[0029] figure 1 A schematic perspective view of a cigarette stick machine of the applicant's model "PROTOS" is shown in the figure, and the main components of the machine are drawn on the figure. A brief description of the structure and function of the cigarette stick machine is given below.

[0030]A pre-dispenser 2 is supplied with tobacco in portions by a gate device 1. A take-out roller 3 of the pre-dispenser 2 is controlled to supplement a storage container 4 with tobacco, a vertical conveyor 5 takes tobacco from the storage container, and the vertical conveyor supplies tobacco to a storage shaft 6 in a controlled manner. A nailed roller 7 takes out a uniform stream of tobacco from the storage shaft 6. The tobacco stream is shaken off from the nails of the nailed roller 7 by a discharging roller 8 and is thrown to a spreading that circulates at a constant speed. On cloth 9.

Abstract

In a device and a method for measuring the diameter of at least one rod-shaped article (28), in particular in the tobacco processing industry, the rod-shaped article (28) is irradiated with a preferably optical beam (54a, 54b). A detection device (66) generates a signal which represents the shadowing of the beam caused by the rod-shaped article (28), and the diameter of the rod-shaped article (28) is determined from this signal. The invention is characterized in that the beam (54b) is divided into a plurality of partial beams (601-608) before it is projected onto the rod-shaped article (28), which partial beams are directed to the rod-shaped article in different directions. (28); and generates a plurality of signals, one of which each represents the shading of a part of the beam caused by the rod-shaped article (28).

Description

Technical field [0001] The invention relates to a device for measuring the diameter of at least one rod-shaped product, especially in the tobacco processing industry, which is equipped with at least one preferably optical measuring system having a radiation source for producing a The beam is used to irradiate the rod-shaped product, and a detection device is also provided for generating a signal representing the shading of the beam caused by the rod-shaped product, wherein the rod-shaped product can be positioned in the optical path between the radiation source and the detection device, Or it can be guided through the optical path, and the diameter of the rod-shaped product can be obtained from the signal generated by the detection device. In addition, the present invention also relates to a method for measuring the diameter of at least one rod-shaped product, especially in the tobacco processing industry. The method has the following steps: in particular, an optical beam is used ...
