Description

Technical Field

[0001] The present invention relates to the technical field of port handling devices, in particular to a container bulk cargo packing device and its control method. Background Art

[0002] The containerized transportation of bulk cargo has advantages such as safety, convenience, and environmental protection. One of the advantages of containerized transportation of bulk cargo compared to traditional transportation methods is that container transportation has no environmental pressure. Since the container adopts a fully enclosed method, it will not cause dust pollution to the environment. On the other hand, generally, the loss in bulk transportation accounts for 3 - 5% of the total volume, while there is no problem of transportation loss in containers.

[0006] The above - mentioned rail vehicle includes a vehicle frame, rail wheels, and a driving device. The vehicle frame is installed with multiple groups of rail wheels, a driving device is installed on the vehicle frame, the driving device is connected to the rail wheels through a transmission mechanism, and a distributing belt conveyor is installed at the upper end of the vehicle frame.

[0007] A head hopper is installed at the discharge end of the above - mentioned feeding belt conveyor.

[0008] The above-mentioned head hopper includes a hopper shell and a material guiding plate. The lower half of the hopper shell is provided with an inclined wall. A material guiding plate is installed on the wall opposite to the inclined wall of the hopper shell. The upper end of the material guiding plate is hinged to the inner wall of the hopper shell, and a threaded sleeve is installed on the outer wall of the hopper shell; the threaded sleeve cooperates with a limit screw rod, and the limit screw rod passes through the threaded through hole of the threaded sleeve and abuts against the back of the material guiding plate.

[0009] The discharge port of the above-mentioned buffer bin is connected to the telescopic chute through a discharge gate.

[0010] Four buffer bins are installed on the above-mentioned main frame body and are linearly and evenly distributed. The end hoppers of the material distributing belt conveyor are respectively located directly above the two buffer bins.

[0011] The above-mentioned four buffer bins are divided into two groups. Two non-adjacent buffer bins are in one group, and the end hoppers of the material distributing belt conveyor are located directly above one of the groups of buffer bins.

[0012] Two travel switches are installed on the above-mentioned main frame body on the movement track of the rail vehicle, and a bumper is installed on the frame of the rail vehicle.

[0013] An electric control system of a container bulk cargo packing device, characterized in that: it includes a data acquisition device, an information processing module, a control module and a drive circuit relay; the data acquisition device includes a material level sensor, a load-bearing module and a wireless signal transmission module. A pressure sensor is provided on the load-bearing module. The load-bearing module is located at the lower end of the container. The material level sensor and the pressure sensor are connected to the wireless signal transmission module through signal transmission wires. The wireless signal transmission module is wirelessly connected to the information processing module. The information processing module is connected to the control module by wired or wireless means. The control module is connected to the drive circuit relay by wired or wireless means. The drive circuit relay is connected to the drive devices of the feeding mechanism and the material guiding mechanism.

[0014] A control method for an electric control system of a container bulk cargo packing device, characterized in that:

[0015] Step 1: The above-mentioned information processing module sets and records the maximum value H of the height of the container material max and the maximum value M of the material quality max , and waits for the container to complete flipping;

[0016] Step 2: Flip the container. Place the container 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 to calculate the empty container mass M0 of the container. The control module sends a descending signal to the driving circuit relay to control the telescopic chute to descend until the dust-proof cover at the lower end of the telescopic chute is buckled at the opening of the container. The signal of the level sensor is transmitted to the information processing module through the wireless signal transmission module. The data information platform analyzes and calculates to obtain the empty container height H0 of the container.

[0017] Step 3: After the data collection is completed, the control module transmits signals to the rail car and the discharge gate respectively to control the opening of the discharge gate, so that the rail car drives the distributing belt conveyor to move to the position of the travel switch. At this time, the hoppers at both ends of the distributing belt conveyor are respectively 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 signals to the feeding belt conveyor and the distributing belt conveyor to convey the materials into the container. The level sensor and the pressure sensor monitor the height and mass of the materials in the container in real time.

[0018] Step 4: When max and max either value reaches the maximum value, the control module sends a stop discharging signal to the driving circuit relay to control the closing of the discharge gate. The control module sends a lifting signal to the driving circuit relay to control the telescopic chute and the dust-proof cover to be lifted to the initial position, completing the container loading operation for this container.

[0019] Step 5: The control module transmits a signal to the distributing belt conveyor to make it rotate in the reverse direction to load materials into the other container. When max and max either value of the other container reaches the maximum value, the control module sends a stop discharging signal to the driving circuit relay to control the closing of the discharge gate. The control module sends a lifting signal to the driving circuit relay to control the telescopic chute and the dust-proof cover to be lifted to the initial position, completing the container loading operation for this container, thus completing the loading operation for a group of containers.

[0020] Step 6: The control module transmits a signal to the rail car to make the rail car drive the distributing belt conveyor to move above the other two containers. At this time, the rail car touches the travel switch, and the travel switch transmits the signal to the control module. The control module sends signals to the feeding belt conveyor and the distributing belt conveyor to repeat Step 4 and Step 5 to complete the loading operation for another group of containers.

[0021] Compared with the prior art, the present invention has the following prominent beneficial effects:

[0022] 1. The present invention loads materials into a container through a feeding belt conveyor and a distributing belt conveyor. During the entire loading process, it is only necessary to drive the distributing belt conveyor to move to the upper end of the container by a rail vehicle for loading. The end hoppers at both ends of the distributing belt conveyor are respectively located directly above two buffer bins. When the distributing belt conveyor fills one end of the container, the distributing belt conveyor is flipped to load the other end of the container, so that the distributing belt conveyor can move once to complete the loading operation of two containers, greatly improving the loading efficiency.

[0023] 2. Four buffer bins are placed below the distributing belt conveyor of the present invention. The four buffer bins are divided into two groups, and every two non-adjacent buffer bins form a group. The end hoppers at both ends of the distributing belt conveyor are located directly above one of the groups of buffer bins. After the present invention finishes loading the container below one of the groups of buffer bins, it only needs to move a distance between two adjacent containers to move above the other group of buffer bins and continue to load the container. At this time, replace the group of containers that have been loaded. In this way, the container can be continuously loaded, greatly improving the loading efficiency.

[0030] The present invention will be further described below in conjunction with the drawings of the specification and the specific embodiments.

[0031] As Figure 1 and 2 shown, the present invention includes a main frame body 1, a feeding mechanism, and a guiding mechanism.

[0032] The feeding mechanism is installed at the upper end of the main frame body 1, and a plurality of guiding mechanisms are installed below the feeding mechanism.

[0033] As Figure 3As shown in the figure, the feeding mechanism includes a feeding belt conveyor 4 and a material distribution assembly. The material distribution assembly includes a material distribution belt conveyor 2 and a rail car 3. The rail car 3 includes a frame 302, rail wheels 303 and a driving device 301. On both sides of the lower end of the frame 302, multiple groups of rail wheels 303 are respectively installed. A driving device 301 is installed on the frame 302. The driving device 301 is connected to the rail wheels 303 through a transmission mechanism. A material distribution belt conveyor 2 is installed at the upper end of the frame 302.

[0034] Two slide rails are installed at the upper end of the main frame body 1. The rail wheels 303 of the rail car 3 are matched with the slide rails.

[0035] As Figure 4 As shown in the figure, a head hopper 9 is installed at the discharge end of the feeding belt conveyor 4. The bulk materials conveyed by the feeding belt conveyor 4 can fall onto the center of the material distribution belt conveyor 2 through the head hopper 9. The head hopper 9 includes a hopper shell 901 and a guide plate 902. The lower half of the hopper shell 901 is provided with an inclined wall. A guide plate 902 is installed on the wall opposite to the inclined wall of the hopper shell 901. The upper end of the guide plate 902 is hinged to the inner wall of the hopper shell 901. A threaded sleeve 905 is installed on the outer wall of the hopper shell 901. A threaded through hole communicating with the cavity of the hopper shell 901 is provided on the threaded sleeve 905.

[0036] The threaded sleeve 905 is matched with a limit screw 904. The limit screw 904 passes through the threaded through hole of the threaded sleeve 905 and is connected to a top block 903. The top block 903 abuts against the back of the guide plate 902. By rotating and adjusting the limit screw 904, the angle of the guide plate 902 can be adjusted, so that the materials can first fall from the feeding belt conveyor 4 onto the guide plate 902 of the head hopper 9, then flow from the guide plate 902 to the inclined wall of the hopper shell 901, and finally fall from the discharge port of the hopper shell 901 onto the material distribution belt conveyor 2.

[0037] The guiding mechanism includes a buffer bin 6 and a telescopic chute 7. A plurality of buffer bins 6 evenly distributed linearly are fixedly installed on the main frame body 1. The discharge port of the buffer bin 6 is connected to the telescopic chute 7 through a discharge gate 8.

[0038] In this embodiment, four buffer bins 6 evenly distributed linearly are fixedly installed on the main frame body 1. The end hoppers at both ends of the material distribution belt conveyor 2 are respectively located directly above the two buffer bins 6. The four buffer bins 6 are divided into two groups. Two non-adjacent buffer bins 6 form a group. The end hoppers at both ends of the material distribution belt conveyor 2 are located directly above one of the groups of buffer bins 6.

[0039] The main frame 1 is respectively equipped with travel switches at both ends of the movement track of the rail vehicle 3. A feeler is installed on the vehicle frame 302 of the rail vehicle 3. When the feeler touches the travel switch, the rail vehicle 3 stops moving, so that the end hoppers at both ends of the material distribution belt conveyor 2 are respectively located directly above the two buffer bins 6. At this time, the material distribution belt conveyor 2 is started, and the bulk cargo material enters the buffer bin 6 from the end hopper at one end of the material distribution belt conveyor 2, and then is input into the container by the buffer bin 6 and the telescopic chute pipe 7. When the container is full, the material distribution belt conveyor 2 is started to make the belt conveyor rotate in the reverse direction, so that the bulk cargo material enters another buffer bin 6 from the end hopper at the other end of the material distribution belt conveyor 2, thereby loading another container.

[0040] When the loading of the two containers under the material distribution belt conveyor 2 is completed, the rail vehicle 3 drives the material distribution belt conveyor 2 to move along the slide rail, so that the material distribution belt conveyor 2 moves directly above the other two buffer bins 6, and then the packing operation is sequentially carried out on the other two containers.

[0041] As Figure 5 shown, the telescopic chute pipe 7 includes a connecting sleeve 701, an inner chute cylinder, a dust removal cloth cylinder 702 and an automatic lifting device. The upper part of the connecting sleeve 701 is provided with a feed inlet, and an inner sleeve is installed at the feed inlet. A dust removal interface is arranged on the side surface of the connecting sleeve 701. The lower part of the connecting sleeve 701 is connected with the dust removal cloth cylinder 702. The lower end of the dust removal cloth cylinder 702 is connected with a discharge pipe 708. The lower end of the inner sleeve is connected with the inner chute cylinder. The inner side of the dust removal cloth cylinder 702 is connected with the inner chute cylinder through a connecting ring 704.

[0042] The connecting sleeve 701 and the discharge pipe 708 are connected through an automatic lifting device. The automatic lifting device includes a pulley 707, a wire rope reel 705 and a reduction motor 706. The outside of the connecting sleeve 701 is provided with a pulley 707 and a wire rope reel 705. The wire rope reel 705 is connected with the reduction motor 706. The wire rope bypasses the pulley 707, and the lower end of the wire rope is fixedly connected with the discharge pipe 708. The dust removal interface is connected with the dust collector 5 through a pipeline, and can suck away the dust generated during the feeding process, thereby reducing the dust pollution.

[0043] The inner chute cylinder is composed of a plurality of conical cylinders 703. The plurality of conical cylinders 703 are sleeved end to end in sequence. The conical cylinder 703 at the uppermost end is fixedly connected with the inner sleeve in the connecting sleeve 701, and the remaining conical cylinders 703 are hinged with the connecting ring 704 so that the conical cylinders 703 can swing.

[0044] As Figure 6As shown in the figure, rotating shafts 711 are respectively installed on both sides of the conical cylinder 703. Two rotating sleeves 712 are symmetrically installed on the connecting ring 704. The rotating sleeve 712 is provided with an axial blind hole. An arc-shaped through hole is provided on the outer wall of the rotating sleeve 712 and communicates with the axial blind hole. The rotating shaft 711 is inserted into the axial blind hole of the rotating sleeve 712 and is rotationally matched therewith. The outer end of the rotating shaft 711 is perpendicularly connected to the limiting shaft 710. The limiting shaft 710 is placed in the arc-shaped through hole of the rotating sleeve 712, so as to be able to limit the rotation angle of the rotating shaft 711.

[0045] In this embodiment, the rotating shafts 711 of two adjacent upper and lower conical cylinders 703 are vertically distributed, so that the rotation directions of the two conical cylinders 703 can be perpendicular, avoiding all conical cylinders 703 deflecting in one direction and interfering with each other.

[0046] A through hole is provided at the center of the dust-proof cover plate 709. A flange is provided at the lower end of the discharge pipe 708. The outer diameter of the flange is larger than the diameter of the through hole of the dust-proof cover plate 709. The lower end of the discharge pipe 708 passes through the through hole of the dust-proof cover plate 709 and the flange abuts against the lower end of the dust-proof cover plate 709. A material level sensor is installed at the lower end of the dust-proof cover plate 709. The material level sensor is connected to the reduction motor 706 through a circuit to automatically lift and lower the telescopic chute 7 according to the loading material level. When the material level sensor contacts the material, a signal is output to control the telescopic chute 7 to rise and stop after rising to a preset height.

[0047] The dust removal interface of the telescopic chute 7 is connected to the dust collector 5 through a pipeline, which can reduce the dust pollution during the material conveying process.

[0048] The operation process is as follows: When loading a container using the device of the present invention, place the container under the four buffer bins 6, start the telescopic chute 7, so that it drives the dust-proof cover plate 709 to buckle at the upper opening of the container. Use the feeding belt conveyor 4 to convey the bulk material to the distributing belt conveyor 2. The distributing belt conveyor 2 buffers the bulk material into the buffer bin 6, and then enters the container through the telescopic chute 7 for loading.

[0049] The present invention further includes an electric control system for controlling the operation steps of the present invention. The electric control system includes a data acquisition device, an information processing module, a control module and a drive circuit relay; the data acquisition device includes a material level sensor, a load-bearing module and a wireless signal transmission module. A pressure sensor is provided on the load-bearing module. The load-bearing module is located at the lower end of the container. The material level sensor and the pressure sensor are connected to the wireless signal transmission module through signal transmission wires. The wireless signal transmission module is wirelessly connected to the information processing module. The information processing module is connected to the control module by wire or wirelessly. The control module is connected to the drive circuit relay by wire or wirelessly. The drive circuit relay is connected to the drive devices of the feeding mechanism and the material guiding mechanism.

[0050] The control method of the container stuffing device by the described control system includes the following steps:

[0051] Step 1: The information processing module sets and records the maximum height H of the container materials max and the maximum mass M max , and waits for the container to complete flipping.

[0052] Step 2: Flip the container. The container is placed on the load-bearing module. The data detected by the pressure sensor is transmitted to the information processing platform through the wireless signal transmission module. The information processing platform analyzes the acquired data to calculate the empty container mass M0 of the container. The control module sends a descending signal to the driving circuit relay to control the telescopic chute 7 to descend until the dust-proof cover 709 at the lower end of the telescopic chute 7 is buckled at the opening of the container. The signal of the level sensor is transmitted to the information processing module through the wireless signal transmission module. The data information platform analyzes and calculates to obtain the empty container height H0 of the container.

[0053] Step 3: After the data collection is completed, the control module transmits signals to the rail car 3 and the discharge gate 8 respectively, controls the discharge gate 8 to open, and makes the rail car 3 drive the distributing belt conveyor 2 to move to the position of the travel switch. At this time, the hoppers at both ends of the distributing belt conveyor 2 are respectively located directly above a group of buffer bins 6. The rail car 3 touches the travel switch, and the travel switch transmits the signal to the control module. The control module transmits the signal to the feeding belt conveyor 4 and the distributing belt conveyor 3 to convey the materials into the container. The level sensor and the pressure sensor monitor the height and mass of the container materials in real time.

[0054] Step 4: When any one of H max and M max reaches the maximum value, the control module sends a stop discharging signal to the driving circuit relay, controls the discharge gate 8 to close, the control module sends a lifting signal to the driving circuit relay, and controls the telescopic chute 7 and the dust-proof cover 709 to be lifted to the initial position to complete the container stuffing operation of this container.

[0055] Step 5: The control module transmits the signal to the distributing belt conveyor 2 to make it rotate in the reverse direction to load materials into the container at the other end. When any one of H max and M max of another container reaches the maximum value, the control module sends a stop discharging signal to the driving circuit relay, controls the discharge gate 8 to close, the control module sends a lifting signal to the driving circuit relay, and controls the telescopic chute 7 and the dust-proof cover 709 to be lifted to the initial position to complete the container stuffing operation of this container, thereby completing the stuffing operation of a group of containers.

[0056] Step 6: The control module transmits a signal to the railcar 3, causing the railcar 3 to drive the material distribution belt conveyor 2 to move above the other two containers. At this time, the railcar touches the travel switch, and the travel switch transmits a signal to the control module. The control module sends a signal to the feeding belt conveyor 4 and the material distribution belt conveyor 2, causing them to repeat Step 4 and Step 5 to complete the loading operation for another group of containers.

[0057] It should be noted that specific embodiments of the present invention have been described in detail. For those skilled in the art, various obvious changes made without departing from the spirit and scope of the present invention are within the protection scope of the present invention.
