In the initial state, the transfer vehicle is fixedly connected to the adjustment plate, and the adjustment plate is located at the position closest to the first mounting seat; the first power assembly drives the mounting frame to swing above the incoming material conveying device, and the second power assembly drives the second mounting seat to rotate, and under the coordinated action of the first power assembly and the second power assembly, one side of the first mounting seat is opposite to the incoming material conveying device, and the permanent magnetic suction cup on this side of the second mounting seat adsorbs the first longitudinal beam, and then the second power assembly drives the first mounting seat to rotate 180°, and under the coordinated action of the first power assembly and the second power assembly, the other side of the second mounting seat is opposite to the incoming material conveying device, and the permanent magnetic suction cup installed on the other side of the second mounting seat adsorbs the second The first power assembly drives the mounting frame to swing to the top of the transfer vehicle, and under the coordinated action of the first power assembly and the second power assembly, the second mounting seat places the first longitudinal beam on the transfer vehicle, and then the third power assembly controls the transmission of the first gear and the first rack, so that the transfer vehicle moves a distance of the width of the longitudinal beam in the direction away from the first mounting seat; the second power assembly controls the second mounting seat to rotate 180°, and under the coordinated action of the first power assembly and the second power assembly, the second mounting seat places the second longitudinal beam on the transfer vehicle, thereby realizing the placement of the two longitudinal beams, improving the efficiency of longitudinal beam unloading, and realizing the neat and orderly placement of the longitudinal beams.

[0017] Since the second mounting base includes a first connecting frame fixedly connected to the second rotating shaft, and second connecting frames installed at both ends of the first connecting frame, a driving mechanism for driving the two second connecting frames to move toward or away from each other is installed on the first connecting frame, and the permanent magnetic suction cup is installed on the second connecting frame, and the driving mechanism is used to drive the two second connecting frames to move toward or away from each other, so that during the adsorption process of the longitudinal beam and the permanent magnetic suction cup, the adsorption position of the permanent magnetic suction cup and the longitudinal beam is more accurate and more stable after grasping.

[0018] Since the driving mechanism includes a third rotating shaft, the second rotating shaft is a hollow shaft, the third rotating shaft is sleeved in the hollow shaft, a fourth power assembly driving the third rotating shaft to rotate is installed on the second connecting frame, a second gear is coaxially fixed on the third rotating shaft, a first through hole and a second through hole are provided at both ends of the first connecting frame, a first guide rod is slidably installed in the first through hole, a second guide rod is slidably installed in the second through hole, the first guide rod and the second guide rod are both fixedly connected to the second connecting frame, and a second rack meshing with the second gear is provided on the first guide rod.

The second power assembly 310 drives the second rotating shaft 311 to rotate through the transmission mechanism 312 , and the transmission mechanism 312 includes a worm wheel coaxially fixed on the second rotating shaft 311 , and a worm rotatably mounted on the mounting frame 31 , and the worm is meshed with the worm wheel.

[0035] The storage and transfer device 2 includes a detachably connected transfer vehicle 20 and an adjustment plate 21. In this embodiment, the transfer vehicle 20 and the adjustment plate 21 are fixed by a plug 201. Casters 200 are installed at the bottom of the transfer vehicle 20 and the adjustment plate 21, so that the transfer vehicle 20 and the adjustment plate 21 can walk on the ground. A first rack 210 is installed at the bottom of the adjustment plate 21. The extension direction of the first rack 210 is consistent with the walking direction of the transfer vehicle 20 or the adjustment plate 21. A third mounting seat 22 is provided below the adjustment plate 21. The third mounting seat 22 is installed with a first gear 220 and a third power assembly. The third power assembly drives the first gear 220 to rotate. The first gear 220 is meshed with the first gear 220, so that the first gear 220 rotates, driving the adjustment plate 21 to move, thereby driving the transfer vehicle 20 to move synchronously. Among them, the first power assembly 300, the second power assembly 310 and the third power assembly are all stepping motors or servo motors electrically connected to the controller.

[0036] When in use, in the initial state, the transfer vehicle 20 is fixedly connected to the adjustment plate 21, and the adjustment plate 21 is located closest to the first mounting seat 30;

[0037] The first power assembly 300 drives the mounting frame 31 to swing to the top of the incoming material conveying device 1, and the second power assembly 310 drives the second mounting seat to rotate. Under the coordinated action of the first power assembly 300 and the second power assembly 310, one side of the first mounting seat 30 is directly opposite to the incoming material conveying device 1, and the permanent magnetic suction cup 34 on the side of the second mounting seat adsorbs the first longitudinal beam 4, and then the second power assembly 310 drives the first mounting seat 30 to rotate 180°. Under the coordinated action of the first power assembly 300 and the second power assembly 310, the other side of the second mounting seat is directly opposite to the incoming material conveying device 1, and the permanent magnetic suction cup 34 installed on the other side of the second mounting seat adsorbs the second longitudinal beam 4, thereby completing the grabbing of the two longitudinal beams 4;

[0038] The first power assembly 300 drives the mounting frame 31 to swing to the top of the transfer vehicle 20. Under the coordinated action of the first power assembly 300 and the second power assembly 310, the second mounting seat places the first longitudinal beam 4 on the transfer vehicle 20. Then the third power assembly controls the transmission of the first gear 220 and the first rack 210, so that the transfer vehicle 20 moves a distance of the width of the longitudinal beam 4 in the direction away from the first mounting seat 30. The second power assembly 310 controls the second mounting seat to rotate 180°. Under the coordinated action of the first power assembly 300 and the second power assembly 310, the second mounting seat places the second longitudinal beam 4 on the transfer vehicle 20, thereby realizing the placement of two longitudinal beams 4, improving the efficiency of the longitudinal beam 4 unloading, and realizing the neat and orderly placement of the longitudinal beams 4.

[0039] After placing a layer of longitudinal beams 4 on the transfer vehicle 20, the third power assembly drives the transfer vehicle 20 to return to the initial position and starts to place the next layer of longitudinal beams 4. After the transfer vehicle 20 places several layers of longitudinal beams 4, the connection between the transfer vehicle 20 and the adjustment plate 21 is dismantled so that the transfer vehicle 20 can be transferred to the next process.

[0040] Furthermore, the feeding direction of the incoming material conveying device 1 is consistent with the axial direction of the first rotating shaft 301 or the second rotating shaft 311 , so that the longitudinal beam 4 can be clamped more conveniently.

[0041] Preferably, the second mounting base includes a first connecting frame 32 and a second connecting frame 33, the middle position of one side of the first connecting frame 32 is fixed on the end face of the second rotating shaft 311, and the second connecting frame 33 is connected to the two opposite end faces of the first connecting frame 32 along the radial direction of the second rotating shaft 311 through a driving mechanism, and the permanent magnetic suction cup 34 is fixedly installed on the end of the second connecting frame 33 facing away from the first mounting frame 31; the driving mechanism is used to drive the two second connecting frames 33 to move toward or away from each other, so that during the adsorption process of the longitudinal beam 4 and the permanent magnetic suction cup 34, the adsorption position of the permanent magnetic suction cup 34 and the longitudinal beam 4 is more accurate and more stable after grasping.

[0042] Preferably, the driving mechanism includes a third rotating shaft 320, the second rotating shaft 311 is a hollow shaft, the third rotating shaft 320 is sleeved in the hollow shaft, and a fourth power assembly 321 is installed on the second connecting frame 33. The fourth power assembly 321 is preferably a servo motor or a stepping motor, and the fourth power assembly 321 is used to drive the third rotating shaft 320 to rotate;

[0043] A second gear 322 is coaxially fixed to the third rotating shaft 320, and a first through hole and a second through hole are provided at both ends of the first connecting frame 32. A first guide rod 330 is slidably installed in the first through hole, and a second guide rod 331 is slidably installed in the second through hole. The first guide rod 330 and the second guide rod 331 are both fixedly connected to the second connecting frame 33, and a second rack 332 meshing with the second gear 322 is provided on the first guide rod 330. The movement of the second connecting frame 33 is realized by the synchronous sliding of the first guide rod 330 and the second guide rod 331. The transmission of the second gear 322 and the second rack 332 makes the fourth power assembly 321 drive the third rotating shaft 320 to rotate forward or reverse, thereby driving the reciprocating movement of the second connecting frame 33, thereby realizing the two second connecting frames 33 moving toward or away from each other.

[0044] Furthermore, a first guide rod 330 installed on a second connecting frame 33 is arranged opposite to a second guide rod 331 installed on another second connecting frame 33, and a sliding hole 333 is provided on the second rack 332 for plugging into the second guide rod 331. The second guide rod 331 slides in the sliding hole 333, thereby further improving the stability and strength of the structure.

[0045] Furthermore, the two second racks 332 are symmetrically connected to the two sides of the second gear 322 , that is, one second gear 322 synchronously drives the two second racks 332 to move synchronously, thereby improving the accuracy of the movement of the two second racks 332 .

[0046] Furthermore, a sliding groove 323 is provided in the first connecting frame 32 , and the second rack 332 is slidably connected in the sliding groove 323 , thereby improving the sliding stability of the second rack 332 .

[0047] Furthermore, at least two third through holes are provided on the second connecting frame 33, and a third guide rod 340 is slidably connected in the third through hole. One end of the third guide rod 340 is fixed to the permanent magnetic suction cup 34, and the other end of the third guide rod 340 is screwed with a limiting nut 342. The third guide rod 340 is sleeved with a compression spring 341 elastically supported between the permanent magnetic suction cup 34 and the second connecting frame 33. Through the elastic action of the compression spring 341, the permanent magnetic suction cup 34 changes from hard contact to elastic contact when adsorbing the longitudinal beam 4, thereby reducing the wear of the permanent magnetic suction cup 34.

[0048] Furthermore, the top surface of the adjustment plate 21 is lower than the bottom surface of the transfer vehicle 20 , so that the combination of the transfer vehicle 20 and the adjustment plate 21 is more convenient, and the synchronous movement of the adjustment plate 21 and the transfer vehicle 20 is more stable.

[0049] Furthermore, a limit block 211 is provided at the bottom of the adjustment plate 21, and the limit block 211 is used to block against two sides of the third mounting seat 22, so that the adjustment plate 21 can only move back and forth within a distance range, thereby preventing the adjustment plate 21 from being separated from the first gear 220. The present invention is not limited to the above specific implementation methods, and various changes made by ordinary technicians in this field based on the above conception without creative labor are all within the protection scope of the present invention.
