Description

Technical Field

[0001] The present invention relates to a foil conveying device and a foil corrugation applying device. Background Art

[0002] An exhaust gas purification catalyst (filter) is used to purify harmful substances contained in exhaust gas discharged from an internal combustion engine. The exhaust gas purification catalyst has a honeycomb body serving as a base for a metal carrier on which a catalyst is arranged, held in an outer cylinder.

[0003] Honeycomb bodies, which serve as the base of the metal substrate, are generally manufactured by winding a structure in which foil-like flat plates and corrugated plates are alternately stacked. For example, as disclosed in Japanese Patent Application Laid-Open No. 7-108176 and Japanese Patent Application Laid-Open No. 2005-066665, when manufacturing corrugated plates stacked on flat plates, a foil (a foil-like flat plate) drawn from a supply source such as a coil (unprocessed coil) is conveyed by a conveyor device and corrugated by a corrugating unit.

[0004] In this case, if the foil used to form the corrugated sheet is conveyed in a meandering manner to the corrugation applying unit, the quality of the corrugated sheet corrugated by the corrugation applying unit may fluctuate. Therefore, it is required to convey the foil while suppressing meandering in a predetermined direction when the foil is drawn from the supply source. Summary of the Invention

[0005] An object of the present invention is to provide a foil conveying device capable of conveying a drawn-out foil while suppressing meandering when conveying the foil in a predetermined conveying direction, and a foil corrugation device including the conveying device.

[0006] One embodiment of the present invention relates to a foil conveying device that conveys a foil having a pair of side ends extending parallel to each other and at least a portion having a non-perforated portion extending continuously along a conveying direction toward a corrugation applying section that performs a corrugation application process. The conveying device includes: a delivery section that delivers the foil in a direction parallel to the pair of side ends; a first foil pressing member that is disposed on a path between the delivery section and the corrugation applying section and delivers the foil between the delivery section and the corrugation applying section toward the corrugation applying section; and a second foil pressing member that is disposed on a path between the first foil pressing member and the corrugation applying section and is separated from the first foil pressing member along the conveying direction of the foil and delivers the foil between the corrugation applying section and the first foil pressing member toward the corrugation applying section. The first foil pressing member and the second foil pressing member each have a pressing portion that presses the non-perforated portion while applying a predetermined tension to the foil in the conveying direction as the foil moves in the conveying direction. The pressing portion of the first foil pressing member and the pressing portion of the second foil pressing member are separated in a direction parallel to the conveying direction.

[0007] According to the present invention, it is possible to provide a foil conveying device capable of conveying a drawn-out foil while suppressing meandering when conveying the foil in a predetermined conveying direction, and a foil corrugation device including the conveying device.

[0013] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0014] (First embodiment)

[0015] Figure 1 1 is a schematic diagram of a corrugation device 10 as a part of a manufacturing device 200 for a honeycomb body 300 serving as a base of a metal substrate. Figure 2 Shown in the figure as viewed from above Figure 1 A schematic diagram of a corrugation applying device 10 of a manufacturing device 200. Figure 3 The use of Figure 1 and Figure 2 Schematic diagram of a conveying device 400 and a winding device 500 in which a corrugated sheet 100 a corrugated by the corrugation applying device 10 of the manufacturing device 200 forms a part of the manufacturing device 200 of the honeycomb body 300.

[0016] also, Figures 1 to 3 The XYZ orthogonal coordinate system is defined in [1]. The X-axis is along the conveying direction of the thin-plate foil 100 (corrugated plate 100a) and flat plate 150. The Y-axis is along the width direction of the foil 100 (corrugated plate 100a) and flat plate 150. The width direction is perpendicular to the conveying direction. The Z-axis is perpendicular to the conveying direction and the width direction of the foil 100 (corrugated plate 100a) and flat plate 150. Preferably, the Z-axis is oriented in the vertical direction.

[0017] First, a series of methods (manufacturing steps) for manufacturing the honeycomb body 300 serving as a base of the metal support will be briefly described.

[0018] like Figure 1 and Figure 2 As shown in FIG. 1 , the foil 100 is processed to form a corrugated plate 100a. Then, after the corrugated plate 100a is cut into a predetermined length, Figure 3 As shown, a flat plate 150 of a predetermined length is placed, for example, below the corrugated plate 100a, and the stack of the corrugated plate 100a and the flat plate 150 is conveyed to the winding device 500 by the clamps 410a and 410b of the conveying device 400. At this time, the length of the corrugated plate 100a (not the length of the foil 100) and the length of the flat plate 150 may be the same or different. When the honeycomb body 300 is formed by winding in a roll as described later, the longitudinal ends of the corrugated plate 100a do not extend excessively or are not pulled in excessively relative to the longitudinal ends of the flat plate 150.

[0019] The winding device 500 then rolls the stack of the corrugated sheet 100a and the flat sheet 150 into a roll around a predetermined rotation axis 500a while moving the flat sheet 150 on the rollers 510a and 510b of the winding device 500, thereby forming the honeycomb body 300. Furthermore, depending on the arrangement of the foil 100 conveyor 12 and the winding device 500, the rotation axis 500a is parallel to the rotation axis 22a1 described later. Furthermore, the rollers 510a and 510b of the winding device 500 are parallel to the rotation axis 500a. Furthermore, the rollers 510a and 510b of the winding device 500 can be parallel to the rotation axis 22a1.

[0020] The foil 100 (corrugated plate 100a) and the flat plate 150 are formed of a metal material such as stainless steel.

[0021] In this embodiment, mainly Figure 1 and Figure 2 1 and 2, which illustrate a corrugation device 10 for processing a foil 100 to produce a corrugated sheet 100a. The corrugated sheet produced and cut by the corrugation device 10 is required to have the corrugations of the corrugated sheet 100a formed to a predetermined quality when it is stacked with a flat plate 150 and formed into a honeycomb body 300 by a winding device 500.

[0022] The corrugating device 10 includes a conveying device 12 for the foil 100 and a corrugating unit 14 that performs corrugation processing on the foil 100 .

[0023] like Figure 2 As shown, in the present embodiment, the foil 100 has a non-perforated portion (non-perforated belt) 110 extending continuously in one direction of conveying direction (X-axis direction) in at least a portion, and a pair of side ends (two ends) 112, 114 extend parallel to each other. The area of the foil 100 including the pair of side ends 112, 114 is formed as the non-perforated portion 110. In addition, based on the side end area including the pair of side ends 112, 114 of the foil 100 involved in the present embodiment, a total of three areas, such as the area of the central portion in the width direction between the pair of side ends 112, 114, at a position separated from the pair of side ends 112, 114, are formed as the non-perforated portion 110. That is, in the present embodiment, the foil 100 has three non-perforated portions 110 that are longer in the longitudinal direction and arranged in the width direction.

[0024] The longitudinal direction of the foil 100 is defined as a direction along the extending direction of the pair of side ends 112, 114 of the foil 100. The width direction of the foil 100 is defined as a direction (short side direction) perpendicular to the extending direction (longitudinal direction) of the pair of side ends 112, 114.

[0025] Perforated sections (perforated strips) 120 are formed between adjacent non-perforated sections 110, each of which is formed by regularly arranged, for example, circular perforations 122. The perforations 122 of the perforated section 120 are arranged at predetermined intervals along the extension direction (conveying direction) of the foil 100. The perforations 122 of the perforated section 120 are arranged in a staggered pattern at predetermined intervals along the width direction perpendicular to the extension direction of the foil 100. The perforations 122 can be formed in any appropriate shape, such as a polygon or an ellipse.

[0026] In addition, although the example which has the perforated part 120 in the foil 100 is demonstrated here, the perforated part 120 (perforation 122) is not indispensable. That is, the whole foil 100 may be formed as the non-perforated part 110.

[0027] The foil 100 of the coil 22a preferably has the perforations 120 formed in advance. The perforations 120 may be formed by punching or the like immediately before the foil 100 is conveyed from the coil 22a to the conveyor 12 , ie, between the coil 22a and the conveyor 12 .

[0028] The conveying device 12 includes a supply unit 22 , a first foil presser (door) 24 including a presser 240 and a support 241 , a second foil presser (door) 26 including a presser 260 and a support 261 , and a pair of guide members 28 a and 28 b .

[0029] An example of the supply unit 22 is a coil (unprocessed coil) 22a that winds the foil 100 into a roll. The foil 100 is pulled out from the coil 22a wound on a cylindrical core (not shown). The rotation axis 22a1 of the coil 22a is parallel to the Y axis and horizontal to the floor surface. The foil 100 is formed in a thin plate shape with a constant thickness along the Z axis and is longer in the longitudinal direction (extension direction) along the X axis relative to the width along the Y axis. The length of the foil 100 in the longitudinal direction is at least greater than or equal to 10m, for example, appropriately set to about 50m.

[0030] The supply unit 22 rotates the coil 22a around the rotation axis 22a1. Therefore, the supply unit 22 can deliver the thin-plate-shaped foil 100 in a predetermined conveying direction. This conveying direction is parallel to the longitudinal direction (conveying direction) of the foil 100.

[0031] The first foil pressing member 24 is disposed on the path between the material coil 22a and the corrugation applying unit 14, and is arranged opposite the material coil 22a. The first foil pressing member 24 feeds the foil 100 between the material coil 22a and the corrugation applying unit 14 toward the corrugation applying unit 14. At this time, the first foil pressing member 24 presses the foil 100 in a manner that prevents the foil 100 from meandering, in coordination with the supply of the foil 100 by the supply unit 22, the pressing of the foil 100 by the second foil pressing member 26, and the corrugation of the foil sheet 100 by the corrugation applying unit 14.

[0032] The second foil pressing member 26 is provided on the path between the first foil pressing member 24 and the corrugation applying unit 14. The second foil pressing member 26 is separated from the first foil pressing member 24 along the conveying direction of the foil 100. The second foil pressing member 26 delivers the foil 100 between the corrugation applying unit 14 and the first foil pressing member 24 toward the corrugation applying unit 14. At this time, the second foil pressing member 26 presses the foil 100 in a manner that cooperates with the supply of the foil 100 by the supply unit 22, the pressing of the foil 100 by the first foil pressing member 24, and the corrugation application by the corrugation applying unit 14 to suppress the meandering movement of the foil 100.

[0033] In this embodiment, the pressing portion 240 of the first foil pressing member 24 continuously presses the non-perforated portion 110 in the widthwise central portion of the foil 100, which is moving in the conveying direction, relative to the support portion 241 when the foil 100 is conveyed. Preferably, the pressing direction of the pressing portion 240 is directed vertically downward (in the -Z-axis direction). On the other hand, the first foil pressing member 24 of this embodiment does not press the area of the foil 100 that includes the pair of side ends 112 and 114.

[0034] Furthermore, the pressing portion 260 of the second foil pressing member 26 continuously presses the non-perforated portion 110 in the widthwise central portion of the foil 100, which is moving in the conveying direction, relative to the support portion 261 when the foil 100 is conveyed. Preferably, the pressing direction of the pressing portion 260 is directed vertically downward (in the -Z-axis direction). On the other hand, the second foil pressing member 26 of this embodiment does not press the area of the foil 100 that includes the pair of side ends 112 and 114.

[0035] Therefore, the set of the pressing portion 240 and the supporting portion 241 of the first foil pressing member 24 and the set of the pressing portion 260 and the supporting portion 261 of the second foil pressing member 26 respectively continuously support the non-perforated portion 110 in the widthwise central portion of the foil 100, which continuously extends along the longitudinal direction along the conveyance direction (X-axis direction) of the foil 100. In other words, the non-perforated portion 110 in the widthwise central portion of the foil 100 is conveyed in a predetermined direction (conveying direction) while being supported by the pressing portion 240 of the first foil pressing member 24 and by the pressing portion 260 of the second foil pressing member 26.

[0036] The first foil pressing member 24 has a cylinder (first cylinder) 244 that extends and retracts in a manner that presses the pressing portion 240 toward the foil 100 and the support portion 241. The cylinder 244 is provided, for example, directly above the pressing portion 240, so that the pressing portion 240 moves in the up and down directions. The cylinder 244 presses the pressing portion 240 in the central portion in the width direction of the pressing portion 240 toward the non-perforated portion 110 in the central portion in the width direction of the foil 100, for example, with a constant pressure, and presses the non-perforated portion 110. That is, the first cylinder 244 presses the non-perforated portion 110 of the foil 100 via the pressing portion 240 of the first foil pressing member 24, for example, with a constant pressure. The first foil pressing member 24 exerts appropriate sliding resistance on the foil 100 by utilizing the pressing portion 240 and the support portion 241 opposite to the pressing portion 240.

[0037] The second foil pressing member 26 has a cylinder (second cylinder) 264 that extends and retracts in a manner that presses the pressing portion 260 toward the foil 100 and the support portion 261. The cylinder 264 is provided, for example, directly above the pressing portion 260, so that the pressing portion 260 moves in the up and down directions. The cylinder 264 presses the pressing portion 260 in the central portion in the width direction of the pressing portion 260 toward the non-perforated portion 110 in the central portion in the width direction of the foil 100, for example, with a constant pressure, and presses the non-perforated portion 110. That is, the second cylinder 264 presses the non-perforated portion 110 of the foil 100 via the pressing portion 260 of the second foil pressing member 26, for example, with a constant pressure. The second foil pressing member 26 exerts appropriate sliding resistance on the foil 100 by utilizing the pressing portion 260 and the support portion 261 opposite to the pressing portion 260.

[0038] For example, it is preferable that the sliding resistance of the pressing portion 240 and the supporting portion 241 of the first foil pressing member 24 on the upstream side against the non-perforated portion 110 of the foil 100 is greater than the sliding resistance of the pressing portion 260 and the supporting portion 261 of the second foil pressing member 26 on the downstream side against the non-perforated portion 110 of the foil 100. In this case, the pressing portion 260 and the supporting portion 261 of the second foil pressing member 26 on the downstream side can more easily slide the non-perforated portion 110 in the widthwise central portion of the foil 100, thereby conveying the foil 100 downstream, compared to the pressing portion 240 and the supporting portion 241 of the first foil pressing member 24 on the upstream side. Therefore, appropriate tension can be applied to the foil 100 in the conveyance direction between the first foil presser 24 and the second foil presser 26 , thereby preventing the foil 100 from being retained between the first foil presser 24 and the second foil presser 26 and being bent in the conveyance direction.

[0039] The appropriate tension here refers to the tension in the conveying direction between the first foil pressing member 24 and the second foil pressing member 26, which is used to convey the foil 100 to the corrugation applying unit 14 in a state where corrugations are applied between the rollers 14a and 14b of the corrugation applying unit 14 without cutting the foil 100 or bending the foil 100.

[0040] Moreover, by adjusting the conveyance speed of the foil 100 by the supply unit 22 using a control device (not shown), the accumulation of the foil 100 on the upstream side of the first foil presser 24 is suppressed.

[0041] The areas of the pressing portion 240 and support portion 241 set, and the pressing portion 260 and support portion 261 set, that come into contact with the non-perforated portion 110 of the foil 100 are formed without corners to prevent scratching of the non-perforated portion 110 of the foil 100. Furthermore, the areas of the pressing portion 240 and support portion 241 set, and the pressing portion 260 and support portion 261 set that come into contact with the non-perforated portion 110 of the foil 100 are not made of a material or shape that excessively brakes the foil 100 so as to prevent it from bending during transport and maintain its flat state. Instead, they are made of a material or shape that maintains appropriate sliding properties.

[0042] Furthermore, the pressing portions 240 and 260 are formed to have a size that does not come into contact with the perforated portions 120 between the non-perforated portions 110 of the foil 100 .

[0043] Moreover, in the present embodiment, the pressing portion 240 of the first foil pressing member 24 and the pressing portion 260 of the second foil pressing member 26 are respectively formed into a linear shape extending in a predetermined direction (conveying direction). For example, the cross-section in the YZ plane of the lower end of the pressing portion 240, 260 is formed into a downwardly convex curved surface such as a hemispherical shape. In addition, if the pressing portion 240 abuts against the foil 100, for example, a contact surface having an appropriate width in the width direction and a length in the length direction of the pressing portion 240 is formed due to elastic deformation. At this time, the pressing portion 240 is pressed in the region of the non-perforated portion 110 facing the foil 100 with the same width as the non-perforated portion 110 or a width smaller than the non-perforated portion 110. Here, the length direction of the pressing portion 240 is set to be along the X-axis direction, ignoring the size of the width in the width direction. In this case, the pressing portion 240 can press the non-perforated portion 110 of the foil 100 in a straight line. Similarly, if the pressing portion 260 contacts the foil 100, for example, a contact surface having an appropriate width in the width direction and, in the length direction, for example, the length direction of the pressing portion 260 is formed due to elastic deformation. At this time, the pressing portion 260 presses in the area of the non-perforated portion 110 facing the foil 100 with the same width as the non-perforated portion 110 or a width smaller than the non-perforated portion 110. Here, the length direction of the pressing portion 260 is set to be along the X-axis direction, and the size of the width in the width direction is ignored. In this case, the pressing portion 260 can press the non-perforated portion 110 of the foil 100 that is the same as the pressing portion 240 in a straight line. The virtual line segment connecting the linear pressing areas of the pressing portions 240 and 260 is parallel to the conveying direction of the foil 100. That is, the separation direction (the direction along which the imaginary line segment follows) of the pressing portion 240 of the first foil pressing member 24 and the pressing portion 260 of the second foil pressing member 26 is parallel to the conveyance direction of the foil 100 from the supply unit 22. Therefore, the conveying device 12 presses the common non-perforated portion 110 of the foil 100 in a linear manner at two separate locations (the combination of the pressing portion 240 and the support portion 241, and the combination of the pressing portion 260 and the support portion 261) while conveying the foil 100 in a predetermined direction. Consequently, vibration of the foil 100 is suppressed, and the non-perforated portion 110 of the foil 100 is less likely to deviate from the conveyance direction due to the aforementioned tension applied in the conveyance direction. Consequently, the foil 100 is conveyed in the conveyance direction with its meandering motion suppressed.

[0044] In addition, the first pressing line area 242 is included in the area where the pressing portion 240 in the width direction center of the first foil pressing piece 24 presses the non-perforated portion 110. In the present embodiment, the support portion 241 opposite to the pressing portion 240 is formed into a cylindrical shape that protrudes upward. Therefore, the contact area between the pressing portion 240 and the non-perforated portion 110 of the foil 100 does not need to be formed long in the length direction. The second pressing line area 262 is included in the area where the pressing portion 260 in the width direction center of the second foil pressing piece 26 presses the non-perforated portion 110. In the present embodiment, the support portion 241 opposite to the pressing portion 260 is formed into a cylindrical shape that protrudes upward. Therefore, the contact area between the pressing portion 260 and the non-perforated portion 110 of the foil 100 does not need to be formed long in the length direction. At this time, the line segment connecting the linear first pressing line area 242 and the linear second pressing line area 262 is virtually parallel to the specified direction (conveying direction), that is, the X-axis direction. Therefore, by using the two separate locations (two points) of the group of the pressing part 240 and the supporting part 241 and the group of the pressing part 260 and the supporting part 261 to support the non-perforated portion 110 extending in the longitudinal direction, it is possible to apply appropriate tension to the foil 100 while conveying it to the downstream side. Therefore, similar to the case where the group of the pressing part 240 and the supporting part 241 and the group of the pressing part 260 and the supporting part 261 are in contact in a straight line, the non-perforated portion 110 of the foil 100 is not easily deviated from the conveying direction due to the above-mentioned tension applied in the conveying direction, and is conveyed in the conveying direction while the meandering movement of the foil 100 is suppressed.

[0045] The pair of guide members 28a and 28b are, for example, provided between the first foil pressing member 24 and the second foil pressing member 26. Although not shown in the figures, it is also preferable to provide guide members identical to the pair of guide members 28a and 28b for the first foil pressing member 24, and to provide guide members identical to the pair of guide members 28a and 28b for the second foil pressing member 26. Furthermore, it is also preferable to provide, for example, a guide member 28c identical to the pair of guide members 28a and 28b between the second foil pressing member 26 and the corrugation applying unit 14.

[0046] The pair of guide members 28a and 28b are formed with elongated holes 28a1, 28a2, 28b1, and 28b2, for example, extending along the width direction (Y-axis direction). A plate (not shown) is disposed below each of the pair of guide members 28a and 28b. Furthermore, screws 29a1, 29a2, 29b1, and 29b2 are secured to the plate through the elongated holes 28a1, 28a2, 28b1, and 28b2, thereby enabling positional adjustment of the pair of guide members 28a and 28b.

[0047] The pair of guide members 28a and 28b guide the pair of side ends 112 and 114 of the foil 100, respectively. The pair of guide members 28a and 28b are formed, for example, as parallel planes. Therefore, the pair of guide members 28a and 28b prevent the pair of side ends 112 and 114 from deviating from the conveyance direction and prevent the foil 100 from meandering.

[0048] Furthermore, if the meandering of the foil 100 can be suppressed by the first foil presser 24 and the second foil presser 26 , the pair of guide members 28 a and 28 b may be unnecessary.

[0049] The corrugation applying unit 14 includes, for example, a pair of corrugating rollers 14a and 14b, which apply corrugation to the foil 100. The rotation axes 14a1 and 14b1 of the pair of corrugating rollers 14a and 14b are parallel to the rotation axis 22a1 of the web 22a. Preferably, the rotation axes 14a1 and 14b1 are separated in the Z-axis direction. The outer circumferences of the corrugating rollers 14a and 14b are each formed with a plurality of teeth, similar to spur gears. The teeth of the corrugating rollers 14a and 14b are formed parallel to the width direction (Y-axis direction) of the foil 100.

[0050] The teeth on the outer circumferential surfaces of the corrugation rollers 14a and 14b mesh with each other, applying corrugations to the foil 100 as it passes between the corrugation rollers 14a and 14b. Thus, the foil 100 passing between the corrugation rollers 14a and 14b from upstream to downstream is formed into a corrugated sheet 100a. Immediately after the corrugations are applied, the corrugated sheet 100a is cut, for example, to a predetermined length. Alternatively, the sheet 100a may be temporarily wound, for example, as the coil 22a, and then cut when the honeycomb body 300 is formed.

[0051] According to this embodiment, the group of the pressing portion 240 and the supporting portion 241 of the first foil pressing member 24 and the group of the pressing portion 260 and the supporting portion 261 of the second foil pressing member 26 are separated in the conveying direction. Moreover, the non-perforated portion 110 of the foil 100 can be supported at two locations using the group of the pressing portion 240 and the supporting portion 241 of the first foil pressing member 24 and the group of the pressing portion 260 and the supporting portion 261 of the second foil pressing member 26. At this time, the foil 100 can be loaded with appropriate tension between the group of the pressing portion 240 and the supporting portion 241 of the first foil pressing member 24 and the group of the pressing portion 260 and the supporting portion 261 of the second foil pressing member 26, and thus conveyed to the corrugation applying unit 14. Therefore, due to the tension of the load in the conveying direction, the non-perforated portion 110 of the foil 100 is not easy to deviate from the conveying direction. While suppressing the meandering movement of the foil 100, the foil 100 is conveyed along the specified conveying direction (the corrugation applying portion 14 on the downstream side) using the conveying device 12.

[0052] Therefore, according to this embodiment, it is possible to provide a conveying device 12 for conveying the foil 100 to the corrugation applying unit 14 while suppressing meandering when conveying the foil 100 led out in a predetermined direction, and a corrugation applying device 10 for the foil 100 including the conveying device 12 .

[0053] Furthermore, by utilizing the guide members 28 a and 28 b , the led-out foil 100 can be conveyed to the corrugation applying unit 14 in a predetermined direction while further suppressing meandering.

[0054] In this embodiment, an example is described in which the first foil pressing member 24 of the conveyor device 12 includes the air cylinder 244, and the second foil pressing member 26 includes the air cylinder 264. If the non-perforated portion 110 of the foil 100 can be pressed with an appropriate pressure without using the air cylinders 244 and 264, for example, if a sliding resistance within a predetermined range can be achieved between the pressing members 240 and 260 and the foil 100, the air cylinders 244 and 264 may not be necessary.

[0055] Alternatively, instead of the air cylinders 244 and 264 described in this embodiment, pressure sensors or the like may be disposed on the support portions 241 and 261, and the pressing portions 240 and 260 may be moved by a servo motor or the like through feedback control. In this case, the pressing portions 240 and 260 can be controlled so that a desired pressing force is applied to the non-perforated portion 110 of the foil 100. Furthermore, an appropriate actuator may be used as a structure for moving the pressing portions 240 and 260 toward and away from the support portions 241 and 261.

[0056] In this embodiment, the foil 100 is described as having the perforated portion 120 . The perforated portion 120 is not essential. Therefore, the foil 100 may be entirely formed of the non-perforated portion 110 .

[0057] (Second embodiment)

[0058] use Figure 4 This embodiment is a modification of the first embodiment, and components identical to those described in the first embodiment and / or components having the same functions are denoted by the same reference numerals as much as possible, and detailed descriptions thereof are omitted.

[0059] The first foil pressing member 24 has two groups of pressing portions 240 and supporting portions 241. Here, one group of pressing portions 240 and supporting portions 241 presses the non-perforated portion 110 in the area including the side end 112, and the other group of pressing portions 240 and supporting portions 241 presses the non-perforated portion 110 in the area including the side end 114. Therefore, the pressing portion 240 branches into two branches and presses the area (non-perforated portion 110) including the side ends 112 and 114 of the foil 100. At this time, it is preferred that the pressing portion 240 presses the area (non-perforated portion 110) including the side ends 112 and 114 of the foil 100 with a surface that is the same as or smaller than the width of each non-perforated portion 110.

[0060] Therefore, the set of the pressing portion 240 and the supporting portion 241 according to the present embodiment is an example in which the non-perforated portion 110 in the widthwise central portion of the foil 100 is not pressed.

[0061] The second foil pressing member 26 has two groups of pressing portions 260 and supporting portions 261. Here, one group of pressing portions 260 and supporting portions 261 presses the non-perforated portion 110 in the area including the side end 112, and the other group of pressing portions 260 and supporting portions 261 presses the non-perforated portion 110 in the area including the side end 114. Therefore, the pressing portion 260 branches into two branches and presses the area (non-perforated portion 110) including the side ends 112 and 114 of the foil 100. At this time, it is preferred that the pressing portion 260 presses the area (non-perforated portion 110) including the side ends 112 and 114 of the foil 100 with a surface that is the same as or smaller than the width of each non-perforated portion 110.

[0062] Therefore, the set of the pressing portion 260 and the supporting portion 261 according to the present embodiment is an example in which the non-perforated portion 110 in the widthwise central portion of the foil 100 is not pressed.

[0063] In this case, the first air cylinder 244 may be formed as one to move the two pressing parts 240 or may be provided separately for each pressing part 240. Similarly, the second air cylinder 264 may be formed as one to move the two pressing parts 260 or may be provided separately for each pressing part 260.

[0064] For example, preferably, the sliding resistance of the combination of the pressing part 240 and the supporting part 241 of the first foil pressing part 24 on the upstream side to the non-perforated part 110 of the foil 100 is greater than the sliding resistance of the combination of the pressing part 260 and the supporting part 261 of the second foil pressing part 26 on the downstream side to the non-perforated part 110 of the foil 100.

[0065] The conveying device 12 according to this embodiment conveys the foil 100 in a predetermined direction while pressing the common non-perforated portion 110 of the foil 100 in a linear manner at two locations separated in the longitudinal direction (a pair of the pressing portion 240 and the supporting portion 241, and a pair of the pressing portion 260 and the supporting portion 261). In this embodiment, there are two pairs of pressing portions 240 and 241, and two pairs of pressing portions 260 and 261. Therefore, the foil 100 is conveyed in a predetermined direction while pressing the common non-perforated portion 110 in a linear manner at two locations along the longitudinal direction, for a total of four locations across two non-perforated portions 110. Therefore, vibration of the foil 100 is suppressed, and the non-perforated portion 110 of the foil 100 is less likely to deviate from the conveying direction due to the tension applied in the conveying direction. Therefore, the foil 100 is conveyed in the conveying direction while its meandering is suppressed.

[0066] Therefore, according to this embodiment, it is possible to provide a conveying device 12 for conveying the foil 100 to the corrugation applying unit 14 while suppressing meandering when conveying the led-out foil 100 in a predetermined direction, and a corrugation applying device 10 for the foil 100 including the conveying device 12 .

[0067] Furthermore, by utilizing the guide members 28 a and 28 b , the led-out foil 100 can be conveyed to the corrugation applying unit 14 in a predetermined direction while further suppressing meandering.

[0068] In addition, in this embodiment, the number of groups of the pressing portion 240 and the supporting portion 241 of the first foil pressing member 24 and the number of groups of the pressing portion 260 and the supporting portion 261 of the second foil pressing member 26 are respectively two, and the pressing portions 240 and 260 are bifurcated. Either the number of groups of the pressing portion 240 and the supporting portion 241 of the first foil pressing member 24 or the number of groups of the pressing portion 260 and the supporting portion 261 of the second foil pressing member 26 can be one group. That is, when the side end region of the foil 100 including the pair of side ends 112 and 114 is the non-perforated portion 110, it is sufficient as long as at least one of the pressing portion 240 of the first foil pressing member 24 and the pressing portion 260 of the second foil pressing member 26 branches into two branches so as to be able to press the side end region of the foil 100. In this case, the foil 100 is also prevented from being retained between the first foil pressing member 24 and the second foil pressing member 26. Preferably, the sliding resistance of the pressing portion 240 and the supporting portion 241 of the first foil pressing member 24 against the non-perforated portion 110 of the foil 100 is greater than the sliding resistance of the pressing portion 260 and the supporting portion 261 of the second foil pressing member 26 against the non-perforated portion 110 of the foil 100. Therefore, appropriate tension can be applied to the foil 100 between the first foil pressing member 24 and the second foil pressing member 26 in the conveying direction, which can prevent the foil 100 from being retained between the first foil pressing member 24 and the second foil pressing member 26 and being deflected in the conveying direction.

[0069] (Third embodiment)

[0070] use Figure 5 This embodiment is a modification of the first and second embodiments, and components identical to those described in the first and second embodiments and / or components having the same functions are denoted by the same reference numerals whenever possible, and detailed descriptions thereof are omitted.

[0071] The first foil pressing member 24 includes three sets of pressing portions 240 and supporting portions 241. One set of pressing portions 240 and supporting portions 241 presses the non-perforated portion 110 in the region including the side ends 112. One of the remaining two sets of pressing portions 240 and supporting portions 241 presses the non-perforated portion 110 in the region including the side ends 114. The remaining set of pressing portions 240 and supporting portions 241 presses the non-perforated portion 110 in the widthwise center portion between the side ends 112 and 114. Thus, the pressing portion 240 branches into three branches, for example, to press the non-perforated portion 110 in the region including the side ends 112 and 114 of the foil 100, as well as the non-perforated portion 110 in the widthwise center portion. At this time, it is preferable that the pressing portion 240 presses the three non-perforated portions 110 of the foil 100 with a surface having the same width as or smaller than the width of each non-perforated portion 110 .

[0072] The second foil pressing member 26 includes three sets of pressing portions 260 and supporting portions 261. One set of pressing portions 260 and supporting portions 261 presses the non-perforated portion 110 in the region including the side ends 112. One of the remaining two sets of pressing portions 260 and supporting portions 261 presses the non-perforated portion 110 in the region including the side ends 114. The remaining set of pressing portions 260 and supporting portions 261 presses the non-perforated portion 110 in the region in the widthwise center between the side ends 112 and 114. Thus, the pressing portion 260 branches into three branches, for example, to press the non-perforated portion 110 in the region including the side ends 112 and 114 of the foil 100, as well as the non-perforated portion 110 in the widthwise center. At this time, it is preferable that the pressing portion 260 presses the three non-perforated portions 110 of the foil 100 with a surface having the same width as or smaller than the width of each non-perforated portion 110 .

[0073] In this case, the first air cylinder 244 may be formed as a single cylinder to move the three pressing parts 240 or may be provided separately for each pressing part 240. Similarly, the second air cylinder 264 may be formed as a single cylinder to move the three pressing parts 260 or may be provided separately for each pressing part 260.

[0074] The conveying device 12 according to this embodiment conveys the foil 100 in a predetermined direction while pressing the common non-perforated portion 110 of the foil 100 in a linear manner at two locations separated in the longitudinal direction (a combination of the pressing portion 240 and the supporting portion 241, and a combination of the pressing portion 260 and the supporting portion 261). In this embodiment, there are three groups of pressing portions 240 and the supporting portion 241, and three groups of pressing portions 260 and the supporting portion 261, respectively. Therefore, the foil 100 is conveyed in a predetermined direction while pressing in a linear manner at two locations on one non-perforated portion 110, and at six locations on three non-perforated portions 110, respectively. Therefore, vibration of the foil 100 is suppressed, and the non-perforated portion 110 of the foil 100 is less likely to deviate from the conveying direction due to the tension applied in the conveying direction. Therefore, the foil 100 is conveyed in the conveying direction while its meandering is suppressed.

[0075] Therefore, according to this embodiment, it is possible to provide a conveying device 12 for the foil 100 that can convey the drawn foil 100 to the corrugation applying unit 14 while suppressing meandering when conveying the foil 100 in a predetermined direction, and a corrugation applying device 10 for the foil 100 including the conveying device 12 .

[0076] Furthermore, by utilizing the guide members 28 a and 28 b , the led-out foil 100 can be conveyed to the corrugation applying unit 14 in a predetermined direction while further suppressing meandering.

[0077] In addition, in this embodiment, the number of groups of the pressing portion 240 and the supporting portion 241 of the first foil pressing member 24 and the number of groups of the pressing portion 260 and the supporting portion 261 of the second foil pressing member 26 are respectively three, and the pressing portions 240 and 260 are three-branched. Either the number of groups of the pressing portion 240 and the supporting portion 241 of the first foil pressing member 24 or the number of groups of the pressing portion 260 and the supporting portion 261 of the second foil pressing member 26 can be one group or two groups. That is, when the side end region of the foil 100 including a pair of side ends 112 and 114 is a non-perforated portion 110, it is sufficient as long as at least one of the pressing portion 240 of the first foil pressing member 24 and the pressing portion 260 of the second foil pressing member 26 branches into three branches and is able to press the side end region of the foil 100. In this case, the foil 100 is also prevented from being retained between the first foil pressing member 24 and the second foil pressing member 26. Therefore, it is preferable that the sliding resistance of the pressing portion 240 and the supporting portion 241 of the first foil pressing member 24 against the non-perforated portion 110 of the foil 100 is greater than the sliding resistance of the pressing portion 260 and the supporting portion 261 of the second foil pressing member 26 against the non-perforated portion 110 of the foil 100. Therefore, appropriate tension can be applied to the foil 100 between the first foil pressing member 24 and the second foil pressing member 26 in the conveyance direction, and the foil 100 can be prevented from being retained between the first foil pressing member 24 and the second foil pressing member 26 and being deflected in the conveyance direction.

[0078] In addition, the present invention is not limited to the above-mentioned embodiments, and various modifications can be made during the implementation stage without departing from the main purpose. In addition, the various embodiments can be appropriately combined for implementation, in which case the combined effect can be obtained. Furthermore, the above-mentioned embodiments include various inventions, and various inventions can be extracted by selecting a combination from a plurality of disclosed technical features. For example, even if several technical features are deleted from all the technical features shown in the embodiments, the structure from which the technical features are deleted can also be extracted as an invention if the problem can be solved and the effect can be obtained.
