Routing Machine Multiple Table Roller Hold-Down
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing routing machines in woodworking, plastics, and aerospace industries lack the capability for continuous manufacturing due to the absence of multiple tables and effective roller hold-downs, necessitating manual intervention for workpiece replacement.
Innovation Solution
A routing machine with multiple stationary worktables and roller hold-down assemblies, where a gantry system with actuated rollers allows continuous operation by retaining and releasing workpieces on each table, enabling the toolhead assembly to seamlessly switch between workpieces without stopping the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a routing machine has only one table, then the structure is simple, but the machine must be stopped to remove finished workpieces and load new ones, reducing productivity
Solution Approach 1:
The routing machine is divided into multiple independent worktables (first worktable, second worktable, third worktable) that can operate independently. The toolhead assembly can process workpieces on different tables sequentially without interruption, allowing one table to be prepared while another is being processed, thus achieving continuous manufacturing.
Solution Approach 2:
Workpieces are pre-positioned on multiple worktables before the machining process begins. The hold-down assemblies are pre-configured to secure workpieces on each table. This preliminary preparation allows the toolhead to immediately begin machining when arriving at each table without waiting for workpiece loading or setup.
2Productivity
If vacuum is used to secure workpieces on the table, then the workpiece is held in position, but the machine cannot maintain continuous operation due to lack of rapid workpiece replacement capability
Solution Approach 1:
The hold-down assemblies use movable rollers that can be dynamically raised and lowered to secure or release workpieces. This dynamic mechanism allows rapid engagement and disengagement of workpieces on each table, enabling quick replacement without manual intervention or complex vacuum system adjustments.
Solution Approach 2:
The hold-down assemblies are automatically actuated by the routing machine system itself during operation. As the toolhead assembly moves between tables, the hold-down assemblies automatically secure workpieces on each table and can quickly release them when needed, making the workpiece replacement process self-service and eliminating the need for external manual operation.
3Reliability
If more than one table is used without roller hold-downs, then continuous manufacturing is possible, but workpieces cannot be securely retained on the tables during machining
Solution Approach 1:
Roller hold-down assemblies serve as intermediary devices between the workpiece and the worktable surface. These rollers can be pressed against the workpiece to secure it during machining and then raised to release it. This intermediary mechanism provides reliable workpiece retention while maintaining the ability to quickly release and replace workpieces, supporting continuous manufacturing operation.

AI summary
A routing machine including a plurality of worktables for supporting at least a first workpiece and a second workpiece, a hold down assembly, and a toolhead assembly for machining the first workpiece on one of the worktables and then machining the second workpiece on another of the worktables. The hold down assembly traverses the worktables with the toolhead assembly to retain the first workpiece on the one worktable and then retain the second workpiece on the other of the worktables such that the first workpiece on the one worktable can be removed and replaced with a new workpiece while the toolhead assembly machines the second workpiece on the other table. A method of machining parts with the routing machine is also disclosed.
