Devices for transporting food and drink from the kitchen to the audience seats include a circulation type transport device that circulates food and drink between the kitchen and the audience seats, and a non-circulation type transport device that unilaterally transports food and drink from the kitchen to the audience seats. There is. Such a transport device has a transport path having a width corresponding to the size of the food and drink to be transported. Therefore, when it is desired to transport foods and drinks of various sizes, for example, a transport path having a relatively large width is provided.

However, if a transport device having a transport path having a relatively large width is provided in a store where many small foods and drinks are transported, the space of the transport device is wasted and the limited area in the store cannot be effectively utilized. Further, when there are seats on both sides of the transport path, the transport efficiency is poor unless the food and drink to be transported to the audience seats on one side and the food and drink to be transported to the audience seats on the other side cannot be transported at the same time.

Therefore, as a form of a custom-made food and drink transport device capable of controlling the occupied area and improving the transport efficiency while enabling the transport of food and drink of various sizes, parallel two rows of conveyors are provided, and these operations are performed. As a function of the control device for controlling the conveyor, it is conceivable to prepare a mode for synchronizing the movement of the conveyor and a mode for making the movement of the conveyor asynchronous. In such a form, the conveyors in each row can convey different foods and drinks from each other, or the conveyors in each row can cooperate to convey one food and drink.

By the way, the custom-made food and drink transport device is usually provided with a passage sensor that detects the passage of food and drink in the middle of the transport route. Various forms of the pass sensor can be considered, but relatively inexpensive and highly reliable ones include, for example, an optical sensor using a light receiving / receiving element and a contact whose contacts open and close due to physical contact with an object. A switch can be mentioned. However, since the optical sensor detects the presence or absence of an article based on the state of the detected light, for example, when light receiving and emitting parts are provided on both sides of two parallel rows of conveyors, the article that blocks the detected light may be present. It is difficult to identify which of the two rows of conveyors is on. Further, in the case of a contact switch, it is difficult to contact various types of articles conveyed by the conveyor from the side or below.

Therefore, the present application discloses an order food and drink transport device capable of distinguishing the passage of food and drink across both conveyors and the passage of food and drink on one conveyor in a transport path formed by two rows of conveyors. ..

In order to solve the above problems, the present invention uses a contact switch arranged between two rows of conveyors and an optical component fixed to the contact member of the contact switch as a passage sensor provided in the middle of the transport path. I decided to use the optical sensor that I had.

Specifically, the present invention is a custom-made food and drink transport device, in which a parallel two-row conveyor for transporting food and drink from the kitchen to the audience seat and a passage sensor provided in the middle of a transport path formed by the two-row conveyor. And, it is a device that controls the operation of the two rows of conveyors, and in the first mode selected in the case of food and drink that is placed on both of the two rows of conveyors, the movements of the two rows of conveyors are synchronized and the two rows of conveyors are synchronized. In the second mode, which is selected for food and drink placed on one of the conveyors, a control device that makes the movement of the two rows of conveyors asynchronous is provided, and the passage sensor is arranged between the two rows of conveyors. A contact switch that detects the passage of food and drink placed on both conveyors across two rows of conveyors based on the presence or absence of contact with the movable contact member, a first optical component fixed to the contact member, and two rows. It has an optical sensor that detects the passage of food and drink placed on one of the two rows of conveyors based on the state of detection light exchanged between the second optical components provided on both sides of the conveyor.

With the above-mentioned custom-made food and drink transport device, it is possible to reduce the occupied area and improve the transport efficiency while enabling the transport of food and drink of various sizes. Then, the food and drink placed on both of the two rows of conveyors can be detected by the contact switch, and the passage of the food and drink placed on one of the conveyors can be detected by the optical sensor. Further, although the optical sensor has an optical component arranged between the two rows of conveyors, the optical component is fixed to the movable contact member of the contact switch, so that the optical sensor can be mounted on the two rows of conveyors. When the food and drink on both sides pass through the passage sensor, the optical components of the optical sensor do not obstruct the course.

The first optical component may be a reflector, and the second optical component may be a light receiving / receiving element. If the first optical component is a reflector and the second optical component is a light receiving / receiving element, the movable contact member can be simplified.

Further, the contact member may be a member that moves up and down by contact with food and drink placed on both of the two rows of conveyors. If the contact member is an elevating type, it does not hinder the course when the food and drink placed on both of the two rows of conveyors pass through.

In addition, the two rows of conveyors include a main belt conveyor that forms a transport path from the kitchen side of the restaurant to the audience seats, and a secondary belt conveyor that extends to the kitchen side of the main belt conveyor and extends the transport path. When the transport start operation is performed, the control device operates the sub-belt conveyor and the main belt conveyor of at least one of the two rows of conveyors, and the food and drink is transferred from the sub-belt conveyor to the main belt conveyor. When the passage sensor detects that the transfer has been made, the secondary belt conveyor may be in a stopped state in which food and drink to be conveyed next can be placed before the main belt conveyor is stopped.

The above-mentioned custom-made food and drink transport device is equipped with a sub-belt conveyor in addition to the main belt conveyor that forms a transport path from the kitchen side of the restaurant to the audience seats, and the food and drink is transferred from the sub-belt conveyor to the main belt conveyor. When transferring, the sub-belt conveyor will be stopped before the main belt conveyor stops, so even if food and drink are being transported by the main belt conveyor, the food and drink to be transported next should be placed on the sub-belt conveyor. Can be done. Therefore, the next eating and drinking in the kitchen without wasting time while the belt conveyor carries the food and drink to the audience seats, as in the case where the transport path from the kitchen to the audience seats is formed by one belt conveyor. Since the items can be placed on the conveyor belt, the ordered food and drink can be efficiently transported from the kitchen to the audience seats.

Further, when the transport start operation is performed in the first mode, the control device operates the sub-belt conveyor and the main belt conveyor of the two rows of conveyors, and the food and drink is transferred from the sub-belt conveyor to the main belt conveyor. When is detected by the contact switch, before the main belt conveyor is stopped, the sub-belt conveyor is put into a stopped state in which food and drink to be conveyed next can be placed, and when the transfer start operation is performed in the second mode, 2 When the sub-belt conveyor and the main belt conveyor of one of the conveyors in the row are operated and the optical sensor detects that food and drink have been transferred from the sub-belt conveyor to the main belt conveyor, the main belt conveyor is not stopped. In addition, the sub-belt conveyor may be in a stopped state in which food and drink to be conveyed next can be placed.

With such an ordered food and drink transport device, the movements of each conveyor can be synchronized or asynchronous according to the selected mode, so that even if a conveyor with a large width is not installed, for example, the first When one mode is selected, food and drink can be transported by a plate or tray having a size that does not fit on one conveyor. Further, when the second mode is selected, it is possible to simultaneously convey food and drink to various destinations on each conveyor. Therefore, with such a custom-made food and drink transport device, it is possible to transport food and drink with plates or trays of various sizes, and it is possible to reduce the occupied area and improve the transport efficiency.

Further, a type sensor for detecting the presence or absence of food and drink straddling the sub-belt conveyors of the two rows of conveyors is further provided, and the control device is the first when the type sensor detects the food and drink straddling the sub-belt conveyors. The movement of the two rows of conveyors may be controlled according to the mode, and if the type sensor does not detect food or drink straddling the sub-belt conveyors, the movement of the two rows of conveyors may be controlled according to the second mode. If the ordered food and drink transport device is provided with such a control device, it is possible to automatically select a mode according to the type of food and drink without the operation of mode switching by the kitchen staff.

In the case of the custom-made food and drink transport device, it is possible to distinguish between the passage of food and drink on both conveyors and the passage of food and drink on one conveyor in the transport path formed by the two rows of conveyors.

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, beverages, bowls such as udon, fried chicken, tempura, ramen, and grilled meat.

FIG. 1 is an overall configuration diagram of the ordered food and drink transport device 10 according to the embodiment. The custom-made food and drink transport device 10 is a device for transporting food and drink prepared in response to a customer's order from the kitchen 2 of the restaurant to the tables 3L1, 3L2, 3R1, 3R2, and as shown in FIG. A transport path is formed that passes by the side of each table 3L1, 3L2, 3R1, 3R2 for eating and drinking. The custom-made food and drink transport device 10 includes main belt conveyors 20L and 20R that form a transport path from the kitchen 2 side of the restaurant to the tables 3L1, 3L2, 3R1, 3R2. Further, the custom-made food and drink transport device 10 includes sub-belt conveyors 30L and 30R extending on the kitchen 2 side of the main belt conveyors 20L and 20R and extending the transport path. In the present embodiment, the main belt conveyors 20L and 20R are formed in a linear shape, but by combining a plurality of main belt conveyors 20L and 20R, the main belt conveyors 20L and 20R form a transport path having a corner portion. You may try to do it.

A passage sensor 11 for detecting the passage of food and drink is provided in the middle of the transport path formed by the custom food and drink transport device 10. The passage sensor 11 is provided at the end of the main belt conveyors 20L and 20R on the kitchen 2 side, and can detect that food and drink have transferred from the secondary belt conveyors 30L and 30R to the main belt conveyors 20L and 20R. .. Further, between the sub-belt conveyor 30L and the sub-belt conveyor 30R, a type sensor 12 for detecting the presence or absence of food and drink straddling the sub-belt conveyors 30L and 30R is provided. Further, among the transport paths formed by the custom food and drink transport device 10, an electric motor having a left door 13L and a right door 13R is provided at a boundary between the audience seat 3 where the tables 3L1, 3L2, 3R1, 3R2 are located and the kitchen 2. Gate 13 is provided.

The main belt conveyor 20L and the main belt conveyor 20R are each provided with a drive motor that can control rotation independently of each other. The sub-belt conveyor 30L and the sub-belt conveyor 30R are also provided with drive motors that can control rotation independently of each other. Each drive motor is connected to a control device (not shown), and is controlled based on the operation content input to the operation panel and the signal from each sensor. Hereinafter, the operation of the custom food and drink transport device 10 realized by the control device will be described.

The control device of the custom-made food and drink transfer device 10 operates the sub-belt conveyors 30L and 30R and the main belt conveyors 20L and 20R when the transfer start operation is performed on the operation panel, and the food and drink are transferred from the kitchen 2 to the tables 3L1, 3L2. Convey to 3R1 and 3R2. FIG. 2 is a diagram illustrating the screen display of the operation panel. Further, FIG. 3 is a flow chart of control contents executed by the control device of the ordered food and drink transport device 10.

The control device of the ordered food and drink transport device 10 determines whether or not the transport method switching button 41 is pressed on the operation panel 40 (S101). When the control device makes an affirmative determination in step S101, the control device executes the transfer mode switching process (S102). Specifically, the control device changes the set value of the transport mode stored in its own memory. On the operation panel 40, an operation screen corresponding to the setting state of the transport mode is displayed. For example, when the transport mode is "asynchronous mode", a diagram showing that the conveyor is divided into two columns on the left side and the right side is displayed as shown in FIG. 2 (A), and when the transport mode is "synchronous mode". Is displayed with a diagram of one thick conveyor as shown in FIG. 2 (B). Therefore, when the control device executes the transfer mode switching process in step S102, the display screen of the operation panel 40 is switched.

Further, the control device determines whether or not the selection button 42 of the table is pressed on the operation panel 40 when a negative determination is made in step S101 or the process of step S102 is executed (S103). When the control device makes a negative determination in the process of step S103, the control device omits a series of processes from step S104 to step S110 below, and executes the processes of step S101 and subsequent steps again. When the control device makes an affirmative determination in the process of step S103, the control device determines whether or not the currently selected transport mode is the "synchronous mode" (S104). Specifically, the control device refers to the transfer mode setting value stored in its own memory.

When the control device makes an affirmative determination in the process of step S104, it starts all the conveyors, that is, the main belt conveyors 20L and 20R and the sub belt conveyors 30L and 30R (S105). Further, when a negative determination is made in the process of step S104, the control device starts the selected table-side conveyor (S106). For example, when the selection button 42 corresponding to the table 3L1 or the table 3L2 is pressed while the "asynchronous mode" is selected, the control device sets the main belt conveyor 20L and the sub belt conveyor 30L in the process of step S106. to start. Further, for example, when the selection button 42 corresponding to the table 3R1 or the table 3R2 is pressed while the "asynchronous mode" is selected, the control device performs the main belt conveyor 20R and the sub belt conveyor 20R in the process of step S106. Start 30R.

The control device may change the speeds of the main belt conveyors 20L and 20R and the sub belt conveyors 30L and 30R according to the selected transfer mode. The control device is, for example, in the "synchronous mode" selected when transporting a relatively large transported object straddling two parallel conveyors, the "asynchronous mode" selected when transporting a relatively small transported object. The speed of the conveyor may be slower than that.

After executing the process of step S105 or step S106, the control device determines whether or not the food or drink on the started sub-belt conveyors 30L, 30R is on the main belt conveyors 20L, 20R (S107). The control device detects with the passage sensor 11 that the food and drink on the started sub-belt conveyors 30L and 30R has transferred to the main belt conveyors 20L and 20R. When the control device makes an affirmative determination in the process of step S107, the control device stops the sub-belt conveyors 30L and 30R (S108). If the sub-belt conveyors 30L and 30R are stopped, the food and drink to be transported next can be placed on the sub-belt conveyors 30L and 30R even if the food and drink are being transported by the main belt conveyors 20L and 20R.

After executing the process of step S108, the control device determines whether or not the food or drink on the main belt conveyors 20L, 20R has arrived at the destination table 3L1,3L2,3R1,3R2 (S109). The control device may determine whether or not the food or drink has arrived, for example, based on the detection result of the sensor installed near the table 3L1, 3L2, 3R1, 3R2 of the transport destination, or the control device may determine whether or not the food or drink has arrived. The determination may be made based on the elapsed time from the start of transportation set in advance for each position of the tables 3L1, 3L2, 3R1, 3R2. When the control device makes an affirmative determination in the process of step S109, the control device stops the main belt conveyors 20L and 20R (S110).

In the above description from step S107 to step S110, the code "20L, 20R" or the code "30L, 30R" was added to the wording of "conveyor", but it was stopped in steps S108 and 110. Conveyors are one or both of the symbols "20L, 20R" and one or both of the symbols "30L, 30R" according to the selection button 42 and the selected transfer mode. .. The same applies to the transfer destination table, and any one of the tables 3L1, 3L2, 3R1, and 3R2 is the transfer destination table.

FIG. 4 is a diagram showing a transport state of food and drink. For example, when it is desired to transport food and drink placed on a small food and drink 1S that can be carried by any one of the main belt conveyors 20L and 20R, the staff in the kitchen 2 selects "asynchronous mode" on the operation panel 40. Alternatively, after confirming that the "asynchronous mode" is selected, the food and drink 1S is placed on the sub-belt conveyor 30L (or the sub-belt conveyor 30R) and the selection button 42 is pressed, as shown in FIG. 4 (A). As described above, the food and drink 1S on which the food and drink is placed is placed on the sub-belt conveyor 30L (or the sub-belt conveyor 30R) and the main belt conveyor 20L (or the main belt conveyor 20R), and is one of the tables 3L1, 3L2, 3R1, 3R2. Will be transported to. Further, for example, when it is desired to transport food and drink placed on food and drink 1L having a size straddling both the main belt conveyors 20L and 20R, the staff in the kitchen 2 selects "synchronization mode" on the operation panel 40 or "synchronizes". After confirming that "mode" is selected, 1L of food and drink is placed on the sub-belt conveyors 30L and 30R, and when the selection button 42 is pressed, food and drink on which food and drink are placed, as shown in FIG. 4B. The object 1L is placed on the sub-belt conveyors 30L and 30R and the main belt conveyors 20L and 20R, and is conveyed to any of the tables 3L1, 3L2, 3R1, 3R2.

As described above, the custom-made food and drink transport device 10 of the above embodiment can synchronize the main belt conveyor 20L and the main belt conveyor 20R in parallel, or can operate each of them asynchronously and independently. Therefore, for example, when the food and drink 1S, which is a relatively small food, is transported, the main belt conveyor 20L and the main belt conveyor 20R are operated asynchronously and independently from each other to eat and drink to any of the tables 3L1 and 3L2. The transportation of goods and the transportation of foods and drinks to any of the tables 3R1 and 3R2 can be performed at the same time. Further, for example, when transporting 1 L of food and drink, which is a relatively large transported object, the main belt conveyor 20L and the main belt conveyor 20R are operated at the same time so that the movements of the main belt conveyor 20L and the main belt conveyor 20R are synchronized with each other. It is also possible to transport 1 L of food and drink having a size that cannot be conveyed by only one of the conveyors.

The custom-made food and drink transport device 10 of the above embodiment can transport 1 L of food and drink larger than the width of the single conveyor even if it does not have a conveyor having a width on which 1 L of food and drink can be placed. It is possible to reduce the area occupied by the transport device in a limited store, and when transporting a relatively small food or drink 1S, two rows of conveyors can be used independently and simultaneously, so the transport efficiency is good. ..

In the custom-made food and drink transport device 10 of the above embodiment, one transport path is composed of two conveyors, a main belt conveyor 20L (20R) and a sub-belt conveyor 30L (30R). Each may be composed of one conveyor, or may be composed of three or more series conveyors.

Further, in the ordered food / drink transport device 10 of the above embodiment, the transport mode is switched by the switching button 41, but the transport mode is automatically switched based on the detection state of the type sensor 12. Alternatively, the type sensor 12 and the switching button 41 may be used in combination to add a function to prevent erroneous operation by the operator.

FIG. 5 is a diagram showing a passage sensor 11 and a type sensor 12. Further, FIG. 6 is a diagram showing the positional relationship between the passage sensor 11 and the main belt conveyors 20L and 20R. The passage sensor 11 has a contact switch 11A and an optical sensor 11B. Hereinafter, the passage sensor 11 and the type sensor 12 will be described in detail.

The contact switch 11A is a contact type switch that opens and closes when it comes into contact with the contact member 11A1. The contact member 11A1 is arranged between the main belt conveyor 20L and the main belt conveyor 20R, and protrudes above the transport surface of the main belt conveyors 20L and 20R. The contact member 11A1 is urged upward by an elastic body such as a spring, and is lowered when a force pushing downward is applied. The upper surface of the contact member 11A1 is inclined. Therefore, when the sub-belt conveyors 30L and 30R and the main belt conveyors 20L and 20R operate to move the food and drink 1L from the kitchen 2 toward the audience seat 3, and the food and drink 1L comes into contact with the upper surface of the contact member 11A1.
The contact member 11A1 is pushed down by the food and drink 1L. When the contact member 11A1 is pushed down, the contacts of the contact switch 11A come into contact with each other to conduct, and the control device is notified of the passage of food and drink 1L in the passage sensor 11. The contact member 11A1 is provided with a roller at a portion in contact with the food and drink 1L so as not to give sliding resistance to the food and drink 1L. The type sensor 12 is basically the same as the contact switch 11A.

The optical sensor 11B is an optical sensor having a light emitting / receiving element 11B1L, 11B1R and a reflector 11B2L, 11B2R. The light emitting / receiving element 11B1L is arranged on the opposite side of the contact member 11A1 with the main belt conveyor 20L interposed therebetween. Further, the light emitting / receiving element 11B1R is arranged on the opposite side of the contact member 11A1 with the main belt conveyor 20R interposed therebetween. The reflector 11B2L is fixed to the side surface of the contact member 11A1 on the main belt conveyor 20L side. Further, the reflector 11B2R is fixed to the side surface of the contact member 11A1 on the main belt conveyor 20R side. The light receiving / receiving element 11B1L includes a light emitting element that emits detection light (emitted light) toward the reflector 11B2L and a light receiving element that detects the detection light (reflected light) reflected by the reflector 11B2L. Like the light emitting / receiving element 11B1L, the light receiving / receiving element 11B1R also has a light emitting element that emits detection light toward the reflector 11B2R and a light receiving element that detects the detection light reflected by the reflector 11B2R. The type sensor 12 is not provided with one corresponding to the reflectors 11B2L and 11B2R.

In the contact switch 11A as described above, as shown in FIG. 6A, when there is nothing that passes through the passing sensor 11, the detection light emitted from the light emitting element of the light emitting / receiving element 11B1L is a reflector. It is reflected by 11B2L and is incident on the light receiving element of the light receiving / receiving element 11B1L. Further, for example, as shown in FIG. 6B, when the food / drink 1S passes through the passage sensor 11, the detection light emitted from the light emitting element of the light emitting / receiving element 11B1L is blocked by the food / drink 1S. , The detected light does not enter the light receiving element of the light receiving / receiving element 11B1L. In the optical sensor 11B, the passage of food and drink 1S in the passage sensor 11 is detected depending on the presence or absence of the detection light incident on the light emitting / receiving elements 11B1L and 11B1R, and the control device is notified.

Further, since the contact member 11A1 to which the reflectors 11B2L and 11B2R are fixed lowers when the food and drink 1L comes into contact with each other, it obstructs the course of the food and drink 1L passing through the passage sensor 11 as shown in FIG. 6C. do not. Further, since the passage of food and drink 1L in the passage sensor 11 is detected by the contact switch 11A instead of the optical sensor 11B, the reflectors 11B2L and 11B2R are displaced from the optical axes of the light emitting and receiving elements 11B1L and 11B1R as the contact member 11A1 moves. However, there is no problem in detecting the passage of the food and drink 1L by the passage sensor 11.

FIG. 7 is a first diagram showing the positional relationship between the food and drink 1S being transported and the passage sensor 11 and the type sensor 12. For example, when the staff of the kitchen 2 puts the food and drink 1S on the sub-belt conveyor 30L and presses the selection button 42 with the "asynchronous mode" selected, the sub-belt conveyor 30L and the main belt conveyor 20L operate and the left door. 13L opens (see FIGS. 7A and 7B). Then, when the passing sensor 11 detects the passage of the food and drink 1S, the sub-belt conveyor 30L stops and the left door 13L closes at an appropriate timing.

FIG. 8 is a second diagram showing the positional relationship between the food and drink 1L being transported and the passage sensor 11 and the type sensor 12. For example, when the staff of the kitchen 2 places the food and drink 1L on the sub-belt conveyors 30L and 30R and presses the selection button 42 with the "synchronization mode" selected, the sub-belt conveyors 30L and 30R and the main belt conveyors 20L and 20R are pressed. Operates, and the left door 13L and the right door 13R open at the same time (see FIGS. 8A and 8B). Then, when the passing sensor 11 detects the passage of the food and drink 1L, the auxiliary belt conveyors 30L and 30R are stopped, and the left door 13L and the right door 13R are closed at an appropriate timing.

With the custom-made food and drink transport device 10, the occupied area can be suppressed and the transport efficiency can be improved while enabling the transport of food and drink of various sizes. Then, the passage sensor 11 that can identify the passage of both the food and drink 1L and the food and drink 1S can be obtained at a relatively low cost and has excellent reliability without hindering the passage of the food and drink 1L and 1S. It can be composed of a switch 11A and an optical sensor 11B.

In the above embodiment, the case where the passage sensor 11 is provided at the end of the main belt conveyors 20L and 20R on the kitchen 2 side is illustrated, but the custom food and drink transport device 10 is not limited to such a form. The custom-made food and drink transport device 10 may be provided with the passage sensor 11 in the middle of the main belt conveyors 20L and 20R, or at the end on the audience seat 3 side, for example.

Further, in the above embodiment, the emitted light and the reflected light are exchanged between the light receiving / receiving element 11B1L (11B1R) and the reflector 11B2L (11B2R), but either the emitted light or the reflected light is exchanged. You may do so. Further, the positional relationship between the light emitting / receiving element 11B1L (11B1R) and the reflector 11B2L (11B2R) may be reversed.
