Developing Servo Indexing System Using Timing Screw for Automatic Liquid Filler in Manufacturing Environment

In the world of automation, one the most significant topics for industrial manufacturing technology is primary packaging of products and machine design which can be considered as the integral part of new products development process. Servo motion control is one of the most promising solutions for primary packaging industries. This research article will present a servomotor driven indexing system using timing screw in a filling machine which can be described as an efficient application of precise motion controls. In addition, the research is focused on the Integration of the indexer with an automatic liquid filling machine developed from industrial prospective. It also emphasizes on more advanced features of an indexing system of a generic filling machine. The servomotor driven indexing system using timing screw offers the premium method to index containers or bottles in order to design a fast and efficient production in an automatic liquid filling system. Servo encoder feedback can provide the closed loop control on the process and save the product from wastage with the help of a feedback signal. Nevertheless, this type of indexing system can offer cost benefits and a high degree of precision. The idea presented here is of an automatic filling system relates to the indexing method of different types of containers and more particularly to an electromechanical control system and method for controlling servomotors that are a part of an indexer of the filling machinery. This type of bottle indexing & filling mechanism plays very important role in the medical, beverage and wine industries. These machines are used not only for filling and capping but also to reduce the labor operator or manual operation in the industry. A traditional process contains filling the bottle by hand or by a semiautomatic machine having questionable accuracy will create lots of wastage of filling product. There are several important factors that are necessary to be brought up while discussing about Automatic Liquid Filling system such as the type of liquid, the size of the container, the throughput of the system, filling method etc. The traditional process takes lot of preparation time. This means, first of clean the bottle, second, determine whether the bottle is crack or not. In this way, the work setting time is more as compared with the filling time of the bottle. So due to this problem the idle time of the process is more as compared to the working time of the machine this will results in the low productivity of the machine and also it requires many worker for this process. This affects the overall efficiency of the machine. In turn this also reduces the throughput due to the more idling time. The goal of this research was to achieve the design, testing, and implementing an entire working machine in a shortest possible time. Thus, machine design and controls programming including engineering method was implemented from conception through the completion.
