Diseño de una máquina dosificadora semiautomática de chocolates y trufas por peso

Abstract

This Degree Project presents the design and simulation of the prototype of a chocolate dosing machine with a capacity of 20 kg, for the packaging of a 150-gr assorted chocolate bag, known as "Chocolerito". In Chapter I, the background, the problem statement, the justification, and the general and specific objectives are made up, where it is detailed about the automation that the chocolate dosing process is to be carried out to optimize the time and obtain the right weight. that is desired in the cover of the "Chocolerito". In addition, the theoretical framework is described where the engineering concepts and principles for the development of the machine are developed. Chapter II describes a series of alternatives for the automation of the dosage of chocolates, where the most optimal and feasible one was chosen based on specific characteristics that are considered important to carry out the prototype. In Chapter III the calculations are presented regarding each of the components of the dosing machine (hoppers, conveyor belts), the electrical and power circuits and the plans of the machine for the Salinerito company, since the dosing of 4 types of chocolates: 12 gr truffle, 10 gr Frei, 8 gr medium chocolate, 5 gr small chocolate in a 150-gr case containing all featured chocolates. For this, each one of the chocolates is weighed and the volume is obtained experimentally to make the exact calculations of the hopper and the conveyor belt. Thus, 150 grams of chocolates are obtained from the dosing machine, where 4 units of truffles, 4 units of Frei, 4 units of medium chocolate and 6 units of small chocolate are placed, making the correct dosage of the chocolates with a tolerance of ±1. Chapter IV details the results obtained, the final design of the dosing machine and the feasible economic analysis, according to which the project is viable.
