However, since there are inevitably burrs on the surface of the bars, during the heating process, the burrs melt, which will cause the transported bars to stick together, affecting subsequent transportation and normal processes.

[0003] The Chinese patent application with the application number 2021106745770 discloses an anti-sticking conveying device for heating furnace heating bars. A conveying chain is provided above the base. On both sides above the conveying chain, a multi-edge roller is longitudinally provided at one end in the input direction of the conveying chain. An auxiliary separation device is provided above the conveying chain and the multi-edge roller. The auxiliary separation device includes a bracket, a pressing cylinder is provided on the bracket, a connecting plate is provided at the end of the pressing cylinder, a separating pressing rod and an elastic positioning pressing rod are provided on the connecting plate. The separating pressing rod is arranged above the conveying chain, and the elastic positioning pressing rod is arranged above the multi-edge roller. By pressing the bars without discrimination, the separation of the stuck bars is achieved.

[0042] It can be understood that this method can be executed by any device, equipment, platform, or device cluster with computing and processing capabilities.

[0043] One or more embodiments of this specification provide a conveying device for heated billets of a heating furnace, as Figures 1 to 7 shown, including a base 1, on which the following are installed:

[0044] An introducing conveyor module 101 for introducing the heated billets into this device;

[0045] An inclined conveying module 201 for inclined conveying of the billets introduced by the introducing conveyor module 101; including an inclined conveyor belt 203 arranged inclinedly, with toothed conveyor rollers 204 respectively and adaptively installed at both ends of the inclined conveyor belt 203. The toothed conveyor rollers 204 are rotatably installed on the mounting seats, and the bottom of the mounting seats is provided with inclined bottom plates 210. The inclined bottom plates 210 are fixedly installed on the base 1 through support feet 211. A resistance control unit is installed on the inclined bottom plates 210 for regulating the resistance that needs to be overcome when the inclined conveyor belt 203 moves. An angular sensor is also installed on the toothed conveyor rollers 204 for monitoring the rotation of the toothed conveyor rollers 204;

[0046] A billet separation module 301 for separating the adhered billets conveyed by the inclined conveying module 201;

[0047] An outgoing conveyor module 401 for conveying the billets separated by the billet separation module 301 and the non-adhered billets to the next process;

[0048] The control module 501 for overall control of the entire device includes a communication unit and a determination unit. The determination unit is used to capture the monitoring data of the angle sensor. If the angle sensor detects an angle change, it is determined that the bar stock on the inclined conveyor belt 203 is in an adhered state. The communication unit sends an instruction to the bar stock separation module 301 to separate the adhered incoming material. If the angle sensor does not detect an angle change, it is determined that the incoming material is in an unadhered state, and the bar stock separation module 301 does not operate.

[0049] During the process of conveying the heated bar stock, the transfer module 101 is introduced to transfer the bar stock in the heating furnace onto the inclined transfer module 201. The inclined conveyor belt 203 does not have a power driving device, and the movement of the inclined conveyor belt 203 is also restricted by the resistance control unit, so that the inclined conveyor belt 203 needs to overcome a certain resistance to move. Then, when the unadhered bar stock enters the inclined conveyor belt 203, the friction between the bar stock and the inclined conveyor belt 203 is rolling friction, and the frictional force is small. At this time, the inclined conveyor belt 203 does not move, and only the bar stock rolls from the inclined conveyor belt 203 onto the lead-out transfer module 401 and is conveyed to the subsequent process. When the adhered bar stock reaches the inclined conveyor belt 203, the bar stocks are adhered to each other and cannot roll along the inclined conveyor belt 203. The frictional force between the adhered bar stock and the inclined conveyor belt 203 is greater than the resistance received by the inclined conveyor belt 203. Then, under the action of the gravity of the adhered bar stock, the inclined conveyor belt 203 is driven to move downward. The angle sensor monitors the rotation of the toothed conveyor roller 204, and the determination unit makes a judgment on the bar stock adhesion disc and sends an instruction to the bar stock separation module 301, causing the bar stock separation module 301 to perform a separation action on the moving adhered bar stock. After the separation is completed, the bar stock enters the lead-out transfer module 401 and is conveyed to the subsequent process. During this process, the device can automatically identify whether the bar stocks are adhered to each other and control whether the bar stock separation module 301 operates according to the adhesion situation, reducing unnecessary separation actions, improving the transportation efficiency, and reducing the energy consumption at the same time.

[0050] In some optional specific embodiments, such as Figures 1 to 7 shown, the control module 501 further includes: an information storage unit for pre-writing the weight and length parameters of different models of bar stocks;

[0051] a model input unit for inputting the model of the currently conveyed bar stock;

[0052] a calculation unit for, according to the model of the currently conveyed bar stock, capturing the weight m of the corresponding bar stock from the information storage unit, and calculating the resistance threshold F_resistance to be output by the resistance control unit according to the weight m of the bar stock, the inclination angle θ of the inclined conveyor belt 203, and the surface friction coefficient μ of the inclined conveyor belt 203, and sending it to the resistance control unit through the communication unit.

[0053] In some optional specific embodiments, such as Figures 1 to 7 shown, the resistance threshold F_resistance to be output by the calculation resistance control unit includes:

[0054] Force analysis:

[0055] When the bar stock is placed on the inclined conveyor belt 203, the bar stock is subjected to the following forces:

[0056] The gravity mg acts vertically downward, where g is the acceleration due to gravity.

[0057] The support force N is perpendicular to the surface of the inclined conveyor belt 203.

[0058] The frictional force F 摩擦 is along the surface of the inclined conveyor belt 203 and in the direction opposite to the trend of motion.

[0059] The resistance F of the inclined conveyor belt 203 阻力 is along the surface of the inclined conveyor belt 203 and in the direction opposite to the trend of motion.

[0060] Decompose the gravity:

[0061] Decompose the gravity mg into a component F 平行 along the conveyor belt direction and a component F 垂直 perpendicular to the inclined conveyor belt 203 direction;

[0062] Frictional force calculation:

[0063] The frictional force F 摩擦 is determined by the support force N and the friction coefficient μ:

[0064] Therefore, F 摩擦 = μmgcosθ;

[0065] The movement condition of the adhered bar stock is:

[0066] When at least two bar stocks are adhered, the total gravity is 2mg. For the adhered bar stock to drive the inclined conveyor belt 203 to move, the following conditions need to be met:

[0067] F 平行 ≤ F 摩擦 ;

[0068] Then: 2mgsinθ ≤ μ2mgcosθ;

[0069] Therefore, between the surface friction coefficient μ of the inclined conveyor belt 203 and the set angle θ of the inclined conveyor belt 203, tanθ ≤ μ needs to be satisfied;

[0070] For the inclined conveyor belt 203 to be driven by the adhered bar stock, then: F 阻力 <2mgsinθ.

[0071] In some alternative specific embodiments, such as Figures 1 to 7 As shown, the inclined conveying module 201 further includes an infrared detection unit for monitoring when the adhered bar stock reaches two different positions on the inclined conveyor belt 203, and sending a signal to the control module 501. The control module 501 includes a timing unit for recording the time when the adhered bar stock reaches two different positions on the inclined conveyor belt 203 and calculating the time difference; the inclined conveying module 201 includes an acceleration calculation unit for calculating the acceleration of the adhered bar stock based on the time difference and sending the acceleration to the control module 501. The control module 501 includes an adhesion quantity calculation unit for calculating the total weight of the adhered bar stock based on the acceleration of the adhered bar stock and calculating the number of adhered bar stocks according to the weight of a single bar stock:

[0072]

[0073] Where: the mass of a single bar stock is m; the resistance of the inclined conveyor belt 203 is F 阻力 ; the inclination angle of the inclined conveyor belt 203 is θ; the distance between two different positions of the bar stock detected by the infrared detection unit is d; the time interval for the adhered bar stock to pass through two different positions is t;

[0074] According to the number of adhered bar stocks, send an instruction to the bar stock separation module 301 to perform the separation action corresponding times.

[0075] In some alternative specific embodiments, such as Figure 5 As shown, the resistance control unit includes a pneumatic ejector rod 209 fixedly installed on the inclined bottom plate 210. The upper end of the pneumatic ejector rod 209 is fixedly connected with a friction plate 208. The friction plate 208 is frictionally connected to the lower surface of the inclined conveyor belt 203 through the pneumatic ejector rod 209. The pneumatic ejector rod 209 is connected with an air pump, and the air pump adjusts the ejection force of the pneumatic ejector rod 209 according to the instruction of the control module 501.

[0076] In some alternative specific embodiments, such as Figures 1 to 2 As shown, the introduction conveying module 101 includes a support column 107 fixedly installed on the base 1. The top end of the support column 107 is fixedly connected with an introduction platform 108. An introduction conveyor belt 102 is fixedly installed on the introduction platform 108. Introduction mounting plates 103 are respectively installed on both sides of the introduction conveyor belt 102. An introduction side plate 104 is fixedly installed on the side surface of the introduction mounting plate 103. An electric telescopic rod 105 is installed on the introduction side plate 104. The end of the electric telescopic rod 105 is fixedly connected with an introduction guide plate 106. The introduction guide plate 106 is arranged along the movement direction of the bar stock to guide the movement of the bar stock and prevent deflection.

[0077] In some optional specific embodiments, the electric telescopic rod 105 is in signal connection with the control unit 501. The control unit 501 controls the distance between the two groups of introducing guide plates 106 according to the length of the corresponding bar material grabbed from the information storage unit, so as to adapt it to the bar material being transported.

[0078] In some optional specific embodiments, as Figures 2 to 4 shown, the infrared detection unit includes a first light sensor 206 and a second light sensor 207. The first light sensor 206 and the second light sensor 207 are respectively installed on the inclined guide plate 205. The inclined guide plate 205 is arranged along the movement direction of the inclined conveyor belt 203, and the inclined guide plate 205 is fixedly connected to the introducing guide plate 106. The first light sensor 206 cooperates with the second light sensor 207 to capture two positions of the adhered bar material on the inclined conveyor belt 203.

[0079] In some optional specific embodiments, as Figure 6 and Figure 7 shown, the outgoing conveying module 401 includes an outgoing conveyor belt 402. Outgoing mounting plates 403 are respectively arranged on both sides of the outgoing conveyor belt 402. An outgoing telescopic rod 404 facing the outgoing conveyor belt 402 is installed on the outgoing mounting plate 403. The end of the outgoing telescopic rod 404 is connected to an outgoing guide plate 405. The outgoing guide plate 405 is arranged along the movement direction of the outgoing conveyor belt 402 to guide the bar material on the outgoing guide plate 405.

[0080] In some optional specific embodiments, as Figure 6 and Figure 7 shown, an inclined support plate 307 and an elastic inclined plane 308 are connected between the outgoing conveyor belt 402 and the inclined conveyor belt 203. The inclined support plate 307 is fixedly installed on the outgoing mounting plate 403. Both ends of the elastic inclined plane 308 are respectively fixedly installed on the inclined support plate 307 and the inclined bottom plate 210. The elastic inclined plane 308 and the inclined support plate 307 together form a transition plate with the same inclination angle as the inclined conveyor belt 203, which is used to smoothly transition the bar material on the inclined conveyor belt 203 to the outgoing conveyor belt 402.

[0081] In some optional specific embodiments, as Figures 6 to 7As shown in the figure, the bar separation module 301 includes a blocking unit and a pressing unit. The blocking unit includes a limit mounting table 406 fixedly installed at the top of the lead-out guide plate 405. Telescopic cylinders 407 are respectively installed on the limit mounting table 406. The output end of the telescopic cylinder 407 is fixedly connected to an electric rotating shaft 408. The electric rotating shaft 408 is power-connected to a baffle 409. The baffle 409 is in a raised state under normal conditions and does not block the non-stuck bar. When the control module 501 detects bar sticking, the baffle 409 rotates above the inclined support plate 307 to block the stuck bar. The pressing unit includes a gantry 302 fixedly installed on the lead-out mounting plate 403. A hydraulic telescopic rod 303 is arranged below the gantry 302. The end of the hydraulic telescopic rod 303 is fixedly connected to a lower pressing plate 304. Elastic telescopic rods 305 and separation pressing rods 306 are respectively installed below the lower pressing plate 304. The elastic telescopic rods 305 are installed above the inclined support plate 307, and the separation pressing rods 306 are installed above the elastic inclined plane 308.

[0082] During use, when the control module 501 determines that the bar on the inclined conveyor belt 203 is in a stuck state, the electric rotating shaft 408 drives the baffle 409 to rotate onto the moving path of the bar, blocking the stuck bar on the inclined support plate 307 and the elastic inclined plane 308. The bar at the forefront is on the inclined support plate 307, and the bar stuck to it is on the elastic inclined plane 308. Through the operation of the pressing unit, the elastic telescopic rod 305 presses down, fixing the forefront bar in the groove formed by the baffle 409 and the inclined support plate 307. The separation pressing rod 306 presses down on the bar stuck to it, deforming the elastic inclined plane 308, thereby separating them. After the pressing action is completed, the baffle 409 rotates upward. Under the action of the slope of the inclined support plate 307, the separated bar rolls onto the lead-out conveyor belt 402. When there are multiple stuck bars, after the separation of the first bar is completed, the baffle 409 rotates from top to bottom, repeating the above actions, and the pressing unit also repeats the above actions until all stuck bars are separated.

[0083] In some optional specific embodiments, such as Figures 2 to 4 As shown in the figure, an inlet plate 202 is connected between the inclined conveyor belt 203 and the introduction conveying module 101. The inlet plate 202 is used to make up for the gap between the introduction conveying module 101 and the inclined conveyor belt 203.

[0084] In some optional specific embodiments, such as Figure 4 As shown in the figure, a plurality of sets of tooth blocks 2041 are arranged in an array on the circumferential side of the toothed conveyor roller 204. Tooth grooves adapted to the plurality of sets of tooth blocks 2041 are provided on the inner side of the inclined conveyor belt 203. Improve the monitoring accuracy of the lifting angle sensor to avoid slipping between the inclined conveyor belt 203 and the toothed conveyor roller 204.

[0085] Working principle of the present invention: During the process of conveying the heated bar stock, the conveying module 101 is introduced to convey the bar stock in the heating furnace onto the inclined conveying module 201. The inclined conveyor belt 203 does not have a power driving device, and the movement of the inclined conveyor belt 203 is also restricted by the resistance control unit, so that the inclined conveyor belt 203 needs to overcome a certain resistance before it can move. Then, when the unadhered bar stock enters the inclined conveyor belt 203, the friction between the bar stock and the inclined conveyor belt 203 is rolling friction, and the friction force is small. At this time, the inclined conveyor belt 203 does not move, and only the bar stock rolls off the inclined conveyor belt 203 onto the lead-out conveying module 401 and is conveyed to the subsequent process. When the adhered bar stock reaches the inclined conveyor belt 203, the adhesion between the bar stocks makes it impossible for them to roll along the inclined conveyor belt 203. The friction force between the adhered bar stock and the inclined conveyor belt 203 is greater than the resistance received by the inclined conveyor belt 203. Then, under the action of the gravity of the adhered bar stock, the inclined conveyor belt 203 is driven to move downward. The angular sensor monitors the rotation of the toothed conveyor roller 204, and the determination unit makes a judgment that the bar stock is adhered to the tray and sends an instruction to the bar stock separation module 301, causing the bar stock separation module 301 to perform a separation action on the moving adhered bar stock. After the separation is completed, the bar stock enters the lead-out conveying module 401 and is conveyed to the subsequent process. During this process, the device can automatically identify whether the bar stocks are adhered to each other and control whether the bar stock separation module 301 operates according to the adhesion situation, reducing unnecessary separation actions, improving the transportation efficiency, and reducing the energy consumption at the same time.
