Recovery Box Brush Insertion Layout to Prevent Swarf Cleaner Breakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machining swarf removing apparatuses face issues with increased size and brush breakage due to the insertion method of brushes into recovery boxes, where brushes contact the inner wall, applying a load that can cause breakage and result in larger device dimensions.
Innovation Solution
A machining swarf removing apparatus with a brush that is designed to move in a way that it does not contact the inner wall during insertion, utilizing a lifting and lowering unit, rotating unit, and control unit to orient the brush for safe insertion and operation, reducing size and preventing breakage, and incorporating a vibrating unit for enhanced removal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the brush is inserted into the duct from a side which is outside in a width direction of the duct, then the brush can be inserted easily, but the size in the width direction of the device increases
Solution Approach 1:
The brush insertion direction is changed from the width direction (lateral insertion) to the height direction (vertical insertion). The brush is inserted from the upper surface of the recovery box through the opening, moving along the height dimension instead of the width dimension. This dimensional change allows the brush to be inserted easily while avoiding an increase in device width.
2Ease of operation
If the brush is inserted into the duct, then the brush contacts the inner wall of the duct, but this results in a load being applied to the brush and the brush may be broken
Solution Approach 1:
The brush orientation is adjusted in advance before insertion. The control unit rotates the brush so that its long side is oriented in the width direction before the brush is inserted into the recovery box. This preliminary orientation adjustment ensures that during vertical insertion, the brush does not contact the inner wall, preventing load application and potential breakage.
3Length of stationary object
If the brush is inserted vertically into the recovery box, then the device width is reduced, but the brush must be precisely oriented to avoid contact with the inner wall
Solution Approach 1:
The brush is made rotatable about its axial direction by a rotating unit, transforming it from a static component to a dynamic one. The control unit can adjust the brush orientation dynamically, rotating it to the appropriate angle before insertion. This dynamic capability allows precise orientation control to prevent inner wall contact while maintaining compact device dimensions.
Solution Approach 2:
A rotating unit is introduced as an intermediary mechanism between the brush and the drive mechanism. This rotating unit serves as a mediator that adjusts the brush orientation before insertion, enabling the brush to be properly positioned without direct complex control of the brush itself, thus managing the complexity while achieving the desired orientation.

AI summary
A machining swarf removing apparatus includes a left and a right machining swarf removing units. When removing machining swarf adhered to a recovery box, the left machining swarf removing unit is placed in removal starting position. A brush enters an insertion-ready state in which transverse direction thereof is oriented in a second direction D2. The brush is moved to an insertion position for insertion into the recovery box, then the brush is rotated to enter a machining swarf removal-ready state in which a longitudinal direction thereof is oriented in the second direction D2. The left machining swarf removing unit is moved to remove the machining swarf adhered to the recovery box by the brush, while a left rod vibrating device is driven to vibrate a rod, vibrating the brush attached to the rod.
