In addition, the hollow fiber membrane bundle in the present embodiment is to be made of micro-porous film with strainability etc., is that resin etc. constitutes by polysulfones for example.The hollow fiber membrane bundle both can be that drying regime also can be a moisture state.In order to be filled in the tubular box, from the easy to handle aspect, the hollow fiber membrane bundle of preferred moisture state, but must to carry out drying and handle in order to prevent to take place in the subsequent handling embedding to engage bad.When drying regime, do not need dry the processing, but because static electrification and macaroni yarn repels each other, do not assemble so be difficult to handle, is compared with moisture state, the frictional resistance that tends to macaroni yarn frictional resistance, tow and tubular box each other is big and be difficult to filling.
Device shown in Figure 1 has: in be equipped with and vacate at interval and the tow pilot unit 8 of a pair of drum type roller that rotates freely (external diameter at rotating shaft direction both ends is greater than the tubular roller of the external diameter at middle part) 6 of configuration, tow U word makeup with the press-in device that moves back and forth between this a pair of drum type roller 6 are put 3, are configured between a pair of drum type roller 6 and tow drawn-back device 5 thereunder, during operation, configuration tubular box 2 between tow drawn-back device 5 and a pair of drum type roller 6.
Tow pilot unit 8 have can traverse hollow fiber membrane bundle 1 such concavity groove.Use drum type roller 6 to suppress the hollow fiber membrane damage when getting one's things ready hollow fiber membrane into the cartridge type box described later.The middle part of the concavity groove of this tow pilot unit is provided with and can makes crooked hollow fiber membrane bundle 1 lead to the hole of tubular box 2.
The makeup of tow U word is put 3 and is had the pressing parts that is made of 2 dull and stereotyped 3a, 3b, sets pressing parts and makes it between a pair of drum type roller 6, and promptly the length direction of the tubular box 2 of configuration moves back and forth as described later.Pressing parts is the reciprocating structure that can carry out necessary amount by drive units such as pulse motors.
Pressing parts can be the tabular parts of a slice, but preferably is made of 2 dull and stereotyped 3a, 3b as present embodiment.Consequently, can use two pressing parts when making hollow fiber membrane bundle 1 bend to the U font, a slice when reality is drawn in tubular box 2 with hollow fiber membrane in two makes it and tow drawn-back device 5 same moved further as guide way.
And from the aspect of easy importing tubular box 2, only the dull and stereotyped 3a that uses when making hollow fiber membrane bundle 1 bend to the U font is for dividing the shape of two forks, and the part that contacts with macaroni yarn is chamfered and is worked into the degree of not damaging macaroni yarn.In addition, leading section to the pressing parts 3b that when packing tubular box 2 into, also uses, also can be for dividing the shape of two forks as pressing parts 3a, but because in box, be not necessarily limited to the direction vertical with being pressed into direction, divide the bight of the part of two forks to become interference on the contrary, so be preferably smooth.
Tow drawn-back device 5 is provided in tow U word makeup with respect to tubular box 2 and puts 3 opposition side, the 5b of travel mechanism that have the sheet handle sturcture 5a of a part of controlling easy sliding property sheet 4 in tubular box 2, moves back and forth at the length direction of tubular box 2 etc.After making 1 bending of hollow fiber membrane bundle with described pressing parts, carry out in tubular box 2, controlling the part of easy the to be sliding property sheet 4 between hollow fiber membrane bundle 1 and tubular box 2, and be situated between and undertaken by easy sliding property sheet 4 hollow fiber membrane bundle 1 is drawn in operation in the tubular box 2.And, from tubular box 2, controlling the part of easy sliding property sheet 4 reliably, and preventing to control the viewpoint that failure causes operation to stop fault and set out, tow drawn-back device 5 preferably has and carries out air in advance and attract and make the device that the part of easily sliding property sheet 4 is appeared.The viewpoint of hollow fiber membrane bundle 1 damage is also preferably disguised the guide body 7 of putting 3 side opening portions configuration funnel type at the tow U of tubular box 2 word during in addition from the inhibition operation.The part that can prevent hollow fiber membrane bundle 1 hangs over the end of tubular box 2 peristomes and damages hollow fiber membrane.
Below use Fig. 2～5 to illustrate in aforesaid device hollow fiber membrane bundle 1 packed into the program of tubular box 2.
At first, as shown in Figure 2,, draw together and cut into the state of specific length along a direction,, be configured in the concavity groove of tow pilot unit 8 with easy sliding property sheet 4 promptly as hollow fiber membrane bundle 1 with many with the hollow fiber membrane that is filled in the tubular box.
The sliding property sheet 4 of commute as long as flatness is good, and has certain tensile strength to get final product, not restriction especially, preferred resin film, cloth and silk etc.The resin molding of special preferably polyethylene, polypropylene, polyester etc., thickness is preferably the scope of 5～30 μ m.
The supply method of the sliding property sheet 4 of commute, as long as easy sliding property sheet 4 can be supplied to last configurable between hollow fiber membrane bundle 1 and tubular box 2 such position, promptly can supply between tow pilot unit 8 and the hollow fiber membrane bundle 1 and get final product, for example from can be continuously, efficient supplies with the viewpoint of easy sliding property sheet 4 well, preferred mode is columnar easy sliding property sheet is automatically cut into the length of regulation and is configured on the tow pilot unit 8.
In addition, supply with hollow fiber membrane bundle 1 and can manually supply with, but industrial preferred mode is to supply to automatically on the easy sliding property sheet 4 with conveyer belt, robot etc., thereby be placed in the concavity groove of tow pilot unit 8.
Next as shown in Figure 3, by putting the dull and stereotyped 3a and the 3b of 3 pressing parts as tow U word makeup, the middle part of hollow fiber membrane bundle 1 is pressed into to tubular box 2 directions, hollow fiber membrane bundle 1 is along with easy sliding property sheet 4 is bent to the U font together.At this moment, will be pressed into, make hollow fiber membrane bundle 1 and easily sliding property sheet 4 bend to the U font, and the part of this hollow fiber membrane bundle 1 and easily sliding property sheet 4 arrives described tubular box as the dull and stereotyped 3a and the 3b of pressing parts.
Then, shown in Fig. 4,5,, insert the peristome of the opposition side of hollow fiber membrane bundles 1 side, in the tubular box, control the part of easy sliding property sheet 4, thereby it is drawn in the tubular box 2 from tubular box 2 with the sheet handle sturcture 5a of tow drawn-back device 5.In a part of controlling easy sliding property sheet and when drawing in the tubular box, a dull and stereotyped 3b in the pressing parts is moved to the direction of drawing in of easy sliding property sheet.Here, play a role in order to make, preferably the film that the sheet handle sturcture 5a of tow drawn-back device 5 is controlled applies pulling force with drawing in efficient in operation.Therefore, to sheet handle sturcture 5a, preferably before beginning to move, dull and stereotyped 3b begins to draw in operation (that is, after beginning to utilize sheet handle sturcture 5a easily the property slided sheet is drawn in the tubular box, begin to make dull and stereotyped 3b to draw in direction and move) to easy sliding property sheet.In addition, from same viewpoint, also preferred tow drawn-back device 5 is drawn in the translational speed (promptly more than or equal to dull and stereotyped 3b to easy sliding property sheet draw in speed that direction move) of the speed of easy sliding property sheet more than or equal to dull and stereotyped 3b.In addition, at pressing parts is not to be made of 2 dull and stereotyped 3a and 3b, but under the situation about constituting by 1 plate-shaped member, preferably before beginning to move, this plate-shaped member begins to draw in the operation of sheet handle sturcture 5a, and preferred tow drawn-back device 5 is drawn in the translational speed of the speed of easy sliding property sheet more than or equal to this plate-shaped member.After the sheet handle sturcture 5a of tow drawn-back device 5 had controlled the part of easy sliding property sheet 4, the dull and stereotyped 3a of another of pressing parts withdrew from from tubular box 2.Like this, the hollow fiber membrane bundle 1 that bends to the U font is loaded in the tubular box 2 with the state that is coated by easy sliding property sheet 4.
Then, as required, remove easy sliding property sheet 4, the end of hollow fiber membrane bundle 1 is sealed, excises, and, under the moistening situation of hollow fiber membrane bundle, carry out processing such as drying, thereby finish hollow fiber membrane module.
Therefore, in the present embodiment, as mentioned above, when packing the tubular box into, on one side hollow fiber membrane bundle 1 and easily sliding property sheet 4 are bent to the U font to tubular box 2 with pressing parts, on one side the part with this hollow fiber membrane bundle 1 and easily sliding property sheet 4 is pressed into tubular box 2, controls the part of easy sliding property sheet 4 then and draws in the tubular box 2.By such operation hollow fiber membrane bundle 1 is drawn in the tubular box 2.In addition, at this moment, when drawing in easy sliding property sheet 4, pressing parts is moved to the direction of drawing in of easy sliding property sheet for auxiliary hollow fiber membrane Shu Yidong.That is, in the present embodiment, its formation is, produces the hollow fiber membrane bundle 1 required power of tubular box 2 of packing into by the operation of drawing in that acts on tow by sheet that is situated between basically, and it is auxiliary to utilize pressing parts to move simultaneously.Under the situation that the operation drawn in is only arranged, the sweep of hollow fiber membrane bundle does not produce damage, but as sliding between chankings and the hollow fiber membrane bundle, or sheet comes off from handle sturcture 5a, then the hollow fiber membrane bundle can not be pulled into the position of expectation.On the other hand, under the situation that push operation is only arranged, can make the hollow fiber membrane bundle move to the position of expectation, but only the power that is pressed into of the sweep by acting on the hollow fiber membrane bundle makes hollow fiber membrane Shu Yidong, so under the situation of the filling rate that improves hollow fiber membrane, may damage the sweep of hollow fiber membrane bundle.Therefore in the present embodiment, its formation is, produces the hollow fiber membrane bundle 1 required power of tubular box 2 of packing into by the operation of drawing in that acts on tow by sheet that is situated between basically, and it is auxiliary to utilize pressing parts to move simultaneously.Thus, can make the hollow fiber membrane bundle move to the position of expectation reliably, the makeup of tow U word can be put the power that is pressed into that 3 pressing parts 3b acts on the sweep of hollow fiber membrane bundle 1 simultaneously and suppress lessly, thereby can prevent broken line equivalent damage.
Then the beginning opportunity and the speed of each operation are narrated.Play a role in order to draw in efficient in operation, the sheet that must be controlled the sheet handle sturcture 5a of tow drawn-back device 5 applies pulling force.If dull and stereotyped 3b began to move before 5 operations of tow drawn-back device, then the distance of hollow fiber membrane bundle and handle sturcture 5a shortens and causes the sheet of the part of controlling lax, even begin to make the operation of tow drawn-back device also can not produce the power of drawing under this state sometimes.Therefore, the tow drawn-back device that preferably before dull and stereotyped 3b begins to move, brings into operation (that is, after beginning to utilize sheet handle sturcture 5a easily the property slided sheet is drawn in the tubular box, begin to make dull and stereotyped 3b to draw in direction and move) to easy sliding property sheet.In addition, if push operation faster than drawing in operation, then similarly causes the sheet of grip portion lax.Therefore, also preferred tow drawn-back device 5 is drawn in the translational speed (promptly more than or equal to dull and stereotyped 3b to easy sliding property sheet draw in speed that direction move) of the speed of easy sliding property sheet more than or equal to dull and stereotyped 3b.
In addition, as mentioned above, pressing parts can be the plate-shaped member of a slice, but is described as follows for the meaning that is made of two dull and stereotyped 3a and 3b.
When making hollow fiber membrane bundle 1 bend to the U font, broken line equivalent damage takes place in order to prevent bend, preferred not only carry out chamfered edge processing at the end face of pressing parts, the pressure of the contact-making surface that acts on hollow fiber membrane bundle 1 is reduced.Therefore, the area that is pressed into of preferably guaranteeing pressing parts is more than the certain value.On the other hand, when hollow fiber membrane being got one's things ready into box, if pressing parts enters in the tubular box 2, then hollow fiber membrane bundle 1 shared volume will reduce to be equivalent to the degree of the volume of pressing parts in tubular box 2.Therefore, hollow fiber membrane bundle 1 is pressed against tubular box inwall, so be easy to generate distortion, broken line equivalent damage.Can expect to make the easy effect that becomes of sliding, but under the situation of the higher goods of filling rate, because damage danger becomes high especially, so that preferred pressing parts enters the volume of part of box is less by easy sliding property sheet 4.Like this, the thickness of slab of preferred pressing parts is thicker for the requirement of satisfying the former, and opposite preferred thickness of slab is thinner for the requirement of satisfying the latter.Therefore, preferred tow U word makeup is put 3 pressing parts and is made of 2 dull and stereotyped 3a, 3b, when bending to the U font, make 2 and play a role simultaneously, thereby guarantee and the contact area of hollow fiber membrane bundle 1, when hollow fiber membrane being got one's things ready, only make 1 to play a role into the tubular box.
