Wheel Rim Scrap Removal Using Sequential Air-Blowing Nozzles

The patent implements an automatic scrap removal system where the blowing device autonomously removes scraps from the wheel rim without requiring manual operation. The system uses positioning members to automatically align the wheel rim and blowing nozzles, and control logic to automatically activate the blowing sequence, making the entire scrap removal process self-service and eliminating the need for workers to manually operate blowout gas guns.

The patent replaces the manual mechanical operation of blowout gas guns with an automated pneumatic system. The blowing device is controlled by a control unit that automatically activates compressed air supply to multiple blowing nozzles in a specific sequence, substituting human mechanical action with an automated mechanical-pneumatic system that achieves faster and more consistent scrap removal.

The system performs scrap removal automatically without human intervention in the dangerous zone. The wheel rim is positioned on positioning members that hold it stationary, and the blowing nozzles are automatically activated in sequence to blow scraps away, eliminating the need for workers to be present during the high-pressure air blowing operation, thus ensuring worker safety.

The patent introduces positioning members as intermediaries between the wheel rim and the blowing device. These positioning members securely hold the wheel rim in a fixed position and provide a reference framework for the blowing nozzles, acting as a mediator that enables automated operation while protecting workers from exposure to high-pressure air and flying scraps.

The patent divides the scrap removal function into multiple independent blowing nozzles positioned at different locations and angles. Each nozzle targets specific areas of the wheel rim (inner circumference, outer circumference, notch regions) with compressed air. This segmented approach ensures comprehensive coverage of all potential scrap locations, achieving complete removal that a single manual blowout gun cannot accomplish consistently.

The control unit activates the blowing nozzles in a specific periodic sequence rather than simultaneously or randomly. The control logic systematically activates each nozzle group in turn, ensuring that all areas of the wheel rim are targeted methodically. This periodic, systematic action pattern guarantees complete scrap removal by covering every region in an organized sequence, preventing incomplete removal defects.
