Implementación de un prototipo de llenado de jabas con envases basado en un transporte por cremallera con una interfaz hombre máquina.

Abstract

A system of filling crates with containers based on a rack transport with a human machine interface was designed and implemented; the prototype presents a new way to transport the several types of elements within a process taking into account that this does not exceed the engine torque. The prototype has as objective to observe the flexibility that the rack transport presents with respect to the traditional transports like the conveyor belts or the ones assisted by air. Its design has 18 stepper motors with their respective gears of 28 teeth, the same that fits with the teeth of the straight rack producing the sliding of this in any direction, horizontal, vertical and diagonal. The material used for the construction of the movements made by the motor is generated through the pulse emitted by the programmable logic controller (PLC) and are received by the control board where the Arduino Mega 2560 is connected to the drivers and finally to the motors, in this way the trajectory carried by the crates with packages towards the filler was programmed. In the tests, the prototype demonstrated a flexibility of 100% with respect to the conveyor belts because the rack transport allows to move in any direction without complications, in an easy and efficient way, producing a volume increase in the filling of containers. It is recommended to take into account that the meter is balanced, the speed at which it works should not exceed 20revolutions per minute (RPM), in addition it has to be considered the alignment of the gears of engines.
