Basically, reel up-coiler or 1 expression of up-coiler entirety by reference numeral, it comprises take up roll 3.Along feed path by the web N(of feed particularly, nonwoven webs for example) to reel around take up roll, feed path is defined by a plurality of rollers 5 of take up roll 3 upstreams.Take up roll 3 is driven and rotating on direction shown in arrow f3, with towards just in the reel B of moulding feed web.Reel B(is referring to Fig. 1 and Fig. 2) reel around winding core (its entirety by reference numeral 10 expressions).Winding core is resisted against on a pair of guide 11 of basic horizontal with known manner, and guide is arranged on up-coiler sidepiece 13.The surface of reel B keeps pressing take up roll 3 with known manner, and like this, reel carries thereby batch from described take up roll 3 web or the nonwoven webs N that comes because the counteraction of the friction of described take up roll 3 keeps rotation.
A pair of guide 15 is arranged on guide 11 tops, and this has formed idle winding core 10(to guide 15, and it is just waiting for the wrapping range that is fed to up-coiler 1) reservoir.Reference numeral 10X represents to be positioned at the winding core of take up roll 3 tops, and this winding core is prepared just replacing winding core 10 after the reel B of moulding has completed moulding around winding core 10.Just began to contact before take up roll 3 is by the web of feed or nonwoven webs N at winding core 10X, for example the gear by this winding core 10X end can make this winding core 10X rotate with known manner.
Be provided with the guide 17 that is associated with take up roll 3, this guide mainly comprises C shape profile, this profile first end 17X(Fig. 3 and 4 on up-coiler one side) extend to the end 17Y on opposite side.This C shape guide 17 has opening, and in the part of described opening between described first end 17X and curve 17Z, up, described crooked position is on up-coiler 1, opposite with a described first end place side side.This guide and curve 17Z are as one man crooked, make end end 17Y have down guide opening.
Be provided with band or ribbon S in guide 17, band or ribbon are for example made by plastic material, Paper or cardboard, and can reinforce by synthetic resin.Band or ribbon S are used for tearing or disconnecting nonwoven webs N in the described mode in back.Be provided with drg 18 near first end 17X, this drg applies brake action on band S.Hereinafter, this band S is referred to as " tear-strap ", thereby because itself and winding core 10,10X cooperatively interact and cause the disconnection of web by tearing nonwoven webs N.
Tear-strap S is preferably slightly long than guide 17; This tear-strap is inserted in described guide, and the end of an end SX who makes this tear-strap from the end 17Y of guide 17 towards winding core 10X partly extends.Thereby the end SX of tear-strap S is near anchor fitting, and this anchor fitting is used for tear-strap S is fixed to the winding core 10X that just is in wait state above take up roll 3.Fig. 1 to 4 has schematically shown the anchor fitting that represents with Reference numeral 21.The below describes the embodiment of described anchor fitting with reference to the accompanying drawing of back.
As shown in Fig. 3 and 4, if the end SX of tear-strap is inserted in anchor fitting and with winding core 10X and engages, will drive tear-strap S when winding core rotates and rotate together on coiling direction, and under the tension force effect that imposes on tear-strap, tear-strap be pulled out from guide 17.Being arranged near the 17X of end drg 18 bears tear-strap S to be enough to make tear-strap S to become the tension force of arranging (Fig. 4) around winding core 10X curl.Because tear-strap is positioned at guide 17 (especially as illustrated in fig. 1 and 2), therefore, around tear-strap S is pulled and is wound on spirally winding core 10X, and this tear-strap remains in the process of the state of being tightened up by the brake system 18 that is in first end 17X place, and tear-strap S is positioned at the below of nonwoven webs N.This causes nonwoven webs N to begin and continue be torn gradually or disconnect towards the opposite end from winding core 10X, end that be connected with described anchor fitting, thereby formed the head of web N, the head of web is along stretching around the line of the helix line inclination certain angle of winding core 10X formation with respect to tear-strap S.
Tear-strap S is except realizing making web N disconnects, and also the edge of the described head that forms like this will be connected to new winding core 10X gradually.In case complete aforesaid operations, just continue to reel with known manner, and winding core 10X is reduced to the another location from position shown in Fig. 1 and 2, in this another position, the end of described winding core is resisted against on the guide 11 of up-coiler 1.The end of the winding core that stretches out from the reel that is forming engages with a pair of carriage (not shown), and the reel that described a pair of carriage will just reeled around winding core pushes against the surface of take up roll 3, thereby makes winding core and reel continue rotation, thus coiling web N.
Even web N(is as in the situation that nonwoven webs) in be impregnated with such as surfactant or be impregnated with the materials such as other additives that use in the web production process, the anchor fitting 21 that is arranged on each winding core 10,10X also can adhere to the end SX of tear-strap S or be fixed on winding core reliably.If adopt other fixing meanss, for example adopt adhesive tape, because these additives can stain the winding core surface, thereby can hinder tear-strap S to be fixed to winding core 10,10X.In certain embodiments, also keep the end of tear-strap S with anchor fitting 21, so as not to tear-strap material webs around during and wave during subsequently any other course of processing (uncoiling that is used for rewinding).
Can adopt the whole bag of tricks to make anchor fitting 21.Fig. 5 and 6 shows an embodiment of anchor fitting.
Fig. 5 and 6 has specifically illustrated the vertical section of the end of winding core 10,10X, and described end and mechanical fastening system 21 link.In this embodiment, winding core 10,10X comprise vertical base portion 31, and this vertical base portion comprises vertical wall 33(, and it for example is essentially cylindrical), vertically the outside face of wall has defined nonwoven webs N surface wound thereon.
Be provided with pin 35 in the end of winding core 10,10X and in vertical wall 33 inboards of vertical base portion 31, described pin is fixed to vertical base portion 31 of winding core 10,10X coaxially, and the axis of pin stretches along A-A.Pin 35 also is stretched over the outside of vertical wall 33, sleeve 37 vacant on pin (idly).Sleeve 37 is supported on the diameter of pin 35 narrower zone in vacant mode by bearing 38.Be positioned at outside sleeve 37 by the wheel 39 that is keyed onto on pin 35, this is taken turns and can be used for just driving the winding core rotation in winding core 10,10X contact before the web N that take up roll 3 is reeled, and these are all realized in substantially known mode.
Be provided with the sliding part that is essentially dish type (its integral body represents with mark 45) that cooperatively interacts with permanent magnet 43, sliding part 45 by bearing (as, plain bearing) be slidably mounted on pin 35, this bearing schematically represents with mark 47, and bearing is housed in lining 49 with pin 35 coaxial arrangement.
In certain embodiments, sliding part 45 comprises two parts.More specifically, in the illustrated embodiment, sliding part 45 has that the first disc-shaped element 51, the first disc-shaped elements 51 are integral with lining 49 or the part of the part that formation is identical with lining 49.Advantageously, this first disc-shaped element can comprise ring 53, but this ring is made by the material of elastic compression such as plastic material or rubber, and this ring cooperatively interacts with the ring-shaped end edge 33B of cylindrical vertical wall 33 in the following manner, and this cylindrical vertical wall has formed vertical base portion 31 of winding core 10.The elasticity of material under compression that forms ring 53 has prevented that the pressure between edge 33B and the first disc-shaped element 51 from cutting off or disconnecting tear-strap S between the used life of anchor fitting 21.
The second portion of sliding part 45 is supported on the first disc-shaped element 51 by bearing 55.Shown in example in, this second portion also is essentially dish type, hereinafter it is expressed as actuation element 57.Described the first disc-shaped element 51 and actuation element 57 are connected to each other in the axial direction, but due to the effect of bearing 55, they are not coupled aspect torsion mutually, thereby, the first disc-shaped element 51 can rotate freely around the axis A-A of winding core 10, and is not subjected to the constraint of actuation element 57.
One holding device entirety by reference numeral 61 expressions, valuably, holding device can be associated with sliding part 45, thereby, in the following mode of being explained, especially under condition of service, the edge 33B that holding device keeps near vertical wall 33 sliding part 45, as shown in Figure 6.
In an illustrated embodiment, holding device 61 comprises and vertical wall 33 all-in-one-piece housings 63, and vertically wall has formed vertical base portion of winding core 31.In described housing, bar 65 slides and an end 65A of bar is connected to sliding part 45, more precisely, is connected on the first disc-shaped element 51 of sliding part 45.The opposite end of bar 65 has baffle plate 67, and baffle plate is set to make helical compression elastic element 69 to keep preload condition between the bottom 63A of baffle plate 67 and housing 63.When sliding part 45 was not connected to magnet 43, under the thrust that is applied by Compress Spring 69, sliding part kept near ring edge 33B.In certain embodiments, the axis A-A around winding core can be furnished with a plurality of holding devices 61.Due to the impact of the given shape with holding device 61 and holding device, the first disc-shaped element 51 is coupled with winding core with reversing.Thereby in this embodiment, during around himself axis A-A rotation, the first disc-shaped element 51 also rotates with winding core when winding core 10,10X.
Importantly, note that can be different from be used to the morphosis that sliding part 45 is kept nestle up the holding device of edge 33B on winding core 10,10X shown in morphosis.For example, can be provided with the radial engagement member, in the recess on the lateral surface of this radial engagement component elasticity ground insertion lining 49.
In structure shown in Figure 5, sliding part 45 is kept by permanent magnet 43, thereby permanent magnet plays the effect of the second holding device, and its effect is opposite with the first holding device 61.In this structure, sliding part 45(more precisely, and its all-in-one-piece ring 53) and vertically have space D between the edge 33B of wall 33, this spacing is greater than the width of tear-strap S.Tear-strap S also can insert with 90 ° of angles with respect to its longitudinal length direction, and in the case, space D can less (thickness that is a bit larger tham band, rather than width).
When winding core 10 is inserted in up-coiler and occupy in Fig. 1 and 2 by the position shown in mark 10X, mechanical fastening system is in position shown in Figure 5 and location, make edge 33B and encircle the space of defining between 53 consistent with the end SX of tear-strap, that is, tear-strap is positioned at this space.In structure shown in Figure 5, the end SX of tear-strap S does not engage with anchor fitting 21, thereby anchor fitting rotates freely together with winding core 10,10X, like this, can make the outer circular velocity of described winding core rotation corresponding with the speed of web N.
Be provided with actuator near anchor fitting 21 in coil winder, this actuator comprises a pair of cylinder-piston system 81 that is for example carried by fixed sturcture 83, is schematically shown as Fig. 5 and 6.The bar 82 of cylinder-piston actuater 81 is towards the actuation element 57 of sliding part 45, and separates a little spacing with sliding part 45.When tear-strap S must be fixed to the winding core 10X that has begun to rotate, cylinder-piston actuater 81 started, thereby promoted sliding parts 45 by bar 82.The application force that the bar 82 of cylinder-piston actuater 81 applies is enough to overcome the magnetic maintenance application force that magnet 43 applies, thereby sliding part 45 separates with flange 41 and magnet 43, and occupies position shown in Figure 6.
In this position, the end SX of tear-strap S still is limited in encircling 53 and vertically between the edge 33B of wall 33, because the bar 82 of cylinder-piston actuater 81 applies lasting thrust, thereby at ring with vertically applied enough pressure between the edge of wall.Winding core 10,10X are just around its axis A-A rotation.The first disc-shaped element 51 is coupled with reversing, thereby rotates together with winding core with winding core 10,10X.The edge 33B and the tear-strap S between the first disc-shaped element 51 that are maintained at vertical wall 33 of winding core 10,10X begin to reel in a spiral manner around vertical wall 33, and this vertical wall has formed the base portion 31 of winding core 10,10X.
Owing to having realized being coupled in the solution aspect torsion by bearing 55, so actuation element 57 do not participate in around the rotatablely moving of winding core 10,10X axis A-A, but actuation element 57 still engages the bar 82 of cylinder-piston actuater 81 aspect torsion.As long as must apply enough large maintenance application force on the SX of the end of tear-strap S, and only can not realize described maintenance application force due to the effect of the elastic element 69 of holding device 61, this situation just will continue.
In case tear-strap S has been wound on around winding core 10,10X fully in a spiral manner and web N has begun to reel around described winding core, just no longer need to apply strong maintenance application force on the SX of the end of tear-strap S, thereby cylinder-piston actuater 81 can withdraw from use.Under these situations, only due to the effect of the compression elastic element 69 of holding device 61, sliding part 45 just can keep arrangement form shown in Figure 6, thereby can be used to another coiling cycle until the reel of winding core and moulding separates this winding core.Be used for next coiling before the cycle at winding core, " replacement " anchor fitting 21, should " replacement " operation comprise, the application force that makes sliding part 45 overcome the elastic element 69 of holding device 61 moves along pin 35, until actuation element 57 magnetically engages magnet 43, this magnet is by carrying with sleeve 37 all-in-one-piece flanges 41.
Fig. 7 to 10 shows the variant embodiment for the device of stationary burst band S.Use identical figure notation to represent and the corresponding identical or equivalent elements shown in Fig. 5 and 6.
In this embodiment, the retaining element 91 that is used for stationary burst band S be associated with disc-shaped element 51 (be associated with the ring 53 that the elastic compression material is made fully, valuably, the friction coefficient of this material is high, encircle and the edge 33B of wall 33 cooperatively interacts).Can be more readily understood effect and the structure of retaining element 91 with reference to Fig. 9 and 10, Fig. 9 and the 10 planar I X-IX along Fig. 7 show the cross section of retaining element 91.
In the case, disc-shaped element 51 and winding core 10,10X are aspect torsion and separate in the axial direction, thereby when winding core 10,10X began around its axis A-A rotation, disc-shaped element kept transfixion.
