Definitions

  • the invention relates to a device and a method for setting at least one flexible sheet concentrically to a rotatably mounted garnished drum of a card, with at least one flexible sheet being arranged on both sides of the drum directly or indirectly on a side plate, adjustable by means of several setting points.
  • the carding gap of a card is determined by the distance between the clothing of the rotating flat bars and the clothing of the drum.
  • the flat bars run by means of sliding elements or pins on a sliding strip or a flexible bend, which form the guide track of the flat bars opposite the drum.
  • the sliding strips can be made in one piece or in two pieces. In the case of two-part sliding strips, these can have an upper wedge-shaped sliding strip and a lower wedge-shaped sliding strip.
  • the lower slide bar can be formed in one piece with the flexible bend. Since the wedge-shaped sliding strips are aligned with one another with their wedges, a displacement of the sliding strips with respect to one another causes a different height profile, which changes the distance between the upper sliding strip and the drum.
  • the slide strips can in turn be arranged on a flexible bend which is arranged directly or indirectly on both sides of the side plate of the card.
  • the sliding strips can also be arranged on the side plate of the card to be adjustable.
  • the concentricity and the distance of the Flexible bend and thus the sliding strips can be adjusted to the drum.
  • the term flexible bend also subsumes a sliding strip that is arranged directly or indirectly adjustable on the side plate of the card.
  • the setting of the flexible sheet concentric to the drum is the first step towards setting a constant carding gap.
  • the flexible bend is usually set by means of distance gauges, in that the distance is determined on the side edge area between the sets of flat bars and the set of the drum.
  • the contact and temperature control T-CON (DE 102006002812 A1) provides for an automatic shutdown.
  • opposing components that could collide with each other are electrically isolated and a voltage is applied to both components. He follows If there is contact between the components, a short circuit occurs, with a digital filter in the machine control system selecting and evaluating the number of contacts in order to prevent the card from being switched off immediately. So far, this system has been used to prevent clothing and machine damage, with the carding gap between the carding drum and the revolving flats being able to be readjusted during operation, especially when the temperature of the carding machine changes.
  • EP 2743385 B1 varies the present method in that the intensity or contact duration of each short circuit is determined and evaluated with the number of contacts determined.
  • the object of the invention is to improve the adjustment of the concentricity of the flexible bend or the sliding strip to the drum on a card. This object is achieved on the basis of a device and a method according to the preamble of claims 1 and 13 in conjunction with the characterizing features. Advantageous further developments of the invention are given in the dependent claims.
  • the device according to the invention for setting at least one flexible bend concentrically to a rotatably mounted garnished drum of a card has at least one flexible bend each for guiding a multiplicity of revolving flat rods Revolving cover system on both sides of the drum, the flexible arches being arranged directly or indirectly adjustable on a side plate by means of several adjustment points.
  • the invention is characterized in that there is a means with which at least one contact between the clothing of the flat rod and the clothing of the drum can be established so that a flexible bend can be set concentrically to the drum. Via the contact between the clothing of the flat bar and the clothing of the drum, a single flexible bend or both flexible bends can be set concentrically to the drum at the same time or one after the other.
  • a constant distance or contact between the clothing of the flat rod and the clothing of the drum can be established by means of a limited adjustment of the sliding strip in the area of the adjustment points of the flexible bend. If the flat bars run only on one upper side of the flexible bend, the flexible bend can be adjusted concentrically to the drum by means of the adjustment points. The concentric adjustment of the flexible arch to the drum takes place via the adjustment points. The setting of the carding gap takes place via the following setting of the sliding strip or the setting points of the flexible arch.
  • the means for determining the at least one contact between the clothing of the flat bar and the clothing of the drum can preferably be designed as an ohmmeter. With the ohmmeter, a constant distance between the sets can be determined indirectly by determining the electrical resistance. Adjusting the adjusting spindle changes the electrical resistance of the fittings.
  • the contacts between the clothing of the flat rod and the clothing of the drum can be determined by an electrical contact measurement, in which the clothing with the flat rod and the clothing with the drum are electrically isolated and a voltage is applied to both components, and via the contact at least one short circuit can be produced in both components.
  • the contact and temperature control T-CON is used for this purpose, by means of which the contacts are detected and assigned to a location.
  • a classic flat bar can be used to adjust the flexible bends, the set of which lies flat against the flat bar over the entire working width. It can be assumed here that the first contact does not necessarily take place in an edge region of the drum, but can also take place in a central region of the drum. In this case, the drum must stand still, which does not necessarily have to be the case with the other following variants, but can be useful due to possible collisions and clothing wear. If the first contact occurs, for example, in the middle area of the drum, the flexible arches can be readjusted on both sides in this position of an adjusting spindle until the number of contacts over the drum width or flat bar length has expanded and reached the edge area or can be determined. This process can be repeated in the area of each adjusting spindle so that the flexible bend is set concentrically to the drum via the cover travel. The carding gap can then subsequently be set by adjusting the sliding strips and, for example, readjusted depending on the temperature.
  • the at least one flat rod can be formed, at least one on a lateral edge area Take up spacer, which is designed to remove the set locally limited at a defined distance from the flat rod or to space it.
  • the setting points can be designed as manually or motor-driven adjusting spindles which are arranged on the side plate.
  • the lateral edge area is to be understood as the area of the flat rod in which the sliding elements or pins protrude laterally from the profile of the flat rod.
  • the spacer is designed in such a way that the set at the lateral edge area is approximately 1 to 5 cm away from the base area of the flat rod by a defined distance of, for example, 0.2 to 0.5 mm. is spaced, and after this 1 to 5 cm again flat against the rest of the flat bar.
  • a concentric distance or radius of the flexible bend arranged on both sides to the drum can be set so that the flat bar can be aligned absolutely parallel to the drum or to the drum axis.
  • the sets are therefore not subject to wear, since only the teeth or tips arranged on the side touch briefly in order to make the setting. This means that after the setting, all flat bars are moved parallel to the drum, so that no fiber fly can occur on the side and the carding quality across the drum width is equal to.
  • the spacers are removed again or the integrated spacers are moved back to zero so that the set rests flat against the flat bar again.
  • the set of the flat rod is preferably arranged detachably from the flat rod at least on a lateral edge region. Due to the detachable arrangement, a standard flat rod can be used, which is already in the card. For this purpose, the set is advantageously magnetically attached to the flat rod.
  • the set can be designed to be attached to the flat rod by means of segmented clamps or clips.
  • the clothing can be locally removed or spaced apart from the flat rod in the edge region at a defined distance.
  • the flat rod can be designed as a reference flat rod, in which the clothing is arranged at a lateral edge area at a varied distance from the drum, which protrudes from the plane of the rest of the clothing arrangement.
  • the spacer can preferably be designed as a separate shim that can be pushed or inserted between the set and the flat bar.
  • a flat rod located in the card can be used, in which, for example, a feeler gauge is inserted in a locally limited manner in the lateral edge area.
  • the spacer can be integrated in the flat rod. This can be done pneumatically or hydraulically Cushions are used that can only be activated manually or automatically for the setting process. Of course, this also presupposes that the clothing can be detached from the flat rod to a limited extent in the lateral edge area.
  • the spacer can be designed as a pressure or screw element which removes the set from the flat rod in order to set the adjustment points.
  • the pressure or screw elements can be integrated in the flat bar and limited to a defined dimension.
  • two flat rods are used to adjust the flexible bend, the first flat rod being designed to receive a spacer at a lateral edge area, and the second flat rod being designed to accommodate a spacer at a lateral edge area, which is opposite the edge area of the first flat rod lies. This means that the flexible bends, which are arranged on both sides of the drum on the side plate, can be adjusted at the same time.
  • the card has a control which is designed to store the contacts between the clothing of the flat bars and the clothing of the drum according to the location of the contact and to display them visually. This can be done at any number of points along the sliding strip. Documentation for setting the card is thus automatically implemented for the fitter and the customer.
  • the contacts are preferably determined by means of resistance measurement.
  • the electrical resistance between the sets of drum and flat bar can be used via an ohmmeter to set a concentric course of the flexible bends to the drum. If the resistance changes, the distance between the components has also changed. The adjusting spindle is then adjusted until the electrical resistance is the same at all adjustment points.
  • the contacts can be determined by means of an electrical short circuit, at least the sets of the flat bars and the set of the drum being electrically insulated and a voltage being applied to both components.
