Definitions

  • the invention relates to a device for cutting stacked, sheet-like material according to the features contained in the preamble of claim 1.
  • Such a device is known from DE 36 13 316 C1, which is used as a second cutting device of a cutting system, in which a first cutting device is designed for the production of block strips by parallel longitudinal cuts, while the block strips are cut in the transverse direction with the second cutting device that individual blocks are created.
  • a disadvantage of the known system is that two cutting devices are required to cut the block strips, which results in high system costs.
  • the device should also make it possible to carry out conventional cutting operations, that is to say main, edge and intermediate cuts.
  • a defined position is not mandatory under the working situation to understand the first ruler, but several positions of this ruler are conceivable with respect to the first field region of the starting field.
  • the desired different functions can be accomplished with the device.
  • the device With the second field area lowered, which in this position forms a plane with the first field area and the working field and the input field, the device operates in accordance with the device described in European Patent 0 056 874.
  • the first and the second field area hereby form a unit which can be moved in the direction of advance of the material to be cut and can be moved in the opposite direction, with the possibility of creating a gap between the latter and the working field for the disposal of the chips resulting from an edge or intermediate cut.
  • the second ruler When the second ruler is moved into its working position after opening the gap, this ruler completely pushes the cut benefit, which due to the inevitably recessed position of the cutting bar and the cutting knife, extends beyond the first field area onto the starting field, so that it does not get caught when the gap is closed again can be.
  • the second ruler ensures that the chips are disposed of through the gap and are not thrown onto the starting field.
  • the cut panel can be freely manipulated on the exit field; the second ruler in the working position also allows the panel to be aligned with it.
  • the device fulfills the function of the second cutting device of the system described in DE 36 13 316 C1 when the second field area is raised and the second ruler is in the working position.
  • the first ruler is brought to its working height at which it is above the level of the first field area located, in particular at the bottom with the level of the first field area and consequently a benefit located in the first field area can be manipulated by the latter.
  • a transverse channel is formed by this and the second ruler, through which the benefits, for example individual blocks of a block strip, can be fed to the further processing station by means of the movable ejector.
  • the width of the transverse channel can be changed by a corresponding adjusting movement of the first ruler perpendicular to the cutting plane.
  • the first ruler can be mounted differently, for example on the underside of the second field area or also on the top of a bearing part which is arranged parallel to the second field area below it, the first ruler being arranged between the bearing part and the second field area.
  • the second field area and the bearing part are expediently connected to one another, in particular by lateral webs, so that they can be raised and lowered with one another.
  • the second ruler In order to be able to form a different width of the transverse channel, the second ruler, regardless of its mounting, should be arranged in the feed direction of the material to be cut and displaceable in the opposite direction.
  • the assembly of the first ruler in the bearing part for the second field area is considered to be the preferred embodiment, since in this case the storage and travelability of this ruler can be accomplished most easily.
  • the first ruler should also be able to be moved into the area of the first field area, wherein a transverse channel width can only be achieved in the first field area up to one that extends over the first field area.
  • a transverse channel width can only be achieved in the first field area up to one that extends over the first field area.
  • the maximum transverse channel width is defined by the position of the first ruler in its end position moved away from the first field area.
  • the area of the device according to the invention is expediently designed such that in a base frame a first table part is mounted horizontally in the direction of advance of the material to be cut and can be moved in the opposite direction, this table part accommodating the first field area of the exit field and lifting and lifting a second table part in the first table part is lowerable, which accommodates the bearing part arranged parallel to one another and the second field area of the starting field.

  • the second table part is advantageously mounted in vertical guides of the first table part and the lifting elements for lifting and lowering the second table part act on a base for the second field area which can be removed from them and also on the first table part.
  • Special embodiments of the device relate to the arrangement and travelability of the two rulers and in particular to the design of the second ruler.
  • the first ruler serves the purpose; depending on the width of the cut panel to form a correspondingly wide transverse channel, it is necessary to arrange this ruler in the feed direction of the material to be cut and in opposite directions.
  • this ruler should be movable between an end position assigned to the first field area and an end position assigned to the bearing part and in its working position should be substantially perpendicular to the table surface.
  • the first ruler is also advantageously pivotably mounted between two working position positions, it being shown in a first position essentially corresponding to the slope and in a second position it is essentially perpendicular to the table surface.

Abstract

Un dispositif de découpage de feuilles empilées comprend une surface de support formée d'un champ d'admission (4) qui reçoit les feuilles (5) à découper, d'un champ de travail (3) au-dessus duquel sont agencés une lame de coupe (10) et un sommier de serrage (9), suivi d'un champ de sortie (22, 32) qui reçoit les feuilles découpées. Le champ de sortie est subdivisé en une première zone (22) adjacente au champ de travail (3) et en une deuxième zone (32) située en aval de la première. Une première règle (41) est agencée sous le champ de sortie à la hauteur de l'interface entre les deux zones (22, 32). La deuxième zone (32) peut être soulevée au-dessus d'une position où elle forme un seul plan avec la première zone (22). La première règle (41) peut elle aussi être soulevée et mise dans une position de travail où elle coopère avec la première zone (22) du champ de sortie. L'ensemble du champ de sortie peut se déplacer perpendiculairement au plan de découpage (13), créant un écartement entre le champ de sortie et le champ de travail.
