As shown in Figure 1, formation of the wind deflector 15 in the width direction of the outer peripheral surface of delivery roll 5 has above-mentioned suction hole Region and the two sides in the region are provided with a pair, inflow of the wind from side is prevented or mitigated, to prevent from using recess portion from gathering The deformation etc. of the fine object of the product of 22 demouldings.There is no particular restriction for the material of wind deflector 15, but just making it have can be rigid to windproof Property viewpoint for, preferably metal or synthetic resin system, and the thickness with 0.5~10mm or so.

As disconnecting device 7, such as can be used without special restrictions in absorbent commodities such as menstrual hygiene cotton, diapers Device etc. of the prior art for the cutting of absorber non-individual body in manufacture.Disconnecting device 7 shown in FIG. 1 has including circumferential surface to be cut The smooth anvil roller 73 of the cutting roller 72 of breaking 71 and the circumferential surface for bearing cutoff tool.

Then, to using above-mentioned manufacturing device shown in FIG. 11 to be continuously manufactured by the method for absorber, suction i.e. of the invention One form of implementation of the manufacturing method of acceptor is illustrated.

The manufacturing method of this form of implementation in outer peripheral surface 21 there is the rotating cylinder 2 gathered with recess portion 22 to supply with state of dispersing Formed body material keeps formed body material product fine gathering with recess portion 22 and manufactures absorber.Specifically, present embodiment Manufacturing method includes: the fine step of product, supplies formed body material to the outer peripheral surface 21 of rotating cylinder 2 with state of dispersing, makes the formed body Material product is fine to be gathered with recess portion 22；The fine step of product again uses the above-mentioned periphery with above-mentioned rotating cylinder after the fine step of product The scraping roller 42 of face relative configuration scrapes the formed body material of superfluous area fibre, and making scraped formed body material, product is fine again.

Before stating the fine step of product on the implementation, make the space B being connected in rotating cylinder 2, the space in delivery roll 5 first Exhaust apparatus in E and vacuum tank 11 acts and becomes negative pressure.By will be set as negative pressure in space B, and generating in pipeline 4 will Absorber feedstock transportation to rotating cylinder 2 outer peripheral surface 21 air stream (vacuum pneumatic).In addition, rotating cylinder 2 and delivery roll 5 are rotated, Act suction conveyor 6.

When make the movement (not shown) of above-mentioned formed body material gatherer and by the formed body material as absorber raw material When supply is in pipeline 4, the formed body material with the air stream flowed in pipeline 4 become state of dispersing and to rotating cylinder 2 Outer peripheral surface 21 is supplied to, and product is fine to be gathered with recess portion 22 (product fibre step).Preferably, each of rotating cylinder 2 gathers with recess portion 22 During by being maintained in the space B of negative pressure, the porosity plate of bottom surface 22a, 23a with recess portion 22 are gathered via composition 27 and middle height the attraction in self-gravitation portion is carried out with porosity plate 25.By from respectively gathering with the porous material of recess portion 22 The attraction of pore makes to generate in pipeline 4 by the air stream of the outer peripheral surface of the feedstock transportation of absorber to rotating cylinder 2, make with the sky Air-flow and convey the raw material come and be deposited in and respectively gather in recess portion 22.

In the fine step of product, product fibre region PT in the inside of pipeline 4 will be dispersed state using a pair of of demarcation plate 41,41 Formed body material in a manner of overflowing surplus area fibre gathering with right to each other with a pair of of demarcation plate 41,41 in recess portion 22 The region answered.Specifically, as shown in Figure 1, Figure 2, Figure 4 shows, in the inside of pipeline 4, in the circumferential direction (direction 2X) along rotating cylinder 2 Both sides are provided with a pair of of demarcation plate 41,41, therefore, the formed body material for the state of dispersing are made intensively to be collected to gather and use recess portion The corresponding region between a pair of of demarcation plate 41,41 in 22.In manufacturing device 1, gathering in configuration with recess portion 22 The middle height of middle high recess portion 23 of middle section do not configure adjusting body 20 with the inner surface of porosity plate 25.Moreover, matching It sets except the internal surface configurations of the middle high porosity plate 27 for gathering the region with recess portion 22 in addition to porosity plate 25 have adjustment Body 20.Therefore, it is not suppressed via the middle high air stream with the attraction formed body material of porosity plate 25, via porosity plate 27 The air stream of formed body material is attracted to be suppressed.Therefore, in the present embodiment, the forming for making the state of dispersing can be more concentrated at Body material is collected on the middle high region locating for recess portion 23 between a pair of of demarcation plate 41,41.

In turn, in manufacturing device 1, the mutual opposite face of a pair of of demarcation plate 41,41 from the another side of pipeline 4 at The lateral rotating cylinder 2 of body material gatherer (not shown) tilts in such a way that mutual interval becomes narrow gradually, a pair of of demarcation plate 41, The mutual interval end 41a, 41a of 41 2 side of rotating cylinder and the width for gathering the middle high recess portion 23 with 22 middle section of recess portion Unanimously.Therefore, in the fine step of the product of present embodiment, the formed body material for the state of dispersing further can intensively be made to gather On the middle high region locating for recess portion 23 between a pair of of demarcation plate 41,41.Herein, when height recess portion 23 in cooperation When width (width in high portion in absorber 3 to be formed) sets the interval of end 41a, 41a of a pair of of demarcation plate 41,41, Grammes per square metre can be processed than high absorber.For example, when processing following absorbers shown in Fig. 10, it can be by making high thickness The width in the thinner part of width direction of (in high portion) 33 is consistent with end 41a, 41a of demarcation plate and processes grammes per square metre ratio more High absorber 3.

In addition, being configured with middle height at intervals in the circumferential direction (direction 2X) of rotating cylinder 2 in the middle high region locating for recess portion 23 With recess portion 23, therefore, the part configured with middle high recess portion 23 is deeper with recess portion 22 than gathering in addition to middle high recess portion 23.Cause This, as shown in Fig. 2, between with a pair of of demarcation plate 41,41 on corresponding region, in the circumferential direction (direction 2X) of rotating cylinder 2, Product it is fine with the height specific volume fibre of the formed body material configured with the corresponding region in the middle high part of recess portion 23 with remove in it is high Height with the formed body material in the corresponding region in part other than recess portion 23 is low.

Then, after the fine step of above-mentioned product, the formed body material of superfluous area fibre, the forming that will be scraped are scraped Product is fine in the both sides (long-pending fine step again) for gathering the part with the superfluous area fibre in recess portion 22 again for body material.In detail and Speech includes scraping to the product fibre region RPT again in downstream side from demarcation plate 41 in the inside of pipeline 4 as shown in Figure 1 and Figure 2 Roller 42 scrapes the formed body material of the excess quantity of product fibre；With scraping guide portion 43, configuration is from scraping roller 42 to rotating cylinder The position of 2 direction of rotation (direction R2) upstream side interval and the forming of state of dispersing that scraping roller 42 will be utilized to scrape Body material separates on rotating cylinder width direction (direction 2Y).Therefore, in the fine step of product again, as shown in figure 8, firstly, using scraping Roller 42 is taken to scrape the formed body material of superfluous area fibre.As described above, in the present embodiment, with a pair of of demarcation plate 41, 41 corresponding regions each other, in the circumferential direction (direction 2X) of rotating cylinder 2, product it is fine with configured with the middle high part for using recess portion 23 The height specific volume fibre of the formed body material in corresponding region with except it is middle it is high with recess portion 23 in addition to the corresponding region in part at The height of body material is low, therefore is scraped between with a pair of of demarcation plate 41,41 in corresponding region using scraping roller 42 , the height of the formed body material that product is fine it is relatively high and with except it is middle it is high with recess portion 23 in addition to the corresponding region in part in mistake Remain the formed body material of area fibre.That is, accumulating, in fine region corresponding between with a pair of of demarcation plate 41,41, product is fine Formed body material height it is relatively low and with configured with the middle high formed body material with the corresponding region in the part of recess portion 23 Material, is not easy to be scraped roller 42 and scrapes.

As shown in Figure 8, Figure 9, the formed body material scraped using scraping roller 42 is in the fibre region RPT of product again in pipeline 4 It is back to upstream side with the state of dispersing, is positioned away from using configuration from scraping roller 42 to the direction of rotation upstream side of rotating cylinder 2 Scraping guide portion 43 the formed body material for the state of dispersing is separated in the rotating cylinder width direction (direction 2Y) of rotating cylinder 2, then accumulate Fibre is in the both sides for gathering the part with the superfluous area fibre in recess portion 22.Gathering for upstream side recess portion is used in scraping roller 42 In 22, become the state that the formed body material of excess quantity is not yet scraped by scraping roller 42.Therefore, fine compared to superfluous area The formed body material of fibre is accumulated in the both sides of the circumferential direction (direction 2X) along rotating cylinder 2 of the part of superfluous area fibre in part It measures less, is not easy to hinder attraction because of the fine formed body material of product.Therefore, compared to gathering with superfluous in recess portion 22 The part of area fibre is easier to by the isolated formed body material of scraping guide portion 43, product fibre is gathering with the surplus in recess portion 22 again The both sides of the fine part of area.In addition, at this point, as shown in figure 4, by by with gather with the both sides of recess portion 22 it is corresponding Attract the opening portion 245 of adjustment plate 24 to be set as bigger than the opening portion 245 other than it, gathers and further pressed down with the both sides of recess portion 22 Body material is made to the obstruction of attraction, is easier to accumulate again by the isolated formed body material of scraping guide portion 43 and fine is gathering use The both sides of recess portion 22.

In manufacturing device 1, as shown in figure 9, towards the direction of rotation of rotating cylinder 2 when scraping guide portion 43 is with planar observation The top 431 of downstream side (scraping 42 side of roller) protrusion.Therefore, it can will be scraped by scraping roller 42 using scraping guide portion 43 The separation of formed body material, so as to product again it is fine it is nigh gather therefore will not be generated with the above-mentioned both sides in recess portion 22 The formed body material of the deviation, scraping to the fine region of product again that absorb body weight (grammes per square metre) does not overflow, so as to steadily make Make the absorber in high thickness (in high portion) with desired height and low thickness the portion periphery of high portion (in).In addition, due to After a part of the formed body material scraped by scraping roller 42 and the top 431 of scraping guide portion 43 are collided, to scraping guide portion 43 two sidewalls are separated, and therefore, for preventing paper pulp to be hooked on the viewpoint at top 431, top 431 is preferably acute angle or song Rate radius is 10mm small curved surface below.And then preferably following construction, that is, at top 431 with opposite with scraping roller 42 Towards fine air jet is arranged, alignment is scraped from scraping roller 42 and the formed body material injection dispersed to top 431 is empty Gas.Thereby, it is possible to be reliably prevented formed body material to be hooked on top 431.

In addition, in manufacturing device 1, as shown in figure 9, scraping guide portion 43 in planar observation its width from rotating cylinder 2 Direction of rotation (direction R2) upstream side downstream (431 side of top) is gone to be gradually reduced.Therefore, it can will be scraped by scraping roller 42 Formed body material use at the top of after 431 separation, be to reliably guided to close gather with the above-mentioned both sides in recess portion 22 And product is fine again, therefore, can not generate absorb the deviation of body weight (grammes per square metre), the paper pulp that has scraped to the fine region of product again will not overflow Out, the high thickness with desired height and the absorber in low thickness portion are more stably manufactured.

In addition, in manufacturing device 1, as shown in figure 8, having that hangs down from the top surface of the pipeline 4 to hang down in the inside of pipeline 4 Lower plate 44.Moreover, the product fibre region RPT again in the inside of the pipeline 4 separated by the plate 44 that hangs down configured with scraping roller 42 and is scraped Take guide portion 43.Therefore, it is scraped by scraping roller 42 and upstream side is back to the state of dispersing and then is separated by scraping guide portion 43 Formed body material, be back to position near the adjoining of upstream side using plate 44 is hung down.In this way, using recess portion compared to gathering The part of superfluous area fibre in 22, the formed body material scraped are easier to accumulate fine gathering with the surplus in recess portion 22 again The both sides of the fine part of area.Especially, in the present embodiment, as shown in figure 8, the plate 44 that hangs down is from the top surface of pipeline 4 Be formed as the R shape of arc-shaped to the direction of rotation (direction R2) of rotating cylinder 2, therefore, the formed body material scraped is easier quilt The plate 44 that hangs down guides and steadily product is fine again.

In addition, in manufacturing device 1, as shown in figure 8, scraping guide portion 43 is fixed on the plate 44 that hangs down.Therefore, being easy will be by The isolated formed body material of guide portion 43 is scraped along the curved surface for the plate 44 that hangs down and the side wall of scraping guide portion 43 being gradually reduced 43s is reliable and steadily the product fine adjoining in upstream side is gathered with the above-mentioned both sides in recess portion 22 again.

In addition, in manufacturing device 1, as shown in figure 9, the multiple protrusions 422 for constituting scraping roller 42 are only configured in roller main body It is corresponding with the fine formed body material of excess quantity in region between a pair of of ring flat-plate 29,29 of product in 421 outer peripheral surface Region.Specifically, scraping roller 42 is in planar observation, the region 421T configured with multiple protrusions 422 is configured at wide in rotating cylinder On degree direction (direction 2Y) with gather with the middle high position for using recess portion 23 (second area) Chong Die in recess portion 22, do not configure prominent 422 region is played to be configured on rotating cylinder width direction (direction 2Y) and gather with middle high with other than recess portion 23 in recess portion 22 The position of region (first area) overlapping.Therefore, it only can intensively scrape in gathering with recessed configured with middle high recess portion 23 The middle section surplus area fibre in portion 22 has the part of formed body material, and will not scrape again product fibre and gather in recess portion 22 The formed body material of above-mentioned both sides.That is, the scraping roller 42 of manufacturing device 1 becomes the formed body that will not be scraped other than necessary part The structure of material.For example, in the state of before product again is fine, product is fine to be gathering the formed body material with the both sides of recess portion 22 Few state correspondingly gathers shape of the part as superfluous area fibre in the middle section with recess portion 22 other than high portion State.Scrape that roller 42 scrapes the excess quantity and product is fine in the both sides of very few state gathered with recess portion 22 again, then product fibre this two The formed body material of side will not be scraped.Especially, then the fine formed body material of product due to not gathering being deposited in substantially Gathered backward with recess portion 22 and is therefore inhaled always compared to from product fibre region PT with the time for being attracted compression in recess portion 22 Impulse, which is reduced to gather, is easier bulging with the formed body material in recess portion 22, and becomes the state for being easy to be scraped, but according to upper Structure is stated, is deposited in that gather will not be by with the formed body materials of the both sides of recess portion 22 in product fibre region RPT again by product again is fine Roller 42 is scraped to scrape.Thereby, it is possible to do not generate absorb the deviation of body weight (grammes per square metre), scraped to the fine region of product again paper pulp not It can overflow, and more stably manufacture the high thickness with desired height and the absorber in low thickness portion.

In this way, only formed body material surplus area fibre is gathering the middle section for using recess portion 22 in the fine step of product again Part is scraped by scraping roller 42, and product fibre is being located at the very few of the direction of rotation upstream side of rotating cylinder 2 to the formed body material scraped again The both sides of area fibre gathered with recess portion 22, thereby, it is possible to the height of formed body material is adjusted to certain height.It is making It makes in device 1, is gathering the formed body material with recess portion 22, the formed body material that will be scraped by the way that the scraping scraping product of roller 42 is fine It is adjusted to the height of the height of the protrusion 422 to scraping roller 42, the outer surface 29a for being adjusted to ring flat-plate 29 in the present embodiment Degree.At this point, can be adjusted to appoint if changing the height (such as abrasion clearance (scuffing clearance)) of protrusion 422 The height (grammes per square metre) in high portion in meaning, but at this moment, the part other than middle high portion is (for example, the portion in circumferential direction other than high portion Point) height also change.Thus, for example in being only intended to adjust in the case where height (grammes per square metre) in high portion, as long as making middle high portion The depth of recess portion is deeper or makes gathering with recess portion more shallowly other than middle high portion.

In this way, gathering as shown in Figure 1, keeping formed body material product fine with after obtaining the fine object 32 of product in recess portion 22, in turn Rotate rotating cylinder 2.Then, when gather come the relative position of vacuum tank 11 with the fine object 32 of product in recess portion 22 when, by coming from The attraction of vacuum tank 11 becomes the state for being adsorbed on mesh belt 13, in this state, is transported to most connecing for delivery roll 5 and rotating cylinder 2 Near-end or its near.Then, the fine object 32 of product of the state of mesh belt 13 is adsorbed on and from the attraction of 5 side of delivery roll from gathering It is demoulded with recess portion 22, is transferred on delivery roll 5 together with mesh belt 13.

In Figure 10 shown with just from the fine object 32 of product of present embodiment gathered after being demoulded with recess portion 22.Product fibre object 32 is as schemed Shown in 10, with gather with deeper middle high recess portion 23 (second area) the corresponding part of the depth of the middle section of recess portion 22 at For higher-height high thickness 33, and except middle high with gathering with the corresponding part (first area) of recess portion 22 in addition to recess portion 23 As a lower height of low thickness portion 34.Specifically, the height of high thickness 33 is by configuring middle high on porosity plate 25 The thickness of spatial plate 26, the thickness of recess portion dividing plate 28 and ring flat-plate 29 thickness formed.In addition, low thickness portion 34 is by configuring The thickness of recess portion dividing plate 28 on porosity plate 27 and the thickness of ring flat-plate 29 are formed.

It is described in more detail, as shown in Figure 10, high thickness 33 is by by configuring middle high on porosity plate 25 The cyclic annular MD for dividing the clathrate intersection in region that forming member 261 surrounds of spatial plate 26 divide forming member 262 and CD The segmentation of forming member 263 (referring to Fig. 6) is divided, has and divides high thickness 331.In addition, low thickness portion 34 is being configured more It is in grid that the opening portion in addition to the opening portion of crosswise 281 of recess portion dividing plate 28 on permeability plate 27, which divides forming portion 284, The MD that shape intersects divides forming member 285 and CD divides the segmentation of forming member 286 (referring to Fig. 6), has segmentation low thickness portion 341。

In addition, in manufacturing device 1, in configuration in the middle high middle height for using recess portion 23 for gathering the middle section with recess portion 22 Adjusting body 20 is not configured with the inner surface of porosity plate 25, moreover, configuring in the collection in addition to middle high porosity plate 25 It is poly- to have adjusting body 20 with the internal surface configurations of the porosity plate 27 in the region of recess portion 22.In addition to this, in the fine region of product, pass through one 41,41 pairs of demarcation plate are gathered with the circumferential concentrated supply formed body material comprising middle high recess portion 23 in recess portion 22.Therefore, The high thickness 33 of the fine object 32 of product shown in Fig. 10 obtained using manufacturing device 1 becomes the fine amount of product of absorber raw material relatively More high grammes per square metre portions, low thickness portion 34 become the fine relatively small number of low grammes per square metre portion of amount of product of absorber raw material.In addition, product fibre object 32 The global of bottom surface become general planar using scraping roller 42.

As shown in Figure 1, the fine object 32 of product being transferred on delivery roll 5 is quilted on one side by while attraction from 5 side of delivery roll Conveying configures non-woven fabrics including cotton paper or liquid permeability on the suction conveyor 6 of the lower section of delivery roll 5 etc. to being directed into It is transmitted on clad sheet 37.Thereafter, as shown in Figure 1, by the both sides inflection along conveying direction of clad sheet 37, product fibre object 32 Upper and lower surface coated by clad sheet 37.Then, the fine object 32 of the product of the state coated by clad sheet 37 and clad sheet 37 are sharp together It is cut off with middle position of the cutting roller 72 of disconnecting device 7 between adjacent high thickness 33,33.In this way, obtaining The absorber 3 coated by clad sheet 37.

The absorber 3 for using manufacturing device 1 shown in FIG. 1 to obtain be comprising high thickness 33 and low thickness portion 34 and as The local different absorber of the height of the formed body material of absorber raw material.Use the product fibre for the absorber 3 that manufacturing device 1 obtains Uneven few, such absorber 3 becomes as absorbent commodities such as disposable diaper, menstrual hygiene cotton, incontinence protections The product of the preferred high-quality of absorber.In this way, manufacturing device 1 according to the present embodiment and the manufacturing method using it, energy Enough steadily manufactures have the absorber of the high thickness and low thickness portion of desired height.In addition, passing through above-mentioned adjusting body 20 Effect, high thickness 33 become relatively high grammes per square metre, and low thickness portion 34 becomes relatively low grammes per square metre.In this way, according to this reality It applies the manufacturing device 1 of mode and using its manufacturing method, can steadily manufacture high thickness with required grammes per square metre and low The absorber of thickness.

The present invention is not limited by above embodiment and above-mentioned form of implementation and can suitably be changed.
