Definitions

  • the geometry of the suction heads for cutting out, vacuuming and depositing is adapted to the brick model to be produced and connected to the machine via a carrying unit.
  • a vacuum is applied to the suction head to suck and hold the molding. It is deposited using a pneumatic cylinder moving plate and additional compressed air ejection nozzles.
  • the suction heads have appropriate media connections for this.
  • the suction heads and their knives are subject to a certain amount of wear due to regular contact with the clay material. Wear of the knives affects the surface of the cut. The cut must be as smooth as possible. For this reason and also because of the individual design for each brick model, there is a need to change the suction heads at regular intervals or to remove them for maintenance purposes.
  • the suction heads are separably connected to their support units.
  • a mounting plate or an adapter plate are attached to the support units and the suction heads.
  • the adapter plate is always on top of the suction heads. The suction head therefore hangs on the respective support unit or on its separate mounting plate, with the cutting edge of the knife frame pointing downward.
  • the zero point clamping system is preferably designed and used in the operating method to ensure that the clamping unit during Locking process grips the clamping bolt within the axial gripping tolerance and then axially fixed while canceling the axial gripping tolerance.
  • the clamping unit during Locking process grips the clamping bolt within the axial gripping tolerance and then axially fixed while canceling the axial gripping tolerance.
  • the drum and thus also the lower mold 6 arranged on the side surface is then rotated further about the longitudinal axis 90 by the angle of rotation.
  • the angle of rotation is 60 °.
  • the lower mold 6 and the movement device 5 return to their initial state. In the exemplary embodiment, this happens after six rotations.
  • Fig. 3 shows a perspective front view of the roof tile press according to the 1 and 2 in the area of the removal point 8.
  • the roof tile press 1 has the same number, here four suction head devices 60.
  • the suction head device 60 By means of the suction head device 60, the pressed moldings 22 are reworked in the working step Fig. 2 taken from their respective lower mold 6, trimmed in their contours and according to Fig. 3 stored on shaped carriers 20.
  • the molding carriers 20 are in turn located on a conveyor 16, by means of which the molding carriers 20 and the moldings 22 placed thereon are transported away and fed for further processing.
  • tensioning bolts 64 thread themselves into the receiving openings of the associated tensioning units 65 in accordance with Fig. 6 a.
  • a combined movement of the two assemblies is also conceivable within the scope of the invention.
  • the clamping bolts 64 and the clamping unit 65 are also coordinated with one another in such a way that they have an axial gripping tolerance a against one another during the locking process.
  • Fig. 6 shown that the approach of the suction head 24 and the support unit 61 in the z-direction has been advanced so far that the desired target position is almost reached within the framework of a machine-controlled rough positioning, but that there is still a gap between the suction head 24 and the support unit 61.
  • the clamping bolt 64 is not fully inserted into the clamping unit 65, so there is no stop between the suction head 24 and the carrying unit 61 in the context of the rough positioning mentioned.
  • the mentioned gap corresponds to the axial gripping tolerance a measured in the z direction, within which, on the one hand, there remains a residual mobility of the suction head 24 relative to the support unit 61 in the z direction, but on the other hand also the zero point clamping system 63 can be reliably locked.
  • the axial gripping tolerance is preferably at least one millimeter and is in particular in the range from one to three millimeters. In the preferred exemplary embodiment shown, it is approximately two millimeters.
