Abstract

An object is to provide a method of producing a sheet joined body and an apparatus for producing a sheet joined body, which are capable of preventing or reducing breakage of a resin sheet member in a subsequent treatment section, such as impregnation of a joined portion of resin sheet members with chemical or stretching of a resin sheet member, while, at the same time, joining resin sheet members together without the necessity to stop transferring of resin sheet members to the treatment section when in joining operation. A method of producing a sheet joined body, in which a first one of two or more band-shaped resin sheet members is first transferred to a treatment section and then is joined to a following second one to produce a sheet joined body, includes: a first step of nipping a leading end of the second resin sheet member; a second step of coating the leading end nipped in the first step with a light absorber; a third step of transferring the first sheet resin sheet member via a sheet reserving part, which reserves the first resin sheet member transferred from the upstream side and transfers the reserved first resin sheet member to the downstream side so that the inputting speed of the first resin sheet member is differentiated from the outputting speed of the first resin sheet member, thereby allowing the first sheet member to be continuously transferred on the downstream side of the sheet reserving part and to be intermittently transferred while being nipped on the upstream side of the reserving part; a fourth step of cutting the first resin sheet member nipped in the third step so as to have the nipped portion becoming as a tail end of the first resin sheet member; a fifth step of overlapping the leading end to the tail end with the light absorber therebetween; a sixth step of joining the overlapped leading and tail ends together by laser welding while pressing them; and a seventh step of releasing the leading and tail ends from the pressed conditions and nipped conditions, thereby allowing the second resin sheet member to be transferred to the treatment section subsequent to the first resin sheet member.

The method for producing such a polarizing film employs a method in which a strip-shaped polyvinyl alcohol-based resin (pvA) thin resin sheet member as a preform material is fed from a raw material wound into a roll. The film (resin sheet member) restricts the movement path of the seed material film, and leads to a device having a plurality of liquid baths for guiding the skin film (four), which is called an extension, and in other words, the following method can be used. After the transfer film is moved in the longitudinal direction, and continuously immersed in the swelling bath or the dye bath, the preform is held by the above-mentioned roller at the front and rear positions, and the tension is applied between the two. In the method for manufacturing such a polarizing film, the new blank material film is re-wound on a roller or the like every time the embryo material is replaced, and then placed in the device is complicated and 'good time' The end portion of the Sakizaki film is joined from the next embryo. The front end is made to connect the scales to the S-shaped joint body. Then, the two seed material films are sequentially processed into polarized light. 201213104 Manufacture of such sheet-like joint body The method is known to employ a bonding means such as an adhesive tape or an adhesive, a suture bonding means by a rivet or a wire, or a heat fusion bonding means by a heat sealer or the like. However, in the above methods, the following problems are respectively caused. The problem of the subsequent bonding of the adhesive tape or the adhesive is such that the raw material film is immersed in the expansion bath, the dye bath, or the like, and the chemical solution is dissolved in the chemical solution due to the composition of the adhesive agent, and may be formed as The main reason why the foreign matter adheres to the product. In addition, since the adhesive is dissolved in the chemical solution or expanded by the components of the chemical solution, the joint strength is lowered, and in the stretching step, the joint portion is broken before the desired stretch ratio is reached. After that. The problem of the stitching joint by the rivet or the thread In this method, since the preform material film is passed through to allow the rivet or the thread to pass through, the tension is applied to the joint portion, and the rupture is started from the hole. In order to prevent this, the number of holes is reduced to ensure that the interval between the holes is wide, and when the tension is applied to the garden, wrinkles are likely to occur, and unevenness of elongation occurs. • The problem of heat fusion bonding by a heat sealer or the like can be achieved by the heat sealer as shown in the following patent documents 2 and the like. Means. σ This method has a lower enthalpy of contamination than the subsequent bonding, and does not need to be provided as a seam. However, in the heat sealer, the welded region and its periphery are deformed by the heat received during the welding, and the hardened state is inclined to the state of 201213104. Therefore, when extending, when the tension is applied through the welded region, it is easy to concentrate on the hardened portion and the ordinary state to generate the money, and the region is extremely extended before the whole reaches the stretch ratio of the period. Hey. Therefore, when the elongation of the high stretch ratio is to be carried out, there is a possibility that the graft of the preform material is broken at the joint portion. PRIOR ART DOCUMENT PATENT DOCUMENT Patent Document 1 Patent Publication No. 2007-171897 Patent Document 2 曰 Patent Publication No. 2010-8509 No. L. Summary of the Invention The object to be solved by the invention is to impart a high polarization function to a polarizing film. In general, it is required to apply an extension of 5.25 times or more. When a preform material made of a polyvinyl alcohol resin is used as a method for producing a conventional sheet-like joined body as described above, the joint portion cannot withstand an extension load of 5·25 times or more. In the case of the occurrence of a fracture, the countermeasure is as follows. The countermeasure is to change the stretching ratio during the passage of the connecting portion to less than 5.25 times, thereby avoiding breakage. However, when the countermeasures are avoided as described above, the work is complicated due to the change of settings. Further, since the stretching ratio before and after the connecting portion does not form the desired magnification (5.25 times or more), it cannot be used as a product, and there is a possibility of material loss. That is, in the conventional method for producing a sheet-like bonded body, when a polarizing film is produced, there is a problem that it is difficult to produce a polarizing thin film 201213104 having a high polarizing function with good efficiency. On the other hand, as described above, when the end portion of the leading blank material film is joined to the front end portion of the next blank material roll, it is possible to prevent the new blank material film from being wound on the roll or the like every time the original material roll is replaced. And then placed in the cumbersome device. However, in order to join the tip end portion and the tip end portion to temporarily release the blank material film, when the transfer of the seed material film is stopped during the stop period, since the extension is stopped during this period, the conventional shape is The manufacturing method of the joined body also has a problem that the manufacturing efficiency is lowered. The present invention has been made in view of the above problems, and an object thereof is to provide a process for suppressing breakage of a treatment region in a portion after penetration or extension of a chemical solution, and to carry out the transfer of the resin sheet member to the treatment region at the time of joining. A method of manufacturing a sheet-like joined body of a member, and a manufacturing apparatus of a #-shaped joined body. A method for producing a sheet-like joined body according to the present invention for solving the above-mentioned problems is a method of manufacturing a sheet-like joined body in which two or more read resin sheet members are transferred to a processing region, and a second resin sheet member The resin sheet member is joined to form a sheet-like joined body, and is characterized in that it includes a first step, a second step, a third step, a fourth step, a fifth step, a sixth step, and a seventh step, and the first step is maintained The second resin sheet member has a front end portion; the second step applies a light absorbing agent to the front end portion held in the first step, and the third step is performed by the following sheet storage portion The first resin X member is conveyed to the processing region and can be placed on the downstream side of the sheet storage portion, and the above-described first step is continued! The conveyance of the sheet member is performed on the upstream side to stop the conveyance of the first sheet member, and 201213104 simultaneously holds the first resin sheet member, and the sheet storage portion is configured to store the first resin carried in from the upstream side. In the sheet member, the storage of the first resin sheet member is carried out to the downstream side, whereby the loading speed of the second resin sheet member is different from the carrying speed; and the fourth step is performed in the third step. The first resin sheet member held is cut into a portion to be held to constitute a distal end portion; and in the fifth step, the front end portion and the distal end portion are overlapped with the light absorber; the sixth step is The front end portion and the end portion portion-surface which have been superposed in the fifth step are pressurized, and the surface is removed, whereby the jointer is removed; the seventh step is to release the front end portion and the end portion The pressurization is carried out with the front end portion and the end portion, and then the second resin sheet member is attached to the first grease sheet and then transported to the processing region. By this, the first resin sheet of the two or more strip-shaped resin sheets is joined by laser welding, and the end portion of the first resin sheet member and the second end portion of the succeeding second resin sheet member are combined with the first resin sheet. When the second resin sheet member joined by the member is attached to the first tree (four) member and then processed, for example, when it is immersed in the test, it is used in comparison with the use of the first or the like, and then, when the bonding is performed, the contamination of the chemical solution or the strength of the chemical solution can be suppressed. Reduced by the liquid. In the first laser welding, when the first and second members are continuously stretched, when the joint portion is not properly connected, the joint may be prevented from being broken, and the joint may be prevented. The extension is performed continuously under the condition of no limb extension, and the extension is continuously applied. When the first resin sheet member is transported by the sheet I, the first resin sheet member is processed while the first resin sheet is held. Area transfer. In the meantime, it is possible to prevent the joint portion from being broken at the processing region after the penetration or extension of the chemical liquid, and to join the resin sheet member without stopping the conveyance of the resin sheet member to the processing region. Further, in the method for producing a sheet-like joined body according to the present invention, it is preferable to include the eighth step of winding the second resin sheet member into the first resin sheet member to be cut in the fourth step. Useless part, and recycle the useless part. Thereby, it is easy to remove the useless portion. Further, in the method for producing a sheet-like joined body of the present invention, the resin sheet member is preferably a single layer of a thermoplastic resin film. Thereby, it is easy to produce a sheet-like joined body. Further, in the method of producing a sheet-like joined body of the present invention, the resin sheet member is preferably a polyvinyl alcohol-based resin film for producing a polarizing film. Thereby, when the stretching process is performed in the subsequent stage, since the film can be stretched without breaking, the polarizing film can be imparted with a high polarizing function. Further, since the stretching process can be continuously performed without changing the stretching ratio, the occurrence of material loss can be avoided. Therefore, a polarizing film having a high polarizing function can be manufactured with good efficiency. Further, in the apparatus for manufacturing a sheet-like joined body of the present invention, two or more strip-shaped resin sheet member sheets are first joined to the second resin sheet member of the processing region to form a sheet shape. The feature of the bonded body includes a sheet storage portion, a first holding portion, a cutting portion, a second holding portion, an F cloth portion, an arrangement adjusting portion, a pressurizing portion, and a laser light irradiation portion, and the sheet stores a P-series structure. The first resin sheet member carried in from the upstream side is stored, and the first sheet member stored in the jin is carried out to the downstream side, whereby the moving speed and the carrying-out speed of the first resin sheet member of the 201213104 are different. On the downstream side, the first resin sheet is conveyed to the processing region, and the first resin sheet conveyer is stopped on the upstream side; the third holding portion is disposed in the sheet storage. Further, the upstream side is provided to hold the second resin sheet member in association with the conveyance stop of the first resin sheet member, and the cutting portion is configured to cut the first resin sheet member to be held by the second holding portion. Partial composition The second holding portion holds the end portion of the second resin sheet member; the coating portion applies a light absorbing agent to the end portion held by the second holding portion; the arrangement adjusting portion Disposing the front end portion and the end portion portion such that the front material and the end portion are overlapped with the light absorber; and the pressing portion presses the overlapping portion of the front end portion end portion; The laser beam irradiation unit irradiates the laser beam to the overlapping portion that is pressurized by the pressing portion, and the front end portion and the end portion are joined by laser splicing; The manufacturing apparatus of the joint body is configured to release the force of the front end portion and the end portion of the pressing portion by the description. The second resin sheet member is attached to the first resin sheet member and then conveyed to the processing region after the pressure and the end portion and the end portion are held. By this, the end portion of the first resin sheet member which is preceded by the two or more strip-shaped resin sheets is joined by laser welding, and the first resin sheet member is joined to the first resin sheet member.

When two or more pieces of the seed material film 1 joined by the bonding apparatus 100 have a thermoplastic resin layer on the surface to be joined to each other, they may be formed of a single layer of a thermoplastic resin, or may be formed by laminating a thermoplastic resin layer and another resin layer. The qualifier is preferably formed of a single layer of a thermoplastic resin. Thereby, it is easy to produce a sheet-like joined body. Further, such a resin sheet member is generally composed of thermoplastic resins of the same kind, and the present invention is not limited to the same type, and may be of different types as long as they are mutually heat-meltable. Such a thermoplastic resin may, for example, be polycarbonate, polyvinyl alcohol, polyethylene, 13 201213104 polypropylene, polyethylene terephthalate, polyethylene gas, thermoplastic polyimide, cellulose triacetate, polymethyl. Acrylic acid, cycloolefin polymer, decene, polyoxymethylene ether, polyether ether ketone, polyether quinone imine, polyamidoximine, polybutene, polyamine phthalate, polyphenylene Ethylene, polydecylpentene, polydecylamine, polyacetal, polybutylene terephthalate, ethylene vinyl acetate, and the like are exemplified. Further, it is considered that the resin sheet is conveyed in a roll-to-roll manner, and the thickness thereof is preferably 1 μm or more and more than 2 mm or less in terms of a claw or more, and preferably 2 Å or less. Further, the 'resin sheet member is preferably a polyvinyl alcohol-based resin film for producing a polarizing film, that is, a film made of a polyethylene glycol-based polymer resin material, whereby the film may be formed without stretching in the subsequent stage. Extended, it can be given a high polarizing function of the polarizing film. Specifically, the polyvinyl alcohol-based resin thin film may be a polyvinyl alcohol film, a partially saponified polyvinyl alcohol thin film, or a dehydrated film of polyvinyl alcohol. The polymerization degree of the polymer which is a material for forming the polyvinyl alcohol-based resin film is generally 500 to 10,000, preferably in the range of 1,000 to 6,000, and in the range of 1,40 to 4, Better. Further, in the case of partially saponifying a polyvinyl alcohol film, the degree of saponification is preferably 75 mol% or more, preferably 98 mol% or more, and 98.3% to 99.8% from the viewpoint of solubility in water. The range is better. The joining device 100 includes a first sending portion (feeding portion) 21, a second holding portion 22, a cutting portion 23, a second feeding portion 24, a second holding portion 25, a table %, a laser light irradiation portion 27, and a pressurizing portion. 28. The coating unit 29, the arrangement adjustment unit 31, and the 201213104 (sheet storage unit) 32 are stored. The first delivery portion 21 can rotate the old blank material film 1& which is wound in a roll shape in the opposite direction to the positive direction and the winding direction, and can rotate the positive direction to feed the old blank material film la. The first delivery portion 21 can be formed by a roller member that is provided with a hollow portion of the wound old blank material film la. The first holding portion 22 has a flat upper surface portion that is disposed below the old blank material film ia that is sent from the first delivery portion 21. Further, a plurality of holes are formed in the upper surface portion, and the ejector member is not shown, and the old blank material film la is sucked and held on the upper surface portion. Then, when the delivery of the old seed material film la (the conveyance on the upstream side of the accumulator 32) is stopped, the first suction member is actuated to keep the old seed material film 1& 1 holding portion 22. The cutting portion 23 is formed by cutting the old blank material film 13, and is formed by the cutting tool 23 & and its receiving portion 23b. The cutting portion 23 is on the upstream side (the right side of the first drawing) of the portion of the old blank material film la held by the first holding portion 22, and is overlapped with the end portion 1b of the new preform material film 1b described later. Cut it off after serving. In this way, the cutting portion 23 is cut, and the old blank material film la can form the end portion laa of the old blank material film la that has been transported to the processing step for processing, and the unnecessary portion that is not processed (see Fig. 6). The second delivery portion 24 can rotate the new blank material film ib wound in a roll shape in the forward direction in which it is fed out and in the opposite direction of the winding, and rotate it in the forward direction to feed the new blank material film lb. The second delivery portion 24 can be formed by a roller member that is provided with a hollow portion of the wound new blank material film lb. The second holding portion 25 has a flat upper surface portion which is disposed below the thinning of the new blank material sent from the #24 201213104 2 delivery #24. Further, a plurality of holes are formed in the upper surface portion, and a second suction member (not shown) attracts a new metal material phase to the upper surface portion for holding. When the Uba overlaps the second holding portion and the surface of the table to be described later, the new raw material (4) 1b is stopped and the second suction member is actuated. The W end portion 1ba can be held in the second holding portion 25. The first delivery portion 21 and the second delivery portion 24 are provided in the g-position variable portion 41 that can be rotated to replace the positions. After the new and old blank material films U, lb are joined, the configuration of the variable portion 41 is rotated, and the new blank material film lb is disposed at the position of the old embryo material_la (the upper one), and at this position, the new seed material film is formed. 1b is sequentially enemies. At this time, the old blank material film 13 攸 configuration variable portion 41 disposed underneath can be removed from the newly installed new germ material film la under the cover 26_ with a flat upper surface. It is disposed on the downstream side (the right side of the figure) of the second holding portion. The material of the table 26 can be made of metal, ceramics, rubber, etc. Among these, it is preferable to use rubber as the material of the table 26. Therefore, as will be described later, the portion of the pressing portion 28 that overlaps the end (4) of the thin portion of the old blank material with the end portion 1ba of the new blank material film lb In the heart of the pressurizing stage, a large area can be uniformly pressurized. Therefore, a good bonding state can be obtained in the overlapping portion by the laser light to be described later. Further, the end portion laa is joined to the front end portion Iba. After that, in order to improve the peelability of the end portion (8) or to improve the heat resistance, the rubber surface may be subjected to surface treatment or a rubber surface area layer resin member. The laser light irradiation unit 27 has a laser light source and is disposed at the stage. "

Further, the pressurizing portion 28 is disposed above the table 26 and is disposed below the laser light irradiating portion 27 so as to be movable in the vertical direction. Further, it is configured such that the end portion laa of the preceding blank material film la and the front end portion lba of the new germicidal film film joined thereto are superposed on the table 26, and the overlapping portion is added When the pressing portion 28 is pressurized, the laser beam R is irradiated from the laser beam irradiation portion 27, whereby the interface portion between the beam end portion laa and the tip end portion 1b is heated and melted and welded, and the both are joined. Further, the pressurizing portion 28 is formed of a transparent member having excellent transparency of the laser light R. The type of the above-mentioned laser light source is not particularly limited, and the laser light system used is responsible for the following functions, and the above-mentioned functions are applied to the interface of the new and old blank material films in the portions of the new and old blank material films la and ib. It is absorbed by the light absorbing agent disposed on the new seed material film 1 to be heated, and it is preferable to have a wavelength at which the absorption sensitivity of the light absorbing agent used is high. Specifically, the type of laser light may be a semiconductor laser having a wavelength of a visible light region or an infrared region, a solid laser, a femtosecond laser, a picosecond laser, a YAG laser, or the like, and a c〇2 laser. Wait for a gas laser. Among them, a semiconductor laser or a fiber laser which is easy to obtain a low-cost and uniform laser beam in the plane is preferable. In order to avoid the decomposition of the seed material film and promote the melting, the cw laser of the continuous wave is better than the pulsed laser which can be input into the instantaneous high energy. The output (power) of the laser light, the beam size and shape, the number of irradiations, and the broom speed, etc., as long as the so-called optical characteristics of the light absorption rate of the target blank film and the light absorbing agent or the polymerization of the constituent blank film The difference between the melting point of the material and the so-called thermal characteristics of the glass transition temperature (Tg) is appropriate. The current portion of the laser light can be used to illuminate the portion of the laser light to obtain the polytetrazide (tetra) grease. For a stable joint, the power of the irradiated laser light is preferably in the range of 200 W/cm 2 to 10,000 W/cm 2 and preferably in the range of 300 W/cm 2 to 5,000 W/cm 2 , more preferably l,000 W/cm 2 to 3,000 W/ It is especially good in the range of cm2. Further, it is preferable that the above-mentioned laser light source irradiates the laser beam with a spot diameter (irradiation width) of a predetermined size at the interface between the new and old blank material sheets. The irradiation spot diameter (irradiation width) is preferably at least half or more of the stacking width of the new and old blank material films la and lb at a power satisfying the above-described irradiation laser power density. If it is less than one-half of the overlap width, the unjoined portion of the superposed one portion is large, and after the joining, the flapping is performed at the time of conveyance, and the good conveyability is hindered. Further, when laser light is irradiated with a width of three times or more, although it does not affect the extension characteristics and the elongation characteristics, it is not preferable from the viewpoint of energy use efficiency. It is preferably equal to or greater than the same value as the overlap width, and is twice or less. Further, the overlap width of the new and old blank material films la and lb is 〇.imm or more, preferably less than 10.0 mm, and more preferably 0.5 mm or more and less than 5 mm. This is because, for the following reasons, if the overlap width is less than 0.1 mm, it is difficult to overlap the blank material 1 having a large width with good precision, and when it is 10.0 mm or more, to prevent In the formation of the joint portion, it is necessary to irradiate the laser light with a width of 10.0 mm or more, so that the necessary energy is increased, which is not preferable from the viewpoint of energy saving. In addition, the cumulative exposure of laser light ranges from 5 J/cm 2 to 400 J/cm 2 .
