碩士 === 國立臺灣海洋大學 === 機械與機電工程學系 === 102 === This study is mainly focus on improving the liquid filling frequency of the TKL-1000 HIBAR high speed automatic filling and packing machine. Operation data shows the liquid filling frequency from the TKL-1000 HIBAR high speed automatic filling and packing machine is 135 times per minute, but the maximum operation of liquid filling frequency is 90 times per minute stipulated by HIBAR manufacturer. This data shows that this filling and packing machine is operating under overload situation and easily reducing its operation life that it may cause higher possibility of replacement of spare parts or equipment. Hence, it is necessary to improve and reduce the liquid filling frequency for the TKL-1000 HIBAR high speed automatic filling and packing machine by the means of using the parallel HIBAR pump on the machine in order to reduce high liquid filling frequency into normal condition to maintain production efficiency on line. There are two design steps in this study. Firstly, the design boundary of liquid transfer piping connected to this two parallel HIBAR pumps on the filling machine was changed to a round bend pipe radius in 30mm、60mm、90mm, and the two bended pumps’ piping connection positions were located before the parallel HIBAR pumps , on parallel HIBAR pumps and after parallel HIBAR pumps in order to obtain the design data of flow distribution. The CFD FLOW-3D analysis software was applied to simulate the oil flow distribution on the design piping boundary condition in order to get the numerical result of flow distribution. Subsequently, the Taguchi method was applied to find the design parameter of flow distribution, and then the ANOVA method was applied for optimizing the design parameter of flow distribution as a final goal for improving the parallel HIBAR pumps on the filling machine. Secondly, we redesign the boundary condition of connection pipes into the two parallel HIBAR pumps for optimization design of oil flow distribution according to optimization analysis results previously. The scope of design change may involve the changes of pumps location and connection, and the adjustments of pumps’ input and output signals. As a results shows on this study, the best oil flow efficiency was located on the condition of round bend pipe radius in 90mm before parallel HIBAR pumps in TKL-1000 HIBAR high speed automatic filling and packing machine. It increases the oil filling rate up to the frequency of 180 times per minute by the two parallel HIBAR pumps which higher than 135 times per minute by the one original HIBAR pump, and promote to the filling efficiency up to 33%. For this new design oil filling system, it not only to reduces the oil filling frequency from 135 times per minute to 90 times per minute by one original HIBAR pump, but also to increases the reliability of pump’s life in use and promote the production capability with advancing technology in this field.
