Definitions

  • doctor device for various uses, such as e.g. coating application or removal of substances on / from flat surfaces, e.g. Material webs, transport lines, conveyor belts or rollers and / or for cleaning and / or drying smooth, rough or grained surfaces such as e.g.
  • squeegee which consists of at least one preferably one-piece squeegee holding and pressure bar, a squeegee bar, a part designed as a working element or a part inserted into the squeegee bar at a contact point, including at least one between the two bars Doctor blade and pressure bar and the doctor bar or the working element - arranged elastic element presses against at least one work surface, for example can be a template or a screen cylinder.
  • doctor blade work parts are attached to doctor blade holding parts and that these doctor blade holding parts are attached to the respective doctor blade working machine attached and in any case held so that the forces required for squeegee pressure are introduced via these holding parts and transferred to the squeegee working part.
  • Squeegee devices or application devices which rest loosely movably on the application surface, including those which are loaded with gravity or weight or with mechanical means, and especially those which are pressed magnetically.
  • Squeegees that are loose or attached to holders that are magnetically pressed are known in numerous variants, primarily those squeegees, especially all squeegees that are made of magnetizable material, but also those that are connected to parts made of magnetizable material and thereby pressed or additionally pressed thereby are known.
  • a general disadvantage inherent in magnetic squeegee technology is that each magnetizable material can only be magnetized up to a certain degree of saturation and that in practice considerable distances between the pole faces of the magnetic device and the squeegees or parts of squeegee devices to be magnetized increase are bridged. Since these two disadvantages have an additive effect, the designer and the user of such devices often reach the limits of the possible applications. In practical terms, this means that with magnetic doctor devices, in particular magnetic roller doctor blades of small diameter, it is not possible to achieve sufficiently high contact forces, so that their application, which would often be very necessary, has to be avoided.
  • the object of the invention thus presented is to eliminate the above-described disadvantages inherent in the prior art and to provide a versatile doctor blade or doctor blade device which works with great precision but is nevertheless very simple in construction and is easy to handle.
  • the squeegee or squeegee device consists of a squeegee holding and pressure bar and a squeegee bar which is formed or is a working element at the squeegee contact point and which is movable along its entire length in the vertical or approximately vertical direction to the work surface, touching the surface and preferably more as encompassing or engaging half of the cross-sectional circumference of the squeegee strip / the working element; into the groove-shaped recess of the squeegee holding and pressure bar, which makes this plug / slide connection possible, is in the area transmitting the squeegee pressure force between these two bars, extending over their longitudinal extent, a pressure-elastic, the pressure force equalizing and / or if necessary generating element, applied to both of them and, if necessary, also enclosing the squeegee in a U-shape and thus also touching the two side surfaces.
  • FIGS. 2 to 17 The squeegees and squeegee devices constructed in accordance with the invention and shown in FIGS. 2 to 17 were preceded by FIG. 1 taken from the prior art, which illustrates one of the efforts made up to now to increase the contact pressure of a magnetically pressed doctor roller relatively small in diameter: that of the The second roll placed on the work roll is intended to increase the contact pressure of the work roll; the holder required for this is designed as a second function as a height-adjustable stowage profile strip.
  • FIG. 2 shows an illustration of the essential facts of the invention or construction features of a doctor device 1 constructed according to the invention in an abstract representation: a doctor holder and pressure bar 2 with a U-shaped cross section, which is formed by a groove-shaped recess 3, with a groove-shaped recess 3 in this inserted pressure-elastic element 5, which is formed in this embodiment according to Figure 2 as a further profile strip with a U-shaped cross section and for the purpose of increasing the pressure elasticity may have incorporated a cavity 56.
  • the doctor profile strip or the actual doctor element 4 is in contact. This doctor element 4 is also held in the groove-shaped recess 33 of the elastic profile element 5.
  • the squeegee and pressure bar 2 is held between sliding elements 6 so that it can be moved.
  • the squeegee strip 4 touches in the work area an optionally flat or curved or rounded work surface 7 or material web 72 (work table or magnetic work table 71, counter roller, magnetic roller with magnet 71) resting thereon, which is not shown separately in the drawing.
  • the doctor pressure is - abstracted by a strong arrow 203 - caused either by mechanical means (not shown) or by magnetic attraction, for which it is provided according to the invention to manufacture the doctor and pressure bar 2 (at least partially) from magnetic material. According to the invention, it is also provided that several types of doctor pressure generation can be combined with one another.
  • the elements generating the magnetic force can be connected to the doctor blade holding and pressure bar 2 and that in this case the work table or the work roll consists of magnetizable material.
  • the small double arrow inserted in the arrow 203 representing the contact pressure indicates the sliding mobility of the strips or the elements 2 and 4 in the direction of the vertical axis on the work surface or their relative displaceability relative to one another, which is one of the essential features of the invention.
  • the other figures show pressure-elastic bodies in different design variants, which, however, do not touch the doctor element 4 on three surfaces as shown in FIG. 2 but only touch the side or surface of the doctor strip 4 opposite the doctor contact area which the squeegee pressure is introduced into the squeegee.
  • the squeegee element which is a roller in some exemplary embodiments, is movable in the recess 3 of the squeegee holding and pressure bar held, which can also be held pivotably.
  • FIG. 3 to 5 show three further exemplary embodiments of doctor devices 1 constructed according to the invention and their essential structural parts.

  • FIG. 5 corresponds to a combination of FIGS. 3 and 4, it being shown in dashed lines that the bar 2, if a large doctor pressure force is required, for which the magnetizable mass of the bar 2 is too low, depending on Requirement enlarged as a bar 21 can be formed.
  • the intermediate bar 42 is drawn in broken lines because such a bar could be omitted in the particular exemplary embodiment of FIG. 5 if the working element 43 is used in a rotationally fixed design.
  • Fig. 6 corresponds essentially to Fig. 3, differently to the working element 45 is formed at an acute angle and the doctor pressure is caused by the weight of the bar 2 and additional weights 22, which are only shown symbolically. Instead of one element 5, two elements 51 and 52 having the same function are used.
  • a support beam 61 e.g. with screw connections 62, fixed in place, similar to that shown in FIG. 4.
  • a magnetic force or a pressure force generated by means of a liquid or gaseous medium
  • the vertical sliding ability of the bar 2 is only effective when the magnetic force is switched on.
  • the combination of two different contact forces can bring about a correspondingly greater total contact force by adding together.
  • a basic setting of the contact pressure is carried out, which is correctly dimensioned for the slowest possible working speed and can then, with the second contact force component, increase the contact pressure required when the speed increases, e.g. can be carried out automatically by electronic control - the contact pressure can also be reduced if the speed is reduced.
  • a bar 23 is held on a joint 124 so as to be capable of rotating torsion, an elastic doctor blade 47 is inserted into the bar 46.
  • the bar 24 is circular cylindrical over its entire length, but it would suffice if only those places were circular cylindrical or rounded where the sliding holding parts 64 abut.
  • the bar 4 is formed with an acute-angled working element 45, the recess 3 is arranged asymmetrically in the bar 24 and is provided in the opening area with projections 31 which prevent the bar 4 from undesirably sliding out when the bar 24 is lifted off.
  • An arm 25 is fastened to the bar 24, by means of which the pivoting mobility is limited by means of adjustable stops 26.
  • Fig. 10 is similar to the embodiment of Fig. 9, but is torn off Drawn arm 27 part of an auxiliary device, on which the bar 24 is rotatably fixed - possibly vertically movable, possibly oscillating - is held.
  • a flexible and pressure-elastic working element 47 is inserted into the strip 46, the bending of which results from the movement of the template 73 in the direction of the arrow 74 and from the magnetic squeegee pressure.
  • a stowage profile bar 28, which can be pivoted and rotated about this bar, is plugged onto the bar 24, the pivoting movement of this bar 28 is actuated by a swivel device 29.
  • FIG. 11 shows a bar 2 with extension bars 201, by means of which the bar 2 is held on threaded spindles 202 in such a way that the bar 2 can be moved in height or its distance from the working surface 72 can be adjusted.
  • the strip 2 is pressed against a pressure-elastic element 53, which is not solid, but solid. Changing the distance of the bar 2 changes the contact pressure.
