Ring rail arrangement in Spinnland twisting machines

The invention relates to a ring rail arrangement for spinning and twisting machines ,, for x-ielcher the ring rail with on '' and _a abbewegten on vertical rods guided guide blocks is connected.

The present invention has for its object, the ring rail ie in their longitudinal direction to fix _Ä "any longitudinal displacement of the ring rail au prevent" These longitudinal fixation der.Ringbank is especially important for high-speed Hochlelstungsswirnmaschinen of considerable importance "

this longitudinal displacement of the ring rail with double-sided spinning or Twisting machines with common drive for both rare to prevent., one has ^ e two opposite guide blocks 'connected with each other' with consideration for the intermediate Drive elements, these connecting links must be bow-shaped, but ^ also with regard to

can ,, that with it any flexibility of the support frames in Reference to the Pilhrungs rods,? i.e. every pivoting movement of the Guide blocks can be prevented,

For double-sided spinning and twisting machines with separate drives both Ssi'cen it has secured the ring rail with the guide bucking by pins "This compound is also * * insufficient ₅ to effect a LängererSchiebung of the ring rail or" every pivotal movement of the guide brackets to particular at scjinell running machines prevent »In addition, this pin connection of the ring rail has the disadvantage that a cumbersome dismantling and Neuraon'cagt is necessary to remove and clean the ring rail ο

In the ring rail assembly for spinning and twisting machines, the stated object is achieved according to the invention is that two adjacent Piihrungsböeke are connected by a bending stiffness in a horizontal plane arranged _t parallel to the ring rail leveler ,, the firmly clamped at least at one end in a guide block is "With this new training, not only is the exactly right-angled position of the guide blocks to the ring rail achieved, but also every doho and the smallest pivoting movement of the guide blocks and thus also any longitudinal displacement of the ring rail is prevented"

The details of the invention and its further advantages are shown below with reference to one in the drawing Embodiment explained in more detail. The drawing shows graphically the ring rail arrangement on one side of the machine »

With I ₅ la round vertically arranged guide rods of a spinning or twisting machine are referred to. which Führungiäböcke _B 2 are mounted 2a "These guide blocks have lugs 5 on _s in which chains or bands 4 ^ attack, with which in a known manner, the guide blocks 2, 2a are on the guide rods 1, la moved up and down.

The guide jaw is designed to support a ring rail, which is indicated in the drawing with dash-dotted lines at 5 * The rear vertical edge β of this ring rail is inserted into a corresponding longitudinal groove 7 of each guide bracket 2, the ring rail also being on one Support surface '8 of the guide blocks 2 _D 2a rests. Corresponding recesses 9 in the vertical edge β center it between the two guide blocks, so that the ring rail is thus also secured against longitudinal displacement in the direction L with respect to the guide blocks,

To each pivoting movement of the guide blocks 2 _Ä 2a around the guide la '

rods 1 to prevent are, according to the invention, two adjacent Guide blocks by a fixing rod Io which is rigid in the horizontal plane and is arranged parallel to the ring rail 5 connected to one another ^ xvobei this fixing rod at least with one end is firmly clamped in a guide block "

To with regard to an uneven floor or a lowering of the floor ^ on which the spinning or twisting machine is set up virdj, to be taken into account and any constraint or jamming of the Guide blocks on the guide rods through the connection to avoid the fixing rods Io ^ is shown in the

In an advantageous embodiment, the fixing rod Io is only firmly clamped at one end loö in the one guide block 2 _, while the other end loa of the fixing rod is mounted in a longitudinally displaceable manner in the adjacent guide block 2a, but is secured against transverse displacement in the direction. The sine ends of the fixing rod Io in the full width B of the FührungsboeL-cs 2 is furthermore advantageous clamped "This clamping can be effected by, for example," ,, that the guide bracket 2, a horizontal clamping screw is provided _Ä acting on a narrow side of the fixation rod Io and if the other narrow side of this rod is fixed, the guide block presses. In the particularly advantageous embodiment shown, a different type of clamping is provided, in which in each guide block a V-ledge 11 is provided, the length of which appropriately corresponds to the width B of the guide block, and which is pressed against a narrow side of the fixing rod Io when it is tightened and thus clamps the latter tight In the embodiment shown, there is a transversely displaceable wedge iste 11 and a vertical screw 12 are provided for tightening this wedge bar ^ this screw going through a corresponding opening in the bar 11 and is screwed into the guide block 2 _{3 2a.} It can be seen from the drawing that the groove in the guide block and the corner bar have a height h, which is roughly twice the position of the fixing rod, _a where in the lower area c .-. ■■ _ ■ · JK'ut

the end of the rod clamped by the outer wedge strip © 11 is arranged in position _a while in the upper groove area with little play _Ä as indicated at a. but secured against transverse movement in direction Q «Here the rod end can loa. in the direction of Q only about the game a _s so only; move by a fraction of a millimeter "The resulting possible pivoting movement X in the horizontal plane around the guide rod 1 is extremely small, so that with regard to the large, usually over 1 mtr. the distance A of the guide blocks 2-, 2a, the pivoting movement Y of the guide block 2 around the guide rod 1 is practically Hulli, as does the longitudinal displacement L of the ring rail »

Due to the vorbesehriefoeiie original design, not only is the right angle R between guide brackets 2 _S 2a and fixing rod Io or ring rail 5 secured, but also a relatively rigid position of the ring rail relative to the guide rods l _a la created Direction L excludes.
