Definitions

  • the invention relates to a squeegee device for dosing and / or leveling a liquid to pasty medium applied to a running surface, wherein the substrate is a running paper, board or other fibrous web for direct application and a transfer element which applies the application medium to indirect application the fibrous web transfers.
  • the doctor device has a support arranged on a support beam for receiving a metering and / or leveling doctor blade element.
  • Such squeegee devices find use in connection with commissioned work, which as I said serve the direct or indirect order.
  • the liquid or pasty medium to be applied is applied to the fibrous web, for example via a pressure chamber with the aid of a squeegee element designed as a doctor bar, a squeegee blade or a doctor blade.
  • doctoring devices for use in Enddosiervorraumen are known, with which a previously applied to the fibrous web layer of liquid or pasty medium is completely metered to a predetermined amount.
  • the finished metering is also carried out by means of one of the above-mentioned doctor elements. But the squeegee device can only serve to even out, so to equalize the previously applied in the desired amount of medium.
  • a squeegee device is known with a retaining strip for receiving a doctor blade, wherein the retaining strip in the immediate clamping region of the blade and / or in an adjacent region is flexible in the direction transverse to the blade, but relatively rigid in the direction of the blade width, to the least possible deformation to ensure the blade over its entire width.
  • the foot portion of the retaining strip which serves for fixing to a mounting base, in turn, is rigid.
  • the retaining strip usually comprises a plurality of individual parts, which together form an integrated unit, which are arranged separately on the actual support beam of the doctor device on this.
  • a squeegee device with a retaining strip and a doctor element attached thereto, which can be attached via mating bearing surfaces to a support beam or inserted into this.
  • a device is provided, with which a holding force can be applied, which attracts the holding bar to the support beam or sucks when it is attached to the support beams over the contact surfaces or inserted into this.
  • the device is designed such that the holding force can be switched off and switched on again.
  • a squeegee device which is provided with a seat for serving as a doctor blade element or associated leaf spring, which is clamped in its remote from the doctor blade of the doctor blade area by a clamping element which presses the leaf spring against a stop.
  • a chute parallel to the chisel edge is provided on the seat of the leaf spring, along which chute a series of vibration pulse generators are arranged, which makes it possible to clean the blade seat.
  • the invention has the object of developing a squeegee device that is simple in construction and provides for cleaning or maintenance optimal accessibility of all functional parts and can be disassembled and quickly reassemble.
  • a squeegee device which has a holder with a first, fixed and a second, movable, and bearing on sliding surfaces, stop bar.
  • the movable stop bar from the fixed stop bar to the outside (in the direction of the running surface) is displaceable.
  • the doctor element is clamped between fixed and movable stop bar.
  • the holder for receiving the doctor element eg a machine-wide doctor blade or a rotatable doctor rod accommodated on a blade-shaped support element in a doctor bed
  • further functional units are independent of one another arranged a support beam.
  • the first or fixed and the second or the movable stop bar of the holder under force to fix the doctor element, so that it, for example, in the operating state, the coated on a fibrous web coating composition and / or leveled.
  • the holder may be configured such that the fixed stop bar is arranged lying inside and connected to the support beam. Over its longitudinal extent, this stop bar can be traversed over the entire width of an applicator device with more or fewer recesses and bushings.
  • the movable stop bar has for maintenance breakthroughs and is openable in the direction of the current surface to be coated or a counter-roller, that it releases the doctor element in the open state on the one hand and on the other hand provides sufficient space for cleaning the support elements.
  • the maintenance condition - that is, when the holder is open - a free flow of colorant and cleaning agent is ensured by the, for example, lateral openings, such as drainage holes or slots.
  • An essential advantage of the solution according to the invention is therefore the optimum accessibility for cleaning the doctor blade holder. All functional parts of the squeegee device and the internal parts, such as hoses and moving parts are directly visible. Also, in the maintenance state, a free color sequence with the holder open - as already explained above- secured.
  • the doctor device according to the invention has a simplified structure, which can also disassemble quickly and reassemble. In addition, a compensation of different thermal expansion takes place, since the doctor blade holder itself and an existing for the contact pressure of the doctor element above the fixed stop bar pressure bar are not rigidly connected. As a result, at least one of the strips can expand freely.
  • sliding surfaces may be formed on the common contact surfaces of the stop bar or the supporting beam, which constitute a linear guide.
  • the linear guide is designed in the tolerances so that no harmful amounts of coating or other impurities can reach the bearing surfaces in contact with each other.
  • the movable stop bar can expand accordingly under thermal stress.
  • the tolerances of the linear guide ensure a highly accurate, precise recording and clamping of the doctor element.
  • the tolerances are in the range 0 to 1 mm, preferably 0 to 0.4 mm.
  • sliding surfaces are suitable, which consist of bearing metal or plastic, which have a low coefficient of friction and are primarily used lubricant-free.
  • the movable stop bar may be formed with three legs surrounding the fixed stop bar U-shaped, wherein the first (vertical) leg represents the actual movable stop bar and clamps the doctor element to the fixed stop bar in the closed state of the holder.
  • the second (vertical) leg is disposed in the holder inside and is acted upon by the holding force for the doctor element and the third (horizontal) leg connects the first and second legs rigidly together.
  • the third leg which corresponds in U-shaped design as I said, the horizontal part, be linearly passed through recesses in the lower part of the fixed stop bar and are in contact with the top of the support beam and is slidably mounted. A force acting on the second leg is thus transmitted via the connecting third leg on the first leg, there to hold the doctor element accordingly.
  • An equally advantageous variant provides that for the movement of the stop bar and for generating the holding force, two pressure hoses supported within the doctor device are arranged on both side surfaces of the second leg.
  • the first pressure hose which applies the closing force for fixing the doctor element, can be supported against a side face of the (fixed) stop bar rigidly connected to the support beam.
  • the second pressure hose which releases the doctor element for a blade change or maintenance work, can be supported against the side surface of a further support and retaining strip, which is usually also rigidly connected to the support beam.
  • either the first or the second pressure hose can be subjected to compressed air.
  • the holding force that presses the doctor element against the fixed stop bar in the operating state is determined by the pressurization of the pressure hose, which is supported against the rear side surface of the stop bar.
  • hydraulic or pneumatic cylinders may advantageously be arranged for moving the slide bar and for generating the holding force.
  • Such devices are suitable both for linearly displaceable and for pivotable versions of the movable stop bar for fixing the doctor element. Hydraulic or pneumatic cylinders offer appropriate design freedom in the structural design of the doctor device.
  • a pressure bar can over the holder be arranged for the doctor element for acting with an additional force, wherein the pressure bar and the holder are not rigidly connected together.
  • An example used coating blade is pressed by the force generated by a pressing force on the pressure bar, for example, to a counter-roller to adjust the layer or line thickness when applying paint on a fibrous web.
  • the non-rigidly interconnected pressure bar and the bracket can each extend independently of each other under thermal stress.
  • the pressure bar can be segmented.
  • the force over the entire length of the doctor element zonar and free of thermal stresses can be controlled accordingly.
  • the outer contour of the holder and / or the pressure bar can be sealed without play by at least one removable cover plate against contamination.
  • a cladding or encapsulation of the doctor device prevents in particular the deposition of hardly removable residues of the application medium used.
  • the at least one cover plate can be quickly removed and replaced by easily detachable connections. Removing the cover provides optimal accessibility to all internal parts, such as hoses and moving parts.
  • An expedient embodiment of the cover plate may consist in that it is made of a flexible spring steel. When installed, a defined force is exerted on the pressure bar by a bias of the spring steel. The bias is generated by fastening screws, which are preferably in a row in the middle of the cover, i. are arranged in the Federblechmitte.
  • the thickness of the cover or the cover plate or the spring plate should be 0.2 to 8 mm, preferably 0.5 to 4mm.
  • Fig. 1 shows a squeegee device 1 of a direct application of a coating machine, in which a doctor element 3 is employed in the form of a machine-width blade against a counter-roller 15.
  • the squeegee element 3 rakelt here or leveled here applied in excess application medium to the desired layer thickness (coating weight in g / m 2 ) on a counter roll 15 at least on a portion of its circumference wraparound running paper, cardboard or other fibrous web 16.
  • Das stripped application medium is forwarded via a paint return 14 for further use.
  • the doctor element 3 is fixed in a holder 2.
  • the holder 2 comprises a fixed stop bar 5 and a movable stop bar 6.
  • the stop bar 5 is optionally removable, for example via retaining elements, arranged on a support beam 4.
  • the stop bar 5 assumes an inboard position.
  • the stop bar 6 is displaceably positioned away from the inner stop bar 5 by a linear guide.
  • Fig. 1 is the slide-bearing linear guide, consisting of a third leg 63 of the overall U-shaped stop bar 6, formed with corresponding sliding surfaces 7.
  • a pressure bar 10 is arranged, with which the doctor element 3 can be acted upon with an additional force. The force is transmitted via a lifting rod 11 of the externally arranged lifting device 12 to the pressure bar 10.
  • the pressure bar 10 and the holder 2 are not rigidly connected. Not shown in the figures is the extending into the image depth segmentation of the pressure bar 10th
  • the movable stop bar 6 is a total of three legs 61, 62, 63 constructed, which surround the fixed stop bar 5 U-shaped.
  • the first leg 61 forms the actual stop, which fixes the doctor element 3 from the outside.
  • the vertical leg 61 is arranged outside in the direction of the counter-roller 15 and holds the doctor element 3 by pressing against the fixed stop bar 5.
  • To generate the holding force and to release two are within the squeegee device 1 supporting pressure hoses 81 and 82 at both Side surfaces of the second vertical leg 62 are arranged, which can be acted upon in each case with compressed air.
  • the first pressure hose 81 is used for fixing, the second pressure hose 82 for releasing the clamping action.
  • the stop bar 6 with its three legs 61, 62 and 63 may be integrally formed, but also a two-part design is conceivable. In the latter, so two-part variant, the bar 6 would consist of the second vertical leg 62 and an angular component in which the first and third leg 61 and 63 form this angular common component.
  • Fig. 2 is the squeegee device 1 for Maintenance work away from the counter-roller 15, whereby the entire counter-roller 15 facing the front is accessible. From there, in particular, the doctor element 3 and the parts of the holder 2 are freely accessible.
  • the Fig. 3 also shows as in FIG. 2
  • a removable cover plate 13 which preferably consists of a prestressed, flexible spring plate and which is arranged above the pressure bar 10
  • the doctor device 1 is freely accessible after removing the plate 13 from the top.
  • This flat design can also be a better quality control with regard to the detection and elimination of unwanted squeegee strip done because you now have access and insight up to the doctor blade or the blade tip.
  • the surface 13a of the cover plate 13 is formed so that it is either insensitive to dirt or easily cleaned.
  • this surface 13a may either be cold-rolled or polished or ground. However, it may also be coated with an anti-adhesive medium, such as PTFE (Teflon), from which any beads will bead off or are easier to remove.
  • PTFE Teflon
  • An additional or alternate cooling, e.g. Incorporated cooling channels also prevent the adhesion of dirt.
  • the third leg 63 of the slide bar 6 apertures 90, such as holes, slots, slots, so that the application medium and the cleaning water can flow freely during maintenance.
