Abstract
Method and apparatus (1a) for optical detection of the position of large-area printed products (10). The apparatus (1a) has conveyance means (2a) for movement of the printed products (10) along a conveyor path (4) past at least one contrasting light source (30), and at least one optical sensor (16). The conveyance means (2, 2a), the contrasting light source (30) and optical sensor (16) are arranged such that the printed products (10) can be conveyed between the contrasting light source (30) and the optical sensor (16).
Claims18
A method for optical detection of the position of flat printed print shop products (10, 10a, 10b), the method comprising:
- postpress processing the print shop products (10, 10a, 10b) on a circulating endless conveyor including a plurality of conveying sections (4);
- guiding the flat printed print shop products (10, 10a, 10b) by transparent conveying means (2, 2a) of one of the conveying sections (4) between at least one contrast light source (30) and at least one optical sensor (16);
- and
- irradiating a first side of the flat printed print shop products (10, 10a, 10b) by the contrast light source (30) to produce a silhouette (14, 14a, 14b, 14c, 14d, 14f), which is registered by the optical sensor (16).
An apparatus (1, 1 a, 1 b) for optical detection of the position of flat printed print shop products (10, 10a, 10b), the apparatus (1, 1 a, 1 b) comprising:
- a circulating endless conveyor including a plurality of conveying sections (4);
- and
- one of the conveying sections (4) including transparent conveying means (2, 2a) for moving the flat printed print shop products (10, 10a, 10b) along the one of the conveying sections (4) between at least one contrast light source (30) and at least one optical sensor (16), wherein the conveying means (2, 2a), contrast light source (30) and optical sensor (16) are arranged in such a way that a first side of the flat printed print shop products (10, 10a, 10b) is irradiated by the contrast light source (30) to produce a silhouette (14, 14a, 14b, 14c, 14d, 14f), which is registered by the optical sensor (16).
