  • the present invention relates to a method for automatically setting and maintaining a defined distance between a rotatably mounted drum and at least one further component of a textile machine, the drum and the at least one further component having a set or a separating knife, the drum and the at least one further components are connected to an electrical energy source, but are electrically isolated from one another.
  • the invention also relates to a textile machine.
  • the first calibration of the carding gap is carried out by hand on a cold, stationary card or card.
  • a feeler gauge is pushed by hand on individual flat bars between the clothing tips of the flat and the drum in order to determine the existing carding gap.
  • This process takes place for the fixed cover, which are then set to a predetermined distance, as well as for the revolving cover.
  • the determined carding gap then depends on a number of factors, including not insignificantly on the experience of the person making the adjustment. This results in a large measurement uncertainty, which continues in the further continuous determination of the carding gap by the machine control. Is the first calibration inaccurate, the subsequent automatic setting by the machine control cannot be more precise, since the measurement inaccuracies continue.
  • a small carding gap which is responsible for a high carding quality, cannot therefore be reliably set. If the setting is too imprecise and the carding gap is too small, a collision between the drum and the carding elements can occur if the temperature changes during operation. If the carding gap is set too large, the cleaning and carding of cotton fibers, for example, is insufficient, which has a direct effect on the yarn quality. The same situation occurs when calibrating the distance between the drum of a card or card and the components interacting with it, for example the fixed carding element, the doffer, the worker and turning rollers, the lickerins and the suction hoods.
  • the contact and temperature control T-CON system (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. 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 develop the existing textile machine, for example a card or card, with automatic calibration and setting of a defined distance between a component and the drum.
  • the method for automatically setting and maintaining a defined distance between a rotatably mounted drum and at least one further component of a textile machine, the drum and the at least one further component having a set or a separating knife requires that the drum and the at least one further Component connected to an electrical energy source, but are electrically isolated from one another. It is also assumed that the at least one component can be adjusted at a distance from the drum and can be moved automatically. When the drum is stationary or rotating, at least one component with its clothing or separating knife is brought into contact with the clothing of the drum and at least one electrical contact is established.
  • Contact does not necessarily have to be triggered by touching two components, but can also take place through conductive particles in the fiber material or through a flashover at a very short distance through the air. If the contact occurs through an electrically conductive particle or through a flashover through the air, the distance is well below the setting values for the carding gap. This distance between the at least one component and the drum is stored as a first reference value in the machine control.

  • the controller controls an actuator to generate the distance by means of a manipulated variable.
  • the process can be carried out with the drum at a standstill, in which case all components can be approached on contact with the drum.
  • the sets used and their assembly can be checked.
  • the drum can be ramped up to operating speed and at least one component with its clothing or separating knife again brought into contact with the clothing of the drum and at least one electrical contact can be made so that this distance between the at least one component and the drum as second reference value is stored in the machine control.
  • the machine control then provides a controller with a distance between the at least one component and the drum as a reference variable, the controller using a manipulated variable to control an actuator to generate a predetermined distance.
  • the system can be calibrated when the drum is stationary or rotating, by determining a reference value or zero value between the stationary or rotating drum and the at least one component. Based on this reference value, the at least one component can be moved at such a large safety distance from the drum that a collision of the component with the approaching drum is excluded.
  • the distance to be set between the component and the drum can correspond to a current carding gap. When the drum starts up, the distance between the drum and the at least one component is reduced due to imbalance, centrifugal force and the play in the bearings.

In this way, correct assembly and the correct selection of the set can be checked.
  • Another advantage is that fiber flocks are fed into the card or card after or when the drum is run up to operating speed.
