ルに好適なフイルム搬送装置に関する。DETAILED DESCRIPTION OF THE INVENTION (1) Field of Industrial Application The present invention relates to a film transporting device for transporting a flexible film while vacuum suctioning it to a surface thereof, and particularly to a constant speed and constant velocity without sliding on a roll. The present invention relates to a film transport device suitable for a film transport roll that is transported under tension.

等をほどこして、鏡面状のロールが使用されている。(2) Configuration of Conventional Example and Problems Thereof A large number of transport rolls are used in a film transport device such as a polymer film processing device, a film coater, a film inspection device, and a film winder. Conventionally, a transport roll is a mirror-like roll that has been coated with hard chrome to prevent the roll surface shape from being transferred to the transport film and scratching the film.

空吸引孔をもうけた真空吸引形の搬送ロールが使用され
ている。A vacuum suction hole was provided on the roll surface where the tension difference before and after the transport roll was large, where the wrap angle to the transport roll was small, and where the friction between the roll and the film was small and slippage was likely to occur. A vacuum suction type transfer roll is used.

ル間全域にゆき渡らず、期待したフイルム把持力を得ら
れないという問題があった。However, this conventional transport roll, when the film is very smooth or the rigidity of the film is low, and the film adheres to the vicinity of the vacuum suction hole, the vacuum atmosphere is limited to only the vacuum suction hole periphery, There was a problem that the expected film gripping force could not be obtained because the film did not reach the entire area between the film and the roll.

とを目的とするものである。(3) Object of the invention The present invention has been made in view of the above circumstances, and in the above-described film transport apparatus, particularly when film gripping force is required, while gripping the film stably by vacuum suction without slipping. An object of the present invention is to provide a film transport device for transporting.

送装置である。(4) Structure of the Invention The above object is achieved by the present invention described below. That is, according to the present invention, in a transporting device that transports a flexible film while suctioning it to the surface by vacuum suction, a venting material having a large number of three-dimensionally communicating holes is formed so that the communicating material communicates with the vacuum suction holes on the surface. The film transfer device is characterized in that the air between the ventilation member and the flexible film is uniformly exhausted by the exhaust action from the vacuum suction hole.

えることなく搬送できるのである。As described above, in the present invention, since the ventilation member having the three-dimensionally or three-dimensionally a plurality of communication holes which are not closed by the suction of the flexible film is disposed above the vacuum suction hole, the vacuum suction as in the conventional case is performed. The hole is not completely blocked by the sucked film, and thus the expected large gripping force is obtained, and at the same time, the communication hole of the ventilation member is not closed by the flexible film. Since it is a minute item that does not suck into the inside, it can be conveyed without damaging the conveyed film.
上述の本発明は以下に述べるフイルム搬送ロールに特に
好ましくは適用できるものであるが、その他ロボットの
ハンド等にも適用できるものであることはその趣旨より
明らかである。The present invention described above is particularly preferably applicable to the film transport rolls described below, but it is apparent from that point that it is also applicable to other robot hands and the like.
以下本発明の詳細を前述のフイルム用搬送ロールを例に
説明する 第１図（Ａ）は実施例の搬送ロールの構成を示す部分断
面図，第１図（Ｂ）は（Ａ）図のＡ部の拡大図である。The details of the present invention will be described below by taking the above-mentioned film transfer roll as an example. FIG. 1 (A) is a partial cross-sectional view showing the structure of the transfer roll of the embodiment, and FIG. 1 (B) is a part (A) of FIG. It is an enlarged view of a part.

力によって決められ、実験的に決定する必要がある。As shown in FIG. 4, reference numeral 4 denotes a ventilating material according to the present invention, which has three-dimensionally or three-dimensionally a plurality of communication holes communicating with the vacuum suction port 1 and not closed by suction of the flexible film 10 as described above. However, as shown in the drawing, it is preferable from the viewpoint of gripping force and the like that the roll surface is provided with a vacuum suction port so as to cover substantially the entire area. The communicating hole 6 preferably has a large cross-sectional area from the exhaust surface within the range in which it is not closed by the sucked flexible film, but a small cross-sectional area is preferable from the viewpoint of transfer to the film and damage. The hole shape, thickness and material of such a ventilation material are determined by the rigidity of the target film and the necessary gripping force, and must be determined experimentally.

防止される。Particularly for a polymer film which is difficult to handle and is likely to cause transfer and a functional polymer film having a functional film formed thereon, it is preferable that the communication holes have a minute cross-sectional area in which transfer does not occur. The opening cross-sectional area of such a communication hole varies depending on the gripping force and the film rigidity as described above.
When the thickness is not more than μm, the occurrence of transfer is prevented under practical conditions even in the above polymer film having a film thickness of not more than 200 μm.

Woven cloth and sintered metal with a smooth surface can be preferably used. Among them, non-woven fabrics made of polymer materials have a basis weight of 20 to 300 g / m 2 and a thickness of 1 mm or less, and sintered metals have a particle diameter of 100 μm or less in equivalent diameter,
It can be widely applied to conveyance of the polymer film in terms of gripping force and film-damaged surface, and is preferably used.

なきよう固定配設した表面につき、比較を実施した。Hereinafter, the gripping force measurement for explaining the evaluation result of the gripping force of the specific example of the ventilation member 4 will be performed by the gripping force evaluation method shown in FIG.
A comparison was made between a conventional surface, that is, a hard chrome-plated mirror surface having a vacuum suction hole formed therein and a surface on which a ventilation member 4 is fixedly arranged so as not to slip.

That is, the tensiometer 105 was pulled under the condition that the scale was constant, the tension at the point where the film 104 was displaced on the sample plate 103 was measured, and the gripping force was evaluated by this value.

かる。It can be seen from FIG. 4 that with the mirror surface of the conventional example, a large gripping force cannot be expected for a polymer film of 175 μm or less.

In particular, a large gripping force is obtained in a thin film, and it is understood that it is particularly effective for a polymer film having a thickness of 200 μm or less.

送ロールが得られる。In each of the examples, no transfer of the surface shape of the sample plate to the flexible film occurred in the above evaluations.
Therefore, a transport roll suitable for a desired film can be obtained by selecting the above-mentioned ventilation material in consideration of the influence of scratches or the like on the film at the time of slip, the ease of processing, and the maintainability.

It is possible to sufficiently prevent the influence of the connecting line on the quality of the film, but as shown in FIG. 5, in the case of general sticking and pasting, a diagonal joint ((A)
(Fig.), In the case of the thick ventilation member 202, the thickness direction diagonal joint (Fig. (B)) is preferable, and in the case of the thin ventilation member 202,

The film can be effectively spread and held. In particular, it is suitable for a high-speed transport roll whose gripping force is reduced due to the accompanying airflow and a rigid transport roll that firmly transports a film whose influence of gravity cannot be ignored.
