Wood Panel Cutting Machine Locking Device for Component Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines for cutting wood panels struggle to properly hold and prevent rotation of components with reduced width, as the pressing device exerts high pressure on the panel but low pressure on the separated components, leading to instability during cutting.
Innovation Solution
The machine incorporates a locking device that engages the component with a locking plate and a sucking pneumatic member to prevent rotation, and a blowing rod to manage shavings, ensuring stability and secure holding of components during cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pressing device is positioned to press the panel, then the panel is securely held, but the separated component cannot be properly held and prevented from rotating
Solution Approach 1:
The pressing device is segmented into two independent pressing members that can be independently controlled. The first pressing member handles panel clamping operations, while the second pressing member specifically addresses component holding and rotation prevention. This segmentation allows each member to be optimized for its specific function, improving both ease of operation for panel clamping and reliability for component holding.
Solution Approach 2:
The pressing device is designed with multi-functionality to perform both panel clamping and component holding/rotation prevention through its two pressing members. This universal design allows a single device to handle multiple tasks that were previously requiring separate mechanisms, improving both operational ease and reliability across different cutting scenarios.
2Device complexity
If a simple pressing device is used, then the machine structure remains simple, but it cannot prevent rotation of components with reduced width
Solution Approach 1:
The pressing device is segmented into two pressing members within a single device structure. This segmentation adds the necessary functionality to prevent component rotation while maintaining overall structural simplicity. The first pressing member maintains the simple design for panel clamping, while the second pressing member adds the rotation prevention capability without requiring a completely complex new device.
Solution Approach 2:
The function of preventing component rotation is merged into the existing pressing device structure by adding a second pressing member. This combining approach integrates the rotation prevention function with the panel clamping function in a unified device, avoiding the need for separate complex mechanisms and maintaining relative structural simplicity while improving reliability.

Implementation Method 1
a sucking pneumatic member (42) mounted on the pressing device (31) and mobile between a sucking position, in which the member (42) holds the component (38) to prevent its rotation around the axis (40), and a non-sucking position
Implementation Method 2
a blowing rod (35) extending in the vertical direction (28) and mobile, relative to the slide (34), in the vertical direction (28) between a lowered operating position, in which the rod (35) engages a infeed channel (36) created by the tool (29) through the panel (2) parallel to the direction (7), and a raised resting position
