Definitions

  • the invention relates to a device for producing concrete blocks according to the preamble of claim 1.
  • the invention also relates to a storage container having a receiving space for a plurality of layers of different colored concrete for use in a device for producing concrete blocks according to claim 11.
  • the invention further relates to a method for producing concrete blocks according to the preamble of claim 12.
  • a generic device and a generic method is from the EP 1 017 554 B1 known.
  • Conventional methods for producing concrete blocks usually provide a basic body formed from coarse concrete, which is provided on the top with a fixed covering layer of colored concrete or concrete mortar. It is provided that the rough concrete is filled into a mold and compacted by shaking and / or pressing in the mold. This lowers the coarse concrete. In the lowered space of the mold from a storage container, which is also referred to as header tank or header silo, applied the colored concrete mortar on the rough concrete as a facing layer and compacted.
  • a storage container which forms a receiving space for a plurality of layers of different colored concrete, wherein the bottom of the storage space is designed as a slide.
  • the slide is opened continuously or intermittently, so that fall due to gravity subsets or portions of the layers down and fed to a downstream dispenser.
  • the downstream dispensing device may have a closure member, which is designed to control a quantitative, portionwise dispensing of the colored concrete or concrete mortar and filled the molds.
  • the configuration of the reservoir with a slide only causes a relatively low mechanical complexity and leads to improved mixing of the layers of different colored Concrete. Nevertheless, the mixing of layers of different colored concrete is still not cheap enough; In particular, heaps continue to occur. This is especially true for the first subset, which falls down when opening the slider. In this only a small or insufficient mixing takes place.
  • the EP 1 017 554 B1 proposed that the slider known from practice is combined with baffles which are arranged in the path of movement of the downwardly moving parts of the concrete layers.
  • the subsections of the concrete layers are intended to impinge on the impact bodies in such a way that the subsections are guided onto a deflection arc and are better mixed with one another.
  • the present invention is therefore an object of the invention to provide an apparatus and a method for producing concrete blocks, which allow it with little effort, several Mix layers of different colored concrete in the desired manner with each other, in particular to produce facing layers with a defined, similar appearance for concrete blocks.

  • the topmost layer associated dispensing opening is opened in the side wall and then - with a time delay - subsets of underlying or underlying layers are output through the dispensing opening.
  • subsets of the different layers of colored concrete arrive at the same time at the end of their movement or trajectory and thereby sets a desired, for example, uniform mixing.
  • Achieving a temporally offset opening can be achieved for example by an oblique to the discharge opening arrangement of the output means or an oblique arrangement of the opening edge of the output means.
  • any mixing can be set with the device according to the invention and the method according to the invention. It is essential that, in particular, the mixing ratio of the first subset of the concrete removed from the receiving space of the storage container is no longer dependent on first draining the layer next to the bottom of the storage container.
  • the output means open and close the dispensing opening in cycles, in order to dispense a subset of the layers during the opening cycle. This makes it possible in each case to discharge a defined amount of concrete from the individual layers.

  • This overhang when the at least one dispensing opening is opened by the dispensing means, may fall down independently of the underlying layer due to gravity.
  • further concrete can slip and be dispensed with through the dispensing opening. If appropriate, provision may be made for the dispensing means to open the dispensing opening only for a defined time and then close it again. In another opening cycle thus the slipped concrete can be output defined.

These values have been found to be particularly suitable in terms of the desired uniform mixing and in consideration of the desired subset, which is to be output through the discharge opening in the side wall.
  • the receiving space or the reservoir in the direction of the at least one output port provided side wall is tiltable or pivotable or tiltable.
