Saw Chip Collection Assembly for Variable Workpiece Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sawing machines face challenges in effectively collecting cutting chips from workpieces of different thicknesses due to limitations in dust collection member positioning, leading to inefficient chip collection and potential environmental pollution.
Innovation Solution
A sawing machine design featuring a chip collection assembly with a workpiece position detecting member and a chip guiding member, connected by a rod set, allowing the chip guiding member to adjust its position relative to the workpiece, ensuring chips can enter a chip collection tube regardless of workpiece thickness, with the ability to move upward for thicker pieces and downward for thinner pieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the dust collection member is positioned at a fixed high location to collect chips from thick workpieces, then chip collection for thick workpieces is improved, but chip collection for thin workpieces deteriorates
Solution Approach 1:
The dust collection member is made movable rather than fixed, allowing it to adjust its position dynamically. The member can move vertically along the rocker arm to align with the top surface of workpieces of different thicknesses, ensuring effective chip collection for both thick and thin workpieces.
Solution Approach 2:
The dust collection member is designed to serve multiple functions by being repositionable. It can collect chips from both thick workpieces (when positioned higher) and thin workpieces (when positioned lower), making a single component universally applicable to different workpiece thicknesses.
2Reliability
If the dust collection member is positioned at a fixed low location to accommodate thin workpieces, then chip collection for thin workpieces is improved, but chip collection for thick workpieces deteriorates
Solution Approach 1:
The dust collection member can dynamically adjust its vertical position along the rocker arm. When processing thick workpieces, it moves to a higher position; when processing thin workpieces, it moves to a lower position, maintaining optimal chip collection effectiveness across different thicknesses.
Solution Approach 2:
The repositionable dust collection member provides universal chip collection capability for workpieces of varying thicknesses, eliminating the need for separate collection systems for thick and thin workpieces.
3Adaptability or versatility
If a soft rubber mask is used instead of a dust collection member to adapt to different workpiece thicknesses, then adaptability is improved, but reliability deteriorates due to mask damage
Solution Approach 1:
The invention replaces the disposable soft rubber mask with a durable, repositionable dust collection member. The member can be adjusted vertically along the rocker arm to adapt to different workpiece thicknesses without being damaged, providing long-term reliability.
Solution Approach 2:
Instead of using a flexible rubber mask that degrades under prolonged contact, the invention employs a rigid but repositionable dust collection member that slides along the rocker arm, maintaining structural integrity and collection effectiveness over time.

AI summary
A sawing machine includes a worktable on which a workpiece is fixed, a rocker arm pivotally connected with the worktable, and a saw blade rotatably mounted to the rocker arm. The rocker arm includes a chip collection tube. A workpiece position detecting member and a chip guiding member are movably connected with the rocker arm by a connecting rod set in a way that the workpiece position detecting member is moveable by the workpiece, and the chip guiding member is in communication with the chip collection tube and moveable along with the workpiece position detecting member to a position adjacent to a top surface of the workpiece. As such, the sawing machine effectively collects chips generated during the sawing process of the workpieces having different thicknesses.
