Abstract:
An apparatus for checking packs (10) for a correct configuration of their outer appearance, wherein the packs are transported in a downstream direction by a checking conveyor (15) in a region of a checking section (14) at a spacing from one another, wherein, positioned in the region of the checking section (14) are optoelectronic checking means (32, 33) for registering the outer appearance of a pack (10), and, wherein in the case of a defective pack (10), an ejector (34), located downstream of the checking means, is actuated for discharging the defective pack (10), said apparatus comprising:an activating sensor (39) in the region of the checking section (14) and located upstream of the checking means (32, 33), wherein the activating sensor (39) is activated by a pack (10) moved past the sensor and directly switches on the checking means (32, 33);located upstream of the checking conveyor (15), a feed conveyor (12) having a conveying speed and having conveying strands (19, 20) lying respectively on top and bottom side surfaces (23, 24) of the packs (10), wherein the packs (10) are transported by the feed conveyor (12) into an initial region of the checking conveyor (15) and are transferred thereto and a transfer conveyor, arranged in the region of transfer from the feed conveyor (12) to the checking conveyor (15), for gripping each pack (10) on a rear side (22) thereof for a precisely positioned introduction of the packs (10) into the checking conveyor (15),wherein the transfer conveyor comprises vaned wheels (62, 63) which run synchronously with the feed conveyor (12), gripping each pack (10) with a vane (66, 67) simultaneously from above and from below.
