Description

For shaping the conversion system of gluing diaper and trousers type diaper

Technical field

The disclosure relates to the conversion system for the manufacture of absorbent article, and relates more specifically to comprise the system for the production of a plurality of conversion production lines of gluing diaper and trousers type diaper.

Background technology

Disposable, reusable and durable product such as diaper, adult incontinence product, feminine hygiene tampon, sanitary towel, underwear, shirt, medicated underpants, swimsuit, robe, trousers, overcoat, glove, scarf, surgical drage, bib, blanket, thin slice, pillowcase etc. all can be manufactured on the high-speed transitions machining production line.This type of conversion production line can utilize based on fibroreticulate carrier, and no matter a lot of source materials are with the form of continuous fiber net or processed and/or be attached to described fleece to produce finished product on described carrier with the form of discrete patch.

Although the conversion production line can allow the absorbent article of high-speed production particular type, but some conversion production lines may not possess motility, this is because the variation for being adapted to produce the required production line of dissimilar product will be very consuming time and/or high so that be unpractical economically.For example, some conversion production lines be custom design and be built into the specific products in the narrower parameter of manufacture and operating condition scope.For example, the conversion production line can be custom-designed to only manufactures gluing diaper, and other conversion production line can be custom-designed to and only manufactures trousers type diaper.Therefore, the diaper that the conversion production line of this type of customization can be used to the production particular type is for example gluing or the trousers type, on some market, provides good coupling for business demand as possible.Yet the numerous differences that are designed to produce between the conversion production line of different product may provide the ability of multiple product supply to express unnecessary restriction on some markets to manufacturer.

May need to have independently conversion production line in the market Shang， manufacturer that all has consumption demand for gluing diaper and trousers type diaper, be custom-designed to separately and produce one of two kinds of products, this may need the process and the engineering development that double.Yet the consumption demand of these products one or both of may not be highly must be enough to be worth manufacturer to spend into original exploitation and maintain the independent translation machining production line of being devoted in these product types each.For example, if be not highly must be enough to be worth cost only to produce the cost of the conversion production line of trousers type diaper to the demand of trousers type diaper on particular market, manufacturer may determine not provide trousers type diaper on this market.On this type of market, producing these two kinds of products and therefore produce suitable blended product on identical conversion production line can provide the method for the most efficient and high performance-price ratio with this motility of meeting the need of market.

On some markets, when disposable gluing diaper starts bedpan training from being born to the baby for the baby.As the substitute of gluing diaper, the disposable pants type diaper can be desired and is applicable to be in the child's of bedpan training stage product.Yet in other cases,, the use of trousers type diaper can be from the age at the age early than usually being associated with the bedpan training, so trousers type diaper may be used to such an extent that similarly be more gluing diaper rather than training pants.A kind of difference between gluing diaper and trousers type diaper is that described two kinds of products are delivered to the mode of consumer from manufacturer, i.e. packing.Particularly, the general equal absorption base structure that comprises of gluing diaper and trousers type diaper, it has the permeable bodyside liner of outer covering piece, liquid and the absorbing structure of liquid impermeable.Yet, gluing diaper can not have around closed initial waist opening or leg opening before taking out from packing, and the absorption base structure of trousers type diaper and/or lateral plate (when existing) can be preliminary closure to form around initial waist opening and two leg openings.The percentage ratio of user of wearing diaper due to the user of the gluing diaper of preference and preference trousers jacket is different because of market, and therefore advantageously manufacturer has following motility: produce gluing diaper with the ratio of any expectation and the trousers jacket is worn diaper to meet the demand of market prospective on identical conversion production line.

Done some and attempted createing the conversion production line that can produce more than the diaper of a type, such as U.S. Patent Publication, 2007/0213678A1 is disclosed.Yet this type of conversion production line has represented only aggregation or the assembly of the different switching machining production line of the diaper that is designed to build particular type.When producing dissimilar diaper, these conversion production lines can utilize identical process and the machinery equipment of relative low number.Therefore, according to produced be that relatively numerous various process and the machine on this type of conversion production line connected or closed to the diaper of what type.Therefore, when producing dissimilar diaper, may not can use the conversion production line that comprises relatively numerous processes, this may cause excessive capital cost, needs a large amount of spaces, the exploitation that need to double, and need additional maintenance.

Therefore, still need to develop a kind of conversion system that comprises a plurality of conversion production lines, described conversion production line is designed to the diaper (for example trousers type diaper or gluing diaper) of production particular type, and utilize the identical process of basic number and machine to produce any in these two kinds of types of diapers, thereby obtain higher efficiency and lower overall cost simultaneously.

Adhesive type conversion equipment 300T is shown in Fig. 8 with the first configuration, and it is suitable for manufacturing gluing diaper 100T.As previously mentioned, the conversion equipment of this paper also can be designed in the second configuration, and wherein transformation mechanism is arranged to produce a plurality of trousers type diaper 100P.Therefore, more than second conversion that transformation mechanism produces the second number.For example, trousers type conversion equipment 300P is shown in Fig. 9 with the second configuration, and it is configured to produce such as above with respect to shown in Fig. 2,5 and 7 and described trousers type diaper 100P.As hereinafter more described in detail with respect to Fig. 8 and 9, in these two kinds of configurations, it is identical that the conversion of relatively large percentage ratio keeps.

As above, with respect to as described in Fig. 8, should be appreciated that shown in Fig. 9 and described conversion can be implemented from this paper paint and described different order by various.As shown in Figure 9, as trousers type conversion equipment 300P, during in the second configuration for the production of trousers type diaper 100P, top flat assembling process 1001, core assembling 1002 and the assembling of lower limb hoop and the conversion 2001 and 2002 be associated can be with above identical in conjunction with what shown in Fig. 8, gluing diaper configuration 300T discussed.In addition, the egative film shown in Fig. 9 assembling 1004, lower limb elastomeric element assembling 1005 and the conversion 2003 be associated and 2007 can with above in conjunction with Fig. 8, discuss identical.Therefore, with above be combined the process assembling 1001,1002 that Fig. 8 A and 8B discuss, 1003,1004 and 1005 conversions that are associated also can with the process assembling 1001,1002 shown in the trousers type diaper configuration 300P of Fig. 9,1003,1004 conversions that are associated with 1005 are identical.

Although a lot of in these processes and the conversion that is associated all can remain unchanged between the trousers type diaper configuration 300P shown in the gluing diaper configuration 300T shown in Fig. 8 and Fig. 9, have some difference.For example, in Fig. 9, front auricle assembling 1007T and touch-down zone assembling 1008T and the conversion 2005T be associated and 2006T are shown in broken lines, to indicate these assemblings and to transform, can be not used in trousers type diaper configuration.In some embodiment of conversion equipment 300P, without physically removing and 1007T from conversion equipment 300P, 1008T, the transformation mechanism that 2005T and 2006T are associated, but simply by their forbiddings, " closing " or walk around.Should be appreciated that in certain embodiments, can manufacture in configurations the conversion 2006T that utilize touch-down zone assembling 1008T and be associated at some trousers, for example, when manufacture has the trousers type diaper 100P of lateral plate of refastenable.

As shown in Figure 9, the trousers type conversion equipment 300P in second (trousers type diaper) configuration can comprise that lateral plate assembling process 1006P is to produce the lateral plate 112 and 114 shown in Fig. 2. Sheet 112 and 114 also can transform 2004P place and egative film substrate combination.Should be appreciated that lateral plate assembling process 1006P also can comprise various conversions.For example, lateral plate assembling process 1006P can comprise with above in conjunction with the described identical conversion of rear auricle assembling process 1006T shown in Fig. 8 and 8B.

As shown in FIG. 8 and 9, according to conversion equipment, be in first (gluing diaper) configuration or second (trousers type diaper) configuration, final forming process 1009 also can comprise the conversion that some are different.For example, when conversion equipment 300 is placed in the trousers type configuration shown in Fig. 9, the folding 2008T that transforms of the auricle shown in Fig. 8 is removed or forbids.Therefore, when the trousers type diaper 100P in Fig. 9 travels through final swivelization 2009, lateral plate 112 and 114 can stretch out from vertical side of the edge 128 and 130 side direction of base structure 102, shown in Fig. 2.In addition, as shown in Figure 9, trousers type diaper 100P is stood and the described identical folding conversion 2010 of the gluing diaper configuration in conjunction with in Fig. 8.Therefore, no matter be with gluing diaper configuration running or, with the running of trousers type diaper configuration, adhesive type conversion equipment 300T and trousers type conversion equipment 300P can utilize identical folding apparatus 302, all folding apparatus described above separately.Yet, when trousers type diaper 100P folded 2010, lateral plate 112 and 114 remains in the position extended laterally.

As shown in Figure 9, make folding trousers type diaper 100P stand additional the conversion, described additional conversion is not applied to gluing diaper 100T.Particularly, make folding trousers type diaper 100P stand lateral plate and connect conversion 2012, and can before marching to stacking conversion 2011, make them stand lateral plate turnover conversion 2013.

When folding trousers type diaper 100P transforms 2010 and advances and when pass lateral plate and connecting conversion 2012, the lateral plate 112 extended laterally is connected with another part of trousers type diaper 100P with 114 remote area 176 from folding.For example, the lateral plate shown in Fig. 2 112 can be connected with back waist region 118 at above-mentioned conversion 2004P place with 114 proximal end region 174.Therefore, the lateral plate of Fig. 9 connects conversion 2012 and can be configured to lateral plate 112 is connected with the front waist region 116 of diaper pants 100P with 114 remote area 176, shown in Fig. 5.

Should be appreciated that can implement lateral plate with various types of transformation mechanisms connects 2012.For example, twisting transporter shown in Figure 11 structure can be used to transmit in the vertical trousers type diaper 100P, and simultaneously crooked and folding lateral plate 112 with 114 so that remote area is connected with the front waist region 116 of base structure 102.As shown in figure 11, the base structure 100P of folding trousers type diaper 100T can deviate from folding rotating cylinder 306 transmission with the lower void apparatus 402 that joins the front waist region 116 of base structure in the vertical by the upper void apparatus 400 of the back waist region 118 that joins base structure 102 to.The first twisting void apparatus 404 can be laterally disposed on the relative both sides of upper void apparatus 400 and lower void apparatus 402 with the second twisting void apparatus 406.Particularly, the first and second twisting void apparatus can comprise movable surface, such as the endless belt of longitudinally MD twisting.Therefore, when trousers type diaper 100P advances in the vertical, the first twisting void apparatus can apply vacuum power to keep the first lateral plate 112, and the second twisting void apparatus can apply vacuum power to keep the second lateral plate 114.Therefore, when trousers type diaper 100P advances, lateral plate 112 is folded on front waist region 116 and by it and is placed to front waist region 116 and contacts with 114 remote area 176.Lateral plate 112 also can be connected with front waist region 116 with 114 remote area 176.As mentioned above, lateral plate can, by variety of way such as by refastenable ground such as heat, adhesive, mechanical fastener, binding agents, strippingly, or for good and all be connected with front waist region.

As shown in Figure 9, before marching to stacking conversion 2011, trousers type diaper 100P can connect conversion 2012 from lateral plate and march to lateral plate turnover conversion 2013.The switch-over processing method of this paper and equipment can comprise that various types of mechanisms are to carry out the lateral plate turnover conversion 2012 shown in Fig. 9 and hereinafter in conjunction with the lateral plate turnover that Figure 10 was discussed, to transform 2012.For example, lateral plate turns down the U.S. Patent application 13/051,241 that conversion 2012 can utilize name to be called " Methods and Apparatuses for Tucking Side Panels of Absorbent Articles " and be filed on March 18th, 2011; Be called " Methods and Apparatuses for Tucking Side Panels of Absorbent Articles " with name and be filed in the turnover method and apparatus described in the U.S. Patent application 13/051,231 on March 18th, 2011; And United States Patent (USP) 6,723,035 and 6,776, the turnover method and apparatus described in 316.

Fig. 7 shows diaper pants 100P, and it has the relative lateral plate 112 and 114 in base structure of being folded to 102.As shown in Figure 7, each lateral plate 112 and 114 some parts are inserted in the base structure 102 of diaper pants 100P, make the some parts of these lateral plates be arranged between the inner surface 132 and back waist region 118 of front waist region 116.In addition, lateral plate 112 and 114 also defines along the first longitudinal folding line 250 of the first lumbar region 116 with along the second longitudinal folding line 252 of the second lumbar region 118 to the insertion in base structure 102.

Figure 12-15 show a kind of example lateral plate turnover equipment 500, and it can be used to lateral plate 112 and 114 is folded in base structure 102.This equipment can comprise 500 first transporters 502, the second transporter 204.Each transporter 502 and 504 can comprise movable surface 506, and described surface can be the form that is wrapped in roller band on every side and is configured to circumferential collar.One or more movably foraminate vacuum transport belts that also can be constructed in these bands, described conveyer belt applies vacuum power to receive, to keep and/or to shift diaper pants 100P on base structure 102.Should be appreciated that described each transporter can comprise the transporter more than, for example, longitudinally arranged in series and/or along a plurality of transporters of laterally being arranged in parallel.In addition, one or more transporters also can be constructed to rotary drum or vacuum rotary drum.Transporter 202,204 and 205 is vertically advancing diaper pants 100P to transform the 2012 turnover districts that mean through general lateral plate turnover in Fig. 9 and 10 on MD, and wherein the lateral plate folding machine is pushed into lateral plate 112 and 114 in base structure 102.

Figure 12 shows the profile of diaper pants 100P and the first transporter 502 and the second transporter 504.As shown in Figure 5, the first void apparatus 502 be with 506 to comprise region of no pressure 514, described region of no pressure applies downward vacuum power on the outer surface 134 of the first lumbar region 116 of base structure 102.And the second void apparatus 504 be with 506 to comprise region of no pressure 514, described region of no pressure is to applying vacuum power upwards on the outer surface 134 of the second lumbar region 118 of base structure 102.Therefore, the relative power be applied on base structure 102 by region of no pressure 514 keeps separately the inner surface 132 of the first lumbar region 116 and the second lumbar region 118.In addition, lateral plate 112 is illustrated in Figure 12 with 114 in relative elongated and configuration that do not turn down.

As shown in figure 12, the region of no pressure 514 of the first transporter 502 and the second transporter 504 limits side direction or horizontal CD width separately, and described width can be less than the lateral width that the relative longitudinal edge 128 and 130 by base structure 102 limits.In addition, the side direction of region of no pressure 514 or laterally the CD width also can be less than the lateral width that the relative longitudinal edge by absorbent cores 142 limits.Yet, should be appreciated that region of no pressure can be configured to have different lateral width and can limit the lateral width that is greater than or less than painted lateral width.For example, some embodiment can comprise following region of no pressure, and described region of no pressure has the lateral width of the lateral width of the absorbent cores of being equal to or greater than and/or base structure.In addition, these transporters also can be configured to along laterally CD and/or vertical MD have the region of no pressure more than.

Along with diaper pants 100P travels through the turnover district in the vertical, the relative vacuum power applied with the second transporter 504 by the first transporter 502 can continue to keep base structure or can remove from base structure.And lateral plate folding machine 516 is pushed into lateral plate 112 and 114 in base structure 102, for example, as shown in figure 13.Along with lateral plate 112 and 114 is pushed in base structure 102, the inner surface 132 of the first lumbar region 116 and the second lumbar region 118 can be towards moving each other. Lateral plate 112 and 114 is folded in base structure 102 and also in base structure 102, has produced longitudinal folding line 250 and 252.In the configuration shown in Figure 13, longitudinal folding line 250 and 252 also can overlap with the vertical side of the edge of absorbent cores 142 and can be limited by described vertical side of the edge.Should be appreciated that longitudinal folding line 250 and 252 can produce in various position according to specific turnover method and configuration.For example, in certain embodiments, longitudinal folding line can be corresponding to the lateral side edges of region of no pressure.In certain embodiments, lateral plate can not exclusively be turned down in base structure, and therefore, longitudinal folding line can limit along the length of lateral plate.
