Definitions

  • a machine for labelling bottles or containers comprises a label feeding unit for feeding labels to a labelling channel of the machine and a container feeding unit for feeding containers to the channel, the containers being turned during their movement along the channel so that they can be applied to the containers and wrapped fully around the latter during movement of the containers along the channel.
  • the present invention relates to a machine for labelling bottles or containers of various shapes and of any given cross-section, which may be curvilinear or polygonal, which machine is adapted to position a label and apply it in an even manner, so that it overlaps itself and surrounds the whole of the periphery of the bottle or container.
  • a fullwrap labelling machine for labelling containers comprising a label-feeding unit which is phased to lead a container-feeding unit to a certain extent, so that when a container is engaged in a labelling channel of the machine, a label fed by the label-feeding unit already precedes the container by a relatively great length on one side of the channel, means being provided for folding back the portion of the label which is advanced relatively to the container, around the part of the container which is directed forwardly in relation to the movement of the container,
  • the portion of the label preceding the container on the said one side of the channel is of a length corresponding substantially to a half the total length of the label, so that when the label is turned back over the said forwardly directed part of the container, the label is folded back approximately at its middle.
  • this feature resides in the fact that in bending the label back at its middle portion, and thus effect wrapping thereof, in a single movement, over half the length of the label, even positioning is ensured since after having applied the label in a single movement to the container, and over a largewportion of the surface, thereof, slipping is avoided or minimised; much larger slipping occurs when contact takes place initially along a generatrix of the surface of the container, with the contact area progressively increasing little by little.
  • a further advantage of the machine according to the invention resides in the fact that if the periphery of the container is deformed, folding back the label at its middle portion counterbalances and reduces the offsetting effect of the deformation, whereas the offsetting effect would be magnified if wrapping were to be commenced at the leading edge of the label and continued progressively to the trailing edge.
  • FIG. 1 is a diagrammatic plan view of one form of machine according to the invention.
  • FIG. 2 is a corresponding view showing a part of the modified form of machine.
  • a label box is provided at 1, transfer rollers at 2 and 3, a glue tank at 4, into which a glueing roller 5 extends, a further transfer roller at 6, and at 7, a label-feed roller at the entrance to a channel 8 for conveying the containers 9.
  • the containers are passed into the labelling channel from the channel 8 in the direction from left to right by means of an endless screw 10*.
  • At 11, 12, 13, 14, 15, 16, 17, 18, 19 and 20 are indicated the various special positions of the container along the length of the labelling channel.
  • the container can be of any desired shape: square, rectangular, oval or even cylindrical.
  • the roll 7 In addition to feeding the labels, the roll 7 also drives a set of belts 21, arranged vertically one above the other, which transport the containers along by frictional engagement with the sides thereof, together with the labels, over a certain length of the channel, the speed of the travel of the belts being equal to the speed of travel of a horizontal band 21a which supports the bottoms of the containers in the channel 8.
  • the belts are guided by various rollers such as 22 and 23, and also by further rollers 24, 25 and 26 which change the direction of the belts.
  • smoothing stations which may be constituted by brushes for instance, and at 30 and 31 there. are check rollers interposed in the path of the containers,
  • slide rails which guide the containers, these rails being either opposite the conveyor belts or opposite the smoothing stations.
  • Upper guide means for the containers are also provided above and parallel with the slide rails 35, 36 and 37 (not shown in the drawing) which bear on the upper faces of the containers to hold them, under a certain pressure, on the conveyor band of the channel 8.
  • the arrangement is, however, such that these means for applying pressure from above are not present opposite the check rollers 30 and 31, so that at these positions, the upper faces of the containers are unobstructed and the containers can pivot about their own axis, just to the right of the check rollers 30 and 31.
  • a label which has previously emerged from the magazine is gummed, in the usual way, and passes to the roll 7 which contains suction orifices distributed both along its generatrices and around its entire circumference.
  • the label is fed in advance of the container, so that a free length 38 of label precedes the container 12, this length corresponding substantially to the length which is required to cover the faces 12a and 12b of the container 12'.
  • the label is held in position by the suction orifices in the roll 7, which act on it progressively from its leading end to its trailing end, and by the pressure of the face 120 against the belts 21, and it thus remains in a particular vertical position, while itself maintaining a precisely horizontal direction.
  • the label is blown by the air jet system 32 so that it is turned or folded and flattened onto the front face of the container.
  • the label is no longer in contact with the roller 7, but it continues to be held in position by the gum that has been applied to the face 12c.
  • the overhanging part 38a which is not yet gummed, then passes in front of the brush 27 opposite the conveyor belts 21, so that on leaving the brush or smoothing station 27, the container 14 will have the label gummed to three faces thereof in a single operation.
  • the container then pivots twice about its own axis, firstly at 15, when it encounters the check roller 30, secondly at 18, when it encounters the check roller 31.
  • the course of the conveyor belts 21 is arranged to have a particular configuration opposite the said check rollers, to permit the containers to pivot.
  • the container reaches the position 16 which enables the smoothing brush 28 to apply the label to the fourth face of the container.
  • the portion of the label which precedes the container upon leaving the roller 7 is substantially equal to half the length of the label, so that at the moment when the air jet system 32 is brought into action, the label is turned back or folded at approximately its middle portion.
  • the function of the pressure applied by the air jet system 32 is simply to bend and turn back the label, and it is insuificient for applying the label to the faces of the container which are to be covered. Only the smoothing stations can apply suflicient pressure to deal with the complete application of the label to the container. It is important to point out that in these conditions the air jet system acts upon the leading portion of the label without the container pivoting about itself, rotation only occurring later when the first smoothing operation has been carried out.
  • the conveyor belts 39 are made of spongy material and the corners of the containers can be pressed gently into them when the containers pivot about their own axes in positions such as '40, 41, 42, and 43.
  • the pivoting is controlled by retractable non-driven rollers 44, 45, 46 and 47, mounted at the ends of articulated levers 48, 49, 50 and 51 which are biassed by resilient means such as springs 52.
  • the rollers 44, 45, 46 and 47 perform the same function as the check rollers 30 and 31 of FIG. 1, but they also constitute smoothing means.
  • the container occupies the position indicated at 53, wherein one of its faces is substantially horizontal and tangential to the surface of the roller 45.
  • the brushes or non-driven smoothing rollers used in the case of containers having flat faces could be replaced by guides made of foam rubber or some other spongy material, when used in the case of containers of circular section, so as to cause the containers to rotate about their own axes, due to the braking action applied circumferentially of the rollers.
  • portion 38a of the label that stands proud of the front of the container must be of a length such that the brush 27 at the first smoothing station can apply it to cover completely the corresponding face 12b of the container as it arrives at the position 13 and before it proceeds to position 14 after the operation of applying the portion 38a has been completed.
  • auxiliary belts would of course have to be interrupted or diverted to the right of the station at which the container rotates about its vertical axis.
  • an air jet system 32 has been indicated as being the means for turning back the label onto the front part of the container, other means could also be used.
  • a brush employing a reciprocating movement could be used, or a pair of pincers, or other like means.
  • a full-wrap labelling machine for labelling containers comprising a conveyor channel for containers to be labelled, a container-feeding unit for feeding containers to the channel and a label-feeding unit for feeding labels of elongated form at one side of the channel, said labelfeeding unit including means to feed a label for each container conveyed in said channel, to be engaged with and wrapped around said container, characterised by the fact that said container-feeding and label-feeding units include means to move a container in one direction in said channel and to feed a label lengthwise in a path parallel with and alongside a container and at the same speed thereof and means to initially tangentially apply only a trailing portion of a label to the adjacent side of each container while moving in said channel and to position the remaining portion of the length of each label thus initially applied ahead of the corresponding container in said channel, and by the fact that said machine further comprises means to deflect said remaining portion of each label laterally of said channel ahead of said containers, first label-engaging means to engage a portion of said remaining portion of each said label
