Definitions

  • the present invention relates to a distribution device for a facing material or generally flowable material for use in a slab production plant.
  • a facing material or generally flowable material for use in a slab production plant.
  • Such slab production plants and facing distribution devices are known from the prior art.
  • the term facing refers to the material which is later pressed together with backing concrete to form a slab.
  • the attachment distribution device serves to distribute the attachment material introduced into a mold, in particular by means of distribution devices within a mold. For example, servo motors with absolute value encoder devices can be used.
  • CN 107 650 246 A In the documents CN 107 650 246 A , EP 1 767 320 A1 and CN 108 214 852 A Distribution devices are already presented which distribute a facing material by inserting pin-like elements into the facing material and moving these elements.

  • GB 906 542 A A system is shown in which a facing material is distributed by inserting a flat surface into the receiving container with the facing material.
  • Such forms include slab shapes, such as terrazzo and concrete stone slabs, hermetic-quality paving stones, terrace and pavement slabs or single-layer and double-layer plates, manufactured using combined filter and hermetic press processes.
  • Such panels are pressed within molds using a hermetic pressing process, with typical pressing pressures ranging between 4 and 24 N/mm 2.
  • typical panel product thicknesses range between 8 and 140 mm.
  • the material may not be distributed sufficiently. If the immersion depth is too great, this may result in material being forced out of the mold.
  • the present invention is therefore based on the object of providing a plate production plant with a pre-distribution device which, in the case of such a hermetic press, enables a pre-distribution with different parameters, in particular a different penetration depth of the distribution device.
  • the front distributor device is adjustable by means of an adjusting device, wherein this adjusting device has a drive device.
  • an automated setting of the penetration depth of an attachment distributor device of the plate production system within a mold is therefore proposed.
  • an attachment distributor device can be provided which has an arm which is arranged above a mold.
  • the mold can also be arranged below the attachment distributor device.
  • the attachment distributor device is preferably arranged above the receiving container, at least in a working mode.
  • the actuating device particularly preferably has a drive device in the form of an electric drive, in particular a linear motor drive, a pneumatic drive, a hydraulic drive and/or the like.
  • the distribution body is advantageously movable between two end positions. One position can be a position in which the distribution body is at least partially immersed in the flowable material. The second position can be an upper position, in particular a position in which the distribution body is spaced apart from the flowable material.
  • the receiving container can be moved relative to the front distributor device in a transport direction that deviates from the immersion direction.
  • This transport direction preferably runs perpendicular or essentially perpendicular to the immersion direction.
  • Essentially perpendicular is understood to mean a deviation of less than 10°, preferably less than 5°, from the perpendicular direction.
  • the receiving container can particularly preferably be moved along a circular path.
  • the receiving container is arranged on a movable and in particular rotatable carrier.
  • the adjusting device is an automatic adjusting device.
  • the immersion depth can be controlled via a computer program It is also possible for an operator to enter the corresponding immersion depth. It is also possible for the stroke or the immersion depth to depend on a measured value, for example on the thickness of a plate to be pressed, and/or to be set depending on this plate thickness.
  • a lifting cylinder can be provided that is itself movable relative to a stationary sleeve body.
  • the immersion depth of the front distributor device is adjustable and in particular automatically adjustable.
  • a further drive device for example a servo motor and/or an absolute encoder device, can be present for adjustment.

  • an element that carries out the lifting movement can be provided that strikes this stop so that the movements in this position are hindered or stopped. This means that the element that moves to the stop is changed in position, so that the stroke is changed as a result.
  • the position of this stop can be changed by the adjusting device.
  • the stop itself is carried along or moved along with the lifting movement.
  • the distributor device has a guide device for guiding the movement in the immersion direction.
