Diseño e implementación de un prototipo de máquina controlada por un sistema automatizado para la reutilización de desechos en las madereras

Abstract

In the present project, the design and implementation of a prototype of a machine controlled by an automated system for the reuse of waste in lumber mills was carried out. This prototype has a set of 3 machines, which are divided into: Mill, Dryer on conveyor and mixer. These machines represent the process, based on the industrial area where the MDF chipboard is made. Sawdust is the main participant in the whole process of this prototype, which comes from the waste generated by cutting and planing in the Sandrita lumber mill. This waste is collected and placed in the hopper of the mill machine, which transforms the physical characteristics of the sawdust, followed by the heat of the resistors to remove the moisture from the waste, thus taking advantage of its full potential. Finally, it is transported to the mixing stage, where all the material is compacted with a resin, thus generating a solid block of wood. To achieve that the whole process is fulfilled, the control is used by means of a PLC logo, the same controller is capable of driving each machine in the process, which was programmed using ladder diagram. The electrical design process was carried out in the Cade Simu application, the same application validated the operation of each connection, in order to apply it to the control panel.
