Opfindelsen angår slidplader med indsatte elementer til indikation af en forud givet slidtilstand til anlæg og/eller maskiner til skrot-, storskralds- eller affaldsbearbejdning, såsom skrotsakse men også i bredere henseende beklædninger af maskinfundamenter.The invention relates to wear plates with inserted elements for indicating a predetermined wear condition for plants and / or machines for scrap, large rubbish or waste processing, such as scrap shears, but also in broader coatings of machine foundations.
5 Der kendes almindelige tekniske forholdsregler inden for maskin- eller aniægsdiagnosen til konstatering og analyse af maskiners slidtilstand.5 General technical precautions are known in the field of machine or face diagnostics for determining and analyzing the wear condition of machines.
Inden for motorkøretøjsområdet er det kendt ved hjælp af kontaktelementer elektrisk at konstatere og indikere slidtilstanden af brem-10 sebelægninger, når der nås en restbelægning.Within the motor vehicle area, it is known to electrically detect and indicate the wear state of brake linings by means of contact elements when a residual coating is reached.
Fra DD 301 241 A7 kendes der indretninger til visning af grænseværdien for et slagpladeslid på slaghjul. At indsætte sådanne elementer på den ikke for slid udsatte bagside af en plade, der slides, kan udledes af EP 0 411 284 A2 for bremsebelægninger. Derved kunne fag-15 manden realisere en nærliggende sammensætning, der dog i henseende af de indledningsvist nævnte anlæg stadig ville udvise ulemper.From DD 301 241 A7 devices are known for displaying the limit value for an impact plate wear on impact wheels. Inserting such elements on the non-abrasive back of a wear plate can be deduced from EP 0 411 284 A2 for brake linings. In doing so, the skilled artisan was able to realize a nearby composition which, however, with respect to the plants mentioned above, would still exhibit disadvantages.
Således skal det, eksempelvis på grund af bøjning eller brud på maskindele, sikres, at sådanne derpå anbragte slidplader med slidindikatorer fortsat fungerer ved disse anlæg og ved maskiner.Thus, for example due to bending or breaking of machine parts, it must be ensured that such wear plates with wear indicators continued to function at these systems and machines.
20 I denne forbindelse skal der henvises til DE-A-26 55 657 Al, der heller ikke løser problemet og ikke skaber udsigt til andre løsningstiltag, om end der ifølge "Handbuch, der industriellen Messtechnik", 5. oplag, 1992 allerede eksisterer muligheder til bestemmelse af pladers tykkelse.20 In this connection, reference should be made to DE-A-26 55 657 A1, which does not solve the problem and does not create prospects for other solutions, although according to "Handbuch, industrialen Messtechnik", 5th edition, 1992, opportunities already exist for determining the thickness of plates.
25 Ved anlæg eller maskiner til skrot-, storskralds- eller affaldsbe arbejdning er det et specifikt problem at udskifte de til beskyttelse af såvel grundkonstruktionen som de kraftoverførende maskinelementer udskifteligt indlagte slidplader eller slidblik i rette tid. Hyppigt konstaterer operatøren af anlægget eller maskinen ikke slidtilstanden af disse 30 maskinelementer i rette tid, eller slidtilstanden konstateres alt efter indbygningsstedet af det enkelte slidelement først, når foranliggende elementer demonteres, eller som førnævnt falder ud som følge af bøjning eller brud.25 In the case of plants or machines for scrap, large-scale or waste processing, it is a specific problem to replace the in-place wear plates or wear gauges in a timely manner to protect both the basic structure and the power-transferring machine elements. Frequently, the operator of the plant or machine does not detect the wear condition of these 30 machine elements in a timely manner, or the wear condition is determined according to the place of installation of the individual wear element only when the abovementioned elements are disassembled or, as aforesaid, falls out due to bending or breakage.
Således kan der, eksempelvis ved skrotsakse, på grund af for DK 176829 B1 2 sen konstatering af slidtilstanden af de elementgruppen af glideplader vedføjede slidplader, opstå betydelige skader i grundkonstruktionen og yderligere i det hydrauliske system, da den nødvendige glidende understøtning af bevægede maskinelementer på grund af det forøgede slid ik-5 ke mere er sikret. Da belastningen fra maskinelementerne så overføres til hydraulikcylinderens stempel, bøjer eller brækker stempelstangen, eller hydraulikcylinderen slides i det mindste kraftigt.Thus, for example with scissors, due to DK 176829 B1 2 late detection of the wear state of the element group of sliding plates attached wear plates, significant damage can occur in the basic structure and further in the hydraulic system, since the necessary sliding support of moving machine elements due to of the increased wear none more is ensured. Since the load from the machine elements is then transferred to the piston of the hydraulic cylinder, the piston rod bends or breaks, or the hydraulic cylinder is at least worn out.
En sammenfatning af de i den fremdragne kendte teknik forefundne træk og løsninger kan ikke i tilstrækkelig grad løse det forelig-10 gende problem.A summary of the features and solutions found in the prior art cannot adequately solve the present problem.
Den foreliggende opfindelse har til opgave med teknisk enkle midler at konstatere slidtilstanden af maskinelementer af den indledningsvis nævnte art og dermed at sikre eller at forøge funktionsdygtigheden og disponibiliteten af tilsvarende anlæg eller maskiner, idet der 15 skal tilvejebringes en fornuftig anvendelse af gennemprøvede enkelttræk i en samlet set ny konstruktion af slidplader med indsatte elementer til indikation af en forud given slidtilstand.The object of the present invention is to find, by technically simple means, the wear state of machine elements of the type mentioned in the introduction and thus to ensure or to increase the operation and availability of corresponding systems or machines, in order to provide a reasonable use of tested single features in an overall seen new construction of wear plates with inserted elements to indicate a predetermined wear condition.
Denne opgave løses ifølge opfindelsen ved trækkene i krav 1-7.This task is solved according to the invention by the features of claims 1-7.
Princippet i denne nye kombination af træk består af slidplader 20 med indsatte elementer til indikation af en forud givet slidtilstand til anlæg og/eller maskiner til skrot-, storskralds- eller affaldsbearbejdning, såsom skrotsakse, som er ejendommelig ved, a) at på hinanden glidende og korresponderende slidplader hver har mindst ét element til indikation af slidtilstanden, 25 b) at mindst ét element er indsat på den ikke for slid udsatte bagside af slidpladerne og er af et materiale, som højst er lige så hårdt som slidpladernes materiale, c) at et bestemt, maksimalt tilladeligt slid af slidpladerne tjener som mål for indsætningsdybden af det mindste ene element, hvilket mål 30 tillige udgør den nominelle tykkelse af det tilbageblivende restmateriale af slidpladerne, og d) at elementet, for en konstatering af den nåede nominelle tykkelse af det tilbageblivende restmateriale af slidpladerne, er enten optisk konstaterbar, frembringer et signal eller udgør en elektronisk DK 176829 B1 3 sensor.The principle of this new combination of features consists of wear plates 20 with inserted elements to indicate a predetermined abrasion condition for plants and / or machines for scrap, large rubbish or waste processing, such as scissors characterized by: (a) sliding on one another and corresponding wear plates each have at least one element for indicating the wear condition; b) at least one element is inserted on the non-wear back of the wear plates and is of a material which is at most as hard as the material of the wear plates; a certain maximum allowable wear of the wear plates serves as a measure of the insertion depth of the at least one element, which measure 30 also represents the nominal thickness of the remaining residual material of the wear plates, and d) that the element, for a determination of the nominal thickness reached residual material of the wear plates is either optically detectable, produces a signal or forms an electronic DK 176829 B1 3 sensor.
Opfindelsen vil i det følgende blive forklaret nærmere ved hjælp af udførelsesformer under henvisning til tegningen, på hvilken fig. 1 viser i udsnit en udførelsesform af korresponderende slid-5 elementer på glidepladen af en skrotsaks, fig. 2 et skematisk billede af en udførelsesform ifølge opfindelsen til konstatering af slidtilstanden ved hjælp af en infrarødindretning, og fig. 3 et forenklet billede af en yderligere udførelsesform af et 10 diagnosesystem.The invention will now be explained in more detail with the aid of embodiments with reference to the drawing, in which fig. 1 shows in section an embodiment of corresponding wear elements on the sliding plate of a scrap shaft; 2 is a schematic view of an embodiment of the invention for determining the wear state by means of an infrared device; and FIG. 3 is a simplified view of a further embodiment of a diagnostic system.
Fig. i viser i udsnittet Xl,2 slidelementer på en ikke nærmere forklaret skrotsaks. En glideplade i udfører en med pilene antydet slagbevægelse. Glidepladen i har som maskinelement en udskiftelig slidplade 1.1, som glider på et ligeledes som slidplade 2.1 udformet maskin-15 element på en ledeskinne 2 af skrotsaksen.FIG. in section Xl, 2 wear elements on an unexplained scissors are shown. A slide plate in performs a stroke motion indicated by the arrows. The slide plate i has as a machine element a replaceable wear plate 1.1 which slides on a machine element also formed as a wear plate 2.1 on a guide rail 2 of the scrap shaft.
Som vist i udsnittet XI, forefindes til indikation af slidtilstanden elementer 3, af hvilke det i slidpladen 1.1 indsatte element 3 har en af en elektrisk svagstrøm gennemløbet ledersløjfe som elektrisk kontaktsystem, og det i slidpladen 2.1 beliggende element 3 er indsat som en 20 prop i en boring i den for slid ikke-udsatte side af slidpladen 2.1 og har en optisk konstaterbar signalfarve. Når der nås en bestemt slidtilstand af slidpladen 1.1, som vist i udsnittet X2, udløses ved afbrydelse af kontakten et signal, som kan overføres, og som indikerer, at den slidte slidplade l.l. skal udskiftes. På ledeskinnen 2's side indikerer det som vist i 25 udsnit XI indsatte element 3 "fra oven" optisk konstaterbart den forudbestemte slidtilstand af slidpladen 2.1, hvorved indikeres at dette maskinelement skal udskiftes. Det sidstnævnte element 3 kan fortrinsvist være udført som f.eks. en signalfarvet formstofprop og være klæbet eller støbt ind i en boring i slidpladen 2.1's tilbageværende ikke for slid 30 udsatte Testmateriale.As shown in section XI, elements 3 are indicated for indication of the wear state, of which the element 3 inserted in the wear plate 1.1 has an conductor loop passed through an electrical low-current as an electrical contact system, and the element 3 located in the wear plate 2.1 is inserted as a plug. a bore in the non-exposed side of the wear plate 2.1 and has an optically detectable signal color. When a certain wear state is reached by the wear plate 1.1, as shown in section X2, by interrupting the contact a signal which can be transmitted, indicating that the worn wear plate l.l. must be replaced. On the side of the guide rail 2, as shown in section XI, element 3 inserted "from above" optically indicates the predetermined wear state of the wear plate 2.1, indicating that this machine element must be replaced. Preferably, the latter element 3 may be made e.g. a signal-stained plastic plug and be glued or molded into a bore in the wear plate 2.1's remaining non-wear Test Material.
Ovennævnte elementer 3 består af materiale, der i forhold til slidpladerne 1.1, 2.1's materiale er højst lige så hårdt, og er indsat fra de respektive ikke for slid udsatte bagsider af slidpladerne 1.1, 2.1.The aforementioned elements 3 consist of material which, in relation to the wear plates 1.1, 2.1, is at most equally hard, and is inserted from the respective non-wear backs of the wear plates 1.1, 2.1.
Derved tjener et bestemt, maksimalt tilladeligt slid af slidpladerne 1.1, 4 DK 176829 B1 2.1 som mål for indsætningsdybden af elementerne, hvilket mål tillige er den nominelle tykkelse af det tilbageblivende restmateriale af slidpladerne 1.1, 2.1 for opnåelse af en tilstrækkelig understøtning af stillingen og bevægelsen af maskindele, som ikke er forbundet direkte med slid-5 pladerne 1.1, 2.1.Thereby, a certain maximum permissible wear of the wear plates 1.1, 4 serves as a measure of the insertion depth of the elements, which measure is also the nominal thickness of the remaining residual material of the wear plates 1.1, 2.1 for obtaining sufficient support for the position and movement. of machine parts not directly connected to the wear plates 1.1, 2.1.
Derved løses det indledningsvis nævnte problem med skrotsakse, idet skader på grundkonstruktionen og yderligere i det hydrauliske system kan undgås, fordi den nødvendige glidende understøtning af de bevægede maskindele er sikret tilstrækkeligt og ikke på grund af for 10 stort slid er udsat for fare.This solves the problem of scissors initially mentioned, since damage to the basic structure and further in the hydraulic system can be avoided because the necessary sliding support of the moving machine parts is sufficiently secured and is not exposed to danger due to excessive wear.
Hertil kommer, at i horisontal retning virkende drivaggregater, såsom hydraulikcylindere med stempel og stempelstang, i stor udstrækning aflastes for den af sliddet betingede maskindelslast, som fremkalder en bøjepåvirkning. Derved tilvejebringer slidpladerne 1.1, 15 2.1 ifølge opfindelsen en sikker måde, hvorpå f.eks. skrotsakse kan dri ves.In addition, horizontal actuators, such as piston and piston rod hydraulic cylinders, are relieved to a large extent for the wear-dependent machine part load, which produces a bending effect. Thereby, the wear plates 1.1, 2.1 of the invention provide a safe way in which e.g. scissors can be dried.
I fig. 2 er opfindelsens grundtanke vist på forenklet måde i forbindelse med konstatering af en forudbestemt slidtilstand af et med slidpladen 1.1 sammenligneligt slidelement, ved hjælp afen infrarødind-20 retning 4.In FIG. 2, the basic idea of the invention is shown in a simplified manner in connection with the finding of a predetermined wear state of a wear element comparable to the wear plate 1.1, by means of an infrared device 4.
Ved hjælp af kombinationen, som i fig. 3 er skematisk vist, kan tilvejebringes et effektivt diagnosesystem til forøgelse af disponibiliteten af anlæg eller maskiner for det indledningsvis beskrevne anvendelsesområde, når der på anlægget/maskinen på for slid udsatte steder på 25 maskinelementer 1, såsom slidplader 1.1, 2.1, anbringes sensorer, som fungerer som elementerne 3 ifølge opfindelsen. Via en EDB-støttet analyseindretning 5 synliggøres slidtilstandene analogt eller digitalt i en udlæsningsindretning 6 og gøres endog over et fjernaflæsningsmodul 7 kontrollerbare. Denne indretning muliggør en permanent konstatering af 30 de respektive slidtilstande, hvorved der ved hjælp af sensorerne, som kontinuerligt afgiver signaler, fås et forvarsel om opnåelse af et bestemt fremskridt af sliddet. Samtidig kan signaloverførslen ske via ledninger eller radiokommunikation.By means of the combination shown in FIG. 3 is schematically shown, an effective diagnostic system can be provided to increase the availability of systems or machines for the initially described application when sensors placed on the plant / machine at locations exposed to wear on 25 machine elements 1 such as wear plates 1.1, 2.1 functions as the elements 3 according to the invention. Via a computer-aided analysis device 5, the wear states are visualized analogously or digitally in a readout device 6 and even made controllable via a remote reading module 7. This device permits a permanent detection of the respective wear states, whereby by means of the sensors which continuously emit signals, a warning is obtained of obtaining a certain progress of the wear. At the same time, signal transmission can take place via wires or radio communication.
