Description

Die Erfindung betrifft eine Einrichtung zum Trocknen eines Maschinenteiles mit einer Vakuumtrockenkammer, an welche zumindest eine Evakuiereinrichtung angeschlossen ist.The invention relates to a device for drying a machine part with a vacuum drying chamber to which at least one Evakuiereinrichtung is connected.

Aus der GB 2 268 253 A1 ist eine Einrichtung zum Trocknen von Kugellagern bekannt, welche ein zweiteiliges Gehäuse aufweist, wobei die beiden Gehäusehälften über eine Dichtung abgedichtet sind.From the GB 2 268 253 A1 a device for drying ball bearings is known, which has a two-part housing, wherein the two housing halves are sealed by a seal.

Mehrteilige Vakuumtrockenkammern haben den Nachteil, dass insbesondere bei großvolumigen Vakuumtrockenkammern ein relativ hoher Aufwand zur Verhinderung von Leckagen erforderlich ist.Multi-part vacuum drying chambers have the disadvantage that, in particular for large-volume vacuum drying chambers, a relatively high outlay for preventing leaks is required.

Die JP 2003-080182 A offenbart eine Wasch- und Trocknungseinrichtung für Teile, wobei die Innenfläche eines klappbaren Deckels abfallend geneigt ist, um ein Abtropfen auf die Teile zu vermeiden.The JP 2003-080182 A discloses a parts washing and drying device wherein the inner surface of a hinged lid slopes downwardly to prevent dripping onto the parts.

Die JP 2003-080187 A beschreibt eine ähnliche Einrichtung, bei der der Druck während des Wasch- und Trocknungsvorganges reduziert wird.The JP 2003-080187 A describes a similar device in which the pressure during the washing and drying process is reduced.

Aus der DE 42 37 335 A1 ist eine Verfahren und eine Einrichtung zur Trocknung eines mit einer Reinigungsflüssigkeit behandelten Werkstückes bekannt, wobei das Werkstück in einer luftdicht verschließbaren Kammer einem Unterdruck ausgesetzt wird. Dabei wird die Kammer zum Verdampfen von Reinigungsflüssigkeit an der Werkstückoberfläche evakuiert und die Oberflächenbereiche danach durch entsprechende Blasdüsen erzeugten Luftstrahlen ausgesetzt, um Reinigungsflüssigkeit zu verteilen bzw. zu entfernen. Die Schritte des Evakuierens und des Beauschlagen mit Luftstrahlen werden dabei abwechselnd durchgeführt. Der Innenraum der Kammer ist dabei nur so groß, dass er zur Aufnahme des Werkstückes ausreicht.From the DE 42 37 335 A1 a method and a device for drying a treated with a cleaning liquid workpiece is known, wherein the workpiece is subjected to a vacuum in an airtight sealable chamber. In this case, the chamber is evacuated for evaporating cleaning liquid on the workpiece surface, and the surface areas are then exposed to air jets generated by corresponding blowing nozzles in order to distribute or remove cleaning liquid. The steps of evacuation and Beauschlagen with air jets are performed alternately. The interior of the chamber is only so large that it is sufficient to accommodate the workpiece.

Weiters ist ein Verfahren zur Reinigung eines Gegenstandes aus der WO 2006/129402 A1 bekannt. Dabei wird der zu reinigende Gegenstand in einen rohrförmigen Behälter eingebracht, dessen Stirnseiten durch Deckel druckdicht verschlossen werden. Der Behälter ist mit Dampferzeugungsmittel oder mit druckreduzierenden Einrichtungen verbindbar.Furthermore, a method for cleaning an article from the WO 2006/129402 A1 known. In this case, the object to be cleaned is introduced into a tubular container whose end faces are sealed pressure-tight by the lid. The container is connectable to steam generating means or to pressure reducing means.

Die EP 1 057 400 A2 beschreibt eine Einrichtung zum Trocknen von Futtermittel mit einem hermetisch verschließbaren Behälter, welcher durch eine Vakuumpumpe evakuierbar ist. Weitere Evakuierbare Behälter sind aus der US 6,598,517 B1 , oder der DE 299 027 B bekannt.The EP 1 057 400 A2 describes a device for drying feed with a hermetically sealable container which can be evacuated by a vacuum pump. Further evacuable containers are out of the US Pat. No. 6,598,517 B1 , or the DE 299 027 B known.

Aufgabe der Erfindung ist es, die genannten Nachteil zu vermeiden und auf möglichst einfache Weise eine schnelle Endtrocknung von Maschinenteilen zu ermöglichen.The object of the invention is to avoid the above drawback and to allow the simplest possible way a quick final drying of machine parts.

Erfindungsgemäß wird dies dadurch erreicht, dass die Wände der Vakuumtrockenkammer einstückig ausgebildet sind, wobei vorzugsweise die Vakuumtrockenkammer aus einem einzigen Teil - also ohne nachträgliches Zusammenfügen von mehreren Teilen durch Schweißen, Kleben , Löten oder dergleichen - gefertigt ist.According to the invention this is achieved in that the walls of the vacuum drying chamber are integrally formed, wherein preferably the vacuum drying chamber of a single part - ie without subsequent joining of several parts by welding, gluing, soldering or the like - is made.

Zwar ist eine Fertigung aus mehreren Teilen und untrennbares Zusammenfügen durch Schweißen oder dergleichen möglich und denkbar, allerdings ist eine druckdichte Herstellung der Vakuumkammer relativ aufwändig in der Fertigung, insbesondere wenn die Wände der Vakuumtrockenkammer aus Aluminium oder einer Aluminiumlegierung bestehen.Although a production of several parts and inseparable joining by welding or the like is possible and conceivable, but a pressure-tight production of the vacuum chamber is relatively expensive to manufacture, especially if the walls of the vacuum drying chamber made of aluminum or an aluminum alloy.

Um mit möglichst geringem Fertigungsaufwand eine druckdichte Vakuumkammer zu realisieren, ist es besonders vorteilhaft, wenn die Vakuumtrockenkammer aus dem Vollen gefräst ist. Das Fräsen aus dem Vollen hat den Vorteil, dass unterschiedlichste Formen und Dimensionen von Vakuumkammern relativ rasch und mit geringem Aufwand herstellbar sind.In order to realize a pressure-tight vacuum chamber with the least possible manufacturing effort, it is particularly advantageous if the vacuum drying chamber is milled from the solid. The milling from the solid has the advantage that a wide variety of shapes and dimensions of vacuum chambers can be produced relatively quickly and with little effort.

Die Vakuumtrockenkammer kann dabei als Sackkammer mit einer einzigen durch eine Türe gasdicht verschließbaren Ein- und Austrittsöffnung oder als Durchgangskammer mit zwei durch jeweils eine Türe gasdicht verschließbaren Ein- und Austrittsöffnungen ausgebildet sein.The vacuum drying chamber can be designed as a bag chamber with a single gas-tight by a door closable inlet and outlet openings or as a passage chamber with two gas-tight by a door closable inlet and outlet openings.

Zur Beschleunigung des Trocknungsvorganges ist es vorteilhaft, wenn das Gehäuse zumindest einen Anschluss für eine Spülluftleitung aufweist. Über die Spülluftleitungen kann der Vakuumtrockenvorgang durch eine Spülphase unterbrochen werden.To accelerate the drying process, it is advantageous if the housing has at least one connection for a scavenging air line. About the scavenging air, the vacuum drying process can be interrupted by a rinsing phase.

Beim Trockenvorgang kann es an den Wänden und an der Decke zu Wandniederschlag kommen. Um Tropfenbildung zu vermeiden bzw. Kondenswasser abführen zu können, ist es vorteilhaft, wenn - in der Betriebslage betrachtet - alle Innenflächen, vorzugsweise auch die Decke, der Vakuumtrockenkammer abfallend ausgebildet, vorzugsweise bezüglich einer waagrechten Ebene geneigt ausgeführt sind.During the drying process, wall precipitation may occur on the walls and on the ceiling. In order to avoid droplets or to be able to remove condensation, it is advantageous if - viewed in the operating position - all inner surfaces, preferably also the ceiling, the vacuum drying chamber formed sloping, preferably inclined with respect to a horizontal plane.

Um abtropfende Flüssigkeit zu sammeln ist es vorteilhaft, wenn das Gehäuse einen abfallenden Boden aufweist. Die sich ansammelnde Flüssigkeit wird am Ende des Evakuiervorganges über ein Abflussventil aus der Vakuumtrockenkammer abgelassen.To collect dripping liquid, it is advantageous if the housing has a sloping bottom. The accumulating liquid is discharged at the end of the evacuation process via a drain valve from the vacuum drying chamber.

Um den Evakuiervorgang möglichst rasch durchführen zu können ist es vorteilhaft, wenn dass die Wände der Vakuumtrockenkammer zumindest teilweise dem zu trocknenden Maschinenteil nachgeformt sind, wobei vorzugsweise die Seitenwände und/oder die Decke der Vakuumtrockenkammer parallel zu einem Profil des Maschinenteils gestaltet sind. Vorzugsweise kann dabei vorgesehen sein, dass die Seitenwände und/oder die Decke der Vakuumtrockenkammer so gestaltet sind, dass - bei in die Vakuumtrockenkammer eingefahrenem oder eingelegtem Maschinenteil- der Normalabstand zwischen jeder Innenfläche der Seitenwände und/oder Decke und dem Maschinenteil an jeder Stelle weniger als 100 mm, vorzugsweise weniger als 50 mm, besonders vorzugsweise weniger als 5 mm beträgt.In order to carry out the evacuation process as quickly as possible, it is advantageous if the walls of the vacuum drying chamber are at least partially reshaped to the machine part to be dried, wherein preferably the side walls and / or the ceiling of the vacuum drying chamber are designed parallel to a profile of the machine part. Preferably, it may be provided that the side walls and / or the ceiling of the vacuum drying chamber are designed so that - when in the vacuum drying chamber retracted or inlaid Maschinenteil- the normal distance between each inner surface of the side walls and / or ceiling and the machine part at each point less than 100 mm, preferably less than 50 mm, particularly preferably less than 5 mm.

Mit heute üblichen CNC- Frästechniken ist durch Fertigung aus dem vollen Block eine exakte Nachformung an den Maschinenteil mit geringem Aufwand möglich.With today's customary CNC milling techniques, an exact reshaping of the machine part with little effort is possible by production from the full block.

Für unterschiedlich geformte oder dimensionierte Maschinenteile sind somit verschiedene Vakuumkammern erforderlich. Eine einfacher Wechsel der Vakuumkammer kann realisiert werden, wenn die Vakuumtrockenkammer als austauschbares Kammermodul ausgebildet ist, welches in eine feststehende Basiseinheit einsetzbar ist, wobei die Basiseinheit zumindest eine Türe, vorzugsweise zwei voneinander beabstandete Türen, samt Türrahmen und Aktuatoren, zumindest einem Anschluss für eine Spülleitung, und/oder eine Vakuumleitung aufweist. Um die Umrüstung weiter zu vereinfachen und die Stillstandszeiten möglichst klein zu halten ist es besonders vorteilhaft, wenn die zumindest eine Türe bzw. Eintritts- und/oder Austrittsöffnung, und der zumindest eine Anschluss für eine Spülleitung, und/oder eine Vakuumleitung bei der Basiseinheit und/oder dem Kammermodul standardisiert ist. Somit sind die Anschlüsse für eine Spülleitung und/oder eine Vakuumleitung bei verschiedenen Kammermodulen an genau definierten Bereichen an der äußeren Oberfläche angeordnet, so dass ein einfaches Anschließen beim Aufsetzen des Kammermoduls auf der Basiseinheit erfolgen kann. Gleiches gilt für die Eintritt- und Austrittsöffnungen. Optisch weisen somit unterschiedliche Kammermodule das gleiche würfel- oder quaderförmige Erscheinungsbild auf, während sie sich durch die Form und/oder Größe der Vakuumkammer im Inneren wesentlich von einander unterscheiden.For different shaped or dimensioned machine parts thus different vacuum chambers are required. A simple change of the vacuum chamber can be realized if the vacuum drying chamber is designed as a replaceable chamber module, which is insertable into a fixed base unit, wherein the base unit at least one door, preferably two spaced apart doors, including door frame and actuators, at least one connection for a purge line , and / or having a vacuum line. To further simplify the conversion and keep the downtime as small as possible, it is particularly advantageous if the at least one door or inlet and / or outlet opening, and the at least one connection for a purge line, and / or a vacuum line in the base unit and / or the chamber module is standardized. Thus, the connections for a purge line and / or a vacuum line are arranged at different chamber modules at precisely defined areas on the outer surface, so that a simple connection can be made when placing the chamber module on the base unit. The same applies to the inlet and outlet openings. Optically, therefore, different chamber modules have the same cubic or cuboidal appearance, while they differ significantly from each other by the shape and / or size of the vacuum chamber in the interior.

Das erfindungsgemäße Trocknungsverfahren beinhaltet folgende Schritte:

  1. a) Einbringen des Maschinenteils in die entsprechend dem Profil des Maschinenteils geformte Vakuumtrockenkammer, vorzugsweise über eine Rollenbahn;
  2. b) gasdichtes Verschließen der Vakuumtrockenkammer, vorzugsweise über zumindest einen Schieber;
  3. c) Durchführen eines Evakuiervorganges durch Absenken des Druckes in der Vakuumtrockenkammer auf einen definierten Druck;
  4. d) Erhöhen des Druckes in der Vakuumtrockenkammer und Durchführen zumindest eines Zwischenspülvorganges mit einem vorzugsweise gasförmigen Spülmedium;
  5. e) Durchführen eines nochmaligen Evakuiervorganges durch Absenken des Druckes in der Vakuumtrockenkammer auf einen definierten Druck;
  6. f) Entfernen des Maschinenteiles nach Erhöhen des Druckes und Öffnen der Vakuumtrockenkammer.
The drying method according to the invention comprises the following steps:
  1. a) introducing the machine part into the vacuum drying chamber formed according to the profile of the machine part, preferably via a roller conveyor;
  2. b) gas-tight closing of the vacuum drying chamber, preferably via at least one slide;
  3. c) performing an evacuation process by lowering the pressure in the vacuum drying chamber to a defined pressure;
  4. d) increasing the pressure in the vacuum drying chamber and performing at least one intermediate rinsing process with a preferably gaseous rinsing medium;
  5. e) carrying out a further evacuation process by lowering the pressure in the vacuum drying chamber to a defined pressure;
  6. f) removing the machine part after increasing the pressure and opening the vacuum drying chamber.

Durch den Zwischenspülvorgang zum Entfernen von Restfeuchtigkeit innerhalb der Vakuumtrockenkammer kann die insgesamt Dauer des Trocknungsvorganges verringert werden. Gegebenenfalls kann der Zwischenspülvorgang wiederholt werden.By the intermediate rinsing process for removing residual moisture within the vacuum drying chamber, the total duration of the drying process can be reduced. If necessary, the intermediate rinsing process can be repeated.

Der Boden 13e der Vakuumtrockenkammer 6 ist abfallend geformt und weist am tiefsten Punkt eine Abflussöffnung 16 mit einem Abflussventil 17 auf.On a side wall 13b of the vacuum drying chamber 6, a connection 14 for an Evakuiereinrichtung 15 is provided, which is arranged below the vacuum drying chamber 6 in the embodiment. The bottom 13e of the vacuum drying chamber 6 is formed sloping and has at the lowest point a drain opening 16 with a drain valve 17.

Weiters weist die Vakuumtrockenkammer 6 einen Anschluss 18 für eine Spülleitung für ein Spülmedium auf.Furthermore, the vacuum drying chamber 6 has a connection 18 for a flushing line for a flushing medium.

Seitlich außen an der Vakuumtrockenkammer 6 ist ein Antriebsmotor 19 für den Rollenbahnabschnitt 5a innerhalb der Vakuumtrockenkammer 6 angeordnet, welche auf Stützelemente 20 vom Boden 13e beabstandet gelagert ist.Laterally outside of the vacuum drying chamber 6, a drive motor 19 is arranged for the roller conveyor section 5a within the vacuum drying chamber 6, which is mounted on support elements 20 spaced from the bottom 13e.

Der eigentlich innerhalb der Vakuumtrockenkammer 6 angeordnete Rollenbahnabschnitt 5a ist samt darauf gelagertem Maschinenteil 2 in Fig. 8 dargestellt, wobei die Wände 13 der Vakuumkammer 6 weggelassen wurden.The actually arranged within the vacuum drying chamber 6 roller conveyor section 5a is together with stored thereon machine part 2 in Fig. 8 shown, wherein the walls 13 of the vacuum chamber 6 have been omitted.

Um ein schnelles Evakuieren zu ermöglichen, sind die Seitenwände 13a, 13b sowie die Decke 13f weitgehend dem zu trocknenden Maschinenteil 2 nachgeformt. Dadurch kann das zu evakuierende Volumen so klein wie möglich gehalten werden. Die Wände 13 im Seiten- und Deckenbereich der Vakuumtrockenkammer 6 sind dabei parallel zum Profil 2a des Maschinenteils 2 - in Förderrichtung betrachtet - ausgebildet und so gestaltet, dass - bei in die Vakuumtrockenkammer 6 eingefahrenem oder eingelegtem Maschinenteil 2 - der Normalabstand a zwischen jeder Innenfläche der Seitenwände 13a, 13b und/oder Decke 13f und dem Maschinenteil 2 an jeder Stelle weniger als 100 mm, vorzugsweise weniger als 50 mm, besonders vorzugsweise weniger als 5 mm beträgt (Fig. 9).In order to enable a rapid evacuation, the side walls 13a, 13b and the ceiling 13f are largely reshaped to the machine part 2 to be dried. As a result, the volume to be evacuated can be kept as small as possible. The walls 13 in the side and ceiling area of the vacuum drying chamber 6 are parallel to the profile 2a of the machine part 2 - viewed in the conveying direction - designed and designed so that - in the vacuum drying chamber 6 retracted or pickled machine part 2 - the normal distance a between each inner surface of Side walls 13a, 13b and / or ceiling 13f and the machine part 2 at each point is less than 100 mm, preferably less than 50 mm, particularly preferably less than 5 mm ( Fig. 9 ).

Um zu vermeiden, dass sich an den Innenflächen der Vakuumkammer 6 bildendes Kondensat auf den Maschinenteil tropfen kann, ist jede Innenfläche abfallend ausgebildet. Insbesondere ist auch die Decke 13f gegenüber einer waagrechten Ebene geneigt ausgebildet, wobei der Neigungswinkel α mindestens 2°, vorzugsweise mindestens 5° betragen kann.In order to avoid that on the inner surfaces of the vacuum chamber 6 forming condensate can drip onto the machine part, each inner surface is formed sloping. In particular, the ceiling 13f is formed inclined with respect to a horizontal plane, wherein the inclination angle α can be at least 2 °, preferably at least 5 °.

Jede Vakuumtrockenkammer 6 ist somit ganz speziell für einen Maschinenteil 2 ausgebildet. Somit müssen für Maschinenteile 2 unterschiedlicher Form und/oder Abmessungen unterschiedlich gestaltete und dimensionierte Vakuumkammern 6 bereitgestellt werden. Um den Umbau der Einrichtung 1 möglichst einfach zu bewerkstelligen und die Stillstandszeit kurz zu halten, ist ein modulartiger Aufbau vorgesehen. Die Vakuumtrockenkammer 6 ist dabei als austauschbares Kammermodul M ausgebildet, welches in eine feststehende Basiseinheit B der Einrichtung 1 eingesetzt werden kann. Die Basiseinheit B weist die beiden voneinander beabstandeten Türen 9, 10 samt Türrahmen 9a, 10a und Aktuatoren 11, 12, sowie zumindest einen Anschluss 18a für eine Spülleitung und/oder eine Vakuumleitung auf. Dabei kann ein einziger Anschluss 18a oder getrennte Anschlüsse zum Spülen und Evakuieren vorgesehen sein. Um den Einsatz von unterschiedlichen Kammermodulen M zu ermöglichen, sind die Türen 9, 10 der Basiseinheit B bzw. die Eintritts- und Austrittsöffnungen 7, 8 verschiedener Kammermodule M standardisiert hinsichtlich Lage, Größe und Anzahl, so dass bei Einsetzen der Kammermodule M in die Basiseinheit B ein Andocken von modulseitigen Anschlüssen und basiseinheitsseitigen Anschlüssen erfolgt. Die druckdichte Verbindung der Anschlüsse kann manuell, oder aber auch automatisch über Schnellkupplungen erreicht werden. Beim Aufsetzen des Kammermoduls M auf der Basiseinheit B kommen die Eintritts- und Austrittsöffnungen 7, 8 lagerichtig im Bereich der Türen 9, 10 zu liegen, wobei eine Abdichtung zwischen Türen 9, 10 und Eintritts-oder Austrittsöffnungen 7, 8 über nicht weiter dargestellte, die Öffnungen umrahmende Dichtelemente erfolgen kann.Each vacuum drying chamber 6 is thus designed especially for a machine part 2. Thus, differently designed and dimensioned vacuum chambers 6 must be provided for machine parts 2 of different shape and / or dimensions. To accomplish the conversion of the device 1 as simple as possible and to keep the downtime short, a modular structure is provided. The vacuum drying chamber 6 is designed as an exchangeable chamber module M, which can be used in a fixed base unit B of the device 1. The base unit B has the two spaced apart doors 9, 10 together with the door frame 9a, 10a and actuators 11, 12, and at least one port 18a for a purge line and / or a vacuum line. In this case, a single connection 18a or separate connections for flushing and evacuation may be provided. In order to enable the use of different chamber modules M, the doors 9, 10 of the base unit B and the inlet and outlet openings 7, 8 of different chamber modules M are standardized in terms of position, size and number, so that when inserting the chamber modules M in the base unit B docking of module-side terminals and base unit-side terminals takes place. The pressure-tight connection of the connections can be achieved manually or automatically via quick couplings. When placing the chamber module M on the base unit B, the inlet and outlet openings 7, 8 come to lie in the correct position in the region of the doors 9, 10, with a seal between doors 9, 10 and entrance or Outlet openings 7, 8 via not shown, the openings framing sealing elements can be done.

Der Maschinenteil 2 gelangt aus der Reinigungsstation 4 kommend über die Rollenbahn 5 der Bearbeitungsstraße 3 in die geöffnete Vakuumtrockenkammer 6. Der Maschinenteil 2 wird dabei lagegenau in die Vakuumtrockenkammer 6 eingebracht, so dass zwischen Maschinenteil 2 und den Wänden 13 im Wesentlichen ein gleichmäßiger Abstand a zwischen 0 mm und 100 mm ausgebildet ist. Danach wird die Vakuumtrockenkammer 6 gasdicht mittels der Türen 9, 10 verschlossen und der Druck von etwa 1 bar Umgebungsdruck auf 0,2 bar abgesenkt. Nach einer vordefinierten Dauer wird die Vakuumtrockenkammer 6 wieder belüftet und über den Anschluss 18 mit einem Spülmedium gespült. Durch die Zwischenspülung wird entstandene Restfeuchtigkeit aus der Vakuumtrockenkammer 6 entfernt. Dann wird die Vakuumtrockenkammer 6 nochmals evakuiert. Das Zwischenspülen kann gegebenenfalls wiederholt werden. Nach dem letzten Evakuiervorgang wird die Vakuumtrockenkammer 6 belüftet und das trockene Maschinenteil 2 durch die geöffnete Austrittsöffnung 8 entfernt.The machine part 2 arrives from the cleaning station 4 coming via the roller conveyor 5 of the processing line 3 in the opened vacuum drying chamber 6. The machine part 2 is precisely placed in the vacuum drying chamber 6, so that between the machine part 2 and the walls 13 is substantially a uniform distance a between 0 mm and 100 mm is formed. Thereafter, the vacuum drying chamber 6 is gas-tight by means of the doors 9, 10 closed and the pressure of about 1 bar ambient pressure lowered to 0.2 bar. After a predefined period, the vacuum drying chamber 6 is vented again and rinsed via the connection 18 with a flushing medium. The intermediate rinse causes residual moisture to be removed from the vacuum drying chamber 6. Then the vacuum drying chamber 6 is evacuated again. If necessary, the intermediate rinsing can be repeated. After the last evacuation process, the vacuum drying chamber 6 is ventilated and the dry machine part 2 is removed through the opened outlet opening 8.
