Application of six sigma technique on vials washing process

Abstract

In the proposed research work firstly Six Sigma technique was applied for decreasing the vials breaking during washing process by high speed rotator vials washing machine (Ambica ARVW-120) with washing rate of 60 vials per minute. The problems defined by the supervisor of the process that the breaking of vials during washing process. After the long observation of the process various parameters as mentioned below were analyzed (vials breaking). when vials enters from the turn table to the in feed worm then at this stage the point comes where the vials have to turn in inverted position at the hard surface, if the intensity of dropping or turning of the vials at surface is high then it causes breaking of vials, and those vials having bubble on their neck, have more chances to break. Second reason, when vials enters in the washing area through in-feed worm, then supporting plate (which is attached with rubber) is responsible for proper placement of vials from in feed worm to the gripper. Due to this the plate, vials easily fixed. through neck on the star wheel. During this process the elasticity of the rubber belt reduces with time and due to this the supporting plate may not able to place the vials to the gripper properly and if vials do not placed to the gripper then it falls down to the stainless steel plate in the washing area and broke.
