Project Report On Design of Automated Packaging Machine

 Introduction.
     A Chinese factory currently packages a variety of paper-clips into small boxes. Their means of operation is a group of about twelve women who do the job manually. The women stand around a table and take unfolded paper-clip boxes from a common pile. They proceed to fold the boxes, load one hundred clips into each, and pass them on for shipping. They package an estimated 70,000 boxes of paper-clips every day. There are several types of boxes for several types of paper-clips. The dimensions of each type vary slightly, but they are all of similar shape. The most common dimensions of a folded box are 55 x 38 x 20 millimeters in length, width, and height respectively. The pictures below show one type of box in its partially folded andThe factory would like to increase the speed of packaging and decrease its costs as much as possible. Its current operating cost primarily consists of the salaries of the twelve workers. The factory has requested that we automate their process as much as possible in order to reduce the number of paid workers to the smallest number while maintaining or improving upon the speed of the current operation. Our team will conduct a design of an automated paper-clip packaging machine. The machine will fold the boxes as well as load one hundred paper-clips into each box. From the beginning of our project, we constrained our design with seven task specifications .They are listed below.
1. Machine is to be composed of conventional mechanisms
2. Machine is to open box from initial flat position to open position.
3. Machine is to fold and interlock bottom box tabs.
4. Machine is to neatly load one hundred (+/- 1) paper-clips into each box.
5. Machine is to fold and close top box tabs.
6. Machine is to package boxes of paper-clips as quickly as possible.
7. Machine is to cost less than its performance equal in human workers
The first order of business for our team is to conduct research on box folding in general, existing processes, mechanisms, and folding methods. A clear understanding of the problem and any existing automated folding technology is the first step in developing our conceptual design.
