The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and are not to be construed as limitations of the present invention.

The following disclosure provides many different embodiments or examples of various structures for implementing the invention. In order to simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the invention. Furthermore, the present invention may repeat reference numbers and/or reference letters in different examples, such repetition being for purposes of simplicity and clarity and does not itself indicate a relationship between the various embodiments and/or arrangements discussed.

At present, flat sheet materials are usually wound on paper cores, and the winding equipment for forming paper cores and flat sheet strips is usually two different devices. In actual application, the paper blank is wound and formed on the paper core winding equipment. , the formed paper core is manually transferred and installed on the rotating roller that winds up the flat strip to wind up the flat strip. This method not only has complicated winding equipment, but also has a low degree of automation, which is not conducive to improving production efficiency. In order to solve this problem, this application provides an automatic winding system and an automatic winding method.

As shown in Figures 1 and 2, an automatic rewinding system includes a fixed component 5, a paper roll component 2, a tape take-up component 3, and a paper blank for rewinding the paper roll component 2 to unwind, and a tape take-up component 3 to unwind. Flat strip rewinding assembly 4;

The winding assembly 4 includes a rotating roller 41, a first driving component 43 that drives the rotating roller 41 to rotate, and a second driving component 44 that drives the rotating roller 41 to expand and contract along the axial direction of the rotating roller 41;

The fixing component 5 is used to fix the free end of the flat strip on the paper core formed by rolling the paper blank;

It also includes a controller, which at least includes:

The first control module, after the paper blank is rolled up to form a paper core, controls the rotation of the rotating roller 41, rotates the pasting overlap section on the paper core to the fixed station of the fixed component 5, and controls the fixed component 5 to move the flat strip The free end is fixed on the pasted overlapping section.

In specific applications, the automatic winding system can be used to wind up the paper core and the flat strip on the paper core. The automatic winding system centralizes the winding functions of the paper core and the flat strip. On the same equipment, the composition of the winding equipment is greatly simplified and the area occupied by the winding equipment is reduced. Compared with the existing technology, different equipment is used to wind up the paper core and flat strips respectively. The automatic winding system not only saves the labor and time costs of manual transfer and installation of paper cores, but also greatly saves the purchase of paper cores for some manufacturers whose main products are not paper cores. Operating costs of equipment or purchased paper cores.

Among them, the automatic rewinding system includes a fixed component 5, a paper roll component 2, a tape take-up component 3 and a rewinding component 4. Among them, the roll paper assembly 2 includes a cutter component and a glue dispensing component. The cutter component is used to cut the paper blank when the sensor detects that the length of the paper blank is enough to wrap around the rotating roller to form a paper core. The glue dispensing component is used to cut the paper blank. After the cutter component cuts the paper blank, glue is applied to the end of the cut paper blank so that the paper blank can be adhered and fixed to the first end of the paper blank when it is wound into a paper core. The winding assembly 3 also includes an adsorption component 42 arranged on the rotating roller 41, and a rubber roller arranged below the rotating roller 41. The rubber roller is connected to a driving device, and is driven closer or farther away by the driving device. The rotating roller 41, in which the rubber roller is close to the rotating roller 41 when the end of the paper base is about to stick to the first end, rolls the overlapping section of the paper base to make the paper core forming effect better. After the paper core is formed, The pressure roller is kept away from the rotating roller 41 to avoid interference with the winding of the flat strip. In a specific application, the paper roll assembly 2 is used to release the paper blank, and 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 holds the leading end of the paper blank. It is adsorbed on the outer circumferential surface of the rotating drum 41 to rotate and wind up to form a paper core. Among them, 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, the end of the paper blank covers the first end of the paper blank and overlaps and adheres. The cutter component in the paper roll assembly 2 will cut the paper blank, and the dispensing component provided on one side of the cutter component will dispense glue at the end of the paper blank to facilitate the paper blank to be wound on the outer circumferential surface of the rotating roller 41 After a week, the end of the paper blank can be adhered to the first end of the paper blank through the glue attached to it, and the adhesion part is the overlapping section.

In a specific application, the tape and reel assembly 3 is used to unwind the flat strip, which needs to be rolled up on the paper core to form a tape for subsequent packaging, transportation and sales. Since the glue dispensing component provided on the tape reel assembly 3 to glue the free end of the flat strip to adhere it to the paper core is not ideal, it is difficult to fix the free end of the flat strip to the paper core for winding. In the existing technology, the free end of the flat strip is usually manually wound around the paper core, and then the winding equipment is used for winding. This manual winding method has a low degree of automation and wastes a lot of time. It is not conducive to the improvement of production efficiency. The automatic winding equipment of the present application can improve the automation process of the winding process by setting the fixing component 5 to fix the free end of the flat strip. The specific fixing method is as follows: 3. When the free end of the flat strip is transported to the position of the rotating roller 41, the fixing component 5 provided on one side of the rotating roller 41 uses a nail pin to nail the free end of the flat strip to the paper core to achieve flattening. The fixation of the flat strip and the paper core facilitates the winding of the flat strip onto the paper core.

In a specific application, the rotating roller 41 is also connected to a first driving component 43 and a second driving component 44. The first driving component 43 can be a servo motor, and the servo motor passes through a rotating shaft through the axis of the rotating roller 41. center, driving the rotating roller 41 to rotate; the second driving component 44 can be a servo electric cylinder, the rotating roller 41 can be set on the slide rail through the mounting base, the servo electric cylinder is connected to the mounting base, and the driving mounting base drives the rotating roller 41 Expand and contract along the axial direction. When the rotating roller 41 extends, the paper blank and the flat strip material are rolled up. When the rotating roller 41 retracts, the material wrapped around the rotating roller 41 can be unloaded. In order to reduce the To reduce the floor space of the automatic winding system, a cavity for accommodating the rotating roller 41 can be provided inside the frame 1 of the automatic winding system. When the rotating roller 41 retracts, it can be retracted into the cavity inside the frame 1. It can not only easily unload the rolled materials, but also prevent the rotating roller 41 from occupying extra space due to the need to expand and contract. Among them, in order to better unload the material, the automatic winding system also includes a unloading assembly 6. The unloading assembly 6 is arranged directly below the rotating roller 41 and has a U-shaped clamping opening 61. After the material winding is completed, the unloading assembly 6 The material assembly 6 is close to the rotating roller 41, and the material (paper core and flat strip rolled on the paper core) is inserted into the U-shaped clamp 61 and clamped. The rotating roller 41 retracts, and the unloading assembly 6 removes the material. It is unloaded and transported to the unloading assembly for discharging. No manual assistance is required, and the degree of automation of the equipment is greatly improved.

Among them, in specific applications, the automatic winding system also includes a controller, where the controller can be a PLC device. The controller at least includes a first control module. The first control module controls the rotation after the paper base is rolled up to form a paper core. The roller 41 continues to rotate until the overlapping section of the paper core corresponds to the fixed station where the fixing assembly 5 is located, thereby facilitating the fixing assembly 5 to fix the flat strip to the overlapping section of the paper core. Among them, the pasting overlap section actually refers to the location of the overlapped portion of the paper blank end to end. The fixing component 5 fixes the flat strip to the pasting overlap section of the paper core. The nail needle passes through the flat strip and the two layers of paper blanks to secure the flat strip. The piece of strip is fixed on the paper core (the fixing component 5 is a conventional component used for fixation. The nail pin can be fixed on the object in a telescopic manner, and its structure will not be described in detail here). On the one hand, the first and last sides of the paper core can be fixed. On the other hand, the first and last ends of the paper core are bonded for a short time, and the glue may not be completely solidified. If the flat strip is fixed to other parts of the paper core, the flat strip will During the rolling process, tension will be generated along the winding direction, which will pull and separate the paper core into paper blanks, affecting the winding process. Therefore, in order to improve the winding quality, the flat strips can be fixed in the overlapping section.

Compared with the flat strip rewinding process in the prior art, this application integrates the winding functions of the paper core and the flat strip on the same rewinding equipment, saving the manpower and time costs of manpower transfer and installation of the paper core. , and a fixing component 5 is set on the automatic winding system so that the fixing component 5 can fix the flat strip on the paper core and wind it up, without the need for manual auxiliary winding, which improves the production automation performance. Furthermore, the fixing component 5 fixes the flat strip When rewinding the strip, choose to fix the flat strip to the overlapping section of the paper core to prevent the flat strip from tearing the paper core during rewinding and improve production quality. Therefore, the automatic rewinding system provided by this application can The winding of paper cores and flat strips is centralized on the same equipment, eliminating the need for manual transfer and installation of paper cores, which has the beneficial effect of improving winding automation and winding efficiency.

In some preferred embodiments, the roll paper assembly 2 includes a paper release tray for releasing the paper blank, a cutter component for cutting the paper blank, and a glue dispensing component for applying glue to the end of the cut paper blank;

The controller also includes a third control module: used to control the cutter component to cut the paper blank when the length of the paper blank is longer than the circumference of the outer circumferential surface of the rotating roller 41 and can be wound around the rotating roller 41 to form a paper core. , and simultaneously control the dispensing component to apply glue to the end of the cut paper blank;

The fourth control module: used to control the rotation of the rotating roller 41 when the first end of the paper blank is adsorbed on the rotating roller 41, so that the paper blank is rolled up on the rotating roller 41, and the end of the paper blank is adhered to the first end to form paper core;

The fourth control module includes:

The first acquisition element: takes the initial position of the adsorption component 42 on the rotating roller 41 as the starting point of rotation, and acquires the number of rotations of the rotating roller 41 in real time;

Therefore, in order to make the cutting and gluing operation more convenient, the cutter component and the dispensing component can be They are arranged side by side, and the dispensing component is closer to the rotating roller than the cutter component, which facilitates the gluing component to apply glue to the end of the cut paper blank after the paper blank is cut.

The paper roll assembly 2 is provided on the automatic winding system to cooperate with the rotating roller 41 to automatically wind the paper blank into a paper core, which can save the time of manually loading the paper core on the rotating roller 41. Compared with the winding equipment in the prior art, the automatic winding system proposed in this application can pass the paper blank through the steps of conveying, cutting, gluing, etc., and then adsorbing it to the rotating roller through the adsorption component 42 on the rotating roller 41 The outer circumferential surface of the drum 41 is rolled up, and the paper blank is only rolled up once, so that the first and last ends of the paper blank can be adhered by glue to automatically form a paper core, which improves the winding efficiency and greatly saves money. labor costs in the production process.

After the paper blank is rolled up to a certain extent, the rotation speed will be reduced to prevent the rotating roller 41 from rotating too fast and causing the paper blank to be subject to a large centrifugal force, making it difficult to adhere to the rotating The outer circumferential surface of the roller 41 is rolled up, and the rotating roller 41 slowly reduces the rotation speed. When the end of the paper base overlaps with the first end, the rubber roller in the paper roll assembly 2 is close to the rotating roller 41, and the paper is rolled up. The end and first end of the blank are pressed firmly to form a paper core. After the paper core is formed from the paper base, the flat strip will be connected to the paper core for winding. In order to facilitate the fixation of the free end of the flat strip with the paper core, the overlapping section of the paper core is rotated to the fixed station of the fixing assembly 5 At this time, the rotation speed of the rotating roller 41 can be reduced to 0. After the fixing assembly 5 fixes the flat strip on the paper core, the first control element then controls the rotating roller 41 to increase the rotation speed and wind up the flat strip. material.

Large and separated, improve bonding quality. When the pasting and overlapping section rotates to the fixed station of the fixing component 5, the third control element controls the servo motor to stop rotating at a speed of 0, and the rotating roller 41 is stationary, which facilitates the fixing component 5 to fix the flat strip at the pasting and overlapping position.

The paper blank has just been rolled into the paper core, and the glue in the overlapping section has not yet completely solidified. If Fix the flat strip to other parts of the paper core. The tensile force generated by the flat strip during winding may pull and separate the rolled paper core into paper blanks. In order to avoid this problem, the fixing component 5 will The free end of the strip is fixed on the overlapping section of the paper core, which can not only fix the flat strip on the paper core for winding, but also further reinforce the overlapping section of the paper core to improve the winding quality.

Among them, the pasting overlap section actually refers to the location of the overlapped portion of the paper blank end to end. The fixing component 5 fixes the flat strip to the pasting overlap section of the paper core. The nail needle passes through the flat strip and the two layers of paper blanks to secure the flat strip. The flat strip is fixed on the paper core. On the one hand, the connection between the first and last ends of the paper core can be reinforced. On the other hand, the first and last ends of the paper core have a short adhesion time and the glue cannot be completely solidified. If the flat strip is fixed on In other parts of the paper core, the flat strip will generate tension along the winding direction during the winding process, pulling and separating the paper core into paper blanks, which affects the winding process. Therefore, in order to improve the winding quality, the flat strip can be The material is fixed on the pasted overlapping section.

In some specific implementations, the method further includes the steps of:

When the leading end of the paper blank is adsorbed on the rotating roller 41, the rotating roller 41 is controlled to rotate so that the paper blank is rolled up on the rotating roller 41, and the end and the first end of the paper blank are adhered to form a paper core;

When the leading end of the paper blank is adsorbed on the rotating roller 41, the rotating roller 41 is controlled to rotate so that the paper blank is rolled up on the rotating roller 41. The steps of adhering the end and the leading end of the paper blank to form a paper core include:

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 obtained in real time;

Among them, as shown in Figure 3, in practical applications, by controlling the rotation speed of the rotating roller 41, the paper blank can be smoothly rolled up to form a paper core after being adsorbed on the outer circumferential surface of the rotating roller 41, and then connected to the flat sheets. The strip is rolled up. An encoder can be set up to obtain the number of rotations. Specifically, the encoder is connected to the rotation shaft in the rotating roller 41 through the transmission sprocket to obtain the number of rotations of the rotating shaft, and then the rotation circle of the rotating roller 41 can be calculated. number. 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 on the outer circumferential surface of the rotating roller 41 by the adsorbing member 42, the rotating roller 41 is controlled to rotate faster. Speed rotation will speed up the winding efficiency. After the paper blank is rolled up to a certain extent, the rotation speed will be reduced to prevent the rotating roller 41 from rotating too fast. The centrifugal force on the paper blank will be large and it will be difficult to adhere to the rotating roller 41.

The first winding speed is the speed at which the servo motor drives the rotating roller 41 to rotate. It is preset by the technician according to the actual situation. When the encoder detects that the rotating roller 41 rotates to 3/4 During the circle, 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 is under the influence of the centrifugal force generated by the rotation of the rotating roller 41. It can still fit on the outer circumferential surface of the rotating roller 41 and be rolled up until it coincides with the first end of the paper blank, and the end and end are adhered to form a paper core. Then, in order to better fix the flat strip material on the paper core, the rotating roller The drum 41 is still running at a reduced speed with the paper core, which can ensure that the paper cores just joined together will not separate due to excessive centrifugal force, thereby improving the bonding quality. When the pasting overlapping section rotates to the fixed station of the fixing component 5, the servo motor is controlled to stop rotating, the rotation speed is 0, and the rotating roller 41 is stationary, which facilitates the fixing component 5 to fix the flat strip material on the pasting overlapping section.

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

Among them, in practical applications, the real-time position of the adsorption component 42 after the flat strip is rolled up is obtained, and then the rotation direction of the rotating roller 41 is adjusted according to the real-time position and the initial position of the adsorption component 42 to reset the adsorption component 42 to Rotate the starting point and perform the next round of paper base adsorption and winding. The starting point of rotation is the initial position of the adsorption member 42 . Among them, controlling the reset of the adsorption component 42 specifically includes:
