Definitions

  • the invention relates to a stripping device with the features specified in the preamble of claim 1.
  • a device of this type is e.g. B. is known from US-A-3 158 498. Thereafter, it is a device for stripping excess coating slip from a running web coated with the coating slip, e.g. B. paper web.
  • the stripping is carried out by means of a doctor blade which has an elastic blade.
  • This squeegee can be made in two different forms: either it consists solely of the elastic blade. In this case, the blade is pressed against the web even with its free end. Or the doctor blade is composed of a blade and a roller doctor blade attached to the free end of the blade. In this case, the roller squeegee is pressed against the web. In both cases, the blade is more or less deformed when pressed against the web.
  • the purpose of such a stripping device is to achieve a layer thickness that is as uniform as possible when coating a material web with coating slip.
  • the layer thickness should be adjustable, for example by changing the force with which the squeegee is pressed onto the web.
  • the material web can run over a rotatable roller or over a fixed support device. Or the material web runs between two symmetrically arranged stripping devices if it has been coated on both sides at the same time beforehand.
  • doctor support beam can be pivoted about a first pivot axis which runs transversely to the direction of web travel as close as possible to the line of attack of the doctor on the web.
  • This pivotability is necessary in order to be able to vary the basic setting of the doctor blade, for the purpose of adaptation to different types of web, coating compositions or to different doctor blade designs.
  • the blade working angle already mentioned thus results from this basic setting and from the applied contact pressure.
  • the doctor blade support beam - seen in cross section - has an additional pivot axis (D) between the point of application of the doctor blade on the running web and the point of application of the support strip on the blade.
  • the support bar is arranged there on an extension of the blade clamping device. If the squeegee support beam is pivoted about this additional pivot axis, the contact pressure changes (while the blade is deformed), the blade working angle remaining constant.
  • this beneficial effect exists - when working alone with the blade, ie without a doctor blade, only as long as the blade is not or only slightly worn. Blade wear is unavoidable with all blade scrapers; A blade generally lasts between about 1 hour and 10 hours.
  • the device known from documents 1 to 3 thus has the disadvantage that after a certain wear of the blade, keeping the blade working angle constant when varying the contact pressure no longer succeeds to the desired extent. You are therefore forced to replace the worn blade with a new blade earlier than would be necessary.
  • Another Disadvantage of this known device consists in the following: If the blade is already worn to a certain degree, then - to increase the contact pressure by a certain amount - the doctor blade beam must be pivoted through a larger angle (about the additional pivot axis D mentioned) than with a new blade. In other words: the adjustment range of the contact pressure is too small in the case mentioned.
  • the doctor blade support beam is supported at both ends in an eccentric disc.
  • the axis of this bearing is the above-mentioned additional pivot axis (D).
  • Each of the eccentric discs is supported in a support.
  • the axis of this mounting is the first pivot axis mentioned at the outset, which is as close as possible to the line of attack of the doctor blade on the web.
  • the support strip is attached to the doctor beam, while an additional beam is provided as a clamping device for the blade, which is arranged displaceably in the blade support beam.
  • the plane of displacement and the plane determined by the unloaded blade form an acute angle.
  • the blade clamping device is not displaceable there along a plane, but can be pivoted about an additional axis.
  • the support bar (6) is arranged on an additional beam (8) which is pivotally attached to the doctor beam.
  • the contact pressure is varied there by pivoting the support bar and the associated change in shape of the blade. So that the blade working angle remains the same with such a variation of the contact pressure, the following measures are taken there:
  • the drive for the pivoting device of the doctor blade support beam can be actuated by means of a control device as a function of the change in shape of the blade, to such an extent that the blade working angle remains unchanged.
  • This construction can in principle meet the above requirement (keeping the blade working angle constant while varying the contact pressure). It is also sometimes disadvantageous that the subsequent pivoting of the doctor support beam to a change in shape of the blade takes place with a certain delay.
  • the adjustability of the doctor blade support indicated in feature f makes it possible to vary the pressure force of the doctor blade on the web.
  • the adjustment of the doctor beam is carried out without pivoting the support supports; that is, the position of the first pivot axis of the doctor beam, which coincides with the doctor line of attack as precisely as possible, remains stationary.
  • Another step necessary to achieve the object is the coupling of the pivot drive (for pivoting the doctor support beam about said first pivot axis) and the actuator (for adjusting the doctor support beam mentioned in feature f) for a correspondingly specified in feature g of claim 1 combined movement of the doctor blade support beam.
  • This coupling need not necessarily be mechanical (although it is preferred). Rather, an electrical coupling of two separate drive motors is also conceivable. The only thing that is decisive is that when the contact pressure (the doctor blade against the running web) varies, both drives are active together, so that the doctor blade support bar carries out a combined movement (triggered by the two drives).
  • the first pivot axis of the doctor blade support beam always remains stationary, regardless of the contact pressure that is set.
  • the advantage of the construction known from documents 1 to 3 is retained that the blade working angle can be changed, if necessary, for each set contact pressure (by pivoting the doctor support beam about the first pivot axis) without the contact force changing.
  • An essential feature of the construction known from documents 1 to 3 is that only one of the two possible pivoting movements of the doctor blade support beam can take place at the same time, namely either about the first pivot axis lying in the doctor blade line of attack or about the mentioned additional pivot axis D.
  • the movement which instead is provided according to the invention and is composed of two simultaneous individual movements, now makes it possible to change the speed ratio of the two individual movements, preferably as a function of the degree of wear of the blade (if working without a doctor blade). This makes it possible to use the advantage of keeping the blade working angle constant when varying the contact pressure not only in the new but also in the largely worn-out state of the blade. According to the applicant's knowledge, this extraordinarily favorable property has none of the numerous known constructions.
  • the invention offers a further advantage compared to documents 1 to 3: due to the feature f of claim 1 explained above, the adjustment range of the contact pressure is also quite large when the blade is already largely worn out.
  • the construction according to the invention has u. a. the advantages that neither the support bar nor the blade clamping device have to be designed to be movable relative to the doctor beam and that the blade working angle can be kept constant (when adjusting the contact pressure) with greater accuracy and without any time delay.
  • FIG. 1 shows a stripping device in an oblique view.
  • FIGS. 2a, 2b and 2c show the movement sequence of the doctor support beam when the contact pressure is adjusted in a schematic side view.
  • Figure 3 shows a drive scheme for the screw jacks.
  • FIG. 4 shows an enlarged detail from FIG. 1.
  • FIG. 5 shows a schematic side view of the detail shown in FIG. 4.
  • FIGS. 1 and 2a The essential individual parts of a stripping device according to the invention can be seen in FIGS. 1 and 2a.
  • Two support supports 20 are rigidly connected to one another by a connecting tube 21 and are mounted in bearing blocks 22 so as to be pivotable about a pivot axis X. In the operating position, the support supports 20 project approximately vertically upwards. At their upper ends they each have a bearing journal 2 or, more generally speaking, a pivot bearing 2.
  • a doctor beam 5 is supported therein, in a manner which will be described in detail later.
  • FIG. 2a a small piece of the jacket of a counter-roller is indicated by a line C, which is provided with hatching.
  • This roller is omitted in Fig. 1; it runs in the direction of arrow P (FIG. 2a) and, at an angle, runs from bottom to top a paper web which has been coated with a coating slip on its underside.
  • a squeegee e.g. B. an elastic blade 6, the excess coating slip is stripped from the paper web.
  • the point of attack of the blade on the paper web is as close as possible to the axis of the pivot bearing 2 (this axis is hereinafter referred to as the «first pivot axis A).
  • the support supports 20 rest when the device is ready for operation at a fixed stop 60 each.
  • the entire device can be pivoted about the axis X, in the case of FIG .
  • the blade 6 is - seen in the cross section of FIG. 2a - directly attached to the doctor beam with its lower end.
  • a clamping bar 8 can be provided, which is only indicated schematically in FIG. 2a.
  • a support bar 7 is also attached to the doctor blade support bar 5, which supports the blade 6 in the area between the clamping and the tip engaging the paper web.
  • the usual devices for fine adjustment of the support bar 7, which serve to even out the cross-section of the coating, are omitted.
  • a roller squeegee can be used in a known manner in the device described above, with the aid of a blade-like elastic holder, to the free end of which the roller squeegee is attached.
  • the doctor beam 5 each has a support arm 3 at both ends, which extends in the region of the first pivot axis A.
  • each of the support arms 3 has a pivot bearing or bearing journal 4. Its axis is arranged eccentrically to the first pivot axis A and is referred to below as the «second pivot axis Z.
  • the doctor beam 5 rests pivotably in a respective support element 11, which is preferably designed as an intermediate lever.
  • Each intermediate lever 11 is. in turn mounted in the adjacent support bracket 20 by means of the pivot bearing 2 already mentioned. The free end of each intermediate lever 11 is connected to the doctor beam 5 with the aid of a spindle lifting mechanism 10.
  • the doctor blade support beam itself is supported by a further spindle lifting mechanism 12 in a bearing block 13 which is fastened to the connecting tube 21 mentioned above.
  • the screw jack 12 forms the swivel drive for the doctor beam 5; d. H. by actuating the spindle lifting mechanism 12, the doctor beam 5 is pivoted together with the intermediate levers 11 about the first pivot axis A (see FIGS. 2b and 2c).
  • This allows, among other things, the basic setting of the angle between the blade and the paper web to be set. 2a, 2b and 2c, only the center lines of the spindle hoists 10 and 12 are shown.
  • the two intermediate levers 11 are pivoted about the first pivot axis A without the doctor beam 5.
  • the position of the second pivot axis Z is adjusted relative to the first pivot axis A (see FIGS. 2a and 2b).
  • this pivoting of the intermediate lever 11 has the consequence that the doctor blade support beam — viewed in cross section — is moved closer to the counter roller C together with the blade clamping and together with the support bar 7 or is removed from the latter.
  • the contact pressure of the blade 6 against the paper web is changed while the blade is deformed.
  • the two screw jacks 10 which are always connected in a rotationally fixed manner, can be coupled to the screw jack 12 by means of a clutch 36.
  • the pivoting movements shown in isolation in FIGS. 2a, 2b and 2c can be superimposed on one another. In other words: in reality the transition from the position according to FIG. 2a to the position according to FIG. 2c takes place immediately and not via the intermediate position, which is shown in FIG. 2b.
  • Fig. 2a the blade 6 is shown in the unloaded, undeformed state.
  • the contact pressure of the blade against the paper web is approximately zero.
  • the blade has an obliquely ground blade sweeping surface that runs exactly parallel to an imaginary tangent T, which is placed on the lateral surface C of the counter-roller in the first pivot axis A.
  • the blade 6 and the tangent T enclose the blade working angle k with one another. (In Fig. 2a it is only coincidental that the blade 6 extends parallel to the support supports 20. Of course, other starting positions are also possible.)
  • the bearing journal 4 of the intermediate lever 11, in which the squeegee support beam 5 hangs is arranged in such a way that the second pivot axis Z is close to that plane B which is determined by the unloaded blade 6.
  • the pivot axis Z is preferably arranged in the region of the back of the paper web, which abuts the counter roller C. It is best to ensure that the second pivot axis Z - in the unloaded state of the blade 6 - lies between said plane B and the tangent plane T. Then the second pivot axis Z - transversely to said plane B - by actuating the screw jacks 10.
  • the second pivot axis Z can also be arranged on the blade 6 in the vicinity of the line of attack of the support strip 7. In this case, the pivoting direction of the intermediate lever 11 must be reversed from the arrangement described above.
  • FIGS. 1 and 2a to 2c Another construction, which deviates even more from FIGS. 1 and 2a to 2c, could be designed as follows: Instead of the intermediate lever 11, a disk could be mounted on each support support in the pivot bearing 2, which carries the support arm 3 of the doctor beam 5 in a sliding guide. In this case, the sliding guide would have to make it possible for the doctor blade support bar 5, in a similar manner to that shown in FIGS. 2a and 2b, to be adjustable again transversely to the plane B mentioned, that is to say transversely to the direction of the extension of the blade 6 Drive device are provided, which in turn can be coupled to the swivel drive 12 via a coupling.
  • the spindle or threaded rod 12 engages in a nut 14. This has two journals 15, with which it rests in a bearing block 13 which is fastened to the above-mentioned connecting tube 21.
  • the spindle 12 is driven by means of an electric motor 30, shaft 31 and bevel gears 33 and 34 (with gear housing 32).
  • the spindle 12 can drive the input shaft 37 of a bevel gear distribution gear 39/41 via a clutch 36.
  • This has a gear housing 38 and two output shafts 40, which extend along the doctor beam 5.
  • a bevel gear angular gear 46, 47, 48 is arranged, which drives the spindle or threaded rod 10 via a universal joint 49.
  • the latter engages in a fork nut 23 which is articulated to the intermediate lever 11.
  • Bearing blocks 43, 44 are provided on the doctor beam 5.
  • the gear housing 46 is rigidly attached to the bearing block 44.
  • the housing 38 of the distribution gear 39/41 is pivotally mounted on the bearing blocks 43.
  • the spindle 12 is supported via the bevel gear 34 and an axial bearing 35 on the gear housing 38 and this via the bearing blocks 43 on the doctor support beam 5.
  • rotating the spindle 12 pivots the doctor support beam 5 about the axis A result.
  • the spindle 10 is supported on the universal joint 49 and on the thrust bearing 45, also on the gear housing 46 and the bearing block 44 on the doctor beam 5.
  • rotating the two spindles 10 (only one of these spindles is visible in FIG. 3) causes the intermediate levers 11 to pivot about the axis A. This is triggered when the clutch 36 is engaged by rotating the spindle 12.
  • FIG. 4 shows an important further embodiment of the invention, which is not shown in FIGS. 1 to 3, namely the variable articulation of the lifting spindle 10 on the intermediate lever 11.
  • the intermediate lever 11 has a rectangular recess 51 in the form of a sliding guide, in which a sliding block 50 is slidably arranged.
  • the fork nut 23 is connected in an articulated manner to this sliding block 50 (pivot pin 29).
  • a threaded spindle 24 is rotatably mounted, which engages in the sliding block 50 and can be rotated by means of a handwheel 25. With this device, it is possible to change the distance between the first pivot axis A and that of the axis of the pivot pin 29.
  • the positions 29a and 29b of the pivot pin 29 represent the two positions of the intermediate lever 11 in FIGS. 2a and 2b due to a stroke s of the spindle 10.
  • This pivoting of the intermediate lever 11 results in an adjustment of the doctor beam 5 transversely to the extent of the blade 6 (seen in cross section) by the adjustment path v.
  • the doctor blade support bar 5 is pivoted by the difference angle d.
  • the adjustment path v and the difference angle d are coordinated with one another in such a way that (as also stated above) the blade working angle k remains constant during the combined adjustment movement.
  • the dimensions a and b on the blade 6 must be taken into account, among other things.
  • a is the distance from the blade tip to the point of application of the support bar 7 and b is the distance thence to the blade chuck 8.
  • the ratio a / b can change due to wear of the blade tip or intentionally by moving the point of attack of the support bar 7 z. B. by exchanging a support bar for another.
  • Such a change in the ratio a / b requires a new adjustment of the size ratio d / v, for example by moving the pivot pin 29 from the position 29a to the position 29a '. If the same stroke s of the spindle 10 now takes place, the pivot pin 29 moves into the position 29b '. As a result, the adjustment path of the doctor blade support bar is increased to the value v '.
  • a control device can be provided which is connected to a measuring device for the coating thickness and which controls the motor 30 in such a way that the coating thickness remains between the respectively permissible limit values.
  • the control device can switch the motor 30 on and off at specific time intervals. But it is also possible that the control device constantly controls the speed of the motor when it is running continuously at a very low speed. In any case, the described process of gradually or continuously tracking the Rakeitragbalkens 5 runs until the blade is completely worn.
  • the following can now be accomplished in the above-described tracking process:
  • You can use the handwheel 25 to select the effective length of the intermediate lever 11 (ie the distance between the first pivot axis A and the axis of the pivot pin 29) such that the blade working angle k remains as constant as possible during the life of a blade.
  • the effective length of the intermediate lever 11 is set on the basis of the experience in the life of the blade used in each case.
  • An additional drive motor 30a is coupled to one of the shafts 40 (as shown in broken lines in FIG. 3).
  • this motor can drive the two spindles 10 in order to pivot the two intermediate levers 11 about axis A alone.
  • This in turn causes the doctor beam 5 to be tracked, but without simultaneously pivoting it about the axis A.
  • there is a gradual adjustment of the doctor beam similar to that shown in Figures 2a and 2b. In a rough approximation, this is a parallel displacement of the doctor support beam 5 in the direction of the counter-roller C.
  • the blade contact pressure is not increased. Rather, the purpose of this shifting is now to keep the blade contact force constant, taking into account the current blade wear.
  • the advantage of this type of tracking of the doctor blade support beam can be seen in the fact that the blade working angle k does not change. I.e. there are no special measures for keeping the blade working angle constant. In particular, the adjustability of the effective length of the intermediate lever 11 shown in FIGS. 4 and 5 is not required.
  • the possibility of driving the spindles 10 alone can be used for a completely different purpose: You can thereby move the doctor beam 5 so close towards the counter-roller C that the blade working angle becomes almost zero; ie the working angle of the blade is still considerably smaller than the angle k 'shown in FIG. 2b.
  • the operation of the stripping device in this state is the so-called curved driving style, also known as the “bent blade” driving style; see publication 7, FIG. 4.
  • the construction according to the invention makes it possible to set the blade contact pressure very sensitively in the “bent blade” mode of operation and to keep the very small blade working angle precisely constant. The method described above with reference to FIGS. 2a to 2c is used for this.
