Opfindelsen angår et lageranlæg omfattende flee ved siden af hinanden anbragte hyldestativer og af den i krav l's indledning angivne art.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a storage facility comprising a shelf adjacent to each other and of the kind specified in the preamble of claim 1.

Et kendt anlæpg af den ovenfor angivne art er beskrevet i tysk fremlæggelsesskrift nr. 2.020.037. I dette anlæg har hvert hyldestativ en mellem højregang og venstregang omskiftelig elektrisk motor, samt kun påvirkningsorgan for start af flyttebevægelsen. Man har herved opnået, at ved en enkelt ma-nøvrering af påvirkningsorganet på et ved siden af en ønsket betjeningsgang værende hyldestativ vil alle hyldestativer, der skal flyttes automatisk, begynde deres bevægelse i den rigtige retning. Hvert hyldestativ har to for de respektive forskyd-ningsretninger arrangerede omkoblingsorganer, som kun indkob-ler motoren for bevægelse ved en forudbestemt mindste afstand mellem hyldestativerne. Disse omkoblingsorganer bestemmer også slutstillingerne for hvert hyldestativ, således at hvert forskydningsforløb først påbegyndes når ved siden af liggende hyldestativer i forskydningsretningen fjernes fra dette hyldestativ, og afbrydes når hyldestativet p&ny er kommet i kontakt u Vi med et ved siden af værende hyldestativ.A known attachment of the kind mentioned above is described in German Patent Specification No. 2,020,037. In this system, each shelf rack has an electric motor, alternating between right and left, and only actuating means for starting the moving movement. It has been achieved hereby that, by a single actuation of the actuating member on a shelf stand adjacent to a desired operating step, all shelf stands to be moved automatically begin their movement in the right direction. Each shelf rack has two switching means arranged for the respective shear directions which only engage the motor for movement at a predetermined minimum distance between the shelf racks. These switching means also determine the final positions of each shelf rack, so that each shear course is only started when adjacent shelf racks in the shear direction are removed from this shelf rack and interrupted when the shelf rack has once again come into contact with a shelf next to it.

I elektrisk henseende har det kendte anlæg imidlertid en kompliceret opbygning og den valgte elektriske kredslabsløsning kræver mange komponenter, såsom relæer, omskiftere og tilsva-25 ende dele.However, in the electrical sense, the known system has a complicated structure and the chosen electrical circuit solution requires many components such as relays, switches and similar parts.

Opfindelsen har til formål at opnå en funktion i hovedsagen svarende til den, der opnås med det kendte anlæg, men hvor den elektriske kredsløbs løsning er mindre kompliceret. Dette for-30 mål er opnået ved, at anlægget ifølge opfindelsen er ejendommelig ved det i den kendetegnende del af krav 1 anførte.The invention has for its object to achieve a function substantially similar to that obtained with the known system, but where the solution of the electrical circuit is less complicated. This object is achieved in that the system according to the invention is characterized by the features of the characterizing part of claim 1.

I praksis foretrukne udførelsesformer og enkeltheder fremgår af det i den kendetegnende del af de uselvstændige krav _ _ anførte.In practice, preferred embodiments and details are set forth in the characterizing part of the dependent claims.

Opfindelsen beskrives nedenfor på grundlag af et udførelseseksempel vist på tegningen, der viser et koblingsskema for et lageranlsg ifølge opfindelsen.The invention is described below on the basis of an exemplary embodiment shown in the drawing which shows a wiring diagram for a storage device according to the invention.

Det på tegningen viste lageranlæg af den art, hvor reoler eller hyldestativer kan anbringes tæt sammenstillet, er mekanisk set af kendt art. Det omfatter således et antal forskydelige skematisk viste hyldestativer 10, 11, 12, der hver kan flyttes 5 mellem to endestillinger. De bevægelige hyldestativer indrammes i forskydningsretninger af to faste,skematisk viste,hylde-stativer 13 og 14. De bevægelige hyldestativer er opbygget ifølge kendt teknik og disses konstruktion beskrives derfor ikke nærmere. Dog kan i korthed nævnes, at kendte hyldestati-10 ver er anbragt på vogne, hvis hjul drives af en i hvert hyldestativ anbragt elektrisk motor 15.The storage system shown in the drawing, of the kind in which shelves or shelves can be placed tightly assembled, is mechanically of a known type. Thus, it comprises a plurality of displaceable schematically shown shelf stands 10, 11, 12, each of which can be moved 5 between two end positions. The movable shelf racks are framed in shear directions by two fixed, schematically shown, shelf racks 13 and 14. The movable shelf racks are constructed in accordance with the prior art and therefore their construction is not described in detail. However, it should be mentioned briefly that known shelf stands are placed on wagons whose wheels are driven by an electric motor 15 arranged in each shelf rack.

Motorerne 15 er i dette udførelseseksempel en for venstre- eller højregang omskiftelig asynkronmotor med kondensator 16. Hyldestativene 10, 11 og 12 er permanent forbundne med hinan-The motors 15 are in this embodiment an asynchronous switchable asynchronous motor with capacitor 16. The shelf racks 10, 11 and 12 are permanently connected to each other.

Pasen er forbundet via en kontakt 19a i et relæ 19, som desuden er udrustet med en selvholdningskontakt 19c. Relæets funktion OQ skal forklares nærmere i det følgende.it and is further connected to phase and zero in a single phase AC voltage supply for 220 V via conductors 17 and 18. The passport is connected via a contact 19a in a relay 19, which is furthermore equipped with a self-holding contact 19c. The function of the relay OQ is explained in more detail below.

Hyldestativene 10, 11 og 12 har to styres trømkredsløb, af hvilke det ene, 20, indkobler motoren 15 for venstregang, og hvor det andet, 21, indkobler motoren for højregang. I styrekredsløbet 20 indgår en kontakt 22, som mekanisk er koblet til 2 5 en ved hyldestativets venstre side beliggende skematisk vist manøvreliste 23, som er indrettet til at kunne påvirkes af det til venstre derfor beliggende hyldestativ,eller for hyldestativet 10 det faste hyldestativ 13. Styrestrømkredsløbet 21 omfatter på tilsvarende måde en kontakt 24, som mekanisk er kob- 3 0 let til en manøvreliste 25. Motorerne er via en leder 26 forbundet til lederen 18 og videre via strømkredsløbene 20, 21 og en leder 27 forbundet til lederen 17. Styrestrømkredsløbene er derved samiaer.kohlede ved hjælp af en ledar 28.Shelf racks 10, 11 and 12 have two controlled current circuits, one of which, 20, engages the motor 15 for left-hand drive, and the other, 21, engages the motor for right-hand drive. In the control circuit 20, a contact 22, which is mechanically coupled to 25, includes a schematically shown maneuvering list 23 located on the left side of the shelf rack, which is adapted to be influenced by the shelf rack located on the left, or for the shelf rack 10 the fixed shelf rack 13. The control current circuit 21 similarly comprises a switch 24 which is mechanically coupled to a maneuvering list 25. The motors are connected via a conductor 26 to the conductor 18 and further via the current circuits 20, 21 and a conductor 27 to the conductor 17. The control current circuits are thus Sami cooled by means of a conductor 28.

35 Som ovenfor angivet tilføres fasespændingen til lederen 17 via relækontakten 19a. Relæet 19 er via en leder 29 forbundet med lederen 18 og dermed til 0 V. Relæet er endvidere via en kontakt 30a j et tidsrelæ 30 forbundet til en leder 31. Denne 3As indicated above, the phase voltage is applied to the conductor 17 via the relay contact 19a. The relay 19 is connected via a conductor 29 to the conductor 18 and thus to 0 V. The relay is further connected via a contact 30a j to a time relay 30 to a conductor 31. This 3

forbinder relæet over et til antallet af bevægelige hyldestativer svarende antal parallelle strømkredsløb med en leder 32, som via en normalt sluttet kontakt 19b i relæet 19 er forbundet til fasespændingen. Et sådant strømkredsløb indbefater 5 eksempelvis en i hyldestativet 12 af et relæ 33 styret kontakt 33a og et i hyldestativet 11 arrangeet påvirkningsorgan 34 for start af et forskydningsforløb. Alle de bevægelige hyldestativer omfatter sådanne påvirkningsorganer 34 og relæer 33 med relækontakter 33a, medens det venstre faste hyldestativ 13 .10 kun omfatter ét påvirkningsorgan 34 og det faste hyldestativ 14 helt mangler et påvirkningsorgan og relæ med relækontakt. Relæet 33 omfatter tillige to kontakter 33b og 33c af hvilke kontakten 33b indgår i styrekredsløbet 20 og kontakten 33c indgår i styrekredsløbet 21. Ved ikke-aktiveret relæ er kon-15 takten 33b sluttet, medens kontakten 33c er afbrudt, hvad der indebærer, at motoren 15 ved spændingsløst relæ er forberedt på bevægelse mod venstre.connecting the relay over a number of parallel shelf racks corresponding to the number of movable shelf racks to a conductor 32 which is connected to the phase voltage via a normally closed contact 19b in the relay 19. Such a current circuit includes, for example, a contact 33a controlled in the shelf rack 12 by a relay 33 and an actuator 34 arranged in the shelf rack 11 for starting a shear course. All of the movable shelf racks include such actuating means 34 and relays 33 with relay contacts 33a, while the left fixed shelf rack 13 .10 comprises only one actuating member 34 and the fixed shelf stand 14 completely lacks an actuating member and relay with relay contact. The relay 33 also includes two switches 33b and 33c of which switch 33b is included in control circuit 20 and switch 33c is included in control circuit 21. On non-activated relay, contact 33b is closed while switch 33c is disconnected, which means that the motor 15 in case of non-voltage relay is prepared for movement to the left.

Lageranlægget er på sædvanlig måde beskyttelsesjordet via en leder 35. Lageranlægget fungerer på følgende måde.As usual, the storage facility is the protective ground via a conductor 35. The storage facility operates as follows.

Ved ikke-aktiveret relæ 19, er relækontakten 19b sluttet, hvad der indebærer, at i anlæggets hviletilstand er lederen 32 under spænding. Det antages nu, at en betjeningsgang ønskes mellem hyldestativerne 10 og 11. Derved manøvreres det i hyldestati- 2 5 vet 10 arrangerede påvirkningsorgan 34, hvorved spænding tilføres til det i hyldestativet 11 anbragte relæ 33, hvilket trækker og slutter kontakten 33a. Derved tilføres spænding til relæet 33 i hyldestativet 12, hvorved kontakten 33a i hyldestativet 12 sluttes og fører spændingen ud på lederen 31. Der- 3 0 ved opnår relæet 19 spænding via den i hvilestilling sluttede kontakt 30a, der hører til tidsrelæet 30. Relæet 19 trækker derved og slutter kontakterne 19a og 19c. Via kontakten 19c får relæet 19 en selvholdestrøm og endvidere sættes tidsrelæet 30 under spænding. Dette kan være indstilleligt for tider mel-In the case of non-activated relay 19, the relay contact 19b is closed, which means that in the resting state of the system, the conductor 32 is under voltage. It is now assumed that an actuation is desired between the shelf stands 10 and 11. The actuating means 34 arranged in the shelf stand 10 is thereby actuated, thereby supplying voltage to the relay 33 located in the shelf rack 11, which pulls and closes the contact 33a. Thereby, voltage is applied to the relay 33 in the shelf rack 12, whereby the contact 33a in the shelf rack 12 is terminated and the voltage is applied to the conductor 31. Thus, the relay 19 generates voltage via the resting contact 30a belonging to the time relay 30. The relay 19 thereby pulling and terminating contacts 19a and 19c. Via the switch 19c, the relay 19 receives a self-holding current and, furthermore, the time relay 30 is energized. This can be adjustable at times

Den påkrævede tid afhænger af anlæggets størrelse og af 4limb 0 and for example 5 min. to ensure that the relay 19 remains drawn during the time the shelf of the shelf rack takes place. The required time depends on the size of the plant and on the 4

Den nødvendige tid for et anlæg med ti hyldestativer j maksimalt anslåes til nogle minutter.the number of shelf racks that in a given case must be increased. The required time for a plant with ten shelf stands j is estimated at a few minutes.

5 Af ovenstående redegørelse fremgår det, at relæerne 33 i hyldestativerne 11 og 12 er trukne og for relækontakterne 33b er afbrudt, og kontakterne 33c er sluttede. Hyldestativerne 11 og 12 er således forberedte til bevægelse mod højre. I hyldestativet 10 er derimod relæet 33 spændingsløst, og følgelig er kontakten 33b sluttet, medens kontakten 33c er afbrudt. Hyldestativet 10 er derfor forberedt til bevægelse mod venstre.5 It is evident from the above statement that relays 33 in shelf racks 11 and 12 are drawn and for relay contacts 33b are disconnected and contacts 33c are closed. The shelf racks 11 and 12 are thus prepared for movement to the right. In shelf rack 10, on the other hand, relay 33 is voltage-free, and consequently switch 33b is closed while switch 33c is disconnected. The shelf stand 10 is therefore prepared for movement to the left.

De nu nævnte tilstande råder, når relæet 19 trækker og via kontakten 19a tilfører spænding på lederen 17, fra hvilken via lederne 27 styrestrsmkredsløbene 21 i hyldestativerne 11 og 12, og kredsløbet 20 i hyldestativet 10 får strøm. Da kontak-The now-mentioned states prevail when the relay 19 draws and via the contact 19a supplies voltage to the conductor 17, from which via the conductors 27 the control circuits 21 in the shelf racks 11 and 12, and the circuit 20 in the shelf rack 10 are energized. Since contact

ten 24 i hyldestativet 12 ikke påvirkes af noget ved siden af værende hyldestativ, vil dette hyldestativ begynde sin for-skydningsbevsgelse mod højre, mod det faste hyldestativ 14.If shelf 24 in shelf rack 12 is not affected by anything next to shelf rack, this shelf rack will begin its displacement movement to the right, toward the fixed shelf rack 14.

Når den modsvarende kontakt 24 i hyldestativet 11 sluttes, 20 følger dette hyldestativ efter hyldestativet 12 mod højre. Afstandsmæssigt kræves kim nogle få cm. afstand mellem hyldestativerne for, at kontakterne 24 skal slutte,og tidsmæssigt indebærer dette, at hyldestativerne starter næsten samtidigt.When the corresponding contact 24 in shelf rack 11 is terminated, 20 this shelf rack follows shelf rack 12 to the right. From a distance, germ is required a few cm. distance between the shelf racks for the contacts 24 to end, and in time this implies that the shelf racks start almost simultaneously.

For hyldestativet 10 gælder, at den mulige bevægelse sker mod venstre mod det venstre faste hyldestativ 13. Imidlertid lig- 2 5 ger hyldestativet 10 allerede imod hyldestativet 13 og følgelig er kontakten 22 afbrudt. Hyldestativet 10 bliver derfor " "stående i sin stilling. Når derfor hyldestativerne 11 og 12, har nået deres højre slutstilling og kontakterne 24 atter er afbrudt, er ferskydningsforløbet afsluttet cg den ønskede be-For the shelf stand 10, the possible movement is to the left against the left fixed shelf stand 13. However, the shelf stand 10 already rests against the shelf stand 13 and consequently the contact 22 is disconnected. The shelf stand 10 therefore remains "" in its position. Therefore, when the shelf racks 11 and 12 have reached their right end position and the contacts 24 are disconnected again, the fresh shooting process is completed and the desired condition is reached.

tjeningsgang fremkommet mellom hyldestativerne 11 og 12. Når tidsrelæet efter den forudindstillede tid afbryder kontakterne 30a, falder alle de aktiverede relæer 33, ligesom relæet 19, og anlægget er gået over til sin hviletilstand.When the time relay after the preset time switches contacts 30a, all the activated relays 33 fall, as does the relay 19, and the system has switched to its idle state.
