The hollow strand things such as hollow fiber membrane are such as by such as under type acquisition: the resin combination taking poly-mer as main component is used as stoste and carries out spinning by various spinning process, is obtained afterwards (patent documentation 1 ~ 3 etc.) by figuration.

And, these hollow strand things are processed to hollow fiber membrane module, this hollow fiber membrane module has the form such as hollow fiber membrane being formed as pencil, hollow fiber membrane is formed as sheet and by the various forms such as its stacked form (with reference to patent documentation 1,2).

In this case, in operation (cleaning, drying, pencil etc.) after spinning is carried out to hollow fiber membrane (hollow strand thing), when carrying hollow fiber membrane, utilize the propulsive effort of the electrical motor etc. by being linked to S. A. and carry out the driven roller that rotates, being carried out the free roll etc. rotated by the power of hollow fiber membrane be transferred.Hollow fiber membrane is transferred along the silk road these rollers being configured in formation in space, carries out the various process in each operation during this period.

As shown in fig. 55, when carrying hollow fiber membrane (strand thing F) in the midway two driven rollers 1110,1120 being configured in a road, the Feeding speed Va of the hollow fiber membrane produced by the driven roller 1110 and Feeding speed Vb of hollow fiber membrane produced by driven roller 1120 can produce difference slightly.The difference of Feeding speed Va and Feeding speed Vb results from the difference of external diameter of driven roller 1110,1120, the difference of the rotating speed of the electrical motor of driven roller 1110,1120, the external diameter in hollow fiber membrane cross section or the unequal of circularity on the length direction of hollow fiber membrane.

When only carrying a hollow strand thing, by becoming constant torque to eliminate the problems referred to above motor control.But, when carrying the hollow strand thing of more than two, when motor control being become constant torque, total tension force of the hollow fiber membrane of more than two is controlled as constant simultaneously, therefore, the tension force of every root hollow fiber membrane that cannot control respectively.Therefore, put on for every root hollow fiber membrane the change degree of the tension force of described hollow fiber membrane different when, the variation of the tension force putting on described hollow fiber membrane cannot be relaxed for every root hollow fiber membrane.

When carrying the hollow strand thing of more than two simultaneously, as the variation method relaxing the tension force putting on described hollow strand thing for every root hollow strand thing, can consider to be configured in the midway in silk road the method (patent documentation 3, particularly Fig. 1) such as dance roller relaxing tension change for every root hollow strand thing.But, when being carried out carrying by multiple hollow fiber membrane close-packed arrays, there is the situation that difficulty is set of dance roller etc. due to the restriction in space simultaneously.

In addition, as hollow fiber membrane module, manufacture and there is form hollow fiber membrane being formed as pencil, hollow fiber membrane is formed as sheet and by the hollow fiber membrane module of the various forms such as its stacked form (with reference to patent documentation 1,3), hollow fiber membrane module is to be used as the manufacture of sterilized water, drinking water, height pure water, and the multiple use such as the purification of air is used.

The hollow fiber membrane module of stacked hollow fiber membrane flap form is by hollow fiber membrane module fixing for stacked multiple hollow fiber membrane flaps with shell.Shell is configured to, and the both ends of multiple hollow fiber membrane are housed in the inside of shell.

Generally speaking, hollow fiber membrane module manufactures in the following way: under the state arranged according to desired spacing by hollow fiber membrane, trimmed into specified length, and by by welding between hollow fiber membrane or bonding and be formed as sheet, and flap is stacked.

As the manufacturing installation of hollow fiber membrane flap, there will be a known: hollow fiber membrane gapless is spirally wound in its thermal welding at least partially after on cylinder or gal frame, and by the manufacture method of the hollow fiber membrane flap of this thermal welding partial cut, and employ the manufacture method (with reference to patent documentation 4,5) of hollow fiber membrane flap of raschel machine.

In addition, there will be a known the manufacture method of following hollow fiber membrane flap: the hollow fiber membrane that can supply continuously is to be wound in described plural roller around the mode of plural roller, the top ends of be wound around described hollow fiber membrane is connected with adjacent hollow fiber membrane and forms colyliform portion, or, by the colyliform portion lodge made in advance on plural roller, under being connected in the top ends of the hollow fiber membrane that can supply continuously further the state connecting described colyliform portion, described plural roller is rotated and after being wound around hollow fiber membrane, hollow fiber membrane broad ways is fixed into sheet and forms fixed part, then cut (with reference to patent documentation 6) along described fixed part.

Summary of the invention

Invent problem to be solved

In the manufacturing installation of hollow fiber membrane flap in the past, in invention such as described in patent documentation 4, when needing the sheet length changing hollow fiber membrane flap, owing to needing to change the diameter of cylinder or the interval of framework, therefore existing and changing very difficult problem.

In addition, in the invention described in patent documentation 5, repeat to stop transverse shifting near knitting end, the action again accelerated when transverse shifting round about, executes loaded problem to hollow fiber membrane when therefore there is acceleration/deceleration.

And, in invention described in patent documentation 6, as shown in Figure 1A ~ 1D, when two rollers 2110,2120 are configured in the midway in a road and are wound around hollow fiber membrane, the Feeding speed Vb sometimes at the Feeding speed Va at a position of hollow fiber membrane length direction and the b position of hollow fiber membrane length direction produces difference slightly.

Herein, the inequality (working accuracy) in the roller footpath that the difference of Feeding speed Va and Feeding speed Vb results from the Width of roller 2110,2120, pair roller 2110,2120 carries out the difference of the rotating speed of the electrical motor driven, the external diameter (circularity) on the length direction of hollow fiber membrane unequal.

That is, more almost the accumulation slightly of Feeding speed Va and Feeding speed Vb, thus, produces and causes from faults such as driven roller disengagings because of hollow fiber membrane overrelaxation, or become hollow fiber membrane damage reason because of over-tension on the contrary.

When a conveying hollow fiber membrane, constant torque is become to eliminate the problems referred to above by the motor control that pair roller is carried out driving.But, side by side when conveying hollow fiber membrane, be that constant mode controls to put on total tension force of multiple row hollow fiber membrane, the tension force of every root hollow fiber membrane cannot be controlled respectively.

Under carrying the situation of the hollow fiber membrane of more than two (also comprising the situation by the roller of a hollow fiber membrane more than two being wound around multi-turn) simultaneously, as the variation method relaxing the tension force putting on described hollow membrane for every root hollow fiber membrane, can consider that the midway in silk road is configured for the methods (patent documentation 3) such as the dance roller of the variation relaxing tension force for every root hollow fiber membrane.

But, multiple row hollow fiber membrane is transferred around the plural roller close-packed arrays being configured to desired girth, therefore, due to the restriction in space, dance roller etc. difficulty is set.The present invention makes under the circumstances, the invention provides hollow strand thing conveying roller, and use the manufacture method of hollow strand thing of described roller, hollow strand thing is put on (below for mitigation without the need to increasing in addition on silk road, also referred to as strand thing) the dance roller of variation of tension force or tension change reliever, even if when carrying the hollow strand thing of more than two at the same time, the variation of the tension force putting on described hollow strand thing also can be relaxed for each hollow strand thing.

In addition, there is provided a kind of not by the precision of mechanical device or hollow strand thing mass deviation (herein, mass deviation refers to that the inequality of the external diameter of macaroni yarn length direction and/or circularity, elongation characteristics are unequal) impact, the stably manufacture method of the flap (such as hollow fiber membrane flap) of the hollow strand thing that factory length is uneven less and manufacturing installation.

(the 1st embodiment of conveying roller)

Figure 41 represents that hollow strand thing conveying roller of the present invention (below, is also only recited as conveying roller.) the lateral plan of the 1st embodiment of conveying roller, Figure 42 is end view drawing.

Conveying roller 1010 comprises: the columned roller main body 1014 with S. A. 1012; And at the raised line parts 1016 (tension change mitigation unit) extended abreast with S. A. 1012 that the outer peripheral face of roller main body 1014 is arranged, these raised line parts 1016 observe the multiple positions being circumferentially arranged on circumference in equal parts at spaced intervals from end face direction.

As roller main body 1014, as long as use the parts identical with common conveying roller (driven roller, free roll etc.), without particular limitation of material, size etc.

Raised line parts 1016 are formed by having flexible material.Having flexible material can according to the variation of tension force putting on hollow strand thing, namely hollow strand thing relative to the power that tightly wraps of conveying roller 1010 variation and deflection is suitably changed.

About making deflection change, the distance (radius of rotation) from the S. A. 1012 of roller main body 1014 to the hollow strand thing connected with raised line parts 1016 is namely made to change.

Change about from S. A. 1012 to the distance of hollow strand thing, namely the Feeding speed of hollow strand thing changes.

Feeding speed about hollow strand thing changes, and the tension force namely putting on hollow strand thing changes.

Therefore, relax unit by having raised line parts 1016 that flexible material the forms tension change as the variation relaxing the tension force putting on described hollow strand thing for every root hollow strand thing and play a role.

Preferably, raised line parts 1016 are circumferentially arranged on more than two positions at spaced intervals on the outer peripheral face of roller main body 1014.When being provided with in the mode of the entirety circumferentially not covering the outer peripheral face of roller main body 1014 at spaced intervals sheet member (the tension change mitigation unit) be made up of the material with flexibility, the position that hollow strand thing contacts with sheet member becomes long, hollow strand thing is disperseed throughout the position that hollow strand thing contacts with sheet member relative to the power that tightly wraps of conveying roller 1010, therefore, there is the situation that the change of the deflection of sheet member is insufficient.

From fully relaxing the viewpoint putting on the variation of the tension force of hollow strand thing, raised line parts 1016 are preferably circumferentially located at 2 ~ 32 positions at spaced intervals, are more preferably and are located at 4 ~ 16 positions, be more preferably located at 8 ~ 12 positions.

And the viewpoints such as the broken string that cause unequal from the tension force prevented owing to applying the hollow silk connected with roller, the raised line parts 1016 being preferably more than two positions are circumferentially equally spaced arranged.

In illustrated example, raised line parts 1016 are formed as section rectangle as shown in figure 43, but are not defined as this shape in the present invention.From the viewpoint reduced relative to the damage of hollow strand thing, as shown in figure 44, chamfering greatly of also can trying one's best in bight.

From reducing relative to the viewpoint of the damage of hollow strand thing, it is high that the surface of raised line parts 1016 is preferably flatness.As shown in figure 45, also can as required the guard block 1018 (one side splicing tape, film etc.) of surface smoothing be wrapped on raised line parts 1016.

As having flexible material, from the viewpoint that the intensity of variation of deflection is large, be preferably elastic body.As elastic body, various rubber (poly-urethane rubber, silaatic, viton, natural rubber, butyl rubber, EP rubbers, poly-chloroprene rubber etc.), the sponge of various rubber, flexibel polyurethane, soft PVC, foaming body (polyethylene, polystyrene, ethylene vinyl acetate acetate multipolymer etc.) can be listed.

The hardness (Shore A hardness) of raised line parts 1016 is preferably 5 ~ 70A, is more preferably 10 ~ 50A, more preferably 15 ~ 25A.The hardness of raised line parts 1016 is suitably selected according to the external diameter, tension force etc. of strand thing.

In addition, the height at the position of most projection from the outer peripheral face of roller main body 1014 of raised line parts 1016 is 0.5mm ~ 5mm, and the width of the length direction of raised line parts is width identical with conveying roller 1010, and the width of Width is 5mm ~ 20mm.

Then, the conveying of the hollow strand thing that the conveying roller 1010 of use the 1st embodiment is carried out is described.

As shown in Figure 46 A, when carrying hollow strand thing F in the midway driven roller be made up of common driven roller 1110 and conveying roller of the present invention 1010 being configured in a road, the raised line parts 1016 of conveying roller 1010 make deflection suitably change according to hollow strand thing F relative to the tightly wrapping power of conveying roller 1010, relax the tension change caused due to the Feeding speed difference of the hollow strand thing F between driven roller 1110 and conveying roller 1010 thus.

That is, when the Feeding speed V2 of the hollow strand thing F produced by conveying roller 1010 is faster than the Feeding speed V1 of the hollow strand thing F produced by driven roller 1110, the tension force of the hollow strand thing F between driven roller 1110 and conveying roller 1010 improves bit by bit.So hollow strand thing F increases relative to the power that tightly wraps of conveying roller 1010, as shown in the bottom of Figure 47, the deflection of raised line parts 1016 increases.Thus, the distance (radius of rotation) from the S. A. 1012 of conveying roller 1010 to the hollow strand thing F connected with raised line parts 1016 shortens, and the Feeding speed V2 of hollow strand thing F is slack-off.Thus, the tension force of the hollow strand thing F between driven roller 1110 and conveying roller 1010 reduces, i.e. reinstatement the figure of the deflection of raised line parts 1016 as shown in the central authorities of Figure 47.

On the contrary, when the Feeding speed V2 of the hollow strand thing F produced by conveying roller 1010 is slower than the Feeding speed V1 of the hollow strand thing F produced by driven roller 1110, the tension force of the hollow strand thing F between driven roller 1110 and conveying roller 1010 reduces bit by bit.So hollow strand thing F reduces relative to the power that tightly wraps of conveying roller 1010, as shown in the top of Figure 47, the deflection of raised line parts 1016 reduces.Thus, the distance (radius of rotation) from S. A. 1012 to the hollow strand thing F connected with raised line parts 1016 is elongated, and the Feeding speed V2 of hollow strand thing F accelerates.Thus, the tension force of the hollow strand thing F between driven roller 1110 and conveying roller 1010 increases, i.e. reinstatement the figure of the deflection of raised line parts 1016 as shown in the central authorities of Figure 47.

In addition, in order to obtain hollow strand thing flap, being preferably and configuring conveying roller 1010 abreast as shown in Figure 46 B.

In addition, in Fig. 3 and Fig. 4, symbol 4 is the 1st ultrasonic wave coating machines (linkage unit), 1st ultrasonic wave coating machine 4 has following function: by the hollow sent from bobbin 5 strand thing F with under the state not being wound in the peripheral part of the 1st roller 1 and the 2nd roller 2 overlappingly around the mode of the 1st roller 1 and the 2nd roller 2, form connecting portion C by carrying out deposition to the top A of hollow strand thing F and hollow strand thing F self and fixing as illustrated in fig. 5.

In framework 3, anvil block 8 is provided with between the 1st roller 1 and the 2nd roller 2, to be configured with cantilever (Japanese: ホー Application) 7 across the mode of hollow strand thing F above this anvil block 8, form the 2nd ultrasonic wave coating machine 9 (fixed cell) by cantilever 7 and anvil block 8.

2nd ultrasonic wave coating machine 9 have throughout the 1st roller 1 and the 2nd these two rollers of roller 2 Width (direction orthogonal with the length direction of hollow strand thing F) hollow strand thing F is fixed into the function of sheet.In this embodiment, two place fixed part B (with reference to Figure 10) are formed while the throughput direction of hollow strand thing separates predetermined distance.In this case, fixed cell can have the mechanism that once can form two place's fixed parts, after also can fixing a place in desired position, makes roller rotate and by amount suitable with this fixed part width for the conveying of hollow strand thing, again form fixed part afterwards.

In addition, if the 2nd ultrasonic wave coating machine 9 is configured to be moved along winding direction by not shown actuating device, even if then hollow strand thing F is in halted state and also can carries out deposition to different parts.In addition, by the position of deposition, the shape (hollow shape) keeping hollow strand thing F is not needed.

In addition, in Fig. 3, symbol 11 represents ultrasonic cutter (cutting unit), and broad ways between the two place fixed part B separate predetermined distance on the throughput direction of hollow strand thing formed by the 2nd ultrasonic wave coating machine 9 is cut off by this ultrasonic cutter 11.

As shown in Figure 5, the 1st roller 1 and the 2nd roller 2 have the groove of the plural circumference of the broad ways arrangement closely formed abreast with identical spacing P, and this groove is made up of mountain portion M and valley V.This groove is not be formed as screw-shaped, but formed independently of each other.The diameter of spacing P foundation hollow strand thing F of groove and the integration density of the desired hollow fiber membrane of desired hollow strand thing flap determine, when in advance spacing P being increased more than a circle (1 ~ 3%) relative to the diameter of hollow strand thing F, the grooved roller of the hollow strand thing in manufacturing process described later imports more smooth and easy, is adjacent to Quality Down, dislocation/windings etc. that the contact between the hollow strand thing that is transferred produces and is also difficult to generation.

In addition, it is describe the shape of circular arc that the shape of groove is not defined as the shape observed from the side as illustrated in fig. 5, and can be such as the shape that mountain portion M is connected with valley V straight line, also can be the shape that trench bottom is smooth.As in the present embodiment, by groove portion being formed as the shape describing circular arc, hollow strand thing F and groove are adjacent to further.

The hardness (Oscar C hardness) of raised line parts 1016 is preferably 1 ~ 80 degree, is more preferably 3 ~ 50 degree, more preferably 5 ~ 20 degree.The hardness of raised line parts 1016 is suitably selected according to the external diameter, tension force etc. of hollow strand thing.

Then, illustrate the manufacturing installation 100 of the hollow strand thing flap of the 1st embodiment conveying roller 1010 is applied to the 1st roller 1 and the 2nd roller 2 when the tension change reliever of hollow strand thing.

As shown in Figure 46 A and B, when conveying roller 1010 being used for the 1st roller 1 and the 2nd roller 2 and being wound around hollow strand thing F, the raised line parts 1016 of conveying roller 1010 make deflection suitably change according to hollow strand thing F relative to the tightly wrapping power of conveying roller 1010, relax the tension change caused due to the Feeding speed difference of the hollow strand thing F between driven roller 1110 and conveying roller 1010 thus.

Herein, by the roller having the tension change shown in Figure 42 etc. and relax unit being used for the manufacture method of the hollow strand thing flap shown in Fig. 3 etc., suppress the elongation of the hollow strand thing caused due to tension change uneven, therefore, it is possible to be not subject to the impact of the precision of mechanical device, the mass deviation of hollow strand thing and stably obtain the uneven less hollow strand thing flap of the such length of Fig. 2 A.

That is, when the Feeding speed V2 of the hollow strand thing F produced by conveying roller 1010 is faster than the Feeding speed V1 of the hollow strand thing F produced by driven roller 1110, the tension force of the hollow strand thing F between driven roller 1110 and conveying roller 1010 increases bit by bit.So hollow strand thing F increases relative to the power that tightly wraps of conveying roller 1010, as shown in the bottom of Figure 47, the deflection of raised line parts 1016 increases.Thus, the distance (radius of rotation) from the S. A. 1012 of conveying roller 1010 to the hollow strand thing F connected with raised line parts 1016 shortens, and the Feeding speed V2 of hollow strand thing F is slack-off.Thus, the tension force of the hollow strand thing F between driven roller 1110 and conveying roller 1010 reduces, i.e. reinstatement.

On the contrary, when the Feeding speed V2 of the hollow strand thing F caused by conveying roller 1010 is slower than the Feeding speed V1 of the hollow strand thing F caused by driven roller 1110, the tension force of the hollow strand thing F between driven roller 1110 and conveying roller 1010 reduces bit by bit.So hollow strand thing F reduces relative to the power that tightly wraps of conveying roller 1010, as shown in the top of Figure 47, the deflection of raised line parts 1016 reduces.Thus, the distance (radius of rotation) from S. A. 1012 to the hollow strand thing F connected with raised line parts 1016 increases, and the Feeding speed V2 of hollow strand thing F accelerates.Thus, the tension force of the hollow strand thing F between driven roller 1110 and conveying roller 1010 increases, i.e. reinstatement.

In illustrated example, conveying roller 1010 of the present invention is used as driven roller, but, also can increase conveying roller 1010 of the present invention between existing two driven rollers and be used as free roll.In addition, in order to relax the variation of the tension force putting on hollow strand thing, without the need to increasing new roller, the device except existing roller, device on silk road, just can relax the variation of the tension force putting on described hollow strand thing for every root hollow strand thing by means of only the existing driven roller of displacement, from this point of view, be preferably conveying roller 1010 of the present invention as driven roller.
