Description

Technical Field

[0001] The present invention relates to the field of air spring production equipment, and more particularly, to a cord cutting system and a method for using the cord cutting system. Background Art

[0002] The air spring fiber cord cutting production line system is a key equipment for the production of the fiber cord carcass of air springs. In the air spring manufacturing process, the fiber cord carcass is one of the main components. The production of the air spring fiber carcass is to cut the rubber-coated calendered cord at the angles and widths required by the process, and then joint the bevel edges and wind it up for shaping and use.

[0003] According to the process requirements of air springs, the fiber cord used is thinner than that used in traditional tires, usually between 0.5 mm and 1.0 mm. The cord is thin, and it is extremely easy to stretch and deform during passive transportation. The cord feeding platform cannot meet the accuracy requirements of the cord after transportation and cutting, and problems such as cord wrinkling and large cutting angle deviation are likely to occur, and the joint quality cannot be guaranteed.

[0004] At present, with the rapid growth of the market demand for air springs, the requirements for the quality and efficiency of the production of the fiber cord carcass of air springs are getting higher and higher. The traditional carcass cord is mainly manually completed, with poor joint quality, low efficiency, and high labor intensity. In addition, in recent years, in the tire industry, there has also been a form of automatically sucking joints by a manipulator. Its system mainly consists of a pay-off device, a fabric storage and trimming device, a constant-length conveying device, a cutting device, a sucking device, a feeding conveyor belt, a manipulator joint device, a discharging conveyor belt, a winding device, and a control system. The pay-off is fixed, and the cutting knife rotates according to different required cutting angles. During jointing, the cord is sucked by the manipulator, dragged, and rotated and pressed to form a joint. However, it is often restricted by factors such as the softness and easy deformation of the cord itself, resulting in poor joint accuracy of the cord. Moreover, the cord will still be stretched and deformed during the sucking and dragging process, and the joint positioning requires a vision camera, which has a high cost and low accuracy, and it will be more difficult to achieve for large long bevel edges, with low efficiency.

[0005] Therefore, there is a problem of poor performance in the use of the air spring fiber cord cutting production system in the prior art. Summary of the Invention

[0031] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0032] It should be pointed out that unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0033] In the present invention, unless otherwise stated, the orientation words such as "upper, lower, top, bottom" are usually in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction of the component itself; similarly, for the convenience of understanding and description, "inner, outer" refers to the inner and outer of the contour of each component itself, but the above orientation words do not limit the present invention.

[0034] In order to solve the problem of poor performance of the air spring fiber cord fabric cutting production system in the prior art, the present application provides a cord fabric cutting system and a method for using the cord fabric cutting system.

[0035] Such as Figure 6 And Figure 7As shown in the figure, the cord fabric cutting system in the present application includes an unwinding device 90, a cutting device 100, a cord fabric conveying device 200, and an automatic joint device 300. The cutting device 100 is arranged downstream of the unwinding device 90, and one end of the unwinding device 90 close to the cutting device 100 can rotate around the cutting device 100; the cord fabric conveying device 200 is arranged at one end of the unwinding device 90 close to the cutting device 100. The unwinding device 90 conveys the cord fabric to the cutting device 100 through the cord fabric conveying device 200, and at least a part of the cord fabric conveying device 200 can rotate with the unwinding device 90; the automatic joint device 300 is arranged downstream of the cutting device 100, and at least a part of the automatic joint device 300 can rotate relative to the cutting device 100.

[0036] When using the cord fabric cutting system in the present application, since the unwinding device 90 can drive the cord fabric conveying device 200 to rotate relative to the cutting device 100 together, the adjustment of the cord fabric cutting angle can be realized. At the same time, since the cord fabric cutting system in the present application has the cord fabric conveying device 200, the active conveying of the cord fabric can be realized through the cord fabric conveying device 200. Therefore, by using the cord fabric conveying device 200 in the present application, the problems in the prior art that the passive conveying of the cord fabric is extremely easy to stretch and deform, the fiber cord fabric feeding platform cannot meet the requirements of the fiber cord fabric conveying and the precision of the cut product, and phenomena such as cord fabric wrinkling and incorrect cutting angle are likely to occur, and the cutting quality cannot be guaranteed can be effectively solved. Therefore, the cord fabric cutting system in the present application effectively solves the problem of poor performance of the air spring fiber cord fabric cutting production system in the prior art.

[0037] And when using the cord fabric cutting system in the present application, the unwinding device 90 can rotate around the cutting rotation center of the cutting device 100 according to the cutting angle, and unwind the calendered cord fabric to be cut and wind it on the reel for taking up the backing cloth.

[0038] Optionally, the cutting device 100 in the present application can be a disc knife structure in the prior art.

[0039] Specifically, the cord fabric cutting system further includes a clamp pulling device 400. The clamp pulling device 400 is arranged at one end of the cutting device 100 away from the unwinding device 90. The clamp pulling device 400 has a double-axis pulling clamp to realize the pulling of cord fabrics with different angles and widths, and the clamp pulling device 400 is located above the cutting device 100.

[0040] Specifically, the cord fabric cutting system further includes a strip-shaped telescopic belt feeding device 500. The strip-shaped telescopic belt feeding device 500 is arranged at one end of the cutting device 100 away from the pay-off device 90 and is connected to the automatic joint device 300 to supply the cord fabric to be jointed to the automatic joint device 300. And the strip-shaped telescopic belt feeding device 500 is located downstream of the clamp pulling device 400. In this application, the strip-shaped telescopic belt feeding device 500 can be telescoped according to different cutting angles of the cord fabric, so that the hypotenuse of the cord fabric head can approach the joint position at the minimum distance. The strip-shaped telescopic belt is connected to the rotating beam of the automatic joint device 300 through a guide rail slider. The strip-shaped telescopic belt synchronously telescopes with the rotation of the rotating beam of the automatic joint device 300. At the same time, the automatic joint device 300 in this application can rotate according to different required cutting angles to achieve automatic jointing.

[0041] Specifically, the strip-shaped telescopic belt feeding device 500 includes a plurality of strip-shaped telescopic belts, and the plurality of strip-shaped telescopic belts are parallel to each other. Optionally, at least a part of the strip-shaped telescopic belt feeding device 500 can be arranged inside the cutting device 100.

[0042] Specifically, the cord fabric cutting system further includes a discharging device, and the discharging device is arranged at one end of the automatic joint device 300 away from the cutting device 100.

[0043] Specifically, the discharging device includes a discharging conveyor belt 600 and a maintenance conveyor belt 700. The discharging conveyor belt 600 is arranged downstream of the automatic joint device 300, and the maintenance conveyor belt 700 is arranged downstream of the discharging conveyor belt 600. The discharging conveyor belt 600 conveys the cord fabric with the joint completed out of the position of the automatic joint device 300. The discharging conveyor belt 600 is composed of a plurality of strip-shaped telescopic belts and can be telescoped according to different cutting angles of the cord fabric, so that the hypotenuse of the cord fabric tail can approach the joint position at the minimum distance. The strip-shaped telescopic belt synchronously telescopes with the rotation of the rotating beam of the automatic joint device 300. And by arranging the maintenance conveyor belt 700, the process requirements for quality inspection of the cutting and jointing of the cord fabric can be realized.

[0044] Specifically, the cord fabric cutting system further includes a coiling device 800, and the coiling device is arranged downstream of the discharging device.

[0045] In this application, the unrolling device 90 pulls out the undivided cord fabric and backing fabric from the cord fabric roll. The cord fabric is located above the backing fabric. After passing around the first guiding roller of the stripping roller assembly, the cord fabric and the backing fabric are separated. The backing fabric passes downward around the backing fabric stripping roller and then contacts the cord fabric again at the first guiding roller and is conveyed backward together. At this time, the adhesion between the backing fabric and the cord fabric is very small and they can be easily separated. At the second guiding roller, the backing fabric and the cord fabric are separated, and the backing fabric is wound downward onto the backing fabric roll. During the entire unrolling process, the material roll driving motor operates in a reverse torque mode and provides appropriate tension according to the sizes of the material roll and the backing fabric roll to tension the cord fabric and the backing fabric. The backing fabric roll driving motor rotates the backing fabric roll to provide power. The conveying power of the cord fabric is mainly provided by the friction force between the cord fabric and the backing fabric at the second guiding roller. Thus, the cord fabric is conveyed passively to complete the unrolling of the cord fabric and the backing fabric. The backing fabric roll assembly is connected to the trolley frame through a linear guide rail. The backing fabric deviation rectifying mechanism is detected by the backing fabric deviation rectifying detection assembly for the edge of the backing fabric. When the backing fabric runs off track, the electric cylinder pushes the backing fabric roll assembly to translate in the conveying direction to ensure that the center of the backing fabric is always consistent when the backing fabric is curled, avoiding pulling the cord fabric due to the deviation of the backing fabric. After the cord fabric is unrolled, it is continuously conveyed backward through the stretching roller, and the stretching roller can ensure that the cord fabric is flat without wrinkling. The cord fabric can release the tensile deformation generated by unrolling through the first floating roller assembly. The rollers on the first floating roller assembly can freely translate up and down, and the force of the rollers downward is controlled by increasing or decreasing the counterweight, thereby controlling the tension of the cord fabric passing around the first floating roller assembly. The rough deviation rectifying mechanism detects the edge of the cord fabric behind the first floating roller assembly through an optoelectronic device. When a certain distance deviation occurs, the rough deviation rectifying actuator pushes the entire trolley frame to move to complete the rough deviation rectifying of the cord fabric. The pulling-out roller assembly mainly conveys the cord fabric from the first floating roller assembly to the second floating roller assembly, and the edge trimming of the cord fabric can be completed during this period. The functions of the second floating roller assembly and the first floating roller assembly are the same, releasing the tensile deformation of the cord fabric and controlling the tension of the cord fabric during conveying. Under the detection of the wide-width electric eye, the fine deviation rectifying assembly deflects the roller by the electric cylinder according to the deviation direction of the cord fabric to perform deviation rectifying to ensure that the center of the cord fabric is always consistent when the cord fabric is conveyed to subsequent equipment.

[0046] It should be noted that the cord fabric cutting system in this application can realize the automatic production of the air spring fiber cord fabric. Cutting width: 200 - 1000 mm, angle: 45 degrees - 90 degrees, automatic joint width: 200 - 1000 mm. During jointing, the bevel edge of the cord fabric can be directly and actively conveyed to the joint position by the telescopic conveyor belt to solve problems such as stretching, deviation, and wrinkling that occur during the unrolling process of the fiber cord fabric used for air springs at present, as well as problems such as unreliable manual jointing, low efficiency, and high labor intensity, and achieve a fully automatic solution.

[0047] In a specific embodiment of the present application, the cord fabric conveying device 200 includes: a rotating frame assembly having a rotating end and a connecting end, the rotating end having a rotation center, the rotating end being connected to the cutting device 100 through the rotation center, the rotating frame assembly being capable of rotating around the rotation center, and the pay-off device 90 being connected to the connecting end and driving the rotating frame assembly to rotate; a strip belt telescopic assembly, one end of the strip belt telescopic assembly being connected to the cutting device 100 and capable of rotating around the cutting device 100, the other end of the strip belt telescopic assembly being arranged on the rotating frame and capable of moving relative to the rotating frame assembly, and when the rotating frame assembly rotates around the rotation center, the strip belt telescopic assembly can move together with the rotating frame assembly; a conveyor belt assembly, at least a part of the conveyor belt assembly being wound around the rotating frame assembly, and at least another part of the conveyor belt assembly being wound around the strip belt telescopic assembly; a driving assembly, the driving assembly being arranged on the rotating frame assembly and drivingly connected to the conveyor belt assembly. It should be noted that the rotation center in this embodiment coincides with the cutting rotation center of the cutting device 100.

[0048] The method for using the cord fabric cutting system in the present application is to use the above cord fabric cutting system to cut and splice the cord fabric. The method for using the cord fabric cutting system includes: setting the cutting angle, the pay-off device 90 driving the cord fabric conveying device 200 to rotate to the cutting angle and conveying the cord fabric to the cutting device 100 through the cord fabric conveying device 200; the cutting device 100 cutting the cord fabric; and splicing the cut cord fabric through the automatic splicing device 300.

[0049] In a specific embodiment of the present application, the cutting angle is set to α degrees. The α angle is usually 40° to 90 degrees, also known as small-angle cutting. The pay-off device 90 is driven by a pay-off angle rotation driving device to rotate along the cutting rotation center axis, and is guided at the required cutting angle α with respect to the cutting device 100, so that the calendered cord fabric is guided at the cutting angle α with respect to the cutting line through the pay-off device 90. The cord fabric conveying device 200 centrally conveys the guided cord fabric to the position of the cutting device 100. The clamp pulling device 400 pulls the material along the α angle direction, and the clamp pulling device 400 is driven by a double-axis servo to realize pulling the material at the cutting angle α. The cutting device 100 cuts the cord fabric at the required cutting angle α.

[0050] When making joints, the strip telescopic belt feeding device 500 and the discharging conveyor belt 600 are both composed of multiple strip telescopic belts. The strip telescopic belts synchronously expand and contract with the rotation of the rotating beam of the automatic joint device 300. The strip telescopic belt feeding device 500 conveys the cord fabric cut at an angle of α to the joint position of the automatic joint device 300. The automatic joint device 300 is driven by a joint angle rotation driving device and rotates along the joint rotation center axis, so that the automatic joint device 300 forms an angle of α with the cutting line. The strip telescopic belt feeding device 500 is composed of multiple strip telescopic belts. The strip telescopic belts synchronously expand and contract with the rotation of the rotating beam. The strip telescopic belt feeding device 500 can expand and contract according to the cutting cord fabric angle α, so that the hypotenuse of the cord fabric head can approach the joint position at the minimum distance within the range of the angle α. Similarly, the strip telescopic belt discharging device conveys the cord fabric with a joint angle of α out of the joint position of the automatic joint device 300 and makes the tail of the material retreat and accurately stop at the joint line position of the automatic joint device 300. The discharging conveyor belt 600 is composed of multiple strip telescopic belts. The strip telescopic belts synchronously expand and contract with the rotation of the joint rotation center axis. The discharging conveyor belt 600 can expand and contract according to the cutting cord fabric angle α, so that the hypotenuse of the cord fabric tail can approach the joint position at the minimum distance within the range of the angle α. The head and tail of the cord fabric with an angle of α are overlapped through the automatic joint device 300.

[0051] In a specific embodiment of the present application, as Figures 1 to 5 shown, the cord fabric conveying device 200 in the present application includes a rotating frame body assembly 10, a strip belt telescopic assembly 20, a conveyor belt assembly 30, and a driving assembly 40. The rotating frame body assembly 10 has a rotating end 11 and a connecting end 12. The rotating end 11 has a rotation center 111. The rotating end 11 is connected to the cutting device 100 through the rotation center 111, and the rotating frame body assembly 10 can rotate around the rotation center 111; one end of the strip belt telescopic assembly 20 is connected to the cutting device 100 and can rotate around the cutting device 100. The other end of the strip belt telescopic assembly 20 is arranged on the rotating frame body and can move relative to the rotating frame body assembly 10. When the rotating frame body assembly 10 rotates around the rotation center 111, the strip belt telescopic assembly 20 can move together with the rotating frame body assembly 10; at least a part of the conveyor belt assembly 30 is wound around the rotating frame body assembly 10, and at least another part of the conveyor belt assembly 30 is wound around the strip belt telescopic assembly 20; the driving assembly 40 is arranged on the rotating frame body assembly 10 and is drivingly connected to the conveyor belt assembly 30.

[0052] When using the cord fabric conveying device 200 in this application, since the rotating frame assembly 10 and the strip telescopic assembly 20 can rotate around the cutting device 100 by rotating around the rotation center 111, the cutting angle of the cord fabric can be adjusted by the rotation of the rotating frame assembly 10 and the strip telescopic assembly 20. At the same time, since the cord fabric conveying device 200 in this application also has a conveyor belt assembly 30 and a driving assembly 40, the conveyor belt assembly 30 can be driven by the driving assembly 40, thereby realizing the active conveying of the cord fabric. Therefore, by using the cord fabric conveying device 200 in this application, the problems in the prior art that the passive conveying of the cord fabric is extremely easy to stretch and deform, the fiber cord fabric feeding platform cannot meet the requirements of the fiber cord fabric conveying and the precision of the cut product, and phenomena such as cord fabric wrinkling and incorrect cutting angle are likely to occur, and the cutting quality cannot be guaranteed can be effectively solved. Therefore, the cord fabric conveying device 200 in this application solves the problem of poor performance of the cord fabric feeding platform in the prior art.

[0053] It should also be noted that the connection end 12 of the unwinding device 90 in this application is connected to the rotating frame assembly 10 and drives the rotating frame assembly 10 to rotate. That is to say, the two ends of the cord fabric conveying device 200 in this application are respectively connected to the unwinding device 90 and the cutting device 100.

[0054] Optionally, the connection end 12 of the rotating frame assembly 10 in this application also has a mounting plate 80, and the rotating frame assembly 10 can be connected to the unwinding device 90 through the mounting plate, so as to ensure that the unwinding device 90 drives the rotating frame assembly 10 to rotate.

[0055] In a specific embodiment of the present application, the rotating frame assembly 10 includes a frame body 13 and support rollers 14. The rotating end 11 and the connecting end 12 are respectively located at both ends of the frame body 13 in the length direction. The frame body 13 has a plurality of guide rails 131 extending along the length direction. The strip-shaped belt telescopic assembly 20 is movably arranged on the guide rails 131 and can move along the guide rails 131. There are a plurality of support rollers 14, and the plurality of support rollers 14 are arranged at one end of the frame body 13 close to the rotating end 11. The movement path of the conveyor belt assembly 30 sequentially passes through the drive assembly 40, the strip-shaped belt telescopic assembly 20, and the support rollers 14, and after the conveyor belt assembly 30 passes through the support rollers 14, it returns to the drive assembly 40 again. Moreover, the strip-shaped belt telescopic assembly 20 includes a plurality of mounting brackets 21, the conveyor belt assembly 30 includes a plurality of conveyor belt bodies 31, the number of the mounting brackets 21, the conveyor belt bodies 31, the support rollers 14, and the guide rails 131 is the same and they correspond one by one, and the mounting brackets 21 can move along the guide rails 131. And in this embodiment, the frame body 13 may include an upper and a lower layer structure, and the guide rails 131 and the support rollers 14 are arranged on the lower layer structure. At the same time, the conveyor belt body 31 can bypass the upper layer structure and the lower layer structure once. It should also be noted that the length of the upper layer structure can be shorter than the length of the lower layer structure to provide a movement space for the mounting brackets 21 of the strip-shaped belt telescopic assembly 20.

[0056] Specifically, the strip-shaped belt telescopic assembly 20 further includes a rotating shaft 22 and a connecting plate 23. There are a plurality of rotating shafts 22, and the rotating shafts 22 are arranged on the cutting device 100. There are a plurality of connecting plates 23, the number of the rotating shafts 22, the connecting plates 23, and the mounting brackets 21 is the same and they correspond one by one. Both ends of the connecting plate 23 are respectively connected to the corresponding rotating shaft 22 and the mounting bracket 21, and the connecting plate 23 can rotate around the rotating shaft 22. Therefore, when the connecting plate 23 rotates around the rotating shaft 22, the mounting bracket 21 can move along the guide rail 131.

[0057] In a specific embodiment of the present application, the rotation center 111 is located on the center line of the rotating end 11, or in other words, the rotation center 111 is located on the center line of the width direction of the frame body 13. At the same time, the cutting device 100 is provided with a mounting track 70 extending along the width direction of the frame body 13 corresponding to the plurality of rotating shafts 22, and the rotating shafts 22 are arranged on the mounting track.

[0058] Optionally, the cord conveyor device 200 further includes a guiding slide rail 50. The guiding slide rail 50 is arc-shaped. The rotating frame assembly 10 has a pulley 60 cooperating with the guiding slide rail 50. When the rotating frame assembly 10 rotates around the rotation center 111, the rotating frame assembly 10 moves along the guiding slide rail 50 through the pulley 60. By such a setting, it can be effectively ensured that the rotating frame assembly 10 can rotate more easily driven by the unwinding device 90.

[0059] Specifically, the mounting frame 21 includes a horizontal section 211 and a vertical section 212 that are sequentially connected. The vertical section 212 is connected to one end of the horizontal section 211 close to the connection end 12. The length direction of the horizontal section 211 is the same as the length direction of the guide rail 131. One end of the vertical section 212 away from the horizontal section 211 is arranged on the guide rail 131 and moves along the guide rail 131. In the conveying direction of the conveyor belt body 31, the conveyor belt body 31 sequentially passes through one end of the horizontal section 211 close to the vertical section 212, one end of the horizontal section 211 away from the vertical section 212, one end of the vertical section 212 close to the horizontal section 211, one end of the vertical section 212 away from the horizontal section 211, and the support roller 14.

[0060] Preferably, the strip telescopic assembly 20 further includes a plurality of guide rollers 24. At least one guide roller 24 is respectively arranged at least at one end of the horizontal section 211 away from the vertical section 212, one end of the vertical section 212 away from the horizontal section 211, and the connection part between the horizontal section 211 and the vertical section 212 of each mounting frame 21. By arranging the guide rollers 24, the movement of the conveyor belt body 31 can be effectively limited, thereby effectively ensuring the use effect of the curtain fabric conveying device 200.

[0061] It should be noted that when the rotating frame assembly 10 and the strip telescopic assembly 20 rotate relative to the cutting assembly, the movement directions of at least a part of the plurality of mounting frames 21 and the movement directions of at least another part of the plurality of mounting frames 21 are opposite. And by making the mounting frame 21 move along the corresponding guide rail 131, it can be ensured that when the length of the conveyor belt body 31 between one end of the horizontal section 211 away from the vertical section 212 and the driving assembly 40 becomes shorter, the length of the conveyor belt body 31 between one end of the vertical section 212 away from the horizontal section 211 and the support roller 14 becomes longer, and when the length of the conveyor belt body 31 between one end of the horizontal section 211 away from the vertical section 212 and the driving assembly 40 becomes longer, the length of the conveyor belt body 31 between one end of the vertical section 212 away from the horizontal section 211 and the support roller 14 becomes shorter. In this application, the adjustment method of the strip telescopic belt of the strip telescopic belt feeding device 500 and the adjustment method of the discharge conveyor belt 600 can be the same as the adjustment method of the conveyor belt body described above. Of course, the strip telescopic belt of the strip telescopic belt feeding device 500 and the discharge conveyor belt 600 in this application can also be adjusted by other methods.

[0062] Optionally, the driving assembly 40 is arranged at one end of the rotating frame assembly 10 away from the strip telescopic assembly 20. The driving assembly 40 includes a roller mounting frame 41, a driving motor 42, a driving roller 43, a tensioning structure 44, and a driven roller 45. The roller mounting frame 41 is arranged on the rotating frame assembly 10; the driving motor 42, the driving roller 43, the tensioning structure 44, and the driven roller 45 are all arranged on the roller mounting frame 21, and the tensioning structure 44 is located between the driving roller 43 and the driven roller 45.

[0063] When using the cord fabric conveying device 200 in the present application for feeding, the driving motor 42 drives the driving roller 43 to rotate, and the conveyor belt body 31 wound around the driving roller 43 moves to drive the cord fabric to be conveyed to the cutting device 100 for cutting; when the process angle needs to be switched, the driving motor 42 is powered off, the driving roller 43 stops rotating, and the rotating frame assembly 10 rotates around the rotation center 111 on the guiding slide rail 50 along with the unwinding device 90 when the unwinding device 90 rotates. Since the rotation center fixed on the cutting device 100 is arranged on the installation track, when the rotating frame assembly 10 rotates, the conveyor belt body 31 drives the strip telescopic assembly 20 to move in a straight line direction on the guide rail 131 to realize the change of the cutting angle.
