Solution Overview

Problem

Existing profile processing methods result in significant idle time for working machines due to inefficient movement of measuring trucks, especially when handling shorter profiles, which reduces productivity.

Innovation Solution

A method and assembly that determine the longitudinal position of a profile's end using a profile end detection system, allowing the measuring truck to move to an optimal rest position closer to the profile, reducing the distance it needs to travel and minimizing idle time by optimizing the infeed process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the measuring truck moves to the end of the infeed conveyor to transport each profile, then the profile can be fed to the working machine, but the measuring truck travels unnecessary long distances causing idle time for the working machine

Engineering Contradiction:
Improveworking machine productivityVSAvoidmeasuring truck travel time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system determines the longitudinal position of the profile end in advance using a detection system (laser scanner or camera) before the measuring truck arrives. This preliminary position information allows the measuring truck to be pre-positioned or move directly to the optimal pickup point, eliminating unnecessary travel along the entire conveyor length and reducing idle time for the working machine.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

A profile end detection system provides real-time feedback on the longitudinal position of the profile end to the control system. This feedback enables the measuring truck to adjust its position and movement dynamically, optimizing the pickup timing and location. The control system uses this information to coordinate the measuring truck's movement with the profile's position, minimizing travel distance and working machine idle time.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If the measuring truck waits for the profile to be fully transported before moving, then accurate positioning is achieved, but significant idle time occurs especially with shorter profiles

Engineering Contradiction:
Improveprofile position detection accuracyVSAvoidmeasuring truck idle time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The profile end position is detected in advance using optical detection systems (laser scanners or cameras) that can identify the profile end position while the profile is still being transported or before the measuring truck needs to engage. This preliminary detection provides accurate position information without requiring the measuring truck to wait idle, as the system already knows where to position itself for optimal pickup.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces mechanical position detection methods with optical detection systems (laser scanners or cameras). These optical systems can accurately determine the profile end position remotely and continuously without physical contact, providing real-time position data to the control system. This substitution eliminates the need for mechanical waiting and positioning, significantly reducing idle time while maintaining or improving measurement precision.

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

AI summary

A method of processing profiles in a profile processing assembly comprising a working machine and a profile infeed assembly. The profile infeed assembly includes an infeed cross transport assembly, and an infeed conveyor assembly with an infeed conveyor and a measuring truck. The infeed conveyor has a first end remote from the working machine. The infeed cross transport assembly supplies individual profiles to the infeed conveyor assembly. The infeed conveyor assembly supplies individual profiles to the working machine by means of a measuring truck which engages a profile and moves the profile over the infeed conveyor to the working machine. The method comprises determining the longitudinal position of a first end of a profile that is facing away from the working machine and moving the measuring truck to an optimal rest position which is closest to the first end of the profile to be fed onto the infeed conveyor.
