Den foreliggende opfindelse angår en liste til længdeforskydelig montage i et cylinderspor for brug ved et slibe- eller pudseværktøj, hvor cylindersporet har et radiært udefter tilspidsede tværsnitsform, hvor listens tværsnitsform modsvarer cylindersporets tværsnitsform, hvor listens tværsnitsform omfatter en øvre side og et antal sider, og 5 hvor der i listen er fastholdt et antal børster, som udgår fra listens øvre side.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame for longitudinally displaceable mounting in a barrel track for use with a grinding or polishing tool, wherein the barrel groove has a radially outwardly tapered cross-sectional shape, the cross-sectional shape of the bar corresponds to the cross-sectional shape of the bar, 5 where a number of brushes are retained from the top of the molding.
Ved overfladebehandling, som for eksempel slibning eller pudsning, af diverse elementer anvendes der slibe- og pudseværktøjer, der er udformet med et cylinderhoved, hvori der er monteret lister med slibepapir, lister med støttebørster, lister med mod-10 holdsbørster og diverse børstetyper.For surface treatment, such as grinding or polishing, of various elements, grinding and polishing tools designed with a cylinder head are used in which are grinding paper strips, support brush strips, mold brushes and various brush types.
Typisk er disse børster og slibepapir samlet i én liste, hvor listen er fremstillet i et plastmaterialet, og hvormed slibepapir og børster ofte er istøbt. Erfaringer viser, at slibepapir og støttebørster/modholdsbørster ikke slides lige hurtigt. Det medfører spild 15 af materiale, da det er nødvendigt at kassere hele listen ved en udskiftning, selvom det kun er slibepapiret der er nedslidt.Typically, these brushes and abrasive paper are grouped together into one molding, where the molding is made of a plastic material and with which abrasive paper and brushes are often cast. Experience shows that abrasive paper and support brushes / abrasion brushes do not wear out as quickly. This results in waste 15 of material, as it is necessary to discard the entire list at a replacement, even if only the abrasive paper is worn.
Da der på et cylinderhoved gennemsnitlig er mellem 30 og 60 lister med slibepapir og børster, der ved industriel brug af slibe- eller pudseværktøjet skal udskiftes jævnligt, 20 er der et problem med den mængde af lister og børster, der smides væk.Since, on a cylinder head, there are on average between 30 and 60 strips of abrasive paper and brushes that need to be replaced regularly in industrial use of the abrasive or cleaning tool, 20 there is a problem with the amount of strips and brushes thrown away.
Det er derfor formålet med opfindelsen at tilvejebringe en liste, der monteres længdeforskydeligt i et cylinderspor, hvor det er muligt at udskifte slibepapiret i listen, og hvor denne udskiftning af slibepapiret foretages nemt og hurtigt.It is, therefore, an object of the invention to provide a list which is slidably mounted in a cylinder groove where it is possible to replace the abrasive paper in the molding and where this replacement of the abrasive paper is made easily and quickly.

Dette opnås med en klemliste, der er kendetegnet ved, at listen omfatter et listespor til ί ' optagelse af et slibepapir, og hvor listesporet løber fra den øvre side af listen og ind i listen.This is achieved with a clamping strip, characterized in that the strip comprises a strip groove for the recording of an abrasive paper, and the strip groove runs from the upper side of the strip into the strip.
30 I det efterfølgende er der beskrevet en liste, der anvendes i forbindelse med et slibeeller pudseværktøj til overfladebehandling, men opfindelsen kan også anvendes i for- 2 DK 175953 B1 bindelse med andre værktøjer, hvor man ønsker at kunne udskifte en del af værktøjet, som for eksempel: - bladet på en isskraber, - bladet på en vinduesvisker, 5 - gummiet på en skraber, - kostene på en fejemaskine, og lignende.In the following, a list is used which is used in connection with a grinding or sanding tool for surface treatment, but the invention can also be used in connection with other tools where one wishes to be able to replace a part of the tool which for example: - the blade of an ice scraper, - the blade of a wiper, 5 - the rubber of a scraper, - the brushes of a sweeper, and the like.
For at kunne foretage en nem og hurtig udskiftning af sandpapiret i en liste og derved genbruge listen og de istøbte børster er der ifølge opfindelsen frembragt en liste til 10 længdeforskydelig montage i et cylinderspor for brug ved et slibe- eller pudseværktøj, hvor cylindersporet har et radiært ud efter tilspidsede tværsnitsform, hvor listens tværsnitsform modsvarer cylindersporets tværsnitsform, hvor listens tværsnitsform omfatter en øvre side og et antal sider, og hvor der i listen er fastholdt et antal børster, som udgår fra listens øvre side, hvor listen omfatter et listespor til optagelse af et slibepapir 15 og hvor listesporet løber fra den øvre side af listen og ind i listen.In order to be able to easily and quickly replace the sandpaper in a molding and thereby recycle the molding and the molded brushes, the invention provides a molding for 10 length-displaceable mounting in a cylinder groove for use with a grinding or cleaning tool, the cylinder groove having a radial according to tapered cross-sectional shape, where the cross-sectional shape of the mold corresponds to the cross-sectional shape of the cylinder groove, where the cross-sectional shape of the molding comprises an upper side and a number of sides, and where a number of brushes starting from the upper side of the molding are maintained in the molding, the list comprising a molding groove for recording a grinding paper 15 and wherein the molding groove runs from the upper side of the molding into the molding.
I denne udførelsesform af listen er det muligt, at fastgøre et slibepapir til listen ved simpelthen at placere en del af slibepapiret ned i listesporet, hvorefter en sammenfø-relseskraft vil presse listesporets sider sammen og derved klemme omkring slibepapi-20 ret og fastholde det til listen.In this embodiment of the list, it is possible to attach a abrasive to the list by simply placing a portion of the abrasive paper down the list track, after which an interlocking force will compress the sides of the list track, thereby clamping around the abrasive paper and holding it to the list. .
For at opnå en optagelse af slibepapiret i listesporet og samtidig opnå en sikkerhed for at slibepapiret fastholdes til listen, er listesporet udformet af én eller flere dele, hvor den første del er et fortrinsvis lige spor, og hvor listesporet er udformet af én eller flere 25 dele, hvor den anden del omfatter enten en hulkel eller et fortrinsvis lige spor, der er forbundet i en vinkel i forhold til den første del af listens langsgående spor.In order to obtain an abrasion of the abrasive paper in the groove groove and at the same time obtain a guarantee that the abrasive paper is retained to the groove, the groove groove is formed of one or more parts, the first part being a preferably straight groove and the groove groove being formed by one or more grooves. portions, the second portion comprising either a hollow or a preferably straight groove connected at an angle to the first portion of the longitudinal groove of the strip.
I en første udførelsesform består listesporet af et fortrinsvis lige spor, hvor slibepapiret placeres således at slibepapiret udfylder en væsentlig del af slibesporet, hvorefter en 30 sammenførelseskraft vil presse listesporets sider samme og derved klemme omkring slibepapiret og fastholde det til listen.In a first embodiment, the strip groove consists of a preferably straight groove, where the abrasive paper is positioned so that the abrasive paper fills a substantial portion of the abrasive groove, after which a jointing force will press the sides of the strip groove the same, thereby clamping around the abrasive paper and holding it to the strip.
3 DK 175953 B1 I en anden udførelsesform, består listesporet af en første del, der er et lige stykke og en anden del, der er en hulkel, hvor slibepapiret placeres således, at slibepapirets nedre del strækker sig igennem listesporets første del og ned i hulkelen. Det betyder, at slibepapirets nedre del kan oprulles, således at denne oprulningen passer til hulkelens 5 størrelse. Denne fortykkelse af tværsnittet af slibepapirets nedre del medfører, at slibepapirets nedre del har et større tværsnit end bredden af listesporets første del. Det betyder, at slibepapiret bliver fastholdt i listesporet under såvel driftssituation som hvilesituation.In another embodiment, the molding groove consists of a first portion which is a straight piece and a second portion which is a hollow where the abrasive paper is placed such that the lower portion of the abrasive paper extends through the first portion of the molding groove and down into the hollow . This means that the lower part of the abrasive paper can be rolled up to fit the size of the hollow 5. This thickening of the cross-section of the lower part of the abrasive paper causes the lower part of the abrasive paper to have a larger cross-section than the width of the first part of the molding groove. This means that the abrasive paper is retained in the molding groove during both operating and resting situations.
10 I en tredje udførelsesform, består listesporet af en første del, der er et lige stykke og en anden del, der er er et lige stykke, og som er indbyrdes forbundet i en vinkel. Slibepapiret placeres således, at slibepapirets nedre del strækker sig igennem listesporets første del og ind i listesporets anden del. Ombukningen af slibepapirets nedre del ved overgangen fra listesporets første delt og listesporets anden del gør at slibepapiret bli-15 ver fastholdt i listesporet under såvel driftssituation som hvilesituation.In a third embodiment, the molding groove consists of a first portion which is a straight portion and a second portion which is a straight portion and which are interconnected at an angle. The abrasive paper is positioned so that the lower portion of the abrasive paper extends through the first portion of the molding groove and into the second portion of the molding groove. The folding of the lower part of the abrasive paper at the transition from the first part of the molding groove and the second part of the molding groove causes the abrasive paper to be retained in the molding groove during both operating and resting situations.
Da det er selv ombukningen af slibepapiret, der anvendes som modhold og omkostningen til slibepapir er minimal, er det ikke nødvendigt, at slibepapiret strækker sig helt ind i bunden af det listesporets anden del.Since it is even the bending of the abrasive paper that is used as a restraint and the cost of abrasive paper is minimal, it is not necessary for the abrasive paper to extend completely into the bottom of the second part of the molding groove.
2020
Uanset hvilken af de ovennævnte udførelsesformer af listen der anvendes er det vigtigt, at slibepapiret fastholdes i listesporet ved hjælp af en sammenførelseskraft, der virker på en del af slibesporets første del. Denne sammenførelseskraft skal opfattes som en tangentiel kraft, der bringer en del af siderne af listesporets første del sammen, 25 og som opnås enten mekanisk eller ved hjælp af centrifugalkraften.Regardless of which of the above embodiments of the moldings used, it is important that the abrasive paper be retained in the molding groove by means of a joining force acting on a portion of the first portion of the abrasive groove. This joining force is to be construed as a tangential force which brings together a portion of the sides of the first portion of the groove groove, 25 which is obtained either mechanically or by the centrifugal force.
På grund af cylindersporets radiært udefter tilspidsede tværsnitsform og listens modsvarende form vil et radialt udefter rettet tryk på listen medføre, at listen klemmes fast i cylindersporet og sammenførelseskraften opstår på en del af listesporets første del.Due to the radially outwardly tapered cross-sectional shape of the cylinder groove and the corresponding shape of the molding, a radially outwardly directed pressure on the molding will cause the molding to be clamped in the cylinder groove and the compressive force arises on part of the first part of the molding groove.
30 4 DK 175953 B1 [ en udføreisesform er udmundingen af listesporets første del på listens øvre side placeret tæt ved kanten af den øvre side. Slibepapiret er således placeret i den ene side af listen og der er derfor efterfølgende plads til et antal børster på den øvre side.30 4 DK 175953 B1 [In an embodiment, the opening of the first part of the molding groove on the upper side of the molding is located close to the edge of the upper side. The abrasive paper is thus placed on one side of the list and there is therefore room for a number of brushes on the upper side.
5 I en den udførelsesform, hvor listesporet består af en første del, der er et lige stykke og en anden del, der er er et lige stykke, og som er indbyrdes forbundet i en vinkel, vil der frembringes en flig, der består af en af listen ydresider og en del af listen bund.In one embodiment in which the groove groove consists of a first portion which is a straight portion and a second portion which is a straight portion and which are interconnected at an angle, a tab consisting of a of the outer pages list and part of the bottom list.
Denne flig vil have et omdrejningspunkt i bunden af listesporets andel, og derfor vil der være en haengselseffekt, der gør det nem og hurtigt at montere/udskifte slibepapi-10 ret.This tab will have a pivot point at the bottom of the groove section and therefore there will be a hinge effect that makes it easy and fast to install / replace the grinding paper.
1 en udførelsesform af opfindelse hvor sammenførelseskraften frembringes mekanisk er listen og cylindersporet udformet således, at listen ved montage i cylinderhovedets spor monteres med en fjederplade, hvor fjederpladen er monteret i bunden af cylinder-15 hovedet spor, hvor fjederpladen i en aktiv position udøver et radialt ud efter rettet tryk på listen, hvorved der opstår en sammenførelseskraft på i det mindste listesporets første del.In an embodiment of the invention where the actuating force is produced mechanically, the strip and the cylinder groove are designed so that, when mounted in the cylinder head groove, the strip is mounted with a spring plate, the spring plate being mounted at the bottom of the cylinder head groove, where the spring plate in an active position exerts a radial out after directed pressure on the list, resulting in a joining force of at least the first part of the list track.
Fjederpladen består af en øvre del og en nedre del som kan forskydes i forhold til hin-20 anden. Fjederpladen øvre og nedre del er begge forsynet med et antal forhøjninger.The spring plate consists of an upper part and a lower part which can be displaced relative to the other. The spring plate upper and lower part are both provided with a number of elevations.
Denne fjerderplade har to positioner, der opnås ved en side forskydning af enten den øvre del og/eller den nedre del: - en aktiv position hvor fjederpladens øvre og nedre del er bragt i en position hvor de 25 to deles forhøjninger er placeret udfor hinanden, hvorved fjederpladen højde øges og presser listen radialt udefter.This spring plate has two positions which are obtained by a side displacement of either the upper part and / or the lower part: - an active position in which the upper and lower part of the spring plate are placed in a position where the elevations of the two parts are placed next to each other, thereby increasing the height of the spring plate and pressing the list radially outwards.
- en passiv position, hvor fjederpladens øvre og nedre del er bragt i en position hvor de to deles forhøjninger er placeret forskudt for hinanden, hvorved tjederpladen højde reduceres og den radialt udefterrettede kraft reduceres. I denne position er det muligt 30 at længdeforskyde og fjerne listen fra cylindersporet for udskiftning af slibepapiret.- a passive position where the upper and lower parts of the spring plate are placed in a position where the elevations of the two parts are offset to one another, thereby reducing the height of the spring plate and reducing the radially outward force. In this position, it is possible to longitudinally displace and remove the strip from the cylinder groove for replacing the abrasive paper.
5 DK 175953 B1 I en anden udførelsesform af opfindelse hvor sammenførelseskraften frembringes mekanisk er listen og cylindersporet udformet således at listen har et lille overmål i forhold til cylindersporet. Det gør at sammenførelseskraften opstår ved montage af listen i cylindersporet og holdes i al den tid listen er monteret i cylindersporet. Det medfører 5 dag at der skal bruges en vis kraft for montage og demontage af listen i cylindersporet.In another embodiment of the invention where the compressive force is generated mechanically, the molding and the cylinder groove are designed so that the molding has a small oversize relative to the cylinder groove. This causes the joining force to occur when mounting the frame in the cylinder groove and is kept for all the time the frame is mounted in the cylinder groove. This means that 5 days a certain amount of force must be used to assemble and disassemble the moldings in the cylinder groove.
Det er dog en ulempe hvis listen er fremstillet af et blødt materiale, da det kan være vanskeligt at montere en blød liste med et overmål.However, it is a disadvantage if the list is made of a soft material, as it can be difficult to assemble a soft list with an overlay.
I en tredje udførelsesform af opfindelse, hvor sammenførelseskraften frembringes me-10 kanisk, er listen og cylindersporet udformet således, at der i bunden af hvert cylinderspor enten over hele sporets længde eller på dele af sporet er placeret en excentrisk enhed, der ved drejning af en møtrik eller en skrue sørger for, at der udøves et radialt udefterrettet tryk på listen.In a third embodiment of the invention, in which the joining force is mechanically produced, the molding and the cylinder groove are formed such that an eccentric unit is placed at the bottom of each cylinder groove either over the entire length of the groove or on parts of the groove. nut or screw ensures that a radially outward pressure is exerted on the list.
15 Denne excentriske enhed kan for eksempel enten være tilkoblet en udløser-enhed for hver cylinderspor eller være tilkoblet én samlet udløser, således at denne udløser eller udløser alle de excentriske enheder i cylinderhovedets cylinderspor.This eccentric unit may, for example, either be coupled to a trigger unit for each cylinder groove or be coupled to a single trigger, so that it releases or releases all the eccentric units in the cylinder head's cylinder groove.
I en udførelsesform af opfindelse, hvor sammenførelseskraften frembringes ved hjælp 20 af centrifugalkraften, er listen og cylindersporet udformet således listen og cylinder-sporet har en tværsnitsform, der direkte modsvarer hinanden. Under drift vil centrifugalkraften udøve en radial ud efter rettet kraft, der medfører at listen sammenpresses i cylindersporet, og der opstår en sammenførelseskraft på en del af listesporets første del, der klemmer sammen og fastholder slibepapiret. Denne metode til frembringelse 25 af sammenførelseskraften kan kun benyttes i de udførelsesformer af listen, hvor listesporet tillader enten en sammenrulning af den nedre del af slibepapiret i en hulkel eller en ombukning af den nedre del af slibe papiret der er placeret i listesporets anden del.In one embodiment of the invention, in which the compressive force is generated by the centrifugal force, the strip and the cylinder groove are thus formed and the cylinder groove has a cross-sectional shape which directly corresponds to one another. In operation, the centrifugal force exerts a radial after directed force which causes the molding to be compressed in the cylinder groove and a joining force is formed on a portion of the first part of the molding groove which clamps together and holds the abrasive paper. This method of generating the compression force can only be used in those embodiments of the molding wherein the molding groove allows either a roll-down of the lower portion of the abrasive paper into a hollow or a folding of the lower portion of the abrasive paper located in the second portion of the molding groove.
For at kunne opnå en sammenførelseskraft er listen udformet således, at listen er frem-30 stillet enten i et ekstruderet termoplastisk materiale eller i en støbt og/eller ekstruderet metallegering. Disse materialer skal have en vis fleksibilitet og elasticitet, for at materialet vil tillade en deformering uden at gå i stykker.In order to achieve a joining force, the molding is formed such that the molding is made either in an extruded thermoplastic material or in a cast and / or extruded metal alloy. These materials must have some flexibility and elasticity in order for the material to allow deformation without breaking.

Ved ekstrudering af en liste i følge opfindelsen vil der opnås en yderligere fordel, da materiale sugning ved ekstrudering af en liste undgås. Materialesugning forekommer, når der fremstilles elementer af med flader af en vis størrelse, da afkølingen af elemen-5 tet medfører at siderne blive konkave. Dette kan være en ulempe ved fremstilling af lister i følge opfindelsen, da den uønskede form frembragt af materiale sugning kan medføre, at listen ikke kan fastholdes i cylindersporet. Endvidere vil frembringelsen af listespor i listen medføre en reduktion af materialeforbruget og reducere risikoen for materiale sugning.In extrusion of a molding according to the invention, an additional advantage will be obtained since material suction by extrusion of moldings is avoided. Material suction occurs when elements of surfaces of a certain size are made, as the cooling of the element causes the sides to become concave. This can be a disadvantage in the manufacture of moldings according to the invention, since the undesirable shape produced by material suction can cause the mold to not be retained in the cylinder groove. Furthermore, the production of moldings in the moldings will reduce the material consumption and reduce the risk of material suction.
10 I en udførelsesform af listen er listen udformet af én eller flere rækker børster, fortrinsvis 2-4 rækker, hvor rækkerne er indbyrdes forskudt. Denne udformning af listen medfører, at listen kan fremstilles i en mindre dimension, da række forskydningen af børsterne medfører, at der kan placeres flere rækker børster på samme areal end ved 15 almindelige sidestillede børsterækker. Antallet af børster har endvidere betydning for, hvor god en slibning/pudsning slibepapiret foretager.In one embodiment of the list, the list is formed of one or more rows of brushes, preferably 2-4 rows, the rows being offset. This design of the list means that the list can be made in a smaller dimension, as the series of brush displacements means that more rows of brushes can be placed in the same area than with 15 ordinary parallel brush rows. The number of brushes also has a bearing on how good a grinding / polishing sandpaper is.
I anden udførelsesform af listen kan listesporet være udformet til optagelse af slibepapir og et antal børster. For at øge effektiviteten af slibepapiret kan der i forbindelse 20 med slibepapiret være monteret et antal støttebørster i samme listespor. Det sikrer en nær/god kontakt mellem slibepapir og første række børster. Det betyder dog, at listesporet skal være bredere, end hvis det kun er slibepapiret der skal fastholdes, og at der højst sandsynligt skal frembringes en større sammenførelseskraft for at fastholde slibepapir og et antal børster.In the second embodiment of the molding, the molding groove may be designed for receiving abrasive paper and a number of brushes. In order to increase the efficiency of the abrasive paper, in connection with the abrasive paper, a number of support brushes may be mounted in the same molding groove. This ensures close / good contact between abrasive paper and first line of brushes. However, this means that the molding groove must be wider than if only the abrasive paper is to be retained and that a greater joining force is likely to be produced to retain abrasive paper and a number of brushes.
