Description

Die vorliegende Erfindung betrifft eine Absauganlage für pulverförmiges Gut, insbesondere für Pulverbeschichtungskabinen mit mindestens einer bewegten Saugdüse, mindestens einem mit der Saugdüse in Wirkverbindung stehendem Saugluftkanal mit einem Saugzuggebläse, sowie eine Pulverbeschichtungskabine mit Bodenfilter und bewglicher Absaugdüse, Bodenwanne und Absaugventilator, die gemäss der europäischen Patentanmeldung Nr. O 141 778 dazu geeignet ist, versprühtes Pulver auf kürzestem Wege wieder in den Abgabebehälter zurückzutransportieren.The present invention relates to a suction system for powdery material, in particular for powder coating booths with at least one moving suction nozzle, at least one suction air duct with a suction blower that is operatively connected to the suction nozzle, and a powder coating booth with floor filter and movable suction nozzle, floor pan and suction fan, which according to the European patent application No. O 141 778 is suitable for transporting sprayed powder back into the dispensing container in the shortest possible way.

Bei der in dieser Anmeldung beschriebenen Kabine treten gewisse Probleme bezüglich des Ueberganges von der sich in Längsrichtung bewegenden Düse zum Absaugsystem auf.The cabin described in this application has certain problems with the transition from the longitudinally moving nozzle to the suction system.

Bei der Kabine gemäss dieser Patentanmeldung ist das Filterband während des Beschichtens stationär. Eine Düse wandert über die gesamte Länge des Bandes hin und her, wobei durch Schlitze das herabgefallene Pulver eingesammelt wird. Eine Verbindung mittels Schlauch von dieser Düse zur Aussenseite hat den Nachteil, dass sich der Schlauch immer im Bereich der Beschichtung befindet, was zu Störungen führen kann.In the cabin according to this patent application, the filter belt is stationary during the coating. A nozzle travels back and forth along the entire length of the belt, with the powder that has fallen down being collected through slots. A connection by means of a hose from this nozzle to the outside has the disadvantage that the hose is always in the area of the coating, which can lead to faults.

Diesen Nachteil behebt die vorliegende Erfindung, welche sich durch einen der Ansprüche auszeichnet.The present invention, which is characterized by one of the claims, overcomes this disadvantage.

Die Erfindung bietet eine optimale Lösung für den Luftweg der Absaugung und die Reinigung sowie weitere vorteilhafte technische Lösungen, die den Farbwechsel vereinfachen.The invention offers an optimal solution for the airway of the suction and cleaning as well as further advantageous technical solutions that simplify the color change.

Die Erfindung wird anschliessend beispielsweise anhand einer Zeichnung erläutert.The invention is subsequently explained, for example, using a drawing.

Die in Fig. 1 dargestellte, bekannte elektrostatische Pulverbeschichtungsanlage 1 ist mit einer Kabine 2 versehen, in der eine Einrichtung 3 zur Abgabe von elektrostatisch aufgeladenem Pulver angeordnet ist. Im Innenraum der Kabine 2 ist bodenseitig 10 ein durch die Kabine 2 bewegbares Filterband 5 vorgesehen. Ein erstes Sauggebläse 35 ist grossflächig im Bereich des Bodens 10 der Kabine 2 angeschlossen. Es erzeugt durch das Filterband 5 hindurch in der Kabine 2 ein Saugfeld mit Unterdruck. Eine dem Filterband 5 zugeordnete Reinigungseinrichtung 13 dient der Entfernung des auf dem Filterband 5 liegenden überschüssigen Pulvers. Betätigungsmittel 6, 7 ermöglichen bei Farbwechsel, das Filterband 5 um mindestens eine Kabinenlänge nachzuziehen und damit jeder Farbe ihre Filterbandzone zuzuteilen. Diese Mehrfarbenkabine stellt aufwands-und zeitmässig ein Optimum dar. Die Pulverrückgewinnungsanlage ist der Vollständigkeit halber auch dargestellt, obschon sie die vorliegende Erfindung nicht berührt.The known electrostatic powder coating system 1 shown in FIG. 1 is provided with a cabin 2 in which a device 3 for dispensing electrostatically charged powder is arranged. In the interior of the cabin 2, a filter belt 5 movable through the cabin 2 is provided on the bottom side 10. A first suction fan 35 is connected over a large area in the area of the floor 10 of the cabin 2. It creates a suction field with negative pressure through the filter belt 5 in the cabin 2. A cleaning device 13 assigned to the filter belt 5 serves to remove the excess powder lying on the filter belt 5. When changing colors, actuating means 6, 7 enable the filter band 5 to be retightened by at least one cabin length and thus to assign each filter color to its filter band zone. This multicolor booth represents an optimum in terms of expenditure and time. The powder recovery system is also shown for the sake of completeness, although it does not affect the present invention.

Fig. 2 stellt die Seitenansicht der Kabine 2 dar. Deren Beschichtungsraum 51 wird von Blechwänden umgeben. Ein bandförmiges Bodenfilter 52 wird an beiden Enden auf Walzen 53 fixiert. Die Abluft wird über eine Bodenwanne 58 und einen Abluftkanal 59 über einen Ventilator, entsprechend dem Ventilator 35 in Fig. 1, ins Freie geführt.Fig. 2 shows the side view of the cabin 2. Its coating space 51 is surrounded by sheet metal walls. A band-shaped bottom filter 52 is fixed on rollers 53 at both ends. The exhaust air is led into the open via a floor pan 58 and an exhaust air duct 59 via a fan, corresponding to the fan 35 in FIG. 1.

Für die Bandreinigung ist eine Absaugdüse 56 vorgesehen, die über einen Antrieb mit einem bzw. zwei Antriebsriemen 54 und einem Motor 55 über das Bodenfilter 52 hin- und herbewegt wird. Die beiden gegenüberliegenden Riemen 54, als Zahnriemen ausgebildet, sind durch eine Verbindungswelle gekoppelt (nicht dargestellt), um einen synchronen Lauf zu erhalten.For the belt cleaning, a suction nozzle 56 is provided, which is driven by a drive with one or two drive belts 54 and a motor 55 via the bottom filter 52 is moved back and forth. The two opposing belts 54, designed as toothed belts, are coupled by a connecting shaft (not shown) in order to obtain synchronous running.

In Fig. 4 ist die Konstruktion des Bodenfilters 52 sowie der Bodenwanne 58 gezeigt. Wichtig für eine solche Anlage ist es, dass die Luftverteilung am Bodenfilter 52 für die Absaugung gleichmässig ist, um Ueberlastungen der einzelnen Filterbandsegmente zu verhindern. Beim Reinigen und Farbwechsel muss aber der Kabinenboden unbedingt begehbar sein. All diese Anforderungen können am besten dadurch erreicht werden, dass die Bodenwanne 58 mit einem Lochblech 61 von ca. 5 - 20 mm Durchmesser bedeckt wird. Darüber wird ein Kunststoffband 60 mit,z.B. runden oder rechteckigen, Oeffnungen von 3 - 10 mm Durchmesser bzw. Seitenlänge gelegt, damit die Luftführung weiter verbessert wird und bei Farbwechsel durch Drehen der Walzen 53 keine Beschädigung auftritt. Beim Farbwechsel ist es auch wichtig, dass der Arbeiter nicht durch die wandernde Düse verletzt wird. Dies geschieht durch den Einbau einer Rutschkupplung 62 im Zahnriemenantrieb.4 shows the construction of the bottom filter 52 and the bottom pan 58. It is important for such a system that the air distribution at the bottom filter 52 for the suction is uniform in order to prevent overloading of the individual filter belt segments. When cleaning and changing the color, the cabin floor must be accessible. All of these requirements can best be achieved by covering the floor pan 58 with a perforated plate 61 of approximately 5-20 mm in diameter. A plastic band 60 with, e.g. round or rectangular, openings of 3 - 10 mm in diameter or side length, so that the air flow is further improved and no damage occurs when changing color by rotating the rollers 53. When changing colors, it is also important that the worker is not injured by the moving nozzle. This is done by installing a slip clutch 62 in the toothed belt drive.

Für die Funktion dieses Systems ist von entscheidender Bedeutung,dass die Absaugung des Pulvers gut erfolgt, da sonst die Reinigung nicht gewährleistet ist. Die Düse 56 wird in einen sogenannten Führungsrahmen 63 eingelegt (Fig. 4, 5). Dieser Führungsrahmen 63 ist auf beiden Seiten mit dem Antrieb der Zahnriemen 54 fest verbunden. Der Riemen 54 ist hier unterbrochen und diese freien Enden werden über den Führungsrahmen 63 verbunden (Fig. 6).For the function of this system, it is crucial that the powder is extracted well, otherwise cleaning is not guaranteed. The nozzle 56 is placed in a so-called guide frame 63 (FIGS. 4, 5). This guide frame 63 is firmly connected on both sides to the drive of the toothed belt 54. The belt 54 is interrupted here and these free ends are connected via the guide frame 63 (Fig. 6).

Der Führungsrahmen 63 ist so ausgebildet, dass an den Enden ein Uebergang der Luft auf einen Längskanal 57 über ein Führungsrahmenendprofil 65 möglich ist. Dieses Profil 65 reicht bis zum Filterbandanfang. Danach besteht der Führungsrahmen 63 aus zwei parallelen Stegen, in welche die Düse 56 bildende Düsenelemente 73 eingelegt sind.The guide frame 63 is designed in such a way that a transition of the air to a longitudinal channel 57 via a guide frame end profile 65 is possible at the ends. This profile 65 extends to the beginning of the filter belt. Thereafter, the guide frame 63 consists of two parallel webs, into which nozzle elements 73 forming the nozzle 56 are inserted.

Die Absaugdüse 56 ist so aufgebaut, dass sie, abhängig von der Bandbreite, aus einem oder mehreren dieser Elemente 73 besteht. Der Grund dieser Massnahme liegt darin, dass sich die einzelnen Elemente 73 optimal allfälligen Unebenheiten und Ungenauigkeiten des Bodenfilters 52, z.B. der Auflage, anpassen können.The suction nozzle 56 is constructed such that, depending on the bandwidth, it consists of one or more of these elements 73. The reason for this measure is that the individual elements 73 optimally compensate for any unevenness and inaccuracies in the floor filter 52, e.g. of the edition, can adjust.

An einem Ende sind oben und seitlich die Elemente 73 mit Gummilippen 67 versehen, um eine bessere Abdichtung zu erhalten. Die Düsenelemente 73 sind aus, z.B. runden oder viereckigen, Profilen gemacht. An der Unterseite sind Teflonauflagen 68 angebracht, damit der Bandabrieb und die Reibung möglichst gering bleiben. Dem Absaugen dienende Längsschlitze 64 sind entweder durchgehend mit ca. 2 - 10 mm Breite vorgesehen, oder in zwei Reihen, gegenseitig versetzt, was eine verbesserte Reinigung ergibt.At one end, the elements 73 are provided with rubber lips 67 at the top and sides in order to obtain a better seal. The nozzle elements 73 are made of e.g. round or square, made of profiles. Teflon pads 68 are attached to the underside so that the band abrasion and the friction remain as low as possible. Longitudinal slots 64 for suction are either provided continuously with a width of approximately 2 to 10 mm, or in two rows, mutually offset, which results in improved cleaning.

Von der hin- und herbewegten Absaugdüse 56 wird im Betrieb das Pulver-Luftgemisch über die Führungsrahmen-Endprofile 65 in den Längskanal 57 geführt. Dieser besteht aus, z.B. runden oder viereckigen, Profilen mit einem Längsschlitz 64 an der Oberseite. Darin läuft eine Führung 69 für den Führungsrahmen 63. Abgedeckt wird im übrigen der Längsschlitz 64 durch den Antriebsriemen 54, der durch den im Längskanal 66 herrschenden Unterdruck angesaugt wird und somit dichtet. Über einen Absaugstutzen 71 wird dann das Luft-Pulvergemisch in eine Rückgewinnungsanlage (Fig. 1) gebracht. Vorzugsweise werden am Längskanal 57 mehrere Absaugstutzen 71 angebracht, da dadurch die Lage des Absaugsystems optimal gewählt werden kann. Beim Reinigen kann an einem der Stützen 71 eine Saugdüse für die Wände etc. angeschlossen werden.During operation, the powder-air mixture is guided from the reciprocating suction nozzle 56 via the guide frame end profiles 65 into the longitudinal channel 57. This consists of, for example, round or square profiles with a longitudinal slot 64 on the top. In this runs a guide 69 for the guide frame 63. The longitudinal slot 64 is also covered by the drive belt 54, which is sucked in by the negative pressure prevailing in the longitudinal channel 66 and thus seals. The air-powder mixture is then brought into a recovery system (FIG. 1) via a suction nozzle 71. A plurality of suction nozzles 71 are preferably attached to the longitudinal channel 57, since this allows the position of the suction system to be optimally selected. When cleaning, a suction nozzle for the walls etc. can be connected to one of the supports 71.

Bei Mehrfarbenanlagen kann an beiden Seiten der Kabine ein Längskanal 66 angebracht werden (Fig. 3). Hier ist es beim Farbwechsel dann nötig, die Düsenelemente zu reinigen und vom einen Längskanal 66 auf den anderen umzustellen.In multi-color systems, a longitudinal channel 66 can be attached to both sides of the cabin (FIG. 3). When changing colors, it is then necessary to clean the nozzle elements and to switch from one longitudinal channel 66 to the other.

Die Absaugeinheit kann dann am zweiten Längskanal 66 angeschlossen werden oder sogar als zweite Einheit für die nächste Farbe zur Verfügung stehen. Dies spart beim Farbwechsel weiter Zeit, da der Reinigungsaufwand verringert wird.The suction unit can then be connected to the second longitudinal channel 66 or even be available as a second unit for the next color. This saves time when changing colors because the cleaning effort is reduced.

Die Längskanäle 57 sind an den Enden mit Deckeln 72 versehen, so dass der Kanal mittels Bürste bei Bedarf rasch gereinigt werden kann. Solche Deckel 72 sind auch an den Profilen 65 des Führungsrahmens 63 angebracht.The longitudinal channels 57 are provided with lids 72 at the ends, so that the channel can be quickly cleaned by means of a brush if necessary. Such covers 72 are also attached to the profiles 65 of the guide frame 63.
