Description
DK 156837 BDK 156837 B
Den foreliggende opfindelse angâr en slâningsmaskine som angivet i indledningen til patentkrav 1.The present invention relates to a mower as set forth in the preamble of claim 1.
I maskiner af denne art er det npdvendigt at tilde!e hver trâd, der 5 slâs, en korrekt afviklingsspænding, og endvidere er det vigtigt, nâr maskinen stopper, at tilvejebringe en bremsevirkning, der er stprre end den, der udpves under afviklings- eller slâningsfasen, for derved at standse de under afvikling værende spoler i samme pjeblik, som maskinen standses.In machines of this kind, it is necessary to give every thread that is struck a correct unwinding voltage, and furthermore, when the machine stops, it is important to provide a braking effect greater than that exerted during unwinding or the mowing phase, thereby stopping the coils that are in operation at the moment the machine is stopped.
1010
Dette er navnlig vigtigt under hensyntagen til, at hastighederne af spolerne kan være af stprrelsesordenen 600-700 omdrejninger pr. minut, og at de, nâr de er fyldt med frisk trâd, har meget stor inerti.This is particularly important, taking into account that the speeds of the coils can be of the order of 600-700 rpm. per minute, and when filled with fresh thread, they have very high inertia.
1515
Det er derfor ved maskiner af den her omhandlede art nidvendigt at udforme disse pà en sâdan mâde, at de foruden at sætte de under slâning værende trâde under spænding kan tilvejebringe en kraftig bremsning af de spoler, der afgiver trâd under slâningen. Hertil 20 kommer, at maskiner af den her omhandlede art samtidig skal kunne udfpre den i det foregâende beskrevne funktion, nemlig at tilvejebringe opvikling af frisk trâd pâ den af hvert spolepars spole, som ikke deltager i slâningen, og denne opvikling af frisk trâd skal ske samtidig med, at slâning finder sted. Der skal derfor ogsà tilveje- 25 bringes mulighed for pâ simpel mâde at omkoble spolerne sâledes, at de i det ene tilfælde udsættes for den i det foregâende forklarede bremsevirkning, og i det andet tilfælde kan drives for opvikling af frisk trâd.It is therefore necessary for machines of the kind in question to design these in such a way that, in addition to putting the thread under tension, it can provide a strong braking of the coils which give thread during the cutting. In addition, machines of this kind must at the same time be able to perform the function described above, namely to provide winding of fresh thread on the coil of each coil pair which does not take part in the turning, and this winding of fresh thread must occur. while mowing takes place. It should therefore also be possible to simply switch the coils in such a way that in one case they are exposed to the braking effect explained above and in the other case can be driven to wind up fresh thread.
30 Det er formàlet med den foreliggende opfindelse at anvise en maski-ne, der Ipser disse problemer, og dette opnâs ifplge opfindelsen ved, at maskinen er udformet som anf0rt i den kendetegnende del af patentkrav 1.It is an object of the present invention to provide a machine which solves these problems and this is achieved according to the invention in that the machine is designed as set forth in the characterizing part of claim 1.
35 Takket være det nævnte skivepar og mekanismen til forbindelse af hver af disse og den tilhprende spole kan ét spolepar let omstilles, nemlig sâledes at parrets ene spole overgâr fra at tjene til slâning, medens parrets anden spole tjener til opvikling af frisk trâd, og til en tilstand, hvor det omvendte er tilfældet. Samtidig 235 Thanks to said disk pair and the mechanism for connecting each of them and the associated coil, one coil pair can be easily switched, namely, that one pair of coil transitions from serving to mowing, while the other coil of the pair serves to wind up fresh thread, and to a condition in which the reverse is the case. At the same time 2

bevirker den i et med spolen udformede bremsetromle med tilhprende bremsebând, at en spole, nâr den tjener til slâning, kan bremses til opnâelse af den pnskede slâningsspænding i den pàgældende spoles trâd, og endvidere kan den pàgældende spole, nâr maskinen standses, 5 afbremses umiddelbart, takket være vægtstangssystemet.in a brake drum designed with the coil, with associated braking band, a coil, when used for mowing, can be braked to obtain the desired mowing voltage in the thread of the coil in question, and furthermore, the coil in question can be stopped immediately when the machine is stopped, 5 , thanks to the lever system.
Opfindelsen skal herefter forklares nærmere under henvisning til tegningen, hvor 10 fig. 1 viser et sidebillede af en udfdrelsesform for maskinen ifplge opfindelsen, der for overskuelighedens skyld kun omfatter to spole-par, fig. 2 viser et billede set fra siden af en skive, der er anbragt 15 umiddelbart ved siden af en spole, og endvidere viser denne figur en bremse til tilvejebringelse af den pnskede spænding i den pàgældende spoles trâd og til fuldstændig afbremsning af den pàgældende spole, fig. 3 en del af et længdesnit af en détaillé til maskinen til 20 belysning af trâdfpringen fra en spole under slâning, fig. 4 et perspektivisk billede af en del af maskinen til belysning af trâdfpringen fra en spole, og 25 fig. 5 et billede til belysning af en mekanisme til sammenkobling af en skive og en spole og til frikobling af disse i forhold til hinanden.The invention will now be explained in more detail with reference to the drawing, in which: FIG. 1 shows a side view of an embodiment of the machine according to the invention, which, for the sake of clarity, comprises only two coil pairs; Figure 2 shows a side view of a disc disposed 15 immediately adjacent to a coil, and furthermore, this figure shows a brake to provide the desired tension in the thread of the coil in question and to completely decelerate the coil in question; . 3 is a fragmentary longitudinal sectional view of the machine for illuminating the thread spring from a coil during mowing; FIG. 4 is a perspective view of a portion of the machine for illuminating the thread spring from a coil; and FIG. 5 shows an image for illustrating a mechanism for interconnecting a disc and a coil and for disconnecting them relative to each other.
Pâ tegningen er der vist en maskine 1 til at si à flere trâde 2 30 omkring en central kærnetrâd 3, f.eks. til slâning af et tov eller til slâning af et stærkstrpmskabel med afskærmning.In the drawing, a machine 1 is shown to say in several threads 2 around a central core thread 3, e.g. for mowing a rope or for mowing a strong-current cable with shielding.
Maskinen er forsynet med flere enheder 4, hvis antal er lig med antallet af trâde, der skal slâs. Hver enhed omfatter en hul aksel 5 35 (fig. 1,3), der er frit drejeligt lejret i en central understdtning 6, et par spoler 7,8, der er lost drejeligt lejret pà akslen, nemlig en spole til hver sin side for den tilhprende understptning. Hver spole til hvert spolepar anvendes skiftevis til slâning og til opvikling af frisk trâd, idet der skiftes mellem disse funktioner i 3The machine is equipped with several units 4, the number of which is equal to the number of threads to be cut. Each unit comprises a hollow shaft 5 35 (Fig. 1.3) freely pivotally mounted in a central support 6, a pair of spools 7,8 loosely pivotally mounted on the shaft, namely a spool for each side thereof. the accompanying support. Each coil for each coil pair is used alternately for mowing and winding of fresh thread, alternating between these functions in 3

efter hinanden f0lgende trin. Mellem hver spole og den centrale understptning er der l0st lejret en skive, henholdsvis 9 og 10, og hver skive bærer en trâdstyringsarm 11 med et trækhjul 12 til styring af trâden fra den tilh0rende spole under slâningsfasen.successive steps. Between each coil and the central support, a disc, 9 and 10, respectively, is loosely mounted, and each disc carries a thread guide arm 11 with a pull wheel 12 for controlling the thread from the associated coil during the mowing phase.
5 Trâdfpringsarmene 11 bevæges omkring de hule aksler 5 sammen med skiverne 8 og 9, nâr disse drives. Til yderligere styring af en trâd 2 under slâning findes der styretrisser 13 ved indgangsenden til hver af de hule aksler. Endvidere h0rer der til hver enhed en trâdfordeler 14, der tjener til fordeling af frisk trâd pâ en spole, 10 nâr denne pâvikles ny trâd.5 The thread spring arms 11 are moved around the hollow shafts 5 together with the washers 8 and 9 as they are driven. For further control of a thread 2 during mowing, there are guide blades 13 at the entrance end of each of the hollow shafts. Furthermore, each unit includes a thread distributor 14 which serves to distribute fresh thread on a coil 10 when the new thread is wound.
De hule aksler 5 til enhederne 4, hvoraf der for overskuelighedens skyld kun er vist to, er anbragt pà linie med hinanden og har afstand fra hinanden mellem deres mod hinanden vendende ender, 15 sâledes at det pâ fordelagtig mâde er muligt let at forbinde enden af en trâd, der er blevet afviklet fra et spolepars ene spole 8 under slâningsfasen, med enden af den friske trâd, som er blevet opviklet pâ det pâgældende spolepars anden spole 7.The hollow shafts 5 of the units 4, of which for the sake of clarity only two are shown, are aligned with each other and spaced from one another between their opposite ends, 15 so that it is conveniently possible to connect the end of the a thread that has been unwound from one coil pair one coil 8 during the mowing phase, with the end of the fresh thread wound on the coil pair second coil 7.
20 En hjælpeaksel 15 trækker ved hjælp af tandhjul eller tilsvarende drivorganer, der er anbragt pâ understptningerne 6, akslerne 5 og de dermed forbundne organer. Under slâningsfasen er en spole sammen-koblet med den tilhprende skive 10 ved hjælp af en sammenkoblings-mekanisme 58' som vist i fig. 5 under slâningen, hvorimod denne 25 sammenkoblingsmekanisme 58' er udkoblet under opspoling af frisk trâd, hvorunder de spoler, der forsynes med trâd, drives ved hjælp af separate drivorganer, som ikke er vist pâ tegningen.An auxiliary shaft 15 pulls by means of cogs or similar drive means disposed on the supports 6, the shafts 5 and the associated means. During the mowing phase, a coil is coupled to the adherent disk 10 by means of a coupling mechanism 58 'as shown in FIG. 5 during the turning, whereas this coupling mechanism 58 'is switched off during rewinding of fresh thread, during which the coils provided with wire are driven by separate drive means not shown in the drawing.
Aile enhederne 4 er anbragt mellem en kærnetràdsafviklingsstand 16 30 og en slâningsstation 17, der omfatter en hulplade 18 til trâdene 2's passage, og denne plade roterer sammen mend den sidste enheds aksel 5. Slâningsstationen 17 omfatter yderligere en matrice 19, som er fastgjort pâ en sokkel 20 og konventionelle træk- og optagnings-organer, der ikke er vist.All of the units 4 are disposed between a core winding stand 16 30 and a mowing station 17 which includes a hole plate 18 for the passage of the wires 2, and this plate rotates together with the last unit shaft 5. The mowing station 17 further comprises a die 19 secured to a socket 20 and conventional pulling and picking means not shown.

Trâdene 2 og kærnetrâden 1 styres sâledes inde i akslerne 5 og er underkastet det træk, der tilvejebringes efter slâningsstationen 17.The strands 2 and the core strut 1 are thus guided inside the shafts 5 and are subjected to the tension provided after the mowing station 17.
Det vil forstâs, at nâr maskinen bruges til fremstilling af 4It will be understood that when the machine is used for making 4

flerlagsdugter, f.eks. tolagsdugter, deles maskinenhederne i to efter hinanden f0lgende grupper, nemlig én til hvert lag, og hver gruppe omfatter enheder, der har rotationsretninger og hastigheder, der er 1 ig med eller forskellige fra rotationsretningerne og ha-5 stighederne af enhederne i den anden gruppe, sâledes at lagene slâs med samme eller skiftende retninger. I dette tilfælde er hver gruppe endvidere forsynet med en tilhprende hulplade til trâdenes passage og med en dertil hprende matrice.multilayer cloths, e.g. two-layer cloths, the machine units are divided into two consecutive groups, one for each layer, and each group comprises units having rotational directions and velocities 1 µg with or different from the directions of rotation and the velocities of the units of the second group. so that the layers are struck in the same or changing directions. In this case, each group is further provided with a supporting hole plate for the passage of the threads and with a corresponding die.
10 Fordelerne 14, der fordeler de trâde, der skiftevis opvikles pâ den ene eller den anden spole 7,8 til hvert par, kan være udformet pâ den mâde, der er beskrevet i beskrivelsen til samme anspgers danske patentanspgning nr. 4610/80.10 The distributors 14, which distribute the threads which are alternately wound on one or the other coil 7,8 to each pair, may be designed in the manner described in the description of the same applicant's Danish patent application No. 4610/80.
15 Hver fordeler 14 omfatter en arm 21, der kan drejes i vandret plan 180e, sâledes at fordeleren 14 kan anvendes skiftevis til den ene og til den anden spole til hvert par, og endvidere kan fordeleren 14 bevæges i retning parai!elt med aksen for den spole, der er under pâvikling af frisk trâd i retning frem og tilbage svarende til 20 afstanden mellem flanger pâ spolen. En endetrisse 22, der bevæges sammen med armen 21, styrer for hver enhed den fra en fpdetromle kommende trâd i forhold til den spole, der skal pâvikles frisk trâd.Each distributor 14 comprises an arm 21 which can be rotated in horizontal plane 180e so that the distributor 14 can be used alternately for one and the other coil for each pair, and furthermore the distributor 14 can be moved in the direction parallel to the axis of the coil that is being wound in the forward and backward direction of fresh thread corresponding to the distance between flanges on the coil. An end roller 22, which is moved together with the arm 21, controls for each unit the thread coming from a feed drum relative to the coil to be wound fresh thread.
Under opviklingsfasen drives de pâgældende spoler fra en central 25 aksel, der ikke er vist, og som er anbragt mellem enhederne, og som som nævntdrives af en motor, der er uafhængig af drivningen af akslerne 5.During the winding-up phase, the coils in question are driven from a central shaft which is not shown, which is disposed between the units, and as mentioned, driven by a motor independent of the drive of the shafts 5.
Hver spole er forsynet med en bândbremse. I fig. 2 er der vist en 30 sâdan bândbremse 23, nemlig til spolen 8, og den dertil hdrende skive 10. Bândbremsen 23 virker pâ spolen 8 ved hjælp af et vægt-stangssystem 24, der er fplsomt overfor trækvariationer i den fra spolen 8 afviklede trâd, og foruden selve bândbremsens bremse-bând 23 omfatter bândbremsen et element 25, der er anbragt mellem 35 vægtstangssystemet 24 og bremsebândet 23, sâledes at det overfprer en forandring, som er stprre end en forud fastslàet stprrelse i den afviklede trâds træk, hvilket element 25 er i stand til at variere bândets bremsning af spolen og derfor justere trækket i den afviklede trâd til en praktisk taget konstant værdi.Each coil is equipped with a band brake. In FIG. 2, there is shown such a band brake 23, namely for the coil 8, and the associated disk 10. The band brake 23 acts on the coil 8 by means of a barbell system 24 which is sensitive to tensile variations in the thread wound from the coil 8, and in addition to the braking band 23 of the band brake itself, the band brake comprises an element 25 disposed between the barbell system 24 and the brake band 23 so as to transmit a change greater than a predetermined size of the wound tread feature, which element 25 is capable of varying the band braking of the coil and therefore adjusting the tension of the wound thread to a practically constant value.

Bremsebândet 23 er viklet en forud fastlagt vinkel omkring omkredsen af en til spolen hprende bremsetromle 26, og bândets ene ende 27 er forbundet med et fast punkt pâ skiven 10, medens bândets anden ende 28 er pâvirket af fjederkraften fra en f0rste fjeder 29, der har 5 sâdanne karakteristika og er anbragt pâ skiven 10 pâ en sâdan mâde, at der til bremsebândet overfpres et bremsemoment, som er i stand til at stoppe spolen 8, selv nâr denne er fyldt med trâd og roterer med arbejdshastigheden og i samme pjeblik, slâningsmaskinen stand-ser.The brake band 23 is wound at a predetermined angle about the circumference of a brake drum leading to the coil, and one end 27 of the belt is connected to a fixed point on the disc 10, while the other end 28 of the belt is actuated by the spring force of a first spring 29 having 5 such characteristics and are arranged on the disc 10 in such a way that a braking torque capable of stopping the coil 8 is applied to the braking belt even when it is full of thread and rotates at the operating speed and at the same moment the mower is capable of brazilian trip.
1010
Til bremsen 23 hprer der en plade 30, der er drejeligt lejret pâ en tap 31, der er fastgjort til skiven 10 og stâr vinkelret pâ denne. Bremsebândets anden ende 28 er forbundet med pladen 10 til den ene side for tappen 31, og det samme gælder den ene ende af den nævnte 15 fprste fjeder 29. Fjederen 29 er strakt, og dens anden ende 33 er forbundet med en de! 34, som bæres af skiven 10. Den ene ende 35 af det element 25, der overfprer trâdtrækkets variation mellem vægt-stangssystemet 24 og bremsebândet 23, er fastgjort til pladen 30 ved den modsatte side i forhold til tappen 31. Enden 32 af den fprste 20 fjeder 29 og enden 28 af bremsebândet er fastgjort til pladen 30 til samme side for tappen 31.To the brake 23 is mounted a plate 30 pivotally mounted on a pin 31 attached to the washer 10 and perpendicular thereto. The other end 28 of the brake band is connected to the plate 10 to one side of the pin 31, and the same applies to one end of the first 15 spring 29. The spring 29 is stretched and its other end 33 is connected to one. 34, which is supported by the disk 10. One end 35 of the element 25 transmitting the traction variation between the lever bar system 24 and the brake band 23 is attached to the plate 30 at the opposite side relative to the pin 31. The end 32 of the first 20 springs 29 and the end 28 of the brake band are attached to the plate 30 to the same side of the pin 31.
Ved hjælp af den i det foregâende beskrevne konstruktion vil den nævnte fprste fjeder 29 tilvejebringe en drejning af skiven 30 i 25 retning til stramning af bremsebândet 23 omkring bremsetromlen. Den kraft, som fjederen 29 er i besiddelse af, er tilstrækkelig til herved helt at afbremse den tilhdrende spole 8.By means of the construction described above, said first spring 29 will provide a rotation of the disc 30 in the direction of tightening the brake band 23 around the brake drum. The force possessed by the spring 29 is sufficient to thereby completely decelerate the associated coil 8.
Denne bremsevirknings udlosning afhænger af den virkning, der udpves 30 pâ pladen 23 af elementet 25, nemlig i overensstemmelse med sving-ninger af vægtstangssystemet 24, der sprger for justering af tràd-spændingen, sàledes som det nu vil blive forklaret.The release of this braking action depends on the effect exerted on the plate 23 by the element 25, namely in accordance with oscillations of the lever system 24, which advocates adjusting the thread tension, as will now be explained.
Vægtstangssystemet 24 omfatter en vægtstang 36, jfr. fig. 3 og 4, 35 der er drejeligt lejret pâ en tap 37, som er bâret af en understpt-ning 38, som strækker si g i en retning, der forlpber i det væsent-lige parallelt med spolen 8's akseretning, og som bæres af den tilh0rende skive 10. Vægtstangen 36's ene ende 39 bærer en trisse 41, der er drejeligt lejret omkring en tap 42, hvis omdrejningsakse 6The lever system 24 comprises a lever 36, cf. FIG. 3 and 4, 35 pivotally mounted on a pin 37 carried by a support 38 extending in a direction extending substantially parallel to the axis of the coil 8 and carried by the associated washer 10. One end 39 of lever 36 carries a pulley 41 pivotally mounted about a pin 42 whose axis of rotation 6
DK 156837 BDK 156837 B
forl0ber stort set radiait i forhold til den tilhorende spole 8's akse. Vægtstangen 36's anden ende 40 samvirker (ved 48') med den ene ende 48 af en yderligere vægtstang 46, der er drejeligt lejret omkring en tap 47, som er fastgjort til skiven 10, og den yderligere 5 vægtstangs anden ende 45 er forbundet med den ene ende af en yderligere fjeder 43, hvis anden ende er fastgjort til skiven 10 ved et fast sted 44. Sammenkoblingen mellem vægtstangen 40 og den yderligere vægtstang 46 udgores af en gaffe!-tapforbindelse, sâledes som vist ved 48' i fig. 2 og 3.extends substantially radially to the axis of the associated coil 8. The other end 40 of the lever 36 interacts (at 48 ') with one end 48 of an additional lever 46 pivotally mounted around a pin 47 attached to the disc 10, and the other 5 lever's other end 45 is connected to it. one end of an additional spring 43, the other end of which is fixed to the washer 10 at a fixed location 44. The connection between the lever 40 and the additional lever 46 is formed by a gaff! pin connection, as shown at 48 'in FIG. 2 and 3.
1010
Ved at variere det sted 44, hvor den yderligere fjeder 43's anden ende er fastgjort, kan fjederen 43's kraft indstilles til regulering af trâdspændingen.By varying the location 44 at which the other end of the additional spring 43 is secured, the force of the spring 43 can be adjusted to regulate the thread tension.
15 Den yderligere vægtstang 46 er ved sin ende 48 yderligere forbundet med enden 49 af overforingselementet 25 mellem vægtstangssystemet 24 og bàndbremsen.The additional lever 46 at its end 48 is further connected to the end 49 of the transfer member 25 between the lever system 24 and the tie brake.
Ved den pâ tegningen viste udforelsesform er elementet 25 bojeligt 20 og overforer kun trækkræfter. Dette element kan f.eks. bestâ af en wire eller en nylonsnor. Elementet 25 og den yderligere fjeder 46 er sâledes forbundet med hver sin ende af den yderligere vægtstang 46.In the embodiment shown in the drawing, the element 25 is flexible 20 and transmits only tensile forces. This element may e.g. consist of a wire or a nylon cord. The element 25 and the additional spring 46 are thus connected to each end of the additional lever 46.
Ved den pâ tegningen viste udforelsesform er elementet 25 fort over 25 en trisse 25', som er forbundet med skiven 10, hvilket i forbindelse med elementets bojelighed tillader en bekvem placering af de to fjedre 29 og 43 inden for det rum, der er begrænset af selve elementet 25, og i dette tilfælde kan de to fjedre 29 og 43 placeres meget nær ved skiven 10's omdrejningscentrum, hvorved centrifugal-30 kraftens indflydelse nedsættes, og der opnâs en korrekt bremsning af spolen.In the embodiment shown in the drawing, the element 25 is rapidly above 25 a pulley 25 'which is connected to the disc 10, which, in connection with the element's flexibility, allows a convenient placement of the two springs 29 and 43 within the space limited by the element 25 itself, and in this case the two springs 29 and 43 can be placed very close to the center of rotation of the disc 10, thereby reducing the influence of the centrifugal force and proper braking of the coil.
Bevægelsesbanen for en under afvikling, altsâ slâning, værende trâd 2 vil herefter blive forklaret nærmere under henvisning til fig. 4 35 og fig. 2. Trâden 2, der afvikles fra spolen 8, fores forst til en venderulle 50, fig. 4, der er lost drejeligt lejret pâ en aksel 11, der forlober parallelt med spolens akse, og som er anbragt umiddel-bart uden for dennes fl ange 51. Fra venderullen 50 forlober trâden til trissen 41 pâ vægtstangen 36, og derfra ledes trâden omkring en 7The trajectory of a step 2 being wound down, i.e. striking, will then be explained in more detail with reference to fig. 4 and FIG. 2. The wire 2 wound from the coil 8 is first fed to a turning roller 50, fig. 4, which is loosely rotatably mounted on a shaft 11 extending parallel to the axis of the coil and located immediately outside its flange 51. From the turning roll 50, the thread extends to the pulley 41 on the lever 36, and from there the thread is guided about and 7

trisse 52, der er l0st lejret pâ akslen 11 pâ en sâdan mâde, at denne trisse kan dreje uafhængigt af venderullen 50. Fra trissen 52 ledes tràden til trissen 30, som er fastgjort pâ spoleakslen 5, og derfra forlpber trâden ind i akslen 5 og i retning mod 5 slâningsstationen.pulley 52 loosely mounted on shaft 11 in such a way that this pulley can rotate independently of the turning roller 50. From the pulley 52, the thread is passed to the pulley 30 which is attached to the spool shaft 5, and from there the thread extends into the shaft 5 and towards the 5 mowing station.
I kraft af denne fdring af trâden vil denne blive afbpjet i væsent-lig grad adskillige gange, hvilket bevirker en formindskelse af slâningsmaskinens maksimale rotationsradius, hvilket hovedsageligt 10 skyldes tilstedeværelsen af venderullen 50, hvorfra trâden fpres direkte til trissen 41 med deraf fplgende mulighed for at forpge maskinens hastighed, fordi de radiale dimensioner er reduceret, hvorved problemerne med hensyn til balance og konstruktion er meget begrænsede, sâledes at der opnâs et mindre effekttab som fplge af 15 aerodynamisk modstand.By virtue of this removal of the thread, it will be detected substantially several times, causing a decrease in the maximum rotating radius of the mower, which is mainly due to the presence of the turning roller 50, from which the tree is fed directly to the pulley 41 with the consequent possibility of The speed of the machine is reduced because the radial dimensions are reduced, whereby the problems of balance and construction are very limited, resulting in less power loss as a result of 15 aerodynamic resistance.
Mekanismen 53 til sammenkobling af bândbremsen og skiven 10 skal herefter forklares nærmere under henvisning til fig. 5. Denne mekanisme 53 er permanent fastgjort til skiven 10 og drejer sammen 20 med denne under slâningsfasen. Mekanismen 53 er forbundet med enden 33 af den til bândbremsen hdrende fprste fjeder 29 og er baseret pâ det princip, at fjederen 29 strækkes under slâningsfasen og af fjederenderne tillades at nærme sig hinanden, hvorved bremsen frigdres, nâr maskinen stopper. Som det fremgâr af tegningen omfat-25 ter mekanismen 53 en stift 54, og i skiven 10 findes der et sæde 55, der er beregnet til at modtage enden af stiften, der stâr under pâvirkning af en Tille fjeder 56. Stiften er anbragt ved enden af en vægtstang 57, der er drejeligt lejret omkring en tap 58, som er fastgjort til skiven 10, og enden 33 af fjederen 29 er forbundet med 30 den ende af vægtstangen 57, der vender bort fra stiften 54. Mekanismen har yderligere et greb 58', hvorved vægtstangen 57 kan drejes i urviserretningen, jfr. fig. 2, sâledes at fjederen 29 Ipsnes, og bândbremsen âbnes.The mechanism 53 for interconnecting the tape brake and disc 10 will then be explained in more detail with reference to FIG. 5. This mechanism 53 is permanently attached to the washer 10 and rotates with it 20 during the mowing phase. The mechanism 53 is connected to the end 33 of the first spring 29 associated with the tape brake and is based on the principle that the spring 29 is stretched during the mowing phase and the spring ends are allowed to approach each other, thereby releasing the brake as the machine stops. As can be seen from the drawing, mechanism 53 comprises a pin 54 and in the disc 10 there is a seat 55 intended to receive the end of the pin under the action of a Tille spring 56. The pin is disposed at the end of a bar 57 rotatably mounted around a pin 58 attached to the disc 10 and the end 33 of the spring 29 connected to 30 the end of the bar 57 facing away from the pin 54. The mechanism further has a grip 58 ', whereby the lever 57 can be turned clockwise, cf. FIG. 2, so that the spring 29 Ipsnes and the tape brake are opened.
35 Maskinens arbejdsmâde skal herefter forklares nærmere.35 The operation of the machine must then be explained in more detail.
I den i fig. 1 viste stilling af maskinens dele arbejder spolerne 7 og 7' til opvikling af frisk trâd, og spolerne 8 og 8' virker til slâning. Under opfyldning med frisk trâd er de til spolerne 7 og 7' 8In the embodiment shown in FIG. 1 of the machine parts, the coils 7 and 7 'work for winding fresh thread, and the coils 8 and 8' work for mowing. When filled with fresh thread, they are for coils 7 and 7 '8

h0rende ski ver 9 fastgjort, f.eks. ved hjælp af en tap til den tilhprende centrale understptning 6 med en passende orientering, der er valgt sâledes, at armen 11 er bevæget nedad, og sâledes at enhver forstyrrelse i forhold til trâdfordeleren 14 undgâs. Hver spole 7 5 trækkes under opviklingen af den tidligere omtalte motor, og trâden tilledes fra en fpdetromle eller -rulle, og der udpves en regule-rende virkning pâ de vindinger, der skal dannes ved hjælp af for-deleren 14, som bevæges i den ene eller den anden retning af den bevægelige arm 21 og den tilhprende trisse 22 med en hastighed, som 10 er afstemt i forhold til spolen 7's omdrejningshastighed, sâledes at der aflægges regulære vindingslag.Hearing discs 9 attached, e.g. by means of a pin to the adjacent central support 6 having a suitable orientation selected so that the arm 11 is moved downwardly so as to avoid any interference with the strut 14. Each coil 75 is pulled during the winding of the aforementioned engine, and the thread is fed from a feed drum or roller and a regulating effect is exerted on the turns to be formed by the distributor 14 which is moved in the one or the other direction of the movable arm 21 and the adjacent pulley 22 at a speed 10 which is aligned with the speed of rotation of the coil 7, so that regular winding layers are deposited.
Under slâningsfasen er en spole 8, der skal anvendes hertil, sam-menkoblet med sin tilhprende skive 10, f.eks. ved hjælp af en tap 15 med en passende ikke vist flange pâ akslen 5, der drives af hjælpe-akslen 15, medens genopfyldning af den pâgældende spole med frisk trâd er afbrudt.During the mowing phase, a coil 8 to be used for this is interconnected with its associated disc 10, e.g. by means of a pin 15 with an appropriate flange not shown on the shaft 5 driven by the auxiliary shaft 15, while refilling the current coil with fresh thread is interrupted.
Spolen 8 drejes omkring den tilhdrende aksel 5 som fdlge af det 20 træk, der udpves i trâden 2 af trækorganet, som trækker trâdene gennem slâningsmatricen, og trâden 2 styres under sin passage fra ydersiden og til indersiden af akslen 5 ved, at den fprst f0res omkring venderullen 50, fig. 4, derefter den til vægtstangen 36 h0rende trisse 41, og derfra via trissen 52 ved enden af rullen 50 25 og til trissen 13, som roterer med akslen 5. Kærnetrâden 3 indf0res i akslen 5 samtidig med trâden 2, og kærnetrâden er ogsâ udsat for det træk, der uddves af trækorganet og styres fra afviklingsstanden 16 gennem aile enhederne 4's hule aksler 5 mod slâningsstationen 17.The coil 8 is rotated about the associated shaft 5 as a result of the 20 thrust exerted in the thread 2 of the pulling member which pulls the threads through the mowing matrix and the thread 2 is guided during its passage from the outside to the inside of the shaft 5 by first feeding it about the turning roller 50, FIG. 4, then the blade 41 of the lever 36, and thence via the pulley 52 at the end of the roll 50 25 and to the pulley 13 which rotates with the shaft 5. The core thread 3 is inserted into the shaft 5 at the same time as the thread 2, and the core thread is also exposed to the pull exerted by the pull member and guided from the unwinding stand 16 through the hollow shafts 5 of all the units 4 toward the mowing station 17.
30 Under denne fase er trækket i trâden 2, der passerer trissen 41 og vægtstangen 36, afbalanceret af reaktionskraften fra fjederen 43, fig. 2, og det resulterende træk hidrprende fra denne balancering udpver i kraft af det bpjelige overfpringselement 25 en mindskende virkning pâ bremsebândet 23's afbremsning af spolens bremsetromle 35 26, hvilken bremsning frembringes af fjederen 29.30 During this phase, the tension in the thread 2 passing the pulley 41 and the lever 36 is balanced by the reaction force of the spring 43, fig. 2, and the resultant feature resulting from this balancing exerts, by virtue of the particular transfer element 25, a decreasing effect on the brake band 23's braking of the coil's brake drum 35, which is produced by the spring 29.
Nâr maskinen af en eller anden grund stoppes, bremses skiven 10 separat af en passende bremse, f.eks. en der er pneumatisk drevet, og spolen 8 fortsætter sin rotation i forhold til skiven. Fplgelig 9When for some reason the machine is stopped, the disc 10 is braked separately by a suitable brake, e.g. one which is pneumatically driven and the coil 8 continues its rotation relative to the disc. Accordingly, 9

finder der en slækning af trâden 2 sted, sâledes at den virkning, der af trâden ud0ves pâ bândbremsen 23 gennem trissen 41 og vægt-stangen 36, og som er beregnet til at reducere bremsevirkningen, elimineres. Bremsen, der ikke længere er udsat for det træk, der 5 uddves af elementet 25, kan derfor ud0ve sit maksimale moment, hvilket forârsager en kraftig afbremsning af spolen 8 i forhold til den tilh0rende skive 10.For example, a weakening of the thread 2 takes place so that the effect exerted by the thread on the band brake 23 through the pulley 41 and the lever 36, which is intended to reduce the braking effect, is eliminated. Therefore, the brake, which is no longer subjected to the pull exerted by the element 25, can exert its maximum torque, causing a severe slowing of the coil 8 relative to the associated disc 10.
Ombytningen af de til samme enhed hprende spoler 7 og 8's funktion 10 foretages som fplger: Nâr maskinen stoppes, frigpres spolen 7 fra den motor, der driver spolen 7 for genopvikling af frisk trâd, og skiven 9 forbindes med akslen 5 ved hjælp af den tidligere omtalte, ikke viste fl ange.The exchange 10 of the coils 7 and 8 of the same unit running in the same unit is made as follows: When the machine is stopped, the coil 7 is released from the motor driving the coil 7 for rewinding of fresh thread and the disc 9 is connected to the shaft 5 by means of the former mentioned, not shown flang.
15 Derefter forbindes enden af den trâd, der findes pâ spolen 7 med enden af den trâd, der fandtes pâ den nu tomme spole, som bæres af den enhed, der er nærmest slâningsstationen 19.15 Then the end of the thread found on the coil 7 is connected to the end of the thread found on the now empty coil carried by the unit closest to the mowing station 19.
Slâningsfasen forberedes pâ tilsvarende mâde, for sâ vidt angâr de 20 spoler, der er genopfyldt med trâd under den forudgâende fase for aile maskinens enheder.The mowing phase is prepared in a similar manner in the case of the 20 coils refilled with thread during the previous phase for all units of the machine.
En t0mt spole 8 genopfyldes med frisk trâd pâ fplgende mâde: 25 Grebet 58', fig. 2 og 5, til mekanismen 53 aktiveres, hvorved stiften 54 fjernes fra sit sæde 55 pâ skiven 10, og derved udlpses fjederen 29, hvilket medfprer, at spolen frigpres. Medens spolen 8 nu frit kan rotere, udfpres der fplgende operationer: Fprst drejes skiven 10, sâledes at armen 11 ikke interfererer med den stilling, 30 som fordeleren 14 og dennes trâdstyrearm 21 vil indtage. Den bevæ-gelige arm 21 drejes en vinkel pâ 180e, indtil trissen 22 er pâ linie med spolen 8. Skiven 10 lâses til den tilhprende understpt-ning, og trâdgenopfyldningsmotoren forbindes mekanisk med spolen 8.An empty coil 8 is refilled with fresh thread as follows: 25 Handle 58 ', fig. 2 and 5, to the mechanism 53 is activated, thereby removing the pin 54 from its seat 55 on the disc 10, thereby releasing the spring 29, which causes the coil to be released. While the coil 8 can now rotate freely, the following operations are expressed: First, the washer 10 is rotated so that the arm 11 does not interfere with the position 30 that the distributor 14 and its thread control arm 21 will occupy. The movable arm 21 is rotated at an angle of 180e until the pulley 22 is aligned with the coil 8. The disk 10 is locked to the associated support and the thread refill motor is mechanically connected to the coil 8.
Til sidst fpres trâden, der kommer fra fpdetromlen eller -rullen, 35 omkring trissen 22 og derfra rundt om spolen 8, og genopfyldning af spolen 8 pâbegyndes.Finally, the thread coming from the feeding drum or roller is pressed around the pulley 22 and thereabout around the bobbin 8 and refilling of the bobbin 8 is started.
