Description

Make the method and apparatus of tobacco smoke filters
Quoting of related application
The application requires in the priority of the 60/744th, No. 995 U.S. Provisional Patent Application that is entitled as " method and apparatus of making the multistage tobacco smoke filters " of submission on April 17th, 2006; And require in the priority of the 60/887th, No. 960 U.S. Provisional Patent Application that is entitled as " method and apparatus of making tobacco smoke filters " of submission on February 2nd, 2007; Its full content is introduced the disclosure as a reference.
Background of invention
Some tobacco smoke filters comprises multiple filter sections, wherein a kind of section is the standard filter (" standard paragraphs ") that comprises the cellulose acetate filter material, and other section (segment) or section (segments) comprise one or more other additives (" non-standard segment ").The example of other additive like this comprises flavor enhancement, and comprises that selectivity reduces the amount of potential harmful components in the tobacco smoke or the material of toxicity, as activated carbon granule.When tobacco smoke filters comprises such as two sections multisection filtering device, standard paragraphs is arranged on the near-end of the smoking product that contacts with smoker's lip usually, non-standard filter sections (segment) or section (segments) are arranged on the far-end of smoking product usually, the tobacco section of next-door neighbour's smoking product, that is, between standard paragraphs and tobacco section.
Only have the production of standard single hop cellulose acetate tobacco smoke filters to relate to high-speed equipment, it is processed into cellulose acetate tow the standard filter stick under the variable bit rate of height to 500 meter per minute.More specifically, all basically tobacco smoke filters are made " filter rod forming " machine (" rod maker " machine) the manufacturer's standard single segment tobacco smoke filter of commercial city with standard, and described machine can easily obtain from many manufacturers.Filter rod forming machine is peeled off cellulose acetate tow from the compressed package of machine one side continuously.Tow comprises about 10,000 the parallel single fibers of as many as, and described fiber crimp becomes bulky tow and is compressed into big bag.Then when entering filter rod forming machine with the parallel flat board that expands into defibre of tow, described filter rod forming machine makes final filter become the fiber of homogeneous density easily when fiber forms filter stick, but also preparation is used for the tow of application of triacetin.Then, tow is by having the coating element of adding a cover chamber, and there, brush rotates in the dish of glyceryl triacetate, makes triacetin droplets suspend in air, thereby tow is exposed in the droplet of glyceryl triacetate.Glyceryl triacetate is a plasticizer, and it is crosslinked with cellulose acetate fibre in tow, so that give the hardness that strand material further adds man-hour.Then, will be fed to by the tow that glyceryl triacetate is sprayed in the funnel that makes its formation standard tow clavate shape.Then, twine two rods of standard with paper tape, and seal paper tape with hot glue when rod enters cutter unit by funnel, in described cutter unit, the rod that paper tape twines is cut into standard filter sections.After the cutting, standard filter sections is fed in the groove on the rotor, described rotor is discharged into standard filter sections on the conveyer belt and adheres to tobacco segment to form the zone of complete smoking product so that be sent to.
Yet, comprise the equipment of the other costliness of the production needs of smoking product of multisection filtering device or the standard production method and apparatus of production standard single hop filter made a lot of expensive changes.For example, the method of producing multisection filtering device smoking product at present comprises: the filter rod forming machine that 1) uses two kinds of separation, every kind all has sprayer unit and cutter unit, so that the rod of the rod of manufacturer's standard filtering material and non-standard filtering material and each rod of machine cuts are that the standard filter sections and the length of ultimate criterion filter sections twice is the non-standard filter sections of final non-standard filter sections twice with production length independently; 2) use at the industrial machine that is called as " combiner " at a high speed double length standard filter sections and the combination of double length non-standard filter sections machinery to form the rod of multisection filtering device, for example twine standard filter sections alternately and non-standard filter sections and the section that will replace sticks together with paper; 3) rod of cutting combination contains the multisection filtering device of standard filter sections and non-standard filter sections with manufacturing; And 4) multisection filtering device is adhered to the smoking product of finishing with manufacturing such as the tobacco segment of cigarette or cigar.
Referring now to Fig. 1, it illustrates a kind of schematic diagram of some step of method of production multisection filtering device smoking product of present use, and described smoking product for example has the smoking product of two sections filters.Can find out from Fig. 1, at first make the rod 10 of the standard filter material of separating and the rod 12 of non-standard filter material.Then, cut the standard filter sections 14 of the rod 10 of each standard filter material, and cut the non-standard filter sections 16 of the rod 12 of each non-standard filter material with the generation double length with the generation double length.Then, the standard filter sections 14 of double length and the non-standard filter sections 16 of double length are combined into multistage rod 18, and at the cutting of the position shown in 19 multistage rod 18, to obtain having the right rod 20 of two sections filters that connect together.Then, as shown in the figure, tobacco segment 22 is adhered to each end of the right rod 20 of two sections filters that having of incision connect together.Cut the right rod 20 that adheres to two sections filters that having of its each end connect together with tobacco segment 22 from central authorities 24 as shown in the figure then, to obtain final smoking product 26, it has the multisection filtering device 28 on tobacco segment of adhering to 22.
Can understand, this manufacturing comprise multisection filtering device the smoking product method than the standard method complexity of making the smoking product have only single standard section filter many.In addition, except the standard filter rod forming machine, this method needs expensive equipment.
Therefore, need the method for making the smoking product that comprises multisection filtering device badly, it does not need the complex steps of present method therefor, does not need the expensive additional devices except that the standard filter rod forming machine yet.
