The invention relates to a Rollgurtförderanlage, which comprises a belt body, at least one arranged at a first end of the Rollgurtförderanlage first guide roller for guiding the belt body, at least one at a first end of the

Rollgurtförderanlage opposite the second end of the Rollgurtförderanlage arranged second guide roller for guiding the belt body, and a plurality of between the at least one first guide roller and the at least one second guide roller arranged carrying rollers, wherein the at least one first guide roller and / or the at least one second guide roller driven by a drive means are. Rollgurtförderanlagen usually have drive means which exclusively the arranged at the ends of Rollgurtförderanlage guide rollers, also called head and / or tail drums drive, so that the drive power to guide the belt body, in particular a hose-shaped belt body, exclusively on the guide rollers on the belt body be transmitted. The support rollers arranged between the guide rollers usually have a smaller diameter than the guide rollers and merely serve to support the belt body. The idlers are not driven, but by the movement of the belt body along its guideway, the idlers rotate. In various situations, there may be an increase in resistance acting on the guide rollers, resulting in transferability to the belt body Drive power reduced, which can lead to a standstill of the entire Rollgurtförderanlage. The situations can be triggered, for example, if the

Changed belt body and a new good body is introduced into the Rollgurtförderanlage. Furthermore, these situations may also arise due to unfavorable weather conditions or due to special operating conditions.

The object of the present invention is therefore to provide a Rollgurtförderanlage of the type described above, in which the risk of reducing the force acting on the belt body drive power can be reduced.

The object is achieved according fiction, by a Rollgurtförderanlage with the features of claim 1. Advantageous embodiments and advantageous

Further developments are described in the subclaims. The solution of the invention is characterized in that at least one of the plurality of support rollers can be driven by means of at least one additional drive device.

The fact that now also the support rollers can be driven directly to exercise a rotational movement, a drive power in addition to the

Guide rollers are also transferred from the support rollers to the belt body. The support rollers are preferably driven separately from the guide rollers by the support rollers have one or more auxiliary drive means which are provided in addition to the drive rollers driving drive means. The auxiliary drive devices can drive the guide rollers

Drive devices and thus the main drive facilities are relieved. An oversizing of the guide rollers driving drive means can be avoided. In addition, a more accurate adjustment of the drive rollers driving the drive means can be made possible to a nominal operating condition. The support rollers are preferably not driven continuously or continuously by means of the auxiliary drive means, but the drive of the support rollers is dependent on demand. In normal operation, the support rollers are preferably not by means of Auxiliary drive device driven, but the support rollers rotate only with the movement of the belt body and are thereby offset solely by the movement of the belt body in a rotary motion. However, if the resistance acting on the guide rollers increases, thereby reducing the drive power transferable to the belt body via the guide rollers, the auxiliary drive means are put into operation and the idlers are driven by the auxiliary drive means so that the idlers can transmit drive power to the belt body. A reduction of transmitted to the belt body drive power and thus a

Reduction of the delivery rate of the belt body or the entire roller belt conveyor system can thereby be avoided even with an increase in the force acting on the guide rollers resistance. A standstill of the entire Rollgurtförderanlage can be prevented. By at least temporarily driving one or more

Carrying rollers by means of one or more auxiliary drive means can thus be made possible at least a short-term provision of additional drive power. In this way, due to the now possible, individual adaptation of the drive of the belt body to different situations, the flexibility of the roller conveyor and / or the conveying capacity of the roller conveyor can be increased. The

Rollgurtförderanlage can be designed such that already existing idlers are equipped with an auxiliary drive means and / or that in addition to the existing idlers carrying rollers with additional drive means in the

Rollgurtförderanlage be retrofitted or nachmontiert.

If two or more support rollers can be driven by means of an additional drive device, it is preferably provided that the at least two drivable support rollers are arranged in a frame. The frame preferably surrounds or surrounds the

Outer circumferential surface of the belt body, so that two or more arranged in a frame, drivable support rollers the belt body at different points or

Can drive locations along its outer peripheral surface, so that the drive power can be transmitted to the belt body at various points along the outer peripheral surface of the belt body. In this way, a drive of the belt body that is as uniform as possible over the circumference of the belt body can take place. The frame with the support rollers arranged in accordance therewith can also be arranged or mounted between existing carrying rollers or carrying roller stations.

In order to be able to adapt the roller belt conveyor to belt bodies with different diameters, the at least two drivable carrying rollers arranged in a frame can preferably be arranged to be displaceable radially relative to the outer peripheral surface of the belt body. The support rollers can be moved by the displaceable arrangement in the direction of the outer peripheral surface and from the outer peripheral surface of the belt body away. The support rollers can thus be moved or moved translationally in the plane perpendicular to the running direction or conveying direction of the belt body.

Preferably, at least a portion of the drivable support rollers in two

different, perpendicular to each other directions are moved in order to be easily and quickly adapted to the outer diameter of the belt body can.

Preferably, not only is a frame with drivable support rollers in the

Rollgurtförderanlage arranged, but preferably at least two frames are each arranged with at least two drivable support rollers between the at least one first guide roller and the at least one second guide roller. The frame with the drivable support rollers can be arranged at any position along the length of the belt body, wherein the frame can be arranged immediately adjacent to each other or between each existing support rollers or support roller stations and in particular retrofitted.

It can preferably be provided that at least two of the frames are arranged adjacent to each other, wherein the at least two support rollers of a first frame can be arranged offset to the at least two support rollers of the adjacent to the first frame second frame. As a result, by means of a reduced number of drivable carrying rollers over a larger longitudinal section of the belt body, an optimally adapted drive power can be transmitted to the belt body. The at least one auxiliary drive device is preferably a motor. For example, the engine may be an electric motor. By means of trained as a motor

Additional drive device can be an accurate, demand s oriented drive power generated for the support rollers. Due to the formation of the auxiliary drive device as

Motor can be done a quick connection and / or switching off the drive of the idlers.

In order to initiate permanently a maximum torque in the belt body, it is preferably provided that the at least one auxiliary drive means a

Has torque control.

Each driven support roller can be assigned an auxiliary drive device, so that each drivable support roller can be driven or driven separately.

If a drivable carrying roller has its own additional drive device assigned to it, then the additional drive device can be integrated in its associated carrying roller. For example, the auxiliary drive device can be installed in the housing of the support roller.

Alternatively, however, it is also possible for the additional drive device to be arranged outside the driven carrying roller. This can be provided if each support roller is associated with an auxiliary drive device or even if two or more idlers are assigned to an auxiliary drive device. It is preferably provided that the at least one auxiliary drive device is arranged at a distance from the at least one or more drivable carrying rollers.

To apply the drive power from the driven support roller on the

To improve belt body, it may further be provided that one or more of the drivable support rollers have a friction force increasing profiling and / or a friction force increasing coating. Slipping of the belt body on the drivable carrying roller can be prevented. By profiling and / or coating, the surface or the outer peripheral surface of the support roller can be roughened, so that an improved adhesion of the belt body can be achieved on the drivable support roller and thus the traction and to be transmitted to the belt body drive power can be improved.

The invention will be explained in more detail with reference to the accompanying drawings with reference to preferred embodiments. Show it:
