Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dish stacking apparatus for reading information on a dish after a customer has eaten it in a store where a rotating dining table is installed, stacking the dish after reading the information in one place, and a dish stacking apparatus. It relates to the rotating dining table system used.

[0002]

2. Description of the Related Art In recent years, stores equipped with a revolving dining table, such as those found in revolving sushi restaurants, have been booming. Such a rotary dining table has a basic configuration of a conveyor that rotates a predetermined range along a counter where a plurality of customers are arranged, and dishes arranged on the conveyor, for example, dishes on which sushi is placed. It is structured so that it can be transported along the counter. Therefore, the customer at the counter takes the plate on which the favorite sushi is placed from the conveyor, and after eating the sushi, stacks the plate on the counter, and the price is determined according to the type of plate, so accounting is done Occasionally, a store clerk calculates the total amount of sales based on the number of dishes for each type of dishes stacked on a counter and performs an accounting process.

[0003] As described above, in a store provided with a rotating dining table, it is common practice for a clerk to determine the number and type of dishes after a customer has eaten. On the other hand, there has conventionally been an invention in which information on a dish after a customer has eaten is automatically determined. For example,
In Japanese Patent Application Laid-Open No. 5-42787, a tableware insertion port for dropping dishes onto a belt conveyor arranged in the counter is provided on the counter, and the number of dishes put into the tableware insertion port is turned on based on the passage of the dishes. The invention is described in which counting is performed by a signal from a switch. In the case of the present invention, since the number of plates can be measured but the type of the plates cannot be determined, all the plates can be determined, as described in Japanese Utility Model Publication No. 55-42787 (4th column, lines 19 to 20). It is assumed that the price of the sushi on the plate is the same. On the other hand, Japanese Patent Application Laid-Open No. Sho 63-5492 replaces the microswitch of the invention described in Japanese Utility Model Publication No. 55-42787 with an optical sensor that reads a bar code, color code or magnetic code attached to a plate. Invention is disclosed. Also, in Japanese Patent Application Laid-Open No. 8-238160, an ID medium which is an electromagnetic derivative is attached to a dish,
I attached to a dish stacked in place on the counter
An invention is disclosed in which information on a D medium is read by a reading sensor.

[0004]

First, in a store provided with a rotating dining table, it is desirable to stack dishes after eating by a customer at a predetermined position corresponding to the customer, preferably near the customer. There is a request. This is because the dish after the customer eats is not in a predetermined position.
As described in JP-A-87-87 and JP-A-63-5492, if the plates after being conveyed by a belt conveyor and eaten by each customer are mixed, it is assumed that the number of sheets eaten during the accounting process. This is because there is no coping method when a serious trouble occurs. For this reason,
The structure described in Japanese Patent Application Laid-Open No. 2787 and Japanese Patent Application Laid-Open No. 63-5492 is not suitable for a store equipped with a rotating dining table.

[0005] Second, in a store equipped with a rotating dining table, when a customer determines the number and type of dishes after eating,
There is a demand to prevent fraud. This is based on the fact that the number and type of dishes are often underreported when a clerk's friend comes to the store. In this regard, in the invention disclosed in Japanese Patent Application Laid-Open No. H8-23816, dishes are stacked near the customer on the counter, so that not only fraud by the clerk but also fraud by the customer is possible, which is not desirable.

Third, in a store provided with a rotating dining table, there is a demand for reducing the unit price of dishes when implementing a system for counting the number of dishes after eating by customers. This seems to be a natural request since the number of plates used in one store is considerable.
In this regard, in the invention disclosed in Japanese Patent Application Laid-Open No. H8-23816, in which an ID medium which is an electromagnetic derivative is attached to a dish, the price of the dish must be increased, which is not desirable. In addition,
Japanese Patent Application Laid-Open No. 8-23816 discloses that an ID medium attached to a plate may be a barcode (column 6, lines 36 to 38). It is completely unknown how to read the information of the ID medium.

[0007] Fourth, in a store provided with a rotating dining table, there is a demand for realizing a system for counting the number of dishes after a customer has eaten without significantly changing existing facilities. On the other hand, 55-47787
JP, JP-A-63-5492 and JP-A-8-2
In order to realize the invention described in Japanese Patent No. 3816, a substantial change of existing equipment is required, which is not desirable.

An object of the present invention is to provide a dish stacking apparatus which can satisfy all of the first, second, third and fourth needs, and a rotary eating and drinking table system provided with the same.

[0009]

According to a first aspect of the present invention, there is provided a dish stacking apparatus, wherein a first dish transport mechanism for transporting a dish from a dish placing position for placing a dish to a predetermined dish information reading position, and a dish information reading position. A rotating mechanism for rotating the plate conveyed to the
A bar code reader attached to the lower surface of the plate rotating at the plate information reading position and reading a bar code including the type information of the plate, and a second conveying the plate rotated at the plate information reading position to a predetermined plate stacking position. A dish transport mechanism and a dish stacking mechanism for sequentially stacking dishes transported to the dish stacking position are provided. Therefore, the plate placed at the placement position is transported to the plate information reading position by the first plate transport mechanism, and is rotated by the rotating mechanism. As a result, a barcode attached to the lower surface of the plate and including the type information of the plate is read by the barcode reader. This makes it possible to determine the number and type of dishes. In this case, "the lower surface of the plate" means a portion that is not the upper surface of the plate,
It is a broad concept that includes the side of the plate. Then, the dishes rotated at the dish information reading position are transported to the dish stacking position by the second dish transport mechanism, and are stacked by the dish stacking mechanism. Here, the concept of “the plate rotated at the plate information reading position” includes the concept of “the plate that has already rotated at the plate information reading position and is currently stopped” and the concept of “the plate currently rotated at the plate information reading position. Plate
And the concept of

According to a second aspect of the present invention, in the dish stacking apparatus of the first aspect, the first dish transport mechanism and the rotating mechanism are arranged in parallel with two conveyors rotating in the same direction at different peripheral speeds. And a stopper that regulates the conveyance of the plate conveyed by these conveyors at the plate information reading position. Therefore, the plates placed on the plate mounting positions on the two conveyors are transported by the two conveyors until they are closed by the stoppers, and are positioned at the plate information reading position. At this time, since the peripheral speeds of the two conveyors are different, the dish rotates at the dish information reading position. Here, various types of conveyors can be used. For example, a belt conveyor is used (claim 3).

According to a fourth aspect of the present invention, in the dish stacking apparatus of the first aspect, the second dish transport mechanism is configured to move the dish lift portion up and down in a vertical plane including the dish located at the dish information reading position. It is formed by a dish lifting mechanism that drives and conveys a dish to a dish stacking position, and the dish stacking mechanism is conveyed by raising a dish support section and a dish lift section that support the lower surface of the dish at a position lower than the dish stacking position. A retracting mechanism that retracts the plate support from the interference position immediately before the upper portion of the plate interferes with the plate support and a plate conveyed by the ascending of the plate lift portion pass through the plate support and then return to the plate support. And a return mechanism for returning to the position.
Therefore, when the dish lift of the elevating mechanism rises, the dish located at the dish information reading position is transported upward by the dish lift and positioned at the dish stacking position. On this occasion,
The ascending plate attempts to interfere with the plate support that supports the lower surface of the plate, but at the timing immediately before the upper portion of the plate supported by the plate lift interferes with the plate support, the plate support is moved by the retract mechanism. Evacuated. Thereafter, when the plate conveyed by the rise of the plate lift passes through the plate support, the plate support is returned to the original position by the return mechanism. As a result, when the plate lift unit is lowered in preparation for the conveyance of the next plate sent to the plate information reading position, the plate conveyed upward by the plate lift unit is placed below the plate already supported by the plate support unit. And is supported by the dish support.

According to a fifth aspect of the present invention, in the tray stacking apparatus, the tray is transported from a tray mounting position on which the tray is placed to a predetermined tray information reading position, and the tray transported to the tray information reading position is rotated to rotate the lower surface of the tray. The barcode including the type information of the dish attached to the tray is read by a barcode reader, and the dishes rotated at the dish information reading position are transported to a predetermined dish stacking position and sequentially stacked. Here, the concept of “the plate rotated at the plate information reading position” includes the concept of “the plate that has already rotated at the plate information reading position and is currently stopped” and the concept of “the plate that has been rotated at the plate information reading position. The concept of "a dish that is".

According to a sixth aspect of the present invention, there is provided a rotary eating and drinking table system for rotating a food transport conveyor along a counter on which a plurality of customers are arranged, and transporting a dish on which food is placed by the food transport conveyor. A table and a dish stacking device according to any one of claims 1 to 5 are provided. The dish stacking device according to any one of claims 1 to 5,
Since the present invention can be realized without remodeling an existing store having a rotating dining table, a rotating dining table system is completed simply by installing a dish stacking device on the existing rotating dining table.

[0014]

An embodiment of the present invention will be described with reference to the drawings. This embodiment is an example of a dish stacking device used as a rotating dining table system in a rotating sushi system.

FIG. 1 is a plan view showing a part of the conveyor belt sushi system. The conveyor belt sushi system includes a counter 2 on which a chair 1 is placed and a customer is arranged, and a sushi transport conveyor 5 serving as a dish transport conveyor that is disposed along the counter 2 and transports sushi 4 placed on a plate 3. , A dish stacking device 7 is installed on the counter 2. A plurality of dish stacking devices 7 are provided, and are located at the left side of the customer sitting on the chair 1 and at positions corresponding to the customers in a one-to-one relationship. Also,
The dish stacking device 7 is connected in-line to the POS terminal / ECR of the store where the conveyor belt sushi system is installed, and information on the dishes 3 after the customer has eaten, that is, the number and types of the dishes 3 and the total amount of sushi eaten. Is transmitted to the POS terminal / ECR.

FIG. 2 is a perspective view of the dish stacking device 7.
Hereinafter, the dish stacking device 7 will be described in detail.
First, the tray stacking device 7 has a tray mounting unit 10 provided with a first tray transport mechanism 9 projecting from one side surface of a housing-like main body case 8 having an open upper surface in appearance. The dish take-out basket 11 is inserted and held in the upper opening. A display 12 is provided on the front of the main body case 8 facing the customer arranged at the counter 2.
Is displayed, and the number, type and amount of dishes after the customer eats are displayed. The display on the display 12 is performed by a control operation of a control unit (not shown) of a microcomputer built in the main body case 8. The control unit controls not only the display of the display 12 but also the electrical and electronic components in the dish stacking device 7 to cause the dish stacking device 7 to perform a predetermined operation.

Next, the internal structure of the dish stacking device 7 will be described. For convenience of understanding, the tray stacking device 7
When the plate 3 is placed at the plate placing position A in the plate placing unit 10, the first plate transport mechanism 9 is driven to feed the plate 3 into the main body case 8. The plate 3 is rotated by the rotation mechanism 13 at the plate information reading position B, and the bar code BC attached to the plate 3
Is read by the bar code reader 14 (see FIG. 4). Then, the dishes 3 are sent to the dish stacking position C by the second dish transport mechanism 15, and are stacked by the dish stacking mechanism 16 (see FIGS. 5 to 8). In such a process of processing the plate 3, it is determined that the plate 3 has been placed at the plate mounting position A, for example, by providing a sensor such as an optical sensor or a microswitch in the plate mounting unit 10 and outputting an output signal thereof. Can be easily realized by a well-known method of transmitting to the control unit. Further, the detection that the plate 3 is arranged at the plate information reading position B is performed by, for example, providing a sensor such as a microswitch or a pressure sensor in the stopper 22 and transmitting an output signal thereof to the control unit. And can be easily realized.

FIG. 3 is a perspective view showing the first dish transport mechanism 9,
FIG. 4 is a perspective view showing the first dish transport mechanism 9 and the rotation mechanism 12. The first plate transport mechanism 9 provided in the plate placing unit 10 transports the plate 3 from a plate placing position A located outside the plate stacking device 7 to a plate information reading position B located therein. Are mainly formed by two belt conveyors 17 as conveyors arranged in the main body. These belt conveyors 17 have driving rollers 20 to which power is transmitted from a first motor 18 via a first gear train 19.
And a driven roller 21 rotatably supported. In the first gear train 19, since the power transmission ratios to the respective drive rollers 20 for driving the two belt conveyors 17 are different, the two belt conveyors 17 rotate at different peripheral speeds. Specifically, in FIGS. 3 and 4, the belt conveyor 17a is
The peripheral speed is faster than b. Therefore, in the present embodiment, the rotation mechanism 12 is configured using the peripheral speed difference between the two belt conveyors 17. That is, the stopper 22 is provided at a position on the inner side of the first plate transfer mechanism 9 inside the main body case 8 where the plate 3 which has been transferred by the first plate transfer mechanism 9 and has reached the plate information reading position B abuts. Are located. For this reason, the plate 3 closed by the stopper 22 is rotated by the peripheral speed difference between the two belt conveyors 17. Here, the rotation mechanism 12 is configured. In addition, on the belt conveyor 17, the plate 3 is attached to the side wall 10 a positioned on both sides of the belt conveyor 17 in the plate mounting unit 10.
Is restricted, the plate 3 is accurately positioned at the plate information reading position by the side wall 10a and the stopper 22.

Here, the stopper 22 is provided with the stopper 2
The part of the plate 3 closed by 2 is disposed at a position protruding from the first plate transfer mechanism 9. A bar code reader 14 is arranged below the plate 3 protruding from the first plate transport mechanism 9. Thereby, a plurality of barcodes BC concentrically attached to the lower surface of the plate 3 are read by the barcode reader 14 as the plate 3 rotates.
The barcode BC includes type information on the type of the dish 3. Then, the data of the barcode BC read by the barcode reader 14 is taken into the plate stacking device 7, and the plate stacking device 7 accumulates the number and types of the plates 3 and the total amount of the sushi eaten.

FIG. 5 is an exploded perspective view showing the second dish transport mechanism 15 and the dish stacking mechanism 16, and FIG.
FIG. 9 is a front view showing a movable cam 24 which is a part of a retreat mechanism 23 included in FIG. In the present embodiment, the second dish transport mechanism 15 and the dish stacking mechanism 16 are integrally formed, and the first dish transport mechanism 9 is located at the dish information reading position B.
It is arranged so that it may straddle. That is, a pair of lift hold frames 25 are provided on both sides of the first plate transport mechanism 9 with the plate information reading position B interposed therebetween. A dish lifter 27 having a plate support 26 is attached to be able to move up and down, and a dish support 29 having a dish support claw 28 as a dish support is attached to be rotatable about a horizontal axis. That is, the dish lift body 27 can be raised and lowered by the rail structure 30 between the dish lift body 27 and the lift hold frame 25, and the dish support body 29 is rotatably attached to the lift hold frame 25 by the horizontally arranged support shaft 31. I have.

Here, as a mechanism corresponding to the second dish transport mechanism 15, a cam groove 32 is horizontally cut at a lower portion of the dish lift body 27, and the second motor 3 is provided in the cam groove 32.
A driving joint 36 of a plate cam 35 to which power is transmitted from 3 via a second gear train 34 is fitted. Therefore,
The dish lift body 27 moves up and down by rotation of the plate cam 35 driven by the second motor 33. The vertical movement range is twice the distance from the center of the plate cam 35 to the prime mover 36.
Here, a dish elevating mechanism 37 is formed.

Next, as a mechanism corresponding to the dish stacking mechanism 16, the dish support 29 is provided with a lift hold frame 25.
The pair of dish supports 29 are urged in a direction approaching each other by being pressed by a leaf spring 38 as a return mechanism fixed to the plate support 38. In this case, since the lower portion of the plate support 29 abuts on the lift hold frame 25, the plate support 29 does not fall more than vertically in the biasing direction even when biased by the leaf spring 38. On the other hand, the dish support 29 is rotatable in a direction facing the urging force of the leaf spring 38. An evacuation mechanism 23 using a cam mechanism is provided between the dish lift body 27 and the dish support 29. That is, the movable cam 24 functioning as a driving joint is provided on the dish lift body 27, and the fixed cam 39 functioning as a driven joint is formed on the dish support 29. The movable cam 24 has a distal end projecting into a water surface that interferes with a fixed cam 39 formed on the dish support 29, and pivots upward from the horizontal position as shown in FIG. Is supported so that it can return freely, but is not allowed to pivot downward. This is due to the stopper mechanism 40. As a result, the movable cam 24 provided on the dish lift body 27 interferes with the fixed cam 39 formed on the dish support body 29 as the dish lift body 27 moves up and down, whereby the pair of dish supports 29 separate from each other. Rotate in the direction of

For a more accurate understanding of the second dish transport mechanism 15 and the dish stacking mechanism 16, their operation is illustrated in FIG.
Next, description will be made based on (a) to (d) and FIGS. 8 (a) to (d). FIG. 7 is a front view showing a transfer operation of the plate 3 by the second plate transfer mechanism 15. As shown in FIG.
When the plate 3a is positioned at the plate information reading position B and the bar code BC is read by the bar code reader 14, the second motor 33 is activated and its driving force is transmitted to the plate cam 35 via the second gear train 34. Is transmitted to As a result, the plate cam 35 is rotated, and the prime mover 36 is displaced, and the dish lift body 27 is raised, so that the dish 3a located at the dish information reading position B is supported by the dish lift claws 26 of the dish lift body 27. And lifted (FIG. 7 (b)). When the plate 3a further rises, the plate 3b already supported by the plate support claws 28 of the plate support 29 is placed on the upper surface of the plate 3a (FIG. 7C). When the dish lift body 27 further rises, the movable cam 24 attached to the dish lift pawl 26 interferes with the fixed cam 39 formed on the dish support 29, and a pair of movable cams 24 oppose the urging force of the leaf spring 38. The dish support 29 is opened (FIG. 7D).

FIG. 8 is a front view showing the operation of stacking the dishes 3 by the dish stacking mechanism 16. As shown in FIG. 8A, the movable cam 24 of the dish lift claw 26 interferes with the fixed cam 39 of the dish support 29, and the pair of dish supports 29 is opened (FIG. 7D). ), Dish lift claw 2
The dish 3a can be raised by the dish lift body 27 without causing the upper portion of the dish 3a supported by the plate 6 to interfere with the dish support 29. That is, the plate 3 supported by the plate lift pawl 26
The dish support 29 can be retracted by the retreat mechanism 23 at a timing immediately before the “a” interferes with the dish support 29. Then, when the dish lift body 27 further rises, the movable cam 24 comes off from the fixed cam 39 and the action of the cam stops, so that the dish support 29 urged by the leaf spring 38 returns to the original position (FIG. 8). (B)). Thereby, the dish lift claw 2
The plate support 29 returns to its original position after the plate 3 conveyed by the rise of the plate 6 passes through the plate support claws 28.
Here, the leaf spring 38 functions as a return mechanism. FIG.
(B) is a state in which the dish support 29 is raised to the maximum.
From this state, the plate cam 3 driven by the second motor 33
When the rotation of 5 continues, the plate support 29 starts to descend, and the movable cam 24 is caught by the fixed cam 39 and rotates upward (FIG. 8C). As a result, the plate lift 29 is passed through the plate lift 27 without reopening the plate support 29,
7 can be returned to the original position (FIG. 8).
(D)). In this state, the plate 3a, which has been raised by the plate lift claw 26, is supported by the plate support claw 28 in a state where it is located below the plate 3b already supported by the plate support claw 28. And the dishes 3 are stacked.

FIG. 9 is a perspective view showing the dish removal basket 11, and FIG. 10 is a perspective view of the dish support structure 41 in the dish removal basket 11. The dish take-out basket 11 is basically based on a basket frame 43 mainly composed of four pillars 42 surrounding the periphery of the dish 3, and is provided with a frame body 44 having a shape suitable for grasping by a human at an upper portion and a dish support structure 41 at a lower portion. It is a thing. The dish support structure 41 has a structure in which dish holding claws 45 supporting four lower surfaces of the lowermost dish 3 stacked on the dish support portion 28 are connected by a pantograph structure 46, and an operation plate 47 is connected to the pantograph structure 46. is there. That is, the pantograph structure 46 includes a short link 46a connecting the pair of opposed plate holding claws 45a and the operation plate 47, and a long link 46b connecting the other pair of opposed plate holding claws 45b and the operation plate 47. , And the power transmission direction by the rotation of the operation plate 47 that rotates about the support shaft 48 is reversed between the plate holding claw 45a and the plate holding claw 46b. Therefore, as shown in FIG. 10, when the operation plate 47 is vertical, the space between the plate holding claw 45a and the plate holding claw 46b is maintained at a space capable of holding the lower surface of the plate 3, and the operation plate 47 is In a state where the tray 3 is raised horizontally, the distance between the plate holding claw 45a and the plate holding claw 46b is maintained at a distance that does not interfere with the plate 3.

Therefore, the dish removal basket 11 is in a state where the operation plate 47 is raised to the horizontal position, that is, the dish holding claw 4
The space between the plate 5a and the plate holding claw 46b is widened and inserted and held in the opening on the upper surface of the main body case 8. In this case, the dish take-out basket 11 is disposed at a position where the dish holding claw 45 is slightly lower than the lower surface of the lowermost dish 3 stacked on the dish support portion 28. In such a situation,
The dishes 3 are sequentially stacked on the dish support claws 28 without interfering with the dish holding claws 45 of the dish take-out basket 11. When the operation plate 47 is tilted vertically, the distance between the plate holding claw 45a and the plate holding claw 45b is reduced to a distance capable of holding the lower surface of the plate 3, so that the plate take-out basket 11 is kept as it is.
Is taken out of the main body case 8, all the dishes 3 stacked on the dish support claws 28 are removed from the dish removal basket 1.
It is held at 1 and taken out.

In such a configuration, the operation of the dish stacking apparatus 7 according to the present embodiment has already been described together with the structure thereof, and the operation using the dish stacking apparatus 7 will be described below. First, the customer placed at Counter 2
The plate on which the favorite sushi 4 is placed is taken out of the conveyor 5, and after the sushi 4 is eaten, the plate 3 is placed on the plate placing position A. Then, the plate 3 is transported to the plate information reading position B inside the main body case 8, and the barcode BC attached to the plate 3 is read by the barcode reader 14. Then dish 3
Are transported upward to the dish stacking position C, and are sequentially stacked and supported by the dish support portion 29. When the customer finishes eating the sushi 4, an accounting process based on the data of the barcode BC read by the barcode reader 14 is performed by the PO.
While taking place at S terminal / ECR, dish take-out basket 1
By taking out 1, the dishes 3 are taken out at once.

As described above, if the dish stacking apparatus 7 of the present embodiment is installed in a store provided with a conveyor belt sushi system, the dishes 3 are successively stacked and supported at the dish stacking position C corresponding to the customer. In addition, it is possible to prevent troubles such as eating and not eating at the time of accounting processing. Further, since the information on the dishes 3 is conveyed from the dish mounting position A to the dish information reading position B inside the main body case 8 and is read, the number and type of the dishes 3 can be determined without fraud. In this case, since the information of the plate 3 is a barcode BC, even if the information is given to the plate 3, the unit price of the plate 3 can be reduced. Further, since the dish stacking device 7 of the present embodiment is not structurally related to the rotating dining table 6, it is not necessary to largely change existing facilities. As described above, according to the dish stacking device 7 of the present embodiment, it is possible to fulfill many demands desired in a store having the rotating dining table 6.

In carrying out the operation, a belt conveyor was used.

[0030]

According to the dish stacking device of the present invention, the dishes conveyed to the dish stacking position are sequentially stacked.
The dishes after the customer has eaten can be piled up at a predetermined position corresponding to the customer, so that it is possible to prevent the occurrence of troubles such as not eating during the accounting process in operation. The dish stacking device of the present invention also transports the dish from the dish placement position where the customer places the dish to the dish information reading position and reads the information on the dish, so that the customer can eat the dish after eating. The number and type can be determined without fraud. The dish stacking device of the present invention comprises:
Further, since the plate only needs to be provided with a barcode including the identity information of the plate, the unit price of the plate can be reduced. The dish stacking device of the present invention can be further configured without structurally relating to the rotating dining table, so that a system for counting the number of dishes after a customer has eaten significantly increases existing equipment. It can be realized without change. That is, the dish stacking device of the present invention can fulfill many demands desired in a store provided with a rotating dining table.

According to a second aspect of the present invention, in the dish stacking apparatus of the first aspect, the first dish transport mechanism and the rotating mechanism are mainly constituted by two conveyors having different peripheral speeds, for example, a belt conveyor (claim 3). Since it is formed, the first dish transport mechanism and the rotation mechanism can be realized by one structure, so that the structure can be simplified and the cost of parts can be reduced.

According to a fourth aspect of the present invention, in the dish stacking device according to the first aspect, the dishes located at the dish information reading position can be raised and sequentially stacked at an upper position, so that the customer eats. Later dishes can be piled up in the vicinity of the customer corresponding to the customer, and therefore, in operation, it is possible to more reliably prevent troubles such as not eating during the accounting process. . In addition, since the dishes are sequentially stacked at positions above the dish information reading position, the installation space of the apparatus can be reduced, and in this sense, the apparatus does not prompt the change of existing equipment.

The rotary dining table system according to the present invention is characterized in claim 1.
Since the dish stacking device according to any one of the above items 5 to 5, is used, the existing equipment can be effectively used as a rotary dining table that transports dishes on which food is placed along a counter where a plurality of customers are arranged. .
