Abstract

The invention relates to a corrugated board machine for producing corrugated board. The corrugated board machine comprises a detecting arrangement for detecting at least one web of corrugated board web, an order change cutting device arranged downstream of the detecting arrangement and an information processing device, which is in signal connection with the detecting arrangement. Furthermore, the corrugated board machine has a control device, which is in signal connection with the information processing device, with which the order change cutting device is in signal connection and as a function of a change identified by the information processing device of a first printing area printed on the web of corrugated board web to a second printing area printed onto the web of corrugated board web activates the order change cutting device to perform an order change on the corrugated board web.

Claims

1. A corrugated board machine for producing corrugated board, comprising

a) a detecting arrangement for detecting at least one printed web (15) of a corrugated board web (26),

b) an order change cutting device arranged downstream of the detecting arrangement,

c) an information processing device (49), which

i) is in signal connection with the detecting arrangement, and

d) a control device (53), which

i) is in signal connection with the information processing device (49),

ii) is in signal connection with the order change cutting device, and

iii) as a function of a change recognised by the information processing device (49) of a first printing area (61) printed onto the web (15) of the corrugated board web (26) to a second printing area (62) printed onto the web (15) of the corrugated board web (26) activates the order change cutting device for bringing about an order change on the corrugated board web (26).

2. A corrugated board machine according to claim 1, wherein the detecting arrangement is an optically operating detecting arrangement.

3. A corrugated board machine according to claim 1, wherein the information processing device (49) identifies the change of the first printing area (61) to the second printing area (62) by means of at least one of the group comprising image recognition and image comparison.

4. A corrugated board machine according to claim 1, wherein the information processing device (49) identifies the change from the first printing area (61) to the second printing area (62) by at least one change reference marking (64, 65) on the web (15) of the corrugated board web (26) or by an image comparison without change reference marking (64, 65).

5. A corrugated board machine according to claim 4, wherein the change reference marking (64, 65) is arranged in any position on the web (15).

6. A corrugated board machine according to claim 4, wherein the change reference marking (64, 65) is arranged laterally on the web (15).

7. A corrugated board machine according to claim 4, wherein the change reference marking (64, 65) is arranged centrally on the web (15).

8. A corrugated board machine according to claim 4, wherein the change reference marking (65) is formed by at least one geometric figure.

9. A corrugated board machine according to claim 1, wherein the detecting arrangement for detecting the web (15) comprises a detecting unit (46), which is arranged upstream of a gluing station (18) for gluing and connecting a corrugated board web (13) laminated on one side to at least one additional material web (15).

10. A corrugated board machine according to claim 1, wherein the detecting arrangement for detecting the web (15) comprises a detecting unit (47, 48), which is arranged downstream of a gluing station (18) for gluing and connecting a corrugated board web (13) laminated on one side to at least one additional material web (15).

11. A corrugated board machine according to claim 1, wherein the detecting arrangement for detecting the web (15) comprises a detecting unit (48) which is arranged downstream of a heating and pressing device (21).

12. A corrugated board machine according to claim 1, wherein the order change cutting device comprises at least one cross-cutting device (27, 36) for at least partly cross-cutting the corrugated board web (26) transversely to its conveying direction (38) to bring about the order change.

13. A corrugated board machine according to claim 12, wherein the control device (53) operates the at least one cross-cutting device (27, 36) such that the latter cuts into a change area between the printing areas (61, 62).

14. A corrugated board machine according to claim 1, wherein the order change cutting device comprises at least one longitudinal cutting device (30) adjustable perpendicular to a conveying direction (38) of the corrugated board web (26) for longitudinally cutting the corrugated board web (26) in its conveying direction (38) as a function of a respective order.

15. A corrugated board machine according to claim 1, wherein the detecting arrangement is also able to detect at least one remaining running marking (69) arranged on the web (15).

16. A corrugated board machine according to claim 15, wherein the information processing device (49) on the basis of the at least one detected remaining running marking (69) controls an unrolling device (16) for delivering the web (15) at a start of the next order.

17. A corrugated board machine according to claim 16, wherein the unrolling device (16) is a splicing device.
