Project Description:

The project involved integrating two previous projects into a workstation. The previous projects were built by last years EGR 409, Machine Design II, students. The first machine was a bolt driver and the second was a table device that had a cylinder on the top of it. They are shown in Figure 1.

Figure 1 – Table and Bolt Driver

Design Specifications:

There are 4 stations in the machine. The first is a loading station. Full soda bottles are loaded on the ramp and close a contact switch for presence detection. The second station is a decapping station. The device shown in Figure 1 was retrofitted with an ingenious contraption to take the cap off of the bottle. The next station the table device shown in Figure 2 was retrofitted with a hand device that turns with the aid of a stepper motor and belt driven gears. This station will pour the soda into a glass. The final station is the disposal station. It is an unloading ramp. All of the actions, lights and motors are controlled using a PLC. The actions are described using a state diagram.
