Description

Technical Field

[0001] The present invention relates to the technical field of warehousing handling, and particularly to an automated stacking device for digital factory logistics warehousing. Background Art

[0002] Warehouse stacking is the core link of goods storage in warehouse management, which refers to stacking goods on pallets, shelves or the ground in a reasonable way to maximize space utilization, ensure the safety of goods and improve operation efficiency. With the development of technology, nowadays the warehousing in factories can adopt digital control, that is, using programs to automatically control the stacking equipment to work.

[0003] In the prior art, a Chinese patent with the application number CN202011567237.X discloses a stacking machine for logistics warehousing, including support feet and a fork. Four corners of the bottom end of the support feet are fixedly connected with casters. Both sides of the upper end of the support feet are fixedly connected with vertical plates. The tops of the two vertical plates are fixedly connected with a top plate. A limiting mechanism is arranged on one side of the top plate. A driving mechanism is arranged on the top of the top plate. The bottom end of the driving mechanism is connected with a lifting box through two connecting blocks. The lifting box is located between the two vertical plates. Both sides of the lifting box are fixedly connected with third sliders. Third chutes are arranged on the opposite sides of the two vertical plates. The two third sliders are slidably connected with the corresponding third chutes. The fork is fixedly connected to the outside of the lifting box. A baffle is arranged at the upper end of the fork. The goods are limited and protected by two second sets of plates to prevent the goods from sliding and falling in the air.

[0004] In the prior art, a Chinese patent with the application number CN201910751112.3 discloses a stacking machine for logistics warehousing, including a column sky rail, a lower guide rail I-beam, a fork telescopic mechanism, a lifting mechanism, and a horizontal driven walking box body; the column sky rail is in a portal structure and forms the frame of the stacking machine with the lower guide rail I-beam arranged at the lower end; the horizontal driven walking box body is installed on the lower guide rail I-beam through a card 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 body, and the top end is connected to the upper end of the column sky rail; the fork telescopic mechanism is installed on one side of the lifting mechanism and drives the fork telescopic 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 telescopic mechanism, and the goods are grabbed by the fork and transported through horizontal and vertical sliding. The detection and limiting functions of the sensor realize the automation of warehousing and outbound.

[0005] In the prior art, a Chinese patent with the application number CN201210433651.0 discloses a stacking machine and a warehousing system. The stacking machine includes a lifting mechanism, a fork and an electrostatic elimination device. The lifting mechanism drives the fork and the electrostatic elimination device in the vertical direction. The electrostatic elimination device releases ionic wind above the fork, which can eliminate the static electricity on the items transported by the stacking machine; thus, it can effectively control and eliminate the static electricity in the warehousing system with this stacking machine.

[0006] Combined with the above materials, it can be seen that the stacking equipment in the prior art generally uses a forklift or a pallet to carry goods. However, in the actual use process, the forklift or the pallet is located on the side of the support structure when carrying goods. When the goods are lifted to a high place, it will cause the overall center of gravity of the device to shift, and there may be a tipping danger in the absence of a stabilizing mechanism. Summary of the Invention

[0007] The purpose of the present invention is to provide an automated stacking equipment for digital factory logistics warehousing to solve the problem of tipping caused by the center of gravity shift mentioned in the above background technology.

[0008] To achieve the above purpose, the present invention provides the following technical solution: An automated stacking equipment for digital factory logistics warehousing, including a warehouse shelf and a placement table placed on the ground. Above the placement table, there is a goods component, and the goods component includes a support tray and a goods box placed above the support tray; on the front side of the warehouse shelf, there is a first sliding base, and a second sliding base is installed above the first sliding base; on the upper surface of the second sliding base, symmetrically arranged first support columns are fixedly installed, and a second support column is installed inside the first support column. A connecting cross plate is installed between the two second support columns. Below the connecting cross plate, there is a handling fork rod for lifting the support tray. An expansion mechanism is arranged between the handling fork rod and the connecting cross plate; on the upper part of the connecting cross plate, a mounting plate is fixedly installed, and a storage box is fixedly installed on the outer surface of the connecting cross plate. Inside the storage box, a winding wheel is rotatably installed, and a pulling rope is wound inside the winding wheel. The pulling rope is made of steel wire rope material.

[0009] Preferably, the first sliding base and the horizontal slideway fixedly installed on the ground form a left-right sliding structure, and the second sliding base and the longitudinal slideway fixedly installed on the upper surface of the first sliding base form a front-back sliding structure. By using the sliding of the first sliding base and the second sliding base, the overall movement of the device is achieved, so as to achieve the purpose of automatic control.

[0010] Preferably, a limiting chute is opened inside the first support column, and the second support column and the limiting chute form an up-down sliding structure. And a first lead screw that is threadedly connected through the second support column is rotatably installed inside the first support column. By rotating the first lead screw, the second support column is driven to move up and down, thereby changing the overall height of the device.

[0011] Preferably, the lower end of the pulling rope is fixedly installed on the upper surface of the fixing plate, and the fixing plate is fixedly installed on the upper surface of the first sliding base. By using the pulling force of the pulling rope, the stability of the device when carrying goods is improved.

[0012] Preferably, the rotating shaft of the winding wheel is fixedly connected to a limit motor fixedly installed outside the storage box. The second screw rod and the limit slide rod are respectively fixedly installed at the rear sides of the two winding wheels. The limit motor is used to maintain the tension of the pulling rope, so that the handling fork rod can handle and stack the cargo components. When the second support column moves upward, the pulling rope is pulled, and the pulling rope drives the winding wheel to rotate.

[0013] Preferably, the telescopic mechanism includes a connecting slider fixedly installed inside the handling fork rod. The connecting slider is slidably penetrated by the limit slide rod, and the connecting slider is threadedly penetrated between the second screw rod. The second screw rod rotates to drive the connecting slider to move.

[0014] Preferably, a through-type sliding structure is formed between the rear end of the handling fork rod and the limit sleeve. The handling fork rod and the connecting cross plate slide relative to each other. The limit sleeve is fixedly installed on the lower surface of the mounting plate. The connecting slider drives the handling fork rod to contract. When the handling fork rod moves, it is limited by the limit sleeve fixedly installed on the lower surface of the mounting plate, so as to improve the strength of the handling fork rod during handling by using the limit.

[0015] Preferably, an identification camera for identifying the barcode information of the cargo box is fixedly installed on the upper surface of the mounting plate. Pressurized cleaning nozzles are arranged on both the left and right sides of the identification camera. The air bag in the storage box is squeezed by the extrusion block. When the air bag is squeezed, the air inside it is sprayed out from the cleaning nozzle through the connecting hose, so as to clean the surface of the identification camera by using the sprayed air flow, and avoid the surface of the identification camera being blocked by dust and affecting the identification accuracy.

[0016] Preferably, the cleaning nozzle is communicated with the air bag through the connecting hose. The air bag is fixedly installed inside the storage box. The position of the air bag corresponds to the position of the winding wheel. A convex-shaped extrusion block is fixedly installed on the side surface of the winding wheel, and the extrusion block and the air bag are mutually extruded.

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

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The automatic stacking equipment for digital factory logistics warehousing adopts a new structural design, and the specific content is as follows: 1. The first sliding base slides on the transverse slideway, and the second sliding base slides on the longitudinal slideway. In cooperation with the first lead screw, the second support column moves up and down, enabling the handling fork rod to handle 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, a certain pulling force is provided by the limit motor to improve the overall stability and avoid the risk of tipping due to the center of gravity deviation when the cargo is lifted. Furthermore, when lifting the cargo, the pressure sensor is used to detect the pressure difference between the front and rear sides of the connecting cross plate, and thus the data is transmitted to the limit motor, so as to adjust the torque of the limit motor in real time, achieving a better pulling force stability effect. And the non-rigid connection of the buffer spring can receive a certain buffer force when being impacted.

[0019] Furthermore, during the rotation of the winding wheel, the second lead screw fixedly installed at its rear end is driven to rotate. During the rotation of the second lead screw, the connection slider moves through the externally threaded installation on it. Thus, the connection slider drives the handling fork rod to move inwards, moving the cargo components above the handling fork rod to a position closer to the first support column, thereby reducing the center of gravity deviation. Even further, during the movement of the connection slider, it is limited by the limit slide rod that penetrates and slides through it. When the handling fork rod moves, it is limited by the limit sleeve fixedly installed on the lower surface of the mounting plate, using the limit to improve the strength of the handling fork rod during handling.

[0020] 2. Before handling, the identification camera fixedly installed on the upper surface of the mounting plate is used to identify the bar code on the outer surface of the cargo box, so as to accurately handle the cargo box to the stacking position. Furthermore, during the rotation of the winding wheel, the extrusion block fixedly installed on its side rotates synchronously. Thus, the extrusion block squeezes the air bag in the storage box, and when the air bag is squeezed, the air inside passes through the connecting hose and is ejected from the cleaning nozzle, thereby using the ejected air flow to clean the surface of the identification camera and avoiding the influence of dust blocking on the surface of the identification camera on the identification accuracy.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 - 5, in order to achieve the purpose of automatic handling and stacking in this embodiment, the following technical solutions are provided, specifically disclosed: a warehouse shelf 1 placed on the ground and a placement table 2. Above the placement table 2, there is a goods component 3, and the goods component 3 includes a support tray 301 and a goods box 302 placed above the support tray 301; on the front side of the warehouse shelf 1, there is a first sliding base 4, and a second sliding base 6 is installed above the first sliding base 4; on the upper surface of the second sliding base 6, symmetrically arranged first support columns 8 are fixedly installed, and a second support column 9 is installed inside the first support columns 8. A connecting cross plate 12 is installed between the two second support columns 9. Below the connecting cross plate 12, there is a handling fork rod 13 for lifting the support tray 301. A left-right sliding structure is formed between the first sliding base 4 and a transverse slideway 5 fixedly installed on the ground, and a front-back sliding structure is formed between the second sliding base 6 and a longitudinal slideway 7 fixedly installed on the upper surface of the first sliding base 4. A limiting chute 10 is opened inside the first support column 8, and an up-down sliding structure is formed between the second support column 9 and the limiting chute 10. And inside the first support column 8, a first lead screw 11 is rotatably installed and threadedly connected through the second support column 9.

[0025] When using the device, first use a conveying device (such as a conveyor belt, etc.) to place the goods component 3 on the placement table 2. Then, turn on the first sliding base 4 and the second sliding base 6, so that the first sliding base 4 slides on the transverse slideway 5, and the second sliding base 6 slides on the longitudinal slideway 7. Finally, insert the handling fork rod 13 under the support tray 301 in the goods component 3. Then, use the motor inside the second sliding base 6 to drive the first lead screw 11 to rotate, and use the first lead screw 11 to drive the second support column 9 threadedly installed outside it to slide upward in the limiting chute 10, thereby lifting the goods component 3 upward (during the upward movement of the second support column 9, it drives the connecting cross plate 12 inside it to move, thereby driving the handling fork rod 13 to move upward). Then, move the device to place the goods component 3 on the warehouse shelf 1 to achieve the purpose of stacking. During this process, the whole device is digitally automatically controlled.

[0026] Please refer to Figures 6 - 9, in order to achieve the purpose of improving the stability during handling in this embodiment, the following technical solutions are provided, and specifically disclosed: An installation plate 14 is fixedly installed above the connecting cross plate 12. A storage box 15 is fixedly installed on the outer surface of the connecting cross plate 12. A winding wheel 16 is rotatably installed inside the storage box 15. A tension rope 17 is wound around the inside of the winding wheel 16. The tension rope 17 is made of steel wire rope material. The lower end of the tension rope 17 is fixedly installed on the upper surface of the fixing plate 18, and the fixing plate 18 is fixedly installed on the upper surface of the first sliding base 4. The rotating 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 respectively fixedly installed behind the two winding wheels 16. A telescopic mechanism is provided between the handling fork rod 13 and the connecting cross plate 12. The telescopic mechanism includes a connecting slider 21 fixedly installed inside the handling fork rod 13. The connecting slider 21 slidably penetrates through the limit slide bar 20, and the connecting slider 21 is threadedly connected through the second lead screw 19. A through-type sliding structure is formed between the rear end of the handling fork rod 13 and the limit sleeve 22. The handling fork rod 13 and the connecting cross plate 12 slide relative to each other, and the limit sleeve 22 is fixedly installed on the lower surface of the installation plate 14. The connecting cross plate 12 is rotatably connected to the second support column 9, and a pressure sensor 28 and a buffer spring 29 are provided between the lower surface of the connecting cross plate 12 and the second support column 9. And the pressure sensor 28 communicates with the limit motor 1601 via Bluetooth.

[0027] During the upward movement of the connecting cross plate 12, it drives the installation plate 14 above it to move synchronously. During the upward movement of the installation plate 14, it pulls the tension rope 17 (the bottom end of the tension rope 17 is fixedly connected to the fixing plate 18). At this time, the tension rope 17 drives the winding wheel 16 inside the storage box 15 to rotate. The winding wheel 16 is limited by the limit motor 1601 left and right, so that the limit motor 1601 maintains the tension of the tension rope 17, thereby pulling the entire stabilizing device to avoid the risk of tipping when the cargo assembly 3 is lifted (when lifting the cargo, the pressure sensor 28 is used to detect the pressure difference between the front and rear sides of the connecting cross plate 12, and then the data is transmitted to the limit motor 1601, so as to adjust the torque of the limit motor 1601 in real time to achieve a better tension stability effect, and the non-rigid connection of the buffer spring 29 can receive a certain buffer force when being 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 threadedly installed outside it to slide (the connecting slider 21 is limited by the limit slide bar 20 during the sliding process). The handling fork rod 13 is driven to move by the connecting slider 21 (the handling fork rod 13 is limited by the limit sleeve 22 fixedly installed on the lower surface of the installation plate 14 during the movement), so that the handling fork rod 13 contracts inward, and the handling fork rod 13 moves the cargo assembly 3 to a position closer to the first support column 8, thereby improving the overall stability of the device.

[0028] Please refer to Figure 6 and Figure 10 In order to achieve the purpose of cleaning the camera in this embodiment, the following technical solutions are provided, specifically disclosed as follows: 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 pressurized cleaning nozzles 24 are arranged on both the left and right sides of the identification camera 23. The cleaning nozzles 24 are interconnected with the air bag 25 through a connecting hose 26, and the air bag 25 is fixedly installed inside the storage box 15. The position of the air bag 25 corresponds to the position of the winding wheel 16, and a convex-shaped extrusion block 27 is fixedly installed on the side of the winding wheel 16, and the extrusion block 27 and the air bag 25 are mutually extruded.

[0029] During the rotation of the winding wheel 16, the extrusion block 27 on its side rotates synchronously. During the rotation of the extrusion block 27, the air bag 25 inside the storage box 15 is intermittently extruded. When the air bag 25 is extruded, the air inside it is ejected from the cleaning nozzle 24 through the connecting hose 26, and 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 to determine the information of the cargo box 302, so as to help stack the cargo box 302 to the designated position in the warehouse shelf 1).
