Definitions
- the invention relates to a suction device according to the preamble of claim 1.
- a suction device of the aforementioned type in which the suction vehicle is mechanically connected to the assigned motor vehicle by a coupling during suction, ie during its movement through the suction slot channel. In this way, the movement with the first conveyor or with the motor vehicle is ensured.
- a mechanical clutch is labor intensive and can lead to damage to the motor vehicle.
- the invention is therefore based on the object to provide a suction device of the type mentioned, in which a mechanical clutch, i.e. a forced coupling between the motor vehicle and vacuum truck is no longer required.
- each suction vehicle can be automatically moved to the exhaust of the respective motor vehicle by means of a suitable control so that the task of suctioning is reliably accomplished and damage to the motor vehicle is avoided.
- the "connection" to the exhaust and the separation from it in the area of the intake port run completely automatically. Operator intervention is not required.
- the device is configured as protected in claim 2. Due to the individual switching sections of the busbar, the vacuum trucks can be controlled, i.e. stopped or moved as necessary to establish the connection of the suction hood with the corresponding exhaust and after moving over the area of the suction slot channel, this connection, which, as said, has no mechanical coupling, again.
- the individual switching sections of the busbar are supplied with the corresponding switching pulses by a central control unit, i.e. when an electromagnet controls the engagement with the dogs, the corresponding section is energized to make the connection and de-energized to disconnect the connection. This is preferably a low-current supply of, for example, 24 volts.
- the suction device is advantageously designed in such a way that as stated in claim 3.
- the switching sections are correspondingly short in order to trigger the necessary control processes here (claim 6).
- the suction device is advantageously designed as provided in claim 7 in order to drive the suction vehicle for connection to the motor vehicle to this or to the exhaust and to ensure a separation again after the suction has taken place.
- a stop section is provided in front of the extension section (claim 9), in order to ensure a safe separation of the exhaust and exhaust hood.
- the suction device shown in the drawing is used to extract exhaust gases from motor vehicles which carry out a test run when moved by their conveyor 1 over a test track.
- the suction trolleys must be "connected" to the exhaust of the corresponding motor vehicle when moving over this test section in such a way that a safe extraction takes place.
- the motor vehicles are moved over a platform 2 by a first conveyor 1, in this case a overhead conveyor.
- the platform 2 has a slot in this area, under which a suction slot channel 4 is arranged, which lies between rails 3, which, as can be seen in FIG. 2, has an endless, i.e. form a closed oval.
- the return of the rails 3 is designated 5.
- the suction slot channel 4 with its rails 3 is at a higher level than the return.
- An entry section 6 leads to this higher level and an exit section 7 leads down from this level.
- a busbar 8 is provided parallel to the rail 3 for the suction vehicle 20 (see FIG. 3). This track is out.
- Carriers 10 for the individual suction vehicles 20 are provided on the second conveyor 9.
- the suction car 20 consist of a frame 25 on which the rollers 24 are mounted. These rollers 24 run on the rails 3, as can be seen in particular in FIG. 1.
- Each suction truck has a suction nozzle 22 which is connected to a suction hood 21 which projects beyond this through a slot in the platform 2 and onto the level of the exhaust pipe of the motor vehicle.
- the suction nozzle 22 passes through an elastic lip seal 23 of the fixed suction slot channel 4 and opens it, thus establishing the connection with the negative pressure within the suction slot channel 4.
- the suction slot channel 4 lies in the test area of the rail 3 between it (FIG. 3) and at a higher level (FIG. 2).
- An electromagnet 29 is located on the frame 25 in a housing 28. This electromagnet actuates a pawl 30, the two positions of this pawl 13 being shown in FIG. 1.
- the electromagnet is connected via electrical lines 27 to contacts 26 which engage in the busbar 8. It can easily be seen that the clinker 30, depending on whether the electromagnet 29 is energized or de-energized, occupies a position in which an engagement with a driver 10 is established and a different position in which the connection is closed the second conveyor 9 is interrupted.
- the busbar is divided into individual, electrically separate switching sections that can be switched on and off independently of one another. Some of these are shown in Fig. 3 and designated 14 to 19.
- the switching sections 14 to 16 form a buffer zone in which the suction vehicles are made available before coupling.
- the last switching section 14 in the conveying direction is the starting section.
- the corresponding suction vehicle 20 is started exactly at the point in time which ensures that it connects to the associated exhaust when starting up on the entry section 6.
- a special combination and arrangement of sensors and switches enables the vehicle length to be queried and provides the start signal for the vacuum truck at the start. It is therefore possible to start a vacuum truck for any vehicle at the right moment.
- a photocell (reflection light sensor) 31 is provided on each suction vehicle 20, which, when approaching a preceding or standing suction vehicle, ensures that the pawl of its suction vehicle is separated from the driver and thus the movement is interrupted. This is preferably done in the buffer zone.
- a lock 13 In the conveying direction in front of the buffer zone, a lock 13 is provided which has a section of the rails 3 in the return 5, which can be moved out laterally in order to carry out the suction or discharge of suction vehicles onto a repair rail 12 or a shunting rail 11.
- short switching sections 18, 19 are also provided for the busbar 8 in order to carry out the corresponding control pulses.
- the lock is preferably moved pneumatically. Suction vehicles are discharged for repair or maintenance purposes, for example.
- a special sensor system checks the upper part of the suction vehicle for correct seating on the lower part of the suction vehicle. If the position of the upper part to the lower part is shifted towards each other, this is recognized and the defective vacuum truck is automatically removed.
- a stop section with a corresponding switching section 17 is provided in the busbar 8 in order to ensure that the suction vehicles stop briefly and thus ensure a safe disconnection from the exhaust before moving to the lower level in the return section.
- a vacuum truck is in the start position in the switching section 14.
- the electromagnet 29 on this vacuum truck 20 is supplied with power and the second conveyor moves the vacuum truck precisely in synchronism with the vehicle so that it is connected to the exhaust after the start-up section 7, ie that the suction hood 21 slides over the exhaust.
- the suction vehicles standing in the buffer zone are moved accordingly in the conveying direction so that the next suction vehicle is ready in the starting position.
- the separation takes place accordingly, in particular by means of a “stop signal” for the switching section 17 of the busbar 8, and thus for a brief interruption in the movement of the suction vehicle for separation.
- the suction car is moved back in the direction 5 towards the buffer zone. Possibly. it can be removed in the lock 13 if this is required for repair or maintenance purposes.
- the suction hood is connected to the associated suction truck by a mechanically separable safety coupling (ball catch), so that these parts are mechanically separated, for example when hitting an obstacle.

Die Erfindung betrifft eine Absaugvorrichtung nach dem Oberbegriff des Anspruches 1.The invention relates to a suction device according to the preamble of claim 1.
Aus der DE-PS 35 25 293 ist eine Absaugvorrichtung der vorstehend genannten Art bekannt, bei der der Saugwagen bei Absaugung, d.h. also während seiner Bewegung durch den Saugschlitzkanal, mit dem zugeordneten Kraftfahrzeug mechanisch durch eine Kupplung verbunden wird. Auf diese Weise wird die Bewegung mit dem ersten Förderer oder mit dem Kraftfahrzeug sichergestellt. Eine derartige mechanische Kupplung ist arbeitsaufwendig und sie kann zu Beschädigungen an dem Kraftfahrzeug führen.From DE-PS 35 25 293 a suction device of the aforementioned type is known, in which the suction vehicle is mechanically connected to the assigned motor vehicle by a coupling during suction, ie during its movement through the suction slot channel. In this way, the movement with the first conveyor or with the motor vehicle is ensured. Such a mechanical clutch is labor intensive and can lead to damage to the motor vehicle.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Absaugvorrichtung der eingangs genannten Art zu schaffen, bei der eine mechanische Kupplung, d.h. eine Zwangskupplung zwischen Kraftfahrzeug und Saugwagen nicht mehr erforderlich ist.The invention is therefore based on the object to provide a suction device of the type mentioned, in which a mechanical clutch, i.e. a forced coupling between the motor vehicle and vacuum truck is no longer required.
Diese Aufgabe wird grundsätzlich durch das Kennzeichen des Anspruches 1 gelöst.This object is basically achieved by the characterizing part of claim 1.
Dadurch, daß erfindungsgemäß ein zweiter Förderer für die Saugwagen vorgesehen ist, kann jeder Saugwagen durch eine geeignete Steuerung so automatisch an den Auspuff des jeweiligen Kraftfahrzeuges bewegt werden, daß die Aufgabe des Absaugens sicher erfüllt und eine Beschädigung des Kraftfahrzeuges vermieden wird. Gleichzeitig läuft die "Verbindung" mit dem Auspuff und die Trennung von diesem im Bereich des Saugschlitzkanales vollständig automatisch ab. Ein Eingreifen von Bedienungspersonen ist nicht erforderlich.The fact that, according to the invention, a second conveyor is provided for the suction vehicle, each suction vehicle can be automatically moved to the exhaust of the respective motor vehicle by means of a suitable control so that the task of suctioning is reliably accomplished and damage to the motor vehicle is avoided. At the same time, the "connection" to the exhaust and the separation from it in the area of the intake port run completely automatically. Operator intervention is not required.
In vorteilhafter Weise ist die Vorrichtung so ausgestaltet, wie in Anspruch 2 unter Schutz gestellt. Durch die einzelnen Schaltabschnitte der Stromschiene können die Saugwagen so gesteuert, d.h. angehalten oder bewegt werden, wie es erforderlich ist, um die Verbindung der Saughaube mit dem entsprechenden Auspuff herzustellen und nach Bewegung über den Bereich des Saugschlitzkanales diese Verbindung, die, wie gesagt, keine mechanische Kupplung aufweist, wieder zu trennen. Die einzelnen Schaltabschnitte der Stromschiene werden von einer zentralen Steuereinheit mit den entsprechenden Schaltimpulsen versorgt, d.h. wenn ein Elektromagnet für die Steuerung des Eingriffs mit den Mitnehmern sorgt, wird der entsprechende Abschnitt mit Strom versorgt, um die Verbindung herzustellen und stromlos geschaltet, um die Verbindung zu trennen. Vorzugsweise handelt es sich hier um eine Niederstromversorgung von beispielsweise 24 Volt.Advantageously, the device is configured as protected in
Um zu verhindern, daß ein Saugwagen auf den anderen auffährt, ist die Absaugvorrichtung vorteilhaftweise so gestaltet, wie in Anspruch 3 angegeben.In order to prevent one suction truck from colliding with the other, the suction device is advantageously designed in such a way that as stated in
In den Ansprüchen 4 und 5 sind besondere Einrichtungen im Bereich des Rücklaufs, nämlich eine Pufferzone und eine Schleuse, unter Schutz gestellt. Die Pufferzone, die an ihrem in Förderrichtung liegenden Ende eine Startposition aufweist, sorgt dafür, daß immer eine genügende Anzahl von Saugwagen bereitstehen. Die Schleuse ermöglicht ein Ein- und Ausschleusen zu Reparatur- oder Wartungszwecken.In
In den sensiblen Bereichen sind die Schaltabschnitte entsprechend kurz, um hier die notwendigen Steuervorgänge auszulösen (Anspruch 6). Die Absaugvorrichtung ist in vorteilhafter Weise so ausgebildet, wie in Anspruch 7 vorgesehen, um die Saugwagen zur Verbindung mit dem Kraftfahrzeug an dieses bzw. an den Auspuff heranzufahren und nach erfolgter Absaugung wieder für eine Trennung zu sorgen.In the sensitive areas, the switching sections are correspondingly short in order to trigger the necessary control processes here (claim 6). The suction device is advantageously designed as provided in claim 7 in order to drive the suction vehicle for connection to the motor vehicle to this or to the exhaust and to ensure a separation again after the suction has taken place.
Die Anordnung erfolgt in vorteilhafter Weise so wie in Anspruch 18 angegeben.The arrangement is advantageously as specified in claim 18.
Um eine sichere Trennung zu ermöglichen, ist eine Stoppstrecke vor dem Ausfahrabschnitt vorgesehen (Anspruch 9), um für eine sichere Trennung von Auspuff und Absaughaube zu sorgen.In order to enable a safe separation, a stop section is provided in front of the extension section (claim 9), in order to ensure a safe separation of the exhaust and exhaust hood.
Schließlich ist es noch möglich, für unvorhergesehene Störungsfälle eine Sicherheitskupplung (Anspruch 10) zwischen Saughaube und Saugwagen vorzusehen, die eine mechanische Trennung dieser Teile ermöglicht.Finally, it is still possible to provide a safety coupling (claim 10) between the suction hood and suction truck for unforeseen malfunctions, which enables a mechanical separation of these parts.
Im folgenden wird die Erfindung unter Hinweis auf die Zeichnung anhand eines Ausführungsbeispieles näher erläutert.The invention is explained in more detail below with reference to the drawing using an exemplary embodiment.

Die in der Zeichnung dargestellte Absaugvorrichtung dient der Absaugung von Auspuffgasen von Kraftfahrzeugen, die bei Bewegung durch ihren Förderer 1 über eine Teststrecke einen Probelauf durchführen. Zu diesem Zweck müssen die Absaugwagen bei Bewegung über diese Teststrecke mit dem Auspuff des entsprechenden Kraftfahrzeuges so "verbunden" werden, daß eine sichere Absaugung erfolgt.The suction device shown in the drawing is used to extract exhaust gases from motor vehicles which carry out a test run when moved by their conveyor 1 over a test track. For this purpose, the suction trolleys must be "connected" to the exhaust of the corresponding motor vehicle when moving over this test section in such a way that a safe extraction takes place.
Die Kraftfahrzeuge, von denen eines in Fig. 2 schematisch dargestellt ist, werden durch einen ersten Förderer 1, in diesem Falle einen Hängeförderer, über ein Podest 2 bewegt. Das Podest 2 weist in diesem Bereich einen Schlitz auf, unter dem ein Saugschlitzkanal 4 angeordnet ist, der zwischen Schienen 3 liegt, die, wie in Fig. 2 ersichtlich, ein endloses, d.h. geschlossenes Oval bilden. Der Rücklauf der Schienen 3 ist mit 5 bezeichnet.The motor vehicles, one of which is shown schematically in FIG. 2, are moved over a
Der Saugschlitzkanal 4 mit seinen Schienen 3 liegt auf einem höheren Niveau als der Rücklauf. Auf diese höhergelegene Niveauebene führt ein Einfahrabschnitt 6 und von dieser Ebene wieder hinunter ein Ausfahrabschnitt 7.The
Parallel zu der Schiene 3 für die Saugwagen 20 ist eine Stromschiene 8 vorgesehen (siehe Fig. 3). Diese Stromschiene liegt aus. Innerhalb der Schiene 3 und ihres Rücklaufabschnittes 5 liegt eine zweiter Förderer 9, der als Kettenförderer (Kreuzgelenkkette) ausgebildet ist. Dieser zweite, von dem ersten unabhängige Förderer, wird synchron mit dem ersten Förderer 1 angetrieben, um die Bewegung der Saugwagen mit denjenigen der Kraftfahrzeuge zu synchronisieren. An dem zweiten Förderer 9 sind Mitnehmer 10 für die einzelnen Saugwagen 20 vorgesehen.A
Die Saugwagen 20 bestehen aus einem Gestell 25, an dem die Laufrollen 24 gelagert sind. Diese Laufrollen 24 laufen auf den Schienen 3, wie es insbesondere der Fig. 1 zu entnehmen ist. Jeder Saugwagen weist eine Saugdüse 22 auf, die mit einer Saughaube 21 verbunden ist, die durch einen Schlitz in dem Podest 2 über dieses hinaus und auf die Ebene des Auspuffes des Kraftfahrzeuges ragt. Die Saugdüse 22 tritt durch eine elastische Lippendichtung 23 des ortsfesten Saugschlitzkanales 4 hindurch und öffnet diese und stellt so die Verbindung mit dem Unterdruck innerhalb des Saugschlitzkanales 4 her.The
Der Saugschlitzkanal 4 liegt in dem Testbereich der Schiene 3 zwischen dieser (Fig. 3) und auf einem höheren Niveau (Fig. 2).The
An dem Gestell 25 befindet sich ein Elektromagnet 29 in einem Gehäuse 28. Dieser Elektromagnet betätigt eine Klinke 30, wobei die beiden Stellungen dieser Klinke 13 der Fig. 1 zu entnehmen sind. Der Elektromagnet ist über elektrische Leitungen 27 mit Kontakten 26 verbunden, die in die Stromschiene 8 eingreifen. Es ist leicht erkennbar, daß die Klinker 30, je nachdem, ob der Elektromagnet 29 mit Strom versorgt oder stromlos ist, eine Stellung einnimmt, in der ein Eingriff mit einem Mitnehmer 10 hergestellt ist, und eine andere Stellung einnimmt, in der die Verbindung zu dem zweiten Förderer 9 unterbrochen ist.An
Die Stromschiene ist in einzelne elektrisch voneinander getrennte und unabhängig voneinander ein- und ausschaltbare Schaltabschnitte unterteilt. Einige von diesen sind in Fig. 3 dargestellt und mit 14 bis 19 bezeichnet.The busbar is divided into individual, electrically separate switching sections that can be switched on and off independently of one another. Some of these are shown in Fig. 3 and designated 14 to 19.
Die Schaltabschnitte 14 bis 16 bilden eine Pufferzone, in der die Bereitstellung der Saugwagen vor dem Einkuppeln erfolgt. Der letzte Schaltabschnitt 14 in Förderrichtung ist der Startabschnitt. Hier wird der entsprechende Saugwagen 20 genau zu dem Zeitpunkt gestartet, der sicherstellt, daß er sich beim Hochfahren auf dem Einfahrabschnitt 6 mit dem zugeordneten Auspuff verbindet.The
Eine spezielle Kombination und Anordnung von Sensoren und Schaltern ermöglicht eine Fahrzeuglängenabfrage und liefert das Startsignal für den am Start stehenden Saugwagen. Somit ist es möglich, für jedes beliebige Fahrzeug einen Saugwagen im richtigen Moment zu starten.A special combination and arrangement of sensors and switches enables the vehicle length to be queried and provides the start signal for the vacuum truck at the start. It is therefore possible to start a vacuum truck for any vehicle at the right moment.
Wie beim Betrachten der Fig. 4 deutlich wird, ist an jedem Saugwagen 20 eine Fotozelle (Reflektions-Lichttaster) 31 vorgesehen, die bei Annäherung an einen vorausfahrenden oder stehenden Saugwagen dafür sorgt, daß die Klinke ihres Saugwagens von dem Mitnehmer getrennt und damit die Bewegung unterbrochen wird. Dieses geschieht vorzugsweise in der Pufferzone.As is clear when looking at FIG. 4, a photocell (reflection light sensor) 31 is provided on each
In Förderrichtung vor der Pufferzone ist eine Schleuse 13 vorgesehen, die einen Abschnitt der Schienen 3 im Rücklauf 5 aufweist, der seitlich herausbewegbar ist, um das Ein- oder Ausschleusen von Saugwagen auf eine Reparaturschiene 12 oder eine Rangierschiene 11 vorzunehmen. Im Bereich der Schleuse sind ebenfalls kurze Schaltabschnitte 18, 19 für die Stromschiene 8 vorgesehen, um die entsprechenden Steuerimpulse durchzuführen. Die Schleuse wird vorzugsweise pneumatisch bewegt. Ein Ausschleusen von Saugwagen erfolgt beispielsweise zu Reparatur- oder Wartungszwecken.In the conveying direction in front of the buffer zone, a lock 13 is provided which has a section of the
Eine spezielle Sensorik überprüft das Saugwagenoberteil auf korrekten Sitz auf dem Saugenwagenunterteil. Ist die Position Oberteil zu Unterteil zueinander verschoben, wird dies erkannt und der defekte Saugwagen wird automatisch ausgeschleust.A special sensor system checks the upper part of the suction vehicle for correct seating on the lower part of the suction vehicle. If the position of the upper part to the lower part is shifted towards each other, this is recognized and the defective vacuum truck is automatically removed.
Kurz vor dem Ausfahrabschnitt 7 ist eine Stoppstrecke mit einem entsprechenden Schaltabschnitt 17 in der Stromschiene 8 vorgesehen, um für ein kurzzeitiges Anhalten der Saugwagen und damit für ein sicheres Trennen von dem Auspuff vor der Bewegung auf das niedrigere Niveau im Rücklaufabschnitt zu sorgen.Shortly before the extension section 7, a stop section with a
Im Betrieb befindet sich ein Saugwagen in der Startposition im Schaltabschnitt 14. Wenn das Kraftfahrzeug an dem ersten Förderer 1 die entsprechende Position erreicht hat, wird der Elektromagnet 29 an diesem Saugwagen 20 mit Strom versorgt und der zweite Förderer bewegt den Saugwagen synchron zu dem Fahrzeug genau so, daß dieser nach dem Hochfahren auf dem Einfahrabschnitt 7 mit dem Auspuff verbunden wird, d.h. daß sich die Saughaube 21 über den Auspuff schiebt. Die in der Pufferzone bereitstehenden Saugwagen werden entsprechend in Förderrichtung bewegt, so daß der nächste Saugwagen in der Startposition bereitsteht.In operation, a vacuum truck is in the start position in the
Die Trennung erfolgt entsprechend, insbesondere durch ein "Stopp-Signal" für den Schaltabschnitt 17 der Stromschiene 8, und damit für eine kurzzeitige Unterbrechung der Bewegung des Saugwagens zum Trennen. Nach dem Trennen wird der Saugwagen auf dem Rücklauf 5 zurück in Richtung auf die Pufferzone bewegt. Ggf. kann er in der Schleuse 13 ausgeschleust werden, wenn dieses zu Reparatur- oder Wartungszwecken erforderlich ist.The separation takes place accordingly, in particular by means of a “stop signal” for the
Um unvorhergesehenen "Notfällen" vorzubeugen, ist die Saughaube durch eine mechanisch trennbare Sicherheitskupplung (Kugelschnäpper) mit dem zugehörigen Saugwagen verbunden, so daß eine mechanische Trennung dieser Teile, beispielsweise bei Auffahren auf ein Hindernis, erfolgt.In order to prevent unforeseen "emergencies", the suction hood is connected to the associated suction truck by a mechanically separable safety coupling (ball catch), so that these parts are mechanically separated, for example when hitting an obstacle.
