Description

Technical Field

[0001] This utility model relates to the field of stacker crane technology, specifically a stacker crane for automated storage and retrieval systems (AS / RS). Background Technology

[0002] A warehouse stacker crane is a specialized piece of equipment used for stacking goods in warehouses. It automates the storage, retrieval, and handling of goods. Warehouse stacker cranes can significantly improve warehouse efficiency and logistics accuracy, while reducing human error and labor costs.

[0003] Chinese Patent CN114524389B discloses a stacker crane for an automated storage and retrieval system (AS / RS), comprising a movable frame, a loading component slidably disposed inside the movable frame, and a telescopic mechanism for supporting goods disposed at the top of the loading component. The telescopic forks are retracted by a power mechanism, and at this time the telescopic forks are still in an inclined state, which helps to maintain the stability of the goods during transportation and prevents them from detaching from the telescopic forks. When the forks are retracted, the goods have already slid to a position near the middle of the telescopic forks, so the pressure applied to the forks has been greatly reduced, thereby avoiding the application of excessive torque to the forks and causing damage.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the telescopic mechanism and the load-bearing components make it possible for the mobile frame to move only one set of goods at a time, which increases the travel distance of the mobile frame and reduces work efficiency. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a stacker crane for automated storage and retrieval systems (AS / RS).

[0006] The technical solution of this utility model is as follows: A stacker crane for an automated storage and retrieval warehouse includes a mobile frame with a storage section and a retrieval section; a storage mechanism consisting of multiple sets of storage mechanisms evenly installed in the storage section, each storage mechanism comprising a storage platform mounted on the mobile frame, two sets of connecting boxes symmetrically mounted at the bottom of the storage platform, and multiple sets of rotating rollers rotatably connecting the storage platform and the connecting boxes; two sets of clearance openings symmetrically provided on the storage platform, each clearance opening corresponding to a different set of rotating rollers; and multiple sets of rotating rollers located on both sides of the storage platform, each driven to rotate by a first drive assembly mounted on a corresponding connecting box; a lifting platform, which is adjusted along the height direction of the mobile frame by a lifting mechanism mounted on the mobile frame; and a retrieval mechanism, the bottom of which is equipped with a rotating shaft, which is driven to rotate by a second drive assembly mounted on the lifting platform.

The connecting plate is provided with a plug rod, wherein the ends of the two sets of rotating rollers are equipped with connecting rods, and the other end of the connecting rod extends to the outside of the protective box and has a slot. The connecting rod is rotatably connected to the protective box, and the plug rod abuts against the slot on the connecting rod.

[0009] Preferably, the top of the storage platform is equipped with a C-shaped protective baffle, and the lifting platform is equipped with an L-shaped protective baffle.

[0010] Preferably, the retrieval mechanism includes a rotating platform mounted on the top of a rotating shaft; a first telescopic component disposed on the top of the rotating platform, with an extension seat provided on the first telescopic component; and a second telescopic component disposed on the top of the extension seat, with a retrieval seat provided on the second telescopic component.

[0018] Example 1

[0019] like Figure 1 and Figure 2 As shown, this utility model proposes a stacker crane for an automated storage and retrieval system (AS / RS), comprising a mobile frame 1, a storage mechanism, a lifting platform 3, and a retrieval mechanism. The mobile frame 1 is provided with a storage section and a retrieval section. Multiple storage mechanisms are provided, evenly installed in the storage section. Each storage mechanism consists of a storage platform 2 mounted on the mobile frame 1, two sets of connecting boxes 202 symmetrically mounted at the bottom of the storage platform 2, and multiple sets of rotating rollers rotatably connecting the storage platform 2 and the connecting boxes 202. Two sets of clearance openings 201 are symmetrically provided on the storage platform 2, each corresponding to a set of rotating rollers. The multiple sets of rotating rollers located on both sides of the storage platform 2 are driven by a first drive assembly mounted on the corresponding connecting box 202. The first drive assembly is a motor-driven chain transmission component; the lifting platform 3 is driven by the lifting mechanism 301 set on the moving frame 1 to adjust along the height direction of the moving frame 1, and the lifting mechanism 301 is an electric hoist; the bottom end of the lifting mechanism is equipped with a rotating shaft 302, which is driven to rotate by the second drive assembly installed on the lifting platform 3. The second drive assembly consists of two sets of meshing gears and a motor that is driven to one set of gears. The motor is installed on the lifting platform 3, and the other set of gears is installed on the rotating shaft 302. A reducer is provided at the output end of the motor. The lifting platform 3 is also equipped with a locking component corresponding to the rotating shaft 302. The locking component is driven by an electric push rod and abuts against the side wall of the rotating shaft 302.

[0020] Furthermore, the rotating roller includes a roller 203, which is provided with multiple sets. Rotating rods 204 are installed at both ends of the roller 203. The multiple sets of rotating rods 204 located at one end of the multiple sets of rollers 203 are rotatably connected to one side wall of the connecting box 202. The multiple sets of rotating rods 204 located at the other end of the roller 203 are driven to rotate by a first driving assembly installed on the outer wall of the connecting box 202.

[0021] Furthermore, a connecting plate 206 is mounted on the protective shell of the first drive assembly via a hydraulic rod. The connecting plate 206 has an insert rod 207, with connecting rods 205 mounted at the ends of the two sets of rotating rollers. The other end of the connecting rod 205 extends to the outside of the protective box and has a slot. The connecting rod 205 rotatably connects to the protective box, and the insert rod 207 abuts against the slot on the connecting rod 205. When the first drive assembly drives multiple sets of rotating rollers to move the goods to a suitable position in the storage platform 2, the controller activates the hydraulic rod to move the connecting plate 206 toward the connecting rod 205 until the insert rod 207 abuts against the slot in the connecting rod 205, thereby limiting the rotation of the multiple sets of rotating rollers and preventing the goods from easily falling off.

[0022] Furthermore, the top of the storage platform 2 is equipped with a C-shaped protective baffle, and the lifting platform 3 is equipped with an L-shaped protective baffle to avoid interfering with the delivery mechanism of the goods and to protect the goods.

[0023] In this embodiment, during actual use, the bottom of the mobile frame 1 is installed on the horizontal moving mechanism. The controller starts the horizontal moving mechanism to move the mobile frame 1 to a suitable position. The lifting mechanism 301 starts the lifting mechanism to move the retrieval mechanism along the mobile frame 1 to a suitable height to retrieve the goods on the shelf. When the goods reach the top of the retrieval mechanism, the controller starts the second drive component to drive the rotating shaft 302 to rotate 90 degrees. Then, the retrieval mechanism is adjusted to push the goods onto the storage platform 2, so that the bottom sides of the goods are respectively located on multiple sets of rotating rollers on both sides of the storage platform 2. At the same time, the first drive component drives the multiple sets of rotating rollers to rotate, smoothly conveying the goods to the storage platform 2. Then, the controller rotates the retrieval mechanism 90 degrees back to the initial position and adjusts it to the next suitable height to retrieve the next set of goods. Finally, the goods are transported to the storage platform 2 on other layers, so that multiple sets of goods can be retrieved at one time. When the mobile frame 1 moves to the unloading point, the reverse rotation of the multiple sets of rotating rollers can move the goods to the top of the retrieval mechanism. The retrieval mechanism can then unload the goods one by one, reducing the travel distance of the mobile frame 1 and improving work efficiency.

[0024] Example 2

[0025] like Figure 1 , Figure 3 and Figure 4As shown, the stacker crane for automated storage and retrieval systems proposed in this utility model, compared with Embodiment 1, includes a retrieval mechanism comprising a rotating platform 4, a first telescopic component, and a second telescopic component; the rotating platform 4 is mounted on the top of the rotating shaft 302; the first telescopic component is disposed on the top of the rotating platform 4, and an extension seat 6 is provided on the first telescopic component; the second telescopic component is disposed on the top of the extension seat 6, and a retrieval seat 7 is provided on the second telescopic component. The first telescopic component and the second telescopic component have the same structure. The second telescopic component consists of two sets of mounting seats 5, a threaded rod 501 that is rotatably connected to the mounting seat 5 by a motor mounted on the mounting seat 5, and a moving block 502 that is threadedly sleeved on the outside of the threaded rod 501. The moving block 502 is slidably connected to the inner wall of the mounting seat 5, and the top of the moving block 502 is connected to the extension seat 6 or the retrieval seat 7.

[0026] Furthermore, the side wall of the mounting base 5 is provided with a sliding groove 503, and L-shaped sliders are symmetrically provided at one bottom end of the extension base 6 and the retrieval base 7. The L-shaped sliders are slidably connected to the corresponding sliding grooves 503. The other end of the extension base 6 and the retrieval base 7 is provided with an L-shaped sliding rod 504. The other end of the L-shaped sliding rod 504 is slidably connected to the inner cavity of the side wall of the rotating table 4 or the extension base 6, which improves the connection stability between the extension base 6 and the rotating table 4 and between the retrieval base 7 and the extension base 6, and avoids the retrieval base 7 from being unsupported and subjected to large forces when retrieving goods.

[0027] In this embodiment, when the lifting platform 3 and the lifting mechanism 301 drive the retrieval mechanism to a suitable height, the controller starts the motor to drive the threaded rod 501 to rotate, thereby driving the moving block 502 to slide along the inner wall of the mounting base 5, driving the L-shaped slider to slide along the slide groove 503, and driving the L-shaped slide rod 504 to slide along the corresponding slide cavity. Then, the extension seat 6 and the retrieval seat 7 are unfolded one by one in the direction away from the rotating platform 4. After the retrieval seat 7 is brought close to the bottom fork plate of the goods on the shelf, the lifting mechanism 301 drives the lifting platform 3 to move upward, so that the fork plate of the goods is pressed against the retrieval seat 7. Then, the motor drives the threaded rod 501 to rotate in the opposite direction, so that the retrieval seat 7 and the goods are brought back to the top of the lifting platform 3. At this time, the retrieval of the goods can be completed.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
