[0025] The medium inside the second sealing cylinder 20, the first through tube 18, the second through tube 19 and the first sealing cylinder 15 is liquid or gas. Liquid is not easily compressed and has better pressure bearing effect, while gas is easily compressed and is not suitable for bearing products with larger mass.

[0026] Working principle: In this solution, a trigger module 33 is fixedly arranged at the end of the reversing docking frame 3, and its position distribution is as shown in the attached figure. Figure 2 As shown in , the function of the trigger module 33 is that when the tray 4 is transported to the top of the reversing docking frame 3 and abuts against the inner wall of the reversing docking frame 3, the trigger module 33 will be triggered, and the trigger module 33 can drive the electric push rod 13 to carry the optical axis 14 to reciprocate once; The first motor 11 and the second motor 12 are always in operation. In the initial state, the second rotating shaft 7 is in a raised state with the second conveying wheel 8, and the upper horizontal sections of the plurality of second conveying wheels 8 are in the same horizontal plane as the contact surface of the first conveying line body 1 for carrying and transporting the pallet 4, that is, the first conveying line body 1 can be seamlessly connected to transport the pallet 4 to the top of the plurality of second conveying wheels 8 inside the reversing docking frame 3, and when the pallet 4 touches the trigger module 33, the output end of the electric push rod 13 moves upward with the optical axis 14 first, and then resets downward, and in the process of moving upward, the medium inside the second sealing cylinder 20 located below the second straight frame 10 will be drawn into the first sealing cylinder 15, and at this time, under the action of the spring 22, the connecting rod 23 will move the second straight frame 10 downward by an end distance, that is, the second rotating shaft 7 and the second conveying wheel 8 will drop slightly; When the first piston 16 moves upward, the medium above it will be transported to the inside of the second sealing cylinder 20 located below the first straight frame 9 through the first through pipe 18. At this time, the second piston 21 located inside the second sealing cylinder 20 will rise, and the first straight frame 9 will be raised through the connecting rod 23, that is, the first rotating shaft 5 and the first conveying wheel 6 will rise slightly; By replacing the second conveying wheel 8 with the first conveying wheel 6, the bottom of the pallet 4 located above the reversing docking frame 3 is only in contact with the first conveying wheel 6 and not in contact with the second conveying wheel 8. By driving the first motor 11, the first conveying wheel 6 can be used to transfer the pallet 4 to the second conveying line body 2, thereby completing the reversing transfer operation of the pallet 4.

[0027] In this solution, the reversing docking frame 3 occupies a small area and is more suitable for the reversing transfer requirements in a small space. It also has high stability for the reversing transfer of the pallet 4 and will not cause the pallet 4 to fluctuate, thereby ensuring the stability of the products in the pallet 4.

[0028] It is worth noting that the time for the electric push rod 13 to reciprocate once each time the trigger module 33 is touched is sufficient to complete the reversing and transferring work of the tray 4 . Example 2: Please refer to Figure 7-Figure 9 This embodiment is a further description of the first embodiment. The partition unit includes a sliding plate 27 located below the first rotating shaft 5 and the second rotating shaft 7, and a plurality of push rods 28 equidistantly distributed in a straight line are fixedly provided on the top of the sliding plate 27. The push rods 28 are distributed between the adjacent second conveying wheels 8 and the first conveying wheels 6. A driving component is also provided between the sliding plate 27 and the optical axis 14. When the sliding plate 27 can move upward with the push rods 28, the trays 4 that are close to each other can be separated.

[0029] The driving component includes a gear differential 24 fixedly arranged at the bottom of the reversing docking frame 3, and a transmission gear 25 is fixedly sleeved on the input end of the gear differential 24, a rack 17 is fixedly arranged at the bottom of the optical axis 14, and the rack 17 is movably engaged with the transmission gear 25, and a limit sleeve 26 is axially slidably sleeved on the outside of the sliding plate 27, and the limit sleeve 26 is fixed on the inner side of the reversing docking frame 3, an arc through groove 31 is opened inside the limit sleeve 26, and a straight groove 32 is opened inside the sliding plate 27, and the output end of the gear differential 24 faces the limit sleeve 26. A transmission shaft 35 is fixedly provided at the output end of the gear differential 24, and the transmission shaft 35 is rotatably assembled on the end face of the limit sleeve 26, and a turntable 29 is also fixedly mounted on the outer surface of the transmission shaft 35, and a column 30 is fixedly inserted inside the turntable 29, and the column 30 is movably and slidably embedded in the arc groove 31 and the straight groove 32. Every time the optical axis 14 moves back and forth, the gear differential 24 can be triggered through the meshing of the rack 17 and the transmission gear 25, so that the transmission shaft 35 can rotate with the turntable 29, and at this time the column 30 can lift the sliding plate 27.

[0030] A chamfered portion 34 is provided on the bottom outer surface of the tray 4, the top of the push rod 28 is in an oblique arc shape, and the oblique arc end face of the push rod 28 faces the first conveyor line body 1. The design of the chamfered portion 34 makes it easier to separate two trays 4 that are close to each other when the push rod 28 moves upward.

[0031] In this embodiment: when the optical axis 14 starts to move upward, the gear differential 24 can be triggered by the action of the rack 17 and the transmission gear 25, so that the transmission shaft 35 can rotate with the turntable 29. The column 30 is eccentrically arranged inside the turntable 29. When the turntable 29 rotates a certain angle, the column 30 can lift the sliding plate 27 through the action of the straight groove 32. It should be noted that the turntable 29 and the arc groove 31 are coaxially distributed, and the arc groove 31 can ensure the stability of the movement of the column 30. Due to the continuous operation of the first conveyor line body 1, when the first tray 4 abuts against the inner wall of the reversing docking frame 3, the second tray 4 will be closely attached to the first tray 4, and when the sliding plate 27 moves upward, the push rod 28 pushes the chamfered portion 34 at the bottom of the tray 4, so that the second tray 4 can be separated from the first tray 4, thereby playing a temporary isolation role for the first tray 4; It should be noted that the rotation speed of the turntable 29 can be changed by the action of the gear differential 24, so that when the first conveying wheel 6 has not yet contacted the bottom of the first pallet 4, the push rod 28 has already separated the first pallet 4, thereby ensuring that when the first pallet 4 is reversing and transferring, the following pallet 4 will not squeeze through under the operation of the first conveyor line 1, thereby avoiding the pallet 4 from being stuck in the upper part of the reversing docking frame 3.

[0032] Through the function of the partition unit, it is possible to transfer the pallet 4 on the first conveyor line body 1 to the second conveyor line body 2 without frequently stopping the first conveyor line body 1.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
