Definitions

  • the invention relates to a method and a device for winding windable substrates according to the preamble of the respective independent patent claim.
  • a certain amount of a substance to be tested is wound onto a so-called sample dye tube.
  • This sleeve together with the wound material is exposed to a dye bath.
  • the sleeve has many openings in its wall, so that the entire wound-up material is penetrated by the circulating dyeing liquid in the dye bath.
  • the substances to be dyed have been wound onto the sample dyeing tube in the laboratory in such a way that first the substance to be wound or the end of the substance is manually pulled off a substrate storage roll and the pulled-off material web is manually threaded, i.e. the end of the fabric is attached to the sample dye tube.
  • the sample dyeing tube is then turned by means of a hand-operated crank and the threaded material is placed on the tube, i.e. wrapped around the sleeve.
  • the fabric is cut off with scissors, for example, and the end of the fabric belonging to the winding is attached to the winding (for example, stapled).
  • the winding for example, stapled
  • the density of the individual layers of the material to be dyed wrapped around the sleeve can vary greatly.
  • the material to be dyed can only be wound onto the tube by manual operation under a widely varying tension, so that the areas of the fabric that are wound under higher tension are very much pulled apart, while the areas that are lower Tensile stress are wound up, are less apart.
  • the color impression after the subsequent dyeing of the fabric can also fluctuate greatly, since those areas which are wound apart on the sleeve to different extents, of course during the subsequent dyeing, also differ to a different extent from the dyeing liquid in the dye bath to be penetrated. It is then hardly possible to make a reliable statement about what the color impression of the dyed fabric will be later under production conditions.
  • DE-A-20 57 492 therefore proposes a drive device with the aid of which it is possible to wind winding webs (also including fabrics) onto a carrier with a desired, uniform tensile stress, even if the web speed during the winding process is changeable.
  • the known mass of substrate fluctuates quite considerably in known winding processes, which makes an assessment of the color impression, as it will be later under production conditions, considerably more difficult.
  • the substrate in known laboratory winding devices, the substrate must also be cut off by hand each time the winding process has ended and the cut end must be attached to the winding. The other end of the fabric must then be re-threaded before a new wrapping process begins before a new wrapping process can begin.
  • a large number of substrates are thus made available (for example in a magazine-like manner), and as a first method step (that is, before any "call”, see below), the desired substrate is first selected or defined from this large number of substrates.
  • a time-consuming manual exchange of the substrate provided, that is to say, for example, a substrate storage roll, is avoided. Rather, the selection of the substrate takes place fully automatically after input of the desired substrate, so that this process variant is distinguished by its efficiency
  • the motor drive for transporting the substrate to the substrate carrier is regulated to a uniform feed rate. This ensures that the effort for controlling the drive of the substrate carrier, which is controlled depending on the feed speed, is kept low, since when the transport drive is regulated to a uniform feed speed, the feed speed is subject to smaller fluctuations and thus also correspondingly smaller changes in the control signals must be generated.
  • the mass per unit area of the substrate to be wound is first determined with a known substrate width and with a known substrate thickness and then the desired mass of substrate to be wound on the substrate carrier is determined. On the basis of the mass determined per unit area of the substrate and the specified desired mass of substrate to be wound, corresponding signals for controlling or regulating the motor drives are then generated. The result of this is that, in the case of substrates of known width, the mass of which is unknown per unit area, the mass per unit area is first determined, which is necessary in order to be able to wind a desired (total) mass of substrate onto the substrate carrier.
  • this determination of the mass per unit area of the substrate is also advantageous for substrates whose mass per unit area is known as the standard value, since there may also be deviations from this standard value with such standard substrates, and with the aid of this embodiment variant a simple " Calibration "is possible.
  • the mass per unit area can advantageously be determined by first determining the weight of the unwound substrate carrier, the diameter of which is known. Subsequently, substrate is wound onto the substrate carrier until a predetermined diameter of the wound substrate carrier is reached. The weight of the wound substrate carrier is then determined. If substrate width and substrate thickness are known, then the mass per unit area of the substrate is determined on the basis of all these values. If the substrate thickness is known, the diameter of the wound substrate carrier can then be determined and monitored in advance for a desired mass of substrate to be wound onto the substrate carrier, so that the winding process is stopped when the predicted diameter of the wound substrate carrier is reached.
  • the desired tensile stress with which the substrate is to be wound onto the substrate carrier and the desired duration of the winding process are determined.
  • signals for controlling or regulating the motor drives are then generated on the basis of these values.
  • the object of the invention is achieved as specified in the features of patent claim 6.
  • a large number of substrate storage rolls are therefore provided, and holding means are provided for each storage roll, which hold the substrate end belonging to the respective storage roll in a defined storage position.
  • a separate, motor-driven pair of pull rollers is provided for each storage roll, between which the substrate is clamped.
  • input means are provided for determining the desired substrate to be wound onto the substrate carrier, the motorized transport drive moving to the pulling rollers of the substrate selected via the input means or to the corresponding substrate storage roller, and the drive to the pulling rollers of the selected one, due to the determination of the desired substrate Coupled substrate.
  • Means are also provided for moving the substrate carrier into a threading position, in which the substrate carrier then engages in the substrate and threads it around the substrate carrier. After the threading, these means for moving the substrate carrier move the substrate carrier from the threading position into a winding position in which the substrate is wound around the substrate carrier. After the substrate has been wound up and cut off, the holding means provided in the respective storage roll hold the end of the substrate not belonging to the winding again in the defined storage position.
  • the device according to the invention thus operates essentially fully automatically and is therefore very particularly efficient.
  • the control for the transport drive regulates the feed rate of the substrate to a uniform feed rate.
  • the effort for controlling the drive of the substrate carrier which is controlled as a function of the feed speed, is kept low, since when the transport drive is regulated to a uniform feed speed, the feed speed is subject to smaller fluctuations and thus also produces correspondingly smaller changes in the control signals Need to become.
  • the holding means for holding the substrate in the defined storage position comprise a holding rail or a holding element which has a holding surface with suction openings facing the substrate carrier moved into the threading position and a negative pressure connection which is connected to a negative pressure source via a valve.
  • the holding element When threading the substrate, the holding element is connected to the negative pressure source in terms of pressure, so that it generates a negative pressure through the suction openings in the holding surface and sucks the substrate against the holding surface.
  • the substrate carrier has on its outer wall around the longitudinal axis several areas in which needles are provided projecting essentially radially outward from its outer wall. These needles engage in the substrate held in the storage position. In the holding surface of the holding element, corresponding grooves are cut out for these needles of the substrate carrier, so that the substrate carrier can be driven (rotated) without hindrance.
  • the valve separates the vacuum source from the holding element in terms of pressure, so that it releases the substrate away from the holding surface for winding.
  • the means for cutting in the direction of transport of the substrate are arranged immediately after the holding element. This arrangement enables the end of the substrate not belonging to the winding to be held in the manner already explained after the substrate has been cut off by the holding element with the aid of the vacuum source, and then the threading of the substrate onto the next substrate carrier likewise in the simple and reliable manner already explained and way can be done automatically.
  • the means which fix the substrate end belonging to the winding to the winding comprise a ring which is provided coaxially to the longitudinal axis of the substrate carrier in the vicinity of the substrate carrier end on the respective substrate carrier. On its inner surface, this ring is provided with a circumferential groove in which the substrate carrier can circulate freely during winding.
  • a pin is provided on the outside of the ring, which is arranged essentially perpendicular to the longitudinal section plane through the substrate carrier and around which operable fixing domes are pivotably mounted between two positions. When the substrate is wound onto the substrate carrier, these are pivoted out into a winding position, in which do not hinder the winding of the substrate onto the substrate carrier.
  • a fixing position on the other hand, they are pivoted essentially in the longitudinal direction of the substrate carrier and at least pierce the outer two layers of the wound substrate and thus fix them together.
  • This embodiment of the device enables simple automatic fixing of the end of the substrate belonging to the winding on the winding. At the same time, the substrate can be threaded and wound up in the manner already explained.
  • actuating members are provided which swivel the fixing mandrels into the winding position before the threading process begins and which pivot the fixing mandrels into the fixing position after the winding process has ended.
  • means are provided for determining the mass per unit area of the substrate, the substrate width and the substrate thickness being known. Furthermore, input means are provided for determining the desired mass of substrate to be wound on the substrate carrier, and computing means are provided which, on the basis of the mass determined per unit area of the substrate and the desired mass to be wound up, correspond to signals for controlling the drive of the substrate carrier or for regulating generate the transport drive and forward to it.
  • This exemplary embodiment permits "calibration" and thus enables a desired mass of substrate to be wound onto a substrate carrier.
  • weighing means for determining the weight of the unwound and the wound substrate carrier are provided for determining the mass per unit area.
  • means are also provided for monitoring the diameter of the wound substrate carrier, which stop the winding process when the diameter of the wound substrate carrier reaches a predetermined diameter. If the diameter of the unwound substrate carrier is known, the computing means then calculate the mass per unit area of the substrate on the basis of these values. Based on the desired mass of substrate to be wound up, they calculate the diameter of the wound substrate carrier in advance and position the means for monitoring the diameter of the wound substrate carrier in such a way that when the predicted diameter is reached they detect it and thus stop the winding process.
  • input means are provided for determining the desired mass of substrate to be wound onto the substrate carrier, for determining the desired tensile stress of the substrate on the substrate carrier and for determining the duration of a winding process.
  • electronic computational means calculate and generate corresponding control signals for the drive motors or their control or regulation on the basis of these values.
  • an impermissible parameter has been entered for a specific substrate (for example a tensile stress that is too high and incompatible with the substrate)
  • the electronic-computer means can recognize this and display it to the user.

  • the textiles are wound on substrate carriers, for example on sample dye tubes.
  • the laboratory dyeing line comprises a storage container 5 for dye powder, which can be placed in solution in a dosing station 6. The wound sample dye tube can then be exposed to the dye mixture in a dye bath 7 and the textiles can be dyed in this way.
  • a basic arrangement which comprises a drive 300 for transporting the textile 2 from the storage roll 3 to a pattern dyeing sleeve 40 and a drive 400 for winding the textile 2 onto the sleeve 40, is shown in FIG. 2.
  • the arrangement shown here further comprises pulling rollers 31 and 32, between which the textile 2 is clamped, and which can be driven by means of the drive 300.

  • a uniform feed rate of the textile 2 to the sleeve 40 is assumed.
  • the computer 41 If the computer 41 knows the thickness of the textile to be wound, it calculates a signal for the control 410 depending on the current feed speed, which then controls the drive 400 for the sleeve in such a way that the textile 2 applies uniform tension to the sleeve 40 is wound up.
  • a control 310 is also provided, which controls the drive 300 for the pull rollers 31 and 32, respectively, in such a way that the textile 2 is transported to the sleeve 40 at a uniform feed rate.

  • the computer 41 Based on the current feed rate of the textile 2, the computer 41 then calculates the current signal for the controller 410, which controls the drive 400 accordingly. In this way it is ensured that the textile 2 is wound around the sleeve 40 with a uniform tension. At the same time, the computer also calculates a signal for the control 310, which controls the drive 300 for the pull rollers 31 and 32 so that the textile 2 is transported to the sleeve 40 at a uniform feed rate, whereby the computational effort is reduced.
  • FIGS. 4 to 12 a possible embodiment of the winding device will be explained with reference to FIGS. 4 to 12.

  • the ring 45 on which the pin 450 is provided, around which the fixing pins 44 are pivotally mounted can no longer rotate with the sleeve 40.
  • the sleeve 40 can then, as already explained with reference to FIGS. 7 and 8, rotate freely in the groove 451 in the inner surface of the ring 45.
  • the fixing mandrels 44 In order to be able to thread the textile 2 and to wind it around the sleeve 40, the fixing mandrels 44 must be pivoted out of the fixing position (upper position in FIG. 9).
  • One possibility of pivoting the fixing domes 44 out of this fixing position into a winding position, in which they do not hinder the threading and winding process is shown in Fig. 9.
  • a guide plate 463 At the bottom of the spar 460, a guide plate 463 is provided, in which an elongated hole 464 is recessed.

  • the piston rod 471 can be moved up and down with the aid of a piston drive 474, which can, for example, function hydraulically or pneumatically and is preferably electrically controllable. If the fixing mandrels have slid into the holding stops 461 (upper dashed position, fixing position), the piston drive 474 moves the piston rod 471 downward. As a result, the spar 460 is also moved downward, the pin 472 being able to slide in the slot 464 of the guide plate 463.
  • the fixing mandrels 44 are pivoted out into a winding position in this way, as is indicated in FIG. 9, the threading and then the winding process can begin. At this point it should be noted that it is not necessary to pivot the fixing mandrels 44 out of the fixing position by 90 °, as is indicated in FIG. 8. It was only a matter of showing that the fixing domes 44 can be swung out of the fixing position at all, to the extent that they do not hinder the threading or winding of the textile 2 onto the sleeve 40. If the sleeve 40 is wound, the piston drive 474 moves the piston rod 471 up again until the fixing mandrels 44 pierce the textile 2 so that it is fixed (FIG. 7).
  • the sleeve is then rotated a little counter to the winding direction of rotation, that is, counter to the direction of the arrow 40b (here clockwise), so that the fixing mandrels 44 can slide out of the openings 462 of the stops 461 again.
  • the textile 2 guided between the pulling rollers 31 and 32 which is held in the storage position (FIG. 4), can be seen again in FIG. 10. Due to the negative pressure generated through the suction openings 421 (FIG. 6), it is sucked into the curved holding surface 420 of the holding element 42 and held there.
  • the sleeve 40 is initially arranged in the winding position, which is indicated by the axis of rotation 406. In this position, the fixing mandrels 44 are pivoted out of the fixing position into the winding position in the manner explained. The sleeve 40 is then moved into the threading position (axis of rotation 407).
  • the sleeve 40 is provided on its outer wall around the sleeve in several areas with needles 403 which protrude radially outward from the outer wall. These needles 403 are indicated in FIG. 10. As can be seen in FIGS. 6, 7 and 8 (and also indicated in FIG. 10), the needles 403 engage in the textile 2 to be threaded, ie they pierce it. In the areas in which the needles 403 pierce the textile 2, 42 grooves 422 are recessed in the holding surface 420 of the holding element. In Fig. 6, in which the sleeve is shown in the threading position, three such grooves 422 are exemplary shown.
  • the vacuum source 431 is separated in terms of pressure from the holding element 42, for example with the aid of the controllable valve 432.
  • the sleeve is, for example, two complete rotations about its axis of rotation 407 in the winding direction (here turned counterclockwise).
  • the needles 403 can be rotated with the sleeve 40 and can engage in the textile 2 without being hindered by the holding element 42 or its holding surface 420.
  • the textile 2 is now sufficiently securely threaded around the sleeve 40 and the sleeve 40 is moved into the winding position (axis of rotation 406, FIG.
  • the actual winding process begins, in which the textile 2 is then wound onto the sleeve 40.
  • the sensor S which is preferably arranged to be adjustable, detects an overall diameter of the sleeve 40 with the wound textile 2, it sends a corresponding signal to the control 410 of the drive 400 (FIG. 3), which ends the winding process by both the drive 400 for the sleeve 40 and the drive 300 for the pull rollers 31 and 32 is switched off.
  • the fixing mandrels 44 are moved into the fixing position in the manner already explained, in which they at least pierce the outer two layers of the textile 2 and thus fix it to the winding.
  • the textile 2 must now be cut off. So that the cut end of the textile 2, which is not fixed to the winding, cannot roll up or move into a position in which it cannot subsequently be automatically wound onto the next sleeve 40 to be wound, the controllable one becomes first according to FIG. 10
  • Valve 432 is actuated so that the vacuum source 431 is pressure-connected again to the holding element 42 via the connection 430 and creates a negative pressure through the openings 421 (FIG.
  • the textile can be cut, for example, as will be explained below with reference to FIGS. 11 and 12.
  • a cut sheet 48 is placed between the textile web held on the holding surface 420 and the textile wound on the sleeve 40, i.e. between the textile web held in the storage position and the winding , swung in.
  • the cutting plate 48 acts like the one blade of a pair of scissors, which is shown in more detail with reference to FIG is explained.
  • the pivoting of the cutting plate is conceivable in many ways, in Fig. 11 this possibility of pivoting is only indicated symbolically by the slot 481 and the shaft 482, around which the cutting plate 48 is pivotally mounted.
  • a further cutting plate 49 which acts like the second blade of a pair of scissors, is moved against the cutting plate 48 and the textile is thus severed. This will be explained in more detail below with reference to FIG. 12.
  • Fig. 12 which shows a section along the line XII-XII of Fig. 11, for the sake of simplicity only the sleeve 40 wound with textile 2 and the two cutting plates 48 and 49, which act like the two blades of a pair of scissors, are shown .
  • the position of the textile 2 lying on the outside of the cutting plate 48 can still be seen.
  • the cutting plate 48 one blade of the "scissors" is held in its position after pivoting in, while the other cutting plate 49 (the other Blade of "scissors”) how the second blade of a pair of scissors is moved. This can be done as shown in FIG.
  • a pin 495 or 496 is connected to the piston rods 493 or 494 in a projecting manner, the pins 495 and 496 reaching through an opening 497 or 498 in the cutting plate 49 and similar to the actuating element for pivoting out the fixing pins 44 (FIG. 9) are secured by adjusting rings 495a and 496a (Fig. 11) against lateral sliding out of the respective openings 497 and 498, respectively.
  • the piston drive 491 first moves the piston rod 493 upwards until the upper edge of the cutting plate 49 reaches approximately the height of the lower edge of the cutting plate 48, that is to say to the height of the other blade of the "scissors".
  • the other piston rod 494 initially remains in the position shown in FIG. 12. Since the pin 495 on the piston rod 493 and the cutting plate 49 are not movable in the longitudinal direction relative to one another, because the opening 497 through which the pin 495 projects is designed only as a through hole, the cutting plate 49 becomes relative to the pin 496 on the piston rod slightly moved, as shown in Fig. 12 to the right.
  • the other cutting plate 48 can now be swung out again, the wound sleeve 40 can be moved away and, for example, fed to a sample dye bath. A new unwound sleeve can then be moved up and the textile 2 can be threaded around this new sleeve from the storage position in the manner explained above.
  • the actual mass per unit area of the textile to be wound up has to be determined once for a storage roll so that subsequently many winding processes can take place and a uniform mass of substrate can always be wound up.
  • the width and the thickness of the textiles on the storage rolls are known.
  • the calibration can now be carried out as follows: First, the empty weight of a sleeve to be wound is determined, for example, by weighing it using a balance. The diameter of the unwound sleeve is also known. The textile is then threaded in the manner previously explained and wound onto the sleeve. At this point, reference should again be made to FIG. 10. Textile is wound up in the winding position (axis of rotation 406) until the sensor S detects a predetermined overall diameter of the sleeve 40 wound with textile 2. In accordance with this previously determined overall diameter, the adjustable sensor S is arranged in a very specific position.
  • the textile is cut off and the sleeve wound with textile is weighed.
  • the difference between the weight the wound and the unwound sleeve corresponds to the weight of the entire substrate wound on the sleeve.
  • D1 T + [(D0-T) 2nd + (4MT / ⁇ B)] 1/2
  • ⁇ mass per unit area of the textile
  • the input console 41a is also used as the first step to select the desired substrate to be wound from a large number of substrates, whereupon the drives 300 and 400 are moved to the corresponding substrate storage roll 3 and the drive 300 is coupled to the corresponding pull rollers 31 and 32, respectively.
