Abstract

Programmable logic control (PLC) is widely used for machine of component control systems in the automotive, aviation, food processing and other industries. PLC sets the component motion system with programming language using ladder program. Using of ladder program on the system motion of the machine of component has some advantages such as more simple, easy, flexible and can be changed quickly. PLC in this paper is used to set the motion system and sensor components on the drying process of rubber. The components to be driven are motors, temperature sensors, dry detection sensors and color from dry rubber content form. Type of PLC used is Smart Relay Zelio type. The PLC regulates the movement of wet rubber in and out in the form of dry rubber. Changes in dry rubber content are adjusted by set of the temperature in the drying chamber. Drying system uses greenhouse effect by making hanger dryer design in the form of line path. In this paper focused on motion control system motors and sensors of dry rubber. The results obtained the control system can work in accordance with the control input given and the time required to dry the rubber with the dimensions of 100 x 50 mm from the initial temperature of 32 0C to the final temperature of 70.20C is 109 minutes and 766 w electric power. The water content and weight of the rubber were 10.5% and 30 grams while the initial condition of wet rubber was 18.5% for moisture content and weight of 45 grams.
