In the present embodiment, the springs 452 can be inserted in their respective housings 460 by pivoting the upper portion 430 relative to the lower portion 432 using the hinges 434, thereby revealing the upper open ends of the housings 460. It is contemplated that in some embodiments, the springs 452 could be other resiliently deformable members. In other embodiments, the springs 452 could be omitted.
[0143] Each one of the fingers 450 also includes a fingertip 454 that is connected to a lower end of the spring 452 and that is opposite to the base 420 (i.e., fingertip 454 is below the corresponding base 420). Each one of the fingertips 454 is moveable in a vertical direction with respect to the base 420, and is biased away from the base 420 by the spring 452. In the present embodiment, each one of the fingertips 454 is also slidable in the corresponding housing 460. As will be described in greater detail below, the fingers 450 are adapted to pick up utensils of various shapes.
[0144] Each one of the fingers 450 also includes a permanent magnet 456 provided at a lower end of the fingertip 454. It is contemplated that in some embodiments, the permanent magnet 456 could be another type of attachment such as, for instance, an electro-magnet, a suction cup and/or a nozzle that suctions air. As will be described in greater detail below, the permanent magnet 456 is adapted for attaching a utensil to the fingers 450.
[0145] In some embodiments, as mentioned above, the springs 452 could be omitted. In such embodiments, a weight of the fingertips 454 and a weight of the corresponding permanent magnets 456 can result in the fingertips 454 being pulled down away from the base 420.
[0146] Referring to
[0147] Focussing now on the base 420 and the features connected thereto, as mentioned above, the fingers 450 can pick up utensils of various shapes. When the utensil being picked up is not flat, the fingertips 454 can move in their housings 460 to partially conform to the shape of the utensil. As such, when the utensil has a portion extending toward the fingers 450, the fingertips 454 can slide inwards.
[0148] For instance, referring to
[0149] Referring to
[0150] The comb 500, which in the present embodiment is connected to the frame 110, has six upwardly extending teeth 502 that define five spaces 504 (best seen in
[0151] The chute 550, which in the present embodiment is also connected to the frame, is curved. It is contemplated that in other embodiments, the chute 550 could be a flat surface. The chute 550 is oriented such that the utensils falling thereon are guided to fall on the wrapping assembly 100.
[0152] As will be described in greater detail below, in the present embodiment, when the utensil picker 400 has picked up utensils, and the movable arms 410 move the fingers 450 through the spaces 504 in the comb 500, the teeth 502 of the comb 500 separate the utensils from the ends of the fingers 450 as the fingers 450 pass through the comb 500 and the utensils fall toward the chute 550. The chute 550 then slows the fall of the utensils and directs them onto the wrapping assembly 100. It is contemplated that in embodiments where the comb 500 is omitted, the movable arms 410 would move the utensil picker 400 until it is aligned with the chute 550, and drop the utensils thereon via some other mechanism.

[0156] The fork 80, spoon 82 and knife 84 are then dropped on the chute 550 that is disposed above the wrapping assembly 100. The fork 80, the spoon 82 and the knife 84 are dropped from the utensil picker 400 onto the chute 550, as the fingers 450 pass through the spaces 504, and the fork 80, the spoon 82 and the knife 84 encounter the comb 500 which separates them from the fingers 450. It is contemplated that there could be more or less than three utensils being placed on the napkin 60.
[0157] Once the utensils 80, 82, 84 are on the napkin 60, the wrapping assembly 100 is configured in the folding configuration, as shown in
[0158] The wrapping assembly 100 is then configured in the wrapping configuration, as shown in
[0159] The endless belt 150 is then turned around the driven roller 120, the upper idler roller 130 and the lower idler roller 140 by the motor 122 rotating the driver roller 120, thereby wrapping the napkin 60 around the fork 80, the spoon 82 and the knife 84. Once the endless belt 150 has moved sufficiently to properly wrap the napkin 60 around the fork the spoon 82 and the knife 84, the motor 122 is stopped, thereby stopping to turn the endless belt 150. This could be determined by a predetermined amount of time by which the motor 122 is to be operated or by a predetermined number of rotation of the driven roller or by some other factor.
[0160] The wrapping assembly 100 is then returned to the initial configuration by moving the upper idler roller 130 away from the driven roller 120 in an arcuate path, and by lowering the lower idler roller 140. This causes the fork 80, the spoon 82 and the knife 84 that are wrapped in the napkin 60 to be disposed on the flat horizontal portion 152 of the endless belt 150. It is contemplated that a taping apparatus could be added to apply tape, or a band of paper with adhesive, around the napkin 60 to secure the napkin 60 around the utensils 80, 82, 84. The wrapped utensils are then removed manually from the wrapping assembly 100. It is contemplated that an automated mechanism could be used to pick up the wrapped utensils from the wrapping assembly 100. It is also contemplated that the motor 122 of the wrapping assembly 100 could be turned on to move the wrapped utensils off the endless belt 150 into a basket or some other receptacle.
[0161] It is contemplated that in some embodiments, some of the steps of the methods could be done simultaneously, so long as the napkins are delivered to the endless belt 150 before the utensils
[0162] In the present embodiment, the method described above is automated by the controller 70.
[0163] It is contemplated that the wrapping assembly 100 could be used without the napkin delivery assembly 200 or without the utensil delivery assembly 300 or without both. It is also contemplated that in some embodiments, the apparatus 50 could have one or two of the wrapping assembly 100, the napkin delivery assembly 200 and the utensil delivery assembly 300, but with one or two of a wrapping assembly, a napkin delivery assembly and a utensil delivery assembly that is/are different from the ones described above. Similarly, it is contemplated that in some embodiments the magazines 302, 304, 306 could be used with a different type of utensil picker and that the utensil picker 400 could be used with a different type of magazines.
[0164] Referring now to
[0165] Features of the apparatus 1050, the wrapping assembly 1100, the napkin delivery assembly 1200 and the utensil delivery assembly 1300 that are, respectively, generally similar to those of the apparatus 50, the wrapping assembly 100, the napkin delivery assembly 200 and the utensil delivery assembly 300 described above have been labeled with the same reference numerals and will not be described again in detail. That being said, the configuration of the apparatus 1050 differs slightly from the configuration of the apparatus 50. For instance, the configuration of the arms 220, 230 of the napkin delivery assembly 1200 are different from the configuration of the arms 220, 230 of the napkin delivery assembly 200 and the configuration of the arms 410, 415 of the utensil delivery assembly 1300 are different from the configuration of the arms 410, 415 of the utensil delivery assembly 1300. Additionally, the motors 229, 239 of the napkin delivery assembly 1200, and the motors 418, 419 of the utensil delivery assembly 1300 have been replaced by motorized lead screw actuators. Actuation of the motorized lead screw actuators 229, 239, 418, 419 result in the movement of the napkin delivery assembly 1200 and the utensil delivery assembly 1300. Limit switches (not shown) control the motorized lead screw actuators 229, 239, 418, 419 to limit movement of the napkin delivery assembly 1200 and the utensil delivery assembly 1300.
[0166] Turning to
[0167] In the present embodiment, the driven roller 1120, which is operatively connected to the motor 122, is vertically below the idler rollers 1130, 1140, whereas the idler rollers 1130, 1140 are generally vertically aligned with one another. It is contemplated that in some embodiments, the motor 122 could be connected to another one of the rollers. For instance, in other embodiments, the idler roller 1130 could be configured to be the driven roller.
[0168] The idler roller 1130 is disposed inside the frame 110, and is rotationally connected thereto about a rotation axis 1131, which is fixed relative to the frame 110.
[0169] The idler roller 1140 is disposed inside the frame 110, and is connected to the frame 110 via a movable member 1142 (best seen in
[0170] The idler roller 1140 is movable between an initial position a wrapping position. It is contemplated that in some embodiments, the idler roller 1140 could be moved to positions intermediate these two positions. In the initial position (shown in

[0174] The apparatus 1050 is configured to, by using the napkin delivery assembly 1200 and the utensil delivery assembly 1300, place a napkin and utensils on the wrapping assembly 1100. As the method for accomplishing this is similar to the method for apparatus it will not be re-described in detail herewith.
[0175] Once utensils 80, 82, 84 are placed on the napkin 60, as shown in
[0176] Eventually, when the idler roller 1140 reaches the wrapping position, the wrapping assembly 1100 is in the wrapping configuration, as shown in
[0177] The endless belt 150 is then turned around the driven roller 1120 and the idler rollers 1130, 1140 by the motor 122 rotating the driver roller 1120, thereby wrapping the napkin 60 around the utensils 80, 82, 84. Once the endless belt 150 has moved sufficiently to properly wrap the napkin 60 around the utensils 80, 82, 84, the motor 122 is stopped, thereby stopping to turn the endless belt 150.
[0178] The wrapping assembly 100 is then returned to the initial configuration by moving the idler roller 1140 away from the driven roller 1120 and the idler roller 1130, toward the initial position. This causes the utensils 80, 82, 84 that are wrapped in the napkin to be disposed on the generally flat horizontal portion 152 of the endless belt 150 as shown in
[0179] Similarly to the apparatus 50, the method described hereabove with reference to the apparatus 1050 is automated by the controller 70.
[0180] Modifications and improvements to the above-described embodiments of the present technology may become apparent to those skilled in the art. The foregoing description is intended to be exemplary rather than limiting. The scope of the present technology is therefore intended to be limited solely by the appended claims.
