Definitions

  • the invention relates to a device for coating a scoring line of a can lid with a material for reducing the risk of corrosion in the area of the scoring line.
  • Cans are increasingly being used, the lid of which can easily be torn open by the user, so that no can opener has to be used as a tool to open the can.
  • Such "easy-open" lids are provided with a scoring line along which a lid part can be separated from the rest of the lid.
  • tinplate lids which are provided with a corrosion layer, generally in the form of tinning, in order to avoid corrosion, the corrosion layer is damaged by the scoring. Corrosion of the tinplate cover can therefore start from the area of the scoring line.
  • the invention is based on the object of designing a device of the type mentioned at the outset in such a way that it is possible to coat scoring lines of any desired shape. According to the invention, this task is solved by a device of the type mentioned at the outset
  • a spraying device with a width which corresponds at least to the maximum distance between two scoring seam sections perpendicular to the direction of transport, and
  • the coating of the scoring line is carried out during translatory transport of the can lid, preferably under one or more spray heads.
  • the control synchronizes the opening of the spray nozzles in such a way that exactly at the time the scoring line sections are transported past the spray nozzles, these are open and spray the corresponding sections of the scoring line selectively, preferably with a varnish.
  • the spray duration is therefore very short if a corresponding scoring line section is oriented perpendicular to the transport direction and is longer if the scoring line section lies in the transport direction.
  • the spray nozzles are preferably arranged next to one another in a straight line.
  • the spray nozzles can be controlled with
  • Needles can be closed so that a spray head can be used, as is known in principle for ink jet printers.
  • a position sensor is provided for the can lid arriving in the area of the spray device.
  • Figure 1 is a schematic representation of a transported can lid and a spray head
  • FIG. 2 shows schematic representations for several
  • Figure 1 shows a view from below of an elongated can lid 1 with rounded corners, as used for example for canned fish.
  • the can lid 1 is provided with a closed scoring line 2 running parallel to its outer contour.
  • the lid 1 is on a
  • Transport belt (not shown) and is transported in a transport direction that corresponds to its longitudinal axis and is indicated by an arrow A in FIG. 1.
  • a spray device in the form of a spray head 3 which is attached to it
  • Spray nozzles 4 open at the bottom, which can be individually closed with needles.
  • the spray nozzles 4 extend over such a width of the spray head 3 that at least the maximum width of the area of the cover 1 divided by the scoring line 2, which is perpendicular to the transport direction A, is covered.
  • the spacing of the spray nozzles 4 from one another is chosen such that the quantities of material sprayed from the spray nozzles 4 add up to form a continuous line (approximately 2 mm wide).
  • those spray nozzles 4 which are opened due to a control - and are therefore effective - are shown enlarged.
  • all spray nozzles are effective which are arranged above the linear, perpendicular to the transport direction A - and thus in the direction of the spray nozzles 4 arranged next to one another - scoring line section 21.
  • Phases b) and c) in FIG. 2 show the passage of a rounded corner 22 of the scoring line 2, for the covering of which only one spray nozzle 4 is effective at a time.
  • phase d a straight-line section 23 of the scoring line 2 running parallel to the transport direction A is sprayed by a single spray nozzle 4.
  • the spray head 3 can expediently be equipped with industrially proven spray nozzles 4, such as are used in ink jet printers.
  • the actuation devices for the needles of the spray nozzles 4 can be designed accordingly.

Abstract

Un dispositif permet de revêtir la ligne d'ouverture (2) du couvercle (1) d'une boîte avec un matériau qui réduit le risque de corrosion dans la zone de ladite ligne (2). Afin de revêtir des lignes d'ouverture ayant n'importe quelle forme voulue, le dispositif comprend un dispositif de transport par translation du couvercle (1) de la boîte par rapport à un dispositif vaporisateur (3), un dispositif vaporisateur (3) ayant une largeur correspondant à au moins l'écartement maximal entre deux sections de la ligne de soudure formant l'ouverture, perpendiculairement au sens de transport, ainsi qu'une pluralité d'ajutages vaporisateurs adjacents (4) à commande individuelle. Une commande synchronise les ajutages vaporisateurs (4) avec le dispositif de transport, de sorte que les ajutages vaporisent le matériau, pendant le transport du couvercle (1) de la boîte, sur les sections (21, 22, 23) de la ligne d'ouverture (2) qui passent devant les ajutages vaporisateurs (4).
