Definitions

  • Edge-side trimming of a material web in the form of a plastic film web are known.
  • the edge-side trimming of such a material web is customary in order to produce a clean edge area of the material web and, for example, to change or eliminate width fluctuations.
  • edge strips are produced by a continuous cut in the longitudinal direction, it is necessary at the beginning of the cutting process that above all the end of the edge strip, i.e. H. also to cut transversely to the longitudinal direction L the area in which the longitudinal cutting knife first entered the material web to cut the same.
  • the DE 20 2011 004 608 U1 shows a device in which a longitudinal cutting knife continuously cuts the material web into a partial web and an edge strip.
  • the longitudinal cutting knife creates an incision which at the same time forms the boundary between the partial web and the edge strip.
  • the transverse severing of the material web, in particular the edge strip is carried out by a transverse severing knife which has a cutting blade and a separating device which, before the transverse severing of the edge strip, separates the edge strip from the partial web.
  • the cutting blade As the cross cutting knife approaches the material web, the cutting blade finally cuts through the edge strip, the material web fed further in the longitudinal direction L running onto the cutting blade in the area of the edge strip, accumulating there and being forcibly fed to the removal device.
  • the object of the present invention is to provide a device and a method which enable the material web to be transversely severed simply, reliably and safely even at high web speeds.
  • transverse severing or transverse severing is understood to mean severing the remaining web (edge strip) transversely to the longitudinal direction of the fed material web.
  • the removal device is suitable - without external assistance - to remove the remaining web after the transverse cutting.
  • the removal device ensures automatic drawing in and removal of the remaining web.
  • a negative pressure prevails in the discharge device, so that the remaining web is automatically sucked into the discharge device after the transverse separation.
  • the present invention has the advantage that a large number of partial webs can be produced and the removal device can simultaneously remove several remaining webs that arise when the material web is trimmed.
  • An essential advantage of the invention is that the remaining web is separated from the partial web well before the cross-cutting device. This means that after a transverse separation, the remaining web is separated from the partial web well in front of the cross-cutting device, so that the edges of the remaining web are prevented from contacting the edge of the partial web and thus negative edge effects or edge defects arise.
  • the discharge device has several discharge channels in order to suck away several residual webs, in particular that the position of the discharge channels in relation to the material web can be changed.
  • the removal device advantageously has a pressure medium which creates a desired negative pressure in order to reliably suck off the remaining webs.
  • the pressure medium can, for example, be a fan that works centrally for each discharge channel. It can also be provided that each discharge channel has an individual pressure medium.
  • the position of the discharge channels can be changed individually with respect to one another, which depends on the position of the longitudinal cut on the material.
  • the discharge channels can be displaced manually or automatically via actuators, so that full automation of the device according to the invention is conceivable.
  • the discharge device can have at least one funnel which is designed with an inlet in order to discharge the remaining web.
  • Each discharge channel advantageously has an individual funnel in order to discharge the remaining web at its inlet.
  • a corresponding negative pressure is set in the funnel during the automatic trimming of the material web, whereby the remaining web is automatically sucked through the inlet of the funnel.
  • the term “funnel” is to be understood as a component that does not necessarily have a changing cross section.
  • the funnel has a constant cross-section or varying cross-sections.
  • the term “funnel” can be equated with the term "nozzle”.
  • the discharge device can be positioned on a first roller, which ensures the transport of the material web, in particular the geometry of the funnel in the area of the inlet being at least partially adapted to the geometry of the first roller.
  • the first roller can, for example, further transport the partial web or partial webs, with a corresponding deflection of the transport direction of the partial web or partial webs taking place on the first roller, for example.
  • the longitudinal cutting device is advantageously located upstream of the first roller, the transverse cutting device being located downstream of the first roller. So that the remaining web is reliably removed from the removal device, the removal device is located as close as possible to the first roller.
  • the first roller preferably has a cylindrical shape and rotates about an axis, the geometry of the funnel in the area of the inlet being designed like a segment of a circle.
  • the funnel can thus be guided as close as possible to the first roller, whereby a corresponding negative pressure is established within the funnel, which makes it possible to automatically pull the remaining web into the removal device after the transverse separation.
  • the invention can provide that a feed roller is arranged inside the funnel in order to remove the remaining web in an improved manner.
  • the feed roller which is also mounted about an axis of rotation, is advantageously located inside the funnel and captures the remaining web after a transverse separation has taken place outside the discharge device.
  • the rotation of the feed roller results in active conveyance or active transport of the remaining web in the direction of the discharge channel, with the pressure medium of the discharge device advantageously also providing a corresponding negative pressure within the respective funnel.
  • the rotation of the feed roller results in an even tension in the remaining web and reliable separation of the remaining web from the partial web. It can advantageously be achieved in this way that negative edge effects on the partial web and / or on the remaining web as well as the undercutting of the partial web by the remaining web is avoided.
  • the feed roller can extend through a large number of hoppers arranged adjacent to one another, each hopper in particular having an opening.

  • a measure improving the invention can provide that the feed roll is rotatably arranged inside the funnel in such a way that a first air flow flowing below the draw roll forms a second air flow flowing above the draw roll. It is conceivable that the feed roller is arranged inside the funnel in such a way that the first air flow reliably pulls the remaining web into the funnel from the outside.
  • the second air flow which flows above the feed roller, causes the remaining web to be reliably detached from the rotating feed roller.

  • the underpressure within the funnel can be increased via the closing element in the closed position, with an interruption in the tension in the material web during transverse cutting being reduced at the same time.
  • the closing element is advantageously in the closed position during transverse cutting. If the start of the remaining web is inside the removal device and is reliably removed there, in particular by the feed roller, the closing element can be moved into the open position in order to bring about an additional air flow into the interior of the funnel. In this way, the power of the pressure medium can advantageously be reduced during operation in order to generate the same volume flow.
  • the invention comprises that the cross-cutting device is arranged in the area of the inlet, in particular downstream of the first roller. Via the negative pressure inside the funnel, the remaining web is pressed against the cross-cutting device and finally separated from it there so that the beginning of the remaining web is automatically sucked into the funnel and is accordingly captured by the air flow.

  • the auxiliary roller is preferably in the first position so that no material web tension drops, cut interruptions, web breaks, etc. occur during transverse cutting. If transverse cutting takes place, there is no interruption in the tension in the material web, which would be disadvantageous, in particular in the area of the longitudinal cutting device.

  • the other features of the embodiment according to Fig. 5 correspond to the explanations from the previously described FIGS. 2 to 4 .
  • the cross-cutting of the remaining web 4 takes place with a time delay to a longitudinal cutting of the longitudinal cutting device 60.
  • the pressure within the funnel 12 can be adjusted, among other things, by the closing element 14, which can be moved between the closed position 21 and the open position 22. Before the residual web 4 is severed transversely, the closing element 14 assumes the closed position 21. If, after a defined time, the remaining web 4 is reliably discharged via the discharge device 10, the closing element 14 is transferred into the open position 22, whereby a supporting compensating air flow flows into the funnel 12 via the opening 19. This equalizing air flow can, inter alia, cause it to merge into the second air flow 18 or trigger improved flow effects within the funnel 12.
  • the discharge channels 11 are mutually displaceable in the longitudinal direction of the axis of rotation of the first roller 31, so that the distance between the Discharge channels 11 is adjustable.
  • the material web 2, which is transported over the rollers 31, 32, can be cut in the most varied of ways, with residual webs 4 formed at the edge of the material web 2, which can also be referred to as edge strips.
  • the funnels 12 are designed to be widened, in particular on the left and right, in order to be able to suck off wider residual webs 4.
  • narrower funnels 12 are provided in order to suck off residual webs 4 which are narrower. These narrower remaining webs 4 can also be referred to as median strips.
  • the suction space 26 can accommodate all of the edge strips and median strips in order to feed them back into the overall process or to pass these remaining webs on for disposal.
  • the suction space 26 has several separate cavities, for example the widened discharge channels 11, which are arranged on the left and right, open into a first cavity, and the narrower discharge channels 11 open into a separate second cavity.
  • the operator of the device 1 according to the invention is thus free to “further process” the remaining webs 4 within the separate cavities of the suction space 26 according to the corresponding requirements. This means that certain residual webs should be fed back into the overall process, for example, or certain residual webs should be disposed of.
  • each funnel 12 has an opening 28 through which the feed roller 16 extends, the geometry of the opening 28 essentially corresponding to the geometry of the feed roller 16.
