Definitions
- the invention relates to a thread delivery device in the preamble of claim 1 specified Art.
- a return movement of the storage drum can be several Have causes.
- One in the feed area of the thread delivery device The provided thread scanner is spring-loaded and can after stopping the storage drum pull back the incoming thread and turn the storage drum back with the thread.
- the threads to be processed are mostly elastic, so that when stopping the storage drum the previously in tapered thread generated tension over the storage drum want to turn the thread back.
- less favorable Circumstances and due to a slowdown of the motor create a counter torque that the storage drum want to turn back.
- the well-known backstop is technically complex, prone to wear and tear can especially when accelerating or at higher speeds cause unwanted vibrations, among other things because the disc has an extremely large diameter and works with a very large lever arm.
- the well-known backstop requires an almost exactly vertical arrangement of the thread delivery device, like they don't in some use cases is observable. Furthermore, structurally complex measures are required to burn the disc at its top To prevent the top wall of the motor contacting end face because the disc covers the top wall at a great distance from the Axis of rotation touches and therefore at high speed considerable friction is to be destroyed ..
- the invention has for its object a yarn delivery device of the type mentioned at the beginning, in which a structural simple, easy-to-assemble backstop provided is reliable, wear-resistant with a long service life works and does not cause vibrations.
- the braking surface can be set to a diameter which can be significantly smaller than the inside diameter of one if applicable, provided storage drum. Shows the rotating element the tendency to move backwards, then it will Locking element relative to the abutment in a smooth-running Rotational movement twisted by the drag force until its counter braking range thanks to the eccentric to the axis of rotation of the rotating element Circle outwards or inwards against the braking surface starts and blocks the return movement.
- the engagement in the blocking position takes place harmoniously and reliably, whereby a high braking power can be generated.
- a high braking power can be generated.
- the locking member when restarting the rotary element easily and forcibly in the correct direction of rotation detaches from the braking surface and returns to the defined one Run position returns.
- the area of engagement between the Locking element and the braking surface can be designed over a large area, so that no excitation to vibrations in the thread delivery device arises.
- the backstop works reliably and with little wear with a long service life.
- the characteristic curve can be predetermined precisely and can be optimally designed with which the backstop takes effect comes or is solved again.
- the backstop is optimal on one made small diameter, and in particular on a Diameter independent of the size of the storage drum.
- the towing force can be exactly according to claim 3 Predetermine the dimension of the spring force. Conveniently it is pressed against the effect of gravity.
- the thread delivery device can therefore be installed in any position use without endangering the backstop. Further can be the area in which the locking member the towing surface contacted, relatively close to the axis of rotation of the rotating element set so that even at high speeds and strong accelerations the risk of burning the Blocking member is avoided, also by the ring shape, the one relatively low specific surface pressure per unit area enables and yet the sufficient towing force guaranteed.
- the embodiment according to claim is particularly expedient 5, where the motor is fixed in the housing and the backstop well encapsulated from the working area of the storage drum is separated, in which dirt and lint are inevitable are. Since the locking member does not work with the Has inside diameter of the storage drum, the Select the diameter of the braking surface small enough to be high Speeds and strong accelerations in modern Thread delivery devices to rule out vibrations.
- the motor shaft over the co-rotating Backstop supported on the housing against a return.
- the backstop makes according to claim 7 Rotary movement of the rotating element does not co-operate, but acts first with a return to the motor shaft over the for example block the braking surface attached to the motor shaft.
- the locking member works with a brake ring together who among other things provides a high braking effect due to the material.
- a brake ring could be placed directly on or in the Locking member can be attached (claim 9).
- a good backstop is also according to claim 10 reached a braking surface that is only structured, for example is knurled.
- This braking surface can be in a metallic Body arranged, for example in the housing or in a housing insert.
- Plastic molded parts are characterized by high Shape accuracy, low weight and low wear out. Because the locking member by precisely adjustable spring force the towing surface is pressed, self-lubricating Plastic grades are used, which is a smooth Ensure rotatability of the locking element even over a long service life.
- the self-lubricating effect has a braking effect with the braking surface no adverse influence because there by the eccentric movement of the locking member a quick-acting forced intervention can be produced anyway.
- the embodiment according to claim 12 is structurally simple and ensures low-wear work even over long periods Service life.
- the projections or the circumferential bead are one Assembly aid for a pre-mintable unit because the The washer does not come off the ring flange under the force of the spring can fall off.
- the ring disk comes into operation normally not to the protrusions or to the peripheral bead.
- a thread delivery device F preferably a thread delivery device F for a knitting machine, has a stationary housing G, on the underside of a storage drum T rotatably mounted which is about an axis of rotation X by means of a motor M in a predetermined direction of rotation to be driven.
- the Motor M can be switched on and off by means of signals, that of a scanning device D in a housing bracket 1 depending on the size of one on the storage drum T formed thread supply (not shown) are generated.
- the fed to the storage drum T by a not shown Supply spool coming thread (not shown) is through stationary Thread eyelets 2 passed and passed through a thread brake 3 under surveillance by a sensing element 5 to the extent the storage drum T.
- An inclined feed element V pushes each turn wound on the storage drum T. in Fig. 1 down, so that a thread supply of several Turns is formed.
- the thread intended for consumption is pulled off over the top of the storage drum.
- a backstop R is provided in the thread delivery device F, namely between an upper cover wall 6 of the housing G and the upper end of a motor shaft H.
- the backstop R contains in the embodiment of Fig. 1 with the motor shaft H rotatably connected abutment W and a relative to it rotatably supported by a weak coil spring 4 upward loaded blocking element S, which is used for cooperation provided with a braking surface B in the top wall 6 Insert 7 is used, namely a return or a Return movement of the storage drum T or the motor shaft H prevent after a standstill.
- the abutment W is an annular body A1 from a hub 8, which has a non-circular inner bore 9 attached to the matching end 10 of the motor shaft H in a rotationally fixed manner is a radial flange 11, which is a spring seat 12 defined, and an axial ring flange 14 with a cylindrical Outer peripheral surface 15, whose axis is opposite to X1 the axis of rotation X of the motor shaft H is eccentric. Further is in the annular flange 14 a cutout limited in the circumferential direction 17 molded, the (Fig. 3) two in the circumferential direction spaced stops 18 and 18 'defined. In the end area a circumferential bead 16 is formed on the ring flange 14.
- Locking member S that which is mounted on the abutment W relatively rotatably to this Locking member S is also an annular body A2, namely an annular disc 19 with an inner bore 20 and one cylindrical outer circumference 21, which is used for cooperation with the Braking area B is determined.
- the central axis of the peripheral surface 21 is correct in the running position of the backstop R with the axis of rotation X at least approximately.
- the annular disc 19 In one face the annular disc 19 is concentric with the peripheral surface 21 Spring receiving groove 13 formed for the coil spring 4, the other end in the spring seat 12 of the Flange 11 supports and the annular disc 19 with at least a part 22 of its other end face against a housing-fixed Drag surface 23 presses.
- a nose 26 In the inner bore 20 the annular disc 19 a nose 26 protrudes inwards, 4 stops 27 and 27 'defined with the Stops 18 and 18 'for setting a running position and cooperate in a locked position.
- the braking surface B and the Trailing surface 23 are included in the insert 7, which in the Cover wall 6 is set. It is conceivable the tow surface 23 and to arrange the braking surface 21 directly in the top wall 6.
- the braking surface B is on one Brake ring 24 made of a frictional material, such as rubber, elastomer or another plastic, provided in a Version 25 of insert 7 is set.
- a radial Game Y provided in the in Fig. 2 shown running position, in which the backstop R the normal rotation of the motor shaft H is not affected the peripheral surface 21 and the braking surface B a radial Game Y provided.
- the two ring bodies A1, A2 are expediently plastic parts, for example injection molded parts.
- the insert 7 can consist of metal, for example steel.
- the braking surface B could also be directly from the inner peripheral surface of the socket 25 are formed, which then expediently a roughened Surface structure, for example knurling, has.
- the peripheral surface 21 could, if necessary, be structured to increase the frictional engagement.
- the locking member S sits in accordance with FIG the rotational position shown in FIG. 4 on the ring flange 14 of the abutment W, which is in the rotational position shown in Fig. 3 located.
- the nose 26 is at the stop 27 ' Stop 18 'on.
- the peripheral surface 21 is then essentially concentric to the axis of rotation X and is the braking surface B (Fig. 2) with the radial play Y opposite. 3 and 4 counterclockwise motor shaft H takes the locking member S over the abutment w without it the braking surface B comes into contact. Because of the pressure the spring 8 becomes the locking member S against the drag surface 23 pressed so that a permanent Towing force in the locking element S acts in a clockwise direction stops with the stop 27 'at the stop 18'.
- a kinematic reversal is conceivable in such a way that the Ring body A2 on the top wall 6 or in the insert 7 rotatably is mounted, however, the ring body A1, the motor shaft H or the end 10 (which then has a cylindrical outer circumference has) rotatably comprises, expediently again with a radial play.
