Description

Technical Field

[0001] The invention belongs to the technical field of metal processing, and relates to a winding machine device, in particular to a non-contact metal strip damage-free automatic winding method and an automatic winding machine. Background Art

[0002] The winder is a mechanical device usually installed at the end of the production line. Its main function is to rewind the cut strip layer by layer in an orderly manner to form a coil. In the prior art, it is difficult to apply appropriate pressure to the strip continuously and stably when winding the strip, which will cause gaps between the wound strips, resulting in poor coil quality. For this reason, people have conducted long-term exploration and proposed various solutions.

[0003] For example, a Chinese patent document discloses a winding machine [application number: 201220512295.7], which includes a driving motor, a transmission, and a pressing arm. The transmission is arranged in the transmission, a flip shaft is arranged on the upper part of the transmission, the flip shaft is connected to the hydraulic cylinder through a guide arm, a roller is arranged at the front end of the pressing arm, and a main shaft is arranged on the output shaft of the transmission. When the present invention is used, the roller is pressed on the surface of the material, and the roll of material becomes larger and pushes the roller up, so that the roller and the roll are kept in a relatively fixed position.

[0004] Although the above scheme has a good effect of continuously and stably tightening the strip, there is friction between the roller and the material due to contact, which easily causes wear of the material and affects the product quality of the final roll. In addition, the separation arrangement of the rollers is simple and the separation method is complicated, which cannot meet the needs of high-intensity production. Summary of the invention

[0005] The object of the present invention is to provide a non-contact metal strip non-damaging automatic winding machine with a simple separation setting method and capable of ensuring the quality of coiled product in view of the above problems.

[0006] Another object of the present invention is to provide a non-contact metal strip damage-free automatic winding method.

[0007] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: the non-contact metal strip damage-free automatic winding machine comprises a frame, a strip winding mechanism is provided on the frame, and the feature is that a strip dividing device can be used to automatically arrange the spacing between dividing plates on one side above the strip winding mechanism, and the frame is also provided with a bracket hinge seat, and the bracket hinge seat is hinged with a strip dividing device bracket through a first hinge axis, and the strip dividing device bracket is located on one side of the strip dividing device bracket and the strip dividing device is provided, and the other side is provided with a swinging drive mechanism that can drive the strip dividing device bracket to rotate around the hinge point so that the hydraulic expansion shaft of the strip dividing device does not contact the strip and can be separated by the dividing plate unit.

[0008] The strip separator device installed on the upper side of the strip winding mechanism has a hydraulic expansion shaft close to the strip, which can ensure the stability of the strip when winding the strip. Since the hydraulic expansion shaft does not contact the strip, it will not wear the surface of the strip, thereby improving the quality of the coil. And because the strip separator device can automatically arrange the spacing of the separators, there is no need for manual work when setting the spacing, making the setting method simple and easy to operate.

The distance between the rotation center of the winding drum and the center of the first articulated shaft is equal to the distance between the center of the first articulated shaft and the center of the hydraulic expansion shaft of the strip separating device.

The PLC control system adjusts the angle θ according to the coil diameter. The PLC control system includes a PLC controller, and the PLC controller is connected to an interactive screen, a rotating liquid supply component and a claw driving mechanism.

And by flexibly adjusting the distance between the strip separator and the strip, it can ensure that the strip is always separated by the separator during the winding process, avoiding adhesion or damage between the strips. At the same time, the hydraulic expansion shaft does not contact the coil, which not only protects the coil but also ensures the separation effect.

And the inner shaft and the outer shaft tube are fixed with shaft necks at both ends, and this design enhances the mechanical stability of the hydraulic expansion shaft.

[0018] In the above-mentioned non-contact metal strip non-damaging automatic winding machine, a plug is provided at the inner end of the shaft neck, the outer wall of the plug is connected to the inner wall of the outer shaft tube, and a plurality of axially distributed sealing rings are provided between the plug and the outer shaft tube, a third liquid passage is axially penetrated on the plug, the first liquid passage is connected to the second liquid passage through the third liquid passage, the plug is connected to the shaft neck as a whole, and the shaft neck is connected to the hydraulic expansion shaft frame through the bearing seat.

DETAILED DESCRIPTION

[0035] like Figures 1 to 11 As shown, the non-contact metal strip damage-free automatic winding machine includes a frame 1, on which a strip winding mechanism 2 is provided, and a strip dividing device 3 on one side above the strip winding mechanism 2 can be used to automatically arrange the spacing between dividing plates. The frame 1 is also provided with a bracket hinge seat 11, and the bracket hinge seat 11 is hinged with a strip dividing device bracket 31 with hinge interfaces at both ends and the middle part through a first hinge shaft 12. The first hinge shaft 12 is arranged in the middle of the strip dividing device bracket 31, and a strip dividing device 3 is provided at one end of the strip dividing device bracket 31, and a swing driving mechanism 4 is provided at the other end, which can drive the strip dividing device bracket 31 to rotate around the hinge point so that the hydraulic expansion shaft 32 of the strip dividing device 3 is close to but not in contact with the strip and can be separated by the dividing plate unit 33.

[0036] In this embodiment, the strip is wound by the strip winding mechanism 2, and a strip dividing device 3 is provided on the upper side, which can automatically set a suitable dividing interval to ensure the stability of the strip during winding. In addition, a swing driving mechanism 4 is provided to keep the strip dividing device 3 in a suitable position at all times, so that the hydraulic expansion shaft 32 is close to the strip but not in contact with it during strip winding, thereby avoiding damage to the surface of the strip and ensuring product quality.

[0037] More specifically, the strip separating device 3 includes a hydraulic expansion shaft frame 34, which is fixedly connected to one end of the strip separating device bracket 31 close to the strip separating device 3, and a hydraulic expansion shaft 32 is provided on the hydraulic expansion shaft frame 34, and a plurality of separating plate units 33 are provided on the hydraulic expansion shaft 32. A pusher claw 351 for moving the separating plate unit 33 axially along the hydraulic expansion shaft 32 is provided on one side of the hydraulic expansion shaft 32, and the pusher claw 351 is connected to a pusher claw driving mechanism 35 capable of driving the pusher claw 351 to move radially and axially along the hydraulic expansion shaft 32.

[0038] More specifically, the swing drive mechanism 4 includes a linear drive cylinder 41, the lower end of the linear drive cylinder 41 is hinged on a cylinder hinge seat 42, the cylinder hinge seat 42 is fixed on one side of the frame 1, and the upper end is hinged on one end of the strip separator bracket 31 close to the swing drive mechanism 4, and the PLC control system 5 is connected to the linear drive cylinder 41 to control the stroke of the linear drive cylinder 41.

[0039] More specifically, the strip winding mechanism 2 includes a winding drum 21, which is connected to a winding drum rotation drive assembly 22. The winding drum 21 is arranged on the winding drum rotation drive assembly 22 and is driven to rotate by the winding drum rotation drive assembly 22. The distance between the rotation center of the winding drum 21 and the center of the first articulated shaft 12 is equal to the distance between the center of the first articulated shaft 12 and the center of the hydraulic expansion shaft 32 of the strip separating device 3. The PLC control system 5 calculates the coil diameter of the coil on the winding drum 21 through the linear speed of the coil and the rotation speed of the winding drum 21 of the strip winding mechanism 2. The linear speed of the coil is measured by a speed sensor or an encoder, and the rotation speed of the winding drum 21 is measured by a rotation speed encoder or a rotation speed sensor installed on the winding drum 21. The swing angle of the strip separating device bracket 31 is adjusted in real time through the linear drive cylinder 41 according to the obtained coil diameter so that the hydraulic expansion shaft 32 on the strip separating device 3 is always close to but not in contact with the strip and can be separated by the separator unit 33.

[0040] In this embodiment, the PLC control system 5 measures the linear speed of the coil and the rotation speed of the winding drum 21 of the strip winding mechanism 2 through a speed sensor or encoder, and calculates the coil diameter of the coil on the winding drum 21 in real time according to the following formula. Since the basic dimensions of the remaining structures are fixed and known, obtaining the coil diameter is equivalent to obtaining the specific value that needs to be adjusted by the swing drive mechanism 4. The swing drive mechanism 4 can adjust the angle θ by pushing the strip separating device bracket 31 through the linear drive cylinder 41 to ensure that the hydraulic expansion shaft 32 is always close to the strip but not in contact with it, so as to achieve the effect of avoiding wear of the strip.

[0041] D is the current coil diameter, V is the line speed, N is the roll speed (RPM), and π is a constant of 3.1416.

[0042] The first connection axis 61 between the center of the first articulated shaft 12 and the center axis of the hydraulic expansion shaft 32 intersects the circumference of the hydraulic expansion shaft 32 at one point, which is the tangent point of the hydraulic expansion shaft 32, and is the only intersection point of the first connection axis 61 on the circumference of the hydraulic expansion shaft 32. The angle between the first connection axis 61 and the second connection axis 62 between the center of the first articulated shaft 12 and the center of the winding drum 21 is θ.

[0043] θ= -1E-13D4 + 1E-09D3 - 2E-06D2 + 0.0256D + 1.769, Where D is the coil diameter, E is a constant, and the specific numerical results are shown in the table below. The PLC control system 5 adjusts the angle θ according to the coil diameter.

[0044] like Figure 5 As shown, the hydraulic expansion shaft 32 includes an inner shaft 321 and an outer shaft tube 322 sleeved on the inner shaft 321, and shaft necks 323 are fixed at both ends of the inner shaft 321 and the outer shaft tube 322. The outer diameter of the inner shaft 321 is less than or equal to the inner diameter of the outer shaft tube 322. An annular expansion tube liquid storage chamber 324 is provided between the inner shaft 321, the outer shaft tube 322 and the two shaft necks 323, which can cause the outer shaft tube 322 to radially expand when liquid enters. At least one end of the annular expansion tube liquid storage chamber 324 is connected to the rotating liquid supply component 36.

[0045] In this embodiment, the rotating liquid supply assembly 36 is responsible for introducing liquid into the annular expansion tube liquid storage chamber 324, thereby driving the expansion and contraction mechanism of the hydraulic expansion shaft 32. When the liquid fills the annular expansion tube liquid storage chamber 324, the chamber immediately drives the outer shaft tube 322 to expand outward and enter an expansion state. At this time, the overall diameter of the hydraulic expansion shaft 32 is significantly increased; on the contrary, when the liquid flows out of the annular expansion tube liquid storage chamber 324, the annular expansion tube liquid storage chamber 324 guides the outer shaft tube 322 to retract inward and present a contraction state. At this time, the overall diameter of the hydraulic expansion shaft 32 is correspondingly reduced.

[0046] More specifically, the rotary liquid supply assembly 36 includes a rotary liquid supply device 364 arranged on the outer end of the shaft neck 323, and the PLC control system 5 is connected to the rotary liquid supply device 364 to control the start and stop of the rotary liquid supply device 364. The shaft neck 323 is provided with a first liquid passage 361 axially passing through both ends thereof. The outer end of the first liquid passage 361 is connected to the rotary liquid supply device 364, and the inner end of the first liquid passage 361 is connected to the second liquid passage 362 of the inner shaft 321.

The second liquid passage 362 is connected to the annular expansion tube liquid storage chamber 324 through two radial liquid separation structures 365 distributed axially along the second liquid passage 362. The radial liquid separation structure 365 includes two radial liquid separation channels 366 distributed circumferentially along the second liquid passage 362. The inner end of the radial liquid separation channel 366 is connected to the second liquid passage 362, and the outer end is connected to the annular expansion tube liquid storage chamber 324.

[0049] In this embodiment, the plug 325 and the annular sealing ring 326 arranged on the plug 325 together form a multiple sealing structure, which not only provides an excellent sealing effect, but also enables the hydraulic expansion shaft 32 to provide a greater tensioning force, thereby ensuring the stability of the separator unit 33 during tensioning.

[0050] like Figure 6 As shown, the separator unit 33 includes a separator annular seat 331, and at least two semicircular arc separators 332 are distributed along the circumferential direction and tightly attached to each other in the circumferential direction on the outer wall of the separator annular seat 331. All the arc separators 332 are combined to form a separator ring 333, and the inner ends of the arc separators 332 are embedded in the annular separator mounting groove 334 of the separator annular seat 331 and fixed by a detachable structure 335.

[0051] In this embodiment, to avoid accidental collision, the thickness of the arc-shaped separator 332 gradually decreases from the outer end to the middle, and an arc-shaped chamfer is provided on the outer end of the arc-shaped separator 332. In addition, the detachable structure 335 is axially arranged on the separator annular seat 331 and the arc-shaped separator 332, and they are fixed by the countersunk bolts 336 connected by threads. To avoid interference and accidental scratches, the two ends of these countersunk bolts 336 are kept in the same plane with the surface of the separator annular seat 331.

[0052] More specifically, the claw driving mechanism 35 includes a slide rail 353 arranged on a claw driving frame 352, the upper end of the claw driving frame 352 is connected to the slide rail 353, and the lower end is fixedly connected to the side of the frame 1, a slide seat 354 is provided on the slide rail 353, and a lead screw 355 that can drive it to move along the slide rail 353 is passed through the slide seat 354, one end of the lead screw 355 is connected to a lead screw driver 356, and the PLC control system 5 is connected to the lead screw driver 356 to control the start and stop of the lead screw driver 356; an extension frame 357 is provided on the slide seat 354, and the extension frame 357 extends to one side from the slide seat 354, and a linear driver 358 is provided at the bottom of the end of the extension frame 357, the claw 351 is connected to the output end of the bottom of the linear driver 358, and the PLC control system 5 is connected to the linear driver 358 to control the extension and retraction of the output end of the linear driver 358.

[0053] In this embodiment, the pusher claw 351 includes a pusher claw base 3511, which is directly mounted on the output end of the linear drive 358. In order to ensure the service life, a reinforcing rib is designed on the pusher claw 351 to enhance the structural strength. In addition, a shaft body clearance notch 3512 is specially provided at the lower end of the pusher claw 351, so that the pusher claw 351 can be further inserted between the separator units 33, so that the contact area between the pusher claw 351 and the separator unit 33 becomes larger, so as to avoid scratches and to move the separator unit 33 more smoothly.

[0054] The non-contact metal strip damage-free automatic winding method comprises the following steps: S1, installing a number of strips to be separated onto the strip winding mechanism 2; S2, inputting the number of strips and the width of each strip into the PLC control system 5, controlling the claw driving mechanism 35 of the strip separation device 3 through the PLC control system 5, and moving the plurality of separator units 33 to the correct position through the claw 351, so that the plurality of separator units 33 can separate strips of corresponding number and corresponding width; S3, after the separator unit 33 has moved, the PLC control system 5 controls the rotating liquid supply assembly 36 to inject liquid into the hydraulic expansion shaft 32 to radially expand the separator unit 33, thereby completing the tensioning and positioning of the separator unit 33; S4. Start the equipment for winding. During this period, the PLC control system 5 calculates the coil diameter of the coil on the winding drum 21 through the linear speed of the coil and the rotation speed of the winding drum 21 of the strip winding mechanism 2. The linear speed of the coil is measured by a speed sensor or an encoder, and the rotation speed of the winding drum 21 is measured by a rotation speed encoder or a rotation speed sensor installed on the winding drum 21. According to the obtained coil diameter, the linear drive cylinder 41 is used to adjust the swing angle of the strip separating device bracket 31 in real time so that the hydraulic expansion shaft 32 on the strip separating device 3 is always close to the strip but not in contact with it and can be separated by the separator unit 33.

[0055] The working principle of this embodiment is as follows: first, the required spacing size is input into the PLC control system 5 through the interactive screen 52, and the PLC control system 5 controls the linear driver 358 of the pusher claw drive mechanism 35 to lift the pusher claw 351, and then the screw driver 356 accurately controls the pusher claw 351 to reach between the separator units 33 that need to be adjusted along the slide rail 353. At this time, the linear driver 358 drives the pusher claw 351 to penetrate between the separator units 33, and the linear driver 358 can use the pusher claw 351 to push the separator unit 33 to the specified position of the expansion shaft 32 according to the specified data.

[0056] When the separator unit 33 is located at the specified position, the PLC control system 5 controls the rotating liquid supply device 364 to transport the liquid to the annular expansion tube liquid storage chamber 324 along the first liquid passage 361, the third liquid passage 363, the second liquid passage 362 and the radial liquid separation channel 366 in sequence. At this time, the annular expansion tube liquid storage chamber 324 drives the hydraulic expansion shaft 32 to expand. Since the separator unit 33 is a rigid body, the pressure between the two gradually increases until the separator unit 33 can be fixed.

[0057] At this time, the PLC control system 5 controls the swing drive mechanism 4 to swing the strip separation device 3 to a suitable position, and the winding drum rotation drive assembly 22 drives the winding drum 21 to rotate and start winding the strip. While winding, the PLC control system 5 continuously calculates the angle θ that the linear drive cylinder 41 needs to adjust in real time through the data measured by the speed sensor or encoder, ensuring that the hydraulic expansion shaft 32 is always close to the strip but not in contact with it until the winding is completed.
