Description of drawings
Below be limited to general plotting of the present invention, by means of embodiment the present invention exemplarily illustrated with reference to accompanying drawing.What all were described in detail in text can be clearly referring to accompanying drawing according to details of the present invention.Accompanying drawing is depicted as:
Fig. 1 summary is represented a kind ofly to be used for from the device of a flow of tobacco segregating foreign objects by of the present invention.
The specific embodiment
Tobacco 10 is placed on the swinging chute 17 on carrying direction 12.Swinging chute 17 has a bottom that is with holes 28, therefore breathes freely.Form a flow of tobacco 11 for 17 li at swinging chute, this flow of tobacco enters in the position of a suction band transport plane 14.This transport plane 14 includes a suction and is with 15, and this suction band rotates round two guiding rollers on the direction of arrow.Be provided with a suction box or a drawing mechanism 16 in addition, thereby make suction air enter into 16 li of drawing mechanisms from the below of suction band transport plane.Suction air is represented with Reference numeral 27.Suction is with 15 fabrics that are designed to breathe freely, so that corresponding windstream can be with by this suction.8 of tobacco 10 and foreign matters arrive the downside place of aspirating band by the suction air 27 with arrow (this arrow should be expressed a transmission direction 13) expression and also are sucked air 27 stickings there.
Since suction air therein tobacco be in the suction with on a position in design not too by force, and in the middle part, work fully, therefore other mainly moves in the intermediate cavity from the form of swinging chute 17 flow of tobacco part that lifted, pull-up to the suction band, that pick up or transportation with tobacco 10 or foreign matter 18, thereby on suction band transport plane 14 or below this transport plane 14, formed a kind of a single state of flow of tobacco basically.In the steering position, the drawing mechanism 16 of the flow of tobacco of transportation just no longer works on transporting direction 20, thereby these flow of tobacco continue to move in the position of a foreign matter identification mechanism to the bottom right with parabolic shape on the right.This foreign matter identification mechanism is made up of an optical detector 21 in the case, and this detector sends a light beam 22 or a light cone 23 and measures the light of its reflection towards flow of tobacco.Also be provided with a reference element 23 herein, it can be matched with or be matched with the color and the brightness of flow of tobacco.If discerned a kind of foreign matter, so can on the transporting direction just immediately following (about late 50-150mm) is separated to foreign matter 18 on the detaching direction 19 by means of a separating nozzle 24 (from this nozzle ejection pressurized air 25) in foreign matter identification mechanism back.
