Abstract

To remove, in particular, worn coatings (12) from double bottom plates (10) quickly and automatically, preferably three removing devices (17) with motor-driven separating knives (18) are built into an apparatus (13) which has, underneath the removing devices (17), a slide (29) with mountings (31) for the double bottom plate (10) to be processed. The slide (29) can be reciprocated by motor transversely to the separating knives (18) of the removing devices (17) or parallel to the longitudinal axis of the apparatus (13). The removing devices (17) are mounted on a receiving plate (21) so as to be pivotable in each case about a horizontal axis (19). The receiving plates (21) are, for their part, mounted spring-loaded on a transversely extending, portal-like frame part (15), so as to be movable to a limited degree in the direction of the longitudinal axis of the apparatus (13). The slide (29) is reciprocated via a travelling nut (38) by means of a threaded spindle (39) which is mounted on the frame (14) of the apparatus (13) so as to be rotationally movable, but axially fixed and is driven alternately in both directions of rotation. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Gerät zum Abtrennen von Deckbelägen an Doppelbodenplatten oder dgl., mit einem motorisch angetriebenen Trennmesser.The invention relates to a device for separating coverings on raised floor panels or the like, with a motor-driven cutting knife.

Bekannte derartige Geräte werden als Handgeräte für die Entfernung von großflächig auf ortsfesten Unterböden verlegten Teppichböden verwendet, wenn deren Auswechslung, z. B. wegen Verschleisses oder auch aus anderen Gründen erwünscht ist. Diese Geräte eignen sich auch zum Ablösen von anderen textilen Bodenbelägen, PVC-Filz oder-Fliesen usw. Zum Abtrennen von Deckbelägen an Doppelbodenplatten sind sie jedoch nur bedingt brauchbar, denn hierbei besteht die Gefahr, daß der tragende Plattenteil insbesondere am empfindlichen Kanten- oder Randbereich beschädigt wird. Außerdem wäre das Abtrennen von Deckbelägen an Doppelbodenplatten mit solchen bekannten Geräten sehr zeitaufwendig, denn es müßte äußerst sorgfältig gearbeitet werden. Für den Einsatz vor Ort, d. h. also für den Baustelleneinsatz zur Doppelbodensanierung sind diese bekannten Geräte praktisch nicht geeignet.Known devices of this type are used as hand-held devices for the removal of carpets laid extensively on fixed subfloors if their replacement, for. B. is desired due to wear or for other reasons. These devices are also suitable for removing other textile floor coverings, PVC felt or tiles, etc. However, they can only be used to a limited extent to remove top coverings on raised floor panels, because there is a risk that the load-bearing panel part, particularly on the sensitive edge or edge area is damaged. In addition, the removal of coverings on raised floor panels with such known devices would be very time consuming, because it would have to be worked extremely carefully. For use on site, d. H. So these known devices are practically unsuitable for use on construction sites for raised floors.

Der Erfindung liegt die Aufgabe zugrunde, eine leistungsfähige Vorrichtung zum selbsttätigen Abtrennen der Deckbeläge von Doppelbodenplatten oder dergleichen zu schaffen, die jegliche Gefahr einer Beschädigung des tragenden Plattenteils beim Abtrennvorgang vermeidet.The invention has for its object to provide a powerful device for automatically separating the coverings from raised floor panels or the like, which any risk of damage to the supporting plate part avoided during the separation process.

Gemäß der Erfindung wird obige Aufgabe dadurch gelöst, daß

  • a) das Abtrenngerät ein Teil einer Vorrichtung zum selbsttätigen Abtrennen der Deckbeläge bildet und um eine horizontale Achse schwenk- bzw. einstellbar an einer Aufnahmeplatte befestigt ist, die in einer horizontalen oder etwa horizontalen Ebene an einem quer angeordneten Rahmenteil der Vorrichtung abgefedert in einem begrenzten Ausmaß in Richtung der Längsachse der Vorrichtung beweglich gelagert ist und
  • b) unterhalb des Abtrenngeräts ein Schlitten mit Halterungen für eine Doppelbodenplatte angeordnet ist, der quer zum Trennmesser des Abtrenngeräts bzw. parallel zur Längsachse der Vorrichtung motorisch hin- und herverfahrbar ist.
According to the invention the above object is achieved in that
  • a) the separating device forms part of a device for automatically separating the coverings and is pivotally or adjustably attached to a mounting plate about a horizontal axis, which is cushioned to a limited extent in a horizontal or approximately horizontal plane on a transversely arranged frame part of the device is movably mounted in the direction of the longitudinal axis of the device and
  • b) a carriage with brackets for a raised floor plate is arranged below the separating device and can be moved back and forth by motor transversely to the separating knife of the separating device or parallel to the longitudinal axis of the device.

Mit einer solchen Vorrichtung können Deckbeläge von Doppelbodenplatten einfach und schnell von dem tragenden Plattenteil entfernt bzw. abgeschält werden, ohne daß die Gefahr besteht, daß der tragende Plattenteil, insbesondere im Kanten- und Randbereich beschädigt wird. Die schwenkbare Lagerung des Abtrenngeräts um eine horizontale Achse ermöglicht eine optimale Einstellung des Arbeitswinkel des Trennmessers und aufgrund der erfindungsgemäßen Lagerung der das Abtrenngerät tragenden Aufnahmeplatte am Rahmen der Vorrichtung wird die Übertragung von Schwingungen vom Abtrenngerät auf den erwähnten Rahmen auf einen zulässigen Wert gehalten. Man braucht zum Abtrennen eines Deckbelages lediglich die betreffende Doppelbodenplatte in ihre Halterungen einlegen und darin gegebenenfalls zu verspannen sowie die Vorrichtung in Betrieb zu setzen, wobei im Zuge der Schlittenbewegung unter dem Abtrenngerät vorbei, dessen Trennmesser den betreffenden Deckbelag vom tragenden Plattenteil abtrennt bzw. abschält, was nur relativ wenig Zeit beansprucht. Der Abtrennvorgang erfolgt derart sauber, daß die tragenden Plattenteile sofort wieder mit einem neuen Deckbelag versehen werden können. Die erfindungsgemäße Vorrichtung ist daher speziell auch für den Baustelleneinsatz geeignet. Denn die Sanierung von Doppelböden vor ort muß wegen der damit verbundenen vorübergehenden Stillegung von Gebäuderäumen in kürzester Zeit durchführbar sein.With such a device, coverings of raised floor panels can be removed and peeled off easily and quickly from the load-bearing plate part without the risk that the load-bearing plate part is damaged, in particular in the edge and edge area. The pivotable mounting of the separating device about a horizontal axis enables the working angle of the separating knife to be optimally adjusted, and due to the mounting according to the invention of the mounting plate carrying the separating device on the frame of the device, the transmission of vibrations from the separating device to the above-mentioned frame is kept to a permissible value. You only need to remove a cover Insert the double floor slab in question into its holders and, if necessary, clamp it in it and put the device into operation, passing under the separating device in the course of the slide movement, the separating knife of which separates or peels off the covering in question from the supporting plate part, which takes up relatively little time. The separation process is carried out so cleanly that the load-bearing plate parts can immediately be provided with a new cover. The device according to the invention is therefore particularly suitable for use on construction sites. Because the renovation of double floors on site must be feasible in a very short time due to the associated temporary decommissioning of building rooms.

Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor. So ist es zweckmäßig, wenn an dem Schlitten ein Auflage- und Führungsbalken für das Trennmesser vorgesehen ist, der das Trennmesser am Anfang einer Vorschubbewegung des Schlittens auf das zum Abtrennen eines Deckbelages erforderliche Niveau hält bzw. führt. Dieser Auflage- und Führungsbalken für das Trennmesser stellt ein zusätzliches Sicherheitsmerkmal der erfindungsgemäßen Vorrichtung dar, durch welches gewährleistet ist, daß die Angriffstelle des Trennmessers zu Beginn eines Abtrennvorgangs auf dem richtigen Niveau liegt, also zwischen Unterseite Deckbelag und Oberseite des tragenden Plattenteils einer Doppelbodenplatte.Embodiments of the invention emerge from the subclaims. It is expedient if a support and guide bar for the cutting knife is provided on the slide, which holds or guides the cutting knife at the start of a feed movement of the slide to the level required for cutting off a covering. This support and guide bar for the cutting knife represents an additional security feature of the device according to the invention, which ensures that the point of attack of the cutting knife at the start of a separation process is at the correct level, i.e. between the underside of the covering and the top of the load-bearing plate part of a raised floor plate.

Nach noch einer weiteren Ausgestaltung der Erfindung ist die Aufnahmeplatte höhenverstellbar an dem quer­verlaufenden Rahmenteil der Vorrichtung angeordnet. Dadurch kann auf einfache Weise die Arbeitshöhe des Abtrenngeräts zur Anpassung an unterschiedlich hohe Doppelbodenplattentypen verändert werden, und zwar bei gleichbleibenden fixierten Arbeitswinkel des Trennmessers.According to yet another embodiment of the invention, the mounting plate is arranged on the transverse frame part of the device in an adjustable manner. As a result, the working height of the separating device can be changed in a simple manner, in order to adapt to different types of raised floor panels constant fixed working angle of the cutting knife.

Die Unteransprüche 4, 5 und 6 sind auf eine baulich besonders einfache, zuverlässige Lagerung des Abtrenngerätes am Rahmen der Vorrichtung gerichtet.The sub-claims 4, 5 and 6 are directed to a structurally particularly simple, reliable storage of the separation device on the frame of the device.

Wenn nach noch einer weiteren Ausgestaltung der Erfindung mehrere Abtrenngeräte seitlich nebeneinander über eigene Aufnahmeplatten an dem quer angeordneten Rahmenteil gelagert sind, können vorteilhaft Trennmesser mit entsprechend kleiner Arbeitsbreite verwendet werden, die wiederum mit entsprechend schwächeren Motorleistungen auskommen. Die Lagerung solchere Abtrenngeräte am quer­verlaufenden Rahmenteil der Vorrichtung wird dadurch auch entsprechend einfacher.If, according to yet another embodiment of the invention, a plurality of cut-off devices are mounted laterally next to one another via their own mounting plates on the transversely arranged frame part, cut-off knives with a correspondingly small working width can advantageously be used, which in turn manage with correspondingly weaker engine outputs. The storage of such separation devices on the transverse frame part of the device is also correspondingly easier.

Nach noch einer weiteren, bevorzugten Ausführungsform der Erfindung sind drei Abtrenngeräte vorgesehen, von welchen das mittlere gegenüber den beiden äußeren Abtrenngeräten in Achsrichtung der Vorrichtung versetzt, z.B. vorspringend angeordnet ist. Diese Version eignet sich speziell für die Bearbeitung von Doppelbodenplatten mit einem Grundriß von 600 x 600 mm, wobei die Arbeitsbreite der Trennmesser jeweils etwas mehr als 200 mm beträgt. Dadurch, daß das mittlere der drei Abtrenngeräte gegenüber den beiden anderen in Achsrichtung der Vorrichtung versetzt angeordnet ist, vermeidet man zuverlässig eine seitliche Kollision der im Betrieb oszillierenden Trennmesser.According to yet another preferred embodiment of the invention, three separation devices are provided, of which the middle one is offset in relation to the two outer separation devices in the axial direction of the device, e.g. is arranged in a projecting manner. This version is particularly suitable for processing raised floor panels with a floor plan of 600 x 600 mm, whereby the working width of the separating knives is slightly more than 200 mm. The fact that the middle of the three separating devices is offset from the other two in the axial direction of the device reliably prevents a lateral collision of the separating knives which oscillate during operation.

Eine bevorzugte, gewichtssparende Ausführung des die Doppelbodenplatte aufnehmenden Schlittens wird erreicht, wenn dieser im wesentlichen aus einem rahmenförmigen Teil besteht, an dessen Ecken die Halterungen für die Doppelbodenplatte angeordnet sind, wobei der Schlitten zweckmäßig auf zwei Führungsstangen am Rahmen der Vorrichtung hin- und herverfahrbar gelagert ist.A preferred, weight-saving design of the slide receiving the raised floor plate is achieved if it consists essentially of a frame-shaped part, at the corners of which the holders for the Raised floor plate are arranged, wherein the carriage is expediently mounted on two guide rods on the frame of the device.

Ein baulich einfacher und gleichwohl rubuster Antrieb des Schlittens wird dadurch erreicht, daß an diesem eine auf einer Gewindespindel sitzende Laufmutter befestigt ist, und die Gewindespindel am Rahmen der Vorrichtung drehbeweglich, jedoch axial fest gelagert und abwechselnd in beiden Drehrichtungen motorisch antreibbar ist.A structurally simple and nevertheless robust drive of the slide is achieved in that a running nut seated on a threaded spindle is attached to it, and the threaded spindle on the frame of the device is rotatable, but axially fixed and alternately motor-driven in both directions of rotation.

Um bei Betriebsstörungen, z. B. bei zwischen Deckbelag und tragendem Plattenteil verklemmten Trennmesser eine Beschädigung des oder der Abtrenngeräte zu vermeiden, ist vorzugsweise in dem Antriebszug zwischen Antriebsmotor und Gewindespindel eine Rutschkupplung eingebaut.To in case of malfunctions, e.g. B. to prevent damage to the cutting device or cutters between the covering and the supporting plate part, a slip clutch is preferably installed in the drive train between the drive motor and the threaded spindle.

Nach noch einer weiteren Ausgestaltung der Erfindung wird die Gewindespindel zum Schutz gegen Verschmutzung zweckmäßig von einer Kegelfeder umhüllt.According to yet another embodiment of the invention, the threaded spindle is expediently encased by a conical spring for protection against contamination.

Die erfindungsgemäße Vorrichtung ist zum selbsttätigen Abtrennen der meisten üblichen Deckbeläge von Doppelbodenplatten geeignet, insbesondere von Teppichböden und PVC-Belägen oder dergleichen.The device according to the invention is suitable for automatically separating most of the usual coverings from raised floor panels, in particular from carpets and PVC coverings or the like.

Die Erfindung wird anschließend anhand von Zeichnungen eines Ausführungsbeispiels erläutert. Es zeigen:

  • Fig. 2 eine schematische Draufsicht der in Fig. 1 gezeigten Vorrichtung, wobei die auf dem in seiner Ausgangsstellung befindlichen Schlitten aufgelagerte Doppelbodenplatte teilweise aufgebrochen ist, um die Lagerung der Gewindespindel für den Antrieb des Schlittens deutlicher zu zeigen.
The invention is subsequently explained on the basis of drawings of an exemplary embodiment. Show it:
  • Fig. 1 is a schematic side view of a device according to the invention for automatically separating the coverings from double floor panels, the slide with part of an already processed double floor panel in its left edge position shown in dash-dotted lines is, that is, before the start of its return to its right starting position, while in the right part of this figure the beginning of a separation process for a cover is shown in full lines;
  • Fig. 2 is a schematic plan view of the device shown in Fig. 1, wherein the double bottom plate supported on the carriage in its initial position has been partially broken open to show the storage of the threaded spindle for driving the carriage more clearly.

Mit der Bezugszahl 10 ist in Fig. 1 eine Doppelbodenplatte bezeichnet, deren Deckbelag 12, z. B. ein Teppichboden vom tragenden Plattenteil 11 entfernt bzw. abgetrennt werden soll. Solche Doppelbodenplatten 10 werden bekanntlich auf Fußstützen in Abstand von einem Rohboden aufgelagert, so daß zwischen den aufgeständerten Doppelbodenplatten und dem Rohboden ein Raum zur Aufnahme verschiedener Installationsleitungen vorhanden ist. Die Entfernung der Deckbeläge 12 von den tragenden Plattenteilen 11 kann aus verschiedenen Gründen erforderlich sein, in der Regel ist hierfür jedoch ein Verschleiß der Deckbeläge 12 ausschlaggebend. Die Abtrennung bzw. Abschälung des Deckbelags 12 vom tragenden Plattenteil 11 erfolgt völlig selbsttätig mittels einer Vorrichtung 13. Es sei schon an dieser Stelle betont, daß die Vorrichtung 13 auch zum Abtrennen von Deckbelägen anderer relativ kleinformatiger Bodenplatten geeignet ist, z. B. von Platten sog. Montageböden.The reference number 10 in Fig. 1 denotes a raised floor panel, the cover 12, z. B. a carpet from the supporting plate part 11 to be removed or separated. Such raised floor panels 10 are known to be supported on footrests at a distance from an unfinished floor, so that a space for accommodating various installation lines is present between the raised raised floor panels and the unfinished floor. The removal of the coverings 12 from the load-bearing plate parts 11 may be necessary for various reasons, but as a rule wear of the coverings 12 is decisive for this. The separation or peeling of the cover 12 from the load-bearing plate part 11 takes place completely automatically by means of a device 13. It should be emphasized at this point that the device 13 is also suitable for separating coverings from other relatively small-sized floor plates, for. B. of plates so-called assembly floors.

Die Vorrichtung 13 weist einen tragenden Rahmen 14 aus zahlreichen, untereinander verbundenen Vierkantrohren auf. Auf dem Rahmen 14 stützt sich über zwei stehend angeordnete Seitenteile 16 ein quer zur Längesachse der Vorrichtung 13 verlaufender Rahmenteil 15 ab. Der Rahmenteil 15 bildet mit seinen beiden Seitenteilen 16 eine portalartige Tragkonstruktion für beispielsweise drei gleichartige Abtrenngeräte 17, die jeweils ein elektromotorisch angetriebenes oszillierendes Trennmesser 18 aufweisen. Die Aufhängung bzw. Lagerung jedes der drei Abtrenngeräte 17 an dem Rahmenteil 15 ist gleichartig und es wird daher nachstehend nur eine detailliert beschrieben. Es wird jedoch schon an dieser Stelle betont, daß das mittlere der drei Abtrenngeräte 17 gegenüber den beiden äußeren Abtrenngeräten 17 in Richtung der Längsachse der Vorrichtung 13 versetzt bzw. vorspringend angeordnet ist, um eine Kollision der im Betrieb oszillierenden Trennmesser 18 der drei Abtrenngeräte 17 zu vermeiden. Wie aus Fig. 2 hervorgeht, können sich aufgrund der obigen Anordnung die Arbeitsbahnen der Trennmesser 18 seitlich etwas überlappen. Die in den Fig. 1 und 2 gezeigte Doppelbodenplatte 10 hat z. B. einen Grundriß von 600 x 600 mm und die Arbeitsbreite der Trennmesser 18 beträgt jeweils 210 mm. Der Deckbelag 12 kann daher bei in Betrieb befindlicher Vorrichtung 13 von den drei Abtrenngeräten 17 in einem Arbeitsgang von dem tragenden Plattenteil 11 der Doppelbodenplatte 10 abgetrennt bzw. abgeschält werden, was noch ausführlich erläutert wird.The device 13 has a supporting frame 14 numerous, interconnected square tubes. A frame part 15, which runs transversely to the longitudinal axis of the device 13, is supported on the frame 14 via two standing side parts 16. With its two side parts 16, the frame part 15 forms a portal-like supporting structure for, for example, three similar separating devices 17, each of which has an oscillating separating knife 18 driven by an electric motor. The suspension or storage of each of the three separation devices 17 on the frame part 15 is of the same type and therefore only one is described in detail below. However, it is already emphasized at this point that the middle of the three separating devices 17 is offset or arranged in a projecting manner in relation to the two outer separating devices 17 in the direction of the longitudinal axis of the device 13 in order to prevent the cutting blades 18 of the three separating devices 17, which oscillate during operation, from colliding avoid. As can be seen from FIG. 2, the working paths of the separating knives 18 can overlap somewhat laterally due to the above arrangement. The raised floor plate 10 shown in FIGS. 1 and 2 has, for. B. a floor plan of 600 x 600 mm and the working width of the cutting knife 18 is 210 mm. The cover 12 can therefore be separated or peeled off from the three separating devices 17 in one operation from the supporting plate part 11 of the raised floor plate 10 when the device 13 is in operation, which will be explained in detail.

Jedes Abtrenngerät 17 ist um eine horizontale Achse 19 in einem U-förmigen Halter 20 schwenkbar bzw. einstellbar gelagert, um den Arbeitswinkel des Trennmessers 18 entsprechend den jeweiligen Anforderungen einstellen zu können, die durch die Art des Deckbelags 12 und des tragenden Plattenteils 11 vorgegeben sind. In seiner Einstellage wird jedes Abtrenngerät 17 durch nicht gezeigte Schrauben an dem U-förmigen Halter 20 fixiert. Der Halter 20 ist an einer Aufnahmeplatte 21 starr befestigt, z. B. angeschraubt. Die rechteckförmige Aufnahmeplatte 21 wird von vier Augenschrauben 22 getragen, die mittels Bolzen 23 an den vier Ecken der Aufnahmeplatte 21 angelenkt sind. Die Augenschrauben 22 erstrecken sich mit seitlichem Spiel durch Bohrungen 24 in dem Rahmenteil 15 und stützen sich über Muttern 25 an der Oberseite des Rahmenteils 15 ab. Mit 26 sind entsprechende Muttersicherungen bezeichnet.Each separating device 17 is pivotably or adjustably mounted about a horizontal axis 19 in a U-shaped holder 20 in order to be able to adjust the working angle of the separating knife 18 in accordance with the respective requirements which are predetermined by the type of cover layer 12 and the supporting plate part 11 . In its In the setting position, each separating device 17 is fixed to the U-shaped holder 20 by screws, not shown. The holder 20 is rigidly attached to a mounting plate 21, for. B. screwed. The rectangular receiving plate 21 is supported by four eyebolts 22, which are hinged to the four corners of the receiving plate 21 by means of bolts 23. The eyebolts 22 extend with lateral play through bores 24 in the frame part 15 and are supported by nuts 25 on the upper side of the frame part 15. Corresponding nut locks are designated by 26.

Zwischen der Mitte jeder Aufnahmeplatte 21 und dem Rahmenteil 15 ist eine Druckfeder 27 eingespannt. An der Oberseite der Aufnahmeplatte 21 greifen vier symmetrisch am Rahmenteil 15 angeordnete Schrauben 28 an. Die unteren Enden dieser in ihren Einstellagen gesicherten Schrauben 28 bilden Widerlager für die Aufnahmeplatte 21, wenn die Muttern 25 angezogen werden. Aus obigem geht hervor, daß die Aufnahmeplatte 21 in einer horizontalen oder etwa horizontalen Ebene abgefedert in einem begrenzten Ausmaß parallel zur Längsachse der Vorrichtung 13 beweglich gelagert werden kann, was erforderlich ist, um die Übertragung von durch die Abtrenngeräte 17 erzeugten Schwingungen auf den Rahmen 14 auf einem akzeptablen Wert zu halten. Außerdem sind aufgrund obiger Anordnung die Aufnahmeplatten 21 der drei Abtrenngeräte 17 am Rahmenteil 15 höhenverstellbar gelagert, wodurch eine Anpassung der Vorrichtung 13 an Doppelbodenplatten 10 unterschiedlicher Bauhöhen möglich ist.A compression spring 27 is clamped between the center of each mounting plate 21 and the frame part 15. Four screws 28 arranged symmetrically on the frame part 15 engage on the upper side of the receiving plate 21. The lower ends of these screws 28 secured in their setting positions form abutments for the receiving plate 21 when the nuts 25 are tightened. From the above it can be seen that the mounting plate 21 can be mounted in a horizontal or roughly horizontal, cushioned manner, to a limited extent, parallel to the longitudinal axis of the device 13, which is necessary in order to transmit vibrations generated by the separating devices 17 to the frame 14 to keep it at an acceptable level. In addition, due to the above arrangement, the mounting plates 21 of the three separating devices 17 are mounted on the frame part 15 so that they can be adjusted in height, so that the device 13 can be adapted to raised floor plates 10 of different heights.

Unterhalb der drei Abtrenngeräte 17 ist ein Schlitten 29 quer zu den Trennmessern 18 bzw. parallel zur Längsachse der Vorrichtung 13 motorisch hin- und herverfahrbar auf dem Rahmen 14 gelagert. Der Schlitten 29 weist ein rahmenförmiges Teil 30 auf, an dessen vier Ecken winkelförmige Halterungen 31 für die Doppelbodenplatte 10 befestigt sind. Die Doppelbodenplatte 10 ruht mit ihren Eckenbereichen auf den Köpfen von durch Konternmuttern arretierbaren Schrauben 32 an den Halterungen 31, die zur Höhenjustierung der Doppelbodenplatte 10 dienen. Zwischen den zwei gem. Fig. 1 und 2 linken, einander gegenüberliegenden Halterungen 31 erstreckt sich ein Auflage- und Führungsbalken 33 für die drei Trennmesser 18. Der Auflage- und Führungsbalken 33 kann auch direkt über Stützen am rahmenförmigen Teil 30 befestigt sein. Dieser Auflage- und Führungsbalken 33 gewährleistet am Anfang einer Vorschubbewegung des Schlittens 29 (gem. Fig 1 und 2 in Pfeilrichtung nach links), daß sich die Abtrennmesser 18 auf das zum Abtrennen des Deckbelages 12 erforderliche Niveau befinden und er verhindert damit gleichzeitig zuverlässig eine Beschädigung des Kanten- oder Randbereichs des tragenden Plattenteils 11 durch die Trennmesser 18, während diese ihre oszillierenden Bewegungen ausführen.Below the three separating devices 17, a carriage 29 is mounted on the frame 14 so as to be able to be moved back and forth by a motor transversely to the separating blades 18 or parallel to the longitudinal axis of the device 13. The carriage 29 has a frame-shaped part 30, at the four corners of which angular brackets 31 for the raised floor plate 10 are attached. The double base plate 10 rests with its corner areas on the heads of screws 32 which can be locked by lock nuts on the brackets 31, which serve for height adjustment of the double base plate 10. Between the two acc. 1 and 2 left, opposite brackets 31 extends a support and guide bar 33 for the three separating knives 18. The support and guide bar 33 can also be attached directly to the frame-shaped part 30 via supports. This support and guide bar 33 ensures at the start of a feed movement of the slide 29 (according to FIGS. 1 and 2 in the direction of the arrow to the left) that the separating knives 18 are at the level required for separating the cover layer 12 and at the same time reliably prevents damage of the edge or edge area of the supporting plate part 11 by the separating knife 18 while they are performing their oscillating movements.

Der rahmenförmige Teil 30 des Schlittens 29 ist mittels vier Lager 34 auf zwei Führungsstangen 35 gelagert. Die Führungsstangen 35 erstrecken sich parallel zur Längsachse der Vorrichtung 13 und sind mit ihren Enden in Schienen 36 befestigt, die ihrerseits am Rahmen 14 festgemacht, z.B. angeschraubt sind.The frame-shaped part 30 of the slide 29 is mounted on two guide rods 35 by means of four bearings 34. The guide rods 35 extend parallel to the longitudinal axis of the device 13 and are fixed at their ends in rails 36, which in turn are attached to the frame 14, e.g. are screwed on.

Mit dem rahmenförmigen Teil 30 des Schlittens 29 ist über einem Mitnehmer 37 eine Laufmutter 38 verbunden, die auf einer Gewindespindel 39 sitzt. Die Gewindespindel 39 ist an ihren Enden in Wälzlager 40 gelagert, welche an der einen Schiene 36 bzw. an einem Teil 41 des Rahmens 14 befestigt sind. Die Gewindespindel 39 ist somit am Rahmen 14 drehbeweglich, jedoch axial fest gelagert. Ihr Antrieb zur Erzeugung einer Vorschubbewegung des Schlittens 29 erfolgt durch einen am Rahmen 14 befestigten Verstellgetriebemotor 42, dessen treibendes Ritzel 43 z.B. über eine Antriebskette 44 mit einem Zahnrad 45 verbunden ist, welches ein Teil einer Rutschkupplung 46 bildet, die mit der Gewindespindel 39 antriebsmäßig verbunden ist. Die Rutschkupplung 46 bildet ein Sicherungselement für den Fall, daß es zu einer Betriebsstörung beim Abtrennen des Deckbelags 12 vom tragenden Plattenteil 11 kommt. Bei eingeschaltetem Verstellgetriebemotor 42 wird über das Ritzel 43, die Antriebskette 44, das Zahnrad 45 und die Rutschkupplung 46 die Gewindespindel 39 so gedreht, daß sich die Laufmutter 38 und damit der Schlitten 29 mit der eingelegten Doppelbodenplatte 10 gem. Fig. 1 und 2 nach links bewegen. Die Vorschubgeschwindigkeit des Schlittens 29 ist dabei so gewählt, daß die drei Trennmesser 18 der nunmehr gleichfalls eingeschalteten Abtrenngeräte 17 den Deckbelag 12 in einem Arbeitsgang vom tragenden Plattenteil 11 abtrennen bzw. abschälen. Der Anfang dieses Abtrennvorganges ist in Fig. 1 angedeutet. Wenn der Schlitten 29 seine in Fig. 1 links in strichpunktierten Linien gezeigte Endstellung erreicht hat, ist der Deckbelag 12 vollständig vom Plattenteil 11 entfernt und er kann dann von Hand oder auch durch nicht gezeigte Auswerfereinrichtungen aus der Vorrichtung entfernt werden. Sobald der Schlitten 29 seine gem. Fig. 1 linke Endstellung erreicht hat, wird der Verstellgetriebemotor 42 z.B. über nicht gezeigte Endschalter abgeschaltet und ein weiterer Antriebsmotor 47 eingeschaltet, der die Rückführung des Schlittens 29 mit dem Plattenteil 11 in die in Fig. 1 rechts gezeigte Ausgangsstellung bewirkt. Diese Rückführung des Schlittens 29 mit dem Plattenteil 11 in die Ausgangsstellung erfolgt vorzugsweise mit einer wesentlich höheren Geschwindigkeit als der Vorschub des Schlittens 29. Der Antriebsmotor 47 ist mit seinem Antriebsritzel 48 über eine Antriebskette 49 mit einem Zahnrad 50 einer Rutschkupplung 51 antriebsmäßig verbunden. Die Rutschkupplung 51 sitzt auf der Gewindespindel 39 und dient gleichfalls als Sicherungselement, welches im Falle einer Betriebsstörung in Funktion tritt.A running nut 38 is connected to the frame-shaped part 30 of the slide 29 via a driver 37, which nut sits on a threaded spindle 39. The threaded spindle 39 is supported at its ends in roller bearings 40 which are fastened to one rail 36 or to part 41 of the frame 14. The threaded spindle 39 is thus rotatable on the frame 14, but axially fixed. Your drive to generate a feed movement of the carriage 29 is carried out by a variable-speed gear motor 42 fastened to the frame 14, the driving pinion 43 of which is connected, for example, via a drive chain 44 to a toothed wheel 45, which forms part of a slip clutch 46 which is connected to the threaded spindle 39 in terms of drive. The slip clutch 46 forms a securing element in the event that there is a malfunction when the cover 12 is separated from the load-bearing plate part 11. When the variable-speed gear motor 42 is switched on, the threaded spindle 39 is rotated via the pinion 43, the drive chain 44, the gear 45 and the slip clutch 46 in such a way that the running nut 38 and thus the slide 29 with the inserted double floor plate 10 according to FIG. 1 and 2 move to the left. The feed speed of the carriage 29 is selected so that the three cutting knives 18 of the cutting devices 17, which are now also switched on, cut off or peel off the covering 12 from the supporting plate part 11 in one operation. The beginning of this separation process is indicated in Fig. 1. When the carriage 29 has reached its end position shown in dash-dotted lines on the left in FIG. 1, the cover layer 12 is completely removed from the plate part 11 and can then be removed from the device by hand or also by ejector devices (not shown). As soon as the carriage 29 its gem. 1 has reached the left end position, the variable-speed gear motor 42 is switched off, for example via limit switches (not shown), and a further drive motor 47 is switched on, which causes the carriage 29 with the plate part 11 to be returned to the starting position shown on the right in FIG. 1. This return of the carriage 29 with the plate part 11 into the starting position is preferably carried out with a much higher speed than the feed of the slide 29. The drive motor 47 is connected with its drive pinion 48 via a drive chain 49 to a gear 50 of a slip clutch 51. The slip clutch 51 sits on the threaded spindle 39 and also serves as a securing element, which comes into operation in the event of a malfunction.

Wenn der Antriebsmotor 47 durch entsprechende Drehung der Gewindespindel 39 den Schlitten 29 wieder zurück in die in Fig. 1 gezeigte Ausgangsstellung bewegt hat, wird der Antriebsmotor 47 z. B. durch einen nicht gezeigte Endschalter wieder abgeschaltet und der tragende Plattenteil 11 kann nun aus den Halterungen 31 des Schlittens 29 herausgehoben und aus der Vorrichtung 13 entfernt werden. Die Vorrichtung 13 ist nun für einen neuen Arbeitsgang einsatzbereit.When the drive motor 47 has moved the slide 29 back into the starting position shown in FIG. 1 by corresponding rotation of the threaded spindle 39, the drive motor 47 is driven e.g. B. switched off again by a limit switch, not shown, and the supporting plate part 11 can now be lifted out of the brackets 31 of the carriage 29 and removed from the device 13. The device 13 is now ready for a new operation.

Mit den Bezugzahlen 52 und 53 sind in strichpunktierten Linien zwei Abdeckhauben für die Vorrichtung 13 angedeutet, die zum Öffnen der Vorrichtung 13 einfach abgeklappt werden können.The reference numbers 52 and 53 indicate two cover hoods for the device 13 in dash-dotted lines, which can simply be folded down to open the device 13.

Die Gewindespindel 39 kann durch eine zwischen dem Mitnehmer 37 und der Rutschkupplung 51 eingespannte Kegelfeder umhüllt sein, welche die Gewindespindel 39 gegen Verschmutzung schützt.The threaded spindle 39 can be encased by a conical spring clamped between the driver 37 and the slip clutch 51, which protects the threaded spindle 39 against contamination.

Auf einen der zwei beim Ausführungsbeispiel vorgesehenen Antriebsmotore 42, 47 für die Gewindespindel 39 kann verzichtet werden, wenn ein solcher vorgesehen wird, der abwechselnd in zwei Drehrichtungen aktivierbar ist.One of the two drive motors 42, 47 provided in the exemplary embodiment for the threaded spindle 39 can be dispensed with if one is provided which can be activated alternately in two directions of rotation.
