Abstract

The clamping mechanism for elastic clamping of tubes can be utilized in the production of synthetic fibres in knots where the change of tubes and sheaves occurs and generally in textile industry and it is intended for devices for application of tubes, to advantage for manipulators. The elastic clamping is enabled by three elastic segments, which are mounted inside the bearing guide roller, which is located in the shifting sleeve. The sleeve is equipped on the inner side in the central part at least with two grooves with elastic securing elements, which are equipped on the marginal part with rubber bases via a recess in the shifting sleeve while the rubber bases fit into the recess, which is placed on the outer side in the longitudinal axis of the elastic pressing segment.<IMAGE>

Description

Vynález rieši upinacíe ústrojenstvo prs pružné uchytenie dutiniek na zariadeni pra automatické naaúvania dutiniek ns trne navijácích etrojov textilných materiálov. ktoré zaistuje jej otáčanie/ pričom umožňuje jej čiastočný radiálny resp. krížny pohyb·The invention provides for a breast clamping device for resiliently fastening the tubes on a device for automatically pulling the tubes on the mandrel of the winches of textile materials. which ensures its rotation / allowing its partial radial resp. cross motion ·

Známe eú automatické zariadenia»' ktoré pracujú na principe priamočiareho pohybu pri naeúvani dutiniek. Napr. aa využívajú apoločne riadenó zachytávače, z ktorých každý zachytává len jednu dutinku tak/ že po odobrati a odloženi plnaj dutinky na odkladacia zariadenie ea prázdné dutinky privedú do dráhy pohybu zachytávačov a nasadia 3a na vretená,· pričom na odoberanie a naeúvanie dutiniek eú použité tia istó zachytávače. Ručně snimanie a ukladanie dutiniek odstraňuje riešenie podlá OS AO 188 035. Pri naeúvani dutiniek automatickými zariadeniami je důležité centrovanie podávacieho mie3ta na manipulátore e odoberajúcin mieetom, akým je vřeteno navijacieho etroja. U známých riešeni musi ief o přesné a súosé navádzanie dutinky, ktoré nedovoluje prisposobenie aa v případe nepřesnosti polohy třňa navijacieho stroja. Uchytávanie a pritláčanie dutiniek na čelných plochách sposobuje ich poškodzovanie a poruchy jednak na manipulátora, ale najmS v navijacom procese.We have known automatic devices »which operate on the principle of rectilinear movement when pulling the tubes. E.g. aa employ an application-controlled gripper, each gripping only one tube, so that after removal and removal of the full tube to the storage device ea, the empty tubes are brought into the travel path of the grippers and fitted to the spindles; catchers. Manually sensing and storing the cores removes the solution according to OS AO 188 035. When moving the cores by automatic devices, it is important to center the feeding spout on the manipulator with a remover such as the spindle of the winding machine. In the known solutions, it is necessary to guide the sleeve precisely and coaxially, which does not allow adjustment and even in the case of inaccurate position of the mandrel of the winding machine. The gripping and squeezing of the cavities on the front surfaces causes damage and defects on the manipulator, but especially in the winding process.

Uvedená nedostatky rieši upínacie ústrojenstvo pre pružné uchytenie dutiniek,· podstatou ktoróho Ja vytvorenie vhodnej tolerancie medzi vonkajším priemerom dutinky a vnútorným priemerom nosného vodiaceho valca a to tak, že vo vnútri nosného vodiaceho valca,’ uloženého v posuvnej objímke aú umiestnené aspoň tri pružné přítlačné segmenty opatřené na vnútornej straně v strednej časti najmenej dvomi drážkami s pružnými zaistovacími prvkami,· na krajnej časti opatřenými pryžovými pžftkami,· cez vybratie v posuvnej objímke zapadajúcimi do vyhlbenia,umiestneného na vonkajšej straně v pozdlžnej osi pružného přítlačného segmentu.These drawbacks are solved by a clamping device for resiliently gripping the sleeves by providing a suitable tolerance between the outer diameter of the sleeve and the inner diameter of the support guide roller, such that at least three resilient pressure segments are disposed within the support guide roller. provided on the inner side in the central part with at least two grooves with resilient securing elements, · on the outer side provided with rubber blades, · through a recess in the sliding sleeve engaging in a recess, located on the outer side in the longitudinal axis of the flexible pressure segment.

Pružný sposob uchytenia dutinky umožňuje priapoaobif sa nepřesnosti polohy trňov navíjecích etrojov v rámci tolerancie danej rozdielom medzi vonkajším priemerom dutinky a vnútorným priemerom nosného vodiaceho valca, pružnostou pružných přítlačných segmentov a zároveň rozdiel a umožňuje využitie uvedeného zariadenia i pra dutinky, ktoré aú výrobcem dodávané s vžfčšou tolaranciou vonkajšieho priemeru dutinky.The resilient sleeve gripping method allows the inaccuracies of the mandrel position of the winding machines to be tolerated within the tolerance given by the difference between the outer diameter of the sleeve and the inner diameter of the bearing guide roller, the elasticity of the elastic pressure segments. by the diameter of the outer diameter of the tube.

Příklad pružného uchytenia dutinky v nosnom vodiacom válci/ napr. manipulátora je znázorněný na obrázku.An example of resilient attachment of a sleeve in a support guide roller / e.g. The manipulator is shown in the figure.

V posuvnej objímko 105 s vybratim 107 je uložený nosný vodiaci válec 104, vo vnútri ktorého sú umiestnené aspoň tri pružné přítlačné segmenty 101, opatřené na vnútornej strana v strednej časti najmenej dvomi drážkami 101*8 pružnými zaisfovacími prvkami přítlačných segmentov 10S na fcrejnsj časti opatřených pryžovými pStkami 102, zapadajúcimi do zahlbenia umiestneného na vonkajšej straně v pozdlžnej oai pružného segmentu.A sliding sleeve 105 with a recess 107 accommodates a support guide roller 104, inside which at least three resilient pressure segments 101 are provided, provided on the inner side with at least two grooves 101 * 8 with resilient securing elements of the pressure segments 10S on the rubber-coated part. With the pawls 102 engaging a recess located on the outside of the longitudinal elastic segment.

Pri nasunuti dutinky 200 do nosného vodiaceho valca 104 priamočiarym pohybom zabezpečeným napr. pneumatickým pohonem ja daná do činnosti v axiálnom smere posuvná objímka 105. ktorá cez guličky 103 posúva v radiálnom 6mere pružné přítlačné segmenty 101, rozložené pod úhlom 120°. Možnoaf prisposobenia sa polohe třňa navijacieho stroja js vyjádřená tolaranciou a medzi vonkajším priemerom dutinky 200 a vnútorným priemerom nosného vodiaceho valca-104« Stabilitu pružných přítlačných segmentov 101 ako aj ich polohu v rozovratom stave zaistuje prvok 106/ napr. rozpiaracie krúžky. Prvok 106 je vedený v drážkách 101* pružných přítlačných segmentov 101 a vodiaceho valca 104. Po nasunutí dutinky 200 na trň navijacieho stroja sa prevedie obrátený cyklus vzhladom k uchyteniu dutiniek/ čim sa dutinka uvolni. K samotnému uvoínaniti priapiava napr. rozpinací krúžok 406/ ktorý mechanicky evojou pružnosfoupo uvolnění guličiek 103 roztláča pružné přítlačné segmenty 101.Upon insertion of the sleeve 200 into the support guide roller 104 by a linear motion provided e.g. By means of a pneumatic drive, a sliding sleeve 105 is actuated in the axial direction which, via balls 103, displaces the elastic pressure segments 101 spaced at 120 [deg.] in a radial 6 direction. Possibility of adapting to the mandrel position of the winding machine is expressed by tolarancy, and between the outer diameter of the sleeve 200 and the inner diameter of the support guide roller-104. rip rings. The element 106 is guided in the grooves 101 * of the elastic pressure segments 101 and the guide roller 104. After sliding the sleeve 200 onto the mandrel of the winding machine, an inverted cycle is performed with respect to the sleeve gripping / loosening the sleeve. The actual release priapiava eg. an expanding ring 406 which mechanically evokes the elastic / loosening of the balls 103 to squeeze the elastic pressure segments 101.
