Abstract
The ends of cigarettes (10) are verified in a cigarette magazine (12) by testing units (24, 25) coordinated with the ends of cigarettes (10) at a testing level (20). The testing units (24, 25) consist of mutually adjacent and removable testing elements (33) with transmitters (28, 29) and planar receivers (30, 31) at the sides of the cigarettes. The testing units (24, 25) are fitted so that they can move parallel to the axis of the cigarettes (10) relative to the cigarette magazine (12), so that the testing unit (25) can moved back in order to advance the cigarettes from the cigarette magazine (12).
Claims13
In a device for verifying correct formation of laterally directed opposite ends of cigarettes (10) in a region of upright test channels (17) in which respective individual cigarette rows (18) of superimposed cigarettes (10) are moved, from a top to a bottom of the test channels, wherein, in a region of a testing level (20), on at least one side of the test channels (17), a testing unit is arranged, and wherein the testing unit (24, 25) has sensors (28, 29, 30, 31), comprising transmitters (28, 29) and photosensitive receivers (30, 31), for transmitting and receiving a test light beam in a region of opposite end faces (27) of a test group (45) of the cigarettes and their adjacent side faces, the improvement wherein:
- a) the sensors (28, 29) of the testing unit (24, 25) are located adjacent the opposite end faces (27) of the cigarettes (10) of a test group (45);
- b) in a region of the testing unit (24, 25), each end face (27) of the cigarettes (10) of the test group (45) is associated with a separate one of said transmitters (28, 29);
- c) the photosensitive receivers (30, 31) respectively extend entirely over the end faces (27) of superimposed cigarettes (10), adjacent to the end faces (27);
- d) in the region of the testing unit (24, 25) the superimposed cigarettes (10) are associated with a common one of the receivers (30, 31) at both sides;
- e) the photosensitive receivers (30, 31) extend almost over the entire height of the superimposed cigarettes (10) of the test group (45);
- and
- f) the photosensitive receivers (30, 31) receive light emitted from each of the cigarettes (10) of a test group (45).
Device for verifying the ends of cigarettes (10) in a region of upright test channels (17) in which respective individual cigarette rows (18) of superimposed cigarettes (10) are moved from the top to the bottom with their laterally directed ends, in a cigarette magazine (12) of a packaging machine, wherein, in a region of a test plane (20), on one side of the test channels (17), a testing unit (46) is arranged with sensors (28 to 31), comprising transmitters (28, 29) and receivers (30, 31), for transmitting and receiving a test beam in a region of end faces of a test group (45) of the cigarettes (10), and their adjacent side faces, characterized in that a positioning unit (49) for flexibly and individually exerting pressure onto the cigarettes is arranged on a side of the testing channels (17) that is opposite the testing unit (46).
