Modular system for the construction of any column arrangement of roller machines, especially calenders.

The invention relates to a modular system for the construction of any stand arrangements of roller machines, especially calenders as used in the processing industry, especially in laboratories will.

Xn the plastics, rubber, paper, textile and food industries and process engineering are used in large numbers to carry out processing operations perform. There are single-roller arrangements with fixed counterparts, two-roller arrangements, so-called. " Rolling mills, three- and multi-roll arrangements with the most varied of relative positions of the rolls to one another are used

According to the state of the art, for each of these arrangements, specially made, complete machines built. The rollers are in a special frame or with their bearings Arranged stand, which encloses all roller bearings and a unit with the entire machine forms that cannot be changed or can only be changed with considerable effort.

A device is also known in which three rollers are mounted in a frame, one of which

to be removed a greater distance from the others can, so that only two rollers can be used can·

There is also a roll stand, in particular for calenders, known, which can be detached from several Connected parts consists, with each roll stand at least four parts belong, which partially are equal in the recesses of the compound Stands sit as usual, the roller bearing jewels »The Parts can be assembled in various ways to form columns for different calender arrangements · Bs is thus made possible, a certain amount of storage to achieve and reduce manufacturing costs.

All of the prior art machines described have the decisive disadvantage that they can essentially only be used in a manner that has been defined for one or a few specific purposes. Bas latter modular system for the roll stand already allows for greater variability, but has always nossli u®u disadvantage that!

diameter is usually only a standard component for the Construction »more functional for whale machines Arrangements is required - apart from a base plate, which ensured the axial fixation

The invention accordingly consists in the fact that in a system mentioned at the outset without the use of a special one Machine stand the stand part receiving the bearings from the uniformly designed bearing housings of the roller bearings constructed or composed of standard bearing modules, each containing a roller bearing

The actual one-part or multi-part, several, used in all previously known devices Stator components surrounding the bearing can therefore be omitted; they are made by firmly joining the bearing housings or Standard bearing blocks replaced

The result is the simplest possible modular system, namely a system which essentially uses only one unit element the construction of any * structures enables.

The building block system essentially consists of one or two bearing blocks each assigned to a roller, which are shaped in such a way that a circular polygon arises, weaving the diameter of the enclosed one Circle is essentially equal to the roller diameter, and the bearing blocks on all sides with the same Connection surfaces are provided so that others are the same Blocks can be connected to any side of the first block

The sides of the polygon can be of any length; for practical reasons, however, they are equally long Pages preferable

- k 209844/0541

In particular, it is favorable to choose a four-cornered, that is to say square, shape of the bearing blocks, vobei the side lengths of the square are equal to the roller diameter

It is also conceivable, however, that the building block is designed as a hexagon, for example, with 6 additional bearing blocks can be connected to a central storage unit

By stringing any number of such storage buildings together a roller machine of any kind can be built on any side

The connection of the individual bearing blocks to one another is done in a simple manner by screws, which penetrate the flanges arranged at both ends of each side of the building block "

A connection by brackets is also conceivable, which each overlap a joint between 2 building blocks

A special feature of the bearing blocks is that the connecting flanges on at least one side ^ are only located at the outer ends of the page, but there is a recess in between through which a Direct view of the nip created between two rolls to observe the processes in the nip will.

The roller bearing, which is located centrally in the middle of the block, can also be made using a special Device can be sensitively shifted from the center position for the purpose of setting an exact gap width between two adjacent rollers · This device does not stand above the side line of the square of the cross-section of the bearing block

- 5 209844/0541

The displacement device can consist, in a known manner, of a screw which supports the bearing look, which is guided in separate lateral guides moves, or it can consist of at least one eccentric ring, which surrounds the bearing and duroh the rotation of which results in a radial change in position of the roller bearing

If necessary, a bursting plate can be installed between the displacement device and the bearing module in a known manner which breaks when an impermissibly high force arises.

The roller, which is mounted in one or both sides in 2 bearing blocks, can be made in one piece with brackets and Channels for heating and cooling, or two-part with removable «and exchangeable sheaths. It is particularly advantageous in the laboratory to have the ratio of roll width to roll diameter approximately the same or to be dimensioned smaller than 1

The roller is driven particularly easily by a drive unit attached directly to the roller stump, which in the outer dimensions is essentially no larger than the bearing block, so that any Lining up structural units and the drives of each individual shaft are not mutually exclusive hinder · The drive is supported against the bearing block with a torque arm · For the purpose of To measure the torque, a load cell can be inserted into the support point · The one attached to the roller shaft The drive advantageously consists of a centrally constructed gear, e.g. a planetary or cyclo gear, and a drive that is as light and low-inertia as possible, e.g. an electric disc rotor or a Hydraulic motor

209844/0541

It is also possible to turn the drive into a special To store the drive module and to connect it to the roller via a cardan shaft; Such a drive module also corresponds in its external dimensions to Bearing blocks

Additional modules for special functions can be added to the bearing modules; are all of these building blocks in at least two sides of the same length as the bearing block and they all have the same screw pitch, so that all building blocks can be lined up in any order

»Can» There can be provided: A module with worm gear, for the sake of simplicity and more precise adjustment of the roller axis; a module with built-in hydraulic or pneumatic cylinder for direct roller pitching, e.g. in smooth rolling mills;

a housing component with the same external dimensions like the bearing block;

a housing component with longitudinal sides of the same length, but shorter or longer length of the transverse sides, whereby the transverse sides are divided in such a way that η building blocks again form a square building block or vice versa, can be composed;

ψ an angle building block, in which one side of the square is bevelled at an angle, for the construction of inclined arrangements, whereby the length of the. The base side and the sloping side are equal to the side length of the standard or base bearing block;

Finally, a base plate is used to build all the modules described here and to define the Bearing clearance.

Finally, a series of bearing blocks and other blocks is created that are graded in such a way that

- 7 209844/0541

that their diameter or edge lengths by a increase integer multiple of a certain division, either linear, e.g. 1t, 2t, 3t, or according to a geometric one Row 2t, ^ t, 8t, so that all building blocks,

also those of the different type series, in turn, can be combined with one another.

Other components, such as axial spacers for the bearing blocks, side limiting jaws to the side Completion of the roller gap, attachable hopper, scraper for removing material from the roller as well a detachable safety off switch, among other things can be screwed on at will and receive correspondingly standardized connection divisions »

The advantages that can be achieved with the invention are primarily that instead of a large number of different Standard parts for the various applications only a single standard part is used to build the stand part, and these standard parts together with a base plate and, if necessary, some standardized additional modules, the structure of any Roller arrangements enables · The desired structure can be set up in a very short time by simply putting together and spoiling can be achieved

Xm laboratory operation can, after the end of the experiments, the Machine can be dismantled immediately and used in a new configuration for new experiments »So it's opposite the previously customary state of the art, a significantly more favorable capital utilization is possible.

Even more important today in research and development, that no tent is lost in order to carry out necessary experiments; it would take months to build a new special machine claim, with the modular system according to the invention, the new arrangement is realized in a few hours. This is especially true with unconventional new ones

209844/0541

Arrangements, ζ · Β · single roller calenders, cross-shaped Calenders or rectangular four-roll calenders to carry, which are not from the previously known stand parts can be put together

In terms of process and measurement technology, the advantage is that now through the recesses in the building blocks all working gaps can be observed directly *

Furthermore, the floating arrangement of the drives on the shaft simplifies the structure and on the other hand, there is a very simple and precise possibility of measuring the torque on each roller the advantage that in the event of a transverse displacement of the roller, the drive is forcibly moved with it and no additional one complicated articulated connection between roller and drive is required

The advantage of the lightweight drive elements is a low load on the roller stump, and especially in a very easy assembly of arrangements due to the low weight

The advantage of drives with low-inertia gears and motors ultimately has the advantage that an emergency stop is possible immediately in case of danger, while with conventional calender drives the large revolving gearbox and engine dimensions only with special additional equipment

" is possible.
