Embodiment Construction

[0027] Figure 1 shows a schematic perspective view of the applicant's "PROTOS" type cigarette rod processing machine, showing the main components. The structure and function of the cigarette rod processing machine are briefly described below.

[0028] Portions of tobacco are supplied to the pre-distributor 2 through the gate 1 . The delivery roller 3 of the pre-distributor 2 additionally controls the storage container 4 with the tobacco, from which the steeply inclined conveying device 5 removes the tobacco, whose tobacco is fed in a controllable manner to a collection shaft (Stauschacht) 6 . A pin roll (Stiftwalze) 7 draws a uniform tobacco flow (Tabakstrom) from the gathering well 6, which is knocked out of the pins of the pin roll 7 by a deflection roll 8 and passed through a dispersing fabric (Streutuch) which moves around at a constant speed. )9 to swipe up.

[0029] The tobacco strands (Tabakvlies) thus formed on the dispersing fabric 9 are thrown into a screening devi...

Abstract

The invention relates to a measuring device, in particular to a device for measuring the diameter of at least one streak (28) in tobacco processing industry, comprising an optical measuring device (50). The invention is characterized in that: a radiation device (51) irradiating the streak (28) and a detection device (52) are arranged on the optical measuring device, the detection device (52) selects the shadow size (D ist) formed by the streak (28) optimally in short time detection, and generates and gives the signal of the diameter (D ist) of the streak (28), wherein, the streak (28) can limit or pass through a light path (56) transmitting between the radiation device (51) and the detection device (52); at least one group of illuminants (51a) preferred as light emitting diodes(LED) are arranged on the radiation device (51), and at least one group of photosensitive sensory devices preferred as the elements of charge coupled assembly, the photosensitive sensory devices are arranged relative to the illuminants (51a).

Description

technical field [0001] The invention relates to a device for measuring the diameter of at least one rod, especially for the tobacco processing industry, comprising at least one optical measuring device with an illumination device for illuminating the rod and a detection device, the detection device Preferably short-term detection of the size of the shadow formed by the strip which can be positioned in the light path propagating between the illuminating device and the detection device or through which a signal is generated giving the diameter of the strip light path. Background technique [0002] "Rod in the tobacco manufacturing industry" means cigarettes, filter rods, cigarillos, cigars and other rod-shaped smoking articles, with or without filters, ie regardless of the processing step in which the rod is placed. Furthermore, the term "rod" also refers to an endless rod, which is used in a defined processing step as a whole rod or, for example, as separated rod segments fo...
