[0032] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0033] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention.

[0035] Refer to Figure 1 and Figure 7 , the present invention provides a feeding device, including a feeding mechanism, a cartridge grasping mechanism 1 and a cartridge 2. The feeding mechanism includes a cartridge rack 3. The cartridge 2 is placed on the cartridge rack 3. The cartridge 2 is transferred to the feeding station through the feeding mechanism or the cartridge grasping mechanism 1, and the cartridge 2 is grasped by the cartridge grasping mechanism 1 for feeding. The cartridge 2 is provided with several cartridges with different sizes. The cartridge rack 3 is provided with several placement positions for the cartridge 2 at intervals. And in the state where several cartridges 2 are correspondingly placed in several placement positions, the top surfaces of several cartridges 2 or the grasping positions of the cartridge grasping mechanism 1 are the same or similar in height.

[0036] Specifically, the cartridge 2 is used to hold the main ingredients and auxiliary ingredients required for cooking dishes. Since cooking a dish requires various raw materials such as main ingredients and auxiliary ingredients and different amounts, therefore, several cartridges 2 are provided with different sizes to be able to adapt to the corresponding amounts of raw materials. The cartridges 2 in the prior art are designed to be of the same large size, which not only has a high cost and seriously wastes materials, but also is inconvenient for feeding when the large-size cartridge 2 holds a small amount of raw materials, and a large inclination angle or even inversion is required to completely pour the raw materials into the cooking equipment. However, the size of the cartridge 2 of the present invention adapts to the amount of raw materials, greatly reducing the production cost of the cartridge 2 and facilitating feeding.

[0037] A number of material boxes 2 with incomplete identical sizes are placed on a material rack 3. The inner peripheral size of each placement position on the material rack 3 is adapted to the outer peripheral size of the corresponding material box 2, so that the material rack 3 can stably carry the material box 2, facilitating the material box gripping mechanism 1 to stably grip the material box 2 for feeding. Moreover, multiple material boxes 2 are gripped by the material box gripping mechanism 1 at the same height or a similar height, simplifying the gripping operation of the material box gripping mechanism 1 and making the feeding process faster and smoother. Of course, it is preferred that multiple material boxes 2 are gripped by the material box gripping mechanism 1 at the same height, enabling the material box 2 to be gripped accurately, quickly and stably.

[0038] Thus, by setting the material box 2 as a number of boxes with incomplete identical sizes, the feeding device of the present utility model can select a material box 2 with an adapted size for containing according to the usage amounts of raw materials such as main materials and auxiliary materials, not only reducing the difficulty of feeding, but also reducing the production cost of the material box 2. At the same time, by gripping the material box 2 at the same height or a similar height, the difficulty of the gripping operation of the material box 2 is greatly reduced, thus facilitating fast feeding.

[0039] To ensure gripping the material box 2 at the same height or a similar height, the top surfaces of a number of material boxes 2 of the present utility model are at the same height or a similar height, or the gripping positions of the material box gripping mechanism 1 are at the same height or a similar height. It should be noted that the material rack 3 is a plate-like structure and is horizontally placed, and a number of material boxes 2 are placed at intervals on the material rack 3 and are on the same horizontal plane, so that the vertical extension direction of the material box 2 is the height direction of the material box 2.

[0040] Refer to Figure 2 and Figure 3 In the first embodiment, a number of supporting parts 31 are provided on a number of placement positions. The supporting parts 31 protrude from the top surface of the material rack 3 towards the material box 2, and / or the bottom of the material box 2 is provided with supporting feet 21 extending towards the placement position, so that in the state where a number of material boxes 2 are correspondingly placed on a number of placement positions, a number of supporting parts 31 and / or supporting feet 21 make the top surface of the material box 2 or the gripping position of the material box gripping mechanism 1 have the same or a similar height.

[0041] Since the material box 2 has various different sizes, for the material box 2 with the largest size, it can be a conventional box-like structure, and the corresponding supporting part 31 does not protrude or protrudes slightly. For the material box 2 with a smaller size, the corresponding supporting part 31 protrudes, and / or it is provided with supporting feet 21 to be placed on the supporting part 31 through the supporting feet 21. Thus, by adjusting the protruding height of the supporting part 31 and / or the height of the supporting feet 21, different-sized material boxes 2 can be at the same gripping height or a similar gripping height. The protruding height of the supporting part 31 and the height of the supporting feet 21 are determined by the size of the corresponding material box 2 and the gripping height.

[0042] To ensure that the cartridge 2 is stably placed on the support portion 31, the bottom surface of the cartridge 2 is in surface contact with the support portion 31. The support feet 21 are evenly distributed at intervals on the bottom of the cartridge 2, and the support feet 21 are in surface contact with the support portion 31.

[0043] On this basis, a retaining wall 32 extending towards the cartridge 2 is provided at the edge of the support portion 31. When the cartridge 2 is placed on the support portion 31, the retaining wall 32 surrounds the outer peripheral side of the cartridge 2. The retaining wall 32 has a blocking effect and can prevent the cartridge 2 from displacing on the corresponding support portion 31, thereby ensuring that the cartridge 2 is stably placed on the rack 3.

[0044] Refer to Figure 4 、 Figure 5 and Figure 6 In the second embodiment, a plurality of placement positions are a plurality of through holes 33 penetrating the rack 3 in the height direction. The size of the through holes 33 is adapted to the size of the cartridge 2. An outwardly extending flanging 22 is provided at the top edge of the cartridge 2, so that when a plurality of cartridges 2 are correspondingly placed in a plurality of through holes 33, the flanging 22 is placed on the rack 3, and the top surfaces of the plurality of cartridges 2 or the grasping positions of the cartridge grasping mechanism 1 are at the same height or a similar height.

[0045] And / or, a plurality of placement positions are a plurality of through holes 33 penetrating the rack 3 in the height direction. The size of the through holes 33 is adapted to the size of the cartridge 2, or the side wall of the cartridge 2 and the peripheral side of the through hole 33 are correspondingly provided with matching concave and convex structures, so that when a plurality of cartridges 2 are correspondingly placed in a plurality of through holes 33, the cartridge 2 is placed on the rack 3 through the through holes 33, and the top surfaces of the plurality of cartridges 2 or the grasping positions of the cartridge grasping mechanism 1 are at the same height or a similar height.

[0046] That is, when the through holes 33 are provided in the rack 3 as the placement positions, the cartridge 2 is directly clamped on the rack 3, or the cartridge 2 is placed on the rack 3 through the flanging 22 or the concave and convex structure, so as to ensure that the cartridge 2 can be stably placed in suspension. Of course, in the present utility model, the flanging 22 and the concave and convex structure are provided simultaneously to further improve the stability of the placement of the cartridge 2 and prevent the cartridge 2 from swinging in the through hole 33 and affecting grasping.

[0047] Specifically, the provision of the through holes 33 enables the cartridge 2 to be placed in suspension on the rack 3, and the flanging 22 prevents the cartridge 2 from detaching from the rack 3 through the through holes 33. The flanging 22 cooperates with the rack 3 to ensure that the cartridge 2 can be placed on the rack 3. The flanging 22 can be provided at the top axial edge of the cartridge 2 or on the side wall of the cartridge 2, as long as it can ensure that a plurality of cartridges 2 are at the same grasping height or a similar grasping height. Of course, the flanging 22 does not necessarily need to be provided in a circle, and it can be provided locally in the circumferential direction of the cartridge 2, as long as it can ensure that the cartridge 2 is placed on the rack 3 through the flanging 22.

[0048] For the concave-convex structure, most basically, the concave-convex structure is provided on the circumferential inner wall of the through hole 33 and the side wall of the corresponding material box 2. At this time, due to gravity, the top end of the material box 2 is close to the top surface of the material rack 3, which is not convenient for the material box grasping mechanism 1 to grasp the material box 2. Therefore, a boss 35 is provided at the edge of the through hole 33 corresponding to the material rack 3 of the present utility model. The boss 35 extends from the top surface of the material rack 3 towards the material box 2. The flange 22 on the side wall or the top edge of the material box 2 is placed on the boss 35, or the side wall of the material box 2 and the boss 35 are provided with a matching concave-convex structure, so that when a plurality of material boxes 2 are correspondingly placed in a plurality of through holes 33, the distance between the top end of the material box 2 and the top surface of the material rack 3 is set, and the top surfaces of a plurality of material boxes 2 or the grasping positions of the material box grasping mechanism 1 are at the same height or similar heights.

[0049] The boss 35 is vertically arranged to support the bottom of the flange 22 of the material box 2, so that the distance between the top end of the material box 2 and the top surface of the material rack 3 is set, thereby facilitating the material box grasping mechanism 1 to grasp the material box 2. A concave portion 34 is formed by concave-concaving the boss 35, and a matching convex portion 23 is provided on the side wall of the material box 2 corresponding to the concave portion 34, so that the material box 2 is stably placed on the material rack 3 through the cooperation of the convex portion 23 and the concave portion 34. Of course, the boss 35 can also be convexly arranged, and correspondingly, the side wall of the material box 2 is concavely arranged to form a concave-convex structure. <s

[0050] The above is the matching structure of the material box 2 and the material rack 3 to ensure that the material box 2 is stably placed on the material rack 3 and is convenient for the material box grasping mechanism 1 to grasp the material box 2.

[0051] On the basis of the above structure, the material box 2 can be transferred to the feeding station after being grasped by the material box grasping mechanism 1. That is, the material rack 3 is not movable, and the material box grasping mechanism 1 performs horizontal movement and / or vertical movement and / or rotation to the position of the corresponding material box 2. After grasping the material box 2, it performs horizontal movement and / or vertical movement and / or rotation to the feeding station for feeding.

[0052] In the present utility model, referring to Figure 1 , the material box 2 can be transferred to the feeding station through a feeding mechanism. The feeding mechanism further includes a driving device 4. The driving device 4 is used to drive the material rack 3 to move to transport the material box 2 to the feeding station, and the material box grasping mechanism 1 is used to grasp the material box 2 at the feeding station and turn it over for feeding.

[0053] Specifically, the driving device 4 and the material rack 3 are connected through a connecting block 5. The material rack 3 is installed on the connecting block 5. The driving device 4 can drive the connecting block 5 to move horizontally, vertically or rotate to drive the material rack 3 to move synchronously. The driving device 4 is a driving motor, which can drive the connecting block 5 to move horizontally and / or vertically and / or rotate to drive the material rack 3 to move synchronously to the feeding station, and then the material box grasping mechanism 1 grasps the material box 2 for feeding.

[0054] On this basis, the material rack 3 and the connecting block 5 are connected as an integral structure, thereby ensuring the stability of the connection between the material rack 3 and the connecting block 5, thereby facilitating the rapid and stable delivery of the material box 2 to the feeding station.

[0055] Alternatively, the material rack 3 and the connecting block 5 can be detachably connected, for example, by magnetic attraction, snap-on connection, or plug-in connection. Because different dishes require different quantities and amounts of ingredients, such as main and auxiliary ingredients, the number and size of the material boxes 2 used to hold the ingredients vary for different dishes, and the structure of the material rack 3 varies accordingly. The detachable connection between the material rack 3 and the connecting block 5 facilitates replacement of the material rack 3 and material boxes 2 to suit the dish.

[0056] After the driving device 4 drives the material rack 3 to move and transport the material box 2 to the feeding station, the material box grabbing mechanism 1 grabs the material box 2 for feeding. Figure 7 The material box grasping mechanism 1 is a clamping mechanism for clamping the material box 2 for flipping and feeding. The clamping mechanism includes a clamping arm 11 for clamping the material box 2. The relative top edge or relative side wall of the material box 2 is provided with a clamping position 24, and the clamping arm 11 is provided with a clamping portion 12 adapted to the shape of the clamping position 24.

[0057] The clamping arm 11 is driven by an electromagnetic or motor to achieve clamping and releasing operations. The clamping position 24 is located on the side wall or the top edge of the magazine 2. The clamping portion 12 is located on the inner wall of the clamping arm 11 so as to face the clamping position 24. The clamping portion 12 cooperates with the clamping position 24 to ensure that the clamping arm 11 can stably clamp the magazine 2.

[0058] Specifically, the clamping position 24 is provided with a clamping edge extending outward from the top edge of the magazine 2. The clamping portion 12 is provided with a slot adapted to fit the clamping edge, and the clamping edge is secured within the slot. The clamping edge can be a flange 22 provided on the circumferential edge of the magazine 2. When the clamping arm 11 clamps the magazine 2, the flange 22 is secured within the slot, ensuring that the magazine 2 is stably clamped by the clamping arm 11.

[0059] Alternatively, the clamping position 24 and the clamping portion 12 may be connected via a concave-convex structure. Specifically, the clamping position 24 may have a protrusion extending outward from the sidewall of the cartridge 2, and the clamping portion 12 may have a receiving portion adapted to accommodate the protrusion, with the protrusion being located within the receiving portion. Alternatively, the clamping position 24 may have a concave portion extending inward from the sidewall of the cartridge 2, and the clamping portion 12 may have a protrusion adapted to accommodate the concave portion, with the concave portion and the protrusion matching in shape.

[0060] Whether it is the card connection structure between the card edge and the card slot or the concave-convex structure, it is to improve the stability of the clamping arm 11 clamping the material box 2. Of course, in actual application, a plug-in structure can also be set to ensure that the clamping arm 11 stably clamps the material box 2.

[0061] The above is the feeding device of the present invention. On the basis of the above feeding device, the present invention also provides a cooking device, which includes the above feeding device and a cooking pot. The feeding device is used to transport raw materials such as main ingredients and auxiliary ingredients to the cooking pot and feed them, and then cook dishes through the cooking pot.

[0062] Different dishes require different types, quantities and amounts of raw materials such as main ingredients and auxiliary ingredients. When cooking a dish, a material box 2 of appropriate size is selected and a suitable material rack 3 is adapted according to the type, quantity and amount of raw materials required for the dish. Then, the material box 2 is moved to the cooking pot position through the feeding mechanism or the material box grabbing mechanism 1, and the material box 2 is grabbed by the material box grabbing mechanism 1 at the same height or a similar height and then turned over to add the ingredients into the cooking pot, thereby completing the preparation of the dish in the cooking pot.

[0063] By providing a plurality of material boxes 2 of different sizes, the cooking device can select a material box 2 of an appropriate size according to the amount of raw materials such as the main ingredient and auxiliary ingredients, thereby reducing the difficulty of feeding and the production cost of the material box 2. At the same time, by grasping the material box 2 at the same height or a similar height, the difficulty of grasping the material box 2 is greatly reduced, thereby facilitating and quickly feeding, greatly improving the smoothness of the cooking process, and facilitating cooking efficiency.

[0064] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
