Description

Technical Field

[0001] The present invention relates to the technical field of goods sorting, and in particular to a goods sorting mechanism and operation method for international freight transportation. Background Art

[0002] During the transportation of international goods, sorting and classification are required to facilitate the concentration of goods with different destinations at the same location, thus facilitating the effective transportation of international goods. When sorting goods, sorting machines are often used to facilitate the rapid and effective sorting of goods. However, in the actual use process of existing sorting machines, they usually cannot automatically clamp the goods, resulting in the need for manual placement of goods when using the sorting machine, thus wasting a large amount of manpower during the sorting of goods. Secondly, since most existing sorting machines do not have a shock-absorbing function, when transporting goods, it is easy to damage the goods due to vibration, which is not conducive to use. Therefore, a goods sorting mechanism and operation method for international freight transportation are proposed. Summary of the Invention

The international freight cargo sorting mechanism and operation method move the device to the right side of the cargo, and then move the device to the left until the cargo contacts the left side of the mounting rod. At this time, the cargo is exactly located between the two clamping plates. Immediately afterwards, the third servo motor can be started to drive the driving bevel gear to rotate, and then drive the second threaded rod to rotate through the driven bevel gear. During the rotation of the second threaded rod, it will drive the two clamping plates to move relatively until both anti-slip pads are in close contact with the outer side of the cargo, so as to clamp and fix the cargo. Then, the second servo motor can be started to drive the driving gear to rotate, and then drive the first threaded rod to rotate through the driven gear.

[0038] An operation method of a cargo sorting mechanism for international freight transportation includes the following steps:

[0039] 1) First, move the sorting device through the push rod 3 to move the device to the right side of the cargo. Then, the device can be moved to the left until the cargo contacts the left side of the mounting rod 16. At this time, the cargo is exactly located between the two clamping plates 17. Immediately afterwards, start the third servo motor 201 to drive the driving bevel gear 202 to rotate, and then drive the second threaded rod 15 to rotate through the driven bevel gear 203. During the rotation of the second threaded rod 15, the two clamping plates 17 will move relatively until both anti-slip pads 18 are in close contact with the outer side of the cargo, so as to clamp and fix the cargo.

[0040] 2) Then, start the second servo motor 131 to drive the driving gear 132 to rotate, and then drive the first threaded rod 11 to rotate through the driven gear 133. During the rotation of the first threaded rod 11, the moving block 12, the third U-shaped plate 14 and the cargo as a whole will move upward to lift the cargo until the height of the bottom of the cargo is higher than the height of the top of the storage box 5. At this time, start the first servo motor 91 to drive the worm 92 to rotate, and then drive the mounting shaft 7, the rectangular block 8 and the cargo as a whole to rotate 180 degrees to move the cargo above the storage box 5.

[0041] 3) Finally, start the second servo motor 131 to rotate in the reverse direction to drive the first threaded rod 11 to rotate in the reverse direction. At this time, during the rotation of the first threaded rod 11, the moving block 12, the third U-shaped plate 14 and the cargo as a whole will move downward until the bottom of the cargo contacts the inner bottom wall of the storage box 5. Immediately afterwards, start the third servo motor 201 to rotate in the reverse direction to drive the second threaded rod 15 to rotate in the reverse direction. At this time, during the rotation of the second threaded rod 15, the two clamping plates 17 will move away from each other to release the fixation of the cargo, so as to place the cargo inside the storage box 5, thus automatically completing the clamping and placing operations of the cargo. At this time, move the sorting device through the push rod 3 to transport the cargo.

[0042] During use, move the device to the right side of the goods, and then move the device to the left until the goods contact the left side of the mounting rod 16. At this time, the goods are exactly located between the two clamping plates 17. Immediately afterwards, the third servo motor 201 can be started through the controller 22 to drive the driving bevel gear 202 to rotate, and then drive the second threaded rod 15 to rotate through the driven bevel gear 203. During the rotation of the second threaded rod 15, the two clamping plates 17 will move relatively until both anti-slip pads 18 are in close contact with the outer side of the goods, so as to clamp and fix the goods. Then, the second servo motor 131 can be started to drive the driving gear 132 to rotate, and then drive the first threaded rod 11 to rotate through the driven gear 133. During the rotation of the first threaded rod 11, the moving block 12, the third U-shaped plate 14 and the goods as a whole will move upward to lift the goods until the height of the bottom of the goods is higher than the height of the top of the storage box 5. At this time, the first servo motor 91 can be started to drive the worm 92 to rotate, and then drive the mounting shaft 7, the rectangular block 8 and the goods as a whole to rotate 180 degrees to move the goods above the storage box 5. Immediately afterwards, the second servo motor 131 can be started to rotate in the reverse direction to drive the first threaded rod 11 to rotate in the reverse direction. At this time, during the rotation of the first threaded rod 11, the moving block 12, the third U-shaped plate 14 and the goods as a whole will move downward until the bottom of the goods contacts the inner bottom wall of the storage box 5. Finally, the third servo motor 201 can be started to rotate in the reverse direction to drive the second threaded rod 15 to rotate in the reverse direction. At this time, during the rotation of the second threaded rod 15, the two clamping plates 17 will move away from each other to release the fixation of the goods, so as to place the goods inside the storage box 5, thus automatically completing the clamping and placing operations of the goods without manually placing the goods, which facilitates the use. At this time, the sorting device can be moved through the push rod 3 to perform the transportation operation of the goods. When the goods in the storage box 5 are vibrated during transportation, the goods and the storage box 5 will move downward as a whole to squeeze the two first buffer springs 27, and will also drive the two sliders 292 to move relatively through the two connecting rods 294 to squeeze the second buffer spring 293, so as to degrade a part of the impact force of the vibration through the elastic force of the buffer spring. Secondly, when the storage box 5 moves downward, it will also squeeze the piston rods of the two hydraulic dampers 26 to degrade another part of the impact force of the vibration, and finally achieve the shock absorption effect, so as to protect the transported goods from shock as much as possible to avoid damage to the goods.

[0043] In summary, for the international freight cargo sorting mechanism and operation method, the device is moved to the right side of the cargo, and then moved to the left until the cargo contacts the left side of the mounting rod 16. At this time, the cargo is exactly located between the two clamping plates 17. Then, the third servo motor 201 can be started to drive the driving bevel gear 202 to rotate, and then drive the second threaded rod 15 to rotate through the driven bevel gear 203. During the rotation of the second threaded rod 15, it will drive the two clamping plates 17 to move relatively until both anti-slip pads 18 are in close contact with the outer side of the cargo, so as to clamp and fix the cargo. Then, the second servo motor 131 can be started to drive the driving gear 132 to rotate, and then drive the first threaded rod 11 to rotate through the driven gear 133. During the rotation of the first threaded rod 11, it will drive the moving block 12, the third U-shaped plate 14 and the cargo as a whole to move upward, so as to lift the cargo until the height of the bottom of the cargo is higher than the height of the top of the storage box 5. At this time, the first servo motor 91 can be started to drive the worm 92 to rotate, and then drive the mounting shaft 7, the rectangular block 8 and the cargo as a whole to rotate 180 degrees, so as to move the cargo above the storage box 5. Then, the second servo motor 131 can be started to rotate in the reverse direction, so as to drive the first threaded rod 11 to rotate in the reverse direction. At this time, during the rotation of the first threaded rod 11, it will drive the moving block 12, the third U-shaped plate 14 and the cargo as a whole to move downward until the bottom of the cargo contacts the inner bottom wall of the storage box 5. Finally, the third servo motor 201 can be started to rotate in the reverse direction, so as to drive the second threaded rod 15 to rotate in the reverse direction. At this time, during the rotation of the second threaded rod 15, it will drive the two clamping plates 17 to move away from each other, thus releasing the fixation of the cargo, so as to place the cargo inside the storage box 5, thereby automatically completing the clamping and placing operations of the cargo, without the need to place the cargo manually, which is convenient for use. Secondly, by setting the limiting groove 24 and the limiting block 25, when the cargo in the storage box 5 is vibrated during transportation, the cargo and the storage box 5 will move downward as a whole, so as to squeeze the two first buffer springs 27, and will also drive the two sliders 292 to move relatively through the two connecting rods 294, so as to squeeze the second buffer spring 293, thereby degrading a part of the impact force of the vibration through the elastic force of the buffer spring. Secondly, when the storage box 5 moves downward, it will also squeeze the piston rods of the two hydraulic dampers 26, so as to degrade another part of the impact force of the vibration, and finally achieve the shock absorption effect. By protecting the transported cargo from shock, it is possible to avoid damage to the cargo as much as possible, solving the problem that in the actual use process of the existing sorting machines, they usually cannot automatically clamp the cargo, resulting in the need to place the cargo manually when using the sorting machines, thus wasting a lot of manpower when sorting the cargo. Secondly, since most of the existing sorting machines do not have the function of shock absorption, it causes problems during the transportation of the cargo.The problem is that the goods are easily damaged due to vibration, which is not conducive to use.
