(54) РОГУЛЬКА РОВНИЧНОЙ МАШИНЫ(54) ROLLER OF THE FLAT MACHINE

Изобретение относитс к текстильной промышленности и касаетс рогулек дл ровничных машин любых типов.FIELD OF THE INVENTION The invention relates to the textile industry and relates to rolls for any type of roving frame.

Известна рогулька ровничной машины , содержаща установленные на голов ке балансную ветвь и полную рабочую ветвь с размещенной на конце лапкой, имеющей нитеводитепь в виде стержн и лопатку, на которой вдоль стержн нйтеводител выполнен направл ющий желобок конической формы, обращенный острием к свободному концу лопатки, и глазок, расположенный между желобком и нитеводителем , при этом ось желоба и центр, глазка наход тс на одной пр мой, а нитеводитепь выполнен в виде плоской спирали 11,The rovnichnaya machine flyer is known, containing a balanced branch installed on the head and a full working branch with a foot placed on the end, having a yarn in the form of a rod and a blade on which a guide groove of conical shape is made along the stem of the scapula, and the eye located between the groove and the yarn feeder, with the axis of the gutter and the center, the eye of the eye is on the same straight line, and the thread guide is made in the form of a flat spiral 11,

Недостатком данной рогульки вл етс бесконтрольное движение ровницы на участке глазок-линии контакта лопаточки с качущкой, что приводит к по влению скрытой выт жки. Кроме того, рогулька характеризуетс недостаточной плотностью намотки ровницы на катушку, повы-The disadvantage of this flyer is the uncontrolled movement of the roving in the area of the eye-line of the contact of the spatula with the rocker, which leads to the appearance of a hidden extract. In addition, the flyer is characterized by insufficient density of winding of the roving on the coil, increasing

шенной скрытой выт жкой и обрывностью ровницы вследствие нестабильного попс жени ровницы на стенке отверсти по мере наработки съема.the hidden latent stretching and breakage of the roving due to the unstable pop of the roving on the wall of the hole as they are being removed.

Цель изобретени - снижение обрывности ровницы за счет уменьшени скрытой выт жки ровницы в зоне перехода ее с лопатки на катушку машины.The purpose of the invention is to reduce the breakage of the roving due to the reduction of the latent exhaust of the roving in the zone of its transition from the blade to the machine reel.

Эта цель достигаетс тем, что в роto гульке ровничной машины, содержащей установленные на головке балансную ветвь и полую рабочую ветвь с размешенной на конце лапкой, имеющей нитеводитель в виде стержн и лопатку, на которой вдоль This goal is achieved by the fact that in a roto guul of a roving machine containing a balanced branch mounted on the head and a hollow working branch with a foot placed at the end and having a yarn guide in the form of a rod and a paddle along which

15 стержн нитеводител выполнен направл ющий Желобок конической формьт, обрашенный острием к свободному концу лапкв, и глазок, расположенный между желобком и нитеводителем, глазок расположен так, 15 of the yarn guide rod is made a guide groove of a conical shape, edged with a tip to the free end of the lapws, and a peephole located between the groove and the yarn feeder, the peephole is positioned so that

Claims

The guide rod is arcuate in the plane perpendicular to the axis of rotation of the flyer, and is curved along the BIN pin of the axis of the flyer. FIG. 1 shows the horn in working position; FIG. -a section A-phage, 1; Ia 4ng. 3: flyer folder A flyer for a rovnichnaya machine contains sleeve 1 with Head 2, on which a balanced solid branch 3 and the working branch 4 are installed, with the foot 5 placed at its end, 5 "The last thread guide 6 in the form of a rod and a shovel-: ku 7 ( Fig. 1). The core of the yarn feeder 6 is arcuate in the plane perpendicular to the axis of the flyer and is curved along a helix along its axis, which the linerBHo passes into the blade 7 (Figures 2 and 3). - On the blade 7 on its inner side along the rod of the iodineer 6, the guide groove 8 (phage 3) is conical, facing with the tip of the free end m} of the patch 7, and the eye 9 located between groove 8 and the yarn guide 6 so that the axis of the groove 8 passes tangentially to the peephole 9. When refueling the machine, the rovnip is pulled through the HEAD1dG of the flyer 2 and BBO DITS into the under working 4 flyers. Next, the roving 1O is rotated by the rotational movement inside the coils of the yarn guide 6 and through the peephole 9 is fed to the coil 11. After refilling the machine, the flyer is rotated and the level 10 is pulled through it, and the rotate 10 the yarn feeder 6 it moves along the inner working surface of its turns so that the area of their contact is of the smallest value, which reduces the seat of friction, and consequently, reduces weight. gagchinu hidden extract roving. In addition, during the passage of the roving 1O through the turns of the yarn guide 6, there is a sharp moment, which creates a positive value of the false twist of the i-roving in the hollow branch 4 of the flyer. The magnitude of the additional torque during the time of the accumulation of the solid material remains constant, since the conditions for the passage of the rove 1O through the coils of the yarn feeder-6 at this time remain unsteady. Upon exiting the nitevodnel 6, the roving 10 through the peephole 9 is brought to the coil 11, picks up the spatula 7, the peephole 9 and the direction of the groove 8. Since the axis of the groove 8 coincides with the tangent bottom edge of the peephole 9 and is aligned with the axis of the thread guide B, The roving 10 bends around the lower edge of the eye 9 as it moves, thus ensuring control of its fibers. At the same time, additional HOJVmalities arise in the roving and the radius of curvature of its fibers increases, which leads to an increase in the strength of this section of level 1. In addition, with this mutual arrangement of the thread guide 6, the groove 8 Ef of the eye 9, the latter works as a toroidal fixed reel and creates an additional false twist value, while the tension value rotates slightly), and an additional false twist value is created in the railing branch, which increases its strength and reduces latent stretching, and also contributes to an increase in the sealing effect on the rove. Eliminating the uncontrolled movement of the roving on the site of the eye-line of the contact of the spatula with the coil, as well as raising and stabilizing the rotor in the hollow branch, provided by a long mutual arrangement of the yarn feeder, eye and groove, reduce the breakage of the roving on the machine, reduce the hidden Kytzhku roving and increase the density of the package. Claims of the invention 1. A flyal of a roving machine, containing a ba-gan branch on the head and a feed working branch with a tab on the end having. thread the 1 in the form of a rod and a spatula,. where a conical shaped groove is made along the yarn guide rod, directed at the free end of the scapula, and an eye located between the skirt and the yarn guide, due to the fact that by reducing the latent drawdown of the level-species in the zone of its transition from the blade to the machine roll, the eye is positioned so that the axis of the groove passes tangentially to the eye.
