[0002] In the process of round steel production and manufacturing, at the beginning when the long round steel enters the cold shearing machine for cutting, the operator needs to dial the incoming round bar into the shearing groove of the lower cutting edge of the cold shearing machine, and press and fix the round bar through the pressure roller to complete the shearing process. When the round bar is initially sheared, sampling and marking are required, and finally, the composition of the round bar is detected to determine whether the composition of the round bar is qualified.

[0003] Currently, the staff holds a receiving box and extends the receiving box into the cold shearing machine on one side of the cutting tool assembly.

[0051] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0052] As Figures 1-11 shown, an embodiment of the present utility model provides an automatic sampling and marking system for steel production, including a sampling and blanking device 2, a conveyor 3, an identification assembly 13, a gripping assembly 14, and a marking assembly 15; the sampling and blanking device 2 is used to take out the cut steel sample from the cold shearing machine 1 and place the steel sample at the starting end of the conveyor 3; the identification assembly 13 is used to identify and position the steel sample at the terminal of the conveyor 3 to obtain the position information of the steel sample; the gripping assembly 14 grabs the steel sample at the terminal of the conveyor 3 according to the position information sent by the identification assembly 13 and places it on the marking assembly 15; the marking assembly 15 is used to mark the steel sample.

[0053] In this embodiment, the sampling and blanking device 2 takes out the cut steel sample from the cold shearing machine 1 and places the steel sample at the starting end of the conveyor 3. The steel sample moves with the conveyor 3 and stops after reaching the terminal position of the conveyor 3. Then, the recognition component 13 recognizes and locates the steel sample to obtain the position information of the steel sample. The grasping component 14 grasps the steel sample at the terminal of the conveyor 3 according to the position information sent by the recognition component 13 and places it at the designated position of the marking component 15, and the marking component 15 performs marking.

[0054] It can be seen that the entire process does not require manual participation, fully realizes automation, eliminates manual sampling, manual handling and transfer of round bars, improves the sampling efficiency, avoids workers from being scalded by round bars during sampling, improves the safety performance, reduces the labor burden of workers, and improves the production efficiency.

[0055] As a preferred embodiment, as Figure 1 and Figure 11 shown, a detection area is formed at the terminal of the conveyor 3, and a first sensor module is installed in the detection area. The recognition component 13 is arranged on the right side of the terminal of the conveyor 3, that is, on the right side of the sixth working station of the conveyor 3. The recognition component 13 includes a vertical frame 131 and a recognition camera 132. The recognition camera 132 is installed on the top of the vertical frame 131, and the recognition camera 132 is located directly above the terminal of the conveyor 3. The recognition camera 132 is aligned with the detection area to obtain the position information of the steel sample in the detection area. The first sensor module is used to detect whether the steel sample enters the detection area at the terminal of the conveyor 3; the control module controls the opening and closing of the conveyor 3 according to the signal input by the first sensor module.

[0056] Specifically, the first sensor module can be any one of an infrared sensor and a proximity switch, as long as it can detect the steel sample entering the detection area. A control box is installed beside the conveyor 3, and the control box includes a PLC control module, a signal receiving unit, a signal sending unit, etc.

[0057] Furthermore, as Figure 11 shown, the grasping component 14 is arranged at the back position of the terminal of the conveyor 3, the marking component 15 is arranged on the left side of the grasping component 14, and a plurality of storage boxes 16 for loading round bar samples are placed on the right side of the marking component 15.

[0058] Specifically, as Figure 11 shown, the grasping component 14 includes a base 1401, a robotic arm 142 and a fixture 143. The robotic arm 142 is installed on the base 1401, and the fixture 143 is detachably installed at the connecting end of the robotic arm 142. Among them, the fixture 143 is a common electromagnetic fixture for grasping round bars, which will not be elaborated here.

[0059] When the steel on the conveyor 3 is conveyed by the conveyor 3 to the detection area at its terminal, at this time, the first sensor module monitors that the steel sample enters the detection area and sends a detection signal to the signal receiving unit of the control box. The PLC control module controls the conveyor 3 to pause operation so that the recognition camera 132 can perform recognition. After the recognition camera 132 recognizes the steel sample in the detection area and obtains the position and attitude information of the steel sample. The PLC control module controls the robotic arm 142 in the grasping assembly 14 to drive the fixture 143 to grasp the steel sample in the detection area and place it on the marking assembly 15. During this process, the fixture 143 does not loosen the steel sample. After the marking is completed, the PLC control module controls the robotic arm 142 in the grasping assembly 14 to drive the fixture 143 to place the marked steel sample on the storage box 16. It should be noted that the position information of the storage box 16 is pre-entered into the control box, so that the marked steel sample can be smoothly placed into the storage box 16.

[0060] Furthermore, the marking assembly 15 includes a marking table 151 and a laser marking machine 152. The tabletop of the marking table 151 is the marking area. The laser marking machine 152 is installed on the marking table 151, and the laser head of the laser marking machine 152 is facing the marking area.

[0061] Optionally, a second sensor module is installed at the starting end of the conveyor 3. The second sensor module is an infrared sensor, which is used to detect whether there is a steel sample at the starting end of the conveyor 3. The PLC control module controls the opening and closing of the conveyor 3 according to the signal input by the second sensor module. In this way, only when the steel sample enters the conveyor 3, the PLC control module will control the conveyor 3 to start. In other cases, the conveyor 3 is in a normally closed state to save power.

[0062] It can be seen that in this embodiment, the automatic marking work of the steel bar sample can be realized, without manual marking, which reduces the labor burden of workers and has high production efficiency.

[0063] Preferably, the steel production sampling transfer system includes a mobile trolley 4. A carrying frame 402 is installed on the mobile trolley 4. A push handle 401 is installed at the front of the mobile trolley 4. The sampling device is installed on the carrying frame 402, and the blanking device 8 is installed on the mobile trolley 4. The mobile trolley 4 can be used to move the sampling device and the blanking device 8, ensuring the flexibility of the sampling and blanking device 2 so as to sample the round bars in other cold shears 1.

[0064] Preferably, as Figure 2As shown in the figure, the sampling and blanking device 2 includes a sampling device and a blanking device 8. The sampling device has a first station and a second station. The blanking device 8 has a third station and a fourth station. The conveyor 3 has a fifth station and a sixth station. The second station is adjacent to the third station, and the fourth station is adjacent to the fifth station. Among them:

[0065] When the sampling device is at the first station, the sampling device is used to receive the steel sample cut in the cold shearer 1. When the sampling device is at the second station, the sampling device is used to turn out the taken steel sample into the blanking device 8 at the third station.

[0066] When the blanking device 8 is at the third station, the blanking device 8 is used to receive the steel sample turned out by the sampling device. When the blanking device 8 is at the fourth station, the blanking device 8 is used to turn out the steel sample onto the fifth station of the conveyor 3, and the conveyor 3 is used to convey the steel sample at the fifth station to the sixth station.

[0067] In this embodiment, the first station of the sampling device is located inside the cold shearer 1, the second station of the sampling device is outside the cold shearer 1 and close to the third station of the blanking device 8, the fifth station of the conveyor 3 is close to the fourth station of the blanking device 8, and the sixth station of the conveyor 3 is close to the laser marking machine 152.

[0068] When sampling and handling round bars, first, the sampling device at the first station receives the steel sample cut in the cold shearer 1, then the sampling device switches to the second station, and the sampling device at the second station turns out the taken steel sample into the blanking device 8 at the third station. After that, the blanking device 8 switches to the fourth station to turn out the steel sample onto the fifth station of the conveyor 3, and the conveyor 3 conveys the steel sample at the fifth station to the sixth station.

[0069] During traditional manual sampling, due to the narrow space inside the cold shearer 1, there are many potential safety hazards during sampling, and safety accidents such as mechanical injuries are likely to occur. In this application, sampling is carried out using the sampling device and the blanking device 8, eliminating the need for manual sampling. The sampling efficiency of round bars is improved, and the risk of workers being scalded by round bars during sampling can be avoided, enhancing the safety performance. Moreover, the sampling device in cooperation with the blanking device 8 can place the taken sample on the conveyor 3, eliminating the need for manual handling and transfer, reducing the labor burden of workers, and improving production efficiency.

[0070] As a preferred embodiment, as Figure 3As shown in the figure, the sampling device includes a linear drive assembly 5, a material receiving box 6, and a first flipping mechanism 7. When the linear drive assembly 5 is in the first working state, the linear drive assembly 5 drives the material receiving box 6 to extend under the cutting tool assembly of the cold shear 1 in the first direction to receive the cut steel; when the linear drive assembly 5 is in the second working state, the linear drive assembly 5 drives the material receiving box 6 to move in the second direction to withdraw from the cold shear 1; the first direction and the second direction are opposite. Specifically, as Figure 1 shown, the first end of the linear drive assembly 5 extends into the interior of the cold shear 1, and its second end is located outside the cold shear 1. The first direction is the direction from the second end to the first end of the linear drive assembly 5, and the second direction is the direction from the first end to the second end of the linear drive assembly 5.

[0071] Furthermore, the first flipping mechanism 7 is installed on the linear drive assembly 5 and is connected to the material receiving box 6. When the first flipping mechanism 7 is in the flipping mode, the first flipping mechanism 7 drives the material receiving box 6 to flip to turn out the steel in the material receiving box 6 and fall into the blanking device 8 at the third working station; when the first flipping mechanism 7 is in the reset mode, the first flipping mechanism 7 drives the material receiving box 6 to return to the upright position.

[0072] In this way, during sampling, first, the linear drive assembly 5 drives the material receiving box 6 to move in the direction close to the cold shear 1 and extend under the cutting tool assembly of the cold shear 1, and the cut steel falls into the material receiving box 6. Then, the linear drive assembly 5 drives the material receiving box 6 to move in the direction away from the cold shear 1 to withdraw from the cold shear 1 to a set position. Immediately afterwards, the first flipping mechanism 7 is adjusted to the flipping mode, so as to drive the material receiving box 6 to flip to turn out the steel in the material receiving box 6 and fall into the blanking device 8 at the third working station. Finally, the first flipping mechanism 7 is switched to the reset mode to drive the material receiving box 6 to return to the upright position for the next sampling operation. Through the mutual cooperation of the linear drive assembly 5, the material receiving box 6, and the first flipping mechanism 7, the automatic sampling work is realized. The whole sampling work is convenient, fast, time-saving, and labor-saving.

[0073] As a preferred embodiment, as Figure 2 shown, a push handle 401 is installed at the front of the mobile trolley 4, the angle of the push handle 401 is adjustable, a carrying frame 402 is installed on the mobile trolley 4 along its length direction, the sampling device is installed on the carrying frame 402, and the blanking device 8 is installed on the mobile trolley 4. In this way, the mobile trolley 4 can be used to move the sampling device and the blanking device 8, ensuring flexibility.

[0074] Preferably, as Figure 3As shown in the figure, the linear drive assembly 5 includes a housing 501, a sliding plate 502, and a drive mechanism. The housing 501 is in the shape of a slender long box. The sliding plate 502 is slidably mounted on the side surface of the housing 501. The drive mechanism is installed inside the housing 501 to drive the sliding plate 502 to move along the length direction of the housing 501. The first flipping mechanism 7 is installed on the sliding plate 502, and one end of the first flipping mechanism 7 is connected to the receiving box 6 to drive the receiving box 6 to rotate. Further, as Figure 2 shown, the housing 501 is detachably mounted on the carrying frame 402 such that the length direction of the housing 501 is consistent with the length direction of the carrying frame 402.

[0075] During sampling, the mobile trolley 4 can be pushed so that the end of the housing 501 in the linear drive assembly 5 extends into the cold shear 1 and approaches one side of the lower tool block of the cutting tool assembly. Subsequently, the drive mechanism drives the sliding plate 502 to drive the receiving box 6 to move towards the cold shear 1, so that the receiving box 6 extends into the interior of the cold shear 1. The upper cutting tool in the cutting tool assembly cooperates with the lower tool block to cut the round bar, and the cut round bar falls into the receiving box 6. As the drive mechanism drives the sliding plate 502 to drive the receiving box 6 to move away from the cold shear 1, the receiving box 6 exits the cold shear 1 and retracts to its original position. In this embodiment, manual sampling is not required, and the automated sampling process can be completed, ensuring the safety of sampling and improving the efficiency of sampling.

[0076] As a preferred embodiment, in this embodiment, as Figure 4 shown, the drive mechanism includes a driving sprocket 509, a driven sprocket 510, a chain, and a first motor 511. Among them, the driving sprocket 509 and the driven sprocket 510 are sequentially rotatably installed inside the housing 501 along the length direction of the housing 501. Specifically, the driving sprocket 509 is rotatably installed at one end of the housing 501 away from the cold shear 1, and the driven sprocket 510 is rotatably installed at one end of the housing 501 close to the cold shear 1. The chain is drivingly installed between the driving sprocket 509 and the driven sprocket 510. The first motor 511 is fixedly installed on the side surface of the housing 501, and the output end of the first motor 511 is connected to the driving sprocket 509. Further, the sliding plate 502 is slidably installed on the right side surface of the housing 501, and a part of the sliding plate 502 is connected to the chain. Again, as Figure 2 shown, the first flipping mechanism 7 is installed on the sliding plate 502, and the first flipping mechanism 7 is connected to the receiving box 6.

[0077] When the driving mechanism drives the sliding plate 502 to move along the length direction of the housing 501, the first motor 511 drives the driving sprocket 509 to rotate. Since the chain drive is installed between the driving sprocket 509 and the driven sprocket 510, the chain rotates. And the sliding plate 502 is connected to the chain, so that the sliding plate 502 moves along the length direction of the housing 501 as the chain rotates, and the material receiving box 6 moves as the sliding plate 502 moves.

[0078] As an optional embodiment, in order to ensure that the sliding plate 502 can slide stably on the housing 501 and reduce the friction between the sliding plate 502 and the housing 501, an upper hole body and a lower hole body are successively formed along the length direction on the side plate 512 on the right side of the housing 501. The widths and lengths of the upper hole body and the lower hole body are the same. Both the upper hole body and the lower hole body are long holes. The length of the upper hole body and the lower hole body is slightly less than the length of the front panel 301. The upper hole body is located above the lower hole body. Further, a bearing rail one 503 is installed on the inner bottom wall of the upper hole body, and a bearing rail two 504 is installed on the inner bottom wall of the lower hole body. The bearing rail one 503 and the bearing rail two 504 are exactly the same. The length of the bearing rail one 503 is slightly less than the length of the upper hole body.

[0079] Further, as Figure 5 and Figure 6 shown, a wheel one 513 and a wheel two 515 are installed on the back surface of the sliding plate 502. The wheel one 513 is located above the wheel two 515. The distance between the bearing rail one 503 and the bearing rail two 504 is the same as the distance between the wheel one 513 and the wheel two 515. When installing the sliding plate 502, the wheel one 513 on the back surface of the sliding plate 502 can be installed on the bearing rail one 503, and at the same time, the wheel two 515 can be installed on the bearing rail two 504.

[0080] It should be noted that the cross sections of the bearing rail one 503 and the bearing rail two 504 are in a convex shape. Both the wheel one 513 and the wheel two 515 include a shaft body and wheel rims on both sides of the shaft body. The inner walls of the two wheel rims on the wheel one 513 are attached to both sides of the top of the bearing rail one 503, and the inner walls of the two wheel rims on the wheel two 515 are attached to both sides of the top of the bearing rail two 504. In this way, the friction between the sliding plate 502 and the housing 501 can be changed into rolling friction, reducing the frictional force and improving the moving efficiency. Second, the roller cannot be separated from the bearing rail, so as to hold the sliding plate 502 and prevent the sliding plate 502 from being separated from the housing 501.

[0081] Optionally, as Figure 6 shown, a connecting piece 514 is installed on the back surface of the sliding plate 502. The connecting piece 514 is at the same height as the wheel one 513. The connecting piece 514 is used to connect to the chain.

[0082] To facilitate the dumping of the steel in the receiving box 6 so as to dump the steel onto the blanking device 8. Preferably, as Figure 5 shown, a first tipping mechanism 7 is installed on the front of the sliding plate 502. The first tipping mechanism 7 includes a second motor 701, a coupling 702 and a drive shaft 703. Among them, the second motor 701 is fixedly installed on the front of the sliding plate 502 through an L-shaped angle seat. A rectangular frame is fixedly installed on the front of the sliding plate 502. Bearings are installed on both sides of the left side of the rectangular frame respectively. The drive shaft 703 passes through the two bearings. One end of the drive shaft 703 close to the second motor 701 is connected to the output end of the second motor 701 through the coupling 702. One end of the drive shaft 703 close to the receiving box 6 is detachably connected to the receiving box 6 through a flange member.

[0083] In this way, when it is necessary to dump the round steel in the receiving box 6, the second motor 701 drives the coupling 702 and the drive shaft 703 to rotate, and finally drives the receiving box 6 to rotate together to turn out the round steel in the receiving box 6.

[0084] To better detect whether the receiving box 6 extends into the set position of the cold shear 1, as Figure 3 shown, a proximity switch 508 is installed at the top of one end of the housing 501 extending into the cold shear 1, and a signal trigger 507 is installed at the top position on the front of the sliding plate 502. In this way, when the sliding plate 502 drives the receiving box 6 to move towards the inside of the cold shear 1 to the set position, at this time the signal trigger 507 just moves to the proximity switch 508, and the proximity switch 508 quickly issues an electrical instruction, and the controller controls the first motor 511 to pause so that the receiving box 6 can just receive all the cut round steel.

[0085] Optionally, as Figure 3 shown, a drag chain carrier frame 505 for accommodating the drag chain 506 is installed on the top of the housing 501 along its length direction. A drag chain connecting piece in the shape of an inverted L-shaped plate is installed on the sliding plate 502. One end of the drag chain 506 in the drag chain carrier frame 505 is connected to the drag chain connecting piece. The drag chain 506 is used to induct signal wires.

[0086] To automatically place the round bar sample in the receiving box 6 onto the conveyor 3, a blanking device 8 is specially installed on the right side of the mobile trolley 4. The blanking device 8 receives the round steel sample in the receiving box 6 and places the round steel sample onto the conveyor 3. As Figure 8As shown in the figure, the blanking device 8 includes a blanking hopper 9, a second flipping mechanism 12, and a linear guide mechanism 11; the linear guide mechanism 11 includes a guide rail mechanism and a driving device. The guide rail mechanism is inclined and lower than the receiving box 6. The first end of the guide rail mechanism is close to the receiving box 6, and the first end of the guide rail mechanism is lower than its second end; both the blanking hopper 9 and the second flipping mechanism 12 are slidably mounted on the guide rail mechanism; when the blanking hopper 9 is in the third working position, the blanking hopper 9 is located at the first end of the guide rail mechanism; when the blanking hopper 9 is in the fourth working position, the blanking hopper 9 is located at the second end of the guide rail mechanism; the driving device is used to drive the blanking hopper 9 to switch between the third working position and the fourth working position; the second flipping mechanism 12 has a first working state and a second working state. When the second flipping mechanism 12 is in the first working state, the second flipping mechanism 12 drives the blanking hopper 9 in the fourth working position to flip so as to turn out the steel in the blanking hopper 9 onto the fifth working position of the conveyor 3; when the second flipping mechanism 12 is in the second working state, the second flipping mechanism 12 drives the blanking hopper 9 in the third working position to return to the upright position to receive the steel sample turned out by the receiving box 6.

[0087] Specifically, when the blanking hopper 9 is in the third working position, the blanking hopper 9 is located at the first end of the guide rail mechanism. At this time, the blanking hopper 9 is located below the receiving box 6 and is used to carry the steel sample turned out by the receiving box 6. The driving device can drive the blanking hopper 9 to switch between the third working position and the fourth working position, so as to drive the blanking hopper 9 to gradually approach the conveyor 3 and its height is also continuously increasing. Finally, the blanking hopper 9 moves to the second end of the guide rail mechanism. At this time, the blanking hopper 9 is close to the fifth working position of the conveyor 3 and is higher than the fifth working position of the conveyor 3. Then, the second flipping mechanism 12 drives the blanking hopper 9 in the fourth working position to flip so as to turn out the steel in the blanking hopper 9 onto the fifth working position of the conveyor 3, and then the conveyor 3 conveys the steel at the fifth working position to the sixth working position of the conveyor 3. At the same time, the driving device drives the blanking hopper 9 in the fourth working position to switch to the third working position, so that the blanking hopper 9 moves to the first end of the guide rail mechanism. Then, the second flipping mechanism 12 drives the blanking hopper 9 in the third working position to return to the upright position to continue receiving the steel sample turned out by the receiving box 6. Therefore, the blanking device 8 in this embodiment plays a role in transporting and transferring the steel sample, so as to smoothly transfer the steel sample to the conveyor 3 without manually transporting the steel sample in the receiving box 6 to the conveyor 3, improving the production efficiency.

[0088] As Figure 7 shown, a notch is formed at the middle position on the right side of the moving trolley 4. Plate bodies are respectively fixed on the front and rear inner walls of the notch, and a bracket assembly 10 is installed between the two plate bodies. The linear guide mechanism 11 is installed on the bracket assembly 10. Specifically, as Figure 8As shown in the figure, the support assembly 10 includes two support plates 1001 and two fixing rods 1002. The two support plates 1001 are right-angled triangular plates. The two support plates 1001 are respectively fixed on two plate bodies in the notch by bolts, and the inclined surfaces of the support plates 1001 face upward, that is, from the left side to the right side of the moving trolley 4, the left end of the support plate 1001 is lower than its right end. The two fixing rods 1002 are fixedly installed between the two support plates 1001 and are used to connect the two support plates 1001 to enhance the stability of the support assembly 10.

[0089] As Figure 8 shown, the linear guide rail mechanism 11 includes a first cylinder 1105, two moving plates 1103, two guide rails 1101 and a connecting pipe 1104. The two guide rails 1101 are respectively fixedly installed on the top inclined surfaces of the two support plates 1001 so that the guide rails 1101 are inclined. Two sliding seats 1102 are slidably installed on each guide rail 1101. The two sliding seats 1102 on each guide rail 1101 are connected by a moving plate 1103. The top of the sliding seat 1102 is fixedly connected to the moving plate 1103. One end of the connecting pipe 1104 is fixed to the right end of one moving plate 1103, and the other end is fixed to the right end of the other moving plate 1103.

[0090] Furthermore, as Figure 10 shown, the first cylinder 1105 is installed on a fixing rod 1002 through a mounting seat, and the other end is connected to the connecting pipe 1104. The blanking hopper 9 is rotatably installed between the two moving plates 1103. The second flipping mechanism 12 is installed on one moving plate 1103 and is used to drive the blanking hopper 9 to flip.

[0091] In this way, when the receiving box 6 in the sampling device retracts to the set position, at this time the receiving box 6 is aligned with the blanking hopper 9, achieving as Figure 2The state shown. After that, the first cylinder 1105 extends to push the connecting pipe 1104. Since the two moving plates 1103 are fixed to each other through the connecting pipe 1104, and the moving plates 1103 are slidably mounted on the track 1101 through the sliding seats 1102, when the first cylinder 1105 extends, it will push the moving plates 1103 to move to the right side of the track 1101 along the track 1101. And the hopper 9 is installed between the two moving plates 1103, so it will also move to the right side of the track 1101, causing the hopper 9 to gradually approach the conveyor 3, and the height of the hopper 9 to gradually increase until the hopper 9 moves above the conveyor 3, or the right side of the hopper 9 is above the conveyor 3. Then the second flipping mechanism 12 drives the hopper 9 to rotate to adjust the inclination angle of the hopper 9, making the left side of the hopper 9 higher than the right side, so that the round steel in the hopper 9 will smoothly roll from the hopper 9 onto the conveyor 3. Such a transfer has high efficiency, is convenient to operate, and saves time and effort.

[0092] As a preferred embodiment, as Figure 9 shown, the second flipping mechanism 12 includes a flipping shaft, two support seats 1201, a curved rod 1202, a second cylinder 1203 and a hinge seat 1204. Among them, the two support seats 1201 are respectively installed on the two moving plates 1103. The support seats 1201 are in the shape of inclined plates, and the angle formed between the support seats 1201 and the moving plates 1103 is an acute angle. The hinge seat 1204 is installed on the moving plate 1103 in front of the hopper 9. The first end of the curved rod 1202 is connected to the flipping shaft, one end of the second cylinder 1203 is hinged to the hinge seat 1204, and the other end is hinged to the second end of the curved rod 1202. The bottom of the hopper 9 is fixedly connected to the flipping shaft.

[0093] In this way, as the driving mechanism drives the sliding plate 502 to drive the receiving box 6 to move away from the cold shear 1, the receiving box 6 is withdrawn from the cold shear 1 and retracted to its original position, that is, the receiving box 6 is in the second working position and retracted to as Figure 2The state shown is such that the material receiving box 6 is higher than the material discharging hopper 9 at this time, and the material discharging hopper 9 and the material receiving box 6 are opposite to each other. Then the second motor 701 drives the drive shaft 703 to rotate, thereby driving the material receiving box 6 to rotate clockwise by a set angle, so that the round steel in the material receiving box 6 rolls down from the material receiving box 6 and falls into the material discharging hopper 9 at the third station. Immediately afterwards, the first cylinder 1105 extends to push the moving plate 1103 to move towards the right side of the track 1101 on the track 1101, so that the material discharging hopper 9 gradually approaches the conveyor 3 while the height of the material discharging hopper 9 gradually increases. Until after the material discharging hopper 9 moves above the conveyor 3, that is, the material discharging hopper 9 moves to the fourth station, the first cylinder 1105 pauses working. Immediately afterwards, the second cylinder 1203 extends so that the curved rod 1202 drives the rotating shaft 302 to rotate clockwise, thereby causing the material discharging hopper 9 to rotate clockwise until the left side of the material discharging hopper 9 is higher than its right side, so that the round steel in the material discharging hopper 9 can roll down along the material discharging hopper 9 onto the starting end of the conveyor 3, that is, the fifth station of the conveyor 3. Subsequently, the first cylinder 1105 shortens to pull the material discharging hopper 9 back to the third station, and then the second cylinder 1203 shortens to pull the curved rod 1202 to drive the rotating shaft 302 to rotate counterclockwise, thereby causing the material discharging hopper 9 to rotate counterclockwise, and the material discharging hopper 9 gradually assumes a material receiving state. Finally, the conveyor 3 transports the steel sample from the fifth station to its sixth station, that is, near the laser marking machine 152.

[0094] It can be seen that the sampling device and the material discharging device 8 are used in cooperation. There is no need for manual sampling, the sampling efficiency of the round bar is improved, and it can avoid workers being scalded by the round bar during sampling, so the safety performance is improved. Moreover, the sampling device cooperates with the material discharging device 8 to automatically place the taken sample onto the conveyor 3, realizing automatic sampling and automatic material discharging operations. Finally, the conveyor 3 transports the sample to the laser marking machine 152. Throughout the process, there is no need for manual handling and transfer, which reduces the labor burden of workers and improves production efficiency.

[0095] Optionally, as Figure 9 and Figure 10 shown, a rectangular plate 1106 is installed at the middle position of the connecting pipe 1104. A round hole for the output end of the first cylinder 1105 to pass through is provided near the bottom of the rectangular plate 1106. External threads are provided on the outer side surface of the output end of the first cylinder 1105. After the output end of the first cylinder 1105 passes through the round hole on the rectangular plate 1106, a nut is used to fix the output end of the first cylinder 1105 to the rectangular plate 1106.

[0096] Optionally, as Figure 6 shown, mounting holes are formed at the top of each support seat 1201. Bearings are installed in the mounting holes, and end covers are provided on the outside of the support seat 1201 to cover the bearings. Both ends of the rotating shaft are respectively connected to the bearings on the two support seats 1201 in a matching manner.

[0097] It should be noted that the first motor 511, the second motor 701, the first cylinder 1105, and the second cylinder 1203 are all controlled by the PLC control module to control the operation of the first motor 511, the second motor 701, the first cylinder 1105, and the second cylinder 1203, so as to realize the programmed sampling and blanking work.
