Description
Technical field
The utility model relates to the particularly device of the bar diameter of the tobacco industry of a kind of measurement, wherein comprises at least a commercially available laser measuring device for measuring, and this laser measuring device for measuring is named as light transmission type laser sensor usually.This laser measuring device for measuring has a generating laser and a receiver; The collimated laser beam of generating laser emission certain width; This bar is placed between the light path of generating laser and receiver; Because the covering effect of bar, receiver detect the shade size of this bar formation and produce the electric measurement signal of the diameter of this bar.For detecting the out-of-roundness of bar, this measurement mechanism is to rotate around the longitudinal axis that detects thing.
Background technology
[0002] " bar in the tobacco industry " is meant band or not filter-tipped cigarette, filter stick, cigarlet, cigar and other shaft-like tobacco product, and be promptly irrelevant with the residing procedure of processing of bar." bar " also refers to a kind of anury bar in addition, it in the procedure of processing of confirming as whole bar or the bar section of having separated that for example is used to process above-mentioned tobacco product.
Particularly when processing cigarette and filter tip, its diameter is the gross characteristic that adds the monitoring in man-hour.To this, vertically be that its y direction was carried a measurement mechanism continuously or discontinuously with this bar usually.The difficulty of accurately measuring diameter is that this bar normally " is not justified ", and promptly vertical with its longitudinal axis cross section and circle be some deviation more or less.
EP0909537A1 discloses a kind of measurement mechanism, and irradiation unit wherein produces a wide collimated light beam, and its turns to 90 degree to reflex on the checkout gear through a mirror.This bar is parallel with mirror and extend and location like this perpendicular to light path; Promptly make the part of light beam directly shine on this bar from irradiation unit; And another part of light beam is shining on this bar after the reflection on the mirror; The light beam that shines like this on the checkout gear produces two shadow regions side by side, and they have shown the diameter on two cross section axis that are perpendicular to one another.Though can produce in the restriction that receives operation does not need or undesirable when the longitudinal axis rotates, this known measurement mechanism also is fit to measure those bars, and is particularly suitable for measuring the anury bar thus.Yet it is not accurate enough only on two cross section axis, measuring diameter as a rule.
In addition; DE19523273A1 has described a kind of particularly method and apparatus of the diameter of cigarette of the tobacco industry bar of measuring; Wherein this bar is rotated through a static measurement mechanism when carrying; When light beam rotation stopped, the size of at least one light beam shade that respective detection is produced by bar also converted electric measurement signal into and is formed the signal of bar diameter by a plurality of such measuring-signals.Can improve its certainty of measurement through such well-known schemes, but this known scheme is not suitable for measuring the diameter of anury bar especially, because the anury bar can not be around its longitudinal axis rotation.
In addition, CN 100459893C has described a kind of particularly method and apparatus of the diameter of cigarette of the tobacco industry bar of measuring.This bar need not be suitable for measuring the diameter of anury bar around its longitudinal axis rotation.This measurement mechanism also uses illuminator and sensor, and is that electric measurement signal detects diameter according to light beam through the shade size conversion that measurement object forms.Its characteristics are that illuminator and sensor form a local at least rounded arc.Can detect the diameter of anury bar with degree of precision through such well-known schemes; But this well-known schemes need be used circular-arc sensor; And in order to improve accuracy of detection, needing as much as possiblely to sensor group, this can cause size sensor big and cost is higher.
Summary of the invention
The object of the present invention is to provide a kind of apparatus and method of distinguishing the above-mentioned type, with the diameter of high precision measure bar, this bar does not need around its longitudinal axis rotation, and is particularly suitable for measuring the diameter of anury bar thus.
This measurement is the device of the bar diameter of the tobacco industry particularly; Comprise one group of laser measuring device for measuring; This laser measuring device for measuring has a generating laser and a laser pickoff, and the collimated laser beam of generating laser emission certain width is characterized in that; Generating laser and laser pickoff are installed side by side; The mirror surfaces that generating laser and laser pickoff front end have two 45 degree to install, the laser beam that generating laser sends is received by laser pickoff through two secondary reflections smoothly, and measured bar is vertical with light is placed in the middle of the light path behind the first reflection.
Mirror surface can be a prism, also can be level crossing.
The utility model is through changing radiation direction, and measurement object is placed in the middle of the light path, because the covering effect of bar, receiver detects the shade size of this bar formation and produces the electric measurement signal of the diameter of this bar.Handling like this has a special benefit to be to reduce the distance of generating laser and laser pickoff, is particularly suitable for measurement mechanism installing space condition of limited.Such as the diameter of measuring at least two bars simultaneously, the optical measuring device of at least two preferred opposite disposed can be set, its each measurement mechanism is used to measure the diameter of bar.Such embodiment is particularly suitable in two bar machines.
For measuring not round anury bar; Measurement mechanism self is rotatable; Its pivot is the measurement object longitudinal axis, and this is desirable situation certainly, in the measurement light path that measurement object is placed, can not be entirely on the center in fact; But do not influence measurement result with a less-than-ideal longitudinal axis rotation, do not need centering because photoelectric conversion device only judges the shade size.
In fact measuring process in; Because shaft is in operation continuously; So what the measurement mechanism of rotating operation was measured is not the same cross section of shaft; But measurement mechanism will measurement result be judged as the repeatedly measurement on the cross section, and comes arithmetic average diameter and out-of-roundness with this.This is because the production technology of plume processing machine has determined the cross section of shaft that unexpected variation can not take place, and can regard the shaft of certain-length as a unified shape of cross section.
