[0002] In the implementation of Factory Automation (FA), conveyor lines in factory workshops typically include multiple rollers, belts, and pallets. Multiple rollers are connected end-to-end to form a continuous conveying surface.

Ultimately, the pallets carrying materials on the conveying surface can be driven to move between various production equipment in the factory workshop, thereby realizing automated material transportation.

[0061] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0062] First, this application provides a conveyor line control system, such as Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the structure of the conveyor line control system provided in an embodiment of the present application. Figure 2A schematic diagram of the position of a conveyor line control system provided in an embodiment of the present application, wherein the system includes: a non-positioning conveying component, a positioning conveying component, and a mover pallet 300 that can be loaded with materials for controlling the operation of a conveyor line arranged in a factory workshop; the conveyor line is divided into alternating non-positioning conveying sections and positioning conveying sections, each non-positioning conveying section is provided with a pallet conveying station, and each positioning conveying section is provided with a production operation station; the pallet conveying station refers to a station whose main function is to convey the mover pallet 300, and the production operation station refers to a station whose main function is to convey the mover pallet 300 to the production operation equipment for the production operation equipment to perform production operations.

[0063] It should be noted that Figure 2 The "M" shown here refers to the motor. Figure 3 、 Figure 8 and Figure 13 The "M" shown also refers to the motor in general.

[0064] In the conveyor line control system provided in the embodiment of the present application, the non-positioning conveying component includes: a first roller 110 arranged in each non-positioning conveying section, a compound motor group 120 arranged in each non-positioning conveying section for driving the non-positioning conveying section to operate, and a first control module 130 connected to the compound motor groups 120 in multiple non-positioning conveying sections for transporting the movable pallet 300 that can be loaded with materials to the positioning conveying section.

[0065] Specifically, in an embodiment of the present application, a conveyor line in a factory workshop for conveying a mover pallet 300 (the mover pallet 300 may carry materials) is divided into alternatingly connected non-positioning conveying sections and positioning conveying sections, and multiple non-positioning conveying sections and positioning conveying sections are arranged in sequence along a straight line and connected end to end to form a circulating continuous conveyor line.

[0066] Among them, the non-positioning conveying section is a conveying section used to convey the mover pallet 300 with relatively low conveying positioning accuracy, and the positioning conveying section is a conveying section used to convey the mover pallet 300 with relatively high positioning accuracy requirements; wherein, the purpose of setting the non-positioning conveying section is to transport the mover pallet to the positioning conveying section, so the non-positioning conveying section mainly considers the fast and stable transportation of the mover pallet, so the non-positioning conveying section has relatively low positioning accuracy requirements; the main function of the positioning conveying section is to realize the precise positioning of the mover pallet 300, and ensure that the mover pallet 300 can be accurately transported to the production operation equipment, so the positioning conveying section has relatively high positioning accuracy requirements.

[0067] like Figure 3 As shown, Figure 3This is a structural schematic diagram of the pallet conveying station provided in an embodiment of the present application, in which a group of first rollers 110 and a compound motor group 120 are provided in each pallet conveying station; wherein the compound motor group 120 includes: a brushless motor 121, a first magnetic drive motor 122, a first magnetic drive encoder 123 and a first magnetic drive driver 124.

[0068] The first roller 110 plays the role of supporting and guiding the mover pallet 300 in the pallet conveying station; the first roller 110 is usually composed of multiple rollers, distributed on both sides or the bottom of the conveying section, and drives the mover pallet 300 to move through rotation; the compound motor group 120 drives the first roller 110 in the pallet conveying station to rotate, so as to drive the non-positioning conveying section to operate.

[0069] The brushless motor 121 provides basic power for the transportation of the mover tray 300. The brushless motor 121 can output power stably to ensure that the mover tray 300 moves on the non-positioning conveying section and meets the basic speed requirements for material transportation.

[0070] The first magnetic drive motor 122 operates based on magnetic levitation technology and the principles of linear motors. It consists of a stator and a mover, with magnetic drive coils arranged on the stator and permanent magnets mounted on the mover. By controlling the current in the stator coils, a variable magnetic field is generated that interacts with the permanent magnets on the mover, achieving linear or rotational motion of the mover. As a result, the first magnetic drive motor 122 offers advantages such as fast response, high positioning accuracy, and smooth operation.

[0071] The first magnetic drive encoder 123 is a sensor for detecting the position information of the mover pallet 300. The first magnetic drive encoder 123 works based on the principle of magnetic induction. By detecting the position changes of the magnetic mark on the mover pallet 300, the position information is converted into an electrical signal output. The first magnetic drive encoder 123 has the advantages of high precision, fast response speed and strong anti-interference ability.

[0072] In actual operation, the brushless motor 121, the first magnetic drive motor 122 and the first magnetic drive encoder 123 can complete the acceleration, deceleration and stopping functions of the mover pallet 300 in the non-positioning conveying section; wherein, the first magnetic drive motor 122 can determine the position of the mover pallet 300 through the first magnetic drive encoder 123 based on the control signal sent by the first control module 130, so as to accurately adjust the conveying speed of the first roller 110 and indirectly adjust the moving speed of the mover pallet 300; when acceleration is required, the first magnetic drive motor 122 can provide additional driving force on the basis of the brushless motor 121 to increase the moving speed of the mover pallet 300; when deceleration is required, the first magnetic drive motor 122 can generate a reverse electromagnetic force to reduce the moving speed of the mover pallet 300.

[0073] In the non-positioning conveying section, the mover pallet 300 may need to be transported to a specific pallet conveying station and then stopped; the composite motor group 120 can accurately control the mover pallet 300 at any pallet conveying station in the non-positioning conveying section; in addition, when facing different load conditions, the composite motor group 120 can automatically adjust the output power of the brushless motor 121 and the first magnetic drive motor 122 to ensure that they are always in the best working state.

[0074] After receiving the control signal sent by the first control module 130, the first magnetic drive driver 124 converts the control signal into a current and / or voltage signal suitable for the operation of the first magnetic drive motor 122; the first magnetic drive driver 124 has high-precision control capabilities and fast response speed, and can achieve precise control of the first magnetic drive motor 122.

[0075] The first control module 130 is connected to the composite motor groups 120 in multiple pallet conveying stations within the multiple non-positioning conveying sections to achieve integrated control of the non-positioning conveying components. Equipped with data processing and command transmission capabilities, the first control module 130 precisely controls the start, stop, and speed adjustment of each composite motor group 120 based on pre-set programs or real-time commands. Furthermore, the first control module 130 also features fault diagnosis and alarm functions. If an anomaly is detected in a composite motor group 120, an alarm is promptly issued and appropriate protective measures are implemented, such as stopping the operation of the conveying section to prevent the fault from escalating.

[0076] In the conveyor line control system provided in the embodiment of the present application, the positioning conveying component includes: a second roller 210 arranged in each positioning conveying section, a magnetic drive motor group 220 arranged in each positioning conveying section for driving the positioning conveying section to operate, and a second control module 230 connected to the magnetic drive motor group 220 in a positioning conveying section for transporting the movable pallet 300 that can be loaded with materials to the production operation equipment in the factory workshop.

[0077] Specifically, in the embodiments of the present application, Figure 4 As shown, Figure 4 A structural schematic diagram of a production work station provided in an embodiment of the present application, wherein a group of second rollers 210 and a magnetic drive motor group 220 are provided in each production work station; wherein, the magnetic drive motor group 220 includes: a second magnetic drive motor 221, a second magnetic drive encoder 222 and a second magnetic drive driver 223; wherein, the second magnetic drive driver 223 is used to realize precise positioning control of the mover pallet 300 in the production work station; the specific functions of the second magnetic drive motor 221, the second magnetic drive encoder 222 and the second magnetic drive driver 223 can refer to the specific functions of the aforementioned first magnetic drive motor 122, the first magnetic drive encoder 123 and the first magnetic drive driver 124, which will not be repeated here.

[0078] In the conveyor line control system provided in the embodiment of the present application, the mover tray 300 is a carrier for loading materials, such as Figure 5 As shown, Figure 5 The schematic diagram of the structure of the mover pallet provided in the embodiment of the present application shows that the mover pallet 300 includes a pallet body 310 and a magnet 320; the pallet body 310 provides a placement platform for materials, and the pallet body 310 is a carrier for the movement of materials on the conveyor line; the pallet body 310 also has the function of connecting and fixing the magnet 320 to ensure that the magnet 320 and the pallet body 310 work together; the magnet 320 is generally made of high-performance permanent magnetic material, and the magnet 320 is the core component of the interaction between the mover pallet 300 and the magnetic drive system. During the operation of the conveyor line, the stator coil is energized to generate a magnetic field, which interacts with the magnetic field of the magnet 320 to generate a driving force, pushing the mover pallet 300 to move in a straight line along the conveyor line or to achieve precise positioning control. By precisely controlling the current of the stator coil, precise control of the speed, acceleration and position of the mover pallet 300 can be achieved.

[0079] In summary, it can be seen that the non-positioning conveying component in the conveyor line control system provided in the embodiment of the present application adopts a composite motor group 120, which can automatically adjust the working state according to different situations, realize rapid and continuous conveying of materials, and improve conveying efficiency; in addition, the positioning conveying component adopts a magnetic drive motor group 220, which has the characteristics of high precision and rapid response, and can ensure that the mover pallet 300 is accurately transported to the production operation equipment, meeting the precise requirements of the production operation for the material position; in addition, the first control module 130 and the second control module 230 have data processing and instruction sending capabilities, and can respectively realize precise control of the non-positioning conveying component and the positioning conveying component, thereby improving the reliability and stability of the conveyor line control system.

[0080] Second, the embodiment of the present application provides a conveyor line control method, which is applied to the first control module 130 in the conveyor line control system; multiple production operation equipment are connected to the operation control module; a pallet conveying station is set on the positioning conveying section, and a production operation station is set on the positioning conveying section; Figure 6 As shown, Figure 6 The present invention provides a flow chart of a conveyor line control method according to an embodiment of the present invention. The method includes steps S100 to S200, as shown in detail below:

[0081] S100: During the operation of the conveyor line, in response to receiving a first operation signal regarding a first production operation device sent by an operation control module, a first pallet conveying station is determined according to the first operation signal.

[0082] The first tray conveying station is the first tray conveying station located at the front side of the first production operation station in the tray conveying direction of the conveying line.

[0083] Specifically, in the embodiment of the present application, the first production operation device is a device that currently needs to perform production operation; the first production operation station is an operation area specially set for the first production operation device on the positioning conveying section, and the mover tray 300 needs to be accurately conveyed to the first production operation device for production operation; and the first tray conveying station is the first tray conveying station located at the front side of the first production operation station in the tray conveying direction of the conveying line.

[0084] In actual operation, the operation control module is used to control the production operation process of the plurality of production operation devices. When the operation control module confirms that the first production operation device can perform production operation, the operation control module sends a first operation signal to the first control module 130 to obtain the required materials or workpieces (placed on the mover tray). In the embodiment of the present application, the operation control module interacts with the first control module 130 and the second control module 230 to make the plurality of production operation devices and the conveying line composed of the non-positioning conveying section and the positioning conveying section constitute a production line in the factory workshop. The operation control module is a background device in the production line, which can directly control the plurality of production operation devices, but the control of the conveying line needs to be realized by interacting with the first control module 130 and the second control module 230. In the embodiment of the present application, the first control module 130 and the second control module 230 are the control modules that directly control the conveying line to operate.

[0085] In the embodiment of the present application, as shown in Figure 7 , Figure 7 The flow chart for determining the first tray conveying station in the conveying line control method provided by the embodiment of the present application, S100 includes: S101, details as shown below:

[0086] S101: The first control module determines the first tray conveying station according to the device identifier of the first production operation device included in the first operation signal.

[0087] Specifically, in the embodiment of the present application, as shown in Figure 8 , Figure 8A position schematic view of the first production work station and the first tray conveying station provided by the embodiment of the present application is shown in the figure. After the first control module 130 receives the first work signal, the first control module 130 analyzes the device identifier of the first production work device contained in the first work signal. According to the pre-stored correspondence between each conveying section in the conveying line and each production work device, the first control module 130 determines the first tray conveying station located at the front side of the first production work station, i.e., the first tray conveying station, along the predetermined tray conveying direction.

[0088] In actual operation, the plurality of tray conveying stations and the plurality of production work stations included in the conveying line each has a corresponding station number, and the plurality of production work devices each has a corresponding device number. The production work station corresponding to each production work device is stored in a corresponding form of station number and device number, as shown in Table 1. Table 1 is an example table of the correspondence between the station number and the device number provided by the embodiment of the present application. a1 in Table 1 represents the station number of the tray conveying station, b1 in Table 1 represents the station number of the production work station, M1 in Table 1 represents the device number of the production work device, and the current station state in Table 1 is used to indicate the working state of each station at the current time. The carrying state is the state of carrying the mover tray, and the empty state is the state of not carrying the mover tray. The column in Table 1 needs to be updated in real time.

[0089] Table 1: Example table of the correspondence between the station number and the device number

[0090]

[0091] According to Table 1, after the device number M1 of the first production work device is determined, the station number b1 of the first production work station corresponding to the device number M1 and the station number a7 of the first tray conveying station located at the front side of the first production work station, i.e., the station number a7 of the first tray conveying station, can be determined.

[0092] In one implementation manner, after S100, the method further includes S102-S104, which are shown in detail as follows:

[0093] S102: The first control module detects whether the first tray conveying station is in an empty state.

[0094] Specifically, in the embodiment of the present application, the first control module 130 can determine whether the corresponding tray conveying station is in an empty state according to the first magnetic drive encoder 123 arranged in each tray conveying station and update the above state in real time to Table 1.

[0095] S103: If it is determined that the first pallet conveying station is in an empty state, the first control module determines, among the multiple candidate pallet conveying stations, a pallet conveying station to be fed that is in a carrying state and has the shortest distance from the first production operation equipment.

[0096] Among them, the alternative pallet conveying station is the production operation station corresponding to the first production operation equipment located in front of the first production operation equipment, and is the pallet conveying station separated from the first production operation station corresponding to the first production operation equipment.

[0097] Specifically, in the embodiment of the present application, the alternative pallet conveying station is the production operation station corresponding to the first production operation equipment located in front of the first production operation equipment, and is the pallet conveying station separated from the first production operation station corresponding to the first production operation equipment.

[0098] For example, as shown in Table 1, if the production equipment with equipment number M3 is the first production equipment, then the production equipment with equipment number M2 is the "first production equipment located in front of the first production equipment", and the multiple material conveying stations corresponding to the station numbers a7~a12 are the alternative pallet conveying stations.

[0099] After determining a plurality of candidate pallet conveying stations, the first control module 130 determines a pallet conveying station to be fed that has the shortest distance from the first production equipment and is in a carrying state among the plurality of candidate pallet conveying stations.

[0100] For example, as shown in Table 1, among the multiple alternative pallet conveying stations corresponding to station numbers a7~a12, the pallet conveying station corresponding to station number a8 is the pallet conveying station with the smallest distance from the first production operation equipment and is in a transporting state. Therefore, the first control module 130 determines the pallet conveying station corresponding to station number a8 as the pallet conveying station to be fed.

[0101] S104: The first control module controls the non-positioning conveying section of the pallet conveying station to be fed, the multiple pallet conveying stations located between the pallet conveying station to be fed and the first pallet conveying station, and the first pallet conveying station to operate so as to transport the movable pallet carried by the pallet conveying station to be fed to the first pallet conveying station, so that the first pallet conveying station is in a carrying state.

[0102] Specifically, in an embodiment of the present application, after determining the pallet conveying station to be fed, the first control module 130 sequentially controls the pallet conveying station to be fed, the multiple pallet conveying stations located between the pallet conveying station to be fed and the first pallet conveying station, and the non-positioning conveying section where they are located operates to transport the movable pallet carried by the pallet conveying station to be fed to the first pallet conveying station, so that the first pallet conveying station is in a carrying state.

[0103] For example, as shown in Table 1, after determining the pallet conveying station for materials to be fed corresponding to the station number a8, the first control module 130 controls the non-positioning conveying section where the pallet conveying station for materials to be fed corresponding to the station number a8 is located and the non-positioning conveying section where multiple pallet conveying stations corresponding to the station numbers a9~a11 are located to operate, so as to transport the movable pallet carried by the pallet conveying station for materials to be fed corresponding to the station number a8 to the first pallet conveying station corresponding to the station number a12, so that the first pallet conveying station is in a carrying state.

[0104] S200: If it is determined that the first pallet conveying station is in a carrying state and the first production operation station is in an empty state, control the non-positioning conveying section where the first pallet conveying station is located to operate to transport the mover pallet to the first production operation station.

[0105] The carrying state refers to a state in which the mover pallet is carried; and the unloaded state refers to a state in which the mover pallet is not carried.

[0106] Specifically, in an embodiment of the present application, after determining that the first pallet conveying station is in the transporting state, the first control module 130 needs to interact with the second control module 230 to obtain the current station status of the first production operation station; the interaction can be achieved through a communication protocol (such as Ethernet, field bus, etc.) to ensure that the data between the two control modules can be transmitted in a timely and accurate manner.

[0107] In one implementation, Figure 9 As shown, Figure 9 This is a flow chart of transporting the mover pallet to the first production workstation in the conveyor line control method provided in an embodiment of the present application. S200 includes: S201 to S203, as detailed below:

[0108] S201: If the first pallet conveying station is in a carrying state, the first control module sends a first feeding request to the second control module.

[0109] Specifically, in the embodiment of the present application, when it is determined that the first tray conveying station is in the carrying state, a first feeding request is sent to the second control module 230 corresponding to the first production operation station to determine whether the first production operation station is in the empty state; if the first production operation station is in the carrying state, the mover tray cannot be conveyed to the first production operation station, otherwise, the mover trays will collide, thereby affecting the production operation.

[0110] S202: In response to the second control module detecting that the first production operation station is in the empty state, the second control module sends a first feeding permission signal to the first control module.

[0111] Specifically, in the embodiment of the present application, after the second control module 230 corresponding to the first production operation station receives the first feeding request, it is determined whether the first production operation station is in the empty state according to the second magnetic drive encoder 222 arranged in the first production operation station.

[0112] In actual operation, if the second control module determines that the first production operation station is in the carrying state at the current time through the second magnetic drive encoder 222, the second control module maintains the detection state through the second magnetic drive encoder 222 until it is determined that the first production operation station is in the carrying state through the second magnetic drive encoder 222. The second control module 230 sends a first feeding permission signal to the first control module 130.

[0113] S203: In response to receiving the first feeding permission signal, the first control module controls the non-positioning conveying section where the first tray conveying station is located to operate to convey the mover tray to the first production operation station.

[0114] Specifically, in the embodiment of the present application, after the first control module 130 receives the first feeding permission signal, it is determined that the first production operation station is in the empty state according to the first feeding permission signal. The first control module 130 controls the non-positioning conveying section where the first tray conveying station is located to operate to convey the mover tray 300 to the first production operation station.

[0115] In one implementation manner, as shown in Figure 10 , Figure 10 The flowchart for conveying the mover tray away from the second tray conveying station in the conveying line control method provided by the embodiment of the present application is shown as follows after S203: S204-S209, the details are shown as follows:

[0116] S204: In response to receiving the operation end signal, the second control module sends a second feeding request to the first control module.

[0117] Specifically, in an embodiment of the present application, when the first production operation equipment corresponding to the first production operation station completes the production operation in the first production operation station, the control operation equipment sends an operation completion signal to the second control module 230 to notify the second control module 230 that the production operation in the first production operation station has been completed.

[0118] After receiving the job end signal, the second control module 230 generates a second feeding request based on the job end signal and sends the second feeding request to the first control module 130, so as to request the first control module 130 to transport the second pallet conveying station in an empty state to transport the movable pallet to the second pallet conveying station in an empty state.

[0119] S205: In response to receiving the second feeding request sent by the second control module, the first control module determines the second pallet conveying station according to the equipment identification of the first production operation equipment included in the second feeding request.

[0120] Among them, the second pallet conveying station is the first pallet conveying station located at the rear side of the first production operation station.

[0121] Specifically, in an embodiment of the present application, when the first control module 130 receives the second feeding request, the first control module 130 parses the equipment identification of the first production operation equipment contained in the second feeding request; the first control module 130 determines the first pallet conveying station located behind the first production operation station along the established pallet conveying direction according to the correspondence between each conveying section and each production operation equipment in the pre-stored conveyor line, that is, the second pallet conveying station.

[0122] For example, as shown in Table 1, if the production operation equipment with equipment number M4 is the first production operation equipment, then the pallet conveying station with equipment number a7 is the "first pallet conveying station located behind the first production operation station", that is, the second pallet conveying station.

[0123] S206: The first control module detects whether the second pallet conveying station is in an empty state.

[0124] Specifically, in the embodiment of the present application, the first control module 130 can determine whether the corresponding pallet conveying station is in an empty state according to the first magnetic drive encoder 123 provided in each pallet conveying station and update the above state to Table 1 in real time.

[0125] S207: If it is determined that the second pallet conveying station is in a carrying state, the mover pallet carried by the second pallet conveying station is conveyed to a pallet conveying station that is located behind the first production operation station and is in an empty state.

[0126] Specifically, in an embodiment of the present application, if the first control module 130 determines that the second pallet conveying station is in a carrying state, the mover pallet 300 carried by the second pallet conveying station is transported to a pallet conveying station located behind the first production operation station and in an empty state.

[0127] For example, as shown in Table 1, if the production equipment with equipment number M4 is the first production equipment, then the pallet conveying station with station number a11 is the "pallet conveying station located behind the first production station and in an empty state."

[0128] S208: If it is determined that the second pallet conveying station is in an empty state, the first control module sends a second feeding permission signal to the second control module.

[0129] Specifically, in an embodiment of the present application, if the first control module 130 determines through the first magnetic drive encoder 123 that the second pallet conveying station is in a carrying state, the first control module 130 sends a second feed permission signal to the second control module 230 to notify the second control module 230 that the mover pallet can be transported to the second pallet conveying station.

[0130] S209: In response to receiving the second feed permission signal, the second control module controls the positioning and conveying section where the first production operation station is located to operate, so as to transport the mover pallet to the second pallet conveying station.

[0131] Specifically, in an embodiment of the present application, after receiving the second feed permission signal, the second control module 230 confirms that the second pallet conveying station is in an empty state according to the second feed permission signal, and the second control module 230 controls the positioning and conveying section where the first production operation station is located to operate to transport the mover pallet 300 to the second pallet conveying station.

[0132] It should be emphasized that the technical solutions mentioned above are steps implemented when each module or structure operates normally. However, in actual operation, faults may be encountered. For example, when the first control module 130 controls the compound motor group 120 in the pallet conveying station to operate, so that the compound motor group 120 drives the first roller 110 to rotate, and further drives the movable pallet 300 carried by it to move, but the first magnetic drive encoder 123 transmits the monitoring data of the movable pallet 300 to the first control module 130. The first control module 130 can determine that the pallet conveying station has a fault based on the monitoring data, and thus generates an early warning signal and sends the early warning signal to the operation control module.

[0133] Thirdly, the embodiment of the present application also provides a conveying line control method, which is applied to a target second control module in a plurality of second control modules 230 included in a conveying line control system; a plurality of production operation devices for performing production operations in different production operation stages are connected with the operation control module; the number of second production operation devices for performing production operations in a target production operation stage in the plurality of production operation stages is less than or equal to the number of production operation stations arranged in a target positioning conveying section corresponding to the target production operation stage; a tray conveying station is arranged on the positioning conveying section, and a production operation station is arranged on the positioning conveying section; as shown in Figure 11 Figure 11 The flowchart of another conveying line control method provided by the embodiment of the present application is shown, and the method comprises the following steps S300-S400:

[0134] S300: In the operation process of the conveying line, in response to receiving a target third feeding request sent by the first control module, target function information of the target second production operation station in the current production round is determined according to the target third feeding request.

[0135] The third feeding request is batch sent by the first control module to a plurality of second control modules corresponding to the target positioning conveying section; and the function information indicates the function assumed by the production operation station in the current production round.

[0136] Specifically, in the prior art, the operation time of the production operation device performing production operations in different production operation stages is usually different, for example, the operation time of the production operation device A is 3 min, and the operation time of the production operation device B is 5 min. Since the operation time of the production operation device A and the operation time of the production operation device B are different, the mover tray 300 transported after the production operation performed by the production operation device A will be stacked in the tray conveying station before the production operation station corresponding to the production operation device B, which further leads to low production efficiency. Therefore, the conveying line control system and the conveying line control method are provided to solve the above technical problems.

[0137] In detail, the idea of solving the above technical problems of the embodiment of the present application is to arrange a plurality of tray conveying stations in the non-positioning conveying section and a plurality of production operation stations in the positioning conveying section based on the provided non-positioning conveying section and positioning conveying section, and the plurality of production operation stations can be used for simultaneously performing production operations by the plurality of production operation devices for performing production operations in the same production operation stage, so as to balance the production operation efficiency of different production operation stages.

[0138] ​For example, the operating time of production equipment A is 3 minutes, and the operating time of production equipment B is 5 minutes. At this time, 3 production equipment A and 5 production equipment B are prepared. Within 15 minutes, the 3 production equipment A worked for 5 rounds, and each round performed production operations on 3 mover pallets 300 (1 production equipment performed production operations on 1 mover pallet 300 in 1 round). Therefore, within 15 minutes, the 3 production equipment A performed production operations on a total of 15 mover pallets 300; within 15 minutes, the 5 production equipment B worked for 3 rounds, and each round performed production operations on 5 mover pallets 300. Therefore, within 15 minutes, the 5 production equipment B performed production operations on a total of 15 mover pallets 300. Therefore, the production operation efficiency of the 3 production equipment A and the 5 production equipment B for the production operations on the mover pallets 300 within 15 minutes is the same.

[0139] In actual operation, although the above-mentioned production operation process can maximize the production operation efficiency, in many cases, the operation time may change, such as the shortening of the operation time due to the replacement of production operation equipment. In addition, when the number of production operation equipment increases or decreases, it may lead to the inability to drive the entire production line with the maximum production operation efficiency. Therefore, in the embodiment of the present application, a large number of production operation stations are usually pre-configured in the positioning and conveying section to prepare for the increase in the number of equipment due to the decrease in the production efficiency of the production operation equipment, and the increase or decrease in the number of equipment due to the innovation and replacement of the production operation equipment.

[0140] In actual operation, the number of production equipment performing production operations in different operation rounds may change due to changes in operation duration and other reasons. Therefore, it is necessary to determine the number and position of production equipment performing production operations in the current production round based on the actual production needs in the current production round (the actual production needs are usually determined by the operation control module). Accordingly, the number and position of production workstations used to carry the mover pallet 300 for the production equipment to perform production operations need to change accordingly.

[0141] To be specific, in the conveyor line control system provided in the embodiment of the present application, a positioning conveying section may include multiple production workstations and the multiple production workstations are not all used to carry the mover pallet 300 for the production operation equipment to perform production operations, that is, the multiple production operation stations included in the positioning conveying section may have different workstation functions; wherein, the types of workstation functions include: conveying function and operation function, the conveying function indicates that only the mover pallet 300 is conveyed, and the operation function indicates that the mover pallet 300 is carried for the production operation equipment to perform production operations.

[0142] For example, if the target positioning conveying section corresponding to the target production operation stage in the plurality of production operation stages includes 10 second production operation stations, but due to the adjustment of the production plan or the limitation of the number of production operation equipment, etc., only 6 second production operation stations are used to carry the mover tray 300 for production operation in the target production operation stage, at this time, in the 10 second production operation stations, only the station functions of the 6 second production operation stations are operation functions, and the station functions of the remaining 4 second production operation stations are conveying functions, at this time, the remaining 4 second production operation stations are equivalent to tray conveying stations in essence, which is the case that the number of production operation stations provided in the target positioning conveying section corresponding to the target production operation stage is greater than or equal to the number of second production operation equipment for production operation in the target production operation stage in the plurality of production operation stages.

[0143] According to the foregoing discussion, when the operation control module confirms that the first production operation equipment can perform production operation, the operation control module sends a first operation signal to the first control module 130.

[0144] According to the foregoing discussion, when the operation control module sends the first feeding signal to the first control module 130, the first control module 130 drives the non-positioning conveying section to operate to transport the mover tray 300 to the first production operation station in the positioning conveying section, according to the foregoing discussion, before driving the non-positioning conveying section to operate, the first control module 130 needs to send a feeding request to the second control module 230 to inquire whether the first production operation station corresponding to the second control module 230 is in an empty state, if it is in an empty state, the first control module 130 drives the non-positioning conveying section to operate.

[0145] In actual operation, if the positioning and conveying section includes multiple second production workstations, after the operation control module sends the second feeding signal to the first control module 130, the first control module 130 generates multiple third feeding requests according to the second feeding signal, and then sends the third feeding request to the second control module 230 corresponding to all the second production workstations included in the positioning and conveying section. However, the third feeding request sent is usually different because, in the embodiment of the present application, in order to improve the accuracy of transporting the mover pallet 300 to the production point where the production operation equipment can perform production operations, each second production operation station has They are controlled separately by their respective second control modules 230. Therefore, in order to make the second control modules 230 in each second production work station clear about the functions (i.e., functional information) of the second production work station corresponding to it in the current production round, it is usually necessary for the first control module 130 to send different third feeding requests to the second control modules 230 corresponding to each second production work station included in the positioning and conveying section, so as to inquire whether multiple second production work stations are in an unloaded state while informing the second control modules 230 of the functions of the second production work station corresponding to it in the current production round.

[0146] In actual operation, when the target second control module receives the third feeding request (one of multiple third feeding requests sent in batches) sent by the first control module 130, the target second control module parses the target function information of the target second production operation station in the current production round based on the third feeding request; the target second production operation unit is the second production operation station corresponding to the target second control module.

[0147] It should be emphasized that the description of the second control module 230 sending the first feed permission signal to the first control module 130 based on the first feed request has been discussed above. Here, after the target second control module receives the third feed request, if the target second control module determines that the corresponding second production workstation is in an unloaded state, the target second control module also needs to send a corresponding feed permission signal to the first control module 130. Since the above process has been discussed above, it will not be repeated here.

[0148] In one implementation, Figure 12 As shown, Figure 12 This is a flow chart of determining the target workstation function and target production sequence in the conveyor line control method provided in an embodiment of the present application. S300 includes: S301, details of which are as follows:

[0149] S301: Determine the target station function and target production sequence of the second production operation station in the current production round according to the target third material feeding request.

[0150] The type of the work station function includes a conveying function and a work function. The conveying function indicates only conveying the mobile sub-tray 300, and the work function indicates carrying the mobile sub-tray 300 for production work equipment to perform production work. The target production station sequence indicates, if the target work station function of the second production work station is the work function, the station sequence of the second production work station in at least one production work station for bearing the work function included in the target positioning conveying section.

[0151] Specifically, in the embodiment of the present application, as shown in Figure 13 , Figure 13 The position diagram of the second production work station in the conveying line control method provided by the embodiment of the present application is shown in Figure 13 5 second production work stations are arranged in the target positioning conveying section, but only 3 second production work stations have the work function, and the remaining 2 second production work stations only have the conveying function. The "target second production work station" is the second production work station corresponding to the target second control module in the embodiment of the present application.

[0152] According to Figure 13 , for one second production work station in the target positioning conveying section, each second production work station has the work function, but only the second production work station with the work function has the production station sequence. Taking the "target second production station sequence" as an example, in Figure 13 , of the 5 second production work stations shown in Figure 13 , 3 second production work stations have the work function, i.e., the 3rd and 5th from left to right. In the 3 second production work stations with the work function, the "target second production work station" is the first second production work station with the work function, so Figure 12 , the station sequence of the "target second production station sequence" is 2 / 3, which means that the "target second production station sequence" is the 2nd second production work station bearing the work function.

[0153] S400: According to the target function information, control the magnetic drive motor set in the target second production work station to operate, so that the target second production work station bears the function in the current production round.

[0154] Specifically, in the embodiment of the present application, when the target second control module determines the target function information, the magnetic drive motor set 220 in the target second production work station is controlled to operate to bear the work station function it should bear in the current production round.

[0155] In one implementation mode, the target positioning conveying section includes The second production station, , the target positioning conveying section is provided in the current production round The second production operation station with the function of the work station is the operation function. ;like Figure 14 As shown, Figure 14 This is a flow chart of transporting the mover pallet to the second production workstation in the conveyor line control method provided in an embodiment of the present application. S400 includes: S401, details of which are as follows:

[0156] S401: If the target station function is a conveying function, control the magnetic drive motor group in the target second production operation station to operate to sequentially receive at most Each mover tray is transported to the next second production operation station in turn, so that The mover pallets are transported to The second production workstation.

[0157] Specifically, in an embodiment of the present application, if the target station function of the target second production work station in the current production round is a conveying function, it only needs to interact with the first control module 130 in the first pallet conveying station located in front of it or the second control module 230 in the first second production work station located in front of it. The purpose of the interaction is that if it is determined that the target second production work station is in an unloaded state, the first pallet conveying station located in front of it or the second production work station located in front of it can transport the mover pallet 300 to the target second production work station, and the target second production work station can then transport the mover pallet 300 to the first pallet conveying station located on the rear side or the first second production work station located on the rear side; in actual operation, whenever the target second production work station needs to transport a mover pallet 300, the above process needs to be executed until the target non-positioning conveying section completes the function in the current production round.

[0158] In actual operation, due to the existence of the front side of the target second production operation station, there may be a second production operation station whose target station function in the current production round is an operation function. Therefore, before the multiple production operation equipment corresponding to the target positioning conveying section performs production operations, the target second production operation station sequentially receives "at most" The mover tray 300 is sequentially transported to the second production operation station behind it, that is, "sequentially transported to the next second production operation station so that The mover trays 300 are transported to second production workstations"; wherein, if the target second production workstation is the last second production workstation in the target positioning and conveying section, then before the multiple production operation equipment corresponding to the target positioning and conveying section perform production operations, the number of mover pallets 300 sequentially received by the target second production workstation is 0.

[0159] In one implementation, Figure 15 As shown, Figure 15 This is a flow chart of transporting the mover pallet to the production work station in the second production work station in the conveyor line control method provided in an embodiment of the present application. S400 also includes: S402 to S403, details of which are as follows:

[0160] S402: If the target station function is an operation function and the target production sequence is / , determine the number of conveying times for the second production workstation .

[0161] Among them, the target production sequence is Indicates the second production workstation included in the target positioning conveying section The first of the second production workstations used to undertake the operation function The second production workstation.

[0162] Specifically, in the embodiment of the present application, if the target station function is an operation function and the target station function is an operation function and the target production sequence is / , indicating that there is a - The workstation function is the second production workstation with the operation function. The target second production workstation has - The second production workstation with the function of the workstation is to make the back of the second production workstation - The second production operation station with the operation function of each station has received the mover tray 300, and the target second production operation station needs to transport - 300 mover trays to the rear - The function of each workstation is the second production workstation with an operation function.

[0163] It should be emphasized that although the format of the target production sequence is " ", but it is only for the convenience of explaining the constructed format. In actual operation, the actual format of the message in which the second control module 230 interacts with other control modules can be determined according to actual needs. It is only necessary to make the target second control module clear about "the second production operation station included in the target positioning and conveying section". The first of the second production workstations used to undertake the operation function A second production operation station" is sufficient, and this application does not make any specific limitation on this.

[0164] S403: According to the number of delivery times Control the magnetic drive motor group in the second production operation station to operate to The mover pallet is transported to the next second production operation station in turn, and the received The mover pallet is transported to the production operation position in the second production operation station.

[0165] The production operation site represents that when the mover pallet 300 is located at the production operation site, the production operation equipment can perform production operations based on the mover pallet 300.

[0166] Specifically, in the embodiment of the present application, the target second control module specifies the number of delivery times. The purpose is to facilitate the counting of the transported mover pallet 300. If the target second production operation station has transported After the mover pallet 300 is delivered, the target second control module still receives a feeding request from the first control module 130 in the first pallet conveying station located in front of it or the second control module 230 in the first second production operation station located in front of it, requesting that the mover pallet 300 be delivered to it again. The target second control module can generate an early warning signal, which can be sent to the first control module 130 or to the operation control module.
