Description
- The present invention is directed to food transport systems, and more particularly food transport systems including automated food heating and food cooling.
- Background Of The Invention Conveyor-based food movement systems are known in the art. Typically, food is placed onto the conveyor in a food preparation area and moved to a pick-up or dining room area. For example, such conveyor-based food movement systems have been used to transport food in sushi restaurants.
- Turning our attention to U.S. Pat. No. 6,554,106, the patent discloses a food transport system for use with sushi and the like. This invention includes the ability to identify the particular type of food product passing by on the conveyor and, if that product is old, redirect the food product to be disposed of. The reference however, does not include the concept of heating or cooling the food product as it comes by.
- U.S. Pat. No. 6,431,318 also discloses a sushi conveying system. This system includes a reader which is able to interpret the type of sushi passing by on the conveyor and then uses that information to instruct the kitchen to prepare types of food which are not currently on the conveyor system in the desired quantity. However, the system does not include the ability to heat or cool the food products on the conveyor.
- U.S. Pat. No. 5,419,410 also includes a food conveying system. This system monitors the type of food, although for purposes of directing it to the right location. In this patent, the customer orders the product and the product which is then delivered directly to them by means of a smart conveyor system. It does not include heating or cooling of the food once it is placed on the conveyor system.
- One disadvantage of these types of food conveyor systems is that they do not include automated heating of hot-served foods once they are placed onto the conveyor. Another disadvantage is that these types of food conveyor systems do not include automated cooling of cold-served foods once they are placed onto the conveyor
- In view of the above, there exists a need for a food conveyor systems that permits automated heating of hot-served foods and automated cooling of cold-served foods once they are placed onto the conveyor.
- The present invention provides a conveyor-based food transport system, wherein food is placed onto the conveyor in a food preparation area or kitchen and moved to a pick-up or dining room area. Advantageously, the system includes a food heater for heating food and drinks that require re-heating during circulation. The system further comprises a food cooler for cooling food and drinks that require re-cooling during circulation. According to one embodiment, the food heater is a steamer and the food cooler is a freezer.
- The conveyor-based food transport system further comprises a system for identifying the individual food and drinks being moved by the conveyor. The conveyor includes a plurality of mounting stations adapted to receive plates and disposed at predetermined intervals along the conveyor. Each mounting station includes a unique machine-readable identifier (e.g., a barcode or similar) specifying the type of food or drink to be mounted thereon. Additionally, each plate includes a unique machine-readable identifier specifying the type of food or drink to be served thereon. In some embodiments, mounting stations are not provided.
- One or more scanners preferably are disposed at predetermined locations along the conveyor. Scanner obtains information from the machine-readable identifiers concerning the type of food or drink disposed on each mounting station and plate. One or more temperature sensors (e.g., infrared sensors) are also disposed at predetermined locations along the conveyor. Temperature sensor determines the current temperature of each plate. Food or drinks that require heating are automatically directed toward food heater and food or drinks that require cooling are automatically directed toward food cooler. In some embodiments, a controller is provided for determining the circulation time of each plate of food and diverting foods to the food heater, food cooler or trash area based upon predetermined circulation time limits.
- One aspect of the present invention involves a food transport system comprising a conveyor including a controller that controls the movement of plates of food around the conveyor and determines the circulation time of each plate of food, a food heater and food cooler. The controller automatically diverts individual plates of food to the food heater if they require reheating and automatically diverts individual plates of food to the food cooler if they require cooling.
- A further aspect of the present invention involves a food transport system comprising a conveyor including a plurality of mounting stations for mounting individual plates of food. The conveyor comprises a controller that controls the movement of food around the conveyor, a food heater and a temperature sensor that senses the temperature of the individual plates of food.

FIG. 1 ,food transport system 10 is disposed within the interior of a restaurant, which includes adining area 110 andkitchen 120. A plurality of dining tables 130 are arranged within the dining area to accommodate the patrons of the restaurant. The dining area and kitchen may be separated by apartition 140, for example a glass wall. According to a some embodiments, theconveyor 20transports plates 30 of food directly to where patrons are seated. For example, the seating may be implemented in a typical bar style set-up, wherein the conveyor runs adjacent to the bar. Alternatively, the conveyor may be adapted to transport food in a zig-zag pattern through the tables in the dining area. - In operation, plates of food and drinks are prepared in
kitchen 120 and manually placed on the conveyor. Alternatively, the plates may be automatically loaded onto the conveyor, for example using one or more robotic arms.Conveyor 20 transports the food and drinks to the dining area in a direction indicated byarrows 150. Patrons of the restaurant may select individual plates of food and drinks passing through the dining area. Food and drinks that are not selected are transported along the conveyor back intokitchen 120. Such food and drinks may require heating or cooling to maintain a desired temperature range. More particularly, food and drinks that require heating are directed intofood heater 40 usingdiverter 170 and food and drinks that requires cooling are directed intofood cooler 100 usingdiverter 180. Additionally, food and drinks that have been in circulation on the conveyor for greater than a predetermined amount of time or revolutions are directed towardstrash area 190 usingdiverter 200. - In the illustrated embodiment, mounting
stations 25 are formed to have a circular shape such that the similarly-shapedplates 30 may be mounted thereon. As would be understood to those of skill in the art, mountingstations 25 andplates 30 may comprise many other shapes without departing from the scope of the present invention. Eachplate 30 preferably includes a unique machine-readable identifier 50 such thatscanner 60 may determine the type of food disposed thereon. With this information, the system may determine the appropriate price to charge a customer for the plate of food. Also, the system preferably monitors the number and type of foods and drinks that are directed towardtrash area 190 such that the kitchen workers know to reduce the preparation of unpopular foods and drinks. According to some embodiments, each mountingstation 25 comprises a mounting display for advertising food and drink products. The mounting display may feature a graphical display and sound system that is preprogrammed to promote that type of food or drink disposed on the mounting station. - Referring to
FIG. 2 ,food transport system 10 preferably includes acontroller 300 for controlling movement of food. Information may be entered intocontroller 300 from one ormore input devices 310 such as keyboards connected to an input side ofcontroller 300.Controller 300 includes asetting device 320, adetector 330 and atemperature monitor 340. Information obtained bycontroller 300 may be displayed by one ormore monitors 370 disposed in the kitchen area to assist the cooks in determining which food and drinks to prepare. -
Setting device 320 is used to set the type of food or drink that is to be served on a respective mountingstation 25. In addition, settingdevice 320 is also used to set the type of food or drink that is to be served on arespective plate 30. Detecting means 330 is used to calculate the circulation time of eachplate 30 circulating aroundconveyor 20 and locateplates 30 whose circulation time exceeds various predetermined time limits for the particular type of food or drink disposed on the plate. For example, when detecting means 330 detects aplate 30 whose circulation time exceeds a predetermined overall time limit, the controller automatically diverts the plate towardtrash area 190. More particularly,controller 300 shifts the plate ontotrash conveyor 345 usingdiverter 200. -
Temperature monitor 340 is used to check whether the current temperature of each plate falls within a predetermined temperature range for that particular type of food. Certain foods such as dry foods do not require heating or cooling at any time. However, other foods such as hot-served foods and cold-served foods may require heating or cooling, respectively. If the hot food is determined to be too cold, the plate is diverted ontofood heating conveyor 350, which passes throughfood heater 40. Contrariwise, if the cold food is determined to be too warm, the plate is diverted ontofood cooling conveyor 360, which passes throughfood cooler 100. Advantageously, the heating and cooling aspects of the food transport system of the present invention may be used to meet various health code requirements of different countries. - According to some embodiments, some
plates 30 include a predetermined heating circulation time or a predetermined cooling circulation time. If one of these circulation times are exceeded, the plate is automatically diverted to be heated or cooled. When detecting means 330 detects aplate 30 whose circulation time exceeds the predetermined heating time limit, the controller automatically diverts the plate ontofood heating conveyor 350. Likewise, when detecting means 330 detects aplate 30 whose circulation time exceeds the predetermined cooling time limit, the controller automatically diverts the plate ontofood cooling conveyor 360. According to other embodiments, the food transport system comprises more than one full-length conveyor line, for example including a hot line and a cold line, wherein one of the lines is disposed substantially concentrically inside of the other line.

As theplates 30 are conveyedpast scanner 60, the machine-readable identifiers on the plate and mounting station are read and the data concerning the start of circulation is automatically entered intocontroller 300. The information concerning the start of circulation is important for determining when the plate should be heated, cooled or sent to the trash area. Information concerning the start of circulation alternatively may be entered manually intocontroller 300 viainput device 310. - The plates are circulated along
conveyor 20 throughdining area 110 such that customers may select food and drinks of their choice to be eaten at dining tables 130. Empty mountingbases 25 are conveyed back into the kitchen area wherescanner 60 determines that the mounting base is vacant because it does not sense the presence of a machine-readable identifier 50. The scanner then notifies the controller that the appropriate food or drink should be added to the empty mounting base.Controller 300 outputs this information to monitor 370 for display within the kitchen area, thereby notifying the cooks of the types of food and drinks that require replenishing. -
Plates 30 that have not been selected are recirculated around the conveyor until they are selected or diverted to be heated, cooled or disposed of. More particularly, whenscanner 60 identifies aplate 30 returning tokitchen 120, detecting means 330 automatically calculates the total circulation time of the plate.Controller 300 automatically divertsplates 30 that exceed a predetermined circulation time ontotrash conveyor 345. The food and drinks on these plates are discarded intrash area 190 and the plates are removed for washing. In addition, the data concerning circulation time is cleared fromcontroller 300. - After being washed, the plates may be recirculated with fresh food and drinks. The empty mounting
station 25 onconveyor 20 eventually reachesscanner 60, which determines that the mounting base is vacant since it does not sense the presence of a machine-readable identifier 50. The scanner then notifies the controller that the appropriate food or drink should be added to the empty mounting base.Controller 300 outputs this information to monitor 370 for display within the kitchen area, thereby notifying the cooks of the types of food and drinks that require replenishing. -
Plates 30 returning tokitchen 120 also pass bytemperature sensor 70, which determines the current temperature of eachplate 30. This data is inputted into the controller such that temperature monitoring means can determine whether the plate requires heating or cooling.Controller 300 automatically diverts food and drinks that require heating intofood heater 40 usingdiverter 170. In addition,controller 300 automatically diverts food and drinks that requires cooling intofood cooler 100 usingdiverter 180. - Referring again to
