[0052] The control method of the bulk-to-container loading and unloading process system of a port is characterized by comprising the following steps:

[0053] Step Ⅰ: Unloading;

[0054] A truck loaded with bulk coke and coal is driven into the unloading system, and the unloading platform turns the truck over to unload the bulk cargo into the underground hopper. The truck then drives away, and the bulk cargo in the underground hopper is sent to the ground through the first conveying device and transferred to the stockpiling system.

[0055] Step II: Stacking;

[0056] The stockpiling system operates to stack bulk cargo into stockpiles of predetermined sizes;

[0057] Step III: Packing;

[0058] The second transfer device delivers the bulk cargo from the stockpile to the packing system, and the packing system packs the bulk cargo into containers;

[0059] Step IV: Send the box;

[0060] The container delivery system delivers empty containers to the loading station and transports full containers away for storage.

[0061] A specific optimization scheme, step II adopts the following stockpile control method:

[0062] Step A, system information settings:

[0063] A1. Establish position coordinate system;

[0064] According to the position information in the stockpile yard, along the walking direction of the stocker, the walking starting point and the walking ending point are set, and the walking starting point is used as the coordinate origin to establish a coordinate system, and the stacks in the stockpile yard are numbered one by one, and the stacks on the left side of the stocker are numbered as l1, l2...ln, and the stacks on the right side of the stocker are numbered as r1, r2, r3...rn, and each stack is respectively provided with a corresponding shooting device, a height sensor, a pressure sensor and a wireless signal transmission module, and corresponding to the stack number, the shooting device number is lp1, lp2...lpn, rp1, rp2...rpn, the height sensor number is lh1, lh2...lhn, rh1, rh2...rhn, and the corresponding pressure sensor number is lg1, lg2...lgn, rg1, rg2...rgn, and after the stack number and the position information are matched one by one, the stack number and the position information are stored in the PLC;

[0065] A2. Correct the stockpiling parameters;

[0066] The data acquisition device acquires real-time image information, real-time height information and real-time gravity information of each stacking position in the stockpile yard, and updates and stores the acquired information in the PLC;

[0067] A3. Set the stacking information;

[0068] Pre-set a material coding mechanism in the PLC, encode the material information of the materials to be stacked, enter the material code into the PLC before stacking, and then calculate the upper limit value Hmax of the stacking height and the upper limit value Gmax of the stacking gravity corresponding to each stack position according to the information obtained in A1 and A2, and set them in the PLC;

[0069] Step B: Automatic stacking control:

[0070] B1. Stacking preparation;

[0071] The PLC sends an instruction, the traveling mechanism and the rotating mechanism are started, the stacker moves to the first stack position and then stops, the pitching mechanism is started, the stacker is adjusted to the stacking position, and then the data acquisition device is triggered and obtains real-time image information, real-time height information and real-time gravity information again, and then transmits the obtained information to the PLC;

[0072] B2. Stacking judgment;

[0073] The PLC receives the real-time information and makes a judgment. If the obtained height information 0 < H < Hmax or the gravity information 0 < G < Gmax, it is necessary to further judge whether stacking is required for this stack position and perform operation B3; if the obtained gravity information G = 0 and the height information H = 0, it is determined that stacking is required for this stack position and perform operation B4;

[0074] B3. Further stacking judgment;

[0075] When 0 < H < Hmax or 0 < G < Gmax, there are already materials at this stack position. Compare the material code information obtained in real time with the material code information to be stacked this time. If they are exactly the same, it is determined that stacking can be performed and operation B4 is executed; if they are not exactly the same, it is determined that stacking cannot be performed and operation B5 is executed;

[0076] B4. Stacking;

[0077] The PLC sends an instruction, the cantilever belt conveyor and the tail car belt conveyor are started, the stacker performs the stacking operation, the data acquisition device obtains real-time image information, real-time height information and real-time gravity information in real time and transmits them to the PLC. The PLC makes a real-time judgment. When either H = Hmax or G = Gmax is achieved, it is determined that the stacking is completed and the stacking is stopped, and then operation B5 is executed;

[0078] B5. Execute the next stacking preparation;

[0079] When stacking is completed or cannot be completed, the PLC sends a command, the walking mechanism and the rotating mechanism start, the stacker moves to the next stacking position and then stops, and repeats operations B1-B5. The movement sequence of the stacker is l1, r1, l2, r2...ln, rn, until stacking is completed on all stacking positions.

[0080] A specific optimization scheme, step III adopts the following packing control method:

[0081] Step 1: The information processing module is set to record the maximum height Hmax and the maximum mass Mmax of the container materials, and wait for the container to be turned over;

[0082] Step 2: Turn over the container and place it on the load-bearing module. The pressure sensor transmits the detected data to the information processing platform through the wireless signal transmission module. The information processing platform analyzes the acquired data and calculates the empty container mass M0. The control module sends a descending signal to the drive circuit relay to control the telescopic chute to descend until the dust cover at the lower end of the telescopic chute is buckled at the opening of the container. The material level sensor signal is transmitted to the information processing module through the wireless signal transmission module. The data information platform analyzes and calculates the empty container height H0.

[0083] Step 3: After data collection is completed, the control module transmits signals to the rail car and the unloading gate respectively, controls the unloading gate to open, and enables the rail car to drive the material distribution belt conveyor to move to the travel switch position. At this time, the two end hoppers of the material distribution belt conveyor are located directly above a group of buffer bins. The rail car touches the travel switch, and the travel switch transmits the signal to the control module. The control module sends a signal to the loading belt conveyor and the material distribution belt conveyor, so that they transport the materials into the container. The material level sensor and pressure sensor monitor the height and quality of the container materials in real time.

[0084] Step 4: When either Hmax or Mmax reaches the maximum value, the control module sends a stop unloading signal to the drive circuit relay to control the unloading gate to close. The control module sends a lifting signal to the drive circuit relay to control the telescopic slide and the dust cover to lift to the initial position to complete the container loading operation.

[0085] Step 5: The control module transmits a signal to the material distribution belt conveyor to make it rotate in the opposite direction to load the container at the other end. When any of the Hmax and Mmax values ​​of the other container reaches the maximum value, the control module sends a stop unloading signal to the drive circuit relay to control the unloading gate to close. The control module sends a lifting signal to the drive circuit relay to control the telescopic chute and the dust cover to lift to the initial position, completing the container loading operation and thus completing a set of container loading operations.

[0086] Step six: The control module transmits a signal to the rail car, causing the rail car to drive the material distribution belt conveyor to move above the other two containers. At this time, the rail car touches the travel switch, and the travel switch transmits a signal to the control module. The control module sends a signal to the loading belt conveyor and the material distribution belt conveyor, causing them to repeat steps four and five to complete the loading operation for another group of containers.

[0087] Due to the adoption of the above technical solution, compared with the prior art, the advantages of the present invention are:

[0088] 1. Optimized the process of each process link, improved the degree of automation, and saved manpower and material resources;

[0089] Second, adding dust removal and suppression measures in each link is beneficial to protecting the environment and meeting environmental protection requirements;

[0157] In this embodiment, the rotation axes 3711 of the adjacent upper and lower conical cylinders 3703 are vertically distributed, so that the rotation directions of the two conical cylinders 3703 can be vertical, avoiding all the conical cylinders 3703 from deflecting in one direction and interfering with each other.

[0158] The dust cover 3709 is provided with a through hole at the center, and the lower end of the discharge pipe 3708 is provided with a flange, the outer diameter of the flange is larger than the diameter of the through hole of the dust cover 3709, the lower end of the discharge pipe 3708 passes through the through hole of the dust cover 3709 and the flange is pressed against the lower end of the dust cover 3709, and a material level sensor is installed at the lower end of the dust cover 3709, and the material level sensor is connected to the reduction motor 3706 through a circuit, and the height of the telescopic chute 37 is automatically raised and lowered according to the loading material level.

[0162] The packing system has the following outstanding beneficial effects: 1. The present invention loads materials into the container through the feeding belt conveyor and the dividing belt conveyor. During the whole loading process, it is only necessary to drive the dividing belt conveyor to move to the upper end of the container through the rail car to load the materials. The hoppers at both ends of the dividing belt conveyor are respectively located directly above the two buffer bins. When the dividing belt conveyor fills the container at one end, the dividing belt conveyor is turned over to load the container at the other end, so that the dividing belt conveyor can move once to complete the loading operation of two containers, which greatly improves the loading efficiency; 2. There are four buffer bins placed under the material distribution belt conveyor. The four buffer bins are divided into two groups. Each pair of non-adjacent buffer bins forms a group. The hoppers at both ends of the material distribution belt conveyor are located directly above one of the buffer bins. When the present invention completes loading of the container under one of the buffer bins, it only needs to move a distance between two adjacent containers to move to the top of another buffer bin to continue loading the container. At this time, the group of containers that have completed loading is replaced. In this way, the above operation method can load the container uninterruptedly, greatly improving the loading efficiency. Advantages of telescopic chute: 1. The conical barrel of the present invention is hinged with the connecting ring. When the material impacts the inner wall of the conical barrel, the conical barrel can swing, thereby producing a certain buffering effect on the material; 2. The rotation axes of the adjacent upper and lower conical barrels of the present invention are vertically distributed, so that the rotation directions of the two conical barrels can be vertical, avoiding all the conical barrels from deflecting in one direction and interfering with each other.

When the equipment exceeds the set pressure value, the pressure switch will send a signal to the electric control box, and the electric control box will send a signal after receiving it, so that the main motor control power supply is separated and turned off. At this time, the oil pump motor in the hydraulic station stops running, which can prevent high pressure from damaging hydraulic components and pipelines, thereby protecting the equipment and extending the service life of the equipment;

[0174] The emergency stop device adopts a tripping disconnect switch, and an emergency stop button is configured on the electric control box. In an emergency, press the emergency stop button, which sends a signal to the controller.

[0176] In a specific embodiment, the container is first transported to the top of the load-bearing plate 422 by means of a transporting device, with the container door close to the direction of the standing platform 43. Then, the container lock 46 is manually operated to fix the container above the load-bearing plate 422. After that, the hydraulic station is manually started at the operating station.

If the acquired height information 0 < H < Hmax or the gravity information 0 < G < Gmax, it is necessary to further judge whether stacking is required for this stack position and perform operation B3; if the acquired gravity information G = 0 and the height information H = 0, it is determined that stacking is required for this stack position and perform operation B4;

[0199] B3. Further stacking judgment;

[0200] When 0 < H < Hmax or 0 < G < Gmax, there are already materials at this stack position. Compare the real-time acquired material code information with the material code information to be stacked this time. If they are exactly the same, it is determined that stacking can be carried out and perform operation B4; if they are not exactly the same, it is determined that stacking cannot be carried out and perform operation B5;

[0201] B4. Stacking;

[0202] The PLC sends a command, the cantilever belt conveyor and the tail car belt conveyor start, the stacker performs the stacking operation, and the data acquisition device obtains real-time image information, real-time height information and real-time gravity information in real time, and transmits them to the PLC. The PLC makes a real-time judgment. When either H=Hmax or G=Gmax is achieved, it determines that the stacking is completed and stops stacking, and then executes the B5 operation;

[0203] B5. Carry out the next stockpile preparation;

[0204] When stacking is completed or cannot be completed, the PLC sends a command, the walking mechanism and the rotating mechanism start, so that the stacker moves to the next stacking position and then stops, and repeats B1-B5 operations until stacking is completed on all stacking positions.

[0205] In step A1, the stacking positions on the left side of the stacker are numbered as l1, l2, ..., ln, and the stacking positions on the right side of the stacker are numbered as r1, r2, r3, ..., rn.

[0206] Each stack is respectively provided with a photographing device, a height sensor, a pressure sensor and a wireless signal transmission module, and has corresponding stack number, the photographing device number is lp1, lp2...lpn, rp1, rp2...rpn, the height sensor number is lh1, lh2...lhn, rh1, rh2...rhn, and the corresponding pressure sensor number is lg1, lg2...lgn, rg1, rg2...rgn, the photographing equipment, height sensor and pressure sensor are connected to the wireless signal transmission module through a signal transmission line, and the wireless signal transmission module is connected to the PLC wirelessly.

[0207] In the repeated operation of step B5, the moving order of the stacker is l1, r1, l2, r2...ln, rn.

[0208] In step A2, the real-time height H1 of the pile is calculated based on the real-time image information, and the real-time height H2 of the pile is calculated based on the height information. The calculated heights H1 and H2 of the pile are compared. When the data are consistent, the equipment is judged to be in normal use. When the data are inconsistent, the actual height H is re-acquired and compared with the heights H1 and H2. The equipment with the correct value is selected for continued use, and the equipment with erroneous data is repaired in time.

[0209] In step B4, the PLC calculates the swing amplitude of the pitch mechanism according to the acquired real-time image information, real-time height information and real-time gravity information, and sends instructions to the pitch mechanism, and the pitch mechanism executes according to the instructions.

[0210] Step III adopts the following packing control method, including the following steps:

[0211] Step 1: The information processing module is set to record the maximum height Hmax and the maximum mass Mmax of the container materials, and wait for the container to be turned over;

[0212] Step 2: Turn over the container and place it on the load-bearing module. The pressure sensor transmits the detected data to the information processing platform through the wireless signal transmission module. The information processing platform analyzes the acquired data and calculates the empty container mass M0. The control module sends a descending signal to the drive circuit relay to control the telescopic chute to descend until the dust cover at the lower end of the telescopic chute is buckled at the opening of the container. The material level sensor signal is transmitted to the information processing module through the wireless signal transmission module. The data information platform analyzes and calculates the empty container height H0.

[0213] Step 3: After data collection is completed, the control module transmits signals to the rail car and the unloading gate respectively, controls the unloading gate to open, and enables the rail car to drive the material distribution belt conveyor to move to the travel switch position. At this time, the two end hoppers of the material distribution belt conveyor are located directly above a group of buffer bins. The rail car touches the travel switch, and the travel switch transmits the signal to the control module. The control module sends a signal to the loading belt conveyor and the material distribution belt conveyor, so that they transport the materials into the container. The material level sensor and pressure sensor monitor the height and quality of the container materials in real time.

[0214] Step 4: When either Hmax or Mmax reaches the maximum value, the control module sends a stop unloading signal to the drive circuit relay to control the unloading gate to close. The control module sends a lifting signal to the drive circuit relay to control the telescopic slide and the dust cover to lift to the initial position to complete the container loading operation.

[0215] Step 5: The control module transmits a signal to the material distribution belt conveyor to make it rotate in the opposite direction to load the container at the other end. When any of the Hmax and Mmax values ​​of the other container reaches the maximum value, the control module sends a stop unloading signal to the drive circuit relay to control the unloading gate to close. The control module sends a lifting signal to the drive circuit relay to control the telescopic chute and the dust cover to lift to the initial position, completing the container loading operation and thus completing a set of container loading operations.

[0216] Step six: The control module transmits a signal to the rail car, causing the rail car to drive the material distribution belt conveyor to move above the other two containers. At this time, the rail car touches the travel switch, and the travel switch transmits a signal to the control module. The control module sends a signal to the loading belt conveyor and the material distribution belt conveyor, causing them to repeat steps four and five to complete the loading operation for another group of containers.
