Sheet Processing Machine With On-the-Fly Underside Marking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet processing machines require additional time for marking workpieces, which can be time-consuming and inefficient, especially when combined with other processing operations like drilling, milling, or cutting.
Innovation Solution
A sheet processing machine with a stationary frame, a processing tool, a marking tool, and an XY-guide assembly that allows the marking tool to move independently relative to the processing tool, enabling simultaneous marking during sheet material movement along a roller conveyor, thus reducing the need for extra time dedicated to marking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate marking operation is performed after processing, then marking precision can be ensured, but total processing time increases
Solution Approach 1:
The patent combines the marking tool with the processing tool into a single integrated unit that can perform both marking and processing operations simultaneously. The marking tool is positioned on the same bridge structure as the processing tool, allowing both functions to be executed in one positioning cycle, thereby eliminating the need for separate marking operations and reducing total processing time while maintaining marking precision through the same high-precision positioning system.
Solution Approach 2:
The marking tool enables continuous operation by performing marking during the same positioning cycle as processing operations. The system can mark workpieces while moving between processing positions or during idle time in the processing cycle, ensuring that the marking function does not interrupt the overall production flow and maintaining continuous useful action throughout the processing sequence.
2Adaptability or versatility
If a marking tool is added to the machine, then marking capability is improved, but device complexity increases
Solution Approach 1:
The marking tool is designed as a multi-functional component that can perform marking operations while being integrated into the existing processing tool structure. The same bridge, positioning system, and control mechanisms that manage the processing tool are utilized for the marking tool, allowing one component to serve multiple functions without proportionally increasing overall system complexity.
Solution Approach 2:
Instead of adding a separate marking machine or complex dedicated marking system, the patent inverts the approach by making the processing tool structure serve dual purposes. The processing tool bridge and positioning infrastructure are designed to accommodate both processing and marking functions, effectively using the processing structure as the foundation for marking capability rather than adding independent marking infrastructure.
3Device complexity
If marking is performed on the same side as processing, then tool coordination is simplified, but tool interference occurs
Solution Approach 1:
The marking tool is positioned asymmetrically relative to the processing tool, specifically on the opposite side of the workpiece. This asymmetric arrangement allows both tools to operate simultaneously without physical interference, as they approach the workpiece from different sides. The positioning system maintains coordinated control of both asymmetrically positioned tools, ensuring proper timing and positioning despite their different locations.

AI summary
A sheet processing machine having a stationary frame and comprising a transport table for transporting and supporting a sheet material. The transport table comprises a roller conveyor comprising a plurality of roller and a gap between two of the plurality of rollers. The machine further comprises a processing tool for processing the sheet material at a first side of the sheet material, as well as a marking tool for marking the sheet material at a second side of the sheet material, opposite the first side. The machine additionally has an XY-guide assembly arranged in or at the gap and connecting the marking tool to the stationary frame and enabling a movement of the marking tool with respect to the stationary frame. The movement of the marking tool with respect to the stationary frame is independently controllable relative to a movement of the processing tool with respect to the stationary frame.
