Detailed Description
The present invention will be described below with reference to embodiments of the invention, but the following embodiments do not limit the invention according to the scope of claims. In addition, not all combinations of the features described in the embodiments are essential to the solution of the invention.
Fig. 1 shows one example of the structure of a winding system 200. The winding system 200 includes a transport unit 40, a winding unit 50, and a control device 100. The conveying unit 40 includes the web 11, a feed roller 44, a web motor M1, and a feed motor M2. The control device 100 includes a calculation unit 20 and a control unit 30. The winding unit 50 includes a winding motor M4 and a winding rotation shaft 52.
The web 11 is a roller-shaped object 10 before processing the object 10. The web 11 is fed to the object 10 at a speed corresponding to the operation of the web motor M1. The winding system 200 of this example includes 1 coil material 11, but may include a plurality of coil materials 11. The web 11 is connected to a web motor M1, driven by a web motor M1. Therefore, the object 10 is fed at a speed corresponding to the operation of the web motor M1.
The feed roller 44 feeds the object 10 to the winding section 50 at a predetermined feed speed. The feed roller 44 of this example is connected to a feed motor M2, and is driven by a feed motor M2. Therefore, the feed roller 44 feeds the object 10 to the winding unit 50 at a speed corresponding to the operation of the feed motor M2.
The control unit 30 controls the conveyance speed and the winding speed of the object 10 to be constant without being affected by the winding angle of the winding rotation shaft 52. In the present specification, the conveyance speed of the object 10 refers to the speed of the object 10 fed to the feed roller 44. The winding speed of the object 10 is the speed of the object 10 wound from the feed roller 44. The control unit 30 controls the driving of at least one of the winding motor M4 and the conveyance motor Mf to fix the conveyance speed and the winding speed. The control unit 30 of this example controls the conveyance speed and the winding speed to be the same speed. In the present specification, the conveyance motor Mf is a motor that feeds the object 10 at a predetermined conveyance speed. For example, the conveying motor Mf is any one of a web motor M1 and a feed motor M2. On the other hand, the winding motor M4 operates to wind the object 10 at a predetermined winding speed.
The object 10 is not particularly limited as long as it can be wound around the winding rotation shaft 52. In one example, the object 10 has a belt-like shape such as paper or film. For example, the object 10 is an electrode material of a lithium-ion two-dimensional battery. When a plurality of objects 10 are provided, the winding system 200 may wind the objects 10 to the winding rotation shaft 52 in an overlapping manner. The object 10 may be linear.
The winding rotation shaft 52 is driven by a winding motor M4 to wind the object 10 at a predetermined winding speed. The shape of the winding rotation shaft 52 in this example is not circular. When the winding rotation shaft 52 is not circular, the winding speed of the object 10 changes according to the rotation of the winding rotation shaft 52. The case where the winding rotation axis 52 is not circular means that the following cases may be included: the winding rotation axis 52 is circular, but the winding rotation axis 52 is finally non-circular due to the object 10 to be wound. The shape of the winding rotation shaft 52 is an outer peripheral shape of the winding rotation shaft 52 that comes into contact with the object 10 when the object 10 is wound. That is, the shape of the winding rotation shaft 52 is a cross-sectional shape of a plane perpendicular to the rotation shaft of the winding rotation shaft 52.
The calculation unit 20 calculates information on the shape of the winding rotation shaft 52. The calculation unit 20 may calculate information on the shape of the winding rotation shaft 52 after at least a part of the object 10 is wound around the winding rotation shaft 52. The information on the shape of the winding rotation shaft 52 may be obtained by controlling the driving of at least one of the winding motor and the conveyance motor Mf so that the conveyance speed and the winding speed are constant and are not affected by the winding angle of the winding rotation shaft 52. For example, the information on the shape of the winding rotation shaft 52 includes the conveyance amount of the object 10, the winding angle of the winding rotation shaft 52, the number of turns of the object 10, and the like.
The calculation unit 20 calculates information on the shape of the winding rotation shaft 52 after at least a part of the object 10 is wound around the winding rotation shaft 52. The information on the shape of the winding rotation shaft 52 after winding at least a part of the object 10 around the winding rotation shaft 52 can be calculated based on the winding angle of the winding rotation shaft 52 and the conveyance amount of the object 10. For example, the conveyance speed of the object 10 is calculated for each winding angle from the relationship between the winding angle of the winding rotation shaft 52 and the conveyance amount of the object 10. Therefore, the calculation unit 20 can calculate the control amount necessary to fix the conveyance speed and the winding speed.
In one example, the calculation section 20 calculates the outer periphery of the winding rotation shaft 52. For example, the calculation unit 20 calculates the amount of conveyance from an arbitrary winding angle to the next same winding angle. In other words, the calculation unit 20 calculates the conveyance amount of the winding rotation shaft 52 for one rotation. The calculation unit 20 may calculate the number of turns of the object 10 wound around the winding rotation shaft 52. In one example, the calculation unit 20 obtains information on the shape of the winding rotation axis 52 in advance for each number of turns of the object 10. Therefore, the control unit 30 can control the conveying unit 40 and the winding unit 50 according to the number of turns of the object 10.
Further, the calculation section 20 in one example calculates data on the shape of the winding rotation shaft 52 in advance. The calculation unit 20 calculates in advance a relationship between the winding angle of the winding rotation shaft 52 and the conveyance amount of the object 10. The relationship between the winding angle of the winding rotary shaft 52 and the conveying amount of the object 10 may be: a table showing a correspondence relationship between the winding angle of the winding rotary shaft 52 and the conveyance amount of the object 10. However, the winding angle of the winding rotation shaft 52 is not particularly limited as long as the correspondence relationship between the conveyance amount of the object 10 and the winding angle can be obtained.
The control unit 30 controls driving of at least one of the conveying unit 40 and the winding unit 50 based on the calculation result of the calculation unit 20. In one example, the control section 30 controls the driving of at least one of the winding motor M4 and the conveyance motor Mf based on the calculation result of the calculation section 20. Therefore, the control unit 30 controls the conveyance speed and the winding speed to be constant without being affected by the winding angle of the winding rotation shaft 52. When the transport motor Mf includes the web motor M1 and the feed motor M2, the controller 30 may control at least one of the web motor M1 and the feed motor M2.
The control unit 30 of this example controls the rotation speed of at least one of the winding motor M4 and the conveyance motor Mf for each winding angle of the winding rotation shaft 52. That is, when the winding rotation shaft 52 is not circular, the control unit 30 can control the rotation speed of at least one of the winding motor M4 and the conveyance motor Mf for each winding angle of the winding rotation shaft corresponding to the shape of the winding rotation shaft 52.
In one example, the control unit 30 controls the driving of at least one of the winding motor M4 and the conveyance motor Mf based on information acquired in advance by the calculation unit 20. The control unit 30 can make the driving of the winding system 200 uniform by performing control based on the information acquired in advance by the calculation unit 20. On the other hand, the control section 30 may control the driving of at least one of the winding motor M4 and the conveyance motor Mf based on the calculation result calculated by the calculation section 20 in the driving of the winding rotation shaft 52. In this case, the control unit 30 can control the operation of the winding rotary shaft 52 in real time for each product, and thus can more strictly control the conveyance speed and the winding speed to be constant. For example, the control unit 30 controls the next operation based on the calculation result of the calculation unit 20 corresponding to the previous operation of the winding rotation shaft 52.
Fig. 2 shows one example of a more specific structure of the winding system 200. The control device 100 is omitted from the figure. The winding system 200 of this example includes the feed rotary shaft 42, the length measuring roller 48, and the dancer roller 46. The configuration indicated by the reference numeral common to the winding system 200 of fig. 1 can perform the same operation as in fig. 1.
The length measuring roller 48 measures the conveyance amount of the object 10. The length measuring roller 48 of this example is disposed between the dancer 46 and the feed roller 44. However, the position of the length-measuring roller 48 may be between the web 11 and the feed roller 44, and is not limited to this example. In one example, the length measuring roller 48 is disposed between the web 11 and the dancer 46. Further, a measuring roller 48 may be provided before the feed roller 44.
The calculation unit 20 calculates information on the shape of the winding rotation shaft 52 based on the measurement result of the length measuring roller 48. The control unit 30 controls the driving of at least one of the winding motor M4 and the conveyance motor Mf based on the calculation result of the calculation unit 20. For example, the controller 30 controls the operation of at least 1 of the web motor M1, the feed motor M2, and the feed motor M5 with respect to the conveyance motor Mf.
The dancer 46 fixedly holds the tension of the object 10 in the winding. The dancer roller 46 of this example has a rotating shaft with rollers at both ends. A fixed torque is applied to the rotating shaft of the floating roller 46, and the floating roller 46 operates to maintain the torque applied to the rotating shaft. Therefore, the dancer 46 substantially constantly maintains the tension of the object 10. From the viewpoint of stability, it is preferable that the action of the dancer roller 46 be kept constant. The calculation unit 20 of this example can calculate information on the shape of the winding rotation shaft 52 based on the operation of the dancer roller 46.
For example, the calculation unit 20 calculates the conveyance amount of the object 10 based on the position of the dancer roller 46. The position of the dancer roller 46 may be the rotation angle of the rotation axis of the dancer roller 46 in addition to the position of the rotation axis of the dancer roller 46. If the rotation angle of the rotation axis of the dancer 46 is known, the amount of curvature of the object 10 adjusted by the dancer 46 can be known, and therefore the amount of conveyance of the object 10 can be accurately calculated. At this time, the control unit 30 also controls the driving of at least one of the winding motor M4 and the conveyance motor Mf based on the calculation result of the calculation unit 20. The structure of the dancer roller 46 is not limited to this example.
The feed rotary shaft 42 conveys the object 10 at a predetermined conveying speed. The feed rotation shaft 42 is connected to a feed motor M2, and is driven by a feed motor M5. Therefore, the feed rotary shaft 42 feeds the object 10 to the winding unit 50 at a speed corresponding to the operation of the feed motor M5. The winding system 200 of this example has 1 feeding rotary shaft 42, and may have a plurality of feeding rotary shafts 42.
Here, when the winding rotation shaft 52 is circular, the use of the dancer roller 46 can eliminate slack in the object 10 and fixedly control the tension of the object 10. On the other hand, when the winding rotation shaft 52 is not circular, the floating roller 46 fluctuates to accelerate or decelerate the conveyance speed of the object 10, and thus it is difficult to apply a constant tension to the object 10. However, since the control device 100 controls the driving of at least one of the winding motor M4 and the conveyance motor Mf for each winding angle of the winding rotation shaft 52, the tension of the object 10 can be fixed even if the winding rotation shaft 52 is not circular.
FIG. 3A shows the winding angle θ1The driving state of the winding rotation shaft 52. Fig. 3B shows a driving state of the winding rotary shaft 52 when the winding angle is 0 °. The winding angle θ of the winding rotation shaft 52 is 0 ° when parallel to the Y axis and is an angle when clockwise rotation is a positive direction of the winding angle.
Since the winding rotation axis 52 is not circular, the path length L of the object 10 changes according to the winding angle of the winding rotation axis 52. The path length L of the object 10 is a distance between the feeding contact point and the winding rotation axis contact point. For example, the winding angle θ1The path length of time is denoted L1The path length at a winding angle of 0 DEG is denoted by L0. Path length L of this example0Less than path length L1. Since the winding rotation shaft 52 is not circular, the winding speed varies depending on the winding angle of the winding rotation shaft 52. That is, in order to fix the conveying speed and the winding speed of the object 10, the winding system 200 must control at least one of the conveying speed and the winding speed according to the winding angle of the winding rotation shaft 52.
Fig. 4 is one example of a control block diagram of the winding system 200. The winding system 200 inputs set values for setting the winding length and the speed of the object 10 according to the article to be manufactured or the required winding speed.
The winding system 200 sets a virtual spindle based on the start command, the winding length setting, and the speed setting. The winding length set value is a set value for determining the speed of the object 10. The speed set value is a set value for determining the conveyance amount of the object 10. The virtual main shaft is a virtual position command calculated from the moving amount of the winding length setting value and the speed of the speed setting value. The web motor M1, the winding motor M4, and the feed motor M5 are driven in correspondence with the virtual spindle.
The web motor M1 drives the web 11 at a speed corresponding to the winding length setpoint and the speed setpoint. The web motor M1 is driven under control based on the position of the dancer roller 46 and the measurement result of the circumference of the winding shaft 52. For example, the speed command input to the web motor M1 may be generated by PI control set based on the position of the dancer roller 46.
The circumference of the winding rotary shaft 52 is measured based on signals from at least 1 pulse generator PG of the coil motor M1, the feed motor M5, and the pulse generators PG of the dancer roller control M3. The winding system 200 of this example uses the circumference measurement to control the conveyance speed of the web motor M1, but may also be used to control the winding motor M4 and the conveyance motor Mf.
The feed motor M5 drives the feed rotary shaft 42 at a speed corresponding to the winding length set value and the speed set value. The feed motor M5 of the present example operates in accordance with the generated speed command, but may operate in accordance with a position command. The feed motor M5 may be operated based on a speed command corresponding to position information from the dancer control M3.
The dancer control M3 operates the dancer 46 to maintain a torque corresponding to a predetermined torque command. The torque command may be generated based on a tension set value input from the outside. The torque command is preferably fixed.
The winding motor M4 operates in accordance with the position command and the shape of the winding rotation shaft 52. The position command is generated based on the virtual spindle. The shape of the winding rotary shaft 52 is measured based on the winding speed of the winding motor M4 and the output of the pulse generator PG from the length measuring roller 48.
Fig. 5 shows a more specific example of the structure of the winding shaft 52. The figure shows an XY plane in which the rotation axis of the winding rotation axis 52 is set as the origin (0, 0). The feed contact point of the feed roller 44 is configured to: the X component is the same as the X component of the rotation axis of the winding rotation axis 52, and the Y component is a distance Y from the rotation axis of the winding rotation axis 520. Thus, the feed contact point of feed roller 44 is shown as (0. Y)0). In the present example, the case where the feed contact point of the feed roller 44 coincides with the X component of the rotation axis of the winding rotation axis 52 has been described, but the present invention is not limited to this.
The contact point between the winding rotation axis 52 and the object 10 during winding is represented as (X, Y). The contact point (X, Y) is changed according to the change of the winding angle thetaChanges are made. The length of the winding rotation shaft 52 in this example is L52And has a symmetrical shape with the rotation axis (0, 0) as the center. Therefore, when the winding angle θ is 0 ° to 180 °, the change in the contact point (X, Y) is equal to that when 180 ° to 360 °. In other words, when the winding angle θ is 0 ° to 180 °, the change in the path length L is equal to that when 180 ° to 360 °.
Fig. 6 shows the measuring roll conveyance amount, the winding angle, and their offset amounts from the reference. The vertical axis represents a winding angle θ ° of the winding rotation shaft 52, and the horizontal axis represents a conveyance amount mm of the length measuring roller 48. Curve a is a reference line when the winding rotation axis 52 is assumed to be circular. Curve B is a curve when the non-circular winding rotation shaft 52 is used. Curve C shows the deviation of the reference from the actual control amount. That is, curve C shows the difference between curve a and curve B.
The curve B shows an example of the relationship between the conveyance amount of the length measuring roller 48 and the winding angle θ calculated by the calculation section 20. That is, the curve B is an example of information on the shape of the winding rotation shaft 52 calculated by the calculation unit 20. However, the calculation unit 20 need not chart the relationship between the conveyance amount of the length measuring roller 48 and the winding angle θ, and may calculate data indicating the relationship between the conveyance amount of the length measuring roller 48 and the winding angle θ. Therefore, the control unit 30 can control at least one of the winding motor M4 and the conveyance motor Mf so that the conveyance amount corresponds to the winding angle θ of the winding rotation shaft 52. Therefore, the control device 100 of this example can control the winding of the object 10 on the winding rotation shaft 52 only by the amount shown by the curve C even when the winding rotation shaft 52 is not circular.
As described above, the control device 100 disclosed in the present specification can fix the tension of the holding object 10 even when the winding rotation shaft 52 is not circular. Therefore, the winding system 200 can uniformly wind the object 10 around the winding rotation shaft 52. In this manner, the winding system 200 can suppress the tension fluctuation caused by the shape of the winding rotation shaft 52 and realize stable winding by fixing the conveyance speed and the winding speed.
The present invention has been described above using the embodiments, but the technical scope of the present invention is not limited to the scope described in the above embodiments. Those skilled in the art will appreciate that various alterations and modifications can be added to the above embodiments. Various modifications and improvements are possible within the scope of the invention as defined in the claims.
