Description
Przedmiotem wynalazku jest uchwyt odbiorczy igly w krosnie tkackim bezczólenkowym.The present invention relates to a needle receiving holder in a shameless weaving loom.
Znane sa uchwyty odbiorcze igly w krosnie tkackim bezczólenkowym, zawierajace stala szczeke wydluzo¬ na, zaopatrzona w hak zamocowany sztywno na igle, oraz szczeke ruchoma, obrotowa na pierwszej szczece i uruchamiana przez elementy sprezynujace, przy czym koniec szczeki ruchomej wspólpracuje z wewnetrzna powierzchnia haka w taki sposób, ze miedzy powierzchniami konca szczeki ruchomej haka powstaje luz w posta¬ ci szczeliny zwezonej w kierunku konca stalej szczeki. Nic watku, która w ruchu powrotnym igly wprowadzona zostaje w szczeline jest zaklinowana miedzy powierzchniami haka i szczeki ruchomej wspólpracujacymi ze soba i zostaje w ten sposób wprowadzona przez te szczeke w przesmyk.Needle receiving lugs are known in a shameless weaving loom that include a fixed elongated jaw. on, provided with a hook fixed rigidly on the needle, and a movable, rotating jaw on the first jaw and actuated by spring elements, the end of the movable jaw cooperating with the inner one the surface of the hook in such a way that a play is formed between the surfaces of the end of the movable hook of the hook the slit tapered towards the end of the steady jaw. Nothing about the thread that the needle entered on the return stays in the crack, it is wedged between the surfaces of the hook and the movable jaw cooperating with each other and is thus led through the jaw into the isthmus.
Niedogodnoscia znanych rozwiazan jest to, ze dzialanie uchwytu jest zadawalajace tylko w przypadku nici o stalych charakterystykach (na przyklad grubosc, struktura i tym podobne) lecz nie znajduje zastosowania do pracy w krosnie tkackim z nicmi watku o róznych charakterystykach.A disadvantage of the known solutions is that the operation of the handle is satisfactory only with threads with constant characteristics (e.g. thickness, structure, etc.) but not applicable to work in a weaving loom with thread threads of different characteristics.
Zadaniem wynalazku jest rozszerzenie mozliwosci technologicznych krosna tkackiego przez zapewnienie mozliwosci dzialania uchwytu przy uzyciu nici watku o róznych charakterystykach.The object of the invention is to extend the technological possibilities of a weaving loom by providing the possibility of operation of the handle using a thread of a thread with different characteristics.
Zadanie to osiagnieto wedlug Wynalazku w ten sposób, ze jedna ze wspólpracujacych ze soba powierzchni uchwytu ma wystep wzdluzny a druga powierzchnia ma szczeline wzdluzna sluzaca do umieszczania tego wystepu. Szczelina dla wystepu znajdujaca sie na jednej z powierzchni moze byc wykonana w postaci otwartego rowka. Jeden z boków haka zaopatrzony jest w element zatrzymujacy nic watku wykonany w postaci plaskiej sprezyny przymocowanej do stalej szczeki.According to the invention, this task was achieved in such a way that one of the surfaces cooperating with each other the handle has a longitudinal projection and the other face has a longitudinal slot for receiving it performance. The gap for the protrusion on one of the surfaces can be made open groove. One of the sides of the hook is equipped with a thread retaining element made in a flat form a spring attached to the fixed jaw.
Dzieki temu ukladowi, w którym jedna ze wspólpracujacych ze soba powierzchni zaopatrzona jest w wystep, a druga w rowek do umieszczania tego wystepu, nic watku jest przytrzymywana w sposób pewny przez zaklinowanie.Thanks to this system, one of the cooperating surfaces is provided with into the protrusion and the other into the groove for receiving the protrusion, nothing of the thread is held securely by wedging.
Przedmiot wynalazku przedstawiony jest w przykladach wykonania na rysunku, na którym fig. 1 przedsta¬ wia igle wraz z uchwytem wedlug wynalazku w przekroju wzdluznym, fig. 2 - uchwyt z fig. 1, fig. 3 - uchwyt z fig. 2 w przekroju poprzecznym wzdluz linii III-IIIj fig. 4 - igle wraz z uchwytem w innym wykonaniu wyna¬ lazku w przekroju wzdluznym, fig. 5 - szczeke ruchoma uchwytu igly z fig. 4, w rzucie poziomym a fig. 6 - uchwyt z fig. 2 w rzucie poziomym wedlug linii II—II pokazujacy element zatrzymujacy nic watku.2 101 953 Uchwyt przedstawiony na rysunku zawiera igle 1 oraz system sterujacy rozwarcie uchwytu, oznaczony w calosci jako 2.The subject of the invention is illustrated in the drawing in which Fig. 1 is shown in the following examples a needle with a handle according to the invention in a longitudinal section, fig. 2 - handle from fig. 1, fig. 3 - handle 2, a cross-section along the line III-IIIj, FIG. 4, needles with a holder according to another embodiment of the invention Fig. 5 - movable jaw of the needle holder from Fig. 4, in a horizontal view, and Fig. 6 - the handle from Fig. 2 in a horizontal projection according to line II-II showing the element that stops the thread. 2 101 953 The handle shown in the drawing comprises a needle 1 and a control system for the opening of the handle, marked entirely as 2.
Igla 1 wprowadzana jest w ruch posuwisto-zwrotny wzdluz grzebienia 3 krosna tkackiego i w tym celu zaopatrzona jest w klocek 4 przeznaczony do przesuwania sie wzdluz przedniej plaszczyzny grzebienia. Igla 1 pociagana jest swym zewnetrznym koncem, za pomoca lacznika 5, np. lacznika przegubowego za posrednictwem odpowiedniego systemu szczególowo opisanego we francuskim opisie patentowym nr 1290867.Needle 1 is driven in a reciprocating motion along the comb 3 of the weaving loom and for this purpose it is provided with a block 4 designed to slide along the front plane of the comb. Needle 1 is pulled by its outer end by means of a link 5, e.g. an articulated joint via a suitable system described in detail in French Patent No. 1,290,867.
Igla 1 zaopatrzona jest w uchwyt 6 skladajacy sie ze szczeki stalej 7 polaczonej z korpusem 8 uchwytu oraz ze szczeki ruchomej 9 zamontowanej wahliwie na stalej szczece 7 za pomoca osi 10.Needle 1 is equipped with a handle 6 consisting of a fixed jaw 7 connected to the body 8 of the handle and from a movable jaw 9 pivoted on a fixed jaw 7 by means of an axis 10.
Uchwyt 6 jest elastycznie pociagany do polozenia zamknietego, to znaczy do polozenia zacisku nici watku 11 przez sprezyne 12, której jeden koniec oparty jest o wrzeciono 13 i której czesc srodkowa oparta jest o srube regulacyjna 14.The handle 6 is flexibly pulled to a closed position, that is, to the position of the thread clamp of the thread 11 through the spring 12, one end of which rests against the spindle 13 and whose middle part rests against the screw Regulatory 14.
Szczeka ruchoma 9 jest polaczona z dzwignia wystajaca 15, uruchamiana w kierunku rozwarcia uchwytu, przez system sterowania rozwarcia taki jak krazek 16, wówczas gdy igla znajduje sie w poblizu koncowego punktu swego przesuwu, poza przesmykiem.The movable jaw 9 is connected to the projecting lever 15, operated in the direction of opening the handle, by an opening control system such as disc 16 when the needle is near the end point of its displacement, beyond the isthmus.
Igla odbierajaca 1 zaopatrzona w uchwyt przechodzi w srodku przesmyku krosna tkackiego na spotkanie igly doprowadzajacej, która podaje nic watku 16 az do konca przesmyku, gdzie uchwyt ulega rozwarciu.The receiving needle 1 provided with a holder passes in the center of the shed of the weaving loom to the meeting a feed needle that feeds nothing through thread 16 until the end of the shed where the handle opens.
Szczeka stala 7 ma ksztalt haka a szczeka ruchoma 9 zawiera zgodnie z wynalazkiem na swym koncu plytke 17 wspólpracujaca, w celu zaciskania nici watku, z bokiem wewnetrznym 18 wyostrzonego konca haka.The fixed jaw 7 has the shape of a hook and the movable jaw 9 according to the invention has at its end a mating plate 17 for clamping the thread of the weft with the inner side 18 of the sharpened end of the hook.
Jak przedstawiono na rysunku, w polozeniu zamknietym uchwytu, górna powierzchnia plytki 17 tworzy pewien kat w stosunku do boku 18 haka, przy czym kat ten jest otwarty w kierunku tylnej czesci igly. Na flg. 1, ten otwarty kat umozliwia uchwycenie nici podczas wycofania sie igly odbierajacej i powoduje zaklinowanie nici gdy jest ona pociagana przez igle odbierajacej. Kat miedzy górna czescia plytki a bokiem haka moze byc dopasowany na przyklad przez zdjecie warstwy metalu, w zaleznosci od rodzaju stosowanej nici.As shown in the drawing, in the closed position of the handle, the upper surface of the plate 17 forms an angle with respect to the side 18 of the hook, the angle being open towards the rear part of the needle. On flg. 1, this open angle grips the thread as the receiving needle retracts and causes the thread to jam when it is pulled by the receiving needle. The angle between the top of the plate and the side of the hook may be adjusted, for example, by removing the metal layer, depending on the type of thread used.
Jak przedstawiono na fig. 2, bok haka przewiercony jest otworem wzdluznym, do którego wprowadzony jest czesciowo, w polozeniu zamknietym uchwytu, waski koniec plytki 17, który stanowi wystep wspólpracuja¬ cy z tym otworem.As shown in Fig. 2, the side of the hook is drilled with a slotted hole into which it is inserted it is partially, in the closed position of the handle, the narrow end of the plate 17, which is the projection of the mating with this hole.
Uklad taki zapewnia, niezaleznie od zaciskania nici miedzy szczekami, dodatkowe zaklinowanie, czyli wglebienie tej nici (fig. 3), które jest bardzo skuteczne w utrzymaniu nici bez wzgledu na jej cechy charaktery¬ styczne.Such a system ensures, regardless of the clamping of the thread between the jaws, additional wedging, i.e. indentation of this thread (Fig. 3), which is very effective in retaining the thread, regardless of its characteristics tangents.
Podczas rozwarcia uchwytu, to znaczy wówczas, gdy dzwignia 15 opiera sie o krazek 16, uchwyt ulega rozwarciu i plytka 17 oddala sie od boku haka na tyle aby jej wystajacy koniec uwolnil sie calkowicie od szczeliny 19, uwalniajac tym samym calkowicie nic, bez wzgledu na jej grubosc. Jest rzecza oczywista, ze wzdluzna szczelina 19 moze byc zastapiona rowkiem lub innym odpowiednim odcinkiem wglebionym wykona¬ nym na wewnetrznej powierzchni boku haka.When the handle is opened, that is, when the lever 15 abuts against the pulley 16, the handle subsides opening and the plate 17 moves away from the side of the hook so much that its protruding end is completely free from the slots 19, thereby freeing absolutely nothing, no matter what its thickness. It is obvious that the longitudinal slot 19 may be replaced by a groove or other suitable deepened section on the inside of the side of the hook.
W przykladzie wykonania przedstawionym na fig. 4, czesci wglebione i wystajace na szczekach stalej i ruchomej rozmieszczone sa odwrotnie niz w wykonaniu przedstawionym na fig. 1, 2 i 3, to znaczy, ze po¬ wierzchnia wewnetrzna 18 boku haka stalego zawiera wystep wzdluzny 20 wystajacy a plytka 17 ma przewier¬ cona szczeline 21 (fig. 5), z która wspólpracuje wystep 20 w polozeniu zamknietym uchwytu, uklad taki zapewnia równiez zaklinowanie nici watku tak jak opisano powyzej.In the embodiment shown in Fig. 4, the recessed and protruding parts on the jaws of the fixed jaw and the mobile are arranged inversely to the embodiment shown in Figs. 1, 2 and 3, i.e. the outer inner side 18 of the fixed hook has a long projection 20 and the plate 17 has a drill hole cone slot 21 (Fig. 5) with which the projection 20 cooperates in the closed position of the handle, such an arrangement also ensures that the weft threads are wedged as described above.
Czesci wglebione oraz wystajace moga oczywiscie byc wykonane przez dodatkowe ksztaltowniki w ksztal¬ cie litery V bardziej lub mniej rozwarte w stosunku do boku haka lub plytki.The sunken and protruding parts can of course be made by additional shapes in the shape of the cut of the V more or less open to the side of the hook or plate.
Uchwyt wedlug wynalazku ma element zatrzymujacy nic watku 11, który ma postac plaskiej sprezyny 22 (fig. 6), zmontowanej na jednym z boków haka 7 i dociskajacej nic do korpusu z jednoczesnym hamowaniemjej przesuwu. Plaska sprezyna moze byc korzystnie przymocowana przez nit sluzacy jako os 10 szczeki ruchomej w szczece stalej.The handle according to the invention has a thread retaining element 11 in the form of a flat spring 22 (fig. 6), mounted on one of the sides of the hook 7 and pressing the nothing against the body while braking it travel. The flat spring can advantageously be secured by a rivet serving as the axis of the movable jaw in a fixed jaw.
