Desarrollo de una máquina multifuncional con control PID, manejo de inventario en la nube, monitoreo de variables por IoT y sistema de supervisión SCADA para la optimización del proceso de empaquetado y sellado de legumbres

Abstract

In many commercial establishments there are different containers with legumes, but these are handled by any individual without the proper biosecurity standards and in addition to this, repetitive and inefficient tasks are carried out that delay the packaging process of said product. In industry we find dosing and packing machines, but most of them base their measurement principle on volume, making the machine only functional with a single product. In addition to this, this type of machinery is expensive and it is impossible to acquire it by a small company or neighborhood store. For this reason, a multifunctional machine was developed for the packaging and sealing of vegetables that uses weight as the principle of measurement, thus opening the possibility of dosing more than one product in the same machine. In this case there is a hopper with three compartments for three different products, which is controlled remotely from a mobile application. A PID control was implemented which is in charge of closing the dosing gate as the weight desired by the user is reached. The end user is delivered their desired product, weighed, packed and sealed. And through the mobile application the production order is created and through a SCADA the status of the order made by the machine is shown. The implemented prototype streamlines the process of weighing and packaging legumes and gives the user the possibility of choosing between 3 different products to dose. In addition to this, it allows to vary the weight and the amount of packaging that the user wishes. The packed product is hermetically sealed, thus preventing the entry of microorganisms. But, when weighing the product, the weighing system generates a certain error, for this reason there is a tolerance in the weight of the product that is delivered to the end user.
