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 according to the preamble of claim 16.
- the conventional revolving flat card has a so-called flexible arch on each side provided, which is adjustable in relation to the corresponding side plate, around the carding gap (between the set of flat bars and the set of drum).
- the setting can be done manually according to DE-Gbm 9313633.
- a card is known from EP 0 627 508A1, which comprises a reel and to this adjustable parts, preferably having a nominal distance, such as a briseur, a stationary lid, revolving lid or customer.
- a sensor is provided.
- the sensor can be on the side of the arrangement or in be arranged an area that lies between the sides of the drum and the sensor can be carried by a flat bar.
- an adjustment actuator and a controller influencing the actuator system is provided, which controls the above-mentioned distance signal processed to control the actuators.
- the actuator system can be used to set a stationary one Cover element or to adjust the flexible sheet, etc. are provided.
- FIG. 1 shows a revolving flat card 1 known per se, for example card C50 Applicant, shown schematically.
- the fiber material is in the form of dissolved and cleaned flakes fed into the hopper 2, by a breeze or licker 3 as Cotton pad taken over, handed over to a drum or drum 4 and from a traveling cover set 5 parallelized, the opposite to the direction of rotation of the reel 4 is driven. Fibers from the fleece located on the drum 4 are then from a take-off roller 7 removed and in one consisting of different rollers Outfeed section 8 formed into a card sliver 9.
- This card sliver 9 is then one Tape storage 10 placed in a transport can 11 in a cycloidal manner.
- a section of the flexible sheet 12 of such a card is now shown with thereon revolving revolving covers 13 (only two shown) which are supported by a toothed belt 14 and a drive, not shown here, in the same direction or in the opposite direction to the direction of rotation of the drum 4 be moved slowly.
- Adjustment elements 15 are provided on this flexible sheet 12, with which the distance between the revolving cover 13 and the drum surface, the so-called carding distance, can be adjusted.
- the design of such control elements on the flexible elbow are for example from the German utility model DE-U-93 13 633 of the applicant known. In this case, however, the adjusting elements 15 are not only manually adjustable, but rather they can be automatically adjusted by means of actuators, for example small servomotors 17.
- Suitable Piezoelectric translators of the designation P-170 are for this task, for example to P-173 from Physik Instrumente GmbH & Co. in D-7517 Waldbronn.
- This actuator technology is included connected to a controller 16, which the setting of the flexible sheet 12, and thus the Carding distance determined; for example according to an adjustment characteristic according to FIG. 3.
- Fig. 3 a diagram is shown, the change in the carding distance K on the The abscissa is a function of the accumulated card sliver production P in tons (kg) on the ordinate for different processed material types.
- the curve S indicates the target distance, that is the carding distance, which is without wear on the drum set (and the revolving cover) would be given.
- a certain material to be processed influenced e.g. by dirt, fiber length and nits of the fed fiber material
- there is now a stronger or less in function of the production heavy wear as with curves a and b for the different fiber materials A and B. is made clear.
- the degree of wear depending on the current production for the different Provenance 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 actuators 15 can be adjusted based on this information.
- the current production of a card is a function of the delivery speed and the Band number.
- the total production of a card from a given point in time (e.g. from one Changing a set or a set service) is nowadays thanks to a programmable control determined by the machine and displayed on request, that is, such data is normally already present in the machine control.
- the "zero point" for calculating this Total production is of course also the zero point for controlling the adjustment of the carding distance usable.
- a prerequisite is that the elements to be adjusted are at the zero point are in a predetermined state, which is guaranteed by the operating personnel must become. Otherwise it becomes necessary to "start" the elements with a suitable one Monitor sensors and report them to the controller, which clearly shows the effort required elevated.
- the control can be programmed by the machine supplier with the adjustment characteristic, that means the characteristic is entered in the memory of the control. The user can then call up the appropriate characteristic by entering the material to be processed.
- the adjustment is preferably not made continuously, but intermittently (step by step) depending from the capabilities of actuators.
- the actuator system is preferably capable of reliably one Adjustment that is only a fraction (e.g. maximum 20%) of the normal carding distance represents. Such distances today are in the range of 20 to 30 hundredths of a millimeter. Preferably, the actuator system can reliably perform adjustment steps in the range of 1 to 3 hundredths.
- the system is best suited for the user who has a long period given material type processed.
- the calculation of the "total production" at frequencies Changing materials will prove difficult.
- time can be used as a control parameter instead of production become.
- the benefit means the effective production time in a given time period.
- Fig. 4 shows a modification of Fig. 1 of DE-Gbm-9313 633 to the motorized adjustment to be able to perform 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.
- Left is a Partial section through the reel 22 of the card and above is the profile of a flat bar 23 can be seen.
- This flat bar 23 lies with its head piece 24 on a bearing, here a sliding or flexible sheet 25 (also called flexible sheet), which in a support element 26 with U-shaped profile is kept almost free of play.
- the U-shaped profile is in the area of the Provide sliding or flexible sheet 25 with a precisely fitting gap so that it is almost jammed is held in the support member 26.
- Below the sliding or flexible arch 25 is the U-shaped one Profile of the support member 26 expanded so that the almost clamping effect mentioned - i.e. precise guidance - only necessary in the area of the sliding or flexible bend 25 is.
- the support element 26 is integral with one here connected only schematically indicated side plate 27, but it can also be an independent Be part, which in a known manner by means of screws or the like with the side plate connected is.
- a bore 29 is provided in the base 28 of the support element 26, in which an actuator 31 can move freely in its longitudinal direction.
- a shoe 30 is provided, which will be discussed in more detail below. Longitudinal of the adjusting element 31, a flat and narrow groove can be provided on the shaft thereof, in which is engraved with an adjustment scale, so that the adjustment of the sliding or flexible bow
- the setting element 31 and the shoe 30 are outside arranged on the drum plate, and therefore always easily accessible.
- the head 32 of the adjusting element 31 is slightly cambered and is in contact with the underside of the sliding or flexible sheet. Due to the precise location of the sliding or flexible sheet 25 in the support element 26 and the location Tilting of the contact point of the control element on the flexible bend is excluded and given a simple and time-saving setting.
- the shoe 30 sits on the cylindrical surface 33 of an eccentric cam 34 which is on a shaft 35 is mounted to rotate with the shaft 35 about the longitudinal axis of the latter when an adjusting motor 36 is operated.
- the motor 36 is, for example, a stepper motor that is operated by a control unit 37 can be excited to the shaft 35 by a number of steps determined by the unit 37 rotate.
- the shaft 35 is mounted in the card frame (not shown) to rotate about the own longitudinal axis, but no further movements.
- the weight of the revolving lid assembly (which is only partially shown here) pushes the Flexible sheet 25 on the head 32 of the actuating element 31.
- a double of the arrangement 4 must be provided in mirror image on the other side of the card to to be able to set the corresponding flexible sheet.
- the carding distance can be maintained during the running Automatically adjust production in a particularly simple and cost-effective way; in order to unnecessary downtimes are avoided.
- the readjustment or readjustment of the carding distance can also depend on the grinding of a set, in particular on automatic grinding of the drum set. So that the operating times the carding machines in a spinning mill significantly increased, without significant loss of quality to have to put up with.
- a suitable embodiment is described below with the aid of Fig. 5 described. This figure corresponds to a combination of FIG.
- EP-A-565 486 with the 13 from CH 1681/93 (EP 94 810 309.8) and with additions according to this invention
- EP-A-565 486 is briefly described, for details of the method or the arrangement is referred to the entire EP document.
- FIG. 5 shows schematically the reel 40, briseur 42, pickup 44 and the grinding system that is indicated as a whole by reference numeral 46.
- System 46 includes a grindstone its holder, a drive motor and a guide means (not shown) which the Grinding stone holder leads over the width of the card during a lifting movement. On the latter Elements is 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 drives the reel 40, for example Timing belt 52 set in rotation when the card is in operation.
- the motor 50 is through signals controlled by a card controller 54 and reports its status to this controller 54 back.
- the card controller 54 also controls the grinding system 46, in the example shown it was assumed that the grinding system was provided with its own "under-control" 56, which certain control functions autonomously based on control commands from the main controller 54 performs.
- the main controller 54 has a display 58 and a keyboard 60 for the human machine Provide communication.
- This controller 54 also includes a time signal generator, which is schematic is indicated at 62.
- FIG. 6 is a timing diagram and is used to explain the duration of each standby phase used. This diagram is not a realistic representation of reality, but rather to be understood as a purely fictional diagram to explain principles.
- Fig. 6 the time on the horizontal axis and the tooth wear of the drum set is on plotted on the vertical axis.
- the “curve” K1 shows the increasing tooth wear a period T1 of uninterrupted operation with a predetermined drum speed and one 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. In other operating conditions (drum speed, processed material) the wear is slower (e.g. after curve K2) or even faster (not shown), which results in a steeper curve.
- tooth wear has reached such a level at "N" that needs to be sanded. This is not an absolutely valid level, but can be obtained from the spinning mill in Depending on your production program (orders) determined at your own discretion become. The decision is e.g. based on the delivered card sliver quality, e.g. to the nits level.
- the (rather unrealistic) assumptions of the example shown result in the operating conditions of curve K1 a maximum operating time T1 and curve K2 a maximum operating time T2 until the card for card grinding (without using a built-in grinding system) would have to be shut down and partially dismantled. It is about one Much of this period T1 (or T2) worked with a significant degree of tooth wear Service. The grinding then causes an interruption U until the card again for another Period T1 (or T2) can start operating.
- the operating time t (without using the grinding system) is the standby period of the grinding system 46 equal. During this period, the grindstone waits in its end position or is in this end position ready for use.
- the time period t can be determined by the operator via the Keyboard 60 can be entered into the controller 54 (and again via the display 58 for control purposes be retrieved).
- the "optimal" conditions can first be determined by test settings and the determined values can then be entered for normal operation.
- the "optimal" waiting period t over the life of a given set i.e. until the card is refinished
- the duration of this Waiting period will often prove to be a function of the total operating time of the set.
- controller 54 using an hour meter (not shown) and messages be taken into account both by the motor 50 and by the time signal generator 62.
- the engine 50 (which drives the drum) is only shown as an example as a source for the signals which the Activate operating hours counter. Such signals could e.g. removed from the customer drive would 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. Die Work of the tooth is done at the tip S, and the wear at this point is for the Product quality is decisive.
- the technology of carding (the product quality) is of the Sharpness of the tip depending on the leading edge of each tooth 64,66 etc.
- grinding all Types
- the tooth height is reduced in order to have a sharp tip S1, S2 etc. to restore at the front edge. This can go down to a very low tooth height continued, e.g. to the tip Sn (Fig. 7), where the tip in the transition to the next Tooth pending.
- the card has a flexible sheet 70 on each side (only indicated schematically).
- the machine frame (not shown) includes a guide (not shown) for an actuator 72, similar to the Example of the actuating element 31 (FIG. 4), which works together with an eccentric cam 74.
- the Cam is rotated by a motor 78 by means of a shaft 76 when the motor 78 is off the Card control 54 is controlled.
- the same controller 54 now controls both of these Grinding by means of the device 46 as well as the adjustment of the flexible arch (of which only one 5 can be seen) by means of the motors 78 (one per card side).
- the preferred solution provides for adjustment after a grinding process, namely after a number of grinding operations determined by the control.
- the Adjustment can only be triggered after several grinding processes, e.g. only when the top S2 (Fig. 7) or even the peak S3 is reached.
- the number of operations can be preprogrammed become.
- the adjustment also programmed then depends on the number mentioned Processes as well as the intensity of the grinding.
- the grinding system is used not strictly controlled according to time, but according to production.
- the user can set the desired lifespan of the set, based on the number produced Enter the quantity of material (tons) in the control.
- the latter can then determine how often grinding has to be carried out in the controller's memory.
- This The characteristic must be adapted to the type of material and / or the clothing type, or it must the appropriate type can be called by the user from memory.
- This characteristic determines both the total number of grinding cycles (e.g. the double stroke of the grinding stone) about the set lifetime of the set, as well as the distribution of these grinding cycles over the lifetime.
- actuators to compensate for the effect of the grinding is of course not on the Combination with a grinding process controlled by the machine is restricted. It could e.g. a signal can be entered into the control by the user, one by the user fixed adjustment causes. According to the operating instructions for the Grinding can be set even when using a grinder for grinding on the card assembled and then dismantled again. There could even be preprogrammed "adjustment steps" are triggered by the user, the time of adjustment by the user is determined itself.
- actuators to compensate for the effect of tooth wear is also not limited to the solution according to FIG. 3.
- the use of the adjustment actuators only after production (without considering the material type).
- the actuator can of course be used to determine the effects of wear on the clothing of the drum and / or the flat bars, i.e. the invention is not based on the Limited consideration of wear on the drum sets.
- 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 drum 4.
- the curve 82 represents the impact circle (or the lateral surface) the tips of the set 83, which is carried by the flat bars 13 (Fig. 2).
- Fig. 10 is the division of the set 83 into partial sets on the various flat bars 13 has been neglected, since this division is irrelevant for the required explanation. Because of this division, the effective impact circle is not a curve segment in practice, but rather a polygon, but approaching a curve segment.
- the carding distance KA is the distance from impact circle 82 to impact circle 80. This distance is usually intentionally variable over the length of the flexible bend - it is relatively large at the inlet (where a flat bar is in contact comes with the flexible arch) and relatively small at the outlet (where the flat bar is again from the flexible arch).
- Fig. 11 shows only one detail, on a larger scale, only one appears here Flat bar 13 with part of the "set" 83 according to Fig. 10.
- the flat bar 13 has a sliding surface 84, which slides on a sliding surface 85 (FIG. 8) on the flexible sheet 12.
- the dimension ZH in 11 shows 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, namely out Reasons 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 set the one correctly Carding distance KA (including any variability along the flexible sheet) through the compensation to be able to intermittently restore the effects of wear and tear while the card still working.
- the flexible bow 12 according to FIG. 8 is indicated by five arrows Positions S1 to S5 (hereinafter referred to as "positioning points") or opposite the side plate 26 supported.
- the shield 26 comprises a bearing part 90, which the axis of rotation 92 from Drum 4 defined.
- a separate control element 31 is assigned to each control point S1 to S5, for the sake of simplicity only one such adjusting element 31 in FIG. 8 and another 31 A in FIG. 9 will be shown.
- the elements 31 at the control points S1, S2, S3 and S5 each have a cambered Head, on which the arch 12 is based, or against which the arch 12 from the element 31A at the set point S3 is pulled The latter element (Fig.
- the adjustment mechanism is the same for all elements 31, 31A, so that it is sufficient to use only one To describe copy.
- This comprises two lugs 96 which are attached to the shield 26 side by side are (or are cast in one piece with the shield), and a pin 97 between the lugs 96 is rotatably supported about an axis of rotation 98.
- the central part of the pin 97 (between the lugs 96) has a cylindrical surface 99 (see FIG. 9) which is opposite the Axis of rotation 98 is arranged eccentrically.
- Each actuator 31, 31A is with a connecting ring 100 provided, which receives the eccentric central part of the pin 97 without play. At the Rotating the pin 97 about the axis 98 therefore moves the element in one or the other other radial direction opposite the axis of rotation.
- a guide (not shown) can be on the shield 26 can be provided to ensure linear movements of the element 31,31A.
- Each pin 97 is connected to a rotary lever 101 with the purpose of applying torque to it to be able to exercise.
- Each rotary lever 101 is assigned a respective rocker arm 102, which moves around an axis of rotation 104 carried by the shield 26 can tilt. The tilting movement of all levers 102 is accomplished by a common actuator 106.
- This device includes a rail 107 which is guided in a guide (not shown) carried by the shield, and 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 location 108, Fig. 8), the Movements of the rail 107 simultaneously to all levers 102 and to all elements 31.31 A. transfer.
- a movement of the rail 107 is brought about by a suitable, controllable drive 109.
- a suitable, controllable drive 109 On Electric cylinder with a distance measurement is suitable as drive 109, the results of Distance measurement as control signals to a controller (not shown in Fig. 8, but see e.g. Fig. 5) can be forwarded via signal lines.
- Fig. 8 shows the sheet 12 only on one side of the card.
- a second one Bow 12 with its own elements 31.31A, eccentric pins 97, lever 101.102 and actuating device 106 provided.
- the two arches 12 can therefore each individually (independently of one another) can be set.
- the principle of adjustment or tracking is as follows explained with reference to FIG. 12, this figure as a purely schematic representation (without reference to Reality regarding mass of the elements).
- the card is initially set so that at operating temperature or operating speed the impact circle 80A of the drum set a sliding surface 85A of the flexible bow is delivered. It is further assumed that the impact circle 80A is circular around the axis of rotation 92 (see also FIG. 8), wherein the sliding surface 85A can also be circular or opposite the reel can be "adjusted" to a variable carding distance in the work area To achieve flat bars.
- the drum set of the drum set shrinks during operation the card on 80B (the masses have been 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 merely be vertically downwards drive - it must also adapt to the changed radius of the impact circle 80.
- control points S1 to S5 where the control elements touch the sheet 12, must therefore be move along the respective radii R1 to R5 which intersect at the axis of rotation 92, and they must all follow the same route DELTA R, e.g. S1 -> S11, S2 -> S22, S3 -> S33, S4 -> S44 and S5 -> S55.
- DELTA R is the radial distance between the impact circle 80A and the impact circle 80B.
- the new setting does not contain any contribution to the possible wear on the set the flat bars 13 to be considered.
- the Slide surface 85 are moved closer to the impact circle 80, so that the distance "a" between of 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 Apparatus can of course be used when using a conventional grinding process e.g. if the drum set or cover set by means of a across the width of the Carding extending grinding roller is ground.
