Automatización de la línea selladora de envases del producto Propolis en la empresa Nature’s Garden a cargo de Dmit Solutions

Abstract

This project designs and implements an automated system for the sealing process of the propolis product containers, the system was developed due to the high demand in the local market due to the COVID-19 pandemic and the inefficient production method. The objective of the system is to improve product quality, reduce production times and improve the operator's work environment. The automated system is made up of three levels according to the automation pyramid, which are: field equipment, control equipment and supervision equipment. Among the field equipment there is the photoelectric sensor for the detection of the inlet bottles, the inductive sensor for the calibration and correction of the stepper motor of the rotary table, the 5/2-way solenoid valves as pneumatic pre-actuators, the use of of double effect cylinders for clamping and lowering the pneumatic motor, in addition to the stepper motor of the rotary table and the DC motor of the conveyor belt. The Xinje XD3-16RTE Programmable Logic controller (PLC) is the main unit of the process control level since it is in charge of processing the input variables of both sensors, maneuvering equipment to make decisions and generate conditions for the activation of its outputs that are connected to the pre-actuators that transport the work to the actuators of the system. The controller fulfills the function of sending and receiving information to the supervision system. This data exchange is carried out through the MODBUS-RTU protocol using the RS-232 connection interface. The Kinco GL070E Human Machine Interface (HMI) is the undamental element of the supervision system, it facilitates the monitoring and control in real time of the machine in an understandable and ergonomic way for the user. The implementation of the automated bottle sealing system reduces the contamination by human contact of the product, facilitates the work of the operators, increases the quality of the product, increases the production per day, making the most of the plant's resources.
