(54) i aksial retning fjedrende sammentrykkelig spole.(54) in the axial direction resilient compressible coil.
Opfindelsen angår en cylindrisk eller konisk, i aksial retning fjedrende sammentrykkelig spole af den i krav l's indledning angivne art.The invention relates to a cylindrical or conical, axially resilient compressible coil of the kind set forth in the preamble of claim 1.
De hidtil kendte, i aksial retning fjedrende sammentrykkelige spoler, fortrinsvis til brug ved vådbehandling af garnvindsler, f.eks. ved farvning af disse, er i fabrikationsmæssig og navnlig i montageteknisk henseende belastet med mange ulemper, idet de er for dyre og i øvrigt også hyppigt giver anledning til forstyrrelser. Deres bøjningsstabilitet i akseretningen er ringe, således at der let indtræder beskadigelser af garnet.The previously known, axially resilient compressible coils, preferably for use in wet treatment of yarn winding, e.g. in dyeing these, many manufacturing disadvantages, in the fabrication and especially in the mounting technique, are too expensive and, moreover, also frequently cause disturbances. Their bending stability in the axis direction is poor, so that damage to the yarn easily occurs.
Den foreliggende opfindelse har til formål at angive en sådan udformning af en spole af den ovennævnte art, at der ved den enklest mulige konstruktion, som eventuelt uden videre endog kan fremstilles i ét stykke, trods en lettere og i forhold til de tidligere kendte udformninger større sammentrykkelighed i aksial retning, opnås en stor bøjningsstabilitet i akseretningen.The present invention has for its object to provide such a design of a coil of the above-mentioned type that, in the simplest possible construction, which can possibly even be manufactured in one piece, in spite of a lighter and in comparison with the prior art designs, axial compressibility, a large bending stability is obtained in the axial direction.
Dette opnås ifølge opfindelsen ved, at spolen er udformet som angivet i krav l's kendetegnende del.This is achieved according to the invention in that the coil is designed as defined in the characterizing part of claim 1.
2 14320Λ2 14320Λ
Som følge af denne udformning er der tilvejebragt en betydelig forenklet konstruktion af en spole af ovennævnte art. F.eks. ved fremstilling ved formstof-sprøjtestøbningsmetoden kan der opnås en konstruktion, som består af et eneste stykke, som heller ikke længere behøver efterbearbejdning. Spolen kan fremstilles til så lav pris, at den kan anvendes som eengangsspole. Dette medfører frem for alt den fordel, at spolen efter farvningen kan forblive i garnvindslet og efter bearbejdning af garnet kastes bort. Ribbernes form af flade lameller, hvis breddeudstrækning er hovedsagelig vinkelret på spolens kappeflade, giver spolen en stor bøjningsstivhed. Man har endvidere fundet, at der alt efter ribbernes form kan opnås en betydelig større sammentrykkelighed, end der kunne opnås ved de hidtil kendte konstruktioner. Ved valg af egnede materialer kan det opnås, at vindselbæreren efter varmfarvningen ikke igen strækker sig fuldstændigt ud i sin fulde længde, hvilket er fordelagtigt for afspolingen.As a result of this design, a considerably simplified construction of a coil of the above kind is provided. Eg. by fabrication by the plastic injection molding method, a structure can be obtained which consists of a single piece which also no longer needs finishing. The coil can be manufactured at such a low cost that it can be used as a single coil. Above all, this has the advantage that after the dyeing, the bobbin can remain in the yarn roll and after processing the yarn is discarded. The shape of the ribs of flat slats, the width of which is mainly perpendicular to the coil surface of the coil, gives the coil a high bending stiffness. Furthermore, it has been found that, depending on the shape of the ribs, a considerably greater compressibility can be obtained than could be achieved with the known structures. By selecting suitable materials, it can be achieved that, after the heat-staining, the winding carrier does not fully extend to its full length, which is advantageous for the rewinding.
Det kan også, alt efter egenskaberne af det garn, som danner vindselet, være fordelagtigt, at de i sig selv ringformigt lukkede ribber ifølge opfindelsen i forbindelse med delafsnit danner bøjningszonen. Derved opnås en forholdsvis høj sammentrykningsmodstand af spolen og en god anlægsflade for garnet. Hvis der ønskes en mindre sammentrykningsmodstand, kan ribberne have S-form.It may also be advantageous, depending on the characteristics of the yarn forming the winding, that the annularly closed ribs according to the invention form part of the bending zone in connection with sub-sections. This results in a relatively high compression resistance of the bobbin and a good contact surface for the yarn. If a smaller compression resistance is desired, the ribs may be S-shaped.
Hvis ribberne ifølge opfindelsen er udformet som omtrent U-formige bøjler, som er forbundet med de bort fra bøjleenderne vendende afsnit af vindselbæreringen, opnås en middelhøj sammentrykningsmodstand. Man kan således ved passende valg af ribbernes form afpasse spolens sammentrykningsmodstand efter den garnkvalitet, som skal forarbejdes.If the ribs of the invention are designed as approximately U-shaped shackles which are connected to the portions of the winding ends facing away from the shackle ends, a medium-high compression resistance is obtained. Thus, by appropriate choice of the shape of the ribs, the compression resistance of the bobbin can be adjusted to the yarn quality to be processed.
Ved fremstillingen af en sådan vindselbærer i en konstruktion af et enkelt stykke, f.eks. ved formstofsprøjtestøbningsmetoden, kan en maksimal bøjningsstivhed ifølge opfindelsen opnås ved, at midterdelene af de i samme tværsnitsplan anbragte ribber på den i eet stykke af formstof sprøjtestøbte spole er forbundet med hinanden ved hjælp af en i eet stykke med ribberne udformet stabiliseringsring. Ved ak-sial sammentrykning af spolen påtvinger denne stabiliseringsring de dermed forbundne ribber samme udbøjning i spolens omkredsretning og dermed en ensartet sammentrykning.In the manufacture of such a windscreen carrier in a single-piece construction, e.g. by the injection molding method, a maximum bending stiffness according to the invention can be obtained by connecting the middle parts of the ribs arranged in the same cross-sectional plane to the one of the plastic injection molded coils by means of a stabilizing ring formed in one piece with the ribs. By axial compression of the coil, this stabilizing ring forces the associated ribs to have the same deflection in the circumferential direction of the coil and thus a uniform compression.
En relativt ringe belastning af stabiliseringsringen, navnlig en relativt ringe tværbelastning af denne, opnås på fordelagtig måde ifølge opfindelsen ved, at stabiliseringsringene ligger tilbagetrukket i forhold til kappefladen, og at de har et i forhold til enderingene og mellemringene tyndere tværsnit. Denne foranstaltning er ikke blot fordelagtig i brugsteknisk henseende, men bevirker også, at materialeforbruget kun forøges meget lidt.A relatively low load of the stabilizer ring, in particular a relatively low cross-load thereof, is advantageously obtained according to the invention in that the stabilizer rings are retracted relative to the casing surface and have a thinner cross-section relative to the end rings and intermediate rings. This measure is not only advantageous in terms of technical use, but also causes the material consumption to increase very little.
En i teknologisk henseende fordelagtig konstruktionsmåde består i denne forbindelse ifølge opfindelsen i, at stabiliseringsringenes inderflade flugter med inderfladen af ende- og mellemringene og inderfladen af ribberne. Derved kan der ved sprøjtestøbningen af spolen anvendes en glat dorn som støbekerne.A technologically advantageous design method in this connection according to the invention consists in the fact that the inner surface of the stabilizing rings aligns with the inner surface of the end and middle rings and the inner surface of the ribs. In this way, a smooth mandrel like the casters can be used in the injection molding of the coil.
En i teknologisk henseende gunstig udformning består ifølge opfindelsen 3 1 4 3 2 Ο Λ endelig i, at de brede flader af ved siden af hinanden beliggende, i samne tværsnitsplan anbragte ribber skiftevis er rettet radialt og hældet i forhold til radialretningen. Derved kan flere ved siden af hinanden liggende ribber formes med en enkelt, radialt udtrækkelig, ydre støbeformdel.A technologically advantageous design according to the invention 3 1 4 3 2 Λ Λ finally consists in that the wide surfaces of adjacent ribs arranged in the same cross-sectional plane are alternately radially directed and inclined in relation to the radial direction. Thereby, several adjacent ribs can be formed with a single, radially extendable outer mold part.
Spolen ifølge opfindelsen er nærmere beskrevet i det følgende under henvisning til tegningen, på hvilken fig. 1 og 2 viser en første udførelsesform for spolen, set fra siden og fra oven, fig. 3 og 4 en anden udførelsesform, set fra siden og fra oven, fig. 5 og 6 en tredje udførelsesform, set fra siden og fra oven, fig. 7 og 8 en fjerde udførelsesform, set fra siden og fra oven, fig. 9 og 10 en femte udførelsesform, set fra siden og fra oven, fig. 11 og 12 en sjette udførelsesform, set fra siden og fra oven, fig. 13 en sidste udførelsesform, set fra siden, fig. 14 samme i aksial sammentrykket stilling, set fra siden, fig. 15 et snit efter linjen XV-XV på fig. 13, og fig. 16 et snit efter linjen XVI-XVI på fig. 13.The coil according to the invention is described in more detail below with reference to the drawing, in which FIG. 1 and 2 show a first embodiment of the coil, seen from the side and from above; FIG. 3 and 4 show another side view from above; FIG. 5 and 6 show a third side view from above; FIG. 7 and 8 show a fourth side view from above; FIG. 9 and 10 show a fifth embodiment, seen from the side and from above; 11 and 12 are a sixth side view from above; FIG. 13 is a side view of a last embodiment; FIG. 14 is the same in axial compressed position, as seen from the side; FIG. 15 is a sectional view taken along line XV-XV of FIG. 13, and FIG. 16 is a sectional view taken along line XVI-XVI of FIG. 13th
Spolen pi fig. 1 og 2 har enderinge 1 og 2. Mellem disse forløber bæreelementer i form af elastisk bøjelige ribber 3. Disse er udformet i samme materiale som enderingene 1 og 2. De er i midterområdet støttet af en mellemring 4.The coil of FIG. 1 and 2 have end rings 1 and 2. Between these extend supporting elements in the form of elastically flexible ribs 3. These are formed in the same material as the end rings 1 and 2. They are supported in the middle region by an intermediate ring 4.
Ribberne 3 har i forhold til spolens længdeakse x-x hældede længdeafsnit 3' og 3". Mellem afsnittene 3' og 3" ligger bøjningssteder 5.The ribs 3 have inclined longitudinal sections 3 'and 3 "in relation to the longitudinal axis x-x of the coil. Between the sections 3' and 3" lie bending points 5.
Ribberne 3 er fordelt ensartet langs spolens omkreds. De af afsnittene 3' og 3" indesluttede åbningsvinkler peger i samme retning.The ribs 3 are distributed uniformly along the circumference of the coil. The opening angles of sections 3 'and 3 "point in the same direction.
De smalle flader 3''' af ribberne 3 peger udad, altså mod spolens kappeflade.The narrow surfaces 3 '' 'of the ribs 3 point outwards, ie towards the coil surface of the coil.
Ved udformningen ifølge fig. 3 og 4 er der anbragt yderligere mellemringe 4' mellem enderingene 1 og 2. Mellem hver to sådanne ved siden af hinanden beliggende ringe forløber ribberne 6. Disse består også i dette tilfælde af elastisk bøjeligt materiale. De danner mellem hver to ringe kun eet bøjningssted 7. De fra disse bøjningssteder 7 i samme retning udgående afsnit 6' og 6" danner den åbne vinkel β med hinanden. Denne vinkel peger skiftevis mellem hver to i højderetningen ved siden af hinanden beliggende ribber 6 i modsat retning.In the embodiment of FIG. 3 and 4, further intermediate rings 4 'are arranged between the end rings 1 and 2. Between the two rings adjacent to each other, the ribs 6 extend, which in this case also consists of elastic flexible material. They form between each two rings only one bending point 7. The sections 6 'and 6 "extending from these bending points 7 in the same direction form the open angle β with each other. This angle alternates between each two vertically adjacent ribs 6 in the opposite direction.
De smalle kanter 6''’ af ribberne 6 ligger i spolens kappeflade.The narrow edges 6 '' of the ribs 6 lie in the casing surface of the coil.
4 1Λ S 2 Ο Λ I udformningen pi fig. 5 og 6 er der anbragt ringformigt lukkede ribber 8, hvor bøjningsstederne i det væsentlige dannes af delafsnittene 8' og 8". Der er også i dette tilfælde anbragt flere mellemringe 4' samt enderinge 1 og 2. De mellem ringene 1 og 4' liggende ribber 8 er anbragt forsat i forhold til de derunder mellem to mellemringe 4' beliggende ribber 8. Ogsl i denne udformning ligger de smalle kanter 81 *' af ribberne 8 i spolens kappeflade.4 1Λ S 2 Ο Λ In the embodiment of FIG. 5 and 6, annularly closed ribs 8 are provided, where the bending sites are formed essentially by the sub-sections 8 'and 8 ". ribs 8 are disposed offset relative to the ribs 8 located therebetween between two intermediate rings 4 '. Also, in this embodiment, the narrow edges 81 *' of the ribs 8 lie in the casing surface of the spool.
I udformningen ifølge fig. 7 og 8 er ribberne 9 udformet S-formet. De omtrent parallelt med hinanden forløbende endeafsnit af disse S-formige ribber sidder pi mellemringe 4', henholdsvis enderinge 1 og 2. De i forhold til spolens længdeakse x-x skråt forløbende delafsnit 9' og 9" bevirker en elastisk bøjning af ribben 9. De smalle kanter 9*'* af ribberne er vendt mod spolens kappeflade.In the embodiment of FIG. 7 and 8, the ribs 9 are S-shaped. The approximately parallel end portions of these S-shaped ribs are located in intermediate rings 4 'and end rings 1 and 2. The inclined portion sections 9' and 9 ", respectively, of the coil longitudinal axis 9 cause elastic bending of the ribs 9. The narrow edges 9 * '* of the ribs are facing the coil surface of the coil.
I udformningen pi fig. 9 og 10 består ribberne 10 af omtrent U-formige bøjler. De i forhold til vindselbærerens længdeakse x-x skråt forløbende delafsnit 10' og 10" tilvejebringer den elastiske bøjelighed. Fra bøjleenderne udgår der udadrettede afsnit 11 og 12. Disse sidder ved mellemringene 4', henholdsvis ved enderingen 1 og 2. Afsnittene 11 og 12 samt de umiddelbart tilgrænsende bøjleender 13 og 14 er af større materialetykkelse, således at der i afsnittene 10' og 10" foreligger foretrukne, af den ringere materialetykkelse betingede bøjningstværsnit. Herved undgås, at garnlag, frem for alt i begyndelseszonen for spolens sammentrykning, kan nå ind i spalten 23 og der blive klemt inde. De smalle kanter 10''' af de bøjleformede ribber 10 ligger i spolens kappeflade.In the embodiment of FIG. 9 and 10, the ribs 10 consist of approximately U-shaped shackles. The elastic sections 10 'and 10 "which extend in relation to the longitudinal axis xx of the windscreen xx provide the elastic flexibility. Outwardly extending sections 11 and 12. are provided at the intermediate rings 4', respectively at the end rings 1 and 2. The sections 11 and 12 and the adjacent bend ends 13 and 14 are of greater material thickness, so that bending cross sections conditional on the inferior material thickness exist in sections 10 'and 10 ". This prevents yarn layers, especially in the initial zone of coil compression, from reaching the slot 23 and being squeezed inside. The narrow edges 10 '' 'of the hoop-shaped ribs 10 lie in the coil surface of the coil.
I udformningen på fig. 11 og 12 er materialeafsnittene 11' og 12" gjort bredere, hvorved praktisk taget alle bøjleender 13' og 14' er stift forbundet med mellemringene 4', henholdsvis enderingene 1 og 2.In the embodiment of FIG. 11 and 12, the material sections 11 'and 12 "are made wider, whereby practically all bracket ends 13' and 14 'are rigidly connected to the intermediate rings 4' and the end rings 1 and 2, respectively.
Ved udførelsen ifølge fig. 13-16, ved hvilken hele spolen er fremstillet ved formstofsprøjtestøbningsmetoden af et enkelt stykke egnet materiale, er ribberne 15 udformet med V-form. Enderne af V-grenene 15' og 15" er over lette materialefortykkelser 16 fastgjort til ringene 1, 2 og 4.In the embodiment according to FIG. 13-16, in which the entire coil is made by the single-injection molding method of a single piece of suitable material, the ribs 15 are formed with a V-shape. The ends of the V-branches 15 'and 15 "are attached over light material thicknesses 16 to the rings 1, 2 and 4.
Topzonerne 17 af alle de i samme tværsnitsplan anbragte ribber 15 er indbyrdes forbundet ved hjælp af en i ét stykke dermed udformet stabiliseringsring 18.The top zones 17 of all the ribs 15 arranged in the same cross-sectional plane are interconnected by means of a one-piece stabilizing ring 18 formed therewith.
Inderfladen 18' af stabiliseringsringen 18 flugter med inderfladen 19 af ribberne 15 og med inderfladerne 20 af ringene 1, 2 og 4.The inner surface 18 'of the stabilizing ring 18 aligns with the inner surface 19 of the ribs 15 and with the inner surfaces 20 of the rings 1, 2 and 4.
Hver stabiliseringsring 18 har i forhold til inderringene 1 og 2 og endvidere i forhold til mellemringene 4 et tyndere tværsnit. Den ligger tilbagetrukket i afstanden Y i forhold til de kappefladen dannende ydre smalle kanter 21 af ribberne 15.Each stabilizer ring 18 has a thinner cross-section relative to the inner rings 1 and 2 and furthermore to the intermediate rings 4. It is retracted at the distance Y relative to the outer narrow edges 21 of the ribs 15 forming the sheath surface.
De brede flader 22 af hver to ved siden af hinanden beliggende ribber 15 er skiftevis rettet i spolens radialretning R og ved naboribben 15 hældet i forhold til radialretningen R. Denne sidstnævnte hældning i forhold til radialretningen R betinger, at de brede flader 22 af den ene af hver to, i samme tværsnitsplan anbragte ribber 15 er rettet mod linjen L, som skærer radialretningen R under vinklen Y·The wide faces 22 of each two adjacent ribs 15 are alternately directed in the radial direction R of the coil and at the adjacent rib 15 inclined relative to the radial direction R. This latter inclination relative to the radial direction R implies that the wide faces 22 of each two ribs 15 arranged in the same cross-sectional plane are directed to the line L which intersects the radial direction R at the angle Y ·
