DETAILED DESCRIPTION

[0027] The technical solution of the present invention is further described in detail below through specific implementation methods.

[0028] Example 1 This embodiment provides a filter rod tray storage and retrieval device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, it includes a shelf 3, a pair of material box conveyor lines 4, a pair of elevators and a number of shuttles 2. The shelf 3 is used to store the material box 12 and to support the shuttle 2 to move. A pair of the material box conveyor lines 4 are symmetrically arranged at the lower part of the shelf 3, and are used to convey the material box 12 into the shelf 3 or to send it out from the shelf 3. A pair of the elevators are respectively arranged at both ends of the shelf 3, and are used to drive the shuttle 2 to change layers on the shelf 3. According to the distribution position, the pair of elevators can be divided into a left elevator 1 and a right elevator 7.

[0029] The plurality of shuttle vehicles 2 can be movably arranged on the shelf 3, the material box conveying line 4 and the elevator, and are used to take, store and transport the material box 12. The plurality of shuttle vehicles 2 run in a ring in the shelf 3.

[0030] In order to facilitate picking up and loading goods, the shuttle 2 includes a shuttle body 15 and a fork 13 that is retractable and liftable and is arranged on the shuttle body 15. The fork 13 is connected to the fork telescopic drive assembly 32 and the fork lifting drive assembly. The shuttle body 15 is connected to the travel drive assembly 14. The travel drive assembly includes a travel drive motor and a travel wheel.

[0031] like Figure 5 As shown, the fork telescopic drive assembly includes a fork telescopic drive motor 32, a sprocket shaft 34, a sprocket, a chain 33, and a rack 24 arranged on the bottom of the fork 13. The sprocket is arranged on the sprocket shaft 34, and the sprocket shaft 34 is connected to the fork telescopic drive motor 32. The chain 33 is installed on the sprocket, and the chain 33 drives the rack 24 to move back and forth, thereby driving the fork 13 to telescope.

[0032] Specifically, Figure 7 and Figure 8 As shown, in order to smoothly lift, the fork lift drive assembly includes an upper fork plate 16, a lower fork plate 26, a connecting plate 25, a lifting motor 28, a screw rod 29, a screw nut 27, a plurality of guide posts 17, a plurality of guide rails 23, and a plurality of sliders 20. The lifting motor 28, the screw rod 29, and the guide rails 23 are respectively arranged on the lower fork plate 26. The slider 20 and the screw nut 27 are respectively arranged on the connecting plate 25, and the lifting motor 28 drives the screw rod 29 to rotate and then pulls the connecting plate 25 and the slider 20 to slide along the guide rail 23 through the screw nut 27.

[0033] An inclined groove 30 is provided on the inner side of the slider 20, and the guide column 17 and the roller mounting plate 19 are respectively provided on the bottom surface of the upper fork plate 16. The guide column 17 passes through the lower fork plate 26 and the connecting plate 25 in sequence. The guide column 17 is slidably matched with the lower fork plate 26 and the connecting plate 25 respectively, and the roller mounting plate 19 is provided with a roller that is slidably matched with the inclined groove 30. The roller mounting plate 19 passes through the lower fork plate 26 and the connecting plate 25 in sequence. A clearance hole 21 is provided on the connecting plate 25. When the slider 20 slides along the guide rail 23, the roller is forced to slide along the inclined groove 30, and then the upper fork plate 16 is driven to move up and down along the guide column 17 through the roller mounting plate 19.

[0034] Specifically, in order to provide support at the highest point and the lowest point, the two ends of the inclined groove 30 are connected with horizontal grooves to form a Z-shaped groove. In this embodiment, two connecting plates are slidably arranged on the lower plate of the fork, and two pairs of sliders are arranged on each connecting plate, and each pair of sliders are connected by a synchronous connecting rod 22.

[0035] Example 2 The present embodiment provides a filter rod tray storage and retrieval device, and the main difference from Embodiment 1 is that in the present embodiment: in order to facilitate the movement of the shuttle vehicle on shelves of different heights, the shelves include storage spaces for storing multiple layers of supply boxes, and each layer of the shelves 3 is respectively provided with a running track 8 for the movement of the shuttle vehicle 2, and both ends of the running track 8 are respectively connected to a pair of the elevators, so that the shuttle vehicle 2 can move between the running track 8 and the elevator.

[0036] Example 3 This embodiment provides a filter rod tray storage and retrieval device, which is mainly different from the embodiment 1 in that, in this embodiment: in order to improve structural stability and operational safety, a fork support track 31 is further provided on the shuttle body 15, and the fork support track 31 is used to support the bottom of the fork 13 when the fork is extended outward. In order to improve the support stability, a plurality of fork support wheels 18 rollingly matched with the fork support track 31 are provided on the lower surface of the connecting plate 25.

[0037] Example 4 This embodiment provides a filter rod tray storage and retrieval device, which is mainly different from Embodiment 1 in that, in this embodiment: in order to improve the efficiency of loading and unloading, each of the material box conveying lines includes an upper loading layer 5 and a lower unloading layer 6. In order to avoid congestion, the lifting states of the shuttle vehicles carried by a pair of elevators are different.

[0038] Specifically, the material box storage process of the filter rod tray storage and retrieval device provided by the present invention is as follows: The material box 12 is transported to the material box pick-up and placement position of the incoming layer 5 in the shelf through the material box conveyor line 4. When the shuttle 2 receives the order to pick up the goods, the travel drive assembly 14 drives the shuttle 2 along the travel track 8 on the shelf 3 to reach the pick-up point, and then the fork telescopic drive assembly 32 on it starts to run and drives the fork 13 to extend. When the fork 13 is extended, the fork support wheel 18 travels along the fork support track 31, which plays a role in preventing the fork 13 from sagging. Specifically, the fork telescopic drive assembly 32 includes a telescopic drive motor, a sprocket, a chain 33, a sprocket shaft 34, and a rack 24 driven by the chain 33.

[0039] When the fork 13 is completely moved to the bottom of the material box 12, the lifting motor 28 installed on the lower plate 26 of the fork starts to rotate, and the synchronous pulley on it starts to rotate. Through the synchronous belt, the active synchronous pulley drives the driven synchronous pulley to rotate. The driven synchronous pulley is installed on the screw rod 29, driving the screw rod 29 to rotate, thereby driving the screw nut 27 on the screw rod to move forward and backward. The screw nut 27 is fixed on the connecting plate 25, and the slider 20 is also fixed on the connecting plate 25, so that the slider 20 starts to move forward and backward. The slider 20 is provided with an inclined groove 30 for the roller to roll. The shape of the inclined groove 30 is a linear groove with a drop in the height direction. When the slider 20 moves forward and backward, the roller moves along the inclined groove 30, one end of the roller is fixed to the upper plate 16 of the fork through the roller mounting plate 19, and the other end is in the inclined groove 30 of the slider, thereby driving the upper plate 16 of the fork to rise, and the material box 12 rises and leaves the shelf 3.

[0040] Then the fork telescopic drive assembly 32 starts to operate, driving the fork 13 to retract. When the fork 13 is fully retracted into the shuttle 2, the fork telescopic drive assembly 32 stops operating, and then the lifting motor 28 reverses, and the active synchronous pulley on it starts to reverse, and through the synchronous belt, the active synchronous pulley drives the driven synchronous pulley to reverse, and the driven synchronous pulley drives the screw 29 to reverse, thereby driving the screw nut 27 on the screw 29 to move in the reverse direction, so that the slider 20 starts to move in the reverse direction.

[0041] When the slider 20 moves forward and backward, the roller on the upper plate 16 of the fork moves along the groove, thereby driving the upper plate 16 of the fork to descend, and the cargo is picked up. Then the shuttle 2 runs along the running track 8 to the left end of the left elevator 1 car, the elevator rises to the target floor, and the shuttle 2 drives out of the left elevator 1 to the target cargo position. Then the lifting motor 28 installed on the lower plate 26 of the fork starts to rotate, and the active synchronous pulley on it starts to rotate. Through the synchronous belt, the active synchronous pulley drives the driven synchronous pulley to rotate. The driven synchronous pulley is installed on the screw 29, driving the screw 29 to rotate, thereby driving the screw nut 27 on the screw 29 to move forward and backward.

[0042] The screw nut 27 is fixed on the connecting plate 25, and the slider 20 is also fixed on the connecting plate 25, so that the slider 20 starts to move forward and backward. When the slider 20 moves forward and backward, the roller starts to move along the groove on the slider, one end of the roller is fixed to the upper fork plate 16 through the roller mounting plate, and the other end is in the groove of the slider, thereby driving the upper fork plate 16 to rise and lift the material box to the target height.

[0043] Then the fork telescopic drive assembly 32 drives the fork 13 to extend, and after reaching the specified position, the fork 13 descends to place the material box on the shelf 3, and then the fork telescopic drive assembly 32 drives the fork 13 to retract to the vehicle body. Then the shuttle 2 runs to the right hoist 7 according to the control system instruction, and the right hoist 7 descends to the cargo picking layer, and the shuttle 2 drives out to perform the next task. Among them, the left hoist and the right hoist both include a hoist frame 10, a hoist car 11 and a hoist counterweight 9.

[0044] Similarly, the process of picking up materials from the container is as follows: The shuttle 2 receives the order to pick up goods from the control system, and then the shuttle 2 runs along the travel track 8 to the cabin of the left elevator 1. The elevator rises to the target floor number, and the travel drive assembly 14 drives the shuttle 2 along the travel track on the shelf to reach the target point. Then the fork telescopic drive assembly 32 on it starts to run, driving the fork 13 to extend. When the fork 13 is extended, the fork support wheel 18 runs along the fork support track 31, which plays a role in preventing the fork 13 from sagging. When the fork 13 completely runs to the bottom of the material box, the lifting motor 28 installed on the lower plate 26 of the fork starts to rotate, and the synchronous pulley on it starts to rotate. Through the synchronous belt, the active synchronous pulley drives the driven synchronous pulley to rotate. The driven synchronous pulley is installed on the screw rod 29, driving the screw rod 29 to rotate, thereby driving the screw nut 27 on the screw rod 29 to move back and forth.

[0045] The lead screw nut 27 is fixed on the connecting plate 25, and the slider 20 is also fixed on the connecting plate 25, so that the slider 20 starts to move forward and backward. The slider 20 is provided with a groove for the roller to roll, and the shape of the groove is a linear inclined groove 30 with a drop in the height direction. When the slider moves forward and backward, the roller moves along the groove, one end of the roller is fixed to the upper plate of the fork through the roller mounting plate, and the other end is in the groove of the slider, thereby driving the upper plate of the fork to rise, the material box to rise, and leave the shelf. Then the fork telescopic drive assembly runs, driving the fork to retract. When the fork is fully retracted into the shuttle, the fork telescopic drive assembly stops running, and then the lifting motor reverses, and the active synchronous pulley on it starts to reverse. Through the synchronous belt, the active synchronous pulley drives the driven synchronous pulley to reverse, and the driven synchronous pulley drives the lead screw to reverse, thereby driving the lead screw nut on the lead screw to move in the opposite direction, so that the slider starts to move in the opposite direction.

[0046] When the slider moves forward and backward, the roller on the upper plate 16 of the fork moves along the inclined slot 30, thereby driving the upper plate of the fork to descend, and the picking of goods is completed. Then it runs to the right elevator 7, and the right elevator 7 descends to the first delivery layer. The shuttle 2 runs to the delivery point of the first delivery layer. The shuttle 2 drives the fork to rise to the target height through the fork lifting component, and then the fork telescopic component drives the fork to extend. After it is in place, the fork descends to its original position, and the material box is placed on the material box conveyor line 4. Then the fork retracts to the shuttle, and the goods are released. The shuttle starts to perform the next task.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
