Abstract

To provide a wound body manufacturing device which is less likely to cause deflection in a foil material and can cut the foil material at a desired position when cutting the foil material after winding the foil material to form the wound body. [Solution] The wound body manufacturing device includes a winding core around which foil material can be wound as a wound body, an adjustment unit capable of adjusting the amount of foil material supplied toward the winding core, a guide surface provided between the winding core and the adjustment unit that guides the foil material from the adjustment unit side toward the winding core, a guide that is adjustable so that the foil material comes into contact with the guide surface, and a control unit. The control unit positions the guide surface at a first position where a virtual extension of the guide surface toward the downstream side intersects with the winding core from the start to the end of winding of the foil material around the winding core, and after winding of the wound body is completed, the adjustment unit presses the foil material so that it can be supplied toward the guide, and then moves the guide surface to a second position where a virtual extension of the guide surface toward the downstream side comes into contact with the wound body.

Description

[Technical Field]

[0001] The present invention relates to an apparatus for manufacturing a wound body. [Background technology]

[0002] For example, a wound body such as a honeycomb body obtained by stacking and winding a corrugated sheet of a predetermined length and a flat foil material supplied from a roll, for example, is obtained by cutting the flat foil material after winding the corrugated sheet around the axis of a winding core. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-021989 Summary of the Invention [Problem to be solved by the invention]

[0004] In this case, it is desirable to cut the foil material with a cutter positioned perpendicular or nearly perpendicular to the foil material, rather than cutting the foil material from a direction inclined relative to the cutter. For this reason, after the corrugated sheet is wound up and the rotation of the winding core is stopped, the guide position of the flat foil material is shifted so that the tangential direction of the winding body coincides or nearly coincides with the direction in which the foil material is fed, and the foil material is cut with the cutter from a direction perpendicular or nearly perpendicular to the foil material.

[0005] However, if the guide position of the foil material is shifted so that the tangential direction of the wound body and the direction in which the foil material is fed are aligned or approximately aligned, the distance between the end of the guide surface and the tangential direction of the wound body becomes closer than before the guide surface was shifted, which can cause the foil material to bend, making it difficult to cut the foil material at the desired location with a cutter.

[0006] The present invention aims to provide a wound body manufacturing device that is less likely to cause deflection in the foil material when cutting the foil material after winding the supplied foil material to create a wound body, and that can cut the foil material at a desired position. [Means for solving the problem]

[0007] a base having a guide surface that is provided between the winding core and the adjustment unit and that extends along the XY plane on the +Z axis direction to guide the foil material from the adjustment unit side to the winding core, and a guide that is adjustable so that the foil material that is supplied downstream in the +X axis direction through the adjustment unit comes into contact with the guide surface according to the position of the guide surface in the Z axis direction; an actuator that is provided on the base and that moves the guide surface and the guide together in directions along the ±Z axis directions; a cutter that is provided between the guide on the base and the winding core and that is capable of cutting the foil material wound around the winding body; and a control unit that controls the movement of the winding core, the adjustment unit, the actuator, and the cutter. The control unit controls the actuator to position the guide surface at a first position where a surface of the guide surface, which is a virtual extension of the XY plane of the guide surface in the +X-axis direction on the downstream side, intersects with the winding core or is kept close to the winding core within a predetermined distance range in the Z-axis direction, from the start of winding the foil material around the winding core to the end of winding. After winding of the wound body is completed, the control unit controls the adjustment unit to hold the foil material so that it can be supplied toward the guide, and then controls the actuator to move the guide surface in the -Z-axis direction to move the guide surface to a second position where a surface of the guide surface, which is a virtual extension of the XY plane of the guide surface in the +X-axis direction on the downstream side, contacts the wound body or is in the vicinity of that position, thereby applying tension to the foil material. With the tension applied, the control unit controls the cutter to cut the foil material between the guide and the wound body with the cutter. [Effects of the Invention]

[0008] According to the present invention, a rolled body manufacturing device can be provided that, after winding supplied foil material to create a rolled body, when performing a process to cut the foil material, is less likely to cause bending in the foil material and can cut the foil material at a desired position.

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] An apparatus 10 for manufacturing a wound body (metal substrate) 110 according to one embodiment will be described with reference to FIGS. 1 to 11. FIG.

[0012] 1 shows a schematic perspective view of a wound body 110 wound using a manufacturing apparatus 10. The wound body 110 is formed by winding a strip-shaped flat sheet 120 and a corrugated sheet 130 placed on top of the flat sheet 120 in a roll shape around the axis of a winding core 14 that is perpendicular to the conveying direction of the flat sheet 120 and the corrugated sheet 130. The flat sheet 120 is formed as a flat plate. The corrugated sheet 130 is formed as a plate that has been given a generally sinusoidal wave shape with a predetermined pitch and a predetermined amplitude, for example.

[0013] The flat plate 120 and the corrugated plate 130 according to this embodiment may or may not have through holes (air passages) formed therein. For example, through holes may be formed only in the flat plate 120.

[0014] An example of the wound body 110 according to this embodiment is a honeycomb body that supports a catalyst for purifying exhaust gas. The wound body (honeycomb body) 110 is used as a component housed in a cylindrical outer casing of a catalytic converter for purifying exhaust gas, for example.

[0015] As an example, a metal foil material such as stainless steel is used as the material for the flat plate 120 and the corrugated plate 130. As an example, the thickness of the metal foil material is allowed to be from about several tens of μm to several mm.

[0016] Although not shown, the corrugated sheet 130 in a corrugated state is supplied, for example, as a corrugated sheet wound body, with the overall length of the corrugated sheet 130 or the number of waves (number of crests) of the corrugated sheet 130 being set in advance within a predetermined range. The corrugated sheet 130 is supplied, for example, cut to a fixed dimension in the longitudinal direction. For example, one corrugated sheet wound body is required to manufacture one wound body 110, and these are supplied in order to be replaceable. It is also preferable that the corrugated sheet 130 is sufficiently long for the length required for one wound body 110, as in the case of a flat sheet roll 82 described below, and then cut to an appropriate length by, for example, a cutter 20.

[0017] Fig. 2 is a schematic top view of the manufacturing apparatus 10 for the wound body 110. Fig. 3 is a front view of the manufacturing apparatus 10 for the wound body 110, as seen from the direction indicated by arrow III in Fig. 2. Figs. 4 to 8 sequentially show a series of operations following those of the manufacturing apparatus 10 in Fig. 3. Note that the cutter 16 and the corrugated sheet supply unit 28 are not shown in Fig. 2.

[0018] 2 to 8, an XYZ Cartesian coordinate system is used. The +X axis direction is the direction in which the flat sheet 120 to be wound is guided (transported) when being wound around the corrugated sheet 130. In other words, the +X axis direction is the direction in which the flat sheet 120 to be wound moves from the upstream side to the downstream side. The +Y axis direction is the direction toward the top of FIG. 2, and is along the depth direction (width direction) perpendicular to the paper surface of FIGS. 3 to 8. The +Z axis direction is the direction toward the top of the paper surface of FIG. 2, and is the direction toward the top of FIGS. 3 to 8.

[0019] FIG. 9 shows a schematic block diagram of the manufacturing apparatus 10 for the wound body 110 shown in FIGS.

[0020] As shown in Figures 2 to 9, the manufacturing apparatus 10 for the wound body 110 has a first housing 12, a winding core 14, a cutter 16, a second housing 18, an adjustment section 20, a base unit 22, a flat plate holder 24, a flat plate supply section 26, a corrugated plate supply section 28, and a control section 30.

[0021] The first housing 12 is fixed, for example, to the lower surface (XY plane) of the paper in FIG. 2, or to the surface on the depth side of the paper in FIG. 2 (ZX plane).

[0022] The first housing 12 is provided with, for example, a core 14 and a cutter 16.

[0023] The winding core 14 is formed as a metal rod having a diameter of, for example, about 5 mm, by processing a highly rigid and tough steel material such as SUS440C or SKD11. The winding core 14 is supported in the housing 12 so as to be rotatable about a predetermined central axis C. The predetermined central axis C is provided parallel to the Y axis. The length of the winding core 14 in the Y axis direction is formed to be greater than the width of the flat plate 120 and the corrugated plate 130 in the Y axis direction. The winding cores 14 may be a pair that can move close to and apart in the Y axis direction. It is preferable that the position of the winding core 14 in the X axis direction and the position of the Z axis direction do not change, for example.

[0024] The winding core 14 has, for example, a slit 14a extending in the Y-axis direction. For example, with the corrugated sheet 130 placed on the flat sheet 120, the flat sheet 120 is placed in the slit 14a of the winding core 14 from the +X-axis direction end side of the flat sheet 120, and the +X-axis direction end of the corrugated sheet 130 is brought into contact with or close to the winding core 14 on the +Z-axis direction side of the flat sheet 120. Then, the winding core 14 is rotated around its axis to form a substantially cylindrical metal substrate (wound body) 110. Therefore, the winding core 14 can wind the supplied foil material (flat sheet 120 and / or corrugated sheet 130) as the wound body 110. Note that the +X-axis direction end of the corrugated sheet 130 may be placed in the slit 14a of the winding core 14.

[0025] 2 to 8 has a first drive source (actuator) 15 provided on the winding core 14. The first drive source 15 is a motor or the like that rotates the winding core 14 about a predetermined central axis C. The torque or rotation speed of the first drive source 15 is controlled by a control unit 30, for example.

[0026] In this embodiment, the cutter (movable blade) 16 is used together with a receiving portion (fixed blade) 16a. The cutter 16 and receiving portion 16a are provided on the -X-axis direction side of the winding core 14. The cutter 16 and receiving portion 16a are supported on the first housing 12 so as to be movable in the Z-axis direction, i.e., in a direction perpendicular to the X-axis and Y-axis directions. The length of the receiving portion 16a in the depth direction (Y-axis direction) is greater than the width of the corrugated sheet 130 and the flat sheet 120 in the width direction (Y-axis direction). The cutter 16 does not interfere with the movement of the flat sheet 120 and the corrugated sheet 130 in the X-axis direction and is normally on standby in front of or behind the flat sheet 120 in the Y-axis direction. The cutter 16 is formed as, for example, a circular blade movable in the Y-axis direction, and can cut the flat sheet (foil material) 120 with the blade due to, for example, a shear force applied between the cutter 16 and the receiving portion 16a. The length of the receiving portion 16a in the depth direction (Y-axis direction) may be smaller than the width of the corrugated plate 130 and the flat plate 120 in the width direction (Y-axis direction).

[0027] The cutter 16 may be formed as a so-called guillotine cutter with a continuous blade formed in the Y-axis direction larger than the width of the corrugated sheet 130 and the flat sheet 120 in the width direction (Y-axis direction), and may be capable of cutting the flat sheet 120 (and the corrugated sheet 130) by moving in the Z-axis direction. A laser cutter may also be used as the cutter 16. When a laser cutter is used as the cutter 16, the receiving portion 16a may not be necessary.

[0028] The manufacturing apparatus 10 shown in FIGS. 2 to 8 is provided in a first housing 12 and includes a second drive source (actuator) 17a that moves the cutter 16 and the receiving portion 16a, and a second drive source (actuator) 17b that moves the cutter 16 reciprocally in the Y-axis direction. The second drive source 17a may be an air cylinder that moves the cutter 16 and the receiving portion 16a along the Z-axis direction, or a linear actuator (electric cylinder) using a motor and a ball screw. The second drive source 17a may move the cutter 16 and the receiving portion 16a not only along the Z-axis direction, but also along the X-axis direction. The second drive source 17b may be an air cylinder that moves the cutter 16 along the Y-axis direction, or a linear actuator (electric cylinder) using a motor and a ball screw. The second drive source 17a and the second drive source 17b are controlled by a control unit 30.

[0029] The second housing 18 is disposed at a position on the upstream side (-X axis direction side) of the first housing 12. The second housing 12 is fixed to, for example, the lower surface (XY plane) in Figures 3 to 8, or to the depth side surface (ZX plane) in Figures 3 to 8.

[0030] The second housing 18 is provided with, for example, an adjustment section 20, a base unit 22, and a plate holder 24.

[0031] The adjustment unit 20 can adjust the supply amount of the flat plate 120 along the X-axis direction. The adjustment unit 20 has a fixing unit 42 having a sliding surface 42a, a third driving source 44, and a pad 46 provided on the third driving source 44.

[0032] The fixed part 42 is fixed to the floor surface or the second housing 18. The sliding surface 42a of the fixed part 42 is provided at a position on the +Z-axis direction side of the fixed part 42, and guides the flat plate 120 horizontally, for example, in the +X-axis direction. At this time, the flat plate 120 can slide on the sliding surface 42a. A material with excellent wear resistance is used for the sliding surface 42a. It is preferable to use die steel (SKD11), for example, for the sliding surface 42a.

[0033] The third drive source 44 is controlled by the control unit 30. The third drive source 44 may be an air cylinder or a linear actuator that moves the pad 46 in the Z-axis direction. For example, an air cylinder may be used as the third drive source 44. The air cylinder 44 has a cylinder portion 44a fixed to the second housing 18 and a rod portion 44b that is extendable (movable) in the Z-axis direction relative to the cylinder portion 44a.

[0034] A pad 46 is fixed to the end of the rod portion 44b in the −Z-axis direction. The pad 46 is made of a material that has sliding properties relative to the flat plate 120. The pad 46 is made of, for example, ultra-high molecular weight polyethylene (UHPE).

[0035] It is preferable that the sliding surface 42a supports the flat plate 120 over the entire width direction thereof. The pad 46 only needs to support a portion of the flat plate 120 in the width direction thereof, for example, it is sufficient to support the center of the flat plate 120 in the width direction thereof. Of course, the pad 46 may also support the entire width direction of the flat plate 120.

[0036] The base unit 22 is provided between the winding core 14 and the adjustment unit 20. The base unit 22 has a base 52 and a fourth drive source (actuator) 54.

[0037] The base 52 includes a plate-like member 62 having a guide surface 62 a and a guide 64 .

[0038] The guide surface 62a of the plate-like member 62 of the base 52 guides the flat plate 120 from the adjustment unit 20 side to the winding core 14 side along the XY plane on the +Z axis direction side.

[0039] The guide 64 of the base 52 is supported by the plate-shaped member 62. The guide 64 is disposed on the +Z-axis direction side of the guide surface 62a. The flat plate 120 is guided toward the winding core 14 through the gap between the guide surface 62a and the guide 64. The guide 64 is preferably formed as a roller (guide roller) that is long in the Y-axis direction and rotatable around a central axis extending in the Y-axis direction. The length of the guide 64 in the Y-axis direction is formed to be greater than the width of the flat plate 120. The guide 64 can guide the flat plate 120, which is supplied downstream in the +X-axis direction through the adjustment unit 20, so that the flat plate 120 comes into contact with the guide surface 62a, depending on the position of the guide surface 62a of the plate-shaped member 62 in the Z-axis direction.

[0040] The fourth drive source (actuator) 54 is provided on the plate-like member 62 of the base 52, and is capable of moving the guide surface 62a and the guide 64 together in the ±Z axis directions.

[0041] The fourth drive source 54 may be an air cylinder or a linear actuator that moves the plate-like member 62 in the Z-axis direction. For example, an air cylinder may be used as the fourth drive source 54. The air cylinder 54 has a cylinder portion 54a fixed to the second housing 18 and a rod portion 54b that is extendable (movable) in the Z-axis direction relative to the cylinder portion 54a. The plate-like member 62 is fixed to the end of the rod portion 54b in the +Z-axis direction.

[0042] The rod portion 54b relative to the cylinder portion 54a is provided so that, when the rod portion 54b is, for example, fully extended relative to the cylinder portion 54a, a plane obtained by extending the XY plane of the guide surface 62a in the +X-axis direction on the downstream side intersects with the winding core 14 or is kept close to the winding core 14 within a predetermined distance range in the Z-axis direction. Furthermore, when the rod portion 54b relative to the cylinder portion 54a is moved in the −Z-axis direction relative to the cylinder portion 54a and fully retracted, for example, to move the guide surface 62a in the −Z-axis direction, the rod portion 54b positions the guide surface at a second position where a plane obtained by extending the XY plane of the guide surface 62a in the +X-axis direction on the downstream side contacts the wound body 110 or a position nearby.

[0043] The plate presser 24 is provided, for example, on the +Z-axis direction side facing the guide surface 62a of the plate-shaped member 62. The plate presser 24 is preferably provided on the end side of the guide surface 62a that is closest to the +X-axis direction. The plate presser 24 has a fifth drive source 72 and a pad (presser member) 74 provided on the fifth drive source 72.

[0044] The fifth drive source 72 is controlled by the control unit 30. The fifth drive source 72 may be an air cylinder or a linear actuator that moves the pad 74 in the Z-axis direction. For example, an air cylinder may be used as the fifth drive source 72. The air cylinder 72 has a cylinder portion 72a fixed to the second housing 18 and a rod portion 72b that is extendable (movable) in the Z-axis direction relative to the cylinder portion 72a.

[0045] A pad 74 is fixed to the end of the rod portion 72b in the -Z axis direction. The pad 74 preferably presses the flat plate 120 toward the guide surface 62a over the entire width direction or over an area longer than the entire width direction. Therefore, the pad (pressing member) 74 can press the foil material (flat plate 120) against the guide surface 62a. When the pad (pressing member) 74 presses the foil material (flat plate 120) against the guide surface 62a, the foil material (flat plate 120) cannot move relative to the guide surface 62a.

[0046] The flat plate supply unit 26 includes a flat plate roll 82 , a sixth driving source 84 that rotates the flat plate roll 82 , and a guide 86 .

[0047] The flat plate roll 82 is a roll of a foil material (flat plate) 120 having a length sufficiently longer than the length of the flat plate 120 required for one wound body 110.

[0048] The sixth driving source 84 is a motor or the like that rotates the central shaft 82a of the flat roll 82 about its axis. The sixth driving source 84 is controlled by the control unit 30, for example, in terms of torque or rotation speed.

[0049] The guide 86 is provided in, for example, the second housing 18. The guide 86 guides the flat plate 120 supplied from the flat plate roll 82 toward the adjustment unit 20. The guide 86 is preferably formed as a roller (guide roller) that is long in the Y-axis direction and rotatable around a central axis extending in the Y-axis direction. Note that the guide 86 may not be necessary depending on the situation in which the flat plate 120 is guided from the flat plate roll 82 by the guide 64 of the base unit 22.

[0050] The flat plate roll 82 and the sixth driving source 84 of the flat plate supply unit 26 may be provided in the second housing 18, for example, in the same manner as the guide 86.

[0051] The corrugated sheet supply unit 28 is provided in, for example, the second housing 18. The corrugated sheet supply unit 28 has a corrugated sheet roll (not shown).

[0052] The corrugated sheet roll is, for example, a roll formed by winding a corrugated sheet 130 of a predetermined length or a predetermined number of peaks. In this case, one corrugated sheet roll is used to manufacture one wound body 110, and the corrugated sheet 130 of one corrugated sheet roll is replaced after being supplied from the corrugated sheet supply unit 28.

[0053] The corrugated sheet supplying unit 28 may supply a flat sheet, similar to the flat sheet 120 supplied from the flat sheet roll 82, and supply the flat sheet toward, for example, the winding core (core metal) 14 while processing the flat sheet into a corrugated sheet 130. In this case, the corrugated sheet supplying unit 28 or the cutter 20 may cut the flat sheet to be processed into a corrugated sheet 130 supplied from the corrugated sheet supplying unit 28, or the corrugated sheet 130 processed from the flat sheet, at a predetermined position.

[0054] The control unit 30 is configured, for example, by a computer or the like, and includes a processor (processing circuit) and a storage medium. The processor includes any of a CPU (Central Processing Unit), ASIC (Application Specific Integrated Circuit), microcomputer, FPGA (Field Programmable Gate Array), and DSP (Digital Signal Processor). The storage medium may include a main storage device such as a memory, as well as an auxiliary storage device. Examples of storage media include a hard disk drive (HDD), a solid state drive (SSD), a magnetic disk, an optical disk (CD-ROM, CD-R, DVD, etc.), a magneto-optical disk (MO, etc.), and a non-volatile memory such as a semiconductor memory that can be written to and read from at any time.

[0055] The control unit 30 may be provided with only one processor and one storage medium, or may be provided with multiple processors and one storage medium. In the control unit 30, the processor performs processing by executing a program stored in a storage medium or the like. The program executed by the processor of the control unit 30 may be stored in a computer (server) connected to the control unit 30 via a network such as the Internet, or in a server in a cloud environment. In this case, the processor downloads the program via the network.

[0056] In the control unit 30, the control of each of the drive sources 15, 17a, 17b, 44, 54, 72, and 84 is executed by a processor or the like, and the storage medium functions as a data storage unit.

[0057] Furthermore, at least a part of the processing by the control unit 30 may be executed by a cloud server configured in a cloud environment. The infrastructure of the cloud environment is configured by a virtual processor such as a virtual CPU and a cloud memory. In one example, the control of each of the drive sources 15, 17a, 17b, 44, 54, 72, and 84 is executed by the virtual processor, and the cloud memory functions as a data storage unit.

[0058] 9, the manufacturing apparatus 10 for the wound body 110 according to this embodiment includes a transport unit 32 that transports the wound body 110 to a predetermined position after winding. An example of the transport unit 32 is a hand robot. The transport unit 32 is controlled by the control unit 30.

[0059] A series of operations of the manufacturing apparatus 10 for the wound body 110 according to this embodiment will be described below. Fig. 10 shows a flow of a series of operations of the manufacturing apparatus 10 for the wound body 110 according to this embodiment.

[0060] FIG. 11 is a schematic diagram for explaining the distance from the adjustment unit of the wound body manufacturing apparatus shown in FIGS. 5 and 6 to the end of the corrugated sheet.

[0061] 2 and 3, the flat plate 120 is used by being pulled out from, for example, a flat plate roll 82. The control unit 30 controls the sixth drive source 84 to supply the flat plate 120 from the flat plate supply unit 26 to the winding core 14 through the guide 86, between the sliding surface 42a of the adjustment unit 20 and the pad 46, the guide 64, and the guide surface 62a. In addition, the corrugated plate supply unit 28 supplies a corrugated plate 130 to the surface of the flat plate 120 on the +Z axis direction side. For example, with the corrugated plate 130 positioned on the +Z axis direction side of the flat plate 120, the flat plate 120 is placed in the slit 14a of the winding core 14 from the +X axis direction end side of the flat plate 120, and the +X axis direction end of the corrugated plate 130 is brought into contact with or close to the winding core 14 on the +Z axis direction side of the flat plate 120. For this reason, the tip end (end portion on the +X axis direction side) of the corrugated plate 130 is disposed between the flat plate 120 and the winding core 14, for example, on the -Z axis direction side of the winding core 14 (step S10).

[0062] The end face (end face on the +Y-axis direction) on one side in the width direction (Y-axis direction) of the flat plate 120 and the end face (end face on the +Y-axis direction) on one side in the width direction (Y-axis direction) of the corrugated plate 130 are on the same ZX plane. In addition, the end face (end face on the -Y-axis direction) on the other side in the width direction (Y-axis direction) of the flat plate 120 and the end face (end face on the -Y-axis direction) on the other side in the width direction (Y-axis direction) of the corrugated plate 130 are on the same ZX plane. For this reason, it is preferable that both ends in the width direction of the flat plate 120 and the corrugated plate 130 are aligned.

[0063] At this time, the sliding surface 42a is separated from the pad 46, and the guide surface 62a is separated from the pad 74. The cutter 16 and the receiving portion 16a are not in contact with either the flat plate 120 or the corrugated plate 130 due to the control of the 2-1 drive source 17a and the 2-2 drive source 17b by the control unit 30.

[0064] The control unit 30 then controls the fourth drive source (actuator) 54 to maintain a plane, which is an imaginary extension of the XY plane of the guide surface 62a in the downstream +X-axis direction, intersecting with, for example, the winding core 14. Alternatively, the control unit 30 controls the fourth drive source (actuator) 54 to maintain a plane, which is an imaginary extension of the XY plane of the guide surface 62a in the downstream +X-axis direction, close to, within a predetermined distance range in the Z-axis direction, the winding core 14. This position of the guide surface 62a is defined as a first position. The first position does not necessarily require that the plane, which is an imaginary extension of the XY plane of the guide surface 62a in the downstream +X-axis direction, intersect with the winding core 14.

[0065] Then, the control unit 30 controls the first driving source 15 and the sixth driving source 84 to rotate the core 14 around its axis while unwinding the flat sheet 120 toward the core 14 (step S20). As the flat sheet 120 is wound onto the core 14, the corrugated sheet 130 supplied from the corrugated sheet roll follows. Therefore, as shown in FIG. 4, a wound body 110 is formed in which the flat sheet 120 and the corrugated sheet 130 overlap each other. Here, the lengths of the flat sheet 120 and the corrugated sheet 130 in one wound body 110 are approximately constant. Therefore, when the required amount of flat sheet 120 for the wound body 110 has been supplied, the supply of the corrugated sheet 130 has finished before or at approximately the same time. Then, when the control unit 30 determines that a predetermined amount of flat plate 120 has been supplied from the flat plate roll 82, for example, it controls the first driving source 15 and the sixth driving source 84 to stop the rotation of the winding core 14 and the rotation of the flat plate roll 82. As a result, a substantially cylindrical metal base material (wound body) 110 (see FIG. 1) is formed. Note that after the rotation of the winding core 14 is stopped, the winding core 14 does not rotate around its axis but remains stopped in that position, and the shape of the wound body 110 does not change.

[0066] After this operation, the corrugated sheet roll in the corrugated sheet supply unit 28 is replaced (step S21). This corrugated sheet roll replacement work is also preferably performed automatically by an appropriate device controlled by the control unit 30. The timing for replacing the corrugated sheet roll does not have to be the timing in step S21, and any appropriate timing is allowed.

[0067] 5, the control unit 30 controls the third driving source 44 of the adjustment unit 20 to move the pad 46 in the −Z-axis direction and press the sliding surface 42a with the pad 46 (step S30). At this time, the pad 46 presses the center of the flat plate 120 in the width direction, for example.

[0068] After the rotation of the winding core 14 stops, the shape of the wound body 110 does not change, but the flat plate roll 82 can unwind the flat plate 120. When the flat plate (foil material) 120 is sandwiched between the pad 46 and the sliding surface 42a of the adjustment unit 20, the flat plate (foil material) 120 slides between the pad 46 and the sliding surface 42a. Therefore, if the flat plate 120 is pulled from the wound body 110 side (the +X axis direction side), the flat plate 120 can move in the +X axis direction through the gap between the pad 46 and the sliding surface 42a. In this way, after winding of the wound body 110 is completed, the control unit 30 controls the adjustment unit 20 to hold the flat plate (foil material) 120 so that the adjustment unit 20 can supply the flat plate (foil material) 120 toward the guide 64. In other words, the adjustment unit 20 can adjust the amount of flat plate (foil material) 120 supplied downstream in the +X axis direction toward the winding core 14. When tension is applied to the flat plate (foil material) 120, the supply amount of the flat plate (foil material) 120 may be adjusted by adjusting the thrust of the drive source 44, and the tension applied to the flat plate (foil material) 120 may be adjusted.

[0069] 6, the control unit 30 controls the fourth driving source 54 of the base unit 22 to move the guide surface 62a and the guide 64 of the plate-like member 62 in the −Z-axis direction (step S40). The amount of movement at this time is set to be equal to, for example, the assumed radius r of the wound body 110. Then, the flat plate 120 is aligned with a tangent to the wound body 110 in the −Z-axis direction.

[0070] In this way, the control unit 30 controls the fourth driving source (actuator) 54 to move the guide surface 62a in the −Z-axis direction relative to the first position, and position the surface of the XY plane of the guide surface 62a, which is virtually extended in the downstream +X-axis direction, at a position in contact with or near the wound body 110. This position of the guide surface 62a is defined as the second position.

[0071] When the control unit 30 moves the guide surface 62a from the first position to the second position, it controls the second-first drive source 17a to move the cutter 16 and the receiving portion 16a together to a predetermined position in the Z-axis direction. The movement of the cutter 16 and the receiving portion 16a in the Z-axis direction is preferably performed simultaneously with the movement of the guide surface 62, for example. At this time, the control unit 30 moves the receiving portion 16a toward the −Z-axis direction relative to the flat plate 120. The cutter 16 is positioned in the Z-axis direction such that it can cut the flat plate 120 if it is moved in the +Y-axis direction or the −Y-axis direction. However, the cutter 16 is maintained in a position toward the −Y-axis direction or the +Y-axis direction relative to the flat plate 120 so that it does not come into contact with the flat plate 120.

[0072] Using Figure 11, the distance L0 from the adjustment unit 20 to the terminal position of the corrugated plate 130 shown in Figure 5 will be compared with the distance L1 from the adjustment unit 20 to the terminal position of the corrugated plate 130 shown in Figure 6. In Figure 11, the path of distance L0 is shown by a solid line, and the path of distance L1 is shown by a dashed line.

[0073] 11, it is assumed that the terminal position 130a of the corrugated sheet 130 is located at the outermost edge of the wound body 110 in the -Z-axis direction. The distances L0 and L1 can be rephrased as the length of the flat sheet 120 from the adjustment unit 20 through the guide 64 and the guide surface 62a to the terminal position 130a of the corrugated sheet 130. In this case, the outermost flat sheet 120 on which the corrugated sheet 130 is not overlapped extends from the terminal position 130a of the corrugated sheet 130 in the -X-axis direction.

[0074] 11 is the sum of the distance α0 from the adjustment unit 20 to the guide 64, the distance (length) β in the X-axis direction on the guide surface 62a, and the distance γ0 from the downstream end 62b of the guide surface 62a to the terminal position 130a of the corrugated sheet 130 of the wound body 110 (=α0+β+γ0). Also, the distance L1 shown in FIG. 11 is the sum of the distance α1 from the adjustment unit 20 to the guide 64, the distance (length) β in the X-axis direction on the guide surface 62a, and the distance γ1 from the downstream end 62b of the guide surface 62a to the terminal position 130a of the corrugated sheet 130 of the wound body 110 (=α1+β+γ1).

[0075] Note that the length β is constant, and the distances α0 and α1 change when the guide surface 62a and the guide 64 move between the positions shown in Fig. 5 and the positions shown in Fig. 6. Similarly, the distances γ0 and γ1 change when the guide surface 62a and the guide 64 move between the positions shown in Fig. 5 and the positions shown in Fig. 6. In this case, α0<α1 and γ0>γ1.

[0076] 5 to the second position shown in Fig. 6, and the distance between the downstream end 62b of the guide surface 62a and the wound body 110 changes from distance γ0 to distance γ1, since γ0 > γ1, the flat plate 120 between the guide 64 and the wound body 110 tends to loosen and may bend. Similarly, when the guide surface 62a and the guide 64 of the plate member 62 move from the first position shown in Fig. 5 to the second position shown in Fig. 6, and the distance between the adjustment unit 20 and the guide 64 changes from distance α0 to distance α1, since α0 < α1, tension tends to be applied to the flat plate 120 between the adjustment unit 20 and the guide 64.

[0077] The static friction force between the sliding surface 42a and the pad 46 is greater than the static friction force between the guide 64 and the flat plate 120, and the kinetic friction force between the sliding surface 42a and the pad 46 is greater than the kinetic friction force between the guide 64 and the flat plate 120. For this reason, it is easier for the flat plate 120 to move or attempt to move along the guide 64 than for the flat plate 120 to move or attempt to move between the sliding surface 42a and the pad 46.

[0078] When α1-α0>γ0-γ1, when the winding of the flat plate 120 around the winding core 14 finishes, the distance L0 when the guide surface 62a is in the first position is shorter than the distance L1 when the guide surface 62a is in the second position.

[0079] At this time, the distance between the adjustment unit 20 and the guide 64 of the flat plate 120 becomes larger than the amount of slack in the flat plate 120 between the guide 64 and the wound body 110. As a result, the flat plate 120 moves through the adjustment unit 20 by a length of (α1-α0)-(γ0-γ1) toward the +X-axis direction from the adjustment unit 20. At this time, as shown in FIG. 6, the flat plate 120 between the downstream end 62b of the guide surface 62a and the terminal position of the corrugated plate 130 is in a stretched state with an appropriate tension.

[0080] The relationship between the distances L0 and L1 will be explained in more detail below.

[0081] The angle formed between α0 and α1 shown in Fig. 11 is defined as θ1, where α1 = α0 / cos(θ1) (0 < θ1 < 90°).

[0082] θ2 denotes the angle formed between the center 112a of a circle 112 that schematically shows the wound body 110 shown in FIG. 11 and the tangent T of the flat plate 120 to the circle 112. The radius of the circle 112 is r. Furthermore, d denotes the distance between the downstream end 62b of the guide surface 62a and the center of the winding core 14. In this case, γ0 can be expressed as d sin(θ2) + Δγ (0 < θ2 < 90°). Furthermore, Δγ can be expressed as 2πr × (θ3) / 360°, where (θ3) = 90° - (θ2).

[0083] Therefore, γ0=dsin(θ2)+2πr×((90°-(θ2)) / 360°.

[0084] On the other hand, γ1=d.

[0085] Therefore, L0 can be expressed as α0+β+dsin(θ2)+2πr×((90°-(θ2)) / 360°, and L1 can be expressed as α0 / cos(θ1)+β+d.

[0086] When the distance L0 is smaller than the distance L1, the rotational position of the wound body 110 does not change, and the flat plate 120 is pulled from the flat plate roll 82. At this time, as shown in Fig. 6, the flat plate 120 between the downstream end 62b of the guide surface 62a and the terminal position of the corrugated plate 130 is stretched with an appropriate tension.

[0087] Then, the control unit 30 controls the fifth driving source 72 to extend the rod portion 72b relative to the cylinder portion 72a, and the pad 74 provided on the −Z axis direction side of the rod portion 72b presses the guide surface 62a (step S50).

[0088] At this time, the pad 74 of the plate presser 24 is provided on the guide surface 62a at a position close to the downstream end 62b along the +X-axis direction and on the +Z-axis direction side of the guide surface 62a. In this case, the plate 120 can be prevented from moving within a narrower region between the position of the pad 74 closest to the +X-axis direction and the wound body 110. For this reason, the plate 120 is kept under an appropriate tension.

[0089] The control unit 30 controls the second-second drive source 17b to move the cutter 16 in the Y-axis direction while maintaining the position of the receiving portion 16a (step S60). At this time, as shown in FIG. 8, the Y-axis direction, which is the movement direction of the cutter 16, and the X-axis direction, which is the extension direction of the flat plate 120, are perpendicular to each other. This makes it easier to cut the flat plate 120 using a cutter 16 having, for example, a round blade. Therefore, when cutting the flat plate (foil material) 120, the control unit 30 controls the cutter 16 while tension is applied to the flat plate (foil material) 120 between the guide 64 and the roll 110, causing the cutter 16 to cut the flat plate (foil material) 120. The cutter 16 may move one way in the Y-axis direction to cut the flat plate 120, or may move back and forth to return to a predetermined position. After the cutter 16 moves one way in the Y-axis direction to cut the flat plate 120, the cutter 16 is positioned so as not to interfere with the subsequent flat plate 120 and corrugated plate 130 being guided toward the winding core 14. The cutter 16 and the receiving portion 16a may be provided as a pair of units so as to be movable together in the Y-axis direction. In addition, in this embodiment, the cutter 16 is positioned above the flat plate 120 on the winding core side of the wound body 110, and the receiving portion 16a is positioned below the flat plate 120. However, the cutter 16 may also be positioned below the flat plate 120, and the receiving portion 16a may also be positioned above the flat plate 120 on the winding core side of the wound body 110. Generally, the cutter 16 is larger than the receiving portion 16a. Therefore, by positioning the cutter 16 below the foil material, interference with the wound body 110 is reduced, and the flat plate 120 can be cut at a position close to the wound body 110.

[0090] When the cutter 16 is a so-called guillotine cutter, the cutter 16 has a blade extending in the Y-axis direction, and is moved in the Z-axis direction to cause the cutter 16 to cut the flat plate (foil material) 120.

[0091] Thereafter, the control unit 30 controls the transport unit 32 to transport the wound body 110, for example, to a predetermined position (step S70). The transport unit 32 may be, for example, a hand robot. At this time, the control unit 30 controls the third drive source 44 and the fifth drive source 72 to move the pad 46 away from the sliding surface 42a of the fixed portion 42 in the +Z-axis direction and the pad (pressing member) 74 away from the guide surface 62a of the plate-like member 62 of the base 52 in the +Z-axis direction. The control unit 30 also controls the fourth drive source 54 to move the plate-like member 62 of the base 52 and the guide 64 from the second position (see FIGS. 6-8) to the first position (see FIGS. 3-5). The control unit 30 also controls the second-first drive source 17a to move the cutter 16 and the receiving portion 16a in the Z-axis direction and, if necessary, in the X-axis direction. The cutter 16 and the receiving portion 16a are preferably moved in the Z-axis direction at the same time as the plate-like member 62 and the guide 64. For this reason, the manufacturing apparatus 10 for the wound body 110 is arranged as shown in FIG.

[0092] As described above, after step S21 of replacing the corrugated sheet roll in the corrugated sheet supply unit 28 is completed, the control unit 30 determines whether the corrugated sheet roll has been replaced (step S22). If the corrugated sheet roll has been replaced (step S22-Yes), the control unit 30 determines whether the flat sheet 120 remains on the flat sheet roll 82 (step S80). If the flat sheet 120 remains on the flat sheet roll 82 (step S80-Yes), the process returns to step S10. If the flat sheet 120 does not remain on the flat sheet roll 82 (step S80-No), the control unit 30 ends the manufacturing process of the wound body 110. If the corrugated sheet roll has not been replaced (step S22-No), the control unit 30 ends the manufacturing process of the wound body 110.

[0093] Furthermore, even if step S22-No is processed earlier in time than step S70 of transporting the wound body 110, the control unit 30 transports the wound body 110 that has been completely wound to, for example, a predetermined position without terminating the manufacturing process of the wound body 110 midway.

[0094] The manufacturing apparatus 10 for the wound body 110 repeats the manufacturing of the wound body 110 in this manner, and obtains a large number of wound bodies 110.

[0095] Therefore, the control unit 30 controls the fourth drive source (actuator) 54 to place the guide surface 62a at a first position where a surface obtained by virtually extending the XY plane of the guide surface 62a in the +X-axis direction on the downstream side is maintained in a state where it intersects with the winding core 14, from the start to the end of winding the flat plate (foil material) 120 around the winding core 14. Next, after the winding of the wound body 110 is completed, the control unit 30 controls the adjustment unit 20 to press the flat plate (foil material) 120 with the adjustment unit 20 so that the flat plate (foil material) 120 can be supplied toward the guide 64, and then controls the fourth drive source (actuator) 54 to move the guide surface 62a in the −Z-axis direction to a second position where a surface obtained by virtually extending the XY plane of the guide surface 62a in the +X-axis direction on the downstream side contacts the wound body 110, thereby applying tension to the flat plate (foil material) 120. Then, the control unit controls the cutter 16 while tension is being applied to the flat plate (foil material) 120, and causes the cutter 16 to cut the flat plate (foil material) 120 between the guide 64 and the wound body 110.

[0096] The pad 74 of the plate presser 24 is provided on the guide surface 62a at a position closest to the downstream end 62b in the +X-axis direction and on the +Z-axis direction side of the guide surface 62a. In this case, the plate 120 can be prevented from moving within a narrower area between the position of the pad 74 of the plate presser 24 closest to the +X-axis direction and the wound body 110. The cutter 16 is provided in the +X-axis direction downstream of the area where the pad (presser member) 74 presses the plate (foil material) 120 against the guide surface 62a. Therefore, the plate 120 can be stretched appropriately and then easily cut along the Y-axis direction using the cutter 16.

[0097] In this case, when a round blade movable in the Y-axis direction is used as the cutter 16, the Y-axis direction, which is the movement direction of the cutter 16, is perpendicular to the X-axis direction, which is the extension direction of the flat plate 120. Therefore, the flat plate 120 can be cut more easily by the cutter 16 having a blade that moves in the Y-axis direction.

[0098] At this time, when a so-called guillotine cutter having a blade extending in the Y-axis direction is used as the cutter 16, the Z-axis direction in which the cutter 16 moves and the X-axis direction in which the flat plate 120 extends are perpendicular to each other.

[0099] When the adjustment unit 20 presses the center of the flat plate 120 in the width direction and pulls the flat plate 120, the center side of the flat plate 120 in the width direction is pulled the most, and tension is less likely to be applied to the end face sides of the flat plate 120 in the width direction. If the flat plate 120 is cut with the cutter 16 in this state, the end face of the flat plate 120 may warp into an approximately C-shape or a partial arc shape. On the other hand, in this embodiment, the pad 74 of the flat plate presser 24 presses the entire flat plate 120 in the width direction against the guide surface 62a. Therefore, when the flat plate 120 is cut with the cutter 16, it is possible to prevent the end face of the flat plate 120 from warping into an approximately C-shape or a partial arc shape.

[0100] As mentioned above, the adjustment unit 20 may press the entire flat plate 120 in the width direction.

[0101] Therefore, according to this embodiment, a manufacturing apparatus 10 for a wound body 110 can be provided in which, after the supplied foil material (e.g., a flat plate 120 and a corrugated plate 130) is wound to create the wound body 110, when the supplied foil material (flat plate 120) is cut to separate the wound body 110 from the foil material (flat plate 120), bending of the foil material (flat plate 120) is unlikely to occur and the foil material (flat plate 120) can be cut at a desired position.

[0102] In the present embodiment, an example has been described in which a flat plate 120 and a corrugated plate 130 are wound as the wound body 110. For example, the manufacturing apparatus 10 for the wound body 110 according to the present embodiment can also be used when cutting the flat plate 120 to a predetermined length or a desired length.

[0103] The adjustment unit 20 is formed of a material that has slipperiness with respect to the flat plate (foil material) 120 when pressing the flat plate (foil material) 120 and is capable of supplying the flat plate (foil material) 120 to the wound body 110. Therefore, the adjustment unit 20 adjusts the slipperiness when the flat plate 120 moves in the X-axis direction. Therefore, when the wound body 110 is not moving, the adjustment unit 20, which can adjust the supply amount of the flat plate (foil material) 120, can maintain the tension applied to the flat plate 120 at an appropriate level without applying too much tension to the flat plate 120. Note that because the adjustment unit 20 can adjust the supply amount of the flat plate (foil material) 120, further tension may be applied to the flat plate (foil material) 120 as the winding core 14 rotates.

[0104] 11, the case where α1-α0>γ0-γ1 is described. That is, when guide surface 62a is in the first position at the end of winding the flat plate (foil material) around winding core 14, the distance from adjustment unit 20, through guide 64 and guide surface 62a, to the outermost edge of wound body 110 in the -Z axis direction is shorter than the distance from adjustment unit 20, through guide 64 and guide surface 62a, to the outermost edge of wound body 110 in the -Z axis direction when guide surface 62a is in the second position.

[0105] For example, there is a possibility that α1-α0≦γ0-γ1. In this case, the flat plate 120 bends between the guide 64 and the wound body 110. Therefore, when α1-α0≦γ0-γ1, it becomes more difficult for the cutter 16 to cut the flat plate 120 than when α1-α0>γ0-γ1. Alternatively, when α1-α0≦γ0-γ1, it is necessary to rewind the flat plate roll 82 in order to stretch the flat plate 120. For this reason, it is preferable to design the manufacturing apparatus 10 for the wound body 110 so that α1-α0>γ0-γ1.

[0106] In addition, in this embodiment, an example has been described in which the pad 74 of the plate presser 24 is used to press the flat plate 120 against the guide surface 62a. If an appropriate tension is applied to the flat plate 120, it may not be necessary to press the flat plate 120 against the guide surface 62a using the pad 74 of the plate presser 24. Also, for example, the cutter 16 may cut the flat plate 120 while using the receiving portion 16a to restrict the movement of the flat plate 120 in the X-axis and Z-axis directions.

[0107] In the present embodiment, the corrugated sheet 130 supplied from the corrugated sheet supply unit 28 is superimposed on the flat sheet 120 and pulled out by the rotation of the winding core 14 to form the wound body 110. For example, the corrugated sheet roll of the corrugated sheet supply unit 28 may be actively moved using a seventh drive source controlled by the control unit 30, so that the corrugated sheet 130 is supplied so as to be superimposed on the flat sheet 120.

[0108] In the present embodiment, the movement amount of the guide surface 62a when moving it from the first position to the second position and when moving it from the second position to the first position has been described as being equal to, for example, the assumed radius r of the wound body 110. The movement amount of the guide surface 62a when moving it from the first position to the second position and when moving it from the second position to the first position does not have to be equal to the assumed radius r of the wound body 110. Such a movement amount may be greater or smaller than the assumed radius r of the wound body 110. However, the movement amount is preferably equal to or greater than ½ times the assumed radius r of the wound body 110 and is preferably equal to or smaller than 3 / 2 times.

[0109] The present invention is not limited to the above-described embodiments, and various modifications can be made in the implementation stage without departing from the spirit of the invention. Furthermore, the embodiments may be implemented in appropriate combinations, in which case the combined effects can be obtained. Furthermore, the above-described embodiments include various inventions, and various inventions can be extracted by combining selected elements from the disclosed elements. For example, if the problem can be solved and the desired effect can be obtained even if some elements are deleted from all elements shown in the embodiments, the configuration from which these elements are deleted can be extracted as an invention.
