Description
The present invention relates to the control of the optics of tobacco processing industrial products and relate to a kind of device that optics is controlled this series products and comprised imaging mechanism that is used for.
The tobacco processing industrial products product object in other words that can be understood as particularly clavate and bar shaped within the scope of the invention, as cigarette, filtering rod, multistage filtering rod, cigarette paper or seal paper, and sign printed words on the paper web face or the gluing on the paper web face.In optics control usually to the qualitative character of tobacco processing industrial products, as the existence of hole, length, object evaluation, sign, gluing, stain size, filter element, degree of impairment etc.
Usually use line by line scan formula camera or matrix form camera in order to carry out optics control.Since to image quality and resolution quality what require the assembling of these cameras is expensive macro lens.For example for whole length undistorted and that do not observe cigarette, the measurement thing must be very big to the distance of camera with damaging sharpness.Several positions at the machine of tobacco industry must repeatedly fold as the light path that has minute surface on the filter tip fitting machine.In addition, at many positions of filter tip fitting machine owing to the reason of the geometric configuration condition precedent in this machine does not have optics control.
The measurement thing illumination of product in other words to tobacco industry is to be realized by independent light source, owing to must have high light intensity to big these light sources of distance of object.Wherein also disclosing when loss of strength is arranged makes light near measuring thing with fiberguide cable.The particle that dances in the air, for example tobacco dust disturb optics control and the possibility of the assessment that leads to errors big, and this possibility can only just can lower by adopting expensive measure because the distance of the control device that is adopted is big.
By comparison, task of the present invention provides a kind of device that is used for tobacco processing industrial products is carried out optics control of compact conformation, and obviously reduces the influence disturbed when this series products being carried out optics control.
This task is accomplished by a kind of application that tobacco processing industrial products is carried out the gradient index lens of optics control.
Gradient index lens refers to a kind of parts of printing opacity within the scope of the invention, and it produces a kind of lensing by continuous variations in refractive index.The complicated shaped surface light beam of replacement part in traditional lens is the incident flat surfaces preferably.These light beams are deflected in gradient index lens continuously, focus in a focus at last.Refractive index preferably changes transverse to optical axis in this case.Gradient index lens can design very for a short time, and particularly can have very little diameter.In addition, length of lens can be regulated with changing, and mainly is that focal length and operating distance can be very near from the end of gradient index lens.For example by selecting the length of lens plane of delineation can be located immediately on the smooth surface of lens suitably, light source just can directly paste on the lens like this.Particularly also can will design to the focal length for the treatment of the product that optics is controlled or be provided with very closely from the preferably smooth surface of gradient index lens, thereby, because lens are very near to product to be controlled, have only seldom particle to having controlled interference effect, particle has the space of existence because have only seldom in the distance between lens and product to be controlled in other words to be measured.
If using a plurality of then is effective especially with a gradient index lens that is listed as setting at least side by side, particularly.Just can control the quality of clavate and strip like article and other characteristic in this case with simple method and mode.In addition, use a gradient index lens for tobacco processing industrial products is thrown light on, then the part of the responsible product illumination of optical control device also can be a minor structure.Then produce especially effectively illumination if use a plurality of gradient index lens side by side, that particularly become row to be provided with to be used for illumination.
In addition, this task is also carried out optics control by the product to tobacco industry, and comprises that the device of an imaging mechanism is accomplished, and wherein, this imaging mechanism comprises at least one gradient index lens.Because the structure of gradient index lens is very little,,, realizes in such device so can saving ground, space very much also because adjustable focal length is very little, and the respective end of gradient index lens is very little to the distance of focus in other words.Preferably this imaging mechanism comprises a plurality of gradient index lens side by side, that particularly become row to be provided with.By this measure can to the article of clavate or bar shaped in other words product effectively control.
In addition, if imaging mechanism comprises delegation's photodiode or the CCD of delegation, then can simply also can save ground, space and take the article image of product in other words that writes down tobacco industry in other words.CCD is capable, and itself is open.Abbreviation CCD is derived from well-known notion Charged-Coupled Device (charge coupling device).Use special especially CCDs in the present invention.Wherein, half of the parts that are provided with in CCD will be transformed into the load capacity relevant with intensity with focusing on lip-deep image pointwise, and second half is used for storage and sense information.CCDs is as imageing sensor in this respect.
Preferably imaging mechanism comprises the mechanism that image that will collect and the image that can predesignate compare.Can carry out optics control effectively to product by this measure.For example when filter tip or cigarette with filter tip are controlled, can store by the filtering cigarette that filter tip up to specification is up to specification in other words, and the cigarette with filter tip that they and filter tip to be controlled is to be controlled in other words clap image compare.Control to multi-segment filter is effective especially.For example as long as too big difference occurs in intensity distributions, these products that obtain corresponding control are will be in the processing that continues disallowable to come out.The mechanism that the image that obtains and the image that can predesignate are compared is computing machine preferably.This computing machine can be stored the image that can predesignate in a memory unit, and this image and captured image can be compared by this computing machine, wherein, also can produce a control signal then, this product of this signal indication is up to specification or represent that this product is unsatisfactory.
If lighting device with light source is set and the light of this light source is directed to the gradient index lens of product to be controlled, then this lighting device also can be saved ground, space and realizes very much.If a plurality of gradient index lens arranged side by side, that particularly become row to arrange are set then throws light on effective especially.
Within the scope of the invention side by side, particularly become row setting also to be called array setting among Fig. 3, also will narrate below this set.If the focal point settings of gradient index lens perhaps is provided with the next door of its end in the end of gradient index lens, and is then effective especially according to the use of device of the present invention.By this measure can farthest avoid since around the particle that dances in the air, the measurement inexactness or the wrong assessment that are caused as the tobacco dust.
Preferably the machine of tobacco industry comprises the device of the product of tobacco industry being controlled according to of the present invention.
In a kind of particularly preferred embodiment of the machine of tobacco industry, particularly filter stick or cigarette X ground are from a plurality of gradient index lens bypass mistakes that are set up in parallel.
