Description

Technical Field

[0001] The present invention relates to the technical field of stackers, in particular to a double-column aisle stacker for an automated stereoscopic warehouse. Background Art

[0002] The double-column aisle stacker is a type of storage equipment used in automated high-bay warehouses. It mainly operates in the aisles of the warehouse and performs storage and retrieval operations on goods between shelves. Its structural feature is that it has two columns, which serve as the main supporting structure. Between the columns are installed components such as a cargo platform and forks, which can move vertically and horizontally along the aisle. The existing double-column aisle stacker has the following disadvantages when in use: 1. The fork is one of the components of the stacker, which can be specifically divided into a telescopic fork and a clamping fork. When in use, the telescopic fork needs to be transferred to the bottom of the goods through the vertical operating mechanism first, and then the fork is extended to the bottom of the goods. The vertical operating mechanism then drives the fork up to make the goods leave the shelf, and then the fork retracts to move the goods out of the shelf. Similarly, when releasing the goods, the vertical operating mechanism needs to drive the fork down. Since the lifting and lowering actions required for the fork to support the goods must be performed by the vertical operating mechanism, not 1. It cannot be realized independently, which makes the control of the vertical operation mechanism complicated, and also reduces the service life of the vertical operation mechanism and increases the risk of failure; 2. The telescopic fork generally adopts a three-stage design, with the lower fork and the middle fork driven by a gear rack, and the middle fork and the upper fork driven by a chain or belt. This transmission mechanism is relatively complicated, resulting in high production costs and increasing the difficulty of subsequent maintenance; 3. The existing double-column aisle stacker lacks a temporary storage structure for goods, so it is necessary to constantly go back and forth in the aisle to pick up goods, which leads to relatively low work efficiency.

[0025] Working principle: When using the present invention, the mobile seat 1 is used to drive the double-column lift 11 to make linear motion in the lane, the double-column lift 11 is used to drive the rotating platform 12 to lift and lower, and the rotating platform 12 is used to drive the fork assembly 2 to rotate. At the loading point, the fork assembly 2 can be used to transfer all the goods to be stored to the temporary storage rack 15 of the shelf 14. When storing goods later, it is only necessary to take the goods out of the temporary storage rack 15, or to put the taken-out goods on the temporary storage rack 15 and then transfer them to the unloading position for unloading. The specific method of using the fork assembly 2 is as follows: when taking goods, the motor 22 The first pulley 24 is driven by the first rotating shaft 23, and the first pulley 24 is combined with the second pulley 26 to realize the forward transmission of the transmission belt 25. The second connecting block 28 on the transmission belt 25 moves accordingly, thereby driving the upper fork 212 to extend. Since the first connecting block 27 is fixed to the lower fork 29, the first connecting block 27 cannot move, causing the middle fork 21 to move and extend relative to the lower fork 29. When the upper fork 212 reaches the bottom of the cargo, the upper fork 212 continues to extend, and the first stop 223 is blocked by the third stop 231, so that the first stop 223 drives the slider 219 to slide in the slide groove 218, and the slider 219 The upper fork 212 moves in the opposite direction, and the second stop block 225 compresses the second spring 226. At the same time, the ratchet plate 221 drives the ratchet 228 to rotate 180 degrees, and the second rotating shaft 227 on the ratchet 228 rotates 180 degrees accordingly. The mounting bracket 229 on the second rotating shaft 227 also rotates accordingly, and the third roller 230 on the mounting bracket 229 lifts the top block 217, so that the top plate 215 on the top block 217 is lifted. The top plate 215 moves up along the guide hole 214 through the guide rod 216 to lift the goods. Then the motor 22 reverses, driving the upper fork 212 and the middle fork 21 to retract and return to their original position, and the goods are transferred to the rotating platform. The area of ​​the platform 12, and at the same time, under the elastic force of the second spring 226 in the receiving groove 224, the slider 219 automatically resets, and the rotating platform 12 rotates a certain angle, so that the fork assembly 2 is aligned with the cargo storage position, and the motor 22 rotates forward, driving the upper fork 212 and the middle fork 21 to extend again. At the same time, after reaching the cargo storage position, the ratchet plate 221 will again drive the ratchet wheel 228 to rotate 180 degrees, so that the top plate 215 loses the support of the third roller 230. Under the action of gravity, the cargo will fall into the storage position, and then the motor 22 reverses, causing the upper fork 212 and the middle fork 21 to retract and return to their original position, completing the storage of the cargo;A certain amount of friction exists between the second rotating shaft 227 and the upper fork 212, preventing the ratchet plate 221 from driving the ratchet wheel 228 during the return of the slider 219. The limiting groove 220 is used to limit the ratchet plate 221, and the first spring 222 is used to provide a return force for the ratchet plate 221. The connecting plate 210 cooperates with the first roller 211 to achieve a sliding connection between the middle fork 21 and the lower fork 29. The second roller 213 is used to achieve a sliding connection between the middle fork 21 and the upper fork 212. The connecting frame 13 is used to connect the dual-post lift 11 and the two shelves 14. The movable base 1, dual-post lift 11, and rotating platform 12 are all implemented using existing technologies and will not be described in detail.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
