In the Lek d.d. company tablet pills and capsules are produced from the manufacture of raw materials, to the final product. Throughout the production of pellets, as well as during the changes of series, it is necessary to wash high-tech devices repeatedly. The cleanliness can be achieved manually, but if the devices are larger and the high cleanliness of the device is required, different methods, such as WIP washing systems facilities are used.
In my thesis, I will present the washing process of WIP washing systems facilities. WIP washing requires a certain amount of time as it is carried out in five stages. The timing problem, which is the focus of my thesis, required an analysis of steps in practice and via reports. Its result is a design for an improvement of the software code of the washing device.
My goal was to shorten the time of the washing process without any upgrading of the pre-existing elements or changing them. Lek d.d. agreed to collaborate in my research under the condition that I introduce a solution without any additional financial costs. The solution had to be carried out via programming software. It was also necessary to obtain a lot of other information about the washing devices, processes, etc.
Made solution has saved 15 to 30 minutes during washing process and cleanliness has stayed good enough for production conditions. The final solution did not introduce any addition financial expenses for the company.
