[0009] First Embodiment A food and drink conveying apparatus 200 according to a first embodiment, which is an example of the present invention, will be described below with reference to the accompanying drawings. Each aspect described below is assumed to be a store that mainly serves sushi as food and drink, but it may also be a store that serves food and drink other than sushi (rice bowls such as udon, fried chicken, tempura, ramen, yakiniku, etc.).

[0010] FIG. 1 is a schematic diagram of a food and drink conveying device 200 according to a first embodiment of the present invention.

[0011] The food and beverage conveying device 200 is placed in the store's kitchen and is configured as a device that distributes and conveys plates D carrying food and beverages (especially sushi) prepared by the cooking staff in the kitchen to each customer seat, more specifically, to multiple rows of customer seats (rows A to C in Figure 1).

[0012] Specifically, food and drink conveying apparatus 200 includes a first conveying path 10, a second conveying path 20, a third conveying path 30, a fourth conveying path 40, and a recovery conveying path 50.

[0013] The first transport path 10 has a conveyor 11, an RFID (Radio Frequency Identification) reader / writer 12, a branch conveyor 13, a conveyor 14, a grilling device 100, a branch conveyor 15, and a conveyor 16. The first transport path 10 is connected to customer seat row A on the downstream side.

[0014] Conveyor 11 supplies plates D carrying rice S, an example of a food made from grains, sent from an upstream work area or device (not shown) to kitchen K1. In kitchen K1, cooking staff take sushi toppings N, an example of an ingredient, from sushi topping cases 60 and place them on the rice S. Conveyor 11 transports plates D carrying sushi after cooking (attaching the toppings N) in kitchen K1 to branch conveyor 13.

[0015] The conveyor 11 is configured so that it can be switched between driving and stopping by operating a manual switch (not shown) that is operated by a cooking staff member or the like arranged in the kitchen K1.

[0016] Therefore, for example, when a certain number of plates D with rice S on them arrive at kitchen K1 (for example, three), the cooking staff operates a manual switch to stop the conveyor 11, and the multiple plates D to be worked on are placed in kitchen K1 (in front of the cooking staff), and the cooking staff can then attach sushi toppings N according to the order to the rice S on each plate D. The cooking staff can understand the order details by, for example, referring to the display on a display device (not shown) provided near kitchen K1.

[0017] The RFID reader / writer 12 is installed downstream of the conveyor 11. The RFID reader / writer 12 is a device that detects the arrival of a plate D carrying cooked sushi, and writes and / or reads plate information to and from the plate D (more specifically, an RF (Radio Frequency) tag embedded in the plate D).

[0018] In this embodiment, the concept of writing plate information onto plate D includes writing the plate information into an information writing area such as an RF tag embedded in the plate D itself, as well as writing the plate information into an information writing area provided on an accessory (such as a cover that covers the sushi) that is attached to the plate D and transported together with the plate D (sushi). The same applies to the concept of reading plate information from plate D. Plate information includes, for example, the contents of the food or drink (type of sushi), the date and time of production, the destination (seat information), etc.

[0019] The branch conveyor 13 has a movable lever 13a that can be switched between a first position (position shown by a solid line in Figure 1) in which the plate D is guided to the conveyor 14, and a second position (position shown by a dotted line in Figure 1) in which the plate D is guided to the second conveying path 20.

[0020] Branch conveyor 13 switches the position of movable lever 13a based on the plate information of plate D read by RFID reader / writer 12. In the example of Figure 1, plate D is guided to conveyor 14 if the sushi requires toppings, if the sushi requires searing, or if the destination is customer row A.

[0021] Conveyor 14 supplies plates D sent from branch conveyor 13 to kitchen K2. In kitchen K2, cooking staff take toppings T such as green onions, ginger, mayonnaise, etc. from topping case 61 and place them on the sushi toppings N. Conveyor 14 transports plates D with sushi after cooking (topping placement) in kitchen K2 to grilling device 100.

[0022] Like the conveyor 11, the conveyor 14 is configured to be able to switch between driving and stopping by operating a manual switch (not shown) operated by a cooking staff member or the like arranged in the kitchen K2.

[0023] Therefore, for example, when a certain number of plates D carrying sushi (for example, two) arrive at kitchen K2, the cooking staff operates a manual switch to stop the conveyor 14, and the multiple plates D to be worked on are placed in kitchen K2 (in front of the cooking staff), and the cooking staff can then place toppings according to the order on the sushi ingredients N on each plate D. The cooking staff can understand the order details by, for example, referring to the display on a display device (not shown) provided near kitchen K2.

[0024] The grilling device 100 is a device that grills ingredients placed on top of food made from grains. In this embodiment, the grilling device 100 is configured to grill sushi ingredients N placed on rice S. In addition, toppings T may also be grilled.

[0025] The food made from grains is not limited to rice sushi rice S, but may be, for example, rice balls, bread, pie crust, pizza crust, crackers, etc., and the ingredients placed on top of the food made from grains are not limited to sushi toppings N, but may be, for example, cheese, meat, vegetables, eggs, seafood other than sushi toppings, etc. Furthermore, the above-mentioned toppings T can also be considered to be ingredients placed on top of the food made from grains.

[0026] The grilling device 100 transports the plate D carrying the sushi that needs to be grilled to a predetermined grilling position and grills the ingredients (sushi toppings N, toppings T) based on the plate information of the plate D read by the RFID reader / writer 12. The grilling device 100 will be described in detail later.

[0027] The branch conveyor 15 has a movable lever 15a that can be switched between a first position (position shown by a solid line in Figure 1) in which the plate D is guided to the conveyor 16, and a second position (position shown by a dotted line in Figure 1) in which the plate D is guided to the third conveying path 30.

[0028] The branch conveyor 15 switches the position of the movable lever 15a based on the plate information of the plate D read by the RFID reader / writer 12. In the example of FIG. 1, the branch conveyor 15 guides the plate D destined for seat row A to the conveyor 16.

[0029] The conveyor 16 supplies the plates D sent from the branch conveyor 15 toward the seat row A.

[0030] The second transport path 20 has a conveyor 21, a conveyor 22, an RFID reader / writer 23, a branch conveyor 24, and a conveyor 25. The second transport path 20 is connected to seat row B on the downstream side.

[0031] The conveyor 21 supplies the plates D sent from the branch conveyor 13 to the conveyor 22.

[0032] The conveyor 22 supplies the plates D sent from the conveyor 21 to the branch conveyor 24.

[0033] The RFID reader / writer 23 is provided downstream of the conveyor 22. The function of the RFID reader / writer 23 is similar to that of the RFID reader / writer 12.

[0034] The branch conveyor 24 has a movable lever 24a that can be switched between a first position (position shown by a solid line in Figure 1) in which the plate D is guided downstream and a second position (position shown by a dotted line in Figure 1) in which the plate D is guided to the recovery conveying path 50, and a movable lever 24b that can be switched between a first position (position shown by a solid line in Figure 1) in which the plate D is guided to the conveyor 25 and a second position (position shown by a dotted line in Figure 1) in which the plate D is guided to the fourth conveying path 40.

[0035] Branch conveyor 24 switches the positions of movable lever 24a and movable lever 24b based on the plate information of plate D read by RFID reader / writer 23. In the example of Fig. 1, plate D etc. for which an error occurred in reading the plate information is guided to recovery conveying path 50, plate D destined for customer seat row B is guided to conveyor 25, and plate D destined for customer seat row C is guided to fourth conveying path 40.

[0036] The conveyor 25 supplies the plates D sent from the branch conveyor 24 toward the seat row B.

[0037] The fourth transport path 40 has a conveyor 41 and a conveyor 42. The fourth transport path 40 is connected to the seat row C on the downstream side.

[0038] The conveyor 41 supplies the plates D sent from the branch conveyor 24 to the conveyor 42.

[0039] The conveyor 42 supplies the plates D sent from the conveyor 41 toward the seating row C.

[0040] The recovery transport path 50 has a conveyor 51. The recovery transport path 50 recovers plates D and the like for which an error has occurred in reading the plate information.

[0041] The third transport path 30 has a conveyor 31, a conveyor 32, and a conveyor 33. The third transport path 30 is connected to the second transport path 20 on the downstream side.

[0042] The conveyor 31 supplies the plates D sent from the branch conveyor 15 to the conveyor 32.

[0043] The conveyor 32 supplies the plates D sent from the conveyor 31 to the conveyor 33.

[0044] The conveyor 33 supplies the plates D sent from the conveyor 32 to the conveyor 22.

[0045] Next, the roasting device 100 will be described.

[0046] Fig. 2 is a schematic diagram of the grilling device 100. Fig. 3 is a diagram for explaining the first grilling section 110. Fig. 4 is a diagram for explaining the second grilling section 120. Fig. 5 is a diagram for explaining the layout of the first grilling section 110 and the second grilling section 120.

[0047] As shown in FIG. 2, the grilling device 100 has a housing 190, two first grilling sections 110, two second grilling sections 120, and a conveyor 130 as an example of a transport section.

[0048] Although not shown, a blower, an electrical unit, etc. are housed in the lower part of the housing 190, and piping, various valves, etc. are housed in the upper part of the housing 190.

[0049] In this embodiment, two second roasting sections 120 and two first roasting sections 110 are provided in this order from the upstream side in the conveying direction of the conveyor .

[0050] The conveyor 130 transports the plate D to a predetermined grilling position based on the plate information of the plate D sent from the conveyor 14.

[0051] Specifically, when the plate information (type of sushi) indicates sushi that requires searing and is a one-piece sushi dish, the predetermined searing positions are searing position P3 and searing position P4. Searing position P3 corresponds to the first searing section 110 located upstream of the two first searing sections 110, and searing position P4 corresponds to the first searing section 110 located downstream of the two first searing sections 110.

[0052] In this embodiment, after the first searing is performed at searing position P3, plate D is transported to searing position P4, where the second searing is performed. The reason why two first searing sections 110 are provided is because searing ingredients in two stages can increase the searing processing speed rather than searing ingredients all at once. Note that searing device 100 may also be configured with one first searing section 110.

[0053] Furthermore, if the plate information (type of sushi) indicates sushi that requires searing and that is served in two pieces, the predetermined searing positions are searing position P1 and searing position P2. Searing position P1 is a position corresponding to the second searing section 120 located upstream of the two second searing sections 120, and searing position P2 is a position corresponding to the second searing section 120 located downstream of the two second searing sections 120.

[0054] In this embodiment, the first searing is performed at searing position P1, and the second searing is performed at searing position P2. The reason why two second searing units 120 are provided is because searing the ingredients in two stages can increase the searing processing speed rather than searing the ingredients all at once. Note that the searing device 100 may also be configured to have one second searing unit 120.

[0055] In this way, the first grilling unit 110 is configured to grill the sushi topping (first ingredient) N for one piece of sushi, and the second grilling unit 120 is configured to grill the sushi topping (second ingredient) N for two pieces of sushi. In other words, the first grilling unit 110 is configured to accommodate a first ingredient having a first width, and the second grilling unit 120 is configured to accommodate a second ingredient having a second width that is wider than the first width.

[0056] As shown in FIG. 3, the first grilling section 110 has a first flame blowing section 111 that blows a first flame diagonally downward, and a second flame blowing section 112 that blows a second flame that intersects with the first flame diagonally downward.

[0057] The first flame blowing section 111 and the second flame blowing section 112 are arranged side by side in the transport direction of the conveyor 130. In this embodiment, the first flame blowing section 111 and the second flame blowing section 112 are arranged symmetrically across a reference plane B1 that is perpendicular to the transport direction of the conveyor 130.

[0058] However, first flame blowing part 111 and second flame blowing part 112 may be arranged asymmetrically across reference plane B1, and for example, they may differ in height, width, angle, flame strength, etc. Furthermore, first flame blowing part 111 and second flame blowing part 112 may be set so that their respective positions are immovable (unadjustable), or may be set so that their respective positions are movable (adjustable).

[0059] The grilling positions P3 and P4 are located in the area where the first flame and the second flame meet. That is, the conveyor 130 is configured to transport the sushi ingredients N placed on the rice S to the area where the first flame and the second flame meet.

[0060] As shown in FIG. 4, the second grilling section 120 has a first flame blowing section 121 that blows out a first flame diagonally downward, and a second flame blowing section 122 that blows out a second flame that intersects with the first flame diagonally downward.

[0061] The first flame blowing section 121 and the second flame blowing section 122 are arranged side by side in the transport direction of the conveyor 130. In this embodiment, the first flame blowing section 121 and the second flame blowing section 122 are arranged symmetrically across a reference plane B2 that is perpendicular to the transport direction of the conveyor 130.

[0062] However, first flame blowing part 121 and second flame blowing part 122 may be arranged asymmetrically across reference plane B2, and for example, they may differ in height, width, angle, flame strength, etc. Furthermore, first flame blowing part 121 and second flame blowing part 122 may be set so that their respective positions are immovable (unadjustable), or may be set so that their respective positions are movable (adjustable).

[0063] The grilling positions P1 and P2 are located in the area where the first flame and the second flame meet. That is, the conveyor 130 is configured to transport the sushi ingredients N placed on the rice S to the area where the first flame and the second flame meet.

[0064] As described above, the first grilling section 110 is configured to correspond to a first food ingredient (such as sushi material N for one roll) having a first width, and the second grilling section 120 is configured to correspond to a second food ingredient (such as sushi material N for two rolls) having a second width wider than the first width. Note that the width of the sushi material N is the length in the short side direction of the sushi.

[0065] Specifically, as shown in FIG. 5, the positions of the first flame ejection section 111 and the second flame ejection section 112 of the first grilling section 110 used when grilling the first food ingredient are spaced closer in the width direction of the food ingredient (L1 < L2) compared to the positions of the first flame ejection section 121 and the second flame ejection section 122 of the second grilling section 120 used when grilling the second food ingredient, and are farther away from the grilled surface in the direction orthogonal to the width direction of the food ingredient and away from the grilled surface (H1 > H2).

[0066] Thereby, as shown in FIG. 3, the first grilling section 110 can form a region where the first flame and the second flame are combined according to the sushi material N for one roll, so that it is easy to match the range of the flame at a temperature suitable for grilling to the sushi material N for one roll. Therefore, the surface of the sushi material N can be grilled without unnecessarily burning the shari S of the sushi provided in one roll.

[0067] Also, as shown in FIG. 4, the second grilling section 120 can form a region where the first flame and the second flame are combined according to the sushi material N for two rolls, so that it is easy to match the range of the flame at a temperature suitable for grilling to the sushi material N for two rolls. Therefore, the surface of the sushi material N can be grilled without unnecessarily burning the shari S of the sushi provided in two rolls.

[0068] Therefore, according to the grilling device 100 of the present embodiment, even if the widths of the food ingredients (such as sushi material N) are different, different-width food ingredients can be grilled in the same manner as compared to the case of grilling with the ejection sections set at the same position.

[0069] In addition, in this embodiment, the conveyor 130 transports a first ingredient having a first width (such as sushi topping N for one piece of sushi) and a second ingredient having a second width wider than the first width (such as sushi topping N for two pieces of sushi), and the grilling positions (P3, P4) for grilling the first ingredient and the grilling positions (P1, P2) for grilling the second ingredient are located at different positions on the conveyor 130.

[0070] This allows the positions of first flame blowing portions 111, 121 and second flame blowing portions 112, 122 to be fixed and set. Note that it is possible to adjust the positions of first flame blowing portions 111, 121 and second flame blowing portions 112, 122 depending on the ingredient being grilled (such as sushi topping N). For example, even when two pieces of sushi are served, it is possible to adjust the positions of first flame blowing portion 121 and second flame blowing portion 122 depending on whether tuna is being grilled or conger eel is being grilled. Even if such adjustments are possible, it can be said that the positions of first flame blowing portion 121 and second flame blowing portion 122 are fixed and set.

[0071] In the grilling device 100, the ingredients (such as sushi toppings N) transported by the conveyor 130 are arranged so that their width (the short side of the sushi) coincides with the transport direction. In other words, the ingredients transported to the area where the first flame and the second flame meet face a specific direction.

[0072] In this embodiment, as shown in Figure 1, the orientation of the rice S placed on plates D sent from a work area or device to conveyor 11 is aligned from the beginning, so that the orientation of the sushi ingredients N also faces a predetermined direction. However, food and drink conveying device 200 may also be provided with a device upstream of grilling device 100 that aligns the orientation of ingredients (such as sushi ingredients N) in a predetermined direction.

[0073] This allows the food to be seared in the same way compared to when it is facing in a different direction.

[0074] Furthermore, the grilling device 100 of this embodiment is configured to transport ingredients (such as sushi toppings N) to the area where the first flame and the second flame meet, and then grill the ingredients by blowing out the first flame and the second flame from the first flame blowing sections 111, 121 and the second flame blowing sections 112, 122.

[0075] This reduces the time that the flames hit the food (rice S, etc.) and the plate D compared to when the flames are blown out first.

[0076] Furthermore, in this embodiment, the food material (such as sushi topping N) is grilled by the first flame and the second flame while remaining stationary in the area where the first flame and the second flame meet.

[0077] This reduces searing spots compared to when the food material (such as sushi topping N) is moving.

[0078] As described above, the grilling device 100 of this embodiment is provided with a plurality of grilling positions (P3, P4) for grilling the first food material and a plurality of grilling positions (P1, P2) for grilling the second food material. The food material is grilled in multiple batches (two batches in this embodiment).

[0079] This allows the surface of the food to be seared to the same degree efficiently (with high productivity) compared to when the food is exposed to the flame once in one place.

[0080] In this embodiment, the grilling positions P1, P2, P3, and P4 are arranged in order from the upstream side in the conveying direction of the conveyor 130. However, the arrangement of the grilling positions (P1 to P4) may be interchanged as appropriate. That is, the grilling positions (P3, P4) for grilling the first food ingredient may be arranged upstream of the grilling positions (P1, P2) for grilling the second food ingredient, or the grilling positions (P3, P4) for grilling the first food ingredient and the grilling positions (P1, P2) for grilling the second food ingredient may be arranged alternately. Furthermore, in the grilling device 100, the number of grilling positions for grilling the first food ingredient and the number of grilling positions for grilling the second food ingredient can be changed as appropriate, and it is sufficient if at least one of either one is provided.

[0081] Next, a first broiling section 140 according to a modified example will be described. Figure 6 is a diagram for explaining the first broiling section 140 according to a modified example.

[0082] As shown in FIG. 6, the first grilling section 140 has a first flame blowing section 141 that blows a first flame diagonally downward, and a second flame blowing section 142 that blows a second flame that intersects with the first flame diagonally downward.

[0083] Furthermore, first flame blowing section 141 has a shielding plate 141a that limits the range of the first flame, and second flame blowing section 142 has a shielding plate 142a that limits the range of the second flame.

[0084] The first flame blowing section 141 and the second flame blowing section 142 are arranged side by side in the transport direction of the conveyor 130. The first flame blowing section 141 and the second flame blowing section 142 are arranged symmetrically across a reference plane B3 that is perpendicular to the transport direction of the conveyor 130.

[0085] However, first flame blowing part 141 and second flame blowing part 142 may be arranged asymmetrically across reference plane B3, and for example, their heights, widths, angles, flame strength, etc. Furthermore, first flame blowing part 141 and second flame blowing part 142 may be set so that their respective positions are immovable (unadjustable), or may be set so that their respective positions are movable (adjustable).

[0086] According to this, the range of the flame that hits the food material can be adjusted to any range by using the shielding plates 141a and 142a. In the example of Fig. 6, the range of the flame is limited to fit the sushi topping N of one piece of sushi.

[0087] Furthermore, the positions of the first flame blowing section 141 and the second flame blowing section 142 of the first roasting section 140 may be the same as those of the second roasting section 120. In this case, the first roasting section 140 can be easily realized by modifying the second roasting section 120 to provide shielding plates 141a and 142a.

[0088] The main functions and effects of the grilling device 100 will be summarized below.

[0089] A grilling device 100 for grilling ingredients (such as sushi toppings N) placed on food (such as rice S) made of grains includes first flame blowing sections 111, 121 that blow out a first flame diagonally downward, second flame blowing sections 112, 122 that blow out a second flame that intersects with the first flame diagonally downward, and a conveyor 130 that transports the ingredients placed on the food made of grains to an area where the first flame and the second flame meet.

[0090] This allows the food to be seared in the area where the first flame and the second flame meet, making it easy to match the range of flame temperatures suitable for searing to the food. Therefore, when searing food placed on top of a grain food, the surface of the food can be seared without unnecessarily burning the food.

[0091] Conveyor 130 transports a first ingredient (such as sushi topping N for one piece of sushi) having a first width and a second ingredient (such as sushi topping N for two pieces of sushi) having a second width wider than the first width, and the positions of first flame outlet 111 and second flame outlet 112 when searing the first ingredient are closer together in the width direction of the ingredient and are farther away from the searing surface in a direction perpendicular to the width direction of the ingredient and away from the searing surface of the ingredient than the positions of first flame outlet 121 and second flame outlet 122 when searing the second ingredient.

[0092] This allows ingredients (such as sushi toppings N) of different widths to be seared in the same way, compared to searing ingredients at outlets set at the same position.

[0093] The grilling positions (P3, P4) for grilling the first food material and the grilling positions (P1, P2) for grilling the second food material are located at different positions on the conveyor 130.

[0094] According to this, the positions of the first flame blowing parts 111, 121 and the second flame blowing parts 112, 122 can be fixed and set.

[0095] The food material (such as sushi topping N) conveyed to the area where the first flame and the second flame join faces a predetermined direction.

[0096] This allows the food to be seared in the same way compared to when it is facing in a different direction.

[0097] After transporting ingredients (such as sushi toppings N) to an area where the first flame and the second flame meet, the grilling device 100 blows out the first flame and the second flame from the first flame blowing sections 111, 121 and the second flame blowing sections 112, 122.

[0098] This reduces the time that the flames hit the food (rice S, etc.) and the plate D compared to when the flames are blown out first.

[0099] The food material (such as sushi topping N) is grilled by the first flame and the second flame while remaining stationary in the area where the first flame and the second flame meet.

[0100] This reduces searing spots compared to when the food material (such as sushi topping N) is moving.

[0101] The grilling device 100 has multiple grilling positions (P3, P4) for grilling the first ingredient (such as sushi topping N for one piece of sushi) and multiple grilling positions (P1, P2) for grilling the second ingredient (such as sushi topping N for two pieces of sushi), and the ingredients are grilled in multiple batches.

[0102] This allows the surface of the food to be seared to the same degree efficiently (with high productivity) compared to when the food is exposed to the flame once in one place.
