[0002] With the rapid development of e-commerce and global supply chains, the logistics industry is increasingly demanding higher efficiency, safety, and cost control in cargo handling. Traditional logistics loading and unloading mainly relies on manual operation of forklifts, hydraulic platforms, or simple conveyor equipment. In some loading and unloading scenarios, such as cryogenic pipes in liquefied natural gas projects, the weld seams are easily damaged when unloading, and they must be flipped so that the weld seams are facing upwards for inspection and subsequent welding. Existing overhead cranes and forklifts do not have the function of flipping goods, resulting in a high rate of workplace injuries due to manual flipping.

[0003] For these precision equipment and irregularly shaped components, it is necessary to move from rough stacking to precise flow, improve process integration rate, reduce multiple transfers, and improve logistics efficiency. Therefore, there is an urgent need for an automated loading and unloading device for logistics transportation that is highly automated and easy to position and flip goods. Summary of the Invention

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-13 Specifically, the following embodiments are included:

[0038] Example 1:

[0039] An automated loading and unloading device for logistics transportation includes a mobile trolley 10 and a positioning and clamping unit 1. The positioning and clamping unit 1 includes an upper clamp 11, a lower clamp 12, and a drive mechanism 13. The mobile trolley 10 adopts a multi-axis movement mode, specifically including a gantry frame, an X-axis moving part, a Y-axis moving part, and a Z-axis moving part. The X-axis moving part, the Y-axis moving part, and the Z-axis moving part are slidably connected on the gantry frame. The X-axis moving part and the Y-axis moving part are both composed of a crossbeam mounting base or a plate welded mounting base, a guide rail slider assembly, a gear transmission assembly, a servo motor, and other parts. The movement in the X / Y axis direction is achieved by controlling the gear transmission through the servo motor. The Z-axis moving part is a robotic arm in the Z-axis direction, used for loading and unloading goods, grabbing goods and moving them between the upper clamp 11 and the lower clamp 12 of the positioning and clamping unit 1.

[0040] The driving mechanism 13 includes a support frame 101, on which a conveyor 2 is mounted. The conveyor 2 drives the upper clamp 11 and the lower clamp 12 to clamp the goods. The upper clamp 11 and the lower clamp 12 each include a pair of clamping rollers 102 and a support housing 103. The clamping rollers 102 are mounted on the support housing 103. The upper clamp 11 is provided with a positioning control mechanism 4, which is used to control the end of the goods clamping.

[0041] The rotating part 3, which drives the positioning clamping part 1 to rotate, includes a rotating ring 30, which is fixedly connected to the positioning clamping part 1 and rotatably connected to the support base 31. The upper clamp 11 and the lower clamp 12 are respectively fixedly connected to two positioning rods 32. The positioning rods 32 move along the positioning guide rail 33, and the two positioning rods 32 can be fixed on the positioning guide rail 33 when not moving. The middle part of the positioning guide rail 33 is fixed to the output shaft of the motor 34, that is, the center of the positioning guide rail 33 coincides with the center of the output shaft of the motor 34. The motor 34 is connected to the adaptive component 5, which drives the motor 34 to rise and fall, so that the rotation center of the motor 34 can coincide with the midpoint of the line connecting the centers of the upper clamp 11 and the lower clamp 12, so as to realize the concentric rotation of the positioning clamping part 1 and the motor 34.

[0042] This invention features a mobile trolley 10 and a positioning clamping part 1. The mobile trolley 10 automatically loads and unloads goods, while the positioning clamping part 1 clamps the goods, ensuring that the goods are clamped without being damaged, thus improving clamping stability. The positioning clamping part 1 can also be rotated by the rotating part 3 to adjust the posture of the goods, avoiding manual handling and improving the degree of automation. Furthermore, this invention can adjust the rotation center of the rotating part 3 to coincide with the center of the clamped goods, thereby making it suitable for goods of various sizes.

[0043] The upper clamp 11 and the lower clamp 12 are arranged symmetrically, and the two pairs of clamping rollers 102 are also symmetrical after clamping is completed.

[0044] The present invention ensures that the center of the line connecting the upper clamp 11 and the lower clamp 12 coincides with the rotation center of the motor 34, that is, the center of the goods coincides with the center of the motor 34.

[0045] The positioning and clamping part 1 of the present invention can be symmetrically arranged in two sets, and those skilled in the art can set multiple sets according to the size of the goods and the actual use scenario.

[0046] For further explanation of this example, refer to Figures 5-6 The clamping roller 102 is fixed to one end of the connecting rod 106, and the other end of the connecting rod 106 is threadedly connected to the first bolt 107. The first bolt 107 is inserted into the threaded hole 108. Multiple threaded holes 108 are formed on the connecting plate 109, and the connecting plate 109 is connected to the support housing 103.

[0047] When adjusting the spacing of the clamping rollers 102, the upper and lower pairs of clamping rollers 102 need to be adjusted synchronously to maintain the same spacing and ensure that the center position of the goods does not change.

[0048] By adjusting the position of the clamping roller 102, the present invention can reduce or increase the distance between the two clamping rollers 102, thereby clamping goods of different sizes.

[0049] In the lower clamp 12, the connecting plate 109 inside is fixedly connected to the support housing 103 in the lower clamp 12.

[0050] For further explanation of this example, refer to Figures 1-4The conveyor 2 includes a first hydraulic cylinder 104, the output end of which is fixed to the lower clamp 12. The lower clamp 12 is fixedly connected to the sliding assembly 20. The sliding assembly 20 includes a guide slider 21 and a guide rail 22. The guide slider 21 is fixed to the lower clamp 12 and moves along the guide rail 22. The guide rail 22 is fixed to the support frame 101. The upper clamp 11 is connected to the support frame 101.

[0051] The present invention uses the output end of the first hydraulic cylinder 104 to move the lower clamp 12 from bottom to top along the support frame 101, the upper clamp 11 is fixed on the support frame 101, and the lower clamp 12 lifts the goods up to clamp them with the upper clamp 11.

[0052] The upper clamp 11 is fixedly connected to the support frame 101.

[0053] For further explanation of this example, refer to Figures 8-11 The positioning control mechanism 4 includes a first support rod 41 and a second support rod 42. One end of each of the first support rod 41 and the second support rod 42 passes through the clamping roller 102, which is hollow inside. The other ends of the first support rod 41 and the second support rod 42 are respectively fitted into a sleeve 43 and move along it. One end of a spring 44 is fixed to the other end of each of the first support rod 41 and the second support rod 42. The other end of the spring 44 is fixed to the bottom of the sleeve 43. The sleeve 43 is fixed to the clamping roller 102. Support rod 41 and second support rod 42 are staggered. The first support rod 41 is horizontally arranged, and the second support rod 42 is inclined. The first support rod 41 is fixed to the inclined guide rod 45. The inclined guide rod 45 moves along the inclined guide hole 46 on the third support rod 47. The third support rod 47 moves along the straight guide hole 48 opened on the clamping roller 102. The third support rod 47 can connect with the pressure sensor 105 on the placement plate 49. The pressure sensor 105 is electrically connected to the drive mechanism 13 through a processor. The placement plate 49 is fixed on the clamping roller 102.

[0054] During operation, the goods are placed between the two clamping rollers 102 on the lower clamp 12. The lower clamp 12 lifts the goods up to overlap with the clamping rollers 102 of the upper clamp 11, thus clamping the goods together. The second support rod 42 on the two clamping rollers 102 of the upper clamp 11 retracts first after contacting the goods. Then, the first support rod 41 retracts after contacting the goods, causing the third support rod 47 to move longitudinally. When the third support rod 47 moves to overlap with the pressure sensor 105, the pressure sensor 105 controls the first hydraulic cylinder 104 to close through the processor, thus ending the clamping.

[0055] Multiple sets of the first support rod 41 and the second support rod 42 are arranged radially along the clamping roller 102. Similarly, multiple sets of sleeves 43, springs 44, inclined guide rods 45, and third support rods 47 are also provided to cooperate with them.

[0056] This invention can address the problem of uneven surfaces on goods causing varying degrees of extension of the third support rod 47. Only when at least half of the multiple sets of third support rods 47 are engaged with the pressure sensor 105 can the clamping be determined to be complete.

[0057] The length of the first support rod 41 is greater than the length of the second support rod 42.

[0058] In this invention, the second support rod 42 contacts the goods first, increasing the effective contact area during clamping and ensuring clamping stability. The first support rod 41 contacts the goods later, ensuring that the pressure sensor 105 can be triggered. In order to ensure that the extension and retraction of the third support rod 47 is not affected by the undulation of the goods surface, the length of the first support rod 41 is slightly larger than that of the second support rod 42.

[0059] The bottom of the sleeve 43 may be provided with a limiting block to restrict the extension and retraction length of the first support rod 41 and the second support rod 42, so that the first support rod 41 and the second support rod 42 can extend and retract within a limited length.

[0060] In order to increase the clamping area and ensure that the first support rod 41 can retract to trigger the pressure sensor 105, in the initial state, when the goods are on the lower clamp 12, the lowest point of the goods is below the center of the clamping roller 102.

[0061] Among them, such as Figure 1 As shown, when two sets of positioning clamping parts 1 are symmetrically arranged, the moving trolley 10 can respectively grab two goods and place them into the positioning clamping parts 1. After clamping, the two goods can also be aligned. For example, after flange pipe fittings are clamped and aligned, the two flange pipe fittings can be connected together by bolts. Therefore, the present invention can not only achieve clamping, but also centering.

[0062] For further explanation of this example, refer to Figures 1-2 The adaptive component 5 includes a second hydraulic cylinder 8, the output end of which is fixed to a fixed plate 81. The fixed plate 81 is fixed to the motor 34. An elongated hole 82 is opened on the positioning guide rail 33, and a positioning hole 83 is opened on the positioning rod 32. A fixing component 9 is installed in the elongated hole 82 and the positioning hole 83.

[0063] In this embodiment, the upper clamp 11 and the support frame 101 are fixedly connected. When the goods are clamped, the rotation center of goods of different sizes will be located at different heights. By setting the adaptive component 5, the present invention can enable the upper clamp 11 and the lower clamp 12 to move freely up and down during the clamping process. When the clamping ends, the upper clamp 11 and the lower clamp 12 are fixed on the positioning guide rail 33. By adjusting the height of the motor 34, the rotation center of the motor 34 is made to coincide with the rotation center of the clamped goods, so that the rotating part 3 drives the positioning clamping part 1 to rotate.

[0064] The fixing component 9 consists of a bolt and a nut.

[0065] Example 2:

[0066] Based on Embodiment 1, the upper clamp 11 and the support frame 101 are no longer fixedly connected, as shown in the following example. Figures 8-9 Specifically, the sliding assembly 20 is provided in two sets. One set of the sliding assembly 20 is connected to the upper clamp 11 through the adjustment assembly 6. The adjustment assembly 6 includes a support plate 61. One side of the support plate 61 is fixed to the guide slider 21, and the other side of the support plate 61 is fixed to the limiting guide rail 62. Limiting blocks 63 are fixed at both ends of the limiting guide rail 62. The limiting guide rail 62 has a limiting slider 64 that moves along it. The limiting slider 64 is fixed to the support housing 103 in the upper clamp 11. The support plate 61 is fixed to the rack 65. The rack 65 meshes with the gear 66. The gear 66 is coaxially fixed to the lead screw 67. The lead screw 67 is bearing connected inside the support housing 103. The lead screw 67 is provided with two sections of threads with opposite directions. Two guide sleeves 68 are fitted on the lead screw 67. The two guide sleeves 68 are fixedly connected to the two connecting plates 109 respectively.

[0067] During operation, the lower clamp 12 lifts the goods upward and moves them upward. As the goods push the upper clamp upward, the upper clamp 11 can move upward along the limit guide rail 62 and stop at the upper limit block 63. At the same time, the gear 66 moves upward along the rack 65, thereby driving the lead screw 67 to rotate, causing the two guide sleeves 68 to move towards each other, causing the two clamping rollers 102 in the upper clamp 11 to move towards each other, clamping the goods, and triggering the pressure sensor 105 to end the clamping and centering.

[0068] This invention, by adding an adjustment component 6, avoids the first support rod 41, the second support rod 42, and the third support rod 47 from being jammed or broken due to the rapid rise of the lower clamp 12, which would affect the use of the pressure sensor 105. The adjustment component 6 enables the goods to bear the weight of the upper clamp 11, allowing the upper clamp 11 to move upward, reducing impact force, optimizing the clamping process, thereby improving the fault tolerance rate and clamping centering efficiency. Furthermore, this invention is also applicable to goods of various sizes.

[0069] In this design, the distance A between the two clamping rollers 102 in the upper clamp 11 is greater than the distance B between the two clamping rollers 102 in the lower clamp 12. When the centering is finished, the distance A is equal to the distance B, which ensures that the spatial position of the rotation center of goods of different sizes can be effectively determined so that the subsequent rotating part 3 can drive the positioning clamping part 1 to rotate.

[0070] Example 3:

[0071] The difference between this embodiment and Embodiments 1 and 2 is that the upper clamp 11 and the lower clamp 12 can move towards each other, as shown in the figure. Figures 5-6 Specifically, the conveyor 2 further includes a first sprocket 23 and a second sprocket 24. The first sprocket 23 and the second sprocket 24 are connected to the support frame 101 by bearings. The first sprocket 23 and the second sprocket 24 are driven by a chain 25. One side of the chain 25 is fixed to the support plate 61, and the other side of the chain 25 is fixed to the support housing 103 in the lower clamp 12, so as to realize that the upper clamp 11 and the lower clamp 12 move towards each other.

[0072] During operation, the lower clamp 12 is raised by the first hydraulic cylinder 104, and the lower clamp 12 drives the chain 25 to rotate along the first sprocket 23 and the second sprocket 24, thereby causing the upper clamp 11 to descend and jointly clamp the goods.

[0073] The present invention improves the efficiency of logistics transportation by moving the upper clamp 11 and the lower clamp 12 toward each other, thereby increasing the speed of clamping goods.
