Description

box device

The invention relates to a can device for a compressed air line system, with a mounting side for mounting on a substrate and at least one compressed-air connection for connecting a compressed-air pipeline.

Such a can device with, for example, two or three compressed air connections and a flat mounting side for wall mounting is available in the form of final distribution boxes in the product range of Schneider Druckluft GmbH. The can device, e.g. a junction box, for example, screwed to a wall surface. Into the compressed air connections are e.g. Quick couplings can be screwed, to which in turn compressed air pipelines can be connected, preferably rigid, inflexible compressed air pipelines. If you want to expand the compressed air line system, the final distributor box is exchanged for another, for example, more compressed air connections exhibiting model. For this purpose, however, the compressed air line system must at least in the area of the can device to be replaced, e.g. the junction box, switched off or depressurized. Only then are the corresponding assembly work possible.

It is therefore the object of the present invention to provide a can device for a compressed air line system, which is easy to handle and allows easy expansion of the compressed air line system.

To solve the problem is provided in a can device of the type mentioned that it has a mounting side for mounting on the ground and at least one compressed air connection base socket and at least one on a base box daisy chain side of the base box by means of daisy chain fasteners releasably attachable additional box that the base box has at its base box daisy-chain side a base box header connection fluidly connected to the at least one compressed air connection for fluid communication with a supplemental outlet header connected to an additional box header side of the at least one supplementary box, and that the at least one supplementary box is a service unit and / or or a compressed air measuring device for generating measured data and / or at least one compressed air connection for a compressed air pipeline.

The concept according to the invention is therefore a modular concept, in which the base box can be mounted, for example, on a wall and forms a linking base for one or more additional modules in the form of an additional box. It is understood that additional cans in turn can be designed for further chaining, that is, for example, realized tower-like structures with the modular concept of the invention. Replacement and adaptation of additional cans is easily possible. Only the base module or the base box remains mounted on the ground and connected to the other components of the compressed air line system, for example, one or more compressed air piping, while the arranged on the base box and linked with this additional box is exchangeable with another additional box, for example with more or less compressed air connections to an additional socket with a measuring device or an additional socket with a maintenance module. Thus, an adaptation to the respective needs is readily possible. Permanently mounted on the ground components of the compressed air line system, in particular the base module or the base box, can remain on site.

The base box thus advantageously forms a base module, the at least one additional box expediently an additional module.

If the at least one additional box is mounted on the base box, the respective linking sides abut each other, preferably substantially flat, and is also a compressed air connection between the auxiliary box and the base can realized in that the compressed air Verkettungsanschlüsse are in fluid communication with each other.

Of course, both rigid and rigid compressed air piping and flexible compressed air piping may be used to connect to the base box or the auxiliary box.

The base box daisy side and the mounting side of the base box are preferably opposite sides. Thus, for example, a tower-like structure can be created. The linking side is, for example, an end face, the mounting side a bottom side of the base can. It is understood that in an alternative, not shown in detail in the embodiment concept, the base box daisy chain side can also be arranged on a side wall or on the base box, so that a lateral concatenation with one or more additional doses can be realized. The side wall, which forms the linkage side, can of course also be oblique to the mounting side of the base can. If the side wall respectively Linked side runs perpendicular to the mounting side, a flat construction mounting is possible, that is, the additional box is located next to the base box on the ground. Although it is possible, but not necessary, to attach the additional box also on the ground, since the connection to the ground can already be realized by means of the base box.

While the base box linking side and the mounting side of the base box are advantageously arranged on opposite end faces or are formed by corresponding end walls, the at least one compressed air connection of the base box is expediently arranged on a circumferential wall. It should be noted that, of course, at the base box as needed, other compressed air connections can be provided, so that the base box is suitable for example for the passage and / or distribution of compressed air. The respective compressed air connections can be internally connected within the basic box. An isolated, separate fluid channel arrangement is also possible, in which, for example, a respective compressed air connection is routed separately and fluidically isolated to a respective base outlet connection.

The base can and / or the at least one additional can expediently have a substantially rectangular, for example square, peripheral contour. It is advantageous if the base box and the additional box have substantially the same external contours at least in the area of their linking sides. Overall, a contour equality is at least in the contact area between the base box and arranged on her additional box not only visually appealing, but also space-saving. Disturbing projections or other obstructive contours are not present.

The additional can expediently has at least one attachment wall inclined with respect to its additional can-linking side, on which the at least one compressed-air connection is arranged. It is understood that other inclined connection walls are possible. An inclined surface as a connection wall can be realized, for example, in that the additional socket housing is pyramid-shaped or truncated pyramidal. Also a spherical shape is conceivable. A pyramid or a truncated pyramid or a partial sphere having a substantially square base side serving as a concatenation side is particularly preferable. This geometry saves space while simultaneously providing numerous inclined connection walls, on which, for example, in each case a compressed air connection, a measuring device or the like is arranged. An inclined connecting wall has the advantage that the connected compressed-air pipeline, usually a flexible compressed-air pipeline, can be laid diagonally forward in the direction of the consumer.

It is understood that advantageously also on one of the Zusatzdosen-concatenation side opposite end wall of a supplementary socket housing the additional box a compressed air connection, the compressed air measuring device or the above-mentioned maintenance device can be arranged.

The maintenance device which can be arranged on an additional can according to the invention comprises, for example, a filter, an oiler, a dryer or a separation device or a combination of at least two of the aforementioned functional elements.

In the compressed air measuring device, which can measure, for example, a temperature, a humidity, a Ölungsgrad or the like, is a wired or preferably a wireless communication concept advantageous. The can device expediently has a transmitting device, which is arranged, for example, on the additional can, in order to send wireless or wired measurement data of the compressed-air measuring device. Alternatively or in combination with this, a display device for displaying the respective measurement data is also advantageous. The wireless concept has the advantage that no connecting lines between the compressed air measuring device or the can device and a control for the compressed air line system must be laid.

Also with respect to the electrical power supply, which could be necessary for the measuring device or the maintenance device, a self-sufficient concept is advantageous. The can device has expediently an electric generator for generating electrical energy for the measuring device and / or the maintenance device. The electric generator is operated for example by means of compressed air, which is guided in the can device to the generator. A photovoltaic concept is particularly easy to implement.

The interlinking sides of the base can and the at least one additional can expediently have corresponding codings, for example plug-in codings, projections or the like. Thus, for example, a rotationally correct installation can be ensured. But also a coding to the effect that the Verkettungsanschlüsse to the additional box and the base box match each other, which is in the sense of a pressure tightness is possible by means of at least one encoding.

A particularly simple installation of the base box is possible if they have at least one from the mounting side to a free when mounting on the ground side channel for inserting a for mounting the base box Having on the ground provided mounting bolt. This free side is expediently the chaining side to which the additional box is arranged after mounting the base box on the ground. Thus, therefore, the mounting means or heads of the mounting bolts are covered by the additional box when it is arranged on the base box. It is understood that, for example, eyelets or the like can project laterally before a basic contour of the base can, through which then corresponding mounting bolts or screws can be pushed.

The linking-fastening means suitably comprise latching means, connector means or screw means or combinations of the aforementioned means. For example, plug-in receptacles and plug-in projections, which mesh in the assembled state, are provided. A bayonet-type locking, in particular when connecting the linking terminals, is readily possible.

However, screwing means are particularly easy to implement, with at the same time a firm connection between the additional can and the basic can. The screw means suitably comprise at least one interlinking passageway extending from the supplementary box linking side of a free side of the at least one supplementary box, through which a mounting bolt for mounting the additional box to the base box or to another additional box located between the currently mounted supplementary box and the base box. This at least one passage chain passage can also be hidden by placing another additional box.

The linking passage channel expediently aligned when the additional box and the base box abut each other with their concatenation sides, with a screw on the base box.

Thus, the additional box is particularly easy screwed to the base box.

But it is also possible that the interlinkage passageway in the aforementioned, applied to the base box condition is aligned with a passageway of the base box, which extends from the interlinkage side to the mounting side of the base box. Thus, it is possible, for example, hindurchzustecken a mounting bolt both through the additional box and through the passage of the base box and anchored in the ground, for example, screwed into this.

In the interlinkage passageways and the passageways of the base can it is advantageous if at least two, preferably three or four, are present at least in each case.

The can body of the additional can and / or the base can or the respective can body are expediently substantially hollow in their interior, apart from compressed air channels, which are necessary between the compressed air connections and the Verkettungsanschlüssen. In the cavities, however, expediently at least one or more reinforcing ribs are arranged. At least one through-channel or one interlinkage passage of the additional box or the base box is advantageously arranged on such a reinforcing rib. This creates a stable, resilient structure overall.

At least one compressed air connection, preferably all compressed air connections, of the can device have a screw receptacle for screwing in a pipe coupling component, for example a quick coupling. The coupling component is used to connect a compressed air pipeline and can of course also one or more Have valves to shut off. Thus, it is possible, for example, to close the coupling component in order to remove the compressed air pipeline and / or to carry out assembly work on the can device, for example, to arrange a new additional module to the base can. It is understood that the coupling component can also be fixedly mounted on a respective compressed air connection of the can device.

Preferably, sealing means, for example O-rings or plastic seals, are advantageous at a respective linking connection of the additional box and / or the base box.

A self-closing closure device is expediently provided on one or more compressed air connections and / or on at least one of the linking connections of the base can or the additional can. The closure device is preferably spring-mounted or spring-mounted. Advantageously, the closure device is opened by connecting a compressed air component, for example a respective other base can or additional can, a coupling component, such as a quick coupling, or the like and closes automatically when removing the respective compressed air component. The closure device can also be actuated by otherwise outflowing compressed air. The closure device comprises, for example, a movable ball, as is usual with valves, a cap, a lid or the like.

Although in a particularly preferred embodiment of the basic box only a single basic box-Verkettungsanschluss is provided for fluid communication with a arranged on the daisy side auxiliary box. But there are also configurations of the can device possible, in which two or more basic box daisy-chain connections are appropriate. Each of the basic outlet manifold connections is equipped with a compressed air connection connected to the base box, wherein the compressed air connections and the base outlet manifold connections are fluidly isolated from each other or separated. In any case, only a fluid connection between on the one hand to the respective base box linking connection and on the other hand the associated compressed air connection. Thus, it is possible, for example, to conduct a fluid connection via the additional box. This is advantageous, for example, when the additional can is to be switched, so to speak, into a flow connection between a first and a second compressed air connection of the base can, for example for measuring purposes and / or for maintenance purposes.

The at least one additional box may also have a plurality of additional socket linking terminals, for example for connection to the aforementioned two or more basic box linking terminals. But it is also possible that the additional box in turn is provided for further linking with one or more additional doses. In that case, it is advantageous if at least one additional socket linking connection is provided on each linking side of the additional box, for example on mutually opposite additional box linking sides.

In the following described in detail can devices 10a, 10b and 10c partially identical or similar components are provided with the same reference numerals. Differences are indicated by lowercase letters a, b and c. Since a respective can-type device according to the invention can be assembled from a plurality of individual modules, basic cans or additional cans described in part in connection with one exemplary embodiment can also be used without difficulty in a can device according to another exemplary embodiment without this being explained in detail. Furthermore, the illustrated can variants are of course only By way of example, variants and combinations of different features are of course readily feasible.

The can devices 10a, 10b, 10c each have a base can 11a, 11b and 11c, which is intended for mounting on a substrate 12, for example a wall. The base box 11a, 11b, 11c lies with a mounting side 13 on the substrate 12 substantially flat. On one of the mounting side 13 opposite base boxes daisy chain side 14 additional sockets 15a-15c, 16 optionally detachable can be arranged, with additional box-linking sides 17 then the base boxes-concatenation sides 14 and suitably abut against these at least partially flat. The basic boxes 11a-11c form basic modules, so to speak, which are suitable for underground mounting or wall mounting, while the additional boxes 15a-15c, 16 form additional modules which are mounted on the front side of the basic boxes or base modules in the exemplary embodiment. While the basic cans 11a-11c can remain fixed on site, that is to say on the base 12, the additional cans 15a-15c, 16 are interchangeable components, as will become clear below.

• Die eigentliche Druckluftverteilung beziehungsweise der Anschluss von Druckluftverbrauchern ist an einer der Zusatzdosen 15a, 16 möglich, die jeweils Druckluft-Anschlüsse 19 zum Anschluss weiterer Druckluftrohrleitungen 22 aufweisen. Die Zusatzdose 15a hat beispielsweise insgesamt vier Druckluft-Anschlüsse 19, die Zusatzdose 16 drei Druckluft-Anschlüsse 19. Es versteht sich, dass auch Zusatzdosen mit beispielsweise nur einem Druckluft-Anschluss, zwei Druckluft-Anschlüssen oder mehr als vier Druckluft-Anschlüssen 19 möglich sind. Ferner wäre auch eine Blind-Zusatzdose oder ein Deckel möglich, die gar keinen Druckluft-Anschluss aufweist und lediglich die Basisdose 11a-11c verschließt.

The basic cans 11a-11c have compressed air connections 18 for connection to a stationary, for example, attached to the substrate 12 pipeline network of a compressed air line system 20. Now, for example, at one of the base cans 11a, 11b or 11c, a further compressed air connection may be provided to the one example flexible compressed air pipeline can be connected. If, however, further compressed air connections are required, one would have to replace the respective basic can 11a, 11b or 11c, for which then, for example, the compressed air pipelines 21 would have to be depressurized. However, this is readily avoidable with the help of the can devices 10a or 10a ':

• The actual compressed air distribution or the connection of compressed air consumers is possible at one of the additional cans 15a, 16, each having compressed air connections 19 for connecting further compressed air pipelines 22. The additional box 15a has, for example, a total of four compressed air connections 19, the additional box 16 three compressed air connections 19. It is understood that additional cans with, for example, only one compressed air connection, two compressed air connections or more than four compressed air connections 19 are possible , Furthermore, a blind additional box or a lid would be possible, which has no compressed air connection and only the base box 11a-11c closes.

In principle, it would be possible for the compressed-air pipelines 21, 22 to be fastened directly in compressed-air connections of a basic can or additional can according to the invention. For example, one could provide a corresponding clamping or coupling device there. In the exemplary embodiment, for the connection of the compressed air pipelines 21, 22, for example, pipe coupling components 23, preferably quick couplings 24, are provided, which are releasably attachable to the compressed air connections 18, 19. For example, threads, bayonet mountings or the like are provided on the compressed air ports 18, 19 to secure the pipe coupling components 23 therein. By way of example, only a single quick coupling 24 is shown. Instead of a quick coupling 24 could of course also another connection component, preferably provided with a shut-off connection component, be provided, so that, for example, the basic cans 11a, 11b or 11c can be depressurized for a change of an additional box.

This is for example also advantageous if the additional box 15a or 16 against one of the additional cans 15b or 15c should be replaced. The additional box 15b includes a measuring device 25, for example for measuring a compressed air flow, a temperature, a pressure or a differential pressure, a degree of humidity or a degree of degree or the like. The additional can 15 c comprises a maintenance device 26, for example a filter, an oil separator or an oiler, a dryer or the like. Thus, the can devices 10a, 10b and 10c are universally applicable and can not only realize the function of a distribution system, which is already flexible due to the different number of compressed air connections having additional doses, but also realize very different functionalities, for example, perform measuring functions and / or maintenance functions , It is understood that in a measuring additional box, a maintenance unit can be attached or that a measuring or maintenance additional box can also fulfill the function of a compressed air supply can, for example if there is another, suitable for connecting a compressed air pipeline compressed air connection is.

The piping can system according to the invention is not only extremely flexible, but also easy to install and save space in use. The basic cans 11a, 11b and 11c can be fastened to the substrate 12, for example by means of mounting bolts 27. The base boxes 11a-11c have passageways 28 for the insertion of the mounting bolts 27, which protrude in front of the mounting side 13 and into the substrate 12 are screwed. The passageways 28 are arranged in an inner space 30 of a base box housing 29 of the respective base box 11a-11c. Thus, therefore, no through-openings or other mounting parts are visible outside the base boxes 11-11c. This is not only visually appealing, but also facilitates the care of the cans devices 10a-10c, especially in dirt-intensive environment. The passageways 28 extend For example, in corner regions of the base box housing 29 and are arranged between each two adjacent peripheral walls 31. The through-channels 28 each extend from the base box-linking side 14 to the mounting side 13. It is understood that more or fewer than four through-channels 28 are readily possible.

At one or more of the peripheral walls 31, a compressed air connection 18 is arranged, with which the stationary compressed air line system 20 remaining on the base 12 can be connected to the base cans 11a, 11b and 11c. Thus, therefore, basic cans are possible in which at least one peripheral wall, on two or more peripheral walls or on all peripheral walls at least one compressed air connection or multiple compressed air connections can be arranged. For example, the base box 11b has only one compressed air connection 18.

The base box 11a has, for example, four compressed-air connections 18, which likewise lead from the compressed-air connection 18 to a linking channel 33 in the inner space 30 of the base-box housing 29. Thus, all compressed air connections 18 communicate with each other via the linking channel 33.
One of the compressed air connections 18 can serve, for example, as a compressed air input, while the other compressed air connections 18 are provided as compressed air outlets.

The base box linking terminal 34 is provided on the base box daisy side 14 of the base box 11a, 11b. In the present case, the linking connection 34 lies in the center of an end face 35 of the base box 11a, 11b or centrally on the base box linking side 14. The base box linking connection 34 is provided with a seal or sealing arrangement 36, for example of flexible material, in particular rubber or flexible plastic. The seal 36 is preferably in front of the end face 35, but in another embodiment could also be flush therewith.

In the center of the additional socket linking side 17, an additional socket linking connection 37 for connection to the basic socket linking connection 34 is arranged. The additional socket linking connection 37 has a recess 38, preferably circular, for receiving the projection 36 designed as a projection, which in the assembled state bears tight against a contact surface 39 of the additional socket linking connection 37. Thus, by attaching the additional box 15a, 15b or 16, a tight connection to the base box 11a, 11b produced. The contact surface 39 is, for example, an annular, end-side contact surface. It goes without saying that a peripheral seal would also be readily possible and / or that a connection projection engaging in a base box could be provided at a respective linking connection on an additional box.

The additional socket linking connection 37 forms an opening of a linking channel 40, which is arranged in an inner space 41 of the additional socket housing 42a, 42b or 43 (additional box 16). The linking channel 40 also serves, for example, as a distribution channel, to which compressed air channels 44 in the interior 41 of the additional cans 15a, 16 are connected, which in turn open into the compressed air connections 19. When configured as a load cell additional box 15 b of the linking channel 40 leads to the frontally arranged measuring device 25th

While the basic cans 11a, 11b and 11c are essentially closed only by their peripheral wall 31, but have an open interior 30 on the mounting side 13 and the linking side 14, the additional cans 15a-15c, 16 are open only on their linking side 17, otherwise but closed. in the In the area of the linking side 17, the additional cans 15a-15c, 16 have a peripheral contour 48 corresponding to a peripheral contour 47 of the basic cans 11a-11c, so that the basic cans and additional cans "fit together". This ensures that the basic cans 11a, 11b are closed, as it were, at the front by the attached additional cans 15a, 15b, 16. The circumferential contours 47, 48 are rectangular, in the present case even substantially square. Advantageously, the corner areas of the basic boxes and additional boxes are rounded to avoid sharp edges

The additional cans 15a-15c, 16 have a truncated pyramidal shape. From a peripheral wall 49 forming the peripheral contour 48, which is substantially aligned with the peripheral wall 31 of the base box 11a-11c, inclined side walls 45 extend to an end wall 46. The walls 45, 46, 49 are in one piece here.

It should be noted at this point that expediently the additional socket housings 42a-42c, 43 as well as the basic socket housings 29 are expediently produced in one piece in a casting process or injection molding process. Preferably, a production is essentially made of plastic. Conveniently, threads or other connection areas for piping-coupling components, e.g. Quick couplings 24, made of stronger metallic material. For example, this can be provided in the can body 29, 42 and 43 injected or overmolded metal thread.

Both the end wall 46 and the inclined side walls 45 form connecting walls 50, on each of which a compressed air connection 19 can be arranged. Each of the walls 45, 46 is thus suitable for a compressed air connection 19, so that the additional cans 15a, 16, for example, with none and arbitrarily many may be provided between one and five compressed air connections 19. The compressed air connections 19 are easily accessible, since they are arranged either obliquely forward or even directly frontally on the end wall 46.

For mounting the additional sockets 15a-15c, 16 to the respective base box 11a-11c, these are placed on the respective base box, so that their chaining side 14 is completely covered. As a result, both the fluid connection between the linking terminals 34, 37 and a mechanical closure of the interior 30 otherwise open on the linking side 14 are ensured. The respective can device 10a-10c is closed with it. For secure and secure attachment continue then mounting bolts 51 which extend from an outside of the auxiliary socket housing 42a-42c, 43 to the respective chaining side 17. The interlinking passageways 52 are arranged, for example, in the respective corner regions between two inclined side walls 45. In order that heads of mounting bolts 51, which form components of linking attachment means 85 as screwing means 86, do not protrude in front of an outer contour of the respective additional socket housings 42a-42c, 43, extended areas are provided on the input side to the linking passageways 52. Consequently, the mounting bolts 51 do not disturb both mechanically and visually in the mounted state. In FIG. 7 the mounting bolts 51 are not shown for the sake of simplicity.

In the basic box housings 29 and also the additional box housings 42a-42c, 43 consistent lightweight construction is realized, that is, the interior spaces 30 and 41 are substantially hollow, apart from acting as a reinforcement compressed air channels 32, 40 and the Verkettungskanälen 33, 44. In addition is in the interiors 30, 41 each still a Verrippungsstruktur provided, extending from the respective peripheral or outer wall to the linking channels 33, 44 extends towards. In the basic box housings 29, these are, for example, four reinforcing ribs 53 extending between the outer corner areas of the peripheral wall 31 and the central concatenating channel 33, and the reinforcing ribs 54, which are also diagonally between the outer corner areas of the peripheral wall 49 and the central concatenating channel 40, in the auxiliary box 42a-42c extend. The reinforcing ribs 53, 54 serve simultaneously as a support base for the interlinkage passageways 52 and with those on the side of the base box housing 29 in the mounted state aligned screw receptacles 56. The screw 56 are preferably configured as passageways 55, so that it is possible correspondingly long mounting bolt 51 through the Chaining passage passages 52 and the base can passageways 56 through to the ground 12 to insert and screw into this. Due to the expediently used plastic material for the base box housing 29, at least in the region of the passage channels 55 or screw receptacles 56, it is possible that the mounting bolts 51 when screwing into the base box housing 29 cut a thread in the through channels 55 itself. It is understood that there also prepared screw thread, for example, metric thread, metallic thread, screw inserts, bushes or the like, can be provided, which ensures a particularly solid and reliable fit while easy installation. The screw receptacles 56 could (not shown) include, for example, with plastic material overmolded metal inserts.

As a further support and Verrippungsmaßnahme is on the mounting side 13 facing side of the linking channel 33, a support wall 57, preferably an annular support wall arranged. The support wall 57 and the reinforcing ribs 53 expediently merge into one another.

The basic cans 11a-11c are supported on the base 12 with their circumferential walls 31, the reinforcing ribs 53 and the support wall 57, which preferably form an integral unit. It is understood that a punctual support is possible. Furthermore, a base can also be completely closed on its mounting side (not shown).

Furthermore, the peripheral wall 49 of the respective additional box is supported on the peripheral wall 31. The reinforcing ribs 54 are expediently flat on the reinforcing ribs 53 in the assembled state, so that optimal support is ensured even in the inner region of the respective basic box-additional box combination.

Thus, it is therefore advantageous if a base can according to the invention and an additional can according to the invention (or linked additional cans) have mutually corresponding, in the assembled state substantially flat superimposed Verrippungsstrukturen. Furthermore, it is expedient if, as in the exemplary embodiment, interlinkage passageways, for example interlinkage passageways 52, and corresponding screw receptacles or passageways (55, 56) in the mounted state have peripheral walls or channel walls which abut each other substantially flat.

Optionally, to e.g. on the auxiliary box 15a and the base box 11a encodings 80, 81, e.g. corresponding plug receptacles and plug-in projections, be provided, which engage with each other to a rotationally correct installation.

The concept according to the invention also makes it possible to link not only one but several, for example two or three, additional cans with each other or as in the exemplary embodiment stack each other. This is, for example, in the can device 10a 'according to FIG. 5 the case.

Between the additional box 15a forming an end box and the base box 11a to be fastened to the base 12, a further additional box 58 is layered. The additional box 58 essentially corresponds to the base box 11 a, that is to say it has a peripheral wall 59 whose contour corresponds to the peripheral wall 31.
Furthermore, one of the base can 11a facing concatenation side corresponding to the concatenation side 17 of the auxiliary box 15a configured, that is, for example, has a recess 38 for receiving the seal 36 or other connection projection, while the opposite, the additional box 15a facing concatenation side of the basic box daisy chain side 14th equivalent.

The additional box 15b forms, so to speak, a measuring device which can be attached to the base box 11b and has a sensor inside, for example a dew point sensor, a flow sensor or the like, which is in fluid communication with the linking channel 40 or the base box linking connection 34. The sensor 60 generates measured data which the measuring device 25 displays, for example, by means of a display device 61. The measuring device 25 may be arranged, for example, on an extension 62, if the space available in the interior of the additional socket housing 42b is insufficient. Otherwise, a more compact design could also be provided, for example in the manner of the additional can housing 42a, 43. However, the measurement data of the sensor 60 can also be sent by means of a preferably wireless transmitting device 63, for example via Bluetooth, wireless LAN, industrial LAN or the like.

Electrically, the measuring device 25 is self-sufficient. To generate electricity, for example, is a compressed air-driven electric generator 64th

The can device 10c has one of the base cans 11a, 11b fluidly generally divergent base can 11c, in which at least two separate compressed air ducts between on the one hand a compressed air connection for the compressed air line system 20 and on the other hand, a basic box-daisy-chain connection are realized (in basic doses according to the invention, of course several such channel guides be realized). For example, arranged inside the base box 11a compressed air channels (not visible) for the fluidic connection of arranged on a peripheral wall 31 compressed air connections 65, 66, each with a basic box-Verkettungsanschluss 67, 68 are arranged. Between the connection combinations of connections 65, 67 and 66, 68, so to speak, there is a fluidic separation plane 69, so that the compressed air connection 65 is in any case connected only to the base outlet connection 67 and the compressed air connection 66 only to the base outlet connection 68.

As a result, it is possible for compressed air flowing into the compressed air connection 65, for example, to flow out of the base-outlet linking connection 67 and to flow into the maintenance device 26 via a supplementary can-linking connection which is not visible in the drawing. There, for example, the compressed air flows through a filter 70, in order subsequently to flow into the base-outlet linking connection 68 via a likewise not visible additional-dose linking connection and to flow out of the compressed-air connection 66. A replacement of the maintenance device 26 against another is easy, since only the auxiliary can 15 c is to be replaced with another, for example, contains a filter or a dryer.
