Description

Technical Field

[0001] This invention relates to the field of intelligent industrial manufacturing technology, specifically to an automatic material placement method, system, device, and medium for a crane garage. Background Technology

[0002] Currently, most glass factories use high-quality, qualified powder directly into the plant, ensuring that the composition, particle size, and moisture content of all incoming raw materials meet process requirements. Bulk quartz sand is typically stored in homogenization silos or crane garages for storage and dehydration to ensure the stability of the silica raw materials entering the kiln. Homogenization silos or crane garages are usually fed by bucket elevators or belt conveyors, and then uniformly removed by sand rakes or grab cranes, before being sent to the top of the raw material workshop silos via a screening system. Previously, traditional material distribution relied solely on manual, point-to-point unloading operations, entirely dependent on human factors and prone to uneven distribution. Furthermore, the feeding control method was only semi-automated, requiring workers to operate sand rakes or cranes for material removal. This manual operation resulted in low distribution efficiency, making it difficult to meet the demands of automated, high-efficiency material distribution. Summary of the Invention

[0003] In view of this, the present invention provides an automatic material placement method, system, device and medium for crane garages, to solve the problem that existing material placement methods can only rely on manual unloading operations at fixed points, which are completely affected by human factors, resulting in uneven material placement, seriously affecting material placement efficiency and making it difficult to achieve full automation of material placement.

[0004] In a first aspect, the present invention provides an automatic material placement method for a crane garage, the method comprising:

[0005] Determine the target storage area for the raw materials to be transferred, and during the process of driving the reversible distribution belt conveyor to the target storage area, obtain the first position of the unloading trolley and the second position of the reversible distribution belt conveyor in real time;

[0006] Based on the first and second positions, determine whether the unloading trolley and the reversible distribution belt conveyor are synchronized.

[0007] When the unloading trolley and the reversible distribution conveyor are out of sync, the speed of the unloading trolley is adjusted so that the unloading trolley and the reversible distribution conveyor are synchronized in real time. Then, synchronous unloading is started. At the same time, the raw materials to be transferred on the fabric conveyor are unloaded onto the reversible distribution conveyor via the unloading trolley for transfer. The reversible distribution conveyor is controlled to synchronously unload the raw materials to be transferred within the target storage area.

[0008] This invention first determines the target storage area for the raw materials to be transferred. During the operation of the reversible distribution conveyor belt towards the target storage area, the first position of the unloading trolley and the second position of the reversible distribution conveyor belt are acquired in real time. The synchronization of these two positions is then determined. If the unloading trolley and the reversible distribution conveyor belt are not synchronized, the speed of the unloading trolley is adjusted to synchronize them in real time. Synchronous unloading then begins, simultaneously unloading the raw materials to be transferred from the fabric conveyor belt onto the reversible distribution conveyor belt via the unloading trolley. The reversible distribution conveyor belt is controlled to synchronously unload the raw materials within the target storage area, achieving full automation of fabric distribution. This overcomes the reliance on manual fixed-point unloading in traditional fabric distribution, is completely unaffected by human factors and the environment, further avoids uneven fabric distribution, greatly improves fabric distribution efficiency, and meets the requirements for automatic and efficient fabric distribution.

[0009] In one optional implementation, the unloading trolley is speed-adjusted to synchronize its position with the reversible distribution belt conveyor in real time, including:

[0010] Calculate the positional deviation between the first and second positions;

[0011] The changes in positional deviation are determined, and the speed of the unloading trolley and the reversible distribution conveyor is adjusted accordingly based on these changes to ensure real-time synchronization between their positions. The changes in positional deviation include both gradual increases and gradual decreases. If the positional deviation gradually increases, the speed of the unloading trolley is reduced; if the positional deviation gradually decreases, the speed of the unloading trolley is increased.

[0012] This invention ensures that the unloading trolley and the reversible distribution belt conveyor maintain coordination during operation by tracking the positional deviation between them in real time and adjusting their respective speeds accordingly. This avoids material conveying interruptions, accumulation, or spillage caused by asynchronous positioning, greatly improving the continuity and efficiency of material distribution. It also helps reduce labor costs and the risk of operational errors, thus achieving highly efficient automated material distribution.

[0013] In one alternative implementation, determining the change in positional deviation includes:

[0014] The first running direction and first running speed of the unloading trolley corresponding to the current position, and the second running direction and second running speed of the reversible distribution belt conveyor are obtained respectively.

[0015] When the first running direction is the same as the second running direction, determine whether the first running speed is greater than the second running speed;

[0016] If the first operating speed is greater than the second operating speed, then the positional deviation is determined to gradually decrease;

[0017] If the first operating speed is less than the second operating speed, the positional deviation is determined to gradually increase.

[0018] This invention obtains the running speed and direction of the unloading trolley and the reversible distribution belt at their current positions, and determines the change in their positional deviation based on the running speed and direction. This allows for accurate determination of the change in the positional deviation between the unloading trolley and the reversible distribution belt, thereby improving the subsequent speed adjustment accuracy and helping to enhance the accuracy and reliability of material distribution.

[0019] In an optional implementation, when the first direction of travel is different from the second direction of travel, the automatic material placement method for the crane garage further includes:

[0020] If the unloading trolley and the reversible distribution belt conveyor move in opposite directions, the positional deviation will gradually decrease.

[0021] If the unloading trolley and the reversible distribution conveyor belt move in opposite directions, the positional deviation will gradually increase.

[0022] In one optional implementation, real-time acquisition of the first position of the unloading trolley and the second position of the reversible distribution conveyor belt includes:

[0023] The first position of the unloading trolley and the second position of the reversible distribution conveyor are obtained in real time by infrared radar installed at the first preset position on the plane where the fabric conveyor is located and the second preset position on the plane where the grab bucket bridge crane is located, respectively.

[0024] The position acquisition method designed in this invention utilizes the infrared beam emitted by infrared radar and detects the reflected signal to achieve position measurement. It does not require direct contact with the object being measured, such as an unloading trolley or a belt conveyor, and can effectively avoid the wear, jamming, or signal failure problems caused by mechanical friction of contact sensors, such as encoders and limit switches. It has the advantages of convenient installation, low cost, high accuracy, high real-time performance, and strong robustness.

[0025] In one alternative implementation, the automatic material placement method for a crane garage further includes:

[0026] When the unloading trolley and the reversible distribution belt are synchronized, synchronous unloading is started directly. At the same time, the raw materials to be transferred on the fabric conveyor are unloaded onto the reversible distribution belt via the unloading trolley for transfer. The reversible distribution belt is controlled to synchronously unload the raw materials to be transferred within the target storage area.

[0027] When the unloading trolley and the reversible distribution belt are synchronized, the present invention can directly start synchronous unloading without speed adjustment. At the same time, the raw materials to be transferred on the distribution belt are unloaded onto the reversible distribution belt via the unloading trolley for transfer. The reversible distribution belt is controlled to synchronously unload the raw materials to be transferred within the target storage area, which can achieve fast and reasonable distribution, thereby greatly improving distribution efficiency.

[0028] In an optional implementation, during the process of controlling the reversible distribution belt conveyor to synchronously unload the raw materials to be transferred within the target storage area, the automatic material placement method for the crane garage further includes:

[0029] If there is a new positional deviation between the unloading trolley and the reversible distribution belt conveyor, the speed of the unloading trolley should be readjusted to correct the new positional deviation.

[0030] The present invention also considers the situation where the unloading trolley and the reversible distribution belt are out of sync during the synchronous unloading of raw materials. By detecting whether there is a deviation between their positions in real time, and adjusting the speed of the unloading trolley according to the corresponding deviation value when a positional deviation occurs, the present invention ensures that the unloading trolley and the reversible distribution belt are synchronized in real time, thereby helping to ensure uniform material distribution.

[0031] Secondly, the present invention provides an automatic material placement system for a crane garage, the system comprising:

[0032] Fabric conveyor belt, at least one grab bucket bridge crane, at least two infrared radars and control modules;

[0033] The fabric conveyor belt is equipped with an unloading trolley, and each grab bucket bridge crane is equipped with a reversible distribution conveyor belt.

[0034] Reversible distribution belt conveyors are used to transport raw materials to be transported and to unload them after they arrive at their respective storage areas.

[0035] Infrared radars are installed at the first preset position on the plane where the fabric conveyor belt is located and at the second preset position on the plane where each grab bucket bridge crane is located. Reflective baffles are also installed on the unloading trolley and the reversible distribution conveyor belt.

[0036] A control module is used to execute an automatic material placement method for a crane garage according to the first aspect described above or any corresponding embodiment.

[0037] The automatic fabric distribution system for crane garages of the present invention, through a control module, acquires the first position of the unloading trolley and the second position of the reversible distribution belt conveyor in real time during the operation of the reversible distribution belt conveyor towards the target storage area of ​​the raw materials to be transferred, and determines whether the two positions are synchronized. When the unloading trolley and the reversible distribution belt conveyor are out of sync, the speed of the unloading trolley is adjusted to synchronize the positions of the unloading trolley and the reversible distribution belt conveyor in real time, and synchronous unloading is started. At the same time, the raw materials to be transferred from the fabric distribution belt conveyor are unloaded onto the reversible distribution belt conveyor via the unloading trolley for transfer, and the reversible distribution belt conveyor is controlled to synchronously unload the raw materials to be transferred within the target storage area. This system can overcome the dependence on manual fixed-point unloading in traditional fabric distribution, realize the full automation of fabric distribution, and is completely unaffected by human factors and the environment. It effectively avoids uneven fabric distribution, improves fabric distribution efficiency, and meets the needs of automated fabric distribution.

[0038] Thirdly, the present invention provides an automatic material placement device for a hanging garage, the device comprising:

[0039] The ranging module is used to determine the target storage area of ​​the raw material to be transferred, and to obtain the first position of the unloading trolley and the second position of the reversible distribution belt conveyor in real time during the process of driving the reversible distribution belt conveyor to the target storage area.

[0040] The judgment module is used to determine whether the unloading trolley and the reversible distribution belt conveyor are synchronized based on the first position and the second position.

[0041] The material distribution module is used to adjust the speed of the unloading trolley when the unloading trolley and the reversible distribution conveyor are out of sync. This ensures that the unloading trolley and the reversible distribution conveyor are synchronized in real time, and then synchronous unloading is started. At the same time, the raw materials to be transferred from the material distribution conveyor are unloaded onto the reversible distribution conveyor via the unloading trolley for transfer, and the module controls the reversible distribution conveyor to synchronously unload the raw materials to be transferred within the target storage area.

[0042] The automatic material placement device for crane garages of the present invention aims to overcome the shortcomings of traditional material placement methods that rely on manual unloading at fixed points. It can reduce the influence of human factors and the environment, realize the full automation of material placement, thereby avoiding uneven material placement, greatly improving material placement efficiency, and meeting the needs of automated material placement.

[0043] Fourthly, the present invention provides a computer-readable storage medium storing computer instructions for causing a computer to perform an automatic material placement method for a crane garage according to the first aspect or any corresponding embodiment described above.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] This invention provides an embodiment of an automatic material placement method for a hoist garage. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0055] This embodiment provides an automatic material placement method for a crane garage. Figure 1 This is a flowchart illustrating the automatic material placement method for a crane garage according to an embodiment of the present invention, as shown below. Figure 1 As shown, the process includes the following steps:

[0056] Step S101: Determine the target storage area of ​​the raw material to be transferred, and during the process of driving the reversible distribution belt conveyor to the target storage area, obtain the first position of the unloading trolley and the second position of the reversible distribution belt conveyor in real time.

[0057] In this embodiment, the specific content and determination method of the raw materials to be transported and their corresponding target storage areas can be adaptively adjusted according to actual needs, and no detailed restrictions are imposed here. For example, taking glass production in a glass factory as an example, the raw materials to be transported include quartz sand. Considering that the water content and other impurity elements (such as iron, potassium, sodium, aluminum, etc.) of quartz sand will have different degrees of impact on the quality of glass, in actual applications, the factory will test the quartz sand from different manufacturers that enter the factory, and store it in different areas of the hoist garage according to the test results, i.e., the different component contents, for easy access.

[0058] It should be noted that the unloading trolley is a material unloading device used in belt conveyors. Driven by a motor, reducer, and chain, the trolley moves back and forth on the guide rails of the conveyor frame. When the material being conveyed reaches the trolley's position, it falls into the trolley's unloading hopper, thus achieving unloading at any point in the middle of the conveyor. It features a compact and reasonable structure, reliable operation, long service life, convenient maintenance, and low maintenance costs. The reversible distribution belt conveyor is a reversible and mobile belt conveyor mainly used for unloading. It features long-distance continuous multi-point unloading and bidirectional operation for bidirectional unloading, as well as flexible and versatile operation.

[0059] In this embodiment, the specific methods for obtaining the first position of the unloading trolley and the second position of the reversible distribution conveyor belt are not limited in detail and can be adapted according to actual needs. For example, suitable sensors can be selected, such as infrared radar (which detects the reflected signal of an object by emitting an infrared beam, calculates the distance and solves the position), lidar (which measures the distance using the time-of-flight of a laser pulse), and vision sensors (which capture images of the conveyor belt and trolley and combine them with image recognition algorithms, such as feature point matching and optical flow methods, to solve the position). This is only an example for illustration.

[0060] Step S102: Determine whether the unloading trolley and the reversible distribution belt conveyor are synchronized based on the first and second positions.

[0061] In this embodiment, the positional synchronization between the unloading trolley and the reversible distribution conveyor can be determined by their positional deviation. The specific determination method can be adaptively adjusted according to actual needs. For example, assuming the positional deviation is within the allowable range, the two are considered to be in sync when the absolute positional difference is less than or equal to a set threshold; or, if the two continue to move and their relative velocity (i.e., the rate of change of positional deviation) approaches zero, they are considered to be in sync. This can effectively prevent the deviation from continuously increasing or decreasing and achieve a stable relative motion trend. This is only an example.

[0062] Step S103: When the unloading trolley and the reversible distribution belt are out of sync, the unloading trolley is adjusted to make the unloading trolley and the reversible distribution belt synchronized in real time. Then, synchronous unloading is started. At the same time, the raw materials to be transferred on the fabric conveyor are unloaded onto the reversible distribution belt via the unloading trolley for transfer. The reversible distribution belt is controlled to synchronously unload the raw materials to be transferred in the target storage area.

[0063] It should be noted that the speed adjustment operation in this embodiment includes speed increase and speed decrease. The specific speed adjustment value can be adaptively adjusted according to actual needs, such as reducing the speed to 0.8 times the current value. This is only an example.

[0064] The automatic material distribution method for a hoist garage according to this invention first determines the target storage area of ​​the raw material to be transferred. During the operation of the reversible distribution conveyor belt towards the target storage area, the first position of the unloading trolley and the second position of the reversible distribution conveyor belt are acquired in real time, and it is determined whether their positions are synchronized. If the unloading trolley and the reversible distribution conveyor belt are not synchronized, the speed of the unloading trolley is adjusted to synchronize their positions in real time. Synchronous unloading is then initiated, and the raw material to be transferred from the material distribution conveyor belt is unloaded onto the reversible distribution conveyor belt via the unloading trolley. The reversible distribution conveyor belt is controlled to synchronously unload the raw material to be transferred within the target storage area. This achieves full automation of material distribution, overcoming the dependence on manual fixed-point unloading in traditional material distribution. It is completely unaffected by human factors and the environment, further avoiding uneven material distribution, greatly improving material distribution efficiency, and meeting the requirements for automatic and efficient material distribution.

[0065] This embodiment provides an automatic material placement method for a crane garage. Figure 2 This is a flowchart illustrating another automatic material placement method for a crane garage according to an embodiment of the present invention, as shown below. Figure 2 As shown, the process includes the following steps:

[0066] Step S201: Determine the target storage area of ​​the raw material to be transferred, and during the process of driving the reversible distribution belt conveyor to the target storage area, obtain the first position of the unloading trolley and the second position of the reversible distribution belt conveyor in real time.

[0067] Specifically, step S201 includes:

[0068] Step S2011: The first position of the unloading trolley and the second position of the reversible distribution conveyor are obtained in real time by infrared radar installed at the first preset position on the plane where the fabric conveyor is located and the second preset position on the plane where the grab bucket bridge crane is located.

[0069] It should be noted that lidar ranging is suitable for high-precision scenarios, but it has drawbacks such as high maintenance costs and poor environmental adaptability (dust protection required); visual sensors are suitable for auxiliary monitoring and anomaly detection scenarios, but they also have drawbacks such as high maintenance costs and poor environmental adaptability (depending on lighting); in contrast, infrared radar ranging has low maintenance costs, excellent environmental adaptability and is widely used in industrial warehousing scenarios, so infrared radar ranging is selected in this embodiment.

[0070] In this embodiment, the specific process of infrared radar ranging includes: first, selecting an industrial-grade infrared radar (such as Sick DT50, Keyence IL-600, etc.); then, installing the infrared radar at a first preset position on the plane where the fabric conveyor belt is located and at a second preset position on the plane where each grab bucket crane is located, with the height flush with the laser reflector (or metal target surface) of the unloading trolley to avoid the influence of vibration during belt belt operation; simultaneously, installing an infrared reflector (such as a white diffuse reflector or metal corner reflector) on the unloading trolley to ensure that the radar beam is perpendicularly incident to obtain a stable echo. After the infrared radar is installed according to the above process, calibration tests can be performed, and then relevant data can be collected to determine the corresponding positions of the fabric conveyor belt and the reversible distribution belt belt.

[0071] In this embodiment, the specific contents of the first and second preset positions can be adaptively adjusted according to actual needs. For example, one infrared radar is installed on a fixed wall on the plane directly opposite the head of the fabric conveyor belt to measure the position of the unloading trolley on the fabric conveyor belt in real time. The position of the unloading trolley on the fabric conveyor belt is the distance between the starting point and the location of the unloading trolley. Another infrared radar is installed on the platform of the grab bucket crane (i.e., on a fixed wall on the plane where the crane is located) to measure the position of the crane's unloading belt in real time. The position of the reversible distribution conveyor belt on the grab bucket crane is the distance between the starting point and the location of the reversible distribution conveyor belt. This is only an example. This embodiment of the invention uses the infrared beam emitted by the infrared radar and detects the reflected signal to obtain the position measurement method. It does not require direct contact with the measured object, such as the unloading trolley or the conveyor belt, which can effectively avoid the wear, jamming or signal failure problems caused by mechanical friction of contact sensors, such as encoders and limit switches. It has the advantages of convenient installation, low cost, high accuracy, high real-time performance and strong robustness.

[0072] Step S202: Determine whether the unloading trolley and the reversible distribution conveyor are synchronized based on the first and second positions. For details, please refer to [link to relevant documentation]. Figure 1 Step S102 of the illustrated embodiment will not be described again here.

[0073] Step S203: When the unloading trolley and the reversible distribution belt are out of sync, the unloading trolley is adjusted to make the unloading trolley and the reversible distribution belt synchronized in real time. Then, synchronous unloading is started. At the same time, the raw materials to be transferred on the cloth conveyor are unloaded onto the reversible distribution belt via the unloading trolley for transfer. The reversible distribution belt is controlled to synchronously unload the raw materials to be transferred in the target storage area.

[0074] Specifically, step S203 includes:

[0075] Step S2031: When the unloading trolley and the reversible distribution belt conveyor are out of sync, calculate the positional deviation between the first position and the second position.

[0076] In this embodiment, the position deviation is obtained by subtracting the first position from the second position.

[0077] Step S2032: Determine the change in position deviation, and based on the change, adjust the speed of the unloading trolley and the reversible distribution conveyor accordingly to ensure that their positions are synchronized in real time. The change in position deviation includes both a gradual increase and a gradual decrease. If the position deviation gradually increases, the speed of the unloading trolley is reduced accordingly; if the position deviation gradually decreases, the speed of the unloading trolley is increased accordingly.

[0078] It should be noted that, based on the principle of relative motion, when the positional deviation between the unloading trolley and the reversible distribution conveyor belt gradually increases, it indicates that the relative motion directions of the two trolleys are opposite or the speed difference is too large (for example, the trolley moves to the left and the conveyor belt moves to the right, or one side's speed is significantly higher than the other). At this time, reducing the speed of the trolley or increasing the speed of the conveyor belt can directly reduce the relative speed difference between the two, inhibiting the deviation from further expanding. This avoids "uncontrolled separation" caused by excessive speed difference, such as the unloading trolley and the conveyor belt's discharge port becoming increasingly far apart, causing the material to fail to connect accurately. It also provides the system with adjustment time, preventing the deviation from exceeding the safety threshold and triggering an emergency shutdown, thus improving process continuity. When the positional deviation between the unloading trolley and the reversible distribution conveyor belt gradually decreases, it indicates that the two trolleys are moving in opposite directions or the speed difference is narrowing (e.g., the trolley is catching up with the conveyor belt). At this time, increasing the speed of the trolley or decreasing the speed of the conveyor belt can accelerate the reduction of the remaining deviation and shorten the synchronization time. This can avoid synchronization lag caused by "conservative speed adjustment", such as adjusting at a low speed when close to synchronization, which wastes time, and can prevent over-adjustment from causing the deviation to increase in the opposite direction (e.g., the trolley overtakes after catching up because the speed is not reduced in time), thus achieving "precise contact with the synchronization point".

[0079] In this embodiment, determining the change in position deviation in step S2032 includes:

[0080] Step A1: Obtain the first running direction and first running speed of the unloading trolley corresponding to the current position, and the second running direction and second running speed of the reversible distribution belt conveyor.

[0081] It should be noted that the specific methods for determining the first running direction and first running speed of the unloading trolley, and the second running direction and second running speed of the reversible distribution conveyor belt in this embodiment are not limited and can be adjusted adaptively according to actual needs. For example, an incremental encoder can be used to output two pulse signals (phase a and phase b) with a 90° phase difference, and the direction can be determined by the pulse sequence; if phase a leads phase b, it is determined to be the positive direction (e.g., the conveyor belt is running in the forward direction, and the trolley is moving to the right); if phase b leads phase a, it is determined to be the reverse direction; or, proximity switches can be used, specifically, proximity switches (e.g., photoelectric switches, magnetic switches) can be installed at both ends of the track or at key positions. When the trolley moves from left to right, the left switch is triggered first, and then the right switch is triggered, and the direction is determined by the switch triggering sequence; the reverse is also true; the speed can be determined by the encoder pulse counting method, that is, by calculating the linear velocity or rotational speed by the number of encoder pulses per unit time; or millimeter-wave radar speed measurement can be used, that is, by measuring the speed by the frequency change (difference frequency principle) of the radar wave reflected signal, which is only used as an example.

[0082] Step A2: When the first running direction is the same as the second running direction, determine whether the first running speed is greater than the second running speed.

[0083] Step A3: If the first running speed is greater than the second running speed, then the position deviation is determined to gradually decrease.

[0084] Step A4: If the first running speed is less than the second running speed, then the position deviation is determined to be gradually increasing.

[0085] In this embodiment of the invention, by acquiring the running speed and direction of the unloading trolley and the reversible distribution belt at their current positions, and determining the changes in their positional deviation based on the running speed and direction, the changes in the positional deviation between the unloading trolley and the reversible distribution belt can be accurately determined, thereby improving the subsequent speed adjustment accuracy and helping to improve the accuracy and reliability of material distribution.

[0086] It should be noted that when the first running direction is different from the second running direction, the determination of the change in position deviation in step S2032 above includes:

[0087] In step B1, if the unloading trolley and the reversible distribution conveyor belt are moving in opposite directions, then the positional deviation is determined to gradually decrease.

[0088] In step B2, if the unloading trolley and the reversible distribution conveyor belt are moving in opposite directions, the positional deviation is determined to be gradually increasing.

[0089] Step S2033: Start synchronous unloading. At the same time, unload the raw materials to be transferred from the fabric conveyor belt to the reversible distribution conveyor belt via the unloading trolley for transfer, and control the reversible distribution conveyor belt to synchronously unload the raw materials to be transferred in the target storage area.

[0090] In this embodiment of the invention, by tracking the positional deviation between the unloading trolley and the reversible distribution belt conveyor in real time and adjusting their respective speeds accordingly, the unloading trolley and the belt conveyor are kept in coordination during operation. This avoids material conveying interruptions, accumulation, or spillage caused by asynchronous positioning, greatly improving the continuity and efficiency of material distribution. It also helps to reduce labor costs and thus reduce the risk of operational errors, achieving highly efficient automated material distribution.

[0091] Step S204: When the unloading trolley and the reversible distribution belt are synchronized, start the synchronous unloading directly. At the same time, unload the raw material to be transferred on the cloth conveyor onto the reversible distribution belt via the unloading trolley for transfer, and control the reversible distribution belt to synchronously unload the raw material to be transferred in the target storage area.

[0092] In this embodiment of the invention, when the unloading trolley and the reversible distribution belt are synchronized, no speed adjustment is required. Synchronous unloading can be started directly. At the same time, the raw materials to be transferred on the distribution belt are unloaded onto the reversible distribution belt via the unloading trolley for transfer. The reversible distribution belt is controlled to unload the raw materials to be transferred synchronously within the target storage area, which can achieve fast and reasonable distribution, thereby greatly improving distribution efficiency.

[0093] It should be noted that, due to the large storage area specified for the raw materials to be transferred in practical applications, the unloading trolley and the reversible distribution conveyor are prone to misalignment during synchronous unloading. Therefore, in the process of controlling the reversible distribution conveyor to synchronously unload the raw materials to be transferred within the target storage area, the automatic material distribution method of the crane garage in this embodiment further includes: if a new positional deviation exists between the unloading trolley and the reversible distribution conveyor, the speed of the unloading trolley is readjusted to correct the new positional deviation.

[0094] It is important to note that in this embodiment, if there is a positional deviation between the unloading trolley and the reversible distribution conveyor belt during the unloading process, the corresponding positional deviation value needs to be determined based on their current positions and running directions. Then, the speed of the unloading trolley is adjusted accordingly based on this deviation value to achieve real-time correction of the positional deviation. Specifically, this embodiment considers the possibility of asynchronous positions between the unloading trolley and the reversible distribution conveyor belt during the synchronous unloading of the raw materials. By detecting whether there is a positional deviation between the two in real time, and adjusting the speed of the unloading trolley according to the corresponding deviation value when a positional deviation occurs, the real-time position synchronization between the unloading trolley and the reversible distribution conveyor belt is ensured, thereby helping to ensure uniform material distribution.

[0095] This embodiment also provides an automatic material placement system for a crane garage. Figure 3 This is a structural block diagram of an automatic material placement system for a crane garage according to an embodiment of the present invention, as shown below. Figure 3 As shown, the system includes: a material distribution conveyor 1, at least one grab bucket bridge crane 2, at least two infrared radars 3, and a control module 4; the material distribution conveyor 1 is equipped with an unloading trolley 11, and each grab bucket bridge crane 2 is equipped with a reversible distribution conveyor 21; the reversible distribution conveyor 21 is used to transport the raw materials to be transported and unload them after reaching their corresponding storage areas; each infrared radar 3 is installed at a first preset position on the plane where the material distribution conveyor 4 is located and at a second preset position on the plane where each grab bucket bridge crane 2 is located, and reflective baffles are installed on the unloading trolley 11 and the reversible distribution conveyor 21 respectively; the control module 4 is used to execute the above-described automatic material distribution method embodiment and preferred embodiment of the crane garage, and will not be repeated hereafter.

[0102] The control module also includes a communication interface 30 for the main control chip to communicate with other devices or communication networks.

[0103] The automatic fabric distribution system for a crane garage, as described in this invention, uses a control module to acquire the first position of the unloading trolley and the second position of the reversible distribution belt conveyor in real time during the operation of the reversible distribution belt conveyor towards the target storage area of ​​the raw material to be transferred. It then determines whether the two positions are synchronized. When the unloading trolley and the reversible distribution belt conveyor are out of sync, the unloading trolley is adjusted to synchronize their positions in real time, initiating synchronous unloading. Simultaneously, the raw material to be transferred from the fabric distribution belt conveyor is unloaded onto the reversible distribution belt conveyor via the unloading trolley for transfer. The system also controls the reversible distribution belt conveyor to synchronously unload the raw material within the target storage area. This overcomes the reliance on manual fixed-point unloading in traditional fabric distribution, achieving full automation of fabric distribution. It is completely unaffected by human factors and the environment, effectively avoiding uneven fabric distribution, improving fabric distribution efficiency, and meeting the requirements of automated fabric distribution.

[0104] In practical applications, the material feeding system in glass factories generally includes two processes: homogenization silos and overhead crane silos. The overhead crane silos typically have a larger storage capacity. Figure 5 This is a schematic diagram of the crane garage process. Figure 5It is known that the hoist garage uses a bucket elevator or belt conveyor for loading, a grab crane for unloading, and a screening system to deliver the material to the top of the raw material workshop silo. Traditionally, the material is directly laid out using a trolley on a conveyor belt, but the placement of the trolley depends entirely on manual, point-to-point unloading, making it highly susceptible to human error and prone to uneven material distribution. Furthermore, the entire process can only be semi-automated. Based on this, this embodiment proposes an automatic fixed-point uniform material distribution method for a crane garage. The automatic uniform material distribution part mainly consists of a material distribution belt conveyor (including a belt unloading trolley) and a grab bucket bridge crane (including a reversible distribution belt conveyor, also known as a reversible unloading belt conveyor). The raw material to be transported is quartz sand, and the control module is a PLC control system. One radar infrared unit is installed at the head of the material distribution belt conveyor to measure the position of the unloading trolley on the material distribution belt in real time (referring to the position of the unloading trolley on the material distribution belt, i.e., the distance between the starting point and the position of the unloading trolley). Another radar infrared unit is installed on the platform of the grab bucket bridge crane to measure the position of the crane unloading belt in real time (referring to the position of the reversible distribution belt conveyor on the grab bucket crane, i.e., the distance between the starting point and the position of the reversible distribution belt conveyor). The measured data is sent to the PLC control system in real time. Alternatively, one radar infrared unit is installed at the head of the material distribution belt conveyor, and corresponding reflective baffles are set on the unloading trolley and the reversible distribution belt conveyor to collect distance data in real time. The above-mentioned uniform material distribution method is as follows: when the belt transports the quartz sand to the material distribution belt, the unloading trolley on the material distribution belt unloads it onto the reversible distribution belt conveyor attached to the grab bucket bridge crane, and then the reversible distribution belt conveyor transports the quartz sand to the designated area for automatic reciprocating uniform material distribution.

[0105] In this embodiment, a PLC control system processes the distance measurement data, analyzes the speeds of the unloading trolley and the reversible distribution conveyor belt, and determines whether they are in a matched position. The PLC program adjusts the speed and position in real time. Specifically, the PLC control system first determines the positions of the unloading trolley and the reversible distribution conveyor belt based on the real-time collected data. When the unloading trolley and the reversible distribution conveyor belt are in the same position, they maintain synchronous operation according to the initially set speed, without the need for speed adjustment. When the positional deviation between the unloading trolley and the reversible distribution conveyor belt exceeds the set value during movement, the speed needs to be corrected in time. That is, when the unloading trolley speed is too fast, the speed is adjusted to reduce it to 80% of the current value, and then compared again with the collected distance data, repeating the adjustment until the two positions are synchronized. When the unloading trolley speed is too slow, the speed is modified to increase it to 1.15 times the current value, and then compared again with the collected distance data, repeating the adjustment until the positions are synchronized. It should be noted that the PLC control system has multiple built-in PLC programs to achieve corresponding functions, such as a distance measurement program (for distance measurement) and a speed adjustment program (for adjusting the speed of the unloading trolley and the reversible distribution conveyor belt). Then, a left (right) movement judgment program (i.e., a PLC program written according to actual needs, which is used by the reversible distribution conveyor belt to give the unloading trolley running direction instructions, such as controlling the unloading trolley to run left or right according to the actual program instructions) is used. At this time, the reversible distribution conveyor belt can automatically and evenly distribute materials in the designated area, replacing the previous operation of positioning control by operators on site with a remote control, and realizing unattended digital and automated control.

[0106] In this embodiment, refer to Figure 5 The feeding section involves a grab bucket crane grabbing the quartz sand and placing it into a feeding hopper. The quartz sand is then discharged onto a belt conveyor via a vibrating hopper feeder and a flat shaking screen. From there, it is transported to a designated silica sand silo via the belt conveyor and bucket elevator. This embodiment's automatic fixed-point uniform material distribution method in the crane garage enables automated material handling and feeding, ensuring the sand is loose and better suited for subsequent needs. Furthermore, it eliminates the need for manual operation of a sand rake to rake the quartz sand onto the belt conveyor, freeing it from the subjective experience of operators.

[0107] In this embodiment, the hardware selection for the above-mentioned automatic fixed-point uniform material distribution method for the hoist garage includes:

[0108] 1. The main PLC model for the crane garage is Siemens.

Figure 6 The diagram shows the automatic material placement simulation operation of the crane garage; the actual material placement effect can be seen in the diagram. Figure 7 The image shows a rendering of an automatic material placement system for a crane garage. It should be noted that... Figure 6 The medium sandstone silo serves as the raw material workshop's storage area. Based on the actual layout of the raw material workshop's storage areas, it is divided into north and south sandstone silos, with corresponding cranes installed on both sides of the sandstone silos. Figure 6 The East Cart Pattern (including 1 and 2) and West Cart Pattern (including 1 and 2) are the storage areas for sandstone raw materials.

[0116] 2. Feeding and uniform distribution can be completed simultaneously.
