Description

Technical Field

[0001] The present application relates to the field of metal smelting application technology, and in particular to a roller system control method and related equipment. Background Art

[0002] Currently, the transfer of slabs from the continuous casting process to the hot rolling furnace is a crucial step in the steel production process. Accurately identifying slab numbers is crucial for acquiring slab information, establishing secondary data models, and communicating with primary automation control. This is directly related to the smooth and efficient operation of the entire production process. With growing market demand in the steel industry, the overall production process is accelerating to improve production efficiency, and steelmaking loading speeds are also increasing accordingly. Currently, material codes are typically sprayed on the head of the slab for identification at a specific location on the roller conveyor in front of the furnace.

[0003] However, due to the accelerated pace of production, the use of pushers in the continuous casting process of steelmaking leaves little room between slabs. When these slabs are transported to the hot rolling area's rollers for slab number identification, the preceding slab often obscures the material number of the following slab. This prevents complete slab number identification, hindering subsequent data communication and control. To address this issue, operators currently rely on manual, repetitive control of a single roller set. Operators must manually set and reset roller data, combined with manual control of the individual roller sets, to position and separate slabs until the next slab number can be detected. However, this manual intervention approach has several drawbacks. First, the frequent manual operation places a significant workload on operators. Second, frequent human intervention directly reduces production efficiency. Finally, the frequent forward and reverse rotation of the roller motors and the frequent starting and stopping of the inverters significantly impact the equipment's service life. Therefore, it is necessary to propose a roller system control method that can at least partially address these issues. Summary of the Invention

[0039] In order to better understand the technical solutions provided by the embodiments of this specification, the technical solutions of the embodiments of this specification are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

The term "two or more" includes two or more than two cases.

[0041] See also Figure 1 , is a flow chart of a roller conveyor system control method provided in an embodiment of the present application, wherein the roller conveyor system includes a first roller conveyor group and a second roller conveyor group adjacently arranged along a target direction, wherein the first roller conveyor group and the second roller conveyor group are configured to transport a first slab and a second slab along the target direction, and specifically may include:

[0042] S110. During the process of the first roller conveyor group transporting the adjacent first and second slabs, if a target signal indicating that the head of the first slab enters the second roller conveyor group is detected, the second roller conveyor group is controlled to operate, and an overlap length ratio of the first slab in the second roller conveyor group is obtained, where the overlap length ratio is the ratio of the length of the first slab entering the second roller conveyor group in the target direction to the total length of the first slab, and the overlap length ratio is less than or equal to 1.

[0043] For example, Figure 2 As shown in FIG. 1 , a schematic diagram of slab operation in a roller system control method proposed in this application is shown in FIG. Figure 3The figure shows a schematic diagram of the structure for completing slab separation in a roller system control method proposed in the present application. In actual application, the roller system is composed of a first roller group and a second roller group arranged adjacent to each other along the target direction, and its main function is to transport the first slab and the second slab along the target direction. When the first roller group transports the adjacent first and second slabs, the system will continuously monitor whether there is a target signal that the head of the first slab enters the second roller group. This target signal is obtained by a grating installed at the starting position of the second roller group. When the head of the first slab passes the position of the grating, the grating will detect the obstruction of the object and thus send out a target signal. Among them, the head of the first slab is the frontmost position when it is transported from the first roller group to the second roller group. Once the roller system receives the target signal, it will immediately control the operation of the second roller group, so that the rollers of the second roller group start to rotate and prepare for receiving the first slab. After the first slab enters the second roller group, the overlap length ratio of the first slab in the second roller group is obtained, wherein the overlap length ratio is the ratio between the length of the first slab entering the second roller group and the total length of the first slab in the above-mentioned target direction, and the overlap length ratio is less than or equal to 1.

[0044] This system achieves automated connection of the roller conveyor system. Automatic detection and response avoids delays or errors that could result from manual operation, ensuring a smooth and seamless transition of the first slab from the first to the second roller conveyor set, improving the continuity and efficiency of slab transportation. This system also enhances real-time performance and accuracy. Sensors can promptly and accurately detect the position of the slab's head, enabling the second roller conveyor set to activate at the appropriate time, reducing the risk of slab jamming or collision at the roller conveyor junction.

[0045] S120: If the overlap length ratio reaches a preset length ratio threshold, control the first roller set to stop running to separate the first slab and the second slab.

[0046] Exemplarily, when the overlap length ratio of the first slab on the second roller group reaches a preset length ratio threshold, wherein the preset length ratio threshold in this application is 60%-70% of the length of the first slab, the roller system will generate a roller control instruction. These roller control instructions will be sent to the inverters that control adjacent rollers, such as inverter No. 2 and inverter No. 3, and the start and stop timing of the adjacent rollers will be controlled by controlling the operating status of the inverters. For example, when 60%-70% of the length of the first slab occupies the second roller group, the roller system will issue a roller control instruction to allow the second roller group to continue operating, while the first roller group stops operating, thereby realizing the automatic separation and transmission of the first slab and the second slab. After the first slab leaves the second roller group, the second slab begins to re-execute the above steps, and so on.

[0047] This system automatically separates the slabs, preventing the obstruction of the material code on the second slab due to insufficient space between the first and second slabs. This improves production efficiency. It eliminates manual intervention in the separation process, reducing labor costs and operation time, while also lowering the risk of inaccurate separation or errors caused by human factors. It ensures safe and stable slab transportation. By precisely controlling the stopping timing of the first roller group, it prevents collisions and squeezing between slabs, reduces the possibility of slab damage, and improves product quality and equipment life.

[0048] In summary, the roller system control method proposed in the embodiment of the present application detects that the head of a slab enters the second roller group during the process of the first roller group transporting the adjacent first and second slabs, and controls the second roller group to operate. At this time, the first roller group and the second roller group are both in operation. When the first slab has not yet completely entered the second roller group or has just entered the second roller group, the second slab has not yet entered the second roller group. The first roller group is controlled to stop operating, and the second slab will remain in the first roller group. At this time, the second roller group is continuously operating, so the first slab will continue to be transported forward in the target direction, thereby achieving the separation of the first slab and the second slab. Then, in the case where material codes are set on both the first slab and the second slab, by separating the two slabs, the problem of blocking the material code of the second slab due to insufficient space reserved between the first slab and the second slab can be avoided.

[0049] In some examples, the first slab is provided with a material code, and before controlling the operation of the second roller set, the method further includes:

[0050] controlling the first roller group to stop running within a preset time period, obtaining a material code of the first slab after the preset time period, and obtaining slab information of the first slab according to the material code;

[0051] The total length of the first slab is determined according to the slab information, and the target length of the first slab entering the second roller set is determined according to the total length and a length ratio threshold.

[0052] Exemplarily, a material code is assigned to the first slab, which controls the first roller group to stop within a preset duration, where the preset duration is 2 seconds. After the preset duration, the material code of the first slab is retrieved. The extracted material code is then matched against a pre-established slab database to retrieve the slab information corresponding to the material code, including detailed information such as the slab's length, specifications, and intended use. The total length of the first slab is determined based on the matched slab information. The target length of the first slab before entering the second roller group is determined based on the total length and a length ratio threshold. In this application, the preset length ratio threshold is 60%-70% of the first slab's length.

[0053] By automatically acquiring material codes and matching them with the database, slab material verification is automated, reducing manual workload and errors, improving production efficiency and data accuracy. Accurate slab information provides a crucial basis for calculating the target length of the first slab on the second roller group and achieving slab separation.

[0054] In some examples, the roller system further includes an image sensor, and obtaining the material code of the first slab after the preset time period includes:

[0055] After the preset time period, controlling the image sensor to collect image data of the first slab head;

[0056] The image data is processed based on image recognition technology to obtain a material code of the first slab.

[0057] Exemplarily, after the preset time, the roller system will generate a photo-taking instruction to control the image sensor to collect the image data of the head of the first slab, wherein the image sensor is camera 2, specifically: triggering camera 2 to take a photo of the head of the first slab. After camera 2 captures the image data of the first slab, it transmits it to the data center (PLC). The data center will process the acquired image data through an image recognition algorithm to extract the material code information of the slab. The application of image recognition technology improves the degree of automation of information acquisition and reduces the workload and errors of manual identification. At the same time, the setting of the preset delay time can ensure that the slab is photographed in a stable state, thereby improving the success rate of image recognition. The setting of the preset time length can avoid blurred photos caused by the fact that the first slab has not completely stopped, thereby improving the success rate and accuracy of material code acquisition.

[0058] In some examples, the roller system further includes a laser rangefinder 1, and controlling the first roller group to stop running within a preset time period includes:

[0059] controlling the laser rangefinder 1 to detect the head position of the first slab;

[0060] When the head position of the first slab reaches a preset stop position, the first roller set is controlled to stop running.

[0061] Exemplarily, a laser rangefinder 1 is used to detect the position of the head of the first slab. The laser rangefinder 1 continuously emits a laser beam to illuminate a specific position. In this application, the laser point is fixed on the second roller group at a distance of 15m. When the head of the slab moves to the laser irradiation area, the laser rangefinder 1 detects the reflected light and converts it into an electrical signal or a digital signal to determine the real-time position of the head of the slab. After receiving this real-time position signal, the control system will control the roller inverter, such as inverter No. 2 on the first roller group, to stop the roller from rotating according to the real-time position signal, thereby stopping the operation of the first slab.

[0062] The laser rangefinder 1 can accurately detect the position of the first slab head, ensuring that the first slab stops at the correct position. This precise position control provides a guarantee for subsequent material code acquisition and slab separation operations, improving the operating accuracy and reliability of the entire system.

[0063] In some examples, the roller system further includes a frequency converter, and if a target signal indicating that the head of the first slab enters the second roller group is detected, the second roller group is controlled to operate, including:

[0064] The inverter is controlled to operate the second roller table group based on the target signal.

[0065] For example, the roller system includes a frequency converter (VFD). Upon detecting a target signal indicating that the head of the first slab has entered the second roller group, the VFD controls the second roller group to operate based on this target signal. By controlling the rollers through the VFD, precise adjustment of roller speed is achieved. Prompt activation of the second roller group based on the target signal ensures continuous and coordinated slab transport, improving production efficiency. Furthermore, the VFD allows for flexible adjustment of roller operating parameters based on actual needs, reducing energy consumption.

[0066] In some examples, obtaining the overlap length ratio of the first slab in the second roller set includes:

[0067] Calculate the overlap length of the first slab after it enters the second roller set based on the roller circumference, the rotation speed, and the duration of time after the first slab enters the second roller set;

[0068] The overlap length ratio is obtained according to the ratio between the overlap length and the total length.

[0069] For example, the overlap length of the first slab after entering the second roller set is calculated based on the roller circumference and rotational speed of the second roller set and the duration of time the first slab has entered the second roller set. The overlap length calculated is divided by the total length of the first slab to obtain the overlap length ratio.

[0070] This calculation method accurately determines the overlap length ratio of the first slab in the second roller set. This provides accurate data for determining whether the preset length ratio threshold has been reached, ensuring that the first roller set stops at the appropriate time to achieve precise separation of the slabs.

[0071] In some examples, the roller system further includes a grating, and the duration of time after the first slab enters the second roller group is obtained by the following steps:

[0072] When a detection signal of the grating on the head of the first slab is received, the time when the detection signal is received is used as the starting time of the duration.

[0073] Exemplarily, the roller system further includes a grating, which includes a grating transmitting end 3 and a grating receiving end 4. When the head of a slab enters the second roller group, it blocks the light beam emitted by the grating transmitting end 3, causing the signal at the receiving end to be interrupted. The roller system immediately generates a detection signal. After the grating is triggered, the moment the detection signal is received is used as the starting moment of the duration, and timing begins at this moment.

[0074] By using the grating's detection signal to determine the start time of the duration, the time when the first slab enters the second roller set can be accurately recorded. This provides an accurate time parameter for subsequent calculation of the overlap length, further improving the accuracy of the overlap length ratio calculation, thereby ensuring the precision of slab separation control.

[0075] like Figure 3 As shown, this application proposes a roller system control system, the system includes: a data calculation module 21 and a data comparison module 22;

[0076] The data calculation module 21 is configured to: during the process of the first roller group transporting the adjacent first slab and the second slab, if a target signal is detected that the head of the first slab enters the second roller group, control the second roller group to operate, and obtain an overlap length ratio of the first slab in the second roller group, wherein the overlap length ratio is a ratio of a length of the first slab entering the second roller group in the target direction to a total length of the first slab, and the overlap length ratio is less than or equal to 1;

[0077] The data comparison module 22 is configured to control the first roller set to stop running if the overlap length ratio reaches a preset length ratio threshold, so as to separate the first slab and the second slab.
