[0007] The storage rack is used to store the steel strip output; the bridging iron plate is located between the punching press punching device and the storage rack, and is used to carry the steel strip output and isolate the steel strip output from the ground; the bridging iron plate is further used to determine the storage amount of the steel strip output stored in the storage rack, and generate a storage amount adjustment information when the storage amount of the steel strip output is greater than a first preset storage amount or the storage amount of the steel strip output is less than a second preset storage amount, and send the storage amount adjustment information to the controller module;

[0008] The controller module is used to adjust the operating speed of the punching press punching device and / or the rolling mill according to the storage amount of the steel strip output;

[0009] The rolling mill is used to obtain the steel strip output from the storage rack and perform rolling treatment on the steel strip output.

[0010] According to another aspect of the present invention, a steel strip feeding method is provided. The method includes: a punching press punching device, a bridging iron plate, a storage rack, a controller module, and a rolling mill;

[0011] Performing punching operation and / or punching work on the steel strip by the punching press punching device to obtain a steel strip output, and sending the operation output to the storage rack;

[0012] The steel strip output is stored through a storage rack; the bridging iron plate is located between the punching equipment of the punching press and the storage rack, and is used to carry the steel strip output and isolate the steel strip output from the ground; the bridging iron plate is also used to determine the storage quantity of the steel strip output stored in the storage rack, and when the storage quantity of the steel strip output is greater than a first preset storage quantity or less than a second preset storage quantity, generate storage quantity adjustment information and send the storage quantity adjustment information to the controller module;

[0024] Embodiment 1

[0025] Figure 1 This embodiment of the present invention provides a structural block diagram of a steel strip feeding system, and this embodiment is applicable to the situation where automatic steel strip feeding is required between a punching machine and a rolling mill. The steel strip feeding system can be implemented in the form of hardware and / or software, and the steel strip feeding system can be configured in an electronic device with data processing capabilities. As Figure 1 shown, the steel strip feeding system of this embodiment may include: a punching machine punching device 110, a storage rack 120, a controller module 130, a rolling mill 140, and a bridging iron plate 150. Among them:

[0026] The punching machine punching equipment 110 is used to perform punching operations and / or punching operations on the steel strip to obtain the steel strip output, and send the operation output to the storage rack.

[0027] Among them, the steel strip can be obtained by unwinding the steel coil. The steel coil is the steel strip after finish rolling and is wound into a steel strip by a coiler. The steel strip is unwound into a rectangle. When performing punching operations and / or punching operations on the steel strip, the punching operations and / or punching operations are carried out in the transmission direction corresponding to the long side of the steel strip. The material of the steel strip can be carbon structural steel, stainless steel, electrical steel, etc. The punching machine punching equipment is used to perform stamping processing on the steel strip and / or process the steel strip under power drive, and form holes with the required shape and size for production on the steel strip.

[0028] See Figure 2 , after the punching machine punching equipment 110 performs punching operations and / or punching operations on the steel strip, the generated steel strip output is directly connected to the storage rack 120.

[0029] The storage rack 120 is used to store the steel strip output; the bridging iron plate 150 is located between the punching machine punching equipment 110 and the storage rack 120, and is used to carry the steel strip output and isolate the steel strip output from the ground; the bridging iron plate 150 is also used to determine the storage volume of the steel strip output stored in the storage rack 120 and send the storage volume of the steel strip output to the controller module 130.

[0030] The bridging iron plate 150 is located between the punching machine punching equipment 110 and the storage rack 120, and is used to carry the steel strip output and isolate the steel strip output from the ground. The bridging iron plate 150 is directly connected to the punching machine punching equipment 110 and the storage rack 120, or is installed at the actual contact point between the steel strip output and the ground during storage.

[0031] By installing the bridging iron plate 150 between the punching machine punching equipment 110 and the storage rack 120, it is possible to avoid the direct contact between the steel strip output and the ground, thereby avoiding the friction between the steel strip output and the ground during transmission, and thus causing wear to the steel strip output.

[0032] See Figure 2 , during the process of the storage rack 120 storing the steel strip output, the storage rack 120 raises the steel strip output in direct contact with the storage rack 120 until the steel strip output in direct contact reaches the preset height, and stores the steel strip output between the punching machine punching equipment 110 and the storage rack 120, realizing the storage of as much steel strip output as possible without the punching machine punching equipment 110 stopping and without the need for position adjustment of the equipment in the overall system.

[0033] In addition, since the steel strip output can be transmitted to other devices through the storage rack 120, the storage rack 120 needs to be prevented from displacement due to the transmission of the steel strip output. Therefore, the storage rack 120 is fixed to the ground and does not displace during the transmission of the steel strip output.

[0034] Optionally, since the steel strip supporting plate 150 is used to carry the steel strip output and prevent the steel strip output from being isolated from the ground, in order to avoid abrasion of the steel strip output when the steel strip supporting plate 150 contacts the steel strip output, when constructing the steel strip supporting plate 150, the material hardness of the steel strip supporting plate 150 needs to be less than the material hardness of the steel strip output, and / or the roughness of the contact surface between the steel strip supporting plate 150 and the steel strip output is less than a preset roughness. The preset roughness is the minimum roughness when the steel strip supporting plate 150 and the steel strip output have relative displacement, causing abrasion to the steel strip output and the abrasion degree being greater than the preset degree. The preset degree is the maximum allowable abrasion of the preset steel strip output.

[0035] Optionally, since the steel strip output needs to be conveyed during the production process, in order to facilitate subsequent equipment to process the steel strip output, the steel strip supporting plate 150 is fixed between the ground or the punching machine 110 and the storage rack 120 and does not displace during the operation of the system.

[0036] Considering that when there is too much steel strip output stored between the punching machine 110 and the storage rack 120, the stored steel strip output will gradually approach the ground until it lands on the steel strip supporting plate 150 installed on the ground. The steel strip supporting plate 150 carries the steel strip output. And after the steel strip supporting plate 150 carries the steel strip output, as the storage quantity of the steel strip output increases, the quantity of the steel strip output carried by the steel strip supporting plate 150 will also increase. This causes friction between the steel strip outputs and / or between the steel strip output and the punching machine 110 and the storage rack 120, thereby wearing the stored steel strip output and affecting the quality of the generated products. Therefore, it is necessary to consider the storage quantity of the steel strip output stored between the punching machine 110 and the storage rack 120.

[0037] In this regard, the steel strip supporting plate 150 includes a sensor for determining the storage quantity of the steel strip output stored in the storage rack, and generating a storage quantity adjustment message and sending the storage quantity adjustment message to the controller module when the storage quantity of the steel strip output is greater than a first preset storage quantity or the storage quantity of the steel strip output is less than a second preset storage quantity.

[0038] The physical quantities collected by the sensor included in the steel strip supporting plate 150 include at least one of the following: the contact physical quantity between the steel strip supporting plate 150 and the steel strip output, the closest distance between the steel strip supporting plate 150 and the steel strip output.

[0039] Among them, the physical quantity of contact between the iron plate 150 and the steel strip output can be understood as the physical quantity that can be collected by the iron plate 150 using pre-installed sensors after the iron plate 150 comes into contact with the steel strip output, including at least one of the following: the position of the contact area between the iron plate 150 and the steel strip output on the iron plate 150, the contact area of the contact area between the iron plate 150 and the steel strip output, and the magnitude of the gravity borne by the iron plate 150 when bearing the steel strip output.

[0040] The closest distance between the iron plate 150 and the steel strip output can be understood as the iron plate 150 detecting the distance to the position of the steel strip output through an ultrasonic sensor and screening out the data with the smallest distance value from the returned distance data as the closest distance.

[0041] When the physical quantity collected by the sensor includes the pressure magnitude borne by the iron plate 150 when bearing the steel strip output:

[0042] Optionally, the iron plate 150 includes a weight sensor for detecting the weight of the steel strip output on the iron plate to obtain a weight detection result and determining the storage quantity of the steel strip output according to the weight detection result.

[0043] The weight sensor can be a device that converts the weight of the steel strip product into a measurable electrical signal and determines the weight of the steel strip product based on the measurable electrical signal. The weight sensor mainly works based on the strain principle and has an elastic body inside. When the weight of the steel strip product acts on the elastic body, the elastic body can deform. Strain gauges are pasted on the elastic body, and the strain gauges can change their resistance as the elastic body deforms. By measuring the change in the resistance of the strain gauges and using a circuit to convert it into an electrical signal proportional to the weight, such as a voltage or current signal, the measurement of the weight of the steel strip product is realized.

[0044] Based on the weight sensor installed on the iron plate 150, the gravity borne by the iron plate 150 is determined. According to the gravity borne by the iron plate 150 and the first table, the storage quantity of the steel strip output is determined. Among them, the first table is composed of at least one sample weight detection result, at least one sample storage quantity of the steel strip output, and the corresponding relationship between each sample weight detection result and the sample storage quantity of the steel strip output.

[0045] Among them, to ensure the accuracy of the first table, at least one sample test is carried out to determine the corresponding relationship between the storage quantity of different steel strip outputs and the weight detection results, and the first table is generated according to the corresponding relationship between the storage quantity of the steel strip output and the weight detection results, the weight detection results, and the sample storage quantity of the steel strip output. During the sample test process, the relative positions and models of the storage rack 120, the punching equipment 110 of the punching press, the iron plate 150, and the steel strip output are the same as those in the actual production operation.

[0046] Screen the sample weight detection results in the first table according to the weight detection results, obtain the sample weight detection results that are the same as the weight detection results, determine the storage volume of the sample steel strip output according to the sample weight detection results, and use the storage volume of the sample steel strip output as the storage volume of the steel strip output.

[0047] By determining the first table and determining the storage volume of the steel strip output according to the weight detection results and the first table, in the actual use process, the number of steel strips sent out can be quickly solved directly according to the weight detection results and the first table, providing sufficient calculation time for the controller 130 to adjust the operating speeds of the punching machine 110 and the rolling mill 140.

[0048] When the physical quantity collected by the sensor includes the closest distance between the iron plate 150 and the steel strip output:

[0049] Optionally, the iron plate includes an ultrasonic ranging sensor for detecting the storage distance of the steel strip output on the iron plate to obtain the storage distance, and determining the storage volume of the steel strip output according to the storage distance; the storage distance is the distance between the iron plate and the steel strip output above the iron plate; the ultrasonic ranging sensor determines the storage distance based on the ultrasonic propagation time; the ultrasonic propagation time is the time from when the ultrasonic ranging sensor emits ultrasonic waves to when it receives the steel strip reflection wave.

[0050] Among them, the storage rack 120 stores the steel strip output in a way of being lifted by the steel strip output. Therefore, the closer the steel strip output is to the ground, the more the number of the stored steel strip output, and the farther the steel strip output is from the ground, the fewer the number of the stored steel strip output. The iron plate 150 includes an ultrasonic ranging sensor for detecting the distance of the stored steel strip output, and determining the storage volume of the steel strip output according to the detected closest distance and the pre-generated second table. The second table is composed of at least one sample closest distance, at least one sample steel strip output storage volume, and the corresponding relationship between each sample closest distance and the sample steel strip output storage volume. To ensure the accuracy of the second table, at least one sample test is performed to determine the corresponding relationship between different sample steel strip output storage volumes and the sample closest distances, and the corresponding relationship, the sample steel strip output storage volume, and the sample closest distance are used to generate the second table.

[0051] By using the ultrasonic ranging sensor to detect the distance of the steel strip output on the iron plate to obtain the storage distance, and determining the storage volume of the steel strip output according to the storage distance, the number of the stored steel strip output can be determined before the stored steel strip output touches the iron plate 150, so that the controller module 130 can adjust the operating speeds of the punching machine 110 and the rolling mill 140 before the stored steel strip output touches the iron plate 150, providing sufficient calculation time for the calculation of the controller 130.

[0052] When the physical quantity collected by the sensor includes the contact area between the ironing plate 150 and the steel strip output, the contact area between the ironing plate 150 and the steel strip output is determined according to the sensor of the ironing plate 150, and the steel strip output storage amount corresponding to the contact area is determined according to the pre-generated third table. The third table is composed of at least one sample contact area, at least one sample steel strip output storage amount, and the corresponding relationship between the sample contact area and the sample steel strip output storage amount. The types of sensors for confirming the contact area between the ironing plate 150 and the steel strip output include at least one of the following: pressure-sensitive film, capacitive sensor, optical sensor, strain gauge sensor.

[0053] When the physical quantity collected by the sensor includes the position of the contact area between the ironing plate 150 and the steel strip output on the ironing plate 150, the position of the contact area between the ironing plate 150 and the steel strip output on the ironing plate 150 is determined, and the steel strip output storage amount corresponding to the position of the contact area between the ironing plate 150 and the steel strip output on the ironing plate 150 is determined according to the position of the contact area between the ironing plate 150 and the steel strip output on the ironing plate 150 and the pre-determined fourth table. The fourth table is composed of at least one sample position, at least one sample steel strip output storage amount, and the corresponding relationship between the sample position and the sample steel strip output storage amount.

[0054] Similarly, the determination method for the ironing plate 150 to determine that the steel strip output storage amount is less than the second preset storage amount.

[0055] The controller module 130 is used to adjust the operating speed of the punching equipment of the punching press and / or the rolling mill according to the storage amount adjustment information.

[0056] See Figure 3 , Figure 3 FIG. is the control circuit diagram of the steel strip feeding system applicable to the embodiment of the present invention; the controller module 130 communicates with the punching equipment 110 of the punching press, the rolling mill 140, and the ironing plate 150, receives the storage amount adjustment information sent by the ironing plate 150, and sends an operation control instruction to the punching equipment 110 of the punching press and the rolling mill 140 to control the operating speed of the punching equipment 110 of the punching press and the rolling mill 140. The controller module 130 can be a personal computer, a single-chip microcomputer, etc.

[0057] Based on obtaining the storage amount adjustment information of the ironing plate 150, the operating speed of the punching equipment 110 of the punching press and the rolling mill 140 is adjusted according to the operation control instruction. When the steel strip output storage amount is greater than the first preset quantity, the operating speed of the rolling mill is increased and the operating speed of the punching equipment of the punching press is decreased; when the steel strip output storage amount is less than the second preset quantity, the operating speed of the rolling mill is decreased and the operating speed of the punching equipment of the punching press is increased.

[0058] When the storage quantity of the steel strip output is greater than the first preset quantity, it indicates that the storage quantity of the steel strip output is excessive, and there may be a problem of mutual wear between the steel strip outputs due to the excessive storage quantity. At this time, the operating speed of the rolling mill will be increased and the operating speed of the punching equipment of the punching press will be reduced, so as to accelerate the consumption of the steel strip output, and then enable the storage quantity of the steel strip output to quickly return to between the first preset quantity and the second preset quantity.

[0059] When the storage quantity of the steel strip output is less than the second preset quantity, it indicates that the storage quantity of the steel strip output is too small, and there may be a problem that the rolling mill 140 rolls away the steel strip in the punching equipment 110 of the punching press. At this time, the operating speed of the rolling mill will be increased and the operating speed of the punching equipment of the punching press will be reduced, so as to accelerate the storage efficiency of the steel strip output, and then enable the storage quantity of the steel strip output to quickly return to between the first preset quantity and the second preset quantity.

[0060] The rolling mill 140 is used to obtain the steel strip output from the storage rack 120 and perform rolling processing on the steel strip output.

[0061] The rolling mill can be used to process the steel strip output into metal products of different shapes and sizes by rolling. During the rolling process of the rolling mill, through the rotation of two or more rolling rolls, the steel strip output is subjected to compression and friction forces between the rolling rolls, so as to undergo plastic deformation and realize the rolling of the steel strip output.

[0062] After the steel strip output is carried on the storage rack 120, the rolling mill 140 obtains the steel strip output from the storage rack 120 and performs rolling processing on the steel strip output according to the actual operation requirements.

[0063] The technical solution of this application uses a punching machine 110 to perform punching operations and / or perforating operations on a steel strip to obtain a steel strip output, and sends the operation output to a storage rack; the storage rack 120 stores the steel strip output, so that when the punching machine 110 and the rolling mill 140 are operating, when the operating speed of the rolling mill 140 is greater than that of the punching machine 110, the rolling mill 140 can still operate at the current operating speed without damaging the steel strip output or causing the steel strip output to break. By adjusting the operating speeds of the punching machine 110 and / or the rolling mill 140 through the controller module 130, when there is too much steel strip output, the operating speed of the punching machine 110 can be reduced and / or the operating speed of the rolling mill 140 can be increased, so as to avoid the storage rack 120 storing too much steel strip output when the operating speed of the punching machine 110 is greater than that of the rolling mill 140, resulting in mutual wear and extrusion between the steel strip outputs, and then damaging the transmission of the steel strip. Through the above operations, the automatic transmission of the steel strip output between the punching machine 110 and the rolling mill 140 can be realized, and the operating speeds of the punching machine 110 and the rolling mill 140 can be flexibly controlled by the controller during the transmission process, ensuring that the steel strip output will not be damaged or even broken due to the inconsistent operating speeds of the punching machine 110 and the rolling mill 140.

[0064] In an alternative embodiment, optionally, the controller module 130 is specifically configured to:

[0065] Determine the operating efficiency of the punching machine and the rolling mill;

[0066] Determine the adjustment quantity of the steel strip output according to the storage quantity of the steel strip output and a third preset quantity;

[0067] Adjust the operating efficiency of the punching machine and / or the rolling mill according to the operating efficiency of the punching machine and the rolling mill and the adjustment quantity of the steel strip output.

[0068] During the production process, avoid overly frequent and significant adjustments to the operating efficiency of the punching machine 110 and the rolling mill 140, so as not to affect the service life of the punching machine 110 and the rolling mill 140. When adjusting the operating efficiency of the punching machine and / or the rolling mill, determine the difference between the steel strip output storage quantity and the third preset quantity to obtain the steel strip output adjustment quantity, and determine the adjustment direction of the operating efficiency of the punching machine 110 and the rolling mill 140 according to the positive or negative sign of the difference between the steel strip output storage quantity and the third preset quantity. Then, adjust the operating efficiency of the punching machine and the rolling mill according to the magnitude of the steel strip output adjustment quantity and the adjustment direction of the operating efficiency of the punching machine 110 and the rolling mill 140, so that the quantity of the steel strip output stored in the storage rack 120 is at the third preset quantity. Thus, while not adjusting the operating efficiency of the punching machine and / or the rolling mill over a large range, the quantity of the steel strip output stored in the storage rack 120 is at the third preset quantity, thereby ensuring that the steel strip output is damaged as little as possible while reducing the life loss of the punching machine and / or the rolling mill.

[0069] In an alternative solution, optionally, the storage rack is fixed to the ground; the storage rack is configured with at least one roller; the rollers configured on the storage rack are used to carry the steel strip output and rotate in the transmission direction of the steel strip output when the steel strip output is being transmitted; when the steel strip output is transmitted between any two devices, no plastic deformation occurs.

[0070] Since the operation of the steel strip output mainly relies on the rolling mill 140 and the punching machine 110, when the steel strip output passes through the storage rack 120, to ensure the stability of the storage rack 120, the storage rack 120 needs to be fixed to the ground and ensure that there is no displacement. In addition, to reduce the friction between the steel strip output and the storage rack 120 and thus reduce the wear of the steel strip output, at least one roller can be configured on the storage rack 120, so that when the steel strip output is transmitted, the wear of the steel strip output can be reduced by using the rollers. And there is no displacement in the direction corresponding to the short side between any two adjacent devices of the steel strip output, which is to reduce the plastic deformation during the transmission of the steel strip output and thus affect the quality of the final product.

[0085] Optionally, determining the storage amount of the steel strip output according to the storage distance includes:

[0086] Determining a second table; the second table records at least one sample storage distance, at least one sample steel strip output storage amount, and the corresponding relationship between each sample storage distance and the sample steel strip output storage amount;

[0089] By adopting the technical solution of the present application, punching operations and / or punching operations are performed on the steel strip by the punching equipment 110 of the punching press to obtain the steel strip output, and the operation output is sent to the storage rack; and the storage rack 120 stores the steel strip output, so that when the punching equipment 110 of the punching press and the rolling mill 140 are operating, when the operating speed of the rolling mill 140 is greater than that of the punching equipment 110 of the punching press, the rolling mill 140 can still operate at the current operating speed, and no damage is caused to the steel strip output or the steel strip output does not break during operation. By adjusting the operating speeds of the punching equipment 110 of the punching press and / or the rolling mill 140 through the controller module 130, when the steel strip output is excessive, the operating speed of the punching equipment 110 of the punching press can be reduced and / or the operating speed of the rolling mill 140 can be increased, so as to avoid the situation that when the operating speed of the punching equipment 110 of the punching press is greater than that of the rolling mill 140, the storage rack 120 stores too much steel strip output, resulting in mutual wear and extrusion between the steel strip outputs, and further causing damage to the transmission of the steel strip. Through the above operations, the automatic transmission of the steel strip output between the punching equipment 110 of the punching press and the rolling mill 140 can be realized, and the operating speeds of the punching equipment 110 of the punching press and the rolling mill 140 can be flexibly controlled by the controller during the transmission process, ensuring that the steel strip output will not be damaged or even broken due to the inconsistent operating speeds of the punching equipment 110 of the punching press and the rolling mill 140.
