Implementación de un sistema automatizado de pesado, empacado y sellado de productos que se expenden en “Frutilandia Allauca” del cantón Bucay provincia del Guayas.

Abstract

The objective of the present titling work was to implement an automated system for weighing, packing and sealing of products that are sold in the “Frutilandia Allauca” company, in order to improve its sales system and guarantee customers’ reliability. An electrical control scheme and a mechanical system were established for the installation of the necessary components for the automation. The process evolution was controlled by a program developed in an Arduino Mega 2560 controller, which activates the DC 56310-1E500 Gearmotor of the conveyor belt to let dropping the product until the selected weight, determined by two load cells. A direct current (DC) motor was used to open or close the scale gate, controlled by the signal of a capacitive sensor, for the sealing step a stepper motor was used to activate and deactivate the sealant. Two screens were implemented that serve as Human-Machine Interface (HMI). The first one is in charge of the monitoring of the process stages and its use it is the operator’s exclusive. The second is destined for sending the user’s orders. The results obtained from the implementation determined that the system achieved an improvement of 75.26%, reducing the time from 1.5 to 1.3 minutes compared to the manual process. In addition to a reduction of waste of fruits of 45 to 5 pounds equivalent to 86.14%. According to the obtained results, it is concluded that the system allows improving the efficiency of the process of weighing, packing and sealing. To maintain the equipment in optimum working conditions it is recommended to perform maintenance activities indicated in the proposed maintenance plan.
