Definitions
- the invention relates to a device for metering and / or leveling a liquid applied to a running surface medium to medium, wherein the surface for direct application of the medium, a paper, cardboard or other fibrous web and indirect application, the surface of a transfer element, for example a Application roller is which transfers the application medium to the surface of the fibrous web.
- the device comprises a holding body for receiving a doctor element and a pressure element, wherein the holding body is employed against the running surface and the pressure element presses the doctor element at its head against the running surface for the purpose of metering and / or leveling of the applied medium.
- the device further comprises a compressible and thus a hub exporting clamping hose, which presses the squeegee element at its foot against a support strip of the holding body while pressurizing and thereby clamps and releases the squeegee element in pressure release.
- a doctor blade or a doctor blade attached to a blade can form the doctor element and thus, as already explained above, this blade can be clamped into the doctor blade holder with the clamping hose.
- the clamping tube is inserted in a groove.
- the groove itself is either incorporated directly into the doctor blade holder or there is a bar, which in turn is firmly connected to the doctor blade holder and in this bar, the groove is recessed.
- a disadvantage of these embodiments is that on the one hand, the doctor blade holder thereby has a relatively complicated shape, which is therefore only consuming to produce and on the other is disadvantageous that the clamping hose must remain in the cleaning of the device in the doctor blade holder. Otherwise, all adjacent device components would have to be removed individually, which means a huge amount of time and thus downtime or production failure.
- the stroke of the clamping tube is chosen to be large.
- the groove must be dimensioned correspondingly large, whereby this is better accessible for service and cleaning purposes, but for the doctor blade or the doctor blade is poorly guided when pulling into the device.
- the blade is due to the larger space available at its footboard at an angle and can thus damage the terminal tube by cuts or the like with his foot, so that its function is no longer fair.
- the invention is therefore based on the object to provide an improved apparatus for metering and / or leveling, with which the disadvantages of the prior art can be avoided.
- the invention provides that an additional retaining strip for receiving the clamping tube is arranged.
- the retaining strip is received in a groove of the holding body and arranged parallel to the support strip.
- the retaining strip is attached or detachably arranged in such a way that, together with the clamping tube inserted in it, it can be easily removed from the device, cleaned or exchanged and reinserted.
- a hose change much faster and easier than previously possible and only takes about 2min.
- the retaining strip is provided to the support strip or to the clamped doctor element, with projections which protrude beyond the miniimetric stroke of the inserted in the groove of the retaining strip clamping tube.
- squeegee element in the context of the invention is intended to mean a very thin and sharp-edged doctor blade, but also such a flexible blade element, on which a squeegee rod mounted in a squeegee bed is placed.
- a doctor blade but also a metering rod whose doctor bed has a molded skirting board and the foot part is clamped in the doctor blade holder to be understood.
- An advantage of the invention is to be considered that the retaining strip including the pressurizable or compressed air compressed hose in a simple manner completely by hand from the holding body laterally or upwardly pulled out or can be inserted. It is understood that when removing or inserting the clamping hose is vented. - A -
- the cleaning effort can be reduced if the retaining strip made of plastic or at least partially coated with a dirt-repellent material, such as Teflon.
- a retaining strip made of plastic is lightweight and therefore particularly easy to handle.
- An expedient solution may be that the retaining strip is held in the holder body via an inflatable tensioning tube likewise embedded in it.
- connection with the holding body can also be made via a positive connection, for example by hooking, pinching or insertion, beispielseise training according to the principle groove / spring.
- the removal from or separation from the holding body is thereby very simple.
- the retaining strip can be made of a flexible or a rigid material.
- a further advantageous solution is that the clamping hose has only a small stroke or stroke. As a result, the space required is smaller. Also, the hose itself is less unstable with a smaller stroke, but also the doctor element or the blade can be performed better in the holder.
- Figure 1 a device according to the invention shown in section in section for dosing and / or leveling with inventive retaining strip and clamped doctor element
- Figure 2 the device acc. Fig.1 with pressure-relieved clamping hose
- FIG. 3 the device according to FIG. Figure 1 with removed retaining strip
- Figure 4 a first variant of the arrangement of the retaining strip
- Figure 5 a second variant of the arrangement of the retaining strip
- All components of the device 1 shown in section for metering and / or leveling a liquid to pasty medium M applied to a running surface 2 extend over the full width of the device, which in turn corresponds at least to the web width of the fibrous web to be treated.
- the running surface 2 is the direct application of the medium, such as coating color, glue, starch, a paper, cardboard or other fibrous web and indirect application, the surface of a transfer element, such as an applicator roll, wherein the transfer element the application medium to the surface of the fibrous web transfers.
- the medium such as coating color, glue, starch, a paper, cardboard or other fibrous web
- a transfer element such as an applicator roll
- the device 1 shown in Figure 1 has a holding body 3 (also as Squeegee bar or support body markable).
- This holding body 3 serves to receive a squeegee element 4 and a pressing element 5, wherein the holding body 3 is employed against the running in the direction L surface 2.
- the pressure element 5 is a hose acted upon with compressed air, which presses the doctor element 4 against the running surface 2 at its head part 4.1 for the purpose of metering and / or leveling of the previously applied medium M.
- the size of the contact pressure in the direction of arrow F of the doctor element 4 is selected.
- a doctor element 4 a flexible blade is shown in the example, the blade tip is pressed against the running surface 2. is.
- the device 1 further comprises a pressurizable and thus a hub exporting second hose, namely a clamping hose 7, which presses in the inflated state, so under pressure the doctor element 4 at its foot 4.2 against a support bar 8 or stop of the holding body 3. As a result, the doctor element 4 or the blade is clamped. When pressure is released, the doctor element 4 is released and can be removed or replaced.
- an additional retaining strip 9 is embedded in the holding body 3.
- the retaining strip 9 is inserted into a groove 10 and easily pulled out of this. As shown in Figure 2, after pulling out the retaining strip 9 enough space for cleaning purposes of the doctor blade holder and the groove 10 is available.
- the retaining strip itself takes in a trapezoidally shaped groove 11 (instead of previously the holding body 3 and the doctor bar) the clamping tube 7, as can be seen in Figure 1 and 3.
- the retaining strip 9 is arranged parallel or behind the support strip 8 so that in the inflated state of the located in the retaining strip 9 Clamping hose 7 ( Figure 1), the doctor element 4 clamped in the holding body.
- the clamping tube 7 is not damaged when pulling into the device 1 or pulling the doctor element 4 from the device 1 of the blade bottom 4.3, the retaining strip 9, starting from its groove 11 on both sides, the doctor element or blade 4 and the support bar 8 out pointing projections 12.
- These projections, but at least the lower projection 12 projects beyond the minimum stroke w of the clamping hose 7 by a distance a (about 1.5 mm). This also ensures a small gap s (about 3 mm) to the support strip 8. This ensures that a new blade 4 is better guided when pulling into the device or or a worn or damaged blade 4 when pulling out of the device. It is advantageous that this blade 4 abuts at least on this lower projection 12, instead of as previously contact the terminal tube 7 and damage.
- the blade 4 therefore takes in unimpaired clamping hose 7 - that is, when pulling or pulling them out (see Figure 3) a little oblique and almost vertical position, as shown in Figure 3 with dash-dotted line.
- a commercially available nose tube consisting of rubber, or rubber-reinforced material, or silicone or natural rubber or the like is shown. But it could also be a commercially available profile hose (such as the Anpressschlauch 5) or a commercially available round hose (as the tension hose 13) are used.
- the retaining strip 9 with a tensioning tube 13 or by a positive connection 14 (see Figure 5), for example by Ein technicallyeile, clips, or sliding elements such as a tongue and groove connection and the like.
- a positive connection 14 for example by Ein technicallyeile, clips, or sliding elements such as a tongue and groove connection and the like.
- On the holding body 3 detachably can be attached.
- These connections shown are easily solvable and thus also allow a quick replaceability of the retaining strip 3 with embedded clamping tube. 7 REFERENCE CHARACTERS
