Description

Technical Field

[0001] This utility model relates to the field of material packaging vehicle technology, and in particular to a loading and palletizing host 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 bag conveyor mounted on the guide rails, a traveling device mounted on the guide rails and connected to the output end of the horizontal bag conveyor, and an inclined bag conveyor. One end of the inclined bag conveyor is connected to the output end of the horizontal bag 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 output end of the inclined bag conveyor is moved to the loading position via a traveling device. Then, the horizontal and inclined bag conveyors are activated to transport the bagged cement to the output end of the inclined bag conveyor. Next, workers transfer the bagged cement from the inclined bag conveyor to the vehicle, completing a multi-layer stack. After completing one stack, the traveling device moves the output end of the inclined bag conveyor to the next stacking position, and the stacking continues in a cycle. During the stacking process, when the height of the inclined bag 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] Chinese patent (CN104192586A) discloses a loading and palletizing main unit for a bagged cement loading machine, including a distributing device, an unloading device, a palletizing device, and a support. The distributing device, unloading device, and palletizing device are sequentially mounted on the support. The input end of the distributing device is connected to the output end of the previous station. The distributing device has at least two output ends. Each output end of the distributing device is horizontally connected to the input end of one of the unloading devices, and each output end of the unloading device is vertically connected to the input end of one of the palletizing devices. The output end of each palletizing device vertically conveys the bagged cement to a designated position, and all the bagged cement conveyed to the designated position by the palletizing devices are arranged in a horizontal straight line. However, this loading and palletizing main unit has a complex structure, is heavy, and has poor reliability.

[0005] Therefore, it is necessary to develop a new loading and palletizing host to simplify its structure, reduce its weight, and improve its reliability. Utility Model Content

[0014] Optionally, the palletizing device includes a palletizing bracket, a palletizing rotation drive device, a gate bracket, a gate drive device, a gate slider, two gate transmission assemblies, and two gate plates. The gate transmission assembly includes a gate connecting rod, a gate drive crank, and a gate drive shaft. The gate slider is slidably mounted on the gate bracket.

The output end of the hoisting device is connected to the movable frame of the loading and palletizing host.

[0017] The loading and palletizing host and loading machine provided by this utility model have the following beneficial effects:

[0018] Since the bag conveying device and the palletizing device are located on the rotation path of the gripping device, the gripping system can transfer the bags from the bag conveying device to the palletizing device, and then the palletizing device can stack the bags onto the conveyor. Because only one bag conveying device, gripping system, and palletizing device are needed for palletizing, the entire loading and palletizing machine has a simple structure and is lightweight. Due to its simple structure, the failure rate of the loading and palletizing machine is also low, resulting in high reliability. Furthermore, the gripping device can transfer the bags from the bag conveying device to the palletizing device, facilitating the stacking of the bags. Since the bag conveying device is located on the rotation path of the gripping device, the gripping device can grip the bags from the bag conveying device. Therefore, when the two gripping plates of the gripping device grip the bags, one direction of the bag can be positioned, which improves the subsequent palletizing effect and increases the reliability of the loading machine.

[0051] Example 1

[0052] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 1 This is a structural schematic diagram from one perspective of the loading and palletizing host in Embodiment 1 of this utility model. Figure 2 This is a structural schematic diagram from another perspective of the loading and palletizing host in Embodiment 1 of this utility model. Figure 3 This is a front view of the grasping system 100 in Embodiment 1 of this utility model. Figure 4 This is a top view of the grasping system 100 in Embodiment 1 of this utility model. Figure 5This is an isometric view of the gripping system 100 in Embodiment 1 of this utility model. This embodiment provides a loading and palletizing host, including a movable frame 700, a gripping system 100, a palletizing device 300 for vertically lowering packages, a package conveying device 200 for conveying packages along a first direction, and a package transfer device 400 for conveying packages along the first direction to the palletizing device 300. The package conveying device 200, the palletizing device 300, and the package transfer device 400 are mounted on the movable frame 700. The gripping system 100 includes 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 the gripping device 110 in a horizontal plane. The material bag conveying device 200 and the material bag transfer device 400 are located on the rotation path of the gripping device 110. The connecting frame 120 is rotatably connected to the movable frame 700, and the gripping rotation driver 140 is mounted on the movable frame 700.

[0053] Since the bag conveying device 200 and the bag transfer device 400 are located on the rotation path of the gripping device 110, the bag on the bag conveying device 200 can be transferred to the bag transfer device 400 by the gripping system 100, and then transported to the palletizing device 300 by the bag transfer device 400. Finally, the bag is stacked on the conveyor vehicle by the palletizing device 300. Since only one bag conveying device 200, gripping system 100, bag transfer device 400 and palletizing device 300 are needed to achieve palletizing, the structure of the entire loading and palletizing host is relatively simple and lightweight. Moreover, due to the simple structure, the failure rate of the loading and palletizing host is also low, thus ensuring good reliability. Furthermore, the bag on the bag conveying device 200 can be transferred to the bag transfer device 400 via the gripping device 110, and then transferred to the palletizing device 300 via the bag transfer device 400, thereby 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 the bag from the bag conveying device 200. Therefore, when the two gripping plates 115 of the gripping device 110 grip the bag, the bag can be positioned in one direction, which can improve the subsequent palletizing effect and increase the reliability of the loading machine.

[0054] 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, it grips or releases the bag along a second direction perpendicular to 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, it grips or releases the bag along the second direction perpendicular to the first direction, thereby positioning the bag in the second 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 gripping by the gripping device 110, thereby improving the subsequent palletizing effect and increasing the reliability of the loading machine.

[0055] Preferably, there are two gripping devices 110, which are perpendicular to each other. In this way, when there are also two palletizing devices 300 on 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 the first gripping device and the second gripping device, respectively, and the two palletizing devices are the first palletizing device and the second palletizing device, respectively. 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. Furthermore, when the gripping device 110 is above the palletizing device 300, it can release the bag; when the gripping device 110 is above the bag conveying device 200, it can grip the bag. In this way, two conveying lines for conveying bags to the palletizing device 300 can be formed, improving palletizing efficiency.

[0056] refer to Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 , Figure 6 This is an isometric view of the gripping device 110 in Embodiment 1 of this utility model. Figure 7 This is a front view of the gripping device 110 in Embodiment 1 of this utility model. Figure 8 This is a partial isometric view of the gripping device 110 in Embodiment 1 of this utility model. Figure 9This is an isometric view of the gripping plate 115 of the gripping device 110 in the material release state in Embodiment 1 of this utility model. Figure 10 This is an isometric view of the gripping device 110 in Embodiment 1 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] Preferably, the motherboard 112 and the gripping support plate 113-a are welded together.

[0069] 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.

[0070] 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.

[0071] 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.

Figure 13 This is a schematic diagram of the stacking gate of the stacking device 300 in Embodiment 1 of this utility model. Figure 14 This is a structural schematic diagram of the palletizing device 300 from one perspective in Embodiment 1 of this utility model. Figure 15 This is a structural schematic diagram of the palletizing device 300 from another perspective in Embodiment 1 of this utility model. Figure 16 This is a top view of the palletizing device 300 in Embodiment 1 of this utility model. Figure 17 This is a front view schematic diagram of the palletizing device 300 in Embodiment 1 of this utility model. The palletizing device includes 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 drive crank 352, and a gate drive shaft 353. The gate slider 340 is slidably mounted on the gate bracket 320. The gate connecting rod 351 rotates with the gate slider 340 and the gate drive crank 352 respectively. The gate's active crank 352 is rotatably connected to the gate's active rotating shaft 353, which is connected to the gate bracket 320. The gate's 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 move up and down in a predetermined direction. 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. The output end of the stacking rotation drive device 370 is connected to the gate bracket 320.

[0073] 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 palletizing. Since the palletizing rotation drive device 370 is mounted on the palletizing bracket 310, and the gate bracket 320 is rotatably mounted on the palletizing bracket 310, with the output end of the palletizing rotation drive device 370 connected to the gate bracket 320, the gate can rotate 360° under the drive of the palletizing 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 palletizing device 300.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] The material bag conveying device 200 includes a belt conveyor.

One end of the inclined conveying device is rotatably connected to the horizontal conveying device, and the other end is rotatably connected to the material bag conveying device 200. The movable frame 700 of the loading and palletizing host is slidably mounted vertically on the traveling device 500. The output end of the hoisting device 600 is connected to the movable frame 700 of the loading and palletizing host. Thus, the movable frame 700 can be driven to rise and fall by the hoisting device 600, and the movable frame 700 can be driven to move by the traveling device 500.

[0087] Furthermore, the walking device 500 slides horizontally along the walking direction, the movable frame 700 is vertically raised and lowered under the action of the hoisting device 600, and the palletizing guide rail 391 is installed on the movable frame 700, with the length direction of the palletizing guide rail 391 perpendicular to the walking direction of the walking device 500. 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 vertically and move in two mutually perpendicular directions in the horizontal plane, thus achieving five-dimensional palletizing.

[0088] In this embodiment, the walking device 500 is provided with a walking guide sleeve, and the movable frame 700 is provided with a walking guide column. The walking guide sleeve and the walking guide column slide together, which can improve the stability of the loading and palletizing host lifting and lowering.

The bag conveying device 200, the gripping system 100, and the palletizing device 300 are mounted on the movable frame 700. The bags gripped by the gripping system 100 are conveyed to a designated position for palletizing by the translation of the palletizing device 300, thereby completing the palletizing process.

[0091] Specifically, the palletizing guide rail 391 of the palletizing device 300 is mounted on the movable frame 700.

[0092] In this embodiment, the loading machine further includes a horizontal conveying device, an inclined conveying device, a traveling device 500 slidably mounted on the factory guide rails, and a hoisting device 600 mounted on the traveling device 500 for hoisting the movable frame 700. 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.
