Definitions

  • the present invention relates to a packer machine and a wrapping method for the production of pouches, each containing a portion of a loose product (i.e., a non-compact product) and an object.
  • a loose product i.e., a non-compact product
  • a snus pouch has a rectangular shape and exhibits a longitudinal sealing and a pair of transverse sealings.
  • an aromatic capsule within a snus pouch there may be (at least) one additional solid object, e.g., an aromatic capsule, an aromatic pellet (i.e., a granular agglomerate in the shape of an ovule or small cylinder), one or more aromatic strips, or one or more aromatic threads.
  • an aromatic capsule is generally spherical in shape and comprises a breakable outer shell containing an aromatic liquid substance therein: by breaking the outer shell (typically by crushing between fingers) the aromatic liquid substance exits to flavor the snus.
  • a known packer machine for the production of snus pouches is of FFS (Form, Fill and Seal) type and comprises: a conveyor device to convey a wrapping material band along a packing path; a wrapping station arranged along the packing path and where the wrapping material band is wrapped to form a tubular wrap having a longitudinal development around a wrapping duct; a longitudinal sealing unit to longitudinally seal the tubular wrap at an overlapping zone of the wrapping material band; a loose material feeding device for successively feeding the loose product portions inside the tubular wrap; a transverse sealing unit to transversely seal the tubular wrap so as to form an alternating succession of sealing zones and zones containing a portion of loose product; and a cutting unit to transversely cut the tubular wrap at the sealing zones so as to separate the individual snus pouches.
  • FFS Form, Fill and Seal
  • the feeding device ends at the inlet of the wrapping duct (around which the wrapping material is folded to form the tubular wrap) and "shoots" the portions of loose product into the tubular wrap through the wrapping duct by means of compressed air.
  • a packer machine and a wrapping method for the production of pouches each containing a portion of a loose product and an object are provided according to what claimed in the appended claims.
  • reference numeral 6 indicates, as a whole, a packer machine which produces snus pouches 1.
  • the packer machine 6 comprises a frame resting on a floor and exhibits a vertical support wall (the "front” wall of the packer machine 6 and coincident with the plane of Figure 2 ) onto which all operating components contributing to the production of snus pouches 1 are mounted.
  • the packer machine 6 comprises a (partially illustrated) conveyor device 7 for conveying a wrapping material band 8 (preferably consisting of non-woven fabric) along a straight packing path P.
  • a wrapping station S 1 is arranged along the packing path P in which the wrapping material band is wrapped to form a tubular wrap having a longitudinal development.
  • a longitudinal sealing unit 9 is arranged along the packing path P and downstream of the wrapping station S1 to longitudinally seal the tubular wrap at an overlapping zone of the wrapping material band to make the longitudinal sealing 3.
  • a transverse sealing unit 10 is arranged along the packing path P and downstream of the longitudinal sealing unit 9 to transversely seal the tubular wrap so as to form an alternating succession of sealing zones (at the transverse sealings 4) and zones containing a loose product portion 2 and an object 3.
  • a loose material feeding device 11 is arranged at the wrapping station S1 to successively feed the loose product portions 2 inside the tubular wrap and an object feeding device 12 to successively feed the objects 3 inside the tubular wrap.
  • a cutting device 13 is arranged along the packing path P and downstream of the transverse sealing unit 9 to transversely cut the tubular wrap at the sealing zones (i.e. the transverse sealings 4) so as to separate the individual snus pouches 1.
  • the feeding device 11 comprises a feeding drum 15 which rotates with an intermittent law of motion (i.e. exhibiting a cyclic alternation of motion and rest phases) about a horizontal rotation axis 16 (perpendicular to the plane of Figure 2 ).
  • the feeding drum 15 is coupled to a suction source at a loading station S2 where the feeding drum 15 receives the loose material and is coupled to a compressed air source at a feeding station S3 where the feeding drum 15 (through compressed air jets) directs the individual portions 2 of loose material into the wrapping duct 14.
  • a continuous bead of loose material (due to the effect of the suction source) is progressively formed on the shell of the feeding drum 15; the continuous bead of loose material is conveyed to the feeding station S3 where, due to the effect of the compressed air source, the portions 2 of loose material are separated from the continuous bead and transferred along the wrapping duct 14 until they enter the wrapping material band 8 folded in a tubular shape around the wrapping duct 14.
  • the feeding device 12 is configured to feed the objects 3 into the wrapping duct 14 so as to arrange in the wrapping duct 14 each object 3 between two adjacent portions 2, i.e. so as to arrange in the wrapping duct 14 each object 3 in a corresponding gap 18 dividing two adjacent portions 2.
  • the feeding device 12 is configured to arrange each object 3 in the wrapping duct 14 in contact with a head (i.e., an initial/front part) of a portion 2 relative to an advancement direction of the portions 2.
  • the feeding device 12 is configured to arrange each object 3 in the wrapping duct 14 in contact with a tail (i.e.
  • the displacement speed of the seats 21 i.e., the peripheral speed of the feeding drum 19
  • the displacement speed of the seats 21 is (essentially) identical to the displacement speed of the portions 2 along the wrapping duct 14, and thus when an object 3 arrives in the wrapping duct 14 from the feeding drum 19 it has its own displacement speed similar to the displacement speed of the portions 2 along the wrapping duct 14, and thus it can fit with less mechanical stresses and more accuracy into the respective gap 18 between two adjacent portions 2.
  • the two seats 21 are spaced apart by an arc of a circle having a length D (illustrated in Figure 3 ) equal to a distance D (illustrated in Figures 4 and 5 ) existing between two successive portions 2 which are located in the wrapping duct 14.
  • the feeding device 12 comprises a feeding duct 22 originating near the periphery of the feeding drum 19 and at the output station S5, leads into the wrapping duct 14 and is travelled by the objects 3 to enter the wrapping duct 14. That is, the wrapping duct 14 has a through opening 23 arranged at the top (i.e. at an upper wall of the wrapping duct 14) into which the feeding duct 22 flows to make the objects 3 enter the wrapping duct 14.
  • the feeding duct 22 forms an acute angle (generally between 10° and 20° and not greater than 30°) with the wrapping duct 14 such that the main (prevailing) component of the motion of the objects 3 travelling through the feeding duct 22 is parallel to the packing path P followed by the portions 2 along the wrapping duct 14.
  • the feeding device 12 comprises (at least) a blowing device 24, which is arranged at the output station S5 and is configured to emit a compressed air blast, which extracts an object 3 from a seat 21 of the feeding drum 19 and pushes the object 3 along the feeding duct 22 and towards the wrapping duct 14.
  • a single blowing device 24 that is common to all the seats 21 is provided for and is always stationary in the output station S5 (i.e. it does not rotate together with the feeding drum 19); according to a different embodiment, a plurality of blowing devices 24 are provided for, each of which is mounted onto the feeding drum 19 (thus rotates together with the feeding drum 19) and is coupled to a single seat 21.
  • the feeding device 12 comprises a hopper 25 which is arranged above the feeding drum 19 and contains a mass of objects 3 and ends with a vertical channel along which a row of objects 3 falls by gravity to the input station S4.
