[0031] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0032] like Figure 1 The flowchart of the material transportation control method provided by the first embodiment of the present invention is a material transportation control method, the control method comprises the following steps S10-S14.

[0033] S10. Constructing a plurality of transport processes corresponding to a plurality of material transport production lines according to the plurality of material transport production lines.

[0034] Among them, each transportation process includes a discharge equipment number, a conveyor number, a discharge port number and a downstream equipment number corresponding to the discharge port, and the multiple material transportation production lines share one conveyor.

[0035] Specifically, the embodiment of the present invention mainly uses PLC to control various devices on the material transportation production line. Multiple material transportation production lines refer to multiple production lines involved in actual production. Figure 2 It is a control circuit diagram corresponding to multiple transportation production routes provided in an embodiment of the present invention.

[0036] For example, Figure 2B1SR represents the discharging device, B101 represents the conveyor belt of the discharging device, and B102SHR represents the conveyor. The conveyor in the embodiment of the present invention mainly refers to the shuttle belt conveyor. Among them, B101 is perpendicular to the conveyor B102SHR, KK101, QJ101, QK101, KF201 and KF101 represent 5 discharging ports at different positions, KK102-KK106, ..., KF202-KF205, KF101-KF105 represent the downstream equipment corresponding to each discharging port, and users 1 and 2 are used to represent the location of the final processing of the material (which can be set according to actual needs). Thus, multiple material transport production lines can be formed, and multiple transport processes can be created based on the multiple transport production lines, such as B1SR-B101-B102SHR-KF201-KF202-KF203-KF204-KF205, B1SR-B101-B102SHR-KF101-KF102-KF103-KF104-KF105, and so on, which are not listed one by one here. According to the multiple transport processes of the label group of these equipment, the embodiment of the present invention mainly refers to sharing the same conveyor B102SHR and the same discharge equipment B1SR (including the matching conveyor belt B101), which is used to control the movement and running direction of the conveyor to transport the materials to the corresponding discharge port, and transmit the discharge material to the downstream equipment at the discharge port through the discharge port, so as to realize the linkage control of each equipment on the entire transportation line. Of course, for a production and transportation line with multiple different discharging devices and multiple conveyors, the control principle is the same as the control principle of the present application, so the control method after a simple deformation belongs to the protection scope of the embodiment of the present invention.

[0037] S11. Determine, according to the control instruction, from the multiple transportation processes a first target transportation process corresponding to the control instruction.

[0038] Specifically, when multiple transportation processes corresponding to multiple production processes are created according to the above steps, in order to realize automatic transportation, multiple control instructions are set for the multiple transportation processes. During the production and transportation process, the corresponding control instructions can be manually selected or the corresponding control sequence can be set in advance to issue control instructions. For example, if the control instruction is manually selected and the transportation process corresponding to the control instruction is: B1SR-B101-B102SHR-KF201-KF202-KF203-KF204-KF205, then the transportation process is regarded as the first target transportation process. Similarly, the method and principle for selecting the target transportation quality for other control instructions are similar, and will not be repeated here. The target transportation process is used to indicate that the material is transported according to the transportation process, and the material is transported from the discharge equipment B1SR and B101 to the discharge port number KF201 and transported and processed by the downstream equipment KF202, KF203, KF204 and KF205.

[0039] S12. Determine the discharge equipment number, conveyor number, discharge port number, and downstream equipment number corresponding to the discharge port according to the first target transportation process.

[0040] Specifically, when the first target transport process B1SR-B101-B102SHR-KF201-KF202-KF203-KF204-KF205 is determined according to the above step S11, the labels of the various equipment in the transport process are correspondingly determined, including the discharge equipment label B1SR (matching the conveyor belt B101), the conveyor label B102SHR, the discharge port label KF201, and the downstream equipment of the discharge port label KF202, KF203, KF204 and KF205.

[0041] The transport process can be understood as a sequence table. The shuttle belt conveyor has its own index number in the process table. The variable of this index number is the mark for identifying the device when the process is selected. When the device is selected by the process, it is necessary to judge the status of the device and send a command to the underlying control program module.

[0042] The control module of the shuttle belt conveyor is hierarchical control. The first part is the logical variable interface for docking the overall process. Assume that the name of the conveying motor of the shuttle belt conveyor is B102SHR. The shuttle belt conveyor includes the travel motor B102SHR_MD and the conveyor belt motor. Table 1 is the logical variable interface of the conveyor process table.

[0043]

[0044]

[0045] Table 1

[0046] After conveyor B102SHR is selected by the process, the Boolean variables B102SHR_in_use and B102SHR_MD_CON.InFlow are set to 1, indicating that the conveyor belt and mobile motor of the shuttle belt conveyor are selected by a process. At this time, the single machine operation is invalid and the equipment is occupied by the process. After the equipment is occupied, Figure 2 This equipment cannot be selected in other transport processes (except when the switching status is activated), and the equipment is displayed in blue on the screen to indicate that it is selected.

[0047] S13. Initialize the discharging equipment, conveyor and downstream equipment corresponding to the first target transportation process according to the discharging equipment number, conveyor number, discharge port number and downstream equipment number corresponding to the discharge port.

[0048] Furthermore, the conveyor includes a machine-side operation mode, a centralized control mode and an emergency stop mode.

[0049] Specifically, in order to ensure the diversity of production control, the conveyor in the embodiment of the present invention includes multiple operation modes: machine-side operation mode. When only controlling at the machine side, the selection switch of the machine-side box is turned to the "machine-side" operation mode. There are start-stop belt buttons and start-stop moving motor buttons in the machine-side box. It can stop at any position. The positioning switch is invalid for machine-side operation, and positioning depends entirely on manual judgment. Machine-side operation is separated from PLC operation and is operated on-site. It is often used for mechanical maintenance equipment. However, some steel companies are still using this method in production. The production method is backward and intelligent production cannot be achieved.

[0050] For shuttle belt conveyors, the transmission motor and the travel motor share a machine-side box. The machine-side, centralized, and emergency stops work on both motors, which is convenient for manual maintenance. When the pull rope switch stops, both motors stop working. The main control points of the conveyor are shown in Table 2.

[0052] Table 2

[0053] In centralized mode, it is divided into single action and linkage. In single action, it is not controlled by the process, that is, it is not combined with other equipment to form a conveying process. Linkage is to realize process operation, which can be realized by manual linkage and automatic linkage. Manual linkage requires operator intervention to complete the process operation step by step (process initialization, process startup, process switching, process sequential stop, process emergency stop). Automatic linkage is that the intelligent management system selects the process and issues instructions, and the others are executed by the equipment itself. The present invention is mainly implemented in the linkage mode under the centralized mode, and mainly describes the full automatic control of the equipment after receiving the selected process. In the emergency stop mode, the equipment is often stopped in an emergency, mainly to prevent excessive current and burnout of the equipment when the equipment fails.

[0054] The shuttle belt conveyor is a device. To achieve full automation, it must be combined with the process to make the operation of the equipment meaningful. That is, the individual functions must be reflected through the whole. The flow chart is a mesh structure composed of multiple conveyors. A flow chart is one of the paths, and the material flow direction is unidirectional. To achieve full automation, the intelligent production management system must send instructions to the PLC control system of the shuttle conveyor, and it is realized by building different control layers in the PLC. The program block of the shuttle conveyor needs to dock with the process control word and return the status word. In view of the characteristics of process control, the process automatic control function of the equipment is invented. There are mainly a series of start-up and operation processes such as process selection, process initialization, process sequence start, and process operation. After the transportation of materials is completed, the process sequence stops. If the process is switched midway, the process switching function needs to be started.

[0055] The embodiment of the present invention mainly utilizes the linkage mode under the centralized mode to closely link the belt operation, travel motor drive and flow chart of the shuttle belt conveyor. It has both the maintenance function beside the machine and the single-action function of the equipment during remote operation, and at the same time realizes the full automatic control function of the shuttle belt conveyor in production.

[0056] When the equipment is selected by the process, a series of logical variables are required to judge the status of the equipment and send commands to the underlying control program module. According to the above step S12, when the equipment numbers corresponding to the first target process are determined, the discharge equipment, conveyor and downstream equipment corresponding to the discharge port corresponding to the first target transportation process are determined, and the equipment numbers are the unique identifiers of the equipment.

[0057] Process initialization: After the process selection is completed, the downstream discharge port of the shuttle conveyor is determined. For example, in the first target transportation process selected by the present invention, the discharge port corresponds to KF101. At this time, the program automatically triggers the process initialization command through the flag selected by the process, the process starts to initialize, the conveyor starts to move, and the program module of the walking motor is called in the program. During the walking process, sound and light warnings are issued (its function is to remind the surrounding operators to avoid operating the equipment when the equipment is ready to start to prevent accidents). The function of initialization is to return the equipment to its original position and wait for startup. After initialization is completed, the B102SHR_zb_pos_ok status is set to 1, indicating that the induction plate of B102SHR is aligned with the discharge port KF101. When all equipment initializations in this process are completed, the process can be started. In this patent, the automatic identification of the discharge port position is automatically determined by the program. According to the equipment position and the motor drawing design, the relationship between the equipment and the running direction of the walking motor are determined after the program calibration, and the function of continuing to walk when passing a certain discharge port position that is not in this process is identified. The implementation method of this process adopts the existing technology and will not be repeated here.

[0058] S14. Start the discharging equipment, conveyor, discharge port and downstream equipment corresponding to the first target transportation process in sequence according to the set material flow direction.

[0059] Specifically, in some embodiments, in order to ensure line safety, the process starts sequentially: after the process initialization is completed, this status flag triggers the process start event, and the process starts automatically, starting in sequence according to the material flow direction set in advance, which includes the reverse material flow and the forward material flow direction (for example, the conveyor belt from the discharge device to the discharge device, the conveyor, and the downstream device corresponding to the discharge port). Or according to the set material flow direction (for example, the reverse material flow direction: for example, the downstream device corresponding to the discharge port, the conveyor, and the discharge device).

[0060] When the B102SHR shuttle belt conveyor starts, the program calls the program module of the transmission motor, and the transmission motor starts to sound an alarm, which is generally set to 30 seconds. After the alarm stops, the transmission motor starts forward or reverse, and the B102SHR_starting variable is set to 1. The device flashes green and gray alternately on the screen, indicating that the device is not stable yet. After 15 seconds, the device enters a stable state and the slipping and sealing speed ends. The B102SHR_run variable is set to 1, and the device displays a permanent green on the screen, indicating that the device is running smoothly and the device startup is complete.

[0061] The sequential starting of devices in the embodiment of the present invention can avoid instantaneous current overload when the line is started, thereby ensuring the safety of the line.

[0062] Furthermore, after the step of initializing the discharging equipment, conveyor and downstream equipment corresponding to the discharge port corresponding to the first target transportation process, the control method further includes: obtaining the operating status of the discharging equipment, conveyor and downstream equipment corresponding to the discharge port on the first target transportation process. The operating status includes a normal state and an abnormal state; when the operating status is a normal state, the discharging equipment, conveyor and downstream equipment corresponding to the discharge port on the first target transportation process are started in sequence according to the set material flow direction; or, when any equipment on the first target transportation process is in an abnormal state, an alarm is issued.

[0063] Specifically, in some embodiments, since the various devices in the embodiments of the present invention are controlled in linkage, the entire production and transportation process can only be smoothly carried out when each device is in a normal state. Therefore, after initialization, it is necessary to further obtain the operating status of the discharge equipment B1SR, the conveyor B102SHR and the downstream equipment KF201, KF202, KF203, KF204 and KF205 corresponding to the discharge port on the first target process. The method of detecting the operating status of the equipment can be achieved through the existing detection method, and the embodiments of the present invention do not make specific restrictions.

[0064] When any equipment in the first target transportation process is detected to be in an abnormal state, the startup will be suspended and an alarm will be issued to remind the staff to check the equipment status. For example, they can check whether the belt is deviating or blocked, and then eliminate the danger in time to ensure the normal operation of the equipment.

[0065] When it is detected that the operation status of the discharge equipment, conveyor and downstream equipment corresponding to the discharge port in the first target transportation process are all normal, they are started in sequence according to the set material flow direction (for example, from the discharge equipment to the conveyor belt, conveyor and downstream equipment corresponding to the discharge port of the discharge equipment), or vice versa (for example, the downstream equipment, conveyor and discharge equipment corresponding to the discharge port). Starting in sequence can avoid instantaneous overload of the line when the equipment is started, ensuring the safety of the line.

[0066] The embodiment of the present invention can ensure the smooth progress of the production process and avoid accidents by detecting the operating status corresponding to the first target transportation process and issuing an alarm when any device is detected to be in an abnormal state, thereby promptly reminding the staff.

[0067] S15. Control the running direction of the conveyor according to the unloading port corresponding to the first target transportation process.

[0068] Specifically, in some embodiments, the first target transportation process includes the label KF101 of the corresponding discharge port. Among them, the position of the discharge device and the conveyor belt B101 configured for the discharge device remains unchanged during the whole process, and the conveyor B102SHR moves according to the position of the discharge port, with a movement range of five discharge ports from KK101 to KF201, and the conveyor belt B102SHR is perpendicular to the conveyor B102SHR, and the length of the conveyor B102SHR is to ensure that when moving between the five discharge ports from KK101 to KF201, the conveyor belt B101 can transport materials to B102SHR. Therefore, when the discharge port is obtained, the movement direction of the conveyor B102SHR can be controlled according to the position of the discharge port.

[0069] Furthermore, the conveyor includes a travel motor and a transmission motor, the travel motor is used to control the movement direction of the conveyor, and the transmission motor is used to control the rotation direction of the conveyor belt of the conveyor.

[0070] Specifically, in a steel plant, there are usually various belt conveyors for transporting various raw materials for production links, among which the shuttle belt conveyor has two sets of drive devices, wherein the transmission motor 101 (refer to Figure 3 ) is used to drive the conveyor belt, using a motor and a reducer, and can run in forward and reverse directions. Travel motor 102 (reference Figure 3) is used for the reciprocating travel drive of the entire conveyor, and is mainly used for the overall operation of an empty conveyor. It also adopts a motor reducer to ensure that the equipment is stable during normal parking and emergency braking (sudden power failure). The embodiment of the present invention is mainly aimed at the automatic control of the conveyor, realizing automatic control of material transportation, no longer needing to rely on manual control, saving labor costs, and reducing the error rate of manual errors. It should be noted that the embodiment of the present invention is mainly suitable for shuttle belt conveyors.

[0071] According to the unloading port corresponding to the first target transportation process, controlling the running direction of the conveyor includes the following steps S151-S152.

[0072] S151. Control the movement direction of the travel motor according to the unloading port corresponding to the first target transportation process.

[0073] Specifically, in some embodiments, the conveyor includes a travel motor and a transmission motor, the variable of the travel motor corresponds to B102SHR_MD_CON.InFlow in Table 1, and the variable corresponding to the transmission motor is B102SHR_in_use. Figure 3 is the positional relationship between the conveyor and each material discharge port, where Figure 3 The feed port 1# corresponds to Figure 2 KK101, 2# corresponds to Figure 2 In QJ201, position 3 corresponds to QK101, position 4 corresponds to KF101 and position 5 corresponds to KF201.

[0074] This conveyor has 5 unloading ports on the transport production line, which is the shuttle belt conveyor with the most unloading positions currently designed. During the process design, the length of the shuttle belt conveyor is equal to the distance between two unloading ports. Figure 3 As shown, the distance between position 1# and position 4#, and the distance between position 2# and position 5# are equal to the length of the shuttle belt conveyor, so that material can be unloaded to two positions at one position through the forward and reverse drive of the belt.

[0075] The shuttle belt conveyor is equipped with an induction plate and a positioning switch for induction. The induction plate senses the positioning switches at positions 1#, 2#, and 3#. The induction plate is installed on the machine body and moves with the shuttle belt conveyor. The positioning switch is installed on the ground, and there is no positioning switch installed at positions 4# and 5#. Therefore, 5 positions can be controlled with 3 positioning switches. Limit switches are installed on both sides of the positioning switch to protect the movement. When installing the induction plate, it is necessary to determine the welding position, consider the inertia of the shuttle belt conveyor, and also consider that the sensing distance of the positioning switch can be adjusted. The positioning switch is not installed at the discharge port, but is determined by the installation position of the induction plate after walking to the discharge port. For ease of expression, this model diagram is set according to the discharge port position.

[0076] In the embodiment of the present invention, the conveyor includes a travel motor for controlling the overall travel of the conveyor, as follows:

[0077] Table 3 is a logic control table of the running direction of the shuttle belt conveyor travel motor provided in an embodiment of the present invention.

[0078]

[0079]

[0080] Table 3

[0081] The main features of the shuttle belt conveyor are overall movement and multi-position unloading, which increases the flexibility of transportation. During the transportation process, the shuttle belt conveyor is a process switching point, which can reverse the process, improve the equipment operation efficiency, reduce the equipment no-load during the start and stop process, and reduce energy consumption. Figure 3 As shown in the figure, the conveying motor of the shuttle belt conveyor can run in both forward and reverse directions. However, the conveyor cannot carry materials during the overall movement of the conveyor, so the conveying motor will only rotate when the conveyor reaches the target position. Figure 3 As shown, the equipment has 5 positions for unloading. The function can be realized by installing 3 positioning switches. The travel distance is the distance of the 3 positions. The positions of 1# and 4# overlap, and the positions of 2# and 5# overlap. In the program, it is necessary to distinguish which overlapping position is in use according to the unloading direction of the process. When the belt conveyor unloads materials at the 1# unloading port, 2# unloading port, and 3# unloading port, the conveying motor runs forward. When unloading materials at the 4# unloading port and 5# unloading port, the conveying motor runs reversely.

[0082] The conveying motor has the function of forward and reverse operation, and its function has the same control module as the fixed reversible belt conveyor. It mainly includes comprehensive faults of various shutdown fault combinations, motor starting conditions, bell control program, motor forward operation control (linkage and single action), motor reverse operation control (linkage and single action), motor start completion logic judgment, motor operation feedback fault, motor clearing logic control when stopping, logic judgment of motor stopping completion flag, slip signal, deviation signal, blocking signal filtering and processing, and related time settings. The alarm processing program is mainly used to form a memorizable variable for the screen alarm, which is convenient for recording the operator to query the fault situation.

[0083] The main functions of the walking motor control module include motor forward walking logic control (linked and single-action), reverse walking logic control (linked and single-action), forward operation feedback fault judgment, reverse walking feedback fault judgment, each walking timeout fault judgment, forward limit fault lock, reverse limit fault lock, target position logic processing, actual position logic processing, logic processing of continuous walking through position 2, forward request judgment, reverse request judgment, stop request judgment and alarm processing procedure.

[0084] Combination Figure 3 As shown in Table 3, for example, when the current position of the conveyor is position 1# and the target position is position 2#, the conveyor is controlled to reverse and stop when the target position 2# is detected. The control principle of the conveyor for other target positions is the same and will not be described here.

[0085] KF202, KF203, KF204, and KF205 are stopped in sequence, that is, each one is stopped after the material is cleared, and then the next one is stopped after the material is cleared, and so on. Specifically, the time taken for clearing can be calculated according to the length and running speed of the conveyor belt, so that after the time taken for clearing, the downstream equipment of the first target transportation process is stopped in sequence to avoid material blockage.

[0086] S23. Control the running direction of the conveyor according to the unloading port of the second target transportation process.

[0087] Specifically, in some embodiments, when the stop command is issued, the shuttle conveyor travel motor starts to move to the new process discharge port position KK101. During this period, the conveying motor of the shuttle belt conveyor B102SHR has a reversal, then it stops running and quickly starts in the opposite direction automatically.

[0088] When the travel motor completes alignment, the conveyor belt completes reversing, and the original process completes sequential stopping (only stops the part that is different from the new process) KF201~KF205, the management system sends a switch completion signal, the switch status is reset, the original process equipment exits the process, and the switch is completed. The new process starts loading.

[0089] Furthermore, the control method also includes: when it is detected that any one of the discharging equipment, conveyor or downstream equipment corresponding to the first target transportation process or the second target transportation process is in an abnormal state, the discharging equipment, conveyor and the downstream equipment corresponding to the discharge port of the first target transportation process or the second target transportation process are controlled to stop running, and an alarm is issued.

[0090] Specifically, in some embodiments, in order to ensure the normal operation of each target transportation process, when any equipment of the discharging equipment, conveyor or downstream equipment corresponding to the equipment of the first target transportation process or the second target transportation process is in an abnormal state during use, the downstream equipment will all be stopped and an alarm will be issued to avoid safety accidents.

[0091] Accidental shutdown: The equipment stops running when it encounters a downstream equipment failure or its own shutdown failure. The equipment process linkage automatic state disappears, and the linkage automatic state needs to be activated to restart.

[0092] There are two situations when the shuttle belt conveyor mobile motor is switched: shared process equipment (including switching points) and newly added process equipment. For example, B102SHR is a shared device and KK107SHR is a newly added device. The shared process equipment during switching does not change when the initialization command is issued. Only when it is a switching point, it moves or does not move according to the alignment when the process sequential stop command is initiated. The newly added process equipment during switching moves (when the position is not at the starting process equipment) or does not move (when the position is facing the starting process equipment) according to the command to initialize the new process.

[0093] When the process is switched, the commutation of the conveyor belt motor is supplemented by the motor module in the program to avoid the motor being unable to start after stopping during the motor commutation.

[0094] Through the above technical scheme, the present invention determines the first target transport process corresponding to the control instruction from multiple transport processes through the control instruction, and determines the corresponding discharge equipment number, conveyor number, discharge port number and downstream equipment number corresponding to the discharge port according to the first target transport process, so as to determine which equipment will be started in the transport process, and after determining the equipment to be started, initialize the equipment on the first target transport process so that the equipment returns to its position and is ready to start; after the initialization is completed, start the equipment on the first target transport process in turn, and further control the running direction of the conveyor according to the discharge port corresponding to the first target transport process, so that the various equipment corresponding to the first target transport process are controlled in linkage, so as to transport the material from the discharge port to the discharge port through the conveyor, thereby realizing the linkage control of the entire generation line.

[0095] The embodiments of the present invention realize automatic control of material transportation without the need for manual operation, thereby reducing the probability of errors in manual operation and making the material transportation production line more automated, thereby realizing the requirements of intelligent factory production.
