Definitions
- the invention relates to a support disc Rotor spinning device according to the preamble of claim 1.
- the rotor spinning device is the spinning rotor with its rotor shaft stored in the gusset of two pairs of support discs and is by a tangential belt acting on the rotor shaft from above driven.
- One of the two facing the rotor Support disks on the one facing a light source Outside means that the incident light temporarily reflect or reflect the light temporarily interrupt.
- Part of the reflected light from the Light source hits a measuring device and is converted into signals converted for a speed measurement of the rotor.
- Kick to Example of a thread break at the spinning position this is over a thread monitor is detected and the rotor of this Spinning station stopped.
- the associated standstill of Support washers due to the lack of signals for the Speed measurement detected.
- Such rotor spinning devices are for example in the DE 41 21 387 A1 and DE 195 31 660 A1.
- From DE 43 13 753 A1 is a support disc for a Support disc storage of open-end spinning rotors known, at one end with signal transmitters for non-contact Speed measurement is provided by means of magnetic Field lines work. Are in the support disc Permanent magnetic pins fitted that carry an induction current produce. In another embodiment of the support disc The signal transmitter is made of aluminum or plastic ferromagnetic material formed.
- this known support disc there is the base of the steel support disc and the signal transmitter is a hole in the base body. On too an electrical signal can be taken off in this way.
- the generated induction current is in each case via an electrical Management of an evaluation device that is connected with various Control motors of the piecing device is connected.
- This inductive The method is intended to prevent the Support disc pairs imprecise signals are delivered.
- the Pickups must be relatively close to the surface of the Base body of the support plate to be positioned to sufficient accuracy and strength of the signals guarantee.
- the disadvantage is the required the surface-near position of the pickups disturbing air vortex.
- the present invention is therefore based on the object to develop a support disc so that the above Disadvantages of known support disks are reduced or avoided and the acquisition of signals for speed measurement is improved.
- the angular position of the inner surface of the openings of the support disc according to the invention offers the rotation of Support disc no hold for dirt deposits and works also self-cleaning. An overgrowth of the openings Dust and fiber deposits are effectively prevented and the detection of the light signals not through deposits with special needs.
- One preferably on both sides of the support disc beveled cutting edge allows an arrangement of the as an inclined Side surface of the cutting edge formed under an inner surface even steeper angles and thus reinforces the deposits preventive and also degrading effect.
- the cutting edge leaves preferred by milling or grinding produce that also in connection with the introduction of the Opening can take place in the support disc.
- the openings are advantageously slit-shaped and arranged radially. In this way one can desired for a precise speed measurement larger number of Make openings on a pitch circle in the support disc, without unduly weakening the structure of the support disc. The thus increased number of measuring pulses per revolution of the Support disc increases the accuracy of the speed measurement considerably.
- the support disc a the light beam, in particular a laser light beam, as diffuse scattered light reflecting surface, and the The light barrier is designed as a reflection light barrier.
- Laser light beam delivers even at low Beam cross-section as it is for small opening cross-sections is sufficient light intensity for that Light signal.
- the support disk preferably consists of Aluminum and is manufactured as an extrusion. After this Extrusion process has the base of the support plate on the Surface already has sufficient reflection behavior and does not require post-processing of the surface.
- Support disc are the openings using a little complex, cost-saving manufacturing process such as Example punching has been generated and the required angle ⁇ the inner surface is replaced by a advantageously formed from plastic component.
- the design of the support plate according to the invention can be easy and inexpensive to manufacture and prevents the build-up of Dirt deposits and any resulting Impairment of the speed measurement process effectively before.
- the base body 2 of the support disk 1 shown in FIG. 1 does not have a central bore 4 for receiving the here shown axis of the support disc 1 and carries on his Scope of the tread 3, which in a known manner to support the also serves rotor shaft, not shown here.
- the Tread 3 is for example one on the peripheral surface of the Support disc 1 mounted solid rubber tire from one wear-resistant rubber.
- the base body 2 also has eight rotationally symmetrical a pitch circle 18 arranged slot-shaped openings 5 to 12 on.
- the openings 5 to 12 run radially and are star-shaped at the same distance from each other on the pitch circle 18 arranged.
- the number of openings can be 5 to 12 and thus the number of signals per revolution can be increased.
- the inner surface of the to the outer edge of the support disc 1 Opening 5 forms a cutting edge 13, the tip 14 in the Sectional view of the support disc 1 in FIG. 2 in the direction of the axis of rotation 27 has.
- the part of the inner surface 19 of the Opening 5 which in the direction of the axis of rotation 27 of the Base body 2 is parallel to the axis of rotation 27.
- the side surfaces of the cutting edge 13, however, are on one Side perpendicular to and on the other side in one such angle ⁇ to a parallel to that Rotation axis 27 that during the operation of the Support disc 1 on the entire inner surface 19 of the opening 5 no deposits of dust or fiber residues can.
- the partial view of the base body 20 with the opening 15 in Fig. 3 shows an embodiment of the cutting edge 23, in which both Side surfaces 16 and 17 an acute angle ⁇ to the vertical form on the axis of rotation 27.
- the angles ⁇ and ⁇ result each 90 ° together.
- the Side surfaces 16 and 17 at an angle ⁇ of approximately 25 ° each steeper than the inclined side surface of the cutting edge 13 in Fig. 2 arranged. The deposit of dirt is still there counteracted more and the self-cleaning effect even more reinforced.
- the opening 25 of FIG. 4 can expediently by drilling or Milling of the base body 21 in one operation getting produced.
- a rotationally symmetrical shape of the Create opening 25 with the inner surface of opening 25 also occupies such an angular position that the Dirt deposits are prevented.
- FIG. 5 The state of the art is illustrated in section in FIG. 5 shown partial view of a base body 22 with the Opening 26.
- the formation of the opening 23 as through Stamping can be made, favors the construction of a Dirt deposit 24, which ensures reliable signal detection is hindered.
- With the support disc 1 according to the invention such a deposit of dirt and fiber parts and the resulting impairment of Preventing the speed measurement process.
