Description

Technical Field

[0001] The present invention belongs to the field of material transportation, and particularly relates to a control method for automatic scheduling of pharmaceutical glass raw material transportation. Background Art

[0002] In the feeding line for transporting pharmaceutical glass raw materials, after the raw materials are loaded at the raw material mixer, tools are used to transport the raw materials to the kiln furnace silo for feeding to ensure a sufficient and uninterrupted supply of raw materials in the kiln furnace silo. Currently, most systems in the industry use methods such as manual forklifts and overhead crane hoisting for transportation and feeding operations, resulting in low efficiency.

[0003] Therefore, it is necessary to design a control method for automatic scheduling of pharmaceutical glass raw material transportation to solve the above problems, greatly reducing manual intervention and improving work efficiency.

[0004] For example, the Chinese patent literature discloses an intelligent scheduling method for a material buffer circulation conveyor line [Patent Application No.: CN201610723663.5], which includes the following steps: S1: According to the allocation of production work orders, prepare materials and put them on the line; S2: Each material enters the corresponding work station in an orderly manner and starts working; S3: After the materials in the material frames of each work station are used up, the corresponding material frames are automatically recycled;

[0005] S4: Determine whether a work order shutdown command is received. If so, retreat the materials corresponding to the work order on the material buffer circulation conveyor line. Summary of the Invention

[0006] The purpose of the present invention is to provide a control method for automatic scheduling of pharmaceutical glass raw material transportation for the above problems.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0008] A control method for automatic scheduling of pharmaceutical glass raw material transportation includes several kiln furnace silos and raw material silos. The raw material silos are connected to a pit conveyor platform. Each kiln furnace silo corresponds to a hydraulic conveyor platform silo, and the hydraulic conveyor platform silo corresponds to two transition conveyor platforms, which are respectively used to transport empty cans and full cans. Each transition conveyor platform is connected to at least one buffer conveyor platform;

[0009] Step 1: The management system monitors the operating status of the current online lower-level machine control system, all conveyor platforms, and the status of the material cans on the conveyor platforms;

[0010] Step 2: The management system issues a scheduling task after making a judgment based on the status of the material cans on the conveyor platforms and the weight of the raw material silos, and issues a can-taking or can-releasing task to the RGV transfer vehicle;

[0011] Step 3: Each can has a tag for RFID identification. The RGV transfer vehicle receives the task of taking or placing cans and moves to the corresponding conveying platform through laser ranging and variable-frequency walking positioning. At the same time, the conveying platform receives the corresponding task of placing or taking cans.

[0012] In the above control method for automatic scheduling of pharmaceutical glass raw material transportation, the bin for the kiln is equipped with a weighing module. The weighing module can feedback the remaining materials in the bin for the kiln to the management system. When the management system receives that the remaining materials in the kiln bin are insufficient, the weighing module calculates the weight of the remaining materials and the weight of the raw materials to be supplemented. After receiving the information, the management system issues a discharging task and sequentially performs Step 1, Step 2, and Step 3, and then sequentially performs Step 4, Step 5, and Step 6;

[0013] Step 4: The raw materials in the raw material bin are placed on the pit conveying platform. The RGV transfer vehicle moves to the pit conveying platform and receives the can through the elevator.

[0014] Step 5: The RGV transfer vehicle places the can into the full-can conveyor, and the can is transferred to the full-can conveyor through the elevator and records are made and the information is fed back to the management system.

[0015] Step 6: The management system continues to issue a discharging task to the full-can conveyor. The RGV transfer vehicle moves to the corresponding buffer conveying platform and places the full can on the buffer conveying platform. The full can is transferred to the transition conveying platform for transporting the full can through the buffer conveying platform and finally transported to the hydraulic conveying platform bin and then transported into the bin for the kiln.

[0016] In the above control method for automatic scheduling of pharmaceutical glass raw material transportation, when the buffer conveying platform for placing empty cans is full of empty cans, the buffer conveying platform feeds back the information to the management system. After receiving the information, the management system issues a can-taking task and sequentially performs Step 1, Step 2, and Step 3, and then sequentially performs Step 7, Step 8, and Step 9;

[0017] Step 7: The RGV transfer vehicle moves to the corresponding buffer conveying platform for placing empty cans and takes out the empty can.

[0018] Step 8: The management system simultaneously sends a can-taking task to the empty-can conveyor. The RGV transfer vehicle 15 places the empty can into the empty-can conveyor.

[0019] Step 9: The RGV transfer vehicle moves to the pit conveying platform with the empty can and sends the empty can into the pit conveying platform through the elevator 19. The empty can waits for the next filling of raw materials.

[0020] In the above control method for automatic scheduling of pharmaceutical glass raw material transportation, when the quantity of materials in raw material bin 11 decreases and replenishment is required, the weighing module in the original granary sends feedback information to the management system. After receiving the information, the management system issues a raw material replenishment task and sequentially performs Step 1, Step 2, and Step 3, and then proceeds to the next step;

[0021] Step 10: The RGV transfer vehicle receives the information, moves to the external equipment to collect the raw material tank, moves to the pit conveyor platform, and sends the raw material tank into the pit conveyor platform through the elevator and pours it into the raw material bin.

[0022] In the above control method for automatic scheduling of pharmaceutical glass raw material transportation, the raw material bin is provided with a white material loading port and a color material loading port, and the tank material is sent into the corresponding loading port through RFID identification.

[0023] In the above control method for automatic scheduling of pharmaceutical glass raw material transportation, the two transition conveyor platforms corresponding to the hydraulic conveyor platform bin can automatically replace empty and full tanks. When the state of the upper tank on the transition conveyor platform becomes an empty tank, it exchanges the empty and full tanks with the full tank on the nearest buffer conveyor platform.

[0024] In the above control method for automatic scheduling of pharmaceutical glass raw material transportation, the empty tank conveyor and the full tank conveyor can transport multiple tanks simultaneously, and the empty tank conveyor and the full tank conveyor are connected to the RGV transfer vehicle.

[0025] In the above control method for automatic scheduling of pharmaceutical glass raw material transportation, when the management system triggers a task, according to the distance relationship and the number of empty tanks in the bins used by the kiln, it preferentially schedules the empty material tanks with a large number of empty tanks and a long transportation distance to the raw material bin for batching.

[0026] In the above control method for automatic scheduling of pharmaceutical glass raw material transportation, for the tank areas that are online monitored and shown to be offline, faulty, or in manual state, the management system will automatically ignore the tanks in this area and will not perform the empty and full tank exchange and empty tank batching tasks.

[0027] In the above control method for automatic scheduling of pharmaceutical glass raw material transportation, under the scheduling of the management system, Step 1, Step 2, and Step 3 can cooperate with each other to complete the required batching tasks without manual intervention.

[0028] Compared with the existing technology, the advantages of the present invention are as follows:

[0029] The through-tube management system issues a task of receiving / retrieving tanks to the RGV transfer vehicle, and automatically receives / retrieves tanks through the RGV transfer vehicle, replacing the transportation and feeding operations by manual forklifts and overhead crane hoisting, etc., to improve efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figure 1 is the logical flow block diagram of this method;

[0031] Figure 2 is the position schematic diagram. Specific Embodiment

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] This embodiment provides a control method for automatic scheduling of pharmaceutical glass raw material transportation, in combination with Figure 1-2 as shown;

[0034] It includes several kiln bins 10 and raw material bins 11. The raw material bin 11 is connected to a pit transportation platform 12. Each kiln bin 10 corresponds to a hydraulic transportation platform bin 13. The hydraulic transportation platform bin 13 corresponds to two transfer transportation platforms 14, and the two transfer transportation platforms 14 are respectively used for transporting empty cans and full cans. Each transfer transportation platform 14 is at least connected to one buffer transportation platform 16;

[0035] Step 1: The management system monitors the operating status of the current online lower-level machine control system, all transportation platforms, and the status of the material tanks on the transportation platforms;

[0036] Step 2: The management system judges according to the status of the material tanks on the transportation platforms and the weight of the raw material bin 11, then issues a scheduling task, and issues a task of taking or placing a can to the RGV transfer vehicle 15;

[0037] Step 3: Each can has a tag for RFID identification. The RGV transfer vehicle 15 receives the task of taking or placing a can, and moves to the corresponding transportation platform through laser ranging and variable-frequency walking positioning. At the same time, the transportation platform receives the corresponding task of placing or taking a can.

[0038] The kiln bin 10 is provided with a weighing module, and the weighing module can feedback the remaining materials in the kiln bin 10 to the management system. When the management system receives that the remaining materials in the kiln bin are insufficient, the weighing module calculates the weight of the remaining materials and the weight of the raw materials that need to be replenished. After the management system receives the information, it issues a discharging task, and then sequentially performs Step 1, Step 2, and Step 3, and then sequentially performs Step 4, Step 5, and Step 6;

[0039] Step 4: The raw materials in the raw material bin 11 are placed on the pit transportation platform 12. The RGV transfer vehicle 15 moves to the pit transportation platform 12 and receives the can through the elevator 19;

[0040] Step 5: The RGV transfer vehicle 15 places the can into the full-can conveyor 18, and transfers the can to the full-can conveyor 18 through the elevator 19, and records and feeds back the information to the management system;

[0041] Step 6: The management system continues to issue an unloading task to the full-tank conveyor 18. The RGV transfer vehicle 15 moves to the corresponding buffer conveyor platform 16 and places the full tank on the buffer conveyor platform 16. The full tank is transferred to the transition conveyor platform 14 for transporting the full tank through the buffer conveyor platform 16, and finally transported to the hydraulic conveyor platform silo 13 and then transported into the kiln furnace bin 10.

[0042] When the buffer conveyor platform 16 for placing empty tanks is full of empty tanks, the buffer conveyor platform 16 feeds back the information to the management system. After receiving the information, the management system issues a tank collection task and sequentially performs Step 1, Step 2, and Step 3, and then sequentially performs Step 7, Step 8, and Step 9;

[0043] Step 7: The RGV transfer vehicle 15 moves to the corresponding buffer conveyor platform 16 for placing empty tanks and takes out the empty tanks;

[0044] Step 8: The management system simultaneously issues a tank picking task to the empty-tank conveyor 17. The RGV transfer vehicle 15 places the empty tanks into the empty-tank conveyor 17;

[0045] Step 9: The RGV transfer vehicle 15 moves to the pit conveyor platform 12 with the empty tanks and sends the empty tanks into the pit conveyor platform 12 through the elevator 19. The empty tanks wait for the next filling of raw materials.

[0046] When the material quantity in the raw material bin 11 decreases and needs to be replenished, the weighing module in the original grain bin sends feedback information to the management system. After receiving the information, the management system issues a raw material replenishment task and sequentially performs Step 1, Step 2, and Step 3, and then performs Step 10;

[0047] Step 10: The RGV transfer vehicle 15 receives the information, moves to the external equipment to collect the raw material tank, moves to the pit conveyor platform 12, and sends the raw material tank into the pit conveyor platform 12 through the elevator 19 and pours it into the raw material bin 11.

[0048] The raw material bin 11 is provided with a white material loading port and a color material loading port, and the tank material is fed into the corresponding loading port through RFID identification.

[0049] The two transition conveyor platforms 14 corresponding to the hydraulic conveyor platform silo 13 can automatically replace empty and full tanks. When the tank state on the transition conveyor platform 14 becomes an empty tank, it exchanges the empty and full tanks with the full tank on the nearest buffer conveyor platform 16.

[0050] The described empty-tank conveyor 17 and full-tank conveyor 18 can transport multiple tanks simultaneously, and the empty-tank conveyor 17 and full-tank conveyor 18 are connected to the RGV transfer vehicle 15.

[0051] When the management system triggers a task, based on the distance relationship and the number of empty cans in bin 10 of the kiln, it preferentially schedules the empty material cans with a large number of empty cans and a long conveying distance to the raw material bin 11 for batching.

[0052] For the tank areas that are monitored online and shown to be offline, faulty, or in manual status, the management system will automatically ignore the tanks in this area and will not perform the exchange of empty and full tanks and the empty tank batching task.

[0053] Steps 1, 2, and 3 can cooperate with each other to complete the required batching tasks without manual intervention under the scheduling of the management system.

[0054] All detection, execution components in the system, as well as communication with peripheral devices, are centrally controlled by the PLC controller, and tasks are issued by the management system.

[0055] The controller receives the detection signal of the travel switch sensor to mark and determine whether there is a tank currently;

[0056] The controller receives the detection signal of the RFID sensor to identify the current tank ID and distinguish the type of tank;

[0057] The controller receives the detection signal of the remote distance sensor to judge the current position of the RGV transfer vehicle;

[0058] The controller receives the detection signal of the weighing sensor to judge the weight of the raw material in the bin;

[0059] Control the driving of the trolley walking motor through the industrial bus method to achieve the automatic start and stop of the trolley, the free setting of the walking speed, and the real-time speed feedback;

[0060] Control the driving of the conveying chain motor through the industrial bus method to achieve the automatic start and stop of the conveying chain, the free setting of the conveying speed, and the real-time speed feedback;

[0061] Monitor the real-time status of the tanks on each conveyor and the remaining material weight of each bin through the Ethernet communication method. Judge whether to feed based on the remaining material in the bin, and judge whether to load at the raw material mixer based on the comparison of the number of empty and full tanks on the conveyor;

[0062] When the tank needs to be transferred on the platform, the RGV transfer vehicle performs precise positioning and transportation.

[0063] The travel switch sensor is installed at the entrance and exit of the conveyor to realize the function of detecting the presence or absence of the tank;

[0064] The remote distance sensor is installed in the walking direction of the RGV transfer vehicle to realize the detection of the current position of the trolley;

[0065] The RFID sensors are installed on the sides of the RGV transfer vehicle, the conveying platform, and the pit conveying platform to detect the ID of the material tank and determine the type of the material tank.

[0066] The weighing sensors are installed at the four corners of the silo to detect the weight of the raw materials in the silo.

[0067] The frequency converter can be controlled and alarm monitored through the human-machine interaction touch screen installed on site.

[0068] The system determines whether a device can perform the material tank conveying work by collecting whether each device in the lower computer is in the manual, automatic, or fault state. It determines whether feeding and batching operations are required by collecting the states of the material tanks (empty / full) on each conveyor and the weight of the raw materials in the silo. To ensure an adequate supply of raw materials in the silo, full material tanks are always stored on the conveyor in front of the silo, and a buffer conveyor is configured beside it to store spare raw materials. When the material tank discharges materials into the silo, the empty material tank needs to be promptly exchanged with the buffer full material tank. Since there are multiple silos and the types of raw materials required for each silo are not the same, each material tank needs to be numbered and given an ID. The storage and conveying position of each material tank can only be on a certain conveyor. After the RFID identifies the ID of the material tank, the material tank needs to be conveyed to the vicinity of different silos for storage.

Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
