Description

Technical Field

[0001] This utility model belongs to the field of metal sheet storage technology, specifically relating to a flexible intelligent stacking device for steel plates. Background Technology

[0002] Manufacturing plants and workshops need to purchase and store steel plates of different specifications for production purposes. Traditional steel plate warehouses have three major pain points:

[0003] 1. Mixing steel plates of different sizes makes them difficult to locate and poses a safety risk.

[0004] Management inconveniences: Steel plates come in various sizes, such as thicknesses between 10-30mm, widths between 1500-2500mm, and lengths between 6000-13000mm. If mixed storage is used, storage space cannot be flexibly adjusted according to the steel plate sizes, making inventory checks and locating specific sizes extremely difficult for warehouse managers. They need to spend more time and effort searching different areas for the required steel plates, reducing efficiency, increasing the risk of errors, and impacting the overall warehouse management and operational efficiency.

[0005] Safety risks: When steel plates of different sizes are forced to be placed in unsuitable spaces, the steel plates may become unstable, which may easily lead to accidents such as tipping over or slipping, threatening personnel and equipment in the warehouse.

[0006] 2. Low scheduling efficiency

[0007] Information transmission lag: In traditional steel plate warehouses, information transmission mainly relies on manual methods, such as verbal communication and paper documents. From the receipt of steel plates and changes in storage location to their issuance, the transmission of information between different personnel takes time and is prone to omissions or errors. For example, when a batch of steel plates needs to be transferred from area A to area B, if the information transmission is not timely or accurate, it may cause staff to search for steel plates in the wrong location, wasting time.

[0008] Reliance on individual experience and skills: Manual dispatching relies excessively on the individual experience and skills of warehouse managers, and different personnel vary in work efficiency and accuracy. Experienced employees may be able to locate and dispatch the required steel plates quickly, but new employees may need a longer time to familiarize themselves with the workflow and warehouse layout, which to some extent affects the overall dispatching efficiency.

[0009] 3. Stacking methods result in a high rate of steel plate damage.

[0010] Improper handling: Without strict operating procedures and training, workers may stack steel plates haphazardly, leading to increased collisions and friction between the plates and causing surface damage. For example, placing heavier steel plates on lighter ones, or not aligning the edges of the plates during stacking, can cause the lower plates to be squeezed or scratched.

[0011] Inappropriate equipment: Using unsuitable stacking equipment can also increase the risk of surface damage to steel plates. Some simple lifting equipment or forklifts may not have sufficient precision and stability, and may cause shaking or tilting when lifting and stacking steel plates, resulting in relative movement between the plates and thus surface damage.

[0012] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology, facilitating the safe storage and scheduling of steel plates of different specifications. Utility Model Content

[0013] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a flexible intelligent stacking warehouse device for steel plates, which is suitable for efficient storage and intelligent scheduling of steel plates of different specifications.

[0014] To achieve the above objectives, this utility model provides the following technical solution:

[0015] A flexible intelligent steel plate stacking device includes a truss lifting structure, a steel plate storage warehouse, a plate carrier, a control system, and a flexible intelligent gripping device suspended on a Z-axis crane. The flexible intelligent gripping device is used to grip the steel plates. The truss lifting structure includes two longitudinal guide rails erected in the air and a truss crane that slides along the longitudinal guide rails. The truss crane includes a crossbeam guide rail that travels along the longitudinal guide rails and a Z-axis crane mounted on the crossbeam guide rail. The Z-axis crane is equipped with a weight detection module for monitoring the lifting load, and the crossbeam guide rail is equipped with a 3D vision sensor for identifying the length and width of the steel plates.

[0016] The steel plate storage warehouse includes a main frame, which is divided into a stacking area and a transfer area along the horizontal direction. At least the transfer area is within the movement range of the flexible intelligent clamping and lifting device. The stacking area is provided with several storage unit layers along the vertical direction. The transfer area is provided with a steel plate transfer mechanism for lifting, lowering and translating the plate carrier.

[0017] The control system is used to record the specifications of the steel plates stored in each storage unit layer, and to match the steel plate specifications based on the steel plate size obtained by the 3D vision sensor and the steel plate weight obtained by the weight detection module, and to control the operation of the steel plate transfer mechanism and the plate carrier to store the transported steel plates into the corresponding specification storage unit layer.

[0018] Furthermore, the storage unit layer is provided with a steel plate inlet and outlet only on the side facing the transfer area, and the other sides of the storage unit layer are limited and blocked by the main column to prevent the steel plate from accidentally sliding out.

[0019] Furthermore, the steel plate transfer mechanism includes a lifting mechanism disposed at both ends of the main frame and a transverse mechanism disposed on the lifting mechanism; the lifting mechanism is used to lift the transported steel plate to the height corresponding to the storage unit layer of the corresponding specification, and then the plate carrier is moved horizontally into the storage unit layer.

[0020] In one specific embodiment, the lifting mechanism includes a lifting platform and at least two lifting screws rotatably mounted on the longitudinal end of the main frame, the longitudinal ends of the lifting platform being threadedly engaged with the lifting screws; the transverse mechanism is mounted on the lifting platform, the transverse mechanism includes a reciprocating transverse chain, and a lever is provided on the outer periphery of the transverse chain; a hook that engages with the lever is provided on one long side of the carrier frame.

[0021] Furthermore, each storage unit layer is equipped with an external lateral movement mechanism for assisting in the translation of the carrier plate frame.

[0022] Furthermore, the storage unit layer is formed by a shelf fixed to the main frame, and the outer transverse movement mechanism is arranged on the shelf. The outer transverse movement mechanism cooperates with the transverse movement mechanism to allow the carrier plate shelf to move into and out of the storage unit layer.

[0023] In one specific embodiment, the main frame includes several main columns, and the shelving includes tie beams connecting the columns and support beams connected to two opposing tie beams.

[0024] Furthermore, the flexible intelligent clamping lifting device includes a main crossbeam suspended on a Z-axis crane, telescopic crossbeams telescopically disposed at both ends of the main crossbeam, a power mechanism for driving the telescopic crossbeams to extend and retract, and electromagnetic lifting devices respectively installed on the main crossbeam and the telescopic crossbeams; the control system automatically adjusts the telescopic length of the telescopic crossbeams according to the length of the steel plate obtained by the 3D vision sensor.

[0025] Furthermore, a layer guide rail is provided inside the storage unit layer, and a guide block or guide wheel matching the layer guide rail is provided on the carrier plate frame. The layer guide rail cooperates with the guide block / guide wheel, so that the carrier plate frame can be moved horizontally into the storage unit layer without tilting.

[0026] Furthermore, one or more steel plate storage bins are provided below the longitudinal guide rail, and all steel plate storage bins are arranged longitudinally aligned.

[0027] The working principle of this utility model is to automatically allocate and determine the storage unit layer position where the steel plate should be stored based on the size information scanned by the 3D vision sensor and the weight information obtained by the weight detection module, and to direct the truss lifting structure to accurately transport the steel plate to the storage unit layer.

[0028] The beneficial effects of this utility model are:

[0029] This invention achieves precise identification of steel plate specifications by combining a flexible intelligent clamping and lifting device with a 3D vision sensor and a weight detection module. The combination of the 3D vision sensor and the flexible intelligent clamping and lifting device enables rapid and accurate identification and gripping of steel plates of different sizes, greatly improving the automation and efficiency of steel plate stacking. Furthermore, combining this with the steel plate weight obtained from the weight detection module allows for precise matching of steel plate specifications. The truss lifting structure can transport steel plates from a designated loading area to multiple steel plate storage warehouses, where a steel plate transfer mechanism stores the steel plates into or retrieves them from the corresponding storage unit layer, improving the overall operational efficiency and accuracy of the steel plate stacking warehouse.

[0030] The control system automatically matches and directs the steel plate transfer mechanism and the carrier rack based on the acquired steel plate information, realizing intelligent inventory management and material handling, reducing manual intervention and lowering labor costs.

Detailed Implementation

[0039] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art are within the protection scope of this utility model.

They are used only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected" and "linked" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0041] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0042] like Figures 1 to 6As shown, a flexible intelligent steel plate stacking device includes a truss lifting structure 200, a steel plate storage warehouse 100, a plate carrier frame 130, a control system, and a flexible intelligent gripping device 400 suspended on a Z-axis crane. The flexible intelligent gripping device 400 is used to grip steel plates. The truss lifting structure 200 includes several truss columns 210, two longitudinal guide rails 220 erected opposite to each other at the top of the truss columns 210, and a truss crane 300 sliding along the longitudinal guide rails 220. The truss crane 300 includes a crossbeam guide rail 230 that travels along the longitudinal guide rails 220 and a Z-axis crane mounted on the crossbeam guide rail 230. The Z-axis crane is equipped with a weight detection module for monitoring the lifting load, and the crossbeam guide rail 230 is equipped with a 3D vision sensor 240 for identifying the length and width of the steel plate.

[0043] The steel plate storage warehouse 100 includes a main frame, which is divided into a stacking area and a transfer area along the horizontal direction. At least the transfer area is within the movement range of the flexible intelligent clamping and lifting device 400. The stacking area is provided with several storage unit layers along the vertical direction. Each storage unit layer is provided with an external horizontal movement mechanism for assisting in the translation of the plate carrier 130. The transfer area is provided with a steel plate transfer mechanism for lifting, lowering, and translating the plate carrier 130.

[0044] The control system is used to record the specifications of the steel plates stored in each storage unit layer, and to match the steel plate specifications according to the steel plate size obtained by the 3D vision sensor 240 and the steel plate weight obtained by the weight detection module, and to control the operation of the steel plate transfer mechanism and the plate carrier 130 to store the transported steel plates into the storage unit layer of the corresponding specifications.

[0045] The 3D vision sensor 240 boasts high resolution, achieving an acquisition accuracy of 0.1mm. It can acquire a large number of 3D data points in a short time, enabling rapid scanning and measurement of objects. Suitable for online inspection, it represents a mature and readily available technology. The weight detection module requires a measuring range of 0-10t and an accuracy of 0.5%. This level of precision ensures the accuracy and reliability of the measurement results.

[0046] like Figures 1 to 4As shown, the main frame adopts a multi-layer steel structure, which has high strength and stability and can withstand the weight of a large number of steel plates. The main frame includes several main columns 110, and the storage unit layers are formed by shelves 112 fixed to the main frame. The external lateral movement mechanism is set on the shelves 112. The shelves 112 include tie beams connecting the columns and support beams connecting two opposite tie beams. The columns are the vertical support components of the entire frame, and their materials and specifications are designed and selected according to factors such as the height of the storage warehouse and the expected load-bearing weight. The tie beams connect the columns and enhance the overall rigidity of the frame. They are connected to the columns by welding or high-strength bolts to ensure that the frame does not deform under load. The support beam serves as the installation foundation for structures such as the layer guide rails, providing support and guidance for the trolley's movement. The support beam typically has a specific cross-sectional shape and size to ensure sufficient load-bearing capacity and stability, allowing the trolley to move smoothly on it. The carrier frame 130 is equipped with guide blocks or guide wheels 133 that match the layer guide rails. The layer guide rails cooperate with the guide blocks / guide wheels 133, allowing the carrier frame 130 to move horizontally into the storage unit layer without tilting. In this embodiment, as... Figures 1 to 4 As shown, conventional triangular guide rails can be used for the layer guide rails. Triangular guide rails have high stability, load-bearing capacity and guiding accuracy. They are used in conjunction with guide wheels 133. Guide wheels 133 are at least set at both ends of the carrier frame 130, and several rows of guide wheels 133 can also be set in the middle of the carrier frame 130.

[0047] Furthermore, such as Figures 1 to 4 As shown, the storage unit layer has a steel plate entrance and exit only on the side facing the transfer area. The other sides of the storage unit layer are limited and blocked by the main column 110 to prevent the steel plate from sliding out accidentally and to ensure that there are no safety hazards on site.

[0048] Furthermore, such as Figures 1 to 4 As shown, one or more steel plate storage bins 100 are provided below the longitudinal guide rail 220. All steel plate storage bins 100 are arranged longitudinally aligned, so that one truss lifting structure 200 can be used for multiple steel plate storage bins 100.

[0049] like Figures 1 to 4 As shown, the steel plate transfer mechanism includes a lifting mechanism located at both longitudinal ends of the main frame and a lateral movement mechanism mounted on the lifting mechanism. The lifting device is a key piece of equipment for vertically transporting steel plates and can be a hydraulic lifting mechanism, a chain lifting mechanism, a screw lifting mechanism, a scissor lifting mechanism, etc. The lifting mechanism is used to lift the arrived steel plates to the height corresponding to the storage unit layer of the corresponding specification, and then the plate carrier 130 is moved horizontally into the storage unit layer.

[0050] In a specific example, such as Figures 1 to 4As shown, the lifting mechanism includes a lifting platform 121 and at least two lifting screws 120 rotatably mounted on the longitudinal end of the main frame. The longitudinal ends of the lifting platform 121 are threadedly engaged with the lifting screws 120. The screw-type lifting mechanism transmits power to the lifting platform 121 through a motor drive, causing the platform to move up and down along the screw guide rail. The lifting devices all have the characteristics of fast lifting speed, stable operation, and strong load-bearing capacity, which can meet the vertical transportation needs of steel plates of different weights.

[0051] like Figures 1 to 4 As shown, the traverse mechanism is mounted on the lifting platform 121. The traverse mechanism includes a reciprocating traverse chain with a lever on its outer periphery. A hook 134 cooperating with the lever is provided on one long side of the carrier frame 130. Specifically, a traverse motor and a main sprocket are mounted on the outside of the lifting platform, and a secondary sprocket is rotatably mounted on the inside of the lifting platform. The traverse chain is mounted on the main and secondary sprockets. The traverse motor drives the sprocket to rotate through a transmission structure, thereby causing the traverse chain to rotate forward or backward. When the traverse chain rotates forward, the lever pushes the hook and carrier frame 130 towards the storage unit layer; when the traverse chain rotates backward, the hook can engage with the lever, pulling the carrier frame 130 out of the storage unit layer.

[0052] In the above embodiment, the carrier frame 130 is unpowered. In another embodiment, the carrier frame 130 is equipped with wheels and a power assembly (the power assembly includes a motor, a reducer, and other components). The motor of the carrier frame 130 provides power, and the reducer reduces the speed and increases the torque to drive the wheels to rotate, so that the carrier frame 130 can move on the layer guide rail.

[0053] The number and size of the pallet racks 130 are designed based on factors such as the number of layers in the storage warehouse, the number of steel plates that can be stored on each layer, and the size of the steel plates, to ensure efficient handling of steel plates between different layers; alternatively, pallet racks 130 of uniform size can be designed. The pallet racks 130 can also be equipped with an XY two-dimensional guide rail system for lateral or longitudinal translation of steel plates placed on the pallet racks 130 from a designated loading area. The XY two-dimensional guide rail system can be automatically or manually controlled; existing XY two-dimensional guide rail systems can be used.

[0054] like Figures 1 to 2 , Figure 5 , Figure 6As shown, the truss lifting structure 200 can be a truss crane that meets the requirements of this utility model in the prior art, with a 3D vision sensor 240 installed on its crossbeam guide rail 230. Steel plates transported by other transfer equipment are loaded after stopping at the designated loading area, and the 3D vision sensor 240 identifies the size of the steel plates in the designated loading area. The flexible intelligent clamping lifting device 400 includes a main crossbeam 420 suspended on a Z-axis crane, telescopic crossbeams 430 telescopically arranged at both ends of the main crossbeam 420, a power mechanism for driving the telescopic crossbeams 430 to extend and retract, and electromagnetic lifting devices 440 respectively installed on the main crossbeam 420 and the telescopic crossbeams 430; the main crossbeam 420 is provided with 4 to 8 lifting rings 410; the control system automatically adjusts the extension length of the telescopic crossbeams 430 according to the length of the steel plate obtained by the 3D vision sensor 240. The flexible intelligent clamping lifting device 400 uses a magnetic chuck lifting device for lifting steel plates with a telescopic beam in the prior art, and is connected to the control system for automatic control.

[0055] The working process of this utility model is as follows: The operator transports the steel plate to be stored to the designated loading area. After the device is started, the 3D vision sensor immediately scans the steel plate, obtains its size information, and transmits it to the control system. Based on the length information of the steel plate, the control system automatically controls the extension and retraction length of the flexible lifting device's clamping end to fit the length of the steel plate perfectly. Subsequently, the truss crane lowers the flexible lifting device to a suitable position to contact the steel plate (with a landing detection device). At the same time, the landing detection device is activated. Once it is detected that the flexible intelligent clamping lifting device is in good contact with the steel plate, the magnetization program of the electromagnetic lifting device is started. After successful magnetization, the electromagnetic lifting device generates a strong suction force to firmly hold the steel plate, allowing it to be lifted. At this point, the control system, based on the previously scanned steel plate information, automatically determines the storage unit layer where the steel plate should be stored. The lifting platform moves to the same height as the storage unit layer corresponding to the steel plate's specifications, and the traverse motor drives the traverse chain to move the carrier rack from the storage unit layer onto the lifting platform. Then, the lifting platform, carrying the carrier rack, descends to its lowest position (the lowest position is the safest for loading steel plates). The flexible intelligent clamping lifting device places the steel plate on the carrier rack (during the lowering process, the XY two-dimensional guide rail system is adjusted to align the steel plate to be stored with the stack of steel plates already on the carrier rack as much as possible). The lifting platform then moves up to the position corresponding to the carrier rack that was just removed, and the traverse motor drives the traverse chain to move the carrier rack horizontally into the storage unit layer. Throughout the process, all mechanisms work together to efficiently complete the automatic storage and stacking of steel plates. Simultaneously, the control system records the storage location and time of each steel plate in real time, facilitating subsequent inventory management and retrieval.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
