Definitions

  • the invention relates to a workstation of a textile machine producing cross-wound bobbins with a thread guide channel which surrounds a thread feed device, in particular a feed bobbin positioned in unwind position, and a winding device of the work station and a plurality of bearing housings and / or bearing sections for installing various thread treatment and thread monitoring devices. in particular a thread splicing device.
  • the jobs of these widely used in the textile industry textile machines generally each have a yarn path, which is largely open at least forward and thus well visible to the operator.
  • the yarn withdrawn from a spinning cop positioned in an unwinding position travels through different crosshairs, such as a bobbin thread, on its way to a cross-wound bobbin in a winder Thread tensioner, a thread cleaner with a thread trimmer, a yarn tension sensor and optionally a waxing device, but remains largely visible.
  • Such trained jobs are further each equipped with a thread connecting device, preferably with a pneumatically operated Fadenspl sandwichvoriques, a pneumatically actuated suction nozzle and a pneumatically acted upon gripper tube.
  • the suction nozzle and the gripper tube are connected to a textile machine's own vacuum system and ensure after a thread break or a controlled thread cleaner cut that recorded on the cheese package end of the upper thread or fixed in the thread tensioner thread end of the lower thread is received and transferred to the Fadensl alonevorraum.
  • the two yarn ends are further cleaned, exactly cut to length, prepared and properly positioned in the splicing channel of the splicing prism of the yarn splicing apparatus before the splicing process.
  • the work stations can each have a closed thread guide channel, which is in each case equipped with a plurality of bearing sections or bearing housings in which different thread monitoring and treatment devices are installed.
  • Fadeneritkanal By integrating the various Fadenüberwachungs- and treatment facilities in the thread running path enclosing Fadenleitkanal is also achieved that the current thread is largely encapsulated during the winding process against the environment, which has a very positive effect especially with regard to the development of dirt at the workstations.
  • a disadvantage of jobs with such a closed Fadenleitkanal is, however, that the thread runs largely concealed on its way from the spinning cop to the cheese for the operator and therefore it is neither controllable for the operator, whether the current thread on its way to the winding device, the thread monitoring devices always passes properly, nor whether the thread splicer works properly. That is, it is neither comprehensible to the operator, whether the thread was properly monitored before winding on the cheese, or if proper Fadenspl devise were created if necessary.
  • the yarn splicing device is not only arranged, as is usual with closed yarn guide channels, in a relatively concealed manner in a bearing housing, but the bearing housing is also covered, at least partially, by the round magazine. That is, especially in jobs that have a closed Fadenleitkanal and are also equipped with a round magazine, the splicing prism and thus the splice of the Fadensleiißvorraum is barely visible.
  • an image pickup device for.
  • the digital image data are fed to an evaluation computer and evaluated by this to the effect that the presence of thread residues on the spinning head sleeve can be assessed.
  • the service unit in this case has a camera which is set up to generate images of the service unit and / or the workstations and to transmit them to a control and computer unit of the textile machine.
  • the control and processing unit processes the transmitted information and uses it to control the service unit and / or to operate and / or control a pending job.
  • the present invention seeks to modify a job of a cheese-producing textile machine having a closed Fadenleitkanal to the effect that the operation of a Faden awarenesss- or thread monitoring device for the operator is traceable and correctable if necessary.
  • the thread guide channel has a monitoring section in the region of a bearing housing or bearing section accommodating a thread treatment device or thread monitoring device via which monitoring of the thread treatment device or thread monitoring device installed in the bearing housing or bearing section can be performed by means of an optical linkable to a computer device Recording device can be realized.
  • Fadenleitkanal Faden adaptations- or thread monitoring devices can now be checked on your operation and functionality, if necessary, continuously, periodically or at defined times by the operator or automatically by an analysis device, for example.
  • an analysis device for example.
  • a computer device In the form of a computer device.
  • At least or only the at least one monitoring section of the yarn guide channel is designed to be transparent, wherein the optical recording device can be arranged or arranged at the monitoring section or at a distance therefrom. More preferably, the Fadenleitkanal be formed predominantly or completely transparent.
  • a predominantly transparent design is present when the yarn guide channel is designed to be transparent not only to monitoring sections for monitoring the yarn treatment or yarn monitoring devices, but also to different sections thereof. As a result, not only the corresponding device but also an interior of the thread guide channel can be monitored in regions outside the installed device.
  • the yarn guide channel can exclusively have at least one transparently formed monitoring section.
  • different sections of Fadenleitkanals are thus formed in a non-transparent manner.
  • a light incidence or other optical interference influences can be avoided in the Fadenleitkanal.
  • the yarn guide channel may preferably have corresponding mounting aids, such as, for example, fastening and / or locking means.
  • the monitoring section can form a receptacle for the optical recording device.
  • the optical recording device can be suitably arranged on the monitoring section and more preferably be mounted in a stationary manner by providing corresponding fastening and / or locking means.
  • the transparent configuration of the monitoring section can be provided such that an unadulterated insight into the Fadenleitkanal or to the corresponding associated Faden awarenesss- or thread monitoring device is made possible.
  • the transparent monitoring section is designed such that distortions, optical reductions or optical magnifications (magnifying effect) are avoided. If, for example, an enlargement should be required, such could be realized by means of the optical recording device, since this either itself means for reducing or enlarging the image to be recorded or the recorded image can be provided by the optical recording device in an appropriate manner on the software editable.
  • the optical recording device which can be connected to a computer device is arranged in or on the monitoring section in the region of a bearing housing or bearing section which can be used to monitor at least the splicing process and, in particular, the work result of the splicing prism of the yarn splicing device.
  • This embodiment has the particular advantage in the course of, for example, the formation of a so-called pilot job that can be prevented in a relatively simple manner that the Fadenspl divoridesen the jobs of a cheese, for example, due to incorrect setting of the yarn splicer, undetected create thread connections that do not comply with the requirements.
  • the yarn splicing apparatus may be protected and arranged for operators almost inconspicuous in a bearing housing of a closed Fadenleitkanals takes place during the splicing process instead of monitoring the Fadens splitting device, the result of this monitoring by the operator visible and thus controllable.
  • each of the numerous work stations of a textile machine is designed as described above.
  • the optical recording device is in each case designed as a video camera.
  • a relatively inexpensive video camera has the advantage that in such a camera, in contrast to a film camera for example, the recorded images are stored in the form of electronic signals.
  • the electronic signals can be easily and inexpensively displayed as images on the monitor of a downstream computer device.
  • a downstream computer device on the monitor which are made visible by the optical recording devices images can be used in an advantageous embodiment either the central control unit of the textile machine or a portable tablet or laptop, which can be connected alternately to the optical recording devices of the numerous jobs of the textile machine is.
  • Both the central control unit of the textile machine and a portable tablet or laptop each have a monitor on which the images produced by the optical recording devices can be displayed and thus checked by the operating personnel.
  • the images of the optical recording devices in the computer device are also analyzed in a yarn-specific manner. That is to say, the computer device checks on the basis of the known yarn data and the images produced by the optical recording devices whether the splicing parameters correspond to the splicing parameters which should be used during the processing of the present yarn section.
  • the checking and analysis of the yarn data with the recordings of the optical recording devices can take place either constantly or regularly.
  • a review and analysis of the yarn data and the recordings of the optical recording devices is particularly advantageous when a Garnpartie touchscreen has taken place, since such a Garnpartie LCD often can make a correction of the originally set splicing parameters necessary. That is, based on the analysis produced in the computer device, different splice parameters can be optimized if necessary; For example, a correction of the catchment length of the thread ends to be spliced into the splice channel of the splicing prism can take place.
  • FIG. 1 shows schematically, in perspective view, a job 1 of a cross-wound producing textile machine, in the embodiment, a winding unit of a so-called cross-winding machine.
  • Such cross-winding machines are known to have a variety of such, mostly identical trained jobs 1 on which supply bobbins, usually produced on ring spinning machines spinning cops 2, which have relatively little yarn material, are rewound to large-volume cheeses 5.
  • the finished cheeses 5 are then transferred by means of a (not shown) automatically operating service unit, for example by means of a so-called cheese change on a machine-spooled cross-bobbin transport device of the cheese and transported from this to a machine end side arranged Spulenverladestation or the like.
  • the jobs 1 of such automatic packages can each be equipped with a round magazine in which a plurality of spinning cops are then stored.
