Description

Technical Field

[0001] The utility model relates to a coding device for a sawing machine, more specifically, it relates to a material cutting and coding structure for a sawing machine. Background Art

[0002] After cutting the bar into multiple sections, the current sawing machine will directly collect the cut bars without coding them. Coding can prevent product counterfeiting, understand the specific information of the product, and facilitate product management, such as classification and search. Therefore, more and more equipment will be equipped with coding mechanisms. However, for sawing machine equipment, there is still a common situation where there is no coding mechanism, or the coding process is not conducive to the work of the sawing machine.

[0003] For example: Chinese patent announcement number CN211991212U, announcement date November 24, 2020, the name of the utility model is a sawing machine for convenient material cutting, the application discloses a sawing machine structure, including a first oil cylinder installed at the end of the bed, a first telescopic rod installed at one end of the first oil cylinder, a motor installed on the first telescopic rod, a wheel installed on one side of the motor, and a saw blade installed on the wheel. This solution can realize the cutting of rod materials of different lengths and improve convenience. However, this solution does not have a coding mechanism and cannot realize the marking operation. Utility Model Content

[0004] The utility model overcomes the problem that the existing sawing machine has no coding and marking operation, and provides a sawing machine material unloading coding structure. The scheme can realize the marking processing of the bar material cut on the sawing machine, and the marking process is simple.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a sawing machine unloading and coding structure, including an unloading conveying mechanism, a clamping mechanism is provided on the unloading conveying mechanism, a coding mechanism is provided at the output end of the unloading conveying mechanism, and a sensor is also provided on the unloading conveying mechanism, and the sensor is slidably connected relative to the unloading conveying mechanism. After the unloading conveying mechanism conveys the pipe material or the bar material to the output end, laser coding is performed through the coding mechanism. The unloading conveying mechanism sensor is used to determine the position of the bar material on the unloading conveying mechanism and control the movement of the bar material. The clamping mechanism is used to fix the bar material so that the bar material is fixed when the marking operation is performed, and the marking is effective; the position of the sensor on the unloading conveying mechanism can be changed at will, and by changing the position of the sensor, the marking and unloading of bars of different sizes can be detected. This solution can not only realize the marking of bars, but also simplify the marking process.

[0006] Preferably, the unloading conveying mechanism comprises a V-shaped roller and a driving mechanism arranged on the side of the V-shaped roller and driving the V-shaped roller to transmit. The unloading conveying mechanism is a plurality of V-shaped rollers arranged side by side to form a conveying roller structure. The driving mechanism arranged on the side of the V-shaped roller can drive the V-shaped roller to rotate. Chain transmission is adopted between each V-shaped roller, so that a transmission chain is formed on the side of the unloading conveying mechanism, that is, the side of the V-shaped roller.

[0007] Preferably, the driving mechanism is provided with a protective shell, the upper surface of which is not lower than the height of the V-shaped roller, and the protective shell is provided with a slide groove, in which the sensor is slidably connected. The protective shell is mainly used to cover the transmission chain on the side of the V-shaped roller to prevent the chain from being stuck by debris in the working environment, so as to ensure the normal operation of the unloading conveying mechanism; the height of the upper surface of the protective shell needs to be greater than the height of the V-shaped roller, or be flush with the height of the V-shaped roller, so that after the sensor is set on the protective shell, the sensor can detect the conveyed material on the V-shaped roller, and the slide groove on the protective shell can allow the sensor to change its position. The change in the position of the sensor can detect materials of different lengths, thereby increasing its scope of use and making it more convenient for the material to be coded.

[0008] Preferably, the output end of the material unloading conveying mechanism is provided with a loading area, which is used to load the materials that have completed the coding operation. When the materials are coded, they are transported by the material unloading conveying mechanism and fall into the material area.

[0009] Preferably, the coding mechanism is arranged on the side of the loading area and is located below the output end of the unloading conveying mechanism. The coding mechanism needs to be near the loading area and needs to be arranged on the side of the unloading conveying mechanism and also below the unloading conveying mechanism. When the bar material is coded, it can fall directly into the loading area.

[0010] Preferably, a transmission rail is provided on the side of the unloading conveying mechanism away from the driving mechanism, and the clamping mechanism is slidably connected to the transmission rail. The transmission rail is used to transmit the clamping mechanism, and the clamping of the bar at different positions can be achieved by changing the position of the clamping mechanism, that is, the position of the clamping mechanism is different for bars of different lengths, thereby improving the practicality of the entire sawing machine.

[0011] Preferably, the transmission rail is provided with a rack, and the bottom of the clamping mechanism is provided with a gear adapted to the transmission rail. The transmission rail adopts the meshing transmission of the gear and the rack, and the gear and rack meshing transmission can improve the transmission efficiency of the clamping structure and improve the transmission accuracy.

[0012] Preferably, the number of the sensors is two. The number of sensors is set to two, so that the bar material starts to slow down when it is about to enter the coding mechanism, preventing the bar material from being excessively conveyed.

[0013] Preferably, the number of the sensors is three. The number of sensors is set to three, so that the bar material starts to slow down when it is about to enter the coding mechanism, the deceleration effect is better, the coding position of the bar material is ensured to be consistent, and the bar material is prevented from being excessively conveyed.

[0014] Preferably, a limit stopper is further provided on the transmission rail, which can prevent the clamping mechanism from slipping off the rail and protect the clamping mechanism.

DETAILED DESCRIPTION

[0024] The technical solution of the utility model is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0025] Example 1: Figures 1 to 5 The sawing machine blanking and coding structure shown in the figure comprises a feeding conveying mechanism 12, a cutting device 13 and a blanking conveying mechanism 1. The cutting device 13 is arranged between the feeding conveying mechanism 12 and the blanking conveying mechanism 1. The blanking conveying mechanism 1 is provided with a plurality of V-shaped rollers 5. Adjacent V-shaped rollers 5 are connected by a transmission chain. A driving mechanism 14 is also arranged on the side of the V-shaped roller 5. Thus, the driving mechanism 14 drives one V-shaped roller 5 to rotate, and all V-shaped rollers 5 rotate together, thereby realizing the transportation of the bar by the blanking conveying mechanism 1. A protective shell 6 is arranged on the side of the blanking conveying mechanism 1 and above the transmission chain of the V-shaped roller 5. Since the V-shaped rollers 5 are arranged side by side along the length direction of the blanking conveying mechanism 1, the protective shell 6 is also arranged along the length direction of the blanking conveying mechanism 1. A chute 7 is arranged in the length direction of the protective shell 6. A sensor 4 is arranged on the chute 7. The sensor 4 can slide in the chute 7, so that the position of the sensor 4 relative to the output end of the blanking conveying mechanism 1 is different, so as to control bars of different lengths.

[0026] A loading area 8 is provided at the output end of the unloading conveying mechanism 1. The loading area 8 is located below the output end of the unloading conveying mechanism 1 and in the conveying direction of the unloading conveying mechanism 1. When the center of gravity of the rod is transmitted out of the unloading conveying mechanism 1, the rod will begin to fall into the loading area 8. A coding mechanism 3 is also provided at the output end of the unloading conveying mechanism 1, and the coding mechanism 3 includes a coding machine 3.1 and a coding machine base 3.2. The coding machine base 3.2 is fixed to the sawing machine by anchor bolts, and two pairs of guide grooves 3.3 are provided on the top of the coding machine base 3.2, and two sliders 3.4 matched with the guide grooves 3.3 are provided below the coding machine 3.1, so that the coding machine 3.1 can slide on the guide grooves 3.3; in this embodiment, the coding machine 3.1 adopts a laser focusing coding method. When the rod is in place, the coding machine 3.1 slides on the guide grooves 3.3, so that the coding machine 3.1 extends to the end of the rod and performs coding operation at the end. Since the rod is placed on the V-shaped roller 5, the position of the rod is fixed each time, ensuring that the coding position of the rod is consistent.

[0027] The coding mechanism 3 needs to be arranged at the output end of the unloading conveying mechanism 1 and at the side of the loading area 8. Since the loading area 8 is located in the conveying direction of the unloading conveying mechanism 1, the coding mechanism 3 is located at the side of the unloading conveying mechanism 1 and at the lower position. During the coding process of the bar, the front end of the bar (in this embodiment, the end of the bar that first leaves the unloading conveying mechanism 1 is defined as the front end, and the other end is defined as the rear end) needs to be conveyed to the outside of the unloading conveying mechanism 1. At this time, the coding machine 3.1 can perform coding operations on the bar exposed to the unloading conveying mechanism 1.

[0028] A transmission rail 9 is provided on the other side of the unloading conveying mechanism 1, that is, the side away from the driving mechanism 14 and the transmission chain. There are two transmission rails 9 arranged in parallel. A clamping frame 2 is provided above the two transmission rails 9. A guide groove cooperating with the transmission rail 9 is provided at the bottom of the clamping mechanism 2, so that the clamping mechanism 2 can slide on the transmission rail 9. A gear is provided at the bottom of the clamping mechanism 2, and a spur rack 10 is provided between the two transmission rails 9. The gear and the rack 10 are meshed for transmission, so that the clamping mechanism 2 moves on the transmission rail 9. The meshing transmission of the gear and the rack 10 can improve the transmission efficiency of the clamping mechanism 2 and improve the transmission accuracy.

[0029] The clamping mechanism 2 includes two clamping plates 2.1 for clamping the rod. When the coding machine 3.1 performs coding operation on the rod, it is necessary to ensure that the rod is in the correct position on the unloading conveying mechanism 1 without deflection. The clamping plates 2.1 can clamp the rod in the length direction and perform deviation correction operation at the same time, ensuring that the coding operation of the coding mechanism 3 is carried out normally.

[0030] At the end of the transmission rail 9 and near the output end of the unloading conveying mechanism 1, a limit stopper 11 is further provided. The limit stopper 11 can prevent the clamping mechanism 2 from slipping off the track, thereby protecting the clamping mechanism.

[0031] When it is necessary to code the bar, it is necessary to first determine the length of the bar, and determine the position of the sensor 4 on the unloading and conveying mechanism 1 according to the length of the bar. Specifically, the following conditions are met: when the rear end of the bar corresponds to the position of the sensor 4, the front end of the bar needs to be outside the unloading and conveying mechanism 1, and the distance between the front end of the bar and the output end of the unloading and conveying mechanism 1 is 10 cm, and the front end of the bar just corresponds to the coding mechanism 3, and at this time, the clamping mechanism 2 needs to be moved into place to ensure that the clamping mechanism 2 can still clamp the bar in place at this time.

[0032] The specific process of bar coding is as follows.

[0033] When the bar moves on the feeding conveyor mechanism 1, the front end of the bar first passes through the sensor 4. After the sensor 4 detects the signal, it transmits the command to the control system to control the feeding conveyor mechanism 1 to slow down. When the rear end of the bar moves to the corresponding position of the sensor 4 and passes the position of the sensor 4, the detection signal of the sensor 4 disappears. At this time, the control system controls the feeding conveyor mechanism 1 to stop running, and the clamping mechanism 2 clamps the bar to correct the position of the bar. Then the coding machine 3.1 focuses on coding to complete the coding operation. After the coding operation is completed, the control system continues to control the feeding conveyor mechanism 1 to move until the bar falls into the loading area 8. Repeat the above steps for the next bar.

[0034] Example 2: Figure 1 , Figure 2 as well as Figures 3 to 6 A sawing machine unloading and coding structure is shown, and the sawing machine includes a loading conveying mechanism 12, a cutting device 13 and a unloading conveying mechanism 1. The cutting device 13 is arranged between the loading conveying mechanism 12 and the unloading conveying mechanism 1. A plurality of V-shaped rollers 5 are arranged on the unloading conveying mechanism 1. Adjacent V-shaped rollers 5 are connected by a transmission chain, and a driving mechanism 14 is also arranged on the side of the V-shaped roller 5. The driving mechanism 14 drives a V-shaped roller 5 to rotate, and all the V-shaped rollers 5 will rotate together, thereby realizing the unloading conveying mechanism 1 to transport the bar. A protective shell 6 is provided on the side of the unloading conveying mechanism 1 and above the transmission chain of the V-shaped roller 5. Since the V-shaped rollers 5 are arranged side by side along the length direction of the unloading conveying mechanism 1, the protective shell 6 is also arranged along the length direction of the unloading conveying mechanism 1. A chute 7 is provided in the length direction of the protective shell 6. A sensor 4 is provided on the chute 7. The sensor 4 includes a first sensor 4.1 and a second sensor 4.2. Both the first sensor 4.1 and the second sensor 4.2 can slide in the chute 7, so that the position of the sensor 4 relative to the output end of the unloading conveying mechanism 1 is different, so as to facilitate the control of bars of different lengths. It should be noted that the second sensor 4.2 is close to the output end of the unloading conveying mechanism 1, and the first sensor 4.1 is far away from the output end of the unloading conveying mechanism 1 relative to the second sensor 4.2.

[0035] A loading area 8 is provided at the output end of the unloading conveying mechanism 1. The loading area 8 is located below the output end of the unloading conveying mechanism 1 and in the conveying direction of the unloading conveying mechanism 1. When the center of gravity of the rod is transmitted out of the unloading conveying mechanism 1, the rod will begin to fall into the loading area 8. A coding mechanism 3 is also provided at the output end of the unloading conveying mechanism 1, and the coding mechanism 3 includes a coding machine 3.1 and a coding machine base 3.2. The coding machine base 3.2 is fixed to the sawing machine by anchor bolts, and two pairs of guide grooves 3.3 are provided on the top of the coding machine base 3.2, and two sliders 3.4 matched with the guide grooves 3.3 are provided below the coding machine 3.1, so that the coding machine 3.1 can slide on the guide grooves 3.3; in this embodiment, the coding machine 3.1 adopts a laser focusing coding method. When the rod is in place, the coding machine 3.1 slides on the guide grooves 3.3, so that the coding machine 3.1 extends to the end of the rod and performs coding operation at the end. Since the rod is placed on the V-shaped roller 5, the position of the rod is fixed each time, ensuring that the coding position of the rod is consistent.

[0036] The coding mechanism 3 needs to be arranged at the output end of the unloading conveying mechanism 1 and at the side of the loading area 8. Since the loading area 8 is located in the conveying direction of the unloading conveying mechanism 1, the coding mechanism 3 is located at the side of the unloading conveying mechanism 1 and at the lower position. During the coding process of the bar, the front end of the bar (in this embodiment, the end of the bar that first leaves the unloading conveying mechanism 1 is defined as the front end, and the other end is defined as the rear end) needs to be conveyed to the outside of the unloading conveying mechanism 1. At this time, the coding machine 3.1 can perform coding operations on the bar exposed to the unloading conveying mechanism 1.

[0037] A transmission rail 9 is provided on the other side of the unloading conveying mechanism 1, that is, the side away from the driving mechanism 14 and the transmission chain. There are two transmission rails 9 arranged in parallel. A clamping frame 2 is provided above the two transmission rails 9. A guide groove cooperating with the transmission rail 9 is provided at the bottom of the clamping mechanism 2, so that the clamping mechanism 2 can slide on the transmission rail 9. A gear is provided at the bottom of the clamping mechanism 2, and a spur rack 10 is provided between the two transmission rails 9. The gear and the rack 10 are meshed for transmission, so that the clamping mechanism 2 moves on the transmission rail 9. The meshing transmission of the gear and the rack 10 can improve the transmission efficiency of the clamping mechanism 2 and improve the transmission accuracy.

[0038] The clamping mechanism 2 includes two clamping plates 2.1 for clamping the rod. When the coding machine 3.1 performs coding operation on the rod, it is necessary to ensure that the rod is in the correct position on the unloading conveying mechanism 1 without deflection. The clamping plates 2.1 can clamp the rod in the length direction and perform deviation correction operation at the same time, ensuring that the coding operation of the coding mechanism 3 is carried out normally.

[0039] At the end of the transmission rail 9 and near the output end of the unloading conveying mechanism 1, a limit stopper 11 is further provided. The limit stopper 11 can prevent the clamping mechanism 2 from slipping off the track, thereby protecting the clamping mechanism.

[0040] When it is necessary to code the rod, it is necessary to first determine the length of the rod, and determine the position of the sensor 4 on the unloading and conveying mechanism 1 according to the length of the rod. Specifically, the following conditions are met: when the rear end of the rod corresponds to the position of the first sensor 4.1, the front end of the rod needs to be outside the unloading and conveying mechanism 1, and the distance between the front end of the rod and the output end of the unloading and conveying mechanism 1 is 10 cm, and the end of the front end of the rod just corresponds to the coding mechanism 3, and at this time it is also necessary to move the clamping mechanism 2 into place to ensure that the clamping mechanism 2 can still clamp the rod in place at this time, and the second sensor 4.2 needs to be set at a position 10 cm away from the output end of the unloading and conveying mechanism 1.

[0041] The specific process of bar coding is as follows.

[0042] When the bar moves on the unloading conveying mechanism 1, the front end of the bar first passes through the first sensor 4.1. After the first sensor 4.1 detects a signal, it transmits a command to the control system to control the unloading conveying mechanism 1 to slow down. Further, when the front end of the bar reaches the corresponding position of the second sensor 4.2, the second sensor 4.2 detects a signal and transmits a command to the control system. The control system further reduces the speed of the unloading conveying mechanism 1. When the rear end of the bar moves to the corresponding position of the first sensor 4.1 and the rear end passes the position of the first sensor 4.1, the detection signal of the first sensor 4.1 disappears. At this time, the control system controls the unloading conveying mechanism 1 to stop running, and the clamping mechanism 2 clamps the bar to correct the position of the bar, and then the coding machine 3.1 focuses on coding to complete the coding operation. After the coding operation is completed, the control system continues to control the unloading conveying mechanism 1 to move until the bar falls into the loading area 8. Repeat the above steps for the next bar.

[0043] In this embodiment, an additional sensor is added to reduce the speed of the unloading conveying mechanism 1 in stages to avoid reducing it to a stop state at once, which causes the inertia of the bar to deviate the position of the bar. Therefore, the control accuracy of this solution will be higher.

[0044] Example 3: Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7A sawing machine unloading and coding structure is shown, and the sawing machine includes a loading conveying mechanism 12, a cutting device 13 and a unloading conveying mechanism 1. The cutting device 13 is arranged between the loading conveying mechanism 12 and the unloading conveying mechanism 1. A plurality of V-shaped rollers 5 are arranged on the unloading conveying mechanism 1. Adjacent V-shaped rollers 5 are connected by a transmission chain, and a driving mechanism 14 is also arranged on the side of the V-shaped roller 5. The driving mechanism 14 drives a V-shaped roller 5 to rotate, and all the V-shaped rollers 5 will rotate together, thereby realizing the unloading conveying mechanism 1 to transport the bar. A protective shell 6 is provided on the side of the unloading conveying mechanism 1 and above the transmission chain of the V-shaped roller 5. Since the V-shaped rollers 5 are arranged side by side along the length direction of the unloading conveying mechanism 1, the protective shell 6 is also arranged along the length direction of the unloading conveying mechanism 1. A chute 7 is provided in the length direction of the protective shell 6. A sensor 4 is provided on the chute 7. The sensor 4 includes a first sensor 4.1, a second sensor 4.2 and a third sensor 4.3. The first sensor 4.1, the second sensor 4.2 and the third sensor 4.3 can all slide in the chute 7, so that the position of the sensor 4 relative to the output end of the unloading conveying mechanism 1 is different, so as to facilitate the control of bars of different lengths. It should be noted that the second sensor 4.2 is close to the output end of the unloading conveying mechanism 1, and the first sensor 4.1 is far away from the output end of the unloading conveying mechanism 1 relative to the second sensor 4.2, and the third sensor 4.3 is located between the first sensor 4.1 and the second sensor 4.2.

[0045] A loading area 8 is provided at the output end of the unloading conveying mechanism 1. The loading area 8 is located below the output end of the unloading conveying mechanism 1 and in the conveying direction of the unloading conveying mechanism 1. When the center of gravity of the rod is transmitted out of the unloading conveying mechanism 1, the rod will begin to fall into the loading area 8. A coding mechanism 3 is also provided at the output end of the unloading conveying mechanism 1, and the coding mechanism 3 includes a coding machine 3.1 and a coding machine base 3.2. The coding machine base 3.2 is fixed to the sawing machine by anchor bolts, and two pairs of guide grooves 3.3 are provided on the top of the coding machine base 3.2, and two sliders 3.4 matched with the guide grooves 3.3 are provided below the coding machine 3.1, so that the coding machine 3.1 can slide on the guide grooves 3.3; in this embodiment, the coding machine 3.1 adopts a laser focusing coding method. When the rod is in place, the coding machine 3.1 slides on the guide grooves 3.3, so that the coding machine 3.1 extends to the end of the rod and performs coding operation at the end. Since the rod is placed on the V-shaped roller 5, the position of the rod is fixed each time, ensuring that the coding position of the rod is consistent.

[0046] The coding mechanism 3 needs to be arranged at the output end of the unloading conveying mechanism 1 and at the side of the loading area 8. Since the loading area 8 is located in the conveying direction of the unloading conveying mechanism 1, the coding mechanism 3 is located at the side of the unloading conveying mechanism 1 and at the lower position. During the coding process of the bar, the front end of the bar (in this embodiment, the end of the bar that first leaves the unloading conveying mechanism 1 is defined as the front end, and the other end is defined as the rear end) needs to be conveyed to the outside of the unloading conveying mechanism 1. At this time, the coding machine 3.1 can perform coding operations on the bar exposed to the unloading conveying mechanism 1.

[0047] A transmission rail 9 is provided on the other side of the unloading conveying mechanism 1, that is, the side away from the driving mechanism 14 and the transmission chain. There are two transmission rails 9 arranged in parallel. A clamping frame 2 is provided above the two transmission rails 9. A guide groove cooperating with the transmission rail 9 is provided at the bottom of the clamping mechanism 2, so that the clamping mechanism 2 can slide on the transmission rail 9. A gear is provided at the bottom of the clamping mechanism 2, and a spur rack 10 is provided between the two transmission rails 9. The gear and the rack 10 are meshed for transmission, so that the clamping mechanism 2 moves on the transmission rail 9. The meshing transmission of the gear and the rack 10 can improve the transmission efficiency of the clamping mechanism 2 and improve the transmission accuracy.

[0048] The clamping mechanism 2 includes two clamping plates 2.1 for clamping the rod. When the coding machine 3.1 performs coding operation on the rod, it is necessary to ensure that the rod is in the correct position on the unloading conveying mechanism 1 without deflection. The clamping plates 2.1 can clamp the rod in the length direction and perform deviation correction operation at the same time, ensuring that the coding operation of the coding mechanism 3 is carried out normally.

[0049] At the end of the transmission rail 9 and near the output end of the unloading conveying mechanism 1, a limit stopper 11 is further provided. The limit stopper 11 can prevent the clamping mechanism 2 from slipping off the track, thereby protecting the clamping mechanism.

[0050] When it is necessary to code the bar, it is necessary to first determine the length of the bar, and determine the position of the sensor 4 on the unloading and conveying mechanism 1 according to the length of the bar. Specifically, the following conditions are met: when the rear end of the bar corresponds to the position of the first sensor 4.1, the front end of the bar needs to be outside the unloading and conveying mechanism 1, and the front end of the bar is 10 cm away from the output end of the unloading and conveying mechanism 1, and the end of the front end of the bar just corresponds to the coding mechanism 3, and at this time it is also necessary to move the clamping mechanism 2 into place to ensure that the clamping mechanism 2 can still clamp the bar in place at this time, and the second sensor 4.2 needs to be set at a position 10 cm away from the output end of the unloading and conveying mechanism 1, and the third sensor 4.3 is set in a central position between the first sensor 4.1 and the second sensor 4.2.

[0051] The specific process of bar coding is as follows.

[0052] When the bar moves on the unloading conveying mechanism 1, the front end of the bar first passes through the first sensor 4.1. After the first sensor 4.1 detects a signal, it transmits a command to the control system to control the unloading conveying mechanism 1 to slow down; further, when the front end of the bar reaches the corresponding position of the third sensor 4.3, the third sensor 4.3 detects a signal and transmits a command to the control system, and the control system further reduces the speed of the unloading conveying mechanism 1; further, when the front end of the bar reaches the corresponding position of the second sensor 4.2, the second sensor 4.2 detects a signal and transmits a command to the control system, and the control system further reduces the unloading conveying mechanism 1. The speed of the conveying mechanism 1, at this time, the speed of the unloading conveying mechanism 1 is already very slow, and the rear end of the bar is also close to the position of the first sensor 4.1. When the rear end of the bar moves to the corresponding position of the first sensor 4.1, and after the rear end passes the position of the first sensor 4.1, the detection signal of the first sensor 4.1 disappears. At this time, the control system controls the unloading conveying mechanism 1 to stop running, and the clamping mechanism 2 clamps the bar to correct the position of the bar, and then the coding machine 3.1 focuses on coding to complete the coding operation. After the coding operation is completed, the control system continues to control the unloading conveying mechanism 1 to move until the bar falls into the loading area 8. Repeat the above steps for the next bar.

[0053] In this embodiment, three sensors are used to reduce the speed of the unloading and conveying mechanism 1 by secondary stages, so that the unloading and conveying mechanism 1 can achieve the best effect from the moving state to the stopping state, avoiding the inertia of the bar material from affecting the stopping position. Therefore, this solution has the highest control accuracy.
