Uppfinuare: H. J. van den Berge och C. G-. Schrarneyer. Inventors: H. J. van den Berge and C. G-. Schrarneyer.

Prioritet begard fain den 16 maj 194 (Nederlanderna). Priority was given on 16 May 194 (Netherlands).

Foreliggande uppfinning avser maskiner for omlindning av en ringformig kropp, sarskilt sirclana, vid vilka lindningsmaterialet dens) forradsspole dr yridbart anbragt ph en roterande ring, som omslutes ay den ringformiga kropp, som skall omlindas. The present invention relates to machines for wrapping an annular body, in particular a circle, in which the winding material its supply coil is rotatably arranged on a rotating ring which is enclosed in the annular body to be wrapped.

En m,askin av delta slag dr exempelvis den, .som beskrives i den franska patentskriften nr 670 117. Vid denna kanda maskin forses spa- len med en broms och pa den roterande ring-en anbringas aven en bladfjader, som mellan tva styrspolar trycker pa den fran spolen korn- mande traden. Harigenom Mlles trhden spand, liven om den centralt belagna delen, som skall omlindas, har rektangular tvarsektion. Det ma namnas, att det under vissa farhallanden Or onskyart att Oven kunna vrida spolen nagot tillbaka for att Ler avlinda en viss langd av den redan upplindade traden. Det har foreslagits att i sa fall forse spolen med en urfjatler. Enligt uppfinningen utfores en lindningsmaskin ay det angivna slaget ph sa salt, att, trots att pa spolen kontinuerligt utayas ett vridningsmoment i upplindningsriktningn, spolen kan utfora ett godtyckligt start antal omvridningar i avlindningsriktningen. Det namnda utforandet med en urfjader skulle joke kunna anvandas far delta andamal, ty derma fjader skulle endast tillata ett begran- sat antal omvridningar och dessutom Minna ett yariabelt vridningsmoment, sO all vid tom spole en tuna lindningstrad skulle spannas far hart. Nagon pa traden vilande bladfjader erfordras icke yid utforande enligt uppfinning- en. En fast konstant spanning underhalles standigt i traden och darigenom Or anordningen sarskilt lamplig for lindning av en lindningskarna med tuna trOd, vilken karna joke Or uppstalld exakt centralt, sa att yid varje omvridning spolen Oven maste lopa tillbaka en viss stracka. A machine of the delta type, for example, described in French Pat. No. 670,117. In this known machine the spool is provided with a brake and a leaf spring is also applied to the rotating ring, which presses between two guide spools. on the barbed wire from the coil. Through Mlles trhden spand, the waist around the centrally located part, which is to be wrapped, has a rectangular cross section. It must be mentioned that under certain conditions it is uncommon for Oven to be able to turn the spool slightly backwards in order for Ler to unwind a certain length of the already wound up thread. In that case, it has been suggested to provide the coil with a primer. According to the invention, a winding machine of the specified type is made so salty that, although a torque is continuously applied to the spool in the winding direction, the spool can perform an arbitrary starting number of turns in the winding direction. The said design with a primer spring could joke be used for delta andamal, for this spring would only allow a limited number of turns and also Minna a yariable torque, so all at empty coil a thin winding wire would be stretched far hart. No leaf spring resting on the wire is required in the embodiment of the invention. A fixed constant voltage is constantly maintained in the thread and thereby the device is particularly suitable for winding a winding core with thin wire, which the core joke Or is set up exactly centrally, so that each rotation of the coil above must run back a certain distance.

Uppfinningen kan utfOras ph olika satt. Vid ett utforande anvandes en omkring spolens axel vridbar och med spolen genom friktion kopplad kropp. Det skulle vara tankbart alt belasta den namnda kroppen med ett i det narmaste konstant fjadermoment och vid ra relse i avlindningsriktningen slutligen lista den stota snot ett fast anslag. Spanningen i trirden .skulle cla stiga stotyis far att oyervinna frik- tionsmomentet. Enligt uppfinningen utfOres emellertid anordningen ph sadant satt, att en sadan .stat undvikes, i det fjadermomentet un- der .avlindningsfasen stiger sa smaningom, tills del overstiger friktionsmomentet. Fran detta ogonblick Riper spolen ensam vidare, tills den kastar om sin vridningsriktning och medtages tillbaka av Irroppen. The invention can be practiced in various ways. In one embodiment, a body rotatable about the axis of the coil is used and coupled to the coil by friction. It would be conceivable to load the said body with an almost constant spring moment and, when moving in the unwinding direction, to finally list the stubborn snot a fixed stop. The tension in the trirene .could cla stotyis father to oyervinn the moment of friction. According to the invention, however, the device is designed in such a way that such a state is avoided, in that the spring moment during the unwinding phase increases so gradually, until part exceeds the friction moment. From this moment on, the spool alone rips on, until it reverses its direction of rotation and is taken back by the Irrop.

I stallet fOr den under fjaderverkan staende kroppen kan Oven en elektromotor anvandas, som Or kopplad med spolen och utovar ett kontinuerligt vridningsmoment i upplindningsriktningen. Vid avlindningen vrides da motorns ankare mot den av faltet och sham-men utovade verkan. Instead of the body under the action of a spring, an electric motor can also be used, which is coupled to the coil and exerts a continuous torque in the winding direction. During unwinding, the motor anchor is then turned towards the effect exerted by the field and the sham.

Vid ett tredje utforande Or spolen yid ring-ens rotation kontinuerligt i beraring med ett i derma omyridning joke deltagan.de snare, som lamnar det erforderliga vridningsmomentet i upplindningsriktningen. In a third embodiment, the rotation of the coil yid the ring is continuously in contact with a snare involved in this rewinding, which leaves the required torque in the winding direction.

Friktionen mellan delta snOre och spolen Or mycket konstant Over spolens hela bana, varigenom stotar i lindningstraden undvikas. The friction between the delta coil and the coil Or is very constant over the entire path of the coil, thereby avoiding bumps in the winding wire.

Deana friktions storlek Or reglerbar genom att andra drauspanningen i snaret. Dessutom erfordrar dettl snore mycket litet utrymme, varigenom det far forrildsspolen .disponibla rummet i innerprofilen hos den kropp, som skall lindas, praktiskt taget joke- inskrankes. Deana friction size Or adjustable by second draus tension in the snare. In addition, this cord requires very little space, whereby the space available in the inner profile of the body to be wound is practically joke-restricted.

Utforandet med sniiret fortydligas i det 101- jande med hjalp av bifogade ritning. Fig. 1 visor en vy fran framsidan ay ett sadant utforande och fig. 2 och 3 visa nagra detaljer. The design with the sniiret is clarified in the 101st with the help of the attached drawing. Fig. 1 shows a view from the front of such an embodiment and Figs. 2 and 3 show some details.

Lindningsmaskinen bestar av en yertikalt anordnad grundplatta 10, yid vilken medelst .ett antal bultar 13 Or fast en cirkelformig skiva 14. Denna cirkelformiga skivas omkrets Or sh utformad, att mellan derma skiva och grundplattan 10 bland ,annat bildas en cirkular ranna med rektangulart tvarsnitt 15. I denna ranna Or rorligt anbragt en till ett ring-segment 16 horande flans. Ringsegmentet 16 tjanstgOr som rorligt barorgan far en fOrradsspole 17, ph vilken den had, som skall lindas, 2— — är anbragt. Denna forradsspole ár monterad pa en axel 18, som är fast vid segmentet 16. The winding machine consists of a vertically arranged base plate 10, which by means of a number of bolts 13 is fixed to a circular disc 14. The circumference of this circular disc is shaped so that between this disc and the base plate 10, among other things, a circular groove with a rectangular cross section 15 is formed. A flange belonging to a ring segment 16 is arranged in this groove. The ring segment 16 serves as a movable bar member for a supply coil 17, the hose of which to be wound is placed. This supply coil is mounted on a shaft 18, which is fixed to the segment 16.

I grundplattan 10 och den yid denna fasta ,cirkelformiga skivan 14 är anbragt en rektangular urtagning 11, som stracker sig mat fran grundplattans omkrets, och vars dimensioner am tillrackligt stora for att den storsta kropp 12, som skall lindas, skall kunna anbringas i namnda urtagning. Ringsegmentet 16 stracker sig utover en vinkel storre an 180', varfor segmentet visserligen ar rorligt i rannan 15 men dock oavtagbart inneslutet i denna. Vinkeln ar mindre an 360°, varfor mellan detta segments bada andar 19 finnes en oppning av ungefar samma storlek som ovannamnda urtagning 11. Denna oppning tjanar till den i for handen varande fall helt slutna, ringformiga kroppens 12 infOrande i ringsegmentet 16 pa ett sadant salt, att den av den ringformiga kroppen 12 omslutna ytan skiires vid segmentets vridning kring medelpunkten. A rectangular recess 11 is arranged in the base plate 10 and the fixed plate 14 thereon, which rectangle extends food from the circumference of the base plate, and whose dimensions are sufficiently large for the largest body 12 to be wound to be fitted in said recess. . The ring segment 16 extends beyond an angle greater than 180 ', so that the segment is admittedly movable in the rim 15 but nevertheless inextricably enclosed therein. The angle is less than 360 °, so that between the two ends 19 of this segment there is an opening of approximately the same size as the above-mentioned recess 11. This opening serves for the presently completely closed, annular body 12 insertion into the ring segment 16 on such a salt. , that the surface enclosed by the annular body 12 is formed by the rotation of the segment about the center point.

Namnda ringsegment 16 sates i iiirelse me-deist tvenne med varandra sammankopplade kugghjul 21 och 22, som stá i ingrepp med en ringsegmentets oinkrets anbragt kuggkrans 20. De hada kugghjulen 21 och 22 aro anbragta pa ett storre avstand fran varandra an det kortaste avstandet mellan segmentets andytor 19, sã att det ena av kugghjulen 21 och 22 all-lid star i ingrepp med ringsegmentet och kan paverka detta. Said ring segment 16 is set in motion by means of two interconnected gears 21 and 22, which are in engagement with a ring ring 20 arranged in a circle of the ring segment. The had gears 21 and 22 are arranged at a greater distance from each other than the shortest distance between the segments. and surfaces 19, so that one of the gears 21 and 22 all-lid engages the ring segment and can affect it.

Ringsegmentet 16 uppbar utom den redan tidigare namnda forradsspolen 17 ytterligare en pa en likaledes vid segmentet 16 fast axel 24 anbragt styrrulle 23 for lindningstraden. Om ringsegmentet forsattes i rotation medelst de bada kugghjulen 21 och 22, sa. komma sa- fOrradsspolen 17 som aven styrrullen 23 att stegvis rora sig genom det av den ringformiga kroppen 12, som skall lindas, omslutna rummet och deras bana sluter sig &ter utanfor denna kropp. Lindningstraden 25, vars ande i forvag fasts vid en punkt pa kroppen 12, slas genom derma rorelse omkring namnda kropp i ett genom dennas cylinderaxel lagt plan. Den ringformiga kroppen 12 uppbares av en kring en axel 27 svangbar_firm 26, vilken axel är parallell med eller sammanfaller med sagda kropps axel. Denna arm paverkas under lindningsfOrloppet regelbundet medelst ett kugghjul 28 samt en med detta i ingrepp staende kuggstang 29, varigenom tra.den 25 slutligen skruvlinjeformigt lindas omkring kroppen 12. The ring segment 16 carried, in addition to the already mentioned storage coil 17, a further guide roller 23 for the winding wire, also fixedly attached to the segment 16, mounted on the segment 16. If the ring segment was continued in rotation by means of both gears 21 and 22, said. the sapphire coil 17 as well as the guide roller 23 will gradually move through the space enclosed by the annular body 12 to be wound and their path closes outside this body. The winding wire 25, the spirit of which is fixed in advance at a point on the body 12, is struck by this movement about said body in a plane laid through its cylinder axis. The annular body 12 is supported by a pivot 26 pivoting about an axis 27, which axis is parallel to or coincides with the axis of said body. This arm is regularly actuated during the winding process by means of a gear 28 and a gear 29 engaged therewith, whereby the wire 25 is finally helically wound around the body 12.

Under ringsegmentets 16 vridningsrorelse forstoras och forminskas stegvis avstandet mellan kroppens 12 lindade genomsnitt och styrrullen 23 reap. forradsspoIen 17. Genom denna relativa rOrelse hos forradsspolen resp. styrrullen och kroppen, som skall lindas, maste en langd lindningstrad stegvis avlindas och sedan en, om ocksa nagot mindre langd Ater upplindas. For detta andamal ar en sfirskild drivanordning for forradsspolen 17 erforderBg; denna drivanordning maste i varje fall vara verksana under tradens upplindning. For enkelhetens skull har emellertid valts en upplindningsanordning, som stadse stravar att astadkomina forradsspolens 17 upplindning, men som dock genom en friktionskoppling mojliggor spolens avlindning, enar ett snore 31 ãr anbragt i ett relativt ringsegmentet 16 koncentriskt spar 301 den cirkelformiga ski-van 14. Namnda snores ena dude ãr fast vid en fixpunkt 32 pa grundplattan 10, och detsammas andra uncle ãr paverkad av en i langdriktningen installbar dragfjader 33. Detta snore Or dessutom styrt genom ett i forradsspolen 17 anbragt spar 34 och ett 1 styrrullen 23 anbragt spar 35. Vid ringsegmentets 16 och de vid detta fasta forradsspolens 17 och styrruilens 23 rorelse wider det relativt segmentet stillastaende snoret fOrradsspolen och styrrullen i en bestamd riktning; d. v. s., dh ringsegmentet vrides medsols, vridas spolen och styrrullen motsols. Lindningstraden 25 är upplindad pa. fOnadsspolen 17 pa. ,ett sadant satt, att densamma upplindas pa, forradsspolen vid ringsegmentets 16 widning i den antydda riktningen. Under ,ett halvt vary, varvid traden skull .avlindas, glider snoret 31 i sparen 34 on 35 i forradsspolen reap. styrrullen. Sa snart traden emellertid har uppnatt sin storsta langd och forradsspolen ater rOr sig I riktning mot kroppen 12, upplindas traden ater omedelbart, utan att traden darvid slaknar. During the rotational movement of the ring segment 16, the distance between the wound average of the body 12 and the guide roller 23 reap is gradually increased and decreased. the storage coil 17. Through this relative movement of the storage coil resp. the guide roller and the body to be wound, a length of winding line must be unwinded step by step and then one, if also slightly lesser length, must be wound up again. For this purpose, a separate drive device for the supply coil 17 requires Bg; this drive must in any case be effective during the winding of the trade. For the sake of simplicity, however, a winding device has been chosen which constantly strives to effect the winding of the storage spool 17, but which nevertheless allows the spool to unwind by a friction coupling, a cord 31 is arranged in a concentric groove 301 of the circular disc 14 one cord is attached to a fixed point 32 on the base plate 10, and the same uncle is actuated by a longitudinally installable tension spring 33. This cord is also guided by a groove 34 provided in the supply spool 17 and a groove 35 arranged in the guide roller 23. the ring segment of the ring segment 16 and the movement of the fixed spool 17 and the guide rail 23 fixed thereto wider the stationary spool of the spool and the guide roller stationary relative to the segment in a certain direction; i.e., ie the ring segment is turned clockwise, the spool and the guide roller are turned counterclockwise. The winding wire 25 is wound on. fOnadsspolen 17 pa. , in such a way that it is wound on the supply coil at the winding of the ring segment 16 in the indicated direction. During a half turn, during which the thread is to be unwound, the cord 31 slides in the groove 34 and 35 in the supply spool reap. the guide roller. However, as soon as the thread has reached its greatest length and the supply spool moves again in the direction of the body 12, the thread is rewound immediately, without the thread slackening.

Den kraft, varmed traden 25 skall upplindas, beror av dennas styrka och styvhet. Denna kraft Or reglerbar genom andring av fjaderns 33 spanning, varigenom lindningsmaskinen kan gams anvandbar f5r olika tradsorter. Nar snoret lake ligger i de bada rullarnas spar 34 och 35, vilar det i det cirkulara sparet 30, som Or anordnat i den cirkelformiga skivan 14. I andamal att undvika ett avbrytande av driften ligger snoret 31 mer an ett halt vary i sparet 30. Detta har darfor, i likhet med sparen 34 och 35, en nagot storre bredd an snorets 31 dubbla tjocklek. Genom att indranka detta snore med olja, kan friktionen mellan snoret och rullarna 17 och 23 gOras myc- ket jamn, varfor trad av tjocklek kun- na lindas med denna lindningsmaskin. The force with which the thread 25 is to be wound depends on its strength and stiffness. This force is adjustable by changing the tension of the spring 33, whereby the winding machine can be used for different types of wire. When the cord lake lies in the grooves 34 and 35 of the two rollers, it rests in the circular groove 30, which Or is arranged in the circular disc 14. In order to avoid an interruption of the operation, the cord 31 lies more than a content vary in the groove 30. This, therefore, like the grooves 34 and 35, has a slightly larger width than the double thickness of the cord 31. By soaking this cord with oil, the friction between the cord and the rollers 17 and 23 can be made very even, so that threads of thickness can be wound with this winding machine.

Forradsspolen har en viss med trad lindad bredd, sO att den punkt, vid vilken traden lanmar spolen, forflyttas i den man, som spolen ytterligare avlindas. En sadan fOrskjutning av &Aden skulle ha till f8ljd, att den punkt lake ar fixerad, vid vilken denna trad uppnar det tvarsnitt, som skall lindas. Styrrullen 23, vars omkrets Or f8rsedd med en Vformig profil, Or darair anordnad pa. ringsegmentet 16 i andamal att a.stadkomma en. riktig styrning av traden. Traden, som avlindas, forblir alltid liggande i V-ets spets, sak samma Iran vilken punkt pa. forradsspolen traden kommer. Styrrullen 23 paverkas likaledes nv snoret 31 i andamal att hindra traden Iran att upptaga de accelerationskrafter, vilka ound- — —3 vikligen upptrada vid dndringen av denna rulles rotationsriktning vid overgangen frfin den stegvisa upplindningen till den stegvisa avlindningen av traden. Det ãr ocksa mojligt att drive denna styrrulle 23 medelst en sarskild bdranordning, t. ex. en barare, som är anordnad koncentriskt relativt den a ritningen visade, innanfor eller utanfor denna. The supply spool has a certain width wound with wire, so that the point at which the wire lands the spool is moved in the man, as the spool is further unwound. Such a displacement of & Aden would result in the point at which the lake is fixed reaching the cross-section to be wound. The guide roller 23, the circumference of which is provided with a V-shaped profile, is arranged on. ring segment 16 in the spirit of a. proper control of the trade. The trade, which is unwound, always remains at the forefront of the West, no matter what point Iran makes. the supply coil trade comes. The guide roller 23 is likewise actuated by the cord 31 in order to prevent the trade Iran from absorbing the accelerating forces which inevitably occur in changing the direction of rotation of this roller at the transition from the stepwise winding to the stepwise unwinding of the trade. It is also possible to drive this guide roller 23 by means of a special conveyor device, e.g. a bar, which is arranged concentrically relative to that shown in the drawing, inside or outside it.

I detta fall kan ndmnda rulles ovan anforda drivande antingen helt och hallet undvaras eller astadkommas medelst sarskilda anordningar. In this case, the above-mentioned rollers can provide driving either completely and the hall is dispensed with or provided by means of special devices.
