Definitions

  • the invention lies in the field of monitoring and controlling with great precision the path of a strip of foil material for feeding into a processing device such as an inkjet printer, a laminator or a device which performs both said functions.
  • the invention provides a device for transporting a strip of foil material, for instance a sheet of plastic or paper, along a substantially straight path from a supply station to a processing station, for instance a printer, a laminator or the like.
  • a technically relatively simple embodiment consists of the braking means taking a mechanical form.
  • braking means comprise two rollers or pairs of rollers having brakes which are controllable by the sensing means and which engage on respectively the left side edge and the right side edge of the strip.
  • the device with the mechanical braking means has the special feature that the braking means comprise two co-acting rollers which can be braked and which extend in transverse direction over substantially the whole width of the strip, the relative angular positions of said rollers being controllable in a vertical plane by the sensing means.
  • the braking means take a pneumatic form and comprise two suction nozzles in respectively the zone of the left side edge and the right side edge of the strip, which suction nozzles are each connected to underpressure means, wherein the operation of the suction nozzles is controlled by the sensing means.
  • the sensing means can take for instance a mechanical or optical form. In these cases the sensing means are separate components subject to possible malfunction, which can have a fundamental influence on the proper operation of the device.
  • the device does not have separate sensing means, is given a fully self-adjusting form but is nevertheless able to control the path of the foil strip within very narrow tolerances.
  • a preferred embodiment has in this respect the special feature that the suction nozzles are positioned or can be positioned such that their outer boundaries are situated a chosen distance outside the nominal path, and each of the suction nozzles is connected to an individual underpressure source such that the sensing means and the braking means are integrated.
  • an embodiment can be useful wherein the transverse positions of the suction nozzles are adjustable.
  • another embodiment has the special feature that the strip is transported over the surface of a plate, on which surface the suction nozzles debouch.
  • each suction nozzle comprises a number of perforations, for instance slots, recessed into a part of said surface.
  • the use of a number of perforations in a guide surface has the advantage that a relatively large suction area, and thereby a relatively great suction and braking force, can be combined with a good support in the zone of the suction nozzle, whereby local deformation of the foil strip is avoided.
  • each suction nozzle comprises a number of slots extending with a considerable directional component transversely of the transporting direction of the strip.
  • each suction nozzle is embodied in a block consisting of an upper plate provided with the perforations and a connecting block which is connected airtightly thereto and which connects the perforations to a common connection for an underpressure source.
  • the device can be readily added to an existing processing device such as a printer or laminator.
  • the device according to the invention can also be integrated with such a processing device.
  • Said block can be embodied for instance as injection moulded article consisting of plastic or aluminium, of glass-filled PVC or PC, of cast PU, of aluminium modelled by milling or other machining, of steel or of other suitable materials or combinations thereof.
  • the said friction reduction can be realized by a coating consisting of titanium nitride or a plastic such as PTFE.
  • Fig. 1-4 show a device 1 according to the invention.
  • a paper strip is carried out of a supply tray 3 in a direction 4 to a partly drawn device, for instance a laminator. It is carried for this purpose through the pinch of laminating rollers 5, 6 via a flat support plate 7.
  • Respective suction nozzles 8, 9 are positioned in the edge zones of the nominal path of strip 2.
  • Fig. 5 and 6 show nozzle 9 on larger scale, so that the details can be seen better. It is apparent that the left side edge 10 and right side edge 11 have a mutual distance corresponding to the width of paper strip 2, that the suction slots 12 to be described hereinbelow of suction nozzles 8 and 9 can never be simultaneously covered by paper strip 12.
  • Fig. 1-4 show the nominal position of strip 2 relative to suction nozzles 8, 9. Suction nozzles 8, 9 are connected via respective suction lines 19, 20 to suction means (not shown), particularly fans. In the situation shown in Fig.
  • the shown distance over which the suction slots 12 of the two nozzles 8 and 9 extend outside side edges 10, 11 in the shown nominal situation determines the tolerance within which the running of paper strip 2 can be held constant.
  • positions of nozzles 8, 9 can be adjustable for the purpose of adaptation to the width of the paper strip.
  • Fig. 7 and 8 show the possible construction of a suction nozzle 9, which can be identical to nozzle 8.
  • An upper plate provided with the slots 12 is covered airtightly on its underside by an intermediate plate 15 which is connected thereto and has a row of perforations 16 which are in register with slots 12.
  • a hollow connecting block 17 connects airtightly to perforations 16, which block is embodied as a trough with a passage and a connection 18 which can connect the cavity to suction line 20.
  • the structure according to the invention provides a superior transporting accuracy, wherein deviations from the nominal path can be reduced to negligible proportions.
