According to the invention, a steering column is provided which guides a web-shaped workpiece (W) in a non-contact manner, wherein the steering column comprises: a cylindrical roller body (2) composed of a porous body; and an air ejection mechanism (4, 6b, 14) for ejecting air from the outer surface of the roller main body, wherein the roller main body is composed of a plurality of cylindrical porous bodies (12, 12; 8230; which are connected to each other at the end surfaces in the axial direction.
Description
Technical Field
The present invention relates to a steering rod (japanese: 12479125401251249612540and, in particular, to a steering rod for guiding a longitudinal film isopiem (japanese: 12454\\\ 1245512502).
Background
A processing method is known in which a web continuously fed from an upstream roller is processed while being conveyed along a predetermined path and wound around a downstream roller. In such a processing step, the web is subjected to processes such as printing, laminating, drying, cutting, and the like while being conveyed along a path defined by many rollers such as a feed roller (web feed 12426251251254012523), a guide roller, and a take-up roller.
These rollers are often made of metal or rubber, and the web is conveyed while being in contact with the surfaces of these rollers. Therefore, there is a problem in that the fine particles released from the rollers are transferred to the web, and the quality of the final product manufactured from the web is degraded.
Further, there are also problems as follows: the web is damaged, creased, stretched, and the like due to a speed difference between the web and the roller during conveyance, tension acting on the web, and a frictional force between the web and the roller, and the yield of the final product is reduced. Further, such a problem is remarkable in a steering lever portion that reverses the conveying direction of the web on the conveying path.
In order to cope with such a problem, a non-contact guide roller (steering lever) using an air film has been proposed (patent document 1). In the guide roller of patent document 1, pressurized gas is caused to flow into the hollow body having a large number of gas ejection holes formed in the surface thereof, whereby the gas is ejected from the gas ejection holes in the surface of the hollow body to support the longitudinal film along the outer peripheral surface of the hollow body in a non-contact manner, and the transport path of the longitudinal film is reversed.

Disclosure of Invention
Problems to be solved by the invention
The guide roller (steering rod) has an advantage that the longitudinal film can be inverted without contact, but when the discharge hole is formed by machining, the diameter of the discharge hole increases, and therefore the pressure difference between the right above the discharge hole and the periphery increases. As a result, there is a problem that the net film is liable to swing and cannot be stably supported. Further, when the discharge hole is formed by laser processing, there is a problem that the manufacturing cost becomes high.
The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a steering lever capable of stably supporting a net film at a low manufacturing cost.
Means for solving the problems
According to the present invention, there is provided a steering rod that guides a web-like workpiece in a non-contact manner, the steering rod comprising: a cylindrical roller body composed of a porous body; and an air ejection mechanism that ejects air from an outer surface of the roller main body, the roller main body being formed of a plurality of cylindrical porous bodies whose axial end surfaces are connected to each other.
According to this configuration, since the porous body having fine pores as a whole is used as the roller main body that supports the mesh membrane in a non-contact manner, the pressurized gas can be reliably ejected uniformly from the entire outer peripheral surface of the roller main body, and a step of forming the pores for ejecting the gas by machining is not necessary.
According to another preferred embodiment of the present invention, the air ejection mechanism includes a hollow shaft, the cylindrical roller body is attached to an outer peripheral surface of the hollow shaft, the cylindrical porous bodies are bonded to adjacent cylindrical porous bodies by adhesion, and a concave portion is provided on an inner peripheral surface in the vicinity of a bonding portion where the cylindrical porous bodies are bonded to the adjacent cylindrical porous bodies.
In the production process, when the remaining adhesive extruded from the joint portion flows out to the surface side of the cylindrical porous body serving as the web support surface when the cylindrical porous bodies constituting the roller main body are joined to each other with the adhesive, the blowing of the pressurized air from the web support surface is hindered, and the like, and the web support is affected.
However, according to the above-described configuration, when the cylindrical porous bodies are joined to each other with the adhesive, the adhesive is contained in the recessed portion provided on the inner peripheral surface in the vicinity of the joining portion with the adjacent cylindrical porous body, and therefore, the cylindrical porous bodies are more firmly joined to the hollow shaft by the adhesive in the recessed portion.
According to another preferred embodiment of the present invention, the recessed portion forms an annular groove extending in a circumferential direction on an inner circumferential surface of the cylindrical porous body.
According to another preferred embodiment of the present invention, the axial end face of one cylindrical porous body joined to the other cylindrical porous body and the end face of the other cylindrical porous body joined to the one cylindrical porous body have complementary convexo-concave shapes.
According to this configuration, the strength in the radial direction is increased at the joint portion between the cylindrical porous bodies, and even if the force of the pressurized gas from the hollow shaft acts on the roller main body composed of the cylindrical porous bodies connected to each other, the roller main body can be prevented from being damaged at the connection portion.
According to another preferred embodiment of the present invention, at least 1 annular convex portion is formed on an axial end surface of one cylindrical porous body to which the other cylindrical porous body is bonded, and an annular concave portion complementary to the annular convex portion is formed on an end surface of the other cylindrical porous body to which the one cylindrical porous body is bonded.
According to this configuration, the strength in the radial direction at the joint portion between the cylindrical porous bodies is further increased, and even if a larger force acts on the roller main body composed of the connected cylindrical porous bodies from the radially inner side toward the radially outer side, the roller main body can be prevented from being damaged at the joint portion.
According to another preferred embodiment of the present invention, at least 1 annular buffer groove is formed in an axial end surface of one cylindrical porous body joined to the other cylindrical porous body.
According to such a configuration, when the cylindrical porous bodies are joined to each other with the adhesive, the remaining adhesive is contained in the annular buffer groove formed in the axial end face of the cylindrical porous body joined to the adjacent cylindrical porous body, and therefore, it is difficult to flow out to the surface side of the cylindrical porous body which becomes the cap support surface, and the quality of the steering column is improved.
According to another preferred embodiment of the present invention, the cylindrical porous body is made of porous carbon.
According to another preferred embodiment of the present invention, each of the cylindrical porous bodies has a pressurized air flow path extending in a circumferential direction at a longitudinal center position, and the hollow shaft has a radial flow path extending in a radial direction and connected to the pressurized air flow path for supplying pressurized air to the pressurized air flow path.

Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Fig. 1 is a schematic perspective view of a steering rod 1 according to a preferred embodiment of the present invention, and fig. 2 is a sectional view taken along line II-II of fig. 1.
The turning lever 1 of the present embodiment is a member that is disposed on a conveying path for conveying a long web such as a long film, at a reversing portion for reversing the conveying direction of the web, and supports the web in a non-contact manner, and is used for changing the conveying direction of the web.
As shown in fig. 1 and 2, the steering rod 1 has a substantially cylindrical shape, and includes a substantially cylindrical roller body 2 made of porous carbon as a porous body and a substantially cylindrical hollow shaft 4 to which the roller body 2 is attached on an outer peripheral surface.
The hollow shaft 4 includes a hollow large diameter portion 6 at the center in the axial direction, and hollow small diameter portions 8 and 10 disposed at both ends of the large diameter portion 6. The large diameter portion 6 has an outer diameter substantially equal to the inner diameter of the roller body 2, and includes flanges 6a, 6a extending radially outward at both axial end portions, and the roller body 2 is mounted between the flanges 6a, 6 a. The internal space of the large diameter portion 6 is in fluid communication with the internal spaces of the small diameter portions 8 and 10, and pressurized air introduced through the small diameter portion flows into the internal space of the large diameter portion 6.
In the steering column 1 of the present embodiment, the roller body 2 is formed of 3 cylindrical porous bodies 12, 12. The cylindrical porous bodies 12, 12 have the same shape, and axial end faces of adjacent ones of the cylindrical porous bodies 12, 12 are bonded to each other by an adhesive, thereby forming the roller body 2. The roller body 2 is, specifically, formed by joining the cylindrical porous bodies 12, 12 to the hollow shaft with an adhesive.
Fig. 3 is an enlarged view of the vicinity of the cylindrical porous body 12 on one end side, and fig. 4 is a radial cross-sectional view of the cylindrical porous body 12 alone.
As shown in fig. 2 to 4, each of the cylindrical porous bodies 12 includes an annular pressurized air flow path 14 extending in the circumferential direction at the longitudinal center position of the inner circumferential surface.
On the other hand, as shown in fig. 2 and 3, an air supply passage 6b penetrating the peripheral wall of the large diameter portion 6 in the radial direction is formed in a portion of the large diameter portion 6 of the hollow shaft 4 located radially inside each pressurized air flow passage 14 of the cylindrical porous body 12. As a result, the internal spaces of the large-diameter portion 6, the small-diameter portion 8, and the small-diameter portion 10 of the hollow shaft 4 are in fluid communication with the respective pressurized air flow passages 14 of the cylindrical porous body 12 via the air supply passage 6b, and a radial flow passage for supplying pressurized air to the pressurized air flow passages is formed.
Each of the cylindrical porous bodies 12 has annular recesses 16 having notch portions at both axial end portions of the inner peripheral surface. In the roller body 2 in which the cylindrical porous bodies 12, 12 adjacent to each other in the axial direction are joined to each other, the opposing concave portions 16, 16 of the cylindrical porous bodies 12, 12 adjacent to each other are communicated with each other, and an annular groove 17 extending in the circumferential direction near the joint portion is formed in the inner circumferential surface of the roller body 2.
The end of the joint between the adjacent cylindrical porous bodies 12, 12 is located in the annular groove 17. The annular groove 17 accommodates a part of the adhesive for bonding the cylindrical porous bodies 12, 12 to each other, and the adhesive in the annular groove 17 further firmly bonds the roller body 2, more specifically, the respective cylindrical porous bodies 12, 12 to the hollow shaft 4.
The depth (radial length) of the annular groove 17 is preferably set to 1:60 (2%) 1:13 (8%), it is more preferable to set the length (length in the axial direction) of the annular groove 17 to 4% to 5%.
In the steering column 1 of the present embodiment, the axial one end surface 18 and the axial other end surface 20 of each cylindrical porous body 12 have the same complementary shape. Specifically, as shown in fig. 4, one end surface 18 in the axial direction of each cylindrical porous body 12 has an annular convex step portion 22 protruding stepwise outward in the axial direction on the inner side in the circumferential direction, and the other end surface 20 in the axial direction of each cylindrical porous body 12 has an annular concave step portion 24, and the concave step portion 24 is recessed stepwise inward in the axial direction complementary to the annular convex step portion 22 protruding outward in the axial direction.
Therefore, when the one cylindrical porous body 12 and the other cylindrical porous body 12 are connected with the one end surface 18 of the one cylindrical porous body 12 and the other end surface 20 of the other cylindrical porous body 12 being joined together as shown in fig. 3, the annular step portion 22 of the one axial end surface 18 of the one cylindrical porous body 12 is fitted to the annular step portion 24 of the other axial end surface 20 of the other cylindrical porous body 12 as shown in fig. 2 and 3, and high mechanical strength against a force in the radial direction can be obtained.
In the steering column 1 of the present embodiment, an annular buffer groove 26 is formed at a position radially outside the other end surface 20 in the axial direction of the cylindrical porous body 12. The remaining portion of the adhesive for bonding the cylindrical porous bodies 12, 12 to each other is also accommodated in the annular buffer groove 26.
In the steering column 1 thus configured, when pressurized air is introduced into the internal space of the large diameter portion 6 through the small diameter portions 8 and 10 of the hollow shaft 4 as shown by arrows a and B in fig. 2, the pressurized air flows into the respective pressurized air flow passages 14 of the cylindrical porous body 12 through the air supply passage 6B as shown by arrow C in fig. 3, passes through the interior of the cylindrical porous body 12 formed of porous carbon having air permeability, and is ejected from the entire outer surface of the roller body 2 formed of the cylindrical porous body 12 as shown by arrow D in fig. 3.
As a result, as shown in fig. 5, the web W is supported on the outer peripheral surface of the roller main body 2 in a non-contact manner, and the conveying path can be reversed.
Next, a method of manufacturing the steering column 1 of the present embodiment will be described.
Fig. 6 to 8 are views schematically showing a process of attaching the cylindrical porous body 12 to the hollow shaft 4 in the process of manufacturing the steering column 1.
First, as shown in fig. 6, the 1 st cylindrical porous body 12 is attached to a predetermined position on the outer peripheral surface of the hollow shaft 4, and the adhesive S is disposed on the other end surface of the 1 st cylindrical porous body 12 in the axial direction. Next, as shown in fig. 7, the 2 nd cylindrical porous body 12' is arranged at a predetermined position on the outer peripheral surface of the hollow shaft 4 while being pressed against the other end surface of the 1 st cylindrical porous body 12 on which the adhesive S is arranged, on the outer peripheral surface of the hollow shaft 4.
Next, as shown in fig. 8, the adhesive S is disposed on the other end surface of the 2 nd cylindrical porous body 12' in the axial direction. Finally, the 3 rd cylindrical porous body is arranged at a predetermined position on the outer peripheral surface of the hollow shaft 4 while being pressed against the other end surface of the 2 nd cylindrical porous body 12' on which the adhesive S is arranged. The adhesive for bonding the cylindrical porous bodies to each other also bonds the cylindrical porous bodies to the hollow shaft.
When the 2 nd cylindrical porous body or the 3 rd cylindrical porous body is pressed against the other end face of the 1 st cylindrical porous body or the 2 nd cylindrical porous body on which the adhesive S is arranged on the outer peripheral surface of the hollow shaft 4, the adhesive S is pressed and spread. At this time, the remaining adhesive S is contained in the annular concave portion 16 formed in the vicinity of the joint portion of the adjacent cylindrical porous bodies and the buffer groove 26 of the other end surface 20 of the cylindrical porous body 12, and the adhesive S can be prevented from overflowing to the outer circumferential surface side of the roller main body 2.
At this time, a part of the adhesive S is accommodated in an annular recess 16 formed near the joining portion of the adjacent cylindrical porous bodies, and the porous body 12 and the hollow shaft 4 are joined. The remaining adhesive S is contained in the buffer groove 26 of the other end surface 20 of the cylindrical porous body 12, and the adhesive S can be prevented from overflowing toward the outer peripheral surface side of the roller main body 2.
The present invention is not limited to the above-described embodiments, and various modifications and variations can be made within the scope of the technical idea described in the claims.
In the steering column 1 of the above embodiment, the cylindrical porous body is formed of porous carbon, but may be formed of other porous materials such as porous ceramics and porous metals.
Further, the steering column 1 of the above embodiment is configured such that the annular buffer groove is formed at a position radially outside the other end surface in the axial direction of the cylindrical porous body, but a configuration in which the buffer groove is not provided or a configuration in which other forms (arrangement, number) of buffer grooves are provided may be adopted.
In the above embodiment, the one axial end face 18 of each cylindrical porous body 12 has the annular convex step portion 22 projecting stepwise outward in the axial direction on the inner side in the circumferential direction, and the other axial end face 20 of each cylindrical porous body 12 has the annular concave step portion 24, and the concave step portion 24 is recessed stepwise inward in the axial direction in a manner complementary to the annular convex step portion 22 projecting outward in the axial direction, but may have a configuration complementary only to the end face which is a joint portion between the cylindrical porous bodies.
The shape and position of the step portion may be other. For example, as shown in fig. 9, a configuration may be adopted in which a complementary shape is realized by a convex step portion 220 formed by an inclined surface and a concave step portion 240 complementary to the convex step portion 220. As shown in fig. 10, the convex portion 320 and the complementary concave portion 340 provided at the radial center may be configured to have complementary shapes.
