The method of high-speed winding of narrow long thin-sheet
The present invention relates to a kind of in the wireline reel or the method for high-speed winding of narrow long thin-sheet on the fixing support tube on it, especially a kind of with the narrow long thin-sheet high-speed winding in large diameter roller and in coiling, can not cause the method for any deflection.
In order to prevent metal tape in the roller, for example the adjacent turn of copper, copper alloy, SUS (comprising that those are tin-plated) and metalloid band is owing to damaging, and thin slice is often used as packing element.
Fig. 4 has represented a kind of traditional diced system 50 of metal tape.The diced system 50 of metal tape is high speed rip cutting metal tape under tension force, and as copper, copper alloy, SUS (comprising that those are tin-plated) and metalloid band, with this rip cutting band of horizontal wraparound, the method for the metal tape of promptly reeling is identical with the method for twining metal wool on bobbin.
Usually, system 50 comprises: one has the withdrawal roller 52 of the metal tape 51 of preset width; One under tension force, is used for the cutting machine 54 that metal tape 51 cut-outs or rip cutting from withdrawal roller 52 unwindings are become a plurality of bonding jumpers 53; The take up roll 56 that is used for a plurality of not band brake devices of horizontal wraparound metal tape 53.
Immediately following after the withdrawal roller 52, the one thin slice detector 58 that ruptures/skid off is set, is used to survey various fractures and skids off motion, be i.e. the excessive oscillating motion of narrow long thin-sheet F, before arriving cutting machine 54, send a detectable signal 61 and be used for making immediately metal tape 51 to stop at thin slice F.
When thin slice F is placed on the metal tape 51, send this detectable signal 6 to control panel 60 from detector 58.One receives detectable signal 61, and control panel just sends a danger signal 62 to each withdrawal roller 52 and cutting off machine 54, before arriving cutting off machine 54 at thin slice F the zone that is detected of thin slice F is just stopped rapidly.
This a plurality of bonding jumpers 53 that are cut off machine 54 cut-outs are deflections with respect to their pairing take up rolls 56, and at horizontal wraparound from the position of numeral 1 to 5.
As mentioned above because metal tape 51 is wound up on the withdrawal roller 52 under the condition that is lined with as the thin slice F of packing element, so, when metal tape 51 by unwinding and when cutting off machine 54 transmits, need coiling thin slice F.Fig. 5 is the details drawing of withdrawal roller 52.As shown in the figure, thin slice F is wound onto on the refill 57 with the linear velocity identical with metal tape 51.Refill 57 is fixedly installed on the wireline reel 55, and axle 55 is arranged near the withdrawal roller 52.
In the prior art, realization is wound up into width and the winding speed that thin slice F is depended in operation on the refill 57 with thin slice F, promptly when the width of thin slice F during greater than 250mm, can be without any troublesomely thin slice F directly being wound on the refill 57 from withdrawal roller 52, refill 57 is fixed on the wireline reel 55 of torque motor.When torque motor is worked, on thin slice F, produce enough winding tensions.In this case, the speed of coiling thin slice F can surpass 100m/min.Under good condition, when the width of thin slice F 250 in the 200mm scope time, between refill 57 and withdrawal roller 52, need establish a guide bar.Thin slice F cross motion is restricted, and is being wound up on the refill 57 under this limiting condition.Though torque motor only needs to produce winding tension, when thin slice F winding speed surpassed 100m/min, concerning torque motor, coiling thin slice F was difficult under good order and condition.Width at thin slice F is less than or equal under the situation of 200mm, more needs to use dancer rools to be used to keep the continuous tension force of thin slice F.Though thin slice F cross motion is restricted and be wound up under this limiting condition on the refill 57, for coiling thin slice F under good order and condition, the speed of coiling thin slice F need be less than or equal to 100m/min.
As mentioned above, in the method for traditional winding of narrow long thin-sheet F, for example, the thin slice F that is less than or equal to 200mm when width is when reeling more than or equal to the winding speed of 100m/min, air is among the roller FR of coiling thin slice F, so that form air layer 68 between the adjacent turn of the thin slice F in roller FR.Therefore, in the running of reeling, the skin friction force (or friction coefficient) between the adjacent turn of the thin slice F in roller FR reduces significantly, and this causes the horizontal slip of thin slice F.It is outer and enter manufacturing line with metal tape 51 that this horizontal slip of thin slice F finally causes thin slice F to skid off roller FR.This is the intrinsic problem of orthodox method.In addition, in orthodox method, because the winding tension of thin slice F is not eliminated, refill 57 is broken down through the winding pressure of the thin slice F that is everlasting, and thin slice F can't be involved among the good roller FR, nor can prevent that the thin slice F that skids off from entering manufacturing line with metal tape 51.
Owing to reason above-mentioned, in the method for traditional winding of narrow long thin-sheet F, the winding speed of thin slice F is defined as maximum 100m/min.Because this qualification, in the diced system 50 of conventional metals band 51, the linear velocity of metal tape 51 also is defined as maximum 100m/min.In addition, because thin slice F laterally skids off roller FR easily, so it is difficult involving in thin slice F among the major diameter roller FR of diameter more than or equal to 200mm, this need change a large amount of refills, has increased setup time, thereby has reduced the capacity rating of diced system 50.
In the manufacturing line of using legacy system 50, normal in order to keep manufacturing line, require the operator constantly to look after the roller FR of thin slice F.
In view of the intrinsic problem of above-mentioned prior art, the objective of the invention is to propose a kind of with the method for narrow long thin-sheet high-speed winding to the major diameter roller, and the loss that in coiling, causes without any deflection.
According to first kind of situation of the present invention, can realize above-mentioned purpose of the present invention by the following method:
A kind of in the wireline reel or the method for a kind of narrow long thin-sheet material of high-speed winding on the fixing support tube on it, its innovative approach comprises:
Laterally compress narrow long thin-sheet to reduce the width of narrow long thin-sheet by a pair of guiding device that is spaced laterally apart each other, the guiding device partition distance is less than the width of described narrow long thin-sheet, before its position next-door neighbour's narrow long thin-sheet is rolled on the wireline reel; And
Under this impaction state, narrow long thin-sheet is wound up on the wireline reel.
In the method for the invention because narrow long thin-sheet is by the horizontal pressurized of guiding device, when this winding of webs to wireline reel or it on the fixing support tube time, thin slice is pressurized, and so wrinkle.Next circle of thin slice in the wrinkle of thin slice parts and the same roller contacts then, prevent to form continuous air layer between two-layer, prevent that skin friction force (being friction coefficient) reduces between the adjacent turn of thin slice in the roller, and prevent that therefore thin slice laterally skids off outside the roller when coiling.
According to second kind of situation of the present invention, can realize above-mentioned purpose of the present invention by the following method:
First kind of situation of the present invention as described above, in the high-speed winding of narrow long thin-sheet method:
Described that can transversely moving relative to each other to guiding device at described narrow long thin-sheet, thereby can according to the width adjustment of narrow long thin-sheet this to the distance between the guiding device, so that in the time of on the support tube that is rolled onto thin slice on the wireline reel or fixes on it, thin slice presents favourable wrinkle or curved shape.
According to the third situation of the present invention, can realize above-mentioned purpose of the present invention by the following method:
First kind or second kind of situation of the present invention as described above, in the method for high-speed winding of narrow long thin-sheet:
Narrow long thin-sheet is upwards to lift on its relative limit so that the middle section of its cross-sectional plane is presented under the situation of spill to reel.
This prevents between the adjacent turn of thin slice to form continuous air layer laterally slide on roller so that prevent thin slice, therefore in same roller the following circle of thin slice or outer ring that inner ring can hold thin slice securely or on circle.Thereby even thin slice is rolled onto on the major diameter roller, when reeling, the roller of in fact this structure does not have the deflection situation yet on width.

Below, with reference to accompanying drawing, describe the relevant method of twining narrow long thin-sheet at a high speed of the present invention in conjunction with the preferred embodiments in detail.
Fig. 1 realizes that high speed of the present invention twines the enlarged perspective of major part of the withdrawal roller of narrow long thin-sheet method.
The device of withdrawal roller shown in the figure 10 comprises: a unwinding roll shaft 12; A plurality of guide bar 14,16; One is used to support the pivot shaft 18 of a pair of guiding piece 24,24 of exerting pressure; With a wireline reel 20 that paper web or refill 22 be set on it.Exerting pressure in the guiding piece 24,24, at least one is movably with respect to another, can regulate the distance between the pressurized guiding piece 24,24.
Show that as Fig. 2 is detailed each guiding piece 24,24 of exerting pressure comprises: one is slidably mounted on the sleeve-like part 24a on the pivot shaft 18; With a discoid cam 24b who links together by welding integral ground and sleeve-like part 24a.
Shown in Fig. 2 B, cam 24b is an accentric with respect to the simple shape part 24a of cover, forms a big radially projection; Shown in Fig. 2 A and 2B, projection compresses with the edge of long narrow thin slice F to following stretching, extension and its inside face and contacts, and therefore, thin slice F is compacted and guiding by cam 24b.If desired, this can be regulated by loose bolts 25 gently the distance of exerting pressure between the guiding piece 24,24.After the adjusting, bolt 25 is by fastening so that the required distance between the guiding piece 24,24 of exerting pressure is set once more.Because said structure, it is possible exerting pressure and according to narrow long thin-sheet F one optimum distance being set between the guiding piece 24,24, and the width of described narrow long thin-sheet F can be different.Preferably, exert pressure distance between the guiding piece 24,24 in the 0.5-0.8W scope, wherein W is the width of narrow long thin-sheet F.
As mentioned above, be winding to wireline reel 20 or the position before on the fixing refill 22 on it at next-door neighbour narrow long thin-sheet F, thin slice F is by those guiding piece 24,24 horizontal pressurizeds of exerting pressure to separating each other, and the distance that the described guiding piece of exerting pressure separates each other is littler than the width of thin slice F.So this pressurized thin slice F is twisted in wireline reel 20 or on it on the fixing refill 22.Therefore, this thin slice of being reeled is wrinkle, and its wrinkle part contacts with next circle of thin slice F in same roller FR.Because this contact prevents to produce horizontal air layer continuously between the adjacent turn of thin slice F, therefore prevents that thin slice F from laterally sliding.
With reference to Fig. 1, metal tape 11 and narrow long thin-sheet F are wound up among the roller R together, and roller R is rotated and is fixed on the unwinding axle 12.In this case, when sheetmetal 11 unwindings and when being sent to tape-cutting machine 54 (shown in Figure 4), as the same length of the metal tape 11 of the narrow long thin-sheet F of packing element also unwinding and unwinding.Therefore, the thin slice F of unwinding need be wound up on the wireline reel 20.In this operating winding began, wireline reel 20 was high speed revolutions.Yet when thin slice F was winding on the wireline reel 20, the winding speed of axle 20 progressively slowed down.In order to make the thin slice that transmits to roller FR keep constant tension force, as shown in Figure 1, a dancer rools 16 can be set, vertical shifting in the vertical slotted hole 26 that it can be provided with on take-off device 10.
In addition, shown in Fig. 2 A, when in that each cam 24b is inboard when forming sweep 24c, the cross-sectional plane of narrow long thin-sheet F is curved, be convenient to that narrow long thin-sheet F is wound up into wireline reel 20 or the refill 22 fixed it on.As mentioned above, when narrow long thin-sheet F upwards lifts on its corresponding limit and central cross section is when being reeled under the condition of concave surface, can prevent to produce air layer extending transversely between the adjacent turn of thin slice F among the roller FR, prevent that thin slice F from laterally sliding in the roller FR of thin slice F.In addition, in the roller FR of thin slice F, because in same roller FR, following circle or inner lane that roller FR goes up thin slice F hold circle or outer ring securely, even so when the thin slice quilt was last around a large diameter roller FR, in fact thin slice F can not be offset on the width of the roller FR of thin slice F yet.Therefore, even when the linear velocity of cutter sweep 50 reaches 200m/min, do not worry that also thin slice F skids off outside the roller FR, these can make the external diameter of roller FR reach 350mm, and the maximum outside diameter of the roller FR of traditional thin slice F only is 150mm.This large diameter roller FR that the present invention relates to has reduced to be used to change the set-up time of refill 22.In addition, in method of the present invention, the operator frees from the heavy burden of the roller FR of continuous inspection thin slice F.Because these facts, can significantly improve capacity rating according to the diced system of the inventive method.
As shown in drawings, in a preferred embodiment of the invention, be that 0.002Kg/mm (per unit width) prevents that refill 22 fragmentations from being possible by the winding tension that thin slice F is set, and can prevent that also thin slice F from fractureing.
In the method for high-speed winding of narrow long thin-sheet F of the present invention, position before next-door neighbour's thin slice is winding to wireline reel, thin slice is by the horizontal pressurized of a pair of guiding device that separates each other (induction element 24 of promptly exerting pressure), the distance that guiding device separates is less than the width of thin slice, and thin slice is reeled under this pressurized condition.Therefore, when winding of webs to wireline reel or on it on the fixing refill time, thin slice is wrinkle, make a part of wrinkle thin slice in the roller contact with the inner ring of thin slice in the same roller, prevent to produce horizontal air layer between the adjacent turn of thin slice in the same roller continuously, thereby prevented that skin friction force or friction coefficient between the adjacent turn of thin slice among the roller FR from reducing.Therefore, laterally to slide in roller be possible to each circle that prevents thin slice.This is a distinctive advantage in the inventive method.
Because above-mentioned advantage, cause the number of times of line fault significantly to reduce by the trouble of winding of webs device generation, reduced the monitoring burden of operator in the operating winding of the roller of thin slice, therefore, it is possible that the system that realizes the inventive method reaches 50% work efficiency, and adopts the work efficiency of conventional apparatus to be no more than 30%.
