An Intelligent Mechanism for Automated Storage and Retrieval Systems in Smart Warehouse Model

Abstract

This study proposed and implemented telescopic fork transmission mechanisms for automated storage and retrieval system (AS/RS) stacker cranes in the smart warehouse model. The strict initial requirements of the system comprise high payload, high positioning accuracy, low taping deformation, high acceleration transmission, and low noise. To realize these concerns, two versions of telescopic fork transmission mechanisms were approached and conducted. Specifically, the first version applies a cable roller combined with a timing belt transmission, and the improved version utilizes a timing belt. The experimental results demonstrate the superior performance of the enhanced version. The achieved results for the improved version include: the maximum taping deformation is 0.6 mm; the positioning accuracy is ±0.2mm; the backlash of the mechanism is 0.037 mm; the noise level is 43.6 dB for closed-door room operation. These performance parameters all satisfy the initial requirements. Moreover, the performance indicators of the improved version are mostly superior except for the noise level compared with the first version.
