Diseño y Automatización de una Máquina Ensacadora de Cal Utilizando un PLC para la Empresa Calizas del Chavo.

Abstract

It was designed and automated a bagging machine of lime, using a programmable logic controller (PLC) for the company “Calizas El Chavo”, due to the necessity to implement an automated process in the bagging machine of the hydrated lime and thus optimize the production of the company. The information gathering was the observation of lime processing plant; doing the review of various documents, books and web pages. In addition, trial and error was used to determine the final positioning of the elements components of the machine and the work sequence programing. For the implementation and automation of the process of bagging machine, line used metal plates and profiles for the structure two magnetic sensors for pneumatic cylinders of dosage and adjustment positioning, control of weighing is performed throngh cells change and a conditioner of signal and the process general is responsible for a PLC (programmable logic controller) Twido TWDLCDA16DRF, also in the control panel make a start/stop button a weight switch, emergency stop and lights LED (light emitting diode) that indicate the status of the process between the actuators used relays and double effect pneumatic cylinders controlled by a block of solenoid valves for the electrical connections we used 18 AWG cable and pneumatic connections for hoses and fittings. After the implementation and completion of respective calculations obtained a 10.37 aquare chi which is greater than the theoretical chi square of 9.49, this is why it is accepted the hypothesis. Thus, it is concluded that the implementation of this machine serves for the limestone industry carried out processes of bagging machine more effectively and in the shortest time possible, resulting in a significant improvement in the production process. We recommend to the workers of the company “Calizas el Chavo” to make use for the user’s manual, as well as the technical specifications and features of each component of the module, for proper operation.
