The present invention relates to a custom food and drink transport device.

In recent years, in restaurants, a device for automatically transporting food and drink prepared by receiving an order on a transport tray has been used (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2011-161558

There are various types of transport devices that transport ordered food and drink, but basically all of them transport containers such as plates, vessels, mugs, and bowls on which food and drink are placed on trays or conveyors. It is difficult to place a container that does not fit on a tray or conveyor. Therefore, at the restaurant where the custom-made food and drink transport device is installed, a model corresponding to the type of food and drink handled at the restaurant is selected.

By the way, in recent years, restaurants have become larger with the development of the restaurant industry, and it is required to efficiently transport ordered foods and drinks to each audience seat by a transport device. In addition, with the diversification of customer needs, it is also required to provide food and drink using containers of various sizes. However, it is difficult to place a container of a size that does not fit on the transport tray of the conventional custom-made food and drink transport device, so if you want to be able to provide food and drink using containers of various sizes. A custom food and drink transport device equipped with a large transport tray will be selected. However, a custom-made food and drink transport device equipped with a large transport tray requires more installation space than a device equipped with a small transport tray, and when a small container is placed on a large transport tray for transport, it is transported. Empty space is created in the tray and the transport efficiency is reduced.

Therefore, the present application discloses a custom-made food and drink transport device capable of transporting containers of various sizes and enhancing transport efficiency.

In order to solve the above problems, in the present invention, a plurality of transport lanes on which the transport trays on which the containers for ordered food and drink are placed are formed in parallel, and the control device for controlling the travel of the transport trays is in an asynchronous mode. In, each transport tray was run independently of each other, and in the synchronous mode, each transport tray was run in parallel.

Specifically, it is an order food and drink transport device that transports order food and drink between the kitchen of the restaurant and the audience seat area, and each transport tray on which the order food and drink ordered by the customer in the audience seat area runs. Controls the running of a plurality of transport lanes in which the routes from the kitchen to at least one of the passenger seats in the audience seat area are formed in parallel with each other, and the travel of each transport tray in the plurality of transport lanes. In the asynchronous mode selected when transporting a container of ordered food and drink of a size that can be placed on one transport tray, the control device accepts a designated operation of the transport destination for each transport lane. In the synchronous mode selected when each transport tray of a plurality of transport lanes is run independently of each other and a container of ordered food or drink having a size straddling between the plurality of transport lanes is transported, a transport destination designation operation is performed. Is accepted and each transport tray of a plurality of transport lanes is run in parallel.

With the above-mentioned ordered food and drink transport device, since the transport trays can be independently run in the asynchronous mode, it is possible to respond to orders for food and drink from various tables. In addition, since the transport trays run in parallel in the synchronous mode, if you want to transport a large container that cannot survive in any one of the multiple transport trays, you can place the container so that it straddles the multiple transport trays. it can. Therefore, the above-mentioned custom-made food and drink transport device can transport food and drink placed in containers of various sizes, but is as many as the custom-made food and drink transport device equipped with a large transport tray. It does not require an installation space for the container and does not cause a decrease in transfer efficiency as in the case where a small container is placed on a large transfer tray and transported.

Further, the plurality of transport lanes have ribs that guide the course of the transport tray along the center line of the transport lane, and each transport tray has a plurality of rollers that sandwich the ribs from both sides at the center of each. It may have. If the transport trays are guided by ribs formed along the center line of the transport lanes, the distance between the transport trays is kept constant at the curved portion of the transport lanes in the synchronous mode.

Further, the plurality of transport lanes have a curved portion while being parallel to each other, and in the synchronous mode, the control device maintains the parallel running state of each transport tray while traveling on the curved portion of each transport tray. Therefore, the speed of the transport tray traveling on the inner peripheral side in the curved portion may be slower than the speed of the transport tray traveling on the outer peripheral side in the curved portion. If the transport trays of each transport lane are controlled in this way, the transport trays of each transport lane run in parallel even in the curved portion of the transport lane. Therefore, for example, the container is straddled over a plurality of transport trays. Even if it is listed, it is unlikely that the container will be dropped at the curved part.

Further, the transport lane is formed by rotating the belt in a state where the connected means provided at the center of the transport tray is connected to the connecting means attached to the belt extending along the center line of the transport lane. The control device has a drive mechanism for traveling the transport tray, and in the synchronous mode, the control device sets the speed of the belt that moves the transport tray traveling on the inner peripheral side in the curved portion, and the transport path on the outer peripheral side in the curved portion. The speed may be reduced by an amount corresponding to the ratio of the radius of the curve to the transport path on the inner peripheral side. The difference in path length between the outer peripheral side and the inner peripheral side in the curved portion is proportional to the radius of the arc that draws the center line of the transport lane. Therefore, when the transport tray travels following the belt extending along the center line of the transport lane, the speed of the belt that moves the transport tray traveling on the inner peripheral side in the curved portion is set to the transport path on the outer peripheral side. By decelerating by an amount corresponding to the ratio of the radius of the curve to the transport path on the inner peripheral side, the transport trays of each transport lane can be easily run in parallel even in the curved portion.

With the above-mentioned custom-made food and drink transport device, containers of various sizes can be transported and the transport efficiency can be improved.

Hereinafter, embodiments of the present invention will be described. The embodiments shown below are one aspect of the present invention and do not limit the technical scope of the present invention. Each of the embodiments and modifications shown below is suitable for restaurants that provide various foods and drinks such as sushi and beverages, rice bowls such as soba and udon, and fried chicken and tempura.

FIG. 1 is a diagram showing an ordered food and drink transport device according to an embodiment. The ordered food and drink transport device 1 is a device that transports food and drink prepared in response to a customer's order from the kitchen 7 to the tables 2a1 to 4 and 2b1 to 4, and as shown in FIG. 1, each table 2a1 to It includes two transport lanes 3a and 3b having center lines parallel to each other along 4, 2b1 to 4, and transport trays 4a and 4b capable of traveling on the respective transport lanes 3a and 3b. The distance between the two parallel transport lanes 3a and 3b is such that the transport tray 4a traveling on the transport lane 3a and the transport tray 4b traveling on the transport lane 3b are arranged in parallel between the transport tray 4a and the transport tray 4b. It is installed so that there is almost no gap between them. The order food and drink transport device 1 accepts orders via the touch panels 5a1 to 4,5b1 to 4 installed on the tables 2a1 to 4, 2b1 to 4. Then, when the staff of the kitchen 7 who prepared the ordered food and drink operates the operation panel 6, the ordered food and drink transport device 1 puts the prepared food and drink on the touch panel 5a1 which received the order of the food and drink. To the positions of the tables 2a1 to 4, 2b1 to 4 on which ~ 4,5b1 to 4 are installed, the transfer trays 4a and 4b are used for transportation.

Hereinafter, details of the respective transport lanes 3a and 3b will be described. Since the transport lanes 3a and 3b all have the same internal structure, they will be described below with the same reference numerals. FIG. 2 is a view of the internal structure of each transport lane 3 (3a, 3b) as viewed from above. Further, FIG. 3 is a cross-sectional view when the transport lane 3 is cut along the line of reference numerals AA shown in FIG.

The transport lane 3 is provided with various mechanisms for running the transport trays 4 (4a, 4b). That is, the transport lane 3 is provided with a drive belt 32 extending along the longitudinal direction of the transport lane 3 on the lower side of the transport path plate 31 on which the transport tray 4 is placed. The drive belt 32 is hung on two pulleys 33S and 33E provided at both ends in the longitudinal direction of the transport lane 3, and a tension adjusting mechanism (not shown) provided on any one of the two pulleys 33S and 33E. Appropriate tension is given by. Further, one of the two pulleys 33S and 33E is connected to a drive motor (not shown). When the drive motor operates, the drive belt 32 spanned by the two pulleys 33S and 33E is rotationally driven clockwise and counterclockwise. The drive motor that rotationally drives the drive belt 32 is a stepping motor, and can rotationally drive the drive belt 32 at a rotational speed and a rotational amount according to a control signal of the control device.

A belt bracket 34 is attached to a predetermined position of the drive belt 32. The belt bracket 34 is a first magnetic body 35 that is magnetically connected to the transport tray 4 (an example of the “connecting means” in the present application), and a transport groove 36 that extends in the longitudinal direction provided in the transport path plate 31. It has guide rollers 38, 38 that prevent the belt bracket 34 from swinging in the left-right direction while rolling on the wall surfaces of both side walls 37, 37. The belt bracket 34 moves along the transport lane 3 following the rotational drive of the drive belt 32.

The drive belt 32 is guided by sliding rollers 32L and 32R arranged along the track of the curved transport lane 3 at the corner portion where the transport lane 3 curves. By guiding the drive belt 32 by the sliding rollers 32L and 32R, the belt bracket 34 can be smoothly moved along the curve of the corner portion of the transport lane 3 even at the corner portion of the transport lane 3.

Next, the details of the transport trays 4a and 4b will be described. Since the transport trays 4a and 4b all have the same internal structure, they will be described below with the same reference numerals. FIG. 4 is a view of the transport tray 4 as viewed from below. Further, FIG. 5 is a cross-sectional view when the transport tray 4 is cut along the line of reference numeral BB shown in FIG.

The transport tray 4 is provided with wheels for traveling in the transport lane 3, connecting means for magnetically connecting to the first magnetic body 35 of the belt bracket 34, and the like. For example, the transport tray 4 is provided with a resin tray body 41 on which food and drink can be placed on the upper surface side, and a base 42 having a rectangular shape when viewed from above, which supports the tray body 41. Further, universal wheels 43 whose steering angle can be changed are provided at the four corners of the base 42, and fixed wheels 44 whose steering angle cannot be changed are provided on both left and right sides of the central portion of the base 42. The transport tray 4 is supported by six wheels capable of stable traveling.

A second magnetic body 45 (an example of the "coupled means" referred to in the present application) that is magnetically connected to the first magnetic body 35 is provided in the central portion of the base 42. One of the first magnetic body 35 and the second magnetic body 45 may be a ferromagnet, and one of them may be a permanent magnet, or both may be a permanent magnet.

Further, support rollers 46L1, 46R1, 46L2, 46R2 are provided on both the left and right sides of the second magnetic body 45. The support roller 46L1 and the support roller 46R1 are symmetrically attached to the base 42 at the same interval as the width of the rib 31R protruding toward the upper surface side of the transport path plate 31. Like the support roller 46L1 and the support roller 46R1, the support roller 46L2 and the support roller 46R2 are also symmetrically attached to the base 42 at the same interval as the width of the rib 31R. The support rollers 46L1 and the support rollers 46L2 are lined up along the front-rear direction (traveling direction) of the transport tray 4. The support rollers 46R1 and the support rollers 46R2 are also arranged along the front-rear direction of the transport tray 4 in the same manner as the support rollers 46L1 and the support rollers 46L2. Therefore, when the transport tray 4 is placed on the transport lane 3, the rib 31R is sandwiched between the support roller 46L1 and the support roller 46R1 slightly in front of the center of the transport tray 4, and from the center of the transport tray 4. The rib 31R is sandwiched between the support roller 46L2 and the support roller 46R2 slightly behind the tray. As a result, the traveling path and direction of the transport tray 4 are regulated by the rib 31R, and the transport tray 4 travels while aligning the directions along the longitudinal direction of the rib 31R. For example, the transport tray 4 faces the front along the longitudinal direction of the transport lane 3 in the straight portion of the transport lane 3, and left or right along the curvature of the corner portion of the transport lane 3 in the corner portion of the transport lane 3. Suitable for.

The tray body 41 is formed with a mounting surface 41S for mounting a container for food and drink, and by mounting the container on the mounting surface 41S, the container can be held without dropping from the tray body 41. ing. In the tray body 41, for example, the mounting surface 41S is formed of a member having a relatively high coefficient of friction so that the container does not slip off. The tray body 41 is not limited to a tray body 41 having a mounting surface 41S formed flat by a member having a relatively high coefficient of friction. The tray body 41 may have a recess formed in place of the flat mounting surface 41S, for example.

The control device that controls the movement of the transport trays 4a and 4b has two operation modes, an asynchronous mode and a synchronous mode. The mode can be switched by the operation panel 6 provided in the kitchen 7. Hereinafter, the movements of the transport trays 4a and 4b in each mode will be described.

FIG. 6 is a first diagram showing an operating state of the ordered food and drink transport device 1. When the asynchronous mode is selected, the order food and drink transport device 1 moves the transport tray 4a and the transport tray 4b separately. That is, in the above-mentioned ordered food and drink transport device 1, for example, when the food and drink ordered via the touch panel 5a4 installed on the table 2a4 is prepared by the staff and the operation panel 6 of the kitchen 7 is operated, the transport lane The drive belt 32 of 3a rotates and the transport tray 4a moves from the kitchen 7 to the table 2a4 (see FIG. 6A). Then, when the food and drink customer removes the food and drink container placed on the transport tray 4a from the transport tray 4a, the drive belt 32 of the transport lane 3a rotates in the opposite direction, and the transport tray 4a moves from the table 2a4 to the kitchen 7 ( (See FIG. 6B). The same applies when an order is placed on the other tables 2a1 to 3 and 2b1 to 4, and the order food and drink transport device 1 uses, for example, the transport tray 4a as the kitchen 7 when the order is placed on the touch panel 5a1. Reciprocate to and from the table 2a1.

FIG. 7 is a second diagram showing an operating state of the ordered food and drink transport device 1. When the synchronous mode is selected, the order food and drink transport device 1 moves the transport tray 4a and the transport tray 4b at the same time. That is, in the above-mentioned ordered food and drink transport device 1, for example, when the food and drink ordered via the touch panel 5a1 installed on the table 2a1 is prepared by the staff and the operation panel 6 of the kitchen 7 is operated, the transport lane The drive belts 32 of 3a and the transport lane 3b rotate at the same speed, and the transport tray 4a and the transport tray 4b move in parallel from the kitchen 7 to the table 2a1 (see FIG. 7A). Then, when the food and drink removes the large container straddling the transport trays 4a and 4b from the transport trays 4a and 4b, the drive belts 32 of the transport lane 3a and the transport lane 3b rotate in opposite directions at the same speed. The transport trays 4a and 4b move from the table 2a1 to the kitchen 7 (see FIG. 7B). The same applies when an order is placed on the other tables 2a2 to 4, 2b1 to 4, and the ordered food and drink transport device 1 uses the transport trays 4a and 4b in the kitchen when the order is placed on the touch panel 5a2, for example. When the 7 and the table 2a2 are reciprocated and an order is placed on the touch panel 5b1, the transport trays 4a and 4b are reciprocated between the kitchen 7 and the table 2b1 and the order is placed on the touch panel 5b2. Moves the transport trays 4a and 4b back and forth between the kitchen 7 and the table 2b2.

In the asynchronous mode, the transport trays 4a and 4b can be run independently, so that it is possible to quickly respond to orders for food and drink from various tables. Further, since the transport trays 4a and 4b run in parallel in the synchronous mode, when it is desired to transport a large container that cannot survive in either of the transport trays 4a and 4b, the loading surface 41S and the transport tray 4b of the transport tray 4a The container can be placed so as to straddle the mounting surface 41S of. Therefore, for example, in a conveyor belt sushi restaurant, when about two pieces of sushi are placed on a plate and transported, they are operated in an asynchronous mode. In addition, when it is desired to transport dozens of pieces of sushi together, or when various foods and drinks other than sushi that require a platter are transported, the operation is performed in the synchronous mode. The custom-made food and drink transport device 1 of the present embodiment can provide food and drink using containers of various sizes, but has many installation spaces like the custom-made food and drink transport device equipped with a large tray. It does not require a small amount of the container and does not cause a decrease in transportation efficiency as in the case where a small amount of a small container is placed on a large tray and transported.

By the way, since there is no corner portion between the kitchen 7 and the tables 2a1 to 2 and 2b1 and 2, in the case of the synchronous mode, when reciprocating between the kitchen 7 and the tables 2a1 and 22b1 and 2 , The control device may simply rotate each drive belt 32 of the transport lane 3a and the transport lane 3b at the same speed. However, since there is a corner portion between the kitchen 7 and each of the tables 2a3 to 4, 2b3 to 4, if the control device simply turns each drive belt 32 of the transport lane 3a and the transport lane 3b at the same speed, the corner portion Due to the difference between the path length of the transport lane 3a on the outer peripheral side and the path length of the transport lane 3b on the inner peripheral side, a positional shift occurs between the transport tray 4a and the transport tray 4b. Therefore, when the transport trays 4a and 4b reciprocate between the kitchen 7 and the tables 2a3 to 4, 2b3 to 4 in the state where the synchronization mode is selected, the control device is connected to the drive belt 32 of the transport lane 3a. The rotational drive of the drive belt 32 of the transport lane 3b is controlled as follows.

FIG. 8 is a diagram showing an example of a processing flow executed when the control device of the ordered food / drink transport device 1 is moving the transport trays 4a and 4b in a state where the synchronization mode is selected. When the operation panel 6 is operated in the state where the synchronization mode is selected and the traveling of the transport trays 4a and 4b is started, the control device of the order food and drink transport device 1 executes the following processing.

That is, the control device of the ordered food and drink transport device 1 specifies the current positions of the transport trays 4a and 4b from the number of pulses of the drive motor while the transport trays 4a and 4b are traveling. Then, the control device of the ordered food and drink transport device 1 determines whether or not the current positions of the transport trays 4a and 4b are at the corners of the transport lanes 3a and 3b (S101). When a positive determination is made in the process of step S101, the control device of the ordered food and drink transport device 1 drives two drives, a drive motor that rotates the drive belt 32 of the transport lane 3a and a drive motor that rotates the drive belt 32 of the transport lane 3b. Among the motors, the drive motor that rotates the drive belt 32 of the transport path on the inner peripheral side at the corner portion is changed to reduce the speed (S102). The shift amount depends on the ratio of the radius of the curve of the transport lane 3a to the radius of the curve of the transport lane 3b at the corner portion. For example, if the radius of the curve of the transport path on the inner peripheral side is half the radius of the curve of the transport path on the outer peripheral side, the control device of the ordered food and drink transport device 1 is on the inner peripheral side in the process of step S102. The speed of the drive motor that rotates the drive belt 32 of the transport path is halved. The speed change amount and the position of the corner portion are preset in the control device when the custom food and drink transport device 1 is installed. After performing the process of step S102, the control device of the ordered food and drink transport device 1 determines whether or not the current positions of the transport trays 4a and 4b are in the straight portions of the transport lanes 3a and 3b (S103). .. When the control device of the order food and drink transport device 1 makes an affirmative determination in the process of step S103, the control device recovers the speed of the drive motor that has changed gears in the process of step S102 (S104).

FIG. 9 is a diagram showing a traveling state of the transport trays 4a and 4b at the corner portion when the synchronization mode is selected. The control device of the order food and drink transport device 1 repeatedly executes the series of processes from step S101 to step S104 above while the transport trays 4a and 4b are running in the state where the synchronization mode is selected. While the transport trays 4a and 4b are running in the synchronous mode, the series of processes from step S101 to step S104 is repeatedly executed between the kitchen 7 and the tables 2a3 to 4, 2b3 to 4. Even when the transport trays 4a and 4b reciprocate, there is no misalignment between the transport tray 4a and the transport tray 4b at the corners where the path lengths are different. As a result, the container can be safely transported from the kitchen 7 to each of the tables 2a3 to 4, 2b3 to 4 without causing the container to fall due to the misalignment between the transport tray 4a and the transport tray 4b.

In the above embodiment, the free wheels 43 are provided at the four corners of the transport tray 4 so that the corners can be smoothly bent. However, the custom-made food and drink transport device 1 of the above embodiment is not limited to such an embodiment. The custom-made food and drink transport device 1 is, for example,
Food and drink may be transported by a transport tray provided with a mechanism for adjusting the steering angle of the wheels according to the course of the transport lanes 3a and 3b.

FIG. 10 is a bottom view of a modified transport tray provided with a mechanism for adjusting the steering angle of the wheels according to the paths of the transport lanes 3a and 3b. In the description of the transport tray 4A according to this modification, the same reference numerals are given to the same configurations as the transport tray 4 of the above embodiment, and detailed description thereof will be omitted. Similar to the transport tray 4 of the above embodiment, the transport tray 4A according to this modification includes wheels for traveling in the transport lane 3, a mechanism for magnetically connecting to the first magnetic body 35 of the belt bracket 34, and the like. Is provided. For example, the transport tray 4A is provided with a tray body 41 and a base 42. Further, fixed wheels 44 whose steering angle cannot be changed are provided on both left and right sides of the central portion of the base 42. A second magnetic body 45 is provided at the center of the base 42, and support rollers 46L1, 46R1, 46L2, 46R2 are provided on the left and right sides of the second magnetic body 45.

Movable plates 47 arranged along the lower surface of the base 42 are provided at both ends of the base 42 along the traveling direction. The movable plate 47 is an elongated plate-shaped member extending to both left and right sides in the traveling direction of the base 42, and fixed wheels 44A are provided at both ends thereof. Ball casters 48, 48 are provided near each of the two fixed wheels 44A at both ends of the movable plate 47 so that the balls come into contact with the lower surface of the base 42. Further, at the center of the movable plate 47, one end of the link 49 rotatably attached to the base 42 by the bolt 49K is rotatably attached to the other end of the link 49 by the bolt 49J. Therefore, the movable plate 47 can freely move along the lower surface of the base 42 within the range of the movable region regulated by the link 49. The movable plate 47 is provided with four support rollers 46AL1, 46AR1, 46AL2, 46AR2 so as to sandwich the central portion of the movable plate 47 from both the left and right sides.

The support roller 46AL1 and the support roller 46AR1 are symmetrically attached to the movable plate 47 at the same interval as the width of the rib 31R protruding toward the upper surface side of the transport lane 3. Like the support roller 46AL1 and the support roller 46AR1, the support roller 46AL2 and the support roller 46AR2 are symmetrically attached to the movable plate 47 at the same interval as the width of the rib 31R. The support roller 46AL1 and the support roller 46AL2 are lined up along the front-rear direction of the transport tray 4. The support rollers 46AR1 and the support rollers 46AR2 are also arranged along the front-rear direction of the transport tray 4 in the same manner as the support rollers 46AL1 and the support rollers 46AL2. Therefore, when the transport tray 4 is placed on the transport lane 3, the rib 31R is sandwiched between the support roller 46AL1 and the support roller 46AR1 slightly in front of the center of the movable plate 47, and from the center of the movable plate 47. The rib 31R is sandwiched between the support roller 46AL2 and the support roller 46AR2 slightly behind the support roller 46AL2. As a result, the direction of the movable plate 47 is adjusted following the rib 31R, and when the transport tray 4A travels in the transport lane 3, the movable plate 47 travels while aligning the directions along the longitudinal direction of the rib 31R. .. That is, the orientation of the fixed wheels 44A fixed to the movable plate 47 is automatically adjusted toward the traveling direction of the transport tray 4A. For example, at the corner portion of the transport lane 3, the fixed wheel 44A fixed to the movable plate 47 faces left or right along the curvature of the corner portion of the transport lane 3.

FIG. 11 is a diagram showing the behavior of the movable plate 47 when the transport tray 4A according to the modified example travels on the corner portion of the transport lane 3. When the movable plate 47 of the transport tray 4A traveling in the corner portion of the transport lane 3 enters the corner portion of the transport lane 3, the direction of the movable plate 47 changes according to the curvature of the rib 31R of the corner portion, and the fixed wheel 44A The steering angle is adjusted to follow the curvature of the corner portion (see FIG. 11 (A)). However, since the orientation of the base 42 is adjusted by the support rollers 46L1, 46R1, 46L2, 46R2, the orientation of the base 42 is before the central portion of the base 42 enters the corner portion of the transport lane 3. Does not change. Therefore, when the movable plate 47 enters the corner portion of the transport lane 3, the link 49 rotates slightly around the bolt 49K (see FIG. 11B). Then, when the central portion of the base 42 enters the corner portion of the transport lane 3, the orientation of the base 42 also changes (see FIG. 11C). Then, when the transport tray 4 passes through the corner portion of the transport lane 3, the orientation of the movable plate 47 and the base 42 returns to the original orientation (see FIG. 11 (D)).

In the case of the transport tray 4A according to this modification, the rudder angles of the support rollers 46AL1, 46AR1, 46AL2, 46AR2 that support the transport tray 4A at the four corners of the transport tray 4A are adjusted to follow the course of the transport lane 3. Therefore, it is possible to smoothly turn at the corner portion of the transport lane 3.

The custom-made food and drink transport device 1 of the above embodiment is not limited to the one including two transport lanes 3a and 3b whose center lines are parallel to each other. The custom-made food and drink transport device 1 may include three or more transport paths. When the custom-made food and drink transport device 1 is provided with three or more transport paths, three or more transport trays may be run in parallel, or some of the three or more transport trays may be run in parallel. , Other transport trays may be run independently.

Further, the ordered food and drink transport device 1 of the above embodiment is not limited to the one that transports food and drink to the table seat. The order food and drink transport device 1 may transport food and drink to counter seats in addition to table seats.

Further, the custom-made food and drink transport device 1 of the above embodiment may be provided with not only one stage of a plurality of parallel transport paths but also a plurality of stages vertically.
