Dual Bridge Crane Wood Machining for Simultaneous Component Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines for machining wood components, such as door and window frames, suffer from low versatility and flexibility due to a single bridge crane, resulting in limited productivity as they can only process one component at a time.
Innovation Solution
A machine with two independent bridge-cranes and operating heads, along with a clamping and carrying assembly, allows simultaneous machining of multiple components and flexible movement for increased productivity and versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single bridge crane is used for machining wood components, then the machine structure is simple and cost-effective, but the versatility and productivity are low because only one component can be processed at a time
Solution Approach 1:
The single bridge crane is divided into two independent bridge cranes, each capable of performing machining operations separately. This segmentation allows simultaneous processing of multiple components while maintaining the simplicity and cost-effectiveness of individual crane units.
Solution Approach 2:
Each bridge crane is equipped with a universal operating head that can perform multiple machining operations (milling, drilling, routing) on different components. This multi-functionality increases versatility without requiring additional specialized equipment for each operation type.
2Productivity
If a single bridge crane with operating head is used, then the device complexity is low, but the flexibility and productivity are limited due to sequential processing of components
Solution Approach 1:
The single operating head is segmented into two independent operating heads, each mounted on a separate bridge crane. This allows parallel execution of machining operations on different components, significantly increasing overall machining speed while keeping each operating head relatively simple in design.
3Productivity
If components are fed manually into clamping vices, then the device complexity is low, but the productivity and efficiency are reduced due to time-consuming manual operations
Solution Approach 1:
The clamping vice is designed with self-acting feeding and ejecting mechanisms that automatically grasp components, move them into position, and eject finished components without manual intervention. This self-service capability dramatically improves handling efficiency while adding only moderate complexity to the clamping system.
