Embodiment Construction

[0029] In the following figures, identical or identical types of elements or components are identified with the same reference numerals, so that a corresponding new description is omitted.

[0030] figure 1 An embodiment of the device according to the invention is briefly shown. Products 4 of the tobacco processing industry, such as cigarette rods, are located in the controlled area 1 . The products 4 are moved through this control zone in a single-layer arrangement by means of the mechanism 8 . Control zone 1 is indicated by a dotted line in the form of a closed curve. The mechanism 7 is used to illuminate the control area 1 , in particular the surface 5 of the lighting product 4 . Two camera units 2 , 3 are aimed at the surface 5 , which are connected to a unit 9 for evaluating the pictures taken by these camera units 2 , 3 . The two cameras 2 , 3 are arranged offset and at an angle to one another, ie they record the surface 5 from different directions. Furthermore, par...

Abstract

The present invention relates to a device and a method for controlling the products in tobacco processing industry in an electromagnetic manner, especially in an optical manner. In that case, the device provided in the present invention comprises at least two camera mechanisms (2, 3) that are aligned towards a controlled area (1) from different direction, wherein, at least a camera mechanism (2, 3) is aligned towards at least a product (4). The method provided in the present invention is characterized in: the controlled area (1) is shot by the camera mechanisms (2, 3) from at least two different directions, wherein, at least an photograph is taken from at least a product (4); then, the photographs are analyzed to ascertain whether unevenness exists on the products (4). Furthermore, the present invention further relates to a machine for tobacco processing industry with the device provided in the present invention.

Description

technical field [0001] The invention relates to a device and a method for the electromagnetic, in particular optical, control of products of the tobacco processing industry in a controlled area. [0002] Furthermore, the invention relates to a machine of the tobacco processing industry comprising such a device. Background technique [0003] Within the scope of the present invention, products of the tobacco processing industry are to be understood as articles, in particular rod-shaped and rod-shaped products, such as cigarettes, filter rods, multi-segment filter rods, rolling papers or wrappers, as well as markings on paper webs Glue on lettering or paper. [0004] In the optical control of such products of the tobacco processing industry it is usual to detect and analyze quality features of the product, such as the presence or absence of holes, stains, damage and others. [0005] Publication DE 34 20 470 A1 (corresponding to US Pat. No. 4,639,592) discloses a device for th...
