Definitions

  • the invention relates to a transport device for the transport of a web, in particular for the transport of an exposed or exposable hologram film.
  • a web made of paper or another printable medium can also be considered as a web.
  • Such a transport device can be used, for example, to feed a film to an exposure machine, which can be a hologram film or holofilm which is provided with a structure, in particular a hologram, by means of the exposure machine.
  • an exposure machine which can be a hologram film or holofilm which is provided with a structure, in particular a hologram
  • Such a transport device can also be used on the output side of the exposure machine in order to transport an exposed hologram film further and then wind it up.
  • the film must always be kept taut both during winding and unwinding, which sometimes even requires the film to be tightened more. This can be done by appropriate rollers that are driven. It has been found to be disadvantageous that buildup or contamination on the rollers cause marks on or on the surface when the holofilm is pulled through.
  • the transport device for the transport of a web is characterized in particular by a rotatingly driven or drivable drive roller. It also includes a cleaning roller which serves to clean the drive roller and is rotatably mounted about its longitudinal axis and which can be applied directly to one side of the drive roller and which is not covered or covered by the web fed to the drive roller. In other words, the cleaning roller is applied directly to the drive roller from one direction such that no web or hologram film lies between the drive roller and the cleaning roller.
  • the cleaning roller has a greater adhesive force than the drive roller.
  • a pressure roller mounted on a swivel lever and rotatable about its longitudinal axis, which is designed to press the web onto the drive roller.
  • the web is thus pressed against the driven drive roller in order to ensure that the web or the hologram film is reliably carried along.
  • the pressure roller itself does not have to be driven for this; it runs with the rotation of the drive roller or is taken along by the web.
  • a pressure roller which is driven in synchronization with the rotation of the drive roller in particular, can also be used.
  • the swivel lever can be pivoted, in particular pneumatically, hydraulically or by an electric motor, between a pressure configuration in which the pressure roller presses the web against the drive roller or in which it is itself pressed against the drive roller, and a release configuration in which the pressure roller does not press the web against the drive roller or it is itself pressed against the drive roller.
  • the actuation of the swivel lever between the two configurations ensures that a web or a hologram film can be reliably threaded in without any kinks or the like being caused thereby.
  • the pressure is preferably maintained during operation, which at the same time specifies the pressure with which the pressure roller is pressed onto the drive roller. This contact pressure can be adjusted depending on the material selected.
  • a second cleaning roller which is rotatable about its longitudinal axis and serves to clean the pressure roller, which is on one side of the Pressure roller can be put on or put on directly, which is not covered or covered by the fed web.
  • the second cleaning roller is applied directly from a further direction to the pressure roller, such that no web or hologram film lies between the pressure roller and the second cleaning roller.
  • the second cleaning roller has a greater adhesive force than the pressure roller.
  • the pressure roller is mounted on a swivel lever, it has proven to be advantageous if the second cleaning roller is also mounted on this swivel lever of the pressure roller.
  • the cleaning roller can contact the pressure roller in any pivot position of the pressure roller and cleaning can also be carried out in the release configuration.
  • At least one, preferably both, of the cleaning rollers are mounted on a bearing device which comprises a base plate and two legs extending from the base plate, between which the cleaning roller is rotatably mounted.
  • This storage device offers reliable storage of the cleaning roller, which is bordered on both sides by the legs.
  • the legs each have a, in particular rectilinear, backdrop for guiding slides attached to the cleaning roller.
  • the cleaning roller can thus be mounted so that it can be adjusted in the direction of extension of the legs, for example in order to be mounted in a suitable manner on drive rollers of different diameters.
  • At least one, preferably both, of the cleaning rollers are at least partially resiliently mounted in a direction of extension of the legs or under a spring preload. This pretensioning means that the cleaning roller is pressed against the drive roller or the pressure roller with a predetermined force.
  • this spring preload can also be advantageous in an alternative or supplementary configuration of the bearing device with a swivel device.
  • the bearing device in particular its base plate, to have a swivel device which is designed to mount the bearing device rotatably about an axis of rotation.
  • the bearing device can be applied to the drive roller or to the pressure roller together with the cleaning roller by motor or manually.
  • the springs exerting the spring preload ensure that when the cleaning roller is pivoted, the drive roller or the pressure roller abuts without this acting on the dead center due to an acting weight force is guided between the two rollers and could thus get out of contact with the rollers to be cleaned.
  • At least one, preferably both, of the cleaning rollers are mounted on a bearing axis, and if the bearing axis is releasably fixable between the two legs of the bearing device by means of a lever is.
  • the carriage facing away from a housing of the transport device has a passage, in particular a thread-free passage, through which the bearing axis is or is guided.
  • the carriage facing the housing is then formed, for example, with a thread, in particular with an internal thread, into which an external thread of the bearing axis is screwed, or is actuated by the lever on the end of the bearing axis facing away from the housing.
  • the cleaning roller and / or the second cleaning roller is formed from an elastomer, in particular from an elastomer with adhesive properties.
  • the roller can also be coated with an adhesive film in order to ensure a sensible cleaning of the drive roller or the pressure roller.
  • the cleaning roller is then designed as an adhesive roller. Reliable cleaning can also be brought about by the fact that the drive roller is also made of aluminum or a suitable aluminum alloy. The use of aluminum or a suitable aluminum alloy results in a suitable material combination with the material of the cleaning roller, which contributes to a good cleaning of the drive roller.
  • the web or the film is conveyed by a rotatingly driven or drivable drive roller 102, wherein a continuous but also clocked rotation of the drive roller 102 is possible.
  • the drive roller is fixed to a housing 138, in particular on the housing front 140, by means of a flange which has a feedthrough to a motor, for example an electric motor or a pressure medium-operated motor, through which the drive roller 102 can be driven in rotation.
  • the device 100, in particular the motor has a braking device which ensures that the web or the hologram film 200 cannot be pulled back again.
  • the transport device 100 is formed with an integrated cleaning device comprising a cleaning roller 106.
  • This cleaning roller 106 is used to clean the drive roller 102, for which purpose the cleaning roller 106 is also rotatably mounted about its longitudinal axis 104 and during the rotation of the drive roller 102 also rotates or is carried by it.
  • the cleaning roller 106 is applied directly to the drive roller 102, specifically on one side or in a region of the drive roller 102 that is not covered or covered during operation by the web fed to the drive roller 102.
  • the cleaning roller 106 is formed from an elastomer, preferably an elastomer with adhesive properties, so that any buildup or dirt on the drive roller 102 is detached from the cleaning roller 106 and taken away by it.
  • a pressure roller 112 is additionally provided for the safe transport of the web or the hologram film 200.
  • the pressure roller 112 is mounted on a swivel lever 108 and can also be rotated about its longitudinal axis 110, it being designed to press the web onto the drive roller 102.
  • the pressure roller 112 is rotatably fixed to an arm of the pivot lever 108, the pivot lever 108 or this arm being pivotable between a pressure configuration in which the pressure roller 112 presses the web against the drive roller 102 and a release configuration in which the pressure roller 112 presses the Do not press web against drive roller 102.
  • a pneumatic drive is provided for adjusting the swivel lever 108, for which purpose a corresponding pressure connection 142 is provided on the side of the housing 140. Together with the braking device of the device 100, retraction of the web or the hologram film 200 is reliably prevented by the pressing force of the pressing roller 112.
  • the pressure roller 102 is also assigned a second cleaning roller 116 which is rotatably mounted about its longitudinal axis 114, in order to clean the pressure roller 102 from one side or in an area which is not covered or covered by the fed web.
  • the second cleaning roller 116 is shown stored in a maintenance or service position in which it is not in contact with the pressure roller 112.
  • the second cleaning roller 116 causes the pressure roller 112 adhering dirt detached from the second cleaning roller 116.
  • the second cleaning roller 116 is also fixed on the pivot lever 108, in particular on a second arm of the pivot lever 108, so that cleaning can also take place when the pressure roller 112 is in the release configuration.
  • the second cleaning roller 116 is formed from an elastomer, preferably an elastomer with adhesive properties, so that any adhesions or dirt on the pressure roller 112 are detached from the second cleaning roller 116 and taken away by the latter.
  • both cleaning rollers 106, 116 are mounted on a bearing device 118, each of which comprises a base plate 120 and in each case two legs 122 extending from the base plate 120.
