DETAILED DESCRIPTION

[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 Figure 1-Figure 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 stacking the bagged goods, the personnel first lay the soft pallet 6 flat on the lower side of the baffle frame 8, and then control the motor 13 to operate, so that the threaded rod 11 rotates and drives the baffle frame 8 to move down to the lowest point, and then the lifting column, telescopic bracket and mechanical gripper 3 cooperate to grab the bagged goods transported on the conveyor belt. After grabbing, the mechanical gripper 3 drives the goods to rotate to the upper side of the baffle frame 8, and finally the mechanical gripper 3 stacks the bagged goods on the upper side of the soft pallet 6 in sequence. During the stacking process, the baffle frame 8 blocks the edge of the stacked goods, and when the height of the stacked goods changes, the height of the baffle frame 8 can also be increased accordingly, which can effectively prevent the goods from tipping over during the stacking process;

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

[0036] Example 2: Please refer to Figure 4-Figure 7 The present embodiment further explains the first embodiment. The suspension assembly includes an oblique hanging rod 14 installed on the outside of the corner column 9, and the oblique hanging rod 14 is rotatably connected to the corner column 9 through a connecting shaft. A bent connecting rod 15 is fixedly embedded on the outside of the oblique hanging rod 14. 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 oblique hanging rod 14. An arc spring 17 is fixedly installed on the outside of the oblique hanging rod 14, and the arc spring 17 is located on the inner side of the corner column 9. One end of the arc spring 17 away from the oblique hanging rod 14 is fixedly connected to the corner column 9.

[0037] The locking assembly includes a pin rod 18 that can move inside the corner column 9, a washer 19 is fixedly sleeved on the outer side of the pin rod 18, a spring 20 is movably sleeved on the outer side of the pin rod 18, and the two ends of the spring 20 are movably abutted against the corner column 9 and the washer 19 respectively, and both ends of the pin rod 18 are provided with hemispherical parts, and a hemispherical groove 21 is opened on the outer side of the diagonal hanging rod 14 corresponding to the pin rod 18, and the pin rod 18 is movably clamped with the diagonal hanging rod 14 through the hemispherical groove 21, and the hemispherical part of the pin rod 18 is embedded in the hemispherical groove 21 for locking the diagonal hanging rod 14.

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

[0039] In this embodiment: after the baffle 8 moves down to the lowest position, the personnel insert the four slings 7 between the four diagonal hanging rods 14 and the four rubber sleeves 16 respectively. Due to its own elasticity, the rubber sleeves 16 can cooperate with the diagonal hanging rods 14 to squeeze and clamp the slings 7, thereby preventing the slings 7 from detaching from the diagonal hanging rods 14;

[0040] When the diagonal hanging rod 14 moves upward with the baffle frame 8, the sling 7 can be driven upward. Since the hemispherical portion at one end of the pin rod 18 is embedded in the hemispherical groove 21, and the other end is movably opposed to the arc baffle plate 22, the pin rod 18 cannot move out of the hemispherical groove 21 inside the corner column 9, that is, the pin rod 18 can lock the diagonal hanging rod 14 through the hemispherical groove 21 at this time, and the diagonal hanging rod 14 cannot rotate at this time. When the stacking reaches a certain height, the baffle frame 8 drives the sling 7 to continue to move upward for a distance, so that the bent baffle rod 35 is against the protrusion 25, which makes it convenient for personnel to drive a forklift to quickly insert the fork rod into the sling 7.

[0041] Example 3: Please refer to Figure 3 , Figure 7 This embodiment further explains Example 2. There are two groups of bending baffles 35 on the support frame 12, and they are symmetrically distributed. The bending baffles 35 are close to the upper end of the support frame 12. The connection between the bending baffles 35 and the protrusions 25 is a movable abutment. The bending baffles 35 can drive the arc baffle 22 to move downward through the protrusions 25.

[0042] In this embodiment: when the bent blocking rod 35 abuts against the protrusion 25, the threaded rod 11 continues to drive the blocking frame 8 to move upward, and the bent blocking rod 35 drives the arc baffle 22 to move downward on the outer side of the corner column 9 through the protrusion 25, so that the arc baffle 22 is away from the pin 18. At this time, when the oblique hanging rod 14 continues to move upward with the blocking frame 8, the oblique hanging rod 14 will rotate under the pulling force of the sling 7 until the sling 7 is separated from the oblique hanging rod 14, which is conducive to the sling 7 directly separating from the oblique hanging rod 14, so that the forklift can quickly transfer the stacked goods;

[0043] When the sling 7 is detached from the diagonal hanging rod 14, the diagonal hanging rod 14 will rotate and reset under the drive of the compression elastic force of the arc spring 17, so that the end of the pin rod 18 is re-embedded in the hemispherical groove 21 outside the diagonal hanging rod 14, and then the threaded rod 11 rotates to drive the baffle frame 8 to move downward, and the arc baffle plate 22 will move upward and reset under the drive of the compression elastic force of the spring 24, blocking the pin rod 18, so that the pin rod 18 locks the diagonal hanging rod 14 through the hemispherical groove 21.

[0044] Example 4: Please refer to Figure 2 , Figure 8 This embodiment further explains the first embodiment. A driving assembly is installed between the lifting column 2 and the support plate 4. The driving assembly includes a gear 1 26 fixedly installed on the lower end of the support shaft of the lifting column 2. The upper end of the base 1 is located on the outer side of the lifting column 2 and is fixedly installed with a motor 27. The outer side of the driving shaft of the motor 27 is fixedly sleeved with a gear 28. The motor 27 can drive the lifting column 2 to rotate through the gear 1 26 and the gear 2 28, and the connection between the gear 2 28 and the gear 1 26 is a meshing connection.

[0045] The outer side of gear one 26 is also equipped with gear three 29, and gear three 29 is rotatably installed on the lower side of the support plate 4. A disc 30 is fixedly installed on the upper end of gear three 29, and a plurality of arc-shaped baffles 31 equidistantly distributed in a circle are fixedly installed on the upper end of the disc 30. A roller 32 is rotatably installed on the lower end of the support plate 4 through the mounting shaft, and the arc-shaped baffle 31 can drive the support plate 4 to move through the roller 32.

[0046] The connection between the roller 32 and the arc-shaped baffle 31 is in rolling contact. A plurality of springs three 33 distributed at equal distances are fixedly installed on one end of the support plate 4 away from the lifting column 2, and the end of the spring three 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 springs three 33. The cover plate 34 is used to cover the plurality of springs three 33, and the connection between the cover plate 34 and the support plate 4 is a fixed connection.

[0047] In this embodiment: in the process of motor 2 27 driving the lifting column 2 and the mechanical gripper 3 to rotate for picking up and stacking through gear 1 26 and gear 2 28, gear 1 26 drives the disc 30 to rotate through gear 3 29. As the arc-shaped baffle 31 rotates with the disc 30, the roller 32 rolls along the arc-shaped edge of the arc-shaped baffle 31. In this process, the arc-shaped baffle 31 and the roller 32 drive the support plate 4 to move. When the roller 32 disengages from the arc-shaped baffle 31, the support plate 4 moves back and resets under the drive of the compression force of spring 3 33. This reciprocating motion is conducive to making the surface of the bagged goods shake smooth and evenly distributed in the packaging bag, thereby further improving the stability of the stacked goods.
