Definitions
- the invention relates to a yarn delivery device of the type specified in the preamble of claim 1
- thread delivery devices with adjustable thread separation and a backstop for the winding element are known.
- Such thread delivery devices are mainly used for processing special thread material, for example for delivering the weft thread when weaving paper or cardboard filter or shaped fabrics due to the elasticity or Stiffness of the thread material or due to certain mechanical conditions, when the winding element is stopped, there can be a tendency for the winding element to turn back against the winding direction. This can lead to loop formation in the thread or to overlapping of the thread windings on the storage drum and thus to malfunctions.
- the backstop between the motor housing and This undesired backward movement of the winding element prevents the drive shaft or in the support bearing of the support rod cage.
- the thread separation ie, the spacing between two adjacent threads Windings on the storage drum is a measure that is extremely important for thread control in the case of a special thread material, since the dimension of the thread separation (pitch) is not the same for all thread sources and types of thread, but for each thread type or each thread material is individually dependent on different factors
- the amount of thread separation is adjusted in order to create optimal conditions for the thread being processed.
- the thread separation results from a feed movement applied to the thread windings on the storage drum in the direction of the withdrawal end of the storage drum. It is a common principle for the drive shaft in the feed rod cage to be eccentric and to rotate the inclined cylinder, which generates tilting movements on the feed rod cage rotatably mounted on the cylinder of the stationary storage drum.
- the rods of the feed rod cage move relative to the bars ben of the support rod cage, movements from the winding side of the thread outwards over the support rod drum, move forward before they step back behind the support rod support cage, reverse their movement and return to the starting position yarn separation to adjust either the radial plane of the maximum eccentricity relative to the plane of the inclined position of the cylinder about the axis of the drive shaft in order to change the phase shift between these two radial planes, or for a given phase shift the inclined position is changed in the first, technically simpler A bush carrying the inclined cylinder surface is turned away on an eccentric element arranged on or formed on the drive shaft.
- the bush is held from the outside and the male shaft is rotated with the help of the winding element in one or the other direction of rotation.
- the backstop only allows the counter shaft to rotate in one direction of rotation, namely the winding direction. For this reason, an adjustment of the fade separation in the blocked direction of rotation by simply rotating the drive shaft by means of the winding element cannot be carried out
- the invention has for its object to provide a Fade ⁇ Railgerat of the type mentioned, in which, despite the backstop, the thread separation can be enlarged and reduced in each direction of rotation by simply rotating the drive shaft
- the backstop still prevents the unwanted jerk rotation of the take-up element, since the drive shaft is supported in the backward rotation direction via the backstop and the feed rod cage on the stationary storage drum. Accordingly, the desired safety effect of the backstop is given. If the drive shaft is rotated in one or the other direction of rotation, it must be held in a rod-like manner, the locking effect of the backstop in the reverse rotation direction can be used if necessary in order to make the relative rotation between the levels of the inclined position and the eccentricity.
- the backstop is arranged in the feed storage in a structurally simple and space-saving manner
- the backstop can be equipped with locking elements that automatically engage only during or before an inadmissible rotary movement, similar to the freewheel of a bicycle drive hub.As a result, the backstop can act as a self-locking rotating freewheel in one direction of rotation or as one in this direction of rotation blocking overtaking rotary coupling be formed
- the backstop can also be provided between the feed bearing and the drive shaft so that the feed bearing is supported by the backstop on the drive shaft or the adjustable element of the thread separation mechanism
- the backstop can be arranged parallel to and next to the feed bracket.
- the locking action is used up between the rings or bearing surfaces or directly between the element which can be rotated on the drive shaft and the feed rod cage
- the eccentric axis and the inclined axis can be adjusted relative to one another and / or relative to the axis of the drive shaft
- the eccentric axis and the inclined axis are shown in relation to each other Rotation of the drive shaft adjusted in every direction of rotation It is expedient to integrate the eccentric axis in the drive shaft and to have the inclined axis constituted by an element which is separate from the drive shaft and is arranged on it in such a way that it can be rotated
- the bearing surfaces could even be arranged obliquely or eccentrically with respect to the axis of the drive shaft.
- the inner bearing shell then formed the element for the adjustment of the thread separation, which element can be rotated relative to the drive shaft
- phase shift between the inclined position and the eccentricity is changed by the relative rotation adjustment, which results in an enlargement or reduction or even complete elimination of the thread separation
- a bushing is arranged in the thread separation adjustment mechanism as a rotatable element on a supporting surface of the drive shaft in such a way that for adjusting the thread separation, the bushing is rotated on the drive shaft and can be fixed in the respectively desired position.
- the supporting surface on the drive shaft or the contact surface on the socket must be eccentric. The other of the two surfaces is then inclined
- the feed bearing is expediently arranged on the bush in a rotationally fixed manner and a rotary lock receptacle is provided, on which an adjustment tool can engage in order to hold the bush in order to adjust the thread separation when the drive shaft is rotated relative to the bush by means of the winding element
- Comfortable and easy handling is achieved with an adjustable friction clutch between the bushing and the drive shaft.
- the frictional engagement of the friction clutch only needs to be strong enough to ensure that the bushing is reliably carried along when the anti-friction shaft rotates and that the jerk-blocking force does not overcome the frictional engagement
- For a stable mounting of the feed rod cage at least two axially spaced roller or slide bearings are provided. However, the backstop only needs to be arranged in one of these bearings.However, if this is considered appropriate, all bearings of the feed storage could also be equipped with backstops
- the adjustment tool can be a pin that can be adjusted in the front end of the storage drum between an engagement position in the rotary lock receptacle and a passive position. If the pin is loaded into the passive position by spring loading, for example, the adjustment process is simple because the The pen needs to be pressed against the spring force in the original position before the drive shaft is rotated accordingly, and then the pen automatically returns to the passive position under the spring force
- a stop device In order to prevent a too wide adjustment, a stop device should be provided which limits the relative rotational adjustment stroke of the bush on the drive shaft
- FIG. 1 shows a longitudinal section through components of a thread delivery device essential for the invention with adjustable thread separation and backstop
- a thread delivery device F in FIG. 1 has a motor housing 1, in which an electric motor 2 is arranged, which drives a drive shaft W about an axis X in a direction of rotation.
- a winding element 3 is attached to the drive shaft W, for example as a winding tube, which is inclined strives outwards from the drive shaft W, which is hollow there, and ends outside the motor housing 1.
- the winding element 3 is incorporated here into a so-called winding disk 4, which is carried by the drive shaft W and is located between the motor housing 1 and a drive shaft W on the motor Home 1 supported storage drum 6 is located
- the drive shaft W acts as a carrier of the storage drum 6 and has a coaxial extension 5 for this purpose
- the storage drum 6 is composed of two interlocking rod cages, namely a support rod cage 7 with axial rods 8 spaced apart in circumferential direction, and a feed rod cage 28 with axial rods 9 lying in the spaces between the rods 8.
- the support rod cage 7 has a stationary front end 24 and is arranged on a hub 10 which is rotatably mounted on the extension 5 with a support bearing 11 coaxial with the axis X of the drive shaft W (eg two roller bearings)
- cooperating permanent magnets 12, 13 are provided in the motor housing 1 and in the hub 10, as is known per se
- the rod 9 of the feed rod cage 28 are attached to a common hub 14 which is rotatably supported on a bushing B arranged on the drive shaft W by means of an inclined feed bearing 15 which is eccentric to the axis X of the drive shaft W.
- the bushing B is seated on a with respect to the axis X, eccentric, cylindrical bearing surface 16 which is formed on the extension 5 or is formed by a member (not shown) attached there.
- the eccentric axis X1 of the bearing surface 16 is spaced from the axis X by a dimension e.
- cylindrical support surface 17 is inclined with respect to the axes X and X1 (indicated by the dash-dot inclined axis X2)
- the eccentric axis X1 and the oblique axis X2 are indicated lying in the plane of the drawing.
- a phase displacement in rotation of the drive shaft W may be provided.
- a friction clutch R is provided, for example in the form of a spring end acting on the free end of the socket B Fede ⁇ akets 19 which is biased by a set screw inserted into the recessed free end of the drive shaft W and the socket B with a predetermined rotational resistance couples with the drive shaft W
- a rotary lock receptacle 21 is provided in the feed bearing 15, for example on an annular flange 20 which, for example, can be connected in a rotationally fixed manner to the bushing B.
- the feed bearing 15 in the embodiment shown consists of two axially spaced roller bearings, one of which the roller bearing 29 facing the free end of the drive shaft W is equipped with a backstop D.
- the roller bearing 29 has an inner ring 25 and an outer ring 26 and rolling elements 27 arranged therebetween.
- the backstop D is also effectively integrated between the inner ring and the outer ring 25, 26 could the feed bearing 15 have one or two plain bearings with interacting sliding surfaces
- the backstop D is in the feed bearing 15 Integrated It is conceivable to incorporate the backstop in the left-hand roller bearing in FIG. 1 or even to equip both roller bearings with a backstop. It is also possible to provide the backstop D between the inner ring 25 and the bushing B, or parallel to the respective bearing next to it
- a stop device 30 is provided between the bushing B and the drive shaft W for limiting the rotational stroke of the bushing B relative to the drive shaft W.
- the unwinding element 3 brings the yarn Y onto the storage drum 6 due to the inclined and exaggerated rotation of the drive shaft.
- ⁇ sche bearing surface 17 of the bushing B the inner ring 25 performs a rotating wobble movement. Since the stationary support rod cage 7 is prevented from rotating with the drive shaft W via the permanent magnets 12, 13, the rods 8 and 9, which are supported against one another, also provide the feed Rod cage prevented from rotating between the inner ring 25 and the outer ring 26, a rotational movement takes place in only one direction of rotation, whereby tilting movements from the wobbling movement of the inner ring 25 are transmitted to the rod 9, which cause the advancement of the thread windings and the set thread separation Z.
- the backstop D couples the inner ring 25 to the outer ring 26 and supports the drive shaft W in this impermissible direction of rotation Hub 14 of the feed rod cage 28 ab A return movement does not occur
- the thread separation Z is to be adjusted, ie enlarged, reduced or completely eliminated, then when the electric motor 2 is stopped, the tool 22 is inserted into the rotary lock receptacle 21 by rotating the disk 4 and simultaneously pressing a push button on the front.
- the drive shaft W or the disk 4 can no longer be turned only after the frictional resistance of the friction clutch R has been overcome, the wing 16 with the drive shaft W rotates within the bushing B, which is locked by the tool 22, within the stop device 30 predetermined turning strokes, the respectively desired setting of the thread separation Z can be sought.
- the return spring returns the tool 22 to the passive position shown, possibly supported by an l easy rotation of the disc 4 in one or the other direction of rotation. Then the thread delivery device is functional again
- an adjustment tool could also be provided from the outside between the interlocking rods 8 9 or through one of the rods are then inserted into a modified rotary lock receptacle 21 in order to hold the bushing B otherwise, the backstop D acts in a direction of rotation of the drive shaft W parallel to the adjusting tool 22. This means that the backstop D in this direction of rotation also fixes the bushing B on the feed Rod cage 28 and thus supported on the storage drum 6 If only an adjustment of the thread separation Z is required, which requires a rotary movement of the shaft W in the reverse rotation which is locked per se, then the adjustment tool 22 does not need to be actuated at all. This adjustment can be done under Utilization of the blocking effect of the backstop D can be carried out
