[0004] [Patent Document 1] Japanese Patent Application Publication No. 7-287464 Summary of the Invention [Problem to be solved by the invention]

[0005] In the structure shown in the device of Patent Document 1, when a long sheet is conveyed, there is a problem in that the sheet may lose its orientation before contacting the roller, causing fine wrinkles.

[0006] An object of the present invention is to provide a conveying device that can prevent wrinkles from occurring even when conveying a long sheet. [Means for solving the problem]

[0007] A conveying device according to one embodiment of the present invention is a conveying device that conveys a sheet-like workpiece having a first surface in a conveying direction, and is equipped with a conveying roller, a first guide member, a second guide member, a third guide member, and a fourth guide member.

[0008] The conveying roller is arranged to be able to contact the first surface of the workpiece and to be able to rotate about its axis. The first guide member is arranged opposite the conveying roller in the opposite direction to the conveying direction, at one end in the direction parallel to the axis, and is able to contact the first surface of the workpiece. The second guide member is arranged at one end in the direction parallel to the axis and is arranged at a position where it sandwiches the workpiece with a gap from the first guide member.

[0012] A transport device according to an embodiment of the present invention will be described with reference to the drawings.

[0013] (sheet electrode 90) Fig. 1 shows three views of a sheet electrode conveyed by a conveying device according to an embodiment of the present invention. Fig. 1 shows a plan view, a cross-sectional view in the width direction, and a cross-sectional view in the longitudinal direction. The plan view shows a cutaway view of a portion of the sheet electrode in the longitudinal direction.

[0014] The sheet electrode 90 has an elongated shape and has a planar first surface F91 and a planar second surface F92. The sheet electrode 90 has a first side end WE91 and a second side end WE92 that are parallel to the longitudinal direction. The sheet electrode corresponds to the "workpiece" of the present invention. Note that, although the present embodiment uses the sheet electrode 90 as an example of the workpiece, the configuration of this embodiment can be applied to any conveying device that conveys a film or the like that causes a phenomenon similar to that of the sheet electrode 90 described below.

[0015] The sheet electrode 90 includes a metal foil 900 and an electrode material layer 990. The sheet electrode 90 is used, for example, as an electrode for a solid electrolytic capacitor.

[0016] The metal foil 900 is made of, for example, aluminum foil and has a thickness that allows it to be easily deformed.

[0017] The electrode material layers 990 are formed on both sides of the metal foil 900. One surface of the electrode material layer 990 corresponds to the first surface F91, and the other surface of the electrode material layer 990 corresponds to the second surface F92.

[0018] The electrode material layer 990 has a shape that does not reach the first side end WE91 or the second side end WE92 in the width direction of the metal foil 900.

[0019] With this configuration, the sheet electrode 90 has an electrode material formed portion 991 in the center in the width direction, where the electrode material layer 990 is formed on both sides of the metal foil 900. Furthermore, the sheet electrode 90 has an electrode material non-formed portion 9921 made up of only the metal foil 900 at a first side end WE91 in the width direction, and an electrode material non-formed portion 9922 made up of only the metal foil 900 at a second side end WE92 in the width direction.

[0020] The thickness D992 of the electrode material non-forming portions 9921 and 9922 corresponds to the thickness of the metal foil 900, and the thickness D991 of the electrode material formed portion 991 corresponds to the thickness of the laminate of the metal foil 900 and the two electrode material layers 990. Therefore, the thickness D991 of the electrode material formed portion 991 is greater than the thickness D992 of the electrode material non-forming portions 9921 and 9922.

[0021] The conveying device 10, which will be described next, conveys the sheet electrode 90 having such a shape.

[0022] (Transport device 10) Fig. 2 is a perspective view of the appearance of a conveying device according to an embodiment of the present invention, Fig. 3 is a side view of a conveying device according to an embodiment of the present invention, and Fig. 4 is a top view (plan view) of a conveying device according to an embodiment of the present invention.

[0023] As shown in Figures 2, 3, and 4, the conveying device 10 includes a conveying roller 20, a first guide member 311, a second guide member 312, a third guide member 321, a fourth guide member 322, a first position control member 41, and a second position control member 42.

[0024] The conveying roller 20 is cylindrical or columnar and has an axis AX20 and a circumferential surface 200. The circumferential surface of a cylindrical or columnar shape is a curved surface that forms the side surface of the cylindrical or columnar shape. The conveying roller 20 is disposed so that the axis AX20 is perpendicular to the vertical direction. The conveying roller 20 is disposed rotatably about the axis AX20 relative to a support mechanism (not shown), for example, using an axial rod 290 that is parallel to and overlaps the axis AX20.

[0025] The first guide member 311, the second guide member 312, the third guide member 321, and the fourth guide member 322 are cylindrical or columnar rods, and are arranged to be rotatable in the same manner as the conveying roller 20. The diameters of the first guide member 311, the second guide member 312, the third guide member 321, and the fourth guide member 322 are smaller than the diameter of the conveying roller 20. The lengths of the first guide member 311, the second guide member 312, the third guide member 321, and the fourth guide member 322 are shorter than the length of the conveying roller 20, for example, shorter than half the length of the conveying roller 20.

[0026] The first guide member 311, the second guide member 312, the third guide member 321, and the fourth guide member 322 are arranged so that the direction in which they extend is parallel to the axis AX20 of the transport roller 20.

[0027] The first guide member 311 , the second guide member 312 , the third guide member 321 , and the fourth guide member 322 face the circumferential surface 200 of the transport roller 20 .

[0028] The first guide member 311, the second guide member 312, the third guide member 321, and the fourth guide member 322 are arranged in the opposite direction to the conveyance direction of the sheet electrode 90 (upstream in the conveyance direction of the sheet electrode 90).

[0029] The first guide member 311, the second guide member 312, the third guide member 321, and the fourth guide member 322 are disposed at positions spaced a predetermined distance from the circumferential surface 200 of the conveying roller 20. In other words, as shown in Fig. 3, for example, the first guide member 311, the second guide member 312, the third guide member 321, and the fourth guide member 322 are disposed at positions spaced a distance L from the axis AX20 of the conveying roller 20.

[0030] The first guide member 311 is disposed at a position on one end side of the transport roller 20 in a direction parallel to the axis AX20.

[0031] The second guide member 312 is disposed at a position on one end side of the conveying roller 20 in a direction parallel to the axis AX20, and runs parallel to the first guide member 311. The second guide member 312 is disposed with a gap GAP (see FIG. 5) between it and the first guide member 311.

[0032] The third guide member 321 is disposed at a position on the other end side of the conveyance roller 20 in a direction parallel to the axis AX20. In the vertical direction, the third guide member 321 is disposed at the same position as the first guide member 311. The third guide member 321 and the first guide member 311 are spaced a predetermined distance apart.

[0033] The fourth guide member 322 is disposed at a position on the other end side of the conveyance roller 20 in a direction parallel to the axis AX20, and runs parallel to the third guide member 321. In the vertical direction, the fourth guide member 322 is disposed at the same position as the second guide member 312. There is a predetermined distance between the fourth guide member 322 and the second guide member 312. The fourth guide member 322 is disposed with a gap GAP (see FIG. 5) between it and the third guide member 321.

[0034] The gap GAP between the first guide member 311 and the second guide member 312 and the gap GAP between the third guide member 321 and the fourth guide member 322 are larger than the thickness of the sheet electrode 90, more specifically, the thickness D991 of the electrode material formed portion 991. However, the gap GAP is not significantly larger than the thickness D991. When electrode material non-formed portions 9921 and 9922 of the sheet electrode 90 (described later) are curved vertically downward, the distance between the upper and lower ends of the sheet electrode 90 may become D9911, which is larger than the thickness D991. The gap GAP between the first guide member 311 and the second guide member 312 and the gap GAP between the third guide member 321 and the fourth guide member 322 are preferably larger than D991 and smaller than the thickness D9911, and more preferably approximately the same as the thickness D9911.

[0035] In the width direction of the sheet electrode 90, which is perpendicular to the conveying direction of the sheet electrode 90, the first guide member 311 and the second guide member 312 are spaced apart from the third guide member 321 and the fourth guide member 322. This allows the multiple guide members to hold down only the widthwise ends of the sheet electrode 90, where wrinkles may occur. This more effectively suppresses wrinkles.

[0036] The first position control member 41 includes a first arm 411 and a first weight 412 .

[0037] The first arm 411 is made of a rigid body such as metal, etc. The first arm 411 is disposed on one end side of the transport roller 20 in a direction parallel to the axis AX20, and further outward than the one end of the transport roller 20.

[0038] The first arm 411 is disposed rotatably with respect to the shaft 290 of the conveying roller 20 .

[0039] The first arm 411 has a first front portion that extends from the transport roller 20 toward the first guide member 311 and the second guide member 312. The first front portion is connected to the first guide member 311 and the second guide member 312.

[0040] With this configuration, the first guide member 311 and the second guide member 312 are positioned rotatably with respect to the transport roller 20 while maintaining a constant distance to the transport roller 20.

[0041] The first arm 411 has a first rear portion formed on the opposite side to the first guide member 311 and the second guide member 312 with respect to the transport roller 20. A first weight 412 is connected to the first rear portion.

[0042] In this case, the structure including the first guide member 311, the second guide member 312, and the first position control member 41 (the first arm 411 and the first weight 412) is configured in a shape such that the center of gravity G40 coincides with the shaft 290 (the center of gravity G40 is on the axis of the conveyance roller 20). The center of gravity G40 is a position where, for example, the creeping distance from the tip of the first guide member 311 to the center of gravity G40 and the creeping distance from the tip of the first position control member 41 to the center of gravity G40 are equal.

[0043] The second position control member 42 includes a second arm 421 and a second weight 422 .

[0044] The second arm 421 is made of a rigid body such as metal. The second arm 421 has, for example, the same shape as the first arm 411. The second arm 421 is disposed on the other end side of the conveyance roller 20 in a direction parallel to the axis AX20, and further outward than the other end of the conveyance roller 20.

[0045] The second arm 421 is disposed rotatably with respect to the shaft 290 of the conveying roller 20 .

[0046] The second arm 421 has a second front portion that extends from the transport roller 20 toward the third guide member 321 and the fourth guide member 322. The second front portion is connected to the third guide member 321 and the fourth guide member 322.

[0047] With this configuration, the third guide member 321 and the fourth guide member 322 are positioned rotatably with respect to the transport roller 20 while maintaining a constant distance to the transport roller 20.

[0048] Second arm 421 has a second rear portion formed on the opposite side of third guide member 321 and fourth guide member 322 with respect to conveyance roller 20. Second weight 422 is connected to the rear portion of second arm 421. Second weight 422 has the same shape as first weight 412, for example.

[0049] In this case, the structure including the third guide member 321, the fourth guide member 322, and the second position control member 42 (the second arm 421 and the second weight 422) is configured in a shape such that the center of gravity G40 coincides with the shaft 290.

[0050] (Conveyance of the Sheet Electrode 90 by the Conveying Device 10) 2, 3, and 4, when the sheet electrode 90 is conveyed by the conveying device 10, the sheet electrode 90 is guided to the lower end of the conveying roller 20 so that the first side end WE91 passes between the first guide member 311 and the second guide member 312 and the second side end WE92 passes between the third guide member 321 and the fourth guide member 322. At this time, the sheet electrode 90 is arranged such that the first surface F91 faces upward (toward the first guide member 311 and the third guide member 321) and the second surface F92 faces downward (toward the second guide member 312 and the fourth guide member 322).

[0051] The sheet electrode 90 guided to the conveying roller 20 flows with the first surface F91 in contact with the circumferential surface 200 of the conveying roller 20, and is discharged vertically above the conveying roller 20 as the conveying roller 20 rotates.

[0052] 5(A) and 5(B) are diagrams showing an example of the shape change when the sheet electrode passes through the positions where multiple guide members are arranged. Figures 5(A) and 5(B) are views seen from the side where the sheet electrode 90 is inserted. Figure 5(A) shows the state of the sheet electrode before it passes through the positions where multiple guide members are arranged, and Figure 5(B) shows the state of the sheet electrode after it has passed the positions where multiple guide members are arranged.

[0053] The electrode material non-forming portion 9921 of the sheet electrode 90 passes between the first guide member 311 and the second guide member 312, and the electrode material non-forming portion 9922 passes between the third guide member 321 and the fourth guide member 322. The first guide member 311 is disposed vertically above the second guide member 312. The third guide member 321 is disposed vertically above the fourth guide member 322.

[0054] At this time, the first guide member 311 and the third guide member 321 are in contact with the first surface F91 of the sheet electrode 90. For example, the first guide member 311 and the third guide member 321 are in contact with the first surface F91 of the sheet electrode 90 in a state in which a load of approximately 0 N to 0.5 N is applied to the first surface F91 of the sheet electrode 90.

[0055] Because the first guide member 311 and the third guide member 321 are disposed apart, there is an area in the center of the first surface F91 of the sheet electrode 90 that is not in contact with the guide members. This configuration can more effectively prevent wrinkles from occurring.

[0056] With this configuration, the following effects can be obtained.

[0057] As shown in Figure 5(A), before the sheet electrode 90 passes through the arrangement positions of multiple guide members (first guide member 311, second guide member 312, third guide member 321, and fourth guide member 322), the electrode material non-forming portion 9921 and the electrode material non-forming portion 9922 are bent relative to the electrode material forming portion 991.

[0058] More specifically, the electrode material non-forming portion 9921 curves from the end connected to the electrode material formed portion 991 toward the end corresponding to the first side end WE91 toward the second surface F92, i.e., toward the second guide member 312. The electrode material non-forming portion 9922 curves from the end connected to the electrode material formed portion 991 toward the end corresponding to the second side end WE92 toward the second surface F92, i.e., toward the fourth guide member 322.

[0059] This is due to the way the sheet electrode 90 is wound around the supply roller 80 that supplies the sheet electrode 90 to the conveying device 10 (see FIG. 6).

[0060] When the sheet electrode 90 is in this state, the first guide member 311 and the third guide member 321 are brought into contact with the first surface F91 and the sheet electrode 90 is transported, whereby the curvature of the sheet electrode 90 is corrected as shown in Fig. 5(B) . As a result, the sheet electrode 90 becomes flat in the entire width direction from the first side end WE91 to the second side end WE92.

[0061] In this case, by providing the second guide member 312 facing the first guide member 311 and the fourth guide member 322 facing the third guide member 321, the curvature of the sheet electrode 90 can be corrected more reliably.

[0062] The sheet electrode 90, whose curvature has been corrected in this manner, is guided to the conveying roller 20 while maintaining a flat state. As a result, even if the sheet electrode 90 abuts against the circumferential surface of the conveying roller 20, the occurrence of wrinkles in the sheet electrode 90 is suppressed.

[0063] In this way, the conveying device 10 can prevent wrinkles from occurring in the sheet electrode 90 even when conveying a long sheet electrode 90.

[0064] Furthermore, the conveying device 10 includes a first position control member 41 and a second position control member 42. By including the first position control member 41 and the second position control member 42, the position of the first guide member 311 can be appropriately adjusted by the first weight 412, and the position of the third guide member 321 can be appropriately adjusted by the second weight 422, depending on the conveying state of the sheet electrode 90.

[0065] This allows the conveying device 10 to stably apply a constant load to the sheet electrode 90. Therefore, even when conveying a long sheet electrode 90, the conveying device 10 can prevent wrinkles from occurring in the sheet electrode 90.

[0066] In this case, there is an appropriate distance L (see FIG. 3) between the multiple guide members (first guide member 311, second guide member 312, third guide member 321, and fourth guide member 322) in the conveying direction of the sheet electrode 90 and the position on the conveying roller 20 where the sheet electrode 90 first comes into contact. For example, the distance L is 100 mm to 200 mm.

[0067] By configuring the conveying device 10 using this distance L, it is possible to more reliably suppress wrinkles in the sheet electrode 90. Note that the distance L can be set appropriately depending on the thickness of the sheet electrode 90, the diameter of the conveying roller 20, the tension applied to the sheet electrode 90 during conveyance, etc.

[0068] Furthermore, the multiple guide members (first guide member 311, second guide member 312, third guide member 321, and fourth guide member 322) are preferably arranged so as to overlap the electrode material forming portion 991 of the sheet electrode 90. The length of the portion overlapping the electrode material forming portion 991 is preferably, for example, 2 mm or more. The length of the portion overlapping the electrode material forming portion 991 can also be set appropriately based on the transport state of the sheet electrode 90, etc.

[0069] With this configuration, the conveying device 10 can more reliably prevent the sheet electrode 90 from wrinkling.

[0070] Furthermore, the transport device 10, being provided with the first position control member 41 and the second position control member 42, can achieve the following advantageous effects.

[0071] 6(A) and 6(B) are side views showing the state in which the sheet electrodes are transported from the supply roller through the transport device. The amount (length) of the sheet electrodes remaining on the supply roller differs between Fig. 6(A) and Fig. 6(B). Fig. 6(B) shows a case in which the amount of remaining sheet electrodes is smaller (shorter) than Fig. 6(A).

[0072] As shown in Figures 6A and 6B, the positional relationship (horizontal distance DISH and vertical distance DISV) between the conveyance roller 20 and the supply roller 80 of the conveyance device 10 is constant. In this case, if the amount of sheet electrode 90 remaining on the supply roller 80 varies, the positional relationship between the conveyance roller 20 and the position at which the sheet electrode 90 is sent from the supply roller 80 changes, as shown in Figures 6A and 6B. In this case, if the centers of gravity of the first position control member 41 and the second position control member 42 are not positioned appropriately, the load applied to the sheet electrode 90 by the first guide member 311 and the load applied to the sheet electrode 90 by the third guide member 321 will differ, causing wrinkles.

[0073] Therefore, the transport device 10 is configured so that the center of gravity G40 of the first position control member 41 and the second position control member 42 coincides or substantially coincides with the central axis of rotation.

[0074] As a result, even if the discharge position of the sheet electrode 90 from the supply roller 80 changes, the conveying device 10 can always apply the same load to the sheet electrode 90 from the first guide member 311 and the third guide member 321, thereby further suppressing the occurrence of wrinkles.

[0075] Therefore, the conveying device 10 can more stably prevent the sheet electrode 90 from wrinkling, regardless of the position at which the sheet electrode 90 is discharged from the supply roller 80.

[0076] In the above description, the second guide member 312 and the fourth guide member 322 are not in contact with the sheet electrode 90. However, it is also possible to position the second guide member 312 and the fourth guide member 322 so that they are in contact with the sheet electrode 90. In this case, the load applied by the second guide member 312 to the sheet electrode 90 is smaller than the load applied by the first guide member 311 to the sheet electrode 90, and the load applied by the fourth guide member 322 to the sheet electrode 90 is smaller than the load applied by the third guide member 321 to the sheet electrode 90. This allows the conveyance device 10 to suppress the occurrence of wrinkles in the sheet electrode 90.

[0077] In the above description, the first guide member 311, the second guide member 312, the third guide member 321, and the fourth guide member 322 are described as being rotatable cylindrical or columnar rods. However, the shapes of the first guide member 311, the second guide member 312, the third guide member 321, and the fourth guide member 322 are not limited to these. For example, they may be non-rotating cylindrical or columnar rods or flat plates. In this case, however, it is preferable that at least the surfaces of the first guide member 311 and the third guide member 321 that come into contact with the sheet electrode 90 have low frictional resistance so that the sheet electrode 90 can slide when the sheet electrode 90 is being transported. Furthermore, the surface referred to here may be a flat surface or a curved surface.

[0078] Furthermore, as in the above-described configuration, it is preferable that the conveying device 10 is disposed immediately after the supply roller 80. In other words, it is preferable that no process (device) that performs other processing (processing, etc.) on the sheet electrode 90 is sandwiched between the supply roller 80 and the conveying device 10.

[0079] In this case, a process (device) for performing other processing on the sheet electrode 90 (various processing such as heat treatment, composite coating, cutting, etc.) is disposed downstream of the conveying device 10 on the conveying path of the sheet electrode. This allows the process (device) for performing other various processing on the sheet electrode 90 to be performed using the sheet electrode 90 in which the occurrence of wrinkles is suppressed. This makes it possible to suppress the occurrence of defects during the manufacture of electronic components (e.g., solid electrolytic capacitors) using the sheet electrode 90, the occurrence of electronic components with poor electrical properties, and the occurrence of electronic components with insufficient reliability.
