Modifikasi Push Roll Wind Up Menggunakan Sistem Pneumatic Pada Mesin Jointless Pt. Xyz

Abstrak

At the PCR plant there are 3 machines that produce jointless, including DS-LJL1, DSL-JL2 and DSL-JL3. However, the DSL-JL1 machine produces fewer products than the DSL-JL2 and DSL-JL3, because the winding process is still done manually by moving the jointless rolls one by one by the operator which can affect the cycle time in the wind up process.Engine modification is one way to increase the capacity of the DSL-JL1 engine. The system in the winding process is changed to semi-automatic, this process can shorten the processing time when winding up.The result of this research is to modify the DSL-JL1 engine by adding a pneumatic system called push roll to the winding process. The jointless rolls that have been winded will be driven by a cylinder attached to each winding, so that the jointless rolls can be moved simultaneously, by changing the manual system to semi-automatic. Before installing the push roll, the average winding time was ± 47 minutes and after the push roll was installed it dropped to an average of ± 41 minutes for every 1 time winding process. Thus shortening the wind up time 7 minutes faster than before, DSL-JL 1 experienced an increase in production capacity of roll jointless reaching 11%.
