Debaler Instrumentation and Data collection

The goal of the project is to build upon and add to the previous debaler prototype from 2019-2020 school year. We will achieve this by making the debaling process automated by adding an inlet conveyor system capable of carrying 2 bales towards the debaling head, while also integrating a working control system to control the material outflow and will also be able to detect bale jamming/motor stall and correct with no human interaction. By the end our project the debaler should be able to have a bale successfully debaled at a consistent flow for a specified flowrate without any human input other than the loading of the bale.

=Problem Definition= The current debaler prototype is not an automated process, and the main goal from the client is to make the current prototype an automated machine. This requires adding some type of infeed conveyor to the current processing head, a working control algorithm to detect bale jams, and chute clogs also need to be added to this system. Additional improvements to the prototype such as cleaning off the processing head and making sure all loose (debaled) material goes through the chute are also desired by the client. Testing and data analysis of the system running different types of materials is also required.

Background
As the need for precision agriculturally based feedstocks for biofuels and bio-based products increases, there is a need to debale straw, corn stover, hemp stalks, and other baled herbaceous crops for feeding into industrial processing equipment. The fundamental question is how can we effectively and efficiently turn baled material back into the loose material it was baled from and feed it onto a conveyor for subsequent milling and processing? Existing debalers were developed to support dairies and feedlots where the objective is only to distribute the material in small enough “chunks'' for cows and other animals to eat. Existing methods either do not break apart the flakes well or create a large amount of fines in the process. Forest Concepts needs a debaling mechanism to break down large square bales of stover, switchgrass, and similar materials into uniform streams that can be conveyed into our Crumbler® rotary shear comminution systems.
