Description

Technical Field

[0001] This invention relates to the field of port transportation technology, and in particular to a method for regulating the unmanned material handling flow in bulk cargo ports. Background Technology

[0002] Bulk cargo ports are ports specifically designed to handle unpackaged bulk cargoes such as coal, grain, sand, and iron ore. These cargoes are typically loaded and unloaded using large machinery such as grab cranes, conveyor belts, and reclaimers. Flow control at bulk cargo ports involves maintaining a stable or predetermined flow rate by controlling the speed and quantity of material handled. This is crucial for ensuring smooth production line operation and product quality. However, existing bulk cargo handling systems may have significant errors in flow control, leading to material waste or production line imbalances and impacting overall logistics efficiency. Furthermore, existing systems rely heavily on manual operation, which not only increases labor costs but may also introduce instability due to human factors. The operation of large machinery at bulk cargo ports also poses certain safety risks, especially for operators. Summary of the Invention

[0003] One object of the present invention is to solve at least the above-mentioned problems and / or defects, and to provide at least the advantages described below.

[0004] One objective of this invention is to provide a method for regulating the unmanned material handling flow rate at bulk cargo ports, which can realize the automatic regulation of the material handling flow rate at bulk cargo ports without relying on manual labor, thereby improving the accuracy and efficiency of material handling flow rate control.

[0005] To achieve these objectives and other advantages according to the present invention, a method for regulating unmanned material handling flow at a bulk cargo port is provided, comprising:

[0006] Step 1: Arrange material handling equipment at the bulk cargo port. The material handling equipment includes a material handling mechanism, a conveying mechanism, and a unloading mechanism. The conveying mechanism is located between the material handling mechanism and the unloading mechanism. A first pressure sensor is arranged in the material handling mechanism, and a second pressure sensor and a third pressure sensor are arranged at the starting point and the ending point of the conveying mechanism, respectively.

[0007] Step 2: Extract materials from the storage facility at the bulk cargo port using the material handling equipment and transfer the materials to the material receiving equipment. The specific process includes: controlling the material handling mechanism to extract materials from the storage facility in batches; detecting a first pressure value of the material handling mechanism using a first pressure sensor; determining a first weight value of the material extracted in the current batch based on the first pressure value; detecting a second pressure value at the starting position of the conveying mechanism using a second pressure sensor; determining a second weight value of the material carried at the starting position of the conveying mechanism based on the second pressure value; if the second weight value is greater than 0, controlling the material handling mechanism to pause transferring the material extracted in the current batch to the starting position of the conveying mechanism until the second weight value decreases to 0; and then controlling the material handling mechanism to transfer the material extracted in the current batch... The material is transferred to the starting point of the conveying mechanism, causing the second weight value to rise to match the first weight value. The material-retrieving mechanism is then controlled to return to the storage facility to retrieve the next batch of material. The conveying mechanism is controlled to continuously transport the received material to the unloading mechanism, and the unloading mechanism is controlled to transfer the received material to the material receiving device. The third pressure value at the end point of the conveying mechanism is detected by the third pressure sensor. Based on the third pressure value, the third weight value of the material carried at the end point of the conveying mechanism is determined. If the third weight value is greater than a set first weight limit, the unloading mechanism is controlled to increase the unloading speed of transferring the received material to the material receiving device until the third weight value drops below the first weight limit. The unloading mechanism then operates at the current unloading speed.

[0008] Preferably, in the unmanned material handling flow regulation method for bulk cargo ports, in step one, a fourth pressure sensor is installed in the unloading mechanism; in step two, the fourth pressure value of the unloading mechanism is detected by the fourth pressure sensor, and the fourth weight value of the material received by the unloading mechanism is determined based on the fourth pressure value. When the fourth weight value is less than a set lower weight limit, the conveying mechanism is controlled to increase the conveying speed of continuously conveying the received material to the unloading mechanism until the fourth weight value increases to above the lower weight limit, and the conveying mechanism operates at the current conveying speed.

[0009] Preferably, in the unmanned material handling flow regulation method for bulk cargo ports, in step two, when the fourth weight value is greater than a set second weight upper limit, the unloading mechanism is controlled to increase the unloading speed of transferring the received material to the material receiving equipment until the fourth weight value is reduced to below the second weight upper limit, and the unloading mechanism operates at the current unloading speed.

[0010] Preferably, in the unmanned material handling flow regulation method for bulk cargo ports, in step one, the material handling mechanism, the conveying mechanism, and the unloading mechanism are all communicatively connected to a remote control center; in step two, the first pressure value, the second pressure value, the third pressure value, the fourth pressure value, the first weight value, the second weight value, the third weight value, and the fourth weight value are all sent to the remote control center, and the working status of the material handling mechanism, the conveying mechanism, and the unloading mechanism is sent to the remote control center. The working status of the material handling mechanism includes extracting materials from the storage facility, transferring the materials extracted in the current batch to the starting point of the conveying mechanism, and pausing the transfer of the materials extracted in the current batch to the starting point of the conveying mechanism. The working status of the conveying mechanism includes continuously conveying the received materials to the unloading mechanism and the conveying speed at which the received materials are continuously conveyed to the unloading mechanism. The working status of the unloading mechanism includes transferring the received materials to the material receiving equipment and the unloading speed at which the received materials are transferred to the material receiving equipment.

[0011] Preferably, the unmanned material handling flow regulation method for bulk cargo ports further includes step three, which involves changing the working status of the material handling mechanism, the conveying mechanism, and the unloading mechanism through the remote control center.

[0012] Preferably, in the unmanned material handling flow regulation method for bulk cargo ports, in step three, when changing the working state of the material handling mechanism, the conveying mechanism, and the unloading mechanism through the remote control center, the working state of the material handling mechanism, the conveying mechanism, and the unloading mechanism is first switched to stop working, then the working state of the material handling mechanism, the conveying mechanism, and the unloading mechanism is reset, and then the material handling mechanism, the conveying mechanism, and the unloading mechanism are controlled to work according to the reset working state.

[0013] Preferably, in the unmanned material handling flow regulation method for bulk cargo ports, the material handling mechanism is a grab bucket, the conveying mechanism is a material handling conveyor belt, and the unloading mechanism is an unloading conveyor mechanism; the material receiving equipment includes a material transfer vehicle.

[0014] The present invention has at least the following beneficial effects:

[0015] This invention provides a method for regulating the unmanned material handling flow rate at a bulk cargo port, comprising: Step 1, arranging material handling equipment at the bulk cargo port, wherein the material handling equipment includes a material handling mechanism, a conveying mechanism, and a unloading mechanism, the conveying mechanism being disposed between the material handling mechanism and the unloading mechanism, a first pressure sensor being arranged at the material handling mechanism, and a second pressure sensor and a third pressure sensor being arranged at the starting point and ending point of the conveying mechanism, respectively; Step 2, extracting materials from the storage facility at the bulk cargo port using the material handling equipment and transferring the materials to a material receiving device, specifically including: controlling the material handling mechanism to extract materials from the storage facility in batches, detecting a first pressure value of the material handling mechanism using the first pressure sensor, determining a first weight value of the material extracted by the material handling mechanism in the current batch based on the first pressure value, detecting a second pressure value at the starting point of the conveying mechanism using the second pressure sensor, and determining a second weight value of the material carried at the starting point of the conveying mechanism based on the second pressure value, as in Step 2. If the weight value is greater than 0, the material handling mechanism is controlled to pause transferring the material extracted in the current batch to the starting point of the conveying mechanism until the second weight value decreases to 0. Then, the material handling mechanism is controlled to transfer the material extracted in the current batch to the starting point of the conveying mechanism, causing the second weight value to rise to match the first weight value. The material handling mechanism is then controlled to return to the storage facility to extract the next batch of material. The conveying mechanism is controlled to continuously convey the received material to the unloading mechanism. The unloading mechanism is controlled to transfer the received material to the material receiving device. The third pressure value at the end position of the conveying mechanism is detected by the third pressure sensor. The third weight value of the material carried at the end position of the conveying mechanism is determined based on the third pressure value. If the third weight value is greater than a set first weight limit, the unloading mechanism is controlled to increase the unloading speed of transferring the received material to the material receiving device until the third weight value decreases below the first weight limit. The unloading mechanism then operates at the current unloading speed. This invention improves the coordination among the three mechanisms by installing pressure sensors at the starting and ending points of the material handling and conveying mechanisms. This allows for the determination of material weight data in the material handling and conveying mechanisms based on the pressure data. Furthermore, it controls the material handling operation of the material handling mechanism and the unloading operation of the unloading mechanism based on the material weight data, thereby improving the coordination among them. This results in automatic adjustment of the material handling flow rate at bulk cargo ports, eliminating the need for manual control and ultimately improving the accuracy and efficiency of material handling flow rate control.

[0016] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0017] Figure 1 This is a block diagram of the unmanned material handling flow regulation system for bulk cargo ports provided in an embodiment of the present invention. Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0019] This invention provides a method for regulating the unmanned material handling flow rate at bulk cargo ports. This method can be implemented by an unmanned material handling flow rate regulation system for bulk cargo ports, the block diagram of which is shown below. Figure 1 As shown. The method includes: Step 1, arranging a material handling device at the bulk cargo port, wherein the material handling device includes a material handling mechanism, a conveying mechanism, and a unloading mechanism, the conveying mechanism being arranged between the material handling mechanism and the unloading mechanism, arranging a first pressure sensor at the material handling mechanism, and arranging a second pressure sensor and a third pressure sensor at the starting point and ending point of the conveying mechanism, respectively; Step 2, extracting materials from the storage facility at the bulk cargo port through the material handling device and transferring the materials to a material receiving device, specifically including: controlling the material handling mechanism to extract materials from the storage facility in batches, detecting a first pressure value of the material handling mechanism through the first pressure sensor, determining a first weight value of the material extracted by the material handling mechanism in the current batch based on the first pressure value, detecting a second pressure value at the starting position of the conveying mechanism through the second pressure sensor, determining a second weight value of the material carried at the starting position of the conveying mechanism based on the second pressure value, and if the second weight value is greater than 0, then controlling the material handling mechanism to extract materials from the storage facility in batches. The material handling mechanism pauses transferring the material extracted in the current batch to the starting point of the conveying mechanism until the second weight value decreases to 0. Then, the material handling mechanism is controlled to transfer the material extracted in the current batch to the starting point of the conveying mechanism, causing the second weight value to rise to match the first weight value. The material handling mechanism is then controlled to return to the storage facility to extract the next batch of material. The conveying mechanism is controlled to continuously transport the received material to the unloading mechanism. The unloading mechanism is controlled to transfer the received material to the material receiving device. A third pressure sensor detects the third pressure value at the end point of the conveying mechanism. Based on the third pressure value, the third weight value of the material carried at the end point of the conveying mechanism is determined. If the third weight value is greater than a set first weight limit, the unloading mechanism is controlled to increase the unloading speed of the received material transferred to the material receiving device until the third weight value decreases below the first weight limit. The unloading mechanism then operates at the current unloading speed.

[0020] Specifically, in the process of retrieving materials from the material handling equipment, the material handling mechanism retrieves materials from the storage facility in batches. In existing methods, the material handling speed of the material handling mechanism is generally constant; that is, after each material is retrieved, the material is immediately transferred to the conveying mechanism, and then transferred to the storage facility for further retrieval. However, this method does not consider the carrying capacity of the conveying mechanism and does not work in coordination with it, which can easily lead to material accumulation in the conveying mechanism. To solve the above problems, this invention sets a first pressure sensor in the material handling mechanism to detect a first pressure value, and a second pressure sensor at the starting point of the conveying mechanism to detect a second pressure value at the starting position of the conveying mechanism. Based on the first and second pressure values, the first weight value of the current batch of material retrieved by the material handling mechanism and the second weight value of the material carried at the starting position of the conveying mechanism can be determined, respectively. If the second weight value is greater than 0, it indicates that the conveying mechanism has not yet transported the material that the material handling mechanism previously transferred to the starting position of the conveying mechanism. If the material handling mechanism directly places the material onto the conveying mechanism at this time, it may cause the conveying mechanism to be overloaded or cause material accumulation in the conveying mechanism. Therefore, when the second weight value is greater than 0, the present invention controls the material-picking mechanism to enter a waiting mode, pausing the transfer of the current batch of material to the conveying mechanism until the conveying mechanism has transported the material at the starting position, causing the second weight value to decrease to 0. Then, the material-picking mechanism is controlled to transfer the current batch of material to the starting position of the conveying mechanism. When all the material in the material-picking mechanism has been transferred to the starting position of the conveying mechanism, the second weight value will rise to the same level as the first weight value, indicating that the material transfer is complete. The material-picking mechanism will then return to the storage facility to retrieve the next batch of material, while the conveying mechanism will continue to transport the material to the unloading mechanism.

[0021] In existing methods, the unloading speed of the unloading mechanism is constant. Regardless of the amount of material carried by the conveyor, the unloading mechanism takes material from the conveyor at a fixed speed and transfers it to the material receiving device. However, this method does not consider the carrying capacity of the conveyor and does not work in coordination with it, easily leading to material accumulation within the conveyor. To solve this problem, this invention installs a third pressure sensor at the end of the conveyor. This sensor detects a third weight value of the material carried at the end of the conveyor. If the third weight value is greater than a set first weight limit, the unloading mechanism is controlled to increase its unloading speed, accelerating the transfer of material from the conveyor to the material receiving device, until the third weight value is reduced below the first weight limit, allowing the unloading mechanism to operate at the current unloading speed.

[0022] Through the above process, this invention, by deploying pressure sensors at the starting and ending points of the material handling mechanism and the conveying mechanism, collects pressure data in real time, determines the material weight data in the material handling mechanism and the conveying mechanism based on the pressure data, and then controls the material handling operation of the material handling mechanism and the unloading operation of the unloading mechanism based on the material weight data in the material handling mechanism and the conveying mechanism, improves the coordination effect among the material handling mechanism, the conveying mechanism and the unloading mechanism, and thus realizes the automatic adjustment of the material handling flow in bulk cargo ports, eliminates manual control, and ultimately improves the accuracy and efficiency of material handling flow control.

[0023] In a preferred embodiment, in the unmanned material handling flow regulation method for bulk cargo ports, in step one, a fourth pressure sensor is installed on the unloading mechanism; in step two, the fourth pressure value of the unloading mechanism is detected by the fourth pressure sensor, and the fourth weight value of the material received by the unloading mechanism is determined based on the fourth pressure value. When the fourth weight value is less than a set lower weight limit, the conveying mechanism is controlled to increase the conveying speed of continuously conveying the received material to the unloading mechanism until the fourth weight value increases above the lower weight limit, and the conveying mechanism operates at the current conveying speed.

[0024] The present invention also includes a fourth pressure sensor in the unloading mechanism to detect a fourth pressure value of the unloading mechanism. Based on this fourth pressure value, a fourth weight value of the material received by the unloading mechanism can be determined. When the fourth weight value is less than a set lower weight limit, it indicates that the unloading mechanism is not operating sufficiently. In this case, the conveying mechanism is controlled to increase the conveying speed to improve the efficiency of transferring the material to the unloading mechanism.

[0025] In a preferred embodiment, in the unmanned material handling flow regulation method for bulk cargo ports, in step two, when the fourth weight value is greater than a set second weight upper limit, the unloading mechanism is controlled to increase the unloading speed of transferring the received material to the material receiving equipment until the fourth weight value is reduced to below the second weight upper limit, and the unloading mechanism operates at the current unloading speed.

[0026] Correspondingly, when the fourth weight value is greater than the second weight limit, it indicates that the unloading mechanism is at risk of overloading and the unloading speed needs to be improved. Therefore, the unloading mechanism should be controlled to increase its unloading speed.

[0027] A preliminary test can be conducted to determine the relationship between the first pressure value detected by the first pressure sensor and the first weight value of the material in the feeding mechanism. Then, during actual operation, the first weight value can be calculated based on the measured first pressure value and the relationship between the first pressure value and the first weight value. Similarly, the relationship between the second pressure value at the starting point of the conveying mechanism and the second weight value of the material carried at the starting point can be determined, and then the second weight value can be calculated based on the measured second pressure value during actual operation. Likewise, the relationships between the third pressure value at the ending point of the conveying mechanism and the third weight value carried at the ending point, and the fourth pressure value at the unloading mechanism and the fourth weight value of the material carried by the unloading mechanism, can be determined, and then the third weight value can be calculated based on the measured third pressure value, and the fourth weight value can be calculated based on the measured fourth pressure value during actual operation.

[0028] In a preferred embodiment, in the unmanned material handling flow regulation method for bulk cargo ports, in step one, the material handling mechanism, the conveying mechanism, and the unloading mechanism are all communicatively connected to a remote control center; in step two, the first pressure value, the second pressure value, the third pressure value, the fourth pressure value, the first weight value, the second weight value, the third weight value, and the fourth weight value are all sent to the remote control center, and the working status of the material handling mechanism, the conveying mechanism, and the unloading mechanism is sent to the remote control center. The working status of the material handling mechanism includes extracting materials from the storage facility, transferring the extracted materials of the current batch to the starting point of the conveying mechanism, and pausing the transfer of the extracted materials of the current batch to the starting point of the conveying mechanism. The working status of the conveying mechanism includes continuously conveying the received materials to the unloading mechanism and the conveying speed at which the received materials are continuously conveyed to the unloading mechanism. The working status of the unloading mechanism includes transferring the received materials to the material receiving equipment and the unloading speed at which the received materials are transferred to the material receiving equipment.

[0029] This invention allows for the control of the material handling mechanism, conveying mechanism, and unloading mechanism, as well as the calculation and processing of pressure and weight data. This can be accomplished by a control device installed within the material handling equipment, or by a remote control center. The control device can transmit various pressure and weight data, as well as the operating status parameters of the material handling, conveying, and unloading mechanisms, to the remote control center for unified monitoring.

[0030] In a preferred embodiment, the unmanned material handling flow regulation method for bulk cargo ports further includes step three, which involves changing the working status of the material handling mechanism, the conveying mechanism, and the unloading mechanism through the remote control center.

[0031] The controller can change the working status of the material handling mechanism, conveying mechanism and unloading mechanism through the remote control center. For example, the material handling speed of the material handling mechanism, the conveying speed of the conveying mechanism and the unloading speed of the unloading mechanism can be adjusted. Based on the automatic calculation of the control device, the effect of the coordinated work between the material handling mechanism, conveying mechanism and unloading mechanism can be improved.

[0032] In a preferred embodiment, in the unmanned material handling flow regulation method for bulk cargo ports, in step three, when changing the working state of the material handling mechanism, the conveying mechanism, and the unloading mechanism through the remote control center, the working state of the material handling mechanism, the conveying mechanism, and the unloading mechanism is first switched to stop working, then the working state of the material handling mechanism, the conveying mechanism, and the unloading mechanism is reset, and then the material handling mechanism, the conveying mechanism, and the unloading mechanism are controlled to work according to the reset working state.

[0033] When changing the working status of the material handling mechanism, conveying mechanism, and unloading mechanism through the remote control center, first switch the working status of the three to stop working, and then reset the working status of the three to ensure the safety and reliability of the material handling mechanism, conveying mechanism, and unloading mechanism, and avoid the safety hazards caused by the mismatch between the operation of the mechanism due to the switching of working status.

[0034] In a preferred embodiment, in the unmanned material handling flow regulation method for bulk cargo ports, the material handling mechanism is a grab bucket, the conveying mechanism is a material handling conveyor belt, and the unloading mechanism is an unloading conveyor mechanism; the material receiving equipment includes a material transfer vehicle.

[0035] In summary, this invention, by deploying pressure sensors at the starting and ending points of the material handling mechanism and the conveying mechanism, as well as the unloading mechanism, collects pressure data in real time. Based on the pressure data, it determines the material weight data in the material handling mechanism, the conveying mechanism, and the unloading mechanism. Then, based on the material weight data in the material handling mechanism, the material handling operation of the material handling mechanism, the unloading operation of the material handling mechanism, and the conveying operation of the conveying mechanism are controlled. This improves the coordination and cooperation among the three mechanisms, thereby achieving automatic adjustment of the material handling flow rate in bulk cargo ports, eliminating manual control, and ultimately improving the accuracy and efficiency of material handling flow rate control.

[0036] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for the present invention. Other modifications can be readily made by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and examples shown and described herein.
