The bulk material processing system includes an unloading unit 10 , a storage warehouse 20 , a loading unit 30 , a traveling unit 40 , an obstacle avoidance unit 50 and a control unit 60 . The unloading unit 10 is used for receiving the materials transported by the external conveying means, and unloading the materials for temporary storage. The storage warehouse 20 is used for receiving materials from the unloading unit 10, and can perform processing such as water filtration, aging and the like on the materials. The loading unit 30 is used for receiving materials from the storage warehouse 20 in response to the material demand required for the production of the downstream production line. The obstacle avoidance unit 50 can detect the intrusion objects of the unloading unit 10 and the loading unit 30 , and feed back corresponding detection signals to the control unit 60 . The control unit 60 is connected in communication with the unloading unit 10 , the loading unit 30 , the traveling unit 40 , and the obstacle avoidance unit 50 , and can control the operation of the electrified equipment in the above-mentioned units.

The storage warehouse 20 is located between the unloading unit 10 and the loading unit 20 . The storage warehouse 20 includes a plurality of storage bins 21 . The upper part of the storage silo 21 is open, so that the traveling unit 40 can transfer the material temporarily stored in the unloading silo 12 of the unloading unit 10 to the corresponding storage silo 21 and transfer the material in the storage silo 21 Then transfer to the feeding unit 30. A plurality of the storage bins 21 are arranged in a matrix, so as to plan the travel path of the traveling unit 40 . At the same time, it is also convenient to manage the relevant information of the storage bins 21. For example, different codes are used for the storage bins 21. The storage bins 21 in different rows and columns can be used to store different types of materials, material source, storage time, The standby state (for example, whether it has been pre-processed, and can be put into the feeding unit 30 online) can also be associated with the storage silo 21 to provide basic information for automatic picking and placing of materials.

The storage silo 21 can be equipped with a water filter board and other equipment for pre-processing the materials before going online.

The loading unit 30 includes a loading bin 31 . The loading bin 31 is used to receive the materials from the storage bin 21 and release the materials to the production line according to the production needs of the downstream production line. In one embodiment, the unloading bin 12, the storage bin 21, and the loading bin 31 are arranged in a linear order. For example, the three are arranged in a straight line, and the storage bin 21 is located between the unloading bin 12 and the loading bin 31 .

In one embodiment, a material level sensor 311 is set in the loading bin 31 . There may be a plurality of material level sensors 311, which are respectively located at different depths of the silo body of the upper silo 31, so as to detect the material remaining in the upper silo 31 in real time. For example, the upper material bin 31 has a cone-shaped structure with a large upper and a small lower, and a plurality of material level sensors 311 are arranged in sequence and spaced along the generatrix of the cone. The material level sensor 311 is connected in communication with the control unit 60 and the second sub-controller 32 , and provides corresponding detection signals for the control instructions of the second sub-controller 32 and the control unit 60 .

In one embodiment, a vibrator 312 is further arranged in the upper bin 31 . The vibrator 312 is arranged at the bottom or top of the bin body of the upper bin 31 . The vibrator 312 can vibrate the silo body when the material is released, so that the material in the upper silo 31 can be completely released and the material will not be retained in the upper silo 31 due to the resistance of the silo wall. The vibrator 312 can also be connected in communication with the second sub-controller 32 and the control unit 60, and is turned on when the loading bin 31 is in a state of releasing materials.

The traveling unit 40 includes a traveling beam 41 , a traveling vehicle 42 , a grabber 43 , a third sub-controller 44 and a scanner 45 .

The walking beam 41 is erected in the area where the unloading unit 10 , the storage warehouse 20 , and the loading unit 30 are located, that is, the extended length of the walking beam 41 extends to the area where the above-mentioned units are located. The traveling vehicle 42 is arranged on the traveling beam 41 and can move along the extending direction of the traveling beam 41 (hereinafter referred to as the longitudinal direction) above the area where the unloading unit 10 , the storage warehouse 20 and the loading unit 30 are located. The gripper 43 is arranged on the carriage 42 and can follow the carriage 42 to move in the longitudinal direction. At the same time, the grabber 43 can also move laterally along the carriage 42 to align the corresponding unloading bin 12, store The silo 21 and the upper silo 31. The gripper 43 can also perform lifting motions in the direction of gravity, as well as opening and closing motions. The gripper 43 moves between the unloading bin 12, the storage bin 21 and the loading bin 31 to transfer the material from the unloading bin 12 to the storage bin 21, which can transfer the material from the storage bin 21 to the loading bin Warehouse 31.

The third sub-controller 44 is connected in communication with the control unit 60 for controlling the movement of the carriage 42 and the grabber 43 . The third sub-controller 44 receives the instructions from the control unit 60, controls the crane 42 and the grabber 43 to run above the unloading bin 12, and then uses the grabber 43 to descend, open, close, and ascend to complete the grabbing of the material , and then control the crane 42 to run above the corresponding storage silo 21, and then use the gripper 43 to descend, open, close and rise to complete the release of the material, so as to transfer the material from the unloading silo 12 to the storage silo twenty one. Similarly, the action of transferring materials from the storage bin 21 to the loading bin 31 can also be completed.

The scanner 45 is arranged on the carriage 42 and can move together with the carriage 42 . In some embodiments, the scanner 45 can also be arranged on the same carrier as the gripper 43 so as to follow the gripper 43 to move in the longitudinal and lateral directions, so that the scanner 45 can scan below the corresponding position of the gripper 43 For example, the information of the materials in the unloading bin 12 can be scanned, the information of the materials in the storage bin 21 can also be scanned, and the information of the materials in the loading bin 31 can also be scanned if necessary. The scanner 45 is connected in communication with the control unit 60 for providing relevant detection information to the control unit 60 and providing a basis for the control instruction sent by the control unit 60 to the grabber 43 and the like.

More than one type of scanner 45 may be provided depending on the function that the scanner 45 needs to implement. For example, the scanner 45 may be a contour scanner for acquiring the stock of material in the storage silo 21 . By scanning the three-dimensional contour of the material in the storage silo 21, the contour scanner can know the shape, height, size and other information of the material stacked in the storage silo 21, and then calculate the volume of the material in the corresponding storage silo 21, Knowing the volume of a specific material is equivalent to obtaining information such as the weight of the material, and then specifying the material storage in the corresponding storage bin 21 . After the control unit 60 obtains the material storage capacity of each storage bin 21, it can control the grabber 43 to grab in the corresponding storage bin 21. For example, the control unit 60 can control the transfer from the storage bin 21 to the loading bin 31. The action avoids the storage bins 21 whose current reserves are insufficient and selects storage bins 21 with sufficient reserves. At the same time, the control unit 60 can control the action of transferring from the unloading bin 12 to the storage bin 21 to preferentially release the material in the storage bin 21 with insufficient remaining space, and avoid selecting the storage bin 21 with insufficient remaining space.

The scanner 45 may also be a species scanner for capturing the type of material in the discharge bin 12 . The species scanner can determine the properties and types of materials in the unloading bin 12 by comparing the captured photos of the materials with the existing photos in the database. After the control unit 60 acquires the material type, it can control the material grabber 43 to grab the material and put it into the corresponding storage bin 21 . For example, different kinds of materials are respectively placed in the plurality of storage bins 21 . The types of materials placed in each storage bin 21 are relatively fixed. When the species scanner learns that the material in the unloading bin 12 is sand, the control unit 60 controls the grabber 43 to grab the material and put it into the storage bin 21 for storing sand. When the species scanner learns that the material in the unloading bin 12 is broken glass, the control unit 60 will control the grabber 43 to grab and put it into the storage bin 21 where the broken glass is stored.

It can be understood that the information acquisition of the material type can be achieved by other non-scanning means. For example, in some embodiments, the material type can also be fed back to the control unit 60 by manually inputting the material type in the operation station 13 when the conveyance means unloads the material into the dump truck 111 .

The scanner 45 may also be a silo information scanner, which is used to obtain the encoded information of the storage silo 21 . The encoded information may include a record of information such as the physical space location of the storage bin 21, the type of the stored material, and the source of the material. For example, a specific storage silo 21 itself is associated with a specific physical space location, and can also be further associated with the type of material stored and the source of the material, that is, a certain material provided by a certain manufacturer is stored in a specific storage silo 21, so By describing the coded information of the storage bin 21, the type of material, the source of the material, and the specific physical space that the traveling unit 40 needs to reach when accessing the material can be known. In some embodiments, the control unit 60 can learn the relevant information of the incoming material by manually inputting the material type and source in the operation console 13 , so as to match the coding information of the storage bin 21 , and then control the traveling unit 40 Take corresponding action.

The coding information can also include records of material storage time, material standby status and other information. For example, when the material is released in a specific storage bin 21, the time can be recorded, and then the time interval of the previous release of the material can be known when the material is released next time, and the time when the material in the storage bin 21 was placed can be known. Similarly, through the material storage time, it can be known whether the standby status of the material meets the needs. For example, a specific material type needs to be placed for a specific time to filter the material. When the corresponding time is reached, it can be determined that the water filtering operation is completed, and the materials in the storage silo 21 can be allowed to enter the feeding unit 30 for use.

The traveling vehicle 42 is also provided with a limit detection sensor 441 , a distance detection sensor 442 and an encoder 445 for providing detection information for the positioning of the grabber 43 . The limit detection sensors 441 are arranged at both ends of the traveling vehicle 42 , and the limit position of the lateral movement of the gripper 43 on the traveling vehicle 42 can be detected by the limit detection sensors 441 and provide detection information to the third sub-controller 44 and the control unit 60 .

The distance detection sensor 442 can detect the lateral and longitudinal movement distances of the gripper 43 and provide detection information to the third sub-controller 44 and the control unit 60 . The distance detection sensor 442 includes a longitudinal distance detection sensor 443 and a lateral distance detection sensor 444 . Two longitudinal distance detection sensors 443 may be provided, respectively on the side of the unloading unit 10 and the loading unit 30 away from the storage warehouse 20 , to detect the moving distance and position of the carriage 42 and the grabber 43 in the longitudinal direction. Two lateral distance detection sensors 444 may also be provided, which are located at the two ends of the traveling vehicle 42 respectively, to detect the moving distance and position of the grabber 43 in the lateral direction.

The encoder 445 can convert the moving distance of the gripper 43 in the horizontal, vertical and gravity directions into electrical signals, and provide it to the third sub-controller 44 and the control unit 60 to provide the control unit 60 to control the action of the gripper 43 . in accordance with.
