Description

Przedmiotem wynalazku jest urzadzenie wprowadzajace watek do przesmyku krosna pneumatycznego.Znane urzadzenie do wprowadzenia watku do przesmyku oparte sa na systemie konfuzoro- wego wprowadzania watku. W jednym ze znanych rozwiazan konfuzorjest mocowany sztywno do belki bidla, nieruchomej wzgledem plochy, której os wahan jest cofnieta w glab krosna. W urzadzeniu tym przy ruchu bidla do przodu, przy którym nastepuje dobijanie watku, konfuzor opada i opuszcza przesmyk wchodzac pod tkanine. Odpowiednio ruchowi bidla do tylu odpowiada podnoszenie konfuzora wraz z plocha i wprowadzenie go do przesmyku. Wadatego urzadzeniajest koniecznosc dobijania watku górna czescia plochy.W innym znanym urzadzeniu konfuzor umieszczony jest na oddzielnych wahaczach, które wprowadzaja konfuzor w przesmyk niezaleznie od ruchu bidla. Urzadzenie to wymaga stosowania dodatkowego napedu konfuzora.Urzadzenie wprowadzajace watek do przesmyku krosna pneumatycznego wedlug wynalazku jest wyposazone w krzywke wewnetrzna o zarysie sinusoidalnym, zamocowana nieruchomo do ramy krosna, przy czym w kanale krzywki znajduje siejeden koniec popychacza na którego drugim koncu umieszczony jest konfuzor. Popychacz jest umieszczony suwliwie w prowadnicy zamocowa¬ nej na stale do bidla.Krzywka o zarysie sinusoidalnym zastosowana w urzadzeniu wedlug wynalazku nadaje popy- chaczowi wraz z konfuzorem ruch harmoniczny w plaszczyznie plochy zapewniajac optymalna dynamike tych elementów.Urzadzenie wedlug wynalazku jest szczególnie przydatne w przypadku modernizacji krosien czólenkowych na krosna pneumatyczne, zapewniajac dokladnie modernizacji krosien bez konie¬ cznosci ich demontazu oraz bez zmiany kinematyki bidla.Przedmiot wynalazku jest przedstawiony w przykladzie wykonania na rysunku schema¬ tycznym.Urzadzenie wedlug wynalazkujest wyposazone w krzywke wewnetrzna 1 o zarysie sinusoidal¬ nym, zamocowana do ramy krosna nie uwidocznionej na rysunku. W kanale 2 krzywki 1 jest umieszczony toczek popychacza 3 zakonczonego konfuzorem 4. Popychacz 3 jest osadzony w prowadnicy 5 zamocowanej do wspornika bidla 6 polaczonego plocha 7. Na rysunku przedsta-2 145 115 wiono dwa skraje polozenia bidla 6, przy czym polozeniu I odpowiada faza wprowadzenia watku 8 do przesmyku utworzonego z osnowy 9, natomiast polozenie II przedstawia faze dobijania watku 8 do krawedzi tkaniny 10.Po wprowadzeniu watku 8 do konfuzora 4 znajdujacego sie w przesmyku, /polozenie I/, nastepuje ruch bidla 6 dobijajacy watek 8, podczas którego popychacz 3 konfuzora 4 wykonuje ruch opadajacy w plaszczyznie bidla 6, wymuszony krzywka 1, tak, ze podczas dobicia watku 8 /polozenie bidla II/, konfuzor 4 jest schowany pod tkanina 10. Przy ruchu powrotnym bidla 6, z polozenia II do polozenia I, krzywka 1 unosi popychacz 3 powodujac ponowne wprowadzenie konnfuzora 4 do przesmyku zajmujac pozycje wyjsciowa.Zastrzezenia patentowe Urzadzenie wprowadzajace watek do przesmyku krosna pneumatycznego, zawierjace konfu¬ zor, znamienne tym, ze jest wyposazone w krzywke wewnetrzna (1) o zarysie sinusoidalnym, zamocowana nieruchomo na krosnie, przy czym w kanale (2) krzywki (1) znajduje sie jeden koniec popychacza (3), na którego drugim koncu jest zamocowany konfuzor (4), nadto popychacz (3) jest umieszczony w prowadnicy (5) zamocowanej na stale do bidla (6).Pracownia Poligraficzna UPPRL. Naklad lOOegz.Cena 400 zl PLThe subject of the invention is a device for introducing the thread into the shed of a pneumatic loom. The known device for introducing the thread into the shed is based on the confusor thread introduction system. In one of the known solutions, the confusor is rigidly attached to the beam of a water bottle, immobile in relation to the slope, the swing axis of which is retracted into the loom. In this device, when the water bottle moves forward, at which the thread is tapped, the confusor drops and leaves the shed, entering under the fabric. Correspondingly, the backward movement of the water bottle corresponds to lifting the confusor together with the spit and introducing it into the isthmus. In another known device, the confusor is placed on separate rockers, which introduce the confusor into the shed, regardless of the movement of the water bottle. This device requires the use of an additional confusor drive. The device for introducing threads into the shed of a pneumatic loom, according to the invention, is equipped with an internal cam with a sinusoidal profile, fixed to the frame of the loom, and in the cam channel there is one end of the pusher on the other end of which is a confusor. The pusher is placed slidably in the guide fixed permanently to the bottle. The sinusoidal cam used in the device according to the invention gives the pusher along with the confusor harmonic movement in the plane of the slope ensuring optimal dynamics of these elements. The device according to the invention is particularly useful in the case of modernization shuttle looms for pneumatic looms, ensuring the exact modernization of the looms without the need to dismantle them and without changing the kinematics of the bottle. The subject of the invention is shown in the example of the embodiment in the schematic drawing. to the frame of the loom not shown in the picture. In the channel 2 of the cam 1 there is a pusher 3 ending with a confusor 4. The pusher 3 is embedded in the guide 5 attached to the bottle support 6 of the connected ploch 7. In the drawing, two edges of the bottle 6 position are shown, where position I corresponds to the phase inserting the thread 8 into the shed made of warp 9, while position II shows the phase of tapping the thread 8 to the edge of the fabric 10. After inserting the thread 8 into the confusor 4 located in the shed, / position I /, the movement of the bottle 6 tapping the thread 8 takes place, during which the pusher 3 of the confusor 4 makes a descending movement in the plane of the bottle 6, forced cam 1, so that when tapping the thread 8 / position of the bottle II /, the confusor 4 is hidden under the fabric 10. When the bottle 6 returns, from position II to position I, the cam 1 lifts the pusher 3 causing the re-insertion of the confusor 4 into the shed, taking the starting position. pneumatic, containing a confusor, characterized by the fact that it is equipped with an internal cam (1) with a sinusoidal profile, fixed on the loom, and in the channel (2) of the cam (1) there is one end of the pusher (3), on which the confusor (4) is attached to the other end, moreover the pusher (3) is placed in the guide (5) permanently attached to the water bottle (6).
