[0062] Please refer to Figure 1 and Figure 6 This application provides a vending machine 1A, which includes a storage cabinet 1 and a dispensing cabinet 2. The storage cabinet 1 includes a storage cabinet body 11 and a product channel device 13, a cooling device 15, and a dispensing device 17, all housed within the storage cabinet body 11. The product channel device 13 is used to store goods 5. The storage cabinet body 11 includes a replenishment door 111 for placing goods 5 into the product channel device 13, and the cooling device 15 is used to freeze or refrigerate the goods 5. The dispensing cabinet 2 includes a dispensing cabinet body 20 and a delivery device 40, a heating device 50, and a heat preservation compartment 70, all housed within the dispensing cabinet body 20. The dispensing cabinet body 20 includes a dispensing surface 21 for users to retrieve goods, and the dispensing surface 21 and the replenishment door 111 are located on opposite sides of the vending machine 1A. The heating device 50 is used to heat the goods 5, and the heat preservation compartment 70 is used to store and keep the goods 5 warm. The dispensing device 17 is used to transport the goods 5 from the product channel device 13 to the dispensing cabinet 2. The delivery device 40 is used to transport the goods 5 delivered into the supply cabinet 2 to the heating device 50 or the insulated warehouse 70, and to transport the heated goods 5 to the insulated warehouse 70.

[0063] The goods sold by vending machine 1A include food, electrical appliances, and daily necessities. This article will only use food as an example for explanation. When food is item 5, it can be packaged food, such as a lunchbox containing food, bagged snacks, canned beverages, etc.; or it can be unpackaged food, such as bread, pastries, etc. That is, food can refer to the food itself or the food and its packaging, without restriction.

[0064] Food items to be sold in vending machine 1A are stored in the dispensing device 13 and kept at room temperature, refrigerated, or frozen depending on the operating setting of the refrigeration device 15. For example, the refrigeration device 15 has three operating settings: room temperature, refrigeration, and freezing, used to maintain the temperature of the storage cabinet 1 at room temperature, refrigerated, or frozen, respectively. After a user places an order, the dispensing device 17 removes the food from the dispensing device 13 and transports it to the supply cabinet 2. The delivery device 40 then delivers the food to the heating device 50 for heating and transports the heated food to the insulated compartment 70, where it awaits the user's pickup. In this way, vending machine 1A can freeze or refrigerate food in the dispensing device 13 for long-term storage; and it can heat frozen or refrigerated food to a suitable eating temperature and store it in the insulated compartment 70 to prevent the food from getting cold or spoiling due to long waiting times for the user to pick it up.

[0065] Vending machine 1A can sell various types of food and selectively heat the food according to its type. For example, when selling packaged snacks, the refrigeration unit 15 can be set to the normal temperature setting. After the snacks are sold, they do not need to be heated by the heating unit 50; instead, they are directly placed in the insulated compartment 70 for the user to pick up. When selling beverages, the refrigeration unit 15 can be set to the refrigeration setting. After the beverages are sold, they can be directly placed in the insulated compartment 70 for the user to pick up. The insulation of the compartment 70 keeps the beverages at a refrigerated temperature, preventing them from heating up and losing their refreshing taste when the outside temperature is too high. Alternatively, when selling hot drinks, the beverages can be heated by the heating unit 50 and then placed in the insulated compartment 70. The insulation of the compartment 70 maintains the temperature of the hot drinks, preventing them from cooling down. When vending machine 1A sells ice cream, the refrigeration unit 15 can be set to the freezing mode. After the ice cream is sold, it does not need to be heated by the heating unit 50; it is directly placed in the insulated compartment 70 to await customer pickup. The insulation of the insulated compartment 70 prevents the ice cream from melting while waiting for the customer to pick it up. When vending machine 1A sells ready-made meals, fast food, boxed meals, or other refrigerated / frozen cooked foods, the refrigeration unit 15 can be set to the refrigeration or freezing mode to prevent the food in the storage compartment 1 from spoiling. The sold food is heated to a suitable eating temperature by the heating unit 50 and then placed in the insulated compartment 70 to keep it warm, preventing the heated food from cooling down or spoiling.

[0066] The following description, in conjunction with the attached diagram, further illustrates the vending machine 1A.

[0067] Please see Figure 1 In some embodiments, the storage cabinet 11 and the supply cabinet 20 are two independent but interconnected cabinets, arranged longitudinally such that the retrieval surface 21 and the replenishment door 111 are located on opposite sides of the vending machine 1A. In one embodiment, the storage cabinet 11 and the supply cabinet 20 are connected and form an inseparable integral structure. Please refer to... Figure 3 and Figure 4 In another embodiment, the storage cabinet 11 is detachably connected to the supply cabinet 20 via a connecting unit 113 to facilitate disassembly, transportation, and maintenance. The connecting unit 113 comprises multiple dual-cabinet connectors; some of these connectors may be located on the back of one of the storage cabinet 11 and the supply cabinet 20, while others may be located on the top of the other of the storage cabinet 11 and the supply cabinet 20.

[0068] Please see Figure 2In some embodiments, the bottom of the storage cabinet 11 and / or the supply cabinet 20 may be provided with multiple casters 114 for supporting the vending machine 1A and facilitating its movement. The casters 114 may be trolleys capable of switching between fixed and moving modes. When the vending machine 1A needs to be transported, the casters 114 can be switched to moving mode to allow them to roll, facilitating transport; when the vending machine 1A is moved to the operating point, the casters 114 are switched to fixed mode to prevent them from rolling, thus fixing the vending machine 1A at the operating point.

[0069] Please see Figure 1 In some embodiments, vending machine 1A may further include a signal transceiver 3, which may be located on the top of storage cabinet 11 and / or the top of supply cabinet 20, for receiving or sending communication signals. Thus, a user can send a communication signal carrying order information via mobile phone. Upon receiving the communication signal, the signal transceiver 3 can initiate food preparation. This allows the user to place an order remotely and schedule a pickup time. Once the vending machine 1A has prepared the goods, it can arrange the food in the insulated compartment 70 according to the order of pickup times. The user can then retrieve the food from the pickup area 21 using a pickup code.

[0070] Please see Figure 1 In some embodiments, vending machine 1A may also include a monitor 4, which may be installed on top of the supply cabinet 20 to monitor the dispensing area 21. Since vending machine 1A is usually unattended, it is difficult to detect damage or malfunctions in a timely manner. Therefore, the monitor 4 allows for monitoring of the dispensing area 21 and transmits the monitoring footage to a remote monitoring station via a transceiver 3, facilitating timely intervention by remote personnel.

[0071] Please see Figure 6 and Figure 8 In some embodiments, the cargo channel device 13 may include a shelf 131 and a conveying module 133 disposed on the shelf 131. The shelf 131 is used to carry goods 5, and the conveying module 133 is used to convey the goods 5 on the shelf 131 to the picking device 17. In this way, the picking device 17 does not need to actively grab the goods 5 on the shelf 131. The picking device 17 only needs to move to the corresponding position on the shelf 131 and wait for the conveying module 133 to convey the goods 5, which simplifies the design of the picking device 17.

[0072] Please continue reading. Figure 6 and Figure 8 Specifically, the shelf 131 includes multiple shelves, which are stacked along the height direction of the storage cabinet 11. The retrieval device 17 can move along the height direction to retrieve goods 5 on different shelves 131.

[0073] Please combine Figure 6 More specifically, shelf 131 includes a panel 1311 and a wall 1313 extending upward from the edge of panel 1311. A receiving groove 1315 is formed between the wall 1313 and the panel 1311, and the receiving groove 1315 is used to place goods 5. The wall 1313 has a conveying port 1317 communicating with the receiving groove 1315. A conveying module 133 is used to push goods 5 out of the conveying port 1317. After goods 5 is ordered, the picking device 17 can move to the conveying port 1317 corresponding to the ordered goods 5, and the conveying module 133 can transfer goods 5 from the conveying port 1317 to the picking device 17.

[0074] Please see Figure 6 In some embodiments, the shelf 131 is mounted between two opposing inner sidewalls of the storage cabinet 11 (horizontally). The inner sidewalls are provided with a heat insulation layer to insulate the storage cabinet 11 from external heat, preventing external heat from being conducted into the storage cabinet 11 and improving the refrigeration / freezing effect of the storage cabinet 11.

[0075] Please see Figure 6 and Figure 8 In some embodiments, each shelf 131 is provided with multiple conveying modules 133, which divide the receiving slot 1315 into multiple sub-slots 13151, each sub-slot 13151 being used to receive at least one item 5. Each conveying module 133 is capable of pushing the item 5 in the corresponding sub-slot 13151 out of the conveying port 1317.

[0076] The conveying module 133 may include a pusher plate 1331, a synchronous track 1333, a synchronizing element 1335, and a pusher plate drive (not shown). The synchronous track 1333 is used to divide the receiving slot 1315 into multiple sub-slots 13151. The pusher plate 1331 is movably disposed on the synchronous track 1333. The synchronizing element 1335 connects the pusher plate 1331 and the pusher plate drive. The pusher plate drive is used to drive the synchronizing element 1335 to rotate, thereby causing the pusher plate 1331 to move along the synchronous track 1333, pushing the goods 5 in the corresponding sub-slot 13151 toward the conveyor opening 1317. In one embodiment, the pusher plate drive can be a motor. The synchronizing element 1335 may include a conveyor belt and a pulley. The motor can drive the pulley to rotate, and the rotation of the pulley drives the conveyor belt to rotate. The pusher plate 1331 is fixedly connected to the conveyor belt and moves within the sub-slot 13151 as the conveyor belt rotates, thereby pushing the goods 5 within the sub-slot 13151 to move. In other embodiments, the synchronizing element 1335 may also include a transmission chain and a synchronizing wheel, or a slide rail and a slider, etc., without limitation.

[0077] Please see Figure 6In some embodiments, a monitoring camera (not shown) may be installed inside the storage cabinet 11. The monitoring camera is used to monitor the remaining amount of goods 5 in the cargo channel device 13 so that staff can replenish the goods in a timely manner.

[0078] Please see Figure 6 and Figure 8 In some embodiments, the shelf 131 may be equipped with a gravity sensor 135. The gravity sensor 135 is used to detect the weight of the goods 5 carried on the shelf 131 to determine the remaining amount of goods 5 on the shelf 131. This allows the signal transceiver 3 to send an alert signal when the remaining amount of goods 5 is insufficient, reminding staff to replenish the goods in time. For example, each shelf 131 is equipped with a gravity sensor 135. By combining the data from the gravity sensor 135 corresponding to each shelf 131, the remaining amount of goods 5 in the entire cargo channel device 13 can be obtained. When the remaining amount of goods 5 in the entire cargo channel device 13 is lower than a preset threshold, the signal transceiver 3 sends an alert signal to remind staff to replenish the goods in time.

[0079] Please see Figure 6 In some embodiments, the refrigeration unit 15 is capable of generating cold air and delivering it to the cargo channel device 13. Please refer to... Figure 8 The plate 1311 has multiple air holes 13111 for cold air circulation, allowing cold air to flow through multiple shelves 131 to ensure that food on different shelves 131 is cooled. Specifically, please refer to... Figure 9 The refrigeration unit 15 may include an evaporator 151, a compressor 153, and a condenser 155, and is used to generate cold air to cool the storage cabinet 1. In some embodiments, the refrigeration unit 15 may also include a blower for blowing cold air toward the cargo channel device 13 to facilitate the flow of cold air through the shelves 131.

[0080] Please see Figure 1 and Figure 6 In some embodiments, the picking device 17 is located inside the storage cabinet 11, and the delivery device 40 is located inside the supply cabinet 20. This allows the picking device 17 to be positioned close to the delivery channel device 13, and the delivery device 40 to be positioned close to the insulated compartment 70 or the heating device 50, thus shortening the transport path for food by the picking device 17 and the delivery device 40. This allows for a more compact layout of the components in the vending machine 1A, facilitating its miniaturization.

[0081] In some embodiments, the picking device 17 can determine whether there are goods 5 remaining on the shelf 131 based on the data from the gravity sensor 135 corresponding to the shelf 131, so as to avoid the picking device 17 picking up goods from the shelf 131 where there are no goods 5.

[0082] Please see Figure 7In some embodiments, the picking device 17 may include a first picking track 171, a second picking track 173, and a picking module 175. The second picking track 173 is slidably connected to the first picking track 171 and is movable relative to the first picking track 171 along a first direction (Z1 / Z2). The picking module 175 is used to carry goods 5, and is connected to the second picking track 173 and is movable relative to the second picking track 173 along a second direction (X1 / X2). The second direction (X1 / X2) is substantially perpendicular to the first direction (Z1 / Z2). "Substantially perpendicular" means that the first direction (Z1 / Z2) and the second direction (X1 / X2) can be completely perpendicular, or that a certain angular variation is allowed in the actual design. In one embodiment, the included angle between the substantially perpendicular first direction (Z1 / Z2) and the second direction (X1 / X2) can be within the range of [85°, 95°]. For example, the included angle between the first direction (Z1 / Z2) and the second direction (X1 / X2) can be 85°, 86°, 87°, 88°, 89°, 90°, 91°, 92°, 93°, 94°, 95°, etc., which will not be listed here. The explanation of "substantially perpendicular" in the following text is the same.

[0083] For example, in Figure 6 In the illustrated embodiment, the first direction (Z1 / Z2) is vertical, and the second direction (X1 / X2) is horizontal. The picking module 175 can move relative to the second picking track 173 along the second direction (X1 / X2) to retrieve food at different horizontal positions on the same shelf 131. The second picking track 173 can move relative to the first picking track 171 along the first direction (Z1 / Z2) to move the picking module 175 to different shelf layers 131.

[0084] Please see Figure 3 The storage cabinet 11 also includes a delivery side wall 115 opposite to the replenishment door 111. The delivery side wall 115 has a delivery opening 1151 and a passage door 1153. The passage door 1153 is located at the delivery opening 1151 and is used to open or close the delivery opening 1151. A passage door drive 117 may be provided on the delivery side wall 115. The passage door drive 117 is connected to the passage door 1153 and is used to drive the passage door 1153 to move relative to the delivery opening 1151, so as to selectively close or open the delivery opening 1151. The passage door drive 117 may be a motor, cylinder, etc., and there is no limitation here.

[0085] In one embodiment, the passage door 1153 and the passage door drive 117 are disposed inside the storage cabinet 11, with the passage door 1153 slidably connected to the inner sidewall of the storage cabinet 11. The passage door drive 117 is used to drive the passage door 1153 to slide along the inner sidewall. Thus, the passage door 1153 and the passage door drive 117 do not occupy the space between the storage cabinet 11 and the supply cabinet 20, allowing the storage cabinet 11 and the supply cabinet 20 to be installed close together, reducing the food transport distance. In another embodiment, the passage door 1153 and the passage door drive 117 are disposed outside the storage cabinet 11, with the passage door 1153 slidably connected to the outer sidewall of the storage cabinet 11. The passage door drive 117 is used to drive the passage door 1153 to slide along the outer sidewall. This avoids the passage door drive 117 operating in low-temperature environments, thereby improving its service life.

[0086] Please see Figure 4 The supply cabinet 20 may also include an inlet side wall 22 opposite to the picking surface 21. The inlet side wall 22 is opposite to the outlet side wall 115 and is provided with an inlet 221 and a closing door 223. The closing door 223 is located at the inlet 221 and is used to open or close the inlet 221. Please refer to... Figure 3 With the outlet 1151 open at the passageway door 1153, the inlet 221 is opposite to and connected to the outlet 1151. Please refer to... Figure 6 and Figure 7 The picking module 175 is used to transport goods 5 through the outlet 1151 and inlet 221 into the supply cabinet 20. When no goods 5 are being transported from the storage cabinet 11 to the supply cabinet 20, the passage door 1153 closes the outlet 1151, and the closing door 223 closes the inlet 221 to isolate the cold air in the storage cabinet 11 and prevent it from entering the supply cabinet 20. When the picking module 175 is transporting goods 5 from the storage cabinet 11 to the supply cabinet 20, the passage door 1153 opens the outlet 1151, and the closing door 223 opens the inlet 221, allowing the picking module 175 to deliver the goods 5 into the supply cabinet 20.

[0087] Please refer to the following: Figure 4 and Figure 6 The supply cabinet 2 may also include a conveying device 30 housed within the supply cabinet body 20. The conveying device 30 is located at the inlet 221 and is used to receive goods 5 transferred from the picking module 175.

[0088] In some embodiments, the picking device 17 also includes a position sensor (not shown) disposed on the picking module 175. The position sensor is used to detect the position of the picking module 175 relative to the outlet 1151. When the picking module 175 reaches the preset position, the channel door drive 117 drives the channel door 1153 to move to open the outlet 1151, and the closing door 223 opens the inlet 221, so that the picking module 175 can unload the goods 5 onto the conveying device 30.

[0089] Please see Figures 10 to 12 The conveying device 30 includes a frame 31 and a drive assembly 33, with the drive assembly 33 mounted on the frame 31. The frame 31 includes two oppositely arranged side plates 311 and two oppositely arranged guide shaping plates 313. The two guide shaping plates 313 are respectively mounted on the two side plates 311. The drive assembly 33 includes a conveying drive component 331, two rollers 332, and a conveyor belt 333. The two rollers 332 are spaced apart from each other and rotatably mounted on the two side plates 311. The conveyor belt 333 is wound around the two rollers 332 and is used to carry goods 5 ( Figure 6 (As shown). The conveyor drive 331 is used to drive the roller 332 to rotate so as to drive the conveyor belt 333 to move. When the conveyor belt 333 drives the cargo 5 to move, the guide shaping plate 313 is used to adjust the posture of the cargo 5.

[0090] The conveying device 30 has a guide shaping plate 313 on the side plate 311 of the frame 31. When the conveyor belt 333 moves the goods 5, the guide shaping plate 313 can adjust the posture of the goods 5 so that the posture of the goods 5 can easily reach the posture required by the delivery device 40 to pick up and put down the goods 5 in the next stage. Thus, the delivery device 40 can accurately pick up the goods and improve the success rate of the transfer of goods 5.

[0091] Please see Figure 10 The two side plates 311 are spaced apart from each other. In one example, the two side plates 311 extend in parallel directions, that is, the two side plates 311 extend in the same direction. In another example, the two side plates 311 extend in different directions, that is, the two side plates 311 extend in intersecting directions.

[0092] Please combine Figure 11 In some embodiments, along the third direction Y2 of the transport of goods 5, the opening size between the guide shaping plates 313 gradually decreases first, and then remains constant. When the conveyor belt 333 moves the goods 5, after the goods 5 comes into contact with the guide shaping plates 313, its posture is adjusted along the extension direction of the guide shaping plates 313, so that the posture of the goods 5 can easily reach the posture required by the delivery device 40 to pick up and put down the goods 5 in the next stage.

[0093] Please see Figure 10In some embodiments, the guide shaping plate 313 may be made of an elastic material such as an elastic plastic sheet. Within a certain range, the guide shaping plate 313 can automatically adjust the opening size according to the size of the goods 5, thus allowing for posture adjustment for goods 5 of different sizes. In other embodiments, the guide shaping plate 313 may be made of a material that combines elasticity and rigidity, such as a steel sheet. This not only allows for automatic adjustment of the opening size to meet the posture adjustment needs of goods 5 of different sizes, but also strengthens the guide shaping plate 313 and extends its service life.

[0094] Further, please refer to Figure 10 and Figure 12 In some embodiments, the frame 31 may further include a baffle plate 315. The baffle plate 315 is connected between the two side plates 311 and is located at the first end 317 of the frame 31. The second end 319 of the frame 31 has a conveying port 318, which is opposite to the first end 317. The two side plates 311 and the baffle plate 315 form a receiving space 310, and the conveyor belt 333 is located inside the receiving space 310. When the conveyor belt 333 is transporting goods 5, the baffle plate 315 is used to block the goods 5 on the conveyor belt 333 to prevent the goods 5 from moving too far and falling off.

[0095] Please see Figure 10 and Figure 12 In some embodiments, the guide shaping plate 313 may include a first connecting portion 3131, a first guide portion 3133, a second guide portion 3135, and a second connecting portion 3137. The first connecting portion 3131 is mounted on the side plate 311. The first guide portion 3133 is obliquely connected to the first connecting portion 3131 and extends toward the baffle plate 315. The second guide portion 3135 is obliquely connected to the first guide portion 3133 and extends toward the baffle plate 315. The second connecting portion 3137 is connected to the second guide portion 3135 and mounted on the baffle plate 315. Along the third direction Y2 of the transport of the cargo 5, the opening size between the two first guide portions 3133 gradually decreases, and the opening size between the two second guide portions 3135 remains consistent, allowing the cargo 5 to adjust its posture after contacting the guide shaping plate 313. In other embodiments, due to the size limitation of the conveying device 30, in order to ensure that the goods 5 will not be blocked by the guide shaping plate 313 during the conveying process, thereby preventing the goods 5 from moving forward, the opening size between the two first guide parts 3133 and the opening size between the two second guide parts 3135 can be gradually reduced, so as to meet the conveying needs of various conveying devices 30 while the conveying device 30 can still adjust the posture of the goods 5.

[0096] Further, please refer to Figure 10 and Figure 11In some embodiments, the frame 31 may further include a base plate 316. The two side plates 311, the baffle plate 315, and the base plate 316 form a receiving space 310, within which the conveyor belt 333 is located. The base plate 316 is welded between the two side plates 311, making the frame 31 more stable and preventing insufficient strength of the conveyor belt 333 from causing transport failure of the goods 5, thus ensuring the stability of the transport of the goods 5 within the receiving space 310.

[0097] In some embodiments, the bottom of the baffle plate 315 is slightly higher than the upper surface of the base plate 316, i.e., there is a gap 3160 between the baffle plate 315 and the upper surface of the base plate 316. This reduces the material used in the fabrication of the conveying device 30 and exposes one side of the conveying drive member 331 (the side facing the first end 317) outside the conveying device 30, enhancing the heat dissipation of the conveying drive member 331 and preventing overheating, which could lead to the failure of conveying the goods 5. In other embodiments, the bottom of the baffle plate 315 is flush with the upper surface of the base plate 316, i.e., there is no gap 3160 between them. In this case, the base plate 316 serves as a stable connection. Thus, without increasing the area occupied by the conveying device 30, the stability of the conveying device 30 is enhanced, preventing the conveying device 30 from tilting and collapsing when the baffle plate 315 blocks excessively heavy goods 5.

[0098] Please refer to the following: Figure 10 and Figure 11 In some embodiments, the drive assembly 33 may further include a first pulley 334, a second pulley 335, and a timing belt 336. The transmission drive 331 is mounted on one of the side plates 311 and located at the second end 319. The output shaft of the transmission drive 331 is connected to the first pulley 334, and the timing belt 336 is sleeved on the first pulley 334 and the second pulley 335. The transmission drive 331 drives the first pulley 334 to rotate, thereby driving the second pulley 335 to rotate via the timing belt 336, thus initiating the movement of the transmission belt 333. In another embodiment, the transmission drive 331 may also be mounted on the base plate 316 to reduce the load on the side plate 311, improve the stability of the side plate 311, and prevent damage to the side plate 311 from causing the failure of cargo 5 transmission.

[0099] Please see Figure 10In some embodiments, the conveying device 30 may further include a positioning sensor 35 to detect whether the cargo 5 has reached a preset area. In one embodiment, the positioning sensor 35 is a distance sensor used to detect the distance between the cargo 5 and the positioning sensor 35. For example, the positioning sensor 35 is an infrared distance sensor, which calculates the distance between the light emitted by the positioning sensor 35 and the light reflected by the cargo 5 by collecting the time between the light emitted by the positioning sensor 35 and the light reflected by the cargo 5. The obtained distance is used to determine whether the cargo 5 has reached the preset area. In another embodiment, the positioning sensor 35 may also be an image sensor, which acquires an image of the cargo 5 and then analyzes the size or clarity of the cargo 5 in the image to determine whether the cargo 5 has reached the preset area.

[0100] Please see Figure 13 and Figure 14 The delivery device 40 includes a base 41, two opposing clamping plates 42, a clamping drive structure 43, and a moving drive structure 46. The two opposing clamping plates 42 are respectively mounted on opposite first sides 401 and second sides 402 of the base 41. Each clamping plate 42 is provided with a moving structure, and the two moving structures are arranged opposite each other and jointly used to carry goods 5. The clamping drive structure 43 is at least partially disposed on the base 41 and is used to drive the two clamping plates 42 to move along a second direction (X1 / X2) from the first side 401 to the second side 402, so as to move closer or further apart from each other and clamp or release the goods 5. The moving drive structure 46 is at least partially mounted on the clamping plates 42 and is used to drive the moving structures to move relative to the clamping plates 42 along a third direction (Y1 / Y2), which intersects with the second direction (X1 / X2).

[0101] The delivery device 40 of this application clamps or releases goods 5 by driving two opposing clamps 42 to move along a second direction (X1 / X2). Compared with the traditional pallet and pusher form, it can pick up and handle goods 5 of various different shapes and sizes without designing different delivery devices 40 for goods 5 of different shapes and sizes, thus improving the versatility of the delivery device 40. In addition, since the delivery device 40 is also provided with a moving structure that can move relative to the clamps 42 along a third direction (Y1 / Y2), when the goods 5 are carried on the moving structure, even if the clamps 42 remain stationary in the third direction (Y1 / Y2), the moving structure can still drive the goods 5 to move in the third direction (Y1 / Y2), which is beneficial to the transfer of goods 5.

[0102] Additionally, please see Figure 23The vending machine 1A may also include a first delivery track 491 and a second delivery track 493. A delivery device 40 is disposed on the first delivery track 491 and is movable relative to the first delivery track 491 along a first direction (Z1 / Z2). The first delivery track 491 and the second delivery track 493 are slidably connected and the device is movable relative to the second delivery track 493 along a second direction (X1 / X2), the second direction (X1 / X2) being substantially perpendicular to the first direction (Z1 / Z2).

[0103] Please refer to the following: Figure 13 and Figure 14 The base 41 includes a bottom wall 411 and a first side wall 412, a second side wall 413, a third side wall 414, and a fourth side wall 415 connected in sequence. The first side wall 412, the second side wall 413, the third side wall 414, and the fourth side wall 415 are all disposed on the bottom wall 411 and together with the bottom wall 411 form a receiving cavity 416. The base 41 includes a first side 401 and a second side 402 opposite to each other. The first side wall 412 is located on the first side 401 of the base 41, and the second side wall 413 is located on the second side 402 of the base 41.

[0104] Two opposing clamping plates 42 are respectively mounted on opposite first sides 401 and second sides 402 of the base 41. Each clamping plate 42 is provided with a movable structure. The two movable structures are arranged opposite each other and are used to carry the cargo 5. For example, in some embodiments, the clamping plate 42 includes a first plate 421, a second plate 422, and an extension plate 423. The movable structure is slidably mounted on the first plate 421, and the second plate 422 extends from the first plate 421 and into the base 41, that is, into the receiving cavity 416. The extension plate 423 extends from the junction of the first plate 421 and the second plate 422 toward the first side 401 or the second side 402 and is located outside the base 41, that is, the extension plate 423 is located on the side of the bottom wall 411 away from the receiving cavity 416. For example, the extension plate 423 of the clamping plate 42 located on the first side 401 of the base 41 extends to the second side 402, and the extension plate 423 of the clamping plate 42 located on the second side 402 of the base 41 extends to the first side 401.

[0105] The clamping drive structure 43 is at least partially mounted on the base 41 and is used to drive the two clamping plates 42 to move along a second direction (X1 / X2) from the first side 401 to the second side 402 of the base 41, so as to move closer or further apart from each other and clamp or release the goods 5. When the two opposing clamping plates 42 move closer to each other, they can also drive the two moving structures to move closer to each other, at which time the goods 5 can be clamped between the two clamping plates 42, and the opposite ends of the goods 5 can be respectively supported on the two moving structures; when the two opposing clamping plates 42 move further apart from each other, they can also drive the two moving structures to move further apart from each other, so as to release the goods 5 clamped between the clamping plates 42.

[0106] For example, when it is necessary to transport goods 5, the delivery device 40 can be moved to the location where goods 5 are stored. Then, the clamping drive structure 43 drives the two clamps 42 to move closer to each other to clamp the goods 5 between the two clamps 42. Then, the delivery device 40 holding the goods 5 is moved to the designated position. Subsequently, the clamping drive structure 43 drives the two clamps 42 to move away from each other to release the goods 5. In this way, the delivery of goods 5 is completed.

[0107] Specifically, in some embodiments, the clamping drive structure 43 may include a clamping drive member 431, a first lead screw 432, and a second lead screw 433. The clamping drive member 431 is mounted on a base 41. Two clamping plates 42 pass through both ends of the first lead screw 432, and it is rotatably fixed to a first side 401 and a second side 402 of the base 41. Two clamping plates 42 also pass through both ends of the second lead screw 433, and it is rotatably fixed to the first side 401 and a second side 402 of the base 41. Both the second lead screw 433 and the first lead screw 432 extend along a second direction (X1 / X2). The clamping drive member 431 is used to drive the first lead screw 432 and / or the second lead screw 433 to rotate, thereby causing the two clamping plates 42 to move towards or away from each other. Further, the first lead screw 432 and the second lead screw 433 pass through the second plate 422 of the clamping plates 42. That is, the second plate 422 of the clamping plate 42 is movably connected to the base 41 through the first lead screw 432 and the second lead screw 433.

[0108] like Figure 14 As shown, in some embodiments, the opposite ends of the first lead screw 432 extend along a second direction (X1 / X2), that is, the opposite ends of the first lead screw 432 extend from the first side 401 of the base 41 to the second side 402, and one end of its opposite ends passes through the second plate 422 of one of the clamping plates 42 and is rotatably fixed to the first side wall 412; the other end passes through the second plate 422 of another clamping plate 42 and is rotatably fixed to the second side wall 413. Similarly, the opposite ends of the second lead screw 433 extend along a second direction (X1 / X2), that is, the opposite ends of the second lead screw 433 extend from the first side 401 of the base 41 to the second side 402, and one end of its opposite ends passes through the second plate 422 of one clamping plate 42 and is rotatably fixed to the first side wall 412; the other end passes through the second plate 422 of another clamping plate 42 and is rotatably fixed to the second side wall 413. Driven by the clamping drive 431, the first lead screw 432 and the second lead screw 433 can rotate, so that the two clamping plates 42 sleeved on the first lead screw 432 and the second lead screw 433 can move.

[0109] For example, in some embodiments, the clamping drive member 431 includes two members, which are respectively connected to the first lead screw 432 and the second lead screw 433 to drive the first lead screw 432 and the second lead screw 433 to rotate synchronously. For example, in some embodiments, both clamping drive members 431 are mounted on the side of the first sidewall 412 away from the receiving cavity 416. One end of the first lead screw 432 passes through one of the clamping plates 42 and is rotatably fixed to the second sidewall 413 of the base 41; the other end passes through the other clamping plate 42 and the first sidewall 412 in sequence and is connected to the output shaft of one of the clamping drive members 431. Similarly, one end of the second lead screw 433 passes through one of the clamping plates 42 and is rotatably fixed to the second sidewall 413 of the base 41; the other end passes through the other clamping plate 42 and the first sidewall 412 in sequence and is connected to the output shaft of the other clamping drive member 431. Two clamping drive members 431 drive the first lead screw 432 and the second lead screw 433 to rotate synchronously, so that the two clamping plates 42 move along the second direction (X1 / X2). Since the first lead screw 432 and the second lead screw 433 rotate synchronously, the different speeds of the different ends of the clamping plates 42 can be avoided, which is beneficial to the overall movement of the clamping plates 42.

[0110] Of course, in some embodiments, both clamping drive members 431 may be disposed on the second side wall 413, or in some embodiments, one clamping drive member 431 may be disposed on the first side wall 412 and the other clamping drive member 431 may be disposed on the second side wall 413. There are no restrictions on this.

[0111] For example, please refer to Figure 14 In some embodiments, the clamping drive member 431 can be a single unit. In this case, the clamping drive structure 43 can further include a driven component 434. The clamping drive member 431 drives the first lead screw 432 and the second lead screw 433 to rotate synchronously through the driven component 434. Thus, under the action of the driven component 434, one clamping drive member 431 can simultaneously drive the first lead screw 432 and the second lead screw 433 to rotate synchronously. Compared with setting two clamping drive members 431 to drive the first lead screw 432 and the second lead screw 433 respectively, on the one hand, one clamping drive member 431 can be reduced, thereby reducing the manufacturing cost of the delivery device 40; on the other hand, the synchronicity of the rotation of the first lead screw 432 and the second lead screw 433 can be guaranteed, which is beneficial to the overall movement of the clamping plate 42.

[0112] Specifically, please combine Figure 15 and Figure 16In some embodiments, the driven component 434 includes a first rotating wheel 4341, a second rotating wheel 4342, a third rotating wheel 4343, a fourth rotating wheel 4344, and a timing belt 4345. The first rotating wheel 4341 is connected to the output shaft of the clamping drive member 431. The second rotating wheel 4342 is sleeved on the first lead screw 432 and cooperates with the first rotating wheel 4341. The third rotating wheel 4343 is sleeved on the first lead screw 432 and can rotate with it. The fourth rotating wheel 4344 is sleeved on the second lead screw 433. The timing belt 4345 is wound around the third rotating wheel 4343 and the fourth rotating wheel 4344 to drive the fourth rotating wheel 4344 to rotate with the third rotating wheel 4343. Thus, when the output shaft of the clamping drive member 431 rotates, it can drive the first rotating wheel 4341 connected to its output shaft to rotate, thereby driving the second rotating wheel 4342, which cooperates with the first rotating wheel 4341, to rotate. The rotation of the second rotating wheel 4342 drives the first lead screw 432 to rotate, causing the third rotating wheel 4343, which is sleeved on the first lead screw 432, to rotate as well. The rotation of the third rotating wheel 4343 drives the synchronous belt 4345 to move, thereby causing the fourth rotating wheel 4344 to rotate in tandem with the third rotating wheel 4343, which in turn drives the second lead screw 433, which is sleeved on the fourth rotating wheel 4344, to rotate. In this way, the clamping drive member 431 drives the first lead screw 432 and the second lead screw 433 to rotate synchronously through the driven component 434.

[0113] It should be noted that in some embodiments, the clamping drive member 431 is fixed to the base 41 by the first support 417 and housed in the receiving cavity 416. Since the clamping drive member 431 is housed in the receiving cavity 416, compared to placing the clamping drive member 431 outside the base 41, it not only protects the clamping drive member 431 but also reduces the size of the delivery device 40. Furthermore, in some embodiments, the first rotating wheel 4341 and the second rotating wheel 4342 can be gears, and the first rotating wheel 4341 meshes with the second rotating wheel 4342. Thus, when the clamping drive member 431 drives the first rotating wheel 4341 to rotate, it can drive the meshed second rotating wheel 4342 to rotate. Of course, in some embodiments, the first rotating wheel 4341 and the second rotating wheel 4342 can also be movably connected by a conveyor belt, as long as the rotation of the first rotating wheel 4341 can drive the rotation of the second rotating wheel 4342; no limitation is imposed here.

[0114] Please see Figure 16In some embodiments, the first lead screw 432 has a positive thread section 403 and a negative thread section 405 at its opposite ends, and the second lead screw 433 also has a positive thread section 403 and a negative thread section 405 at its opposite ends. One clamping plate 42 is fitted with a nut onto the positive thread section 403 of the first lead screw 432 and the positive thread section 403 of the second lead screw 433, and another clamping plate 42 is fitted with a nut onto the negative thread section 405 of both the first lead screw 432 and the second lead screw 433. Since the two clamping plates 42 are respectively fitted onto the positive thread section 403 and the negative thread section 405 of the lead screws (including the first lead screw 432 and the second lead screw 433), the two clamping plates 42 can move in opposite directions when the first lead screw 432 and the second lead screw 433 rotate, that is, the two clamping plates 42 can move towards or away from each other. For example, in one instance, when the first lead screw 432 and the second lead screw 433 rotate clockwise under the drive of the clamping drive member 431, the clamping plate 42 located on the first side 401 of the base 41 moves towards the second side 402, and the clamping plate 42 located on the second side 402 of the base 41 moves towards the first side 401, that is, the two clamping plates 42 move towards each other; when the first lead screw 432 and the second lead screw 433 rotate counterclockwise under the drive of the clamping drive member 431, the clamping plate 42 located on the first side 401 of the base 41 moves away from the second side 402, and the clamping plate 42 located on the second side 402 of the base 41 moves away from the first side 401, that is, the two clamping plates 42 move away from each other.

[0115] It should be noted that the clamping plate 42 can only move within the threaded area (including both positive and negative threads), such as... Figure 16 As shown, the second rotating wheel 4342 and the third rotating wheel 4343, which are sleeved on the first lead screw 432, are both located between the positive thread section 403 and the negative thread section 405 of the first lead screw 432. The fourth rotating wheel 4344, which is sleeved on the second lead screw 433, is also located between the positive thread section 403 and the negative thread section 405 of the second lead screw 433. That is, the second rotating wheel 4342, the third rotating wheel 4343, and the fourth rotating wheel 4344 are all located outside the movement stroke of the clamping plate 42. This can prevent the second rotating wheel 4342, the third rotating wheel 4343, and the fourth rotating wheel 4344 from blocking the movement of the clamping plate 42, thereby ensuring the normal operation of the delivery device 40.

[0116] Please see Figure 17In some embodiments, the clamping drive structure 43 may further include a guide assembly 435. The guide assembly 435 includes a slide rail 4351 and a slider 4352, one of which is disposed on the bottom wall 411 of the base 41, and the other on the extension plate 423 of the clamping plate 42. The slider 4352 cooperates with the slide rail 4351 to slide along a second direction (X1 / X2), wherein the slide rail 4351 extends along the second direction (X1 / X2). For example, as... Figure 17 As shown, the slide rail 4351 is located on the side of the bottom wall 411 away from the receiving cavity 416, and the slider 4352 is located on the side of the extension plate 423 of the clamping plate 42 near the second plate 422. The slider 4352 can cooperate with the slide rail 4351. During the movement of the clamping plate 42, the slider 4352 can move along the second direction (X1 / X2) on the slide rail 4351. In this way, the cooperation between the slider 4352 and the slide rail 4351 guides the movement of the clamping plate 42 relative to the base 41 along the second direction (X1 / X2), making the opposing or backward movement of the clamping plate 42 more stable.

[0117] Please see Figure 13 and Figure 18 In some embodiments, at least one clamping plate 42 may include a positioning member 424 extending from the extension plate 423 toward a first side 401 or a second side 402. Specifically, if the clamping plate 42 located on the first side 401 of the base 41 includes the positioning member 424, then the positioning member 424 of the clamping plate 42 extends from the extension plate 423 toward the second side 402; if the clamping plate 42 located on the second side 402 of the base 41 includes the positioning member 424, then the positioning member 424 of the clamping plate 42 extends from the extension plate 423 toward the first side 401.

[0118] At this time, the delivery device 40 may also include a sensing component 47, which is disposed on the bottom wall 411 of the base 41 and located outside the base 41, that is, the sensing component 47 is disposed on the side of the bottom wall 411 near the extension plate 423. The sensing component 47 cooperates with the positioning member 424 to detect whether the clamping plate 42 is located at the first limit position for clamping the goods 5 and the second limit position for releasing the goods 5. In this way, it is possible to detect whether the clamping plate 42 has moved into place, so as to avoid the situation that the goods 5 cannot be accurately picked up or placed due to the clamping plate 42 not moving into place.

[0119] It should be noted that each clamping plate 42 has a corresponding first limit position for clamping the goods 5 and a second limit position for releasing the goods 5. When both clamping plates 42 are at their respective first limit positions, the goods 5 can be clamped between the two clamping plates 42; when both clamping plates 42 are at their respective second limit positions, the goods 5 clamped between the two clamping plates 42 can be released. In some embodiments, the number of sensing components 47 can be two. In this case, both clamping plates 42 are provided with positioning members 424, and the two sensing components 47 cooperate with the positioning members 424 on the two clamping plates 42 respectively to detect whether the two clamping plates 42 are at the first limit position for clamping the goods 5 and the second limit position for releasing the goods 5. Since two sensing components 47 are used to detect the two clamping plates 42 respectively, the accuracy of detection can be improved. Of course, in some embodiments, during the rotation of the first lead screw 432 and the second lead screw 433, the two clamping plates 42 sleeved at both ends move the same distance, and the two clamping plates 42 can simultaneously reach their respective first and second limit positions. In this case, the number of sensing components 47 can be one. The sensing component 47 is used to cooperate with the positioning member 424 of one of the clamping plates 42 to detect whether the clamping plate 42 is located at the first limit position of clamping the goods 5 and the second limit position of releasing the goods 5, thereby determining whether the two clamping plates 42 are located at the first limit position of clamping the goods 5 and the second limit position of releasing the goods 5. Compared with detecting the two clamping plates 42 separately by two sensing components 47, the number of components in the delivery device 40 can be reduced, thereby reducing the weight and cost of the delivery device 40.

[0120] In the embodiments described below, the example is the cooperation between a sensing component 47 and the positioning member 424 of one of the clamping plates 42. Please refer to... Figure 13 and Figure 18In some embodiments, the sensing component 47 includes a first sensor 471 and a second sensor 472, both of which are disposed on the bottom wall 411 of the base 41. The first sensor 471 is located at a position corresponding to a first extreme position, and the second sensor 472 is located at a position corresponding to a second extreme position. That is, the first sensor 471 is closer to the center of the base 41 than the second sensor 472. Each sensor (including the first sensor 471 and the second sensor 472) includes a transmitting part (not shown) and a receiving part (not shown). The transmitting part is used to emit a detection signal toward the second plate 422 of the clamping plate 42 in the direction toward the first plate 421, and the receiving part is used to receive the reflected detection signal. The positioning member 424 includes a body 4241 and a through hole 4242 formed on the body 4241. If a detection signal is incident on the body 4241, the body 4241 can reflect the detection signal to the receiving part. In this way, it is possible to determine whether the clamp 42 has reached the first limit position and the second limit position by whether the receiving part of the first sensor 471 and the receiving part of the second sensor 472 receive the detection signal.

[0121] For example, such as Figure 19 (a) and Figure 19 As shown in (b), Figure 19 (a) and Figure 19 (b) is a schematic diagram showing the cooperation of a first sensor 471 and a second sensor 472 with a positioning member 424. The positioning member 424 is shaded to indicate the portion that reflects the detection signal. The left side shows the second sensor 472 corresponding to the second extreme position, and the right side shows the first sensor 471 corresponding to the first extreme position. Figure 19 As shown in (a), when the receiving part of the second sensor 472 receives the reflected detection signal, and the receiving part of the first sensor 471 does not receive the reflected detection signal, it indicates that the clamp 42 has reached the second limit position; Figure 19 As shown in (b), when the receiving part of the second sensor 472 does not receive the reflected detection signal, and the receiving part of the first sensor 471 receives the reflected detection signal, it indicates that the clamping plate 42 has reached the first limit position. Of course, there are other strategies for determining whether the clamping plate 42 has reached the first and second limit positions, which will not be listed here.

[0122] Please see Figure 14 and Figure 20In some embodiments, the delivery device 40 may further include a motion drive structure 46, which is at least partially mounted on the clamping plate 42 and is used to drive a motion structure on the clamping plate 42 to move relative to the clamping plate 42 along a third direction (Y1 / Y2), which intersects with the second direction (X1 / X2). Thus, when the goods 5 are carried on the motion structure, even if the clamping plate 42 remains stationary in the third direction (Y1 / Y2), the goods 5 can still be moved along the third direction (Y1 / Y2) by driving the motion structure. Compared to driving the entire clamping plate 42 to move in the third direction (Y1 / Y2), this reduces the power consumption of the delivery device 40 while ensuring the normal transportation of the goods 5.

[0123] Each clamp 42 is provided with a movable structure; for details, please refer to [link / reference]. Figure 20 In some embodiments, the moving structure includes a first moving structure 44 and a second moving structure 45. The first moving structure 44 is connected to the clamping plate 42, and the second moving structure 45 is connected to the first moving structure 44 and is used to carry the goods 5. A moving drive structure 46 is connected to the first moving structure 44 and is used to drive the first moving structure 44 to move relative to the clamping plate 42 in a third direction (Y1 / Y2) in a primary direction. When the first moving structure 44 moves in the third direction (Y1 / Y2), the moving drive structure 46 is also used to drive the second moving structure 45 to move relative to the first moving structure 44 in a third direction (Y1 / Y2) in a secondary direction.

[0124] It should be noted that, please refer to Figure 26 The delivery device 40 is used to deliver the contents stored in the vending machine 1A (e.g., Figure 1The goods 5 shown are transported to the loading port 713 for consumers to pick up from the collection port 715. The loading port 713 is usually small in size, making it difficult for general pick-up and delivery devices to reach in, resulting in inaccurate placement and misplacement of goods 5. In addition, the first moving structure 44 is provided on the clamping plate 42 and is capable of moving relative to the clamping plate 42 in a third direction (Y1 / Y2). The maximum travel of the first moving structure 44 relative to the clamping plate 42 in the third direction (Y1 / Y2) is equal to the length of the clamping plate 42 in the third direction (Y1 / Y2). In this embodiment, the first moving structure 44 moves relative to the clamping plate 42 in a third direction (Y1 / Y2) for a primary movement. Furthermore, while the first moving structure 44 moves in the third direction (Y1 / Y2), it can also drive the second moving structure 45 to move relative to the first moving structure 44 in the third direction (Y1 / Y2) for a secondary movement. It can be understood that the maximum movement distance of the first moving structure 44 relative to the clamping plate 42 in the third direction (Y1 / Y2) is the sum of the length of the clamping plate 42 in the third direction (Y1 / Y2) and at least a portion of the length of the first moving structure 44 in the third direction (Y1 / Y2). That is, since this embodiment employs two-stage movement, it can increase the movable distance of the goods 5 in the third direction (Y1 / Y2) while keeping the length of the clamping plate 42 in the third direction (Y1 / Y2) constant. This facilitates insertion into the loading port 713, enabling the goods 5 to be placed in the correct position smoothly, avoiding waste and loss due to improper placement of the goods 5, such as the goods 5 being stuck or falling.

[0125] Please see Figure 14 , Figure 20 and Figure 21 In some embodiments, the moving drive structure 46 may include a moving drive member 461, a first transmission assembly 462, and a second transmission assembly 463. The first transmission assembly 462 is connected to the moving drive member 461 and the first moving structure 44, and the moving drive member 461 drives the first moving structure 44 to move along a third direction (Y1 / Y2) through the first transmission assembly 462. The second transmission assembly 463 is connected to the first moving structure 44 and the second moving structure 45, and the moving drive member 461 drives the second moving structure 45 to move along a third direction (Y1 / Y2) through the first transmission assembly 462 and the second transmission assembly 463.

[0126] In some embodiments, the movable drive member 461 is fixedly connected to the base 41 via a second support 418 and is housed within the receiving cavity 416. The first transmission assembly 462 is connected to the movable drive member 461 and the first movable structure 44 and is also housed within the receiving cavity 416. The movable drive member 461 drives the first transmission assembly 462 to move the first movable structure 44 relative to the clamping plate 42 along a third direction (Y1 / Y2). Since both the movable drive member 461 and the first transmission assembly 462 are housed within the receiving cavity 416, both are protected, thereby extending the service life of the delivery device 40.

[0127] Specifically, in some embodiments, the first transmission assembly 462 may include a transmission component 4621, a guide screw 4622, and a moving block 4623. The transmission component 4621 is connected to the moving drive component 461, and the guide screw 4622 is connected to the moving drive component 461 via the transmission component 4621. The moving block 4623 is sleeved on the guide screw 4622 and connected to the first moving structure 44. When the moving drive component 461 drives the transmission component 4621 to move and rotate the guide screw 4622, the moving block 4623 moves along the guide screw 4622, thereby causing the first moving structure 44 to move along a third direction (Y1 / Y2).

[0128] like Figure 14 As shown, in some embodiments, the guide screw 4622 extends in a third direction (Y1 / Y2). One end of the guide screw 4622 is rotatably fixed to the third sidewall 414, and the other end is connected to the transmission component 4621 and rotatably connected to the fourth sidewall 415. The moving block 4623 is sleeved on the guide screw 4622, and its two ends are respectively connected to two first moving structures 44. The transmission component 4621 is connected to the moving drive component 461. When the moving drive component 461 drives the transmission component 4621 to move, the guide screw 4622 connected to the transmission component 4621 can rotate, and the moving block 4623 sleeved on the guide screw 4622 can engage with the thread on the guide screw 4622, thereby driving the two first moving structures 44 to move along the extension direction of the guide screw 4622, that is, driving the two first moving structures 44 to move along a third direction (Y1 / Y2). In this way, the first moving structures 44 move relative to the clamping plate 42 along the third direction (Y1 / Y2). The third direction (Y1 / Y2) intersects with the second direction (X1 / X2). In some embodiments, the third direction (Y1 / Y2) may or may not be perpendicular to the second direction (X1 / X2), and there is no limitation here.

[0129] Further, please refer to Figure 20The transmission component 4621 may include a drive wheel 46211, a transmission wheel 46212, and a belt 46213. The drive wheel 46211 is connected to the output shaft of the moving drive component 461, and the transmission wheel 46212 is sleeved on the guide screw 4622. The drive wheel 46211 and the transmission wheel 46212 are located at both ends of the belt 46213, and the belt 46213 is wound around the drive wheel 46211 and the transmission wheel 46212. When the output shaft of the moving drive component 461 rotates, the drive wheel 46211 connected to the output shaft can rotate with the output shaft, so that the belt 46213 wound on it drives the transmission wheel 46212 to rotate with the drive wheel 46211, thereby driving the guide screw 4622 passing through the transmission wheel 46212 to rotate together, so that the moving block 4623 sleeved on the guide screw 4622 moves along a third direction (Y1 / Y2).

[0130] Of course, in some embodiments, the transmission component 4621 may be omitted, and one end of the guide screw 4622 may be directly connected to the output shaft of the moving drive component 461, that is, the moving drive component 461 directly drives the guide screw 4622 to rotate. Furthermore, the transmission component 4621 may also employ other structures. For example, in some embodiments, the transmission component 4621 includes a meshing first gear and a second gear. The first gear is connected to the output shaft of the moving drive component 461, and the second gear is sleeved on the guide screw 4622. Thus, during the rotation of the output shaft of the moving drive component 461, the guide screw 4622 can also be driven to rotate via the first and second gears.

[0131] Please continue reading. Figure 20 In some embodiments, the first plate 421 of the clamping plate 42 may be provided with a first track 425 extending along a third direction (Y1 / Y2). The first moving structure 44 may include a connecting rod 441, a connecting plate 442, and a moving plate 443. The connecting plate 442 is provided with a connecting part 4421 and a mating part 4422. The connecting part 4421 is connected to the moving block 4623 through the connecting rod 441 and can move along the third direction (Y1 / Y2) with the moving block 4623. The moving plate 443 is fixedly connected to the connecting plate 442. The second moving structure 45 is movably mounted on the moving plate 443. The mating part 4422 cooperates with the first track 425 to drive the moving plate 443 to move along the third direction (Y1 / Y2). Since the first track 425 is provided on the clamping plate 42, the mating part 4422 of the first moving structure 44 is mated with the first track 425, so the first track 425 has a guiding function, which is conducive to the stable movement of the moving plate 443 of the first moving structure 44 along the third direction (Y1 / Y2).

[0132] Specifically, the connecting plate 442 has a first layer 4423 and a second layer 4424 fixedly connected. One end of the connecting rod 441 is fixed to the moving block 4623, and the other end passes through the first layer 4423 and the second layer 4424 of the connecting plate 442. Both the first layer 4423 and the second layer 4424 of the connecting plate 442 can move along the connecting rod 441. Thus, when the clamping plate 42 moves along the second direction (X1 / X2), the connecting plate 442 can also move along the connecting rod 441 along the second direction (X1 / X2). The end of the first layer 4423 of the connecting plate 442 away from the connecting rod 441 is fixedly connected to the moving plate 443, and the mating part 4422 is provided at the end of the second layer 4424 away from the connecting rod 441. In this way, the connecting plate 442 can simultaneously connect to the moving plate 443 and mate with the first track 425.

[0133] Please see Figure 20 and Figure 21 In some embodiments, the movable plate 443 may include a first sub-plate 4431 and a mounting plate 4432. The first sub-plate 4431 is connected to the connecting plate 442, and the mounting plate 4432 is connected to the first sub-plate 4431. The second transmission assembly 463 includes a rack 4631, a gear 4632, a driven wheel 4633, and a conveyor belt 4634. The rack 4631 is fixedly mounted on the clamping plate 42, and the gear 4632 is rotatably mounted on the mounting plate 4432 via a connecting shaft and engages with the rack 4631. The driven wheel 4633 rotates following the rotation of the gear 4632. The conveyor belt 4634 is sleeved on the driven wheel 4633, and the second movable structure 45 is fixedly connected to the conveyor belt 4634.

[0134] It should be noted that gear 4632 and rack 4631 mesh with each other. When gear 4632 moves relative to rack 4631, rack 4631 can cause gear 4632 to rotate. During the process of moving drive 461 driving first moving structure 44 to move relative to clamp 42 in a third direction (Y1 / Y2), moving plate 443 can move relative to clamp 42 in a third direction (Y1 / Y2), which can cause gear 4632 on moving plate 443 to move relative to rack 4631 on clamp 42, that is, to rotate gear 4632. When gear 4632 rotates, driven wheel 4633 connected to it can rotate together with gear 4632, so that conveyor belt 4634 sleeved on driven wheel 4633 moves, and drives second moving structure 45 fixedly connected to conveyor belt 4634 to move relative to first moving structure 44 in a third direction (Y1 / Y2), thus realizing the second-level movement of second moving structure 45.

[0135] Furthermore, in some implementations, please refer to... Figure 22The movable plate 443 may further include a second sub-plate 4433 disposed opposite to the first sub-plate 4431. The driven wheel 4633 includes a first driven wheel 46331, a second driven wheel 46332, a third driven wheel 46333, and a fourth driven wheel 46334. The conveyor belt 4634 includes a first conveyor belt 46341 and a second conveyor belt 46342. The first driven wheel 46331 is mounted on a connecting shaft and coaxial with the gear 4632; the second driven wheel 46332 and the third driven wheel 46333 are coaxially connected and respectively mounted on the first sub-plate 4431 and the second sub-plate 4433; and the fourth driven wheel 46334 is mounted on the first sub-plate 4431. The first conveyor belt 46341 is fitted onto the first driven wheel 46331 and the second driven wheel 46332, the second conveyor belt 46342 is fitted onto the third driven wheel 46333 and the fourth driven wheel 46334, and the second conveyor belt 46342 is fixedly connected to the second moving structure 45.

[0136] When gear 4632 rotates, the first driven wheel 46331, which is coaxial with it, can rotate accordingly. The rotation of the first driven wheel 46331 can drive the first conveyor belt 46341, which is sleeved on it, to rotate the second driven wheel 46332, which is sleeved on the first conveyor belt 46341. The rotation of the second driven wheel 46332 can drive the third driven wheel 46333, which is coaxially connected with it, to rotate. The rotation of the third driven wheel 46333 can drive the second conveyor belt 46342, which is sleeved on it, to rotate the fourth driven wheel 46334, which is sleeved on the second conveyor belt 46342, and to drive the second moving structure 45, which is fixedly connected to the second conveyor belt 46342, to move relative to the first moving structure 44 in a third direction (Y1 / Y2). Thus, the second-level movement of the second moving structure 45 is realized.

[0137] In some embodiments, the movable plate 443 may further include a third sub-plate 4434, which connects to the first sub-plate 4431 and the second sub-plate 4433. The first sub-plate 4431, the second sub-plate 4433, and the third sub-plate 4434 form a receiving cavity 4436, in which the driven wheel 4633 and the conveyor belt 4634 are both received. The third sub-plate 4434 has an opening 4437, through which the second movable structure 45, supported on the first sub-plate 4431, extends into the receiving cavity 4436 and is fixedly connected to the second conveyor belt 46342. Since the driven wheel 4633 and the conveyor belt 4634 are both received in the receiving cavity 4436, this helps to protect the driven wheel 4633 and the conveyor belt 4634 from easy damage, thereby extending the service life of the second transmission assembly 463 and thus extending the service life of the delivery device 40.

[0138] It should be noted that in some embodiments, the first track 425 on the clamping plate 42 corresponds to the receiving cavity 4436. In this case, the length of the second layer 4424 of the connecting plate 442 is greater than the length of the first layer 4423. Since the first track 425 corresponds to the receiving cavity 4436, the moving plate 443 can also protect the first track 425 and prevent it from being damaged.

[0139] Please continue reading. Figure 20 and Figure 21 The first moving structure 44 may further include a second track 444, and the moving plate 443 may further include a fourth sub-plate 4435. One end of the fourth sub-plate 4435 is connected to the first sub-plate 4431, and the other end is connected to the connecting plate 442, that is, the other end is connected to the first layer 4423 of the connecting plate 442. The fourth sub-plate 4435 and the second sub-plate 4433 are located on opposite sides of the first sub-plate 4431, and the second track 444 is disposed on the fourth sub-plate 4435, and the second moving structure 45 slides in conjunction with the second track 444. Thus, when the second conveyor belt 46342 moves, driving the second moving structure 45 to move relative to the first moving structure 44 along a third direction (Y1 / Y2), part of the structure of the second moving structure 45 can slide on the second track 444, so the second track 444 has a guiding function, thereby facilitating the stable movement of the second moving structure 45 along the third direction (Y1 / Y2).

[0140] Specifically, please refer to Figure 21 In some embodiments, the second moving structure 45 may include a carrier 451, a slider 452, and a connector 453. The carrier 451 is slidably supported on the first sub-plate 4431 of the moving plate 443 and is used to support the cargo 5. The slider 452 is connected to one end of the carrier 451 and slides in cooperation with the second track 444. The connector 453 is connected to the other end of the carrier 451 and extends into the receiving cavity 4436 through the opening 4437 of the third sub-plate 4434, and is fixedly connected to the conveyor belt 4634. When the first moving structure 44 moves relative to the clamping plate 42 in a third direction (Y1 / Y2), the conveyor belt 4634 of the second transmission assembly 463 is driven to move, thereby moving the connector 453 fixedly connected to the conveyor belt 4634, thereby moving the carrier 451 supported on the first sub-plate 4431 in a third direction (Y1 / Y2), and causing the slider 452 to slide on the second track 444.

[0141] Please see Figure 14In some embodiments, the delivery device 40 may further include a first detector 481. The first detector 481 is disposed on the bottom wall 411 of the base 41 and located inside the base 41, that is, the first detector 481 is located within the receiving cavity 416. The first detector 481 cooperates with the moving block 4623 or the connecting rod 441 of the first moving structure 44 to detect the position of the first moving structure 44. For example, in some embodiments, the first detector 481 may cooperate with the moving block 4623 to detect the position of the first moving structure 44; or, in some embodiments, the first detector 481 may also cooperate with the connecting rod 441 to detect the position of the first moving structure 44.

[0142] The following explanation uses the example of the first detector 481 cooperating with the moving block 4623 to detect the position of the first moving structure 44. Please refer to [link / reference]. Figure 14 In some embodiments, the moving drive 461 is a stepper motor, and the first detector 481 is disposed on the bottom wall 411 of the base 41 and is located in the initial position. The first detector 481 is used to sense the moving block 4623. When the first detector 481 senses the moving block 4623, it indicates that the moving block 4623 is at the initial position, that is, the first moving structure 44 is at the position corresponding to the initial position. Subsequently, the moving drive 461 drives the first moving structure 44 to move along a third direction (Y1 / Y2). The current position of the first moving structure 44 can be obtained by the step size and movement time of the moving drive 461. This allows for obtaining the real-time position of the first moving structure 44, which is beneficial for more accurate picking, placing, and transporting of goods 5.

[0143] It should be noted that the specific implementation of the first detector 481 cooperating with the connecting rod 441 to detect the position of the first moving structure 44 is the same as the specific implementation in the above embodiment where the first detector 481 cooperates with the moving block 4623 to detect the position of the first moving structure 44, and will not be repeated here. When the first detector 481 cooperates with the connecting rod 441 to detect the position of the first moving structure 44, the delivery device 40 may include two first detectors 481, and the two first detectors 481 respectively cooperate with the two connecting rods 441 on the first moving block 4623 to detect the positions of the two first moving structures 44 respectively. Of course, the number of first detectors 481 can also be one, cooperating with one of the two connecting rods 441, and there is no limitation here.

[0144] Please see Figure 14In some embodiments, the delivery device 40 may further include a second detector 483. The second detector 483 is disposed on the bottom wall 411 of the base 41 and protrudes between two clamping plates 42. The second detector 483 is used to detect the quantity of goods 5. For example, in some embodiments, the second detector 483 may be a distance sensor. The second detector 483 is used to emit a detection signal toward the second moving structure 45 carrying the goods 5, and the detection signal is reflected back to the second detector 483 after reaching the goods 5. The second detector 483 can obtain the distance from the second detector 483 to the goods 5 based on the time difference between sending and receiving the detection signal and the transmission speed of the detection signal in the air, and then determine the quantity of goods 5 carried on the second moving structure 45 based on the detected distance. In some embodiments, a larger detected distance indicates a smaller quantity of goods 5 carried on the second moving structure 45.

[0145] Of course, in some embodiments, the second detector 483 can also be a weight sensor, which determines the quantity of goods 5 by detecting the weight of goods 5, and there is no limitation here.

[0146] Please see Figure 23 and Figure 24 The heating device 50 includes a heating chamber 51 and a heater 53. The heating chamber 51 is used to place goods 5 ( Figure 6 As shown, heater 53 is used to heat the goods 5 inside heating chamber 51. Specifically, heating chamber 51 is formed inside heating chamber 511, and heater 53 is disposed inside heating chamber 51 to heat the food inside heating chamber 511. Among them, heater 53 can be microwave heater, resistance wire heater, gas stove, etc., and is not limited here.

[0147] Supply cabinet 2 may also include an axial fan 61. Please refer to... Figure 5 The supply cabinet 20 includes a first side wall 23 opposite to the receiving side wall 22, a second side wall 24 connecting the receiving side wall 22 and the first side wall 23, and a top wall 25 connecting the receiving side wall 22, the first side wall 23 and the second side wall 24. The first side wall 23 is provided with a first air outlet 231.

[0148] The axial fan 61 is located inside the supply cabinet 20 and installed at the first air outlet 231. The axial fan 61 is used to absorb the hot air generated by the heater 53 heating the goods 5 and exhaust the hot air from the first air outlet 231.

[0149] In some embodiments, the heating device 50 includes a plurality of heaters 53 corresponding to each heating chamber 51. The plurality of heaters 53 are used together to heat the goods 5 in the corresponding heating chamber 51. Each heater 53 corresponds to an axial fan 61, and each axial fan 61 dissipates heat from the corresponding heater 53 to improve heat dissipation efficiency.

[0150] In some embodiments, the heating device 50 includes two heaters 53 corresponding to the heating chamber 51, with the two heaters 53 respectively disposed on opposite sides of the heating chamber 51. The two heaters 53 can heat the goods 5 simultaneously, improving heating efficiency. Simultaneously, the two heaters 53 being disposed on opposite sides of the heating chamber 51 ensures that the goods 5 are heated evenly, guaranteeing their taste.

[0151] Please refer to the following: Figure 1 , Figure 5 , Figure 23 and Figure 24 In some embodiments, the top wall 25 is provided with an air inlet 251, which is opposite to the heating device 50 and is used to allow air from outside the supply cabinet 20 to enter the interior of the supply cabinet 20 to form convection with the first air outlet 231. The temperature of the outside airflow is lower than that of the airflow inside the supply cabinet 20. When the axial fan 61 is working, the cold air from outside enters the interior of the supply cabinet 20 through the air inlet 251, flows through the heater 53, and is discharged from the first air outlet 231 (e.g., Figure 5 (As shown by the solid arrow in the middle), thereby improving the heat dissipation efficiency of the axial fan 61 in cooling the heating device 50.

[0152] Please see Figure 5 In some embodiments, a gap 230 is provided between the upper surface of the first sidewall 23 and the lower surface of the top wall 25. This gap 230 allows external air to enter the supply cabinet 20, creating convection with the first air outlet 231. When the axial fan 61 operates, external cold air can enter the supply cabinet 20 through the gap 230, flow through the heater 53, and then be discharged from the first air outlet 231 (e.g., ...). Figure 5 (As shown by the dashed arrow in the middle), this also improves the heat dissipation efficiency of the axial fan 61 in cooling the heating device 50.

[0153] Please continue reading. Figure 5 In some embodiments, the second sidewall 24 may be provided with a second air outlet 241, which is used for hot air to flow out to the outside of the supply cabinet 20, so as to improve the heat dissipation efficiency of the heating device 50.

[0154] Please combine Figure 2In some embodiments, the supply cabinet 2 may further include a decorative panel 63, which is installed on the first side wall 23 and blocks the first air outlet 231. A gap 630 is provided between the decorative panel 63 and the first side wall 23 to connect the first air outlet 231 with the outside of the supply cabinet 2, allowing the hot air discharged through the first air outlet 231 to dissipate to the outside. The decorative panel 63 may be tempered glass to improve rigidity, or it may be made of hard plastic. Any pattern may be painted on the decorative panel 63, or various posters or promotional pictures may be drawn on it to enhance its aesthetics.

[0155] In some embodiments, the top wall 25 protrudes relative to the first side wall 23; the supply cabinet 2 may also include a lighting lamp 65, which is mounted on the protruding portion of the top wall 25 for illumination, making it convenient for users to use at night.

[0156] Please see Figure 25 In some embodiments, the supply cabinet 20 may further include a smoke exhaust device 80 for exhausting the fumes generated by the heating device 50. For example... Figure 23 As shown, in some embodiments, the heating device 50 is disposed above the insulated compartment 70, for example, the heating device 50 is disposed at the top of the supply cabinet 20, and the insulated compartment 70 is located at the bottom of the supply cabinet 20, so that the smoke exhaust device 80 can exhaust the fumes from the top of the supply cabinet 20. Specifically, the smoke exhaust device 80 is disposed at the top of the supply cabinet 20 and avoids the movement path of the delivery device 40 to avoid interfering with the movement of the delivery device 40.

[0157] Specifically, the smoke exhaust device 80 may include a smoke inlet duct 81, a fan (not shown), and a smoke exhaust duct 82. The smoke inlet duct 81 is used to communicate with the heating chamber 511. The fan is installed inside the smoke inlet duct 81 and is used to draw the oil fumes from the heating device 50 into the smoke inlet duct 81. The smoke exhaust duct 82 is connected to the smoke inlet duct 81 and is used to exhaust the oil fumes.

[0158] More specifically, the smoke inlet duct 81 is located at the top of the supply cabinet 20 and is arranged around the path of the delivery device 40 to avoid interfering with the movement of the delivery device 40. For example, the smoke inlet duct 81 is located inside the supply cabinet 20 and extends horizontally, winding around the path of the delivery device 40 so that the delivery device 40 will not collide with the smoke inlet duct 81 when it moves in the first direction (Z1 / Z2), the second direction (X / X), or the third direction (Y / Y).

[0159] Please see Figure 25 In some embodiments, the exhaust duct 82 extends along a first direction (Z1 / Z2) and extends from the top of the supply cabinet 20 to exhaust the fumes outside the supply cabinet 20.

[0160] Please see Figure 25In some embodiments, the smoke inlet duct 81 includes a smoke inlet section 811, a connecting section 812, and a receiving section 813 connecting the smoke inlet section 811 and the connecting section 812. The smoke inlet section 811 communicates with the heating chamber 511 of the heating device 50, the connecting section 812 communicates with the smoke exhaust duct 82, and the receiving section 813 is used to house the fan. In some embodiments, the smoke exhaust duct 82, the connecting section 812, and the receiving section 813 are located on the opposite side of the heating device 50, and the smoke inlet section 811 connects the receiving section 813 and the heating chamber 511 along a third direction (Y1 / Y2), so that the smoke inlet duct 81 and the smoke exhaust duct 82 are arranged around the movement path of the delivery device 40 at the top of the supply cabinet 20.

[0161] In some embodiments, the inner diameter of the receiving section 813 is larger than the inner diameter of the smoke inlet section 811. This increases the negative pressure in the receiving section 813, facilitating the drawing of fumes into the smoke inlet duct 81. In some embodiments, the fan includes a centrifugal fan to improve the suction capacity of the smoke exhaust device 80 and increase the smoke exhaust flow rate.

[0162] In some embodiments, the smoke exhaust device 80 may further include a filter chamber 83 and a filter (not shown). The filter chamber 83 connects the smoke inlet pipe 81 and the smoke exhaust pipe 82. The filter is disposed within the filter chamber 83 and is used to filter oil fumes. In one embodiment, the filter includes filter cotton for absorbing the odor of the oil fumes, allowing the smoke exhaust pipe 82 to discharge the deodorized gas. This avoids the presence of strong oil fume odors near the vending machine 1A, which could negatively impact the user experience.

[0163] Please see Figure 23 , Figure 24 and Figure 26 In some embodiments, the insulated compartment 70 includes a compartment 71, a loading door 72, and a discharging door 73. The compartment 71 has a receiving space 711, a loading port 713 communicating with the receiving space 711, and a discharging port 715. The receiving space 711 is used to store goods 5 and insulated goods 5. The loading door 72 is rotatably installed in the compartment 71 and can cover the loading port 713. The first moving structure 44 and / or the second moving structure 45 of the delivery device 40 can push the loading door 72 to rotate and extend into the receiving space 711, and deliver the goods 5 held by the second moving structure 45 into the compartment 71.

[0164] In some embodiments, there may be multiple compartments 71, which are distributed along a first direction (Z1 / Z2) and a second direction (X1 / X2). The delivery device 40 is able to carry goods 5 and move along the first direction (Z1 / Z2) and / or the second direction (X1 / X2) to deliver the goods 5 into the corresponding compartments 71.

[0165] In some embodiments, the loading door 72 is rotatably connected to the compartment 71 via connecting parts such as hinges, pivots, torsion springs, and chain hinges. For example, the loading door 72 is mounted on the upper end of the loading opening 713 via a hinge (not shown). Thus, without external force pushing the loading door 72 to rotate, the loading door 72 closes the loading opening 713 under its own weight.

[0166] In some embodiments, the hinge includes an automatic spring-back hinge for automatically closing the loading opening 713 of the loading door 72. Without external force pushing the loading door 72 to flip, the loading door 72 closes the loading opening 713 due to the spring-back action of the automatic spring-back hinge. Thus, the loading door 72 is not limited to being located above the loading opening 713, but can also be located at the lower, left, or right end of the loading opening 713.

[0167] Please combine Figure 1 In some embodiments, the food sold by vending machine 1A is packaged in food containers. Multiple (packaged) food items can be stacked along the height of compartment 71, and delivery device 40 can repeatedly clamp and release multiple food items to be stacked in the same compartment 71. For example, if a user purchases a meal set through vending machine 1A, the main dish, side dish, and soup in the meal set are packaged in three separate food containers. Delivery device 40 can separately deliver the food containers corresponding to the main dish, side dish, and soup to heating device 50 for heating and then deliver them to the same compartment 71, allowing the three food containers corresponding to the same meal set to be stacked in the same compartment 71, so that the user does not need to retrieve food from different compartments 71.

[0168] Please see Figure 26 In some embodiments, the insulated compartment 70 further includes an alignment unit (not shown in the figure). The alignment unit is located in the compartment 71 or the loading door 72. Please refer to... Figure 23 The delivery device 40 also includes an alignment sensor (not shown) disposed on the moving structure. The alignment sensor identifies an alignment unit to align the moving structure (first moving structure 44 and / or second moving structure 45) with the loading port 713. For example, the alignment unit is a Hall element, and the alignment sensor is a Hall sensor. A sensing signal is triggered when the Hall sensor detects a Hall element. Please refer to... Figure 14 The moving drive structure 46 drives the first moving structure 44 and / or the second moving structure 45 to extend relative to the base 41 according to the sensing signal, so as to deliver food into the compartment 71.

[0169] In some embodiments, insulation material may be provided inside the compartment 71 to give the insulated compartment 70 a better insulation effect. In some embodiments, insulation material is provided on the side of the loading door 72 and the side of the cover facing the inside of the compartment 71, which can improve the insulation effect of the compartment 71 when the loading door 72 blocks the loading opening 713.

[0170] In some embodiments, the warming compartment 70 further includes a warming element 74 disposed within the compartment 71 to maintain the temperature of the compartment 71 within a preset temperature range. The warming element 74 may include heating devices such as heating wires or heat lamps, and is not limited thereto. For example, the warming element 74 may be a heat lamp, capable of generating thermal radiation light to irradiate the food inside the compartment 71, thereby maintaining the temperature of the food and preventing it from cooling or spoiling. As another example, the warming element 74 may be a heating wire, and the warming compartment 70 may also include a partition (not shown) disposed at the bottom of the compartment 71, with the heating wire disposed below the partition for heating the partition. Food fed into the warming compartment 70 is placed above the partition and heated by the heating wire. This prevents the heating wire from directly contacting the food and scalding it.

[0171] In some embodiments, the insulated compartment 70 also includes an infrared sensor 75 disposed at the bottom of each compartment 71 for detecting whether there is food in the compartment 71, so that if there is food in the compartment 71, the vending machine 1A prompts the user to pick up the food in the corresponding compartment 71.

[0172] In some embodiments, an infrared sensor 75 at the bottom of the compartment 71 is also used to detect whether the delivery device 40 has delivered the food into the appropriate position in the compartment 71, so as to ensure that the food in the compartment 71 will not block the loading door 72 from returning to its initial position after the moving structure retracts relative to the base 41.

[0173] Please see Figure 26 In some embodiments, the dispensing slot 715 is used for users to retrieve food from the storage compartment 71. A dispensing door 73 is disposed in the storage compartment 71 and corresponds to the dispensing slot 715. When food is present in the storage compartment 71, the dispensing door 73 is locked to close the dispensing slot 715. The dispensing door 73 may be made of a transparent material, allowing users to observe the food inside the storage compartment 71, facilitating food retrieval. It also allows passersby to see the food inside the storage compartment 71, stimulating their desire to purchase.

[0174] Please see Figure 1 and Figure 23 In some embodiments, the supply cabinet 2 further includes an operation panel 26 disposed on the first side wall 23. The retrieving surface 21 of the supply cabinet body 20 is the outer side surface of the first side wall 23. Please refer to... Figure 26 The first side wall 23 has an opening 233, which corresponds to the retrieval port 715 of the insulated compartment 70. The delivery door 73 of the insulated compartment 70 covers the retrieval port 715 and the opening 233. The operation panel 26 is used for users to input purchase information. Purchase information may include order information, meal pickup information, etc., and is not limited here.

[0175] In some implementations, after the user enters order information and makes payment, the ordered food will be delivered to the insulated compartment 70. After the user enters pick-up information (e.g., a pick-up code), the corresponding delivery door 73 of the insulated compartment 70 will unlock and open the compartment 71, allowing the user to retrieve the food from the compartment 71.

[0176] In some embodiments, the operation panel 26 includes a touchscreen for displaying purchase information. Users can use the touchscreen to input purchase information. In yet another embodiment, the operation panel 26 includes a display screen showing purchase information and operation buttons for users to input purchase information.

[0177] In some embodiments, the supply cabinet 20 also includes a main control system (not shown), which is electrically connected to the operation panel 26 and the picking device 17, the conveying device 30, and the delivery device 40. The main control system is used to control the picking device 17, the conveying device 30, and the delivery device 40 to operate according to the purchase information, so as to retrieve food from the storage cabinet 11, put the food into the heating device 50 for heating, and put the food into the insulated compartment 70.

[0178] In some implementations, the main control system is also electrically connected to the insulated compartment 70. The insulated compartment 70 can report the availability of compartment 71 to the main control system, enabling the main control system to control the retrieval device 17, conveying device 30, and delivery device 40 to deliver food into the available compartment 71. After the user inputs the food retrieval information, the main control system controls the corresponding compartment 71's delivery door 73 to unlock and open the compartment 71, allowing the user to retrieve the food from inside.

[0179] In some embodiments, the supply cabinet 2 may also include a network module (not shown), which is electrically connected to the main control system for internet access. Users can remotely input purchase information via an app, mini-program, or other means on the online ordering page of vending machine 1A. The network module retrieves this remote purchase information, enabling the main control system to dispense food based on it. The prepared food is stored in a warming compartment 70, which maintains the food's temperature to prevent it from cooling or spoiling while waiting for the user to collect it. Thus, users do not need to collect their orders immediately after ordering, and there is no need to worry about the food cooling or spoiling due to delayed collection. Furthermore, users can place orders remotely in advance, allowing them to collect their food immediately from the warming compartment 70 upon arrival at vending machine 1A, avoiding long waiting times.

[0180] Please see Figure 23 In some embodiments, the supply cabinet 2 may further include a ticket printing device 91, which is electrically connected to the main control system and is used to print tickets based on purchase information. The first side wall 23 is provided with a ticket outlet 235 for ticket output.

[0181] Please see Figure 23 In some embodiments, the supply cabinet 2 further includes a tableware dispensing device 93, which is electrically connected to the main control system and is used to provide a corresponding number of tableware according to the purchase information. The first side wall 23 is provided with a tableware outlet 237 for dispensing tableware.

[0182] Please see Figure 23 In some embodiments, the supply cabinet 2 further includes a packaging bag dispensing device 95, which is electrically connected to the main control system and is used to provide packaging bags according to purchase information. The first side wall 23 is provided with a packaging bag outlet 239 for dispensing packaging bags.

[0183] Please see Figure 23 In some embodiments, the supply cabinet 2 also includes a placement table 97 located on the pick-up surface 21, where users can place their food after taking it and wait for receipts, cutlery, or packaging bags to be dispensed. In some embodiments, cutlery can be dispensed from the cutlery outlet 237 to the placement table to prevent it from falling to the ground.

[0184] In summary, the vending machine 1A provided in this application supports the storage of refrigerated or frozen food, and can heat the refrigerated or frozen food and then put it into the heat preservation chamber 70 to keep it warm, so as to prevent the food from getting cold or spoiling and ensure that the food is at a suitable temperature when the user picks up the food.
