Description

201228918 40652pif 6. Technical Field of the Invention The present invention relates to a turret type film winding device and a method of manufacturing a film using the film winding device. The present invention particularly relates to pushing air The air press method is applied to a device improvement in a turret type film winding device. [Prior Art] For example, an optical film such as a protective film, or an optical compensation film, and an antireflection film which requires a highly planar property, such as manufactured Triacetyl Cellulose (TAC), etc. The film itself is used to protect a polarizing plate of a liquid crystal display device, which is manufactured by a processing step of coating, drying, or the like on the manufactured film. The film is generally produced by a solution film forming method or a melt film forming method, and the manufactured sheet is wound around a winding device. Therefore, the winding deviation at the time of winding, the winding wrinkles, the scratches (including minute scratches of about 50 μm to 100 μm), the deformation of the depression at the center of the film, and the deformation of the film end (commonly referred to as the ear) (depression) The winding failure such as collapse or the like becomes a big problem in quality. ·" The winding failure of the film is associated with the subsequent coating failure or drying failure, so the user (user;) will perform a more rigorous inspection of the product film, especially due to the widening of the film in recent years (for example) More than 2000 mm), it is difficult to discharge the air that is entangled during winding, so that it is difficult to cause a winding failure in the winding process. < , , and generally, when the advancing film is wound on the winding shaft to form a winding roll, the carried air carried during the advancement of the film will roll 5 201228918 40652pif into the film layer each other between. Thereby, the roll becomes slack, and a winding failure such as a winding deviation occurs. The depression or collapse is a phenomenon in which the carried air that is wound into the wound winding at the time of winding is discharged from the wound roll as time passes, and the portion where the carried air has been discharged sinks. Therefore, in order to obtain the winding hardness which does not cause winding deviation, it is necessary to remove the carried air at the time of winding. In particular, in recent years, as the width of the film is increased, it is difficult for the carrier air that is wound into the wound roll at the time of winding to be discharged from the rain end portion of the wound roll, so that a winding failure is likely to occur. A conventional general winding method for removing air is a method for improving the winding tension. However, the method of increasing the winding tension has the drawback that the removal of air (especially for the central portion in the width direction of the film) is low, and the ear is generated due to stress concentrated in the width direction of the film. Deformation (sinking or stretching of the knurling portion). Therefore, a winding device has been developed which can remove the carrier air without increasing the winding tension. For example, Patent Document 1 to Patent Document 2 exist. The winding device of Patent Document 1 is configured to wind the wound winding surface of the winding start point by air pressing while squeezing the house, thereby winding the carrier air that is wound into the winding roll. Exclude. However, in the winding device of Patent Document 1, since the pressing is in contact with the film surface, scratches due to slip or the like cannot be prevented. In particular, if a substance such as dust adheres to the surface of the wound roll, it is easy to cause a large scratch due to foreign matter interposed between the squeeze roll and the wound roll. Therefore, in particular, for a winding device for an optical film, in the case of a plurality of 201228918 40652pif, the rice is pressed by an air which is not in contact with the surface of the wound roll, for example, a winding device of Patent Read 2. The winding device of the special document 2 is to take air from an air nozzle (air nozzle to the surface of the winding roll and perform air reduction, whereby the air can be carried to the coiled air without being in contact with the winding (four). [Patent Document 1] [Patent Document 1] Japanese Patent Laid-Open Publication No. 2002-220143 (Patent Document 2) Japanese Patent Laid-Open No. 2005-096915 When the apparatus adopts the air pressing method, as shown by 9, 'the winding roll 1 in the rolled state in which the winding has been completed must be moved from the winding position, and the winding shaft 2 to be wound next is moved to The winding position of the turret type winding device includes a plurality of winding shafts, and = the production line is stopped to continuously wind the film. Therefore, the turret 3 must be rotated around the square rotating shaft 3A. In this case, the following problem occurs: when the turret 3 rotates, the air mouthpiece 4 becomes obstructed 'the air nozzle 4 must be temporarily retracted to the rotational orbit $ of the turret 3. Here, the so-called turn The rotating track of tower 3, as shown in Figure 9, refers to The winding (dotted line) depicted by the outermost edge of the lower wound roll 1 is the longest distance between the winding roll 1 and the center axis of the rotating shaft 3A of the turret. Since the air nozzle 4 is retracted, when When the outer peripheral side of the wound winding 1 having been wound is wound, the surface of the wound winding is not pressed by the air, and thus a winding failure such as the winding deviation occurs on the outer peripheral side. In the conventional winding action, when the winding is performed on the outer peripheral side, the winding tension is increased to cope with the winding failure. However, when the winding is performed on the outer peripheral side, even if the winding is performed, Tension does not solve the winding failure. Especially in the case of a wide-width film with a film width of 2000 mm or more, the carrier air cannot be sufficiently removed, thus causing a wrinkling or collapse winding failure. In addition, even for the film In the case of a film having a width of 20 mm or less, a winding deviation failure frequently occurs when the winding tension is increased. [Invention] The present invention is in view of the above circumstances. The invention has been made to provide a film winding device and a method for producing a film using the same, even when the air pressing method is applied to a turret-type film winding device, in which case the turret rotates In this case, it is not necessary to retract the air nozzle, and the winding of the winding roll can be performed by air pressing until the winding is completed. Therefore, the carrier air can be efficiently removed, and it is most suitable for the surface requiring the height. The film of the performance is wound. In order to achieve the object, a film winding device according to an aspect of the present invention is a film winding device which winds a traveling strip-shaped film around a winding shaft to form a wound roll. The turret provided with the plurality of winding shafts is rotated about the rotation axis, thereby moving the wound winding in the full state from the winding position, and moving the winding shaft to be wound next to the winding shaft In the winding position, the turret type is characterized in that the air ejection unit is integrally provided with the turret for each of the winding shafts, and the air ejection unit Rotating together with the rotation of the turret, the air ejection unit includes at least: an air nozzle 'sprays air to the surface of the winding coil, and presses air on the surface of the winding coil; air guide 201228918 40652pif into the pipeline, hollowly forming the rotating shaft, and introducing air to the air nozzle via the rotating shaft; and moving the mechanism to maintain the distance between the outlet of the air nozzle and the surface of the winding coil At the distance, the gas nozzle is moved while following the change in the winding diameter of the wound winding. Here, the introduction of air into the nozzle via the rotating shaft, in addition to using the rotating shaft itself as a pipe for air pressing, includes disposing an air hose in the rotating shaft the meaning of. According to the film winding device of the above-described manner, the rotation of the air ejecting mechanism p-tower rotates, and the air ejecting mechanism includes the squirting air to the surface of the winding reel, pushing the surface of the winding · The moving mechanism moves the air nozzle; and the air is introduced into the air nozzle. Therefore, it is not necessary to wind the film as in the prior art. When the turret is rotated, the air nozzle is temporarily silvered out of the turret. Therefore, it is of course possible to press the surface of the wound roll from the start of the winding of the film, and even if it is in the thorny, the film is wound up, and the winding is wound around the outer circumference _ winding two. The ground is pressed against the surface of the wound roll. It is effective even when the air (four) pressure method is placed on the turret-type film=device, when the turret is rotated, it is not necessary to evacuate the process nozzle as before, and the film can be wound from the beginning. The winding roll is air-pressed until the winding is completed. This is to prevent the winding failure caused by carrying air.曰 According to the present invention, the domain W unit superior ship is placed in the turret and the turret. In this way, although the turret rotates, the air bleed unit does not come into contact with various types of equipment placed around the turret, and the device can be made compact. According to the invention, it is preferable that a rotary joint is provided to the rotary shaft, and the rotary copper is rotatably coupled to an air pipe until the air source provided outside the turn. Thereby, the air introduction duct is not distorted by the rotation of the turret. The present invention preferably has a configuration in which a guide roller ((4) and a roller (10) guide member are provided to rotate with the turret when the turret rotates, and is wrapped by a film wound around the wound roll (Face p), and in the advancement path of the film of the package = the guide roller, the air ejection sheet 70 is disposed. Thereby, the guide roller can rotate the forward turret of the film. The film in the film will not be single =: by S this will not make the film contact with the air ejection unit and the spray of Wei will be in the mm, the distance between the two or two rolls will be maintained at 2 mm~15 _ ^ mouth _ foot 2匪, and if the distance exceeds 15 m, the two pairs are in contact, and the pressure at the time of pressing is not enough to be carried reliably; = two lines; f even if the winding diameter of the wound winding is changed: in addition, in the present invention, Said air* pays back the branch to the item 201228918 40652pif pip〇, and from the manifold through a plurality of flexible hoses, the air is placed in the width direction of the air nozzle Import. By this, '= make the air nozzle width correspond to the width of the wound film In the case of increasing the size, the surface of the wound winding may be uniformly pressed in the width direction. In the present invention, it is preferable to provide a switching mechanism to the respective manifolds, and the mechanism can be simplified in 3 seconds, and flows from the rotating shaft. The air of each of the winding shafts is switched. Thus, "(4) between the plurality of winding axes = the end of the winding of the winding film can be quickly switched to the air pressing of the winding roll = therefore, In the case of the winding switching, the winding failure caused by the carried air does not occur. In the present invention, it is preferable that the moving mechanism is disposed in such a manner that the Elo of the driving portion is not lowered onto the film. The position of the both ends of the direction of the direction of the direction of the movement is caused by the drive unit of the moving mechanism. In particular, when the film is an optical film, foreign matter adhering to the dust or the like may affect the quality. When the turret drives the air to eject the unit, it is important to prevent the moving mechanism from being attached to the winding coil. The so-called driving portion is, for example, a ball screw (10) or a li-guide. In this & month It is preferable that the driving portion of the moving mechanism is provided with a jcove O. This can reliably prevent the dust generated by the driving portion of the moving mechanism from scattering to the outside. In the present invention, the width of the film is preferably 2000 mm. The above-mentioned. The width of the ίi-Qin film is 2000 峨 or more. When the two nipples are wound up by the winding person, the carrier air is not easily discharged from both ends of the winding roll 11 201228918 4〇652pif. In the present invention, the width of the film is particularly effective when it is 以上 _ or more. Further, even when the thickness _ width is equal to or less than (10), the winding deviation is effectively prevented. To achieve the object, The method for producing a film according to one aspect of the present invention includes: a film forming step of manufacturing a film; and a film roll 2, the film winding device of the method is used to roll the manufactured film Wrap around. The step of preparing the crucible may be, for example, a solution film forming method in which a coating material (dGpe) is cast on a support body into a film form, or a melt film forming method in which the raw material resin is dissolved or dispersed. The molten film forming method is a method in which a molten resin is discharged from a die into a cooling cylinder in a film form, and the molten resin is extruded. The machine is used to melt the raw material resin. According to the method for producing a film according to the above aspect, the winding step of the produced film is performed by the film winding = setting, so that the roll, the crepe deviation, the winding wrinkle, and the scratch are not generated. (including small scratches of about 50 μm to 100 μm), dent deformation at the center of the film, and winding failure of the film end (commonly referred to as ear) (rolling dent or stretch). Thereby, a planar high-quality film can be produced. In order to achieve the above object, the optical film of another aspect of the present invention is characterized in that it comprises at least a film winding step, and the film for manufacturing an optical film is subjected to the film winding device of the above-described manner. Winding; coating step 'rewinding the wound film, coating an optical coating liquid; and drying step 'drying the applied coating layer. According to the method for producing a film of the above aspect, the film is wound by

S 201228918 40652pif ^The winding step of (4) is carried out, so that winding deviation, winding wrinkles, and scratches (including tiny marks of about 50 μm to 100 μm) and/or the center of the film do not occur during winding. The deformation of the depression, and the winding failure of the deformation of the film end (commonly referred to as the ear) (the embossing or stretching of the knurling portion). Thereby, in the coating step or the drying step, the coating failure or the drying failure caused by the winding failure does not occur. Therefore, a high-quality optical film can be manufactured. - In the mode, it is preferred to include a product film winding step of winding the manufactured optical film by the film winding device of the type described. Even when the optical film as a product is wound, a higher quality optical film can be produced by using the film winding device of the present invention. In the above mode, the optical film is preferably any one of a polarizing plate protective film, an optical compensation film, and an antireflection film of a liquid crystal display device. The reason is that such an optical film requires a very high surface energy. [Effects of the Invention] According to the film winding device of the present invention, even when the air pressing method is applied to the turret-type winding device, when the turret is rotated, it is not necessary to retract the air nozzle, and it is possible to At the start of winding, the winding roll is air-pressed until the winding is completed, so that the entire winding length can be ensured with high quality. Further, according to the method for producing an optical film using the winding device, an optical film which requires a high degree of planar properties can be produced. [Embodiment] Hereinafter, the film winding device of the present invention and the use thereof are described in detail.

A preferred embodiment of the method for producing an optical film according to S 13 201228918 40652pif will be described. Fig. 1 is a conceptual view showing a film forming production money 14 in which a turret-type film winding device 10 of the present invention is assembled to a film 12. As shown in Fig. 1, the film 12 produced by the film forming line 14 is wound around a turret-type film winding device 1 via a film roll and a switching device 16. In the present embodiment, the example of the two-axis turret type film winding device having two winding shafts will be described. However, the winding shaft may be two or more. The film forming line 14 may be, for example, a solution film forming method in which a coating material is cast on a support into a film form, or a melt film forming method in which a raw material resin is dissolved or dispersed in a solvent. The melt film forming method is a method in which a molten resin is extruded from a mold into a film in a film form, and the molten resin is obtained by melting a raw material resin by an extruder. Further, the film winding switching device 16 is a device in which the turret rotates after one of the two shafts is wound, and the film 12 is wound when the empty winding shaft is at the winding position. Switch from the full winding axis to the empty winding axis. The detailed description of the film winding switching device 16 is not intended to be the object of the present invention. Therefore, for example, a film winding switching device disclosed in Japanese Laid-Open Patent Publication No. 2008-230723 can be preferably used. The winding drive control unit 10A that drives and controls the winding of the film winding device 10 and the winding switching drive control unit 16A that drives and controls the winding switching of the film winding switching device 16 are based on the controller (controller) ) 18 instructions to control. As shown in Figs. 2 and 3, the two-axis turret type film winding device 1A includes a turret 22 rotatably disposed on the gantry, and an air blasting 201228918 40652pif unit 24 to rotate together with the turret 22. Further, in Fig. 2 and Fig. 3, the posture of the turret 22 during the film winding process is inclined as compared with the horizontal state of Fig. 1, but the posture of the turret 22 is not particularly limited. The table 20 is formed in a concave shape by a bottom plate 2A and a pair of side plates 20B and 20B, and the pair of side plates 20B and 20B are disposed to face each other with a width larger than the width of the film 12. Further, the rotating shaft (rotating shaft) 26 is rotatably supported by a pair of bearings (not shown) provided at the upper end portions of the pair of side plates 20B and 20B. The turret 22 includes a pair of arm-shaped plates 28, 28 that face in parallel, and a central portion of the pair of arm-shaped plates 28, 28 is supported by the rotating shaft 26. The rotary shaft 26 is coupled to a rotational drive source (not shown). Thereby, the turret 22 rotates due to the rotation of the rotating shaft 26. In the present embodiment, the turret 22 is described as an example of an arm-shaped turret, but a disk-shaped turret including a pair of parallel circular plates may be used. Inside the both end portions of the pair of arm-shaped plates 28 and 28 which face in parallel, bosses 30 and 30 project, and the hollow core 31 is fitted and supported by the pair of bosses 30 and 30. Thereby, a winding shaft 32 is formed which is wound around the film 12. Further, the winding shaft 32 as follows is referred to as a first winding shaft 32A, and the winding shaft 32 is wound around the winding position of the film winding switching device 16. Further, the empty winding shaft 32 is referred to as a second winding shaft 32B, and the empty winding shaft 32 stands by at a standby position away from the film winding switching device 16 for the next winding. Further, the winding drive control unit 10A drives and controls the intermittent rotation of the turret 22 (the degree of each rotation) and the rotation of the winding shafts 32A and 32B based on the finger from the controller 18. Further, a winding diameter sensor 15 is provided in the vicinity of the winding position. 201228018 40652pif FIG. 2] The winding diameter sensor (not shown) measures the winding diameter of the wound winding 34 wound around the -U 32A, and checks The signal is sent to control ϋ 18. The control unit 18 performs calculation based on the winding remaining of the winding diameter sensor 34, and if the winding straight # is full, the winding switching command is output to the film winding device 10 and the film roll. The switching device 16 is wound. The air ejecting unit 24 integrally provided with the turret 22 presses the surface of the wound roll 34 with air, thereby preventing the carried air carried by the wound film stack from being caught in the winding roll 34, for each first The air discharge unit 24 is provided by the winding shaft 32Α and the second winding shaft 32Β. That is, the air ejection unit 24 includes an air nozzle 36 that injects air onto the surface of the winding roll 34 to press the surface of the wound winding 34 with air; the air introduction line 38' hollowly forms the rotating shaft 26, and via The rotating shaft 26 introduces air into the air nozzle 36; and the moving mechanism 40 moves the air nozzle 36 following the change in the winding straightness of the winding roll 34. The air ejecting unit 24 is integrally provided with the turret 22 in such a manner as to rotate together with the rotation of the turret 22. The air ejection unit 24 constructed in the above manner is preferably disposed in the rotation track S of the turret 22. The rotation track S of the turret 22, as shown in FIG. 3, refers to the following trace (two-dot chain line) drawn by the outermost edge of the wound roll 34, and the winding roll 34 and the rotation axis of the turret 22 The center of 26 is the longest distance apart. The air nozzle 36 includes a slit-shaped discharge port 36'' which is formed to have the same width as the width of the film 12. The air supplied from the air introduction line 38 is ejected from the discharge port 36A toward the surface of the wound coil 34.

S 201228918 40652pif The air introduction line 38 includes: a plurality of flexible hoses 38B connected to a plurality of air ports 38A formed along the width direction of the air nozzles 36, and a manifold 38C connected to the plurality of flexible hoses mb The other two. And the hollow rotating shaft 26 is in communication with the manifold 38C. Further, the air pipe 42 up to the air generating device (not shown) is connected to the = joint 38D, and the rotary joint 38D is provided on the rotating shaft 26. Thereby, the air ejection unit 24 is rotated 3 together with the rotation of the turret 22, causing the air introduction line 38 to be twisted.多 A plurality of flexible hoses and manifolds 38C are provided for each of the air nozzles 36, and an opening and closing valve (5) (not shown) is provided in each of the totals f 38C. Each of the on-off valves operates in accordance with an instruction from the controller 18. That is, the air is delivered to the total 阙Γ' in the film winding process, and the opening and closing valve of the other manifold 38c is closed. In contrast, the air from the 4 generating device is transferred through the air pipe 42, and the 38D, the hollow rotating shaft 26, the open pipe 38C and the shigen recording hose are thin and supplied to the air nozzle. The air from the air nozzle 36 is directed to the surface of the wound coil 34 at a pressure of 5 kPa to 30 kPa. If you go in, you will carry the air to remove the effect, and push the other side of the force: when the air is pushed, the right side can be "the pressure of pushing back is too strong, it will be wound up too hard, so there is a chance A winding failure of the black belt or the like is caused. The moving mechanism 40 - faces maintains the distance between the air nozzles 36 and the distance between the air gaps 36 and the rods (4) and the f/M 36 moves forward and backward relative to the winding advance, the moving mechanism 40 is configured as follows: 17 201228918 40652pif, that is, an extension is provided from opposite end portions of the pair of arm plates 28 and 28 at opposite ends of the pair of arm plates 28 and 28; The plates 28A, 28A, the arm plate 28 are formed in an N shape, and are orthogonal to the axis of the first winding shaft 32A or the second winding shaft 32B on the inner side of the opposing extending plates 28A, 28A. The directions are respectively laid in parallel with two linear guides 44. In addition, both ends of the air nozzle 36 are via a block 46 and a slide block (nut (nut) The member 48 is supported by the opposing rails 44. In addition, the ball screw 50 is screwed to the slider 4. 8, and one end of the ball screw 5A is coupled to a rotating shaft of a motor 52 which is supported by the extension plate 28A. Further, the controller 18 is based on the winding diameter of the winding coil 34. The rotation speed of the motor 52 is controlled, and the winding diameter of the winding coil 34 is a winding diameter calculated based on a detection signal from the winding direct control sensor. Thereby, as shown in FIGS. 4A and 4B, While maintaining the distance L between the discharge port 36A of the air nozzle 36 and the surface of the winding roll 34 at a predetermined distance, the air nozzle 36 is moved following the change in the winding diameter of the winding roll 34. Fig. 4A is a small winding diameter. 4B is a state in which the winding diameter is thick. The distance L between the discharge port 36A of the air nozzle 36 and the surface of the wound roll 34 is preferably in the range of 2 mm to 15 mm. When the distance l is less than 2 mm, the discharge port 36A has It may come into contact with the surface of the wound roll 34. On the other hand, when the distance L exceeds 15 mm, the pressure when the surface air of the wound roll 34 is pressed cannot sufficiently remove the carried air. Set the dust cover (not shown) The linear guides are used to execute the 18 201228918 40652pif 44 and the block 46) with the ball screw % so that the generated dust does not scatter. In addition, as shown in FIG. 3, the guide roller 54 is preferably included in the turret 22. The mysterious light guide 54 limits the advancement path of the diaphragm 2 so that when the # tower 2 gas is turned, the film that is about to be wound around the wound roll 34 does not come into contact with the air ejection unit 24, especially It will come into contact with the flexible air hose 38B or the moving mechanism 4A of the air introduction line. That is, as shown in Fig. 3, the support arm 56 is extended in a curved shape from the outer side of the extension to the outer side of the emblem. The report 54 is rotatably supported by the front end portion and the center portion of the support arm 56, respectively. Thereby, it is formed that the guiding member 54' is disposed and the air ejection unit 24 is disposed in the advancement path of the film 12 wrapped around the guide roller 54, which is rotated when the turret 22 is rotated. Rotating with the material 22 and wrapping it by the film 12 which is wound around the roll 34. Further, the number of the guide rollers 54 is not limited to two. Further, in Fig. 3, the guide roller 54 is supported by the support arm 56 extending from the extension plate 28A, but the disk-shaped turret may be employed to form the support portion of the guide roller 54. In short, it suffices that the guide roller 54 is also rotated together with the rotation of the turret 22. Thereby, when the turret 22 is rotated, the film 12 wound around the winding roll 34 can be prevented from coming into contact with the air ejecting unit 24. Therefore, the surface of the film 12 is not damaged by contact. Next, the action of the film winding device 10 constructed as described above will be described. As shown in Fig. 5A, in the winding position, the film 12 is wound around the first winding shaft 32A, and the surface of the wound roll 34 is pressed by the air due to the air ejected from the air nozzle %. Thereby, the winding air carried by the 2012 201218 18 40652pif during the advancement of the film 12 is prevented from being caught in the winding roll 34 to cause the winding failure. Next, based on the detection signal from the winding diameter sensor (not shown), after the controller 18 detects that the winding diameter of the wound film 12 has been filled, the controller 18 sends a winding switching command to the film winding. The winding drive control unit 10A of the apparatus 1 and the winding switching drive control unit 16A of the film winding switching device 16 are provided. For example, when the film 12 of 4000 m is wound around the first winding shaft 32A, the controller 18 judges that it has been full by using the winding diameter when it has been wound 38 〇〇m, and issues a winding switching command. . . As shown in FIG. 5C, the winding drive control unit 〇A rotates the turret 22 by 18 G degrees based on the winding switching '=, so that the second winding car at the standby position is n-faced at the winding position, and is full. The winding roll 34 shifts m until the film 12 is fed by the film winding switching device 16; the winding of the film 12 is continued until the winding end is completed (until the winding side is completed). In η, the rotation of the turret 22 for realizing the film winding switching is over the rotation of the turret 2 by the air ejection unit 24 of the It3 working gas nozzle 36. Therefore, the milk squirting unit 24 will With the turret 2 332 =. Therefore, even when the air is pushed by the application method, the Jt day/° 可 can be obtained from the surface of the winding 34 to the second Αβ to the end of the leak. Stop (from 380 〇m to 4000m ^ ^ surface self-proclaimed - _ 乳乳推堡' therefore 'will not be like the previous turret type

S 201228918 4U6^2pif Winding device does not generate a winding failure after the start of winding cutting (that is, at the outer circumference of the winding roller). Moreover, in the embodiment of the present invention, since the guide cymbal 54 is provided with the rotation of the cymbal 22, the winding edge and the 3" thin film 12 are not brought into contact with the air ejection unit 24. The occurrence of scratches, etc. is early. The case will be described with reference to Fig. 5A to Fig. 5C. If the turret 22 is rotated by 9 degrees from the state of Fig. 5A, the actor will be separated. As can be seen from Fig. 5B, before the flexible hose 38B or the moving mechanism 4 is brought into contact with the winding reel 212, the film 54 is wrapped and the turbulence is rotated. Moreover, as shown in Fig. 5C, if the turret 22 is rotated 18 The tanning, 12 is formed on the outside of the flexible hose 38Β or the moving mechanism 4〇 to form a forward path.
