Description

Vorrichtung zum Herstellen eines Hohlbausteins aus einer hydraulisch aushärtenden, feuchten BausteinmasseDevice for producing a hollow component from a hydraulically hardening, moist building block mass
Technisches GebietTechnical area
Die Erfindung bezieht sich auf eine Vorrichtung zum Herstellen eines Hohlbau¬ steins aus einer hydraulisch aushärtenden, feuchten Bausteinmasse mit einer nach oben offenen Form, die innerhalb von Formwänden von einem Formbo¬ den aufragende, mit seitlichem Abstand voneinander angeordnete Kernstege zur Ausbildung von Hohlkammern des Hohlbausteins umfaßt, und mit einem entlang einer Führung über die Form fahrbaren Füllwagen, der einen durch Umfangswände begrenzten Aufnahmeraum mit einem Siebboden zum Aus¬ bringen der aufgenommenen Bausteinmasse bildet.The invention relates to an apparatus for producing a Hohlbau¬ stone from a hydraulically curing, wet building block mass with an upwardly open mold, the upstanding inside mold walls of a Formbo¬, spaced laterally spaced core webs to form hollow chambers of the hollow block comprises, and with a movable along a guide over the form of filling carton, which forms a limited by peripheral walls receiving space with a sieve bottom for Aus¬ bring the recorded building block mass.
Stand der TechnikState of the art
Zum Herstellen von Hohlbausteinen mit einer Mehrzahl von Hohlkammern aus einer hydraulisch aushärtenden Bausteinmasse ist es bekannt (EP 0 706 864 A2), eine Form mit einem Formboden vorzusehen, auf den ein die Formwände bildender Formkasten aufgesetzt wird und durch den von unten Kernstege in den vom Formkasten umschlossenen Formraum zur Ausbildung der Hohlkam¬ mern eingreifen. Mit Hilfe eines entlang einer Führung über die Form verfahrba¬ ren Füllwagens wird die Form mit der angefeuchteten Bausteinmasse befüllt, bevor die in die Form eingefüllte Bausteinmasse mit Hilfe einer Preßplatte verdichtet wird, die entsprechende Durchtrittsöffnungen zur Aufnahme der vom Formboden aufragenden Kernstege aufweist. Zum Entformen des in dieser Weise hergestellten Hohlbausteins werden die Kernstege durch den Formbo¬ den aus dem Formraum nach unten zurückgezogen und der Formkasten vom Formboden abgehoben.For the manufacture of hollow blocks with a plurality of hollow chambers made of a hydraulically curing building block mass, it is known (EP 0 706 864 A2) to provide a mold with a mold bottom, on which a mold box forming mold box is placed and by the core webs from below in the from Form box enclosed mold space to form the Hohlkam¬ mers intervene. The mold is filled with the moistened building block mass by means of a filling carriage movable along a guide over the mold before the building block mass filled into the mold is compacted by means of a pressing plate which has corresponding passage openings for receiving the core webs projecting from the mold bottom. To demould the in this Made hollow block, the core webs are withdrawn by the Formbo¬ from the mold cavity down and lifted the mold box from the mold bottom.
Um eine gleichmäßige Verdichtung der feuchten Bausteinmasse in der Form und damit über den Querschnitt gleiche mechanische Eigenschaften des Hohl¬ bausteins zu erreichen, ist eine über den Querschnitt gleichmäßige Befüllung der Form mit der feuchten Bausteinmasse vorauszusetzen, was jedoch mit Hilfe der herkömmlichen Füllwagen nicht sichergestellt werden kann. Dies liegt einerseits an der Neigung der feuchten Bausteinmasse zur Verklumpung und anderseits daran, daß über den Querschnitt der Bodenöffnung des Füllwagens keine gleichmäßige Ausbringung der Bausteinmasse gewährleistet werden kann. Dazu kommt, daß die Ausbringungsmenge an Bausteinmasse von der Geschwindigkeit abhängt, mit der der Füllwagen über die Form bewegt wird. Wird zum Auflockern der ausgebrachten Bausteinmasse der Füllwagen mit einem Siebboden versehen, so können die auftretenden Ungleichmäßigkeiten verringert nicht aber vermieden werden.In order to achieve a uniform compaction of the wet building block mass in the mold and thus over the cross section the same mechanical properties of the Hohl¬ building block, a uniform over the cross section filling the mold with the wet building block mass is assumed, but this can not be ensured with the help of conventional filling can. This is due on the one hand to the tendency of the wet building block mass to agglomerate and on the other hand because over the cross section of the bottom opening of the filling carriage no uniform application of the building block mass can be guaranteed. In addition, the output quantity of block mass depends on the speed with which the filling carriage is moved over the mold. If, for the purposes of loosening the applied building block mass, the filling car is provided with a sieve bottom, the irregularities which occur can not be reduced, but can not be avoided.
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt somit die Aufgabe zugrunde, eine Vorrichtung zum Herstel¬ len eines Hohlbausteins der eingangs geschilderten Arts so auszugestalten, daß eine gleichmäßige Befüllung der Form mit feuchter Bausteinmasse als Voraussetzung für über den Querschnitt gleichbleibende mechanische Eigen¬ schaften des herzustellenden Hohlbausteins sichergestellt werden kann.The invention is thus based on the object, a device for len len manufacture of a hollow brick of the above-described Arts so that a uniform filling of the mold with moist building block mass as a prerequisite for over the cross-section consistent mechanical properties Eigen¬ properties of the hollow block to be produced can be ensured.
Die Erfindung löst die gestellte Aufgabe dadurch, daß der im Füllwagen schwingungsfähig gelagerte Siebboden an einem Schwingungsantrieb ange¬ schlossen ist und unterschiedlich große Sieböffnungen mit einem einen freien Durchtritt der feuchten Bausteinmasse zufolge ihres Eigengewichtes unterbin¬ denden Öffnungsquerschnitt in einer vom Verlauf der Umfangswände des Aufnahmeraums und/oder der Formwände und der Anordnung der Kernstege abhängigen Verteilung über den Formquerschnitt aufweist und daß der Füllwa¬ gen in einer anschlagbegrenzten Füllstellung über der Form verriegelbar ist.The invention solves this problem by the fact that the sieve bottom vibrationally mounted in a vibratory drive ange¬ is closed and different sized sieve openings with a free passage of the wet building block mass according to their own weight interrupting opening cross-section in one of the course of the peripheral walls of the receiving space and / or the mold walls and the arrangement of the core webs has dependent distribution over the shape of the cross-section and that the Füllwa¬ gene is locked in a stop-limited filling position on the mold.
Die Erfindung geht von der Erkenntnis aus, daß sich aufgrund der inneren Reibung der feuchten Bausteinmasse und der Reibung zwischen der Bau¬ steinmasse und der Reibung zwischen der Bausteinmasse und den Umfangs- wänden des Aufnahmeraums über die Siebfläche ungleichmäßige Ausbrin¬ gungsbedingungen ergeben. Aus diesem Grunde wird zum Ausgleich dieser Ungleichmäßigkeiten der Siebboden mit unterschiedlich großen Sieböffnungen versehen. Mit diesen unterschiedlich großen Sieböffnungen lassen sich aber nicht nur die ungleichmäßigen Ausgleichsbedingungen der Bausteinmasse aus dem Aufnahmeraum des Füllwagens, sondern auch ungleichmäßige Füllbedin¬ gungen im Bereich der Form berücksichtigen, indem die Verteilung der unter¬ schiedlich großen Sieböffnungen über den Formquerschnitt in Abhängigkeit vom Verlauf der Umfangswände des Aufnahmeraums und der Formwände und der Anordnung der Kernstege der Form gewählt wird. Dies bedeutet jedoch, daß für die Füllung der Form mit der Bausteinmasse der Füllwagen eine vorge¬ gebene Füllstellung gegenüber der Form einnehmen muß. Außerdem darf die Befüllung der Form erst in der Füllstellung des Füllwagens vorgenommen werden. Diese Forderungen werden einerseits durch eine Verriegelung des Füllwagens in der anschlagbegrenzten Füllstellung und anderseits dadurch erfüllt, daß die unterschiedlichen Sieböffnungen einen Öffnungsquerschnitt aufweisen, der ein freies Durchtreten der feuchten Bausteinmasse zufolge ihres Eigengewichtes unterbindet. Zum Ausbringen der feuchten Baustein¬ masse ist der Siebboden mit Hilfe eines Schwingungsantriebes einer Rüttelbe¬ wegung zu unterwerfen, die für den Durchtritt der Bausteinmasse durch die Sieböffnungen sorgt. Der Siebboden ist folglich schwingungsfähig im Füllwa¬ gen zu lagern.The invention is based on the finding that non-uniform application conditions result due to the internal friction of the wet building block mass and the friction between the building stone mass and the friction between the building block mass and the peripheral walls of the receiving space. For this reason, to compensate for these irregularities of the sieve plate is provided with different sized sieve openings. With these differently sized screen openings, however, not only the uneven compensation conditions of the block mass from the receiving space of the charge truck but also uneven filling conditions in the area of the shape can be taken into account by the distribution of the differently sized screen openings over the shape cross section as a function of the course of the Peripheral walls of the receiving space and the mold walls and the arrangement of the core webs of the mold is selected. However, this means that for the filling of the mold with the building block mass of the filling carriage must occupy a vorge¬ given filling position relative to the mold. In addition, the filling of the mold may only be made in the filling position of the filling carriage. These requirements are met on the one hand by a locking of the filling carriage in the stop-limited filling position and on the other hand, that the different screen openings have an opening cross-section, which prevents free passage of the wet building block mass according to their own weight. In order to dispense the moist building block mass, the sieve bottom is to be subjected to a vibration movement by means of a vibration drive, which ensures the passage of the building block mass through the sieve openings. The sieve bottom is therefore capable of vibrating in Füllwa¬ gene to store.
Obwohl für die Schwingungsanregung des Siebbodens unterschiedliche Kon¬ struktionen eingesetzt werden können, ergeben sich besonders einfache Kon¬ struktionsverhältnisse, wenn der Siebboden in einer Verschiebeführung des Füllwagens gelagert und an einen Exzentertrieb als Schwingungsantrieb ange- schlössen wird. Über die Exzentrizität und/oder die Umlaufgeschwindigkeit des Exzentertriebes lassen sich außerdem die Schwingweiten und die Schwin¬ gungsfrequenzen an die jeweiligen Anforderungen hinsichtlich der eingesetzten Bausteinmasse anpassen.Although different designs can be used for exciting the vibration of the sieve tray, particularly simple construction conditions result if the sieve tray is mounted in a displacement guide of the filling carriage and attached to an eccentric drive as vibration drive. will conclude. By means of the eccentricity and / or the rotational speed of the eccentric drive, it is also possible to adapt the oscillation ranges and the oscillation frequencies to the respective requirements with regard to the module mass used.
Wegen der Schwingungsanregung des Siebbodens kann eine Verstopfungsge¬ fahr weitgehend ausgeschlossen werden. Es können daher unterschiedliche Siebböden zum Einsatz kommen. Besonders günstige Ausbringungsverhältnis¬ se ergeben sich jedoch, wenn der Siebboden aus einem Gitterrost besteht. Die Stäbe dieses Gitterrostes können darüber hinaus unterschiedliche Querschnitte aufweisen, was eine weitere Einflußmöglichkeit auf die Ausbringungsbedin¬ gungen für die feuchte Bausteinmasse eröffnet.Because of the vibration excitation of the sieve bottom, a risk of clogging can be largely ruled out. It is therefore possible to use different sieve trays. Particularly favorable Ausbringungsverhältnis¬ se arise, however, if the sieve bottom consists of a grid. The bars of this grid can also have different cross-sections, which opens up a further possibility of influencing the Ausbringungsbedin¬ conditions for the wet building block mass.

Weg zur Ausführung der ErfindungWay to carry out the invention
Gemäß dem dargestellten Ausführungsbeispiel weist die Vorrichtung zum Herstellen eines Hohlbausteins eine nach oben offene Form 1 auf, die aus einem Formboden 2 und einem auf den Formboden*2 aufgesetzten Formka¬ sten 3 besteht. Zur Ausbildung der Hohlkammern des zu .fertigenden Hohlbau¬ steins dienen Kernstege 4, die den Formboden 2 durchsetzten und mit Hilfe eines Stempels 5 zum Entformen des Hohlbausteins durch den Formboden 2 aus dem Formraum gezogen werden können. Oberhalb der Form 1 ist eine Führung 6 vorgesehen, die zwei seitliche Führungsschienen 7 für die Laufrollen 8 eines Füllwagens 9 umfaßt. Diese Führung 6 bildet Anschläge 10 für eine Füllstellung des Füllwagens 9 oberhalb der Form 1. Zum Antrieb des Füllwa¬ gens 9 dient ein Stelltrieb 11, beispielsweise ein Stellzylinder, mit dessen Hilfe der Füllwagen 9 in der Anschlagstellung verriegelt werden kann.According to the illustrated embodiment, the device for producing a hollow block on an upwardly open mold 1, which consists of a mold bottom 2 and a 3 placed on the mold bottom * 2 Formka¬. For forming the hollow chambers of the hollow body to be finished, core webs 4 are used, which pass through the mold bottom 2 and can be pulled out of the mold space by means of a punch 5 for demolding the hollow component through the mold bottom 2. Above the mold 1, a guide 6 is provided which comprises two lateral guide rails 7 for the rollers 8 of a filling carriage 9. This guide 6 forms stops 10 for a Filling position of the filling carriage 9 above the mold 1. To drive the Füllwa¬ gene 9 is an actuator 11, for example, a control cylinder, with the aid of the filling carriage 9 can be locked in the stop position.
Der Füllwagen 9 bildet einen nach oben offenen Aufnahmeraum 12 für eine hydraulisch aushärtende, feuchte Bausteinmasse, aus der der Hohlbaustein gefertigt wird. Der Aufnahmeraum 12 wird durch Umfangswände 13 sowie einen Siebboden 14 begrenzt, der in einer Verschiebeführung 15 des Füllwa¬ gens 9 schwingungsfähig gelagert und an einem Schwingungsantrieb 16 ange¬ schlossen ist. Dieser Schwingungsantrieb 16 ist als Exzentertrieb ausgebildet und weist einen durch einen Elektromotor 17 angetriebenen Exzenter 18 auf, an dem eine am Siebboden 14 angreifende Pleuelstange 19 angelenkt ist. Zum Verstellen der Schwenkweite des Schwingungsantriebes 16 ist die Anlenkach- se 20 für die Pleuelstange 19 auf dem Exzenter 18 radial verstellbar gelagert. Über den Elektromotor 17 kann außerdem die Schwingungsfrequenz einge¬ stellt werden, so daß der Siebboden 14 hinsichtlich seiner Schwingungsanre¬ gung in einfacher Weise an die jeweiligen Anforderungen bezüglich der Bau¬ steinmasse angepaßt werden kann.The filling carriage 9 forms an upwardly open receiving space 12 for a hydraulically hardening, moist building block mass, from which the hollow building block is manufactured. The receiving space 12 is delimited by peripheral walls 13 and a sieve bottom 14, which is mounted to oscillate in a displacement guide 15 of the filling jig 9 and is connected to a vibration drive 16. This vibration drive 16 is designed as an eccentric drive and has an eccentric 18 driven by an electric motor 17, to which a connecting rod 19 engaging the sieve bottom 14 is articulated. To adjust the swivel width of the vibration drive 16, the Anlenkach- se 20 for the connecting rod 19 is mounted radially adjustable on the eccentric 18. In addition, the vibration frequency can be adjusted via the electric motor 17, so that the sieve bottom 14 can be adapted in a simple manner with respect to its vibration excitation to the respective requirements with respect to the structural mass of the stone.
Der Siebboden 14 ist als Gitterrost ausgebildet und weist unterschiedlich große Sieböffnungen zwischen den einzelnen Gitterstäben auf, wie dies insbesondere der Fig. 1 entnommen werden kann. Der Querschnitt der Sieböffnungen ist dabei nach oben begrenzt, um einen freien Durchtritt der feuchten Baustein¬ masse durch den Siebboden aufgrund des Eigengewichtes zu unterbinden. Dadurch wird es möglich, den mit der feuchten Bausteinmasse gefüllten Füll¬ wagen 9 ohne eine Austragung der Bausteinmasse in die Füllstellung nach der Fig. 1 zu verfahren. Erst in der verriegelten Füllstellung wird der Schwingungs¬ antrieb 16 für den Siebboden 14 eingeschaltet, um die Bausteinmasse aus dem Aufnahmeraum 12 in die unter dem Siebboden 14 befindliche Form 1 auszubringen. Aufgrund der unterschiedlich großen Sieböffnungen wird der zufolge der Reibung zwischen den Umfangswänden 13 und der Baustein¬ masse ungleichmäßige Austrag ausgeglichen, so daß mit einer gleichmäßigen Befüllung der Form 1 mit der feuchten Bausteinmasse gerechnet werden kann, weil eben im Bereich der Umfangswände 13 der Siebboden 14 entsprechend größere Sieböffnungen aufweist. Da außerdem die Verteilung der Sieböffnun¬ gen in Abhängigkeit von dem Verlauf der Formwände und Kernstege 4 der Form 1 gewählt werden kann, kann auf die Verteilung der feuchten Baustein¬ masse in der Form 1 in einer Weise Einfluß genommen werden, die die ange¬ strebte gleichmäßige Befüllung der Form 1 sicherstellt. The sieve bottom 14 is formed as a grid and has different sized sieve openings between the individual bars, as can be seen in particular in FIG. 1. The cross-section of the sieve openings is limited upwards in order to prevent a free passage of the moist building block mass through the sieve bottom due to its own weight. As a result, it becomes possible to move the filling cart 9 filled with the moist building block mass into the filling position according to FIG. 1 without discharging the building block mass. Only in the locked filling position of the Schwingungs¬ drive 16 is turned on for the sieve plate 14 to deploy the block mass from the receiving space 12 in the located under the sieve tray 14 Form 1. Due to the different sized sieve openings, the uneven discharge due to the friction between the peripheral walls 13 and the building block mass is compensated, so that a uniform filling of the mold 1 with the moist building block mass can be expected. because just in the area of the peripheral walls 13 of the sieve plate 14 has correspondingly larger sieve openings. In addition, since the distribution of Sieböffnun¬ gene depending on the course of the mold walls and core webs 4 of the mold 1 can be selected, can be taken to the distribution of the wet building block in the mold 1 in a manner that sought the ange¬ ensures uniform filling of the mold 1.
