[0035] Exemplary embodiments of this application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are for teaching those skilled in the art how to implement this application only, and are not intended to exhaust all possible methods of this application, nor to limit the scope of this application.
[0036] Figures 1 to 8 A storage system according to an embodiment of this application is shown, with particular emphasis on a storage system for storing square bins 4 (examples of goods). The storage system may include a shelf 1, a first handling device 2, and a second handling device 3.
[0037] Reference Figures 1 to 3 Shelf 1 may include frame component 11, storage component 12, and buffer component 13. (See reference...) Figure 1 The frame assembly 11 may include columns 111, anchors 112, truss beams 113, connecting beams 114, span beams 115, storage layers 11a, and buffer layers 11b. Specifically, the columns 111, anchors 112, truss beams 113, connecting beams 114, and span beams 115 can be fixed to each other, for example, by fasteners. The columns 111 can extend vertically, and the anchors 112 can be located at the bottom of the columns 111 and fixed to the ground. Multiple columns 111 can be arranged at intervals, and every two columns 111 can form a group. Truss beams 113 can be arranged between one column 111 and another column 111 in each group of columns 111, and the columns 111 and truss beams 113 can be connected to form a truss structure. Connecting beams 114 and spanning beams 115 can extend horizontally and be arranged orthogonally to each other. Each connecting beam 114 and each spanning beam 115 can be located between one set of uprights 111 and another set of uprights 111 and connected to both sets of uprights 111. Multiple spanning beams 115 can be arranged at intervals in the vertical direction, so that the rack 1 is divided into multiple layers in the vertical direction. For example, the rack 1 can be divided into four layers, with the three higher layers being storage layers 11a and the bottom layer being a buffer layer 11b.
[0038] The storage assembly 12 may include a crossbeam, a limiting body, and a slide. Specifically, the crossbeam may include a guide portion for guiding the hopper 4 and a support portion for supporting the hopper 4. The crossbeam may be disposed on the storage layer 11a and supported by the crossbeam 115, and the crossbeam may extend horizontally and be arranged orthogonally to the crossbeam 115. For one storage layer 11a, multiple crossbeams may be parallel to each other and arranged side by side in the horizontal direction. Two adjacent crossbeams may define two slides, and the limiting body may be located between the two slides to separate them.
[0039] Reference Figure 2The structure of the storage component 12 will be further described below using the first crossbeam 121, the second crossbeam 122 and the third crossbeam 123 as examples. The configuration of the other crossbeams can be the same as the configuration described below.
[0040] The first crossbeam 121 may include a first guide portion 12a, a first support portion 12b, and a second support portion 12c. The cross-section of the first crossbeam 121 may be an inverted T-shape, the first guide portion 12a may be formed as a vertical portion of the T-shape, and the first support portion 12b and the second support portion 12c may be formed as horizontal portions of the T-shape. The first support portion 12b may be located on one side of the first guide portion 12a, and the second support portion 12c may be located on the other side of the first guide portion 12a. The thickness of the first guide portion 12a may be 10mm to 14mm. The first guide portion 12a may be vertically arranged, and the first support portion 12b and the second support portion 12c may be horizontally arranged and abut against the crossbeam 115. A first limiting body 124 and a third limiting body 126 may be disposed on the first guide portion 12a and fixed to the first guide portion 12a, for example, the first limiting body 124 and the third limiting body 126 may be welded to the first crossbeam 121. The first limiting body 124 may be positioned towards one side of the first guide portion 12a ( Figure 1 The third limiting body 126 protrudes to the other side of the first guide portion 12a (upper right side), and can move towards the other side of the first guide portion 12a. Figure 1 (The lower left side of the middle) protrusion.
[0041] The second crossbeam 122 may include a second guide portion 12d and a third support portion 12e. The cross-section of the second crossbeam 122 may be L-shaped, the second guide portion 12d may be formed as a vertical L-shaped portion, and the third support portion 12e may be formed as a horizontal L-shaped portion. The thickness of the second guide portion 12d may be 10mm to 14mm. The second guide portion 12d may be vertically arranged, and the third support portion 12e may be horizontally arranged and abut against the crossbeam 115. A second limiting body 125 may be provided on the second guide portion 12d and fixed to the second guide portion 12d, for example, the second limiting body 125 may be welded to the second crossbeam 122. The second limiting body 125 may protrude to the other side of the second guide portion 12d.
[0042] The third crossbeam 123 may include a third guide portion 12f, a fourth support portion 12g, and a fifth support portion 12h. The cross-section of the third crossbeam 123 may be an inverted T-shape, the third guide portion 12f may be formed as a vertical portion of the T-shape, and the fourth support portion 12g and the fifth support portion 12h may be formed as horizontal portions of the T-shape. The fourth support portion 12g may be located on one side of the third guide portion 12f, and the fifth support portion 12h may be located on the other side of the third guide portion 12f. The thickness of the third guide portion 12f may be 10mm to 14mm. The third guide portion 12f may be vertically arranged, and the fourth support portion 12g and the fifth support portion 12h may be horizontally arranged and abut against the crossbeam 115. The fourth limiting body 127 and the fifth limiting body 128 may be provided on the third guide portion 12f and fixed to the third guide portion 12f, for example, the fourth limiting body 127 and the fifth limiting body 128 may be welded to the third crossbeam 123. The fourth limiting body 127 can protrude to one side of the third guide portion 12f, and the fifth limiting body 128 can protrude to the other side of the third guide portion 12f.
[0043] The first crossbeam 121 and the second crossbeam 122 can define the first slide rail 12i and the third slide rail 12k, and the distance between the first crossbeam 121 and the second crossbeam 122 can be adapted to the width of the hopper 4. One end of the first slide rail 12i and one end of the third slide rail 12k can be arranged opposite to each other, and the other ends of the first slide rail 12i and the third slide rail 12k can be arranged opposite to each other. The first limiting body 124 and the second limiting body 125 can be located between one end of the first slide rail 12i and one end of the third slide rail 12k, such that the first slide rail 12i and the third slide rail 12k are separated by the first limiting body 124 and the second limiting body 125. Under the restriction of the first limiting body 124 and the second limiting body 125, the hopper 4 can only enter and exit the first slide rail 12i through the other end of the first slide rail 12i, and can only enter and exit the third slide rail 12k through the other end of the third slide rail 12k. The hopper 4, which enters the first slide rail 12i and the third slide rail 12k, can slide along the first slide rail 12i and the third slide rail 12k under the guidance of the first guide part 12a and the second guide part 12d. At the same time, the hopper 4 can abut against the first support part 12b and the third support part 12e, so that the first support part 12b and the third support part 12e can jointly support the hopper 4.
[0044] The first crossbeam 121 and the third crossbeam 123 can define the second slide rail 12j and the fourth slide rail 12m, and the distance between the first crossbeam 121 and the third crossbeam 123 can be adapted to the width of the hopper 4. One end of the second slide rail 12j and one end of the fourth slide rail 12m can be arranged opposite each other, and the other ends of the second slide rail 12j and the fourth slide rail 12m can be arranged away from each other. The third limiting body 126 and the fourth limiting body 127 can be located between one end of the second slide rail 12j and one end of the fourth slide rail 12m, such that the second slide rail 12j and the fourth slide rail 12m are separated by the third limiting body 126 and the fourth limiting body 127. Under the restriction of the third limiting body 126 and the fourth limiting body 127, the hopper 4 can only enter and exit the second slide rail 12j through the other end of the second slide rail 12j, and can only enter and exit the fourth slide rail 12m through the other end of the fourth slide rail 12m. The hopper 4, entering the second slide rail 12j and the fourth slide rail 12m, can slide along the second slide rail 12j and the fourth slide rail 12m under the guidance of the first guide part 12a and the third guide part 12f. At the same time, the hopper 4 can abut against the second support part 12c and the fourth support part 12g, so that the second support part 12c and the fourth support part 12g can jointly support the hopper 4.
[0045] Furthermore, when multiple crossbeams are arranged side by side, the crossbeam with an L-shaped cross section can be the first or last crossbeam in a row. For example, in this embodiment, the first crossbeam 122 and the third crossbeam 123 can have the same structure, and multiple first crossbeams 121 or multiple third crossbeams 123 can be located between two second crossbeams 122.
[0046] In this way, by sharing the first crossbeam 121 with the first slide rail 12i and the second slide rail 12j, a smaller gap can be achieved between the first slide rail 12i and the second slide rail 12j, allowing the rack 1 to achieve a higher storage density. With the same total volume of stored bins 4, the rack 1 can have a smaller volume, resulting in lower material costs. Furthermore, by providing supports on the crossbeam, the crossbeam can support the bins 4 while guiding their sliding. The rack 1 does not require additional components to support the bins 4, allowing for more compact vertical storage of the bins 4, further increasing storage density and reducing material costs.
[0047] By shaping the cross-section of the beam into a T-shape or L-shape, the guide portion can act as a guide while also serving as a reinforcing rib of the beam, giving the beam higher strength and thus enabling the shelf 1 to have a higher load-bearing capacity. Furthermore, by providing a third slide 12k that is opposite to the first slide 12i, the bins 4 can enter and exit the shelf 1 from two opposite directions. Even when the length of the beam is greater than the maximum length of the first telescopic mechanism 21 (see below), the first handling device 2 can still easily access the bins 4, allowing the beam to have a longer length, thereby increasing the storage capacity of a single shelf 1. Further, by separating the first slide 12i and the third slide 12k, the bins 4 in the first slide 12i and the third slide 12k will not collide with each other during sliding, preventing the bins 4 in the first slide 12i from being pushed out by the bins 4 in the third slide 12k, and vice versa, thus avoiding the risk of the bins 4 falling.
[0048] Reference Figure 3 and Figure 4 The cache component 13 may include a cache rack 131, a guide frame 132, an aisle 13a, and a QR code 13b. Specifically, the cache rack 131 may be disposed on the cache layer 11b, and may include a mounting portion 13c and a limiting portion 13d. The mounting portion 13c may be plate-shaped, and the limiting portion 13d may be disposed on the edge of the mounting portion 13c and protrude relative to the mounting portion 13c. The length of the mounting portion 13c may be adapted to the length of the material box 4, and the width of the mounting portion 13c may be less than the width of the material box 4. The mounting portion 13c may be horizontally fixed to the crossbeam 115, and multiple cache racks 131 may be arranged in two rows. The two rows of cache racks 131 may be spaced apart from each other, and the aisle 13a may be located between the two rows of cache racks 131 and run through the entire shelf 1. A corresponding cache position may be defined below each cache rack 131, and each cache position may be provided with a QR code 13b for distinguishing the cache rack 131.
[0049] The guide frame 132 can be fixed to the crossbeam 115, and every two guide frames 132 can correspond to one buffer frame 131. The two guide frames 132 can be spaced apart from each other in the width direction of the mounting part 13c, and the distance between the two guide frames 132 can be adapted to the width of the material box 4.
[0050] 5 Reference Figure 4 and Figure 5The first conveying device 2 can be an automated guided vehicle (AGV), which may include a suction cup, a first telescopic mechanism 21, a guide rail 22, a slider 23, and a first vehicle body 24. Specifically, the guide rail 22 can be fixed to the first vehicle body 24 and extend vertically, and the slider 23 can be mounted on the guide rail 22. The first telescopic mechanism 21 can be mounted on the slider 23, and the suction cup can be disposed at the end of the first telescopic mechanism 21. The first telescopic mechanism 21 can extend and retract in the horizontal direction, allowing the slider 23 and the suction cup to move closer and further apart in the horizontal direction.
[0051] Reference Figure 6 and Figure 7 The second handling device 3 can be an automated guided vehicle (AGV), which may include a pallet 31, a second telescopic mechanism 32, and a second vehicle body 33. Specifically, the second telescopic mechanism 32 can be installed on the second vehicle body 33, and the pallet 31 can be disposed at the end of the second telescopic mechanism 32. The second telescopic mechanism 32 can extend and retract in the vertical direction, so that the pallet 31 and the second vehicle body 33 can move closer to each other and further apart in the vertical direction.
[0052] The following describes the warehousing methods of the warehousing system, which generally include:
[0053] The goods are transported to the storage layer 11a by the first handling device 2;
[0054] The goods are moved from storage layer 11a to buffer layer 11b by the first handling device 2; and
[0055] The goods are removed from the buffer layer 11b by the second handling device 3.
[0056] Specifically, when it is necessary to store the material bin 4 on the shelf 1, the material bin 4 can be attracted by a suction cup, and the first vehicle body 24 can transport the material bin 4 to the target position next to the shelf 1. After the first vehicle body 24 reaches the target position, the slider 23 can move along the guide rail 22, so that the material bin 4 is lifted to the height corresponding to the storage layer 11a. Then, as... Figure 4 As shown, the first telescopic mechanism 21 can extend, allowing the material box 4 to enter the slide under the drive of the first telescopic mechanism 21. After the material box 4 has fully entered the slide, the suction cup can separate from the material box 4, and the first telescopic mechanism 21 can be shortened to its minimum length.
[0057] When it is necessary to distribute the tin 4 stored on shelf 1, the first conveying device 2 can remove the tin 4 from the slide rail using the first telescopic mechanism 21 and suction cups. After the tin 4 is removed, the slider 23 can move along the guide rail 22, so that the tin 4 is lowered to the height corresponding to the buffer layer 11b. Then, as... Figure 5As shown, the first telescopic mechanism 21 can extend, allowing the material box 4 to slide relative to the mounting portion 13c under the drive of the first telescopic mechanism 21 and the guidance of the guide frame 132. After the material box 4 is fully engaged with the mounting portion 13c, the material box 4 can just abut against the limiting portion 13d. Then, as... Figure 6 As shown, the second conveying device 3 can enter the channel 13a and move to the buffer position below the loading section 13c. The second telescopic mechanism 32 can extend, and the tray 31, driven by the second telescopic mechanism 32, can lift the hopper 4 from between the loading section 13c and the guide frame 132, thereby separating the hopper 4 from the loading section 13c. Figure 7 As shown, once the bottom of the material box 4 is higher than the top of the limiting part 13d, the material box 4 can leave the channel 13a together with the second conveying device 3.
[0058] Furthermore, the second conveying device 3 can distinguish different buffer racks 131 via QR code 13b, and can follow the instructions as follows: Figure 8 The path shown moves between different buffer positions, enabling the hopper 4 to be distributed efficiently. The second conveying device 3 can enter and exit the buffer position via a curved path.
[0059] This application has at least the following advantages.
[0060] (i) By sharing the first crossbeam 121 with the first slide rail 12i and the second slide rail 12j, a smaller gap can be achieved between the first slide rail 12i and the second slide rail 12j, enabling the rack 1 to achieve a higher storage density. With the same total volume of stored bins 4, the rack 1 can have a smaller volume, resulting in lower material costs. Furthermore, by providing supports on the crossbeam, the crossbeam can support the bins 4 while guiding their sliding. The rack 1 does not require additional components to support the bins 4, allowing for more compact vertical storage of the bins 4, further increasing storage density and reducing material costs.
[0061] (ii) By making the cross-section of the beam T-shaped or L-shaped, the guide part can serve as a reinforcing rib of the beam while playing a guiding role, so that the beam can have high strength, thereby giving the shelf 1 a high load-bearing capacity.
[0062] (iii) By setting a third slide 12k opposite to the first slide 12i, the bin 4 can enter and leave the shelf 1 from two opposite directions. Even when the length of the beam is greater than the maximum length of the first telescopic mechanism 21, the first handling device 2 can still easily access the bin 4, allowing the beam to have a longer length, thereby increasing the storage capacity of a single shelf 1.
[0063] (iv) By separating the first slide rail 12i and the third slide rail 12k, the hopper 4 in the first slide rail 12i and the hopper 4 in the third slide rail 12k will not collide with each other during the sliding process, so that the hopper 4 in the first slide rail 12i will not be pushed out by the hopper 4 in the third slide rail 12k, and the hopper 4 in the third slide rail 12k will not be pushed out by the hopper 4 in the first slide rail 12i, thereby avoiding the risk of the hopper 4 falling.
[0064] It should be understood that the above embodiments are merely exemplary and are not intended to limit this application. Those skilled in the art can make various modifications and changes to the above embodiments under the teachings of this application without departing from the scope of this application.
[0065] It should be understood that the crossbeam is not limited to having a T-shaped or L-shaped cross section. For example, the cross section of the crossbeam may be partially T-shaped or L-shaped, or may be formed in other shapes besides T-shaped and L-shaped.
