Description

Vynález rieši konštrukciu viaczákrutového vřetena pre skanie nekonečného vlákna a priadze vo vláknérenskom a textilnom priemysle.The invention solves the construction of a multi-twist spindle for twisting continuous filaments and yarns in the fiber and textile industries.

Sú známe rožne konštrukcie jednozákrutových a dvojzékrutových, trojzákrutových a viaczákrutových vretien pře skanie nekonečného vlákna a priadze. U jednozákrutových vretien sa spracovávaná předloha točí a skané vlákno ss z vřetena odtahuje. U krýdlových a prstencových vretien sa vlákno sa do vřetena navíja. Tieto jednostopové vretená dávajú na jednu obrátku jeden zákrut. U dvojzékrutových, trojzékrutových a viaczákrutových vretien je předloha uložené vo vřetene, z ktorého sa vlákno, alebo priedza odtahuje a dvomi, tromi, alebo viao zákrutami na jednu obrátku vřetena. Všetky jednozákrutové, dvojzákrutové a trojzákrutové vretená majú nízku produktivitu práce kvoli malej tvorbě zákrutov a malému návinu pracovnej předlohy. Konštrukcia týchto vretien neumožňuje vytvářet návin velkokapacitněj kónickéj cievky, pri vysokej odtahovéj rýchlosti a vysokej tvorbě zákrutov. Nízká odtahová rýchlost je viazaná na obrátky jednozákrutového, dvojzákrutového a trojzákrutového vřetena, čo sa v prevádzke prejaví nízkým koefioientom využitia zastavenéj ploohy, vysokými investičnými a prevádzkovými nákladmi. Viaczékrutové vretená majú štyri unášače, čo sposobuje zvýšené pnutie spracovávaného materiálu.Spiral structures of single-twist and double-twist, triple-twist and multi-twist spindles are known to span continuous filaments and yarns. In single-turn spindles, the workpiece is rotated and the twisted fiber DC is pulled from the spindle. For vane and ring spindles, the fiber is wound into the spindle. These single-track spindles give one turn per turn. For double-twisted, triple-twisted and multi-twisted spindles, the original is housed in the spindle from which the fiber or yarn is pulled and two, three, or more twists per spindle revolution. All single-, double- and triple-twist spindles have low work productivity due to low twist formation and low work pattern winding. The construction of these spindles does not make it possible to wind the large-capacity conical coil at high draw-off speed and high twist formation. The low draw-off speed is linked to the revolutions of the single-, double- and triple-twist spindles, which results in low coefficient of utilization of the built-up area, high investment and operating costs. Multi-twist spindles have four grippers, which causes increased stress on the material to be processed.

Uvedené nedostatky odstraňuje viaczékrutové vřeteno, ktorého podstata spočívá v tom,These shortcomings are eliminated by a multi-twist spindle, which is based on

Obe Sáeti sú spojené cez variátor, pričom zmysel ich otáSania je opačný. K telesu variátora a k telesu ložiska v ktorom je uložený druhý hnaný hriadeí, opatřený dalším vonkajším unášačom, je pevne uchytená jednak vanička, ako aj protilehle uspořiadaný hlavný kryt.199 872 hijackers. One of the driven shafts is divided into a primary part and an outer gripper retained and a secondary part provided with an inner gripper. The two seeders are connected via a variator, the sense of which is reversed. A tray as well as an opposing main housing are fixedly attached to the variator housing and to the bearing housing in which the second driven shaft is provided, with an additional external carrier.

Výhoda zariadenia, ktoré je predmetom ochrany, je v tom, že i pri menšom počte unášašačov sa zabezpečí funkcia viaczákrutového vřetena. Výsledkem přitom je znížénie počtu třecích ploch, a tým zmenšenie odtahovéj sily, čo zabezpečuje spracovávanie vlákien, pre rizika pretrhávania,čiže proces spracovávania vlákien je účinnější a zároveň menej náročný na energiu.The advantage of the device to be protected is that even with a smaller number of carriers, the function of the multi-twist spindle is ensured. The result is a reduction in the number of friction surfaces, and thus a reduction in the pulling force, which ensures fiber processing, due to the risk of breakage, so that the fiber processing process is more efficient and at the same time less energy intensive.

Příklad viaczékrutového vřetena pódia vynálezu je znázorněný na pripojenom výkrese, na ktorom je nakreslené schématicky v nárysnom řeze.An example of a multi-twist spindle according to the invention is shown in the accompanying drawing, in which it is schematically shown in elevation.

Viaczákrutové vřeteno pozostáva zo základného rému opatřeného stojinami 1. V týchto sú uchytené ložiská, v ktorých je ulóžený jednak hnací hriadel ,2, ako aj hnané hriadele J.The multi-twist spindle consists of a base frame provided with uprights 1. In these, bearings are mounted in which both the drive shaft 2 and the driven shafts J.

Hnací hriadel 2 je spojený s hnaným hriadelom χ prostredníctvom primárného převodu 4 napr. řemenového. V osi hnaných hriadeíov χ medzi nimi je usporiadaná předloha χ. Jeden z hnaných hriadeíov χ je delený na dve časti a to primárnu, s uchyteným vonkajším unášačom 6, a sekundárnu Sasi opatrenú vnútorným unášačom χ. Obidve časti sú spojené cez variátor 8 a ich zmyeol otáčanie je vzájomne opačný. Další vonkajší unášeč 6 je súčastou druhého hnaného hriadela χ. Předloha χ je obklopená vaničkou χ a protilehle usporiedaným hlavným krytom 10. ktorý ako aj vanička χ je uchytený jednak k telesu 11 ložiska hnaného hridela χ na jednej straně, ako aj k teleau variátora 8na straně druhej.The drive shaft 2 is connected to the driven shaft χ by means of a primary transmission 4 e.g. belt. In the axis of the driven shafts χ is a pattern χ arranged between them. One of the driven shafts χ is divided into two parts, the primary one, with the outer carrier 6 attached, and the secondary shaft provided with the inner carrier χ. The two parts are connected via the variator 8 and their rotation is reversed. Another outer carrier 6 is part of the second driven shaft χ. The slide χ is surrounded by a tray χ and a opposing main cover 10 which, as well as the tray χ, is attached both to the drive shaft bearing housing 11 on one side and to the variator body 8 on the other.

Funkcia vřetena je nasledovná: Pomocou elektromotore sa roztočí hnací hridel 2, ktorý prostredníctvom primárných prevodov £ zabezpečuje pohyb hnaných hriadeíov χ. Zmysel otáčanie časti děleného hnaného hriadela musí byt opačný, čo je realizované variátorom 8. Vlákno je potom odtahované z předlohy χ cez brzdu 12, kladku 13. kladku 1£ vnútorného unášača χ na galetu 15 a získá prvé dva zákruty na jednu obrátku. Prechodom vlákna cez ňalšiu kladku 13 na vonkajší unášač 6 získá ňalšie dva zákruty na jednu obrátku, pričom potom prechádza cez zarážku pretrhu 16 na navíjecí mechanizmus. Vanička χ a krytom 10 plnia funkciu antibalóna a zároveň znižujú hlučnost vřetena.The function of the spindle is as follows: By means of an electric motor, the drive shaft 2 is rotated which, by means of the primary gears 6, ensures the movement of the driven shafts χ. The sense of rotation of the part of the split driven shaft must be the opposite, which is realized by the variator 8. The fiber is then pulled from the pattern χ through the brake 12, the roller 13 of the inner carrier pulley χ on the pallet 15 and obtains the first two turns. By passing the filament through the other pulley 13 to the outer entrainer 6, it obtains two more twists per turn, then passes through the break stop 16 on the winding mechanism. The tray χ and cover 10 serve as an anti-balloon while reducing the noise of the spindle.

Viaczákrutové vřeteno možno s výhodou použit pri spracovávaní nekonečného vlákna, najma textilnej priadze vo vlákérenstve a textilnom priemysle.The multi-twist spindle can be advantageously used in the processing of continuous filament, in particular textile yarn in the fiber industry and the textile industry.
