Description

Die Erfindung betrifft eine Vorrichtung sowie ein Verfahren zum Einbringen von Schüttgut -- insbesondere von Bremssand --aus einem Vorratsbehälter durch einen Förderschlauch mit Füllspitze in einen Verbraucher.The invention relates to a device and a method for the introduction of bulk material - especially of brake sand --aus a reservoir through a delivery hose with Filling tip in a consumer.

Beispielsweise durch die DE 24 43 552 C ist es bekannt, Schüttgüter mittels Fördereinrichtungen Verbrauchern zuzuteilen, etwa die Sandkästen von Schienenfahrzeugen mit Bremssand nachzufüllen. Für diese Aufgabe muss eine Zuteilvorrichtung in der Lage sein, wechselnde Mengen bis zu etwa 40 Litern Schüttgut je Zuteilvorgang abzugeben. Für den Fördervorgang von der Zuteilvorrichtung bis zum Sandkasten hat sich das seit vielen Jahren bekannte Schubförderverfahren durch mehrere Meter lange Schlauchleitungen bewährt. Hierbei bewegt sich der Sand als geschlossene Masse ohne Pfropfen und ohne zwischengelagerte Luftpolster durch die Förderleitung. Beim Schubförderverfahren werden nur geringe Luftmengen verbraucht, die Fördergeschwindigkeit ist sehr klein, es entstehen an flexiblen Förderleitungen keine schlagenden Bewegungen, und die geringen Förderluftmengen lassen sich mit geringem Aufwand am Sandbehälter fassen sowie einem Filter zuführen.For example, DE 24 43 552 C it is known To allocate bulk materials by means of conveyors to consumers such as the sandboxes of rail vehicles with brake sand refill. For this task must be an allocation device be able to change amounts up to about 40 liters To deliver bulk material per allocation process. For the conveying process from the metering device to the sandbox, this has become For many years known push conveyor by proven several meters long hose lines. Hereby moves the sand as a closed mass without grafting and without intermediate air cushion through the delivery line. At the Pushing processes use only small amounts of air, the conveying speed is very small, it arises on flexible conveyor lines no beating movements, and the low flow rates can be with little Take effort on sand container and a filter respectively.

Bei Zuteilvorrichtungen für Bremssand werden üblicherweise Schläuche als Förderleitungen zu den Sandkästen verwendet. Am sandkastenseitigen Schlauchende wird eine Füllspitze angebracht, die in geschlossener Stellung für Luft durchlässig ist, für Sand aber undurchlässig bleibt; dies ist erforderlich, damit der Sand beim Öffnen des Ventils an der Füllspitze ohne Stoß austritt. Füllspitzen dieser Art werden etwa in der Schrift zu DE 295 09 923 U1 beschrieben. With brake caliper allocators, it is common Hoses used as conveying pipes to the sandboxes. At the sandbox-side hose end, a filling tip is attached, in the closed position permeable to air is impermeable to sand but impermeable; this is required so that the sand when opening the valve at the Füllspitze exits without shock. Fill tips of this kind are about described in the document to DE 295 09 923 U1.

Bekannte Vorratsbehälter für Zuteilvorrichtungen sind als Druckbehälter ausgebildet. Bei jeder Entnahme wird der gesamte Vorratsbehälter -- unabhängig von der zuzuteilenden Sandmenge -- mit Druckluft aufgefüllt. Das Volumen des Vorratsbehälters ist bei stationären Zuteilvorrichtungen mindestens so groß wie die maximale Füllmenge eines Sandkastens. Üblich sind Druckbehälter mit etwa 100 Litern Volumen.Known storage containers for dispensing devices are known as Pressure vessel formed. With each removal becomes the entire Reservoir - regardless of the allocated Amount of sand - filled with compressed air. The volume of the reservoir is at least for stationary metering devices as large as the maximum capacity of a sandbox. Common are pressure vessels with about 100 liters volume.

Bei mobilen Zuteilvorrichtungen wird ein Sandvorrat für die Füllung mehrerer Sandkästen mitgeführt, wozu Druckbehälter mit 200 bis 500 Litern Volumen eingesetzt werden. Größere Volumina werden für Einheiten ausgewählt, die über einen Fahrantrieb verfügen.In mobile metering devices, a sand supply for the Filling several sand boxes carried, including pressure vessel be used with 200 to 500 liters volume. Larger volumes are selected for units that have one Travel drive.

Nach dem Stand der Technik wird nach jeder Füllung eines Sandbehälters die Druckluftzufuhr zum Vorratsbehälter unterbrochen und das nicht luftdichte Ventil der Füllspitze am Schlauchende geschlossen; durch dieses Ventil entweicht in den Pausen zwischen den Zuteilvorgängen die im Vorratsbehälter befindliche Druckluft. Beim nächsten Zuteilvorgang muss zum Druckaufbau die entwichene Luft nachgefüllt werden, d.h. ein Teil der Druckluft strömt ungenutzt ab.According to the prior art, after each filling of a Sand container the compressed air supply to the reservoir interrupted and the non airtight valve of the filling tip on Hose end closed; escapes through this valve in the breaks between the metering processes in the reservoir located compressed air. At the next allocation process must to relieve pressure, the escaped air is replenished, i. Part of the compressed air flows off unused.

Dies ist besonders bei mobilen Zuteilvorrichtungen problematisch, denn die Menge der in den Druckluftlaschen mitführbaren Druckluft, bzw. die Größe der Batterien zur Versorgung der zur Drucklufterzeugung notwendigen Kompressoren, sind durch mögliche Baugröße, Gewicht und Kosten eng begrenzt. Dazu kommt, dass das Gewicht der als Druckbehälter ausgeführten Vorratsbehälter infolge der notwendigen Wanddicken erheblich ist.This is particularly problematic in mobile metering devices, because the amount of carried in the compressed air straps Compressed air, or the size of the batteries for supply the necessary for compressed air compressors are limited by possible size, weight and cost. In addition, the weight of running as a pressure vessel Reservoir due to the necessary wall thickness considerably is.

In Kenntnis dieser Gegebenheiten hat sich der Erfinder das Ziel gesetzt, eine Vorrichtung und ein Verfahren für stationäre -- besonders aber für mobile -- Zuteilvorrichtungen zu schaffen, mit denen die beschriebenen Mängel beseitigt werden. In knowledge of these circumstances, the inventor has the Set goal, a device and a method for stationary - but especially for mobile - metering devices too to overcome the shortcomings described become.

Zur Lösung dieser Aufgabe führt die Lehre des unabhängigen Anspruches; die Unteransprüche geben günstige Weiterbildungen an. Zudem fallen in den Rahmen der Erfindung alle Kombinationen aus zumindest zwei der in der Beschreibung, der Zeichnung und/oder den Ansprüchen offenbarten Merkmale.To solve this task leads the doctrine of the independent claim; the dependent claims give favorable developments at. In addition, fall within the scope of the invention, all combinations from at least two of the description, the drawing and / or the features disclosed features.

Erfindungsgemäß ist zwischen dem Vorratsbehälter und der Füllspitze zumindest ein Schleusbehälter angeordnet und zwischen beiden Behältern wenigstens ein ihre Innenräume pneumatisch trennender Auslaufverschluss vorgesehen, über den der Vorratsbehälter mit dem Schleusbehälter verbindbar ist; letzterer wird mit einer Druckluftleitung verbunden und kann in Schließstellung des Auslaufverschlusses mit einem zum Umgebungsdruck höheren Druck versehen werden. Dazu hat es sich als günstig erwiesen, die Füllspitze durch den Förderschlauch mit dem Schleusbehälter zu verbinden.According to the invention between the reservoir and the Füllspitze arranged at least one lock container and between the two containers at least one of their interiors pneumatically separating outlet closure provided over the the reservoir is connectable to the lock container; the latter is connected to a compressed air line and can in the closed position of the outlet closure with a for Ambient pressure higher pressure. It has proved to be favorable, the filling tip through the Connecting the delivery hose with the lock container.

Das Schüttgut lagert also im Vorratsbehälter, dessen Innendruck sich dem Umgebungsdruck angleicht, und wird mittels eines kleineren druckbeaufschlagbaren Schleusenbehälters sowie der mit diesem gekoppelten Förderleitung dem zu füllenden Volumen pneumatisch zugefördert.The bulk material thus stored in the reservoir, its internal pressure is equal to the ambient pressure, and is by means of a smaller pressurizable lock container and coupled with this delivery line to be filled Volume supplied pneumatically.

Die Füllung eines Sandbehälters erfolgt dann durch mehrere Fördertakte des kleinen, leichten Schleusbehälters entsprechend den notwendigen Nachfüllungen. Druckluftverlust entsteht nur..noch beim letzten Fördertakt, wenn sich nach Abschluss der Druckluftzufuhr zum Schleusbehälter und dem Schließen des Ventils an der Füllspitze der Überdruck des kleinen Schleusbehälters entspannt.The filling of a sand tank then takes place through several Delivery cycle of the small, lightweight lock container accordingly the necessary refills. Compressed air loss arises only..but at the last promotion, if after graduation the compressed air supply to the lock container and the Closing the valve at the filling tip the overpressure of the relaxed small lock container.

Bei einem Schleusbehältervolumen von 5 Litern und einem Förderdruck von 1,5 bar bedeutet dies einen Luftverlust von max. 7,5 Litern. Demgegenüber würde ein 200-Liter-Vorratsbehälter entsprechend dem Stände der Technik einen Luftverlust von 300 Litern je Zuteilvorgang verursachen. With a lock container volume of 5 liters and a delivery pressure of 1.5 bar, this means an air loss of max. 7.5 liters. In contrast, a 200-liter reservoir according to the state of the art, an air loss of 300 Liters per metering operation.

Nach einem weiteren Merkmal der Erfindung ist dem Schleusraum des Schleusbehälters wenigstens ein Sensor als Fühlorgan für die Leerstellung zugeordnet, dank dessen die Fülltakte gesteuert zu werden vermögen. Dieser Sensor ist nahe eines Auslaufrohres des Schleusbehälters angeordnet, an das jener Förderschlauch angeschlossen wird.According to a further feature of the invention is the lock room of the lock container at least one sensor as a sensing element for assigned the empty position, thanks to which the filling cycles to be controlled. This sensor is close to one Outlet tube of the lock container arranged, to which Delivery hose is connected.

Als günstig hat es sich erwiesen, in einer Öffnung des Auslaufverschlusses einen quer zu deren Querschnitt bewegbaren Verschlusskörper vorzusehen. Diese Öffnung soll durchmesserveränderlich ausgebildet und von dem Verschlusskörper in Schließstellung abgedeckt sein. Zudem ist vorteilhafterweise der tellerartige Verschlusskörper durch eine Achse mit einem Pneumatikzylinder verbunden.As low it has been found in an opening of the outlet closure a transversely movable to the cross section Provide closure body. This opening should formed variable in diameter and of the Cover body to be covered in the closed position. In addition is Advantageously, the plate-like closure body an axle connected to a pneumatic cylinder.

Nach einem anderen Merkmal der Erfindung verläuft innerhalb der Öffnung des Auslaufverschlusses eine schlauchartig aufblasbare Membrane, die sich an den Umfang des tellerartigen Verschlusskörpers in dessen in jener Öffnung angeordneten Schließstellung anzulegen vermag.According to another feature of the invention proceeds within the opening of the outlet closure a tubular inflatable Membrane that sticks to the circumference of the plate-like Closure body in which arranged in that opening Closed position is able to create.

Der Schleusbehälter wird durch das zwischengefügte Ein- bzw. Auslaufventil starr oder flexibel mit dem Vorratsbehälter verbunden, so dass aus letzterem das Schüttgut dem Schleusbehälter zufließen kann. Der Vorratsbehälter kann staubdicht ausgeführt und mit einer ein Filterelement aufweisenden Abluftöffnung ausgestattet sein; durch das Filterelement kann nach jedem Schleustakt die Abluft geführt werden. Die mit dem Schüttgut strömende Förderluft kann am Sandbehälter aufgenommen und über eine beispielsweise mit der Förderleitung verbundenen Abluft- oder Rückführleitung auch jenem Filterelement zugeführt werden.The lock container is characterized by the interposed Ein- Outlet valve rigid or flexible with the reservoir connected, so that from the latter the bulk material the lock container can flow. The reservoir can be dustproof executed and with a filter element having exhaust port be equipped; through the filter element can the exhaust air is routed after each transfer cycle. The with the Bulk conveying air can be absorbed by the sand container and about one example with the delivery line connected exhaust or return line and that filter element be supplied.

Im Rahmen der Erfindung liegt zudem ein Verfahren zum Einbringen des Schüttgutes in den Verbraucher, bei dem der Innendruck des Vorratsbehälters auf den Umgebungsdruck eingestellt sowie der nachgeordnete Schleusbehälter mit Schüttgut aus dem Vorratsbehälter- gefüllt wird; anschließend werden die beiden Behälter voneinander pneumatisch getrennt und der Schleusbehälter mit höherem Druck beaufschlagt, wobei das Schüttgut durch den an den Schleusbehälter angefügten Förderschlauch dem zu füllenden Volumen pneumatisch zugefördert wird. Die mit dem Schüttgut strömende Förderluft soll an dem zu füllenden Volumen aufgenommen und über eine Abluftleitung einem Filterelement zugeführt werden.In the context of the invention, there is also a method for introducing of the bulk material to the consumer, in which the Internal pressure of the reservoir adjusted to the ambient pressure and the downstream lock container with bulk material is filled from the reservoir; then the two containers separated pneumatically from each other and the Locking container subjected to higher pressure, the Bulk material through the delivery hose attached to the lock container pneumatically fed to the volume to be filled becomes. The flowing with the bulk material conveying air should at the taken to be filled volume and an exhaust duct fed to a filter element.

Der Druckluftverlust bei nach diesem Verfahren arbeitenden Zuteilvorrichtungen ist so gering, dass sich mit kleinen Energiespeichern, die z.B. als Batterie oder als Hochdruckluftspeicher ausgeführt werden können, leichte, mobile Zuteilvorrichtungen bauen lassen, die sehr wirtschaftlich zu nutzen sind. Durch das geringe Gewicht kann oft auf einen teuren Fahrantrieb für die Mobilität der Zuteilvorrichtung verzichtet werden.The loss of compressed air when working by this method Dispensing devices is so small that with small Energy storage, e.g. as a battery or as high-pressure air storage can be carried out, light, mobile metering devices to build, which is very economical too use are. Due to the low weight can often be on one expensive travel drive for the mobility of the metering device be waived.

Stationäre Zuteilvorrichtungen werden üblicherweise nahe der Sandkastenposition aufgestellt. Mobile Einheiten werden nahe an die Einfüllöffnungen der Sandkästen gefahren. Die Füllspitze wird von Hand in die Einfüllöffnung geführt.Stationary metering devices are usually close to the Sandbox position set up. Mobile units are getting close moved to the filling openings of the sandboxes. The filling tip is guided by hand into the filling opening.

Dank des geringen Gewichtes der erfindungsgemäßen Vorrichtung kann diese auch mittels Positionierantrieb automatisch an die Einfüllöffnungen der Sandkästen geführt werden, wie es für Treibstofftankeinrichtungen zum Stand der Technik gehört. Dazu kann entweder der Schlauch mit der Füllspitze oder die gesamte Zuteilvorrichtung positioniert werden.Thanks to the low weight of the device according to the invention This can also be done automatically by means of positioning drive to the Filling holes of the sandboxes are led as it is for Fuel tank equipment belongs to the prior art. This can either the hose with the filling tip or the entire dispensing device are positioned.

Zuteilvorrichtungen nach dem erfindungsgemäßen Verfahren können für Bremssand, aber auch für andere Schüttgüter, verwendet werden. Ob der pneumatische Transport mit dem Schubförderverfahren oder einem andren pneumatischen Förderverfahren durchgeführt wird, richtet sich nach den Eigenschaften der zuzuteilenden Schüttgüter.Dispensing devices according to the inventive method Can be used for brake sand, but also for other bulk materials become. Whether the pneumatic transport with the Push conveying method or another pneumatic conveying method is performed depends on the characteristics the bulk materials to be allocated.

Von einem zentralen Silo aus können mehrere Zuteilvorrichtungen mit Schüttgut versorgt werden. From a central silo, several metering devices can be used be supplied with bulk material.
