Description
Technical Field
The utility model relates to a transmission system especially relates to a dining room space track power transmission system.
Background
With the rapid development of the catering industry, the industry has put higher demands on the rapid and accurate delivery of food and/or beverage. Currently, the existing transportation systems in restaurants include a revolving sushi transportation system, a gravity transportation system, and a cart transportation system.
The rotary sushi transport system is based on a powered transport mechanism (e.g., a conveyor belt) that transports items such as food and/or beverages. The transport mechanism forms a closed loop between the back-end work area of the restaurant and the dining area of the customer, the container holding the articles is placed on the transport mechanism and moved to the front of the customer, and the customer takes the articles off the transport mechanism. However, since the container is placed on the conveying mechanism and is liable to slide on a large slope, it cannot be adapted to cross-convey food in a multi-story space of a restaurant, resulting in poor space utilization of the restaurant. Moreover, the conveying mechanism divides the single-layer space of the restaurant into a plurality of areas, and communication and walking of personnel are influenced. In addition, the transport system cannot accurately transport the articles to the customer, the customer still needs to take and place the articles by himself, and once the articles are missed, the customer needs to wait for the next article/article to be transported to the customer position.
The gravity transfer system places the items in a conveyor that slides down a track under the force of gravity onto a table attached to the end of the track. Due to the adoption of gravity transmission, the starting point of the track needs to be arranged in a region higher than the terminal point of the track, or the goods are lifted to a position higher than the terminal point of the track by virtue of the lifting device, so that the space utilization rate is reduced, and the complexity of a transmission system is increased. To ensure that the conveyor can slide down the track by gravity, higher demands are placed on the design of the track and the conveyor. In addition, the transmission device generates large noise when sliding under gravity.
The trolley conveying system is used for placing objects in a conveying device similar to a trolley, and the conveying device moves along a track or a pre-planned route by means of self power to convey the objects to a customer. Since the power of the transmission device depends on electric power driving, if battery driving is adopted, a manager has to replace the battery regularly, and the transmission device is generally small in size and cannot be provided with a large-capacity battery, so that the replacement frequency is very high. If the external power supply is adopted for driving, the transmission device needs to be connected with an electric wire or a complex power supply circuit is arranged in the track, so that the attractiveness of the restaurant is influenced, the operation cost of the restaurant is increased, and even waiters or customers are stumbled, unnecessary dangers are brought.

To further explain the technical means and effects adopted by the present application to achieve the intended purpose, the following detailed description is given to the specific structure and effects of the present application in conjunction with the accompanying drawings and embodiments. Hereinafter, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated, and are not to be construed as limiting the order of the technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of the present application, "a plurality" means two or more unless otherwise specified.
The embodiment of the application provides a restaurant space track power transmission system, which can be applied to restaurants with one or more layers of three-dimensional spaces to transmit food and/or beverage and other articles, and the articles can also be called dishes. Fig. 1 shows a schematic configuration of a restaurant space track transportation system, and as shown in fig. 1, the transportation system includes a work area 1, a customer area 2, a track system 4, and a conveyor 5. Wherein the work area 1 is used for the preparation, distribution, preparation and/or presentation of goods, the work area 1 may be a counter area of a restaurant, the counter area being used for completing the cooking and/or preparation of food and/or beverages. The work area 1 can also be a distribution area connected to a kitchen area, which is used for distributing or placing items. Customer area 2 is for customers to receive items, customer area 2 may be an area where customers eat, which may house one or more tables 21 and seats 22; customer area 2 may also be an area where customers take meals, where they take food and/or beverages. Optionally, the transport system may also comprise a recovery section 3, the recovery section 3 being adapted to recover items such as the conveyor 5, food waste and remaining beverage and to perform the necessary cleaning of the conveyor 5 and the containers containing food and/or beverage. The container may be a bowl, dish, plate, cup, etc., and the application is not limited thereto. The number of the working area 1, the customer area 2 and the recycling area 3 may be one or more, and may be set according to actual needs, which is not limited in this application. It will be appreciated that the work area 1 and the recovery area 3 may also be combined into one area in the case of a limited restaurant space. Optionally, the transportation system of the present application may further include a main control device of the restaurant, the main control device being configured to control operations and operations of the various parts of the transportation system, and to obtain and store relevant information of the various parts, such as status information of the transportation device, where the status information includes information of a position of the transportation device on the track system, an operation speed, a battery level, contents of the transported object, a destination position of the transportation, and the like. The master control device may be any known type of server or smart terminal, such as a mobile phone or a tablet computer, and the present application does not limit this.
The work area 1, the customer area 2 and the recovery area 3 are interconnected via a rail system 4. In one example, the track system 4 forms a closed loop R1 between the work zone 1, the customer zone 2, and the recovery zone 3. The conveyor 5 is used for loading and transporting the articles along the track system. The conveyor 5 can be moved from any of the above-mentioned areas back to the area via the rail system 4, so that a circulating operation is achieved, whereby the conveyor 5 does not require the intervention of staff or additional automation equipment. I.e. continuously to a specific position on the rail system 4. Alternatively, the track system 4 may form a closed loop between any two of the work zone 1, the customer zone 2, and the recovery zone 3. Alternatively, a plurality of closed loop track systems may be provided in the restaurant space, each of which may operate one or more conveyors 5, thereby further reducing the intervention of personnel or automated equipment.
In another example, track system 4 sequentially connects work zone 1, customer zone 2, and recovery zone 3 to form open loop R2. The transport device 5 can be moved from a starting position (working area 1) of the rail system 4 to an end position (recovery area 3) of the rail system 4 via a rail. After the conveyor 5 has moved to the end position, it can be returned to the starting position along the rail system, or it can be moved back to the starting position by a worker or an automation device. Alternatively, the track system 4 connects the work area 1 and the customer area 2 in series to form an open loop R3-R5, and the conveyor 5 may carry food and/or beverages from the work area 1 to the customer area 2 for delivery to the customer.
In another example, the track system 4 may include a bifurcation device disposed at a bifurcation point of the track system for altering a line of the track system 4 to adjust a travel path of the conveyor 5. Alternatively, the track system may be one track in the working area and extend the one track to two or more tracks by means of one or more branching means. After loading the work area 1 with the items, the conveyor 5 runs via the fork device onto the target line, thereby transporting the items to the respective customer area 2. Alternatively, the track system may be one line in the recovery zone, into which two or more lines connecting two or more customer zones 2 are connected by one or more branching means. The transport means 5 runs from the customer zone 2 back to the recovery zone 3 via the branching means onto the one line. It will be appreciated that the branching means may be provided as required by the track system 4, may extend from one track to two or more tracks, or may converge from two or more tracks to one track. Thus, fewer lines, such as one or two lines, may be provided at smaller spatial locations, while more lines may be provided at larger spatial locations. Since the working area of a restaurant (e.g., a kitchen area for food and/or beverage dispensing) is typically small, the conveyor may be transported to more lines by the cooperation of one or two lines provided at the working area and the branching device.
The transfer process of the closed-loop track system and the open-loop track system is described in more detail below. In one example, taking the example of a closed loop path R1, the track system 4 is connected in series between the work area 1, the customer area 2 and the recycling area 3, the head and tail portions of the track system 4 being connected to each other, and the conveyor 5 is continuously movable on the track to transport food and/or beverages from the work area 1 to the customer area 2 and food waste and remaining beverages from the work area to the recycling area 3 where they are removed, the conveyor 5 being able to be groomed or cleaned. The conveyor 5 then returns to the working area 1 and continues the next cycle of transport.
In another example, taking open loop path R3 as an example, track system 4 connects work area 1 and customer area 2, track system 4 is located at one end of work area 1 as the track starting point and located at the other end of customer area 2 as the track ending point, conveyor 5 transports cooked or prepared food and/or beverages from work area to customer area, i.e., from the track starting point to the track ending point, and conveyor 5 is collected by a worker or automated equipment (e.g., an automated cart) at the track ending point and transported back to the track starting point at the work area for the next transport, and optionally conveyor 5 may return itself from customer area 2 to work area 1 along track system 4.
Fig. 2 shows a schematic view of a conveyor running on a track system according to an embodiment of the present application. As shown in fig. 2, the track system 4 comprises a substantially horizontal track unit 41, an ascending or descending spiral track unit 42 in the form of a continuous spiral. Alternatively, the track system 4 may further include track units such as an ascending track unit 43 inclined upward and a descending track unit 44 inclined downward. It is understood that other shapes of track units may be provided according to the situation and actual needs of the restaurant space, so that those skilled in the art can construct tracks of various lines and shapes, and the present application is not limited thereto. By means of the above-mentioned rail system 4, the conveyor 5 can be run to different positions of the rail system 4, so that the purpose of the conveyor 5 to convey an object to a specific position of the rail system 4 is achieved.
In one embodiment, the conveyor 5 enters the spiral track unit 42 along the horizontal track unit 41, enters the ascending track unit 43 after leaving the spiral track unit 42, enters the descending track unit 44 after passing through the horizontal track unit 41, and ascends into another horizontal track unit 41 through the spiral track unit 42 and continues to travel to the target area. Thus, the transfer device 5 can move up and down in the three-dimensional space of the restaurant, thereby transferring the article to a specific position of the restaurant. Since the conveyor 5 is driven by power, climbing can be completed without external force, and noise generated when sliding by gravity can be reduced. Alternatively, a table and a seat may be provided below the spiral track unit 42, and the conveyor 5 stops when it reaches a position below the spiral track unit, and the customer takes the article out of the conveyor 5. Alternatively, a table and seats may be provided in a space formed between the ascending rail unit 43 and the descending rail unit 44, and the conveyor 5 transfers the articles to an adjacent dining table from which the customers or attendants can take the articles. Alternatively, a passageway, which may also be called a line of action of a restaurant, for a worker, a customer, or an automated facility to walk is provided in a space formed between the ascending rail unit 43 and the descending rail unit 44. By raising the track, the line of action of the restaurant is not cut off by the track system 4 and staff or customers can conveniently walk under the track.
The track system 4 is described in detail below. Fig. 3 illustrates a front view of a conveyor on a track system according to an embodiment of the present application. As shown in fig. 3, the track system 4 includes a first track 401 and a second track 402.
Therein, a first track 401, also referred to as guide track, is provided for cooperating with guide members of the conveyor 5 for guiding the conveyor 5 in its travel on the track system 4. The cross-section of the first rail 401 may be circular, oval, circular, square, rectangular, T-shaped, i-shaped, or U-shaped. Alternatively, the cross-section of the first track 401 may take other geometric shapes commonly used in the art, which is not limited in this application. The number of the first tracks 401 may be one (or "single") or two. Optionally, the first rail 401 may be a stainless steel circular tube, and by using the stainless steel circular tube, the weight of the rail system may be reduced, and the possibility of corrosion on the rail system may also be reduced, so that the conveying device may operate smoothly.
The second track 402, also called drive track, for transmitting low voltage direct current to the conveyor 5, cooperates with drive means of the conveyor 5 for driving the conveyor 5 in motion on the track system 4. The second track 402 may be a rack with driving teeth 4021 on the upper part, and the rack may be a flexible rack made of flexible material and precisely matched with the running gear of the transfer device 5, so that the profile of the track system can be better adapted and the driving transfer device 5 can run smoothly on the track system. The cross-section of the second track 402 may be substantially square, rectangular, T-shaped or U-shaped, except for the upper drive teeth 4021. The number of the second tracks 402 may be one (or "single") or two. The second track 402 is also provided with a conductive member 4022, and the conductive member 4022 is connected to a low voltage dc power supply, so that the low voltage dc power supply can provide a continuous power supply to the transmission device 5 through the conductive member. Alternatively, the conductive member 4022 may be a low-voltage power transmission line made of a copper wire, a flat copper wire, or the like. The voltage of the dc power supply is a low voltage, for example, 24 volts (V), which is safe and harmless to the human body. In one example, the second rail 402 includes a rack, two conductive members 4022 insulated from each other are disposed on the left and right sides of the rack, and the conductive members 4022 are respectively connected to the positive and negative electrodes of the low-voltage dc power supply. In another example, the second rail 402 comprises two racks, each rack is provided with one conductive member 4022, and the conductive members 4022 are respectively connected to the positive and negative electrodes of the low voltage dc power supply. By respectively arranging the conductive parts communicated with the positive electrode and the negative electrode of the direct-current power supply on the different second tracks 402, the insulation between the conductive parts can be better realized, and the possibility of short circuit of the conductive parts is reduced. By means of the low-voltage dc power supply, the conveyor 5 can be operated continuously on the rail system 4, so that an accidental stop of the conveyor 5 on the rail system 4 due to a battery depletion is avoided. In addition, the adoption of the low-voltage direct-current power supply can also avoid electric shock of restaurant workers and/or customers due to accidental contact with the track, and improves the safety of system operation.
The first rail 401 is provided with a support member 403 that can fixedly support the second rail 402. In some embodiments, as shown in fig. 3, the track system 4 includes two first tracks 401 and one second track 402. The first track 401 may be formed of a circular track (e.g., stainless steel tubing) made of the aforementioned track units joined end-to-end to form a closed, enclosed track, thereby connecting different areas of the restaurant. The second rail 402 may be formed by a flexible rack with driving teeth on the upper part, and a support beam 403 is provided between the first rails 401, and the support beam 403 is used for insulating and supporting the second rail 402. The support beam 403 may be U-shaped or U-shaped with a right angle, or may be "mountain" shaped or a variation of the above shape, thereby serving to support the second rail. As an example, as shown in the A-A section view of FIG. 3, the distance A between the centers of the circular cross sections of the two first rails is 220mm, the distance B between the center of the circular cross section of the first rail and the horizontal section of the support member 403 is 76mm, the diameter of the circular cross section of the first rail is phi 42mm, the thickness D of the support member 403 is 4mm, the second rail is located in the middle of the two first rails and is disposed above the support member, and the distance E between the bottom of the second rail and the horizontal section of the support member 403 is 3 mm. Those skilled in the art will appreciate that the above dimensions may be adjusted accordingly depending on the actual configuration of the track system, and the application is not limited thereto. Through setting up reasonable structural parameter, can control the cost that track system made and reformed transform, alleviate the orbital weight in space.
In other embodiments, FIG. 4 illustrates a cross-sectional view of another track system of an embodiment of the present application. As shown in fig. 4, the track system 4 includes a first track 401 and two second tracks 402. The aforementioned track units made of the first track 401 are joined end to form a closed, closed track, thereby connecting different areas of the restaurant. The second track 402 may be formed by two flexible racks with driving teeth on the upper part, and a support beam 403 extends from the lower end of the first track 401, and the support beam 403 is used for insulating and supporting the two second tracks 402. May be substantially "chevron" shaped or a variation of the above shape to act as a support for the second track. As an example, the track system may use the same or similar parameters as the previous track system, e.g. a distance of 220mm from the vertical middle line of the two second tracks, a distance of 76mm from the center of the circular cross section of the first track to the horizontal section of the support member 403, a diameter of 42mm from the circular cross section of the first track, a thickness of 4mm for the support member 403, and a distance of 3mm from the bottom of the second track to the horizontal section of the support member 403. The first rail is located in the middle of the two second rails and is disposed above the support member 403.
The conveyor 5 is described in detail below with reference to fig. 5-7, and further describes the manner in which the conveyor 5 runs on the track system 4. Fig. 5-7 show a front view, a top view and a cross-sectional view, respectively, of a conveyor according to an embodiment of the present application, as shown, the conveyor 5 includes a drive mechanism 51 and a serving trolley 52.
The driving mechanism 51 comprises a frame 510, a dc motor 511, a transmission mechanism 512, a walking gear 513, a transmission shaft 514 and a power-taking part 515. Specifically, the frame 510 is used to mount and support various components of the driving mechanism 51. The dc motor 511 is fixedly connected to the frame 510. Optionally, a motor support 517 is fixedly connected to the frame 510, and the dc motor 511 is fixedly connected to the motor support 517 and is used for supporting the operation of the dc motor 511, so that the modularization of the power part of the motor can be realized, and the maintenance and replacement of the motor are facilitated. An output shaft of the direct current motor 511 is connected with a power input end of the transmission mechanism 512, a power output end of the transmission mechanism 512 is connected with a transmission shaft 514, the transmission shaft 514 is supported on the frame 510 through a bearing and is connected with the walking gear 513, and therefore power of the direct current motor 511 is output to the walking gear 513. Alternatively, the driving shaft 514 may be supported by driving side plates 516 fixedly connected to both sides of the frame 510, thereby facilitating assembly of the driving mechanism and reducing the structural complexity of the frame 510.
The power-taking parts 515 are disposed at both sides of the frame 510. In one example, the electricity-taking component 515 is a carbon brush, two driving side plates are respectively disposed on two sides of the frame 510, and one carbon brush is fixedly connected to each driving side plate 516, and the carbon brushes respectively communicate with the two conductive components 4022 on the second rail 402, so as to take electricity from the conductive components. In the example of the single second rail shown in fig. 3, carbon brushes on both sides of the drive mechanism communicate with conductive members that are insulated from each other and disposed on both sides of the second rail 402, respectively. In the foregoing example of the two second rails 402, two carbon brushes communicate with the conductive members provided on the two second rails 402, respectively. In other examples, the electricity-taking component 515 may be another type of electricity-taking component, such as a carbon brush or an elastic conductive sheet directly led out from two sides of the frame 510 of the conveying device 5, so as to take electricity from the conductive component of the second rail 402. Alternatively, in order to keep the carbon brush in contact with the conductive member, an elastic force may be applied to the carbon brush toward the conductive member, for example, by a spring, to avoid poor contact of the carbon brush with the conductive member.
The traveling gear 513 is engaged with the driving teeth of the second rail 402, so that when the traveling gear 518 rotates, the driving mechanism 51 is pushed by the engaged driving teeth to move along the rail, thereby driving the conveyor 5 to run on the rail system 4. It should be understood that the above-mentioned connecting structure may include corresponding connecting components, such as screws, bolts, nuts, bearings, etc., which may be general components in the art, and will not be described in detail herein. Alternatively, the dc motor may be a dc servo motor. When the conveyor 5 is running on the track system, the current-taking part 515 takes direct current from the conductive part of the second track 402, thereby providing a power supply to the direct current motor 511.
An output shaft of the direct current motor 511 is connected with a power input end of the transmission mechanism 512, a power output end of the transmission mechanism 512 is connected with a transmission shaft 514, and the transmission shaft 514 is connected with the walking gear 513, so that the power of the direct current motor 511 is output to the walking gear 513. The traveling gear 513 is engaged with the driving teeth of the second rail 402, so that when the traveling gear 518 rotates, the driving mechanism 51 is pushed by the engaged driving teeth to move along the rail, thereby driving the conveyor 5 to run on the rail system 4. It should be understood that the above-mentioned connecting structure may include corresponding connecting components, such as screws, bolts, nuts, bearings, etc., which may be general components in the art, and will not be described in detail herein. Alternatively, the dc motor may be a dc servo motor. When the conveyor 5 is running on the track system, the current-taking part 515 takes direct current from the conductive part of the second track 402, thereby providing a power supply to the direct current motor 511.

Alternatively, the transfer device 5 may take other configurations. In some embodiments, the drive mechanism 51 and the serving trolley 52 of the conveyor 5 may be integral. That is, the serving cart 52 may not be additionally provided. The structure of the drive mechanism 51 may be substantially identical to that of the drive mechanism described above, with the guide member 523 on the traction bracket being provided to the frame 510. Specifically, guide members 523 are provided at both sides of the housing 510. The guide member 523 may be movably coupled to the frame 510 by a rotation shaft so that when the conveyor 5 travels to a loop or curve of the track system 4, the guide member 523 may rotate relative to the frame 510 to better accommodate the loop or curve.

The bracket 522 has the same function and function as the bracket described above except that the bottom shape is adapted to the frame 510, and thus, the description thereof is omitted. Thus, the combination of the powered drive mechanism 21 and the unpowered serving trolley 52, which may also be referred to as a powered serving trolley, may result in a more compact configuration of the conveyor 5. In other embodiments, the powered serving carts and the unpowered serving carts may be grouped in different numbers to transport various types of articles. It should be noted that the grouping of the powered serving trolley and the unpowered serving trolley is realized by the connection of the driving mechanism bracket and the traction bracket, and the specific structure can refer to the foregoing description, and is not described herein again.
The positioning device of the conveyor and its operation will be described with reference to fig. 8. Fig. 8 shows a schematic view of the positioning operation of the transport device on the rail system. The conveying device comprises a positioning device, the positioning device acquires corresponding position information on the track system and sends the position information to a main controller of the conveying device, and the main controller controls the running speed of the conveying device according to the position information, such as acceleration, deceleration, continuous running or stopping.
In one embodiment, the positioning device of the conveying device may be a radio frequency positioning device, which may be a radio frequency card reader. One or more radio frequency tags (e.g., N tags) are disposed on the transfer track of the track system. The radio frequency tag can be arranged on the conveying track or on the track support, so that when the radio frequency card reader approaches the radio frequency tag, the information on the radio frequency tag can be scanned through the radio frequency card reader. The radio frequency tags may correspond one-to-one with specific location points on the track system, thereby identifying location information for these specific location points. As shown in fig. 8, radio frequency tags T1, T2, T3 … … Tn may be disposed on a transport track beside a table or a seat to identify position information of the table or the seat. For simplicity of description, fig. 8 shows only the table and seat corresponding to the rf tag T2, so that the tag T2 can uniquely identify the table and seat there. Alternatively, the rf tag may be positioned slightly forward of the track, thereby providing a suitable stopping distance for the conveyor to rest at the table or seat. During the operation of the conveyors V1-V3, the radio frequency card reader can scan the radio frequency tags T1-T3 to obtain the ID information of the radio frequency tags.
In another embodiment, the positioning device of the transport device may be an optical positioning device, which may be an optical sensor. One or more optical labels (e.g., N labels) are disposed on the transport track of the track system. The optical label can be arranged on the inner side of the conveying track or on the track support, and the pattern or the figure on the optical label faces the optical sensor, so that the pattern or the figure on the optical label can be scanned by the optical sensor. The optical labels may have a one-to-one correspondence with specific location points on the track system, thereby identifying location information for these specific location points. The location distribution of the optical tags T1, T2, T3 … … Tn on the tracks can refer to the above distribution of the rf tags, which is not described herein again.
The following description will proceed to the positioning operation of the transmitting device by taking the rf positioning device as an example. As shown in fig. 8, when a customer sits at a dining table or a seat identified by the rf tag, the information of the food and/or beverage ordered by the customer and the rf tag T2 is returned to the main control device of the restaurant along with the order, and the food and/or beverage and the information of the rf tag T2 form a corresponding relationship. The order can be completed through handwritten records of staff, and can also be completed through ordering equipment placed on each dining table or seat. The ordering device can be any known type of intelligent terminal, such as a mobile phone, a tablet computer and the like; the main control device of the restaurant may be a server or an intelligent terminal of a known type, which is not limited in this application. With the ordering device, the order can be generated immediately after the order of food and/or beverage is finished, so that the ordering efficiency and accuracy of the customer can be improved. It should be noted that the number of the dining table or the seat, the ID of the ordering device placed on the dining table or the seat, and the ID of the tag at the track position beside the dining table or the seat are in a one-to-one correspondence relationship, and the correspondence relationship may be stored in the main control device of the dining table or in each transport device, so that the correspondence relationship may be called at any time when needed. To reduce the complexity of the description, the present application will be described with a "tag", it being understood that the tag is positionally corresponding to a table or a seat, and an ordering device placed on the table or the seat.
For the dishes ordered by the customer of the rf tag 2, after the kitchen of the restaurant finishes cooking or prepares food and/or beverage, a dish tag may be attached to the outer package of the food and/or beverage, and the information of the dish tag corresponds to the information of the rf tag T2, which may be obtained from the aforementioned order. Before or when food and/or beverage is put into the conveying device, the conveying device scans the dish label through the radio frequency card reader, so that the information of the target position label is obtained and stored in the conveying device. In fig. 8, at least three conveyors V1, V2 and V3 run on the track system. Food and/or beverages may be placed in any of the three conveyors described above. Taking food and/or beverage to be placed into the conveying device V2 as an example, after the conveying device V2 acquires and stores information of a target position tag T2, the conveying device V starts to run along a track system, sequentially scans the radio frequency tags T1 and T2, compares the acquired radio frequency tag information with the stored target position tag information (i.e., tag T2), and when the information is inconsistent, the main controller of the conveying device controls the conveying device to continue to run along the track; when the above information is in agreement, the master controller sends a stop signal to the speed controller, so as to stop the conveyor at the radio frequency tag T2, waiting for the customer to take the food and/or beverage loaded on the conveyor. Alternatively, the comparison of the information may be performed at the main control device of the restaurant, in which case the transmitting means transmits the radio frequency tag information and the stored destination location tag information to the main control device of the restaurant, which receives and compares the information and then transmits the result back to the transmitting means. Alternatively, the master or master may control the conveyor to speed up or slow down as it passes a tag at a predetermined location.
When the positioning device of the transmission device is an optical sensor, the working mode of the transmission device is similar to that of the radio frequency positioning device, and the means for scanning the label to obtain the label information is different, which is not described herein again.
In some embodiments, when the positioning device of the conveying device is a radio frequency positioning device, the dish tag may be an optical tag, in which case an optical sensor may be further disposed on the conveying device to obtain information identifying the dish tag. In other embodiments, when the positioning device of the conveying device is an optical positioning device, the dish tag may be a radio frequency tag, in which case, a radio frequency card reader may be further arranged on the conveying device to obtain information of the dish tag identification.
In other embodiments, the conveyor may be provided with a keypad entry device, and the operator may enter information about the target tag into the conveyor so that the conveyor may convey the food and/or beverage carried thereby to the location of the target tag.
Alternatively, the positioning of the conveyor can also be achieved with a simplified rail system. In one example, each conveying track corresponds to a table or a seat, only one label is arranged at the corresponding position on the conveying track, food and/or beverage can be directly placed into the conveying device, and the conveying device conveys the carried food and/or beverage to the position of the target label to stop, so that the process of scanning the dish label can be omitted. In another example, each conveying track corresponds to a table or a seat, and a brake device is arranged at a corresponding position on the conveying track and used for preventing the conveying device from moving to the position and then continuing to advance. The braking device may be a fence or similar barrier that blocks the conveyor from continuing to advance when the conveyor is operated to the corresponding position. Thereby, the structure of the transport device can be further simplified, and the transport device can be positioned at a predetermined position of the rail system. There is no need to install complicated positioning devices on the transfer device.
The conveying device can also form two or more conveying device combinations through the traction structure between the conveying devices, so that more articles can be conveyed to the target position at one time. Alternatively, the conveyor assembly may consist of the power conveyor traction unpowered conveyor described above. The unpowered conveyor may include only the necessary components for conveying articles on the tracks, such as the frame, rollers, and carriages, eliminating the drive and circuit components.
