Description

The invention relates to a separating element of a headbox of a machine for producing a fibrous web, in particular a paper, board or tissue web, with a separating element sheet and with a hinge element arranged at the upstream end.

Furthermore, the invention relates both to a method for producing a separating element of a headbox of a machine for producing a fibrous web, in particular a paper, board or tissue web, as well as its use.

Such a separating element in the form of a lamella is, for example, the two German Offenlegungsschriften DE 199 62 709 A1 and DE 196 52 981 A1 known.

The hinge element of the disclosed in the first publication separating element is, as shown at least in Figures 3, 4 and 12, worked from the "full", so machined from the separator sheet, preferably milled out.

Alternatively, the hinge element of the separating element of two separate and preferably mirror-image hinge halves and is placed on the preferably finished separator sheet, preferably glued, riveted or additionally stored in positive shots. This embodiment is shown for example in Figures 5, 6 or 11 of the first document.

Furthermore, as disclosed in the second document, the hinge element is arranged on a separate hinge support. The hinge carrier made of a metal or a plastic is then, as shown for example in Figures 5 and 6, positively or non-positively connected via a joint with the separator element sheet.

The known separating elements, which have at least one separating element sheet and a hinge element arranged at the upstream end, have relatively large recesses, for example in the range of 8 to 10 mm, between the separating elements and the. Due to the mechanically necessary execution of the hinge member carrying the hinge element and the realizable hinge diameter adjacent turbulence channels of the turbulence generator of the headbox. This results in coarse macro-turbulence, which may sometimes migrate along the respective separating element through the headbox nozzle and influence the material jet negatively and also uncontrollably. This can lead to larger and unacceptable disturbances and inhomogeneities in the fibrous web to be produced

Furthermore, the mentioned embodiments of the separating element are relatively complicated and thus expensive. In particular, the number of parts, the processing, the connection and the manufacturing process of the items in the cost reflected.

It is therefore an object of the invention to improve a separating element of the type mentioned in such a way that the return between the separating element and the adjacent turbulence channels of the turbulence generator of the headbox is significantly reduced. In addition, the production cost of the separating element, in particular in terms of cost and time, should be reduced.

Furthermore, both an efficient and a cost-effective method for producing the separating element according to the invention should be specified.

This object is achieved in a separating element of the aforementioned type according to the invention that the separator sheet is formed from a laminate comprising at least two layers and that the at least one base body comprehensive hinge between at least two [forming part of the hinge] layer layers of the laminate is embedded.

The object of the invention is completely solved in this way.

The separating element according to the invention has in comparison with the known separating elements of the prior art, a significantly reduced diameter of the hinge element and thus a markedly reduced return. The separating element according to the invention has a recess in the range of 4 to 5 mm, ie a value reduced by up to 60% in comparison with the prior art.

In addition, the separating element according to the invention has a reduced production cost, since, for example, only a small reworking of the outer contour is necessary. And the hinge element basically no longer requires machining, so that a high degree of manufacturing effort can be saved in comparison with the known separation elements of the prior art.

Also, the separator of the invention has improved properties, since a "rigid" separating element made of a fiber-reinforced plastic (GRP, CFRP, etc.) can be produced.

The individual layers of the laminate may have different structures. Thus, the layer layer of a simple lamella, for example a short lamella or a stubby lamella, may for example be formed from at least one simple fabric, but the layer layer has to fulfill the operational and technological requirements with regard to evenness and rigidity. On the other hand, the layer layer of a higher-quality lamella, for example a so-called high-tech lamella, can be produced by means of the rowing technology with the possible use of prepreg threads. The threads are for the production of the layer layer generally filed multiple times and precisely under a preferably selectable deflection angle. The layer layer of such a higher-quality lamella, of course, has to meet the operational and technological requirements with regard to evenness and rigidity.

The respective layer layer preferably has a layer thickness in the range from 0.3 to 3.0 mm, preferably from 0.4 to 2.0 mm. This allows an individual dimensional design of a separating element while ensuring further necessary properties.

In order for the separating element to have optimum properties for the particular application, the layer layers may consist of the same or different materials. For example, if the laminate is formed from at least three layer layers, the upper layer layer and the lower layer layer may preferably consist of identical or approximately the same materials.

In a preferred embodiment, it is also provided that the laminate is formed from at least three layer layers, wherein the at least one middle layer layer is arranged at least in the region facing away from the upstream end. Thus, fewer layers are present in the upstream region, which ultimately leads advantageously to a reduced diameter of the hinge element.

The main body of the hinge preferably has a circular, an oval, an elliptical or a polygonal cross-sectional shape. This provides the advantage of maximum flexibility in terms of hinge form. The polygonal cross-sectional shape can also include edged and triangular cross-sectional shapes in a manner obvious to the person skilled in the art. The respective cross-sectional shape and the resulting contour are usually also formed on the outer shape of the hinge.

Furthermore, the main body of the hinge is preferably made entirely of a metallic material, in particular stainless steel or titanium. Such a On the one hand, the material ensures the strength of the hinge required during operation, on the other hand it is ideal for such use, inter alia because of its chemical properties.

Furthermore, the main body of the hinge, which preferably consists of the same material as the layer layers of the laminate, is preferably formed from a solid material or a hollow material. These types of body allow many design options in terms of mechanical properties and weight.

The regions of the outer layer materials forming the hinge element preferably have specially adjusted resin properties, such as, for example, the friction in the hinge region or the wear resistance of the hinge. For example, the regions of the outer layer materials forming the hinge element can be provided with friction-reducing particles, such as, for example, graphite. The regions of the outer layer materials forming the hinge element can also be provided on the outside with at least one coating, such as a film or a coating, so that the friction in the hinge region can be minimized. Also, the use of microballoons, glass beads and the like in achieving the corresponding properties is possible.

The object of the invention is achieved in a method of the type mentioned in that the laminate comprising at least two layers in two grooved mold halves, which depict the preferably finished outer contour of the separating element, is pressed under pressure and temperature, wherein before pressing the laminate at least one Layer is introduced into a lower mold half, then the at least one base body comprehensive hinge in the groove is applied to the top of at least one introduced in the lower mold half layer and then at least one further layer layer is applied to the already introduced into the lower mold half layers , and finally the upper mold half on the last applied layer under pressure and Temperature is brought to preferably complete curing of the laminate between the two mold halves is brought.

The method according to the invention is therefore also characterized by a solution suitable for plastics with low notch effects and smooth transitions as well as the avoidance of layer injuries, for example severing of layer layers.

As resins melamine or phenolic resins known to those skilled in the art may be used. Also, a counter-pull can be used on the underside of the laminate, which reduces the effect of the bowl, as a bending of the finished material.

The pressure preferably assumes values in the range from 50 to 250 bar, preferably from 150 to 200 bar, whereas the temperature preferably assumes a value in the range from 18 to 250 ° C, preferably from 180 to 240 ° C. The ranges are particularly suitable for the production of the separating element according to the invention. The pressure can of course also be generated by the weight of the upper mold half.

The entire press cycle (warm-up, pressing and cooling) lasts between 45 and 60 minutes. The resulting laminate is known in the art as HPL ("High Pressure Laminate"), whose characteristics include a very high quality and durability.

The two grooved tool halves are preferably brought together with spacers defined for the purpose of curing the introduced laminate and in order to achieve a good dimensional stability of the separating element.

In a further embodiment of the method according to the invention, the main body of the hinge can be poured into the laminate in the case of overlapping on both sides. An addition which represents the upstream overlap can then be subsequently removed, preferably separated off.

Also, the laminate comprising at least two layer layers, in particular the hinge, can be pressed with oversize and then subsequently machined onto the finished contour, preferably laterally.

In essence, the basic method of making the separator of the present invention may be modified in many ways depending on operational requirements. However, these possible modifications are mostly within the knowledge of the skilled person.

The separating element according to the invention can be used preferably in a single-layer headbox of a machine for producing a fibrous web, in particular a paper, board or tissue web, as a lamella or in a multi-layer headbox of a machine for producing a fibrous web, in particular a paper, board or tissue web Separating blade for separating two or more pulp suspension streams preferably having different properties, in particular texture or consistency use.

A single-layer headbox known to the person skilled in the art is, for example, in the already mentioned German Offenlegungsschrift DE 199 62 709 A1 whereas a multi-layer casserole is disclosed, for example, in the already mentioned German patent application DE 196 52 981 A1 is disclosed.

Further features and advantages of the invention will become apparent from the following description of preferred embodiments with reference to the drawings.

Figures 1A to 1C show schematic and partially sectioned side views of at least one separating element 1 according to the prior art.

The separating element 1 is usually part of a headbox of a machine for producing a fibrous web, in particular a paper, board or tissue web, and comprises a separating element sheet 2 and a hinge 3 arranged at the upstream end 4 for holding the separating element 1 in a machine-width generating device microturbulence ("turbulence generator") (see Figure 1C).

The hinge 3 of the separating element 1 shown in Figure 1A consists of two in cross-section segmented, preferably mirror-image hinge halves 5.1, 5.2, which are connected to the separator sheet 2 at the upstream end 4, preferably glued or riveted. The riveting is carried out in a preferred embodiment by means of a plurality of mutually spaced rivets 6. The separator element sheet 2 in the present case further consists of two symmetrical halves 7.1, 7.2, which are interconnected along their greatest length, in particular glued.

However, the two parts 2, 3 are not directly connected to each other, but rather are connected to one another via an additional, U-shaped hinge support 8. The usually made of a metal or plastic hinge carrier 8 takes in its U-shaped opening 9, the separator element sheet 2 form-fitting or non-positively on, whereas the hinge 3 is mutually the U-shaped opening 9 is mounted positively. The separator sheet 2 is executed in several layers in a known manner.

The separating element can be worked in a further, but not explicitly shown embodiment also from the "full", so machined from the separator sheet, preferably be milled.

FIG. 1C shows two separating elements 1 according to the prior art in respective schematic and partially sectioned side view. The two separating elements 1 essentially correspond to the separating element 1 shown in FIG. 1A.

The two each having a hinge 3 having separating elements 1 are each connected via a preferably hinge-like holder 10 with the turbulence generator 5. According to the state of the art, the turbulence generator 5 consists of a multiplicity of turbulence channels 11 of very different shapes arranged in rows and in columns next to one another and one above the other. In the present case, three lines Z1, Z2, Z3 of turbulence channels 11 are shown.

The respective holder 10 is accommodated in an installation space 12 lying between two adjacent rows Z1, Z2 and Z2, Z3 of turbulence channels 11. The individual holder 10 is formed by a provided with a slot 14 rail 13 which is either directly connected to the adjacent turbulence channels 11, for example by means of at least one weld (illustration), or which is connected to a arranged in the installation space 12, not shown filling piece , For example by means of several screw connections (see Figure 3).

The known dividing elements 1 shown by way of example in FIGS. 1A to 1C, which have at least one separating element sheet 2 and a hinge element 3 arranged at the upstream end 4, have a range of between 2 due to the mechanically necessary design of the hinge element 3 carrying the hinge element 3 and the realizable hinge diameter DS 12 to 18 mm relatively large recesses R, for example in the range of 8 to 10 mm, between the separating elements 1 and the adjacent turbulence channels 11 of the turbulence generator 5 of the headbox on. This results in coarse macro turbulences, which under certain circumstances along the respective partition element 1 along migrate through the headbox and affect the material jet negative and also uncontrollable. This can lead to larger and unacceptable disturbances and inhomogeneities in the fibrous web to be produced. For the sake of clarity, the two dimensions DS, R are only shown on the lower separating element 1 of FIG. 1C.

2 shows a schematic and partially sectioned side view of a first embodiment of a separating element 1 according to the invention, which in turn has a separating element sheet 2 and a hinge 3 arranged at the upstream end 4 for holding the separating element 1 in a machine-wide device for generating microturbulences (FIG. Turbulence generator ") (see Figure 3).

The separating element sheet 2 of the illustrated separating element 1 according to a first embodiment of the invention is formed from a laminate 15 comprising a total of four layer layers S1 to S4. The layer layers S1, S2 represent the lower layer layers, whereas the layer layers S3, S4 represent the upper layer layers. As a rule, the number of lower and upper layer layers is the same; however, it can also be different. In addition, the layer layers S1 to S4 consist of the same, approximately the same or even different materials. If they consist of different materials, the layer layers of the same materials are, if possible, arranged in mirror image to the longitudinal axis L of the separating element sheet 2.

The laminate 15 of the separator element sheet 2 may be formed in a further, but not shown embodiment also of at least three layers, wherein the upper layer layer and the lower layer layer preferably consist of the same or approximately the same materials and wherein the at least one middle layer layer at least in the upstream end region is arranged.

The respective layer layer S1 to S4 of the illustrated separator element sheet 2 has a layer thickness d1 to d4 in the range of 0.3 to 3.0 mm, preferably 0.4 up to 2.0 mm. The separator sheet 2 thus has a thickness DT of about 4 mm. As a rule, the thickness DU of the lower layer layers S1, S2 is equal to the thickness DO of the upper layer layers S3, S4; however, they can be different. If the layer layers S1 to S4 have different layer thicknesses d1 to d4, then the layer layers of the same layer thicknesses are, if possible, arranged mirror-inverted to the longitudinal axis L of the separator element sheet 2.

Furthermore, the hinge 3 comprising a main body 16 is embedded between the middle layer layers S2, S3 of the laminate 15. The two outer layer layers S1, S4 naturally surround the base body 16, which has a circular cross-sectional shape Q. The base body 16 is formed from a solid material and it preferably consists entirely of a metallic material, in particular stainless steel or titanium. In a further, but not explicitly shown embodiment, the base body 16 may also have an oval, an elliptical or a polygonal cross-sectional shape Q, preferably completely made of the same material as the layer layers of the laminate and / or be formed from a hollow material.

The hinge-forming portions B1, B4 of the outer layer materials S1, S4 have specially set resin properties such as friction in the hinge portion BS or wear resistance of the hinge 3. To do so, they are provided with friction reducing particles 17 (dotted line) such as graphite , Mistake. Alternatively or in addition, they can also be provided on the outside with at least one coating 18 (dashed representation), such as a film or a coating, so that the friction in the hinge area can be minimized.

FIG. 3 shows a use of two separating elements 1 according to the invention in a headbox. The two separating elements 1 essentially correspond to the separating element 1 shown in FIG.

The two each having a hinge 3 having separating elements 1 are in turn each via a preferably hinge-like holder 10 with the turbulence generator 5 connected. According to the state of the art, the turbulence generator 5 again consists of a multiplicity of turbulence channels 11, which are arranged in rows and in columns next to one another and one above the other. In the present case, three lines Z1, Z2, Z3 of turbulence channels 11 are shown.

The respective holder 10 is accommodated in an installation space 12 lying between two adjacent rows Z1, Z2 and Z2, Z3 of turbulence channels 11. The individual holder 10 is formed by a rail 13 provided with a slot 14, which is either directly connected to the adjacent turbulence channels 11, for example by means of at least one weld (see FIG. 1C), or connected to a filling piece 19 arranged in the installation space 12 is, for example by means of several screw 20 (representation).

The separating elements 1 according to the invention each have a hinge diameter DS in the range of 6 to 10 mm and thus relatively small recesses R, for example in the range of 4 to 6 mm, to the adjacent turbulence channels 11 of the turbulence generator 5. For the sake of clarity, the two dimensions DS, R are only shown on the upper separating element 1 of FIG.

Figures 4A to 4D show schematic and partially sectioned side views of an embodiment of a separating element 1 according to the invention during its manufacture.

The laminate 15 comprising four layer layers S1 to S4 in the present embodiment is pressed under pressure p (arrow) and temperature T into two grooved tool halves 21U, 21O, which are shown only schematically, and which depict the preferably finished outer contour of the separating element 1. The two tool halves 21U, 21O are shown spaced apart in the illustration of Figure 4A, as is the case for example during their assembly.

Before pressing the laminate 15, the two lower layer layers S1, S2 are introduced into the lower mold half 21 U. Thereafter, the main body 16 comprehensive hinge 3 in the region of the groove 22 to the top in the lower mold half 21 U introduced layer layer S2 applied. Subsequently, the further layer layers S3, S4 applied to the already in the lower tool half 21 U introduced layer layers S1, S2. And finally, the upper mold half 210 is brought to the last applied layer layer S4 under pressure p (arrow) and temperature T to preferably complete curing of the laminate 15 between the two mold halves 21 U, 21O.

The pressure p (arrow) assumes a value in the range from 50 to 250 bar, preferably from 150 to 200 bar, during the pressing, whereas during the manufacturing process the temperature T has a value in the range of 18 to 250 ° C., preferably 180 to 240 ° C, assumes. The pressure p (arrow) can also be generated by the weight of the upper mold half 21O.

The two grooved mold halves 21 U, 21 O can be moved together with indicated spacers 23 for the purpose of curing the introduced laminate 15 and in order to achieve a good dimensional stability of the separating element 1. The arranged on the lower mold half 21 U spacers 23 can of course also be the upper mold half 210 or even mutually arranged.

According to the representation of FIG. 4B, the base body 16 of the hinge 3 of the separating element 1 can be cast into the laminate 15 in the case of overlapping Ü1, Ü2 on both sides (dashed representation). The downstream overlap Ü1 corresponds to the separating element sheet 2 of the separating element 1. The addition 24 representing the upstream overlapping Ü2 can be subsequently removed, preferably separated, as shown for example in FIG. 4C, which shows a ready-to-install separating element 1.

Also, in the production of the separating element 1, the production of an upstream overlap may likewise be dispensed with, for example by folding the layer layers S1, S2 around the main body 16 of the hinge 3 of the separating element 1. The downstream overlap Ü1 still corresponds the separating element sheet 2 of the separating element 1. This possibility is shown for example in FIG. 4D.

In general, the laminate 15 comprising several layer layers, in particular the hinge 3, can be pressed with oversize and subsequently machined onto the finished contour of the separating element 1, preferably by machining.

The separating element 1 according to the invention can preferably be used in a single-layer headbox of a machine for producing a fibrous web, in particular a paper, board or tissue web, as a lamella or in a multi-layer headbox of a machine for producing a fibrous web, in particular a paper, board or tissue web, as a separating blade for separating two or more pulp suspension streams preferably having different properties, in particular texture or consistency use.

In summary, it should be noted that a separator of the type mentioned is improved by the invention so that the return between the separator and the adjacent turbulence channels of the turbulence generator of the headbox is significantly reduced. Also, the manufacturing cost of the separator, especially in terms of cost and time, is significantly reduced.
