Project 1:Material Transfer Your company is designing a new factory layout for their new products using existing buildings.One part of the manufacturing line transfers material from one building to the next.Unfortunately,there is a one foot difference in height between the adjoining manufacturing lines.Department A has designed a mechanism that will collect the material from the lowest conveyor belt and when the desired weight is reached will dispense the material to a container.Department B has designed a mechanism for the top conveyor that will take the material from the container at the conveyor belt height and transfer the material from the container to the conveyor.For purposes of this project you can assume that the transfer of material on and off a conveyor is instantaneous. Your task is to move the container(filled with material)up one foot perpendicular to the floor from conveyor A to conveyor B and then return to the starting position to repeat the process.You want to transport 24 kg of material between point A and point B as quickly as possible.Please note that with the motors supplied,this may not be accomplished in one step.You will need to determine.based on the motor specification and your transfer machine design what is the best strategy for a quick transport-several trips with small weights or a few trips with larger weights.One constraint imposed by Department A and B is that the chosen weight has to be constant so that they can program their machines accordingly.Your machine must fit within the confines of an imaginary box with dimensions of 300W x 500L x 500H.All machines must fit holding fixtures(clamps)to hold machines in place for testing.Power will be supplied by a 12V DC electric motor through a transmission(belts and power screws). To validate and test your machine,you will set the constant weights into the supplied container and lift and lower it the number of times required for 24 kgs.We will measure the overall time from turning on the switch to start the machine to the machine returning to the original state after the full number of trips.You can NOT do any operation after you start the machine.Try to use mechanical method to count the numbers of your trips.You should be able to set up and take down your prototype in the minimal time,no longer than 2 minutes.For testing purposes,your power transmission system must clamp fit on top of the table and clamp to the edge of a table and lift the specified mass in the container(unless you get permission from the instructors for another testing setup). The weights will be in the container and your device must be able to attach to the connection ring.Note:This is all the information that we have at this time.To simulate a more real design scenario,we will continue to distribute information.Although this may be frustrating,this is normal in the design processes.First,please feel free to ask many questions to help clarify matters.Second,we encourage you to layout your calculations and your drawings on the computer(spreadsheets,CAD system,etc)so you can make changes quickly and easily.
