Abstract

A method to operate a production plant having a plurality of work regions in which respective work stations are arranged to carry out at least on respective work step, and having at least one transport system that transports goods to be processed on at least one predetermined path between the work stations, involves selecting the arrangement of the work stations, the work step that is able to be carried out by the respective work station, and the at least one predetermined path according to at least one predetermined criterion that is related to a production requirement, and adapting these due to a change of the at least one criterion.

First claim

The invention claimed is:

1. A method of operating a production plant having a plurality of work regions in which no work stations are provided, a plurality of nonempty work regions in which respective work stations are arrange to carry out at least one respective work step, and at least one transport system that transports goods to be processed are transported on at least one predetermined path between the work stations, the method comprising:
selecting, according to at least one predetermined criterion related to a production requirement, an arrangement of the work stations, the work step that is to be carried out by the respective work station, and the at least one predetermined path;
initiating a change in the production requirement of the at least one predetermined criterion;
compensating for overloading of the production plant by providing at least one new work station in at least one of the empty work regions; and
adapting, according to the change of the at least one predetermined criterion, a current arrangement of the work stations, the work step that is to be carried out by the respective work station, or the at least one predetermined path,
wherein the same work steps are carried out in parallel at a number of the work stations, which are selected depending on a quantity of goods to be produced.

2. The method of claim 1 , wherein the work stations are formed as substantially identical modules.

3. The method of claim 1 , wherein each of the work stations is equipped with at least one mobile robot.

4. The method of claim 3 , wherein a program of the at least one robot is changed due to:
a re-equipping of a work station with the at least one robot;
a change of the work station by the at least one robot; or
a change of the work step to be carried out by the work station.

5. The method of claim 1 , wherein a plurality of work steps is carried out at each work station.

6. The method of claim 1 , wherein the same work steps are carried out for different product variants in parallel at a number of the work stations, which are selected depending on a quantity and number of product variants to be produced.

7. The method of claim 6 , wherein products of the work stations working in parallel are further transported by the transport system to an individual work station, where the produces are processed further.

8. The method of claim 1 , wherein products of the work stations working in parallel are further transported by the transport system to an individual work station, where the produces are processed further.

9. The method of claim 1 , wherein a predetermined number of unequipped work regions are provided to accommodate a predetermined number of new work stations.

10. The method of claim 2 , further comprising transporting goods between the work statins with a self-navigating industrial truck.

11. The method of claim 10 , wherein the self-navigating industrial truck is unmanned.
