Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent vertical warehouse automatic storage and retrieval, and particularly relates to an intelligent vertical warehouse storage and retrieval system. BACKGROUND

[0002] The intelligent vertical warehouse is also called intelligent vertical storage, which is a highly rationalized, automatic storage and retrieval and simple operation by using the cooperation of automatic storage equipment and computer management system.

[0003] The patent application file with the patent publication number CN104787534A discloses a jacking type automatic long rod material storage and retrieval method and device, which is mainly used for storing long rod materials. However, the device has the following technical defects: 1. The lifting vehicle of the device uses four lifting chains to form a lifting system for upward and downward movement, but such a lifting system is prone to shaking. This results in that the lifting vehicle is not safe when lifting and transporting materials, and the accuracy is not high; 2. The lifting vehicle of the device uses the supporting stand plate on the tray and the hopper to contact and lift the materials, so a hopper is needed on the vertical warehouse. Since the number of storage locations of the vertical warehouse is large, a hopper is needed for each storage location. Therefore, the vertical warehouse needs to additionally bear the weight of multiple vertical warehouses. At the same time, since the two ends of the hopper supported by the tray are in a suspended state, the supporting stand plate on the hopper bears a very large weight. Therefore, if the weight of the materials in the hopper is relatively heavy, the connection between the supporting stand plate and the hopper needs to be very firm; 3. When taking materials, the lifting vehicle uses a horizontal movement system to move the tray to the lower side of the supporting stand plate, and then the lifting vehicle supports the hopper. However, after the tray is horizontally moved to the lower side of the hopper, the center of gravity of the lifting vehicle will be offset when the hopper is lifted, which may cause the lifting vehicle to tilt and pose a safety hazard; 4. The device can only be used for the storage and retrieval of long rod materials. If the materials are short, there will be a row of storage locations arranged on both sides of the aisle. At this time, the device is difficult to store and retrieve materials from the row of storage locations. SUMMARY

[0034] The present invention is further described in detail below through specific examples.

[0035] Example 1

[0036] like Figures 1 to 4 As shown, a storage and retrieval system for an intelligent vertical warehouse 1 includes a frame, a ceiling rail 9 disposed above the intelligent vertical warehouse 1, and a movable overhead crane 2 mounted on the ceiling rail 9 for horizontal sliding movement in the X direction. In this embodiment, the frame can be independent of the intelligent vertical warehouse 1, with the entire intelligent vertical warehouse 1 positioned below the frame. Alternatively, the entire intelligent vertical warehouse 1 can serve as the supporting frame, with the ceiling rail 9 mounted on the top frame of the intelligent vertical warehouse 1.

[0037] A storage and retrieval platform 3 that can be raised and lowered along the Z direction is installed below the overhead crane 2 through a suspension and pulling mechanism. The storage and retrieval platform 3 is driven by a lifting power device installed on the overhead crane 2 to rise and fall between the upper limit position and the lower limit position.

[0038] The overhead crane 2 in this embodiment includes an overhead crane frame 21, which is provided with a platform window 23 for accommodating the storage and retrieval platform 3. The frame is provided with an overhead rail extending in the X direction. The overhead crane frame 21 is provided with a traveling mechanism 22 that travels along the overhead rail extending in the X direction. The intelligent vertical warehouse 1 is provided with a plurality of lanes 5 for accommodating the storage and retrieval platforms 3. When the storage and retrieval platform 3 is within the platform window 23 and above the intelligent vertical warehouse 1, it leaves the intelligent vertical warehouse 1 and moves with the overhead crane 2 to any lane 5. The traveling mechanism 22 on the overhead crane 2 is a conventional structure and will not be described in detail here.

[0039] The suspension pulling mechanism is a steel wire pulling mechanism or a chain pulling mechanism. In the embodiment, the steel wire pulling mechanism is preferred, and a winding power device 24 for winding the steel wire is arranged on the crown block frame 21, and the winding power device 24 is a lifting power device. Four hanging rings 36 arranged in a rectangle are arranged on the access platform 3, the hanging rings 36 are connected to the steel wire, and a steel wire guide wheel 25 is arranged on the crown block 2 to facilitate winding and unwinding of the steel wire.

[0040] In the embodiment, the access platform 3 includes a platform body 31 extending along the Y direction, both ends of the platform body 31 are fixed with end plates 32, two suspension points are arranged on each end plate 32, the hanging rings 36 are arranged on the suspension points, the hanging rings 36 are connected to the suspension pulling mechanism, the access mechanism 33 is arranged on the platform body 31, and the centers of gravity of the materials 8 on the storage locations A on both sides of the aisle 5 are located between the two suspension points on the same end plate 32.

[0041] In the embodiment, the access mechanism 33 is a telescopic fork 332, and the telescopic fork 332 is fixed in the middle of the platform body 31. The telescopic fork 332 is a conventional structure in a stacking machine, and is a conventional structure on the market. For example, a telescopic fork with smooth guidance is disclosed in a new type disclosed in a patent publication No. CN222715040U. In the embodiment, the number of storage locations A of the same height on both sides of the same aisle 5 is one, for example, some long pipes or bars or profiles. At this time, the telescopic fork 332 can slide left and right, the telescopic fork 332 is arranged in the middle position, the distance between the supporting arms between the forks is relatively wide, and the material 8 can be stably supported.

[0042] At the same time, the center of gravity of the material 8 on the storage location A is located between the two suspension points on the same end plate 32. In this way, after the telescopic fork 332 is inserted below the material 8, the access platform 3 is lifted to lift the material 8, and since the center of the material 8 is still between the suspension points when the material 8 is lifted, the access platform 3 is more stable when the material 8 is accessed.

[0043] As Figure 3 and Figure 4As shown, at least one end of each lane 5 is provided with an in-store guide column 6 arranged vertically, the access platform 3 is provided with a lifting limiting structure matched with the side wall of the in-store guide column 6, the lifting limiting structure is separated from the in-store guide column 6 when the access platform 3 is at the upper limit position, the trolley 2 is further fixed with an in-trolley guide column 7 vertically corresponding to the upper end of the in-store guide column 6, the lifting limiting structure is matched with the in-trolley guide column 7 when the access platform 3 is at the upper limit position, the access platform 3 is provided with an access mechanism 33 for storing or taking out the material 8 from the storage location A on both sides of the lane 5, and the height detection device is further arranged between the access platform 3 and the trolley 2 for detecting the height of the access platform 3.

[0044] The height detection device in the embodiment detects by using a laser ranging sensor, and the laser ranging sensor body can be arranged on the access platform 3 or the trolley 2, and a reference plate is arranged on the trolley 2 or the access platform 3 correspondingly, so that the height of the access platform 3 is determined by laser ranging.

[0045] In the embodiment, the lifting limiting structure includes at least four side limiting wheels 34 rotatably mounted on the end plate 32 of the access platform 3, the extension direction of the rotation center of the side limiting wheel 34 is the Y direction, the side limiting wheels form a vertical limiting passage through which the in-store guide column 6 and the in-trolley guide column 7 pass, and the limiting wheels are in rolling cooperation with the opposite two side walls of the in-store guide column 6 and the in-trolley guide column 7. In the embodiment, the in-store guide column 6 is arranged at both ends of the lane 5, and therefore, the side limiting wheels 34 are arranged on the end plate 32 at both ends of the access platform 3.

[0046] The lifting limiting structure further includes at least one intermediate limiting wheel 35 rotatably mounted at both ends of the access platform 3, the extension direction of the rotation center of the intermediate limiting wheel 35 is parallel to the X direction, the intermediate limiting wheel 35 is in the vertical limiting passage, and the intermediate limiting wheel 35 is in rolling cooperation with the inner side of the in-store guide column 6 and the in-trolley guide column 7. Therefore, the side limiting wheel 34 and the intermediate limiting wheel 35 are in cooperation with the in-store guide column 6 and the in-trolley guide column 7, so as to ensure that the access platform 3 is stable and smooth in lifting.

[0047] The lower end of the in-trolley guide column 7 is provided with a downward gradually tapering lower guide tapering portion 71, and the upper end of the in-store guide column 6 is provided with an upward gradually tapering upper guide tapering portion 61, and the lower guide tapering portion 71 and the upper guide tapering portion 61 are in mutual correspondence. Of course, in the embodiment, the proximity switch is arranged on the in-trolley guide column 7, so as to control the uppermost limit position of the access platform 3.

[0048] In this embodiment, the bottom of the intelligent vertical warehouse 1 is provided with a storage and access connection area B, in which an RGV trolley 4 is installed. The RGV trolley 4 connects with the storage and access platform 3 to deliver or bring in materials 8. Figure 2 As shown, the bottom layer of the intelligent vertical warehouse 1 is the access connection area B. Correspondingly, the RGV trolley 4 can move along the track in the access connection area B. The moving direction of the RGV trolley 4 can be set according to the actual layout of the intelligent vertical warehouse 1. For example, it can move along the Y direction or / and the X direction, so that it can enter and exit the warehouse from different positions, which is more adaptable.

[0049] When the RGV trolley 4 is in the process of moving out or in, the storage and retrieval platform 3 can perform other storage and retrieval actions at the same time, so the entire storage and retrieval rhythm is more compact and more efficient.

[0050] Example 2

[0051] like Figure 5 As shown, the structure of this embodiment is basically the same as that of embodiment 1. Figure 5 In the example, the platform body 31 is provided with a Y-guide rail 39 extending in the Y direction. The access mechanism 33 is slidably mounted on the Y-guide rail 39 and driven by a Y-sliding power unit 37. Accordingly, there are at least two storage locations A on the same side of the same aisle 5 at the same height, arranged along the Y direction, allowing for the storage of shorter materials 8. Therefore, the telescopic fork 332 is slidably mounted on the access platform 3 in the Y direction and driven by the Y-sliding power unit 37. This allows the telescopic fork 332 to access storage locations A at different locations at the same height in the same aisle 5.

[0052] In this embodiment, the telescopic fork 332 may be used to store and retrieve the material frame 10 , or the material frame 10 may not be used, for example, the bundled material 8 may be directly stored and retrieved.

[0053] The Y-sliding power device 37 adopts a servo motor and can drive the entire telescopic fork 332 to slide along the Y direction through a traction chain 38.

[0054] Example 3

[0055] like Figures 6 to 8As shown, the structure in the embodiment is basically the same as that of Embodiment 1, except that the access mechanism 33 adopts a push-pull type access mechanism 33, which comprises a base 331, an access slide 333 slidingly mounted on the base 331 in the X direction, and an access power device installed on the base 331 to drive the access slide 333 to slide. In the embodiment, the access power device is a motor, and the base 331 can slide in the X direction through a gear 334 and a rack 335 mechanism. The gear 334 is rotatably installed on the access slide 333 through a transmission shaft, while the rack 335 is fixed on the base 331. A synchronous pulley is also installed on the transmission shaft, and the motor drives the synchronous pulley to rotate through a synchronous belt, thereby driving the gear 334 to rotate and realizing the sliding of the access slide 333.

[0056] The access slide 333 is installed with at least two parallel circulating push-pull chains 336, which are driven to circulate in opposite directions by a push-pull power device 337. Similarly, the push-pull power device 337 is also a motor and is driven by a synchronous belt. The chain shaft 338 of the push-pull chain 336 is fixed with a synchronous pulley, and the synchronous belt between the push-pull chain 336 and the push-pull power device 337 is in transmission. Two push-pull clamping blocks 3361 are arranged at intervals on each push-pull chain 336, and a material frame 10 is placed on the corresponding storage location A. The material frame 10 is provided with an open clamping groove 101 arranged at intervals and matched with the corresponding push-pull clamping block 3361. Figure 8 As shown, when the material frame 10 is located at the storage location A, the access platform 3 is lowered to adapt the push-pull chain 336 to the bottom of the material frame 10 at the storage location A, and then the access power device drives the access slide 333 to move towards the material frame 10. Then the push-pull chain 336 is driven to circulate. At this time, when the push-pull chain 336 circulates, the push-pull clamping block 3361 will move from bottom to top and enter the outermost open clamping groove 101 of the material frame 10. At this time, the push-pull clamping block 3361 will drag the material frame 10 onto the access slide 333. When a certain distance is dragged, the other push-pull clamping block 3361 will again be clamped into another open clamping groove 101 with the same action, so as to completely pull the material frame 10 at the storage location A onto the access slide 333. When storage is needed, the reverse action is adopted.

[0057] Then the access platform 3 is lifted to transfer the material frame 10 to the RGV trolley 4, and then the RGV trolley 4 removes the material frame 10, and the access platform 3 performs the next round of access action.

[0058] Of course, when the RGV trolley 4 is not used for connection, the access platform 3 directly rises to the uppermost limit position at this time. At this time, the access platform 3 is separated from the in-warehouse guide column 6, and then the access platform 3 will move with the overhead crane 2, and when the overhead crane 2 moves to the out-of-warehouse lane 5, the access platform 3 is lowered, and at this time, the material frame 10 can be moved out.

[0059] The intelligent vertical warehouse access in-and-out warehouse system has at least the following advantages compared with the conventional in-and-out warehouse system: 1. The in-and-out warehouse system uses the in-vehicle guide column 7 and the in-warehouse guide column 6 to realize the limiting guide when the access platform 3 is lifted, which ensures the stability of the access platform 3; compared with the existing in-and-out warehouse system, the stability is higher; and the access mechanism 33 in the embodiment is in the middle of the access platform, which directly acts on the bottom of the material for lifting, so that the material frame does not need to be customized, the stress of the lifted material is more reasonable, and the middle part will not be suspended and drooped, so that it is suitable for heavier material access in and out of the warehouse; 2. The suspension point of the access platform 3 is located outside the center of gravity of the material 8 in the warehouse position A, so that the access platform 3 is not easy to tilt when accessing the material 8, and the stability is higher; 3. The access mechanism 33 on the access platform 3 can slide to any position in the Y direction, so that the access of short materials 8 in the same lane and the same layer of multiple warehouse positions can be met.

[0060] The above-described embodiments are only descriptions of preferred embodiments of the present application and are not intended to limit the scope of the present application. Various modifications and improvements to the technical solutions of the present application made without departing from the design spirit of the present application shall fall within the protection scope determined by the claims of the present application.
