Description

Technical Field

[0001] This invention relates to the field of integrated weighing, packaging, and palletizing technology, specifically to a fully automated integrated weighing, packaging, and palletizing production line. Background Technology

[0002] Integrated weighing, packaging, and palletizing equipment is suitable for bagging, weighing, sewing, conveying, and palletizing of granular materials. It is commonly used in the packaging production of fertilizers and pet food pellets. To reduce the factory space occupied by the integrated palletizing production equipment, it usually uses two vertically aligned conveyors to package, unload, and palletize the materials. After the packaging scale automatically weighs, unloads, and sews the bags, when the bags move to the junction of the two conveyors, a bag-opening mechanism is used to reverse the conveying of the bags. The bottom of the vertically placed bags is pushed so that the bottom of the bags can move onto the conveyor belt of the second conveyor, thus completing the reversal of the bag conveying process.

[0003] If the overall weight of the packaging bag is large (over 20kg), and the granular material inside the bag has a certain degree of fluidity, causing the center of gravity of the bag to be at the bottom, a large pushing force is required when the bag-making mechanism pushes the bottom of the bag. However, the power device that applies the pushing force has a load capacity. When the weight of the packaging bag exceeds the load capacity of the power device, the bag-making mechanism cannot smoothly transfer the packaging bag to the conveyor belt of the second conveyor. Therefore, the bag-making mechanism is only suitable for transferring packaging bags within a certain weight range. If the weight of the packaging bag is large, the power source of the power device (electric push rod or geared motor) needs to be replaced, which will increase the equipment cost.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figures 1-8The diagram shows a fully automated weighing, packaging, and palletizing production line, comprising: a first conveyor frame 1, a second conveyor frame 4, and a third conveyor frame 6. The second conveyor frame 4 and the third conveyor frame 6 are fixedly connected, and the second conveyor frame 4 is perpendicular to the first conveyor frame 1, with the second conveyor frame 4 located between the first conveyor frame 1 and the third conveyor frame 6. The upper surface of the third conveyor frame 6 is higher than the upper surface of the first conveyor frame 1, and the second conveyor frame 4 is inclined. Two first rotating rollers 11 are rotatably mounted inside the first conveyor frame 1, and the two first rotating rollers 11 are positioned between... The transmission assembly is equipped with a first transmission belt 2. The interior of the second conveyor frame 4 is rotatably equipped with two second rollers 12, and a second transmission belt 5 is rotatably equipped between the two second rollers 12. The ends of adjacent first rollers 11 and second rollers 12 are fixedly equipped with bevel gears 13, and the two bevel gears 13 mesh with each other. The interior of the third conveyor frame 6 is rotatably equipped with several second transmission rollers 7 that are equidistantly distributed in a straight line. The outer wall of the first conveyor frame 1 is fixedly mounted with a motor 3, and the output end of the motor 3 is connected to the end of one of the first rollers 11 through a coupling.

[0030] It also includes a reversing unit for transferring the packaging bags conveyed on the first conveyor belt 2 to the second conveyor belt 5 for conveying. The reversing unit is located at the junction of the first conveyor frame 1 and the second conveyor frame 4.

[0031] The upper end face of the first conveyor frame 1 is provided with a stabilizing component, which includes two symmetrically distributed fixed frames 9 fixed to the upper end face of the first conveyor frame 1. The fixed frames 9 do not contact the first conveyor belt 2. Several rollers 10 distributed in a straight line are rotatably mounted on the end face of the two fixed frames 9 that are close to each other. After the packaging bag is placed on the first conveyor belt 2, the granules are filled, weighed, and sewn. Then, the first conveyor belt 2 transports the packaging bag to the position of the reversing unit. During the transport process, the side of the packaging bag rolls and contacts the rollers 10, thereby ensuring the stability of the packaging bag moving on the first conveyor belt 2.

[0032] The reversing unit includes a plurality of first transmission rollers 8 rotatably mounted inside the first conveyor frame 1, arranged in a straight line at equal intervals. The first transmission rollers 8 are located at the docking position of the first conveyor frame 1 and the second conveyor frame 4. Each first transmission roller 8 has a first synchronizing gear fixedly fitted at one end away from the second conveyor frame 4 and at the end of the first rotating roller 11 away from the bevel gear 13. A first synchronizing toothed belt is driven between the plurality of first synchronizing gears. A second synchronizing gear is fixedly fitted at one end of one of the plurality of second transmission rollers 7 and at the end of one of the second rotating rollers 12. A second synchronizing toothed belt is driven between the plurality of second synchronizing gears. The exterior of the first conveyor frame 1... A rotatable optical shaft 14 is mounted between the first conveyor frame 1 and the second conveyor frame 4. A lifting rod 15 is movably placed between two adjacent first conveyor rollers 8. One end of the lifting rod 15 is rotatably sleeved on the outside of the optical shaft 14. A right-angle plate 16 is fixedly mounted on the ends of several lifting rods 15 away from the optical shaft 14. A driving component is provided between the right-angle plate 16 and the second conveyor frame 4. When the packaging bag is conveyed above the first conveyor roller 8, it will be blocked by the right-angle plate 16. At this time, under the action of the driving component, the right-angle plate 16 can be rotated around the optical shaft 14, and the lifting rod 15 can transfer the packaging bag to the second conveyor belt 5.

[0033] The driving component includes a geared motor 18 fixed to the outer wall of the second conveyor frame 4, with a winding wheel fixedly mounted at the output end of the geared motor 18. A rotating sleeve 17 is rotatably mounted on the end of a right-angle plate 16 away from the first conveyor frame 1, and a rope 19 is fixedly mounted between the rotating sleeve 17 and the winding wheel. An arc-shaped rod 23 is fixedly mounted on the end of the right-angle plate 16 away from the first conveyor frame 1, and an arc-shaped sleeve 20 is slidably fitted on the other end of the arc-shaped rod 23. The end of the arc-shaped sleeve 20 away from the arc-shaped rod 23 is fixedly mounted to the first conveyor frame 1, and the end of the arc-shaped rod 23 extending into the arc-shaped sleeve 20 is fixedly mounted with a connecting rod. The slider 21 of the sliding assembly has a first spring 22 between the end of the slider 21 away from the arc rod 23 and the arc sleeve 20. Both ends of the arc sleeve 20 are provided with ventilation holes, which facilitate the normal sliding of the slider 21 inside the arc sleeve 20 without being subject to air resistance. When the reduction motor 18 drives the right angle plate 16 to flip by winding the rope 19, the arc rod 23 can be embedded inside the arc sleeve 20 and the first spring 22 can be compressed. When the reduction motor 18 drives the winding wheel to reverse, the reaction force generated by the first spring 22 can make the right angle plate 16 elastically return to its original position.

[0034] Several equidistant limiting strips 24 are fixedly provided on the outer surfaces of the first conveyor belt 2 and the second conveyor belt 5. The limiting strips 24 are made of rubber. The limiting strips 24 can increase the friction between the packaging bag and the first conveyor belt 2 and the second conveyor belt 5, thereby better transporting the packaging bag.

[0035] The outer surface of the second transmission roller 7 is fixedly provided with a number of friction elements 31 that are circumferentially distributed. The friction elements 31 are rubber bumps or friction particles. The friction elements 31 can improve the friction between the second transmission roller 7 and the packaging bag. The rubber bumps are made of flexible material, while the friction particles are made of hard material. The former can undergo elastic deformation.

[0036] Example 2: Please refer to Figures 6-8 This embodiment is a further explanation of other embodiments. A leveling unit is used to level the packaging bags filled with granules, facilitating the robotic arm's gripping and stacking of the bags. At least two leveling units are used, each located between two adjacent second conveyor rollers 7. The leveling units are distributed on the side of the third conveyor frame 6 closest to the second conveyor frame 4. Each leveling unit includes a base plate 25 fixed to the bottom of the third conveyor frame 6, and at least two retaining rods 26 are slidably mounted inside the base plate 25. The upper end face of each retaining rod 26 is fixed... A fixed-mounted paddle block 27 is provided, and a striking plate 29 is fixedly provided together among several paddle blocks 27. A second spring 28 is fixedly provided between each paddle block 27 and the base plate 25, and each second spring 28 is movably sleeved on the outside of the retaining rod 26. A paddle actuating component is also provided between the second transmission roller 7 and the paddle block 27. When the second transmission roller 7 rotates, the paddle block 27 can be pressed frequently and then released instantaneously by the paddle actuating component, so that the striking plate 29 can be elastically struck upward on the bottom of the packaging bag, and the packaging bag is flattened by the force of the strike.

[0037] The actuating component includes an annular groove 32 formed on the outer surface of the second transmission roller 7, and the number of annular grooves 32 is the same as the number of actuating blocks 27. A pawl 30 is fixedly arranged inside each annular groove 32. An extension rod is fixedly arranged on the outer surface of the actuating block 27, and the extension rod extends into the annular groove 32. When the second transmission roller 7 rotates with the pawl 30, the pawl 30 can press the actuating block 27 and the holding rod 26 down through the extension rod and release them instantly.

[0038] The upper surface of the striking plate 29 is curved, and the curved part of the striking plate 29 faces the first conveyor frame 1. When the packaging bag moves from the second conveyor frame 4 to the second conveyor roller 7, the striking plate 29 can be pressed down by the curved part of the striking plate 29.

[0039] When the second spring 28 is not compressed, the top of the striking plate 29 extends beyond the upper horizontal surface of the second transmission roller 7, thereby ensuring that when the striking plate 29 is released, the compressed second spring 28 can quickly return to its original position with the striking plate 29, thus elastically striking the bottom of the packaging bag.

[0040] Working principle: After adding sufficient granular product into the packaging bag and sewing it, the packaging bag moves to the top of the first conveyor roller 8 under the conveyor belt 2 until it is blocked by the right-angle plate 16. At this time, the rotation of the winding wheel is driven by the geared motor 18, which winds and pulls the rope 19 to make the right-angle plate 16 flip. During the flipping process, the packaging bag can be flipped by several lifting rods 15. The packaging bag will be inverted on the surface of the second conveyor belt 5. With the optical axis 14 as the fulcrum, the right-angle plate 16 is pulled by the winding of the geared motor 18 to make it flip. The method is similar to the lever principle, which can pry a heavy object with a small torque. Therefore, under the torque generated by the same model of geared motor 18, the weight range of the packaging bag flipping in this solution is larger and the applicability is stronger.

[0041] In this scheme, after the packaging bag is transferred from the upper end of the second conveyor belt 5 to the second conveyor roller 7, the packaging bag can press down on the striking plate 29. During the rotation of the second conveyor roller 7, the paddle 30 can frequently press the paddle block 27 and then release it instantly, so that the second spring 28 is compressed and then instantly rebounds to reset. When the striking plate 29 descends, it elastically resets upward and strikes the bottom of the packaging bag. The vibration generated by the striking is transmitted so that the particles inside the packaging bag are evenly distributed, avoiding the packaging bag being uneven. This would cause the packaging bag to fall from one side when the robot arm grabs the packaging bag, affecting the normal unloading and stacking of the packaging bag by the robot arm.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
