[0034] refer to Figure 1 and Figure 2 The embodiment of the utility model provides a filter rod box in-and-out storage system, including a truck 10, a plurality of in-and-out storage conveyors 50, a first lifting and positioning machine 20, a second lifting and positioning machine 40 and a buffer conveying device 30. The truck 10 includes a carriage and a plurality of vehicle-mounted conveyors 11 arranged in the carriage. The carriage has a door located at the rear end, and each vehicle-mounted conveyor 11 is configured to carry and convey filter rod boxes A. A plurality of in-and-out storage conveyors 50 are arranged at positions close to the filter rod rack 60. The in-and-out storage conveyors 50 are used to carry and convey filter rod boxes A, and the in-and-out storage conveyors 50 are configured to dock with a stacker 70 to warehouse a real filter rod box A1 loaded with filter rods or to take an empty filter rod box A2 out of the warehouse. The first lifting and positioning machine 20 is arranged on the longitudinal rear side of the truck 10 and is used to dock with a target vehicle-mounted conveyor among the plurality of vehicle-mounted conveyors. The second lifting and aligning machine 40 is disposed at the longitudinal front side of the in-and-out conveyor 50 to dock with a target in-and-out conveyor among the plurality of in-and-out conveyors 50. The buffer conveying device 30 is disposed between the first lifting and aligning machine 20 and the second lifting and aligning machine 40.

[0035] The filter rod box warehousing and unloading system provided by the embodiment of the utility model utilizes a special truck 10 to load the real filter rod box with filter rods and moves it to the position docking with the first lifting and positioning machine 20, and then the real filter rod box is sequentially passed through the first lifting and positioning machine 20, the buffer conveying device 30, the second lifting and positioning machine 40 and the warehousing and unloading conveying device 50 to complete the warehousing of the real filter rod box, and the empty filter rod box is reversely conveyed out of the warehouse through reverse conveying, which greatly improves the efficiency compared with the manual loading and unloading technology of the prior art.

[0036] refer to Figure 2In some embodiments, the truck 10 further includes two guide wheels 12 disposed at the bottom of the carriage and respectively located at both ends of the transverse direction x of the truck 10. The guide wheels 12 are disposed at the rear side of the wheels of the truck 10. The filter rod box storage and retrieval system further includes two guide rails 13 disposed corresponding to the two guide wheels 12. When the truck 10 moves in a direction approaching the first lifting and positioning machine 20, the guide wheels 12 are configured to move along the guide rails 13 and abut against the guide rails 13. In this way, when the truck 10 moves backward into position, the guide wheels 12 located at the rear side of the wheels will abut against the guide rails 13, thereby preventing the height of the carriage from being affected by the height of the wheels and failing to reach the set height. For example, the wheels may have different heights under different pressures and temperatures, which results in different heights of the carriage, and the set height for docking with the first lifting and positioning machine 20 cannot be reached. The truck of the embodiment of the utility model is provided with a guide wheel located at the rear side of the wheel, and the guide wheel is in contact with the guide rail. In this way, regardless of the state of the wheel, the truck can be retreated to a set position as long as the guide wheel is in contact with the guide rail, thereby making the car body at a set height.

[0037] In some embodiments, Figure 2 As shown, the guide rail 13 includes an inclined section and a flat section located at the rear side of the inclined section, and the guide wheel first moves upward along the inclined section and then moves to the flat section to stop. Therefore, the guide wheel abuts against the flat section, and the height of the flat section is fixed, and the guide wheel is also rigid, so it can be ensured that the carriage of the truck 10 can be parked at the same height every time.

[0038] In some embodiments, the in-and-out system further includes fences disposed on both lateral sides of the truck 10. In the direction extending from the front to the rear, the fences are in a constricted shape, so that the truck 10 is limited and guided by the fences during the backward movement.

[0039] refer to Figure 2 In some embodiments, the buffer conveyor device 30 includes a suspended platform and a buffer conveyor disposed on the platform. The buffer conveyor device 30 of the utility model embodiment is provided with a suspended platform, so that the area below the platform can become an operating area for operators.

[0040] refer to Figure 1 , the buffer conveying device 30 includes a plurality of buffer conveyors arranged on the platform. The plurality of buffer conveyors are arranged at intervals in the transverse direction x, and the plurality of buffer conveyors include an inbound buffer conveyor for conveying the solid filter rod box from front to back into the warehouse and an outbound buffer conveyor for conveying the empty filter rod box from back to front out of the warehouse. That is to say, during the inbound and outbound processes, the buffer conveyors that are docked with the first lifting alignment machine 20 are different buffer conveyors, so the alignment body of the first lifting alignment machine 20 of this embodiment needs to move to the position of different buffer conveyors in the transverse direction x to complete the docking.

[0041] refer to Figure 4 In some embodiments, a plurality of shelves spaced apart in the height direction are provided in the carriage. A plurality of vehicle conveyors 11 spaced apart in the transverse direction x are provided on each shelf. In order to enable the first lifting and aligning machine 20 to accurately align with the target vehicle conveyor among the vehicle conveyors 11, in some embodiments, the filter rod box storage and unloading system further includes a reflector 12 provided on the target vehicle conveyor, a detection member provided on the first lifting and aligning machine 20, and a controller. When the detection member detects the reflector 12 on the target vehicle conveyor, the controller is configured to control the target vehicle conveyor to move so as to transport the filter rod box to the first lifting and aligning machine.

[0042] The first lifting alignment machine 20 includes an alignment body, which aligns the alignment body with the position of the vehicle conveyor 11, and then starts the vehicle conveyor 11 to transport the real filter rod box on the vehicle conveyor 11 to the alignment body. Then the alignment body itself is also movable in the longitudinal direction y, and continues to transport the real filter rod box to the cache conveying device 30.

[0043] In some embodiments, each vehicle-mounted conveyor includes a plurality of conveying sections arranged sequentially in the longitudinal direction y. The plurality of conveying sections sequentially convey the filter rod boxes carried by each of them to the first lifting and alignment machine 20 .

[0044] Multiple conveying sections are arranged in sequence in the longitudinal direction y. Therefore, when the target vehicle-mounted conveyor conveys the real filter rod box to the first lifting and positioning machine 20, multiple conveying sections need to be conveyed in sequence along the longitudinal direction y. In order to ensure that after the conveying section located on the rear side of the longitudinal direction has conveyed all the real filter rod boxes, the conveying section located on the front side continues to convey them, in some embodiments, the filter rod box in and out of the storage system also includes a first photoelectric switch and a second photoelectric switch respectively arranged at both ends of the diagonal of each conveying section, and one of the first photoelectric switch and the second photoelectric switch is configured to detect the other to determine whether there are any real filter rod boxes left on the conveying section that have not been conveyed out.

[0045] Specifically, when there are still real filter rod boxes that have not been transported out on the conveying section, the remaining real filter rod boxes will block the detection path between the first photoelectric switch and the second photoelectric switch, so there is no way for each other to detect the other photoelectric switch. When the first photoelectric switch and the second photoelectric switch can detect each other, it means that there are no real filter rod boxes that have not been transported out on the conveying section, that is, all the real filter rod boxes on the conveying section have been transported out, so transportation can continue. For example, multiple conveying sections include a first conveying section, a second conveying section, and a third conveying section, wherein the first conveying section is located at the rear end of the carriage, then only after it is detected that all the real filter rod boxes on the first conveying section have been transported, can the transportation of the second conveying section be started. Therefore, the embodiment of the utility model can ensure the effective connection between the various conveying sections and improve the efficiency and quality of transportation by setting diagonally arranged photoelectric switches on each conveying section.

[0046] In some embodiments, the buffer conveying device 30 includes an inbound buffer conveyor and an outbound buffer conveyor spaced apart in the transverse direction x. The inbound buffer conveyor is configured to first dock with the first lifting and positioning machine 20 to receive the real filter rod boxes on the target vehicle conveyor. After the target vehicle conveyor transports all the real filter rod boxes to the inbound buffer conveyor through the first lifting and positioning machine 20 and makes the target vehicle conveyor empty, the outbound buffer conveyor is configured to dock with the first lifting and positioning machine 20 to transport the cached empty filter rod boxes to the empty target vehicle conveyor.

[0047] Specifically, Figure 3 As shown, each layer of the carriage 10 is provided with three on-board conveyors spaced apart in the transverse direction x. When leaving the warehouse, the real filter rod boxes on one of the on-board conveyors are sequentially conveyed backwards along the longitudinal direction to the warehouse-entry buffer conveyor, so that there are no real filter rod boxes on the on-board conveyor, that is, it is empty, and then the empty filter rod boxes cached on the warehouse-exit buffer conveyor can be conveyed to the newly empty on-board conveyor through the first lifting alignment machine 20. After completing the above actions, continue to perform the warehouse-leaving operation on the real filter rod boxes on the other on-board conveyor.

[0048] In some embodiments, reference Figure 7 and Figure 8The filter rod box is a square structure, and the square structure includes a bottom wall, a first side wall and a second side wall connected to the bottom wall and arranged oppositely, and a third side wall arranged between the first side wall and the second side wall. The opposite ends of the bottom wall are open and the opposite ends of the third side wall are open to form an opening. Each vehicle-mounted conveyor carries a plurality of real filter rod boxes arranged in sequence. The plurality of real filter rod boxes include a real filter rod box at the rearmost end in the longitudinal direction y and the remaining real filter rod boxes, the opening of the real filter rod box at the rearmost end is arranged forward, and the openings of the remaining real filter rod boxes are arranged backward. Such an arrangement not only ensures that the opening of the real filter rod box at the rearmost end is arranged forward to prevent the filter rod placed therein from falling under the action of inertia, but also sets the openings of the remaining real filter rod boxes backward, which can also ensure the uniformity of warehousing and the convenience of picking up goods after warehousing.

[0049] In some embodiments, the filter rod box storage and unloading system further includes a visual device. The visual device is used to visually identify each real filter rod box containing filter rods during the process of the storage and unloading conveyor 50 conveying multiple real filter rod boxes into the storage to determine whether the opening of the real filter rod box is set forward or backward. If the opening of the filter rod box is set forward, the real filter rod box is rotated so that the opening is set backward for storage.

[0050] In some embodiments, the in-and-out warehouse conveyor includes a first conveyor line body and a second conveyor line body spaced apart in the transverse direction, and a gap is provided between the first conveyor line body and the second conveyor line body, and the filter rod box in-and-out warehouse system also includes a turntable 55 provided below the in-and-out warehouse conveyor. The turntable 55 is configured to be movably provided in the height direction to extend to the gap or retract from the gap, and if the visual device determines that the opening of the filter rod box is set forward, the turntable is configured to extend to the gap to receive the actual filter rod box and rotate so that the opening of the actual filter rod box is set backward.

[0051] Specifically, the first conveyor line body and the second conveyor line body are conveyed synchronously, that is to say, the filter rod box is supported and conveyed by the first conveyor line body and the second conveyor line body during the conveying process. Moreover, there is a gap between the first conveyor line body and the second conveyor line body, that is, the middle is empty. The turntable 55 is arranged at the gap and is telescopically arranged in the height direction. When the visual device detects that the opening of the real filter rod box is facing forward, the turntable is controlled to rise to lift up the real filter rod box, so that the filter rod box is supported by the turntable, and then the turntable is controlled to rotate to drive the real filter rod box to rotate so that its opening faces backward, and then the turntable is controlled to descend to land the real filter rod box on the storage conveyor for continued transportation.

[0052] In some embodiments, after the turntable rotates, it is necessary to further detect the opening direction of the actual filter rod box through a visual device to determine whether it is turned into place. If it is turned into place, the in-and-out conveyor is controlled to continue conveying.

[0053] In some embodiments, the visual device includes an image acquisition device and a controller, wherein the image acquisition device is used to acquire an image of the end face of the real filter rod box close to the shelf 60, and then the controller receives the image acquired by the image acquisition device and analyzes it to determine the opening direction of the real filter rod box.

[0054] The present utility model also provides a method for loading and unloading a filter rod box based on the loading and unloading system, comprising the following steps:

[0055] Control the truck 10 loaded with the real filter rod box A1 to move backward to approach the first lifting and positioning machine 20;

[0056] According to the position of the target vehicle-mounted conveyor, the first lifting and aligning machine 20 is controlled to move the aligning body so that the aligning body is docked with the target vehicle-mounted conveyor;

[0057] Controlling the target vehicle-mounted conveyor to move the plurality of real filter rod boxes A1 carried thereon to the buffer conveying device 30 through the alignment body in sequence; and

[0058] The buffer conveying device 30 conveys the solid filter rod box A1 to the second lifting and positioning machine 40 , and conveys it to the storage-in and -out conveyor 50 through the second lifting and positioning machine 40 , and then enters the storage through the stacker 70 .

[0059] The warehousing and unloading method provided by the embodiment of the utility model utilizes a special truck 10 to load a real filter rod box containing filter rods and moves it to a position docking with a first lifting and positioning machine 20, and then the real filter rod box is sequentially passed through the first lifting and positioning machine 20, the buffer conveying device 30, the second lifting and positioning machine 40 and the warehousing and unloading conveying device 50 to complete the warehousing of the real filter rod box, and the empty filter rod box is reversely conveyed out of the warehouse through reverse conveying, which greatly improves the efficiency compared with the manual loading and unloading technology of the prior art.

[0060] In some embodiments, the warehousing method further includes: after all the solid filter rod boxes A1 on the target vehicle conveyor are transported to the buffer conveyor device 30, the empty filter rod boxes A2 are transported to the vacant target vehicle conveyor. The warehousing method of the embodiment of the utility model transports the cached empty filter rod boxes to the target vehicle conveyor after it is vacant, thereby allowing more empty filter rod boxes to be cached on the buffer conveyor device 30, thereby improving the space utilization rate of the warehousing system of the embodiment and the operation efficiency of the entire warehousing and warehousing.

[0061] In some embodiments, the warehousing and unloading method also includes loading multiple real filter rod boxes onto the vehicle-mounted conveyor 11 in sequence. For each vehicle-mounted conveyor 11, the real filter rod box located at the rear end in the longitudinal direction y is set opposite to the other real filter rod boxes, and the opening of the real filter rod box at the rear end is set forward, and the openings of the remaining real filter rod boxes are set backward.

[0062] In some embodiments, the warehousing and unloading method also includes: in the process of the warehousing and unloading conveyor 50 conveying multiple real filter rod boxes into the warehouse, each real filter rod box containing filter rods is visually identified to determine whether the opening of the real filter rod box is facing forward or backward; if the opening of the filter rod box is facing forward, the real filter rod box is rotated so that the opening is facing backward for warehousing.

[0063] According to the following Figures 1 to 8 The structure and working process of a filter rod box storage and unloading system according to a specific embodiment of the utility model are described in detail.

[0064] like Figure 1 As shown, in the description of this embodiment, the longitudinal direction y refers to the conveying direction of the filter rod box during the storage and unloading process, and the transverse direction x is perpendicular to the longitudinal direction y. Among them, taking the truck 10 as a reference, the direction where the front of the truck 10 is located is the longitudinal front end, and the direction where the compartment of the truck 10 is located is the longitudinal rear end.

[0065] like Figure 1 and Figure 2 As shown, the filter rod box storage and unloading system of this embodiment includes a truck 10, a first lifting and positioning machine 20, a buffer conveying device 30, a second lifting and positioning machine 40 and a storage and unloading conveyor 50 which are arranged in sequence in the longitudinal direction y.

[0066] The filter rod box storage and unloading system of this embodiment is used to transport a full filter rod box loaded with filter rods into the storage or to transport an empty filter rod box out of the storage.

[0067] The in-and-out conveyor 50 is disposed close to the shelf 60 to cooperate with the stacker 70 to store the solid filter rod boxes.

[0068] like Figure 2 As shown, the truck 10 includes a carriage. The carriage 10 has a door at the rear end. A plurality of shelves are arranged in layers in the height direction in the carriage, and each shelf is provided with a plurality of on-board conveyors 11 arranged at intervals in the transverse direction x. Each on-board conveyor 11 includes a plurality of conveying sections arranged in sequence in the longitudinal direction y. Figure 3 The carriage 10 is exemplarily shown to be provided with three onboard conveyors at intervals in the transverse direction, and each onboard conveyor 11 includes three conveying sections arranged sequentially in the longitudinal direction y. When the solid filter rod box is conveyed outward, the three conveying sections of each onboard conveyor 11 convey outward sequentially.

[0069] Since the weight of the goods to be loaded and unloaded is not large, a special truck is used. A multi-layer, parallel, multi-stage on-board conveyor is installed in the compartment of the truck. In order to prevent the last end of the real filter rod box from falling due to inertia due to braking and other reasons during transportation, the last end of the real filter rod box will be placed upside down when loading the real filter rod box.

[0070] Specifically, Figure 7 and Figure 8 As shown in the figure, the filter rod box is a square structure. Figure 8 As shown, the empty filter rod box A2 is a square structure, including a bottom wall, a first side wall and a second side wall connected to the bottom wall and arranged oppositely, and a third side wall arranged between the first side wall and the second side wall. The opposite ends of the bottom wall are open and the opposite ends of the third side wall are open to form an opening. Therefore, if the opening of the real filter rod box located at the rear end is arranged to face backward, when braking, the filter rod in the real filter rod box is very likely to fall out of the opening under the action of inertia. Therefore, in order to avoid the filter rod from falling, each vehicle-mounted conveyor carries a plurality of real filter rod boxes arranged in sequence, and the plurality of real filter rod boxes include the real filter rod box located at the rear end in the longitudinal direction y and the remaining real filter rod boxes, the opening of the real filter rod box at the rear end is arranged to face forward, and the opening of the remaining real filter rod boxes is arranged to face backward. This arrangement ensures that the opening of the rearmost real filter rod box is facing forward to prevent the filter rod placed therein from falling due to inertia, and the openings of the remaining real filter rod boxes are all facing backward to ensure uniform warehousing and convenience in picking up goods after warehousing.

[0071] It can be seen from the above description that each vehicle-mounted conveyor 11 includes a plurality of conveying sections arranged in sequence in the longitudinal direction y. For example, the plurality of conveying sections include a first conveying section, a second conveying section, and a third conveying section arranged in sequence from front to back in the longitudinal direction y. After the third conveying section at the rear end runs first and conveys all the real filter rod boxes thereon, the second conveying section in the middle first conveys the real filter rod boxes to the third conveying section and continues to convey them to the first lifting and positioning machine. Finally, the first conveying section at the front end is used for conveying. Therefore, during the conveying process, it is necessary to detect whether the real filter rod boxes on each conveying section have been run through to prevent the filter rod boxes from being left behind.

[0072] When the filter rod box is put in and taken out of the warehouse, the truck 10 is loaded with a real filter rod box with filter rods, and the truck 10 needs to dock with the first lifting and positioning machine at the rear side to complete the storage of the real filter rod box. In order to improve the moving accuracy of the position of the truck 10 when it moves backward, a guide wheel 12 is installed under the compartment of the truck 10, and a guide rail 13 is set on the ground. When loading and unloading, the truck 10 moves backward and under the action of the driving force, the guide wheel 12 of the truck 10 will move backward along the guide rail on the ground until it moves backward into place.

[0073] Specifically, a position sensor is provided to detect the position of the truck 10 . When the truck 10 has reversed to a certain position, the position sensor will send a signal, and then the truck 10 will stop reversed.

[0074] After the truck 10 backs up into position, operate on the console of the first lifting and positioning machine 20 and select "truck in place", and select "start unloading" on the console according to the number of the target vehicle conveyor to be unloaded and the brand information of the corresponding filter rods. After the first lifting and positioning machine 20 moves to the position of the corresponding conveyor according to the number of the target vehicle conveyor for alignment, the real filter rod boxes are transported from the vehicle conveyor of the truck 10 to the first lifting and positioning machine 20. Then the first lifting and positioning machine 20 transports the real filter rod boxes on the alignment body to the storage cache station. When all the real filter rod boxes on a vehicle conveyor are unloaded, the first lifting and positioning machine will receive the empty filter rod boxes from the outbound cache conveyor and transport them to the vehicle conveyor with the corresponding number until the conveyor is full. Similarly, the loading and unloading of real filter rod boxes and empty filter rod boxes of other vehicle conveyors are completed.

[0075] like Figure 2 As shown, the buffer conveying device 30 includes a suspended platform and a buffer conveyor arranged on the platform. Figure 1 As shown, the buffer conveyor includes an inbound buffer conveyor and an outbound buffer conveyor which are spaced apart in the transverse direction x. The inbound buffer conveyor is used to convey the solid filter rod boxes into the warehouse, and the outbound buffer conveyor is used to convey the empty filter rod boxes out of the warehouse.

[0076] The buffer conveying device 30 of this embodiment is suspended, so that a working area can be formed under the platform, that is, workers may pass through, so the platform adopts a steel platform structure.

[0077] like Figure 1 As shown, different buffer conveyors correspond to different in-and-out warehouse conveyors 50, so another lifting and positioning machine, namely the second lifting and positioning machine, is installed between the buffer conveyor device 30 and the in-and-out warehouse conveyor 50. The second lifting and positioning machine determines whether the real filter rod box on the in-warehouse buffer conveyor is transported to the corresponding in-and-out warehouse conveyor 50 according to the brand of the in-and-out warehouse conveyor 50 and whether it is idle. The in-and-out warehouse conveyor 50 transports the external real filter rod box and checks the RFID information, and judges the real filter rod box through appearance inspection and other technologies. Check whether the filter rod box is reversed. For the reversed filter rod box, the turntable 55 is rotated back, and the conveyor is forwarded after the information and direction are consistent with the preset target. After the number of filter rod boxes conveyed forward is controlled by the filter rod box clamping device to reach the A disk, if A is less than the preset number of filter rod box group B, the filter rod box clamping device continues to convey the filter rod box forward; if A is consistent with the preset number B of the filter rod box group, an application is made for warehousing; the stacker forks the external filter rod box and places it in the corresponding cargo position; if A is greater than B, the equipment alarm needs manual processing.

[0078] like Figure 5 and Figure 6As shown, the empty filter rod box can be applied for outbound storage in the same way. The stacker will fork the empty filter rod box from the corresponding cargo position and place it on the inbound and outbound conveyor 50. The inbound and outbound conveyor 50 will convey the empty filter rod box forward, and the number of empty filter rod boxes will be controlled by the filter rod box clamping device to form a new group of empty filter rod boxes. The new group of empty filter rod boxes will be at the docking point with the second lifting and positioning machine, and the second lifting and positioning machine will transfer the empty filter rod box to the outbound buffer conveyor, waiting to be conveyed forward when the vehicle-mounted conveyor is empty.

[0079] The warehousing and out-of-warehouse system of this embodiment is provided with two lifting and positioning machines, which adopt the lifting and positioning machines commonly used in this technical field. Its positioning body can move in the height direction and the lateral direction x to determine its moving distance through the position of the coordinates, thereby realizing docking with the vehicle-mounted conveyor, the buffer conveyor and the warehousing and out-of-warehouse conveyor 50.

[0080] The RFID chip is used to store the information of the filter rod including brand, specification, production date, production bus, production machine, etc.

[0081] The visual device determines whether the position of the actual filter rod box is reversed by identifying the shape or grayscale of the filter rod box and the filter rod. It can also use AI and other technologies to identify whether the turntable returns to a position consistent with the direction of other actual filter rod boxes and stops rotating after they are consistent.

[0082] The storage-in and storage-out method of the storage-in and storage-out system of this embodiment is as follows:

[0083] After the filter rod production center produces the filter rods, the filter rods are loaded into empty filter rod boxes, and the full filter rod boxes are loaded into special trucks. After the special truck carries the full filter rod boxes from the filter rod production center to the outer platform of the filter rod warehouse shelf, the driver backs up the special truck. Under the action of the driving force, the guide wheels of the truck will move backward along the ground guide rails until they are backed into place. At this time, the on-board conveyor is aligned with the lifting alignment machine.

[0084] After the special truck backs up into position, perform relevant operations on the operating console on the first lifting and aligning machine, select "Truck in place", and select the conveyor number and corresponding brand information to be unloaded, the conveyor number and corresponding brand information of the empty filter rod box to be loaded, and select the specifications and models of the foreign real filter rod box. Select "Start unloading", and the first lifting and aligning machine will align according to the conveyor number of the unloading. After the photoelectric switch of the first lifting and aligning machine detects the reflector of the target vehicle-mounted conveyor, the target vehicle-mounted conveyor will transport the foreign real filter rod box to the first lifting and aligning machine. When the foreign real filter rod box of the first conveying section on the outermost side of the target vehicle-mounted conveyor is transported to the first lifting and aligning machine, the first lifting and aligning machine will transport the foreign real filter rod box on the main body to the buffer conveying device 30. At the same time, the second conveying section in the middle continues to convey the external real filter rod boxes to the first conveying section to wait for the first lifting and positioning machine to take away the real filter rod boxes on the first conveying section again. Similarly, the real filter rod boxes on the third conveying section are moved to the cache conveying device 30 through the first lifting and positioning machine.

[0085] When the target vehicle conveyor is empty, the first lifting and positioning machine transports the empty filter rod box to the target vehicle conveyor, and specifically, first transports it to the first conveying section, and then the first conveying section transports the empty filter rod box group to the third conveying section, and so on until the conveyor is full.

[0086] Similarly, the external full filter rod boxes from other conveyors are moved to the buffer conveyor through the lifting and positioning machine, and the empty filter rod boxes are moved to the vehicle conveyor.

[0087] After the actual filter rod box is transported to the cache conveyor device 30, since different cache conveyors of the cache conveyor device 30 correspond to different in-and-out warehouse conveyors, and different in-and-out warehouse conveyors open filter rod boxes of the same or different brands for in-and-out warehouse, another lifting and positioning machine is installed between the cache conveyor device 30 and the in-and-out warehouse conveyor. The second lifting and positioning machine determines whether to convey the external filter rod box of the cache conveyor to the corresponding in-and-out warehouse conveyor according to the brand of the in-and-out warehouse conveyor transporting in and out of the warehouse and whether it is idle.

[0088] After the second lifting and positioning machine receives the external real filter rod box group and the corresponding information from the buffer conveying device 30 and conveys them to the in-and-out warehouse conveyor, the in-and-out warehouse conveyor moves the N real filter rod boxes and the corresponding information to the platform, and clamps the filter rod box through the filter rod box hook. At this time, the information of the external real filter rod box is checked through RFID. After the verification is consistent, the filter rod box hook is released, and the filter rod box with consistent information is conveyed forward. After the filter rod box behind is added, the filter rod box hook is clamped again for RFID information comparison. During the forward conveying of the filter rod box with consistent information, visual technology is used to identify whether the real filter rod box is an inverted filter rod box. If it is an inverted filter rod box, it is conveyed to the turntable and stopped. The turntable rotates and flips the real filter rod box to make it consistent with other filter rod boxes, and then continues to convey it forward. If it is not an inverted filter rod box, it continues to convey forward and accumulates. After the number of filter rod boxes conveyed forward controlled by the filter rod box clamping device reaches tray A, if A is less than B, the filter rod box clamping device continues to convey the filter rod boxes forward; if A is greater than B, the equipment alarm requires manual processing; if A is consistent with the preset tray B number, an application for warehousing is made; the stacker forks the external filter rod boxes and places them in the corresponding cargo position.

[0089] You can apply for empty filter rod boxes to be shipped out of the warehouse. The stacker will take the empty filter rod boxes from the corresponding cargo position and place them on the in-and-out warehouse conveyor. The in-and-out warehouse conveyor will transport the empty filter rod boxes forward, and the number of filter rod boxes will be controlled by the filter rod box clamping device. The empty filter rod boxes will be reassembled into each group of N empty filter rod boxes. The new group of N empty filter rod boxes will be transported to the docking point with the second lifting and positioning machine. The second lifting and positioning machine will transfer the empty filter rod boxes to the out-of-warehouse buffer conveyor. Wait for the vehicle-mounted conveyor to be transported forward when it is empty.
