Frame for belt conveyors

The invention "relates to frames for belt conveyors and "specifically relates to one from bolted through with them Crossbars held together longitudinal spars geMldeton frame for belt conveyors, the longitudinal spars of which are each open in the direction of the conveying means profiles with an outer web and formed from its upper end extending away cover web are. -

Known frame constructions have U- or C-Erofile as longitudinal spar profiles, which are arranged so that their between Two side bars, bottom bars, which form the outer bars of the frame, and one side bar of each of these profiles is used as a cover bar covers the connection connections of the cross members keeping the longitudinal spar profiles at a distance, so that between "the two Longitudinal spar profiles a distance is formed. If this is a frame for plate or hinge hinges, usually

ί a sliding strip is screwed onto the deck webs to protect the ,. Side areas of the plate or hinge band β sliding to support. Z-shaped sliding strips made of plastic material are also known, with one of their outer legs each rest on a basin web of the associated longitudinal spar profile and in the area of their length adjoining front ends are screwed to this. Furthermore, it is also known in the case of hat straps or hinge straps To keep a sliding trough loosely inserted in the space between the two longitudinal spar profiles by the fact that this S is designed as a U-profile with outwardly angled side webs and with their lateral angled areas each rests on its assigned basin web of the adjacent longitudinal spar profile *

The frame construction must be evident in such designs be designed solely by dimensioning the longitudinal spar profiles and the transverse crossbars so that they do not only Weight of the conveying means of the belt conveyor device, which is not inconsiderable in the case of a plate or flat top chain can be, but also the weight of the two deflection stations for the conveyor and possibly one additional separate drive station and in particular that of the conveyed material is able to carry deformation-free. Special from the point of view of sufficient section modulus against deflection and torsion of the frame construction under load profile cross-sections are to be selected that give the entire frame structure sufficient load-bearing capacity and Convey bending and torsional rigidity. However, this adds a not inconsiderable weight to the frame structure conditional, which significantly determines the cost price of the entire belt conveyor device.

In the case of belt conveyors with elastic, flexible conveying means, a plurality of support rollers or rollers, which are arranged on axles loosely held opposite these and on which the upper run runs supported by them, are arranged between the opposing longitudinal spar profiles of the frame conveying means to be supported over its entire surface, so it has the entire frame structure of the described type with a deck webs of both each other β opposite longitudinal spar profiles overlapping up to this | covered lying sliding plate, which in the longitudinal is longitudinally bolted% spar profiles associated outer edges with these, in order to be secured against relative displacements to the longitudinal spar profiles.

Obviously, this also applies to belt conveyor devices! Versions used with elastically flexible conveying means have the same unfavorable conditions with regard to providing the required load-bearing capacity with sufficient flexural and torsional rigidity at the same time, as described above for versions with plate or hinge belts as conveying means. Not even in the last-described version can the cover plate serving as a slider plate contribute to the rigidity of the frame construction, since its fastening screws only serve to secure it against displacement relative to the frame longitudinal spars, but neither have nor can have a bond between the cover plate and the longitudinal spar profiles, especially since that Cover plate still has the degree of freedom ^: under unfavorable load conditions or if its screw holes are not carefully adapted to those of the longitudinal spar profiles in the direction normal to their cover webs or to warp.

The invention is therefore based on the object with simple

and inexpensive means while avoiding the disadvantages known frame constructions to create a possibility

Frame of the generic type made from as few individual parts as possible and, in particular, without using, experience has shown, always cost-intensive connecting elements, such as "for example Connecting bridges or connecting brackets, simply, quickly and conveniently either in the factory for fully assembled delivery or create it particularly efficiently at the place of use to be able to do this, also from profile parts that are as simple as possible and correspondingly more cost-effective cross-sectional contouring, furthermore in the interest of improving the storage and transport of these items as well as facilitating the handling of the same during construction and / or assembly despite sufficient load-bearing capacity and bending and torsional stiffness a substantial weight reduction possible and a previously unattainable universality with regard to the creation of the most varied Belt conveyor devices with a wide variety of conveyor widths and lengths and correspondingly different load capacity properties by using essentially standardized individual parts with the corresponding advantages with regard to storage of the individual parts, assembly of the same for the frame construction required in the individual application and, if necessary, dismantling or retrofitting with the ones based on it Desired! consequences for the lowering of the cost price should be guaranteed.

The invention makes this surprisingly simpler and easier economically achieved in that held together by a cross member bolted to them Longitudinal spars formed frame for belt conveyors, the longitudinal spars each as in the direction of the conveyor Open profiles are formed with an outer web and a cover web extending away from its upper end, the longitudinal strut profiles in each case at the free end of their cover web a connecting flange extending downwards away from this

have and both longitudinal spar profiles are connected to one another by means of an intermediate piece designed as a U or C profile are, both of which extend away from its central web approximately complementary to the connecting flange of the adjacent longitudinal spar profile Side and / or edge webs are each connected to this.

It can be seen that the inventive use of an inventive-specific intermediate piece in the Together with the type of connection provided by the invention with the frame longitudinal beam profiles The composite component stiffened by the cross members results, which with comparatively the same cross-sectional design with regard to Cross-sectional contouring and / or area is a multiple compared to known frame constructions increased load capacity and flexural and torsional stiffness possesses and when designed for the same resistance to the loads occurring in comparison to such conventional frame designs have a significantly smaller material cross-section of the longitudinal spar profiles can, which is known to be significant in the weight of the frame structure and thus also the cost of the entire Belt conveyor is also determined. In the context of the invention, the entire frame design can either be open, also known as a half-box profile or as a closed construction, also called a full-box profile. In addition, experience has shown that for most cases the measure according to the invention, in addition to the frames of conventional design also formed from longitudinal spar profiles and these interconnecting cross members nor to use an intermediate piece connected to both longitudinal spar profiles, by no means a conventional one compared to the total weight Frame designs need to require a higher total weight, rather often 'with the same resistance

ability characteristics versus compared to conventional Frame designs have the same resistance properties to occurring loads and even savings the total weight of the frame structure according to the invention can be achieved. Such a frame can after the Invention with the exception of the intermediate piece and any screw elements required for its connection with the neighboring ones Longitudinal spar profiles, which are available as standard parts on the market at low cost everywhere, without any other aids or additional parts, such as support bridges or connecting brackets or the like, can be installed easily, quickly and conveniently and if necessary, "for example for the purpose of retrofitting for a different application, such as insertion into a conveyor line larger conveyor width, dismantled and after replacing some functional individual parts of the belt conveyor, such as "For example the conveyor and deflection rollers for this and, if necessary, an additional drive roller, must be reassembled.

Furthermore, the invention obviously offers the desired possibility the production costs of belt conveyor devices in particular with regard to their conveyor width and / or - • To be able to influence the length of different designs also favorably that for all designs Similar frame longitudinal spar profiles can be created and kept in stock and only on the respective Conveyor design matched intermediate pieces need to be provided, of course in the same As has been the case up to now, naturally also different cross beams are provided for different conveyor widths must be.

In further appropriate training, the side bars of the intermediate piece and the associated connecting flange of the

adjacent longitudinal spar profile in each case non-positively and / or wj

be positively connected to each other. It is calibrated %

universal the possibility of such creation of the frame, construction or the assembly of the same only at the place of use opened.

In the case of a purely frictional connection of the intermediate piece with its two adjacent longitudinal rail profiles *, it can be advantageous if the side webs of the intermediate piece and the associated connecting flange of the adjacent longitudinal rail profile are each glued to one another. Pure | Applications in which, in addition to a non-positive connection §, for example, for safety reasons, a positive '■' connection is also desired, it can be recommended that the J side webs of the intermediate piece and the associated connection | flange of the adjacent longeron profile at least ^r one of a preferably mid-point or center line symmetrical depression or recess in the one part and a complementary thereto bulge in the other component v existing latching comprise both components and both construction | ä parts glued to each other, wherein depending on the structural expediency, the depression or recess in the side web of the intermediate piece or in this associated connecting flange of the adjacent longeron prof ils and in this engaging bulge in the other component, ie, the presence \ end flange of the associated longitudinal spar prof ils, or; reversed be provided in the side web of the intermediate piece | can, but then the recess or recess J ijtt associated connection flange of the adjacent longitudinal spar 1 profile is arranged. . I.

For pure form-fitting connection of opposite one another Longitudinal spar profiles and an intermediate piece arranged between them, it has proven to be particularly recommendable, if in the connecting flange of each longitudinal spar profile at least one row of through or threaded holes at a regular distance from one another and in each side web of the intermediate piece at least one row of through holes or of complementary to through holes of the associated connecting flange of the adjacent longitudinal member profile provided ßewindelbohrern provided in Raetergleicner arrangement is and adjacent longitudinal member profile connecting flanges and intermediate piece ^ side webs by means of complementary through- or threaded holes are screwed together in these one or these penetrating screw elements. These Specifically, execution enables not only an extremely cost-effective, because practically only marketable inexpensive one Standard parts using, but also particularly easy, quick and convenient to assemble and dismantle at any location Execution of a frame for belt conveyors.

If it is for reasons of achieving a suitable section modulus the profiles involved in the frame construction according to the invention should be appropriate, can the longitudinal spar profiles each at the free end of their cover web a slope to normal to the level of the conveyor Have the central longitudinal plane of the conveyor device extending connecting flange, this with. Its free End of this central longitudinal plane of the belt conveyor or but can extend away from this. Correspondingly, according to the conception of the invention, the intermediate piece is designed so that its side webs complementary to the connecting flanges of the adjacent longitudinal spar profiles. For the In most cases, however, it will be preferable if, according to an alternative development of the invention, the longitudinal »

holniprofile one at the free end of their deck web extending approximately parallel to the normal central longitudinal plane of the belt conveyor device to the plane of the conveyor exhibit. In addition, this subordinate concept of the invention brings with it the advantageous possibility to be able to use the same longitudinal spar profiles for a wide variety of frame designs, which is what the task at hand the desired universality is particularly beneficial.

Although it is in no way necessary according to the conception of the invention that in order to achieve a special Resistant frame construction, the middle piece must occupy a height-specific position, it has to be Proven to be preferred for the majority of applications if, according to a further subordinate inventive concept, the intermediate piece with the cover webs of the two Longitudinal spar profiles aligned central web and from this is arranged downwardly extending side webs. It has been shown that with such an embodiment on the one hand, there is a particularly favorable flow of forces in each of them for the resistance of the entire frame structure Profile areas and, on the other hand, the advantageous possibility of immediate Support or support of the conveying means over a particularly large area of its width, and in most cases even its total width results, which in turn gives possibilities for relatively light * because not on deflection, but practically only on train dimensioned execution of the conveying means, for example an elastically deformable conveyor belt opened. It is with the exception of any improvement of the section modulus of the overall frame construction with respect to deformation loads is irrelevant, whether at such an embodiment, the middle piece is designed as a U or C profile.

For belt conveyors with conveyors in the form of a Plate or hinge hinge, an alternative design has proven to be particularly effective, b © i of the intermediate piece as U-shaped profile and with a central web lower than the top webs of the * two longitudinal strut profiles and t is arranged upwards away from the side webs is * This namely opens up, despite the retention of the advantages achieved by the invention, especially for plate or flat top conveyor the necessary space for the linkages baw. Hinges of the panels or supporting pieces of such a conveyor between the two longitudinal spar profiles, and also this running space through the specific Design of the intermediate piece against access; is protected from the outside and at the same time a conveyor ί channel for fragments of the conveyed goods occurring during the conveying process, such as broken fragments or the like. or other impurities formed by the articulations or hinges now acting as conveyor links of a scraper conveyor are discharged in the conveying direction and can be disposed of as waste.

In a further expedient embodiment of this subordinate inventive concept, the intermediate piece on the free end of each of its side bars a praral-IeI have to the top web of the adjacent longitudinal spar profile extending support flange, this also having a more than half of the width of the associated cover web of the adjacent longitudinal spar profile can have a width that overlaps. In this way, with a single profile, namely only the intermediate piece profile, not only the guide trough for the articulations or hinges of the plate or. Hinge band provided, but at the same time also an uninterruptible one Guiding the side edge areas of the same

- 11 -

not only a relatively large! area, but if the Width of the support flanges of the intermediate piece corresponds to the width of the cover flanges of the longitudinal spar profiles, even over maximum width, which even correspond to the maximum width of the frame of the belt conveyor device and in extreme cases even can go beyond this if this is ever necessary should.

In a further expedient development of the invention you can according to a subordinate concept of the invention, the longitudinal spar profiles each as U-profiles with different lengths Formed side bars and with its middle bar the cover bar and with its shorter side bar the connecting flange be arranged so that their longer side web each forms the outer web "or the side wall of the frame". Such a design has the advantage that, despite sufficient deformation rigidity of the frame, the inside of the The bottom is accessible, while its top is closed and the inside of the frame from incidence of, for example Waste, conveyed goods, fragments of the same or other foreign bodies or the like. Protects without any restrictions with regard to the structural design of the top of the frame would have to be accepted. This has especially been the case Not infrequently occurring applications have proven to be particularly advantageous in which "it applies to the belt conveyor easily and quickly additional units that are required during the conveying operation, such as metal detectors Od. The like. To set easily removable on the frame in the working position.

On the other hand, it can be especially for reasons of achievement adequate deformation stiffness of the frame with a further reduced profile wall thickness can be useful if in further development of this subordinate inventive concept the longitudinal spar profiles at the free end of their longer ones

- 12 -

Side bar one: * away from this in the direction of the Level of the conveyor normal central longitudinal plane of the belt conveyor have extending edge flange. This clearly results in an increase in the moment of resistance the longitudinal spar profile cross-sections and thus an improvement in the deformation rigidity with the possibility of corresponding Weight savings through cross-section reduction over the entire profile area. The hand flange one the space between the inside of the outer web of the longitudinal spar profile carrying it and the adjacent end a support roller, the J conveyor device should - be equipped with a number of the same, or a support crossbeam for the lower run of the conveyor cross or have a smaller width compared to this gap. In the former case, the Eandflansch can be used as Security element against unauthorized access to moving parts arranged inside the frame are used and this eliminates the need for corresponding other costly and installation-intensive measures, and in the latter case, with sufficient Deformation stiffness a securing effect that is sufficient for most cases of need can be achieved, as experience has shown For most belt conveyor designs, it is sufficient if the frame longitudinal beam areas near the outer web the interior of the frame are secured against unauthorized access.

To further improve the resistance of the frame according to the invention to deformations with the possibility of a corresponding reduction in cross-section and weight of the longitudinal spar profiles, according to a further inventive development, the longitudinal spar profiles can each have a stiffening flange at the free end of their edge flange that extends in the direction of the top web. This can era.trecken with inclination relative to the normal to the plane of the conveying means central longitudinal plane dör belt conveyor, while with upward with respect to this central longitudinal plane diverging or konvergieren4or.Neiguaag _<, wherein the angle of inclination

··· ** · «4 * 1 ti I

expedient "up to about 30 ° compared to this central longitudinal scene can be, while on the other hand the stiffening flange is also approximately parallel to this central longitudinal plane of the belt conveyor can extend. This! Further development of the invention makes it possible with advantage for the creation of Frame constructions of conventional design, existing longitudinal spar profiles also for the creation of frame designs to be able to use according to the invention and only provide a correspondingly adapted middle piece design for this purpose to have to. Here again it is of particular advantage that füa? a predetermined "or desired load-bearing capacity of the frame structure existing profile material for the longitudinal spar profiles can be used when using for the creation of conventional frame structures for Load capacities or deformation stiffnesses of comparable size would be completely unsuitable.

In a further expedient port formation, the stiffening flanges of both longitudinal spar profiles can also be one at the same time can be made useful for other tasks by arranging them in an aligned arrangement at least one row of in a regular manner Clearance holes arranged at a distance from one another and / or a row to the free edge of the respective stiffening flange Open slots for axles of pressure or guide rollers or rollers, shafts of additional units, Have connecting elements to connecting components or the like. So it is here in addition to the desired stiffening function, the respective longitudinal spar profile is also used, other complex connection or storage structures for the "required additional components of the belt conveyor device or additional units to make it superfluous by taking on these functions itself.

While so far frame designs according to the invention with frame interior that is basically open from the underside

'rem are envisaged, even if the peripheral areas see the Longitudinal strut profiles should have such a width that the entire frame width through the "two

^ the edge flanges to be extended of the two opposing • overlapping longitudinal spar profiles is overlapped, the Conception of the invention expedient for some applications

; to be carried further as far as according to another subordinate ideas of the invention with the stiffening

'Flange the longitudinal spar profiles in each case a side web of a bottom part designed as a U- or C-Erofile force- and / or is positively connected. The side bars of the bottom part and the associated stiffening flange of the adjacent longitudinal spar profile each at least one from a preferably center point or m center line symmetrical depression or recess in one component and one complementary thereto. The end-

j bulge in the other component, existing locking of both components exhibit. Since it will be desirable in most applications that the frame interior for making assembly or Adjustment work is accessible from below, in particular on the moving parts of the belt conveyor device it proved to be particularly preferable if, according to a Alternatively, at least one row of through or threaded holes in the stiffening flange of each longitudinal spar profile at a regular distance from one another and in each side web of the bottom part at least one row of through holes or from complementary to through holes of the associated stiffening flange of the adjacent longitudinal spar profile, seen threaded holes in the same grid arrangement provided iöt and adjacent longitudinal beam profile stiffening flanges • and bottom part Seitenatege means in complementary passage "or. Threaded holes in these one or more penetrating

Screw elements are screwed together.

A particularly expedient embodiment of this subordinate invention results when the base part is designed as a U-profile, in that it is positioned with its central web on the free strip edges of the stiffening flanges
f two longitudinal spar profiles and resting with its side webs, this is arranged to engage behind. In this way, namely can be calibrated without special additional measures to landlines <legungsverbindung of bottom portion and adjacent longitudinal beam profiles improved by the fact that this regardless of "whether \ them as kraftßchlüssige or as positive comparison | binding is carried out, loaded on compression and not on tension
can work. Of course also the ■ possibility within the scope of the invention is required, the bottom part with its two side \ webs between the outer sides of the stiffening flanges lying to arrange the 'two longitudinal rail profiles, in which case aller-; dings the Feetlegungsverbindungen, for example the one for this
related screw elements, are subjected to tensile stress and; therefore normally have to be dimensioned larger than i would be required for compressive or compressive loading. However, this last embodiment described i often brings the advantage} quicker and easier accessibility of the frame interior | * if necessary with it because after releasing derTestlegungsver- | In this version, the bottom part is simply josxth | falls out at the bottom.

An unexpected increase in the load-bearing capacity and resistance of the frame according to the invention
Both bending and torsion loads have occurred both in the case of designs with and those without a base part
result if, according to another subordinate inventive concept, the connections between the connecting flange of a
Longitudinal rail profile and associated side web of the intermediate

- 16 -

piece and / or between the stiffening flange of a longitudinal spar profile and associated side web of a possibly provided bottom part by slight divergence of the connecting flange and center piece side bar or stiffening flange and bottom part side bar in sight of their free edges to a pretension aimed at loosening these connections is applied. With a correct assessment of this preload and appropriate choice of the degree of divergence in each case the two components to be connected to one another can also surprisingly result in a further reduction in the. Profile cross-section dimensions with a corresponding weight saving which is advantageous in the manner described at the outset.

According to another subordinate inventive concept expediently the connection flange of each longitudinal spar profile is one in sighting on the normal to the level of the conveyor Have the central longitudinal plane of the belt conveyor device to angled stop area on which the intermediate piece is executed as a U-profile of the associated side web of the same and, if the intermediate piece is designed as a C-profile, of the associated side web in the direction of this central longitudinal plane of the belt conveyor extending edge web of the Intermediate piece rests. In this way, in spite of at least the same, if not the possibility of a further Reduction of the profile wall thickness with a corresponding reduction in weight offering the size of the profile cross-sections to be used extremely simply and economically further increase in the deformation stiffness of the invention Achieve frame construction. Pur the last described Case of using one designed as a C-profile Intermediate piece is to be pointed out that then expediently at least the stop areas of the connecting flanges of the longitudinal strut profiles each with the overlying edge web of the intermediate

-V-

piece, but preferably also the middle areas the connecting flanges of the side rail profiles each with the associated side web of the intermediate piece, should be connected, namely in a non-positive and / or positive manner

The longitudinal spar profiles can be useful in the context of the invention both as bent and / or die-cut pieces made of sheet metal or plastic material, for example also glass fiber reinforced Plastic (GRP \ with or without if necessary intermediate or downstream deep-drawing operation be or preferably by extruded or drawn profiles made of metal, but also made of a suitable plastic material for small conveyors in particular. In particular in the first case, in a further task-oriented port formation of the invention, those for the inventive frame used longitudinal spar profiles are also used for other tasks at the same time by, according to a other subordinate inventive concept at least one of the longitudinal spar profiles in the area of its longer side web at least one pot-like indentation into the interior of the profile into or bulge out of this with an approximately circular edge contour and preferably a center hole or with an approximately elliptical band contour and preferably at least two holes arranged on the longer axis of the same or a slot-like elongated hole extending on both sides of the same, preferably located symmetrically to this on know. In this way, increased deformation loads on the longitudinal spar profiles that are expected to be increased, for example, can be avoided without increasing the mass of the profile material and thus the weight of the same desired increases in Achieve deformation stiffness, but it gets through this At the same time, it is also possible to have bearings, couplings or other required or desired machine elements

- 18 -

in a more or less covert! »age and thus against Unauthorized or unintentional access is secured and accordingly occupational safety-friendly inside the profile area to accommodate the longitudinal frame arms.

The same is also possible according to an alternative to this subordinate basic concept, according to which at least one of the longitudinal hollow profiles in the region of its longer side web has at least one channel-like indentation running in the direction of its longitudinal axis j into the interior of the profile or bulging out of it with limited or over the having the entire length of the longitudinal spar profile extending above length. This embodiment offers the additional advantage that the arrangement of the to be housed in the deep area of the longitudinal spar profile machine element or other component od. Like. As part of the length of the channel-like mounting Chung or bulging of the same variable iöt _t which in storage of only a single type of profile or a small number of different profile designs the universality with regard to the variety of frame constructions for belt conveyor devices that can be created from this can advantageously benefit, whereby experience has shown that the rationalization possibilities, especially with regard to storage of erofilament material, acquisition costs for this and assembly effort, can be quite considerable.

In particular for reasons of good power flow management as well as special simplification of the profile production, it has become It has proven to be particularly expedient if, in a further embodiment of this subordinate inventive concept described above, the indentation (s) or bulge (s) are inclined Transitional areas between a flat central area and the

· «· · I IUI

adjacent areas of the longer side web of the side rail profile has or have. Furthermore, the indentation or bulge can preferably be in the flat central area at least one row of through or threaded holes can be provided at regular intervals from one another.

If necessary, according to a further subordinate concept of the invention, the longitudinal spar profiles in the area of their top web and / or their outer web forming the side surface of the frame and / or their lower edge flange can have at least one bead-like indentation or bulge, preferably symmetrical in the center or in the center line, in arrangement i along the longitudinal axis of the Have longitudinal spar profile. I choose the form and arrangement is in this case the expert corresponds I talking to, but requires no mistaking choose for the particular application loads to be expected that such stiffening beads is still some further operational functions of the belt conveyor can mitübernehmen according to the invention as For example, if the cover flanges of the longitudinal haQmprofile are equipped with linear bulges extending in the longitudinal direction of the same, which can then simultaneously serve as the run of the upper run of the conveying means leading edge boundaries for this.

Furthermore, it has proven to be particularly useful for certain applications, because extremely thin-walled material enables the intermediate piece, if, according to another subordinate inventive concept, this is supported in its central area by at least one cross member, preferably a plurality of cross members arranged at a distance from one another in the longitudinal direction of the frame η is. I.

In the majority of applications, an embodiment i - 20 -

of the frame according to the invention be sufficient "at which the longitudinal spar profiles are formed in one piece over practically the entire frame length, there can be in particular due to the requirements of the area of application a belt conveyor device containing such a frame according to the invention, however, also embodiments of Recommend invention in which the longitudinal spar profiles are formed in several parts over the frame length. Has it has proven to be particularly useful if the intermediate piece is made in one piece over practically the entire length of the frame is designed and thereby as a connecting element for adjacent sections of the multi-part longitudinal spar profiles serves or, alternatively, is also designed in several parts and parts of the same each have a joint Adjacent sections of the multi-part longitudinal spar profiles are arranged as a connecting element overlapping.

In the following, the invention will be made more preferred by way of some Exemplary embodiments that are shown schematically in the drawings are described in more detail purely by way of example. Show:

In Fig. 2 it is indicated on the left-hand side that the edge flange can have a relatively short length, which is selected depending on the required deformation resistance properties of the longitudinal rail profile and preferably also so that it at least covers the space between the inner surface of the longer side web 28 of the longitudinal rail profile 4 and the adjacent end face of an approximately intended pressing and / or guide roller 43 is covered protectively while illustrated on the right side of Fig. 2 that the edge flange 24 may also have a greater length _$ which may go as far as the rest of even that the entire length of such a pressure or guide roller is covered to protect against unauthorized access. And finally, it is also indicated in Fig. 2 that instead of a U-shaped center piece 19, as shown in FIG Use of existing material supplies in stock is deemed appropriate.

The frame design according to FIG. 3 differs from that according to FIG. 2 in two respects. On the one hand, namely are, as shown, the connection flanges here with

5 designated longitudinal spar profiles with an inclination towards the to the level of the Förderd.ttels, not shown, for example of a conveyor belt, normal central longitudinal plane m des

Frame 2 executed, namely with this running towards or with respect to the corresponding connecting flange 18 of the opposite longitudinal spar profile converging inclination. The angle of inclination <x can expediently be up to about 30 °, although also steeper or shallower slopes are possible. As can be seen, the side webs 20 of the intermediate pieces 19 are complementary contoured. Such a design can be particularly useful with a view to simplifying the alignment of the intermediate pieces 19 with respect to the "adjacent longitudinal spar profiles 5 may be useful when assembling the frame 2. It is it can be seen that the screw elements 31 here have an oblique axis Have an arrangement which, moreover, can also have advantages in terms of assembly.

On the other hand, the edge flanges 24 of the longitudinal spar profiles 5 are bent or cranked upwards, i.e. into the inside of the frame, that a reinforcing flange 25 is produced which is conducive to improving the deformation rigidity of the entire frame structure and which, as shown, is a mirror image of the connecting flange 18 of the relevant longitudinal spar profile 5 can be formed so that this can be used for both right-hand and left-hand mounting. However, other designs of stiffening flanges 25 than that shown in FIG. 3 are also possible, both with regard to the crank angle oc and / or shape and / or length thereof.

The frame design according to FIG. 4- corresponds to that according to FIG. 3 with the proviso that here the connecting flanges 18 of the longitudinal spar profiles, denoted here by 6, from the central longitudinal plane m of the frame 2 or the belt conveyor device 1 away or towards the web 28 or with respect to the corresponding connecting flange 18 of the opposite Longitudinal rail profile 6 to their free edges

are executed diverging and that the respective stiffening flanges extending an edge flange 24 25 in the same way in the direction of the profile web 28 to run away. Here, too, the angle of inclination Ot with respect to the central longitudinal plane m is preferably up to 30 ° and for the same reasons as in the embodiment according to FIG. 3, edge flange 24 with stiffening flange 25 corresponding to the cover web I7 with connecting flange 18 of the respective longitudinal spar profile 6 be formed. The intermediate piece shown can also be seen here with regard to its side webs 20 to the shape of the associated connecting flange 18 of the adjacent longitudinal spar profile 6 adapted. As can be seen here, too, the arrangement of the form-fitting connection is provided B screw elements 3I oblique axis.

In the frame design reproduced in Fig. 5 it is shown that the longitudinal spar profiles designated here with 7 can also be designed asymmetrically in any suitable manner, this being the example * in a combination of an embodiment of the upper area of the longitudinal spar profile according to FIG. 1 with an area below according to FIG. 4 to achieve the longitudinal spar profile 7 according to FIG. Furthermore, FIG. 5 shows purely for example that an intermediate piece 19 designed as a U-profile can also be used in the reverse arrangement than in FIG is fixed positively for example by means of screw elements 3I. In order to perform the intermediate piece 19 shown as a profile with an extremely small wall thickness, without affecting its frame forming function, as shown in Fig this intermediate piece can. Shown I9 be ^au f the underside of the cross-beam 33 supported by it to an intermediate feeding piece 34 , the one on the crossbar

is set, rests. This can also make a positive contribution to facilitating assembly because of the end face of the chuck that forms the support surface for the intermediate piece I9 5 ^ a predetermined altitude for the intermediate piece 19 can be defined, which results in lengthy adjustment and dismantling work during assembly superfluous. "|]

In this context it should be noted that an i,

Although such an arrangement of the intermediate piece 19 in no way excludes the use in connection with elastically flexible conveying means, such as conveyor belts or conveyor belts, it is particularly suitable for use in connection with plate or hinge belts as a conveying means, namely by the according to \

The profile interior of the intermediate piece 19, which is open at the top, is closed at the bottom and therefore undesirable diarrhea Particle-preventing runway for the articulations or hinges of such a conveyor is offered, the channel formed in this way also being advantageous as a conveyor trough for the discharge of foreign material that has got into them, such as shards or fragments from on the conveyor transported piece goods, can serve.

The two frame designs shown in FIG. 6 are also designed in particular for conveying means in the form of plate or hinge belts, but are not limited to this type of use. In the embodiment shown on the right in FIG. 6 of a longitudinal spar profile designated here with 9, a profile which essentially corresponds to the longitudinal spar profile 4 according to FIG. 2 is related, but which is modified to the extent that its cover web I7 is in the area! its outer sand a sieve-like stiffening bulge 35 and the hand flange 24 below a ■■ ;!

for profile stiffening as well as to avoid a sharp band edge on itself, has folded edge area 25. The design of the intermediate piece 19 could be the same as "in Pig. 5- but a different design is shown," in which the side web 20 of the intermediate piece 19 has an outwardly bent support flange 21 with which it sits on the top web 17 of the adjacent longitudinal spar 9 rests and ^>; supported there, with the same advantages in terms of facilitating assembly by avoiding complex alignment and adjustment work being achieved as with support by the crossbars 33, for example according to FIG. 5 *

In the embodiment shown on the left in Fig. 6, a different support support of the otherwise otherwise in the same way as in the embodiment according to FIG Here with 8 designated longitudinal spar profiles a to a stop area 22 angled or cranked side web 20 have. As shown, the intermediate piece 19 can with its support flange 21 on the cover web I7 of the adjacent longitudinal spar profile 8 are supported opposite this, in which case the support flange 22 can lie hollow andJonly the function of further improving the inherent rigidity of the frame construction and the connection between the intermediate piece 19 and the associated side web 18 of the adjacent longitudinal spar profile 8 takes place positively via approximately central web-parallel screw elements 31. Or it can be the stop areas 22 of the side bars 18 of the longitudinal spar profiles 8 also serve as support supports for the intermediate piece 19 by having its side webs 20 in terms of height are contoured so that when its median web area rests on the stop areas 22 of the longitudinal spar profiles 8, with respect to the Tragflaneche 21 of the intermediate piece I9 dor cover webs I7 of the associated longitudinal strut profiles 8 are hollow

In addition, the longitudinal spar profile 8 according to FIG. 6 still has the A special feature is that its lower edge flange 24 is only a very narrow and also approximately parallel to the central longitudinal plane having stiffening flange protruding into the interior of the frame.

The frame design according to FIG. 7 basically corresponds to that according to FIG. 6 on the left by namely the one designated here with 10 " Longitudinal rail profiles have practically the same cross-sectional training as the longitudinal rail profiles 8 according to Fig. 6 on the left, but with the exception that the lower edge flanges 24 of the longitudinal spar profiles 10 are kept much shorter than those of the longitudinal spar profiles 8 in order to allow them to intervene at the edge lengthening stiffening flanges 25 bent upwards or into the interior of the frame or cranked in the Space between the webs 28 of the two opposite one another
