Definitions

  • the present invention relates to a method for piecing a thread in an open-end spinning device having a spinning element by means of an expert system.
  • the spinning element is fed to the spinning element by means of a feeding device to be spun fiber material, a yarn end fed back into the spinning element and withdrawn the newly spun yarn by means of a take-off device.
  • the feeding device and the drawing device are controlled by a control device of the open-end spinning device, wherein settings for controlling the feeding device and the drawing device are calculated by an expert system from empirical data stored in the control device and from current spinning operation data and piecing data input to the control device.
  • Such a method, in which settings for the workflows that are relevant for the piecing process, are calculated by an expert system is, for example, from DE 103 27 370 A1 known.
  • certain calculation formulas for calculating the relevant settings are stored in a control device.
  • fixed parameters are stored in the control device, which relate, for example, to different materials or to different yarn properties and which are used to calculate the settings by means of the calculation formulas. These parameters were empirically determined based on previous piecing attempts and have proven to be useful in the calculation of settings for high quality approaches. Thus, only current spinning operation data and data concerning the appearance of the piecing-to-be-produced need to be entered into the control device. This then automatically calculates suitable settings for the piecing process.
  • the thread take-off is controlled in dependence on the Auskmmschreib the tuft so that when heavily affected the tuft, the thread take-off speed is increased more slowly than at less impairment. Furthermore, if the tuft is severely damaged, the thread take-off can start later than if it had little effect. In order to determine the combing condition of the tuft, the downtime of the sliver is used with the opening roller.
  • the object of the present invention is therefore to propose a method and a device for piecing a thread, which enable the production of particularly high-quality piecing devices.
  • a yarn end fed back into the spinning element and deducted the newly spun yarn by means of a take-off device In this case, at least the feed device and the discharge device are controlled by a control device of the open-end spinning device. Settings for controlling the feed device and the take-off device are determined by an expert system from empirical data stored in the control device and from current spinning operating data and piecing data entered into the control device.
  • a device for piecing a thread in an open-end spinning device has correspondingly at least one feed device for feeding a fiber material, a yarn return device and a take-off device for removing the newly wound thread. Furthermore, the device has a control device with an expert system, wherein settings for controlling the feed device and the trigger device can be calculated by the expert system and at least the feed device and the trigger device can be controlled by the control device according to the determined settings.
  • the expert system calculates at least one time of occurrence of at least one thin spot, in particular a first and / or a second thin spot, in the piecing table.
  • the calculated time or the calculated times are then used to determine the settings for the control of the trigger and the withdrawal speed of the trigger device is controlled by means of the determined settings such that the at least one thin spot is at least partially compensated.
  • the timing of the occurrence of at least one thin spot in the piecing is accordingly predicted by the expert system and a withdrawal speed of the trigger device controllable such that the at least one thin spot is at least partially compensated.
  • the time of occurrence of a thin point By predicting the time of occurrence of a thin point, it is possible to adjust the amount of fiber in the piecing by adjusting the withdrawal speed comparatively accurate and thereby compensate for the thin points occurring in the piecing much better than before.
  • the time of occurrence of a thin spot can be calculated in relation to a specific, fixed event or time within the piecing process, for example in relation to the release of the thread or for feeding or releasing the fibrous bar at the beginning of piecing.
  • the trigger device is driven by the control device leading to or at the latest at the time of occurrence of the at least one thin spot for a predetermined period of time with respect to an operating withdrawal speed and or against a piecing take-off speed reduced take-off speed. Only after the predetermined period of time, the withdrawal speed is accelerated back to the regular take-off speed for this piecing phase. As a result, the fiber mass is briefly increased in the piecing immediately before or at the occurrence of a thin spot. It has been shown that the fiber mass can be influenced in the piecing without significant time delays by the short-term driving with the reduced take-off speed, so that a particularly accurate compensation of the thin areas is possible.
  • the draw-off device to a relative to an operating withdrawal speed reduced piecing take-off speed is accelerated.
  • the piecing process can thus advantageously be carried out at reduced speeds of the aggregates involved and subsequently the aggregates involved in the piecing process can be raised synchronously to their operating speed or the take-off device to their operating take-off speed.
  • the withdrawal device is first accelerated to a predetermined, first withdrawal speed in a first acceleration phase before reaching the piecing withdrawal speed and / or before the operating withdrawal speed is reached, and then for a first, predetermined period of time with the first Discharge speed is driven. It is thereby possible to start the withdrawal of the newly wound thread after the thread shedding and thus to enable the piecing process and still increase by immediately before or to the appearance of a thin spot, the amount of fiber in the piecing.
  • the reduced withdrawal speed of the draw-off device is kept substantially constant.
  • the tolerance range can be, for example +/- 40% of the predetermined first take-off speed. It is advantageous, however, if the tolerance range is only +/- 30%, and it is particularly advantageous if this is only +/- 20% of the first take-off speed. It is also possible within this tolerance range to specify a time course of the take-off speed. In the piecing occurs a first thick spot, which follows a first thin spot immediately, usually in an overlap region of the returned in the spinning element yarn end with a there already stored Fiber ring on. A second thin spot may also arise following the binding site of this fiber ring. The operation with the reduced, first take-off speed can be used both for compensation of the first and the second thin point.
  • the take-off device is accelerated to a predetermined, second reduced take-off speed after the first predetermined period of time and before reaching the piecing take-off speed and / or before the operating take-off speed has been reached in a second acceleration phase. Subsequently, the trigger device is again driven for a second, predetermined period of time at the second take-off speed.
  • the trigger device for the second predetermined period of time in a narrow tolerance range driven by the second reduced take-off speed. It is thereby possible to compensate for both the first thin spot and the second thin spot in the piecing. It can thus be piecing with particularly high strengths and particularly uniform appearance can be generated.
  • the settings for controlling the withdrawal device determined by the expert system comprise at least one point in time of the start, the duration of the drive with the reduced withdrawal speed and the height of the reduced withdrawal speed.
  • the amount of acceleration in the first and / or in the second acceleration phase and the time of the start of driving with the reduced take-off speed to control the trigger device.
  • the settings furthermore include the magnitude of an acceleration for achieving the piecing take-off speed and / or the operating take-off speed.
  • the take-off device can thus be very exact with respect to the fiber feed be controlled so that a particularly uniform piecing can be generated.
  • the settings for controlling the withdrawal device are determined by the expert system as a function of a material type of a fiber material to be spun and / or the yarn count of the thread. It has been shown that both the length and the expression of thick and thin places are sometimes heavily dependent on these factors. Thus, both the beginning and the duration of driving with the reduced take-off speed and the height of the reduced take-off speed can be matched to the type of material and the yarn character of the respectively produced yarn.
  • the settings for controlling the triggering device are calculated by the expert system on the basis of the entered and the stored data.
  • a plurality of functional curves for the control of the extraction device are stored in the control device.
  • the function curves do not specify individual times or durations, but a course of the withdrawal speed over time.
  • the expert system determines suitable settings for controlling the trigger device by selecting a suitable function curve as a function of the calculated time of occurrence of the at least one thin point.
  • the spinning element relevant, current spinning operating data in particular a rotor circumference, are taken into account. Since the first and the second thin spot occur at characteristic points in the piecing, this is a particularly good precalculation of the time of occurrence of thin sites possible.
  • the settings determined by the expert system for controlling the feed device comprise at least the direction of rotation and the time start and the end of time of accelerations of the feed device. These settings are taken into account in the calculation of the at least one thin spot in the piecing. In conjunction with the current spinning operation data entered into the control device and the piecing data, thin areas can be calculated exactly in advance and the yarn withdrawal can be controlled accordingly.
