Definitions

the invention relates to a calender with at least a roll stack of a maximum of three rolls, the minimum form a nip delimited by two rollers is, and with a stator assembly, which on each axial End of the roll stack has a stand in where the rollers are stored with the help of roller bearings are.
Such a calender which is also called a "soft calender” is mainly used in paper production used. Since he only has one or two nips per Has roll stack, it is particularly as a machine calender suitable that can be used in-line, i.e. immediately after a paper machine.
a known calender of the type mentioned has an essentially vertical roll stack with two rollers, the two rollers in one L-shaped stands are arranged. This configuration has the advantage that both rollers with the help of a crane can be removed and installed, including the lower one Roller.
the invention has for its object a soft calender specify which can be operated at high speed and with which a roll change is easily possible is.
This task is performed on a calender of the type mentioned at the beginning kind solved in that the stand has a bearing edge, on which the roller bearings are arranged and the to the vertical by an angle in the range of Is inclined 30 ° to 60 °, a riot edge with which the stand is on a footprint and the extends below the bearing edge, and a connecting edge has a connection between the Bearing edge and the contact edge forms, the bearing edge, the riot edge and the connecting edge communicate with each other through a plate.
the stands have a very wide contact surface, which is characterized by shows that the riot edge is the bearing edge supported over its entire length.
This support is realized by a plate, so that between the riot edge and the bearing edge have no hinge points or other connection points are formed that could deform in a critical manner.
the plate gives the stand an extraordinarily large size Rigidity. Due to the inclination of the bearing edge the vertical results in a flat expansion of the stand, but the overall height is reduced.
the plate can have openings as they are required for assembly or maintenance purposes. Overall, however, it can be assumed that the Plate essentially has a flat design has accordingly a high mechanical Offers stability.
the rollers can be stored here without levers become. You can either run them parallel to the Move storage space or it is rollers with jacket stroke.
the plate preferably 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 bearing edge Sufficiently large area available for fastening openings for roller bearings or other attachments provided.
a stand designed in this way is essential stiffer than the previously known stands, whose Columns and trusses designed as a box structure were, i.e. by box-like welding of comparatively thin sheets with a Thickness in the range of 20 mm.
the plate is preferably formed by a sheet metal, which essentially has the shape of a triangle.
Sheet metal should also be metal plates with the above Strength can be understood.
Such a thing Triangle is easy to make. They are just a few cuts required to fit the shape of the To determine triangle. In addition, there is a pleasing appearance.
the triangle is capped Has peaks. On the one hand, this keeps the required Small installation space and saves on the other material. It is believed that the tips of a triangle are not much contribute to the stability of the stand, on the contrary pose a risk that vibrating Parts are formed.
the triangle is preferably a right-angled triangle trained, the hypotenuse forms the bearing edge. So the space that you need for the stand is kept as small as possible.
the riot edge is shorter than the bearing edge.
the connecting edge stands vertically in this embodiment, so that it as Orientation surface or edge can be used for attachments that require vertical alignment.
each roll stack Preferably two roll stacks are provided, by which each have a plate-like shape at each axial end Has a stand with a substantially triangular shape, connecting edges aligned vertically and each other are neighboring.
Training with two roller stacks is known in and of itself. It enables that the material web first with its first page a hard roller and with its opposite second side on a soft roller, i.e. a roller with an elastic or resilient surface, while in the next roll stack the conditions are exactly the opposite, i.e. the second side is on the soft roller and the first side on the hard one Roller.
rollers Of course it is also possible in every roll stack only use rollers with a similar surface. If you now connect the connecting edges vertically aligns and the stands mirror-inverted or mirror-symmetrical to each other, then you can Stand with a relatively small distance from each other position. This in turn keeps the space required small.
a calender 1 is only schematic at the exit of one shown paper machine 2 arranged to one out web 3 coming from the paper machine.
the calender 1 has a first roll stack 4 with a hard roller 5 and a soft roller 6.
the hard roller 5 is made of metal and has one hard but very smooth surface.
the soft Roller 6 has an elastic cover, 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, however. It can similar rollers can also be used.
the rollers 5, 6 are rotatably supported in roller bearings 8, 9.
the two roller bearings 8, 9 are attached to a stand 10. It is obvious that an appropriate one Stator 10 at both axial ends of the rollers 5, 6 available is. Attachments are also attached to the stand 10, for example a deflection roller 11, doctor blades 12 or an actuator 13. These elements are only shown schematically and their enumeration is not final.
the stand 10 has essentially the shape of a right-angled, isosceles triangle, where the tips 14, 15 of this triangle with acute angles are capped. They are therefore only for explanation shown in dashed lines.
the stand 10 is formed by a sheet metal, the one Has a thickness of 200 mm or more. Accordingly 16 - 18 areas of corresponding width.
the stand 10 can thus on the Riot edge 17 itself stable without further measures stand.
a mounting surface then exists on the bearing edge 16, to which the roller bearings 8, 9 are attached can. For this, it is possible, for example, tapped holes to bring into the surface at the bearing edge 16.
the triangle is not only rectangular, but also isosceles. However, this is not an absolute requirement. Instead of the shown Inclination of the roll stack from the rolls 5, 6 of 45 ° to the vertical is an inclination in the range of 30 ° to 60 ° possible. However, it is favorable if, as shown, the contact edge 17 the bearing edge 16 supported over the entire length. The relatively big 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.
the calender 1 has a second roll stack 4 ', which is mirror-symmetrical with respect to the stand 10 ' Stand 10 is aligned. Corresponding to each other Parts are therefore provided with deleted reference numerals.
the roll stack 4 ' has the soft roll 6' in the upper position and the hard roller 5 'in the lower Position on. Accordingly, the lane 3 becomes one with their top and once with their bottom passed the hard rollers 5, 5 'while initially with the bottom on the soft roller 6 and then passed the top of the soft roller 6 ' becomes.
the two connecting edges 18, 18 ' are vertical or vertical. They are adjacent to each other, so that you get along with a relatively small space overall. There is still between the two stands 10, 10 ' an accessible stage 21 arranged, if necessary can also be height adjustable. This can be used for maintenance purposes.
