It should be understood that the terms "upper", "lower", "front", "back", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In the description of this application, "multiple" and "several" mean two or more, unless otherwise clearly and specifically defined.

[0021] Please also refer to Figure 1 and Figure 2 The automatic baking system provided by the present invention is now described. The automatic baking system includes a storage cabinet 10, an industrial control cabinet 20, and a raw material storage cabinet 30, a proofing cabinet 40, a baking cabinet 50, and a material transfer robot 60 electrically connected to the industrial control cabinet 20. The raw material storage cabinet 30, the proofing cabinet 40, the baking cabinet 50, and the storage cabinet 10 are arranged adjacent to each other in sequence around the material transfer robot 60. The raw material storage cabinet 30, the proofing cabinet 40, and the baking cabinet 50 each have an electrically controlled door 70 controlled by the industrial control cabinet 20. The material transfer robot 60 is used to receive control commands from the industrial control cabinet 20 and transfer materials between the raw material storage cabinet 30, the proofing cabinet 40, the baking cabinet 50, and the storage cabinet 10 in accordance with the control commands.

[0022] It should be noted that, in this embodiment, the raw material storage cabinet 30 can specifically be a refrigerator for refrigerating and storing baking ingredients such as dough. It is only necessary to improve the internal space and refrigerator door of a conventional refrigerator with a front door. Specifically, the interior of the refrigerator is improved to a number of stacked trays to facilitate the material transfer robot 60 to grab the trays and take out the materials. On this basis, it is only necessary to improve the cabinet door to an electrically controlled switch door 70 that is controlled by the industrial control cabinet 20 and can be automatically opened and closed.

[0023] The structure of the proofing cabinet 40 in this embodiment is the same as that of a conventional proofing device. Specifically, it can be an electric heating product designed according to the fermentation principles and requirements of baked foods such as bread. The electric heating tube is used to heat the water in the water pan in the box through the temperature control circuit to create the most suitable fermentation environment with a relative humidity of 80~85% and a temperature of 35℃~40℃. It is only necessary to improve the cabinet door to an electrically controlled switch door 70 that is controlled by the industrial control cabinet 20 and can be automatically opened and closed.

[0024] The structure of the baking cabinet 50 in this embodiment is similar to that of a conventional baking device. Specifically, the cabinet door can be improved on the basis of the conventional baking device to be an electrically controlled switch door 70 that is controlled by the industrial control cabinet 20 and can be automatically opened and closed. On this basis, the baking cabinet 50 can be provided with multiple baking units that work synchronously to improve baking efficiency.

[0025] In this embodiment, the material transfer robot 60 can specifically be an existing six-axis robot, which can rotate and swing along the XYZ axis. The end of the robot is connected to a gripper that is compatible with the above-mentioned pallet, and can use the gripper to accurately grab the pallet at any position within its spatial operating range. Since its spatial operating range is a spherical space, the raw material storage cabinet 30, the proofing cabinet 40, the baking cabinet 50, and the storage cabinet 10 are arranged around the material transfer robot 60 within the spatial operating range, thereby improving the compactness of the overall layout while ensuring that the material transfer robot 60 can smoothly transfer materials.

[0026] It should be noted that in this embodiment, an industrial control cabinet 20 houses an industrial computer (ICC). This refers to an industrial control computer (ICC), a general term for a bus-based tool used to monitor and control production processes, electromechanical equipment, and process equipment. It possesses important computer attributes and characteristics, such as a computer CPU, hard disk, memory, peripherals, and interfaces, an operating system, control networks and protocols, computing power, and a user-friendly human-computer interface. Specifically, in this embodiment, the IPC stores a preset program, specifically a time-based control module for sequentially opening each electrically controlled door 70 and simultaneously controlling the material transfer robot 60 to perform corresponding material transfer actions. The specific control method is conventional in the field of automated control and will not be further described here.

[0027] The working process of the automatic baking system provided in this embodiment is as follows: the staff only needs to place materials into the raw material storage cabinet 30 at a fixed time every day, and then the industrial control cabinet 20 runs according to the preset program. For example, the baking operation is scheduled to start at 4:00 in the morning based on the time control module, the proofing time is 100 minutes (the time set varies according to different product types and specifications), and the baking time is 20 minutes (the time set varies according to different product types and specifications). The electric control switch doors 70 of the raw material storage cabinet 30 and the proofing cabinet 40 are automatically opened at 4:00 in the morning, and the material transfer robot 60 takes out the refrigerated materials from the raw material storage cabinet 30 and puts the materials into the proofing cabinet 40. After the materials are placed, After the dough is ready, the electric switch door 70 is automatically closed to start proofing the materials. When the proofing time reaches the set value, such as one hundred minutes, the electric switch doors 70 of the proofing cabinet 40 and the baking cabinet 50 are automatically opened. Then the material transfer robot 60 takes out the proofed materials from the proofing cabinet 40 and puts them into the baking cabinet 50. Then the electric switch doors 70 are automatically closed to start baking the materials. When the baking time reaches the set value, such as twenty minutes, the materials are processed into mature products such as bread. At this time, the electric switch door 70 of the baking cabinet 50 is automatically opened, and the material transfer robot 60 transfers the mature products from the baking cabinet 50 to the storage rack, thereby completing the automatic baking process from raw dough to mature products.

[0028] Compared with the prior art, the automatic baking system provided in this embodiment arranges the raw material storage cabinet 30, the proofing cabinet 40, the baking cabinet 50, and the storage cabinet 10 around the material transfer robot 60, and controls the automatic opening and closing of the electric-controlled switch doors 70 set toward the material transfer robot 60 of the raw material storage cabinet 30, the proofing cabinet 40, and the baking cabinet 50 through the control cabinet. In this way, the material transfer robot 60 can be used for material transfer and transportation, which not only simplifies the system structure and reduces costs, but also greatly improves the compactness of the system layout, thereby meeting the cost and space requirements for setting up an automatic baking system in a small-area baking store, and is conducive to the development of offline self-service baking stores.

[0029] In some embodiments, see Figure 1 The proofing cabinet 40 includes two proofing units 41 stacked one above the other, each equipped with an electrically controlled door 70. Because different types or specifications of products require different proofing times, such as longer proofing times for large-sized dough compared to smaller-sized dough, the two proofing units 41 employed in this embodiment allow simultaneous proofing of the two types or specifications of dough, thereby improving baking efficiency.

[0030] For further information, see Figure 1The baking cabinet 50 includes a convection oven 51 and a flat oven 52; wherein, the flat oven 52 is used to receive the materials taken out by the material transfer robot 60 from one of the proofing units 41, and the convection oven 51 is used to receive the materials taken out by the material transfer robot 60 from the other proofing unit 41. The convection oven 51 blows out hot air through the fan at the rear, and uses the hot air to bake the food. It can bake multiple layers at the same time and is suitable for baking small-sized products such as cookies, egg tarts, and bread; the flat oven 52 bakes the food from top to bottom through top fire and bottom fire, which helps to better lock in the moisture of the food. It is usually used for single-layer baking of large-sized products. On the basis of using different proofing units 41 for different types or specifications of products to perform proofing operations, the convection oven 51 and the flat oven 52 are correspondingly set in the baking cabinet 50 and matched with one of the proofing units 41, thereby realizing the synchronous processing of different categories of products, thereby improving baking efficiency.

[0031] As a specific embodiment of the above-mentioned open hearth oven 52, please refer to Figure 1 The open-hearth oven 52 includes a plurality of baking units 521 stacked one above the other, each of which is equipped with an electrically controlled door 70. Since conventional open-hearth ovens 52 can only bake a single layer of product, multiple baking units 521 are provided in the open-hearth oven 52, allowing each baking unit 521 to bake a layer of product. This allows for simultaneous processing of multiple trays of product, thereby improving the efficiency of the open-hearth oven 52. Furthermore, the stacked arrangement of the baking units 521 not only improves the compactness of the structural layout but also facilitates the sharing of bottom and top fires between adjacent layers of baking units 521 (the bottom fire of the upper layer also serves as the top fire of the lower layer, i.e., adjacent layers are provided with double-sided heating fire sources), further improving the compactness of the structure and reducing costs.

[0032] It should be noted that if Figure 1 As shown, the raw material storage cabinet 30 , proofing cabinet 40 , and baking cabinet 50 are arranged adjacent to each other in a row, and the storage cabinet 10 is located on the opposite side of the baking cabinet 50 , and a plurality of storage compartments 11 are arranged in an array in the storage cabinet 10 .

[0033] Since bakery stores are usually square spaces, a double-row structure with relative spacing can improve the overall layout regularity, so that the raw material storage cabinet 30, the proofing cabinet 40, and the baking cabinet 50 are arranged adjacent to each other and against the inner wall of the store. The storage cabinet 10 is set on the opposite side of the baking cabinet 50 near the store door, so that customers are away from the processing cabinets and close to the storage cabinet 10, making it convenient for customers to select products.

[0034] For some examples, see Figure 1The storage cabinet 10 is open on the side facing the transfer robot 60, while the side facing away from the transfer robot 60 is enclosed with a transparent panel 12 for viewing the individual storage compartments 11. Since the side of the storage cabinet 10 facing the transfer robot 60 faces away from the customer, it does not require a door and is directly open. This not only saves costs but also makes it easier for the transfer robot 60 to place baked products into the storage cabinet 10. The side of the storage cabinet 10 facing away from the transfer robot 60 faces the customer, so the transparent panel 12 on this side allows customers to easily view the products placed on the individual storage compartments 11, thereby facilitating their selection and improving the customer experience.

[0035] As a specific layout of the above automatic baking system, please see Figure 1 A partition net 80 is installed on the same side of the baking cabinet 50 and the storage cabinet 10, and a self-service bar 90 is installed on the opposite side of the partition net 80. The partition net 80 and the self-service bar 90 cooperate with the cabinets to form an enclosed space, preventing customers from freely entering the space and being accidentally injured by the material transfer robot 60. The partition net 80 takes up little space, ensuring the overall compactness of the system. At the same time, the self-service bar 90 provides customers with a tabletop for placing their belongings, which is conducive to improving the customer experience.

[0036] Specifically, in this embodiment, the self-service bar 90 adopts Figure 1 In the illustrated embodiment, a self-service bar counter 90 is equipped with a point-of-sale screen 21 electrically connected to an industrial control cabinet 20. Specifically, the point-of-sale screen 21 may be a touch screen displaying information such as product categories, prices, and payment codes. By touching a product, the industrial control cabinet 20 receives the corresponding purchase information, which in turn controls the material transfer robot 60 to grab the corresponding product from the storage cabinet 10 and place it on the counter, thus achieving an integrated processing and sales model. It should be noted that the control method and principle for achieving unmanned sales through the electrical connection between the point-of-sale screen 21 and the industrial control cabinet are conventional technologies and will not be elaborated on here.

[0037] Alternatively, see Figure 1 and Figure 2 The above-mentioned electrically controlled switch door 70 includes a door body 71 and a driver 72. The driver 72 is electrically connected to the industrial control cabinet 20 and its output end is connected to the door body 71. The driver 72 is controlled by the industrial control cabinet 20 and is used to drive the door body 71 to open and close. The driver 72 can be a rotary driver 72 such as a motor, with the output end of the rotary driver 72 connected to the rotating shaft of the door body 71, and the rotary driver 72 drives the door body 71 to swing open or close. The driver 72 can also be a telescopic driver 72 such as an electric push rod, with the output end of the telescopic driver 72 hinged to the portion of the door body 71 near its rotating shaft, and the telescopic movement of the telescopic driver 72 drives the door body 71 to swing open or close. This driving method is stable, reliable, and low-cost.

[0038] It should be noted that the aforementioned material transfer robot 60 is equipped with a visual camera 22 electrically connected to the industrial control cabinet 20. The visual camera 22 is used to obtain the open / close status of each door body 71 and provide feedback to the industrial control cabinet 20. Based on the time control module, the industrial control cabinet 20 (specifically, the industrial computer installed therein) sends response action instructions to each electrically controlled door 70 and the material transfer robot 60. To prevent operational errors, the visual camera 22 is installed on the material transfer robot 60 to monitor the open / close status of each electrically controlled door 70 in real time. The material transfer robot 60 performs the corresponding material transfer action only after ensuring that the corresponding electrically controlled door 70 is fully open. This prevents the material transfer robot 60 from colliding with the electrically controlled door 70 during the material transfer action if the door 70 is not properly open, thereby ensuring safe and stable system operation. Of course, it should be understood that using the visual camera 22 connected to the industrial control cabinet 20 to obtain monitoring images and determine the open / close status of the electrically controlled door 70 based on the monitoring images can be achieved using conventional technologies in the field of automation and will not be described in detail here.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
