Description

Technical Field

[0001] This invention belongs to the technical field of flat strip processing equipment, and specifically relates to an automatic winding system and an automatic winding method. Background Technology

[0002] With the development of industry, automated equipment has become widespread in all walks of life, especially in the winding equipment for flat strip processing. The emergence of automated equipment has greatly reduced the labor costs in factories and improved production efficiency.

[0003] Nowadays, many automated winding equipment has emerged on the market, such as the Chinese invention patent with application number 202111516060.5—a fully automatic packing tape winding device, which discloses a winding device that can automatically wind packing tape onto rollers.

[0004] When the aforementioned fully automatic packing tape winding device winds up the packing tape, a person manually places the built-in container paper core for winding the flat strip material onto the roller. Then, the winding equipment pulls the flat strip material onto the paper core for winding. After winding is completed, the rolled tape is unloaded, and a person manually reinstalls the paper core for the next round of winding.

[0005] This shows that in existing automatic winding equipment, the paper core used for winding is replaced manually. In practical applications, the paper core used for winding is usually purchased from external suppliers or produced using specialized paper core manufacturing equipment, and then replaced manually. When the paper core and flat strip are wound by different equipment, manual transfer and installation of the paper core is required. This results in insufficient automation and reduced winding efficiency in existing winding equipment.

[0006] Therefore, existing technologies need to be improved and developed. Summary of the Invention

[0007] The purpose of this application is to provide an automatic winding system and method that enables the winding of paper cores and flat strips to be concentrated on the same equipment, eliminating the need for manual transfer and installation of paper cores, thereby improving the automation and efficiency of winding.

[0008] This application provides an automatic winding system, including a fixing component, a paper roll component, a tape roll component, and a winding component for winding up the paper blank released from the paper roll component and the flat strip material released from the tape roll component;

[0009] The winding assembly includes a rotating roller, a first driving component for driving the rotating roller to rotate, and a second driving component for driving the rotating roller to extend and retract along the axial direction of the rotating roller.

[0010] The fixing component is used to fix the free end of the flat strip to the paper core formed by winding the paper blank;

[0011] It also includes a controller, which includes at least:

[0012] The first control module controls the rotation of the rotating roller after the paper blank is wound to form the paper core, rotates the bonding overlap section on the paper core to the fixed position of the fixing component, and controls the fixing component to fix the free end of the flat strip material on the bonding overlap section.

[0013] By setting up a fixing component, a paper winding component, a tape winding component, and a winding component on an automatic winding system, the functions of winding paper cores and flat strips can be realized on the same equipment, saving the time of manually transferring paper cores and manually feeding them, and improving winding efficiency. The winding component includes a rotating roller. A first drive component drives the rotating roller to rotate to wind the paper blank and flat strip. A second drive component drives the rotating roller to extend and retract along its axial direction, so that after winding is completed, the rotating roller automatically unloads the paper core and flat strip without manual unloading, improving production efficiency. The fixing component is used to fix the free end of the flat strip to the paper core, allowing the flat strip to be better wound onto the paper core through the fixing point. Furthermore, by setting up the fixing component, the manual labor of winding the flat strip onto the paper core can be saved, improving the automation level of the winding equipment and increasing production efficiency. The automatic winding system also includes a controller, which comprises a first control module. After the paper blank is wound into a paper core, the first control module controls the rotating roller to rotate, moving the adhesive overlap section on the paper core to the fixed position of the fixing component. This allows the fixing component to fix the free end of the flat strip to the adhesive overlap section of the paper core. Since the paper blank has just been wound into a paper core, the adhesive on the adhesive overlap section has not yet fully cured. If the flat strip is fixed to other parts of the paper core, the tension generated by the flat strip during winding may pull the wound paper core apart from the paper blank. To avoid this problem, the fixing component fixes the free end of the flat strip to the adhesive overlap section of the paper core. This not only fixes the flat strip to the paper core during winding but also further reinforces the adhesive overlap section of the paper core, improving winding quality. Therefore, the automatic winding system proposed in this application enables the winding of paper cores and flat strips to be concentrated on the same equipment, eliminating the need for manual transfer and installation of paper cores, thus improving winding automation and efficiency.

[0014] Furthermore, the controller also includes a second control module: used to control the second drive component to drive the rotating roller to retract and unload the paper core and the flat strip wound on the paper core after the flat strip is wound up.

[0015] By setting up a second control module, after the flat strip is wound up, the second drive component is controlled to drive the rotating roller to shrink and unload the paper core and flat strip. This eliminates the need for manual disassembly and operation of the wound material, thereby improving the automation level of the winding equipment and saving manpower.

[0016] Furthermore, the roll assembly includes a paper feed tray for discharging the paper blank, a cutter component for cutting the paper blank, and a dispensing component for applying glue to the end of the cut paper blank.

[0017] The controller also includes a third control module: when the length of the paper blank released is longer than the circumference of the outer circumference of the rotating roller and can be wound around the rotating roller to form a paper core, the controller controls the cutting component to cut the paper blank and controls the dispensing component to apply glue to the cut end of the paper blank.

[0018] The fourth control module is used to control the rotation of the rotating roller when the first end of the paper blank is adsorbed onto the rotating roller, so that the paper blank is wound on the rotating roller and the end of the paper blank adheres to the first end to form a paper core.

[0019] The fourth control module includes:

[0020] First acquisition element: Taking the initial position of the adsorption component on the rotating roller as the starting point of rotation, the number of rotations of the rotating roller is acquired in real time;

[0021] First control element: used to adjust the rotation speed of the rotating roller according to the number of rotations of the rotating roller, so that when the rotating roller finishes winding the paper core and rotates the overlapping section on the paper core to the fixed position where the fixed component is located, the rotation speed is 0, so as to connect the flat strip material for winding.

[0022] By setting a fourth control module to control the rotation speed of the rotating roller, the paper blank can be more smoothly wound around the outer circumference of the rotating roller to form a paper core. The fourth control module includes a first acquisition element. The first acquisition element takes the initial position of the adsorption component on the rotating roller as the starting point of rotation. The function of the adsorption component is to adsorb the first end of the paper blank. Its initial position is the tangent point where the bottom of the rotating roller is tangent to the horizontal plane (which is also the location of the bonding overlap section). The rotating roller rotates to wind up the paper blank from this initial position. The paper blank only needs to be wound around the rotating roller once to achieve the bonding of the beginning and end to form a paper core. After the paper blank forms a paper core, the first control element controls the rotating roller to continue to decelerate until the bonding overlap section rotates to the fixed position of the fixing component. The rotation speed of the rotating roller is reduced to 0 so that the fixing component can fix the flat strip material on the paper core for subsequent winding.

[0023] Furthermore, the first control element includes:

[0024] Second control element: used to control the rotating roller to wind at a first winding speed when the paper blank is connected to the rotating roller;

[0025] The third control element is used to control the rotating roller to decelerate at the first deceleration acceleration when the rotating roller has rotated 3 / 4 of a turn, so that the rotating roller completes the winding of the paper core and rotates the pasted overlapping section on the paper core to the fixed position where the fixed component is located, and the rotation speed is 0.

[0026] The first control element controls the rotation speed of the rotating roller in the following way: when the paper blank is initially adsorbed onto the rotating roller, the second control element controls the rotating roller to quickly wind it up at the first winding speed. Then, when the rotating roller has rotated 3 / 4 of a turn, the third control element controls the rotation speed of the rotating roller to gradually decrease from the first winding speed until the two ends of the paper blank are fixed with glue at the bonding overlap section to form the paper core. At this point, the rotating roller continues to decelerate until the bonding overlap section rotates to the fixing position of the fixing component. The rotation speed of the rotating roller then decreases to 0, which makes it easier for the fixing component to fix the flat strip material onto the paper core.

[0027] Furthermore, the controller also includes:

[0028] The second acquisition module is used to acquire the real-time position of the adsorption component after the flat strip is wound up;

[0029] The fifth control module is used to adjust the rotation direction of the rotating roller according to the real-time position and the initial position, so that the adsorption component is reset to the starting point of rotation.

[0030] Secondly, this application provides an automatic winding method for controlling an automatic winding system to perform winding. The automatic winding system includes a fixing component, a paper roll component, a tape roll component, and a winding component for winding the paper blank released by the paper roll component and the flat strip material released by the tape roll component.

[0031] The winding assembly includes a rotating roller, a first driving component for driving the rotating roller to rotate, and a second driving component for driving the rotating roller to extend and retract along the axial direction of the rotating roller.

[0032] The fixing component is used to fix the free end of the flat strip to the paper core formed by winding the paper blank;

[0033] The method includes the following steps: after the paper blank is wound to form the paper core, the rotating roller is controlled to rotate, the bonding overlap section on the paper core is rotated to the fixed position of the fixing component, and the fixing component is controlled to fix the free end of the flat strip material on the bonding overlap section.

[0034] Furthermore, the method also includes the following steps:

[0035] After the flat strip is wound up, the second drive unit is controlled to drive the rotating roller to retract and unload the paper core and the flat strip wound on the paper core.

[0036] Furthermore, the roll assembly includes a paper feed tray for discharging the paper blank, a cutter component for cutting the paper blank, and a dispensing component for applying adhesive to the end of the cut paper blank.

[0037] The method further includes the steps of: when the length of the paper blank released is longer than the circumference of the outer circumference surface of the rotating roller and can be wound around the rotating roller to form a paper core, controlling the cutting component to cut the paper blank, and simultaneously controlling the glue dispensing component to apply glue to the cut end of the paper blank;

[0038] When the first end of the paper blank is adsorbed onto the rotating roller, the rotating roller is controlled to rotate, so that the paper blank is wound up on the rotating roller, and the end of the paper blank adheres to the first end to form a paper core.

[0039] When the first end of the paper blank is adsorbed onto the rotating roller, the rotating roller is controlled to rotate, causing the paper blank to be wound up on the rotating roller, and the end of the paper blank adheres to the first end to form the paper core. The steps include:

[0040] The number of rotations of the rotating roller is obtained in real time, taking the initial position of the adsorption component on the rotating roller as the starting point of rotation.

[0041] The rotation speed of the rotating roller is adjusted according to the number of rotations of the rotating roller. When the rotating roller finishes winding the paper core and rotates the overlapping section on the paper core to the fixed position where the fixed component is located, the rotation speed is 0, so as to connect the flat strip material for winding.

[0042] Furthermore, the rotation speed of the rotating roller is adjusted according to the number of rotations of the rotating roller, so that when the rotating roller finishes winding the paper core and rotates the overlapping section on the paper core to the fixed position where the fixed component is located, the rotation speed is 0, and the flat strip is connected for winding, including the following steps:

[0043] When the paper blank is connected to the rotating roller, the rotating roller is controlled to wind up at a first winding speed;

[0044] When the rotating roller has rotated 3 / 4 of a turn, the rotating roller is controlled to decelerate at the first deceleration acceleration, so that the rotating roller completes the winding of the paper core and rotates the pasted overlapping section on the paper core to the fixed position where the fixed component is located, at which point the rotation speed is 0.

[0045] Furthermore, the method also includes the following steps:

[0046] After the flat strip is wound up, the real-time position of the adsorption component is obtained;

[0047] Adjust the rotation direction of the rotating roller according to the real-time position and the initial position to reset the adsorption component to the starting point of rotation.

[0048] As can be seen from the above, the automatic winding system and method provided in this application, by setting a fixing component, a paper winding component, a tape winding component, and a winding component on the automatic winding system, can realize the function of winding paper cores and flat strip materials on the same equipment, saving the time of manually transferring paper cores and manually feeding paper cores, and improving winding efficiency. The winding component includes a rotating roller. A first driving component drives the rotating roller to rotate to realize the function of winding paper blanks and flat strip materials. A second driving component drives the rotating roller to extend and retract along the axial direction of the rotating roller, so that after the rotating roller completes winding, it automatically unloads the paper core and flat strip materials without manual unloading, improving production efficiency. The fixing component is used to fix the free end of the flat strip material to the paper core, so that the flat strip material is better wound on the paper core through the fixing point. Furthermore, by setting the fixing component, the manual labor of winding the flat strip material onto the paper core can be saved, improving the automation level of the winding equipment and increasing production efficiency. The automatic winding system also includes a controller, which comprises a first control module. After the paper blank is wound into a paper core, the first control module controls the rotating roller to rotate, moving the adhesive overlap section on the paper core to the fixed position of the fixing component. This allows the fixing component to fix the free end of the flat strip to the adhesive overlap section of the paper core. Since the paper blank has just been wound into a paper core, the adhesive on the adhesive overlap section has not yet fully cured. If the flat strip is fixed to other parts of the paper core, the tension generated by the flat strip during winding may pull the wound paper core apart from the paper blank. To avoid this problem, the fixing component fixes the free end of the flat strip to the adhesive overlap section of the paper core. This not only fixes the flat strip to the paper core during winding but also further reinforces the adhesive overlap section of the paper core, improving winding quality. Therefore, the automatic winding system proposed in this application enables the winding of paper cores and flat strips to be concentrated on the same equipment, eliminating the need for manual transfer and installation of paper cores, thus improving winding automation and efficiency.

[0054] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0055] The following disclosure provides many different embodiments or examples for implementing different structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0056] Currently, flat sheet materials are typically wound onto paper cores. The winding equipment for the formed paper core and the flat sheet material is usually two separate devices. In practice, after the paper blank is wound into shape on the paper core winding equipment, the formed paper core is manually transferred and installed onto the rotating rollers for winding the flat sheet material. This method not only involves complex winding equipment but also has a low degree of automation, hindering production efficiency. To address this problem, this application provides an automatic winding system and an automatic winding method.

[0057] like Figure 1 , Figure 2 As shown, an automatic winding system includes a fixing component 5, a paper roll component 2, a tape roll component 3, and a winding component 4 for winding the paper blank released from the paper roll component 2 and the flat strip material released from the tape roll component 3.

[0058] The winding assembly 4 includes a rotating roller 41, a first driving component 43 for driving the rotating roller 41 to rotate, and a second driving component 44 for driving the rotating roller 41 to extend and retract along the axial direction of the rotating roller 41.

[0059] The fixing component 5 is used to fix the free end of the flat strip to the paper core formed by winding the paper blank;

[0060] It also includes a controller, which includes at least:

[0061] The first control module controls the rotating roller 41 to rotate after the paper blank is wound to form the paper core, so as to rotate the pasting overlap section on the paper core to the fixed position of the fixing component 5, and controls the fixing component 5 to fix the free end of the flat strip material on the pasting overlap section.

[0062] In practical applications, both winding paper cores and winding flat strips on paper cores can be achieved on this automatic winding system. This automatic winding system integrates the winding functions of paper cores and flat strips onto the same equipment, greatly simplifying the composition of the winding equipment and reducing its footprint. Compared with the existing technology that uses different equipment to wind paper cores and flat strips separately, this automatic winding system not only saves the manpower and time costs of manually transferring and installing paper cores, but also significantly reduces the operating costs of purchasing paper core winding equipment or externally purchasing paper cores for manufacturers whose main products are not paper cores.

[0063] The automatic winding system includes a fixing component 5, a paper winding component 2, a tape winding component 3, and a winding component 4. The paper winding component 2 includes a cutter component and an adhesive dispensing component. The cutter component cuts the paper blank when the sensor detects that the unwound length is sufficient to wind around the rotating roller to form a paper core. The adhesive dispensing component applies adhesive to the cut end of the paper blank after the cutter component, facilitating adhesion and fixation between the paper blank and the beginning of the paper blank when wound into a paper core. The winding component 3 also includes an adsorption component 42 mounted on the rotating roller 41 and a pressure roller located below the rotating roller 41. The pressure roller is connected to a drive device and moves closer to or further away from the rotating roller 41 under the drive of the drive device. The pressure roller approaches the rotating roller 41 when the end of the paper blank is about to adhere to the beginning, rolling the overlapping section of the paper blank to improve the paper core formation. After the paper core is formed, the pressure roller moves away from the rotating roller 41 to avoid interference with the winding of the flat tape. In specific applications, the paper roll assembly 2 is used to release the paper blank. The free end of the paper blank is transported to the position of the rotating roller 41 of the winding assembly 4. The adsorption component 42 on the rotating roller 41 adsorbs the first end of the paper blank onto the outer circumferential surface of the rotating roller 41 to rotate and wind it into a paper core. The length of the paper blank released is slightly longer than the circumference of the outer circumferential surface of the rotating roller 41. After the paper blank is wound around the outer circumferential surface of the rotating roller 41 once, the end of the paper blank overlaps and adheres to the first end. The cutting component in the paper roll assembly 2 will then cut the paper blank. The glue dispensing component located on one side of the cutting component will apply glue to the end of the paper blank, so that after the paper blank is wound around the outer circumferential surface of the rotating roller 41 once, the end of the paper blank can adhere to the first end of the paper blank through the glue attached thereon. The adhesion part is the overlapping section.

[0064] In specific applications, the tape assembly 3 is used to release the flat tape, which needs to be wound onto the paper core to form a tape for subsequent packaging, transportation and sales. Because the effect of applying glue to the free end of the flat strip material on the tape assembly 3 to bond it to the paper core is not ideal, the free end of the flat strip material is difficult to fix to the paper core for winding. In the prior art, the free end of the flat strip material is usually wound manually onto the paper core and then wound up using a winding device. This manual winding method has a low degree of automation and wastes a lot of time, which is not conducive to improving production efficiency. In the automatic winding device of this application, the free end of the flat strip material is fixed by setting a fixing component 5, which can improve the automation process of the winding process. Specifically, when the tape assembly 3 transports the free end of the flat strip material to the position of the rotating roller 41, the fixing component 5 set on one side of the rotating roller 41 uses a nail to nail the free end of the flat strip material to the paper core, thereby fixing the flat strip material to the paper core and making it easier for the flat strip material to be wound onto the paper core.

[0065] In specific applications, the rotating roller 41 is also connected to a first drive component 43 and a second drive component 44. The first drive component 43 can be a servo motor, which drives the rotating roller 41 to rotate through a rotating shaft passing through the axis of the rotating roller 41. The second drive component 44 can be a servo electric cylinder. The rotating roller 41 can be mounted on a slide rail through a mounting base. The servo electric cylinder is connected to the mounting base and drives the rotating roller 41 to extend and retract in the axial direction. When the rotating roller 41 extends, it winds up the paper blank and flat strip. When the rotating roller 41 retracts, it can unload the material wrapped on the rotating roller 41. In order to reduce the footprint of the automatic winding system, a cavity can be opened inside the frame 1 of the automatic winding system to accommodate the rotating roller 41. When the rotating roller 41 retracts, it can be retracted into the cavity inside the frame 1, which can easily unload the wound material and avoid the rotating roller 41 occupying extra space due to the need for extension and retraction. To better unload materials, the automatic winding system also includes an unloading component 6, which is located directly below the rotating roller 41 and has a U-shaped clamp 61. After the material is wound up, the unloading component 6 approaches the rotating roller 41 and clamps the material (paper core and flat strip wound on the paper core) into the U-shaped clamp 61. The rotating roller 41 retracts, and the unloading component 6 unloads the material and transports it to the unloading component for discharge. No manual assistance is required, and the automation level of the equipment is greatly improved.

[0066] In specific applications, the automatic winding system also includes a controller, which can be a PLC device. The controller includes at least a first control module. After the paper blank is wound to form a paper core, the first control module controls the rotating roller 41 to continue rotating until the bonding overlap section on the paper core corresponds to the fixed station where the fixing component 5 is located, thereby facilitating the fixing component 5 to fix the flat strip material at the bonding overlap section of the paper core. The overlapping section refers to the overlapping part where the ends of the paper blanks are connected. The fixing component 5 fixes the flat strip to the overlapping section of the paper core. The pin passes through the flat strip and the two layers of paper blanks to fix the flat strip to the paper core (the fixing component 5 is a conventional component for fixing, which can fix the pin to the object by telescopic means, and its structure will not be described in detail here). On the one hand, it can strengthen the connection between the ends of the paper core. On the other hand, since the bonding time between the ends of the paper core is short, the glue may not be completely cured. If the flat strip is fixed to other parts of the paper core, the flat strip will generate tension along the winding direction during the winding process, pulling the paper core apart into paper blanks, affecting the winding process. Therefore, in order to improve the winding quality, the flat strip can be fixed to the overlapping section.

[0067] Compared to existing flat strip winding processes, this application integrates the winding functions of paper cores and flat strips onto a single winding machine. This saves manpower and time costs associated with manually transferring and installing paper cores. Furthermore, the automatic winding system incorporates a fixing component 5 that secures the flat strip to the paper core during winding, eliminating the need for manual assistance and improving production automation. Moreover, when fixing the flat strip, the fixing component 5 is positioned at the overlapping section of the paper core to prevent the paper core from breaking during winding, thus improving production quality. Therefore, the automatic winding system provided by this application enables the winding of paper cores and flat strips to be concentrated on the same machine, eliminating the need for manual transfer and installation of paper cores, and improving winding automation and efficiency.

[0068] In some specific embodiments, the controller further includes a second control module for controlling the second drive component 44 to drive the rotating roller 41 to retract and unload the paper core and the flat strip wound on the paper core after the flat strip is wound up.

[0069] In practical applications, the controller also includes a second control module. By setting the second control module, after the flat strip is wound up, the second drive component 44 drives the rotating roller 41 to shrink and unload the paper core and flat strip. This eliminates the need for manual disassembly and operation of the wound material, thereby improving the automation level of the winding equipment and saving manpower.

[0070] In some preferred embodiments, the paper roll assembly 2 includes a paper feed tray for discharging paper blanks, a cutter component for cutting the paper blanks, and an adhesive dispensing component for applying adhesive to the ends of the cut paper blanks.

[0071] The controller also includes a third control module: when the length of the paper blank released is longer than the circumference of the outer circumference of the rotating roller 41 and can be wound around the rotating roller 41 to form a paper core, the controller controls the cutting component to cut the paper blank and controls the dispensing component to apply glue to the cut end of the paper blank.

[0072] The fourth control module is used to control the rotation of the rotating roller 41 when the first end of the paper blank is adsorbed onto the rotating roller 41, so that the paper blank is wound on the rotating roller 41 and the end of the paper blank adheres to the first end to form a paper core.

[0073] The fourth control module includes:

[0074] First acquisition element: Taking the initial position of the adsorption component 42 on the rotating roller 41 as the starting point of rotation, the number of rotations of the rotating roller 41 is acquired in real time;

[0075] First control element: used to adjust the rotation speed of the rotating roller 41 according to the number of rotations of the rotating roller 41, so that when the rotating roller 41 finishes winding the paper core and rotates the pasted overlapping section on the paper core to the fixed position where the fixed component 5 is located, the rotation speed is 0, so as to connect the flat strip material for winding.

[0076] In practical applications, the paper roll assembly 2 is set on the frame to convey the paper blank. When the length of the paper blank discharged is slightly greater than the length of the rotating roller 41 and can form a paper core around the rotating roller 41, the third control module controls the cutting component to cut the paper blank. At the same time, the glue dispensing component applies glue to the end of the cut paper blank. Therefore, in order to make the cutting and gluing operation more convenient, the cutting component and the glue dispensing component can be set side by side, and the glue dispensing component is closer to the rotating roller than the cutting component, so that the glue dispensing component can apply glue to the end of the cut paper blank after the paper blank is cut.

[0077] The automatic winding system incorporates a paper roll assembly 2 in conjunction with a rotating roller 41 to automatically wind the paper blank into a paper core, saving the time required for manual loading of the paper core onto the rotating roller 41. Compared to existing winding equipment, the automatic winding system proposed in this application allows the paper blank to undergo conveying, cutting, and gluing processes, and then be wound by adsorbing it onto the outer circumferential surface of the rotating roller 41 using an adsorption component 42. The paper blank is wound only once during winding, allowing the two ends of the paper blank to be bonded together with glue, automatically forming a paper core. This improves winding efficiency and significantly reduces labor costs in the production process.

[0078] In practical applications, the fourth control module controls the rotation speed of the rotating roller 41, ensuring that the paper blank, after being adsorbed onto the outer circumferential surface of the rotating roller 41, can be smoothly wound into a paper core, which is then connected to the flat strip for winding. The fourth control module includes a first acquisition element, which can be an encoder. The encoder is connected to the rotating shaft in the rotating roller 41 via a transmission sprocket to acquire the number of rotations of the rotating shaft, thereby calculating the number of rotations of the rotating roller 41. The first control element can adjust the rotation speed of the rotating roller 41 according to the number of rotations of the rotating roller 41. When the paper blank is just adsorbed onto the outer circumferential surface of the rotating roller 41 by the adsorption component 42, the rotating roller 41 is controlled to rotate at a faster speed to speed up the winding efficiency. After the paper blank is wound to a certain extent, the rotation speed is reduced to avoid the centrifugal force on the paper blank being too large due to the excessive rotation speed of the rotating roller 41, making it difficult to adhere to the outer circumferential surface of the rotating roller 41 for winding. The rotating roller 41 gradually reduces its rotation speed. When the end of the paper blank overlaps and contacts the beginning, the pressure roller in the paper winding assembly 2 approaches the rotating roller 41 to press the end of the paper blank firmly against the beginning to form the paper core. After the paper core is formed from the paper blank, flat strips are connected to the paper core for winding. In order to facilitate the fixation of the free end of the flat strips to the paper core, when the overlapping section of the paper core rotates to the fixed position of the fixing component 5, the rotation speed of the rotating roller 41 can be reduced to 0. After the fixing component 5 fixes the flat strips to the paper core, the first control element controls the rotating roller 41 to increase the rotation speed and wind up the flat strips.

[0079] In some specific embodiments, the first control element includes:

[0080] Second control element: used to control the rotating roller 41 to wind at a first winding speed when the paper blank is connected to the rotating roller 41;

[0081] The third control element is used to control the rotating roller 41 to decelerate at the first deceleration acceleration when the rotating roller 41 has rotated 3 / 4 revolutions, so that the rotating roller 41 completes the winding of the paper core and rotates the pasted overlapping section on the paper core to the fixed position where the fixed component 5 is located, and the rotation speed is 0.

[0082] In practical applications, the first control element includes a second control element. When the paper blank is connected to the rotating roller 41, i.e., when the adsorption component 42 adsorbs the paper blank onto the outer circumferential surface of the rotating roller 41, the second control element controls the rotating roller 41 to wind at a relatively fast first winding speed. This first winding speed is the speed at which the servo motor drives the rotating roller 41 to rotate, preset by technicians according to actual conditions. When the encoder detects that the rotating roller 41 has rotated 3 / 4 of a revolution, the third control element controls the rotating roller 41 to decelerate with a first deceleration acceleration, also preset by technicians according to actual conditions. This ensures that the end of the paper blank, under the influence of the centrifugal force generated by the rotation of the rotating roller 41, remains adhered to the outer circumferential surface of the rotating roller 41 for winding until it overlaps with the beginning of the paper blank, forming a paper core. Then, to better fix the flat strip to the paper core, the rotating roller 41 continues to decelerate with the paper core, ensuring that the newly bonded paper core does not separate due to excessive centrifugal force, thus improving bonding quality. When the pasting overlap section rotates to the fixed position of the fixing component 5, the third control element controls the servo motor to stop rotating, the rotation speed is 0, and the rotating roller 41 is stationary, so that the fixing component 5 can fix the flat strip material on the pasting overlap section, improve the degree of automation of winding and enhance the winding quality.

[0083] In some preferred embodiments, the controller further includes:

[0084] The second acquisition module is used to acquire the real-time position of the adsorption component 42 after the flat strip is wound up;

[0085] The fifth control module is used to adjust the rotation direction of the rotating roller 41 according to the real-time position and the initial position, so that the adsorption component 42 is reset to the starting point of rotation.

[0086] In practical applications, the controller further includes a second acquisition module and a fifth control module. The second acquisition module can be a sensor to acquire the real-time position of the adsorption component 42 after the flat strip is wound up. The fifth control module adjusts the rotation direction of the rotating roller 41 based on the real-time position and the initial position of the adsorption component 42, so that the adsorption component 42 returns to the starting point of rotation for the next round of paper blank adsorption and winding. The starting point of rotation is the initial position of the adsorption component 42. The fifth control module specifically includes:

[0087] First processing element: used to calculate the rotation angle of adsorption component 42 based on real-time position and initial position;

[0088] The fourth control element is used to adjust the rotation direction of the rotating roller 41 according to the rotation angle. When the rotation angle is greater than 180°, the rotation direction of the rotating roller 41 is kept unchanged, so that the adsorption component 42 is reset to the starting point of rotation. When the rotation angle is less than or equal to 180°, the rotating roller 41 is adjusted to rotate in the opposite direction of the original rotation direction, so that the adsorption component 42 is reset to the starting point of rotation.

[0089] The rotation angle refers to the angle between the real-time position of the adsorption component 42 after the flat strip is wound up and the initial position. The distance between the real-time position and the initial position on the rotating roller 41 can be calculated by using the real-time position and the initial position. Then, the rotation angle between the real-time position and the initial position can be calculated according to the arc length angle formula (existing technology).

[0090] By adjusting in the above way, the adsorption component 42 returns to its initial position before the next winding begins, which facilitates the adsorption of the paper blank.

[0091] As can be seen from the above, the automatic winding system provided in this application, by setting a fixing component 5, a paper winding component 2, a tape winding component 3, and a winding component 4 on the automatic winding system, can realize the function of winding paper cores and flat strip materials on the same equipment, saving the time of manually transferring paper cores and manually feeding paper cores, and improving winding efficiency. Among them, the winding component 4 includes a rotating roller 41. The first driving component 43 drives the rotating roller 41 to rotate to realize the function of winding paper blanks and flat strip materials. The second driving component 44 drives the rotating roller 41 to extend and retract along the axial direction of the rotating roller 41, so that the rotating roller 41 automatically unloads the paper core and flat strip materials after winding is completed, without the need for manual unloading, thus improving production efficiency. The fixing component 5 is used to fix the free end of the flat strip material to the paper core, so that the flat strip material is better wound on the paper core through the fixing point. Moreover, by setting the fixing component 5, the manpower of winding the flat strip material on the paper core can be saved, improving the automation level of the winding equipment and increasing production efficiency. The automatic winding system also includes a controller, which includes a first control module. After the paper blank is wound into a paper core, the first control module controls the rotating roller 41 to rotate, rotating the adhesive overlap section on the paper core to the fixed position of the fixing component 5. This allows the fixing component 5 to fix the free end of the flat strip to the adhesive overlap section of the paper core. Since the paper blank has just been wound into a paper core, the adhesive on the adhesive overlap section has not yet fully solidified. If the flat strip is fixed to other parts of the paper core, the tension generated by the flat strip during winding may pull the wound paper core apart from the paper blank. To avoid this problem, the fixing component 5 fixes the free end of the flat strip to the adhesive overlap section of the paper core. This not only fixes the flat strip to the paper core for winding but also further reinforces the adhesive overlap section of the paper core, improving the winding quality. Therefore, the automatic winding system proposed in this application can realize the winding of paper cores and flat strips on the same equipment, eliminating the need for manual transfer and installation of paper cores, thus improving the automation and efficiency of winding.

[0092] This application provides an automatic winding method for controlling an automatic winding system to perform winding. The automatic winding system includes a fixing component 5, a paper roll component 2, a tape roll component 3, and a winding component 4 for winding the paper blank released from the paper roll component 2 and the flat strip material released from the tape roll component 3.

[0093] The winding assembly 4 includes a rotating roller 41, a first driving component 43 for driving the rotating roller 41 to rotate, and a second driving component 44 for driving the rotating roller 41 to extend and retract along the axial direction of the rotating roller 41.

[0094] The fixing component 5 is used to fix the free end of the flat strip to the paper core formed by winding the paper blank;

[0095] The method includes the following steps: after the paper blank is wound to form a paper core, the rotating roller 41 is controlled to rotate, and the bonding overlap section on the paper core is rotated to the fixed position of the fixing component 5, and the fixing component 5 is controlled to fix the free end of the flat strip material on the bonding overlap section.

[0096] In specific applications, this automatic winding method controls the automatic winding system. After the paper blank is wound to form a paper core, the rotating roller 41 continues to rotate until the overlapping section on the paper core corresponds to the fixing station where the fixing component 5 is located. This facilitates the fixing station to fix the flat strip at the overlapping section of the paper core. The overlapping section refers to the part where the ends of the paper blank overlap. The fixing component 5 fixes the flat strip to the overlapping section of the paper core. The pin passes through the flat strip and the two layers of paper blank to fix the flat strip to the paper core. This strengthens the connection between the ends of the paper core. Furthermore, since the bonding time at the ends of the paper core is relatively short and the glue has not fully cured, if the flat strip is fixed to other parts of the paper core, it will generate tension along the winding direction during the winding process, pulling the paper core apart into paper blanks and affecting the winding process. Therefore, to improve the winding quality, the flat strip can be fixed to the overlapping section.

[0097] In some specific implementations, the method further includes the following steps:

[0098] After the flat strip is wound up, the second drive unit 44 drives the rotating roller 41 to retract and unload the paper core and the flat strip wound on the paper core.

[0099] In practical applications, after the flat strip is wound up, the second drive component 44 drives the rotating roller 41 to shrink and unload the paper core and flat strip. This eliminates the need for manual disassembly and operation of the wound material, thereby improving the automation level of the winding equipment and saving human resources.

[0100] In some preferred embodiments, the paper roll assembly 2 includes a paper feed tray for discharging the paper blank, a cutter component for cutting the paper blank, and an adhesive dispensing component for applying adhesive to the end of the cut paper blank.

[0101] The method further includes the steps of: when the length of the paper blank released is longer than the circumference of the outer circumference surface of the rotating roller 41 and can be wound around the rotating roller 41 to form a paper core, controlling the cutting component to cut the paper blank, and simultaneously controlling the glue dispensing component to apply glue to the cut end of the paper blank.

[0102] When the first end of the paper blank is adsorbed onto the rotating roller 41, the rotating roller 41 is controlled to rotate, so that the paper blank is wound on the rotating roller 41, and the end of the paper blank adheres to the first end to form a paper core.

[0103] When the first end of the paper blank is adsorbed onto the rotating roller 41, the rotating roller 41 is controlled to rotate, so that the paper blank is wound up on the rotating roller 41, and the end of the paper blank adheres to the first end to form a paper core. The steps include:

[0104] The number of rotations of the rotating roller 41 is obtained in real time, with the initial position of the adsorption component 42 on the rotating roller 41 as the starting point of rotation.

[0105] Adjust the rotation speed of the rotating roller 41 according to the number of rotations of the rotating roller 41. When the rotating roller 41 finishes winding the paper core and rotates the overlapping section on the paper core to the fixed position where the fixed component 5 is located, the rotation speed is 0, so as to connect the flat strip material for winding.

[0106] Among them, such as Figure 3 As shown, in practical applications, by controlling the rotation speed of the rotating roller 41, the paper blank is adsorbed onto the outer circumferential surface of the rotating roller 41 and can be smoothly wound to form a paper core, which is then connected to the flat strip for winding. An encoder can be set to obtain the number of rotations. Specifically, the encoder is connected to the rotating shaft in the rotating roller 41 via a transmission sprocket to obtain the number of rotations of the rotating shaft, and thus the number of rotations of the rotating roller 41 can be calculated. Furthermore, the rotation speed of the rotating roller 41 can be adjusted according to the number of rotations of the rotating roller 41. When the paper blank is just adsorbed onto the outer circumferential surface of the rotating roller 41 by the adsorption component 42, the rotating roller 41 is controlled to rotate at a faster speed to speed up the winding efficiency. After the paper blank is wound to a certain extent, the rotation speed is reduced to avoid the centrifugal force on the paper blank being too large due to the excessive rotation speed of the rotating roller 41, making it difficult to adhere to the outer circumferential surface of the rotating roller 41 for winding. The rotating roller 41 gradually reduces its rotation speed. When the end of the paper blank overlaps and contacts the beginning, the pressure roller in the paper winding assembly 2 approaches the rotating roller 41 to press the end of the paper blank firmly against the beginning to form the paper core. After the paper core is formed from the paper blank, flat strips are connected to the paper core for winding. In order to facilitate the free end of the flat strip to be fixed to the paper core, when the overlapping section of the paper core rotates to the fixed position of the fixing component 5, the rotation speed of the rotating roller 41 can be reduced to 0. After the fixing component 5 fixes the flat strip to the paper core, the rotation speed of the rotating roller 41 is increased to wind up the flat strip.

[0107] In some specific embodiments, the rotation speed of the rotating roller 41 is adjusted according to the number of rotations of the rotating roller 41, so that when the rotating roller 41 finishes winding the paper core and rotates the overlapping section on the paper core to the fixed position where the fixed component 5 is located, the rotation speed is 0, and the winding of the flat strip material includes the following steps:

[0108] When the paper blank is connected to the rotating roller 41, the rotating roller 41 is controlled to wind up at a first winding speed;

[0109] When the rotating roller 41 rotates to 3 / 4 revolutions, the rotating roller 41 is controlled to decelerate with the first deceleration acceleration, so that the rotating roller 41 completes the winding of the paper core and rotates the pasted overlapping section on the paper core to the fixed position where the fixed component 5 is located, the rotation speed is 0.

[0110] In practical applications, when the paper blank is connected to the rotating roller 41, that is, when the adsorption component 42 adsorbs the paper blank onto the outer circumferential surface of the rotating roller 41, the rotating roller 41 is controlled to wind up at a relatively fast first winding speed. The first winding speed is the speed at which the rotating roller 41 is driven by the servo motor and is preset by the technician according to the actual situation. When the encoder detects that the rotating roller 41 has rotated to 3 / 4 revolution, the rotating roller 41 is controlled to decelerate at a first deceleration acceleration. The first deceleration acceleration is also preset by the technician according to the actual situation, so that the end of the paper blank can still adhere to the outer circumferential surface of the rotating roller 41 under the influence of the centrifugal force generated by the rotation of the rotating roller 41 and be wound up until it coincides with the beginning of the paper blank, and the beginning and end are bonded to form a paper core. Then, in order to better fix the flat strip material to the paper core, the rotating roller 41 continues to decelerate with the paper core, which can ensure that the paper core formed by the bonding together will not separate due to excessive centrifugal force, thus improving the bonding quality. When the overlapping section rotates to the fixed position of the fixing component 5, the servo motor stops rotating and the rotation speed is 0. The rotating roller 41 stops, which makes it easier for the fixing component 5 to fix the flat strip on the overlapping section, improves the automation of winding and enhances the winding quality.

[0111] In some preferred embodiments, the method further includes the step of:

[0112] After the flat strip is wound up, the real-time position of the adsorption component 42 is obtained;

[0113] Adjust the rotation direction of the rotating roller 41 according to the real-time position and the initial position, so that the adsorption component 42 is reset to the starting point of rotation.

[0114] In practical applications, the real-time position of the adsorption component 42 after the flat strip is wound is obtained. Then, based on the real-time position and the initial position of the adsorption component 42, the rotation direction of the rotating roller 41 is adjusted to reset the adsorption component 42 to the starting point of rotation for the next round of paper blank adsorption and winding. The starting point of rotation is the initial position of the adsorption component 42. Specifically, controlling the reset of the adsorption component 42 includes:

[0115] The rotation angle of the adsorption component 42 is calculated based on the real-time position and the initial position;

[0116] The rotation direction of the rotating roller 41 is adjusted according to the rotation angle. When the rotation angle is greater than 180°, the rotation direction of the rotating roller 41 is kept unchanged, so that the adsorption component 42 is reset to the starting point of rotation. When the rotation angle is less than or equal to 180°, the rotating roller 41 is adjusted to rotate in the opposite direction of the original rotation direction, so that the adsorption component 42 is reset to the starting point of rotation.

[0117] By adjusting in the above way, the adsorption component 42 returns to its initial position before the next winding begins, which facilitates the adsorption of the paper blank.

[0118] As can be seen from the above, the automatic winding method provided in this application, by setting a fixing component 5, a paper winding component 2, a tape winding component 3, and a winding component 4 on an automatic winding system, can realize the function of winding paper cores and flat strip materials on the same equipment, saving the time of manually transferring paper cores and manually feeding paper cores, and improving winding efficiency. Among them, the winding component 4 includes a rotating roller 41. A first driving component 43 drives the rotating roller 41 to rotate to realize the function of winding paper blanks and flat strip materials. A second driving component 44 drives the rotating roller 41 to extend and retract along the axial direction of the rotating roller 41, so that the rotating roller 41 automatically unloads the paper core and flat strip materials after winding is completed, without the need for manual unloading, thus improving production efficiency. The fixing component 5 is used to fix the free end of the flat strip material to the paper core, so that the flat strip material is better wound on the paper core through the fixing point. Moreover, by setting the fixing component 5, the manpower of winding the flat strip material on the paper core can be saved, improving the automation level of the winding equipment and increasing production efficiency. The automatic winding system also includes a controller, which includes a first control module. After the paper blank is wound into a paper core, the first control module controls the rotating roller 41 to rotate, rotating the adhesive overlap section on the paper core to the fixed position of the fixing component 5. This allows the fixing component 5 to fix the free end of the flat strip to the adhesive overlap section of the paper core. Since the paper blank has just been wound into a paper core, the adhesive on the adhesive overlap section has not yet fully solidified. If the flat strip is fixed to other parts of the paper core, the tension generated by the flat strip during winding may pull the wound paper core apart from the paper blank. To avoid this problem, the fixing component 5 fixes the free end of the flat strip to the adhesive overlap section of the paper core. This not only fixes the flat strip to the paper core for winding but also further reinforces the adhesive overlap section of the paper core, improving the winding quality. Therefore, the automatic winding system proposed in this application can realize the winding of paper cores and flat strips on the same equipment, eliminating the need for manual transfer and installation of paper cores, thus improving the automation and efficiency of winding.
