Abstract:
When testing the cigarettes (10, 11) of cigarette groups (16, 17) in pockets (13, 14) of a conveyor, particularly a cigarette turret (12), difficulties relating to adequate spacing of the testing members (29 . . . 32) from one another arise when the cigarettes (10, 11) have an especially small diameter. In order to make undisturbed testing by means of moving the testing members (29 . . . 32) near to the end faces of the cigarettes (10, 11) nevertheless possible, these are tested successively in several, especially two steps, whereby during these testing cycles cigarettes, spaced a somewhat greater distance apart from one another in each case, are acted upon by the testing members (29 . . . 32). Particularly within cigarette rows (18 . . . 21) only every other cigarette is tested in each case.
Abstract:
Packaging is effected in a machine where correct filter-tipping and filling of the ends of the single cigarettes occupying the channels of a feed chute is monitored by a plurality of plungers, one to each channel, that are reciprocated axially toward and away from the ends of respective single cigarettes during the course of the work cycle. Each plunger carries a radial appendage, offered to a transducer by which a control signal will be produced in the event that the appendage assumes a given position on arrival of the plunger in contact with the end of the cigarette lying in its path.
Abstract:
In the packaging of cigarettes and similar articles, it is necessary to test for proper formation, in particular for a sufficient tobacco content. This test is preferably carried out in the region of shafts 12 or shaft groups 15, 16 of a cigarette magazine 11. A test block 38 with test plungers 39 takes effect at one end of the cigarette (tobacco side). On the opposite side, grab members for each tested cigarette are provided, in particular needles 41 the points 42 of which penetrate into the cigarettes or into a filter 43 of the latter. The defective cigarettes are drawn out of the group by retracting the needles.
Abstract:
A quality control device for cigarettes moving through a hopper (1) to a cigarette-packing machine. The hopper has a lower section with a plurality of cigarette-guiding down channels (2) set side by side, with each channel guiding an individual pile of cigarettes (S) downward toward an underlying chamber where a cigarette batch consisting of at least one layer of cigarettes set side by side will be formed and then transferred to the cigarette-packing machine. Near each of the cigarette-guiding channels (2), a cigarette-inspection sensor is provided at one or both ends of the cigarettes to control a cigarette ejection mechanism for discarding any defective cigarette found. In each one of the cigarette-guiding channels (2) there is provided a rotary cigarette-transfer device (3) that separates the respective cigarette-guiding channel (2) into an upper section (12) and a lower section (22). The cigarette-inspection sensors are associated with at least one cigarette position in the upper sections (12) of the channels. Every rotary cigarette-transfer device is so constructed, and so operated by the respective cigarette inspection sensor or sensors, that it transfers every regular cigarette (S) from the upper section (12) to the lower section (22) of a cigarette-guiding channel (2), whereas it moves any defective cigarette (S1) into an intermediate position where the cigarette-ejection mechanism is provided.
Abstract:
A cigarette packing machine with a plurality of passageways leading from a hopper, includes an ends testing device (16, 16a) for individual cigarettes, so that faulty cigarettes can be rejected from the hopper before the cigarettes are ejected in groups at the bottom of the passageways (2).Leading from the hopper are two channels (6, 8) feeding each of the passageways. In one embodiment of the invention cigarettes are held up for ends testing in alternate channels by suction ports (14) formed in inclined surfaces leading to each passageway. In a second embodiment a set of horizontal reciprocating wires (30, 32) acts as an escapement mechanism.
Abstract:
An arrangement for checking blocks of cigarettes comprises an electron camera tube for forming an image of ends of cigarettes of the block, and electric means responsive to illumination of elements of said image for creating a control effect under the control of said element illumination.

Abstract:
A method and a device for the optical testing of objects during the production and/or packaging of cigarettes, in particular of cigarette packs and/or blanks for cigarette packs and/or overprints and/or print substrates on or for cigarette packs, with the aid of a suitable testing device. For at least one feature characterizing the test object, in particular in a visual respect, a set of feature-value alternatives for the corresponding feature that are stored in a memory is displayed on a display means. By means of an input device, one of the displayed feature values of the set of feature-value alternatives is selected. The testing device is automatically set up or preset for the subsequent testing operations, in particular an evaluating device and/or an illuminating device and/or a suitable light detector of the testing device, the selection of the feature value influencing the setting up of the testing device.
