    Diseño y construcción de una máquina pegadora de plantas a compresión neumática con capacidad de 120 pares/dia en la microempresa “Tecnimaquinarias Lalaleo

    The present technical and investigative project was carried out in the "Tecnimaquinarias Lalaleo" microenterprise, located in the city of Ambato - Cunchibamba, Panamericana Norte Avenue, exit to Quito, which was carried out with the objective of developing a machine that helps the craftsmen in their footwear manufacturing process, specifically with the gluing of the soles or soles in the shoes by pressure inside a chamber, for this the determination of parameters necessary for the design was made as the temperature of activation of the glues, pressure and time required for gluing. A design was proposed based on a closed chamber with a membrane inside that uniformly wraps the shoe, obtaining a bond on the entire surface of the shoe sole, which implied the calculation and determination of all the structural elements and selection of some materials and constituent elements of the machine. In the start-up and bonding tests, the results of the use of this equipment within the production process were evidenced, reducing times and obtaining a better bonding and giving a better quality to the final product, being this a direct benefit for the artisan producers that perform this task manually.

    Análisis de los parámetros de prensado en una máquina pegadora de compresión neumática modelo PZAP con capacidad de 120 pares/dia, para mejorar la calidad de adhesión de suelas en la microempresa “Talleres Lalaleo
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánica, 2018) Lalaleo Tenelema, Christian Vinicio; Cabrera Anda, Santiago Paúl
    In the present experimental work, the analysis of the pressing parameters in a pneumatic compression machine was carried out. The parameters that were taken account were pressure, time, material, additive and temperature, a digital thermometer was used to measure the temperature of the sole at the exit of the oven, tests were carried out on gluing with different types of sole "AIR , NICOLE, JORDAN ", the tests in the DIGMIZER software were analyzed in order to find defects or products of low quality, which was considered as a defect to the products that exceed the arithmetic mean of each one of the sheets of consideration, through Graphs of Pressure vs Products of low, could be found find the total number of defects that later served us to determine pressures and adequate times of pressing in addition we qualify a table of quality which gave us to appreciate that quality had each type of footwear being so for AIR sole a pressure of 67 PSI and times of 6 to 12 seconds, acceptable and good qualities, for sole NICOLE a pressure of 80 PSI and times of 6 to 1 2 seconds, acceptable qualities and for JORDAN sole a pressure of 54 PSI and times of 8 to 12 seconds, acceptable and good qualities. The energy consumption of the pneumatic compression machine was analyzed giving us results when pressing the NICOLE sole, at a pressure of 80 PSI and a time of 12 seconds there is a higher energy consumption being 0.2720 Dollars / hour, the lower energy consumption we have when pressing the AIR sole, at a pressure of 67 PSI and a time of 6 seconds the consumption was 0.1358 Dollars / hour.
