Description

Technical Field

[0001] The present invention relates to warehousing technology, and in particular to an automated three-dimensional warehouse for e-commerce logistics. Background Art

[0002] Automated high-bay warehouses (AHWs) are a new concept in logistics and warehousing. Using AHW equipment, they streamline warehouse levels, automate storage and retrieval, and simplify operations; they represent a state-of-the-art technology. The AHW system consists of racks, aisle-mounted stacking cranes, inbound and outbound workstations, and automated inbound and outbound control systems. Racks are steel or reinforced concrete structures containing standard-sized cargo spaces. Aisle-mounted stacking cranes navigate the aisles between the racks, storing and retrieving goods. Computers and barcode technology are used for management.

[0003] In the prior art, shelves are all fixed-size cargo spaces. Although this method is convenient for aisle stackers to pick up and place goods, in some special circumstances, the cargo space that cannot be changed will show great limitations in use. For example, when placing some large and fragile items, it is not suitable to stack them. However, if only one layer of non-stacked goods is stored in the cargo space on the same floor, the top space with more cargo space will be vacant, resulting in serious space waste, which violates the purpose of high-definition warehouses to improve space utilization and reduce space occupancy. In addition, the storage flexibility is small, there are certain restrictions on the types of goods that can be stored, and it is difficult to cope with various types of warehousing needs.

Detailed implementation manners

[0031] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0032] Embodiment 1:

[0033] Please refer to Figures 1 - 9 , an automated three-dimensional warehouse for e-commerce logistics, including a plurality of groups of shelves 1 arranged at intervals and a conveying unit 101 adapted to the shelves 1. A picking and placing unit 102 adapted to the shelves 1 and the conveying unit 101 is arranged on one side of the shelves 1. The picking and placing unit 102 is used to place the goods on the conveying unit 101 on the shelves 1. The shelves 1 include four support rods 2 and a plurality of pallets 21 arranged between the four support rods 2;

[0034] A support plate 3 is installed between two support rods 2 on the same side. A lifting cylinder 31 is installed on the top of the support plate 3. The top of the telescopic end of the lifting cylinder 31 is fixedly connected to the pallet 21. A bearing unit is arranged between the pallet 21 and the support rod 2. The bearing unit is used to stably lift the pallet 21;

[0035] A limiting unit is arranged on the pallet 21. The limiting unit is used to restrict the adaptive movement of the goods.

[0036] In this embodiment, the bearing unit includes guiding grooves 4 respectively opened at the four corners of the pallet 21. A plurality of supporting grooves 41 are equidistantly arranged along the vertical direction on the side surfaces of the four support rods 2. A guiding slot 42 communicating with the inside of the guiding groove 4 is opened on the inner side surface of the pallet 21. A supporting toothed plate 43 is slidably connected to the inner side surface of the guiding slot 42. A driving gear 44 is rotatably connected to the inner side surface of the pallet 21. The driving gear 44 is driven by a motor.

[0037] Furthermore, all the supporting toothed plates 43 are engaged with the driving gear 44. The shape and dimensional specifications of the end of the supporting toothed plate 43 close to the supporting groove 41 are adapted to the supporting groove 41. When the driving gear 44 rotates, all the supporting toothed plates 43 move synchronously into the supporting groove 41, thereby facilitating the rapid positioning of the pallet 21. At the same time, when the driving gear 44 rotates in the reverse direction, the pallet 21 can be quickly disassembled.

[0038] In this embodiment, the limiting unit includes first straight grooves 5 symmetrically opened on both sides of the top of the pallet 21. A first limiting plate 51 is slidably connected to the inner side surface of the first straight groove 5. Second straight grooves 52 are symmetrically opened on both sides of the top of the pallet 21. A second limiting plate 53 is slidably connected to the inner side surface of the second straight groove 52. All the first limiting plates 51 and all the second limiting plates 53 are distributed in a rectangular shape on the top of the pallet 21.

[0039] Furthermore, the ends of all the first straight grooves 5 and all the second straight grooves 52 extend to be interconnected. A connecting frame 54 is slidably connected to the inner side surfaces of the first straight groove 5 and the second straight groove 52. Both the first limiting plate 51 and the second limiting plate 53 are connected to the connecting frame 54. When the connecting frame 54 moves upward along the inner walls of the first straight groove 5 and the second straight groove 52, all the first limiting plates 51 and all the second limiting plates 53 move upward synchronously. A receiving groove 55 corresponding to the first straight groove 5 is opened on the top of the pallet 21. A pressure-bearing block 56 is slidably connected to the inner side surface of the receiving groove 55. A support spring 57 is fixedly connected between the bottom of the pressure-bearing block 56 and the receiving groove 55. A toothed roller 58 is rotatably connected to the inner side surface of the pallet 21. Tooth grooves 59 adapted to the toothed roller 58 are opened on the side surfaces of the pressure-bearing block 56 and the first limiting plate 51. The toothed roller 58 is engaged with the tooth grooves 59, and the pressure-bearing block 56 and the first limiting plate 51 are respectively engaged on both sides of the toothed roller 58.

[0040] It should be added that the length value of the toothed roller 58 is the same as the length value of the pressure-bearing block 56, and the length value of the pressure-bearing block 56 is 1 / 4 of the width value of the pallet 21. When the pallet 21 carries goods of different dimensional specifications, the pressure-bearing block 56 can well bear the pressure on them and drive the first limiting plate 51 and the second limiting plate 53 to move upward to limit the movement of the goods.

[0041] During the use process, when goods with a relatively small size and height are placed on the pallet 21, the distance between the goods and the upper pallet 21 is relatively large. At this time, the driving gear 44 in the upper pallet 21 rotates, causing the internal supporting toothed plate 43 to move and withdraw from the inside of the supporting groove 41. Then, through the contraction of the telescopic end of the lifting cylinder 31 connected to the pallet 21, the pallet 21 moves downward, thereby adjusting the distance between the goods and the upper pallet 21, and greatly improving the internal space utilization rate of the automated warehouse.

[0042] When the goods are placed on the pallet 21, the pressure-bearing block 56 is pressed downward and compresses the support spring 57. Under the cooperation of the tooth grooves 59, the pressure-bearing block 56 moves downward to drive the tooth roller 58 to rotate, and drives the first limiting plate 51 to move upward. The movement of the first limiting plate 51 drives the connecting frame 54 to move, and the movement of the connecting frame 54 drives the second limiting plate 53 to move upward synchronously, so that the first limiting plate 51 can cooperate with the second limiting plate 53 to limit the movement of the goods, making the safety of the goods during storage better.

[0043] Embodiment 2:

[0044] Please refer to Figure 8 , this embodiment provides a technical solution on the basis of the above embodiment: The top of the connecting frame 54 is provided with adjusting grooves 6 corresponding to the first limiting plate 51 and the second limiting plate 53 respectively. The inner sides of the two groups of adjusting grooves 6 are respectively rotatably connected with a first bidirectional screw 61 and a second bidirectional screw 62. The first limiting plate 51 is threadedly connected with the first bidirectional screw 61, the second limiting plate 53 is threadedly connected with the second bidirectional screw 62, and the bottoms of the first limiting plate 51 and the second limiting plate 53 are respectively slidably connected with the inner sides of the corresponding adjusting grooves 6.

[0045] It should be noted that the first bidirectional screw 61 and the second bidirectional screw 62 are arranged vertically and staggeredly, and both the first bidirectional screw 61 and the second bidirectional screw 62 are driven by motors, so as to ensure the normal operation of the first bidirectional screw 61 and the second bidirectional screw 62 without interference.

[0046] During the working process, when storing goods of different sizes and specifications, by rotating and adjusting the first bidirectional screw 61 and the second bidirectional screw 62, the moving distances of the first limiting plate 51 and the second limiting plate 53 can be accurately controlled, so that the two first limiting plates 51 and the two second limiting plates 53 can flexibly adapt to the size requirements of different goods, ensuring that the goods are both stable and safe during storage, further improving the flexibility and practicality of the stereoscopic warehouse, and optimizing the logistics efficiency.

[0047] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
