Definitions

  • This invention relates to a method and an apparatus for processing a web of wrapping material used to make smoking articles. More specifically, this invention relates to a method and an apparatus for making rod-shaped smoking articles.
  • rod-shaped articles is used herein to denote products such as, for example, cigarettes, cigars, cigarillos, electronic cigarettes and related semi-products but also semi-products (for example, filters and portions for releasing a substance to be inhaled). Background art
  • cigarette is used to denote any rod-shaped article comprising at least a filter, a cigarette segment designed to release an inhalable substance, and a connecting strip disposed in such a way as to connect the filter and the cigarette segment to each other.
  • the cigarette may be a traditional cigarette, where inhalation follows burning the free end of the cigarette segment, or it may be an electronic cigarette, where inhalation follows heating (without burning) the free end of the cigarette segment (specifically, with a carbon tip).
  • the cigarette segment may comprise traditional tobacco wrapped in paper or it may be an aerosol-generating element, that is,
  • the tobacco may be, for example, pre-treated, reconstituted or homogenized tobacco.
  • rod-shaped articles of the type mentioned above comprise a wrapper - of paper, for example - in which the articles are wrapped.
  • the machines which make the rod-shaped articles therefore, typically include rolls of wrapping material of various kinds which are unwound into continuous webs and then processed, if necessary, and used, for example, to make connecting strips for the cigarettes or coverings for the continuous rods of tobacco or filter material to make the filters or the cigarette segments.
  • Web processing may comprise applying features such as a commercial logo (by embossing), knurling on the paper (also by embossing) and, in the case of electronic cigarettes (with carbon tip) an inner layer of metallic material.
  • US6543457 discloses a cigarette making method in which a surface of a running paper web is provided with a pattern and a marker disposed near the pattern.
  • the method comprises detecting the marker (which can be detected more easily than the pattern) using sensors, so as to adjust the conveying speed of the paper web through a cutting unit for cutting the paper web, based on the detections performed.
  • the method described has one drawback, however. More specifically, the method described has the drawback of using both the pattern and the marker as a reference; since the pattern on the surface of the web may be incorrectly positioned (due to errors when it is applied), adjusting the cutting operation based (also) on the pattern may have a negative effect on the cutter, making cutting imprecise.
  • US2016120214 discloses a method for making cigarettes comprising a wrapping material which in turn comprises an additive used to control cigarette burning.
  • the method comprises detecting, with a sensor, one or more marks applied on the surface of the wrapping material which, after wrapping, is the surface that is visible to the user.
  • the marks are used to synchronize the cutting of the tobacco segment with the concentration profile of the additive on the wrapping material.
  • This method has several drawbacks: in particular, positioning errors may occur (during the step of applying the marks); these mark positioning errors lead to imprecise cutting of the tobacco segment and have a negative effect on subsequent processes.
  • the aim of this invention is to provide a method and an apparatus for processing a web of wrapping material used to make smoking articles to overcome the above mentioned drawbacks of the prior art.
  • this invention has for an aim to provide a method and an apparatus for processing a web of wrapping material where a mark can be positioned in a particularly precise and reliable manner using a manageably sized, easy to make system (which can be applied on newly made machines or retrofitted on existing machines). Further aims of the invention are to provide a web of wrapping material and a method and an apparatus for making smoking articles.
  • the method comprises a step of feeding the web of wrapping material.
  • the web advances by a predetermined quantity (i.e., length).
  • the predetermined quantity corresponds to a length of a stretch of web used to make a single cigarette.
  • the web is fed continuously.
  • the method comprises a step of making a feature (at least one) on the web.
  • the method comprises a step of applying a mark on a surface of the wrapping material.
  • a mark may be, for example, a notch made on the wrapping material in order to control subsequent operations.
  • buffers may be provided which involve temporarily stopping the feeding of the articles; it is therefore necessary to detect each article as it enters the machine (or machines), or after it has entered, so as to be able to program the subsequent operations. And it is the marks made on the articles that are used for the purpose of detecting the articles.
  • the steps of feeding, of making a feature (at least one) on the web and of applying a mark are repeated cyclically with a predetermined periodicity.
  • the method comprises a step of generating a synchronization signal.
  • the synchronization signal represents the periodicity.
  • the synchronization signal is generated by a timer. In an embodiment, the synchronization signal is generated at regular intervals. Using the timer, the duration of the regular time intervals can be set as a function of the required periodicity (for example, based on the size of the smoking articles to be made).
  • the mark is applied by means of a shaft controlled by the synchronization signal. That way, each mark is spaced from the next by a predetermined distance.
  • the marking shaft is configured to make each mark at a respective instant, determined by the synchronization signal; the time interval between the instants one mark and the next are made, governed by the synchronization signal, determines the distance (on the web) between that mark and the next.
  • controlled shaft or “shaft” is used to mean an actuator (for example, an electric motor) controlled by the control unit and connected to a movable element to drive it; that way, a given movement is measured (for example by an encoder or another sensor) and controlled by the control unit through the actuator, in such a way that a tool can be positioned precisely at an arbitrary point along its stroke.
  • actuator for example, an electric motor
  • the (at least one) feature on the web is controlled by the synchronization signal.
  • the processing shaft is configured to make each feature at a respective instant, determined by the synchronization signal; the time interval between the instants one feature and the next are made, governed by the synchronization signal, determines the distance (on the web) between that feature and the next. Further, if both the marking shaft and the processing shaft are controlled by the synchronization signal, that synchronization signal determines the distance (on the web) between each mark and each respective feature.
  • the synchronization signal which controls the position of the mark, it is possible to position the mark repeatably with a very high degree of precision both relative to the preceding and the following marks and relative to the other features made on the web (and also controlled by the synchronization signal.
  • the step of applying the mark is carried out on an inside surface of the wrapping material.
  • inside surface of the wrapping material is meant the surface which is intended to face the inside of the corresponding article when the article has been completed.
  • the outside surface is the surface opposite to the inside surface and intended to face the outside of the corresponding article when the article has been completed.

Preferably, the mark is applied on the inside surface of the wrapping material. In an embodiment, the step of applying the mark comprises a step of inkjet printing (on the wrapping material). In an embodiment, the step of applying the mark comprises a step of laser engraving (the wrapping material).
  • the step of making a feature (at least one) includes (a sub-step of) applying a logo.
  • the logo is applied on at least one surface of the wrapping material (preferably the outside surface).
  • the logo is applied by (a first step of) embossing the wrapping material.
  • Each logo thanks to the synchronization signal which governs its application, is spaced from the next by a predetermined distance.
  • the step of making a feature includes (a sub-step of) embossing a surface of the wrapping material to create a knurled portion.
  • first step of embossing is meant the process by which the logo feature is applied
  • second step of embossing is meant the process by which the knurled portion is made.
  • the (second) step of embossing is carried out both on the inside surface and on the outside surface of the wrapping material.
