Definitions
- the invention relates to a device for conveying viscous material from a barrel-like, a container bottom and extending from the container bottom upwardly extending container shell container, with a follower plate for closing the container, which on the inside of the container interior facing the container surface adjacent to the container bottom and is movable away from the container bottom and having a material outlet opening and a ventilation opening, with a pump for conveying the viscous material through the material outlet opening and a ventilation device for introducing compressed air through the ventilation opening and with a lowering device for lowering the follower plate in the container, the at least one Double-acting cylinder with two pressure-tightly separated by a piston pressure chambers and a support plate carrying the follower plate, wherein the piston by means of a first en the pressure chambers extending, out of the cylinder axially led out piston rod is connected to the support means, that when lifting the follower plate in the direction away from the container bottom, the first pressure chamber is reduced.
- Such devices are used for example for applying adhesives or sealants in the production of motor vehicles.
- the viscous material is conveyed by the pump from the barrel-like container, wherein the follower plate is held by means of the lowering device always in contact with a surface of the material in the container.
- the follower plate is sealed, so on the one hand no material can escape from the container and on the other hand, no air from the environment can penetrate into the container. If the container is emptied, it is exchanged for a new, full container. For this purpose, the follower plate must be moved out of the container upwards.
- the interior of the container must be ventilated, since otherwise a vacuum is created in the container, which prevents the follower plate from moving out.
- air in particular compressed air
- the follower plate has a large area compared to the areas of the piston, introducing compressed air into the container is an effective means of urging the follower plate upwards. If the follower plate is moved upwards, the piston which is rigidly connected to it via the carrying device and the piston rod likewise moves upward, so that an overpressure is created in the first pressure chamber and a negative pressure is created in the second pressure chamber.
- the entrusted with the container change operator must therefore provide by discharging pressure medium from the first pressure chamber or introducing pressure medium into the second pressure chamber for pressure equalization. This requires some attention. It may happen that in the inattentiveness of the operator, the pressure medium in the first pressure chamber is compressed so much that upon escaping the follower plate from the container, when the pressure generated by the ventilation device escapes in the container, the pressure medium in the first pressure chamber acts as a prestressed spring and push the follower plate into or onto the container again with great force. This can damage the container or even injure the operator.
- the invention is based on the idea that it should not be left to the attention of the operator that the pressure in the first pressure chamber is reduced to a sufficient extent during a movement of the piston upwards, due to a lifting of the follower plate.
- a diverter valve is provided, which blocks a line leading from the first pressure chamber in a switching position and opens the line in another switching position for discharging pressure medium from the first pressure chamber.
- a control unit automatically switches the diverter valve before introducing compressed air through the vent or during initiation.
- the diverter valve is preferably a throttle valve or it is preceded by a throttle valve, so that the pressure medium from the first pressure chamber can not escape abruptly.
- the switching of the diverter valve can be done automatically before the introduction of compressed air into the container, for example, when the device is changed over by the operator from the pumping operation to a container exchange operation. In this case, a corresponding signal is automatically transmitted to the control unit, which then switches the drain valve.
- the introduction of the compressed air into the container by switching a valve in a compressed air supply line and that the switching of the valve in the compressed air supply line generates a signal to the control unit and this switches on receiving the signal diverting valve.
- the line can lead from the first pressure chamber via the discharge valve to an open end to the environment.
- the line leads from the first pressure chamber from the diverter valve into the second pressure chamber, so that both pressure chambers are short-circuited when the diverter valve is in its second switching position.
- a derivation of pressure medium from the first pressure chamber then causes a supply of pressure medium in the second pressure chamber. It then no additional measures must be taken to prevent the emergence of a negative pressure in the second pressure chamber.
- expedient is in the line between the discharge valve and the second pressure chamber arranged a check valve that releases a flow of the pressure medium in the second pressure chamber in a switching position and blocks a flow of the pressure medium from the second pressure chamber.
- the object underlying the invention is achieved by a device having the features of claim 10.
- a device having the features of claim 10.
- at least one pressure measuring element for detecting the pressure in the first and / or in the second pressure chamber and a control device for controlling the compressed air supply through the ventilation opening in dependence on the pressure in the first pressure chamber and / or in dependence on the pressure in the second pressure chamber.
- Each of the pressure measuring elements may in particular be a pressure sensor for measuring the pressure in the relevant pressure chamber.
- control device advantageously has a control valve that, depending on the pressure in the first pressure chamber and / or the pressure in the second pressure chamber for diverting pressure medium from the first pressure chamber and / or for supplying pressure medium into the second pressure chamber is switchable.
- the control device interrupts the introduction of compressed air when the pressure in the first pressure chamber rises above a first threshold and then releases the discharge of pressure medium from the first pressure chamber.
- the control device can interrupt the introduction of compressed air when the pressure in the second pressure chamber drops below a second threshold. In any case, the control device can further release the introduction of pressure medium in the second pressure chamber.
- the control device releases the introduction of compressed air into the container again, when the pressure in the first pressure chamber drops below a third threshold and then blocks the discharge of pressure medium from the first pressure chamber.
- the control device can release the introduction of compressed air again when the Pressure in the second pressure chamber rises above a fourth threshold value and the control device can then block the introduction of pressure medium into the second pressure chamber.
- FIG. 1 to 3 each a device for conveying viscous material in a schematic representation according to a first, a second and a third embodiment.
- a device 10, 110, 210 for conveying viscous material from a cylindrical container 12, which has a container bottom 14 and a container casing 16 which extends upwards from the container bottom 14, is shown schematically.
- the conveying device 10, 110, 210 (same features are provided in each embodiment with the same reference numerals) has a follower plate 18 which bears sealingly against an inner surface 20 of the container shell 16 resting on a surface 22 of the viscous material 26 received in the container interior 24 ,
- the follower plate 18 has a material outlet opening, not shown, to which a pump is connected, which promotes the viscous material, usually an adhesive or sealant, to an applicator.
- the amount of viscous material in the container 12 decreases, so that the follower plate 18 is gradually moved down to be held in abutment with the surface 22 of the viscous material 26.
- a lowering device 30 which has a support means 32 rigidly connected to the follower plate 18.
- it has two identical double-acting cylinder 34, which are arranged on both sides of the follower plate 18, so that their central axes are in line with the central axis of the follower plate 18.
- the cylinders 34 each have a piston 36, which has a first, upper pressure chamber 38 and a second, lower pressure chamber 40 pressure-tight against each other demarcated.
- a piston rod 42 which is guided out axially sealed from the cylinder 34, wherein both piston rods 42 are rigidly connected to the support means 32 extends.
- the follower plate 18 By introducing pressure medium such as compressed air or hydraulic fluid into the pressure chambers 38, 40, the pistons 36 and with them the follower plate 18 can be moved up and down, in particular to follow the decreasing material level in the container 12.
- the first pressure chambers 38 communicate with each other as well as the second pressure chambers 40.
- the first pressure surface 38 respectively facing first effective surface 44 of the piston 36 is smaller than the second pressure chamber 40 facing the second effective surface 46.
- the two pressure chambers 38, 40 results in a resultant force upward, the approximately, with a Tolerance of less than 10%, preferably less than 5%, the weight of the follower plate 18, the support means 32, the piston rods 42 and the piston 36 compensates.
- the follower plate 18 has a ventilation opening 48, via which air and in particular compressed air can be introduced into the container interior 24.
- a ventilation device 50 is provided, which has a ventilation opening 48 extending to the compressed air line 52 which is connected to a compressed air system 54 and by means of a compressed air valve 56 can be shut off. If the container 12 is emptied, the follower plate 18 must be removed from it for a container exchange. Since this rests close to the inner surface 20, air must be introduced into the container interior via the ventilation opening 48, since otherwise raising the follower plate by means of the lowering device 30 would lead to a lifting of the container 12.
- a discharge valve 58 is provided in a line 60 leading to the first pressure chambers 38, which blocks the line 60 in a first switching position and opens in a second switching position to the environment, as in FIG Fig. 1 shown.
- the discharge valve 58 is brought into the second switching position, so that pressure medium from the first pressure chambers 38 can escape into the environment when the follower plate 18 is moved upward.
- the switching of the diverter valve 58 in the second switching position can for example be done manually, with a control or regulating device blocking the venting of the container interior 24, as long as the diverter valve 58 is in its first switching position.
- the switching of the diverter valve 58 in the second switching position can also be done automatically by a control unit when the conveyor 10 is switched from a delivery mode in which it is ready to convey material 26 from the container 12 in a container change mode in which the Material promotion is prevented and an upward movement of the follower plate 18 is released.
- a control unit when the conveyor 10 is switched from a delivery mode in which it is ready to convey material 26 from the container 12 in a container change mode in which the Material promotion is prevented and an upward movement of the follower plate 18 is released.
- the line 60 in which the diverter valve 58 is disposed between the two pressure chambers 38, 40.
- the diverter valve 58 is brought into its second switching position, as described in connection with the first embodiment, so that a bypass between the pressure chambers 38, 40 is made. If the follower plate 18 is moved upward, pressure medium from the first pressure chambers 38 is displaced into the second pressure chambers 40.
- a check valve 64 is disposed between the diverter valve 58 and each of the second pressure chambers 40.
- a first pressure sensor 70 for measuring the pressure in the first pressure chambers 38 and a second pressure sensor 72 for measuring the pressure in the second pressure chambers 40 provided, the measured values are transmitted to a control device not shown.
- compressed air is introduced into the container 12 by means of the aeration device. With the resulting movement of the follower plate 18 and the piston 36 upward, the pressure in the first pressure chamber 38 increases, while the pressure in the second pressure chamber 40 decreases.
- the control device suppresses the compressed air supply into the container interior 24 and switches a control valve 74 into its in Fig. 3 shown switching position, derived in the pressure medium from the first pressure chamber 38 and pressure medium is introduced into the second pressure chamber 40. If the pressure measured by the first pressure sensor 70 falls below a predetermined third threshold value or if the pressure measured by the second pressure sensor 72 rises above a predetermined fourth threshold value, then the control device switches the control valve 74 back into and out of pressure medium into and out of it the pressure chambers blocking position and releases the compressed air supply into the container interior 24 again. This process is repeated until the follower plate 18 is removed from the container 12.
- Reference numerals 70, 72 in FIG Fig. 3 may also refer to pressure switches which, without the need for a separate control device, will switch the control valve 74 as described when these threshold values are reached.
- the pressure switches 70, 72 thus combine the functions of a pressure measuring element and a control device with each other.
- the invention relates to a device 10, 110, 210 for conveying viscous material 26 from a barrel-like, a container bottom 14 and extending from the container bottom 14 upwardly extending container shell 16 container 12, with a follower plate 18 for closing the Container 12, which at the container interior 24 facing inner surface 20 of the container shell 16th adjacent to the container bottom 14 and away from the container bottom 14 and having a material outlet opening and a vent opening 48, with a pump for conveying the viscous material 26 through the material outlet opening and a ventilation device 50 for introducing compressed air through the ventilation opening 48 and with a Lowering device 30 for lowering the follower plate 18 in the container 12, the at least one double-acting cylinder 34 with two pressure-tight by a piston 36 delimited pressure chambers 38, 40 and a follower plate 18 carrying support means 32, wherein the piston 36 by means of a first by a Pressure chambers 38 extending, out of the cylinder 34 axially led out piston rod 42 is connected to the support means 32, that

Es ist daher Aufgabe der Erfindung, eine Vorrichtung der eingangs genannten Art derart weiterzubilden, dass sie sicherer zu handhaben ist.It is therefore an object of the invention to develop a device of the type mentioned in such a way that it is safer to handle.
Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung mit den Merkmalen des Anspruchs 1, alternativ durch eine Vorrichtung mit den Merkmalen des Anspruchs 10 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.This object is achieved by a device having the features of claim 1, alternatively by a device having the features of
Der Erfindung liegt der Gedanke zugrunde, es nicht der Aufmerksamkeit der Bedienperson zu überlassen, dass der Druck im ersten Druckraum bei einer Bewegung des Kolbens nach oben, bedingt durch ein Anheben der Folgeplatte, in ausreichendem Maß reduziert wird. Zu diesem Zweck ist ein Ableitventil vorgesehen, welches in einer Schaltstellung eine aus dem ersten Druckraum führende Leitung sperrt und die Leitung in einer anderen Schaltstellung zum Ableiten von Druckmedium aus dem ersten Druckraum öffnet. Vorteilhaft schaltet eine Steuereinheit das Ableitventil automatisch vor dem Einleiten von Druckluft durch die Belüftungsöffnung oder während des Einleitens. Das Ableitventil ist dabei vorzugsweise ein Drosselventil oder ihm ist ein Drosselventil vorgeschaltet, so dass das Druckmedium aus dem ersten Druckraum nicht schlagartig entweichen kann.The invention is based on the idea that it should not be left to the attention of the operator that the pressure in the first pressure chamber is reduced to a sufficient extent during a movement of the piston upwards, due to a lifting of the follower plate. For this purpose, a diverter valve is provided, which blocks a line leading from the first pressure chamber in a switching position and opens the line in another switching position for discharging pressure medium from the first pressure chamber. Advantageously, a control unit automatically switches the diverter valve before introducing compressed air through the vent or during initiation. The diverter valve is preferably a throttle valve or it is preceded by a throttle valve, so that the pressure medium from the first pressure chamber can not escape abruptly.
Das Schalten des Ableitventils kann automatisch schon vor dem Einleiten von Druckluft in den Behälter erfolgen, beispielsweise dann, wenn die Vorrichtung von der Bedienperson vom Pumpbetrieb auf einen Behälterwechselbetrieb umgestellt wird. Dabei wird automatisch ein entsprechendes Signal an die Steuereinheit übermittelt, welche dann das Ableitventil schaltet. Es ist jedoch auch möglich, dass die Einleitung der Druckluft in den Behälter durch das Schalten eines Ventils in einer Druckluftzuleitung erfolgt und dass das Schalten des Ventils in der Druckluftzuleitung ein Signal an die Steuereinheit erzeugt und diese bei Empfang des Signals das Ableitventil schaltet. Die Leitung kann aus dem ersten Druckraum über das Ableitventil zu einem zur Umgebung offenen Ende führen.The switching of the diverter valve can be done automatically before the introduction of compressed air into the container, for example, when the device is changed over by the operator from the pumping operation to a container exchange operation. In this case, a corresponding signal is automatically transmitted to the control unit, which then switches the drain valve. However, it is also possible that the introduction of the compressed air into the container by switching a valve in a compressed air supply line and that the switching of the valve in the compressed air supply line generates a signal to the control unit and this switches on receiving the signal diverting valve. The line can lead from the first pressure chamber via the discharge valve to an open end to the environment.
Gemäß einer vorteilhaften Weiterbildung der Erfindung führt die Leitung aus dem ersten Druckraum vom Ableitventil in den zweiten Druckraum, sodass beide Druckräume bei in seiner zweiten Schaltstellung befindlichen Ableitventil kurzgeschlossen sind. Ein Ableiten von Druckmedium aus dem ersten Druckraum bedingt dann ein Zuleiten von Druckmedium in den zweiten Druckraum. Es müssen dann keine zusätzlichen Maßnahmen getroffen werden, um das Entstehen eines Unterdrucks im zweiten Druckraum zu verhindern. Zweckmäßig ist in der Leitung zwischen dem Ableitventil und dem zweiten Druckraum ein Rückschlagventil angeordnet, dass in einer Schaltstellung eine Strömung des Druckmediums in den zweiten Druckraum freigibt und eine Strömung des Druckmediums aus dem zweiten Druckraum sperrt.According to an advantageous development of the invention, the line leads from the first pressure chamber from the diverter valve into the second pressure chamber, so that both pressure chambers are short-circuited when the diverter valve is in its second switching position. A derivation of pressure medium from the first pressure chamber then causes a supply of pressure medium in the second pressure chamber. It then no additional measures must be taken to prevent the emergence of a negative pressure in the second pressure chamber. expedient is in the line between the discharge valve and the second pressure chamber arranged a check valve that releases a flow of the pressure medium in the second pressure chamber in a switching position and blocks a flow of the pressure medium from the second pressure chamber.
Alternativ wird die der Erfindung zu Grunde liegende Aufgabe durch eine Vorrichtung mit den Merkmalen des Anspruchs 10 gelöst. Gemäß Anspruch 10 ist mindestens ein Druckmesselement zur Detektion des Drucks im ersten und/oder im zweiten Druckraum und eine Regeleinrichtung zur Regelung der Druckluftzufuhr durch die Belüftungsöffnung in Abhängigkeit vom Druck im ersten Druckraum und/oder in Abhängigkeit vom Druck im zweiten Druckraum vorgesehen. Jedes der Druckmesselemente kann insbesondere ein Drucksensor zur Messung des Drucks im betreffenden Druckraum sein. Mittels der Regeleinrichtung kann der Druck im ersten und/oder im zweiten Druckraum durch Ableiten bzw. Einleiten von Druckmedium angepasst werden. Dabei weist die Regeleinrichtung vorteilhaft ein Regelventil auf, dass in Abhängigkeit vom Druck im ersten Druckraum und/oder vom Druck im zweiten Druckraum zum Ableiten von Druckmedium aus dem ersten Druckraum und/oder zum Zuleiten von Druckmedium in den zweiten Druckraum schaltbar ist. Insbesondere ist es möglich, dass die Regeleinrichtung die Einleitung von Druckluft unterbricht, wenn der Druck im ersten Druckraum über einen ersten Schwellwert steigt und dann die Ausleitung von Druckmedium aus dem ersten Druckraum freigibt. Alternativ oder ergänzend hierzu kann die Regeleinrichtung die Einleitung von Druckluft unterbrechen, wenn der Druck im zweiten Druckraum unter einen zweiten Schwellwert sinkt. In jedem Fall kann die Regeleinrichtung des weiteren die Einleitung von Druckmedium in den zweiten Druckraum freigeben.Alternatively, the object underlying the invention is achieved by a device having the features of
Gemäß einer vorteilhaften Weiterbildung gibt die Regeleinrichtung die Einleitung von Druckluft in den Behälter wieder frei, wenn der Druck im ersten Druckraum unter einen dritten Schwellwert sinkt und sperrt dann auch die Ausleitung von Druckmedium aus dem ersten Druckraum. Alternativ oder ergänzend hierzu kann die Regeleinrichtung die Einleitung von Druckluft wieder freigeben, wenn der Druck im zweiten Druckraum über einen vierten Schwellwert steigt und die Regeleinrichtung kann dann die Einleitung von Druckmedium in den zweiten Druckraum sperren.According to an advantageous development, the control device releases the introduction of compressed air into the container again, when the pressure in the first pressure chamber drops below a third threshold and then blocks the discharge of pressure medium from the first pressure chamber. Alternatively or additionally, the control device can release the introduction of compressed air again when the Pressure in the second pressure chamber rises above a fourth threshold value and the control device can then block the introduction of pressure medium into the second pressure chamber.
Im folgenden wird die Erfindung anhand dreier schematisch dargestellter Ausführungsbeispiele näher erläutert. Es zeigen
In
Zu diesem Zweck ist eine Absenkeinrichtung 30 vorgesehen, die eine starr mit der Folgeplatte 18 verbundene Trageinrichtung 32 aufweist. Zudem weist sie zwei baugleiche doppeltwirkende Zylinder 34 auf, die beidseitig der Folgeplatte 18 angeordnet sind, so dass ihre Mittelachsen auf einer Linie mit der Mittelachse der Folgeplatte 18 liegen. Die Zylinder 34 weisen jeweils einen Kolben 36 auf, der einen ersten, oberen Druckraum 38 und einen zweiten, unteren Druckraum 40 druckdicht gegeneinander abgrenzt. Durch den ersten Druckraum 38 verläuft jeweils eine Kolbenstange 42, welche axial aus dem Zylinder 34 abgedichtet herausgeführt ist, wobei beide Kolbenstangen 42 starr mit der Trageinrichtung 32 verbunden sind. Durch Einleiten von Druckmedium wie Druckluft oder Hydraulikflüssigkeit in die Druckräume 38, 40 lassen sich die Kolben 36 und mit ihnen die Folgeplatte 18 nach oben und unten bewegen, insbesondere um dem abnehmenden Materialspiegel im Behälter 12 zu folgen. Die ersten Druckräume 38 kommunizieren ebenso miteinander wie die zweiten Druckräume 40.For this purpose, a lowering
Die dem ersten Druckraum 38 jeweils zugewandte erste wirksame Fläche 44 des Kolbens 36 ist kleiner als die dem zweiten Druckraum 40 zugewandte zweite wirksame Fläche 46. Bei gleichem Druck in beiden Druckräumen 38, 40 ergibt sich eine resultierende Kraft nach oben, die ungefähr, mit einer Toleranz von weniger als 10%, vorzugsweise von weniger als 5%, das Gewicht der Folgeplatte 18, der Trageinrichtung 32, der Kolbenstangen 42 und der Kolben 36 ausgleicht.The
Die Folgeplatte 18 weist eine Belüftungsöffnung 48 auf, über die Luft und insbesondere Druckluft in das Behälterinnere 24 eingeleitet werden kann. Zu diesem Zweck ist eine Belüftungseinrichtung 50 vorgesehen, die eine zur Belüftungsöffnung 48 verlaufende Druckluftleitung 52 aufweist, die an ein Druckluftsystem 54 angeschlossen ist und mittels eines Druckluftventils 56 absperrbar ist. Ist der Behälter 12 entleert, so muss für einen Behältertausch die Folgeplatte 18 aus ihm entfernt werden. Da diese dicht an der Innenfläche 20 anliegt, muss über die Belüftungsöffnung 48 Luft in das Behälterinnere eingeleitet werden, da sonst ein Anheben der Folgeplatte mittels der Absenkeinrichtung 30 zu einem Anheben des Behälters 12 führen würde. Das Einleiten von Druckluft in das Behälterinnere 24 wird zudem dazu genutzt, die Folgeplatte 18 anzuheben, da deren dem Behälterinneren 24 zugewandte Fläche groß ist im Vergleich zu den wirksamen Flächen 44, 46 der Kolben 36 und somit bereits mit geringem Druck eine große Kraft erzielbar ist. Um eine Kompression des Druckmediums im ersten Druckraum 38 zu vermeiden, sind gemäß den drei Ausführungsbeispielen die im folgenden beschriebenen Maßnahmen vorgesehen.The
