    Description: The invention relates to a winding machine and a method for winding cotton wool.
    [0002] Cotton rolls are usually produced by means of winding machines in which the cotton is wound on an empty sleeve between at least two winding calenders. From an upstream creel, 24 to 32 slivers of cans are fed to a drafting system and a set of pressure rollers, stretched and doubled, and then wound up on a tube.
    According to the known prior art, fluctuations in the wadding mass are corrected manually by the operator of the wadding machine during winding. For this purpose, the length of the rolled-up wad is divided into 10 equal parts, weighed individually and, based on the deviations determined, the main draft of the drafting systems is adjusted at 10 intervals over the winding process.
    It is therefore disadvantageous, of course, to first produce a cotton wrap, to destroy it in a time-consuming manner and to obtain a conclusion about the warpage or the uniformity of the winding via the weight.
    The object of the invention is to provide an inexpensive and reliably working winding machine and a method for producing a cotton wool from fiber tapes, with which a high quality cotton roll is produced.
    The invention solves the problem set by the teaching of claim 1 and 12; further advantageous design features of the invention are characterized by the dependent claims.
    According to the technical teaching of claim 1, several fiber slivers are guided in the winding machine to a winding unit, on or in which a roll of cotton is formed.
    According to the invention it is provided that the winding machine has a measuring system with which the thickness of the wadding to be wound can be determined, and at least one actuator for adjusting the thickness of the wadding to be wound up.
    Thus, the uniformity of the cotton wool generated can be checked and adjusted if necessary during operation. It is no longer necessary to determine the thickness or uniformity via the weight of sections of a cotton wrap. By recording the cotton thickness in operation, it is possible to achieve a uniform cotton weight over the wound length with little effort.
    It has been found to be very advantageous that the thickness of the wadding to be wound is measured at a measuring gap which is arranged on two rollers. In particular, from the distance between two rollers, for example the winding roller and a pressure roller, the measuring gap is formed through which the fiber sliver or the wadding runs. When the mass flow of fibers changes, a roller lifts off, for example the pressure roller from the winding roller, and the measuring gap increases. This change can be measured and used to adjust the mass flow.
    In an advantageous embodiment, the winding unit is formed by two winding rollers. One of the winding rollers can be the reference point for measuring the wad thickness. At the same time, at least one winding roller can be used to influence the weight of the wadding or sliver formed, for example by changing the tension between a winding roller and a previously arranged roller. As an alternative or in addition, the main draft in the drafting systems arranged in the inlet area can also be changed. Another additional or alternative way of influencing the wadding quality can be done by changing the tension between the pressure rollers and / or by changing the tension between the winding rollers.
    According to the quality of the fibers to be processed and the number of slivers, the load between the winding roller and the pressure roller can be adjustable. This means that manual, semi-automatic or fully automatic adjustment of the winding machine can be carried out for each wadding quality for a given load and if there is a deviation from a controlled variable.
    It has been found to be particularly advantageous to arrange the pressure rollers together on one frame. The load on the pressure rollers relative to one another can be adjusted via this frame, so that the quality of the wadding can also be adjusted here. The distance between the printing rollers and the winding rollers can be adjusted via a common drive on the frame for all the printing rollers, since only the frame has to be adjusted.
    In a preferred embodiment, the frame is arranged pivotably about a pivot point on the machine frame of the winding machine. The pivotability enables easy positioning of the measuring systems in the area of the measuring gap. Because the pressure rollers with the frame act on the cotton with a predetermined load, which runs through the measuring gap between the winding roller and the pressure roller, any difference in mass will affect the gap size and is therefore measurable. The frame with the pressure rollers swings with very small deflections around the pivot point as soon as the thickness of the cotton deviates from a preset thickness. These deflections can be recorded and determined via the measuring system, which is designed as a length measuring system, as an angle measuring system or as a voltage measuring system. The roller can be loaded by its own weight and / or by an additional pneumatic or hydraulic load.
    CH 708 290 B1 The measuring system determines the thickness of the wadding to be wound up as a controlled variable, which is compared in a controller or a control with a reference variable and, in the event of a deviation from the reference variable, generates a signal by means of which at least one actuator for changing the operating parameters the winding machine can be operated. It can be operated manually, semi-automatically or fully automatically.
    It is crucial in comparison to the prior art that the deviation can be recognized and corrected during operation without destroying a finished winding and iteratively adjusting the winding machine.
    Preferably, in the event of a deviation in the measured thickness of the wadding via a motor as an actuator, the draft can be set in a drafting system, as a result of which the sliver or the subsequent wadding becomes thinner or thicker.
    Alternatively, the actuator can be designed as a motor with which the tension between the pressure rollers and at least one winding roller is adjustable. It is used to measure and control the measuring gap practically at the same time. The controlled system is kept very small.
    The inventive method is characterized in that the thickness of the wadding to be wound can be determined by means of a measuring system integrated in the winding machine, the thickness of the wadding being adjustable via at least one actuator. On the one hand, the method enables the cotton quality to be determined during operation. On the other hand, the method enables the wadding quality produced to be adjusted during operation, so that a constant wadding thickness is achieved over the entire length of the wadding lap.
    In an advantageous embodiment, the draft of the sliver is set in an upstream drafting system via an actuator.
    Alternatively, the tension between the winding unit and at least one pressure roller can be adjusted via an actuator.
    Furthermore, the thickness of the wadding can be regulated via the distance between the pressure rollers, which are arranged in a common frame.
    The invention is explained in more detail below with reference to two possible schematically illustrated exemplary embodiments. It shows:
    Fig. 1: a first embodiment of a winding machine in a schematic representation;
    Fig. 2: a second embodiment of a winding machine in a schematic representation.
    In Fig. 1, a winding machine 1 is shown, as it is used for example in the combing preparation in the textile industry. Several slivers are fed to the winding machine 1 via cans and are uniformized and doubled in a drafting device, not shown, and possibly in a table calender, in a table calender, not shown, in front of the inlet area 2, in which the individual slivers are brought together, the cotton 3 is formed. Twice 12 to 16 slivers can be fed from cans to the winding machine 1, uniformized and doubled and stretched in a drafting system and fed via an inlet area 2 in the material flow direction 7 to several pressure rollers 4a-4c. The cotton 3 formed from the fiber tapes is then passed into the feed area between two winding rollers 5a, 5b and a winding tube 6 for producing a cotton roll.
    As an alternative to this embodiment with the two winding rollers 5a, 5b, winding machines are known in which the winding is formed by more than two winding rollers or within a circulating belt or by a belt with a winding roller. However, the method for producing the cotton roll is not relevant to the invention.
    In or on the inlet area 2, a pre-compressor 8 can be arranged, which further homogenizes the cotton 3 and thus, for example, reduces the hairiness of the cotton roll. In this exemplary embodiment, the printing rollers 4a-4c are arranged and supported in a triangular shape on their own frame 16, the cotton 3 being carried out between the printing roller 4c and the winding roller 5a. The measured gap between two rollers, in this exemplary embodiment the pressure roller 4c and the winding roller 5a, is referred to below as the measuring gap 15. The frame 16 of the printing rollers 4a-4c is rotatably mounted on the machine frame about a pivot point 14 and can have a separate common drive for the printing rollers 4a-4c. Furthermore, the gap between the pressure rollers 4a and 4b and between the pressure rollers 4b and 4c can be adjusted jointly or separately on the frame 16.
    In the embodiment of FIG. 2, about 12 to 16 slivers each run from cans, not shown, into a drafting system 10, 12, are stretched there and doubled in a table calender 11, 13. The fiber tapes, which are guided through the drafting system 10 and the table calender 11, are brought together with the fiber tapes from the drafting device 12 in the table calender 13, so that the wadding 3 can consist of a total of 24 to 32 fiber tapes before it is wound up. In the inlet area 2, the cotton 3 runs up a ramp in the material flow direction 7, in which it is adjusted and guided in width and then transported further between the pressure rollers 4a and 4b. The cotton wool 3 rotates around the pressure roller 4b by approximately 180 ° until it is fed between the pressure roller 4c and the winding roller 5a of the sleeve 6 and wound up. The wadding 9 then formed can have an outer diameter of up to 700 mm. The
    CH 708 290 B1
    Ejection position of the cotton roll from the winding machine is marked with the cotton roll 9a. The gap between two rollers, in this exemplary embodiment between the pressure roller 4c and the winding roller 5a, is referred to below as the measuring gap 15. In this embodiment, the pressure rollers 4a-4c are arranged in a row and mounted on their own frame 16 which is mounted on the machine frame so as to be pivotable about the pivot point 14. The frame 16 of the printing rollers 4a-4c can have a separate drive for the printing rollers 4a-4c. Furthermore, the gap between the pressure rollers 4a and 4b and between the pressure rollers 4b and 4c can be adjusted jointly or separately on the frame 16.
    About the measuring gap 15, that is, the distance between the pressure roller 4c and the winding roller 5a, the thickness of the cotton 3 can be detected and measured, which is equivalent to the number of fibers in the cross section of the cotton 3. By detecting the thickness, which can be set to 0.3 mm during operation, for example, it is possible to regulate the main draft in the drafting systems 10 and 12. This means that a uniform wad weight can be achieved over the wound length with little effort, without having to destroy the wrap.
    Furthermore, by determining the thickness of the cotton 3 in the measuring gap 15, a warp or a tension between the pressure rollers 4a-4c and the winding roller 5a can be set, so that at the same time a regulation with different thicknesses takes place.
    The measuring system for detecting the measuring gap 15 uses in this embodiment, the storage of the printing rollers 4a-4c on a frame 16 which is pivotally arranged about the pivot point 14 on the machine frame. The measuring gap 15 can thus be set and detected.
    [0031] For example, a plunger coil can be used as the measuring system, which delivers a clear measurement signal by translating the measured path. The moving coil can be arranged in the area of the measuring gap 15 on the frame 16 of the pressure rollers 4a-4c.
    Alternatively, the angle between the measuring gap 15 and the fulcrum 14 can be used to measure via an angle measuring system integrated in the bearing of the fulcrum 14.
    Furthermore, it is possible to adjust the frame 16 of the pressure rollers 4a-4c under pretension, for example a leaf or torsion spring, to the desired size of the measuring gap 15, for example 0.3 mm. Changes in the measuring gap 15 in the continuous cotton 3 thus have a direct effect on the spring, so that the changes in the measuring gap 15 can be determined very precisely by means of strain gauges on the spring.
    As an alternative to the exemplary embodiments described above, the measuring gap 15 can also be arranged between the printing rollers 4a and 4b or alternatively between the printing rollers 4b and 4c. This naturally presupposes an arrangement and mounting of the printing rollers 4a and 4b and 4b and 4c which can be moved relative to one another, wherein each of the printing rollers 4a-4c can be mounted in a separate frame. Here too, for example, a plunger coil or another measuring system can be used to determine the thickness of the cotton 3.
