Definitions
- the invention relates to a method for winding a thread running at a constant speed according to the preamble of claim 1 and a winding machine according to the preamble of claim 4.
- the thread running at a constant speed is wound up into a bobbin by means of a driven winding spindle.
- the winding speed In order to be able to wind up the thread with a uniform thread tension, the winding speed must be equal to the feed speed of the thread.
- the thread is guided over a dancer arm roll arranged between two fixed thread guides.
- the dancer arm roller is attached to a dancer arm loaded with a torque. This creates a slack in the thread between the two thread guides.
- the speed of the winding spindle and thus the peripheral speed of the bobbin is regulated by a control loop so that the thread always has the same sag from the beginning to the end of the winding travel.
- the absolute thread length changes between the thread guide arranged upstream of the traversing and the depositing point of the thread on the bobbin due to the traversing movement with each traversing stroke of the traversing thread guide.
- the dance arm must be Follow position with a frequency that corresponds to twice the traversing frequency. Due to its mass and geometric shape, the dancer arm cannot follow this frequency. The necessary amplitude and frequency of the movement of the dancer arm role or the dancer arm cannot be achieved with increased speed of the traversing. This leads to changes in thread tension, whereby the thread is either overstretched or slips ver.
- a wire is guided over a deflection device on a dancer arm in a payout spool.
- the dancer arm is coupled to a brake which is tensioned by a spring acting on the dancer arm.
- a more or less strong braking force is generated by the wire tensile force acting on the deflection device of the dancer arm. Relatively low wire tensions already result in a very high braking force.
- the invention compensates for the change in length caused by the traversing of the thread.
- the winding spindle speed is controlled so that the winding speed of the thread is equal to the feeding speed of the thread.
- the invention now provides a solution as to how the length of the thread can be kept constant from the point of contact of the bobbin to the thread guide upstream of the dancer arm roll, to which the thread runs at a constant speed.
- the dancer arm must make a compensation stroke which is dependent on the number of wraps and which is a fraction of the distance of the change in length.
- the dancer arm Even with double wrapping, the amplitude of the dancer arm movement is halved compared to the previous single wrapping. This means that the dancer arm, which is subject to inertia, only has to travel halfway in the time unit and thus experiences a significantly lower acceleration. This also reduces the speed of the dancer arm proportionally depending on the number of wraps.
- the dancer arm can compensate for the difference in length even at higher frequencies without overstretching or folding the thread.
- Another advantage of the invention is that the weight of the dancer arm roller or the torque acting on the dancer arm also has a fraction of the thread tension depending on the number of wraps. With a double loop, only a quarter of the force acting on the dancer arm role is effective in the thread.
- the method according to the invention is therefore also particularly suitable for winding threads with fine titers that are wound at relatively low thread tensions.
- the defined multiple wrapping of the dancer arm roll is formed so that the thread running onto the dancer arm roll is first passed one or more times to a fixed thread guide and back before it runs off. This results in several partial wraps on the dancer arm role.
- the winding machine according to the invention for using the method is characterized in that the thread is guided on the dancer arm roller in each case in a thread running groove. This ensures that even with constant vibrations of the dancer arm, the thread is safely guided around the dancer arm roll.
- the thread running grooves have the same diameter.
- the rollers can be designed as co-rotating or counter-rotating rollers. In this way, Z-shaped, S-shaped or O-shaped wraps of the thread can be achieved.
- the fixed thread guide which is wrapped around several times also has freely rotatable rollers per wrap.
- the thread deflections can therefore take place on the dancer arm roller above the stationary thread guide both via rollers which are rotatably mounted independently of one another and via a single continuous cylindrical roller.
- the multiple deflection of the thread advantageously takes place between the dancer arm roll and one of the two fixed thread guides, which form the slack of the thread with the dancer arm roll.
- Fig. 1 shows schematically an embodiment of the winding machine according to the invention
- 2 shows a synchronous dancer arm roller for thread guidance
- 3 shows a counter-running dancer arm roller for thread guidance
- Fig. 4 is a counter-running dancer arm role for thread guidance.
- FIG. 1 an embodiment of a dishwasher is shown in perspective.
- the winding head is arranged on a vertical stand plate 1.
- the traversing device 8 for traversing the incoming thread 2 is assigned to the winding spindle 3.
- the traversing device 8 parallel to the bobbin 4 consists of a housing 6, in which a reversing thread shaft is rotatably mounted, and the traversing thread guide 7, which is moved back and forth by the reversing thread shaft in a straight guide and which lays the thread 2 on the bobbin.
- a support roller 20 is freely rotatably mounted on the housing 6 of the traversing device.
- the traversing device 8 with the reversing thread shaft is fastened to a slide 21.
- the slide 21 is mounted in a slide guide 22, which allows a linear movement - radial or secant to the coil.
- the carriage 21 is spring-loaded in such a way that the traversing device 8 is supported with its support roller 20 against the coil surface during the entire winding travel, but can avoid the increasing diameter of the coil 4.
- the fed thread 2 runs, before it is laid on the bobbin surface by the traversing thread guide 7, over two fixed thread guides 14 and 15, between which a dancer arm 9 with a dancer arm roller 10 is arranged pivotably.
- the dancer arm roll 10 rests on the thread under the weight of the dancer arm 9.
- the spindle motor 18 for driving the winding spindle 3 is fastened.
- the winding spindle drive is connected to the reverse thread shaft in such a way that the ratio of the winding spindle speed and the traversing frequency remains constant throughout the winding cycle.
- the thread 2 first runs onto the thread guide 14.
- the thread guide 14 consists of a guide roller 11 which is rotatably mounted on an axis 13.
- the axis 13 is attached to the stand plate 1.
- the thread then runs from the thread guide 14 to the dancer arm roller 10.
- the dancer arm roller has two thread running grooves 32.1 and 32.2 which are formed in parallel next to one another.
- the thread that runs from the thread guide 14 is deflected in one of the thread running grooves and guided to the second thread guide 15.
- the thread guide 15 consists of the thread guide roller 12 which is rotatably mounted on an axis 16.
- the axis 16 is attached to the stand plate 1.
- the thread guide roller 12 also has two thread guide grooves with the same diameter.
- the thread is now passed around one of the guide grooves.
- the thread then wraps around the second thread guide groove of the dancer arm roller 10, in order then to run to the traversing thread guide 7 via the second thread guide groove of the guide roller 12 of the thread guide 15.
- the thread runs at a constant speed. This forms between the thread guides 14 and 15 due to the constant weight of the Dancer arms 9 with the dancer arm roller 10 - possibly reinforced by a torque sensor 24 - a sag.
- the size of this slack is determined on the one hand by the feed speed of the thread and on the other hand by the winding speed.
- the size of the sag is adjusted to a constant value.
- the axis 31 of the dancer arm is connected to a rotation sensor 19.
- the position and the speed of the change in position of the dancer arm are detected by the rotary sensor 19.
- the rotation sensor 19 is coupled to a control device 17.
- the spindle motor 18 is controlled by the control device 17.
- the dancer arm 9 and the control device 17 are therefore included in a control loop by means of which the sag of the thread loop between the thread guides 14 and 15 is corrected.
- the control device 17 is set such that the high-frequency vibrations of the dancer arm, which arise due to the oscillating movement, do not lead to the control of the spindle motor.
- the dancer arm will thus vibrate synchronously with the traversing frequency, so that the traversing does not affect the winding speed and the feeding speed. This allows a winding with an essentially constant thread tension and thus a good package build. Since the force of the dancer arm acting on the dancer arm role is absorbed by the number of wraps, the force to be absorbed in the thread is reduced. This makes it possible to load the dancer arm with a higher torque or a harder spring, which in turn allows an increase in frequency.
- the dancer arm role consists of a first role 25.1 and a second role 25.2.
- the roller 25.1 is fastened to a shaft 26 in its central region.
- the shaft 26 is supported at one end by the bearings 28 in a hollow cylindrical axis 29.
- the second roller 25.2 is rotatably supported by a bearing 27.
- the roller 25.1 rotates with the shaft 26.
- the roller 25.2, which is mounted on the rotating shaft, rotates in the same direction of rotation. Only the differential speed of the two rollers is thus effective on the bearing 27.
- This dancer arm role prevents an impermissibly high tensile force in the thread being induced by slippage, since the movement of the dancer arm leads to different circumferential speeds of the wrapped roles, in particular in the case of multiple wraps.
- Fig. 3 a double counter-rotating dancer arm role is shown. The role
- 25.1 is fastened to a shaft 26.1, which in turn is supported in the hollow cylindrical axis 29 by the bearings 28.1.
- the roller 25.1 has a shoulder 30.1 for receiving a bearing 28.2.
- the approach 30.1 is arranged coaxially to the hollow cylindrical axis 29 on the opposite side of the roller 25.1.
- the approach like the axis, is made hollow-cylindrical in such a way that a shaft 26.2 is rotatably supported by the bearings 28.2 in the inside diameter of the approach.
- the roller 25.2 is attached to the shaft 26.2.
- the roller 25.2 has its own shaft 26.2, which is separate from the roller 25.1, so that both rollers can be rotated in the opposite direction of rotation. This arrangement advantageously allows multiple wraps in the S or Z shape but also the O shape.
- roller 26.2 and 26.3 a counter-rotating direction of any reel is possible without inducing an impermissibly high tensile force in the thread. It is irrelevant which of the three rollers rotates in the opposite direction and which speed difference occurs between the rollers.
- both roller 25.2 or roller 25.3 or rollers 25.2 and 25.3 can have a direction of rotation opposite to roller 25.1.
- the dancer arm rollers shown in FIGS. 2 to 4 can also be used as the thread guide roller of the thread guide 14 or 15.
- the method according to the invention and the winding machine according to the invention ne show a considerably improved bobbin build, especially when winding up very fine threads and, due to the constant thread tension, ensure that the thread is not damaged by overstretching.
