Once the correction range is exceeded, the machine needs to be stopped, and then the web to be corrected needs to be manually adjusted to the adjustment 0 point of the web-correcting device, that is, the center point of the correction range, and then the web is allowed to continue to be transported within the correction range of the web-correcting device. If the operation is not stopped and the web continues to move forward, it will cause errors in the next station, such as the wrong punching position, the wrong pasting position, or unqualified winding, which can easily cause the overall loss of the web.

[0042] The preferred embodiments described below are for example only, and those skilled in the art may think of other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0043] Those skilled in the art should understand that, in the disclosure of the specification, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0044] In conjunction with the instruction manual Figures 1 to 4 According to a preferred embodiment of the present invention, a deflection roller displacement correction device is used to correct the position of the coil 1 during the process of conveying the coil. The correction device includes a correction roller 100, a support seat 200 and a sensing device 2. The correction roller 100 is rotatably arranged on the support seat 200, wherein preferably, there are two support seats 200, which are respectively arranged at the two ends of the correction roller 100 to facilitate the deflection of the correction roller 100. The sensing device 2 is close to the output position of the correction roller 100. When the coil 1 comes over, it first passes through the sensing range of the sensing device 2. Once the sensing device 2 senses that the coil 1 deviates from the predetermined position, the sensing device 2 sends a signal to the correction roller 100 for corresponding correction. The sensing device 2 is preferably a correction sensor, which is respectively arranged on both sides of the traveling direction of the coil 1 to sense the traveling position of the coil 1.

[0045] The correcting roller 100 includes a core shaft 10, a roller surface 50, at least one deflection disk 30, at least one supporting roller 40 and at least one driving device 60, wherein the core shaft 10 is rotatably arranged on the two supporting seats 200, and the driving device 60 cooperates with the deflection disk 30 and has a driving end 61 that drives the corresponding deflection disk 30 to deflect along the axial direction of the core shaft 10.

[0046] In conjunction with the instruction manual Figures 5 to 7 The roller surface 50 is composed of a plurality of support strips 51. The plurality of support strips 51 form a cylindrical roller surface 50 along the circumference of the mandrel 10 to facilitate the conveying of the coil 1. The inner side of the support strip 51 close to the mandrel 10 is provided with an installation positioning groove 511, wherein preferably, the installation positioning grooves 511 on the plurality of support strips 51 are uniformly arranged along the radial direction of the mandrel 10.

[0047] The deflection plate 30 is rotatably and swingably sleeved on the core shaft 10, and the outer ring of the deflection plate 30 is circumferentially provided with a toggle protrusion 31 which can be correspondingly installed in the installation positioning groove 511. The toggle protrusion 31 is loosely matched with the installation positioning groove 511 so as to toggle the support strip 51 when deviation correction is required.

[0048] It is worth mentioning that the “rotational swing” means that the deflection disk 30 can not only rotate freely on the core shaft 10 in a direction perpendicular to the core shaft 10, with the friction between the coil 1 and the roller surface 50 forming the driving force for the rotation of the deflection disk 30; it can also swing in a direction forming a predetermined angle with the core shaft 10, with the driving force for the swing being provided by the drive device 60.

[0049] As a preferred embodiment of the present application, the deflection plate 30 includes a sleeve 32, a spherical bearing 33, a first rolling bearing 34 and a bearing cover 35. The sleeve 32 is fixedly sleeved on the core shaft 10. The inner ring of the spherical bearing 33 is fixedly sleeved on the sleeve 32. The inner ring of the first rolling bearing 34 is fixedly sleeved on the outer ring of the spherical bearing 33. The bearing cover 35 is sleeved on the outer ring of the first rolling bearing 34.

[0050] The spherical bearing 33 is used to realize the deflection of the deflection disc 30 at a predetermined angle relative to the core shaft 10, and the first rolling bearing 34 is used to realize the rotation of the deflection disc 30 relative to the core shaft 10. When the spherical bearing 32 does not deflect, the deflection disc 30 rotates perpendicular to the core shaft 10; when the spherical bearing 32 deflects at a certain angle, the deflection disc 30 performs a corresponding deflection rotation along the deflection angle of the spherical bearing 33 under the action of the first rolling bearing 34. The spherical bearing 33 is preferably a spherical bearing.

[0051] In the deflection roller displacement correction device, the shifting protrusion 31 is arranged on the outer ring of the bearing cover 35. The driving end 61 is fixedly connected to the side surface of the outer ring of the spherical bearing 33.

[0052] It is worth mentioning that, considering the length of the mandrel 10 and / or the weight of the coil 1, the number of the deflection disc 30 needs to be at least one. When there is only one deflection disc 30, it is best to set the deflection disc 30 near the middle of the mandrel 10, or directly set it in the middle of the mandrel 10. Obviously, it can be understood by those skilled in the art that two or more deflection discs 30 can also be set. All the deflection discs 30 move synchronously to provide a greater deflection force. Obviously, the number of the driving devices 60 corresponds to the number of the deflection discs 30, and each driving device 60 also drives the corresponding deflection disc 30 synchronously.

[0053] The support roller 40 is rotatably sleeved on the core shaft 10, and the outer ring of the support roller 40 is circumferentially provided with a limiting groove 41 for accommodating the corresponding support strip 51. When the toggle protrusion 31 toggles the support strip 51, the limiting groove 41 is used to ensure that the support strip 51 can only translate along the axial direction of the core shaft 10, thereby ensuring the normal conveyance of the coil 1.

[0054] It is worth mentioning that the number of support rollers 40 can also be set to one or more than two. When there is only one support roller 40, the support and limiting functions of the support roller 40, together with the driving function of the deflection plate 30, can support and limit the roller surface 50, and still complete the continuous correction function of the deflection roller displacement correction device. When the number of support rollers 40 is more than two, it is often used for a longer mandrel 10, so as to form support and limit the roller surface 50 at multiple points in the axial direction of the mandrel 10.

[0055] As a preferred embodiment of the present application, there are two support rollers 40 , and the two support rollers 40 are respectively close to the two ends of the core shaft 10 to simultaneously support and limit the roller surface 50 at the two ends of the core shaft 10 .

[0056] Preferably, the support roller 40 includes a second rolling bearing 42 and a bearing end cover 43. The second rolling bearing 42 is fixedly sleeved on the core shaft 10. The bearing end cover 43 is fixedly sleeved on the outer ring of the second rolling bearing 42. The limiting groove 41 is provided on the outer ring of the bearing end cover 43. The rotation of the support roller 40 relative to the core shaft 10 is achieved by the second rolling bearing 42.

[0057] As a preferred embodiment of the present application, the deflection roller displacement correction device also includes a clamping sleeve 70 and a protective cover 80 that cooperate with the support roller 40.

[0058] The cross section of the compression sleeve 70 is in a transverse T-shape. The compression sleeve 70 is fixedly sleeved on the core shaft 10 and is located between the support seat 20 and the support roller 40. The protruding parts of the compression sleeve 70 are respectively away from the corresponding support rollers 40.

[0059] The protective cover 80 is composed of a circular cover plate 81 and a cover shell 82 which is integrally formed and vertically extends along the circumference of the cover plate 81. The cover plate 81 is fixedly sleeved on the core shaft 10. The inner side surface of the cover plate 81 is fixedly connected to the protruding portion of the clamping sleeve 70, so that the protective cover 81 is fixed through the clamping sleeve 70 to prevent the protective cover 80 from deflecting or vibrating during the rotation of the core shaft 10. The cover shell 82 faces the supporting roller 40, and the inner side surface of the cover shell 82 is close to the outer ring of the bearing end cover 43, so as to form an annular groove space in the circumferential direction to accommodate the roller surface 50.

[0060] The protective cover 80 can effectively protect the outer side of the support roller 40 from being affected by foreign matter such as dust, so as to increase the service life of the support roller 40; at the same time, the protective cover 80 and the bearing end cover 43 cooperate to further limit the roller surface 50.

[0061] The driving device 60 is fixedly mounted on the core shaft 10. The driving end 61 of the driving device 60 is fixedly connected to the side of the deflection disc 30, so as to drive the deflection disc 30 to deflect by a predetermined angle when the deflection disc 30 rotates around the core shaft 10, so as to correct the deviation of the coil 1.

[0062] It is worth mentioning that the driving device 60 is preferably a correction motor. Obviously, the correction motor includes not only a synchronous motor, but also a DC motor or a stepper motor. After the driving device 60 receives the control signal from the induction device 2, it drives the corresponding deflection disk 30 to perform the correction action.

[0063] It is worth mentioning that the support strip 51 is composed of a support plate 512 near the outside and a limiting body 513 near the inside. The outer side surface of the support plate 512 is arc-shaped, so that a cylindrical roller surface 50 is formed by a plurality of the support strips 51. The limiting body 513 is adapted to the limiting groove 41 to ensure that the support strip 51 can only translate along the axial direction parallel to the core shaft 10.

[0064] As a preferred embodiment of the present application, the position limiting body 513 is a position limiting plate integrally connected to the inner side of the support plate 512. The position limiting body 513 is symmetrically provided with a clamping groove 513-1 along the arc direction of the support plate 512.

[0065] Correspondingly, the cross section of the limiting groove 41 is in an inverted T-shape, which matches with the limiting body 513 and the two clamping grooves 513 - 1 respectively. The support strip 51 is axially limited by the plate-shaped limiting body 513 .

[0066] As another preferred embodiment of the present application, the limiting body 513 is a limiting cylinder fixedly connected to the inner side of the support plate 512. The cross section of the limiting groove 41 is a circle with an opening. The opening is adapted to the connection portion between the limiting cylinder and the support plate 512. The support strip 51 is axially limited by the cylinder.

[0067] It is worth mentioning that a friction plate 514 is installed along the axial direction on the outer side of the support plate 512 to increase the friction force of the roller surface 50. The friction plate 512 is preferably a nylon or a metal plate with a sandblasted surface. Obviously, based on the purpose of improving the efficiency of conveying the coil 1 through the friction principle, technicians in this technical field may also think of other means to achieve this purpose, such as using a wooden board, or wrapping a material with a large friction coefficient by fixing means such as plating or bonding on a metal plate.

[0068] Specifically, in the process of conveying the coil 1 through the deflection roller displacement correction device, once the sensing device 2 senses that the coil 1 deviates from the predetermined position, the sensing device 2 will send a signal to the correction roller 100, and the driving device 60 in the correction roller 100 will drive the deflection plate 30 to deflect by a predetermined angle. Under normal circumstances, the deflection of the deflection plate 30 will inevitably cause the height difference of the support strip 51 on the virtual circle where the original cylindrical roller surface 50 is located. In order to overcome this situation, the present application uses the clearance fit between the toggle protrusion 31 and the installation positioning groove 511, that is, the toggle protrusion 31 has a certain activity space in the installation positioning groove 511, and the support strip 51 cooperates with the limiting groove 41 in the axial direction. Under the limiting action of the limiting groove 41, the support strip 51 performs corresponding activities on the toggle protrusion 31 through the installation positioning groove 511, so that the support strip 51 can only translate in the axial direction, thereby well overcoming the above situation, so as to facilitate the continuous conveying of the coil 1 on the same circular surface. During the correction process, the corresponding toggle protrusion 31 on the deflection disc 30 drives the corresponding support strip 51 on the roller surface 50 to move the corresponding displacement along the axial direction at the corresponding speed. Since the deflection disc 30 continues to rotate on the core shaft 10, the support strip 51 on the roller surface 50 will continue to move accordingly until it rotates one circle and then moves again at the same speed in the next circle, thus driving the coil 1 to continuously deflect on the roller surface 50. In theory, as long as the core shaft 10 and the roller surface 50 are of sufficient length, as long as the deflection disc 30 continues to deflect in the same direction, the coil 1 will be corrected in the same direction all the time, and there is no limitation on the maximum correction stroke size in the conventional correction device. Of course, according to actual needs, as long as the coil 1 is corrected to the appropriate position, the deflection disc 30 will be reset to the direction perpendicular to the core shaft 10, or deflected a little bit in the opposite direction to fine-tune the position of the coil 1.

[0069] It should be noted that the terms "first, second" in the present invention are only used for descriptive purposes and do not indicate any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.

[0070] It should be understood by those skilled in the art that the embodiments of the present invention described above are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
