Patent Application
20180071939
This disclosure generally relates to technology for a cutting system that cuts and divides food products, and a cover to at least partially surround the cutting system.
Various items are employed to cut food. Typically a knife includes an elongated blade with a sharpened cutting edge. Rotary knifes are typically employed for cutting pizza. The rotary knife is a disk that is rotatably mounted to a handle, and outer circumference of the disk having a sharpened cutting edge.
Sharpened cutting edges of a blade, either elongated or rotary style may be single beveled or double beveled.
Cutting food is typically easier with a clean knife than a soiled knife. Some foods tend to soil a knife more than other foods. For example, slicing a hot pizza often leaves melted cheese stuck to the blade of the knife, making it subsequent use of the knife difficult, and increasing the potential for distributing debris from a first food item to a subsequent food item. In addition, knives and other cutting components have sharp edges that may cause serious injury if mishandled.
An apparatus may be summarized as including: a plurality of blades that extend radially from a central axis, each of the blades having a pair of faces opposed to one another across a thickness of the blade, and each of the blades having a cutting edge; a transmission operable to move the plurality of blades between a retracted position and an extended position; and a plurality of wipers radially arrayed with gaps formed between sequentially adjacent ones of the wipers in the array, each of the blades aligned with a respective one of the gaps, the gaps dimensioned to closely receive the respective blades to physically engage the faces of the blade at least on movement of the plurality of blades toward the retracted position thereof from the extended position thereof.

The headings and Abstract of the Disclosure provided herein are for convenience only and do not interpret the scope or meaning of the embodiments.
The bottom component 102 may include a base 120, which supports a food item during cutting. Typically, the base 120 will carry “consumable” consumable trays 118 on which a food item is carried, for example cooked or partially cooked food items (e.g., par-baked pizza). The consumable tray 118 may advantageously serve as a bottom portion of packaging in which the food item is at least one of cooked, stored, or shipped. In use, a first consumable tray 118 along with a first instance of a food item may be removed after cutting of the food item, and a new consumable tray 118 along with a second instance of a food item placed on the base 120.
The base 120 may have one or more physical registration features which cooperate with complementary physical registration features on the consumable trays 118. As illustrated, the physical registration features may include apertures in a top surface of the base or plate and complementary buttons that extend from a bottom surface of the tray 118. The physical registration features may of course be reversed, with the buttons extending from the base 120 and the recesses in the tray 118. Alternatively, the base 120 may include one or more recesses and one or more notches and the tray 118 may likewise include one or more recesses and one or more notches. Alternatively or additionally, physical registration features other than recesses and notches may be employed. Physical registration features allow rapid alignment, and may even allow automated equipment (e.g., a robot) to quickly and accurately move consumable trays 118 with food items into and out of the cutting system 100. Physical registration features may advantageously prevent movement of the tray 118 during cutting, including translation and/or rotation.
In at least some implementations, the upper assembly 104 includes at least a transmission 112, a cutting assembly 114, and a cleaning assembly 116. As explained in more detail below, the transmission 112 is coupled to cause the cutting assembly 114 to move between an engaged position or configuration and a disengaged position or configuration. As explained in more detail below, the cutting assembly 114 includes a plurality of knifes or blades which cut the food item, at least when in the engaged position or configuration. As explained in more detail below, the cleaning assembly is positioned to engage the knifes or blades of the cutting assembly 114 at least when passing between the engaged position or configuration and the disengaged position or configuration to automatically or autonomously clean the knifes or blades of the cutting assembly 114 on each pass or use.
The frame 110 may be used to secure or hold components of the bottom component 102 and the upper assembly 104 relative to one another, to facilitate the operation of cutting system 100.
In some implementations, the tray 118 includes an upwardly facing circular-shaped food receiving portion 220 which receives the pizza thereon. The tray 118 may further include a raised peripheral rim 204 disposed about a perimeter of the food receiving portion 220. The raised peripheral rim 204 comprises a raised upwardly facing apex surface and a downwardly and outwardly extending sidewall which meets with a substantially planar base flange 222 that extends outwardly from the raised peripheral rim 204. The raised peripheral rim 204 may define the shape and size of the food item to be cut or processed. As shown in
The food receiving portion 220 of the tray 118 includes a planar surface 226 and a number of features which extend at least one of upward or downward from the planar surface 226. In particular, the food receiving portion 220 includes a central well 228 which extends downwardly from the planar surface 226 and receives liquid drippings or condensation from the cooked food (e.g., pizza) placed on the tray 118. In the illustrated implementation, the central well 228 has a circular perimeter, but may have other shapes (e.g., triangle, octagon) in other implementations.
The food receiving portion 220 may also include a plurality of food receiving portion channels or grooves 208 (also referred to herein as “channels”) extending downwardly below the planar surface 226 and running radially outward from the central well 228 and terminating at the raised peripheral rim 204. In some implementations, the radial channels 208 may extend only partially between the central well 228 and the raised peripheral rim 204. In the illustrated implementation, each of the channels 208 has a U-shaped cross-sectional profile, but in other implementations, the channels may have other shapes (e.g., V-shaped). In some implementations, each channel 208 may slope downward from the raised peripheral rim 204 toward the central well 228 to facilitate the flow of liquid through the channel into the central well. Each pair of adjacent channels 208 and a corresponding portion of the raised peripheral rim 204 delineate a respective sector portion 230 of the food receiving portion 220 which supports a portion of a food item (e.g., an individual slice of pizza). In the illustrated implementation, the tray 118 includes eight channels 208 and eight sector portions 230. Generally the tray 118 may include N channels and N sector portions, where N is a positive integer.
The plurality of channels 208 may be equally radially spaced to allow cutting of the food item (e.g., pizza) into equally sized pieces when cutting assembly 114 cuts the food item. The channels 208 may be positionable relative to the cutting assembly 114 such that each channel 208 is positioned to receive a corresponding feature, e.g., a knife or blade as discussed below, from cutting assembly 114 to cut and thereby process the food item. Because the channels 208 extended downward from the planar surface 226, the cutting assembly 114 may cut through the food item over the channels 208 without damaging (e.g., cutting) the food receiving portion 220 of the tray 118. Further, each of the channels 208 is non-parallel with each of the edges 224a-224d of the tray 118, which may improve the rigidity of the base. In the illustrated implementation, each of the channels 208 is offset by 22.5° from perpendicular from a respective one of the edges 224a-224d which the channel extends toward. Further, each of the channels 208 is collinear with an opposite channel that extends radially in the opposite direction. Thus, when the tray 118 is to be discarded (e.g., composted), the user may fold the base along an axis which extends through two opposing collinear channels to reduce the dimensions of the base so the base will fit within a compost receptacle.
Among other things, the channels 208 may function to strengthen the tray 118 in rigidity and provide supporting forces to the food receiving portion 220 when the tray 118 is disposed on a resting surface, such as a countertop, oven or another food container. The channels 208 may also serve as guides for the cutting assembly 114 to cut eight equally sized pieces of a food item (e.g., pizza). Further, the channels 208 may provide air space below the food item, which provides additional insulation. In some implementations, because the channels 208 may be substantially covered by the food item placed on the food receiving portion 220, indicia (e.g., visible and/or tactile markings) may be positioned on or adjacent the raised peripheral rim 204 radially in line with the channels 208 to aid a user in cutting the food item along the channels. Indicia may also be used by detectors in the cutting assembly to confirm that a tray 118 has been properly positioned on the base 120 so that features on the tray 118, such as the channels 208, are properly aligned with corresponding features in the cutting assembly 114.
As discussed above, each pair of adjacent channels 208 and a corresponding portion (e.g., a 45° arc portion) of the raised peripheral rim 204 may delineate a respective sector portion 230 of the food receiving portion 220 which receives an individual piece of the food item (e.g., slice of pizza). Each sector portion 230 includes a portion of the planar surface 226 and a raised sector portion rim 232 which extends upward from the planar surface 226 and adjacent each of the channels 208 which define the sector portion 230. In addition to supporting the food item above the planar surface 226, the raised sector portion rim 232 adjacent the channels 208 may aid in supporting the food item near the cutting location, thereby facilitating the cutting process to provide accurate individual pieces.
Each sector portion 230 further includes a sector well 210 which may receive liquid drippings from the food product therein. In the illustrated implementation, each sector well 210 has a perimeter rim adjacent the planar surface 226 which has an oval profile. In other implementations, each of the perimeter rims may have a profile in the shape of at least one of a circle, a triangle, a square, another shape, or a symbol (e.g., logo). Each sector portion 230 may also include a plurality of raised sector ribs or projections 234 which extend upward from the planar surface 226 around the sector well 210 having an uppermost portion which supports the hot food product (e.g., pizza). In some implementations, the combined area of the raised sector ribs 234 in a sector portion 230 is smaller than the portion of the planar surface 226 in the sector portion. Thus, when the food product is supported on the uppermost portions of the raised sector ribs 234 and the raised sector portion rim 232, heat loss due to conduction through the planar surface 226 is substantially reduced compared to food containers with flat bottom surfaces which have relatively large surface area contact with the bottom surface of the food product. Additionally, the raised sector ribs 234 and the raised sector portion rim 232 tend to isolate the bottom surface of the food product from the planar surface 226, which prevents the food product from becoming soggy due to trapped liquid on the planar surface 226 of the food receiving portion 220.
In the illustrated implementations, the shapes of the raised sector ribs 234 are elongated and have a length dimension which extends radially with respect to the central well 228. Additionally, in the illustrated implementations the raised sector ribs 234 are radially symmetrical. In other implementations, the number, sizes and dimensions of the raised sector ribs 234 may be different from shown in the figures. The raised sector ribs 234 also function to improve the rigidity of the tray 118.
In some implementations, each of a plurality of features of the tray 118 comprising the raised peripheral rim 204, the central well 228, the sector wells 210, the channels 208, and the raised sector ribs 234 is spaced apart from at least one other of the plurality of features by a distance which is less than or equal to one inch. In some implementations, due to the aforementioned plurality of features, the food receiving portion 220 of the tray 118 does not have a continuously planar surface which exceeds 2 inches by 2 inches. Such features may significantly improve the strength of the tray 118, while allowing the base to have a length dimension greater than 12 inches (e.g., 16 inches), a width dimension greater than 12 inches (e.g., 16 inches), an overall height which is less than 1.5 inches (e.g., 1 inch), and a material thickness between 0.5 mm and 1.0 mm (e.g., 0.8 mm). In other implementations, the tray 118 may have a larger height.
The tray 118 may include one or more registration features 206. The registration features 206 may be used to attach the tray 118 to the frame 110. In doing so, the registration features 206 may be used to properly align the tray 118 with other components, such as the cutting assembly 114 in the upper assembly 104. As shown in
In some implementations, at least some of the registration features 206, the central well 228, and the sector wells 210 extend downwardly to a lowermost portion of the tray 118 so that they are weight-bearing and function as “feet” which form an insulating air space below the food receiving portion 220 of the tray 118 and a resting surface when the tray 118 is supported on the resting surface. Thus, the raised sector ribs 234 of each sector portion, together with at least some of the registration features 206, the central well 228, and the sector wells 210, form a layer of air insulation between the planar surface 226 of the food receiving portion 220 and the food product and a layer of air insulation between the food receiving portion 220 and a resting surface using only a single layer of material (i.e., the material which forms the tray 118). Additionally, the aforementioned “feet” raise the remainder of the tray 118 slightly above a resting surface (e.g., table), which causes a shadow to be cast, similar to a more formal serving plate.
The base 120 may have one or more features that are complementary to features in tray 118. For example, as shown in
The base 120 may have perimeter 308 that forms a circumference around the central cavity 306. The perimeter 308 may be complementary to a raised peripheral rim 204 in the tray 118. Accordingly, the perimeter 308 may have an apex and a downwardly and outwardly sloping sidewall that are sized and dimensioned to be slightly smaller than the corresponding apex and downwardly and outwardly sloping sidewall on the raised peripheral rim 204. In this implementation, the perimeter 308 may provide support to the raised peripheral rim 204 when the food item is being cut by cutting system 100.
The base 120 may have a plurality of grooves 310 that extend radially from the central cavity 306 to the perimeter 308. The grooves 310 may be immediately adjacent to two opposing ridges 312. The grooves 310 and ridges 312 in the base 120 may be sized and dimensioned to be complementary to the channels 208 and the raised sector portion rims 232 in the tray 118. Accordingly, the grooves 310 may be slightly larger than a corresponding channel 208, and the ridges 312 may be slightly smaller than a corresponding raised sector portion rim 232. In such an implementation, the grooves 310 and ridges 312 may provide support and stability for the tray 118 when the food item is being cut by the cutting assembly 114.
As previously noted, the upper assembly 104 may comprise the transmission 112, the cutting assembly 114, and the cleaning assembly 116. One or more of these components may be attached or secured to frame 110 relative to each other and relative to the components in the bottom component 102 to allow the cutting system 100 to cut or process food items.
The square base 350 may be positioned below the cutting assembly 114 (
In some implementations, the square base 350 may be attached to the frame 110 using, for example, bolts, screws, or other components. In some implementations, the components used to securely physically couple the square base 350 to the frame 110 may pass through one or more of the registration features 354 to securely engage with a corresponding receptacle on the frame 110. In such implementations, the registration features 354 may be used to align the square base 350 to be appropriately placed on the frame 110. In some implementations, a base may be included as a portion of a single integrated frame 110 and square base 350. Alternatively, in some implementations, the tray 118 may be attached directly to the frame 110 without the need for a square base 350. Hence, the frame 110 may include one or more brackets appropriately placed to provide complementary registration features to the registration features in the tray 118.
The square base 350 may have one or more features that are complementary to features in tray 118. For example, as shown in
The base 150 may include food-receiving perimeter 358 that forms a perimeter around the central cavity 356. The food-receiving perimeter 358 may be complementary to a raised peripheral rim 204 in the tray 118. Accordingly, the food-receiving perimeter 358 may have an apex and a downwardly and outwardly sloping sidewall that are sized and dimensioned to be slightly smaller than the corresponding apex and downwardly and outwardly sloping sidewall on the raised peripheral rim 204. In this implementation, the food-receiving perimeter 358 may provide support to the raised peripheral rim 204 when the food item is being cut by cutting system 100. The square base 350 may have a plurality of grooves 360 that extend that may be sized and dimensioned to be complementary to the channels 208 and the raised sector portion rims 232 in the tray 118.
Actuator 404 may be used to apply a force to the rod 402. The force applied by actuator 404 may move the rod 402 along the central axis 408. In some implementations, actuator 404 may be a pneumatic drive (e.g., piston head and cylinder) that uses compressed air or hydraulic fluid to apply a force to the rod 402. In some implementations, the actuator 404 may be an electric motor with gears or a solenoid that may be coupled (e.g., physically, magnetically) to apply a force to the rod 402. In some implementations, the actuator 404 may be comprised of pneumatic valves and switches that function based on directed air flows. In such a situation, the cutting assembly 114 may be fully pneumatic and may require no electrical connections for operation. In some implementations, the actuator 404 may be started or activated by one or more user engagable input components 124, such as buttons, switches, or other control features. For example, user engagable input components 124 (shown in
The force to be applied by the actuator 404 may depend on the action to be undertaken by the cutting assembly 114. For example, when cutting assembly 114 is being moved into the extended position to cut a pizza, as discussed below, the actuator 404 may apply a force in a downward direction to move the cutting assembly 114. When the cutting assembly 114 is being moved upward into the retracted position, the actuator 404 may apply a force in an upward direction to move the cutting assembly 114.
Each blade 502 may have two faces, 512 and 514, disposed on opposite sides of the blade 502. The two faces 512 and 514 may be separated by a distance that may be equal to a thickness of the blade 502. In some implementations, the blade 502 may include a cutting edge or cutting surface 516 that may be used to cut the food item. Each blade 502 may be made of stainless steel or any other material that may be safe and appropriate for processing and cutting food items and easily sanitized. In some implementations, each of the plurality of blades 502 may be the same length.
A respective bottom-most edge (e.g., cutting edge) of each of the plurality of blades may reside in a plane that perpendicular to a direction of motion of the blades. For example, as best illustrated in
While the blades 502 are illustrated and described as extending through the center of the block 504, in some implementations shorter blades may be employed (e.g., each blade essentially cut in half), pairs of blades diametrically opposed to one another across a center point of the block 504. Such would use twice as many blades, and thus may not be preferred.
The stacking block 504 may include a plurality of channels 702a-702d (four shown, collectively 702). The plurality of channels 702 may be sized and dimensioned to receive portions of respective ones of the nested set of blades 502a-502d (
Block 504 may also include one or more registration features 704 that may be used to secure the nestable set of blades 502 in a desired position or orientation (e.g., pose) with respect to the block 504. The registration features 704 in block 504 may be complementary to the registration features 612a in the bottom blade 502a. The registration features 704 may comprise one or more holes or apertures in stacking block 504. These holes or apertures may be aligned with the registration features 612a in bottom blade 502a, which may comprise a hole or aperture. One or more fasteners 506 may be used to secure the nestable set of blades 502a-d to the block 504. As shown in
Each support plate 1302 may have a shape that is related to the shape into which the food item is to be cut. As shown in
The wipers 1304 may have the same profile as the profile of the support plates 1302, but with slightly larger dimensions. Thus, as shown in
As shown in
The optional bracket 1306 allows the cleaning assembly 116 to be attached to the frame 110 and secure each of the support plates 1302. The bracket 1306 may secure or fasten to each of the support plates 1302, thereby allowing the wipers 1304 to clean the entire length of the blades 502. In some implementations, the bracket 1306 may have a height that is greater than the height of the blades 502. Such an implementation may allow the upper assembly 104 to completely retract the blades 502 through the wipers 1304 such that the lower edge of the blades 502 are at a position above the wipers 1304. Such a configuration may allow for cleaning over the entirety of the faces 512 and 514 of each blade 502.
In implementations in which the blades 502 are curved or formed into other non-linear shapes or patterns, the support plate 1302 and corresponding wipers 1304 may have matching shapes.
In some implementations, the front wall 1608 may include a movable portion 1616 and a stationary portion 1618. The movable portion 1616 may be rotatably coupled to the stationary portion 1618 of the front wall 1608, and may rotate or pivot 1620 along an axis of rotation 1622 that runs transversely across the front wall 1608. In some implementations, a sensor 1617 may be located along or adjacent to a path that the movable portion 1616 travels when the movable portion 1616 rotates around the axis of rotation 1622. Such a sensor 1617 may, for example, be a proximity sensor, an RFID tag, a Hall Effect sensor, or any other type of sensor that may generate a signal when the movable portion 1616 of the front wall 1608 moves towards or engages the sensor 1617. The sensor 1617 may communicatively couple with the actuator 404, and may thereby transmit such a signal to engage the actuator 404. As such, the movable portion 1616 may activate or engage the sensor 1617 when the movable portion 1616 rotates downward, resulting in the sensor 1617 generating a signal that is transmitted to the actuator 404. When received by the actuator 404, such a signal may thereby trigger the actuator 404, which may act to move the cutting assembly 114 downward to cut the food item (e.g., the sauced, cheesed, topped flatten and partially cooked dough). In some implementations, such a sensor 1617 may be physically attached to the cover 1600. Such operation may provide a safety feature for the cutting system 100.
In some implementations, the movable portion 1616 of the front wall 1608 may include a handle 1626 that is physically secured to the movable portion 1616 of the front wall 1608. As such, the handle 1626 may be oriented and placed to facilitate the rotation 1620 of the movable portion 1616 of the front wall 1608. In some implementations, the handle 1626 may include a user-engageable switch 1628, or other similar component, that has an ON state and an OFF state. The user-engageable switch 1628 may communicatively couple with the actuator 404, and be operable to transmit a signal to the actuator 404, for example, when the user-engageable switch 1628 is in the ON state. In some implementations, the actuator 404 may need to receive such a signal from the user-engageable switch 1628 and a signal from the sensor 1617 before the actuator 404 can be engaged to thereby activate the transmission 112 to move the cutting assembly 114. Such a user-engageable switch 1628 may provide a further safety mechanism for the operation of the cutting system 100.
In some implementations, the cover 1600 may include an override switch 1630 that may have an ON position and an OFF position. When in the ON position, the override switch 1630 may prevent the cutting assembly 114 from being activated and moving out of the retracted position, even when the moveable portion is in or moved to a closed configuration or position from an opened configuration or position. For example, the override switch 1630 may interrupt the signal(s) from being communicated from the sensor 1617 and/or the user-engageable switch 1628 to the actuator 404. In some implementations, for example, the override switch 1630 may activate a solenoid 1632 that may be used to selectively couple or de-couple the sensor 1617 and the actuator 404.
In some implementations, the cover 1600 may be surrounded by a “light curtain,” comprised of one or more light generating components that generate electromagnetic waves and associated sensors oriented to receive the electromagnetic waves generated by the light generating components. As such, the cutting assembly 114 may operate automatically in a pass-through mode in which no operator interaction is needed for the cutting assembly 114 to process or cut food items. In such an implementation, the cutting assembly 114 may continue to operate in a pass-through mode unless one or more of the sensors stops receiving the corresponding electromagnetic wave from the light generating component, such as may occur, for example, when a human reaches through the “light curtain” and blocks one or more optical paths between a light generating component and associated sensor. When such a situation occurs, the cutting assembly 114 may automatically stop operating until, for example, the cutting assembly 114 is reset, such as may occur by activating by one or more user engagable input components 124.
The front wall 1608 may include a removable portion 1624 that may be selectively removed from the cover 1600. In some implementations, for example, the removable portion 1624 may provide access to the interior of the cover and be aligned with the cutting assembly 114 on the cutting system 100. As such, the removable portion 1624 may be used to access the cutting assembly 114 and thereby, for example, change and/or clean the blades 502.
The cover 1600 may surround a platform 1708 that may be positioned within the bottom region 1706 of the interior portion 1700 of the cover 1600. The platform 1708 may include, for example, one or more of the base 120 and/or the square base 350. The platform 1708 may be aligned with one or more apertures 1614a, 1614b. The apertures 1614a, 1614b may be used as an ingress and/or egress for food items into the interior portion 1700 of the cover 1600. The platform 1708 may include an upward-facing surface 1710 that may include one or more registration features 206, such as, for example, one or more depressions in the upward-facing surface 1710 of the platform 1708. Such registrations features 206 may be used to align a tray 118 onto the platform 1708. In some implementations, the platform 1708 may be selectively removed from the cover 1600. As such, another type of platform 1708, such as one that might be used to cut a different type or size of food item, may be optionally placed within the interior portion 1700 of the cover 1600.
The drawer 1802 may include a bottom 1822 that has an upward facing surface 1824. In some implementations, the bottom 1822 of the drawer 1802 may extend substantially across a width 1826 and a depth 1828 of the drawer 1802. The upward facing surface 1824 may be used to support the platform 1708. As discussed below, the upward facing surface 1824 may include one or more registration features that enable the platform 1708 to be selectively removed and replaced with another type of platform 1708, such as a platform 1708 that may be used for a different type of food. The drawer 1802 may include a front wall 1830 and an opposing back wall 1832, separated by the depth 1828 of the drawer 1802. In some implementations, the front wall 1830 may include a handle 1836 to facilitate the opening and the closing of the drawer 1802.
The drawer 1802 may be supported by one or more sets of extendable arms 1900 (
The drawer 1802 may have an open position, a closed position, and a cutting position. In such an implementation, the open position may correspond to a position in which at least a portion of the drawer 1802 is positioned in the exterior 1820 relative to the cover 1800. The closed position may correspond to a position in which the drawer 1802 has been moved towards and into the interior portion 1818 of the cover 1800 such that the front wall 1830 of the drawer 1802 is flush with the front wall 1810 of the cover 1800. The cutting position may correspond to a position in which the drawer 1802 has been pushed further into the interior portion 1818 of the cover 1800 past the closed position. As such, the front wall 1830 of the drawer 1802 may be recessed in relation to the front wall 1810 of the cover 1800 when the drawer 1802 is in the cutting position. In some implementations, the drawer 1802 may need to be moved or pushed further into the interior portion 1818 of the cover 1800 to reach the cutting position to trigger the actuator 404.
The drawer 1802 may trigger a sensor 1838 when the drawer 1802 has moved into the interior portion 1818 of the cover 1800, such as, for example, when the drawer 1802 is in the closed position and/or the cutting position. Such a sensor 1838 may be, for example, a proximity sensor, a switch, a Hall effect sensor, or any other similar type of sensor that may detect the presence of and/or be engaged by the drawer 1802 when the drawer 1802 has moved into the interior portion 1818 of the cover 1800. Such a sensor 1838 may be communicatively coupled to the actuator 404. In such an implementation, when the sensor 1838 is activated, the sensor 1838 may generate a signal and transmit such generated signal to the actuator 404, to thereby trigger the actuator 404. Once triggered, the actuator 404 may cause the cutting assembly 114 to move downward to cut the food item (e.g., the sauced, cheesed, topped flatten and partially cooked dough).
In some implementations, the cover 1800 may include a user-engageable switch 1842, or other similar component, that has an ON state and an OFF state. The user-engageable switch 1842 may communicatively couple with the actuator 404, and be operable to transmit a signal to the actuator 404 when the user-engageable switch 1842 is in the ON position. In some implementations, the actuator 404 may need to receive such a signal from the user-engageable switch 1842 and a signal from the sensor 1838 before the actuator 404 can be engaged to move the cutting assembly 114 to the cutting position. In some implementations, the user-engageable switch may be located on or proximate the handle 1836. Such a user-engageable switch 1842 may provide a further safety mechanism for the operation of the cutting system 100.
In some implementations, the cover 1800 may include an override switch 1844 that may have an ON position and an OFF position. When in the ON position, the override switch 1844 may prevent the cutting assembly 114 from being activated and moving out of the retracted position. For example, the override switch 1844 may interrupt the signal from being communicated from the sensor 11838 to the actuator 404. In some implementations, for example, the override switch 1844 may activate a solenoid 1846 that may be used to selectively couple or de-couple the sensor 1838 and the actuator 404, and/or to selectively couple or de-couple the user-engageable switch and the actuator 404.
The front wall 1810 may include a removable portion 1840 that may be selectively removed from the cover 1800. In some implementations, for example, the removable portion 1840 may provide access to the interior portion 1818 of the cover 1800 and be aligned with the cutting assembly 114 on the cutting system 100. As such, the removable portion 1840 may be used to access the cutting assembly 114 and thereby, for example, change and/or clean the blades 502.
In some implementations, the cover 1800 may include a display 1834 that may provide visual, audible, or other types of indications regarding information related to the cutting system 100. Such information may include, for example, the number of operations that the cutting assembly 114 has performed since the last maintenance or cleaning, the pressure and/or force provided by the transmission 112 to move the cutting assembly 114 to the cutting position, and/or the time that has elapsed since the cutting assembly 114 was last cleaned, and any other similar type of information.
The physical coupling components 2002 may be used to physically couple and secure the platform 1708 to the upward-facing surface 1824 of the drawer 1802. In some implementations, for example, the physical coupling components 2002 may include one or more threaded receptacles that may be configured to securely receive a screw or bolt that is placed through an aperture on the platform 1708. In some implementations, the physical coupling components 2002 may include one or more tabs or snaps that may be selectively engaged with corresponding apertures or snaps on the platform 1708. Such physical coupling components 2002 on the upward-facing surface 1824 of the drawer 1802 may be selectively and quickly de-coupled from the corresponding components on the platform 1708 to enable the platforms to be quickly and efficiently changed.
At 2102, the cutting system 100 receives a food item to be cut. The food item may be positioned on a tray 118, which in turn is positioned on the base 120 so that the food item is located in a desirable or appropriate location for cutting assembly 114. In some implementations, various registration features of the tray 118 and/or base 120 (e.g., the raised peripheral rim 204 of tray 118) may be used to position the food item. The cutting system may manually receive the item from a food preparation work or from an automated or mechanical system, for example a robot.
At 2104, the cutting system 100 receives a signal to engage an actuator 404. Such a signal may be received when a food preparation worker engages a start button or switch, such as, for example, user-engageable switches 1628, 1842. In some implementations, the actuator 404 may be responsive to a signal indicative of an appearance or presence of a food item properly placed on the tray 118 or base 120. This signal may be produced by one or more sensors (e.g., light emitter/receiver pair, pressure sensor, contact sensor) used to identify the presence and location of food items on the tray 118 and/or base 120. In some implementations, the signal may be produced by one or more sensors 1838 that identify the presence and/or location of the platform 1708 as being aligned with the cutting assembly 114. Alternatively, the signal may be produced manually, for instance by operation of a switch or key. In some implementations, the actuator 404 may need to receive one or more of such signals to be activated. In some implementations, an override switch, such as the override switches 1630, 1844, may interrupt the signal from being received by the actuator 144 at 2104, thereby preventing the actuator 404 from being activated.
At 2106, the cutting system 100 engages the actuator (e.g., piston, electric motor, solenoid) 404 to drive the rod or shaft 402 and the attached cutting assembly 114 in a downward direction. In yet other implementations, the cutting system 100 may be manually operated via a human operating a lever or other member to move the cutting assembly 114 between the extended and retracted positions.
At 2108, the blades 502 in cutting assembly 114 move downward to engage the corresponding channels 208 in the tray 118 or base 120. In some implementations, the transmission 112 may drive the plurality of blades 502 in cutting assembly 114 as a single assembly, e.g., such as when the blades are nested in the block 504, along the central axis 510. The cutting system 100 may continue to move the blades 502 downward until a condition is met. For example, the cutting system 100 may continue to extend the blades 502 downward until the actuator 404 has exceeded a defined threshold force. In some implementations, the actuator 404 may operate for a defined period of time to provide a downward force. That defined period of time may set to be sufficiently long to ensure that the blades 502 have fully engaged the corresponding channels 208 in the tray 118. In some implementations, the actuator 404 may continue to move the blades 502 until a signal is received that indicates that the blades 502 have made contact with the channels 208 in tray 118 or base 120, or that a portion of the cutting assembly 114 has traveled a defined distance.
At 2110, the actuator 404 may reverse the direction of travel of the blades 502, withdrawing the blades 502 in an upward direction towards the retracted or disengaged position. During this movement, the wipers 1304 may wipe, or “squeegee,” the faces 512 and 514 of blades 502 to remove food items stuck to the faces 512 and 514, thereby cleaning the blades 502.
At 2112, the cut food item is removed from the cutting system 100. In some implementations, a food preparation worker may remove the food item, for example along with the tray 118. In some implementations, the food item may be removed by an automated or mechanical system, for example a robot. A cover (not shown) may be placed on the tray 118 to form packaging that encloses the cut food item. The packaging along with the food item may, for example, be loaded into an oven for transport to a delivery destination. The food item may be cooked while being transported to the delivery destination, for example with one or more cooking parameters (e.g., temperature, time, humidity) controlled based on an estimated time to destination.
The cutting system 100 resets to receive and cut another food item.
