Description

  The present invention relates to a plate mounting structure, and more particularly, to a plate mounting a thin plate-shaped plate on a cylindrical side surface provided on a drum.

  2. Description of the Related Art Conventionally, a plate including a cylindrical drum having a groove on a side surface and a plate holding member that is formed in a cylindrical shape having an outer diameter much smaller than that of the drum and is rotated (spinned) in the groove. Is known (see, for example, Patent Document 1).

The plate holding member holds the end portion of the plate and rotates by itself so that the plate can be wound on the side surface (outer periphery) of the plate while being in close contact with the plate. Then, the plate is pulled and the plate is brought into close contact with the outer peripheral surface of the drum so that it can be provided integrally with the drum.
JP-A 63-28648

  By the way, in the conventional plate mounting structure, when a metal plate is used instead of a plate made of a member such as rubber, the plate is wound up using the outer periphery of a small-diameter plate holding member. Plastic deformation is caused at a portion that is in close contact with the holding member.

  Further, since the plate is stretched at a relatively large crossing angle with respect to the tangential direction of the outer periphery of the arc-shaped drum, the plate not only undergoes plastic deformation at the portion in close contact with the holding member, but also the stiffness of the plate. May cause the plate to move away from the drum. As a result, uniform electrical continuity cannot be obtained in the electroplating apparatus, and uniform transfer is prevented in the transfer apparatus.

  Further, if the plate remains attached to the drum, no problem occurs even if the plate is plastically deformed, but the plate is used for maintenance of the plate (maintenance of the pattern provided on the plate). When it is removed from the drum and attached to the drum again, the position of the plate portion where the plastic deformation has occurred and the position of the outer periphery of the plate holding member are slightly shifted, and the plate is made of metal and is rigid. However, the plate is not easily deformed, and the plate may not be in close contact with the holding member or the drum, which makes it difficult to hold the plate accurately.

  The problem also occurs when the plate once removed from the drum is attached to a drum different from the drum (a drum having the same specifications as the drum). This is because even if the drum has the same specifications, the form is different although it is actually very small due to processing errors and the like.

  The above-mentioned problem also occurs in the same manner in a configuration in which the plate is bent and held at the boundary between the outer periphery of the drum and the groove (for example, see Japanese Patent Application Laid-Open No. 11-254463). It is.

  The plate 5 is formed in a thin plate shape such as a flat plate shape, and is made of a metal such as stainless steel, for example. A pattern formed with fine irregularities is provided on one surface in the thickness direction of the plate 5. The pattern is formed of, for example, a mesh-like (rectangular mesh shape such as a square) projection 7 as shown in FIG. 2 and a recess 9 that is recessed from the projection 7. In the convex portion 7, a stainless steel material is exposed, and in the concave portion 9, the stainless steel material is covered with an insulating layer.

  The plate 5 is attached integrally to the outer peripheral surface of the cylindrical side surface provided on the drum 3 using a plate attachment structure 1 (sometimes simply referred to as “attachment structure”). When the plate 5 is attached (installed), the other surface in the thickness direction of the plate 5 on which the fine pattern is not formed is in close contact with the outer peripheral surface of the drum 3.

  The drum 3 on which the plate 5 is installed is a film manufacturing in which a thin metal layer (for example, a thin layer of copper) similar to the convex portion 7 is provided on a thin sheet-like member (for example, a transparent resin film) 11. It is intended to be used in the device 13.

  More specifically, as shown in FIG. 3, the film manufacturing apparatus 13 includes a plating bath 15, and the lower side of the drum 3 on which the plate 5 is installed is immersed in the solution of the plating bath 15. At the same time, it is rotated by an actuator such as a motor (not shown). And while being immersed in the solution of the plating bath 15, a thin net-like copper film is formed on the convex portion 7 by plating.

  Rollers 17 and 19 are provided on the upper side of the drum 3, and the rollers 17 and 19 are rotated by an actuator (not shown) so that the sheet-like member 11 is sent from the roller 17 to the roller 19.

This film is transferred to the sheet-like member 11.

  The sheet-like member 11 to which the mesh-like thin copper film is transferred is cut into an appropriate form, for example, provided on the display surface of the plasma display, as a blocking film for blocking electromagnetic waves generated from the plasma display used.

  Here, the mounting structure 1 of the plate 5 will be described.

  FIG. 4 is an exploded perspective view showing a schematic configuration of the mounting structure 1. In FIG. 4, some components are not shown in order to prevent the drawing from becoming complicated.

  FIG. 5 is a view showing the V arrow in FIGS. 1 and 4. 6 is a sectional view taken along line VI-VI in FIG. 5, FIG. 7 is a sectional view taken along line VII-VII in FIG. 5, FIG. 8 is a sectional view taken along arrow VIII in FIG. It is IX-IX sectional drawing in. 4 and 5, only one end side of the attachment structure 1 is drawn in the extending direction of the central axis CL1 of the drum 3, but the other end side in the extending direction of the central axis CL1 is similarly configured. Is.

  At the outer periphery of the drum 3, a groove 23 extending in the extending direction of the central axis of the drum 3 (a central axis extending in a direction parallel to the outer peripheral surface of the cylindrical side surface of the drum 3; a rotating central axis of the drum 3) CL1. Is provided for a long time. The cross section of the groove 23 by a plane perpendicular to the central axis CL1 of the drum 3 is formed in a predetermined shape (for example, a substantially isosceles trapezoidal shape).

  The attachment structure 1 includes a holding member 25 and tension (pull) means 28. The holding member 25 can hold one end of the flat plate (sheet-like) plate 5 in the groove 23.

  The pulling means 28 pulls the holding member 25 holding one end of the plate 5, and the plate 5 comes into close contact with the outer periphery of the drum 3 by pulling with the pulling unit 28. In order to increase the electrical adhesion between the drum 3 and the plate 5, a felt-like carbon sheet 30 is provided on the entire surface between the drum 3 and the plate 5 (see FIGS. 6 and 7). .

  When viewed from the extending direction of the central axis CL1 of the drum 3, as shown in FIG. 6, the in-groove extending portion 29 of the plate 5 has an arc shape at the upper end 27 of the side surface 31 of the groove 23 by being pulled by the pulling means 28. The drum 3 extends linearly in the tangential direction of the outer periphery (see FIG. 6). The in-groove extending part 29 is a part of the plate 5 that is off the outer periphery of the drum 3 and extends at the groove 23, and excludes the part 33 that is held by the holding member 25. The in-groove extending portion 29 of the plate 5 may be linearly extended in a direction that intersects the tangential direction at a very small crossing angle and toward the bottom 35 side of the groove 23.

  When viewed from the extending direction of the central axis CL1 of the drum 3, the boundary 37 between the in-groove extending portion 29 and the portion 33 of the plate 5 held by the holding member 25 is the upper portion of the groove 23 (the bottom 35 of the groove 23). The tension means 28 is located along the arc whose center 37 is centered on the center axis CL1 of the drum 3 or on the outer circumference of the arc-shaped drum. The holding member 25 is configured to be pulled so as to move along a direction intersecting at a very small angle with respect to the tangential direction.

  The bottom (bottom) 35 of the groove 23 is located in the vicinity of the outer periphery of the drum 3, that is, the depth of the groove 23 is about 1/200 to 1/5 of the radius of the drum 3. When viewed from the extending direction of the central axis CL1 of the drum 3, the bottom surface 39 of the groove 23 is formed in an arc shape with the central axis CL1 of the drum 3 as the center. In consideration of the difficulty of forming the bottom surface 39 of the groove 23 in an arc shape, the arc-shaped bottom surface 39 includes a member 41 having an arc-shaped portion on the planar bottom portion 35 of the groove 23. It is formed by providing integrally. The holding member 25 contacts the arc-shaped bottom surface 39 of the groove 23 and moves along an arc centered on the central axis CL1 of the drum 3, and the boundary 37 becomes an arc (an arc in the vicinity of the outer peripheral surface of the drum 3). It is designed to move along.

  The mounting structure of the plate 5 will be described in more detail.

  As already understood, the drum 3 is formed in a columnar shape, and the groove 23 is provided on the outer periphery of the drum 3 along the extending direction of the central axis CL1 of the drum 3 over the entire length of the outer periphery. When viewed from the extending direction of the center axis CL1 of the drum 3, the bottom surface 39 of the groove 23 is formed in an arc shape (an arc shape whose radius is slightly smaller than the radius of the drum 3) with the center axis CL1 of the drum 3 as the center. ing.

  In the groove 23, two holding members 25 (25A, 25B) are installed.

  The holding member 25A has a length direction of the groove 23 (of the central axis CL1 of the drum 3) on one end side in the width direction of the groove 23 in the groove 23 (circumferential direction of the drum 3; left and right direction in FIGS. 6 and 7). It extends long in the extending direction (direction perpendicular to the paper surface of FIGS. 6 and 7). Further, when viewed from the extending direction of the central axis CL1 of the drum 3, the holding member 25A is configured to bend the one end portion 33 of the plate-like plate 5 that is bent toward the bottom 35 of the groove 23 with a predetermined width. The bent portion 37, which is a bent line portion, is held so as to be positioned on the upper side of the groove 23 on one end side in the width direction of the groove 23. The holding member 25A is in contact with the arc-shaped bottom surface 39 of the groove 23 on one end portion side in the width direction of the groove 23 in the groove 23, and is centered on the central axis substantially the same as the central axis CL1 of the drum 3. It moves in the circumferential direction of the drum 3.

  Further, a holding member 25B is provided symmetrically similarly to the holding member 25A on the other end side in the width direction of the groove 23 in the groove 23, and each holding member 25A, 25B, There is provided a biasing means 43 (pulling means 28) that biases (pulls) the holding members 25A and 25B so as to approach each other substantially in the width direction of the groove 23.

  By being configured in this manner, the plate 5 having an appropriate length is wound around the drum 3 with the back surface in the thickness direction (the surface on which the pattern is not formed) being in close contact with the outer peripheral surface of the drum 3. The drum 3 can be integrally installed. The length of the plate 5 is slightly shorter than the outer periphery of the drum 3, and the width of the plate 5 is slightly smaller than the width of the drum 3 (the length in the direction of the axis CL1). In addition, the structure by which one holding member (for example, holding member 25B) is being fixed to the drum 3 may be sufficient.

  Here, the holding member 25A and the like will be described in more detail with reference to FIGS.

  As shown in FIGS. 6 and 7, the holding member 25 </ b> A is formed in an “L” shape in cross section, and is in a direction perpendicular to the paper surface of FIGS. 6 and 7 (the extending direction of the axis CL <b> 1 of the drum 3). It extends. The length of the holding member 25 </ b> A is slightly shorter than the length of the groove 23. The holding member 25 </ b> A holds the one end portion 33 of the plate 5 on the upper side. More specifically, the one end 33 of the plate 5 is sandwiched and held in cooperation with the belt-like pressing member 44. The pressing member 44 is integrally attached to the holding member 25 </ b> A with a fastener such as a bolt 45.

  An obtuse triangular relief portion 48 is provided on the lower surface of the holding member 25 </ b> A, and the holding member 25 </ b> A is in contact with the arc-shaped bottom surface 39 of the groove 23 on both sides of the relief portion 48. Note that the lower surface of the holding member 25A may be formed in an arc shape (an arc shape having a radius equal to the bottom surface 39) without providing the escape portion 48.

  The angle α of the holding member 25A at the boundary (folding portion) 37 is an acute angle slightly smaller than 90 °, and prevents the plate 5 and the holding member 25A from interfering with each other at the in-groove extending portion 29. No extra external force is applied to 5. Further, a projection 47 formed in a columnar shape is integrally provided at a portion on the holding member 25B side of the holding member 25A using a fastener such as a bolt 49. Note that the holding member 25B is configured similarly to the holding member 25A.

  The urging means 43 urges the holding members 25A and 25B to approach each other using, for example, an O-ring 51.

  In other words, a plurality of O-rings 51 are provided at intervals in the longitudinal direction of each holding member 25A, 25B (the extending direction of the central axis CL1 of the drum 3). A plurality of engaging portions (for example, protrusions 47) for hanging the ring 51 are provided. The O-ring 51 is hung on each engaging portion 47 and extends in the width direction of the groove 23, and is urged so that the holding members 25A and 25B approach each other. An elastic body such as a tension spring may be used instead of the O-ring.

  In addition, “L” -shaped pressing members 53 are provided at both ends of the groove 23 in the longitudinal direction. These holding members 53 are fixed to the drum 3 with fasteners (not shown) such as bolts, and engage with both ends of the holding member 25 in the longitudinal direction (surfaces that slide on the arcuate surface 54). 8; see FIG. 8 and FIG. 9), and the holding member 25 is prevented from floating (jumping out of the groove 23).

  As shown in FIG. 10 (a diagram showing a modification of the installation form of the O-ring 51), the O-ring 51 portions extending between the engaging portions 47 may intersect at least once. . In other words, the O-ring 51 is considered as a belt of a belt transmission device, and each engagement portion 47 is provided integrally with each holding member 25A, 25B and does not rotate, but each engagement portion 47 is a belt of the belt transmission device. Considering a car, the O-ring 51 is provided like a crossed belt, for example. Note that the O-ring 51 may be provided in parallel as shown in FIG.

  The mounting structure 1 is provided with a cover 55 for preventing liquid (for example, plating solution) from entering the groove 23. The cover 55 includes a flat cover 57 that covers the upper portion of the groove 23, a flat cover 59 that covers both ends of the groove 23, and the like.

  The cover 57 is integrally provided on the drum 3 by a fastener such as a bolt 60, and the cover 59 is also integrally provided on the drum 3 by a fastener such as a bolt (not shown). It is like that. A plate-like sealing member 61 is installed between the cover 59 and the drum 3. Further, a seal tape 63 such as a Teflon (registered trademark) tape is provided on the gap between the cover 57 and the plate 5, the gap between the pressing member 53 and the cover 57, and the head of the bolt 60 of the cover 57. It is pasted.

  According to the mounting structure 1 of the plate 5, the in-groove extending portion 29 has a tangential direction of the outer periphery of the arc-shaped drum 3 at the upper end 27 of the side surface 31 of the groove 23 or a very small crossing angle with respect to the tangential direction. Since it is urged to extend linearly in the intersecting direction, plastic deformation does not occur in the groove extending portion 29 of the plate 5 and the portion engaged with the outer periphery of the drum 3 of the plate 5, Even when the plate 5 is once installed on the drum 3 and then removed from the drum 3, the plate 5 still maintains a form (for example, a flat plate shape; see FIG. 2) that is not attached to the drum 3. Therefore, when the plate 5 is installed on the drum 3, the plate 5 follows and closely contacts the outer periphery of the drum 3, and the plate 5 can be accurately held by the holding member 25, so that the plate 5 has good adhesion. In this state, the drum 3 can be accurately installed and held.

  As a result, uniform electrical conduction can be obtained in the electroplating of the film manufacturing apparatus 13, and uniform transfer can be performed.

  Further, according to the mounting structure 1 of the plate 5, the boundary 37 of the plate 5 is located at the upper portion of the groove 23, and the boundary 37 is moved along an arc centered on the central axis CL <b> 1 of the drum 3 by the pulling means 28. Therefore, the plate 5 can be pulled in an appropriate direction, and the plate 5 can be installed and held on the drum 3 more accurately.

  Further, according to the mounting structure 1 of the plate 5, the holding member 25 is moved in an arc shape in contact with the arc-shaped bottom surface 39 of the shallow groove 23, so that the mechanism has a simple configuration. Thus, a tensile force in an appropriate direction can be applied to the plate 5. That is, the end of the plate 5 is moved within the groove 23 along an arc that is concentric with the central axis CL1 of the drum 3 and approximately equal to the radius of the drum 3 in order to bring the plate 5 into close contact with the outer periphery of the drum 3 accurately. A swing member extending from the center axis CL1 of the drum 3 to the groove 23 (a swing member swinging about the center axis CL1 of the drum 3) is provided, and an end of the swing member on the groove 23 side (drum If the plate 5 is configured to be held at the end portion 3 located on the outer peripheral side of 3, the structure of the mechanism becomes complicated. In particular, when the outer diameter of the drum 3 becomes large (for example, when the outer diameter of the drum 3 becomes 2000 mm), the length of the rocking member becomes about 1000 mm, including support of the rocking member and the like. Although the structure of the mechanism is complicated, the mounting structure 1 does not use the swinging member as described above, so the structure of the mechanism is simplified.

  Further, in the mounting structure 1 of the plate 5, as shown in FIG. 10, when the holding members 25 are urged by crossing the O-rings 51, the urging direction of the holding members 25 and the extending direction of the O-ring 51 Substantially coincide with each other, and each holding member 25 can be urged efficiently.

  Further, as shown in FIG. 11 (a diagram showing a modified example of the holding method of one end of the plate 5), one end of the plate 5 is bent twice, and these bent portions are engaged with the holding member 25C. The plate 5 may be held by the holding member 25C. The plate 5 is bent at a substantially right angle at the first bent portion 37, and is bent at an obtuse angle of about 135 ° at the second bent portion 37A. A groove 25D is provided for accommodating a portion of the plate 5 on the end side with respect to the third bent portion 37A. With this configuration, the plate 5 can be held more accurately.

  Here, some modifications of the mode of engagement between each holding member 25 and the bottom surface of the groove 23 will be listed.

  First, as shown in FIG. 12 (a diagram showing a modification of the mode of engagement between each holding member 25 and the bottom surface 39 of the groove 23, a diagram corresponding to FIG. 6), An elongated rectangular relief portion 65 may be provided, and the holding member 25 may contact the arcuate bottom surface 39 of the groove 23 on both sides of the relief portion 65.

Is formed integrally with the drum 3, and the bottom surface 39 of the groove 23 is formed by a plurality of flat surfaces 39A and 39B which are similar to the arc-shaped bottom surface 39 shown in FIG. 6, and the flat surface of the holding member 25A is formed on the flat surface 39A. Alternatively, the bottom surface may be brought into surface contact with the flat surface 39B, and the bottom surface may be brought into surface contact with the flat surface 39B in the planar shape.

  Further, as shown in FIG. 15 (a diagram showing a modified example of the mode of engagement between each holding member 25 and the bottom surface 39 of the groove 23, a diagram corresponding to FIG. 6), in the mode shown in FIG. An obtuse triangular relief portion 48 may be provided on the lower surface of the member 25, and the holding member 25 may contact the flat surfaces 39 </ b> A and 39 </ b> B on both sides of the relief portion 48.

  Further, as shown in FIG. 16 (a diagram showing a modified example of the mode of engagement between each holding member 25 and the bottom surface 39 of the groove 23, a diagram corresponding to FIG. 6), in the mode shown in FIG. An elongated rectangular relief portion 65 may be provided on the lower surface of the member 25, and the holding member 25 may be in contact with the flat surfaces 39A and 39B on both sides of the relief portion 65.

  Further, as shown in FIG. 16 (a diagram showing a modified example of the mode of engagement between each holding member 25 and the bottom surface 39 of the groove 23, and corresponding to FIG. 6), in the mode shown in FIG. 23 may be constituted by three planes 39A, 39B, 39C.

  In order to reduce the coefficient of friction, the bottom surface 39 and the surface of the holding member 25 that is in contact with the bottom surface 39 may be subjected to a surface treatment such as plating.

  Next, some modifications of the urging means 43 are listed.

  In the embodiment shown in FIG. 18, each holding member 25 is biased by pulling the O-ring 51 using the turnbuckle 67.

  More specifically, the holding member 25A is provided with a plurality of engaging portions 47. The holding member 25B is also provided with a plurality of engaging portions 47. The respective engaging portions 47 of the holding member 25A and the respective engaging portions 47 of the holding member 25B are provided at positions that coincide with each other in the direction of the axis CL1 of the drum 3.
