Description

The invention relates to a valve battery, with a plurality of particularly electrically actuated control valves, which are each connected via at least one individual supply channel to at least one common feed channel and at least one common vent channel to the connection of these channels, each with at least one connectable to a consumer individual working channel can be controlled, wherein an inserted into the at least one individual supply channel safety valve device is provided with at least one safety valve, which is selectively switchable between a release position and the supply of pressure medium to the associated control valve blocking position.

Valve batteries of this type have been known for a long time. For example, from the EP 1 041 325 B1 discloses a valve manifold, which discloses a plurality of each equipped with a control valve control modules, which are combined to form a module assembly. By means of a common supply channel passing through the module arrangement, all the control valves can be supplied with pressure medium at the same time. The venting of the control valves is done via one or two module assembly also passing common vent passage. The common supply channel is followed by a usable as a safety valve shut-off valve, which is able to shut off the common supply pressure from the pressure medium leading in feed channel when a fault occurs. The valve battery is then decoupled from the print media network. However, if the shut-off process is performed with the valve manifold still under full supply pressure, the pressure medium sealed off in the valve manifold can continue to be the cause of undesirable switching functions of the control valves. Furthermore, it is not possible to selectively remove individual control valves from the printing-media network.

The topic deals specifically with removing individual control valves from the print media network DE 10 2008 027 154 B4 , There is disclosed a distributor solenoid valve apparatus having a stop valve turned on in an individual supply passage departing from the central supply passage to the associated control valve. The supply channel, which is used to supply the associated control valve with compressed air, is thus looped through the control valve. The operation of the stop valve is effected by pulling and pressing, wherein the stop valve is switched by a pulling movement from the release position to the blocking position, whereas the reverse operation is effected by a pressure movement. To perform the pulling movement, the user must grasp an actuating knob protruding upward from the top of the stop valve and pull the valve lifter upwards. In particular, the gripping of the actuating knob and the subsequent pulling up of the valve stem requires an exact operation of the user, which is not easily and quickly perform. In the blocking position, the valve stem is relatively far from the top of the stop valve. There is a risk that the valve stem is bent in this position by the action of external forces, so that it is then no longer exactly movable back into the release position.

The object of the invention is to provide a valve battery of the type mentioned, in which a safety valve device can be operated quickly and reliable in a simple manner.

This object is achieved by a valve battery having the features of the independent claim 1. Further developments of the invention are shown in the subclaims.

The valve battery according to the invention is characterized in that the safety valve device has a pivoting device, via which the at least one safety valve can be switched by means of a pivoting operation between the release and the blocking position.

Such a pivoting operation of the at least one safety valve can be carried out quickly and reliably by the user in a simple manner.

In a further development of the invention, the safety valve device has a plurality of safety valves which are each assigned to one of the control valves.

It is possible that the safety valve arrangement has at least one uniformly manageable base module, on which a plurality of the safety valves are arranged, in particular integrated in the base module. In this case, the base module is a separate component from the rest of the valve battery, which can be mounted as needed to the rest of the valve battery, in particular to a fluid manifold. This makes it possible to retrofit conventional valve batteries with a safety valve device.

Furthermore, it is possible for the safety valve arrangement to have at least one, in particular a plurality of individually manageable individual modules, each with at least one safety valve. In this case, therefore, not more safety valves are integrated in a base module, but there are individual, for example, disk-shaped individual modules with a single safety valve before. Thereby it is possible to provide a certain one of the control valves of the valve battery with the safety valve device. It is of course possible to combine the individual modules with the base module. It is thus possible to use a single single module or alternatively a single base module. Furthermore, it is possible to use several individual modules at the same time or alternatively several base modules at the same time. Furthermore, it is possible to provide at least one individual module and at least one base module at the same time.

Advantageously, the first mounting surface are formed by an upper side of the fluid distributor and the second mounting surface by an underside of the fluid distributor. Thus, while the control valves are located on the first mounting surface, the at least one base module and / or the at least one individual module can be fastened to the underside of the fluid distributor. Conveniently, the first mounting surface is formed parallel to the second mounting surface.

In a particularly preferred manner, the pivoting device has at least one pivoting lever pivotable about a pivot axis by means of pivot bearing means, the pivoting movement of which can be transmitted to a valve member of an associated safety valve that can be positioned selectively in the release position or in the blocking position. The valve member may be, for example, a valve stem or a valve spool. Such a pivoting lever can be easily grasped by the user, so that he can perform the operation on the safety valve quickly and reliably, in which he imparts a pivoting movement to the pivot lever.

In a further development of the invention, the at least one pivoting lever is designed such that the pivoting movement triggered by its actuation can be transmitted by means of coupling means into a linear movement of the valve member.

In a further development of the invention, the at least one pivot lever on this side of the pivot axis arranged end freely ending first lever arm and arranged on the other side of the pivot axis second lever arm, which is connected via the coupling means pivotally connected to the valve member.

It is possible for the at least one pivoting lever to be disposed in front of a mounting surface oriented obliquely, in particular perpendicular to the second mounting surface, and the pivoting axis being aligned, in particular, parallel to the second mounting surface, on the mounting surface.

In a particularly preferred manner, the second lever arm of the pivot lever is laterally beyond the second mounting surface and is there coupled to the located below the second mounting surface valve member.

Conveniently, the first lever arm is longer than the second lever arm of the pivot lever. As a result, a lever translation is provided, which allows the user to cause actuation of the pivot lever by gripping the first lever arm by a relatively low force to be applied switching the valve member between the blocking and the release position.

In a further development of the invention, the pivot bearing means on a bearing receiver and a pivotally received in the bearing receptacle bearing journal. The pivot bearing means may thus have a pivot, which is expediently formed by bearing pin and bearing seat.

Particularly preferably, the bearing pin in the pivot lever and the bearing receptacle on the fluid distributor, in particular arranged on the mounting surface of the fluid distributor.

In a development of the invention, the bearing receptacle is designed as a bearing groove, while the bearing journal is part of a bearing web. Expediently, the bearing groove extends parallel along a longitudinal axis of the fluid distributor on the mounting surface. The bearing bar is expediently arranged on a rear side of the pivoting lever, in particular integrally formed there. Expediently, the bearing web comprises a base section extending over the width of the pivot lever and a bearing section of circular cross-section attached to the base section at the free end of the bearing web. Conveniently, the bearing bar is located at the rear in the region of the second lever arm of the pivot lever.

In a further development of the invention, the coupling means for coupling the pivot lever with the valve member on a formed on the second lever arm bearing eye, which is penetrated by a particular cylindrical bearing portion of the valve member. Alternatively, it would also be conceivable to form the bearing eye on the valve member and the bearing portion on the pivot lever, which then extends through the bearing eye on the valve member.

In a particularly preferred manner locking means are provided for releasably locking the pivot lever in the locking position. The locking means can be formed for example of components on the fluid distributor and components on the pivot lever. It is for example possible to provide a latching receptacle and a latching into the latching receptacle locking lug, wherein preferably the latching lug on the fluid distributor and the latching receptacle is formed on the pivot lever. Appropriately, engages on the pivot lever, in particular at the lower end of the second lever arm formed locking receptacle when pivoting into the blocking position, the lower side arranged on the fluid distributor locking lug and snaps there.

In a further development of the invention, the pivot lever has stop means which predetermine a defined position of the release position during this pivoting out of the blocking position. The stop means may, for example, have a stop web formed on the rear side of the pivoting lever, in particular in the region of the first lever arm.

Depending on the switching position of the valve spool is the passage between the first channel section 37 and the second and third channel sections 45 . 46 open or locked.

The safety valve device 29 has a pivoting device 47 on, over which the at least one safety valve 30 by means of a pivoting operation between the release and the blocking position 31 . 32 can be switched.

The swivel device 47 has at least one means of pivot bearing means about a pivot axis 48 swivel lever 49 on, whose pivotal movement to the optional in the release position 31 or in the locked position 32 positionable valve member 38 is transferable.

As in particular in 4 shown, has the pivot lever 49 a side of the pivot axis 48 arranged and freely ending first lever arm 50 and one beyond the pivot axis 48 arranged second lever arm 51 , The first lever arm 50 in the example is significantly longer than the second lever arm 51 educated. The swivel lever 49 has a convex curved front 52 and one parallel to the front 52 running back 53 on. The swivel lever 49 is one of the interface 26 opposite mounting surface 54 assigned. The pivot axis 48 of the pivot lever 49 lies in the area of this mounting surface 54 ,

As a pivot bearing means for pivotally mounting the pivot lever 49 is a camp recording 55 in the form of a parallel to the longitudinal axis 12 of the fluid distributor 13 extending Lagerernut provided. The bearing groove has a substantially circular cross-section with a narrowing slot, with which it attaches to the mounting surface 54 opens. The pivot bearing means also includes a journal 56 , which is pivotally mounted in the bearing receptacle or in the bearing groove. pivot 56 and Lagernut therefore form a hinge for the pivot lever 49 , The journal 56 is part of one of the back 53 of the pivot lever 49 in the area of the second lever arm 51 according to obliquely down aligned bearing bar 57 which extends substantially over the entire width of the pivoting lever 49 extends. The jetty 57 has a base section 58 , which expediently in one piece to the back 53 of the pivot lever 49 is attached and in particular integral with the Basisisabschnitt 58 connected trunnions 56 , which also extends in the direction of the longitudinal axis 12 has aligned longitudinal extent. The journal 56 is complementary to the configuration of the bearing groove provided with a circular cross-section, whereby it is inserted laterally into the bearing groove.

The coupling means for coupling the pivot lever 49 with the valve member 38 have one on the second lever arm 51 trained bearing eye 59 that of a cylindrical bearing section 60 on the operating section 41 of the valve member 38 is interspersed. The pivoting movement of the pivot lever 49 is thereby in a linear movement of the valve member 38 transfer.

The swivel device 47 also has locking means 61 for releasably locking the pivot lever 49 in the locked position 32 , The locking means 61 include one at the bottom edge of the fluid manifold 13 in the area of the mounting surface 54 trained elongated catch nose 62 and one in the region of the second lever arm 51 from the back 53 of the pivot lever 49 obliquely downwardly projecting locking receptacle 63 with a locking groove 64 , During the movement of the swivel lever 49 from the in 4 shown release position 31 in the in 5 shown blocking position 32 snaps the locking groove 64 into the catch 62 a, whereby the blocking position 32 secured in position.

The swivel lever 49 also has stop means 65 , which when pivoting out of the locked position 32 out a defined position of the release position 31 pretend. The lifting gear 65 include one from the back 53 in the area of the first lever arm 50 protruding stop bridge 66 who is in the release position 31 to the mounting surface 54 strikes and thus the release position 31 pretends.

To do that in 4 in the release position 31 located safety valve 30 in the locked position 32 To switch, the user attacks on the first lever arm 50 of the pivot lever 49 and pivots the pivot lever 49 around the pivot axis 48 with the first lever arm 50 away from the fluid distributor 13 , The second lever arm pivots 51 logically to the fluid distributor 13 out. The second lever arm presses 51 the operating section 51 the valve spool with the over the bearing eye 49 formed coupling as far inward until the stop 42 to the outer surface of the base module 34 strikes. The detent groove engages 64 on the pivot lever 49 into the catch 62 at the fluid distributor 13 one. By the displacement of the operating section 41 is the integrally coupled switching section 40 of the valve member 38 inevitably also displaced, the second ring section 43b the passage between the first channel section 37 and the second and third channel sections 45 . 46 locks. Via the feed channel 21 fed supply pressure can thus no longer via the individual currently shut off supply channel 33 to the associated control valve 15 reach. This makes it possible for the control valve 15 to change during operation without interrupting the fluid loading of the adjacent valves.

For the return movement of the pivot lever 49 , ie switching between the in 5 shown blocking position 32 in the in 4 shown release position 31 the user grips the first lever arm 50 of the pivot lever 49 and swings it back towards the fluid manifold 13 , wherein the locking groove 64 out of the catch 62 disengages. The pivoting movement is continued until the stop bar 66 to the mounting surface 54 abuts, causing the correct release position 31 is reached.

The 6 shows a second embodiment of the valve battery according to the invention 11 which differs from the first embodiment described above in that instead of a plurality of safety valves 30 receiving base module 34 a single module 67 is inserted, in which a single safety valve 30 is integrated.
