Das erste Ausführungsbeispiel, die Austragvorrichtung 1, enthält zwei Leimzylinder 2 und 3 sowie eine Leimleiste 4 und eine Druckluftzuführeinrichtung 5. Die Leimzylinder 2 und 3 dienen der Aufnahme von Leimbeuteln, hier nicht eingezeichnet, und weisen zum Austragen einen Kolben 6 auf, der einen Dichtungsring 7 aufweist, damit die Druckluft nicht um den Kolben abfliesst und damit den Druck verringert, und ein nasenförmiges Frontteil 8, dessen Form dem trichterförmigen Einlass 9 der Düse 10 entspricht.The first embodiment, the discharge device 1, contains two glue cylinders 2 and 3 as well as a glue bar 4 and a compressed air supply device 5. The glue cylinders 2 and 3 serve to hold glue bags, not shown here, and have a piston 6 for discharge, which has a sealing ring 7 so that the compressed air does not flow around the piston and thus the pressure reduced, and a nose-shaped front part 8, the shape of which corresponds to the funnel-shaped inlet 9 of the nozzle 10.
Zwischen dem Zylinderauslass 12 und der Leimleiste ist einen Düse 10 angeordnet, die zu einem Hohlraum 16 führt, von dem aus Kanäle 11a - Hg angeordnet sind, die in Austragöffnungen 14a - 14g in der Leimleiste münden. Der Hohlraum 16 gewährleistet, dass der Leim gleichmässig an alle Austragöffnungen geleitet wird, wodurch ein gleichmässiges Auftragen ermöglicht wird. DieBetween the cylinder outlet 12 and the glue bar, a nozzle 10 is arranged, which leads to a cavity 16, from which channels 11a-Hg are arranged, which open into discharge openings 14a-14g in the glue bar. The cavity 16 ensures that the glue is evenly conducted to all discharge openings, which enables a uniform application. The
Austragöffnungen und deren Abstände untereinander sind den verschiedenen Parkettriemenbreiten angepasst.Discharge openings and their spacing from one another are adapted to the different parquet belt widths.
Die Leimleiste 4 besteht aus zwei zueinander komplementären Teilen 4A und 4B, wobei beide Teile durch Zylinderschrauben 13 miteinander verbunden werden. Die Leimausflussmenge wird durch die Grosse und Anzahl der Austragöffnungen, der Fahrgeschwindigkeit sowie durch den Systemdruck bestimmt und geregelt .The glue strip 4 consists of two mutually complementary parts 4A and 4B, both parts being connected to one another by cylinder screws 13. The amount of glue discharged is determined and regulated by the size and number of discharge openings, the driving speed and the system pressure.
Die Düse ist in der Leimleiste 4 eingelassen und kann nach dem Zusammenschrauben der zweiteiligen Leimleiste nicht mehr herausfallen. Die Leimleiste wird mit den Düsen mittels einer Mutter 12M am Leimzylinder befestigt.The nozzle is embedded in the glue strip 4 and can no longer fall out after the two-part glue strip has been screwed together. The glue strip is attached to the glue cylinder with the nozzles using a nut 12M.
Die gesamte Leimleiste ist mit einem leimabweisenden Kunststoff beschichtet, beispielsweise mit Teflon®. Dadurch bleibt der Leim nach dem Aushärten nicht daran haften und kann leicht entfernt werden, wodurch ein schnelles Reinigen der Leimleiste erfolgen kann, Damit beim Einsatz derThe entire glue strip is coated with a glue-repellent plastic, for example with Teflon®. As a result, the glue does not stick to it after curing and can be easily removed, which means that the glue strip can be cleaned quickly, so that when the
Vorrichtung die Leimleiste den Boden nicht berührt und somit die Teflonschicht nicht beschädigt wird, befinden sich an beiden Enden der Leimleiste Rollen 15, die beispielsweise über ein Rillenkugellager an der Leiste befestigt sind. Die beiden Leimzylinder werden durch zwei Brillen 17 und 18 zusammengehalten, wobei die Brillen den verschiedenen Leimleisten angepasst oder je nach Leimleistentyp ausgewechselt werden können.If the glue strip does not touch the floor and the teflon layer is not damaged, there are rollers 15 on both ends of the glue strip, which are attached to the strip, for example, via a grooved ball bearing. The two glue cylinders are through two glasses 17 and 18 held together, whereby the glasses can be adapted to the different glue strips or exchanged depending on the type of glue strip.
Die beiden Ausführungsbeispiele gemäss den Figuren 1 bis 3 und 4 bis 6 werden mittels Druckluft betrieben. Die externe Druckluftzufuhr erfolgt über einen Zuleitungsschlauch 19, der über eine Verbindung 20 mit einem Handgriff 21 verbunden ist, von dem aus die interne Druckluft auf die verschiedenen Leimzylinder geleitet wird. Der Handgriff 21 ist mittels einem Klemmring 22 am Leimzylinder 2 befestigt und weist ein Knopftastenventil 23 auf, das von der externen Speiseleitung 19 beaufschlagt wird und die Druckluft dosiert an die Ableitung 24 verteilen kann.The two exemplary embodiments according to FIGS. 1 to 3 and 4 to 6 are operated by means of compressed air. The external compressed air supply takes place via a supply hose 19, which is connected via a connection 20 to a handle 21, from which the internal compressed air is directed to the various glue cylinders. The handle 21 is fastened to the glue cylinder 2 by means of a clamping ring 22 and has a button button valve 23 which is acted upon by the external feed line 19 and which can distribute the compressed air in a metered manner to the discharge line 24.
Die Leitung 24 führt auf einen Verteiler 25, hier ein Doppelverteiler, von dem aus die Druckluft auf die Leimzylinder 2 und 3 geführt wird. Vom Verteiler 25 führt eine Leitung 26 zum Eingang eines Schnellentlüftungsventils 27. Das Schnellentlüftungsventil 27 enthält eine Membrane 28, einen Membrandeckel 29 sowie einen Rohrdeckel 30. Das Ventil mit dem Einlass wird mittels einer Rohrmutter 31 am Leimzylinder befestigt.The line 24 leads to a distributor 25, here a double distributor, from which the compressed air is guided to the glue cylinders 2 and 3. A line 26 leads from the distributor 25 to the inlet of a quick exhaust valve 27. The quick exhaust valve 27 contains a membrane 28, a membrane cover 29 and a pipe cover 30. The valve with the inlet is attached to the glue cylinder by means of a pipe nut 31.
Das Schnellentlüftungsventil gewährleistet, dass beim Loslassen des Knopftastenventils der Druckaufbau im Leimzylinder sehr schnell abfällt. Dies verhindert ein Nachdrücken des Leims aus der Leimleiste. Aus Sicherheitsgründen ist das Schnellentlüftungsventil 27 mit dem Kolben 6 über eine Schnurverbindung verbunden, um beim unbeabsichtigten Betätigen des Knopftastenventils ein Ausstossen des Kolbens zu verhindern.The quick exhaust valve ensures that the pressure build-up in the glue cylinder drops very quickly when the button button valve is released. This prevents the glue from being pressed out of the glue strip. For safety reasons, the quick exhaust valve 27 is connected to the piston 6 via a cord connection in order to prevent the piston from being ejected when the button button valve is actuated unintentionally.
Zum Füllen des Leimzylinders wird der Kolben in Richtung Schnellentlüftungsventil 27 verschoben. Nach dem Einbringen des Leimbeutels wird die Mutter 12M am Leimzylinder-Rohr befestigt. Damit ist das Gerät einsatzbereit. Auf der Zeichnung sind ferner noch zwei Dichtungsringe 32 und 33 ersichtlich.To fill the glue cylinder, the piston is moved in the direction of the quick exhaust valve 27. After insertion of the glue bag, the nut 12M is attached to the glue cylinder tube. The device is now ready for use. Two sealing rings 32 and 33 can also be seen in the drawing.
In Figur 4 ist eine Austragvorrichtung 34 angegeben, die zusätzlich zu den beiden Leimzylindern 2 und 3 einen dritten Leimzylinder 35 aufweist, wobei die Leimleiste 36 demgemäss drei Düsen 10 aufweist, die in den Hohlraum 16 münden von dem aus jedoch je vier Kanäle 37a, 37b, 37c und 37d abzweigen und die Leimleiste entsprechend drei mal vier Austragöffnungen 38a, 38b, 38c und 38d aufweist. Die Leimleiste weist dieselben Rollen 15 auf wie die Leimleiste für zwei Leimzylinder und hat den entsprechend gleichen Aufbau.FIG. 4 shows a discharge device 34 which, in addition to the two glue cylinders 2 and 3, has a third glue cylinder 35, the glue strip 36 accordingly having three nozzles 10 which open into the cavity 16 from which four channels 37a, 37b respectively , 37c and 37d branch off and the glue strip correspondingly has three times four discharge openings 38a, 38b, 38c and 38d. The glue strip has the same rollers 15 as the glue strip for two glue cylinders and has the same structure.
Die Druckluftzufuhr erfolgt gleich wie beim ersten Ausführungsbeispiel, wobei der Handgriff 31 am mittleren Zylinder 2 angebracht ist und anstatt eines Doppelverteilers 25 ein Dreifachverteiler 38 vorhanden ist, so dass die Druckluft sowohl auf den Leimzylinder 2 als auch via Leitungen 26 und 57 auf die beiden anderen Leimzylinder 3 und 35 geleitet wird. Die Funktionsweise und die Kolben, usw. sind identisch wie beim ersten Ausführungsbeispiel.The compressed air supply is the same as in the first exemplary embodiment, the handle 31 being attached to the middle cylinder 2 and a triple distributor 38 being provided instead of a double distributor 25, so that the compressed air is supplied both to the glue cylinder 2 and via lines 26 and 57 to the other two Glue cylinder 3 and 35 is passed. The mode of operation and the pistons, etc. are identical to those in the first exemplary embodiment.
In dem Ausführungsbeispiel gemäss den Figuren 7 und 8 ist eine Ausführungsvariante dargestellt, in welcher keine Druckluft zum Austragen des Leims benötigt wird, sondern ein mechanischer Antrieb des Austragkolbens erfolgt. Dies hat den Vorteil, dass keine Druckluftleitung benötigt wird, die nicht überall vorhanden ist, und dass auf keinen oftmals störenden Zuleitungsschlauch Rücksicht genommen werden uss.In the exemplary embodiment according to FIGS. 7 and 8, an embodiment variant is shown in which no compressed air is required to discharge the glue, but instead a mechanical drive of the discharge piston takes place. This has the advantage that no compressed air line is required, which is not available everywhere, and that no often disruptive supply hose is taken into account.
Die Vorrichtung 42 weist analog zur Vorrichtung 1 zwei Leimzylinder 43 und 44 auf, die über die selben Brillen 17 und 18 miteinander verbunden sind. Der Zylinderauslass 12 sowie die Düsen und vor allem die Leimleiste sind die gleichen wie beim ersten Ausführungsbeispiel.The device 42 has, analogously to the device 1, two glue cylinders 43 and 44 which over the same glasses 17 and 18 are interconnected. The cylinder outlet 12 and the nozzles and especially the glue strip are the same as in the first embodiment.
Der Leim wird mittels einer Gewindestange 45 ausgetragen, die zwischen den beiden Leimzylindern angeordnet ist und die durch Lager 46 und 47 geführt ist. Die Gewindestange kann beispielsweise an ihrem einen Ende einen Innensechskant 48 aufweisen, um von einem Gerät, wie es sich auf dem Bau befindet, beispielsweise einem Akkubohrer, angetrieben zu werden. Die Lagerungen 46, 47 sind an sich bekannte Kugellager Lagerungen und werden hier nicht im Detail erläutert.The glue is discharged by means of a threaded rod 45 which is arranged between the two glue cylinders and which is guided through bearings 46 and 47. The threaded rod can, for example, have an internal hexagon 48 at one end in order to be driven by a device such as is currently under construction, for example a cordless drill. The bearings 46, 47 are known ball bearing bearings and are not explained in detail here.
Die Gewindestange 45 ist über ein Mutterstück 49 und eine durchgehende Kolbenverbindung 50 mit den beiden Kolben 52 verbunden. Die Kolbenverbindung ist mit dem Kolben über ein Verbindungsstück 51 verbunden, das am zweiteiligen Kolben 52 befestigt ist. Der Kolben 52 besteht aus einem Frontteil 53 und einer beabstandeten Führung 54, wobei dasThe threaded rod 45 is connected to the two pistons 52 via a nut piece 49 and a continuous piston connection 50. The piston connection is connected to the piston via a connecting piece 51 which is attached to the two-part piston 52. The piston 52 consists of a front part 53 and a spaced guide 54, the
Verbindungsstück 51 an beiden Teilen befestigt ist.Connector 51 is attached to both parts.
Das Frontteil des Kolbens ist gleich gestaltet wie bei den vorhergehenden Ausführungsbeispielen, um den Leim so vollständig wie möglich auszutragen. Der Leimzylinder ist oben mit einem Schraubdeckel 55 abgeschlossen. Um die Bewegung der Kolbenverbindung zu ermöglichen, ist das Leimzylinderrohr 56 geschlitzt, wie dies aus Fig. 7 hervorgeht. Zum Füllen des Leimzylinders wird das Mutterstück mit dem Kolben in Richtung Schraubdeckel gezogen, woraufhin die Leimbeutel eingefüllt werden können und die Leimleiste mittels der Muttern 12M befestigt werden kann. Ausgehend von diesem Beispiel mit zwei Leimzylindern ist es auch möglich, Vorrichtungen mit mehr als zwei Leimzylindern mit mechanischem Kolbenantrieb vorzusehen, wobei der mechanische Vortrieb angepasst werden muss. Der Antrieb der Gewindestange oder einer ähnlichen Einrichtung kann auch über andere Antriebe als Akkubohrer oder dergleichen erfolgen, beispielsweise über einen Elektromotor oder dergleichen, auch hier vorzugsweise mit Batterien oder wiederaufladbaren Batterien betrieben.The front part of the piston is designed in the same way as in the previous exemplary embodiments in order to discharge the glue as completely as possible. The glue cylinder is closed at the top with a screw cap 55. In order to enable the movement of the piston connection, the glue cylinder tube 56 is slotted, as can be seen from FIG. 7. To fill the glue cylinder, the nut piece with the piston is pulled in the direction of the screw cap, whereupon the glue bags can be filled in and the glue strip can be fastened using the nuts 12M. Starting from this example with two glue cylinders, it is also possible to provide devices with more than two glue cylinders with a mechanical piston drive, the mechanical propulsion having to be adapted. The threaded rod or a similar device can also be driven via drives other than cordless drills or the like, for example via an electric motor or the like, preferably also operated here with batteries or rechargeable batteries.
Von den oben beschriebenen Ausführungsbeispielen gemäss den Figuren 1 - 8 ausgehend ist es ersichtlich, dass sowohl Vorrichtungen mit einem Leimzylinder und einer entsprechend angepassten Leimleiste als auch Vorrichtungen mit mehr als drei Leimzylindern möglich ist, wobei jeweils die Leimleiste analog ausgeführt ist und aus zwei Teilen besteht sowie beidseitig zwei Gleitrollen aufweist. Allen Leimleisten gemeinsam ist, dass sie mit einem leimabweisenden Kunststoff überzogen sind, um eine sehr schnelle Reinigung durchführen zu können. Bei den Leimbehältern muss es sich nicht notwendigerweise um Leimzylinder handeln, andere Formen sind ebenso möglich.Based on the exemplary embodiments described above in accordance with FIGS. 1-8, it can be seen that both devices with a glue cylinder and a correspondingly adapted glue bar and devices with more than three glue cylinders are possible, the glue bar being designed analogously and consisting of two parts and has two castors on both sides. All glue strips have in common that they are covered with a glue-repellent plastic so that they can be cleaned very quickly. The glue containers do not necessarily have to be glue cylinders, other shapes are also possible.
In den Figuren 9 und 10 ist ein weiteres Ausführungsbeispiel dargestellt, das eine wesentliche Vereinfachung bringt. Die Leimleiste 57 ist an eine Vorrichtung 58 angeschlossen, die drei Leimzylinder 59, 60 und 61 aufweist, ähnlich wie in der Vorrichtung 34, wobei die gleichen Teile mit den gleichen Hinweisziffern versehen sind und die übrigen Teile der Vorrichtung dieselben wie die vorhergehend beschriebenen sind.A further exemplary embodiment is shown in FIGS. 9 and 10, which brings a substantial simplification. The glue strip 57 is connected to a device 58 which has three glue cylinders 59, 60 and 61, similar to the device 34, the same parts being provided with the same reference numerals and the remaining parts of the device being the same as those described above.
In Abweichung zu den vorhergehenden Beispielen ist die Leimleiste 57 einstückig aus einem leimabweisenden Kunststoff hergestellt und weist einen durchgehenden Längskanal 62 auf, in den die Auslässe 63 - 65 eines Übergangsstückes 66 münden, wobei der Längskanal 62 als Hohlraum dient, von welchem Auslass-Kanäle 67 ausgehen, die in die Austragöffnungen 68 münden.In deviation from the previous examples, the glue strip 57 is made in one piece from a glue-repellent plastic and has a continuous one Longitudinal channel 62, into which the outlets 63-65 of a transition piece 66 open, the longitudinal channel 62 serving as a cavity, from which outlet channels 67 extend, which open into the discharge openings 68.
Wie aus Figur 10 hervorgeht, ist das Gehäuse 69 der Leimleiste nicht symmetrisch bezüglich der Austragöffnungen 68 ausgebildet, indem diese oberhalb des Scheitels des sich verjüngenden Gehäuses angeordnet sind. In Figur 10 bedeutet "oberhalb" die Lage in Bezug auf das Gerat beim Benutzen auf einem Boden. Dadurch wird ein besserer und gleichmässigerer Leimfluss gewährleistet.As can be seen from FIG. 10, the housing 69 of the glue strip is not formed symmetrically with respect to the discharge openings 68 in that these are arranged above the apex of the tapered housing. In Figure 10, "above" means the location with respect to the device when used on a floor. This ensures a better and more even glue flow.
Die asymmetrische Lage der Austragöffnungen ist auch für die vorhergehend beschriebenen Leimleisten 4 und 36 von Vorteil.The asymmetrical position of the discharge openings is also advantageous for the previously described glue strips 4 and 36.
Die Leimleiste 57 weist ähnliche Rollen 15 auf wie vorhergehend, die an einem Vierkantrohr 70 befestigt sind, das oberhalb der Leimleisten-Einlässe verläuft. Dies erlaubt die Befestigung der drei Übergangsstücke 66 mit den trichterförmigen Düsen 9 und den Auslässen 63 - 65 sowie den Muttern 12M, die der Aufnahme und Befestigung der Leimzylinder 59 - 61 mit den Leimbeuteln dienen, daran, wodurch eine weitere Vereinfachung erzielt wird. Das Vierkantrohr 70 ist mittels zwei beidseitig verlaufenden, seitlichen Blechleisten 71 am Gehäuse 69 befestigt. Die Rollen 15 sind ebenfalls an den Seitenblechen 71, innen, befestigt . The glue bar 57 has similar rollers 15 as before, which are fastened to a square tube 70 which runs above the glue bar inlets. This allows the three transition pieces 66 with the funnel-shaped nozzles 9 and the outlets 63-65 and the nuts 12M, which serve to receive and fasten the glue cylinders 59-61 with the glue bags, to be fastened to them, thereby achieving a further simplification. The square tube 70 is fastened to the housing 69 by means of two sheet metal strips 71 running on both sides. The rollers 15 are also attached to the side plates 71, inside.
