Definitions

  • the present invention relates to a method and an apparatus for producing and withdrawing a web-shaped product in the form of a fabric web.
  • the displacement path is not adjustable and, due to the structure, it cannot be very long. It is therefore difficult to adapt to changed product properties or to changed processes.
  • the guide bolts are only clamped at their ends in the device frame, so that the guide bolts can bend with high tensile forces and long displacement distances.
  • the US 3,556,888 describes a procedure similar to that US 2,990,091 .
  • a device is used for pulling, in which several hydraulically driven Terminal segments are distributed across the width of the product.
  • the terminal supports are guided and driven on the underside with respect to the device frame.
  • a continuously running drive chain is used for the feed in the pull-off direction, to which the clamp carriers are connected or disconnected via a pawl.
  • the force application point of the drive chain and the guideway of the clamp carriers in the device frame are at a large distance from the plane at which the tensile stress is built up in the product to be removed. As a result, there is a risk of deformation and / or tension when the trigger tension is high.
  • a high degree of precision in the alternating movement of the two clamp carriers can hardly be achieved.
  • the US 3,819,073 discloses an apparatus for pulling pipes or cables from a production machine.
  • the terminal carriers are driven by a common drive spindle, which is driven by a single motor.
  • the force application point of the drive spindle on the terminal carriers is below the level in which the tensile stress is applied to the product to be removed.
  • they are connected to the drive spindle in various ways by a gear with an auxiliary motor.
  • a further spindle is provided parallel to the drive spindle, on which a plurality of mechanical stops are attached, which serve to actuate limit switches for the movement movements of the terminal supports.
  • the US 4,478,360 discloses a take-off device for tape-like material with two clamp supports, which are arranged on both longitudinal sides of the tape-like material.
  • the associated clamps alternately grip the edge of the band-like material from one of the two long sides.
  • Such an asymmetrical arrangement is not suitable for precise withdrawal with high tensile stresses.
  • the object of the present invention is to provide a method and a device with which a band-like material in the form of a fabric web can be produced and drawn off, which has a high constant during its production Tension and high precision of the take-off movement in relation to the production machine in the form of a weaving machine is required.
  • the clamps are also controlled in such a way that only auxiliary sections of the fabric web that have already been produced are gripped by the clamps when they are removed. This is to ensure that the main sections of the fabric web are free from damage by gripping with the clamps.
  • the drive means of the clamp carriers are controlled as a function of the predetermined tensile stress.
  • the tensile stress can be measured, for example, with strain gauges at suitable points on the clamps or the clamp carriers.
  • the drive means are designed as drive motors with drive spindles, the drive spindles driving the terminal supports in the withdrawal direction or in the direction of the tension.
  • the torque of the drive motors can be measured via the electrical control of the drive motors and - after appropriate conversion - used for the control of the drive motors depending on the tractive force.
  • the method according to the invention can be used particularly advantageously in the production of certain - usually technical - fabrics with a weaving machine. For such fabrics, it is usually sufficient if it has successive main sections of limited length, with certain fabric properties having to be present in these main sections. Only these main sections of the fabric are used in the packaging or further processing of these fabrics. It is therefore possible to weave auxiliary sections between the main sections, which are produced as waste during assembly.
  • the method according to the invention is particularly advantageous in the production of multilayered fabrics. These fabrics can be very thick - for example in the range 5 mm - 80 mm - but even greater thicknesses are possible. If fibers are used in the weft and / or warp that are very stiff - So are not very flexible, the finished fabric can no longer be wound onto a roll in the traditional way after the weaving process, but must essentially be pulled off the weaving machine in the direction of production - usually horizontally.
  • the proposed sections can then be used to produce the main sections of the web-shaped product, for example as a multi-layer fabric with a defined tensile stress and a defined weft density, while in between auxiliary sections are produced which do not have to have any particular fabric properties, but which only serve to separate the main sections to separate.
  • the defined tensile stress in the area of the main sections can easily assume values of up to 20 KN for multi-layer technical fabrics. Since such fabrics are often used in the field of fiber-reinforced plastics with high demands on the uniformity of the mechanical properties, a constant tension and above all a constant, defined weft density is important, especially during the production of the main cuts of the fabric.
  • the following geometric boundary conditions apply to the method presented here and to the device described below for determining the displacement path of the terminal supports.
  • a displacement path that is as large as the complete length of the piece of fabric to be woven is required for the terminal support.
  • the displacement of the clamp carriers is defined as the distance between the two outermost positions of the clamps or the clamp carriers at the beginning and at the end of the device. So that a transfer from one clamp to another can take place while an auxiliary section of a subsequent piece of fabric is being produced, the distance between the exit of the weaving machine and the start of the displacement path for the clamp of the first clamp carrier must not be greater than the length of a complete piece of fabric.
  • the length of a complete piece of tissue must be within the displacement path while the auxiliary section of a subsequent piece of tissue is being produced. If - based on the previously defined boundary conditions - smaller pieces of tissue than the ones described above are to be produced with the same device, the displacement path as a whole - i.e. the distance between the two outermost positions of the clamps or the clamp carriers at the beginning and end of the device - be extended. This then results in a displacement path of the two clamps or the two clamp carriers which is greater than a complete length of the piece of fabric to be woven, namely twice as long as the length of the smallest piece of fabric to be woven. At the same time, the distance between the output of the weaving machine and the start of the displacement path for the clamp of the first clamp carrier must be reduced to 1/2 of the displacement path defined above.
  • a device for pulling off a fabric web from a production machine designed as a weaving machine with two clamp carriers with clamps for the fabric web is also proposed.
  • the device has a device frame on which guide means for the terminal supports are attached. Furthermore are used as drive motors Drive spindles designed drive means are provided, by means of which the clamp carriers can be driven back and forth in a displacement area parallel to a withdrawal direction of the fabric web.
  • the device is characterized in that each of the two clamp carriers which carry out independently adjustable displacement paths can be driven with a pair of drive spindles each driven by a drive motor, the drive spindles being arranged in such a way that the web center of the fabric web within the device lies in a region between the two drive spindles of the respective terminal carrier and the terminals of the terminal carriers can be opened and closed by means of a terminal control such that one of the two terminals is always closed.
  • the pair of drive spindles designed in this way, a uniform distribution of the tensile stress of the fabric web is achieved on the terminal supports and on the drive spindles.
  • a device in which the drive spindles and the fabric web run in the same plane is also favorable. In this way, the force is applied to the spindles in the shortest possible way without unnecessary deflections and largely avoiding deformation of the spindles.
  • the drive spindles are arranged in a plane that runs parallel to the plane in which the fabric web runs.
  • the aforementioned favorable introduction of force onto the spindles is only guaranteed if the distance from one level to the other level is not too great - for example, less than 3 times the diameter of the drive spindles.
  • a uniform distribution of the tensile stresses or the driving forces of the spindles within the clamp carriers can additionally be achieved in that the drive spindles are arranged symmetrically to the center of the clamp carriers in the direction of the width of the fabric web.
  • a further advantageous embodiment of the device results if the drive spindles extend over the entire length of the displacement area, wherein each pair of drive spindles through which one of the two clamp carriers can be driven is mounted in the other clamp carrier.
  • the setting and control of the displacement movement of the take-off device should be adaptable to the properties of the fabric web with auxiliary sections and main sections of different lengths.
  • the fabric web within the device is not arranged symmetrically across the width, but runs on one side.
  • the web widths can be, for example, 50 cm to 150 cm.
  • each of the drive spindles can be driven with its own drive motor. This means that the displacement paths of each terminal carrier can be set independently of the other terminal carrier.
  • an asymmetrical distribution of the tensile stresses on each of the two terminal supports can be absorbed by an asymmetrical control of the two associated drive motors.
  • the guiding means as guideways which are arranged symmetrically in the direction of the width of the fabric web in relation to the center of the terminal support. It is particularly advantageous if the guideways are supported over their entire length in the device frame.
  • At least one roller is attached to one of the two clamp carriers for pulling off the web-shaped product from this clamp carrier, preferably two rollers are provided.
  • the nip is adjustable.
  • At least one of the two rollers can be driven by a motor. This ensures the automatic further transport of the web-shaped product at the outlet of the device.
  • the device according to the invention can be used in a particularly advantageous manner in connection with a weaving machine. This enables the method described above to be carried out, for example, in the production of multilayered fabrics.
  • the Figures 1a to 1f show successive method steps of an embodiment of the method according to the invention.
  • the production machine - in the present case a weaving machine 1 - produces successive pieces 2.1, 2.2 of a multi-layer fabric.
  • Each of the woven pieces 2.1, 2.2 consists of an auxiliary section 3 and a main section 4.
  • the main section 4 is the basis for the end product to be produced.
  • the auxiliary sections 3 are generally much shorter than the main sections 4; they only serve for the separation and handling of the main sections 4.
  • one for the two sections 3, 4 producing fabric piece 2.1 or 2.2 etc. different weave patterns used.
  • Fig. 1a shows that the weaving machine 1 has already produced a piece of fabric 2.1 with a first auxiliary section 3.1 and a first main section 4.1 and that a second auxiliary section 3.2 is currently being produced, which leaves the weaving machine 1 at the exit 5.
  • the exit 5 is the so-called binding point or edge of the fabric in the weaving machine 1.
  • the auxiliary section 3.1 which has already been produced is captured in a device 6 for pulling off the fabric web 2 from a clamp 10.1 and thereby connected to a first clamp carrier 7.1.
  • the device 6 for pulling off has two clamp carriers 7.1, 7.2 with clamps 10.1, 10.2 for the fabric web 2.
  • drive means are provided on the device 6, by means of which the clamp carriers 7.1, 7.2 can be driven back and forth parallel to a withdrawal direction of the fabric web 2.
  • a tension in the pull-off direction of the fabric web 2 is built up in the fabric piece 2.1 via the drive means of this clamp carrier 7.1.
  • This tension is on the loom side over the warp threads to the warp thread supply - for example a warp beam or a creel.
  • the withdrawal of the warp threads from this warp thread supply is controlled by suitable drive or braking means.
  • a measuring device with which the tension in the warp threads - that is the warp tension or the fabric tension - can be measured.
  • the measuring device for measuring can of course also be attached in the area between the terminal supports 7.1, 7.2 of the device 6 for drawing off and the weaving machine 1.
  • the measured tension is passed on to the control devices for the drive or braking devices in the weaving machine 1 and possibly also to the control devices for the drive means of the terminal supports 7.
  • Figure 1b shows that in the further course of the embodiment of the method shown here a second main section 4.2 has already been produced.
  • the first terminal support 7.1 was moved in the pull-off direction.
  • the tension in the fabric web 2 was maintained at a constant level by appropriate control of the drive or braking means.
  • the clamp 10.2 of the second clamp carrier 7.2 detects the first auxiliary section 3.1 of the fabric piece 2.1 and connects it to the second clamp carrier 7.2.
  • a tension is then built up in the tissue piece 2.1 via the drive means of the second clamp carrier 7.2, and then the clamp 10.1 of the first clamp carrier 7.1 is opened.
  • the first clamp carrier 7.1 While the auxiliary section 3.3 is being produced by the weaving machine 1, the first clamp carrier 7.1 is pushed back to its starting point at the entrance of the device 6 for pulling off. During the backward movement, the clamp carriers 7 have a significantly higher displacement speed than in the forward operation. Possible displacement speeds are, for example, 200 mm per minute in the forward mode (ie production speed of the weaving machine) and 3000 mm per minute in the reverse mode. Depending on the type of fabric, other speeds of displacement may of course also be required.
  • the drive means of the terminal supports 7 are to be designed accordingly.
  • FIG Figure 1a-1f The different speeds of the clamp carriers 7 in the different process stages are shown in FIG Figure 1a-1f represented by diagonally running arrows or double arrows.
  • Figure 1e shows that now at the end of the device 6 facing away from the weaving machine 1, the fabric web 2 is taken over by an operator or by a further transport device - this is symbolically represented by the arrow in the take-off direction.
  • the terminal 10.1 of the first terminal carrier 7.1 has meanwhile been closed on the auxiliary section 3.3, and the first terminal carrier 7.1 again has the entire tension between Weaving machine 1 and device 6 taken off.
  • the terminal 10.2 of the second terminal carrier 7.2 can be opened.
  • a further step - see Figure 1f -
  • the second terminal support 7.2 is now pushed back into its starting position. During this time, the weaving machine 1 produces a further main section 4.4.
  • the first clamp carrier 7.1 with the clamped auxiliary section 3.3 is displaced in the pull-off direction.
  • the weaving machine 1 then begins to produce the auxiliary section 3.5.
  • the clamp 10.2 of the second clamp support 7.2 closes on the auxiliary section 3.3 and takes over the full tensile stress in the fabric web 2.
  • the clamp 10.1 opens on the first clamp support 7.1, and this is pushed back to its starting position at an increased displacement speed, where it then moves the auxiliary section 3.4 detected. This completes a complete process cycle.
  • the two terminal supports 7.1, 7.2 again have the positions as in Figure 1a shown. The process continues accordingly from then on.
  • Another advantage of the embodiment of the method according to the invention described here is that the clamps 10.1, 10.2 of the clamp carriers 7.1, 7.2 never grasp the fabric web 2 at the main sections 4 of the fabric pieces 2.1, 2.2, but always only at the auxiliary sections 3. Damage to the Main sections 4 through the terminals 10 are thereby completely excluded. This is particularly useful, for example, in the production of multi-layer fabrics for use in fiber composite components. The fibers of these fabrics are often very sensitive on their surface. Damage to the fibers or to the individual Filaments of a fiber cause problems in the following processing processes.
  • the Figures 2-4 show an embodiment of a device 6 according to the invention for pulling a fabric web.
  • the structure is shown together with a weaving machine 1.
  • the entire arrangement is able to carry out the inventive method described above.
  • the device 6 contains two clamp carriers 7.1 and 7.2 with clamps 10.1, 10.2 for the fabric web 2.
  • There is a device frame 12 by means of which the device 6 is supported on the floor.
  • On the device frame 12 there are guideways 13 for the clamp carriers 7, which in the present example are supported on the device frame 12 over the entire length of the possible displacement path 8 of the clamp carriers 7.
  • These guideways 13 can be designed as profiled slideways or as rolling element guides - so-called ball guides. This ensures precise guidance of the terminal supports 7 without major deformations of the guideways 13.
  • the guideways 13 are arranged symmetrically to the center of the clamp carriers 7 in the direction of the width of the fabric web 2. ( Figure 3 ) to evenly distribute the forces with which the clamp supports 7 are supported in the device 6.
  • the device 6 also contains two pairs of drive spindles 14.1, 14.2, by means of which the clamp carriers 7.1, 7.2 are driven parallel to the take-off direction of the fabric web 2.
  • a pair of these drive spindles 14.1, 14.2 is assigned to each terminal support 7.1, 7.2.
  • the drive spindles 14 are arranged such that the web center of the fabric web 2 within the device 6 runs in a region between the two drive spindles 14 of the respective clamp carrier 7. As a result, a symmetrical introduction of force from the clamp carriers 7 into the drive spindles 14 is achieved when the clamp carriers 7 are under the tension of the fabric web 2.
  • the drive spindles 14 are arranged in the same plane 15 in which the fabric web 2 runs in the device 6.
  • the drive spindles 14 are arranged symmetrically to the center of the clamp carriers 7 in the direction of the width of the fabric web 2. This also serves for the symmetrical introduction of forces into both drive spindles 14.1 or 14.2 of the respective terminal support 7.1 or 7.2. This applies at least when the fabric web 2 is also drawn through the device 6 symmetrically with respect to its width to the center of the terminal supports 7.1, 7.2.
  • the clamps 10.1, 10.2 of the clamp carriers 7.1, 7.2 are each constructed from several pairs of clamp segments. This is best in Figure 4 to see. These clamping segments are arranged next to one another over the width of the clamping supports 7. Each of these clamp segments can be driven with a clamp actuator 11 independently of the other clamp segments. This means that the pairs of clamp segments assigned to one another each form a clamp 10 which can be opened or closed independently of the other clamps.
  • Pneumatic cylinders are used as terminal actuators 11 in the present example. Of course, other types of actuators 11 - for example hydraulic or electromagnetic actuators 11 - can also be used to actuate the terminals 10.
  • the Figure 4 shows the device 6 for pulling the fabric web 2 in a view from above. It can be seen that the drive spindles 14 extend over the entire length of the displacement region 8. Each pair of drive spindles 14.1, 14.2, through which one of the two clamp carriers 7.1, 7.2 can be driven, is mounted in the other clamp carrier 7.2, 7.1. Where the drive forces from the drive spindles 14 are applied to the respective clamp carrier 7, 7 spindle nuts 16 are provided in the clamp carrier. When the spindle rotates, these spindle nuts transmit 16 tensile or compressive forces in the withdrawal direction to the respective clamp carrier 7.
  • each of the four drive spindles 14 can be driven by its own drive motor 9.
  • the torque of the drive motors 9 can be measured in a known manner, for example via the current consumption of the electronic motor control, and can be used to control the drive motors 9.
  • the position determination of the two terminal carriers 7 within the device 6 takes place, for example, via an inductive displacement measuring system - for example in the area of the guideways 13 - or via incremental encoders within the drive motors 9.
  • the number of pulses or revolutions of the drive motors 9 is used to determine the Spindle pitch determined the current position of the respective terminal support 7.
  • the drive motors 9 for the drive spindles 14 are attached to the end of the device 6 that faces away from the weaving machine 1.
  • Axial bearings of the drive spindles in the device frame are also provided on this side.
  • the tensile stresses in the fabric web 2 therefore generate 14 tensile forces in the drive spindles. Pressure forces can only occur in the drive spindles 14 when the clamp carriers 7 are pushed back against the withdrawal direction. However, these are low, so that there is no risk of inadmissible deformations or even buckling.
  • the present embodiment of the device 6 has two take-off rolls 17, 18 on the second clamp carrier 7.2, which form an adjustable roll gap between them.
  • the upper take-off roller 17 can be brought into different positions perpendicular to the fabric web 2 in order to adjust the nip.
  • a suitable actuator 19 - for example a geared motor with a spindle - ensures this positioning relative to the fabric web 2.
  • the lower take-off roller 18 contains an electric drum motor for the drive, for example inside - however, other types of drive with motors outside the take-off roller 18 are also possible. It is also conceivable to drive the upper take-off roller 17 or both rollers 17, 18. With this pair of rollers 17, 18, the fabric web 2 which has been pulled off can be transported further beyond the second clamp carrier 7.2.
  • the fabric web 2 which has already been pulled off can be pulled off if necessary this pair of rollers 17, 18 are supported while the second clamp carrier 7.2 is on the way back from its end position to the starting position (see. Figures 1e and 1f ).
  • Other method sequences can also be implemented with the device described. For example, it would also be possible to control the process in such a way that during most of the process steps it is not the first clamp carrier that absorbs the complete tensile stress of the fabric web, but the second clamp carrier, the first clamp carrier building up only an auxiliary voltage in these phases, which serves to to prevent sagging of the fabric web.
  • the openly accessible displacement areas of the clamp carriers 7, the roll nip between the take-off rolls and the running drive spindles 14 are secured by light grids, not shown.
  • Light grids are used that reliably indicate an interruption of the light beam or light curtain even when the distance between the transmitter and receiver changes.
