2024-08-21T11:24:11+07:00

The Plant Passenger Car Radial (PCR) produces radial tires and has a Non-Reinforcing Materials Department with various divisions, including the Ply Bias cutting division. One common issue in the bias cutting process is folded ply scraps, mainly found at the end of the treatment roll. Analysis revealed that the problem resulted from the start-stop operation of the let-off motor, causing the treatment roll to twist and the plies to fold. To address this issue, modifications were made to the let-off motor. An inverter was added to adjust the motor speed according to the ply width, and the PLC program was modified to synchronize the motor speed with the HMI recipe. Through five successful trials, the motor speed was effectively adjusted for different ply sizes, reducing the residual rotation of the treatment roll. Data collected showed that prior to the modification, DBC-3 had 205 kg of folded ply scraps in March 2023. After the modification in May 2023, the folded ply scrap decreased to 138 kg, a reduction of 32.7% compared to March.

Hitanol is a granular chemical that is used as a raw material to make compound bladders. The manufacturing process of compound bladder starts by weighing the chemicals. Before the weighing process, hitanol undergoes an agglomeration or accumulation of particles that causes hitanol to agglomerate and makes it difficult for the operator to weigh. As a result, operator has to do the crushing process so that the hitanol returns to granular form. The crushing process is currently being done manually by hitting the hitanol using iron stick. These problems were a driving force in the design of the hitanol crusher with an electro pneumatic system. The results of the design of the hitanol crusher using a double acting cylinder with a stroke length of 250 mm controlled by electric signal. The air flow in the pneumatik cylinder is controlled by a 5/2 single coil solenoid valve that triggered by timer and relay.
