[0002] In the 1990s, papermaking machines experienced unprecedented rapid development, with the continuous emergence of new concepts, technologies, and equipment. Design speeds reached as high as 2,500 m / min. Simultaneously, post-processing technologies such as coating machines and supercalendering also advanced rapidly, with the design speed of coating machines steadily increasing. Subsequently, reeling technology also saw new developments, with the emergence of first, second, and third generations of reels. These reels, employing different design concepts, mechanisms, and control methods, led to significant advancements in industrial production. The third generation of reels currently in use, also known as modern reels, emerged in the mid-to-late 1990s. They are successfully used for winding and rewinding on a variety of modern high-speed papermaking machines, including newsprint, supercalendered paper, low-weight coated paper, ultra-low-weight coated paper, and coated and uncoated fine paper, as well as on modern post-processing lines. Reels offer excellent operating performance and reliable operation. It has outstanding advantages in producing large-diameter paper rolls, reducing paper loss, improving production efficiency, improving paper roll quality, optimizing paper roll structure, and protecting paper surface properties.

[0003] The paper winder is the most important part of the coating machine. It relies on the weight of the paper roller and the friction of the cold cylinder to drive the paper off the winder to be evenly wound to make the paper more uniform to meet the needs of different papers.

[0004] The paper winding precision of the paper winding machine currently in use is relatively poor, and the paper is easily wrinkled during the winding process. Summary of the Invention

[0045] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0046] It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and the accompanying drawings are used to distinguish similar items and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, such that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions.

[0047] Next, a paper reel control method according to an embodiment of the present invention will be described.

[0048] like Figure 1 The paper winding machine of the embodiment of the present invention includes a first paper winding roller 110 and a second paper winding roller 120. The first paper winding roller 110 and the second paper winding roller both extend in the horizontal direction and are spaced apart in the longitudinal direction. The first paper winding roller 110 and the second paper winding roller 120 are used to wind the paper 130. The first paper winding roller 110 and the second paper winding roller 120 can cooperate with each other to tighten the paper 130.

[0049] A table 200 is set under the paper 130. The table 200 can be a printing table 200, a coating table 200, a printer table 200, etc. The first paper roller 110 and the second paper roller 120 roll the paper 130 to move the product (such as battery cells, etc.) carried on the paper 130, thereby realizing loading or unloading.

[0050] like Figure 2 As shown, the paper reel control method according to the embodiment of the present invention includes:

[0051] S1, controlling the first paper roll 110 and the second paper roll 120 to rotate along a predetermined direction.

[0052] S2 , controlling the rotation mode of the first paper roller 110 to be one of the first mode and the second mode, and controlling the rotation mode of the second paper roller 120 to be the other of the first mode and the second mode.

[0053] The first mode is rotation based on a predetermined angle, and the second mode is rotation based on a predetermined torque.

[0054] The predetermined direction may be clockwise or counterclockwise. For example, the controller drives the first paper roller 110 to rotate in the clockwise direction via the first motor, and drives the second paper roller 120 to rotate in the clockwise direction via the second motor.

[0055] The first mode may also be referred to as a periodic position mode, in which rotation is based on a predetermined angle. A predetermined angle rotation instruction may be input to the first or second paper roller 110 or 120, and the first or second paper roller in the first mode rotates the predetermined angle based on the instruction.

[0056] For example, you can select the cyclic position mode in the EtherCAT drive. Configure DRIVE_PROFILE to position-based mode 1, ATYPE=66, execute the bus initialization routine, set the axis's operating parameters such as units and speed, and use motion commands to send pulses to the motor to control the axis's operation.

[0057] The second mode may also be referred to as a cyclic torque mode, in which rotation is performed based on a predetermined torque. A predetermined torque rotation instruction may be input to the first or second paper reel 110 or 120, and the first or second paper reel in the second mode rotates based on the instruction.

[0058] The torque calculation formula is: T = 9550P / n, where p is power in kW, n is speed in rpm (r / min), and torque is in Nm. The denominator is the rated speed n in r / min. A predetermined voltage or current is input to the motor driving the first or second paper roller, giving the motor a predetermined power, thereby producing a predetermined torque.

[0059] For example, you can select the periodic torque mode in the EtherCAT drive. Configure DRIVE_PROFILE to mode 30 with torque and ATYPE=67. After executing the bus initialization procedure, send DAC commands in the online command bar to control the motor. When DAC=30, the current drive torque is 0.03, and a DAC value of 1000 represents 100% torque. To increase the operating speed, increase the DAC value. If the DAC value is too small, the motor will not be able to overcome friction and will not rotate.

[0060] By controlling the first and second paper rollers 110 and 120 to rotate in a predetermined direction, the paper 130 wound by the first and second paper rollers 110 and 120 can be moved, thereby driving the product carried by the paper 130 to move.

[0061] In the first mode, the first paper roller 110 or the second paper roller 120 can rotate at a precise angle and achieve accurate positioning, thereby accurately moving the paper 130 and further accurately moving the product on the paper 130 to a predetermined location.

[0062] The second paper winding roller 120 or the first paper winding roller 110 in the second mode can rotate with precise torque, which can maintain constant tension on the paper 130 and avoid damage to the paper 130 or reduction in quality of the paper 130 due to uneven force during the winding process.

[0063] The first paper winding roller 110 of the first mode and the second paper winding roller 120 of the second mode, or the second paper winding roller 120 of the first mode and the first paper winding roller 110 of the second mode, cooperate with each other to accurately move the paper 130 and maintain a constant tension on the paper 130 to prevent the paper 130 from being wrinkled or damaged.

[0064] In some embodiments of the present invention, the predetermined direction includes a first direction and a second direction, the first direction and the second direction being opposite. When the predetermined direction is the first direction, the rotation mode of the first paper roller 110 is the first mode, and the rotation mode of the second paper roller 120 is the second mode. When the predetermined direction is the second direction, the rotation mode of the first paper roller 110 is the second mode, and the rotation mode of the second paper roller 120 is the first mode.

[0065] For example, the first direction is clockwise or forward, and the second direction is counterclockwise or reverse; or, the first direction is counterclockwise or reverse, and the second direction is clockwise or forward.

[0066] like Figure 1 As shown, when the first paper roller 110 and the second paper roller 120 rotate counterclockwise, the product can be driven to move to the left through the paper 130, and the rotation mode of the first paper roller 110 is the first mode, and the rotation mode of the second paper roller 120 is the second mode. When the first paper roller 110 and the second paper roller 120 rotate clockwise, the product can be driven to move to the right through the paper 130, and the rotation mode of the first paper roller 110 is the second mode, and the rotation mode of the second paper roller 120 is the first mode.

[0067] The first paper roller 110 and the second paper roller 120 can rotate in sequence. The first paper roller 110 or the second paper roller 120 in the second mode can be controlled to rotate first. When a predetermined torque is reached, the second paper roller 120 or the first paper roller 110 in the first mode rotates again, so as to accurately maintain the tension of the paper 130 and avoid wrinkles.

[0068] During the switching process between the first direction and the second direction, the rotation modes of the first paper roller 110 and the second paper roller 120 are switched synchronously, so that the first paper roller 110 or the second paper roller 120 in the second mode can always rotate first and put the paper 130 in a tensioned state.

[0069] Furthermore, the paper reel control method further includes: controlling the first paper reel roller 110 and the second paper reel roller 120 to rotate alternately in the first direction and the second direction.

[0070] The first paper reel 110 and the second paper reel 120 automatically rotate along the first direction and the second direction, so that the products transported by the paper 130 can be continuously loaded and unloaded efficiently.

[0071] By alternating between periodic position mode and periodic torque mode, the coordinated control of the first motor and the second motor in the paper winder is effectively solved. By utilizing a periodic position mode similar to a positioner, the paper winding accuracy during movement is increased while the motor loss is fully reduced, thereby increasing the motor's service life.

[0072] Furthermore, before controlling the first paper winding roller 110 and the second paper winding roller 120 to rotate along a predetermined direction, the paper winding machine control method also includes: controlling the first paper winding roller 110 and the second paper winding roller 120 to reset to the origin, and using the reset position as the starting position for the rotation of the first paper winding roller 110 or the second paper winding roller 120.

[0073] By resetting, the starting position of the first paper roller 110 or the second paper roller 120 in the first mode can be stabilized, the rotation angle can be reset to zero, the accuracy of moving the paper 130 can be increased, and a basis can be provided for subsequent return from the end position to the starting position.

[0074] Furthermore, based on the actual position of the first paper winding roller 110 or the second paper winding roller 120 after the rotation is completed in the first mode, the end position of the first paper winding roller 110 and the second paper winding roller 120 is determined, and the first paper winding roller 110 and the second paper winding roller 120 are controlled to rotate back and forth between the end position and the starting position.

[0075] The position where the first or second paper roller 110, 120 actually stops after rotating by a predetermined angle in the first mode is the end position. For example, the position where the first or second paper roller 110, 120 actually stops after rotating by 540 degrees (1.5 turns) in the first mode is the end position.

[0076] The first paper winding roller 110 or the second paper winding roller 120 rotated according to the first mode accurately locates the end position, thereby improving the accuracy of the movement of the paper 130.

[0077] The first paper reel 110 and the second paper reel 120 reciprocate between an end position and a start position, thereby achieving accurate loading and unloading of products transported by the paper 130 .

[0078] In some embodiments of the present invention, a first number of first pulses is input to the first motor to control the first paper roller 110 to rotate at a first angle, and a second number of second pulses is input to the second motor to control the second paper roller 120 to rotate at a second angle, wherein the first motor is used to drive the first paper roller 110 to rotate, and the second motor is used to drive the second paper roller 120 to rotate, the frequency of the first pulse corresponds to the rotation speed of the first paper roller 110 driven by the first motor, and the frequency of the second pulse corresponds to the rotation speed of the second paper roller 120 driven by the second motor.

[0079] For example, the frequency of the first pulse and the frequency of the second pulse are both 5000 per second, corresponding to the rotation speed of the first paper roller 110 and the second paper roller 120, 15000 pulses are input to the first motor, and the first motor rotates for 3 seconds, then the first motor can drive the first paper roller 110 to rotate an angle at a certain speed, and 15000 pulses are input to the second motor, and the second motor rotates for 3 seconds, then the second motor can drive the second paper roller 120 to rotate an angle at a certain speed.

[0080] By inputting pulses to control the first and second paper reel rollers 110 and 120 to rotate by a predetermined angle, the rotation accuracy of the first and second paper reel rollers 110 and 120 is improved, and the positioning is more precise.

[0081] In some embodiments of the present invention, a first analog current or voltage is input to the first motor, thereby controlling the torque of the first paper roller 110 to be the first torque, and a second analog current or voltage is input to the second motor, thereby controlling the torque of the second paper roller 120 to be the second torque.

[0082] Among them, the first torque can be set according to the force that the first paper roller 110 can use to overcome the friction and rotate, the tension that the paper 130 can withstand, and the flatness required by the paper 130. The second torque can be set according to the force that the second paper roller 120 can use to overcome the friction and rotate, the tension that the paper 130 can withstand, and the flatness required by the paper 130.

[0083] A first analog current or voltage is input to the first motor, so that the first motor has a certain analog power, which is adapted to the force applied to the paper 130 during movement, so that the first torque of the first paper roller 110 remains stable.

[0084] The second analog current or voltage is input to the second motor, so that the first motor has a certain analog power, which is adapted to the force applied to the paper 130 during movement, so that the second torque of the second paper roller 120 remains stable.

[0085] In some embodiments of the present invention, the paper reel control method further includes:

[0086] The first paper reel 110 or the second paper reel 120 in the first mode stops rotating after reaching the end position; the second paper reel 120 or the first paper reel 110 in the second mode stops rotating after reaching a predetermined torque.

[0087] For example, first, the first paper roll 110 in the first mode rotates 3600 degrees (10 revolutions) to the end position and stops. Then, the second paper roll 120 in the second mode pulls the paper 130 until its torque reaches a predetermined torque and stops. Alternatively, first, the second paper roll 120 in the first mode rotates 3600 degrees (10 revolutions) to the end position and stops. Then, the first paper roll 110 in the second mode pulls the paper 130 until its torque reaches a predetermined torque and stops.

[0088] When the first paper roller 110 and the second paper roller 120 stop rotating, the tension of the paper 130 laid on the table 200 can be stabilized and flat, avoiding wrinkles. For example, when the paper 130 is laid on the coating table 200 and the battery cells are carried on the paper 130, the battery cells can be flattened, thereby improving the coating accuracy of the battery cells.

[0089] The paper reel control method of the present invention will be described below using specific examples.

[0090] Figure 3 FIG. 1 is a flow chart of a paper reel control method according to an embodiment of the present invention. Figure 3 As shown, after EtherCat is successfully initialized, the origin can be restored to reset the status of the first and second paper rollers 110 and 120. A periodic position mode is then set to define the starting positions of the first and second paper rollers 110 and 120. The first and second paper rollers 110 and 120 are then controlled to rotate in a first direction, i.e., the first paper roller 110 is set to the periodic position mode and the second paper roller 120 is set to the periodic torque mode. After the paper reel completes forward rotation, the end position is determined (i.e., the end position of the first paper roller 110 is determined). Subsequently, the first and second paper rollers 110 and 120 are controlled to rotate in a second direction, i.e., the first paper roller 110 is set to the periodic torque mode and the second paper roller 120 is set to the periodic position mode. Finally, the first and second paper rollers 120 are controlled to return from the end position to the starting position. A new round of control of the paper reel can then be performed.

[0091] In addition, if an abnormality occurs in the paper winder or control device during the above control process, it is necessary to restart the machine and start over from Ethercat initialization.

[0092] From the above description, it can be found that the paper roll motor in the embodiment of the present invention is not controlled in a single control mode, but through software, in conjunction with the change of driver parameters, while the equipment is running, different mode specifications are issued to the two drivers of the paper roll forward and paper roll reverse in the program. Through the alternating operation of the periodic position mode and the periodic torque mode, the coordinated control of the paper roll forward and reverse motors is effectively solved, and at the same time, the problem of the paper roll remote driver alarm caused by the sole use of the periodic torque mode in the early stage of debugging the equipment is solved; in addition, by utilizing a periodic position mode similar to a positioner, while increasing the paper roll accuracy during movement, the motor loss is fully reduced, thereby increasing the life of the paper roll motor and the paper roll.

[0093] Next, a paper reel control device 1000 according to an embodiment of the present invention will be described.

[0094] The paper reel control device includes a mode configuration module 1001, a first control module 1002, and a second control module 1003. Mode configuration module 1001 is used to configure the rotation mode of the first paper reel to be the first mode or the second mode, and also to configure the rotation mode of the second paper reel to be the second mode or the first mode. First control module 1002 is used to control the first paper reel to rotate in a predetermined direction, and to control the rotation mode of the first paper reel to be one of the first mode and the second mode. Second control module 1003 controls the second paper reel to rotate in a predetermined direction, and to control the rotation mode of the second paper reel to be the other of the first mode and the second mode. The first mode is rotation based on a predetermined angle, and the second mode is rotation based on a predetermined torque.

[0095] By cooperating with each other, the mode configuration module 1001 , the first control module 1002 , and the second control module 1003 , the paper can be moved accurately and the tension of the paper can be kept constant, thus preventing the paper from being wrinkled or damaged.
