Description

  The present invention relates to a winding machine for manufacturing a plurality of twill-wrapped packages rotatably held by a package frame, and a semi-automatic twill-wrapped package manufacturing textile machine including a plurality of working units each having a working unit control device. .

  Semi-automated twilled package manufacturing textile machines typically consist of a plurality of similar work stations arranged in rows. Semi-automatic textile machines always also require manual support, at least in part. This is the case, for example, with a winder having a rotary magazine. In machines of this type, the supply of the yarn material to the take-up location takes place, for example, via a take-up location-specific spin cup magazine, which is configured as a so-called rotary magazine. The rotary magazine itself has to be installed manually by the operator, but the subsequent distribution of the spinning cup to each winding point is automatic.

  In a semi-automatic rotor spinning machine, a twill winding package is manually replaced with an empty tube, whereas in a spinning machine in which a rotary magazine is manually loaded, even if the twill winding package is automatically replaced. In the sense of the present invention, it is called a semi-automatic winder.

  Furthermore, such a semi-automatic twilled package manufacturing spinning machine has a central control unit and a vacuum system specific to such a machine. The individual working units have, in particular, so-called winding devices, these winding devices comprising a package frame for rotatably holding the twill package and a drive for rotating the twill package. And a yarn traversing device for traversing the yarn to be wound into the twill winding package. Such a winding device is, for example, a rotor spinning machine, which allows winding of a twill-wound package in connection with a spinning station. However, the winding machine also has such a winding device, in which a spinning cup having a relatively small amount of yarn material is rewound into a large-capacity twill package in the working section. In this case, the yarn supply is not a spinning station but a storage bobbin.

  In a semi-automatic open-end rotor spinning machine, for example, the stored sliver is supplied to a defibrating roller by a sliver pull-in cylinder, and the defibrating roller defibrates the sliver into individual fibers by its needle cloth, and the yarn of a spinning box. It is transported to the guide passage. This fiber transport is assisted by a negative pressure in the rotor casing, which creates an air flow in the yarn guide passage, defibrate the yarn from the defibrated garment, and pass the yarn through a so-called passage plate adapter. To the spinning rotor as expected. Due to the acceleration due to the centrifugal force, the yarn slides into the collecting groove of the spinning rotor, where it is collected, pulled out in the axial direction by the drawing nozzle of the rotating shaft, twisted into one yarn, and wound around the twill package. It is.

  Each of the spinning or winding devices is connected to a working unit control device. The individual working unit controls themselves are in some cases connected via a section control unit to the central control of the semi-automatic open-end rotor spinning machine.

  Semi-automatic twill wound package manufacturing textile machines have been used in various embodiments in the spinning industry and are described in detail in numerous patent specifications.

  An open-end rotor spinning machine with a widely autonomous working unit is known, for example, from EP 1 283 288 A1.

  Each working unit of the textile machine has a plurality of individual driving units, and these individual driving units can be automatically repaired in the event of a failure. For this purpose, these working units have, in addition to the suction nozzles, which are driven by individual motors specific to the spinning station, in particular also individual drives for the yarn traverse device, for the package drive rollers and for the yarn pull-out device.

  German Patent Application DE 198 36 065 discloses a so-called automatic open-end rotor spinning machine, in which both the working mechanism of the spinning device and the working mechanism of the winding machine are driven by drive means of machine length. Being driven.

  In the area of the spinning device, a tangential belt for driving a spinning rotor and a defibrating roller and a drive shaft of a machine length for driving a sliver pull-in cylinder are arranged, and the corresponding drive is a machine end. Attached to the machine frame located on the side.

  In the area of the take-up device, a take-up drive roller is arranged on a take-up drive shaft of machine length and a plurality of traverse yarn guides connected to a traverse drive arranged at the machine end. Are fixed to a reciprocating yarn guide rod.

  In addition, a yarn pull-out device is provided, the pull-out roller on the driving side of which is also a component of the mechanical length drive shaft.

  The working unit of such an open-end rotor spinning machine is maintained by a service unit, which patrolls along the working unit, for example, if one of the working units fails. Automatically intervenes.

  DE-A-43 09 947 describes a so-called semi-automatic open-end spinning machine. The working section of this semi-automatic open-end spinning machine preferably has a sliver pull-in cylinder that can be driven by one individual motor, whereas, for example, a spinning rotor, a defibrating roller and a package driving roller. , Can be driven by driving means of machine length. In addition, a working part control device is provided, which stops the corresponding working part after a fault, for example after a yarn break. An auxiliary operation is manually performed before the piecing process is actually started, and then the actual piecing process is started by the working unit control device.

  Semi-automatic open-end rotor spinning machines are relatively cost effective and high performance textile machines. This is because costly service units are not used here and each working unit is not configured autonomously. However, semi-automatic open-end rotor spinning machines have the disadvantage that only one yarn party can be produced on each machine side and are therefore relatively inflexible.

  In order to assist the operator of such a semi-automatic open-end rotor spinning machine during operation, in particular in changing the twill packages / empty tubes, DE-A-102008003704 discloses a semi-automatic system. A method for operating a working part of an open-end rotor spinning machine or a working part for carrying out this method is described. According to this patent specification, each working part of the semi-automatic open-end spinning machine is operated from a distance even when it reaches a preset yarn length at the end of the winding process of the twill winding package. Indicated by a signal that can be sensed by personnel.

  However, the above-described working unit and method of the semi-automatic open-end rotor spinning machine can be operated only by inquiring of the working unit control unit or the central control unit whether the same or different yarn parties are produced on both machine sides. It has the disadvantage that it is not shown to members.

EP 1 283 288 A1 DE 198 36 065 A1 German Patent Application Publication No. 43 09 947 German Patent Application Publication No. 102008003704

  The object of the present invention starting from the above-mentioned prior art is to provide a semi-automatic twill-wrapped package manufacturing fiber machine which is cost-effective and has a high performance. The aim is to further optimize the assistance of the operator by means of the machine and to achieve a high degree of flexibility.

  According to the invention, the above-mentioned object is achieved by a characteristic arrangement according to the characterizing part of claim 1, which relates to a semi-automatic twill-wrap packaging production textile machine.

1 shows a semi-automatic open-end spinning machine according to the invention. FIG. 3 is a side view showing a working unit of the semi-automatic open-end spinning machine according to the present invention. FIG. 7 is a front view schematically illustrating another embodiment of the working unit according to the present invention.

  Advantageous embodiments of the invention are set out in the dependent claims.

  The advantages provided by the present invention are, in particular, the fact that the display means of the working unit can always be seen from a distance to the operator, so that it is possible to continuously determine which working unit is producing the same yarn party. To be displayed.

  The plurality of light signals of the display means are significantly different from each other, so that the operator can identify from a distance which work unit belongs to which yarn party.

  This allows the operator to determine in a timely manner an advantageous sequence for the processing of the waiting tasks without any additional costs, which is greatly assisted in optimizing the travel path.

  The minimization of the above-mentioned travel path resulting from the "intelligible" sequence results in a reduction in downtime of the individual working units and thus an increase in the efficiency of the semi-automated twill package manufacturing textile machine. .

  Advantageously, for the display means, use is made of, or extends, existing equipment for the textile machine, for example a signal lamp or thread clearer, which is arranged above the working part. be able to.

  As described in claim 2, the semi-automatic twill-wrapping production textile machine according to the invention has, in particular, yarn groups which are grouped together with a plurality of groups, which are independent of the other groups. In the control, at least one of the functions of the clearer setting, the piecing device setting, the sliver supply, the package diameter, the fineness, and the effect setting is different.

  Thus, a plurality of yarn parties can be simultaneously manufactured in one semi-automatic twill-wrapped package manufacturing textile machine, and the same color is displayed, for example, by the display means of the working unit in which the same drive control is performed.

  The size of the above groups, or more precisely, the number of working units producing the same yarn party, is variable and controllable on demand. The minimum number of one yarn party includes one working unit. For example, on one machine side of the semi-automatic twill winding package manufacturing textile machine according to the present invention, the first yarn party is operated in the working units 1 to 50, the second yarn party is operated in the operations 51 to 240, and On the machine side, the third yarn party is manufactured by all working units (working units 1 to 240).

  For example, in a semi-automatic open-end rotor spinning machine, predetermined parameters such as a rotor speed, a traversing angle of a yarn to be wound, a rotation or a winding stroke, etc. The same for the working units, but in the present invention some functions can be selected and adjusted independently of the other working units by corresponding parameters, which are described in more detail below.

  The ability to flexibly select the clearer limits for different working sections allows a plurality of yarns to be produced that meet different quality requirements. If the above-mentioned clearer limit is chosen very loosely, relatively few clearer cuts are performed, i.e. the productivity is improved and a yarn with non-uniformity due to manufacturing is obtained. If, on the other hand, the above-mentioned clearer limit is adjusted rather narrowly, more clearer cuts are carried out and a very uniform yarn is wound up into a twill package.

  The parameters to be set for the piecing device are the same as those for the clearer setting. The piecing device settings can be varied from very precise adjustments to coarse adjustments, resulting in very uniform or even non-uniform yarns.

  The package diameter to be achieved or the take-up yarn length to be achieved in the twill package is generally of a size preset by the customer and ultimately determines how many yarns will be wound into each twill package. Thus, with this variable choice, a plurality of twill packages with different diameters or yarn lengths can be produced simultaneously.

  By controlling the sliver pull-in cylinder, it is possible to simultaneously produce finer and correspondingly coarser yarns in the working stations belonging to one yarn party than in the working stations of the other yarn party. If the sliver pull-in cylinder is driven slowly, fewer yarns will be conveyed to the defibrating roller and finer yarns will be obtained than if more yarns were fed to the defibrating roller at the same time.

  Similarly, via the control of the sliver retraction cylinder, each work station can set whether to produce standard yarns or effect yarns. To obtain an effect yarn, the sliver retraction cylinder described above can be driven, for example, by different speeds at more or less regular intervals. When many yarns are supplied to the defibrating roller, a "thick portion" is obtained, and when a small amount of yarn is conveyed to the defibrating roller, a "thin portion" is obtained similarly.

  In summary, it can be seen that this allows a plurality of different yarn parties to be produced simultaneously on one semi-automatic open-end rotor spinning machine. The plurality of yarn parties differ in one of the plurality of functions described above or in a combination of various different functions.

  Semi-automatic winders also allow clearer settings or package diameters to be set separately for each party. However, in general, different yarn parties differ from each other by different storage materials.

  This means, for example, that in one semi-automatic take-up machine, a spinning cup of one party is rewound, and this spinning cup has a different fineness and / or a spinning cup of another party. Or having another material. In an advantageous embodiment of the invention, at least two groups are configured per machine side, as described in claim 3, that is to say that a total of at least four yarn parties are produced in one semi-automatic twill package. Can be manufactured on textile machines. This allows the manufacturer to flexibly respond to customer needs and quickly produce a plurality of different yarn parties. Here, relatively small yarn parties can also be produced, in particular with the semi-automatic open-end rotor spinning machine according to the invention. This is because it is not necessary to stop the remaining working part and one or more different yarn parties can be produced at the same time, so that this open-end rotor spinning machine can be produced economically in the end.

  According to claim 4, the display means is advantageously connected to a plurality of working unit controls, which display different indications relating to the yarn party. Are configured to trigger.

  These display means are connected to the plurality of working unit control devices via signal lines, and are driven and controlled by these working unit control devices in relation to the yarn party. This means that a plurality of working units having the same manufacturing parameters constitute one group and are displayed the same.

  As described in claim 5, the plurality of working unit control devices are connected to a host central control device via a single bus, and the control devices of each of the groups are connected via the central control device. Input and / or assignment of control data to.

  With this structuring, it is ensured for the entire semi-automated twill package production textile machine that the central control unit drives the individual local working unit controls. This is because the individual work unit controls are connected to this central control unit. This means to the operator that all the control data for the above-mentioned yarn parties are located at one fixed point, typically at the edge of a semi-automatic twill package manufacturing textile machine. Is to be entered.

  In another advantageous embodiment according to claim 6, the work station control is configured for inputting control data.

  It may also be advantageous to input the control data locally at each work unit to the work unit control device. This minimizes the amount of data to be transmitted between the central control unit and the local control units.

  The present invention will be described in detail below based on an embodiment of a semi-automatic open-end rotor spinning machine shown in the drawings.

  FIG. 1 schematically shows a front view of an open-end rotor spinning machine 1 having so-called end frames 52, 53. Although not shown in detail because they are known, these end frames are provided, for example, with feed-through feed and discharge channels, which are negative pressure channels for supplying a spinning vacuum to the spinning device, as well as electronics for the bus system. It is connected via a channel and / or a yarn monitoring device and a cable channel for supplying electrical energy to the working part 2.

  In the above-mentioned supply and discharge channels, which are a "backbone" in a sense of this spinning machine, the open-end spinning machine 1 recognizes the yarn-forming or traversing-package-winding device which constitutes a plurality of normal working sections 2. be able to.

  In the working unit 2, the storage sliver stored in the spinning case 28 is spun into a yarn, which is wound around the twill winding package 22.

  On the end frames 52 to 53, for example, a negative pressure supply device (not shown) specific to the spinning machine of the open-end rotor spinning machine 1, an electric energy supply unit, and a central control unit 41 are arranged.

  The central control unit 41 itself is preferably connected to the work station control 9 via a bus system 42.

  FIG. 2 shows a working section of a semi-automatic open-end rotor spinning machine 1 according to the invention in a side view.

  Each working unit 2 has one spinning device 3 and one winding device 33. Furthermore, signal lamps 44 are provided on or on each work unit 2, which can display signals of different colors, and whose protruding arrangement allows the operator This is very well sensed from farther away.

  As described above, in the spinning device 3, the slivers 34 stored in the spinning case 28 are respectively spun into one yarn 30, and the yarn is wound around the twill winding package 22 in the winding device 33. For this purpose, the winding device 33 comprises, as is known per se, a package frame 21 for rotatably holding the winding tube of the twill winding package 22, a package driving roller 23, a yarn traversing device 26, It has one device 7 and one device 7 for lifting the twill winding package 22 from the package driving roller 23.

  The device 7 is, for example, configured as an extrusion piston drive, which is connected to a positive pressure source (not shown) via an air line 24 inserted in a solenoid valve 17.

  The driving unit of the package driving roller 23 is configured as a group driving unit. This means that a mechanical length drive shaft to which the individual package drive rollers 23 are fixed is provided.

  The spinning device 3 substantially has a spinning rotor 4, a defibrating roller 12, and a sliver pull-in cylinder 14, as is known.

  The spinning rotor 4 is supported, for example, by a support disk bearing 5 and is driven by a tangential belt 6 of machine length. In order to detect the number of revolutions of the spinning rotor 4, a sensor device 8 can be further provided, and this sensor device is connected to the working unit control device 9 of the working unit 2 via a signal line 40.

  The defibrating roller 12 is preferably driven by a tangential belt 13, also of machine length, whereas the sliver pull-in cylinder 14 is individually motor-driven by a drive 15.

  The drive unit of the sliver retraction cylinder 14, for example, the stepping motor 15 is similarly connected to the working unit control device 9 via the control line 16.

  Further, each of the working units 2 has a sliver pullout device 18 driven by a machine length, and the sliver pullout device is connected to the working unit control device 9 via a control line 20 and a sliver pulling device when viewed in the yarn traveling direction. It is connected to a thread storage device 37 located behind the drawer device 18.

  The yarn accumulator 37 is preferably configured as an air-operated accumulator nozzle, which is connected via an air line 38 to a negative pressure source (not shown).

  In the embodiment shown, the working part control device 9, which in particular controls the drive part 15 of the sliver retracting cylinder 14, is furthermore connected via a signal line 29 to a switch element 27, which, if necessary, is connected, for example, to a thread. It can be operated by the service unit 10 to start the splicing process. This service unit performs necessary auxiliary work in cooperation with the piecing process.

  The corresponding service unit 10 is supported on a machine-length travel rail 31 or 32 by a travel mechanism 11 or an auxiliary wheel 25 and can be positioned, if necessary, on the working part 2 where the piecing operation is to be performed.
