Description

  The present invention relates to an ironing device for pressing a metal foil body onto a winding roll when the rolled metal foil body is wound around the winding roll.

  The ironing device is provided in order to maintain the quality of the metal foil wound around the winding roll. If the metal foil is not pressed against the take-up roll when the metal foil is taken up by the take-up roll, the metal foil tends to be taken up with air drawn into the take-up roll. The metal foil body may shift in the width direction due to the air drawing. Therefore, the metal foil body can be stably wound up without drawing air between the winding roll by pressing the metal foil body against the winding roll with the ironing device. As a result, the quality of the wound metal foil can be maintained satisfactorily.

  A configuration example of the ironing device will be described with reference to FIG. In FIG. 1A, the ironing device includes a cylinder device 31, a swing arm 33, and an ironing roll 35. The swinging arm 33 is swung in the direction of the arrow in FIG. An ironing roll 35 is attached to the swing arm 33. The ironing roll 35 is arranged so that the central axis thereof is parallel to the central axis of the winding roll 37. As the swing arm 33 swings, the ironing roll 35 presses the metal foil 1 against the take-up roll 37.

  The ironing apparatus as described above is described in, for example, Patent Document 1 below.

Japanese Patent Laid-Open No. 2004-136302

  There is a demand for maintaining the quality of the wound metal foil even when the coil 1a has a large diameter.

For example, when the dimension (coil outer diameter) of the coil 1a formed by the wound metal foil 1 is increased from the state of FIG. 1A to the state of FIG. 1B, the ironing roll 35 is made of metal. The circumferential distance between the position a (see FIG. 1) in contact with the foil body 1 and the winding position b (see FIG. 1) (that is, the distance around the central axis of the winding roll 37) is the above-described air entrainment. It shifts from the position (for example, 20 mm) desirable for prevention. As a result, the shape of the coil 1a formed by the wound metal foil body 1 may become unstable.
For this reason, even if the diameter of the coil 1a is increased, by suppressing the change in the circumferential distance, the coil shape does not become unstable, and the metal foil body is stably wound. It is desired to maintain good quality of the coil 1a.

In another example, when the winding amount of the coil 1a is large, the direction of the cylinder device 31 is greatly different between the start of winding and the end of winding. As a result, the direction of the pressing force by the cylinder device 31 varies greatly, and the pressing of the metal foil body 1 on the winding roll 37 may become unstable.
For this reason, even if the diameter of the coil 1a is increased, the coil shape does not become unstable by reducing the variation in the direction of the pressing force by the cylinder device 31, thereby improving the quality of the coil 1a. It is desired to maintain it well.

  That is, an apparatus capable of winding a metal foil body more stably than the ironing apparatus having the configuration shown in FIG. 1 is required in response to the case where the diameter of the coil 1a is increased.

  Then, the objective of this invention is providing the ironing apparatus which can wind up a metal foil body stably, even if a coil enlarges in diameter.

In order to achieve the above object, according to the present invention, when winding a rolled metal foil body around a winding roll, an ironing device for pressing the winding metal foil body against the winding roll,
An ironing roll that presses the metal foil being wound onto the winding roll;
A rocking body having an ironing roll attached to one end side;
A reciprocating body to which the other end of the rocking body is swingably attached;
A drive device for moving the reciprocating body back and forth with respect to the winding roll; and
A pressing device that generates a force for pressing the metal foil against the take-up roll, and
The pressing device applies a force to the oscillating body so that the oscillating body oscillates on the winding roll side, and thereby presses the metal foil body against the winding roll via an ironing roll attached to the oscillating body. An ironing device is provided.

According to a preferred embodiment of the present invention, a dimension sensor for detecting a dimension of a coil formed by a metal foil wound around a winding roll;
A position sensor for detecting the position of the reciprocating body;
A control device that controls the driving device based on a detection value of the dimension sensor, a detection value of the position sensor, and a preset operation pattern;
The operation pattern defines the position of the reciprocating body with respect to each dimension of the coil.

According to a preferred embodiment of the present invention, the pressing device has a cylinder and a piston, and is a cylinder device that can be extended and retracted by reciprocation of the piston.
One of the cylinder and the tip of the piston is rotatably coupled to one end of the oscillator, and the other of the cylinder and the piston is rotatably coupled to the reciprocating body. Thus, the oscillating body is pressed in the direction in which the oscillating body oscillates toward the take-up roll by the fluid pressure supplied to at least one of the rod side cylinder chamber and the head side cylinder chamber of the cylinder,
The operation pattern is set so that the cylinder device continues to contract without expanding.

According to another preferred embodiment of the present invention, the operation pattern is set to suppress a variation in the distance between the position where the ironing roll contacts the metal foil body and the winding position,
The winding position is a boundary position between the metal foil body that has already been wound around the ironing roll and the metal foil body that is to be wound up.

According to a preferred embodiment of the present invention, it further comprises a force sensor for detecting the force generated by the pressing device,
The control device controls the pressing device based on a detection value of the force sensor, a detection value of the dimension sensor, and a preset pressing force pattern,
The component of the pressing force in the direction from the position where the ironing roll applies the pressing force to the metal foil body toward the central axis of the winding roll is the center direction component,
In the pressing force pattern, the force generated by the pressing device is determined for each dimension of the coil so that the center direction component is constant regardless of the dimension of the coil.

  According to the above-described present invention, the reciprocating body is attached to the reciprocating body so as to be able to oscillate, and the pressing body swings the oscillating body toward the take-up roll and presses the ironing roll against the take-up roll. Thus, the position of the ironing roll or the swinging of the swinging body can be adjusted, whereby the metal foil body can be stably wound even if the diameter of the coil is increased.

  For example, the pressing device presses the ironing roll against the metal foil body by applying a force to the swinging body so that the swinging body swings toward the winding roll. At this time, since the swinging body swings by an amount corresponding to the position of the reciprocating body, if the position of the reciprocating body changes, the contact position (the pressing position to the metal foil body) where the ironing roll contacts the metal foil body is also obtained. change. Therefore, the adjustable range of the contact position is expanded. As a result, the metal foil can be stably wound even if the coil has a large diameter.

  In another example, it is possible to suppress fluctuations in the direction of the pressing force generated by the pressing device by adjusting the position of the reciprocating body to adjust the swing angle of the swing body. As a result, the metal foil can be stably wound even if the coil has a large diameter.

  The effect by embodiment of this invention is clarified below.

  FIG. 2 is a configuration example of the ironing device 10 according to the embodiment of the present invention. The ironing device 10 is a device that presses the metal foil body 1 being wound against the winding roll 3 when the rolled metal foil body 1 such as aluminum is wound around the winding roll 3. FIG. 3 is also a configuration diagram of the ironing device 10 according to the embodiment of the present invention. FIG. 2 shows the start of winding of the metal foil body 1 onto the winding roll 3, and FIG. 3 shows a state where the metal foil body 1 is wound up to some extent on the winding roll 3. The metal foil body 1 wound around the winding roll 3 is a metal foil body (for example, a thickness of 0.01 mm to 0.5 mm) rolled by a roughing mill, or a metal foil body (for example, rolled by a finishing mill) (for example, And a thickness of 0.01 mm to 0.03 mm). 2 and 3, reference numeral 6 denotes a guide roll that supports and guides the metal foil body 1.

  The ironing device 10 includes an ironing roll 5, a rocking body 7, a reciprocating body 9, a driving device 11, a pressing device 13, a dimension sensor 15, a position sensor 17, a control device 19, and a force sensor 21.

The ironing roll 5 presses the metal foil 1 being wound around the winding roll 3 against the winding roll 3. Ironing roll 5, the central axis C _r is parallel to the center axis C ₁ of the winding roll 3. The ironing roll 5 presses the metal foil 1 wound around the take-up roll 3 against the take-up roll 3, thereby preventing air entrainment of the metal foil 1 and stable winding of the metal foil 1. Let In FIG. 2, the axes _{C 1, C 2, C 3} , C 4, C r extends in a direction perpendicular to the paper surface.

The swinging body 7 has an ironing roll 5 attached to one end side. Ironing roll 5, in a state mounted on the oscillator 7, is rotatable on the central axis C _r around.

The reciprocating member 9, the other end portion of the oscillator 7 is swingably attached to the pivot shaft C ₂ around. Preferably, the reciprocating body 9 is supported by the guide rail 12 so as to be able to reciprocate, and the reciprocating motion is guided to the guide rail 12.

  The driving device 11 moves the reciprocating body 9 back and forth with respect to the winding roll 3. This back-and-forth movement is a direction along the guide rail 12 in the example of FIG. The driving device 11 may have a cylinder and a piston (rod), and may be a cylinder device that can be extended and retracted by reciprocation of the piston. In this case, one of the cylinder and the tip of the piston (in the example of FIG. 2, the tip of a piston 11d described later) is coupled to the reciprocating body 9, and the other of the cylinder and the tip of the piston (in FIG. 2). In the example, a cylinder 11 a) described later is fixed to the reference body 23. The reference body 23 is a stationary support structure. In this configuration, the cylinder device is expanded and contracted by a fluid pressure (hydraulic pressure such as hydraulic pressure or pneumatic pressure; the same applies hereinafter) supplied to at least one of the rod side cylinder chamber and the head side cylinder chamber of the cylinder, and the winding roll 3, the reciprocating body 9 is moved back and forth. The drive device 11 is preferably a hydraulic cylinder device as in the example of FIG. The hydraulic cylinder device will be described in detail in an embodiment described later.

The pressing device 13 generates a force that presses the metal foil body 1 against the take-up roll 3. The pressing device 13 applies a force to the oscillating body 7 in the direction in which the oscillating body 7 oscillates toward the take-up roll 3, thereby winding the metal foil body 1 via the ironing roll 5 attached to the oscillating body 7. Press against the take-up roll 3.
The pressing device 13 may have a cylinder and a piston (rod), and may be a cylinder device that can expand and contract by reciprocating movement of the piston. In this case, (in the example of FIG. 2, the distal end of the piston 13g which will be described later) one of the distal end portion of the cylinder and the piston is rotatably coupled to the rotating shaft C ₃ around the other end of the rocking body 7, the cylinder and (in the example of FIG. 2, the cylinder 13a to be described later) other piston of the distal end portion is rotatably coupled to the rotating shaft C ₄ around the reciprocating member 9. In this configuration, the oscillating body 7 is moved toward the take-up roll 3 by fluid pressure (hydraulic pressure such as hydraulic pressure or pneumatic pressure; the same applies hereinafter) supplied to at least one of the rod side cylinder chamber and the head side cylinder chamber of the cylinder. The rocking body 7 is pressed in the rocking direction.
The pressing device 13 is preferably an hydraulic / pneumatic cylinder device as in the example of FIG. The hydraulic / pneumatic cylinder device will be described in detail in an embodiment described later.

The dimension sensor 15 detects the dimension of the coil 1 a formed by the metal foil body 1 wound around the winding roll 3.
For example, the dimension sensor 15 is a known sensor that detects the position of the outer surface of the coil 1a (hereinafter referred to as the outer surface position) (for example, a sensor that optically detects the position without contacting the outer surface). It's okay. In this case, the detected outer surface position may be output to the control device 19 as a dimension detection value of the coil 1a, or the detected outer surface position may be output to the center of the coil 1a (ie, the central axis C of the winding roll 3). ₁ ) may be converted into a distance from the outer surface of the coil 1a (hereinafter referred to as a diameter dimension), and the diameter dimension may be output to the control device 19 as a dimension detection value of the coil 1a.
As another example, the dimension sensor 15 may measure the number of rotations of the winding roll 3 from the start of winding of the metal foil body 1 by the winding roll 3. In this case, the dimension sensor 15 calculates the outer surface position or the diameter dimension based on the number of rotations, the known thickness of the metal foil body 1, and the known dimension of the winding roll 3, and calculates the calculated value. Alternatively, it may be output to the control device 19 as a dimension detection value of the coil 1a.

  The position sensor 17 detects the position of the reciprocating body 9. The position sensor 17 is an optical linear scale in the example of FIG. 2, but may be other appropriate means.

  The control device 19 drives the driving device based on the detection value of the dimension sensor 15 (that is, the dimension detection value), the detection value of the position sensor 17 (that is, the position of the reciprocating body 9), and a preset operation pattern. 11 is controlled. The said operation pattern defines the position of the reciprocating body 9 with respect to each dimension of the coil 1a. Thereby, the control apparatus 19 controls the drive device 11 so that the operation | movement of the reciprocating body 9 follows the said operation pattern.

  The first or second operation pattern may be used as the operation pattern.

The first operation pattern is that the reciprocating body 9 is not stretched by the pressing device 13 (that is, the cylinder device) from the start of winding of the metal foil body 1 by the winding roll 3 to the end of winding. It is set to continue to degenerate. The control device 19 controls the driving device 11 based on the first operation pattern, so that the pressing device 13 always continues to degenerate from the start of winding to the end of winding.
Thereby, the fluctuation | variation of the pressing force to the metal foil body 1 by the ironing roll 5 can be suppressed as follows. As the coil size increases, the pressing device 13 can be continuously degenerated. Therefore, the operation direction of the pressing device 13 (piston of the cylinder device) is not temporarily reversed. As a result, the pressing force generated by the pressing device 13 and the direction of the mechanical friction force of the pressing device 13 are not reversed and fluctuated. Therefore, it can suppress that the pressing force with respect to the metal foil body 1 of the ironing roll 5 is fluctuate | varied by such fluctuation | variation of pressing force and frictional force.

The second operation pattern is the circumferential distance along the outer surface of the coil 1a between the position a (see FIG. 3) where the ironing roll 5 contacts the metal foil body 1 and the winding position b (see FIG. 3). (i.e., the center axis C ₁ distance around the take-up roll 3) is in until the completely wound from the time the winding start is set so as to suppress the variation. Preferably, the second operation pattern is set so that the circumferential distance is constant from the start of winding by the winding roll 3 to the end of winding, or so that the circumferential distance is as constant as possible. Set. For example, the second operation pattern is set so that the circumferential distance is within a range of 0 to 20 mm from the start of winding to the end of winding.
In addition, the winding position b is a boundary position between the metal foil body 1 that has already been wound around the ironing roll 5 and the metal foil body 1 that is to be wound up, as shown in FIG.
As the control device 19 controls the drive device 11 based on the second operation pattern, fluctuations in the circumferential distance are suppressed from the start of winding to the end of winding. Preferably, the circumferential distance is maintained substantially constant from the start of winding to the end of winding or changes within a minimum fluctuation range.
Thereby, the pressing position (namely, position a of FIG. 3) of the ironing roll 5 with respect to the metal foil body 1 can be maintained in a desirable range (for example, the range in which the circumferential distance is 0 to 20 mm). If this pressing position deviates greatly from the winding position b, it will not be possible to prevent the metal foil body 1 from being drawn into the air. Therefore, even if the coil 1a dimension increases greatly from the start of winding to the end of winding, the pressing position of the ironing roll 5 can be maintained within a desirable range for preventing air entrainment by the second operation pattern. As a result, the metal foil body 1 can be prevented from being drawn into the air and stable winding can be realized.

Note that the first and second operation patterns cannot be made compatible. If the circumferential distance is controlled to be constant, the operation direction of the pressing device 13 is reversed during winding. Therefore, since the first and second operation patterns cannot be made compatible, one of these is selected.
Further, in both the first and second operation patterns, variation in the direction of the pressing force (force F ₁ described later) generated by the pressing device 13 can be suppressed as compared with the case of FIG.

The force sensor 21 detects a force generated by the pressing device 13 (in this example, a force F ₁ (see FIG. 4) by which the pressing device 13 presses the oscillating body 7). In this case, the control device 19 preferably controls the pressing device 13 based on the detection value (for example, F ₁ ) of the force sensor 21, the detection value of the dimension sensor 15, and a preset pressing force pattern. Pressing force pattern is determined based on the center direction component F ₂ shown in FIG. The center direction component F ₂ is a component of the pressing force F ₃ in the direction from the position where the ironing roll 5 provides a pressing force F ₃ to the metal foil element 1 to the center axis C ₁ of the winding roll 3. Pressing force pattern, as the center direction component F ₂ is constant irrespective of the size of the coil 1a, the force pressing device 13 is generated (in this example, the force F ₁ which the pressing device 13 presses the oscillator 7 ) For each dimension of the coil 1a.
That is, the dimensions and the operation pattern of the coil 1a at each time point, the position of the pivot shaft C _2, and, ironing roll 5 and the tangent of the position a of the coil 1a (FIG. 3, see FIG. 4) is Sadamari, these From the position, the relationship between F ₁ and F ₂ is determined by the following equation (1). Accordingly, the magnitude of F ₂ is set to a predetermined value, and for each dimension of the coil 1a, the predetermined value is constant regardless of the dimension of the coil 1a by the operation pattern and the equation (1). , F ₁ is calculated in advance. Thus, the magnitude of F ₁ calculated for each dimension of the coil 1a can be used as a pressing force pattern.
Thus, the control device 19, the pressing force F ₁ by the pressing device 13 controls the pressing device 13 to follow the pressure pattern.

Each symbol in Formula (1) is defined as follows based on FIG. In FIG. 4, each member is indicated by a thin broken line.

The plane P ₁ is indicated by a thick broken line in FIG. 4 and includes a force vector F ₁ that the pressing device 13 acts on the oscillator 7 and is parallel to the central axis C ₁ of the winding roll 3. It is a plane. Plane P ₂ is shown by a thick more dashed in FIG. 4, it is parallel to the plane P _1, and a plane including the oscillation axis C _2.
L ₂ is the distance between the plane P ₃ and the plane P ₂ . The plane P ₃ is parallel to the plane P ₁ and includes a tangent line a between the ironing roll 5 and the metal foil body 1 (that is, a position a in FIGS. 2 and 4). The tangent line a extends in a direction perpendicular to the paper surface of FIG. 4, and corresponds to a position where the ironing roll 5 applies the force F ₃ to the metal foil body 1 as described above.

  5 is a VV arrow view of FIG. As shown in FIG. 5, the rocking body 7 and the pressing device 13 described above are provided on both sides of the ironing roll 5 in the axial direction. Therefore, the control device 19 controls the pair of pressing devices 13 as described above in synchronization with each other.

  According to the ironing device 10 described above, the metal foil body 1 is stabilized even if the coil 1a has a large diameter by expanding the adjustable range of the position a where the ironing roll 5 contacts the metal foil body 1 as follows. And can be wound up. The pressing device 13 presses the ironing roll 5 against the metal foil body 1 by applying a force to the swing body 7 so that the swing body 7 swings toward the winding roll 3 side. At this time, since the swinging body swings by an amount corresponding to the position of the reciprocating body 9, if the position of the reciprocating body 9 changes, the contact position a (metal foil body 1) where the ironing roll 5 contacts the metal foil body 1. (Pressing position to) also changes. Therefore, the adjustable range of the contact position a is expanded. As a result, even if the diameter of the coil 1a is increased, the metal foil body 1 can be stably wound up.

  Examples of the present invention will be described, but the points not described below may be the same as the above-described embodiment.

  In the embodiment, the drive device 11 is a hydraulic cylinder device. In this case, the hydraulic cylinder device 11 has the following configuration and is controlled by the control device 19 as follows.

  As shown in FIG. 2, the hydraulic cylinder device 11 includes a cylinder 11a, a hydraulic pressure source 11b, a servo valve 11c, and a rod (piston) 11d. A head side cylinder chamber 11a-1 and a rod side cylinder chamber 11a-2 are formed in the cylinder 11a. As shown in FIG. 2, the hydraulic pressure source 11b is connected to the head side cylinder chamber 11a-1 and the rod side cylinder chamber 11a-2 by a hydraulic pressure supply pipe 11e. The servo valve 11c is provided in the hydraulic pressure supply pipe 11e and adjusts the hydraulic pressure supplied from the hydraulic pressure source 11b to the head side cylinder chamber 11a-1 and the rod side cylinder chamber 11a-2. The rod 11d reciprocates back and forth with respect to the take-up roll 3 by the hydraulic pressure supplied to the head side cylinder chamber 11a-1 and the rod side cylinder chamber 11a-2. The tip of the rod 11d is coupled to the reciprocating body 9, so that the reciprocating body 9 reciprocates integrally with the rod 11d.

  The control device 19 controls the hydraulic cylinder device 11 based on the detection value of the dimension sensor 15, the detection value of the position sensor 17, and a preset operation pattern (preferably the first or second operation pattern). Control. Specifically, the control device 19 controls the servo valve 11c so that each detected value of the dimension sensor 15 is reciprocated at the position of the reciprocating member 9 determined for the detected value in the operation pattern. 9 is controlled to be located.

  The pressing device 13 is an oil / pneumatic cylinder device. In this case, the hydraulic / pneumatic cylinder device 13 has the following configuration and is controlled by the control device 19 as follows.

The hydraulic / pneumatic cylinder device 13 includes a cylinder 13a, a pneumatic pressure source 13b, servo valves 13c and 13d, a first air-hydro converter 13e, a second air-hydro converter 13f, and a rod (piston) 13g. Cylinder 13a is in reciprocating member 9 is rotatably mounted on the rotary shaft C ₄ around. The air pressure source 13b is, for example, a compressor, and is connected to the air chambers 13e-1 and 13f-1 of the first and second air hydroconverters 13e and 13f by an air pressure supply pipe 13h as shown in FIG. . The servo valve 13c adjusts the air pressure supplied from the air pressure source 13b to the first and second air-hydro converters 13e and 13f. The servo valve 13d adjusts the air pressure supplied from the air pressure source 13b to the first air-hydro converter 13e. The oil chamber 13e-2 of the first air hydroconverter 13e is connected to the rod side cylinder chamber 13a-2 of the cylinder 13a, and the oil chamber 13f-2 of the second air hydroconverter 13f is the head side cylinder of the cylinder 13a. Connected to chamber 13a-1. By adjusting the pneumatic pressure supplied to the air chambers 13e-1 and 13f-1 in the first and second air-hydro converters 13e and 13f by the servo valves 13c and 13d, the head side cylinder chamber 13a- of the cylinder 13a is adjusted. 1 and the hydraulic pressure supplied to the rod side cylinder chamber 13a-2. Thus, rotatably mounted rod 13g to the rotation axis C ₃ around the oscillator 7, the oscillator 7 is allowed to act a force on the oscillator 7 in the direction that swings the winding roll 3 side, as a result, The metal foil body 1 is pressed against the take-up roll 3 through the ironing roll 5 attached to the rocking body 7. Further, since the hydraulic / pneumatic cylinder device 13 has the air-hydro converters 13e and 13f, even if it receives an impact from the metal foil body 1 via the ironing roll 5 and the swinging body 7, this impact is transferred to the air-hydro converter. It can be absorbed by the air pressure of 13e and 13f. Therefore, even if vibration is generated by increasing the winding speed of the winding roll 3 and the ironing roll 5 receives an impact, it can be absorbed. In FIG. 2, reference numerals 13e-3 and 13f-3 denote pistons of the air-hydro converters 13e and 13f, respectively.

The control device 19 controls the hydraulic / pneumatic cylinder device 13 based on the detection value of the force sensor 21, the detection value of the dimension sensor 15, and a preset pressing force pattern. More specifically, for each detected value of the dimension sensor 15, are determined with respect to detected value in pressing force pattern, a force F ₁ the rod 13g presses the oscillator 7, the rod 13g is the oscillator 7 The control device 19 controls the servo valves 13e and 13f so as to press.

In the example of FIG. 2, the force sensor 21 includes a pressure sensor 21a for detecting the pressure in the head side cylinder chamber 13a-1 and a pressure sensor 21b for detecting the pressure in the rod side cylinder chamber 13a-2. Control device 19, the pressure sensor 21a, on the basis of the detected value of 21b, by controlling the servo valve 13c, the 13d, the pressing force _{F 1} of the above is to follow the pressing force pattern.
Here, the control device 19 controls the servo valve 13d based on the detection value of the pressure sensor 21b so that the hydraulic pressure in the rod side cylinder chamber 13a-2 is maintained at a constant set value, and at the same time, the pressure sensor 21a. Based on the detected value, the servo valve 13c is controlled so that the hydraulic pressure in the head side cylinder chamber 13a-1 follows the pressing force pattern.

(5) The first operation pattern shown in FIG. 6A is obtained based on the degeneration speed pattern based on the curve approximated in the above (4) and the geometric shape and dimensions of the ironing device 10.

  FIG. 8 is a graph showing the control by the second operation pattern. FIG. 8A shows a second operation pattern, and FIGS. 8B and 8C show results when the second operation pattern in FIG. 8A is followed.

The second operation pattern can be obtained in advance by, for example, the following procedures (1) to (3).
(1) The above-described constant circumferential distance between the pressing position a and the winding position b is set.
(2) The position of the ironing roll 5 is obtained for each dimension of the coil based on the set circumferential distance.
(3) When the position of the ironing roll 5 is obtained for each dimension of the coil, the expansion / contraction amount of the hydraulic cylinder device 11 is obtained from this position and the geometric shape and dimensions of the ironing device 10. That is, the second operation pattern is obtained.
In FIG. 8A, the second operation pattern thus obtained is approximated by a polynomial. In FIG. 8C, the circumferential distance slightly varies from a constant value. However, the second operation pattern does not have to be approximated by a polynomial in order to make the circumferential distance constant.
