The present disclosure relates generally to a cutlery utensil dispenser, and particularly to a multi-stack cutlery utensil dispenser.
Eating facilities often provide cutlery utensils in dispensing bins, where all customers place their hands into the bins in order to retrieve a knife, fork, spoon or spork. While such arrangements provide for economical dispensing of cutlery utensils, as opposed to sets of utensils being separately wrapped in plastic sleeves, the open air bins are not very hygienic, and can spread hand-carried bacteria and the like to other utensils in the bin or potentially to another customer.
In an attempt to address concerns relating to the dispensing of hygienic cutlery utensils, enclosed dispensers have been employed where a stack of cutlery utensils are placed in a utensil compartment and dispensed one at a time on command by operation of a dispensing lever. Such arrangements may be suitable for their intended purpose, but are also limited by the capacity of utensils they are capable of holding. One remedy to such a deficiency may be to simply make the utensil compartment taller, thereby enabling multiple stacks of pre-measured and pre-assembled cutlery utensils to be placed one on top of the other. However, such a dispenser would be quite tall, would require refilling from a relatively high level, and would require each of the separate stacks to be properly aligned one on top of the other during refilling so that the cutlery utensils are properly aligned for dispensing. In view of these and other deficiencies, there is a need in the art for an improved cutlery utensil dispenser.
An embodiment of the invention includes a cutlery utensil dispenser having a plurality of N utensil compartments and a dispensing mechanism. Each of the utensil compartments are so dimensioned and configured to house a stack of utensils, each compartment having a dispensing opening through which a dispensed utensil passes. The dispensing mechanism includes a drive member in operable communication with a plurality of N driven members, each driven member being associated with a respective one of the compartments, each driven member having a dispensing arm that facilitates the dispensing of a utensil from the associated compartment. Actuation of the drive member causes simultaneous actuation of each driven member that causes a utensil to be dispensed from each of the plurality of compartments in repeatable succession one at a time.
Another embodiment of the invention includes a cutlery utensil dispenser for dispensing cutlery utensils. The dispenser includes a utensil compartment so dimensioned and configured to house a stack of cutlery utensils, a dispensing mechanism disposed and configured to facilitate dispensing of a utensil from the utensil compartment on command, means for providing electrical power, an electric motor in operable communication with the power means and the dispensing mechanism, and a controller in operable communication with the motor. The controller includes a processing circuit responsive to computer executable instructions which when executed by the processing circuit facilitates dispensing of a utensil from the utensil compartment by operation of the motor on command.
Another embodiment of the invention includes a cutlery utensil dispenser for dispensing cutlery utensils. The dispenser includes a utensil compartment, a dispensing mechanism in operable communication with the utensil compartment, an electric motor in operable communication with the dispensing mechanism, and a controller in operable communication with the motor. The controller includes a processing circuit responsive to computer executable instructions which when executed on the processing circuit facilitates dispensing of a utensil from the utensil compartment by operation of the motor and the dispensing mechanism on command.
Another embodiment of the invention includes a method of automatically dispensing a single piece of cutlery utensil from an electronically controlled and motor driven cutlery utensil dispenser. A sensor is used to sense a presence of a piece of cutlery at a dispensing tray of the dispenser and a single piece of cutlery is automatically dispensed to the dispensing tray for subsequent removal by a user in response to a piece of cutlery not being present at the dispensing tray. The sensor is used to sense a presence of the dispensed cutlery at the dispensing tray prior to removal by a user, and in response to the sensor sensing removal of the dispensed cutlery from the dispensing tray, a next-to-be-dispensed single piece of cutlery is dispensed to the dispensing tray for subsequent removal by a user.
Referring to the exemplary drawings wherein like elements are numbered alike in the accompanying Figures:
An embodiment of the invention, as shown and described by the various figures and accompanying text, provides a cutlery utensil dispenser configured for dispensing utensils one at a time in succession from a plurality of utensil compartments each housing a stack of utensils, and a dispensing method applicable thereto. While the embodiments described herein depict a fork as an example utensil, it will be appreciated that the disclosed invention is also applicable to other cutlery utensils, such as knives, spoons and sporks, for example. The stack of utensils may be made from any type of material, such as plastic, metal, wood, or plastic-coated compressed paper, for example.
In an embodiment, each compartment 120, 122 has a top frame 130, a bottom frame 135, and side supports 140 for retaining the stack of utensils 125. The bottom frame 135 has a dispensing opening 145 (best seen by referring to

With reference to
As an aside, a dispenser 100 employing a manually actuatable lever 255 may have the gear structure of the drive member, driven members and idler configured such that one revolution of the lever 255 causes one increment of revolution (1/N revolution) of the driven members, which is a convenient and natural mode of manual operation for an end user. On the other hand, a dispenser 100 employing a motor 260 may have the gear structure of the drive member, driven members and idler configured such that any defined degree of rotation of the motor causes one increment of revolution (1/N revolution) of the driven members, where the defined degree of rotation of the motor 260 is a matter of design choice.
With reference still to
While certain combinations and quantities of drive member, driven members and idlers have been described herein, it will be appreciated that these certain combinations are for illustration purposes only and that any combination of any of the foregoing drive member, driven members and idlers may be employed in accordance with an embodiment of the invention as disclosed herein. Any and all such combinations are contemplated herein and are considered within the scope of the invention disclosed.
While an embodiment of the invention has been described employing a gear-driven dispenser, it will be appreciated that the scope of the invention is not so limited, and that the invention also applies to a dispenser having any other type of drive system suitable for the purposes disclosed herein, such as a belt-drive system or a chain-drive system for example.
As discussed above, an embodiment of the dispenser 100 employs a plurality of dispensing trays 200, 202 (
In an embodiment, and to assist in a uniform sliding motion of each dispensed utensil 125, a vibratory action may be imparted to any of the aforementioned trays, 200, 202 and 285, by way of any suitable vibratory device 290, such as an electromagnetic or piezoelectric vibrator/buzzer/shaker for example. In an embodiment, the vibratory device 290 is controlled by controller 275 so that the respective tray vibrates in a timed manner in response to a dispense command.
In an embodiment, and with reference to
In an embodiment, and with reference to
Alternative to the plurality of N dispensing trays 200, 202 (
In an embodiment, the first dispensing surface 325 comprises a slope that promotes sliding of the holding portion 235 of the dispensed utensil 125 from the receiving end 305 toward the dispensing end 310, and the second dispensing surface 330 comprises a slope that retards such sliding of the utility portion 240 of the dispensed utensil 125 from the receiving end 305 toward the dispensing end 310. As illustrated in
From the foregoing, it will be appreciated that the first and second regions 315, 320 are configured with sliding surfaces that promote differing degrees of slippage, as long as the differing degrees of slippage cause the dispensed utensil 125 to rotate during dispensing to present the holding portion 235 of the dispensed utensil to the end user.
In an embodiment, the second region 320 also includes a partial wall 335 disposed at the dispensing end 310 of the second region 320 to capture the utility portion 240 of the dispensed utensil 125 as the holding portion 235 of the dispensed utensil 125 slides under the influence of gravity toward the dispensing end 310. An opening 340 at the second region 320 is disposed between the partial wall 335 and the first region 315, which is so dimensioned as to permit the user to withdraw the dispensed utensil 125 from the dispenser 100 through the opening 340 by interfacing with the holding portion 235 of the dispensed utensil 125.
By employing the single tray 300 as described above, the combination of sloped ramps 325, 330 will reliably turn a dispensed cutlery utensil 125 independent of variations in frictional forces at the sliding surfaces.
To further assist in reliably turning a dispensed cutlery utensil 125, the center of gravity 345 of a given utensil 125 relative to the left edge 350 of the first dispensing surface 325 is such that the center of gravity 345 is disposed over the second dispensing surface 330 and not over the first dispensing surface 325. That is, as a dispensed utensil 125 drops under the influence of gravity toward the single dispensing tray 300, the center of gravity 345 of the dispensed utensil is positioned over and falls in line with and towards the second dispensing surface 330. Since knives, forks, spoons and sporks naturally may have centers of gravity at different locations along their respective lengths, a dispenser 100 employed for dispensing one type of utensil may have first and second dispensing surfaces 325, 330 with different widths than another dispenser 100 employed for dispensing a different type of utensil. All such dispensers employing first and second dispensing surfaces 325, 330 of different widths are considered within the scope of the invention disclosed herein.
To further assist in accurately positioning the holding portion 235 of a dispensed utensil 125 at the dispensing end 310 of tray 300, and with reference now to
While an embodiment of the invention has been described employing a manually actuatable lever that rotates about an axis in one revolution increments to operate a gear-driven system of the dispenser, it will be appreciated that the scope of the invention is not so limited, and that the invention also applies to a dispenser having any other operable lever arrangement suitable for the purposes disclosed herein, such as a cantilevered lever that is depressed through a defined amount of displacement, operates a drive system through a pawl-and-ratchet interface, and is spring loaded to return to a detent position ready for another dispensing action.
In addition to the forgoing, an alternative embodiment of the invention includes a controller 275 having a processing circuit (generally depicted by reference numeral 275) responsive to computer executable instructions which when executed on the processing circuit facilitate dispensing of a utensil 125 from a respective one of the utensil compartments 120, 122 by operation of the motor 260 on command.
With reference now to
In an embodiment, the sensor 370 is disposed to sense a utensil 125 at the opening 330 disposed between the partial wall 335 and the first region 315, and in a further embodiment is disposed to sense a utensil resting at a bottom of the V-type notch formed by sloped surface 355 or 360. However, it is envisioned that the sensor 370 may be placed at any practical location to sense the presence or absence of a utensil 125.
In an embodiment, the sensor 370 is an optical sensor disposed to direct a sensor signal 380 in a direction substantially more toward a utensil 125 at the dispensing tray 300 (directed upwards for example) than toward a user requesting a utensil from the dispenser (directed forwards for example), as illustrated in
