Definitions

  • the invention relates to a cutting machine for cutting stacked, sheet-like material, with a table for supporting the Guts on a table surface of the table, a arranged above the table surface, lowerable pressing beam, an elastic plate-shaped element that the press beam on the table surface facing side is covered and connected to the pressing beam, for clamping the Guts when lowering the Press beam between the elastic member and the table, further comprising a above the table surface and adjacent to the pressing bar arranged knife for cutting the Guts, with a cutting plane of the knife perpendicular to the table surface, and with a feed device for the material to be cut, which adjacent above the table arranged the table surface and is movable perpendicular to the cutting plane.
  • a cutting machine for cutting stacked, sheet-shaped Good is from the DE 31 01 901 A known. It has a table for placing the Guts on a table surface of the table and arranged above the table surface, lowerable pressing beam.
  • the press beam serves to clamp the material when lowering the press beam between itself and the table.
  • a knife is provided above the table surface and adjacent to the pressing beam for cutting the material in a cutting plane perpendicular to the table surface.
  • plan cutting machine With such a plan cutting machine a variety of materials are cut, formed for example from printed or non-printed sheet cuboid pile.
  • the sheets each consist in particular of paper, cardboard, plastic film and the like.
  • the stack to be cut is formed from a plurality of successive leaves, possibly from up to a thousand superimposed leaves.
  • the material properties of the sheets from which the stacks are formed when pressing the stack by means of the press beam, that the press beam more or less compresses the stack, wherein in the region of the stack, which is not acted upon by the press beam and adjacent thereto, the stack has a greater thickness.
  • the press beam more or less compresses the stack, wherein in the region of the stack, which is not acted upon by the press beam and adjacent thereto, the stack has a greater thickness.
  • a cutting machine of the type mentioned is essentially from the GB 935,863 known.
  • the elastic element is arranged between the press beam and the material to be cut in order to be able to exert a uniform pressure when pressing the material to be cut on an irregular, in particular corrugated stack surface.
  • Such an irregular stacking surface is in particular present when the stack is formed from individual printed sheets.
  • the pressure causes a slightly thicker formation of the respective arc in the region of pressure, so that when a plurality of sheets lie on one another, the accumulation of material due to the pressure adds up to a wave-shaped formation of the upper surface of the stack.
  • a cutting machine for cutting stacked, sheet-shaped Good is described.
  • This has a press bar, which receives on its side facing away from the cutting plane of the cutting machine, adjacent to the underside of the press beam, a hold-down plate, wherein between this holding plate and the pressing beam, a rubber buffer is effective.
  • the hold-down plate presses adjacent to the press bar onto the material to be cut, whereby the hold-down plate of the pressing bar on the back of the press bar caused distortion of the stack of cutting material follows and after lifting the pressure brings the stack back into the old position.
  • Object of the present invention is to develop a cutting machine of the type mentioned so that damage to the material to be cut during pressing by means of the press bar is safely avoided.
  • the design of the cutting machine according to the invention causes the elastic element to already protrude above the press beam on its side facing away from the cutting plane when the press bar is lowered in the direction of the material to be cut, in particular of the cut material stack to be cut. This has the consequence that when increasing the pressing pressure on the material to be cut, the elastic element not only continues to protrude with its side facing away from the cutting plane on the press bar, but the top sheet or the top sheet of the stack of cutting material to this projecting portion of the Cling to the elastic element.
  • the elastic element thus lies not only in the area of the press beam, but also in the region protruding beyond the press beam on the uppermost sheet of the stack of cuts and conditions when raising the press beam after the cut, that this uppermost sheet is transferred to its initial position, thus in his returned to the feed device position is returned.
  • the formation of the elastic element which already projects beyond the pressing beam on its side facing away from the cutting plane when the pressing beam is not lowered, makes it possible to machine the pressing beam or a lower pressing beam section with which the elastic element comes into contact.
  • This area of the press beam which is usually a metallic part, does not require extensive deburring to prevent damage to the material to be cut.
  • edges of the press beam which are arranged on its underside and which contact the elastic element, are not rounded, in particular produced by laser cutting are. This significantly reduces the cost of manufacturing the press beam or the lower press beam section.
  • the pressing beam is arranged in particular on its side facing the cutting plane at a minimum distance from the cutting plane. This ensures that the material to be cut can be pressed almost to the cutting plane by means of the press beam.
  • a minimum distance is preferably understood to mean a distance of the press beam to the cutting plane of 0.2 to 0.6 mm, in particular 0.3 to 0.5 mm.
  • the elastic element extends on its side facing the cutting plane to the side of the press beam facing the cutting plane in the region of its underside.
  • This arrangement is achieved, for example, in that when the elastic element is attached to the pressing beam, the elastic element is positioned on its side facing the cutting plane beyond the cutting plane.
  • the region of the elastic element projecting beyond the cutting plane is cut off. Based on this pressed state of the elastic element this thus extends on its side facing the cutting plane to the cutting plane. In the subsequent cut is thus no longer cut into the elastic element.
  • the elastic element is formed relatively thin-walled. This is preferably understood as meaning a wall thickness of 2 to 4 mm, in particular of 2 to 3 mm.
  • the elastic element based on the non-lowered position of the press beam, thus the uncompressed position of the elastic element, on its side facing away from the cutting plane up to 10 mm, in particular 3 to 6 mm on the press bar over.
  • the elastic element can also be designed in such a way that, in addition to the projection on the side facing away from the cutting plane of the press beam over one or all, thus both of the arranged perpendicular to the cutting plane sides of the press beam or lower pressing beam portion. As a rule, such a supernatant will not be required because the pressing beam has a greater extension in the direction of the cutting plane than is the maximum extent of the material to be cut in this direction.
  • the elastic element is made of rubber or substantially of rubber. It thus has an excellent elasticity in order to fulfill the purpose of the invention.
  • blanket used in a printing roll of a printing press is used for the elastic member of the cutting machine. It is only necessary to cut and apply this blanket according to the dimensions of the press beam in the area of the underside.
  • the elastic element is provided on its side facing the pressing beam with an adhesive layer. This makes it possible to easily and quickly attach the elastic element to the pressing beam.
  • the pressing beam has a lower pressing beam section, in particular a pressing beam section designed as a plate, to which the elastic element is connected.
  • this lower press beam section is a separate part which is detachably connected to an upper main area of the press beam.
  • Such a separate press beam section makes it possible, on the one hand, for the press beam to be exactly with respect to a complementary design of the feed device form, on the other hand, the elastic element ergonomic and easy to attach to the pressing beam section.
  • the press beam or the lower press beam section is rectangular or comb-shaped in the contact region to the elastic element, the teeth of the comb being directed away from the cutting plane.
