Description
POSTOPEK ZA IZDELAVO ZADRGI NEGA TRAKUPROCEDURE FOR MANUFACTURING TAPE CARE
PODROČJE TEHNIKE IZUMAFIELD OF THE INVENTION
Izum sodi v področje življenjskih potrebščin, podrobneje v področje galanterije, specifično pa v področje izdelave zadrg.The invention belongs to the field of consumer goods, more specifically to the field of haberdashery, and more specifically to the field of manufacturing zippers.
TEHNIČNI PROBLEMTECHNICAL PROBLEM
Tehnični problem je, kako izdelati zelo kvalitetno zadrgo in to glede na trdnost ob delovanju prečnih sil, kot tudi na odpornost proti lomu ob zvijanju.The technical problem is how to make a high-quality zipper, given the strength of the transverse forces, as well as the resistance to fracture when twisted.
STANJE TEHNIKEBACKGROUND OF THE INVENTION
Trak z zadrgo je sestavljen iz nosilnega traku in niza členkov zadrge. Možno je naprimer istočasno izdelovati dva trakova, ki sta v funkciji zadrge nameščena eden nasproti drugemu in sicer z ob tkanju zgruženima nizoma členkov zadrge. Trn, ki oblikuje členek zadrge je v tem primeru dolg, igličast sestavni del, ki je prosto uležajen (DE 25 40 272). Vendar je možno delati tudi s trnom, ki je v primerjavi s predhodnim sorazmerno kratek in oblikovan kot kavelj ter nameščen na gibljivi ročici (EP 0 124The zipper strap consists of a carrier strap and a set of zip ties. For example, it is possible to simultaneously produce two strips that are positioned opposite one another in the function of a zipper, by stringing together a series of zipper joints. The mandrel forming the zipper joint is in this case a long, needle-shaped, freestanding component (DE 25 40 272). However, it is also possible to work with a mandrel that is relatively short and shaped like a hook and is mounted on a movable lever compared to the previous one (EP 0 124
129). Na ta način se v splošnem izdeluje samo posamezen trak z zadrgo. Drug trak za zadrgo, ki je namenjen zapiranju z zadrgo, se dodaja na drugem mestu in ob drugem času. členki zadrge, oblikovani na trnu, se ob tkanju nepretrgoma snemajo s trna, oziroma se odrivajo.129). In this way, only a single zipper tape is generally made. Another zipper strap, which is intended to be fastened with a zipper, is added at a different location and at a different time. the clasps of the hook-shaped zipper shall be continuously removed from the mandrel or worn off when weaving.
V okviru poznanih mer (DE 25 40 272, EP 0 124 129) je možno dobiti dovolj točno definirane členke zadrge in nize členkov zadrge glede mere, vključno z mero naklona. Glede oblikovanja spojnih glav in spojnih ušesc, je vsekakor treba upoštevati moteče tolerance. Takoj ni mogoče dobiti dovolj dobro oblikovane spojne glave. Omenjene tolerance lahko škodljivo vplivajo na trdnost ob delovanju prečnih sil in na odpornost proti lomu ob zvijanju in prepogibanju. Da se vsaj pri spojnih glavah zagotovijo ožje tolerance, je v okviru poznanih ukrepov običajno, da se spojne glave predhodno vtisnejo na vstopno monovlakno iz plastične mase. To škodljivo vpliva na tkanje in na hitrost tkanja.Within known dimensions (DE 25 40 272, EP 0 124 129), sufficiently well-defined zipper joints and sets of zipper joints can be obtained, including the inclination rate. With regard to the design of the coupling heads and the couplings, interfering tolerances should definitely be taken into account. A sufficiently well-designed coupling head cannot be obtained immediately. These tolerances can adversely affect the tensile strength of the transverse forces and the resistance to fracture when twisted and folded. In order to provide a narrower tolerance for at least the coupling heads, it is customary within the known measures to pre-press the coupling heads onto the inlet monofilament of plastic. This has a detrimental effect on the weaving and the speed of the weaving.
OPIS REŠITVE TEHNIČNEGA PROBLEMA S PRIMERI IZVEDBE IN KRATKIMDESCRIPTION OF THE TECHNICAL PROBLEM SOLUTION WITH EXAMPLES AND SHORT
OPISOM PRILOŽENIH RISBDESCRIPTION OF THE ATTACHED DRAWINGS
Izum se nanaša na postopek izdelave zadrginega traku s tkanjem na avtomatih za tkanje z iglo, pri čemer se niti osnove nosilnega traku in povezovalne niti vodijo tako, da nastaja tkanina. Igle za tkanje uvajajo niti votka nosilnega traku, kot tudi monovlakno iz plastične mase, pri čemer igla za tkanje, ki se stalno giblje iz zunanjega v notranji položaj, ovija monovlakno iz plastične mase okoli trna. Iz plastičnega monovlakna se stalno oblikuje niz členkov zadrge, členki zadrge so vedno sestavljeni iz spojnih glav in priključenih krakov členkov zadrge. Ti kraki oblikujejo spojna ušesca in so s spojnimi deli združeni, pri čemer je istočasno niz členkov zadrge s povezovalnimi nitmi kot tudi z nitmi votka nosilnega traku povezan tako, da oblikuje nosilni trak, pri čemer se vlečna napetost prihajajočega plastičnega monovlakna uravnava s pogonskimi dovodnimi valji za pritegovanje. Na vlečno napetost vpliva tudi gibanje igle za tkanje in to tako, da je maksimalna vlečna napetost v izhodnem položaju igle za tkanje, pri katerem se plastično monovlakno vleče proti trnu.The invention relates to a method of manufacturing a zipper web by weaving on needle-weaving machines, wherein neither the base of the carrier tape nor the connecting thread is guided to form a fabric. Weaving needles introduce strands of weft carrier tape as well as monofilament of plastic, the weaving needle moving continuously from the outer to the inner position wrapping the monofilament of plastic around the mandrel. A series of zipper knuckles is constantly formed from plastic monofilament, zipper knuckles always consist of connecting heads and attached zipper knuckles. These arms form the connecting ears and are joined to the connecting parts, while at the same time a series of fasteners of the fasteners with connecting threads as well as the weft threads of the carrier belt are connected to form the carrier belt, whereby the pulling tension of the incoming plastic monofilament is controlled by the drive feed rollers. to attract. The pulling tension is also affected by the movement of the weaving needle, such that the maximum pulling tension is in the exit position of the weaving needle, in which the plastic monofilament is pulled against the mandrel.
Naloga izuma je iznajti tak postopek, kjer ni potrebno predhodno vtisniti spojnih glav na monovlakno iz plastične mase, pri čemer nastajajo zelo točni členki zadrge ter spojne glave, kar zagotavlja visoko kvaliteto, še posebej glede na trdnost ob delovanju prečnih sil, odpornost proti lomu ob zvijanju in prepogiban ju, poleg tega pa je mogoča izdelava zadrg ob veliki hitrosti tkanja.It is an object of the invention to invent such a process where it is not necessary to pre-press the coupling heads on the monofilament of plastics, producing very accurate fasteners of the fasteners and coupling heads, which ensures high quality, especially with respect to the transverse forces, fracture resistance when breaking they are twisted and folded, and zippers can be made at high speed weaving.
Za rešitev te naloge izum priporoča, da se dela s prevojnim trnom, ki ima skoraj pravokoten prečni presek ter debelino, ki je za 10 do 20 % manjša od premera plastičnega monovlakna in ima na strani spojnih glav vzdolžno zaokrožitev ter širino, ki je večja od debeline za faktor med 1,75 in 3, prednostno za 2, da je vlečna napetost v prihajajočem plastičnem monovlaknu na mestu tkanja: pri plastičnem monovlaknu premera okoli 0,5mm od 300 do 500 gramov, pri plastičnem monovlaknu premera okoli 0,6mm od 500 do 800 gramov ter pri plastičnem monovlaknu premera okoli 0,75mm od 800 do 1200 gramov in, da je zunanji položaj igle za tkanje tako prirejen, da se v tem položaju igle za tkanje vlečna napetost v plastičnem monovlaknu poveča za faktor od 1,5 do 3, pri čemer plastično monovlakno na trnu podpira ta napetost. Tako imenovano ovijanje z namenom, da se oblikuje spojna glava na nizih členkov zadrge iz plastičnega monovlakna, je samo po sebi že poznano. Pri tem nastale spojne glave v smislu oblikovanja niso zelo definirane. V nasprotju s tem izhaja izum iz spoznanja, da je pri postopku tkanja možno poboljšano ovijanje in to na eni strani z uporabo posebnega prevojnega trna ter na drugi strani z zagotavljanjem posebnih vlečnih napetosti ob ovijanju. Prevojni trn ima vzdolžno prevojno zaokrožitev, ki pripomore k ovijanju, ter poleg tega posebno vnaprej določeno širino. Ta širina daje prevojnemu trnu površinski vztrajnostni moment, ki pomaga napetosti ovijanja, da se ne poškoduje trn. Širina prevojnega trna definira istočasno tudi spojno ušesce. Tako nastajajo spojna ušesca, katerim so dodane spojne glave, ki se v spojnih ušescih zaradi oblike dovolj trdno držijo, tako da je dosežena potrebna trdnost glede na delovanje prečnih sil in trdnost glede na lom ob prepogibanju, obenem pa je ušesce zadosti veliko, da zadrga, izdelana iz zadrginega traku, v celoti izkazuje zadostno, celo izredno fleksibilnost. Napetost ovijanja vodi k veliki prevojni hitrosti, kar ima pozitivni vpliv na oblikovanje. Skladno z izumon se spojne glave, ki so izdelane z napetostnim ovijanjem, ob toplotnem fiksiranju stabilizirajo brez motečih sprememb oblike. K optimiranju doprinese, če se gibanje igle za tkanje navznoter tako priredi, da se v notranjem položaju igle za tkanje vlečna napetost poveča za faktor med 1,2 in 2,5, pri čemer plastično monovlakno podpira predhodno formiran spojni del, ki ga obdajajo niti osnove in/ali votka. Samo po sebi je umevno, da so niti votka dovolj močne, oziroma, da je število osnovnih niti dovolj veliko.In order to accomplish this task, the invention proposes to work with a twisting mandrel having a nearly rectangular cross-section and a thickness that is 10 to 20% smaller than the diameter of the plastic monofilament and having a longitudinal rounding on the side of the connecting heads and a width greater than thickness by a factor of 1.75 to 3, preferably 2, that the tensile stress in the incoming plastic monofilament is at the weaving site: for plastic monofilaments of about 0.5mm in diameter from 300 to 500 grams, for plastic monofilaments of about 0.6mm in diameter up to 800 grams, and for plastic monofilaments of about 0.75mm in diameter from 800 to 1200 grams, and that the outer position of the weaving needle is adjusted so that in this position of the weaving needle the tension in the plastic monofilament is increased by a factor of 1.5 to 3, wherein the plastic monofilament on the mandrel supports this tension. The so-called wrapping in order to form a coupling head on a set of plastic monofilament zip links is already known in itself. The resulting coupling heads are not very defined in terms of design. In contrast, the invention is based on the realization that improved weaving is possible in the weaving process, on the one hand by the use of a special twist mandrel and, on the other hand, by the provision of special traction stresses when wrapping. The bending hook has a longitudinal bending rounding, which helps to bend, and in addition a predetermined width. This width gives the bending spike a surface moment of inertia that helps the wrapping tension to prevent damage to the spike. The width of the twisting mandrel also defines the connecting eye. This creates connecting eyelets to which are attached connecting heads which are held firmly in the connecting eyelets because of the shape, so that the required strength with respect to the transverse forces and the flexural strength when folded is achieved, and at the same time the eyelet is large enough to engage made from a zipper strap fully demonstrates sufficient, even extreme flexibility. Wrapping tension leads to high speed of velocity, which has a positive effect on design. In accordance with the invention, tension-wrapped coupling heads are stabilized with thermal fixation without disturbing shape changes. It contributes to optimization when the movement of the weaving needle is adjusted in such a way that the pulling tension in the inner position of the weaving needle is increased by a factor between 1.2 and 2.5, with the plastic monofilament supporting the previously formed connecting part surrounded by the threads warp and / or weft. It goes without saying that the weft threads are strong enough, or that the number of basic threads is large enough.
V detajlih obstaja mnogo možnosti nadaljnjih izvedb ter specifikacij postopka glede na izum. Prednostna oblika izvedbe izuma je označena s tem, da se uporablja prevojni trn, katerega zaokrožitev robov ima premer okoli polovice debeline prevojnega trna. V okviru izuma je možno za plastično monovlakno uporabljati najrazličnejše sintetične materiale, ki so običajni pri izdelavi zadrg z nizi členkov zadrge, še posebej pa poliamidne in poliesterske materiale. Prečni presek plastičnih monovlaken je lahko okrogel. Posebno dobro oblikovane spojne glave nastanejo ob uporabi plastičnega monovlakna z v bistvu eliptičnim prečnim presekom, kjer je razmerje premerov 1:1,2 do 1:1,6 (mali premer : veliki premer). Tkanje se izvaja tako, da je pri spojnih glavah velika os eliptičnega prečnega preseka v zadrginem traku paralelna z vzdolžno osjo. Ob uporabi plastičnega monovlakna z eliptičnim prečnim presekom, je priporočljivo ob dovajanju k igli za tkanje plastičnemu monovlaknu s hladnim valjanjem spremeniti prečni presek iz okroglega v eliptičnega. Notranje napetosti, ki so ostale zaradi hladnega valjanja, pozitivno vplivajo na ovijanje, ki definira spojne glave. Razume se, da se pri uporabi plastičnih monovlaken z eliptičnim prečnim presekom namesto premera uporablja algebrska srednja vrednost mer male in velike osi .In detail, there are many options for further embodiments and specifications of the process according to the invention. A preferred embodiment of the invention is characterized by the use of a twisting mandrel whose rounding of the edges has a diameter of about half the thickness of the twisting mandrel. Within the scope of the invention, it is possible to use a wide variety of synthetic materials, which are common in the manufacture of zippers with a series of zip ties, and in particular polyamide and polyester materials, for plastic monofilament. The cross-section of plastic monofilaments may be circular. Particularly well-formed coupling heads are produced using a plastic monofilament with a substantially elliptical cross-section where the ratio of diameters is 1: 1.2 to 1: 1.6 (small diameter: large diameter). The weaving is carried out such that, for the connecting heads, the large axis of the elliptical cross section in the zipper strap is parallel to the longitudinal axis. When using a plastic monofilament with an elliptical cross-section, it is advisable to change the cross-section from a circular to an elliptical when feeding it to the cold-rolled plastic monofilament. The internal stresses left by the cold rolling have a positive effect on the wrapping defining the coupling heads. It is understood that when using plastic monofilaments with an elliptical cross section, the algebraic mean of the dimensions of the small and large axes is used instead of the diameter.
Nadalje bo izum pojasnjen s pomočjo shematskih risb, na kateri h:Further, the invention will be explained by means of schematic drawings in which h:

Na risbah 1 in 2 so vidni sestavni deli avtomata za izdelavo zadrginega traku 1 s tkanjem. Niti 2 osnove nosilnega traku in povezovalne niti 3 se vodijo tako, da nastaja tkanina. Igle 4 za tkanje uvajajo niti 5 votka nosilnega traku ter pri izvedbi po risbi 1 dvoje plastičnih monovlaken 6, oziroma pri izvedbi po risbi 2 eno plastično monovlakno 6.Figures 1 and 2 show the components of the automatic machine for producing the zipper tape 1 by weaving. Neither the 2 warp straps and the connecting thread 3 are guided to form a fabric. Weaving needles 4 introduce threads of 5 wefts of the carrier belt and, in the embodiment of drawing 1, two plastic monofilaments 6, or in the embodiment of drawing 2 one plastic monofilament 6.
Pogoji tkanja so urejeni tako, da se plastično monovlakno 6 z iglo 4 za tkanje, ki se stalno giblje od izhodnega k vhodnemu položaju, ovija okoli prevojnega trna 7, ki oblikuje členek zadrge. Pri tem se stalno iz plastičnih monovlaken 6 oblikuje niz členkov zadrge, členki 8 zadrge so vedno sestavljeni iz spojnih glav 9 in krakov 11 členkov zadrge. Ti kraki oblikujejo spojna ušesca 10. Združeni so s spojnimi deli 12, kar kaže tudi risba 4. Istočasno se niz členkov zadrge s pomočjo povezovalnih niti 3, kot tudi z nitmi 5 votka nosilnega traku, povezuje v nastajajoči nosilni trak 13. Vlečno napetost prihajajočega plastičnega monovlakna 6 je možno nastavljati s pogonskimi dovodnimi valji 14a za pritegovanje. Nanjo vpliva tudi izmenično gibanje igle 4 za tkanje in to tako, da je maksimalna vlečna napetost v zunanjem položaju igle 4 za tkanje, pri katerem se ustrezno plastično monovlakno 6 vleče k trnu. Pri tem se uporablja prevojni trn 7. Kako je narejen, se vidi ob primerjanju z ene strani risbe 3 ter z druge strani risb 4 do 6. Prevojni trn 7 ima skoraj pravokoten prečni presek, katerega debelina je za 10% do 20% manjša od premera ustreznega plastičnega monovlakna 6. Na strani spojnih glav ima vzdolžno prevojno zaokrožitev robov 15 ter širino, ki je za faktor od 1,75 do 3 večja od debeline. To daje prevojnemu trnu poseben površinski vztrajnostni moment in definira, kot kaže risba 6, velikost spojnih ušesc 10. Med drugim se vlečna napetost prihajajočega plastičnega monovlakna 6 še posebej nastavlja in to tako, kot je določeno v zahtevku 1. Pri tem so pomembne tudi vzmeti (14b) za izenačevanje napetosti, katere tudi vplivajo na dolžino dovoda. Zunanji položaj igle 4 za tkanje je tako prirejen, da se ob gibanju navzven vlečna napetost v plastičnem monovlaknu 6 poveča za faktor od 1,5 do 3, pri čemer se plastično monovlakno 6 naslanja na prevojni trn 7, kar se vidi na risbah 1 in 2. Gibanje igle 4 za tkanje navznoter je tako prirejeno, da se v notranjem položaju igle 4 za tkanje vlečna napetost v plastičnem monovlaknu 6 poveča za faktor od 1,2 do 2,5. Tukaj plastično monovlakno 6 podpira predhodno formiran spojni del 12, ki obdaja niti (2) osnove nosilnega traku, povezovalne niti 3 in/ali niti 5 votka nosilnega traku.The weaving conditions are arranged such that a plastic monofilament 6 with a weaving needle 4, constantly moving from the outlet to the inlet position, is wrapped around the twist mandrel 7, which forms the clasp. In this case, a series of zipper joints is formed permanently from plastic monofilaments 6, and the zipper members 8 always consist of connecting heads 9 and zipper arms 11. These arms form connecting lugs 10. They are joined to connecting lugs 12, as shown in Figure 4. At the same time, a series of joints are fastened by means of connecting threads 3, as well as threads 5 of the weft carrier belt, to the emerging carrier lane 13. Traction tension of the incoming the plastic monofilament 6 can be adjusted with the drive inlet rollers 14a for tightening. It is also affected by the alternating movement of the weaving needle 4, such that the maximum pulling tension is in the outer position of the weaving needle 4, in which the corresponding plastic monofilament 6 is drawn to the mandrel. In this case, the twist mandrel 7. How it is made can be seen by comparing on one side of drawings 3 and on the other side of drawings 4 to 6. The folding mandrel 7 has an almost rectangular cross-section whose thickness is 10% to 20% less than diameter of the corresponding plastic monofilament 6. On the side of the coupling heads, it has a longitudinal curvature of the edges 15 and a width that is by a factor of 1.75 to 3 larger than the thickness. This gives the bending mandrel a special surface moment of inertia and defines, as shown in Figure 6, the size of the connecting ears 10. Among other things, the tensile stress of the incoming plastic monofilament 6 is adjusted in particular as specified in claim 1. In this context, springs are also important. (14b) for equalizing the voltages, which also affect the supply length. The outer position of the weaving needle 4 is adapted to increase the pulling tension in the plastic monofilament 6 by a factor of 1.5 to 3 when moving outward, with the plastic monofilament 6 resting on the twist mandrel 7, as shown in Figures 1 and 2. The inward movement of the needle 4 of the weave needle is such that, in the inner position of the weave needle 4, the pulling tension in the plastic monofilament 6 is increased by a factor of 1.2 to 2.5. Here, the plastic monofilament 6 supports a preformed connecting piece 12 that surrounds the threads (2) of the base of the carrier belt, the connecting threads 3 and / or the threads of the weft of the carrier belt.
V primeru prednostne izvedbe izuma ima prevojni trn 7 prevojno zaokrožitev robov 15 polmera, ki je enak približno polovici debeline prevojnega trna 7. Rezultat uresničenega ovijanja poIn the case of a preferred embodiment of the invention, the twist mandrel 7 has a bend circumferential edge 15 radius equal to about half the thickness of the twist mandrel 7. The result of the actual wrap around
8izumu se vidi na risbah 4 in 5. Nastanejo zelo definirane spojne glave 9 pri globokem in efektivnem zapiranju z obliko. Lahko se, kot je prikazano na risbi 4, v spojnih glavah 9 dosežejo razmerja osi v obsegu med 1:2,6 in 1:3,6, odvisno od oblike trna in vlečne napetosti. Istočasno se na risbi 5 vidi naznačeno razmerje osi plastičnih monovlaken 6, kadar imajo eliptični prečni presek.8 of the invention is shown in Figures 4 and 5. Highly defined coupling heads 9 are formed upon deep and effective closure with the shape. As shown in Figure 4, axial ratios in the range of 1: 2.6 to 1: 3.6 can be achieved in the coupling heads 9, depending on the shape of the mandrel and the pulling tension. At the same time, Figure 5 shows the indicated axis ratio of the plastic monofilaments 6 when they have an elliptical cross section.
