    The invention relates to a conveyor roller with an axis and a cylindrical rotatable about this axis mounted cylindrical roller body. Furthermore, the invention also relates to an arrangement comprising a conveyor roller of the type mentioned. Finally, the invention also relates to a conveyor for transporting objects, in particular loading aids, such as containers, trays, by means of conveyor rollers in several conveyor sections, with a first frame profile, a second frame profile, wherein the first and second frame profile at a mutual distance paral¬lel to each other and in the conveying direction of the objects and each have a vertical profile web with these in the conveying direction behind one another arranged recesses for receiving an axis of the conveyor rollers, a first conveyor section, in which the conveyor rollers are arranged with their axes substantially normal to the profile web between the first and second Rah¬menprofil, a second conveyor section, in which the conveyor rollers with their axes at an angle to the profile web between the first and second frame profile At least one motorized conveyor roller in the second conveyor section, at least one pivot bearing in the second conveyor section, which supports the motorized conveyor roller at one end with its axis, comprising a one-piece or multi-part main body and a pivot plate which is rotatably mounted on the main body in a receptacle about a pivot axis, which comprises a recess oriented normally on said pivot axis and which is normal to said pivot axis
    Has pivot axis standing guide surfaces, wherein the pivot bearing is mounted with its base body via a releasable fastening device on the frame profile.
    A conveying roller for obliquely installing the same in a conveyor is basically known. In a conveyor system, usually a large number of such conveyor rollers are installed, of which at least some are motor-driven and thus provide for the propulsion of the objects to be transported on the conveyor system. In general, the roller axes are aligned normal to the main conveying direction. In special applications, however, it may be necessary to align the roller axes obliquely to the conveying direction, for example, when the conveyed objects are to be aligned at a stop arranged laterally along the conveyor system or at a guide arranged laterally along the conveyor system. The inclined conveyor rollers move the conveyed objects to said stop or guide, but the stop / guide ensures that the objects do not fall off the conveyor but continue to be transported further in the main conveying direction.
    In conventional conveyor systems, the construction of such conveyor sections with inclined conveyor rollers is comparatively difficult, since special conveyor rollers and / or frame profiles are used there, which in particular are of the length of the conveyor rollers which are suitable for straight installation ¬hen are different. Subsequent retooling of an existing conveyor system on inclined conveyor rollers or dismantling on straight conveyor rollers is therefore difficult. At least the respective Rollenund / or frame profiles must be procured or different Rol- len / frame profiles are kept in stock.
    A further disadvantage of the known solutions is also that the prior art cradles are not flexible in use. These often have a predetermined inclination of the axle receptacle for the conveyor roller or are constructed comparatively fragile. For example, FP 1 999 195 R1 discloses rlcmi pin Rpienipl wplnhpQ with mphrprpn Rtiftpn πρΙρπργϊ i <t
    But play in the bearings can lead to unwanted vibration phenomena in the drive train.
    An object of the invention is therefore to provide an improved conveyor roller and an improved arrangement thereof and an improved conveyor system. In particular, the use of the relevant components should be made more flexible. This means in particular that one and the same conveyor roller suitable for straight and oblique installation and also the pivot bearing should be flexible replaceable. The latter should also effect a possibly rigid storage of the conveyor roller.
    The object of the invention is achieved with a conveyor roller of the type mentioned above, wherein at least a first end of the axle in the part projecting above the roller body has a first shoulder between a roller-side first section with a larger first cross-section and one relative to the first paragraph Having opposite second section having a smaller second cross-section.
    Furthermore, the object of the invention is also achieved with an arrangement comprising a pivot bearing and a conveying roller of the type mentioned above.
    Finally, the object of the invention is also achieved by a conveyor system of the type mentioned, in which the first frame profile and second frame profile in the first Förderab¬ section and second conveyor section are formed similar, and the base above and below the pivot plate sowienormal to the pivot axis running a first side wall part and second side wall part forms, which limit the receptacle, wherein the Schwenk¬ plate mounted within the receptacle on the first side wall part and second Seitenwand¬ part (backlash or low backlash) and against the stationary base about the pivot axis is rotatably disposed, and the pivot bearing with his Base body is mounted on the vertical profile web of at least the first frame profile via the detachable fastening device and is positioned relative to the first frame profile such that the
    Axis of the motorized conveyor roller extends through both of the recesses in the vertical profiled member and the recess in the pivot plate.
    In this way, the conveyor roller can be used with its first axis end in a flexibly adjustable pivot bearing, whereby an inclination of the conveyor roller in almost any angular positions (in particular -10 ° to 0 ° and 0 ° to 10 °) is made possible, in particular continuously. In the pivot bearing, this skew is made possible by the pivot plate. Advantageously, such and the same pivot bearing can be used for different inclinations of a conveyor roller, whereby the storage for the construction, modification and operation of a conveyor system is greatly simplified.
    The proposed measures, moreover, a torque between the conveyor roller and pivot bearings are well transferred, and the conveyor roller is relatively rigidly fixed even at oblique installation in the conveyor system. Vibration phenomena, which under certain circumstances could be caused or intensified by a motor control for the conveyor roller, are thereby effectively avoided or at least occur only in a weakened form.
    Through the two sections on the axle end of the reel body and the conveyor roller can be used flexibly by the first paragraph between the first and second section for oblique installation and the second paragraph is provided on the first section for the straight installation of the conveyor roller. Advantageously, one and the same conveyor roller can thus be used for different mounting positions, whereby storage for the construction, modification and operation of a conveyor system is likewise greatly simplified. In particular, the conveyor roller can also have an internal motor for driving the roller body, so that objects (for example containers, trays, cardboard boxes, etc.) can be actively forwarded even on system sections with inclined conveyor rollers.
    Further advantageous embodiments and modifications of the invention will become apparent from the subclaims and from the description in Zusammenschaumit the figures. It is advantageous if the first section of the conveyor roller can be inserted in a form-fitting manner into a first-hexagonal recess of a first frame profile and the second section is cylindrical. As a result, the conveyor rollers can be used with their first axle end non-rotatably in second frame profiles of a conveyor system having second hexagonal recesses. It has proved to be particularly advantageous in this case if the hexagonal recess (s) is / are designed with a wrench size SW = 11 mm, since this size corresponds to a qua¬si standard for conveyor systems.
    It is advantageous if the first section of the conveyor roller has a square shape or a four-armed star shape. In this way, even a positive fit between the first portion and a first hexagonal recess can be made even if the perimeter / inscribed circle of the square or star shape is smaller than the perimeter / inscribed circle of the first hexagonal recess. It is also favorable if the second section of the conveyor roller has a thread. As a result, the conveyor roller can be fixed with a nut in the conveyor.
    Moreover, it is advantageous if the second end of the axle in the part protruding beyond the roller body has a third section which can be inserted into a second hexagonal recess of a second frame profile and has a hexagonal-shaped third cross-section. As a result, the conveyor rollers can also be inserted non-rotatably with their second axle end into second frame profiles of a conveyor system which have second hexagonal recesses. Again, it has proved to be particularly advantageous if the second hexagonal recess is designed with a key width SW = 11 mm, since this size corresponds to a quasi-standard for conveyors.
    In this context, it is particularly advantageous if the third section is mounted so as to be axially displaceable, in particular resilient, relative to the first and second sections. In this way, it is possible to first insert the conveyor roller with the first or second section into a first recess in a first frame profile of a conveyor and then insert it into a second frame in a second frame profile by pressing the third section. The conveyor roller can thus be installed in principle without tools in a conveyor system or be removed from this again. Of course, this conveyor roller can also be additionally fixed, beispiels¬weise with screws.
    It is also particularly advantageous if the conveyor roller comprises a fourth section of circular cross-section adjacent to the first section roller side, which is smaller than the circumference of said hexagon. As a result, the cylindrical section of the roller axis lying essentially in the interior of the roller body, on which, for example, a rolling bearing, a stator of an electric motor, a bushing and the like can be arranged, is kept comparatively thin. The material removal for the production of the first to third section starting from a bar material therefore falls low. The processing time is thus short, while the service life of the processing tools is long. It has proven to be particularly advantageous in this context if the fourth section has a diameter of 12 mm. It is also favorable if the arrangement comprising a conveyor roller according to the invention and a pivot bearing comprises two frame profiles spaced apart from one another, wherein a first recess in a first frame profile with the first section of the conveyor roller and a second recess in the second frame profile with the third section the Förderrolle korrespon¬diert. In this variant, the conveyor roller can thus be used between two frame profileseiner conveyor system, in particular with non-rotatable bezie¬high as fixed axis.
    It is advantageous if the first recess and / or the second recess is hexagonal. As a result, conveyor rollers with a hexagonal axle end can be used, or with an axle end which can be inserted at least into the hexagonal recess. In this case, it has once again turned out to be particularly advantageous if the hexagonal recess is designed with a key width SW = 11 mm, since this size corresponds to a quasi-standard for conveyors.
    It is particularly advantageous if the first frame profile has a plurality of first recesses spaced apart in its longitudinal direction and the second frame profile has a plurality of second recesses spaced apart from one another in the longitudinal direction, one first recess each directly opposite a second recess, the distance between the first and the second frame profile is so dimensioned that the first section and the third section of the axle come to lie in gegehradem installation of the conveyor roller in directly opposite first and second recesses of the frame profiles and the longitudinal distance of the first or second Ausnehmun¬gen dimensioned in that, when the conveyor roller is mounted obliquely, the first section of the axle is mounted in a first recess of the first frame profile, the second section of the axle in the cylindrical recess of the pivot bearing mounted externally on the first frame profile in the first recess, in particular in the pivot plate of a pivot bearing, and the third portion of the Achsein one of the first recess obliquely opposite second Ausneh- come to rest in the second frame profile.
    In this embodiment, therefore, the length of the conveyor roller or the distances between the first and third as well as between the second and third section are matched with the spacing of the two frame profiles and the spacing of the recesses arranged in them. The conveyor roller can thus be placed just between the frame profiles as well as installed diagonally between them. If the conveyor roller is being installed, the first and third sections of the conveyor roller come to lie in the recesses of the frame profiles, the second section correspondingly projects beyond the first frame profile. If this is equipped with a thread, the conveying roller can be screwed to the first frame profile, for example. In this case, a special nut can be used, which makes it possible for the first section of the conveyor roller to project out of the frame profile. The nut has for this purpose a frame profile facing cavity (e.g., a cylindrical bore) in which the first portion is received. The cavity can thus be executed as a cylindrical and the thread of the nut upstream recess.
    In particular, if the difference in the cross sections of the first and fourth sections of the conveyor roller is small and thus the first shoulder or bundle between these two sections is only small, a washer may also be provided between this first shoulder / collar and the frame profile. This is preferably relatively large area and made of steel. In order to prevent tearing of the recess in the frame profile, which is usually made of aluminum, prevented.
    If the conveyor roller is installed at an angle, then the second section of the conveyor roller is inserted into a corresponding recess in the pivot bearing, the outer frame profile is mounted in the region of a first recess. The first and the second recess used are then no longer directly opposite each other, but are offset from each other slightly obliquely. The fact that the second section of the conveyor roller, which is used in oblique installation in the pivot bearing, slightly outwardly than the first section of the conveyor roller, the length compensation required for the oblique installation can follow good. By means of a displaceably and in particular resiliently mounted third section and / or by omitting a washer which is intended for straight installation, length compensation in the case of oblique installation of the conveyor roller, in particular a motorized conveyor roller, can also be assisted or effected. In order to facilitate the oblique installation of the conveyor roller or to prevent jamming of the connection between the conveyor roller and the frame profiles, sufficient play should be provided between the recesses in the frame profiles and the first and third sections of the conveyor roller. It is favorable in the conveyor system when the guide surfaces normally standing on the pivot axis correspond with guide surfaces in the base body which are also normally normal to the pivot axis, and a torque acting on the pivot plate about the axis of the conveyor roller from the contacting guide surfaces of the pivot plate and the guide surfaces of the base body is recorded.
    In this case, the guide surfaces of the swivel plate already touch the guide surfaces of the main body in the unloaded state, that is, without applying a torque to the swivel plate. A torque between the conveyor roller and pivot bearing is therefore transmitted via the guide surfaces of the Schwenkplat¬te and the guide surfaces of the body. The storage of the conveyor roller is thus particularly rigid. Vibration phenomena that could be caused or amplified under circumstances of a motor control for the conveyor roller are thereby more effectively avoided or at least appear very attenuated. By the proposed measures, the pivot bearing of the pivot plate can also be performed relatively "fragile" (thin-walled), which results in a total of the pivot bearing a comparatively compact structure, without underneath the stability suffers. The pivot bearing can in this case also have a bearing clearance and can thus be easily manufactured. It is also favorable in the conveyor system, if the pivot plate has at least one normally protruding from the guide surface cylindrical pivot and the body is made in several parts, wherein in a first Teiline first storage for receiving said pivot pin is arranged or in a first part, a first half-shell and in a second part, a second half-shell for receiving said pivot pin is arranged. This results in a comparatively compact construction of the pivot bearing. This can be mounted by simply joining the parts of the body. By the pivot also results in a good pivotal mounting of the pivot plate. Of course, the pivot receptacle does not have to be formed by two half-shells, but another (bearing) receptacle can also be used.
    If a dividing plane of the base body through the bearing bore for receiving the said pivot pin laid so that in each of the parts a half-shell is formed, by appropriate design / dimensioning of the pivot and the half-shells, the pivot plate on the Drehzap fen / half-shell arrangement " play "held in the body or be stored. An acting on the pivot plate about the axis of the recess Dreh¬moment can be taken in this case on the pivot / half-shell assembly. If wear phenomena occur during operation of the conveyor system on the pivot / half-shell arrangement, it would be possible, however, for a torque acting on the pivoting plate about the axis of the recess to be absorbed by the guide surfaces of the pivoting plate and guide surfaces of the base body.
    It is particularly favorable when the pivot plate has two pivots of the type mentioned, which are mounted in two bearings or two half shells each. In this way, the pivot plate is even more rotatably mounted. It is advantageous if the pivot plate is substantially cuboid. In die¬se manner, the pivot plate can be easily prepared, for example by these cut from a flat material and equipped with a recess for the axial end of a conveyor roller and optionally with at least one Drehzap¬fen or at least one bore for a pivot pin. The pivots can, for example in Holes be inserted in the pivot plate.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures. Show it

    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component designations, wherein the disclosures contained in the entire description apply mutatis mutandis to the same parts with the same reference numerals. same component names can be transferred. Also, the location information chosen in the description, such as up, down, laterally, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis in a position change. Furthermore, individual features or combinations of features from the illustrated and described different exemplary embodiments may also represent separate, inventive or inventive solutions.
    Figures 1 and 2 show an exemplary cylindrical conveyor roller 1 for transporting objects in an oblique view (Fig. 1 from the front, Fig. 2 from the back). The conveyor roller 1 comprises a fixed axle 2 and a roller body 3 rotatably mounted about this axle 2. A first end of the axle 2 has in the part projecting beyond the roller body 3 a first shoulder 4 between a first section 5 lying on the roller side with a larger first cross section and a second section 6 opposite thereto with a smaller second cross section.
    The second end of the axle 2 has in this example in the projecting beyond the Rollenkör¬per 3 part on a third section 7 with a hexagonal third cross section. In Fig. 1, a fourth section 8 is shown in broken lines, wel¬ which adjacent to the first section 5 and in this example also adjacent to the third section 7 is arranged. The fourth section 8 forms the part of the axle 2, which generally runs within the roller body 3. In general, the axle 2 can be continuous or divided, as shown in FIG.
    Moreover, the conveying roller 1 shown in Figs. 1 and 2 comprises a protective cap 9 in which a connecting cable 11 is guided, which is connected inside the roller body 3 to a motor (not shown). In addition, in the. 1 shows a washer 10. Finally, the figures also show grooves 12 in the reel body 3, in which a drive belt can be received so as to transmit the driving force from a motor driven conveyor roller 1 to motorless conveyor rollers.
    Fig. 3 shows a frame profile 13 of a conveyor system for transporting objects with a built-in conveyor roller 1 in side view. The first section 5 of the conveyor roller 1 is positively inserted into a first hexagonal recess 14 in a vertical profile web 37 of the first frame profile 13. Concretely, the first portion 5 has a square shape. An alternative form would be, for example, a four-armed star shape. Due to the selected shape, the conveyor rollers 1 can be used with their first axis end non-rotatably in the frame profile 13. It has proven to be particularly advantageous if the first hexagonal recess 14 is designed with a key width SW = 11 mm, since this size corresponds to a quasi-standard for conveyors.
    Another advantage of the square shape is that the circumference / inscribed circle of the square shape (or the four-armed star shape) is smaller than the circumference / inscribed circle of the first hexagonal recess 14. The first section 5 of the axis 2 can therefore be made relatively thin. In particular, the conveyor roller 1 may have a fourth section 8 with a circular cross-section, which is smaller than the circumference of said hexagon. As a result, the cylindrical, predominantly in the interior of the reel body 3 extending fourth section 8 of the roller shaft 2, on which, for example, roller bearings, a stator of an electric motor, bushings and the like can be arranged, are kept comparatively thin. The stock removal for producing the first to third sections 5, 6, 7 from a bar stock is therefore low. The processing time is thus short, while the service life of the processing tools is long. In this context, it has proved to be particularly advantageous if the fourth section 8 has a diameter of 12 mm.
    As mentioned, the third section 7 of the conveyor roller 1 has a hexagonal third cross section, which can be positively inserted into a second hexagonal recess 17 of a second frame profile 16. It has once again turned out to be particularly advantageous if the second hexagonal recess for the third section 7 is also designed with a key width SW = 11 mm.
    FIG. 4 now shows an arrangement 15 with two spaced-apart frame profiles 13 and 16 and a conveyor roller 1 inserted between them in exploded view. The first frame profile 13 has for this purpose first recesses 14, the second frame profile 16 second recesses 17. The first and second recesses 14, 17 are provided on the vertical profile web 37 of the frame profiles 13, 16. The assembly 15 further comprises a pivot bearing 18 which has a generally cylindrical recess 20 pivotable about the pivot axis 19 of the pivot bearing 18 and oriented normal thereto, which corresponds to the second section 6 of the conveyor roller 1. That is, the conveyor roller 1 can be inserted with the second portion 6 of the axle 2 into the recess 20 of the pivot bearing 18. The second portion 6 of the conveyor roller 1 is cylindrical in this example and has an optional thread. As a result, the conveyor roller 1 can be screwed to the pivot bearing 18 with a nut 22. The pivot bearing 18 itself is attached to the outside of the first frame profile 13 on the profile web 37, insbeson¬dere with a counter-holder 21 and nuts 22.
    In an advantageous embodiment of the conveyor roller 1, the third section 7 of the conveyor roller 1 with respect to the first and second sections 5, 6 axially displaceable, in particular resilient, mounted. In this way, it is possible to use the conveyor roller 1 first with the first section 5 and second section 6 in the first recess 14 in the first frame section 13 and then by pressing the third section 7 into the second recess 17 in the second frame profile 16 (or vice versa). The conveyor roller 1 can therefore basically be installed without tools in a conveyor system or removed from the latter. Of course, this conveyor roller 1 as shown in FIG. 4 can also be additionally fixed with a nut 22. The form closure between the first portion 5 and the first recess 14, between the third portion 7 and the second recess 17, is very helpful since the nut 22 does not need to be held against when tightened.
    The conveyor roller 1 is now mounted with its first axis end on the flexible adjustable pivot bearing 18 on the first frame section 13 and with its second Achsendedirekt in the second frame section 16 such that almost any inclinations (in particular -10 ° to 0 ° and 0 ° to 10 ° ) of the conveyor roller 1 can be achieved.
    Of course, the conveyor roller 1 with the help of the pivot bearing 18 also be installed straight. In this case, the washer 10 can be dispensed with. However, for straight installation, the first section 5 is preferably inserted into the first recess 14 and the third section 7 into the second recess 17, without a pivot bearing 18 being used for this purpose.
    5 shows a first conveyor section 38 of a conveyor system in plan view, in which one or more conveyor roller (s) 1 is or is installed between two frame profiles 13 and 16.
    FIG. 6 also shows a second conveying section 39 of a conveyor system in a horizontal section, in which at least one conveying roller 1 is installed obliquely between two frame profiles 13 and 16 with the aid of the pivoting blade 18. It can also be seen in FIG. 6 that the second section 6 corresponds to the recess 20 in the pivot plate 25 of the pivot bearing 18. In particular, the first paragraph 4 abuts on the right side of the pivot plate 25 and is pulled against it by the nut 22. In FIG. 6, the left end face of the conveyor roller 1 or the protective cap 9 is due to the strong inclination erstest frame profile 13. In principle, however, air between the Förderrol¬le 1 and the first frame profile 13 may be 13, in particular at a lower inclined position. Finally, FIG. 6 also shows the second shoulder 26 between the first section 5 and the fourth section 8 of the axle 2.
    Fig. 7 shows the pivot bearing 18 used in Fig. 6 now isolated in Explosi¬onsdarstellung. The pivot bearing 18 comprises a base body, which in die¬sem example, the two parts 23, 24 comprises, and a (here substantially qua¬derförmige) pivot plate 25, which in the base body respectively in a receptacle 40 of the same about a pivot axis 19 rotatable is stored. The pivoting plate 25 has a generally cylindrical recess 20, which is aligned perpendicular to the pivot axis 19, and guide surfaces 27, which are perpendicular to the pivot axis 19. The guide surfaces 27 correspond with guide surfaces 28 in the base body 23, which are likewise perpendicular to the pivot axis 19. 24, which are bounded by a first side wall portion 41 and ei¬nem second side wall portion 42.
    In this example, the pivot plate 25 includes coaxial with the Schwenkach¬se 19 extending and normal from the guide surfaces 27 outstanding Zylind¬rische pivot 29, which are mounted in the multi-part running body 23, 24. In the first part 23 to two first half-shells 30 and in the second part 24, two second half-shells 31 for receiving said pivots 29 are arranged. This results in a comparatively compact construction of the pivot bearing 18, which can be constructed by simply joining the two parts 23, 24 together.
    If a clearance between the guide surfaces 27 and the guide surfaces 28 is provided constructively (even if only slightly), then a torque acting on the pivot plate 25 about the axis of the recess 20 is received by the pivots 29 or their bearings 30, 31, as may be according to the embodiment of FIG. 7. For this purpose, the trunnions 29 are mounted "free of play" in the half-shells 30, 31. This can be accomplished in particular by the fact that the half-shells 30, 31 are less deep than the diameter of the pivot pins 29. If the parts 23, 24 are connected together, for example by a releasable connection device, such as the counter-holder 21 and the nuts 22, the pivot plate 25 is "play-free" (hence no play) held / stored or the pivot pin 29 between the parts 23, 24 slightly biased.
    Fig. 8 shows an alternative embodiment of a pivot bearing 18 which is similar to the pivot bearing 18 shown in Fig. 7. However, the dividing plane between parts 23 and 24 is different. Therefore, two separate screws 32, 33 are used for the assembly of the pivot bearing 18, whereas the pivot bearing 18 can be assembled from the Fig. 7 in principle alone with the aid of the counterpart 21 and the nuts 22. Advantageously, the pivot bearing 18 of Fig. 8 can thus be pre-assembled prior to installation on / in the frame profile 13. Due to the now different verlaufenden part plane instead of the half-shells 30, 31 now bearing receptacles 34, 35 are provided for the pivot pin 29, which are each completely contained in one of the parts 23,24 of the body. For the same reason half shells 36 are now provided for the counter-holder 21.
    Advantageously, a torque acting on the pivot plate 25 about the axis of the conveyor roller 1 is picked up by the contacting guide surfaces 27 of the pivot plate 25 and the guide surfaces 28 of the base body 23, 24.
    The guide surfaces 27 of the pivot plate 25 touch the guide surfaces 28 of the base body 23, 24 in this case already in the unloaded state, that is, without applying a torque to the pivot plate 25. This can be accomplished, for example, by the fact that the pivot plate 25 clearance in the designated receptacle 40th in the base body 23, 24 is fitted (Fig. 7) or provided for the pivot plate 25, groove-like Aufnahmeab¬schnitte in the parts 23, 24 in total less deep than the pivot plate 25 hochsind. In this way, the guide surfaces 27 of the pivot plate 25 and the guide surfaces 28 of the main body 23, 24 when tightening the screws 32, 33 pressed together (see Fig. 8). Of course, however, a play between the guide surfaces 27 and the guide surfaces 28 may also be provided both in the pivot bearing 18 shown in Fig. 8.
    If there is constructive (albeit slight) clearance between the pivots 29 and the bearings 34, 35, then a torque acting on the pivot plate 25 about the axis of the recess 20 will be produced by the contacting guide surfaces 27 of the pivot plate 25 and the guide surfaces 28 of the base body 23, 24, as may be the embodiment of FIG. 8. For this purpose, the trunnions 29 are mounted in the bearing receptacles 34, 35 "with little play" (therefore with a slight play). This can be accomplished in particular by the fact that the bearing receivers 34, 35 (if only slightly) are larger than the diameter of the pivot pins 29. If the parts 23, 24 connected to each other, for example, by a releasable connection device, such as the screws 32, 33, the pivot plate 25 is held on the Führungsflä¬ 27 between the parts 23, 24 "play" (therefore without play) bzw.die Pan plate 25 slightly biased.
    Due to the "play-free" mounting / mounting of the pivot plate 25 in the base body 23, 24 and in a plane perpendicular to the axis of the recess 20, a torque acting around the axis of the recess 20, which is exerted by the motorized or driven conveyor roller 1, also becomes Verdre¬hung the pivot plate 25 relative to the base body 23, 24 in the plane perpendicular to the axis of the recess 20 avoided.
    The torque transmission is generally relatively rigid, especially when this takes place via the comparatively large guide surfaces 27, 28. oscillating
    Phenomena which could be caused or intensified, for example, by too soft storage of the conveyor roller 1 by a motor control for the drive motor of the conveyor roller 1, therefore do not occur or at least only in an attenuated form.
    The two parts 23, 24 of the base body and / or the pivot plate 25 can generally consist of a metallic material, such as steel, aluminum or a sintered material. Similarly, it is conceivable that the two parts 23, 24 of the base body and / or the pivot plate 25 made of a Kunst¬, in particular a fiber-reinforced plastic. Specifically, the pivot plate 25 may be made of steel and the base 23, 24 made of plastic. Especially in this case, it may be that the bearing clearance between the / the pivot pin 29 and the half-shells 30, 31 and the Lage¬rungen 34, 35 increases over time and a torque about the axis of the conveyor roller 1, even at the beginning play-free / low-play storage of the pivot 29 is ultimately transmitted via the guide surfaces 27 and 28.
    In the examples shown, the pivot plates 25 each have two pivot pins 29. Of course, a pivot plate 25 could also have only one pivot, which is optionally made longer, to ensure a safe storage of the pivot plate 25 in the base body 23, 24.
    Also, the main body 23, 24 need not be made of multiple parts, but could also be made in one piece. In this case, instead of the pivot pins 29, for example, separate bolts can be inserted laterally through bores of the basic body into bores in the pivot plate 25, which are aligned along the pivot axis 19.
    It can be seen in FIGS. 4, 6 and 8 that the first frame profile 13 has a plurality of first recesses 14 spaced apart from one another in the longitudinal direction and the second frame profile 16 has a plurality of second recesses 17 in the profile webs 37 spaced apart from one another in the longitudinal direction thereof, wherein each first recess 14 each a second recess 17 directly gegenüberliegt.Fig. 8 shows a simplified illustration in which only a few second recesses 17 are shown by the second frame profile 16. Advantageously, the arrangement 15 fulfills the following criteria: the distance "a" between the first and second frame profile 13, 16 is dimensioned such that the first section 5 and the third section 7 of the axis 2 are directly mounted on the conveyor roller 1 second recesses 14, 17 of the frame profiles 13, 16 come to rest (with the second section 6 correspondingly projecting beyond the first frame profile 13) and the longitudinal spacing "b" of the first and second recesses 14, 17 is dimensioned such that the first Section 5 of the axis 2 beizrägem installation of the conveyor roller 1 in a first recess 14 of the first frame profile 13, the second portion 6 of the axis 2 in the cylindrical recess 20 of the first recess 14 outside of the first frame profile 13 mounted pivot bearing 18, in particular in the Swivel plate 25 of the pivot bearing 18, and the third portion 7 of the axis 2 in one of the first recess 14 schr g opposite second recess 17 come to lie in the second frame profile sixteenth
    In other words, the first paragraph 4 is used between the first section 5 and the second section 6 in the oblique installation of the conveyor roller 1, in¬dem this is brought into contact with the pivot plate 25. In the case of a straight installation of the conveyor roller 1, on the other hand, the second shoulder 26 between the first section 5 and the fourth section 8 is brought into contact with the first frame profile 13, in particular with the aid of the washer 10.
    One and the same conveyor roller 1 can thus be placed just between the frame profiles 13, 16 as well as installed at an angle between them. Characterized in that said paragraphs 4, 26 are spaced on the axis 2 in the axial direction of the Förderrolle1 from each other, or in that the second portion 6 of the conveyor roller 1 is slightly farther outside than the first portion 5, the required for the oblique installation Length compensation done (comparable to the lengths "a" and "c" in Fig. 8). By the displaceable and insbeson¬dere resiliently mounted third portion 7 and / or by omitting the intended for straight installation washer 10, this can also be supported berziehungsweise effected. However, the distance "a" between the frame profiles 13 and 16 and / or the longitudinal spacing of the recesses 14 and 17 in the frame profiles 13 and 16 can remain unchanged. Also, custom manufacture of special frame profiles, as required, for example, according to EP 1 222 125 B1, is not necessary according to the embodiment of the invention.
    With the help of arranged in the second section 6 thread and a nut 22, the conveyor roller 1 can be screwed to the first frame section 13. For this purpose, a special washer 10 (preferably of steel) may be applied to the second shoulder 26 between the first section 5 and the fourth section 8 to provide for the secure transmission of the axial forces and to rip out the first recess 14 in the first To prevent frame profile 13, which is usually made of aluminum.
    As can be seen from FIGS. 4 and 6, in the illustrated example, a special nut 22 is used, which makes it possible for the first and not necessarily threaded section 5 of the conveyor roller 1 to emerge from the first frame profile 13. The nut 22 has die¬sem purpose a first frame profile 13 facing cavity by the first section 5 is received. The cavity may, for example, be designed as a cylindrical bore located upstream of the thread of the nut 22. The bore diameter is larger than the thread diameter.
    In order to allow the oblique installation of the conveyor roller 1, or to avoid jamming the connection between the conveyor roller 1 and the frame profiles 13,16, should generally sufficient play between the recesses 14,17 in the frame sections 13,16 and the first and third Section 5, 7 of the conveyor roller 1 are provided. In order to prevent wobbling of the conveyor roller 1 in spite of the aforementioned play, the third section 7 can also be designed in accordance with the present invention. This results in a play-free / low-back Aufnah¬ me the third portion 7 in the second recess 17, even if the third section 7 is slidably mounted and sprung both with straight installation of Förder¬ role 1 and with oblique installation. These measures are particularly advantageous when the conveyor roller 1 is not bolted to the second frame profile 16. Also at the third section 7, a play-free / low-backlash recording may help to avoid the above-mentioned vibration phenomena.
    In other words, results in a conveyor system for the transport of objects, in particular loading aids, such as containers, trays, by means of conveyor rollers 1in several conveyor sections 38, 39, miteinem a first frame section 13, a second frame section 16, wherein the first and second frame profile 13,16 with mutual vertical distance "a" parallel to each other and in the conveying direction of the objects and each have a vertical profile web 37 in these in the conveying direction hintererei ¬ arranged recesses 14, 17 for receiving an axis 2 of the conveyor rollers 1, a first conveying section 38, in which the conveyor rollers with their axes 2 arranged substantially normal to the profile web 37 between the first and second frame profile 13, 16, a second conveying section 39, in which the conveyor rollers 1 with their axes 2 are arranged at an angle to the profile web 37 between the first and second frame profiles 13, 16, at least one motorized conveyor roll 1 in the second conveyor section 39, at least one pivot bearing 18 in the second conveyor section 39, which supports the motorized conveyor roller 1 at one end with its axis 2, um¬fassend a one-piece or multi-part main body 23, 24 and a pivot plate 25 which on the main body 23, 24th is rotatably mounted about a pivot axis 19 in a receptacle 40, which comprises a recess 20 which is oriented normally on said pivot axis 19 and which has guide surfaces 27 normal to the pivot axis 19, the pivot bearing 18 with its base body 23, 24 passing over a releasable fastening device 22 is mounted on the frame profile 13 or its profile 37, wherein the first frame profile 13 and second frame profile 16 are formed identically in the first conveyor section 38 and the second conveyor section 39, and the base 23, 24 above and below the pivot plate 25 and normal to the pivot axis 19 running an (upper) e The first side wall portion 41 and (lower) second side wall portion 42 forms, which limit the receptacle 40, wherein the pivot plate 25 within the receptacle 40 at the (upper) first side wall portion 41 and (lower) second side wall portion 42 spielfrei or spielspielarm and against the stationary base body 23rd , 24 is arranged rotatably about the pivot axis 19, and the pivot bearing 18 is mounted with its base body 23, 24 on the detachable fastening device 22 on the vertical profile web 37 at least the first frame profile 13 and is positioned relative to the first frame profile 13, that the axis 2 of the motorized Feed roller 1 projects through both of the recesses 14 in the vertical profile web 37 and the recess 20 in the pivot plate 25.
