Abstract

The application relates to the technical field of automatic stereoscopic warehouse, and discloses an automatic multi-angle stacking type stereoscopic warehouse, which comprises a goods shelf part, a stacking walking mechanism, a lifting mechanism, a goods carrying mechanism and a guardrail mechanism. The goods carrying mechanism is designed in a bidirectional telescopic mode. Telescopic driving elements can drive telescopic supporting tables and telescopic goods plates to synchronously telescopically extend along both sides of the supporting table in a bidirectional mode. The goods stacking and taking operation on the two sides of the goods shelf part can be quickly realized without driving the stacking walking mechanism to turn around or adjusting the position, the disadvantages that the traditional stacking machine can only take goods on one side and needs to repeatedly adjust the equipment for taking and storing goods on the two sides are completely solved, the operation time is greatly shortened, and the storage and taking efficiency is improved compared with the traditional single-side goods taking and stacking machine. Meanwhile, the guardrail mechanism is designed in a telescopic mode driven by an electric telescopic rod. When transporting, the guardrail one and the guardrail two form a surrounding protection to prevent the goods from sliding.

Description

Technical Field

[0001] This invention relates to the field of automated storage and retrieval systems (AS / RS), specifically to an automated multi-angle stacking AS / RS. Background Technology

[0002] With the rapid development of smart logistics and industrial automation, automated storage and retrieval systems (AS / RS) have become widely used in various fields such as manufacturing, e-commerce logistics, and cold chain warehousing due to their advantages of high space utilization, high storage and retrieval efficiency, and low labor costs. However, existing stacking AS / RS still face several technical challenges in practical applications, making it difficult to meet the needs of industry development. These challenges are as follows: 1. Most mainstream stacker cranes currently use a unidirectional telescopic design for their loading mechanisms, which can only push and retrieve goods in a single direction perpendicular to the aisle, and can only perform storage and retrieval operations on shelves on one side of the aisle. When it is necessary to stack or retrieve goods from shelves on the other side of the aisle, the entire stacker crane must be driven to move along the guide rails to the corresponding side aisle, or the stacker crane's posture must be adjusted to perform a turning operation. This is not only cumbersome and time-consuming, but also significantly reduces the efficiency of goods turnover. 2. Although some stacker cranes have attempted to use multi-stage telescopic forks to achieve long-distance cargo pushing, the telescopic actions of each stage are mostly driven independently, lacking a precise synchronous transmission mechanism. This can easily lead to problems such as asynchronous telescopic movement and uneven load distribution, which not only reduces the storage and retrieval speed, but also causes the forks to deform and be damaged due to uneven force, thus affecting the service life of the equipment. 3. Most existing cargo platforms adopt a design without guardrails. This design poses a safety hazard of goods slipping during transportation and cannot balance ease of operation with warehouse safety.

[0003] In summary, there is an urgent need for an automated, multi-angle stacking warehouse that can enable bidirectional picking of goods by the loading mechanism and adapt to shelves on both sides. Summary of the Invention

[0004] The purpose of this invention is to provide an automated multi-angle stacking warehouse to solve the problems mentioned in the background art, such as the inability of existing automated warehouses to perform bidirectional stacking and retrieval of goods on both sides of the shelves and poor protection.

[0011] As a preferred embodiment of the automated multi-angle stacking three-dimensional warehouse of the present invention, the telescopic drive component is fixedly connected to the inner mounting cavity. The telescopic drive component includes a servo drive motor three, a transmission wheel, a belt, a driven wheel, and a gear one.

[0012] As a preferred embodiment of the automated multi-angle stacking three-dimensional warehouse described in this invention, the telescopic platform is slidably connected within the mounting slot. The telescopic platform includes a platform plate, a gear mounting port, a rack, a gear, a rack, an I-beam, a reinforcing support plate, and a guide pulley. The rack is fixedly connected to the bottom of the platform plate, and the gear meshes with the rack. The gear mounting port is located on the platform plate, and the gear is rotatably connected within the gear mounting port. The rack is fixedly connected within the mounting slot of the platform and meshes with the gear. The I-beam is fixedly connected to the upper surface of the platform plate, and the reinforcing support plate is fixedly connected within the mounting slot of the platform.

[0013] As a preferred embodiment of the automated multi-angle stacking three-dimensional warehouse of the present invention, the telescopic pallet is slidably connected to the top of the platform one.

[0014] As a preferred embodiment of the automated multi-angle stacking three-dimensional warehouse of the present invention, the guardrail mechanism includes a base plate, an electric telescopic rod, a first guardrail, and a second guardrail. The base plate is fixedly connected to both ends of the platform, the electric telescopic rod is fixedly connected to the base plate, the first guardrail is fixedly connected to the telescopic end of the electric telescopic rod, and the second guardrail is fixedly installed on the upper surface of the platform.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The loading mechanism adopts a two-way telescopic design. The telescopic drive unit can drive the telescopic platform and telescopic pallet to extend and retract synchronously in both directions along both sides of the platform. This eliminates the need to drive the stacking travel mechanism to turn around or adjust its position, enabling rapid stacking and retrieval of goods on both sides of the aisle. This completely solves the drawbacks of traditional stacker cranes that can only retrieve goods from one side and require repeated adjustments for both sides, significantly shortening operation time and improving retrieval efficiency compared to traditional single-side retrieval stacker cranes. Simultaneously, the two-stage synchronous telescopic structure, combining the telescopic platform and telescopic pallet, ensures long-distance pushing while avoiding uneven force distribution and action delays caused by independent drives.

[0016] The guardrail mechanism adopts an electric telescopic rod driven telescopic design. During transportation, the first guardrail drops down to form a closed enclosure with the second guardrail to prevent the goods from slipping. When picking up and storing goods in both directions, the first guardrail moves up to make way for the picking openings at both ends of the platform. This does not interfere with the telescopic picking actions on both sides, and can take into account both transportation safety and operational convenience, thus solving the drawback of traditional guardrails interfering with picking up goods.

[0017] The traveling support adopts a dual-sided support structure with front and rear pulleys and an inner locking mechanism with I-beam guide rails, completely eliminating the risk of derailment during movement. Simultaneously, a limit guide wheel at the top of the upright clamps an L-shaped limit rod, forming a top guiding constraint. Combined with the sliding connection between the slide cylinder and the upright, this effectively suppresses horizontal swaying during lifting. During bidirectional retrieval, the lifting mechanism can precisely adjust its height to accommodate the storage and retrieval needs of different layers on both sides of the shelving, improving operational convenience. Precise control of servo drive motor one and servo drive motor two, combined with mechanical limits, achieves coordinated movement and lifting. This, along with the bidirectional extension and retraction of the loading mechanism, meets the rapid operation requirements of shelving on both sides in high-density warehousing.

[0021] This invention provides a technical solution: such as Figure 1 - Figure 13 An automated multi-angle stacking warehouse is shown, including a rack section 100. The rack section 100 is composed of several supporting vertical rods 110, reinforcing horizontal rods 120, stacking rods 130, and L-shaped limiting rods 140. The supporting vertical rods 110 are arranged in a vertical array, the reinforcing horizontal rods 120 are horizontally connected to adjacent supporting vertical rods 110, the stacking rods 130 are fixed to the supporting vertical rods 110, and the L-shaped limiting rods 140 are located at the top of the supporting vertical rods 110. The warehouse also includes: The stacking and traveling mechanism 200 includes a guide rail 210, a traveling seat 220, and a stop 230. The guide rail 210 is laid horizontally on the ground and located between two sets of shelving sections 100. The stop 230 is fixedly connected to both ends of the guide rail 210, and the traveling seat 220 is slidably connected to the guide rail 210. The lifting mechanism 300 includes a column 310, a slide cylinder 320, a lifting chain 330, and a top limiting rod 340. The column 310 is fixedly connected to the traveling seat 220 in the vertical direction. The slide cylinder 320 is slidably sleeved on the outside of the column 310. The lifting chain 330 is installed on one side of the column 310 and connected to the slide cylinder 320. The top limiting rod 340 is fixedly installed on the upper end of the column 310 and connected to the L-shaped limiting rod 140. The cargo-carrying mechanism 400 includes a platform 410, a telescopic drive component 420, a telescopic support platform 430, and a telescopic cargo plate 440. The platform 410 is fixedly connected to the slide cylinder 320. The telescopic drive component 420 is installed inside the platform 410. The telescopic support platform 430 is disposed on the platform 410. The telescopic cargo plate 440 is disposed on the platform 410 and connected to the telescopic support platform 430. Guardrail mechanism 500 is mounted on platform 410.

[0022] In some embodiments of the present invention, reference is made to... Figure 3 - Figure 4As shown, the cargo rack 130 includes an L-shaped rod 131, a corner block 132, and a baffle 133. The L-shaped rod 131 is fixedly connected to the supporting vertical frame rod 110 through the corner block 132, and the baffle 133 is fixedly connected to the rear end of the L-shaped rod 131.

[0023] In some embodiments of the present invention, reference is made to... Figure 5 - Figure 7 As shown, the walking seat 220 includes a base 221, a front pulley 222, a rear pulley 223, a retaining wheel 224, and a servo drive motor 225. The front pulley 222 and the rear pulley 223 are rotatably mounted at both ends of the base 221, and the retaining wheel 224 is rotatably connected to the bottom of the base 221 and engages with the guide rail 210. The guide rail 210 has an I-shaped structure, and the retaining wheel 224 is engaged with the inner side of the guide rail 210. The servo drive motor 225 is fixedly connected to the base 221, and the output end of the servo drive motor 225 is connected to the front pulley 222 for transmission.

[0024] When the servo drive motor 225 is started, the output shaft of the servo drive motor 225 drives the front pulley 222 to rotate clockwise in the forward direction. The front pulley 222 generates friction with the wing plate of the guide rail 210, driving the walking seat 220 to move along the guide rail 210 towards the target shelf column. During the movement, the rear pulley 223 rotates synchronously with the walking seat 220, providing auxiliary support and ensuring the horizontal stability of the walking seat 220. The locking roller 224 is engaged with the inner groove of the guide rail 210, always rolling against the inner wall of the groove to prevent derailment. At the same time, the limiting guide wheel 342 of the top limiting rod 340 rolls against the vertical plate end of the corresponding L-shaped limiting rod 140, further assisting in guidance and suppressing the swaying of the column 310 during movement.

[0025] In some embodiments of the present invention, reference is made to... Figure 7 - Figure 9 As shown, the lifting chain 330 includes a housing 331, a lower sprocket 332, an upper sprocket 333, a transmission chain 334, a second servo drive motor 335, and a connector 336. The housing 331 is fixedly connected to one side of the column 310. The lower sprocket 332 and the upper sprocket 333 are rotatably connected to the bottom and top of the housing 331, respectively. The transmission chain 334 is meshed between the lower sprocket 332 and the upper sprocket 333. The second servo drive motor 335 is fixedly connected to the bottom of the housing 331, and the output end of the second servo drive motor 335 is connected to the lower sprocket 332. The connector 336 is fixedly connected to the transmission chain 334. The housing 331 has a clearance strip for the connector 336 to be exposed. The connector 336 is fixedly connected to the slide cylinder 320.

[0026] The top limiting rod 340 includes an arm 341 and a limiting guide wheel 342. The arm 341 is fixedly connected to the top of the column 310, and the limiting guide wheel 342 is rotatably connected to both ends of the arm 341. Two sets of limiting guide wheels 342 are installed at each end, and the vertical plate end of the L-shaped limiting rod 140 is sandwiched between the two sets of limiting guide wheels 342.

[0027] The servo drive motor 335 is started, and its output shaft drives the lower sprocket 332 to rotate clockwise. The lower sprocket 332, through meshing transmission, drives the transmission chain 334 to circulate between the lower sprocket 332 and the upper sprocket 333. The upward section of the transmission chain 334 drives the connecting piece 336 to move upward. As the connecting piece 336 moves upward, it drives the slide cylinder 320 to slide vertically upward along the column 310. The slide cylinder 320 and the column 310 are fitted with a clearance to ensure smooth sliding without jamming. Simultaneously, the limiting guide wheel 342 of the top limiting rod 340 rolls along the vertical end of the L-shaped limiting rod 140 on the target side. Two sets of limiting guide wheels 342 at each end symmetrically clamp the L-shaped limiting rod 140, effectively suppressing the horizontal swaying of the slide cylinder 320 and the column 310, ensuring a stable lifting process.

[0028] In some embodiments of the present invention, reference is made to... Figure 10 - Figure 13 As shown, the platform 410 includes a mounting slot 411, an inner mounting cavity 412, and an inspection door 413. The mounting slot 411 is located at the upper end of the platform 410, the inner mounting cavity 412 is located inside the platform 410, and the inspection door 413 is hinged to the side wall of the platform 410 and communicates with the inner mounting cavity 412.

[0029] The telescopic drive component 420 is fixedly connected to the inner mounting cavity 412. The telescopic drive component 420 includes a servo drive motor 421, a transmission wheel 422, a belt 423, a driven wheel 424, and a gear 425. The output end of the servo drive motor 421 is fixedly connected to the transmission wheel 422. The belt 423 is sleeved between the transmission wheel 422 and the driven wheel 424. The gear 425 is coaxially fixedly connected to the driven wheel 424. The shaft end of the driven wheel 424 extends out from the inner mounting cavity 412. The gear 425 is set in the mounting slot 411.

[0030] The telescopic support 430 is slidably connected within the mounting slot 411. The telescopic support 430 includes a platform 431, a gear mounting port 401, a rack 432, a gear 433, a rack 434, an I-beam 435, a reinforcing support plate 436, and a guide pulley 437. The rack 432 is fixedly connected to the bottom of the platform 431. The gear 425 meshes with the rack 432. The gear mounting port 401 is located on the platform 431. Gear 2 433 is rotatably connected to the gear mounting port 401. Rack 2 434 is fixedly connected to the mounting slot 411 of the platform 410 and meshes with gear 2 433. I-beam 435 is fixedly connected to the upper end face of the platform 1 431. Reinforcing support plate 436 is fixedly connected to the mounting slot 411 of the platform 410. Guide pulley 1 437 is rotatably connected to the upper end of the reinforcing support plate 436 and rolls against one side of the I-beam 435.

[0031] The telescopic cargo platform 440 is slidably connected to the top of the platform 431. The telescopic cargo platform 440 includes a platform 441, a rack 442, a reinforcing wheel 443, and a guide pulley 444. The rack 442 is fixedly connected to the bottom of the platform 441 and meshes with the gear 433. The reinforcing wheel 443 is fixedly connected to the bottom of the platform 441. The guide pulley 444 is rotatably connected to the reinforcing wheel 443 and rolls against the other side of the I-beam 435.

[0032] The servo drive motor 3 421 of the loading mechanism 400 is started. The output shaft of the servo drive motor 3 421 drives the transmission wheel 422 to rotate clockwise to pick up goods on the right or counterclockwise to pick up goods on the left. The transmission wheel 422 drives the driven wheel 424 to rotate synchronously through the belt 423. The driven wheel 424 drives the coaxial fixed gear 1 425 to rotate synchronously. The rotation direction of gear 1 425 is the same as that of driven wheel 424.

[0033] When gear 425 rotates, it meshes with rack 432 for transmission. Since rack 432 is fixed to the bottom of platform 431, the rotation of gear 425 is converted into linear movement of platform 431 along mounting slot 411 toward the target side shelf 100, realizing the first extension of telescopic platform 430. During the extension process, the I-beam 435 at the bottom of platform 431 rolls against the guide pulley 437 on the reinforcing support plate 436. The guide pulley 437 plays a guiding and supporting role, reducing the friction between the I-beam 435 and the reinforcing support plate 436, ensuring that platform 431 extends smoothly without jamming or tilting. At the same time, gear 433 inside platform 431 meshes with rack 434 fixed in mounting slot 411 of platform 410. Since rack 434 is fixed, gear 433 rotates as platform 431 moves.

[0034] When gear 2 433 rotates, it meshes with rack 3 442 fixed to the bottom of platform 2 441, driving platform 2 441 to move linearly along the upper end of platform 1 431 toward the target side shelf 100, realizing the secondary extension of telescopic pallet 440; since the rotation speed of gear 2 433 is matched with the moving speed of platform 1 431, telescopic pallet 440 and telescopic support 430 extend and retract synchronously; during the extension process, guide pulley 2 444 on the reinforcing wheel plate 443 at the bottom of platform 2 441 rolls and abuts against the other side of I-beam 435, further improving the stability of extension and retraction, while preventing platform 2 441 from deviating.

[0035] In some embodiments of the present invention, reference is made to... Figure 10 and Figure 12 As shown, the guardrail mechanism 500 includes a base plate 510, an electric telescopic rod 520, a first guardrail 530, and a second guardrail 540. The base plate 510 is fixedly connected to both ends of the platform 410, the electric telescopic rod 520 is fixedly connected to the base plate 510, the first guardrail 530 is fixedly connected to the telescopic end of the electric telescopic rod 520, and the second guardrail 540 is fixedly installed on the upper surface of the platform 410.

[0036] The guardrail mechanism 500 adopts a telescopic design driven by an electric telescopic rod 520. During transportation, guardrail 1 530 falls down to form a protective enclosure with guardrail 2 540 to prevent goods from slipping. When picking up and storing goods in both directions, guardrail 1 530 moves up to make way for the picking openings at both ends of the platform 410. This does not interfere with the telescopic picking actions on both sides, and can take into account both transportation safety and operational convenience, thus solving the drawback of traditional guardrails interfering with picking up goods.
