Definitions

  • the present invention concerns a method and an ap- paratus for the foil packaging of newspapers and similar printed articles which e.g. are fed from a rotary printing press with high capacity. It is known to carry out such a packaging in the formation of stacks of newspapers from which the newspapers can be fed through a packaging station with considerably smaller capacity, but with the invention it is aimed at carrying out the operation on an in-line basis, e.g. with a capacity of 25-30,000 items per hour, i.e. up to 10 items per second.
  • this can be achieved by the execution of the method as disclosed and characterised in claim 1.
  • the printed articles will hereby be subject to a certain "period of rest" against a relatively firm supporting surface in the plant, i.e. the surface of the drum, which in a simple co-rotating manner can present the necessary tools respectively for a transverse welding together of the opposing webs of packaging foil bet- ween the successively-fed printed articles, and a cutting through of the relevant connection areas.
  • fig. 1 is a schematic side view of a machine according to the invention
  • fig. 2 is a sectional view of a feeding drum used herein
  • fig. 3 is a perspective view of a set of tools housed in the drum .
  • this machine has a drum element 8 with a pressure belt 10 which runs over rollers in the form of a feed-in roller 12, a feed-out roller 14 and a pair of outer return rollers 16, and bearings 18 for supply rollers 20 for two packaging foil webs 22 and 24, which via uppermost, mutually separated rollers 26 directly under the point A are guided downwards in V-formation to run on the feed-in roller 12 under pressure from a counter-pressure rol- ler 28, after which the webs which are now brought together are fed around the drum 8 in under the pressure belt 10 or band corresponding hereto.
  • the drum 8 is configured with a number of longitudinal welding jaws 36 with a distance along the periphery of the drum corresponding to slightly more than the hanging extent of the newspapers 2.
  • a counter-pressure roller 40 or several of such rollers can if necessary create increased wel- ding pressure in against the drum.
  • one or more welding wheels 42 are arranged at both sides outside the pressure belt 10.
  • the newspapers will successively fall down in the upper V-space between the foil webs 22 and 24, in that the rate of feed is adjusted in such a manner that there will arise a free interval between the descending newspapers, e.g. in the order of 5 cm.
  • the newspapers are clamped in between the foil webs and via the roller 12 pass down to run around the drum 8. This is carefully synchronised in order to achieve that the said interval between the newspapers will come to lie directly opposite the welding jaws 36, which can therefore possibly project slightly out from the drum, possibly in a movable manner.
  • this will make it possible for the two foil webs to be held together and herewith welded together in the said interval.
  • the welding wheels 42 will serve to provide side- edge closures of the passing holsters, and these wheels will have better conditions for creating regular welding-together lines, in that they work outside that area where the thickness of the assembled web varies appreciably during the pas- sing of the newspapers and respectively the said interval between them.
  • the end products designated 32 will consist of individually holster-packaged newspapers, which are delivered to the conveyor 34 in the same number per period of time as that at which the newspapers arrive on the gripping conveyor 4. It can hereby be natural that the products are laid out on the conveyor in a scale-like manner, and the conveyor can thus work with a lower transport speed .
  • Suitable controlling and damping means can be placed at the discharge from discharge roller 30.
  • the apparatus as indicated includes reserve supply rollers for the foil webs, it will be a simple operation to carry out a change of rollers when the operative roller is about to become empty, in that a welding of the new foil web to the preceding web can thus be effected. To the extent that this takes time with a stopping of the apparatus, the dropping of the newspapers at A can be suspended until the apparatus is operative again, and the hereby surplus newspapers can be collected together for delivery in the non-packaged state .
  • the welding jaws 36 can be disposed on mutually separate support rails 44 which are locally connected by means of yoke pieces 46 exten- ding inwardly in the drum 8. If desired, the jaws can thus be movable radially in relation to the drum, e.g. by connection to a control cylinder 48.
  • a knife beam 50 with a protruding, serrated knife blade 52 which, e.g. by means of control cylinders 54, will be displaceable outwards for the cutting-over of the foil 22,24 centrally between the welds which are effected by the welding jaws 36.
  • This displacement with subsequent retraction should be effected just before the arrival at the discharge roller 30, i.e. by a quite fast operation, and therefore it can be preferred to replace the cylinders 54 with e.g. cam- controlled push-rods. It can also be a possibility to use a knife which can be moved axially.

Abstract

Cette invention se rapporte à l'emballage de journaux sous minces feuilles individuelles. Les journaux sont acheminés à partir d'une presse d'impression rotative à forte capacité, dans une position suspendue à un transporteur à pince qui amène les journaux à tomber dans un espace libre en forme de V situés entre deux bandes de feuilles minces (22, 24), lesquelles sont ensuite acheminées l'une contre l'autre, dans une bande transporteuse à pression de retenue (10), jusqu'à effectuer un cycle partiel autour d'un tambour (8). Les feuilles minces sont acheminées à une vitesse telle qu'un petit intervalle déterminé se crée entre les journaux arrivant successivement entre les deux bandes de feuilles minces. Le tambour (8) est doté de mâchoires de soudage intégrées (36), dont le mouvement est synchronisé à l'intérieur de l'intervalle pour permettre le soudage transversal des bandes de feuilles minces entre les journaux, et des cylindres de soudage externes (42) effectuent un soudage longitudinal le long des bords latéraux des bandes de feuille minces. Les bandes de feuilles minces sont découpées le long des soudures transversales au moyen de couteaux tournant conjointement sur le tambour, et, lors de leur passage dans un rouleau d'inversion (14) pour la bande transporteuse à pression de retenue (10), les journaux emballés individuellement sont déchargés sur un transporteur jusqu'à leur prochaine étape de transport.
