From then on the position begins, the operator can hold handle 34, at first manually promote handle 34 with compression spring 156 to radially outer direction, and inserted sheet 150 is broken away from cover location division 142, manually the clickwise handle arrives the end of recesses 140 so that inserted sheet 150 moves along the first 141 of recess 140 up to inserted sheet 150 then.In this rotary course, because the inserted sheet 150 of handle engages slidably with the groove 64 of wheel hub 22, so (outside) first wheel 22 and handle rotate (referring to Fig. 8) simultaneously.When can not be more further during clickwise, promptly inserted sheet 150 arrives the end of recesses 140 and when contacting with the sidewall of recess, first and second wheel hubs are oriented and are in the second above-mentioned position of rotation.Wheel hub to be turned back to first position of rotation, the operator only need hold handle 34 and manual left-hand revolution handle 34, till the opposing sidewalls (near the sidewall of lid location division 142) of inserted sheet 150 contact recesses 140, so spring 156 forces handle radially to move inward, make inserted sheet 150 engage with lid location division 142 once more.Should be understood that, can easily revise reel assembly to put upside down the direction of rotating handles 34, make that reel assembly is transformed into second (contraction) position of rotation from first (stretching, extension) position of rotation needs the left-hand revolution handle, needs the clickwise handle and reel assembly is transformed into first (stretching, extension) position of rotation from second (contraction) position of rotation.
In general, the suitable material of formation handle 34 and boss 154 comprises (for example) metal, for example aluminium or corrosion-resistant steel; Plastics, for example blend or the compound of PVC, the styrene that contains ABS, thermoplastic plastic (for example polyethylene, nylon or polyester), thermosetting plastic (for example some polyester, rubber or epoxy resin), these type of plastics; Or other suitable reel assembly material.
Fig. 8 shows the transparent view of the reel assembly 20 that final assembling finishes.Flange 28 and end plate 30 are connected on second (inside) wheel hub 26 (Fig. 1 and Fig. 4 A), to form the cylinder of assembly 20, first (outside) wheel hub 22 (should be understood that around this cylinder rotation, in other embodiments, assembly 20 can be constructed so that the action need of assembly 20 is with respect to first wheel 22 rotations second wheel hub 26).Like this, first wheel 22 coaxial being arranged on second wheel hub 26, and remain on rotationally between flange 28 and the end plate 30.
Fig. 9 A shows the cutaway view that assembles reel assembly 20 (for example, wheel hub 22,26 is in first position of rotation) that is in extended configuration.Second wheel hub, 26 coaxial being arranged in the first wheel 22, and movable member 24 is pivotably connected on the first wheel 22 along rear end 72.The radius that the area supported 76 of movable member 24 is positioned at slope 118 is near partial sum first side 120 of R1, and the outside face 54 that makes coiling surface 74 deviate from first wheel 22 raises, with the stretching, extension foreign volume shaft diameter D of limitation unit 20
Max(as the reference point, assembly 20 defines the contraction foreign volume shaft diameter D when being in contraction state

MinLess than D
MaxExtended configuration and contraction state also all have corresponding effective diameter, and the effective diameter of extended configuration is not more than D
Max, but greater than the effective diameter of contraction state, the effective diameter of contraction state is not more than D

Shown in Fig. 9 A, wheel hub 22,26 optionally is locked in first position of rotation, make area supported 76 remain near the part that radius is R1, but 118 tendencies that 118 first side 120 is radially inwardly slided to top, slope 122 from the slope are arranged along the slope.Therefore, when at first position of rotation, movable member 24 is arranged to the foreign volume shaft diameter D that coiling surface 74 is limited
Max(being in extended configuration) is positioned at the outside of the outside face 54 of first wheel 22.
Like this, the coiling surface 74 of a plurality of movable member 24 capable of being combined is wound on the outside face 54 of first wheel 22 to prevent cylinder material.By the movable member of suitable layout sufficient amount, and reel assembly 20 is in extended configuration, and the cylinder material of coiling can extend to another coiling surface from a coiling surface 74, and can not contact the outside face 54 of first wheel 22.

MinIn about scope of 1% to 5%.That is to say that (that is, wheel hub rotates to second position of rotation to be transformed into contraction state at assembly 20, for example, as shown in figure 10) afterwards, can remove from assembly 20 being wound on the stiff basically cylinder material that stretches on the assembly 20, even work as the reel diameter D of extended configuration

On the contrary, for elastomeric easy-to-stretch coiling block material, the reel diameter D of extended configuration
MaxMore significantly greater than the reel diameter D of contraction state
Min(for example big 5 to 100%).In the time of on being wound on reel assembly, the elastic roll material stretches usually, forms radially inner quiescent load.Quiescent load is born by assembly during reeling, but should discharge substantially after coiling is finished, to allow to remove the reel of winding.This finishes by making reel assembly be transformed into contraction state from extended configuration, wherein contraction state is compared enough little (diameter under the extended configuration or effective diameter are fully greater than diameter under the contraction state or effective diameter) with extended configuration, so that quiescent load is released basically.
Fig. 9 B shows the cutaway view of the reel assembly that is in extended configuration 20 shown in Fig. 9 A, but also shows the cylinder material 158 of tightening coiling around reel assembly.A plurality of movable members 24 prevent that cylinder material 158 from contacting with the outside face 54 of first wheel 22.In addition, each coiling surface 74 comprises master file around surface 159 and time coiling surface 160, and wherein master file 159 extends maximum radial distance and (thereby defines the foreign volume shaft diameter D of extended configuration around the surface from the center of assembly 20
Max).In this regard, " coiling surface " is meant when cylinder material is reeled (or winding) around spool, the surface that cylinder material contacted (usually when spool is in its extended configuration).It should be noted, can make amendment,, or on each movable member, form two or more coiling surfaces that separate so that on each movable member, only form a coiling surface (for example, master file is around surface 159) to the shape of movable member 24.In addition, if the shape of movable member can not stop cylinder material to contact with the outside face 54 of first wheel 22, then also can make a plurality of parts of this type of outside face 54 become coiling surface.Yet, for the structure of Fig. 9 B, when cylinder material 158 is wound on the assembly 20, the coiling path 161 of coiling surface 159,160 supporting drum materials 158 and qualification cylinder material 158.Like this, cylinder material 158 contacts with distinct coiling surface 159,160 on each movable member 24.Therefore, depend on the shape or the design of movable member, the surface as coiling surface 74 can comprise two or more discrete, non-adjacent coiling surfaces at first.
Preferably, each movable member 24 is shaped on wheel hub and orientation, make that when reel assembly is in extended configuration the part of the maximum quiescent load of the supporting drum material of movable member is extended along the direction that is roughly parallel to this load direction, to obtain maximum stability and intensity.Referring to Fig. 9 B and 9C, when assembly is in extended configuration, tighten the roughly radially inside centre of gration of quiescent load direction of the cylinder material 158 of coiling towards wheel hub 22,26, and the part of the maximum quiescent load of the supporting drum material of each movable member 24 (that is, in the part of master file around 76 of surface 159 and area supporteds) also roughly extends radially inwardly.
Coiling path 161 need not to be circle; In fact, it is not accurate circle usually.For example, as shown in the figure, coiling path 161 is non-circular, and crosses the inferior coiling surface 160 that movable member 24 arrives circumferentially adjacent movable member 24 around surface 159 from the master file of a movable member 24.Can use the girth in coiling path 161 to calculate effectively (extended configuration) foreign volume shaft diameter, promptly use the coiling path circumference divided by π.Therefore, diameter is that the circle of effective diameter has the girth with the equal in length in a circle coiling path 161.
Though show four movable members 24, but should be understood that, under the gained assembly is constructed to make the situation of effective foreign volume shaft diameter than the effective foreign volume shaft diameter under the contraction state big 1 to 100% or more (or 20 to 60%) under the extended configuration, even can only provide a movable member 24.
Fig. 9 C shows the transparent view of the free body diagram of the movable member 24 that other parts with reel assembly 20 separate.Movable member 24 is fixed on the first wheel 22 by the 78a of ear, 78b and hinge inserted sheet 80.Though member 24 preferably is made of the metal with enough rigidity or other material, basically can obviously not be out of shape with the quiescent load that supports the cylinder material of having reeled, but the structure of member 24 (for example, in a plane is arc or curved shape, and is the stamped sheet metal or the thin plate of smooth or straight shape in orthogonal plane) also preferably allow front end 70 responses of movable member 24 to carry out a spot of bending or rotation by cylinder material 158 (Fig. 9 B) applied force.Like this, front end 70 response take-up force, and preferred and automatically move with respect to the axis of reel assembly 20, to realize automatic tracking cylinder material 158, hereinafter will be described in more detail this.Movable member 24 comprise central longitudinal axis C and with the axis T of front end 70 lateral alignment.Reel assembly has rotation axis A (that is the axis shown in Fig. 9 C in the clearance envelope, but should be understood that axis A overlaps with D1 shown in Fig. 9 B and the intersection point of D2).When the part as reel assembly 20 was assembled, movable member 24 was fixed on the first wheel 22 by the 78a of ear, 78b, made front end 70 arrange with respect to rear end 72 cantilevereds.Can say on the meaning of deflection that at movable member first side 162 of coiling surface 74 and second side surface opposite 164 can be with respect to fixing rear end 72 translations and rotations.Specifically, side 162,164 can be around central longitudinal axis C rotation and with respect to first wheel 22 translations, independently, automatically and correctly regulate the orientation of the axis T of front end 70 with respect to reel assembly axis A to respond differential tension on the whole cylinder material width, thereby when winding web materials, cylinder material keeps being centrally located on the reel assembly, rather than resembles the glass that draws back more and more away from reel assembly.
The take-up force that is delivered on the movable member 24 from cylinder material 158 (Fig. 9 B) may be unbalance, and may cause unbalanced accumulation potentially in the cylinder material 158 of reeling.Yet, this overbalance in the cylinder material 158 that movable member 24 responses are reeled, and can form the automatic tracking feature, each side 162,164 is independent of that external hub 22 moves freely and the orientation of automatically regulating front end 70 thus, makes axis T regulate (for example alignment) accordingly with respect to reel assembly axis A.
During winding web materials 158, the variation of the variation of cylinder material 158 thickness and cylinder material 158 external force all can cause overbalance occurring along the side direction tracking of 74 pairs of cylinder materials 158 of coiling surface.Do not wish to be bound by theory, it is believed that the cantilevered front end 70 of movable member 24 is rotated and translation during reeling, to adapt to unbalanced power and to proofread and correct the side direction of cylinder material 158 is followed the tracks of may change with respect to coiling surface 74.
For example, referring to Fig. 9 A-9C, if the take-up force overbalance of cylinder material 158 make that the take-up force on the side 162 is big, and the take-up force on the side 164 is little, then side 162 downward deflections (that is, this side of area supported 76 along the slope 118 slightly move down).Thereby side 164 becomes and raises with respect to 162, and the axis A that axis T becomes with reel assembly does not line up.When winding web materials, thisly be considered to unsettled obliquity usually and can adapt to out-of-balance force in the cylinder material, and keep cylinder material placed in the middle on reel assembly.Thereafter, (take-up force on the side 164 is big for reverse overbalance if if take-up force becomes in become on the whole cylinder material balance or they, and the take-up force on the side 162 is little), front end 70 can respond the power of these variations and carry out translation and rotation, to redirect axis T with respect to reel assembly axis A.Therefore, the design of movable member 24 allows horizontal dimension power of its response out-of-balance force or variation or tension force and carries out slight deflection, play the effect of a kind of " independent suspension ", with the power of the axis of pitch response out-of-balance force that allows coiling surface or variation and redirect, thereby keep cylinder material placed in the middle on reel assembly during reeling with respect to spool axis A.
It should be noted that the structure of movable member that the automatic tracking feature is provided comprises the reel assembly that may only have a wheel hub applicable to multiple reel assembly, and the reel assembly of other traditional design.
Figure 10 shows the cutaway view of the wheel hub 22,26 that is in second position of rotation, and this position makes reel assembly 20 be in contraction or retracted mode.Under contraction state, movable member 24 pivots, and make coiling surface 74 (with respect to the locus under the extended configuration) withdraw, and assembly 20 is by approximating the foreign volume shaft diameter D of D1 (diameter of first wheel 22) greatly
MinCharacterize.In the conversion from the extended configuration to the contraction state,, the first wheel 22 and second wheel hub 26 are relative to each other rotated by moving handle 34 (Fig. 8).That is to say that wheel hub 22,26 rotates to second position of rotation from first position of rotation (Fig. 9 A, 9B), wherein area supported 76 is near first side 120 on slope 118 when first position of rotation, and area supported 76 is admitted by depressed part 116 when second position of rotation.
The moving process from first position of rotation to second position of rotation, first wheel 22 is rotated with respect to the direction of second wheel hub 26 according to arrow 170, make the area supported 76 of movable member 24 118 move along the slope, 118 first side 120 is radially inwardly through top, slope 122 from the slope, and admitted by depressed part 116, coiling surface 74 is inwardly bounced back, and assembly 20 is in contraction state.
Preferably the area supported under the extended configuration 76 is arranged in relative maximum potential position near first side 120 on slope 118.Therefore, movable member 24 tends to move to and the position relevant than the low-potential energy position naturally, for example the position that is reached when area supported 76 moves to position near top, slope 122.Strengthen quasi-balanced state under this extended configuration by inside compressive force, this inside compressive force is applied by the winding web materials that is wound on the coiling surface 74.
Thereafter, when the operator wanted to remove the cylinder material of having reeled, he or she can pass through handle 34 manual rotary hubs 22,26, makes assembly 20 be transformed into the contraction state of Figure 10.As mentioned above, when cylinder material was wound on the coiling surface 74, assembly 20 tended to the contraction state conversion to Figure 10.At this contraction state, coiling surface 74 is inside retraction preferably, makes foreign volume shaft diameter D
MinOr effectively the foreign volume shaft diameter is decreased to and is substantially equal to D1 (diameter of external hub 22), thereby the cylinder material of having reeled can be removed from the assembly 20 that shrinks easily.
In alternative reel assembly, compare with foregoing, the effect of first and second wheel hubs can be put upside down at least in part.For example, if externally provide in the wheel hub size suitable slit, extensible these slits that passes of movable member then are so that the back is along being pivotably connected on the inner hub.In addition, externally provide depressed part and slope for each movable member in the wheel hub, and the area supported of movable member (near its forward position) but engagement concave portions, thereby movable member slides along the slope when wheel hub relative to each other rotates, the coiling surface that forces each movable member radially outward or inwardly, with extended configuration or the contraction state that forms this alternative reel assembly respectively.Figure 11 A shows the alternative reel assembly that is in extended configuration, and Figure 11 B shows the alternative reel assembly that is in contraction state.
Figure 12 shows the transparent view of the system that is used for the processing winding drum material.This system 200 comprises unwinding axle 202, and this unwinding axle keeps the source of supply 204 of cylinder material rotatably; Separation station 206; And reel assembly 20a and 20b, described reel assembly rotatably remains on the downstream of the source of supply 204 of cylinder material.In alternative embodiment, can only adopt one (for example assembly 20a) among assembly 20a, the 20b, maybe can adopt to surpass two assemblies.
Unwinding axle 202 is admitted the reel of the winding of stacked cylinder material source of supply 204, separation station 206 is separated into output products and one or more residue carrier (or waste material) cylinder material of expectation with the sandwich of cylinder material source of supply 204, and reel assembly 20 coilings carrier/waste material cylinder material is to carry out follow-up processing or recycling.As mentioned below, in some cases, the sandwich of cylinder material source of supply 204 has two carriers/waste material cylinder material, and adopts two reel assembly 20a and two the waste material cylinder materials of 20b to reel and to come out from separation station 206.In other embodiments, the waste material cylinder material of reeling one of only is provided among reel assembly 20a and the 20b, but should be understood that, in the time will reeling plural waste material cylinder material, can advantageously adopt plural reel assembly.
Unwinding axle 202 is usually located at the upstream of separation station 206, and is positioned at the upstream of and/or a plurality of reel assembly 20.In one embodiment, unwinding axle 202 is driven by the electrical motor (not shown), by control panel 207 these electrical motors of control.Alternatively, unwinding axle 202 and one and/or a plurality of reel assembly 20 all are subjected to the driving by the electrical motor of control panel 207 controls.Unwinding axle 202 all can form rolling-in tension force with respect to any rotation difference of and/or a plurality of reel assembly 20 in the waste material cylinder material on being wound in and/or a plurality of reel assembly 20.
Because the waste material cylinder material is usually processed subsequently to be fallen or recycles, so wish waste material reel material webs around for to tighten the reel of compression so that its minimized in size.The rolling-in tension force that is delivered on one and/or a plurality of reel assembly 20 may be very big, and be under the situation of polymer thin-film material at the waste material cylinder material, rolling-in tension force can be at 1 pound of every line inch (pli) (0.18 kilogram every line centimetre) (allowing the waste material cylinder material " to float " with minimum tension in the application on assembly 20) to 50pli or bigger scope.Therefore, towards the radially inner compressive force of reel spool at several ft lbfs to the scope of hundreds of ft lbf.For example, when when reeling the waste material cylinder material of some based thin film, but the compressive force of 400 pounds of 20 Zhi Chengyue of the reel assembly with four corrosion-resistant steel movable members 24 that illustrate, and on this compression force distribution to four movable member 24.
The source of supply 204 of cylinder material comprises back sheet 210, overplate 212 and is the output products of a plurality of film band 214 forms.Yet in some applications, overplate 212 is optional.During use, the source of supply 204 of unwinding axle 202 unwinding cylinder materials, and separation station 206 makes a plurality of film bands 214 separate with overplate 212 with back sheet 210. Reel assembly 20a and 20b are wound as centreless waste material reel with waste material/unnecessary back sheet 210 and overplate 212.
In the illustrative processes of winding web materials, control panel 207 receives the input data and drives unwinding axle 202, guides to separation station 206 with the source of supply 204 with cylinder material.Separation station 206 makes a plurality of available film bands 214 separate with overplate 212 with back sheet 210.With respect to Figure 12, reel assembly 20a is around the coiling surface 74 coiling waste material back sheets 210 that stretch, and reel assembly 20b is around the corresponding coiling surface 74 coiling waste material overplates 212 that stretch.As mentioned above, waste material layer 210,212 can sizable rolling-in tension level be wound on reel assembly 20a, the 20b.This reel of tightening the waste material layer 210,212 of coiling may make plastics and/or board fiber board core cave in potentially.
By contrast, each reel assembly 20a, 20b all are configured to stand high rolling-in tension force, though when cylinder material also be like this when spaced apart only by the coiling surface of movable member supporting (reel assembly is in extended configuration) and with the outside face of external hub separately.After the film band 214 with desired amt separates from cylinder material source of supply 204, can manually make reel assembly be transformed into contraction state, at this moment foreign volume shaft diameter D

Figure 13 A shows the cutaway view of another reel assembly 300 that is in the first stretching, extension position of rotation.This reel assembly 300 comprises first wheel 302; Second wheel hub 304, it is with respect to first wheel 302 coaxial settings; And first movable member 306, it is arranged between the first wheel 302 and second wheel hub 304.
A plurality of movable members 306 can be arranged in a plurality of cooresponding slits 312, make movable member 306 be associated with a plurality of transition regions 316 in being formed on second wheel hub 304.Alternative embodiment can use one, two, three or four or more a plurality of movable member 306 and cooresponding slit 312.When more than one slit 312 was provided, slit was preferably arranged basically equally spacedly along the periphery of wheel hub 302.
For example, diameter DD crosses the center of first wheel 302 and extends to the opposing outer face 308 of first wheel 302.Coiling surface 330 extends beyond the outside face 308 of diameter DD and first wheel 302, and the distance that exceeds is H.Under extended configuration, first side 322 on the area supported 332 contact slopes 320 of movable member 306 makes coiling surface 330 outwards protrude distance H from slit 312, arrives the position that (that is, surpasses outside face 308) outside the outside face 308.Like this, the movable member 306 of stretching, extension defines the foreign volume shaft diameter of assembly 300, and this foreign volume shaft diameter is than the big distance H of diameter DD of first wheel 302.If identical movable member 306 is arranged in the opposite side of reel assembly 300, then these two movable members limit the foreign volume shaft diameter of extended configurations, the big 2H of this foreign volume shaft diameter diameter group DD.According to the quantity of the movable member 306 that distributes around reel assembly 300, the effective diameter diameter group DD of reel assembly 300 that is in extended configuration is big, but difference is no more than 2H.For example, the movable member 306 of sufficient amount can be provided and make its circumferential distribution that centers on reel assembly 300, so that the coiling surface 330 of movable member 306 makes up to prevent that cylinder material from contacting with the outside face 308 of first wheel 302.
Figure 13 B shows the cutaway view of the reel assembly 300 that is in second position of rotation (contraction state).External hub 302 is rotated by the direction of arrow 340 with respect to inner hub.The area supported 332 of movable member 306 320 moves along the slope, is displaced downwardly to the lowest part 326 of depressed part 318 from first side 322.Preferably, be converted to from extended configuration the process of contraction state, movable member 306 is about the segment distance of H to depressed part 318 withdrawal length, makes coiling surface 330 flush with respect to the outside face 308 of external hub 302, or even retraction.
In the contraction state shown in Figure 13 B, area supported 332 makes movable member 306 almost flush with outside face 308 near the lowest part 326 of depressed part 318.Like this, be in contraction state assembly 300 the foreign volume shaft diameter and effectively the foreign volume shaft diameter approximate the outer dia DD of external hub 302 greatly.Thereby, assembly 300 at the foreign volume shaft diameter under the extended configuration as shown in FIG. 13A greater than the foreign volume shaft diameter under the contraction state shown in Figure 13 B.
Various reel assembly as herein described provides the coreless roll Shaft assembly, it comprises first wheel and with respect to second wheel hub of the coaxial setting of first wheel, wherein can make the relative to each other rotation between first position of rotation and second position of rotation of first and second wheel hubs by M/C.This reel assembly also comprises one or more movable members, described movable member limits foreign volume shaft diameter (comprising effective foreign volume shaft diameter), and change between the contraction state at the extended configuration at the first position of rotation place and the second position of rotation place, the foreign volume shaft diameter under extended configuration is greater than the foreign volume shaft diameter under contraction state.
The direct high pressure of waste material reel that reel assembly can be configured to can stand cylinder material is wound up on the reel assembly coiling surface.In aforesaid way, coiling surface can be shrunk to contraction state at second position of rotation, so that can easily remove the reel that is formed by cylinder material from the mode that the coreless roll Shaft assembly slides by making reel.
In addition, reel assembly can comprise movable member, and movable member is designed to deflection or otherwise moves, so that can the balanced cylinder material of following the tracks of on the coiling surface that is wound on movable member.Thereby, be wound on the cylinder material rolling-in equably on the coiling surface, can deflection or depart from.
As required, the coiling surface of movable member can be contractile, and need not mobile the coiling surface easy and spring-loaded that cylinder material tangles.
