Definitions

  • the article receiving means is provided with a plurality of cells spaced at angular intervals around the axis of ro tation, and each adapted to receive one block of cigarettes to be wrapped in a sheet of wrapping material, which is introduced into the cell prior to the cigarettes being introduced therein.
  • Each cell is associated with a respective suction chamber defined between the outer wall of the cell and a perforate wall thereof.
  • Each suction chamber when connected to a source of vacuum pressure, serves to retain a sheet of wrapping material in contact with the perforate inner wall of the cell.
  • Each cell is so dimensioned that the width of the cell as measured by the distance separating two mutually parallel inner perforate wall portions thereof is substantially less than the extent of these perforate wall portions as measured in a direction extending generally radially of the axis of rotation.
  • the shaft is provided with a plurality of longitudinally extending passages each in communication with a suction chamber of a respective one of the cells.
  • the revolver is provided with valve means co-rotational with the shaft.
  • Each of the longitudinal passages is selectively connected to the source of vacuum pressure via the valve means when and only when the respective cell is located in a predetermined range of angular positions relative to the axis of rotation.
  • the present invention relates to a revolver for use as part of a packaging machine for wrapping block-like articles in packaging material.
  • Co-pending United Kingdom Pat. application No. 48186/72 discloses a packaging machine for wrapping block-like articles such as cigarette blocks in packaging material. for example of paper or viscose or cellulose film. and the present invention concerns an improvement in, or modification of, the arrangement shown in that co-pending patent application.
  • a revolver for use as part of a packaging machine for wrapping block-shaped articles in packaging material, the revolver comprising a shaft mounted on a support to be rotatable about the longitudinal axis of the shaft. article receiving means connected to the shaft to rotate therewith. cavity defining means provided by wall members of the article receiving means to define a plurality of cavities spaced at angular intervals about the axis and extending in a generally radial direction relative to the axis. perforate members in each cavity in spaced relationship with the wall members of the respective cavity to define cells, each bounded by the perforate members and each adapted to receive one such article.
  • each cell being greater in a direction radial of the axis than in a direction tangential at the cell to a circle passing through all of the cells.
  • the circle having its centre on the axis and being disposed in a plane perpendicular to the axis.
  • the revolver further comprises a plurality of longitudinally extending passages defined in the shaft, each longtudinal passage communicating with a respective one of the chambers. and valve means co-rotational with the shaft. the valve means selectively connecting each longitudinal passage to a source of vacuum pressure on the respective one of said chambers being located within a predetermined range of angular positions relative to the axis.
  • the entire revolver. and in particular the cells. are constructed of materials of low weight, for example light sheet metal. and the immediate mounting of the cells. which may take the form of holder members attached to a main body member in the form of a disc. are preferably also constructed with aperture provided for the purpose of reducing the total weight of the assembly required to rotate in operation of the packaging machine.
  • a plurality of intermediate strip members are provided between the outer wall members and inner perforate members of each of the cells, to give support to the inner perforate members relative to the outer wall members.
  • an eight-cell revolver may be expected to show fewer advantages than a four-cell revolver. for two reasons, Firstly, all the requisite operations can be carried out on each cigarette block in four cells, so that for efficient operation no more than four cells are absolutely necessary. Secondly. an eightcell revolver must. of necessity, be constructed with a larger size than a four-cell revolver. thereby giving a larger moment of inertial, with correspondingly increased power requirements for acceleraton and braking. In principle. any integral multiple of four cells may be provided on a revolver. but in practice a twelve'cell or sixteen-cell revolver. or an even larger one. is gener ally speaking too unwidely and cumbersome to operate efficiently.
  • FIG. I shows a sectional view of a revolver. taken in a plane perpendicular to the axis of rotation of the revolver;
  • FIG. 2 shows a sectional view in plane containing the axis of rotation of the revolver shown in FIG. 1. the part of the revolver mounting the cells and also the arrangement for the control of the reduced pressure supply to the chambers between the internal and external walls of the cells being shown;
  • FIGS. 3 to 6 show individual control plate members, and the control channels defined thereby. in sectional view in a plane perpendicular to the axis of rotation of the revolver shown in FIGS. I and 2;
  • FIG. 7 shows a sectional view. in a plane containing the axis of rotation of a second embodiment of the re volver.

  • FIG. 1 shows four cells 21/22. shown at a. b. c. and def the revolver. each cell being made up of a perforated inner wall 326 (the perforations being shown at 322), an outer wall 327 and a number of intermediate strip members 328 and end closure strip members 329 (FIG. 2 The outer and inner walls of each cell, together with the intermediate and end closure strip member, define a suction chamber 35] associated with the cell.
  • a U-shaped web 330 of packaging material In cell a of the revolver shown in FIG. I there is shown a U-shaped web 330 of packaging material.
  • Each cell is mounted on a holder 24/25, each holder being formed with a cavity therein to reduce the total weight of the revolver. and each holder being rigidly carried by a mounting plate 213, which is also provided with cavities therein to reduce the total weight.
  • Four longitudinal bores 301 a. b. c and d pass through the mounting plate 213 close to the axis of rotation, as shown in FIG. 1, and are connected to the respective cell suction chambers by radial bores 31] and further radial bores 321 in the holders 24/25.
  • 55/56 denotes a connecting shaft to be connected to a motor (not shown) to rotate the revolver as desired stepwise
  • 308 denotes a shaft coupling connecting the connecting shaft 55/56 to a revolver shaft 55a/S6u.
  • the latter shaft is journalled at ball bearings 305, 305a to be rotatable within and relatively to a support bearing member 58/59 which is stationary at all times during operation of the machine.
  • An end cap 306 is fitted at one end of the support bearing member 58/59, and two members 310 and 206 are fitted at the other end.
  • the parts indicated by numerals 206, 202, 204 and other parts of the revolver arc similar to the correspondingly numbered parts shown in the drawings of co-pending United Kingdom Pat. application No. 53141/72, which discloses in detail a folding arrangements which may be used with the presently described revolver.
  • the longitudinal bores 301 a, b, c and a extends towards the left (FIG. 2) through the shaft 55u/56a for differing lengths, so that bore 3100 is the longest, bore 301b the second longest, bores 3010 the next longest, and bore 301d the shortest.
  • Numeral 313 denotes a suction chamber within the mounting plate 213.
  • Bolts 215 threaded into the right-hand ends of the bores 301 are effective to seal these ends of the bores.
  • a series of consecutive control plate members, which may be integral with the shaft, defining arcuate peripheral control channels are provided to constitute the portion of the shaft 550/5611 just to the left of the ball bearing 305a.
  • each of these plate members is sealed against the adjacent one by an O-ring (one of which is shown at 323).
  • O-ring one of which is shown at 323
  • FIGS. 3 to 6 show respective ones of the plate members associated with the cells a, b, and d respectively.
  • each con trol plate member defines a peripheral control channel 302, each of the four control channels 302 subtending the same angle at the axis of rotation of the revolver, and the control plate member in each case having a portion 333 of radius substantially equal to the diameter of the bore passing longitudinally through the sup port bearing member 58/59, and bounding the two ends of the respective control channels 302.
  • the positions of the individual plate members shown at a, b, c and a in FIGS. 3 to 6, along the axis of rotation, are shown in FIG. 2.
  • Each control plate member is provided with a differ ent number of axial bore portions 301 (FIGS. 3 to 6), the contol plate member a having only one bore portion 301 therethrough adjacent its top region, the plate member b having two bore portions, adjacent its top and left-hand side. the plate member having three bore portions. adjacent its top, left-hand side and bottom, and the plate member d having four symmetrically positioned bore portions therethrough, in a square configurations as shown in FIG. 6.
  • Radial bores 11, b, c and d are provided in the support bearing member 58/59. for example in its bottom region as shown in the Figure, the upper ends of the radial bores communicating with the lower portions of the control plate members shown in FIGS. 3 to 6.
  • Pressure equalishing chambers 312 are provided below the radial bores a, b, c and d and communicate at their bottom ends with a connecting chamber 314 which in turn communicates with four individual further bores 315 which open at their lower ends into a vacuum line 332 connected to a vacuum connection nipple 318.
  • Reference numerals 316 and 317 denote a base support member and an adaptor projection respectively.
  • FIGS. 3 to 6 taken in conjunction with FIG. 2, shown that in the arrangement illustrated the suction chamber of cell a is connected to the connecting nipple 318 by the radial bores 321, the cavity 324/325, the chamber 313, the radial bore 3110, the longitudinally bore 3100 (including the portions thereof extending in a direction parallel to the axis through control plate members a, b, c and d shown in FIGS. 3 to 6), the pressure control channel 302 shown in FIG. 3, the radial bore a through the stationary support bearing member, the left-hand chamber 312, the chamber 314, the left-hand bore 315, and the passage 332.
  • the suction chamber of cell b is connected to the connecting nipple 318 by corresponding passages and bores, but in this case the con nection is made through control channel 302b shown in FIG. 4.
  • the connection is through the control channel 302:, but in the case of cell d there is no connection of the corresponding suction chamber of the cell with the connecting nipple 318, since the portion 333 (of full radius) of the control plate member shown in FIG. 6 blocks the corresponding radial bore leading to the corresponding bore through the support bearing member 58/59.
  • the perforated inner wall 326 is preferably provided with perforations all the way round, and may conveniently be made of sheet metal in the manner ofa sieve, as in the case of the outer wall 327 and the strip members 328 and 329.
  • the revolver is rotated stepwise, at a time, so that the various successive operations required to be carried out by the packaging machine may be carried out at successive stations of each cell.
  • Such operations are more fully described in co-pending U.K. Pat. applications Nos. 48I86/72 and 53l4I/72.
  • Vacuum applied at the connecting nipple 318 is effective in the suction chambers of cells a, b and c, as above described, but no vacuum is effective at cell d, to facilitate the relationshipslion of a cigarette block situated in a cell d by a pusher member acting in a direction parallel to the axis of rotation of the revolver.
  • each of the control plate members shown in FIGS. 3 to 6 executes a 90 rotation in the anti-clockwise sense, so that the full radius portion 333 of the control plate member of FIG. 5 blocks the downwardly open exit bore shown by the arrow 0 in FIG. 5, thereby blocking the connection between the connecting nipple 318 and the vacuum chamber of the righthand cell in FIG. I in the new position of the revolver.
  • the control plate member shown in FIG. 1 executes a 90 rotation in the anti-clockwise sense, so that the full radius portion 333 of the control plate member of FIG. 5 blocks the downwardly open exit bore shown by the arrow 0 in FIG. 5, thereby blocking the connection between the connecting nipple 318 and the vacuum chamber of the righthand cell in FIG. I in the new position of the revolver.
  • FIGS. 7 and 8 there is shown a second embodiment, in which a vacuum connecting nipple 357 is provided on a boss 351 supported by an arm 355 to be stationary at all times during operation of the machine, the boss 351 containing a segment-shaped chamber 353 with a valve member 354 (FIG. 8).
  • a sealing ring 352 seals the boss 351 against the revolver shaft, shown at 55a/56a.
  • FIGS. 7 and 8 the other reference numerals corresponds to those shown in FIGS. 1 to 6, and indicate similar components.
  • the shaft 55a/56a is provided with a cavity 356 for the purpose of the reduction of weight of the assembly to be rotated, and otherwise this second embodiment is of generally similar configuration to that shown in FIGS. 1 to 6.
  • boss 351 is situated in front of the holders which mount the cells, while in the case of the first embodiment simpler removal, when desired, of the cells and holders is possible, because there is no component corresponding to the boss 351.
  • the bores 301 a, b, c and d are very much shorter, and the segment-shaped chamber 353 with the valve member 354 provides a particularly simple and convenient arrangement for ensuring that the desired one of the four bores 310 a, b, c and d is at each particular step in the rotational motion ofthe revolver shaft isolated from the source of reduced pressure connected at 357.
  • the connecting shaft 55/56 shown at the left in FIG. 2 is preferably tubular, again for the purpose of weight reduction. This shaft may conveniently be made oflight metal.
  • the first embodiment shows the advantages of easy removal of the cells and holders from the remainder of the rotary assembly of the revolver, and of course good accessibility. This may be of great importance in the case of the revolvers II and III of the arrangement disclosed in co-pending U.K. Pat. application 48186/72.
  • the spacing at the circumference between the successive cells is conveniently about 200 millimetres from the edge of one cell to the adjacent edge of the next cell.
  • the diameter of the revolver is in such a case conveniently 320 millimetres.
  • a revolver with six cells is a possible construction, with the same spacing between cells at the circumference of the mounting plate 213, but in this case the diameter would be about 482 millimetres, giving rise to a revolver with a much larger moment of inertial, which may therefore be expected to operate in less efficient manner.
  • a six-cell revolver if two mutually opposite cells stand vertically, as shown in FIG. 1 at cells a and c with a four-cell revolver, then no cells stand horizontally as they do with a four-cell revolver. This is generally inconvenient for the feeding-in ofa cigarette block, since the cell receiving the block is obliquely inclined.
