Description

T racing device

The invention relates to a device for separating feed material, preferably of inhomogeneous feed material, with at least two, in particular as Schnecken shaft formed rotational elements, wherein the rotation elements via at least one, in particular designed as a roller chain, connecting means ei ner drive means are interconnected, so that at least two un indirectly adjacent rotation elements have a direction of rotation coupling.

In particular, the invention relates to the technical field of sorting and / or classification of feedstock, especially in the field of recycling processing and / or waste separation. A clean or sufficiently accurate separation of the feedstock into different fractions makes it possible to use different fractions of the feedstock directly or to be able to supply different aftertreatment processes. Thus, for example, large and / or elongated parts of smaller particles or components of the input material can be separated.

In the context of the invention, the term "separating" includes both classifying and sorting. Here, classifying a mechanical separation process for solid mixtures to understand, with different geo metrical features, such as size, are exploited for the separation process. In this case, a division u.a. in coarse and fine material. As sorting ren in this context, a mechanical separation process is understood in which a solid mixture with different physical characteristics in fractions with the same material characteristics is divided. For sorting, for example, the density, color, shape and wettability or Magnetisier are availability of the feed material. Accordingly, the term separation in vorlie lowing invention comprises a separation of the feed material, so that a division into different fractions can be made. Most of this separation or separation is used for the treatment of recycled material or for the classification of at least substantially solid material.

The rotation elements are arranged such that they form a screen deck, wel Ches is usually used for the classification of solid and lumpy order or feed material. The device for separating is intended for input material from the field of recycling and for waste material, industrial waste and building rubble. The said different task goods have in common that they do not have evenly distributed or inhomogeneous structures and geometries, it may be that the feed material is hooked together. Especially when used in the waste and recycling area for clean or selective classification of the feed an adjustment of the screen deck or the screen size advantageous, in such a way that the smallest clear distance of the outer spiral edge of the spiral shaft to the immediately adjacent outer edge of the immediately adjacent spiral spiral spiral changed in the axial direction. Finally, the spiral shafts are rotated against each other to change the sieve deck, so that the existing between two immediately adjacent core tubes free space changes and either larger or smaller.

In practice, different configurations of the screen deck have proven to be advantageous. For example, a very small clear distance, which is hereinafter referred to as the smallest clear distance and / or as Sieblücke, between tween two immediately adjacent coils suitable for providing a large space between two immediately adjacent core tubes and according to this arrangement allows a very large passage width , so that this arrangement is usually used for the separation of elongated feed material or long parts.

By rotation of adjacent and respectively continuously in the working direction of parent spiral waves, the clear distance in the axial direction can be changed variably and adjusted to a maximum value, so that the space between immediately adjacent rotation elements is kept to a minimum. This position can be used for example for the separation of less Langge stretched material or bottles. In the aforementioned settings, it is advantageous if all the rotation elements to each other have the aforementioned positions or if all elements are arranged Rotationsele at least substantially equivalent or in the same way to each other. An adjustment of the screen deck or a change in the positions of the spiral waves, in particular via rotation of the spiral waves, is also referred to as setting the rotation angle offset. This allows a changed position of Spiral waves from one to the next, relative to each other, each in the same way influencing the Klassierverhaltens.

A disadvantage of the aforementioned device for separating is that for changing the screen deck or for rotation of the rotation elements with each other, in particular for changing the Sieblücke or passage width between two adjacent rotation elements, each of the connecting means of Antriebsein direction must be solved. The spiral waves are interconnected with at least one connecting means, in particular a dome roller chain. In practice, two directly adjacent rotation elements are usually connected via a dome roller chain, so that acts on the end-side rotation elements ei ne dome roller chain and the central rotary elements which are bordered between the end-side rotation elements attack two dome roller chains. The drive device and the connecting means are arranged in the gear box of the spiral shafts.

Since a rotation of a spiral roll or a rotation element due to the composite and the rotational sense coupling of the rotation elements with each other causes a rotation of all other rotation elements, is to change the screen deck or to change the Sieblücke and / or the passage width - that is to adjust the clear Distance between the Wendelaußenkante and the immediately adjacent Wendelaußenkante of the immediately adjacent rotation element - a release of the aforementioned connecting means necessary. Most of all connection means or dome roller chains must be solved, or at least that roller chain, which is coupled with the element to be rotated Rotationsele. To solve or remove the dome roller chains of the gearbox is opened and the roller chains must be removed individually. This process can not be taken over by machine and requires at least one operator, who is preferably supported by another person, in particular to ensure operational and occupational safety.

After removal of the roller chains, the spiral waves can be rotated against each other and thus the desired rotation angle offset or the desired offset angle, that is, the desired passage width, can be adjusted. When setting is important to ensure that a rotation of the rotation element may be repeated several times, so that a collision of the coils of immediately adjacent Rotation elements is avoided to exclude damage to the separator. This setting requires the utmost care and precision.

Subsequently, the connection means are coupled again with the rotation elements. This reconnection takes place in a very small space, since this must be carried out in the gearbox in which ultimately the Ro tationselemente are stored. Even with the attachment of the connecting means to the rotating elements highest care is required to avoid machine damage, especially on the rotating elements and / or in the gearbox.

Both during the assembly and when removing the connecting means, the connecting means or roller chains can easily entglei th the operator th and fall into the gear housing. For this, the connection means must be recovered again - namely from a crowded for the operator situation with increased work / security risk. In addition, the connection medium can cause damage to the separator when slipping.

As can be seen from the above statements, the adjustment of the passage width between two immediately adjacent rotation elements is very time-consuming and therefore entails a longer downtime associated with it. This adjustment work takes about 5 to 8 hours and is performed by at least two people. The resulting costs, which include both personnel costs and those associated with downtime, are disproportionately high, with the result that, in the final analysis, the screen deck is only adjusted when it becomes imperative. Although a setting of the screen deck depending on the input material or the intended use would be very advantageous for each individual case, this can usually not be carried out economically under the above conditions.

DE 20 2014 105 361 U1 relates to a device for separating feed material with at least two rotary elements designed as screen rollers, which are connected to one another via a traction means of a drive device, so that at least two adjacent screen rollers have a direction of rotation coupling.

The object of the present invention is to avoid the disadvantages of the prior art or at least to substantially reduce or eliminate them. weaknesses. In particular, it is the object of the present invention to provide an on direction for separating, which ensures an adjustment of the passage width and / or the Sieblücke or a change of the screen deck on rotation of the rotating elements with each other in a simple manner.

The above object is achieved in a device for separating the ge called type at least substantially by the fact that at least one rotation element, a device, in particular provided for adjusting the rotation element, assigned, in the connected via the connecting means NEN state decoupling the direction of rotation -Coupling of at least two immedi applicable adjacent rotation elements allows.

The embodiment of the invention makes it possible that a rotation of the Ro tationselemente or adjustment of the rotation angle offset can be done without loosening the connecting means, in particular the dome roller chains and the connecting means is necessary. The device ensures that, with the connection or coupling of the rotation elements still present one another, in particular via the connection means, a rotation of the elements is made possible, rotation of a rotation element not rotating the rotation element immediately adjacent to this rotation element conditionally. According to the invention this is achieved in that the direction of rotation coupling, which is ultimately required for driving the rotation elements, can be decoupled or canceled by means of the device. It is understood that in the regular operation of the separating device, the connec tion medium is applied to the rotary member or coupled with this, that it causes a common rotation of the rotation elements when driven by the drive means. The device is ultimately used according to the invention, if an adjustment of the passage width or the Sieblücke, that is, an adjustment of the rotational angle offset or the clear distance between two immediately adjacent outer edges of the spiral, should be made.

According to the invention, such an adjustment or variation of the position of the Ro tationselemente be achieved in the screen deck with a significantly lower cost and associated with significantly lower operating costs compared to the prior art, so that use of the separator is much more economical, especially where a change in the screen deck to change the fractions to be classified more economically and frequently can be performed so that the flexibility of the separator can be significantly increased overall. The screen deck according to the invention or the inven tion proper separation device can be targeted and purpose-adapted to be classified to the feedstock.

The time required to rotate the rotary elements or to change the positions of the rotating elements to each other in the screen deck is made possible with egg nem compared to the prior art by up to 90% reduced expenditure of time. In addition, the safety at work is increased, since an insertion and removal of the connecting means in the very cramped gearbox begehäuse and concomitantly a predicament of the change durchfüh-generating operator is avoided or is not required.

According to the economy of change of the screen deck of the separator can be increased by up to 80% compared to the prior art, so that a screen deck adapted to the feed material target and Zweckge is used.

A rotation of the rotation elements can be guaranteed in the range of 0 to 100 ° (angular degree), it should be ensured during a rotation of a rotating element that no stop takes place on the immediately adjacent Rotationsele element and thus machine damage can be avoided.

After rotation or adjustment of the rotation elements, the device, in particular mounted on the rotation element, is preferably designed such that it again enables the rotation-sense coupling of the at least two adjacent rotation elements.

In a particularly preferred embodiment of the present invention, at least one drive means is arranged on the rotation element. Preferably, the drive means is designed as a gear. If a plurality of rotation elements is provided, then two Antriebsmit tel are provided at the central rotation elements, which are arranged between tween the outer rotation elements, while on the outer rotation elements only a drive means is provided. The drive means is to be arranged and on acquisition of the drive means corresponding to the connecting means out forms. The arrangement or coupling of the connecting means with the drive means or the composite of the drive means to the connecting means may be formed in such a way that on the drive means a torque transmission to drive the rotation element is ensured, wherein the drive means itself via the connecting means and thus on the drive device is formed drivable from. If the connecting means as a roller chain and the drive means is designed as a gear, an arrangement of the roller chain to the gear so that engage in the teeth of the gear in the openings of the roller chain, so that the spaces between the teeth of the drive means for the arrangement of the chain links serve the roller chain or the connecting means.

To drive the rotary member via the drive means, the Antriebsmit tel can be connected torsionally rigid with the rotary member. The connection of the drive means to the rotation element and, concomitantly, the connection of the connection means to the rotation element can cause the sense of rotation coupling of at least two immediately adjacent rotation elements.

Furthermore, the device is preferably designed such that the rotationally rigid connection of the drive means to the rotation element is detachable. A release of the torsionally rigid connection of the drive means to the rotation element be the decoupling of the sense of rotation coupling of at least two immediately adjacent rotational elements, since at a no longer existing torsionally rigid connection of the drive means to the rotation element rotation of the rotation tion element tion no rotation of the drive means and concomitantly causes no rotation of the connected via the connecting means immediately neigh disclosed rotating element. In addition, the drive means can also rotate when there is no longer a torsionally rigid connection to the rotation element, ie ultimately when the direction of rotation of at least two indirectly adjacent rotation elements is uncoupled, independently of the rotation element. However, such rotation is not required according to the invention for Variegated tion of the positions of the rotation elements and thus not to ensure different passage widths between two immediately adjacent rotation elements. The rotation element may accordingly be rotatable relative to the drive means and the connection means. Such relative rotation of the rotary member to the drive means and the connecting means enables adjustment of the arrangement of the rotary members the screen deck without solution of the connecting means, which can connect directly adjacent rotary elements together.

It is particularly advantageous if in each case a device according to the invention is arranged on a majority of the rotating elements of the screen deck, preferably at all, to, where it has proven to be particularly advantageous for adjusting or rotation of the rotating elements, if the device provided on all rotation elements is. In particular, upon rotation of the Rotationselemen tes a fixed position of the drive means are ensured by the fact that the drive means is further connected via the connecting means, which in particular is tensioned, with the immediately adjacent rotary member.

In addition, it is provided in a further preferred embodiment of the inven tion thought that the rotation element has a core tube and, in particular helically extending around the core tube, one or more pieces formed helix. Furthermore, the rotation element preferably egg nen, in particular fixedly connected to the core tube, bearing pin. The La gerzapfen may be provided for the arrangement of the drive means and the device, wherein the device and the drive means may be mounted on the journal. Accordingly, the rotation element is particularly preferably designed as a worm shaft, also called spiral shaft or spiral roller. By means of the helix, a delivery of the transported goods in the conveying direction, that is, at least substantially transversely to the axis of rotation of the rotating elements, can be promoted, wherein a fraction can also be carried away below the screen deck formed by the rotary elements. In addition, a white tere fraction in the direction of the axes of rotation, that is transversely to the conveying direction Rich promoted. A change in the fractions to be deposited can take place by rotation of the rotation elements relative to one another, in which case the free space present between two immediately adjacent rotation elements or the sieve size or passage width existing there can change. The passage width characterizes in particular the separation grain size, that is, the size that determines the separation of the feed material and characterizes which particles can be deposited below the sieve deck. The larger the passage width, the greater the separation grain size is formed and, accordingly, the larger are those particles or those constituents of the feed material which are deposited below the screen deck. According to a preferred embodiment of the inventive concept, the device has a first adjustment means. The first adjusting means may be formed as a gear disc and / or has a radial locking teeth. The first adjusting means is in particular connected to the drive means, a fixed and / or frictional and / or positive, particularly preferably torsionally stiff, connection being provided.

In addition, the first adjusting means can also be arranged and / or stored on the bearing journal. The first adjusting means may further be torsionally rigid with the rotary member, in particular with the bearing pin, connectable. The torsionally rigid connection of the first adjustment means with the rotation element can be lifted by the device, in particular for decoupling the direction of rotation coupling. Since the first adjustment means can be fixedly connected to the drive means, the decoupling of the directional coupling by the device means that the first adjustment means is decoupled together with the drive means from the rotation element such that a relative movement of the rotation element is possible to the first adjusting means as well as to the drive means and concomitantly to the connecting means can be made possible. The Antriebsmit tel can optionally be rotated together with the first adjustment means relative to the rotary member, which, however, does not have to be Runaway when rotating the rotation elements to ensure an altered passage width.

The toothed wheel disk or the first adjustment means can serve to set the rotation of the rotation element, wherein markings can be present on the first adjustment means which can mark initial values or "zero values". In the direction of rotation coupling is ensured by means of the first adjustment means that both the device and the drive means can be rotatably connected onselement with the Rotati. The first adjusting means accordingly serves both for coupling and for decoupling the drive means with the Rotati onselement and thus allows both the direction of rotation coupling and the decoupling of the sense of rotation. As a result, a relative rotatability of the rotary element can be carried out independently of the respective elements of rotation directly adjacent to the rotary element.

In this context, it is particularly preferred if the Verstelleinrich device has a second adjustment. The second adjusting means may be formed as a flange disc. In addition, the second adjusting means with the Be connected rotary element. Particularly preferably, the second Verstellmit tel is connected to the journal, in such a way that a firm and / or frictional and / or positive, preferably torsionally rigid, connection is ensured to the bearing pin or to the rotary member.

From the above statements it follows that the second adjusting means can be mounted on the bearing journal. In addition, the second adjusting means is also arranged on the first adjusting means, wherein, however, upon decoupling of the sense of rotation, a relative movement of the second adjusting means to the first adjusting means can be ensured. Consequently, the second adjusting means can rotate together with the rotary member for rotation of the rotary member and for SET ment of the rotation angle offset. The first adjusting means, however, does not rotate with a decoupled direction of rotation of at least two immediately neigh th rotation elements with the rotation element, so that the second adjusting means and the first adjusting means are shifted from each other or rotated relative to each other. By marking on the first adjusting means and / or on the second adjusting means, it can be displayed to the operating personnel how far the spiral roller has already rotated in comparison to its initial state or how far a rotation is still possible without damaging the rotating element or the immediately adjacent Rotationsele Mentes.

Preferably, an engagement means for engaging in the first adjustment means on the second adjustment means is arranged and / or stored. The intervention means is associated in particular with the device. In this case, the engagement means may be formed as a pawl, wherein it prevents the relative movement of the first adjusting means to the second Ver adjusting means in the locked state or when engaging in the first adjusting means and accordingly a torsionally rigid connection of the Antriebsmit means and the first adjusting means to the rotary member and especially the bearing pin guaranteed. To decouple or cancel the rotation sense coupling between two immediately adjacent rotation elements, the engagement means is to be released from the first adjustment means so that it is only arranged or connected to the second adjustment means. The engagement means may be connected to the second adjustment means via at least one tension spring or optionally a plurality of, in particular redundant, tension springs. In addition, the engagement means may be formed such that it in the latched to stand in the space that results between two immediately adjacent teeth of the first adjustment, can intervene. Accordingly, the intervention a latching lug for engagement between the teeth of the first adjusting means, which is formed in particular at the edge or on the peripheral edge as a gear wheel, have. About the tensioned state of the spring is the A handle means in the locked state firmly connected to the first adjustment means, so that the first adjusting means and the at least one drive means are torsionally rigid or -fest connected to the rotary member. To decouple the direction of rotation coupling, the latching lug of the engagement means is released from the clearance between the teeth of the first adjustment means, so that the blockage is canceled and relative rotation of the first adjusting means and the second adjusting means and in particular the second adjusting means relative to the first adjusting means he allows becomes. To ensure a permanent arrangement of the means Eingriffsmit on the second adjustment means, the engaging means via a, in particular form-fitting, securing to the first and / or the second adjusting means, in particular form-fitting, be connected. Optionally, this fuse of the engaging means can be canceled in the case of a desired decoupling of the rotational groove, with the tension springs optionally additionally serving for clamping the engagement means or the detent nose into the first adjusting means. By the engagement of the latching lug in the latching toothing of the first adjusting means, a very fine adjustment of the rotation of the spiral roller can take place. Through the gear disc or by the first adjustment medium, in particular a four times finer setting than in comparison to a one-inch roller chain can be done.

The toothed wheel disk or the first adjusting means can have a bearing sleeve, in particular wherein the bearing sleeve or the spacer sleeve ensures the distance to the bearing unit of the rotary element, which is likewise mounted on the bearing journal. The pawl disk or the first adjusting means can be designed such that on the first ratchet disk, the drive means or the drive means, in particular a double-toothed chain, is arranged, so that for decoupling the direction of rotation coupling this first adjusting means and thus one Also, the drive means is decoupled from the bearing pin or is decoupled, but still stored on the journal and / or is ordered to. Furthermore, at the first adjusting means a groove with feather key is arranged, which in the latched state or locked state by the handle means ensures the torsionally rigid connection of the first adjustment means and thus also the drive means to the bearing pin and the Rotationsele element. Furthermore, a securing ring, also referred to as a Nutenring or Seeger ring, is preferably arranged on the shaft journal and on the second adjusting means, so that an axial securing of the bearing pin as well as of the second adjusting means can be ensured.

In a further preferred embodiment of the invention, the first Ver adjusting means and the second adjusting means are arranged coaxially with each other. The co-axiality of the first adjusting means to the second adjusting means is realized in that both adjusting means are arranged on the bearing journal. In this case, the rotation of the rotary member can be ensured by means of the relative movement of the first adjustment by means of the second adjustment.

According to a preferred embodiment of the inventive concept, the helices of immediately adjacent rotation elements interlock. In particular, it is provided that the radial distance from the outer edge of the spiral to the immedi applicable to the outer edge of the spiral adjacent core tube is greater than 1 mm out forms. In particular, the distance is in a range between 2 and 30 mm. Accordingly, the distance of immediately adjacent core tubes on the web height of the coils and the distance from the outer edge of the spiral results to the core tube, that is ultimately the web height plus a few millimeters. Preference, all rotary elements have at least substantially equal web height.

A change in the screen deck or a change in position of the spiral rollers can be made such that - as previously explained - the slightest light Ab was immediately adjacent spirals on the device made changeable out forms. In particular, the aforementioned distance is designed to be adjustable. Thus, by the different arrangement of the coils to each other under different passage widths between two immediately adjacent core tubes allows and, consequently, a separation grain size can be specified. At a very small clearance - in the axial direction - between the coils results in a very large passage width, while resulting in the largest clearance a very small passage width. The smallest clear spacing of the coils not only influences the passage width or the separation grain size, but also that fraction or fractions which are / are deposited transversely or in the direction of the rotational axis. By rotating the rotation elements relative to one another, a different process result or a different classification result can be made possible. Depending on the feed material can accordingly a Adjustment of the classification result and the fractions to be separated can be ensured flexibly.

In a further preferred embodiment, a third adjustment means is provided instead of the engagement means or optionally in addition to this. The third adjusting means is designed in particular as a chain lock and / or double roller chain and can enable the relative movement, in particular the Dre hung, the second adjusting means to the first adjusting means. In this case, the third adjusting means may be formed as a chain lock and / or duplex roller chain circulating around the first and the second adjusting means. A setting can, for example, with an accuracy of one inch, with Lich the set size is determined by the chain links of the chain lock ge guaranteed. Although the setting on the chain lock is not as fine as about the setting by means of the first adjusting means and the engagement means, however, allows the third adjustment a robust and durable and ver schleißunanfällige adjustment or rotation of the rotary member. The chain lock can be arranged on gears of the first and second adjusting means, so that there is a chain around the first and the second adjustment to running chain lock. Accordingly, via the third adjusting means, an adjustment of the phase offset by means of gears and a chain can be done, where in this setting can be seen in analogy to a clutch. In particular special, therefore, as previously explained, the first and the second adjustment medium formed as gears and / or have an outer locking teeth, which is designed to engage in the free spaces of the duplex roller chain. The outer detent toothing of the first and second adjusting means may be formed at least substantially the same.

Preferably, the third adjusting means encloses more than 50%, preferably more than 60%, more preferably from 50% to 90% and in particular at least substantially 70% to 80% of the outer diameter of the first and / or the second adjusting means. For latching and / or clamping, a tensioning means, in particular a tension spring, can be arranged on the third adjusting means. For relative rotation of the first adjusting means to the second adjusting means, the tension spring and then the third adjusting means can be released next. For re-latching first the chain lock or the double roller chain - that is, so the third adjustment means - um umt to the first and the second Verstellmit tel and then xed by the clamping means in the locked state fi. According to a further embodiment of the invention, the first Verstellmit tel is designed as a perforated disc. The perforated disc may have a plurality of openings or holes. Furthermore, a fitting or a filler may be provided for engagement in the first adjustment medium. The fitting can be formed corresponding to the openings of the perforated disc and / or provided for engagement in the first adjustment medium. The engagement of the shaped piece in the first adjusting means may allow a frictional and / or positive, in particular special torsionally rigid, connection of the first adjusting means to the second adjusting means. When solving or removal of the fitting, a re lative movement of the second adjusting means to the first adjusting means and, consequently, a decoupling of the rotational sense coupling ensures who the. The first adjustment medium may surround the bearing journal circumferentially or be stored on or on the journal. In addition, the shaped piece is preferably arranged on the second adjusting means and firmly connected thereto. The composite of the molding to the second adjustment means may be formed form liquid and / or friction. Ultimately, the setting on the interaction of a perforated disc and a recess for engagement in the perforated disc NEN shaped piece provides an adjustability of the rotary element, wherein a rotational sense decoupling for relative movement of the rotary member or the two th adjusting means to the first adjusting means or see provided to the drive means. A statement about the device can be made again by the handle of the shaped piece in the perforated disc, so that the torsionally stiff connec tion can be ensured for driving the rotary member via the drive means and, consequently, via the drive means and the connecting means. This compound is both wear-resistant and durable and designed vibration-resistant.

The rotation elements may be arranged such that they form a flat or curved screen deck. The choice between a flat or a vault th sieve deck can follow it depending on the purpose and the feed. A domed screen deck is particularly suitable if the ongrowing material is to remain longer above the screen deck. The combination between a plane and a curved screen deck can be used depending on the purpose purposefully according to the process conditions.

According to the invention, the rotation elements can be rotatably mounted on one side and / or on both sides in a flattening. The use of a one-sided or one two-sided bracket results depending on the purpose of the separator. In a one-sided support is advantageous that a separation into at least two fractions can take place, in a fraction below the screen deck, in ei ne fraction in the conveying direction, that is transverse to the axes of rotation, and a fraction in the direction of the axes of rotation. A two-sided storage can produce a high stability of the screen deck, allow the classification of feed material with a very high weight and be designed safely against overload or Überbean spruchung, so that a machine break can be safely avoided.

Furthermore, the drive device may have at least one motor. The Mo tor can be arranged on at least one journal of a rotary element is attached. In addition, the rotation elements can be designed to be drivable with the same, in particular synchronous, angular velocity or rotational speed via the drive device. A transmission of the torque takes place starting from the engine via the connecting means and the drive means to the respective rotation elements, wherein the rotation elements are interconnected. Incidentally, preferably the spiral pitch of, and in particular all Rota tion elements per 360 ° at least substantially equal, so that a gleichförmi ger spiral shape of the helix can be ensured to the core tube.

According to a further aspect of the present invention, a method for adjusting at least one rotation element and / or for rotating the rotation elements against each other and / or each other is provided. The method uses in particular a device for separating feed material, as has been characterized in one of the aforementioned embodiments. The Rota tion elements can be driven by a drive device and are connected to each other via connecting means, which are in particular out as a roller chain, the drive means connected to each other. To drive the Rota tion elements a sense of rotation coupling immediately adjacent Rotationsele elements is provided. The method is characterized in that for Variegated tion of the passage width and / or the separation grain size and / or the smallest clear distance between coils of immediately adjacent Rotationsele elements and / or rotation of the spiral rollers with each other, that is ultimately to adjust at least one rotation element, a decoupling of the rotational sense coupling of the at least two immediately adjacent rotation elements is performed via a device, so that the rotation elements can be adjusted.

Essential to the invention here is that when adjusting the rotation elements no rotation sense coupling to the immediately adjacent rotation elements prevails or is present, so that the rotation element can be moved relative to the connecting means be, with a rotation or movement of the rotation element no movement or rotation of the Conditioner conditionally. In a preferred embodiment of the method, it is provided that all rotation elements of the separation device are repeatedly and / or adjusted in several procedural rensschritten so that when adjusting the rotation elements, a collision of the coils of immediately adjacent rotation elements can be avoided. Accordingly, an altered screen deck can be adjusted.
