Description

ターンバーTurn bar
　本発明は、ターンバーに関し、詳細には、長尺フィルム等のウェブを非接触でガイドするターンバーに関する。 The present invention relates to a turn bar, and more particularly to a turn bar that guides a web such as a long film in a non-contact manner.
　上流側のロールから連続的に送出されたウェブを、所定経路に沿って搬送しながら処理し、下流側のロールに巻き取る処理方式が知られている。このような処理工程では、ウェブは、巻送りロール、ガイドロール、巻取りロール等の多くのロールによって規定される経路に沿って搬送されながら、印刷、ラミネート、乾燥、裁断等の処理等を受ける。 A processing method is known in which a web continuously fed from a roll on the upstream side is processed while being conveyed along a predetermined path and wound on a roll on the downstream side. In such processing steps, the web is subjected to processing such as printing, laminating, drying, cutting and the like while being conveyed along a path defined by many rolls such as a winding roll, a guide roll, and a winding roll. .
　これらのロールの多くは、金属製あるいはゴム製であり、ウェブは、これらロールの表面と接触しながら搬送されることになる。このため、これらロールから離脱したパーティクルがウェブに転写され、ウェブから製造される最終製品の品質を低下させるという問題があった。 Most of these rolls are made of metal or rubber, and the web is conveyed while being in contact with the surface of these rolls. For this reason, there has been a problem that the particles detached from these rolls are transferred to the web and the quality of the final product manufactured from the web is lowered.
　さらに、搬送中のウェブとロールとの速度差、ウェブに作用する張力、ウェブとロールの間の摩擦力により、ウェブに傷、折れシワ、伸び等が生じ、最終製品の歩留まりを低下させるという問題もあった。そして、このような問題は、搬送経路上でウェブの搬送方向を反転させるターンバーの部分で顕著であった。 In addition, the web is damaged, wrinkled, stretched, etc. due to the speed difference between the web and the roll being transported, the tension acting on the web, and the frictional force between the web and the roll, reducing the yield of the final product. There was also. And such a problem was remarkable in the part of the turn bar which reverses the conveyance direction of a web on a conveyance path | route.
　このような問題に対処するため、空気膜を利用した非接触式のガイドロール（ターンバー）が提案されている（特許文献１）。この特許文献１のガイドロールでは、表面に多数の気体噴出孔が形成された中空体の内部に加圧気体を流入させることにより、中空体の表面の気体噴出孔から気体を噴出させ、長尺状フィルムを中空体の外周面に沿って非接触で支持し、長尺状フィルムの搬送経路を反転させている。 In order to cope with such a problem, a non-contact type guide roll (turn bar) using an air film has been proposed (Patent Document 1). In the guide roll of this patent document 1, the gas is ejected from the gas ejection holes on the surface of the hollow body by allowing the pressurized gas to flow into the inside of the hollow body having a large number of gas ejection holes formed on the surface. The film-like film is supported in a non-contact manner along the outer peripheral surface of the hollow body, and the transport path of the long film is reversed.
特開平８－２４５０２８号公報JP-A-8-245028
　上記ガイドロール（ターンバー）は、非接触で長尺状フィルムを反転させることができる等の長所を有しているが、機械加工で噴出孔を形成する場合には、噴出孔の径が大きくなるため、噴出孔の直上と周辺での圧力差が大きくなる。この結果、ウェブがバタツキ易くなり、ウェブを安定して支持できなくなる等の問題が発生している。また、レーザ加工で噴出孔を形成する場合には、製造コストが高くなるという問題が発生している。 The guide roll (turn bar) has the advantage that the long film can be reversed without contact, but when the ejection hole is formed by machining, the diameter of the ejection hole is increased. For this reason, the pressure difference between directly above and around the ejection hole increases. As a result, there is a problem that the web is easily fluttered and the web cannot be stably supported. In addition, when the ejection holes are formed by laser processing, there is a problem that the manufacturing cost increases.
　本発明はこのような点に鑑みてなされたものであり、低い製造コストでありながらウェブを安定して支持できるターンバーを提供することを目的としている。 The present invention has been made in view of these points, and an object of the present invention is to provide a turn bar that can stably support a web at a low manufacturing cost.
　本発明によれば、
　ウェブ状のワークを非接触でガイドするターンバーであって、
　多孔質体で構成された円筒状のロール本体と、
　前記ロール本体の外表面からエアを吐出させるエア吐出機構と、を備え、
　前記ロール本体が、軸線方向端面同士が連結された複数の筒状多孔質体によって構成されている、
　ことを特徴とするターンバーが提供される。 According to the present invention,
A turn bar for guiding a web-like workpiece in a non-contact manner,
A cylindrical roll body composed of a porous body;
An air discharge mechanism for discharging air from the outer surface of the roll body,
The roll body is composed of a plurality of cylindrical porous bodies whose axial end faces are connected to each other,
A turn bar is provided.
　このような構成によれば、ウェブを非接触で支持するロール本体として、全体に微細な孔を有している多孔質体が利用されるので、ロール本体の外周面全体から均一に加圧気体を確実に噴出させることが可能であり、且つ、気体を噴出させる孔を加工により形成する工程が不要となる。 According to such a configuration, since a porous body having fine pores as a whole is used as the roll body that supports the web in a non-contact manner, the pressurized gas is uniformly distributed from the entire outer peripheral surface of the roll body. Can be reliably ejected, and a step of forming a hole for ejecting gas by machining is not necessary.
　本発明の他の好ましい態様によれば、
　前記エア吐出機構が、外周面に前記円筒状のロール本体が取付けられている中空シャフトを備え、
　前記筒状多孔質体が、隣接する筒状多孔質体と接着により接合され、隣接する前記筒状多孔質体との接合部近傍の内周面に凹部を有している。 According to another preferred embodiment of the invention,
The air discharge mechanism includes a hollow shaft having the cylindrical roll body attached to an outer peripheral surface;
The cylindrical porous body is bonded to an adjacent cylindrical porous body by bonding, and has a concave portion on the inner peripheral surface in the vicinity of a bonded portion with the adjacent cylindrical porous body.
　製造工程においてロール本体を構成する筒状多孔質体同士を接着剤で接合する際、接合部分からはみ出した余剰な接着剤が、ウェブ支持面となる筒状多孔質体の表面側に流出すると、ウェブ支持面からの加圧エアの吹出しが阻害される等して、ウェブ支持に支障をきたすことになる。 When joining the cylindrical porous bodies constituting the roll body in the manufacturing process with an adhesive, when the excess adhesive that protrudes from the bonded portion flows out to the surface side of the cylindrical porous body that becomes the web support surface, The support of the web is hindered, for example, the blowing of pressurized air from the web support surface is hindered.
　しかしながら、上記のような構成によれば、筒状多孔質体同士を接着剤で接合する際、接着剤が、隣接する筒状多孔質体との接合部近傍の内周面に設けられた凹部に収容されるため、凹部内の接着剤により、筒状多孔質体がロール本体に対してより強固に接合されている。 However, according to the above configuration, when the cylindrical porous bodies are bonded to each other with the adhesive, the adhesive is provided on the inner peripheral surface in the vicinity of the bonded portion with the adjacent cylindrical porous body. Therefore, the cylindrical porous body is more firmly bonded to the roll body by the adhesive in the recess.
　本発明の他の好ましい態様によれば、
　前記凹部が、前記筒状多孔質体の内周面で円周方向に延びる環状溝を構成している。 According to another preferred embodiment of the invention,
The said recessed part comprises the annular groove extended in the circumferential direction on the internal peripheral surface of the said cylindrical porous body.
　本発明の他の好ましい態様によれば、
　一の筒状多孔質体の他の筒状多孔質体と接合されている軸線方向端面と、前記他の筒状多孔質体の前記一の筒状多孔質体と接合されている端面とが、相補的な凹凸形状を備えている。 According to another preferred embodiment of the invention,
An axial end surface joined to another cylindrical porous body of one cylindrical porous body, and an end surface joined to the one cylindrical porous body of the other cylindrical porous body , Complementary uneven shape is provided.
　このような構成によれば、筒状多孔質体同士の接合部分において径方向の強度が増大し、接続された筒状多孔質体によって構成されるロール本体に中空シャフトからの加圧気体による力が作用しても、ロール本体が接続部分で破損することが回避される。 According to such a configuration, the strength in the radial direction is increased at the joint portion between the cylindrical porous bodies, and the force due to the pressurized gas from the hollow shaft is applied to the roll body constituted by the connected cylindrical porous bodies. Even if acts, it is avoided that the roll body is damaged at the connecting portion.
　本発明の他の好ましい態様によれば、
　一の筒状多孔質体の他の筒状多孔質体と接合されている軸線方向端面に少なくとも１つの環状凸部が形成され、
　前記他の筒状多孔質体の前記一の筒状多孔質体と接合されている端面に前記環状凸部と相補的な環状凹部が形成されている。 According to another preferred embodiment of the invention,
At least one annular convex portion is formed on the axial end surface joined to the other cylindrical porous body of one cylindrical porous body,
An annular concave portion complementary to the annular convex portion is formed on an end surface of the other cylindrical porous body joined to the one cylindrical porous body.
　このような構成によれば、筒状多孔質体同士の接続部分における径方向の強度がより増大し、接続された筒状多孔質体によって構成されるロール本体に、径方向内方から径方向外方に向かってより大きな力が作用しても、ロール本体が接続部分で破損することが回避される。 According to such a configuration, the strength in the radial direction at the connection portion between the cylindrical porous bodies is further increased, and the roll body constituted by the connected cylindrical porous bodies is changed from the radial inner side to the radial direction. Even if a larger force acts outward, it is possible to prevent the roll body from being damaged at the connecting portion.
　本発明の他の好ましい態様によれば、
　一の筒状多孔質体が他の筒状多孔質体と接合されている軸線方向端面に少なくとも１つの環状のバッファ溝が形成されている。 According to another preferred embodiment of the invention,
At least one annular buffer groove is formed on the axial end surface where one cylindrical porous body is joined to another cylindrical porous body.
　このような構成によれば、筒状多孔質体同士を接着剤で接合する際、余剰な接着剤が、隣接する筒状多孔質体と接合されている筒状多孔質体の軸線方向端面に形成された環状のバッファ溝に収容されるため、ウェブ支持面となる筒状多孔質体の表面側に流出し難くなり、ターンバーの品質が向上する。 According to such a configuration, when joining the cylindrical porous bodies with an adhesive, excess adhesive is applied to the end surface in the axial direction of the cylindrical porous body joined to the adjacent cylindrical porous body. Since it is accommodated in the formed annular buffer groove, it becomes difficult to flow out to the surface side of the cylindrical porous body serving as the web support surface, and the quality of the turn bar is improved.
　本発明の他の好ましい態様によれば、
　前記筒状多孔質体が、多孔質カーボンで構成されている。 According to another preferred embodiment of the invention,
The cylindrical porous body is made of porous carbon.
　本発明の他の好ましい態様によれば、
　前記筒状多孔質体の各々が長手方向中央位置で円周方向に延びる加圧空気流路を備え、
　前記中空シャフトが、径方向に延びて前記加圧空気流路に接続され、前記加圧空気流路に加圧エアを供給する径方向流路を有している。 According to another preferred embodiment of the invention,
Each of the cylindrical porous bodies comprises a pressurized air flow path extending in the circumferential direction at the longitudinal center position,
The hollow shaft has a radial flow path that extends in a radial direction and is connected to the pressurized air flow path and supplies pressurized air to the pressurized air flow path.
　本発明によれば、低い製造コストでありながらウェブを安定して支持できるターンバーが提供される。 According to the present invention, there is provided a turn bar that can stably support a web at a low manufacturing cost.
