Description

  The present invention is a method for producing a composite substrate in which a sheet-like long substrate and a mesh-like long substrate are combined.

  Concrete is gradually neutralized by carbon dioxide in the air, but when neutralization proceeds to the inside of the concrete, the reinforcing bars corrode and the strength of the concrete structure is greatly reduced. Therefore, a method for attaching a protective sheet having weather resistance to the surface of a concrete structure has been proposed (for example, see Patent Document 1).

  On the other hand, there has also been proposed a method for preventing peeling when concrete deteriorates by attaching a mesh-like sheet to the concrete surface.

  An adhesive can be applied to each of these two types of sheets (base materials) using, for example, a coating apparatus as shown in Patent Document 2. And the function of surface protection and peeling prevention can be given to a concrete structure by sticking a mesh-like sheet | seat on the surface of a concrete structure part, and sticking a protective sheet which has a weather resistance after that.

Japanese Patent Laying-Open No. 2005-200958 JP 2006-95444 A

  However, in order to have a function of protecting the surface and preventing peeling of the concrete structure, it is necessary to attach a mesh-like sheet to the surface of the concrete structure and then attach a protective sheet as described above. was there.

  That is, it is necessary to stick two sheets (base materials) separately to the object, which requires a lot of man-hours.

  An object of the present invention is to provide a method for producing a composite base material capable of easily attaching two base materials to an object.

  In order to achieve the above object, a method for producing a composite base material according to the first invention is a method for producing a composite base material comprising a combination of a sheet-like long base material and a mesh-like long base material. A long continuous substrate supply step, a long mesh substrate supply step, a resin liquid application step, and a combination step are provided. The sheet-like long base material supplying step supplies a sheet-like long base material. The mesh-like long base material supplying step supplies a mesh-like long base material. In the resin liquid application step, the resin liquid is applied to the sheet-like long base material. In the combining step, the mesh-like base material is combined with the sheet-like long base material. In the sheet-like long base material supply process, resin coating process and combination process, a tensile stress of 1.4 kgf / m to 2.8 kgf / m per unit width is applied to the sheet-like long base material, and the mesh-like long base In the material supply step and the combination step, a tensile stress of 0.8 kgf / m to 2.0 kgf / m per unit width is applied to the mesh-like long base material.

  Thereby, since the resin liquid is already applied in a state where the mesh-like long base material is combined with the sheet-like long base material, two different base materials can be simultaneously attached to the object. For this reason, two base materials can be attached easily.

  Moreover, by applying the resin liquid in two stages, the resin liquid can be appropriately applied while integrating the sheet-like long base material and the mesh-like long base material.

  In addition, by setting the tensile stress applied to the sheet-like long base material and the tensile stress applied to the mesh-like long base material within a predetermined numerical range in this way, the composite base material while suppressing the generation of wrinkles Can be manufactured.

  Since the mesh-like long base material is an open base material, if a strong tensile stress is applied, the shape cannot be maintained, and the entire base material is distorted, causing kinking and wrinkles, Quality may not be ensured. Moreover, when the tensile stress added to a mesh-form long base material is high, the deviation with a sheet-like long base material will generate | occur | produce and the thickness nonuniformity of an adhesive agent may generate | occur | produce. Therefore, by making the tensile stress applied to the mesh-like long base material smaller than that of the sheet-like long base material, generation of wrinkles can be suppressed and a composite base material with good quality can be manufactured.

  The manufacturing method of the composite base material which concerns on 2nd invention is a manufacturing method of the composite base material concerning 1st invention, Comprising: In sheet-like long base material supply process, resin application process, and a combination process, sheet-like length A tensile stress of 1.8 kgf / m to 2.4 kgf / m per unit width is applied to the long base material, and 1.2 kgf per unit width is applied to the long mesh base material in the mesh long base material supplying process and the combining process. A tensile stress of / m to 1.6 kgf / m is applied.

  By setting the tensile stress applied to the sheet-like long base material and the tensile stress applied to the mesh-like long base material to a range narrower than the predetermined range of the first invention described above, the generation of wrinkles is further suppressed. And the composite base material which combined the sheet-like long base material and the mesh-like long base material can be manufactured.

  ADVANTAGE OF THE INVENTION According to this invention, the manufacturing method of the composite base material which can be easily affixed on the target object of two base materials can be provided.

The second applicator 102 applies the resin liquid r to the mesh-like long base material M combined with the sheet-like long base material F.

(1-2. First coating machine)
As shown in FIGS. 1A and 1B, the first applicator 101 includes a main body part 110, a leg part 120, and a first base roller support part 130. The main body 110 accommodates a first transport mechanism 200, a first guide roller 300, a first reservoir 400, a first position adjuster 500, and a first scraper 700 (see FIG. 2).

(1-2-1. First transport mechanism, first guide roller)
In the present embodiment, as shown in FIG. 2, the first transport mechanism 200 includes a first motor 210, a pair of feed rollers 220 and a first outlet roller 290, a roller 230, a motor gear (not shown), a guide roller gear, A feed roller gear and an exit roller gear.

  The pair of feed rollers 220 (the feed roller 221 and the driven shaft roller 222 arranged above the feed roller 221), the first guide roller 300, and the first outlet roller 290 are arranged in this order from the upstream, and both are the main body. It is pivotally supported by body frames 115 (see FIG. 1B) at both ends of the portion 110. As shown in FIG. 1B, a first drive unit 116 is continuously provided on one side of the main body frame 115 (facing the conveyance direction and on the right hand side). One motor 210 is accommodated.

  A rotating shaft of the first motor 210 protrudes from the inside of the first drive unit 116 in which the first motor 210 is accommodated into the one main body frame 115. In the one main body frame 115, the rotational driving force by the rotation shaft of the first motor 210 is transmitted to the shaft cores of the first guide roller 300, the pair of feed rollers 220, and the first outlet roller 290. A gear train is constituted by the roller gear, the feed roller gear, and the outlet roller gear.

  A first base roller R <b> 1 is fixed to the leg part 120 by a first base roller support part 130. As shown in FIG. 2, the sheet-like long base material F unwound from the first base roller R1 is stretched over a roller 230 and sandwiched between a pair of feed rollers 220. Further, the first guide roller It is stretched over the upper surface of 300 and the upper surface of the first outlet roller 290 and continuously conveyed. The sheet-like long base material F is not particularly limited, and may be a resin sheet or paper. Further, it may be a long base material including a base material made of a resin such as PET (polyethylene terephthalate) and a carbon film (for example, a diamond-like carbon film). In addition, a resin liquid is apply | coated to the opposite side to the carbon film of a long base material.

(1-2-2. Reservoir)
In the present embodiment, as shown in FIG. 2, a first reservoir 400 is disposed on the top of the first guide roller 300. The first reservoir 400 is a hopper whose longitudinal direction is the axial direction of the guide roller 300 (see arrow W in FIG. 1). The first reservoir 400 stores the resin liquid r received from the upper part and guides it from the supply port 430 opened at the lowermost part. The sheet 300 is dropped and supplied to the sheet-like long base material F disposed on the upper surface of the roller 300. Thereby, the effective resin liquid amount can be secured efficiently.

FIG. 3 is an enlarged view showing the vicinity of the first reservoir 400 and the first guide roller 300 of the first coating machine 101. The opening width in the longitudinal direction (see arrow W in FIG. 1) of the supply port 430 of the first reservoir 400 is equal to or less than the longitudinal direction (see arrow W) width of the first guide roller 300, and the sheet-like long base material F The resin application width (see arrow W) is determined. The opening width of the supply port 430 in the short direction (see arrow X) is both the inlet side (left side of the first guide roller 300 in FIG. 2 in this embodiment) and the outlet side (same right side) of the first guide roller 300. It straddles. In this embodiment, the center (see line Q1) of the opening width in the short direction (arrow X direction) of the supply port 430 is on the right side (conveying direction side (exit side) of the axis of the first guide roller 300 (see line Q2). )). Therefore, it is set larger than the distance L _E distance L _D of the outlet side of the inlet side of the supply port 430 and the first guide roller 300.

  In addition, the opening position of the supply port 430 of the 1st storage part 400 and the positional relationship of the 1st guide roller 300 and the supply port 430 are not limited to the aspect shown in figure. For example, the supply port 430 may be configured to open to the side surface of the first storage unit 400, and the position of the supply port 430 may be shifted laterally from the vertical upper part of the first guide roller 300. .

  The resin liquid r described above is not particularly limited, and examples thereof include an adhesive resin composition, a pigment resin composition, and a functional resin composition. Examples of the resin liquid r include an adhesive having elasticity after being cured, and a resin composition containing a modified silicone resin and an epoxy resin may be used.

  Further, as the resin liquid r, one having a thixo index of 2.5 or more and 6.5 or less can be used.

  Further, for example, the viscosity of the resin liquid r at 20 ° C. may be 20 Pa · s or more and 200 Pa · s or less. The viscosity is measured under a condition of 20 ° C. by a spring balance of the torque due to the viscous resistance of the resin with a single cylinder rotational viscometer in accordance with the JIS k 6833 adhesive general test method.

(1-2-3. Position adjustment unit)
A distance L (see FIG. 2) between the supply port 430 of the first storage unit 400 and the surface of the first guide roller 300 is configured to be movable by the first position adjustment unit 500. FIG. 4 is a diagram illustrating a configuration in the vicinity of the first position adjustment unit 500. In the present embodiment, the first position adjustment unit 500 includes a fixing unit 510 and an adjustment screw 520. The fixing portion 510 is fixed to the main body frame 115 in a stationary manner. The adjustment screw 520 connects the fixing part 510 and the holding part 450 extending from the first storage part 400.

  As shown in FIG. 4, the adjustment screw 520 is fixed to the fixing portion 510 on one end side, and holds the first storage portion 400 by sandwiching the holding portion 450 with the upper and lower nuts 530 on the other end side. . The first reservoir 400 is moved up and down by moving the position of the upper and lower nut 530 up and down.

  For example, when the position of the supply port 430 of the first storage unit 400 is P1 (see the one-dot chain line in FIG. 4), if the position of the upper and lower nuts 530 in the adjustment screw 520 is moved upward, When the holding part 450 is lifted, the first storage part 400 moves upward, and the position of the supply port 430 can be raised to P2. Thereby, the distance L (see FIG. 2) between the supply port 430 and the guide roller 300 can be increased, and the amount of the resin liquid supplied to the guide roller 300 can be increased. Thus, the resin supplied to the sheet-like long base material F on the guide roller 300 by a simple operation of adjusting the distance L between the supply port 430 and the first guide roller 300 by the first position adjusting unit 500. The amount can be easily determined.

  Since the amount of the resin liquid r dropped and supplied to the surface of the first guide roller 300 can be easily adjusted by the first position adjusting unit 500, the resin liquid r applied by the resin liquid application machine 100 is wide. Those having various viscosities are used. For this reason, the mechanism which heats the resin liquid r in the 1st storage part 400 is unnecessary.

  In addition, since the amount of the resin liquid r supplied to the sheet-like long base material F can be determined by the first position adjustment unit 500, the resin amount is once applied to the roller and then the doctor blade is used. There is no need to adjust. Therefore, the resin liquid coating machine 100 can reduce the contact of the resin liquid r to be applied to the outside air, and the adhesive is often applied in a space where dust management is not strictly performed such as outdoors. This is particularly useful when a resin composition is applied.

(1-2-4. Scraper)
As shown in FIG. 2, the first scraper 700 is disposed on the surface of the first guide roller 300 and on the downstream side from the supply port 430 and the outlet side of the first guide roller 300. That is, in the state where the sheet-like long base material F is disposed, the sheet-like long base material F is located on the outlet side of the sheet-like long base material F and below the long member.

  The first scraper 700 is provided with the same length as the width of the first guide roller 300 in the longitudinal direction (see arrow W) or longer than the width. When the resin liquid r is applied over the entire surface of the sheet-like long base material F, the length of the supply port 430 in the longitudinal direction (see arrow W) is formed wider than the width of the sheet-like long base material F. . Therefore, the resin liquid r adheres to the portions of the first guide roller 300 on both sides of the sheet-like long base material F in the longitudinal direction (see the arrow W). The adhered resin liquid r is scraped off by the first scraper 700. be able to.

(1-2-5. Leg part and first base roller support part)
The leg portion 120 is disposed below the main body portion 110 and supports the main body portion 110. The first base roller support portion 130 rotatably supports the first base roller R1 around which the sheet-like long base F is wound.

  FIG. 5 is a perspective view showing the vicinity of the first base roller support part 130. The first base roller support part 130 includes a bracket 131 and a first brake mechanism 132. The bracket 131 is fixed to the leg portion 120 so as to protrude toward the upstream side (see arrow X2). A recess 131 a is formed on the upper side of the bracket 131. An end R1e of the first base roller R1 is disposed in the recess 131a, and the recess 131a forms a bearing for the first base roller R1.

  The first brake mechanism 132 is a mechanism that brakes the rotation of the first base roller R <b> 1, and is provided on the bracket 131. The first brake mechanism 132 includes a through hole 131b formed in the bracket 131 and a screw member 133 inserted into the through hole 131b. The through-hole 131b is formed from the upstream end surface of the bracket 131 to the recess 131a along the transport direction X, and an opening is formed on the inner surface on the upstream side of the recess 131a. A screw shape is formed on the inner peripheral surface of the through hole 131b.

  The screw member 133 is inserted into the through hole 131b from the downstream side, and the screw shape of the surface of the shaft portion 133b of the screw member 133 and the screw shape of the inner peripheral surface of the through hole 131b are screwed together. An end 133c on the downstream side (see arrow X1) of the portion 133b is in contact with the end R1e of the first base roller R1. By rotating the head portion 133a of the screw member 133 and adjusting the pressing force of the end 133c against the end portion R1e, the sheet-like long base material F is driven by driving the first transport mechanism 200, the first guide roller 300, and the like. It is possible to adjust the braking force against the rotation of the first base roller R1 when being sent out. Thereby, the tensile stress applied to the sheet-like long base material F can be adjusted.

  The tensile stress applied to the sheet-like long base material F is adjusted to 1.4 kgf / m or more and 2.8 kgf / m or less per unit width, and more preferably 1.8 kgf / m or more and 2.4 kgf / m per unit width. Adjusted to: In FIG. 5, only one end side of the first base roller R1 is shown, but the other end side is similarly configured.

(1-3. Substrate combination mechanism)
Next, the substrate combination mechanism 103 will be described. The base material combination mechanism 103 is a mechanism for combining the mesh-like long base material M with the sheet-like long base material F.

  As shown in FIG. 2, the base material combination mechanism 103 includes a first roller 610, a second roller 620, a pair of support members 630, and a second base material roller support portion 640. As shown in FIG. 1A, the pair of support members 630 are rod-shaped members that face each other in the width direction of the sheet-like long base material F (see arrow W), and are between the first applicator 101 and the second applicator 102. Is arranged. The pair of support members 630 are fixed to the second applicator 102 as shown in FIG. 1C, and are provided to project upward from the first applicator 101 and the second applicator 102 as shown in FIG. ing.

  A second base material roller R2 around which the mesh-like long base material M is wound by the second base material roller support portion 640 is fixed to the upper ends of the pair of support members 630. As shown in FIGS. 1C and 2, the second base roller support portion 640 includes a bracket 641 fixed to the upper end of the support member 630 and a second brake mechanism 642. The bracket 641 is fixed to the upper end of the support member 630. The second brake mechanism 642 is a mechanism that is provided on the bracket 641 and brakes the rotation of the second base roller R2. A concave portion 641a is formed at the upper end of the bracket 641, and the end portion R2e of the second base roller R2 is disposed. The configuration of the second brake mechanism 642 is the same as the configuration of the first brake mechanism 132, and includes a through hole 641b (see FIG. 2) formed in the bracket 641 and a screw member 643 inserted into the through hole 641b. . The through hole 641b is formed from the upstream end surface of the bracket 641 to the recess 641a along the transport direction X, and an opening is formed on the upstream surface of the recess 641a. The through hole 641b has a screw shape on the inner peripheral surface.

An end 643c (see FIG. 2) on the downstream side (see arrow X1) of the shaft portion of the screw member 643 abuts on the end R2e of the second base roller R2. By rotating the head of the screw member 643 to adjust the pressing force against the end R2e of the second base roller R2, a mesh-like long base material is used by the second transport mechanism 202 and the second guide roller 302 described later. The braking force against the rotation of the second base roller R2 when M is sent out can be adjusted. Thereby, the tensile stress applied to the mesh-like long base material M can be adjusted.

  The tensile stress applied to the mesh-like long base material M is 0.8 kgf / m or more and 2.0 kgf / m or less per unit width. More preferably, the tensile stress 1 applied to the mesh-like long base material M is adjusted to 1.2 kgf / m or more and 1.6 kgf / m.8 kgf / m or more per unit width. In FIG. 2, only one end side of the second base roller R2 is shown, but the other end side is configured similarly.

As shown in FIG. 2, the second roller 620 is disposed below the first roller 610 and downstream of the first outlet roller 290 (see arrow X <b> 1).

  The mesh-like long base material M is drawn from the downstream side of the second base material roller R2 toward the upstream side of the first roller 610 (see arrow X2), and further from the upstream side of the second roller 620 to the lower side. Has been routed to. As a result, the mesh-like long base material M is arranged on the surface of the sheet-like long base material F that passes through the first outlet roller 290 and passes under the second roller 620, and is applied thereto. The sheet-like long base material F and the mesh-like long base material M are combined.

  For example, the mesh-like long base material M may be formed of a resin such as vinylon.

(1-4. Second coating machine)
The second applicator 102 is not provided with a pair of feed rollers 220 and rollers 230 as compared with the first applicator 101, but the other configuration is the same as that of the first applicator 101.

Second applicator 102 includes a main body 112 and a leg 122.
The main body 112 includes a second transport mechanism 202 (see FIG. 2), a second guide roller 302, a second storage unit 402, a second position adjustment unit 502, and a second scraper 702 (see FIG. 2). Contained.

  As shown in FIG. 2, the second transport mechanism 202 includes a second motor 212, a second outlet roller 292, and a motor gear, a guide roller gear, and an outlet roller gear (not shown).

  The second guide roller 302 and the second outlet roller 292 are arranged in this order from the upstream side, and both are pivotally supported by the main body frames 125 (see FIG. 1C) at both ends of the main body portion 112. As shown in FIG. 1C, a second drive unit 126 is connected to one side of the main body frame 125 (facing the conveyance direction and on the right hand side). Two motors 212 are accommodated.

  A rotation shaft of the second motor 212 protrudes from the second drive unit 126 in which the second motor 212 is accommodated into the one main body frame 125. In the one main body frame 125, the rotational driving force by the rotation shaft of the second motor 212 is transmitted to the shaft cores of the second guide roller 302 and the second outlet roller 292, so that the motor gear, the guide roller gear, and the outlet roller gear A gear train is configured.

  In addition, the 2nd guide roller 302, the 2nd storage part 402, the 2nd position adjustment part 502, and the 2nd scraper 702 in the 2nd applicator 102 are the 1st guide roller 300 of the 1st applicator 101, the 1st storage part, respectively. Since 400, the 1st position adjustment part 500, and the 1st scraper 700 have the same fundamental structure, detailed description is abbreviate | omitted and it demonstrates centering on difference.

  The second guide roller 302 is disposed below the second storage unit 402, and a sheet-like long base material is provided between the supply port 430 formed at the lower end of the second storage unit 402 and the second guide roller 302. F and the mesh-like long base material M pass through. That is, the sheet-like long base material F and the mesh-like long base material M are wound around the upper part of the second guide roller 302 in a state where the mesh-like long base material M is arranged on the upper side of the sheet-like long base material F. It has been applied. And when passing between the supply port 430 and the 2nd guide roller 302, the surface side (it arrange | positions in the sheet-like long base material F) of the mesh-like long base material M of the sheet-like long base material F is arrange | positioned The resin liquid r is supplied from the second reservoir 402 to the mesh-like long base material M).

  The positional relationship between the second guide roller 302 and the second storage unit 402 is the same as that of the first applicator 101, and the center of the opening width in the short direction (arrow X direction) of the supply port 430 is the second guide roller. It is disposed so as to be located on the right side (conveying direction side) of the shaft 302. Note that the distance between the center of the opening width of the supply port 430 and the axis of the second guide roller 302 may be the same as or different from that of the first coating machine 101.

  Further, the resin liquid r stored in the second storage unit 402 is the same as the resin liquid r stored in the first storage unit 401.

  Further, the difference between the rotation speed of the second guide roller 302 and the rotation speed of the first guide roller 300 is set within 5%. Further, the amount of the resin liquid r supplied from the supply port 430 of the first storage unit 400 is set to be larger than the amount of the resin liquid r supplied from the supply port 430 of the second storage unit 402. . This difference in supply amount is determined by using the first position adjusting unit 500 and the second position adjusting unit 502 to set the interval between the first storing unit 400 and the first guide roller 300 between the second storing unit 402 and the second guide roller 302. This can be realized by setting it larger than the interval. Further, the difference in the supply amount is the width in the short direction (arrow X direction) of the supply port 430 of the first storage unit 400 in the short direction (arrow X direction) of the supply port 430 of the second storage unit 402. It may be realized by making it longer than the width.

  Similar to the first scraper 700, the second scraper 702 is disposed on the outer peripheral surface of the second guide roller 302.

  In the second applicator 102, as shown in FIG. 2, the resin liquid r is applied from the second storage unit 402 onto the sheet-like long base material F in which the mesh-like long base material M is combined. The mesh-like long base material M and the sheet-like long base material F to which the resin liquid r is applied in the second coating machine 102 are discharged from the second outlet roller 292 as the composite base material S.

While operation | movement of the resin liquid coating device 100 of the said structure is demonstrated, an example of the manufacturing method of the composite base material of this invention is also described simultaneously. FIG. 6 is a flowchart showing the operation of the resin liquid coating machine 100.

  First, the first motor 210 and the second motor 212 are driven, and the first conveying mechanism 200, the second conveying mechanism 202, the first guide roller 300, and the second guide roller 302 move the sheet-like length from the first base roller R1. The long base material F is continuously sent out, and the mesh-like long base material M is continuously sent out from the second base material roller R2 (steps S10 and S20).

  Here, a tensile stress of 1.4 kgf / m or more and 2.8 kgf / m or less per unit width is applied to the sheet-like long base material F, and 0.8 kgf / unit per unit width is applied to the mesh-like long base material M. A tensile stress of m or more and 2.0 kgf / m or less is applied. Furthermore, the tensile stress applied to the sheet-like long base material F is 1.8 kgf / m or more and 2.4 kgf / m or less per unit width, and the tensile stress applied to the mesh-like long base material M is unit width. More preferably, it is 1.2 kgf / m or more and 1.6 kgf / m or less. The tensile stress on the sheet-like long base material F is set in the above range by adjusting the first brake mechanism 132, and the tensile stress on the mesh-like long base material M is adjusted by adjusting the second brake mechanism 642. The above range is set.

  Further, the difference between the rotation speed of the first guide roller 300 and the rotation speed of the second guide roller 302 is set within 5%.

  When the sheet-like long base material F unwound from the first base material roller R1 reaches between the first reservoir 400 and the first guide roller 300 via the roller 230 and the pair of feed rollers 220, As shown in step S <b> 30, the resin liquid r is supplied to the sheet-like long base material F from the supply port 430 of the first storage unit 400.

  Next, as shown in step S <b> 40, the mesh-like long base material M sent out by the second transport mechanism 202 of the second coating machine 102 is a resin of the sheet-like long base material F below the second roller 620. The liquid r is disposed on the coated surface. Specifically, the mesh-like long base material M is sent out from the second base material roller R2 by driving the second guide roller 302 and the second outlet roller 292 of the second coating machine 102, and the first roller 610 and the second roller The sheet-like long base material F is combined through the roller 620. Thereby, the mesh-like long base material M is bonded to the sheet-like long base material F by the resin liquid r applied to the sheet-like long base material F by the first coating machine 101.

  Next, as shown in step S <b> 50, when the sheet-like long base material F combined with the mesh-like long base material M reaches between the second storage unit 402 and the second guide roller 302, the sheet-like length The resin liquid r is supplied from the supply port 430 onto the mesh-like long base material M disposed on the long base material F. Here, the amount of the resin liquid r supplied from the supply port 430 of the first storage unit 400 of the first coating machine 101 is the resin liquid supplied from the supply port 430 of the second storage unit 402 of the second coating machine 102. It is set to be larger than the amount of r. The mesh-like long base material M is integrated by the sheet-like long base material F by further application of the resin liquid r by the second applicator 102.

  Next, the sheet-like long base material F and the mesh-like long base material M coated with the resin liquid r in the second applicator 102 are discharged out of the second applicator 102 through the second outlet roller 292. .

  The composite base material S by which the mesh-like long base material M was integrated with the sheet-like long base material F and the resin liquid was apply | coated is produced by the above. For this reason, the composite base material S in which the sheet-like long base material F and the mesh-like long base material M are combined can be attached to a concrete structure, thereby providing a weather resistance and anti-peeling function. .

<3. Features>
(3-1)
The manufacturing method of the composite base material S of this Embodiment is a manufacturing method of the composite base material which combined the sheet-like elongate base material F and the mesh-like elongate base material M, Comprising: Step S10 (sheet-like elongate shape) An example of a base material supply process), step S20 (an example of a mesh-like long base material supply process), step S30 (an example of a resin liquid application process), and step S40 (an example of a combination process) are provided. Step S10 (an example of a sheet-like long base material supplying step) supplies the sheet-like long base material F. Step S20 (an example of a mesh-like long base material supplying step) supplies the mesh-like long base material M. Step S30 (an example of a resin liquid application process) applies the resin liquid r to the sheet-like long base material F. Step S40 (an example of a combination process) combines the mesh-like long base material M with the sheet-like long base material F. In step S10 (an example of a sheet-like long base material supply process), step S30 (an example of a resin liquid application process) and step S40 (an example of a combination process), a sheet-like long base material F is applied to a unit of 1.4 kgf / unit width. A tensile stress of m to 2.8 kgf / m is applied, and in step S20 (an example of a mesh-like long base material supply process) and step S40 (an example of a combination process), a unit width is added to the mesh-like long base material M. A tensile stress of 0.8 kgf / m to 2.0 kgf / m is applied.

  Thereby, since the resin liquid r is already applied in a state where the mesh-like long base material M is combined with the sheet-like long base material F, two different base materials can be attached to the object at the same time. It becomes. For this reason, two base materials can be attached easily.

  Further, by applying the resin liquid r in two stages, the resin liquid r can be appropriately applied while integrating the sheet-like long base material F and the mesh-like long base material M.

  In addition, by setting the tensile stress to be applied to the sheet-like long base material F and the tensile stress to be applied to the mesh-like long base material M in a predetermined numerical range in this way, the composite is achieved while suppressing the generation of wrinkles. A substrate can be manufactured.

  Since the mesh-like long base material M is a vacant long base material, when a strong tensile stress is applied, the shape cannot be maintained, and the whole base material is distorted, causing warping and wrinkles. The quality may not be ensured. Moreover, when the tensile stress added to the mesh-like long base material M is high, deviation from the sheet-like long base material F occurs, and there is a possibility that uneven thickness of the adhesive may occur. Therefore, by making the tensile stress applied to the mesh-like long base material M smaller than that of the sheet-like long base material F, generation of wrinkles can be suppressed and the composite base material S having good quality can be manufactured.

<4. Other embodiments>
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of invention. In addition, the embodiments described in this specification can be arbitrarily combined.

(A)
In the above embodiment, in order to adjust the amount of the resin liquid r to be supplied to the first guide roller 300, the first position adjusting unit 500 adjusts the vertical position of the first storage unit 400 to supply the supply port 430. The space existing between the first guide roller 300 and the surface of the first guide roller 300 is adjusted. Further, in order to adjust the amount of the resin liquid r supplied to the second guide roller 302, the vertical position of the second reservoir 402 is adjusted by the second position adjusting unit 502, and the supply port 430 and the second guide are adjusted. The space existing between the surface of the roller 302 is adjusted.

  However, as long as the space between the supply port 430 and the guide rollers 300 and 302 can be adjusted, the present invention is not limited to the above-described mode, and the positional relationship between the guide roller 300 and the supply port 430 is relatively variable. I just need it.

  For example, if it demonstrates using the 1st coating device 101, either the 1st guide roller 300 and the 1st storage part 400 may be comprised so that a movement is possible. Further, the first guide roller 300 and the first storage unit 400 may be configured such that the positional relationship in the vertical direction is variable, or configured so that the positional relationship in the horizontal direction is variable. Alternatively, the positional relationship in both the vertical direction and the horizontal direction may be variable.

  Specifically, as a modification, it is possible to configure the shaft core of the first guide roller 300 to be movable up and down. That is, the distance between the supply port 430 and the first guide roller 300 is also adjusted by changing the vertical position on the first guide roller 300 side, and supplied to the sheet-like long base material F on the first guide roller 300. The amount of resin to be made can be easily determined. The storage unit in this case may be movable up and down by the first position adjustment unit 500 like the illustrated first storage unit 400, or the vertical position is fixed without having the first position adjustment unit 500. It may be.

Moreover, it is good also as a structure which can move the position of the 1st storage part 400 to a horizontal direction (left-right direction) as another modification. 7 shows, for example, that the first reservoir 400 is moved from the position of FIG. 3 in the direction of arrow T (that is, the horizontal direction opposite to the rotation of the guide roller 300), and the center of the supply port 430 in the horizontal direction. A state in which the position coincides with the central axis Q2 of the first guide roller 300 is shown. In this case, the distance _{L E1} of the supply port 430 inlet side between the first guide roller 300 of the first reservoir 400 (corresponding to the distance _{L E} in FIG. 3) is expanded to the distance _{L E2,} the outlet The distance L _D1 (corresponding to the distance L _D in FIG. 3) is reduced to the distance L _D2 . The distance L _E2 and the distance L _D2 are equal.

  Furthermore, the first reservoir 400 may be moved in the direction of the arrow, and the central position of the supply port 430 in the horizontal direction may be moved to the left side (inlet side) of the central axis Q2 of the first guide roller 300.

  Note that these modified examples are the same between the supply port 430 of the second coating machine 102 and the second guide roller 302.

(B)
The position of the 1st storage part 400 as described in the said modification (A) may not be a structure which can move, and the center position (Q1 of FIG. 3) of the supply port 430 of the 1st storage part 400 in a horizontal direction May be fixed in a state of being aligned with the central axis Q2 of the first guide roller 300. Similarly, the position of the second storage unit 402 is not movable and is fixed in a state where the central position of the supply port 430 of the second storage unit 402 in the horizontal direction coincides with the central axis of the second guide roller 302. May be.

  In addition, not only in the matched state, but in the opposite direction to the above embodiment, the supply port 430 in the horizontal direction is fixed in a state where the central position is located on the left side (inlet side) of the central axis Q2 of the first guide roller 300. May be. Similarly, the position of the second reservoir 402 is not movable, and the central position of the supply port 430 in the horizontal direction of the second reservoir 402 is on the left side (inlet side) of the center axis of the second guide roller 302. It may be fixed in a positioned state.

(C)
In the said embodiment, although the supply port 430 of the 1st storage part 400 and the 2nd storage part 402 is horizontal, you may incline. FIG. 8 is a view showing the first storage unit 403 having the inclined supply port 433.

  In FIG. 8, the axis of the first guide roller 300 is aligned with the center in the horizontal direction of the supply port 433 of the first reservoir 403.

The supply port 433 of the first reservoir 403 has an opening width that extends from the inlet side to the outlet side of the first guide roller 300 (in the direction of the arrow X). The supply port 433 is configured to have a shape in which the end on the outlet side becomes higher. Therefore, as shown in FIG. 8, when the shaft center of the guide roller 300 is positioned vertically below the center in the horizontal direction of the supply port 433, the distance between the supply port 433 and the first guide roller 300 is distance toward the distance L _D of the outlet side is larger than L _E. In addition, the supply port 430 of the 2nd storage part 402 may be formed inclining.

  Moreover, the 1st storage part 403 may be comprised so that position adjustment is possible not only in an up-down direction (refer FIG. 3) but a horizontal direction or both the horizontal direction and an up-down direction.

(D)
The 1st storage part 400 and the 2nd storage part 402 of the said embodiment may be comprised so that attachment or detachment is possible. For example, in the 1st storage part 400, the 1st storage part 400 is comprised by removing the adjustment screw 520 and releasing the connection of the holding | maintenance part 450 of the 1st storage part 400, and the fixing | fixed part 510 of the main-body part 110. Can be removed from the main body 110.

  When the 1st storage part 400 is comprised so that attachment or detachment is possible, it can change to another storage part of a different structure, for example. Examples of different structures include a structure that changes the range of the supply amount of the resin liquid r and a structure that changes the coating width of the resin liquid r. As a structure for changing the range of the supply amount of the resin liquid r, for example, a structure in which the protruding amount of the supply port 430 (specifically, the length from the holding portion 450 to the opening end of the supply port 430) is different, and A structure in which the opening width in the short direction of the supply port 430 is different can be given. Examples of the structure for changing the application width of the resin liquid r include structures in which the opening length of the supply port 430 in the longitudinal direction is different. Such a configuration makes it easier to cope with the viscosity of the resin liquid r, makes it easier to adjust the application amount of the resin liquid r, and / or easily changes the application width of the resin liquid r. This is preferable.

  In addition, it is preferable that the first storage unit 400 and the second storage unit 402 are configured to be detachable from the standpoint of facilitating cleaning of each member.

(E)
In the first storage unit 400 and the second storage unit 402 of the above embodiment, since the length in the longitudinal direction (arrow W direction) is fixed, the coating width is constant, but the coating width is configured to be variable. It may be.

  In addition, although demonstrated as a modification of the 1st coating device 101, you may apply to the 2nd coating device 102. FIG.

  FIG. 9 is a perspective view showing a schematic appearance of a first applicator 104 which is a modification of the first applicator 101. FIG. 10 is a partially enlarged view of the resin liquid applicator shown in FIG. The first applicator 104 shown in FIGS. 9 and 10 is the same as the first applicator 101 except that the first reservoir 404 includes a partition 460.

  The partition part 460 partitions the longitudinal direction inside the 1st storage part 404, as shown in FIG. Since the resin liquid r is held only on one surface side of the partition part 460, the application width of the resin liquid r by the first storage part 404 is determined.

  The partition part 460 includes a partition plate 461 and a fixing part 465 as shown in FIG. The partition plate 461 is a plate member having a planar shape corresponding to the cross-sectional shape of the internal space of the first storage unit 400. When the partition plate 461 is fitted into the internal space of the first storage unit 400, the side end surface 462 closely contacts the inner wall of the first storage unit 404, and the resin liquid r moves from one side to the other side (see FIG. 9), the resin liquid r is held only on one surface side. The fixing portion 465 is a member configured to fix the partition plate 461 to the first storage portion 404. In the present embodiment, the fixing portion 465 extends from the partition plate 461 in a shape that fits to the upper edge portion of the first storage portion 404 and is fixed by a fixing tool such as a screw 466 on the outer surface side of the upper edge portion. Fixed. Thereby, the partition part 460 is positioned in the longitudinal direction (arrow W direction) of the first storage part 404 (also referred to as the width direction of the sheet-like long base material F). The fixing position in the longitudinal direction by the fixing portion 465 can be designed to be plural or arbitrary. Thereby, the position of the partition part 460 in the longitudinal direction of the first storage part 404 can be variously changed.

  For this reason, the application width | variety of the resin liquid r can be changed, without performing replacement of the storage part as mentioned above. Therefore, the 1st coating device 104 is applicable also to the sheet-like long base material Fb (refer FIG. 9) which has the width | variety of less than the full length (of the supply port 430) of the 1st storage part 404. FIG.

  In the illustrated embodiment, the first applicator 104 is provided with one partition 460, but is not limited to this embodiment. For example, two partition portions 460 may be provided, and the resin liquid r may be held between the two partition portions 460.

  The method for producing a composite base material of the present invention has an effect capable of producing a composite base material capable of easily attaching two base materials to an object, and has two long bases. It is useful as application of resin to the material.
