Definitions

  • the present invention relates to a spinning machine, in particular an open-end spinning machine, with a multiplicity of spinning positions, each of which has a multiplicity of electrically controllable elements, and with a maintenance device which can be moved along the machine and which in each case relates to the elements to be controlled in its working area located spinning stations can be electrically coupled.
  • Such a device which can either be removed from the machine and placed on the machine again at the desired spinning position, or which can be moved on rails along the machine, the connection of the device at the desired spinning point by means of a plug is produced with the electrically controlled elements (DE-AS 2.351.458).
  • This device must be brought by hand to the spinning station to be serviced and also works manually.
  • this device is also quite complicated to use because of the electrical connection that is to be made in each case and later to be released again with the aid of the plug.
  • Fully automatic maintenance devices are also known which run along the machine and feel the thread monitor, which has dropped due to a thread break, whereupon the maintenance device stops at the relevant spinning position (DE-OS 2,714,353).
  • the maintenance device has a signal receiver and a control transmitter, each of which is assigned a control transmitter and a signal receiver of the spinning station. These control connections, which can also be replaced by plug connections, must be provided again at each spinning station.
  • the object of the present invention is to provide a device which enables simple and safe electrical coupling between a maintenance device which can be moved along the spinning machine and the spinning station to be serviced.
  • a collecting line for similar, electrically controllable elements of a plurality of spinning stations and a switching device per spinning station are provided, which can be actuated depending on the position of the maintenance device and the different, electrically controlled elements one Connects spinning station with the associated manifolds with which the maintenance device is in constant connection.
  • This constant connection of the movable maintenance device to the machine-side collecting lines means that neither complicated detachable plug connections nor contactless transmitter and receiver devices are required per spinning station.
  • a switching device provided per spinning station which can be actuated as a function of the position of the maintenance device, simply connects the individual elements of a spinning station with their collecting lines and thus also with the maintenance device at the required time. In this way, the contact connections or contactless connections between the spinning station and the maintenance device, which have so far been produced per spinning station, are eliminated, which considerably simplifies the control device and transmission with the same precision.
  • a further simplification of the subject matter of the invention is achieved in accordance with a further feature of the invention in that the collecting lines can be connected alternately either to evaluation devices arranged in the maintenance device or to control devices. In this way it is possible to scan and evaluate the working status of an element via a specific bus line and, if necessary, to issue a control command for a specific work of the element concerned. This eliminates the need for separate devices for scanning and controlling an element, since the desired operation of the corresponding element can be effected by changing the sampled signal.
  • the maintenance device expediently has one. your leading device in the direction of movement for the switching devices of the individual spinning stations, since then, taking into account the inertia of the maintenance device, timely stopping of the same and safe maintenance, linked to the desired ' spinning station, of the relevant spinning station is guaranteed, even if the maintenance device is normally, that is to say in the absence of one Errors, travels along the individual spinning positions of the spinning machine without interrupting travel. If it is provided that the maintenance device does not or not only orbits the machine, such a leading actuating device is advantageously provided for each direction of movement, which can be placed alternately in or out of operation depending on the change in direction of the maintenance device.
  • the maintenance device has, in addition to the leading actuating device, a further actuating device for the switching devices, which takes effect in the working position of the maintenance device.
  • the subject of the invention only requires a single signal transmission point between the machine and the maintenance device and the maintenance device and the machine above it is never interrupted.
  • the required connection of this maintenance device takes place, controlled from this, by actuation of a switching element provided at the spinning station, which can be effected in a simple manner by touch or also without contact.
  • the scanning time can be increased in a simple manner by simply dimensioning the actuating device (switching cams, switching lugs for contactless switches) accordingly large. As a result, the state of the individual spinning positions can be scanned at a relatively high speed of the maintenance device traveling along the machine.
  • a spinning machine 1 is shown schematically, along which a maintenance device 2 can be moved alternately in the direction of arrows 3 and 30.
  • the spinning machine has a large number of spinning positions, of which four spinning positions 10, 11, 12, and 13 are shown.
  • Each spinning station 10, 11, 12 and 13 has a large number of elements which can be controlled electrically.
  • a control magnet 4 (FIG. 2) is provided for the fiber feed for each spinning station and is controlled by a thread monitor 40.
  • a length counting device (not shown) can also be provided for the bobbin for counting the thread length wound there, in order to replace the bobbin with an empty tube when a specific size of the bobbin is reached, measured in thread length.
  • a moiré detection (likewise not shown) can also be provided per spinning station, which controls the magnet 4 for the fiber feeding when a certain tolerance limit is exceeded.
  • An individual drive motor 41 can also be provided for each spinning element, for example a spinning rotor.
  • the drive motor is coupled to the thread monitor 40 Assigned switch 42, via which the drive motor 41 can be connected to a frequency transmitter 43 controlling its speed. Further, electrically controlled elements can also be provided.
  • Lines 5, 50, 51, 52, 53 and 54 run along the spinning machine 1, which either serve the normal power supply (lines 5 and 50) or as a control connection (lines 51 to 54) of the individual spinning positions 10, 11, 12 and 13 serve with the maintenance device 2.
  • trailing cables 6 see FIG. 1 or sliding contacts 60 (FIG. 2) are provided, via which the maintenance device 2 is continuously connected to the collecting lines 51, 52, 53 and 54.
  • the individual spinning positions 10, 11, 12 and 13 can each be connected to the collecting lines 51, 52, 53 and 54 via the contacts 550, 551, 552 and 553 of a switching device 55, for example a relay.
  • a switching device 55 is in series with a switch 56, when the switching device 55 closes its contacts 550, 551, 552 and 553 and thus the At the same time, the switching device 70 is now switched over in the maintenance device 2, so that the signals now sensed from the spinning station are fed to the control devices 72, 73.
  • control magnet 4 has been addressed by closing the thread monitor 40.
  • the control magnet 4 thus interrupts the fiber feed to the spinning element.
  • the drive motor 41 of the spinning element is stopped via the switch 42 coupled to the thread monitor 40.
  • the frequency predetermined for the drive motor 41 is signaled via the contact 551 and the bus 52 of the control device 73.
  • the maintenance device 2 can synchronously control the run-up of the spinning element to its operating speed, possibly with a temporary activation of a lower tensioning speed, and the switching on of the fiber feed.
  • the control device 73 switches on the programmer 76, which is designed as a frequency transmitter, and which specifies the required frequency corresponding to the desired speed via the bus 52 to the drive motor 41.
  • the fiber feed is controlled by the control device 72 and the programmer 74 supplying the control magnet 4 with a voltage potential of zero for the time during which it is intended to prevent the fiber feed, while switching on the fiber feed by connecting a voltage potential in height from its operating voltage (programmer 75), despite the closed thread monitor 40, the control magnet 4 does not carry any current, since this is supplied by the maintenance device 2.
  • the magnet 560 drops under the influence of the control device 7.
  • the switch 56 is released and the spinning station 10, 11, 12 and 14 works again independently.
  • the spinning station Before the electrical separation of the spinning station 10, 11, 12 and 13 from the maintenance device 2, of course, the spinning station can be checked by the control device 7 in order to determine whether the thread break repair or other correction has been successful, so that the correction can be repeated if necessary can.
  • the switch 56 is either actuated again from the control device 7 or kept pressed during the entire piecing process (see FIG. 2). After the piecing process has been completed, the switch 56 asks whether the thread monitor 40 is in its closed operating state, i.e. whether the thread break could be repaired or not. When the thread monitor 40 registers the normal thread tension, the maintenance device 2 continues; If this thread tension is missing, the maintenance device 2 repeats the piecing process.
  • the piecing is carried out in a conventional manner and, if desired, also includes cleaning the spinning element, special preparation of the thread end, etc.
  • FIG. 3 shows a full bobbin 80, which is supported on a winding roller 8 and is driven by this.
  • a sensing unit 81 is arranged in relation to the spool 80 diametrically opposite the winding roller 8.
  • This scanning unit 81 contains a light barrier (not shown) and a photocell (not shown), which registers the light beam reflected by the coil 80 and emits a switching pulse depending on the intensity, which depends on the coil size.
  • the probe unit 81 can be adjusted radially to the coil 80 in the embodiment shown (see arrow 85).
  • FIG. 4 shows another embodiment of the coil scanning, according to which the scanning device 81 consists of a light source 82 and a photocell 83 which is spatially separated therefrom.
  • the light barrier 84 extending from this light barrier 81 to the photocell 83 is arranged transversely to the stroke direction (see arrow 85) of the coil 80.
  • this light barrier 84 is adjustable in the direction of arrow 85 in order to be able to change the bobbin with different bobbin diameters.
  • the bobbin 80 is assigned a bobbin support element 86 which can separate the bobbin 80 from its winding roller 8 and thus stop it.
  • a further key unit 88 is provided, which can also be connected to the maintenance device 2 via the switch 57.
  • This key unit 88 is arranged in such a way that it detects whether or not an empty tube 87 is in the ready position at the relevant spinning station 10, 11, 12 or 13 and whether a spool change can thus be carried out here or not.
  • the maintenance device 2 stops, produces a thread break, then corrects it and then carries out a bobbin change. If the scanning unit 87 is not addressed, but only the scanning unit 81, the maintenance device 2 drives past this spinning station 10, 11, 12 or 13.
  • the actuating device which according to the described embodiment has two switching cams 20 and 21 which can be brought into effect alternately and an armature 561, can be designed in various ways. If only a single direction of rotation 3 or 30 of the maintenance device 2 is provided around the spinning machine 1 because the maintenance device 2 orbits the spinning machine 1, then a single switching cam 20 or 21 is sufficient. If, on the other hand, the maintenance device 2 is commuting on one side of the spinning machine 1 moves up and down, it may be sufficient to provide a single correspondingly long switching cam, which is already before reaching one Spinning station 10, 11, 12 and 13, respectively, actuates switch 56 after they have left, the delivery of control commands to the spinning station being controlled as a function of centering device 22.
  • two switchable switching cams 20 and 21 can also be provided, the switching of which takes place when the direction of rotation of the maintenance device 2 is reversed.
  • the signals can be stored in a memory in the maintenance device 2 until they are called up again when actuated by the centering device 22 and initiate the delivery of control signals.
  • the switching cams 20 and 21 can also have such a length that they still work together with the switch 56 in the working position.
  • the switching of the switching cams 20 and 21 can be done when the direction of rotation of the drive motor 710 is reversed or by a stop (not shown) at the end of the machine, which brings the switching cams arranged in the manner of a rocker on a common lever into their other switching position, where they can be switched by a locking device, etc. be secured.
  • the centering device 22 can itself also be designed as an actuating device and thus make the magnet 560 ′ with its armature 561 superfluous.
  • the switch 56 does not necessarily have to be operated mechanically, but can be used as an induction switch, light barrier, etc. be formed, to which a corresponding switching flag (possibly as a reflector for the light barrier) on the maintenance device 2 is assigned as an actuating device. If necessary, this can also be adjustable in length if this should be advantageous for some reason.
  • the centering device 22 can also be non-contact, e.g. with the help of a light barrier, work or be combined with one, so that, for example, a light barrier performs the pre-adjustment and a mechanical device carries out the fine adjustment.
  • the collecting lines 51, 52, 53 and 54 serve to transmit signals from the spinning station 10, 11, 12 and 13 to the evaluation devices (control devices 72, 73) of the maintenance device 2 and also from their control devices (programmer 74,. 75, 76 ) to the spinning station.

  • control devices control devices
  • the embodiment selected in the exemplary embodiment shown is particularly advantageous.
  • connection of the S ammeltechnischen 51, 52, 53 and 54 with the elements can be controlled (control magnet 4, drive motor 41) between this element and the associated switching element (thread monitor 40, switch 42). If necessary, suitable measures can be taken to limit the current of the switching elements (40, 42) as overload. protection should be provided.
  • the frequency generator 43 for the drive motors 41 of all spinning stations 10, 11, 12, 13 can also be provided centrally in the spinning machine 1, the switch 42 being designed as a changeover switch which connects the drive motor 41 either with the frequency generator 43 or with the collecting line 50 connects.
  • the invention also makes it possible to switch the elements 4, 41 to be controlled on and off several times by the maintenance device 2, if desired.
  • the invention is not limited to the embodiment described, but also includes solutions in which individual features are replaced by equivalents, interchanged or combined with one another.
