Description

  The present invention relates to an apparatus for manufacturing a sheet material on which a coating film is formed, and a method for manufacturing a sheet material on which a coating film is formed.

  As an apparatus for producing a sheet material on which a coating film is formed, there is an apparatus that uses an adsorption roller that conveys the sheet material by rotating in a state in which the sheet material is adsorbed and held (see Patent Document 1). In this manufacturing equipment, an applicator that applies the coating material to the sheet material and a drying device that dries the applied coating material are arranged around the adsorption roller, and the sheet material on which the coating film is formed is detached from the adsorption roller. Let me wind it up. The adsorption roller is generally formed from a porous body.

  When the sheet material is sucked and held by the suction roller and the coating material is applied, the manufacturing apparatus cannot be established unless the coating film is dried by the winding process. Quality defects resulting from raw drying include cracks, film thickness defects (variation, unevenness, pinholes), back surface adhesion during winding, and reduced required performance. As defects occurring in the apparatus, there are concerns about adhesion of the coating liquid into the apparatus and atmospheric dispersion of semi-dry particles. That is, it takes time until the coating film dries. The drying time is determined by the circumferential length determined by the diameter of the suction roller. In order to secure the drying time, a restriction is imposed on the conveyance speed (coating speed), resulting in a decrease in productivity and a decrease in tact time. Therefore, to increase the conveyance speed (coating speed), it is necessary to increase the diameter of the suction roller.

JP2012-104405A

  In the case of forming a cylindrical porous body, the diameter of the porous body that can be formed is limited due to the size of the press and sintering furnace used. For this reason, the adsorption roller formed from a porous body has a restriction | limiting in the upper limit of a diameter dimension.

  The conveying speed of the sheet material, that is, the rotation speed of the suction roller is determined based on the drying time required for drying the applied coating material by the drying device. When the rotation speed of the suction roller is increased in order to increase productivity, it is necessary to increase the circumference of the suction roller by increasing the diameter of the suction roller in order to ensure the drying time.

  However, as described above, since the suction roller formed from the porous body has a restriction on the upper limit of the diameter dimension, the rotation speed of the suction roller cannot be unconditionally increased. As a result, increasing productivity is hindered.

  Therefore, the object of the present invention is not limited by the upper limit of the diameter dimension, even for an adsorption roller formed from a porous body, and can increase productivity through an increase in the diameter of the adsorption roller. It is providing the manufacturing apparatus of the sheet material which formed the coating film, and the manufacturing method of the sheet material which formed the coating film.

  An apparatus for producing a sheet material having a coating film according to the present invention that achieves the above object comprises: an adsorption roller that conveys the sheet material by rotating the sheet material while adsorbing and holding the sheet material; and the sheet material on the adsorption roller And a detachment mechanism that detaches the sheet material from the suction roller. The manufacturing apparatus further includes a coating unit that applies a coating material to the sheet material that is sucked and held by the suction roller, and a downstream side of the periphery of the suction roller along the conveyance direction of the sheet material from the coating unit. And a suction part that generates a negative pressure that causes the suction roller to suck and hold the sheet material. The suction roller has a rotatable frame having a chamber connected to the suction portion, and a plurality of holding members formed on a porous body and attached to the frame in a state of communicating with the chamber. Yes. And the surrounding surface of the said adsorption | suction roller is formed with the said several holding member attached to the said flame | frame.

  A method for producing a sheet material having a coating film according to the present invention that achieves the above object comprises a rotatable frame having a chamber connected to a suction part that generates a negative pressure, and a porous body formed in the chamber. The sheet material is supplied to a suction roller having a plurality of holding members attached to the frame in a communicated state and having a peripheral surface formed by the plurality of holding members. The sheet material is conveyed by rotating the suction roller in a state where the sheet material is sucked and held. A coating material is applied to the sheet material sucked and held by the suction roller by a coating unit, and is applied at a position downstream of the coating unit in the conveyance direction of the sheet material around the suction roller. The coating material is dried by a drying unit. Then, the sheet material dried with the coating material is detached from the suction roller.

  According to the sheet material manufacturing apparatus and method for forming a coating film according to the present invention, the peripheral surface of the suction roller can be formed from a plurality of porous body holding members having a size equal to or less than the radius. Thus, an adsorption roller made of a porous material having a large diameter can be easily formed. By providing a large-diameter suction roller, the circumferential distance is increased, and the coating material can be sufficiently dried. Since the conveyance speed of the sheet material can be increased, the production speed can be improved. Therefore, even with an adsorption roller formed from a porous body, a sheet with a coating film that can increase productivity through increasing the diameter of the adsorption roller without being restricted by the upper limit of the diameter dimension. An apparatus for manufacturing a material and a method for manufacturing a sheet material on which a coating film is formed can be provided.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. However, the technical scope of the present invention should be determined based on the description of the scope of claims, and is not limited to the following embodiments. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted. In addition, the dimensional ratios in the drawings are exaggerated for convenience of explanation, and may be different from the actual ratios.

  1 and 2 are a perspective view and a schematic configuration diagram illustrating a sheet material manufacturing apparatus 200 on which a coating film according to the embodiment is formed.

  With reference to FIG. 1 and FIG. 2, the manufacturing apparatus 200 of the sheet | seat material in which the coating film was formed will outline, the raw material roller 20 around which the sheet | seat material 11 before forming a coating film was wound, and a coating film formation And a product roller 30 that winds up the sheet material 11 after having been used. The manufacturing apparatus 200 further includes a suction roller 40, a supply mechanism 80, a separation mechanism 90, an application unit 100, a drying unit 110, and a suction unit 120. The adsorption roller 40 conveys the sheet material 11 by rotating in a state where the sheet material 11 is adsorbed and held. In the illustrated embodiment, the supply mechanism 80 and the release mechanism 90 apply roller members. The unwinding roller 80 as a supply mechanism contacts the suction roller 40 via the sheet material 11 and supplies the sheet material 11 to the suction roller 40. The take-up roller 90 as a detaching mechanism contacts the suction roller 40 via the sheet material 11 and causes the sheet material 11 to be detached from the suction roller 40. The application unit 100 applies the application material to the sheet material 11 that is adsorbed and held by the adsorption roller 40. The drying unit 110 is disposed at a position downstream of the application roller 100 in the conveyance direction of the sheet material 11 around the suction roller 40 and dries the applied application material. The suction unit 120 generates a negative pressure that causes the suction roller 40 to suck and hold the sheet material 11. The suction roller 40 includes a rotatable frame 50 having a chamber 51 connected to the suction unit 120, and a plurality of holding members 60 that are formed of a porous body and attached to the frame 50 in a state of communicating with the chamber 51. Have. The peripheral surface of the suction roller 40 is formed by a plurality of holding members 60 attached to the frame 50. The manufacturing apparatus 200 further includes a cooling unit 130 that cools the holding member 60 from which the sheet material 11 is detached. Hereinafter, the configuration of the manufacturing apparatus 200 will be described in detail.

  In the present embodiment, the sheet material 11 will be described by taking, for example, an electrolyte membrane of a fuel cell electrode membrane (CCM) as an example. The coating material in this case is a catalyst ink for forming the electrode catalyst layer 15 as a coating film.

  The electrolyte membrane 11 has high hydrophilicity (permeability), and has a characteristic that the electrolyte membrane 11 swells by absorbing moisture. Swelling causes non-uniform film thickness, shrinkage, wrinkles, and cracks on the coating surface.

  For application of the catalyst ink to the electrolyte membrane 11, the electrolyte membrane 11 is not swelled but is held (supported) on the apparatus-side support (for example, a roller), and the support sheet 13 is attached and wound. A manufacturing process that does not make time for the electrolyte membrane 11 to swell is required. That is, it is necessary that the adsorption roller 40 completes a series of steps of attaching the electrolyte film 11 to the adsorption roller 40, unwinding, applying the catalyst ink, drying the catalyst ink, and winding the electrolyte film 11. is there.

  FIG. 3 is a block diagram showing a control system of the manufacturing apparatus 200.

  With reference to FIG. 3, the controller 140 controls the operation of the components in the manufacturing apparatus 200. The controller 140 includes a CPU, a memory, an input / output unit, and the like. The controller 140 controls driving of the raw material roller 20, the unwinding roller 80, the suction roller 40, the winding roller 90, the product roller 30, and the like, and applies the application unit 100, the drying unit 110, the suction unit 120, and the cooling unit 130. Control the operation of each part. Various sensors are connected to the controller 140, and a signal indicating data necessary for control, for example, a signal indicating the rotational position of the suction roller 40, a signal indicating negative pressure, and the like are input.

  Referring again to FIGS. 1 and 2, the manufacturing apparatus 200 peels the support sheet 12 from the raw material sheet 10 by the unwinding roller 80. The electrolyte membrane 11 unwound from the unwinding roller 80 is sucked and supported by the suction roller 40 and is formed by applying the catalyst ink by the applying unit 100. The catalyst ink is dried by the drying unit 110, and the electrode catalyst layer 15 is formed as a coating film. The electrolyte membrane 11 after forming the electrode catalyst layer 15 is bonded to the support sheet 13 by the take-up roller 90 to become the product sheet 14. The product sheet 14 is wound around the product roller 30.

  The raw material roller 20 winds the raw material sheet 10 in which the support sheet 12 is bonded to the electrolyte membrane 11 in a roll shape. The raw material sheet 10 is wound around the raw material roller 20 with the support sheet 12 side inward.

  The unwinding roller 80 unwinds the raw material sheet 10 from the raw material roller 20. The unwinding roller 80 assists the pressing and adsorbing and supporting of the electrolyte membrane 11 against the adsorption roller 40 while peeling the support sheet 12. The support sheet take-up roller 81 takes up the support sheet 12 peeled off by the take-out roller 80. The unwinding roller 80 is an accumulation roller so as not to be affected by the rotation speed of the suction roller 40. By changing the rotation speed of the raw material roller 20 and the support sheet take-up roller 81, the tension applied to the electrolyte membrane 11 can be controlled. The material for forming the unwinding roller 80 is not particularly limited, but can be formed from an elastic member formed of, for example, resin or rubber.

  The winding roller 90 attaches the support sheet 13 to the electrolyte membrane 11 on which the electrode catalyst layer 15 is formed, and sends it out. The support sheet unwinding roller 91 supplies the support sheet 13. The supplied support sheet 13 is stuck on the electrode catalyst layer 15 by the winding roller 90. A support sheet 13 is bonded to the electrolyte membrane 11 on which the electrode catalyst layer 15 is formed to form a product sheet 14. The product sheet 14 is wound around the product roller 30. The winding roller 90 is an accumulation roller so as not to be affected by the rotation speed of the suction roller 40. By varying the rotation speed of the support sheet unwinding roller 91 and the product roller 30, the tension applied to the electrolyte membrane 11 on which the electrode catalyst layer 15 is formed can be controlled. The winding roller 90 is configured to be able to control the pressing pressure against the suction roller 40. The winding roller 90 has a built-in heater and is configured to be able to control the heating temperature. The winding roller 90 is capable of bonding the support sheet 13 to the electrolyte membrane 11 on which the electrode catalyst layer 15 is formed by applying the pressing pressure and heat, with the pressing pressure and temperature being controlled.

  The product roller 30 has a product sheet 14 in which a support sheet 13 is bonded to the electrolyte membrane 11 on which the electrode catalyst layer 15 is formed wound in a roll shape. The product sheet 14 is wound around the product roller 30 with the support sheet 13 side inward.

  The type of the application unit 100 is not particularly limited, and for example, a slit die coater, an inkjet, a spray, a gravure coater, a knife coater, or the like can be selected. As a coating method, either solid coating or intermittent coating can be employed. In the case of adopting intermittent coating, when the coating unit 100 is constituted by a slit die coater, the coating area and the non-coating area are separately coated by intermittent coating valve switching control, coating jig drive control, sub-pump discharge control, and the like. Can do. When the application unit 100 is configured by ink jet or spray, the application area and the non-application area can be separately applied by on / off control of discharge from the application jig. When the coating unit 100 is composed of a gravure coater, the gravure plate is provided with or without a mesh, and the rotation of the gravure roller is performed so that the position of the connecting portion of the suction roller 40 described later and the position of the gravure plate without mesh are aligned. The speed and the conveyance speed of the suction roller 40 are controlled.

  The type of the drying unit 110 is not particularly limited, and for example, hot air drying, slit nozzle drying, IR drying, IH drying, and the like can be selected.

  The type of the suction unit 120 is not particularly limited. For example, the suction unit 120 includes a vacuum pump and piping and valves that connect the vacuum pump to the chamber 51 in the frame 50. By sucking the air in the chamber 51 with a vacuum pump, a negative pressure is generated that causes the adsorption film 40 to be adsorbed and held by the adsorption roller 40.

  The cooling unit 130 cools the suction roller 40 heated by the drying unit 110. This is to prevent the application unit 100 from affecting the accuracy when the coating film is formed. The type of the cooling unit 130 is not particularly limited. For example, the cooling unit 130 includes an air supply device 131 including a pump or a blower that supplies cooling air, and a temperature adjustment device 132 that adjusts the temperature of the air (described later). See FIG. The holding member 60 is cooled by allowing air to pass through the holding member 60 from which the electrolyte membrane 11 is detached by the air supply device 131.

  The air is guided to the suction roller 40 using a pipe connecting the suction unit 120 and the suction roller 40. In this case, air flows from the chamber 51 through the holding member 60 to the external atmosphere.

  The air supply device 131 can cool or heat the air temperature to a desired temperature. The temperature of the air is set to a temperature at which the holding member 60 can be cooled to a temperature at which the temperature does not affect the operation of applying the coating material.

  A humidifier can be further provided in the cooling unit 130. In this case, the holding member 60 from which the electrolyte membrane 11 is detached can be cooled and the water content of the holding member 60 can be adjusted.

  4A and 4B are a perspective view showing the suction roller 40 and a partially exploded perspective view, and FIGS. 5A and 5B are perspective views showing the frame 50 and the holding member 60 of the suction roller 40. It is.

  The suction roller 40 includes a rotatable frame 50 having a chamber 51 connected to the suction unit 120, and a plurality of holding members 60 that are formed of a porous body and are attached to the frame 50 in a state of communicating with the chamber 51. Have. A peripheral surface of the suction roller 40 is formed by a plurality of holding members 60 attached to the frame 50. The suction roller 40 further includes a connecting part 70 that joins the circumferential end surfaces of the holding members 60 adjacent to each other and the frame 50.

  In the case where the holding member 60 is formed from a porous body, when the holding member 60 is formed from a single porous body having a cylindrical shape, the radial dimension of the suction roller 40 is a porous shape having a cylindrical shape. Limited to dimensions that allow the body to be manufactured. On the other hand, in the present embodiment, since the peripheral surface of the suction roller 40 is formed by the plurality of holding members 60, the diameter of the suction roller 40 is not limited to a dimension capable of manufacturing a porous body. .

  The frame 50 can be formed from a metal material such as stainless steel. From the viewpoint of suppressing the generation of foreign matters, surface treatment such as electroless Ni plating can be performed when using an iron material. The frame 50 is provided with a shaft hole 52 through which the shaft 41 serving as the rotation shaft 41 passes. The rotating shaft 41 can also be formed integrally with the frame 50. The shape, material, and the like of the shaft 41 are not particularly limited, and can be appropriately selected in relation to the specific configuration of the apparatus in which the suction roller 40 is incorporated. A portion to which the holding member 60 is attached is provided on the outer peripheral surface portion of the frame 50. Both end surfaces along the axial direction of the frame 50 are covered with guide plates 42. Thereby, the chamber 51 inside the frame 50 is sealed. Both end surfaces along the axial direction of the holding member 60 are also sealed by the guide plate 42. The guide plate 42 can be formed from a metal material such as stainless steel. From the viewpoint of suppressing the generation of foreign matters, surface treatment such as electroless Ni plating can be performed when using an iron material.

  The chamber 51 of the frame 50 in the present embodiment has a plurality of partitioned suction chambers 53, and at least one holding member 60 faces each suction chamber 53. The suction unit 120 is connected to each suction chamber 53.

  More specifically, as shown in FIG. 5A, the frame 50 has a suction groove 54 having a window shape that can communicate with the holding member 60 on the outer peripheral surface portion to which the holding member 60 is attached. In the frame 50, a guide 55 that slightly protrudes radially outward is formed between adjacent suction grooves 54. The holding member 60 is supported and fixed by the guide 55 coming into contact with the circumferential end surface 61 of the holding member 60. The chamber 51 inside the frame 50 is partitioned into a plurality of suction chambers 53 so that the respective suction grooves 54 face each other. There is no restriction on the number of suction chambers 53. In the illustrated example, the chamber 51 is divided into eight suction chambers 53.

  As shown in FIG. 5B, the holding member 60 has a circumferential end surface 61 having a trapezoidal shape when viewed in a cross section orthogonal to the rotation shaft 41 of the suction roller 40. When the holding member 60 is incorporated into the frame 50 that is a cylindrical body, since the circumferential end surface 61 of the holding member 60 has a trapezoidal shape, the incorporation into the outer peripheral surface portion of the frame 50 is facilitated. Moreover, the process which finishes the end surface of the holding member 60 in trapezoid shape is also easy.

  The surface 62 of the holding member 60 is formed in a flat surface when viewed in a cross section orthogonal to the rotation axis 41 of the suction roller 40. Since the surface 62 is a flat surface, the holding member 60 can be easily formed.

Since the holding member 60 needs to be accurate, it is not elastically deformed and is formed of a material having a certain degree of rigidity. The holding member 60 is formed from a porous body formed from, for example, foam metal, ceramic, resin, or the like. From the viewpoints of formability, processing accuracy, device handling properties, etc., porous ceramics can be suitably used. As the porous ceramic, for example, various materials such as alumina (Al ₂ O ₃ ), silicon carbide (SiC), zirconia (ZrO ₂ ), titanium carbide (TiC), or a mixed material thereof can be used.

  As the pore size and porosity as the characteristics of the porous body, appropriate dimensions and porosity can be selected according to the sheet material 11 to be sucked and held.

  For the connecting portion 70, for example, an adhesive, a thermosetting resin, a UV curable resin, or the like can be used. Since the forming material of the connection part 70 is exposed to heat in the drying process, it is formed from a material having heat resistance. The forming material of the connecting portion 70 is formed from a material having water resistance because there is a possibility that the coating material adheres in the coating process.

  When assembling the holding member 60 to the frame 50, it is necessary to stop the holding member 60 that is a porous body so that stress is not applied to the holding member 60 to cause cracking. Therefore, it is preferable that the connecting portion 70 is stopped using the above-described adhesive or the like instead of screwing or locking using a clip.

  Each of the holding members 60 is attached to the frame 50 so as to be exchangeable. When the adsorption failure of the electrolyte membrane 11 occurs due to clogging of the holding member 60 or the like, only the specific holding member 60 in which clogging or the like has occurred can be replaced with a new holding member 60.

  FIG. 6 is a cross-sectional view showing the negative pressure path 56 in the suction roller 40.

  With reference to FIG. 6, in the present embodiment in which the chamber 51 of the frame 50 is partitioned into a plurality of suction chambers 53, the negative pressure path 56 for making the suction chamber 53 negative pressure is formed in the rotating shaft 41. An axial path 57 and a radial path 58 that is opened in the outer peripheral surface of the rotating shaft 41 and communicates with the axial path 57 are included. The outer peripheral surface of the rotating shaft 41 serves as a bottom wall constituting the suction chamber 53. The axial path 57 is connected to the negative pressure path 121 of the suction unit 120 via a path in the rotary joint 59. As the rotary joint 59, for example, an RJF series manufactured by CKD Corporation or an MQR series manufactured by SMC Corporation can be used.

  An encoder 141 that detects the rotation angle of the suction roller 40 is attached to the rotation shaft 41 of the suction roller 40. The encoder 141 is connected to the controller 140, and a signal related to the detected rotation angle of the suction roller 40 is input to the controller 140.

  FIG. 7 is a schematic configuration diagram showing the negative pressure path 121 of the suction unit 120.

  Referring to FIG. 7, the negative pressure path 121 of the suction unit 120 includes an electropneumatic regulator 122 provided for each suction chamber 53, and one vacuum pump 123 to which each electropneumatic regulator 122 is connected. Have When the electropneumatic regulator 122 is provided, the number of vacuum pumps 123 may be one, and it is sufficient to continue to suck a certain amount. For this reason, compared with the case where the several vacuum pump 123 is used, working energy can be reduced. Each electropneumatic regulator 122 can arbitrarily set a suction pressure value by program control. Each electropneumatic regulator 122 is connected to the controller 140, and a control signal indicating a suction pressure value is input from the controller 140. With such a configuration, the amount of suction in each suction chamber 53 can be controlled independently, and the state in which each suction chamber 53 is sucked can be switched.

  The negative pressure path 121 of the suction unit 120 can be selectively connected to the vacuum pump 123 and the air supply device 131 of the cooling unit 130 via the switching valve 124. The controller 140 controls the operation of the switching valve 124 and automatically switches the connection destination to the vacuum pump 123 or the air supply device 131. Thereby, the suction of the electrolyte membrane 11 through the holding member 60 made of a porous body and the air supply through the holding member 60 made of a porous body can be switched. Since the cooling unit 130 includes the temperature adjusting device 132, air having a desired temperature can be supplied to the holding member 60 from hot air to cold air.

  FIG. 8 is a flowchart showing a manufacturing process of the suction roller 40 having a plurality of porous body holding members 60, and FIGS. 9A to 9E show the frame 50 with a plurality of porous body holding members 60. It is a perspective view which shows a mode that the adsorption | suction roller 40 is assembled | attached to and manufactured.

  Referring to FIG. 8, a porous body holding member 60 is prepared with various materials (step S1), mixed and granulated (step S2), and formed into a target shape of the porous body by a press. (Step S3). As the press machine, for example, cold isostatic pressing (CIP) or hot isostatic pressing (HIP) manufactured by Kobe Steel, Ltd. is used. Then, it is baked and hardened in a sintering furnace (step S4) to obtain a porous member holding member 60. As the sintering furnace, for example, an apparatus manufactured by Chugai Furnace Industry Co., Ltd. or Daido Special Steel Co., Ltd. is used.

  Referring also to FIG. 9, after forming holding member 60, porous body holding member 60 is assembled to frame 50 in a roller shape (step S <b> 5, FIGS. 9A and 9B).

  The surface 62 of the holding member 60 assembled to the frame 50 is ground by a roller grinding machine, formed into a cylindrical shape, and accuracy is obtained (step S6, FIGS. 9C and 9D). As the processing accuracy of the holding member 60, for example, the accuracy is determined so that the eccentricity is not more than a set value. The eccentricity dimension affects the variation in coating thickness. Further, the surface shape of the holding member 60 is transferred to the sheet material 11 by suction holding. Therefore, the eccentricity dimension and the surface roughness of the surface shape of the holding member 60 are determined according to the eccentricity dimension and the surface roughness required for the target sheet material 11. As the roller grinding machine, for example, KWA-D series manufactured by Toshiba Machine Co., Ltd. is used.

  The suction roller 40 is manufactured by using the frame 50 and the holding member 60 that have been accurately obtained (step S7, FIG. 9E).

  Next, the operation of this embodiment will be described.

  The overall operation of the manufacturing apparatus 200 will be outlined with reference to FIG. The manufacturing apparatus 200 peels the support sheet 12 from the raw material sheet 10 by the unwinding roller 80. The electrolyte membrane 11 unwound from the unwinding roller 80 is sucked and supported by the suction roller 40 and is formed by applying the catalyst ink by the applying unit 100. The catalyst ink is dried by the drying unit 110, and the electrode catalyst layer 15 is formed as a coating film. The electrolyte membrane 11 after forming the electrode catalyst layer 15 is bonded to the support sheet 13 by the take-up roller 90 to become the product sheet 14. The product sheet 14 is wound around the product roller 30.

  In the present embodiment, the suction roller 40 in the manufacturing apparatus 200 is attached to the frame 50 in a state of being formed of a porous body and having a chamber 51 connected to the suction unit 120 and communicating with the chamber 51. A plurality of holding members 60. The peripheral surface of the suction roller 40 is formed by a plurality of holding members 60 attached to the frame 50.

  With the configuration in which the porous body holding member 60 is assembled to the frame 50, the large-diameter adsorption roller 40 can be obtained, and a large press or a large sintering furnace is not required. Therefore, the large suction roller 40 can be manufactured easily and in any way.

  When applying and drying the catalyst ink while adsorbing and holding the electrolyte membrane 11 by the adsorption roller 40, it is necessary to support the electrolyte membrane 11 on the adsorption roller 40 until the drying step is completed. When the diameter of the porous body is limited in production, the drying time is shortened if the conveying speed is increased in order to increase productivity. For this reason, the rotation speed of the suction roller 40 cannot be unconditionally increased, and the productivity is hindered. On the other hand, in the present embodiment, since the suction roller 40 having a large diameter can be manufactured, in order to increase the conveyance speed in order to increase productivity, the suction roller 40 is made large in diameter and the circumferential length is increased. Thus, a sufficiently long drying time (drying distance) can be easily ensured. For this reason, the production speed of the electrode film for fuel cells can be increased.

  FIG. 10 is a flowchart illustrating a procedure for switching the state in which each suction chamber 53 in the suction roller 40 is sucked by the suction unit 120. FIG. 11 is an explanatory diagram for explaining an example of a control example of the suction force for sucking the suction chamber 53. In the following description, when it is necessary to distinguish the eight suction chambers 53, as shown in FIG. 11, the first suction chamber 53 (1), the second suction chamber 53 (2), and the third suction chamber Chamber 53 (3), fourth suction chamber 53 (4), fifth suction chamber 53 (5), sixth suction chamber 53 (6), seventh suction chamber 53 (7), and eighth This is referred to as a suction chamber 53 (8).

  The controller 140 controls the operation of the suction unit 120 so as to switch the state in which each suction chamber 53 is sucked by the suction unit 120.

  The controller 140 sucks the suction chamber 53 facing the holding member 60 in contact with the sheet material 11 and stops the suction of the suction chamber 53 facing the holding member 60 from which the sheet material 11 is detached. In addition, the operation of the suction unit 120 is controlled.

  The controller 140 controls the suction force while referring to a table representing the suction chamber 53 to be sucked. First, this reference table T1 will be outlined. The controller 140 detects what number of suction chambers 53 is located at the reference rotation position, and refers to the reference table T1 to identify the suction chamber 53 that must be sucked at that time. A reference table T1 referred to in one example of control is shown in Table 1 below. Note that the rotation position of the suction chamber 53 serving as a reference is the first suction chamber 53 (1) in FIG. 11 where the holding member 60 that starts to contact the sheet material 11 supplied through the unwinding roller 80 faces. Rotation position where is located.

  With reference to FIG. 10, a procedure for switching the state in which each suction chamber 53 in the suction roller 40 is sucked by the suction unit 120 will be described.

  The controller 140 detects the rotation angle of the suction roller 40 with the encoder 141, and detects the number of the suction chamber 53 at the reference rotation position (step S11). In the state shown in FIG. 11, the first suction chamber 53 (1) is located at a reference rotational position.

  The controller 140 refers to the reference table T1 and reads the suction chamber 53 that must be suctioned based on the number of the suction chamber 53 located at the reference rotation position (step S12). When the first suction chamber 53 (1) is located at the reference rotation position from the reference table T1, "1, 2, 3, 4, 5, 6" is read as the number of the suction chamber 53 to be sucked, “100%” is read as the suction force setting, and “7, 8” is read as the number of the suction chamber 53 that is not suctioned.

  The controller 140 controls the operations of the vacuum pump 123 and the electropneumatic regulator 122 based on the number of the suction chamber 53 to be sucked, the number of the suction chamber 53 not to be sucked, and the setting of the suction force (step S13). The controller 140 sets the suction pressure value of the electropneumatic regulator 122 for the first, second, third, fourth, fifth and sixth suction chambers 53 (1) (2) (3) (4) (5) (6) A suction pressure value corresponding to a suction force of 100% is set. The controller 140 sets 0 (zero) as the suction pressure value to the suction pressure value of the electropneumatic regulator 122 for the seventh and eighth suction chambers 53 (7) (8).

  Each electropneumatic regulator 122 operates based on the set suction pressure value, independently controls the suction amount of each suction chamber 53, and switches the state of sucking each suction chamber 53. As shown in FIG. 11, the electropneumatic regulator 122 for the first, second, third, fourth, fifth and sixth suction chambers 53 (1) (2) (3) (4) (5) (6) The suction chambers 53 (1), (2), (3), (4), (5), and (6) of 1, 2, 3, 4, 5, and 6 are sucked with 100% suction force. As a result, the electrolyte membrane 11 supplied from the unwinding roller 80 is moved into the first, second, third, fourth, fifth and sixth suction chambers 53 (1) (2) (3) (4) (5) (6). It is adsorbed and held on the surface 62 of the holding member 60 facing the surface. The electrolyte membrane 11 is separated from the surface 62 of the holding member 60 facing the seventh and eighth suction chambers 53 (7) and (8) by the winding roller 90. The electropneumatic regulator 122 for the seventh and eighth suction chambers 53 (7) and (8) does not suck the seventh and eighth suction chambers 53 (7) and (8).

  Until the production of the electrolyte membrane 11 including the electrode catalyst layer 15 is completed (step S14: YES), the processes of steps S11 to S13 are repeated to switch the state of sucking the respective suction chambers 53 (1) to 53 (8). .

  As shown in FIG. 11, the suction roller 40 can independently control the suction amount for each suction chamber 53 by dividing the chamber 51 into a plurality of suction chambers 53. From the suction chamber 53 that adsorbs the electrolyte membrane 11, the suction chamber 53 from which suction leaks is partitioned. Therefore, even in the manufacturing apparatus 200 that does not adsorb the electrolyte membrane 11 to the entire circumference of the adsorption roller 40, the suction chamber 53 that must adsorb the electrolyte membrane 11 adsorbs and holds the electrolyte membrane 11 without lowering the suction force. can do.

  With respect to the suction chamber 53 that does not need to hold the electrolyte membrane 11 by suction, the suction energy is wasted because suction is stopped.

  The cooling unit 130 cools the suction roller 40 heated by the drying unit 110. For the suction chamber 53 that does not need to adsorb and hold the electrolyte membrane 11, the controller 140 controls the operation of the switching valve 124 and switches the connection destination from the vacuum pump 123 to the air supply device 131. Air flows from the suction chamber 53 through the holding member 60 to the external atmosphere. The temperature adjustment device 132 sets the temperature of the air to a temperature at which the holding member 60 can be cooled to a temperature at which the temperature does not affect the operation of applying the catalyst ink. In this manner, the temperature-controlled air is supplied from the suction pipes of the suction chambers 53 so that the temperature of the porous body is increased by the drying unit 110 within a range in which the electrolyte membrane 11 is not sucked after the winding process. Flow cooling air through 60. By cooling the holding member 60, the temperature influence on the coating process can be eliminated.

  The suction roller 40 is configured to attach a plurality of holding members 60 to the frame 50, and each of the holding members 60 is attached to the frame 50 in a replaceable manner. When the adsorption failure of the porous body occurs due to the adhesion of the electrode catalyst layer 15 or the clogging of dust, it is not necessary to replace the entire adsorption roller 40. The suction roller 40 can be restored by replacing only the holding member 60 in which the suction failure has occurred and subjecting the new holding member 60 to surface roller grinding.

  FIG. 12 is an explanatory diagram for explaining another example of the control example of the suction force for sucking the suction chamber 53. In the following description, when it is necessary to distinguish the eight suction chambers 53, as shown in FIG. 12, the first suction chamber 53 (1), the second suction chamber 53 (2), and the third suction chamber Chamber 53 (3), fourth suction chamber 53 (4), fifth suction chamber 53 (5), sixth suction chamber 53 (6), seventh suction chamber 53 (7), and eighth This is referred to as a suction chamber 53 (8).

  The controller 140 is configured to hold the suction force that sucks the suction chamber 53 facing the holding member 60 where the sheet material 11 supplied through the unwinding roller 80 starts to contact the holding member 60 where the sheet material 11 continues to contact. The operation of the suction unit 120 is controlled so that the suction force is stronger than the suction force for sucking the suction chamber 53 facing the surface.

  The controller 140 is configured so that the holding member 60 that is kept in contact with the sheet material 11 has a suction force that sucks the suction chamber 53 facing the holding member 60 where the sheet member 11 that is separated through the winding roller 90 starts to leave. The operation of the suction unit 120 is controlled so that the suction force is weaker than the suction force for sucking the suction chamber 53 that is facing.

  The controller 140 controls the suction force while referring to a table representing the suction chamber 53 to be sucked. A reference table T2 referred to in another example of the control example is shown in Table 2 below. Note that the rotation position of the suction chamber 53 serving as a reference is the first suction chamber 53 (1) facing the holding member 60 where the sheet material 11 fed through the unwinding roller 80 starts to contact in FIG. ) Is the rotation position.

  In another example of the control example, the procedure for switching the state in which each suction chamber 53 of the suction roller 40 is sucked by the suction unit 120 is the same as the example of the control example shown in FIG.

  The controller 140 detects the rotation angle of the suction roller 40 with the encoder 141, and detects the number of the suction chamber 53 at the reference rotation position (step S11). In the state shown in FIG. 12, the first suction chamber 53 (1) is located at the reference rotational position.

  The controller 140 refers to the reference table T2 and reads the suction chamber 53 that has to be suctioned based on the number of the suction chamber 53 located at the reference rotation position (step S12). When the first suction chamber 53 (1) is located at the reference rotation position from the reference table T2, “2, 3, 4, 5” is read as the number of the suction chamber 53 to be sucked and the suction force is set. Read "Normal". “1” is read as the number of the suction chamber 53 to be sucked, and “strong”, which is set to a value stronger than “normal”, is read as the suction force setting. “6” is read as the number of the suction chamber 53 to be sucked, and “weak”, which is set to a value weaker than “normal”, is read as the suction force setting. “7, 8” is read as the number of the suction chamber 53 that is not suctioned.

  The controller 140 controls the operations of the vacuum pump 123 and the electropneumatic regulator 122 based on the number of the suction chamber 53 to be sucked, the number of the suction chamber 53 not to be sucked, and the setting of the suction force (step S13). The controller 140 uses the suction pressure value of the electropneumatic regulator 122 for the second, third, fourth, and fifth suction chambers 53 (2), (3), (4), and (5) as the suction that corresponds to the “normal” suction force. Set the pressure value. The controller 140 sets the suction pressure value corresponding to the “strong” suction force to the suction pressure value of the electropneumatic regulator 122 for the first suction chamber 53 (1). The controller 140 sets the suction pressure value corresponding to the “weak” suction force to the suction pressure value of the electropneumatic regulator 122 for the sixth suction chamber 53 (6). The controller 140 sets 0 (zero) as the suction pressure value to the suction pressure value of the electropneumatic regulator 122 for the seventh and eighth suction chambers 53 (7) (8).

  Each electropneumatic regulator 122 operates based on the set suction pressure value, independently controls the suction amount of each suction chamber 53, and switches the state of sucking each suction chamber 53. As shown in FIG. 12, the electropneumatic regulator 122 for the second, third, fourth, and fifth suction chambers 53 (2), (3), (4), and (5) includes the second, third, fourth, and fifth suction chambers. 53 (2) (3) (4) (5) is sucked by “normal” suction force. The electropneumatic regulator 122 for the first suction chamber 53 (1) sucks the first suction chamber 53 (1) with a “strong” suction force. The electropneumatic regulator 122 for the sixth suction chamber 53 (6) sucks the sixth suction chamber 53 (6) with a “weak” suction force. As a result, the electrolyte membrane 11 supplied from the unwinding roller 80 is moved into the first, second, third, fourth, fifth and sixth suction chambers 53 (1) (2) (3) (4) (5) (6). It is adsorbed and held on the surface 62 of the holding member 60 facing the surface. However, the first suction chamber 53 (1) sucks the electrolyte membrane 11 with a stronger suction force than the second, third, fourth, and fifth suction chambers 53 (2) (3) (4) (5), The sixth suction chamber 53 (6) sucks the electrolyte membrane 11 with a weaker suction force than the second, third, fourth, and fifth suction chambers 53 (2), (3), (4), and (5). The electrolyte membrane 11 is separated from the surface 62 of the holding member 60 facing the seventh and eighth suction chambers 53 (7) and (8) by the winding roller 90. The electropneumatic regulator 122 for the seventh and eighth suction chambers 53 (7) and (8) does not suck the seventh and eighth suction chambers 53 (7) and (8).

  Until the production of the electrolyte membrane 11 including the electrode catalyst layer 15 is completed (step S14: YES), the processes of steps S11 to S13 are repeated to switch the state of sucking the respective suction chambers 53 (1) to 53 (8). .

  As shown in FIG. 12, the suction roller 40 can independently control the suction amount for each suction chamber 53 by dividing the chamber 51 into a plurality of suction chambers 53 as in the example shown in FIG. it can. At the location of the unwinding roller 80, the suction force is increased for initial suction to the suction roller 40, and at the location of the winding roller 90, the suction force is reduced in order to separate from the suction roller 40. By controlling in this way, the electrolyte membrane 11 can be easily handled, and the product sheet 14 can be obtained without causing problems such as wrinkles and tearing in the electrolyte membrane 11.

  Similarly to the example shown in FIG. 11, the suction chamber 53 that does not need to adsorb and hold the electrolyte membrane 11 is stopped, so that waste of suction energy can be eliminated.

  13A and 13B show a mode in which the application unit 100 intermittently applies the application material to the sheet material 11 when there is a gap S between the adjacent holding members 60 that cannot adsorb the sheet material 11. FIG. 5 is an explanatory diagram for explaining the above and a perspective view showing a state in which a gap S is detected.

  Referring to FIG. 13A, the suction roller 40 has a connecting portion 70 between adjacent holding members 60, and there is a gap S where the sheet material 11 cannot be sucked. The location where the connecting portion 70 exists cannot suck the electrolyte membrane 11, and the electrolyte membrane 11 may swell or shrink.

  Therefore, when there is a gap S between the adjacent holding members 60 where the electrolyte membrane 11 cannot be adsorbed, the application unit 100 intermittently applies the catalyst ink to the electrolyte membrane 11 to correspond to the gap S portion. The area to be applied is defined as an uncoated area. The application unit 100 has an intermittent application mechanism that intermittently applies catalyst ink. As shown in FIG. 13B, the gap S where the electrolyte membrane 11 cannot be adsorbed can be detected by using an optical sensor 142 that detects a difference in material by a difference in intensity of reflected light. Based on the signal that detects the gap S, the application unit 100 intermittently applies the catalyst ink to the electrolyte membrane 11. By setting the part corresponding to the part of the gap S to the uncoated range, the electrolyte membrane 11 is not swollen or contracted.

  As described above, in the manufacturing apparatus 200 for the sheet material 11 having the coating film according to the present embodiment, the suction roller 40 includes the rotatable frame 50 having the chamber 51 connected to the suction unit 120. And a plurality of holding members 60 attached to the frame 50 in a state of being formed of a porous body and communicating with the chamber 51. The peripheral surface of the suction roller 40 is formed by a plurality of holding members 60 attached to the frame 50.

  Moreover, in the manufacturing method of the sheet material 11 in which the coating film according to the present embodiment is formed, the sheet material 11 is supplied to the adsorption roller 40 configured as described above, and the sheet material 11 is adsorbed while being adsorbed and held. The sheet material 11 is conveyed by rotating the roller 40. A coating material is applied to the sheet material 11 held by suction by the suction roller 40 by the coating unit 100, and is applied at a position downstream of the coating unit 100 in the conveyance direction of the sheet material 11 from the periphery of the suction roller 40. The applied coating material is dried by the drying unit 110. Then, the sheet material 11 from which the coating material has been dried is separated from the suction roller 40.

  By comprising in this way, since the surrounding surface of the adsorption | suction roller 40 can be formed from the holding member 60 of the several porous body of the magnitude | size below a radius, a large sized press machine and a sintering furnace become unnecessary. Thus, it is possible to easily form the adsorption roller 40 made of a porous material having a large diameter. By providing the large-diameter adsorption roller 40, the circumferential distance is increased, and the catalyst ink can be sufficiently dried. Since the conveyance speed of the electrolyte membrane 11 can be increased, the production speed can be improved. Therefore, even if the suction roller 40 is formed of a porous body, a coating film is formed that is not restricted by the upper limit of the diameter dimension, and that can increase productivity through increasing the diameter of the suction roller 40. The manufacturing apparatus 200 of the manufactured sheet material 11 and the manufacturing method of the sheet material 11 which formed the coating film can be provided.

  The chamber 51 of the frame 50 has a plurality of partitioned suction chambers 53, at least one holding member 60 faces each suction chamber 53, and the suction portion 120 is connected to each suction chamber 53. ing.

  With this configuration, each suction chamber 53 becomes a sealed space. Therefore, even if the suction leaks from the suction chamber 53 that does not suck the electrolyte membrane 11, the suction chamber 53 that sucks the electrolyte membrane 11. The suction power is not reduced. As a result, the electrolyte membrane 11 can be reliably conveyed.

  The manufacturing apparatus 200 includes a controller 140 that controls the operation of the suction unit 120 so as to switch the state in which each suction chamber 53 is sucked by the suction unit 120.

  With this configuration, the suction amount can be controlled independently for each suction chamber 53, and the state of suction of the suction chamber 53 can be variously changed. Since the tension applied to the electrolyte membrane 11 can be variably controlled, the electrolyte membrane 11 can be transported more reliably.

  The controller 140 sucks the suction chamber 53 facing the holding member 60 in contact with the electrolyte membrane 11 and stops the suction of the suction chamber 53 facing the holding member 60 from which the electrolyte membrane 11 is detached. In addition, the operation of the suction unit 120 is controlled.

  With this configuration, the suction is stopped in a range in which the electrolyte membrane 11 is no longer sucked by winding the electrolyte membrane 11, so that the waste of suction energy is eliminated while the electrolyte membrane 11 is reliably transported. Can do.

  The controller 140 holds the suction member 53 that keeps the electrolyte membrane 11 in contact with the suction force that sucks the suction chamber 53 facing the holding member 60 that the electrolyte membrane 11 supplied through the unwinding roller 80 starts to contact. The operation of the suction unit 120 is controlled so that the suction force is stronger than the suction force for sucking the suction chamber 53 facing the surface.

  By configuring in this way, the suction force becomes strong at the position of the unwinding roller 80, so that the initial adsorption of the electrolyte membrane 11 to the adsorption roller 40 is ensured.

  The controller 140 is configured so that the holding member 60 that is kept in contact with the electrolyte membrane 11 has a suction force that sucks the suction chamber 53 facing the holding member 60 that the electrolyte membrane 11 that is separated through the winding roller 90 starts to leave. The operation of the suction unit 120 is controlled so that the suction force is weaker than the suction force for sucking the suction chamber 53 that is facing.

  With such a configuration, the suction force is weakened at the winding roller 90, so that the electrolyte membrane 11 can be easily detached from the adsorption roller 40, and the electrolyte membrane 11 can be easily handled. The product sheet 14 can be obtained without causing problems such as wrinkles and tearing in the electrolyte membrane 11.

  The manufacturing apparatus 200 further includes a cooling unit 130 that cools the holding member 60 from which the electrolyte membrane 11 is detached.

  By configuring in this way, the holding member 60 whose temperature has been raised by the drying process can be cooled within a range in which the electrolyte membrane 11 is not sucked, and the temperature influence on the coating process can be eliminated.

  The cooling unit 130 cools the holding member 60 by allowing air to pass through the holding member 60 from which the electrolyte membrane 11 is detached.

  With this configuration, the holding member 60 can be cooled by allowing air to pass through the holding member 60 within a range in which the electrolyte membrane 11 is not sucked.

  The cooling unit 130 guides the air to the suction roller 40 using a pipe connecting the suction unit 120 and the suction roller 40.

  By configuring in this way, the piping connecting the suction unit 120 and the suction roller 40 can be shared for suction and cooling, so that the piping system can be simplified.

  The temperature of the air is a temperature at which the holding member 60 can be cooled to a temperature at which the temperature does not affect the operation of applying the coating material.

  With this configuration, the holding member 60 can be cooled by the temperature-controlled air, and the temperature influence on the coating process can be reliably eliminated.

  In the case where there is a gap S that cannot adsorb the electrolyte membrane 11 between the adjacent holding members 60, the application unit 100 intermittently applies a coating material to the electrolyte membrane 11, and sets a portion corresponding to the portion of the gap S. The uncoated area.

  The suction force of the adsorption roller 40 acts on the electrolyte membrane 11 to suppress swelling, shrinkage, wrinkling, and cracking of the electrolyte membrane 11 that occurs when the catalyst ink is applied to the electrolyte membrane 11. The electrolyte membrane 11 cannot be adsorbed in the portion S. Therefore, by configuring as described above, it is possible to avoid occurrence of problems such as swelling of the electrolyte membrane 11 in the gap S where the electrolyte membrane 11 cannot be adsorbed.

  Each of the holding members 60 is attached to the frame 50 so as to be exchangeable.

  By configuring in this way, it is possible to replace only the holding member 60 in which clogging or dirt has occurred, so that the running cost can be greatly reduced as compared with the case where the entire suction roller 40 is replaced.

  The surface 62 of the holding member 60 is formed in a flat surface when viewed in a cross section orthogonal to the rotation axis 41 of the suction roller 40.

  With this configuration, since the surface 62 is a flat surface, the holding member 60 can be easily formed.

  The electrolyte membrane 11 is the electrolyte membrane 11 for the electrode catalyst layer 15 of the fuel cell, and the coating material is catalyst ink.

  With this configuration, the productivity of the fuel cell electrode film (CCM) can be increased.

(Example of frame modification)
14 is a perspective view showing a modified example of the frame 50a, FIG. 15A is a perspective view showing another modified example of the frame 50b, and FIG. 15B is a frame 50b shown in FIG. 15A. FIGS. 16A and 16B are a perspective view showing still another modified example of the frame 50d, and a main part sectional view showing a state where the holding member 60 is assembled. .

  The frame has a rotatable structure having a chamber 51 connected to the suction part 120, and has a structure in which a plurality of holding members 60 are attached in a state of being formed of a porous body and communicating with the chamber 51. As long as it is, it can be modified to an appropriate structure.

  In the frame 50 a shown in FIG. 14, the number of suction chambers 53 inside the frame 50 a is reduced with respect to the number of suction grooves 54. That is, the chamber 51 is divided into two suction chambers 53, four suction grooves 54 are formed for one suction chamber 53, and four holding members 60 are assembled.

  A frame 50b shown in FIG. 15A is a porous body (foam metal, ceramic, resin, etc.), and the chamber 51 inside the frame 50b is a single suction chamber 53. By filling one suction chamber 53 with a porous body, the holding member 60 communicates with the holding member 60 while holding the central axis. The porous body that fills one suction chamber 53 is not limited to one, and may be divided into a plurality of pieces, and does not hinder the increase in diameter of the suction roller 40. When the frame 50b is a porous body, a guide frame 50c as shown in FIG. 15B can be used together. A porous frame 50b is fitted into the guide frame 50c. By using the guide frame 50c, the mounting position accuracy of the holding member 60 is improved. Further, by using the guide frame 50c, an auxiliary function for supporting and fixing the holding member 60 and a function for assisting the connecting portion 70 are exhibited. Further, the work of assembling the holding member 60 is simplified.

  A frame 50d shown in FIG. 16A includes a rotating shaft 41 and a plate member 50e extending radially from the rotating shaft 41 in the radial direction. The suction groove 54 is not formed in the frame 50d. As shown in FIG. 16B, the holding member 60 is fitted and assembled between the radially outer ends of the plate member 50e.

(Modification example of holding member)
17 is a perspective view showing a modified example of the holding member 60a, and FIGS. 18A and 18B are cross-sectional views showing other modified examples of the holding member 60b. FIG. 19 is a perspective view showing an example in which the number of holding members 60c per suction chamber 53 is modified.

  As long as the holding member has a structure formed of a porous body and attached to the frame 50 in a state where it is communicated with the chamber 51, the holding member can be modified to an appropriate structure.

  The holding member 60a shown in FIG. 17 has a roof tile shape when viewed in a cross section orthogonal to the rotation shaft 41 of the suction roller 40. The surface 62 of the holding member 60 a is formed in an arc surface when viewed in a cross section orthogonal to the rotation shaft 41 of the suction roller 40. Since the surface 62 is a circular arc surface, it is possible to omit grinding processing for forming a cylindrical shape after the holding member 60 is assembled to the frame 50. Since the holding member 60a has a roof tile shape, when the holding member 60a is incorporated into the frame 50 that is a cylindrical body, the incorporation into the frame 50 is easy.

  18A and 18B show a modification of the shape of the side end face of the holding member 60b. The side end face 63 facing the other adjacent holding member 60b among the side end faces of the holding member 60b has a shape that overlaps with the side end face 63 of the other holding member 60b in the radial direction.

  Side end surfaces 63 shown in FIG. 18A are formed on inclined surfaces facing each other. By combining the bases of the trapezoidal shape vertically, the side end surfaces 63 of the holding member 60 overlap in the radial direction, and the gap S can be minimized.

  A side end face 63 shown in FIG. 18B has a protruding portion 64 having a stepped shape. By combining the step-shaped projections 64 vertically, the side end surfaces of the holding member 60 overlap in the radial direction, and the gap S can be minimized.

  The porous body holding member is sintered into a trapezoidal shape (FIGS. 5B and 18A), a tile shape (FIG. 17), and a stepped shape (FIG. 18B), and these are arbitrarily combined. By using it, the width of the gap S can be minimized.

  In this way, the side end face 63 facing the other adjacent holding member 60b among the side end faces 63 of the holding member 60b is shaped to overlap the side end face 63 of the other holding member 60b in the radial direction, thereby holding the holding member 60b. The gap S between them and the connecting portion 70 filled in the gap S can be minimized.

  The holding member 60 is preferably one component in the direction of the rotation shaft 41. However, as shown in FIG. 19, the holding member 60 c may be divided into a plurality of parts (two in FIG. 19) in the circumferential direction per one suction chamber 53.

(Modification example of the negative pressure path in the suction roller 40)
20 is a cross-sectional view showing a modified example of the negative pressure path 56a in the suction roller 40, and FIG. 21 is a cross-sectional view showing another modified example of the negative pressure path 56b in the suction roller 40.

  The negative pressure path for making the inside of the suction chamber 53 negative can be modified as appropriate according to the configuration of the suction roller 40.

  Referring to FIG. 20, when the chamber 51 of the frame 50 is partitioned into a plurality of suction chambers 53, the negative pressure path 56 a that creates a negative pressure in the suction chamber 53 serves as a guide plate 42 that partitions the suction chamber 53. A negative pressure forming wiring 57 a provided so as to penetrate therethrough and an in-axis wiring 58 a in which the negative pressure forming wiring 57 a is concentrated in the rotation shaft 41 are provided. The in-axis wiring 58 a is connected to the negative pressure path 121 of the suction unit 120 through a passage in the rotary joint 59.

  Referring to FIG. 21, in the case where there is one suction chamber 53 or a porous body, the negative pressure path 56 b that creates a negative pressure in the suction chamber 53 is an axial passage 57 b formed in the rotary shaft 41. And a plurality of vent holes 58b that are opened in the outer peripheral surface of the rotating shaft 41 and communicate with the axial passage. The axial passage 57 b is connected to the negative pressure path 121 of the suction unit 120.

(Modification example of negative pressure path in suction part 120)
FIG. 22 is a schematic configuration diagram illustrating a modified example of the negative pressure path 121 a of the suction unit 120.

  The negative pressure path of the suction unit 120 can be modified to an appropriate configuration as long as the suction amount of each suction chamber 53 can be controlled independently and the state of sucking each suction chamber 53 can be switched.

  Referring to FIG. 22, the negative pressure path 121 a of the suction unit 120 includes a plurality of vacuum pumps 123 provided for each suction chamber 53. Each vacuum pump 123 is connected to the controller 140, and a control signal indicating a degree of vacuum is input from the controller 140. With such a configuration, the amount of suction in each suction chamber 53 can be controlled independently, and the state in which each suction chamber 53 is sucked can be switched.

(Other modifications)
In the above-described embodiment, the electrolyte membrane 11 is taken as an example of the sheet material, but the present invention is not limited to this case. For example, a resin sheet (PTFE, PET, etc.) or a metal film (aluminum, copper, etc.) can be applied as the sheet material 11.

  Although the example which cuts the flat surface of the holding member 60 in circular arc shape after the holding member 60 was assembled | attached to the flame | frame 50 was shown, this invention is not limited to this case. The flat surface of the holding member 60 can be used as it is, and the suction roller 40 can be polygonal.

(Other frame modifications)
23A is a perspective view showing a modified example of the frame 250, FIG. 23B is an enlarged view showing a portion surrounded by reference numeral 23B in FIG. 23A, and FIG. FIG. 23D is a cross-sectional view showing the frame 250, and FIG. 23D is an enlarged view showing a portion surrounded by reference numeral 23D in FIG. 24 is a cross-sectional view showing a negative pressure path 260 in the suction roller 40a to which the frame 250 shown in FIG. 23 is applied.

  Although the example which joins the circumferential direction end surfaces 61 of the adjacent holding member 60 by the connection part 70 was shown, this invention is not limited to this case. As shown in FIGS. 23A to 23D, the connecting portion 70 is not provided between the adjacent holding members 60, and the gap S remains. A suction port 256 for supplying a negative pressure for sucking the sheet material 11 is provided on the outer peripheral surface of the frame 250 facing the gap S (for example, the end surface on the radially outer side of the guide 255). A radial path 262 communicating with the suction port 256 is formed in the plate member 257 having a guide 255 formed at the end. As shown in FIG. 24, the negative pressure path 260 for supplying a negative pressure to the gap S has an axial path 261 formed in the rotating shaft 41 and a radial path 262 formed in the plate material 257. The axial path 261 is connected to the negative pressure path 121 of the suction unit 120. Then, by sucking the air in the gap S from the suction port 256 and the circumferential end surface 61 of the holding member 60, in addition to the suction on the holding member 60, the sheet material in the portion of the gap S where the holding member 60 does not exist 11 can be adsorbed. The sheet material 11 can be sucked and held on the surface of the suction roller 40a over the entire surface from the unwinding roller 80 to the winding roller 90. As a result, the sheet material 11 can be conveyed while being stably held.

  The suction port 256 may be elliptical or rectangular in addition to the circular shape. The illustrated suction ports 256 are relatively small and arranged in large numbers. On the other hand, a through-passage can be formed by forming a large opening and inserting, incorporating, and press-fitting a porous body therein. Moreover, it can also be set as the structure which forms a big opening and covers with a mesh or a punching plate. Note that the size of the hole of the suction port 256 is preferably set to a hole diameter such that, for example, the electrolyte membrane as the sheet material 11 is not drawn into the suction port 256.

  As described above, the frame 250 has the suction port 256 that opens in the gap S that exists between the adjacent holding members 60, and the suction port 256 is connected to the suction unit 120 to suck the sheet material 11 that covers the gap S. It has a structure that generates negative pressure.

  With this configuration, even if there is a seam (having the width of the guide 255) formed by the gap S between the adjacent holding members 60, the sheet material 11 is caused by the negative pressure supplied from the suction port 256. Therefore, the sheet material 11 being conveyed can be sucked and held over the entire surface. As a result, the sheet material 11 can be conveyed while being stably held.

  FIG. 25 is a cross-sectional view showing a modified example of the negative pressure path 260a in the suction roller 40a to which the frame 250 shown in FIG. 23 is applied.

  In this modified example, the radial path 262 communicating with the suction port 256 is aggregated at one place like a header pipe in the plate member 257 to form an aggregate path 263. The negative pressure path 260 a that supplies a negative pressure to the gap S includes an axial path 261 and an aggregation path 263 that communicates with the axial path 261. The axial direction path 261 is connected to the negative pressure path 121 of the suction unit 120 via a path in the rotary joint 59.

  FIG. 26 is a cross-sectional view showing another modified example of the negative pressure path 260b in the suction roller 40a to which the frame 250 shown in FIG. 23 is applied.

  In another modified example, the negative pressure path 260 b includes a negative pressure forming wiring 263 a provided so that the aggregation path 263 penetrates the guide plate 42 defining the suction chamber 53, and a negative pressure forming wiring 263 a in the rotating shaft 41. And the in-axis wiring 263b. The in-axis wiring 263 b is connected to the negative pressure path 121 of the suction unit 120 through a passage in the rotary joint 59.

  FIG. 27 is a schematic configuration diagram illustrating a modified example of the negative pressure path 121b of the suction unit 120.

  As described above, the negative pressure path 121 of the suction unit 120 can independently control the suction amount of each suction chamber 53 and switch the state of sucking each suction chamber 53 (see FIG. 7). Similarly, the negative pressure path 121b of the suction part 120 can independently control the suction amount of each suction chamber 53 and each gap S, and can switch the state of sucking each gap S.

  Referring to FIG. 27, the negative pressure path 121b of the suction unit 120 includes a plurality of vacuum pumps 123 provided for each suction chamber 53 and a plurality of vacuum pumps 264 provided for each gap S. Have. Each vacuum pump 123, 264 is connected to the controller 140, and a control signal indicating the degree of vacuum is input from the controller 140. With such a configuration, the suction amount of each suction chamber 53 and each gap S can be controlled independently, and the state of sucking each suction chamber 53 and each gap S can be switched.

  Since the gap S has a relatively small volume, even if the suction amount is constant, there is a case where the influence on the adsorption of the sheet material 11 is small. In such a case, a negative pressure path communicating with the suction port 256 can be gathered to form a negative pressure with a single vacuum pump.

(Further modifications of the frame)
FIG. 28A is a perspective view showing a modified example of the frame 250a and a main part of the suction roller 40b to which the frame 250a is applied, and FIG. 28B is a perspective view showing a roller structure 265 constituting the suction roller 40b. FIG. 28 (C) is a perspective view showing a divided frame 266 constituting the frame 250a, and FIG. 28 (D) is a view showing a position where the roller constituting bodies 265 are joined together. FIG. 29 is a flowchart showing a schematic procedure for assembling a plurality of roller constituting bodies 265 having the holding member 60 attached to the divided frame 266 to form the suction roller 40b.

  Although the case where the frame 50 of the suction roller 40 is formed as a single body has been shown, the present invention is not limited to this case. As shown in FIGS. 28A to 28D, one frame 250a can be formed by forming a divided frame 266 as a minimum unit and combining a plurality of divided frames 266. By using the divided frame 266, the roller constituent body 265 serving as a minimum unit is formed, and by combining a plurality of roller constituent bodies 265, one suction roller 40b can be formed. The divided frame 266 and the roller structure 265 have a fan shape when viewed in a cross section orthogonal to the rotation shaft 41 of the suction roller 40b. The roller structure 265 includes a divided frame 266 in which the suction chamber 53 and the suction groove 54 are formed, and a holding member 60 attached to the divided frame 266 so as to face the suction chamber 53. The holding member 60 is attached to the suction groove 54 using an adhesive or the like. And the some roller structure 265 is couple | bonded in the state which contacted the circumferential direction end surfaces 61 of the holding member 60 adjacent. In the illustrated example, the number of the divided frames 266 and the roller constituting bodies 265 is eight. However, the number of the divided frames 266 and the roller constituting bodies 265 is not limited to this. Can be formed.

  Referring to FIG. 29, in order to form the suction roller 40b, first, the shape processing of the divided frame 266 is performed (step S21). The suction chamber 53 and the suction groove 54 of the divided frame 266 are carried out until finishing. The size of the holding member 60 is preferably slightly larger than the size of the divided frame 266. Next, using a connecting means such as an adhesive, the holding member 60 is attached to the suction groove 54 to form a roller structure 265 that is an integral part of the divided frame 266 and the holding member 60 (step S22). Next, surface grinding is simultaneously performed on the connecting surface 266a of the divided frame 266 together with the divided frame 266 and the holding member 60 (step S23). A line segment denoted by reference numeral 267a in FIG. 28B indicates a range in which the divided frame 266 and the holding member 60 are subjected to surface grinding simultaneously. Adjacent divided frames 266 are integrated by joining the connecting surfaces 266a of the divided frames 266 with an adhesive. A line segment denoted by reference numeral 267b in FIG. 28D indicates a range where adjacent divided frames 266 are joined. Then, by repeating the joining of the divided frames 266 in the circumferential direction, the roller constituting body 265 is assembled to form the suction roller 40b (step S24).

  The frame 250a is a combination of a plurality of divided frames 266. By connecting the holding members 60 to the individual divided frames 266 in advance and setting them as one component, the roller structure 265 eliminates the need for a guide 55 (see FIG. 5) for attaching the holding members 60. Furthermore, the roller structure 265 is an integral part of the divided frame 266 and the holding member 60. By jointly processing the divided frame 266 and the holding member 60, the joint surface of the adjacent roller structure 265 can be made with high accuracy. Planar processing is possible. For this reason, it is possible to accurately match the surfaces of the holding members 60 without causing a gap. The operation | work which joins holding member 60 with an adhesive agent is also unnecessary. Thus, the sheet material 11 can be sucked and held on the surface of the suction roller 40b over the entire surface from the unwinding roller 80 to the winding roller 90. As a result, the sheet material 11 can be conveyed while being stably held.

  As described above, the frame 250 a has a plurality of divided frames 266 in which the suction chamber 53 is formed, and the suction roller 40 b has a plurality of attachment members 60 attached to the divided frame 266 so as to face the suction chamber 53. A roller structure 265 is provided. And the adsorption | suction roller 40b has the structure couple | bonded in the state which the circumferential direction end surfaces 61 of the holding member 60 where the some roller structure 265 adjoins contacted.

  By attaching the holding member 60 to the divided frame 266 and forming the roller structure 265 as a single component, the circumferential end surface 61 of the holding member 60 can be finished with high accuracy. With this configuration, there is no joint between the holding members 60 adjacent to each other, there is no place where the sheet material 11 cannot be sucked, and the conveyed sheet material 11 is sucked and held over the entire surface. Can do.

(Example of measures taken when starting sheet material adsorption)
FIG. 30A is a diagram illustrating a failure example in the process of adsorbing the sheet material 11 to the adsorption roller 40, FIG. 30B is a perspective view for explaining the curl of the sheet material, and FIG. These are sectional views which follow the 30C-30C line of Drawing 30 (B). FIG. 31 is a perspective view showing a modified example of the suction roller 40c in a state where a part of the holding member 60 is removed. FIG. 32 is a schematic configuration diagram showing the negative pressure path 121 c of the suction unit 120.

  As shown in FIG. 30A, the support sheet 12 is peeled from the raw material sheet 10 by the unwinding roller 80, and the unwound sheet material 11 is sucked and supported by the suction roller 40. In the unwinding (suction) process in which the sheet material 11 is attracted to the suction roller 40, problems such as air entrainment and mixing, and generation of wrinkles occur. The cause of such inconvenience is that the suction force of the suction roller 40 is weak with respect to the bonding force (peeling force) between the support sheet 12 and the sheet material 11, and as a result, the sheet material 11 is bent, and the suction roller. This is because a relatively large space is generated between the front surface 40 and the surface 40 (see the portion denoted by reference numeral 268a in FIG. 30A). In particular, as shown in FIGS. 30B and 30C, when the raw material sheet 10 has a curl or when the stress acts unevenly in the wound roll material state, the unrolled sheet material. 11 also tends to bend (curl 268b) at both end edges along the roller axis direction. As a result, the suction force of the suction roller 40 is lost in the portion including both end edges of the sheet material 11, and the above-described problems such as the generation of wrinkles appear remarkably.

  Referring to FIG. 31, the suction roller 40 c has a structure in which measures against problems such as wrinkles at the start of suction of the sheet material 11 are taken. The suction roller 40c has a structure in which the roller structure 265 is coupled to the circumferential direction of the rotation shaft 41 of the suction roller 40c and coupled to the cylindrical height direction, that is, the axial direction of the rotation shaft 41 of the suction roller 40c. In the roller structure 265, the holding member 60 is connected to the divided frame 266 in the same manner as the roller structure 265 shown in FIG. The plurality of roller constituting bodies 265 are coupled in a state where the circumferential end surfaces 61 of the holding members 60 adjacent in the circumferential direction are in contact with each other, and the axial end surfaces of the holding members 60 adjacent in the cylindrical height direction are brought into contact with each other. It is connected in the state. Therefore, the suction chamber 53 of the suction roller 40c is partitioned along both the circumferential direction and the axial direction of the rotation shaft of the suction roller 40c. In the illustrated example, the number of roller constituents 265 is eight in the circumferential direction and two in the cylindrical height direction. However, the present invention is not limited to this case, and the suction roller 40c is removed from an appropriate number of roller constituents 265. Can be formed.

  Referring to FIG. 32, the negative pressure path 121c of the suction unit 120 includes a plurality of units provided for each suction chamber 53 partitioned along both the circumferential direction and the axial direction of the rotation shaft 41 of the suction roller 40c. Vacuum pump 269. Each vacuum pump 269 is connected to the controller 140, and a control signal indicating a degree of vacuum is input from the controller 140. With such a configuration, the amount of suction in each suction chamber 53 can be controlled independently, and the state in which each suction chamber 53 is sucked can be switched. It is also possible to group several suction chambers 53 so that a suction mode can be realized, and to provide a vacuum pump 269 for each group, and to switch the state of sucking each suction chamber 53 for each group. In FIG. 32, the negative pressure path 121c is illustrated in a state where eight roller constituent bodies 265 are coupled in the circumferential direction and two are coupled in the cylindrical height direction.

  FIG. 33A is an explanatory diagram for explaining a control example of the suction force for sucking the suction chamber 53 along the circumferential direction of the rotation shaft 41 of the suction roller 40c, and FIG. 33B is a rotation of the suction roller 40c. FIG. 10 is an explanatory diagram for explaining a control example of suction force for sucking a suction chamber 53 along the axial direction of a shaft 41. In the following description, when distinguishing the eight suction chambers 53 along the circumferential direction of the rotating shaft, as shown in FIG. 33A, the first circumferential suction chamber 53 (v1), the second circumferential direction, Suction chamber 53 (v2), third circumferential suction chamber 53 (v3), fourth circumferential suction chamber 53 (v4), fifth circumferential suction chamber 53 (v5), sixth circumferential suction chamber 53 (v6), seventh circumferential suction chamber 53 (v7), and eighth circumferential suction chamber 53 (v8). When distinguishing the five suction chambers 53 along the axial direction of the rotation shaft, as shown in FIG. 33B, the first axial suction chamber 53 (h1) and the second axial suction chamber 53 are provided. (H2), a third axial suction chamber 53 (h3), a fourth axial suction chamber 53 (h4), and a fifth axial suction chamber 53 (h5).

  In order to peel the support sheet 12 from the raw material sheet 10 and cause the sheet material 11 to be adsorbed to the adsorption roller without causing defects such as wrinkles in the unwinding (adsorption) process, It is necessary to adsorb with a suction force stronger than a normal suction force. Moreover, since the curvature (curl 268b) of the both end edges along a roller axial direction is easy to generate | occur | produce, it is also necessary to make the suction force of the adsorption | suction roller 40 not lose.

  Therefore, the controller 140 controls the suction force for sucking the suction chamber 53 partitioned along both the circumferential direction and the axial direction of the rotation shaft 41 of the suction roller 40c as follows.

  Referring to FIG. 33A, the controller 140 relates to the suction chambers 53 facing the holding member 60 in contact with the sheet material 11 out of the suction chambers 53 partitioned along the circumferential direction of the rotation shaft 41. The suction force for sucking the suction chamber 53 is set to a stronger suction force when the sheet material 11 supplied through the unwinding roller 80 starts to contact than when the sheet material 11 continues to contact. The operation of the suction unit 120 is controlled.

  As shown in the drawing, the controller 140 uses the second to sixth circumferences in which the sheet material 11 continues to be in contact with the suction force that sucks the first circumferential suction chamber 53 (v1) where the sheet material 11 starts to contact. The operation of the suction unit 120 is controlled so that the suction force is stronger than the suction force for sucking the directional suction chambers 53 (v2) to 53 (v6). In the illustrated example, the suction force for sucking the eighth circumferential suction chamber 53 (v8) is also a strong suction force so as not to cause a delay in the suction of the sheet material 11.

  By controlling the suction force for sucking the suction chamber 53 partitioned along the circumferential direction of the rotation shaft 41 of the suction roller 40c as described above, the suction force of the sheet material 11 at the start of suction is stronger than the normal suction force. Can be adsorbed. As a result, in the unwinding (adsorption) process, the support sheet 12 is peeled from the raw material sheet 10 without causing problems such as air entrainment and mixing, and generation of wrinkles, and the sheet material 11 is adsorbed to the adsorption roller 40c. Can do.

  Referring to FIG. 33 (B), the controller 140 faces the holding member 60 that comes into contact with both edges of the sheet material 11 along the axial direction in the suction chamber 53 that is partitioned along the axial direction of the rotation shaft 41. With respect to the suction chambers 53, the suction force for sucking these suction chambers 53 is greater when the sheet material 11 supplied through the unwinding roller 80 starts to contact than when the sheet material 11 continues to contact. The operation of the suction unit 120 is controlled so as to obtain a strong suction force.

  In FIG. 33B, a plurality of suction chambers 53 are represented in 8 rows and 5 columns. The row direction indicates the eighth circumferential suction chamber 53 (v8) and the first to seventh circumferential suction chambers 53 (v1) to 53 (v7) in order from the bottom to the top. The column direction indicates the first to fifth axial suction chambers 53 (h1) to 53 (h5) in order from left to right. “Strong” and “medium” of suction force are shown in the cell. A blank cell indicates a normal suction force. A cell with “medium” has a stronger suction than the normal state, and a cell with “strong” has a stronger suction than the “medium” state.

  The first axial suction chamber 53 (h <b> 1) and the fifth axial suction chamber 53 (h <b> 5) correspond to the suction chamber 53 in which the holding member 60 with which both end edges of the sheet material 11 are facing. As shown in the figure, the controller 140 is arranged in the first circumferential suction chamber 53 (second stage from the bottom) of the first circumferential suction chamber 53 (v1) where the sheet material 11 starts to contact. h1), the suction force for sucking 53 (h5), the rows of the fourth to sixth circumferential suction chambers 53 (v4) to 53 (v6) in which the sheet material 11 is kept in contact (from the bottom 5 to 7) In the second stage), the operation of the suction unit 120 is controlled so that the suction force is stronger than the suction force for sucking the first and fifth axial suction chambers 53 (h1) and 53 (h5). In the illustrated example, the first to fifth axial suctions are performed in the row (bottom row) of the eighth circumferential suction chamber 53 (v8) in order to prevent a delay in the suction of the sheet material 11. The suction force for sucking the chambers 53 (h1) to 53 (h5) is also a strong suction force. In the row of the first circumferential suction chamber 53 (v1) (second stage from the bottom), the suction force for sucking the second to fourth axial suction chambers 53 (h1) to 53 (h5) is also strong. It is said. In the row of the second circumferential suction chamber 53 (v2) (third stage from the bottom), the suction force for sucking the first and fifth axial suction chambers 53 (h1) and 53 (h5) is strong. The suction force for sucking the second to fourth axial suction chambers 53 (h2) to 53 (h4) is stronger than the normal suction force, and the first and fifth axial suction chambers 53 are left as they are. The suction force is a moderate suction force that is weaker than the suction forces of (h1) and 53 (h5). In the row of the third circumferential suction chamber 53 (v3) (fourth stage from the bottom), the suction force for sucking the first and fifth axial suction chambers 53 (h1) and 53 (h5) is strong suction. The suction force for sucking the second and fourth axial suction chambers 53 (h2) and 53 (h4) is a moderate suction force, and the third axial suction chamber 53 (h3) is sucked. The suction force to be used is a normal suction force. In the row of the fourth circumferential suction chamber 53 (v4) (fifth stage from the bottom), the suction force for sucking the first and fifth axial suction chambers 53 (h1) and 53 (h5) is moderate. The suction force for sucking the second to fourth axial suction chambers 53 (h2) to 53 (h4) is a normal suction force. In the rows of the fifth to seventh circumferential suction chambers 53 (v5) to 53 (v7) (the sixth to eighth stages from the bottom), the first to fifth axial suction chambers 53 (h1) to 53 ( The suction force for sucking h5) is all normal suction force. The above-described control of the suction force for sucking the first to fifth axial suction chambers 53 (h1) to 53 (h5) is merely an example, and the first to the fifth suction chambers 53 (h1) to 53 (h5) The suction force of the fifth axial suction chambers 53 (h1) to 53 (h5) can be varied as appropriate.

  By controlling the suction force for sucking the suction chamber 53 partitioned along the axial direction of the rotation shaft 41 of the suction roller 40c as described above, the warp (curl 268b) occurs at the portion including both end edges of the sheet material 11. Even if it occurs, the suction force of the suction roller 40c is not lost. As a result, in the unwinding (adsorption) process, the support sheet 12 is peeled from the raw material sheet 10 without causing problems such as air entrainment and mixing, and generation of wrinkles, and the sheet material 11 is adsorbed to the adsorption roller 40c. Can do.

  Thus, the suction chamber 53 is partitioned along both the circumferential direction and the axial direction of the rotation shaft 41 of the suction roller 40c. The controller 140 includes a suction chamber 53 that faces the holding member 60 that contacts the sheet material 11 among the suction chambers 53 that are partitioned along the circumferential direction of the rotation shaft 41, and a partition along the axial direction of the rotation shaft. Among the suction chambers 53, with respect to the suction chambers 53 facing the holding members 60 that are in contact with both end edges along the axial direction of the sheet material 11, the sheet material 11 contacts the suction force for sucking these suction chambers 53. When starting, the operation of the suction unit 120 is controlled so that the suction force is stronger than when the sheet material 11 is kept in contact.

  With this configuration, the sheet material 11 that has started to be sucked can be sucked with a suction force stronger than a normal suction force, and further, a warp (curl 268b) occurs in a portion including both end edges of the sheet material 11. Even if it is, the suction force of the suction roller 40c is not lost. As a result, in the unwinding (adsorption) process, the support sheet 12 is peeled from the raw material sheet 10 without causing problems such as air entrainment and mixing, and generation of wrinkles, and the sheet material 11 is adsorbed to the adsorption roller 40c. Can do.

(Example of measures taken when sheet material is removed (1))
FIG. 34 is a diagram illustrating a failure example in the process of separating the sheet material 11 from the suction roller 40, and FIG. 35 is a schematic configuration diagram illustrating the negative pressure path 121 d and the positive pressure supply path 270 of the suction unit 120.

  As shown in FIG. 34, the support sheet 13 is attached to the sheet material 11 by the take-up roller 90 and is detached from the suction roller 40 as the product sheet 14. In the winding (detaching) step of releasing the sheet material 11 from the suction roller 40, problems such as air entrainment and mixing and generation of wrinkles occur. The cause of such inconvenience is that the suction force of the suction roller 40 is stronger than the bonding force (sticking force) between the support sheet 13 and the sheet material 11, and as a result, the sheet material 11 is bent, and the suction roller. This is because a relatively large space is generated between the surface and the surface of 40 (see the portion denoted by reference numeral 268c in FIG. 34). In the winding (detaching) step, it is difficult to control the tension applied to the sheet material 11, control the feed speed of the sheet material 11, and control to apply a uniform tension in the roll width direction of the sheet material 11. For this reason, it is difficult to adjust the position of the winding roller 90 to the optimum separation position of the sheet material 11, which also causes a problem.

  The suction roller 40c is the same as that shown in FIG. 31, and the roller constituting body 265 is coupled to the circumferential direction of the rotation shaft 41 of the suction roller 40c, and at the same time as the cylindrical height direction, that is, the rotation shaft 41 of the suction roller 40c. It has a structure coupled in the axial direction.

  Referring to FIG. 35, the negative pressure path 121d of the suction portion 120 is an electropneumatic provided for each suction chamber 53 partitioned along both the circumferential direction and the axial direction of the rotation shaft 41 of the suction roller 40c. It has a regulator 122 and one vacuum pump 123 to which each electropneumatic regulator 122 is connected. When the electropneumatic regulator 122 is provided, the number of vacuum pumps 123 may be one, and it is sufficient to continue to suck a certain amount. For this reason, compared with the case where the several vacuum pump 123 is used, working energy can be reduced. Each electropneumatic regulator 122 can arbitrarily set a suction pressure value by program control. Each electropneumatic regulator 122 is connected to the controller 140, and a control signal indicating a suction pressure value is input from the controller 140. With such a configuration, the amount of suction in each suction chamber 53 can be controlled independently, and the state in which each suction chamber 53 is sucked can be switched.

  The negative pressure path 121d of the suction unit 120 can be selectively connected to a vacuum pump 123 and a compressor 271 as a supply unit that supplies positive pressure via a switching valve 124. The type of gas supplied by the compressor 271 is not particularly limited, but air can be used. The controller 140 controls the operation of the compressor 271 so as to switch the situation in which the compressor 271 supplies a positive pressure to each suction chamber 53. That is, the controller 140 controls the operation of the switching valve 124 and automatically switches the connection destination to the vacuum pump 123 or the compressor 271. Thereby, the suction of the suction chamber 53 and the supply of the positive pressure to the suction chamber 53 can be switched. 35 shows the negative pressure path 121d and the positive pressure supply path 270 of the suction part 120 only for the suction chamber 53 partitioned along the circumferential direction. The suction roller 40c is also coupled with a roller structure 265 in the cylindrical height direction. Although not shown, a similar negative pressure path 121d and positive pressure supply path 270 are also provided in the cylinder height direction. As a result, a positive pressure can be applied to the sheet material 11 at an arbitrary location by an arbitrary air volume.

  36A is an explanatory diagram for explaining a control example for supplying a positive pressure to the suction chamber 53 along the circumferential direction of the rotation shaft 41 of the suction roller 40c, and FIG. 36B is a rotation of the suction roller 40c. It is explanatory drawing for demonstrating the example of control which supplies a positive pressure to the suction chamber 53 along the axial direction of the axis | shaft 41. FIG.

  In order to attach the support sheet 13 to the sheet material 11 and remove it from the suction roller 40c without causing defects such as wrinkles in the winding (detaching) step, the support sheet 13 and the sheet material 11 at the time of separation are used. It is necessary to make the suction force of the suction roller 40c weaker than the joining force (sticking force).

  Therefore, the controller 140 supplies the positive pressure to the suction chamber 53 partitioned along both the circumferential direction and the axial direction of the rotation shaft 41 of the suction roller 40c, and the suction force for sucking the suction chamber 53 as follows. To control.

  Referring to FIG. 36A, the controller 140 relates to the suction chambers 53 facing the holding member 60 from which the sheet material 11 is detached, among the suction chambers 53 partitioned along the circumferential direction of the rotation shaft 41. The operation of the compressor 271 is controlled so that the positive pressure 271a is supplied to the suction chamber 53.

  As shown in the figure, the controller 140 controls the operation of the compressor 271 so as to supply the positive pressure 271a to the sixth circumferential suction chamber 53 (v6) where the sheet material 11 starts to be detached. In the illustrated example, the positive pressure 271a is also supplied to the seventh circumferential suction chamber 53 (v7) so as not to cause a delay in the separation of the sheet material 11.

  By controlling the supply of positive pressure to the suction chamber 53 partitioned along the circumferential direction of the rotation shaft 41 of the suction roller 40c as described above, the bonding force between the support sheet 13 and the sheet material 11 at the time of separation ( The suction force of the suction roller 40 can be made weaker than the pasting force). As a result, in the winding (detaching) step, the support sheet 13 can be attached to the sheet material 11 and detached from the suction roller 40c without causing problems such as air entrainment and mixing and generation of wrinkles. By changing from the suction behavior of the suction roller 40c to the air injection behavior by positive pressure, the separation of the sheet material 11 from the suction roller 40c is promoted, and the joining of the sheet material 11 to the support sheet 13 is promoted. Can do.

  Referring to FIG. 36 (B), the controller 140 faces the holding member 60 that comes into contact with both end edges in the axial direction of the sheet material 11 in the suction chamber 53 partitioned along the axial direction of the rotating shaft 41. The operation of the compressor 271 is controlled so that a positive pressure is supplied to the suction chambers 53 with respect to the suction chambers 53 located inside the suction chambers 53.

  In FIG. 36B, a plurality of suction chambers 53 are represented in 8 rows and 5 columns. The row direction is the seventh, sixth, fifth, fourth, third, second, first, and eighth circumferential suction chambers 53 (v7), 53 (v6) in order from the bottom to the top. ), 53 (v5), 53 (v4), 53 (v3), 53 (v2), 53 (v1), 53 (v8). The column direction indicates the first to fifth axial suction chambers 53 (h1) to 53 (h5) in order from left to right. In the cell, “strong”, “medium”, and “weak” of the positive pressure 271a are shown. A blank cell indicates a state in which a negative pressure is supplied. A cell with “medium” is stronger than the state where the positive pressure is “weak”, and a cell with “strong” is even stronger than the state where the positive pressure is “medium”.

  The first axial suction chamber 53 (h1) and the fifth axial suction chamber 53 (h5) correspond to the suction chamber 53 in which the holding members 60 that are in contact with both end edges of the sheet material 11 face the second chamber. The fourth axial suction chambers 53 (h2) to 53 (h4) correspond to the suction chamber 53 on the inner side of the suction chamber 53 facing the holding member 60 with which both end edges of the sheet material 11 are in contact. Reason for supplying positive pressure 271a to the second to fourth axial suction chambers 53 (h2) to 53 (h4) inside the first and fifth axial suction chambers 53 (h1) and 53 (h5) Is as follows. Air of positive pressure 271a supplied to the suction chamber 53 passes through the holding member 60, passes between the holding member 60 and the sheet material 11, and forms an air flow that is discharged into the atmosphere from both ends of the sheet material 11. It is to do. As long as such an air flow can be formed, the supply form of the positive pressure 271a can be appropriately employed. For example, compared with the positive pressure supplied to the outer first and fifth axial suction chambers 53 (h1) and 53 (h5), the second to fourth axial suction chambers 53 (h2) to 53 on the inner side. The above air flow can be formed by increasing the positive pressure supplied to (h4). As shown in the drawing, the controller 140 has the first and fifth axial suction chambers 53 on the outer side in the row (second stage from the bottom) of the sixth circumferential suction chamber 53 (v6) from which the sheet material 11 is detached. The compressor 271 is set so that the positive pressure supplied to the inner second to fourth axial suction chambers 53 (h2) to 53 (h4) is stronger than the positive pressure supplied to the (h1) and 53 (h5). Control the operation of Row of fifth circumferential suction chamber 53 (v5) (third stage from the bottom), row of fourth circumferential suction chamber 53 (v4) (fourth stage from the bottom), third circumferential suction chamber 53 Also in the row (v3) (the 54th row from the bottom), the strength of the positive pressure supplied to each suction chamber 53 is controlled so as to form the above air flow. In the illustrated example, the first to fifth axial suctions are performed in the row (bottom row) of the seventh circumferential suction chamber 53 (v7) in order to prevent a delay in the separation of the sheet material 11. The positive pressure supplied to the chambers 53 (h1) to 53 (h5) is a strong positive pressure. The above-described control of the positive pressure supplied to the first to fifth axial suction chambers 53 (h1) to 53 (h5) is only an example, and the first to first are controlled according to the state of separation of the sheet material 11. The supply of positive pressure to the five axial suction chambers 53 (h1) to 53 (h5) can be appropriately varied.

  By controlling the supply of the positive pressure 271a to the suction chamber 53 partitioned along the axial direction of the rotation shaft 41 of the suction roller 40c as described above, the bonding force between the support sheet 13 and the sheet material 11 at the time of separation. The suction force of the suction roller 40c can be made weaker than (sticking force). As a result, in the winding (detaching) step, the support sheet 13 can be attached to the sheet material 11 and detached from the suction roller 40c without causing problems such as air entrainment and mixing and generation of wrinkles. By forming an air flow from the central portion of the sheet material 11 to the outside of both end edges, the bonding of the sheet material 11 to the support sheet 13 is improved.

  The controller 140 controls the operation of the switching valve 124 and switches the connection destination to the vacuum pump 123 or the compressor 271. Therefore, for the suction chamber 53 that supplies the positive pressure 271a, the controller 140 controls the operation of the suction portion 120 so as to stop the suction of these suction chambers 53. Since the suction is stopped and the positive pressure 271a is supplied, the operating energy loss of the vacuum pump 123 and the compressor 271 can be reduced.

  Thus, the suction chamber 53 is partitioned along both the circumferential direction and the axial direction of the rotation shaft 41 of the suction roller 40c. The sheet material manufacturing apparatus further includes a compressor 271 (supply unit) that supplies a positive pressure 271a to each suction chamber 53, and the controller 140 supplies the positive pressure 271a to each suction chamber 53 by the compressor 271. The operation of the compressor 271 is controlled so as to be switched. Then, the controller 140 is arranged along the axial direction of the rotation shaft 41 and the suction chamber 53 facing the holding member 60 from which the sheet material 11 is detached, among the suction chambers 53 partitioned along the circumferential direction of the rotation shaft 41. Among the divided suction chambers 53, positive pressure 271 a is applied to these suction chambers 53 with respect to the suction chambers 53 facing the holding chamber 60 facing the holding members 60 that are in contact with both edges of the sheet material 11 along the axial direction. The operation of the compressor 271 is controlled so as to be supplied.

  With this configuration, the suction force of the suction roller 40c can be made weaker than the joining force (sticking force) between the support sheet 13 and the sheet material 11 at the time of separation. As a result, in the winding (detaching) step, the support sheet 13 can be attached to the sheet material 11 and detached from the suction roller 40c without causing problems such as air entrainment and mixing and generation of wrinkles. Since the ejection for separating the sheet material 11 can be finely controlled for each suction chamber 53, the detachability or peelability of the sheet material 11 can be improved.

  Further, with respect to the suction chamber 53 that supplies positive pressure, the operation of the suction unit 120 is controlled so as to stop the suction of these suction chambers 53.

  With this configuration, the amount of suction is reduced, so that the sheet material 11 can be easily detached. Further, since the suction is stopped and the positive pressure is supplied, the loss of operating energy of the vacuum pump 123 and the compressor 271 can be reduced.

(Example of measures taken when sheet material is removed (2))
FIG. 37 is a perspective view showing a modified example of the frame 250b, and FIG. 38 is a cross-sectional view showing a suction roller 40d to which the frame 250b shown in FIG. 37 is applied.

  The trouble countermeasure example (2) at the time of separation of the sheet material is such that the controller 140 controls the supply of the positive pressure 271a in that the suction when the sheet material 11 is detached by an operation like a pendulum is stopped. This is different from the trouble countermeasure example (1).

  Referring to FIGS. 37 and 38, the configuration of the problem countermeasure example (2) will be outlined. The frames 250b are rotatably mounted in the respective suction chambers 53 and are rotated as the frames 250b are rotated. A shutter 280 is provided. The shutter 280 has a structure that rotates to a position where the communication between the holding member 60 and the suction portion 120 is cut off in the suction chamber 53 where the holding member 60 that the separated sheet material 11 begins to leave faces. .

  More specifically, the frame 250b defines eight suction chambers 53 (a general term for 53 (1) to 53 (8)) in the circumferential direction. A holding member 60 is attached to face each suction chamber 53. The shutter 280 has a plate shape, and a base end portion 280a is rotatably connected to a wall portion 281 that partitions the suction chamber 53 via a rotation mechanism such as a hinge. The base end portion 280a is connected to the wall surface on the downstream side along the rotation direction of the frame 250b among both surfaces of the wall portion 281. The proximal end portion 280a extends and is connected in parallel to the rotation shaft 41 of the frame 250b at a substantially central position in the radial length of the wall portion 281. The width of the shutter 280 is substantially the same as the inner width of the suction chamber 53 along the axial direction of the rotation axis of the frame 250b. A weight 280b is attached to the distal end facing the base end 280a. One shutter 280 is provided in each of the suction chambers 53. The rotation mechanism to which the base end portion 280a is connected is a free rotation shaft, and the shutter 280 rotates according to the rotation position of the frame 250b.

  The initial state of the shutter 280 is set to a state in which the weight 280b leans against the wall portion 281 to which the base end portion 280a is connected (state in the suction chambers 53 (8) and 53 (1) to 53 (3)). As the frame 250b rotates in the clockwise direction in FIG. 38, the shutter 280 rotates from the initial state in the clockwise direction in which the weight 280b is separated from the wall portion 281 by the action of gravity (suction chamber 53 ( 4)). The weight 280b falls into the adjacent wall portion 281 that faces the wall portion 281 to which the base end portion 280a is connected. In this state, the shutter 280 partitions the suction chamber 53 into a space facing the holding member 60 and a space facing the rotation shaft 41 of the frame 250b (state in the suction chambers 53 (5) and 53 (6)). . When the frame 250b further rotates, the weight 280b separates from the adjacent wall portion 281 and freely hangs down in the suction chamber 53 (state in the suction chamber 53 (7)). In this state, the shutter 280 opens the partition of the suction chamber 53. When the frame 250b further rotates, the weight 280b leans against the wall portion 281 to which the base end portion 280a is connected and returns to the initial state (state in the suction chamber 53 (8)).

  As shown in FIG. 6, the negative pressure path 56 in the suction roller 40 d includes an axial path 57 formed in the rotary shaft 41 and a radial path that is opened in the outer peripheral surface of the rotary shaft 41 and communicates with the axial path 57. 58.

  Therefore, when the shutter 280 partitions the suction chamber 53, the shutter 280 rotates to a position where the communication between the holding member 60 and the suction unit 120 is blocked.

  The shutter 280 is a position where the communication between the holding member 60 and the suction unit 120 is blocked in the suction chamber 53 (6) where the holding member 60 that the sheet material 11 released through the take-up roller 90 begins to leave. It has been rotated. Accordingly, the suction force of the suction roller 40 can be made weaker than the bonding force (sticking force) between the support sheet 13 and the sheet material 11 at the time of separation. As a result, in the winding (detaching) step, the support sheet 13 can be attached to the sheet material 11 and separated from the suction roller 40 without causing problems such as air entrainment and mixing, and generation of wrinkles. In the illustrated example, the shutter 280 also blocks the communication between the holding member 60 and the suction part 120 in the suction chamber 53 (5) so that the release of the sheet material 11 is not delayed. It has been rotated.

  When the shutter 280 is at an arbitrary angle and position, the weight 280b hangs down due to the weight, thereby covering the suction chamber 53. By closing the lid, communication between the holding member 60 and the suction part 120 is blocked. Further, since the shutter 280 is rotationally driven by gravity acting on the weight 280b, the lid in the suction chamber 53 is opened again at an arbitrary angle and position, and suction of the suction chamber 53 can be resumed. . Thus, by a simple operation such as a pendulum of the shutter 280 provided in the suction chamber 53, the suction of the sheet material 11 can be stopped at an arbitrary angle and position in the winding (detaching) step.

(Example of measures taken when sheet material is removed (3))
39 is a partially exploded perspective view showing a modification of the suction roller 40e. FIGS. 40A and 40B are front views showing a suction control plate 290 incorporated in the suction roller 40e. FIG. B is a front view showing a guide plate 292 incorporated in the suction roller 40e, and FIGS. 42A and 42B are explanatory views for explaining a suction operation.

  The countermeasure example (3) at the time of separation of the sheet material is to stop the suction when the sheet material 11 is separated by the combination of the non-rotational suction control plate 290 and the guide plate 292 that rotates in synchronization with the rotation of the suction roller 40e. In the point made to do so, the trouble countermeasure example (1) in which the supply of the positive pressure 271a is controlled by the controller 140, the trouble that the suction when the sheet material 11 is detached by the operation like a pendulum is stopped This is different from the countermeasure example (2).

  Referring to FIGS. 39 to 42, the configuration of the countermeasure example (3) is outlined. The suction roller 40 e is configured so that the opening region 290 a communicating with the suction chamber 53 and the non-opening region blocking communication with the suction chamber 53. And a non-rotating suction control plate 290 having 290b, and a guide plate 292 in which a plurality of opening holes 293 communicating with each of the suction chambers 53 through the opening region 290a of the suction control plate 290 are formed. The guide plate 292 rotates in synchronization with the rotation of the suction roller 40e, and the suction unit 120 is connected to the opening hole 293. In the position where the suction control plate 290 and the guide plate 292 adsorb the sheet material 11 to the suction roller 40e, the opening hole 293 of the guide plate 292 faces the opening region 290a of the suction control plate 290, and the sheet material from the suction roller 40e. 11 has a structure in which the opening hole 293 of the guide plate 292 faces the non-opening region 290b of the suction control plate 290 at the position where the 11 is detached.

  More specifically, with reference to FIGS. 40A and 40B, the suction control plate 290 has a disk shape and is formed with a plurality of grooves 291 having an arc shape penetrating therethrough. The plurality of grooves 291 are opened concentrically while being separated in the radial direction at an arbitrary pitch. The suction control plate 290 is not formed with a groove in an arbitrary angle range. A portion where the groove 291 is formed corresponds to the opening region 290a, and a portion where the groove is not formed corresponds to the non-opening region 290b, which is a range where suction is stopped.

  Referring to FIGS. 41A and 41B, guide plate 292 has a disk shape and is formed with a plurality of opening holes 293 extending therethrough. The opening holes 293 are opened at a constant angular pitch (x). This angle (x) is the same as the angle formed by the adjacent suction chambers 53. The opening holes 293 are displaced outward in the radial direction every time one pitch is displaced. This opening hole deviation amount (y) is equivalent to the pitch deviation amount (z) of the groove 291 of the suction control plate 290. The diameter of the opening hole 293 is equal to or smaller than the groove width of the groove 291.

  The frame 250 and the holding member 60 are configured in the same manner as shown in FIG. The frame 250 and the guide plate 292 are rotated by the rotation shaft 41. The suction control plate 290 is fixed by a gantry or the like and is a non-rotating body.

  The material for forming the suction control plate 290 and the guide plate 292 is not particularly limited, but can be formed from stainless steel, for example. It is necessary to increase the surface accuracy between the suction control plate 290 and the guide plate 292 and between the suction control plate 290 and the frame 50. Therefore, it is preferable to select a material having high hardness and easy surface finishing. In addition, when used in a clean room or the like, it is preferable to select a material with excellent wear resistance because no lubricating oil such as grease or oil is used.

  42 (A) and 42 (B), in the range in which the groove 291 of the suction control plate 290 is formed from the relationship between the position of the groove 291 of the suction control plate 290 and the position of the opening hole 293 of the guide plate 292. In order, the opening holes 293 of the guide plate 292 are switched every angular pitch. Thus, when the opening hole 293 of the guide plate 292 faces the opening region 290a of the suction control plate 290, the suction of the suction chamber 53 is continued, and the sheet material 11 is sucked to the suction roller 40e.

  If the opening hole 293 of the guide plate 292 reaches the range where the groove 291 of the suction control plate 290 is not present, the communication between the suction chamber 53 and the suction unit 120 is blocked. Thus, when the opening hole 293 of the guide plate 292 faces the non-opening region 290b of the suction control plate 290, the suction of the suction chamber 53 is stopped, and the sheet material 11 can be easily detached from the suction roller 40e. The suction of the suction chamber 53 is stopped, but the surface of the holding member 60 is covered with the sheet material 11. For this reason, the suction chamber 53 is maintained in a vacuum state to some extent. However, since the suction of the suction chamber 53 is stopped, the vacuum state can be easily released or broken by the peeling force in the step of removing the sheet material 11 from the suction roller 40e, and the sheet material 11 can be easily peeled off. it can. As a result, in the winding (detaching) step, the support sheet 13 can be attached to the sheet material 11 and detached from the suction roller 40e without causing problems such as air entrainment and mixing and generation of wrinkles.

  Further, by providing the suction control plate 290 between the frame 250 and the guide plate 292, the suction of the suction chamber 53 can be stopped at an arbitrary angle and position. Thus, by the combination of the non-rotating suction control plate 290 and the rotating guide plate 292, the suction of the sheet material 11 can be stopped at an arbitrary angle and position in the winding (detaching) step.

(Problem countermeasure example when coating material is dried (1))
FIG. 43 is a schematic configuration diagram showing the negative pressure path 121e and the dry gas supply path 300 of the suction unit 120.

  The drying unit 110 dries the applied catalyst ink from its surface side by hot air drying or the like. When the applied coating material is dried only from the surface side, only the dried surface contracts, tension is generated, and defects such as cracks and pinholes may occur. In order to suppress the occurrence of defects such as cracks, it is effective not only to dry the applied coating material from the front side but also from the back side.

  As a countermeasure example (1) when the coating material is dried, the case of the suction roller 40a to which the frame 250 shown in FIG. 23 is applied will be described as an example. As shown in FIG. 23, the frame 250 of the suction roller 40 a has a suction port 256 that opens into a gap S that exists between adjacent holding members 60. The suction port 256 is connected to the suction part 120 and has a structure that generates a negative pressure that attracts the sheet material 11 covering the gap S.

  Referring to FIG. 43, the sheet material manufacturing apparatus further includes a compressor 301 as a dry gas supply unit that supplies dry gas to each suction chamber 53. The controller 140 controls the operation of the compressor 301 so as to switch the state in which the dry gas is supplied to each suction chamber 53 by the compressor 301. In addition, the sheet material manufacturing apparatus has a structure in which dry gas can be supplied to the gap S from the suction port 256. The sheet material manufacturing apparatus further includes a temperature adjusting unit 302 that adjusts the temperature of the drying gas. The controller 140 controls the operation of the temperature adjustment unit 302 so as to adjust the temperature of the drying gas. The temperature adjustment unit 302 includes a heater and a cooler, and can set the temperature of the dry gas supplied to the suction chamber 53 and the gap S to a desired temperature from hot air to cold air. In order to carry out the drying process while the sheet material 11 is adsorbed to the adsorption roller 40a, the positive pressure of the drying gas is set to an appropriate strength that does not inhibit the adsorption of the sheet material 11.

  The negative pressure path 121e of the suction unit 120 includes an electropneumatic regulator 122 provided for each suction chamber 53 and one vacuum pump 123 to which each electropneumatic regulator 122 is connected. In the negative pressure path 121e, one electropneumatic regulator 122 is connected to one suction chamber 53 and to one suction port 256. Each electropneumatic regulator 122 can arbitrarily set a suction pressure value by program control. Each electropneumatic regulator 122 is connected to the controller 140, and a control signal indicating a suction pressure value is input from the controller 140. With such a configuration, the suction amount of each suction chamber 53 and each gap S can be controlled independently, and the state of sucking each suction chamber 53 and each gap S can be switched.

  The negative pressure path 121e of the suction unit 120 can be selectively connected to a vacuum pump 123 and a compressor 301 as a dry gas supply unit via a switching valve 124. The type of dry gas supplied by the compressor 301 is not particularly limited, but air can be used. The controller 140 controls the operation of the compressor 301 so as to switch the state in which the dry gas is supplied to each suction chamber 53 by the compressor 301. That is, the controller 140 controls the operation of the switching valve 124 and automatically switches the connection destination to the vacuum pump 123 or the compressor 301. Thereby, the suction of the suction chamber 53 and the supply of the dry gas to the suction chamber 53 and the gap S can be switched.

  The controller 140 controls the operation of the drying gas supply unit 300 so as to supply the drying gas to the suction chamber 53 facing the holding member 60 with which the sheet material 11 is in contact. The dry gas supplied to the suction chamber 53 passes through the holding member 60 and contacts the back surface of the sheet material 11. Further, the dry gas is supplied to the gap S from the suction port 256 and comes into contact with the back surface of the sheet material 11 covering the gap S. Accordingly, the coating material applied to the sheet material 11 while the sheet material 11 is adsorbed to the adsorption roller 40a is dried by the drying unit 110 on the front surface side and dried by a dry gas on the back surface side. Since the coating material can be dried not only from the front side but also from the back side, the occurrence of defects such as cracks and pinholes can be suppressed.

  The temperature of the drying gas can be arbitrarily changed by the temperature adjustment unit 302, and the amount of heating from the back side can be easily adjusted. For this reason, the degree of drying on the back side can be easily adjusted.

  In addition, although the example which supplies dry gas to both the suction chamber 53 and the clearance gap S was shown, it shall be set as the structure which supplies dry gas only to the suction chamber 53 in consideration of the area which adsorb | sucks the sheet | seat material 11. FIG. Can do.

(Example of countermeasures for drying coating materials (2))
44A and 44B show the adsorption of the sheet material 11 and the supply of the dry gas when the suction chamber 53 is partitioned along both the circumferential direction and the axial direction of the rotation shaft 41 of the adsorption roller 40c. It is explanatory drawing demonstrated.

  The countermeasure example (2) for drying the coating material is that the drying gas is supplied to some of the suction chambers 53 of the suction chamber 53 facing the holding member 60 that is in contact with the sheet material 11. This is different from the problem countermeasure example (1) in which the dry gas is supplied to all the suction chambers 53 facing the holding member 60 in contact with the sheet material 11.

  44 (A) and 44 (B), the problem countermeasure example (2) is outlined. The suction chamber 53 is partitioned along both the circumferential direction and the axial direction of the rotation shaft 41 of the suction roller 40c. 140 controls the operation of the dry gas supply unit 301 so that the dry gas is supplied to some of the suction chambers 53 of the suction chamber 53 facing the holding member 60 that the sheet material 11 is in contact with. .

  As shown in FIG. 31, in the suction roller 40c, the suction chamber 53 is partitioned along both the circumferential direction and the axial direction of the rotation shaft 41 of the suction roller 40c. As shown in FIGS. 33 (A) and 36 (A), the circumferential suction chamber 53 facing the holding member 60 in contact with the sheet material 11 is the first to sixth circumferential suction chambers. 53 (v1) to 53 (v6). The coating material is applied to the sheet material 11 at a position between the first circumferential suction chamber 53 (v1) and the second circumferential suction chamber 53 (v2). In such a case, the dry gas can be supplied at a position from the second circumferential suction chamber 53 (v2) to the sixth circumferential suction chamber 53 (v6).

  The negative pressure path 121e and the dry gas supply path 300 of the suction unit 120 are configured in the same manner as shown in FIG. However, the suction roller 40c is also coupled to the roller structure 265 in the cylindrical height direction. Accordingly, a similar negative pressure path 121e and dry gas supply path 300 are also provided in the cylinder height direction. As a result, the dry gas can be supplied at an arbitrary position with an arbitrary air volume.

  44 (A) and 44 (B), the suction chamber 53 facing the holding member 60 in contact with the sheet material 11 is represented in 5 rows and 5 columns. The row direction indicates the second to sixth circumferential suction chambers 53 (v2) to 53 (v6) in order from the bottom to the top, and the column direction corresponds to the first in order from the left to the right. To fifth axial suction chambers 53 (h1) to 53 (h5).

  In the example shown in FIG. 44A, the controller 140 includes a part of the suction chambers denoted by “d” in the suction chamber 53 facing the holding member 60 that is in contact with the sheet material 11. The operation of the dry gas supply unit 300 is controlled so as to supply the dry gas to 53. The controller 140 sucks the remaining suction chambers 53 denoted by “s” and sucks the sheet material 11. The dry gas supplied to a part of the suction chambers 53 labeled “d” passes through the holding member 60 and contacts the back surface of the sheet material 11. Accordingly, the coating material applied to the sheet material 11 while the sheet material 11 is adsorbed to the adsorption roller 40c is dried by the drying unit 110 on the front surface side and dried by a dry gas on the back surface side. Since the coating material can be dried not only from the front side but also from the back side, the occurrence of defects such as cracks and pinholes can be suppressed.

  In the example shown in FIG. 44 (B), the controller 140 has the signs “d (strong)” and “d (weak) among the suction chambers 5 facing the holding member 60 in contact with the sheet material 11. The operation of the dry gas supply unit 300 is controlled so that the dry gas is supplied to some of the suction chambers 53 marked with "." The suction chamber 53 with “d (strong)” has a higher positive pressure of the dry gas than the suction chamber 53 with “d (weak)”. The suction chamber 53 (“d (strong)”) having a strong positive pressure of the dry gas is set so as to approach the center portion. This is because the dry gas flows from the central portion of the sheet material 11 toward the periphery. The controller 140 sucks the remaining suction chambers 53 denoted by “s (strong)” and “s (weak)”, and sucks the sheet material 11. The suction chamber 53 with “s (strong)” has a stronger suction force than the suction chamber 53 with “s (weak)”. The dry gas supplied to a part of the suction chambers 53 labeled “d (strong)” and “d (weak)” passes through the holding member 60 and contacts the back surface of the sheet material 11. Accordingly, the coating material applied to the sheet material 11 while the sheet material 11 is adsorbed to the adsorption roller 40c is dried by the drying unit 110 on the front surface side and dried by a dry gas on the back surface side. Since the coating material can be dried not only from the front side but also from the back side, the occurrence of defects such as cracks and pinholes can be suppressed.

  As shown in FIGS. 44 (A) and 44 (B), the suction and spraying of the dry gas can be changed depending on the location of the suction chamber 53. As shown in FIG. The strength of the positive pressure of the gas can be varied depending on the location of the suction chamber 53. By making the positive pressure level of the drying gas variable, the amount of heating from the back side can be easily adjusted, and the degree of drying on the back side can be easily adjusted.

(Modification example of supply mechanism (1) (2))
45A and 45B are diagrams for explaining a modification example (1) of the supply mechanism, and FIGS. 46A and 46B are diagrams for explaining a modification example (2) of the supply mechanism.

  As an example of the supply mechanism that supplies the sheet material 11 to the suction roller 40, the unwinding roller 80 that contacts the suction roller 40 via the sheet material 11 is given as an example. However, the supply mechanism is not limited to this case. The modification examples (1) and (2) of the supply mechanism are different from the above-described embodiment in which the roller member is applied in that the blade member is applied.

  When a roller member (unwinding roller 80) is applied as the supply mechanism, the rotation axis of the roller member may be decentered from a state parallel to the rotation axis of the suction roller 40. In such a case, the pressing force of the roller member against the suction roller 40 varies depending on the position in the rotation axis direction. As a result, the sheet material 11 is biased and pushed to change its shape, and the thickness of the sheet material 11 varies depending on the position in the rotation axis direction.

  45 (A) and 45 (B), in the modification example (1) of the supply mechanism, a pressing blade 310 as a blade member pressed against the suction roller 40 via the sheet material 11 is provided in the supply mechanism. Applicable. By adopting a method of pressing the blade member, the surface that presses the sheet material 11 has a high accuracy straightness determined only by the manufacturing accuracy of the blade member without being affected by the drive accuracy and tolerance of the drive mechanism parts. It becomes a prepared surface. Further, since it can be pressed with high accuracy, the blade material can be selected from metal materials, and the blade member can be manufactured with higher accuracy. By applying the pressing blade 310 in this way, the shape of the sheet material 11 is stabilized, and the thickness of the sheet material 11 can be made uniform regardless of the position in the rotation axis direction.

  46A and 46B, in the modification example (2) of the supply mechanism, gas 311a (for example, air) that presses the sheet material 11 against the suction roller 40 is ejected to the supply mechanism. An air blade 311 as a blade member is applied. The air outlet of the air blade 311 has a knife shape. By adopting a system in which the gas 311 a is blown from the blade member, the sheet material 11 can be pressed against the suction roller 40 to assist the suction of the sheet material 11 to the suction roller 40. When the peeling force of the support sheet 12 is strong, the suction force of the suction roller 40 is increased to further assist the suction of the sheet material 11 to the suction roller 40. The sheet material 11 can be uniformly pressed against the suction roller 40 in a non-contact state with the sheet material 11 by the air 311 a ejected from the air blade 311. By applying the air blade 311 in this way, the shape of the sheet material 11 is stabilized, and the thickness of the sheet material 11 can be made uniform regardless of the position in the rotation axis direction.

(Example of modification of separation mechanism)
47A, 47B, 47C, 47D are diagrams for explaining a modification example of the separation mechanism.

  Although the take-up roller 90 that contacts the suction roller 40 via the sheet material 11 has been described as an example of the release mechanism for releasing the sheet material 11 from the suction roller 40, the release mechanism is not limited to this case. The modification example of the separation mechanism is different from the above-described embodiment in which the roller member is applied in that the blade member is applied.

  When a roller member (winding roller 90) is applied as the separation mechanism, the rotation axis of the roller member may be decentered from a state parallel to the rotation axis of the suction roller 40. In such a case, the pressing force of the roller member against the suction roller 40 varies depending on the position in the rotation axis direction. As a result, the support sheet 13 is pushed unevenly and the support sheet 13 is peeled off, or the coating film on the sheet material 11 is pushed and pushed, and the shape changes, and the thickness of the coating film changes in the rotation axis direction. There is a problem that it varies depending on the position.

  47A and 47B, in the modified example of the separation mechanism, a pressing blade 320 as a blade member pressed against the suction roller 40 via the sheet material 11 is applied to the separation mechanism. Yes. By adopting a method of pressing the blade member, the surface on which the sheet material 11 is pressed has a high accuracy straightness determined only by the manufacturing accuracy of the blade member without being affected by the rotation accuracy and the tolerance of the rotating body parts. It becomes a prepared surface. Moreover, since it can press with high precision, a blade material can be selected from a metal-type material and a heat transfer rate improves. By applying the pressing blade 320 in this manner, the support sheet 13 is not peeled off, the shape of the coating film is changed, and the thickness of the coating film can be made uniform regardless of the position in the rotation axis direction.

  As shown in FIG. 47 (C), the pressing blade 320 has a structure capable of a small amount of swinging operation, or as shown in FIG. 47 (D), the pressing blade 320 has a structure capable of a small amount of vertical movement. can do. By the friction effect accompanying these operations, it is possible to assist the attachment (adhesion) of the sheet material 11 to the support sheet 13.

(Modification of drying process (1))
FIG. 48 shows a sheet material having a structure capable of performing a second drying process on the sheet material 11 separated from the adsorption roller 40 in addition to the first drying process on the sheet material 11 adsorbed on the adsorption roller 40. 49A and 49D are diagrams for explaining a drying process performed by the sheet material manufacturing apparatus 200a shown in FIG.

  Although the embodiment in which the drying process is not performed on the sheet material 11 separated from the suction roller 40 has been described, the present invention is not limited to this case. A drying process may be performed before the sheet material 11 separated from the adsorption roller 40 is wound around the product roller 30.

  48, in addition to the first drying process for the sheet material 11 adsorbed by the adsorption roller 40, the sheet material manufacturing apparatus 200a releases the sheet from the adsorption roller 40 and winds up the product roller 30. It has a structure capable of performing the second drying step on the material 11. The sheet material manufacturing apparatus 200a conveys the sheet material 11 on which the drying unit 110 that performs the first drying process, the other drying unit 330 that performs the second drying process, and the support sheet 13 are bonded together. Part 331. The type of the other drying unit 330 is not particularly limited as in the case of the drying unit 110, but for example, hot air drying, slit nozzle drying, IR drying, IH drying, or the like can be selected. The conveyance part 331 is comprised from a conveyance roller, a belt conveyor, etc. The coating material is dried in a two-stage manner including a first drying step and a second drying step. Thus, in the case of two-stage drying, the temperature condition in the first drying step and the temperature condition in the second drying step can be appropriately set to desired temperature conditions, respectively. In the illustrated example, the drying mode is a two-stage type. However, by providing two or more drying steps for the sheet material 11 until the sheet material 11 is separated from the adsorption roller 40 and wound around the product roller 30, the drying mode is set to a three-stage mode. It can be more than an expression.

  Due to the heating of the sheet material 11 on the suction roller 40, the frame 50 and the holding member 60 formed of a porous body are also warmed, causing thermal deformation, which may increase the amount of eccentricity of the suction roller 40. When the amount of eccentricity of the suction roller 40 increases, the thickness of the sheet material 11 varies as described above. Therefore, the first drying step is performed in a heated state that does not increase the amount of eccentricity of the suction roller 40, or in a normal temperature. The second drying step is performed in a necessary heating state after the support sheet 13 is bonded to the sheet material 11.

  As shown in FIGS. 49 (A) and 49 (B), the coating material (coating film 15) applied on the sheet material 11 is not contracted or cracked only in the very surface portion 15a in the first drying step. Dried to the extent. Next, as shown in FIGS. 49C and 49D, the support sheet 13 is bonded to the sheet material 11 separated from the suction roller 40, and then the support sheet 13 is sufficiently dried in the second drying step. .

  In this way, the sheet material manufacturing apparatus 200a is disposed at a position downstream of the take-up roller 90 as the separation mechanism in the transport direction of the sheet material 11, and performs other drying to dry the applied coating material. A part 330 is further provided.

  If comprised in this way, the temperature conditions of the drying part 110 which performs the drying process with respect to the sheet material 11 on the adsorption | suction roller 40, and the temperature conditions of the other drying part 330 which performs the drying process with respect to the sheet | seat material 11 after detachment | leave Can be appropriately set to desired temperature conditions. For example, the drying temperature in the drying unit 110 can be set lower than the drying temperature in the other drying unit 330, and the thickness of the sheet material 11 can be made uniform by suppressing the eccentric amount of the suction roller 40.

(Modification of drying process (2))
FIG. 50 is a schematic configuration diagram of a sheet material manufacturing apparatus 200b having a structure with a relatively long drying process length, and FIG. 51 adds a post-process to be performed after the drying process to the sheet material manufacturing apparatus 200b shown in FIG. It is a figure for demonstrating the state which carried out.

  As described above, the suction roller can be increased in diameter. It is possible to provide a sheet material manufacturing apparatus 200b having a structure in which a drying process length is relatively long while a space for installation is reduced by passing a porous belt around a plurality of large-diameter adsorption rollers. it can.

  Referring to FIG. 50, the sheet material manufacturing apparatus 200b includes a plurality of suction rollers 340, a porous belt 341, a supply mechanism 342, a separation mechanism 343, a coating unit 344, a drying unit 345, and a suction unit. Part 346. The plurality of suction rollers 340 convey the sheet material 11 by rotating in a state where the porous belt 341 is stretched and the sheet material 11 is sucked and held on the porous belt 341. The unwinding roller 342 as a supply mechanism contacts the porous belt 341 via the sheet material 11 and supplies the sheet material 11 to the porous belt 341. The take-up roller 343 as a detaching mechanism contacts the porous belt 341 via the sheet material 11 and causes the sheet material 11 to be detached from the porous belt 341. The application unit 344 applies an application material to the sheet material 11 adsorbed and held by the porous belt 341. The drying unit 345 is disposed at a position downstream of the coating unit 344 in the transport direction of the sheet material 11 in the porous belt 341, and dries the coated coating material. The suction unit 346 generates a negative pressure that causes the porous belt 341 to hold the sheet material 11 by suction. Each of the suction rollers 340 includes a rotatable frame 50 having a chamber 51 connected to the suction unit 346 and a plurality of holding members attached to the frame 50 in a state of being formed of a porous body and communicating with the chamber 51. 60. The peripheral surface of the suction roller 340 is formed by a plurality of holding members 60 attached to the frame 50.

  The porous belt 341 is made of, for example, a porous resin. The suction roller 340, the unwinding roller 342, the winding roller 343, the coating unit 344, the drying unit 345, and the suction unit 346 are respectively the suction roller 40, the unwinding roller 80, the winding roller 90, the coating unit 100, and the drying unit. 110 and the suction unit 120, the detailed description is omitted. The space facing the back surface side of the porous belt 341 is sucked by the suction portion 346, and a negative pressure that causes the porous material 341 to adsorb and hold the sheet material 11 is generated. The space facing the back side of the porous belt 341 is also sucked through the holding member 60 that does not adsorb the porous belt 341.

  Depending on the length of the porous belt 341, the length capable of adsorbing and conveying the sheet material 11 can be changed. In addition, the suction roller 340 can have a large diameter in the same manner as the suction roller 40. By spanning the porous belt 341 over a plurality of large-diameter suction rollers 340, the distance between the suction rollers 340 can be shortened compared to the case where the porous belt 341 is spanned over a plurality of small-diameter suction rollers. Can be achieved. Therefore, by spanning the porous belt 341 over a plurality of large-diameter adsorption rollers 340, a sufficient length of the drying process can be ensured while saving the installation pace.

  In addition, since it is easy to increase the length by which the sheet material 11 can be sucked and conveyed, the coating unit 344 made of a slit die coater or the like is not limited to horizontal coating, and is not limited by position restrictions such as undercoating and overcoating. Can be set to position.

  Since it is easy to increase the length of the sheet material 11 that can be sucked and conveyed, as shown in FIG. 51, the sheet material manufacturing apparatus 200b performs post-steps 347 and 348 performed after the drying step. It can be added before bonding. The post-processes 347 and 348 include, for example, a gasket attaching process and a gas diffusion layer (GDL) attaching process. In this way, the sheet material 11 can be transferred to the next process without bonding the support sheet 13.

  As described above, in the manufacturing apparatus 200b for the sheet material 11, the suction roller 340 is formed of the porous frame 50 having the chamber 51 connected to the suction unit 346 and the porous body, like the suction roller 40. And a plurality of holding members 60 which are attached to the frame 50 in a state where they communicate with the chamber 51. The circumferential surface of the suction roller 340 is formed by a plurality of holding members 60 attached to the frame 50. The porous belt 341 is stretched around the plurality of adsorption rollers 340.

  Moreover, in the manufacturing method of the sheet material 11 on which the coating film according to the present embodiment is formed, the sheet material 11 is supplied to the porous belt 341 that spans the plurality of suction rollers 340 configured as described above, The sheet material 11 is conveyed by rotating the adsorption roller 340 in a state where the sheet material 11 is adsorbed and held on the porous belt 341. The coating material is applied to the sheet material 11 adsorbed and held by the porous belt 341 by the coating unit 344, and the coating material is applied at a position downstream of the coating unit 344 in the conveyance direction of the sheet material 11 in the porous belt 341. The applied coating material is dried by the drying unit 345. Then, the sheet material 11 from which the coating material has been dried is detached from the porous belt 341.

  With this configuration, the suction roller 340 can have a large diameter as in the case of the suction roller 40, and the porous belt 341 is stretched around a plurality of large-diameter suction rollers 340, so that the installation pace can be increased. Providing a manufacturing apparatus 200b for a sheet material 11 with a coating film and a method for manufacturing the sheet material 11 with a coating film capable of ensuring a sufficiently long drying process length while saving space. it can.
