Description

Technical Field

[0001] This invention relates to the field of warehousing and handling technology, specifically to an automated stacking equipment for digital factory logistics warehousing. Background Technology

[0002] Warehouse stacking is a core aspect of goods storage in warehouse management. It refers to stacking goods on pallets, shelves, or the ground in a reasonable manner to maximize space utilization, ensure the safety of goods, and improve operational efficiency. With the development of technology, warehouse storage in factories can now be digitally controlled, that is, the operation of stacking equipment is automatically controlled by programs.

[0003] In the prior art, Chinese patent application number CN202011567237.X discloses a stacker crane for logistics warehousing, including legs and forks. Casters are fixedly connected to the four corners of the bottom of the legs. Vertical plates are fixedly connected to both sides of the upper end of the legs. A top plate is fixedly connected to the top of the two vertical plates. A limiting mechanism is provided on one side of the top plate. A driving mechanism is provided at the top of the top plate. A lifting box is connected to the bottom of the driving mechanism through two connecting blocks. The lifting box is located between the two vertical plates. A third slider is fixedly connected to both sides of the lifting box. A third sliding groove is provided on the opposite side of the two vertical plates. The two third sliders are slidably connected to the corresponding third sliding groove. The forks are fixedly connected to the outside of the lifting box. A baffle is provided at the top of the forks. The goods are limited and protected by two second sets of plates to prevent the goods from sliding and falling from a height.

[0004] In the prior art, Chinese patent application number CN201910751112.3 discloses a stacker crane for logistics warehousing, including a column top rail, a lower guide rail I-beam, a fork extension mechanism, a lifting mechanism, and a horizontal driven walking box. The column top rail has a portal frame structure, which, together with the lower guide rail I-beam, forms the frame of the stacker crane. The horizontal driven walking box is installed on the lower guide rail I-beam through a slot and slides horizontally along the lower guide rail I-beam. The bottom end of the lifting mechanism is screwed to the upper end of the horizontal driven walking box, and the top end is connected to the upper end of the column top rail. The fork extension mechanism is installed on one side of the lifting mechanism, driving the fork extension mechanism to move up and down to realize the transportation of goods. The position of the goods is detected by the sensor of the fork extension mechanism, and the goods are transported by the forks through horizontal and vertical sliding. The detection and limiting function of the sensor realizes the automation of inbound and outbound operations.

[0005] In the prior art, Chinese Patent Application No. CN201210433651.0 discloses a stacker crane and a storage system. The stacker crane includes a lifting mechanism, forks, and a static elimination device. The lifting mechanism drives the forks and the static elimination device in a vertical direction. The static elimination device releases ionized air above the forks, which can eliminate static electricity on the items transported by the stacker crane. Thus, it can effectively control and eliminate static electricity in the storage system with the stacker crane.

[0006] Based on the above information, it can be seen that existing stacking equipment generally uses forklifts or pallets to handle goods. However, in actual use, when forklifts or pallets are handling goods, they are located on the side of the supporting structure. When the goods are lifted to a high position, it will cause the overall center of gravity of the device to shift, which may lead to a tipping hazard if there is no stabilizing mechanism. Summary of the Invention

[0007] The purpose of this invention is to provide an automated stacking device for digital factory logistics warehousing, so as to solve the problem of tipping caused by the shift of the center of gravity mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an automated stacking equipment for digital factory logistics warehousing, comprising a warehouse shelf and a placement platform placed on the ground, wherein a cargo component is placed on the placement platform, and the cargo component includes a support pallet and a cargo box placed on the support pallet; a first sliding base is provided on the front side of the warehouse shelf, and a second sliding base is installed on the top of the first sliding base; symmetrical first support columns are fixedly installed on the upper surface of the second sliding base, and a second support column is installed inside the first support column; a connecting horizontal plate is installed between the two second support columns, and a transport fork for supporting the support pallet is provided below the connecting horizontal plate; a telescopic mechanism is provided between the transport fork and the connecting horizontal plate; an installation plate is fixedly installed on the top of the connecting horizontal plate, and a storage box is fixedly installed on the outer surface of the connecting horizontal plate; a winding wheel is rotatably installed inside the storage box, and a tension rope is wound inside the winding wheel; the tension rope is made of steel wire rope.

[0009] Preferably, the first sliding base and the transverse slide rail fixedly installed on the ground form a left-right sliding structure, and the second sliding base and the longitudinal slide rail fixedly installed on the upper surface of the first sliding base form a front-back sliding structure. The sliding of the first sliding base and the second sliding base causes the entire device to move, thereby achieving the purpose of automatic control.

[0010] Preferably, a limiting groove is provided on the inner side of the first support column, and the second support column and the limiting groove form an up-and-down sliding structure. Furthermore, a first lead screw is rotatably installed inside the first support column and is threaded through the second support column. The rotation of the first lead screw drives the second support column to move up and down, thereby changing the overall height of the device.

[0011] Preferably, the lower end of the tension rope is fixedly installed on the upper surface of the fixed plate, and the fixed plate is fixedly installed on the upper surface of the first sliding base, thereby improving the stability of the device when transporting goods by utilizing the tension of the tension rope.

[0012] Preferably, the shaft of the winding reel is fixedly connected to a limit motor fixedly installed outside the storage box. A second lead screw and a limit slide are fixedly installed on the rear side of the two winding reels respectively. The limit motor maintains the tension of the tension rope, so that the handling fork can move and stack the cargo components. During the upward movement of the second support column, the tension rope is pulled, and the tension rope drives the winding reel to rotate.

[0013] Preferably, the telescopic mechanism includes a connecting slider fixedly installed inside the transport fork, the connecting slider sliding through and sliding with the limiting slider, and the connecting slider being threadedly connected to the second lead screw, the connecting slider being moved by rotating the second lead screw.

[0014] Preferably, the rear end of the transport fork and the limiting sleeve form a through sliding structure, the transport fork slides against the connecting cross plate, and the limiting sleeve is fixedly installed on the lower surface of the mounting plate. The transport fork is retracted by the connecting slider, and the transport fork is limited by the limiting sleeve fixedly installed on the lower surface of the mounting plate when it moves, thereby improving the strength of the transport fork during transport.

[0015] Preferably, a recognition camera for identifying barcode information of goods boxes is fixedly installed on the upper surface of the mounting plate, and pressurized cleaning nozzles are provided on the left and right sides of the recognition camera. The extrusion block compresses the air bladder inside the storage box. When the air bladder is compressed, the air inside is sprayed out from the cleaning nozzle through the connecting hose, thereby using the airflow to clean the surface of the recognition camera and avoid dust from obstructing the recognition camera surface, which would affect the recognition accuracy.

[0016] Preferably, the cleaning nozzle is connected to the blower airbag via a connecting hose, and the blower airbag is fixedly installed inside the storage box. The position of the blower airbag corresponds to the position of the winding wheel, and a protruding compression block is fixedly installed on the side of the winding wheel, and the compression block and the blower airbag compress each other.

[0017] Preferably, the connecting horizontal plate is rotatably connected to the second support column, and a pressure sensor and a buffer spring are provided between the lower surface of the connecting horizontal plate and the second support column, and the pressure sensor communicates with the limit motor via Bluetooth.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This automated stacking equipment for digital factory logistics warehousing adopts a novel structural design, the specific details of which are as follows:

[0019] 1. The first sliding base slides on the horizontal slide rail, and the second sliding base slides on the vertical slide rail. In conjunction with the first lead screw, the second support column moves up and down, so that the handling fork can move and stack the cargo components. During the upward movement of the second support column, the tension rope is pulled, and the tension rope drives the winding wheel to rotate. At this time, the limit motor provides a certain tension to improve the overall stability and avoid the danger of tipping over due to the shift of the center of gravity when the cargo is lifted.

[0020] Furthermore, when lifting goods, pressure sensors are used to detect the pressure difference between the front and rear sides of the connecting plate, and the data is transmitted to the limit motor. This allows the torque of the limit motor to be adjusted in real time, achieving a better tension stability effect. In addition, the non-rigid connection of the buffer spring can be buffered by a certain amount of force when it is impacted.

[0021] Furthermore, during the rotation of the winding reel, the second lead screw fixedly installed at its rear end rotates. During the rotation of the second lead screw, the connecting slider installed through its external thread moves, thereby using the connecting slider to drive the transport fork to move inward, moving the cargo assembly above the transport fork to a position closer to the first support column, thereby reducing the center of gravity offset.

[0022] Furthermore, the connecting slider is limited by a limiting slide rod that slides through it during movement, and the transport fork is limited by a limiting sleeve fixedly installed on the lower surface of the mounting plate during movement. The limiting is used to improve the strength of the transport fork during transport.

[0023] 2. Before handling, the identification camera fixedly installed on the upper surface of the mounting plate identifies the surface code of the cargo box, thereby accurately moving the cargo box to the stacking position;

[0024] Furthermore, as the winding wheel rotates, it drives the compression block fixedly installed on its side to rotate synchronously. This compression block compresses the air bladder inside the storage box. When the air bladder is compressed, the air inside is sprayed out from the cleaning nozzle through the connecting hose. This airflow cleans the surface of the recognition camera, preventing dust from obstructing the camera surface and affecting recognition accuracy. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1-5To achieve automated handling and stacking, this embodiment provides the following technical solution, specifically disclosing: a warehouse shelf 1 and a placement platform 2 placed on the ground; a goods assembly 3 is placed on the placement platform 2, and the goods assembly 3 includes a support pallet 301 and a goods box 302 placed on the support pallet 301; a first sliding base 4 is provided on the front side of the warehouse shelf 1, and a second sliding base 6 is installed on top of the first sliding base 4; symmetrical first support columns 8 are fixedly installed on the upper surface of the second sliding base 6, and second support columns 9 are installed inside the first support columns 8. A connecting horizontal plate 12 is installed between the two sides, and a transport fork 13 for supporting the support pallet 301 is provided below the connecting horizontal plate 12. The first sliding base 4 and the horizontal slide rail 5 fixedly installed on the ground form a left-right sliding structure, and the second sliding base 6 and the longitudinal slide rail 7 fixedly installed on the upper surface of the first sliding base 4 form a front-back sliding structure. A limiting slide groove 10 is opened on the inner side of the first support column 8, and the second support column 9 and the limiting slide groove 10 form an up-down sliding structure. A first lead screw 11 that is threaded through and connected to the second support column 9 is rotatably installed inside the first support column 8.

[0039] When using the device, firstly, the cargo assembly 3 is placed on the placement platform 2 using a conveying device (such as a conveyor belt). Then, the first sliding base 4 and the second sliding base 6 are opened, so that the first sliding base 4 slides on the transverse slide rail 5 and the second sliding base 6 slides on the longitudinal slide rail 7. Finally, the handling fork 13 is inserted under the support pallet 301 in the cargo assembly 3. Then, the motor inside the second sliding base 6 drives the first lead screw 11 to rotate. The first lead screw 11 drives the second support column 9, which is installed with a through thread on its outside, to slide upward in the limiting slide groove 10, thereby lifting the cargo assembly 3 upward (during the upward movement of the second support column 9, it drives the connecting cross plate 12 on its inner side to move, thereby driving the handling fork 13 to move along the line). Then, the device moves to place the cargo assembly 3 on the warehouse shelf 1 to achieve the purpose of stacking. During this process, the entire device is digitally and automatically controlled.

[0040] Please see Figures 6-9To improve stability during handling, this embodiment provides the following technical solution: A mounting plate 14 is fixedly installed above the connecting horizontal plate 12; a storage box 15 is fixedly installed on the outer surface of the connecting horizontal plate 12; a winding wheel 16 is rotatably installed inside the storage box 15; a tension rope 17 is wound inside the winding wheel 16; the tension rope 17 is made of steel wire rope; the lower end of the tension rope 17 is fixedly installed on the upper surface of a fixing plate 18; the fixing plate 18 is fixedly installed on the upper surface of the first sliding base 4; the shaft of the winding wheel 16 is fixedly connected to a limit motor 1601 fixedly installed outside the storage box 15; a second lead screw 19 and a limit slide bar 20 are fixedly installed on the rear sides of the two winding wheels 16 respectively; and a handling fork 1... A telescopic mechanism is provided between the connecting horizontal plate 12 and the 3. The telescopic mechanism includes a connecting slider 21 fixedly installed inside the transport fork 13. The connecting slider 21 slides through the limiting slider 20, and the connecting slider 21 is threadedly connected to the second lead screw 19. The rear end of the transport fork 13 and the limiting sleeve 22 form a through sliding structure. The transport fork 13 and the connecting horizontal plate 12 slide against each other, and the limiting sleeve 22 is fixedly installed on the lower surface of the mounting plate 14. The connecting horizontal plate 12 is rotatably connected to the second support column 9. A pressure sensor 28 and a buffer spring 29 are provided between the lower surface of the connecting horizontal plate 12 and the second support column 9. The pressure sensor 28 communicates with the limiting motor 1601 via Bluetooth.

[0041] As the connecting horizontal plate 12 moves upward, it drives the mounting plate 14 above it to move synchronously. During the upward movement of the mounting plate 14, the tension rope 17 (the bottom end of the tension rope 17 is fixedly connected to the fixed plate 18) is pulled. At this time, the tension rope 17 drives the winding wheel 16 inside the storage box 15 to rotate. The winding wheel 16 is positioned at the lower left and right limits of the limit motor 1601, thus maintaining the tension of the tension rope 17, thereby pulling the entire stabilizing device and preventing the risk of tipping over when the cargo assembly 3 is lifted. (When lifting the cargo, the pressure sensor 28 detects the pressure difference between the front and rear sides of the connecting horizontal plate 12, and transmits the data to the limit motor 1601, thereby adjusting the torque of the limit motor 1601 in real time to achieve better tension stability.) The effect is that the non-rigid connection of the buffer spring 29 can be buffered by a certain amount of force when it is impacted. During the rotation of the winding wheel 16 (that is, when the cargo assembly 3 moves upward), it drives the second lead screw 19 fixedly installed behind it to rotate. During the rotation of the second lead screw 19, it drives the connecting slider 21 with its external through thread to slide (the connecting slider 21 is limited by the limiting slide rod 20 during the sliding process). The connecting slider 21 drives the transport fork 13 to move (the transport fork 13 is limited by the limiting sleeve 22 fixedly installed on the lower surface of the mounting plate 14 during the movement). This causes the transport fork 13 to retract inward, so that the transport fork 13 moves the cargo assembly 3 to a position closer to the first support column 8, thereby improving the overall stability of the device.

[0042] Please see Figure 6 and Figure 10 In order to achieve the purpose of cleaning the camera, this embodiment provides the following technical solution, which specifically discloses: an identification camera 23 for identifying the barcode information of the cargo box 302 is fixedly installed on the upper surface of the mounting plate 14, and a pressurized cleaning nozzle 24 is provided on the left and right sides of the identification camera 23. The cleaning nozzle 24 is connected to the blower air bag 25 through the connecting hose 26. The blower air bag 25 is fixedly installed inside the storage box 15. The position of the blower air bag 25 corresponds to the position of the winding wheel 16. A pressing block 27 with a protruding structure is fixedly installed on the side of the winding wheel 16, and the pressing block 27 and the blower air bag 25 press against each other.

[0043] As the winding wheel 16 rotates, it drives the pressing block 27 on its side to rotate synchronously. During the rotation, the pressing block 27 intermittently presses the air bladder 25 inside the storage box 15. When the air bladder 25 is compressed, the air inside is sprayed out from the cleaning nozzle 24 through the connecting hose 26. The air blown out by the cleaning nozzle 24 is used to clean the dust on the surface of the identification camera 23 (the identification camera 23 is used to identify the barcode on the outer surface of the cargo box 302, determine the information of the cargo box 302, and thus help to stack the cargo box 302 to the designated position in the warehouse shelf 1).
