Description

Technical Field

[0001] This invention relates to the field of warehousing technology, and in particular to a cargo temporary storage system. Background Technology

[0002] With the rapid development of modern manufacturing and logistics, the temporary storage and transfer of goods off the production line has become a crucial link in supply chain management. Cardboard boxes, as a common form of packaging, directly impact overall logistics efficiency and operational safety through their stacking, temporary storage, and loading processes after production.

[0003] Currently, the downstream processing of the production line mainly relies on manual operation: after the cartons are output from the sorting conveyor, workers manually carry them to a designated temporary storage area for stacking; when the transport vehicle arrives, the stacked cartons are then manually moved one by one into the vehicle and re-stacked. Some improved solutions have introduced simple conveyor devices in the conveying process, but core steps such as stacking goods in the temporary storage area, planning transfer routes, and loading still require manual intervention. This operation method not only requires a large manpower input, but also results in low overall efficiency due to repetitive handling. In addition, manually handling heavy cartons poses occupational safety hazards such as falls and injuries, and muscle strain.

[0004] Under current technological conditions, although automated conveying equipment has been widely used at the front end of the production line, there is still a lack of complete automated solutions for temporary storage areas and loading processes that require flexible handling. In particular, when dealing with complex scenarios such as mixed stacking of cartons of different sizes, dynamic temporary storage area management, and vehicle-adaptive loading, existing technologies still heavily rely on manual judgment and operation, making it difficult to achieve fully automated operation. Summary of the Invention

[0005] The purpose of this invention is to provide a cargo temporary storage system to alleviate the technical problems of low cargo temporary storage efficiency and high risk caused by the need for manual loading, temporary storage and unloading of existing cardboard boxes.

[0015] Furthermore, the shipping device includes a transfer mechanism that transfers goods from the shelf to the shipping conveyor by negative pressure pulling or pushing / pulling.

[0016] Furthermore, the shipping device includes a liftable second longitudinal transport platform and a liftable transfer mechanism. When the second longitudinal transport platform is raised to a second height position, it can dock with the input end of the shipping conveyor and transport the goods to the shipping conveyor. By adjusting the height of the second longitudinal transport platform and aligning the height of the transfer mechanism with the height of the goods on the second longitudinal transport platform, the transfer mechanism can transfer goods from a shelf at any height to the second longitudinal transport platform.

[0017] Furthermore, the transfer mechanism is a second pushing mechanism, which is used to push the goods from the rear side of the goods forward along the lateral direction onto the second longitudinal transport platform.

[0019] Furthermore, the second pushing mechanism includes a third linear drive module and a second pusher plate. The moving end of the third linear drive module is connected to the second pusher plate to drive the second pusher plate to move laterally and push the goods.

[0020] Furthermore, the second pushing mechanism also includes a fourth linear drive module, which is disposed between the third linear drive module and the second push plate. The fourth linear drive module drives the second push plate to move longitudinally, and the third linear drive module drives the fourth linear drive module and the second push plate to move laterally together.

[0029] Goods can be placed into a receiving conveyor, which automatically transports them to an inbound unit. The inbound unit then places the goods onto a shelf at the inbound location. A transfer mechanism carries the shelf containing the goods and transports it to a temporary storage location. The transfer mechanism then unloads the shelf to prepare for the next shelf. Upon receiving a shipping instruction, the transfer mechanism moves to the area beneath the corresponding shelf, carries it, and moves it to the shipping location.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0035] Example 1 like Figure 1 and Figure 2 As shown, the cargo temporary storage system provided by the present invention is suitable for the temporary storage of various goods, such as cardboard boxes, and is applied in warehousing environments.

[0036] The system includes a receiving and conveying mechanism 100, which can be a roller conveyor or a belt conveyor. The receiving and conveying mechanism 100 (including a transfer and turning mechanism, which is prior art) transports cartons to a designated position. The transfer and turning mechanism can adjust the placement direction of the cartons (length → width) to adapt to the storage requirements of the material rack.

[0037] In this embodiment, the loading device 200 includes a first pushing mechanism 220, which is used to push goods onto the shelf 300. The loading device 200 is located on the opposite side of the shelf 300 to be loaded, and drives the push plate to push the goods onto the shelf 300 through lateral telescopic movement.

[0038] In this embodiment, the shelf 300 is a single-layer shelf, that is, it is equipped with only one shelf 310 that allows goods to be placed on it. The height of the shelf 310 is approximately the same as the height of the receiving and conveying mechanism 100, and the loading device 200 can directly push the goods on the receiving and conveying mechanism 100 onto the shelf 310.

[0039] like Figure 1 As shown, the transfer mechanism 400 can include AGVs (Automated Guided Vehicles), configured with multiple navigation methods (laser / vision / magnetic strip optional), and supports various vehicle configurations such as stealthy / forklift / towing. Working principle: Based on a preset map or real-time environmental perception, it autonomously plans paths and accurately connects to various storage locations within the rack 300, receiving location, shipping location, and temporary storage location, achieving automatic transfer of full / empty racks 300. When multiple AGVs work together, a scheduling system avoids conflicts, improving transfer efficiency, unlike the rigid mode of fixed-track transfer in existing technologies.

[0040] The shipping device 500 transfers the goods on the shelf 300 at the shipping position to the shipping conveyor 600. Finally, the goods are removed from the system by the shipping conveyor 600 and then connected to a manual telescopic belt conveyor or an automatic loading equipment to complete the loading, achieving a seamless connection between shipping and loading.

[0041] Among them, the shipping conveyor 600 and the receiving conveyor 100 have the same conveying type.

[0042] like Figure 2 As shown, the first pushing mechanism 220 includes a first linear drive module 221 and a first push plate 222. The moving end of the first linear drive module 221 is connected to the first push plate 222 to drive the first push plate 222 to move laterally and push the goods. The first linear drive module 221 may include a lead screw motor module or a cylinder telescopic module.

[0043] like Figure 7 As shown, the shipping device 500 includes a transfer mechanism. In this embodiment, the transfer mechanism is a suction mechanism, which is used to pull goods from the front side of the shelf forward laterally onto the second longitudinal transport platform 510. The second longitudinal transport platform 510 is connected to the shipping conveyor 600, and goods can be transferred from the second longitudinal transport platform 510 to the shipping conveyor 600.

[0044] The suction mechanism includes a fifth linear drive module 550 and a negative pressure suction cup mechanism 560. The moving end of the fifth linear drive module 550 is connected to the negative pressure suction cup mechanism 560 to drive the negative pressure suction cup mechanism 560 to move laterally and suck up the goods.

[0045] The fifth linear drive module 550 drives the negative pressure suction cup mechanism 560 to approach the goods on the shelf 300. The negative pressure suction cup mechanism 560 is activated and sucks up the box. Then the fifth linear drive module 550 drives the negative pressure suction cup mechanism 560 away from the shelf 300, thereby removing the goods from the shelf 300 and completing the transfer of goods.

[0046] When the shelf 300 can hold at least two rows of goods, if the extension stroke of the fifth linear drive module 550 is insufficient to reach the furthest storage location on the shelf 300 from the second longitudinal transport table 510, the suction mechanism also includes a sixth linear drive module 570. The fifth linear drive module 550 is mounted on the moving end of the sixth linear drive module 570, so that the sixth linear drive module 570 drives the fifth linear drive module 550 and the negative pressure suction cup mechanism 560 to move laterally together. This achieves two-stage extension to meet the multi-depth storage needs of the shelf 300.

[0047] Specifically, the shipping device 500 includes a second support 580, which is mounted on the second longitudinal transport table 510. The sixth linear drive module 570 includes a second slide rail 571 and a second slider 572. The second slide rail 571 extends laterally and is connected to the second support 580, and the second slider 572 is slidably connected to the second slide rail 571. The fifth linear drive module may include a second scissor telescopic arm module or a second rigid chain telescopic arm module. In this embodiment, one end of the second scissor telescopic arm module is connected to the second slider 572, and the other end is connected to the negative pressure suction cup mechanism 560.

[0048] Initially, the second slider 572 is positioned away from the shelf 300, and the fifth linear drive module is in a shortened state. During retrieval, the second slider 572 moves towards the shelf 300, and the negative pressure suction cup mechanism 560 contacts the front row of the shelf 300. Figure 7 The goods on the left side are sucked up and the second slider 572 moves away from the shelf 300, the goods in the front row are removed, the negative pressure suction cup mechanism 560 releases the goods, and after the goods are transferred away, the second slider 572 moves towards the shelf 300 again. Then, the fifth linear drive module extends, so that the negative pressure suction cup mechanism 560 contacts the rear row of goods on the shelf 300. Figure 7The goods on the right side are then moved away from the shelf 300 by the fifth linear drive module, and the second slider 572 moves away from the shelf 300, dragging the goods in the back row off the shelf 300. This two-stage telescopic design avoids the problem of excessively long conveying distances caused by a single scissor-type linear drive module, which is prone to deformation after prolonged use due to the downward force of the negative pressure suction cup mechanism 560.

[0049] Furthermore, the shipping device includes an eighth linear drive module, and the second slide rail 571 is slidably connected to the second support along the longitudinal direction. There are multiple suction mechanisms and multiple eighth linear drive modules, arranged in a one-to-one correspondence, with the multiple suction mechanisms spaced apart along the longitudinal direction. The eighth linear drive module, such as an electric push rod, is used to drive the suction mechanism to move longitudinally on the second support, thereby changing the spacing between two adjacent suction mechanisms in the longitudinal direction to match the position of a row of goods on the corresponding shelf.

[0050] Example 2 like Figure 3 As shown, unlike the single-layer storage of goods in Embodiment 1, in this embodiment, the shelf 300 has multiple vertically arranged shelves 310, which can store multiple layers of goods simultaneously. The loading device 200 pushes the goods layer by layer onto the shelves 310 at different heights.

[0051] Specifically, the loading device 200 includes a liftable first longitudinal transport platform 210 and a liftable first pushing mechanism 220. Both the first longitudinal transport platform 210 and the first pushing mechanism 220 can move vertically. The loading device 200 includes a first lifting drive mechanism 230, such as a scissor lift, a telescopic cylinder lift, or a rigid chain lift. Both the first longitudinal transport platform 210 and the first pushing mechanism 220 are directly connected to the first lifting drive mechanism 230, which drives both to rise and fall simultaneously. Alternatively, the first longitudinal transport platform 210 is directly connected to the first lifting drive mechanism 230, and the first pushing mechanism 220 is located at the edge of the first longitudinal transport platform 210, which also allows the first longitudinal transport platform 210 and the first pushing mechanism 220 to rise and fall synchronously.

[0052] like Figure 3As shown, when the support surface of the first longitudinal transport platform 210 moves to a first height (the same height as the support surface of the receiving and conveying mechanism 100), the receiving and conveying mechanism 100 can directly transport goods onto the first longitudinal transport platform 210. Under the longitudinal transport of the first longitudinal transport platform 210, the goods are transported to a position directly opposite the first pushing mechanism 220. Then, the heights of the first longitudinal transport platform 210 and the first pushing mechanism 220 are adjusted to match the height of the first layer of the shelf, that is, after the first pushing mechanism 220 moves laterally, it can push the goods on the first longitudinal transport platform 210 onto the first shelf 310. Then, the first longitudinal transport platform 210 and the first pushing mechanism 220 fall back to the first height position, so that the goods on the receiving conveyor 100 can be transported to the first longitudinal transport platform 210 again. Then, the first longitudinal transport platform 210 and the first pushing mechanism 220 rise together, so that the supporting surface of the first longitudinal transport platform 210 can be flush with the second shelf 310, making it convenient to push the goods to the second shelf 310. In this way, the shelf 300 can be filled.

[0053] Example 3 like Figure 3 and Figure 4 As shown, the difference from Embodiment 2 is that in this embodiment, the loading device 200 includes a first lifting drive mechanism 230 and a second lifting drive mechanism 240, the first longitudinal transport platform 210 is connected to the first lifting drive mechanism 230, and the first pushing mechanism 220 is connected to the second lifting drive mechanism 240.

[0054] In other words, the first longitudinal transport platform 210 and the first pushing mechanism 220 are no longer driven by the same lifting mechanism, but are driven by the first lifting drive mechanism 230 and the second lifting drive mechanism 240 respectively. Therefore, the first pushing mechanism 220 is not set on the first longitudinal transport platform 210, and the height of the first pushing mechanism 220 can be adjusted independently, so that the first pushing mechanism 220 can match cartons of different heights, so that the contact position between the first pushing mechanism 220 and the cartons is approximately at the vertical center of the cartons, avoiding the first pushing mechanism 220 failing to contact cartons that are too low during the pushing process, or the pushing position being located on the lower side of the cartons, causing the cartons to tip over during the pushing process.

[0055] The connection method between the first longitudinal transport platform 210 and the first lifting drive mechanism 230 in the loading device 200 is the same as in Embodiment 2, and will not be described again. The second lifting drive mechanism 240 may include a gantry frame and a crossbeam that can be lifted relative to the gantry frame (the vertical drive module of the crossbeam may be a screw motor module or a cylinder lifting module), and the first pushing mechanism 220 is disposed on the crossbeam.

[0056] Example 4 When the shelf 300 can hold at least two rows of goods, if the extension stroke of the first linear drive module 221 is insufficient to reach the furthest storage location on the shelf 300 from the first longitudinal transport table 210, such as Figure 5 As shown, unlike 1-3, the first pushing mechanism 220 in this embodiment also includes a second linear drive module 223. The first linear drive module 221 is disposed on the moving end of the second linear drive module 223, so that the second linear drive module 223 drives the first linear drive module 221 and the first push plate 222 to move laterally together, thereby realizing two-stage extension and retraction to meet the storage needs of more than 300 deep positions of the temporary storage rack.

[0057] The first linear drive module 221 and the second linear drive module 223 may have the same or different structural forms.

[0058] In this embodiment, the first pushing mechanism 220 includes a first support 224, which is connected to and located above the first longitudinal transport platform 210. A second linear drive module 223 is fixedly connected to the first support 224. The second linear drive module 223 is suspended above the support surface of the first longitudinal transport platform 210 to avoid interference with the goods during loading.

[0059] The second linear drive module 223 may include a lead screw motor module, which includes a first slide rail 2231 and a first slider 2232. The first slide rail 2231 extends laterally and is connected to the top of the first bracket 224. The first slider 2232 is slidably connected to the first slide rail 2231, meaning the first slider 2232 can move laterally. The first linear drive module 221 may include a first scissor telescopic arm module or a first rigid chain telescopic arm module. In this embodiment, one end of the first scissor telescopic arm module is connected to the first slider 2232, and the other end is connected to the first push plate 222.

[0060] During the box pushing process, initially, the first linear drive module 221 is in its shortest state, and the first slider 2232 is located in the first slide rail 2231 away from the shelf 300. When a box moves to the front of the first push plate 222, the first slider 2232 moves laterally to the end of the first slide rail 2231 closer to the shelf 300. During this process, the goods on the first longitudinal transport table 210 are pushed to the position on the shelf 300 closer to the first longitudinal transport table 210 (front row). Then, the first linear drive module 221 extends, driving... The first pusher plate 222 continues to move forward, thereby pushing the goods in the front row of the shelf 300 to a position in the shelf 300 away from the first longitudinal transport platform 210 (the rear row). Then, the first linear drive module 221 and the second linear drive module 223 return to their initial positions. When goods are transported to the front of the first pusher plate 222 again, the goods can be pushed to the front row of the shelf 300 using only the first linear drive module 221 or the second linear drive module 223, thus realizing the placement of goods in two rows on the same layer of the shelf 300. Furthermore, in this embodiment, a two-stage push / pull method is adopted to avoid the problem of excessively long conveying and deformation of the linear drive module after long-term use due to the downward force of the first pusher plate 222.

[0061] Example 5 like Figure 6 As shown, the difference from Embodiment 1 is that the first pushing mechanism 220 in this embodiment includes both a first linear drive module 221 and a second linear drive module 223 to achieve two-stage pushing. Its specific structure has been described in Embodiment 4 (Embodiment 5 corresponds to the single-layer shelf 300), and will not be repeated here.

[0062] Example 6 like Figure 8 As shown, the difference from Embodiment 1 is that in this embodiment, the transfer mechanism does not use a negative pressure method, but a push plate method, and it can be matched with the shipment of multi-layer shelves.

[0063] Specifically, the shipping device 500 includes a liftable second longitudinal transport platform 510 and a liftable transfer mechanism. When the second longitudinal transport platform 510 is raised to a second height position (matching the height of the support surface of the shipping conveyor 600), it can dock with the input end of the shipping conveyor 600 and transport the goods longitudinally to the shipping conveyor 600. The second longitudinal transport platform 510 and the first longitudinal transport platform can have the same or different structures.

[0064] By adjusting the height of the second longitudinal transport platform 510 and making the height of the transfer mechanism consistent with the height of the goods on the second longitudinal transport platform 510, the transfer mechanism can transfer the goods on the shelf 310 of any height to the second longitudinal transport platform 510 to complete the shipment of multi-layer racks.

[0065] The transfer mechanism is a second pushing mechanism 520. In this embodiment, the second pushing mechanism 520 is placed on the rear side of the shelf, while the second longitudinal transport platform 510 is located on the front side of the shelf. The second pushing mechanism 520 is used to push goods laterally forward from the rear side onto the second longitudinal transport platform 510. The specific structure of the second pushing mechanism 520 can be the same as the first pushing mechanism in Embodiment 1. The second pushing mechanism 520 includes a third linear drive module 521 and a second push plate 522. The moving end of the third linear drive module 521 is connected to the second push plate 522 to drive the second push plate 522 to move laterally and push the goods.

[0066] The shipping device 500 includes a third lifting drive mechanism 530 and a fourth lifting drive mechanism 540. The second longitudinal transport platform 510 is connected to the third lifting drive mechanism 530, and the second pushing mechanism 520 is connected to the fourth lifting drive mechanism 540. In order to match the shelves of different heights on the rack, in this embodiment, the third lifting drive mechanism 530 and the fourth lifting drive mechanism 540 are used to lift the second longitudinal transport platform 510 and the second pushing mechanism 520, respectively. The third lifting drive mechanism 530 can also be a scissor lift device, while the fourth lifting drive mechanism 540 has the same structure as the second lifting drive mechanism 240 in embodiment 2.

[0067] Example 7 Unlike Embodiment 6, in this embodiment, the second pushing mechanism 520 is located on the side of the shelf instead of the rear, thereby enabling the pushing of goods from both the front and rear rows on the shelf.

[0068] Specifically, the second pushing mechanism 520 also includes a fourth linear drive module, which is located between the third linear drive module 521 and the second push plate 522. The fourth linear drive module drives the second push plate 522 to move longitudinally, and the third linear drive module 521 drives the fourth linear drive module and the second push plate 522 to move laterally together.

[0069] First, the third linear drive module 521 drives the fourth linear drive module and the second pusher plate 522 to move laterally to the gap between the front and rear rows of goods. Then, the fourth linear drive module drives the second pusher plate 522 to move longitudinally between the front and rear rows of goods. Finally, the third linear drive module 521 drives the fourth linear drive module and the second pusher plate 522 to move laterally, pushing the goods in the front row off the shelf. Then, the third linear drive module 521 and the fourth linear drive module drive the second pusher plate to move behind the goods in the rear row, pushing the goods in the rear row off, completing the unloading of the goods in both rows.

[0070] Example 8 like Figure 9 As shown, the difference from Embodiment 1 is that in this embodiment, the shipping device 500 includes a third lifting drive mechanism 530; the second longitudinal transport platform 510 and the suction mechanism are both connected to the third lifting drive mechanism 530, or the second longitudinal transport platform 510 is connected to the third lifting drive mechanism 530, and the suction mechanism is connected to the second longitudinal transport platform 510, so that the second longitudinal transport platform 510 and the suction mechanism have the same lifting state, thereby removing goods from multi-layer shelves.

[0071] Example 9 like Figure 10 As shown, unlike the picking mechanism in Embodiment 1, the transferring mechanism in this embodiment is a forklift mechanism. Specifically, the forklift mechanism includes a retractable first telescopic arm 710 and a retractable second telescopic arm 720. The first telescopic arm 710 and the second telescopic arm 720 extend laterally and are spaced apart longitudinally to avoid obstructing goods. Rotatable levers 730 are provided at the ends of the first telescopic arm 710 and the second telescopic arm 720, and the pivot of the lever 730 is arranged laterally.

[0072] Initially, both the first telescopic arm 710 and the second telescopic arm 720 are in their shortest positions, and the lever 730 on both arms rotates to a vertical position to avoid interference with the goods when they extend. When retrieving goods, the first and second telescopic arms 710 and 720 extend simultaneously, passing through the longitudinal sides of the goods. Extension stops when the lever 730 reaches the rear of the goods. Then, the lever 730 rotates to a horizontal position. Next, the first and second telescopic arms 710 and 720 shorten simultaneously, and the lever 730 abuts against the rear of the goods, pulling them off the temporary storage rack 300, completing the transfer of goods from the rack 300.

[0073] The first telescopic boom 710 and the second telescopic boom 720 can be multi-segment telescopic booms.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
