Rod Handling with Reference Marking for Straightness Re-Phasing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the production of slender artifacts, such as rods and wires, there is a loss of information regarding the original position and rotational orientation of the material during the machining process, which limits the accuracy of straightness measurements and corrective actions in upstream processes.
Innovation Solution
Applying a reference mark on the rod during cutting, followed by a transport system with synchronized clamps that prevent rotation and longitudinal translation, allowing for precise tracking of the rod's position and orientation throughout the machining process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the wire is cut into discrete rods during the machining process, then the production process can proceed to end machining operations, but the rotational orientation and longitudinal position information of the rod inside the continuous wire is lost
Solution Approach 1:
The patent applies a reference mark to the rod immediately after cutting from the continuous wire, before the rod undergoes any machining operations or rotations. This preliminary marking preserves the original position and orientation information that would otherwise be lost during subsequent processing steps
Solution Approach 2:
The reference mark acts as an intermediary element that carries information about the rod's original position and orientation throughout the machining process. This mark serves as a mediator between the cutting operation and subsequent measurement operations, enabling traceability of the rod's history
2Ease of operation
If traditional transport systems are used without rotation prevention, then the rods can be freely handled during machining, but the original orientation information cannot be preserved for accurate measurement
Solution Approach 1:
The transport system dynamically adjusts its behavior based on the measurement phase: during normal handling it allows freedom of movement, but during measurement it activates rotation prevention mechanisms to ensure the reference mark remains in its original orientation for accurate straightness measurement
Solution Approach 2:
The system uses the reference mark as a feedback mechanism to monitor and control the rod's orientation during transport. By detecting the position of the reference mark, the system can determine whether the rod has rotated and adjust accordingly to maintain measurement accuracy

AI summary
A method and a system for handling slender bodies in a semi-finished production plant includes a cutting station separating slender bodies from a continuous wire, a finishing station of the head ends of the slender bodies, a dimensional verification station downstream of the finishing station, and transporting equipment transporting the slender bodies between stations. At or upstream of the cutting station a marking unit applies a reference marking on the slender bodies, which working identifies an original attitude including angular position. The transporting equipment includes gripping and locking assembly, locking at least the angular position of the reference mark to a relative reference system of the transport equipment. Upstream of the finishing station is a detecting and storing unit for data of the angular position to the relative reference system. A unit determines the original attitude of the slender bodies using the data in the dimensional verification station.
