Description

The invention relates to a valve arrangement, with a one-piece strip-shaped valve carrier body on which several Valve units in the longitudinal direction of the valve carrier body are mounted side by side, each with a valve and at least one electrically operated valve drive have, the valves with in the valve support body extending fluid channels are connected and the valve actuators above them assigned plug contact means with regard electrical connection means fixed to the valve carrier body are electrically contacted, with further for the transmission of control signals serving electrical Connect ladders.

Valve arrangements of this type are, for example, in the prospectus "Valve and installation islands" No. 119, page 8/9 from Festo KG. They contain a one-piece there strip-shaped valve carrier body, which can be detached with valve units arranged side by side which is a valve and at least one, for example valve actuator designed as an electromagnet contain. There is a housing along the valve body mounted, one parallel to the valve body extending circuit board accommodates the electrical connection means is equipped. The valve actuators of the individual Valve units are each equipped with plug contact means, the assembly of the valves with the electrical Connection means are contacted so that under mediation the circuit board an electrical connection to an electronic Control device can be manufactured.

The known valve arrangement works extremely reliably and enables a quite rational production and Assembly. However, this sets complex and therefore expensive manufacturing machines ahead, which negatively affects pricing precipitates. Hence the task of the present Invention, a valve assembly of the aforementioned To create a type that has a less expensive structure.

To solve this problem it is provided that each valve its own, the associated electrical connection means Connection module is assigned, the connection modules all valves without mutual electrical connection in the longitudinal direction of the valve carrier body successively lined up and individually on the valve body are fixed, and being the continuing electrical conductor are designed as flexible wire conductors.

In this way, the valve actuators are assigned electrical connection means no longer part of a Taking into account the number of valve units in their Dimensions of pre-assembled circuit board, but are provided on connection modules that the individual valves are individually assigned. One can therefore in manufacturing and assembly of the valve assembly the necessary electrical Follow-up measures simply by using a realize corresponding number of connection modules, whereby one is very variable, since the connection modules with each other no connections for the transmission of control signals exhibit. To valve assemblies with different numbers of valve units can be realized on the part of the valve carrier body fall back on yard goods that cut to length as required, the valve carrier body obtained then with the desired number of connection modules equips. Since the necessary manufacturing and assembly operations are relatively simple and not necessarily the use of complex, sophisticated manufacturing and assembly machines may require the valve assembly are produced relatively inexpensively overall. There the valve units are expediently independent of the connection modules are fixed to the valve body, they can very easy to assemble or disassemble, the assembly or disassembly the simultaneous manufacture or separation the electrical plug connection between the plug contact means and the connection modules has the consequence, since this on Valve carrier bodies remain.

DE 42 22 637 C2 already has a valve arrangement in which the valve actuators for electrical actuation are contacted with individual circuit boards. This However, circuit boards are used to form a signal distributor coupled with each other and also in terms of signal technology electrically chained, which has the consequence that the Do not select any number of valve actuators to be controlled lets, but given by the design of the circuit boards is. In addition, the valve carrier body in individual Segments is divided, which is a high degree of flexibility guaranteed when realizing different lengths, but at the same time a relatively high installation effort has the consequence.

Advantageous developments of the invention emerge from the subclaims forth.

In a particularly advantageous embodiment, each Connection module via an existing plastic material Base body, for example, by injection molding can be produced inexpensively and as a carrier for the connection means serves. The connection means individually firmly integrated or preferably as components one releasably fixed to the respective base body Be formed connector, which is alternatively can be used as a simple valve plug. So you can use components when realizing the valve arrangement, which can alternatively be used for other purposes can, in this respect, by using identical parts another To bring about cost savings.

All connection modules are expediently as individual Individual components executed, which one of the desired Number installed accordingly. Alternatively, it would be also possible to base the body as slightly apart to carry out separable components of a basic body strand, thus, for example, a string-like arrangement in a row and base bodies connected to one another by predetermined separation points, which one then only needs has to separate.

If the valve units of the valve arrangement are at a corresponding Use case individually controlled electrically should be recommended, a design in which the acting as a further electrical conductor flexible Wire conductors individually from the individual connection modules and are led away from the valve assembly. At a The flexible wire conductors are an alternative to this Board the valve arrangement to a central interface device led from where a central electrical Connection to an external electronic control device is possible, for example through a fieldbus connection or a multipole connection. The central interface device can also do it yourself with an electronic control unit be equipped.

In order to fix the connection modules on the valve carrier body, the latter be equipped with a holding rail, on or in which the connection modules are lined up. The holding rail is preferably an integral part of the valve carrier body, so that when cutting the valve carrier body on the desired length dimension automatically also the correct length dimension for the holding rail.

One or more anchoring grooves can be attached to the holding rail be provided, in which the connection modules engage. Furthermore, the holding rail can extend in the longitudinal direction of the valve support body extending recess, in that the connection modules are at least partially used, so that there is a secure fixation in connection with a Protection against damage results and at the same time compact Dimensions of the overall arrangement are possible.

With a substantially rectangular cross-section Valve carrier body can have the recess in the corner area be provided as a corner recess. Used Connection modules are therefore still easily accessible. Moreover the flexible wire conductors can be very convenient from each individual Connection module without obstruction by the valve body be dissipated.

In a further embodiment, the recess is groove-like trained, the orientation expediently so is taken that the longitudinal groove opening in the same Is oriented in the same way as the assembly surface of the valve carrier body, on which the valve units with their valves sit. The slot opening thus faces the valve actuators, what the automatic manufacturing and interrupting the electrical plug connection between the valve drives and the connection modules during assembly and disassembly of the valve units favored.

The flexible wire conductors can be in the recess if necessary be laid, being covered by the connection modules are. This design is particularly recommended if a central interface device on the support rail is arranged. Then, invisible from the outside, flexible electrical connections between the connection modules and the central interface device become.

Through end pieces inserted into the recess of the holding rail, that flank the row of connection modules on the axial side, the connection modules can be fixed particularly simply in this way be that their longitudinal position with respect to the valve carrier body is set.

Preferably, the connection modules can be on the valve carrier body in this way be mounted so that they are from one end of the Valve carrier body forth in at least one in the longitudinal direction extending anchoring groove and / or a corresponding one Recess having a course can be inserted.

The valve carrier body could be designed as an injection molded body and consist of plastic material. An alternative The valve carrier body is made of aluminum material and is designed as an extrusion, in which over the extending the entire length of the valve support body Fastening measures for the connection modules are particularly simple let it be realized.

The generally designated in the drawing with reference number 1 Valve arrangements each have an elongated one Valve carrier 2 with a plate-like flat design strip-shaped valve support body 3, which is the overall length of the Valve arrangements 1 specifies. The valve carrier body 3 is a one-piece component and can in particular be made of aluminum material existing extrusion. Compared to a plastic construction, for example, using injection molding technology extrusion has the advantage, very much provide a wide variety of lengths to be able to. In particular, it is possible for the valve carrier body to manufacture on the basis of the goods of the desired The length of the valve carrier body is cut to length accordingly becomes. Without the laborious assembly of individual components can be very different Lengths are generated.

The valve support body 3 contains one in its longitudinal direction 4 extending support rail 5 and one alongside next to this arranged placement section 6 with the same Longitudinal orientation. Holding rail 5 and assembly section 6 are connected in one piece and thus more integral Part of the valve carrier body 3.

On a longitudinal side referred to below as the component side of the valve carrier body 3 are a plurality of valve units 8 mounted so that they are in the longitudinal direction 4 of the valve carrier body 3 lie next to each other. So there is a line up of valve units 8 in front of which by double arrow indicated alignment 9 parallel to the longitudinal axis 4 of the valve support body 3 extends.

Each valve unit 8 is a unit consisting of one Valve 12 and at least one for activating valve 12 Serving, electrically operated valve drive 13. The types the valves 12 are arbitrary per se, it being in the embodiment is 2/2-way valves, each are equipped with a single valve drive 13.

Electromagnets or come, for example, as valve drives preferably piezo actuators for use. They can Actuate valve 12 directly, depending on the type, or to a Acting pilot valve of valve 12 acting pilot valve.

The valve units 8 with their valves 12 are interposed Seals not shown on the component side to an assembly surface 7 of the valve carrier body 3 scheduled. There are fastening screws for detachable fastening 14 provided that the valve housing of each Push valve 12 through and into the threaded holes of the Assembly section 6 are screwed. Other fastening measures would also be conceivable, for example locks and / or latches.

Each assembled valve 12 communicates with the inside of the valve support body 3 running fluid channels 16. This acts it is a feed channel in the embodiment 16a, a ventilation channel 16b and a working channel 16c. Corresponding to that caused by the valve drive 13 Switch position of a respective valve 12, this is at Embodiment capable of the individually assigned Working channel 16c optionally with the feed channel 16a or Vent channel 16b to connect, the other Channel is separated. A connected to the working channel 16c Consumers, for example a fluid-operated drive, can in this way with print medium, in particular Compressed air, fed or vented.

All valves 12 are fed and vented centrally. For this purpose the assembly section 6 is from the feed channel 16a and from the ventilation duct 16b in the longitudinal direction 4 interspersed, with these channels in the interior of the placement section 6 branch channels branch off, which over the first channel mouths 17 to the individual areas equipped with valves 12 the placement area 7 open out. Feeding and The compressed air is discharged centrally via a Face of the valve carrier body 3.

Additional, provided on the individual assembly areas, second channel openings 18 each communicate with one working channel 16c, which in particular to a long side of the valve carrier body 3 is performed and there the connection to allows a consumer leading fluid line.

Through the valves 12, the first and second channel openings 17, 18 of a respective assembly area are interconnected in terms of circuitry that set the conditions explained above.

The valve drives 13 are in this way laterally to the associated one Valve 12 is set so that it is transverse to the alignment 9 in the area of the holding rail 5 in particular protrude above this. The valve actuators 13 provided plug contact means 19 with on the valve carrier body 3 fixed electrical connection means 22 in electrical Connection. The term "plug-in contact means" should also be pure Touch contact means are detected.

The electrical contacted with a respective valve drive 13 Connection means 22 are each part of the same an independent connection module 23, so that per valve unit 8 such a connection module 23 is present, the has the relevant electrical connection means 22. Of each of these connection means 23 lead as flexible wire conductors 24 trained, used for the transmission of control signals electrical conductors away, on the one hand with the electrical Connection means 22 of the relevant connection module 23 are connected and on the other hand with any electrical Facility are connectable, the use case specific is trained.

In the embodiment of Figures 4 and 5 are the flexible Wire conductor 24 from the individual connection modules 23 each individually guided away, while also being carried away by lead the valve assembly 1 away, for example towards one external electronic control device that receives the control signals for actuating the valve drives 13 as required supplies. In contrast, the flexible wire conductors run 24 in the embodiment of Figures 1 to 3 on board of the valve arrangement 1 to be designed as part of the same central interface device 25 from where a central link with an external institution is possible. Here, too, the external facility can be operated by a be formed electronic control device, the electrical Control signals for controlling or actuating the valve drives 13 supplies.

The central interface device 25 has in the exemplary embodiment via a multipole plug device 26 for Connection of a continuing central cable. Alternative would be a fieldbus connection device is also possible, in which The central interface device 25 expediently is equipped with a suitable fieldbus unit, which assign the incoming control signals to the individual connection modules 23 and the associated valve drives 13 forwards.

It is also easily possible to use the central interface device 25 even with one to control the valve actuators 13 serving electronic control unit, especially with a programmable logic controller Control that is customized according to the application lets program.

The individual connection modules 23 are in the longitudinal direction 4 of the valve carrier body 3 on or in the holding rail 5 successively lined up, immediately adjacent to each other concern, but no mutual control technology have electrical connection, i.e. not with each other in terms of control technology are chained. The ones that control valve actuation electrical control signals are individually via the supplied flexible wire 24, also a required Neutral conductor and / or the required electrical energy supply individually via these flexible wire conductors can be done. For the purposes of a common neutral and / or a common energy supply, however if necessary also direct electrical connections between the Connection modules 23 may be provided, preferably also using flexible wire conductors.

The connection modules 23 are individually on the valve carrier body 3 fixed so that they are not necessarily also among themselves must be mechanically connected, albeit this it is possible. The preferred essentially plate or block-like connection modules 23 - in the embodiment of Figures 4 and 5 they have a cube-like Shape - conveniently have a particular made of plastic material base body 27, the is equipped with the electrical connection centers 22. there the connection modules 23 are arranged in succession such that they are directly against each other with their base bodies 27 concern without being form-fitting in any way intervene.

The electrical connection means 22 can directly on the associated Base body 27 may be set. In the embodiment are assigned to a respective connection module 23 electrical connection means 22, however, as a component a connector 28 is formed, which in particular releasably is fixed to the associated base body 27, for example through a snap connection. This design has the advantage that the connector 28 is also independent of a base body 27 as a simple valve plug for contacting a Valve drive can be used and thus the possibility has valve assemblies of the type according to the invention and others Designs based on identical connector 28 to contact. This saves manufacturing costs.

In the embodiment, all connection modules 23 are as individual components made. However would be a design is also conceivable in which the base body is lightweight separable components of an initially still contiguous Base body strand are executed. It could a strand structure is present, which is by predetermined separation points interconnected base body includes, one Injection molding production can be based and the target separation points defined by areas of lesser material thickness are. The base bodies can then be removed from the base body strand separated in any number individually or contiguously and in single or coherent form on the valve carrier 2 can be installed.

To a valve assembly with a predetermined number of Obtaining valve units 8 can simply be a valve support body 3 corresponding length can be used with a appropriate number of connection modules 23 is populated. Since the latter are not in electrical contact with each other, is practically any number of connection modules 23 usable, which is a very flexible structure of valve arrangements allowed.

The exemplary embodiments have in common that the valve carrier body 3 in its section forming the holding rail 5 with one over the entire length of the valve carrier body 3 extending and extending in its longitudinal direction 4 Recess 29 is provided in which the connection modules 23rd sit in whole or in part. In the embodiment is the arrangement made so that the connection modules 23 completely are sunk in the recess 29, so that they fix securely with compact overall dimensions to let.

In all of the exemplary embodiments shown, the valve carrier body 3 essentially seen in cross section rectangular basic structure. This can, however, in certain Be provided with depressions or elevations, if the circumstances require it. Anyway the recess 29 in the exemplary embodiment in FIGS. 4 and 5 in a corner region of the valve support body 3, so that one could speak of a corner going recess. In contrast, the recess 29 is in the embodiment of Figures 1 to 3 groove-like, the extending over the entire length of the valve support body 3 pulling longitudinal opening 32 the same orientation has, as is the placement surface 7. In other words So the longitudinal opening 32 of the recess 29 the over they protrude valve actuators 13 facing what else also applies to the designs of Figures 4 and 5.

In both embodiments, the longitudinal opening 32 of the recess 29 placed so that it with the placement area 7 runs in one plane. differences between the two designs result from the fact that the recess 29 according to FIGS. 4 and 5 on the loading section 6 opposite long side is also open while a leg 33 of the holding rail there according to FIGS. 1 to 3 5 is located together with the assembly section 6 the two longitudinal boundaries of the groove-like recess 29 forms.

Since the recess 29 in the construction of Figures 4 and 5 the rear of the assembly section 6 opposite is open, can be very easily over this back the flexible wire conductors 24 from the valve assembly 1 lead away. These can be transverse to the longitudinal direction 4 from Go off valve carrier body 3.

In contrast to this, the design of FIGS. 1 to 3 offers itself to the flexible wire conductor 24 inside the recess 29 invisible from the outside and for example a flexible electrical conductor connection between the individual electrical connection means 22 and the central Make interface device 25. While at the 4 and 5 the cross section of the recess 29 is completely filled in by the respective connection module 23, here comes a design of the connection modules according to Figures 1 to 3 23 used, in which this only that of the long side Opening 32 associated with the upper region of the recess 29 document so that between them and that of the long side Opening 32 opposite base 34 of the recess 29 a free space remains in which the flexible Wire conductor 24 can be easily laid. The wire ladder 24 are covered by the connection modules that the Recess 29 practically in the region of the longitudinal opening 32 close like a lid.

The flexible wire conductor 24 can be a component in all cases of commercially available insulated wires or cables to prevent the emergence of Avoid short circuits.

Around the connection modules 23 in the associated recess 29 to fix securely individually, the holding rail 5 is in the area the recess 29 in the case of the embodiment according to figures 4 to 5 with one and in the case of the embodiment of the figures 1 to 3 equipped with two anchoring grooves 35. This extend over the entire length of the valve carrier body 3 in its longitudinal direction 4. Each connection module 23 with one of the anchoring groove 35 in question Anchoring section 36 equipped with which it in the concerned Anchoring groove 35 engages positively.

The anchoring groove 35 can be comparable to the embodiment of Figures 4 and 5 to an undercut Act longitudinal groove, for example a dovetail groove or a T-slot. According to Figures 4 and 5, a respective one Connection module 23 with its anchoring part 36 in the Anchoring groove 35 a that it is in the transverse direction of the anchoring groove 35 is firmly fixed and only on the End faces of the valve carrier body 3 associated end faces Groove openings 37 inserted into the anchoring groove 35 or can be taken from this. The connection modules 23 are thus in the frame of one of the end face of the valve support body 3 slide-in installation on the valve carrier body 3 set.

Comparable conditions are in the embodiment of Figures 1 to 3, but there are no undercuts there Anchoring grooves 35 are provided because the Connection modules 23 simultaneously in two anchoring grooves 35 intervention. These two anchoring grooves 35 are located on the one hand on the side surfaces delimiting the recess 29 of the leg 33 and on the other hand of the assembly section 6. They are preferably in the region of the longitudinal opening 32, where they face each other in the transverse direction of the recess 29 can. The base body 27 of the connection modules 23 are on opposite sides with protrusions formed and, for example, rib-like or rail-like Anchoring sections 36 equipped with which they in engage the two anchoring grooves 35, whereby they Installation here also from one end of the valve carrier body 3 forth in the front openings of the anchoring grooves 35 are inserted.

By anchoring the connection modules 23 thus achieved these are transverse to the longitudinal direction 4 of the valve carrier body 3 fixed immobile. By sliding along the anchoring grooves 35 or the recess 29, however, they can on the desired position in the area of the assigned valve drive 13 can be positioned. This can be done by appropriate dimensional adjustments achieved a certain stiffness be, which also ensures that the connection modules 23 the desired location axially immobile by friction being held. Once the plug connection between the pin-like plug contact means in the exemplary embodiment 19 and the complementary electrical connection means 22 manufactured, this also results in an automatic position fixation the connection modules 23.

In the embodiment of Figures 1 to 3 are in the recess 29 in addition at their two axial end regions End pieces 41 inserted and fixed, the series of connection modules 23 flank each end face and in position hold. Fasteners can also be attached through the pieces 41 42 be passed through, for fastening the end pieces 41 serve on the valve support body 3 and about the expedient also the entire valve carrier 2 on one holding structure can be specified.

To provide enough space for laying within the recess 29 having flexible wire conductor 24 available the recess 29 in the area of the base 34 via a have longitudinal extension 38, which is in the assembly section 6 stretched in and the feed channel 16a and / or practically infiltrate the ventilation duct 16b can. In this case, the end pieces 41 have expediently a corresponding cross-sectional shape.

The central interface device 25 can in the same Way as the connection modules 23 fixed to the support rail 5 his. As can be seen from Figures 2 and 3, the central Interface device 25 for this purpose via a housing 43, the underside with longitudinal anchoring parts 44 is equipped, their distance and cross-sectional shape the anchoring parts of the connection modules 23 corresponds. As a result, the housing 43 can be compared to the connection modules 23 while meshing the Anchoring sections 44 and the anchoring grooves 35 in the Recess 29 are inserted. The housing 43 comes here to lie above the valve support body 3, in Extension of the lined up valve units 8 the central interface device 25 expediently assigned to one of the axial end regions of the valve carrier 2.
