[0001] This invention relates to the field of fertilizer production technology, and in particular to an automatic fertilizer bag stacking line. Background Technology

[0002] In order to improve the production efficiency of automated production of chemical fertilizers or compound fertilizers, relevant research has emerged.

[0003] For example, Chinese invention patent application number CN202222573100.6, entitled "A Bag Pushing Device," includes a first conveying component, a second conveying component, and a pushing component. This device is equipped with a latching element, which forms an opening and a latching space. When pushing fertilizer bags, the bags are less likely to tilt, preventing them from falling outside the designated position and facilitating secondary conveying of the bags. Typically, fertilizer bags conveyed to the second conveying component still require manual handling and stacking, which is not only labor-intensive but also time-consuming and labor-intensive.

[0004] Therefore, there is an urgent need for an automatic fertilizer bag palletizing line to solve the problem that in the existing technology, fertilizer bags still need to be manually handled and palletized on the conveyor belt, which leads to high labor intensity and is time-consuming and labor-intensive for workers. Summary of the Invention

[0027] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0028] Please see Figure 1 This invention provides an automatic fertilizer bag palletizing line for palletizing bagged materials to a palletizing area. The line includes: a material conveyor belt 1, a pushing device 2, a flattening device 3, and a palletizing device 4. The material conveyor belt 1 has an inlet end and an outlet end. The pushing device 2 is positioned relative to the inlet end of the material conveyor belt 1 and is used to push the bagged materials onto the material conveyor belt 1. The flattening device 3 is positioned on the material conveyor belt 1 and is used to flatten the bagged materials. The palletizing device 4 includes a gripper 41 and a robotic arm 42. The gripper 41 is positioned above the material conveyor belt 1 and relative to the outlet end of the material conveyor belt 1, and is used to grip or release the bagged materials. The robotic arm 42 has a fixed end and a movable end. The fixed end of the robotic arm 42 is connected to the material conveyor belt 1, and the movable end is connected to the gripper 41, and is used to drive the bagged materials to be palletized to the palletizing area.

[0029] In this device, the material conveyor belt has an inlet end and an outlet end. The inlet end of the material conveyor belt is used to receive the bagged material pushed in by the pushing device 2 and to uniformly transport the bagged material to its outlet end. The flattening device 3 is set on the material conveyor belt to flatten the bagged material. The clamping claw 41 is set relative to the outlet end of the material conveyor belt and is connected to the movable end of the robotic arm 42 to clamp and release the bagged material. The movable end of the robotic arm 42 moves relative to its fixed end to drive the clamping claw 41 and the bagged material to be automatically stacked to the designated stacking area.

[0030] Compared to existing technologies, a flattening device is installed on the material conveyor belt to flatten the bagged material and control its thickness, making it easier for the bagged material to be automatically gripped. Then, a gripping claw 41 and a robotic arm 42 are installed above the discharge end of the material conveyor belt. The gripping claw 41 can automatically grip and release the bagged material. Driven by the robotic arm 42, the gripping claw 41 and the bagged material are automatically stacked to the designated stacking drive, thereby replacing manual handling and stacking, thus solving the technical problems of high labor intensity and time-consuming and labor-intensive work for workers.

[0031] Specifically, the material conveyor belt 1 and the pushing device 2 in this device are both common and readily available equipment on the market. The packaged bagged materials are pushed onto the material conveyor belt 1 by the pushing device 2. For reference, please refer to the Chinese invention patent with application number CN202222573100.6, entitled "A Bag Pushing Device". The material conveyor belt 1 and the pushing device 2 are conventional settings known to those skilled in the art, and will not be described in detail here.

[0032] Furthermore, the gripper 41 and the robotic arm 42 in this device are common and readily available equipment on the market. The gripper 41 can automatically grasp and release bagged materials, and the movable end of the robotic arm 42 can perform multiple degrees of freedom of movement relative to its fixed end to cooperate in completing the automatic palletizing of bagged materials. For details, please refer to the Chinese invention patent with application number CN201910010869.7 entitled: A Palletizing Robot Gripping Device for Bagged Goods. Here, the gripper 41 and the robotic arm 42 are conventional settings known to those skilled in the art, and will not be described in detail.

[0033] like Figure 1 , Figure 2 As shown, the device also includes a collection device 5, which is located at the discharge end of the material conveyor belt 1 and is used to collect scattered materials.

[0034] The collection device 5 is installed at the discharge end of the material conveyor belt 1 to collect materials that are accidentally scattered during the grabbing of bagged materials, so as to avoid material waste or reduce the labor intensity of workers collecting scattered materials.

[0035] like Figures 2 to 5 As shown, the flattening device 3 includes a support frame 31, a pressure roller 32, a first driving component 33, a connecting block 34, two sliding blocks 35, and two connecting rods 36.

[0036] The support frame 31 is mounted on the material conveyor belt 1 and has a hollow structure. The pressure roller 32 is positioned relative to the material conveyor belt 1 and is slidably connected to the support frame 31. A material passage gap is formed between the pressure roller 32 and the material conveyor belt 1. The first driving member 33, together with the support frame 31 and the pressure roller 32, is used to drive the pressure roller 32 to move closer to or further away from the material conveyor belt 1 to adjust the size of the material passage gap.

[0037] The movement of the first driving component 33 drives the pressure roller component 32 to move closer to or further away from the material conveyor belt 1, which is used to adjust the size of the material passage gap, so that the thickness of the bagged material can be adjusted, thereby facilitating the automatic gripping of the bagged material by the clamping claw 41.

[0038] One implementation method is, for example Figure 5As shown, the pressure roller component 32 includes a pressure roller block 321, multiple pressure roller shafts, and multiple pressure roller sleeves 323. The pressure roller block 321 is hinged to both connecting rods 36, and the pressure roller block 321 has a pressure roller groove relative to the material conveyor belt 1. The multiple pressure roller shafts are evenly arranged along the length direction of the pressure roller groove and are fixedly connected to the inner wall of the pressure roller groove. The pressure roller sleeves 323 are arranged in correspondence with the pressure roller shafts and are rotatably sleeved on the pressure roller shafts.

[0039] The pressure roller sleeve 323 is rotatably sleeved on the pressure roller shaft and is set relative to the material conveyor belt 1, so that the bagged material can be flattened by the pressure roller sleeve 323 when passing through the material passage gap.

[0040] As another implementation method, such as Figure 5 As shown, the connecting block 34 is connected to the support frame 31 and has a guide groove along its length. Two sliding blocks 35 are spaced apart and are slidably connected to the guide groove. The connecting rod 36 is arranged in a one-to-one correspondence with the sliding block 35. One end of the connecting rod 36 is hinged to the sliding block 35 and the other end is hinged to the pressure roller 32. The fixed end of the first driving member 33 is connected to one sliding block 35 and the extended end is connected to another sliding block 35, which is used to drive the two sliding blocks 35 to move closer or further away from each other.

[0041] Driven by the first driving member 33, the two spaced sliding blocks 35 can slide closer to or further away from each other. After sliding, the sliding blocks 35 drive the connecting rod 36 to move, and cause the pressure roller block 321 to move closer to or further away from the material conveyor belt 1.

[0042] One preferred implementation method is, for example... Figure 5 As shown, a sliding block 35 has a rotating hole, and another sliding block 35 has a first threaded hole opposite to the rotating hole. The first threaded hole passes through the other sliding block 35. The first driving member 33 includes a rotating block 331 and a first screw 332. The rotating block 331 is rotatably connected to a sliding block 35, and one end of the first screw 332 is threaded to the first threaded hole and connected to the rotating block 331.

[0043] The two sliding blocks 35, the rotating block 331 and the first screw 332 form a structure similar to a ball screw nut pair. The first screw 332 can rotate around its axis to drive the two spaced sliding blocks 35 to slide closer or further apart.

[0044] Furthermore, the first screw 332 can be driven to rotate around its axis manually or by a motor, which will not be elaborated further here.

[0045] like Figure 6 As shown, the collection device 5 includes a collection bin 51 and at least one guide plate 52, a plurality of first rotating shafts 53 and a plurality of arc-shaped blocks 54, and at least one elastic part 55.

[0046] Among them, the top of the collection bin 51 is open and in a "C" shape. The collection bin 51 cooperates to wrap around the periphery of the discharge end of the material conveyor belt 1 and is detachably connected to the material conveyor belt 1. The material guiding plate 52 is arranged obliquely downward and is connected to the inner wall of the collection bin 51.

[0047] The collection bin 51 in a "C" shape wraps around the periphery of the discharge end of the material conveyor belt 1 to collect the materials that accidentally scatter during the grasping process. At least one material guiding plate 52 is arranged obliquely downward to guide the materials to slide into the collection bin 51.

[0048] Among them, as an implementation manner, such as Figure 6 As shown, at least one arc-shaped groove is provided on the inner walls of the opposite sides of the collection bin 51. One end of the first rotating shaft 53 is respectively rotatably connected to the inner walls of the opposite sides of the collection bin 51, and the other ends are both connected to the two sides of one end of the material guiding plate 52. The arc-shaped blocks 54 are arranged corresponding to the arc-shaped grooves one by one, and one end of the arc-shaped block 54 is slidably embedded in the arc-shaped groove and the other end is connected to the other end of the material guiding plate 52.

[0049] The material guiding plate 52 is connected to the collection bin 51 through the first rotating shaft 53 and the arc-shaped blocks 54, so that the inclination angle of the material guiding plate 52 can be adjusted, which is beneficial to the collection of materials.

[0050] Among them, as another implementation manner, such as Figure 6 As shown, the elastic part 55 is arranged along the guide of the arc-shaped groove and is built in the arc-shaped groove. One end of the elastic part 55 is connected to the arc-shaped block 54 and the other end is connected to the bottom inner wall of the arc-shaped groove.

[0051] The setting of the elastic part 55 enables the material guiding plate 52 to slide along the direction close to the bottom of the arc-shaped groove when the materials scatter on the material guiding plate 52, so that the inclination angle of the material guiding plate 52 increases, which is beneficial to the collection of materials. At the same time, when the materials completely slide down, under the action of the elastic restoring force of the elastic part 55, the inclination angle of the material guiding plate 52 can be automatically reset, so as to reduce the entry of dust or impurities into the collection bin 51.

[0052] Among them, as a preferred implementation manner, such as Figure 6 As shown, the number of the material guiding plates 52 in the collection device 5 is multiple. The multiple material guiding plates 52 are arranged staggeredly along the height direction of the collection bin 51 and are all connected to the collection bin 51.

[0053] The multiple material guiding plates 52 are arranged staggeredly along the height direction of the collection bin 51, which can effectively guide the materials to fall into the collection bin 51, so as to better avoid and reduce the entry of dust or impurities into the collection bin 51.

[0054] In the specific workflow of this invention, the material conveyor belt has an inlet end and an outlet end. The inlet end of the material conveyor belt is used to receive the bagged material pushed in by the pushing device 2 and to uniformly transport the bagged material to its outlet end. The flattening device 3 is set on the material conveyor belt to flatten the bagged material. The clamping claw 41 is set relative to the outlet end of the material conveyor belt and is connected to the movable end of the robotic arm 42 to clamp and release the bagged material. The movable end of the robotic arm 42 moves relative to its fixed end to drive the clamping claw 41 and the bagged material to be automatically stacked to the designated stacking area. Compared to existing technologies, a flattening device is installed on the material conveyor belt to flatten the bagged material and control its thickness, making it easier for the bagged material to be automatically gripped. Then, a gripping claw 41 and a robotic arm 42 are installed above the discharge end of the material conveyor belt. The gripping claw 41 can automatically grip and release the bagged material. Driven by the robotic arm 42, the gripping claw 41 and the bagged material are automatically stacked to the designated stacking drive, thereby replacing manual handling and stacking, thus solving the technical problems of high labor intensity and time-consuming and labor-intensive work for workers.

[0055] In use, the bagged and sealed material is placed on the bag pushing device and pushed to the feed end of the material conveyor belt. When the bagged material passes through the flattening device, the pressure roller sleeve 323 flattens the surface of the bagged material and continues to transport the bagged material to its discharge end. The clamping claw 41 automatically grabs the material and, driven by the robotic arm 42, automatically stacks it to the designated stacking area.

[0056] Furthermore, when the bagged material is accidentally broken and spills during the gripping process by the gripper 41, the spilled material can be automatically collected into the collection bin 51 under the guidance of the guide plate 52 for secondary use. This not only reduces material waste but also reduces the labor intensity of workers collecting the material.

[0057] This device, through the aforementioned structure, can solve the technical problem in the prior art where fertilizer bags on the conveyor belt still require manual handling and stacking, resulting in high labor intensity and time-consuming work for workers.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
