Definitions

  • the present invention relates to a method and an apparatus for adjusting the working gap between the points of the flat clothings and the points of the cylinder clothings of a carding machine, with the flat rods provided with clothings being guided over a partial zone of the cylinder circumference on either side of the carding machine on respective convexly arched sliding guides, and the flat rods are provided with flat heads comprising sliding surfaces, which flat heads slide along the sliding guides.
  • the old US patent specification 528007 of 23 October 1894 describes a revolving flat card in which the flat rods which are provided with flat clothings are fastened at their ends to respective endless chains and are pulled by means of said endless chains over sliding guides provided at either side of the carding machine, so that the clothing points are moved relative to the clothing points of the cylinder and at a constant distance from the same over a partial zone of the circumference of the cylinder and thus perform the desired carding work.
  • the flat rods After the movement along the sliding guides the flat rods are deflected about a pair of chain wheels and guided back to a further chain wheel which is also used as a deflection point. In this way they reach the sliding guides again, so that they can perform the desired carding work again with the clothing points of the cylinder.
  • the flat rods will repeatedly reach the sliding guide and will repeatedly perform the carding work with the cylinder.
  • So-called flat heads are provided at the ends of the flat rods which are provided with sliding surfaces which slide on the respective sliding guides on either side of the carding machine. Said sliding surfaces determine in combination with the sliding surfaces of the sliding guides the distance between the points of the flat clothings and the points of the cylinder clothings. This distance must be adjusted precisely in the production of the card and when the carding machine is newly clothed.
  • carding distances i.e. distances between the points of the flat clothings and the cylinder clothing, are desirable in the range of approx. 0.2 mm. High-quality carding work at high production of the carding machine is only possible then.
  • the sliding guide in the carding machine is radially adjusted according to US-PS 528007 with respect to the rotational cylinder axis in order to maintain the desired carding distance.
  • the sliding guides are arranged as so-called flexible bends which are attached according to the US patent specification at three different places by means of adjusting rods to the side frame of the card frame.
  • the adjusting rods which are arranged as threaded rods with left-handed and right-handed threads, the three points on which the adjusting rods act upon the flexible bend can be adjusted with respect to the card frame and thus the cylinder axis. It is necessary to understand that as a result of the radial adjustment at three circumferentially distributed points, the curvature of the flexible bends, i.e. the sliding guides, is changed slightly, meaning that there is a bending of the flexible bends.
  • the carding machine After adjusting the carding distance along the sliding guides, the carding machine can be put into operation. In the course of time the points of the flat clothings and the cylinder clothings are worn off, so that the carding distance increases in an undesirable manner. In order to counteract said enlargement of the carding distance, all adjusting rods can also be adjusted jointly in the old US patent specification 528007 in order to return the carding distance to the originally provided value.
  • the adjustable rods are not fastened directly to the side frame of the card frame at their ends averted from the flexible bend, but instead to the respective arms of angle levers which are mounted rotatably on the side frames of the card frame.
  • the other arms of the respective angle levers are connected mutually and with an adjusting wheel via respective connecting rods, so that by turning the adjusting wheel there is a common adjustment of the angle levers and thus the respective points of attack of the adjusting rods on the flexible bends by way of the adjusting rods.
  • a change in the settings of the flexible bends is not only necessary in the case of wear and tear of the flat clothings and cylinder clothings, but also after the grinding of the cylinder or flat clothings.
  • SACM offered a carding machine around 1975 for example in which the adjustment of the flats was performed on each side of the machine from a single point by means of two adjacent and mutually displaceable spirals.
  • the outer spiral is provided on each side of the carding machine with the shape of an long stretched-out bent wedge with a small wedge angle whose outside surface forms the sliding guide and whose inner radial surface slides on the radial outside surface of the respective inner spiral.
  • the inner spirals are also provided with the shape of a long stretched-out bent wedge, but are provided in addition on the radial inner side with teeth and can thus be turned by means of a pair of toothed wheels about the axis of the cylinder, so that as a result of the cooperation of the radial outside surface of the inner spiral with the respective radial inner surfaces of the outer spirals, the sliding guides can be adjusted simultaneously on both sides of the carding machine.
  • DE-A 29 48 825 provides a method to control the working conditions between two working elements provided with a pointed clothing, e.g. the cylinder and the revolving flat of a revolving flat card, in which a value which is in direct connection with the dimensions of the cylinder is detected continuously or temporally and the carding distance is kept to a certain value by a suitable control means depending on the detected value.
  • a pointed clothing e.g. the cylinder and the revolving flat of a revolving flat card
  • the concrete solution shown there uses heatable metal rods for adjusting the flexible bends, i.e. the sliding guides, which are heated either by means of a fluid heatable by a heat supply apparatus or an electric heating and are therefore caused to undergo a thermal extension. Since the temperature control allows a relatively precise setting of the lengths of the respective metal rods, the device as described there can work with a high precision.
  • US-PS 5,625,924 shows a carding machine with different possibilities for the radial adjustment of the sliding guide.
  • this specification describes the application of controllable actuators which are triggered specifically to newly and periodically set the working elements and to compensate the change of the carding gap as a result of wear and tear to the clothings or after a grinding process. It is expressed that the controllable actuator can be used and controlled in connection with the built-in grinding system. Different arrangements of the actuator are indicated. For example, the application of servomotors or piezoelectric translators for performing the adjustment is mentioned. It is also shown how an eccentric arrangement can be used by a controllable drive mechanism to perform a smooth adjustment.
  • An adjusting system is further known from the WO 93/07314 with several adjusting devices which are arranged at respective places along the sliding guide and which extend between the sliding guide and a fixed reference point, with each adjusting device comprising a blocking mode in which an adjustable clamping device is active in order to maintain a once reached setting by way of clamping.
  • a plastic deformation occurs in some materials already at lower tensions, which also leads to an imprecision of the adjustment.
  • the pretensions which are used in working the flexible bend can have a disturbing influence on the precision of the setting.
  • the adjustment range for all even settings is usually in the range from 0.2 to 0.3 mm.
  • the individual adjusting devices are supported on relatively rigid constructions such as the side frames of the carding frame or so-called fixed bends which in principle also form an element of the side frame of the carding frame.
  • the setting of the working gap is performed by changing the radial height of the sliding surfaces of the flat heads with respect to the points of the respective flat clothing.
  • an adjusting device is provided in or on each flat head whose radial height is set for the purpose of setting the working gap.
  • an adjusting device in or on the flat heads of the flat rods it is managed to achieve a substantial simplification in the area of the flexible bend.
  • the same can be aligned only once precisely with respect to the rotational axis of the cylinder during the production of the carding machine, e.g. in such a way that the convexly arched sliding guides are disposed concentrically to the rotational axis of the cylinder or extending wedge-like with respect to an imaginary circle disposed concentrically to the rotational axis of the cylinder, so that the working gap between a flat clothing and the cylinder clothing decreases over the length of the sliding guide in the manner as is known per se. All settings made thereafter of the working gap can be made by settings of the adjusting devices of the respective flat heads.
  • This type of setting which can be used for the above-mentioned cases a), b) and c) is simpler as compared with previous methods in the respect that it can be performed by an exchange of spacer elements outside of the carding machine, namely by employing a gauge which considers the position of the clothing points of the cylinder, which can easily be measured again from the outside, optionally after removing a flat rod, with respect to the radial position of the convexly bent sliding guides.
  • this type of adjustment can be used both for coarse setting as well as for the fine setting to the extent that it is ensured by a precise working of the sliding guides that the same are disposed concentrically to the rotational axis of the cylinder or have the desired position with respect to the rotational axis of the cylinder.
  • each adjusting device concerns a piezoelectric device which is adjusted electrically to determine the radial height of the flat head.
  • piezoelectric devices which allow adjustments up to a number of millimeters (e.g. DE-A 198 33 782 describes a piezoelectric adjusting device in form of a drive arrangement for a writing head which achieves adjustments in the range of up to 2 mm), the use of piezoelectric adjusting devices allows both performing the coarse setting according to item a) as well as the settings according to items b), c) and d).
  • the realization of the coarse setting according to item a) means under certain circumstances, however, that every piezoelectric device must be triggered separately in order to ensure different adjustments in the respective flat heads.
  • an adjusting device in accordance with the invention is that the same is realized as a resilient device whose radial height with respect to the rotational axis of the cylinder is set by changing the tension of the belts which are provided for moving the flat heads along the sliding guides.
  • such an adjustable device can concern a spring, with the degree of compression of the respective spring being changeable by the belt tension.
  • a controllable brake may be provided which acts directly or indirectly at one of the deflection points of the endless belt on the toothed disks provided there.
  • the motor which causes the drive of the toothed disks which produce the drive for the endless belts concerns a type of motor which always tries to supply a constant drive output, it is sufficient to work with such a controllable brake. If the drive output of the motor decreases with rising load, it may be advantageous to keep the drive output of the motor also controllable, so that in interaction with the controllable brake the belt tension in the zone of the convexly bent sliding guides and therefore the degree of compression of the spring can be kept constant and adjustable.
  • Fig. 1 shows in a side view a revolving flat card 10 as is known, e.g. the carding machine C50 of the applicant in a schematic representation.
  • the fiber material to be carded which can consist of natural fibers or synthetic fibers or mixtures thereof is supplied in the form of opened and cleaned flocks to the filling box 12, received by a licker-in or taker-in 14 as lap feed, transferred to a swift or cylinder 16 and parallelized by a set of revolving flats 18 which is driven via deflection pulleys 20, 22, 24, 26 in opposite direction to the direction of rotation 28 of the swift 16.
  • Fibers from the nonwoven disposed on the swift 16 are removed by a doffer 30 and formed into a card sliver 34 in the known manner in an outlet section 32 consisting of several rollers. Said card sliver 34 is then deposited by a coiler 36 in a transport can 38 in a cycloidal manner.
  • Figs. 2 and 3 show the card of fig. 1 in the zone of the set of revolving flats on an enlarged scale and in further detail.
  • individual flat rods 40 are shown which all consist of a supporting body 42 which is arranged as a hollow profile and carries the flat clothing 44, as well as two end heads 46 which are attached to the respective ends of the hollow-profile-like supporting body, e.g. in such a way that they are inserted in the ends of the hollow profile and are connected with the hollow profile in a positive-locking way by a squeezing process which is described in detail in EP-A-627 507.
  • the concrete preferred arrangement of the flat heads 46 and the drive belts 48 which drive the same is described in EP-A-753 610.
  • the belts can be arranged especially according to fig. 4 of the present specification. This arrangement is also shown in fig. 4 of the present application in further detail in a schematic exploded view.
  • Belt 48 is provided on one side, namely the inner side of fig. 2, with teeth 48A which engage in teeth 48B of the toothed disks or toothed wheels 20 and 26, with only few teeth 48A and 48B being shown for illustration reasons. It is understood, however, that the entire inner side of the belt 48 is provided with teeth 48A and the entire circumference of the toothed wheels 20 and 26 are provided with respective teeth 48B.
  • the sliding surfaces 64 of the flat rods 46 are disposed in the zone of the flexible bend 54 in sliding contact with the same, namely as a result of its own weight on the one hand and due to the belt tension on the other hand which in the zone of each flat head produces a radially inwardly directed force. In other words, they are pressed by the tension of the drive belt 48 and due to their own weight against the sliding guide 52, i.e. against the sliding surfaces 66 of the flexible bend 54. In this way the required carding distance A (fig. 3) between the flat clothings 44 and the cylinder clothing 68 is ensured.
  • the flat rods 40 Due to the positive-locking engagement of the pairs of beams 49 of the drive belt 48 in the respective openings 41 of the flat heads, and due to the synchronized revolving of the drive belts 48 on both sides of the carding machine, the flat rods 40 are moved in a synchronized way over the two flexible bends 54, with the longitudinal axes of the flat rods 40 always being guided parallel to the cylinder axis.
  • the positive-locking engagement between the drive belts 48 and the flat heads 46 transmits the tensile forces of the drive belts 48 onto the flat rods 40, so that they are moved along the carding path between the inlet point 50 and the outlet point 56.
  • a brake disk 25 and brake nippers 27 which can be controlled by a control unit 29 in such a way that a controlled brake force can be exerted on the toothed wheel 26 (and via shaft 182) on the respective toothed wheel on the other side of the carding machine, as a result of which it is possible to determine the belt tension on both sides of the carding machine and therefore the pressing pressure between the flat heads and the sliding guides 66, as will be explained below in closer detail.
  • a particularity in the proposal according to EP-A-753 610 is that in the zone of the deflection the beams of the pairs of beams 49 of the drive belts 48 have a tendency to straddle apart and to hold the flat heads 46 in such a way that they are deflected about the toothed wheels 20, 26 without there being any danger that the flat rods 40 are lost and without additional guide means being necessary in these zones.
  • the flat rods 40 rest loosely on the upper strands of the drive belts; they can thus be easily detached from the drive belt 48 when they need to be especially cleaned or exchanged. Gravity ensures that the flat rods 40 will not separate from the drive belts 48 in this zone in an undesirable manner.
  • the flexible bends 54 of the sliding guides 52 will ensure defining the carding distance A between the flat clothings 44 and the cylinder clothing 68 which are shown for reasons of illustration only in sections in figs. 3 and 4.
  • the sliding guides in this example are equipped with an embedded beltlike guide element 70 made of plastic which forms the slide surface for the flat heads, as is described in closer detail in DE-A-39 07 396 or EP-A-0 620 296.
  • an embedded element or embedded elements which are subdivided into sections can be used in all embodiments in accordance with the invention as explained below in order to form the actual sliding surface 66 for the flat heads 46.
  • Such an element can also be omitted, however, especially when the flat head is provided with a sliding block or sliding lining which slides on the sliding guide which usually consists of metal.
  • each sliding guide 52 also comprises a radial inner support 72 which is frequently also known as a fixed bend, with each radial inner support 72 being rigidly connected with the respective associated side frame 74 of the carding machine or being integrally arranged with the same, e.g. in form of a respective cast part.
  • the side frames 74 of the carding machine also carry the rotational shaft 62 of the cylinder (not shown in fig. 3) and also form a radial guide means for the flexible bends 54 (not shown).
  • an inner part 78 provided with an external thread
  • an outer part 80 arranged as a threaded bush with inner threads.
  • the curvature of the respective flexible bend 54 can be adjusted to the curvature of the cylinder and the radial position of the sliding surface 66 and the respective flexible bends 54 can be set in such a way that the carding distance A remains constant over the entire length of the carding path and over the entire width of the cylinder, or ⁇ if desired ⁇ is provided with the desired course along the carding path.
  • Fig. 5 shows a face view at first which as seen approximately in the direction of arrow V in fig. 4 shows a flat head 146 which is also provided with a hollow space 141 for receiving the pairs of teeth 49 of the drive belt.
  • a spring clip 190 is provided with two resilient legs 192 which engage in respective undercuts 194 in the side parts 147 of the flat head 146. Due to the inclined flanks of the undercuts 194 the spring clip 190 always tries to slip upwardly in fig. 5 and holds in this way a plate-like spacer element 196 between its lower zone 198 in fig. 5 and the lower side 199 of the main body of the flat head.
  • the spring clip is of an at least substantially constant cross section in this embodiment and extends in the direction perpendicular to the illustration of fig. 5 over a length which corresponds at least substantially to the width B of the sliding guide 52.
  • the distance A can be newly set.
  • the spring clips can be loosened and removed easily for exchanging the spacer elements 196.
  • the lower side of the spring clip 190 forms in this example the actual sliding surface 164 of the flat head and can be provided for this purpose with a hard surface or with a sliding lining.
  • the use of different spacer elements 196 allows changing the radial height (relating to the rotational shaft of the cylinder) between the points of the flat clothings 44 and the actual sliding surface 164, i.e. in this example the lower side of spring clip 190, and thus to set the working distance A.
  • the belt tension leads to a force component which presses the flat heads 146 of the flat rods against the sliding surfaces 66 of the sliding guides 52. Since one is able to provide this force variably according to the invention, one can also determine the degree of compression of such spring elements 196 and thus also the working distance A.
  • the belt tension can be determined according to the pressing pressure of the brake nippers 27 on the brake disk 25 which is determined by control unit 29, and thus the magnitude of the force component acting in the radial direction on the flat heads.
  • the drive motor 61 concerns a type of motor which always tries to maintain a predetermined speed and therefore increases the driving torque according to the respective load in order to maintain the required rotational speed, no special control unit is required for the drive motor 61 other than a control unit which ensures the required rotational speed (if the rotational speed belongs to the predeterminable parameters).
  • the drive motor 61 may be advantageous to provide the drive motor 61 with a control unit 62 which ensures a constant drive torque at constant speed, e.g. by changing the amplitude of the voltage applied on the motor or by controlling the drive current.
  • the embodiment according to figs. 6, 7 and 8 also uses spring elements which in this case are in the form of leaf springs 296 which are disposed between a fixed part 300 and a movable beam 302 of the flat head 246, namely to the left and right of the hollow space 241, receiving the pairs of teeth 49 of the endless belt 48.
  • Each movable part 302 of the flat head 246 is held displaceably on the shaft part 304 by two guide pins 306 for the purpose of displacement according to the double arrow 308.
  • the threaded part 301 of each guide pin 306 is screwed into the fixed part 300 of the flat head 246, so that a shoulder of the guide pin rests fixedly on the fixed part 300.
  • each guide pin is housed in a circular recess 305 of the movable part 302.
  • the lower side of each movable beam 302 forms in this example the sliding surface 264 of the flat head in the zone between the recesses 305.
  • a gap space 307 is situated between the movable beam 302 and the fixed part 300, in which space there is housed a spring element 296 which is bent in the manner of a leaf spring, with each leaf spring 296 having two openings 309 arranged as oblong holes through which projects one each of the guide pins 306. In this way the springs are held captively and can be freely compressed or stretched in the desired amount without being hindered in their respective movements by the guide pins 306.
  • Fig. 7 also shows the part 311 of the flat head which is received within the hollow section 42 of the flat rod 40.
  • the recess 313 which receives the belt part of the belt and ensures that the flat heads are guided laterally by the endless belts.
  • Fig. 9 shows an embodiment which is very similar to the embodiment according to figs. 6 to 8, which is indicated by the applied reference numerals.
  • the only difference in this case is the provision of a friction lining 315 on the lateral zones of the fixed part 400 which are opposite of the movable beam 402.
  • the fiction linings 315 act in an energy-absorbing way and prevent oscillations in the springs leading to changes in the working distance A.
  • they could optionally also be attached to the movable beam 402.
  • spacer elements (not shown), could be inserted into the gap spaces in order to either perform the setting a) or to compensate possible differences of the spring properties.
  • the embodiment according to figs. 10 to 13 shows an alternative embodiment of a flat head 446 which in this case too consists of two parts, namely a part 500 which is fastened to a hollow carrier 442 of the flat rod and is thus designated as a fixed part and a movable part or beam 502 which is connected to the fixed part 500 by way of a piezoelectric adjusting device 496.
  • the piezoelectric device 496 consists in this case of a plurality of piezoelectric layers which change their thickness by applying a voltage and thus cause the desired change in the radial height of the sliding surfaces 499 of the flat head 446 with respect to the clothing points of the flat rod 40.
  • a voltage is applied to one side of the piezoelectric device 496 via a conducting track 519 which is integrated in the endless belt 448 and extends at least partly completely through the belt, whereas the other side of the piezoelectric device 496 and the sliding guides 52 of the carding machine are applied to a ground.
  • wires can be integrated in the flat head, as is shown in 523, in order to avoid voltage losses which would occur under certain circumstances depending on the material of the flat head.
  • the conducting track is provided at either side of the endless belt 519, there can be a contact making with the conducting track on the inner side of the endless belt for the purpose of contact making with the voltage source or with the control device which determines the level of the voltage and therefore the amplitude of the change in dimension of the piezoelectric device 496.
  • This can be performed by way of brush-type contacts or respective conductive zones can be provided on the toothed wheels which are in connection with a voltage source or a control device via brush-type contacts.
  • zones of the toothed wheels When zones of the toothed wheels are used for the voltage transmission it must be ensured that the respective zones are insulated from the remaining zones in order to avoid any shorts.
  • Fig. 12 shows that the piezoelectric device is N-shaped in a top view according to the shape of the flat head 446.
  • Fig. 13 also shows that there is a gap, which can also be provided with insulation, between the two parts 500 and 502 of the flat head 446 in order to prevent shorts in this case as well.
  • the hollow space 41, 141, 241, 341 and 441 is open on the outside face side, but closed on the rear face side by the material of the flat head. It is not mandatorily necessary, however, to provide such a hollow space. It is only provided here because endless drive belts with pairs of teeth are used which engage in hollow spaces.
  • the spring device or piezoelectric device can be defined differently in order to consider the respective shape of the flat head. When providing a hollow space the outside face side of the flat head can be closed off.
  • a respective modified shape of the spring device or piezoelectric device is also possible, e.g. such that the piezoelectric device 496 of fig. 12 is provided then with the shape of a rectangle with a rectangular opening in the middle.
  • the piezoelectric device used here is represented as a plurality of piezoelectric layers, the piezoelectric device can be realized in a completely different way, e.g. according to the aforementioned German patent application 196 51 894 A1, It can then have a completely different orientation in the flat head.
