Definitions
- the invention relates to a calender arrangement for webs of paper or similar material with a Stand and a stack of rollers held thereon, the Axes in an approximately parallel to an end face, common level.
- Such a calender arrangement is for example from DE 195 34 911 C2 known.
- the roll stack and thus the common plane run vertically.
- this calender arrangement and similar calender arrangements as they do there are difficulties, however when installing and removing the rollers, for example if a change is required from time to time soft roller is necessary.
- the space are so cramped, especially those between top and bottom Bottom roll middle rolls of the stack that the crane operator, after picking up a roller, the crane both horizontally and vertically Direction must be controlled very carefully so that there is no collision done with neighboring rollers.
- the Roller can only be gripped by the crane if previously on the Rolling pin extension sleeves have been put on are.
- the invention has for its object in a calender arrangement accessibility of the type described at the beginning to improve the rollers and in particular to simplify the roll transport by means of a crane.
- rollers are due to the Inclination of the common plane in the horizontal direction offset against each other. It is therefore sufficient to replace the one Roller over a relatively short Extend route so they are gripped by a crane and can be transported away. Since the hub of the Adjustment device can be short, are in the outer position bending moments caused by the roll weight low, so that simple adjusting devices can be used to let.
- the adjusting device prefferably to be displaceable
- the roller extends so far that a crane touches the roller ends grasp immediately and remove the roller upwards can. This results in a particularly simple crane control. Since the crane at the roller ends, that is Cones that can directly attack can be on the cones attachable sleeves, such as those used for vertical stacking Crane transport are not necessary.
- a bearing block for the roller releasably on one connected to the stand Carrier is attached and that the actuator is a has the trough receiving the roller end.
- the roller end is first taken up by the trough and there kept safe.
- the bearing block can be removed after Carrier, i.e. a sled, lever or the like, in the outer position be brought out.
- the adjusting device preferably has a hydraulic cylinder with pistons on. This results in a desired one straightforward, powerful adjustment.
- the displaceable roller is a center roll of the stack. Although in the area there is little space available for a center roll, can be easily pulled out for everyone accommodate the necessary components of the roller.
- the common plane preferably runs in one Angles from 30 to 60 ° to the horizontal. In the cheapest Case the angle is about 45 °. Wear this way the slope of the common plane and the Displacement of the roller perpendicular to this common Level in an optimal way to the side Displacement of the roller to be replaced with respect to the Neighboring roller at.
- 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 16 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 to each other and then the pressure medium feed with appropriate pressure.
- This Additional nip 34 can then be used for a satin finish be because the two bending adjustment rollers 8 and 9 one wear 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 your 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.
- the lever 27 illustrated in Fig. 1 consists of two parts 27a, 27b, one on each side Stackable adjustable carriage 50 arranged and about an axis 51 mounted on this slide are pivotable.
- a Bearing block 52 arranged for the roller 6 and with it releasably connected by screws 53.
- a hydraulic one Actuating device 49 has a hydraulic cylinder 54 with a piston 55, the piston rod 56 with a Driver 57 is connected.
- This driver stands with a slide 58 in connection, which at the upper end carries a fork 59 with a recess 60.
- the hollow is adapted to the roller end 61, that is to say the end pin.
