In addition, being wound around hook part afterwards divides 13ac to become the state tilting with respect to width.Therefore, during carrying these hook parts to divide 13ac towards above-mentioned engaging mechanism 21, revise gradually this inclination and it is disappeared substantially, about each banded delivery section 32,32, implement respectively the work of regulation.; each banded delivery section 32,32 is respectively using a pair of endless belt 33u, 33d as main body; this a pair of endless belt 33u, 33d be configured in side by side with the throughput direction of continuum 13a of strand elastic and the two direction of intersecting of width of serialgram 11,12 on (in the example of Fig. 3, being equivalent to above-below direction); and; poor by this pair of endless belt 33u, 33d each transporting velocity value is each other given, can will divide 13ac to be adapted to and the posture of width almost parallel being wound around each hook part that preliminary phase tilts for width.And, thus, become with each hook part of this width almost parallel and divide 13ac to be installed in serialgram 11,12 each other, overlapping with each surface of serialgram 11,12 and engage.That is, each top of above-mentioned a pair of banded delivery section 32,32 is equivalent to a pair of upper endless belt 33u, 33u, and each bottom of this above-mentioned a pair of banded delivery section 32,32 is equivalent to a pair of lower endless belt 33d, 33d.
And, after this joint, by excision mechanism 51, each end 10je, the 10je of the serialgram 10j excision width from a pair of serialgram 11,12 engages.In addition, now, by this excision, the continuum 13a that clamps and be engaged in the strand elastic between a pair of serialgram 11,12 is also cut off together, thus, each hook part of this continuum 13a is divided 13ac, 13ac ... change into single strand elastic 13,13 ... state.And, by above process, complete telescopic sheet 10.
Below, describe about each structure 21,31,41,51.In addition, in the following description, the continuous direction of serialgram 11,12 is called to " MD direction ", by with the orthogonal direction of this MD direction, the width of serialgram 11,12 is called " CD direction ".In addition, for ease of explanation, three mutually orthogonal directions are defined as to above-below direction, fore-and-aft direction, left and right directions.In addition, in this example, above-below direction is parallel with vertical direction, fore-and-aft direction and left and right directions and horizontal direction parallel.In addition, CD direction and left and right directions are identical directions.And the throughput direction of the continuum 13a of conveying mechanism 31 to strand elastic is parallel with fore-and-aft direction.In addition, CD direction (left and right directions) is suitable with " crisscross " of claim.
< < < engaging mechanism 21 > > >
Engaging mechanism 21 has the 21u of pair of rolls up and down, the 21d that are driven in rotation around rotating shaft C21u, C21d towards CD direction.And the serialgram 11 of the side in a pair of serialgram 11,12 is wrapped in as the top roll 21u of the first roller upper using the winding angle of regulation, in addition, the opposing party's serialgram 12 is wrapped on the lower roll 21d of second roller using the winding angle of regulation.And, serialgram 11,12 is all retained the state roughly relatively not skidding between outer peripheral face 21ua, the 21da of roller 21u, the 21d that should be wound around arbitrarily, thus, follow the driving rotation of each roller 21u, 21d, each serialgram 11,12 becomes roughly one with the outer peripheral face of corresponding roller 21u, 21d, and is transferred along direction of rotation Dcu, the Dcd of this roller 21u, 21d.
And, outer peripheral face 21ua, 21da by pair of rolls 21u, 21d are each other below immediate position Pn(, also be called the position Pn that nips) time, the serialgram 11 of top and serialgram 12 through-thickness of below are that above-below direction is clamped overlappingly, thus, by being coated in advance the bonding agent at least one party who answers overlapping face, both are engaged.In addition, as mentioned above, before this joint, the hook part of the continuum 13a of the strand elastic of elongation state divides 13ac to be put into described a pair of serialgram 11,12 each other along the posture of CD direction (width), so, in the time of above-mentioned joint, the hook part of upper and lower each serialgram 11,12 and the continuum 13a of strand elastic is divided this three of 13ac to be engaged and is integrated.
< < < conveying mechanism 31 > > >
As shown in Figure 3, conveying mechanism 31 has respectively banded delivery section 32,32 in the left and right of CD direction.The mode that each banded delivery section 32 strides across engaging mechanism 21 towards the fore-and-aft direction while about this fore-and-aft direction with its length direction is configured, and thus, strides across the transport path of the continuum 13a of engaging mechanism 21 ground formation linear elastic bodies along fore-and-aft direction.
Each banded delivery section 32 has upper and lower a pair of endless belt 33u, 33d.Each endless belt 33u, 33d are wrapped in respectively on a pair of belt wheel 34u, 34u, 34d, 34d at the both ends that are disposed at fore-and-aft direction.And at least one party's belt wheel 34u, 34d is attached at as servomotor 35u, the 35d of drive source upper, thus, can set respectively circular velocity value to each endless belt 33u, 33d.
In addition, according to belt wheel 34u, 34u, 34d, 34d towards setting, the surround orbit of each endless belt 33u, 33d has and is positioned at the distolateral distolateral track Tr1 of CD direction and is positioned at the center side track Tr2 by the center side of CD direction than distolateral track Tr1.And, in distolateral track Tr1, each endless belt 33u, the 33d forwards, backwards front of direction move, other direction, in center side track Tr2, rearward move, thus, the continuum 13a that is wrapped in the strand elastic in a pair of banded delivery section 32,32 is kept by endless belt 33u, 33d, 33u, 33d mobile on distolateral track Tr1, thus, also finally arrived engaging mechanism 21 by the front conveying of direction forwards, backwards.
In addition, the zone face of endless belt 33u, 33d towards being to become the be oriented basis parallel with CD direction with the normal direction of this face, also can be according to circumstances, this normal direction from CD direction for example to be greater than 0 ° of angular range that is less than 60 ° tilted.
< < < winding mechanism 41 > > >
As shown in Figure 3, winding mechanism 41 is wrapped in the continuum 13a of strand elastic the suitable winding parts such as bobbin with coiled type from the coil case 13C(of strand elastic) emit the continuum 13a of strand elastic, meanwhile, be wrapped in the rearward end 31b of conveying mechanism 31.Therefore, this winding mechanism 41 has: emit portion 43, emit the continuum 13a of strand elastic from the coil case 13C that can rotate freely the strand elastic that floor-covering roll cylinder mechanism 42 supports; Wound portion 46, is wrapped in the continuum 13a of the strand elastic of emitting from the portion of emitting 43 the rearward end 31b of conveying mechanism 31.
Emitting portion 43 emits the continuum 13a of strand elastic and the tension force of this continuum 13a is set in the tension range of regulation from the coil case 13C being arranged on drum mechanism built 42, afterwards, with the feed speed value (m/ divides) of the regulation corresponding with this speed of wrap value, the continuum 13a of strand elastic is supplied with to wound portion 46 linkedly with the speed of wrap value (m/ divides) of wound portion 46.
Here, the minimum tension force in the unflagging scope of continuum 13a of mentioned strain scope based on strand elastic is preset, for example 0.0298N～0.098N.And thus, substantially, the speed of wrap value of wound portion 46 becomes the elongation multiplying power of the continuum 13a of the strand elastic in the winding moment being wrapped on conveying mechanism 31 with respect to the ratio of the feed speed value of the portion of emitting 43.Therefore, adjust linkedly feed speed value with speed of wrap value, thus, can roughly with the elongation multiplying power of target, the continuum 13a of strand elastic be wrapped on conveying mechanism 31 all the time.In addition, the continuum 13a that elongation multiplying power refers to strand elastic is in be elongated to the index of the state of several times from its natural length, and the business who for example obtains divided by natural length LO as the length L S with elongation state (=LS/LO) represents.
As described concrete structure example of emitting portion 43, can be listed below structure, it has: the continuum 13a of strand elastic from the coil case 13C of drum mechanism built 42 to the feed path of wound portion 46, be arranged on the position of upstream side, approach the position tension controller 44 of coil case 13C; Donor rollers 45, is arranged on the position of ratio tension controller 44 downstreams in this feed path, approaches the position of wound portion 46.Here, the mode that tension controller 44 converges on the tension force of the continuum 13a of the strand elastic of its nearest downstream position in the tension range of regulation is carried out feedback control to the discharging amount from coil case 13C, as its concrete structure example, have: sensor 44s, measures the tension force of above-mentioned nearest downstream position; Emit and use driving pulley 44p, be arranged on the position by the upstream side of driving path than the measuring position of this sensor 44s.And emitting with the drive source of driving pulley 44p is that servomotor (not shown) is controlled by suitable control device, thereby the measured value of the tension force of exporting from sensor 44s converges on above-mentioned predefined tension range.
Fig. 5 is the summary central cross-sectional view of wound portion 46.As shown in Figure 5, wound portion 46 taking approach conveying mechanism 31 rearward end 31b configure have round-ended cylinder parts 46a as main body.The cylinder axle C46a that has round-ended cylinder parts 46a be set in the osculum kernel of section position of conveying mechanism 31, with the cross section being specified by above-below direction and CD direction on the axle C46a of roughly the same position, center, and, be the axle C46a setting substantially in parallel with fore-and-aft direction.And, drive rotation to have round-ended cylinder parts 46a around this axle C46a.This drive source uses for example servomotor 49m.; in the example of Fig. 5; rearward be wholely set highlightedly coaxially path cylinder 47 from the bottom 46ab that has round-ended cylinder parts 46a with cylinder axle C46a; fixed drive belt wheel 49p coaxially on described path cylinder 47, the driving spinning movement of the driving rotating shaft 49s of servomotor 49m is transfused to this driving belt wheel 49p by timing belt 49b.And, thus, there is round-ended cylinder parts 46a to drive rotation.
In addition, in the multiple positions that have in round-ended cylinder parts 46a, be provided with pulley 48p, 48p, the 48p of the continuum 13a that is wound around strand elastic.These pulleys 48p, 48p, 48p be by from the portion of emitting 43 with transport condition to the continuum 13a of the strand elastic that has round-ended cylinder parts 46a to supply with to the guiding parts of throw-in part 48t guiding that is arranged on the conveying mechanism 31 the leading section 46af of round-ended cylinder parts 46a.
Specifically, pulley 48p, 48p, 48p are separately positioned on the front position of the inner circumferential side of path cylinder 47, the back-end location of cylindrical portion 46at that has round-ended cylinder parts 46a and the front position of this cylindrical portion 46at, and, in this front position, be provided with in addition to drop into as above-mentioned throw-in part 48t and use pulley 48t.
And the continuum 13a of the strand elastic of supplying with from the portion of emitting 43 is wrapped in each pulley 48p, 48p, 48p with said sequence, thus, the continuum 13a of strand elastic arrives above-mentioned throw-in part 48t as described below.; first; the continuum 13a of the strand elastic being supplied to from the portion of emitting 43 arrives the front position of this path cylinder 47 by the inner circumferential side of path cylinder 47; then; by the pulley 48p of this position, travel direction is transformed into round-ended cylinder parts 46a radial direction outside and travel along the bottom 46ab that has round-ended cylinder parts 46a.And, travel by this, arriving this has the back-end location of the cylindrical portion 46at of round-ended cylinder parts 46a, but by the pulley 48p of this back-end location, again travel direction is transformed into front and arrives the front position of this cylindrical portion 46at.And, finally, be directed to the throw-in part 48t of this position by the pulley 48p of this front position.
In addition, throw-in part 48t drops into and is configured to and has the cylinder axle C46a of round-ended cylinder parts 46a parallel with the rotating shaft C48t of pulley 48t self.Therefore, this pulley 48t can smooth and easy and promptly have the rearward end 31b inner circumferential side of round-ended cylinder parts 46a, conveying mechanism 31 to drop into towards being positioned at the continuum 13a of strand elastic.
In addition, about the position of fore-and-aft direction, there are the leading section 46af of round-ended cylinder parts 46a and the rearward end 31b of conveying mechanism 31 overlapping., the rearward end 31b of conveying mechanism 31 has in round-ended cylinder parts 46a from there being the leading section 46af of round-ended cylinder parts 46a to be inserted into this.Therefore, the continuum 13a of the strand elastic that can reliably the throw-in part 48t from front position be put into the rearward end 31b of conveying mechanism 31, is wrapped in the periphery of the rearward end 31b of conveying mechanism 31.
< < < excises the 51 > > > of mechanism
Fig. 5 A and Fig. 6 B are the key diagrams of excision mechanism 51.Fig. 5 A is the summary side view that is provided with the engaging mechanism 21 of excision mechanism, and Fig. 5 B is the B-B direction view of Fig. 5 A.Fig. 6 A is the VI-VI direction view in Fig. 5 A, and Fig. 6 B is the B-B direction view in Fig. 6 A.
Top roll 21u in the 21u of pair of rolls up and down, 21d that excision mechanism 51 has with respect to engaging mechanism 21 arranges.Specifically, excision mechanism 51 is relative with the outer peripheral face 21ua of top roll 21u, has corresponding to serialgram 11(or 12) each end 11e, 11e(or 12e, 12e) configuration a pair of blade member 52,52 and correspond respectively to the slot part 53,53 of a pair of ring-type on these a pair of blade member 52,52 ground are formed on top roll 21u outer peripheral face 21ua along circumferential (direction of rotation Dcu).And, in a pair of slot part 53,53, be inserted with respectively the point of a knife 52e of the corresponding blade member 52 in a pair of blade member 52,52.In addition, this point of a knife 52e is set in than the above-mentioned position Pn position of downstream a little of nipping to the on position of slot part 53 on the direction of rotation Dcu of top roll 21u.In addition, on the outer peripheral face 21ua of top roll 21u, be wound with at engaged a pair of serialgram 11,12 when nipping position Pn, the serialgram 10j after this pair of serialgram 11,12 engages roughly moves along direction of rotation Dcu with outer peripheral face 21ua integratedly by the rotary actuation of top roll 21u.Thus,, by each point of a knife 52e, the 52e of a pair of blade member 52,52, each end 10je, the 10je of the serialgram 10j after joint are cut off when the position of the serialgram 10j after this joint by a pair of blade member 52,52 the.
In addition, as shown in Figure 5 B, in the time of this cut-out, the serialgram 10j after not only engaging, the continuum 13a of strand elastic is also cut off in the same position of CD direction by point of a knife 52e, the 52e of above-mentioned blade member 52,52 simultaneously.And thus, each hook part of the continuum 13a of strand elastic is divided 13ac, 13ac ... change into respectively single strand elastic 13,13 ..., cut off and generate single strand elastic 13,13 by the continuum 13a of strand elastic ..., the strand elastic 13,13 that this is single ... be the state of a pair of serialgram 11,12 in the serialgram 10j only belonging to after joint.
Here, as mentioned above, it is an identical cut-out action that the cut-out of the excision processing of the end 10je of the serialgram 10j after joint and the continuum 13a of strand elastic is processed the two., the cut-out of the excision processing of the end 10je of this serialgram 10j and the continuum 13a of strand elastic is processed and is carried out completely simultaneously.Therefore,, before the excision of the end of serialgram 10j 10je is processed, strand elastic is the state in continuum 13a also.In addition, now, in the continuum 13a of strand elastic, the part suitable with each single strand elastic 13,13 is that each hook part is divided 13ac, 13ac ... a pair of banded delivery section 32,32 by conveying mechanism 31 is in the state being stretched in CD direction, under this elongation state, each hook part is divided 13ac, 13ac ... roughly alignment each other.And under this state, the end 10je of the serialgram 10j after connection is cut.
Therefore, following phenomenon is suppressed effectively: the inconsistent phenomenon of the size of the telescopic sheet 10 illustrating above with reference to Figure 1B, the single strand elastic 13,13 having produced while excising end 10me ... between inconsistent the caused excision of elongation state after and remove the inconsistent phenomenon of width size of the telescopic sheet 10 of obviousization after elongation state.As a result, can make the outward appearance of telescopic sheet 10 of end-state good.
In addition, from Fig. 5 A and Fig. 5 B, in this example, use rotation sword 52 as blade member 52.Rotation sword 52 is for example disc parts 52 of positive toroidal, and its outer peripheral edges 52e becomes point of a knife 52e in all-round scope.And rotation sword 52 has the spindle unit 52s coaxially and integratedly arranging with its center of circle C52, this spindle unit 52s is parallel with the rotating shaft C21u of top roll 21u.And using this spindle unit 52s as rotating shaft C52, rotation sword 52 rotates.
In more detail, this spindle unit 52s can rotate freely on the suitable fixed class parts 55 that are supported in production line by not shown bearing.In addition, in described spindle unit 52S, be endowed driving revolving force from the not shown servomotor as drive source by the suitable not shown drive mechanism such as belt wheel and timing belt, thus, rotation sword 52 drives rotation.Therefore, bring into play high cuttability.
And as shown in Figure 5A, in this example, the rotation direction of rotation of sword 52 and the direction of rotation Dcu of top roll 21u are in the same way.That is, top roll 21u is rotated counterclockwise, and with it matchingly, rotation sword 52 is also rotated counterclockwise.And, thus, cutting off the position Pc(of each end 10je of serialgram 10j hereinafter referred to as off-position Pc) moving direction of outer peripheral edges 52e of rotation sword 52 located is contrary with the moving direction of the outer peripheral face 21ua of top roll 21u.Thus, be that in the process that moves towards the direction contrary with the moving direction of serialgram 10j of point of a knife 52e, the end 10je of serialgram 10j is cut off at the outer peripheral edges 52e of rotation sword 52.
And, according to such cut-out mode, side by side carry out the cut-out of the continuum 13a of strand elastic with the excision of end 10je, can obtain high cuttability, its result, as in the present embodiment, even the continuum 13a of strand elastic that there is hard-to-break at serialgram 10j, also can excise with high cuttability the end 10je of this serialgram 10j.Specifically, as described below.
First, the in general non-constant of cuttability of parts 13a as the continuum 13a of the strand elastic of present embodiment, that multiple elastic yarns are bonded into pencil.But in the time cutting off under the effect of large tension force, these parts 13a ratio is easier to be cut off.
About this point, according to the relation of direction of rotation as described above, the point of a knife 52e that rotates sword 52 with respect to the moving direction of serialgram 10j moves round about.Therefore,, when the continuum 13a of strand elastic is cut off, large tension force acts on this continuum 13a.Therefore, can realize the raising of the cuttability of the continuum 13a of strand elastic, consequently, there is high hard-to-break even if there is the serialgram 10j of the continuum 13a of the strand elastic of this hard-to-break, also end 10je can be excised.
But, direction of rotation towards being not limited to this., also can make to rotate sword 52 to the direction rotation of above-mentioned opposite direction.The direction of rotation that, can make to rotate sword 52 is the rightabout of the direction of rotation Dcu of top roll 21u.
In addition, in this example, as shown in Figure 5 B, the point of a knife 52e of the rotation sword 52 in the slot part 53 of the outer peripheral face 21ua of insertion top roll 21u forms as follows,, not with together with the bottom surface of slot part 53, clamp a pair of serialgram 11,12 in conjunction with after serialgram 10j cut off., set the depth dimensions (mm) of slot part 53 and the point of a knife 52e insertion (mm) to slot part 53, thereby suitably have gap between the serialgram 10j in cutting-off process and the bottom surface of slot part 53.Therefore, can suppress the wearing and tearing of the point of a knife 52e that rotates sword 52, its result, can make to rotate sword 52 long lifetimes.
As an example of described rotation sword 52, can illustrate the rotation sword of for example ultramicron superhard (Super micro-gain carbide) system, more particularly, can illustrate Kyoto Ceramic Co., Ltd's rounding cutter (production code member FRC28L, 40 ° of the basils).
In addition, about the point of a knife shape of rotation sword 52, can be also any one of a sword and two-edged,, as shown in Figure 5 B, use two-edged here.But, about the basil, compared with the little basil such with 10 ° or 20 ° etc., preferably 40 ° of above so large basils, if like this, in the case of the rotation sword 52 of the superhard system of above-mentioned ultramicron, the ultramicron that is embedded in a large amount of high rigidity in the mother metal of point of a knife 52e is difficult to come off from mother metal, its result, realizes the long lifetime that rotates sword 52.
In addition, the peripheral speed value (m/ divides) of rotation sword 52, the rotary speed value (m/ divides) at point of a knife 52e place with the balance of cuttability by experiment or the suitably decision such as trial run.And, for example, if the peripheral speed value of rotation sword 52 is set for to the more than 1.5 times of peripheral speed value (m/ divides) of top roll 21u, can bring into play good cuttability.
In addition, following structure also can improve cuttability effectively.That is, as shown in Figure 5A, at the above-mentioned off-position Pc of the outer peripheral face 21ua of top roll 21u, the state of the serialgram 10j after a pair of serialgram 11,12 engages in contacting and reel with the outer peripheral face 21ua face of top roll 21u.Therefore, due to and this outer peripheral face 21ua between frictional force, serialgram 10j is kept, that is, the movement of the CD direction of serialgram 10j is limited.
Therefore, can effectively be suppressed at serialgram 10j while cut-out and enter and dodge the situation in slot part 53, consequently, rotation sword 52 can be brought into play higher cuttability.In addition, in order to improve the retentivity of outer peripheral face 21ua of top roll 21u, cover this outer peripheral face 21ua with the high material of frictional force, as an example of this material, can enumerate silicon is the plasma overlay film of cladding material.
As shown in Fig. 5 A and Fig. 6 A, by the excision cut each end 10je of mechanism 51, the form that 10je becomes continuous strip-shaped members, the recovering mechanism 58 that reclaims this end 10je arranges in the mode of the excision mechanism 51 that approaches top roll 21u.This recovering mechanism 58 for example has respectively suction port 58h, 58h accordingly with a pair of blade member 52,52.And each suction port 58h produces captivation by sucking ambient air.Therefore near the suction port 58h of the each end 10je, having been excised by each blade member 52 being absorbed into separately is also recovered.
But as shown in Figure 6 A and 6 B, each end 10je is at this moment upper, generates single strand elastic 13,13 at the continuum 13a by strand elastic ... time end material 13r, the 13r of ring-type that produce ... engage integratedly.And, make the each banded delivery section 32,32 of conveying mechanism 31 by end material 13r, the 13r of this ring-type ... inner circumferential side.Therefore,, in the time not cutting off these end materials 13r, 13r, can not reclaim each end 10je by above-mentioned recovering mechanism 58.
Therefore, in the present embodiment, the assigned position between rotation sword 52 and the suction port 58h of recovering mechanism 58, for cutting off end material 13r, 13r ... shut-off mechanism 61,61 and each end 10je, 10je configure accordingly.And, in this example, dispose dead knife 62 as this shut-off mechanism 61.Therefore, be engaged in integratedly each end material 13r, the 13r of the ring-type of end 10je ... in the time of the allocation position by this dead knife 62, this end material 13r, 13r ... cut off in turn, the form of ring-type is disengaged.Thus, end material 13r, 13r ... depart from from banded delivery section 32 rapidly.Then, consequently, can reclaim rapidly end 10je by recovering mechanism 58.
Here, about the reason of needs shut-off mechanism 61 as above, do following consideration, this reason is, the continuum 13a of strand elastic is engaged in each end 10je of serialgram 10j, therefore, and on cut end 10je, the end material 13r of strand elastic exists with the form of ring-type, and this is can not depart from because card hangs over banded delivery section 32.
Therefore,, if made an effort on the coating zone of the binding agent of the joint use on a pair of serialgram 11,12 of the not engagement state before the serialgram 10j becoming after joint, can omit above-mentioned shut-off mechanism 61., at the region suitable with the end 10je having excised, coated with adhesive not.Specifically, as described below.
Above-mentioned binding agent is substantially in the position that is positioned at the upstream side of direction of rotation Dcu, Dcd than the position Pn that nips of engaging mechanism 21, be coated on the surface of serialgram of at least one party in a pair of serialgram 11,12, in the time applying, as shown in the summary top view of Fig. 7, using the region suitable with each end 10je in above-mentioned surface as non-coating zone, only using than this pair of non-coating zone by the region of the center side of CD direction as applying subject area coated with adhesive.
And, like this, a pair of serialgram 11,12 is engaged each other and the serialgram 10j that forms is not engaged at each end 10je, so, in the moment of cutting off each end 10je from serialgram 10j by excision mechanism 51, in cut end 10je, 10je, end material 13r, the 13r of the end of serialgram 11, the end of serialgram 12 and strand elastic ... this three disassembles naturally.Therefore, each end of these serialgrams 11,12 and end material 13r separate from banded delivery section 32 naturally, are recovered mechanism 58 and reclaim rapidly.
