[0017] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the technical solutions of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the described embodiments are merely some embodiments of this application, not all embodiments.

Furthermore, unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).

[0021] In the existing packaging process, workers need to participate multiple times: workers manually open the opening of the woven bag and then fill a certain amount of material into the woven bag; the woven bag containing the material is transported to the sewing machine by a conveyor belt; workers manually close the opening of the bag and then the sewing machine seals the woven bag.

[0022] The fully automatic bagging and sewing machine proposed in this embodiment can automate the packaging process, effectively improve packaging efficiency, and reduce workload.

[0023] like Figure 1 and Figure 2 As shown, this embodiment proposes a fully automatic bag-sewing machine, including: A bag storage device 100 is used to store packaging bags 10 to be filled with materials; The bag-picking device 200 is used to pick up the packaging bag 10 that is in the waiting position on the bag storage device 100 and open the bag opening of the packaging bag 10. The filling device 300 is used to fill the packaging bag 10 with materials through the bag opening of the packaging bag 10; Conveying device 400, used for conveying packaging bags 10 already loaded with materials; Sewing device 500 is used to sew the opening of packaging bag 10.

[0024] like Figure 3 As shown, the bag storage device 100 includes a shelf 110, which includes a storage cavity 111 for storing the packaging bag 10.

[0025] The storage compartment 111 includes a pre-storage position and a waiting position. The shelf 110 is equipped with a pushing device, which is used to push the packaging bag 10 in the pre-storage position to the waiting position. Figure 3 In the diagram, packaging bag 10 at position A is in the pre-storage position, and packaging bag 10 at position B is in the waiting position.

[0026] The bag storage device 100 is a dual-station bag storage platform. During the preparation stage, the packaging bags 10 are placed in the pre-storage position by manual labor or a robotic arm. Then, the packaging bags 10 in the pre-storage position are pushed to the waiting position by the pushing device, at which point the pre-storage position is empty. The pushing device returns to the initial state, and then a certain number of packaging bags 10 are placed in the pre-storage position. When the packaging bags 10 in the waiting position are emptied, the pushing device can directly push the packaging bags 10 in the pre-storage position to the waiting position, thereby effectively improving the overall operating efficiency of the equipment.

[0027] The pushing device includes a pushing cylinder 121 and a pushing arm 122, the pushing arm 122 being connected to the piston of the pushing cylinder 121. Multiple pushing arms 122 may be provided, and each pushing arm 122 may be connected to a connecting rod 246, which is also connected to the piston of the pushing cylinder 121.

[0028] The bag-taking device 200 is installed on the first frame 610.

[0029] like Figure 4 As shown, the bag-picking device 200 includes a bag-picking mechanism 210, a bag-feeding mechanism 220, an opening mechanism 230, and a transfer mechanism 240.

[0030] The bag-picking mechanism 210 is used to pick up the packaging bag 10 that is in the waiting position and place the picked-up packaging bag 10 on the bag-feeding mechanism 220; The bag feeding mechanism 220 is used to convey the packaging bag 10 to the opening mechanism 230; The opening mechanism 230 is used to open the opening of the packaging bag 10; The transfer mechanism 240 is used to transfer the packaged bag 10 with the opening to the filling device 300.

[0031] In this embodiment, the bag-picking mechanism 210 includes a first linear drive module 211 and a mounting arm 212. The first linear drive module 211 is used to drive the mounting arm 212 to move in a direction parallel to the x-axis. A bag-picking suction cup 213 is provided on the mounting arm 212. The first linear drive module 211 may be a ball screw mechanism.

[0032] The bag-picking suction cup 213 is connected to the corresponding vacuum pump via a corresponding pipeline. When the vacuum pump is started, the bag-picking suction cup 213 generates negative pressure to adsorb the packaging bag 10. The mounting arm 212 can be a hollow tube, and the bag-picking suction cup 213 is connected to the inner cavity of the mounting arm 212. The pipeline can be directly connected to the connector on the mounting arm 212.

[0033] Furthermore, a lifting cylinder 214 is mounted on the first linear drive module 211, and the mounting arm 212 is fixed to the piston of the lifting cylinder 214. Specifically, the first linear drive module 211 is used to directly drive the lifting cylinder 214 so that the mounting arm 212 moves in a direction parallel to the x-axis. When picking up the packaging bag 10, the lifting cylinder 214 controls the mounting arm 212 to descend, so that the bag-picking suction cup 213 comes into contact with the packaging bag 10; the bag-picking suction cup 213 adsorbs the packaging bag 10; the lifting cylinder 214 controls the mounting arm 212 to rise; the first linear drive module 211 drives the lifting cylinder 214 to move, thereby moving the packaging bag 10 adsorbed by the bag-picking suction cup 213 to above the bag-feeding mechanism 220; the lifting cylinder 214 controls the mounting arm 212 to descend, the bag-picking suction cup 213 releases its adsorption on the packaging bag 10, and thus the packaging bag 10 is placed on the bag-feeding mechanism 220.

[0034] The bag feeding mechanism 220 includes a conveyor belt, which drives the packaging bag 10 to move in a direction parallel to the y-axis, thereby conveying the packaging bag 10 to the position corresponding to the opening mechanism 230, so that the opening of the packaging bag 10 is aligned with the opening mechanism 230.

[0035] The opening mechanism 230 includes a second linear drive module 231 and a connecting seat 232. The second linear drive module 231 drives the connecting seat 232 to move in a direction parallel to the z-axis. The connecting seat 232 is equipped with an opening suction cup 233. The opening suction cup 233 is connected to a corresponding vacuum pump via a corresponding pipeline. The second linear drive module 231 can be a cylinder, and the connecting seat 232 is connected to the piston of the cylinder.

[0036] There are two opening mechanisms 230, which are placed on the upper and lower sides of the conveyor belt respectively, to correspond to the upper and lower surfaces of the bag opening of the packaging bag 10.

[0037] When the opening of the packaging bag 10 is opened, the second linear drive module 231 drives the connecting seat 232 to move toward the packaging bag 10, and makes the opening suction cup 233 fit against the outer surface of the opening of the packaging bag 10; then, the vacuum pump connected to the opening suction cup 233 is started, so that the opening suction cup 233 adsorbs the opening of the bag; the second linear drive module 231 drives the connecting seat 232 to move away from the packaging bag 10, thereby opening the opening of the packaging bag 10.

[0038] The x-axis, y-axis, and z-axis are perpendicular to each other. The z-axis is parallel to the vertical direction.

[0039] The transfer mechanism 240 includes a rotary drive module 241, a swing arm 242, and a bag-picking mechanism mounted on the swing arm 242. The rotary drive module 241 includes a motor.

[0040] The rotary drive module 241 drives the swing arm 242 to rotate, causing the bag-picking differential to rotate to the initial position, the bag-feeding position, and the separation position. The rotation axis of the swing arm 242 is parallel to the x-axis, and the initial position, bag-feeding position, and separation position are sequentially distributed along a preset direction. The bag-picking differential is initially in the initial position. As the swing arm 242 rotates in the same direction, the bag-picking differential will sequentially pass through the bag-feeding position and the separation position.

[0041] In this embodiment, the swing arm 242 needs to rotate 80-90° from the initial position to the bag feeding position; and 5-10° from the bag feeding position to the separation position. The initial position is located below the bag feeding position, and the bag feeding position is located below the separation position. Figure 4 In the middle, the bag taking and dispensing differential is in the bag delivery position.

[0042] The bag-removing mechanism includes a first component arm 2431 and a second component arm 2432 arranged at intervals. One end of each of the first component arm 2431 and the second component arm 2432 is rotatably connected to the swing arm 242, and the other end of each is provided with a plug 2433 for opening the bag opening of the packaging bag 10. Figure 4 In the middle, plug 2433 is inserted into the bag opening.

[0043] An adjustment module 244 is provided between the first component arm 2431 and the second component arm 2432. The adjustment module 244 is used to drive the first component arm 2431 and the second component arm 2432 to rotate about the swing arm 242, so as to adjust the distance between the plugs 2433 of the first component arm 2431 and the plugs 2433 of the second component arm 2432. When the first component arm 2431 and the second component arm 2432 rotate about the swing arm 242, the rotation axes of both are parallel to the z-axis.

[0044] The adjustment module 244 may be a cylinder, wherein the main body of the cylinder is rotatably connected to the first component arm 2431, and the piston of the cylinder is rotatably connected to the second component arm 2432.

[0045] Furthermore, an extension arm 245 is provided on the side of the second component arm 2432 near the swing arm 242, extending away from the plug 2433. A connecting rod 246 is provided at the end of the extension arm 245, with one end rotatably connected to the extension arm 245 and the other end rotatably connected to the first component arm 2431. Thus, when the adjustment module 244 is activated, the first component arm 2431 and the second component arm 2432 rotate in opposite directions, causing the plugs 2433 of both the first and second component arms 2431 to move closer to or further away from each other.

[0046] In this embodiment, when the bag-removing mechanism is in the initial position, the plug 2433 is opposite to the opening of the packaging bag 10. At this time, the adjustment module 244 controls the increase of the distance between the plugs 2433 of the first component arm 2431 and the plugs 2433 of the second component arm 2432 to tighten the opening of the packaging bag 10. In the initial state, the distance between the plugs 2433 of the first component arm 2431 and the plugs 2433 of the second component arm 2432 is less than a certain size to ensure that both plugs 2433 can be inserted into the bag opening.

[0047] When the bag picker is in the bag feeding position, the packaging bag 10 is transferred to the filling device 300. As the swing arm 242 rotates, the bag picker moves from the initial position to the bag feeding position. During this process, the bag opening of the packaging bag 10 is held in place by the two plugs 2433, so the packaging bag 10 will rotate accordingly. When the bag picker is in the bag feeding position, the bag opening of the packaging bag 10 is vertically upward.

[0048] When the bag-picking mechanism is in the separation position, the plug 2433 separates from the packaging bag 10. After the packaging bag 10 is transferred to the filling device 300, the packaging bag 10 is fixed by the filling device 300. During the process of the bag-picking mechanism moving from the bag feeding position to the separation position, the plug 2433 rotates in the direction away from the bag opening, thus separating the plug 2433 from the bag opening. Subsequently, the adjustment module 244 adjusts the second component arm 2432 of the first component arm 2431 to increase the distance between the plugs 2433 until it is greater than the width of the bag opening (to avoid interference between the plug 2433 and the packaging bag 10 in subsequent operations). Then, the rotation drive module 241 controls the bag-picking mechanism to rotate in the opposite direction until it returns to the initial position. The adjustment module 244 adjusts the first component arm 2431 and the second component arm 2432 to restore the distance between the plugs 2433 to the initial state, thus preparing for the next bag picking.

[0049] like Figures 5-8 As shown, the loading device 300 includes a hopper 310, a fixing mechanism 320, and a support mechanism 330. The loading device 300 is mounted on a mounting frame 301.

[0050] The inside of the hopper 310 is used to store materials. Before each material is put into the hopper 310, the material can be weighed in advance, and then the material of the corresponding weight can be placed into the hopper 310 for loading. This ensures that the weight of the material loaded each time meets the requirements.

[0051] The bottom of the hopper 310 is provided with an openable hopper gate 311, which is rotatably connected to the hopper 310. The fixing mechanism 320 is used to keep the inner wall of the bag opening of the packaging bag 10 in contact with and relatively fixed to the outer wall of the hopper gate 311. The corner support mechanism 330 is used to insert into the bag opening of the packaging bag 10 and support the corners of the packaging bag 10.

[0052] There are two sets of fixing mechanisms 320 arranged symmetrically. The fixing mechanism 320 includes a clamping block 321 and two bag clamping cylinders 322. The main body of the bag clamping cylinder 322 is rotatably connected to the mounting frame 301, and the piston is rotatably connected to the clamping block 321. The clamping block 321 is also rotatably connected to the corresponding hopper door 311.

[0053] There are two gates 311, and each gate 311 is connected to a switching mechanism, with each switching mechanism corresponding to one gate 311. The switching mechanism includes a switching cylinder 312. The main body of the switching cylinder 312 is rotatably connected to the mounting bracket 301, and its piston is rotatably connected to the corresponding gate 311.

[0054] There are two symmetrically arranged corner support mechanisms 330. Each corner support mechanism 330 includes a corner support cylinder 331, a fixed arm 332, a first connecting rod 333, a second connecting rod 334, and a corner support member 335. The corner support member 335 includes a first component 3351, a second component 3352, and a third component 3353 connected in sequence, wherein the connection between the first component 3351 and the second component 3352 is a connecting part. The fixed arm 332 is fixed to the mounting bracket 301; one end of the first connecting rod 333 is rotatably connected to the fixed arm 332, and the other end is rotatably connected to the connecting part; one end of the second connecting rod 334 is rotatably connected to the fixed arm 332, and the other end is rotatably connected to the first component 3351; the third component 3353 is used to insert into the bag opening and abuts against the corner of the bag opening; the main body of the corner support cylinder 331 is rotatably mounted on the fixed arm 332, and the piston is rotatably connected to the middle part of the first connecting rod 333. The bag opening is tightened by the two support mechanisms 330.

[0055] The bag-removing mechanism places the open packaging bag 10 onto the hopper gate 311; the fixing mechanism 320 activates and drives the clamping block 321 to rotate downwards, tightly pressing the packaging bag 10 onto the hopper gate 311; the switching mechanism activates and opens the hopper gate 311, thereby further expanding the opening of the bag; the corner support mechanism 330 activates, and the third component 3353 of the corner support mechanism 330 inserts into the opening of the packaging bag 10 and opens the bag corners; the material in the hopper 310 falls into the packaging bag 10, completing the material loading; the switching mechanism activates and closes the hopper gate 311; the corner support mechanism 330 activates, and the third component 3353 of the corner support mechanism 330 retracts and moves out of the bag opening; the fixing mechanism 320 activates and drives the clamping block 321 to rotate upwards, thereby separating it from the packaging bag 10.

[0056] like Figure 5 As shown, the conveying device 400 includes a handling mechanism. The handling mechanism is used to handle the packaging bags 10 that are already loaded with materials.

[0057] The handling mechanism includes two symmetrically arranged handling modules 410. Each handling module 410 includes a support 411 and a third linear drive module 412. A support module is mounted on the support 411. The support module carries the packaging bag 10. The third linear drive module 412 drives the support 411 to move in a direction parallel to the x-axis, causing the support module to move to a first position or a second position. The first position is below the filling device 300, and the second position is below the sewing device 500.

[0058] The third linear drive module 412 can adopt a lead screw and nut mechanism. The structure of the sewing device 500 can refer to existing sewing machines, and will not be described in detail here.

[0059] The support module includes a tray 413, a fourth linear drive module 414, and a lifting drive module 415. The tray 413 is connected to the fourth linear drive module 414, and the fourth linear drive module 414 is mounted on the lifting drive module 415. The lifting drive module 415 is used to drive the fourth linear drive module 414 to move in a direction parallel to the z-axis, so that the tray 413 rises or falls. The fourth linear drive module 414 is used to drive the tray 413 to move in a direction parallel to the y-axis.

[0060] The x-axis, y-axis, and z-axis are perpendicular to each other. The z-axis is parallel to the vertical direction.

[0061] Both the fourth linear drive module 414 and the lifting drive module 415 can be cylinders.

[0062] The bracket 411 is equipped with a clamping module and an abutment module. The clamping module is used to clamp the opening of the packaging bag 10, and the abutment module is used to abut the side of the packaging bag 10.

[0063] The clamping module includes a clamping cylinder 421 and a clamping plate 422, with the piston of the clamping cylinder 421 connected to the clamping plate 422. The abutting module includes an abutting cylinder 431 and an abutting plate 432, with the piston of the abutting cylinder 431 connected to the abutting plate 432.

[0064] Since there are two transport modules 410, there are also two clamping modules and two abutment modules. Thus, the two clamping plates 422 can clamp the bag opening to facilitate the sewing device 500 to sew the bag opening; the two abutment plates 432 can abut and hold the packaging bag 10 to ensure the stability of the packaging bag 10 during transport and prevent it from tipping over.

[0065] The conveying device 400 also includes a bag transfer mechanism 440, which is located below the pallet 413 and directly below the sewing device 500. The bag transfer mechanism 440 receives the packaging bags 10 from the handling modules 410. Two handling modules 410 are symmetrically arranged on both sides of the bag transfer mechanism 440 in the width direction, which is parallel to the y-axis.

The bag pushing module includes a bag pushing cylinder 451 and a push plate 452, wherein the push plate 452 is connected to the piston of the bag pushing cylinder 451.

[0067] The third linear drive module 412 pre-controls the support module to move below the filling device 300; the lifting drive module 415 controls the pallet 413 to rise; the fourth linear drive module 414 controls the pallet 413 to move directly below the packaging bag 10 on the filling device 300 to support the packaging bag 10; after the material is bagged, the packaging bag 10 separates from the filling device 300. At this time, the packaging bag 10 is supported by the pallet 413; the lifting drive module 415 controls the pallet 413 to descend to a preset height, and the packaging bag 10 descends synchronously with the pallet 413. The clamping module 422 clamps the bag opening; the abutment module 432 clamps the packaging bag 10; the third linear drive module 412 drives the bracket 411 to move toward the second position, thereby moving the packaging bag 10 below the sewing device 500; the sewing device 500 sews the bag opening; after the bag opening is sealed, the clamping module releases the bag opening, and the abutment module releases the packaging bag 10; the fourth linear drive module 414 controls the pallet 413 to move, so that the pallet 413 moves horizontally from directly above the bag transfer mechanism 440 to the side above the bag transfer mechanism 440. Figure 5In this process, the pallet 413 is located above the side of the bag transfer mechanism 440. Thus, the packaging bag 10 falls onto the bag transfer mechanism 440 under the action of gravity. The transmission mechanism transports the packaging bag 10 to the side corresponding to the push module. The push module is activated, the push plate 452 moves toward the packaging bag 10, and pushes the packaging bag 10 off the bag transfer mechanism 440.
