The yarn delivery apparatus being characterized in that the floatingly mounted delivery roller is configured as a rotationally symmetrical hollow body whose inner wall is supported on a ball-shaped support body which is secured to an axial shaft in a manner such that the position of the floatingly mounted delivery roller can be changed only within a plane defined by the axes of the two delivery rollers.
Description
The present invention relates to a kind of yarn-feeding device that has two conveying rollers, one of them roller flexibly leans against on another roller, can regulate, and at this, a roller in two rollers is to float to install, so that this roller can wave or swing with respect to another roller.
In the sort of yarn-feeding device of for example describing in DE-OS2658995, at least one roller in two conveying rollers is from the external drive rotation, and another does not then drive by the yarn that sent roll gap from the roller of external drive and is not rotated.Two rollers are parallel to each other, and at this, for an one thread is inserted in the yarn-feeding device, in two rollers one can or move usually or swingingly leaves another roller, and readjust after inserting yarn and come on another roller.In this known yarn-feeding device, in the operational process of yarn-feeding device, the distance between two rollers is decided by the thickness of yarn of the yarn that passes basically, and at this, under perfect condition, this distance should be constant on the whole length of roller.In order to improve the axially parallel degree between two rollers, in the yarn-feeding device of describing in DE-OS2658995, a roller in two rollers is installed on the spring-loaded rocking arm, this rocking arm be designed to from centering, can be around the swing arm form of a swivel point swing.In addition, as departure point,, be applied to the clamping pressure for the treatment of on the delivered yarn and become very even and realized that therefore uniform yarn carries by improving the axially parallel degree.
The problem of the present invention to be occurred, said problem is to occur when machine is carried two yarns with different thicknesses or fiber number simultaneously by yarn-feeding device, for example in order to produce flame, because roll gap is to adjust by the thickness of thicker yarn, therefore thinner yarn is not subjected to the effect of roller.
Equally, when the yarn of two or many same thicknesses passes yarn-feeding device, when for example in the yarn that passes, having one to have an instantaneous yarn slubbing, distance between two rollers then may become greatly accordingly with this yarn slubbing, and its result will make another one thread no longer contact with the surface of two rollers.May occur skidding thus and therefore make that the conveying of two one threads or yarn line segment is no longer even.On the other hand, when the one thread in two one threads has a yarn constriction with respect to another one thread, yarn or yarn line segment that this root has the yarn constriction will pass between two rollers no longer non-skidly, because thickness according to another one thread or yarn line segment, distance between two rollers may not change, in other words, also may diminish.
Because in the yarn-feeding device of in DE-OS2658995, describing, the rocking arm that supports one of them roller be designed to from centering, can be around the swing arm form of a swivel point swing, therefore, this known yarn-feeding device is carried at the same time under the two one thread situations and can be addressed the above problem, even just use this known yarn-feeding device itself, two axially parallel degree between the roller are improved.
The shortcoming of this known yarn-feeding device is, a sizable system swingingly be suspended around a swivel point,, except roller, is supporting this roller in addition and with spring-loaded rocking arm that is.
Task of the present invention is, a kind of comparatively simple by contrast yarn-feeding device is provided, be used for carrying simultaneously two one threads, in this device, can not be subjected to different thicknesses or the yarn slubbing of fiber number or appearance or the influence of yarn constriction of two one threads, under any circumstance can both guarantee evenly and non-skidly two one threads or yarn line segment to be carried.
For finishing above-mentioned task, yarn-feeding device of the present invention is characterised in that, the roller of installing that floats is designed to rotational symmetric hollow body, this hollow body with its inwall be bearing in one be fixed on the axle, on the cydariform supporting mass, its mode is that the position that roller is installed of floating can only be changed in a plane of being determined by the axle of two rollers.
Because this roller just floats and installs, therefore this roller is not subjected to too high force of inertia, it produces in the time of can having an one thread yarn slubbing or yarn constriction to occur in two yarns that pass yarn-feeding device, make the thrust that affacts on two one threads that pass yarn-feeding device keep constant like this, therefore can carry two one thread line segments non-slip and equably by yarn-feeding device.
The supporting mass that is installed on the stationary axle is preferably spherical.
The direction superior displacement of the conveying roller of installing in order to prevent to float outside a plane of determining by the axle of two rollers, according to a kind of preferred form of implementation, said yarn-feeding device is characterised in that to have the block that abuts on the dancer, said block is parallel to the plane that constitutes of axle by two rollers on the one hand, on the other hand then perpendicular to the roll gap of yarn-feeding device.
Particularly advantageously be, can also be used for one as EP0701014B1 (=US-PS5 according to yarn-feeding device of the present invention, 626,011) in the described system, related situation be the integrated OE-spinning that doubled yarn is extracted out of the spindle hollow shaft by the two-for-one twisting spindle-and two-for-one twisting-process in the first process of spinning, with spin at the beginning of two-spinning yarn is transported in the OE spinning rotor simultaneously.
Below will the present invention will be described in detail by accompanying drawing:
Fig. 1 is the transparent view of first kind of form of implementation of yarn-feeding device of the present invention;
Fig. 2 is the transparent view of second kind of form of implementation of the bearing arrangement of a roller in two conveying rollers.
According to Fig. 1, yarn-feeding device is made up of two conveying rollers 1 and 2, and wherein conveying roller 1 is installed on the spring-loading rocking arm 10, like this, in order to insert yarn A and B, it can leave conveying roller 2 outside swings and readjust after inserting yarn and come on the roller 2.For example an end of a tension spring 11 is fixed on the rocking arm 10, and the other end of this tension spring 11 then is fixed on the fixed part (not shown) of yarn-feeding device for example or frame.
According to Fig. 2, roller 2 is designed to hollow body, and this hollow body is bearing in its inwall on the cydariform supporting mass 12 that is fixed on the stationary axle 3, and it is spherical that this cydariform supporting mass is preferably.On the opposed end of roller 2, block 13,14 abut on the outer circumference surface of roller 2 or abut in roller 2 with the concentric shaft shoulder 2.1 of outer circumference surface on, the orientation of said block is parallel to the plane that constitutes of axle by two rollers 1,2 on the one hand, on the other hand then perpendicular to the roll gap of yarn-feeding device.This mode can guarantee that roller 2 can only change its position around an axle in a plane of being determined by the axle of two rollers 1,2, block 13,14 by abutting in roller 2 upsides simultaneously, can avoid roller 2 to swing or upset around horizontal shaft in a plane, said plane and two rollers 1,2 are tangent in the contacted case surface in roll gap zone.
When having an one thread yarn slubbing or yarn constriction to occur among two one threads that pass conveying roller or yarn line segment A and the B, said roller 2 can be offset according to yarn slubbing that is occurred or yarn constriction, so roller 2 has occurred and slubbing or the corresponding inclination of constriction with respect to roller 1.Therefore said roll gap becomes big or dwindles on the zone of yarn line segment A, roll gap then keeps its original size according to the thickness of yarn of this yarn line segment B on the zone of yarn line segment B.This mode has guaranteed to keep constant by the thrust that roller 1 and 2 is applied on two one thread line segment A and the B, thereby the assurance conveying roller can evenly and non-skidly be carried two one thread line segment A and B.
According to Fig. 1, a roller in two rollers, preferably roller 1, can be driven by a motor 12 that is fixed on equally on the rocking arm 10.As clearly shown in Figure 2, the transmission of two rollers also can be carried out by this way,, applies pulling force on one in two one thread line segment A and B that is, thereby drive two relative rotations with 2 of roller 1, another one thread line segment then correspondingly is transferred thereupon together.
