선박 블록의 판접 위치 획득 및 조립 제어를 위한 시스템 개발

초록

Plate position sensing is essential in shipbuilding since the most of the blocks and outfitting parts are assembled on the jigs and fixtures. Tact welding of main plates is the initial process of the curved hull block assembly in shipbuilding. Due to the heavy weight of the main plates it is difficult to set the plate to the accurate position of the jig and fixtures before welding. The conventional masonry process requires much time and manual work in order to achieve the accurate positioning. This labour-intensive process results in relatively high errors and correction works. Due to their larger dimensions and heavier weights, these hull blocks are not ergonomically desirable and, therefore, various mechanical aid devices such as hydraulic balancers or hydraulic jigs are used for the plate alignment. A position-sensing scheme implemented by sensors is presented in this paper in order to align the main plates on the accurate position during the hull block assembly works. Integrating the Infra Red photo sensors and BRP sensors, a small scaled prototype of the position-sensing is developed to get sophisticated control works for the positioning.
