Description

Technical Field

[0001] This utility model relates to the field of stopping technology for automated warehouse shuttle cars, and in particular to a stopping linkage device. Background Technology

[0002] With the rapid development of modern logistics, automated storage and retrieval systems (AS / RS), as a core component of automated warehousing systems, are increasingly valued for their efficient and precise cargo storage and retrieval capabilities. In AS / RS systems, shuttles and elevators are key equipment for achieving automated cargo handling. Shuttles move horizontally along tracks to store and retrieve goods, while elevators transfer goods vertically between different storage levels. Because AS / RS operations require frequent starts and stops and operate at high speeds, high requirements are placed on the safety protection of the equipment.

[0003] In existing technologies, to ensure the safe operation of shuttle vehicles, mechanical or electronic stop devices are typically installed at the end of the tracks on each level of the automated warehouse to prevent the shuttle vehicle from derailing due to unexpected situations. Simultaneously, an independent stop mechanism is also installed on the hoist platform to prevent the shuttle vehicle from shifting or even falling during hoisting. While this safety design provides a certain degree of protection, it involves two completely independent stop systems: one is a stop device fixed to the end of the warehouse tracks, and the other is a stop mechanism installed on the hoist platform. These two systems require separate control, which not only increases the complexity of the control system but also occupies valuable track and hoist platform space. Furthermore, because the two stop mechanisms need to coordinate their actions, asynchronous control timing can easily occur, increasing the risk of system failure. Utility Model Content

[0056] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0057] like Figure 1 , Figure 6 , Figure 7As shown, the stop linkage device provided in this embodiment is used in an automated warehouse and includes: a first stop mechanism 3, a drive mechanism 4, and a second stop mechanism 5; both the first stop mechanism 3 and the drive mechanism 4 are installed on the hoist 2; the second stop mechanism 5 is installed on the automated warehouse guide rail 1; the first stop mechanism 3 has a stop plate 305 that can rotate relative to the hoist 2, and the second stop mechanism 5 has a blocking block 501 that can rotate relative to the automated warehouse guide rail 1; the drive mechanism 4 is connected to the stop plate 305 and the blocking block 501 respectively to drive the stop plate 305 to rotate and the blocking block 501 to rotate, so as to switch between a vertical blocking state and a horizontal passage state.

[0058] It should be noted that the first stop mechanism 3, the drive mechanism 4, and the second stop mechanism 5 are on the same horizontal plane and are all installed below the plane of the vertical warehouse guide rail 1.

[0059] The stop linkage device provided in this embodiment is applied to the area between the hoist 2 and the vertical warehouse guide rail 1 in the automated warehouse system. Through the mechanical transmission connection between the drive mechanism 4 and the stop plate 305 and the blocking block 501, the linkage action of the two stop mechanisms can switch between the vertical blocking state and the horizontal passage state without relying on an independent electrical control circuit or sensor feedback mechanism. This improves the response speed and reliability of the stop switching action and reduces the risk of malfunction due to electrical control delay or failure.

[0060] Regarding the structure and shape of the first stop mechanism 3, specifically:

[0061] like Figure 2 As shown, the first stop mechanism 3 includes a bracket 301, a first base 302, a rotating member 304, and a stop plate 305. The bracket 301 is used to connect with the hoist 2. The first base 302 is fixed on the bracket 301. The rotating member 304 is rotatably mounted on the first base 302 and connected to the stop plate 305. The drive mechanism 4 is connected to the rotating member 304 to drive the rotating member 304 to rotate around its own axis, thereby causing the stop plate 305 to switch between a vertical blocking position and a horizontal passing position.

[0062] In an optional embodiment, the first base 302 is provided with a notch or groove that forms a rotational space to accommodate the stop plate 305. This structural design allows the stop plate 305 to be completely retracted into the rotational space when lying flat, avoiding interference with the operation of the hoist 2, and improving space utilization and structural compactness.

[0063] The first stop mechanism 3 also includes a first sliding sleeve 303, which is disposed on the first base 302 and is used to guide the movement trajectory of the push rod 409 and enhance transmission stability.

[0064] Regarding the structure and shape of the second stop mechanism 5, specifically:

[0065] like Figure 4 , Figure 8 , Figure 9 As shown, the second stop mechanism 5 includes a mounting frame 504, a pusher 502, a blocking block 501, and an elastic member 505. The mounting frame 504 is fixed on the vertical guide rail 1. The pusher 502 is specifically configured as a rod-shaped structure. The pusher 502 passes through the mounting frame 504 and is connected to the blocking block 501 through a gear and rack structure. This allows the pusher 502 to drive the blocking block 501 to rotate during horizontal movement. When the pusher 502 moves, it drives the blocking block 501 to rotate through the gear and rack transmission, thereby realizing the switching of the blocking block 501 between the vertical blocking position and the horizontal passing position.

[0066] An elastic element 505 is provided between the pusher 502 and the mounting bracket 504. The elastic element 505 is specifically configured as a compression spring. One end of the elastic element 505 is fixed to the mounting bracket 504, and the other end is connected to the pusher 502, so that the pusher 502 has a tendency to move towards the drive mechanism 4 in its natural state. Thus, when not acted upon by the drive mechanism 4, the blocking block 501 is automatically in a vertical blocking position, realizing the automatic reset function.

[0067] Additionally, it should be noted that in its natural state, the elastic element 505 has a certain gap between the pusher 502 and the push plate 402.

[0068] In a preferred embodiment, the second stop mechanism 5 further includes a third detection component 503, which is specifically configured as a photoelectric switch and is installed on the hoist 2. It is used to detect whether the blocking block 501 has been completely switched to the lying pass position or the vertical blocking position, thereby providing status feedback for subsequent control.

[0069] The vertical storage guide rail 1 is provided with a through hole 11, which allows the blocking block 501 to partially extend out of the guide rail when it is in the vertical blocking position, so as to realize the blocking function; when it is in the horizontal passing state, the blocking block 501 can be completely retracted into the guide rail to avoid obstructing the passage of the hoist 2.

[0070] Regarding the structure and shape of the drive mechanism 4, specifically:

[0071] like Figure 3 , Figure 5 As shown, the drive mechanism 4 includes a drive component 401, a push plate 402, a second base 403, a push rod 409, a second sliding sleeve 405, a baffle 406, a first detection component 407, a second detection component 408, and a connecting frame 404.

[0072] The driving component 401 is specifically configured as a drive motor, fixed on the second base 403, which is mounted on the hoist 2. A push plate 402 is connected to the end of the drive rod of the driving component 401. The push plate 402 pushes the pusher 502, thereby causing the blocking block 501 in the second stop mechanism 5 to switch positions. The push rod 409 is engaged with the rotating component 304. Under the action of the driving component 401, the drive rod drives the push rod 409 to move, which in turn drives the rotating component 304 to rotate, thus achieving the switching of the stop plate 305 in the first stop mechanism 3.

[0073] like Figure 5 As shown, the push rod 409 has a rack segment, and the outer surface of the rotating part 304 also has a rack, thereby realizing the meshing connection between the push rod 409 and the rotating part 304.

[0074] The push rod 409 passes sequentially through the first sliding sleeve 303 set on the first base 302 and the second sliding sleeve 405 set on the second base 403 to ensure the guiding accuracy and structural stability during its movement.

[0075] Furthermore, the baffle 406 is fixed to the push rod 409, the connecting frame 404 is connected to the second base 403, and the first detection component 407 and the second detection component 408 are disposed on the connecting frame 404. Both the first detection component 407 and the second detection component 408 are configured as proximity switches and maintain a certain distance from each other in the axial direction of the push rod 409. By detecting whether the baffle 406 passes the first detection component 407 or the second detection component 408, the movement position of the push rod 409 can be determined, and thus it can be determined whether the stop plate 305 and the blocking block 501 have been switched into position.

[0076] It should be noted that in its natural state, there is a certain gap between the push plate 402 and the pusher 502 to avoid interference and collision between the elevator 2 and the pusher 502 when the elevator is raised or lowered.

[0077] The linkage control principle is as follows: After the drive component 401 is activated, the drive rod drives the push plate 402 to push the pusher 502 forward. The pusher 502 drives the blocking block 501 to rotate through the gear and rack structure, thereby switching the second stop mechanism 5. At the same time, the push rod 409 meshes with the rotating component 304, driving the stop plate 305 to rotate, thereby switching the first stop mechanism 3. The two stop structures switch synchronously under the unified action of the drive mechanism 4, thus achieving linkage control.

[0078] The working principle of the stop linkage device provided in this embodiment is as follows:

[0079] In the initial stop state, the stop plate 305 of the first stop mechanism 3 and the blocking block 501 of the second stop mechanism 5 are both in the vertical stop state and do not interfere with each other. The first detection component 407 detects that the baffle 406 is energized, and the hoist 2 can move freely up and down. When the hoist 2 receives information from the host system that the shuttle on a certain cargo floor needs to change floors, the hoist 2 moves to the vertical warehouse guide rail 1 where the shuttle is located. After stopping, the third detection component 503 detects the light signal reflected back from the blocking block 501. At this time, it is confirmed that the hoist 2 has accurately reached the position. The start drive component 401 drives the push plate 402 to move forward. After a period of idle travel, the push component 502 is pushed to retract into the mounting frame 504. The push component 502 drives the blocking block 501 to rotate and lie flat. At the same time, the push rod 409 drives the baffle 406 to move synchronously and drives the rotating component 304 and the stop plate 305 to rotate and lie flat. At this time, the second detection component 408 detects that the baffle 406 is energized and stops driving component 401. The photoelectric switch fails to detect the reflected light signal and is de-energized. The stop linkage mechanism is in the pass state, and the shuttle car can slowly move from the vertical warehouse guide rail 1 to the hoist 2.

[0080] After the shuttle car moves to the designated position on the hoist 2, the drive component 401 drives the push plate 402 to retract. The pusher 502, under the action of the internal compression spring elastic element 505, slowly extends and drives the blocking block 501 to rotate and stand upright. Simultaneously, the push rod 409 drives the baffle 406 to move synchronously, causing the rotating component 304 and the stop plate 305 to rotate and stand upright. At this time, the first detection component 407 detects that the baffle 406 is energized and stops the drive component 401. The third detection component 503 detects the light signal reflected back from the blocking block 501 and is energized. At this point, the stop linkage device returns to the initial stop state, and the hoist 2 carrying the shuttle car can then be raised and lowered to the designated cargo level of the main system.

[0081] Similarly, after the hoist 2 carrying the shuttle car reaches the designated cargo floor, the stop linkage device still needs to change from the initial stop state to the pass state before the shuttle car can move from the hoist 2 onto the vertical storage guide rail 1. When the shuttle car reaches the designated position on the vertical storage guide rail 1, the stop linkage device changes from the pass state back to the initial stop state. At this time, the hoist 2 can execute other floor-changing commands issued by the main system.

[0082] The technical advantages of the stop linkage device provided in this embodiment are as follows:

[0083] 1. Compact structure: The layout of each component is reasonable, saving space and facilitating integrated installation between the hoist 2 and the vertical storage guide rail 1.

[0084] 2. Reliable operation: The mechanical linkage method avoids the risks of delay and malfunction in traditional electrical control.

[0085] 3. Fast response speed: The drive mechanism 4 acts directly on the stop plate 305 and the blocking block 501 without waiting for sensor feedback or program control.

[0086] 4. Automatic reset function: The elastic element 505 is designed to ensure that the blocking block 501 can automatically return to the vertical blocking state after the drive mechanism 4 stops working.

[0087] 5. Status detection function: The status of the stop mechanism can be detected in real time through the detection component, providing feedback support for subsequent control.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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 therein. Such 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 this utility model.
