Description

Technical Field

[0001] This utility model relates to the field of coil processing, and more specifically, to a coil correction system. Background Technology

[0002] Rolled materials refer to long, continuous materials such as paper, film, metal foil, rubber, and nonwoven fabric. Whether during unwinding, intermediate stages, or rewinding in roll processing, the moving roll will inevitably experience some lateral displacement (deviation), ultimately leading to machine downtime, uneven rewinding, and the generation of scrap. In the field of roll processing, the deviation problem during roll conveying has long been a technical pain point. Roll deviation leads to a higher scrap rate. The deviation machine can automatically detect and correct the lateral position deviation of the roll during the conveying process in real time, ensuring that the roll always runs along the preset path.

[0003] In the existing roll material processing production line, the offset detection stage often uses an independent offset sensing unit in front of the offset correction machine. Since there is still a distance between the detection and the offset correction, the roll may further deviate, resulting in the offset correction accuracy not being very high. In production lines with higher accuracy requirements, this will be insufficient. Utility Model Content

[0004] The purpose of this invention is to overcome the problem of insufficient offset detection accuracy in existing technology in coil processing production lines, and to provide a coil correction system that can improve detection accuracy, thereby improving correction accuracy.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A web correction system is provided, comprising a feeder and a correction machine. The feeder includes a frame, a plurality of guide rollers rotatably connected to the frame, and a plurality of first sensing devices disposed on the frame. The correction machine includes a base and a second sensing device, a drive device, and a deflection base respectively disposed on the base. The deflection base is rotatably connected to the plurality of correction rollers and is rotatably connected to the base. The drive device is used to drive the deflection base to rotate in a horizontal plane. The first sensing devices are located upstream of the correction rollers in the feeding direction and downstream of the correction rollers in the feeding direction. The first sensing devices are used to detect the deviation of the web strip before correction, and the second sensing devices are used to detect the deviation of the web strip after correction. When the correction rollers are in the initial position, all correction rollers are parallel to the guide rollers.

[0007] This utility model discloses a roll material correction system. In a roll material processing production line, a feeder is set at the source of the production line, with its frame supported on the ground. During the feeding process, the operator pulls the material belt through the guide rollers of the feeder in sequence, and then into the correction machine. The base of the correction machine is supported on the ground. After the production line starts, the material belt will be fed forward under the traction of the main machine. A second sensing device located on the frame is set upstream of the correction roller to monitor the deviation of the material belt before correction. A second sensing device is set downstream of the correction roller to detect the deviation of the material belt after correction and feed it back to the control system. If there is still a large deviation, the control system will control the correction roller to correct the angle, ensuring that the lateral position of the roll material is stable within a high-precision range before entering the subsequent expensive main machine.

[0008] Before the correction machine is started, the correction roller is in the initial position, and the axis of the correction roller is parallel to the axis of the guide roller. After the correction machine is started, the control system will detect the offset information and drive the drive component to rotate the deflection base. This will cause the correction roller to swing in the horizontal plane under the drive component, so that the axis of the correction roller forms a certain angle with the axis of the guide roller. The correction roller will generate a lateral corrective force on the material belt, so that the material belt returns to the original feeding path.

[0009] The roll correction system has a second sensing device downstream of the correction roller to detect the offset of the corrected strip and feed it back to the control system. If there is still a large deviation, the control system will control the correction roller to correct the angle, ensuring that the lateral position of the roll is stable within a high-precision range before entering the expensive subsequent main machine. This is more accurate than the existing technology that only sets a sensing device in front of the correction machine.

[0010] Furthermore, there are two first sensing devices, located on opposite sides of the material strip. The second sensing device is a laser light curtain, which is used to perform a full-width scan of the material strip. The laser light curtain performs a full-width scan of the material strip after the alignment process, resulting in higher precision and ensuring that the horizontal position of the material strip leaving the alignment machine remains stable within a high-precision range.

[0011] Furthermore, the first sensing device includes a first connecting arm disposed on the frame, a first driving member connected to the first connecting arm, a second connecting arm connected to the output end of the first driving member, a second driving member connected to the second connecting arm, a third connecting arm connected to the output end of the second driving member, a third driving member connected to the third connecting arm, and a photoelectric sensor disposed on the output end of the third driving member. The rotation axis of the second connecting arm, the rotation axis of the third connecting arm, and the rotation axis of the photoelectric sensor are parallel to each other and all perpendicular to the axis of the guide roller.

[0012] Driven by the first, second, and third driving components, the photoelectric sensor can move more flexibly and avoid interference. By changing the distance between two photoelectric sensors, it can adapt to material strips of different widths, thus improving adaptability.

[0013] Furthermore, a camera is also provided at the output end of the third connecting arm. The camera can monitor surface defects of the conveyor belt and identify holes.

[0014] Furthermore, the base has two support frames on its top, and each support frame has an arc-shaped guide rail on its top. The two arc-shaped guide rails are symmetrical to each other, and their centers of curvature coincide. The deflection base is rotatably connected to the two arc-shaped guide rails. The arc-shaped guide rails support the deflection base while also being rotatably connected to it, resulting in better stability.

[0015] Furthermore, the bottom surface of the deflection base is provided with four roller seats, each roller seat having four rollers rotatably connected to it. The rotation axis of the rollers is vertical. Two rollers of each roller seat are rolledly connected to one side of the arc-shaped guide rail, and the other two rollers are rolledly connected to the other side of the arc-shaped guide rail. This rolling connection between the rollers and the arc-shaped guide rail reduces friction and improves the smoothness of movement.

[0016] Furthermore, the correction roller includes several locking elements, several switching rollers, and two switching discs rotatably connected to the machine base. The two ends of the switching roller in the axial direction are respectively rotatably connected to the two switching discs of the same correction roller. The locking elements are used to lock the switching discs to the machine frame. Different materials and surface treatments of the correction rollers are required for different roll materials such as metal foil and film. By rotating the switching discs and locking the locking elements, switching rollers of different materials can be switched, adapting to the correction of different roll materials and providing better adaptability.

[0017] Furthermore, the switching disk has a plurality of positioning holes evenly distributed along its circumference, and the locking member is threadedly connected to the base and inserted into the positioning holes. By turning the locking member away from the positioning holes, the switching disk is unlocked and can be rotated; when the locking member is turned into the positioning holes, the switching disk can be locked.

[0018] Furthermore, the driving device is a linear drive, and its output end has a connecting hole. A connecting pin is movably connected to the connecting hole and is connected to the deflection base. The drive drives the deflection base to rotate via the connecting pin, converting linear motion into rotational motion, resulting in a simple structure.

[0019] Furthermore, the driving device is an electric actuator.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. The roll material correction system has a second sensing device downstream of the correction roller to detect the offset of the corrected strip and feed it back to the control system. If there is still a large deviation, the control system will control the correction roller to correct the angle, ensuring that the lateral position of the roll material is stable within a high-precision range before entering the expensive subsequent main machine. This is more accurate than the existing technology that only sets a sensing device in front of the correction machine.

[0022] 2. By driving the first, second and third driving components, the photoelectric sensor can move more flexibly and avoid interference. By changing the distance between the two photoelectric sensors, it can adapt to material strips of different widths, thus improving adaptability.

[0023] 3. The use of curved guide rails and rollers reduces friction and improves the smoothness of movement.

[0024] 4. By rotating the switching disc and locking the locking components, it is possible to switch between different materials of the switching roller, which can adapt to the correction of different rolls and has better adaptability. Attached Figure Description

[0036] Example 1

[0037] This embodiment is a first embodiment of a roll material correction system, such as... Figure 1As shown, the system includes a feeder and a guide roller. The feeder includes a frame 100, several guide rollers 200 rotatably connected to the frame 100, and two first sensing devices 300 disposed on the frame 100. The two first sensing devices 300 are respectively located on both sides of the feed belt. Figure 2 As shown, the first sensing device 300 includes a first connecting arm 310 disposed on the frame 100, a first driving member 320 connected to the first connecting arm 310, a second connecting arm 330 connected to the output end of the first driving member 320, a second driving member 340 connected to the second connecting arm 330, a third connecting arm 350 connected to the output end of the second driving member 340, a third driving member 360 connected to the third connecting arm 350, and a photoelectric sensor 370 disposed on the output end of the third driving member 360. The two photoelectric sensors 370 are used to detect both sides of the material belt. The rotation axis of the second connecting arm 330, the rotation axis of the third connecting arm 350, and the rotation axis of the photoelectric sensor 370 are parallel to each other and perpendicular to the axis of the guide roller 200. A camera 380 is also disposed on the output end of the third connecting arm 350. In this embodiment, the first driving member 320, the second driving member 340, and the third driving member 360 are all motors.

[0038] like Figure 3 As shown, the web guiding machine includes a base 500 and a second sensing device 600, a driving device 400, and a deflection base 700 respectively disposed on the base 500. In this embodiment, the second sensing device 600 is a laser light curtain, used to scan the entire width of the material belt. The transmitting tube and receiving tube of the laser light curtain form a sensing port through which the material belt passes. The laser light curtain is existing technology and will not be described in detail here. The deflection base 700 is rotatably connected to two web guiding rollers 800, and the deflection base 700 is rotatably connected to the base 500.

[0039] like Figure 3 As shown, the drive device 400 is a linear drive component. In this embodiment, the drive device 400 is an electric push rod. The output end of the drive device 400 is provided with a connection hole, and a connecting pin 410 is movably connected in the connection hole. The connecting pin 410 is connected to the deflection base 700. The drive device 400 is used to drive the deflection base 700 to rotate in the horizontal plane. The first sensing device 300 is located upstream of the correction roller 800 in the feeding direction, and the second sensing device 600 is located downstream of the correction roller 800 in the feeding direction. When the correction roller 800 is in the initial position, both correction rollers 800 are parallel to the guide roller 200.

[0040] The working principle of this embodiment is as follows:

[0041] A roll material correction system is provided in a roll material processing production line. A feeder is located at the beginning of the production line, with a frame 100 supported on the ground. During the feeding process, the operator pulls the material belt through the guide rollers 200 of the feeder and then into the correction machine. The base 500 of the correction machine is supported on the ground. After the production line starts, the material belt is pulled forward by the main machine. A first sensing device 300 located on the frame 100 is positioned upstream of the correction roller 800 to monitor the deviation of the material belt before correction. A second sensing device 600 is positioned downstream of the correction roller 800 to detect the deviation of the corrected material belt and feed it back to the control system. If a large deviation still exists, the control system will control the correction roller 800 to correct the angle, ensuring that the lateral position of the roll material is stable within a high-precision range before entering the subsequent expensive main machine.

[0042] Before the correction machine is started, the correction roller 800 is in the initial position, and the axis of the correction roller 800 is parallel to the axis of the guide roller 200. When the correction machine is started, the control system will detect the offset information and start the drive component. The drive component will drive the deflection base 700 to rotate through the connecting pin 410, thereby causing the correction roller 800 to swing in the horizontal plane under the drive component. This will cause the axis of the correction roller 800 to form a certain angle with the axis of the guide roller 200. The correction roller 800 will generate a lateral corrective force on the material belt, so that the material belt returns to the original feeding path.

[0043] The beneficial effects of this utility model are as follows:

[0044] The roll web correction system has a second sensing device 600 downstream of the correction roller 800 to detect the offset of the corrected strip and feed it back to the control system. If there is still a large deviation, the control system will control the correction roller 800 to correct the angle, ensuring that the lateral position of the roll is stable within a high-precision range before entering the expensive subsequent main machine. Compared with the existing technology that only sets a sensing device in front of the correction machine, the accuracy is higher. The laser light curtain performs a full-width scan of the corrected strip, which is even more accurate. Driven by the first driving component 320, the second driving component 340 and the third driving component 360, the photoelectric sensor 370 can move more flexibly and avoid interference. By changing the distance between the two photoelectric sensors 370, it can adapt to strips of different widths, which is more adaptable. The camera 380 can monitor the surface defects of the strip and identify holes.

[0045] Example 2

[0046] This embodiment is a second embodiment of a roll material correction system. This embodiment is similar to the first embodiment, except that, as shown in the following... Figure 4As shown, the top of the base 500 is provided with two support frames 510, and the top of the support frame 510 is provided with an arc-shaped guide rail 520. The two arc-shaped guide rails 520 are symmetrical to each other, and the arc centers of the two arc-shaped guide rails 520 coincide. Figure 5 As shown, the bottom surface of the deflection base 700 is provided with four roller seats 710, and each roller seat 710 is rotatably connected to four rollers 720. The rotation axis of the rollers 720 is along the vertical direction. Two rollers 720 of each roller seat 710 are rolledly connected to one side of the arc-shaped guide rail 520, and the other two rollers 720 are rolledly connected to the other side of the arc-shaped guide rail 520.

[0047] The working principle of this embodiment is as follows:

[0048] The curved guide rail 520 supports the deflection base 700 and can rotate to connect with the deflection base 700, resulting in better stability. The roller 720 is connected to the curved guide rail 520 by rolling, which reduces friction and improves the smoothness of movement.

Figure 6 As shown, the correction roller 800 includes two locking members 810, three switching rollers 820, and two switching disks 830 rotatably connected to the base 500. The two ends of the switching roller 820 in the axial direction are respectively rotatably connected to the two switching disks 830 of the same correction roller 800. The switching disk 830 is evenly provided with three positioning holes along the circumference, which correspond to each correction roller 800. The locking member 810 is threaded to the base 500 and inserted into the positioning hole. In this embodiment, the locking member 810 is a bolt.

[0052] The working principle of this embodiment is as follows:

[0053] Different materials and surface treatments of the correction rollers 800 required for different rolls of metal foil, film and other materials are used. By rotating the switching disk 830 and the locking member 810, the switching rollers 820 of different materials can be switched, which can adapt to the correction of different rolls and has better adaptability. By turning the locking member 810 away from the positioning hole, the switching disk 830 is unlocked and can be rotated. When the locking member 810 is turned into the positioning hole, the switching disk 830 can be locked.

[0054] The remaining working principles of this embodiment are the same as those of Embodiment 2.

[0055] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make various variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
