Description

Measurement device and measuring method, for the manufacture of the machine of filter stick, for the manufacture of the machine and equipment of multi-segment filter product

Technical field

The present invention relates to a kind of measurement device of the filter stick portion section for tobacco industry, comprise the optical measuring device for detection of the characteristic of the filter stick portion section of carrying along Y.In addition, the invention still further relates to a kind of corresponding measuring method, a kind of machine for the manufacture of filter stick, and a kind of machine and equipment for the manufacture of multi-segment filter product.

Background technology

In cigarette industry, occurred using more and more the trend of multi-segment filter, this multi-segment filter is manufactured with slivering technique in so-called multi-segment filter maker.For example, by EP 1 427 299 B2 known applicant's the multi-segment filter maker that is called MERLIN.The continuous filter rod that the filtration mouth section by different must be formed in this method is cut into filter tip piece at preposition place, and this filter tip piece is for example installed on cigarette subsequently on filter tip fitting machine.At this, the accuracy of cutting position is conclusive quality standard.In multi-segment filter maker, concerning the position of the cutting of carrying out, used regulating loop, the actual value of this regulating loop is determined by optical measuring device.For example be used for the optical measuring device of the cutting equipment of controlling multi-segment filter maker by EP 1 557 100 B1 cicada.But, filter mouth section some combinations, particularly Bai-Bai-combination of filtrations mouth section does not provide enough contrast difference/poor contrast, thereby each filtration mouth section can not be distinguished by optical measuring device.In this case, the cutting equipment of multi-segment filter maker can not utilize the precision of expectation to regulate.

Summary of the invention

The object of the invention is to, propose a kind of measurement mechanism, a kind of filter manufacturing machine, a kind of multi-segment filter maker, a kind of equipment and a kind of measuring method, they have been realized and have determined more reliably particularly product performance to be measured in the case of a little less than filtering the contrast of mouth section combination.

The present invention utilizes the feature of independent claims to realize described object.The painted assembly to filter stick portion section of the optical absorption by utilizing the remarkable light that has changed optical measuring device dyes, the characteristic to be measured of the filtration mouth section that can be colored with sufficiently high quality measurement by means of optical measuring device, particularly position vertically.Particularly can obviously increase the contrast between different filtration mouth sections, and obviously improve thus quality or the precision of the measurement of being undertaken by optical measuring device.Consequently, even particularly a little less than the contrast of filtering the combination of mouth section time, for example, when the combination of Bai-Bai-filtrations mouth section, this has allowed the cutting position adjusting of the precision with expectation.

Optical measuring device is particularly measured in visible wave-length coverage.In the time that optical measuring device is measured in the wave-length coverage around measurement wavelength, painted preferably have one and measure the visibly different wavelength of wavelength.With measure visibly different painted meaning of wavelength, painted wavelength advantageously with measured wavelength offset 50nm at least, preferably 100nm at least.In the application's framework, wavelength can be regarded as the wavelength in air or in vacuum.In particularly preferred embodiments, relate to the painted of a kind of and the complementation of measurement wavelength.In this case, measuring contrast maximizes due to painted.Painted be at least preferably monochromatic and/or uniformly in the region of being detected by measurement mechanism.

The present invention also comprises painted conventionally, this painted can sign by means of dyestuff wavelength, for example grey painted.Important is only, compared with assembly undyed, particularly white, and the painted marked change that has particularly caused being equipped with the dyeing filter stick of assembly or the optical absorption of filter stick portion section in visible wave-length coverage.Optical measuring device is also not limited to monochromatic light or the narrow wave-length coverage around measurement wavelength.For example, optical measuring device can use white light.

In actual embodiment, the measurement wavelength of measurement mechanism for example can be positioned at red wave-length coverage and be 630nm at least.In this case, painted wavelength be preferably to the maximum 580nm and preferably 420 and the scope of 580nm in, more preferably 450 and the scope of 550nm in.In especially preferred embodiment, painted color is cyan (about 490nm) or the color (± 25nm) adjacent with cyan.Preferred alternative is the blue dyes with the wavelength that is less than 490nm, and for example indigo pigment, as indigo madder red (Indigokarmin) or indigo (Indigotin).

Concerning according to of the present invention painted, consider to filter the different assemblies of mouth section, particularly pack paper tape, glue impression, packing material, as acetate fiber or softening agent, as glyceryl triacetate.Preferably, the assembly that filters mouth section is colored in a kind of scope, and this region is on finished product, particularly can not see from outside on cigarette.Guarantee in this way the painted interference not forming consumer.To the dyeing of packing paper tape in the situation that, this point advantageously realizes by following manner, only dyeed in the whole inner side of inner side, preferred packaging paper tape, and the outside of packing paper tape keeps not being colored.

In the filter stick that optical measuring device is advantageously carried on filter rod or at Y with transmission method or filter stick portion section, measure, and preferably include LASER Light Source and optical receiver, this optical receiver has lens or photosensitive sensor.For example, by EP 1 557 100 B1 known applicant's this optical measuring device that is called MPC-sensor, the disclosure of EP 1 557 100 B1 is all containing in this application.
