Description

  The present invention relates to a wrap winding device.

  As a wrap winding method, there is a wind-up method in which winding is performed on a bobbin while pressing the wrap against two rollers. In this method, each time the wrap is wound around the bobbin, it is compressed by the roller twice, and after passing the roller, the uncompressed wrap sucks in air. Therefore, since the wrap repeats sucking and discharging air, fibers are intertwined between the sheets, which prevents smooth peeling of the wrap (referred to as licking) when the wrap is used in a comb, and the wrap density of the wrap And the bobbin can not have enough weight. In addition, a lap | wrap means the thing which put a plurality of sliver (usually 20-36) in order, and made it the sheet form of about 30 cm in width.

  In order to compensate the above-mentioned fault, a wrap winding device as shown in FIGS. 10 and 11 has been proposed (see Patent Document 1). In the winding device, an endless belt 51 is wound around rollers 52, 53, 54, 55, 56, 57, 58, and the tension of the belt 51 is adjusted by a pressure roller 59. In addition, the roller 52 drives the belt 51. The wrap L is wound around the bobbin 60 in a state in which the bobbin 60 is disposed on the portion of the belt 51 which is looped between the rollers 52 and 53. When winding the wrap L on the bobbin 60, all the rollers 52 to 58 are held at the same position, and the position of the pressure roller 59 is adjusted as the winding amount of the wrap L on the bobbin 60 increases. Is to always apply the same pressing force to the wrap L wound on the bobbin 60.

  The roller 53 is supported at the end of the lever 61, and as shown in FIG. 11, when the wrap L is fully wound on the bobbin 60, the lever 61 is rotated clockwise in FIG. 53 separates from the roller 52 and is moved to a position where the full wrap is released from the loop of the belt 51 and the full wrap is taken out. Thereafter, the lever 61 is pivoted to place the roller 53 in the winding position. While the roller 53 returns to the winding position, the bobbin 60 is supplied from the bobbin supply unit 62 onto the belt 51 through the gap between the rollers 52 and 53, and after the roller 53 returns to the winding position, the roller 52 When driven, winding of the wrap L on the bobbin 60 is performed as shown in FIG.

  In the wrap winding device of Patent Document 1, the bobbin 60 is simply placed on the belt 51, and winding of the wrap L is performed in a state of being pressed toward the both rollers 52 and 53 by the belt 51. Therefore, when the wrap L is wound around the bobbin 60, the axial position of the bobbin 60 is not stable, and the wrap L can not be wound around the bobbin 60 in a predetermined range in the axial direction of the bobbin 60. Become.

  On the other hand, there has been proposed a winding device for winding a wrap around a bobbin driven so as to be rotated at a fixed position by a circulating endless belt (see Patent Document 2). This winding device winds the wrap L around a bobbin 72 driven by a circulating endless belt 71, as shown in FIG. The bobbin 72 is rotatably disposed about a fixed axis 75 in a loop 74 formed between two deflection rollers R1 and R2 of a belt 71 tensioned by a tension adjustment device 73. There is. The bobbin 72 and both diverting rollers R1, R2 are sized and positioned relative to each other such that at the beginning of the winding process the loop 74 surrounds the bobbin 72 with an initial minimum wrap angle greater than 120 ° There is.

  The belt 71 is also wound around diverting rollers R3, R4, R5 other than the diverting rollers R1, R2, and the diverting rollers R4, R5 are below the wrap roll 76 when the belt 71 is full. It is disposed at a position to travel in a passing state. The deflecting roller R5 rotates at a fixed position, and the deflecting roller R4 can be moved by the tension adjusting device 73 between the position in the winding start state shown by the two-dot chain line in FIG. 12 and the position in the full tube state shown by the solid line. Provided in The tensioning device 73 is connected to the controller 77 in order to create a tension related to the diameter of the wrap 76.

  As shown in FIG. 13, the bobbin 72 is clamped between the two winding plates 78 and 79. Both winding plates 78 and 79 are provided with projections 80 and 81, and are fixed to the projections 80 and 81 in a state where the bobbin 72 is fitted.

  Since the sliver, which is the raw material of the wrap, is a cotton lump and is an elastic body containing a large amount of air, it is necessary to hold the wrap against the bobbin by some method when winding the wrap around the bobbin and wind while winding the air. At that time, the wraps pressed from both sides in the thickness direction expand in the width direction. In addition, since the wrap after being wound is also pressed and loosened repeatedly to repeat suction and discharge of air, it gradually expands in the width direction. In order to suppress this, in Patent Document 2, winding plates (flanges) 78 and 79 are provided on the left and right of the bobbin 72, respectively.

  However, when winding plates (flanges) 78 and 79 are provided, as shown in FIG. 13, a gap t between the belt 71 and the winding plates (flanges) 78 and 79 is required, and cotton is pushed out from that portion (Mainly causes ear licking).

  Moreover, in patent document 2, the bobbin 72 is supported so that it may rotate at a fixed position centering on the axis 75 from a winding-up start to a full pipe. Therefore, the wrap L tends to suck in air while moving from the deflecting roller R2 to the winding position relative to the bobbin 72 for a considerable time after the start of winding. As a result, since the wrap L wound around the bobbin 72 is in a state where the wrap L contains a lot of air on the side close to the bobbin 72 of the wrap winding 76, the wrap L with little air is wound outward. The wrap L bulges in the width direction, and is entangled with the end of the wrap L to be wound up next, which makes it easy for the ear to lick.

  The present invention has been made in view of the above problems, and an object thereof is to stably wind a wrap at a predetermined position in the axial direction of the bobbin and suppress licking when winding the wrap on the bobbin. It is an object of the present invention to provide a wrap winding device capable of

  A wrap winding device which solves the above-mentioned subject is a wrap winding device which winds a wrap compressed by a calendar roller on a bobbin rotated by an endless belt wound around a plurality of guide rollers. The bobbin is fixed in a state in which the movement of the bobbin in the axial direction is restricted by the restriction mechanism, and is connected to at least one side of the bobbin support shaft rotatably supported by the bearing and at least one side of the bobbin support shaft And a guide mechanism which regulates the movement of the bobbin support shaft in the axial direction and guides the movement of the bobbin support shaft in the direction perpendicular to the axial direction.

  According to this configuration, winding is started from a state where the bobbin is pressed by the two guide rollers via the belt, so the range of the wrap not pressed by the belt is different from the device of Patent Document 2, It is minimized regardless of the wrap diameter. Therefore, the amount of air taken in by the wrap taken up on the bobbin is reduced, and there is no need to remove the air from the wrap by the pressure of the belt, and the quality defect (licking) of the wrap due to the spread of the wrap in the width direction is suppressed . Furthermore, since the winding of the wrap is performed in a state in which the movement in the axial direction is restricted by the bobbin supporting shaft, the bobbin is in the predetermined range of the axial direction of the bobbin with respect to the bobbin unlike the device of Patent Document 1. It is taken up stably. Therefore, when winding the wrap on the bobbin, it is possible to stably wind the wrap at a predetermined position in the axial direction of the bobbin and to suppress licking.

  The bobbin support shaft may be connected to the guide mechanism only at one side. The bobbin support shaft is not limited to one side support but may be both side support, but in the case of one side support, the work of attaching and detaching the bobbin to the bobbin support shaft is simplified as compared to the both side support.

  The guide mechanism includes a plurality of guide shafts extending in a direction perpendicular to the axial direction of the bobbin support shaft, and a slider supported so as to be movable along the guide shaft, and the bobbin support shaft is mounted on the slider The bearing for rotatably supporting may be provided. According to this configuration, it is possible to perform the restriction of the movement of the bobbin support shaft in the axial direction and the guidance of the movement in the direction orthogonal to the axial direction with a simple structure.

  According to the present invention, when winding a wrap on a bobbin, it is possible to stably wind the wrap at a predetermined position in the axial direction of the bobbin and to suppress licking.

First Embodiment
A first embodiment of the present invention will be described below with reference to FIGS.
As shown in FIG. 1, the wrap winding device winds the wrap 19 compressed by the calendar roller 18 on a bobbin 17 rotationally driven by an endless belt 16 wound around a plurality of guide rollers 11 to 15. It is a wrap winding device.

  Among the four rollers constituting the calender roller 18, the final roller 18a, which is the roller with which the wrap 19 is engaged last, presses the wrap 19 downward by the spring 20, as shown in FIG. Provided in As shown in FIG. 1, the other roller 18b rotates in a state in which the spring 20 presses against the roller on the front side (the direction in which the wrap 19 is supplied to the guide roller 11. The left side in FIG. 1). It is configured to

  Of the guide rollers 11-15, when the two guide rollers 11 and 12 wind up the wrap 19, the movement locus of the bobbin support shaft 21 is a bisector of a line connecting the central axes of both the guide rollers 11 and 12 It is arranged at the position where The guide roller 11 is disposed at a position closest to the calendar roller 18 among the guide rollers 11 to 15.

  Below the two guide rollers 11 and 12, two guide rollers 13 and 14 are disposed at positions where the belt 16 is guided to pass below the full bobbin 22. The guide roller 13 is driven by the motor 23 and functions as a drive roller.

  The guide roller 12 is rotatably supported at the second end of the lever 24 whose first end is rotatably supported by the drive shaft of the guide roller 13 and is illustrated by a driving means (not shown) such as an air cylinder. It is provided to be movable to a winding position shown by a solid line in 1 and a doffing position shown by a two-dot chain line.

  The guide roller 14 is disposed below the calender roller 18, and can be moved by the air cylinder 25 to a winding start position P1 shown by a solid line in FIG. 1 and a full tube position P2 and a doffing position P3 shown by a two dotted line. It is provided.

  The guide roller 15 is disposed to abut on the outer peripheral side of the belt 16 at a position closer to the full bobbin 22 than the guide roller 14 disposed at the doffing position P3. As shown in FIG. 2, the width of the belt 16 is formed wider than the width of the wrap 19.

  As shown in FIGS. 3 and 4, the wrap winding device includes a bobbin support shaft 21 for fixing the bobbin 17, a guide mechanism 26 for guiding the movement of the bobbin support shaft 21 in a direction orthogonal to the axial direction, and the bobbin A control mechanism 27 is provided which restricts the movement of the bobbin support shaft 21 of the bobbin 17 fixed to the support shaft 21 in the axial direction.

  The guide mechanism 26 includes a plurality of (two in this embodiment) guide shafts 28 extending in a direction orthogonal to the axial direction of the bobbin support shaft 21, and a slider 29 movably supported along the guide shafts 28. And a bearing 30 provided on the slider 29 and rotatably supporting the bobbin support shaft 21. In this embodiment, the bobbin support shaft 21 is connected to the guide mechanism 26 only at one side, and is supported by one side.

  The slider 29 is held at a position where the bobbin 17 fixed to the bobbin supporting shaft 21 is pressed against the guide rollers 11 and 12 by the belt 16, and wound around the bobbin 17 when winding the wrap 19 on the bobbin 17. As the wrap diameter of the wrap 19 increases, it is moved downward. That is, at the start of winding, the guide mechanism 26 holds the bobbin support shaft 21 at a position where the bobbin 17 is pressed by the two guide rollers 11 and 12 by the belt 16 and winds the wrap 19 wound around the bobbin 17. The movement is guided such that the distance between the bobbin supporting shaft 21 and the guide rollers 11 and 12 increases as the diameter increases. Further, the guide shaft 28 and the slider 29 restrict the movement of the bobbin support shaft 21 in the axial direction.

  A restriction mechanism 27 that restricts the axial movement of the bobbin support shaft 21 of the bobbin 17 fixed to the bobbin support shaft 21 includes a plurality of elastic members 31 provided on the outer surface of the bobbin support shaft 21. As shown in FIG. 2, FIG. 3 (b) and FIG. 4, in this embodiment, the elastic member 31 can contact the inner circumferential surface of the bobbin 17 at two points near the longitudinal end of the bobbin 17, And as shown to Fig.3 (a), a total of six pieces are provided 3 each at equal intervals in the circumferential direction. A passage 32 for supplying compressed air is formed in the bobbin supporting shaft 21 at a position corresponding to each elastic member 31. When the compressed air is supplied from the piping 33 connected to the passage 32 and the compressed air is supplied to the passage 32, each elastic member 31 is held in a state of pressing the bobbin 17, and the bobbin supporting shaft of the bobbin 17 The axial movement of 21 is restricted. In a state where compressed air is not supplied to the passage 32, the restriction of the movement of the bobbin 17 in the axial direction of the bobbin 17 by the elastic member 31 of the restriction mechanism 27 is released.

Next, the operation of the wrap winding device configured as described above will be described.
Prior to the start of winding, the empty bobbin 17 is fixed to the bobbin support shaft 21. When fixing the bobbin 17 to the bobbin support shaft 21, first, the supply of compressed air to the passage 32 of the bobbin support shaft 21 is stopped, and the bobbin 17 can move along the bobbin support shaft 21. Are mounted at predetermined positions of the bobbin support shaft 21. Thereafter, compressed air is supplied to the passage 32. The supply of the compressed air to the passage 32 causes the elastic member 31 to press the bobbin 17, and the bobbin 17 is held in a state in which the movement of the bobbin support shaft 21 in the axial direction is restricted.

  Next, the air cylinder 25 is driven so that the guide roller 14 is disposed at the position shown by the solid line in FIG. 1, and the bobbin 17 is disposed at the winding start position where the belt 16 presses against the guide rollers 11 and 12. . From this state, the motor 23 and the calender roller 18 are driven. The belt 16 is guided by the guide rollers 11 to 15 and moves in the direction of the arrow in FIG. The guide roller 11 is rotated counterclockwise in FIG. The bobbin 17 around which a part of the belt 16 is wound is rotated in the clockwise direction in FIG. 1 together with the bobbin support shaft 21.

  The wrap 19 compressed by the calendar roller 18 and deaired moves in a state in contact with the surface opposite to the surface in contact with the guide roller 11 of the belt 16 moving in a state wound around the guide roller 11, It is guided between the belt 16 and the outer surface of the bobbin 17 in contact with the outer surface of the 17. The wrap 19 led between the belt 16 and the outer surface of the bobbin 17 is wound around the bobbin 17 while being pressed by the belt 16 on the outer surface of the bobbin 17 as the belt 16 moves.

  As the winding diameter of the wrap 19 wound around the bobbin 17 increases, the bobbin support shaft 21 moves on a bisector of a line connecting the central axes of both guide rollers 11 and 12, and the wrap 19 wound around the bobbin 17 Is always pressed against the two guide rollers 11 and 12 at the same position. The belt 16 moves from the winding start position to the full tube position while pressing the wrap 19 (lap L) wound around the bobbin 17 with the belt 16 while being appropriately tensioned by the guide roller 14. Correspond to changes in the diameter of the wrap. Then, the area of the wrap surface not pressed by the belt 16 is minimized regardless of the wrap diameter as in the case of the start of winding.

  In the winding device of Patent Document 2, as shown in FIG. 12, since the bobbin 72 is wound at the same position from the winding start to the full tube, the wrap L wound around the bobbin 72 from the winding start is Until the belt 71 presses the deflecting rollers R1 and R2, the distance of movement of the lap surface exposed to air is large. Therefore, until the wrap L after compressed by the calender roller and deaerated is taken up by the bobbin 72 and covered by the belt 71, the distance for moving in a state capable of sucking in air is large, and the wrap is L is wound on the bobbin 72 in a thick state including air. For this reason, on both sides of the bobbin 72, flanges for suppressing the spread of the end of the wrap L are required.

  However, in this embodiment, after the wrap 19 moves while being wound around the guide roller 11 and enters between the belt 16 and the outer surface of the bobbin 17, the wrap 19 is pressed against the outer surface of the bobbin 17 by the belt 16. It is wound around the bobbin 17 in a stationary state. As a result, the distance traveled in a state where air can be sucked until the wrap 19 after being compressed by the calendar roller 18 and deaerated is taken up by the bobbin 17 and covered by the belt 16 is Compared with the device of Patent Document 2, the wrap 19 is very small, and the wrap 19 is wound around the bobbin 17 in a thin state.

  The bobbin 17 is in a state in which movement in the axial direction is restricted by the bobbin support shaft 21 via the restriction mechanism 27 and in a state where the bobbin 16 is pressed against the guide rollers 11 and 12 by the belt 16 via the wrap 19. 21 is rotated in the winding direction. Therefore, even if the flange is not provided, the wrap 19 can be wound up to the proper position of the bobbin 17 without any problem.

  Further, in the winding device of Patent Document 2, from the start of winding until the wrap L wound around the bobbin 72 is pressed by the direction change rollers R1 and R2 via the belt 71, the belt 71 is bobbin It is necessary to receive the force for pressing the support 72 by the support shaft of the bobbin 72, and the support shaft of the bobbin 72 needs to have a sufficient strength to sufficiently bear the pressing force of the belt 71.

  However, in this embodiment, since the surface of the bobbin 17 is pressed against the guide rollers 11 and 12 via the belt 16 or the wrap 16 wound around the belt 16 and the bobbin 17 from the start of winding, the belt 16 It is not necessary for the bobbin support shaft 21 to bear the pressing force acting on the bobbin 17 from the above.

  As shown in FIG. 5, when the winding progresses to the full tube, the driving of the calender roller 18 and the motor 23 is stopped, and the winding is completed. Then, the lever 24 supporting the guide roller 12 is moved to the doffing position shown by a two-dot chain line in FIG. 1, and the guide roller 14 is moved from the full pipe position P2 to the doffing position P3 closer to the guide roller 15 , The doffing work is done. After the end of the doffing, the bobbin 17 is attached to the bobbin supporting shaft 21 and the guide rollers 12 and 14 are moved to the winding start position, and the winding of the wrap 19 is started again.

According to this embodiment, the following effects can be obtained.
(1) The wrap winding device winds the wrap 19 compressed by the calendar roller 18 around a bobbin 17 which is rotated by an endless belt 16 wound around a plurality of guide rollers 11-15. In the wrap winding device, the bobbin 17 is fixed in a state in which the movement of the bobbin 17 in the axial direction is restricted by the restriction mechanism 27, and the bobbin support shaft 21 rotatably supported by the bearing 30 on at least one side; A guide mechanism 26 is connected to one side of the shaft 21 to restrict the movement of the bobbin support shaft 21 in the axial direction and guide the movement of the bobbin support shaft 21 in the direction orthogonal to the axial direction.

  According to this configuration, the bobbin 17 does not have a flange, and the winding is started from the state of being pressed by the two guide rollers 11 and 12 via the belt 16. Therefore, unlike the device of Patent Document 2 in which the wrap is wound via a belt on a bobbin having a flange, the compressed wrap 19 gets in between the belt and the flange, and the end of the wrap 19 is prevented from licking. Be done.

  Moreover, after passing the guide roller 11, the range of the wrap 19 not pressed by the belt 16 is minimized regardless of the wrap diameter. Therefore, the amount of air taken in by the wrap 19 taken up by the bobbin 17 is reduced, and there is no need to extract the air from the wrap 19 taken up by the bobbin 17 by the pressing force of the belt 16 and the wrap 19 spreads in the width direction Poor quality (licking) of the wrap 19 due to the above is suppressed. Furthermore, since the winding of the wrap 19 is performed in a state where the movement of the bobbin 17 in the axial direction is restricted by the bobbin support shaft 21, the wrap 19 is different from the device of Patent Document 1 with respect to the bobbin 17. It is stably wound in a predetermined range in the axial direction. Therefore, it is possible to stably wind the wrap 19 at a predetermined position in the axial direction of the bobbin 17 and to suppress licking.

  In addition, since the amount by which the wrap 19 sucks air and swells after being taken up by the bobbin 17 is small, the tension of the belt 16 can be set small, and the life of the belt 16 is extended.

  Furthermore, since the outer surface of the bobbin 17 is pressed against the guide rollers 11 and 12 via the belt 16 or the wrap 16 wound around the belt 16 and the bobbin 17 from the start of winding, the bobbin 17 via the belt 16 is It is not necessary for the bobbin support shaft 21 to bear the pressing force acting on the. Therefore, the strength of the bobbin support shaft 21 can be reduced compared to the winding device of Patent Document 2.

  (2) The bobbin support shaft 21 is connected to the guide mechanism 26 only at one side. The bobbin support shaft 21 is not limited to one side support but may be both side support, but in the case of one side support, the work of attaching and detaching the bobbin 17 to the bobbin support shaft 21 is simplified compared to the both side support.

  (3) The guide mechanism 26 includes a plurality of guide shafts 28 extending in a direction orthogonal to the axial direction of the bobbin support shaft 21. The slider 29 is provided with a bearing 30 for rotatably supporting the bobbin support shaft 21. . According to this configuration, it is possible to perform the control of the movement of the bobbin support shaft 21 in the axial direction and the guidance of the movement in the direction orthogonal to the axial direction with a simple configuration.

  (4) The restriction mechanism 27 is formed on the plurality of elastic members 31 provided on the outer periphery of the bobbin support shaft 21 and the bobbin support shaft 21, and can supply compressed air to the positions corresponding to the respective elastic members 31. A passage 32 is provided. Then, in a state where compressed air is supplied to the passage 32, each elastic member 31 is held in a state of pressing the bobbin 17, and movement of the bobbin 17 in the axial direction of the bobbin support shaft 21 is restricted. There is. Therefore, in a state where compressed air is not supplied to the passage 32, the restriction of movement of the bobbin 17 in the axial direction of the bobbin 17 by the elastic member 31 of the restriction mechanism 27 is released, and the bobbin 17 is attached to the bobbin support 21 And it can be easily removed.

Second Embodiment
Next, a second embodiment will be described according to FIG. 7 and FIG.
In the wrap winding device of this embodiment, the relationship between the guide roller 11 and the calender roller 18 is different from that of the first embodiment, and the other configuration is basically the same as that of the first embodiment. The same parts are assigned the same reference numerals and detailed explanations thereof will be omitted.

  As shown in FIGS. 7 and 8, in this embodiment, the calender roller 18 is disposed in such a manner that the plurality of rollers 18a and 18b constituting the calender roller 18 are positioned substantially in the vertical plane, The point that the final roller 18a is pressed against the guide roller 11 via the belt 16 and the wrap 19 is largely different from the first embodiment. Further, the number of the rollers 18b constituting the calender roller 18 is two, which is smaller than that of the first embodiment.

  In the calender roller 18 of this embodiment, as shown in FIG. 8, the final roller 18a is urged by the spring 20 toward the guide roller 11 side of the wrap winding device, and the other roller 18b is disposed on the lower side. The roller 20 is biased by a spring 20 so as to press the roller through the wrap 19. In addition, illustration of the spring 20 is abbreviate | omitted in FIG.

  In this second embodiment, unlike the first embodiment, the last roller 18a of the calender roller 18 is configured to be pressed against the guide roller 11 of the wrap winding device via the belt 16 and the wrap 19 ing. Therefore, the wrap 19 released from engagement with the final roller 18a of the calender roller 18 is immediately pressed by the guide roller 11 through the belt 16 by the roller 18a, and then wound around the outer surface of the bobbin 17 or the bobbin 17. It is wound on the wrapped wrap 19.

  Therefore, unlike the first embodiment, the distance by which the wrap 19 moves until the wrap 19 compressed by the calendar roller 18 is wound around the bobbin 17 is shorter than that in the first embodiment. Therefore, in addition to the same effects as the effects described in (1) to (4) of the first embodiment, the following effects can be obtained.

  (5) In the wrap winding device, the plurality of rollers 18a and 18b constituting the calender roller 18 are disposed substantially on the vertical plane. Then, the final roller 18a is urged against the guide roller 11 by the spring 20 through the belt 16 and the wrap 19 and both rollers 18b press the roller disposed on the lower side through the wrap 19 It is provided in a state of being energized by 20. Therefore, the distance by which the wrap 19 moves until the wrap 19 compressed by the calender roller 18 is wound up by the bobbin 17 becomes short, and after being compressed by the calender roller 18, the wrap 19 is wound up by the bobbin 17 The reference numeral 19 hardly sucks the air, and the spread of the wrap 19 in the width direction can be further suppressed.

The embodiment is not limited to the two embodiments, and may be embodied as follows, for example.
As shown in FIG. 9, in the wrap winding device of the first embodiment, pressing means 40 for pressing the wrap 19 moving together with the belt 16 wound around the guide roller 11 at a position facing the guide roller 11. May be provided. The pressing means 40 includes a pressing roller 41 extending in parallel to the guide roller 11 and a pressing spring 43 biasing the rotation shaft 42 of the pressing roller 41 in a direction approaching the central axis of the guide roller 11.

  In this embodiment, the distance by which the wrap 19 moves until the wrap 19 compressed by the calender roller 18 is wound around the bobbin 17 via the guide roller 11 and the belt 16 is the same as in the first embodiment. long. However, the wrap 19 is pressed by the pressing roller 41 when moving along the periphery of the guide roller 11 with the belt 16 wound around the guide roller 11. Therefore, while the wrap 19 is compressed by the calender roller 18 and then moved to a position corresponding to the pressing roller 41, while the wrap 19 sucks in air, while the wrap 19 moves while being pressed by the pressing roller 41. The air is evacuated. Then, immediately after the air is removed, the wrap 19 is wound around the bobbin 17 while being pressed against the bobbin 17 by the belt 16.

  Therefore, unlike the first embodiment, after being compressed by the calendar roller 18 and deaired, while moving to a position where it is taken up by the guide roller 11, even if the wrap 19 sucks air, it is pressed against the pressing roller 41. Air is vented from the wrap 19 as it passes through the position. Then, as soon as the air is removed, the bobbin 17 is taken up, so that the spread of the wrap 19 in the width direction can be suppressed as compared with the first embodiment.

The number of rollers constituting the calender roller 18 is not limited to three or four, and may be five or more.
As in the second embodiment, in the configuration in which the final roller 18a of the calender roller 18 is pressed against the guide roller 11 via the belt 16, the plurality of rollers 18a and 18b constituting the calender roller 18 have their rotations The configuration is not limited to the configuration in which the axial center is located on a horizontal surface or a vertical surface. For example, it may be configured to be located on a plane located obliquely.

The moving direction of the bobbin 17 between the winding start position and the full pipe position is not limited to the vertical direction. For example, it may be horizontal or oblique.
The restriction mechanism 27 may be provided on the bobbin support shaft 21 so as to cover the open end of the passage 32. Instead of providing the elastic member 31 for each open end, for example, the restriction mechanism 27 is formed on the bobbin support shaft 21. An annular groove passing through the position corresponding to the open end of the passage 32 is formed on the outer peripheral surface of the bobbin support shaft 21. And, a rubber ring formed in an annular shape may be provided in a state of being accommodated in the annular groove. The rubber ring is held at a position retracted from the outer peripheral surface of the bobbin support shaft 21 when compressed air is not supplied to the passage 32, and part of the rubber ring is supplied by supplying compressed air to the passage 32. It projects from the annular groove and supports the bobbin 17.

The bobbin support shaft 21 may be configured to be supported on both sides instead of in a cantilever state.
The following technical ideas (inventions) can be understood from the above embodiment.
(1) In the invention described in any one of claims 1 to 3, the restriction mechanism is formed on a plurality of elastic members provided on the outer periphery of the bobbin support shaft, and the bobbin support shaft And a passage capable of supplying compressed air at a position corresponding to the elastic member, and in a state where compressed air is supplied to the passage, the elastic member is held in a state of pressing the bobbin, The movement of the bobbin in the axial direction of the bobbin supporting shaft is restricted.
