Definitions

  • the present invention relates to a device for positioning natural or artificial tobacco leaves on a cutting dieplate and for transferring cut leaves from said die-plate to units for rolling wrapper leaves around rod-shaped smoking products.
  • the cigars or cigarillos of certain types are provided with a wrapper, the outer and visible border of which is located along a generator-line of the product.
  • two zones can be determined in the cut wrapper leaf, namely a visible Zone and a covered zone.
  • the visible zone which must be free of any flaws must be at least equal in width to the length of the perimeter of that portion of product which has the largest crosssection. This zone is referred to as the geometric zone and is essential.
  • the second zone which is to be covered by the Wrapping material of the preceding zone does not have the same requirements in regard to either consistency, width or length.
  • the object which is contemplated is in fact to provide an additional wrapping width so as to permit of gumming and to provide the product with sufficient mechanical strength. Under these conditions, there will be no major disadvantage if the said second or underlying zone has holes or torn portions of leaf, if said zone does not cover the entire length of the smoking product, if said zone is of more or less small width or, finally, if the edge of the zone is of irregular shape.
  • the solution can consist in presenting the tobacco leaf in a movement which is the reverse of the precedent, that is to say, from the rear edge towards the front edge.
  • this solution is ruled out on technical and physiological grounds.
  • the solution proposed in the present invention consists in carrying out by mechanical means the reversal of the portion of wrapper leaf whenever this proves necessary, in such a manner as to ensure that the border which is formed by the front edge of the cutting profile in fact becomes the outer border which will terminate the rolling of the cigar.
  • a reversing motion as thus contemplated is necessary when the width of the leaf is sufficient to perform successive cutting operations in the longitudinal direction.
  • the device which is contemplated in accordance with the present invention must have interchangeable elements which make it possible to present the cut-out portion of leaf either along the front edge or along the rear edge.
  • the present invention is directed to a method for the utilization of tobacco-leaf fragments which are formed by cutting out on a die-plate for the purpose of wrapping rod-shaped smoking products, said method consisting in that the cutting line which corresponds to the visible border of the wrapper is located at the front of the die-plate.
  • the invention has for its object a device for transferring by means of a moving arm fitted with a suction unit pieces cut from tobacco leaves for subsequent use as cigar wrappers, characterized in that said device comprises means adapted to cause the transfer suction unit to pivot at will through angles having supplemental values and in opposite directions.
  • the pivotal means can comprise two interchangeable sets of sliding members and cams which are adapted to cooperate with each other.
  • the suction unit comprises means for producing suction through said suction unit.
  • Said suction means can comprise a cylindrical cup fitted with roller hearings in which is fitted a cylindrical sleeve secured to a flange in which an offset orifice communicates with the Suction pipe located within the moving arm.
  • FIG. 1 shows the transfer arm and stationary suction unit of the type provided on machines of conventional design, as shown respectively in position A above the cutting die-plate and in position B above the rolling apron.
  • FIGS. 2 and 3 are diagrams of the cutting die-plate which may be completely covered or not by a tobacco leaf.
  • FIG. 4 is a plan view of the complete device according to the invention.
  • FIGS. 5 and 6 are views in isometric perspective show ing two interchangeable sliding members.
  • FIG. 7 is an exploded isometric in projection of the different elements which constitute the movable heads of the suction unit.
  • the moving arm 1 is designed to move through the angle a between the die-plate and the rolling apron which corresponds to the respective positions A and B. Since the suction is stationary, the front edge 2 of the suction unit is located at 2' in position B after having moved through the same angle.
  • the moving arm 1 moves through the same angle at whilst the front edge 2 of the suction unit is intended to move through a different angle.
  • the moving arm 1 supports the movable suction unit 3.
  • the movement of rotation of the suction unit in a horizontal plane is produced by the displacement of a sliding member 4 which is secured thereto and guided by a flat cam 5 fixed to the frame of the machine.
  • the sliding member 4 can be replaced by a sliding member 6 (as shown in FIG. 6) which is guided by the cam 7 and the configuration of which is such that the suction unit will accordingly move through an supplemental angle and in the direction opposite to the movement effected by said unit as a result of the interaction of the sliding member 4 and cam 5.
  • the movable suction unit 3 is constructed in accordance with FIG. 7 in two sections.
  • the stationary section which is rigidly fixed to the extremity 13 of the moving arm 1 comprises a flange in which is formed an offset orifice 14 and a retaining ring 17.
  • the movable portion consists of the perforated plate and the body 11 of the suction unit, there being formed within said body a cup 15 in which are fitted roller-bearings 16.
  • the flange 12 and retaining ring 17 are placed on each side of the suction unit body 11 and are adapted to cooperate with a cylindrical sleeve 21 which is secured to the flange 12 so as to be applied in sliding contact with a slight friction against the roller-bearings 16 and thus ensure leak-tightness of the suction system.
  • the perforated plate 10 which can readily be disassembled for cleaning purposes, is secured to the body 11 by means of two lugs 18, one of which can be released by withdrawal of a stud 19 mounted in a spring-loaded pin 20.
  • the moving suction unit 3 is capable of carrying out at the end of the arm 1 and about the vertical axis thereof a movement of rotation through angles having supplemental values and in opposite directions.
  • the leaves can be positioned for the cutting operation relative to the rear edge 22 of the die-plate which is considered as a reference without thereby entailing the need to cover the nonshaded portion of FIG. 3 completely.
  • the rolling operation will be started from the border 23 and the reversal of the suction unit is obtained by the combined action of the sliding member 4 and the cam 5.
  • the orientation of the suction unit is defined by the positions 23 and 23' which are indicated in FIG. 4.
  • a device for transferring pieces cut from tobacco leaves for subsequent use as cigar wrappers comprising a moving arm pivotally mounted thereon around a vertical axis, suction means on said arm and means on the device for pivoting said arm through at least two different angles having supplemental values and opposite directions.
  • a device for transferring pieces cut from tobacco leaves for subsequent use as cigar wrappers comprising a moving arm pivotally mounted thereon around a vertical axis, suction means on said arm and two interchangeable sets of sliding members and earns cooperating with each other and mounted at will on said arm for pivoting said arm through at least two diiferent angles having supplemental values and opposite directions.
  • a device for transferring pieces cut from tobacco leaves for subsequent use as cigar wrappers comprising a moving arm pivotally mounted thereon around a vertical axis, a cylindrical cup mounted on said arm, roller bearings between said cup and said arm, a cylindrical sleeve, a flange on said sleeve having an oifset orifice, a suction pipe connected to said orifice, and means on the device pivoting said arm through at least two different angles having supplemental values and opposite directions.
