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 to the electrically controlled ones being made at the desired spinning point by means of a plug Elements is produced (DE-B-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 fallen due to a thread break, whereupon the maintenance device stops at the relevant spinning position (DE-A-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 as a function of the position of the maintenance device, and the various, electrically controlled elements of 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 that the collecting lines can be connected alternately either to control devices arranged in the maintenance device or to programmers. 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 an actuating device which leads it 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 thereof and reliable maintenance of the relevant spinning station which is linked to the desired spinning station is ensured, even if the maintenance device is normally , ie in the event of non-existent errors or a break in the journey along the individual spinning positions of the spinning machine. 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 a further actuating device for the switching devices, which takes effect in the working position of the maintenance device.
  • an individual drive motor is used as the element to be controlled for the spinning element, it can be provided according to a further feature of the invention that the programmer can be connected to the individual drive motor and is connected via the switching device to the connecting line between the drive motor and a further switching device which the drive motor can be connected to another programmer. In this way, by appropriately controlling the switching devices, it is possible to control the individual drive motor either from one programmer or the other.
  • the further switching device is preferably coupled to the thread monitor.
  • the two switching devices can also be combined to form a changeover switch, which alternately connects the drive motor to one of the two programmer.
  • the two program transmitters advantageously each comprise a frequency transmitter.
  • the further programmer, with which the individual drive motor can be connected is expediently not provided separately for each spinning station, but rather only once in the spinning machine centrally for a larger number of spinning stations or for all spinning stations together.
  • this electromagnet which is used as an element to be controlled, also has a thread monitor known per se the supply line can be connected, the control device being linked via the switching device to the connection line between the electromagnet and the thread monitor.
  • the control device advantageously has two programmers which can be switched on and off alternately.
  • the maintenance device In order to safely separate the driving of the maintenance device and the control intervention of the maintenance device in the spinning station, the maintenance device preferably has a switchover device for switching over between a control device for a travel drive motor of the maintenance device and the control devices for controlling the controllable elements.
  • the maintenance device contains a bobbin changing device
  • a sensing device assigned to the bobbin which can be connected in terms of control with the bobbin changing device provided in the maintenance device, and a bobbin support element is assigned to the coil is, which stops the bobbin by control by the thread monitor and releases the bobbin by control by the maintenance device.
  • the pushbutton device contains a light barrier.
  • the probe device is expediently adjustable for adaptation to different coil diameters.
  • a scanning device is provided per scanning unit for scanning empty tubes which are in a standby position.
  • the subject of the invention only requires a single signal transmission point between the machine and the maintenance device and the maintenance device and machine, which, moreover, is never interrupted.
  • the required connection of this maintenance device takes place, controlled from this, by actuating a switching element provided at the spinning position, which can be effected in a simple manner by touching 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 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 assigned a switch 42 coupled to the thread monitor 40, via which switch 42 the drive motor 41 can be connected to a frequency transmitter 43 controlling its speed.
  • electrically controlled elements can also be provided.
  • manifolds 5, 50, 51, 52, 53 and 54 which either serve the normal power supply (manifolds 5 and 50) or as a control connection (manifolds 51 to 54) of the individual spinning stations 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 stations 10, 11, 12 and 13 can each be connected via contacts 550, 551, 552 and 553 to a switching device 55, e.g. of a relay to which busbars 51, 52, 53 and 54 are connected.
  • Each 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 establishes the connection between the corresponding spinning station 10, 11, 12 and 13 and the maintenance device 2.
  • a first switching cam 20 is provided on the maintenance device 2, which closes the switch 56 when it approaches a spinning station 10, 11, 12 or 13 in the direction of the arrow 3.
  • the switching cam 20 is pivoted into its out-of-work position and a switching cam 21 is brought into its working position. Further details will be explained later.
  • the two switching cams 20 and 21 are located on opposite sides of the maintenance device 2 and can be brought alternately into and out of the working position in such a way that the leading switching cams 20 and 21 are always effective.
  • the maintenance device 2 has a control device 7 which, among other things, also has a switching device 70.
  • This switching device 70 connects the spinning station 10, 11, 12 and 13 that is switched on either to a control device 71 for the traction drive motor 710 of the maintenance device 2 or else to control devices 72 and 73 for evaluating the spinning station 10, 11, 12 and 13 that is switched on queried signals and for connection to programmer 74, 75 or 76 for subsequent control of this spinning station.
  • the program transmitters 74, 75 and 76 are connected to the control devices 72 and 73, an amplifier 77 or 78 being able to be interposed if necessary.
  • the maintenance device 2 also has a centering device 22 which, when it reaches its final working position with respect to a spinning station 10, 11, 12 or 13, actuates a switch 220, which in turn actuates a magnet 560, the armature 561 of which actuates the switch 56 and Switching device 70 is used.
  • the control device 7 determines by evaluating the signals of the spinning station 10 that it is working properly, the maintenance device 2 runs without a stopover, i.e. without interruption of the journey, to the next spinning station 11. If, however, this evaluation by the control device 7 shows that any of the monitored elements emits a false signal, the control device 71 for the drive motor 710 of the maintenance device 2 is switched on via the switchover device 70, which brakes of the maintenance device 2 until the switch 220 is closed by the centering device 22 when the exact working position with respect to the spinning position 10, 11, 12 or 13 is reached.
  • This switch 220 has the effect that the switch 56, which had meanwhile been released again by the maintenance device 2 which has been moved on, is actuated again by the armature 561 of a magnet 560 which has now been addressed and causes the switching device 55 to be excited.
  • 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 550 and the bus 51 of the control device 73.
  • the maintenance device 2 can synchronously give the run-up of the spinning element to its operating speed if necessary, temporarily switch on a lower tightening speed and control the switching on of the fiber feed.
  • the control device 73 switches on the programmer 76, which is designed as a frequency generator, and which specifies the required frequency corresponding to the desired speed via the bus 51 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 zero voltage potential for the time during which it is intended to prevent the fiber feed, while switching on the fiber feed by connecting a voltage potential at a high level 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 13 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 probe unit 81 is arranged.
  • This key 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 source 82 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 has a bobbin support element 86 which can separate the bobbin 80 from its winding roller 8 and thus stop it.
  • the signals of the push button device 81 are also routed via the switch 56.
  • a further key unit 88 is provided, which can also be connected to the maintenance device 2 via the switch 57.
  • This scanning 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. If the two pushbuttons 81 and 87 are addressed, 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 maintenance device 2 stops briefly at the relevant spinning station 10, 11, 12 or 13, in order to generate a thread break by actuating the control magnet 4 and to stop the bobbin 80 as a result of the resulting actuation of the bobbin support element 86. If necessary, the actuation of the control magnet 4 can even take place without interrupting the travel of the maintenance device 2.
  • the actuating device which according to the embodiment described 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, before reaching a spinning station 10, 11, 12 or 13, until it has left the switch 56, the issue of control commands to the spinning station in Dependence on the centering device 22 is controlled.
  • 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 cam 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 locked by a locking device, etc be secured.
  • the centering device 22 can also itself 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 actuated mechanically, but can be designed as an induction switch, light barrier, etc., to which a corresponding switching flag (possibly as a reflector for the light barrier) on the maintenance device 2 is assigned as the 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 72, 73 control devices
  • control devices 72, 73 control devices
  • control devices 74, 75, 76 control devices
  • the embodiment selected in the exemplary embodiment shown is particularly advantageous.
  • connection of the collecting lines 51, 52, 53 and 54 with the elements to be controlled takes place in each case between this element and the associated switching element (thread monitor 40, switch 42).
