[0003] Technical field

[0004] The present invention relates to a conveyor belt device for conveying a conveyed good, a conveying system for conveying a conveyed good and a method for conveying a conveyed good.

[0005] Background of the invention

[0006] A wide variety of materials, such as bulk goods or individual items, can be conveyed on conveyor belts not only horizontally but also with a vertical component. Conveyor systems for steeply inclined conveyors are known, which, for example, have their drive located at the top of the conveying section. This drive thus transmits the entire tractive force, which consists of the self-weight of the tractive or load-bearing elements, the load weight, the resistance to movement, and the preload force. In these conveyor systems, the tractive force increases steadily with the conveying height and is therefore directly dependent on it. The throughput and conveying height of these systems are limited by their maximum tractive force, as the load-bearing elements used, such as belts, ropes, chains, etc., are restricted in their permissible load.

[0007] Furthermore, the conveyor belts can be coupled with a drive unit, although especially with vertical conveyors or conveyor belts with a vertical component there is a risk of decoupling between the conveyor belt and the drive unit.

[0008] IG: mk

[0009] It is an object of the present invention to provide a conveying system with which a secure coupling to a drive unit is maintained even when conveying a conveyed material vertically.

[0010] This task is provided by a conveyor belt device for conveying a conveyed good, a conveying system for conveying a conveyed good, and a method for conveying a conveyed good in accordance with the independent claims.

[0011] According to a first aspect of the present invention, a conveyor belt device for conveying a conveyed material in a conveying system is described. The conveyor belt device comprises a conveyor belt with a conveying surface on which the conveyed material can be placed, and a coupling profile configured such that a drive element of a conveying drive of the conveying system can be coupled to the coupling profile for driving the conveyor belt along a conveying direction. Furthermore, the conveyor belt device has two support rollers, wherein the conveyor belt has lateral edge sections opposite each other transversely to the conveying direction. At least one of the support rollers is arranged on the lateral edge sections, wherein the support rollers are configured such that they can be placed on a support area of ​​the conveying system and are movable along this support area in the conveying direction.

[0012] According to another aspect, a conveying system for transporting a conveyed material is described. The conveying system includes a conveyor belt device, as described above, for conveying the conveyed material. The conveying system also includes at least one drive unit for driving the conveyor belt (Our reference: H 1411 WO), wherein the drive unit comprises the drive element which is coupled to the coupling profile in such a way that the drive unit is coupled to the conveyor belt for transmitting a conveying force to drive the conveyor belt along a conveying direction. Furthermore, the conveying system includes a support area on which the support rollers can be placed and which can be moved along the support area in the conveying direction.

[0013] According to another aspect, a procedure for conveying a conveyed good is described using the conveying system shown above.

[0014] The conveying system according to the invention is used for conveying a material that is heavy and is to be conveyed, in particular, with a vertical directional component. The material can consist, for example, of rock fragments or other bulk materials with large dimensions and weights.

[0015] The conveyor belt system includes a conveyor track or conveyor belt. The conveyor belt can consist of, for example, a conveyor belt or belt conveyor, a conveyor chain, or a conveyor track comprising several conveyor links. A conveying profile, such as a profiled surface, a bucket conveyor-type conveying surface, or other support elements for carrying the conveyed material, can be arranged on the conveying surface of the conveyor belt.

[0016] The conveyor belt is movable along a conveying direction. The transverse direction of the conveyor belt, perpendicular to the conveying direction and along the width of the conveying path, is defined below.

[0017] The conveyor belt is designed as a closed loop. The conveyed material is transported along a conveyor path between a starting point and an end point, with the belt being connected at both the starting and end points. Our reference: H 1411 WO

[0018] The conveyor belt is deflected around pulleys. Alternatively, the conveyor belt can be wound up or coiled at one of its ends and then unwound.

[0019] Furthermore, the conveyor belt has a coupling profile opposite the conveying surface. This coupling profile is designed such that a drive element of the conveyor system's drive unit can be coupled to it to transmit a drive force to the conveyor belt. The coupling profile and the drive element can be designed to transmit the drive force via a frictional connection. For example, the coupling profile can have a rougher surface. Furthermore, the coupling profile and the drive element can be made of a material with a high coefficient of friction, such as rubber. Similarly, the coupling profile and the drive element can each have a roller between which the drive force is transmitted.As described in exemplary embodiments of the invention, the coupling profile can be designed to provide a positive-locking connection with a correspondingly designed drive element (for example, a drive belt of the type of a V-belt). The coupling profile and the corresponding drive profile of the drive element can thus, for example, have a corresponding tooth profile. Furthermore, the coupling profile or the drive profile can have other engagement structures, such as a rod element that runs transversely to a conveying direction of the conveyor track.

[0020] Furthermore, the conveyor belt device has a support roller on each lateral edge section spaced along the transverse direction. The support roller is designed to rest on a support area of ​​the conveyor system in order to transmit a weight force. The support area can, for example, have a bearing surface along which the support roller is movable. In another exemplary embodiment, described in more detail below, the support area can also have a support rail on which the support rollers rest and can move. Along the conveying direction, the support rollers can remain in constant contact with the support area and be moved along it.Alternatively, as described in the following exemplary embodiment, the support rollers can be decoupled section by section on the support area and, for example, in a certain area, for example in the drive area described below, from the support area.

[0021] A number of support rollers can be arranged along the lateral edge sections of the conveyor belt. In one exemplary embodiment, pairs of support rollers can be arranged directly opposite each other along the transverse direction (perpendicular to the conveying direction). Furthermore, pairs of support rollers can be arranged opposite each other on the lateral edge sections and offset from one another in the conveying direction.

[0022] By arranging support rollers on the conveyor belt and having these rollers roll along the support surface of the conveyor system, a low-vibration and robust guidance of the conveyor belt can be achieved. This reduces the risk of sporadic changes in the distance between the conveyor belt and the support surface, thus preventing decoupling between the coupling profile and the drive element. This ensures a more stable coupling of the conveyor belt to the drive system and provides reliable conveying of the goods.

[0023] According to another exemplary embodiment, the support rollers are attached to the lateral edge sections. The support roller can, for example, be attached to the lateral edge sections via corresponding axle sections. Our reference: H 1411 WO

[0024] The edges of the support rollers can be attached directly to the conveyor belt. Each support roller can have its own axle section for direct coupling to the conveyor belt. Alternatively, the support rollers can be attached to a connecting axle as described below.

[0025] According to a further exemplary embodiment, at least two support rollers are arranged at a distance from each other on a lateral edge section of the conveyor belt and in the conveying direction, wherein the distance between the two support rollers in the conveying direction is, in particular, more than 1 lm, in particular more than 2 m, in particular more than 3 m, or in particular more than 5 m. The distance and the number of support rollers depend on the belt and load weight. The maximum belt sag can be limited according to the minimum belt tension along the conveyor.

[0026] According to another exemplary embodiment, the support rollers are fastened by means of a bearing, in particular a plain bearing or a ball bearing. For example, a corresponding bearing bushing (plain bearing bushing or ball bearing bushing) can be incorporated into the conveyor belt, in which a corresponding axle section of a support roller is guided.

[0027] According to another exemplary embodiment, the conveyor belt has a coupling surface with a coupling profile located opposite the conveying surface, the coupling profile being arranged between the two support rollers spaced transversely to the conveying direction. Along the conveying direction, the support roller can thus transfer the weight of the conveyed material to the support area at the lateral edge sections of the conveyor belt device. Viewed transversely, in a central area of ​​the conveyor belt, i.e., between the edge sections, the coupling surface with the coupling profile is formed to provide a coupling with the drive element. Thus, for example, Our reference: H 1411 WO

[0028] The conveyor drive is positioned below the conveyor belt, i.e., protected below the coupling surface, to ensure the transmission of the drive force. During operation, the support rollers pass laterally over the centrally located conveyor drive, preventing them from obstructing each other.

[0029] According to another exemplary embodiment, the support rollers are arranged on a connecting axis that runs transversely to the conveying direction (i.e., in the transverse direction), the connecting axis being attached (directly or indirectly) to the conveyor belt. The connecting axis consists, for example, of such a hollow profile or of a solid, rod-shaped profile. The connecting axis can be designed to be sufficiently robust to absorb the corresponding weight of the conveyed material and transmit it to the support roller.

[0030] The connecting axle can, for example, be rotatably attached to the conveyor belt.

[0031] According to another exemplary embodiment, the connecting axle is rotatably attached to the conveyor belt by means of a bearing, in particular a plain bearing or a ball bearing. The support rollers can be fixed to the connecting axle accordingly. Alternatively, the connecting axle can be fixed to the conveyor belt itself.

[0032] According to another exemplary embodiment, the connecting shaft is fixed (rotatably) to the conveyor belt, and the support rollers are attached to the connecting shaft by means of a bearing. The support rollers can be rotatably mounted to the connecting shaft by means of a sliding bearing bushing or a ball bearing. Our reference: H 1411 WO

[0033] According to another exemplary embodiment, the connecting axis is guided through the conveyor belt transversely to the conveying direction. For example, a bore can be drilled transversely in the conveyor belt through which the connecting axis is guided. Alternatively, the connecting axis can be cast into the conveyor belt during its manufacture.

[0034] According to another exemplary embodiment, the connecting axis is attached to the conveyor surface. For example, corresponding eyelets or other types of mounting tabs can be attached to the conveyor surface, guiding the connecting axis. The conveyor belt is thus suspended from the connecting axis to transmit the corresponding weight force.

[0035] According to another exemplary embodiment, the connecting axle is attached to the coupling surface. The conveyor belt thus rests, for example, on the connecting axle to transmit the weight force. The connecting axle can also be coupled to the coupling surface by means of a receiving tab. Furthermore, the connecting axle can also be attached to the coupling surface by means of a material bond (adhesive bond).

[0036] According to another exemplary embodiment, the connecting axis between the conveyor belt and the coupling profile is fixed. For example, the coupling profile can be mechanically attached to the conveyor belt, such as by means of a screw connection. Alternatively, the coupling profile can be attached to the conveyor belt by means of a material bond, such as an adhesive bond. The coupling profile and the conveyor belt thus form a sandwich-like structure, with the connecting axis positioned and fixed between the coupling profile and the conveyor belt. Our reference: H 1411 WO

[0037] According to another exemplary embodiment, at least one of the support rollers is arranged between the coupling profile and the conveyor belt. In other words, the coupling profile can be arranged transversely to the conveying direction on a lateral outer region of the conveyor belt device. Accordingly, the conveying drive can be coupled to the coupling profile in this outer region, i.e., outside the support roller, to transmit a drive force to the conveyor belt device. For example, the coupling profile can consist of a rod element or a three-dimensional body, such as a polygon, which extends laterally outwards from a support roller. In this outer region, for example, the engagement teeth of the conveying drive or the drive profile can engage the coupling profile and move it in the conveying direction.

[0038] According to another exemplary embodiment, the coupling profile is fixed to the conveyor belt, particularly at the lateral edges of the conveyed material, preventing rotation. The coupling profile can be fixed directly to the conveyor belt, for example, by means of a screw connection, an adhesive bond, or a weld. Alternatively, the coupling profile can also be rotatably attached to the conveyor belt by means of a bearing, such as a ball bearing or a plain bearing.

[0039] According to another exemplary embodiment, the coupling profile is attached to a connecting axis in such a way that it is fixed against rotation relative to the conveyor belt. The coupling profile can also be fixed against rotation, for example by means of a welded connection, or rotatably attached to the connecting axis by means of a sliding bearing or a ball bearing. For example, the coupling profile can be arranged in a space between the conveyor belt and the support roller. Our reference: H 1411 WO

[0040] Accordingly, for example, the drive profile can be coupled with the coupling profile in this space.

[0041] According to another exemplary embodiment, the coupling profile forms a hollow profile through which the connecting axis can be guided, wherein the connecting axis is rotatably mounted in the coupling profile. The coupling profile can, for example, have a round or polygonal cross-section through which the connecting axis is guided. The connecting axis can, for example, be rotatably coupled to the coupling profile, for example by means of a ball bearing or a plain bearing. The coupling profile itself can be designed to be rotationally fixed and, for example, attached laterally to the conveyor belt.

[0042] According to another exemplary embodiment, the conveying surface has a lateral boundary wall extending in the conveying direction. The lateral boundary wall extends from the conveying surface and continues along the conveying direction. In particular, two lateral boundary walls are arranged opposite each other in the transverse direction and enclose the conveying surface so that the conveyor belt cannot leave the conveying surface laterally.

[0043] According to another exemplary embodiment of the conveyor system, the support area has at least one support rail extending in the conveying direction, wherein at least one of the support rollers can be coupled to the support rail. The support rail is designed such that a support roller can be coupled so as to be movable along the support rail. In particular, the support rail defines the direction of movement of the support roller along the conveying direction. The support rail prevents movement of the support roller in the transverse direction, so that precise guidance of the conveyor belt can be achieved by using the support rail. In particular, two opposing support rails are provided in the transverse direction, Our reference: H 1411 WO, which extend in the conveying direction. The conveyor belt can thus be guided precisely in the conveying direction on such a rail system without any undesirable lateral movements occurring in the transverse direction.

[0044] According to a further exemplary embodiment, the support area has at least one further support rail, which is spaced apart from the support rail transversely to the conveying direction. In particular, both support rails run parallel and are spaced apart at a constant distance. Support rollers, for example, can rest on each rail at a distance, and these rollers can be coupled, for example, to a connecting axle 201.

[0045] According to another exemplary embodiment, the drive element of the conveyor drive and the coupling profile are arranged between the support rail and the second support rail. The coupling profile and, correspondingly, the drive element can be arranged, in particular, below the conveyor belt for coupling purposes. Specifically, the coupling profile extends between the first support rail and the second support rail.

[0046] According to another exemplary embodiment, the support rail and the other support rail extend in different horizontal planes, at least in a predetermined rail section. For example, one support rail may be vertically higher than the other. Thus, the conveyor belt is also positioned relative to a horizontal plane, so that along the conveying direction, the conveyor belt runs diagonally, i.e., with a slope between the two support rails. In particular, the connecting axis of the two support rollers resting on the respective support rails has an angle to the horizontal plane. This connecting axis may, for example, assume an angle to the horizontal plane between 5° and 80°, in particular between 10° and 60°, and further, in particular, between 20° and 30° or 45°.

[0047] In another exemplary embodiment, the vertical height of the support rail and / or the additional support rail can be adjusted by means of a lifting mechanism. In particular, the support rail and / or the additional support rail can be mounted on adjustable vertical lifting rods (which, for example, can be adjusted in length electrically, pneumatically, or hydraulically), so that the vertical heights can be individually adjusted.

[0048] In particular, in an exemplary embodiment, a control unit can adjust the vertical height of the support rail and the further support rail, for example based on the weight of the conveyed goods, so that a predetermined tension and tightness of the conveyor belt can be set, especially in curved sections.

[0049] According to another exemplary embodiment, the rail section forms a curved section in which the support rail has an inner curve radius that is smaller than the outer curve radius of the additional support rail running on the outside. This adjusts the inclination of the connecting axis and, consequently, the inclination of the conveyed material, particularly in a short section of the conveyor belt system. This inclination ensures, for example, that the conveyed material remains on the conveyor belt surface due to centrifugal forces during cornering. It also ensures that the conveyed material remains taut during cornering.

[0050] According to another exemplary embodiment, the

[0051] The support rail with the smaller inner curve radius is positioned on a vertically higher horizontal plane than the other support rail with the larger outer curve radius. In other words, the inner support roller on the support rail is positioned higher than the outer support roller of the other support rail. This elevation allows the weight component of the conveyor belt and the conveyed material to counteract the pressure of the conveyed material on the support roller, and consequently on the support rail and the drive mechanism, thus improving belt tension during curve negotiation.

[0052] According to another exemplary embodiment, the conveying system has a drive area in which the drive element is coupled to the coupling profile. In a further exemplary embodiment, the drive area is arranged next to the support area in the conveying direction.

[0053] On the one hand, the conveying direction of the support area and the drive area can be provided in an overlapping manner, so that the support roller is coupled to the support area in this overlapping section and the drive elements are coupled to the coupling profile.

[0054] On the other hand, the support area can consist of several sections spaced apart in the conveying direction, with the drive area located between these sections. Accordingly, in an exemplary embodiment, the support rollers in the drive area are decoupled from the support area. Thus, the weight of the conveyor belt in the drive area is not transferred from the support rollers to the support area, but rather the weight is transferred from the conveyor belt to the drive element of the conveyor drive via the coupling profile. This results in a stronger force-transmitting coupling between the conveyor drive and the conveyor belt. Our reference: H 1411 WO

[0055] In one exemplary embodiment, the drive element is, for example, a deflection pulley around which the conveyor belt is guided. The drive area is thus located around the deflection pulley. Within this drive area, the support rollers are decoupled from the support area. The drive area can also be configured along a linear, straight guide section.

[0056] According to another exemplary embodiment, a pressure device is arranged in the drive area, configured to press the support rollers in the drive area against the drive element. The pressure device is designed such that the support rollers, although decoupled from the support area, are pressed towards it, thus generating an additional force beyond the force of gravity towards the support area and consequently towards the drive element. This prevents the risk of the coupling profile becoming decoupled from the drive element and increases the contact pressure of the coupling profile against the drive element, enabling more efficient and reliable transmission of the drive force.

[0057] According to another exemplary embodiment, the pressing device has at least one pressing roller. The pressing roller is arranged such that a pressing force is generated in the direction of the drive element when it passes a support roller.

[0058] According to another exemplary embodiment, the pressure device has a pressure rail which extends in the conveying direction and is designed such that the support rollers are coupled to the pressure rail in the drive area. As a support roller passes through the drive area, continuous guidance of the support roller along the pressure rail is thus provided. This allows, on the one hand, a continuous pressure force to be applied towards the drive element (Our reference: H 1411 WO). On the other hand, guidance can be provided along the conveying direction without risking lateral derailment of the conveyor belt in the drive area.

[0059] Furthermore, the clamping device, for example the clamping rollers and / or the clamping rail, can be pre-tensioned by a spring device. When the support roller makes contact with the clamping device, the clamping device is pushed away from the drive element, for example. The spring device is designed such that when the spring device is pushed away from the drive element, a spring force (restoring force) is generated, which acts in the direction of the drive element. This pushes the support rollers and, consequently, the coupling profile towards the drive element to ensure a secure coupling.

[0060] The pressure rail can, for example, form at least one overlapping area that extends into the support area. In other words, an end section of the pressure rail extending in its direction of travel can project into the support area. In this transition area, a support roller can be in contact with either the support area or the pressure rail in the drive area. In other words, in the overlapping area, the distance between the support area and the pressure rail is greater than the diameter of a support roller, ensuring that the support roller is only in contact with either the support area or the pressure rail. This reduces or prevents the support roller from lifting off or from being unguided in the overlapping area or in the transition area between the support area and the drive area.

[0061] According to another exemplary embodiment, the conveyor belt device and the length of the drive area are designed in such a way that at least two, on a lateral edge section of the Our reference: H 1411 WO

[0062] Support rollers are arranged along the conveyor belt and spaced apart in the conveying direction within the drive area. This ensures a homogeneous coupling between the coupling profile and the drive profile, particularly when the coupling occurs between two drive rollers located within the drive area. Therefore, when passing over the intermediate drive or the conveyor drive, at least two support rollers are in contact with the hold-down profile or pressure rail.

[0063] According to another exemplary embodiment, the distance between the rotating rollers in the conveying direction is in particular more than lm, in particular more than 2m, in particular more than 3m or in particular more than 4.5m.

[0064] According to another exemplary embodiment, the drive element of the conveyor drive has a drive profile, wherein the coupling profile of the coupling surface is coupled to the drive profile in such a way that the conveyor drive is positively coupled to the conveyor belt for the transmission of a conveying force.

[0065] The coupling profile and the corresponding drive profile can, for example, have a corresponding tooth profile. Furthermore, the coupling profile or the drive profile can have other engagement structures, such as a rod element that runs transversely to a conveying direction of the conveyor path.

[0066] The coupling profile extends, for example, in the conveying direction along the coupling surface of the conveyor belt. The first coupling profile can be detachably attached to the conveyor belt, for example, by means of a screw connection. Alternatively, the coupling profile can be glued or welded to the coupling surface of the conveyor belt. It is also possible for the conveyor belt and coupling profile to be formed as a single, integral, and monolithic unit (Our reference: H 1411 WO). The conveyor belt can be made, for example, of a robust and flexible plastic and / or rubber material.

[0067] The conveyor drive generates a motive force to power the conveyor. For force coupling, the coupling profile is positively coupled to the drive profile to ensure precise and robust power transmission to the drive belt. The motive force can be used to drive the conveyor belt, particularly when transporting goods from a lower starting point to a higher endpoint at a certain incline or gradient. Due to the positive coupling, the motive force can also be used as a braking force. The conveyor drive thus acts as a brake, counteracting the movement of the conveyor belt. For example, when transporting goods from a higher starting point to a lower endpoint, it is necessary to brake the conveyor belt to maintain or reduce its speed.A conveyor drive can be designed as an electric motor, which can also be operated in generator mode. Furthermore, the conveyor drive can, for example, include a magnetic brake or an eddy current brake.

[0068] Due to the positive coupling of the conveyor belt with the conveyor drive, a robust power transmission can be provided, making the conveyor system suitable for heavy conveyed goods.

[0069] The coupling profile can, for example, form a tooth profile. The drive element with the drive profile can, for example, consist of a conveyor belt as a conveyor chain, in which the tooth profile of the first coupling profile selectively engages. Our reference: H 1411 WO

[0070] The coupling profile and / or the drive profile can be designed as a toothed belt profile. Accordingly, for example, the coupling surface and / or the drive track described below can be designed as a belt or as a belt conveyor.

[0071] According to an exemplary embodiment, the drive element has a drive track, wherein at least a section of the drive track runs parallel to the coupling profile of the conveyor belt's coupling surface. The drive track has a drive profile designed such that the drive profile engages positively with the coupling profile of the conveyor belt along the drive area. The drive area is, for example, three to four times as long in the conveying direction as the width of the conveyor belt in the transverse direction. The drive area can also be longer.

[0072] When using the drive track according to the invention, the drive force is not transmitted at a single point, but along an elongated coupling area. This allows the conveying force to be transmitted gently, as no localized force peaks occur during transmission. This results in lower stress on the drive track and consequently a more robust conveying system.

[0073] The drive path can, for example, form a drive belt, a drive belt or a drive chain.

[0074] According to another exemplary embodiment, the drive track forms a closed loop guided around two rotating rollers spaced apart in the conveying direction. The axes of rotation of the rotating rollers extend transversely. At least one of the rotating rollers can be designed as a drive drum or drive roller. These provide the conveying force, for example as a driving force or braking force, and transmit it to the drive track. The drive track is arranged and designed such that at least one section of the drive track is coupled to the coupling profile. The conveying drive transmits a certain driving force via the drive track to transport the conveyed material.

[0075] According to another exemplary embodiment, a drive roller is arranged between the rotating rollers to transmit a drive force to the drive track. The drive roller can, for example, be positively coupled or already enclosed with the drive track.

[0076] According to another exemplary embodiment, one of the rotating rollers is driven (for example by means of an electric conveyor drive) to transmit a driving force to the drive track.

[0077] It should be noted that the embodiments described here represent only a limited selection of possible embodiments of the invention. It is possible to combine the features of individual embodiments in a suitable manner, so that a multitude of different embodiments are to be considered obviously disclosed to the person skilled in the art with regard to the embodiments explicitly described here. In particular, some embodiments of the invention are described by apparatus claims and other embodiments by method claims. However, it will be immediately clear to the person skilled in the art upon reading this application that, unless explicitly stated otherwise, in addition to a combination of features belonging to one type of subject matter, any combination of features belonging to different types of subject matter is also possible.

[0094] The conveyor belt device 120 has a conveyor track or conveyor belt 121. The conveyor belt 121 is, for example, a conveyor belt. A conveying profile, such as a profiled surface, a conveying surface 122 in the manner of a bucket conveyor, or other support elements for carrying the conveyed material, can be arranged on the conveying surface 122 of the conveyor belt 121. The conveyor belt 121 is movable along a conveying direction 101.

[0095] The conveyor belt 121 is designed as a closed loop. The conveyed material 150 is transported along a conveyor path between a starting point and an end point, with the conveyor belt 121 being deflected by pulleys at both the starting point and the end point. The starting point can be located higher or lower than the end point. Our reference: H 1411 WO

[0096] Furthermore, the conveyor belt 121 has a coupling surface 123 with a coupling profile 124 opposite the conveying surface 122. The coupling surface 123 is designed such that a drive element of a conveyor drive 130 of the conveyor system 100 can be coupled to the coupling profile 124 in order to transmit a drive force to the conveyor belt 121.

[0097] The coupling profile 124 is designed to provide a positive-locking connection with a correspondingly designed drive element (for example, a drive belt similar to a V-belt). The coupling profile 124 and the corresponding drive profile 131 of the drive element can thus, for example, have a corresponding tooth profile. Along the conveying direction 101, a plurality of spaced-apart conveying drives 130 with corresponding drive elements can be provided to transmit a drive force at several points on the conveyor belt 121. In the conveying direction 101, correspondingly successive support areas 102 and drive areas 104 are provided.

[0098] Furthermore, the conveyor belt device 120 has support rollers 125 at each lateral edge section spaced along the transverse direction. The support rollers 125 are designed to rest on a support area 102 of the conveyor system 100 and to transmit a corresponding weight force. The support area 102 can, for example, have a bearing surface along which the support rollers 125 are movable. The support area 102 has a support rail 103 on which the support rollers 125 rest and along which they can move. Along the conveying direction 101, the support rollers 125 can be decoupled from the support area 102 in sections and, for example, in a drive section 104. Our reference: H 1411 WO

[0099] As can be seen in Figs. 2 and 3, a pair of support rollers 125 can be arranged directly opposite each other along the transverse direction (perpendicular to the conveying direction 101). The coupling profile 124 is arranged between the two support rollers 125, which are spaced apart transversely to the conveying direction 101. Along the conveying direction 101, the support rollers 125 can thus transfer the weight of the conveyed material 150 to the support area 102 at the lateral edge sections of the conveyor belt device 120. Viewed in the transverse direction, in a central area of ​​the conveyor belt 121, i.e., between the edge sections, the coupling surface 123 with the coupling profile 124 is formed to provide a coupling with the drive element. Thus, for example, the conveyor drive 130 can be arranged protected under the conveyor belt 121, i.e., below the coupling surface 123, to provide transmission of the drive force. As shown in Fig.As shown in Figure 3, the support rollers 125 pass laterally over the centrally arranged conveyor drive 130 during operation, so that the support rollers 125 and the conveyor drive 130 do not block each other.

[0100] The support rollers 125 are arranged on a connecting axis 201, which runs transversely to the conveying direction 101 (i.e., in the transverse direction), the connecting axis 201 being attached (directly or indirectly) to the conveyor belt 121. The connecting axis 201 consists, for example, of a hollow profile or a solid, rod-shaped profile. The connecting axis 201 can be designed to be sufficiently robust to absorb the corresponding weight of the conveyed material 150 and transmit it to the support roller 125.

[0101] The connecting axis 201 can, for example, be rotatably attached to the conveyor belt

[0102] 121 can be attached. The connecting axle 201 can be secured by the conveyor belt.

[0103] 121 is guided through transversely to the conveying direction 101. Our reference: H 1411 WO

[0104] The support area 102 has two support rails 103 spaced apart in the transverse direction, which extend in the conveying direction 101, wherein at least one of the support rollers 125 can be coupled to the corresponding support rail 103. The support rails 103 are designed such that a support roller 125 can be coupled so as to move along the support rail 103. In particular, the support rail 103 defines the direction of movement of the support roller 125 along the conveying direction 101.

[0105] The conveyor belt 121 can therefore be guided exactly in the conveying direction 101 on such a rail system without any unwanted lateral movements in the transverse direction.

[0106] The conveyor system 100 further comprises the drive section 104, in which the conveyor drive 130 and, accordingly, the drive element are coupled with the coupling profile 124. Along the conveying direction 101, several support sections 102 and drive sections 104 are arranged alternately. As shown in Fig. 1, in the conveying direction 101, the support section 102 and the drive section 104 can be arranged to overlap, so that in this overlapping section the support rollers 125 on the support section 102 are coupled with the drive section 104 (in other words, a support roller 125 is coupled with the pressure rail 105 and the support rail 103) and the drive elements are coupled with the coupling profile 124.

[0107] In drive area 104, outside the overlapping section, the support rollers 125 are decoupled from the support area 102. Therefore, the weight of the conveyor belt 121 in drive area 104 is not transferred from the support rollers 125 to the support area 102, but rather the weight is transferred from the conveyor belt 121 via the coupling profile 124 to the drive element of the conveyor drive 130. Our reference: H 1411 WO

[0108] A pressure device is arranged in the drive area 104, which is configured to press the support rollers 125 in the drive area 104 against the drive element. The pressure device is designed such that the support rollers 125, although decoupled from the support area 102, are pressed in the direction of the support area 102, so that an additional force to the weight force can be generated in the direction of the support area 102 and accordingly in the direction of the drive element.

[0109] The pressure device has a pressure rail 105 which extends in the conveying direction 101 and is designed such that the support rollers are coupled to the pressure rail 105 in the drive area 104. As a support roller 125 passes through the drive area 104, continuous guidance of the support roller 125 along the pressure rail 105 is thus provided. This allows a continuous pressure force to be applied in the direction of the drive element. Furthermore, guidance along the conveying direction 101 is provided without risking lateral derailment of the conveyor belt in the drive area 104.

[0110] At each end of the pressure rail 105, it has a section bent away from the conveyor drive 130. This allows a support roller 125 to slide along this bent section upon entering the drive area 104 and be pressed by the pressure rail 105 towards the drive profile 131. The support rails 103 can also have a corresponding bent section at their beginning and end, where the conveyor belt 121 has been broken away, to improve the guidance of the drive rollers 125.

[0111] Furthermore, the clamping device, for example the clamping rail 105, can be pre-tensioned by a spring device 301 or pre-tensioning spring (see Fig. 3). Upon contact of the support roller 125 with the clamping rail, Our reference: H 1411 WO

[0112] The pressure rail 105 is pushed away from the drive element, for example. The spring device 301 is designed such that when the spring device 301 is pushed away from the drive element, a spring force (restoring force) is generated which acts towards the drive element. This pushes the support rollers 125 and, accordingly, the coupling profile 124 towards the drive element to ensure a secure coupling.

[0113] The pressure rail 103 has an overlap area that extends into the support area 102. An end section of the pressure rail 103, extending in the direction of its length, projects into the support area 102. In this transition area, for example, a support roller 125 can be in contact with the support area 102 on one side and / or with the pressure rail 103 in the drive area 104 on the other. In the overlap area, the distance between the support area 102 and the pressure rail 103 is greater than the diameter of a support roller 125.

[0114] The conveyor belt device 120 and the length of the drive area 104 are designed in such a way that at least two support rollers 125, arranged on a lateral edge section of the conveyor belt 121 and spaced apart in the conveying direction 101, are present in the drive area 104.

[0115] The drive element of the conveyor drive 130 has a drive profile 131, wherein the coupling profile 124 of the coupling surface 123 is coupled to the drive profile 131 such that the conveyor drive 130 is positively coupled to the conveyor belt 121 for the transmission of a conveying force. The coupling profile 124 and the corresponding drive profile 131 can, for example, have a corresponding tooth profile. Our reference: H 1411 WO

[0116] The coupling profile 124 extends in the conveying direction 101 along the coupling surface 123 of the conveyor belt 121 and is arranged between the support rollers 125.

[0117] The conveyor drive 130 is located in the drive area 104. The conveyor drive 130 serves to generate a drive force in order to drive the conveyor belt 121. For force coupling, the coupling profile 124 is positively coupled to the drive profile 131 to ensure precise and robust force transmission to the drive belt.

[0118] The drive element has a drive track 132, wherein at least one section of the drive track 132 runs parallel to the coupling profile 124 of the coupling surface 123 of the conveyor belt 121. The drive track 132 has the drive profile 131, which is designed such that the drive profile 131 engages positively with the coupling profile 124 of the conveyor belt 121 along the drive area 104. The drive area 104 is, for example, three to four times as long in the conveying direction 101 as the width of the conveyor belt 121 in the transverse direction. The drive track 132 can, for example, form a drive belt, a drive belt, or a drive chain.

[0119] The drive track 132 forms a closed loop guided around two rotating rollers 133 spaced apart in the conveying direction 101. The axes of rotation of the rotating rollers 133 extend transversely. At least one of the rotating rollers 133 can be designed as a drive drum or drive roller. These provide the conveying force, for example as a driving force or braking force, and transmit it to the drive track 132. The drive track 132 is arranged and designed such that at least one section of the drive track 132 is coupled to the coupling profile. The conveying drive 130 transmits a certain driving force via the drive track 132 to convey the conveyed material 150. Our reference: H 1411 WO

[0120] The conveying surface 122 is enclosed by a lateral boundary wall 126, which extends in the conveying direction 101. The lateral boundary wall 126 extends from the conveying surface 122 and further runs along the conveying direction 101. In particular, two lateral boundary walls 126 are arranged opposite each other in the transverse direction and delimit the conveying surface 122, so that the conveyor belt 121 cannot leave the conveying surface 122 laterally.

[0121] Fig. 4 shows a schematic representation of a conveying system 100 according to an exemplary embodiment, with which a conveyed material 150 is conveyed in a vertical direction. The conveying system 100 and the conveyor belt device 21 are designed according to the exemplary embodiments shown in Figs. 1 to 3. A drive section 104 is provided between two support areas 102. The support rollers 125 are guided along guide rails 103 in the support area 104. In the drive section 104, the drive rollers 125 are guided on pressure rails 105 and pressed in the direction of the conveying drive 130. In the drive section 104, the coupling profile 124 is coupled to a drive profile 131 of the conveying drive 130. The conveying drive 130 has a drive track 132 that is guided around a rotating roller 133 and around a driven rotating roller 403. A drive motor 404 is provided on the driven rotary roller 403.Support rollers for 102 are provided between the circulating roller 133 and the driven circulating roller 403, on which the drive track 132 rests. At the same time, support rollers are provided, particularly on the side of the hold-down roller 401 furthest from the conveyor belt 121, to guide the drive track 132 between the hold-down rollers 401 and the support rollers 402. Thus, coupling between the coupling profile 124 and the drive profile 131 is ensured even with a vertically rising or falling conveying direction 101. Our reference: H 1411 WO.

[0122] Fig. 5 shows a schematic cross-sectional view of a conveyor system 100 similar to that in Fig. 1, wherein the support rollers 125 are arranged between the coupling profile 124 and the conveyor belt 121. The coupling profile 124 is thus arranged transversely to the conveying direction 101 on a lateral outer region of the conveyor belt assembly 120. Accordingly, the conveyor drive 130 can be coupled to the coupling profile 124 in the outer region, i.e., outside the support roller 125, in order to transmit a drive force to the conveyor belt assembly 120. For example, the coupling profile 124 can consist of a rod element or a three-dimensional body, such as a polygon, which extends laterally outwards from a support roller 125. In this outer region, for example, the engagement teeth of the conveyor drive 130 or the drive profile 131 can engage the coupling profile 124 and move it in the conveying direction 101.

[0123] For example, an axle extension, or a stepped extension of a connecting axle 201, can be attached to the lateral edges of the conveyor belt 121, on which the support roller 125 is rotatably mounted. The connecting axle 201 projects through the support roller 125, so that the coupling profile 124 can be fixed to the outside of the connecting axle 101, for example, in a rotationally fixed manner. The drive profile 131 passes outside the support roller 125 in the conveying direction 101, thus engaging with the coupling profile 124. The coupling profile 124 is then driven by the drive profile 131 in the conveying direction 101.

[0124] Fig. 6 shows a schematic cross-sectional view of a conveyor system 100 similar to that in Fig. 1 or Fig. 5, wherein the coupling profile 124 is arranged between a support roller 125 and the conveyor belt 121. The coupling profile 124 is attached to a connecting axis 201 such that the coupling profile 124 is rotationally fixed relative to the conveyor belt 121. The coupling profile 124 is thus located in a space between the Our reference: H 1411 WO

[0125] The conveyor belt 121 and the support roller 125 are arranged. Accordingly, the drive profile 131 is coupled to the coupling profile 124 in this space.

[0126] The coupling profile 124 has a hollow profile through which the connecting axis 201 is guided, the connecting axis 201 being rotatably mounted in the coupling profile 124. The connecting axis 201 can, for example, be rotatably coupled to the coupling profile 124, for example by means of a ball bearing or a sliding bearing. The coupling profile 124 is, for example, fixed against rotation to the conveyor belt 121, particularly at the lateral edges of the conveyor belt 121.

[0127] Fig. 7 shows a cross-sectional view of the conveyor system 100 similar to that in Fig. 2, wherein support rails 103, 703 have different vertical heights. Fig. 8 schematically shows a curve of the conveyor system 100 from Fig. 7.

[0128] The support area 102 has at least one further support rail 703, which is spaced transversely to the conveying direction 101 from the support rail 103. In particular, both support rails 103, 703 run parallel and are spaced at a constant distance. For example, 125 support rollers can rest on each rail at a distance, which are coupled, for example, to a connecting axle 201.

[0129] The drive element of the conveyor drive 130 and the coupling profile 124 are arranged between the support rail 103 and the further support rail 703. The coupling profile 124 and, accordingly, the drive element are arranged specifically below the conveyor belt for coupling purposes.

[0130] The support rail 103 and the further support rail 702 are at least in a predetermined rail section in different horizontal orientations. Our reference: H 1411 WO

[0131] The conveyor belt 121 is arranged in planes. For example, one support rail 103 can be horizontally higher than the other support rail 703. Thus, the conveyor belt 121 is also positioned relative to a horizontal plane 701, 702, so that along the conveying direction 101, the conveyor belt 121 runs diagonally, i.e., with a slope between the two support rails 103, 703. In particular, the connecting axis 201 of the two support rollers 125, which rest on the corresponding support rails 103, 703, has an angle to the horizontal planes 701, 702. The connecting axis can, for example, assume an angle to the horizontal planes 701, 702 of between 30° and 45°.

[0132] As shown in Fig. 8, the rail section can represent a curved section 801 in which the support rails 103 have an inner curve radius RI that is smaller than an outer curve radius R2 of the outermost support rail 703. Thus, the inclination of the connecting axis 201 and, in particular, the inclination of the conveyed material 121 in the curved section of the conveyor belt device 120 is adjusted.

[0133] The support rail 103 with the smaller inner curve radius RI runs on a vertically higher horizontal plane 702 than the other support rail 703 with the larger outer curve radius R2. In other words, the inner support roller 125 on support rail 103 is positioned higher than the outer support roller 125 of the other support rail 703. This elevation allows the weight component G from the conveyor belt 121 and the conveyed material 150 to act against the tension force F and the contact force of the conveyed material 150 on the support roller 125 and, consequently, on the support rails 103 and 703, as well as on the drive device, thus improving the tension of the conveyor belt 121 during curve travel.
