Definitions

  • Combers are used to comb out unwanted (short) fibers from a number of slivers and to feed the combed slivers thus obtained to a common drafting system. There, the slivers are stretched together so that a single sliver with predetermined properties is produced, which is usually deposited in a can.
  • these machines can be matched to textile machines downstream in the production chain, such as roving frames and spinning machines, but this is done on the combing machines themselves.
  • sliver breaks very often occur in the downstream textile machines. Although this is automatically eliminated, particularly in spinning machines, the frequency of such breaks may be of interest in order to be able to draw conclusions about the quality of the fiber material to be drawn, the drafting unit settings of the respective combing machine and the like.
  • each machine In order to monitor combers, each machine must be monitored individually. There is a display and operating terminal on each comber for this purpose. This is particularly necessary in order to be able to stop the combing machine if, for example, a fault has occurred or empty tape cores have to be exchanged for tape cores, i.e. cores provided with windings, and to be able to restart when a fault has been eliminated or the new one Fiber material can be processed.
  • a person always has to go to the terminal if they want to know which parameters are set, the state of the combing machine and/or the processing stage it is in. In particular, it is known to be able to display operating parameters of such a combing machine by means of buttons generated by software on such a terminal with integrated, simulated light point strips.
  • a winding filling level i.e. the condition of a tape winding with regard to the fiber material still on the associated sleeve
  • the controller is set up to operate at least one lighting element according to a predetermined lighting scenario that optically separates the delimitation of two immediately adjacent display areas.
  • each display area can be assigned to a respective can parking space.
  • each display area can be associated with a respective fiber sliver in relation to an associated combing head on a sliver lap upstream of the combing machine. It is thus clearly recognizable in relation to which sliver lap the sliver breakage occurred. There is no need for a time-consuming search for the tape winding arrangement.
  • FIG. 5 shows a lighting scenario, in which the so-called CV value of the combed traffic convoy is displayed.
  • the outer two light-emitting elements (light-emitting element groups 15) are used for optical delimitation.
  • the light element group 14 lights up green and serves as an indication that the CV value is correct in this area.
  • the brightly lit light elements 14a indicate that the current CV value has not yet reached the limit shown on the right.
  • Light elements 14b that glow dark green indicate here that the CV value has not (yet) reached this range.
  • the lighting elements 17b belonging to the lighting element group 17 are switched off and signal the absence of an increased CV value. If the current CV value exceeds the permissible limit, light elements of light element group 17 are gradually switched to bright red from left to right.
  • FIG. 6 shows a lighting scenario for displaying the sliver number deviation of the combed sliver from a preset desired value.
  • a central group of two light-emitting elements (light-emitting element group 15) is used to distinguish whether the volume number deviation is positive (groups 14, 17 of light-emitting elements arranged to the right) or negative (lighting elements of groups 14, 17 arranged to the left). If there are no brightly lit light-emitting elements 14a, this means that there is no band number discrepancy.
  • a switch is preferably made to a lighting scenario according to FIG.
  • the respective determined sliver breakage is signaled according to the upper lighting state by means of yellow luminous lighting elements (lighting element groups 16). All light-emitting elements now change to the light-emitting color yellow (a light-emitting element group 16) and back to the light-emitting state shown above. Instead of the light-emitting element group 16, a light-emitting element group 17 can also be used, which then warns more clearly in red.
  • the upper and lower rows of luminous elements can also be swapped and adjusted by the operator of the comber.
  • a pot 6 is now being filled, this is signaled by means of a row of light-emitting elements 14a located in relation to the light-emitting element group 14, which becomes larger and larger from the left.
  • the pot 6 is filled, so that all lighting elements between the left lighting element group 15 and the lighting element group 14b light up light green (lighting elements 14a).
  • the can change is now completed.
  • two light-emitting elements to the left of the light-emitting elements 14a are once again actuated to emit dark green.
  • the can change can also be implemented using the lighting scenario shown in FIG.
  • the light-emitting elements arranged between the light-emitting element groups 15 change periodically between glowing yellow (light-emitting element group 16) and not glowing (light-emitting element group 13).
  • a display of the status of the belt suction can be implemented, for example in the form of the deviation of a present actual suction pressure from a preset target suction pressure (range).
  • the lap fill level is displayed, for example, as a summation across all combing heads.
  • a lighting scenario can also be implemented, by means of which the occupancy of the can stands of the can changer of the combing machine 1 can be identified. Analogously to FIG. 7, the display can then have areas which are optically separated from one another and which represent a respective can parking space.
  • Brightness control can be applied anywhere.
  • the invention can also be applied to all other textile machines with a drafting system with regard to the lighting scenarios that only relate to the drafting system, ie in particular to drawframes, tape winders, roving frames and spinning machines. All light scenarios can be applied to the lights 10 relating to the individual combing heads. i.e. the lamp 10 on the drafting system hood 4 can then display states, parameters and processes relating to the entire combing machine 1 and/or the drafting system, while the other lamps 10 display states, parameters and processes relating to the respective combing head.

Abstract

L'invention concerne une peigneuse (1) ayant une unité d'étirage et une section de fonctionnement, qui est conçue pour peigner et étirer un matériau fibreux sous la forme de rubans, et pour délivrer ceux-ci à une section de traitement telle qu'un bobinoir. La peigneuse comprend également une section d'affichage comprenant une pluralité d'éléments d'éclairage (12 ; 13 ; 14, 14a, 14b ; 15 ; 16 ; 17, 17a, 17b). La peigneuse (1) comprend un dispositif de commande ou est couplée à celui-ci, le dispositif de commande étant conçu pour commander la section de fonctionnement selon des paramètres de fonctionnement prédéterminés spécifiés pour le fonctionnement de la peigneuse et pour commander les éléments d'éclairage selon un scénario d'éclairage prédéterminé. Les éléments d'éclairage sont commandés de façon à indiquer : un état dans le processus d'aspiration de ruban de la peigneuse ; un écart dans le nombre de rubans ; une valeur CV du ruban peigné et étiré ultérieurement (3) ; des valeurs CV des rubans peignés individuels fournies à l'unité d'étirage de la peigneuse ; un niveau de remplissage de bobine ; un état déroulé de chaque bobine de ruban insérée (2) ; un niveau de remplissage d'un espace de distribution de la peigneuse devant être occupé par une bobine de ruban ; une pression d'aspiration dans la peigneuse ou au niveau de ses têtes de peignage ; des défauts au niveau d'une tête de peignage particulière ; la rupture d'un ruban ou un ruban manquant au niveau des têtes de peignage et/ou au niveau de l'unité d'étirage de la peigneuse ; l'état dans un canal d'aspiration (9) de la peigneuse ; l'état d'utilisation et/ou la présence ou le résultat d'un processus de démarrage de filage de la peigneuse.
