Abstract

Process for making and/or handling concrete blocks which are produced in moulds filled with concrete and are embossed on their surface by means of punches which have recesses or projections. The surface of the concrete blocks is subsequently roughened, shaped or textured and freed of loose parts by brushes, in particular strip brushes or roller brushes. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren zum Herstel­len und/oder Behandeln von Betonsteinen, insbesondere Pflastersteinen, wobei die Herstellung in mit Beton ge­füllten Formen und der Form bzw. der Steinoberfläche ent­sprechenden Stempeln zum Prägen der Oberfläche und Sicht­kanten erfolgt, wobei die Stempel Ausnehmungen bzw. Vor­sprünge aufweisen und wobei in einem nachgeschalteten Ar­beitsgang die Oberflächen bzw. Kanten der Betonsteine mit Bürsten bearbeitet werden.The invention relates to a method for producing and / or treating concrete blocks, in particular paving stones, the production taking place in molds filled with concrete and stamps corresponding to the shape or the stone surface for embossing the surface and visible edges, the stamps being recesses or Have projections and the surfaces or edges of the concrete blocks are processed with brushes in a subsequent operation.

In der älteren Patentanmeldung werden mehrere verschieden­artige Verfahrensschritte, u.a. auch Bürsten vorgeschla­gen, um in dem nachgeschalteten Arbeitsgang die Oberfläche bzw. Kanten der Betonsteine von losen Teilen zu befreien und/oder zusätzlich aufzurauhen, zu formen bzw. zu struk­turieren.In the earlier patent application, several different process steps, including brushes have also been proposed in order to free the surface or edges of the concrete blocks from loose parts and / or to additionally roughen, shape or structure them in the subsequent operation.

Aufgabe der vorliegenden Erfindung ist es, diesen nachge­schalteten Arbeitsgang weiter auszubilden und insbesondere einfache und praxisgerechte aber wirkungsvolle Bürstenaus­gestaltungen bzw. -anordnungen vorzustellen. Gelöst wird die Aufgabe der Erfindung dadurch, daß die Bürsten eine oszillierende Bewegung parallel zur Oberfläche der Beton­steine ausführen. Durch diese oszillierende Bewegung strei­chen die Bürsten nicht nur in einer Richtung über die Steine sondern in entgegengesetzten Richtungen hin und her, so daß eine sehr vorteilhafte Nachbearbeitung der Oberflächen bzw. Kanten der Betonsteine erfolgt. Der Hub der oszillierenden Bewegung kann dabei variiert bzw. ein­gestellt werden, so daß auf der Oberfläche der Betonsteine eine Hubumkehrung mit entsprechendem Umknicken der Borsten der Bürsten erfolgt. Von wesentlicher Bedeutung ist, daß die Steine noch nicht ausgehärtet, d.h. in frischem Zustand oder nur leicht angetrocknet bzw. angehärtet sind, damit eine optimale Bearbeitung erfolgen kann.The object of the present invention is to further develop this downstream work step and in particular to present simple and practical but effective brush designs and arrangements. The object of the invention is achieved in that the brushes a Carry out oscillating movement parallel to the surface of the concrete blocks. By means of this oscillating movement, the brushes sweep back and forth not only in one direction over the stones, but in opposite directions, so that the surfaces or edges of the concrete blocks are reworked very advantageously. The stroke of the oscillating movement can be varied or adjusted so that a stroke reversal takes place on the surface of the concrete blocks with a corresponding bending of the bristles of the brushes. It is essential that the stones have not yet hardened, ie are fresh or only slightly dried or hardened, so that optimal processing can take place.

In weiterer Ausgestaltung der Erfindung wird vorgeschla­gen, daß die oszillierende Bewegungsrichtung der Bürsten unter einem spitzen Winkel zur Bewegungsrichtung der Be­tonsteine erfolgt, so daß auch alle Kanten der Betonsteine gleichmäßig bearbeitet werden. In vorteilhafter Weise sind die Bürsten als Streifenbürste ausgebildet, deren Länge einer Vielzahl von Betonsteinabmessungen entspricht. Da­durch läßt sich das Bürsten-Bearbeitungsverfahren in vor­teilhafter Weise räumlich und zeitlich unmittelbar an das Prägen der Betonsteine anschließen, zumal bei dem Prägen vorzugsweise gleichzeitig eine Vielzahl von Betonsteinen herstellt werden, die auf einer Palette die Maschine in einer Bewegungsrichtung verlassen. In vorteilhafter Weise wird daher durch die Streifenbürste eine Vielzahl von Be­tonsteinen gleichzeitig bearbeitet. Es können auch mehrere Streifenbürsten vorgesehen sein, die z.B. versetzt zuein­ander angeordnet sind.In a further embodiment of the invention it is proposed that the oscillating direction of movement of the brushes takes place at an acute angle to the direction of movement of the concrete blocks, so that all edges of the concrete blocks are machined evenly. The brushes are advantageously designed as a strip brush, the length of which corresponds to a large number of concrete block dimensions. As a result, the brush processing method can advantageously be connected in space and time directly to the embossing of the concrete blocks, especially since a large number of concrete blocks which leave the machine in one direction of movement on a pallet are preferably produced simultaneously during the embossing. A large number of concrete blocks are therefore advantageously processed simultaneously by the strip brush. A plurality of strip brushes can also be provided, which are arranged, for example, offset from one another.

Es hat sich als vorteilhaft erwiesen, mehrere auch ver­schiedenartige Bürsten hintereinander anzuordnen, so daß die Betonsteinoberflächen mehrfach bearbeitet werden.It has proven to be advantageous to arrange several brushes of different types one behind the other so that the concrete block surfaces are machined several times.

Zur weiteren Erläuterung der Erfindung wird auf die Zeich­nungen verwiesen, in denen mehrere Ausführungsbeispiele der Erfindung vereinfacht dargestellt sind. Es zeigen:

  • Fig. 1 eine Draufsicht auf eine Vielzahl von Betonsteinen mit einer darüber angeordneten Streifenbürste;
  • Fig. 2 eine Seitenansicht der Betonsteine und einer Strei­fenbürste und
  • Fig. 3 eine Draufsicht mit oberhalb der Betonsteine ange­ordneten Streifen- und Walzenbürste.
To further explain the invention, reference is made to the drawings in which several exemplary embodiments of the invention are shown in simplified form. Show it:
  • Figure 1 is a plan view of a plurality of concrete blocks with a strip brush arranged above.
  • Fig. 2 is a side view of the concrete blocks and a strip brush and
  • Fig. 3 is a plan view with strip and roller brush arranged above the concrete blocks.

In den Figuren 1 bis 3 sind, soweit im einzelnen darge­stellt, mit 3 Betonsteine bezeichnet, die, ersichtlich in Fig. 2, auf einer Unterlage bzw. Palette 4 angeordnet sind, die gemäß Pfeil 5 bewegt wird. Oberhalb der Beton­steine 3 ist eine mit 6 bezeichnete Streifenbürste ange­ordnet, die an Ständern 7 derart gelagert ist, daß sie ge­mäß dem Doppelpfeil 8 oszillierend hin- und herbewegt wer­den kann. Die oszillierende Bewegung in Richtung des Doppelpfeils 8 wird durch einen an einem der Ständer ange­ordneten Antrieb 9 erzeugt.In Figures 1 to 3, as far as shown in detail, 3 concrete blocks are designated, which, as shown in Fig. 2, are arranged on a base or pallet 4, which is moved according to arrow 5. Above the concrete blocks 3 there is a strip brush, designated 6, which is mounted on stands 7 in such a way that it can be moved back and forth in accordance with the double arrow 8. The oscillating movement in the direction of the double arrow 8 is generated by a drive 9 arranged on one of the stands.

Fig. 3 zeigt ein Ausführungsbeispiel, bei dem zusätzlich zu der Streifenbürste 6 eine Walzenbürste 10 vorgesehen ist. Die Walzenbürste 10 ist in Ständern 7a drehbar gela­gert. Durch sie wird eine Nachbearbeitung der Betonsteine bzw. deren Oberflächen und Kanten erzeugt.Fig. 3 shows an embodiment in which a roller brush 10 is provided in addition to the strip brush 6. The roller brush 10 is rotatably supported in stands 7a. They are used to post-process the concrete blocks or their surfaces and edges.

Die Ständer können so auf dem Boden verschoben werden, daß eine optimale Winkellage der Streifen- und der Bürstenwal­ze eingestellt werden kann. Weiterhin sind die Streifen­bürste 6 und Walzenbürste 10 an den Ständern in der Höhe verstellbar, so daß auch deren Intensität variiert werden kann. Wie bereits in dem allgemeinen Beschreibungsteil an­gesprochen wurde, kann auch der Hub der oszillierenden Be­wegung der Streifenbürste 6 und die Hubgeschwindigkeit so­wie die Drehzahl der Wälzenbürste variiert werden, so daß der gewünschte Bearbeitungseffekt eintritt.The stand can be moved on the floor so that an optimal angular position of the strip and brush roller can be set. Furthermore, the strip brush 6 and roller brush 10 are adjustable in height on the stands, so that their intensity can also be varied. As already mentioned in the general description part, the stroke of the oscillating movement of the strip brush 6 and the stroke speed as well as the speed of the roller brush can be varied so that the desired machining effect occurs.
