Mechanism for Transactions in Vending Appliance

Abstract

Engineers are constantly looking for solutions that provide society with convenience at a reasonable price because of the widespread change in the social market for purchasing goods and/or services. Vending machines, which can serve as a platform for transaction with minimal inventory and human power, are one option. Therefore, a robust and dependable vending machine, particularly its transaction mechanism, is essential. The conceptual design of a cash-based transaction mechanism for vending machines is the subject of this paper. Using a Fused Deposition Modelling (FDM) 3D printer, the prototype mechanism was developed and made. which uses PLA as its filament material. Using a random selection of 10 cents, 20 cents, and 50 cents (from various generations), this prototype has been tested continuously. According to the findings, the sequential rate of sorting 10 cents is the lowest of all. This is primarily due to the position of the hopper, which leaves the servo motor with insufficient time to perform the intended action on time. This paper will go into greater detail about the decision-making logic and comprehensive mechanical design.
