    专利说明:

    The invention relates to a conveyor system, comprising two spaced-apart running frame profiles, a plurality arranged therebetween, motorized conveyor rollers, a running along the at least one frame profile insulator with a plurality of longitudinally open receptacles for conductors and a plurality of arranged in the insulator conductor, which with a drive electronics of Conveyor rollers are electrically connected, wherein in each case one conductor is mounted in a respective receptacle.
    Such a conveyor system is known in principle. In this case, the current conductors form a power supply and / or data bus which can be contacted in order to tap electrical energy and / or data signals between a power supply or a controller for the motor rollers.
    For example, EP 0 300 128 A1 discloses a roller conveyor track in which rectangular rectangular busbars are embedded edgewise in lateral cheeks. At certain points, the said conductor rails are guided to the surface of the lateral cheeks. There, the motor rollers can be supplied with electrical energy via electrical contacts which touch the conductor rails.
    A disadvantage of this arrangement is that the motor rollers can be mounted only at certain positions, namely where the conductor rails are guided to the surface of the lateral cheeks.
    Furthermore, it is disadvantageous that curved courses of the conveyor track, increases in the same, as well as helical courses (rising, curved courses) of the conveyor track with the system used in EP 0 300 128 A1 can only be realized with difficulty.
    An object of the invention is therefore to provide an improved conveyor system. In particular, even more complex progressions of the conveyor track should be easy to implement and the motor rollers should be flexible.
    The object of the invention is achieved with a conveyor system of the type mentioned above, in which the form factor f of a current conductor, which is defined as the quotient of the circumference of a surface equivalent to the cross section of the conductor and the circumference of the said cross section of the conductor, in the range of f = 0.88 up to f = 1.00.
    In this way, even more complex progressions of the conveyor track, that is, in particular curved courses, ascents and helical courses, are easily realizable, since the current conductors have essentially the same bending behavior in all directions. In particular, the moment of resistance in the x-direction and y-direction is equal or approximately equal. In addition, the motor rollers are flexible because the conductors can be contacted virtually throughout their course. It makes sense in this context also to produce the insulator of an easily bendable material. In particular, it is advantageous if the insulator is made of PVC-U and / or consists of a material having a modulus of elasticity of about 2900 N / mm 2.
    Further advantageous embodiments and modifications of the invention will become apparent from the dependent claims and from the description in conjunction with the figures. It is advantageous if the cross section of a conductor is polygonal, in particular regularly polygonal. In particular, the cross section of a conductor can thus be rectangular but also approximately square, square, hexagonal or octagonal. It is favorable if the cross-section of a conductor is oval, in particular circular. In particular, the cross section of a conductor can thus be oval but also approximately circular or circular.
    It is advantageous if the electrical connection to the drive electronics of the conveyor rollers by means of resilient and unilaterally resting on the conductors contacts. As a result, simply constructed contacts for the electrical contacting of the drive electronics can be used. In particular, these contacts can be arranged in a special, separate from the conveyor roller connection box. The connection box can also contain the named drive electronics. The latter can also be arranged directly in the conveyor roller.
    It is furthermore advantageous if the electrical connection of a plurality of sections of conductors takes place with the aid of resilient contacts encompassing the conductors. In this way, the contact resistance can be kept small, and comparatively large currents can be conducted via the said contacts. It is particularly advantageous in this context, if each conductor is provided a plurality of resilient and punctiform, linear or flat resting contacts. By using a plurality of contacts lying one behind the other in the longitudinal direction of the conductors, the contacting still succeeds if unevenness occurs in the laying of the conductor or if the power supply bus is laid in an arc shape, e.g. in a curve of the conveyor track.
    In this context, it is particularly advantageous if the contacts each have a plurality of contact tongues running transversely to the conductor and spaced from each other in the longitudinal direction. As a result, the current transfer resistance can be reduced because the contact tongues can compensate unevenness well and act electrically like individual contacts connected in parallel.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals and the same component names, the disclosures contained throughout the description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position. Furthermore, individual features or combinations of features from the illustrated and described different embodiments may represent for themselves, inventive or inventive solutions. All statements on ranges of values in the description of the present invention should be understood to include any and all sub-ranges thereof, e.g. is the statement 1 to 10 to be understood that all sub-areas, starting from the lower limit 1 and the upper limit 10 are included, ie. all subregions begin with a lower limit of 1 or greater and end at an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1 or 5.5 to 10.
    Fig. 1 shows an exemplary section of a conveyor system 1 obliquely from above. The conveyor for transporting objects (e.g., containers, trays, cartons) comprises two spaced-apart frame sections 2 and 3 and a plurality of motorized conveyor rollers 4 therebetween. Via belts 5 further non-motorized conveyor rollers 6 and 7 may be driven. Of course, it is not a mandatory condition that all conveyor rollers of the conveyor system 1 are driven directly or indirectly, but it can also idle rollers between the frame sections 2 and 3 may be arranged. It would also be conceivable that a conveyor belt or belt is placed over the conveyor rollers 4, 6, 7. In particular, the motorized conveyor roller 4 can be arranged at the end of the conveyor belt or belt, since the wrap angle of the belt or the belt is large there. The motorized conveyor roller 4 thus forms a drive roller. A separate belt 5 may be using a belt or
    Belts omitted. Thus, a conveying surface for objects is not formed by the motorized conveying roller 4, but by an upper run of the conveyor belt or belt.
    Furthermore, the conveyor 1 includes optional guide rails 8 and 9 which are mounted on mounting bracket 10 to the frame sections 2 and 3. These serve for better lateral guidance of the objects conveyed on the conveyor 1, e.g. Containers, trays and cardboard.
    The motorized conveyor rollers 4 are connected via connection boxes 11 to a power supply bus and a data bus. The control of the conveyor rollers 4 via the controller 12. For the detection of conveyed objects in the course of the frame profiles 2 and 3 and photodetectors 13 may be arranged. Opposite reflectors 14 are additionally arranged in this example.
    Fig. 2 shows the conveyor system 1 already shown in Fig. 1 now obliquely from behind, Fig. 3 obliquely from below. In addition, in FIG. 3, the power supply bus 15 laid internally on the frame profile 2 can also be seen.
    FIG. 4 now shows a detail of the conveyor system 1, specifically the frame profile 2 with the energy supply bus 15 arranged thereon, a connection box 11 and a connection cable 16 which connects different sections of the energy supply bus 15 with one another. For this purpose, 16 plugs 17 and 18 are arranged on the connecting cable, which can be inserted into the connection boxes 11. In FIG. 4 it can also be seen that the power supply bus 15 comprises an insulator 19 running along the frame profile 2 with a plurality of longitudinally open receptacles in which a plurality of current conductors 20 are arranged, one power conductor 20 each being mounted in a respective receptacle. About the connection boxes 11, the current conductors 20 are electrically connected to a drive electronics of the conveyor rollers 4. Depending on each (motorized) conveyor roller 4 each a connection box 11 is provided, and each connection box 11 is connected to the current conductor 20. It is also conceivable, of course, that a connection box 11 is provided for a plurality of conveyor rollers 4.
    Fig. 5 shows the section of the conveyor system 1 already shown in Fig. 4 now in an exploded view. It can be seen in FIG. 5 that the connection box 11 has a base plate 21 and a plug-on part 22. In addition, the power supply bus 15 can be terminated with an end cap 23.
    When constructing the conveyor system 1, therefore, the base plates 21 are first attached to / in the frame profile 2 (for example clipped in via a latching connection). Thereafter, the power supply bus 15 is mounted and contacted by attaching the Aufsteckteils 22, in particular with the drive electronics for the conveyor roller 4 (see also Figures 11 to 13). Different portions of the power supply bus 15 may be finally connected to each other by inserting a connecting cable 16.
    Fig. 6 shows the arrangement already shown in Figures 4 and 5 now in side view, Fig. 7 shows a cross section AA and Fig. 8 shows a cross section BB. In FIGS. 7 and 8, the base plate 21 protruding through the frame profile 2 and its locking connection in the frame profile 2 can be seen well. In addition, a plug 24 of a data bus is also visible, which is arranged on the frame profile 2 on the outside and thus opposite the power supply bus 15 (see also FIGS. 14 and 15). In Fig. 8 also contacts 25 of the plug 18 can be seen, which are resilient and engage around the current conductors 20. Finally, a circuit board 26 arranged in the connection box 11 is also shown with an electronic circuit arranged thereon, which inter alia serves for communication with the controller 12 and the drive control of the conveyor roller 4. The current conductors 20 are constructed identically in this example. In principle, however, the use of different current conductors 20, in particular with different cross-section, conceivable.
    FIG. 9 now shows the power supply bus 15 with the connection cable 16 shown at an angle from behind, FIG. 10 shows the same arrangement in section. In FIGS. 9 and 10, it is particularly clear that the cross-section of the current conductors 20 is circular. This is by no means a mandatory condition. For example, the cross section could also be approximately square, square, hexagonal or octagonal, as well as oval (e.g., ellipsoidal) but approximately circular.
    In general, the form factor f of the current conductor 20, which is defined as the quotient of the circumference of a circle equivalent in area to the cross section of the conductor 20 and the circumference of the said cross section of the conductor 20, lies in the range from f = 0.88 to f = 1.00. If the current conductor 20 has a circular cross-section, then the form factor is f = 1.00.
    If, for example, the current conductor 20 has a square cross-section of 1 mm × 1 mm, its area A = 1 mm 2 and its circumference U = 4 mm. The diameter of the area-equivalent circle is
    Its circumference is U
    The form factor f is thus
    In particular, from FIG. 9 it can also be seen that the resilient contacts 25, which surround the current conductors 20, each have a plurality of contact tongues, which extend transversely to the conductor 20 and are spaced apart in the longitudinal direction of the conductor 20. As a result, the current transfer resistance can be reduced because the contact tongues can compensate for unevenness and act electrically like individual contacts connected in parallel. Advantageously, individual contact tongues also improve the electrical contact when the conveyor track and thus the power supply bus 15 extend arcuately.
    It is advantageous if-as can be seen in FIG. 10 -the free bending length of the contact 25 or of the contact tongues corresponds approximately to three to four times the diameter of the mentioned area-equivalent circle. This results in a good compromise between the current carrying capacity of the contact 26 and its contact force on the current conductor 20.
    FIG. 11 again shows the power supply bus 15 shown in an obliquely insulated manner from behind, but now in conjunction with a connection box 11. According to this embodiment, the drive electronics are arranged within the connection box 11 and are electrically connected to the contacts 27. The electrical connection to the drive electronics of the conveyor rollers 4 takes place here by means of contacts 27 resting resiliently on the current conductors 20 (for example, as in FIG. It is particularly advantageous if - as shown in FIG. 11 - several (in particular two) contacts 27 are provided per conductor 20, which are electrically connected within the connection box 11. For example, the contacts 27 may be made of a single copper strip. By using a plurality of contacts 27 lying one behind the other in the longitudinal direction of the current conductors 20, the contacting still succeeds if unevennesses occur in the laying of the conductor 20 or if the power supply bus 15 is laid in an arc shape, e.g. in a curve of the conveyor track.
    FIGS. 12 and 13 show the connection box 11 in detail (FIG. 12 in section, FIG. 13 in front view). Good to see in Fig. 12, in particular the resiliently resting on the conductors 20 contacts 27. For the upper contact 27 shown in FIG. 12, two positions are shown, once the unloaded and once occupied when placed on the conductor 20 Position.
    The contacts 27 shown in FIGS. 11 to 13 lie linearly on the current conductors 20. It would also be conceivable, of course, that these point or flat rest on this.
    14 now shows a detail of the conveyor system 1 already shown in FIGS. 1 to 3, wherein the guide rail 8 has been omitted and additionally the data bus 28 and the wiring 29 to the photodetector 13 are shown.
    Fig. 15 shows the arrangement of Fig. 14 now partially in exploded view. Specifically, a photodetector 13 including wiring 29 and the connector 30 mounted thereon is shown lifted. Furthermore, a segment of the data bus 28 is shown lifted off, so that well the mounted at the ends of the segment connector 24 can be seen. The plugs 24 and 30 can be connected in the projecting through the frame section 2 through part of the base plate 21 of the junction box 11. In contrast to the power supply bus 15, which connects a plurality of terminal boxes 11 uncut electrically, the data bus 28 is laid in a chain. It is also clearly visible from FIGS. 14 and 15 that a photodetector 13 is not connected to each connection box 11, but these are arranged along the conveyor system 1 as required.
    The embodiments show possible embodiments of a conveyor system 1, wherein it should be noted at this point that the invention is not limited to the specifically illustrated embodiments of the same or the same, but also various combinations of the individual embodiments are mutually possible and this variation possibility due to the teaching technical action by objective invention in the skill of working in this technical field expert. So are all conceivable embodiments, which are possible by combinations of individual details of the illustrated and described embodiment variant, includes the scope of protection.
    In particular, it is noted that the conveyor system 1 may in reality also comprise more or fewer components than illustrated.
    For the sake of order, it should finally be pointed out that, for a better understanding of the construction of the conveyor system 1, this or its components have been shown partly unevenly and / or enlarged and / or reduced in size.
    The task underlying the independent inventive solutions can be taken from the description.
