Sorterinasanlæa samt anlæg til sortering af emner, f.eks, skaldyr, såsom rater.Sorting facilities and facilities for sorting items, such as seafood, such as rates.
Opfindelsen angår et sorteringsanlæg, der omfatter et transportbånd, som 5 består af et antal parallelle transportruller, der drives af en kæde, og hvorThe invention relates to a sorting system comprising a conveyor belt consisting of a plurality of parallel conveyors driven by a chain, wherein
afstanden mellem hosliggende transportruller er indrettet til at blive varieret, Athe distance between adjacent transport rollers is arranged to be varied, A
og hvor transportrulleme består af mindst to grupper af transportruller, hvor transportrullerne i hver gruppe har ens diameter og at hver gruppe af transportruller er forbundet til hver sin drivenhed for tilvejebringelse af en 10 rotation af transportrullerne.and wherein the conveyor rollers consist of at least two groups of conveyor rollers, the conveyor rollers of each group having the same diameter and each group of conveyor rollers being connected to each drive unit to provide a rotation of the conveyor rollers.
Fra US patent nr. 6.182.832 kendes et sorteringsanlæg, der består af et transportbånd med et antal transportruller med ens diameter, og hvor transportbåndet drives af en kæde, i hvilke transportrullerne er ophængt, 15 kan afstanden mellem transportrullerne varieres ved horisontal forskydning og drejning af en transportrulle i forhold til dens nabotransportrulle. Denne afstand svarer til den maksimale størrelse af de skaldyr, der skal sorteres, og som kan passere mellem de enkelte transportruller.US Patent No. 6,182,832 discloses a sorting system consisting of a conveyor belt having a plurality of same diameter rollers and the conveyor belt being driven by a chain in which the transport rollers are suspended, the distance between the transport rollers can be varied by horizontal displacement and rotation. of a transport roller relative to its neighboring transport roller. This distance corresponds to the maximum size of the seafood to be sorted and which can pass between the individual transport rolls.
20 Forskydningen og drejningen udføres ved påvirkning af kæden med en over kæden liggende justerbar skinne, idet der på kæden er forbundet et antal arme med transportruller, som kan påvirkes af skinnen, således at transportrullerne kan forskydes indbyrdes, hvorved afstanden mellem transportrullerne kan varieres.The displacement and rotation are effected by actuating the chain with an adjustable rail located above the chain, a plurality of arms having transport rollers connected to the rail, so that the transport rollers can be displaced, thus varying the distance between the transport rollers.

Ved dette kendte transportbånd, som anvendes til sortering, kan der opstå det problem, at de skaldyr, der har en størrelse, der er lidt større end afstanden mellem transportrullerne, og som derfor skal videretransporteres, kan blive ødelagt, idet de gentagne gange delvis kan komme "i klemme” 30 mellem to transportruller.With this known conveyor belt used for sorting, the problem may arise that the seafood having a size slightly larger than the distance between the transport rollers and which must therefore be re-transported, can be destroyed repeatedly, "pinch" 30 between two transport rollers.
Et sorteringsanlæg af det i krav 1's indledning angivne type kendes fra GB patent nr. 1 566 958. Ved dette kendte sorteringsanlæg har alle 2 DK 174863 B1 transportrullerne samme diameter.A sorting system of the type specified in the preamble of claim 1 is known from GB patent no. 5666958. In this known sorting system, all 2 DK 174863 B1 conveyor rollers have the same diameter.
Det er på denne baggrund et formål med opfindelsen at tilvejebringe et sorteringsanlæg, som sikrer en hurtig indstilling af afstanden mellem 5 grupperne af transportruller, og med et stort variationsområde af afstandsindstillingen.It is therefore an object of the invention to provide a sorting system which ensures a quick adjustment of the distance between the groups of transport rollers, and with a wide range of range of the distance setting.
Opfindelsens formål tilgodeses ved et sorteringsanlæg af den i indledningen til krav 1 angivne type, som er karakteristisk ved, at transportrullernes 10 diameter i en gruppe er forskellig fra transportrullernes diameter i en anden gruppe.The object of the invention is met by a sorting plant of the type specified in the preamble of claim 1, which is characterized in that the diameter of the transport rollers 10 in one group is different from the diameter of the transport rollers in another group.
Da transportrullernes diameter i en gruppe er forskellig fra transportrullernes diameter i en anden gruppe, fås den fordel, at 15 variationsområdet for afstandsindstillingen mellem to nabotransportruller kan tilvejebringes under en lille, lodret bevægelse.Since the diameter of the transport rollers in one group is different from the diameter of the transport rollers in another group, it is advantageous that the range of variation of the distance adjustment between two neighboring transport rollers can be provided under a small vertical movement.
En særlig hensigtsmæssig udførelsesform er, som angivet i krav 2, at antallet af grupper er to.A particularly convenient embodiment is, as stated in claim 2, that the number of groups is two.
2020
Til yderligere sikring af en fejlfri sortering og transport er det en fordel, hvis, som angivet i krav 3, at drivenhedeme er indrettet til at rotere transportrullerne i grupperne med en hastighed, der kan være i retning med eller mod uret, og/eller som angivet i krav 4, at hastigheden er pulserende.To further assure flawless sorting and transport, it is advantageous if, as indicated in claim 3, the drive units are arranged to rotate the transport rollers in the groups at a speed which can be in the direction of or counterclockwise, and / or which according to claim 4, that the velocity is pulsating.
25 (25 (
Hvis, som angivet i krav 5, hver gruppe af transportruller er indrettet til at blive forskudt vertikalt, og således at forskydningen kan udføres individuelt for grupperne, bliver det muligt at vælge netop en forskydning af en gruppe transportruller i forhold til en anden gruppes transportruller, der er tilpasset 30 til en given sorteringsopgave.If, as set forth in claim 5, each group of transport rollers is arranged to be displaced vertically and so that the displacement can be performed individually for the groups, it becomes possible to select precisely one displacement of one group of transport rolls relative to another group of transport rolls. 30 are matched to a given sorting task.
En særlig hensigtsmæssig måde at påføre transportrullerne i grupperne deres hastighed er, som angivet i krav 6, at transportrullerne i hver gruppe 3 DK 174863 B1 er forsynet med et drivhjul, som er placeret uden for transportrullernes sorteringsflade, idet drivhjulene er fastgjort til aksler, der forløber gennem kæden.A particularly convenient way of applying the conveyor rollers in the groups to their speed is, as stated in claim 6, that the conveyor rollers in each group 3 are provided with a drive wheel located outside the sorting surface of the transport rollers, the drive wheels being fixed to axles which extending through the chain.
5 På denne måde bliver det relativt let at forbinde en drivenhed til en gruppe transportruller. '5 In this way, it becomes relatively easy to connect a drive unit to a group of transport rollers. '
En hensigtsmæssig udførelsesform for fastgørelse af drivhjulene hørende til en gruppe af transportruller er, som angivet i krav 7, at kæden er sam-10 mensat af parvise led, hvor der mellem hvert led i et par er anordnet et afstandshjul, gennem hvilket en aksel rager ud, væk fra transportrullemes sorteringsflade, og hvor der på akslen er fastgjort et af drivhjulene fra en gruppe af transportruller.A convenient embodiment of fastening the drive wheels belonging to a group of transport rollers is, as stated in claim 7, that the chain is composed of pairwise joints, where a spacer wheel is arranged between each joint of a pair through which a shaft protrudes. out, away from the sorting surface of the transport rollers, and where one of the drive wheels from a group of transport rollers is attached.
15 En alternativ, hensigtsmæssig måde at fastgøre drivhjulene tilhørende en anden gruppe af transportruller er, som angivet i krav 8, at der i hvert af leddene centralt er udformet en udsparing, som er indrettet til at optage en gennemgående aksel fra en transportrulle i en gruppe, idet der på enden af akslen er placeret et drivhjul fra en transportrulle i en gruppe.An alternative, convenient way of attaching the drive wheels to another group of conveyor rollers is, as stated in claim 8, that in each of the joints a recess is provided which is centrally designed to receive a through-shaft from a conveyor roll in a group , where at the end of the shaft is placed a drive wheel from a conveyor roller in a group.
2020
Med henblik på at øge fleksibiliteten ved indstilling af forskydningen i lodret retning af transportrullerne er det en fordel, hvis, som angivet i krav 9, at drivhjulene I hver gruppe har samme diameter, og at drivhjulenes diameter i forskellige grupper kan være forskellig.In order to increase the flexibility of adjusting the displacement in the vertical direction of the transport rollers, it is advantageous if, as stated in claim 9, that the drive wheels in each group have the same diameter and that the diameter of the drive wheels in different groups may be different.
2525
En relativ nem måde at forbinde en drivenhed til en gruppe transportrullers drivhjul er, som angivet i krav 10, at alle transportrullers rotation i en gruppe tilvejebringes en horisontalbevægelse. F.eks. af et bånd, der er i friktions-kontakt med drivhjulene i en tilhørende gruppe, og, som angivet i krav 11, 30 at båndet kan forskydes i vertikal retning.A relatively easy way to connect a drive unit to the drive wheel of a group of conveyor rollers is, as indicated in claim 10, that the rotation of all conveyor rollers in a group is provided with a horizontal movement. Eg. of a belt which is in frictional contact with the drive wheels of an associated group and, as stated in claim 11, 30, the belt can be displaced in the vertical direction.
Som nævnt angår opfindelsen også et anlæg.As mentioned, the invention also relates to a plant.
DK 174863 B1 4DK 174863 B1 4
Dette anlæg er nærmere angivet i krav 12.This plant is specified in claim 12.
Opfindelsen skal herefter forklares nærmere under henvisning til den på tegningen viste udførelsesform, idet 5 r fig. 1 viser en principskitse af opbygningen af et sorteringsanlæg med transportbånd ifølge opfindelsen, fig. 2 viser sorteringsanlægget ifølge opfindelsen set skråt fra en 10 ende, fig. 3 viser et udsnit med detaljer af sorteringsanlægget vist på fig.The invention will now be explained in more detail with reference to the embodiment shown in the drawing, in which FIG. 1 is a schematic diagram of the construction of a conveyor belt sorting system according to the invention; FIG. 2 shows the sorting system according to the invention seen from an end at an angle; FIG. 3 shows a section with details of the sorting system shown in FIG.
2, medens 15 fig. 4 viser detaljerne ifølge fig. 3 set fra oven.2, while FIG. 4 shows the details of FIG. 3 from above.
På fig. 1 er med 1, 1a, 1b og 1c betegnet en første gruppe af transportruller, medens 2, 2a og 2b betegner en anden gruppe af transportruller, hvor den første gruppe af transportruller har en diameter, der kan være større 20 end den anden gruppe af transportrullers diameter.In FIG. 1 is denoted by 1, 1a, 1b and 1c a first group of transport rollers, while 2, 2a and 2b denote a second group of transport rollers, the first group of transport rollers having a diameter which may be larger than the second group of the diameter of the conveyor rollers.
Som det yderligere ses, er transportrulleme placeret således, at en trans-portrulle fra den første gruppe, f.eks. 1, støder op til en transportrulle 2 fra den anden gruppe, der igen støder op til en transportrulle 1a fra den første ^ 25 gruppe osv.As can be further seen, the transport rollers are positioned such that a transport roll from the first group, e.g. 1, adjacent to a transport roll 2 from the second group, which in turn is adjacent to a transport roll 1a from the first ^ 25 group, etc.
Med pilen 5 er det antydet, at transportrullerne kan dreje med eller mod uret, og i det på figuren viste tilfælde er der valgt en omløbsretning med uret, jfr. pilene 2 og 3 ud for transportrullerne i begge grupper.The arrow 5 indicates that the transport rollers can rotate clockwise or counterclockwise, and in the case shown in the figure, a clockwise direction of rotation is selected, cf. arrows 2 and 3 next to the transport rollers in both groups.
Som det yderligere ses på fig. 1, er med pilen 18 vist, at alle transportrul-lerne bevæges mod højre ved hjælp af et kædedrev, som det forklares i forbindelse med de øvrige figurer.As further seen in FIG. 1, the arrow 18 shows that all the transport rollers are moved to the right by means of a chain drive, as explained in connection with the other figures.
30 5 DK 174863 B130 5 DK 174863 B1
Endelig er det med pilen 9 antydet, at transportrullerne med den mindste diameter kan bevæges i vertikal retning. Der er dog intet til hinder for, at transportrullerne 1,1a, 1b og 1c også kan forskydes i vertikal retning. Hen-5 sigten med den vertikale forskydning mellem transportrullerne er at kunne ændre afstanden mellem nabotransportrulleme, som det er vist ved mel- Λ lemrummet 19.Finally, with the arrow 9, it is indicated that the transport rollers of the smallest diameter can be moved vertically. However, there is nothing to prevent the transport rollers 1,1a, 1b and 1c from being displaced vertically. The purpose of the vertical displacement between the transport rollers is to be able to change the distance between the neighboring transport rollers, as shown by the space 19.
Med andre ord vil en lodret forskydning af transportrulleme 2, 2a, 2b i for-10 hold til transportrulleme 1, 1a, 1b og 1c betyde, at den korteste afstand mellem nabotransportrulleme vil forøges.In other words, a vertical displacement of the transport rollers 2, 2a, 2b relative to the transport rollers 1, 1a, 1b and 1c will mean that the shortest distance between the neighboring transport rollers will be increased.
På figurerne 2-4 genfindes transportrulleme 1, 1a, 1b, 1c, 2, 2a, 2b samt flere (kun vist på fig. 2) tilsvarende transportruller.In Figures 2-4, the transport rollers 1, 1a, 1b, 1c, 2, 2a, 2b and several (only shown in Figure 2) are found transport rolls.
1515
Som det ses, er transportrullerne forbundet til en kæde, der er sammensat af par af kædeled 13a, 13b. Parrene af kædeled 13a, 13b er sammensat ved hjælp af gennemgående aksler 18, der også bærer transportrulleme 1, 1a, 1b, 1c samt afstandsstykker, der her er vist som hjul 14. For enden af 20 akslerne 18 er der monteret drivhjul, hvoraf et er betegnet med 11.As can be seen, the transport rollers are connected to a chain composed of pairs of chain links 13a, 13b. The pairs of chain links 13a, 13b are assembled by means of through shafts 18 which also carry the transport rollers 1, 1a, 1b, 1c as well as spacers shown here as wheels 14. At the end of the 20 shafts 18 are driven wheels, of which a is denoted by 11.
Som det yderligere ses, er der i de enkelte kædeled anordnet udsparinger 17, gennem hvilke der forløber aksler 15, som bærer transportrullerne 2, 2a og 2b, samt bøsninger 16, der fungerer som styr i udsparingerne 17. For 25 enden af akslerne 15 er der anordnet drivhjul, hvoraf et er betegnet med 12.As can be further seen, recesses 17 are provided in the individual chain links through which shafts 15 are supported which carry the transport rollers 2, 2a and 2b, as well as bushings 16 which act as guides in the recesses 17. At the 25 end of the shafts 15 arranged drive wheels, one of which is designated 12.
Som det ses, kan drivhjulene 11 på akslerne 18 have en mindre diameter end drivhjulene 12 på akslerne 15. Desuden ses det, at drivhjulene 12 med 30 den største diameter rager aksialt længere ud fra kædeleddene 13a, 13b end drivhjulene 11 med den mindste diameter. Drivhjulene tilvejebringes en horisontalbevægelse, f.eks. af ikke viste friktionsbånd, som der i forbindelse med de viste opstillinger på figurerne er to af. Drivbåndene kan ved hjælp 6 DK 174863 B1 af ikke viste motorer bringes til at rotere grupperne af transportruller med hver sin hastighed og med hver sin omløbsretning. Endelig er der til kæden med kædeleddene 13a, 13b forbundet en motor, således at kæden kan bevæges i retningen vist ved pilen 18 på fig. 1.As can be seen, the drive wheels 11 on the shafts 18 may have a smaller diameter than the drive wheels 12 on the shafts 15. Furthermore, it is seen that the drive wheels 12 of greatest diameter extend axially further from the chain links 13a, 13b than the drive wheels 11 of the smallest diameter. The drive wheels provide a horizontal movement, e.g. of friction bands not shown, of which there are two in connection with the shown arrangements in the figures. The drive belts can be caused to rotate the groups of conveyor rollers at different speeds and with each direction of rotation by means of motors not shown. Finally, a motor is connected to the chain by the chain links 13a, 13b, so that the chain can be moved in the direction shown by arrow 18 in FIG. First
5 r Funktionen af sorteringsanlægget skal herefter forklares.5 r The function of the sorting system must then be explained.
Fra en ikke vist beholder ledes der emner, f.eks. skaldyr, såsom rejer, ind på transportbåndet fra venstre på fig. 1.From a container not shown, items are fed, e.g. shellfish, such as shrimp, into the conveyor belt from the left in FIG. First
1010
Med henblik på at sortere rejerne i flere portioner efter størrelse hæves transportrullerne 2, 2a, 2b ved, at akslen 15 med bøsningen 16 og drivhjulene 12 hæves af det ikke viste drivbånd, der driver drivhjulene 12. Herved vil afstanden 19 mellem nabotransportruller, f.eks. 2b og 1c, blive forøget, 15 således at den maksimale størrelse af rejer, der ønskes frasorteret, falder gennem spalten 19.In order to sort the shrimp into several portions by size, the transport rollers 2, 2a, 2b are raised by raising the shaft 15 with the bushing 16 and the drive wheels 12 by the not shown drive belt driving the drive wheels 12. Thus, the distance 19 between neighboring transport rollers, f. eg. 2b and 1c, are increased, 15 so that the maximum size of shrimp to be cut off falls through the slot 19.
Samtidig tilvejebringes de enkelte drivhjul en passende rotationshastighed, der kan være indstillet således, at grupperne af transportruller roterer med 20 samme retning eller med modsatte retninger og med samme eller forskellige hastigheder. Desuden sættes kæden i bevægelse i horisontal retning af den ligeledes ikke viste drivenhed.At the same time, the individual drive wheels are provided with a suitable rotational speed which may be set such that the groups of transport rollers rotate in the same direction or in opposite directions and at the same or different speeds. In addition, the chain is moved in a horizontal direction by the drive unit not shown as well.
På denne måde vil emner, såsom rejer, der er for store til at passere i 25 spalterne 19, fikseres på transportrullerne uden at blive ødelagt ved klem- f ning i spalterne.In this way, items such as shrimp too large to pass through the slots 19 will be fixed to the transport rollers without being damaged by clamping in the slots.
Med henblik på at sortere skaldyr i flere størrelser kan sorteringsanlægget opbygges af flere sorteringsafsnit, således at det første sorteringsafsnit er 30 indstillet med den mindste spalte, medens det sidste afsnit er indstillet med den største spalte. I et sådant opbygget sorteringsanlæg vil de største emner, såsom rejer, blive sorteret i det sidste afsnit, da de naturligvis ikke kan passere de foregående afsnits spalter.In order to sort seafood into several sizes, the sorting system can be built up by several sorting sections, so that the first sorting section is set with the smallest column, while the last section is set with the largest column. In such a built-in sorting plant, the largest items, such as shrimp, will be sorted in the last section, as they obviously cannot pass through the slots of the previous paragraph.
