Description

Technical Field

[0001] This invention relates to the field of food packaging technology, and in particular to a pickled mustard tuber packaging machine and method. Background Technology

[0002] In the field of food packaging automation, such as the packaging of pickled vegetables and preserved vegetables, it is necessary to separate and remove stacked composite film bags one by one in order to carry out subsequent filling and sealing processes. These bags are usually multi-layered composite structures containing aluminum foil or aluminized layers, have a certain degree of rigidity, and are usually arranged vertically and tightly in the storage tank.

[0003] In existing technologies, common single-sheet bag feeding devices often use a storage tank in conjunction with a pushing mechanism to press stacked vertically arranged packaging bags to the discharge port, and then use suction cups or grippers to adsorb the outermost packaging bag and pull it outwards to achieve bag feeding one by one.

[0004] However, when these rigid composite film packaging bags are tightly stacked and stored, their smooth surfaces often cause strong adhesion between the bags due to factors such as static electricity buildup, ambient humidity, or insufficient drying of printing ink. This interlayer adhesion causes adjacent packaging bags to stick together tightly, and when the suction cup adheres to the outermost packaging bag and pulls it outward, the second or even multiple bags stuck to it are easily pulled out simultaneously. Summary of the Invention

[0010] The lifting mechanism includes a U-shaped frame, two first guide rods, a connecting plate, and a fourth servo electric cylinder. The U-shaped frame is fixedly mounted on the top of the base; the two first guide rods are slidably mounted on the U-shaped frame and pass through the U-shaped frame; the connecting plate is fixedly mounted on the top of the two first guide rods and is fixedly connected to the first servo electric cylinder; the fourth servo electric cylinder is fixedly mounted on the U-shaped frame, and the output end of the fourth servo electric cylinder is fixedly connected to the connecting plate.

[0011] The swing mechanism includes two support plates, two connecting rods, and a servo motor.

[0012] The heat sealing mechanism includes a crossbeam, two second guide rods, a heat sealing block, and a fifth servo electric cylinder. The crossbeam is fixedly mounted on the support; the two second guide rods are slidably mounted on the crossbeam and pass through the crossbeam; the heat sealing block is fixedly mounted on one end of the two second guide rods; the fifth servo electric cylinder is fixedly mounted on the crossbeam, and the output end of the fifth servo electric cylinder is fixedly connected to the heat sealing block.

[0015] This invention also provides a method of using a pickled mustard tuber packaging machine, comprising the following steps: Several pickled mustard tuber packaging bags are arranged vertically in the storage tank, with one end of the bag row abutting against the end baffle. The feeding mechanism continuously presses the bag row towards the end baffle and pushes it intermittently. The lifting mechanism drives the first servo cylinder to a preset height. The first servo cylinder pushes the mounting base forward, so that the first suction cup at the top of the swing arm fits against the top of the outermost packaging bag at the discharge end of the storage tank; the first suction cup draws a vacuum to adsorb the top of the packaging bag. The second servo cylinder retracts, driving the swing arm to swing around the mounting base. The first suction cup causes the upper end of the attached packaging bag to bend backward, moving it away from the adjacent packaging bag behind, forming an opening between the first and second packaging bags. The swing mechanism drives the separating rod to move, and it enters the opening through the meshing opening on the side wall of the storage tank, so that the separating rod is stuck between the bent packaging bag and the adjacent packaging bag behind it, thus achieving physical separation; The second servo cylinder extends, driving the swing arm to swing and reset. The first suction cup drives the upper end of the bent packaging bag to return to a vertical position. The lifting mechanism works in conjunction with the first servo cylinder to move the outermost packaging bag, which has been separated by the separating rod, upward and remove it from the storage slot, thus completing the single-sheet extraction.

[0016] This invention discloses a pickled mustard tuber packaging machine and method. The storage slot is used to vertically store and arrange several composite film pickled mustard tuber packaging bags to be retrieved, and provides basic support for bag retrieval operations. A feeding mechanism is disposed on the storage slot, used to continuously push and press the packaging bags arranged in the storage slot towards the discharge end, ensuring that the outermost packaging bag is always in a fixed position that can be attracted. An end baffle is fixedly disposed at one end of the storage slot, serving as a limiting reference for the forward movement of the bag column, preventing the packaging bags from detaching from the discharge end, and cooperating with the feeding mechanism to form a front-to-back constraint on the entire row of packaging bags. A first servo electric cylinder is disposed at the top of the lifting mechanism, i.e., the overall lifting is achieved through the lifting mechanism. A mounting base is fixedly disposed at the output end of the first servo electric cylinder, so the mounting base can perform horizontal telescopic movement under the drive of the first servo electric cylinder. The bottom end of a swing arm is rotatably connected to the mounting base and located at the top of the mounting base, allowing the swing arm to swing around its bottom pivot. A first suction cup is fixedly disposed at the top end of the swing arm, used to attract the upper end of the outermost packaging bag. When the second servo cylinder extends or retracts, it drives the swing arm to swing around its bottom end, thereby causing the first suction cup to move in an arc, causing the upper end of the adsorbed packaging bag to bend or return to its original position. One end of the storage slot is provided with two engaging openings, which are located on both sides of the discharge end of the storage slot, allowing the separating rod to pass through. The swing mechanism is located on the top of the base, and the separating rod is mounted on the swing mechanism. Driven by the swing mechanism, the separating rod can swing in an arc, entering the gap between the bent and opened packaging bag and the adjacent packaging bag behind it through the engaging openings, achieving physical separation and preventing collapsing when removing the bag. When removing the bag, the first suction cup first adheres to the top of the outermost packaging bag. Then, the second servo cylinder retracts, driving the swing arm to swing backward, causing the first suction cup to bend the top of the adhered packaging bag backward. Because the packaging bag itself has a certain rigidity, the top bends relatively rigidly under the bending force, while its bottom is still constrained by the end baffle and the rear bag row. Therefore, a distinct V-shaped opening is forcibly formed between the upper parts of the first and second packaging bags. This bending action simultaneously breaks the interlayer adhesion force between the bags caused by static electricity, humidity, or ink. Next, the swing mechanism drives the separating rod through the engaging opening into this opening. After the separating rod engages, it forms a rigid physical barrier between the bent packaging bag and the adjacent rear packaging bag. Afterward, even if residual adhesion remains between the two bags, the rear packaging bag cannot cross the separating rod and follow the first bag. Then, the second servo cylinder extends to reset the swing arm, and the first suction cup drives the upper end of the packaging bag back to vertical. The lifting mechanism and the first servo cylinder then work together to remove the packaging bag upwards. Throughout the process, the feeding mechanism and the end baffle maintain constraint on the rear bag column, working together with the separating rod to ensure that only one packaging bag is removed at a time, thus solving the technical problem of overlapping bags during bag removal in existing technologies.

[0029] Furthermore, the storage slot 2 is fixedly disposed on the top of the base 1; the feeding mechanism 3 is disposed on the storage slot 2; the end baffle 4 is fixedly disposed on one end of the storage slot 2; the lifting mechanism 5 is disposed on the top of the base 1; the first servo cylinder 6 is disposed on the top of the lifting mechanism 5; the mounting base 7 is fixedly disposed on the output end of the first servo cylinder 6; the bottom end of the swing rod 8 is rotatably connected to the mounting base 7 and is located on the top of the mounting base 7; the top end of the swing rod 8 is fixedly disposed on the first suction cup 9; the cylinder end of the second servo cylinder 10 is rotatably connected to the mounting base 7, and the output end of the second servo cylinder 10 is rotatably connected to the swing rod 8; one end of the storage slot 2 is provided with two meshing openings 201; the swing mechanism 11 is disposed on the top of the base 1; and the separation rod 12 is disposed on the swing mechanism 11.

[0030] In this embodiment, the storage slot 2 is used to vertically store and arrange several composite film pickled mustard tuber packaging bags to be taken out, and to provide basic support for the bag taking operation. The feeding mechanism 3 is set on the storage slot 2, and is used to continuously push and press the packaging bags arranged in the storage slot 2 towards the discharge end, ensuring that the outermost packaging bag is always in a fixed position that can be attracted. The end baffle 4 is fixedly set at one end of the storage slot 2, serving as a limiting reference for the forward movement of the bag column, preventing the packaging bags from falling out of the discharge end, and cooperating with the feeding mechanism 3 to form front and back constraints on the entire row of packaging bags. The first servo electric cylinder 6 is set at the top of the lifting mechanism 5, that is, the overall lifting is achieved through the lifting mechanism 5. The mounting base 7 is fixedly set at the output end of the first servo electric cylinder 6, so the mounting base 7 can move horizontally and telescopically under the drive of the first servo electric cylinder 6. The bottom end of the swing rod 8 is rotatably connected to the mounting base 7 and is located at the top of the mounting base 7, so that the swing rod 8 can swing around its bottom pivot. The first suction cup 9 is fixedly installed at the top of the swing rod 8 for adsorbing the upper end of the outermost packaging bag. When the second servo cylinder 10 extends or retracts, it can drive the swing rod 8 to swing around its bottom end, thereby causing the first suction cup 9 to move in an arc, causing the upper end of the adsorbed packaging bag to bend or return to its original position. One end of the storage tank 2 is provided with two engaging openings 201, which are opened on both sides of the discharge end of the storage tank 2 for the separation rod 12 to pass through. The swing mechanism 11 is provided on the top of the base 1, and the separation rod 12 is provided on the swing mechanism 11. Driven by the swing mechanism 11, the separation rod 12 can swing in an arc, entering the gap between the bent and opened packaging bag and the adjacent packaging bag behind it through the engaging opening 201, realizing physical separation and preventing the bag from being pulled along when it is taken out. When removing the bag, the first suction cup 9 first adheres to the upper end of the outermost packaging bag. Then, the second servo cylinder 10 retracts, driving the swing rod 8 to swing backward, causing the first suction cup 9 to bend the upper end of the adhered packaging bag backward. Because the packaging bag itself has a certain rigidity, the upper end will warp in a relatively rigid manner after being bent by the bending force, while its lower end is still constrained by the end baffle 4 and the rear bag row. Therefore, a distinct V-shaped opening is forcibly formed between the upper halves of the first and second packaging bags. This bending action simultaneously breaks the interlayer adhesion force between the bags caused by static electricity, humidity, or ink. Next, the swing mechanism 11 drives the separating rod 12 through the engagement opening 201 into this opening. After the separating rod 12 engages, it forms a rigid physical barrier between the bent packaging bag and the adjacent rear packaging bag. Afterward, even if there is still residual adhesion between the two bags, the rear packaging bag cannot cross the separating rod 12 and follow the first bag. Then, the second servo cylinder 10 extends to reset the swing arm 8, and the first suction cup 9 drives the upper end of the packaging bag back to vertical. Then, the lifting mechanism 5 and the first servo cylinder 6 work together to remove the packaging bag upwards. Throughout the process, the feeding mechanism 3 and the end baffle 4 always maintain constraint on the rear bag column, working together with the separating rod 12 to ensure that only one packaging bag is removed at a time, thereby solving the technical problem of the simultaneous removal of bags in the prior art.

[0031] Furthermore, the support 13 is fixedly mounted on the top of the base 1; the third servo cylinder 14 is fixedly mounted on the support 13; the second suction cup 15 is fixedly mounted on the output end of the third servo cylinder 14; the filling device 16 is fixedly mounted on the top of the support 13; and the two heat sealing mechanisms 17 are mounted on the support 13.

[0032] In this embodiment, the support 13 is fixedly mounted on the top of the base 1, serving as the main support structure for the filling and sealing station. The third servo cylinder 14 is fixedly mounted on the support 13, and its output end is fixedly mounted with the second suction cup 15. When the packaging bag removed in the previous process is transferred to the support 13, the third servo cylinder 14 pushes the second suction cup 15 to extend, adsorbing the other side of the packaging bag, and cooperating with the first suction cup 9 to realize the bag opening operation. The filling device 16 is fixedly mounted on the top of the support 13, with its filling nozzle located directly above the bag opening station, used to quantitatively fill the packaging bag with pickled mustard tuber material after the first suction cup 9 and the second suction cup 15 open the bag opening. Two heat sealing mechanisms 17 are mounted on the support 13, located on both sides of the bag opening, used to clamp, heat, and pressurize the bag opening after filling to achieve a seal.

[0033] Furthermore, the conveyor belt 18 is fixedly mounted on the top of the base 1 and located below the filling device 16.

[0034] In this embodiment, after the packaging bag is filled and heat-sealed, the first suction cup 9 and the second suction cup 15 are released, and the packaged pickled mustard tuber packaging bag falls onto the conveyor belt 18 under the action of gravity, and is transported by the conveyor belt 18 to the next process or the finished product collection point.

[0035] Furthermore, the two displacement members 301 are respectively disposed on the side of the storage slot 2; each displacement member 301 is provided with a lifting member 302; the push plate 303 is disposed on the side of the lifting member 302 and located in the storage slot 2.

[0036] In this embodiment, two displacement members 301 are respectively disposed on the side of the storage slot 2, and can move along the length of the storage slot 2 to provide forward and backward power for the push plate 303. Each displacement member 301 is provided with a lifting member 302, and the push plate 303 is disposed on the side of the corresponding lifting member 302 and located in the storage slot 2. When the lifting member 302 is activated, it can drive the push plate 303 to rise and disengage or descend and insert within the storage slot 2.

[0037] Two push plates 303 are arranged one in front of the other in the storage slot 2, with a gap between them. There is also a gap between the front push plate 303 and the end baffle 4; initially, both gaps are the same. During operation, several packaging bags are vertically placed between the front push plate 303 and the end baffle 4, and bag retrieval can begin. The front push plate 303 continuously pushes the packaging bags towards the end baffle 4, while the rear push plate 303 moves forward synchronously, maintaining a constant gap between the two push plates 303. During this process, several more packaging bags can be added between the two push plates 303. When the front push plate 303 has pushed all the packaging bags in front of it to the end baffle 4, it rises directly under the drive of the corresponding lifting component 302, detaches from the storage slot 2, and is then driven back to the end away from the end baffle 4 by the corresponding displacement component 301. Finally, it descends under the drive of the lifting component 302 and re-inserts into the storage slot 2. At this time, the pusher plate 303 at the rear continues to push the remaining pile of packaging bags forward, taking over the forward feeding of bags. At the same time, a gap is formed again between the two pusher plates 303, and new packaging bags can be added into this gap, thereby achieving uninterrupted continuous bag feeding.

[0038] Furthermore, the U-shaped frame 501 is fixedly mounted on the top of the base 1; the two first guide rods 502 are slidably mounted on the U-shaped frame 501 and pass through the U-shaped frame 501; the connecting plate 503 is fixedly mounted on the top of the two first guide rods 502 and is fixedly connected to the first servo cylinder 6; the fourth servo cylinder 504 is fixedly mounted on the U-shaped frame 501, and the output end of the fourth servo cylinder 504 is fixedly connected to the connecting plate 503.

[0039] In this embodiment, the fourth servo cylinder 504 is fixedly mounted on the U-shaped frame 501, and its output end is fixedly connected to the connecting plate 503. When the fourth servo cylinder 504 extends or retracts, it drives the connecting plate 503 to move up and down along the two first guide rods 502. Ultimately, this drives the first suction cup 9 to rise and fall.

[0040] Furthermore, the two support plates 1101 are fixedly mounted on the top of the base 1; the bottom ends of the two connecting rods 1102 are rotatably connected to the two support plates 1101 respectively, and the top ends of the two connecting rods 1102 are fixedly connected to the two ends of the separating rod 12 respectively; the servo motor 1103 is fixedly mounted on one of the support plates 1101, and the output end of the servo motor 1103 is fixedly connected to the bottom end of one of the connecting rods 1102.

[0041] In this embodiment, the servo motor 1103 is fixedly mounted on one of the support plates 1101, and the output end of the servo motor 1103 is fixedly connected to the bottom end of one of the connecting rods 1102, for precisely controlling the swing angle of the connecting rod 1102, thereby driving the separating rod 12 to enter and exit the storage slot 2 through the engagement opening 201, and completing the insertion separation and retraction actions.

[0042] Furthermore, the crossbeam 1701 is fixedly mounted on the support 13; the two second guide rods 1702 are slidably mounted on the crossbeam 1701 and pass through the crossbeam 1701; the heat sealing block 1703 is fixedly mounted on one end of the two second guide rods 1702; the fifth servo electric cylinder 1704 is fixedly mounted on the crossbeam 1701, and the output end of the fifth servo electric cylinder 1704 is fixedly connected to the heat sealing block 1703.

[0043] In this embodiment, the heat-sealing block 1703 is fixedly disposed at one end of the two second guide rods 1702, and has a heating element inside for applying temperature and pressure to the opening of the packaging bag. The fifth servo electric cylinder 1704 is fixedly disposed on the crossbeam 1701, and its output end is fixedly connected to the heat-sealing block 1703. The two heat-sealing mechanisms 17 are respectively disposed on both sides of the opening of the packaging bag. When the two fifth servo electric cylinders 1704 synchronously drive the two heat-sealing blocks 1703 to close in the middle, the opening of the packaging bag can be clamped in the middle for heating and pressurizing heat sealing. After completion, they synchronously retract and release.

[0044] Furthermore, the slider 30101 is slidably disposed on the side of the storage slot 2; the lead screw 30102 is rotatably disposed on the side of the storage slot 2 and threadedly connected to the slider 30101; the motor 30103 is fixedly disposed at one end of the storage slot 2, and the output end of the motor 30103 is fixedly connected to the lead screw 30102.

[0045] In this embodiment, when the motor 30103 drives the lead screw 30102 to rotate, the slider 30101 moves back and forth along the side of the storage slot 2 through the threaded transmission, thereby driving the lifting component 302 and the push plate 303 to achieve precise displacement along the bag row pushing direction.

[0046] Furthermore, the third guide rod 30201 is slidably disposed on the slider 30101 and passes through the slider 30101; the top block 30202 is fixedly disposed on the top end of the third guide rod 30201 and is fixedly connected to the push plate 303; the sixth servo electric cylinder 30203 is fixedly disposed on the slider 30101, and the output end of the sixth servo electric cylinder 30203 is fixedly connected to the top block 30202.

[0047] In this embodiment, when the sixth servo electric cylinder 30203 extends or retracts, it drives the top block 30202 and the third guide rod 30201 to move in the vertical direction, causing the push plate 303 to rise and disengage from the storage slot 2 or descend and insert into the storage slot 2. This, in conjunction with the displacement member 301, enables the push plate 303 to retract, reset, and reconnect.

[0048] In this embodiment, a pickled mustard tuber packaging machine is used by vertically placing several packaging bags into the storage slot 2. The feeding mechanism 3 intermittently pushes and presses the bags towards the end baffle 4. When removing the bags, the lifting mechanism 5, in cooperation with the first servo cylinder 6, moves the first suction cup 9 to the top of the outermost packaging bag and adsorbs it. The second servo cylinder 10 retracts, driving the swing rod 8 to swing, causing the first suction cup 9 to bend the top of the packaging bag backward, forming an opening with the bag behind it. The swing mechanism 11 drives the separating rod 12 to enter the opening through the engagement opening 201, achieving physical separation. Subsequently, the second servo cylinder 10 extends, causing the swing rod 8 to return to its original position. The lifting mechanism 5, in cooperation with the first servo cylinder 6, lifts the packaging bag upward and moves it to the support 13. The third servo cylinder 14 pushes the second suction cup 15 to adhere to the other side of the packaging bag, and the first suction cup 9 and the second suction cup 15 move away from each other to open the bag opening, and the filling device 16 fills in the pickled mustard tuber; then the first suction cup 9 and the second suction cup 15 move closer to each other to close the bag opening, and the two heat sealing mechanisms 17 drive the heat sealing block 1703 to clamp the bag opening, heat and pressurize to complete the sealing, and after release, the finished product falls to the conveyor belt 18 and is sent out. It is important to note that both the first suction cup 9 and the second suction cup 15 are connected to an external vacuum source. The air path is switched via a solenoid valve to achieve the switching between suction and blowing. When a packaging bag needs to be adsorbed, the vacuum source provides negative pressure, and either the first suction cup 9 or the second suction cup 15 draws in air to generate suction force, firmly adhering to the surface of the packaging bag. When it is necessary to release the packaging bag or to quickly separate the packaging bag from the suction cup, the air path is switched to blow positive pressure gas into the suction cup. The airflow propulsion quickly detaches the packaging bag from the suction cup surface, avoiding adhesion and delay caused by residual vacuum, ensuring crisp and reliable actions in each stage of bag removal, opening, and finished product release.

[0049] The second embodiment of this application is as follows: Based on the first embodiment, please refer to Figure 8 ,in, Figure 8 This is a flowchart illustrating the second embodiment of the present invention.

[0050] The present invention provides a method for using a pickled mustard tuber packaging machine, comprising the following steps: S1: Several pickled mustard tuber packaging bags are vertically arranged in the storage tank 2, so that one end of the bag row abuts against the end baffle 4. The feeding mechanism 3 continuously presses the bag row towards the end baffle 4 and pushes it intermittently. S2: The lifting mechanism 5 drives the first servo cylinder 6 to a preset height. The first servo cylinder 6 pushes the mounting base 7 forward, so that the first suction cup 9 at the top of the swing arm 8 fits against the upper end of the outermost packaging bag at the discharge end of the storage slot 2; the first suction cup 9 draws a vacuum to adsorb the upper end of the packaging bag. S3: The second servo cylinder 10 retracts, driving the swing arm 8 to swing around the mounting base 7. The first suction cup 9 drives the upper end of the attached packaging bag to bend backward, making it away from the adjacent packaging bag behind, forming an opening between the first and second packaging bags. S4: The swing mechanism 11 drives the separating rod 12 to move, and enters the opening through the meshing opening 201 on the side wall of the storage groove 2, so that the separating rod 12 is stuck between the bent packaging bag and the adjacent packaging bag behind it, thus achieving physical separation. S5: The second servo cylinder 10 extends, driving the swing arm 8 to swing and reset. The first suction cup 9 drives the upper end of the bent packaging bag to return to a vertical position. The lifting mechanism 5 works in conjunction with the first servo cylinder 6 to move the outermost packaging bag, which has been separated by the separating rod 12, upward and remove it from the storage slot 2, thus completing the single-sheet extraction.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
