Definitions

  • the invention relates to a method for producing a card sliver with a carding machine according to the preamble of claim 1 and a carding machine for performing this method.
  • the conventional revolving flat card is provided with a so-called flexible sheet on each side, which can be adjusted in relation to the corresponding side plate in order to adjust the carding gap (between the set of flat bars and the set of reel).
  • the setting can be made manually according to DE-Gbm 9313633.
  • the existing carding distance which has increased due to wear and grinding, must be reset.
  • three to five control elements are usually provided on the flexible sheet on each side of the card.
  • the carding distance is measured with a sheet gauge at various points and set.
  • this work is time-consuming and results in downtimes of up to one day on a single card.
  • the spinning mills want to utilize the operating times of the machines to the fullest possible and therefore try to minimize the downtimes for machine revisions. In many spinning mills, this revision work is therefore only carried out at the last moment, that is, when the quality of the card sliver produced is almost sufficient or even below the tolerance.
  • FIG. 1 schematically shows a revolving flat card 1 known per se, for example card C50 from the applicant.
  • the fiber material is fed into the filling shaft 2 in the form of dissolved and cleaned flakes, taken over as a wadding by a breeze or licker-in 3, transferred to a drum or drum 4 and parallelized by a revolving cover set 5, which rotates via deflection rollers 6 in the opposite direction to the direction of rotation of the drum 4 is driven.
  • Fibers from the nonwoven fabric located on the reel 4 are then removed from a take-off roller 7 and formed into a card sliver 9 in an outlet section 8 consisting of different rollers.
  • This card sliver 9 is then deposited in a cycloidal manner from a sliver holder 10 into a transport can 11.
  • a section of the flexible sheet 12 of such a card is shown, with circumferential ones Traveling covers 13 (only two shown) which are slowly moved in the same direction or in opposite directions to the direction of rotation of the drum 4 by a toothed belt 14 and a drive (not shown here).
  • Adjustment elements 15 are provided on this flexible sheet 12, with which the distance of the revolving cover 13 to the drum surface, the so-called carding distance, can be adjusted.
  • the structural design of such adjusting elements on the flexible bend is known, for example, from the applicant's German utility model DE-U-93 13 633. In this case, however, the adjusting elements 15 are not only manually adjustable, but are automatically adjustable by means of actuators, for example small actuating motors 17.
  • Piezoelectric translators of the designation P-170 to P-173 from Physik Instrumente GmbH & Co. in D-7517 Waldbronn, for example, are suitable for this task.
  • This actuator system is connected to a controller 16 which determines the setting of the flexible sheet 12, and thus the carding distance; for example according to an adjustment characteristic according to FIG. 3.
  • FIG. 3 shows a diagram which shows the change in the carding distance K on the abscissa as a function of the accumulated card sliver production P in tons (kg) on the ordinate for various processed material types.
  • the curve S indicates the target distance, that is to say the carding distance, which would have been given without wearing the drum set (and the revolving cover).
  • the target distance that is to say the carding distance, which would have been given without wearing the drum set (and the revolving cover).
  • the degree of wear depending on the current production for the different provenances of the Fiber material (A or B) is either known or can be determined empirically, so that this data can be entered into the controller 16 (FIG. 2) and the adjusting elements 15 can be adjusted on the basis of this information.
  • the current production of a card is a function of the delivery speed and the belt number.
  • the total production of a card from a given point in time (e.g. from a set change or a set service) is nowadays determined by a programmable control of the machine and displayed on request, which means that such data is usually already available in the machine control.
  • the "zero point" for the calculation of this total production can of course also be used as the zero point for controlling the adjustment of the carding distance.
  • a prerequisite is that the elements to be adjusted are in a predetermined state at the zero point, which must be guaranteed by the operating personnel. Otherwise it becomes necessary to monitor the "starting position" of the elements with a suitable sensor system and to report it to the control, which significantly increases the effort required.
  • the control can be programmed by the machine supplier with the adjustment characteristic, i.e. the characteristic is entered in the control's memory. The user can then call up the appropriate characteristic by entering the material to be processed.
  • the adjustment is preferably not continuous, but intermittent (step by step) depending on the capabilities of the actuators.
  • the actuator system is preferably able to reliably carry out an adjustment which represents only a fraction (for example a maximum of 20%) of the normal carding distance. Such distances today are in the range of 20 to 30 hundredths of a millimeter.
  • the Actuator reliably perform adjustment steps in the range of 1 to 3 hundredths.
  • the system is best suited for the user who processes a given material type over a longer period.
  • the calculation of the "total production" with frequent material changes will prove to be difficult.
  • time can be used as a control parameter instead of production.
  • the benefit means the effective production time in a given time period.
  • FIG. 4 shows a modification of FIG. 1 of DE-Gbm-93 13 633 in order to be able to carry out the motor adjustment according to this invention.
  • This version also corresponds in part to the actuator system according to FIG. 13 of our Swiss patent application No. 1681/93 (EP 94 810 309.8)
  • FIG. 4 shows an adjusting device 20 on a card in partial cross-section.
  • a flat bar 23 lies with its head piece 24 on a bearing, here a slide or flex bend 25, which is held in a support element 26 with a U-shaped profile with almost no play.
  • the U-shaped profile is provided with a precisely fitting gap in the area of the sliding or flex bend 25, so that it is held in the supporting element 26 in an almost clamping manner.
  • Below the slide or flex bend 25, the U-shaped profile of the support element 26 is expanded so that the above-mentioned almost clamping effect - that is, the precisely fitting guidance - is only necessary in the area of the slide or flex bend 25.
  • the support element 26 is here connected in one piece to a side plate 27, which is only indicated schematically, but it can also be an independent part which is connected to the side plate in a known manner by means of screws or the like.
  • a bore 29 is provided in the base 28 of the support element 26, in which a setting element 31 can move freely in its longitudinal direction.
  • a shoe 30 is provided at the foot of the actuating element 31, which will be discussed in more detail below.
  • a flat and narrow groove can be provided on its shaft, in which an adjusting scale is engraved so that the adjustment of the sliding or flexing bend can be read off directly.
  • the adjusting element 31 and the shoe 30 are arranged outside the drum shield and are therefore always easily accessible.
  • the head 32 of the adjusting element 31 is slightly cambered and is in contact with the underside of the slide or flex bend. Due to the precise location of the slide or flex bend 25 in the support element 26 and the position of the point of contact of the actuating element on the flex bend, tilting is excluded and simple and time-saving adjustment is provided.
  • the shoe 30 is seated on the cylindrical surface 33 of an eccentric cam 34 which is mounted on a shaft 35 to rotate with the shaft 35 about the longitudinal axis of the latter when a setting motor 36 is actuated.
  • the motor 36 is a stepper motor that can be energized by a control unit 37 to rotate the shaft 35 through a number of steps determined by the unit 37.
  • the shaft 35 is mounted in the card frame (not shown) in order to be able to carry out the rotary movement about its own longitudinal axis, but no further movements.
  • the weight of the revolving cover assembly presses the flexible arch 25 onto the head 32 of the actuating element 31.
  • Further elements of this type can be provided to determine the curvature of the arch relative to the drum axis (not shown), or it only one adjustable element 31 can be provided per arch 25 - for example according to FIG. 13 of the previous application CH 1681/93.
  • a double of the arrangement according to FIG. 4 must be provided in mirror image on the other side of the card in order to be able to set the corresponding flexible sheet.
  • the carding distance can be automatically adjusted in a particularly simple and cost-effective manner during ongoing production; this avoids unnecessary downtimes.
  • the readjustment or readjustment of the carding distance can also be carried out depending on the grinding of a set, in particular on the automatic grinding of the reel set. This significantly increases the operating times of the carding machines in a spinning mill without having to accept significant losses in quality.
  • a suitable embodiment is described below with reference to FIG. 5. This figure corresponds to a combination of FIG. 2 from EP-A-565 486 with FIG. 13 from CH 1681/93 (EP 94 810 309.8) and with additions according to this invention.
  • the controlled grinding according to EP-A-565 486 is briefly described, reference being made to the entire EP document for details of the method and the arrangement.
  • FIG. 5 schematically shows the reel 40, beater 42, pickup 44 and the grinding system, which is indicated as a whole by the reference number 46.
  • System 46 includes a grindstone, its holder, a drive motor, and a Guide means (not shown) which guides the grindstone holder over the width of the card during a lifting movement. These latter elements are discussed in more detail in EP-A-565 486 and the description is not repeated here.
  • FIG. 5 also shows the drive motor 50 for the card, which rotates the reel 40, for example via a toothed belt 52, when the card is in operation.
  • the motor 50 is controlled by signals from a card controller 54 and reports its status back to this controller 54.
  • the card control 54 also controls the grinding system 46, it being assumed in the example shown that the grinding system is provided with its own "sub-control" 56, which carries out certain control functions autonomously on the basis of control commands from the main control 54.
  • the main controller 54 is provided with a display 58 and a keyboard 60 for human-machine communication.
  • This controller 54 also includes a time signal generator, which is indicated schematically at 62.
  • Figure 6 is a timing diagram and is used to explain the duration of each standby phase. This diagram is not to be understood as a realistic representation of reality, but as a purely fictitious diagram to explain principles.
  • Fig. 6 the time is plotted on the horizontal axis and the tooth wear of the drum set on the vertical axis.
  • the "curve” K1 represents the increasing tooth wear during a period T1 of uninterrupted operation with a predetermined drum speed and a certain processed material.
  • the “wear” is to be understood here as tooth wear, which leads to an impairment of the functionality of the tooth as a carding element. This is explained in more detail below with reference to FIG. 7. Under other operating conditions (drum speed, processed material) the wear is slower (e.g. after curve K2) or even faster (not shown), which leads to a steeper curve.
  • the operating time t (without using the grinding system) is the same as the standby period of the grinding system 46. During this period, the grindstone waits in its end position or is ready for use in this end position.
  • the period of time t can be entered by the operator into the controller 54 via the keyboard 60 (and can be called up again for control purposes via the display 58).
  • the "optimal" conditions can first be determined by test settings, and the determined values can then be firmly entered for normal operation.
  • the "optimal" waiting period t decreases over the life of a given clothing (i.e. until the card is refinished), i.e. the duration of this waiting period will often prove to be a function of the total operating time of the set.
  • This can be taken into account by the controller 54 using an operating hours counter (not shown) and messages from both the engine 50 and the time signal generator 62.
  • the motor 50 (which drives the drum) is only shown as an example as a source for the signals which drive the operating hours counter. Such signals could e.g. be removed from the customer drive and would therefore have a closer relationship to the material flow.
  • FIG. 7 shows diagrammatically two teeth 64, 66 of a set and their direction of movement P.
  • the work of the tooth is carried out at the tip S, and the wear at this point is decisive for the product quality.
  • Carding technology (product quality) depends on the sharpness of the tip on the leading edge of each tooth 64, 66, etc.
  • the tooth height is reduced in order to restore a sharp tip S1, S2 etc. on the front edge with every grinding operation. This can be continued up to a very low tooth height, eg up to the tip Sn (Fig. 7), where the tip is in the transition to the next tooth.
  • the card has a flexible sheet 70 on each side (only indicated schematically).
  • the machine frame (not shown) comprises a guide (not shown) for an actuating element 72, similar to the actuating element 31 (FIG. 4), for example, which cooperates with an eccentric cam 74.
  • the cam is rotated by a motor 78 by means of a shaft 76 when the motor 78 is controlled by the card controller 54.
  • the same controller 54 now controls both the grinding by means of the device 46 and the adjustment of the flexible sheets (of which only one such sheet 70 can be seen in FIG. 5) by means of the motors 78 (one per card side).
  • the preferred solution provides for adjustment after a grinding operation, namely after a number of carried out by the control Grinding operations.
  • the adjustment can only be triggered after several grinding processes, for example only when the tip S2 (FIG. 7) or even the tip S3 is reached.
  • the number of operations can be pre-programmed.
  • the adjustment also programmed then depends both on the number of operations mentioned and on the intensity of the grinding.
  • the use of the grinding system is not strictly controlled according to the time, but according to the production.
  • the user can enter the desired service life of the clothing, measured in terms of the amount of material produced (tons), into the control.
  • the controller can then determine how often grinding has to be carried out. This characteristic can only be adapted to the material type and / or the clothing type, or the appropriate type must be called up by the user from the memory. This characteristic in turn determines both the total number of grinding cycles (e.g. the double stroke of the grindstone) over the set service life of the set and the distribution of these grinding cycles over the service life.
  • the use of the actuator system to compensate for the effect of the grinding is of course not restricted to the combination with a grinding process controlled by the machine.
  • the user could input a signal into the controller that is a user-specified one Adjustment causes.
  • These signals could be defined according to an operating manual for grinding, even if a grinding device for grinding has to be mounted on the card and then removed again. Even preprogrammed "adjustment steps" could be triggered by the user, the timing of the adjustment being determined by the user himself.
  • the use of the actuator system to compensate for the effect of tooth wear is also not restricted to the solution according to FIG. 3.
  • the actuator can of course be used to compensate for the effects of wear on the clothing of the reel and / or the flat bars, i.e. the invention is not restricted to the consideration of wear on the drum sets.
  • a card which is conventional today has a considerable size - see, for example, the comparison values given in EP-A-446796. It is necessary to adhere exactly to the settings of the carding distance, namely at all points, ie over the entire working area of the flat bars. It is therefore desirable to guide the flexible sheet to several points and to adjust it when re-adjusting, as will now be explained with reference to FIGS. 8 to 12.
  • FIGS. 10 and 11 will be explained relatively briefly for the time being, since they are only used to explain terms that are used in the explanation of the other figures below.
  • the curve 80 in FIG. 10 represents the "impact circle” (or the "lateral surface") of the tips of the clothing 81 which is carried by the reel 4.
  • the curve 82 represents the percussion circle (or the lateral surface) of the tips of the clothing 83 which is carried by the flat bars 13 (FIG. 2).
  • the division of the set 83 in partial sets on the various flat bars 13 has been neglected, since this division is irrelevant for the necessary explanation. Because of this division, the effective impact circle is not a curve segment in practice, but a polygon that approximates a curve segment.
  • the carding distance KA is the distance from the impact circle 82 to the impact circle 80. This distance is usually intentionally variable over the length of the flexible sheet - it is relatively large at the inlet (where a flat bar comes into contact with the flexible sheet) and relatively small at the outlet (where the flat rod lifts off the flexible arch again).
  • FIG. 11 shows only one detail, on a larger scale, only a single flat bar 13 appears here with part of the “set” 83 according to FIG. 10.
  • the flat bar 13 has a sliding surface 84 which is mounted on a sliding surface 85 ( Fig. 8) slides on the flexible sheet 12.
  • the dimension ZH in FIG. 11 represents the tooth height or the distance between the impact circle 82 and the sliding surfaces 84 and 85, respectively.
  • the carding distance KA changes while the card is working, for reasons that are described in this description and in EP -A-384297, EP-A-627508 and DE-A-4235610 have been explained.
  • the task of the solution according to FIGS. 8 and 9 is to be able to intermittently restore the carding distance KA (including any variability along the flexible sheet) by compensating for the effects of wear while the card is still working.
  • the flexible sheet 12 according to FIG. 8 is guided at five points S1 to S5 (hereinafter referred to as “positioning points”) indicated by respective arrows or is supported with respect to the side plate 26.
  • the shield 26 comprises a bearing part 90 which defines the axis of rotation 92 of the reel 4.
  • a separate control element 31 is assigned to each control point S1 to S5, only one such control element 31 in FIG. 8 and another 31A in FIG. 9 being shown for the sake of simplicity.
  • the elements 31 at the setting points S1, S2, S3 and S5 each have a cambered head, on which the arch 12 is based, or against which the arch 12 is pulled by the element 31A at the setting point S3.
  • the latter element Fig.
  • the adjustment mechanism is the same for all elements 31, 31A, so that it is sufficient to describe only a single example.
  • This includes two lugs 96 that are attached side by side to the shield 26 (or molded with the shield in one piece) and a pin 97 that is rotatably supported between the lugs 96 about an axis of rotation 98.
  • the middle part of the pin 97 (between the lugs 96) has a cylindrical surface 99 (see FIG. 9) which is arranged eccentrically with respect to the axis of rotation 98.
  • Each adjusting element 31, 31A is provided with a connecting ring 100, which receives the eccentric central part of the pin 97 without play. When the pin 97 is rotated about the axis 98, the element therefore moves in one or the other radial direction with respect to the axis of rotation.
  • a guide (not shown) can be provided on the shield 26 to ensure linear movements of the element 31, 31A.
  • Each pin 97 is connected to a rotary lever 101 with the purpose of being able to exert a torque on it.
  • Each rotary lever 101 is assigned a respective rocker arm 102 which can tilt about an axis of rotation 104 carried by the shield 26.
  • the tilting movement of all levers 102 is accomplished by a common actuating device 106.
  • This device comprises a rail 107 which is guided in a guide (not shown) carried by the shield, in such a way that it can move about its axis 92 in its own longitudinal direction. Since the rail 107 is connected to each rocker arm 102 (e.g. at point 108, Fig. 8), the movements of the rail 107 are transmitted simultaneously to all levers 102 or to all elements 31, 31A.
  • a movement of the rail 107 is brought about by a suitable, controllable drive 109.
  • An electric cylinder with a distance measurement is suitable as a drive 109, the results of the distance measurement being able to be forwarded as control signals to a controller (not shown in Fig. 8, but see e.g. Fig. 5) via signal lines.
  • Fig. 8 shows the sheet 12 only on one side of the card.
  • a second bend 12 with its own elements 31, 31A, eccentric pins 97, levers 101, 102 and actuating device 106 is provided.
  • the two sheets 12 can therefore each be set individually (independently of one another). The principle of setting or tracking is explained below with reference to FIG. 12, this figure being understood as a purely schematic representation (without reference to the reality with regard to the mass of the elements).
  • the card is initially set in such a way that a sliding surface 85A of the flexible sheet is at the impact circle 80A of the drum set at operating temperature or operating speed is delivered. It is further assumed that the impact circle 80A is circular about the axis of rotation 92 (see also FIG. 8), the sliding surface 85A also being circular, or else being "adjustable" with respect to the reel, by a variable carding distance in the working area of the flat bars to achieve.
  • the drum set of the drum set shrinks to 80B during operation of the card (the dimensions have been greatly exaggerated in the interest of illustration).
  • the sliding surface 85 should "follow" the impact circle, but the carding distance (including any variability) should be kept as constant as possible.
  • the curvature of the sliding surface 85 must therefore be changed, at least to take into account the change in the curvature of the impact circle 80.
  • the sliding surface 85A must not only move vertically downward - it must also adapt to the changed radius of the impact circle 80.
  • control points S1 to S5 where the control elements touch the arc 12, must therefore move along the respective radii R1 to R5, which intersect at the axis of rotation 92, and they must all follow the same path ⁇ R, e.g. S1 -> S11, S2 -> S22, S3 -> S33, S4 -> S44 and S5 -> S55.
  • the path ⁇ R is equal to the radial distance between the impact circle 80A and the impact circle 80B.
  • the readjustment then does not contain any contribution to take into account any wear on the clothing of the flat bars 13.
  • the sliding surface 85 can be moved closer to the impact circle 80, so that the distance "a” between the The sliding surface 85A and the impact circle 80A is greater than the distance "b” between the sliding surface 85B and the impact circle 80B.
  • the last two procedures require differences in the tracking of the two card sides.
  • the device can of course be used if a conventional grinding method is used, e.g. if the drum set or cover set is ground by means of a grinding roller that extends across the width of the card.
