Definitions

  • the cigarette industry uses paper strips to form the paper cylinder containing the tobacco; these strips of paper are supplied in wafers, consisting of a large number of turns wound successively on themselves in order to constitute a ribbon of paper of great length.
  • the paper which must surround the filter of cigarettes paper which is of a different type than that directly surrounding the tobacco of the cigarette.
  • the methods and devices according to the prior art are no longer suitable, given the particular mechanical characteristics of this type of paper.
  • the paper surrounding the filter of a cigarette has a structure and a texture different from that of cigarette paper, with glue as binder, which increases its roughness and decreases its porosity;
  • the paper ribbon coming to surround the tobacco cylinder is then placed longitudinally with respect to said tobacco cylinder, which means that the width of the paper ribbon is generally quite small, of the order of 25 mm, it is not the same for the paper tape surrounding the filter of cigarettes where said paper tape is wound transversely relative to the filter; the machine generally having two filters arranged end to end, and the filters being able to be relatively long, one can have ribbons of paper clearly wider than previously, being able to go up to 70 mm.
  • the object of the invention is to propose a method and a device making it possible first of all to open a full wafer, then to assemble the outer end of the paper strip coming from this full wafer to the 'inner end of a nearly empty cake, this method and this device being applicable to paper ribbons to surround cigarette filters.
  • An advantage of the device according to the invention is that the wafer opening device and that of assembly are combined on the same machine, thereby reducing the space required for these devices; on the other hand, given the particular characteristics of the assembly of the two ribbons, assembly which is particularly resistant to the traction of one ribbon on the other, this method and this device can be used for the assembly of ribbons of other kinds. as paper ribbons, ribbons made of thin aluminum sheets for example. The characteristics of the process and of the device do not preclude the assembly of cigarette paper ribbons.
  • the machine cutting the paper tape is shown schematically in Figure 1 by its frame 1; it comprises in particular a robotic arm 10, provided with an arm head 11 capable of carrying out the movements of the wafers 2, 2a, 2b, as well as those of the roller support 14, as described below.
  • This robotic arm 10, as well as its head 11 are not part of the invention and can be of any type known in the art, only some of the operations performed by said arm being new.
  • a paper wafer 2, driven in rotation by a first axis of rotation 12, unwinds its paper tape 20 towards the machine responsible for placing it around the tobacco, respectively around the cigarette filter, this machine not being shown on the figure.
  • a second wafer 2a was removed by the robotic arm from a storage position where we can distinguish a third wafer 2b on standby, and was brought and fixed on a second axis of rotation 13.
  • the wafers 2a and 2b are full and their outer coil is possibly covered with a strong paper protective strip.
  • the process of opening the full wafer 2a is implemented, firstly by making bring, by the robotic arm 10, the roller support 14 near the wafer 2a, so that the gripping cylinder 3 comes tangentially into contact with the outer circumference of the wafer 2a.
  • FIG. 2A The detail of the following steps in the process of opening the solid wafer 2a is shown in FIG. 2.
  • the gripping cylinder 3 has been brought into contact with the solid wafer 2a, and has been pivoted so that when 'it is open, as shown in the figure, it is ready to receive the strands of the outer turns.
  • the detail of the opening and closing mechanism of the gripping cylinder 3 will be explained later.
  • a first cutting device 4, fixed to the support 14 and comprising a cutting blade 40 is actuated by a piston device 41, to be brought against the solid wafer 2a so that the blade 40 cuts the possible protective strip of strong paper surrounding the wafer as well as some of the outer turns of said wafer, by a transverse movement of said blade.
  • FIG. 2B where a blowing device 5 has been brought directly near the cut made previously; this blowing device 5 is supplied by a source of pressurized air not shown and in particular comprises a plurality of nozzles 50, 51, 52, gradually oriented, which are actuated sequentially.
  • the first nozzle 50 which is directed against the cut made on the wafer 2a, is actuated first and lifts the cut ends 21, the second nozzle 51, blowing in a direction more recessed than the first, detaches the cut ends 21 and begins to bend them in the direction of the opening 30 of the gripping cylinder 3, while the third nozzle 52, directed still further back than the previous one, is now actuated to introduce the cut ends 21 inside the opening 30.
  • the blowing device 5 has been described with three nozzles 50, 51 and 52; it is obvious that it could have a different number of nozzles, or even have only one, the device then being pivoted at a certain angle around its axis in order to lift, detach, bend and bring the cut turns 21 inside the opening 30 of the gripping cylinder 3.
  • the gripping cylinder 3 is then closed, as shown in FIG. 2C, the movable part 31 of said cylinder pinching the cut ends 21 against the fixed part 32 of said cylinder .
  • Figure 2D shows that the gripping cylinder 3 has been rotated, driving the cut turns 21 and therefore the full wafer 2a; this rotation lasts long enough to wind all the outer turns cut around the gripping cylinder 3, as well as a certain length of paper tape from the wafer 2a.
  • FIG. 3A representing a perspective view of the active portion of the gripping cylinder in half-open, respectively semi-closed position
  • Figure 3B is a partial sectional view of the same device.
  • the gripping cylinder 3 consists of two main parts: a movable part 31 and a fixed part 32.
  • the active portion of the fixed part 32 consists of a hollow cylindrical tubular element, in which an opening 30 corresponding to a sector portion of said tubular element of 60 ° has been removed, defining the two faces 30a and 30b.
  • the fixed part 32 has the appearance d '' a sort of cylindrical comb, consisting of teeth 34 separated by notches 33.
  • the movable part 31 consists of a portion of cylinder sector 35 of 60 °, whose outside diameter corresponds to the inside diameter of the cylindrical tubular element of the fixed part 32; this portion of cylinder sector 35 is surmounted by a number of teeth 36, each of them corresponding in terms of location and dimensions to a notch 33 of the fixed part.
  • the outer diameter of the cylinder portion defined by the outer surface of the teeth 36 corresponds to the outer diameter of the cylinder defined by the fixed part 32.
  • the cylinder sector portion 35 of the movable part 31 is extended by a cylindrical shaft 37 pivoting at the interior of a cylindrical cavity 38 located in extension of the active portion of the fixed part 32; thus, by actuating in rotation in one direction or the other the cylindrical shaft 37, the movable part 31 which is fixed to it is pivoted, and consequently the teeth 36 of the movable part 31 are moved in the notches 33 of the fixed part 32, this movement taking place between two extreme positions, the first being the open position where the ends 36a of the teeth 36 abut against the bottoms 33a of the notches 33, the ends 36b of the teeth 36 then being aligned on the face 30b corresponding to the ends of the teeth 34 of the fixed part 32, which defines the opening 30 of the gripping cylinder, while the second extreme position is that where the teeth 36 have pivoted in the notches 33, until the ends 36b of said teeth are
  • the gripping cylinder 3 can open and close, due to the relative pivoting movement of the movable part 31 relative to the fixed part 32, the outer surface of said gripping cylinder remaining substantially cylindrical, subject the opening 30 in the open position as well as the notches 33 as well as those arranged between the teeth 36 of the movable part 31, the outside diameter of said cylindrical surface remaining constant for each position of the movable part 31 relative to the fixed part 32.
  • Figures 3A and 3B show a gripping cylinder 3, the fixed part 32 and the movable part 31 each have eight teeth; it is obvious that the cylinder according to the invention can include any number of teeth, this number being mainly determined by the width of the paper tape to be grasped; similarly the angle of opening and closing of the cylinder has been mentioned as being 60 °, any other angle giving a sufficient opening of the cylinder 30 can be adopted.
  • the head 11 of the robotic arm 10 will grip the support 14 and bring it to the low position, shown in dashed lines.
  • the gripping cylinder 3 carries with it the first turn of paper 22 coming from the wafer 2a, and lays it parallel and at a short distance from the paper tape 20 still unwinding from the almost empty wafer 2.
  • the rotational speeds of the cylinder 3, as well as of the wafer 2a are adjusted so that the ribbon 22 remains tensioned and is unwound at the same speed as the paper ribbon 20 for unwinding the wafer 2.
  • a pneumatic device symbolized by 6, then operates successively: a second cutting device 60, cutting the ribbon 20 unwinding from the almost empty wafer 2, slightly upstream from where the junction between the two ribbons 20 and 22 will be made, brings the two pressure rollers 70 and 71 closer together so that they make the connection between the two paper ribbons 20 and 22, move these two rollers away again when a certain length of the two ribbons 20 and 22 has been joined and finally actuates a third cutting device 61 in order to cut the end of r uban 22 still attached to the gripping cylinder 3.
  • the end of the paper tape 20 is now connected to the end of the tape 22 and it is the wafer 2a which then feeds the machine placed downstream and responsible for placing said tape around of the tobacco cylinder, respectively around the cigarette filter.
  • the succession of operations, described above, controlled by the pneumatic device 6, is carried out in a very short period of time so that the length of the ribbon where the ribbons 20 and 22 are superimposed is as short as possible.
  • the robotic arm 10 returns the support 14 to the high position, the gripping cylinder 3 opens again, which frees the free ends 21 and allows a conventional elimination device, not shown, to remove the layers of paper wrapped around the input cylinder 3. Then, the robotic arm 10 grasps the rest of the wafer 2 and eliminates it. When the wafer 2a has unwound a certain length of paper tape and has thus reached a given diameter, the robotic arm 10 will move it in order to bring it to the first axis 12 where it will continue to unwind, until it is almost empty and a new cycle of operations is ordered.
  • FIG. 4 shows the detail of the construction of the pressure roller device 7, FIG. 4A showing the two rollers 70 and 71 in perspective, arranged face-to-face, while FIG. 4B is a representation on an enlarged scale showing the interpenetration of rollers 70 and 71 between them.
  • the first pressure roller 70 is composed of a cylinder on which a plurality of cylindrical crowns 72 are arranged side by side, each of these crowns being spaced from the next by a certain spacing. Each of these crowns comprises a plurality of teeth 73, of generally triangular shape.
  • each tooth has the rotation of the roller 70 first of all the longest of the sides, according to a relatively slight slope, then the shortest of the sides according to a steeper slope .
  • the second pressure roller 71 also composed of a cylinder in which a plurality of cylindrical grooves 74 are hollow side by side, each of said grooves coming in front of a crown 72 furnished with teeth 73 of the first pressure roller 70.
  • FIG. 5 there is a representation according to two views of the assembly of the two ribbons 20 and 22.
  • FIG. 5A is a plan view of the assembly, the ribbon 22 cut at its end 22a being superimposed on the ribbon 20 cut at its end 20a. These two ends of ribbons 20a and 22a are inclined since the cut was made while the two ribbons 20 and 22 were in motion.
  • the central part of the superimposed part consists of a plurality of notches 23, arranged in a number of columns equivalent to the number of crowns 72 supporting the triangular teeth 73 of the roller 70, and according to a certain number of lines which is a function of the duration of application of the rollers 70 and 71 against each other.
  • FIG. 5B which is a section of the previous figure along a line B-B shows that the two paper ribbons 20 and 22 have been perforated and that each notch consists of two folded paper tabs; this type of assembly according to the invention, which essentially differs from the state of the art where there is simply an embossing of two superimposed tapes, without perforation of said tapes, is possible thanks to the particular conformation of the two pressure rollers 70 and 71 as well as teeth 73, according to the invention. Note in FIG. 5B, that a longitudinal pull from one ribbon to the other cannot detach them, but on the contrary makes them interpenetrate even more. FIG.
  • 5A represents the notches 23 arranged in a number of rectilinear lines; this arrangement comes from the fact that the teeth 73 on each ring 72 are aligned with one another, it is quite possible to provide a shift of the teeth between each ring, so as to have, for example, a staggered arrangement of the notches 23.
  • the method and the device according to the invention it is possible, on a single machine, to present a full wafer, to open it, to take the strip of closure paper as well as some outer turns of said full wafer, to connect the outer end of the strip of paper coming from the full wafer at the inner end of a nearly empty wafer and eliminating said almost empty reel, without interrupting the paper supply to the machine placed downstream.
  • the method and the device according to the invention have been specially developed for the connection of two strips of paper which must come to surround cigarette filters; given the characteristics and solidity of the junction where the two strips of paper are interpenetrated until the perforation, this type of connection can be used for the connection of other types of strips, whether it is strips of paper of a other composition or even strips made of thin sheets of aluminum, and this for strips of any width.
