The Crewbots™is an automatic sandwich maker designed to automate the process of preparing sandwiches, including hamburgers. This automated sandwich maker is designed for use in commercial kitchens, including small commercial kitchens, such as fast-food kitchens. The apparatus and method for automatically making sandwiches overcomes the drawbacks and limitations of the prior art. The individual sandwich process can be controlled by a communications interface with a point of sales system. The inventive apparatus and method reduces manpower requirements for restaurants, provides enhanced ingredient control, and improves overall product quality.




Briefly stated, one embodiment of the apparatus is comprised of a controls system, an indexing conveyor system, a scale dispensing system including vibrating hoppers, a bulk sauce metering system, a cartridge metering system, a stainless-steel frame, and a supervisory control system with a display



The scale dispensing system dispenses food materials such as lettuce, onions, and pickles onto a sandwich. The scale dispensing system includes stainless steel vibrating hoppers which are easily removed for cleaning. The scale dispensing system controls the quantity of food ingredients using load cell technology. The bulk sauce metering system dispenses an exact amount of ketchup and mustard on the sandwich. The cartridge metering system dispenses mayonnaise, tartar sauce, or other special sauce on the sandwich.



Advantageously, the features of Crewbots provide for accurate order fulfillment, enhanced food safety, consistent portion control of ingredients, a compact and mobile footprint that allows for numerous installation options, easy maintenance and cleaning, and an overall high level of customer satisfaction.

Crewbots has been presented and demonstrated to McDonald’s and Franke, Inc., but the available market is huge. Crewbots can be presented to many more fast-food restaurants, allowing for major profits.
