Preferably, described cord tape is wirecord fabric or fabric cord.
By in splicing apparatus of the present invention, be provided with at least two measurement mechanisms, the arris measuring the cord strip of splicing by means of described measurement mechanism extends trend.These two measurement mechanisms are positioned at such position, and on this position, tape is spliced, and therefore measurement mechanism is connected to described concatenation unit downstream.Now, by (aufgenommenen) measuring-signal by measurement mechanism record/record, can detect the corresponding extension trend of longitudinal edges on the one hand, possible offsetting, the namely arris that therefore also must detect transversely is beated but then.Measuring-signal is such as provided to an independent control treatment device arranged to the control treatment device of measurement mechanism or a higher level, and this control treatment device correspondingly processes measuring-signal and determines offsetting value or offsetting information according to measuring-signal.According to this determination result how, various different situation can be produced.If do not find to offset, then longitudinal edges is accurately mutually concordant with the cord tape spliced before.If all detect offsetting in side or in both sides, then a kind of possibility be this offsetting also within the margin of tolerance, that is, it be acceptable, be in width within required tolerance and change.In addition but also may be, the offsetting value recorded be greater than the corresponding margin of tolerance.This can be this situation, that is, the cord tape of new splicing cord strip bar that is narrower than the cord tape spliced before than the cord tape of wider, the new splicing of the cord tape spliced before or new splicing such as laterally offsets in one direction when width is identical.Depend on the circumstances that to draw in corresponding longitudinal edges region be positive or be that negative arris is beated or laterally offsets.According to this determination result, namely about the offsetting value of each longitudinal edges side, control device controls alignment means now in this wise, make by the new cord tape to be spliced be such as just transported to of this alignment means correction, even if therefore also its lateral transfer slightly, to make two cord tapes again locate relative to each other like this in arris side in order to follow-up splicing, making to offset is within tolerance again.At this, alignment means can comprise grabbing device,---especially servomotor or stepper motor---is at least also regulating in the conveying direction perpendicular on the direction of throughput direction, preferably can catch cord tape by grabbing device, and grabbing device to be by electric driver.Therefore grabbing device or clamp is adopted, as described in exemplarily in DE4309013A1.Now, the longitudinal edges of new cord tape to be spliced can be caught and lateral transfer cord tape slightly, to make cord band align by this grabbing device.How process depending on arris location realizes, and this grabbing device only moves upward in the side perpendicular to throughput direction may be just enough.But, if cord tape is placed in stitching position by the conveying campaign of level, as such as in the docking facilities known by DE4309013A1, then suitablely be, grabbing device additionally also can move in the conveying direction, therefore also namely slightly can move with caught cord tape.The electric driver of grabbing device is preferably designed for servomotor or stepper motor, and this makes it possible to realize the very fast and accurate control of grabbing device or motion.
Because by splicing apparatus of the present invention, two measurement mechanisms are connected to the downstream of concatenation unit, therefore preferably can detect immediately continuously after corresponding band is measured and stitching error that corresponding correction may exist or the offsetting that no longer meets tolerance.Therefore, measurement mechanism is between concatenation unit and the winding station being connected to downstream, and the cord strip of splicing is with or is laid on station and be wound on this winding station or in the device such as static roller/damping roll, vertical off line, the maintenance that are connected to this upstream, winding station.But measurement mechanism is preferably as far as possible near concatenation unit.
As mentioned above, the control rapidly of splicing connection can be realized at this and automatically adjust again (see above-mentioned design) immediately when offsetting excessive.Directly after generation splicing, detect possible mistake, thus responsively directly can revise accordingly, therefore can avoid the generation of scratch tape.
Measurement mechanism is definitely a critical elements in longitudinal edges detects.Can use such measurement mechanism, it comprises the rectilinear transducer with the light source arranged, and wherein, rectilinear transducer is arranged perpendicular to the throughput direction of cord strip and provides the measuring-signal relevant with the position of longitudinal edges.This rectilinear transducer comprises the single optical pickocff of the straight line setting along regulation.This rectilinear transducer is equipped with light source, such as, be equally also line source, and it is parallel to straight line optical sensor and extends.Cord strip is such as irradiated from below or from top by this light source, and straight line optical sensor such as detects is with by (cord) the corresponding reverberation reflected.Obtain a measuring-signal, this measuring-signal demonstrates gem-pure arris, and it accurately corresponds to longitudinal edges position.This measuring-signal is correspondingly analyzed, and which defines the position of longitudinal edges, fixes because rectilinear transducer is position.Measuring-signal is recorded continuously, namely constantly, but such as periodically (getaktet) is read, that is, such as every 10ms or---illustrating following also going deep into---are being with the delivered length record of controllably every 0.2mm in delivered length or are reading a corresponding measuring-signal.Therefore, give very high measurement speed by this rectilinear transducer, this is also finally needs, because cord strip transporting velocity is still quite high.
As using the alternative of this rectilinear transducer it is contemplated that, using video camera as measurement mechanism, the image analysis of this video camera being detected to the position of longitudinal edges.This video camera (being such as CCD-video camera) therefore takes the image of cord strip in longitudinal edges region continuously.By with the corresponding analysis software of simple arris probe algorithm work, in each camera review to be analyzed, accurately longitudinal edges can be detected now.Also can obtain corresponding offsetting information thus, then this offsetting information is by the basis of control needed if desired as alignment means.
In principle, the coverage of rectilinear transducer long enough or video camera is enough large, and corresponding measurement mechanism position regularly, namely can not adjustably be arranged just enough transverse to throughput direction.Because like this corresponding measurement category large must being enough to can by same measurement structure detection or the offsetting of cord strip controlling different in width.But suitable, because frequent working width is at the cord strip of 100mm to 1000mm in tire industry, measurement mechanism is arranged to can regulate by straight line perpendicular on the direction of throughput direction.This provide this possibility, that is, corresponding measurement mechanism (be such as the rectilinear transducer with light source, or video camera) can move transverse to throughput direction, and locking again on the position of hope, makes it possible to make a response to the bandwidth of change.
This located lateral can manually be carried out.But, in order to automatically carry out this process, suitable is, at least arrange one in the both sides of cord strip respectively and be resisted against roller on cord strip or a guide plate, roller or guide plate are used for guiding band, and wherein, roller or guide plate are can supported perpendicular to the mode of rectilinear motion on the direction of throughput direction, and wherein, measurement mechanism and corresponding roller or guide plate move and are coupled.When this namely side guiding device arranged by two rollers (at wirecord fabric) or guide plate (at fabric cord), this side guiding device is resisted against on cord strip longitudinal edges with little pressure.Now, if width changes, roller or guide plate must be driven together to flank movement.Because corresponding measurement mechanism and roller or guide plate or linear guiding device move be coupled, therefore measurement mechanism also must be shifted along identical direction, makes finally to follow the trail of thus the measurement category of measurement mechanism and makes it automatically arrange corresponding to the cord strip width of change again.Certainly, selecting design structure like this, that is, is not the adjustment that each minimum width fluctuations can cause measurement mechanism, but when only bandwidth changes, corresponding difference in size special talent greatly causes the adjustment of measurement mechanism.
As already described, it is contemplated that, two cord tapes offset in a different manner relative to each other.When detecting the offsetting of both sides, if obtain the offsetting of plus or minus in both sides, also may be different offsettings if desired, now can control alignment means like this, making this alignment means cord tape moved the mean value obtained by two offsetting values.Namely control treatment device is considered two offsetting values and in simple calculating, is obtained mean value by described offsetting value.Can suppose at this, an offsetting provides positive offsetting value in one direction, and an offsetting provides negative offsetting value in the opposite direction.If such as two longitudinal edges in a same direction relatively before the longitudinal edges of cord tape of splicing offset, then two offsetting values are positive or are negative, therefore by simply adding up and halving with value, corresponding correction offsetting value can be obtained.Then cord tape is certainly made to move along contrary direction.Such as, but if two offsettings are contrary, before cord tape newly to be spliced compares on two longitudinal edges, the cord tape of splicing is wider or narrower, then an offsetting value is positive, and another is negative.Also can determine to revise offsetting value by second-class the assigning to of simple cumulative sum in this case.
If rectilinear transducer detects as measurement mechanism, then rectilinear transducer detects corresponding longitudinal edges continuously and therefore provides lasting measuring-signal (yes relevant with corresponding reading beat) to control treatment device, this measuring-signal give through the position of longitudinal edges.Because longitudinal edges or strip width are owing to being the rubber mass of flexible, viscosity and the width fluctuations that has slightly, thus according to two directly measured values in succession determine to offset and cause little offsetting all the time.Therefore suitable, considering multiple single measuring-signal when analyzing, finally also namely monitoring certain longitudinal edges length and carrying out offsetting control or offset determining based on this.For this purpose, the described control treatment device of such design, namely, this control treatment device analyzes the measuring-signal (in these signals when the measuring-signal that increase by is new cancellation the oldest corresponding measuring-signal) of specified quantity like this, make to be formed the first set of signals of comprising multiple older measuring-signal and comprise the secondary signal collection of multiple newer measuring-signal and form measuring-signal mean value in each set of signals, wherein, possible offsetting is provided when there is different measuring-signal mean value.Therefore, two longitudinal edges portion sections or its position compare by control treatment device mutually.For this purpose, control treatment device forms by the measuring-signal quantity mainly will considered specifically, in the signal processing the set of signals that two comprise certain number of signals respectively.Now, by these signal determination measuring-signal mean value.Owing to defining mean value, therefore common arris fluctuation does not play an important role.Now, in this side of control device, determined measurement signal value compared mutually and carry out offsetting based on this and determine.
At this, according to the particularly advantageous expansion design of one of the present invention, the quantity of the measuring-signal comprised by two set of signals is confirmed as: the measuring-signal be not considered when signal transacting having some between two set of signals, wherein, the quantity of these measuring-signals is corresponding to the distance of the regulation of cord strip.That is, two set of signals are made up of the measuring-signal recorded spaced reciprocally in time.Suppose, specified quantity, overall that considered by control treatment device or as analysis foundation measuring-signal is 100 signals recorded successively.Then, such as the oldest form two set of signals and calculate corresponding signal averaging according to these measuring-signals with 30 up-to-date measuring-signals by 30.Now, between these two set of signals, such as also have 40 measuring-signals, these measuring-signals correspond to the arris length of regulation, and these 40 measuring-signals are not considered in analysis.That is, see that spaced arris portion section compares mutually in the conveying direction for two the most at last, between these two arris portion sections that is the gap had by the definition of measuring-signal quantity between set of signals.This gap and the quantity of measuring-signal be not considered should be confirmed as, and make the arris length during it is more given than the splicing angle of mutually splicing according to cord tape, that tilt to extend, splicing offsets longer.Because this causes, then such situation is under any circumstance formed, that is: a set of signals is only made up of the measuring-signal that the cord tape spliced " older " detects, and another set of signals is made up of the measuring-signal that the cord tape spliced in " newer " detects.Therefore, in offsetting one timing, obtain enough significantly signal averaging and jump, this signal averaging jumps and accurately describes offsetting.Arris region that splicing connecting portion medium dip extends, dislocation and the measuring-signal that records there be not during therefore particularly advantageously entering signal mean value is formed in this case.
Especially, when cord strip is transmitted with identical and constant speed all the time, corresponding number of signals can almost be determined regularly.Detect because then can set like this and read the beat (Taktung) of measuring-signal, making it possible to detect and determine or be equivalent to carry section accordingly and the respective numbers therefore determining or be equivalent to corresponding longitudinal edges length.Transporting velocity is determined by the transporting velocity of the conveying device of convoying curtain tape.But occur sometimes: the actual motion speed of the cord strip be made up of the elastic caoutchouc matrix of viscosity is as mentioned above slightly larger than the transporting velocity of conveyer belt itself.Suitable in this case, be connected with the distance measurement device of the conveying distance detecting cord tape at least one measurement mechanism upstream or downstream, wherein, by this side of control treatment device by corresponding with commute information for the measuring-signal recorded successively.Can realize temporal parsing thus, mode is: make the measuring-signal that records successively corresponding with corresponding commute information.That preferred use has the meter wheel be placed on belt surface, that form is rotary encoder system measurement mechanism.At this, meter wheel is a part for encoder, and this encoder provides the signal of the determination relevant with distance, and this signal is corresponding with detected measuring-signal, makes it possible to measuring-signal to be also therefore associated with longitudinal edges position with transporting velocity.
Can also be reacted to the velocity variations in band conveying by this commute information, mode is: determine the quantity of considered measuring-signal according to the commute information detected or treat the selection of measuring-signal of consideration.If transporting velocity changes, then suitable, in the category of analysis that offsets, form the quantity of the measuring-signal of corresponding measuring-signal collection by adaptation or consider this point by corresponding selection for the measuring-signal forming measuring-signal collection.If such as transporting velocity reduces significantly, then, when the beat that measuring-signal detects keeps identical and quantity keeps identical, compared with higher transporting velocity, corresponding measuring-signal collection only describes very short longitudinal edges portion section.Therefore, when understanding actual transporting velocity, based on commute information, the number of signals can treating consideration carries out corresponding adaptation, but also can change signal timing if desired, namely records the time series of measuring-signal.Also can imagine as alternative, determine the selection of the measuring-signal treating consideration when beat keeps identical according to the commute information detected.Because measuring-signal is detected with identical beat, but obviously " narrower " be recorded about longitudinal edges position due to significantly lower transporting velocity, therefore can pass through the formation of interferometry set of signals according to the corresponding selection of commute information and by corresponding measuring-signal collection definition, there is the longitudinal edges length of wishing length, or possibility respective settings can certainly be followed the trail of or keep the respective clearance between measuring-signal collection by various correction.
Except pressing splicing apparatus of the present invention, a kind of method using the splicing apparatus of described type to detect and revise the offsetting of two cord tape, especially wirecord fabrics mutually spliced or fabric cord is also provided, the salient point of the method is, the corresponding extension trend of two longitudinal edges of the cord strip of splicing is detected by means of at least two measurement mechanisms, and according to the offsetting of independent testing result by means of the longitudinal edges at control treatment device determination splicing regions place, this control treatment device controls alignment means to revise offsetting according to testing result.
As measurement mechanism or the rectilinear transducer that can use the light source with arranging, preferred line source, wherein, rectilinear transducer is arranged perpendicular to the throughput direction of cord strip, and provides the measuring-signal relevant with the position of corresponding longitudinal edges.Rectilinear transducer and line source are preferably arranged in parallel to each other, and therefore sent beam orthogonal sends in material web.Therefore beat can not enter into measuring-signal with the height of the web be conveyed through along measurement mechanism at a high speed.The high measurement frequency of this sensor also allows to detect and moves fast.The measurement category of this sensor such as can until 30mm be wide.The opposite outer light of sensor own is protected.Rectilinear transducer preferably measures corresponding longitudinal edges continuously, and provide measuring-signal continuously to control treatment device, this control treatment device can be independent, arrange to the control treatment device of measurement mechanism or higher level, the device of the operation that controls whole splicing apparatus.Such design con-trol treating apparatus, namely, the measuring-signal of such selection specified quantity (in these signals when the measuring-signal that increase by is new the corresponding measuring-signal the earliest of cancellation), the secondary signal collection of the first set of signals making to be formed the measuring-signal comparatively early comprising some and the newer measuring-signal comprising some, and form measuring-signal mean value in corresponding set of signals inside, wherein, possible offsetting is provided when there is different measuring-signal mean value.Therefore in the signal processing only consider some, be recorded and be stored in the measuring-signal in control treatment device temporarily, wherein, measuring-signal quantity continuously changes according to FIFO-principle.That is, the measuring-signal of new record supplements described quantity, oldest stored and the measuring-signal of attaching troops to a unit in described quantity be eliminated, therefore achieve the continuous adaptation of new measuring-signal and supplement.
Now, determine two set of signals according to these measuring-signals and determine corresponding signal averaging in set of signals inside, to weaken the width fluctuations that material causes in the longitudinal edges portion section of each consideration.Then determine to offset according to these signal averagings.
The quantity of the measuring-signal comprised by two set of signals is preferably determined like this at this, namely, between set of signals, have the measuring-signal be not considered when signal transacting of some, wherein, the quantity of these measuring-signals is corresponding to the distance of the regulation of cord strip.Therefore, thus by the definition of two set of signals and determining to consider when offsetting two spaced in the conveying direction longitudinal edges portion sections.Select so worthily between, the cord strip portion segment length of measuring-signal definition by not being considered, the arris length that the maximum inclination it being greater than produce when there is arris and offset in stitching section extends.When being generally the minimum splicing angle of 15 °, when arris offsets as 2mm, the pure calculating of this length is 7.46mm, therefore suitable, " irrespective " longitudinal edges portion section is confirmed as being about 10mm or slightly long.
Further preferably, at least one distance measurement device is set, it is connected to upstream or the downstream of measurement mechanism, the commute information of the conveying distance describing cord tape is determined by this distance measurement device, wherein, by this side of control treatment device by corresponding with commute information for the measuring-signal recorded successively.Thus, especially when use with the encoder of the meter wheel be resisted against on belt surface, namely rotary encoder system as distance measurement device time, temporal parsing can be realized.
The quantity of the measuring-signal considered or the selection of measuring-signal to be considered are determined according to the commute information detected worthily.This achieve, select like this in quantity or selection at the measuring-signal determining to consider when offsetting or form set of signals, the velocity variations that may exist also is not affected.Because by correspondingly determining number of signals or selecting signal to be considered to guarantee, there is sufficiently long longitudinal edges portion section to be considered all the time and have longitudinal edges that is enough large, that tilt to extend trend " dropping on " longitudinal edges portion section wherein all the time between these two longitudinal edges portion sections to be considered.

Detailed description of the invention
Fig. 1 shows a kind of possible form of implementation by splicing apparatus 1 of the present invention with the form of schematic diagram, and this splicing apparatus is for docking cord strip portion section to form cord strip 2.The coiled material pull-out that this cord strip material is never shown specifically as rolled material.Be connected with in splicing apparatus 1 upstream cutter sweep 3 and this only schematically illustrate, the reception that is connected to cutter sweep downstream and conveying device 9, receive cut cord tape by this reception and conveying device and be transported to splicing apparatus 1.Shown is only that other parts such as appliance stand, linear guiding device, drive unit etc. are not shown specifically for the reason for the purpose of clear for the central module needed for understanding.
In an example shown, cutter sweep 1 is depicted as the shearing machine with upper slitter 5 and lower cutter 6, and wherein, as shown in by double-head arrow A, upper slitter moves downward to cut.As described in German patent application DE 101 13 397 A1, cord strip to be cut is by being pulled out in this conveying device be not shown specifically and being pulled through cutter sweep 3.Conveying device such as comprises pincers of pulling back, and these pincers of pulling back are caught the band arris above and move linearly, and are pulled through by band between upper slitter 5 and lower cutter 6 thus.If cord strip to be cut is positioned at cutting position, then upper slitter 5 moves down, and the cord strip 7 between cutter is cut.Then be positioned in conveying device 9 to understand that illustrate, cut cord tape 8 in FIG, cut and cord tape 8 to be spliced is transported to splicing apparatus 1 side in this conveying device.The form that is provided with in this region is the alignment means 10 (also will describe in detail this below) of grabbing device, and this alignment means at least can be moved perpendicular to the throughput direction of conveying device 9.This alignment means 10 is for making cord tape 8 lateral transfer (also will describe in detail after this).For this reason, alignment means catches cord tape from the side with the crawl section section of such as tong-like, and this cord tape is transferred towards the direction of splicing line 24 (splicing along this splicing line).As passed through shown in the arrow E in Fig. 2, alignment means 10 is moved in the conveying direction together with cord tape 8, namely synchronizing moving together with cord tape.Be synchronized with the movement in process at this, if if required, cord tape 8 is moved by transverse to throughput direction to revise the offsetting that may detect, as passed through shown in the arrow F in Fig. 2.
By means of conveying device 9, cord tape 8 moves to its stitching position.Another conveying device 11 is connected in conveying device 9, and the cord strip 2 be spliced to be bearing in this another conveying device and to be moved away by this another conveying device.
In stitching position, the arris above of cord tape 8 is arranged in the working region of splicing apparatus 1 or belongs to the splicing upper-part 12 of this splicing apparatus, and this arris can move in the stitching position of below to splice.As Fig. 1 is clearly shown that, the band arris 14 above of cut band portion section 8 be positioned at the cord strip 2 spliced in arris 15 front below.These arris dock in this region mutually.If occupy stitching position, then can start splicing, for this reason, splicing upper-part 12 as correspondingly moved shown in double-head arrow C.Splicing upper-part 12 moves relative to splicing lower component 16, and wherein, arris 14 and 15 to be connected is between these two parts.
Also have two measurement mechanisms 19 by splicing apparatus 1 of the present invention, wherein, illustrate only a measurement mechanism in FIG, another measurement mechanism is positioned in the scope of another longitudinal edges of cord strip 2.Measurement mechanism is for detecting the position of the corresponding longitudinal edges of cord strip 2, can detect possible offsetting in splicing regions based on this Detection Information and to carry out correction interference by controlling alignment means 10 to offsetting, mode is: make cord tape 8 lateral transfer newly to be spliced.Therefore, if longitudinal edges is originally mutually not concordant, alignment can be realized thus, thus make to obtain in the region of stitching section 25 the transverse direction offsetting be in the margin of tolerance.Measurement mechanism 19 communicates with corresponding control treatment device 21, and this control treatment device carries out signal analysis and offset detecting and also controlling alignment means 10 if desired.Control treatment device 21 can be the control device of higher level, and it controls whole operation of splicing apparatus 1 and also controls cutter sweep 3 if desired.
Fig. 2 shows splicing apparatus 1 and arranges to the schematic diagram of its two measurement mechanisms 19a, 19b.On the one hand, figure 2 illustrates that be transferred or just cut cord tape 8, it has two longitudinal edges 22a, 22b and at arris 23a above with at arris 23b below.Cord tape 8 has trapezoidal shape and width b and angle of cut α, and this angle of cut defines the cutting angle of cutter sweep 3 on the one hand, also defines the splicing angle of splicing apparatus 1.
Second cord tape 8 illustrated is positioned near stitching position part.Cord tape has been aligned device 10 and has caught, to align if desired.As by shown in double-head arrow F, grabbing device 10 except also can moving upward in the side perpendicular to throughput direction except being moved upward by the side being parallel to throughput direction shown in arrow E, so that correspondingly lateral transfer cord tape 8.
Suppose that its arris 23a above has alignd and has been in the stitching position spliced with the arris 23b phase below of the cord tape 8 spliced before, should before the cord tape of splicing be the part of the cord strip 2 of splicing.Two arris 23a, 23b separately illustrate for clarity.In order to splice, arris to each other side relatively against.Then, arris by means of splicing upper-part 12 splice in splicing regions along splicing line 24, mode is: splicing upper-part 12 move to below stitching position and two arris be pressed securely onto together by means of appropriate splice elements.This splicing line finally defines splicing angle, this splicing angle is usually between 90 ° (then cutting angle is also α=90 °) to 15 ° (then cutting angle is also α=15 °), and this splicing angle is regulated together with the splicing corresponding swing of upper-part 12 and the corresponding align of cutter sweep 3 by splicing apparatus.
Therefore after splicing, obtain stitching section 25, connect the cord strip portion section 8 be spliced along this stitching section.In the region of this stitching section 25, may occur now that the transverse direction of the cord tape 8 spliced offsets, also will describe in detail referring to Fig. 3 this.In order to detect possible offsetting, be provided with two measurement mechanisms 19a, 19b, these two measurement mechanisms are obviously attached troops to a unit respectively in each longitudinal edges 22a or 22b, and the extension trend for detecting corresponding longitudinal edges.Each measurement mechanism 19a, 19b detect separately corresponding longitudinal edges extend trend and stitching section 25 on corresponding offsetting---vacation if present.Then, possible testing result is by the basis as control alignment means 10, and this should be realized by control treatment device 21.
Fig. 3 schematically illustrates the inner possible different offsetting of cord tape 2.From the stitching section 25 in left side, " the oldest " cord tape 8a and cord tape 8b is then depicted as and offsets (seeing along throughput direction) left, that is, when cord strip width is identical, cord tape 8a offsets relative to cord tape 8b.Namely corresponding longitudinal edges 22a, 22b (see Fig. 2) are also similar to and offset in a same direction.
On the second stitching section 25b that cord tape 8b with 8c is connected, only in the region of longitudinal edges 22b, there is (seeing along throughput direction) offsetting left.Longitudinal edges 22a is evenly transitioned into cord tape 8c from cord tape 8b.That is, cord tape 8c is slightly wider than cord tape 8b.
On the 3rd stitching section 25c connecting cord tape 8c and 8d, contrary with the first stitching section 25a, the both sides provided in the region of two longitudinal edges 22a, 22b to the right offset.Also therefore slightly narrower than cord tape 8c cord tape 8d moves right relative to cord tape 8c.Finally, on the 4th stitching section 25d connecting cord tape 8d and 8e, give and the similar situation on the second stitching section 25b, only on other direction.Cord tape is wider than cord tape again, wherein, mutually concordant at these two tapes in the region of longitudinal edges 22b, and cord tape 8e gives prominence on longitudinal edges 22a.
Therefore occurred different offsetting situations on the whole, these offsettings can be detected by corresponding measurement mechanism 19a, 19b and result through the corresponding correction of alignment means 10 according to offsetting degree.
Fig. 4 there is shown layout and the basic structure of the relative cord strip 2 of measurement mechanism 19a, 19b in the principle of amplifying.Show the alignment means 10 of cord strip 2 and correspondence, as known by DE4309013, this alignment means is such as grabbing device 26.In order to its relative position relative to the longitudinal edges 22b of cord strip can be detected, as shown in by double-head arrow F, the grabbing device 26 such as with one or more sensor can move perpendicular in the both direction of throughput direction, so that cord tape 8 (see Fig. 2) mobile newly to be spliced.This cord tape is not shown specifically in this view.
Therefore that is these two cord tapes transverse shifting relative to each other the cord tapes 8 forming two of cord strip 2 splicings in an example shown have offsetting 27a and 27b in the both sides of stitching section 25, and wherein, these two cord tapes have identical width b.Two measurement mechanism 19a and 19b shown in extra amplification locate so in the diagram, it is positioned at above or below corresponding band arris 22a, 22b, thus band arris are arranged in the measurement category of measurement mechanism 19a, 19b in the conveying direction all the time.
In an example shown, each measurement mechanism 19a, 19b are designed to rectilinear transducer 28a, 28b of optics, it has light source 29a, 29b of arranging, and described light source only schematically illustrates at this and is preferably equally also designed to be parallel to the line source of rectilinear transducer 28a, 28b extension.Rectilinear transducer 28a, 28b comprise the optical pickocff that one or more straight line is arranged abreast, the light that described sensor can be detected the cord strip 2 owing to being radiated at process above or below it by light source 29a, 29b and reflect, and produce like this and send a signal, this signal accurately defines the extension trend of longitudinal edges 22a, 22b.Due to this linear structure, therefore each rectilinear transducer 28a, 28b have a measurement category M (as shown in Figure 4).This measurement category M is such as that 30mm is wide, therefore, known at strip width b, given in the ideal case and when being consistent, although width slightly changes and has offsetting in measurement category inside if desired, corresponding longitudinal edges 22a, 22b still can be detected.Also in order to produce and detect wider cord strip, two measurement mechanisms 19a, 19b can be shifted on a direction perpendicular to throughput direction, as shown in by two double-head arrow G.These two measurement mechanisms can change spacing to each other thus.This can realize pure artificially, but also can automatically realize.For this reason, two measurement mechanisms 19a, 19b preferably move with roller 30a, 30b of the side guiding device being used as cord tape 2 and are coupled.Therefore, if roller 30a, 30b arrange spacing is wider, then two measurement mechanisms 19a, 19b are automatically synchronous with it.Usually in wirecord fabric, such roller is used.In fabric cord, use the guide plate being used for side pilot tape, wherein, also can realize in this case being coupled accordingly.
Two measurement mechanisms 19a, 19b communicate with control treatment device 21, and this control treatment device detects and for determining that all continuous recording measuring-signals are analyzed in offsetting, also will describe in detail this following.
Also be provided with distance measurement device 31, it communicates with control treatment device 21.This distance measurement device 31 to be comprised on a upside being bearing in cord strip 2 and the meter wheel 32 rotated by the cord strip 2 of process, and this meter wheel is a part for encoder.Code device signal is provided to control device 21, by control treatment device 21, this code device signal is corresponding with the measuring-signal of rectilinear transducer 28a, 28b, because of this trip relatively, namely delivered length relatively and and then finally also resolve these signals in time.
By the known measuring principle identified that offsets of Fig. 5-10.Fig. 5 shows two measurement mechanisms 19a, 19b, namely with two rectilinear transducers 28a, 28b of light source 29a, 29b of arranging.In the diagram, these two measurement mechanisms are positioned on a straight line extended perpendicular to throughput direction oppositely, but as shown here, they are arranged with reference to corresponding offsetting 27a and 27b for clarity.See in the conveying direction, two offsetting 27a, 27b finally size H that are spaced from each other due to splicing angle.Therefore, if two measurement mechanisms 19a, 19b arrange opposed to each other, then roughly successively two offsettings 27a, 27b can be detected successively in time.
Measurement mechanism 19a, 19b obtain independent measuring-signal 33a or 33b respectively, and described measuring-signal is by record in succession continuously.Measuring-signal record is timing---such as according to the time beat of regulation or such as by the code device signal of distance measurement device 31, to make measuring-signal record adapt to reality-transporting velocity by this way.
In Figure 5, and in Fig. 6-10 below, single measuring-signal 33a, 33b is shown side by side along corresponding longitudinal edges 22a, 22b.This is due to the appearance of diagram reason.Certainly, corresponding measurement mechanism 19a, 19b do not move, but cord strip 2 moves across.At this, measuring-signal 33a, 33b are recorded in identical measurement mechanism position all the time, but are on different longitudinal edges positions.That is, therefore continuous recording measuring-signal 33a, 33b can be corresponded to the longitudinal edges position of regulation.
Measuring-signal 33a, 33b are supplied to control treatment device 21 continuously.This control treatment device stores the measuring-signal of the defined amount of each longitudinal edges 22a, 22b, processed in the framework that described measuring-signal is formed at mean value.Signal storage realizes according to FIFO-principle.That is, always consider the measuring-signal number specified, but due to continuous print record, measuring-signal to be considered changes continuously.If the new measuring-signal of current record is provided, then delete the oldest measuring-signal to be considered in processes from storage device.Therefore always add new measuring-signal, and shift out the oldest corresponding measuring-signal.By this way, the number of that be stored, to be considered measuring-signal remains constant, but continuous updating.
Now, control treatment device 21 forms two set of signals by the measuring-signal of these defined amounts.One of them set of signals comprises the oldest measuring-signal of given number, and another set of signals obtains the up-to-date measuring-signal of given number.The set of signals that one comprises the measuring-signal be not considered is there is between two set of signals.Because as mentioned above, each measuring-signal can be corresponding with the longitudinal edges position of regulation, therefore specific longitudinal edges portion section can be detected by each measuring-signal collection, namely depict " older " longitudinal edges portion section by the set of signals comprising the oldest measuring-signal on the one hand, and depict " newer " longitudinal edges data by the set of signals with up-to-date measuring-signal on the other hand.Have a region with the arris length of regulation between which, this region is described by " centre " set of signals, should " centre " set of signals not be considered when analyzing.Such number selecting the length of middle longitudinal edges portion section and then selection to be arranged in the measuring-signal at this interval, makes it be greater than the offsetting arris length of the maximum instability drawn by the average offsetting of splicing angle and such as 2mm all the time.Control treatment device 21 to be formed by two data sets (representing with S1 and S2 in Figure 5) corresponding signal averaging with compensate come from material possible slight arris fluctuation after, so a kind of situation is created through out-of-date in offsetting, wherein, control device only by the first mean value forming set of signals S1 for " older ", the value of cord tape 8 of splicing before, and is only formed the mean value of set of signals S2 by the measuring-signal for cord strip 8 that is newer, that finally splice.That is, the average bits of set of signals S1 in stitching section 25 before and therefore before offsetting 27, and the average bits of set of signals S2 is after stitching section 25 and therefore after offsetting 27.If draw the difference of overrate thus, then draw corresponding offsetting.Corresponding information is controlled treating apparatus 21 and is moved to make cord tape 8 newly to be spliced for controlling alignment means 10.
Fig. 6-10 shows the analytic process for the moment offsetted through measurement mechanism 19a, 19b.Schematically illustrate to illustrative longitudinal edges 22a and offsetting 27a there.Also show measuring-signal 33a, it passes through the measurement mechanism 19a record be not shown specifically at this.For clarity, each set of signals S1 and S2 of being formed in control treatment device 21 is shown.They define corresponding longitudinal edges portion section X1 and X3.Have longitudinal edges portion section X2 between which, in this longitudinal edges portion section X2, certainly same record measuring-signal 33a, that is, therefore also can gather corresponding measuring-signal at this place.But, because this measuring-signal is not considered, so it is not shown specifically in the drawings when analyzing.That is, control treatment device 21 by be supplied to it and the entirety of the measuring-signal mainly will considered forms corresponding set of signals.Exemplarily can suppose, the total number of the measuring-signal 33a be considered is 100.Now, in this number, form two set of signals S1 and S2, it such as comprises 40 measuring-signals respectively.All the other 20 measuring-signals, between them, are not considered as the 3rd set of signals and finally correspond to longitudinal edges distance X2.Each measuring-signal newly added is assigned to set of signals S2.Meanwhile, the oldest measuring-signal of set of signals S2 is assigned to " centre " set of signals comprising the measuring-signal be not considered, that is is not considered.Then the measuring-signal the oldest again comprising the set of signals of that be not considered, the oldest measuring-signal is assigned to set of signals S1.The measuring-signal the oldest again of set of signals S1 is deleted, and then it does not participate in analysis as measuring-signal the oldest generally.
In current situations, corresponding mean value is formed by set of signals S1 and S2 now.Exemplarily can suppose, measuring-signal can change between 1 to 0, and wherein, the signal value of longitudinal edges corresponded to 1 before offsetting, and the signal value of longitudinal edges corresponds to 0 after offsetting.
Corresponding mean value has been shown in chart below
, and the corresponding difference DELTA between these two mean values.Because obviously all measuring-signals were recorded before offsetting 27a, and therefore the signal value of all measuring-signals is 1, and drawn two mean values " 1 ", their difference is 0.So there is no offsetting be detected.
According to Fig. 7, band continues motion slightly, and synchronous signal position and the distribution in corresponding measuring-signal collection S1 and S2 inside change.Obviously, set of signals S1 only comprises again the measuring-signal with signal value 1, and these measuring-signals were still recorded before offsetting 27a.But measuring-signal collection S2 had recorded before being both included in offsetting 27a now, signal value is the measuring-signal of 1, also comprise directly record in offsetting 27a and partly also slightly at the measuring-signal of offsetting 27a opposite side record.That is, therefore offsetting 27a has run through measurement mechanism 19a, but in signal analysis, still have a considerable amount of " older " measuring-signal detected before offsetting to be considered.
Exemplarily can suppose, the mean value of set of signals S2 in this case 0.5.Therefore average value difference Δ=0.5 is drawn on the whole.This shows, obviously creates discontinuous in the extension trend of longitudinal edges.Whether is offset and whether therefore detect maximum offsetting width or the unknown this its, this only just manifests in further signal analysis.
Now in next the width chart press Fig. 8, the signal univocality ground of two set of signals S1 and S2 and only corresponding to the corresponding longitudinal edges portion section before or after the 27a of stitching section.All measuring-signal 33a of set of signals S1 are before the 27a of stitching section, and signal value is 1, and corresponding mean value is 1, and all measuring-signal 33a of set of signals S2 be positioned at stitching section 27a after and therefore all there is signal value 0, therefore signal averaging is 0.Show that average value difference is 1 thus.That is, in continuous print signal analysis, difference rises to present 1 from 0 through median 0.5.
As Fig. 8 clearly illustrates, determine the size of arris length X2 like this, therefore namely specify the number of the measuring-signal be not considered like this, the arris of the maximum instability that obtained distance or length are greater than in offsetting 27a (therefore longitudinal edges tilts to extend herein) extends trend.This guarantees, provides such situation at least one times, that is, set of signals S1 only comprises the measuring-signal corresponding to " old " cord tape, and measuring-signal collection S2 only comprises the measuring-signal corresponding to " new " cord tape.Therefore draw maximum average value difference thus, it indicates clearly and offsets and also illustrate its size.
Fig. 9 shows further signal analysis.Due to constantly newly increase, the measuring-signal that causes the measuring-signal in individual signals collection S1 and S2 to be moved, present set of signals S1 is approximate is " mixing collection ", it obviously comprises the measuring-signal that signal value is 1, also comprise and be in offsetting and the therefore signal value measuring-signal that is less than 1, also comprise signal value and be 0 and therefore corresponding with the arris region being positioned at stitching section 27 opposite side measuring-signal.Exemplarily can suppose again at this, the signal averaging drawn here is 0.5.
In contrast, all signal values of set of signals S2 are from the longitudinal edges portion segment record (as described see Fig. 8) being positioned at offsetting 27a opposite side, and its whole signal value is 0, therefore show that mean value is 0.Therefore again show that average value difference is 0.5.That is, difference again declines from Fig. 8.
Figure 10 illustrate only such situation, wherein not only offsetting 27a process, and does not technically also enter analysis from the measuring-signal in offsetting region again at measuring-signal.So obviously can find out, the signal of two set of signals S1 and S2 is all by the tape recording of " new " cord bar, and therefore the two be all positioned at the opposite side of offsetting.All measuring-signals have signal value 0 ideally, and the mean value drawn is 0 and difference is also 0.
Example above shows, offsetting can be detected clearly based on mean value formation and corresponding poor formation, because obviously difference rises to maximum from minimum and then again decline.Offset when extending on other direction and can realize equally offsetting detecting.That is, with in which direction occur offsetting independently, be under any circumstance with arbitrarily side can detect offsetting degree.
Illustratively measurement signal value is given as 0 and 1 at this.Can certainly correspond to concrete position or distance value by each measuring-signal, that is, can accurately detect eventually through formation difference, offsetting is 0.5mm or 1mm, 2mm etc.Have much according to the offsetting of reality, correspondingly control alignment means 10, so that the cord tape 8 that correspondingly migration is next to be spliced on one or the other direction and correction offset, it is positioned within tolerance again in both sides.As mentioned above, the beat of measuring-signal record is such as by the distance measurement device 31 namely next timing of encoder.Such as every 0.2mm carries out measuring-signal record, therefore every millimeter of arris length records 5 measured values.This achieve longitudinal edges extend the meticulous of trend and detect accurately, corresponding set of signals can be formed by enough signal numbers.
Measurement mechanism 19a, 19b are connected to splicing upper-part 12 downstream as stated.But measurement mechanism 19a, 19b be comparatively close splicing upper-part 12 preferably, can detect the stitching section 25 of up-to-date generation as far as possible early and to control possible offsetting.More early carry out offsetting to control, then more early can carry out correction interference by the grabbing device of alignment means 10 namely tong-like.At this, grabbing device 10 is moved upward, even if this achieve high-precision adjustment and therefore also achieve the high-precision correction to less offsetting by the positioning drive unit of appropriate servomotor or stepper motor, namely electricity on the direction of arrow E and the especially side of arrow F.
