The specific embodiment
With one embodiment of the present invention the present invention is described in more detail.In addition, the present invention is not limited to this embodiment.
Present embodiment is with to adopt wrinkle of the present invention to stretch the manufacturing installation of flat plastic film rolls with cylinder relevant, describes with reference to Fig. 1～Fig. 3.
Fig. 1 stretches flat schematic isometric with cylinder for wrinkle of the present invention.In Fig. 1, wrinkle are stretched flat to be possessed with cylinder 1: the swing roller body 12 that is being supported by axle 11; Overlayed on the fiber body structure 14 on the outer peripheral face 13 of swing roller body 12; Make fiber body structure 14 along the flexible telescoping mechanism 15 of the centre of gration direction of principal axis of swing roller body 12.In addition, but swing roller body 12 also can be with respect to axle 11 by free rotary ground supportings, and perhaps also can being fixed, to support on the axle 11, with axle 11 be S. A..No matter under any situation, in the present embodiment, the center shaft of axle 11 is rotary middle spindle.
The outer peripheral face 13 of swing roller body 12 and fiber body structure 14 rotatably contact with identical speed substantially.Stretch flat lower position 16 with cylinder 1 at wrinkle shown in Figure 1, fiber body structure 14 is stretched by telescoping mechanism 15, and at upper side position 17, fiber body structure 14 is shunk by telescoping mechanism 15.By telescoping mechanism 15, fiber body structure 14 is stretched on the centre of gration direction of principal axis of swing roller body 12, thereby the membranoid substance (not shown) that moves contacting with fiber body structure 14 is paid the tension force of Width.Thus, prevent the generation of the wrinkle on the membranoid substance, perhaps stretched the wrinkle that produce on the flat membranoid substance.
As fiber body structure 14, the material that has retractility in the cloth and silks such as the fabric that use is made of natural fiber or chemical synthetic fiber, knitting, nonwoven fabrics.The knitting of plain stitch, rib construction, purl stitch etc. is realized retractility by the distortion of organizing self.The fabric of plain weave, twill etc. and nonwoven fabrics lack retractility mostly, but by elastic filament or contain fabric and the nonwoven fabrics that the strand of elastic filament constitutes and have retractility.
The seam portion of the cloth and silk of barrel-contoured fiber body structure 14 is stretched flat effect for sometimes membranoid substance quality or wrinkle and is brought harmful effect.Preferably using no seam this moment is that seamless tubular cloth and silk is as fiber body structure 14.As such fiber body structure, preferred especially seamless cylindrical fabric.
Knitting by the fiber of shortage retractilities such as polyamide, polyester, acrylic fibre constitutes owing to have the retractility of being brought by the distortion of organizing self, therefore can be used as fiber body structure 14 and uses.; because by elastic filament or contain the knitting that the strand of elastic filament constitutes; just can realize bigger distortion with less power, can increase the required moment of torsion ground of rotation significantly, bigger set the expanding amount, so more preferably use as fiber body structure 14.In addition, therefore this knitting more preferably uses as fiber body structure 14 owing to have bigger flexibility.
As elastic filament, for example use poly-subunit propylene glycol processing yarn or polyurethane fibre.Wherein, preferably use the polyurethane fibre flexible, that nerve is excellent.Because of polyurethane fibre is not wear-resisting, preferably use with the form of multi-ply construction silks such as single bag core yarn, double-contracting core yarn, core-spun yarn.Wherein, the bag silk on top layer is preferably by the silk that constitutes with the good material (being difficult for producing the material of frictional electrification) of the charged phasic property of the membranoid substance of manufacturing.The core silk uses polyurethane fibre, and the bag silk can prevent the defective by the charged membranoid substance that static caused by the bag core yarn that material very difficult and membranoid substance generation frictional electrification constitutes.For example, when membranoid substance is mylar, preferably use polyester capillaries as the bag silk.
Form the fiber number of the fiber of fiber body structure 14, be preferably 30 daniers (33 dtex)～450 daniers (500 dtex).According to the inventor's understanding, the effect of using thinner fiber to prevent that obviously membranoid substance from producing wrinkle will be got well.But, use the problem that has easy damaged equal strength aspect than the fiber body structure 14 of fine fibre.If also consider intensity, then form the fiber number of the fiber of fiber body structure 14, be preferably 100 daniers (111 dtex)～250 daniers (278 dtex).When using aforesaid bag core yarn, preferably the core silk is 60 daniers (66 dtex)～200 daniers (222 dtex), Bao Siwei 30 daniers (33 dtex)～100 daniers (111 dtex).In this case, can take into account the effect that silk thread intensity and anti-membranoid substance go out wrinkle.
Stretch flat effect in order further to improve wrinkle, the membranoid substance and the coefficient of static friction between the fiber body structure 14 that become object are high more good more.But if coefficient of static friction is too high, then membranoid substance will become the state that is subjected to surpassing the tension force that needs above Width, causes membranoid substance to produce wrinkle sometimes.Therefore, according to the inventor's research, coefficient of static friction is preferably 0.3～0.7.
There is no particular limitation for the material of the outer peripheral face 13 of swing roller body 12.For example, metal can be, also resin or rubber can be.But flexible swimmingly on the centre of gration direction of principal axis of swing roller body 12 in order to make fiber body structure 14, the coefficient of static friction between fiber body structure 14 and the outer peripheral face 13 is preferably lower.Usually, if this coefficient of static friction 0.4 or below it, then can be realized its objective function without a doubt.Preferably select material, the roughness of surface of outer peripheral face 13 to make coefficient of static friction in this scope.
The mensuration of the coefficient of static friction that fiber body structure 14 and cylinder outer peripheral face are 13 is used test piece shown in Figure 8, measures and is undertaken by determinator shown in Figure 9.Overlayed on the centre of gration direction of principal axis of the swing roller body 12 of the fiber body structure 14 on the outer peripheral face 13 of swing roller body 12, be defined as the length direction of fiber body structure 14.From fiber body structure 14, the test piece 81 of long 350mm, wide 50mm is made in cutting.The length direction of test piece 81 is consistent with the length direction of fiber body structure 14.On the both ends of the length direction of test piece 81, be separately installed with adapter plate 83a, 83b, this adapter plate 83a, 83b have hole 82a, the 82b that can install hammer or spring balance.Adapter plate 83a, 83b, the even and skid-resistant mode with Width by for example bolted etc., is installed in the test piece 81.The test piece 81 of these adapter plates 83a, 83b is housed, measures the test specimen 84 of usefulness and be supplied to determinator as coefficient of static friction.
Determinator 91 as shown in Figure 9.Determinator 91 comprises swing roller body 12, hammer 92 and the spring balance 93 that is not being supported revolvably.Being determined as of coefficient of static friction is wound on test specimen 84 on the outer peripheral face 13 that is supported to the swing roller body 12 that can not rotate, and strides across 180 ° on its circumferencial direction.In the hole 82b of a side's of this test specimen 84 adapter plate 83b, hang hammer 92.The weight of hammer 92 is chosen to be, and the weight of adapter plate 83b adds up to 100g with the weight of hammer 92.In the hole 82a of the opposing party's of test specimen 84 adapter plate 83a, hang spring balance 93.
Bottom by controlling spring balance 93, and downwards not influencing result's enough slow speed moving it like that shown in arrow 94, thereby measure.The load that test specimen 84 begins when mobile is measured by spring balance 93.(I) obtains coefficient of static friction according to following formula.
μ＝In(T2/T1)φ (I)
At this, μ is a coefficient of static friction, and T1 serves as reasons and hammers 92 tension force that produce (being 100gf (0.98N) at this) into shape, and T2 is the load of being measured by spring balance 93, and φ is the winding angle (is π rad at this) of test specimen 84, and In is a Napier's logarithm.In addition, mensuration is to be divided into each length of 6 parts according to the girth with the outer peripheral face of swing roller body 12, what carry out except 5 positions at the rotary middle spindle two ends of swing roller body 12.Load T2 measures the aviation value of the load that obtains for each.
Be installed in the mensuration of the coefficient of static friction between the fiber body structure under the state 14 and membranoid substance on the swing roller body 12, also with and the similar method of the mensuration of the coefficient of static friction of 13 of the outer peripheral faces of above-mentioned fiber body structure 14 and swing roller body 12 carry out.Replace the test piece 81 that constitutes by fiber body structure 14 in the aforementioned test specimen 84, from the conveying operation of membranoid substance with fiber body structure 14 contacted membranoid substances on, make the test specimen 104 identical with the test specimen 84 of Fig. 8.
Determinator 101 as shown in figure 10.Determinator 101 comprises that fiber body structure 14, hammer 102 and the spring balance 103 installed in the swing roller body 12 that do not supported revolvably, outer peripheral face 13 ground that are covered this swing roller body 12 constitute.Fiber body structure 14, in Figure 10, the mode that is positioned at the vertical direction top of swing roller body 12 with maximum expanding position is installed on the swing roller body 12.
In Figure 10, mensuration is to be undertaken by the test specimen 104 that is wound on the fiber body structure 14.Test specimen 104 to the winding angle of fiber body structure 14 with and later mensuration order, be that the above-mentioned winding angle illustrated with utilizing Fig. 9 is identical with the mensuration order.In addition, when the membranoid substance of use is indeterminate, the mylar of used thickness 30 μ m.Particularly, used thickness is eastern beautiful (strain) system mylar " Le ミ ラ one " S10 type of 30 μ m.
In the explanation of the mensuration of above coefficient of static friction, as shown in Figure 8, used the test piece 81 of length, but surpassed at the diameter of swing roller body 12 under the situation such as 150mm as 350mm, when being difficult to mensuration, length suitably can be changed with this length.In addition, when the weight of test piece 81 was heavier relatively, the weight that can revise hammer 92 was able to ignore its effect.The mensuration of above-mentioned coefficient of static friction is to be principle in the atmosphere of 25 ℃ of temperature, relative humidity 40%.But situation away from this condition under, can under the temperature running condition of swing roller body 12 under, humidity and other environment carry out obviously by the mensuration of above-mentioned coefficient of static friction for the state that uses in the operation of swing roller body 12.
The leaning angle of the inclination axle collar preferably can change its setting arbitrarily.By constituting in this wise, can correspondingly change leaning angle with the thickness of the membranoid substance of stretching flat object as wrinkle or width, tension force, can suitably adjust wrinkle and stretch flat effect.
In the present invention, used the fiber body structure 14 that contacts with membranoid substance.Therefore this fiber body structure 14 has retractility because of its surface, with the softness that contacts of membranoid substance, when existing under the situation of foreign matter, can prevent that foreign matter from pushing membranoid substance tough in the operation process, is difficult for producing the damage to the membranoid substance surface.Fiber body structure 14 is chosen to be easily and compares lightweight with other mechanisms and have the appropriateness friction with respect to membranoid substance.At this moment, it is little to rotate required moment of torsion, is difficult for producing velocity contrast with membranoid substance, therefore seldom can cause damage to the surface of membranoid substance because of slip.Fiber body structure 14 usually has aeration.Therefore, even enter air between the membranoid substance of plastic sheeting etc. and cylinder, it also can not rest on herein, is easy to discharge.Therefore, the high adherence of membranoid substance and fiber body structure 14 can be kept, even and appropriate friction can be stably kept between the two.According to this specific character, the conveying cylinder that uses in the coiling process as the plastic sheeting manufacturing in that to use wrinkle of the present invention to stretch flat when use cylinder, just no longer needs the groove of design-calculated air escape usefulness in the past sometimes on conveying cylinder.
Fig. 5 for the explanation wrinkle stretch flat with the fiber body structure 14 in the cylinder 1 maximum expanding position and the instruction diagram to the relation of the cornerite of fiber body structure 14 of membranoid substance 53.In Fig. 5, maximum expanding position 51, be to make position on the hand of rotation that fiber body structure 14 stretches to greatest extent by telescoping mechanism 15, maximum collapse position 52 is to make position on the hand of rotation that fiber body structure 14 shrinks to greatest extent by telescoping mechanism 15.The wrap angle of membranoid substance 53 is preferably in 30 ° or more than it.Stretch flat effect in order to embody wrinkle better, wrap angle is above, the expanding angle beta of 120 ° or its or below it more preferably.At this, the expanding angle beta is, in plane perpendicular to S. A., and rotary middle spindle, maximum expanding position 51 and maximum collapse position 52 angulations.Use under the mode of the inclination axle collar at telescoping mechanism 15, the width angle beta is generally 180 °, uses under the mode of actuator at telescoping mechanism 15, and the width angle beta can be made as angle arbitrarily usually.Setting angle α is that in the plane perpendicular to rotary middle spindle, rotary middle spindle, maximum width expanding position 51 and membranoid substance 53 leave the some angulation of fiber body structure 14.For fear of temporarily being shunk by the membranoid substance 53 of expanding, setting angle α is preferably at 0 ° or more than it, but as long as at-45 ° or more than it, all no problem mostly in the practicality.
The wrinkle of membranoid substance of the present invention are stretched the flat cylinder of use, owing to prevent that the effect of membranoid substance generation wrinkle is better, so are preferably on the manufacturing installation of plastic sheeting of membranoid substance to the strictness of wrinkle quality requirements, for example optical applications and use.
Fig. 2 is the scheme drawing of the Fabrication procedure of general plastic sheeting.The molten polymer of thermoplastic base resin, being shaped from sheet is extruded into sheet continuously with ozzle 21.The molten sheet of extruding contacts with drum cooler 22, becomes the film 23 of cooling curing.Film 23 is imported in the extension apparatus 24 continuously.Film 23 is extended on length direction and Width in extension apparatus 24.Film 25 after the extension is carried to batch up gear 27 by conveying cylinder 26a, 26b, in batch up gear 27, is coiled into web-like.The film that coils into web-like forms film rolling (membranoid substance volume) 28.In batch up gear 27,, be equipped with respect to the film rolling 28 in forming and press cylinder 29 with the rotation of the pressure contact of regulation in order to form film rolling 28 well.
The film rolling 28 of manufacturing is also dispatched from the factory as goods with this state sometimes, but when the width of the film rolling 28 of manufacturing is longer, is provided for cutting action as intermediate 30 usually.
In cutting action, the film 31 from middle goods 30 pull straight is delivered to cutting machine 33 by conveying cylinder 32a, 32b.In cutting machine 33, film 31 is cut into the width of regulation, becomes a plurality of films.A plurality of films are batched by separately batch up gear 34 respectively, form the film rolling (membranoid substance volume) 35 as end article.In batch up gear 34,, be equipped with respect to the film rolling 35 in forming and press cylinder 36 with the rotation of the pressure contact of regulation in order to form film rolling 35 well.
As conveying cylinder 26a, 26b, 32a, the 32b in the Fabrication procedure of film rolling shown in Figure 2, can use the wrinkle of membranoid substance of the present invention to stretch the flat cylinder of using as required.In addition, press cylinder 29,36, also can use the wrinkle of membranoid substance of the present invention to stretch the flat cylinder of using as required as rotation.
Film rolling 28 or film rolling 35 are provided for the operation of accepting predetermined process in the decompression atmosphere gas of vacuum deposition apparatus etc. sometimes.In this operation, carry by conveying cylinder from the film that film rolling 28,35 is pulled out, after having accepted predetermined process, batched.In this operation, must carry out the wrinkle of film sometimes and stretch flat.In this operation, for example, when the wrinkle in the past that constitute at the spreading roller that adopts by flexure type are stretched the flat-bed machine structure, enter cylinder surface and compare very little with the situation in the atmosphere with the influence of following air-flow between the film.At this moment, the friction coefficient between cylinder and film becomes big.Generate wrinkle on the film in order to prevent that this friction coefficient increase from causing, need critically adjust the rotative speed of cylinder.In addition, owing at the Width of film superfluous tension force takes place easily, film is impaired easily thus.
Relative therewith, stretching the flat-bed machine structure as the wrinkle in the operation in the atmosphere gas that is placed in decompression, use wrinkle of the present invention to stretch and put down when using cylinder, because the retractility or the flexibility of fiber body structure, small velocity contrast is absorbed, be difficult for to generate relative speed difference, and the tension force of the surplus that produces on the thin-film width direction can absorb by the infinitesimal deformation of fiber body structure, therefore above-mentioned wrinkle in the past can not take place stretch unfavorable condition in the flat-bed machine structure.
The sectional elevation of the film batch up gear when Fig. 3 uses as the crimping cylinder for wrinkle of the present invention being stretched flat usefulness cylinder.When the plastic sheeting 37 that will transport coils into web-like as film rolling (membranoid substance volume) 38, will be by swing roller body 12, overlayed on membranoid substance wrinkle of the present invention that fiber body structure 14 on the outer peripheral face 13 of swing roller body 12 and telescoping mechanism 15 constitute and stretch and flatly be crimped on the film rolling 38 formation film rolling 38 with cylinder 1.
In the Fabrication procedure of plastic sheeting shown in Figure 2, for crimping cylinder 29 being housed on batch up gear 27 or batch up gear 34 or pressing cylinder 36, pay contact pressure for film rolling 28,35 by crimping cylinder 29,36 on one side, batch the film batch up gear of film 25,31 on one side, by membranoid substance wrinkle of the present invention shown in Figure 3 are stretched flat with cylinder application in crimping cylinder 29,36, can shorten wrinkle stretched the film of having put down not by the length of the free path of walking with controlling.Therefore, can prevent that wrinkle from stretching flat film and relaxing once more, can prevent that thus film from giving birth to wrinkle once more.
