Description

フィルムを横延伸するためのテンター装置において、フィルムの両端を把持するフィルム把持手段に関する。   The present invention relates to a film gripping means for gripping both ends of a film in a tenter device for transversely stretching the film.

二軸延伸ポリエステルフィルムなどのフィルムの製造装置としては、口金からシート状に吐出してキャストドラム上で冷却固化した未延伸フィルムを、縦延伸機でフィルムの搬送方向に延伸した後、テンター装置でフィルムの幅方向に延伸する逐次二軸延伸法や、前記未延伸フィルムをテンター装置でフィルムの搬送方向とフィルムの幅方向とに延伸する同時二軸延伸法などが知られている。   As an apparatus for producing a film such as a biaxially stretched polyester film, an unstretched film that has been discharged from a die into a sheet and cooled and solidified on a cast drum is stretched in the film transport direction by a longitudinal stretching machine, and then a tenter apparatus. A sequential biaxial stretching method in which the film is stretched in the width direction of the film and a simultaneous biaxial stretching method in which the unstretched film is stretched in the film transport direction and the film width direction by a tenter device are known.

これらの製造方法に用いられるテンター装置は、フィルムの両端を把持するフィルム把持手段、及び、フィルムに熱風を吹き付けてフィルムの熱処理を行うフィルム熱処理手段、及び、フィルム把持手段にオイルを供給するオイル供給手段を有している。また、フィルム把持手段は、フィルムを把持するクリップチェーン及びカバー手段及びレール手段及び駆動手段とを有している。   The tenter apparatus used in these manufacturing methods includes a film gripping means for gripping both ends of the film, a film heat treatment means for performing heat treatment of the film by blowing hot air on the film, and an oil supply for supplying oil to the film gripping means Have means. The film gripping means has a clip chain for gripping the film, cover means, rail means, and drive means.

このようなテンター装置はこれまで種々のものが提案されてきた。   Various such tenter devices have been proposed so far.

特許文献１では、クリップチェーンを個別に冷却する構造が開示されている。特許文献２では、幅可変ノズルによりフィルム把持手段に熱風があたらないようにする構造が開示されている。   Patent Document 1 discloses a structure for individually cooling clip chains. Patent Document 2 discloses a structure that prevents hot air from being applied to the film gripping means by a variable width nozzle.

特開平２−１８２６５４号公報Japanese Patent Laid-Open No. 2-182654 特開２０１２−２１１７３１号公報JP 2012-211731 A

前記特許文献１に記載の発明は、フィルムを把持するクリップチェーンを冷却することにより、クリップチェーンに供給されたオイルは温度低下し、温度低下に伴い粘度が上昇し小さな粒で飛び散ることが少なくなったが、むしろ大きな粒で飛び散ってしまうという問題があった。   In the invention described in Patent Document 1, by cooling the clip chain that grips the film, the temperature of the oil supplied to the clip chain decreases, the viscosity increases as the temperature decreases, and it is less likely that the oil is scattered in small particles. However, there was a problem that it was rather scattered with large grains.

前記特許文献２に記載の発明は、幅可変ノズルから噴出された熱風がフィルム把持手段に直接あたらないが、幅可変ノズル端部から噴出された熱風がフィルムに強くあたりその後カバー手段の中に入り、その後レール手段の屈曲部においてクリップチェーンに供給されたオイルミストと共にカバー手段の外に出てくるという問題があった。

In the invention described in Patent Document 2, the hot air blown from the variable width nozzle does not directly hit the film gripping means, but the hot air blown from the end of the variable width nozzle hits the film and then enters the cover means. Then, there is a problem that the bent part of the rail means comes out of the cover means together with the oil mist supplied to the clip chain.

The film 2 is heated to a predetermined temperature, and hot air heated to a temperature suitable for stretching is blown onto the film 2 in the stretching zone 15, so that the film 2 is stretched after being heated to a temperature suitable for stretching. By blowing hot air heated to a temperature suitable for heat fixation onto the film 2, the film 2 is heat-fixed by heating to a temperature suitable for heat fixation. The film gripping means 3 grips the film 2 at the entrance of the film heat treatment means 4, and then opens the film 2 at the exit through the plurality of bent portions 6 of the gripping path 5 in the film heat treatment means 4. The return route 10 is returned to the entrance. In the return path 10, it is desirable that the film grip means 3 has a cover means so that the hot air for preheating, stretching and heat setting of the film heat treatment means 4 does not hit the film gripping means 3. It is desirable that the cover means of the return path 10 is a closed system and is insulated and has cooling air supply means and cooling air exhaust means. It is desirable that the gripping path 5 also has a cover means on the film grip means 3 so that the hot air from the film heat treatment means 4 does not hit the film gripping means 3. Since the film 2 is gripped, it cannot be a closed system, but it is desirable to enclose it as much as possible.

図４においてフィルム２は、フィルム熱処理手段４の入り口でフィルム把持手段３により両端を把持され、フィルム熱処理手段４の予熱ゾーン１４で所定の温度に加熱した熱風をフィルム２に吹き付けることでフィルム２は所定の温度に加熱され、延伸ゾーン１５では延伸に適した温度に加熱した熱風をフィルム２に吹き付けることで、フィルム２は延伸に適した温度に加熱された上で延伸され、熱固定ゾーン１６では熱固定に適した温度に加熱した熱風をフィルム２に吹き付けることで、フィルム２は熱固定に適した温度に加熱され熱固定される。フィルム把持手段３はフィルム熱処理手段４の入り口でフィルム２を把持後、フィルム熱処理手段４内の把持経路５の複数の屈曲部６を通って出口でフィルム２を開放し、フィルム熱処理手段４の外側のリターン経路１０を通って入り口に戻る。リターン経路１０ではフィルム把手段３に外の空気があたらないようにカバー手段を有することが望ましい。リターン経路１０のカバー手段は密閉系でかつ断熱し冷却用冷風の供給手段と冷風の排気手段とを有していることが望ましい。把持経路５もフィルム把手段３にフィルム熱処理手段４の熱風がフィルム把持手段３にあたらないようにカバー手段を有することが望ましい。フィルム２を把持しているために密閉系にはできないが、可能な限り囲うことが望ましい。   In FIG. 4, the film 2 is held at both ends by the film holding means 3 at the entrance of the film heat treatment means 4, and the film 2 is blown by hot air heated to a predetermined temperature in the preheating zone 14 of the film heat treatment means 4. The film 2 is heated to a predetermined temperature, and hot air heated to a temperature suitable for stretching is blown onto the film 2 in the stretching zone 15, so that the film 2 is stretched after being heated to a temperature suitable for stretching. By blowing hot air heated to a temperature suitable for heat fixation onto the film 2, the film 2 is heated to a temperature suitable for heat fixation and heat fixed. The film gripping means 3 grips the film 2 at the entrance of the film heat treatment means 4, then opens the film 2 at the exit through the plurality of bent portions 6 of the gripping path 5 in the film heat treatment means 4, and the outside of the film heat treatment means 4. The return route 10 is returned to the entrance. In the return path 10, it is desirable to have cover means so that outside air does not hit the film grip means 3. It is desirable that the cover means of the return path 10 is a closed system and is insulated and has cooling air supply means and cooling air exhaust means. It is desirable that the gripping path 5 also has a cover means on the film grip means 3 so that the hot air from the film heat treatment means 4 does not hit the film gripping means 3.

図１、２は、本発明のテンター装置１のフィルム把持手段の屈曲部の概略断面図である。   1 and 2 are schematic cross-sectional views of the bent portion of the film gripping means of the tenter device 1 of the present invention.

図１は、リターン経路１０がテンター装置１の内部を通る構成を示しており、図３のテンター装置の断面図である。この場合テンター装置１は、フィルム把持手段３の把持経路５とリターン経路１０とが隣接しているが、把持経路５とリターン経路１０との間で内部の風が行き来しない構造であることが望ましい。排気手段８は把持経路５の把持経路カバー手段７に接続され、固定配管１８とフレキシブルダクト９とフィルタ１９からなることが望ましい。またリターン経路１０は断熱カバー１７により断熱され、図示しない冷却手段により中のクリップチェーン１２が冷却されることが望ましい。クリップチェーン１２のベアリング１３には図示しないオイル供給手段によりオイルが供給される。１ヶ所の排気手段から排気される排気風量は５Nm３／ｍｉｎ〜１０Nm３／ｍｉｎが望ましく、内径φ８０ｍｍの配管として風速は１７ｍ／ｓｅｃ〜３４ｍ／ｓｅｃが望ましい。 FIG. 1 shows a configuration in which the return path 10 passes through the inside of the tenter device 1, and is a cross-sectional view of the tenter device of FIG. In this case, the tenter device 1 desirably has a structure in which the grip path 5 of the film gripping means 3 and the return path 10 are adjacent to each other, but the internal wind does not travel between the grip path 5 and the return path 10. . The exhaust means 8 is connected to the grip path cover means 7 of the grip path 5 and preferably comprises a fixed pipe 18, a flexible duct 9 and a filter 19. Further, it is desirable that the return path 10 is insulated by a heat insulating cover 17 and the inside clip chain 12 is cooled by a cooling means (not shown). Oil is supplied to the bearing 13 of the clip chain 12 by an oil supply means (not shown). 1 exhaust air volume exhausted from the exhaust means places the 5Nm 3 / min~10Nm 3 / min is desirable, wind speed as the pipe internal diameter φ80mm is preferably 17m / sec~34m / sec.

図２は、リターン経路１０がテンター装置１の外部を通る構成を示しており、図４のテンター装置１の断面図である。この場合テンター装置１は、リターン経路１０と把持経路５とは完全に分離されている。排気手段８は把持経路５の把持経路カバー手段７に接続され、固定配管１８とフレキシブルダクト９とフィルタ１９からなることが望ましい。またリターン経路１０は断熱カバー１７により断熱され、図示しない温度調整手段により中のクリップチェーン１２が温度調整されることが望ましい。１ヶ所の排気手段８から排気される排気風量は５Nm３／ｍｉｎ〜２０Nm３／ｍｉｎが望ましく、内径φ１４０ｍｍの配管として風速は５．５ｍ／ｓｅｃ〜２２ｍ／ｓｅｃが望ましい。 FIG. 2 shows a configuration in which the return path 10 passes outside the tenter device 1, and is a cross-sectional view of the tenter device 1 of FIG. In this case, in the tenter device 1, the return path 10 and the grip path 5 are completely separated. The exhaust means 8 is connected to the grip path cover means 7 of the grip path 5 and preferably comprises a fixed pipe 18, a flexible duct 9 and a filter 19. The return path 10 is preferably insulated by a heat insulating cover 17, and the temperature of the clip chain 12 inside is desirably adjusted by a temperature adjusting means (not shown). 1 exhaust air volume exhausted from the exhaust unit 8 of places is 5Nm 3 / min~20Nm 3 / min is desirable, wind speed as the pipe internal diameter φ140mm is preferably 5.5m / sec~22m / sec.

図１、３に示すテンター装置１の場合、テンター装置１自体を小型化することが可能であるが、リターン経路１０を冷却する必要がある。   In the case of the tenter device 1 shown in FIGS. 1 and 3, the tenter device 1 itself can be reduced in size, but the return path 10 needs to be cooled.

一方図２、４に記載のテンター装置１の場合、図１、３に示すテンター装置１と同じ幅のフィルム２を製造する場合であっても、センター装置１自体の大きさが大きくなる。しかしリターン経路１０の冷却は必須ではなく、所定の温度にコントロールする程度でよい。   On the other hand, in the case of the tenter device 1 shown in FIGS. 2 and 4, even when the film 2 having the same width as that of the tenter device 1 shown in FIGS. However, the cooling of the return path 10 is not essential, and may be controlled to a predetermined temperature.

図５、６はフィルム２の平面図を示す。図５は、従来のテンター装置１で製造したフィルム２の製品にはベアリング１３に供給されたオイルがベアリングの遠心力などにより吹き飛ばされ付着しオイル欠点１１となる。図６は、本発明のテンター装置１で製造したフィルム２の製品にはベアリング１３に供給されたオイルの付着は無い。   5 and 6 are plan views of the film 2. In FIG. 5, oil supplied to the bearing 13 is blown off and adhered to the product of the film 2 manufactured by the conventional tenter apparatus 1 due to the centrifugal force of the bearing, and the oil defect 11 is formed. FIG. 6 shows that the oil supplied to the bearing 13 does not adhere to the product of the film 2 manufactured by the tenter device 1 of the present invention.

１ヶ所の排気手段８から排気される排気風量は、５Nm３／ｍｉｎ未満であると排気効果が少なく、オイル欠点を無くすことができない。また１ヶ所の排気手段８から排気される排気風量は、２０Nm３／ｍｉｎを越えるとテンター装置１の風量バランスが崩れてしまうのでこれ以上上げることはできない。
If the amount of exhaust air exhausted from one exhaust means 8 is less than 5 Nm 3 / min, the exhaust effect is small and oil defects cannot be eliminated. Further, if the amount of exhaust air exhausted from one exhaust means 8 exceeds 20 Nm 3 / min, the air amount balance of the tenter device 1 is lost, and cannot be increased any more.
