Sawing Machine Pusher Runner Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sawing machines for wood panels have long operating cycles due to the need for multiple movements of the carriage to position and cut the panel, and the thickness of the pushing element is limited, compromising stability and correct movement.
Innovation Solution
A sawing machine design featuring a roller conveyor with a gripping and conveying unit, a cutting station with a carriage supporting a cutter and blade, and a pressing and aspirating unit with cross members and a runner that moves the panel into contact with an abutting element, allowing for efficient cutting and aspiration of shavings, reducing the need for extensive carriage movements and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pushing element is carried by the cutting means carriage, then the panel can be moved into contact with the abutting means, but the operating cycle becomes relatively long due to multiple carriage movements
Solution Approach 1:
The pushing function is separated from the cutting carriage and assigned to an independent pushing means. This segmentation allows the pushing operation to occur independently without requiring the cutting carriage to perform both positioning and cutting functions sequentially, thereby reducing the overall operating cycle time while maintaining proper panel positioning capability
Solution Approach 2:
The panel is moved into contact with the abutting means by the independent pushing means before the cutting operation begins. This preliminary action of positioning the panel in advance allows the cutting carriage to focus solely on the cutting operation without needing to first position the panel, thus reducing the total time required for the complete cutting cycle
2Ease of operation
If the pushing element thickness is reduced to allow movement along the slot, then the element can fit in the slot, but the stability of the pushing element is compromised
Solution Approach 1:
The pushing means is designed with an elongated structure that extends in the feeding direction of the panel. This dimensional extension along the feeding direction provides increased structural stability and rigidity to the pushing means, compensating for the reduced thickness required to fit within the slot constraints, thereby maintaining both movability and stability
3Ease of operation
If the pushing element thickness is reduced, then it can move along the slot, but the correct movement of the panel against the abutting means is compromised
Solution Approach 1:
The pushing means is elongated in the feeding direction to provide increased surface area and structural rigidity. This dimensional change compensates for the reduced thickness, enabling the pushing means to maintain proper panel positioning precision while still fitting within the slot constraints for movement
Solution Approach 2:
The pushing means is constructed with a composite structure combining multiple functional elements: a stable elongated body for structural integrity, a cutting-edge portion for precise panel contact, and positioning features for accurate alignment. This composite design ensures both slot compatibility and precise panel positioning capability

AI summary
A sawing machine is provided with a cutting device (15) mobile on a cutting plane (T) orthogonal to a direction of advancement (4) of a wood panel (2) or the like, of two cross members (23) arranged on opposite sides of the cutting plane (T) for securing the panel (2) against a supporting plane (P), and at least a pushing element (31), which is mounted between the cross members (23), and is mobile on a pushing plane substantially parallel to and distinct from the cutting plane (T) for moving the panel (2) into contact with a corresponding abutting element (32).
