Abstract

Predmetom riešenia je odvalovací pohon navíjacieho vřetena, umožňujúci návin vysokohmotnostných návinov, najma syntetických vláken a zabezpečuje přesný návin počiatočných vrstiev návinu. To sa dosahuje tým, že hnací odvalovací válec je opatřený třecím krúžkom upevněným přírubou. Tento je priamo pritláčaný na vřeteno s nasunutou dutinkou v priestore mimo dutinky. Dutinka je umiestnená mimo dotyku hnacieho odvalovacieho valca a vřetena.The subject of the solution is a winding spindle roll drive, enabling the winding of high-weight windings, especially synthetic fibers, and ensuring accurate winding of the initial layers of the winding. This is achieved by the fact that the drive roll roll is provided with a friction ring fixed by a flange. This is directly pressed onto the spindle with a sleeve inserted in the space outside the sleeve. The sleeve is located outside the contact between the drive roll roll and the spindle.

Description

(54) Pohon navíjacieho vřetena pre navíjacie zariadenia(54) Winding spindle drive for retractors

Predmetom riešenia je odvalovací pohon navíjacieho vřetena, umožňujúci návin vysokohmotnostných návinov, najma syntetických vláken a zabezpečuje přesný návin počiatočných vrstiev návinu. To sa dosahuje tým, že hnací odvalovací válec je opatřený třecím krúžkom upevněným přírubou. Tento je priamo pritláčaný na vřeteno s nasunutou dutinkou v priestore mimo dutinky. Dutinka je umiestnená mimo dotyku hnacieho odvalovacieho valca a vřetena.The object of the solution is the rolling drive of the winding spindle, which enables the winding of high-weight windings, especially synthetic fibers, and ensures the exact winding of the initial layers of winding. This is achieved in that the drive roller is provided with a friction ring attached to the friction ring. This is directly pressed onto the spindle with the sleeve inserted in the space outside the sleeve. The sleeve is located outside the contact of the drive roller and the spindle.

Predmetom vynálezu je pohon navíjacieho vřetena navijácích zariadení pre navíjanie prírodných a chemických vláken, nití a pásiek spůsobom neregulovaného návinu.It is an object of the invention to drive a winding spindle of winding devices for winding natural and chemical fibers, yarns and tapes in an unregulated winding.

Pre kvalitnú stavbu návinu válcového tvaru odvalovým spůsobom sa vyžaduje, aby hnací odvalový válec prenášal třením na vřeteno otáčky bez sklzu a bez nežiadaných vibrácií vřetena.In order to build up a cylindrical shape in a rolling manner, it is required that the drive rolling roller transmits friction to the spindle without slipping and without unwanted spindle vibrations.

Doteraz známe pohony vretien navijácích zariadení pomocou hnacieho valca sú převedené tým spůsobom, že hnací válec sa pritláča na dutinku volnoběžného vřetena, čím ho roztočí a po navedení vlákna může nastat samotný proces navíjania.The prior art spindle drives of the winding devices by means of a drive roller are converted in such a way that the drive roller is pressed against the idle spindle sleeve, thereby rotating it and after winding the fiber, the winding process itself can take place.

Nevýhodou tohoto sposobu je to, že vplyvom nepresne vyrobených dutinlek, ktoré sú vyrobené z papiera, připadne vrstvených umělých hmůt, nastáva hned' od začiatku navíjania vibrácia vřetena s nekontrolovatelnými sklzmi, ktorá sa s narastajúclm návinom zhoršuje. Nežiaduca vibrácia sa prenáša z vřetena na celé navíjacie zariadenie, čo má nepriaznivý vplyv jednak na konštrukciu zariadenia a následné na samotný návin, vykazujúci přepady vlákna hlavně na celách cievky,A disadvantage of this method is that, due to inaccurately manufactured cores made of paper or laminated plastics, the spindle vibrates with uncontrollable chutes from the start of winding, which deteriorates with increasing winding. The unwanted vibration is transmitted from the spindle to the entire winding device, which has an adverse effect on the construction of the device and consequently on the winding itself, showing the overflows of the filament mainly on the whole spool,

Tieto nevýhody odstraňuje pohon navíjacieho vřetena, ktorý má hnací válec riešený tak, že jeho predížena válcová část presahujúca dížkový rozměr návinu, je na jednom konci opatřená třecím krúžkom so zváčšeným priemerom, ktorý sa opiera priamo o volnoběžné vřeteno mimo dutinky, čím sa odstráni počiatočný zdroj vibrácií. Je přitom výhodnejšie, keď sa tento krúžok vyrobí z pružného materiálu s vysokým koeficientom trenia, umožňujúcim spojenie odvalového valca s vretenom bez hrubých nárazov a rýchly rozběh bez výrazných sklzov.These drawbacks are overcome by a winding spindle drive having a drive roller designed such that its extended cylindrical portion extending beyond the length dimension of the winding is provided at one end with an enlarged diameter friction ring that rests directly on the idle spindle outside the tube to remove the initial source vibration. Preferably, the ring is made of a resilient material with a high coefficient of friction, allowing the roll-to-spindle to be coupled to the spindle without coarse impacts and rapid start-up without significant slippage.

Výhodou tohoto riešenia je, že umožňuje navinutie počiatočných vrstiev návinu vytvárajúcich sa pri rozběhu vřetena bez rušivých vplyvov, nerovností a nepravidelností povrchu použitej dutinky.The advantage of this solution is that it allows winding of the initial layers of winding formed during the start of the spindle without disturbing effects, irregularities and irregularities of the surface of the used sleeve.

Na okraji hnacieho valca 1, ktorý je v styku s navíjacím vretenom 4 s dutinkou 5 je umiestnený třecí krúžok 2, například medzi unášacou přírubou 2 a telesom hnacieho valca 1.A friction ring 2, for example between the driving flange 2 and the housing of the drive roller 1, is arranged at the edge of the drive roller 1 which is in contact with the winding spindle 4 with the sleeve 5.

Zariadenie, podlá vynálezu pracuje tak, že pri rozběhu vřetena 4 je třecí krúžok 2 v priamom styku s okrajom navíjacieho vřetena 4, v ktorom zostáva po dobu vytvorénia počiatočných vrstiev návinu. Po dosiahnutí určitéj hrůbky návinu sa dostane třecí krúžok 2 mimo styk s okrajom navíjacieho vřetena 4 a ďalšie vrstvy návinu sa vytvárajú známým spůsobom, t. j. stykom návinu s pracovnou plochou hnacieho valca 1.The device according to the invention operates in such a way that, when the spindle 4 is started, the friction ring 2 is in direct contact with the edge of the winding spindle 4, in which it remains for the initial layers of winding. After a certain depth of winding has been reached, the friction ring 2 gets out of contact with the edge of the winding spindle 4 and further layers of winding are formed in a known manner, i. j. by contacting the winding with the working surface of the drive roller 1.
