Definitions

  • the invention relates to a device for receiving plate-shaped materials for at least one separation process in the plate-shaped material with a cutting jet device of a processing machine.
  • a processing machine which is designed in particular as a laser processing machine and comprises a first and second support surface for receiving a plate-shaped material for a separation process in the plate-shaped material. These first and second bearing surfaces form a common support table. Between the first and second support surface, a line-shaped beam-catching device is provided, which can be moved in the X-direction. An opening of the beam-catching device below of the plate-shaped material is associated with the cutting beam of the movable cutting device, extends in the ⁇ -direction.
  • the first and second support surface is formed, for example, by a support belt, which is lowered in the process of the beam-catching device relative to the support plane down.
  • This support belt is designed as a brush strip which extends in the Y direction across the width of the support table and is held on both sides by a link chain.
  • the beam catcher is coupled to a link which engages the link chain. When moving the beam-catching device, the brush strips are lowered accordingly. The beam-catching device thus remains embedded between the first and second support surface.
  • the invention has for its object to provide a structurally simple design, which allows a deflection of the support belt to the beam-catching device and at the same time a continuous support of resting on the first and second support surface plate-shaped material.
  • An apparatus according to the preamble of claim 1 is known from FR 2 631 878-A1 known.
  • a structurally simple design of a support device is made to hold the at least one support belt in a support plane of the first and second support surface of the support table.
  • the support device which consists of a plurality of support elements and acts on the outer edge region of the at least one support belt, has the advantage that the support table can be assembled from two or more mutually parallel support belts. As a result, a longitudinally divided support or a longitudinally divided support table with a plurality of support belts can be achieved.
  • This division of the support table in longitudinal strips has the advantage that a cantilevered route over the entire width of a support table can be divided into several short sections, whereby a reduction of a roller deflection of pulleys is made possible. At the same time can be achieved by reducing the diameter of the pulleys, a weight saving and a reduction of the required space and a compaction of the construction.
  • the at least one support belt in each case with its outer edge region, rests on a support surface, in particular end-side support surface, of the support elements.
  • the support elements have a rod-shaped body, which is received in a guide device movable up and down. By this rod-shaped body can be provided against rotation in the guide device.
  • the guide device for receiving the support elements extends according to a preferred embodiment in the direction of travel of the beam-catching device, ie in the X direction, and comprises two mutually parallel and spaced-apart support, between which the support elements are guided adjustable in height.
  • a structurally simple configured support device may be formed with support elements and a guide device.

  • This at least one slider or guide body made possible by a low-friction receiving and guiding the at least one support element of the support device a low-friction lifting movement of the support elements.
  • the support elements of the support device are held according to a preferred embodiment of the invention in an upper end position by a Endlagenfix ist. Characterized in that a plurality of support elements are arranged along the edge region of the at least one support belt, a relatively small holding force is sufficient for positioning the individual support element in the upper end position. In addition, the positioning of the support element by a holding force in the upper end position has the advantage that a quasi force-free movement of the support elements is made possible outside the end position.
  • the end position fixation is designed as a holding force for positioning the support elements in an upper end position as a magnetic force.
  • This can be given in particular a wear-free arrangement.
  • the magnetic holding force as end position fixation acts only in the upper end position. In a remaining position of the support element, this holding force is ineffective.
  • the holding force may alternatively be designed as a clamping force, friction force, clamping force, latching force or locking force.
  • an end position fixing for positioning an upper end position is provided away from the support surface of the support element and cooperates with the carrier.
  • a large movement space or a holding force-free lifting movement of the support element can be created.
  • a sufficiently large space for the beam-catching device and the pulleys is given to allow a deflection and underside passage of the at least one support belt to the beam-catching device.
  • a stop is provided at the lower end of the support element, which limits a lifting movement in the end position.
  • the upper region of the support elements can be formed with a small installation space, so that the distances between two adjoining support strips can be kept small.
  • the support elements or the carrier have a holding magnet which positions the support element in the end position on the carrier.
  • These holding magnets are preferably fixed by an adhesive or clamping connection or with a pocket-shaped receptacle on the support element or the carrier and allow a structurally simple arrangement and design.
  • the guiding device preferably accommodates a plurality of supporting elements which are arranged next to one another and whose end faces rest against one another. As a result, complete support can take place along the edge region of the support belts, which also achieves that the support force of each individual support element is reduced. As a result, the holding force can be reduced, which in turn results in a compact construction.
  • the adjacent end faces of the support elements, which are received by the guide device, preferably each have a guide profile, so that the adjacent guide profiles interlock. This in turn is given a guide of the support elements in the Y direction. On the one hand, the lifting movement of the one support element and the adjacent support element is guided and controlled. On the other hand, a stiffening of the successive supporting elements in the Y direction is given at the same time.
  • a drive element is preferably provided which can be actuated through the backdrop.

The changes in the volume, in particular the length of the support elements due to a thermal expansion in the X direction can be compensated, so that at a changing temperature constant working conditions are given and jamming or distortion of the individual support elements is prevented due to thermal expansion.
  • the thermal expansion compensation device preferably has a fixed stop at one end of the carrier and a stop which can be displaced in the X direction at the opposite end of the same carrier. This makes it possible that the displaceable stop acts on the support elements and is held displaceably in the X direction upon thermal expansion of the support elements. The uniquely set basic game of support elements is thereby maintained.
  • the thermal expansion compensation device comprises a strip, which is arranged a pointing to the lower end of the support member portion of the support and has a substantially corresponding to the support elements thermal expansion coefficient and preferably each receives a holding magnet of the respective support member opposite metal plate.
  • the sliding is arranged on the carrier, it is now possible that the support elements remain freely movable relative to each other, since the bar experiences the same thermal expansion as the support elements as a stop element.
  • the displaceable stop is coupled to the strip, so that this stop is moved by the strip both in and against the X direction due to the same or the same coefficient of thermal expansion as the support elements.
  • a further preferred embodiment of the invention provides that at least one thermal expansion compensation device acting in the Z direction is provided on the guide device. This ensures that a defined holding position of the support element for receiving the support belt is achieved. As a result, it is also possible at the same time for a safe movement of the support elements from this holding position into a lowered position to be made possible by the activation elements on the support element securely engaging in the slotted link for lowering the support elements.
  • the thermal expansion compensation device acting in the Z direction preferably has at least one rod element pointing in the Z direction, in particular aligned parallel to the support element, which abuts a preferably adjustable stop on.

  • the at least one support belt is formed as a brush segment belt.
  • Such brush segment bands comprise a plurality of preferably mutually parallel strips which are stiffened in the Y direction and flexible in the X direction due to flexible and zuglastbaren connecting elements to allow a deflection around the beam-catching device.
  • Such brush segment bands have the advantage that a gratolerante support for the plate-shaped material is made possible, that is, that on the underside of the plate-shaped material during the separation process, if necessary, burrs do not affect the flat support of the plate-shaped material.
