Abstract
A food dispensing machine and method of use that includes separately loaded, conveyed, and heated first and second food portions. A first food portion, such as a hot dog, is dispensed from a chain of portions in an sealing film via a first dispensing device, which slices the film and expels the food portion. The first food portion is loaded onto a projecting component, which transports the first food portion to a first heating device and rotates the food portion during heating. Second food portions, such as buns, within containers attached to a film so as to form a chain, are dispensed by a second dispensing device, which separates each container from the film for placement onto a tray. The tray conveys the second food portions to a second heating device, and the heated first and second food portions are combined and dispensed.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a food dispensing machine and method of use, and in particular to a machine for cooking, assembling, and dispensing uniformly shaped foods, such as hot dogs, sausages, or other meats in buns.




2. Background of the Technology




Machines for dispensing food items, such as for dispensing hot dogs, are known in the art. One such machine is disclosed in U.S. Pat. No. 5,873,299 to Leonid Leykin (“the '299 Patent”). In the machine of the '299 patent, a hot dog or sausage is removed from a standard package, placed on a fork holder, and then heated by an infrared oven. Individual buns are conveyed from boxes, and the heated sausage or hot dog is placed in the bun. The bun together with the sausage or hot dog is then warmed in a microwave oven, and the finished food item is dispensed.




However, there remain a number of problems with existing combined food dispensing device technology. For example, the use of infrared heating for the sausage/hot dog via the fork holding device of the '299 Patent, as well as use of a microwave oven for heating the combined sausage/hot dog and the bun, results in both a slow process and uneven heating of the food. The use of standard packages of hot dogs, from which sausages/hot dogs are individually withdrawn following opening, can result in staleness of sausages/hot dogs that are not immediately removed, as well as producing a potentially dangerous food situation (e.g., bacterial growth in sausages/hot dogs remaining in unsealed packages). Further, the pushing devices of the prior art used to individually remove sausages/hot dogs from containers introduce spillage and bacterial growth from, for example, leakage of juices from the containers, and the complexity of the pushing devices can produce jams or other problems in the devices.




There remains an unmet need to provide food cooking devices that overcome the problems with the prior art.




SUMMARY OF THE INVENTION




The present invention includes a food dispensing machine and method of use that includes separately loaded, conveyed, and heated first and second food portions, such as interior and exterior food portions (e.g., hot dog wieners and buns), which are combined after heating for dispensing to a customer.




In an embodiment of the present invention, a first food portion, such as a hot dog, sausage, hamburger, or other generally uniform food portion, is dispensed from a chain of portions formed using a sealing film. The portions are dispensed using a first dispensing device, which slices open the film and expels the first food portion. The first food portion is loaded onto a projecting component, which, via a first conveying device, transports the first food portion to a first heating device, such as a combined infrared and microwave oven. In an embodiment of the present invention, the projecting component rotates the first portion during heating.




In an embodiment of the present invention, second food portions, such as buns, are contained in containers forming a chain of portions via attachment to a second film. Each container containing a second food portion is dispensed by a second dispensing device, which separates the container and food portion from the film and places the container onto a specialized tray, such as a tray including one or more projections for engaging openings in each container. The tray is conveyed, via a second conveying mechanism, to a second heating device, such as a microwave oven, for heating of the second food portion. The heated first and second food portions are then combined and conveyed to a dispensing location.




Other features of embodiments of the present invention include the following: containers for containing the chains of first and second food portions, the containers being optionally located within refrigerated sections of the machine; various vending features, as are known in the art, such as product selection buttons, payment acceptance features, and change dispensing features; condiment and other feeding mechanisms within the machine and ports for dispensing such items from the machine; appropriate electrical and/or electronic control elements for controlling operation of the machine; a test operation panel for testing operation; and various features to facilitate access, cleaning, and maintenance.




Additional advantages and novel features of the invention are set forth in the attachments to this summary, and in part will become more apparent to those skilled in the art upon examination of the following or upon learning by practice of the invention.

, a pair of wheels


161


,


162


frictionally or otherwise engaged with one another are used in lieu of the first and second toothed wheels


112


,


113


shown in FIG.


15


. In an embodiment of the present invention, as shown in

FIG. 16

, a pulling component


160


, including, for example, a first wheel


161


, is frictionally or otherwise engaged with a second wheel


162


. In one embodiment, as shown in

FIG. 17

, the second wheel


162


is generally spool-shaped and, via rotational motion about, for example, axle


174

30


includes a non-rigid outer surface, such as a surface that comprises rubber or other soft material, for engaging the film


101


. In this embodiment, the first wheel has a much larger diameter than the second wheel, and the film


101


wraps around the first, larger diameter wheel as the film


101


is pulled. Because of the larger diameter of the wheel taking up the film


101


, as the film wraps around the larger diameter wheel, the effective diameter of the larger diameter wheel with the wrapped film


101


varies little relative to the larger diameter wheel without the wrapped film


101


. As a result, a large amount of film


101


can be wrapped around the larger diameter wheel before removal of the film


101


from the wheel is required.

31


is frictionally drawn past ramp


130


, resulting in cutter


140


cutting through film portion


180


of film


101


.




In one embodiment of the present invention, the cutter
