Definitions

  • the present invention relates to kitchen appliances, namely, an apparatus for slicing produce to precise dimensions.
  • the present invention falls into the category of countertop kitchen appliances. These devices exist under the premise that a chef in the house or a restaurant has many concurrent food preparatory tasks that need to be completed with just two hands and a limited time. In the rush to finish tasks and push food to the counter, even tasks that being attended to are performed in a scuttled, chaotic manner that produces visually unappealing results and wastes food.
  • Mechanized kitchen appliances have been around for a long time. Most simple appliances are designed to perform one or two functions exceptionally well. Tedious, repetitive and labor- intensive functions previously performed by humans have been largely delegated to simple appliances. Mechanized appliances derive power to do work from human action, usually through a rotating crank, a dipping paddle or triggered by a pedal. The next step beyond mechanization is automation of the mechanized process. The more simple or rudimentary the mechanical device, the easier it is to get it automated. Automation in this context means turning a mechanical device functioning under human prodding, usually by turning a crank handle or some other actuator, to having the mechanized drive function in a constant and ongoing manner under its own power, usually powered by electric motors.
  • Appliances performing cutting, crushing or dicing of raw food ingredients tend to be semi-automated or completely manual.
  • the delicate nature of the raw material proscribes the high oscillation frequency of the reciprocating automatic blades.
  • the one appliance is that has been successfully automated is the proverbial blender. Since in that context the raw material gets pulverized through one directional slicing, the use of blades produces the intended result.
  • the present invention introduces automation to the most delicate dicing operation, namely, the dicing of fruits and vegetables.
  • the challenge here is to produce a calculated, precise result, without requiring industrial grade equipment, or without pulverizing the raw material.
  • the solution embodied by the present invention produces calculated and consisted result, without requiring manual intervention.
  • the present invention is an automated dicing machine comprising of two upper grids that cut food stuffs introduced through an upper chute on an X and Y axis with respect to each other.
  • the third blade cuts on a Z axis, effectively completing the dicing process.
  • the movement of the blades is enabled using one or more electric motor having a rotating drive wheel(s).
  • the rotational force of the drive wheel is translated through the use of shafts and gear wheels to the cutting surfaces and converted into a reciprocating linear motion or into a rotating motion on various planes.
  • the device is comprised of three primary cutting surfaces.
  • the first cutter that is at the top of the device immediately above the second cutter.
  • the first cutter is comprised of a frame around plurality of parallel blades, oriented horizontally.

  • the second cutter is comprised of a frame around a plurality of parallel blades, oriented horizontally.
  • the parallel blades of the first cutter are positioned perpendicularly to the blades of the second cutter below.
  • the second cutter further contains a sidelong protrusion having an elongated slot.
  • the elongated slots of the first and second cutters are precisely stacked one above the other, with the elongated sections of each slot oriented perpendicularly to each other.
  • a rotating drive pin of a drive wheel is inserted into both of the elongated slots, causing the first and second cutters to move simultaneously.
  • the elongation of the slot on the first cutter forces the first cutter to be displaced back and forth, while the elongation of the slot on the second cutter, forces the second cutter to be displaced right and left, or in a perpendicular direction to that of the first cutter.
  • the first and second cutters working together cause a food item to be sliced along the length and width, into rod-like structures.
  • Either the first or the second cutter may be removed to produce a one-dimensional slicing cut.
  • the first and second cutter travel linearly within a caddie having protrusions to guide the linear movement of the first and second cutter.
  • the caddie is securely attached to the inner surface of the walls of the container.
  • a pair of parallel rails having internally facing upper and lower flanges running the length of the rail.
  • the flanges and rails run in parallel and face each other, creating a track within which the dip platform and the third knife slide back and forth during operation.
  • the distal ends of the parallel rails are attached to the inner surface of the container.
  • the right rail contains a notch to accommodate the passage of the pressure pin.
  • the pressure pin connects to a rod, which may also be referred to as the dipping rod.
  • the dipping rod slides up and down on a track that is mounted on the outside wall of the output chute.
  • the bottom end of the rod is supported by compression spring, which in turn is supported by the bottom wall of the container.
  • pivoting rod Connected laterally to the top of the rod is a pivoting rod.
  • the pivoting rod is pivotedly connected to the rod on its first end and pivotedly connected to a sliding rod on this second end. When the dipping rod is at rest, the pivoting rod is disposed on a downward diagonal between its two connection points.
  • the sliding rod glides back and forth between parallel guides that are mounted on an internal side wall that is attached underneath the bottom flange of the right-hand rail.
  • the first end of the sliding rod is a hinged connected to the pivoting rod.
  • the second end of the sliding rod is forced against a compression spring.
  • a free spinning wheel Immediately next to the second end is a free spinning wheel.
  • the free spinning wheel may be a spur gear, a helical gear or smooth wheel, having a substantial frictional coefficient.

  • Outer drive wheel being on the outer side of the sidewall, and the inner belt wheel being on the inner side of the sidewall.
  • the belt running on the inner belt wheels further comprises a sidelong meshing or drive pin that is pointed towards the third cutter. The pin moves in the same direction and at the same rate as the belt where it is mounted.
  • an upper drive wheel Directly above the outer drive wheel and mounted on the outside surface of the righthand rail is an upper drive wheel.

  • the distance between the upper drive wheel and the drive wheel below is slightly less than the diameter of the free spinning wheel.
  • the third cutter rides back and forth along the track created by the parallel rails.
  • the third cutter is made of two adjoining sections.
  • the area of each section equals the area of the opening of the input chute.
  • Each section is approximately three inches wide and three inches long. Both sections are surrounded by one continuous rectangular upright frame.
  • the front portion of the frame forms the forward section.
  • the rear portion of the frame forms the rear section.
  • the forward section the frame of the third cutter comprises a horizontal platform which is hingedly attached along the long sides of the frame, and which is not attached along its other edges.

  • the horizontal difference between the platform and the cutter is preferably half of an inch but may vary depending on sizes of the third cutter.
  • a drive block containing meshing teeth.
  • the meshing teeth are two protrusions on top and bottom of the drive block. Both protrusions are intended to catch the drive pin. Once the drive pin is engaged, the drive block will move in the direction of the travel of the drive pin and will pull the rest of the third cutter with it. Once the pin reaches the opposing inner belt wheel, the pin goes about the belt wheel and engages the other protrusion starting the motion of the cutter in the verse of the initial motion.

  • the food item is cut along the length and width into stick-like pieces, b.
  • the food item is pushed along the intake chute, eventually pressing against the
  • the platform begins to exert a downward pressure on the pressure pin, which in turn begins to push the dipping rod downward.
  • the downward riding rod forces the diagonally disposed pivoting rod into a straight orientation, inline with the plane of the reciprocating rod, which forces the reciprocating rod to slide toward the gap between the outer drive wheel and the upper drive wheel (both of which may be spur or helical gears).
  • the moving cutter cuts of a length of a food item corresponding to the horizontal gap between the third cutter and the horizontal platform.
  • the severed pieces of food item drop into an output chute through the linear gap between the horizontal platform and the leading edge of the third cutter,
  • the third blade continues to move laterally for the entire distance between the first and second belt wheels. Once the meshing pin reaches the first belt wheel, it encircles said wheel, catches the lower protrusion of the drive block, and begins to propel the third blade back toward the starting position. h. Once the third knife is back in its starting position, the forward gap is directly above the pressure pin, allowing the pressure pin to spring back up into the forward gap, thus pulling the reciprocal bar aware from the top and outer drive wheels, thus stopping the motion of the belt
  • a container should preferably be aligned beneath the output chute to catch the cubed food item.
  • All cutters may be removed for cleaning and all may work without any one or all of the other cutters being present, with the resultant piece being a slice along one, two or three planes, depending on which cutters are in place.
  • the automated dicing machine comprises two upper grids that cut food stuffs introduced through an upper chute on an X and Y axis with respect to each other.
  • the third blade cuts on a Z axis, effectively completing the dicing process.
  • the movement of the blades is enabled using one motor having a rotating drive wheel, which agitates one of the two upper grids.
  • the same rotating motor spins a connecting shaft which rotates a side shaft.
  • the top two grids 1 A and 2 A have interlocking elements. Therefore, agitation of one grid necessarily moves the other. In this case, the upper grid 1 A travels laterally back and forth, while the lower grid 2A travels laterally right and left.
  • the interlocking elements ensure that an agitation of one of the grids in one direction causes an equal or less agitation of the other grid in its respective direction.
  • Both upper and lower grids are traveling on internal ledges of a chamber and are easily removable for cleaning or to install grids of different size.
  • Below the upper blades is a chassis, with the middle section of the chassis corresponding to the overall opening of the two upper grids.
  • the chassis is formed by two parallel side walls that are connected by two parallel connecting rods. The distal end of each sidewall mounts a wheel.
  • each wheel is linked to a laterally parallel wheel with an axle, while the rims of linearly corresponding wheels are spanned by a drive belt, which creates two drive belts that are parallel to each other and which oscillate in unison.
  • the single blade is attached to the belts and spans the two parallel drive belts.
  • the blade is followed by a sweeper that is similarly mounted on the two parallel belts, with the distance between the blade and the sweeper corresponding to the opening of the two upper grids.
  • the axle of the wheel adjacent to the side shaft protrudes through the sidewall of the chassis to the other side, where it houses a simple spur gear.
  • the spurs of the simple spur gear correspond to the rack spurs on the rack gear that is housed on the side shaft.
  • there is no meshing between the spur gear and the rack gear since the rack gear is pushed downwardly by a helical compression spring that is mounted around the side shaft and above the rack gear.
  • the middle section of the chassis contains a frame which houses a pressure frame, with one of the edges of the pressure frame attached to one of the connecting rods of the chassis with the hinge, while the underside of the opposite edge being supported by at least one spring that is mounted on the frame, such that the pressure frame remains on a slanted grade when not under pressure from above.
  • Both the frame and the pressure frame form a substantially square flat frame that surrounds an empty middle area.
  • the purpose of the empty middle area is that is it permits the functionality of the third blade to be disabled, without removing the chassis.
  • Supported by the pressure frame is a pan.
  • the pan is flat and is sized to completely cover the empty middle area of the frame and the pressure frame.
  • the pan contains rims along each edge that lays parallel to the sidewalls of the chassis.
  • the rims are signed to prevent spillage of diced particles over the sidewalls of the chassis. There are no rims along the two edges of the pan that are parallel to the axles of the wheels. This is so that diced food particles can be swept over these edges by the sweeper.
  • the size of the cube is determined by the thickness of the pan. The thicker the pan, the shorter is the distance between the bottom of the pan and the third or horizontal blade. The shorter distance means smaller cubes, while a thinner pan, means a longer distance, and thus a larger cube.
  • the pan is freely removable to a) introduce a pan of desired thickness or to b) deactivate the functionality of the third blade.
  • a pressure pin Connecting to one of the unconnected side edges of the pressure frame is a pressure pin.
  • the pressure pin extends over the top edge of one of the sidewalls of the chassis to the other side thereof, where the pressure pin terminates just above the first end of a seesaw bar.
  • the second end of the seesaw bar is weighted so that the seesaw bar is biased to recline in the direction of the weighted end when not under pressure from the pressure pin.
  • the weighted end corresponds to the underside of a horizontal wheel of the side shaft and is connected to it through a hinge.
  • the pressure pin that is connected to the pressure frame is then displaced by the same degree and direction, begins to exert a downward pressure on the first end of the seesaw bar.
  • the pressure on the first end of the seesaw bar causes the weighted end to rise, come in contact with the underside of the rack gear and begin lifting the rack gear toward the spur gear.
  • the rack and spur gears are fully meshed and the ongoing rotation of the side shaft is now transmitted to the wheels of the chassis, which begin to rotate, setting in motion the lower blade and sweeper.
  • the lower blade slices the section of the produce occupying the space between the pressure pan and the lower blade, with the sweeper funneling the cut section off of the pressure pan into a side shoot.
  • the sweeper thus relieves the downward pressure on the pan and the pressure frame, allowing these to spring back up and thus terminating the motion of the lower blade and sweeper.
  • the upper and lower grids cut the produce in two vertical dimensions, while the lower blade cuts the third dimension horizontally.
  • the grids and the lower blade operate independently. Thus if only the upper grid is present, the result is a vertical slice. If both grids are present, the result is a two vertical intersecting cuts, resulting in a French fry type cut. If only the upper grid and the lower blade are present, the result is a slice of produce that is then cut into strips by the lower blade. If only the lower blade is present, the result is a horizontal cut.
  • the produce is introduced into the blade configuration through a shoot and driven down using a pressure block.
  • the drive end of the pressure block contains teeth that are of sufficient length to extend through the grids and terminate just above the lower blade.
  • the wheels of the chassis may be smaller, for smaller cubes or larger for larger cubes.
  • the space between each blade in the grids can be varied, with the teeth of the pressure block conforming to the size of each grid.
