Abstract

The present invention relates to a pocket-type conveyor belt installation (2) having a plurality of carrying rollers (21) which are designed to support a pocket-type conveyor belt (1), preferably a lower conveyor belt edge (12) of a pocket-type conveyor belt (1), wherein the carrying rollers (21) are each connected in load-bearing fashion by means of at least one carrying roller holder (22) to a carrying frame (23) of the pocket-type conveyor belt installation (2). The pocket-type conveyor belt installation (2) is characterized in that at least one carrying roller holder (22), preferably a plurality of carrying roller holders (22), has at least one sensor element (4), which is arranged and designed to record at least a force and/or a change in force between the carrying roller (21) and the carrying frame (23).

First claim

The invention claimed is:

1. A pocket-type conveyor belt installation comprising:
a plurality of carrying rollers designed to support a pocket-type conveyor belt, wherein the pocket-type conveyer belt includes a lower conveyor belt edge;
a plurality of carrying roller holders designed to connect the plurality of carrying rollers to a carrying frame;
wherein a carrying roller holder of the plurality of carrying roller holders includes a sensor element designed to record at least a force and/or a change in force; and
wherein the sensor element is further designed to record a temperature at the location of the carrying roller holder.

2. The pocket-type conveyor belt installation as claimed in claim 1 , wherein the sensor element comprises at least one strain gauge.

3. The pocket-type conveyor belt installation as claimed in claim 1 , wherein the sensor element comprises at least one load cell.

4. The pocket-type conveyor belt installation as claimed in claim 1 , wherein
the carrying roller holder has a neck in the longitudinal direction (X) and the sensor element is arranged in the region of the neck.

5. The pocket-type conveyor belt installation as claimed in claim 1 , wherein
the sensor element is connected in one of a wired or wireless manner to a control unit in order to transmit signals.

6. The pocket-type conveyor belt installation as claimed in claim 5 , wherein
the control unit is designed to exercise open-loop and/or closed-loop control at least over a conveying speed in the conveying direction (A) of the pocket-type conveyor belt in accordance with the recorded force and/or change in force.

7. The pocket-type conveyor belt installation as claimed in claim 1 , wherein the sensor element is designed to be electrically supplied in a wired or wireless manner.

8. The pocket-type conveyor belt installation as claimed in claim 1 , wherein the carrying roller holder is designed to be replaceable with the sensor element.

9. The pocket-type belt conveyor belt installation of claim 1 , wherein the pocket-type conveyer belt further includes an upper conveyer belt edge and the lower conveyor belt edge is positioned below the upper conveyer belt edge.

10. The pocket-type belt conveyor belt installation of claim 9 , further comprising a plurality of tensioning rollers and designed to engage the upper conveyer belt edge.

11. The pocket-type conveyer belt installation of claim 10 , further comprising a control unit coupled to the sensor element, the control unit designed to determine mass flow, monitor filling level, adapt a conveying speed of the pocket-type conveyer belt based on the recorded force and recorded force information.

12. The pocket-type conveyer belt installation of claim 11 , wherein the control unit is designed to control bulk product by a product discharge chute switch based on the recorded force and the recorded force information.

13. The pocket-type conveyer belt installation of claim 12 , further comprising an evaluation unit configured to store the recorded force information.

14. The pocket-type conveyer belt installation of claim 13 , further comprising one or more additional sensor elements designed to record additional force information and wherein the stored recorded force information includes the recorded additional force information.

15. A pocket-type conveyor belt installation comprising:
a plurality of carrying rollers designed to support a pocket-type conveyor belt, wherein the pocket-type conveyer belt includes a lower conveyor belt edge;
a plurality of carrying roller holders designed to connect the plurality of carrying rollers to a carrying frame;
wherein a carrying roller holder of the plurality of carrying roller holders includes a sensor element designed to record at least a force and/or a change in force;
wherein the sensor element is connected in one of a wired or wireless manner to a control unit in order to transmit signals; and
wherein the control unit is designed to exercise open-loop and/or closed-loop control at least over a conveying speed in the conveying direction (A) of the pocket-type conveyor belt in accordance with the recorded force and/or change in force.

16. The pocket-type conveyor belt installation as claimed in claim 15 , wherein
the sensor element comprises at least one strain gauge.

17. The pocket-type conveyor belt installation as claimed in claim 15 , wherein the sensor element comprises at least one load cell.

18. The pocket-type conveyor belt installation as claimed in claim 15 , wherein
the carrying roller holder has a neck in the longitudinal direction (X) and the sensor element is arranged in the region of the neck.

19. The pocket-type belt conveyor belt installation of claim 15 , further comprising a plurality of tensioning rollers and designed to engage the upper conveyer belt edge.

20. The pocket-type conveyer belt installation of claim 15 , the control unit designed to determine mass flow, monitor filling level, adapt a conveying speed of the pocket-type conveyer belt based on the recorded force and recorded force information.
