Channel 4 extends to rotating cylinder 2 from aftermentioned fibrous material supply unit 7, and the opening covering in the downstream side in channel 4 is located at Maintain into the outer peripheral surface 21 of the space A and B of the rotating cylinder 2 of negative pressure.As shown in Figure 1, channel 4 have formed top surface top plate 41, It forms the bottom plate 42 of bottom surface and forms the two sidewalls 43,44 of two sides.Pass through the work of the extraction fan (not shown) of rotating cylinder 2 Make, in the space surrounded by the top plate 41 in channel 4, bottom plate 42 and two sidewalls 43,44, generates the outer peripheral surface 21 to rotating cylinder 2 The air stream of the raw material of circulation absorber.

In product fibre device 1A, the top plate 41 in channel 4 such as shown in Fig. 2 (a), Fig. 2 (b), push up by the upstream side by being located at upstream side Plate portion 411 and positioned at downstream side downstream side top plate portion 412 constitute.The bottom plate 42 in channel 4 is same, by being located at the upper of upstream side It swims side base plate 421 and the downstream side base plate 422 positioned at downstream side is constituted.Upstream side top plate portion 411 and upstream side base plate 421 width downstream goes to become narrow gradually from upstream side.Downstream side top plate portion 412 and the width of downstream side base plate 422 from Upstream side is downstream gone to be certain.Downstream side top plate portion 412 and the width of downstream side base plate 422 be located at upstream side top plate The width at portion 411 and the position near downstream side of upstream side base plate 421 is identical width.

The top plate 41 in channel 4 and interval such as Fig. 2 (a), Fig. 2 (b) of bottom plate 42 are shown, upstream side top plate portion 411 and upstream Interval between side base plate 421 is configured to centainly, and the interval of downstream side top plate portion 412 and downstream side base plate 422 is from upstream Side top plate portion 411 and upstream side base plate 421 go gradually to broaden to the outer peripheral surface 21 of rotating cylinder 2.The two sidewalls 43,44 in channel 4 Along by constituting in the above described manner upstream side top plate portion 411 and the both side edges of top plate 41 that constitute of downstream side top plate portion 412 and The both side edges for the bottom plate 42 being made of upstream side base plate 421 and downstream side base plate 422 configure.

As shown in Figure 1, Figure 2 shown in (a), the top plate 41 in channel 4 configures the polymerization that absorbent particles 32 are supplied in directed walk 4 Object diffusion tube 8.Specifically, polymer dispersed pipe 8 is configured at the end for constituting the downstream side of upstream side top plate portion 411 of top plate 41 Portion.Moreover, polymer dispersed pipe 8 configures in such a way that its lower end is located at the end of the upstream side of aftermentioned partition 45.

The channel 4 of top plate 41, bottom plate 42 and two sidewalls 43,44 with above-mentioned shape such as Fig. 2 (c) is shown, logical at this The most upstream that the area of section of the flow path in the dispersion zone of absorbent particles 32 forms than being located at the channel 4 is spread in road 4 Flow path area of section and the flow path positioned at the most downstream in the channel 4 area of section it is small.Here, " dispersion zone " refer to from Position configured with the polymer dispersed pipe 8 for spreading absorbent particles 32 is to the upstream side or the model with some degree is removed in downstream side The region enclosed.Specifically, channel 4 as shown in Fig. 2 (a)~Fig. 2 (c), is dissipated in the fine device 1A of product with polymer dispersed pipe 8 The area of section of the flow path surrounded by top plate 41, bottom plate 42 and two sidewalls 43,44 in the dispersion zone of cloth absorbent particles 32 Formed than the top plate 41, bottom plate 42 and two sidewalls by being located most closely to the upstream end thereof in the channel 4 of fibrous material supply unit 7 43, top plate 41, the bottom plate of the downstream end of the area of section and channel 4 by being located most closely to rotating cylinder 2 of 44 flow paths surrounded 42 and two sidewalls 43,44 surround flow path area of section it is small.More specifically, in the channel 4 of the fine device 1A of product, top plate 41 The width of the upstream side base plate 421 of upstream side top plate portion 411 and bottom plate 42 downstream goes to become narrow gradually from upstream side, because This, in upstream side top plate portion 411 and upstream side base plate 421, by the flow path of top plate 41, bottom plate 42 and two sidewalls 43,44 encirclement Area of section downstream go to gradually become smaller from upstream side.In addition, in the channel 4 of product fibre device 1A, the downstream side of top plate 41 The interval of top plate portion 412 and the downstream side base plate 422 of bottom plate 42 is downstream gone gradually to broaden from upstream side, therefore downstream side In top plate portion 412 and downstream side base plate 422, by the area of section for the flow path that top plate 41, bottom plate 42 and two sidewalls 43,44 surround It downstream goes to become larger from upstream side.Therefore, using the downstream side for being configured at upstream side top plate portion 411 end polymerization The area of section that object diffusion tube 8 spreads the flow path in the dispersion zone of absorbent particles 32 forms relatively small.The dispersion zone In domain, the area of section of the above-mentioned flow path of the end of the upstream side of the lower end of preferred polymers diffusion tube 8 or aftermentioned partition 45 Formed minimum.

Channel 4 is such as shown in Fig. 2 (a), configures in the fine device 1A of product restricted to the absorbent particles 32 supplied inside it Flow direction partition 45.Specifically, partition 45 throughout channel 4 two sidewalls 43,44 from upstream side top plate portion 411 under The boundary part for swimming side top plate portion 412 extends to rotating cylinder 2.More specifically, partition 45 to divide rotating cylinder 2 space A and The front end of the plate of space B extends.It is configured with partition 45 in the inside in channel 4, limits the flowing side of absorbent particles 32 as a result, To, when only make fibrous material 31 circulate when, be branched off into circulation fibrous material 31 and absorbent particles 32 flowing.

As shown in Fig. 1 and Fig. 2 (a), the downstream side of the position in the channel 4 of pressing belt 5 and rotating cylinder 2 is adjacent and along rotation The outer peripheral surface 21 of cylinder 2 configures, and is set to the negative pressure or zero pressure (atmospheric pressure) weaker than the space B of rotating cylinder 2 along being located at The outer peripheral surface 21 of space C, D configure.Pressing belt 5 is the band of cricoid gas permeability or non-breathable, is set up on roller 51 and roller 52, Gearing rotation is carried out together with the rotation of rotating cylinder 2.In addition, in the case where pressing belt 5 is the band of gas permeability, preferably actually On pass through the raw material in accumulation recess portion 22 band.Using pressing belt 5, even if the pressure of space C~E is set to atmosphere The fine object of product can be also held in accumulation recess portion 22 by pressure, until accumulation is transferred to vacuum with the fine object of the product in recess portion 22 On conveyer 6.

As shown in Fig. 1 and Fig. 2 (a), suction conveyor 6 is configured at the lower section of rotating cylinder 2, and configures in rotating cylinder 2 Positioned at the outer peripheral surface 21 for the space E for being set to weak positive pressure or zero pressure (atmospheric pressure).Suction conveyor 6 includes: to be set up in drive The cricoid gas-permeable strip 63 of dynamic roller 61 and driven voller 62,62；It is configured at and the sky positioned at rotating cylinder 2 with gas-permeable strip 63 is clipped Between E the opposite position of outer peripheral surface 21 vacuum tank 64.It imports on suction conveyor 6 by cotton paper or the non-woven fabrics of liquid permeability etc. The clad sheet 34 of composition.

As shown in Figure 1, fibrous material supply unit 7 is the fibrous material 31 to the supply of channel 4 as the raw material of absorber Part.Fibrous material supply unit 7 has fiber uncoiling machine 71.By the way that the blank 30 of the sheet of fibrous material 31 is imported fiber uncoiling machine 71, Carry out defibering blank 30, and the fibrous material 31 after defibering is supplied to the flow path in channel 4.

Then, illustrate the method for continuously manufacturing absorber using above-mentioned product fibre device 1A.

Firstly, the extraction fan progress work (not shown) for connecting space A, B and vacuum tank 64 in rotating cylinder 2 respectively Make, makes to become negative pressure in space A, B and vacuum tank 64 in rotating cylinder 2.By making to become negative pressure in space A, B, in channel 4 Generate the air stream (evacuated air) for conveying the raw material of absorber to the outer peripheral surface 21 of rotating cylinder 2.In addition, revolving rotating cylinder 2 Turn, acts pressing belt 5.

Then, so that the fiber uncoiling machine 71 of fibrous material supply unit 7 is worked, the blank of the sheet of fibrous material 31 is solved Fibre, the flow path fibrous material 31 after defibering being supplied in channel 4.In addition, utilizing the polymerization for the top plate 41 for being configured at channel 4 Object diffusion tube 8, Xiang Tongdao 4 is interior to supply absorbent particles 32.

Here, as shown in Fig. 2 (c), for channel 4, absorbent particles 32 are spread into the channel 4 as above-mentioned Dispersion zone in flow path area of section formed than be located at the channel 4 most upstream flow path area of section and be located at The area of section of the flow path of the most downstream in the channel 4 is small.Therefore, the stream of the fibrous material 31 after the defibering supplied in Xiang Tongdao 4 Move the undergauge in the dispersion zone for spreading absorbent particles 32 with polymer dispersed pipe 8.Moreover, in dispersion zone, after undergauge Fibrous material 31 effectively mixed with polymer, the fiber then as the flowing extended to the most downstream in channel 4, after undergauge The flowing of material 31 extends to the thickness direction whole region between the top plate 41 in channel 4 and bottom plate 42.At this point, in dispersion zone The absorbent particles 32 spread are effectively mixed with fibrous material, therefore as the flowing of fibrous material 31 is spread, not only fine Material 31 is tieed up, the absorbent particles 32 of 31 weight of weight ratio fibrous material are also easy to diffuse in channel 4 whole.That is, fibrous material 31 absorbent particles 32 dispersion zone undergauge, fibrous material 31 and absorbent particles 32 effectively mix (winding), as a result, Specific gravity is heavier to be not easy as the absorbent particles 32 of air stream can be to be also easy to air stream by light specific gravity and in shape Fibrous material 31 assist form be uniformly dispersed.In the especially fine device 1A of product, the upstream side top plate portion 411 in channel 4 And upstream side base plate 421, from top plate 41, bottom plate 42 and two sidewalls 43,44 surround flow path area of section from upstream side to Downstream side is gone to gradually become smaller, and therefore, the flowing of the fibrous material 31 after the defibering supplied in Xiang Tongdao 4 is by polymer dispersed pipe It is easy to undergauge in the dispersion zone of 8 distribution absorbent particles 32.In addition, in product fibre device 1A, the downstream side top plate portion in channel 4 412 and downstream side base plate 422, the area of section of the flow path surrounded by top plate 41, bottom plate 42 and two sidewalls 43,44 is from upstream side It downstream goes to become larger, therefore, the thickness direction that the flowing of the fibrous material 31 after undergauge is readily extended to channel 4 is entire Region, the absorbent particles 32 of distribution are easier to spread with the flowing of fibrous material 31, fibrous material 31 and absorbent particles 32 are easier to diffuse to entirety in channel 4.In addition, as the dispersion zone for making fibrous material 31 concentrate on absorbent particles 32 Other methods, there are as below methods for tool, that is, does not make flow path undergauge, the shape in channel 4 is set as rectilinear form, and make to be located at channel 4 Most upstream flow path area of section it is identical as the area of section of the flow path of dispersion zone, but in this case, need to reduce Fibrous material sheet material width (blank width), and the speed to fiber uncoiling machine conveying sheet is further speeded up, and worry to cause undulation degree The defibering of material 31 is insufficient.Also, when reducing piece width (blank width), the depletion rate of blank is accelerated, and replacement frequency increases, Therefore, the problem of increasing there is also production loss.It is therefore preferable that piece width (blank width) is wider, it is therefore preferable that being located at channel The area of section of the flow path of 4 most upstream is most wide.

The absorbent particles 32 spread in dispersion zone are spread with the flowing of fibrous material 31, fibrous material 31 and suction The property received 32 one side of particle integral extension into channel 4, when being supplied on one side to the accumulation of the outer peripheral surface 21 of rotating cylinder 2 with recess portion 22, On thickness direction of the accumulation with recess portion 22, absorbent particles 32 are easy to be homogeneously dispersed in fibrous material 31 and absorbent particles In the fine object 33 of 32 product.

In addition, as shown in Fig. 2 (a), partition 45 is configured in channel 4 in product fibre device 1A.Therefore, with rotating cylinder 2 Upstream side the corresponding region space A in, be easily formed the filter layer being made of fibrous material 31.In addition, with space A's In the corresponding region of space B of the rotating cylinder 2 in downstream side, be easily formed be made of fibrous material 31 and absorbent particles 32 it is mixed Close layer.In this way, the absorbent particles 32 spread are easy to the stream with fibrous material 31 in the channel 4 of the top of partition 45 It moves and spreads, fibrous material 31 and absorbent particles 32 are easy extension.Here, filter layer is for preventing absorbent particles 32 stifled Fill in the layer of the accumulation net pore of 22 bottom of recess portion.In addition, rotating cylinder 2 has the regulating mechanism for adjusting attraction, thus, for example By adjusting and the balance of the attraction in the corresponding region of space B and the attraction in region corresponding with space A, in partition 45 In the channel 4 of top, fibrous material 31 and absorbent particles 32 can more easily extend.More specifically, for example, space A Attraction it is too strong relative to the attraction of space B when, excessively form the filter layer being made of fibrous material 31, and spreading The mixed fibrous material 31 of the absorbent particles 32 that region is spread reduces corresponding amount, therefore, not mixed with fibrous material 31 The absorbent particles 32 of conjunction are not dispersed, and agglomerate and exist in the fine object 33 of product.In this case, it is adjusted using regulating mechanism And the balance of the attraction of the attraction and region corresponding with space A in the corresponding region of space B, thus inhibits excessive filtering The formation of layer, can be allocated in dispersion zone for the fibrous material 31 for mixing required full amount with absorbent particles 32, As a result, the absorbent particles 32 spread are reliably mixed with fibrous material 31, and in the channel 4 of the top of partition 45, energy Enough it is easy to expansion fiber material 31 and absorbent particles 32.

As more than, make the raw material product of absorber fine in accumulation recess portion 22 and after obtaining the fine object 33 of product, as shown in Figure 1, Rotating cylinder 2 is further rotated, the fine object 33 of product is pressed in accumulation in recess portion 22 using pressing belt 5 on one side, is transported on one side On suction conveyor 6.Moreover, when building up the relative position with the fine arrival of object 33 vacuum tank 64 of product in recess portion 22, by coming from The attraction of vacuum tank 64, from accumulation with recess portion 22 demould, and to import suction conveyor 6 on by cotton paper or the nonwoven of liquid permeability It is shifted on the clad sheet 34 of the compositions such as cloth.

Then, it will turn back along the both sides of the conveying direction of clad sheet 34, by the upper and lower surface of the fine object 33 of product by cored Piece 34 coats.Moreover, the fine object 33 of the product of the state coated by clad sheet 34 is cut off device (not shown) together with clad sheet 34 Cutting mechanism cutting.In this way, being continuously available the absorber 3 that the fine object 33 of product is coated by clad sheet 34.

Using the fine object 33 of product of the obtained absorber 3 of product fibre device 1A as shown in figure 3, not only in the width side of the fine object 33 of product Upwards, and in a thickness direction absorbent particles 32 have also been uniformly dispersed.Therefore, the absorption obtained using product fibre device 1A Body 3 is not likely to produce gel blockage in use, becomes and is suitable as the suction such as disposable diaper, sanitary napkin, incontinence protection The absorber of the high quality of absorber used in the property received article.In this way, according to the fine device of product for having used first embodiment The manufacturing method of 1A can be manufactured steadily not only in the width direction of the fine object 33 of product, but also also uniform in a thickness direction Ground is dispersed with the absorber 3 of absorbent particles 32.

Then, product fibre device 1B~1E of the of the invention second~the 5th embodiment is illustrated.About second~ The fine device 1B~1E of the product of 5th embodiment, mainly says the point different from the product fibre device 1A of first embodiment It is bright, identical symbol is marked to identical point and is omitted the description.For not specifically mentioned point, appropriate application is implemented with first The relevant explanation of the fine device 1A of the product of mode.In addition, the effect of the fine device 1B~1E of product about the second~the 5th embodiment, The point different from the effect of the fine device 1A of the product of first embodiment is illustrated, the point being not particularly illustrated and the fine device of product The effect of 1A is identical, and the explanation of the effect of the suitably fine device 1A of application product.

Shown in product fibre device 1A such as Fig. 4 (a), Fig. 4 (b) of above-mentioned first embodiment, according to fibrous material supply unit 7 Fiber uncoiling machine 71 characteristic, 42 side of bottom plate (lower section) on the thickness direction between the top plate 41 in channel 4 and bottom plate 42 has When it is more by the quantitative change of the fibrous material 31 of defibering.In this way, when the amount of fibrous material 31 is when lower section becomes more, product fibre device 1A In, as shown in Fig. 4 (a), excessively formed in region corresponding with the space A of the upstream side of rotating cylinder 2 by fibrous material sometimes 31 filter layers constituted.The fine object 33 of the product of the absorber 3 obtained under this situation fibrous material 31 as shown in figure 5, be only made of The filter layer of fibrous material 31 excessively formed below thickness direction, with the absorbent particles spread in dispersion zone 32 mixed fibrous materials 31 tail off, therefore absorbent particles 32 not mixed with fibrous material 31 are not dispersed, and in product It agglomerates and exists in fine object 33.Assuming that even if adjusting stronger than the attraction of space A by the attraction of space B, above partition 45 Dispersion zone in the heavier absorbent particles 32 of specific gravity the flowing of the fibrous material 31 lighter with specific gravity does not mix yet, because This, sometimes cannot fully dispersed absorbent particles 32.In order to increase the amount in the fibrous material 31 of dispersion zone circulation, make fiber Material 31 concentrates on diffusion tube front end and nearby is easier to mix with absorbent particles 32, second embodiment described below The product fibre device 1E of the product fibre device embodiment of 1B~the 5th is effective.
