Definitions

  • the invention relates to a combing machine according to the preamble of claim 1.
  • combing machines the so-called
  • combing part or combing process means that e.g. ratio expressed as a percentage between the mass of the removed noils and the mass of the cotton wool supplied.
  • Combs are the short fibers removed from the fiber material by combing and some impurities. On the basis of the determined number of combeds, corrections can then be made, if necessary, to certain settings of the combing machine itself or of the machines which produce the wadding to be fed to the combing machine from fiber raw material.
  • the machine is switched off for determining the proportion of combedings and the combing machine belt, which is formed from the combined individual headbands according to a drafting system, is severed (torn off). Then a sieve flap is pivoted into the closed position in the guide means which serve for the pneumatic removal of the noils, or a comb collecting container is inserted. Then the combing machine is switched on for a short time, e.g. for about 10 seconds, started again. The combing machine belt is then torn off again, and the torn off combing machine belt and the combeds deposited on the screen flap or in the collecting container are weighed and compared. This process is carried out two to three times, and then an average is formed.
  • the object of the invention is to avoid the interruption in operation and the considerable work and time that are required in known combing machines for determining the proportion of combing material.
  • the object is achieved in a combing machine which is specified in the preamble of patent claim 1.
  • the above type is solved by a device for the ongoing or periodic automatic generation of a signal representing the number of combs while the combing machine is running.
  • a display can be controlled, on the basis of which the
  • Said device preferably contains a measuring device for determining the mass K of the noils removed per unit of time.
  • the device can then contain means for supplying a signal representing the mass Z of the individual headbands formed per unit of time or instead means for measuring the mass W of the wadding supplied per unit of time.
  • the mass W does not necessarily have to be measured: the device could also be given a constant (adjustable) value for the mass W, or the device could contain means for calculating the mass W from the known weight of the cotton wool supplied per unit length and per Unit of time fed length of wadding. This length depends on the number of comb games per unit of time and the amount of cotton wool feed per comb game. One could thus supply the device mentioned for the calculation of the mass W, for example, signals which represent the number of Comb combs per unit of time and represent the food amount set in the combing machine.
  • the said device measures the mass W of the cotton wool supplied per unit of time or receives or calculates it in a predetermined manner and additionally contains means for supplying a signal representing the mass Z of the individual headbands formed per unit of time, then the mass K of the combs removed per unit of time does not have to be measured , since the combing fraction A can also be calculated from W and Z as stated above: A m (WZ) / W.
  • FIG. 1 shows a schematic vertical section through a combing machine in the region of a combing head thereof
  • FIG. 2 shows a schematic front view (seen from the left in FIG. 1) of a part of the combing machine
  • Fig. 3 is a schematic rear view of the part of the combing machine shown in Fig. 2 and the
  • FIGS. 4 to 7 each show a different embodiment of the measuring device in a view corresponding to a section from FIG. 3, which determines the amount of combed removed per unit of time.
  • a combing head of a combing machine contains a vibrating tongs 1 in which an intermittently rotating feed cylinder 2 is mounted.
  • a cotton wool to be combed is fed to the feed cylinder 2 by a cotton wool winder 3, which is carried on two rotatable winding rollers 4 and 5.
  • a fiber beard is clamped between the clamping plates of the pliers by the cotton wool supplied and is combed out by a rotating circular comb 6 with which a rotating circular comb brush 7 also interacts.
  • the pliers 1 are then moved into their illustrated advanced end position and opened, and the fiber beard is removed from the cotton wool by a tear-off unit with pairs of rollers 8 and 9 torn off and combined with the previously formed fleece made of combed material.
  • the combed single-headed belt then runs through pairs of take-off rolls 10 and 11 and is delivered by them in the form of a belt or fleece to an outlet table 12 which is assigned to all of the machine's combing heads.
  • the short fibers, nits and impurities removed from the fiber material by the circular comb 6 and a fixed comb (not shown) are sucked as so-called combs through a guide shaft 13 into a suction channel 14, which is assigned to all the heads of the machine together .
  • the individual head belts from the various combing heads of the machine run on the outlet table 12, usually next to one another, to a common drafting system, of which three roller pairs 15, 16 and 17 are shown schematically in FIG. 2.
  • a trumpet 18 is arranged, which forms the nonwoven into a combing machine belt, which is then deposited in a can (not shown).
  • a combing machine of the type described above contains a device for the continuous or periodic generation of a signal representing the combing part.
  • Said device preferably contains a measuring device for determining the amount of combed removed per unit of time.
  • This measuring device can contain, for example, a movable sieve surface arranged in the flow of the noils pneumatically discharged through the suction channel 14. Noils are deposited on the sieve surface. The thickness of the deposited comb layer can then be measured before the layer is stripped again from the screen surface. The thickness of the comb layer forms a measure of the Channel 14 transported amount of combs.
  • a rotatable sieve drum 19 is arranged in the suction channel 14. A layer of combed is deposited on the front side of the sieve drum 1 facing the suction air flow.
  • a position transducer (not shown) is coupled to the bearings of the sensing roller 20 and emits a signal representing the thickness of the comb layer. This signal can be used directly as a measure of the amount K of the combs discharged through the suction channel 14 per unit of time.
  • the signal from the position transducer can, however, also be fed to a controller, for example, which adjusts the speed of the sieve drum 19 so that the thickness of the comb layer remains at a predetermined value. In this case, the control signal emitted by the controller can then be used as a measure of the amount of comb K.
  • the comb layer is removed from the surface of the screening drum 19 by a stripper element 22.
  • a sieve drum can also be arranged in such a way that noils can accumulate on its circumference for more than one revolution.
  • a vacuum is maintained inside the screen drum and the scraper element 22 is left or moved away from the screen drum.
  • the position transducer of the feeler roller resting on the combing layer then emits a signal as a measure of the amount of combing material K removed per unit of time, which signal indicates the rate at which the combing layer increases in thickness.
  • the position transducer can also be replaced by a limit switch which responds when the thickness of the comb layer reaches a predetermined value. In this case, the length of the time that elapses before the limit switch responds forms a measure of the amount of combers K removed per unit of time.
  • the sieve drum must also be emptied periodically, for example after the limit switch has been activated. For emptying the sieve drum, the negative pressure inside it can be released and / or stripper elements can be moved towards the circumference of the drum.
  • the thickness of the comb layer on the sieve drum 19 could also be determined optically instead of mechanically using the feeler roller 20 and the position transducer or limit switch coupled to it.
  • one or more light sources could be arranged inside the screen drum 19, which could be made of transparent material such as glass.
  • One or more light receivers would then be arranged outside, the output signals of which represent the weakening of the light from the light source or the light sources, which is dependent on the thickness of the comb layer.
  • the light source (s) and light receiver could both also be arranged outside the sieve drum 19 in such a way that the light receivers determine the reflection of the light from the light source (s), which is dependent on the thickness of the comb layer.
  • the screening drum 19 does not extend over the entire cross section of the suction channel 14, but only over part of the height of the suction channel, up to a flow divider plate 23 arranged therein.
  • a bypass channel is thus above the plate 23 24 is formed, which receives part of the air flow and the noils transported therein.
  • the bypass channel is generally necessary so that a sufficiently large negative pressure is available in the suction channel 14 in front of the screening drum 19 for the suctioning of the noils from the combing heads of the combing machine. Because of the U-channel, only a part of the noils can of course collect on the circumference of the sieve drum 19, for example about half. However, it is sufficient if the mass of this part of the noils is measured as described; the total mass of the noils can be read from the measured mass Calculate multiplication with a constant factor with sufficient accuracy.
  • Measuring device for determining the amount of comb removed per time unit through the suction channel 14 is shown schematically.
  • This measuring device contains one or more radiation sources 29, for example light sources, which are arranged on one side of the suction channel 14, and one or preferably several radiation receivers 30, for example light receivers, which are arranged on the side of the suction channel 14 opposite the radiation sources 29.
  • the radiation sources 29 and radiation receiver 30 form a light barrier.
  • the combs transported in the air flow through the suction channel 14 weaken the radiation impinging on the radiation receivers 30, and the radiation receivers emit a signal which is proportional to the mass K of the combs removed from the combing machine per unit time by the suction channel 14.
  • FIG. 6 schematically shows yet another embodiment of a measuring device for automatically determining the amount of combs discharged through the suction channel 14 per unit of time.
  • a chamber 31 which is separated from the suction channel by a flap 33 which can be pivoted about an axis 32.
  • An outlet channel 34 extends from the chamber 31 and opens into the suction channel 14 downstream of the flap 33.
  • a sieve plate 35 is arranged in the inlet of the outlet channel 34 and can be pivoted about an axis 36. However, the sieve plate 35 is normally in an open position (not shown).
  • Drive means 37 and 38 for the flap 33 and the sieve plate 35 are of one Control device 39 controlled by a timer.
  • the control device 39 controls the drive 37 periodically so that this pivots the flap '33 in their illustrated with a broken line position.
  • the suction channel 14 is then interrupted and its part coming from the combing heads is connected to the chamber 31.
  • the air flow with the combs from the combing heads therefore passes through the chamber 31 and - with the sieve plate 35 open - through the outlet line 34.
  • the air flow also takes combs which have remained in the chamber 31.
  • the control device 39 controls the drive 38 in such a way that it swivels the sieve plate 35 into the closed position shown, so that the combs brought up with the air flow are now held back on the sieve plate 35.

  • a drum separator which belongs to the combing machine, is arranged in the suction channel 14 itself.
  • the drum separator has a rotatable sieve drum 41, from the interior of which a suction opening or suction line 42 emanates Suction fan (not shown) is connected.
  • the combs brought up with the air flow through the suction channel 14 are deposited in the form of a layer or a fleece on the circumference of the sieve drum 41.
  • a rotatable fleece detaching roller 43 is in contact with this extent.
