Den foreliggende opfindelse angår en indretning til forbindelse af to af i det mindste tre stationer og af den i indledningen til krav 1 angivne art.The present invention relates to a device for connecting two of at least three stations and of the kind specified in the preamble of claim 1.

Ved kendte rørpostanlæg, ved hvilken de forskellige 5 stationer er forbundet med hinanden ved hjælp af en som føring tjenende rørledning, tilvejebringes forbindelsen mellem to stationer derved, at en beholder, der indeholder den genstand, som skal overføres, f.eks. en informationsbærer, befordres gennem rørledningen fra afsende- til modtagestatio-10 nen ved hjælp af trykluft eller vakuum. Ved hjælp af en målstyring sikres, at beholderen kommer til den ønskede modtagestation. Vil denne modtagestation nu på grund af den modtagne information træde i forbindelse med afsendestationen, så må der fra modtagestationen afsendes en beholder, der 15 indeholder en passende informationsbærer, med afsendestationen som endestation.In known pipe post plants, at which the different stations are connected to each other by means of a conduit, the connection between two stations is provided in that a container containing the object to be transferred, e.g. an information carrier is conveyed through the pipeline from the sending to the receiving station by means of compressed air or vacuum. A target control ensures that the container reaches the desired receiving station. If, due to the information received, this receiving station will contact the sending station, then a container containing a suitable information carrier must be dispatched from the receiving station with the sending station as the end station.

Ved disse anlæg består der efter optagelse af forbindelse mellem de to stationer ingen varig forbindelse. Mellem to stationer er derfor kun en forsendelsesmæssig dialog 20 mulig, idet der mellem de enkelte forsendelser eventuelt forekommer betydelige tidsmæssige mellemrum.At these facilities, there is no permanent connection after the connection between the two stations. Therefore, between two stations only a consignment dialogue 20 is possible, since there may be considerable temporal intervals between the individual consignments.

Formålet for den foreliggende opfindelse er at tilvejebringe en indretning af den indledningsvis nævnte art, som ved en enkel opbygning gør det muligt selektivt mellem 25 to af flere stationer at tilvejebringe en varig forbindelse i et frit valgbart tidsrum.The object of the present invention is to provide a device of the kind mentioned initially, which, in a simple construction, allows selectively between 25 two of several stations to provide a durable connection for a freely selectable period of time.

Dette formål opnås ifølge opfindelsen ved det i den kendtegnende del af krav 1 angivne.This object is achieved according to the invention by the embodiment of claim 1.

Ved forskydning af kugleledsledkæden til en af de 30 forskellige stillinger tilvejebringes over denne kæde en uafbrudt forbindelsesvej mellem to udvalgte stationer. Over gennemgangen i kugleledsledkæden eller over et i denne gennemgang anbragt overføringselement kan der nu i det ønskede tidsrum i begge retninger mellem disse to stationer 35 ske en informationsudveksling eller anden overføring. Da forbindelsesvejen opretholdes i hele tidsrummet, er en di- 2By displacing the ball joint link to one of the 30 different positions, a continuous path between two selected stations is provided across this chain. Over the passage in the ball joint or over a transmission element arranged in this review, an information exchange or other transfer can now take place in both directions between these two stations in both directions. Since the connection path is maintained throughout the period, a di- 2

rekte dialog mellem de to stationer mulig.direct dialogue between the two stations possible.

Anvendelsen af en rumligt bevægelig kugleledsled-kæde muliggør et i det væsentlige vilkårligt forløb af føringen. Endvidere har kugleledsledkæden den fordel, at 5 gennemgangen heller ikke bliver afbrudt ved bevægelse gennem kurver med lille radius.The use of a spatially movable ball joint link enables a substantially arbitrary course of the guide. Furthermore, the ball joint link has the advantage that the passage is also not interrupted by movement through small radius curves.

Fra PR A 1 405 164 kendes en indretning til løftning og sænkning af laster, der (i modsætning til opfindelsesgenstanden) har en krydsledskæde. Denne kæde tjener 10 i første række til belastningsoptagelse og har i sit indre en gennemgående kanal, i hvilken der forløber forbindelsesledninger og -rør. Via de sidstnævnte sker forsyningen af enten i lastkæden hængende eller stationært anbragte konstruktionsdele. Ved denne kendte lastløfte-15 indretning sker der således ingen selektiv forbindelse af to af mindst tre stationer.From PR A 1 405 164 there is known a device for lifting and lowering loads which (unlike the object of the invention) has a cross link chain. This chain serves 10 primarily for load pick-up and has in its interior a through channel in which connecting lines and pipes run. Via the latter, the supply is made of either structural parts suspended in the load chain or stationary. Thus, in this known cargo lifting device, no selective connection of two of at least three stations occurs.

Foretrukne udføreisesformer for indretningen ifølge opfindelsen er angivet i kravene 2 til 10.Preferred embodiments of the device according to the invention are set out in claims 2 to 10.

Opfindelsen skal i det følgende beskrives nærmere 20 ud fra en udførelsesform, idet der henvises til tegningen, på hvilken fig. 1 viser i ren skematisk gengivelse en indretning til tilvejebringelse af en forbindelse mellem en hovedstation og én af et antal sekundærstationer, og 25 fig. 2 i større målestok et afsnit af føringskana len med en deri anbragt kugleledsledkæde i snit.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail with reference to an embodiment, with reference to the drawing, in which FIG. 1 shows, in pure schematic representation, a device for providing a connection between a main station and one of a number of secondary stations; and FIG. 2 is an enlarged section of the guide channel with a cross-linked ball joint link therein.

Ved det i fig. 1 viste anlæg forefindes fire stedvist fra hinanden adskilte stationer 1, 2, 3, 4, som står i forbindelse med hinanden over en føringskanal 5. I det 30 indre af denne føringskanal forløber som endelig streng en kugleledsledkæde 6. Sidstnævnte er af kendt konstruktion og nærmere beskrevet i GB-OS 2 077 881. Af denne grund skal konstruktionen af denne kæde 6 kun kort beskrives med henvisning til fig. 2.In the embodiment shown in FIG. 1, four stations 1, 2, 3, 4, which are spaced apart from each other, are connected to each other over a guide channel 5. In the interior of this guide channel a ball joint link 6 extends finally, the latter being of known construction and more specifically described in GB-OS 2 077 881. For this reason, the construction of this chain 6 is only briefly described with reference to FIG. 2nd

De med 7 betegnede kædeled i kugleledsledkæden 6 består af to halvdele 7a og 7b, som er forbundet med hinanden med ringforbindelser 8. Hvert kædeled har ved den ene ende et kugleledlegeme 9 og ved den anden ende et kugleledleje 10, i 5 hvilket kugleledlegemet 9 på nabokædeleddet 7 fastholdes. Kugleledsledkæden 6 har en kanalformet gennemgang 11, der strækker sig langs dens længdeakse 6a. I denne gennemgang 11 forløber en elektrisk leder i form af et kabel 12.The chain links 7 designated in the ball joint link 6 consist of two halves 7a and 7b which are connected to each other by ring connections 8. Each chain link has at one end a ball joint body 9 and at the other end a ball joint bearing 10, at which the ball joint member 9 of the adjacent chain link 7 is retained. The ball joint link 6 has a channel-shaped passageway 11 extending along its longitudinal axis 6a. In this review 11, an electrical conductor in the form of a cable 12 runs.

Som det yderligere er vist i fig. 1, forefindes der 10 til forskydning af kugleledsledkæden 6 i føringskanalen 5 et drev 13, som har et kun skematisk gengivet kædehjul 14, der har en komplementært til kædeprofilen formet yderprofil. Kædeleddene 7 indgriber formmæssigt i yderprofilen af kædehjulet 14. Det sidstnævnte kan på ikke nærmere gengi-15 vet måde drives i modsatte omdrejningsretninger A og B.As further shown in FIG. 1, there is provided 10 for displacement of the ball joint link 6 in the guide channel 5 a drive 13 having a schematically reproduced sprocket 14 having an outer profile, which is complementary to the chain profile. The chain links 7 formally engage the outer profile of the sprocket 14. The latter can not be driven in opposite directions in opposite directions A and B.

Drevet 13 kan eksempelvis være udformet på den i europæiske patentansøgning nr. 0077467 omhandlede måde.The drive 13 may, for example, be designed in the manner disclosed in European Patent Application No. 0077467.

Til det ved den viste udførelsesform i området ved hovedstationen 1 værende drev 13 slutter sig et magasin 20 15 til kugleledsledkæden 6. Dette magasin 15 kan eksempel vis være udformet som beskrevet i CH-PS 626 027, Ved sin forreste, frie ende er kugleledsledkæden 6 forsynet med et ikke nærmere gengivet koblingsorgan 16, som er forbundet med kablet 12. Dette koblingsorgan strækker sig gennem en ikke 25 nærmere gengivet længdeslids i føringskanalen 5 og tjener til at tilvejebringe en forbindelse mellem kablet 12 og en af endestationerne 2, 3 eller 4. Ved den modsat koblingsdelen 16 liggende ende er kablet 12 til stadighed forbundet med hovedstationen 1.In the embodiment shown in the region of the main station 1, drive 13 joins a magazine 20 15 to the ball joint link 6. This magazine 15 may, for example, be designed as described in CH-PS 626 027. At its front free end is the ball joint chain 6 provided with an unspecified coupling means 16 which is connected to the cable 12. This coupling means extends through an unspecified longitudinal slit in the guide channel 5 and serves to provide a connection between the cable 12 and one of the end stations 2, 3 or 4. At the opposite end of the coupling part 16, the cable 12 is constantly connected to the main station 1.

30 I øvrigt foreligger der en ikke nærmere gengivet drevstyring, der er udformet således, at drevet 13 kan forskyde kugleledsledkæden 6 mellem forskellige stillinger, i hvilke koblingsorganet 16 befinder sig ved en af endestationerne 2, 3 eller 4. Dette kan eksempelvis ske derved, at 35 drevstyringen registrerer størrelsen af den til enhver tid fremskudte hhv. tilbagebevæg.ede længde af kugleledsl-edkæ-den 6 og sammenligner denne faktiske værdi med en forud 430 Furthermore, there is an unspecified drive control which is designed so that the drive 13 can displace the ball joint link 6 between different positions, in which the coupling means 16 is at one of the end stations 2, 3 or 4. This can be done, for example, by The drive control registers the size of the advances, respectively, at any given time. backward.the length of the ball joints 6 and compares this actual value with a prior 4

fastlagt, tilstræbt værdi. Så snart denne faktiske værdi svarer til den tilstræbte værdi, stoppes drevet 13. Endvidere er det tænkeligt ved den forreste, frie ende af kug-leledsledkæden 6 at anbringe et føleorgan til en målsty-5 ting, som melder tilbage til drevstyringen, når den frie ende af kugleledsledkæden har nået den valgte endestation 2, 3 eller 4.determined, pursued value. As soon as this actual value corresponds to the desired value, the drive is stopped 13. Furthermore, it is conceivable at the front free end of the ball joint link 6 to place a sensing means for a target control which returns to the drive control when the free drive end of the ball joint has reached the selected end station 2, 3 or 4.

I fig. 1 er kugleledsledkæden 6 vist i en stilling, i hvilken der er tilvejebragt en forbindelse mellem hoved-10 stationen 1 og endestationen 2. Over kablet 12 og koblingsorganet 16 kan der nu overføres elektriske signaler fra stationen 1 til stationen 2 og omvendt. Herved forbliver forbindelsesvejen mellem stationerne 1 og 2 bestående så længe, som kugleledsledkæden 6 befinder sig i den i fig. 1 15 viste stilling.In FIG. 1, the ball joint link 6 is shown in a position in which a connection is provided between the main station 1 and the terminal station 2. Electrical signals can now be transmitted from the station 1 to the station 2 and vice versa. Hereby, the connecting path between stations 1 and 2 remains in existence as long as the ball joint link 6 is in the position shown in FIG. 1 15.

Ønsker man nu at optage forbindelse mellem stationerne 1 og 3 eller 1 og 4, så forskydes kugleledsledkæden 6 ved hjælp af drevet 13, indtil koblingsorganet 16 har nået stationen 3 hhv. 4. I den tilsvarende stilling af kugle-20 ledsledkæden 6 er en signaloverføring mellem stationerne 1 og 3 hhv. 1 og 4 så mulig.If it is now desirable to establish a connection between stations 1 and 3 or 1 and 4, then the ball joint link 6 is displaced by the drive 13 until the coupling means 16 has reached the station 3 respectively. 4. In the corresponding position of the ball-link link 6, a signal is transmitted between stations 1 and 3, respectively. 1 and 4 as possible.

Det er ligeledes tænkeligt at forsyne kugleledsledkæden 6 med ét eller flere yderligere koblingsorganer 16, som er anbragt i en afstand fra hinanden, der svarer til 25 afstanden mellem endestationerne 2, 3 og 4. Ved et sådant arrangement ville det eksempelvis være muligt i en passende stilling af kugleledsledkæden 6 samtidig at forbinde to eller alle tre endestationer 2, 3, 4 med hovedstationen 1.It is also conceivable to provide the ball joint link 6 with one or more additional coupling means 16 which are spaced apart corresponding to the distance between the end stations 2, 3 and 4. For example, in such an arrangement it would be possible to positioning the ball joint link 6 at the same time connecting two or all three terminals 2, 3, 4 with the main station 1.

Kablet 12 behøver ikke nødvendigvis til stadighed 30 at være forbundet med en station, som det er tilfældet ved den viste udførelsesform. Således vil eksempelvis forbindelsen mellem hver station og kablet 12 kunne ske over et koblingsorgan 16.The cable 12 does not necessarily need to be continuously connected to a station, as is the case in the embodiment shown. Thus, for example, the connection between each station and the cable 12 may occur over a coupling means 16.

Der er endnu forskellige yderligere udførelsesformer 35 for den viste indretning mulige, af hvilke i det følgende kun nogle enkelte kort skal omtales.Still further various embodiments 35 of the device shown are possible, of which only some individual cards will be mentioned hereinafter.

I stedet for en endelig streng kan der også anvendes en endeløs kugleledsledkæde 6, der føres i en i sig selv lukket føringskanal 5, som det eksempelvis er beskrevet i CH-PS 621 183* 5 Føringskanalen 5 kan også have flere grene, som selektivt kan til- og frakobles ved hjælp af et omskifte-system, som det nærmere er forklaret i CH-PS 626 027 og i CH-PS 623 283.Instead of a finite strand, an endless ball joint link 6 may also be used which is inserted into a self-closing guide channel 5, as described, for example, in CH-PS 621 183 * 5. The guide channel 5 may also have several branches which can be selectively is switched on and off by means of a switching system, as is further explained in CH-PS 626 027 and in CH-PS 623 283.

Kugleledsledkæden kan naturligvis også være udfor-10 met anderledes end vist, eksempelvis på den fra DE-PS 22 20 259 kendte måde.The ball joint link can, of course, also be designed differently than shown, for example in the manner known from DE-PS 22 20 259.

I stedet for et elektrisk kabel kan der i kugleleds-ledkæden 6 ligeledes være tilvejebragt en lysleder, over hvilken lyssignaler lader sig overføre på kendt måde. Des-15 uden er det også muligt at anbringe en hulleder i gennemgangen 11, over hvilken flydende og gasformige medier samt pulver- eller støvformige eller kornede materialer lader sig overføre. Endvidere ville det også være tænkeligt at transportere egnede stykgodsmaterialer over en sådan hul-20 leder. Ved en gas- eller væsketæt udformning af gennemgangen 11 vil man i visse tilfælde kunne undlade at beklæde denne gennemgang 11 med en hulleder.Instead of an electrical cable, a ball joint 6 may also be provided in a ball joint link 6 over which light signals can be transmitted in a known manner. In addition, it is also possible to place a hole conductor in the passage 11 over which liquid and gaseous media as well as powder or dusty or granular materials can be transferred. Furthermore, it would also be conceivable to transport suitable unit goods over such a hollow conductor. In a gas- or liquid-tight design of the passage 11, in some cases it will be possible to avoid covering this passage 11 with a hole conductor.

For at undgå at lederen 12 ved bøjning af kugleleds-ledkæden 6 bliver for stærkt sammentrykket eller beskadiget, 25 er gennemgangen 11 udvidet ved gegge ender af et kædeled 7.In order to prevent the conductor 12 from bending the ball joint link 6 to become too tightly compressed or damaged, the passage 11 is extended at opposite ends of a chain link 7.

Til dette formål forefindes der både ved hvert kugleled-legeme 9 og ved hvert kugleledleje 10 et kanalafsnit 11a hhv. 11b med større tværsnit. Som vist i fig. 2 er kanalafsnittet 11a i kugleledlegemerne 9 udformet konisk udvidede 30 i retning mod det tilknyttede kugleledleje 10, mens kanal-afsnittene 11b i kugleledlejerne 10 har en cylindrisk form.For this purpose, there is a channel section 11a, respectively, at each ball joint body 9 and at each ball joint bearing 10. 11b with larger cross section. As shown in FIG. 2, the channel portion 11a of the ball joint bodies 9 is conically expanded 30 toward the associated ball bearing 10, while the channel portions 11b of the ball joint bearings 10 have a cylindrical shape.
