Description

Porenbetonblöcke werden in Formen gegossen und nach dem Erreichen der Grünstandsfestigkeit entschalt. Der noch plastische (grüne) Porenbetonblock, der eine Länge von etwa 6 - 7,5 m, eine Breite von etwa 2m und eine Höhe von etwa 65 - 75 cm hat, wird zu einer Schneidmaschine gebracht und dort mittels gespannter Stahldrähte in Längs- und Querrichtung geschnitten, so daß quaderförmige Porenbetonsteine, -blöcke oder auch -platten entstehen. Diese werden dann in einem Autoklaven dampfdruckgehärtet. Beim Schneiden des noch plastischen Porenbetonblockes wird an dessen Oberseite eine etwa 3 - 12 cm dicke Schicht abgetrennt, die vor dem Härten entfernt werden muß. Wenn der Porenbetonblock horizontal liegend geschnitten wird, handelt es sich bei dieser Abfallschicht um eine Schicht, die in ungleichmäßiger Höhe beim Treiben der Porenbetonmasse entsteht. Porenbetonblöcke werden jedoch auch gemäß der DE-C-958 639 nach dem Entschalen um 90° gekippt, so daß sie dann auf ihrer langen Schmalseite stehen und in dieser Stellung exakter geschnitten werden können. Nach dem Schneiden wird dann der Porenbetonblock vor dem Einbringen in den Autoklaven vorzugsweise wieder um 90° auf seine größte Breitseite gekippt (vgl. DE-A-21 08 300). Auch beim Schneiden eines hochkant stehenden Blockes wird oben eine bis zu 12 cm dicke Abfallschicht abgetrennt, weil die Schmalseite des plastischen Porenbetonblockes durch Schalöl verunreinigt sein kann, die seitliche Formwand nicht exakt eben ist oder auch meist in einem kleinen Winkel geneigt zur Breitseite des Porenbetonblockes verläuft und weil außerdem je nach dem Format der zu schneidenden Steine oder Platten ein Rest entsteht, der der oberen Schicht hinzugerechnet wird. AAC blocks are poured into molds and after reaching them the green stability. The still plastic one (green) aerated concrete block, which is about 6 - 7.5 m long, a width of about 2m and a height of about 65 - 75 cm has, is brought to a cutting machine and there by means of tensioned steel wires cut lengthways and crossways, so that cuboid porous concrete blocks, blocks or plates are created. These are then placed in an autoclave steam pressure hardened. When cutting the still plastic AAC block is about 3 - 12 cm at the top thick layer separated, which are removed before hardening got to. When the aerated concrete block is cut horizontally this waste layer is a layer at an uneven height when driving the aerated concrete mass arises. However, aerated concrete blocks are also made according to the DE-C-958 639 tilted 90 ° after demoulding, so that it then stand on their long narrow side and in this position can be cut more precisely. After cutting the aerated concrete block is then placed in the autoclave preferably again by 90 ° to its largest broadside tilted (see DE-A-21 08 300). Even when cutting one upright block becomes a up to 12 cm thick Waste layer separated because the narrow side of the plastic AAC block can be contaminated by formwork oil that lateral mold wall is not exactly flat or mostly in inclined at a small angle to the broad side of the cellular concrete block runs and because also depending on the format of the cutting stones or slabs creates a residue that the upper layer is added.

Eine bekannte Vorrichtung zum Entfernen der beim Beschneiden der Oberseite von plastischen Porenbetonblöcken od. dgl. entstehenden Abfallschicht (DE-B 1 683 837) weist einen von oben über den Block absenkbaren Saugkasten auf, der an seiner Unterseite eine Vielzahl von Durchbrechungen hat. Unterhalb dieser Durchbrechungen ist eine Abdeckvorrichtung in Form einer flexiblen Folie vorgesehen, die jalousieartig über einen Teil der Durchbrechungen gezogen werden kann, um diese abzudecken. Auf diese Weise kann die Vorrichtung zum Abheben verschieden großer Abfallschichten verwendet werden. Die vorbekannte Vorrichtung ist jedoch teuer in der Herstellung und im Betrieb. Da sie mit Vakuum arbeitet und beim Ansaugen der Abfallschicht Staub und Porenbetonteilchen in die Saugluft gelangen, sind Filter zum Entstauben dieser Luft notwendig, die regelmäßig gereinigt werden müssen. Wenn durch Stromausfall oder eine sonstige Betriebsstörung das Vakuum plötzlich ausfällt, kann sich außerdem die von der Vorrichtung angehobene Abfallschicht von dem Saugkasten lösen und auf den darunter befindlichen, bereits geschnittenen Porenbetonblock herunterfallen. Bereits hierbei, spätestens jedoch beim Entfernen der dann zerbrochenen Abfallschicht von Hand, werden die obersten Porenbetonsteine bzw. -platten beschädigt und sind dann ebenfalls Abfall.A known device for removing the pruning the top of plastic aerated concrete blocks or the like Waste layer (DE-B 1 683 837) has one of above the block lowerable suction box on the has numerous perforations on its underside. Below these openings is a cover device provided in the form of a flexible film that is jalousie-like can be pulled over part of the openings to cover these. In this way, the device for Lifting off different sized waste layers can be used. However, the previously known device is expensive to manufacture and in operation. Since she works with vacuum and at Aspiration of the waste layer of dust and aerated concrete particles get into the suction air, are filters for dusting them Air necessary, which must be cleaned regularly. If due to a power failure or other malfunction the vacuum suddenly fails, that of the device lifted waste layer from the suction box loosen and on the already cut ones underneath AAC block falling down. Already here, at the latest however, when removing the then broken layer of waste by hand, the top aerated concrete blocks or plates are damaged and are then also waste.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Entfernen der beim Schneiden von plastischen Porenbetonblöcken, insbesondere hochkant stehenden Porenbetonblöcken oder dgl., entstehenden oberen Abfallschicht zu schaffen, die kostengünstig herstellbar ist, geringe Betriebskosten verursacht und auch eine hohe Lebensdauer aufweist.The invention has for its object a device to remove the when cutting plastic aerated concrete blocks, especially upright aerated concrete blocks or the like to create the resulting upper waste layer, which is inexpensive to manufacture, low operating costs caused and also has a long life.

Eine solche Vorrichtung ist nach der Erfindung gekennzeichnet durch

  • eine sich oberhalb des Porenbetonblockes in dessen Längsrichtung erstreckende heb- und senkbare Traverse,
  • mindestens zwei daran motorisch höhenbeweglich gelagerte horizontale Tragrahmen, die paarweise einander gegenüberstehend zu beiden Seiten einer vertikalen Längsmittelebene der Traverse unterhalb derselben angeordnet sind,
  • und eine Vielzahl von in die Abfallschicht einstechbaren Nägeln, die an der Unterseite jedes Tragrahmens vorgesehen und die mit ihren Spitzen schräg nach unten gerichtet sind, wobei alle Nägel des ersten Tragrahmens jedes Rahmenpaares zueinander parallel und in einem spitzen Winkel gegenüber der Längsmittelebene geneigt sind und alle Nägel des gegenüberliegenden zweiten Tragrahmens zueinander parallel und in einem entgegengesetzten spitzen Winkel gegenüber der Längsmittelebene geneigt sind, und wobei jeder Tragrahmen in Richtung seiner Nägel gegenüber der Traverse verschiebbar ist.
  • Such a device is characterized according to the invention
  • a lifting and lowering traverse extending above the aerated concrete block in its longitudinal direction,
  • at least two horizontal support frames mounted thereon in a motor-vertically movable manner, which are arranged in pairs opposite one another on both sides of a vertical longitudinal center plane of the cross member,
  • and a plurality of nails pierceable into the waste layer which are provided on the underside of each supporting frame and which are directed obliquely downwards with their tips, all nails of the first supporting frame of each pair of frames being parallel to one another and inclined at an acute angle with respect to the longitudinal median plane, and all Nails of the opposite second support frame are parallel to one another and inclined at an opposite acute angle with respect to the longitudinal center plane, and each support frame is displaceable in the direction of its nails with respect to the crossmember.
  • Die Erfindung geht also von dem Gedanken aus, die Abfallschicht mittels einer Vielzahl von Nägeln, die von zwei entgegengesetzten Seiten her schräg von oben nach unten in die Abfallschicht eingestochen werden und dann mittels der Tragrahmen synchron angehoben werden, rein mechanisch, d.h. ohne Saugluft, zu erfassen und nach oben von dem übrigen Porenbetonblock abzuheben. Da hierbei keine mit Staub und Porenbetonteilchen verunreinigte Saugluft entsteht, können jegliche Luftfilter und deren Wartung entfallen. Die Vorrichtung selbst besteht aus relativ einfachen mechanischen Bauteilen und benötigt nur eine verhältnismäßig geringe Antriebsleistung, wodurch sie kostengünstig herstellbar ist und auch im Betrieb nur geringe Betriebskosten verursacht. Bei der erfindungsgemäßen Vorrichtung werden ferner die Nägel, sobald sie in die Abfallschicht eingestochen sind, durch das Gewicht derselben und das Gewicht der beweglichen Teile der Vorrichtung in "Greifstellung" gehalten, so daß bei plötzlicher Unterbrechung der Energiezufuhr, z.B. bei Stromausfall, die von den Nägeln erfaßte Abfallschicht nicht abstürzen kann. The invention is therefore based on the idea of the waste layer by means of a variety of nails made by two opposite sides diagonally from top to bottom be stabbed into the waste layer and then by means of the support frame can be lifted synchronously, purely mechanically, i.e. without suction air, to capture and up from that lift off the remaining aerated concrete block. Since no one here Dust and aerated concrete particles are contaminated, any air filter and its maintenance can be omitted. The device itself consists of relatively simple ones mechanical components and only requires a proportionate low drive power, making them inexpensive is manufacturable and only minor in operation Operating costs caused. In the device according to the invention will also become the nails once they are in the waste layer are stabbed by the weight of the same and the weight of the moving parts of the device in "Gripping position" held so that when suddenly interrupted the energy supply, e.g. in the event of a power failure, the layer of waste caught by the nails cannot fall.

    Die erfindungsgemäße Vorrichtung ist Bestandteil einer Schneidemaschine zum Schneiden eines auf seiner langen Schmalseite stehenden plastischen Porenbetonblockes. Die Vorrichtung ist in dieser Schneidmaschine oberhalb der langen oberen Schmalseite des Porenbetonblockes angeordnet und weist eine in einem nicht dargestellten Gestell heb- und senkbare Traverse 1 auf, die sich parallel zur langen Schmalseite des Porenbetonblockes erstreckt. Unterhalb der Traverse 1 sind an dieser mehrere Paare P von Tragrahmen 2, 2' angeordnet. Die Tragrahmen 2, 2' sind paarweise einander gegenüberstehend zu beiden Seiten einer vertikalen Längsmittelebene M angeordnet. An der Unterseite dieser horizontalen Tragrahmen 2, 2' sind jeweils mehrere Tragschienen 3, 3' angeschweißt, die ebenfalls horizontal angeordnet sind und sich senkrecht zur Längsmittelebene M erstrecken. Die Tragschienen sind in gegenseitigem Abstand a voneinander nach der Art der Zinken eines Rechens angeordnet, wobei sie an den einander zugewandten Längsseiten 2a, 2'a jedes Rahmenpaares P überkragen. Wie man aus Figur 3 erkennen kann, greifen die Tragschienen 3 des ersten Tragrahmens 2 in die Lücken zwischen den Tragschienen 3' des zweiten Tragrahmens 2' ein und umgekehrt.The device according to the invention is part of a Cutting machine to cut one on its long one Narrow side of standing aerated concrete block. The Device is above the in this cutting machine long upper narrow side of the cellular concrete block and has one in a frame, not shown lifting and lowering crossbar 1, which is parallel to long narrow side of the cellular concrete block extends. Below the traverse 1 are on this several pairs P of Support frame 2, 2 'arranged. The support frames 2, 2 'are in pairs facing each other on both sides a vertical longitudinal median plane M is arranged. At the Bottom of this horizontal support frame 2, 2 'are each several mounting rails 3, 3 'welded, which also are arranged horizontally and perpendicular to Extend the median longitudinal plane M. The mounting rails are in mutual distance a from each other according to the type of Tines of a rake are arranged, facing each other facing longitudinal sides 2a, 2'a of each pair of frames P overhang. As can be seen from Figure 3, the Support rails 3 of the first support frame 2 in the gaps between the support rails 3 'of the second support frame 2' one and vice versa.

    Die Tragschienen 3, 3' sind, wie insbesondere aus Figur 5 hervorgeht, jeweils als ein nach unten offenes C-Profil ausgebildet. In dieses C-Profil ist von der Stirnseite jeder Tragschiene 3, 3' her eine beispielsweise aus einer Aluminiumlegierung bestehende Nagelleiste 4 einschiebbar.The mounting rails 3, 3 'are, as in particular from FIG. 5 emerges, each as a downward open C-profile educated. This C-profile is from the front each mounting rail 3, 3 'forth one example an aluminum alloy existing nail bar 4 can be inserted.

    An jeder Nagelleiste 4 sind mehrere, z.B. sechs, lange Nägel 5 schräg geneigt, in gleichen Abständen voneinanander und parallel zueinander angeordnet, so daß sie schräg nach unten von der Nagelleiste 4 vorstehen. Die Nägel 5 des ersten Tragrahmens 2 sind dabei in einem spitzen Winkel µ von etwa 25 - 35°, vorzugsweise 30°, gegenüber der Längsmittelebene M geneigt. Alle Nägel 5, die dem ersten Tragrahmen 2 zugeordnet sind, verlaufen parallel zueinander und sind unter dem gleichen Winkel µ gegenüber der Längsmittelebene geneigt. Der erste Tragrahmen 2 ist in Richtung B, die parallel zu der Längsrichtung der Nägel 5 verläuft, gegenüber der Traverse 1 verschiebbar. Die Nägel 5' des zweiten Tragrahmens 2' sind in gleicher Weise jeweils in Nagelleisten angeordnet, welche in die Tragschienen 3' eingeschoben sind, wobei alle Nägel, die dem zweiten Tragrahmen 2' zugeordnet sind, parallel zueinander angeordnet, jedoch in einem spitzen Winkel µ1, der entgegengesetzt zum spitzen Winkel µ ist, gegenüber der Längsmittelebene M geneigt sind. Der Winkel µ1 kann gleich groß sein wie der Winkel µ. Ein Winkel von 25 - 35°, vorzugsweise 30°, hat sich überraschenderweise als besonders vorteilhaft erwiesen, da hiermit die grüßten Haltekräfte in dem relativ weichen, plastischen Porenbeton erzielt werden und die geringste Gefahr eines Ausbrechens dieses Porenbetons besteht. Der zweite Tragrahmen 2' ist in Längsrichtung seiner Nägel 5' in Richtung C gegenüber der Traverse 1 verschiebbar.There are several, e.g. six, long Nails 5 inclined at an equal distance from each other and arranged parallel to each other so that they protrude diagonally downwards from the nail bar 4. The Nails 5 of the first support frame 2 are in one acute angle µ of about 25-35 °, preferably 30 °, inclined with respect to the longitudinal median plane M. All nails 5, which are assigned to the first support frame 2 parallel to each other and are at the same angle µ inclined with respect to the longitudinal median plane. The first supporting frame 2 is in direction B, which is parallel to the longitudinal direction of the nails 5 runs relative to the crossbar 1 slidable. The nails 5 'of the second support frame 2' are arranged in the same way in nail strips, which are inserted into the mounting rails 3 ', all nails associated with the second support frame 2 ' are arranged parallel to each other, but in one acute angle µ1, which is opposite to the acute angle µ is inclined with respect to the longitudinal median plane M. Of the Angle µ1 can be the same size as the angle µ. A Angle of 25-35 °, preferably 30 °, has surprisingly been found proven to be particularly advantageous since this the greatest holding forces in the relatively soft, plastic Aerated concrete can be achieved and the least risk there is a breakout of this aerated concrete. The second Support frame 2 'is in the longitudinal direction of its nails 5' in Movable in direction C relative to the crossbar 1.

    Die Nägel 5, 5', die vorteilhaft eine Länge von etwa 200 mm und einen Durchmesser von 2,5 - 5 mm, vorzugsweise etwa 3 mm, aufweisen, sind jeweils von oben her in schräge Bohrungen 7 der Nagelleisten 4 eingeschoben, so daß ihre Spitzen nach unten gerichtet sind und sich ihr Kopf in einer Absenkung an der Oberseite der Nagelleiste befindet. Wenn die Nagelleiste 4 in die Tragschiene 3 bzw. 3' eingeschoben ist, dann können sich die Köpfe der Nägel an der Innenseite der Tragschiene 3 abstützen und sind somit sicher gehalten. Sollte es zu einem Bruch oder einem Verbiegen eines Nagels kommen, so kann die zugehörige Nagelleiste 4 leicht aus der Tragschiene 3 herausgezogen und der beschädigte Nagel durch einen neuen ersetzt werden. Damit die Nagelleisten 4 in der zugehörigen Tragschiene 3 gehalten sind, weist jede Tragschiene 3 an ihrem einen Ende eine Federklammer 8 auf, die die stirnseitige Öffnung der Tragschiene 3 teilweise überdeckt, und an ihrem anderen Ende einen stationären Lappen 9, der als Anschlag für die Nagelleiste dient.The nails 5, 5 ', which advantageously have a length of about 200 mm and a diameter of 2.5 - 5 mm, preferably about 3 mm, are inclined from above Bores 7 of the nail strips 4 inserted so that their Tips are pointed down and their heads in a depression is located at the top of the nail bar. When the nail bar 4 is inserted into the mounting rail 3 or 3 ' then the heads of the nails can touch each other support the inside of the mounting rail 3 and are thus kept safe. Should it break or bend of a nail, the associated nail bar can 4 slightly pulled out of the mounting rail 3 and the damaged nail can be replaced with a new one. So that the nail strips 4 in the associated mounting rail 3 are held, each mounting rail 3 has on its one End a spring clip 8 on the front opening the mounting rail 3 partially covered, and on their other End a stationary tab 9, which acts as a stop for the Nail bar is used.

    Zur höhenbeweglichen, verschiebbaren Lagerung der Tragrahmen 2, 2' weist jeder derselben zwei Führungsstangen 10, 10' auf, die im gleichen spitzen Winkel µ, µ1 gegenüber der Längsmittelebene M geneigt sind, wie die zugehörigen Nägel 5 bzw. 5'. Für jede Führungsstange 10, 10' ist an der Traverse 1 eine entsprechend geneigte Führungsbüchse 11, 11' vorgesehen, in welcher die zugehörige Führungsstange 10, 10' verschiebbar ist. For height-adjustable, slidable mounting of the support frame 2, 2 'each have the same two guide rods 10, 10 'on the opposite at the same acute angle µ, µ1 the longitudinal center plane M are inclined, like the associated ones Nails 5 or 5 '. For each guide rod 10, 10 ' is a correspondingly inclined guide bush on the crossbar 1 11, 11 'provided in which the associated Guide rod 10, 10 'is displaceable.

    An jeder Seite der Längsmittelebene M der Traverse 1 sind sechs gleichartig ausgestaltete Tragrahmen 2 bzw. 2' angeordnet. Damit diese synchron auf- und abbewegt werden können, ist bei dem gezeigten Ausführungsbeispiel für jede Traversenseite ein gemeinsamer Stellmotor 13 vorgesehen, der als Schrittmotor ausgebildet ist. Der Stellmotor 13 treibt über ein Winkelgetriebe 14 und mehrere Wellenstücke 15 je ein Stellgetriebe 16 für jeden Tragrahmen 2 bzw. 2' an. Das Stellgetriebe 16 enthält eine über ein Winkelgetriebe angetriebene Spindelmutter, die eine parallel zu den Führungsstangen 10 bzw. 10' verlaufende Gewindespindel 17 umgibt. Bei Drehung der Spindelmutter wird die Gewindespindel gegenüber dem Stellgetriebe 16 verschoben und bewegt somit den zugeordneten Tragrahmen 2 bzw. 2' in Richtung B bzw. C (Figur 1). Auf diese Weise können alle Tragrahmen 2 bzw. 2' an einer Seite der Traverse 1 synchron auf- und abbewegt werden. Die beiden Stellmotoren zu jeder Seite der Traverse 1 können über eine sogenannte elektrische Welle gekuppelt sein, wodurch man alle Tragrahmen 2 und 2' an beiden Seiten der Traverse synchron auf- und abbewegen kann. Es wäre auch denkbar, für jeden Tragrahmen einen eigenen Stellmotor vorzusehen und die Stellmotoren untereinander durch elektrische Wellen zu synchronisieren. Auch hydraulische oder pneumatische Stellmotoren wären denkbar.On each side of the longitudinal median plane M of the traverse 1 six identical support frames 2 and 2 'arranged. So that they are moved up and down synchronously can, is in the embodiment shown for each A common servomotor 13 is provided on the traverse side, which is designed as a stepper motor. The servomotor 13 drives via an angular gear 14 and several shaft pieces 15 an actuating gear 16 for each support frame 2 or 2 ' on. The actuating gear 16 contains an angular gear driven spindle nut which is parallel to one the threaded rods 17 running the guide rods 10 or 10 ' surrounds. When the spindle nut turns, the threaded spindle becomes shifted and moved relative to the actuating gear 16 thus the associated support frame 2 or 2 'in the direction B and C (Figure 1). In this way, all support frames 2 or 2 'on one side of the crossbar 1 synchronously be moved up and down. The two servomotors to each Side of the crossmember 1 can have a so-called electrical Shaft coupled, which means that all support frames 2 and 2 'on both sides of the crossbar up and in synchronism can move. It would also be conceivable for any support frame to provide a separate servomotor and the servomotors synchronize with each other through electrical waves. Hydraulic or pneumatic servomotors would also be conceivable.

    Wie bereits oben erläutert wurde, können die abzuhebenden Abfallschichten unterschiedliche Dicken aufweisen. In Figur 2 ist mit einer strichpunktierten Linie eine Abfallschicht A mit der größten zu erwartenden Dicke D angedeutet. Die Dicke der Abfallschicht ist infolge der schräg geneigten Seitenwand der Gießform über die Breite der Abfallschicht bei dem gezeigten Ausführungsbeispiel zunehmend. Es gibt jedoch auch Formen mit Seitenwänden, die genau senkrecht zum Boden verlaufen, so daß dann die Abfallschicht über ihre Breite eine gleichbleibende Dicke aufweist. Damit die Abfallschicht von den Nägeln 5, 5' sicher getragen wird, ist es erforderlich, daß die Nägel annähernd über die volle Dicke D in die Abfallschicht eindringen. Sie dürfen die Abfallschicht jedoch nicht vollständig durchdringen, da sonst die Oberseiten der unterhalb der Abfallschicht liegenden Porenbetonkörper beschädigt würden. Aus diesem Grund ist es zweckmäßig, wenn die Einstechtiefe so eingestellt wird, daß zwischen der unteren Begrenzungsfläche der Abfallschicht und den Spitzen der Nägel 5, 5' ein Sicherheitsabstand von beispielsweise 5 mm verbleibt. Damit nun auch Abfallschichten abgehoben werden können, deren Dicke geringer ist als die in Figur 2 dargestellte Dicke D, ist der Hub der Tragrahmen 2, 2' in Richtung der zugehörigen Nägel 5, 5' einstellbar. Die Einstellung dieses Hubes erfolgt mit Hilfe des als Schrittmotor ausgebildeten Stellmotors 13.As already explained above, the ones to be withdrawn can Waste layers have different thicknesses. In Figure 2 is a waste layer with a dash-dotted line A indicated with the greatest expected thickness D. The thickness of the waste layer is due to the sloping Side wall of the mold over the width of the waste layer increasingly in the embodiment shown. However, there are shapes with side walls that are accurate run perpendicular to the ground so that the waste layer has a constant thickness over its width. So that the waste layer from the nails 5, 5 'is safe is worn, it is necessary that the nails approximate penetrate the full thickness D into the waste layer. she however, must not completely penetrate the waste layer, otherwise the tops of the below the waste layer lying aerated concrete body would be damaged. Out For this reason, it is advisable if the penetration depth is like this that is set between the lower boundary surface the waste layer and the tips of the nails 5, 5 ' a safety distance of, for example, 5 mm remains. So that layers of waste can now also be lifted off, whose thickness is less than that shown in Figure 2 Thickness D, the stroke of the support frame 2, 2 'in the direction of associated nails 5, 5 'adjustable. The setting of this Stroke takes place with the help of the stepper motor Servomotor 13.

    Bei dem gezeigten Ausführungsbeispiel ist ferner mit Abstand unterhalb der Tragrahmen 2, 2' eine Blechplatte 18 angeordnet, die über vertikale Stützen 19 fest mit der Traverse 1 verbunden ist. Die Blechplatte 18 ist im wesentlichen horizontal angeordnet, worunter hier auch eine geringfügige Neigung gegenüber der Horizontalen verstanden wird, wobei der Neigungswinkel gegenüber der Horizontalen dem Neigungswinkel der Formseitenwände gegenüber der Vertikalen entspricht. An der Unterseite der Blechplatte 18 ist eine Moosgummiplatte 20 vorgesehen. Die Blechplatte 18 mit der Moosgummiplatte 20 dient in erster Linie dazu, den Porenbetonblock beim Querschneiden abzustützen. Das Querschneiden erfolgt dadurch, daß mehrere in einem Rahmen gespannte Drähte durch Bewegung des Rahmens von unten nach oben durch den Porenbetonblock bewegt werden. Damit das plastische Material des Porenbetonblockes an dessen oberer Schmalseite nicht ausbricht, wenn die Drähte in die Nähe der oberen Schmalseite gelangen, wird die obere Schmalseite durch die Blechplatte 18 und die Moosgummiplatte 20 abgestützt. Die Schneiddrähte liegen an der Moosgummiplatte 20 an, wenn der Querschneidvorgang beendet ist.In the embodiment shown is also at a distance a sheet metal plate 18 below the support frames 2, 2 ' arranged, the vertical supports 19 fixed to the Traverse 1 is connected. The sheet metal plate 18 is essentially arranged horizontally, including a slight one here Understand inclination to the horizontal the angle of inclination relative to the horizontal the angle of inclination of the mold side walls with respect to the vertical corresponds. At the bottom of the sheet metal plate 18 is a foam rubber plate 20 is provided. The plate 18 with the foam rubber plate 20 serves primarily to Support the aerated concrete block during cross cutting. The cross cutting is done by having several in one frame tensioned wires by moving the frame from bottom to bottom be moved up through the aerated concrete block. So that plastic material of the aerated concrete block on its upper Narrow side does not break out when the wires are close the upper narrow side, the upper narrow side supported by the sheet metal plate 18 and the foam rubber plate 20. The cutting wires lie on the foam rubber plate 20 when the cross cutting process is finished.

    Damit nun die Nägel 5, 5' durch die Blechplatte 18 hindurchtreten können, ist diese im Bewegungsbereich jedes Nagels 5, 5' mit einer ausreichend großen Durchbrechung 21, z.B. einer Bohrung, versehen. Die Moosgummiplatte 20 braucht keine Durchbrechungen aufzuweisen, denn sie wird von den spitzen Nägeln 5, 5' einfach durchstochen. Wenn die Nägel 5, 5' beim Anheben der Tragrahmen 2, 2' nach oben aus der Moosgummiplatte 20 herausgezogen werden, dann dient die Moosgummiplatte 20 zusammen mit der Blechplatte 18 als Abstreifer, der etwaige an den Nägeln 5, 5' anhaftende Porenbetonreste abstreift. Da sich die abgestreiften Reste an der Unterseite der Moosgummiplatte 20 befinden, fallen sie einfach herunter.So that the nails 5, 5 'now pass through the sheet metal plate 18 is in the range of movement of each nail 5, 5 'with a sufficiently large opening 21, e.g. a hole. The foam rubber sheet 20 needs no breakthroughs because it is used by the pointed nails 5, 5 'simply pierced. If the nails 5, 5 'when lifting the support frame 2, 2' upwards from the Foam rubber plate 20 are pulled out, then the Foam rubber plate 20 together with the sheet metal plate 18 as Scraper, any adhering to the nails 5, 5 ' Remains of aerated concrete. Since the stripped remains located on the underside of the foam rubber sheet 20, fall just down them.

    Die Wirkungsweise der neuen Vorrichtung ist folgende:The new device works as follows:

    Der auf seiner langen Schmalseite stehende plastische Porenbetonblock wird zunächst durch horizontale Schneiddrähte in Längsrichtung geschnitten, wobei durch einen an oberster Stelle angeordneten Schneiddraht eine obere Abfallschicht abgetrennt wird. Die Traverse 1 befindet sich mit den daran angeordneten Tragrahmen 2, 2' und der Blechplatte 18 in ihrer oberen Stellung, damit die Bewegung des Längsschneidrahmens nicht behindert wird. Nach Beendigung des Längsschneidens wird die Traverse 1 vertikal nach unten abgesenkt, wobei sich die Tragrahmen 2, 2' in der in Figur 1 dargestellten Freigabestellung befinden. Das Absenken der Traverse 1 erfolgt so weit, bis die Moosgummiplatte 20 an der oberen Schmalseite des Porenbetonblockes anliegt. Es erfolgt dann das Querschneiden von unten nach oben, bis die Schneiddrähte an der Moosgummiplatte 20 anliegen. Durch Betätigung der Stellmotoren 13 werden nunmehr die Tragrahmen 2, 2' schräg nach unten verschoben, wobei die Nägel 5, 5' von zwei entgegengesetzten Seiten her schräg von oben nach unten in die Abfallschicht eingestochen werden, bis sich ihre Spitzen in einem Sicherheitsabstand von 5 mm oberhalb der unteren Begrenzungsfläche der Abfallschicht befinden. Diese Greif- oder Haltestellung der Tragrahmen 2, 2' und ihrer Nägel 5, 5' ist in Figur 2 dargestellt. In dieser Stellung der Tragrahmen 2, 2' wird die Traverse 1 wieder angehoben, wobei die in die Abfallschicht eingestochenen Nägel 5, 5' diese mit anheben. Da die Nägel jeder Nagelleiste 4 in einem gegenseitigen horizontalen Abstand von etwa 90 mm angeordnet sind und der horizontale Abstand einer Reihe von Nägeln 5 gegenüber der nächsten Reihe von Nägeln 5' nur etwa 40 mm beträgt, ist die Abfallschicht durch eine Vielzahl von Nägeln in verhältnismäßig geringen Abständen gehalten. Nachdem die Abfallschicht in der beschriebenen Weise angehoben wurde, wird der in Längs- und Querrichtung geschnittene Porenbetonblock um 90° auf seine Breitseite zurückgekippt und anschließend in einen Autoklaven gebracht. Sobald der Porenbetonblock aus dem Bereich unterhalb der Traverse entfernt ist, werden die Tragrahmen 2, 2' mittels der Stellmotoren 13 aus ihrer unteren Greif- oder Haltestellung schräg nach oben bewegt, wobei die Nägel 5, 5' aus der Abfallschicht herausgezogen werden. Diese verliert hierdurch ihren Halt und fällt nach unten auf ein am Boden der Schneidmaschine vorgesehenes Transportband, durch welches die beim Herunterfallen zerbrechende Abfallschicht abtransportiert wird. Die noch plastische Porenbetonmasse der Abfallschicht wird als sogenannter Frischabfall der Porenbetonmasse einer weiteren Charge hinzugemischt.The plastic aerated concrete block standing on its long narrow side is first cut in by horizontal cutting wires Cut lengthwise, with one at the top Place an upper waste layer in place of the cutting wire is separated. The traverse 1 is located on it arranged support frame 2, 2 'and the sheet metal plate 18 in their upper position so that the movement of the slitter is not hindered. After slitting has been completed the traverse 1 is lowered vertically, wherein the support frame 2, 2 'in that shown in Figure 1 Release position. Lowering the traverse 1 takes place until the foam rubber plate 20 on the upper Narrow side of the cellular concrete block is in contact. Then it happens the cross cutting from the bottom up until the cutting wires rest on the foam rubber sheet 20. By pressing the Servomotors 13 are now the support frame 2, 2 'obliquely shifted downwards, the nails 5, 5 'of two opposite Sides diagonally from top to bottom in the layer of waste is pierced until their Tips at a safety distance of 5 mm above the lower boundary surface of the waste layer. This gripping or holding position of the support frame 2, 2 'and their nails 5, 5 'is shown in Figure 2. In this Position of the support frame 2, 2 'is the cross member 1 again raised, with those pierced into the waste layer Raise nails 5, 5 'with them. Because the nails of every nail bar 4 at a mutual horizontal distance of are arranged about 90 mm and the horizontal distance one row of nails 5 versus the next row of Nails 5 'is only about 40 mm, is the waste layer through a variety of nails in relatively small Distances kept. After the waste layer described in the Was raised in the longitudinal and AAC block cut transversely to its 90 ° Broadside tipped back and then in an autoclave brought. Once the aerated concrete block is out of the area is removed below the crossbar, the support frame 2, 2 'by means of the actuators 13 from their lower gripping or Stop position moved obliquely upwards, the Nails 5, 5 'are pulled out of the waste layer. This loses its hold and falls down on a conveyor belt provided on the bottom of the cutting machine, through which the one breaking when falling Waste layer is removed. The still plastic one AAC mass of the waste layer is known as Fresh waste of the aerated concrete mass of another batch mixed in.
