ANALYSIS OF OVERALL EQUIPMENT EFFECTIVENESS (OEE) VALUE TO IMPROVE THE EFFECTIVENESS OF FLEXOGRAPHIC PRINTING MACHINE AT PT X

Abstract

1. Investigation and observation of the F5 machine revealed four problems as the main contributors to the high frequency of brief pauses, including Based on information about production-related damage, the operator changes the plate or screen. The damage brought on by the plate's or screen's end is not identified by the operator team in order to carry out replacement against the plate, resulting in improper monitoring of the plate's service life. Less precise and in-depth visual management information is provided for task instructions. The directions provided are not particular to the manual's mentioned settings. The instruction manual stated that using a pressure handle, the process of decreasing the plate position was to be done gradually. Setting the distance crossbar and master register after that is not recommended. When the cross bars are not appropriate, one of the elements contributing to the miss register label or not in accordance is the miss tolerance between the cross bars. The anilox pressure is adjusted by the operator. Because the operator is unaware of the obstruction that has occurred in the anilox state, this is what the operator does. 2. Improvements were made to this problem such as Monitoring the service life and remaining plate life by recording the use of the revised F5 machine in the CIMS application, Revision of Visual Management, a manual for using the F5 device. It would be more accurate to provide the information "Lower the plate position slowly using handle pressure" since the adjustment is exclusively targeted at the register plate section. to protect the food from contamination and harm, by altering the ideal crossbar distance setting in accordance with the outcomes of the trials, the Work Instructions for "How to Set Cross Bars on the F5 EMS 410 Machine" have been

50 revised. The ideal setting is obtained from the third of the numerous trials, which has a maximum tolerance of 0.75 mm and a speed of 10 mt/min and previously, the operator would set the anilox pressure at 6 bar, which is now the normal value. The recommended pressure is 4 bar, according to the instructions. Then adjustments are made to these parameters for the best printing outcomes and to guard against anilox damage, as too-high anilox pressure can cause the anilox to corrode and leak. There was a decrease in the frequency of labels concerning pareto problems, which decreased from 728 incidents to 90 incidents. Even though the Pareto problem has been overcome, there are still minor stops that still occur on the F5 machine, namely UV shutter errors, tooling, PPIC/warehouse and INK. For the average achievement of Performance Rate (PR) before repair, namely 46,06%, after improvement to 91.55%. By increasing the value of the OEE supporting aspects, it has an impact on the OEE value, which rises to 53,45%. Even though at the same time there was an increase in the Availability Rate due to the alignment of the company's policies and also the quality improvement carried out by the QC team to increase the Quality Rate. Performance Rate remains a major problem and provides the biggest contribution to the OEE value.
