Definitions

  • the paper strips which receive the tobacco and form the rod are delivered in the form of reels, and therefore have a finite length.
  • the final segment of each strip of paper must be linked to the initial segment of the following strip each time the reel is changed.
  • these operations are carried out by means incorporated in the manufacturing machine and these means comprise devices, most of which are complicated, heavy and costly, without however ensuring complete automation of the replacement of a reel at the end of its stroke by a new full reel.
  • the two segments are held one above the other by superimposed devices, then connecting zones belonging to each of the segments are compressed, after which the segments are respectively cut into behind and in front of the connection zones.
  • the segment initial of the new strip is maintained at the time of the connection, coinciding with the final segment of the old strip by a pair of rollers between which the two strips are driven, and the pressure members are themselves two rollers rotating on their axes and between which pass the connecting zones of the segments.
  • the initial segment of the new band is fixed to a roller, above the final segment of the old band, then a punch is lowered against a base surface so that zones of liaion belonging to the final and initial two segments of the old and the new band are compressed and linked by interpenetration of matter. Then, the rear and front parts of the final and initial segments are cut.
  • the arrangement of the cutting blades is such that the risk of damage to the segment parts which must not be cut remains.
  • document GB-A-2189226 describes a method of end-to-end assembly of strips according to the preamble of claim 1.
  • the present invention results from a design of the sequence of operations to be carried out which differs from the various known solutions and from which follows the construction of a simple device, compact and operating precisely and reliably.
  • a first object of the invention is a method of end-to-end assembly of strips of paper of finite length for the continuous feeding of a machine, in particular for manufacturing cigarettes, in which a final segment of a first strip and an initial segment of a second strip are brought into relative positions of mutual overlap and connecting zones belonging to said segments are pressed against one another by a punch surface the final segment of the first strip is fixed relative to a base surface, then cut along a line situated behind its connection zone, after which the cut part of the segment is eliminated, and the initial segment of the second strip is brought opposite said segment end of the first strip, characterized in that a zone for fixing the initial segment of the second strip, situated behind the cutting line of the first strip, is fixed relative to the base surface, and the punch surface is moved against the base surface, for said pressure of said segments therebetween.
  • Another object of the invention is a machine for implementing the method according to claim 1, comprising support means having parallel axes for two coils carrying respectively the first and the second strip, a conveyor for moving an initial segment of the second strip from an initial position to a connection position in which the said segment covers a final segment of the first strip and an interpenetration connection device which comprises a base located on one side of the said segments in the recovery position mutual and a pressure organ located on the other side and capable of causing the interpenetration of bonding zones superimposed belonging to the said strip segments, characterized in that means for fixing the two strip segments relative to the base surface are associated exclusively with the base.
  • Figs. 1, 2 and 3 show the essential elements of the machine and illustrate the implementation of the process. These figures show a mandrel 1 for supporting a first coil 3 on which is wound a strip 8 and a mandrel 2 for supporting a second coil 4 on which is wound a strip 11. These mandrels are discs located at same level, with parallel axes and sufficient spacing so that, when the first coil 3 is about to run out, the second coil 4 can be mounted on the mandrel 2.
  • the reel support mandrels are associated with a supply device which can be arranged in different ways depending on whether the reels are put in place and prepared for unwinding by hand or in a mechanized manner. This device is not part of the invention and will not be described here.
  • a final segment 5 (fig. 2) of the strip 8 wound on the first reel and an initial segment 6 of the strip 11 carried by the second reel takes place in a connecting device generally designated by 7 and which will be described in more detail later.
  • the strip 8 is unwound from the first reel 3, passes over a roller 9 and is then led to a machine for manufacturing cigarettes.
  • the unwinding of this reel 3 is activated by means which are not shown, so as to create a reserve of paper 10 downstream of the connecting device 7. Then, it is possible to block the reel 3 to make the connection.
  • a last length of strip, which forms the final segment 5, is then partially in the connecting device and a cutter 29 is actuated so as to cut this final segment along a line located at a predetermined location.
  • a conveyor 12 to which the initial segment 6 of the paper strip 11 wound on the reel 4 has been fixed is moved from an initial position shown in FIG. 1 at a connection position shown in FIG. 2, so that the initial segment 6 of the strip 11 is placed opposite the final segment 5 of the strip 8 and is superimposed on it. Connection zones which will be defined later and which belong to these two segments are then exactly superimposed in the connecting device.
  • the segment 6 is then fixed relative to the base of the connecting device.
  • connection means are used so as to link the two final and initial segments by interpenetration, as shown diagrammatically in FIG. 3.
  • the strip portion 8 set aside provides the necessary power for the cigarette machine.
  • the new coil 4 can be rotated or more exactly released and a continuous strip moves in the direction of the manufacturing machine.
  • FIGs. 4 to 8 show different aspects of the connection device 7.
  • a vertical wall support 13 (fig. 7 and 8) carries a general console 14 itself supporting the essential elements of the connection device.
  • the console 14 carries a plate 19 and is arranged with a base fitted with three fixed nozzles 16, 17 and 18.
  • the plate 19 (see fig. 4, 5 and 6) located in the center and flush with the horizontal upper surface 14a of the console 14 is designed so as to cooperate with a punch 20 located above it and the operation of which will be described later.
  • the squeegee 16 is arranged in the base 14a in front of the support element 19. It comprises a horizontal collector 16a communicating by two rows of five conduits 16b with the surface 14a and a connector 21 which is connected by a tube 22 to a vacuum source.
  • the orifices of the conduits 16b open into the surface 14a in the form of two parallel rows spread over a width corresponding to the width L of the strips 8 and 11 carried by the mandrels 1 and 2.
  • the squeegees 17 and 18 have a constitution similar to that of the squeegee 16 and each comprise two rows of orifices 17b and 18b arranged side by side behind the support element 19, a slot 23 being arranged between these two squeegees.
  • nozzle 24 which comprises a cylindrical body fixed to the console 14.
  • This cylindrical body is provided with several rows of conduits 24b and comprises a central manifold 24a. The latter is connected by a connector 25 to a suction tube 26.
  • the nozzle 24 is placed at a certain distance behind the part of the base 14 which carries the nozzles 17 and 18.
  • a slot 27 whose function will be described below is provided between the squeegees 24 and 18.
  • the cylindrical body of the squeegee 24 is tangent to the horizontal plane of the surface 14a and in particular to the flat upper face of the support element 19.
  • the connecting device 7 comprises a roller tensioner 28, a cutter 29, and a punch 30.
