Integrated Panel Edge Trimming Units for Compact Four-Side Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing veneering machines require multiple working units for trimming panel edges, leading to increased space requirements and potential interference issues due to the need for precise control of cutting tools in different directions.
Innovation Solution
A single trimming group with two integrated trimming units, each equipped with cutters having straight and curved sections, minimizes space by allowing simultaneous trimming of all four edges and avoids interference through parallel, inclined guides and actuators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate working units are used for trimming front/rear ends and top/bottom ends, then trimming functionality is complete, but the space required and total length of the veneering machine increase
Solution Approach 1:
The patent combines two separate trimming working units into a single integrated trimming unit that can trim all four ends (front, rear, top, bottom) of the panel edge. This merging eliminates the need for separate working units spaced apart in the panel feed direction, thereby reducing the total length of the veneering machine while maintaining complete trimming functionality.
Solution Approach 2:
The single trimming unit is designed with multi-functionality to perform both front/rear end trimming and top/bottom end trimming. The unit includes cutting tools and positioning means that can operate at different locations along the panel edge, allowing one universal unit to replace two specialized units, thus reducing space requirements.
2Manufacturing precision
If multiple cutting tools with different cutting edges are used for different edge ends, then trimming precision is improved, but device complexity and control difficulty increase
Solution Approach 1:
The patent employs a single cutting tool with a multi-section cutting edge that can perform different trimming operations (front, rear, top, bottom ends) depending on its position and orientation. This universal cutting tool eliminates the need for multiple specialized cutting tools, thereby reducing device complexity and control difficulty while maintaining trimming precision through the varied geometry of the cutting edge sections.

AI summary
The invention relates to a device for trimming panel edges, which comprises a first trimming unit (10) for trimming the front end (C1) and the bottom end (C2), and a second trimming unit (20) for trimming the upper end (C3) and the rear end (C4), of an edge (C) of a panel (P) by means of respective milling cutters (108, 208). The trimming units (10, 20) comprise a first actuator and a second actuator (102, 202) that make contact with the panel (P) and four lateral copiers (110, 111, 210, 211) that make contact with the edge during the trimming of the respective ends of the edge (C). The lateral copiers can be independently arranged in a forward position or in a rear position, in which positions the milling cutters of the trimming units (10, 20) make a straight cut or a rounded cut, respectively, in the corresponding end (C1-C4) of the edge.
