Leonardo the pizza cutter is a Zume invention patented in US20180071939A1, titled Systems and method related to a food-item cutter and associated cover.
This invention resolves the pervasive problem of having to use a clean knife to cut food, notably when the knife is cutting different pizza pies produced on a cobotic assembly line. Thus, the invention recites, in particular, a plurality of radially assembled metal blades, extending from a central axis, together with their radially assembled silicone wipers. The blades are extendable and retractable, piston-activated and motorized. Each blade extends and retracts between the gap formed by two triangular plates, perpendicular to the blade, radially positioned, attached with brackets to a frame, and between which a pair of opposing wipers are detachably assembled. The wipers are assembled in a “V” shape, relative to the blade in extended (Fig. 14), or retracted (Fig. 15 ) positions.
The cutter assembly is further supported by a frame and a cover. The base of the cover consists of a drawer, equipped with a back wall, designed to activate a sensor when the drawer is closed. The drawer translates between three positions: open, closed and cutting when the drawer is aligned with the blades. A handle on the drawer may include an ON and OFF switch for user-activated cutting. An override switch is included on the cover, which in the ON position prevents the blades from extending. A display on the cover may provide such information as the pressure applied in the cutting and the number of times the blade has extended, relative to the last time the blades were cleaned.
The abstract of this invention is included below, together with Figure 1 of the patent showing an isometric view of the mechanical cutter assembly, according to one embodiment of the invention.
Systems and methods are disclosed for cutting a food item when preparing it to be served to a customer. In some implementations, the cutting system may include a cover that may be used to at least partially surround a portion of the cutting system. The cover may include one or more doors, drawers, or other movable components that may be used to engage the cutting assembly of the cutting system by activating one or more sensors located along or proximate to the path traveled by the movable component. The movable component may activate the sensor when the movable component has appropriately positioned the food item under the cutting assembly to be cut. Additionally, the cover may include one or more user-engageable switches that may be used to selectively engage cutting assembly when the movable component of the cover is appropriately positioned to be cut by the cutting assembly.
