Definitions

  • the invention relates to a machine for applying a liquid or pasty application medium by means of at least one commissioned work on the Surface of a running material web, in particular made of paper or Carton, wherein the commissioned work the order medium from a Dispensing opening arrangement, in particular slot nozzle, directly or under mediation of at least one guide surface in the form of a Gravity influence and / or under the influence of further forces towards a running background of moving curtain or veil, where with direct order the running underground the surface of the Material web is and in the case of indirect order the running underground Surface of a transmission element, preferably one Transfer roller, which is the application medium then to the Surface of the material web transfers, with the machine in assignment to the commissioned work or a discharge opening arrangement having Dispensing part of the commissioned work a medium catcher, if necessary collecting tray or gutter, to catch from the Dispensing opening arrangement dispensed order medium in Business interruption phases.
  • Such machines are known in many forms.
  • conventional is the commissioned work or the discharge opening arrangement having Dispensing part stationary in operation.
  • the at short-term Business interruption, e.g. a web break, to catch the Application medium serving catcher is between a collection position, in he or she catches the order medium curtain or veil, and one Adjustable order position, in which he laterally or in the direction of the Material web is arranged next to the commissioned work or the delivery part, such that the dispensed from the discharge opening arrangement Medium curtain or medium curtain unhindered to the running Underground meets.
  • the catcher In addition to exceptional operating conditions, such as web break, The catcher also comes when starting up and shutting down the machine used to start in the initial phase or in the final phase at shutdown, temporarily from the discharge port assembly collected and dissipate discharged application medium. It will be in This connection, for example, to DE 197 35 980 A1, DE 198 23 686 A1, DE 199 03 559 A1 and US 5,773,093.
  • the conventional medium catcher often in the form of a gutter is executed and the captured application medium in the transverse direction to Run direction dissipates the material web, conventionally must be relatively compact be executed, on the one hand, in view of the fact that the curtain is not a has such high height, so the discharge opening arrangement is not too high above the current underground, as well as on the other hand in the With regard to a not too large inertia, in the adjustment of the Catcher could be a hindrance or a problem. It follows the problem that with highly viscous media and / or very broad Machines a proper discharge of the collected medium difficult or even impossible to guarantee, or at most only at the cost of a too high curtain height.
  • the object of the invention is the machine so educate that the drainage of trapped by the interceptor, highly viscous coating medium and / or of these through a very wide material web captured order medium can be ensured can.
  • the commissioned work or the dispensing part in the machine during operation is adjustable between a collection position in which the medium catcher from the Dispensing opening arrangement dispensed order medium, and an order position in which from the dispensing opening arrangement discharged application medium hits the running surface.
  • the medium catcher itself can, at least in the normal continuous operation of the machine, be positionally stable. This will be one "Spillover" of the captured application medium due to a Adjustment of the medium catcher reliably avoided. Furthermore, the plays Mass inertia of the interceptor no longer matters. They are larger overall Medium catcher, if necessary gutters and / or discharge chutes, possible, before all in connection with an at least partial removal of the Application medium in the direction of the web or against the Direction of the material web to a fluid drain or to a in Transverse to the material web running medium trough.
  • the medium catcher on certain occasions is wegphal, so far not completely stationary. This can For example, in the case of Bahnetzmentss (threading), for example after a demolition of the railway be the case, in which the machine is also in in a certain sense "running". It is therefore in the above of "normal running operation" of the machine the speech in which the Medium catcher is positionally fixed according to a design option.
  • the catching position can be behind in the running direction of the running underground the order position so that a point of the current underground, especially the material web, first the order position and then the Catching position happens.
  • This embodiment is above all, but not exclusively, then advantageous if the material web in the area of Fall arrest position or / and horizontally or in the area of the order position Running direction of the web is sloping.
  • Another possibility is that the catching position in the direction of the running underground in front of the order position, leaving a post of the running underground, especially the material web, first the Trapping position and then the order position happens.
  • This embodiment is particularly advantageous (but not exclusive) if the Material web in the area of the collecting position and / or in the area of Application position rising horizontally or in the running direction of the material web runs.
  • the commissioned work or the Dispensing part in the collection position above the medium catcher is arranged, and that at least during operation of the machine Medium catcher over a portion of the moving web is arranged. It can be provided that below the Medium catcher a web deflection for deflecting the material web by at least one deflection angle and / or a Job preparation facility for the preparation of the contract of the Application medium is arranged on the surface of the material web.
  • the Web deflection or / and the job pretreatment device can with be integrated with the medium catcher to a unit.
  • the addressed job pretreatment is, for example, to a so-called Aircut or air boundary layer scraper or Heilgrenz Anlagenabsauger or the like, which is one of the Material web entrained air boundary layer weakens or removes to improve the order result.
  • a preferred Embodiment is characterized in that the material web in Area of the catching position and in the area of the order position in Running direction sloping. This embodiment is particularly then advantageous if the catching position in the running direction of the current Background behind the order position, because then based on a Given curtain height at the order position comparatively much Space to be provided in the height direction for the medium catcher can.
  • Another preferred embodiment is characterized in that the material web in the area of the collecting position and in the area of Order position in the running direction rising. This embodiment is especially advantageous when the catching position in Running direction of the current underground lies before the order position. It can then turn to a given curtain height at the Order position comparatively much space in height direction for the Medium catcher be provided.
  • the medium catcher be designed for this is the trapped application medium in the direction of the web or against the direction of the web to a fluid drain or to a medium trough running transversely to the material web dissipate.
  • the invention further provides a method for operating a machine according to the invention ready.
  • the commissioned work or the delivery part is adjusted by the collection position in which the medium catcher from the Dispensing opening arrangement dispensed order medium, in the Order position, in the dispensed from the dispensing opening arrangement Order medium meets the running underground or / and that to Ending or interrupting the order the commissioned work or the Dispensing part from the order position (back again) to the collection position is adjusted.
  • Fig. 1 shows schematically a curtain applicator 10 in one Coating machine for direct curtain application on a material web 12 is made of paper or cardboard.
  • the over a pulleys 14 and 16 comprehensive guide arrangement guided material web 12 runs below a curtain applicator head 18 of the commissioned work.
  • the curtain order header has in the usual way one in the transverse direction to the direction the material web extending distribution chamber 20 and one in the same Direction extending slot 22 on which the curtain or veil 24 from application medium, in particular coating color dispenses.
  • the curtain or Veil 24 hits a horizontally extending portion 12 'of Material web 12.
  • Job pre-treatment device for example a so-called Aircut, Air boundary layer scraper or Heilgrenz Anlagenabsaugung upstream be denoted by 28 and in the region of the guide roller 14 on the Material web 12 acts.
  • the movably arranged leads Gutter the collected application medium in the transverse direction to Running direction of the web from.
  • This requires at high viscosity Order media or / and large web widths due to the Discharge required gradients of the gutter in the transverse direction to Direction of the material web a corresponding space requirement in Height direction, resulting in a correspondingly high, may not desired arrangement of the application head 18 above the Material web section 12 'results.
  • the Medium catcher 26 a stationarily arranged and with the Job pretreatment device 28a integrated into a unit.
  • the curtain applicator head 18a may be between one shown in FIG solid lines shown in the curtain, the curtain of Medium catcher 26a is caught, and dashed in Fig. 2 illustrated order position mechanically adjustable, in which the application head 18a on a rising in the direction of the web 12 Material web section 12 'applies.
  • the medium catcher as stationary, as comparatively large Drip tray or designed as a comparatively large collection container be. Due to the rising in the direction of the course of Material web section 12 "in combination with the adjustability of Application head 18a between the collection position and the order position, As shown in Fig. 2, for the medium catcher particularly large amount of space be provided in height direction, without thereby a large curtain height, so a large distance between the outlet of Slot nozzle 22 and the web portion 12 "in the order position the application head 18a is conditional.
  • the curtain height referred to the surface of the web portion 12 is in the Catching position greater than in the order item, and the difference between these heights stands as additional space in the height direction for the medium catcher available.
  • FIG. 3 differs from the Embodiment of Fig. 2 by another material web guide.
  • the media catcher 36b Apart from the direction of the web, is the media catcher 36b relative to the web substantially the same positioned and formed as in the case of FIG. 2. That in the Auffangposition of the application head 18b trapped application medium is accordingly after collecting first in the running direction of the material web dissipated, as symbolized by the arrow M.
  • the Mediumaufflinder integrated job pretreatment device 28a is now a job pretreatment device 28b in the direction behind the Order position arranged so that the material web before the order there pretreatment, such as air boundary layer weakening or removal, is subjected.
