[0013] The waste processing unit also includes an automatic waste collection unit, and a waste counting module and a weight monitoring module are arranged inside the automatic waste collection unit.

[0014] Preferably, the waste counting module is MES counting, and the weight monitoring module is weighbridge monitoring.

[0015] Preferably, the next step of the waste counting module and the weight monitoring module is provided with a waste frame full frame processing unit; the waste frame full frame processing unit can monitor whether the waste frame is full;

[0016] The automatic collection, transfer and loading system of scrap steel cut by flying shears in steel rolling mills also includes a tipping device, which is a steel tipping machine.

[0017] Preferably, the forklift movement processing and scheduling unit can control a plurality of forklifts to perform movement scheduling in sequence.

[0036] See also Figure 1-6 , the present invention provides a technical solution: a system for automatically collecting, transporting and loading scrap steel by flying shears of steel rolling mills, including a scrap processing unit, an early warning sensing and fault processing unit and a forklift mobile processing and dispatching unit, wherein the scrap processing unit includes a scrap cutting and shredding device for steel rolling mills;

[0037] The output end signal of the waste processing unit is connected to the automatic waste collection unit, the automatic waste collection unit signal is connected to the full-frame waste processing unit, the forklift mobile processing scheduling unit is connected to the early warning sensing and fault processing unit signal, the forklift mobile processing scheduling unit signal is connected to the forklift automatic charging unit, the forklift mobile processing scheduling unit signal is connected to the overhead crane automatic adsorption processing unit, the steel rolling head and tail cutting equipment is an existing flying shear device, which can cut the head and tail of the produced steel to ensure the quality of the steel, the waste is collected from the flying shear chute and enters the waste frame, and the flying shear cut scrap steel enters the waste frame from the flying shear chute, the forklift mobile processing scheduling unit includes a forklift automatic charging unit, and the forklift automatic charging unit can make instructions through the signal sent by the forklift mobile processing scheduling unit to move the forklift along a predetermined route for charging;

[0038] Among them, the waste processing unit also includes an automatic waste collection unit, which is internally provided with a waste counting module and a weight monitoring module. The waste counting module is MES counting, and the weight monitoring module is floor scale monitoring. The next step of the waste counting module and the weight monitoring module is provided with a waste frame full frame processing unit; the automatic collection, transportation and loading system of scrap steel for flying shear cutting, tail cutting and crushing in the steel rolling mill also includes a tilting device, which is a steel turning machine.

[0039] Embodiment 1:

[0040] When the automatic collection, transfer and loading system of scrap steel cut by flying shear in the steel rolling mill is in operation, the flying shear device will first perform flying shearing, which can cut the head and tail of the produced steel to ensure the quality of the steel. The waste is collected from the flying shear chute and enters the waste frame. At the same time, the scrap steel cut by the flying shear enters the waste frame from the flying shear chute.

[0041] When the single station is full:

[0042] When it is detected that the waste frame is full, the shear chute baffle is closed and a signal is sent to the forklift mobile processing and scheduling unit. The forklift mobile processing and scheduling unit includes an AGV forklift and a forklift automatic charging unit. At this time, the AGV forklift that receives the signal moves to receive the full waste frame. The AGV forklift drives the full waste frame to move away, and the second AGV forklift places the new waste frame at the designated position to receive the waste again.

[0043] Furthermore, when the full scrap frame is moved and the data of the scale on which the scrap frame is placed is reset, the baffle of the shear chute is still blocked. When a new scrap frame is placed, the scale detects the weight. At this time, the system opens the baffle to allow the waste to fall, thereby avoiding the baffle blocking the full warehouse in the shear chute for a long time and causing danger.

[0044] Furthermore, scrap counting can measure the amount of scrap to avoid the scrap box being full, and weight monitoring can monitor some residual broken scrap steel to avoid the situation where the scrap box is full when the scrap meter is not full due to a large amount of broken scrap steel, and the AGV forklift cannot feel the weight, causing the forklift arm to break, thereby ensuring safety.

[0045] When the AGV forklift drives the full waste frame to move away, the full waste frame will be cooled and placed for one hour, and a waste discharge task to the steel turning machine will be generated. After taking over, the AGV forklift will take the full frame and transport it to the steel turning machine. Before arriving at the steel turning machine, the AGV forklift will stop and give an entry request to the steel turning machine. The steel turning machine determines that it can be docked and gives permission to enter. The AGV forklift puts the full frame on the steel turning machine and then exits, gives a departure signal, and the steel turning machine starts to turn the steel. During the steel turning process, the AGV forklift will wait outside for the steel turning machine to give a signal to end turning. After turning the steel, the empty frame will be taken away and sent to the cache position next to the flying shear mouth. When the AGV forklift takes the empty frame, it will send a request to enter the frame-taking signal. The steel turning machine will send a permission to enter signal after determining that the conditions are met. When the AGV forklift finishes taking and leaving, it will send a departure signal to the steel turning machine. All processes are reset and wait for the next docking. After the steel turning device turns the scrap steel three times, the waste will be returned to the waste frame.

[0046] Further, after the AGV forklift transports the waste frame to a designated position under the automatic adsorption processing unit of the overhead crane, a signal is sent to the automatic adsorption processing unit of the overhead crane;

[0047] After receiving the information, the overhead crane automatically identifies the parking space and performs fully automatic loading when the vehicle meets the loading conditions. After loading is completed, a vehicle transportation signal is issued, and the AGV forklift returns with an empty waste frame.

[0048] Furthermore, when the overhead crane automatic adsorption processing unit processes the waste frame, a visual camera is used to locate, identify the position of the AGV forklift and the position of the vehicle, so as to facilitate the operation of the overhead crane.

[0049] The early warning sensing and fault handling unit can monitor the recognition errors of the scrap counting and weight monitoring modules, and can promptly issue an alarm warning through a buzzer to allow workers to come over to check or shut down the machine for processing, thereby avoiding problems with the scrap frame during collection. At the same time, the early warning sensing and fault handling unit is electrically connected to the factory camera where the forklift is located, and can detect situations such as a forklift stopping due to a fault when moving along the designated route (for example, scrap steel falls onto the track and the forklift stops moving forward), resulting in a rear-end collision with the following vehicle, thereby increasing safety.

[0050] Embodiment 2:

[0051] When the automatic collection, transfer and loading system of scrap steel cut by flying shear in the steel rolling mill is in operation, the flying shear device will first perform flying shearing, which can cut the head and tail of the produced steel to ensure the quality of the steel. The waste is collected from the flying shear chute and enters the waste frame. At the same time, the scrap steel cut by the flying shear enters the waste frame from the flying shear chute.

[0052] When multiple stations are full: When it is detected that the waste in the waste frame reaches the waste discharge standard, the centralized control center issues a task, and the AGV forklift arrives at the waiting position for the shear unloading after receiving the task. (When multiple tasks are issued, the AGV forklifts execute them in sequence, and each AGV forklift changes the frame independently at each shear unloading port without interfering with each other) (The execution process is the same as the single-station full-frame task).

[0053] Furthermore, when the full scrap frame is moved and the data of the scale on which the scrap frame is placed is reset, the baffle of the shear chute is still blocked. When a new scrap frame is placed, the scale detects the weight. At this time, the system opens the baffle to allow the waste to fall, thereby avoiding the baffle blocking the full warehouse in the shear chute for a long time and causing danger.

[0054] Furthermore, scrap counting can measure the amount of scrap to avoid the scrap box being full, and weight monitoring can monitor some residual broken scrap steel to avoid the situation where the scrap box is full when the scrap meter is not full due to a large amount of broken scrap steel, and the AGV forklift cannot feel the weight, causing the forklift arm to break, thereby ensuring safety.

[0055] When the AGV forklift drives the full waste frame to move away, the full waste frame will be cooled and placed for one hour, and a waste discharge task to the steel turning machine will be generated. After taking over, the AGV forklift will take the full frame and transport it to the steel turning machine. Before arriving at the steel turning machine, the AGV forklift will stop and give an entry request to the steel turning machine. The steel turning machine determines that it can be docked and gives permission to enter. The AGV forklift puts the full frame on the steel turning machine and then exits, gives a departure signal, and the steel turning machine starts to turn the steel. During the steel turning process, the AGV forklift will wait outside for the steel turning machine to give a signal to end turning. After turning the steel, the empty frame will be taken away and sent to the cache position next to the flying shear mouth. When the AGV forklift takes the empty frame, it will send a request to enter the frame-taking signal. The steel turning machine will send a permission to enter signal after determining that the conditions are met. When the AGV forklift finishes taking and leaving, it will send a departure signal to the steel turning machine. All processes are reset and wait for the next docking. After the steel turning device turns the scrap steel three times, the waste will be returned to the waste frame.

[0056] Further, after the AGV forklift transports the waste frame to a designated position under the automatic adsorption processing unit of the overhead crane, a signal is sent to the automatic adsorption processing unit of the overhead crane;

[0057] After receiving the information, the overhead crane automatically identifies the parking space and performs fully automatic loading when the vehicle meets the loading conditions. After loading is completed, a vehicle transportation signal is issued, and the AGV forklift returns with an empty waste frame.

[0058] Furthermore, when the overhead crane automatic adsorption processing unit processes the waste frame, a visual camera is used to locate, identify the position of the AGV forklift and the position of the vehicle, so as to facilitate the operation of the overhead crane.

[0059] The early warning sensing and fault handling unit can monitor the recognition errors of the waste counting and weight monitoring modules, and can promptly issue an alarm warning through a buzzer to allow workers to come over to check or shut down the machine for processing, thereby avoiding problems with the waste frame during collection. At the same time, the early warning sensing and fault handling unit is electrically connected to the factory camera where the forklift travels, and can monitor the forklift's malfunction and stop when moving along the designated route, resulting in rear-end collisions, etc., thereby increasing safety.

[0060] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
