Definitions

  • the present invention relates to a packaging device, in particular for labels, comprising a fixed pathway on which labels are fed discontinuously and pushed in a continuous column, on their edges, by a pushing member. with discontinuous action, means for guiding the column of pushed labels, means for retaining labels for retaining the column of labels when the pushing member does not exert any action, a separation device comprising a member separator capable of penetrating between two labels of the column, at the stop of the pushing member, and means for packaging the packages separated by the separating member comprising a device for supplying a packaging material, a device for cutting this material and means for applying this material to the separate packages, as well as possibly a device for cutting the labels arranged between the pushing member and the device for s sparing.
  • the present invention also relates to a method of packaging, in particular of labels, comprising the discontinuous feeding of labels on their edge to a feed channel, the discontinuous pushing of these labels on this path with formation of a continuous column of labels, a possible cutting of the labels into a column then taking place, the separation of packets of labels from the column by the introduction, at each stop of the discontinuous push, of a separating member between two labels, supplying a packaging material, cutting this material and applying the cut material to the separate packages, so as to keep the labels of each package assembled.
  • a device is known as described in the preamble (utility model in the Federal Republic of Germany 1,835,773) in which the column of labels is pushed through an adhesive strip arranged perpendicular to the direction of advance packets of labels.
  • a welding instrument seals each strip after it has been wrapped around a bundle.
  • This device has the disadvantage that the packaging material used is an adhesive strip. This necessarily results in a transfer of the adhesive gum onto the edge of the labels and, during the next phase of treatment, namely the gluing of the labels to the container, bottle or other, the gluing palette causes several labels to be applied. that time. In the case of very large packages, for example 1000 labels, and although the tape is adhesive, it does not hold the labels sufficiently together. Finally, serious problems arise from the moment when the labels have a shape other than rectangular. Indeed, the labels can take partially to completely rounded, triangular shapes or in the crown sector and in this case the packaging strip no longer allows satisfactory packaging.
  • banding devices packets of labels in line are advanced towards a ribbon of hot-melt material of markedly width lower than that of the labels, arranged perpendicular to the direction of advancement of the label packs.
  • a welding instrument seals each tape after it is wrapped around a package.
  • This device has the disadvantage that it is only applicable for labels which have not had to pass through the punch, therefore of rectangular shape, and this for the same reasons as those indicated for the previous device.
  • a packaging device sold by the company Blumer Maschinenbau which comprises a device, in which the path on which the labels are fed is oriented in an inclined plane upwards, the labels being supplied in packs by example of 1000 with a cardboard interlayer before passing through the cookie cutter which provides the cut labels with a channel also facing upwards.
  • a device drives out the intermediate cartons from the column of labels by accommodating in their place a pallet which advances each packet of labels in buckets circulating on an endless chain.
  • the labels are assembled in a device which spreads a thread of adhesive material over the upper edges of the labels.
  • the disadvantage of this device lies in the fact that the labels are not well held together if there is not really transfer of the adhesive material between the labels and, in this case, there is a risk of tearing or d training of several labels at the same time when they are used in subsequent chains, for example during bottling.
  • the pushing member only allows the labels to pass through the cookie cutter and the device needs an independent label transport system for the rest of the operations.

  • the flanges 32 and 33 have during this ascent folded the cut edges of the packaging material against the front front 35 of the column 2 and the rear front of the separate package 9, the edges 43 and 44 of the flanges 32 and 33 used to fold the packaging material and to keep it trapped between the flange 32 or 33 and the front edge 35 of the column 1 or the rear edge of the separate package 9.
  • the control unit then causes the cylinders 16 and 22 to rise in order to raise the holding elements 14 and spacers 15. At this time, the column 2 is held in place between the retaining clips 5 and the flange 32 of the intermediate element 29 and the separate package 9 between the flange 33 and the rear flange of the intermediate element 29 'previously introduced on the path 1.
  • the control unit causes, from the signal given by a detector of the limit switch type that the jacks 16 and 22 are in the high position, restarting the thrust member 3 and the power supply.
  • the thrust of the thrust member 3 is transmitted not only to the label column 2, but also to the separate packages, via the intermediate element 29.
  • the control unit simultaneously causes the stop and the disengaging of the motor 100 which has just brought the mobile carriage 12 in the direction of the separation device 8, during the stopping of the thrust member, the return of the jack 95 to its flat position and therefore the raising of the hook 60 under the action of the spring 96, which allows the attachment of the mobile carriage to the rack 41 of the intermediate element 29 ', and the return of the jacks 27 and 27' to their initial position, which brings the spacer element 15 parallel to the holding element 14. Since under the thrust of the thrust member the intermediate element 29 'drives the movable carriage 12, the intermediate element 29 simultaneously exerts on the label column 2 upstream back pressure which is favorable to obtain a good cutting of cookie cutter labels.
  • the separate package surrounded by the packaging sheet then forming a kind of channel passes under the two flanges 112 which fold the packaging sheet over the upper face 71 of the separate package 9.
  • the control unit causes the cylinders 69 and 70 to be lowered towards the separate package 9 and allows the passage of electric current through the resistor 68, which causes the latter to heat and allows the edges of the hot-melt sheet folded over the top face of the package to be welded when the resistor is in contact with the latter.
  • the heating is interrupted after a predetermined time, but the bar 67 remains compressed against the package 9 until the thrust member 3 stops.
  • the control unit triggers the temporary opening of the valves 98 of the nozzles 80 and 81, which allows, by blowing compressed air on the upper part of the flaps, the folding of these respectively against the rear flange of the intermediate element 29 'applied against the front edge of the separate package 9 and the front flange of the intermediate element 29' applied against the rear front of the previously separated package 9 ', as well as the return of the cylinder 77 to the high position, which brings the lever arms 73 and 74 closer together.
  • a limit switch type detector signals the stop of the jack 77.
  • the free ends of the lever arms 73 and 74 are located opposite openings 78 provided in the flanges 32 and 33 of the intermediate element 29 '.
  • the control unit causes the displacement of each of the pushers of the double jacks 79 towards the pushing member and respective ment in reverse direction, and allows the passage of current ment in reverse direction, and allows the passage of electric current through the resistors 97.
  • the pushers then bear against the flanges of the intermediate element 29 'and the heating of the resistors 97 allows the welding of the flaps when they come into contact with the latter through the openings 78; this heating is automatically interrupted after a predetermined time.
  • the double jacks 79 however remain in the compression position until the operating cycle of the thrust member stops.
  • the control unit causes, in addition to the operations already described above, the return of the jacks 69 and 70 to the high position and therefore the raising of the bar 67, the return of the pushers of the double jacks 79, the return of the jack 77 in the low position and therefore the spacing of the lever arms 73 and 74, the passage of the jack 95 in the low position and therefore the lowering of the hook 60 against the return spring 96, as well as the clutch and the starting of the engine 100.
  • the movable carriage 12 attached to the intermediate element 29 accompanies the separate package during a complete operating cycle of the thrust member 3.
  • the motor 100 is disengaged and it is in fact the pushing member 3 which allows the carriage 12 to move forward. It is therefore necessary that the folding and welding phases be completed when the pushing member 3 stops.
  • the carriage 12 is unhooked and the motor 100 is engaged. And triggered so as to actuate the chain 61 in the direction of return of the carriage 12 to its initial position where it must be before the start of the next cycle of operation of the thrust member 3.
  • the intermediate element 29 ′ released from the mobile carriage 12, slides at a certain moment between the parallel branches 113 of the receiving member 82.
  • unit control causes the cylinder 84 to return to the low position, which causes the lowering of the intermediate element 29 ′.
  • the flanges of the latter slide down, freeing themselves from the welded flaps which cover them, the weld points sliding in turn in the openings 78 open upwards.
  • the intermediate element 29 ′ is immediately driven by the endless chain 101, which at this time is itself driven by a motor, not shown (see FIG. 1).
  • the chain 101 drives the intermediate element 29 'to a predetermined distance from the introduction member 28. At this time the aforementioned motor is stopped.
  • the control unit causes the jack 84 and consequently the receiving member 82 to go back up.
  • the closure devices of the packaging instead of being devices for welding hot-melt material, will then be devices for applying adhesive tapes.
  • the feeding of the pushing member can be an automatic feeding or a hand feeding.
  • a cookie cutter may or may not be provided.
  • the dimensions and shapes of the intermediate element can be modified according to the dimensions and shapes of the labels to be packaged, and the intermediate element can for example have two fixed flanges relative to the spacer.
