Definitions

  • the invention relates to a device for generating or Further processing of sliver, e.g. a stretch or a card, wherein the sliver is guided between two feeler rollers, the feeler rollers for measuring the sliver thickness are radially variable in the distance and at least one of the sensing rollers is driven by a shaft.
  • sliver e.g. a stretch or a card
  • a generic device such as the regulating section RSB 951 from Rieter Ingolstadt Spinnereimaschinenbau AG, points to Measurement of the sliver pairs of feeler rollers, which in their Distance are changeable. That between the pairs of feeler rollers sliver passed through does more depending on its thickness or less distant removal of one sensing roller from the other Sensing roller. The rollers pressed together by spring force follow the different sliver thickness of the between them Sliver. The sliver thickness determined in this way is sent to the control of the Machine passed on or at least displayed. Through the Determination of the sliver thickness can the manufacturing process of Sliver can be improved in that a sliver with extremely uniform thickness is produced by the machine in its Setting, e.g.
  • sensing roller pairs are located at the drafting system entrance and / or at the drafting system exit of the route.
  • At the drafting system entrance measured the thickness of the sliver entering the drafting system.
  • individual drafting roller pairs accelerated more or less, so that a too thick sliver in his Thickness reduced and a too thin sliver stretched less thus increased in thickness.
  • A can appear at the drafting system exit there are another pair of sensing rollers, also called a pair of calender rollers, which determines the result of the drawn sliver. It will be here quality monitoring of the drawn sliver is carried out.
  • one sensing roller is often arranged stationary.
  • the second sensing roller is arranged to be radially movable in order to different sliver thickness can be deflected.
  • the Movable probe disc is also driven to slip the Sliver between the feeler rollers and thus in the worst case Avoid misalignment of the sliver.
  • the object of the present invention is therefore to provide a pair of sensing rollers create, even with rapid changes in the thickness of the sliver reacts very accurately and exact measurements of the thickness of the sliver supplies.
  • the object is achieved by the features of claim 1. If the wave, over which the sensing roller is mounted, in a drive shaft and Tracer roller shaft divided, and are the two shaft parts by means of one a coupling that allows an axial offset is connected Deflection of the feeler roller with a reduced mass. Is deflected only the feeler roller with its feeler roller shaft and its bearing. The Deflection of the mass of the drive, the drive shaft and their bearing not necessary. This is a significant reduction in moving Mass takes place when measuring the sliver. Changes in In this way, sliver thicknesses are up without great time lag Traversable due to high inertia forces. The measurement of the Sliver is therefore very precise. The present invention realized thus a significant reduction in mass of the moving parts.
  • the shafts are arranged on individual swiveling pedestals, so is a technically simple solution to deflect the feeler roller.
  • Swiveling the pedestals is one roller from the other Radial roller removed radially. The removal happens during the measurement of the sliver.
  • the size of the distance corresponds to different sliver thicknesses.
  • the two are advantageous Bearing blocks connected in such a way that after reaching a predetermined pivoting of the roller bearing block Drive bracket also pivoted. This ensures that for example when the sliver is wound, i.e. at a faulty operation of the device according to the invention, first the Roller bearing block is deflected up to the stop and then the Drive bracket pivoted. Damage to the Tracer roller device is avoided that the tracer roller the pressure of the sliver can yield.
  • a Eccentric lifting device which acts on the drive bracket, triggered. This opens the pair of sensing rollers permanently, so it remains in its open position. It is by means of the eccentric lifting device also possible for cleaning processes or for manual or automatic introduction of sliver between the two feeler rollers, open the feeler rollers and after inserting the sliver the eccentric lifting device to close the two feeler rollers again.
  • a maximum distance between the sensing rollers of 30 mm is possible. 30 mm is generally sufficient for a To be able to take up sliver rolls on a feeler roller. Is the Drive bracket pivoted to the maximum, so it is particularly advantageous when the drive bracket acts on an off switch of the device. It it is thus ensured that there is no even larger sliver winding builds up and leads to destruction of the device.
  • the Home position means that the feeler rollers lie against each other or one Distance in the absence of sliver of less than 0.5 mm, preferably about 0.05 mm.
  • To deflect the roller pedestal to enable the deflection of the drive pedestal points to the Spring bearing block acting a softer characteristic than that on the Actuator bracket acting spring. So first the softer feather deflected to its maximum deflection and only then does the harder one Spring actuated.
  • a torsionally rigid, flexible shaft coupling has proven to be particularly advantageous between the drive shaft and the feeler roller shaft. So that will a shaft offset of the two waves allows, although a Torque can be applied to the sensing roller. Has been particularly advantageous proved the use of a multi-plate clutch. For one accurate measurement of the sliver, it is advantageous if only small Forces to generate a misalignment of the clutch are required.
  • a further reduction in the mass of the sensing roller is achieved by the Tracer roller is axially hollow turned. This makes the feeler roller extremely light educated.
  • weight-reducing axial holes in the feeler roller can be arranged to also the mass of inertia Reduce the feeler roller and thus a quick and exact measurement of the To enable sliver.
  • the bearing can be axially fixed Tracer roller and thus additionally on weight due to the required Components are dispensed with.

  • Drive shaft 15 is rotatably mounted in a drive bracket 2.
  • the roller shaft 16 is rotatably supported in a feeler roller bearing block 3.
  • the storage is preferably carried out by means of needle bearings, which are not are shown. Needle roller bearings have the advantage that they are very small. However, if space permits, in Drive bracket also other types of bearings possible.
  • the Drive shaft 15 has a toothed belt pulley 14 at one end connected.
  • the toothed belt pulley 14 does not act by means of a illustrated drive driven toothed belt, which the Drive shaft 15, the clutch 1 and the roller shaft 16 with one on it attached feeler roller 6 drives.
  • the toothed belt drive is also a drive by means of a flat belt, a chain or other similar Drive means possible.
  • the drive can also be used directly of a motor, which is flanged to the drive shaft 15.
  • the drive bearing block 2 is connected in a rotationally fixed manner to a pivot axis 13.
  • the pivot axis 13 is by means of collar bushings 21 and 21 'and one Disk 23 rotatably supported in the bearings 20 and 20 '.
  • the plain bearing the pivot axis 13 by means of collar bushings 21 and 21 'and the disc 23 has proven itself, since the later still with a small space described small pivoting paths of the drive bracket 2 so can be realized well.
  • a carrier 24 is arranged, on which by means of an axis 19 as an eccentric lifting device, a toggle lever 18 on the Drive bracket 2 is attached.
  • the toggle lever 18 includes from one Spring 5.
  • the spring 5 becomes more or less strong pressed together. This is a pivoting of the drive bracket 2 allows to a certain extent. Once that particular measure is exceeded, the knee lever 18 bends out and prevents Spring back the drive bracket 2 to the starting position. This is advantageous if e.g. by means of winding around the sensing roller 6 complete unit is pivoted.

  • the sensing roller 6 with a recess 28 and with holes 26 Mistake. This ensures that everyone on the roller bearing block 3 stored parts are particularly light and therefore fast Response of the sensing roller 6 mounted in the sensing roller block 3 Changes in the sliver thickness is made possible.
  • the coupling 1 is designed such that it can be easily deflected, i.e. allows an axis offset and on the other hand the torque that over the Drive means is brought to the drive shaft 15, transfers well.
  • the Coupling 1 must therefore be rotationally stable and have a lateral offset Drive shaft 15 in the event of a deflection of the feeler roller bearing block 3 Allow roller shaft 16. Due to a low restoring force of the clutch 1 is caused that the mass reduction of the deflectable bearing block 3rd not again due to an excessively high provision in one axially aligned position of the drive shaft 15 and the roller shaft 16 Niece does.
  • Coupling 1 a torsionally rigid, flexible shaft coupling, can be equipped with two disk packs, one radial Compensates for shaft misalignment when connecting two shaft ends.
  • the clutch consists of two disk packs, two hubs and one Spacer. Between the toothed belt pulley 14 and the drive shaft 15 a slip clutch 25 is provided. This ensures that in If the sensing roller 6 is blocked, e.g. due to wrapping of the sliver around the feeler roller 6, the clutch 1 is damaged if the drive acting on the toothed belt pulley 14 does not stop yet.
  • the Coupling is preferably in the area of the drive bracket 2 and on the drive shaft 15 is arranged to act. Otherwise, if they are on the Tracer roller shaft 16 would act, an additional increase in the the scanning roller bearing block 3 movable weight.
  • One of the main ideas in the inventive arrangement is that the drive of the sensing roller and the sensing roller itself at least partially are decoupled from each other. This is a deflection of the feeler roller 6 possible without the parts required to drive the sensing roller 6 are necessary to deflect with. This reduction in mass is one enables very precise measurement of the sliver for the first time.
