Experimental examination on the pneumatic lifting method of deformable object

Abstract

Industries such as agriculture and food have used polypropylene bag widely used as it is cheap and easy to find. Fertilizers industry especially needed to use the polypropylene bag that have high protection barrier against the high-level humidity especially we living in Malaysia that have high humidity in the air. By layering the polypropylene bag with another polypropylene bag, the moisture problem can be overcome. The polypropylene bag for fertilizers consists of 2 layers which is the woven polypropylene bag and the clear polypropylene bag. However, when assembling this two-polypropylene bag, worker needed to manually insert the clear polypropylene bag into the woven bag. This increases the time process in production, high labour force needed and also higher cost for mass production. Furthermore, repetitive works can cause strain to the worker and increases the number of errors. To overcome this issue, the automated polypropylene bag assembly system is proposed. For this paper, we only focus on the lifting method of the automated polypropylene bag assembly system. With the used of the automated polypropylene bag assembly system, the repetitive works and labour force can be reduced. This will also give out cleaner and consistent last product.
