[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] This application provides an automatic bag sealing device, wherein "bag sealing" refers to sealing the bag containing the packaged items with a cable tie.

[0033] like Figures 1-5As shown, the automatic bag sealing device 3 includes a frame 10, a compression mechanism, a lifting drive, a rotating drive 30, and a tie-sealing mechanism. The compression mechanism includes a main body 20, a compression drive 21, and multiple clamping components 22 that can clamp / release the edge of the bag opening of the packaging bag 1. The multiple clamping components 22 are disposed on the main body 20 and distributed at intervals along the circumference of the main body 20. The compression drive 21 is disposed on the main body 20 and can drive the multiple clamping components 22 away from / close to the center line of the main body 20 to expand / contract the bag opening of the packaging bag 1. The lifting drive is disposed on the frame 10 and can drive the rotating drive 30 to lift the main body 20. The rotating drive 30 can drive the main body 20 to rotate, thereby driving the multiple clamping components 22 to rotate to tighten the bag opening of the packaging bag 1. The tie-sealing mechanism is disposed on the frame 10 and is used to tie the bag opening of the tightened packaging bag 1 with a tie 44.

[0034] Optionally, a single expansion / contraction drive component 21 can be provided. The output end of the expansion / contraction drive component 21 is connected to multiple clamping components 22 via a linkage mechanism, enabling one expansion / contraction drive component to simultaneously drive multiple clamping components 22 to move, so that the multiple clamping components 22 simultaneously move away from / approach the centerline of the main body 20. Alternatively, multiple expansion / contraction drive components 21 can be provided, with the output ends of multiple expansion / contraction drive components 21 directly connected to multiple clamping components 22 in a one-to-one correspondence, enabling multiple expansion / contraction drive components to directly drive multiple clamping components 22 to move, so that the multiple clamping components 22 simultaneously move away from / approach the centerline of the main body 20. Specifically, the centerline of the main body 20 extends vertically. With multiple clamping components 22 clamping the edge of the bag opening of the packaging bag 1, when the expansion / contraction drive component 21 drives multiple clamping components 22 to move away from the centerline of the main body 20 simultaneously, the bag opening of the packaging bag 1 is expanded; when the expansion / contraction drive component 21 drives multiple clamping components 22 to move closer to the centerline of the main body 20 simultaneously, the bag opening of the packaging bag 1 is contracted. The expansion drive component 21 can be an electric push rod, a cylinder, a hydraulic cylinder, or a linear motor, preferably an electric push rod. Electric push rods are small in size, have high precision, and do not require a pipeline air source or oil circuit.

[0035] The automatic bag sealing device 3 provided in this application embodiment, when it is necessary to seal a bag 1 filled with package 2, uses a lifting drive to drive a rotating drive 30 to lower the main body 20 to approach the bag 1. Multiple clamping components 22 of the expansion and contraction mechanism clamp the edge of the bag opening of the bag 1, which can prevent the bag opening from loosening during the subsequent shrinking and rotation process. After clamping, the expansion and contraction drive 21 drives the multiple clamping components 22 to approach the center line of the main body 20 to shrink the bag opening of the bag 1. At the same time as shrinking the bag opening, the rotating drive 30 drives the main body 20 to rotate. When the main body 20 rotates, it will drive the multiple clamping components 22 to rotate together to tighten the bag opening of the bag 1. After the bag opening of the bag 1 is tightened, it is sealed by a tie 44 through a tie-sealing mechanism, thereby realizing automatic bag sealing. Compared with the manual bag sealing method, the automatic bag sealing device 3 effectively improves the efficiency of bag sealing operation and reduces the workload of personnel.

[0036] For example, in the express delivery industry, small-sized express packages with regular shapes are usually called small parcels. Small parcels are transported together using bulk bags, and the flow of small parcels in the same bulk bag is consistent. Since bulk bags are flexible objects, the number, weight, and volume of express parcels in each bulk bag are different, which brings great difficulties and challenges to the success rate and reliability of sealing the bags. Therefore, the existing technology uses manual operation in the sealing process. However, the automatic sealing device 3 provided in this application embodiment can realize automated sealing. Therefore, using the automatic sealing device 3 provided in this application embodiment to replace manual sealing of bulk bags full of small parcels can greatly save labor and significantly improve the sealing speed compared to manual operation, thereby improving operational efficiency.

[0037] like Figure 3As shown, in some embodiments of this application, the expansion and contraction mechanism further includes a fixed member 23, a movable member 24, and multiple linkage assemblies 25. Each linkage assembly 25 corresponds to one clamping assembly 22. The fixed member 23 is fixed to the main body 20. The movable member 24 is connected to the output end of the expansion and contraction drive member 21, which drives the movable member 24 to rise and fall. Each clamping assembly 22 is rotatably connected to the fixed member 23 and the movable member 24 via a linkage assembly 25. Optionally, the output end of the expansion and contraction drive member 21 can extend and retract vertically to drive the movable member 24 to rise and fall; alternatively, the expansion and contraction drive member 21 can also rise and fall as a whole to simultaneously drive the movable member 24 to rise and fall. With multiple clamping components 22 clamping the edge of the bag opening 1, when the expansion and contraction drive 21 drives the movable component 24 to rise or fall, it can move the multiple clamping components 22 away from / near the center line of the main body 20, thereby expanding / contracting the bag opening 1. Specifically: when the expansion and contraction drive 21 drives the movable component 24 to fall, it will move the multiple clamping components 22 away from the center line of the main body 20, causing the bag opening 1 to be expanded; when the expansion and contraction drive 21 drives the movable component 24 to rise, it will move the multiple clamping components 22 closer to the center line of the main body 20, causing the bag opening 1 to be contracted. Preferably, there are two expansion and contraction drive components 21, and the output ends of the two expansion and contraction drive components 21 are respectively connected to the two opposite sides of the movable component 24, so that the movable component 24 is subjected to uniform force and the lifting and lowering is more stable.

[0038] Optionally, the main body 20 is provided with a vertical guide rod 26, a fixing member 23 is connected to the bottom end of the vertical guide rod 26, a movable member 24 is slidably sleeved on the vertical guide rod 26, and a expansion and contraction drive member 21 is provided on the vertical guide rod 26. The expansion and contraction drive member 21 can drive the movable member 24 to rise and fall along the vertical guide rod 26. The setting of the vertical guide rod 26 improves the stability of the movable member 24 when it rises and falls. Alternatively, a guide rail extending in the vertical direction can be provided on the vertical guide rod 26, and a slider can be provided on the movable member 24. The slider slides with the guide rail to realize the rise and fall of the movable member 24 along the vertical guide rod 26.

[0039] like Figure 3 and Figure 4As shown, in some embodiments of this application, the linkage assembly 25 includes a first linkage 251, a second linkage 252, and a third linkage 253. The two ends of the first linkage 251 are rotatably connected to the upper end of the movable member 24 and the clamping assembly 22, respectively. The two ends of the second linkage 252 are rotatably connected to the lower end of the movable member 24 and the clamping assembly 22, respectively. The second linkage 252 is parallel to the first linkage 251. The two ends of the third linkage 253 are rotatably connected to the middle part of the second linkage 252 and the fixing member 23, respectively. The clamping assembly 22, through the linkage assembly 25 with the above structure, rotatably connects the fixing member 23 and the movable member 24, enabling the movable member 24 to move multiple clamping assemblies 22 away from / close to the centerline of the main body 20 when it is raised or lowered, thereby opening / closing the bag opening of the packaging bag 1.

[0040] Optionally, the clamping assembly 22 may include two driving members and two movable clamping members. The two driving members drive the two movable clamping members to move in a one-to-one correspondence, so that the two movable clamping members move towards each other or away from each other, so as to clamp / release the edge of the bag opening of the packaging bag 1. Alternatively, the clamping assembly 22 may also include a driving member, a fixed clamping member and a movable clamping member. The fixed clamping member is fixed and stationary, and the movable clamping member can move closer to or away from the fixed clamping member under the drive of the driving member, so as to clamp / release the edge of the bag opening of the packaging bag 1.

[0041] like Figure 3 and Figure 4 As shown, in some embodiments of this application, the clamping assembly 22 includes a support claw 221, a clamping member 222, and a clamping drive member 223. The support claw 221 is connected to the output end of the clamping drive member 21, and both the clamping member 222 and the clamping drive member 223 are disposed on the support claw 221. The clamping member 222 is rotatably connected to the output ends of the support claw 221 and the clamping drive member 223, respectively. The clamping drive member 223 can drive the clamping member 222 to move closer to / away from the support claw 221, so that the clamping member 222 clamps / releases the edge of the bag opening of the packaging bag 1 with the support claw 221. Specifically, when the linkage assembly 25 includes a first linkage 251, a second linkage 252, and a third linkage 253, the two ends of the first linkage 251 are rotatably connected to the upper end of the movable member 24 and the upper end of the support claw 221, respectively, and the two ends of the second linkage 252 are rotatably connected to the lower end of the movable member 24 and the middle part of the support claw 221, respectively.

[0042] The clamping drive component 223 can be an electric push rod, a pneumatic cylinder, a hydraulic cylinder, or a linear motor, preferably an electric push rod. Electric push rods are small in size, have high precision, and do not require a pneumatic or hydraulic supply line. They can drive the clamping component 222 to move closer to or further away from the support claw 221 via extension and retraction. Specifically, when the clamping drive component 223 is an electric push rod, the clamping component 222 is connected to the push rod of the electric push rod. When the push rod extends or retracts, it drives the clamping component 222 to move closer to or further away from the support claw 221. When the clamping drive component 223 is a pneumatic or hydraulic cylinder, the clamping component 222 is connected to the piston rod of the pneumatic or hydraulic cylinder. When the piston rod extends or retracts, it drives the clamping component 222 to move closer to or further away from the support claw 221. When the clamping drive component 223 is a linear motor, the clamping component 222 is connected to the secondary board of the linear motor. When the secondary board performs linear reciprocating motion, it drives the clamping component 222 to move closer to or further away from the support claw 221.

[0043] Optionally, the number of clamping components 22 can be two, three, four, or five or more, depending on actual needs. For example, such as... Figure 3 As shown, there are four clamping components 22. The four clamping components 22 are evenly distributed around the circumference of the main body 20. The four clamping components 22 clamp the four corners of the bag opening of the packaging bag 1 respectively. The four clamping components 22 can open and close the bag opening of the packaging bag 1 under the drive of the expansion and contraction drive component 21.

[0044] like Figure 5 As shown, the cable tie sealing mechanism includes a cable tie feeding mechanism 41, a cable tie binding mechanism 42, and a sealing drive component 43. The cable tie feeding mechanism 41 is used to feed cable ties 44 into the cable tie hopper of the cable tie binding mechanism 42. The sealing drive component 43 can drive the cable tie binding mechanism 42 to move closer to / away from the opening of the tightened packaging bag 1. The cable tie binding mechanism 42 is used to bind the cable ties 44 to the opening of the tightened packaging bag 1 to achieve bag sealing. The cable tie feeding mechanism 41 can be a winding cable tie conveyor mechanism. The specific structures of the cable tie feeding mechanism 41 and the cable tie binding mechanism 42 can be found in existing technologies and will not be described in detail here. The sealing drive component 43 can be an electric push rod, a cylinder, a hydraulic cylinder, or a linear motor.

[0045] In some embodiments of this application, the cable tie 44 includes a marking section 441 and a binding section 442. The marking section 441 has a slit 443 at one end near the binding section 442, through which the binding section 442 passes and is secured. The automatic sealing device 3 also includes a marking mechanism for marking the marking section 441, which is mounted on the frame 10. Marking the marking section 441 of the cable tie 44 with an identification code facilitates management. For example, after sealing a package 1 filled with express parcels using the cable tie 44, a destination identification code can be marked on the marking section 441 of the cable tie 44.

[0046] Optionally, the automatic bag sealing device 3 also includes a clamping mechanism mounted on the frame 10. The clamping mechanism includes a first clamping member 51 for clamping the packaging bag 1 and a clamping drive member 52 for driving the first clamping member 51 closer to / away from the packaging bag 1. The clamping drive member 52 can be an electric push rod, a cylinder, a hydraulic cylinder, or a linear motor. Optionally, the first clamping member 51 can include a first clamping plate, a second clamping plate, and a third clamping plate, which are sequentially connected to form a C-shaped structure. The angle between the first clamping plate and the second clamping plate is obtuse, and the angle between the second clamping plate and the third clamping plate is also obtuse. The output end of the clamping drive member 52 is connected to the second clamping plate. Preferably, to avoid damage to the packaged item 2 due to hard contact during clamping, a buffer block 70 can be provided on the side of the first clamping member 51 facing the packaging bag 1. The buffer block 70 can be made of rubber or sponge.

[0047] Figures 1-5 The working principle of the automatic bag sealing device 3 shown is as follows:

[0048] When the bag 1 filled with the packaged item 2 is moved to the sealing station, the lifting drive drives the rotation drive 30 to lower the main body 20, causing multiple clamping components 22 on the main body 20 to descend to the bag opening position of the bag 1. The expansion drive 21 drives the multiple clamping components 22 away from the center line of the main body 20 so that the multiple support claws 221 open. The clamping drive 223 drives the clamping components 222 to move closer to the support claws 221 and together with the support claws 221 clamp the edge of the bag opening of the bag 1. After clamping, the lifting drive drives the rotation drive 30 to slightly raise the main body 20 to organize the packaged item 2 in the bag 1. The clamping drive 52 drives the first clamping component 51 to move closer to the bag 1 to slightly clamp the bag 1. Then, the expansion drive 21 drives the multiple clamping components 22 to move closer to the center line of the main body 20 to close the bag opening of the bag 1. At the same time as closing the bag opening, the rotation drive 30 drives the main body 20 to close the bag opening of the bag 1. The body 20 drives multiple clamping components 22 to rotate together, thereby tightening the bag opening of the packaging bag 1. At the same time, the cable tie feeding mechanism 41 feeds a cable tie 44 to the hopper of the cable tie binding mechanism 42. The cable tie binding mechanism 42 cuts the connection of the cable tie 44, and the marking mechanism marks the identification code onto the marking part 441 of the cable tie 44. After the bag opening of the packaging bag 1 is tightened, the cable tie binding mechanism 42 seals the bag opening with the cable tie 44. Then, the clamping drive 52 drives the first clamping member 51 away from the packaging bag 1 to release the packaging bag 1. The clamping drive 223 drives the clamping member 222 away from the support claw 221 to release the edge of the bag opening of the packaging bag 1. The expansion drive 21 drives multiple clamping components 22 to move closer to the center line of the body 20 so that the multiple support claws 221 further contract. Finally, the lifting drive drives the rotation drive 30 to lift the body 20, so that the clamping components 22 leave the bag opening position of the packaging bag 1.

[0049] This application also provides an automatic packaging system, such as... Figure 6 As shown, the automatic packaging system includes a first conveying mechanism 5, a transfer device 4, a handling robot 6, a second conveying mechanism 7, and an automatic sealing device 3 according to any of the above embodiments. The first conveying mechanism 5 is used to convey the package to be packaged 2; the transfer device 4 is used to move the empty packaging bag 1 to the outlet of the first conveying mechanism 5 to receive the package to be packaged 2, and to move the packaging bag 1 containing the package to be packaged 2 to the position of the automatic sealing device 3 for sealing; the handling robot 6 is used to grab the sealed packaging bag 1 onto the second conveying mechanism 7, and the second conveying mechanism 7 is used to transport the sealed packaging bag 1 to a designated position. The automatic packaging system provided in this application embodiment can realize a series of processes such as automatic bagging and sealing, effectively improving the efficiency of packaging operations and reducing the workload of personnel.

[0050] The first conveyor 5 can be a belt conveyor with baffles on both sides of the belt. Located below the sorting slots of the sorting machine, the first conveyor 5 receives the packages 2 (e.g., express parcels) unloaded from the sorting slots and conveys them to the transfer device 4 for bagging. The second conveyor 7 can also be a belt conveyor with baffles on both sides of the belt. The second conveyor 7 conveys the sealed bags 1 to a designated location (e.g., a loading point). The handling robot 6 can include an industrial robotic arm and an end effector gripper. The industrial robotic arm drives the end effector gripper to grab the sealed bags 1 and place them onto the second conveyor 7.

[0051] In some embodiments of this application, the transfer device 4 includes a transfer platform and a bagging mechanism 63. The transfer platform can move the bagging mechanism 63 to the outlet of the first conveying mechanism 5 and the position of the automatic sealing device 3. The bagging mechanism 63 includes a bagging frame and two bagging assemblies symmetrically arranged on the bagging frame, such as... Figure 8 As shown, each bagging assembly includes a bagging drive 633 and two hooks 634 for supporting the opening of the packaging bag 1. The bagging drive 633 can drive the two hooks 634 to move away from each other or closer together. Specifically, when bagging, the bagging drive 633 drives the two hooks 634 closer together, making it easier for the worker to put the empty packaging bag 1 onto the hooks 634 of the two bagging assemblies; after bagging, the bagging drive 633 drives the two hooks 634 away from each other, so as to open the opening of the packaging bag 1.

[0052] like Figure 7As shown, in some embodiments of this application, the transfer platform includes a rotating base 61 and a mounting plate 62. The mounting plate 62 is mounted on the rotating base 61, and the rotating base 61 is provided with a turntable drive component that can drive the mounting plate 62 to rotate. The turntable drive component can be a rotary motor or a rotary cylinder. A bagging station, a receiving station, a sealing station, and a transfer station are sequentially arranged along the circumference of the rotating base 61. A bagging mechanism 63 is provided on the mounting plate 62 corresponding to each of the bagging station, receiving station, sealing station, and transfer station. The mounting plate 62 can be designed in a quincunx shape. Specifically, before receiving the goods, a worker places an empty packaging bag 1 onto the bagging mechanism 63 at the bagging station. The mounting plate 62 rotates 90° each time, sequentially moving from the bagging station to the receiving station, sealing station, and transfer station, and finally returning to the bagging station, thus repeating the cycle. This application improves packaging efficiency by sequentially setting up a bagging station, a receiving station, a sealing station, and a transfer station around the circumference of the mounting plate 62, thereby enabling the simultaneous execution of four processes: bagging, receiving, sealing, and transfer.

[0053] like Figure 8 As shown, in some embodiments of this application, the hook 634 is rotatably connected to the bagging frame. The bagging assembly also includes a first elastic element 635 and a bagging connecting rod 636. The two ends of the bagging connecting rod 636 are rotatably connected to the lower end of the hook 634 and the output end of the bagging drive 633, respectively. The bagging drive 633 can drive the bagging connecting rod 636 to rise and fall. The two ends of the first elastic element 635 are connected to the lower end of the hook 634 and the bagging frame, respectively. In other words, the lower end of each hook 634 is connected to the output end of the bagging drive 633 via the bagging connecting rod 636, and the lower end of each hook 634 is also connected to the bagging frame via the first elastic element 635. The first elastic element 635 can be a tension spring.

[0054] Specifically, during bagging, the bagging drive 633 drives the bagging connecting rod 636 to rise, causing the hooks 634 to rotate around their rotational connection point with the bagging frame, bringing the upper ends of the two hooks 634 closer together. This makes it easier for workers to put the empty bag 1 onto the upper ends of the hooks 634 of the two bagging components. At this time, the first elastic element 635 is stretched. After bagging is completed, the bagging drive 633 drives the bagging connecting rod 636 to fall, causing the hooks 634 to rotate around their rotational connection point with the bagging frame, moving the upper ends of the two hooks 634 further apart. At this time, the first elastic element 635 is compressed, and the hooks 634 tighten the bag opening of the bag 1 under the elastic restoring force of the first elastic element 635.

[0055] like Figure 8As shown, the bagging frame includes a base 630 and two support components symmetrically arranged on the base 630. The two bagging components are correspondingly mounted on the two support components. Each support component includes a column 631 and a crossbeam 632 located at the top of the column 631. A bagging drive component 633 is located on the column 631. Two hooks 634 of the same bagging component are rotatably connected to both ends of the crossbeam 632. A first elastic element 635 is located between the crossbeam 632 and the bagging connecting rod 636. The bagging frame structure described above is simple, and a larger space can be left between the two support components for placing the packing bag 1.

[0056] In some embodiments of this application, the bagging mechanism 63 further includes a clamping assembly, such as... Figure 8 As shown, the clamping assembly includes a support frame 637, a second elastic element 638, and a second clamping element 639 for clamping the packing bag 1. The support frame 637 is rotatably mounted on the bag-covering frame, and the second clamping element 639 is mounted on the support frame 637. The two ends of the second elastic element 638 are connected to the support frame 637 and the bag-covering frame, respectively. By setting up the clamping assembly, the packing bag 1 filled with the packaged item 2 can be held in place, preventing the packing bag 1 from collapsing. The second elastic element 638 can be a compression spring. The elastic restoring force generated after the second elastic element 638 is compressed allows the second clamping element 639 to maintain a certain clamping force. That is, when the packing bag 1 is filled with the packaged item 2, the packaged item 2 compresses the second elastic element 638 by contacting the second clamping element 639. The elastic restoring force generated after the second elastic element 638 is compressed will push the support frame 637 to rotate towards the center of the bag-covering frame, so that the second clamping element 639 always adheres tightly to the packing bag 1 on the bag-covering frame, thus maintaining the clamping force on the packing bag 1. Specifically, the clamping assembly and two support assemblies are arranged circumferentially on the base 630, and the second clamping member 639 is located between the two support assemblies.

[0057] Optionally, the second clamping member 639 may include a fourth clamping plate, a fifth clamping plate, and a sixth clamping plate, which are sequentially connected to form a C-shaped structure. The angle between the fourth and fifth clamping plates is an obtuse angle, and the angle between the fifth and sixth clamping plates is also an obtuse angle. The fifth clamping plate is connected to the support frame 637. Preferably, to avoid damage to the packaged item 2 due to hard contact with it during clamping, a buffer block 70 can be provided on the side of the second clamping member 639 facing the packaged bag 1. The buffer block 70 can be made of rubber or sponge.

[0058] In some embodiments of this application, the automatic packaging system further includes a first scanning mechanism 8 and a second scanning mechanism. The first scanning mechanism 8 is used to identify a first identification code on the item 2 to be packaged on the first conveying mechanism 5, and the second scanning mechanism is used to identify a second identification code on the empty packaging bag 1 receiving the item 2. Specifically, as shown... Figure 6 As shown, the first scanning mechanism 8 includes a camera bracket located at the end of the first conveying mechanism 5 and an industrial camera mounted on the camera bracket. The industrial camera identifies the first identification code of the package 2 to be packaged on the first conveying mechanism 5. The second scanning mechanism is located below the end of the first conveying mechanism 5 and is used to identify the second identification code on the empty packaging bag 1 that will receive the package 2. The identified second identification code is associated with the first identification code in the background for easy management.

[0059] Optionally, both the first scanning mechanism 8 and the second scanning mechanism can be barcode scanners or RFID readers. For example, in the express delivery industry, small, regularly shaped express packages are typically called small parcels. These small parcels are centrally transported using bundled bags (bags 1). Small parcels within the same bundled bag have the same destination. Bundled bags from the same company have uniform size specifications and can circulate and be reused between different transit points. Each bundled bag is equipped with an RFID card as a second identification code, with each RFID card corresponding to an RFID number used to associate with the internal express packages. The second scanning mechanism is an RFID reader, which can identify the RFID cards on the bag 1. Each express package has a barcode (e.g., a one-dimensional or two-dimensional barcode) as a first identification code. The first scanning mechanism 8 is a barcode scanner, which can identify the barcode on the express package. The identified barcode is associated with the RFID number of the bundled bag in the background for easy management. During the transport process, the bundled bag's number and express delivery information are traceable and queryable in the logistics system.

[0060] The following example uses a package to be packaged as a courier item. Figure 6 The working principle of the automated packaging system shown is explained below:

[0061] After the parcels are sorted, they fall into the designated flow slots. When the number or volume of parcels in the slots reaches a certain level, the slots open automatically, unloading all the parcels into the first conveyor mechanism 5 to form a pile with a fixed flow direction. Parcels unloaded from different slots are distributed at a certain distance on the first conveyor mechanism 5 to distinguish them. When the parcels on the first conveyor mechanism 5 fall into the empty packing bag 1 located at the receiving station, the mounting plate 62 rotates 90° clockwise to send the received packing bag 1 to the sealing station. After the expansion and contraction mechanism of the automatic sealing device 3 clamps the opening of the packaged bag 1 at the sealing station, the expansion and contraction mechanism rotates and contracts to tighten the opening of the packaged bag 1. Then, the tie-sealing mechanism of the automatic sealing device 3 seals the tightened opening with tie 44. Then, the mounting plate 62 rotates 90° clockwise again to send the sealed packaged bag 1 to the transfer station. The handling robot 6 grabs the packaged bag 1 at the transfer station and places it on the second conveying mechanism 7. The second conveying mechanism 7 sends the sealed packaged bag 1 to the loading port.

[0062] In summary, the automatic packaging system provided in this application embodiment can realize automated packaging, which significantly improves the packaging speed compared to manual packaging, increases packaging efficiency, and saves manpower; it also shortens the process from sorting slots to packaging, avoiding problems such as jamming or damage of the items to be packaged in the equipment.
