Embodiment Construction
[0054] in figure 1 In a front view, a filter installation machine (Filteransetzmaschine) is partially shown, wherein the filter installation machine receives double-use length tobacco rods via a drum set T, the drum set for input from the schematic Draw the tobacco rods of the cigarette-forming machine (Zigarettenstrangmaschine) P. The cigarette forming machine is known to be named "PROTOS" of the applicant.
[0055] On its conveying path to an assembly drum 21, the double-use length tobacco rod 82 is cut and longitudinally expanded. On the assembly drum 21, the double-length filter plug 85 is transferred via another drum group M, and the filter plugs are respectively inserted between two longitudinally and axially spaced tobacco rods. As a result, a row of tobacco rod-filter plug-tobacco rod groups arranged in succession in the transverse and axial directions is formed on the assembly drum 21. The assembled product group is transferred from the assembling roller 21 to a convey...

The invention relates to an image shooting device (42-45) rod-shaped article (52-52''') for optical inspection in tobacco processing industry. The image shooting device includes a camera (50, 51), wherein the camera (50, 51) are arranged for shooting at least two images of at least one rod-shaped article (52-52''') or at least one image of at least two rod-shaped article (52-52'''). With respect to each image, at least one optical path (61-64) from the corresponding rod-shaped article (52-52''') to the camera (50, 51) and passing the at least one reflection optical device (55-55''', 72) and a method for optical inspection of rod-shaped articles from the tobacco processing industry is provided. The invention is characterized in that each optical path (61-64) has a path length, wherein the path length of at least one first optical path (61, 63) fits that of a second optical path (62, 64) through a path length fitting device (56, 56', 70, 70').
Description
Technical field [0001] The present invention relates to an image capturing device for optically testing rod-shaped products in the tobacco processing industry, comprising a camera, wherein the camera is configured to simultaneously capture at least two images of corresponding at least one rod-shaped product or corresponding Corresponding at least one image of at least two rod-shaped products, wherein for each image, an optical path from the corresponding rod-shaped product to the camera through at least one first reflective optical device is correspondingly set. The present invention also relates to a method for optically testing rod-shaped products in the tobacco processing industry, wherein at least two images of corresponding at least one rod-shaped product or corresponding at least two rod-shaped products are simultaneously captured by means of a camera, Wherein, for each image, the light is reflected from the at least one rod-shaped article through the first reflective opti...
