Definitions
- the invention relates to a calender with at least a roll stack of a maximum of three rolls, the at least forming a nip bounded by two rollers is, and with a stator assembly attached to each axial End of the roll stack has a stand, in the rollers are stored with the help of roller bearings are.
- Such a calender also called “soft calender” is mainly used in paper production used. Since he only has one or two nips per Roll stack has, he is particularly as a machine calender suitable, which can be used in-line, i.e. immediately after a paper machine.
- a known calender of the type mentioned has a substantially vertical roll stack with two rollers, with the two rollers in one L-shaped stand are arranged.
- This embodiment has the advantage that both rollers with the help of a crane can be removed and installed, including the lower Roller.
- EP 1 092 805 A2 shows a calender with two roller stacks four rolls each, facing the vertical are inclined towards each other.
- the two roll stacks are arranged on a common stand, which in the side view the shape of a triangle miteiner Has passage opening.
- the rollers are on the Stand partly fixed with levers, partly with lateral guides.
- the invention is based on the object, a soft calender specify that can be operated at high speed is and in which a roll change easily possible is.
- the stand a bearing edge, where the roller bearings are arranged and the relative to the vertical by an angle in the range of 30 ° to 60 ° inclined, a ridge, with the the stand is standing on a footprint and the extends below the bearing edge, and a connecting edge which has a connection between the Bearing edge and the ridge edge, the bearing edge, the uprising edge and the connecting edge communicate with each other through a plate that on the bearing edge a mounting surface with mounting holes for roller bearings or other attachments provides.
- the stands have a very wide contact surface, which is characterized shows that the uprising edge the bearing edge supported over its entire length.
- This support is realized by a plate, so that between the uprising edge and the bearing edge no points of articulation or other connection points are formed, the could deform in a critical way.
- the plate gives the stand an extremely large Rigidity. Due to the inclination of the bearing edge opposite The vertical is indeed a surface expansion of the stand, but the height is reduced.
- the plate may well have openings, as required for assembly or maintenance purposes. Overall, however, it can be assumed that the Plate essentially in fact a two-dimensional design has, accordingly, a high mechanical Stability offers.
- the rollers can be stored here without lever become. Either you can parallel them to the Move storage area or they are rollers with coat stroke.
- the plate has a thickness of at least 150 mm, in particular at least 200 mm.
- the Choosing a relatively "thick" plate has several advantages: On the one hand this results in a high mechanical Stability. On the other hand, there is one in the edge of the warehouse sufficiently large area available to mounting holes for roller bearings or other attachments provided. Such a trained stand is essential stiffer than the previously known stand whose Columns and trusses designed as a box construction were, i.e. by a box-like welding together comparatively thin sheets with a Thickness in the range of 20 mm.
- the plate is formed by a sheet, which essentially has the shape of a triangle.
- Sheet metal should also metal plates with the above Strength to be understood.
- Such a thing Triangle is easy to make. They are only a few cuts required to change the shape of the Triangle to determine. In addition, there is a pleasing appearance.
- the triangle capped Has peaks This holds the one needed Space small and saves on the other material. It is assumed that the tips of a triangle do not have much contribute to the stability of the stand, but on the contrary pose a risk that vibratory Parts are formed.
- the triangle is a right triangle formed, the Hypothenuse forms the bearing edge.
- the space required for the stand kept as small as possible.
- the riot point is shorter compared to the bearing edge.
- the connecting edge is vertical in this embodiment, so that they as Orientation surface or edge can be used for attachments that require vertical alignment.
- two roll stacks are provided by each having a plate-like at each axial end Stands having a substantially triangular shape, wherein connecting edges are vertically aligned and each other are adjacent.
- the training with two roller stacks is known in and of itself. It makes it possible that the web initially with its first page a hard roller and with its opposite second side on a soft roll, i. a roller with a resilient or compliant surface, while in the next roll stack the conditions just the opposite, i. the second page is on the soft roller and the first side on the hard Roller.
- rollers Of course it is also possible in every roll stack only use rollers with a similar surface. If you now the connecting edges vertically aligns and the stands mirrored or mirror-symmetrical to each other, then you can the Stand with a relatively small distance from each other position. This in turn keeps the required installation space small.
- a calender 1 is at the exit one only schematically illustrated paper machine 2 arranged to one out satinize the paper machine coming train 3.
- the calender 1 has a first roll stack 4 with a hard roller 5 and a soft roller 6.
- the hard roller 5 is formed of metal and has a hard but very smooth surface.
- the soft Roller 6 has an elastic reference, so that the Surface of the soft roller 6 is elastic. Between the hard roller 5 and the soft roller 6 is a nip formed, which accordingly as a "soft" nip referred to as.
- the use of a hard and a Soft roller is not mandatory. It can also similar rolls can be used.
- the rollers 5, 6 are rotatably mounted in roller bearings 8, 9.
- the Both roller bearings 8, 9 are fastened to a stand 10. It is obvious that a corresponding Stand 10 at both axial ends of the rollers 5, 6 present is.
- On the stand 10 are also attached attachments, For example, a guide roller 11, doctor blades 12 or an adjusting drive 13.
- the stator 10 has the shape of a substantially right-angled, isosceles triangle on, where the tips 14, 15 of this triangle with acute angles are cut. They are therefore merely illustrative dashed lines.
- the hypotenuse of the triangle forms a bearing edge 16
- the lower Kathede forms a ridge edge 17
- the other Kathede forms a connecting edge 18.
- Die Aufstandskante 17 stands on the floor 19, optionally with the interposition of a base plate 20th
- the stator 10 is formed by a metal sheet, which is a Thickness of 200 mm or more. Accordingly arise at the individual edges 16 - 18 surfaces of corresponding width.
- the stand 10 can therefore on the Riot edge 17 without further action itself stable stand.
- At the bearing edge 16 there is a mounting surface, at the roller bearings 8, 9 are attached can. For this it is possible, for example, threaded holes in the area at the bearing edge 16 introduce.
- the triangle is not only rectangular, but also isosceles. This is however no unconditional requirement. Instead of the illustrated Inclination of the roll stack from the rolls 5, 6 from 45 ° to the vertical is a slope in the range of 30 ° to 60 ° possible. It is favorable, however, if As shown, the ridge edge 17 the bearing edge 16 supported over the entire length. The relatively large one Stiffness of the stator 10 results from the fact that the individual edges 16 - 18 through the plate of the stand 10 are connected to each other.
- the calender 1 has a second roll stack 4 ', with respect to the stator 10 'mirror-symmetrical to Stand 10 is aligned. Corresponding one another Parts are therefore provided with primed reference numerals.
- the roll stack 4 ' has the soft roll 6' in the upper position and the hard roller 5 'in the lower Position up. Accordingly, the web 3 becomes once with their top and once with their bottom on the hard rollers 5, 5 'passed while they first with the bottom on the soft roller 6 and then passed with the top of the soft roll 6 ' becomes.
- the two connecting edges 18, 18 ' are vertical or vertical. They are adjacent to each other, so that one gets along with a relatively small space altogether. Between the two stands 10, 10 'is still a walk-in stage 21 arranged, if necessary can also be designed adjustable in height. This can be used for maintenance purposes.
- the roll stacks 4, 4 'can instead of the illustrated two rollers also have three rollers.
