Definitions

  • the present invention relates to a system for regulating the feed of articles to a wrapping machine, in which this wrapping machine includes means for advancing longitudinally a wrapping strip which bears a series of marks spaced longitudinally from each other, and first sensor means arranged to detect the passage of the said marks to provide signals indicative of the positions of the strip at predetermined instants, the said system including:
  • the object of the present invention is to provide a system for regulating the feed of articles to a wrapping machine which is simpler and more practical than the known solutions described above.
  • the invention provides a regulating system the main characteristic of which lies in the fact that the said second sensor means are actuated by output signals from the said first sensor means, whereby the output signals from the second sensor means are indicative of any devration of each article from the correct position in phase with the wrapping strip of the wrapping machine.
  • the output signals from the first sensor means containing the "information" from the wrapping strip, are used directly to "phase” the articles carried by the conveyor means with respect to the wrapping strip, wherein it differs from the known systems in which the "phasing" of the articles relative to the wrapping strip is achieved by “phasing" both the articles and the wrapping strip relative to the bladed conveyor.
  • the system according to the invention thus allows the elimination of the need for this bladed conveyor. Furthermore, since the "phasing" of the articles relative to the wrapping strip is achieved by using the "information" from the wrapping strip directly, it is no longer necessary to provide for varying the speed of the wrapping strip. This avoids the need to use an adjustable mechanical transmission for driving the wrapping strip, wherein it again differs from known devices.
  • the said second sensor means are also arranged to indicate the degree and direction of any deviation of each article from the correct position in phase with the wrapping strip, and the said control means are arranged to correct the speed of the conveyor means to an extent proportional to the degree of deviation detected.
  • reference numeral 1 generally indicates a wrapping machine using a paper strip 2 which unrolls from a feed roller 3 to form the wrappers for the articles.
  • the paper tube 5 is supported by two longitudinal supports 7 having opposed L-shaped cross-sections which together define a longitudinal slot 8 through which the fin 6 projects.
  • the wrapping machine is provided with a series of pairs of wheels 9 driven by an electric motor (not illustrated), which engage the two sides of the longitudinal fin 6 to join the longitudinal edges 4 of the paper strip together and draw the paper tube 5 in its longitudinal direction.
  • a belt conveyor 10 which feeds a series of articles 11 to be wrapped, which are spaced longitudinally from each other, into the paper tube 5.
  • the speed of the conveyor 10 is substantially the same as that of the movement of the paper tube 5.
  • the articles 11 are deposited on the lower part of the-internal surface of the paper tube 5 (see Figure 3) and are drawn by the latter towards two contra-rotating jaws 12 (see Figure 1) of the type known per se which join together the walls of the paper tube in the zone immediately between one article and the next and separate the successive articles from each other.
  • Figures 5 and 6 illustrate the wrapped article obtained.
  • reference numeral 14 generally indicates the wrapper of the article
  • reference numeral 15 indicates each of the two transverse fins obtained as a result of the joining and cutting effected by the jaws 13.
  • Reference numeral 16 shows the lower longitudinal fin corresponding to the section of the fin 6 which is separated from the paper tube by the jaws 13. The article is then sold in the condition illustrated in Figure 6, that is, with the fin 16 folded so as to be parallel and adjacent the lower surface of the package.
  • a conveyor device schematically shown as 17, is disposed downstream of the jaws 13 and receives the wrapped articles from these jaws, conveying them to the output of the wrapping machine.
  • the wrapper 14 of each article bears specific graphics 18 (for example, writing or a design) which must be "centered" relative to the article itself. Consequently, the articles 11 must be fed into the paper tube 5 which bears the succession of graphics 18, in a predetermined phase relationship.
  • the use of the said bladed conveyor is avoided, as is also the use of the said adjustable mechanical transmission between the wheels 9 and the motor which drives them. Indeed, the translational speed of the paper tube 5 never varies.
  • the paper strip 2 is still provided with a series of centering marks.
  • at least one of the two longitudinal edges 4 (see Figure 4) -of the paper strip 2 bears a series of marks 19 of a material or colour which is different from that of the remaining part of the strip, which gives rise to the same number of centering marks 21 on the longitudinal fin 6 of the paper tube.
  • the wrapping machine further includes a sensor device 22 arranged to detect the passage of the marks 21.
  • the sensor device 22 is constituted by a photoelectric cell cooperating with a device 23 arranged to direct light onto it.
  • conveyor means 24 Upstream of the forming end of the paper tube 5 are provided conveyor means 24 (see Figures 1 and 2) which, in the example illustrated, comprise the above- mentioned belt conveyor 10 and, upstream thereof, an accumulation belt conveyor 25 on which the articles 11 intended to be fed to the wrapping machine are accumulated.
  • the belt conveyor 10 moves at a speed greater than that of the belt conveyor 25, so as to cause the spacing of the articles 11 from each other, and has a length such that there is never more than one article present thereon.
  • the sensor device 22 is connected to control means 26 which are also connected to sensor means 27 associated with the belt conveyor 10.
  • the control means 26 are finally connected to a motor 40 (indicated schematically in Figure 2) which drives the movement of the belt conveyor 10.
  • the control means 26 are arranged to actuate the sensor means 27 when the sensor device 22 detects the passage of a centering mark 21.
  • actuation of the sensor means is intended to refer both to the case of proper actuation of these sensor means and to the case in which the sensor means are in fact always active, the "actuation” mentioned above consisting of comparing the output signal from the sensor means with a predetermined threshold signal).
  • control means 26 act on the motor 40 to vary the speed of the belt conveyor 10 so as to correct and take up this deviation.
  • the sensor means 27 are constituted by four photoelectric cells 28, 29, 30, 31 in longitudinal alignment with each other.
  • the sensor device 22 detects the passage of a centering mark 21, that is, at the moment of the activation of the photoelectric cells 28 to 31, an article 11 should, to be correctly in phase with the paper tube 5, have its front end located between the cell 29 and the cell 30.
  • the cells 28, 29 should be obscured while the cells 30, 31 should be clear.
  • control means 26 are arranged to correct the speed of the motor 40 proportionally to the degree of deviation detected by the sensor means 27.
  • the sensor means 27 may be constituted by any number of photocells, the precision of the indication of the degree of deviation from the correct position of each article being greater the greater this number.
