Description

The The invention relates to a plastic disk separator for ring spinning machines with wear-resistant Reinforcing at least its leading edge.

The Most ring spinning machines are equipped with disc separators, in the amount the cops over the ringbanks are arranged between the spindles. You have the tasks, one Touch The sometimes wide-opening thread balloons adjacent Spinning points and the spinning of the ends of broken threads in adjacent To prevent thread balloons. This would lead to thread breaks lead these adjacent thread balloons, which grow into rows thread breaks can.

Disc separators are usually made of plastic today. After a thread break is often the thread end on the cop on the front or trailing edge of the Disc separator flung and while turning the cop over this Edge pulled. It would especially threads made of synthetic material in the plastic edges of Scheibenseparatoren cut and damage them. Such damages are suitable to catch flight or cut thread scraps and can in turn cause further thread breakages.

Around It is already known to prevent this (JP Publ. No. 10204732 A), the front and Trailing edges made of plastic disc separators with protective sleeves made of metal. The edges are beaded for this purpose thickened. On these beads become slotted metal sleeves postponed, which are held on this due to their elasticity.

These Arrangement requires close tolerances between the beads and the metal sleeves and elastic metal sleeves. They also require straight edges on which the sleeves are pushed can and thus narrow the possibilities optimally Shaping for the disk separators.

In U.S. Patent 1,833,023 is a wire-shaped, horizontal one Ring separator disclosed on perpendicular disc separators is plugged. However, he can not serve the leading edge a disc separator from damage by hurling thread ends to protect.

The US Patent No. 1,817,143 shows disc separators of minimum thickness, which the arms that she uses with her back and bottom are fixed, strengthened become. Because these arms are not on the leading edge of the disc separators they are not capable of damaging them preserve.

Also U.S. Patent 2,265,410 apparently discloses a disk separator thin Sheet metal whose trailing edge is rolled up to stiffen it. There If this curling refers to the trailing edge, this measure is not suitable to protect the front edge against damage.

The GB-PS 866,180 has disc separators made of transparent material to the object, which are provided at its periphery with a bead. These Bead serves to clamp the disk separators in holder and to hold. Because these bulges out the same transparent (plastic) material as the disc separators, they are also not suitable, this against damage by hurling thread ends to protect.

Of the The invention was therefore the task of an effective Scheibenseparator to create with an edge protection, which does not have particularly high requirements concerning the accuracy of fit and the most easily attachable and interchangeable. This task is performed by a disk separator according to claim 1, 2 or 3 solved. All these disc separators share the common idea of having a deflector bar the edge of the disc separator is arranged. This can do this Edge shaped arbitrarily, in particular be bent. The in claims 1 and 2 proposed clip fasteners or proposed in claim 3 plug-in fastening of the rejection bar at the Scheibenseparator facilitates its replacement when worn or Damage.

In the figures of the drawing are embodiments of the invention shown schematically. Show it

1 the perspective view of a first embodiment;

2 a second embodiment in illustration as in 1 ;

3 and 4 two further embodiments in illustration as in the 1 and 2 ;

5 a variant of the embodiment according to 4 , partial;

6 a cross section in plane AA the 4 ,

In the figures is a disc separator 1 represented, its area 2 at a part of its front edge 3 , its bottom edge 4 and its trailing edge 5 through beads 6 is reinforced. In his back Be rich the disk separator runs in a loop-shaped holder 7 from, by means of which it can be clamped on a holding rod, not shown.

In the embodiment of the 1 and 2 is the disk separator 1 on a part of its leading edge 3 a deflector 8th assigned, consisting of two parallel branches 9 and 10 made of metal wire, in particular of steel wire. The two branches 9 . 10 of the wire hanger are over an eyelet 11 connected to each other on a pin 12 on the lower edge 4 of the disc separator 1 is aufgeklippst. From there, the two branches extend along the front edge 3 the disc separator up, where they both eyelets again 13 mold with which they tap 14 embrace that of the opposite sides of the surface 2 protrude the Scheibenseparators.

The pin 12 also serves as a support for the disc separator 1 on the ring rail, thus ensuring the correct position of the disc separator.

After clipping the eyelet 11 on the cones 12 and the eyelets 13 on the cones 14 is the deflector 8th fixed on the disc separator. The pins can be provided with flat terminal beads which the eyelets 11 respectively. 13 holders. The deflector can be easily removed from the pins 12 and 14 abgeklippst and exchanged for another.

In the embodiment of the 2 is the deflector 8th shaped so that it is a short distance from the front edge 3 of the disc separator 1 stands.

How out 3 can be seen, the deflector 8th' also consist of a simple wire hanger, in holes 15 . 16 in the beads 6 the leading edge 3 or / and the bottom edge 4 of the disc separator 1 is pluggable. Even such a Abweisbügel with only one branch may alternatively have eyelets, by means of which he on pin of Scheibenseparators 1 is aufklippsbar.

In 4 an embodiment is shown in which the Abweisbügel 8th'' consists of a corresponding bent sheet metal strip, which at its lower end in an open or closed eyelet 11 ' leaking, by means of which he on the cones 12 is aufklippsbar. At its upper end it has a curl 17 from the side into a recess 18 in the bead 6 the leading edge 3 of the disc separator 1 is pluggable.

In the in 5 and 6 illustrated embodiment has made of sheet metal Abweisbügel 8th'' of the 4 at its lower end and in its upper part retaining clips 19 by means of which he puts on a bead 6 of the disc separator 1 is aufklippsbar.

Although not shown in detail, can also be the trailing edge 5 of the disc separator 1 be provided with a deflector.
