Description

Technical Field

[0001] The present invention relates to a device for use in food vending situations. More particularly, the present invention relates to an automatic food vending machine for use in meal situations. Background Art

[0002] The traditional catering industry currently faces challenges such as high costs, relatively saturated distribution channels, and limited market growth potential. Rising store rental and labor costs are causing traditional catering companies' profit margins to decline. Meanwhile, while the rapid growth of online food delivery has effectively helped restaurant brands expand their reach, it has also brought significant platform fees.

[0003] Under such circumstances, the current popular meal sales model has a huge opportunity for transformation. Automatic meal vending / ordering machines have been a hot and promising development direction in the past two years. They are in line with the current trend of industrial mechanization and unmanned operations. Therefore, automatic lunch box vending machines have appeared on the market to meet people's needs. However, their disadvantages are that they sell ready-made lunch boxes, so they cannot be sold in real time according to needs. Moreover, the dishes they sell are relatively single, and it is impossible to sell porridge, braised dishes, and stir-fried dishes on a single vending machine. Moreover, they are basically only practical for sales occasions with relatively concentrated white-collar workers and cannot meet the automatic sales needs of large cafeterias at different time periods.

[0110] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0111] It should be understood that terms such as “having,” “including,” and “comprising” used herein do not prescribe the existence or addition of one or more other elements or combinations thereof.

[0112] Figure 1-7 The present invention shows an implementation of an automatic vegetable vending machine, which includes:

[0113] A vegetable storage bucket group 1 for storing vegetables and arranged in a herringbone shape is provided on the bucket, which is equipped with a power component for providing power to the stirring component and the blocking component inside the vegetable storage bucket, so that when the blocking component is opened, the stirring component stirs one or two circles, rotating and pushing the contents of the bucket out of the vegetable or rice outlet;

[0114] The vegetable storage barrel group includes a porridge barrel 1100, a cooking barrel 1200, and a cooking barrel 1300 for respectively storing porridge, cooking, and stir-frying to be sold.

[0115] The porridge bucket, cooking bucket and stir-fry bucket all include:

[0116] The barrels 1110, 1210, 1310 are used to hold porridge or dishes to be sold, and the bottoms thereof are provided with dish or rice outlets 1111, 1211, 1311, which are used to connect the rice or dishes to an external structure or a rice plate or bowl through the dish or rice outlets;

[0117] The covers 1120, 1220, and 1320 cooperate with the barrel body to seal the interior of the barrel body, thereby sealing the porridge contained therein to prevent contamination from the outside, and also provide a mounting portion for other components;

[0118] A stirring assembly 1130, 1230, 1330 is provided inside the barrel body, and one end of the stirring assembly passes through the cover body so as to be in driving connection with the first power output shaft of the power assembly, so as to make the contents of the barrel fall into the dish or rice outlet along with the rotation, thereby adjusting the thickness of the porridge when it is discharged. The stirring assembly is used to rotate the stirring assembly through the rotation output of a power mechanism such as a motor, so that the porridge or the dish can rotate together, thereby making the porridge or the dish smoothly pass through the rice outlet and fall into other equipment or a dish plate, and at the same time making the thickness of the porridge adjustable and the completeness of the dish controllable;

[0119] At a position inside the barrel corresponding to the dish or rice outlet, a blocking assembly 1140, 1240, 1340 is provided, which penetrates the cover and is connected to the second power output shaft of the power assembly to switch the working state of the dish or rice outlet. The blocking assembly 1140, 1240, 1340 is used to continuously switch the working state of the dish or rice outlet through the reciprocating motion of the pneumatic assembly, so as to achieve the effect of releasing porridge or vegetables as needed. The vegetable storage barrel adopting this scheme works in such a way that when the blocking assembly is lifted by the action of the pneumatic mechanism, the stirring assembly rotates one or two circles, and after adjusting the thickness and state of the rice, pushes it to the rice or vegetable outlet for smooth release from the rice or vegetable outlet. When a certain amount of porridge or vegetables falls out, the pneumatic mechanism blocks the dish or rice outlet, achieving the effect of automatic dish or rice discharge. At the same time, the rice or vegetables at the bottom of the barrel are pushed by two rotating blades provided at the bottom of the barrel to ensure the quality and stability of the discharged dishes or vegetables. The automatic vending machine using this solution can adapt to the vending methods of multiple dishes at the same time, has stronger adaptability, and at the same time, through the cooperation of structural components, realizes the function of automatic vending, which can effectively reduce labor and save costs. Moreover, this method is only an illustration of a preferred embodiment, but is not limited to this. When implementing the present invention, appropriate replacements and / or modifications can be made according to user needs.

[0120] like Figure 2 In another example, the stirring assembly located in the porridge bucket is configured to include:

[0121] The first rotating shaft 1131 and at least three layers of stirring mechanisms 1132 disposed thereon are used to cooperate with the positions of the layers of the porridge barrel to stir the porridge so that the consistency of the porridge can be adjusted and maintained when it is discharged;

[0122] The stirring mechanism at the bottom layer has a predetermined gap with the bottom of the barrel body to prevent damage to the bottom of the barrel body during the rotation and stirring process. Each stirring mechanism at each layer is configured to have at least two first stirring blades 1133, which are used to match any amount of rice in the porridge barrel to achieve a better stirring effect.

[0123] The stirring mechanisms at each layer are arranged to be staggered at a first predetermined angle. The predetermined angle design allows the rice at each layer inside the barrel to rotate along with the spiral during each rotation, resulting in a more excellent rotation effect and better consistency of the porridge in the barrel.

[0124] A trumpet-shaped first measuring cup 1134 is provided at the bottom of the barrel body at a position corresponding to the rice outlet. The trumpet-shaped first measuring cup 1134 installed at the bottom of the barrel body ensures that each portion of rice is basically uniform, and the male connector on the first measuring cup can be smoothly connected to the female connector of the external structure.

[0125] Among them, the first measuring cup is provided with a filtration mechanism (not shown) in a detachable manner, and the first measuring cup is equipped with a dry and porridge filter bucket that can be freely detached and automatically closed, which is configured as a conventional mesh filter plate to control the ratio of rice and water, while ensuring that the storage barrel does not leak during transportation, and the filter bucket can be opened smoothly, and the first measuring cup is provided with a first non-porous annular enclosure 1135 at a position that matches the direction of rice discharge, which is configured to be trumpet-shaped and is used to enclose the falling process of porridge to prevent it from falling out. The use of this solution makes it more effective when combined with an automatic vegetable vending machine, and can be coordinated with the specific porridge sold to have better quality, and this method is only an illustration of a preferred example, but is not limited to this. When implementing the present invention, appropriate replacements and / or modifications can be made according to user needs.

[0126] like Figure 3-7 In another example, the stirring components in the cooking bucket and the stir-frying bucket are configured to include:

[0127] The second rotating shafts 1231 and 1331 and at least two second stirring blades 1232 and 1332 are provided at the corresponding positions on the bottom of the barrel body to push the cooked food to the food outlet. The second stirring blades 1232 and 1332 can be provided as three blades, so as to smoothly push the food in the food outlet cavity to the food outlet through rotation, thereby preventing the food from piling up at the bottom of the barrel body and reducing the impact on the physical properties of the food during multiple food outlets.

[0128] The dish-supporting discs 1233 and 1333 are arranged parallel to the bottom of the barrel to limit the stirring blades. They are used to partition the interior of the barrel, reduce the impact on the physical properties of the dishes during multiple servings, and ensure that a large amount of dishes will not accumulate when serving at the serving port, affecting the serving effect;

[0129] The dish-carrying disc has a predetermined gap with the bottom of the barrel body due to the height of the second stirring blade, so as to form a dish-discharging cavity with a limited dish-discharging amount between the dish-carrying disc and the bottom of the barrel body. The dish-carrying disc is partitioned so that the dish will not be seriously damaged due to multiple rotations of the dish-discharging disc, and at the same time, it effectively prevents the dish-discharging port from being blocked by excessive accumulation of dishes during the dish-discharging process. The dish-carrying disc is provided with "8"-shaped dish-discharging openings 1234 and 1334 for connecting the inner cavity of the barrel body and the dish-discharging cavity. The dish-carrying disc is used to allow the dish in the barrel body to enter the dish-discharging cavity through the dish-discharging openings through rotation, and the dish in the dish-discharging cavity is replenished in time during the rotating dish-discharging process, so as to make the dish-discharging process smoother. At the same time, in the initial state, the position of the dish-discharging opening matches the position of the blocking component.

[0130] The second stirring blade is configured to have a second predetermined angle with the bottom surface of the barrel in its rotation direction. The stirring mechanism forms a 90-degree angle with the bottom round rod of the stirring rod on which it is installed, so that the food is delivered to the cup mouth in a timely manner. At the same time, the predetermined angle design ensures that the food at the bottom of the barrel can flow out during each rotation without causing damage to the physical properties of the food due to retention, and the rotation will not cause physical damage to the bottom of the barrel.

[0131] The bottom of the barrel body is provided with a second measuring cup 1235, 1335 at a position corresponding to the dish outlet, and the male head thereon is used to connect with the female head of other equipment to realize the transfer of dishes, and the design of the measuring cup can output the dishes in a quantitative manner. A second annular enclosure 1236 without holes is provided at a position cooperating with the second measuring cup in the cooking barrel. The second annular enclosure 1236 is configured in a trumpet shape to guide and limit the fall of the dishes, and at the same time facilitates the blocking piece to better combine with the annular enclosure to achieve a tight sealing effect, thereby preventing its position displacement from affecting the dish serving effect. A third annular enclosure 1336 with holes is provided at a position cooperating with the second measuring cup in the cooking barrel. The third annular enclosure 1336 with holes is configured in a hole shape to separate oil, vegetables and water when the dishes are transferred, so as to ensure the uniformity of each portion when the dishes are served, and there will be no situation where some dishes have more oil and some have no oil. The third annular enclosure 1336 with holes is configured in a trumpet shape to guide the dishes and facilitate the plug to seal the cup mouth. The cooking and frying barrels using this solution work in such a way that when the blocking component is lifted by the pneumatic mechanism, the rotating component rotates one or two circles, pushing the food to the food outlet, allowing it to fall out smoothly from the food outlet. When a fixed amount of food falls out, the pneumatic mechanism blocks the food outlet, achieving the effect of automatic food discharge. At the same time, two rotating blades provided at the bottom of the barrel body push the food at the bottom of the barrel body to ensure the quality and stability of the food discharge. This method is only an illustration of a preferred embodiment and is not limited to this. When implementing the present invention, appropriate replacements and / or modifications can be made according to user needs.

[0132] like Figure 2 In another embodiment, the blocking component located in the porridge bucket includes:

[0133] The first piston rod 1141 connected to the second power output shaft is used to drive the plug to move together with the first piston rod to complete the blocking operation of the rice outlet;

[0134] A first plug 1142 provided at the free end of the piston rod is used to switch the working state of the rice outlet;

[0135] A first guide sleeve 1143 is provided on the inner wall of the cover body and cooperates with the first piston rod. It is used to limit and guide the up and down reciprocating motion of the first piston to prevent it from deviating so that the rice outlet can be well sealed after each movement.

[0136] The limiting sleeve 1144 cooperates with the first guide sleeve to limit and guide the movement trajectory of the plugging component, thereby reducing the displacement of the first plug during its movement caused by porridge deposition;

[0137] A positioning rod 1145, one end of which is sleeved in the limiting sleeve and the other end of which is connected to the first plug, is used to cooperate with the guide sleeve to guide and orient its up and down movement, so that its piston rod can smoothly open the filter plate in the porridge measuring cup;

[0138] The first plug is provided with a first silicone sealing layer (not shown) at one end thereof facing the rice outlet, which is used to increase the sealing performance of the plug during operation and prevent water in the rice from overflowing during sealing.

[0139] A first elastic element 1146 cooperating with the first piston rod is provided inside the first guide tube sleeve, such as a spring. After the material barrel leaves the automatic rice vending machine, during the loading process, it provides sufficient external force to the piston rod silicone plug, so that it can better seal the rice outlet to prevent water in the rice from overflowing. When online, it ensures the sealing while also ensuring the equal amount of rice in each portion, while providing an elastic force to make its return action smoother. The guide tube sleeve can be designed on the side facing the plug to seal it and limit the position of the first elastic element. It can also be a gasket of other types, and the first guide tube sleeve is connected to the side wall of the barrel body through a matching connector to fix the first limiting sleeve.

[0140] A longitudinally distributed opening (not shown) is provided on one side of the first guide sleeve. The first guide sleeve is connected to the first piston rod via a connecting portion passing through the opening to guide and position the first piston rod when it moves up and down. The first guide sleeve having the opening is used to connect the limiting sleeve to the piston rod, facilitate cleaning of the elastic element, and provide the vertical movement trajectory and stroke position of the plug.

[0141] The first silicone sealing layer is fixed to the bottom of the plug by a matching circular fixing piece (not shown). The circular fixing piece ensures the sealing effect while improving the stability of the sealing layer. It also ensures the cleanliness after cleaning. The first silicone sealing layer can be detachably mounted with screws or bonded to the plug.

[0142] The fixed plate is equipped with prongs 1147 arranged in an inverted "V" pattern, facing the rice dispensing direction. These prongs are used to open the measuring cup and the filter mechanism therein through the movement of the blocking assembly, allowing the porridge to flow out smoothly. This solution, by installing the piston rod and the first guide sleeve, and adding a limiting sleeve and positioning rod to the blocking assembly, ensures that the measuring cup mouth closes accurately with each movement, preparing for the second rice dispense. This method is merely an illustration of a preferred embodiment and is not intended to be limiting. When implementing the present invention, appropriate replacements and / or modifications may be made based on user needs.

[0143] In another example as shown in 3-7, the blocking components located in the cooking bucket and the stir-frying bucket respectively include:

[0144] The second piston rods 1241 and 1341 connected to the second power output shaft are used to drive the plug to move together with the second piston rod to complete the blocking operation of the food outlet and push the food out;

[0145] The second plugs 1242 and 1342 provided at the free end of the second piston rod are used to switch the working state of the food outlet;

[0146] The second guide sleeves 1243 and 1343 are provided in the barrel body and cooperate with the second piston rod. They are used to limit and guide the up and down reciprocating motion of the second piston to prevent it from deviating, so that the food outlet can be well sealed after each movement.

[0147] The arc-shaped vegetable baffles 1244 and 1344 cooperate with the blocking assembly to separate the position where the blocking assembly moves from the position where the food is contained, thereby preventing the operation of the storage barrel from affecting the operation of the blocking assembly and also preventing the working state of the blocking assembly from affecting the properties of the food;

[0148] Wherein, the second plug is provided with a silicone sealing layer (not shown) at one end facing the food outlet;

[0149] The second guide tube sleeve is connected to the side wall of the vegetable retaining plate through matching fixing members 1246 and 1346, and is used to limit the position of the second guide tube sleeve in the barrel body. Of course, it can also be installed on the barrel cover, but it is not conducive to cleaning.

[0150] The bottom of the frying barrel is provided with an oil storage box 1347 which matches the oil outlet direction of the second measuring cup. It is used to separate and store the oil, vegetables and water when serving the dishes, thereby ensuring the quality of the dishes. A filter screen which matches the measuring cup is installed at the bottom of the barrel to achieve oil and water separation to ensure that each serving of food is evenly covered with oil and water. A cleaning hole 1348 and a corresponding oil drain valve (not shown) are provided on it. Through the function of the cleaning hole, it can complete the internal cleaning work by flushing, which is more convenient. At the same time, the excess oil stored inside is discharged through the oil drain valve to facilitate its flushing or connect with other mechanisms such as oil pumps and oil nozzles to realize the transportation of oil and water. A knife cup, cooperating with the second measuring cup, is located at the lower end of the second plug of the cooking bucket. The knife cup is used to push food to a predetermined position and cut through entangled food, allowing it to quickly separate from the cup wall and prepare for the next serving. Furthermore, a second elastic element 1245 is located within the second guide tube sleeve of the cooking bucket, cooperating with the second piston rod. This elastic element applies force to the plug during loading and operation, effectively sealing the food outlet and preventing leakage. This ensures that the measuring cup opening is accurately closed with each movement, allowing food to quickly separate from the cup wall and prepare for the next serving. The vegetable baffle prevents food from clogging the measuring cup opening and excessive breaking caused by repeated pushing, thereby improving the quality of the food. This embodiment is merely an example of a preferred embodiment and is not intended to be limiting. When implementing the present invention, appropriate replacements and / or modifications may be made based on user needs.

[0151] like Figure 8-9 In another embodiment, the device further includes a load-bearing plate and a food serving box 2 respectively matched with the food storage barrel group. The load-bearing plate provides support for the food storage barrel group, and the food serving box is configured to include:

[0152] The gate assembly 2100 cooperates with the vegetable storage bucket assembly of the automatic vegetable vending machine to realize quantitative vegetable dispensing. It is used to cooperate with the vegetable dispensing port of the storage bucket to deliver the vegetables to the predetermined position of the vegetable dispensing assembly;

[0153] The dish discharging assembly 2200 is provided below the gate assembly to cooperate with the gate assembly to push the dishes to the dish tray. The dish discharging assembly 2200 is used to receive the dishes output from the gate and push them to the designated location to complete the delivery of the dishes.

[0154] The middle plate 2110 of the gate assembly, through a first pneumatic mechanism (not shown) cooperating therewith, blocks the vegetable outlet of the vegetable storage bucket. The reciprocating motion of the middle plate switches the communication state between the vegetable outlet and the accommodating cavity of the vegetable outlet assembly. At the same time, the reciprocating motion of the middle plate can also be used to remove the vegetables hanging at the vegetable outlet so that they can fall smoothly into the vegetable outlet assembly. Depending on the different properties, the vegetable outlet has less or almost no residue, and the vegetable outlet has a better serving effect.

[0155] The tile-shaped push plate 2210 in the serving assembly pushes the dropped food to a predetermined position on the serving tray via a second pneumatic mechanism 2220. This push plate, perpendicular to the bottom of the serving assembly and in the shape of a tile, pushes the food inside the serving assembly completely onto the serving tray, completing a serving operation. This method is merely an illustration of a preferred embodiment and is not intended to be limiting. When implementing the present invention, appropriate replacements and / or modifications may be made based on user needs.

[0156] Specifically, the box body is provided with a pivotally connected splash plate 2230 near its outlet, which is used to partially block the porridge when it is sold so that it does not all flow out. When the porridge is discharged through the box body opening 2250, when a large amount or all of the porridge falls into the rice bowl, it splashes due to gravity.

[0157] Among them, the splash plate is provided with at least three strip openings 2231 for releasing internal pressure and slowing down the flow of fluid. The strip openings are used to release the pressure generated when the vegetable pushing board is pushed, so that the porridge inside can be slowly released.

[0158] The push board is provided with a push rod 2240 of a predetermined length for opening the splash guard at a predetermined stroke. The push rod is used to gradually push the splash guard open in advance when the push board reaches a certain stroke when serving dishes of different characteristics, so that the rice and dishes can all fall out smoothly.

[0159] The gate assembly also includes an upper plate 2120 connected to the vegetable storage barrel, on which a quick-connect female connector 2121 is provided via a flange. The female connector 2121 is used to cooperate with the male connector of the measuring cup on the automatic vegetable vending machine to achieve a detachable connection between the two. The female connector guides the output of the vegetables and cooperates with the vegetable outlet to facilitate the vegetables to fall into the trumpet-shaped first opening (not shown) in the vegetable dispensing assembly. The trumpet-shaped structural design can guide, cut off and prevent the vegetables from hanging.

[0160] The step 2130 or U-shaped lower plate matched with the box body of the dish serving assembly is used to provide a mounting position and a sliding position for the dish serving assembly. The use of the step-shaped structure is to form a certain height difference after installation, so that the dish pushing plate can contact the bottom plate of the middle plate, thereby making it have the function of scraping and cutting the dishes, and at the same time having the effect of saving costs.

[0161] The middle plate is provided with a trumpet-shaped second opening 2111 which matches the first opening. The working process of the dish serving box is that, in the initial state, the rear end of the middle plate and the measuring cup are in a closed state for serving dishes. After selecting and confirming the dish, the middle plate automatically moves backward, and the position of the measuring cup mouth of the material barrel is revealed (or the third opening can be aligned with the first and second openings). At this time, the dish serving channel is opened, and the chopped vegetables in the measuring cup mouth fall smoothly into the dish serving assembly through the position of the third opening. The middle plate of the gate closing plate then automatically moves in the opposite direction and returns to the initial state. That is, one dish serving operation is completed and it is waiting for the second operation.

[0162] like Figure 10-12 In another embodiment, the present invention further includes a food receiving bin 3 that cooperates with the food delivery box, which is configured to include:

[0163] The outer housing 3100 is used to encapsulate and isolate the internal components to prevent contamination. Slide rails 3310 are provided on opposite sides of the outer housing to allow the tray to slide inside the housing and to place the tray and unload the food according to different travel distances.

[0164] The tray 3200 cooperates with the slide rail to realize the entry and exit of the meal plate. It is used to support and position the meal plate to receive the user's placement of the meal plate, and after receiving the meal plate, it is transported to the meal outlet to realize the meal discharge operation;

[0165] A motorized push rod 3300 and a first motor 3310 are provided directly below the tray to provide power for the tray to be automatically moved in and out. The first motor transmits power to the motorized push rod, which in turn drives the position of the tray to move forward and backward, thereby achieving the tray's automatic movement in and out.

[0166] The housing is provided with a door 3400 for closing the vegetable compartment at the position where the dinner plate is placed. The door 3400 is used to seal the interior of the housing, protect the internal structure, and prevent external contamination.

[0167] The housing is positioned to cooperate with each door, and a plurality of fixing plates 3500 are used to form a frame-type door panel, which is used to fix the door, provide space for the door to slide left and right, and limit it at the same time;

[0168] The lower fixed plate is provided with a slide rail 3510 for the door to slide, and the door is provided with a pulley 3410 that cooperates with the slide rail. The cooperation between the slide rail and the pulley makes the door slide left and right more stable. The upper fixed plate can be provided with a U-shaped slide groove to enhance its stability after installation. Alternatively, slide rails can be provided on the opposite fixed plates to meet the needs of smooth manual door opening.

[0169] A second motor 3420 is provided at a relative position of each door, which is used to generate corresponding power and realize automatic opening and closing of the door in combination with other components. The second motor is connected to the housing or door panel through a matching fixing member 3421;

[0170] A V-shaped pulley 3430 is provided on the power output shaft of the second motor, which is used to coordinate the power output of the motor with other components through the action of the pulley to realize power transmission;

[0171] The oppositely arranged fixed plates are respectively provided with an adjusting wheel assembly 3440, which includes two pulleys respectively provided on the fixed plates on each side of the door panel, and is used to form a rectangular transmission structure layout in space through the action of the adjusting wheel assembly;

[0172] The V-shaped pulley and the regulating wheel assembly are connected by a matching transmission wire rope 3450, which connects the various components into one. The wire rope is pre-wound around the V-shaped pulley for at least one circle. The wire rope is used to provide a certain resistance during the transmission process through the winding, thereby making the door more stable during the left and right movement.

[0173] Each warehouse door is inserted into the wire rope through the connecting column 3460, which is used to connect the transmission wire rope and the warehouse door into one body through the action of the connecting column, and can move along with the movement of the wire rope. The wire rope is provided with a clamping ring at both ends of the insertion position of the connecting column, which can be set to a ring structure of twisted wire, and is used to limit the position of the connecting column on the wire rope through the position of the clamping ring, so that it has a margin during the movement, and at the same time, it can also ensure that its reciprocating motion affects the structural stability of the wire rope, thereby making it more stable during the later operation process. Moreover, this method is only an illustration of a preferred example, but is not limited to this. When implementing the present invention, appropriate replacements and / or modifications can be made according to user needs.

[0174] like Figure 13-18 In another example, the invention further comprises an automatic disk-taking device 4, which is configured to include:

[0175] A suction cup assembly 4100 for sucking up a single plate, which separates the single plate from the stacked plates through the suction force of the suction cup, facilitating the subsequent removal of the plates;

[0176] A support assembly 4200 for positioning a single plate after suction, which is used to receive and support the plate as it falls after the suction of the suction cup disappears;

[0177] A tray ejection assembly 4300 for ejecting a positioned single tray. This assembly is used to separate a single tray from the support assembly through a thrust force, allowing the tray to fall into a designated compartment door position. The compartment door is opened and closed by a cooperating cylinder.

[0178] The suction cup assembly is configured to include at least three suction cups 4110 that cooperate with the meal trays. The suction cups can be configured to be in a herringbone shape to correspond to the center of gravity of the gridded stainless steel meal trays of the prior art. Each suction cup is connected to a vacuum generator (not shown) through a corresponding gas conduit 4111. The vacuum generator generates an air pressure of about 5 MPa, which is connected through the corresponding three gas conduits that cooperate with the suction cups, so that the suction cups have a corresponding suction force to separate the meal trays from the stacked meal trays one by one, thereby enabling the meal trays to be taken out one by one. This scheme is used to separate the stacked meal trays one by one through the suction cup assembly, and to support the separated meal trays through the corresponding support assembly, so that when the suction of the suction cups is removed, they can be supported and limited so that they will not fall on the stacked meal trays. Then, the meal tray on the support assembly is pushed out to a specified position through the corresponding dish discharge assembly to realize the dish discharge operation, so that it can be used alone as a dish retrieval machine, or it can be coordinated with other equipment such as an automatic food vending machine to realize linkage operation. Furthermore, this method is only an illustration of a preferred embodiment and is not limited thereto. When implementing the present invention, appropriate replacements and / or modifications may be made according to user needs.

[0179] Specifically, the suction cup assembly further includes:

[0180] A mounting plate 4112 for limiting the position of the suction cup, which is used to cooperate with other structures to achieve fixed installation of the suction cup assembly;

[0181] A guide plate 4113 cooperates with the mounting plate and is used to guide and limit the operation of the suction cup by reciprocating through the action of the pneumatic mechanism;

[0182] The guide plate and the mounting plate are connected by at least three guide rods 4114 that match the positions of the suction cups. The guide rods and the guide plate cooperate to guide the motion trajectory of the suction cup assembly during its reciprocating process. The guide plate is connected to the mounting plate through a first pneumatic mechanism 4116 that penetrates the mounting plate. The pneumatic mechanism, such as a cylinder, is used to provide reciprocating power, so that the suction cups can reciprocate up and down simultaneously, thereby performing the suction and separation action of the plate.

[0183] The gas duct is provided with a buffer rod 4115 at a position cooperating with the guide plate and the mounting plate. The buffer rod is used to guide the movement of the suction cup during the movement process so that the force of the suction action is uniform. At the same time, the tightness with the dinner plate during the adsorption process is better and the suction is smoother.

[0184] Also included is a lifting assembly 4400 for lifting the stacked dinner plates to a predetermined position, comprising:

[0185] A first bracket 4410 is used to lift the carrying plate to a predetermined position corresponding to the suction cup, and is used to support and position the stacked plates;

[0186] A lifting mechanism 4411 cooperates with the first bracket, and is used to cooperate with the first bracket to lift the first bracket to a predetermined position through the power generated by the lifting mechanism to facilitate the operation of sucking the plate;

[0187] The lifting mechanism is configured to include a ball screw 4412 that cooperates with the first bracket at each corner, and is used to convert the rotational force generated by the cooperation of the sprockets into linear motion, so that the first bracket can reciprocate up and down as needed to achieve the lifting operation of the dinner plate;

[0188] A first sprocket 4413 is coupled to each ball screw and is used to transmit rotational force to the coupled ball screw;

[0189] The second sprocket 4414 is connected to the first sprocket through the chain 4415, and is used to transmit the force of the first motor to each first sprocket through the cooperation of the chain, thereby realizing the linkage of each ball screw;

[0190] The first motor 4416, connected to the second sprocket via a power output shaft, generates a rotational force that is applied to the second sprocket, thereby achieving the lifting operation. The ball screw and sprocket cooperate to achieve the up-and-down reciprocating motion of the first bracket, thereby achieving the lifting operation of the plate, allowing the suction cup to fill the empty plate within a limited suction range.

[0191] Also included is a second bracket 4417 that cooperates with the first bracket and is used to carry the spare stacked meal trays transferred to the first bracket;

[0192] Among them, a plurality of rotating shafts 4418 for the dining plates to roll are respectively provided on the first bracket and the second bracket. The second bracket is relatively fixed, and the rollers can rotate freely in the bracket. Therefore, the dining plates can be transported along their rotation direction through the rotating shafts thereon, and the interference between the dining plates and the brackets is significantly reduced, resulting in better pushing effect and greater stability.

[0193] It also includes a positioning assembly 4500 that cooperates with the first bracket, including a first positioning mechanism 4510, a second positioning mechanism 4511, a third positioning mechanism 4512, and a fourth positioning mechanism 4513 that respectively cooperate with the front, rear, top, and side positions of the dinner plates. The fourth positioning mechanism is a side positioning bar that can be distributed on the rear side of the first bracket and the rear and front sides of the second bracket to ensure that the dinner plates do not move forward, backward, left, or right during movement, which would affect the accuracy of the suction cups. The second positioning mechanism is configured as an electronic lock and is composed of a cylinder (not shown), a guide bar 521, and a positioning bend plate 522. It is used to achieve all-round protection for the stacked dinner plates during movement through positioning operations in different directions.

[0194] Wherein, the first positioning mechanism includes:

[0195] Two guide rods 4511 are provided on the front side of the frame to control the position of the tray during its up and down reciprocating motion. They cooperate with other rods to control the position of the stacked trays, preventing them from shaking during the motion and affecting the accuracy of the subsequent suction operation.

[0196] Slide blocks 4512 are respectively mounted on each guide rod, and are used to slide upward on the guide rod, thereby driving the positioning rod connected thereto to slide;

[0197] The positioning rod 4513 connected to each slider is used to provide an installation position for the positioning plate and drive it to reciprocate up and down, and the positioning plate 4514 with a bending portion is pivotally set on the positioning rod. The operation of the pivotal connection enables it to coordinate the positioning of stacked plates of different heights, and at the same time, it is convenient to operate when adjusting the plates.

[0198] The tray ejection assembly is configured to correspond to the support assembly to provide power to push the tray out of the second motor 4300, which is used to provide power and push the tray out of the support assembly through a screw transmission mechanism that cooperates with the second motor. It can also be replaced by a cylinder:

[0199] The support assembly comprises:

[0200] A second pneumatic mechanism 4210, which is used to achieve reciprocating operation through the force of a cylinder;

[0201] The bracket 4221 is connected to the power output end of the second pneumatic mechanism through a connecting rod, so as to enable the plate to pass through and achieve support through hinged deformation. It is used to pull the bracket hinged at the four corners through the reciprocating movement of the cylinder, so that it can be regularly transformed into a parallelogram and a rectangle under the action of force, so as to facilitate the passage of the plate and the positioning support;

[0202] Z-shaped positioning plates 4222 are positioned relative to the brackets to support and position the tray after it has been released from the suction cup assembly. Their function is to stably receive the tray after it loses suction, and their structural design is compatible with the tray's external structure. This solution employs a Z-shaped positioning plate mounted above the bracket, with a connecting rod connected to the cylinder. The tray-pushing motor is placed behind the deformable bracket, parallel to the cylinder, allowing the tray to be stably received after it has been released from the bracket, allowing it to be smoothly ejected.

[0203] The device also includes a tray pushing assembly 4600 that cooperates with the second bracket to push the dinner tray thereon to the first bracket, which includes:

[0204] A tray pusher 4610 is provided on one side of the second bracket, and includes a hidden tray pushing chain (not shown) and a housing matched therewith, and is used to drive the guide plate to achieve reciprocating motion through the action of the tray pushing chain;

[0205] A guide groove 4611 is provided above the bracket to guide the direction of the push plate, which is used to limit the movement direction of the push plate;

[0206] A tray pusher 4612 is provided at the front end of a hidden tray pusher chain, which, under the action of the chain, moves back and forth to push and position the trays during movement. This movement allows the trays to move on the rotating shaft, thereby achieving the effect of filling and conveying empty trays. A tray pusher employing this solution is fixed to the rear of the rear tray rack. The tray pusher chain and guide plate rod can be extended back and forth. The tray pusher chain is hidden in the tray pusher. Through the action of each tray pusher chain, the guide plate member moves back and forth, thereby pushing the trays from the second bracket to the first bracket, thereby filling the empty tray stack.

[0207] Two position sensors (not shown) are positioned on the frame, spaced a predetermined distance apart, to cooperate with the lifting assembly to detect the elevated position of the tray. This arrangement uses the two position sensors to limit the maximum height to which the top tray can rise. When a tray falls below the lower sensor, the lifting system adjusts the tray's position to accommodate the suction cup's travel. This defines the operating range for tray suction between the sensors, ensuring greater stability in the suction operation.

[0208] like Figure 19 In another embodiment, the invention further comprises a universal joint 5 for realizing a quick connection between the vegetable storage bucket group and the power assembly, which is configured to include:

[0209] The first connecting joint 5100 is provided in conjunction with the first power output shaft, and is mainly used to facilitate fixed engagement with the external motor output shaft, thereby enabling the motor output shaft to drive the shaft on the other side of the cross universal joint to rotate;

[0210] The cross-shaped second connecting section 5200 is fixed to one end of the first connecting section via a first latch 5300 ; the second connecting section is mainly fixed to the first connecting section and the female connector.

[0211] The female connector 5400 is fixedly mounted on the second connecting section via a second latch 5500 . The first connecting section and the female connector are arranged in a cross-shaped structure on the second connecting section.

[0212] And a connecting male head 5600 is provided in cooperation with the first power output shaft of the motor, which is provided therein in cooperation with the connecting female head through a third latch 5700, and the connecting male head can slide in a preset direction in the connecting female head. The provided connecting male head is used to connect an external transmission shaft. Since the connecting male head and the connecting female head can slide in cooperation with each other, when it is necessary to connect the external transmission shaft of the male head, the connecting male head is first pushed into the connecting female head, the transmission shaft is aligned with the connecting male head, and then the connecting male head is pulled out and fixedly matched with the transmission shaft. At this time, the third latch is passed through the connecting female head and the connecting male head respectively, so that the connecting male head is fixedly provided in the connecting female head at this time, and then the output shaft and the transmission shaft are combined through the two ends of the cross universal joint, so that power transmission can be carried out between the output shaft and the transmission shaft, which are fixed in position and have limited installation space. Its function is to allow a certain deflection margin when the various rotating components in the vegetable storage barrel are installed with the first power output shaft, thereby making the installation of the vegetable storage barrel with a certain weight faster and more convenient.

[0213] The second power output shaft of the pneumatic mechanism of the present invention and the sealing components in the vegetable storage barrel realize quick connection between each piston rod and the corresponding second power output shaft through a connecting nut.

[0214] Specifically, universal joint also includes:

[0215] A group of first Y-shaped connecting ears 5110 are relatively arranged at one end of the first connecting section, and the first pin is arranged on the first Y-shaped connecting ear. The arranged first Y-shaped connecting ear is mainly used for connecting the first connecting section and the second connecting section to improve the stability of the connection.

[0216] The second connection joint is configured as a cube structure, so that the second connection joint has multiple mounting surfaces to facilitate the connection and fixation between the first connection joint and the female connection head.

[0217] A second Y-shaped connecting lug 5410 is positioned opposite one end of the female connector. The second latch is mounted on this second Y-shaped connecting lug. Four extensions are provided on the other end of the female connector to form a retaining boss, which secures the male connector to the retaining boss. The second Y-shaped connecting lug is primarily used to connect the female connector to the second connecting section, improving the stability of the connection. The retaining boss at one end of the female connector ensures that one end of the male connector is retained within the female connector and prevents it from slipping out, enhancing the compactness and portability of the structure.

[0218] The male connector is configured as a T-shaped structure, with a square recessed hole 5610 at one end. The T-shaped structure allows the male connector to mate with the female connector and slide within it without falling out. The square recessed hole facilitates the connection between the male connector and the external drive shaft, making the connection between the two faster and more efficient.

[0219] like Figure 1 , in another embodiment, further comprising:

[0220] The oil spray assembly 6 is connected to the oil storage box on the cooking bucket, which is used to store the oil released by the cooking bucket so that a certain amount of oil and water can be sprayed on the surface of the cooking bucket after cooking to make the cooked food have better quality. The cleaning assembly (not shown) is used to clean the automatic food vending machine and is used to rinse the equipment after cooking to ensure that it is in a clean state that meets the needs of the next food vending machine.

[0221] Wherein, the oil injection assembly is configured to include:

[0222] The oil collector 6100 is connected to the oil storage box and is used to transfer oil and water through the oil valve on the oil storage box. A heating mechanism (not shown) is provided on the outside of the oil collector 6100. When the oil temperature is low, it heats the oil to ensure that the food after spraying is at an appropriate temperature and has better quality and taste. The heating mechanism can be configured as an electric heating rod, which has a simple structure and is easy to implement. It can cooperate with a temperature sensor to achieve automatic heating processing.

[0223] an oil pump (not shown) coordinated with the oil collector, for extracting a fixed amount of oil-water mixture from the oil collector so that it can be output as needed;

[0224] The semi-enclosed oil spray nozzle 6200, which is matched with the oil outlet of the oil pump and has a check valve, is used to spray a fixed amount of oil when the vegetables fall into the dinner plate through the force of the oil pump. Its working process is as follows: when the oil and water in the vegetable storage barrel are discharged into the oil collector through the oil valve, the temperature sensor can sense the oil temperature. When it is low, the electric heating rod switch is turned on to keep the oil at a certain temperature. The appropriate amount of oil and water is sprayed at the moment the vegetables fall into the dish box. After the dish is finished, the oil circuit can be automatically cleaned.

[0225] The cleaning assembly is configured to include:

[0226] A water pump and a wastewater collection box are provided in the frame of the automatic vegetable vending machine. The water pump can be provided at the bottom of the frame as needed. The water pump is connected to the cleaning water source and the water output is automatically controlled by switching its working state. The wastewater collection box can be provided in the middle of the frame to facilitate system integration. The wastewater collection box is used to collect wastewater after cleaning.

[0227] A cleaning water gun with a retractable water pipe is mounted on the frame 7 and located on one side of the vegetable storage bucket assembly. The water sprayed by the cleaning water gun has a certain pressure, ensuring that the cleanliness of the pipes meets the requirements for secondary sale. This method is merely an illustration of a preferred embodiment and is not intended to be limiting. When implementing the present invention, appropriate replacements and / or modifications may be made based on user needs.

[0228] The whole structure of the multifunctional automatic vegetable vending machine has four layers from top to bottom.
