The goal of this project is to improve on a current tote extractor design. By doing this, grid efficiency can be improved as well as the footprint of the current automated extraction system will be reduced.
Currently, Bastian Solutions has an automated shuttle extraction system with the extractor mounted in the center of the shuttle. This design takes up a significant amount of space and can be improved upon.
Study and prototype a cantilever tote extraction system to reliably pick and place storage totes with prescribed speed and accuracy. The solution will also involve engineered features for interfacing with the with the existing tote bin design.
- Prototype capable of engaging tote
- Prototype capable of removing tote
- Shuttle must be able to travel while carrying tote
- Prototype capable of replacing tote
- Build model of shelf and tote for testing
- Improve current grid space footprint
|Height Limit (Shuttle Base)||25 inches|
|Width Limit (Folded Position)||30 inches|
|Length Limit||30 inches|
|System Weight Limit||40 pounds|
|Extraction Time||3 seconds|
|Voltage Requirement||48 VDC|
|Durability||20-30kh of operation without maintenance|
Shelf model has been built in order to properly prototype extraction mechanism.
Final Extractor Design
The final design will use two gears actuated by two pinion gears mounted on a shaft driven by a stepper motor to fold up the extraction tray. The extraction tray will slide out either end 2 inches when in the down position to reach the totes in the storage grid, this motion is driven by a lead screw motor. The tote will be pulled onto the tray by a arm attached to a chain driven by a stepper motor.
