Panel Cutting Machine With Split Trapdoor for Continuous Swarf Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting machines for wood panels can only cut panels when the discharge trapdoor is in its closing position, limiting simultaneous cutting operations as the trapdoor must alternate between closing and opening positions to manage swarf from different panels.
Innovation Solution
A cutting machine design featuring independently movable support plates of the discharge trapdoor and a robotic manipulator, allowing the cutting assembly to operate regardless of the trapdoor's position, enabling continuous cutting of panels by both the main and secondary pushers without the need for thrust bars, and facilitating efficient swarf discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If the discharge trapdoor is moved to its opening position to discharge swarf, then swarf discharge is enabled, but cutting operations must be stopped
Solution Approach 1:
The discharge trapdoor is segmented into two independent movable support plates that can move independently. This allows one plate to be in the opening position for swarf discharge while the other remains in the closing position to support active cutting operations, resolving the contradiction between swarf discharge and cutting continuity
Solution Approach 2:
The trapdoor system transitions from a static single-position design to a dynamic multi-position design where the two support plates can independently transition between closing and opening positions. This dynamic capability enables continuous cutting operations while maintaining swarf discharge functionality
2Device complexity
If a single discharge trapdoor is used, then device complexity is reduced, but simultaneous cutting of multiple panels is prevented
Solution Approach 1:
The single discharge trapdoor is divided into two independent movable support plates, each capable of independent movement between closing and opening positions. This segmentation enables simultaneous cutting of multiple panels while maintaining relative simplicity in the overall trapdoor structure
Solution Approach 2:
Each support plate serves multiple functions: it can independently support panels for cutting operations, enable swarf discharge when opened, and work in coordination with the other plate to maintain both cutting and discharge capabilities simultaneously

AI summary
A cutting machine to cut panels (2) made of wood or the like has a main pusher (21) to move one first panel (2) through a cutting station (17), a secondary pusher (22) to move one second panel (2) through the cutting station (17), and a discharge trapdoor (14) to discharge swarf under the support surface (P) of the panels (2); the discharge trapdoor (14) being defined by at least two support plates (15, 16), which are aligned with one another and are movable independently of one another between respective closing positions and respective opening positions.
