Solution Overview

Problem

Current cutting systems for elongated products, such as metal profiles or rods, face inefficiencies due to a limited number of optimisation compartments, leading to increased waste, noise, and operational challenges, as they rely on gravity for unloading, which restricts the expansion of storage capacity and complicates downstream processing.

Innovation Solution

A method and manipulator assembly that uses a gripping device to transfer cut products from a measuring path to storage compartments, allowing for a greater number of compartments and reducing noise by eliminating gravity-driven unloading, enabling efficient storage and processing without the need for extensive height adjustments or expensive equipment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If gravity-driven unloading is used to access optimisation compartments, then the system structure is simple, but the number of compartments is limited and noise is generated

Engineering Contradiction:
Improvenumber of optimisation compartmentsVSAvoidnoise from gravity-driven unloading
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the gravity-driven mechanical unloading system with an automated manipulator system that uses controlled mechanical movement. The manipulator with gripping devices picks up cut products and places them in compartments, eliminating the noise generated by gravity-driven unloading while enabling a greater number of compartments to be used.

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

Solution Approach 2:

The manipulator assembly acts as an intermediary between the measuring path and the storage compartments. It mediates the transfer of cut products, allowing flexible access to any compartment without being constrained by gravity-driven unloading limitations, thereby increasing the number of available optimisation compartments.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If the cutting system is raised to increase height for gravity access, then more compartments can be accessed, but costs increase and maintenance accessibility worsens

Engineering Contradiction:
Improvenumber of accessible compartmentsVSAvoidsystem cost and maintenance accessibility
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

The patent introduces a dynamic manipulator system that can move vertically and horizontally to access compartments at any height. This dynamic system eliminates the need to permanently raise the cutting system, as the manipulator can adapt its position to access any compartment, reducing manufacturing costs and improving maintenance accessibility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The manipulator assembly serves multiple functions: it transfers cut products to compartments, accesses any compartment regardless of height, and can be repositioned for maintenance. This multi-functionality replaces the need for a permanently elevated cutting system, reducing costs while maintaining access to all compartments.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If more optimisation compartments are used to reduce waste, then cutting efficiency improves, but the system complexity increases

Engineering Contradiction:
Improvecutting optimisation efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The manipulator system operates autonomously to transfer cut products to the appropriate optimisation compartments based on computer control. This self-service capability allows the system to manage a large number of compartments without proportionally increasing operational complexity, as the manipulator automatically selects and fills the correct compartments to maximise cutting efficiency.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses computer control with feedback mechanisms to manage the manipulator's movements and compartment selection. This feedback system optimizes the use of multiple compartments by tracking which compartments are full and which need filling, enabling efficient waste reduction without manual intervention, thereby managing system complexity through automated control.

Inventive Principle:
Principle #23Feedback

AI summary

The manipulator assembly for elongated products, in particular metal bars or profiles for reinforced concrete, is associable with a measuring path (4) arranged downstream of a cutting assembly (3) in a longitudinal feeding direction (Y), for receiving on a respective receiving plane (4a) products (2a) cut by the cutting assembly (3), and with a storage (6) arranged at the side of the measuring path (4). The manipulator assembly (10, 10") comprises at least one gripping device (11) movable with respect to the measuring path (4) and to the storage (6), in a collecting motion according to a collecting direction (Z) to collect at least a part of the cut products (2a), in a transfer motion for transferring the collected cut products (2a) to the storage (6) and in an unloading motion according to an unloading direction (Z) to release the collected cut products (2a) or part of them in the storage (6).
