Resumen
El objetivo de este trabajo es optimizar la distribución del proceso en el Área de Empaquetado para lograr comercializar un mejor producto terminado, otorgando a la empresa mayores utilidades.
Se detectaron problemas como: Producto desperdiciado, Fallas en el proceso por parte de la primera transportadora y Producto mal terminado, además de encontrarse un Cuello de Botella (limitación del sistema) en el esta área. Se describen sus causas con el diagrama de ISHIKAWA y se registran cuantitativamente en el Diagrama de PARETO.
Se elaboraron Diagramas Hombre-Máquina para cada transportadora; registrando un 77,72% del tiempo programado con problemas, cuantificándolos en $ 21.469,44 al año. Para lo cual se recomienda: mantenimiento en ciertos equipos así como reubicar un operario. Según el cálculo realizado en cada transportadora y por medio del sistema Work Factor se encontraron diferencias enormes en los tiempos que trabaja cada operador, debido a un mal cosido. Por medio de Diagramas Analíticos Propuestos (Cursogramas) se registran ahorros de actividades, además el tiempo usado en efectuarlas. Con la incorporación de estructuras metálicas para sujetar las máquinas de coser, ganchos y barras que sujeten al saco durante su transporte, se pretende brindar mayor eficiencia como seguridad al operario para que, sin ningún problema, realice su trabajo. Asimismo, se sugiere la importación de tres máquinas con el fin de: mejorar la distribución de sacos en cada transportadora y registrar exactamente la producción; además adquirir un intercomunicador para mantener informado a la Bodega de Producto Terminado. También se empleó anexos hechos en Autocad con diseños de los implementos y Proyect con la puesta en marcha de las propuestas, que dan un costo de $ 20.530,07; determinando un Rendimiento sobre la Inversión (RSI) del 30,79 % mensual y siendo, a su vez aceptado por el FDE (Flujo de Efectivo Neto) y también por el Costo Beneficio según los cálculos utilizados.
The aim of this work is to optimize the distribution process in Packaging Area to achieve a better end product market, giving the company greater profits. Problems were detected as: Product wasted, Fallas in the process by the first conveyor and poorly finished, besides being a bottleneck (system limitation) Product in this area. Its causes ISHIKAWA diagram are described and recorded quantitatively in the Pareto diagram. Man-Machine Diagrams for each transporter were developed; registering a 77.72% of the time scheduled with problems, quantifying in $ 21,469.44 a year. Which is recommended for maintenance in certain equipment and relocate an operator. As calculated on each conveyor and through the Work Factor system huge differences in working time each operator due to poor stitching is found. Through Proposed Analytical Diagrams (Cursogramas) savings activities, and the time spent on exercise them are recorded. With the addition of metal structures to hold sewing machines, hooks and bars to clamp the bag during transport, is to provide greater efficiency and safety for the operator, no problem, do their work. Also import three machines in order suggested: improving the distribution of bags in each conveyor and accurately record production; also acquire an intercom to keep informed the Finished Goods Warehouse. Annexes facts was also used in Autocad with designs and implements Project with the implementation of the proposals, giving a cost of $ 20,530.07; I determining a Return on Investment (ROI) of 30.79% per month and being, in turn accepted by the FDE (Net Cash Flow) as well as by the Cost Benefit calculations used.
