Description

Technical Field

[0001] This utility model relates to the field of bagged material packaging vehicle technology, and in particular to a palletizing device and a loading machine. Background Technology

[0002] Currently, most cement plants still use manual loading methods when loading bagged cement onto trucks. This method suffers from drawbacks such as high labor intensity and low loading efficiency. Some cement plants use semi-automatic loading machines. These machines typically include guide rails fixed to the plant building, a horizontal conveyor mounted on the guide rails, a traveling device mounted on the guide rails and connected to the output end of the horizontal conveyor, and an inclined conveyor. One end of the inclined conveyor is connected to the output end of the horizontal conveyor, and the other end is suspended from the traveling device by a steel wire rope.

[0003] The semi-automatic loading machine operates as follows: First, the walking device moves the output end of the inclined conveyor to the loading position. Then, the horizontal and inclined conveyors are activated to transport the bagged cement to the output end of the inclined conveyor. Next, workers transfer the bagged cement from the inclined conveyor to the vehicle, completing a multi-layer stack. After completing one stack, the walking device moves the output end of the inclined conveyor to the next stacking position, and the stacking continues in a cycle. During the stacking process, when the height of the inclined conveyor's output end needs to be raised, the height is adjusted by pulling a steel cable. This semi-automatic loading machine has the following problems in actual use: the labor intensity for workers is still relatively high, the loading efficiency is still low, and the working environment for workers is very harsh, which is detrimental to their health.

[0004] In view of this, Chinese Patent (CN205953049U) proposes a palletizing device for a bagged cement loading and palletizing host, disclosing a palletizing device for a bagged cement loading and palletizing host, including a mounting frame, on which a forward palletizing gate is provided, the forward palletizing gate including a palletizing gate cylinder mounted on the mounting frame, a connecting rod connected in the middle to the telescopic end of the palletizing gate cylinder, two intermediate connecting rods, two palletizing rotating rods, and two palletizing gate panels respectively hinged on one side to the mounting frame, one end of the palletizing rotating rod being fixedly connected to the palletizing gate panel, the other end of the palletizing rotating rod being hinged to one end of the intermediate connecting rod, and the other end of the intermediate connecting rod being hinged to the end of the connecting rod, the mounting frame having a forward baffle for longitudinal guidance of the bagged cement at the position corresponding to the position of the palletizing gate panel, and a lateral baffle for lateral guidance of the bagged cement on the outer side of the palletizing gate panel. However, this type of palletizing device can only move along the palletizing direction, and the types of pallets it can stack are limited, making it less applicable.

[0005] In view of this, the present invention proposes a palletizing device and a loading machine to improve the applicability of the loading machine. Utility Model Content

[0012] Optionally, the palletizing lifting drive device includes a palletizing lifting motor, a palletizing lifting reducer, a palletizing lifting gear, and a palletizing lifting rack. The output end of the palletizing lifting motor is connected to the input end of the palletizing lifting reducer, and the output end of the palletizing lifting reducer is connected to the palletizing lifting gear. The palletizing lifting gear meshes with the palletizing lifting rack, and the palletizing lifting rack is fixedly connected to the palletizing bracket. A palletizing guide post is fixed on the palletizing bracket, and a palletizing guide sleeve is provided on the palletizing frame.

[0015] The palletizing device and loading machine provided by this utility model have the following beneficial effects:

[0016] The gate drive device drives the gate slider to rise and fall in a predetermined direction, thereby driving the gate linkage to move. The gate linkage then drives the gate crank to rotate relative to the gate's drive shaft, which in turn drives the gate plate to rotate. This achieves synchronous rotation of the two gate plates, allowing the two gates to lift or release the material bags, thus achieving the purpose of palletizing. Since the palletizing rotation drive device is mounted on the palletizing bracket, and the gate bracket is rotatably mounted on the palletizing bracket, with the output end of the palletizing rotation drive device connected to the gate bracket, the gate can rotate 360° under the drive of the palletizing rotation drive device. This allows for the stacking of material bags with different patterns, such as five-patterned or six-patterned stacks, thus increasing the applicability of the palletizing device.

Figure 5 This is a structural schematic diagram of the palletizing device 300 from another perspective in Embodiment 1 of this utility model. Figure 6 This is a top view of the palletizing device 300 in Embodiment 1 of this utility model. Figure 7This is a front view structural schematic diagram of the palletizing device 300 in Embodiment 1 of this utility model. This embodiment provides a palletizing device 300, including a palletizing bracket 310, a palletizing rotation drive device 370, a gate bracket 320, a gate drive device 330, a gate slider 340, two gate transmission assemblies 350, and two gate plates 360. The gate transmission assembly 350 includes a gate connecting rod 351, a gate active crank 352, and a gate active rotating shaft 353. The gate slider 340 is slidably mounted on the gate bracket 320. The gate connecting rod 351 is connected to the gate slider 340 and the gate active crank, respectively. The gate is rotatably connected to the gate active crank 352 and the gate active rotating shaft 353. The gate active rotating shaft 353 is connected to the gate bracket 320. The gate active crank 352 is connected to the gate plate 360. The gate drive device 330 is mounted on the gate bracket 320 and drives the gate slider 340 to rise and fall in a predetermined direction. The stacking rotation drive device 370 is mounted on the stacking bracket 310. The gate bracket 320 is rotatably mounted on the stacking bracket 310. The output end of the stacking rotation drive device 370 is connected to the gate bracket 320.

[0049] The gate drive device 330 drives the gate slider 340 to rise and fall in a predetermined direction, thereby driving the gate connecting rod 351 to move. The gate connecting rod 351 then drives the gate drive crank 352 to rotate relative to the gate drive shaft 353, which in turn drives the gate plate 360 ​​to rotate. This achieves synchronous rotation of the two gate plates 360, allowing the two gates to lift or release the material bags, thus achieving the purpose of stacking. Since the stacking rotation drive device 370 is mounted on the stacking bracket 310, and the gate bracket 320 is rotatably mounted on the stacking bracket 310, with the output end of the stacking rotation drive device 370 connected to the gate bracket 320, the gate can rotate 360° under the drive of the stacking rotation drive device 370. This allows for the stacking of material bags with different patterns, such as five-patterned or six-patterned stacks, thus increasing the applicability of the stacking device 300.

[0050] In this embodiment, the two gate drive assemblies 350 are symmetrically arranged about the gate slider 340. The two gate plates 360 are symmetrically arranged about the gate slider 340.

[0051] When the gate 360 ​​is set horizontally, the gate 360 ​​can lift the material bag. When the gate 360 ​​rotates at a certain angle, the gate 360 ​​can release the material bag and make the material bag fall vertically.

[0052] In this embodiment, the gate active crank 352 includes a gate rotating rod and a gate bushing. The gate rotating rod is fixedly connected to the gate bushing, and the gate rotating rod is rotatably connected to the gate connecting rod 351. The gate bushing is rotatably connected to the gate active rotating shaft 353.

[0053] The gate drive assembly 350 also includes a gate driven crank 354 and a gate driven shaft 355. The gate driven shaft 355 is mounted on the gate bracket 320, and the gate driven crank 354 is rotatably mounted on the gate driven shaft 355. The axis of the gate driven shaft 355 is coaxial with the axis of the gate driving shaft 353. The gate driven crank 354 is connected to the gate plate 360. In other words, the crank that drives the gate plate 360 ​​to rotate is divided into two sections, one driving section and one driven section. Compared with a crank structure with only one section, this avoids the problem of crank bending caused by excessively long cranks and difficulty in ensuring coaxiality, reduces manufacturing difficulty, and saves costs.

[0054] The gate support 320 includes a gate base plate 321, a gate cover plate 322, two first gate side plates 323, two second gate side plates 324, two gate edge plates 325, and two gate support plates 326. The gate base plate 321 is connected to the two first gate side plates 323 respectively, and the two first gate side plates 323 are parallel. The first gate side plates 323 are perpendicular to the gate base plate 321. The first gate side plates 323 are connected to the gate support plates 326. The gate support plate 326 is parallel to the first gate side plate 323. The gate side plate 325 is disposed on the gate support plate 326 and parallel to the gate bottom plate 321. The gate side plate 325 is located outside the two gate support plates 326. The two second gate side plates 324 are disposed in parallel. The second gate side plates 324 are disposed perpendicular to the gate bottom plate 321 and the first gate side plate 323. The gate cover plate 322 is disposed on the two second gate side plates 324.

[0055] Preferably, the gate support 320 further includes a gate guide post 327, which is mounted on the gate support 320. The gate slider 340 is slidably connected to the gate guide post 327. This facilitates the synchronous rotation of the gate drive crank 352 and improves the reliability of the gate transmission assembly 350.

[0056] The gate drive device 330 includes a gate drive motor 331 and a gate lead screw 332. The gate drive motor 331 is mounted on the gate bracket 320 and its output end is connected to the gate lead screw 332. The gate lead screw 332 is threadedly connected to the gate slider 340. Thus, the gate drive motor 331 drives the gate lead screw 332 to rotate, thereby driving the gate slider 340 to rise and fall. The gate slider 340 then drives the gate connecting rod 351 to move, which in turn drives the gate drive crank 352 to rotate, which in turn drives the gate plate 360 ​​to rotate. In other embodiments, the gate drive device 330 may be a cylinder, or it may include a motor, a reducer, and a rack and pinion mechanism. The output end of the motor is connected to the input end of the reducer, and the output end of the reducer drives the gear to rotate. The gear drives the meshing rack to rise and fall, and the rack drives the gate slider 340 to rise and fall.

[0057] Furthermore, the palletizing device 300 also includes a palletizing frame 380 and a palletizing lifting drive device. The palletizing bracket 310 is slidably mounted on the palletizing frame 380, and the palletizing lifting drive device is mounted on the palletizing frame 380. The output end of the palletizing lifting drive device is connected to the palletizing bracket 310. This allows the gate 360 ​​of the palletizing device 300 to be raised and lowered, thus adjusting the height of the material bags and preventing them from falling from a high place and breaking, further improving the palletizing effect.

[0058] Specifically, the palletizing lifting drive device includes a palletizing lifting motor 381, a palletizing lifting reducer, a palletizing lifting gear 383, and a palletizing lifting rack 384. The output end of the palletizing lifting motor 381 is connected to the input end of the palletizing lifting reducer, and the output end of the palletizing lifting reducer is connected to the palletizing lifting gear 383. The palletizing lifting gear 383 meshes with the palletizing lifting rack 384. The palletizing lifting rack 384 is fixedly connected to the palletizing bracket 310. A palletizing guide post is fixed on the palletizing bracket 310, and a palletizing guide sleeve is provided on the palletizing frame 380. The palletizing guide post and the palletizing guide sleeve are in sliding engagement.

[0059] Furthermore, the palletizing device 300 also includes a palletizing guide rail 391, a palletizing translation roller 392, a palletizing translation rack 393, a palletizing translation gear, and a palletizing translation drive motor 395. The palletizing frame 380 is equipped with the palletizing translation roller 392, which is slidably connected to the palletizing guide rail 391. The palletizing translation drive motor 395 is mounted on the palletizing frame 380, and its output end is connected to the palletizing translation gear. The palletizing translation gear meshes with the palletizing translation rack 393, which is mounted on the palletizing guide rail 391. Thus, by driving the palletizing translation gear to rotate through the palletizing translation drive motor 395, the palletizing translation gear can be driven to translate relative to the palletizing translation rack 393. Since the palletizing translation rack 393 is fixed on the palletizing guide rail 391, the palletizing translation rack 393 does not move, and the palletizing translation gear rolls on the palletizing translation rack 393, thereby driving the palletizing frame 380 to translate relative to the palletizing guide rail 391.

[0060] Furthermore, the palletizing lifting drive device drives the palletizing bracket 310 to rise and fall in the vertical direction, and the palletizing rotation drive device 370 drives the gate bracket 320 to rotate in the horizontal plane, thereby driving the gate plate 360 ​​to rotate in the horizontal plane.

[0061] Example 2

[0062] refer to Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of the loading machine in Embodiment 2 of this utility model. Figure 9 This is a top view of the loading machine in Embodiment 2 of this utility model. The loading machine includes a movable frame, a bag conveying device 200, a palletizing device 300 as described in Embodiment 1, and a gripping system 100 for gripping bags from the bag conveying device 200 to the palletizing device 300. The bag conveying device 200, the gripping system 100, and the palletizing device 300 are mounted on the movable frame. The palletizing device 300 translates to transport the bags gripped by the gripping system 100 to a designated position for palletizing, thereby completing the palletizing process.

[0063] Specifically, the palletizing guide rail 391 of the palletizing device 300 is mounted on the movable frame.

[0064] In this embodiment, the loading machine further includes a horizontal conveying device, an inclined conveying device, a traveling device slidably mounted on the factory guide rails, and a hoisting device mounted on the traveling device for hoisting the movable frame. The horizontal conveying device is connected to the production line, and one end of the inclined conveying device is rotatably connected to the horizontal conveying device, while the other end is rotatably connected to the material bag conveying device 200. Thus, when the material bags on the production line are transported from the horizontal conveying device 200 to the inclined conveying device 200, and then from the inclined conveying device 200 to the material bag conveying device 200, they are then gripped by the gripping system 100 and placed onto the palletizing device 300, where they are then palletized.

[0065] Furthermore, the walking device slides horizontally along the walking direction, the movable frame rises and falls vertically under the action of the hoisting device, the palletizing guide rail 391 is installed on the movable frame, and the length direction of the palletizing guide rail 391 is perpendicular to the walking direction of the walking device. The palletizing lifting drive device drives the palletizing bracket 310 to rise and fall vertically, and the palletizing rotation drive device 370 drives the gate bracket 320 to rotate in the horizontal plane, thereby driving the gate plate 360 ​​to rotate in the horizontal plane. It can rise and fall in two stages along the vertical direction and can move in two mutually perpendicular directions in the horizontal plane, thus realizing five-dimensional palletizing.

[0066] refer to Figure 10 , Figure 11 and Figure 12 , Figure 10 This is a front view of the grasping system 100 in Embodiment 2 of this utility model. Figure 11 This is a top view of the grasping system 100 in Embodiment 2 of this utility model. Figure 12 This is an isometric view of the gripping system 100 in Embodiment 2 of this utility model. This embodiment provides a gripping system 100, including a connecting frame 120, a gripping device 110 mounted on the connecting frame 120, and a gripping rotation driver 140 for driving the connecting frame 120 to rotate, thereby driving the gripping device 110 to rotate. The bag conveying device 200 is located on the rotation path of the gripping device 110. Thus, the gripping device 110 can transfer bags from the bag conveying device 200 to a predetermined position, such as to the palletizing device 300, facilitating the palletizing device 300 to stack the bags. Since the bag conveying device 200 is located on the rotation path of the gripping device 110, the gripping device 110 can grip bags from the bag conveying device 200. Therefore, when the two gripping plates 115 of the gripping device 110 grip the bag, one direction of the bag can be positioned, thus improving the subsequent palletizing effect and increasing the reliability of the loading machine.

[0067] Furthermore, the bag conveying device 200 conveys the bag along a first direction. The bag conveying device 200 is equipped with a limiting member located on the conveying path of the bag. When the gripping device 110 rotates above the bag conveying device 200, the axis of the gripping drive crank 114-c is aligned along the first direction. Thus, the limiting member prevents the bag from moving further along the first direction after reaching a designated position, effectively positioning the bag in the first direction. When the gripping device 110 rotates above the bag conveying device 200, since the axis of the gripping drive crank 114-c is aligned along the first direction, the gripping plate 115 can position the bag in a second direction perpendicular to the first direction. In this way, the gripping device 110 and the limiting member work together to limit the bag in two directions, ensuring a uniform position after the bag is gripped by the gripping device 110. This improves the subsequent palletizing effect and enhances the reliability of the loading machine.

[0068] Preferably, there are two gripping devices 110, and the axes of the drive crankshafts of the two gripping devices 110 are perpendicular to each other. In this way, when there are also two palletizing devices 300 of the loading machine, the gripping devices 110 can alternately be used to transport material bags by the two palletizing devices 300. Specifically, the two gripping devices 110 are respectively the first gripping device and the second gripping device, and the two palletizing devices 300 are respectively the first palletizing device and the second palletizing device. When the first gripping device is above the bag conveying device 200, the second gripping device is above the first palletizing device. The two gripping devices are rotated 90° counterclockwise so that the first gripping device is above the second palletizing device and the second gripping device is above the bag conveying device 200. Then, the two gripping devices are rotated 90° clockwise so that the second gripping device is above the first palletizing device and the first gripping device is above the bag conveying device 200. When the gripping device is above the palletizing device, the bag can be released; when the gripping device 110 is above the bag conveying device 200, the bag can be gripped. In this way, two conveying lines for conveying bags to the palletizing device 300 can be formed, improving palletizing efficiency.

[0069] For details, please refer to Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 , Figure 13 This is an isometric view of the gripping device 110 in Embodiment 2 of this utility model. Figure 14 This is a front view of the gripping device 110 in Embodiment 2 of this utility model. Figure 15 This is a partial isometric view of the gripping device 110 in Embodiment 2 of this utility model. Figure 16This is an isometric view of the gripping plate 115 of the gripping device 110 in the second embodiment of this utility model, in the state of releasing the material bag. Figure 17 This is an isometric view of the gripping device 110 in Embodiment 2 of this utility model, showing the gripping plate 115 in the gripping bag state. The gripping device 110 includes a gripping drive assembly 111, a main board 112, a main frame 113, a gripping slider 116, two gripping transmission assemblies 114, and two gripping plates 115. The main board 112 is parallel to the XOY plane and connected to the main frame 113. The gripping transmission assembly 114 includes a gripping connecting rod 114-b, a gripping active crank 114-c, and a gripping active rotating shaft 114-d. The gripping slider 116 is connected to the main frame 114. 3. Sliding connection: The gripping link 114-b is rotatably connected to the gripping slider 116 and the gripping active crank 114-c respectively. The gripping active crank 114-c is rotatably connected to the gripping active rotating shaft 114-d. The gripping active rotating shaft 114-d is connected to the main board 112 and the axis of the gripping active rotating shaft 114-d is parallel to the X-axis. The gripping active crank 114-c is connected to the gripping plate 115. The gripping drive assembly 111 is mounted on the main frame 113 and drives the gripping slider 116 to move up and down along the Z-axis.

[0070] Since the gripping drive assembly 111 drives the gripping slider 116 to rise and fall, and the gripping slider 116 drives the gripping drive crank 114-c to rotate synchronously, the gripping drive assembly 111 can synchronously drive the gripping drive crank 114-c to rotate, thereby synchronously driving the gripping plate 115 to rotate. This avoids gripping failures caused by the gripping plate 115 failing to release or grip the material bag simultaneously, thus improving the reliability of the loading machine. Since the main board 112 is parallel to the XOY plane, and the gripping drive shaft 114-d is connected to the main board 112 with its axis parallel to the X-axis, the two gripping drive shafts 114-d can be positioned using the same main board 112. The parallelism of the two gripping drive shafts 114-d after installation is easily guaranteed, thereby improving the smoothness of the gripping transmission assembly 114's movement and thus improving the reliability of the gripping device 110.

[0071] In this embodiment, the two gripping transmission components are symmetrically arranged about the gripping slider 116. The two gripping plates 115 are symmetrically arranged about the gripping slider 116.

[0072] In this embodiment, the gripping active crank 114-c includes a gripping rotating rod and a gripping bushing. The gripping rotating rod is fixedly connected to the gripping bushing, and the gripping rotating rod is rotatably connected to the gripping connecting rod 114-b. The gripping bushing is rotatably connected to the gripping active rotating shaft 114-d.

[0073] The motherboard 112 has two first structural side surfaces 112-a parallel to the XOZ plane, and the gripping active rotating shaft 114-d has a first mounting surface. Each first mounting surface and one first structural side surface 112-a forms a group. Within each group, the first structural side surface 112-a is aligned with and in contact with the first mounting surface. Thus, ensuring the parallelism of the two first structural side surfaces 112-a, the perpendicularity of the two first structural side surfaces 112-a to the XOY plane, and the parallelism of the first mounting surface are sufficient to ensure good coaxiality of the active crankshaft mounted on the two gripping active rotating shafts 114-d, compared to directly mounting a plane parallel to the YOY plane. With two holes set in the large plate of the Z-plane, and the gripping active rotating shaft 114-d set in the two holes, and the active crankshaft installed, the coaxiality of the two gripping active rotating shafts 114-d is easier to ensure, which can effectively reduce the processing difficulty and save manufacturing costs. The parallelism of the axes of the two gripping active rotating shafts 114-d is also easier to ensure, which can improve the reliability of the gripping device 110. In addition, the way the first structural side 112-a contacts the first mounting surface can improve the structural rigidity, reduce the vibration during the movement, and the alignment of the contact surfaces provides a self-positioning function, which can simplify the assembly process, improve consistency, and the multi-faceted contact can disperse stress and extend service life.

[0074] The gripping transmission assembly 114 further includes a gripping driven crank 114-f and a gripping driven shaft 114-g. The gripping driven shaft 114-g is mounted on the main board 112, and the gripping driven crank 114-f is rotatably mounted on the gripping driven shaft 114-g. The axis of the gripping driven shaft 114-g is coaxial with the axis of the gripping driving shaft 114-d. The gripping driven crank 114-f is connected to the gripping plate 115. In other words, the crank that drives the gripping plate 115 to rotate is divided into two sections, one driving section and one driven section. Compared with a crank structure with only one section, this avoids the problem of crank bending and difficulty in ensuring coaxiality caused by excessively long cranks, reduces manufacturing difficulty, and saves costs. In addition, both the active crank 114-c and the driven crank 114-f are mounted on the same main board 112, thus ensuring coaxiality while giving the gripping plate 115 good support rigidity.

[0075] The mainboard 112 has two second structural sides parallel to the XOZ plane. The gripping driven shaft 114-g has a second mounting surface. Each second mounting surface and a second structural side forms a group. Each group of second structural sides is aligned with and in contact with the second mounting surface, and the second structural side and its corresponding first structural side 112-a are located on the same plane. Thus, ensuring that the second structural side and its corresponding first structural side 112-a are on the same plane is sufficient to achieve good coaxiality between the gripping active shaft 114-d and the gripping driven shaft 114-g, simplifying manufacturing and effectively reducing costs. Furthermore, making the mounting surfaces of the gripping active shaft 114-d and the gripping driven shaft 114-g coplanar ensures strict coaxiality between the two shafts, reducing assembly errors. Additionally, the second structural side provides extra support, enhancing rigidity, suppressing vibration, and improving motion stability. Moreover, the first structural side 112-a and the second structural side form a double mounting surface to distribute the load, reducing local stress concentration and making it suitable for gripping heavy packages.

[0076] Specifically, the first structural side 112-a has a first groove along the Y direction for mounting the gripping active shaft 114-d and the gripping active crank 114-c, and the second structural side has a second groove along the Y direction for mounting the gripping driven shaft 114-g and the gripping driven crank 114-f. Thus, the first structural side 112-a and the second structural side can be milled in one operation to create the first and second grooves, reducing machining difficulty and ensuring better coaxiality between the gripping active shaft 114-d and the gripping driven shaft 114-g.

[0077] Both ends of the gripping active rotating shaft 114-d have a first mounting surface, which is aligned with and in contact with the side surface 112-a of the first structure.

[0078] Both ends of the gripping driven shaft 114-g have second mounting surfaces, which are aligned with and in contact with the side of the second structure.

[0079] A dustproof sealing ring is provided between the gripping active crank 114-c and the gripping active shaft 114-d to prevent dust from accumulating between them and reducing their service life. Similarly, a dustproof sealing ring is provided between the gripping driven crank 114-f and the gripping driven shaft 114-g to prevent dust from accumulating between them and reducing their service life.

[0080] The main frame 113 includes a gripping support plate 113-a, a gripping base plate 113-b, a gripping first side plate 113-d, a gripping cover plate 113-e, a dustproof plate 113-f, and two gripping second side plates. The main board 112 has a first plane and a second plane parallel to the XOY plane. The gripping support plate 113-a is parallel to the YOZ plane and fixedly connected to the first plane. The gripping base plate 113-b is parallel to the XOY plane and fixedly connected to the gripping support plate 113-a. The gripping first side plate 113-d is arranged parallel to the gripping support plate 113-a. The two gripping second side plates are arranged parallel to the XOZ plane. The gripping cover plate 113-e covers the gripping first side plate 113-d and the two gripping second side plates. The dustproof plate 113-f is parallel to the YOZ plane and is installed on the second plane of the main board 112.

[0081] Preferably, the motherboard 112 and the gripping support plate 113-a are welded together.

[0082] Preferably, a reinforcing plate 113-h connects the dustproof plate 113-f to the main board 112. A reinforcing rib is provided between the gripping support plate 113-a and the main board 112.

[0083] Preferably, the main frame 113 further includes a gripping guide post 113-i, which is mounted on the main frame 113. The gripping slider 116 is slidably connected to the gripping guide post 113-i. This facilitates the synchronous rotation of the gripping active crank 114-c and improves the reliability of the gripping transmission assembly 114.

[0084] The gripping drive assembly 111 includes a gripping drive motor 111-a and a gripping lead screw 111-b. The gripping drive motor 111-a is mounted on the main frame 113 and its output end is connected to the gripping lead screw 111-b. The gripping lead screw 111-b is threadedly connected to the gripping slider 116. Thus, the gripping drive motor 111-a drives the gripping lead screw 111-b to rotate, thereby driving the gripping slider 116 to rise and fall. The gripping slider 116 then drives the gripping connecting rod 114-b to move, which in turn drives the gripping drive crank 114-c to rotate, and the gripping drive crank 114-c drives the gripping plate 115 to rotate. In other embodiments, the gripping drive assembly 111 may be a cylinder, or may include a motor, a reducer and a gear and rack mechanism, wherein the output end of the motor is connected to the input end of the reducer, the output end of the reducer drives the gear to rotate, the gear drives the rack meshing with it to rise and fall, and the rack drives the gripping slider 116 to rise and fall.

[0087] The material packages produced on the production line are transported to the loading machine;

[0088] Install pallets on the transport vehicle;

[0089] The loaders stack the pallets on the transport vehicles using a loading machine.

[0090] Use a forklift to pick up the pallet and remove the pallet and the bags on it from the transport vehicle.

[0091] Compared to traditional loading methods, this embodiment places the material bags on a pallet and uses a forklift to remove the pallet and the material bags on it from the transport vehicle. This saves the traditional process of unpacking the material bags one by one from the transport vehicle, effectively improving unloading efficiency, reducing labor costs, and minimizing material loss.

[0092] The loading machine can stack various types of pallets on the pallets, including five-petaled and six-petaled stacks.

[0093] The logistics method also includes using a forklift to pick up a pallet and transport the pallet and the package to the storage room. In this way, the pallet and the package on the pallet can be directly transported to the storage room, reducing the process of re-stacking the package and effectively improving unloading and storage efficiency.

[0094] The stacking of pallets on transport vehicles by a loading machine includes:

[0095] The material package will be conveyed from the production line via a horizontal conveyor 200;

[0096] The inclined conveyor 200 transfers the bale on the horizontal conveyor 200 to the bale conveyor 200;

[0097] The gripping system 100 transfers the material bag on the material bag conveying device 200 to the palletizing device 300;

[0098] The palletizing device 300 places the material bags onto the pallets on the conveyor vehicle.

[0099] When the palletizing device 300 places the material package onto the pallet on the conveyor vehicle, the traveling device, the hoisting device, and the palletizing device 300 need to work together to complete the palletizing.

[0100] In the above embodiments, the material package may be bagged cement or bagged grain, etc.
