Definitions

  • the invention relates to a calender arrangement for webs of paper or similar material with a stands supported at the bottom and at least five on them held rollers, the axes of which are roughly parallel lying on the common level.
  • DE 195 34 911 C2 is the schematic drawing of an 8-roll stack can be seen, the middle level of about Is inclined at 60 ° to the horizontal.
  • the invention has for its object the stand a calender arrangement of the type described in the introduction to give the lowest possible tendency to vibrate.
  • the inclination of the stand makes this possible created to support him both below and above.
  • the tendency to vibrate is reduced by the 2-point support compared to one supported only below Stand significantly reduced.
  • the stand as a whole also with a lower stability, that is, lighter and cheaper.
  • the bearing surfaces preferably run horizontally. On this way the vertical forces on it mainly arrives, well derived.
  • top as well as the bottom bearing surface formed by a concrete foundation (column, base or the like) is.
  • a concrete foundation can be essential on site be provided more cheaply than on the stand attached supports.
  • the stand has an upper support surface has, which is formed on a support leg, located near the top of the stand on this is.
  • the common plane preferably runs in one Angles from 30 to 60 ° to the horizontal. In the cheapest Case the angle is about 45 °. That way the height of the stand is smaller than that of a 10-roll calender with rollers arranged vertically one above the other and the length is shorter than a calender with two 5-roller stacks arranged side by side in parallel.
  • the stand between the last drying cylinder and a winder that is about are at the same height.
  • the height of the stand is reduced so far that the web between drying cylinder and calender as well as between the calender and the winding device low gradient can run. This in turn makes it easier the introduction of the web, which is favorable for the Online operation is.
  • rollers on the inclined Top of the stand are arranged and at least a roller at right angles by means of an adjusting device is shiftable to the level. It is enough to roll over to drive a relatively short distance so they immediately grabbed by a crane and after can be removed at the top.
  • a calender 1 made for the treatment of webs Paper and similar material, such as cardboard has an upper 5-roll stack 2 and a lower one 5-reel stack 3 on.
  • the upper roll stack 2 consists of the top roller 4, three intermediate rollers 5, 6 and 7 and the lower roller 8.
  • the lower roller stack 3 consists of the top roller 9, three intermediate rollers 10, 11 and 12 and the lower roller 13.
  • the top and bottom rollers 4, 8, 9 and 13 are deflection adjustment rollers of the jacket lift type, which are among themselves can have the same structure, so that with one reserve roller for all four end rollers.
  • a deflection adjustment roller has 4 a jacket 14 which over a Deflection adjustment device 15 on one in operation Supported rotatably supported on the stand 6 support 17 is.
  • the deflection adjustment device 15 exists in the present example from a series of hydrostatic Support elements 18 in a known manner via a pressure chamber 19 each with pressure medium be supplied that the deflection adjustment 15 also serves as a loading device.
  • To the The ends of the roller jacket 15 are on a bearing ring 20 mounted in the stroke direction on a stroke guide 21 is movable.
  • roller jacket 14 is therefore over its entire length is movable in the stroke direction. Moreover is still provided for the deflection adjustment rollers, that the carrier 17 with the help of an actuator 22 can be offset by an angle of 180 ° (cf. the arrow 23 in Fig. 2), so that the direction of action of Deflection adjuster 15 in the opposite Direction points as this by the dash-dotted line arranged row of support elements 18 'illustrated is.
  • the top intermediate rollers 5 and 10 are fixed to the stand 16 stored. If 4 and 9, the deflection adjuster 15 shown in FIG Fig. 2 has illustrated position, the paper web 24 in the first nips 25 and 26 in the direction of passage the upper roll stack 2 or the lower roll stack 3 with very high line load and therefore high Compressive stress are treated.
  • the intermediate rollers 6, 7, 11 and 12 are each on a lever 27 stored, about a fixed pivot axis pivots. If the deflection adjusters 15 of the lower rollers 8 and 13 the dashed in Fig. 2 Have the nips 28, 29 and 30 of the top Roll stack 2 and the nips 31, 32 and 33 of the lower one Roll stack 3 loaded accordingly.
  • the amount of the burden is independent of that in the first Nip 25 or 26. There are therefore four sections, in which the paper web 24 is different can be treated so that a variety of different Can produce paper qualities.
  • the upper and lower rollers 4, 8, 9 and 13 and the middle intermediate rolls 7 and 11 are elastic rolls, while the remaining intermediate rolls 5, 7, 10 and 12 are heated hard rollers. But it also comes other combinations, for example with hard top and Bottom rolls, into consideration.
  • the distance between the two deflection adjustment rollers 9 and 10 is so low that the additional nip 34 under Utilization of the roller stroke from, for example, 30 to 40 mm can be closed.
  • the additional nip 34 under Utilization of the roller stroke from, for example, 30 to 40 mm can be closed.
  • deflection adjusters 15 of the two end rollers 8 and 9 with the help of the adjusting device 22 towards each other and then that Supply pressure medium with the appropriate pressure.
  • Supply pressure medium with the appropriate pressure.
  • With this additional nip 34 can then be satinized be because the two bending adjustment rollers 8 and 9 wear an elastic cover. Without significant additional There is therefore another possibility paper handling.
  • the carrier 91 of the top roller 9 is mounted in a spherical cap 92 be in turn by an eccentric disk 93 will be carried.
  • the latter is together with the carrier 91 by the adjusting device 22 through 180 ° in the bearing 94.
  • the open additional nip 34 can be opened For example, 80 mm can be held, which is also an opening the nips 28 and 29 relieved.
  • the axes of the rollers 4 to 13 lie approximately in a common one Level E, which is opposite to the horizontal Is inclined at 45 °. Accordingly, the stand has 16 an oblique course. It can therefore be in two places are supported, namely with a lower support surface 35 on a building-fixed bearing surface 36 and with an upper bearing surface 37 on an upper building-fixed Storage area 38.
  • the storage area 37 is located itself on a foot 39, the stand 16 near it upper end is attached.
  • the bearing surfaces 36 and 38 run horizontally and are each on a concrete foundation or base 40 or 41 formed. This is the stand 16 largely insensitive to vibrations.
  • the stand 16 can be less stable than so far and therefore cheaper to manufacture.
  • the calender 1 can work online. He is between the last drying roller 42 Drying section of a paper machine and a winding device 43, for example a slitter and Winding device. Drying roller and winding device are at about the same height and above one Working level 44, which is penetrated by the calender 1. Therefore, the paper web 24 has between the drying roller 42 and the entrance of the calender 1 and between the Exit of the calender 1 and the winding device 43 a relatively weakly increasing course. This makes it easier to insert the paper web in online mode. The same advantage arises when the paper web from the drying roller 42 down into the Calender 1 is inserted and the top of the winding device 43 exits.
  • An only indicated web feeding device 45 the works with rope clamping, for example Start of path through all nips 25 to 33 of the two Roll stack 2 and 3 and the additional nip 34. It is sufficient hence an insertion process for both roll stacks.
  • the Introductory movement is supported by the fact that all Rolling the calender and also the associated guide rolls each have their own drive 46.
  • the paper treatment depends on which one of the mentioned nips are closed.
  • Drawn in dashed lines is a second web insertion device 47, with which only the additional gap 34 is supplied.
  • the matt satinage of a web introduced in this way exists Possibility of repairs on the other rollers or a To make a replacement. Semimatt operation results for example, if only the top one Nip 25 is used.
  • rollers Substitution are more accessible and for example removed with a crane 48 and corresponding crane control and can be used.
  • the bearings of the roller to be replaced by means of a hydraulic actuator 49 along a guide be pulled out perpendicular to plane E, like this is shown in dashed lines in Fig. 1.
  • an actuator 49 comes primarily the piston of one along the lever 27 extending hydraulic cylinder in Consideration.
  • the crane 48 can Hold the roller ends immediately and the roller vertically dissipate.
