Definitions

  • the invention relates to a method for disposing of flexible material which is in the form of at least one moving material web which is fed in a feed direction with a feed path speed of a disposal device, in particular for disposal of spent embossing film web during the operation of a hot stamping device.
  • a material layer to be embossed is guided in a hot embossing device at constant speed through an embossing gap which is formed between an embossing cylinder having an embossing tool and a counterpressure element, in particular an impression cylinder.
  • An embossing foil web is moved over the material layer in such a way that it moves at the same speed as the material layer during a stamping interval.
  • embossing material located on the embossing foil web for example discrete embossing units lying one behind the other, such as images or texts, or a Lucaslessness part of a color layer, transferred under the action of pressure and temperature on the material layer.
  • the embossing foil web is drawn off by a suitably formed transport device of a preferably roll-shaped film supply and moved through the embossing gap, and the spent embossing foil is carried away and must be disposed of.
  • An embossing device known from GB 2 254 586 has on the waste side a disposal device operating in the manner of a shredder or documentary printer, to which the used web material is fed by means of an upstream conveying station. This has two counter-rotating transport rollers, between which the web material is clamped and conveyed through. The discharge end of the conveyor emerging free end of the web material enters the insertion slot of the shredder, which ruptures the web material into small pieces of web material and promotes a collection container, which is emptied from time to time.
  • shredders can cause malfunctions in the cutting unit, for example due to incomplete tearing of the material or due to clogging of the cutting unit.
  • German patent DE 648 075 shows a cross cutter for paper webs with two rotating drums, one of which is partially wrapped by the web material and having a recess which is spanned by the web material, while the other has a synchronized with this drum rotating knife, which the Cutout spanning spanning web material severed.
  • a similar cross cutter, which is intended for dicing cigarette paper, is known from DE 37 30 810.
  • DE 40 21 573 A1 shows a device for removing and crushing cut strips calendered film. Between the strips of film fed to their actual use, narrow cut strips are cut out and it is the object of this device to break them up. To do this, they run between a pair of guide rollers into a cross-cutting station that works with a star-shaped knife roller. The strips have, when they run into the knife roller, a considerable distance from each other.
  • the invention has for its object to avoid the disadvantages of the prior art.
  • a method and a device are to be specified, with which a trouble-free continuous disposal especially of very thin web material, such as spent embossing foil web, is possible.
  • the invention proposes a method with the features of claim 1 and a disposal device with the features of claim 7.
  • the invention provides that the first web portion as viewed in the feed direction is at least partially adjacent to the second web portion and that the severing at an acute angle or substantially takes place parallel to the feed direction.
  • a longitudinal section or several longitudinal sections which are preferably parallel to each other and in particular performed simultaneously, it is possible to produce narrow strips of sheet material which, if appropriate, can still be shortened by means of suitable cross-sections or transverse cracks. Resulting strips can advantageously remain after the separation still in surface contact with a conveyor carrying them and thus be supplied in an orderly arrangement further disposal steps. In a brief retraction opposite to the feed direction, the longitudinal connection is maintained.
  • a first web section of the material web and a second web section of the web which is preferably arranged at a lateral distance from the first web section, can be held in place and the web can be severed in an intermediate section between the first and second web sections for producing web material pieces.
  • the pieces of web material can then be collected and possibly subjected to further processing steps.
  • embossing foil webs which are usually provided with a carrier film made of tough plastic, tend to be not or only partially incised in cutting units of conventional shredders whose cutting units are in cutting engagement with one another, because of a lack of foil tension and / or clog the reapers.
  • a further embodiment provides that the web material is severed in a between the detained track sections freely suspended and / or taut held intermediate section or separation section.
  • a complete separation can be promoted, because a separator used for separation by the Web material can completely penetrate defined surface.
  • the length of the free intermediate section may be correspondingly less than 1 cm, in particular between about 1 mm and about 5 mm.
  • a preferred embodiment provides that the first web section in the feed direction at the front and the second web section in the feed direction is behind and that the transection is transverse, in particular substantially perpendicular to the feed direction.
  • the respective front track piece can be separated and disposed of easily, while the underlying can still be held and can serve as a front piece of the subsequent separation.
  • By holding the respective rear track section is also ensured that the supplied material web can not slip out of the disposal facility, but is constantly held securely.
  • the separation or cutting behavior of the web material adapted method can be used.
  • a method in which the web material is cut for cutting with a free cutting edge that is, with a mechanical separating member that does not require a counter element, such as a counter knife or the like, for producing the separating effect.
  • Corresponding separation devices are particularly durable and wear-resistant, since in particular in the separation area levitating web material a Cutting edge only comes into contact with the (softer) web material. It is also possible that the web material is melted for transection in the intermediate region, in particular along a substantially straight melting line.
  • This variant which can be carried out, for example, by means of a hot-air blower or heated or glowing wire or the like, is particularly suitable for sheet material with thermoplastic material.
  • An advantageous variant is characterized in that the web material for transection in the intermediate region at many, preferably linearly arranged locations, preferably simultaneously, perforated and the perforations are then increased to grow together.
  • This method which can be carried out for example by means of an imprinted sawtooth blade, is particularly suitable for cutting through plastic films, requires only slight forces because of the initial punctiform action of a separating member on the film web to produce sufficient separating pressures, and can be used particularly advantageously for stretched web material in which the enlargement of the perforations can be supported in part by independently progressing cracks in the tensioned material.
  • a further embodiment provides that for holding a web portion is pressed onto a moving in the direction of pressure surface under construction of static friction or sliding friction.
  • a pressure surface of, for example, one or more square centimeters for a secure hold little force.
  • material damage to the web material which could lead to an unintentional crack, is reliably prevented by the surface engagement of the holding force.
  • a track section is so-to-say held from below, while the side facing away from the pressure surface remains free of retaining means, which in particular sufficient space for attachment of a suitable separating device can be created.
  • a pressure surface may in particular be formed by an outer surface of a revolving conveying element of a suction conveyor, for example a suction belt, in particular a suction roll.
  • the disposal may include a step subsequent to the separation of collected pieces of material.
  • a step subsequent to the separation of collected pieces of material Preference is given to a method in which, after the severing, the web material pieces are detached from a moving contact surface carrying and / or holding them. This can be done, for example, by means of a spatula, doctor blade or the like, but is preferably carried out without contact by means of at least one air flow which lifts the web material pieces from the pressure surface, in particular sucks. Blow-off and suction can also be used in combination for detachment.
  • the packing density may preferably be increased by compressing the collected pieces of web material, preferably batchwise, for example to less than one half, one quarter or one eighth of the packing volume in the relaxed, uncompressed state.
  • the compacted example in a baler waste can then be stored to save space and / or transported away.
  • the invention enables a continuous disposal of used web material, which in particular also in thin films runs smoothly, so that disposal-related stoppages can be avoided and can be increased according to the throughput of the web material processing facility.
  • a disposal device suitable for carrying out the method has a separating device which carries out a longitudinal section for severing the web material in an intermediate section or separating section situated between web sections.
  • the device may comprise first holding means for holding a first web section flat, second holding means for holding at least one second web section flat, and at least one contact surface movable in the feed direction, to which the web sections can be pressed flatly.

It is possible that the pressure surface is moved with the feed path speed, so that can build up between the web material and pressure surface stiction. It is also possible to move the pressure surface with a higher speed or excess speed relative to the supplied material, so that there is a slip between pressure surface and material web under construction of sliding friction.
  • the pressure can be made from the side opposite the pressure surface, for example, gentle on the material by means of brushes or the like.
  • the holding means are formed by a suction conveyor, in particular a suction roll, which has at least one conveying element which revolves at a feed speed or at a peripheral speed which is higher than the feed speed and has an outer surface serving as a pressure surface, to which a web section and the intermediate section or separating section comprehensive longitudinal section of the web material is sucked.
  • the pressure surface has at least one recess that can be bridged or braced by the web material and preferably extends transversely to the direction of movement. In the region of the recess, a portion of the pressed-on web material can be kept freely suspended and / or taut without any contact with the substrate, which promotes reliable separation in this area.
