Opfindelsen angår et anlæg til transport og sortering af genstande, og som omfatter én langs en transportbane ført styreskinne, et antal på denne skinne bevægbare vogne, hvoraf i hvert fald en del hver har sin egen drivmotor, 5 som er monteret på en til vognen hørende ramme, samt midler til at transportere genstandene hen til et forudbestemt sted af transportbanen og aflæsse genstandene her.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a plant for transporting and sorting articles, comprising a guide rail guided along a transport track, a number of carriages movable on this rail, each of which at least one having its own drive motor 5 mounted on a carriage belonging to the carriage. frame, as well as means for transporting the objects to a predetermined location of the conveying path and unloading the objects here.

Der kendes sorteringsapparater, hvor genstande anbringes 10 på transportflader, der fremføres langs en fast bane.Sorting apparatus are known in which articles 10 are placed on conveying surfaces conveyed along a fixed path.

Disse sorteringsapparater har et antal samlestationer, hvor genstandene losses efter en passende kode i det øjeblik, hvor der lastes ved hjælp af skubbeelementer, ved tipning af transportplanet, eller på anden måde. Ved alle 15 disse kendte anlæg har vognene dog ikke-drevne kørehjul, idet vognene fremføres ved hjælp af en eller flere stationære motorer, der påvirker med vognene forbundne trækorganer, f.eks. kæder. Denne løsning anvendes især ved enkle transportbaner, f.eks. retliniede eller ret korte 20 transportbaner.These sorters have a number of collection stations where the items are unloaded according to a suitable code at the moment of loading by means of pushing elements, by tipping the transport plane, or otherwise. However, at all 15 of these known systems, the carriages have non-driven drive wheels, the carriages being driven by one or more stationary motors which actuate the pulling means associated with the carriages, e.g. chains. This solution is especially used for simple transport lanes, e.g. straight or fairly short 20 transport lanes.

Indbefatter transportbanen derimod kurvepartier, forgre ninger, skrånende afsnit eller transportbanepartier i forskellig højde, kompliceres derved hele anlægget, idet 25 det da er nødvendigt at opdele tr anspor tbanen i et antal sektioner og at tilvejebringe passende forbindelser mellem en sektion og den næstfølgende. Dette indebærer, at anlægget bliver pladskrævende, tungt og bekosteligt, og at der kræves en omhyggelig vedligeholdelse af anlægget.By contrast, the conveying path includes basket sections, branches, sloping sections or transport path sections of different heights, thereby complicating the entire plant, since it is then necessary to divide the tramline path into a number of sections and to provide appropriate connections between one section and the next. This means that the system becomes bulky, heavy and expensive, and careful maintenance of the system is required.

Skal der foretages ændringer ved transportbanen, er det ofte nødvendigt at ændre hele anlægget.If changes are to be made at the transport track, it is often necessary to change the entire system.

Opfindelsen tager sigte på at overvinde ovennævnte van-35 skeligheder ved et anlæg af den indledningsvis nævnte art. Dette opnås ved, at skinnen består af to vinkel jern med hver en vertikalt stillet og en horisontalt stillet DK 168370 B1 2 flange, hvorved de vertikalt stillede flanger er anbragt med forholdsvis lille indbyrdes afstand, og de horisontale vender bort fra hinanden, at vognen er forsynet med et antal hjulpar til at køre på vinkel jernenes horisontale 5 flanger med hjulene i hvert hjulpar løbende på hver sin side af den respektive flange, at et af hjulparrene drives af drivmotoren, mens resten er fritløbende, og at drivmotoren er udkraget ophængt i vognrammen med tyngdepunktet liggende uden for hjulparrenes understøtning.The invention aims to overcome the above-mentioned difficulties in an installation of the kind mentioned above. This is achieved by the rail being made up of two angled irons with each a vertically positioned and a horizontally positioned flange, the vertically positioned flanges being spaced relatively apart and the horizontal facing away from each other that the carriage is provided with a plurality of wheel pairs for running at the angle of the horizontal 5 flanges of the irons with the wheels of each wheel pair running on either side of the respective flange, one of the wheel pairs being driven by the drive motor while the rest being free-running, and the drive motor being extended in the carriage frame. with the center of gravity lying outside the wheel pairs support.

10 Derved opnås, at anlæggets stationære del kan gøres lettere og enklere, idet den blot består af et enkelt spor eller en skinne, hvorpå vognene kører. Trækorganer, såsom med vognene forbundne kæder bortfalder, hvorved også hele anlæggets tilpasning til nye transportkrav og anlæggets 15 ombygning forenkles og lettes både med henblik på trans-portbanens ønskede form og på den ønskede kapacitet, idet antallet af transportvogne kan ændres efter behov, uden at andre dele af anlægget skal ændres. Desuden opnås ved anlægget ifølge opfindelsen en væsentlig reduktion af 20 vedligeholdelsesarbejderne. En eventuel omstilling af an lægget fra et transportbehov til et andet kan opnås inden for meget kort tid.10 It is thereby achieved that the stationary part of the system can be made easier and simpler, simply consisting of a single track or rail on which the carriages are driven. Towing means, such as the chains associated with the carriages, lapse, thereby also simplifying and facilitating the entire system's adaptation to new transport requirements and the conversion of the system 15, both for the desired shape of the transport track and for the desired capacity, as the number of transport vehicles can be changed as needed. other parts of the plant must be changed. In addition, the plant according to the invention achieves a substantial reduction in the maintenance work. Possible switching of the system from one transport need to another can be achieved within a very short time.

I det følgende forklares opfindelsen nærmere ved hjælp af 25 tegningen, hvor fig. 1 set fra oven viser en transportvogn hørende til anlægget ifølge opfindelsen, 30 fig. 2 er et lodret snit transportanlægget, og fig. 3 er et lodret snit vinkelret på snittet i fig. 2.In the following, the invention is explained in more detail with the aid of the drawing, in which fig. 1 is a top view of a transport vehicle belonging to the system according to the invention; FIG. 2 is a vertical section of the conveyor system; and FIG. 3 is a vertical section perpendicular to the section of FIG. 2nd

Transportanlægget ifølge opfindelsen har en transportbane 35 med en styreskinne 1 bestående af to vinkeljern 2, der i indbyrdes afstand er fastgjort til en basis 3 på en sådan måde, at deres flanger 4 rager udad.The conveying system according to the invention has a conveying path 35 with a guide rail 1 consisting of two angular irons 2, which are spaced apart at a base 3 in such a way that their flanges 4 protrude outwards.

DK 168370 Bl 3 På skinnen 1 kører vogne, som i deres helhed er betegnet med 5. Hver vogn har en ramme 6 med to hjulaksler 7 med hvert sit ikke-drevne kørehjul 8. De to kørehjul kører på hver sin flange 4 på skinnen 1.DK 168370 Bl 3 On the rail 1, carriages which are designated in their entirety by 5. Each carriage has a frame 6 with two wheel axles 7, each with its own non-driven drive wheel 8. The two driving wheels each drive on their flange 4 on the rail 1 .

Til rammen 6 er endvidere fastgjort to lodrette aksler 9, på hvis ene ende er anbragt et ligeledes ikke-drevet hjul 10, som er placeret mellem vinkel jernene 2.To the frame 6 are also attached two vertical shafts 9, at one end of which is also a non-driven wheel 10, located between the angles of the irons 2.

10 På rammen 6 er monteret en elektromotor 11, som via en reduktionsudveksling 12, fig. 3, driver to tandhjul 13 på hver sin aksel 14. På akslerne 14 er desuden anbragt drivende kørehjul 15, der ligesom hjulene 8 kører på hver sin flange 4. Motoren 11 forsynes via slæbekontakter 16 15 med strøm fra strømtilførselsstænger 17, som forløber parallelt med styreskinnen 1.10 On the frame 6 is mounted an electric motor 11, which via a reduction exchange 12, FIG. 3, two gears 13 drive on each shaft 14. Furthermore, driving shafts 15 are mounted on the shafts 14, which, like the wheels 8, drive on their own flange 4. The motor 11 is supplied via tow contacts 16 15 with power from power supply rods 17 which run parallel to guide rail 1.

Over rammen 6 findes et transportplan 18 af kendt type, f.eks. bestående af en kipbar plade, en fast plade med et 20 på denne bevægeligt skubbeelement eller et omløbende transportbånd, der drives af en særskilt motor, som ligeledes forsynes med strøm via glidekontakterne fra strømtilførselsstængerne .Above frame 6 is a transport plane 18 of known type, e.g. consisting of a tiltable plate, a fixed plate having a 20 on this movable pushing element, or a circular conveyor belt driven by a separate motor, which is also supplied with power via the sliding contacts of the power supply rods.

25 Til vognenes øvre del er fastgjort opad ragende vægge 19 af et bøjeligt materiale, der dækker mellemrummet mellem to efter hinanden følgende vogne, så at der sikres kontinuitet i de planer, hvorpå genstandene lægges. Væggene 19 hindrer genstandene i at falde af. Mellem vognene findes 30 koblingsorganer 20. De således med hinanden forbundne vogne kører langs med styreskinnen 1 og bærer de genstande, der skal sorteres. Vognene skal således ikke nødvendigvis hver især have sin egen køremotor, idet visse vogne ved hjælp af koblingsorganerne 20 kan fremføres af an-35 dre vogne med egen drivmotor. På grund af vognenes egen drivmotor kan transportanlæggets stationære del blot bestå af styreskinnen, hvorved man sparer stationære moto- DK 168370 B1 4 rer og trækorganer til fremføring af vognen ved hjælp af sådanne stationære motorer. Transportanlæggets bevægelige dele er således uafhængige af dets stationære del, så at hver af disse kan ændres på ønsket vis, uden at det sam-5 lede anlæg påvirkes heraf. Transportbanen kan således nemt ændres enten ved ændring af skinnen 1’s forløb, eller ved tilføjelse af forgreninger, eller øgning eller mindskelse af skinnens længde, uden at anlæggets bevægelige dele påvirkes heraf.25 To the upper part of the carriages is mounted upwardly projecting walls 19 of a flexible material covering the space between two consecutive carriages, so as to ensure continuity in the planes on which the objects are laid. The walls 19 prevent the objects from falling off. Between the carriages are 30 coupling means 20. The carriages thus connected run along the guide rail 1 and carry the objects to be sorted. Thus, the wagons do not necessarily have to have their own driving motor, as some wagons can be driven by means of the coupling means 20 by other wagons with their own drive motor. Because of the carriage's own drive motor, the stationary part of the transport system can simply consist of the guide rail, thereby saving stationary motors and traction means for driving the carriage by means of such stationary motors. Thus, the moving parts of the conveying system are independent of its stationary part, so that each of them can be changed in the desired way without affecting the entire system. Thus, the conveying path can be easily changed either by changing the course of the rail 1, or by adding branches, or by increasing or decreasing the length of the rail without affecting the moving parts of the system.

10 På den anden side kan antallet af transportvogne øges eller mindskes i afhængighed af anlæggets ønskede kapacitet, uden at transportbanen som sådan berøres heraf. Hele anlægget vil således være maksimalt fleksibelt og meget 15 hurtigt og nemt kunne tilpasses de forskellige brugeres specielle krav. Transportanlægget ifølge opfindelsen er lettere, enklere og billigere end de hidtil kendte anlæg af denne type og kræver mindre vedligeholdelse.10 On the other hand, the number of transport vehicles can be increased or decreased depending on the desired capacity of the plant without the transport path as such being affected. The entire system will thus be maximally flexible and very quickly and easily adaptable to the special requirements of the various users. The transport system according to the invention is lighter, simpler and cheaper than the previously known plants of this type and requires less maintenance.
