Evaluación del rendimiento y desperdicio de lámina referencia Diana 500 g para el empaquetado automático en Diana Corporación S.A.S planta Yopal año 2022.

Abstract

This project is directed to the evaluation of the yield and waste of the Diana 500g reference sheet for the automatic packaging process in Diana Corporación S.A.S, which causes monetary losses due to the waste generated in the packaging machines. For the development of the project, three specific objectives were worked on: firstly, to characterize the waste generated in the packaging machines and the losses that it generates, to diagnose the performance of the sheet taking into account the different suppliers, and finally to define potential proposals. to decrease foil waste and increase yield. By characterizing the waste generated in the packaging machines, it will be possible to obtain relevant data such as the processed rice reference, the machine in which it is packaged, the sheet supplier used, the weight of the roll, the waste, the cause of the waste of sheet, the final accountant of the machine and the responsible operator, with the use of a Pareto diagram it was possible to define that 80% of the waste is generated by 4 main causes: failure in the vertical seal with 21.8%, failure in horizontal seal with 18.8%, initial adjustment of the machine with 18.2% and sticking of the new roll with 17.9%, the data collection was done during 36 days, with a total of approximately 180 hours, taking into account Note that the price per kilogram of sheet is 16,065, the waste generated in those hours was 44.95 kg, which means $722,221,996, thanks to SAP data it was possible to show that the waste for the month of September was $3,834 .114 and the one for the month of October was d and $2,783,857. Secondly, an analysis of the yield percentage of the sheet was carried out, with the help of the unit weight of the packaging of each finished product, arranged by the company, Excel formulas were applied to the data that related the weight of the roll with the weight unit of the packaging, to obtain the units that theoretically should be produced, also, the weight of the waste generated with the unit weight of the packaging, to know how many units would be produced with the wasted sheet, and finally the yield percentage was obtained with the sum of the final counter of the machine plus the theoretical units of waste, over the theoretical units. Concluding that the average yield percentage of the sheet is 0.9153, the packaging machine that represents the highest percentage of yield is number 11 with an average of 0.95 and the lowest is machine 8 with an average of 0, 87, on the other hand, the supplier Plastilene represents the highest performance percentage, Flexospring maintains percentages close to 100% but there are also very low points and Litoplas remains average. Finally, proposals were defined to reduce sheet waste, which include the objectives of the plan, the steps to execute it and the expected results.
