[Modes for carrying out the invention]

[0011] Hereinafter, embodiments of the corrugated sheet manufacturing apparatus for manufacturing corrugated sheets according to the present invention will be described in detail with reference to the drawings.

[0012] The corrugated sheet manufacturing apparatus 10 is a device that manufactures corrugated sheets, or so-called corrugated sheets, by applying a corrugation process to a flat sheet. As shown in Figures 1 and 2, the corrugated sheet manufacturing apparatus 10 comprises a device body 20, a slide block 22, a pair of gears 24 and 26, a pair of support shafts 28 and 30, a handle 32, a transmission mechanism 34, and an adjustment mechanism 36. Figure 1 is a cross-sectional view of the corrugated sheet manufacturing apparatus 10 from a horizontal perspective perpendicular to the rotation axes of the gears 24 and 26, and Figure 2 is a cross-sectional view along line AA in Figure 1.

[0013] The apparatus main body 20 serves as the base of the corrugated board manufacturing apparatus 10 and is generally in a block shape. The apparatus main body 20 holds a support shaft 28 so as to be rotatable around its axis, and a gear 24 is coaxially fixed to the central portion of the support shaft 28 in the axial direction thereof. Further, above the support shaft 28 of the apparatus main body 20, a space 38 larger than the outer dimension of the slide block 22 is formed so as to extend in the axial direction of the support shaft 28. And the slide block 22 is inserted into the space 38. The inner dimension of the space 38 in the left-right direction is slightly larger than the outer dimension of the slide block 22 in the left-right direction, and the inner dimension of the space 38 in the up-down direction is larger than the outer dimension of the slide block 22 in the up-down direction by a predetermined length. For this reason, the slide block 22 slides in the up-down direction inside the space 38. That is, the apparatus main body 20 holds the slide block 22 so as to be slidable by a predetermined length in the up-down direction inside the space 38.

[0014] Further, the slide block 22 holds a support shaft 30 so as to be rotatable around its axis, and the support shaft 30 is disposed above the support shaft 28 such that the axis of the support shaft 30 and the axis of the support shaft 28 are parallel. And a gear 26 is coaxially fixed to the central portion of the support shaft 30 in the axial direction thereof, and the gear 26 meshes with the gear 24. The gear 24 and the gear 26 have the same shape. Further, a handle 32 is fixed to the end of the support shaft 30, and the support shaft 30 rotates by the rotation of the handle 32.

[0015] Further, the transmission mechanism 34 transmits the rotation of the support shaft 30 to the support shaft 28. The driving force of the handle 32 is transmitted to the support shaft 28 via the support shaft 30 and the transmission mechanism 34, causing the support shaft 28 to rotate. Specifically, the transmission mechanism 34 includes a first sub-gear 50 and two second sub-gears 52 and 54. The first sub-gear 50 is coaxially fixed to the end of the support shaft 30 opposite to the end where the handle 32 is fixed. On the other hand, the two second sub-gears 52 and 54 are coaxially fixed to the end of the support shaft 28 below the first sub-gear 50. The two second sub-gears 52 and 54 are fixed to the end of the support shaft 28 with a slight phase shift from each other. The two second sub-gears 52 and 54 have the same shape.

[0016] Specifically, as shown in FIG. 3, between two adjacent teeth 60a and 60b of the plurality of teeth 60 formed on the outer peripheral surface of the first sub-gear 50, one tooth 66a of the plurality of teeth 66 formed on the outer peripheral surface of the second sub-gear 52 is engaged, and the first sub-gear 50 and the second sub-gear 52 are meshed. And one tooth 66a of the second sub-gear 52 that has entered between the two teeth 60a and 60b of the first sub-gear 50 is in contact with one tooth 60a of the two teeth 60a and 60b of the first sub-gear 50, and the first sub-gear 50 and the second sub-gear 52 are meshed. Also, one tooth 68a of the plurality of teeth 68 of the second sub-gear 54 has entered between the two teeth 60a and 60b of the first sub-gear 50, and the first sub-gear 50 and the second sub-gear 54 are also meshed. And one tooth 68a of the second sub-gear 54 that has entered between the two teeth 60a and 60b of the first sub-gear 50 is in contact with the other tooth 60b of the two teeth 60a and 60b of the first sub-gear 50, and the first sub-gear 50 and the second sub-gear 54 are meshed.

[0017] In this way, the first sub-gear 50 and the second sub-gear 52 mesh together, and the first sub-gear 50 and the second sub-gear 54 mesh together. As the support shaft 30 rotates due to the rotation of the handle 32, the rotational force of the first sub-gear 50 is transmitted to the two second sub-gears 52 and 54, causing the two second sub-gears 52 and 54 to rotate without any play. Specifically, when the first sub-gear 50 rotates, the tooth 66a of the second sub-gear 52 contacts one of the two teeth 60a and 60b of the first sub-gear 50, and the tooth 68a of the second sub-gear 54 contacts the other tooth 60b of the first sub-gear 50. Therefore, the first sub-gear 50 and the two second sub-gears 52 and 54 rotate without any play. Therefore, the support shaft 30 that rotates the first sub-gear 50 and the support shaft 28 fixed to the two second sub-gears 52 and 54 rotate in sync. In this way, the support shaft 28 and the support shaft 30 rotate in sync, causing the gear 24 fixed to the support shaft 28 and the gear 26 fixed to the support shaft 30 to rotate while meshed.

[0018] As shown in Figure 4, when gear 24 and gear 26 are meshed, gear 24 is fixed to the support shaft 28 and gear 26 is fixed to the support shaft 30 so that the multiple teeth 70 formed on the outer surface of gear 24 and the multiple teeth 72 formed on the outer surface of gear 26 do not come into contact. Therefore, when the support shafts 28 and 30 rotate synchronously and gear 24 and gear 26 rotate while meshed, the teeth 70 of gear 24 and the teeth 72 of gear 26 do not come into contact.

[0019] Furthermore, the adjustment mechanism 36 adjusts the distance between the teeth 70 of gear 24 and the teeth 72 of gear 26, more specifically, the distance between the tooth tip 70a of gear 24 and the tooth root 72b of gear 26, and the distance between the tooth root 70b of gear 24 and the tooth tip 72a of gear 26 (hereinafter referred to as "gear distance"). As shown in Figures 1 and 2, the adjustment mechanism 36 has a spacer 76, two adjustment screws 78, and two nuts 80. The spacer 76 is plate-shaped with approximately the same dimensions as the upper surface of the slide block 22, and is disposed on the upper surface of the slide block 22 inside the space 38 of the device body 20.

[0020] Furthermore, two through holes 84 are formed from the top surface of the device body 20 to the space 38, and the inner diameter of the through holes 84 is slightly larger than the outer diameter of the adjustment screw 78. Also, two through holes 86 are formed in the spacer 76, and the inner diameter of the through holes 86 is the same as the inner diameter of the through holes 84. The two through holes 84 and the two through holes 86 are in communication with each other. In addition, two screw holes 88 are formed on the top surface of the slide block 22, and the two screw holes 88 are in communication with the two through holes 86. Each of the two adjustment screws 78 is inserted through the two through holes 84 and 86, respectively, and screwed into the two screw holes 88, respectively. Also, each of the two nuts 80 is screwed onto the two adjustment screws 78 on the top surface of the device body 20.

[0021] Therefore, in the adjustment mechanism 36, when the adjustment screw 78 is screwed into the screw hole 88, the slide block 22 slides upward inside the space 38 of the device body 20, and the upper surface of the slide block 22 comes into close contact with the spacer 76. Then, when the nut 80 is screwed toward the upper surface of the device body 20, the adjustment screw 78 is fixed in place. As a result, the distance between the gears becomes a distance corresponding to the thickness dimension of the spacer 76. Spacers with different thickness dimensions than spacer 76 are available, and the distance between the gears can be changed by replacing the spacer 76, which is positioned on the upper surface of the slide block 22, with a different spacer. Therefore, the adjustment mechanism 36 makes it possible to adjust the distance between the gears by replacing the spacer with one of a different thickness dimension.

[0022] In a corrugated sheet manufacturing apparatus 10 with this structure, a flat sheet can be inserted between a pair of gears 24 and 26, and a handle 32 can be rotated to corrugate the sheet and manufacture a corrugated sheet. In the following description, as shown in Figure 5, a film-forming stainless steel sheet 108, on which a polymer film 102 for generating fine water particles is formed on both sides of a flat stainless steel sheet 100, is subjected to corrugation by the corrugated sheet manufacturing apparatus 10. The polymer film 102 for generating fine water particles is a film that generates fine water particles (hereinafter referred to as fine water particles) with a diameter of several nanometers, and the polymer film 102 for generating fine water particles will be described below.

[0023] As shown in Figure 5, the polymer membrane 102 for generating fine water particles is formed in a sheet shape and is in close contact with both sides of the flat stainless steel plate 100. Alternatively, instead of the stainless steel plate 100, a flat plate made of any conductive material from among copper-based metal materials, carbon materials (carbon paper, graphite, etc.), conductive ceramic materials (e.g., ITO), and conductive resin materials (e.g., metal-deposited film, nano-silver coating, CNT coating, etc.) can be used. The stainless steel plate 100, or the flat plate made of another conductive material, generates heat when an electric current is passed through it.

[0024] The polymer membrane 102 for generating fine water particles is formed by dispersing particles 110 having a core-shell structure in a solvent, applying the dispersion of particles 110 to both sides of a stainless steel plate 100, and then drying it. In other words, the polymer membrane 102 for generating fine water particles is manufactured by a manufacturing method that involves a coating step of applying the dispersion of particles 110 to a conductive stainless steel plate 100, and a drying step of drying the particles 110 applied to the stainless steel plate 100 after the coating step. By this manufacturing method, as conceptually shown in Figure 5, multiple particles 110 are stacked in multiple layers in a close-packed structure with a certain degree of regularity, thereby forming a sheet shape (membrane shape). The solvent of the dispersion is, for example, water.

[0025] In the unenergized state of the stainless steel plate 100, the particles 110 transition from a released state to an adsorbed state as the temperature of the polymer film 102 for generating fine water particles decreases toward room temperature, and in the energized state of the stainless steel plate 100, the particles transition from an adsorbed state to a released state as the temperature of the polymer film 102 for generating fine water particles increases from room temperature. In this embodiment, the particle size of the particles 110 is set to approximately 1 nanometer to 500 nanometers. As a result, multiple particles 110 are densely laminated on the outer surface of the stainless steel plate 100 to form the polymer film 102 for generating fine water particles. The polymer film 102 for generating fine water particles is formed such that the thickness (film thickness) when multiple particles 110 are laminated on the outer surface of the stainless steel plate 100 is 1 to 30 μm. In this embodiment, the particles 110 are formed from PEDOT / PSS (poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonic acid)).

[0026] As shown in Figure 6, particle 110 consists of a core 112 and a shell 114. The core 112 of particle 110 forms the nucleus of the particle and is made of poly(3,4-ethylenedioxythiophene), i.e., PEDOT. The shell 114 of particle 110 is made of poly(styrenesulfonic acid), i.e., PSS, a polymer material having hydrogen-bondable sulfonic acid groups (-SO3H)114a, and covers the core 112.

[0027] In this structure, when the stainless steel plate 100 is not energized, the polymer membrane 102 for generating fine water particles stabilizes at a saturated moisture absorption rate as time passes, with the amount of water adsorbed by the shell 114 of the particles 110 increasing. On the other hand, when the stainless steel plate 100 is energized and the temperature of the particles 110 rises, the polymer membrane 102 for generating fine water particles releases the moisture adsorbed by the shell 114 of the particles 110 in the form of water particles.

[0028] In the polymer membrane 102 for generating fine water particles, which is composed of particles 110 with this core-shell structure, the adsorption speed of moisture from the air in the adsorption state and the release speed of moisture into the air in the release state are faster than those of general desiccants such as silica gel. Furthermore, in the polymer membrane 102 for generating fine water particles, which is composed of particles 110 with a core-shell structure, the size of the water particles released in the release state is distributed in a very small particle size range of approximately 1 nanometer to 40 nanometers, or more specifically, 1 nanometer to 10 nanometers.

[0029] Specifically, we will first explain the speed of water adsorption and release. The polymer membrane 102 for generating fine water particles consists of particles 110 formed from PEDOT / PSS, which are laminated on a stainless steel plate 100. In this case, the shells 114 of the particles 110 are laminated in an aligned state on the polymer membrane 102 for generating fine water particles, as shown in Figure 5. Furthermore, the PSS constituting the shells 114 of the particles 110 has many sulfonic acid groups (-SO3H) 114a, which are polar functional groups capable of hydrogen bonding, on the outer surface of the shell 114, as shown in Figure 6. Therefore, water contained in the air is adsorbed onto the sulfonic acid groups 114a that are in contact with the air by hydrogen bonding.

[0030] In this case, if the amount of moisture on the surface of the polymer membrane 102 for generating fine water particles is high and the amount of moisture inside the polymer membrane 102 for generating fine water particles is low, the shell 114 of the particle 110 will use the difference in moisture concentration as a driving force to move the adsorbed moisture from the surface of the polymer membrane 102 for generating fine water particles towards the interior of the polymer membrane 102 for generating fine water particles. Also, as shown by the thick arrows in Figure 5, nanometer-sized channels 118 (hereinafter referred to as "nanochannels 118") are formed between the stacked particles 110 inside the polymer membrane 102 for generating fine water particles. These nanochannels 118 have a large distribution of sulfonic acid groups 114a, and the moisture adsorbed on the surface of the polymer membrane 102 for generating fine water particles moves at high speed into the interior of the polymer membrane 102 by traveling along the sulfonic acid groups 114a present in the nanochannels 118. In other words, the water adsorbed on the surface of the polymer membrane 102 for generating fine water particles moves into the interior of the polymer membrane 102 through the nanochannels 118. As a result, the water adsorbed on the surface of the polymer membrane 102 moves at high speed into the interior of the polymer membrane 102 due to the difference in water concentration, allowing a large amount of water to be adsorbed from the air at a rapid rate and retained.

[0031] Furthermore, since water moves using the difference in water concentration as a driving force, when there is a large amount of water inside the polymer membrane 102 for generating fine water particles and a small amount of water on the surface of the polymer membrane 102 for generating fine water particles, that is, when the air is dry, the water held inside moves at high speed from the inside of the polymer membrane 102 to the surface of the polymer membrane 102 for generating fine water particles, by traveling along the sulfonic acid groups 114a present in the nanochannels 118, contrary to the adsorption process described above. In other words, the water held inside the polymer membrane 102 for generating fine water particles moves to the surface of the polymer membrane 102 for generating fine water particles through the nanochannels 118. As a result, the water held inside the polymer membrane 102 for generating fine water particles moves at high speed to the surface of the polymer membrane 102 for generating fine water particles due to the difference in water concentration, and the polymer membrane 102 for generating fine water particles can release a large amount of water into the air at a rapid rate. Furthermore, even when the humidity of the outside air is high, by applying electricity to the stainless steel plate 100, the temperature of the polymer membrane 102 for generating fine water particles is increased, allowing the polymer membrane 102 to release a large amount of moisture into the air at a rapid rate.

[0032] Next, we will explain why the water particles released from the polymer membrane 102 for generating fine water particles are small in size during the release state. As described above, the particles 110 having a core-shell structure are PEDOT / PSS, with PEDOT in the core 112 and PSS in the shell 114. PSS has hydrophilic sulfonic acid groups 114a, which are distributed in large numbers on the outer surface and inside the shell 114. Since the polymer membrane 102 for generating fine water particles is formed by stacking particles 110 having a core-shell structure, nanochannels 118 with a channel width of several nanometers exist between multiple adjacent particles 110, and a large number of sulfonic acid groups 114a are distributed inside the nanochannels 118.

[0033] Therefore, within the nanochannel 118, there are numerous water clusters of several nanometers that are further hydrated with water molecules bonded to the sulfonic acid group 114a.

[0034] The reason why water particles of several nanometers in size are released during dehumidification is that when the stainless steel plate 100 is energized, the temperature of the polymer membrane 102 for generating fine water particles rises, supplying thermal energy to the water particles. As a result, the mobility of the water particles in the polymer membrane 102 for generating fine water particles increases, and the water clusters present in the nanochannels 118 are ejected from the numerous ejection holes present on the surface of the polymer membrane 102 for generating fine water particles, corresponding to the nanochannels 118.

[0035] Furthermore, the reason why the water particles (moisture) released from the polymer membrane 102 for generating fine water particles have a small diameter is thought to be due to a characteristic of the process by which multiple water molecules gather to form water particles. For example, if there are substances that can act as nuclei for water particles, such as ions, immediately after water molecules are released from the nozzle, it is thought that water molecules will gather around the ions, etc., and form water particles with a relatively large diameter. However, when using the polymer membrane 102 for generating fine water particles, there is no source of substances that can act as nuclei for water particles, such as ions. Therefore, it is reasonable to think that in the polymer membrane 102 for generating fine water particles, even after the water molecules present in the nanochannels 118 are ejected from the surface of the polymer membrane 102 due to thermal energy, water molecules do not easily gather, and a relatively small diameter can be maintained.

[0036] Thus, in the polymer membrane 102 for generating fine water particles, when the stainless steel plate 100 is not energized, moisture adsorbed on the surface of the polymer membrane 102 for generating fine water particles moves into the interior of the polymer membrane 102 through the nanochannels 118. This allows the moisture adsorbed on the surface of the polymer membrane 102 for generating fine water particles to be retained inside the polymer membrane 102. On the other hand, when the stainless steel plate 100 is energized, the moisture retained inside the polymer membrane 102 for generating fine water particles moves to the surface of the polymer membrane 102 through the nanochannels 118. This allows the moisture retained inside the polymer membrane 102 for generating fine water particles to be released into the air as fine particles on the surface of the polymer membrane 102.

[0037] Thus, in the film-forming stainless steel plate 108, a polymer film 102 for generating fine water particles is formed on the outer surface of the stainless steel plate 100. When the stainless steel plate 100 is energized, moisture adsorbed on the surface of the polymer film 102 can be retained inside the polymer film 102. When the stainless steel plate 100 is energized, the moisture retained inside the polymer film 102 can be released into the air as fine particles on the surface of the polymer film 102. In other words, in the film-forming stainless steel plate 108, a highly functional polymer film 102 for generating fine water particles is formed on the outer surface of the stainless steel plate 100, resulting in a film-forming stainless steel plate 108 with high performance.

[0038] When a corrugated stainless steel sheet 108, which has a highly functional polymer film 102 for generating fine water particles formed on its outer surface, is subjected to corrugation processing using a conventional corrugated sheet manufacturing apparatus, there is a risk that the function of the polymer film 102 for generating fine water particles will deteriorate. Specifically, in a conventional corrugated sheet manufacturing apparatus, as shown in Figure 7, a pair of gears 120 and 122 mesh together, and a corrugated sheet 124 is manufactured by inserting the stainless steel sheet 108 for forming the film between the meshing pair of gears 120 and 122 and rotating the pair of gears 120 and 122. Gears 120 and 122 have the same shape, and the multiple teeth 126 formed on the outer surface of gear 120 and the multiple teeth 128 formed on the outer surface of gear 122 also have the same shape.

[0039] The shape of the teeth 126 of gear 120 and the shape of the teeth 128 of gear 122 are the same as those of the corrugated plate 124. More specifically, the corrugated plate 124 has multiple peaks 130 formed at equal pitches. These multiple peaks 130 are the ends of the wavy corrugated plate 124 in the vertical direction, and are the tips of the parts that protrude in the vertical direction. The formation pitch between the multiple tooth tips 126a and tooth roots 126b of gear 120 and the formation pitch between the tooth tips 128a and tooth roots 128b of gear 122 are the same as the formation pitch of the multiple peaks 130 of the corrugated plate 124. Furthermore, the distance between the tip circle 126a1 of the tooth tip 126a of gear 120 and the root circle 126b1 of the tooth root 126b of gear 120 is the same as the height dimension of each of the multiple peaks 130, and the distance between the tip circle 128a1 of the tooth tip 128a of gear 122 and the root circle 128b1 of the tooth root 128b of gear 122 is the same as the height dimension of each of the multiple peaks 130. In addition, the shape of the tooth surface 126c between the tooth tip 126a and the tooth root 126b of gear 120 and the tooth surface 128c between the tooth tip 128a and the tooth root 128b of gear 122 is a straight shape, and is the same as the shape of the connecting portion 132 formed between two adjacent peaks 130 of the corrugated plate 124.

[0040] When the film-forming stainless steel plate 108 is corrugated by the teeth 126 of gear 120 and the teeth 128 of gear 122, the tooth tips 126a of gear 120 and the tooth tips 128a of gear 122 come into contact with the film-forming stainless steel plate 108, forming peaks 130. As gears 120 and 122 rotate, the corrugated plate 124 with the peaks 130 formed on it is transported in the direction of rotation of gears 120 and 122. At this time, the peaks 130 of the corrugated plate 124 come into contact with the tooth roots 126b of gear 120 and the tooth roots 128b of gear 122, and the connecting portion 132 of the corrugated plate 124 comes into contact with the tooth surfaces 126c of gear 120 and the tooth surfaces 128c of gear 122. In other words, when gears 120 and 122 are rotating, the tooth tips 126a of gear 120 and 128a of gear 122 contact the peaks 130 of the corrugated plate 124, the tooth roots 126b of gear 120 and 128b of gear 122 contact the peaks 130 of the corrugated plate 124, and the tooth surfaces 126c of gear 120 and 128c of gear 122 contact the connecting portion 132 of the corrugated plate 124.

[0041] Therefore, as shown in Figure 8, multiple scratches 140 are formed on the corrugated plate 124 in a direction that intersects the rotation direction of the gears 120 and 122, that is, the longitudinal direction of the crests 130, and multiple scratches 142 are also formed on the connecting portion 132. When multiple scratches 140 and 142 are formed on the crests 130 and connecting portion 132 of the corrugated plate 124 in this way, the polymer film 102 for generating fine water particles, which is formed on the outer surface of the stainless steel plate 100, is worn away, and the function of the polymer film 102 for generating fine water particles deteriorates.

[0042] In light of the above, the pair of gears 24 and 26 of the corrugated sheet manufacturing apparatus 10 have multiple teeth 70 and 72 formed on them, as shown in Figure 9. A film-forming stainless steel sheet 108 is inserted between the pair of gears 24 and 26, and the pair of gears 24 and 26 are rotated to manufacture a corrugated sheet 150. The film-forming stainless steel sheet 108 is generally in the shape of a strip, and the film-forming stainless steel sheet 108 is inserted between the pair of gears 24 and 26 in a position extending in the longitudinal direction, and the pair of gears 24 and 26 are rotated to manufacture a corrugated sheet 150 in which multiple peaks 152 extending in a direction intersecting the longitudinal direction are formed at equal pitches.

[0043] More specifically, the formation pitch between the tooth tip 70a and tooth root 70b of gear 24 and the formation pitch between the tooth tip 72a and tooth root 72b of gear 26 are the same as the formation pitch of the multiple peaks 152 of the corrugated plate 150. Also, the distance between the tooth tip circle 70a1 of the tooth tip 70a of gear 24 and the tooth root circle 70b1 of the tooth root 70b of gear 24 is the same as the height dimension of each of the multiple peaks 152, and the distance between the tooth tip circle 72a1 of the tooth tip 72a of gear 26 and the tooth root circle 72b1 of the tooth root 72b of gear 26 is the same as the height dimension of each of the multiple peaks 152. Furthermore, the shape of the tooth surface 70c between the tooth tip 70a and tooth root 70b of gear 24 and the tooth surface 72c between the tooth tip 72a and tooth root 72b of gear 26 are curved inward toward the teeth 70 and 72, and are curved inward toward the teeth 70 and 72 more than the shape of the connecting portion 154 formed between two adjacent peaks 152 of the corrugated plate 150.

[0044] When the film-forming stainless steel plate 108 is corrugated by the teeth 70 of gear 24 and the teeth 72 of gear 26, the tooth tips 70a of gear 24 and the tooth tips 72a of gear 26 come into contact with the film-forming stainless steel plate 108, forming the peaks 152. As gears 24 and 26 rotate, the corrugated plate 150 with the peaks 152 formed on it is transported in the direction of rotation of gears 24 and 26. At this time, the peaks 152 of the corrugated plate 150 come into contact with the tooth roots 70b of gear 24 and the tooth roots 72b of gear 26, but the connecting portion 154 of the corrugated plate 150 does not come into contact with the tooth surfaces 70c of gear 24 and the tooth surfaces 72c of gear 26. In other words, when gears 24 and 26 are rotating, the tooth tips 70a of gear 24 and 72a of gear 26 contact the peaks 152 of the corrugated plate 150, and the tooth roots 70b of gear 24 and 72b of gear 26 contact the peaks 156 of the corrugated plate 150. However, the tooth surfaces 70c of gear 24 and 72c of gear 26 do not contact the connecting portion 154 of the corrugated plate 150. Therefore, the tooth surfaces 70c of gear 24 and 72c of gear 26 function as non-contact areas that do not come into contact with the connecting portion 154 of the corrugated plate 150.

[0045] Therefore, as shown in Figure 10, multiple scratches 160 are formed on the corrugated plate 150 in a direction that intersects the rotation direction of the gears 24 and 26, that is, the longitudinal direction of the crests 152, but no scratches are formed on the connecting portion 154. In this way, multiple scratches 160 are formed on the crests 152 of the corrugated plate 150, but no scratches are formed on the connecting portion 154, thereby suppressing the abrasion of the polymer film 102 for generating fine water particles formed on the outer surface of the stainless steel plate 100 and preventing a deterioration of the function of the polymer film 102 for generating fine water particles.

[0046] Furthermore, in the corrugated sheet manufacturing apparatus 10, as described above, when the support shaft 30 rotates due to the rotation of the handle 32, the rotation of the support shaft 30 is transmitted to the support shaft 28 via the transmission mechanism 34, and the support shaft 28 and the support shaft 30 rotate in sync. Also, when the support shaft 28 and the support shaft 30 rotate in sync and the gears 24 and 26 rotate while meshed, the teeth 70 of the gear 24 and the teeth 72 of the gear 26 do not come into contact, as shown in Figure 4. In other words, the gears 24 and 26 rotate independently of each other without ever coming into contact.

[0047] On the other hand, in a corrugated sheet manufacturing apparatus without a transmission mechanism 34, for example, when the support shaft 30 rotates due to the rotation of the handle 32, the gear 26 fixed to the support shaft 30 rotates in the direction of arrow 170, as shown in Figure 11. At this time, the teeth 72 of gear 26 come into contact with the teeth 70 of gear 24, pushing the teeth 70 of gear 24, causing gear 24 to rotate in the direction of arrow 172. In other words, in a corrugated sheet manufacturing apparatus without a transmission mechanism 34, when gear 26 rotates due to the rotation of the handle 32, gear 24 rotates in accordance with gear 26. When corrugation is performed using a corrugated sheet manufacturing apparatus in which gear 24 rotates in accordance with gear 26 in this way, the peaks 182 of the corrugated sheet 180 do not become symmetrical, but rather have a shape that is biased in the direction of rotation of gears 24 and 26, as shown in Figure 12.

[0048] On the other hand, the corrugated sheet manufacturing apparatus 10 is equipped with a transmission mechanism 34, and gears 24 and 26 rotate independently of each other without being driven by each other. Furthermore, when gears 24 and 26 rotate while meshed, the teeth 70 of gear 24 and the teeth 72 of gear 26 do not come into contact. As a result, when corrugation is performed by the corrugated sheet manufacturing apparatus 10, the peaks 152 of the corrugated sheet 150 become symmetrical, as shown in Figure 13. This makes it possible to manufacture corrugated sheets 150 with an appropriate shape.

[0049] Furthermore, the corrugated plate 150 with the shape shown in Figure 13 also has high performance in absorbing moisture from the air and releasing the absorbed moisture into the air as fine particles. However, to achieve even higher performance, the corrugated plate 150 is wound up to manufacture a cylindrical cartridge (see Figure 15) 200. Specifically, as shown in Figure 14, an insulating film 202 is attached to one side of the corrugated plate 150, integrating the corrugated plate 150 and the insulating film 202. This causes the tip of the ridge 152 on one side of the corrugated plate 150 to be in close contact with the insulating film 202. In addition, an electrode 206 is provided on one end of the corrugated plate 150 and the insulating film 202 attached to the corrugated plate 150. This fixes the corrugated plate 150 and the insulating film 202 at one end. The corrugated sheet 150 is in the shape of a strip, and the insulating film 202 is also in the shape of a strip with approximately the same dimensions as the corrugated sheet 150.

[0050] Next, as shown in Figure 15, the integrated corrugated plate 150 and insulating film 202 are wound around the shaft 208 in multiple layers. At this time, the integrated corrugated plate 150 and insulating film 202 are wound so that the corrugated plate 150 is on the outside and the insulating film 202 is on the inside. Subsequently, one end 210a of the stainless steel plate 210 is fixed to the end of the outermost layer of corrugated plate 150 by welding. Then, the stainless steel plate 210 is wound so that it covers the outermost layer of corrugated plate 150, and the other end 210b of the stainless steel plate 210 is fixed to the outer surface of the stainless steel plate 210 by welding. This prevents the wound corrugated plate 150 and insulating film 202 from loosening. In this way, a cylindrical cartridge 200 is manufactured by winding and fixing the outermost layer of the wound corrugated plate 150 and insulating film 202 with the stainless steel plate 210. Furthermore, the polymer film 102 for generating fine water particles is not formed on the stainless steel plate 210.

[0051] In the cartridge 200 manufactured in this manner, when power is supplied to the electrodes 206 and the stainless steel plate 210, the film-forming stainless steel plate 108 of the corrugated plate 150 becomes energized, and when the power supply to the electrodes 206 and the stainless steel plate 210 is stopped, the film-forming stainless steel plate 108 of the corrugated plate 150 becomes de-energized. Therefore, by stopping the power supply to the electrodes 206 and the stainless steel plate 210, the moisture adsorbed on the surface of the polymer membrane 102 for generating fine water particles is retained inside the polymer membrane 102 for generating fine water particles. On the other hand, when power is supplied to the electrodes 206 and the stainless steel plate 210, the moisture retained inside the polymer membrane 102 for generating fine water particles is released into the air as fine particles on the surface of the polymer membrane 102 for generating fine water particles. Furthermore, in the cartridge 200, the corrugated plate 150 and the insulating film 202 are wound in multiple layers, and the insulating film 202 prevents short circuits when the film-forming stainless steel plate 108 of the corrugated plate 150 is energized.

[0052] Furthermore, when the corrugated plate 150 and the insulating film 202 are attached, the tip of the peak 152 on one side of the corrugated plate 150 and the insulating film 202 come into close contact. Also, when the corrugated plate 150 and the insulating film 202 are wound so that they are laminated in multiple layers, the tip of the peak 152 on the other side of the corrugated plate 150 and the insulating film 202 come into close contact. In other words, in the cartridge 200, the peak 152 of the corrugated plate 150 where the scratches 160 are formed are in contact with the insulating film 202. As a result, by covering the areas where peeling of the polymer membrane 102 for generating fine water particles has occurred with the insulating film 202, the deterioration of the function of the polymer membrane 102 for generating fine water particles can be further suppressed. In addition, in the cartridge 200, when the strip-shaped corrugated plate 150 is wound, the corrugated plate 150, which has a large surface area, can be made compact. As a result, the cartridge 200, which has very high moisture absorption and release performance, can be made compact.

[0053] As described in detail above, the corrugated plate 150 according to this embodiment has a polymer film 102 for generating fine water particles formed on at least one surface of the stainless steel plate 100, a plurality of ridges 152 formed on the stainless steel plate 100 on which the polymer film 102 for generating fine water particles is formed, scratches 160 formed in a direction intersecting the longitudinal direction of the ridges 152, and connecting portions 154 formed between two adjacent ridges 152. Although scratches 160 are formed on the ridges 152, scratches are not formed on the connecting portions 154. This makes it possible to suppress the deterioration of the function of the polymer film 102 for generating fine water particles.

[0054] Furthermore, in the cartridge 200, an insulating film 202 is laminated onto the corrugated plate 150. This prevents short circuits from occurring when the corrugated plate 150 is deformed, for example, by winding, bending, or curving, while the film-forming stainless steel plate 108 of the corrugated plate 150 is energized.

[0055] Furthermore, the polymer membrane 102 for generating fine water particles contains a polymer membrane that absorbs and releases moisture in response to temperature changes, and the insulating film 202 is electrically insulating. The temperature of the corrugated plate 150 and the polymer membrane 102 for generating fine water particles is controlled to allow the polymer membrane 102 to absorb and release moisture. This makes it possible to realize a cartridge 200 with high moisture absorption and release performance.

[0056] Furthermore, the corrugated sheet manufacturing apparatus 10 has gears 24 and 26 that feed a strip-shaped stainless steel sheet 100 in the longitudinal direction and form ridges 152 extending in a direction intersecting the longitudinal direction, a handle 32 for rotating the gears 24 and 26, and an adjustment mechanism 36 for adjusting the distance between the gears 24 and 26. With such a corrugated sheet manufacturing apparatus 10, corrugation processing can be applied to film-forming stainless steel sheets 108 of various thicknesses by adjusting the distance between the gears. In addition, tooth surfaces 70c and 72c that do not come into contact with the stainless steel sheet 100 during the manufacturing of the corrugated sheet 150 are provided between the tooth tips 70a and 72a and tooth roots 70b and 72b of each of the gears 24 and 26. This makes it possible to manufacture corrugated sheets 150 without scratches formed on the connection portion 154, thereby suppressing the deterioration of the function of the polymer film 102 for generating fine water particles.

[0057] It should be noted that the present invention is not limited to the embodiments described above, and various improvements and modifications are possible without departing from the spirit of the invention. For example, in this embodiment, a polymer film 102 for generating fine water particles is formed on at least one surface of a stainless steel plate 100, that is, a metal flat plate, and the stainless steel plate 100 on which the polymer film 102 for generating fine water particles is formed, that is, the film-forming stainless steel plate 108, is subjected to corrugation processing. On the other hand, a polymer film 102 for generating fine water particles may be formed on at least one surface of a non-metallic flat plate, for example, a pulp flat plate, and the pulp flat plate on which the polymer film 102 for generating fine water particles is formed may be subjected to corrugation processing. Then, a metal sheet may be attached to the corrugated pulp plate, and the pulp corrugated plate and the metal flat plate may be wound around a shaft 208 to manufacture a cartridge.

[0058] Furthermore, in this embodiment, a polymer film 102 for generating fine water particles is formed on the stainless steel plate 100, but a polymer film other than the polymer film 102 for generating fine water particles that absorbs and releases moisture due to temperature changes may also be formed. Moreover, the invention is not limited to a polymer film that absorbs and releases moisture due to temperature changes, and a film with other functions may be formed on the stainless steel plate 100.

[0059] Furthermore, in this embodiment, the cartridge 200, that is, the wound corrugated plate 150, is used as the flow channel plate. However, the corrugated plate 150 before winding, that is, the corrugated plate 150 with the shape shown in Figure 14, may also be used as the flow channel plate.

[0060] Furthermore, even with a corrugated sheet manufacturing apparatus that does not have a transmission mechanism 34, a corrugated sheet 150 without scratches formed on the connection portion 154 can be manufactured by applying a corrugation process using a pair of gears 24, 26.
