Ag Leader Technology

Team ASAP

As many combine manufacturers go to folding grain tanks to increase holding capacity, an issue with fixed GPS receivers has been created. Ag Leader Technology presented Team ASAP with the task of developing a mounting solution for their ParaDyme receiver. This solution would allow the receiver to fold down with the grain tank and not leave the ParaDyme as the tallest point on the combine.

Team ASAP’s first step was to collect data on the height of grain tanks as well as the dimensions of combine cabs. The team also came up with four designs and a rating matrix to decide which design was the best solution to meet the criteria provided by the client. After a design was chosen, drawings were created and prototype construction began.

After Team ASAP created the prototype, testing was completed at the Ag Leader training facilities. This was done using a Kubota RTV simulating a combine driving through the field. The testing was used to make sure that the prototype design meets all of the design criteria and surpasses expectations set by the client.

After testing was completed, Team ASAP assessed the design and prototype to determine what changes needed to be made. The results from these tests were implemented into a final recommendation given to Ag Leader. After Ag Leader reviews the recommendation and design, they will make the

final decision whether to pursue the project further.

AGCO Corporation

Jackson Connection

AGCO Corp has asked the Jackson Connec on to focus on the problem when assembling the front and rear components of the MT900 ar culated tractor. Problems with the assembly process are: the process is not repeatable, operator ergonomics are unsa sfactory, rear assembly alignment, and ar cula on joint pin placement.  

AGCO has dealt with this problem for six years trying two different methods, neither has been favorable. AGCO manufactures one of these models per day during  mes of high demand. This process requires two operators; ideally it could be performed with one. This process is not repeatable and varies in assembly  me. The variance in assembly  me is a cause for slowing produc on of machines produced on the same manufacturing line demanded in higher numbers. 

Two different data sets were collected and evaluated. The first data collected revealed that the pin being used for the ar cula on joint was not the problem in the process. The second data set collected confirmed that securing the pin into place and lining the up the ar cula on joint accounted for 67.78% of the total assembly  me. Using our data we determined solu ons need to provide repeatability to the process, reduce the task to a single operator, and for the operator to experience no addi onal physical strain. We then used our success criteria, data collected, and part drawings of the machines to formulate five individual solu ons to be designed and evaluated for a final solu on suitability ra ng given by the manufacturing engineers at AGCO.  

The solu ons designed and drawn by our group were evaluated by the manufacturing engineers at AGCO. It was decided that a combina on of three out of the five solu ons designed by our group meet our success criteria. These solu ons have been designed and are ready to be built as prototypes for tes ng by our client.  

Our goal for Bob Harris Enterprises (BHE) was to develop a shock selection process that they can incorporate into their business

structure. BHE is a family run business that focuses on the customization of shocks for dirt track racing. The shock selection process we developed includes a visual brochure for BHE to hand

out to their customers as well as a program that was created using VBA in excel. The program allows BHE a simple method to select criteria specific to the customer’s needs and will then present the shock or shock bundles recommended for the racer. These tools

will support BHE with their sales and allow them to determine a fast efficient analysis of the shock their customer requires.

EFCO

Team Hole Hog

Team Hole Hog’s client for the senior capstone project was EFCO manufacturing in Des Moines, Iowa. EFCO sells concrete forms for construction projects. These forms have been used both globally and locally in projects ranging from the new World Trade Center to the new CyRide expansion project.

The Hole Hog machine is a multi-spindle drill press that simultaneously drills 4-8 holes into a pipe. The Hole Hog has presented EFCO with many issues during the drilling process, including defective products, excessive downtime, and loss of revenue.

Team Hole Hog was tasked by EFCO to find a way to solve the drilling issues presented by the Hole Hog. The group has collected and analyzed data on the production of the pipe braces. Using this data, Team Hole Hog has examined potential options for resolving the problems with the machine. Team Hole Hog has utilized many conventional evaluation methods for identifying issues in quality and production management. These evaluation methods led the team to believe the issues with the Hole Hog are more human-oriented and less machine-oriented. Team Hole Hog is planning on recommending multiple plans of action for EFCO.

Our plan is to create a method for EFCO to measure their equipment effectiveness. Limited collected information has held our own evaluations back, and having a standard collection process will help mitigate issues in the manufacturing process. Implementing a scheduled maintenance procedure will also help avert issues before they cost EFCO time and resources.

Team Hole Hog believes gathering this information will allow EFCO to determine if purchasing a replacement for the Hole Hog is necessary. In the meantime, the information to be presented to EFCO should help them address some of the problems being caused in the production process, as well as give EFCO a way to evaluate potential replacement options for the Hole Hog machine.

Land Plane

This project describes the development of a land plane to be used on a John Deere X700 series lawn tractor. The land plane will be used to grade and level gravel driveways. The land plane is designed to be more efficient than a conventional belly mounted grader blade when used in grading and leveling.

The justification for this project is that current blade attachments are based on a short wheel base tractor and do not allow material to be cut efficiently from high spots in a driveway. Additionally, a conventional blade attachment does not float independent of the tractor axis, so a high number of passes are required to complete the job.

The results of our project include:

Computer model of the land plane design Cost analysis of the design Calculations of force applied to the design Stress test of individual components within the design

We used a computer model of a land plane so it can be easily adapted or changed and can be rapidly developed compared to a prototype. The cost analysis was used to determine if the project would be within our cost constraints. Force calculations were performed to determine the amount of force applied to the blade when in use. The calculated force was applied in the stress tests which analyzed the durability of our design.

Kreg Tool - Huxley, Iowa

Team Kreg

Our group focused on a project that dealt with Kreg Tool, located in Huxley, Iowa. Kreg Tool is well known for their jig products, but they also package and distribute many hardware products, such as screws in the case of our project. Their screw counting and packaging machine needed an increase in capacity of 20% in order to keep up with their customer demand. Our group was to either improve the current packaging process, or develop a new system that would increase the packaging capacity and/or save the company money.

We spoke with Ms. Jackie Baughman, a lecturer in lean manufacturing, in order to help with the efficiency and performance of Kreg Tool’s current counting and packaging process. Our group then turned to Alan Gaul, a specialist in seed-counting machines, in order to assist our group in the research of new machines and the new technologies that are used in the industry. Our group, along with the help of these sources, were able to determine that the accuracy that the current machine counting at can be adjusted to help save the company money. If this money is saved over a span of a few years, it can be used to purchase a new screw-packaging machine that will help the company reach its goal of a capacity increase of 20%.

During the process of our project, our group used an overall equipment effectiveness equation to determine that Kreg Tool’s current screw-packaging machine was performing as well as it could, and still not meeting the customer demand. We were then researched some machines that would help meet the capacity goal, and we also provided a way for the company to save enough money to afford these new machines. With these new machines, Kreg Tool will be ale to continue to grow as a company, and be able to provide for their customers in an effective manner.

Iowa State University Bookstore needs a new process to improve the overall efficiency of separating the security tags used inside books to deter shoplifting. The current process involves employees cutting each sheet of tags by hand with a utility knife, which is time consuming, dangerous, and inaccurate. The bookstore cuts apart 12,000 security tags each semester to be inserted into shrink wrapped books. They need to be cut by hand because the manufacturer does not sell them pre-separated in the United States. A solution to the problem is to create a cutting device. The process will be more safe and efficient by reducing the time spent to cut the sheets. Our group has built a fixture to hold one sheet of Sensormatic tags and it will cut the sheet in two simple motions. The blades on the fixture are fully enclosed eliminating contact with the operator.

In our testing, we expect to see a fifty percent reduction in the amount of time it takes to cut one sheet. We plan on cutting as many sheets of the security tags as we are provided. Estimation to cut 5,000 tags is one hour. We will look at how reliable our device is when the cuts are being made and if any adjustments are necessary. This should help estimate a life cycle and a maintenance interval of the device. The significance of the testing results will determine if this device will be safe for all operators to use, and will cut consistently every time without machine failure.

Our end goal is to present a demonstration of our prototype to our client and make sure they are trained on how to operate and maintain the device.
