Abstract

Examples include activating at least one alignment segment of a processing machine. The at least one alignment segment is arranged before at least one processing unit of the processing machine that is activated. The at least one alignment segment includes a plurality of transport sections following one another in the transport direction. At least two transport sections, following one another in the transport direction, each have a basic position and at least one adjustment position. The at least one adjustment position in each case is offset relative to the basic position in the transverse direction. At least one transport section of the transport sections is axially adjusted. At least one dedicated drive axially adjusts the at least one transport section of the transport sections, and the at least one dedicated drive is designed as a direct drive.

First claim

The invention claimed is:

1. A method for activating at least one alignment segment ( 750 ) of a processing machine ( 01 ), the at least one alignment segment ( 750 ) arranged before at least one processing unit ( 600 ; 900 ) of a processing machine ( 01 ) being activated; the at least one alignment segment ( 750 ) comprising a plurality of transport sections ( 706 ) following one another in the transport direction (T); at least two transport sections ( 706 ), following one another in the transport direction (T), of the transport sections ( 706 ) each having a basic position and at least one adjustment position, the at least one adjustment position in each case being offset relative to the basic position in the transverse direction (A); at least one transport section ( 706 ) of the transport sections ( 706 ) being axially adjusted; and at least one dedicated drive (ME) axially adjusting the at least one transport section ( 706 ) of the transport sections ( 706 ), characterized in that the at least one dedicated drive (ME) is designed as a direct drive.

2. The method according to claim 1 , characterized in that at least two transport sections ( 706 ) of the at least two transport sections ( 706 ), each having a basic position and at least one adjustment position, travel lengths of a path from the basic position thereof to the at least one adjustment position thereof, and vice versa, which differ relative to one another, that at least one transport section ( 706 ) of the at least two transport sections ( 706 ) travels a maximum length of the path between the basic position and the at least one adjustment position of all transport sections ( 706 ) carrying out an adjustment movement, that at least one transport section ( 706 ) of the at least two transport sections ( 706 ), which is arranged in the transport direction (T) before the at least one transport section ( 706 ) having a maximum length of the path between the basic position and the at least one adjustment position of all transport sections ( 706 ) carrying out an adjustment movement, travels a shorter length of the path between the basic position and the at least one adjustment position than the at least one transport section ( 706 ) having the maximum length of the path.

3. The method according to claim 1 , characterized in that an adjustment movement from the basic position toward the at least one adjustment position is carried out by the at least one transport section ( 706 ) of the at least two transport sections ( 706 ) until the at least one adjustment position is reached and/or until the substrate ( 02 ) to be aligned leaves the active region of the transport section ( 706 ).

4. The method according to claim 1 , characterized in that an axial offset of a substrate ( 02 ) to be transported is incrementally compensated for by the at least two transport sections ( 706 ), each having a basic position and at least one adjustment position.

5. The method according to claim 1 , characterized in that at least one group of transport sections ( 706 ) of the at least two transport sections ( 706 ) starts the adjustment movement from the basic position toward the at least one adjustment position together.

6. The method according to claim 1 , characterized in that a start of a return movement from the at least one adjustment position toward the basic position of at least two transport sections ( 706 ) of the at least two transport sections ( 706 ) takes place chronologically one after the other, and/or that at least two consecutive transport sections ( 706 ) of the transport sections ( 706 ) carry out a return movement from the at least one adjustment position toward the basic position simultaneously with one another at at least one point in time.

7. The method according to claim 1 , characterized in that the at least two transport sections ( 706 ) having a basic position and at least one adjustment position are each adjusted by at least one dedicated drive (ME) for the axial adjustment from the basic position into the adjustment position thereof, and/or vice versa, and/or that the at least two transport sections ( 706 ), arranged one behind the other in the transport direction (T), of the transport sections ( 706 ) of the alignment segment ( 750 ) are driven in the circumferential direction by at least one main drive (M).

8. The method according to claim 1 , characterized in that the axial adjustment of the at least one transport section ( 706 ) takes place in each case from the basic position thereof, that the at least one transport section ( 706 ) of the transport sections ( 706 ) is accelerated from the axial idle position thereof until it has an axial adjustment speed, and that the at least one transport section ( 706 ) is then moved at the axial adjustment speed until the at least one adjustment position has been reached.

9. The method according to claim 1 , characterized in that a substrate ( 02 ) is transported within the at least one alignment segment ( 750 ) in a plane and/or that the central axes of the transport sections ( 706 ) of the plurality of transport sections ( 706 ) following one another in the transport direction (T) are located in a plane and/or that a transport path of substrate ( 02 ) is located beneath the central axes of the transport sections ( 706 ) of the plurality of transport sections ( 706 ) following one another in the transport direction (T).

10. The method according to claim 1 , characterized in that the at least one alignment segment ( 750 ) arranged between two consecutive processing units ( 600 ; 900 ) is activated.

11. The method according to claim 1 , characterized in that at least one first group comprising at least two transport sections ( 706 ) of the plurality of transport sections ( 706 ) and at least one second group comprising at least two transport sections ( 706 ) of the plurality of transport sections ( 706 ) follow one another in the transport section (T), that the transport sections ( 706 ) of the at least one first group and the transport sections ( 706 ) of the at least one second group each have a basic position and at least one adjustment position, that the transport sections ( 706 ) of the at least one first group carry out an adjustment movement from the respective basic position thereof toward the at least one adjustment position simultaneously at at least one point in time, and that, simultaneously with the adjustment movement of the at least one first group, at least one transport section ( 706 ) of the transport sections ( 706 ) of the at least one second group carries out a return movement from the respective at least one adjustment movement toward the basic position.

12. The method according to claim 1 , characterized in that each of at least three alignment regions of the alignment segment ( 750 ) comprises at least two transport sections ( 706 ) following one another in the transport direction (T), that, in a first step, at least one first alignment region of the at least three alignment regions of the alignment segment ( 750 ) for aligning a skewed position is activated based on ascertained data, that, in a second step, at least one second alignment region of the at least three alignment regions of the alignment segment ( 750 ) for aligning an axial offset is activated based on ascertained data, that, in the second step, the at least one transport section ( 706 ) of the transport sections ( 706 ) of the at least one second alignment region is being axially adjusted, and that, in a third step, at least one third alignment region of the at least three alignment regions of the at least one alignment segment ( 750 ) for aligning an offset in the circumferential direction is activated based on a
