Definitions

  • the present invention regards a glue application unit for a labeling apparatus for applying glue on labels prior to their application on receptacles, such as containers, bottles, cans or the like.
  • the packaging of food or non-food products into respective receptacles comes along with a labeling of the receptacles with respective label sheets during a labeling process.
  • the label sheets serve e.g. to transmit the respective brand of the packaged product and, thus, to draw the attention of final customers once the product has been delivered to and exposed in store houses. Additionally, each label sheet provides the customer with important information about the stored product.
  • the overall appearance of the label sheet applied on a respective receptacle is of significant importance. Thus, the quality of the labeling process itself must guarantee a correct, repeatable and clean attachment of the label. Otherwise, a significant number of receptacles are discarded leading to increasing production costs.
  • labeling of the receptacles is realized before, during or after filling of the receptacles themselves.
  • a succession of receptacles is advanced along a predetermined receptacle path towards a receptacle treatment apparatus, such as a labeling apparatus, which is adapted to label each receptacle.
  • the respective label sheet originates from an endless web of label material.
  • the endless web is fed along a predetermined label material path at first to a cutting unit, in which the endless web is cut in order to obtain a succession of single label sheets with predetermined sizes and finally this succession of single label sheets is fed into the receptacle treatment apparatus, in which each label is attached to one respective receptacle.
  • a defined layer of glue is applied onto the backside of such label sheet by means of a glue application unit.
  • a typical glue application unit comprises:
  • the glue distribution bar needs to be correctly aligned and positioned with respect to the glue roller so that the central axis of the glue roller and the extension axis of the glue distribution bar are parallel to one another and the glue distribution bar is placed adjacent to the glue roller.
  • the alignment and the positioning of the glue distribution bar must allow for the correct formation of a veil of glue between the glue distribution bar and the glue roller as otherwise the glue cannot be correctly transferred onto the glue roller which would inevitably lead to a significant reduction of the quality of the overall gluing process.
  • the glue distribution bar must be positioned and aligned in such a manner that, in use, unwanted contacts between the glue roller and the glue distribution bar are avoided as also these lead to a significant reduction of the overall gluing process.
  • the relative positions and alignments between the glue roller and the glue distribution bar must remain stable and must not be subject to variations.
  • the admitted tolerances are minimal which means e.g. that the production of the glue roller and the glue distribution bar must be very accurate.
  • the tolerances between the orientations of the glue roller and the glue distribution bar are minimal; i.e. the rotation axis and the extension axis cannot significantly deviate from being parallel to one another.
  • the alignment of the glue roller and the glue distribution bar often relies on a first alignment step and then on operation of the glue roller without the application of glue for preparing the glue distribution bar to the specific glue roller by wearing off of the glue distribution bar for finally, obtaining the desired alignment and arrangement of the glue distribution bar with respect to the glue roller.
  • Number 1 in Figure 1 indicates as a whole a glue application unit for a labeling apparatus 2 (only partially shown to the extent necessary to the comprehension of the present invention) adapted to apply a layer of melted glue on single label sheets 3 to be stuck on respective receptacles (known per se and not shown), such as bottles, containers, vessels, cans etc.
