Hi fellow engineers, As part of our "smart factory" policy, our company decided to change all our inventory cabinet to use vertical carousel cabinets, where items would automatically rotate to an opening and operators would easily press a button to get items that they need. My design is very similar with this design http://www.jtechcom.com/samples/vertical.pdf I am in charge of the design, and being an automation designer, I have found many obstacles in the mechanism of the system. I am wondering if anyone has ever worked on this before. The system consists of an AC motor that turns the drive assembly which then turns the load chains. The load chains are connected to the shelves with scissor arms and a stabilizer arm, much of which images you can see on the link above. I have drawn most the design on solidworks, but I cant see a place to attach pictures here, is there anywhere I can attach screenshots of my drawings? Problem statement: The scissor arm and stabilizer tracks on which the stabilizer arm is moving along its path looks like it needs to be on a precise radius in order to make the shelves turn without tilting or hitting each other. Does anyone know any such calculations or mechanical requirements for this path?
