Description

The invention relates to a transport drum for products of the tobacco processing industry having the features of the preamble of claim 1.

Transport drums for products of the tobacco processing industry are used in various embodiments to continuously transport the products during the manufacturing process in a facility. Basically, the transport drums are distinguished in transverse axial and longitudinal axial promotional drums, which are driven by a drive means to a rotary motion and having a plurality of acted upon by vacuum troughs. In transaxially conveying transport drums the products are conveyed away transversely to the longitudinal axis of the products, so that the troughs during the transport movement perform a movement transverse to its longitudinal extent. In longitudinally conveying conveying drums, the products are conveyed away substantially in the longitudinal direction of the products and taken over in a transfer point of a queraxial conveying roll off. A longitudinal axial abfördernde transport drum is provided, for example, to take over the strand-fed products, which are cut in a previous step to a predetermined length. Such a longitudinal axial conveying transport drum is also referred to as "spider" due to the conveying movement and the arrangement of the lever arms. Queraxial promotional transport drums are eg in the transport from the longitudinal axial promotional transport drum used until the delivery of the products, wherein one of the queraxial promotional transport drum can also be designed as a laser drum on which the products are rotated during the rotary motion in addition to its own longitudinal axis and are guided past a fixed, pulsating laser.

The troughs themselves are attached to fixed or movable lever arms or receptacles depending on the transfer and transfer points to be realized. Fixed or movable lever arms must be provided in particular if the products are to be taken over or transferred or generally guided in a transfer or transfer point which is at a distance from the transport drum.

To transfer the products, the negative pressure in the transferring troughs of the transport drum is briefly reduced by a controller, thus increasing the pressure, and at the same time generating a negative pressure in the receiving troughs of a second transport drum, so that the products by the effective pressure difference between the pressure in the taking over and sucking the vomit troughs.

So that the transfer of the products takes place without errors even at the high conveying speeds and the effective pressure difference for the transfer of the products can be chosen as low as possible, the troughs in the transfer or transfer points must be moved with a very high positional accuracy to each other along a predetermined space curve. Because of these high demands, the lever arms are very expensive items for themselves, which also in the case of moving lever arms must be elaborately performed and mounted. The production of the wells themselves represents a special cost factor because they have to be produced with a particularly high dimensional accuracy.

Another problem to be solved by such transport drums is that, due to their fixed geometries, the troughs are only suitable for transporting products of specific dimensions, such that the lever arms on the transport drums, when changing product to products of other geometry, against lever arms with troughs of a different geometry must be replaced in total. The replacement of the lever arms is in addition to the cost of the lever arms themselves is a further cost factor and is also time consuming and requires considerable technical expertise of the person mounting. In particular, it may be necessary to disassemble, in addition to the lever arms, additional parts of the transport drums which are e.g. form the leadership of the lever arms.

From the EP 1 733 635 B1 already a transport drum is known, are provided on the pivotable lever segments, on each of which the troughs are arranged. The lever segments are pivotally mounted about a pivot axis extending parallel to the longitudinal axis of the transport drum. The troughs on the lever segments are arranged such that the longitudinal axes of the troughs are aligned parallel to the pivot axes of the lever segments and to the longitudinal axis of the transport drum. During the revolving rotation of the transport drum, the lever segments are rotated about their longitudinal axis, whereby the pitch, ie the distances of the troughs in the circumferential direction of the transport drum, can be dimensioned differently at different angles of the circumference of the transport drum. The lever segments themselves are relatively short in the radial direction and point at their radially outer surface each interchangeable trough body, which are obviously fastened by means of a fastening means not described in detail radially from the outside.

The object of the invention is to provide a generic transport drum, which can be converted with the least possible effort and cost of products with a different geometry without disadvantages to the above-described, exactly complied movement.

The object is achieved by a transport drum with the features of claim 1. Further preferred embodiments of the invention are described in the subclaims, the figures and the associated description.

According to the basic idea of the invention, it is proposed that a guide be provided on the lever arms, which allows an arrangement of the replaceable troughs on the lever arms in exclusively a predetermined fastening position. Due to the intended guidance of the exchange troughs, the troughs for a product change can be exchanged separately as individual parts for other troughs with a different geometry, without having to exchange the lever arms as a whole. Furthermore, it can be ensured at the same time by the provided guidance that the troughs are positioned despite the constructive interface with a very high positional accuracy to the transport drum or on the lever arms and indeed only in the predetermined attachment position. In addition, can be simplified by the guide, the attachment of the recessed bodies so far that the person to be mounted moves the recessed bins automatically by the proposed guide when pushed onto the lever arms in the intended target position. Further, by the proposed leadership a defined, the position of the recesses predetermining surface created, which can be produced by a special processing with a very high dimensional accuracy, without the lever arm has to be processed in total. The guide forms in addition to the specification of the desired position of the exchange troughs also an anti-rotation of the exchange troughs during operation of the transport drum. Since only the interchangeable troughs have to be exchanged for retooling the transport drum due to the solution according to the invention, the costly and time-consuming disassembly of the lever arms, especially in the area of structurally complex connection to the transport drum, is eliminated. Furthermore, the proposed leadership of the removable troughs can be used simultaneously to seal the removable troughs with respect to the lever arms.

It is also proposed that the recessed grips are pushed by the guide in one direction only on the lever arms. By the predetermined direction of Aufschiebebewegung the assembly can be further simplified by the desired position of the recessed grips can be found during assembly easier by the predetermined Aufschieberichtung. This is particularly advantageous if a plurality of replaceable troughs to be changed in a row, since the assembly process to be handled can be simplified and faster due to the exercise and repetitive similar movement.

It is also proposed that the replaceable troughs are secured against loosening from the fastening position by means of a securing part. By securing part can be prevented that the removable troughs automatically loosen after assembly again.

A particularly easy to manufacture embodiment of the guide can be realized by the guide is formed by at least two mutually arranged at an angle guide surfaces on the lever arms and the interchangeable recesses, wherein the guide surfaces extend to the interchangeable troughs parallel to the longitudinal direction of the troughs. The angled guide surfaces define the angular orientation of the interchangeable recesses with respect to the longitudinal direction of the troughs, in which the interchangeable recesses are then slid and secured along the guide surfaces.

In this case, the securing part can preferably be formed by a frontally held on the lever arms backup plate, which overlaps the removable troughs in the mounting position on an end face. Due to the proposed design and arrangement of the security part, the replaceable troughs can be secured solely by a clamping connection to the lever arms, so that a special mounting flange or a mounting hole in the replaceable troughs are not required. It is particularly advantageous that the surfaces of the provided on the recesses troughs for attachment must not be changed constructively.

It is also proposed that the securing plate is shaped in such a way that it can be moved by a rotary movement from a first mounting position which does not overlap the exchangeable recess into a second fastening position which overlaps the replaceable recess on the end side. The proposed solution, the replaceable tray can be replaced without the backup plate must be solved by the lever arm. The backup plate must instead for disassembly of the replaceable troughs only from the mounting position to the mounting position and after pushing the replaceable troughs in the mounting position be moved back.

It is also proposed that the replaceable troughs are secured against rotation by a guide pin spaced from the guide pin. Due to the created anti-rotation can be ensured that the replaceable troughs maintain their desired position during the rotation of the transport drum, which can be stiffened by the spaced arrangement and a corresponding dimensioning of the distance, the entire connection of the replaceable troughs.

It is further proposed that passage openings are provided in the replaceable troughs, which are arranged such that they are fluidly connected in the fastening position of the replaceable troughs with pressure medium lines in the lever arms.

In a further preferred embodiment of the invention, the guide comprises at least one of a surface of the lever arm and / or the removable recess projecting pin, which engages in a guide contour on the respective other part. By means of the pin, the replaceable troughs can additionally be connected to the lever arms at least as far as a certain path of the pushing-on movement in such a way that the direction of the further pushing-on movement is additionally defined by the guide contour starting from this path. Thereby, e.g. prevented by a clumsy mounting movement lose contact with the guide or the guide surfaces and thereby tilt to the lever arms.

In this case, the guide contour may preferably have a constriction, in which the pin is locked in a latching manner. By locking the pin can be a kind of backup fuse the replaceable trough are realized on the lever arm, to which the actual attachment of the replaceable trough connects via the securing part.

It is further proposed that the lever arms are held at one end to the transport drum, and the recessed bodies are arranged on the free protruding from the transport drum ends of the lever arms. Such an arrangement of the recesses offers, for example, for transport drums in which the longitudinal direction of the troughs are aligned parallel to the axis of rotation of the transport drum, as e.g. in cross-axially conveying transport drums or laser drums is the case. The held on the transport drum ends of the lever arms are preferably used to control the movement of the lever arms, the attachment of the lever arms and the fluid pressure fluid connections to the provided in the transport drums pressure medium lines.

The replaceable troughs can be aligned in the mounting position advantageously parallel to the free ends of the lever arms, as is the case with transversely conveying promotional drums, or be aligned perpendicular to the free ends of the lever arms, as is the case with längsaxial promotional transport drums.

It is further proposed that the guide is formed by a shape-coded recess. The shape-coded recess may be formed, for example, by a recess with an edge surface which has a shape adapted to the outer contour of a section of the recesses, so that the recessed grips can be inserted into the recess and positioned on the lever arms only in a predefined orientation. The shape of the recess thereby forms an encoding, by the reverse, a mounting with a wrong orientation of the recessed can be prevented.

It is also proposed that the interchangeable troughs are formed by elongated hollow bodies, on the outside of which the troughs are arranged in the longitudinal direction. The formation of the replaceable troughs as a hollow body offers the advantage that the cavity provided in the replaceable troughs can be used on the one hand as forwarding the pressure medium and on the other hand also for fastening the replaceable troughs.

In this case, the guides may preferably be designed as pipe pieces, on which the replaceable troughs are attachable. The pipe sections can be used in addition to the guide at the same time as a pressure medium line through which the wells can be subjected to negative pressure in the replaceable troughs.

It is also proposed that the interchangeable recesses have at least two recesses of different geometry and can be fastened to the lever arms by the guide in a number of fixing positions corresponding to the number of recesses. The troughs for receiving the products can be particularly easily replaced by troughs with a different geometry by the removable troughs are solved and fixed in a different orientation, in which another trough of the same exchange but other geometry is arranged in the desired position.

In this case, the interchangeable troughs may be at least in the section adjacent to the lever arms in cross-section to its longitudinal extent preferably point-symmetrical and / or axisymmetric, so that the interchangeable troughs by rotating 180 degrees about its longitudinal axis in a second orientation can be fixed, in which a second arranged on the exchange trough is positioned with a different geometry in the desired position for transfer or takeover of the products. The troughs, which are not in the fixed position of the exchange troughs respectively in the intended for takeover and / or transfer of the products target position, are inactive and fluidically not connected to the pressure medium system, ie in this case can not be acted upon with negative pressure.

In the FIG. 1 is a driven in the direction of arrow C to a rotary transport drum in the form of a Längsaxialförderers 1 (also referred to as a spider) to recognize the front side a plurality of rotating during the rotary motion lever arms 4 are arranged. At the lever arms 4 each exchange troughs 5 are provided, which will be described later in more detail. The lever arms 4 are rotatably mounted on the Längsaxialförderer 1 and perform even during the rotational movement of the Längsaxialförderers 1 a rotational movement to this, so that the arranged thereon exchange troughs 5 during the rotational movement of the Längsaxialförderers 1 have a constant horizontal orientation and rotate on an elliptical orbit. The longitudinal conveyor 1 are fed in a horizontal direction two parallel strands of cut to a predetermined length products 3 on a format base 2. Furthermore, two lever arms 6 of a second transport drum can be seen, which in the FIG. 2 is shown in more detail as Queraxialförderer 7.

The products 3 are supplied on the Formatgrund 2 continuously and linearly and in a transfer point I of the in the FIG. 8 Troughs 25 and 26 of the replaceable troughs 5 shown in more detail by a negative pressure generated in the troughs 25 and 26. During the further rotational movement of the longitudinal axial conveyor 1, the products 3 held in the hollows 25 and 26 are transported clockwise to a transfer point II where they are also subjected to negative pressure, in which FIG. 3 to be recognized troughs 42 of the lever arms 6 of Queraxialförderers 7 taken.

In the FIG. 2 is another illustration of the same arrangement FIG. 1 in the direction of the trained as Queraxialförderer 7 transport drum with a in the transport direction E subsequent second transport drum also in the form of a Queraxialförderers 8 to recognize. The longitudinal axial conveyor 1 can be seen in this view from the side. Due to the high transport speeds of the products 3 and taking place in the transfer point II change the transport direction by 90 degrees, the lever arms 4 and 6 with the arranged thereon exchange troughs 5 and 9 with an extremely high positional accuracy along a given space curve must be performed. This is particularly necessary because the guided in the takeover and transfer points I and II at a distance from the transport drums lever arms 4 and 6 and at a distance guided exchange troughs 5 and 9 a movement corresponding to one by the movement of the lever arms 4 and 6 run defined spatial curve, during which the lever arms 4 and 6 in the transfer point II must also have a predefined orientation to each other, which must be complied with for a fault-free transfer of the products in each case.

The troughs 42 and 25 and 26 on the lever arms 4 and 6 according to the invention counter to many years of practice each interchangeable interchangeable troughs 9 and 5 formed, which a quick and structurally easy to handle change of the troughs 25,26 and 42 to another geometry, i. allow for hollows with a different radius and / or a different length.

The guides can be formed by surfaces produced in a separate operation that are particularly precisely produced, by means of which the disadvantage of the extended tolerance chain can be compensated so far that the depressions 25, 26 and 42 can nevertheless be moved within the permissible tolerance range of the given space curve. The surfaces forming the leadership can be produced and / or reworked, for example, by a special processing step and should be manufactured to the required shape and position tolerances.

In the FIGS. 3 to 6 the lever arm 6 of the Queraxialförderers 7 and the interchangeable trough 9 are enlarged as individual parts and assembled to recognize from different directions. On the lever arm 6 three guide surfaces 13 and 14 are provided, wherein the parallel to the guide surface 14 provided rear guide surface is not provided with a reference numeral. The guide surfaces 13 and 14 are aligned at an angle of 90 degrees to each other and parallel to the free end 6a of the lever arm. In the guide surface 13 a plurality of openings 15 are provided provided in the lever arm 6 pressure medium lines. Further, each side of the guide surface 13, two protruding pin 11 and provided on the front side of the lever arm 6 a securing member 10 in the form of a fastened via a screw locking plate. The swap body 9 also has three guide surfaces, which are formed by a flat base surface 17 and two webs 18 and 43 extending perpendicular to the base surface and longitudinally parallel. The webs 18 and 43 are in their distance from each other and in alignment with the base 17 aligned and arranged so that they are substantially free of play on the guide surfaces 13, 14 and the rear in the Figure 5 not to be recognized guide surface to the plant.

In the projecting from the base 17 webs 18 and 43 each have a number of pins 11 corresponding number of guide contours 12 are provided, in which the pins 11 during the Aufschiebebewegung engage, so that the removable trough 9 when pushed by the guide contours 12 additionally is forced into the predetermined target position. The Aufschiebebewegung the removable trough 9 is finally limited by a stop 16. In addition, the removable trough 9 can be additionally secured provisionally by a locking of the pin 11 in an end position in the guide contour 12. After reaching the attachment position, the removable trough 9 is secured on the lever arm 6 by the securing member 10 from the in the Figures 3 and 5 to be recognized mounting position in the clockwise direction in the in the FIG. 4 twisted to be recognized mounting position. The securing part 10 is provided with such a shaped outer contour that in the mounting position, as in the FIG. 5 can be seen, the guide surfaces 13 and 14 releases the front side and in the mounting position, the webs 18 and 43, as in the FIG. 4 can be seen, overlapping the front side.

By means of the attachment described, the replaceable trough 9 can be secured solely by clamping forces on the lever arm 6, without the need for fastening bores and to be found during assembly.

In the FIGS. 7 and 8th is an embodiment of a arranged on a lever arm 4 of the Längsaxialförderers 1 removable trough 5 can be seen, which has two aligned perpendicular to the axis of rotation of the Längsaxialförderers 1 wells 25 and 26, in which the supplied on the Formatgrund 2 products 3 are received in the takeover point I. The lever arms 4 protrude at the end face parallel to the axis of rotation of the Längsaxialförderers 1 from this, and are themselves rotatably mounted on the Längsaxialförderer 1, so that the arranged thereon exchange troughs 5 during the rotational movement of the Längsaxialförderers 1 have a consistent horizontal orientation. The leadership of the recessed troughs 5 is in this embodiment formed by a clamping pin 20 which is insertable into an opening 44 of the lever arm 4 and secured by a locking member 10 designed as a clamping ring. In addition, the guide comprises a radially projecting from the lever arm 4 arm 21 with an end disposed thereon guide pin 22 which engages in the mounting position in a receptacle 23 on the removable trough 5. In addition to its guiding function, the guide pin 22 also acts as an anti-rotation device for the replaceable trough 5, so that the replaceable trough 5 subsequently maintains the predetermined desired position. In addition, by the second connection point created by the guide pin 22, the natural vibration behavior of the exchange trough 25 can be positively influenced by stiffening the entire connection.

In the FIGS. 9, 10 and 11 is an alternative embodiment of a lever arm 27 of a longitudinal axial conveyor 1 with two alternating recesses 28 and 29 arranged thereon. The exchangeable hollows 28 and 29 are, as in the FIG. 11 can be seen, each formed as a hollow body and each have a arranged on its outer side trough 39 and 40. The interchangeable recesses 28 and 29 each include a first portion 37 having a larger outer and inner diameter and a second portion 38 having a smaller outer and inner diameter. Further, a radially outwardly projecting flange 36 is provided with a non-round, in this case oval outer shape and a mounting opening 46 for a securing part 10 in the form of a screw on the edge of the first portion 37. In addition, a respectively opening into the wells 40 and 39 bore 41 is provided, which is connected to generate the negative pressure in the wells 39 and 40 fluidly through the cavity in the recesses 28 and 29 with a pressure medium system in the transport drum.

The lever arm 27 is formed in this embodiment by an extension piece with two parallel protruding pipe sections 33 and 34, which include a projecting shoulder 32 centrally between them. By the above paragraph 32 laterally two guide surfaces 32a and 32b are formed, which adjoin the contact surfaces 30 and 31. The inventively provided guide for positioning the replaceable troughs 28 and 29 is formed in this case by the pipe sections 33 and 34, to which the interchangeable recesses 28 and 29 are plugged, and which at the same time a fluidic connection between the troughs 39 and 40 and the pressure medium system in the Create transport drum. Further, the guide comprises the lateral guide surfaces 32a and 32b, which allow due to the non-circular shape of the flanges 36, an orientation of the interchangeable recesses 28 and 29 in only one angular position to the lever arm 27. As a result, it can be ensured despite the two-part design of the lever arm 27 and the interchangeable recesses 28 and 29 that the interchangeable recesses 28 and 29 are in the intended orientation after attachment. The cavity in the replaceable troughs is therefore used on the one hand to guide the interchangeable recesses 28 and 29 and on the other hand to the fluidic connection of the bore 41 with the pressure medium system.

The non-circular design of the flanges 35 and 36 represents a shape coding, by means of which the interchangeable recesses 28 and 29 can be fixed in only one position. A faulty installation can be practically ruled out.

In the FIG. 12 is a further preferred embodiment of a removable trough 47 to recognize, on the two opposite Troughs 48 and 49 are provided with a different radius. The troughs 48 and 49 are arranged axially symmetrical to the vertical axis H and / or arranged point-symmetrical to the center P, so that the exchange trough 47 must be rotated to change the product 3 receiving troughs only 180 degrees and fixed in the twisted position, so that the troughs 48 or 49 in the transfer position have a different geometry.
