Abstract

A measuring device serves for acquiring measurement values for measuring a tension in a conveying system. The measuring device is designed to guide a conveying member from a first section of the measuring device to a second section of the measuring device, to effect a deflection of the conveying member with regard to a straight-lined connection between the first and the second section and to detect measurement values corresponding to a reaction force according to this deflection. The measuring device includes surfaces for guiding rollers of the conveying member. One of these surfaces is a deflecting surface for deflecting the conveying member. The deflecting surface is formed on a deflecting element of a measuring element, and the reaction force is a force which acts upon the measuring element.

First claim

The invention claimed is:

1. A measuring device for acquiring measurement values for measuring a tension in a conveying system,
wherein the measuring device is designed to
guide a conveying member with rollers from a first section of the measuring device to a second section of the measuring device,
to effect a deflection of the conveying member with regard to a straight-lined connection between the first and the second section and
to detect measurement values corresponding to a reaction force according to this deflection,
wherein the measuring device comprises a guide channel with surfaces for guiding the rollers of the conveying member in at least one of a horizontal direction or a vertical direction, and wherein one of these surfaces is a deflecting surface for deflecting the conveying member, and the deflecting surface is formed on a deflecting element of a measuring element and the reaction force is a force that acts upon the measuring element.

2. The measuring device according to claim 1 , wherein the measuring device is designed for the positive guidance of the conveying member.

3. The measuring device according to claim 1 , wherein the measuring device comprises one or more measuring transducers for determining the measurement values, and the one or more measuring transducers are arranged for the contact-free measurement of a position of the measuring element with respect to a reference element.

4. A conveying unit, comprising a conveying track and a conveying member with rollers that is guided therein and further comprising at least one measuring device according to claim 1 for measuring a tension in the conveying member.

5. The conveying unit according to claim 4 , wherein the conveying member comprises conveying links that are concatenated to one another, and a conveying link comprises rollers for the support and for the guidance of the conveying links in the conveying track.

6. The conveying unit according to claim 5 , wherein rollers which roll on the deflecting element of the measuring element are guide rollers that effect a lateral guidance of the conveying links in a conveying track.

7. The conveying unit according to claim 5 , wherein the rollers that roll on the deflecting element of the measuring element are run rollers that effect a supporting guidance of the conveying links in a conveying track.

8. The conveying unit according to claim 4 , wherein the measuring device is designed such that at least two conveying links bear with their rollers on the measuring element at every point in time on operation of the measuring device.

9. The conveying unit according to claim 4 , wherein the conveying links in each case are elements of a plate conveyor or of a gripper conveyor or of a tray conveyor or of a modular belt conveyor or of a pocket conveyor or of a suspended conveyor.

10. A conveying facility comprising at least one conveying unit with a conveying member, with at least one measuring device according to claim 1 , for measuring a tension in the conveying member, with at least one drive and with a controller that is designed to closed-loop control the at least one drive in accordance with measurement values of the at least one measuring device.
