according to user-defined criteria, and modules for handling, scanning, and wrapping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional palletizing systems are used for metal parts, then the system can handle standard products, but it fails to efficiently arrange metal parts with different weights and geometries

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The system performs preliminary scanning and recognition of metal parts using 3D geometry detection before palletizing. The internal buffer pre-organizes parts according to weight, dimensions, and geometry, allowing the palletizing process to proceed efficiently without real-time decision-making delays

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system changes the approach from 2D barcode/QR code recognition to 3D geometric parameter recognition. By analyzing actual physical dimensions, weight distribution, and spatial orientation of metal parts, the system adapts palletizing arrangements to suit diverse geometries while maintaining high throughput

Inventive Principle:
Principle #35Parameter changes

2Extent of automation

If manual arrangement of metal parts is used, then flexibility in handling different geometries is achieved, but automation and continuity are lost

Engineering Contradiction:

Core Design Contradiction:
Extent of automationVSEase of operation

Solution Approach 1:

The system replaces manual mechanical arrangement with automated robotic manipulation guided by 3D vision systems. The robot uses force control and adaptive grasping to handle diverse metal part geometries, achieving high automation while simplifying operation through software-based geometric analysis

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system introduces an intermediary internal buffer between part reception and palletizing. This buffer pre-organizes parts by geometry and weight, allowing the robotic system to operate continuously without complex real-time decision-making, thus achieving both automation and operational simplicity

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If continuous palletizing is implemented, then productivity increases, but interruption risks from part variability increase

Engineering Contradiction:
Improvecontinuity of palletizing processVSAvoidprocess stability with part variability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs preliminary sorting and organization of metal parts in the internal buffer based on scanned 3D geometry and weight data. By pre-grouping compatible parts before the palletizing robot begins work, the system ensures continuous operation without interruptions from part variability

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from the 3D scanning system to continuously monitor part geometry and weight characteristics. This feedback loop allows the internal buffer to dynamically adjust part organization, ensuring the robotic palletizer can maintain continuous operation despite variations in metal part specifications

Inventive Principle:
Principle #23Feedback

AI summary

The palletizing system comprises a series of modules interconnected to each other. It has a central part having a first zone on which parts handling means are arranged, which may consist of a robot or a conveyor means and, in both embodiments, in combination with palletizers, a feeding module is arranged on one side of the central zone which is followed by scanning means. After said first zone of the central part a second zone or intermediate zone is arranged which has two facing palletizing modules arranged on either side of the central part and after them tray storage modules. Finally, the central part has a wrapping, weighing and labelling module followed by an outlet and loading module or zone. The system allows the automated arrangement of the metal parts on a pallet.
