Definitions
- the invention relates to a rotating body with a lateral surface and end faces and a Use for that.
- Such a rotating body is known for example from DE 25 08 567 and in particular as a rotating tube for the generation of so-called false twist in a device for Texturing of textile games known.
- the gam runs through the rotating tube in its Longitudinal direction, but is about a dome arranged approximately in the middle of the tube led around. If you turn the rotating tube, the game will be rotated. To thread or insert the chamfer before texturing, the gam must be on one End face of the rotating tube inserted into an axial hole, looped once around the dome and run again.
- the invention as characterized in the claims, therefore achieves the object to create a rotating body into which a test specimen or elongated product is very can be easily inserted, which can also be used for automated insertion of the test specimen or product and with which a high-grade swirl can be given.
- the task is solved with a rotating body that has a groove for the test body or the elongated product to be processed, which is subsequently for the sake of simplicity is always referred to as a test specimen, into which the test specimen is inserted from the outside can be.
- the deflection of the test body from the longitudinal axis of the rotating body happens either through the design of the groove itself, or through specially provided Elements such as pins, webs, drivers, etc.
- the groove is preferably against the The lateral surface and the end faces open and has a variable, in the area of End faces greater and less deep in the area of the lateral surface.
- Fig. 1 shows the rotating body 1 with its cylindrical outer surface 2 here and flat end faces 3 and 4.
- a groove 5, 6 can be seen here from its open side. It stretches from the end face 3 to the end face 4.
- One can also see a test specimen 7 and one Longitudinal axis 8 for the rotating body 1.
- the lateral surface 2 has in the region of the end surface 3, 4 a distance 21 from the longitudinal axis 8, which is greater than a distance 20, as in a section 22 further away from the end faces 3 and 4 can be measured. This creates 2 shoulders 29 and 30 on the lateral surface.
- Fig. 2 shows the same rotating body 1 from a direction that in comparison to the direction Fig. 1 is rotated by 90 °.
- the groove 6 is bounded here laterally by levels 9 and 10 and the groove 5 by levels 11 and 12
- the levels 9 and 10 are at an angle 13 and the levels 11 and 12 inclined by an angle 14 against the end faces 4 and 3, these planes 9 to 12 also inclined against the lateral surface 2 and close an angle with it, for example 15 a.
- the line 16 here is a plane of symmetry of the rotating body 1 represents, so you can see here that the levels 9, 10, 11 and 12, the end faces 4, 3 in Cut areas of this plane of symmetry 16.
- groove 3 again shows the rotating body 1 in a perspective view.
- the groove here the groove 6 is in the area of the end face 4 to the area of Longitudinal axis 8 into the rotating body 1, or even beyond, extends or extend can.
- the groove 6 in a region 17 of the lateral surface 2, the groove 6 is not very deep, what This shows that a side wall 18 of the groove 6 has a very low height.
- the In this area 17, groove 6 also merges into groove 5, which here in particular has a Web 19 happens, which here is part of the groove 5, 6 but is the actual means of deflection of the test specimen forms in the area 17, the grooves 5 and 6 are slightly offset from each other
- Fig. 4 shows the rotary body 1 from another side, from which a further third and fourth groove 23, 24 can be seen. These are arranged symmetrically to the grooves 5 and 6 and serve to avoid unbalance, i.e. mass balancing. It is clear that the Rotary body can also be balanced by other means, so that the grooves 23, 24th are not necessary.
- FIG. 5 shows a device 25 for supporting and driving the rotating body 1 in particular two friction wheels or friction wheel pairs 26 and 27 with a drive 28.
- the Rotary body 1 rests on the friction wheel pairs 26, 27 and is then over the shoulders 29, 30 centered in its longitudinal direction.
- the rotating body 1 is passed through transversely to the longitudinal direction Magnets 31, 32 pressed onto the friction wheel pairs 26, 27.
- magnets 31, 32 instead of using a magnet, could the rotating body but also by a third pair of wheels, not shown here, or another Means are pressed onto the friction wheel pairs 26, 27.
- the aforementioned rotation of the test body 7 before entering the rotating body can at continuous measurement of properties of the test specimen may be desirable. Therefore can such rotating bodies not only when processing filaments, for example, but also when measuring filaments, yarns and other longitudinally moving test specimens be used.
- the rotating body 1 can thus for measuring purposes and for processing of yarns, filaments, etc.
- Fig. 6 shows a basic body 35 for a rotating body, which is also suitable for between the friction wheel pairs 23, 24 of the device according to FIG. 5. there the friction wheel pairs would possibly have to be at a greater distance since they are on Shoulders 36, 37 of the rotating body would have to attack. Although not shown here, points also this base body 35 has a groove that upgrades it to the rotating body.
- this means 49 can consist in that the base 50 of the groove 48 extends from a point 51 in the area of the lateral surface 54 deepened towards the end faces 52, 53 and thus the test material against the outer surface 54 deflects.
- Fig. 13 in turn shows a straight, only groove 61 and Fig. 14 shows the same groove in one Chicane 62 is installed. Since the groove 61 does not reach the center here, the test material deflected along the entire length of the groove 61 and rotated by the rotation of the rotating body.
- FIG. 15 shows a spiral groove 63 and FIG. 16 shows an arcuate groove 64.
- the two grooves 63, 64 extend to the center, so that the mode of operation of the 13 and 14 corresponds to the rotating body.
- FIG. 17 shows a further embodiment of a rotating body 65 with two short grooves 66, 67 as well as with an optional driver 68 for the test material. Because the shape of the Grooves 66, 67 is not such that the test material on the end faces 70 in the region of the axis 69 is held, the known axially arranged rings 71, 72 are provided.
- the rotating bodies shown are suitable for elongated bodies Test specimens that are moved longitudinally so that the twist is caused by the rotary movement of the Rotating body and the longitudinal movement of the test material is influenced. All of these rotating bodies are also suitable for imparting twist to the test material in terms of processing, which means that the test material mentioned here is then an intermediate product or in the rotating body of the preliminary product processed to the product.
Description
Der längsbewegte Prüfkörper 7', hier beispielsweise ein Gam, wird von aussen gegen die Mantelfläche 2 des Drehkörpers 1 geführt, so dass der Prüfkörper 7' durch den Drehkörper 1 ausgelenkt wird. Dann wird der Drehkörper 1 durch die Reibradpaare 26, 27 in Drehung versetzt, wobei der Prüfkörper 7' vorzugsweise zusätzlich seitlich geführt wird. Sobald die Nut 5, 6 neben dem Prüfkörper 7' auftritt, wird dieser durch die Drehbewegung und durch die eigene Längsbewegung in die Nut 5, 6 und damit in den Drehkörper 1 hineingezogen, so dass der Prüfkörper 7' nun die Stellung des Prüfkörpers 7 einnimmt Der Prüfkörper 7 durchläuft nun die Nut 5, 6 wobei er aus der Längsachse 8 an einer Stelle um etwa einen Abstand 20 ausgelenkt wird. Dies führt dazu, dass der Prüfkörper 7 sich in einem Bereiche 33 (Fig. 1) ausserhalb des Drehkörpers 1 verdreht Der Bereich 33 liegt vor dem Eintritt in den Drehkörper 1, was bedeutet, dass sich der Prüfkörper 7 in der Richtung eines Pfeiles 34 bewegt
