Definitions

  • This invention relates to a machine and a method for processing a web of material for the tobacco industry.
  • the invention addresses the processing of webs of material for the tobacco industry, such as, for example: tobacco, wrapping material, paper, filter material (e.g., PLA) etc.
  • the webs are typically wound in rolls which are unwound to feed the webs along a feed path on which suitable guide means and/or transfer means and/or processing units are located to allow processing the web to make semi-finished products used in the production of articles for the tobacco industry.
  • articles for the tobacco industry is used generally to denote rod-shaped articles such as, for example: cigarettes (traditional or heat not burn), cigars, cigarillos and the like.
  • the invention is applicable in particular to machines for processing webs of wrapping material or webs of tobacco, for example, of pre-treated, reconstituted or homogenized tobacco supplied in rolls.
  • Processing the webs may include, for example, cutting the web transversely or longitudinally.
  • Processing the web involves initially loading the web of material to start the production process.
  • the web is typically supplied in rolls from which the web must be unrolled to make the web follow a predetermined feed path by way of a plurality of rollers, guide means, transfer means and other processing devices.
  • the web is unwound and fed automatically and uninterruptedly from the roll along the feed path.
  • the web tears or is irreversibly damaged In such situations, the machine process is necessarily brought to a stop to allow the operator to identify the zone where the web has been torn or damaged and to feed the web manually along the feed path again, downstream of that zone and all the way to the processing zone.
  • the operator may also need to cut off a damaged or torn portion of the web before re-threading and guiding the web along the means/rollers/devices defining the stretch of the feed path downstream of the zone where the web was torn or damaged and all the way to the processing zone.
  • This kind of machines can be found in US4646986 .

  • the retaining device is capable of automatically holding and guiding the end portion of the web along the entire feed path "P" (full round of web) or only a part of it (the stretch of the feed path "P" remaining to reach at least the processing unit).
  • the invention also provides a method for processing a web of material for the tobacco industry, comprising a step of unwinding a web of material for the tobacco industry along a feed path "P" and a step of processing the web along the feed path "P".

  • a buffer 30, configured to define a reservoir/storage unit of the web 2 unwound from the unwinding unit 10, is interposed between the unwinding unit 10 and the processing unit 20 along the feed path "P".
  • the buffer 30 makes it possible for production to continue in the event of a shutdown in the unwinding unit 10 or in the processing unit 20, for example to carry out maintenance or to change the roll 11.

  • the guide mechanism 40 might, however, comprise more than one arm 43: for example a guide mechanism defined by an arm-coupling sequence.
  • the first axis of rotation "X" is perpendicular to the trajectory "T" (that is, to the guide 51) and, still more preferably, horizontal.
  • the arm 43 can rotate about the coupling 44 so that, in practice, it can move the retaining device 41 towards or away from the feed path "P" in such a way as to allow guiding the web 2.
  • the arm 43 can be rotated to a retracted position (illustrated in Figure 2 ) where it does not interfere with the units 10 and 20 as the web 2 moves along the feed path "P".

  • the machine 1 comprises a vertical supporting wall 1a to which the unwinding unit 10, the processing unit 20 and, preferably, the buffer 30 are cantilevered, and the feed path "P" lies substantially in a first position plane parallel to the vertical supporting wall 1a at a first distance from the vertical supporting wall 1a, and the trajectory "T" (that is, the guide 51) lies in a second position plane parallel to the vertical supporting wall 1a at a second distance from the vertical supporting wall 1a, greater than the first distance.
  • the guide mechanism 40 can advantageously be translated along the guide 51 and the arm 43 can rotate about the first axis of rotation "X" in a vertical plane parallel to the vertical supporting wall 1a to move the retaining device 41 towards or away from guide and/or transfer and/or processing means of the unwinding unit 10 and/or of the processing unit 20 and/or of the buffer 30.
  • the retaining device 41 comprises a gripper 41a (as illustrated in Figure 3 ) or a pneumatic suction device, to hold the web 2.

  • the machine 1 preferably also comprises a control and drive unit, not illustrated, connected to the detecting means and configured to selectively drive the guide mechanism 40 when the change in the tension of the web 2 along the feed path "P" and/or the integrity of the web 2 along the feed path "P" does not fall within predetermined criteria of acceptability.
  • a control and drive unit not illustrated, connected to the detecting means and configured to selectively drive the guide mechanism 40 when the change in the tension of the web 2 along the feed path "P" and/or the integrity of the web 2 along the feed path "P" does not fall within predetermined criteria of acceptability.
  • the machine 1 is advantageously able to detect faults in the unwinding system of the web 2 and to take action on the guide mechanism 40 accordingly.
  • the machine 1 preferably also comprises a cutting device which is selectively activable by the control and drive unit and which is configured to cut the web 2 transversely in a zone of the web 2 where the change of tension was detected.

  • the step of retaining and guiding the web 2 is accomplished by retaining the end portion 2a of the web 2 mechanically or by pneumatic suction.
  • the method comprises a step of automatically moving a retaining device 41 of the guide mechanism 40, configured to retain the end portion 2a of the web, towards the end portion 2a of the web 2 in such a way that the retaining device 41 can automatically engage the end portion 2a to implement the step of retaining.
  • the method allows automating the process of initial threading, as well as any other operation on the feed path "P", rapidly and efficiently thanks to the smart system of moving the retaining device 41.
  • a possible alternative embodiment of the method of this invention may comprise a step of an operator manually delivering the end portion 2a of the web to the retaining device 41. That way, the process of initial threading or maintenance operation is carried out semi-automatically; once the operator has delivered the end portion 2a of the web 2 to it, the retaining device 41 can proceed to automatically guiding the web along the feed path "P".
  • the method also comprises a step of detecting a change, if any, in the tension of the web 2 along the feed path "P" and/or the integrity of the web 2 along the feed path "P", compared to predetermined reference values, followed by a step of selectively driving the retaining device 41 to implement the step of retaining, when the value of the change does not meet given acceptability criteria.
  • the method thus allows prompt and precise maintenance action to be taken on the machine 1.
  • the method may also comprise a step of cutting the web 2 transversely in a zone of the web 2 where the change in tension was detected.
  • This invention achieves the preset aims, overcoming the disadvantages of the prior art, by providing a machine and a method for processing a web of material for the tobacco industry, capable of improving the efficiency of the production process by proposing operating solutions ensuring that the web is correctly fed along the feed path, thereby increasing the level of automation while reducing down time and costs.
