Description

Technical Field

[0001] The invention relates to the technical field of automated roller conveyor lines for in-factory logistics, and in particular to an electrical system and a control method for high-speed stopper equipment for high-speed roller conveyor lines. Background Art

[0002] The stopper is a device used to assist in controlling the stopping position of the goods being transported on the conveyor line. When the turnover box is transported at high speed on the conveyor line, the inertia is large. If the box is stopped normally, the stopping position will be different depending on the weight of the goods loaded in the turnover box. Some turnover boxes need to be stopped accurately at the specified position of the conveyor line. For example, there are positions with transfer machines on the conveyor line. The turnover box needs to be stopped accurately, so the stopper device is needed. When the turnover box in high-speed transportation needs to be stopped accurately at the accumulation station, the stopper is needed to assist the turnover box to stop.

[0003] The power source of the stopper used in the existing project is the cylinder. At present, the factory with a high safety level does not install the air source in the factory for safety considerations, and does not allow the use of air pumps in the factory, so the stopper cannot be used without a power source. When the air source can be used, the lifting speed and action rhythm transition of the stopper depend on the stability of the air source pressure. The control method of the stopper cannot meet the requirements of high-speed conveyor lines, which is not conducive to accurately controlling the action of the stopper during high-speed transportation.

[0004] Most existing warehouse conveying equipment manufacturers have few high-speed conveyor projects. The use scenario of the stopper is used on non-high-speed conveyors. The control method can be used during non-high-speed conveying. The use of cylinders as a power source is low-cost and easy to maintain. The conveying rhythm during high-speed conveying is fast, and the stopper needs to run at high speed. At this time, the stopper with cylinders as power is used. The stopper action rhythm is slow and the stability cannot be guaranteed. The control method cannot meet the application of the stopper on high-speed conveyor lines. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention proposes a control method and control system for goods-to-person picking station equipment to solve the problem of slow and unstable cycle when the stopper is used on a high-speed conveyor line. The technical solution of the present invention replaces a power source with a faster and more stable cycle, and designs an electrical solution for this purpose, which can control the stopper and is convenient for wiring and debugging.

[0006] In order to solve the above technical problems, the specific technical solutions of the present invention are as follows:

[0007] In a first aspect, the present invention provides an electrical system for a high-speed stopper device for a high-speed roller conveyor line, comprising:

[0008] Used for the electrical system of high-speed roller conveyor line high-speed stopper equipment, characterized by including: controller, ASI gateway, ASI electric roller drive module, upper limit proximity switch, lower limit proximity switch, DC brushless motor drive, DC brushless motor driver and stopper DC brushless motor;

[0009] The controller establishes a communication connection with the ASI gateway. The ASI gateway is connected to the distributed ASI electric roller drive module through the ASI bus. The ASI electric roller drive module is connected to the upper limit proximity switch and the lower limit proximity switch, and receives the DC brushless motor driver fault signal. The DC brushless motor driver fault signal is input to the ASI electric roller drive module through the roller fault input signal of the ASI electric roller drive module. The ASI electric roller drive module outputs a start signal and a direction signal to control the DC brushless motor driver, which is used to make the DC brushless motor rotate forward and reverse, thereby driving the stopper baffle to move up and down;

[0010] The controller includes:

[0011] A data acquisition unit, which acquires the stopper device information and the stopper installation position information;

[0012] The control measurement matching unit matches the installation position information of the stopper in a preset control strategy knowledge base to obtain the control strategy corresponding to the installation position of the stopper. The control strategy knowledge base includes the control strategy of the stopper with the straight line section, the control strategy of the stopper with the transfer machine out-of-box section, the control strategy of the stopper with the transfer machine in-box section, and the control strategy of the stopper with the swing wheel machine out-of-box section;

[0013] Control command conversion, initializing the stopper so that the stopper drops to the lower limit position, and converting the control strategy corresponding to the installation position of the stopper into control information;

[0014] The control command execution unit sends control information to the DC brushless motor driver of the stopper. The control information includes a start signal and a direction signal. The start signal and the direction signal control the DC brushless motor driver of the stopper to make the DC brushless motor rotate forward and reverse, thereby driving the stopper baffle to move up and down.

[0015] Furthermore, the electrical system of the high-speed stopper equipment for the high-speed roller conveyor line of the present invention, the stopper is matched with the straight line segment control strategy, including:

[0016] After the stopper control starts, it is initialized first, and the stopper drops to the lower limit position to determine the wave of the upper computer controlling the straight line segment. If it is a wave collection control, it is determined whether the station is unloading. If not, the stopper rises to the upper limit position. If the station is unloading, the turnover box leaves the station for accumulation and arrives at the next station for accumulation. The stopper rises to the upper limit position, and then after the station completes the box loading and touches the stopper calibration position, the stopper is detected to be in the raised state, then the station stops unloading and the wave collection is completed. If it is a release wave, the upper computer controls the stopper to release the wave. After the stopper drops to the lower limit position, the station accumulation detects that the stopper has been lowered, then the turnover box of the station is unloaded, the release wave control is completed, and the stopper and straight line segment control end.

[0017] Furthermore, the electrical system of the high-speed stopper equipment for the high-speed roller conveyor line of the present invention, the control strategy of the stopper and the box-out section of the transfer machine, includes:

[0018] After the control of the transfer section out-box stopper starts, it is initialized first, and the stopper drops to the lower limit position. The turnover box at the previous station is out, and the transfer section of this station accumulates and moves straight to move the box in. The host computer command is retrieved to determine whether the turnover box is transported to the transfer and out-box straight section for accumulation. If not, it is determined whether the accumulation section of the next station is allowed to enter the box. Under the condition that the box is allowed to enter, the turnover box of this station is out to the next station. If the turnover box needs to be transported to the transfer and out-box straight section for accumulation, the stopper rises to the upper limit position. After the turnover box of this station is in place, it touches the stopper calibration position. It is determined whether the accumulation section of the transfer and out-box is allowed to enter. If the box is allowed to enter, the transfer and out-box is moved to the transfer and out-box straight section. Then the stopper drops to the lower limit position, and the stopper and the transfer section out-box control are completed.

[0019] Furthermore, the electrical system of the high-speed stopper equipment for the high-speed roller conveyor line of the present invention, the control strategy of the stopper and the transfer machine box feeding section includes:

[0020] After the control of the box feeding section of the transfer machine starts, the stopper is initialized first, the left stopper is lowered to the lower limit position, and the right stopper is lowered to the upper limit position;

[0021] Determine the direction of the transfer machine feeding the box. If it is a straight-line feeding, after the turnover box of this station is in place, determine whether the next station accumulation section allows the box to enter. If the box is allowed to enter, the turnover box of this station will be unloaded to the next station for accumulation;

[0022] If it is a left box transfer, the left stopper will drop to the lower limit position. After the right stopper rises to the upper limit position, it is determined whether the left stopper has dropped to the lower limit position. After the left stopper has dropped into place, the turnover box is transported from the left box transfer straight section to this station for accumulation. After it hits the baffle of the right stopper, the position is calibrated. After the turnover box of this station is in place, the left and right stoppers will both drop to the lower limit position. After both drop to the lower limit position, it is determined whether the accumulation section of the next station allows the box to enter. If the box is allowed to enter, the turnover box of this station will be transported to the next station for accumulation.

[0023] If it is a right box transfer, the right stopper will drop to the lower limit, and after the left stopper rises to the upper limit, it is determined whether the right stopper has dropped to the lower limit. After the right stopper has dropped into place, the turnover box is transported from the right box transfer straight section to this station for accumulation. The turnover box hits the left stopper baffle and calibrates the position. After the turnover box at this station is in place, the left and right stops will both drop to the lower limit. After both drop to the lower limit, it is determined whether the next station accumulation section allows the box to enter. If the turnover box is allowed to enter, the turnover box at this station will be transported to the next station for accumulation, and the stopper and the transfer machine section box entry control are completed.

[0024] Furthermore, the electrical system of the high-speed stopper equipment for the high-speed roller conveyor line of the present invention, the control strategy of the stopper and the oscillating wheel machine out-of-box section includes:

[0025] After the stopper is matched with the pendulum machine for box discharge control, it is initialized first, the pendulum machine turns to the straight direction, the stopper drops to the lower limit, the turnover box at the previous station is discharged, and the transfer section of this station accumulates and enters the box in a straight line. The host computer command is retrieved to determine whether the turnover box is transported to the pendulum machine out of the straight line section for accumulation. If not, it is determined whether the accumulation section of the next station is allowed to enter the box. Under the condition that the box is allowed to enter, after the pendulum machine turns to the straight-line discharge direction, the turnover box of this station is discharged to the next station. If the turnover box needs to be transported to the pendulum machine out of the straight line section for accumulation, the stopper rises to the upper limit. After the turnover box of this station is in place, it touches the stopper calibration position, and the pendulum machine turns to the balance wheel branch out of the box direction to determine whether the balance wheel branch out of the box section accumulation allows the box to enter. If the box is allowed, the pendulum machine of this station discharges the box to the balance wheel machine branch out of the straight line section, and then the stopper drops to the lower limit, and the stopper combined with the pendulum machine section out of the box control ends.

[0026] In a second aspect, the present invention provides a control method for a high-speed roller conveyor line high-speed stopper device, which is applied to the electrical system of the high-speed roller conveyor line high-speed stopper device, comprising:

[0027] Step S101, obtaining the stopper device information and the stopper installation position information;

[0028] Step S102, matching the stopper installation position information in a preset control strategy knowledge base to obtain a control strategy corresponding to the stopper installation position, the control strategy knowledge base includes a control strategy for a stopper with a straight line segment, a control strategy for a stopper with a transfer machine out-of-box segment, a control strategy for a stopper with a transfer machine in-box segment, and a control strategy for a stopper with a pendulum machine out-of-box segment;

[0029] Step S103, initializing the stopper so that the stopper descends to the lower limit position, and converting the control strategy corresponding to the installation position of the stopper into control information;

[0030] Step S104, sending control information to the DC brushless motor driver of the stopper, the control information including a start signal and a direction signal, the start signal and the direction signal control the DC brushless motor driver of the stopper, and are used to make the DC brushless motor rotate forward and reverse, thereby driving the stopper baffle to move up and down.

[0031] Furthermore, the high-speed stopper device control method for a high-speed roller conveyor line according to the present invention, the step S102 comprises:

[0032] The control strategy of the stopper combined with the straight line segment includes initialization after the stopper control starts, the stopper drops to the lower limit, and the wave of the upper computer controlling the straight line segment is determined. If it is a wave collection control, it is determined whether the station is unloading. If not, the stopper rises to the upper limit. If the station is unloading, the turnover box leaves the station for accumulation and arrives at the next station for accumulation. The stopper rises to the upper limit, and then after the station completes the box loading and touches the stopper calibration position, the stopper is detected to be in the raised state, then the station stops unloading, and the wave collection is completed. If it is a release wave, the upper computer controls the stopper to release the wave. After the stopper drops to the lower limit, the station accumulation detects that the stopper has completed its descent, then the station turnover box is unloaded, the release wave control is completed, and the stopper combined with the straight line segment control ends.

[0033] Furthermore, the high-speed stopper device control method for a high-speed roller conveyor line according to the present invention, the step S102 comprises:

[0034] The control strategy of the stopper combined with the transfer machine outbound section includes initialization after the control of the stopper of the transfer section outbound section starts, the stopper drops to the lower limit position, the turnover box is discharged from the previous station, the transfer section of this station accumulates and moves straight into the box, retrieves the host computer instruction, and determines whether the turnover box is transported to the transfer and outbound straight section for accumulation. If not, it determines whether the accumulation section of the next station allows the box to enter. Under the condition that the box is allowed to enter, the turnover box of this station is discharged to the next station. If the turnover box needs to be transported to the transfer and outbound straight section for accumulation, the stopper rises to the upper limit position, and the turnover box of this station touches the stopper calibration position after it is in place. It is determined whether the transfer and outbound section accumulation allows the box to enter. If the box is allowed, the transfer and outbound box of this station is transferred to the transfer and outbound straight section, and then the stopper drops to the lower limit position, and the outbound control of the stopper combined with the transfer machine section ends.

[0035] Furthermore, the high-speed stopper device control method for a high-speed roller conveyor line according to the present invention, the step S102 comprises:

[0036] The control strategy of the stopper and transfer machine box feeding section includes: after the control of the stopper and transfer machine box feeding section starts, it is initialized first, the left stopper is lowered to the lower limit position, and the right stopper is lowered to the upper limit position;

[0037] Determine the direction of the transfer machine feeding the box. If it is a straight-line feeding, after the turnover box of this station is in place, determine whether the next station accumulation section allows the box to enter. If the box is allowed to enter, the turnover box of this station will be unloaded to the next station for accumulation;

[0038] If it is a left box transfer, the left stopper will drop to the lower limit position. After the right stopper rises to the upper limit position, it is determined whether the left stopper has dropped to the lower limit position. After the left stopper has dropped into place, the turnover box is transported from the left box transfer straight section to this station for accumulation. After it hits the baffle of the right stopper, the position is calibrated. After the turnover box of this station is in place, the left and right stoppers will both drop to the lower limit position. After both drop to the lower limit position, it is determined whether the accumulation section of the next station allows the box to enter. If the box is allowed to enter, the turnover box of this station will be transported to the next station for accumulation.

[0039] If it is a right box transfer, the right stopper will drop to the lower limit, and after the left stopper rises to the upper limit, it is determined whether the right stopper has dropped to the lower limit. After the right stopper has dropped into place, the turnover box is transported from the right box transfer straight section to this station for accumulation. The turnover box hits the left stopper baffle and calibrates the position. After the turnover box at this station is in place, the left and right stops will both drop to the lower limit. After both drop to the lower limit, it is determined whether the next station accumulation section allows the box to enter. If the turnover box is allowed to enter, the turnover box at this station will be transported to the next station for accumulation, and the stopper and the transfer machine section box entry control are completed.

[0040] Furthermore, the high-speed stopper device control method for a high-speed roller conveyor line according to the present invention, the step S102 comprises:

[0041] The control strategy of the stopper and the pendulum machine out-box section includes: the stopper and the pendulum machine out-box control are initialized first after starting, the pendulum machine turns to the straight direction, the stopper drops to the lower limit, the turnover box of the previous station is out, the transfer section of this station accumulates and enters the box straightly, retrieves the host computer instruction, and determines whether the turnover box is transported to the pendulum machine out-box straight section for accumulation. If not, it determines whether the accumulation section of the next station allows the box to enter. Under the condition that the box is allowed to enter, the pendulum machine turns to the straight out-box direction. After that, the turnover box of this station is unloaded to the next station. If the turnover box needs to be transported to the straight section of the pendulum machine for accumulation, the stopper rises to the upper limit position. After the turnover box of this station is in place, it touches the calibration position of the stopper, and the pendulum machine turns to the direction of the balance wheel branch outbound box to determine whether the balance wheel branch outbound box section accumulation allows the box to enter. If the box is allowed to enter, the pendulum machine of this station will unload the box to the straight section of the pendulum machine branch outbound box, and then the stopper will drop to the lower limit position, and the stopper and the pendulum machine section outbound box control will end.

[0042] The beneficial effects of the present invention are as follows:

[0043] The present invention adopts a brushless DC motor as the power source of the stopper. Compared with the traditional cylinder drive method, it has a faster response speed and higher stability. It can enable the stopper to perform actions accurately and quickly on a high-speed conveyor line, thereby improving the operating efficiency of the entire conveyor line.

[0044] The present invention includes optimized control strategies for different conveyor line scenarios through a preset control strategy knowledge base. The strategies can be flexibly matched and executed according to the installation position and specific needs of the stopper, thereby enhancing the flexibility and adaptability of the system, enabling the system to cope with conveyor lines with different layouts and operating requirements and improving the utilization rate of the equipment.

[0045] The present invention monitors the position of the stopper in real time through the upper limit proximity switch and the lower limit proximity switch, so that the stopper is always in the correct position during the action process. At the same time, the DC brushless motor driver can feed back the fault signal to the control system in time, so that the system can detect and handle the fault in time, thereby improving the reliability and stability of the system.

[0046] The present invention realizes precise control of the stopper through a sophisticated control strategy and an efficient electrical system, which can reduce production delays or downtime caused by inaccurate or unstable stopper action, thereby improving the overall operating efficiency of the conveyor line.

[0047] The brushless DC motor used in the present invention has a long service life and low maintenance cost. At the same time, due to the improvement of system stability and accuracy, the downtime and maintenance time caused by failures are reduced, further reducing the operating cost.

Through the precise electrical system and control method, intelligent control of the stopper is achieved, the need for manual intervention is reduced, and the automation and intelligence level of the production line are improved.

[0049] To summarize, the present invention effectively solves the problems of slow rhythm and instability of the stopper applied on the high-speed conveyor line by replacing the power source, designing a special electrical system and control method, presetting the control strategy knowledge base, and real-time monitoring and feedback, thereby improving the overall operating efficiency and stability of the conveyor line, reducing maintenance and operating costs, and improving the level of automation.

[0060] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The technical solutions provided by the embodiments of the present invention are described in detail below in conjunction with the drawings.

[0061] In order to better understand the purpose of the present invention, the present invention is described in further detail below.

[0062] In a first aspect, the present invention provides an electrical system for a high-speed stopper device for a high-speed roller conveyor line, comprising:

[0063] Used for the electrical system of high-speed roller conveyor line high-speed stopper equipment, characterized by including: controller, ASI gateway, ASI electric roller drive module, upper limit proximity switch, lower limit proximity switch, DC brushless motor drive, DC brushless motor driver and stopper DC brushless motor;

[0064] like Figure 1 As shown, the controller establishes a communication connection with the ASI gateway, the ASI gateway is connected to the distributed ASI electric roller drive module through the ASI bus, the ASI electric roller drive module is connected to the upper limit proximity switch and the lower limit proximity switch, and receives the DC brushless motor driver fault signal, the DC brushless motor driver fault signal is sent to the ASI electric roller drive module through the roller fault input signal of the ASI electric roller drive module, and the ASI electric roller drive module outputs a start signal and a direction signal to control the DC brushless motor driver, which is used to make the DC brushless motor rotate forward and reverse, thereby driving the stopper baffle to move up and down;

[0065] The communication connection between the invention controller and the ASI gateway establishes an information transmission channel to realize the control of the stopper on the high-speed roller conveyor line. The following is a detailed analysis of this connection and its subsequent functions:

[0066] As the "brain" of the entire electrical system, the controller is responsible for receiving instructions, processing data and issuing control signals.

[0067] As a communication interface, the ASI gateway converts the controller's signal into the ASI bus protocol, allowing the signal to be stably transmitted in a complex industrial environment. The communication connection enables the controller to obtain the status information of the stopper in real time and issue control instructions as needed.

[0068] Connection between ASI bus and distributed ASI electric roller drive modules: ASI bus is a communication protocol specially used in the field of industrial automation, which is characterized by high speed and reliability. Distributed ASI electric roller drive modules are distributed along the conveyor line, and each module is responsible for controlling the electric rollers in a certain area. Through the ASI bus, the controller can communicate with multiple electric roller drive modules at the same time to achieve centralized control of the entire conveyor line.

[0069] Connection between ASI electric roller drive module, proximity switch and DC brushless motor driver: The upper limit proximity switch and the lower limit proximity switch are used to detect the position of the stopper so that the stopper will not exceed the preset range during movement. The DC brushless motor driver is responsible for controlling the forward and reverse rotation of the DC brushless motor, thereby driving the stopper baffle to move up and down. The ASI electric roller drive module receives the position signal from the proximity switch and the fault signal from the DC brushless motor driver, and outputs the start signal and direction signal to the DC brushless motor driver based on these signals.

[0070] If the BLDC motor driver fails, it immediately sends a fault signal to the ASI drum drive module.

[0071] After receiving the fault signal, the ASI electric roller drive module can feed back the fault information to the controller through the ASI bus. The controller takes corresponding measures according to the fault information, such as stopping the current operation, issuing an alarm, etc., to ensure the safe and stable operation of the system.

[0072] In summary, the communication connection established between the controller and the ASI gateway and its subsequent functional design provide reliable technical support for the precise control of the stopper on the high-speed roller conveyor line. Through this design, the system can obtain the status information of the stopper in real time, issue precise control instructions as needed, and realize timely detection and processing of faults.

[0073] The controller includes:

[0074] A data acquisition unit, which acquires the stopper device information and the stopper installation position information;

[0075] In the present invention, the data acquisition unit is responsible for acquiring the stopper device information and the stopper installation position information, which are the basis for the subsequent control strategy formulation and execution.

[0076] The specific functions of the data acquisition unit include but are not limited to the basic parameters of the stopper such as model, size, weight, maximum bearing capacity, and movement speed. The parameters are crucial to understanding the performance limit of the stopper and making it operate within a safe range.

[0077] Get the stopper installation position information: The installation position information describes in detail the specific position of the stopper on the conveyor line, including the position relationship of the stopper relative to other conveyor line components (such as electric rollers, transfer machines, swing wheels, etc.), as well as the information of the specific accumulation section or workstation served by the stopper.

[0078] Accurate installation position information is essential for developing appropriate control strategies. For example, if the stopper is located in the straight section, the transfer machine out-box section, the transfer machine in-box section, or the swing wheel machine out-box section, different control strategies are required to ensure smooth operation of the conveyor line.

[0079] Provide a basis for the formulation of control strategies: By obtaining the device information and installation location information of the stopper, the controller can identify the specific environment and working requirements of the stopper, so as to select or formulate the most appropriate control strategy.

[0080] Improve system flexibility and adaptability: In different conveyor line layouts and operating scenarios, the installation location and control requirements of the stopper will be different. The data acquisition unit can capture this information in real time, allowing the system to flexibly adjust the control strategy to adapt to different work requirements.

[0081] Improve the stable operation of the system: Accurate equipment information and location information are the prerequisites for the normal operation of the stopper. By continuously monitoring and updating this information, the system can promptly detect and correct potential problems, thereby ensuring the stable operation of the conveyor line.

[0082] In summary, the data acquisition unit plays an indispensable role in the present invention. The data acquisition unit provides a solid foundation for the formulation and execution of the control strategy by acquiring the stopper device information and installation position information.

[0083] The control measurement matching unit matches the installation position information of the stopper in a preset control strategy knowledge base to obtain the control strategy corresponding to the installation position of the stopper. The control strategy knowledge base includes the control strategy of the stopper with the straight line section, the control strategy of the stopper with the transfer machine out-of-box section, the control strategy of the stopper with the transfer machine in-box section, and the control strategy of the stopper with the swing wheel machine out-of-box section;

[0084] The main function of the control measurement matching unit is to match the obtained stopper installation position information in a preset control strategy knowledge base, so as to determine the control strategy corresponding to the stopper installation position.

[0085] The working process of the control measurement matching unit is as follows: the control measurement matching unit first receives the stopper installation position information provided by the data acquisition unit, and the information describes in detail the specific position of the stopper on the conveyor line and its operating environment.

[0086] Knowledge base matching: The control measurement matching unit matches these position information with the preset control strategy knowledge base. The knowledge base contains a variety of control strategies for different scenarios and needs, such as the control strategy of the stopper with the straight line section, the control strategy of the stopper with the transfer machine out of the box section, the control strategy of the stopper with the transfer machine in the box section, and the control strategy of the stopper with the swing wheel machine out of the box section.

[0087] The control strategy is carefully designed according to the different layouts of the conveyor line, the operation process and the functional requirements of the stopper, so that the stopper can perform its tasks accurately and efficiently in various scenarios. After matching, the control measurement matching unit will output the control strategy corresponding to the installation position of the stopper. The strategy will serve as the basis for the subsequent control command conversion and execution, so that the stopper can act in a predetermined manner and rhythm.

[0088] Stopper combined with straight section control strategy: For the situation where the stopper is installed in the straight section accumulation area, a series of control strategies are designed to ensure the accurate parking and smooth transportation of the turnover box on the straight section.

[0089] Control strategy for the box-outgoing section when the stopper is used in conjunction with the transfer machine: For the scenario where the stopper is used in conjunction with the transfer machine to transport turnover boxes in the box-outgoing section, a corresponding control strategy is formulated to coordinate the actions of the transfer machine and the stopper to improve the box-outgoing efficiency.

[0090] Control strategy of the box-input section with the stopper and the transfer machine: Similar to the box-out section, the control strategy of the box-input section is also aimed at optimizing the coordination between the transfer machine and the stopper so that the turnover box can enter the designated position accurately and quickly.

[0091] The control strategy of the stopper combined with the pendulum machine out-of-box section: In view of the special needs of the pendulum machine out-of-box section, a special control strategy is designed to cope with complex actions such as the pendulum machine's steering and branch out-of-box, so as to ensure the overall smoothness of the conveyor line.

[0092] By controlling the coordination of the measurement matching unit and the preset control strategy knowledge base, the present invention can achieve precise control of the high-speed stopper of the high-speed roller conveyor line, meet the operation requirements in different scenarios, and improve the overall operation efficiency and stability of the conveyor line.

[0093] Control command conversion, initializing the stopper so that the stopper drops to the lower limit position, and converting the control strategy corresponding to the installation position of the stopper into control information;

[0094] The control command conversion module plays a bridging role in the electrical system of the high-speed roller conveyor line high-speed stopper equipment. It is responsible for converting the control strategy output by the control measurement matching unit into specific control information so that the execution unit can accurately control the action of the stopper. The following is the specific workflow and importance of the control command conversion module:

[0095] Stopper initialization: At the beginning of the control command conversion, the stopper will be initialized first, which usually means lowering the stopper to the lower limit of its mechanical structure so that the stopper is in a known and safe starting state.

[0096] Control strategy analysis: Next, the control command conversion module will analyze the control strategy output by the control measurement matching unit. The strategy is formulated according to the installation position of the stopper and the specific needs of the conveyor line, aiming to optimize the action sequence and timing of the stopper.

[0097] Control information generation: After parsing the control strategy, the control command conversion module will generate corresponding control information according to the specific requirements of the strategy. The control information usually includes start signals, direction signals, speed instructions, etc., which will directly guide the action of the stopper.

[0098] Information transmission: Finally, the control command conversion module will send the generated control information to the execution unit of the stopper (such as a brushless DC motor driver) to drive the stopper to act according to a predetermined strategy.

[0099] Improve the accuracy of the action: By converting the control strategy into specific control information, the control command conversion module can make the action of the stopper consistent with the overall requirements of the conveyor line, thereby improving the accuracy of the action.

[0100] Improve system flexibility: Since the control strategy is pre-set and can be adjusted according to actual needs, the control command conversion module can flexibly respond to different operating scenarios and needs, improving the adaptability and flexibility of the entire system.

[0101] Enhanced system stability: Through precise control command conversion, the system can more effectively manage the movement of the stopper, reduce failures and downtime caused by misoperation or improper movement, thereby enhancing the stability and reliability of the system.

[0102] In summary, the control command conversion module plays a vital role in the electrical system of the high-speed roller conveyor line high-speed stopper equipment. It analyzes the control strategy and generates corresponding control information, so that the stopper can perform actions accurately and efficiently in a predetermined manner, providing a strong guarantee for the smooth operation of the entire conveyor line.

[0103] The control command execution unit sends control information to the DC brushless motor driver of the stopper. The control information includes a start signal and a direction signal. The start signal and the direction signal control the DC brushless motor driver of the stopper to make the DC brushless motor rotate forward and reverse, thereby driving the stopper baffle to move up and down.

[0104] The control command execution unit plays a core role in the electrical system of the high-speed roller conveyor line high-speed stopper equipment. It is responsible for accurately sending the control information generated by the control command conversion module to the DC brushless motor driver of the stopper, thereby controlling the movement of the stopper. The following are the specific functions and importance of the control command execution unit:

[0105] The control command execution unit first receives the control information from the control command conversion module, which includes the start signal, direction signal, etc., which describe in detail how the stopper should act. After receiving the information, the control command execution unit will analyze the information and accurately understand the control intention.

[0106] After parsing the control information, the control command execution unit sends these signals to the DC brushless motor driver of the stopper. The DC brushless motor driver is a key device for controlling the movement of the stopper. It controls the forward and reverse rotation of the DC brushless motor according to the received signals.

[0107] The start signal is used to activate the motor driver to prepare it for action; the direction signal determines the direction of rotation of the motor, thereby controlling the rise or fall of the stopper baffle.

[0108] While sending the signal, the control command execution unit also monitors the execution of the DC brushless motor driver, so that the stopper can move accurately according to the predetermined strategy.

[0109] If an abnormality or failure occurs during the execution process, the control command execution unit will respond in a timely manner, including stopping the current action, issuing an alarm, or performing other error handling operations.

[0110] The control command execution unit is the last step in the realization of the control strategy, which directly controls the movement of the stopper. If the execution unit fails or makes a mistake, the entire control process will not achieve the expected effect.

[0111] Since the control command execution unit is directly connected to the drive device of the stopper, it can respond to the control command quickly, so that the stopper can complete the action in the shortest time, which is crucial to improving the overall operation efficiency of the conveyor line.

[0112] Through strict signal transmission and monitoring mechanism, the control command execution unit can ensure the accuracy and stability of the stopper action. At the same time, it also has error handling capabilities, which can reduce the system failure rate to a certain extent and improve the overall reliability of the system.

[0113] In summary, the control command execution unit is an indispensable part of the electrical system of the high-speed roller conveyor line high-speed stopper equipment. It accurately receives, analyzes and executes control information, enabling the stopper to operate efficiently and stably according to the predetermined strategy, providing a strong guarantee for the smooth operation of the conveyor line.

[0114] Specifically, the electrical system of the high-speed stopper equipment for the high-speed roller conveyor line of the present invention, the stopper is matched with the straight line segment control strategy, including:

[0115] After the stopper control starts, it is initialized first, and the stopper drops to the lower limit position to determine the wave of the upper computer controlling the straight line segment. If it is a wave collection control, it is determined whether the station is unloading. If not, the stopper rises to the upper limit position. If the station is unloading, the turnover box leaves the station for accumulation and arrives at the next station for accumulation. The stopper rises to the upper limit position, and then after the station completes the box loading and touches the stopper calibration position, the stopper is detected to be in the raised state, then the station stops unloading and the wave collection is completed. If it is a release wave, the upper computer controls the stopper to release the wave. After the stopper drops to the lower limit position, the station accumulation detects that the stopper has been lowered, then the turnover box of the station is unloaded, the release wave control is completed, and the stopper and straight line segment control end.

[0116] In high-speed roller conveyor lines, the control strategy of the stopper and the straight section is the key to ensure that the goods can stop accurately and flow smoothly during the conveying process. Specifically, the control strategy includes the following steps:

[0117] When the stopper control starts, an initialization operation is first performed, which means that the stopper is lowered to the lower limit of its mechanical structure, so that it is in a known and safe starting state.

[0118] Next, the system will determine the control wave of the upper computer on the straight line segment. Wave control is a scheduling method commonly used in logistics automation to optimize the order of goods in and out of the box.

[0119] If the current setting is "collection wave control", the system will further check whether the accumulation area at this station (i.e. the goods storage area at the current workstation) is being unpacked.

[0120] Wave control: Under wave control, if the stacking station is not in the state of unloading, the stopper will immediately rise to the upper limit to prepare for the next loading operation. If the stacking station is unloading, the system will wait for the turnover box (box loaded with goods) to leave the stacking station and arrive at the next stacking station before raising the stopper to the upper limit.

[0121] When the box loading operation of this station is completed, the turnover box will hit the calibration position of the stopper. At this time, the system will detect the raised state of the stopper and stop the box loading operation of this station, and the wave control is completed.

[0122] Release wave control. If the current setting is "Release wave control", the upper computer sends a command to control the stopper to release the wave operation. The stopper will drop to the lower limit to make room for the goods to be unpacked. After the station stacking detects that the stopper has dropped, it will allow the turnover box to be unpacked, and the release wave control is completed.

[0123] The control ends, no matter it is the collection wave control or the release wave control, after completing the corresponding operation, the control strategy of the stopper with the straight line segment ends.

[0124] Through this control strategy, the system can flexibly adjust the position of the stopper according to different wave requirements, so that the goods can stop accurately and flow smoothly on the straight section. At the same time, this strategy also takes into account the optimization of the order of goods out of the box and in the box, which helps to improve the operating efficiency of the entire conveyor line.

[0125] Specifically, the electrical system of the high-speed stopper equipment for the high-speed roller conveyor line of the present invention, the control strategy of the stopper and the box-out section of the transfer machine, includes:

[0126] After the control of the transfer section out-box stopper starts, it is initialized first, and the stopper drops to the lower limit position. The turnover box at the previous station is out, and the transfer section of this station accumulates and moves straight to move the box in. The host computer command is retrieved to determine whether the turnover box is transported to the transfer and out-box straight section for accumulation. If not, it is determined whether the accumulation section of the next station is allowed to enter the box. Under the condition that the box is allowed to enter, the turnover box of this station is out to the next station. If the turnover box needs to be transported to the transfer and out-box straight section for accumulation, the stopper rises to the upper limit position. After the turnover box of this station is in place, it touches the stopper calibration position. It is determined whether the accumulation section of the transfer and out-box is allowed to enter. If the box is allowed to enter, the transfer and out-box is moved to the transfer and out-box straight section. Then the stopper drops to the lower limit position, and the stopper and the transfer section out-box control are completed.

[0127] In high-speed roller conveyor lines, when the stopper is used in conjunction with the transfer machine, especially in the box-out section, a set of sophisticated control strategies is required to ensure that the turnover boxes can be accurately and efficiently transported to the designated location. The following are the specific steps of the control strategy for the box-out section when the stopper is used in conjunction with the transfer machine:

[0128] Initialization: After the control strategy starts, the initialization operation is performed first. The stopper will be lowered to the lower limit position, making it in the initial state and ready to start working.

[0129] The turnover boxes at the previous station are unpacked: Immediately afterwards, the turnover boxes at the previous station begin to be unpacked, preparing for the next stage of transportation.

[0130] The transfer section accumulation area of ​​this station starts the straight-forward box feeding operation at the same time as the turnover boxes are unloaded from the previous station, that is, receiving the turnover boxes from the previous station or preparing to receive new turnover boxes.

[0131] Retrieve the host computer instructions and determine the destination of the turnover box: The system will retrieve the instructions sent by the host computer to determine the destination of the current turnover box. If the turnover box does not need to be transported to the transfer and outbound straight line section for accumulation, the next step of judgment will be executed.

[0132] Determine whether the next station accumulation section allows the entry of boxes: If the turnover box is not transported to the transfer and unloading straight section, the system will check whether the next station accumulation section allows the entry of boxes. If allowed, the turnover box of this station will be directly unloaded to the next station.

[0133] The stopper rises to the upper limit position to prepare for receiving the box: If the turnover box needs to be transported to the straight section for transfer and outloading, the stopper will rise to the upper limit position to prepare for the accurate parking of the turnover box.

[0134] The turnover box is in place and calibrated: After the turnover box of this station is in place, it will hit the calibration position of the stopper, so that the turnover box can be parked accurately in the predetermined position.

[0135] Determine whether the transfer and outbound storage section allows the entry of containers: The system checks again whether the transfer and outbound storage section allows the entry of containers to confirm the safety of the next operation.

[0136] This station transfers out boxes to the straight line section of transfer out boxes: If the transfer out box section allows box entry, this station will use the transfer machine to transport the turnover box to the accumulation area of ​​the straight line section of transfer out boxes.

[0137] The stopper drops to the lower limit and ends the control: After the turnover box is successfully transported to the straight section for transferring and unloading, the stopper will drop to the lower limit, completing the control process of this unloading operation.

[0138] Through this control strategy, the stopper and the transfer machine can work closely together to ensure efficient and accurate transportation of the turnover box in the outbound section. At the same time, this strategy also takes into account the overall operating efficiency and safety of the conveyor line, avoiding production delays or accidents caused by inaccurate parking of turnover boxes or poor transportation.

[0139] Specifically, the electrical system of the high-speed stopper equipment for the high-speed roller conveyor line of the present invention, the control strategy of the stopper and the transfer machine box feeding section, includes:

[0140] After the control of the box feeding section of the transfer machine starts, the stopper is initialized first, the left stopper is lowered to the lower limit position, and the right stopper is lowered to the upper limit position;

[0141] Determine the direction of the transfer machine feeding the box. If it is a straight-line feeding, after the turnover box of this station is in place, determine whether the next station accumulation section allows the box to enter. If the box is allowed to enter, the turnover box of this station will be unloaded to the next station for accumulation;

[0142] If it is a left box transfer, the left stopper will drop to the lower limit position. After the right stopper rises to the upper limit position, it is determined whether the left stopper has dropped to the lower limit position. After the left stopper has dropped into place, the turnover box is transported from the left box transfer straight section to this station for accumulation. After it hits the baffle of the right stopper, the position is calibrated. After the turnover box of this station is in place, the left and right stoppers will both drop to the lower limit position. After both drop to the lower limit position, it is determined whether the accumulation section of the next station allows the box to enter. If the box is allowed to enter, the turnover box of this station will be transported to the next station for accumulation.

[0143] If it is a right box transfer, the right stopper will drop to the lower limit, and after the left stopper rises to the upper limit, it is determined whether the right stopper has dropped to the lower limit. After the right stopper has dropped into place, the turnover box is transported from the right box transfer straight section to this station for accumulation. The turnover box hits the left stopper baffle and calibrates the position. After the turnover box at this station is in place, the left and right stops will both drop to the lower limit. After both drop to the lower limit, it is determined whether the next station accumulation section allows the box to enter. If the turnover box is allowed to enter, the turnover box at this station will be transported to the next station for accumulation, and the stopper and the transfer machine section box entry control are completed.

[0144] In a high-speed roller conveyor line, when the stopper is used in conjunction with a transfer machine for the box-infeeding section, a set of sophisticated control strategies is required to enable the turnover box to enter the specified position accurately and efficiently. The following are the specific steps of the control strategy for the stopper combined with the transfer machine for the box-infeeding section:

[0145] Initialization: After the control strategy starts, the initialization operation is performed first. The left stopper and the right stopper will drop to the lower limit position, which is their initial state and ready to start working.

[0146] Determine the direction of the transfer machine's box feeding: Next, the system will determine the direction of the transfer machine's box feeding. This direction determines how the turnover box will be transported to the accumulation area of ​​this station.

[0147] Straight forward box handling: If the transfer machine is straight forward, that is, the turnover box is directly transported to this station along a straight line, then when the turnover box is in place, the system will determine whether the next station accumulation section allows the box to enter. If allowed, the turnover box of this station will be unloaded to the next station accumulation area.

[0148] Left-side box transfer processing: If the transfer machine is left-side box feed, that is, the turnover box is transported to this station from the left side, then the control strategy will first let the left stopper drop to the lower limit, and at the same time the right stopper rise to the upper limit. Then, the system will determine whether the left stopper has dropped into place. Once the left stopper is in place, the turnover box will be transported from the left-side box transfer straight section to the accumulation area of ​​this station. When the turnover box hits the right stopper baffle, the system will calibrate its position so that the turnover box is parked accurately. After that, both the left stopper and the right stopper will drop to the lower limit. Finally, the system will again determine whether the accumulation section of the next station allows the box to enter. If allowed, the turnover box of this station will be shipped to the next station.

[0149] Right-side box transfer processing: If the transfer machine is right-side box, that is, the turnover box is transported to this station from the right, the processing flow is similar to the left-side box, but the action of the stopper is opposite. The right stopper will first drop to the lower limit, and the left stopper will rise to the upper limit. Then, the system will determine whether the right stopper has dropped in place, and control the conveying and calibration position of the turnover box accordingly. Finally, both stoppers will drop to the lower limit and determine the box entry conditions of the next station.

[0150] End control: No matter from which direction the turnover box enters this station, once it is successfully unpacked to the accumulation area of ​​the next station, the control strategy of the stopper and the transfer machine section entering the box will end and wait for the next box entry operation.

[0151] Through this set of control strategies, the stopper and the transfer machine can work closely together to ensure efficient and accurate transportation of the turnover boxes in the box entry section. This strategy not only improves the overall operating efficiency of the conveyor line, but also enhances the flexibility and adaptability of the system, and can cope with the box entry needs in different directions and conditions.

[0152] Specifically, the electrical system of the high-speed stopper equipment for the high-speed roller conveyor line of the present invention, the control strategy of the stopper and the box-out section of the pendulum machine, includes:

[0153] After the stopper is matched with the pendulum machine for box discharge control, it is initialized first, the pendulum machine turns to the straight direction, the stopper drops to the lower limit, the turnover box at the previous station is discharged, and the transfer section of this station accumulates and enters the box in a straight line. The host computer command is retrieved to determine whether the turnover box is transported to the pendulum machine out of the straight line section for accumulation. If not, it is determined whether the accumulation section of the next station is allowed to enter the box. Under the condition that the box is allowed to enter, after the pendulum machine turns to the straight-line discharge direction, the turnover box of this station is discharged to the next station. If the turnover box needs to be transported to the pendulum machine out of the straight line section for accumulation, the stopper rises to the upper limit. After the turnover box of this station is in place, it touches the stopper calibration position, and the pendulum machine turns to the balance wheel branch out of the box direction to determine whether the balance wheel branch out of the box section accumulation allows the box to enter. If the box is allowed, the pendulum machine of this station discharges the box to the balance wheel machine branch out of the straight line section, and then the stopper drops to the lower limit, and the stopper combined with the pendulum machine section out of the box control ends.

[0154] In high-speed roller conveyor lines, when the stopper is used in conjunction with the pendulum machine for the box-out section, a sophisticated control strategy is required to ensure that the turnover boxes can be accurately and efficiently transported to the specified location. The following are the specific steps of the control strategy for the box-out section when the stopper is combined with the pendulum machine:

[0155] Initialization: After the control strategy starts, the initialization operation is performed first. The pendulum machine turns to the straight direction to prepare for the transportation of the turnover box. At the same time, the stopper drops to the lower limit, which is also its initial state.

[0156] The turnover boxes from the previous station are unloaded and transported to this station along the conveyor line. The turnover boxes in the transfer section and storage area of ​​this station will be transported in a straight line, that is, the turnover boxes will directly enter the storage area of ​​this station along a straight line.

[0157] Determine the destination of the turnover box: The system will retrieve the host computer instructions to determine whether the turnover box needs to be transported to the straight line section of the pendulum machine for accumulation. This judgment is based on the current transportation task and destination requirements.

[0158] If it does not need to be transported to the straight section of the pendulum machine for box discharge: If the turnover box does not need to be transported to the straight section of the pendulum machine for box discharge, the system will continue to determine whether the next station accumulation section allows box entry. If allowed, the pendulum machine will turn to the straight-line box discharge direction, and then the turnover box of this station will be discharged to the accumulation area of ​​the next station.

[0159] If the box needs to be transported to the straight section of the box out of the oscillating wheel machine: If the box needs to be transported to the straight section of the box out of the oscillating wheel machine, the stopper will rise to the upper limit to prepare for the accurate parking of the box. When the box at this station is in place, it will hit the calibration position of the stopper, so that the box can be parked accurately at the specified position.

[0160] The wheel turning direction and the judgment of the branching out of the box: After the turnover box is parked in place, the wheel will turn to the direction of the wheel branching out of the box, ready to convey the turnover box to the straight section of the wheel branching out of the box. At this time, the system will again judge whether the accumulation of the wheel branching out of the box section allows the box to enter, so as to ensure the smooth operation of the conveyor line.

[0161] The balance machine unpacks and the stopper resets: If the balance wheel branch unpacking section allows the box to enter, the balance machine will unpack the turnover box to the balance wheel branch unpacking straight line section. After the unpacking is completed, the stopper will drop to the lower limit, return to the initial state, and wait for the next control command.

[0162] Control ends: So far, the control strategy of the stopper and the pendulum machine box-out section ends. Throughout the whole process, the system uses precise control and judgment to ensure the accurate and efficient transportation of the turnover box on the high-speed roller conveyor line.

[0163] This control strategy fully considers the coordinated work of the pendulum machine and the stopper, as well as the needs of different accumulation sections on the conveyor line. Through real-time monitoring and flexible adjustment, the system can cope with complex conveying tasks and improve the overall operating efficiency and stability of the conveyor line.

[0164] In a second aspect, the present invention provides a control method for a high-speed roller conveyor line high-speed stopper device, which is applied to the electrical system of the high-speed roller conveyor line high-speed stopper device, comprising:

[0165] Step S101, obtaining the stopper device information and the stopper installation position information;

[0166] Step S102, matching the stopper installation position information in a preset control strategy knowledge base to obtain a control strategy corresponding to the stopper installation position, the control strategy knowledge base includes a control strategy for a stopper with a straight line segment, a control strategy for a stopper with a transfer machine out-of-box segment, a control strategy for a stopper with a transfer machine in-box segment, and a control strategy for a stopper with a pendulum machine out-of-box segment;

[0167] Step S103, initializing the stopper so that the stopper descends to the lower limit position, and converting the control strategy corresponding to the installation position of the stopper into control information;

[0168] Step S104, sending control information to the DC brushless motor driver of the stopper, the control information including a start signal and a direction signal, the start signal and the direction signal control the DC brushless motor driver of the stopper, and are used to make the DC brushless motor rotate forward and reverse, thereby driving the stopper baffle to move up and down.

[0169] Specifically, the high-speed stopper device control method for a high-speed roller conveyor line according to the present invention, the step S102 includes:

[0170] The control strategy of the stopper combined with the straight line segment includes initialization after the stopper control starts, the stopper drops to the lower limit, and the wave of the upper computer controlling the straight line segment is determined. If it is a wave collection control, it is determined whether the station is unloading. If not, the stopper rises to the upper limit. If the station is unloading, the turnover box leaves the station for accumulation and arrives at the next station for accumulation. The stopper rises to the upper limit, and then after the station completes the box loading and touches the stopper calibration position, the stopper is detected to be in the raised state, then the station stops unloading, and the wave collection is completed. If it is a release wave, the upper computer controls the stopper to release the wave. After the stopper drops to the lower limit, the station accumulation detects that the stopper has completed its descent, then the station turnover box is unloaded, the release wave control is completed, and the stopper combined with the straight line segment control ends.

[0171] Specifically, the high-speed stopper device control method for a high-speed roller conveyor line according to the present invention, the step S102 includes:

[0172] The control strategy of the stopper combined with the transfer machine outbound section includes initialization after the control of the stopper of the transfer section outbound section starts, the stopper drops to the lower limit position, the turnover box is discharged from the previous station, the transfer section of this station accumulates and moves straight into the box, retrieves the host computer instruction, and determines whether the turnover box is transported to the transfer and outbound straight section for accumulation. If not, it determines whether the accumulation section of the next station allows the box to enter. Under the condition that the box is allowed to enter, the turnover box of this station is discharged to the next station. If the turnover box needs to be transported to the transfer and outbound straight section for accumulation, the stopper rises to the upper limit position, and the turnover box of this station touches the stopper calibration position after it is in place. It is determined whether the transfer and outbound section accumulation allows the box to enter. If the box is allowed, the transfer and outbound box of this station is transferred to the transfer and outbound straight section, and then the stopper drops to the lower limit position, and the outbound control of the stopper combined with the transfer machine section ends.

[0173] Specifically, the high-speed stopper device control method for a high-speed roller conveyor line according to the present invention, the step S102 includes:

[0174] The control strategy of the stopper and transfer machine box feeding section includes: after the control of the stopper and transfer machine box feeding section starts, it is initialized first, the left stopper is lowered to the lower limit position, and the right stopper is lowered to the upper limit position;

[0175] Determine the direction of the transfer machine feeding the box. If it is a straight-line feeding, after the turnover box of this station is in place, determine whether the next station accumulation section allows the box to enter. If the box is allowed to enter, the turnover box of this station will be unloaded to the next station for accumulation;

[0176] If it is a left box transfer, the left stopper will drop to the lower limit position. After the right stopper rises to the upper limit position, it is determined whether the left stopper has dropped to the lower limit position. After the left stopper has dropped into place, the turnover box is transported from the left box transfer straight section to this station for accumulation. After it hits the baffle of the right stopper, the position is calibrated. After the turnover box of this station is in place, the left and right stoppers will both drop to the lower limit position. After both drop to the lower limit position, it is determined whether the accumulation section of the next station allows the box to enter. If the box is allowed to enter, the turnover box of this station will be transported to the next station for accumulation.

[0177] If it is a right box transfer, the right stopper will drop to the lower limit, and after the left stopper rises to the upper limit, it is determined whether the right stopper has dropped to the lower limit. After the right stopper has dropped into place, the turnover box is transported from the right box transfer straight section to this station for accumulation. The turnover box hits the left stopper baffle and calibrates the position. After the turnover box at this station is in place, the left and right stops will both drop to the lower limit. After both drop to the lower limit, it is determined whether the next station accumulation section allows the box to enter. If the turnover box is allowed to enter, the turnover box at this station will be transported to the next station for accumulation, and the stopper and the transfer machine section box entry control are completed.

[0178] Specifically, the high-speed stopper device control method for a high-speed roller conveyor line according to the present invention, the step S102 includes:

[0179] The control strategy of the stopper and the pendulum machine out-box section includes: the stopper and the pendulum machine out-box control are initialized first after starting, the pendulum machine turns to the straight direction, the stopper drops to the lower limit, the turnover box of the previous station is out, the transfer section of this station accumulates and enters the box straightly, retrieves the host computer instruction, and determines whether the turnover box is transported to the pendulum machine out-box straight section for accumulation. If not, it determines whether the accumulation section of the next station allows the box to enter. Under the condition that the box is allowed to enter, the pendulum machine turns to the straight out-box direction. After that, the turnover box of this station is unloaded to the next station. If the turnover box needs to be transported to the straight section of the pendulum machine for accumulation, the stopper rises to the upper limit position. After the turnover box of this station is in place, it touches the calibration position of the stopper, and the pendulum machine turns to the direction of the balance wheel branch outbound box to determine whether the balance wheel branch outbound box section accumulation allows the box to enter. If the box is allowed to enter, the pendulum machine of this station will unload the box to the straight section of the pendulum machine branch outbound box, and then the stopper will drop to the lower limit position, and the stopper and the pendulum machine section outbound box control will end.

[0180] like Figure 2As shown, the stopper is installed between the last electric roller for accumulating the straight section of this station and the first electric roller for accumulating the straight section of the next station.

[0181] like Figure 3 As shown, after the control of the straight line segment stopper starts, it is initialized first, and the stopper drops to the lower limit. Determine the wave of the upper computer controlling the straight line segment. If it is a wave collection control, determine whether the station is unloading. If not, the stopper rises to the upper limit. If the station is unloading, the turnover box leaves the station accumulation and arrives at the next station accumulation, and the stopper rises to the upper limit. Then, after the station completes the box loading and touches the stopper calibration position, the stopper is detected to be in the raised state, then the station stops unloading, and the wave collection is completed. If it is a release wave, the upper computer controls the stopper to release the wave. After the stopper drops to the lower limit, the station accumulation detects that the stopper has dropped, then the turnover box of the station is unloaded, and the release wave control is completed. The stopper is matched with the straight line segment control to end.

[0182] like Figure 4 As shown, the stopper is installed between the last electric roller for accumulation in the transfer section of this station and the first electric roller for accumulation in the straight section of the next station.

[0183] like Figure 5 As shown, after the control of the transfer section out-box stopper starts, it is initialized first, and the stopper drops to the lower limit. The turnover box is discharged from the previous station, and the transfer section of this station accumulates and moves straight to bring in the box. Retrieve the host computer instruction to determine whether the turnover box is transported to the transfer and out-box straight section for accumulation. If not, determine whether the accumulation section of the next station allows the entry of the box. Under the condition that the entry of the box is allowed, the turnover box of this station is discharged to the next station. If the turnover box needs to be transported to the transfer and out-box straight section for accumulation, the stopper rises to the upper limit, and the turnover box of this station hits the stopper calibration position after it is in place. Determine whether the accumulation section of the transfer and out-box is allowed to enter the box. If the entry of the box is allowed, the transfer and out-box of this station is transferred to the transfer and out-box straight section, and then the stopper drops to the lower limit, and the stopper and the transfer section out-box control ends.

[0184] like Figure 6 As shown, the left box feeding of the transfer machine: the stopper is installed between the right side of the accumulation line of the transfer machine section of this station and the first accumulation roller of the straight line section of the right box feeding of the transfer machine. The right box feeding of the transfer machine: the stopper is installed between the left side of the accumulation line of the transfer machine section of this station and the first accumulation roller of the straight line section of the left box feeding of the transfer machine.

[0185] like Figure 7 As shown, the stopper is initialized after the control of the box feeding section of the transfer machine starts, the left stopper drops to the lower limit position, and the right stopper drops to the upper limit position.

[0186] Determine the direction of the box loading of the transfer machine. If it is a straight-line box loading, then after the turnover box of this station is in place, determine whether the next station's accumulation section allows the box to enter. If the box is allowed to enter, the turnover box of this station will be unloaded and transferred to the next station for accumulation.

[0187] If it is a left-side box transfer, the left stopper will drop to the lower limit position. After the right stopper rises to the upper limit position, it is determined whether the left stopper has dropped to the lower limit position. After the left stopper has dropped into place, the turnover box is transported from the left-side box transfer straight section to this station for accumulation. After it hits the right stopper baffle, it is calibrated to the position. After the turnover box of this station is in place, the left and right stops will both drop to the lower limit position. After both drop to the lower limit position, it is determined whether the accumulation section of the next station allows the box to enter. If the box is allowed to enter, the turnover box of this station will be transported to the next station for accumulation.

[0188] If it is a right box transfer, the right stopper will drop to the lower limit position, and after the left stopper rises to the upper limit position, it is determined whether the right stopper has dropped to the lower limit position. After the right stopper drops to the right limit position, the turnover box is transported from the right box transfer straight section to the station for accumulation. After hitting the left stopper baffle, the position is calibrated. After the turnover box of this station is in place, the left and right stoppers will drop to the lower limit position. After both drop to the lower limit position, it is determined whether the next station accumulation section allows the box to enter. If the box is allowed to enter, the turnover box of this station will be transported to the next station for accumulation. The stopper is matched with the transfer section for control.

[0189] like Figure 8 As shown, the stopper is installed between the last electric roller for accumulation in the transfer section of this station and the first electric roller for accumulation in the straight section of the next station.

[0190] like Fig. 9 As shown, the stopper is initialized after the control of the box discharge of the swing wheel machine starts, the swing wheel machine turns to the straight direction, and the stopper drops to the lower limit. The turnover box of the previous station is discharged, and the transfer section of this station accumulates and enters the box in a straight line. The host computer command is retrieved to determine whether the turnover box is transported to the straight line section of the swing wheel machine for accumulation. If not, it is determined whether the accumulation section of the next station allows the box to enter. Under the condition that the box is allowed to enter, the swing wheel machine turns to the straight direction of the box discharge, and the turnover box of this station is discharged to the next station. If the turnover box needs to be transported to the straight line section of the swing wheel machine for accumulation, the stopper rises to the upper limit, and the turnover box of this station hits the stopper calibration position after it is in place, and the swing wheel machine turns to the swing wheel branch box discharge direction. It is determined whether the accumulation of the swing wheel branch box discharge section allows the box to enter. If the box is allowed to enter, the swing wheel machine of this station discharges the box to the straight line section of the swing wheel machine branch box discharge, and then the stopper drops to the lower limit, and the control of the box discharge of the stopper and the swing wheel machine section ends.

[0191] The technical solution of the present invention solves the problem of slow beat and instability of the stopper when used on a high-speed conveyor line by the following methods:

[0192] Replace the power source: Traditional stops usually use cylinders as the power source, and their lifting speed and action rhythm are highly dependent on the stability of the air source pressure. On high-speed conveyor lines, this dependence will cause the stopper's action rhythm to be slow and unstable. The present invention uses a brushless DC motor as the power source of the stopper. This motor has a faster response speed and higher stability, and can meet the high-speed conveyor line's requirements for fast and accurate stopper action.

[0193] Design of electrical system and control method: The present invention provides a special electrical system, including components such as controller, ASI gateway, ASI electric roller drive module, proximity switch, DC brushless motor driver, etc., which work together to achieve precise control of the stopper. The controller integrates a data acquisition unit, a control measurement matching unit, a control command conversion unit and a control command execution unit, which can generate corresponding control information according to the installation position of the stopper and the preset control strategy, and control the action of the stopper through the DC brushless motor driver.

[0194] Preset control strategy knowledge base: The present invention presets a control strategy knowledge base in the controller, including the control strategy of the stopper with the straight line section, the control strategy of the stopper with the transfer machine out-box section, the control strategy of the stopper with the transfer machine in-box section, and the control strategy of the stopper with the swing wheel machine out-box section. These control strategies are optimized for different conveyor line scenarios, and can improve the action rhythm and stability while ensuring the accuracy of the stopper action.

[0195] Real-time monitoring and feedback: The present invention monitors the position of the stopper in real time through the upper limit proximity switch and the lower limit proximity switch, so that the stopper is always in the correct position during the action. At the same time, the DC brushless motor driver feeds back the fault signal to the ASI electric roller drive module, and the controller can adjust the control strategy in time according to the feedback information to ensure the stable operation of the stopper.

[0196] In summary, the present invention effectively solves the problem of slow and unstable application of the stopper on the high-speed conveyor line by replacing the power source, designing a special electrical system and control method, presetting the control strategy knowledge base, and real-time monitoring and feedback.

[0197] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. If these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these changes and variations.
