Definitions
- the invention relates to a device for storing and possibly transporting workpieces, with at least one tubular container which has at least one receiving space for a workpiece, which can be introduced into the container through a loading opening.
- Devices of this type are required in in-house material flow systems, for the intermediate storage of workpieces in machining centers in which the individual stations work at different cycle rates, and for transport between different operating sites, and are known in a wide variety of embodiments.
- washing fluid e.g., before a machining operation
- cleaning a liquid or otherwise treating the surface of the workpieces for example painting the surface, sandblasting or subjecting the surface to a heat treatment.
- washing systems are generally currently used which have a basin into which a multiplicity of workpieces is placed, held by a carrier element, for example a mesh basket.
- a carrier element for example a mesh basket.
- the car washes currently used are not just that complex and thus expensive, but usually also require a large amount of cleaning fluid, so that they hardly work economically, especially in prototype production or in the production of small lot sizes.
- An example of such a single-purpose washing system, which is intended exclusively for instruments, is described in US Pat. No. 3,101,729, on which the preamble of claim 1 is based. This device is also not suitable for transporting or storing the instruments.
- the invention is based on the object of developing a device for the surface treatment of workpieces in such a way that workpieces can be processed economically and with a low outlay on processing fluid without expensive special systems, such as washing or painting systems.
- tubular containers are used in a number of cases, since a large number of such tubular containers can be easily handled and stored, for example in the form of coils or honeycombs. It is expressly pointed out that in the context of this description a tubular container is also understood to mean a container with an inner and / or outer contour that deviates from the circular shape. For example, the container can also have a hexagonal cross section.
- tubular or tubular containers can easily be modified so that they are suitable for flushing with the processing fluid "in the flow".
- the tubular container designed according to the invention - regardless of whether the tubular container can be opened for loading and unloading or whether the container is loaded via one or both end faces - has an opening in one end face of the container to which the processing device which supplies the machining fluid, is dockable, so that the machining fluid enters through this opening.
- This opening can be in particular the loading opening for the workpieces in the case of containers which can be loaded at the end (claim 4), while it is an additional opening in the case of hinged containers.
- an outlet opening for the fluid is provided, to which a fluid drain can be attached.
- the outlet opening can be this removal opening in the case of containers which are “fed” in the passage, ie in which the workpiece is introduced through an opening in one end face and removed through a removal opening in the other end face, so that it is not necessary in this case there should be any additional openings in the containers.
- the tubular container (s), which is already present in devices for storing (usually also simply a tube), is developed in such a way that the workpiece stored in it can be processed with a flowing fluid without removal from the tube.
- the device according to the invention can thus be integrated in machining centers in which the workpieces are machined with a specific machine cycle, for cleaning the workpieces in the machine cycle. Due to this integration in the machining center, it is not a problem if the washing time required for cleaning all workpieces takes a relatively long time compared to washing in a wire mesh box, for example.
- the processing device which has at least one fluid outlet connection for connecting at least one tube, can, for example, be a washing device which provides a washing liquid, a cleaning gas and / or a granulate (claim 3). It is preferred if, in addition to the cleaning fluid, which in particular can be any conventional washing liquid, the washing device according to claim 7 also has at least one further fluid, for example a rinsing liquid, with a fluid a different temperature and / or a drying fluid or gas, such as (hot) compressed air (claim 7), so that the workpiece is also dried.
- a washing device which provides a washing liquid, a cleaning gas and / or a granulate (claim 3). It is preferred if, in addition to the cleaning fluid, which in particular can be any conventional washing liquid, the washing device according to claim 7 also has at least one further fluid, for example a rinsing liquid, with a fluid a different temperature and / or a drying fluid or gas, such as (hot) compressed air (claim 7), so that the workpiece
- the processing device can also be any other fluid processing device that emits, for example, a spray jet, a sandblast or a hot air jet.
- a spray jet for example, a spray jet, a sandblast or a hot air jet.
- the term fluid not only means liquids, but also gases and granules, etc.
- the design according to the invention makes it possible to also treat the surface of the workpiece in the tubular container in which the workpiece is already stored for other reasons, for example for intermediate storage or for transport. Since the workpiece must already be placed in the container for the reasons mentioned, no additional handling operation of the workpiece is required to carry out the surface treatment process.
- machining fluid is low, since the containers for the workpiece holder are designed, for example, for reasons of storage space, in such a way that they enclose the workpiece comparatively closely.
- the device according to the invention thus not only has the advantage that the respective machining process can be carried out economically with little handling effort and material use, but also the advantage that the workpiece remains in place during all machining processes, so that the risk of workpiece damage is low.
- the inner surfaces of the container are also "washed" during a washing process, so that an additional cleaning process for the container is not necessary.
- the washing device has a further tube which is movable over the first tube or the receiving tube, it is also possible that in addition to cleaning the workpieces located in the first tube and the inner tube wall the outer tube wall is cleaned.
- a possibly already existing feed of the storage device for example a winding, cassette or honeycomb storage device that advances the individual containers of the storage device, can be used to successively move the individual containers not only into the area of a loading and unloading station , but also to advance into the area of the processing device.
- a suitable design of the processing device it can then automatically dock onto the container transferred into its area, so that a fully automatic processing process can be implemented with little effort using existing elements of the storage device (claim 13).
- a termination or Locking element can be used, which prevents the workpiece from being carried away by the machining fluid.
- This closure element can in particular be a grid (claim 6).
- guide devices such as guide plates, are provided in the container for guiding the machining fluid. These control devices can in particular cause a turbulent flow or a rotation of the fluid. These flow effects can be further enhanced by a pulsating flow of the fluid.
- the container or containers can carry out an intermittent movement and / or to rotate about at least one axis after the machining fluid has been introduced (claims 10 and 11, respectively).
- the container can in particular be designed such that it can be temporarily separated from the processing device without the fluid running out of the container.
- the outer shape of the container is optimized with regard to heat exchange with the environment. This can play a role in particular if a subsequent processing or drying process takes place, for example, in an oven.
- the machining process is a cleaning process without restricting the general inventive concept.
- other processing operations such as painting, sandblasting etc. are also possible.
- FIG. 1 shows an exemplary embodiment of the invention in which (at least) one tubular container 1 is provided, which can be loaded with at least one workpiece through one end face (FIG. 3) and unloaded through the other end face (FIG. 4).
- a washing device 2 can be docked onto the loading opening in one end face and has three inlet connections 7, 8 and 9, for example for a cleaning agent, a detergent and a drying agent, such as hot air, etc.
- a changeover valve 4 is provided for switching between the individual fluid inlet connections.
- a closure element 3 which on the one hand serves to receive the fluid after it has passed through the container 1 and, for example, to pass it to an outlet.
- a grid 6 is additionally inserted, which prevents the fluid from carrying the workpiece 5 out of the container.
- the washing device 2 For loading the container 1 with a workpiece 5, the washing device 2 can be removed (FIG. 3), while the end element 3 is designed to be removable for removing the workpiece 5 from the container 1 (FIG. 4).
- FIG. 2 shows a second embodiment of the invention, in which the container 1 is divided and has two halves 1a and 1b. Again, an inlet and an outlet for the cleaning fluid are provided in the end faces of the container.
- the washing device shown in FIG. 1 can be docked to the inlet; in the outlet, next to the grille 6, which prevents the workpiece 5 from being carried out, there is an outlet, also not shown in FIG. 2, which allows the fluid to be collected.
- processing device can have one container or several or all containers be connected at the same time. If necessary, several machining devices can also be present in order to be able to carry out one machining operation or several machining operations simultaneously on several workpieces:
- one tube in each case is located in the area of a washing device and one tube, the contents of which have already been washed, in the area of a drying device.
- the individual processing devices are preferably designed so that the processing device automatically connects to the respective tube.

Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Speichern sowie gegebenenfalls Transportieren von Werkstücken, mit mindestens einem rohrförmigen Behälter, der wenigstens einen Aufnahmeplatz für ein Werkstück aufweist, das durch eine Beladeöffnung in den Behälter einbringbar ist.The invention relates to a device for storing and possibly transporting workpieces, with at least one tubular container which has at least one receiving space for a workpiece, which can be introduced into the container through a loading opening.
Derartige Vorrichtungen werden in innerbetrieblichen Materialfluß-Systemen, zur zwischenspeicherung von Werkstücken in Bearbeitungszentren, bei denen die einzelnen Stationen mit unterschiedlichen Taktraten arbeiten, sowie zum Transport zwischen verschiedenen Betriebsstätten benötigt, und sind in vielfältigen Ausführungsformen bekannt.Devices of this type are required in in-house material flow systems, for the intermediate storage of workpieces in machining centers in which the individual stations work at different cycle rates, and for transport between different operating sites, and are known in a wide variety of embodiments.
Nun ist es häufig erforderlich, Werkstücke vor einem Bearbeitungsvorgang, vor der Zwischenspeicherung oder vor dem Transport zu einer anderen Betriebsstätte beispielsweise mit einem Waschfluid, z.B. einer Flüssigkeit zu reinigen oder in anderer Weise die Oberfläche der Werkstücke zu behandeln, beispielsweise die Oberfläche zu lackieren, sandzustrahlen oder die Oberfläche einer Wärmebehandlung zu unterziehen.Now it is often necessary to wash workpieces with a washing fluid, e.g., before a machining operation, before being temporarily stored or before being transported to another facility. cleaning a liquid or otherwise treating the surface of the workpieces, for example painting the surface, sandblasting or subjecting the surface to a heat treatment.
Für die Reinigung von Werkstücken werden derzeit in der Regel Waschanlagen eingesetzt, die ein Bassin aufweisen, in das eine Vielzahl von Werkstücken gehalten von einem Trägerelement, beispielsweise einem Gitterkorb, eingelegt wird. Die derzeit verwendeten Waschanlagen sind nicht nur aufwendig und damit teuer, sondern erfordern in der Regel auch einen großen Einsatz an Reinigungsflüssigkeit, so daß sie insbesondere in der Prototypenfertigung oder bei der Fertigung kleiner Losgrößen kaum ökonomisch arbeiten. Ein Beispiel für eine derartige Einzweck-Waschanlage, die ausschließlich für Instrumente gedacht ist, ist in der USA-3 101 729, auf die sich der Oberbegriff des Anspruchs 1 stützt, beschrieben. Diese Vorrichtung ist darüberhinaus nicht zum Transportieren oder Speichern der Instrumente geeignet.For the cleaning of workpieces, washing systems are generally currently used which have a basin into which a multiplicity of workpieces is placed, held by a carrier element, for example a mesh basket. The car washes currently used are not just that complex and thus expensive, but usually also require a large amount of cleaning fluid, so that they hardly work economically, especially in prototype production or in the production of small lot sizes. An example of such a single-purpose washing system, which is intended exclusively for instruments, is described in US Pat. No. 3,101,729, on which the preamble of claim 1 is based. This device is also not suitable for transporting or storing the instruments.
Darüberhinaus ist es zur Durchführung des Waschvorganges erforderlich, das Werkstück aus einem Zwischenspeicher zu entnehmen, es in das Trägerelement einzulegen, anschließend wieder aus dem Trägerelement zu entnehmen und in den gleichen oder einen anderen Zwischenspeicher einzubringen. Dieser Vorgang erfordert einen großen Arbeitsaufwand, der insbesondere bei kleinen Losgrößen nur schwer zu automatisieren ist, so daß vergleichsweise große Kosten entstehen, die häufig die Kosten für das eigentliche Reinigungsfluid um ein Vielfaches übertreffen.In addition, in order to carry out the washing process, it is necessary to remove the workpiece from an intermediate store, insert it into the carrier element, then remove it again from the carrier element and insert it into the same or a different intermediate store. This process requires a large amount of work, which is difficult to automate, particularly in the case of small batch sizes, so that comparatively large costs arise, which often exceed the costs for the actual cleaning fluid many times over.
Ähnliches gilt für Lackier-, Sandstrahl- bzw. andere Oberflächen-Bearbeitungsvorgänge, bei denen die Oberfläche beispielsweise einer Temperaturbehandlung durch Heißluft unterzogen wird.The same applies to painting, sandblasting or other surface processing operations in which the surface is subjected, for example, to heat treatment by hot air.
2er Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Oberflächenbehandlung von Werkstücken dahingehend weiterzubilden, daß Werkstücke ökonomisch und mit einem geringen Aufwand an Bearbeitungsfluid ohne teure spezielle Anlagen, wie beispielsweise Wasch- oder Lackieranlagen bearbeitet werden können.The invention is based on the object of developing a device for the surface treatment of workpieces in such a way that workpieces can be processed economically and with a low outlay on processing fluid without expensive special systems, such as washing or painting systems.
Eine erfindungsgemäße Lösung dieser Aufgabe ist im Anspruch 1 angegeben.An inventive solution to this problem is specified in claim 1.
Zur Lösung der gestellten Aufgabe geht die Erfindung von dem Grundgedanken aus, daß es aus den eingangs erläuterten Gründen häufig erforderlich ist, die Werkstücke in speziellen Behältern zwischenzuspeichern bzw. zu transportieren. Dabei werden in einer Reihe von Fällen rohrförmige Behälter verwendet, da sich eine Vielzahl derartiger rohrförmiger Behälter beispielsweise in Form von Wickeln oder Waben leicht handhaben und speichern läßt. Ausdrücklich wird darauf verwiesen, daß im Rahmen dieser Beschreibung unter einem rohrförmigen Behälter auch ein Behälter mit einer Innen- und/oder Außenkontur verstanden wird, die von der Kreisform abweicht. Beispielsweise kann der Behälter auch einen sechseckigen Querschnitt haben.To achieve the object, the invention is based on the basic idea that, for the reasons explained at the outset, it is often necessary to temporarily store or transport the workpieces in special containers. Tubular containers are used in a number of cases, since a large number of such tubular containers can be easily handled and stored, for example in the form of coils or honeycombs. It is expressly pointed out that in the context of this description a tubular container is also understood to mean a container with an inner and / or outer contour that deviates from the circular shape. For example, the container can also have a hexagonal cross section.
Erfindungsgemäß ist nun erkannt worden, daß sich derartige rohrförmige bzw. rohrartige Behälter leicht so modifizieren lassen, daß sie sich zum Spülen mit dem Bearbeitungsfluid "im Durchstrom" eignen. Hierzu weist der erfindungsgemäß ausgebildete rohrförmige Behälter - unabhängig davon, ob der rohrförmige Behälter zum Be- und Entladen aufklappbar ist, oder ob der Behälter über eine oder beide Stirnseiten beschickt wird - in einer Stirnseite des Behälters eine Öffnung auf, an die die Bearbeitungseinrichtung, die das Bearbeitungsfluid liefert, andockbar ist, so daß durch diese Öffnung das Bearbeitungsfluid eintritt. Diese Öffnung kann bei Behältern, die stirnseitig beschickbar sind, insbesondere die Beladeöffnung für die Werkstücke sein (Anspruch 4), während sie bei aufklappbaren Behältern eine zusätzliche Öffnung ist.According to the invention it has now been recognized that such tubular or tubular containers can easily be modified so that they are suitable for flushing with the processing fluid "in the flow". For this purpose, the tubular container designed according to the invention - regardless of whether the tubular container can be opened for loading and unloading or whether the container is loaded via one or both end faces - has an opening in one end face of the container to which the processing device which supplies the machining fluid, is dockable, so that the machining fluid enters through this opening. This opening can be in particular the loading opening for the workpieces in the case of containers which can be loaded at the end (claim 4), while it is an additional opening in the case of hinged containers.
In der anderen Stirnseite ist unabhängig davon, ob die Rohre durch Aufklappen oder durch eine Stirnseite beschickt werden, eine Austrittsöffnung für das Fluid vorgesehen, an der eine Fluid-Ableitung anbringbar ist. Die Austrittsöffnung kann bei Behältern, die im Durchlauf "beschickt" werden, d.h. bei denen das Werkstück durch eine Öffnung in der einen Stirnfläche eingebracht und durch eine Entnahmeöffnung in der anderen Stirnfläche entnommen wird, diese Entnehmeöffnung sein, so daß es in diesem Falle nicht erforderlich iste irgendwelche zusätzliche Öffnungen in den Behältern vorzusehen.In the other face it is independent of whether the Tubes are loaded by opening or through an end face, an outlet opening for the fluid is provided, to which a fluid drain can be attached. The outlet opening can be this removal opening in the case of containers which are “fed” in the passage, ie in which the workpiece is introduced through an opening in one end face and removed through a removal opening in the other end face, so that it is not necessary in this case there should be any additional openings in the containers.
Durch diese Ausbildung werden der bzw. die in Vorrichtungen zum Speichern ohnehin vorhandenen rohrförmigen Behälter (i.f. auch einfach Rohr) derart weitergebildet, daß das in ihnen gespeicherte Werkstück ohne Entnahme aus dem Rohr mit einem durchströmenden Fluid bearbeitet werden kann. Die erfindungsgemäße Vorrichtung kann damit in Bearbeitungszentren integriert werden, in denen die Werkstücke mit einem bestimmten Maschinentakt bearbeitet werden, zur Reinigung der Werkstücke im Maschinentakt. Aufgrund dieser Integration in das Bearbeitungszentrum ist es nicht störend, wenn die für die Reinigung sämtlicher Werkstücke erforderliche Waschzeit verglichen mit dem Waschen beispielsweise in einer Gitterbox relativ lange dauert.With this design, the tubular container (s), which is already present in devices for storing (usually also simply a tube), is developed in such a way that the workpiece stored in it can be processed with a flowing fluid without removal from the tube. The device according to the invention can thus be integrated in machining centers in which the workpieces are machined with a specific machine cycle, for cleaning the workpieces in the machine cycle. Due to this integration in the machining center, it is not a problem if the washing time required for cleaning all workpieces takes a relatively long time compared to washing in a wire mesh box, for example.
Die Bearbeitungseinrichtung, die wenigstens einen Fluid-Ausgangsanschluß zum Anschluß mindestens eines Rohres aufweist, kann.beispielsweise eine Wascheinrichtung sein, die eine Waschflüssigkeit, ein Reinigungsgas und/oder ein Granulat bereitstellt (Anspruch 3). Dabei ist es bevorzugt, wenn die Wascheinrichtung nach Anspruch 7 zusätzlich zu dem Reinigungsfluid, das insbesondere jede herkömmliche Waschflüssigkeit sein kann, zumindest noch ein weiteres Fluid, beispielsweise eine Spülflüssigkeit, ein Fluid mit einer anderen Temperatur und/oder ein Trocknungsfluid bzw. -gas, wie beispielsweise (heiße) Druckluft (Anspruch 7) liefert, so daß das Werkstück auch getrocknet wird.The processing device, which has at least one fluid outlet connection for connecting at least one tube, can, for example, be a washing device which provides a washing liquid, a cleaning gas and / or a granulate (claim 3). It is preferred if, in addition to the cleaning fluid, which in particular can be any conventional washing liquid, the washing device according to
Selbstverständlich kann die Bearbeitungseinrichtung aber auch jede andere Fluid-Bearbeitungseinrichtung sein, die beispielsweise einen Lackierstrahl, einen Sandstrahl oder einen Heißluftstrahl abgibt. Ausdrücklich wird darauf verwiesen, daß im Rahmen dieser Beschreibung unter dem Begriff Fluid nicht nur Flüssigkeiten, sondern auch Gase und Granulate etc verstanden werden.Of course, the processing device can also be any other fluid processing device that emits, for example, a spray jet, a sandblast or a hot air jet. It is expressly pointed out that in the context of this description the term fluid not only means liquids, but also gases and granules, etc.
In jedem Falle ist es durch die erfindungsgemäße Ausbildung möglich, in dem rohrförmigen Behälter, in dem das Werkstück aus anderen Gründen - beispielsweise zur Zwischenspeicherung oder zum Transport - bereits gespeichert ist, auch die Oberfläche des Werkstücks zu behandeln. Da das Werkstück aus den genannten Gründen bereits in den Behälter eingebracht werden muß, ist zur Durchführung des Oberflächen-Behandlungsvorganges kein zusätzlicher Handhabungsvorgang des Werkstücks erforderlich.In any case, the design according to the invention makes it possible to also treat the surface of the workpiece in the tubular container in which the workpiece is already stored for other reasons, for example for intermediate storage or for transport. Since the workpiece must already be placed in the container for the reasons mentioned, no additional handling operation of the workpiece is required to carry out the surface treatment process.
Zudem ist der Materialeinsatz an Bearbeitungsfluid gering, da die Behälter zur Werkstückaufnahme beispielsweise bereits aus Gründen des Speicherraums so ausgebildet sind, daß sie das Werkstück vergleichsweise eng umschließen.In addition, the use of machining fluid is low, since the containers for the workpiece holder are designed, for example, for reasons of storage space, in such a way that they enclose the workpiece comparatively closely.
Die erfindungsgemäße Vorrichtung hat damit nicht nur den Vorteil, daß in ihr der jeweilige Bearbeitungsvorgang ökonomisch mit geringem Handhabungsaufwand und Materialeinsatz ausgeführt werden kann, sondern auch den Vorteil, daß das Werkstück während allen Bearbeitungsvorgängen an seinem Ort bleibt, so daß die Gefahr einer Werkstück-Beschädigung gering ist.The device according to the invention thus not only has the advantage that the respective machining process can be carried out economically with little handling effort and material use, but also the advantage that the workpiece remains in place during all machining processes, so that the risk of workpiece damage is low.
Darüberhinaus werden beispielsweise bei einem Waschvorgang auch die Innenflächen des Behälters "mitgewaschen", so daß ein zusätzlicher Reinigungsvorgang für den Behälter entfällt. Bei der im Anspruch 15 angegebenen Weiterbildung, bei der die Wascheinrichtung ein weiteres Rohr aufweist, das über das das oder die Werkstücke aufnehmende erste Rohr bewegbar ist, ist es darüberhinaus möglich, daß zusätzlich zur Reinigung der in dem ersten Rohr befindenden Werkstücke und der Rohrinnenwand auch die Rohraußenwand gereinigt wird.In addition, for example, the inner surfaces of the container are also "washed" during a washing process, so that an additional cleaning process for the container is not necessary. In the development specified in claim 15, in which the washing device has a further tube which is movable over the first tube or the receiving tube, it is also possible that in addition to cleaning the workpieces located in the first tube and the inner tube wall the outer tube wall is cleaned.
Vor allem aber kann ein eventuell bereits vorhandener Vorschub der Speichervorrichtung, also beispielsweise eines Wickel-, Kasetten- oder Wabenspeichers, der die einzelnen Behälter der Speichervorrichtung vorschiebt, dazu benutzt werden, um nacheinander die einzelnen Behälter nicht nur in den Bereich einer Be- und Entladestation, sondern auch in den Bereich der Bearbeitungseinrichtung vorzuschieben. Bei geeigneter Ausbildung der Bearbeitungseinrichtung kann sich diese dann selbsttätig an den jeweils in ihren Bereich überführten Behälter andocken, so daß mit geringem Aufwand unter Verwendung vorhandener Elemente der Speichereinrichtung ein vollautomatischer Bearbeitungsvorgang realisiert werden kann (Anspruch 13).Above all, however, a possibly already existing feed of the storage device, for example a winding, cassette or honeycomb storage device that advances the individual containers of the storage device, can be used to successively move the individual containers not only into the area of a loading and unloading station , but also to advance into the area of the processing device. With a suitable design of the processing device, it can then automatically dock onto the container transferred into its area, so that a fully automatic processing process can be implemented with little effort using existing elements of the storage device (claim 13).
Bei einer anderen, im Anspruch 14 angegebenen Ausgestaltung, die insbesondere bei zu einer Wabe zusammengefaßten Rohren von Vorteil ist, können mehrere oder alle Rohre gleichzeitig mit der Bearbeitungseinrichtung derart verbunden werden, daß die in den mit der Bearbeitungseinrichtung verbundenen Rohren befindlichen Werkstücke gleichzeitig mit dem Bearbeitungsfluid beaufschlagbar sind.In another embodiment specified in claim 14, which is particularly advantageous for tubes combined to form a honeycomb, several or all tubes can be connected to the processing device at the same time in such a way that the workpieces located in the pipes connected to the processing device are simultaneously with the processing fluid are acted upon.
Um insbesondere dann, wenn das Werkstück durch eine Stirnseite eingesetzt und durch die andere Stirnseite entnommen wird, ein Austragen des Werkstücks durch die Entnahmeöffnung aufgrund des strömenden Bearbeitungsfluids zu verhindern, ist es weiterhin gemaß Anspruch 5 von Vorteil, wenn in die Entnahmeöffnung ein Abschluß- bzw. Sperrelement einsetzbar ist, das ein Austragen des Werkstücks durch das Bearbeitungsfluid verhindert. Dieses Abschlußelement kann insbesondere ein Gitter sein (Anspruch 6).In order to prevent discharge of the workpiece through the removal opening due to the flowing machining fluid, in particular when the workpiece is inserted through one end side and removed through the other end side, it is furthermore advantageous according to
Um den Bearbeitungsvorgang und insbesondere einen Reinigungsvorgang weiter zu verbessern, ist es gemäß Anspruch 9 bevorzugt, wenn in dem Behälter Leiteinrichtungen, wie Leitbleche zum Leiten des Bearbeitungsfluids vorgesehen sind. Diese Leiteinrichtungen könne insbesondere eine turbulente Strömung oder eine Rotation des Fluids hervorrufen. Diese Strömungseffekte können durch eine pulsierende Strömung des Fluids weiter verstärkt werden.In order to further improve the machining process and in particular a cleaning process, it is preferred according to claim 9 if guide devices, such as guide plates, are provided in the container for guiding the machining fluid. These control devices can in particular cause a turbulent flow or a rotation of the fluid. These flow effects can be further enhanced by a pulsating flow of the fluid.
Ferner ist es möglich, daß nach dem Einleiten des Bearbeitungsfluids der oder die Behälter um wenigstens eine Achse eine intermittierende Bewegung ausführen und/oder rotieren (Ansprüche 10 bzw. 11). Hierzu kann der Behälter insbesondere so gestaltet sein, daß er vorübergehend von der Bearbeitungseinrichtung trennbar ist, ohne daß das Fluid aus dem Behälter ausläuft.Furthermore, it is possible for the container or containers to carry out an intermittent movement and / or to rotate about at least one axis after the machining fluid has been introduced (
Ferner ist es gemäß Anspruch 12 möglich, daß die Außenform des Behälters bezüglich Wärmeaustausch mit der Umgebung optimiert ist. Dies kann insbesondere dann eine Rolle spielen, wenn ein nachfolgender Bearbeitungsvorgang oder Trocknungsvorgang beispielsweise in einem Ofen erfolgt.Furthermore, it is possible according to claim 12 that the outer shape of the container is optimized with regard to heat exchange with the environment. This can play a role in particular if a subsequent processing or drying process takes place, for example, in an oven.
Die Erfindung wird nachstehend ohne Beschränkung des allgemeinen Erfindungsgedankens anhand von Ausführungsbeispielen unter Bezugnahme auf die Zeichnung exemplarisch beschrieben, auf die im übrigen bezüglich der Offenbarung aller im Text nicht näher erläuterten erfindungsgemäßen Einzelheiten ausdrücklich verwiesen wird.

In den Figuren ist ohne Beschränkung des allgemeinen Erfindungsgedankens der Bearbeitungsvorgang ein Reinigungsvorgang. Selbstverständlich sind aber auch andere Bearbeitungsvorgänge, wie Lackieren, Sandstrahlen etc. möglich.In the figures, the machining process is a cleaning process without restricting the general inventive concept. Of course, other processing operations such as painting, sandblasting etc. are also possible.
Figur 1 zeigt ein Ausführungsbeispiel der Erfindung, bei dem (mindestens) ein rohrförmiger Behälter 1 vorgesehen ist, der durch eine Stirnseite mit wenigstens einem Werkstück beladen (Figur 3) und durch die andere Stirnseite entladen (Figur 4) werden kann.FIG. 1 shows an exemplary embodiment of the invention in which (at least) one tubular container 1 is provided, which can be loaded with at least one workpiece through one end face (FIG. 3) and unloaded through the other end face (FIG. 4).
An die Beladeöffnung in der einen Stirnseite ist eine Wascheinrichtung 2 andockbar, die drei Einlaufstutzen 7, 8 und 9 beispielsweise für ein Reinigungsmittel, ein Spülmittel und ein Trocknungsmittel, wie Heißluft etc. aufweist. Zur Umschaltung zwischen den einzelnen Fluid-Einlaufstutzen ist ein Umschaltventil 4 vorgesehen. An der Auslaßöffnung des Behälters 1 befindet sich ein Abschlußelement 3, das zum einen dazu dient, das Fluid nach Durchlauf durch den Behälter 1 aufzunehmen und beispielsweise einem Ablauf zuzuleiten. In das Abschlußelement 3 ist zusätzlich ein Gitter 6 eingesetzt, das verhindert, daß das Fluid das Werkstück 5 aus dem Behälter austrägt.A
Zum Beschicken des Behälters 1 mit einem Werkstück 5 ist die Wascheinrichtung 2 abnehmbar (Figur 3), während zur Entnahme des Werkstücks 5 aus dem Behälter 1 das Abschlußelement 3 abnehmbar gestaltet ist (Figur 4).For loading the container 1 with a

Vorstehend ist die Erfindung anhand eines Ausführungsbeispiels ohne Beschränkung des allgemeinen Erfindungsgedankens beschrieben worden, innerhalb dessen selbstverständlich die verschiedensten Modifikationen möglich sind:The invention has been described above using an exemplary embodiment without restricting the general inventive concept, within which, of course, the most varied modifications are possible:
Beispielsweise ist in den Figuren nur eine Bearbeitungsvorrichtung und ein rohrförmiger Behälter dargestellt. Die erfindungsgemäßen Grundgedanken können selbstverständlich auch bei Vorrichtungen zum Speichern angewendet werden, bei denen eine Vielzahl von rohrförmigen Behältern vorhanden sind, also beispielweise bei Wickel-, Kasetten und/oder Wabenspeichern. Dabei kann die Bearbeitungseinrichtung mit einem Behälter oder mit mehreren oder allen Behältern gleichzeitig verbunden sein. Gegebenenfalls können auch mehrere Bearbeitungseinrichtungen vorhanden sein, um an mehreren Werkstücken gleichzeitig einen Bearbeitungsvorgang oder mehrere Bearbeitungsvorgänge ausführen zu können:For example, only one processing device and a tubular container are shown in the figures. The basic ideas according to the invention can of course also be applied to devices for storage in which a multiplicity of tubular containers are present, that is to say, for example, in winding, cassettes and / or honeycomb stores. The processing device can have one container or several or all containers be connected at the same time. If necessary, several machining devices can also be present in order to be able to carry out one machining operation or several machining operations simultaneously on several workpieces:
Beispielsweise ist es bei einer Vorrichtung, bei der eine Reihe von Rohren vorgesehen sind, die eine Vorschubeinheit vorschiebt, möglich, daß sich jeweils ein Rohr im Bereich einer Wascheinrichtung und ein Rohr, dessen Inhalt bereits gewaschen worden ist, im Bereich einer Trocknungseinrichtung befindet. Die einzelnen Bearbeitungseinrichtungen sind dabei bevorzugt so ausgebildet, daß sich die Bearbeitungseinrichtung selbsttätig mit dem jeweiligen Rohr verbindet.For example, in a device in which a series of tubes are provided which feed a feed unit, it is possible for one tube in each case to be located in the area of a washing device and one tube, the contents of which have already been washed, in the area of a drying device. The individual processing devices are preferably designed so that the processing device automatically connects to the respective tube.
