Definitions

  • the present invention relates to a labelling machine for protruding skin packaging, an assembly comprising a labelling machine and a protruding skin packaging and a method of labelling protruding skin packaging.
  • Protruding skin packaging is frequently used for packages containing irregular sized and shaped items.
  • protruding skin packaging is used for consumer packaging containing meat, fish etc. This packaging may be used for joints of meat which are sold in the refrigerated sections of supermarkets. Due to the nature of the product, the size, shape and weight of these products varies and, accordingly, the size and shape of the upper surface of the packaging will likewise vary.
  • Protruding skin packaging maintains the product in a vacuumed atmosphere and such protruding skin packaging may increase the shelf life of the product.
  • protruding skin packaging uses relatively small tray portions which decreases the material required and subsequently decreases the waste material. Accordingly, protruding skin packaging is currently very popular.
  • the unpredictably shaped and positioned upper surface creates a problem when applying labels to the upper surface of the packaging.
  • These labels generally need to display individual information concerning the weight, cost etc. of the product.
  • Some packaging may comprise an extended planar section offset from the actual product onto which the individual label can easily be applied. This increases the packaging material and also increases the dimensions of the product which may therefore increase the storage, transportation and display required for these products.
  • Linerless labels include adhesive on one surface to enable the labels to be urged and hence adhered to the surface of the product.
  • a labelling machine may include fixed applicator surface to direct the label onto the upper surface of the packaging. Such labelling machines may be very effective when used with packaging of equal predictable sizes as they pass along a conveyor belt underneath the fixed applicator surfaces.
  • Skin packaging generally comprises a tray having a flange around the periphery and has a flexible film which locates over the product ion the tray and the film is vacuumed sealed to the tray to contain the product in the packaging.
  • Skin packaging may be classified as normal skin packaging in which the upper film surface locates below the flange, protruding skin packaging in which the upper film surface locates slightly above the height of the flange or super-protruding skin packaging in which the upper film surface locates high above the upper film surface.
  • Labelling machines having fixed applicator surfaces may be adequate when used with a protruding skin package which only protrudes by a relatively small amount since this can be accommodated due to the flexibility of the label.
  • such fixed applicator surfaces cannot be used with both protruding skin packaging and also super-protruding skin packaging since the fixed applicator surfaces are not able to accommodate the range of height of a super-protruding skin packaging as well as a normal protruding skin packaging.
  • Different labelling machines may therefore be provided to cope with different levels of protruding products.
  • a first labelling machine may be used for protrusions in a first range and a second labelling machine may be used for protrusions within a second range.
  • the fixed applicator surfaces for the label generally result in the label not being taut across the lateral extent of the packaging and the label may tend to bulge slightly outwardly. Accordingly, such sleeve labels may not provide a neat appearance and the information displayed may be obstructed or not clear.
  • a labelling machine for a protruding skin packaging comprising:
  • label feed means to deliver a label to label applicator means
  • label applicator means for urging the label on to the packaging
  • first lateral edge feed means and the second lateral edge feed means extend in a downstream direction beyond the central feed means in order for the first lateral edge feed means and the second lateral edge feed means to drive the label following the removal of the drive from the central feed means.
  • the label is arranged to move in a feed direction through the labelling machine from an upstream position to a downstream position.
  • the packaging is supported on a conveyor surface which moves from an upstream position to a downstream position wherein the conveying direction is the same as the feed direction.
  • the first lateral edge feed means and the second lateral edge feed means extend in a downstream direction beyond the central feed means in order for the first lateral edge feed means and the second lateral edge feed means to solely drive the label following the removal of the drive from the central feed means.

  • the labelling machine 10 generally comprises a conveyor system for conveying packaging 20 through the labelling machine 10. As is conventional, the conveying system is arranged to move a line of packagings 20 through the labelling machine 10 in a continuous manner. The labelling machine 10 also provides a label feed system for feeding labels 1 1 through the labelling machine 10 in order to be adhered to the packaging 20. Finally, the labelling machine 10 comprises an applicator system for applying the labels 1 1 to the packaging 20.
  • the labelling machine 10 may be located adjacent to, and downstream from, a weighing station. At the weighing station, each individual packaging 20 may be weighed such that an individual label 1 1 may be prepared and printed prior to being fed to the label applicator system of the labelling machine 10. This enables specific information for the product 21 to be displayed, for example the weight, cooking time etc. which may vary due to the actual weight of the product 21 .
  • the labelling machine 10 is for use with protruding skin packaging 20. Furthermore, the labelling machine 10, and specifically, the label feed system and the label applicators 12, 14, 16, may be used with either normal protruding skin packaging or super-protruding skin packaging.
  • Such packaging 20 comprises a tray 22 or base with a relatively low wall 24 defined around the perimeter such that the product 21 protrudes above the height of the wall 24.
  • the packaging 20 then also provides an upper skin 26 in the form of a (transparent) film which is secured (sealed) to the tray 22 and extends over the upper surface of the product 21 such that the product 21 is enveloped by the skin 28.
  • the packaging 20 provides a flange 28 which extends around the complete upper periphery of the wall 24 and extends outwardly therefrom. This flange 28 thereby provides the lateral (and front and rear) edges to the packaging 20.

Accordingly, the edge applicators 14, 16 provide dynamic applicator surfaces and also the edge applicators 14, 16 themselves move with respect to the conveyor surface to force and/or help wrap the label 1 1 around the packaging 20. The edge applicators 14, 16 drive and urge the labels 1 1 forwardly as they are being applied. The labels 1 1 are initially adhered along the central adhesive strip 40. Following this initial adherence, the labels 1 1 will be moved (dragged/pulled) forwards as the packaging 20 moves on the conveyor surface.

Abstract

L'invention concerne une machine d'étiquetage (10) comprenant généralement un système de transport permettant le transport d'un emballage (20) dans la machine d'étiquetage (10). Le système de transport est agencé pour déplacer en continu une ligne d'emballages (20) dans la machine d'étiquetage (10). La machine d'étiquetage (10) fournit également un système d'introduction étiquettes permettant l'introduction des étiquettes (11) dans la machine d'étiquetage (10), afin qu'elles soient collées sur l'emballage (20). L'étiquette (11) est entraînée dans la machine d'étiquetage (10) en au moins trois temps pendant lesquels, dans le premier temps, l'étiquette (11) est entraînée par un dispositif d'introduction central (30), un premier dispositif d'introduction latéral (32) et un second dispositif d'introduction latéral (34) ; dans le deuxième temps, l'entraînement produit par le dispositif d'introduction central (30) est supprimé et l'étiquette (11) est entraînée par le premier dispositif d'introduction latéral (32) et le second dispositif d'introduction latéral (34) ; et dans le troisième temps, l'entraînement produit par le premier dispositif d'introduction latéral (32) et le second dispositif d'introduction latéral (34) est supprimé et l'étiquette (11) est entraînée par un premier applicateur de bord latéral (60) et un second applicateur de bord latéral (61). Les étiquettes (11) sont guidées par les applicateurs de bord (14, 16) et ces derniers entraînent directement les deux parties côté latéral des étiquettes (11) vers l'avant et également sur la surface de l'emballage (20) plutôt que de guider simplement les étiquettes (11) au moyen d'une surface de guidage statique. Les applicateurs de bord (14, 16) sont agencés pour se déplacer d'une position supérieure à une position inférieure lorsque l'étiquette (11) apparaît de sous l'applicateur central (12). En conséquence, l'étiquette (11) est tout d'abord au moins partiellement collée sur la surface supérieure de l'emballage (20), puis les deux applicateurs de bord (14, 16) sont déplacés vers le bas en même temps que des courroies d'applicateur (61, 61) sont entraînées de sorte que les parties latérales de l'étiquette (11) soient entraînées vers l'avant par les courroies d'applicateur (60, 61) des applicateurs de bord (14,16) en même temps qu'elles sont également déplacées vers le bas par les applicateurs de bord (14, 16).
