Definitions

  • the invention relates to a textile machine with a large number of similar work stations, which are each equipped with a signaling device, by means of which an operating requirement for a work station can be indicated.
  • an automatic cheese winder in which a display is arranged in the paneling of each winding unit, which displays the type of error.
  • the display is designed in such a way that it contains a few translucent individual images of possible defects, each of which is assigned a light source that can be controlled individually by the workstation computer of the workstation concerned.
  • a method for operating a work station of a semi-automatic open-end rotor spinning machine is known, which is intended to provide helpful support for the operating personnel during operation, in particular when changing cheeses/empty tubes.
  • each of the numerous work stations of the semi-automatic open-end rotor spinning machine has a signaling device that can be perceived by the operating personnel Reaching a predetermined thread length indicates.
  • a flashing signal is generated at the work station, which has an increasingly high frequency as the specified thread length of the cheese is approached.
  • a steady light indicates that the specified thread length has been reached at this work station and production has stopped.
  • a ring spinning machine whose spinning positions are equipped with sensor devices that monitor the proper operation of the spinning positions is also in the DE 196 42 222 A1 described.
  • the spinning positions are each equipped with an optical display device that flashes when there is a fault at one of the spinning positions.
  • the DE 10 2014 018 628 A1 describes a textile machine that has a large number of similar jobs, each of which has a display device.
  • the display means of the work stations are connected to the central control device of the textile machine and are designed as LED light rails. This means that at each work station, the yarn batch produced and/or the operating status of the work station are displayed using certain sections of the LED light bar.
  • the object of the invention is to optimize the operation of textile machines that have a large number of similar work stations. This means that the operating personnel, regardless of where they are in the area of the textile machine, should not only be informed immediately that there is a fault at one of the work stations, but should also be able to recognize immediately in which area of the textile machine the affected work station is located.
  • this object is achieved in that the signaling devices are arranged and controllable at the work stations in such a way that, if necessary, they form rows of running lights that run from the work stations, which are arranged at the machine ends of the textile machine, to the work station requiring operation.
  • the configuration according to the invention has the particular advantage that the operating personnel, regardless of which area of the textile machine they are in at the moment, are not only made aware that one of the work stations indicates a need for service, but the operating personnel are also immediately shown in which In the direction of the multi-point textile machine, the job that requires service can be found, with the job in question being identified by the meeting point of the rows of running lights. This means that the rows of running lights allow the operating personnel to intervene more quickly, which is very advantageous because work stations that are idle or produce inferior quality mean loss of production or less yield.
  • the signaling devices of the work stations are connected to the central control unit of the textile machine.
  • the signaling devices can preferably be controlled in a defined manner by the central control unit of the textile machine in such a way that if one of the work stations requires manual intervention by the operating personnel, rows of running lights are initiated immediately, which run in the direction of the work station requiring service.
  • the operating personnel are not only informed immediately that one of the work stations of the multi-station textile machine is being used, but the operating personnel are also immediately shown the area of the often long textile machine in which the work station requiring service is located.
  • the required walking distances of the operating personnel can be significantly improved or optimized by the running light rows according to the invention.
  • the signaling devices are formed by LED lamps, which are arranged in the area of the work stations of a long textile machine in such a way that at least one of the running light rows is always clearly visible to the operating personnel.
  • the signaling devices can always be easily perceived by the operating personnel or cannot be overlooked.
  • an arrangement of the signaling devices on the winding unit housings at about eye level is advantageous, since the signaling devices are then clearly visible from the operating aisle located in front of the automatic cheese winder.
  • an arrangement of the signaling devices in the lower area of the work stations for example in the area of the frame edge of the bobbin return section, can also be advantageous.
  • Such an arrangement has the advantage, for example, that a continuous LED light bar can be used instead of a large number of individual LED lights.
  • LED illuminants are to be understood as meaning different LED variants, including OLEDs, for example. That is, regardless of the density of LEDs per unit length, the Signaling device can be designed as a flexible or rigid LED light source and can be available, for example, in one or more rows. Light guides should also fall under the term "LED light source" chosen for simplification. Above all, it is important that such LED lamps are arranged so that they are clearly visible to the operating personnel, so that the operating personnel are informed immediately at any time if manual intervention is necessary at one of the work locations and at which of the work locations.
  • the signaling devices working according to the invention are preferably arranged at the work stations of automatic cheese winders or at the work stations of open-end rotor spinning machines.
  • use of the signaling devices according to the invention is also conceivable in connection with other multi-point textile machines.
  • the signaling devices can also be used, for example, at the work stations of ring spinning machines, air-jet spinning machines, etc.
  • the figures 1 and 2 show exemplary embodiments of textile machines 1, each of which has a large number of work stations 2 or 41 arranged next to one another in a row.
  • the work stations 2 and the work stations 41 of the textile machines 1 are each identical in design.
  • figure 1 is a side view of one of the numerous juxtaposed jobs 2 of a cheese-producing textile machine 1, a cheese-winding machine 10, while the figure 2 shows a textile machine 1 producing cross-wound bobbins in the form of an open-end rotor spinning machine 30 in a front view.
  • spinning cops 3 which were produced on ring spinning machines connected upstream in the production process and which have relatively little yarn material, are rewound into large-volume cross-wound bobbins 4 at the work stations 2 of automatic cheese winders 10, with the thread 5 running off the spinning cop 3 also being checked for thread defects during the rewinding process is monitored and cleaned immediately.
  • the cross-wound bobbin 4 is held freely rotatably during the winding process in the bobbin frame 6 of a winding device 32 and is rotated, for example by a thread guide drum 7, with a friction fit.
  • the thread guide drum 7 also ensures that the thread 5 unwound from the spinning cop 3 is properly traversed as it runs onto the cross-wound bobbin 4 .
  • FIG figure 1 The thread treatment and monitoring devices required in connection with the winding of cross-wound bobbins 4 or the cleaning out of thread defects from the thread 5 are essentially known and are therefore described in FIG figure 1 shown only schematically.
  • the individual work stations 2 of an automatic cheese winder 10 each have different devices, for example a suction nozzle 9 that can be moved about a pivot axis 8 and that can be subjected to a vacuum, a gripper tube 12 that can be moved about a pivot axis 11 and that can be subjected to a vacuum, and a pneumatic yarn splicing device 13.
  • These are known per se Devices are each connected via corresponding control lines to a workstation computer 14, which in turn is connected, for example via a bus system 15, to the central control unit 16 of the cheese-making machine 10.
  • the automatic cheese winder 10 also has a logistics facility in the form of a bobbin and tube transport system 17, from which figure 1 only the cop feed section 18, the storage section 19, which can be driven reversibly, one of the transverse transport sections 20 leading to the work stations, and the sleeve return section 21 are shown.
  • this cop and tube transport system 17 which is usually connected to a comparable cop and tube transport system of a ring spinning machine, spin cops 3 or unwound empty tubes revolve, positioned on transport plates 22 in a vertical orientation.
  • the fresh spinning cops 3 delivered by the ring spinning machine are positioned in unwinding positions AS, which are located in the area of the transverse transport sections 20 of the work stations 2, and then rewound onto a large-volume cross-wound bobbin 4.
  • the automatic cheese winder 10 is also equipped with a signaling device 23 designed and operating according to the invention.
  • a signaling device 23 designed and operating according to the invention.
  • each of the numerous workstations 2 arranged next to one another in a row has a signaling device 23, for example in the form of an LED light source, which is arranged and controllable in such a way that, if necessary, i.e. if one of the workstations 2 of the automatic cheese winder 10 A need for action arises, series of running lights can be initiated.
  • the signaling devices 23 are clearly visible, for example arranged at about eye level on the winding unit housing 24 of the work stations 2 of the automatic cheese winder 10 and connected to the associated work station computer 14, which in turn, as already indicated above, communicates via a bus system 15 with the central control unit 16 of the automatic cheese winder 10 connected is. If necessary, the signaling device 23 of the work stations 2 of the automatic cheese winder 10 is controlled in such a way that two running light rows are initiated, each starting from the work stations 2 of the automatic cheese winder 10 arranged at the machine end. These rows of running lights run towards the work station 2 requiring service, with at least one of the rows of running lights always being immediately visible to the operating personnel, regardless of their respective location in the area of the automatic cheese winder 10 .
  • the figure 2 shows a schematic front view of an open-end rotor spinning machine 30 with a large number of identical work stations 41 arranged between end frames 25, 26.
  • various supply devices are installed in the end frames 25 and 26, for example a vacuum source 27, an electrical energy supply 28 and the Central control unit 29 of the open-end rotor spinning machine 30.
  • the central control unit 29 is in turn connected to the workstation computers 35 of the individual workstations 41, for example via a bus system 34.
  • 31 slivers 37 which are each stored in sliver cans 38, are spun into threads 39 at the workstations 41 by means of the open-end spinning devices 31, which threads are then wound up on the winding devices 32 to form cross-wound bobbins 40.
  • the sliver cans 38 are each positioned below the work stations 41 arranged in a row next to one another.
  • Such open-end rotor spinning machines 30 can also be provided with service runners that can be moved along the work stations 41, for example so-called cross-bobbin changers 42, be equipped, the finished cheeses 40 change to fresh cheese tubes if necessary.
  • the numerous work stations 41 of the open-end rotor spinning machine 30 are also equipped with a signaling device 23 which, if necessary, can be controlled in such a way that two rows of running lights are created which, each at the work stations 2 of the open-end rotor spinning machine 30 arranged in the area of the machine end frames 25, 26 starting, run to the work station 2 that requires service.
  • LED light sources are used as signaling devices 23, which are clearly visible, for example on the work station housings 36 of the work stations 41.
