The specific embodiment
To the embodiment with surperficial reel system be described below.Yet, should be appreciated that principle of the present invention can combine with the center reel system.
Accompanying drawing has shown the primary element according to apparatus of the present invention, and has shown its mode of operation.In the embodiment that Figure 1A, 1B, 1C describe, rewinding machine comprises by three take up rolls promptly: the coiling carriage that first take up roll 1, second take up roll 2 and the 3rd take up roll 3 form.Three rollers 1,2,3 around parallel to the axis and (reeling cycle period) with roughly the same circumferential velocity rotation, and they can change at the end of reeling according to known mode itself, and discharge completed reel and/or insert new fuse by the roll gap 5 that is limited between take up roll 1 and 2, follow-up reel begins coiling around this new fuse.
Take up roll 3 is supported on a pair of swing arm 7 that is hinged on the oscillating axle 7A.This hunting motion increases the reel R that is formed in the coiling carriage 1,2,3 and through chute 9 completed reel is unloaded.
The band of being reeled and forming reel R is indicated by N.It is transversely in the feeding path movement of punch unit (not shown), and this punch unit is bored a hole to material N perpendicular to the perforation line of the direction of feed fN of material N along cardinal principle in known manner.In the downstream of punch unit, band N is around deflector roll 11 running, described deflector roll 11 around with the axis rotation of the parallel axes of take up roll 1,2 and 3.The band feeding path part of advancing subsequently, this part is tangential to the roller 1 and 11 that is limited by flexible feeding element 13, and described flexible feeding element 13 is made up of a plurality of flat parallel belts around roller 1 and 11 runnings.As will illustrating subsequently, feed component at first be used for tubular winding fuse A inserted and make its march forward to, reel R reels around this fuse.Because the belt that forms feed component 13 is around roller 1 and 11 runnings, they move forward with the speed identical with band N, and therefore do not have relative motion between the latter and the belt.
Below the part of the feed component parallel, there is the rolling surface 15 of the bending that limits by crooked metal sheet or rod, a plurality of crooked metal sheet parallel to each other or rod or comb shaped structure with band N.Between rolling surface 15 and feed component 13, define insertion and feeding passage, the outlet that it has the import on the left of accompanying drawing and corresponds essentially to the roll gap 5 between take up roll 1 and 2 by the winding core of 17 indications.Therefore the terminal part of passage is limited between the outside face of rolling surface 15 and take up roll 1, and feed component 13 is around this take up roll 1 running, and rolling surface is that arch makes that its surface with roller 1 is roughly coaxial.Surface 15 terminal part deeply is arranged in the annular groove in the take up roll 2, towards roll gap 5 rollings, and arrives coiling carriage 1,2,3 from here with pass through of fuse that easily allows to roll on surface 15.
Import near passage 17 is provided with the fuse licker-in roller of being made up of rotating element 19, and described rotating element 19 is inserted into winding core A in the passage 17 in due course.This fuse is positioned at the front of licker-in roller 19 by chain conveyor 21.The operation that fuse inserts mechanism is well known to those skilled in the art, and for example can understand this mechanism by one or the many pieces of documents of institute's reference in this specification sheets introductory section, and no longer be described in greater detail.
The height of passage 17 equals or is slightly smaller than the external diameter of winding core A, and therefore, when winding core was pushed in the described passage by licker-in roller 19, under the impetus of the motion of feed component 13, winding core quickened with being tilted and rolls on the surface 15 promoting.Band N keeps being clamped in the belt that forms feed component 13 and is inserted between the fuse in the passage.
Be provided with suction element on the shunt of the bottom of licker-in roller element 13, it is indicated by 23 generally and will be below to its detailed description.Suction element has suction areas, and its direction of feed transverse to fuse A and band N is extended.Suction element applies suction to band N at translate phase, promptly, when reel R almost finished, band N must be blocked with generation and be wound on the final free edge on the reel R that finishes and be wound on initial free edge on the new fuse A that is inserted in the passage 17 to begin the coiling of new reel.Swabbing action has produced the application force perpendicular to the lower surface of suction element 23.Be applied to tensioning and the fracture of corresponding friction force on the band by described surface even as big as causing band.
The operation of described device so far is as follows.Figure 1A has shown strip breaks or has blocked next-door neighbour's the moment before.Soon unload around the reel R that reels by the winding core of A1 indication, and new fuse A2 just is inserted in the passage 17 by licker-in roller 19 from the coiling carriage.Advantageously, the structure of passage 17 is so, promptly makes fuse A2 contacting with roller 11 with the belt that forms element 13 before fixedly abutment surface contacts of forming with bottom by suction element 23.Like this, described fuse is quickened rapidly obliquely till itself and the contact point of band reach the Feeding speed identical with band.
Rolling surface 15 has comb shaped structure or at least one serial recess, and it allows licker-in roller 19 to finish axial rotation and prepares to insert next fuse.
P has indicated the position of the cross-perforating line that is produced by the borer (not shown) on band N, band will be torn along this perforation line.Perforation P is positioned at any position, downstream of suction areas, and described suction areas is to be limited by pump orifice, groove and hole along the lower surface of suction element 23 formed suction box.This swabbing action is controlled and regularly is arranged in by the shown position of Figure 1A with convenient perforation line P or operates when being positioned at the downstream part slightly of direction of feed of band N.Like this, when swabbing action was activated, band is braking promptly in suction socket or opening region.When reel R is rotated further, to tear in the point of contact of reel R and the band tensioning between the suction areas and along perforation line P, described perforation line has constituted the most fragile part of band.Take up roll 1 has in the high coefficient of friction surface that forms between the belt 13A of element 13, makes tearing of band occur on the perforation line in the most approaching zone that applies swabbing action.In practice, prevented that with the great friction coefficient on the surface of the contacted roller 1 of band N tension force downstream, propagate towards the reel R1 that just finishes.
Fuse A2 with tear band N with the suction areas upstream and contact and begun and rotate.This fuse remains on band N the loss that has also therefore prevented on the belt that forms feed component 13 owing to the initial free edge Li of the band N that tears formation.In addition, fuse has limited the stretching of band, and described band is owing to the braking that swabbing action applied is slowed down.In fact, the band of the regional upstream that contacts with fuse A2 can not slow down, and therefore is created in the advantage that does not have fold in the reel inner ring.The final free edge Lf of the reel R coiling on reel that is through with in a manner known way, by the circumferential velocity that changes roller 2 and/or roller 3 with described reel discharging.Promote tearing or blocking of band by the swabbing action that is applied on the band, before starting described swabbing action, it also is possible that take up roll 3 is quickened.As long as start described swabbing action, this acceleration (even slight a bit) makes the pre-tensioning of band and guarantees to tear.
In the example shown, on the surface of fuse A2, applied an adhesive that is parallel to wire mandrel.In Figure 1A shown device, described slivering adhesive is positioned at any position, upstream of the clamping point of band N, and therefore after the of short duration rolling of fuse, this band adheres on the fuse.
Because roller 1 and 11 is rotated further, after strip breaks, feed component 13 continues to roll and along passage 17 feeding fuse A2.Contact point between fuse and the feed component 13 is crossed the initial free edge Li of suction areas (Figure 1B) and band N owing to the slivering adhesive that applies thereon adheres on the fuse, thereby begins the coiling of new reel.The reel R that is finished still on the coiling carriage, moves but also begun its discharging.In this stage, swabbing action is interrupted.
In Fig. 1 C, winding core A2 has carried out the rotation of about 90 degree again with respect to the position among Figure 1B, and the zone that adheres to the initial free edge Li on the fuse begins to rotate around fuse, and in the pressure span of described zone between fuse and rolling surface 15.Fuse A2 continues to roll till it passes roll gap 5 arrival coiling carriages 1,2,3.In the coiling carriage, the shaping that centers on the next reel of fuse A2 is finished, and reel R is discharged by the coiling carriage.
Finish in case center on the coiling of the new reel of fuse A2, repeat aforesaid conversion cycle.
Replace the use adhesive and reach around the shaping of the first lap of fuse around the bonding of fuse, can use one or more groups suitably to be arranged in the zone blow-out nozzle on every side that fuse receives free edge to obtain initial free edge Li.Make this solution become more convenient by the mechanical element that below rolling surface 15, is not used to tear band in setting such as other known devices.For example, nozzle can be arranged on the top of passage 17 and below, described nozzle is suitably led and forces free edge to center on fuse to reel to form first lap, this content will be described with reference to other embodiment in the back.
Fig. 2 A-2D has shown second embodiment according to apparatus of the present invention with corresponding operating order.Identical numerical indication with formerly accompanying drawing 1A-1C in the identical or corresponding parts of those parts.Be with respect to the key distinction of embodiment formerly: distance that increases between the roller 1 and 11 and abutment surface that limits by suction element 23 and belt 13A, increase.In addition, device is roughly the same with operation order.Yet in the example shown in Fig. 2 A-2D, as comparison diagram 2A and 2C as can be seen, before band blocked, fuse had enough to meet the need (complete rotation) in passage 17.The slivering adhesive is indicated by C.When fuse is about to be inserted in the passage 17 (Fig. 2 A), it be positioned such that fuse carry out that appropriateness is rotated and thus at it in passage 17 after the limited distance of feeding-section, described fuse begins to contact with band.Fig. 2 B has shown the moment when slivering adhesive C contacts with band.P still indicates the position of perforation line, and described band will be torn along this perforation line.In Fig. 2 A and 2B, described perforation line is positioned at the upstream of fuse A2.
When winding core A2 is arranged in the position of Fig. 2 B, it with adhesive C-part transfers on the part of band N in perforation line P downstream, band will be blocked and will be positioned near the described line subsequently along this perforation line P.Therefore, the part of adhesive (being indicated by C1 in accompanying drawing subsequently) is transferred on the final free edge of reel R.
In Fig. 2 C, the swabbing action of braking along the band N of perforation line P fracture is begun, described perforation line has surpassed the position of winding core A2 at this moment and has been positioned at the downstream of described winding core with respect to the direction of feed of band.This is because the axis of fuse A2 moves with half speed of band Feeding speed along passage 17, makes that the contact point between fuse A2 and the band N also moves forward with half speed of the Feeding speed that equals perforation line P along passage.In the device shown in Fig. 2 C, slivering adhesive C is positioned at the bottom of fuse.In order to prevent the adhesive rolling surface 15 of between this moving period, making dirty, only need guarantee that surperficial rod separates each other, and slivering adhesive C is blocked at described rod place.
Dotted line among Fig. 2 C is represented the auxiliary adhesive distributing box be made up of swing element 20, and described swing element can be dipped in the adhesive container 22.Swing element is shaped so that it can be inserted between the thin slice that forms surface 15 till it touches fuse A2, so that the specified location on fuse applies an adhesive C, its with C1 in apply in advance and part is transferred to adhesive on the final free edge of the reel that just is being done and overlapped or be positioned at by its.Can obtain two results like this: the quantity of adhesive is resumed and has and those adhesives adhesive of different nature of applying in advance and transfer at least in part on the final free edge is applied in, this is to make it easily to be opened by the end user because the final free edge of reel must cling lightly, and the initial free edge of new reel must use adhesive firmly also promptly to adhere on the new fuse, and described adhesive will glue so that guarantee as far as possible and better cling.
In Fig. 2 D, by the coiling of tearing on the reel R that the final free edge Lf that forms and have an adhesive C1 who is shifted by fuse A2 just finishes to unload from the coiling carriage, and fuse A2 is along passage 17 further feedings, till it makes slivering adhesive C and band contacts for the second time.At this moment, because band N is blocked and swabbing action is no longer carried out above new fuse, initial free edge Li bonds on the fuse and begins the coiling of new reel.Fuse A2 continuous rolling also moves forward up to it along passage 17 and to arrive and surpass roll gap 5, enters till the coiling carriage 1,2,3.
Fig. 3 and 4 has shown the cross-sectional plane of suction element 23 respectively and according to the section of the IV-IV line of Fig. 3.This suction element has suction box 31, and its bottom is limited by wall 33, and band is along the outside face 33A operation of this wall.The outside face of wall 33 forms abutment surface, and band is pressed against on this surface at the winding core that turns round on this surface and be inserted in each change-over period in the passage 17.Wall 33 forms the shell 35 parallel with the direction of feed of band N, and the parallel belts 13A that forms feed component 113 is in this enclosure running.The outside face of belt 13A is a little concordant with the outside face 33A of wall 33 or outstanding slightly.
Between adjacent belt 13A, wall 33 has corresponding perforated portion, promptly has through hole, opening or hole 37.As can seeing among Fig. 4 particularly, be positioned on the height of suction box 31 in-to-in perforated portions at these, be provided with the diaphragm or the thin slice 39 that slide along the direction of feed that is parallel to band N, also be provided with the hole 41 staggered with hole 37.Diaphragm or thin slice 39 forms closed and opens element, and it alternately slides along a direction and another direction, thereby alternately opens and closes hole 37 and make it with the internal communication of suction box 31 or block described the connection.Like this, along with diaphragm 39 alternately moves along a direction and another direction, then activate and remove described swabbing action in timer-operated mode according to the position of the perforation line P that is used to tear band.Suction box 31 inside can remain negative pressure consistently, that is, remain and be lower than bar pressure, thereby even when the coiling cycle utmost point in short-term, also can guarantee the quick connection of aspirating.Negative pressure in the suction box 31 for example keeps by being connected to the vacuum pump, fan or other the suitable aspirator that do not show.
Fig. 5 and 6 has shown a kind of different structure of described suction element.In this case, suction element 23 comprises continuous suction chamber 51, that is, constant the keep-uping pressure of portion is lower than the chamber of bar pressure within it.This chamber can be connected to regularly suction chamber 53 at the setting-up time of determining, the diapire 55 of this suction chamber 53 defines abutment surface 55A, and it has the similar function with above-mentioned abutment walls 33A.Be provided with pedestal 57 in wall 55, the belt 13A that forms feed component 13 turns round in this pedestal.
As seeing among Fig. 6, two plates 61 and 65 can so be located and be made groove 63 and 67 be staggered and two suction chambers 51 and 53 are isolated from each other.In this case, there is not swabbing action to be applied on the band N.This is the setting during the normal winding of reel R.In the time must tearing or block band, portable plate 65 changes into along a direction or another direction according to arrow f65 makes hole or groove 67 aim at (as shown in Figure 6) with groove 63, and thus suction chamber 53 is connected to suction chamber 51.In this set, swabbing action is applied on the band N, thereby brakes band and it is torn.
Fig. 7 shown with Fig. 2 A-2D in the similar embodiment of embodiment.Identical or equivalent parts in two structures of identical numerical indication.Yet in this case, passage 17 has the linear developed surface with rolling surface 15 and take up roll 1 and 2 has identical diameter.This means that winding core can be given straight line path.When the motion of fuse be inserted into their in-to-in axles when controlling this structure particularly favourable, as described in giving an example among the WO-A-02055420.
It also is favourable using airstream under the situation of using adhesive.In fact, they had guaranteed the correct coiling of band to fuse before the rolling of fuse causes vertical slivering adhesive and rolling surface 15 contacts, in case of necessity, the caused airiness of high operating speed by device has caused this fuse partly to expose (that is, not covered by band N).This makes device more reliable, reduced and safeguarded and cleaning, and avoided to rolling surface 15 with comb shaped structure need be to prevent and the contacting of adhesive.
Fig. 8 and 9A-9E have shown (suction and the burst region that are limited to band N) embodiment, and wherein, the initial free edge Li that tears generation by band centers on new fuse A2 coiling and do not use adhesive.Suction element 23 is configured to as the example among Fig. 5.Yet, in this case, in the piece that forms diapire 55, be provided with two groups of nozzles, respectively by 81 and 83 indications.These nozzles differently tilt with respect to surperficial 55A and are arranged on the opposite side of suction socket or groove 59.Below rolling surface 15, be provided with the 3rd group of nozzle by 85 indications.When nozzle 81 and 83 fixedly the time, the nozzle 85 that becomes row is around the transverse axis swing, and described transverse axis is transverse to the direction of feed of band N.Hunting motion shows according to the order of Fig. 9 A-9E.
The operation of installing in the present embodiment is as follows.When fuse A2 was positioned at the upstream of the outlet of nozzle 81 and suction socket 59, described swabbing action was activated and band is torn or blocked at the perforation line P place that is positioned at the positive downstream of suction socket.Nozzle 81 beginnings are blown downwards, and swabbing action is interrupted.By on the whole width of device or the airstream that produces of the nozzle 81 that extends on its major part at least press initial free edge Li, its lower surface 55A from wall 55 is separated.This makes initial free edge reel around new fuse, and simultaneously, new fuse rolls on surface 15 and moves forward.The activation of nozzle 83 is shifted free edge below the fuse onto, and between the latter and surface 15.
The airstream that nozzle 85 produces also causes free edge to be clipped between fuse A2 and the surface 15.When fuse A2 rolling surpasses the vertical surface of the axis of oscillation that comprises bottom oscillating nozzle 85, the latter begins to swing along clockwise direction, thereby the airstream of generation is rotated, make described airstream be properly oriented to promote free edge Li finishes first lap around fuse A2 formation.
When first lap was finished, band N correctly was bonded on the new fuse and begins the coiling of this new reel.
By to the relevant description of use of the airstream that produces by compressed- air atomizer 81,83,85, be noted that, in formed reel, first lap, promptly inner ring is not folding, be that it can not turn back along the direction opposite with the coiling direction of band remainder, as among the embodiment described in the example formerly take place.This is applicable to two kinds of situations, is respectively the reel that does not have center core, promptly have by extracting the situation in the hole that the fuse that can be recycled that can extract reserves, and around the situation that remains on the reel that reel in-to-in fuse forms.In addition, unite the described favorable structure that has obtained reel under the situation of using adhesive and air nozzle equally, obtaining formerly to utilize vertical slivering adhesive to realize impossible favourable outcome when bonding.
Figure 10 A has shown another embodiment according to apparatus of the present invention to 10C.Identical or the equivalent parts of those parts among identical numerical indication and the embodiment formerly.Do not exist suction system and described blocking to block element by machinery and carry out in this embodiment, described machinery blocks element and is positioned at and is sucked in the previous example in the occupied zone of system.This blocks element and comprises that it is positioned to the direction of feed transverse to band N by a pressing element or a series of pressing element of 101 indications, and described band still is directed on the belt 13A that forms flexible member 13.Pressing element is with respect to belt 13A offset placement, so that do not interfere them and from stretching to surface 15 between them.
Operate as follows.At the coiling end of reel R, fuse A2 is inserted into by licker-in roller 19 in the passage that is formed between element 13 and the rolling surface 15, as with reference to as described among the embodiment formerly.When the fuse A2 that on surface 15, rolls when blocking below the element 101, the latter descends so that band pressed to and the fuse A2 in live to transmit.This clamping that has caused band with and along the fracture of perforation line P, this perforation line P is positioned at the downstream of the point of action that blocks element 101.In Figure 10 A, shown the effect of element 101, fuse A2 is positioned such that the vertical line of adhesive C does not also touch band N.Its unexpected rising after the descending motion of element 101 makes it can not hinder the feeding of the initial free edge Li of the band N by tearing generation along perforation line.
Continue the rolling (Figure 10 B) of fuse A2, slivering adhesive A contacts to begin coiling with the initial free edge Li of band N on bonding to fuse A2.In Figure 10 C, fuse continues its rolling and slivering adhesive C is in lower area.Along with the fuse continuous reeling, finished the formation of band first lap, fuse arrives the roll gap 5 between the roller 1 and 2 and enters in the coiling carriage that is formed by roller 1,2 and 3.
In this embodiment, roller 105 matches with roller 11; Described roller 105 rotates with the circumferential velocity of the Feeding speed that equals band N and therefore with the circumferential velocity rotation of roller 11.This layout means, any deceleration (slackening) of the band that causes under pressing element 101 effects can be between roller 11 and 105 is in contact with one another a little propagate upstream.
Figure 11 A-11E has shown another embodiment, the identical or equivalent parts of those parts among wherein identical numerical indication and the embodiment formerly.In the embodiment of Figure 11 A-11E, the structure of winding element substantially with Fig. 2 A-2D in identical.Yet as the situation as shown in Figure 10 A-10C, suction element is blocked element with machinery once more here and is replaced.By the described mechanical element of 111 indications be positioned at be surrounded in flexible member 13 and roller 1 and 11 volume inside and around with the axis X rotation of the parallel axes of roller.In this example, this hand of rotation is opposite with the hand of rotation of roller 1 and 11, i.e. its rotation in a clockwise direction in the accompanying drawings.
In Figure 11 A, the reel R that forms around fuse A1 is arranged in the coiling carriage that is formed by roller 1,2 and 3 and almost finishes.New fuse A2 is pushed among the belt 13A and the passage 17 between the rolling surface 15 that is formed on flexible member 13 by licker-in roller 19.P has indicated the instantaneous position of perforation line, and described band will be along this perforation line fracture.Described position is positioned at the upstream of new fuse A2 position.Block element 111 around himself rotation axis X rotate and pressing element 113 towards the top, promptly be positioned on the opposite side with respect to passage 17.
In Figure 11 B, fuse A2 begins to roll in passage 17 and vertical slivering adhesive C contacts with the band N that is led by flexible member 13, thereby applies the slivering adhesive C1 that is used to be enclosed in the final free edge of tearing back formation.Rotation is blocked element 111 and is continued its rotation.Perforation line P still is positioned at the upstream of fuse A2, and band will be blocked along perforation line.
In Figure 11 C, the fuse that rolls on surface 15 has moved forward farther distance, and perforation line P is positioned at the downstream of fuse A2 and the downstream that slivering adhesive C1 has been applied to described line.The pressing element 113 that element 111 is blocked in rotation will pass between the belt 13A now towards the below.
In Figure 11 D, fuse A2 through below the pressing element 113 in a flash, the surperficial perpendicular position that pressing element 113 is in and is limited along separate routes by the bottom of flexible member 13.Like this, because pressing element 113 (scribbling the elastomeric material with great friction coefficient) stretches out slightly above flexible member 13, band N is clamped between described pressing element and the fuse A2.The speed of element 111 is different from that the speed (in example opposite) of band and this have caused because the over-tension of band and tearing along perforation line P.Figure 11 E has shown that working as element 111 no longer contacts with band N, its final free edge Lf finishes the coiling on reel R and has moment after the slivering adhesive C1, and initial free edge Li begins to reel on new fuse, and slivering adhesive C contacts for the second time with band N.Still the situation as shown in Fig. 2 C can be provided with auxiliary adhesive applicator.
In unaccounted different embodiment, whether no matter be configured to as Figure 10 A-10D or as Figure 11 A-11E, this machinery blocks element can be with respect to the preact that passes through of fuse A2.In this case, it can not produce the effect that hinders fuse A2.Still can utilize the coating with small friction or viscosity, friction material coating and realize tearing of band for example is for example by making the surface of blocking element that contacts with band have extra high friction coefficient.Alternatively, mechanical element can have tip or the pin (pins) that penetrates band, and it keeps band or spurs band along the direction opposite with the direction of feed of band N.This solution can also adopt in the example of Figure 10 A-10C, and wherein moving element can use tip or pin to penetrate band more effectively to stop it or to make its braking.Under any circumstance all motion forward applies delay, braking, maintenance or inhibition to mechanical element to band N, and this effect enough causes tearing of band.On the contrary, when mechanical element rotates as the example among Figure 11 A-11E, may be prescribed as the accelerating action of band applying portion for this mechanical element.For example, mechanical element can rotate, and makes that when it worked to band N, it still moved with higher speed along the direction identical with the latter.By surface and/or a series of tip or the pins that pass band with sufficiently high friction coefficient are provided, band can the clamping point that produces by new fuse A2 and and machinery block tensioning between the contact point of element.Block the realization of tearing by perforation line, by the suitable timing of device, this perforation line is positioned on the part of the band that is subjected to influence of tractive force.
Winding core can be designed as the fuse that can remain in the final products, perhaps can be designed to extract out after the coiling of reel and recycling in case of necessity.The band truncated system in above-mentioned two kinds of situations with the mode effect of equivalence.
Figure 12 A-12E, 13 and 14 has shown another embodiment of the present invention.Be used to indicate identical or equivalent parts with reference number identical in the previous accompanying drawing.The component no longer that has with fwd embodiment is described and can describes with reference to fwd.
Still in this embodiment, at translate phase, promptly, when reel R almost finishes and band N must be blocked to produce and will be wound onto the final free edge on the final reel R and will be wound on free initial line just on the new fuse A that is inserted in the passage 17 when beginning the manufacturing of new reel when reeling beginning, band N block bottom that element 201 is positioned at insertion element 13 along separate routes above.
In the example shown, cam is all arranged with identical angle and is therefore acted on simultaneously and is positioned on the following elastic sheet 203.Yet, arrange that with variable-angle cam or eccentric wheel 207 are possible, make them progressively act on the thin slice, each thin slice is differentially deformed within a certain period of time.This can be used for realizing band fracture progressively, Yi Bian for example carry out to opposite side from beginning, perhaps begins from the center and carries out towards both sides.This fracture method is useful for crash-resistant especially material especially.
As from seeing the accompanying drawing and will specifically illustrating below, the rotation of cam or eccentric wheel 207 causes (in particular moment) thin slice 203 to be bent downwardly, it reaches the inside of passage 17 by this way, and exceed the lower surface of belt 13, change and extend the path of band N, therefore band is torn.
The operation of described device so far is as follows.Figure 12 A has shown strip breaks or has blocked the preceding moment.Soon discharge around the reel R that reels by the winding core of A1 indication, and new fuse A2 is inserted in the passage 17 by licker-in roller 19 from the coiling carriage.
Quicken rapidly, obliquely till contact point up to itself and band N reaches the Feeding speed identical with band itself with belt that forms element 13 and roller 11 contacted fuse A2.
Vertically slivering adhesive C is applied on the surface of fuse, at this moment, and the upstream of the contact point of this slivering adhesive between fuse A2 and band N.
Rolling surface 15 has the insertion of comb shaped structure (or at least one serial recess) to allow licker-in roller 19 to have enough to meet the need and prepare next fuse around its rotation axis.
P indicates the position of the cross-perforating line that is produced by the borer (not shown) on band N, band will be torn along this perforation line.The moment shown in Figure 12 A, described perforation line is positioned at the upstream of fuse A2 and moves forward with band N, because the fuse influence of rolling on fixed surface 15, therefore, the axis that the speed of perforation line is substantially equal to fuse A2 moves forward the twice of speed along passage 17.
In Figure 12 B, fuse begins to roll along passage 17, and while band N reels on reel R continuously and elastic sheet 203 does not reach below the belt 13 yet.
In Figure 12 C, fuse has moved forward the about 1/3 of passage 17 length, and perforation line P has moved to the front (because the Feeding speed of perforation line is the twice of Feeding speed of the axis of fuse A2) of fuse.The moment of fuse from be inserted into passage 17 finished a circle, and slivering adhesive C has touched band N, and the part of adhesive C transferred on the band N, for described purpose, forms slivering adhesive C1 at this.
In Figure 12 D, perforation line P roughly is lower than the free end of elastic sheet 203, and it is pushed downwards in the passage 17 by cam or eccentric wheel 207, reaches under the lower surface of belt 13.
Therefore, because band N follows elastic sheet 203 motions, therefore, the path of the band N between reel R and new fuse A2 is extended.On the other hand, band is maintained on the surface of take up roll 1, and this take up roll scribbles the material with great friction coefficient usually.In the example shown, the reel that just is being done partly leaves from take up roll, and band is around this take up roll running.Yet still for the purpose of improving between band and the take up roll that is adjacent to, it is possible still contacting with take up roll 1 in this stage for reel R.In this case, the reel R that is resisted against on the roller of band N clamps.
Band N also is clamped between the belt 13 and new fuse A2 that forms flexible member, makes it not to be free to slide with respect to elastic sheet 203.Cause the elastic sheet 203 of the extension that elastic deformation allowed that extends beyond band of web path to cause tearing of band or rupture.
The position synchronous of the motion of fuse A2 and elastic sheet 203 and perforation P, band is torn along this perforation P.This tears the initial free edge Li that has produced the final free edge Lf that finishes at the band of reeling on the reel R and will begin to reel on new fuse A2.
Process fuse A2 is to the approaching final free edge Lf of the slivering adhesive C1 (after tearing) on the band N.This part adhesive is used for sealing the final free edge Lf of reel.Still the adhesive that remains in the remainder on the fuse A2 is used for guaranteeing that the band initial portion near limit Li bonds on the new fuse A2.
Adhesive C does not transfer on the band to reel R to be spooled and by the adhesive applicator that is positioned at the rewinding machine downstream final free edge Lf clung also is possible.
Replace other system of adhesive to can be used for beginning the coiling of band around new fuse, for example air nozzle, electrostatic charge or the like.
In case finish the fracture of band, cam 207 continues rotation, away from and cause elastic sheet 203 corresponding returning between the belt 13.Fuse A2 therefore can be free by and move to roll gap 5.Using thin slice to increase the pressure on the fuse A2 also is possible so that improve the bonding of free edge.
Because roller 1 and 11 continuous rotation, after strip breaks, feed component 13 continues to roll and fuse A2 is moved forward along passage 17.
Figure 12 E has shown the discharge phase of reel R, makes 3 acceleration of top take up roll and/or makes following take up roll 2 slow down and reel can be discharged from the coiling carriage.Initial free edge Li begins to reel and elastic sheet 203 turns back to their dead position around fuse A2, with the lower surface of belt 13 concordant (or on them).Fuse A2 will move forward till it passes roll gap 5 and arrives coiling carriage between the roller 1,2,3, and the coiling of new reel on fuse A2 vacated and will be stopped here by this coiling carriage by completed reel R.In case this coiling is finished, aforesaid conversion cycle will repeat.
During in being inserted into passage 17, the relative position between flexible flake 203 and the new winding core A2 can also be chosen and/or adjust according to specific device mode of operation.The length of size and particularly thin slice can also be selected according to the required mode of aforesaid operations performance.In fact, the distortion of deformable elastic sheet 203 can be limited to the zone in new fuse A2 downstream, and perhaps a little significantly the distortion of any also can occur in the zone of fuse or its upstream.The bending of thin slice thus can be to impelling the band braking and the fuse that it is torn being had greater or lesser brake action.If this brake action is optional or useless to tearing of band, being extended in by the path that wafer warpage provided in fuse A2 downstream all is sufficient in any case, wafer warpage can be limited in the downstream of fuse A2 fully, and has the advantage that the band N that avoids the fuse upstream slows down.
Accompanying drawing has just shown specific embodiment of the present invention, and it can change shape and layout in the scope that does not break away from notion of the present invention.The reference number that is occurred in the claims is only for making things convenient for the purpose of its reading according to specification sheets and accompanying drawing, rather than limits its protection domain.
