Method for a production plant, system and production plant

1 . A method for providing a conveying speed profile for a drive mechanism of a conveyor belt of a production plant, wherein the production plant comprises an IS machine for manufacturing glass containers and the conveyor belt for conveying the glass containers, wherein glass containers are placed on the conveyor belt and/or the conveyor belt conveys away glass containers, wherein position data of the glass containers on the conveyor belt are detected, wherein a belt elongation is determined on the basis of the position data, wherein the belt elongation relates to individual belt segments of the conveyor belt and wherein the conveying speed profile for the conveyor belt is provided on the basis of the belt elongation.

2 . The method according to claim 1 , wherein at least one portion of an individual glass container is placed and/or conveyed away for each belt segment or each two adjacent belt segments, in particular wherein two adjacent belt segments form a pitch in the range between 5 and 25 mm in a circumferential direction of the conveyor belt.

3 . The method according to claim 1 , wherein time intervals and/or local distances of conveyed glass container from one another are determined on the basis of the position data.

4 . The method according to claim 1 , wherein the conveying speed profile is provided on the basis of the intervals.

5 . The method according to claim 1 , wherein the conveying speed profile is provided to compensate for the belt elongation during the operation of the conveyor belt, in that the conveyor belt is operated faster in a section with an elongated belt segment than in a section with a belt segment, which is shorter than the elongated belt segment.

6 . The method according to claim 1 , wherein the conveying speed profile is sent to the drive mechanism or is retrieved from the drive mechanism.

7 . The method according to claim 1 , wherein the drive mechanism is operated on the basis of the conveying speed profile.

8 . A system for performing the method according to claim 1 , with a sensor device for detecting the position data and with a control device, which is configured to provide the conveying speed profile.

9 . The system according to claim 8 , wherein the sensor device comprises a light barrier and/or a camera and/or a distance sensor.

10 . The production plant comprising the IS machine for manufacturing glass containers, the conveyor belt for conveying the glass containers and the system configured for providing the conveying speed profile that compensates for belt elongation of the conveyor belt in some sections, wherein the system is configured according to claim 8 or the conveyor belt is configured to be operated on the basis of the conveying speed profile.
