Definitions
- the invention relates to a friction feeder the features of the preamble of claim 1.
- friction feeders For the delivery of threads to thread processing machines, especially those that fluctuate over time or have intermittent thread consumption are common so-called friction feeders are used. These point a thread delivery wheel driven at constant speed with a contact surface for the thread. The thread wraps around the thread delivery wheel with a wrap angle, which is usually less than 360 °. In addition, the thread passed through the eye of a thread guide lever, the Lever position influences the wrap angle. The Thread guide lever is mostly by spring force from that Thread delivery wheel biased away. Comes the thread consumption on the thread processing machine to a standstill, the Thread guide lever the thread at least slightly from the thread delivery wheel decreases or decreases the wrap angle, so that the thread delivery stops. The thread consumption thus controls the thread delivery.
- the coefficient of friction between the thread is essential and adjusts the contact surface.
- a Friction lining for example made of plastic or rubber, changes the delivery behavior of the device gradually. Is the Coefficient of friction between the friction lining and the thread tends the thread to stick to the friction lining. This can cause that the friction controlled shutdown, i.e. the delivery stop friction friction, not done correctly. E.g. the thread loosens when the thread guide lever is swung out not from the drum and is therefore conveyed further.
- the thread delivery wheel has, for example, a meandering annular groove Contact surface.
- the contact surface is spoked by a wheel or pins held on a wheel formed in the circumferential direction seen crossing each other at an acute angle to Radial direction are arranged inclined.
- One around the wheel laid thread lies zigzag between the pins or spokes.
- the friction feeder according to the invention has one Vibration generator on the thread acts.
- Vibration generator on the thread acts.
- the thread guide lever the thread delivery wheel, a thread guide element or one other element touching the thread is connected. In this way, especially when the delivery is stopped Loosen the thread from the contact surface of the thread feed wheel much easier and the remaining touch between Thread and thread delivery wheel minimized.
- the static friction can be overcome, what the laying behavior (switching off the thread delivery) significantly improved.
- This is especially true, but not exclusively, for thread delivery bikes that have a covering have a high coefficient of friction or a structured surface, which allows good thread feeding. Also applies this is especially true for threads with a high coefficient of friction to have.
- deposited contaminants such as sizing, oil, leading to adhesion or the like, not or less for sticking the thread to lead.
- the measure taken, the contact between Exposing the thread and thread delivery wheel to a certain vibration thus improves thread design, i.e. the interruption the thread take-up by the thread delivery wheel drastically.
- the supplier according to the invention can be used for various Threads with different friction properties used become.
- the correct function is through the Vibration support is not sensitive to changes the coefficient of friction.
- the thread guide lever both as a swivel lever and as a resilient bracket or be otherwise trained. It is essential that he carries a thread guide, its position in relation on the thread delivery wheel influenced by the thread tension is.
- Rigid levers allow easy adjustment a force biasing the lever, for example by means of a tension spring, the suspension point of which is adjustable. The force setting allows adaptation to different Thread tensions and qualities.
- Resiliently trained Lever lead to particularly simple Constructions.
- the respective one Lever on his from the thread guide End at a storage facility (“second storage facility”) composed. If the lever is rigid, the second allows Storage facility a movable, for example, swiveling storage.
- the storage facility (swivel bearing or rigid version) with the vibration generating device be connected, the thread guide lever and thus also the thread guide element carried by the thread guide lever vibrates. These vibrations can become Communicate more or less to the thread via the thread guide.
- the first storage device for the thread delivery wheel and / or a thread guide element, that arranged in front of or behind the thread delivery wheel is connected to the vibration generating device his.
- a vibration movement is brought about in each case, that can be transferred to the thread. there the vibration movement can be directed as needed his.
- E.g. are oscillations across each Rotation axis, along the respective rotation or swivel axis or possible diagonally to it. Acts the vibration generator on the front or behind the thread delivery wheel arranged thread guide element, the direction of vibration across the thread parallel to the axis of rotation the thread delivery wheel or be directed transversely to this.
- the generation of vibrations can also be superimposed Carry out oscillation so that the corresponding vibrating element not on a linear but on an elliptical or circular path is guided (swings).
- the vibration movement then becomes an orbital movement with a small radius.
- the contact surface of the thread feed wheel interrupted can be divided by several webs, spokes, teeth or pins can be fixed, for example a zigzag Define thread path.
- This embodiment has not only good responsiveness, but also one good laying behavior. This applies largely independently on the type of thread used.
- a particularly user-friendly design results itself if both that upstream of the thread delivery wheel Inlet thread guide element as well as the thread delivery wheel downstream thread guide element from the operating side of the thread delivery device are arranged accessible and both the thread guide of the thread guide lever also the thread travel on the thread delivery wheel on one of the Operating side facing peripheral portion of the thread feed wheel is set. When threading the thread, it must be thus not be passed behind the thread delivery wheel, which makes operation much easier.
- FIG. 1 shows a vibration friction feeder 1 illustrates the total of eight thread delivery routes and thus has eight thread delivery systems 2a to 2h, the are basically the same with each other and to which each have a thread brake 3, a thread guide eyelet 4 Thread guide lever 5, a thread delivery wheel 6 and outlet side Thread guide eyelets 7 belong. To distinguish them are corresponding elements in Figure 1 with letter indices characterized.
- the thread delivery wheels 6a to 6h are of a common one Shaft 8 worn, with which it is connected in a rotationally fixed manner are.
- the shaft 8 is by means of a bearing device contained in a housing 9 rotatably mounted and forms a carrier device for the thread delivery wheel 6.
- the housing 9 also houses an angular gear, the output of which is the shaft 8 and whose input shaft pulleys 11 for driving the Thread delivery wheels 6a to 6h carries.
- the housing 9 is on one Side with a clamping device 12 for fastening the Vibration friction feeder 1 on a thread processing Machine, for example a circular knitting machine or one another knitting machine.
- the pulleys 11 stand like the corresponding pulleys Suppliers engaged with a circumferential belt and are driven by this.
- the thread delivery systems 2 of the vibration friction feeder 1 are among themselves equal.
- the following description of the illustrated in Figure 2 The thread delivery system 2h therefore applies accordingly for all other thread delivery systems 2a, b, c, d, e, f, g, which is why in the following description the letter index are largely left out.
- a brake carrier On an operating side remote from the clamping device 12 of the housing 9 is a brake carrier on the housing 9 14 attached. This carries the thread brake 3.
- You is a disc brake with two brake actuators 15, 16 which sit on a common pin or pin 17.
- the Brake actuators 15, 16 are by means of a compression spring 18, the is supported on a knurled nut 19, preload adjustable are.
- there are other types of brakes like magnetically pre-tensioned brakes, vibration-loaded Brakes, wrap brakes or others that Thread movement-inhibiting devices can be used.
- the brake carrier 14 carries in the immediate vicinity to the thread brake 3, the thread guide eyelet 4, from the starting a thread 21 to be delivered to a further eyelet 22 is performed.
- a further eyelet 22 is performed.
- the eyelet 22 is on one Swivel arm 24 held about a pivot axis 25 is pivotally mounted on the housing 9.
- the swivel arm 24, the connecting rod and the eccentric form a vibration generator 28.
- the pivot axis 25 is indicated parallel to the axis of rotation of the thread delivery wheel 6, that with a dash-dotted line 29 in FIG is indicated.
- the direction of the oscillation movement corresponds about the direction of the running to the yarn feed wheel 6 Thread 21.
- the thread guide eyelet 4 or another wholly or partly with the thread in Touching element. with an electrical, electromagnetic or mechanical vibration generator be connected who works continuously or as needed.
- vibration of the eye 22 or Vibration of the eyelet 4 is the thread between the thread brake 3 and the thread feed wheel 6 vibrated.
- the yarn feed wheel 6 can in principle be of any design his. E.g. it can be disc-shaped Be formed drum, on the outer periphery of a corresponding Covering, such as a plastic or rubber covering is provided. However, a spoke wheel is preferred Illustrated in sections and somewhat simplified in Figure 5a is.
- This thread delivery wheel 6 has on his Outer circumference a circumferential and groove-like depression on, in which webs 31, 32 are arranged alternately are that cross each other in the circumferential direction.
- the Ridges 31, 32 are essentially in the radial direction, however inclined to the axis of rotation and at a distance from each other arranged. Touch adjacent webs 31, 32 not and form an angle with each other. This angle is preferably an acute angle, independently of which follows the one resting on the thread delivery wheel 8 Thread 21 a zigzag path.
- the pens or Crosspieces 31, 32 place a contact surface that is interrupted several times 38 for the thread 21 firmly.
- the thread 21 is also passed through an eye 33 at the free end of the thread guide lever 5 is classified.
- the eye 33 or one other thread guide element carried by the thread guide lever 5 is at some radial distance from the axis of rotation 29 of the yarn feed wheel 6, wherein the radial distance by pivoting the thread guide lever 5 is changeable or adjustable.
- the thread guide lever 5 is, as in particular FIG. 5 shows that it can be pivoted about a pivot axis 35 stored parallel to the axis of rotation 29 of the yarn feed wheel 6 is aligned.
- Spring mechanism 36 tensions the thread guide lever 5 to a position in which its eyelet 33 is as wide as possible is removed from the thread delivery wheel 6.
- the spring force is Dimensioned so that the thread 21 on the thread guide lever 5 the thread delivery wheel can pull when he from the Knitting machine is pulled.
- the spring force and / or the swivel path of the thread guide lever 5 adjustable.
- the further thread travel is after the thread delivery wheel 6 through the thread guide eyelet 7 and possibly further thread guide eyelets 37a, 37b determined through which the thread 21 is guided is.
- a backstop is formed, to which a pivoted parking lever 40 and a brake element 43 which is in a flat, in an acute angle against the thread V-shaped notch.
- the parking lever is on next to the braking element with a hook-shaped, from which Housing 9 protruding end on the thread 21. Its other End is placed in the housing and a shutdown contact K assigned. If the parking lever touches the parking contact K, the machine is turned off.
- the braking element 43 is e.g. in the immediate vicinity to the thread guide eyelet 37a so that the between the thread guide eyes 37a, 37b tight thread 21 runs through the V-shaped incision without touching it. Is the thread 21 between the thread guide eyelets 37a, 37b no longer held taut, the parking lever drops 40 something down and pushes the thread 21 in the V-shaped incision of the braking element 43. This will the thread 21 is pinched and prevented from running back. However the parking lever 40 receives no contact with the Contact K. The machine is not switched off. The switch only responds when the parking lever 40 completely sinks down, what with completely relaxed thread or at broken thread is the case.
- the vibration friction feeder described so far 1 works as follows:
- the pulleys 11 In operation, one turns with at least one of the pulleys 11 meshing rotating toothed belt the pulley 11 in question and thus drives on not further illustrated transmission with the shaft 8 the thread delivery wheels 6.
- the thread 21 is between the Brake actuators 15, 16 of the thread brake 3 are carried out and runs through the thread guide eyelet 4 to the eyelet 22.
- the vibration friction feeder 1 downstream thread processing machine i.e. e.g. one Knitting machine, thread needed and thus from the thread guide eyelet 37b thread 21 running to the machine holds tight.
- the thread 21 is thus interrupted several times Contact surface 38 of the yarn feed wheel 6 in System and thus held in engagement with the yarn feed wheel 6.
- the eye 33 is below one in FIG.
- the Thread 21 is about a wrap angle of about 270 ° with the thread feed wheel 6 in engagement.
- the thread guide lever 5 is comparatively of the thread 21 against the weaker force of the spring mechanism 36 (only schematically indicated in Figure 5) held so that the Eye 33 is close to the circumference of the thread delivery wheel 6.
- the thread delivery wheel delivers 6 initially a little more thread than through the thread guide eyes 7 and the thread guide eyes 36, 37 too the machine is running.
- the thread guide lever 5 can thereby swing out under the tension of its biasing spring and the thread 21, as illustrated in FIG. 3, from the thread delivery wheel 6 take off.
- the wrap angle of the thread 21 decreases significantly on the thread delivery wheel 6. Still can For example, a small amount of thread is supplied by friction locking become.
- the thread 21 touches the thread feed wheel 6 before going to the eye 33 of the thread guide lever 5 running. From this the thread 21 reaches the thread guide eyelet 7 essentially without touching the thread feed wheel 6.
- the thread processing machine continues to take no or too little thread 21, the thread guide lever 5 swing out further and the eye 33 further from the thread delivery wheel 6 and remove its axis of rotation 29, in particular emerges from Figure 4.
- the eye 33 is then in a position in which the thread 21 from the eyelet 22 to the Eye 33 runs without touching the thread feed wheel 6.
- the promotion of the thread 21 is thus completely stopped and the thread 21 is "laid out”.
- the thread 21 runs over from the eye 33 the thread feed wheel 6 to the thread guide eyelet 7 and through the further thread guide eyes 37a and 37b to the machine.
- the wrap angle on the yarn feed wheel 6 is, however so low that the friction between the thread 21 and the Thread delivery wheel 6 is not sufficient to retighten the thread 21 and thereby the swivel lever 5 to the thread delivery wheel to use. At least as long as the thread 21 is not under tension.
- the eyelet 22 is illustrated by the one shown in FIG Eccentric mechanism (vibration generator 28) in constant Vibration kept. This is particularly important, in particular when thread 21 is laid out, i.e. when abrupt Transition between the operating position according to Figure 2, in the thread 21 is conveyed to the operating position Figure 4, in which no thread is conveyed. Will the thread consumption suddenly stopped on the downstream machine, the thread 21 is initially still on the thread delivery wheel 6 on. As a result of his liability to the thread delivery wheel 6 there may be a certain tendency that the thread delivery wheel 6 the one not removed from the downstream machine Takes thread in the direction of rotation 39, whereby the Thread guide lever 5 prevented from laying out the thread 21 would.
- the vibration of the thread guide eyelet 22 divides however, with the thread 21 and prevents this on the Thread delivery wheel 6 adheres. Therefore, the thread 21 immediately detach from the thread feed wheel 6 when the thread consumption is reduced. In particular, it succeeds with this Measure with relatively low forces on the thread guide lever 5 get along and thus also deliver threads 21, which should only be under low voltage and allowed to. Critical threads can also be processed be otherwise strong for sticking to the thread delivery wheel 6 tend. This also applies to yarn delivery wheels 6, which instead of the structure shown a cylindrical have plastic or rubber coated surface.
- the Vibration of the thread supports the conveying of the thread against the inhibition of the thread brake 3 and thus the laying process.
- the vibration also be introduced into the thread guide lever 5.
- the thread guide lever 5 For this purpose, it is possible, for example, to thread the thread guide lever 5 initially to a fixed articulation point 41 store, the thread guide lever 5 with a bias spring 42 is connected. This can be done on the vibration generator 28 be suspended, which ultimately causes the vibrations get to the eye 33 of the thread guide lever 5. That from the biasing spring 42 and the thread guide lever 5 formed vibratory system can resonate or be matched outside of it.
- the yarn feed wheel 6 on a stationary Storage facility rotatably mounted. Are stationary also the thread guide eyelets 7 and the eyelets 22 are mounted.
- the thread guide lever 5 with vibrations is acted upon.
- the vibration generator in turn is used for this 28, at the hinge point 41 of the thread guide lever attacks.
- the biasing spring 42 is on one fixed suspension point supported.
- the biasing spring 42 can be dispensed with are formed when the thread guide lever 5 itself resilient and not swiveling with the vibration generator 28 is connected. E.g. there may be a rigid connection his. Again, the stimulation of self-resonance the thread guide lever 5 possible. A is also possible Operation outside the natural resonance.
- the eye 33 can the illustrated cases swing in the plane in which the thread 21 runs. In Figures 6 and 7 this would be the Drawing level. If necessary, however, the vibration can also directed transversely to the thread running direction or circularly polarized his. Vibration directions that change over time can also occur surrender. It is essential that the thread 21 is so is subject to vibration that it is not on the thread delivery wheel 6 is liable, but the static friction at least on Detach point is disturbed.
- the oscillation generator 28 can be different be constructed. According to Figure 5 he can by an eccentric arrangement can be formed.
- Figure 10 illustrates an alternative embodiment in which a powered Cam 44 periodically hits a tappet 45, to give it a short stroke.
- the plunger 45 can be biased against the cam 44 by a spring 46.
- the cam 44 can be synchronized with the yarn feed wheel 6, if necessary but also with a larger or smaller one Speed, circulate. It can also do several per revolution Generate strokes if the cam deviates from the representation 10 has several surveys.
- FIG 11 schematically illustrates one such a vibration generator 28, which has a fixed bearing Magnetic coil 47 has.
- Its core 48 is magnetic, for example polarized (north pole N, south pole S) and, for example, by resilient bands or membranes 50, 51 axially displaceable hung up.
- the solenoid 47 with AC voltage applied the armature 48 swings in the direction of in Figure 11 indicated arrow.
- the arrangement can be both tuned to resonance as well as outside of resonance be and for vibrating the individual elements 6 to 9 or 5 serve.
- the Vibration exposure can be permanent or temporary take place periodically.
- a vibration generator is used to generate a torsional vibration 28 set up according to Figure 12. This can serve, for example, as a storage device for a yarn delivery wheel 6.
- the shaft 8 is held in a bearing 52 here is held via an eccentric 53.
- the eccentric 53 is via a further bearing 54 on a stationary bearing holder 55 held.
- a rotation of the eccentric 53 leads Shaft 8 regardless of its own rotation on a circular path, as shown in Figure 12 alongside an arrow 56 is indicated.
- the radius of this orbital movement is preferably relatively small and is in the range a vibration amplitude of about lmm.
- the orbital movement can have a circulation number that of the speed of the thread delivery wheel deviates. To be favoured Circulation numbers that are greater than the speed of the thread delivery wheel 6.
- a vibration friction thread delivery device 1 with Thread guide lever 5 for inserting and removing a thread 21 serves to apply thread guide elements 22, 33, 7 or the application of vibrations to the yarn feed wheel 6 to the layout behavior of the friction feeder 1 to improve.
