Technical Field

[0001] The invention relates to a cargo storage system, in particular to an intelligent trolley three-dimensional storage system. Background Art

[0002] In existing warehouses, in order to save space, multi-layer shelves are used to place goods. When goods need to be picked up, the shelves are moved to the shipping position. The goal is to ship the goods as a whole shelf, which consumes useless electricity, is not flexible to move, and is difficult to improve efficiency. In addition, the utilization rate of the storage space is very limited.

[0003] In order to achieve efficient picking and high warehouse utilization rate, multiple material boxes need to be stacked to save storage space. In order to select and output the material boxes, a track frame needs to be set up, and a cargo transfer device needs to be set on the track. For multi-layer stacked goods, the cargo transfer device needs to be accurately moved to the top of the material box to be selected for grabbing. In this process, the grabbing mechanism needs to be accurately aligned with the target material box. Since the goods are usually stored in different positions, it is difficult to achieve timely switching of the working track in current technology so that the grabbing device can quickly move to the goods that need to be moved.

[0038] Refer to Figure 1 As shown, an alignment sensor 7 is provided between the side plate 341 of the transition track device 3 and the ends of the first and second running tracks, so that the transition track device 3 can be accurately aligned with the first running track 4 and the second running track 5.

[0039] The positioning sensor 7 is preferably a photoelectric sensor.

[0040] Reference Figure 5 , Figure 6 The structural diagram shown.

[0041] The lifting sub-body 2 comprises a moving platform 21 , a clamping claw 22 , and a guiding mechanism 23 . At least two lifting belts 24 are fixedly arranged on the moving platform 21 . A lifting wheel 15 is arranged in the running mother body 1 , and the lifting belts 24 are wound around the lifting wheel 15 .

[0042] In this embodiment, four slings 24 are preferably provided, and four lifting wheels 15 are respectively allocated thereto. The lifting wheels 15 are linked to the rotation of the motor to make the moving platform 21 rise or fall.

[0043] The clamping jaws 22 are a pair and are rotatably disposed on a side portion of the moving platform 21 . The moving platform 21 is provided with a stretching mechanism 25 for stretching and swinging the clamping jaws.

[0044] The stretching mechanism 25 is arranged at the center of the moving platform 21, and includes a rotating motor 251, a rotating disk 252 arranged at the output end of the rotating motor 251, and a pair of connecting rods 253 are rotatably arranged on the rotating disk, and the pair of connecting rods 253 are connected to the upper part of the clamping jaw 22. The rotating disk 252 is rotated by the motor 254, driving the pair of connecting rods 253 to stretch left and right, so that the clamping jaw 22 swings.

[0045] The lateral parts of the movable platform 21 are each provided with a rotating seat 26 , and a rotating shaft 27 is fixedly provided on the upper part of the clamping jaw 22 , and the rotating shaft 27 is rotatably provided in the rotating seat 26 .

[0046] In this embodiment, there are four guiding mechanisms 23 , which are disposed at the corners of the moving platform 21 .

[0047] The guiding mechanism 23 includes a stretching mechanism 231, a slide rail mechanism 232, and a guiding piece 233 extending vertically below the moving platform 21. The top of the guiding piece 233 is slidably connected to the moving platform 21 through the slide rail mechanism 232. The stretching mechanism 231 is used to link the top of the guiding piece 233 to slide along the slide rail mechanism 232 toward the center of the moving platform 21.

[0048] Preferably, the cross section of the guide member 233 is L-shaped.

[0049] The stretching mechanism 231 includes a stretching drive mechanism 2311, a connecting seat 2312, and a pull rod 2313. The connecting seat 2312 is fixedly arranged at the output end of the stretching drive mechanism 2311, and the two ends of the pull rod 2313 are rotatably connected to the connecting seat 2312 and the top of the guide 233. The stretching drive mechanism 2311 is an electric cylinder. In this embodiment, a groove 28 is arranged at the corner of the moving platform 21, and the top of the guide slides within the range of the groove.

[0050] Preferably, the two guide mechanisms 23 on the same side use the same stretching drive mechanism 2311.

[0051] In order to accurately position the running mother body 1 and the lifting child body 2, a positioning mechanism 8 is arranged between the moving platform 21 and the running mother body 1. The positioning mechanism 8 includes at least two positioning columns 81 fixedly arranged on the moving platform 21 and a female sleeve 82 fixedly arranged under the running mother body 1 and aligned with the positioning columns 81.

[0052] The operation process of the present invention is briefly described as follows:

[0053] The transition track device 3 is aligned with the first running track 4 through the alignment sensor 7, and the receiving drive mechanism 342 is actuated, so that the pulling wheel 345 and the clamping wheel 347 provided on the sliding plate 344 are connected to the first running track 4, ready to receive the pull rod 12.

[0054] The driving motor 113 of the transition track device 3 runs, causing the running mother body 1 to advance along the first running track 4. Under the action of the tapered introduction end 14, the pull rod 12 enters between the pulling wheel 345 and the clamping wheel 347. Under the action of the pulling drive mechanism 346, the pulling wheel 345 cooperates with the clamping wheel 347 to bring the pull rod 12 in between. After it is in place, the receiving drive mechanism 342 is reset. Driven by the driving motor 33, the transition track device 3 runs along the switching track 6 to the second running track 5 and aligns. Through the above process, the running mother body 1 enters the second running track 5 and completes the track change, so that the lifting sub-body 2 set under the running mother body 1 can be unloaded or loaded.

[0055] The track wheels 12 on the running mother body 1 run on the track to the top of the material frame to be lifted, and the lifting child body 2 is lowered by the lifting wheel 15 and the sling 24. In the initial state, the four guiding mechanisms 23 are all in the outward expansion state, that is, at the end of the slide rail mechanism 232. When the lifted child body 2 is lowered to the top of the material frame, the slide rail mechanism 232 is pulled by the stretching mechanism 231, so that the guiding member 233 slides and tightens toward the center of the moving platform 21, so that the moving platform 21 is directly above the material frame, and the stretching mechanism 25 drives the clamping claw 22 to swing, so that the ear of the clamping material frame below it can be moved upward, and the moving platform 21 is accurately located directly below the running mother body 1 through the alignment of the alignment mechanism 8, which is beneficial to prevent shaking during transportation.

[0056] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
