Description

Technical Field

[0001] This application relates to the field of packaging, and more specifically, to a packaging device and a vending machine. Background Technology

[0002] Food packaging is a crucial step in the food processing industry. Currently, some vending machines can sell pre-packaged food, such as food already packaged on the production line. In some applications, vending machines can sell freshly prepared food, which cannot be pre-packaged on the production line and needs to be packaged in the vending machine. However, on-line packaging solutions require multiple large devices working together, making them unsuitable for the on-the-spot packaging of items waiting to be packaged in vending machines. Summary of the Invention

[0003] This application provides a packaging device. The packaging device includes a consumable receiving mechanism, a lifting mechanism, and a sealing and cutting mechanism. The consumable receiving mechanism is capable of receiving and releasing consumables for packaging a packaged item. The lifting mechanism is capable of moving the packaged item vertically. The sealing and cutting mechanism is capable of cutting and sealing the consumables that have been pulled out by the packaged item and / or the lifting mechanism and have completed the process of receiving the packaged item.

[0004] In some embodiments, the consumable receiving mechanism includes a consumable box; the lifting mechanism includes a connected lifting component and an adsorption component, the adsorption component being used to carry the item to be packaged and adsorb the consumable, and the lifting component being used to drive the adsorption component to lift and lower. When the lifting component drives the adsorption component to move through the consumable box and expose it, the adsorption component adsorbs the consumable and carries the item to be packaged placed inside the consumable; when the lifting component drives the adsorption component to move to drag the consumable containing the item to be packaged until the item to be packaged corresponds to the sealing and cutting mechanism, the sealing and cutting mechanism cuts and seals the consumable containing the item to be packaged.

[0005] In some embodiments, the consumable is cylindrical and includes an initial closed end and an open end opposite to the closed end. The item to be packaged can be housed in the consumable and carried on the closed end. The consumable also includes a packaging part and a part to be packaged. The packaging part corresponds to the position of the sealing and cutting mechanism and is used to package the item to be packaged. The part to be packaged is connected to the consumable box and the packaging part. The sealing and cutting mechanism is used to seal the packaging part, seal the part to be packaged to form a new closed end, and cut the packaging part and the part to be packaged.

[0006] In some embodiments, the consumable box is disposed on the lifting path of the lifting mechanism and has a through hole and a receiving slot for receiving the consumable. The adsorption assembly includes a tray and a negative pressure motor. The tray includes a support side, and the negative pressure motor is connected to the tray and used to evacuate air from the tray to generate an adsorption force on the support side. The lifting assembly is used to drive the tray to lift and lower. When the lifting assembly drives the tray to move into the through hole, the negative pressure motor evacuates air, causing the adsorption force generated on the support side to adsorb the consumable; when the lifting assembly drives the tray away from the through hole, the adsorption force drags the consumable out of the receiving slot.

[0007] In some embodiments, the tray further includes an installation side opposite to the bearing side; the bearing side is provided with a plurality of suction holes, the tray is provided with an air passage, the negative pressure motor is installed on the installation side and communicates with the suction holes through the air passage, and the lifting assembly is connected to the installation side.

[0008] In some embodiments, the lifting assembly includes a base and a lifting member. The lifting member is mounted on the base and includes a body and a telescopic rod that can extend and retract relative to the body, the end of the telescopic rod being fixedly connected to the tray.

[0009] In some embodiments, the lifting assembly further includes a position detector. The position detector is mounted on the base, and a portion of its structure is capable of rising and falling with the extension and retraction of the telescopic rod, and is used to detect the distance of the tray relative to the base.

[0010] In some embodiments, the position detector includes a draw-wire displacement sensor, the body of which is mounted on the base, and the draw-wire of which extends from the body and is connected to the mounting side of the tray.

[0011] In some embodiments, the position detector includes a transmitter and a receiver, one of which is mounted on the base and the other on the mounting side of the tray. The transmitter transmits a detection signal, and the receiver receives the detection signal transmitted by the transmitter.

[0012] In some embodiments, the adsorption assembly further includes a pressure detector. The pressure detector is disposed on the bearing side of the tray and is used to detect the pressure of the object carried by the tray; the lifting assembly is used to initiate lifting based on the detected pressure and stop at a predetermined height based on the detected distance.

[0013] In some embodiments, when the lifting assembly drives the tray to rise so that the tray passes through the through hole and is exposed, and the tray carries the package to be packaged, the pressure detector of the adsorption assembly feeds back a signal of receiving the package to be packaged to the lifting assembly, and the lifting assembly drives the tray to descend according to the signal of receiving the package to be packaged.

[0014] In some embodiments, when the lifting assembly drives the tray down and the distance detected by the position detector of the adsorption assembly indicates that the tray has descended by the height of one package, the lifting assembly stops driving the tray down. When the lifting assembly drives the tray down and the distance detected by the position detector of the adsorption assembly indicates that the tray corresponds to the sealing and cutting mechanism, the lifting assembly stops driving the tray down.

[0015] In some embodiments, the sealing and cutting mechanism includes a first plate, a second plate, and a driving assembly. The first plate includes a first body, a first heat-sealing element, and a first cutting element, the first heat-sealing element and the first cutting element being disposed on the first body.

The driving assembly is used to drive the first plate and the second plate to move away from or towards each other. When the first plate and the second plate are close to each other, the first heat-sealing element and the second body can jointly seal the edge of the packaged portion located between the first plate and the second plate, and the first cutting element is used to cut off the sealed packaged portion.

[0016] In some embodiments, the first plate further includes a second heat-sealing member disposed on the first body. The second heat-sealing member is located on the side of the first heat-sealing member opposite to the first cutting member and is spaced apart from the first heat-sealing member. The first heat-sealing member, the second heat-sealing member, and the second body can jointly seal the packaging portion located between the first plate and the second plate to form a sealed edge portion.

[0050] Please see Figure 1 This application provides a vending machine 1000. The vending machine 1000 includes a packaging device 100, a housing 300, and a conveying structure 500.

[0051] The outer casing 300 houses the packaging device 100. In other words, the packaging device 100 can be disposed inside the outer casing 300 to form a vending machine 1000, used for packaging items 81 (such as...) that enter the vending machine 1000. Figure 7(As shown) for packaging. In other embodiments, the packaging device 100 may be used independently of the vending machine, for example, for packaging items 81 to be packaged for other devices, without limitation.

[0052] Please see Figure 2 In some embodiments, the packaging device 100 may include a consumable receiving mechanism 20, a lifting mechanism 30, and a sealing and cutting mechanism 40. (Please refer to...) Figures 5 to 7 The consumable receiving mechanism 20 can receive and release consumables 27 for packaging the package 81. The lifting mechanism 30 can move the package 81 up and down. The sealing and cutting mechanism 40 can cut and seal the consumables 27 that are pulled out by the package 81 and / or the lifting mechanism 30 and used to receive the package 81.

[0053] Please see Figure 6 and Figure 7 The package 81 to be packaged and the consumable 27 used to package the package 81 together constitute the package 80. For example, the package 81 to be packaged is a food container, and the food container enclosed by the consumable 27 and the consumable 27 used to enclose the food container together constitute the package 80 for easy carrying by the user. Of course, the package 81 to be packaged can also be a cup, a book, or clothing, etc., and there are no restrictions here.

[0054] Please see Figure 2 and Figure 3 In some embodiments, the packaging device 100 may also include a housing 90, within which the consumable receiving mechanism 20, the lifting mechanism 30, and the sealing and cutting mechanism 40 are enclosed.

[0055] Please combine Figure 3 In one embodiment, the housing 90 is provided with a discharge port 93. The packaged item 80 is conveyed to the discharge port 93 by the lifting mechanism 30 for the user to take out.

[0056] In summary, the vending machine 1000 and the packaging device 100 of this application embodiment can package the package 81 in a timely manner. The steps of sealing the package 81 with consumable 27 and cutting the consumable 27 containing the package 81 are both performed by the packaging device 100, which can conveniently package without relying on a packaging production line.

[0057] The packaging device 100 will be further described below with reference to the accompanying drawings.

[0058] Please see Figure 2 and Figure 4 The packaging device 100 also includes a frame 10, a consumable receiving mechanism 20, a lifting mechanism 30, and a sealing and cutting mechanism 40, all housed within the frame 10. The frame 10 includes side walls 11 and a top wall 12. Figure 2In the example shown, the sidewall 11 is a long, openwork structure. In other embodiments, the sidewall 11 may also be a long, sealed plate-like structure; this is not a limitation. A bearing housing assembly (101 / 102) is provided on each opposite side of the sidewall 11. When the packaging device 100 is installed or in normal use, the top wall 12 is located at the top. Please refer to... Figure 3 In some embodiments, the frame 10 is enclosed within the housing 90. (Please refer to...) Figure 1 In another embodiment, the packaging device 100 may also exclude the housing 90, with the frame 10 enclosed by the outer shell 300.

[0059] Please see Figure 5 In some embodiments, the consumable receiving mechanism 20 includes a consumable box 21. The consumable box 21 is used to receive consumables 27.

[0060] Please combine Figure 7 In some embodiments, the consumable box 21 includes a first surface 211 and a second surface 213 facing away from each other, and a through hole 215 penetrating the first surface 211 and the second surface 213. The item to be packaged 81 can pass through the through hole 215 to be wrapped by the consumable 27.

[0061] In some embodiments, the consumable receiving mechanism 20 further includes a fixing unit 23 disposed on the consumable box 21. The fixing unit 23 is disposed on the first surface 211 or the second surface 213 and is used to fix the consumable 27 to the consumable box 21. In one embodiment, the second surface 213 of the consumable box 21 is provided with a receiving groove 2130, the fixing unit 23 is disposed in the receiving groove 2130, and the consumable 27 partially extends into the receiving groove 2130 to connect to the fixing unit 23 and block the through hole 215.

[0062] Please see Figure 4 and Figure 5 In some embodiments, the lifting mechanism 30 includes a lifting assembly 31 and an adsorption assembly 33 connected together. The adsorption assembly 33 is used to carry the packaged item 81 and to adsorb the consumable 27 so that the consumable 27 can be pulled out of the consumable box 21. The lifting assembly 31 is used to drive the adsorption assembly 33 to move up and down.

[0063] In some embodiments, the adsorption component 33 is also used to adsorb the packaged item 81 to prevent the packaged item 81, which is carried on the lifting mechanism 30, from falling off the lifting mechanism 30.

[0064] In some embodiments, the lifting mechanism 30 is located below the consumable box 21. Thus, even if the lifting mechanism 30 does not adsorb the consumable 27, when the lifting mechanism 30 carries the packaged item 81 and moves up and down, the consumable 27 will be pressed against the lifting mechanism 30 and move along with it. In other embodiments, the lifting mechanism 30 may also be located above the consumable box 21; this is not a limitation. In this case, the adsorption component 33 is used to adsorb the consumable 27 and the packaged item 81, thereby moving the consumable 27 and / or the packaged item 81 and preventing the packaged item 81 from falling off the lifting mechanism 30.

[0065] Please see Figure 4 and Figure 5 In some embodiments, the fixing unit 23 is disposed on the second surface 213. The lifting mechanism 30 is located on the side where the second surface 213 of the consumable box 21 is located. When it is necessary to pack the item 81 to be packaged, the lifting assembly 31 drives the adsorption assembly 33 to move through the through hole 215 of the consumable box 21 and protrude from the through hole 215 to await the loading of the item 81 to be packaged into the packaging device 100; in this case, the consumable 27 is adsorbed by the adsorption assembly 33 and moves together with the lifting mechanism 30 to the side where the first surface 211 of the consumable box 21 is located. After the item 81 to be packaged is placed on the lifting mechanism 30, the item 81 to be packaged is pressed on top of the consumable 27, and the lifting mechanism 30 drives the item 81 to pass through the through hole 215 from the side where the first surface 211 of the consumable box 21 is located to the side where the second surface 213 of the consumable box 21 is located, so that the bottom and sides of the item 81 to be packaged are wrapped by the consumable 27. Please refer to Figure 6 and Figure 7 The sealing and cutting mechanism 40 can cut the consumable 27 containing the packaged item 81 from the consumable box 21 and seal the opening of the consumable 27 containing the packaged item 81, so that the consumable 17 forms a sealed containing space 271, completely enclosing the packaged item 81.

[0066] In another embodiment, when it is necessary to pack the item 81, the lifting mechanism 30 does not need to pass through the through hole 215 and rise to the side where the first surface 215 is located to wait for the item 81 to be placed. The lifting mechanism 30 only needs to stay on the side where the second surface 213 is located to wait for the item 81 to be placed. In this way, the adsorption component 33 does not need to pass through the through hole 215. Instead, the item 81 to be packed passes through the through hole 215 and falls onto the adsorption component 33 on which the consumable 27 is adsorbed. At this time, the size of the adsorption component 33 does not need to be smaller than the aperture of the through hole 215 and can have a larger size to provide a more stable load-bearing capacity. For example, in one example, the height of the item 81 to be packed is higher than the height of the consumable box 21. The item 81 to be packed can be placed directly through the through hole 215 on the adsorption component 33 located on the side where the second surface 213 of the consumable box 21 is located.

[0067] Please see Figures 5 to 7 In one embodiment, the consumable 27 is cylindrical, forming a receiving space 271, and includes an initial closed end 272 and an open end 273 opposite to the closed end 272. The end of the consumable 27 connected to the fixing unit 23 is the open end 273, and the bottom of the receiving space 271 is the closed end 272. The open end 273 faces the through hole 215, allowing the packaged item 81 to be placed into the receiving space 271 from the open end 273. The portion of the consumable 27 between the open end 273 and the closed end 272 is received in a receiving groove 2130. The adsorption component 33 can adsorb the closed end 272 and drag the consumable 27, pulling out a portion of the consumable 27 received in the receiving groove 2130, allowing the consumable 27 to extend any length from the consumable box 21 to package different sizes and quantities of packages 81. The more packages 81 packaged by the consumable 27, and the larger their size, the more of the consumable 27 extends from the consumable receiving mechanism 20. For example, if the item to be packaged 81 is a lunchbox, and one lunchbox needs to be packaged, the adsorption component 33 drags the consumable material 27 relative to the consumable material box 21, causing the consumable material 27 to extend out of the consumable material box 21 by a first length; if two lunchboxes need to be packaged, the consumable material 27 extends out of the consumable material box 21 by a second length, the second length being greater than the first length. Please refer to... Figure 4 The sealing and cutting mechanism 40 can cut off the part of the consumable 27 that extends from the consumable receiving mechanism 20, and can seal the opening of the receiving space 271 containing the package 81 to form a completely sealed receiving space 271, completely enclosing the package 81 inside.

[0068] Please combine Figure 4 In another embodiment, the consumable 27 can be made of a flexible material. After the packaged item 81 is placed into the consumable 27, the lifting mechanism 30 moves the packaged item 81, causing the consumable 27 to extend to form a receiving space 271 that can accommodate the packaged item 81, thus ensuring a tighter wrapping of the packaged item 81 by the consumable 27. The sealing and cutting mechanism 40 can cut off the portion of the consumable 27 that extends out of the receiving space 271 and seal the opening of the receiving space 271 containing the packaged item 81 to form a completely sealed receiving space 271, completely enclosing the packaged item 81 inside.

[0069] Please see Figure 5 In some embodiments, consumable 27 includes a packaging section and a section to be packaged. The packaging section corresponds to the position of the sealing and cutting mechanism 40 and is used to package the item to be packaged 81. The section to be packaged is connected to the consumable box 21 and the packaging section. The sealing and cutting mechanism 40 is used to seal the packaging section, seal the section to be packaged to form a new closed end, and cut the packaging section and the section to be packaged.

[0070] The packaging section and the section to be packaged of the consumable 27 are not pre-defined sections on the consumable 27, but rather sections divided according to packaging requirements. The packaging section of the consumable 27 is determined based on the quantity and size of the items to be packaged 81, adapting to different packaging scenarios. In one embodiment, the sealing and cutting mechanism 40 can cut the consumable 27 extending from the consumable box 21 into two parts. One part remains connected to the consumable box 21 and is the section to be packaged; the other part contains the packaged item and is separated from the section to be packaged, and is the packaging section. Further, when the lifting mechanism 30 moves the consumable 27 and the item to be packaged 81 to the position corresponding to the sealing and cutting mechanism 40, the portion of the consumable 27 that has been cut off from the consumable box 21 by the sealing and cutting mechanism 40 belongs to the packaging section, and the item to be packaged 81 is housed within the packaging section. That is, the packaging section and the section to be packaged can be determined when the consumable 27 moves to the position awaiting cutting.

[0071] Please combine Figure 4 In some embodiments, the consumable box 21 is located above the sealing and cutting mechanism 40, and the consumable 27 is pulled by the adsorption component 33 to a position corresponding to the sealing and cutting mechanism 40 to await cutting and packaging. Before the sealing and cutting mechanism 40 cuts the consumable 27, the packaging part is located below the cutting position of the sealing and cutting mechanism 40 on the consumable 27, and the part to be packaged is located above the cutting position. The part to be packaged is connected to the consumable box 21 and the packaging part; after the sealing and cutting mechanism 40 cuts the consumable 27, the packaging part is separated from the part to be packaged.

[0072] In one embodiment, the sealing and cutting mechanism 40 first cuts the consumable 27 and then packages the cut consumable 27. Since the connection between the packaging section and the section to be packaged is the cylindrical wall of the consumable 27 before cutting, an opening appears at the top of the packaging section and at the bottom of the section to be packaged after cutting. The sealing and cutting mechanism 40 is used to seal the opening at the top of the packaging section to form a completely closed receiving space 271 to wrap the item to be packaged 81; and to seal the opening at the bottom of the section to be packaged to form a new closed end to hold the bottom of the item to be packaged 81 when packaging the next item to be packaged 81.

[0073] In another embodiment, the sealing and cutting mechanism 40 first encapsulates the consumable 27, and then cuts the encapsulated consumable 27. While the consumable 27 is awaiting cutting, the sealing and cutting mechanism 40 first encapsulates the consumable 27 corresponding to the position of the sealing and cutting mechanism 40, for example, by heat sealing, plastic sealing, or glue sealing, sealing the cylindrical wall of the cylindrical consumable 27 horizontally, so that the connected accommodating space 271 forms two non-connected subspaces after sealing. One subspace is located above the sealing point and belongs to the part to be packaged, and the sealing point is the closed end of the part to be packaged; the other subspace is located below the sealing point and belongs to the packaged part. The upper part of the subspace of the packaged part is closed by the sealing point, and the lower part is closed by the initial closed end of the packaged part, forming a sealed accommodating space. The sealing and cutting mechanism 40 is used to cut the sealed part to separate the packaged part and the part to be packaged. After separation, the lower part of the part to be packaged and the upper part of the packaged part are both sealed.

[0074] In another embodiment, the sealing and cutting mechanism 40 simultaneously encapsulates and cuts the consumable 27 to obtain a packaged portion with a new closed end formed below, and a packaged portion that completely encloses the packaged item 81.

[0075] Please see Figure 4 and Figure 8 Specifically, in some embodiments, the adsorption assembly 33 includes a tray 331 and a negative pressure motor 333. The lifting assembly 31 is used to drive the tray 331 to rise and fall.

[0076] More specifically, the tray 331 includes a bearing side 3311 and a mounting side 3315 facing away from each other. A negative pressure motor 333 is mounted on the mounting side 3315, communicates with the tray 331, and is used to evacuate air from the tray 331 to generate an adsorption force on the bearing side 3311.

[0077] Please see Figure 8 and Figure 9 In some embodiments, the bearing side 3311 of the tray 331 is provided with a plurality of suction holes 3313, which are arranged in an array on the bearing side 3311 of the tray 331. Thus, the plurality of suction holes 3313 are evenly distributed on the bearing side 3311, collectively suctioning the consumable 27 and / or the item to be packaged 81. Figure 5 As shown, adsorption occurs, ensuring the adsorption effect of the bearing side 3311. Even if a single adsorption hole 3313 is blocked or other malfunctions occur, the packaged item 81 can still be firmly adsorbed onto the surface of the bearing side 3311, ensuring the flatness of the packaged item 81 and facilitating subsequent packaging work.

[0078] In some embodiments, the tray 331 may be made of metal. The metal plate thus possesses a certain rigidity, ensuring the integrity of the adsorption holes 3313 and preventing blockage of the adsorption holes 3313 by the packaged item 81, thereby increasing the adsorption effect of the surface adsorption force on the bearing side 3311. Of course, in other embodiments, the material of the tray 331 is not limited to the embodiments discussed above, and suitable materials may be used as needed, such as glass, plastic, wood, or other non-metallic materials.

[0079] Please see Figure 9 In some embodiments, the tray 331 may have an air passage 3317 inside, which communicates with the suction hole 3313. A negative pressure motor 333 can communicate with the suction hole 3313 through the air passage 3317. Specifically, the negative pressure motor 333 draws gas from the air passage 3317, creating a vacuum within the air passage 3317. The air passage 3317 then communicates with the suction hole 3313, allowing the suction hole to be used to package the item 81 on the tray 331. Figure 5 (As shown) It generates an adsorption effect to prevent the packaged item 81 from shifting or falling due to vibration or accidental contact.

[0080] In some embodiments, the negative pressure motor 333 can also be a negative pressure pump. The negative pressure motor 333 can be directly mounted on the mounting side 3315 of the tray 331; or the negative pressure motor 333 can be mounted in other locations and communicate with the adsorption hole 3313 through the air passage 3317.

[0081] In some embodiments, the air duct 3317 inside the tray 331 can be designed as a fluid duct, which is connected to the adsorption hole 3313, and the negative pressure motor 333 is also connected to the adsorption hole 3313 through the fluid duct. By adopting a fluid duct design for the air duct 3317, the gas inside the tray 331 is accelerated to be discharged through the negative pressure motor 333, thereby quickly reaching a vacuum state, improving adsorption efficiency. Furthermore, the fluid duct design can reduce the noise caused by the operation of the negative pressure motor 333 to a certain extent, improving the user experience.

[0082] Please see Figure 4 and Figure 8 In some embodiments, the lifting assembly 31 is connected to the mounting side 3315 and is used to drive the lifting of the tray 331. Specifically, the lifting assembly 31 may include a base 311 and a lifting element 313. The base 311 can be rectangular in shape. This makes it easy to cut and shape, and manufacturing is simpler and more convenient. It should be noted that the base 311 can also be rhomboid, triangular, circular, or other desired shapes, which are not limited here. The lifting assembly 31 can be fixed to the bottom of the vending machine 1000 or other devices through the base 311 to ensure the stability of the lifting mechanism 30.

[0083] In some embodiments, the lifting member 313 is mounted on the base 311, and the lifting member 313 includes a body 3131 and a telescopic rod 3133 that can extend and retract relative to the body 3131. The end of the telescopic rod 3133 is fixedly connected to the tray 331. That is, the extension and retraction of the telescopic rod 3133 in the lifting member 313 can drive the tray 331 to move, so that the tray 331 can accurately reach the predetermined position, ensuring the subsequent packaging work.

[0084] In some embodiments, the lifting assembly 31 may further include a position detector 315. The position detector 315 is mounted on the base 311, and part of the structure of the position detector 315 can be raised and lowered with the extension and retraction of the telescopic rod 3133. It is used to detect the position information of the tray 331 relative to the base 311. The lifting assembly 31 can determine the distance of the tray 331 relative to the base 311 based on the position information fed back by the position detector 315, and then control the movement of the tray 331 to ensure that the tray 331 can be accurately moved to the predetermined position.

[0085] In some embodiments, the position detector 315 may include a wire-type displacement sensor. The main body 3151 of the wire-type displacement sensor is mounted on the base 311, and the wire 3153 of the wire-type displacement sensor extends from the main body 3151 and is connected to the mounting side 3315 of the tray 331. Specifically, the wire 3153 of the wire-type displacement sensor is connected to the mounting side 3315 of the tray 331, and the wire 3153 extends and retracts as the lifting mechanism 30 moves. The wire-type displacement sensor contains a sensor that outputs an electrical signal proportional to the moving distance of the wire 3153. By measuring this electrical signal, the displacement, direction, and speed of the tray 331 are determined, thereby controlling the movement of the tray 331. The wire-type displacement sensor has a simple structure, small size, is easy to use, occupies less space, and is more stable.

[0086] In some embodiments, the position detector 315 may include a transmitter and a receiver. The transmitter is mounted on the base 311, and the receiver is mounted on the mounting side 3315; or the transmitter is mounted on the mounting side 3315, and the receiver is mounted on the base 311; this is not limited. The receiver can receive the detection signal transmitted by the transmitter to determine the position of the tray 331 relative to the base 311. For example, the position of the tray 331 relative to the base 311 can be determined by determining the travel distance of the detection signal based on the time from the transmitter transmitting the detection signal to the receiver receiving the detection signal and the speed of the detection signal. In some embodiments, the position detector 315 can also feed back the position information of the tray 331 to the lifting mechanism 30, thereby controlling the precise movement of the tray 331.

[0087] Please see Figure 8In some embodiments, the adsorption assembly 33 may also include a pressure detector 335, which is disposed on the bearing side 3311 of the tray 331 and is used to detect the pressure of the object carried by the tray 331.

[0088] Thus, when the pallet 331 has a package 81 placed on its bearing side 3311, Figure 5 When the pressure detector 335 detects the pressure signal of the packaged item 81, it transmits the pressure signal to the lifting assembly 31, which then activates the lifting assembly 31 to drive the tray 331 to rise or fall. Based on the detected distance, the lifting assembly 31 stops the tray 331 at a predetermined height, facilitating the next packaging step. It should be noted that one or more pressure detectors 335 can be used to avoid detection errors caused by changes in the shape of the packaged item 81, thus improving the error tolerance of the packaging device.

[0089] In some embodiments, the pressure detector 335 is located at the center of the bearing side 3311 of the tray 331; or multiple pressure detectors 335 are evenly distributed on the bearing side 3311 of the tray 331.

[0090] Please see Figure 4 In some embodiments, the consumable box 21 is located on the lifting path of the lifting mechanism 30. In one embodiment, the shape and size of the through hole 215 are matched with the shape and size of the adsorption component 33, so that the adsorption component 33 can pass through the through hole 215.

[0091] Please see Figure 4 , Figure 5 and Figure 8 In some embodiments, when the lifting assembly 31 drives the tray 331 through the through-hole 215 of the consumable box 21 and reaches the position exposed from the through-hole 215, for example, when the bearing side 3311 of the tray 331 is flush with the first surface 211 of the consumable box 21, or when the bearing side 3311 of the tray 331 is slightly higher than the first surface 211 of the consumable box 21, the position detector 315 detects the position information of the tray 331 and feeds the position information back to the lifting assembly 31 to control the lifting assembly 31 to stop lifting. At the same time, the negative pressure motor 333 is turned on, causing the bearing side 3311 to generate an adsorption force to adsorb the consumable 27. When the packaged item 81 is placed on the tray 331, the pressure detector 335 on the adsorption assembly 33 detects the pressure of the packaged item 81 and generates a pressure signal. The pressure detector 335 can feed back the pressure signal to the lifting component 31. The lifting component 31 drives the tray 331 to descend according to the received pressure signal, so as to bring the packaged item 81 down. The consumable 27 moves downward together with the tray 331 under the adsorption of the adsorption component 33, or the consumable 27 is pressed on the tray by the gravity of the packaged item 81 and moves downward together with the tray 331.

[0092] In some embodiments, after the pressure detector 335 generates a pressure signal, the lifting assembly 31 drives the tray 331 to lower the first packaged item 81. When the position detector 315 of the adsorption assembly 33 detects a distance indicating that the tray 331 has fallen by the height of one packaged item 81, the lifting assembly 31 stops driving the tray 331 to lower. At this time, a second packaged item 81 can be placed on top of the first packaged item 81. When the pressure detector 335 generates a pressure signal indicating that a new object has been placed, the lifting assembly 331 can be restarted to lower. When the position detector 315 of the adsorption assembly 33 detects another distance indicating that the tray 331 has fallen by the height of another packaged item 81, the lifting assembly 31 stops driving the tray 331 to lower again. In this way, a third packaged item 81 can be placed on top of the second packaged item 81. This operation continues until all the packages to be packaged have been placed. Then, the lifting assembly 31 drives the tray 331 to lower all the packages to be packaged until they correspond to the sealing and cutting mechanism 40 for sealing.

[0093] Please see Figure 10 In some embodiments, the sealing and cutting mechanism 40 includes a first plate 41, a second plate 43, and a drive assembly 49. The first plate 41 includes a first body 411, a first heat-sealing element 412, and a first cutting element 415. The first heat-sealing element 412 and the first cutting element 415 are disposed on the first body 411. The second plate 43 includes a second body 431, and the second plate 43 is disposed opposite to the first plate 41, with the first heat-sealing element 412 and the first cutting element 415 facing the second plate 43. The drive assembly 49 is used to drive the first plate 41 and the second plate 43 to move away from or towards each other. When the first plate 41 and the second plate 43 are close to each other, the first heat-sealing element 412 and the second body 431 can jointly seal the edges of the packaged portion located between the first plate 41 and the second plate 43, and the first cutting element 415 is used to cut off the sealed packaged portion.

[0094] Please combine Figure 5At the position corresponding to the sealing and cutting mechanism 40, the consumable material 27 is located between the first plate 41 and the second plate 43. After the first plate 41 and the second plate 43 approach each other within a predetermined distance, the first cutting element 415 can cut the consumable material 27, and at the same time, the first heat sealing element 412 can seal the edges of the packaged portion. Alternatively, after the first plate 41 and the second plate 43 approach each other within a first predetermined distance, the first cutting element 415 can cut the consumable material 27, and after the first plate 41 and the second plate 43 approach each other within a second predetermined distance, the first heat sealing element 412 can seal the edges of the packaged portion. Alternatively, after the first plate 41 and the second plate 43 approach each other within a first predetermined distance, the first heat sealing element 412 can seal the edges of the packaged portion, and after the first plate 41 and the second plate 43 approach each other within a second predetermined distance, the first cutting element 415 can cut the consumable material 27. No limitations are imposed here.

[0095] In one example, the drive assembly 49 can drive the first plate 41 and the second plate 43 to move synchronously toward or away from each other. In other embodiments, the drive assembly 49 can also be used to independently drive the first plate 41 toward the direction of the second plate 43, or independently drive the second plate 43 toward the direction of the first plate 41, without limitation.

[0096] In some embodiments, the first heat seal 412 includes a heating wire, and after the first plate 41 and the second plate 43 are brought close to each other by a predetermined distance, the consumable 27 ( Figure 5 As shown, the portion near the first heat seal 412 is molten under the influence of the heat from the heating wire. After the heating wire stops heating for a period of time, or after the first plate 41 and the second plate 43 have moved away from each other by a predetermined distance, the molten material 27 solidifies to form a sealing edge.

[0097] Please see Figure 10 and Figure 11 In some embodiments, the first plate 41 may further include a second heat-sealing member 413 disposed on the first body 411. The second heat-sealing member 413 is located on the side of the first heat-sealing member 412 opposite to the first cutting member 415 and is spaced apart from the first heat-sealing member 412. The first heat-sealing member 412, the second heat-sealing member 413, and the second body 431 can jointly seal the edge of the packaging portion located between the first plate 41 and the second plate 43 to form a sealing portion 274 (e.g., Figure 6 and Figure 7 (As shown).

[0098] The greater the distance between the first heat seal 412 and the second heat seal 413, the larger the size of the formed sealing portion 274 (e.g., ...). Figure 7The larger the dimension in the height direction. In one embodiment, the first heat seal 412 and the second heat seal 413 are movably disposed on the first plate 41, and the distance between the first heat seal 412 and the second heat seal 413 is adjustable to form sealing portions 274 of different sizes.

[0099] In some embodiments, one of the first heat-sealing member 412 and the second heat-sealing member 413 may be disposed in the first body 411 and the other in the second body 431; or both the first heat-sealing member 412 and the second heat-sealing member 413 may be disposed in the second body 431 and the first cutting member 415 may be disposed in the first body 411, without limitation.

[0100] Please continue reading. Figure 10 and Figure 11 In some embodiments, the first plate 41 may further include a second cutting member 416 disposed on the first body 411. The second cutting member 416 is located between the first heat sealer 412 and the second heat sealer 413, and is used to cut a handle opening 275 on the sealing portion 274. Figure 6 (As shown), so that the user can carry the packaged item 80. In some embodiments, the second cutter 416 is also used to cut out perforated trademarks, text, patterns, etc. on the sealing portion 274, which is not limited here.

[0101] In some embodiments, the second cutting element 416 may also be disposed on the second body 431, which is not limited here.

[0102] Please refer to [link / reference] Figure 10 and Figure 11 In some embodiments, the second body 431 may be provided with a first clearance space 4311, which is used to avoid the first cutting element 415, so as to prevent the first cutting element 415 from cutting the second body 431. Similarly, in some embodiments, the second body 431 may also be provided with a second clearance space 4313, which is used to avoid the second cutting element 416, so as to prevent the second cutting element 416 from cutting the second body 431.

[0103] Please see Figure 10 In some embodiments, the first plate 41 may further include a third heat sealer 414 disposed on the first body 411, the third heat sealer 414 and the second body 431 being able to jointly seal the consumable 27 ( Figure 5 (As shown) Seal the edges to form a new closed end for the part to be packaged.

[0104] In some embodiments, the first cutting element 415 is located between the first heat sealer 412 and the second heat sealer 413. (Please refer to...) Figure 4When the consumable receiving mechanism 20 is located above the sealing and cutting mechanism 40, and the packaged item 81 corresponds to the sealing and cutting mechanism 40, the consumable item 27 located above the first cutting member 415 is the part to be packaged, and the consumable item 27 located below the first cutting member 415 is the packaged part. The third heat sealer 414 can seal the lower end of the part to be packaged to form a new closed end, and the first heat sealer 412 and the second heat sealer 413 are used together to seal the upper end of the packaged part to form a sealed edge 274.

[0105] Please see Figure 10 and Figure 11 In some embodiments, the second plate 43 may further include a first protrusion 432. The first protrusion 432 extends from the second body 431 toward the first body 411, and the first protrusion 432 cooperates with the first heat sealer 412 to jointly seal the packaging portion located between the first plate 41 and the second plate 43, so as to prevent the first heat sealer 412 from directly contacting the second plate 43 and causing burns to the second plate 43. The first protrusion 432 corresponds to the position of the first heat sealer 412.

[0106] Similarly, in some embodiments, the second plate 43 may further include a second protrusion 433. The second protrusion 433 extends from the second body 431 toward the first body 411, and the second protrusion 433 cooperates with the second heat sealer 413 to jointly seal the packaging portion located between the first plate 41 and the second plate 43. The second protrusion 433 and the second heat sealer 413 are positioned correspondingly.

[0107] Similarly, in some embodiments, the second plate 43 may also include a third protrusion 434. The third protrusion 434 extends from the second body 431 toward the first body 411, and the third protrusion 434 cooperates with the third heat sealer 414 to jointly seal the packaging portion located between the first plate 41 and the second plate 43. The third protrusion 434 and the third heat sealer 414 are positioned correspondingly.

[0108] Please see Figure 11 In some embodiments, the packaging device 100 may also include a shaping assembly (45 / 47) for tensioning the consumable 27 between the first plate 41 and the second plate 43 to facilitate cutting and sealing.

[0109] In some embodiments, the packaging device 100 includes two first shaping components 45 disposed on a first body 411 and two second shaping components 47 disposed on a second body 431, each second shaping component 47 corresponding to one first shaping component 45. A first heat seal 412, a second heat seal 413, and a third heat seal 414 are all located between the two first shaping components 45, and a first protrusion 432, a second protrusion 433, and a third protrusion 434 are all located between the two second shaping components 47. The two first shaping components 45 and the two second shaping components 47 work together to tension the consumable 27 between the first plate 41 and the second plate 43 to facilitate cutting and sealing.

[0110] In some embodiments, the first shaping assembly 45 and / or the second shaping assembly 47 may include two spaced-apart elastic members and a shaping rod connecting the two elastic members. The elastic members are used to provide elastic force to the shaping rod, causing the shaping rod to press the consumable 27 between the first plate 41 and the second plate 43 to tension the consumable 27.

[0111] Please see Figure 10 and Figure 11 In one embodiment, the first shaping assembly 45 includes two first elastic elements 451 and a first shaping rod 453 connecting the two first elastic elements 451, and the second shaping assembly 47 includes two second elastic elements 471 and a second shaping rod 473 connecting the two second elastic elements 471. During the process of the first plate 41 and the second plate 43 approaching each other, the first shaping rod 453 and the second shaping rod 473 first contact and abut against the consumable 27. Subsequently, the first plate 41 and the second plate 43 continue to approach each other against the elastic force of the first elastic elements 451 and the second elastic elements 471. Under the action of the elastic force, the first shaping rod 453 and the second shaping rod 473 compress the consumable 27, causing the consumable 27 between the first plate 41 and the second plate 43 to be tensioned, so as to facilitate the flat cutting and edge sealing of the consumable 27.

[0112] In other embodiments, either the first shaping component 45 or the second shaping component 47 may include an elastic element and a shaping rod, without limitation.

[0113] Please see Figure 10 and Figure 12 In some embodiments, the drive assembly 49 may include a drive member 491, a first lead screw 496, and a second lead screw 497. The drive member 491 is mounted on the side wall 11. Please refer to... Figure 2The first lead screw 496 is rotatably mounted on one side of the sidewall 11 via a bearing housing assembly and includes a positive thread section and a negative thread section. The second lead screw 497 is rotatably mounted on the other side of the sidewall 11 via another bearing housing assembly 102 and includes a positive thread section and a negative thread section. The positive thread sections of the first lead screw 496 and the second lead screw 497 pass through opposite sides of the first plate 41, and the negative thread sections of the second lead screw 497 pass through opposite sides of the second plate 43. The driving member 491 is used to drive the first lead screw 496 and the second lead screw 497 to rotate so that the first plate 41 and the second plate 43 move synchronously to move away from or towards each other.

[0114] Please see Figure 12 In some embodiments, bearing housing assembly 101 may include a first bearing housing 13 and a second bearing housing 14, and bearing housing assembly 102 may include a third bearing housing 15 and a fourth bearing housing (not shown). A first lead screw 496 is disposed between the first bearing housing 13 and the second bearing housing 14, and a second lead screw 497 is disposed between the third bearing housing 15 and the fourth bearing housing.

[0115] Please see Figure 11 In some embodiments, the drive member 491 can drive the first lead screw 496 and the second lead screw 497 to rotate synchronously, thereby causing the first plate 41 and the second plate 43 to move along the axial direction of the lead screw. The first plate 41 is connected to the positive threaded section of both the first lead screw 496 and the second lead screw 497, and the second plate 43 is connected to the negative threaded section of both the first lead screw 496 and the second lead screw 497. Thus, when the first lead screw 496 and the second lead screw 497 rotate synchronously, the first plate 41 and the second plate 43 move in opposite directions along the axial direction of the lead screw. This allows the drive member 491 to drive the first lead screw 496 and the second lead screw 497 to rotate synchronously, causing the first plate 41 and the second plate 43 to move closer to or further away from each other.

[0116] In some embodiments, the first lead screw 496 and the second lead screw 497 are of the same length. The positive thread section and the negative thread section of the first lead screw 496 are symmetrically arranged with respect to the midpoint of the first lead screw 496 along its length direction, and the positive thread section and the negative thread section of the second lead screw 497 are symmetrically arranged with respect to the midpoint of the second lead screw 497 along its length direction. In this way, the travel distance of the first plate 41 along the positive thread section is the same as the travel distance of the second plate 43 along the negative thread section.

[0117] Please see Figure 10In some embodiments, the drive assembly 49 may further include a drive wheel 492, a tension wheel 498, a first driven wheel 493, a second driven wheel 494, and a transmission belt 495. The drive wheel 492 is connected to the drive member 491. The tension wheel 498 is rotatably mounted on the side wall 11. The first driven wheel 493 is rotatably mounted on the side wall 11 and connected to a first lead screw 496. The second driven wheel 494 is rotatably mounted on the side wall 11 and connected to a second lead screw 497. The transmission belt 495 is sleeved on the drive wheel 492, the tension wheel 498, the first driven wheel 493, and the second driven wheel 494, and drives the first driven wheel 493 and the second driven wheel 494 to rotate when the drive member 491 drives the drive wheel 492 to rotate. The tension wheel 498 is used to tension the transmission belt 495 to ensure stable transmission by the transmission belt 495.

[0118] In one embodiment, the driving component 491 is a drive motor, the transmission wheel 492 is connected to the output shaft of the drive motor, and the transmission wheel 492 transmits the driving force to the first driven wheel 493 and the second driven wheel 494 through the transmission belt 495, so as to drive the first driven wheel 493 and the second driven wheel 494 to rotate, and make the first lead screw 496 and the second lead screw 497 rotate synchronously.

[0119] Please see Figure 13 In some embodiments, the drive assembly 49 may also include two drive members (not shown in the figure). The two drive members are respectively connected to the first lead screw 496 passing through the second bearing seat 14 and the second lead screw 497 passing through the third bearing seat 15. When the two drive members work synchronously, they can directly drive the first lead screw 496 and the second lead screw 497 to rotate synchronously, thereby driving the first plate 41 and the second plate 43 to move closer to or further away from each other.

[0120] Please see Figure 2 and Figure 4 In some embodiments, the packaging device 100 may further include a printing mechanism 50. The printing mechanism 50 is movably disposed on the side wall 11 and is used to spray food information onto the packaging portion. The food information may include the food's merchant information, name, production date, etc., and is not limited thereto.

[0121] In some embodiments, the sidewall 11 is provided with a guide rod 16, the printing mechanism 50 is movably mounted on the guide rod 16, and can slide along the guide rod 16 to spray at different positions.

[0122] Please combine Figure 11 In some embodiments, the printing mechanism 50 includes a driver 501 and a printhead 503. The driver 501 drives the printhead 503 to slide along the guide rod 16. The printhead 503 is used to spray food information onto the packaging section.

[0123] Please see Figure 2In some embodiments, the consumable receiving mechanism 20 may further include a connecting plate 25, which is fixedly connected to the side wall 11 to fix the consumable receiving mechanism 20 to the frame 10.

[0124] Please see Figure 2 , Figure 4 and Figure 7 In some embodiments, the packaging device 100 may further include a cutlery dispensing mechanism 60 mounted on the top wall 12. The cutlery dispensing mechanism 60 is used to dispense cutlery 83 onto the package 81 to be packaged, which is supported on the tray 331 of the adsorption assembly 33. (Please refer to...) Figure 8 In one embodiment, the packaged item 81 is a lunch box. A lunch box can be placed on the tray 331 of the adsorption component 33, or multiple lunch boxes can be stacked in sequence.

When a force command is received, the control drive 317 drives the lifting component 313 to lower the tray 331 until the control unit 70 receives the fourth position command from the position detector 315 and stops lowering. The control unit 70 then controls the drive assembly 49 to drive the first plate 41 and the second plate 43 closer together. After the drive assembly 49 drives the first plate 41 and the second plate 43 closer together for a predetermined time, the control unit 70 controls the drive assembly 49 to drive the first plate 41 and the second plate 43 further apart. After the drive assembly 49 drives the first plate 41 and the second plate 43 further apart for a predetermined time, the control unit 70 controls the drive drive 317 to drive the lifting component 313 to lower the tray 331 until the control unit 70 receives the fifth position command from the position detector 315 and stops lowering. The control unit 70 then controls the printhead 503 to start printing.

[0127] The first position command indicates that the tray 331 has reached a position where it is exposed from the first side 211 of the consumable box 21. The first pressure command indicates that one food container is placed on the tray 331. The second position command indicates that the tray 331 has reached a position where it can hold a second food container. The second pressure command indicates that two food containers are placed on the tray 331. The third position command indicates that the tray 331 has reached a position where it can hold tableware 83. The third pressure command indicates that two food containers and one set of tableware 83 are placed on the tray 331. The fourth position command indicates that the tray 331 has reached a position where the packaging part of the consumable 27 corresponds to the sealing and cutting mechanism 40. The fifth position command indicates that the tray 331 has reached a position where the food container corresponds to the nozzle 503.

[0128] In some embodiments, the control unit 70 is also used to acquire printing information input by the user and send the printing information to the printhead 503 so that the printhead 503 can print according to the printing information.

[0129] Please see Figure 1In some embodiments, the conveying structure 500 is housed within the housing 300 and is used to place the packaged item 81 to be packaged into the packaging device 100 and to remove the packaged item 81 packaged with consumable 27 from the packaging device 100.

[0130] Please see Figure 3 The housing 90 may be provided with an inlet 91 and an outlet 93. The conveying structure 500 is used to convey the items to be packaged 81 (such as...) Figure 7 As shown, the packaged item 81, which is packaged with consumable 27, is fed into the packaging device 100 through the inlet 91 and taken out through the outlet 93.

[0131] Please refer to the following: Figure 1 , Figure 2 and Figure 7 In some embodiments, the conveying structure 500 includes a feeding structure and a discharging structure. The feeding structure is used to feed the packaged item 81 from the inlet 91 into the packaging device 100, for example, by placing the packaged item 81 in the lifting mechanism 30. In one embodiment, the feeding structure is housed within the housing 300 and can extend outside the housing 300 to retrieve the packaged item 81 from outside the vending machine 1000. In another embodiment, the vending machine 1000 can produce the packaged item 81 within the housing 300, and the feeding structure is used to place the packaged item 81 produced by the vending machine 1000 in the lifting mechanism 30. The discharging structure is used to remove the packaged item 80 from the discharging port 93. In one embodiment, the discharging structure can extend outside the housing 300 to output the packaged item 80 outside the housing 300.

[0132] In some embodiments, when the control unit 70 receives a first position command from the position detector 315, the control unit 70 controls the feeding structure to place the package 81 to be packaged onto the tray 331. When the printhead 503 completes printing, the control unit 70 controls the dispensing structure to retrieve and remove the package 80 from the tray 331. Alternatively, printing on the package 80 may not be performed; instead, after the drive assembly 49 drives the first plate 41 and the second plate 43 away from each other for a predetermined period of time, the control unit 70 controls the dispensing structure to retrieve and remove the package 80 from the tray 331.
