ルに好適なフィルム搬送装置に関する。Detailed Description of the Invention (1) Industrial Application Field The present invention relates to a film conveying device that conveys a flexible film while vacuum suctioning the surface thereof, and in particular, the present invention relates to a film conveying device that conveys a flexible film while vacuum suctioning the surface thereof. The present invention relates to a film transport device suitable for film transport rolls that are transported under tension.
（２） 従来例の構成とその問題点 高分子フィルム加工装置、フィルムコーター。(2) Configuration of conventional example and its problems Polymer film processing equipment, film coater.
フィルム検査装置、フィルム巻取機等のフィルム搬送装
置は、多くの搬送ロールが使用される。Film transport devices such as film inspection devices and film winding machines use many transport rolls.
搬送ロールは、従莱、搬送するフィルムにロール表面形
状が転写したり、フィルムに傷を与えたりするのを防ぐ
ため、硬質クロムメッキ等をほどこして、鏡面状のロー
ルが使用されている。The transport rolls are mirror-finished rolls that are coated with hard chrome plating or the like to prevent the surface shape of the roll from being transferred to the film being transported and from scratching the film.
そして、搬送ロール前後の張力差が大きい所、搬送ロー
ルへの巻掛角が小さな所、ロールとフィルムとの摩擦が
小さく、スベリを発生しそうな所には、ロール表面に真
空吸引孔をもうけた真空吸引型の搬送ロールが使用され
ている。Vacuum suction holes are provided on the roll surface in areas where there is a large tension difference between the front and rear of the transport roll, where the winding angle to the transport roll is small, and where the friction between the roll and film is small and slippage is likely to occur. A vacuum suction type conveyor roll is used.
しかしながら、この従来の搬送ロールは、フィルムが非

、真空吸引孔付近にフィルムが密着する場合、真空雰囲
気が真空吸引孔周囲だけに限定され、フィルムとロール
間全域にゆき渡らず、期待したフィルム把持力を得られ
ないという問題があった。However, with this conventional conveyor roll, if the film is very smooth or has low rigidity and the film is in close contact with the vicinity of the vacuum suction hole, the vacuum atmosphere is limited to the area around the vacuum suction hole. There was a problem in that the expected film gripping force could not be obtained because it did not spread over the entire area between the film and the roll.
（３発明の目的
本発明は、かかる現状に鑑みなされたもので上述したフ
ィルム搬送装置に於いて、特にフィルム把持力を必要と

とを目的とするものである。(3. Purpose of the Invention The present invention was made in view of the current situation, and in the above-mentioned film conveyance device, when a film gripping force is particularly required, the film can be conveyed while stably gripping it without slipping by vacuum suction. The object of the present invention is to provide a film conveying device that does the following.

送装置である。(41 Structure of the Invention The above object is achieved by the present invention as described below. That is, the present invention provides a conveying device that conveys a flexible film while sucking it to the surface by vacuum suction. A ventilating material having a ventilating material is disposed on the surface so that the communication hole communicates with the vacuum suction hole on the surface, and the air between the ventilating material and the flexible film is removed by the exhaust action from the vacuum suction hole. This is a film transport device characterized by uniform exhaustion.

されない換言すれば可撓性フィルムをその中まで吸引し
ない微小なものであるので搬送するフィルムに損傷を与
えることなく搬送できるのである。As mentioned above, in the present invention, a ventilation material having three-dimensional, that is, a large number of communication holes that are not closed by the suction of a flexible film is disposed above the vacuum suction hole, so that the vacuum suction cannot be performed as in the conventional case. The holes are not completely blocked by the suctioned film, so a large gripping force as expected can be obtained, and at the same time, the communicating holes of the ventilation material are not closed by the flexible film. Since the film is so small that it does not get sucked into it, it can be transported without damaging the film being transported.
上述の本発明は以下に述べるフィルム搬送ロールに特に
好ましく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 roll described below, but it is clear from the gist 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ィ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 explained below using the above-mentioned film transport roll as an example. Fig. 1 (A) is a partial sectional view showing the structure of the transport roll of the embodiment, and Fig. 1 (B) is FIG.
図の１がロール本体５に穿設された真空吸引孔、２は搬
送ロール内を真空に保つための排気管、３は気密を保つ
ための回転シールであり、この基本構成は従来の真空吸
引型搬送ロールと同じである。In the figure, 1 is a vacuum suction hole drilled in the roll body 5, 2 is an exhaust pipe to maintain a vacuum inside the conveyor roll, and 3 is a rotary seal to maintain airtightness.This basic configuration is similar to the conventional vacuum suction hole. It is the same as the mold conveyor roll.
図の４が本発明に係わる通気材で、前述の通り、真空吸
引口１に連通し、可撓性フィルム１０の吸引により閉鎖
されない多数の連通孔を立体。4 in the figure shows the ventilation material according to the present invention, which, as described above, has a large number of communicating holes that communicate with the vacuum suction port 1 and are not closed by the suction of the flexible film 10.

ィルムへの転写、損傷等の面からは小断面積が好ましい
、かかる通気材の孔形状；厚み及び材料は対象とするフ
ィルムの剛性及び必要な把持力によって決められ、実験
的に決定する必要がある。As long as it has a target or three-dimensional shape, it is acceptable, but as shown in the figure, it is preferable to arrange it so as to cover almost the entire surface of the roll provided with the vacuum suction port, from the viewpoint of gripping force, etc.
In addition, the larger the cross-sectional area of the communication hole 6 is, the better, as long as it is not blocked by the above-mentioned suctioned flexible film from the exhaust surface, but from the viewpoint of transfer to the film, damage, etc., a small cross-sectional area is preferable. The pore shape of the material; the thickness and material are determined by the rigidity of the target film and the required gripping force, and must be determined experimentally.
特に取扱いが難しく、転写の発生し易い高分子フィルム
及びその上に機能性膜を形成した機能性高分子フィルム
に対しては連通孔が転写の発生しない微小な断面積とす
ることが好ましい。In particular, for polymer films that are difficult to handle and are susceptible to transfer, and for functional polymer films on which a functional film is formed, it is preferable that the communicating holes have a minute cross-sectional area that prevents transfer.
かかる連通孔の開口断面積は前述の通り把持力及びフィ
ルム剛性によって変化するが、１００μｍ以下にするこ
とにより、膜厚２００μｍ以下の上記高分子フィルムに
おいても実用的な条件下で転写の発生が防止される。As mentioned above, the opening cross-sectional area of the communication hole changes depending on the gripping force and film rigidity, but by setting it to 100 μm or less, the occurrence of transfer can be prevented under practical conditions even in the above-mentioned polymer film with a film thickness of 200 μm or less. be done.
以上の点及び入手の容易性の点から、通気材４としては

。The vacuum valve 106 adjusts the evacuation, and the vacuum gauge 107 maintains the degree of vacuum, that is, its scale, by pulling the tension gauge 105 and placing the film 104 on the sample plate 103.
The tension at the point where it shifted was measured, and the gripping force was evaluated based on this value.

レート（ＰＥＴ）フィルムを用いた。Note that a polyethylene terephthalate (PET) film was used as the flexible film 104.
第４図より従来例の鏡面では、１７５μｍ以下の高分子
フィルムに対しては大きな把持力が期待できないことが
わかる。From FIG. 4, it can be seen that the mirror surface of the conventional example cannot be expected to have a large gripping force for a polymer film of 175 μm or less.

な把持力が得られており、２００μｍ以下の高分子フィ
ルムに特に有効なことがわかる。On the other hand, in the example provided with the ventilation material, the gripping force is several times higher than that of the conventional example. In particular, a large gripping force was obtained in the case of a thinner film, and it can be seen that it is particularly effective for polymer films of 200 μm or less.
なお、いずれの実施例も上記評価においてはサンプル板
