Definitions

  • the invention relates to a rotary gate of a sample warping machine with a support rotatably mounted about a rotation axis, on which a plurality of coil seats are arranged.
  • the invention relates to a sample warping machine with a warping drum, thread guides, which are rotatable about the axis of the warping drum, and a rotary gate.
  • pattern chains or short chains pattern warping machines are often used in which a warping drum with a relatively large circumference, for example, about 7 m when winding threads is held against rotation.
  • several conveyor belts are provided, which are parallel to the Axis of the warping drum.
  • the thread guides rotate about the axis of the warping drum.
  • Each thread guide lays a thread on the conveyor belts, the thread being pulled out of a gate.
  • a so-called rotary gate is required, which rotates synchronously with the yarn guides. If you do not want to store individual threads on the circumference of the warping drum, you can take them out of the warping process and, for example, wrap around a soul, which is arranged in the axis of the warping drum.
  • the filaments withdrawn from the rotary creel by the spools are consumed with different lengths. This can cause a spool to drain before the chain is finished. Accordingly, a monitoring person is usually required, which continuously checks whether there is enough thread stock remaining on the bobbins. If a spool has run out, then the sample warping machine must be stopped. The corresponding coil must be replaced. It can knot the end of the thread of the expired coil with the beginning of the thread of the new coil, so to speak to ensure continuous operation.
  • the invention has for its object to minimize the risk of disturbances in the operation of a sample warping machine.
  • This object is achieved with a rotary gate of the type mentioned above in that a sensor arrangement is provided, with which a degree of filling arranged in the coil receiving coils can be determined.
  • the sensor arrangement preferably has a sensor for each coil receptacle. It is therefore possible at the same time to determine the corresponding thread supply for all bobbin holders.
  • the sensor in each coil receptacle can continuously determine the degree of filling of the coil, which is arranged in the corresponding coil receptacle.
  • the sensor arrangement has a common sensor for a group of coils. This sensor then determines the degree of filling of the coils in succession. Thus, the information about the degree of filling is not available at the same time. However, it is available after a complete rotation of the rotary gate, which is usually sufficient because in one revolution of the rotary gate only one thread length is subtracted, which corresponds to the circumference of the warping drum. In both cases, i. with a common sensor for several coils or a sensor for each coil, one can then, when the thread supply to the spool is running low, interrupt production and replace the empty spool. Under certain circumstances, it may also be favorable if the sensor arrangement generates a warning signal for a certain time before the corresponding coil is idling, so that an operator can summon a spare spool in good time and keep it in readiness.
  • the senor is arranged on a machine frame on which the carrier is rotatably mounted.
  • the machine frame is stationary because it must serve as the basis for the rotation of the carrier. Accordingly, you can arrange a sensor without much effort on the machine frame, in such a way that the coil recordings pass each time the wearer on the sensor. The sensor can then sequentially determine the degree of filling of each coil.
  • the coil receptacles are arranged in at least two groups along the axis of rotation of the carrier one behind the other, wherein the coil receptacles of one group are offset from the coil receptacles of another group by a predetermined first angle to each other, and the sensors are arranged one behind the other on a line parallel to the axis of rotation or at a second angle, which is smaller than the first angle, offset from one another.
  • Such a design has an advantage in the transmission of the filling levels of the coils determined by the sensors to a further processing device.
  • the sensors do not determine the degree of filling of coils of different groups at the same time, but with a small time interval. This facilitates further processing.
  • the sensor arrangement preferably determines a coil diameter.
  • the bobbin diameter can be determined at a point of the axial length of the bobbin. Thus, only the information about the coil diameter at a point of its axial length is available. However, this information is usually sufficient to be able to reliably determine the degree of filling of the respective coil. This is especially true when the coils are wound with a cross winding.
  • the sensor arrangement has non-contact sensors, which are designed in particular as a laser sensor, ultrasonic sensor and / or infrared sensor.
  • non-contact sensors are designed in particular as a laser sensor, ultrasonic sensor and / or infrared sensor.
  • With a non-contact measurement is a burden of wound on the coils threads kept small.
  • a sensor is provided for a plurality of coil arrangements, one avoids a mechanical loading of the coils with each passage past a sensor.
  • the sensor arrangement has at least one sensor with a mechanical sensor.
  • a sensor may be formed, for example, as a follower roller.
  • a mechanical sensor is particularly suitable if the sensor is arranged stationary relative to the coil arrangement.
  • the sensor arrangement is connected to a machine control of a sample warping machine, which stops the sample warping machine when at least one coil has fallen below a filling level setpoint.
  • the sensor assembly is able to determine with sufficient reliability whether a coil threatens to run empty or whether it still has enough thread supply to continue the warping process trouble-free can. If it turns out that the filling level is too low, then the sample warping machine is automatically stopped. The operator is thus at the same time an indication that a coil must be replaced. You can then replace the coil just at the right time, so that not too much thread material remains on the bobbin, but the coil does not run empty and produces a "wild thread breakage".
  • the machine controller is connected to a pattern controller, which is dependent on output a level setpoint from a pattern to be generated.
  • the level setpoint can therefore vary. This makes it possible to ensure that you can still use the thread supply on the bobbin, the full length of the pattern chain can be arched and avoids a node in the pattern length.
  • the pattern controller "knows" how much thread it needs to make a particular pattern. Accordingly, one can easily create a knot-free or knot-poor pattern chain.
  • the object is achieved in a sample warping machine of the type mentioned above in that it has such a rotary gate.
  • the sample warping machine has a placement machine which is connected to the sensor arrangement.
  • the placement machine is capable of making a bobbin change and connecting the beginning of the thread of the new bobbin to the end of the thread of the idle bobbin.
  • this only applies as long as the end of the thread of the idle coil is still available. This is the case when the empty coil is still wound with a residual thread.
  • the placement machine can cut through this residual thread to produce a thread end that can be connected to the thread start of the new coil.
  • a sample warping machine 1 has a warping drum 2, which has at its periphery a plurality of conveyor belts 3, which run parallel to the axis 4 of the warping drum 2.
  • the warping drum 2 is rotatably mounted. However, it is blocked when winding threads against rotation.
  • a front side of the warping drum 2 opposite a rotary gate 5 is arranged. From the rotary gate 5 threads 6 are deducted, which can be stored with the help of yarn guides 7 on the conveyor belts 3.
  • the yarn guides 7 can be pivoted in the axial direction of the warping drum 2 via the conveyor belts 3. In this case, the threads 6 are deposited on the conveyor belts 3.
  • the yarn guides 7 can also be pivoted so that they deposit the threads 6 on a core 8, which runs approximately in the axis 4 of the warping drum 2.
  • the rotary gate has at least one carrier 9, 15, on which a plurality of coil receptacles 10 are arranged.
  • a coil 11, 14 are arranged in each coil receptacle 10. From each coil 11, 14, a thread 6 is then withdrawn and fed to a corresponding yarn guide 7.
  • FIGS. 2 and 3 illustrated rotary gates 5 is provided for receiving a total of 24 coils 11.
  • These coils are arranged in two groups 12, 13, which are offset from each other along the axis 4 of the warping drum 2.
  • the coils 11, 14 of the two groups 12, 13 are also offset from each other by a first angle, for example by 15 °.
  • the coils 14 of the second group 13 are also attached to a carrier 15.
  • the two carriers 9, 15 can be rotated by a rotary drive 16 in rotation, wherein the rotary drive 16 and the yarn guide 7 rotatably drives.
  • a sensor 17 is provided for each coil receiving 10, which determines a degree of filling of the arranged in the coil receiving 10 coil 11.
  • a sensor 18 is provided on the carrier 15 for each coil 14, which determines the degree of filling in a corresponding manner for each coil 14. The determination of the degree of filling can be done easily generate that the sensors 17, 18 determine the diameter of the respective coils 11, 14. This is sufficient in particular for cross-wound coils in order to be able to obtain a reliable statement about the degree of filling. Alternatively, for example, the mass of the coils 11, 14 are determined.
  • the sensors 17, 18 may be provided with a mechanical sensor, for example, a running on the circumference of the coil 11, 14 roller, which is connected via an arm with a transmitter.
  • the sensors 17, 18 can also work without contact. In this case, they can be designed as a laser sensor, as an ultrasonic sensor and / or as an infrared sensor. If one assigns a separate sensor 17, 18 to each coil receptacle 10, then the information about the degree of filling of each coil is, so to speak, permanently available.
  • sensors 19, 20 instead of the sensors 17, 18, which are associated with each coil receptacle 10, which are arranged on a machine frame 21, in such a way that upon rotation of the supports 9, 15, the coils 11, 14 move past the sensors 19, 20.
  • the sensors 19, 20 may be provided with a mechanical sensor.
  • the sensors 19, 20 are designed as non-contact sensors.
  • the two sensors 19, 20 must never perform a measurement at the same time. If the one sensor 19 determines the degree of filling of a coil 11, then there is a gap between two coils 14 above the other sensor 20. This facilitates the further processing of the signals from the sensors 19, 20. Of course, it is also possible, the two sensors 19th , 20 to offset a small angle relative to each other, as long as it is ensured that the two sensors 19, 20 need not simultaneously determine the degree of filling of a coil 11, 14.
  • the sensors 17, 18; 19, 20 connected to a machine control of the sample warping machine 1.
  • This machine control stops the sample warping machine 1 when at least one coil 11, 14 has fallen below a filling level setpoint.
  • This level setpoint can then, if by means of the sensors 17, 18; 19, 20 determines the diameter of the coils 11, 14, be a fixed diameter value, which results from the empty bobbin diameter and a small order height. In this case, it can be ensured that a spool 11, 14 does not idle, but the pattern warping machine 1 is stopped before the spool 11, 14 idles. In this case, the coil 11, 14 can be replaced. This can be done as in Fig. 1 is shown schematically, a placement machine 22 may be provided.
  • the pick and place machine 22 fetches a full reel from a reel magazine 23, removes an empty reel from the reel 5 and replaces it with the full reel picked up. In this case, the insertion machine 22 cuts through the thread from the empty bobbin between the corresponding thread guide 7 and the empty bobbin and knots it with the beginning of the new or full bobbin.
  • the machine controller is connected to a pattern controller which outputs a level setpoint in dependence on a pattern to be generated.
  • a pattern controller which outputs a level setpoint in dependence on a pattern to be generated.
