Description

  The present invention relates to a method for producing a hollow fiber membrane module, a laminate production apparatus, and a hollow fiber membrane module production apparatus.

  The hollow fiber membrane module used for the production of aseptic water, drinking water, highly pure water, etc., has both ends of a laminate in which a plurality of hollow fiber membrane sheet-like materials obtained by arranging a plurality of hollow fiber membranes in a sheet shape are laminated. There is known a hollow fiber membrane module in which a water collecting pipe is provided in each part (Patent Document 1).

As a manufacturing method of such a hollow fiber membrane module, the following method is mentioned, for example.
One hollow fiber membrane sheet is placed on a flat surface, and an adhesive is applied on one end in the length direction of the hollow fiber membrane sheet. Next, another hollow fiber membrane sheet is stacked on the hollow fiber membrane sheet to which the adhesive is applied so that the end faces are aligned, and the ends are bonded and fixed. Such application and lamination of the adhesive to the end are repeated. Thereby, the laminated body by which the one end parts of the length direction of each hollow fiber membrane sheet-like object were adhere | attached and fixed in the state in which the end surfaces of each other were gathered is obtained. Next, also on the other end side in the length direction of the laminate, an adhesive is applied to the end of one hollow fiber membrane sheet, and the adjacent hollow fiber membrane sheets are aligned so that the end surfaces thereof are aligned. Repeat the operation of adhering and fixing the ends of the objects. Thereby, the laminated body by which the both ends of the length direction of each hollow fiber membrane sheet-like material were adhere | attached and fixed in the state in which the mutual end surface was in order is obtained.
Next, one end of the laminate in the length direction is inserted into the water collecting pipe, and a liquid potting resin (potting liquid) is injected and cured, and the end is liquid-tightly fixed in the water collecting pipe. Similarly, the other end portion of the laminated body is liquid-tightly fixed in the water collecting pipe to obtain a hollow fiber membrane module.

  However, in the manufacturing method described above, the more the number of hollow fiber membrane sheet materials to be laminated, the more complicated the operation of bonding and fixing the end portions thereof. Moreover, when working alone, the work efficiency is poor because the ends of the hollow fiber membrane sheet-like materials must be bonded and fixed one by one as described above. In addition, because the operator makes a difference in how the end surfaces of the hollow fiber membrane sheet-like materials in the laminate are aligned, it is difficult to stably manufacture a hollow fiber membrane module of equivalent quality. On the other hand, when trying to automate the process of obtaining a laminate, in addition to the means for laminating each hollow fiber membrane sheet, the means for applying an adhesive and the position of the end face of each hollow fiber membrane sheet are grasped. This requires a camera, sensor, etc., which makes the mechanism complicated and increases the cost.

  The method for producing a hollow fiber membrane module of the present invention includes a laminate in which a plurality of hollow fiber membrane sheets in which a plurality of hollow fiber membranes are arranged in a sheet shape are laminated, and the length of the hollow fiber membrane in the laminate. It is a method of manufacturing a hollow fiber membrane module comprising a water collecting pipe fixed to an end portion in the vertical direction.

[Hollow fiber membrane module]
Hereinafter, an example of the hollow fiber membrane module manufactured with the manufacturing method of this invention is shown and demonstrated.
The hollow fiber membrane module 1 of this embodiment is, as shown in FIGS. 1 to 4, a laminate 2 in which four hollow fiber membrane sheets 10 are laminated, and the length of the hollow fiber membrane 16 in the laminate 2. And a pair of long water collecting pipes 12a and 12b attached to both ends 2a and 2b in the direction. The ends 2a and 2b of the laminate 2 are fixed to the water collecting pipes 12a and 12b in a liquid-tight manner by the potting part 14 made of a cured product of a fixing potting resin while being inserted into the water collecting pipes 12a and 12b, respectively. ing.

The number of hollow fiber membrane sheets in the laminate is not limited to 4 and may be 3 or less, or 5 or more.
In the hollow fiber membrane sheet 10, a plurality of hollow fiber membranes 16 are aligned in a sheet shape so that they are parallel to each other, and both open end faces 16 a in the length direction of each hollow fiber membrane 16 are open. In this state, they are fixed to each other.

  Examples of the material of the hollow fiber membrane include polysulfone resins, polyacrylonitrile, cellulose derivatives, polyolefins such as polyethylene and polypropylene, fluorine resins such as polyvinylidene fluoride (PVDF) and polytetrafluoroethylene, polyamide, polyester, and polymethacrylate. And polyacrylate. Moreover, you may use what introduce | transduced the substituent into some of these resin. The material of the hollow fiber membrane may be one type or two or more types.

  In the hollow fiber membrane sheet 10, a band-shaped first width of a certain width extending in a direction orthogonal to the length direction of the hollow fiber membrane 16 at each of both end portions 11 a and 11 b in the length direction. A first binding portion 18a and a second binding portion 18b are provided. The plurality of hollow fiber membranes 16 are fixed to each other by the first binding portion 18a and the second binding portion 18b.

  In the portion of the hollow fiber membrane sheet 10 where the first binding portion 18a and the second binding portion 18b are provided, the distance between the adjacent hollow fiber membranes 16 is preferably 0 to 1 mm. If the distance between the adjacent hollow fiber membranes 16 is within the above range, the amount of the bundling portion used with respect to the number of hollow fiber membranes can be suppressed and the cost can be reduced while securing an effective membrane area.

The 1st binding part 18a is each provided in both the edge parts 11a and 11b of the length direction of the hollow fiber membrane 16 in the hollow fiber membrane sheet-like article 10. FIG. As shown in FIG. 4, the first binding portion 18 a is formed so as to fill the periphery of each hollow fiber membrane 16 and binds the hollow fiber membranes 16.
The 1st binding part 18a is the state inserted in the water collection pipes 12a and 12b. In this example, the opening end face 16a of the hollow fiber membrane 16 and the side end face on the opening end face 16a side of the first binding portion 18a are flush with each other. By providing the first binding portion 18a in this way, it is easy to suppress a decrease in the effective membrane area.

The second binding portion 18b is provided in the length direction in the vicinity of the end portions 11a and 11b of the hollow fiber membrane sheet 10 so as to be separated from the first binding portion 18a by the distance L2 in the center. The 2nd binding part 18b is located in the part exposed from the water collection pipes 12a and 12b in the hollow fiber membrane sheet-like thing 10. FIG. Similarly to the first binding portion 18a, the second binding portion 18b is formed so as to fill the periphery of each hollow fiber membrane 16, and binds the hollow fiber membranes 16 together.
The distance L2 can be set as appropriate, and is preferably 8 to 50 mm.

  The width L1 of the first binding portion 18a and the width L3 of the second binding portion 18b are each preferably 3 to 30 mm. If the width L1 and the width L3 are equal to or greater than the lower limit value, sufficient binding strength can be easily obtained. If the width L1 and the width L3 are equal to or less than the upper limit values, it is easy to suppress a decrease in film area. The width L1 and the width L3 may be the same or different.

  The distance t1 between the surface 18c in the thickness direction of the first binding portion 18a and the second binding portion 18b and the surface of the hollow fiber membrane 16 is preferably 0.1 to 1 mm. If distance t1 is more than a lower limit, it will become a binding part with sufficient intensity | strength, and a hollow fiber membrane sheet-like thing will not break easily. If the distance t1 is less than or equal to the upper limit value, the cost can be reduced, and it becomes easy to increase the packing density of the hollow fiber membranes per hollow fiber membrane module.

As a material for forming the first binding portion 18a and the second binding portion 18b, for example, an elastic body having an elongation (E) defined by JIS K6251 of 200% or more can be cited, and the elongation (E) can be 300% or more. An elastic body is preferable. The upper limit of the elongation (E) of the elastic body is not particularly limited, but is usually about 600%.
If the 1st binding part 18a is formed with the said elastic body, the sealing performance between the overlapping 1st binding parts 18a or between the 1st binding part 18a and the side wall parts 20a and 20b of the water collecting pipes 12a and 12b will be explained. Is easily exhibited. Therefore, when the liquid potting resin is poured into the water collecting pipes 12a and 12b, it is easy to suppress the potting resin from leaking to the bottom 20c side from the first binding portion 18a. If the second binding portion 18b is formed of the elastic body, when the liquid potting resin is injected into the water collection pipes 12a and 12b, it is easy to suppress excessive creeping of the potting resin due to capillary action.

As for the durometer hardness prescribed | regulated by JISK6253 of an elastic body, A40-80 are preferable. If the durometer hardness of the elastic body used for the first binding portion 18a is within the above range, it is easy to suppress leakage of the potting resin to the bottom 20c side during injection. If the durometer hardness of the elastic body used for the second binding portion 18b is within the above range, it is easy to suppress damage to the hollow fiber membrane during the air scrubbing process.
The standard of durometer hardness according to JIS K6253 corresponds to ISO 7619.

  As the material of the elastic body, a thermoplastic elastomer is preferable. The type of thermoplastic elastomer can be selected in consideration of environmental resistance and the like according to the environment in which the hollow fiber membrane module is used. Examples of the thermoplastic elastomer include styrene elastomer (TPS), olefin elastomer (TPO), vinyl chloride elastomer (TPVC), ester elastomer (TPC), urethane elastomer (TPU), and amide elastomer (TPA). Etc. Of these, styrene-based elastomers (TPS) are preferred because of their high rubber elasticity and excellent chemical resistance. The material of the elastic body may be one type or two or more types.

  The water collecting pipes 12a and 12b have a semicircular bottom section 20c that connects a pair of long side walls 20a and 20b whose faces face each other and ends in a short direction of the pair of side walls 20a and 20b. And long and plate-like legs 21a and 21b extending from the bottom 20c side of the side walls 20a and 20b. A slit-like opening 22 extending along the longitudinal direction is formed at the other end of the water collecting pipes 12a and 12b in the short direction. Thus, the water collection pipes 12a and 12b are long members. The shape of the cross section orthogonal to the longitudinal direction on the opening 22 side of the water collecting pipes 12a and 12b is a U-shape.

  In the laminate 2 of the hollow fiber membrane module 1, the four hollow fiber membrane sheet-like materials 10 are stacked such that the first binding portions 18a are in close contact with each other and the second binding portions 18b are in close contact with each other. . Thus, in the state where the hollow fiber membrane sheets 10 are stacked, end portions 2a and 2b in the length direction of the laminate 2, that is, the first binding portions 18a of the hollow fiber membrane sheets 10 are provided. Further, the end portions 11a and 11b are inserted into the water collecting pipes 12a and 12b.

1-30 mm is preferable and, as for the distance L of the 2nd binding part 18b and the opening part 22 of the water collection pipes 12a and 12b, 3-10 mm is more preferable. If the distance L is equal to or greater than the lower limit value, it becomes easy to inject liquid potting resin (potting liquid) into the water collecting pipes 12a and 12b, so that the potting resin is sufficiently spread in the water collecting pipe and cured. This makes it easier to reduce the leak rate. If the distance L is less than or equal to the upper limit value, it is easy to suppress a decrease in the effective membrane area of the hollow fiber membrane module.
In the case of the second bundling portion 18b on the side of the water collecting pipe 12b, the distance L is from the opening 22 of the water collecting pipe 12b in the length direction of the hollow fiber membrane 16 (from the front end surfaces of the side wall portions 20a and 20b). This is the length to the side end of the second bundling portion 18b on the water collecting pipe 12b side. The same applies to the distance L of the second bundling portion 18b on the water collecting pipe 12a side.

  On the inner surfaces of the side wall portions 20a and 20b of the water collecting pipes 12a and 12b in this example, step portions 24 extending along the longitudinal direction of the water collecting pipes 12a and 12b are formed at positions facing each other. The distance (clearance) between the side wall 20a and the side wall 20b on the bottom 20c side is smaller than the distance (clearance) between the side wall 20a and the side wall 20b on the opening 22 side. In this example, the position of the step portion 24 and the side end on the center side in the longitudinal direction of the hollow fiber membrane 16 in the first binding portion 18a coincide with each other.

  The distance between the side wall portion 20a and the side wall portion 20b on the bottom 20c side of the stepped portion 24 is the total thickness of the first bundling portion 18a portion of the stacked hollow fiber membrane sheet 10, that is, the end portion 2a of the laminate 2. It is set to be about the same as or slightly smaller than the thickness of 2b. Thereby, the part of the 1st binding part 18a of the hollow fiber membrane sheet-like thing 10 in the laminated body 2 closely_contact | adheres to the inner surface of side wall part 20a, 20b, and a sealing property is exhibited. Further, the stacked first bundling portions 18a are also in close contact with each other in a liquid-tight manner, and a sealing property is exhibited.

  The material of the water collecting pipe is preferably one having excellent mechanical strength and durability, such as polycarbonate, polysulfone, polyolefin, PVC (polyvinyl chloride), acrylic resin, ABS resin, modified PPE (polyphenylene ether), etc. Can be mentioned. The material of the water collecting pipe may be one type or two or more types.

The potting part 14 is formed so that the part from the 1st binding part 18a to the opening part 22 in the outer side of each hollow fiber membrane 16 in the water collection pipes 12a and 12b may be filled. Thereby, the water collection space 26 is formed in the bottom 20c side rather than the potting part 14 and the 1st binding part 18a in the water collection pipes 12a and 12b.
In the hollow fiber membrane module 1, the treated liquid filtered by the plurality of hollow fiber membranes 16 forming the hollow fiber membrane sheet 10 is once collected in the water collection space 26 of the water collection pipes 12a and 12b. The water collecting pipes 12a and 12b are taken out to the outside of the hollow fiber membrane module 1 through a water intake port 28 formed at the end in the longitudinal direction.

  Examples of the potting resin that forms the potting portion 14 include epoxy resins, unsaturated polyester resins, polyurethane resins, silicone fillers, and various hot melt resins. The potting resin that forms the potting portion 14 may be one type or two or more types.

As shown in FIG. 5, the first flat plate portion 116 is in a state where the columns 110 and 112 are laid down. And the 2nd flat plate part 118 becomes horizontal. Further, as shown in FIGS. 6 and 7, when the support columns 110 and 112 are upright, the first flat plate portion 116 and the second flat plate portion 118 are folded downward and suspended from the rod-shaped portion 114.

A plurality of hollow fiber membrane sheets 10 are laminated on 116 and the second flat plate portion 118 to form a laminate 2. At this time, the length direction of each hollow fiber membrane 16 in each hollow fiber membrane sheet 10 is set to be orthogonal to the axial direction of the rod-like portion 114. The end surfaces 10a and 10b in the length direction of the hollow fiber membrane 16 in each hollow fiber membrane sheet-like product 10 when laminated on the first flat plate portion 116 and the second flat plate portion 118 in the horizontal state must be neatly aligned.

In addition, in this invention, it is not limited to the aspect which presses an abutting member on the end surface of each hollow fiber membrane sheet-like thing of a laminated body, For example, the end surface of each hollow fiber membrane sheet-like thing of a laminated body is contact member It may be a mode applied to the above.

  In this example, in the state where the laminate 2 is bent in the length direction of the hollow fiber membrane 16 with the U-turn portion 2c facing upward and suspended from the rod-like portion 114, each hollow fiber membrane sheet-like shape positioned below is formed. Two holding plates 121 are arranged on both sides of the object 10 near the ends 11a and 11b. The two holding plates 121 are not in contact with the hollow fiber membrane sheet 10 when no vibration is applied to the end portions 11 a and 11 b of the hollow fiber membrane sheets 10. By arranging such a restraining plate 121, when the end portions 11a and 11b of each hollow fiber membrane sheet 10 are vibrated by the contact member 120, the end portions 11a and 11b are excessively bent. It becomes easy to suppress. Therefore, it can be easily suppressed that the portions near the end portions 2a and 2b of the laminated body 2 are excessively swollen and the posture of the laminated body 2 is unstable.

  In the present invention, as in this example, each hollow fiber is obtained by repeating the operation of contacting each of both end faces in the length direction of the hollow fiber membrane in each hollow fiber membrane sheet of the laminate with the contact member. It is preferable to align both end faces of the membrane sheet. Both hollow fiber membrane sheet materials are brought into contact with both end faces of each hollow fiber membrane sheet material, and vibrations are applied to both ends of the hollow fiber membrane sheet materials, respectively. It becomes easy to align the end faces of the. In addition, for example, when the length of the hollow fiber membrane sheet is short, both end surfaces can be obtained simply by bringing a contact member into contact with one end surface in the length direction of each hollow fiber membrane sheet and applying vibration. If the contact members can be aligned, an operation of repeatedly applying the contact member to only one end surface may be performed.

  In addition, as in this example, the present invention is in contact with the end face of each hollow fiber membrane sheet of the laminate in a state where the laminate is curved in the length direction of the hollow fiber membrane so as to protrude upward. The contact member is preferably applied. Moreover, in this case, it is more preferable that the end surface and the contact member are brought into contact with each other in a state where the laminated body is suspended. By setting the laminated body in a suspended state, it becomes easy to simultaneously contact both end surfaces of the hollow fiber membranes in the length direction of each hollow fiber membrane sheet-like material with the contact member. Moreover, the operation | work which attaches a water collection pipe | tube to the edge part of the laminated body which aligned the end surface of each hollow fiber membrane sheet-like thing becomes easy so that it may mention later.

  The operations of aligning one end surface 10a in the length direction of the hollow fiber membrane 16 in each hollow fiber membrane sheet-like material 10 in the laminate 2 and the operation of aligning the other end surfaces 10b may be performed separately, You may do it at the same time. In the present invention, from the viewpoint of high work efficiency and high productivity, both end surfaces in the length direction of the hollow fiber membranes in the respective hollow fiber membrane sheet-like materials of the laminate and the contact member are simultaneously applied, It is preferable to align both end faces.

Further, in the present invention, in addition to aligning both end faces in the length direction of the hollow fiber membrane in each hollow fiber membrane sheet in the laminate, further, at least one side end face of each hollow fiber membrane sheet It is preferable to repeat the operation of applying the width direction adjusting member to align the side end surfaces of the hollow fiber membrane sheets. For example, as illustrated in FIG. 9, each hollow fiber membrane sheet-like material in the laminate 2 that is hung and bent in the length direction so that the U-turn portion 2 c is on the upper side using the width direction adjusting member 128. It is preferable to align the 10 side end faces 10c and 10d.
The width direction adjusting member 128 includes a vibrator 130 and a contact plate 132 provided on the vibrator 130, and the upper surface of the contact plate 132 is in contact with the side end surface 10 c of the hollow fiber membrane sheet-like material 10. This is a flat surface 132a. The side end surface of each hollow fiber membrane sheet 10 in the laminate 2 is caused by repeatedly applying the flat surface 132a of the contact plate 132 of the width direction adjusting member 128 to the side end surface 10c of each hollow fiber membrane sheet 10 to vibrate. 10c and 10d can be aligned.

  As in the present embodiment, the length direction of the hollow fiber membrane in each hollow fiber membrane sheet in a state in which the laminate is bent and suspended in the length direction of the hollow fiber membrane so that the U-turn portion is on the upper side When the end surfaces are aligned, it is preferable to hold a portion near the end of the laminate with a holding member such as a clamp. For example, as shown in FIG. 10, in the state where the end surfaces 10a, 10b in the length direction of the hollow fiber membrane 16 in each hollow fiber membrane sheet-like product 10 are aligned, the portions near the end portions 2a, 2b of the laminate 2 are It is preferable to hold it with a clamp 134. By holding the holding member in this manner, the ends of the hollow fiber membrane sheet-like materials are not fixed with an adhesive or the like. It can be easily suppressed that the end face is disturbed again. Therefore, it is possible to reduce the work load of fixing with an adhesive.

  In the end portions 2a and 2b of the laminate 2, when the end face 10a of each hollow fiber membrane sheet-like material 10 and the end face 10b are largely displaced and a portion where the first binding portions 18a are not in close contact with each other occurs, When the liquid potting resin is injected with the 12a and 12b attached, the potting resin leaks to the bottom 20c side from the first binding portion 18a. Therefore, from the point of more stably suppressing the leakage of potting resin to the bottom side than the bundling portion in the water collection pipe, after performing the operation of aligning the end faces of each hollow fiber membrane sheet, the deviation of the end faces It is preferable to inspect.

  For this reason, in the present invention, after repeating the operation of applying the contact member to align the end faces in the length direction of the hollow fiber membrane sheet-like materials of the laminate, the displacement between these end faces is measured by the distance measuring sensor. It is preferable to do. Specifically, for example, after the end surfaces 10a and 10b in the length direction of the hollow fiber membrane sheet-like material 10 of the laminate 2 are aligned by the contact member 120, as shown in FIG. 9 and FIG. The distance measurement sensor 140 and the laminate 2 are moved relative to each other in the width direction of 2, and the end face 10a of each hollow fiber membrane sheet 10 is scanned by the distance measurement sensor 140 to measure the deviation between the plurality of end faces 10a. It is preferable. Similarly, it is preferable that the distance between the plurality of end faces 10b is also measured by the distance measuring sensor 140. Thus, by measuring with the distance measuring sensor, after aligning the lengthwise end surfaces of the hollow fiber membranes in each hollow fiber membrane sheet using the contact member, the degree to which the end surfaces are aligned is determined. Can be determined.

  The method of moving the laminated body 2 relative to the distance measuring sensor 140 is not particularly limited, and a method of moving the laminated body 2 while fixing the position of the distance measuring sensor 140 may be used. Alternatively, the distance measuring sensor may be moved by fixing the distance sensor.

  The distance measuring sensor is not particularly limited as long as it can measure the deviation between the end faces of each hollow fiber membrane sheet, and examples thereof include a smart sensor, two-dimensional shape measuring sensor type ZG2 series manufactured by OMRON Corporation. .

When the deviation between the end surfaces measured by the distance measuring sensor is equal to or greater than a predetermined value, it is preferable that the end surfaces are aligned by repeating the operation of contacting the end surface of each hollow fiber membrane sheet of the laminate with the contact member again. In this way, by performing again the operation of aligning the end surfaces of the contact members based on the results of measurement by the distance measuring sensor, the end surfaces in the length direction of the hollow fiber membranes in each hollow fiber membrane sheet-like material in the laminate are more It can be in a state of being aligned with high accuracy.
For example, when the maximum value X (FIG. 13) of the displacement of the end surface 10a in the length direction of each hollow fiber membrane sheet 10 measured by the distance measuring sensor 140 is 2 mm or more, each hollow fiber membrane sheet The operation of applying the flat surface 124a of the contact member 120 to the end surface 10a of the object 10 is repeated to align the end surface 10a.

  After aligning the lengthwise end faces 10a, 10b of the hollow fiber membrane 16 in each hollow fiber membrane sheet 10 of the laminate 2, as shown in FIG. 12, each of the end portions 2a, 2b of the laminate 2 is shown. The water collecting pipes 12a and 12b are respectively attached to. In the case of the water collecting pipes 12a and 12b in this example, the end portions of the side wall 20a and the side wall 20b are separated and the opening 22 is opened by picking the leg 21a and the leg 21b close to each other. By doing in this way, edge part 2a, 2b of the laminated body 2 can be easily inserted in the water collection pipes 12a, 12b.

  Next, a liquid potting resin (potting liquid) is injected into the gap between the stacked bodies 2 in the water collecting pipes 12a and 12b and cured to fix the stacked body 2 to the water collecting pipes 12a and 12b in a liquid-tight manner. In the portion of the hollow fiber membrane sheet 10 where the first binding portion 18a is provided, the periphery of each hollow fiber membrane 16 is filled with the first binding portion 18 as described above. Moreover, the 1st binding part 18a of each hollow fiber membrane sheet-like object 10 is closely_contact | adhered, and the part of the side part 20c rather than the level | step-difference part 24 in the side wall part 20a, 20b and the 1st binding part 18a are also closely_contact | adhering. Therefore, the potting resin injected into the water collecting pipes 12a and 12b is blocked by the first bundling portion 18a and does not leak to the bottom portion 20c side.

  The method for injecting the potting resin is not particularly limited, and a known method can be employed, and examples thereof include a method for injecting the potting resin by discharging from a nozzle. For example, a potting resin is injected into the water collecting pipes 12a and 12b attached to the lengthwise ends 2a and 2b of the hollow fiber membrane 16 in the laminate 2, and the water collecting pipes 12a and 12b are connected to the ends 2a of the laminate 2. , 2b may be used.

As the potting device, a known device can be used. As a potting device, for example, a device provided with a holding means for holding the laminate 2 and the water collecting pipes 12a and 12b and a nozzle for injecting a potting resin into the held water collecting pipes 12a and 12b can be cited. For example, by discharging the potting resin from the nozzle while relatively moving the nozzle in the length direction of the water collecting pipes 12a and 12b, that is, the width direction of the stacked body 2, the end portions 2a and 2b of the stacked body 2 are discharged. Potting resin can be injected and fixed in the water collecting pipes 12a and 12b attached to the pipe.
In this invention, it is preferable to attach a water collection pipe | tube simultaneously to each of the both ends of the length direction of a laminated body from the point of productivity.

  As described above, in the present invention, by repeating the operation of applying at least one end face in the length direction of the hollow fiber membrane and the contact member in each hollow fiber membrane sheet-like material of the laminate, each hollow fiber membrane Align the end faces of the sheet-like material. In this way, in the laminate in which the hollow fiber membrane sheet-like material is laminated, if the contact member is repeatedly applied to the end surface of each hollow fiber membrane sheet-like material and the end surfaces are aligned using the vibration, Even their end faces can be aligned.

In the present invention, the laminating operation is easy as compared with the case where the hollow fiber membrane sheet-like materials are laminated while aligning the end faces of each sheet. In addition, the work of laminating a plurality of hollow fiber membrane sheets and aligning the end faces is substantially the same regardless of the number of hollow fiber membrane sheets, so even if the number of laminated hollow fiber membrane sheets increases. Increase in work load can be suppressed.
