Description
Når man ønsker å spole av fra en spole denWhen you want to uncoil from a coil it
tråd den inneholder, anbringer man spolen på en avrullings-anordning som vanligvis er avbremset for å gi tråden en viss spenning. thread it contains, the spool is placed on an unwinding device which is usually braked to give the thread a certain tension.
En slik arbeidsmåte er fullstendig tilfreds-stillende for mindre skjøre tråder rullet opp på små spoler. Når det derimot dreier seg om skjøre tråder, på grunn av deres finhet og/eller deres art (glassfibre), må den spenning som påføres under deres avspoling, være svak og meget regelmessig og det samme gjelder når de spoles av fra store og tunge spoler. I et slikt tilfelle er imidlertid de uregelmessigheter som frembringes ved friksjoner, ubalanse og treghet i spolene,blir en enkel avbremsing av disse ubrukelig. Such a method of working is completely satisfactory for less fragile threads wound up on small spools. However, when it comes to fragile threads, due to their fineness and/or their nature (glass fibres), the tension applied during their unwinding must be weak and very regular and the same applies when they are unwound from large and heavy spools . In such a case, however, the irregularities produced by friction, imbalance and inertia in the coils, a simple braking of these becomes useless.
For det formål å tillate en fullkommen avspoling og uten fare for brudd på en skjør tråd fra en tung spole, er det kjent å anvende en anordning for avrulling omfattende en mekanisme som kan påføre et drivmoment eller motarbeide spolens rotasjon under avrulling av tråden på denne, hvilken mekanisme omfatter en drivmotor og en retarda-sjonsbremse for spolen, hvilke er styrt ut fra en sender som er følsom for spenningen i tråden ut fra spolen for å kunne bibeholde nevnte spenning konstant. En slik anordning kan sikre en meget fin regulering av trådspenningen ved å styre dreiehastigheten for spolen på en aktiv måte og ikke bare ved enkel avbremsing. For the purpose of allowing a perfect unwinding and without the risk of breaking a fragile thread from a heavy spool, it is known to use a device for unwinding comprising a mechanism that can apply a driving torque or counteract the rotation of the spool during unwinding of the thread thereon, which mechanism comprises a drive motor and a deceleration brake for the coil, which are controlled from a transmitter which is sensitive to the tension in the thread from the coil in order to maintain said tension constant. Such a device can ensure a very fine regulation of the thread tension by controlling the speed of rotation of the spool in an active way and not just by simple braking.
Ifølge oppfinnelsen er bare motoren i den nevnte mekanisme styrt ut fra den nevnte mottager, mens bremsen på-fører spolen et konstant bremsemoment. Det passer å regulere det pådratte konstante moment stadig ved bremsing av spolen til en større verdi enn den maksimale verdi av alle uønskede momenter tilsanvmen som virker på spolen under dennes dreining på grunn av mangelfulle konstruksjoner eller monter-inger som den uunngåelig medfører, slik at det vil være det med hensikt på spolen påførte bremsemoment som vil være overveiende og bestemme det moment som motvirker totalt og virker på spolen, hvilket omfatter det moment som er nød-vendig for å overvinne tregheten i spolen under retarda-sjonen. According to the invention, only the motor in the aforementioned mechanism is controlled from the aforementioned receiver, while the brake applies a constant braking torque to the coil. It is appropriate to regulate the applied constant torque constantly when braking the coil to a greater value than the maximum value of all unwanted torques in relation to the coil acting on the coil during its rotation due to defective constructions or assemblies which it inevitably entails, so that will be the braking torque intentionally applied to the coil which will be predominant and determine the torque which totally opposes and acts on the coil, which includes the torque which is necessary to overcome the inertia of the coil during deceleration.
Motoren kan være matet ved hjelp av en elektronisk hastighetsvariator med en kvadrant styrt ved hjelp av mottageren for trådspenningen, hvilket er en fordelaktig løsning, fordi en variator med en kvadrant er et forholds-vis enkelt og lite kostbart apparat. Forøvrdg er den effekt som forbrukes av bremsen, i praksis meget liten. The motor can be fed by means of an electronic speed variator with a quadrant controlled by means of the receiver for the wire tension, which is an advantageous solution, because a variator with a quadrant is a relatively simple and inexpensive device. In fact, the power consumed by the brake is very small in practice.
Den etterfølgende beskrivelse under henvisning til tegningen som et rent eksempel, tillater bedre forstå-else av oppfinnelsen, idet den eneste tegning skjematisk viser en anordning ifølge oppfinnelsen. The following description, with reference to the drawing as a pure example, allows a better understanding of the invention, as the only drawing schematically shows a device according to the invention.
På tegningen kan ses en spole 1 fylt med en tråd 2 og montert på en avspolingsanordning 3. Ved utgangen fra spolen danner tråden 2 mellom to skiver 4, 5 en løkke 6 som går over en bevegelig skive 7. Skiven 7 som hører til en vippearm 8, tjener til å måle spenningen Q i tråden 2 og er dannet av en arm 9 som vipper om et punkt 9a og en trekk-fjær 10 som søker å øke omfanget av løkken 6. Armen 9 er ved hjelp av et tannhjulsinngrep 11, 12 koblet til et potensiometer 13 forbundet med inngangen til en elektronisk hastighetsvariator 14 med en kvadrant, hvis utgang mater en motor 15 forbundet med avspolingsanordningen ved hjelp av en rem 16. The drawing shows a spool 1 filled with a thread 2 and mounted on a unwinding device 3. At the exit from the spool, the thread 2 between two disks 4, 5 forms a loop 6 that goes over a movable disk 7. The disk 7 which belongs to a rocker arm 8, serves to measure the tension Q in the thread 2 and is formed by an arm 9 which tilts about a point 9a and a tension spring 10 which seeks to increase the extent of the loop 6. The arm 9 is by means of a gear engagement 11, 12 connected to a potentiometer 13 connected to the input of an electronic speed variator 14 with a quadrant, the output of which feeds a motor 15 connected to the unwinding device by means of a belt 16.
En bremse 17 pådrar stadig et konstant bremsemoment på avspolingsanordningen 3. A brake 17 constantly exerts a constant braking torque on the unwinding device 3.
Når spolens 1 hastighet forandrer seg, for-skyves skiven 7 på vippearmen 8 og styrer over drivkjeden 9, 11, 12, 13 og 14 motoren 15 slik at motormomentet som drivkjeden mater, følgelig vil variere. When the speed of the coil 1 changes, the disc 7 on the rocker arm 8 is pushed forward and controls the motor 15 over the drive chain 9, 11, 12, 13 and 14 so that the motor torque supplied by the drive chain will consequently vary.
Ved stabilisert vanlig drift rører ikke vippearmen seg og trådens spenning er Q = F , idet F er kraften av fjæren 10. Det er tilstrekkelig<2>å regulere F for å justere spenningen Q. In stabilized normal operation, the rocker arm does not move and the thread's tension is Q = F , with F being the force of the spring 10. It is sufficient<2>to regulate F to adjust the tension Q.
Når den lineære hastighet av avspolingen av tråden 2 ikke er konstant eller når spolen 1 er av dårlig 1 kvalitet, blir tilsvarende uregelmessigheter kompensert ved hjelp av små forskyvninger av vippearmen 8. When the linear speed of the unwinding of the thread 2 is not constant or when the coil 1 is of poor 1 quality, corresponding irregularities are compensated by means of small displacements of the rocker arm 8.
Tregheten og friksjonsmomentet for vippearmenThe inertia and friction moment for the rocker arm
8 kan medføre variasjoner i trådspenningen Q. For å gjøre 8 can cause variations in the thread tension Q. To do
disse variasjoner umerkelige, er det hensiktsmessig mest mulig å redusere betydningen av disse fremstillingsparametere som påvirker vippearmen. I drift vil motorens moment motvirke bremse-momentet, idet det siste reguleres til en større verdi enn den maksimale verdi av alle uønskede momenter som virker på spolen 1 i bevegelse og følger med dens montering (friksjoner) og dens konstruksjon (treghet, ubalanse), for å oppheve svingninger i disse uønskede momenter. Når vippearmen 8 forskyver seg oppover, øker motorens moment og når den forskyver seg nedover, avtar motorens moment slik at det fremkomne moment pådratt spolen av hele utstyret med motoren 15 og bremsen 17 viser seg modulert slik at trådspenningen 2 bibeholdes konstant og lik verdien these variations are imperceptible, it is expedient as much as possible to reduce the importance of these manufacturing parameters that affect the rocker arm. In operation, the motor's torque will counteract the braking torque, the latter being regulated to a greater value than the maximum value of all unwanted torques that act on coil 1 in motion and accompany its assembly (frictions) and its construction (inertia, imbalance), to eliminate fluctuations in these unwanted moments. When the rocker arm 8 moves upwards, the motor's torque increases and when it moves downwards, the motor's torque decreases so that the resulting torque applied to the coil by the entire equipment with the motor 15 and the brake 17 is modulated so that the thread tension 2 is maintained constant and equal to the value
