| Summary: | 碩士 === 國立彰化師範大學 === 工業教育與技術學系 === 105 === The purpose of this study is to improve the feeding system of the rob-shape automatic packing machine. Present the rob-shape automatic packing machine all use motor to drive four-bar linkage mechanism to achieve automatic feeding, but this feeding system can cause noise, and the process of the operation requires a greater torque to prevent components stuck in the storage box. So the internal mechanism is susceptible to damage by stress influences, and the adjustment is very complicated when renew the damaged components. Based on this disadvantages, first, we draw the three-dimensional figure of the old rod-shape automatic packaging machine feeding system, and use the finite element analysis method for structural analysis to understand the feeding system defects of old rod-shape automatic packaging machine. Finally, we use the feed system of machine tool to replace the four-link mechanism of the old rod-shape automatic packaging machine feeding system to reducing the noise emitted when materials transport, and decrease the damage of internal mechanism torque in order to avoid the disadvantages of often replace components. Combining sheet-metal working, with the motor, lead screw and linear bearings, then tests action of the improved new feeding system to fulfill the design of system.
