Definitions

  • the invention relates to a calender for webs made of paper or similar material with two at one Stand arranged in a common plane Roll stacks, each a top roller, a bottom roller and have three intermediate rollers, the top roller and the lower roller each as a deflection adjusting roller with a deflection adjustment device jacket supported on a non-rotatable support are trained.
  • Deflection adjusting rollers are known from DE 30 04 913 C2 of the jacket lift type as the top and bottom roller of a roller stack known. But here is the coat in operation who ran one end roller up to a stop, so that the position of the jacket fixed relative to the stand is.
  • the invention has for its object a calender of the kind described at the beginning, that he's used to produce a variety of different Paper quality is suitable.
  • the deflection adjustment device consists of a row of support elements that together with a stroke guide by means of an adjusting device is displaceable by an angle of 180 °.
  • the adjusting device By simple actuation of the adjusting device becomes the desired one Direction of action reached. In the simplest case becomes the entire support on which the support elements and the stroke guide are attached, rotated by 180 °.
  • each roll stack is mounted on levers, that swivel around fixed swivel axes. These intermediate rolls can therefore change with little friction follow the load from the lower rollers. By lowering the lower roller, those below open of the top nip located nips automatically.
  • All rollers of the two roller stacks expediently have own drive. This supports the Passing the web through the opened nips.
  • the calender is also suitable for online operation.
  • the rollers' own drive enables one flawless insertion of the at high speed incoming paper web. When breaks because of the repair or replacement of a roller may be required the paper web is still treated in the additional nip, making usable paper of a different quality arises, but the amount of paper returned to the pulper can be kept small.
  • the common level runs obliquely to the horizontal and that the approximately parallel to this stand both below as well as supported above. Through the inclination is the prerequisite created for the stand to support two places. Thanks to the double support there is a largely vibration-free stand.
  • the height is less than that of a vertical stand with ten rollers arranged one above the other.
  • the length is shorter than two vertical 5-roll calenders, which are arranged one behind the other.
  • 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.
  • the bearings for the carrier at least which have a deflection adjustment eccentric, with which the distance between the neighboring ones Deflection adjustment rollers can be reduced.
  • the bearings for the carrier at least which have a deflection adjustment eccentric, with which the distance between the neighboring ones Deflection adjustment rollers can be reduced.
  • the eccentric together with the carrier can be rotated through 180 ° by the adjusting device are. It is therefore sufficient to set the Adjustment of carrier and eccentric.
  • 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.
