[0002] A cargo ship is mainly used for carrying goods, and most of its cabins are used for storing goods. In order to improve the space utilization rate of the cargo hold of the cargo ship, before the goods are put into the cargo hold, a palletizer is used to palletize the goods.

[0003] The existing Chinese patent CN217920381U discloses an automatic palletizer with a film-wrapping function. By building a gantry above the operating platform, the clamping plates on both sides of the gantry are used to clamp the goods and then longitudinally wrap the film, and the operating platform rotates to horizontally wrap the film, realizing the all-round wrapping of the goods by the film, improving the film-wrapping efficiency of the goods, comprehensively wrapping the film to avoid damage to the goods, and ensuring the stability of the stack. However, in the process of using the above device, the goods are first palletized. After the palletizing of the goods is completed, the palletized goods are transported to the operating platform through the feeding conveyor belt, and finally the operating platform rotates to perform film-wrapping treatment on the palletized goods. When the goods, especially bagged goods, are unevenly distributed or stacked too high during the palletizing and transportation process, the goods may tip over.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figures 1-4 The illustrated device is a cargo stacking anti-dumping device for a ship cargo hold, comprising a base 1, a lifting column 2 is mounted on the upper end of the base 1, and the lifting column 2 is rotatably connected to the base 1 through a supporting shaft, a mechanical gripper 3 is mounted on the lifting column 2 through a telescopic bracket, a pallet 4 that can move left and right is also movably mounted on the upper end of the base 1, a plurality of rollers 5 are fixedly mounted on the lower end of the pallet 4, a soft pallet 6 is laid on the upper end of the pallet 4, and slings 7 are fixedly mounted at the four corners of the soft pallet 6, and an anti-dumping mechanism is also included to prevent the cargo from tipping over during stacking, and the anti-dumping mechanism is mounted on the upper end of the pallet 4; a hanging assembly is used to hang the soft pallet 6, and the hanging assembly is mounted on the anti-dumping mechanism; a locking assembly is used to lock the hanging assembly, and the locking assembly is mounted on the outside of the hanging assembly; a bending stopper 35 is used to release the locking of the hanging assembly by the locking assembly, and the bending stopper 35 is fixedly mounted on the anti-dumping mechanism.

[0032] The anti-fall mechanism includes a baffle frame 8 installed on the upper side of the soft pallet 6. The baffle frame 8 is used to prevent the goods from falling over during the stacking process. Corner columns 9 are fixedly embedded at the four corners of the baffle frame 8. Two symmetrically distributed connecting blocks 10 are fixedly installed on the outer side of the baffle frame 8. Threaded rods 11 are installed inside the two connecting blocks 10. A support frame 12 is fixedly installed on the outer side of the threaded rod 11 corresponding to the upper end of the support plate 4.

[0033] The connection between the bent baffle rod 35 and the support frame 12 is a fixed connection. The threaded rod 11 is rotatably connected to the support plate 4 and the support frame 12 respectively through bearings. The threaded rod 11 is used to drive the baffle frame 8 to rise and fall. The two threaded rods 11 are assembled through a synchronous wheel and a synchronous belt transmission. The upper end of one threaded rod 11 is fixedly connected to a motor 13, and the motor 13 is fixedly installed on the upper end of the corresponding support frame 12.

[0034] Working principle: Before palletizing bagged goods, the operator first lays the soft pallet 6 flat under the retaining frame 8, and then controls the operation of the first motor 13 to rotate the threaded rod 11 to drive the retaining frame 8 to move down to the lowest position. Then, the lifting column, telescopic bracket and mechanical gripper 3 cooperate to grasp the bagged goods conveyed on the conveyor belt. After grasping, the mechanical gripper 3 drives the goods to rotate to the upper side of the retaining frame 8. Finally, the mechanical gripper 3 stacks the bagged goods on the upper side of the soft pallet 6 in sequence. During the palletizing process, the retaining frame 8 blocks the edges of the palletized goods, and when the height of the palletized goods changes, the height of the retaining frame 8 can also increase accordingly, which can effectively prevent the goods from tipping over during the palletizing process;

[0035] When the goods are palletized, the operator drives the forklift to insert the two fork rods of the forklift into the two slings 7 respectively, and then transports the palletized goods through the four slings 7 and the soft pallet 6. During the transportation process, the four slings 7 protect the four corners of the palletized goods, which can effectively prevent the goods from tipping over during the hoisting and transportation process, that is, effectively avoid the tipping phenomenon before the palletized goods are wrapped with film for protection.

[0036] Embodiment 2: Please refer to Figures 4-7 , this embodiment further illustrates Embodiment 1. The suspension assembly includes an inclined hanging rod 14 installed outside the corner post 9, and the inclined hanging rod 14 is rotatably connected to the corner post 9 through a connecting shaft. A bent connecting rod 15 is fixedly embedded on the outside of the inclined hanging rod 14, and a rubber sleeve 16 is movably sleeved on the outside of the bent connecting rod 15. The rubber sleeve 16 can prevent the sling 7 from detaching from the inclined hanging rod 14. An arc-shaped spring 17 is fixedly installed on the outside of the inclined hanging rod 14, and the arc-shaped spring 17 is located inside the corner post 9. One end of the arc-shaped spring 17 away from the inclined hanging rod 14 is fixedly connected to the corner post 9.

[0037] The locking assembly includes a pin rod 18 that can move inside the corner post 9. A washer 19 is fixedly sleeved on the outside of the pin rod 18. A first spring 20 is movably sleeved on the outside of the pin rod 18, and both ends of the first spring 20 are movably abutted against the corner post 9 and the washer 19 respectively. Hemispherical parts are provided at both ends of the pin rod 18. A hemispherical card slot 21 is opened on the outside of the inclined hanging rod 14 corresponding to the pin rod 18, and the pin rod 18 is movably clamped with the inclined hanging rod 14 through the hemispherical card slot 21. The hemispherical part of the pin rod 18 is embedded in the hemispherical card slot 21 to lock the inclined hanging rod 14.

[0038] An arc-shaped baffle 22 is movably sleeved on the outer side of the corner post 9, and the connection between the pin rod 18 and the arc-shaped baffle 22 is a movable abutment. Two symmetrically distributed embedded blocks 23 are fixedly installed on the side of the arc-shaped baffle 22 close to the corner post 9. The embedded blocks 23 are slidably connected to the corner post 9 through limit straight grooves. The embedded blocks 23 are used to prevent the arc-shaped baffle 22 from detaching from the corner post 9. A second spring 24 is fixedly installed at the center of the lower end of the embedded block 23, and the end of the second spring 24 away from the embedded block 23 is fixedly connected to the corner post 9. A convex block 25 is fixedly installed on the outer side of the arc-shaped baffle 22.

[0039] In this embodiment: After the retaining frame 8 is moved down to the lowest position, the operator inserts the four suspension straps 7 between the four inclined hanging rods 14 and the four rubber sleeves 16 respectively. Due to its own elastic properties, the rubber sleeve 16 can cooperate with the inclined hanging rod 14 to squeeze and clamp the suspension strap 7, thereby preventing the suspension strap 7 from detaching from the inclined hanging rod 14.

[0040] During the upward movement of the inclined hanging rod 14 with the retaining frame 8, the suspension strap 7 can be driven to move upward. Since the hemispherical portion at one end of the pin rod 18 is embedded in the hemispherical card slot 21, and the other end is movably abutted against the arc-shaped baffle 22, the pin rod 18 cannot move inside the corner post 9 and detach from the hemispherical card slot 21. That is, at this time, the pin rod 18 can lock the inclined hanging rod 14 through the hemispherical card slot 21, and the inclined hanging rod 14 cannot rotate at this time. When the stacking reaches a certain height, the retaining frame 8 drives the suspension strap 7 to continue to move upward for a certain distance. After the bent retaining rod 35 abuts against the convex block 25, it is convenient for the operator to drive the forklift to quickly insert the fork rod into the suspension strap 7.

[0041] Embodiment Three: Please refer to Figure 3 、 Figure 7 This embodiment further describes Embodiment Two. The number of bent retaining rods 35 on the support frame 12 is two groups and is symmetrically distributed. The bent retaining rods 35 are close to the upper end of the support frame 12. The connection between the bent retaining rods 35 and the convex block 25 is a movable abutment. The bent retaining rods 35 can drive the arc-shaped baffle 22 to move downward through the convex block 25.

[0042] In this embodiment: When the bent retaining rod 35 abuts against the convex block 25 and the threaded rod 11 continues to drive the retaining frame 8 to move upward, the bent retaining rod 35 will drive the arc-shaped baffle 22 to move downward on the outer side of the corner post 9 through the convex block 25, so that the arc-shaped baffle 22 moves away from the pin rod 18. At this time, during the upward movement of the inclined hanging rod 14 with the retaining frame 8, the inclined hanging rod 14 will rotate under the pulling force of the suspension strap 7 until the suspension strap 7 detaches from the inclined hanging rod 14, which is beneficial to directly detach the suspension strap 7 from the inclined hanging rod 14 and facilitate the forklift to quickly transfer the stacked goods.

[0043] When the sling 7 disengages from the diagonal hanging rod 14, the diagonal hanging rod 14 will rotate and reset under the driving force of the compressed elastic force of the arc spring 17, so that the end of the pin rod 18 is re-embedded into the hemispherical card slot 21 outside the diagonal hanging rod 14. Then, the threaded rod 11 rotates to drive the retaining frame 8 to move downward, and the arc-shaped baffle 22 will move upward and reset under the driving force of the compressed elastic force of the second spring 24 to block the pin rod 18, so that the pin rod 18 locks the diagonal hanging rod 14 through the hemispherical card slot 21.

[0044] Embodiment 4: Please refer to Figure 2 , Figure 8 , in this embodiment, a driving component is installed between the lifting column 2 and the support plate 4. The driving component includes a first gear 26 fixedly installed at the lower end of the support shaft of the lifting column 2. A second motor 27 is fixedly installed outside the upper end of the base 1 on the outside of the lifting column 2. A second gear 28 is fixedly sleeved on the outside of the driving shaft of the second motor 27. The second motor 27 can drive the lifting column 2 to rotate through the first gear 26 and the second gear 28, and the connection method between the second gear 28 and the first gear 26 is meshing connection.

[0045] A third gear 29 is also installed in cooperation with the outside of the first gear 26, and the third gear 29 is rotatably installed under the support plate 4. A disc 30 is fixedly installed at the upper end of the third gear 29. A plurality of arc-shaped blocking strips 31 evenly distributed at equal circumferences are fixedly installed at the upper end of the disc 30. A roller 32 is rotatably installed at the lower end of the support plate 4 through a mounting shaft. The arc-shaped blocking strips 31 can drive the support plate 4 to move through the roller 32.

[0046] The connection method between the roller 32 and the arc-shaped blocking strips 31 is rolling contact. A plurality of third springs 33 evenly distributed at equal distances are fixedly installed at one end of the support plate 4 away from the lifting column 2, and one end of the third springs 33 away from the support plate 4 is fixedly connected to the base 1. A cover plate 34 is installed on the upper side of the plurality of third springs 33. The cover plate 34 is used to cover the plurality of third springs 33, and the connection method between the cover plate 34 and the support plate 4 is fixed connection.

[0047] In this embodiment: During the process of the second motor 27 driving the lifting column 2 and the mechanical gripper 3 to rotate to pick up and stack goods through the first gear 26 and the second gear 28, the first gear 26 drives the disc 30 to rotate through the third gear 29. During the process of the arc-shaped blocking strips 31 rotating with the disc 30, the roller 32 will roll along the arc-shaped edge of the arc-shaped blocking strips 31. During this process, the arc-shaped blocking strips 31 will drive the support plate 4 to move through the roller 32. When the roller 32 disengages from the arc-shaped blocking strips 31, the support plate 4 will move back and reset under the driving force of the compressed elastic force of the third springs 33. Repeating this process is beneficial to making the surface of the bagged goods on the surface shake and flatten, and making the goods evenly distributed in the packaging bag, thereby further improving the stability of the stacked goods.
