Figur 1 återger schematiskt en i form av en sluten ring utförd transportbana 1 innefattande en se- rie rätlinjiga segment anbragta i rät vinkel mot var- andra. I varje rätlinjigt segment omfattar banan 1 ett par styrskenor 2, på vilka motordrivna transportfordon 3, avsedda att förflytta arbetsstycken längs banan, är styrda. Såsom framgår särskilt av figurerna 2 - 6, omfattar varje fordon 3 en plattform 4 buren av tvâ vagnar 5, som är styrda på skenorna 2. Varje vagn 5 har två par på linje ställda hjul 6, varvid varje hjulpar bärs av ett vâgbalksbildande organ 7, som självt är för- bundet med en central bäranordning 8. Anordningen 8 i varje vagn 5 är förbunden med plattformen 4 med möjlig- het till vridning omkring en vertikal axellinje 9 me- delst ett lager 10. Vagnens 5 anordning 8 bär i sin tur med möjlighet till vridning omkring axellinjen 9 461 522 en axel 11, vars undre ände skjuter ner under anord- ningen 8 och bär ett kugghjul 12 avsett att vara i in- grepp med en fast kuggstång 13 för att bestämma vagnens förflyttning längs skenorna 2. Kuggstângen 13 bärs av en fast stång 14, som går längs hela transportbanan, mellan de båda styrskenorna 2. I det inre av plattfor- men 4 är anordnade två elektriska motorer 15, vilkas axlar är sammankopplade medelst en transmission 16. De båda motorerna 15 driver under förmedling av koniska kopplingar 17 de båda till fordonets vagnar 5 hörande axlarna 11.Figure 1 schematically shows one in the form of one closed ring conveyed conveyor track 1 comprising a se- rectilinear segments arranged at right angles to each other. Other. In each rectilinear segment, the path 1 comprises one pair of guide rails 2, on which motorized transport vehicles 3, intended to move workpieces along the path, is controlled. As can be seen in particular from Figures 2 to 6, each vehicle 3 comprises a platform 4 carried by two carriages 5, which are guided on the rails 2. Each carriage 5 has two pairs of aligned wheels 6, each pair of wheels carried by a weight beam forming member 7, which is itself bound to a central support device 8. The device 8 i each carriage 5 is connected to the platform 4 with the possibility for rotation about a vertical axis 9 partly a bearing 10. The device 8 of the carriage 5 carries in its turn with the possibility of rotation about the axis 9 461 522 a shaft 11, the lower end of which projects below the device. 8 and carries a gear 12 intended to be in the grip with a fixed rack 13 to determine the carriage movement along the rails 2. The rack 13 is carried off a fixed bar 14, which runs along the entire transport path, between the two guide rails 2. In the interior of the platform but 4 are arranged two electric motors 15, which shafts are connected by means of a transmission 16. They both motors 15 operate under the transmission of conical couplings 17 both belonging to the vehicles 5 of the vehicle shoulders 11.

Såsom visas i figur 1, är de segment av banan 1 som är anordnade längs den av pilen A angivna rikt- ningen försedda med ett enda par skenor 2 på vilka varje fordons 3 båda vagnar 5 rullar. De vinkelrätt mot riktningen A orienterade segmenten av banan 1 är däremot försedda med två par styrskenor 2, på var och en av vilka en motsvarande vagn i varje fordon 3 löper.As shown in Figure 1, they are segments of the web 1 which are arranged along the direction indicated by the arrow A provided with a single pair of rails 2 on which each vehicle 3 both carriages 5 rolls. They are perpendicular the segments of the path 1 oriented towards the direction A are however, provided with two pairs of guide rails 2, on each one of which a corresponding carriage in each vehicle 3 runs.

Fordonens 3 rörelseriktning längs banan J anges med pi- larna 20 i denna figur; 2 De partier 2a av skenorna på vilka varje for- dons 3 vagnar 5 stöder när fordonet befinner sig vid slutänden av ett rätlinjigt segment av banan 1, bärs respektive av svängskivor 21, som är monterade på ba- nans fasta anordning med möjlighet till vridning om- kring en vertikal axellinje. När fordonet 3 befinner sig i nämnda ändläge, kommer varje vagns 5 axellinje 9 att sammanfalla med den motsvarande skivans 21 vrid- ningsaxel. Denna skiva bärs vridbart medelst ett la- ger 22 av en krans 23, i vars inre är anordnat ett mo- tor- och växelaggregat 24, vilket framkallar rotation av ett kugghjul 25. som är i ingrepp med en av skivans 21 undre parti buren kuggkrans 26. När fordonet 3 an- länder till änden av ett med riktningen A parallellt rätlinjigt segment, kommer på så sätt de båda vagnarna 5 att placeras på tvâ svängskivor 21 som man kan vrida 90° omkring deras axel, så att skenpartierna 2a och de 461 5.22 av dessa stödda vagnarna placeras i ställningar inrik- tade efter de motsvarande skenparen 2 på följande ban- segment vilket är vinkelrätt mot riktningen A.The direction of movement of the vehicles 3 along the path J is indicated by 20 in this figure; 2 The portions 2a of the rails on which each dons 3 carriages 5 support when the vehicle is at the end of a rectilinear segment of the web 1, is carried respectively of turntables 21, which are mounted on fixed device with the possibility of rotation around a vertical axis. When vehicle 3 is located in said end position, the axle line 9 of each carriage 5 comes to coincide with the rotation of the corresponding disc 21 axis. This disc is rotatably supported by a 22 of a ring 23, in the interior of which a motor dryer and gear assembly 24, which induces rotation of a gear 25. which is engaged with one of the discs 21 lower part carried gear ring 26. When the vehicle 3 is countries to the end of one with direction A parallel rectilinear segment, thus the two carriages come 5 to be placed on two turntables 21 which can be rotated 90 ° about their axis, so that the rail portions 2a and the 461 5.22 of these supported trolleys are placed in positions aligned after the corresponding rail pairs 2 on the following segment which is perpendicular to the direction A.

Anläggningen kan omfatta lâsanordningar av godtycklig känd typ (angivna vid 27 i figur 5) för att låsa svängskivorna i vart och ett av deras arbetslägen.The system may include locking devices of any known type (indicated at 27 in Figure 5) to lock the turntables in each of their working positions.

Utformningen av dessa lâsanordningar kommer inte att beskrivas närmare eftersom dessa anordningar inte in- går i uppfinningen.The design of these locking devices will not described in more detail because these devices are not goes in the invention.

Såsom synes i figur 4, är de partier av transportbanan som befinner sig under plattformarnas 4 nivå anordnade i en grav 29, i höjd med vars övre yta är anordnade plattor 30, vilka skjuter ut fribä- rande från gravens kant, längs plattformarnas 4 båda sidor.As can be seen in Figure 4, they are portions of the transport path located below the platforms 4 level arranged in a grave 29, at the height of whose upper surface, plates 30 are provided, which project from the edge of the grave, along both of the platforms 4 pages.

I det fall att transportbanan omfattar krökta segment (se figur 7), anordnar man två olika kuggstänger 13a, 13b för att samverka med de båda kugghjulen 12 som hör respektive till varje fordons 3 båda vagnar. Vidare är den ena av de båda kuggstänger- na (kuggstången 13b i det i figur 7 återgivna exemplet) avbruten vid det krökta partiet för att garantera ett riktigt framförande av fordonet längs detta segment trots att de båda motorerna 15 är mekaniskt sammankopp- lade.In the event that the transport path includes curved segments (see Figure 7), two different ones are arranged racks 13a, 13b to cooperate with the two the gears 12 belonging to each vehicle 3 respectively both carriages. Furthermore, one of the two racks is na (rack 13b in the example shown in Figure 7) interrupted at the curved portion to guarantee one proper driving of the vehicle along this segment although the two motors 15 are mechanically interconnected lade.

Den elektriska matningen av motorerna 15 säkerställs genom kontakt mellan en av varje vagn 5 buren släpkontakt 32 och en till den ena styrskenan 2 hörande matarskena 33.The electric supply of the motors 15 ensured by contact between one of each carriage 5 carried trailer contact 32 and one to one guide rail 2 hearing feed rail 33.

Varje svängskiva 21 är jämte de båda sken- partierna 2a utrustad med ett parti av kuggstângen 13 och ett parti av matarskenan 33.Each turntable 21, together with the two rails, is the portions 2a equipped with a portion of the rack 13 and a portion of the feed rail 33.

Såsom framgår av figurerna 4 och 6, är kor- rekt ingrepp mellan varje kugghjul 12 och kuggstången 13 garanterat av att den kuggstângen 13 bärande stång- ens 14 båda sidor angrips den ena av ett hjul 34 ochAs can be seen from Figures 4 and 6, direct engagement between each gear 12 and the rack 13 guaranteed by the fact that the rack 13 carrying the rod even on both sides, one is attacked by a wheel 34 and
