Definitions

  • the invention relates to a device for measuring the sliver thickness and the non-uniformity of fiber slivers, preferably on spinning preparation machines, with a compression member compacting the fiber sliver and with a measuring member arranged thereon, mechanically scanning the compressed sliver in a measuring channel and formed by a leaf spring provided with a strain gauge for the thickness and the unevenness of the sliver.
  • the measuring channel is provided in a wall which integrally connects to the outlet opening of the compression member formed by a band funnel, and the leaf spring is fastened to the band funnel and extends along a generatrix of the band funnel.
  • This known device is now to be improved by the invention in such a way that even very short non-uniformities can be measured at high belt speed and that a simple range adaptation to changing belt numbers can be carried out.
  • the measuring channel is provided in a measuring part which is arranged interchangeably on the compression member and is equipped with a compressed air connection, and in that the leaf spring is arranged transversely to the running direction of the fiber sliver.
  • the arrangement of the measuring channel in a measuring part that can be replaced on the compression element has the advantage that it is no longer necessary to replace the entire compression element, but only the named component or even only a part of it, in order to adapt to changing band numbers.
  • the compressed air connection offers the possibility of blowing out dust and / or cooling the measuring point. Due to the arrangement of the leaf spring according to the invention, it can be designed such that it has a very high natural frequency. This makes it possible to measure even very short irregularities at higher belt speeds than before.
  • band funnel T serving for the compression of a sliver with a funnel wall 1 and an inlet and an outlet opening 2 and 3 respectively.
  • band funnels are known and are used in particular on draw frames or cards; on lines, for example, in the direction of flow after the drafting system and / or in front of a pair of calender rollers.
  • the band funnel can be assigned to the can stock, for example, or it can be provided to combine the card fleece.
  • the band funnel T has a gradation into which a measuring part MT having a measuring channel 4 is inserted.
  • This consists of two parts, namely a channel part 5 and a stop part 6, between which a leaf spring BF is clamped.
  • the leaf spring BF serves as a measuring element for the thickness of a sliver running through the band funnel 1 and the measuring channel 4.
  • FIGS. 5 and 6 each show a view of the clamping surface of the channel part 5 or the stop part 6 facing the leaf spring BF.
  • the structure of the measuring part MT is now explained with reference to FIGS. 1 to 6, wherein the scale is 4: 1 in each case.
  • the channel part 5 is approximately plate-shaped and has on its clamping surface the measuring channel 4 provided with a conical inlet part, which is formed by a groove in the channel part 5.
  • the channel part 5 is provided with a centering rib 7 which runs transversely to the measuring channel 4 and which is latched into a corresponding groove in the graduation of the band funnel T.
  • the fixation in the third coordinate direction is carried out by means of two screws 8, which are pushed through corresponding bores 9 of the stop part 6 and slots 10 and 11 in the leaf spring BF or in the channel part 5 and in Threaded bores 12 of the band funnel T are screwed in.
  • the measuring part MT Since the screws 8 at the same time for attachment serve of the measuring part MT on the belt funnel T, the measuring part can be replaced by simply loosening and tightening the screws 8 and thus the device consisting of the belt funnel T and the measuring part MT can be easily adapted to changing belt numbers.
  • the leaf spring BF as shown (see in particular FIG. 4) consists of a measuring beam 13 and two torsion bars 14, by means of which the measuring beam 13 is fastened to a connecting part 15.
  • the leaf spring BF consisting of the parts mentioned is made in one piece and is clamped at the two points 16 marked by hatching in FIG. 4 in the transition region between the connecting part 15 and torsion bars 14 between the channel part 5 and the stop part 6.
  • the measuring bar 13 of the leaf spring BF lies across the measuring channel 4 and is prevented at its ends by two bearing surfaces 17 of the stop part 6 from pivoting away from the measuring channel 4.
  • a sliver coming from the sliver funnel 1 and running through the measuring channel 4 is compressed by the measuring bar 13 in the measuring channel 4 and generates a pressure on the measuring bar 13, the absolute value of which increases reproducibly with increasing sliver thickness.
  • Each change in the strip thickness causes a corresponding change in this pressure and the force acting on the measuring bar 13.
  • the measuring bar 13 cannot pivot away from the measuring channel 4, but instead undergoes deflection, and in the measuring bar 13 there is a positive elongation on one surface and a negative elongation on its other surface, which is proportional to the force acting and thus a measure of the strip thickness is.
  • the mechanical quantity strain is converted into an electrical quantity by means of strain gauges arranged on the measuring bar 13 (see FIG. 6a).
  • the support surfaces 17 are less than 1 mm in front of the web of the stop part 6 connecting them.
  • the maximum possible deflection of the measuring beam 13 is thus limited to this distance and the web between the two stop surfaces 17 acts as Stop against overstretching or overstressing.
  • a tube or nipple 18 is attached to the stop part 6 on both side walls transversely to the measuring channel 4 of the channel part 5.
  • the tubes are each fastened in a bore 19 penetrating the corresponding side wall.
  • One of the tubes 18 is used for supplying the electrical connections, the other enables simple cleaning and cooling of the measuring part MT by means of compressed air. The cleaning is carried out by intermittent and the cooling by constant supply of compressed air.
  • the two torsion bars 14, which position the measuring bar 13 and determine its pivot point, additionally fulfill the further important task of preventing the cracking effect when the measuring bar 13 is locally heated by the continuous fiber sliver and thus prevent the occurrence of mechanical stresses as a result of temperature fluctuations. So that the measuring bar 13 is not worn out by the sliver, it is provided on its side contacting the sliver with a pressure plate 20 made of hard metal or ceramic, which is applied to the measuring bar 13. In addition to the strain gauges, a temperature sensor can also be provided on the measuring bar 13 or in its area to take account of any temperature fluctuations.
  • FIG. 6a shows the basic arrangement of the strain gauges on the measuring bar 13 and the evaluation of their signals.
  • the figure schematically shows the measuring bar 13 supported against the abutment surfaces 17, on the pressure plate 20 of which a force F would act through a sliver.
  • two strain gauges D1 and D3 or D2 and D4 are arranged on each of these.
  • strain gauges lie symmetrically to the imaginary point of application of the force F in the middle of the measuring channel 4 (FIG. 5). This ensures that interfering effects caused by friction of the fiber sliver are fully compensated for by the ambient temperature or by local heating of the measuring beam 13.
  • Each strain gauge D1 to D4 has a certain electrical resistance R1 to R4, which resistances are all the same. Since the relative change in resistance when the measuring beam 13 bends is known to be proportional to the elongation of the strain gauges, the determination of the elongation can be carried out by measuring this change in resistance. This is done with the aid of a Wheatstone bridge circuit, which consists of four branches, which are formed by the ring-shaped interconnected resistors R1 to R4.
  • FIGS. 7 to 13 show a second exemplary embodiment of a band funnel T '(FIGS. 7, 8), one suitable for use with this stop part 6' (FIGS. 9, 10) and a suitable leaf spring BF '(FIGS. 11-13 ).
  • the scale in FIGS. 7 and 8 is 2: 1 and in FIGS. 9-13 5: 1.
  • the band funnel T ' is basically the same as the band funnel T shown in FIGS. 1 to 3 and has an outlet opening 3' of approximately oval or elongated cross-section as the main difference compared to this. This shape leads to a corresponding deformation of the cross section of the fiber sliver, so that the leaf spring no longer lies tangentially thereon but along a side surface.
  • the band funnel T ' also has a step following the outlet opening 3', in which a measuring part is inserted and fixed by screws (not shown). While in the measuring part MT of the first exemplary embodiment (FIGS. 1-6), with reference to FIG. 1, the channel part 5 is at the bottom and the stop part 6 is at the top, this is the reverse in the second exemplary embodiment of FIGS. 7 to 13.
  • the stop part 6 ' (FIGS. 9, 10) thus lies directly on the graduation of the band funnel T' and the channel part is arranged above this.
  • the leaf spring BF '(Fig. 11-13) is clamped between these two parts. Which of the two parts, channel part or stop part, lies directly on the gradation of the band funnel T or T 'is not essential to the invention.
  • the channel part of the second embodiment practically corresponds to the channel part 5 (FIG. 1) of the first embodiment and is therefore not shown.
  • the stop part and the leaf spring between the two exemplary embodiments, which are now to be explained with reference to FIGS. 9-13. Since the leaf springs in particular are different, the leaf spring will be described first.
  • the leaf spring BF ' essentially consists of a thicker support part 21 forming the edge part thereof and a measuring bar 13', which has one end face directly and a torsion bar 14 'at its other end the carrier part 21 is connected. Since the leaf spring BF 'is also made from one piece, "connected" in this context naturally does not refer to a connection between two different parts but the boundary of two regions of one and the same part.
  • the leaf spring BF ' has two holes 22 for the screws 8 (FIG. 1) corresponding fastening screws for rough adjustment in the measuring part. The fine adjustment is carried out by screws (not shown) which are guided in a second pair of bores 23 and screwed into corresponding threads 24 of the stop part 6 '(FIG. 9).
  • the measuring bar 13 ' has a thickening 25 with the pressure plate 20 on its area contacting the fiber sliver which is passing through and is to be measured.
  • the four strain gauges are arranged on the surface of the measuring bar 13 ′ facing away from the pressure plate 20, preferably in the area between the thickening 25 and the end of the measuring bar 13 merging into the carrier part 21.
  • the stop part 6 ' (FIGS. 9, 10) is correspondingly adapted to the leaf spring BF' and has at its edge an approximately U-shaped bearing surface 26 for the leaf spring BF 'and in the area of the measuring bar 13' a gradation set back against the bearing surface 26 27 on.
  • the gradation 27 is divided in two by a web 28 arranged in the area of the pressure plate 20 (FIG. 11). The web 28 projects beyond the step 27, but is lower than the support surface 26 and forms a stop limiting the deflection of the measuring beam 13 '.
  • the stop part 6 ' also has two chamber-like cutouts 29 and 30.
  • a bore 19 penetrates the corresponding side wall of the stop part 6 'and at least one tube 18 is fastened in one of the bores 19.
  • the electrical connections of the strain gauges are guided through this tube 18 via chamber 30 and gradation 27 to the outside.
  • a nipple is fastened (not shown), through which compressed air is blown from the outside into the stop part 6 'for cleaning and cooling the measuring point, which passes through chamber 29 and web 28 via the measuring beam 13' .
  • the leaf spring BF ' has larger dimensions than the corresponding surface of the stop part 6'. This stems from the fact that the leaf spring BF 'matching the illustrated stop part 6' only extends up to the line G shown in broken lines at its upper and left edge in FIG. 11.
  • the leaf spring BF 'in this case has an approximately L-shaped support part 21 and the bore 23 on the left in FIG. 11 is located between the torsion bar 14' and the adjacent bore 22.
  • the variant of the leaf spring BF 'shown in FIGS. 11-13 when used the stop part 6' and of course the channel part 5 (FIG. 1) to be modified accordingly would be distinguished by the fact that the measuring bar 13 'and the torsion bar 14' are surrounded on all sides by the carrier part 21 and are thus optimally protected against external influences. If the leaf spring BF 'has the smaller dimensions indicated by the border G, then both the measuring bar 13' and the torsion bar 14 'lie on the outer edge of the measuring part MT (FIG. 1) and can thereby be damaged by external action. In the leaf spring BF 'shown in FIGS. 11 to 13, this is precluded by the part 21' of the carrier part 21 lying outside the border G, which forms a shield for the measuring bar 13 'and the torsion bar 14'.
