Description

Device with ultrasonic wave cutting and/or welding of belt
The present invention relates to a kind of device with ultrasonic wave cutting and/or welding of belt, the driving link of this device constitutes (referring to DE-3925788Al) by a vibration transmitter and the tip oscillator that vibration is strengthened that is divided into several sections.
In order to produce belt, label band for example, people weave out earlier a broad fabrics band, process the desired belt patterns of many groups in the adjacent zone of this band, and the boundary between these zones is cut the broad fabrics band open then.What adopted for this reason is the wire of heating, produces a fusing cutting mouth by wire in the fabric band, simultaneously the gauze broken end that is cut off is welded together mutually.But the melt-edge of Xing Chenging is very hard like this, and brings the problem (seeing DE-3937947-A1) that must take addition thereto to solve.Quality problems when cutting in order to improve, people have begun to adopt ultrasonic wave patterning method (EP-0534300-A1) in weaving.
Known above-mentioned ultrasonic cutting device need account for a lot of places, and the length of their vibration transmitter and tip oscillator all must be accurately tuning with the alternating voltage frequency of the generator that drives these parts.This also will describe in detail in conjunction with Fig. 2 afterwards.The resonance curve that in well known device, produces be very sharp-pointed and frequency range narrow.The wave length of sound that the axial length of this resonance curve requirement vibration transmitter and the piezoelectric element of vibration transmitter produce is accurately tuning.But even for the device of same structure, it is very different each other that the error of Chan Shenging will make the position of each resonance curve in the mill, so that for making the device operation must adopt alone generator.The alternating voltage of the generator that these are different must be regulated corresponding to each resonant frequency of the device that matches.Because the size of structure member is big and quantity is many, these well known devices are all quite expensive, and its efficient is lower in addition.
The objective of the invention is to develop a kind of cheap and good-quality device with ultrasonic wave cutting and/or welding of belt, it is characterized in that compact conformation, work is economical reliable.This realizes that by the described measure of claim 1 characteristic these measures have following Special Significance.
In device of the present invention, vibration transmitter only used piezoelectric element and dorsad reverse section of band and oppositely section directly be pressed together with the tip oscillator, shortened the axial length that installs thus.Formed a kind of new construction unit thus, this construction unit is combined by reverse section, piezoelectric element and tip oscillator, it is abbreviated as after therefore: " sub-assembly ".And the present invention has also abandoned so far in the prior art usually size Selection that vibration transmitter and tip oscillator these parts are adopted, its reverse section used axial length is 1/8 of wave length of sound to the maximum, and the axial overall length maximum of its sub-assembly has only 3/4 of wave length of sound.Because device of the present invention shortened axial length greatly, so its cross section also can dwindle, and so not only saved the locus, and saved many materials, and this is of crucial importance when material therefor is very expensive.Practice shows, unlike the prior art be, in device of the present invention, produced smooth resonance curve, this resonance curve no longer claimed structure length with given wave length of sound accurately tuning.This point also will describe in detail.The present invention can also be connected to the sub-assembly of a plurality of separate work on the public generator in parallel.Therefore can provide alternating voltage to all cutting assemblies that are arranged on the loom by a public generator.
Other measure of the present invention and advantage are provided by following description and accompanying drawing.Be the prior art except one in the accompanying drawing, show some embodiments of the present invention.

Fig. 8 is that the another kind of combination device of the present invention in a blanking instrument used.
Make band 10 with common textile technology by 12 braidings of warp thread 11 and one or more strands of weft yarn on loom shown in Figure 1, can inweave pattern 13 arbitrarily thereon simultaneously, this is especially significant for will weave label on this loom the time.In this case, as broad fabrics, on many zones arranged side by side mutually of band 10, produce label design 13.Then band is transferred to many cutter sweeps 20, cut out longitudinal cut 14 in desirable place, they make band 10 cut into single band 15.Corresponding to weaving process, the band 15 that cut out along the direction tractive of the arrow 77 that moves in 11,12 o'clock at braiding warp thread and weft yarn is divided into desired section according to the length of pattern 13 with band then and constitutes the label that can be fixed on clothing or the similar articles.
What this case related to is a kind of cutter sweep with ultrasonic wave work, this device has the generator that can see 50 from Fig. 1, this generator 50 produces for example high-frequency ac voltage of 20～30 KHzs by common alternating current, and this high-frequency ac voltage is defeated by a driving link that also will describe in detail 20 of device of the present invention through electric wire 31.This driving link 20 for example is positioned on the observation side 16 of band, and it is furnished with a Passive part 30 on relative band dorsal surface 17, and this Passive part is hereinafter to be referred as " anvil ".The band 10 that cuts is between driving link 20 and anvil 30.Alternating voltage (also will be described in detail in detail later on) in driving link 20 to be transformed into the ultrasonic wave of same frequency and to strengthen the back at amplitude and be delivered on the band 10 as vibrational energy.Driving link 20 resembles and acts on the tup, sends the mechanical type hammering of 20 to 30000 pulses of per second with itself and the contacted end 28 of band.The friction that produces in this hammering campaign produces heat effect to band, can be used for the separation or the welding of band 10.When hammer tip 28 is that point the time just forms a kind of ultrasonic wave cutting, and just form a kind of welding when being flat when hammer tip 28.Rim along cut surface is melted, and avoids fabric to form diffusing limit at 14 places, cutting mouth position thus.Band fusing is can also to apply mechanical destruction at cutting part 14 places of band except making, and therefore also can use the material that can not melt in band 10, cotton yarn for example, and this material can be with the tip separation.
The following outward appearance that can from Fig. 2, find out more in detail of known driving link 20 ' have.The vibration signal of telecommunication that comes from the generator referred to a vibration transmitter 24 ' be transformed into mechanical oscillation.Vibration transmitter 24 ' be divided into three section 21 vertically ', 22 ', 23 ', they are columniform, each other by an axial bolt 18 ' fixedly connected.The signal of telecommunication arrive two piezoelectric ceramics 25 ', the mutual vibrate in opposite phase of this two piezoelectric ceramics 25 ' under working condition be and constitute vibration transmitter 24 ' first axial direction part 21 ', be designated hereinafter simply as " piezoelectric element ".Two other axial direction part 22 of this piezoelectric element 21 ' be connected ', 23 ' between, and this material of two sections is different.The acoustic vibration of piezoelectric element 21 ' generation with very different modes be sent to other two section 22 of being positioned at piezoelectric element 21 ' two ends ' and 23 ' on.Be delivered to the axial direction part 22 that is positioned at the outside ' on acoustic energy should be low as much as possible, so this section make with steel, below it abbreviated as " oppositely section ".On the contrary, vibration transmitter 24 ' first axial direction part 23 that is positioned at piezoelectric element 21 ' other end ' then answer dampen out may be high the acoustic energy that is produced and with its pass to the following tip oscillator 26 that also will describe in detail ', energy obtains using herein.Therefore afterwards with axial direction part 23 ' abbreviate as vibration transmitter 24 ' " acting section ", this acting section 23 ' make by aluminium.
Tip oscillator 26 ' through threaded 19 ' only and aforesaid acting section 23 ' link to each other, and be that titanium material by costliness constitutes.The task of tip oscillator be increase from vibration transmitter 24 ' hyperacoustic amplitude, it have a taper by the section of contracting 27 '.Most advanced and sophisticated 28 ' contact band and have sharp cutting edge face 29 ', be used to cut out the otch that the front has been mentioned.Tip oscillator 26 ' length 36 ' approximately be acting section 23 ' length 33 ' twice because the drawing position is limited, in Fig. 2, only show its two ends.
Vibration transmitter 24 ' each section must have among Fig. 2 the appreciable axial length 32 accurately tuning with used ultrasonic vibration ', 33 ', 36 ', so that most advanced and sophisticated 28 ' can produce enough acoustic energy.Ultrasonic wave in driving link 20 ' middle generation causes so-called " standing wave ", and this " standing wave " has so-called " vibration antinode " and " node of oscillations " with null with big amplitude.The wavelength of standing wave is relevant with ultrasonic frequency on the one hand, and is relevant with the medium that forms this standing wave on the other hand.Though this standing wave is a longitudinal wave, in order to show better, on the right-hand part drawing of Fig. 2 with formed standing wave 37 ' illustrate with the form of oscillation crosswise.' energy of locating most advanced and sophisticated 28 in order to make obtains optimum utilization, and prior art requires the ultrasonic frequency that produced accurately to mate with the axial length of each section as follows.
Should vibration transmitter 24 ' two piezoelectric ceramics 25 ' between mid point produce standing wave 37 ' node of oscillations 35 ', the outside reverse section 22 ' have axial length 32 ', under the situation of considering the velocity of sound in this section material, this length 32 ' should accurately equal half wave length of sound, be λ/2, this moment reverse section 22 ' upper end form a vibration antinode 34 '.Under the situation of the material of considering acting section 23 ' adopted, the axial length 33 of this section ' also must equal half wave length of sound λ/2 so that with the tip oscillator 26 that joins ' transition position form a vibration antinode 34 '.Vibration transmitter 24 shown in Figure 2 ' whole axial length also be λ.In other known device, the axial length of these parts is at least λ/2, or its integral multiple.Correspondingly, tip oscillator 26 ' axial length 36 ' also be like this, as the standing wave 37 that shortened among Fig. 2 ' view, this tip oscillator 26 ' length must equal wave length of sound λ or its integral multiple equally.To consider this moment taper pursue the section of contracting 27 ', only in this way the vibration antinode 34 that could work in most advanced and sophisticated 28 ' formation '.Node of oscillations 35 ' be positioned at axial direction part 36 ' within.As shown in the figure, driving link 20 commonly known in the art ' length overall be 38 ', it is the twice of the wave length of sound in related different materials at least, i.e. 2 λ.Corresponding to this big length 38 ', known driving link 20 ' each section have big diameter 39 '.
As previously mentioned, the driving link 20 of known cutter sweep ' have sharp-pointed resonance curve 51 ', as shown in Figure 3.In Fig. 3, the vibrational energy E that transmit draws according to effective frequency of sound wave f.Known resonance curve is limited in effective resonant frequency f.A very narrow scope in, the audio frequency that is produced has skew will cause off resonance slightly, make the tip 28 of contact ' can not form stable standing wave 37 ' vibration antinode 34 '.Therefore require described axial length 32 ', 33 ', 36 ' accurately tuning with the effective ultrasonic wave frequency.This tuningly generally carry out through alternate voltage-changing generator, this generator must be done the electric oscillation frequency of its output to adjust accordingly again.
Therefore, two known driving links 20 that structure type is identical so far ' must drive by independent alternate voltage-changing generator respectively.The error that work in-process produces made axial length 32 ', 33 ', 36 ' different, thus must be to resonant frequency f oCarry out different adjustment mutually.Therefore, if resemble Fig. 1 in the time of will wide-format webs 10 being cut into many fabric support member bands 15 with several ultrasonic cutting devices 20, above-mentioned situation just mean need be very high installation cost and space expenses.In addition, known driving link 20 ' in, piezoelectric element 21 ' must pulsed ground that is have the ground work of static phase place.
With respect to prior art, the present invention has had great improvement, and this can be illustrated by driving link of the present invention 20 shown in Figure 4.The label of parts is identical with the label of the driving link shown in Figure 2 20 ' used of expression prior art, but has removed apostrophe ('), to show difference.Its difference and special character discussed herein is just much of that, and then hereto description is still effective for remainder.
Characteristics of driving link 20 of the present invention are that tip oscillator 26 directly is contained on the piezoelectric element 21, and this piezoelectric element also is made of two piezoelectric ceramics 25 herein, and supply with alternating voltage by the electric wire 31 of generator 50 shown in Figure 1 through also seeing in Fig. 4.Except that tip oscillator 26 and piezoelectric element 21, only be provided with an oppositely section 22.These parts 26,21,22 directly interfix with an axial bolt 48 and compress.The axle of screw 48 passes the axial hole in two potsherds 25 of reverse section 22 and piezoelectric element 21.For the connection of electric wire 31, axle insulate with flexible pipe 47 on regional area.The end of screw 48 directly enters in the screwed hole 46 of the blind hole structure in the tip oscillator 26.Form a new driving link that combines 20 by these parts in the present invention, beginning had been said as this paper, later on it was abbreviated as " sub-assembly ".In sub-assembly 20 of the present invention, saved with driving link 20 of the prior art ' acting section 23 ' corresponding parts, from two ratios of Fig. 2 and Fig. 4 approximately identical view just compare and can find out, except save parts 23 ', axial length of the present invention is also much shorter.Therefore the diameter 39 of these parts also can correspondingly reduce, and parts 20 used Master Costs of the present invention will be significantly less than parts 20 of the prior art ' used Master Cost.
Because oppositely 22 the longest needs of section are 1/8 of effective wave length of sound λ, therefore can shorten reverse section 22 axial length 32.In the embodiment shown in fig. 4, oppositely section 22 is made by the high-quality steel, and 32 of its axial lengths are 1/16 of effective wave length of sound.Surprisingly, this axial length 32 can change to a great extent, can not make the good quality of cutting or welding become very poor simultaneously again.The axial length 36 that belongs to the tip oscillator 26 in this sub-assembly also is like this, and practice shows, its length 36 can effective wave length of sound 7/16 to 10/16 between scope in change arbitrarily.This point also will contrast Fig. 3 later on and describe in detail.The material that is used for tip oscillator 26 in this example is a kind of what is called " duralumin ", that is is a kind of alloy of being made up of aluminium, magnesium and silicon, begins to measure from piezoelectric element 21 central authorities, and the axial length 36 of tip oscillator 26 is about 3/8 λ in this example.The length overall 38 of the sub-assembly among Fig. 4 20 is about λ/2 like this, promptly is 1/4 of known driving link 20 ' length overall shown in Figure 2.Similar with Fig. 2, in Fig. 4, also show the standing wave 37 that is used for sub-assembly 20 herein that institute's side gets.The amplitude of the mechanical oscillation of expressing on abscissa that produced illustrates with logarithm value.As shown in the figure, form the very big vibration antinode 34 of amplitude at most advanced and sophisticated 28 places, and big centre formation node of oscillations 35 about piezoelectric element 21.This favourable shape of standing wave is that the following further structure by this sub-assembly obtains.
The tip oscillator 26 of sub-assembly 20 of the present invention has a special latter end part 40 that is made of different materials, shown in Figure 4 and 5.The tip 28 that also is provided with cutting edge face 29 under this routine situation is made of an end part 41, and the used light metal alloy of the epimere of these end part 41 material therefors and tip oscillator 26 43 is different, and it is the steel of hardness greater than HRC60.Epimere 43 extends by the part 24 that contracts with a taper and finally is connected together with columniform end part 41.The latter end 40 of tip oscillator 26 is coupled together by a threaded 49 and epimere 43, and the two ends of this threaded 49 all screw in the screwed hole 59 of blind hole structure, and this can clearly see from Fig. 5.For the adverse influence that compensation vibration caused, between end part 41 and epimere 43, be provided with a plug-in unit 42 that preferably constitutes by pure titanium, its task is the loss that reduces when the transmitting vibrations energy.The plug-in unit 42 of this titanium ring structure is axially passed and makes the vibration in threaded 49 zones to be decayed by threaded 49.
Making threaded 49 front ends 44 and screwed hole 59 end faces 54 be in that good face contacts is highly significant, as shown in Figure 5.For this reason, threaded 49 has a radially step 45 with tapered front end 44.The end face 54 of screwed hole 59 all has a corresponding complementary back taper in the end of tip oscillator 26 part 41 and epimere 43.Make by this contact and in the zone of threaded 49, also can transmit axial force well.
As shown in Figure 3, sub-assembly 20 of the present invention have one with the diverse favourable resonance curve 51 of aforementioned prior art, it is at resonant frequency f oScope in have a wide quite flat maximum.In fact resonance curve 51 can be positioned at resonant frequency f at a sizable frequency range △ f(△ f oThe gauge frequency f of both sides 1And f 2) in identical energy is discharged at most advanced and sophisticated 28 places., this means to have changed conclusive axial length 32 and 36, and don't the superperformance of sub-assembly 20 is suffered damage in the face of can seeing in the explanation that Fig. 4 did as in the past.That is it and the length overall 38 that do not require said sub-assembly 20 accurately equal wave length of sound half, i.e. λ/2, but deviation can be arranged.The very big advantage that it had is (in Fig. 1 appreciable), and under any circumstance the sub-assembly 20 of all same types that are provided with in loom can both link to each other with same alternate voltage-changing generator 50 no problemly now.This simplifies structure greatly and brings following advantage.
