Omfang af opfindelsenScope of the Invention

Den foreliggende opfindelse angår et slibeapparat til behandling af et emne omfattende et antal slibcelemcnter, et antal slibemotorer og et bærearrangement med et antal bevægemotorer, hvor nævnte slibeelementer er drevet af nævnte slibemotorer og udgør et antal af slibehoveder, som er forbundet med nævnte bærearrangement, hvor hvert slibehoved omfatter et slibeelement med tilhørende slibemotor.The present invention relates to a grinding apparatus for treating a workpiece comprising a plurality of grinding elements, a plurality of grinding motors and a bearing arrangement having a plurality of moving motors, said grinding elements being driven by said grinding motors and constituting a plurality of grinding heads connected to said support arrangement, wherein each grinding head comprises a grinding element with associated grinding motor.

Baggrund for opfindelsenBACKGROUND OF THE INVENTION

Ved industriel slibning af emner, der omfatter kanter, rundinger og flader, for eksempel bordplader, anvendes der forskellige type slibeapparater, der kan slibe hele emnet ved et gennemløb igennem slibeapparatet. For at opnå en pæn overflade er det vigtigt, at slibeapparatet ikke efterlader tydelige mærker efter sliberetningen.In industrial grinding of items comprising edges, rounds and surfaces, for example countertops, various types of grinding devices are used which can grind the entire workpiece as a passage through the grinder. In order to achieve a nice surface, it is important that the grinder does not leave clear marks after the grinding direction.

Der findes for eksempel slibeapparater med et antal valser enten med omsluttende slibepapir eller med et antal slibeelementer, som er placeret langs valsens længderet-ning.For example, abrasives are provided with a plurality of rollers either with wrapping abrasive paper or with a plurality of abrasive elements located along the longitudinal direction of the roll.

For at undgå at sliberetningen af valserne er ens er slibeapparatet udformet med enten valser, der typisk roterer modsat af hinanden eller valser, der er indstillet med forskellige vinkler i forhold til fladen.To prevent the grinding direction of the rollers from being the same, the grinding apparatus is formed with either rollers which typically rotate opposite each other or rollers which are set at different angles to the surface.

Ulempen ved disse typer valser er, at de bruger en stor mængde slibepapir, hvorved slibepapiret tit skal udskiftes. Dette medfører produktionsstop og øger omkostningerne til slibning.The disadvantage of these types of rollers is that they use a large amount of abrasive paper, whereby the abrasive paper often has to be replaced. This results in production stoppages and increases the cost of grinding.

Endvidere vil slibepapiret ikke blive slidt ens hen langs valsen, specielt ikke hvis der skal slibes emner med forskellige dimensioner. Slibepapiret vil typisk blive slidt mest på den midterste del af valsen.Furthermore, the abrasive paper will not be worn evenly along the roller, especially if items of different dimensions are to be sanded. The abrasive paper will typically be worn most on the middle part of the roller.

I WO99/22905 og ΕΡ0 471 641 er der beskrevet en anden type slibeapparat, hvor et antal roterende valser er placeret omkring en lodret aksel, der er forbundet til en drivenhed, således at valserne, udover at rotere om deres egen aksel, roterer i det vandrette plan omkring den lodrette aksel.In WO99 / 22905 and 470 471 641 another type of grinding machine is described, in which a plurality of rotating rollers are placed around a vertical shaft connected to a drive unit, so that, in addition to rotating about their own shaft, the rollers rotate therein. horizontal plane around the vertical shaft.

2 DK 2005 00267 U32 DK 2005 00267 U3

Ved at rotere valsen omkring to aksler prøver man at undgå tydelige slibemærker. I WO99/22905 roterer valserne indbyrdes i forskellig retning med forskellige hastigheder.By rotating the roller around two shafts you try to avoid clear abrasions. In WO99 / 22905 the rollers rotate in different directions at different speeds.

Ulempen ved dette er, at de roterende valser med omløbsretning modsat af rotationen i det vandrette plan vil have en større slibende effekt end de valser, der har omløbsretning i samme retning som rotationen i det vandrette plan.The disadvantage of this is that the rotating rollers with the direction of rotation opposite to the rotation in the horizontal plane will have a greater abrasive effect than the rollers having the direction of rotation in the same direction as the rotation in the horizontal plane.

I ΕΡ0 471 641 anvendes et antal slibearrangementer, hvor hvert slibearrangement består af et antal roterende valser, der roterer omkring en lodret aksel. For at sikre slibning af hele emnet er disse slibearrangementer arrangeret med overlap, hvilket medfører en ujævn slibning, da der er områder af emnet, som slibes mere end en gang.In 470 471 641, a number of grinding arrangements are used, each grinding arrangement consisting of a number of rotating rollers rotating about a vertical shaft. To ensure grinding of the entire workpiece, these grinding arrangements are arranged with overlap, which causes an uneven grinding as there are areas of the workpiece that are sanded more than once.

Ulempen ved begge ovennævnte slibeapparater er, at de for at kunne slibe brede emner skal have lange valser, hvilket medfører, at motorenhedeme til disse valser skal være tilsvarende større. Det resulterer i en større anskaffelsesomkostning for slibeapparatet samt et større energiforbrug.The disadvantage of both of the abrasives mentioned above is that in order to be able to grind wide workpieces they must have long rollers, which means that the motor units for these rollers must be correspondingly larger. This results in a higher acquisition cost for the grinder as well as a higher energy consumption.

I US 2002/0068515 beskrives et overfladebehandlingsapparat, hvor enten en bom med en slibetromle og/eller en bom med et antal cirkulære slibebørster anvendes til overfladebehandling af et fortrinsvis fladt emne, og hvor slibebørsteme er vist arrangeret i to rækker forskudt for hinanden, således at den anden række af slibebørsters slibeområde lige akkurat overlapper slibeområdet af den første række slibebørster.US 2002/0068515 discloses a surface treatment apparatus wherein either a grinding drum bar and / or a plurality of circular grinding brushes is used for surface treatment of a preferably flat blank and wherein grinding brush bodies are shown arranged in two rows offset to each other so that the second row of abrasive brushes just exactly overlaps the abrasive area of the first row of abrasive brushes.

Denne opbygning af overfladebehandlingsapparat medfører, at der sker en uens overfladebehandling, da slibeområdeme af de to rækker slibebørster overlapper hinanden lidt, og at der kun sker én overslibning af emnets overflade.This construction of the surface treatment apparatus causes an uneven surface treatment as the abrasive areas of the two rows of abrasive brushes overlap slightly and only one surface of the workpiece is sanded.

Det betyder, at apparatet ikke vil sikre en effektiv afslibning/afgratning af kanter og rundinger på et emne, da eksempelvis en stationær slibetromle kun kan slibe overfladen og ffemadvendende kanter/rundinger, og en bom med overlapning af slibebørsternes slibeareal sikrer kun en overslibning af store dele af overfladen én gang.This means that the apparatus will not ensure an effective grinding / degrading of edges and roundings on a workpiece, for example, a stationary grinding drum can only grind the surface and five applying edges / roundings, and a boom with overlap of the grinding area of the grinding brushes ensures only a grinding of large parts of the surface once.

Formål med opfindelsenObjects of the Invention

Det er formålet med den foreliggende opfindelse at angive et slibeapparat, der er enkelt opbygget, og som ved hjælp af et antal bevægelige slibeelementer kan krydsslibe 5 et emne med kanter, rundinger og afgratninger ensartet, samtidig med at forbruget af slibepapir er minimalt.It is an object of the present invention to provide a simple construction grinder which can, by means of a plurality of movable grinding elements, cross-grind a workpiece with edges, rounds and scraps uniformly while minimizing the consumption of grinding paper.

Dette opnås ved hjælp af et slibeapparat som beskrevet i den indledende del af krav 1, og hvor nævnte bærearrangement omfatter et transportorgan for nævnte slibehoveder, 10 hvilket transportorgan er drevet af nævnte bevægemotorer.This is achieved by means of an abrasive apparatus as described in the preamble of claim 1, wherein said carrier arrangement comprises a transport means for said grinding heads, which transport means is driven by said moving motors.

Beskrivelse af opfindelsenDescription of the Invention

For at kunne slibe et emne i ét gennemløb igennem slibeapparatet er det udformet med et antal slibeelementer, der er drevet af nævnte slibemotorer, og som udgør et antal af 15 slibehoveder.In order to be able to grind a workpiece in one passage through the grinding apparatus, it is formed with a number of grinding elements driven by said grinding motors, which constitute a number of 15 grinding heads.

Disse slibehoveder er forbundet med et bærearrangement, der holder slibehovedeme i en ønsket position i forhold til emnets flade.These grinding heads are connected to a support arrangement which holds the grinding heads in a desired position relative to the surface of the workpiece.

20 I en foretrukket udførelsesform af opfindelsen er disse slibeelementer cirkulære slibeskiver, som er forbundet til slibemotoreme, således at de er placeret i det vandrette plan og fortrinsvist parallelt med en overflade af emnet, der skal slibes.In a preferred embodiment of the invention, these abrasive elements are circular abrasive discs which are connected to the abrasive motors so that they are located in the horizontal plane and preferably parallel to a surface of the workpiece to be abraded.

For at kunne slibe hele emnet ved ét gennemløb omfatter nævnte bærearrangement et 25 transportorgan for nævnte slibehoveder, hvilket transportorgan er drevet af nævnte bevægemotorer.In order to be able to grind the entire workpiece at one pass, said carrier arrangement comprises a conveying means for said grinding heads, which conveying means is driven by said moving motors.

Det medfører, at de enkelte slibeelementer, udover at de kan rotere om deres egen lodrette aksel, kan bevæges vandret på tværs af emnet i en retning vinkelret på slibeele-30 menternes lodrette aksel. Det sikrer, at hele emnet bliver slebet ved et gennemløb gennem slibeapparatet.As a result, the individual grinding elements, in addition to being able to rotate about their own vertical shaft, can be moved horizontally across the workpiece in a direction perpendicular to the vertical shaft of the grinding elements. This ensures that the entire workpiece is sanded during a passage through the grinder.

4 DK 2005 00267 U3 1 en foretrukket udførelsesform af opfindelsen er transportorganet en endeløs bane, der sørger for, at slibehovedeme bevæges rundt fra én side til modsatte side og tilbage igen til den første side, således at emnet ved et gennemløb igennem slibeapparatet bliver overfladebehandlet af to rækker slibehoveder.In a preferred embodiment of the invention, the conveying means is an endless web which causes the grinding heads to move around from one side to the opposite side and back again to the first side, so that the workpiece is surface-treated by a passage through the grinding apparatus. two rows of grinding heads.

På denne måde opnås en jævn slibning af emnet, da den anden række slibehoveder typisk vil slibe i modsat retning og derved rette op på de eventuelle ujævnheder, der er opstået ved den slibning, der er udført af den første række slibehoveder.In this way, an even grinding of the workpiece is achieved, as the second row of grinding heads will typically grind in the opposite direction, thereby rectifying any unevenness caused by the grinding performed by the first row of grinding heads.

I en udførelsesform af opfindelsen er slibeelementeme forbundet til slibemotoreme med en fast aksel, hvorved emner med ens tykkelse kan slibes på den opadvendende flade, da slibepapiret på alle slibeelementeme er parallelt med fladen.In one embodiment of the invention, the abrasive elements are connected to the abrasive motors with a fixed shaft, whereby articles of equal thickness can be abraded on the upwardly facing surface since the abrasive paper on all the abrasive elements is parallel to the surface.

I en anden udførelsesform af opfindelsen er slibeelementeme forbundet til slibemotoreme med en bevægelig aksel, eksempelvis en kardanaksel eller en aksel med et kug-le/skålled, hvorved emner med uens tykkelse kan slibes på den opadvendende flade, da slibepapiret nu vil kunne følge konturen af emnets flade.In another embodiment of the invention, the abrasive elements are connected to the abrasive motors with a movable shaft, for example a cardan shaft or a shaft / ball joint shaft, whereby objects of different thickness can be abraded on the upwardly facing surface as the abrasive paper will now be able to follow the contour of the surface of the subject.

For at forbedre slibningen og undgå ujævn slibning af emnet omfatter hvert slibehoved et slibeelement med tilhørende slibemotor, hvorved det er muligt at have forskellig rotationsretning for hvert enkelt slibeelement.In order to improve the grinding and to avoid uneven grinding of the workpiece, each grinding head comprises a grinding element with associated grinding motor, whereby it is possible to have different rotation directions for each grinding element.

For eksempel: hvert andet slibehoved kan have samme rotationsretning af slibeelementet, medens de mellemliggende slibehoveder har en modsatrettet rotationsretning, eller hvert tredje slibehoved kan have samme rotationsretning af slibeelementet, medens de mellemliggende slibehoveder har en modsatrettet rotationsretning.For example: every other abrasive head may have the same direction of rotation of the abrasive element, while the intermediate abrasive heads have an opposite direction of rotation, or every third abrasive head may have the same direction of rotation of the abrasive element, while the intermediate abrasive heads have an opposite direction of rotation.

De forskellige rotationsretninger af efterfølgende slibeelementer bevirker, at slibeapparatet med fordel vil kunne anvendes ved afgratning og slibning af kanter og rundinger.The different directions of rotation of subsequent abrasive elements mean that the abrasive apparatus can advantageously be used for deburring and grinding edges and roundings.

5 DK 2005 00267 U35 DK 2005 00267 U3

Den sideværts bevægelse af slibehovedeme skal være afstemt med den hastighed, hvormed emnet bliver ført igennem slibeapparatet, således at slibehovedeme i det mindste bevæges så hurtigt, at emnet får mindst to overslibninger, og der ikke er områder på emnet, der ikke bliver slebet.The lateral movement of the grinding heads must be aligned with the speed at which the workpiece is passed through the grinding apparatus, so that the grinding heads move at least so fast that the workpiece receives at least two sandings and there are no areas on the workpiece that will not be sanded.

For at bevæge slibehovedeme på tværs af indføringsretningen af emnet udgøres nævnte transportorgan af et antal drivkæder eller -remme, der er indrettet til at indgribe med et drivhjul, der er drevet af nævnte bevægemotorer.In order to move the grinding heads across the insertion direction of the workpiece, said conveying means is comprised of a plurality of drive chains or belts adapted to engage with a drive wheel driven by said moving motors.

I en foretrukket udførelsesform af opfindelsen er fire af disse drivhjul placeret rektangulært i bærerammen, således at slibehoveder, der er forbundet til transportorganet, først bevæges på tværs af emnet og derefter tilbage tværs over emnet.In a preferred embodiment of the invention, four of these drive wheels are positioned rectangular in the support frame so that grinding heads connected to the conveyor are first moved across the workpiece and then back across the workpiece.

Er transportorganet en drivkæde, vil drivhjulene være tandhjul, der går i indgreb med drivkæden og derved driver transportorganet med slibehoveder rundt.If the transport means is a drive chain, the drive wheels will be gears that engage the drive chain and thereby drive the transport means with grinding heads around.

Er transportorganet en drivrem i form af en kilerem, vil drivhjulene være enten glatte drivhjul, der ved hjælp af modstandskraften mellem kilerem og drivhjul vil drive transportorganet med slibehoveder rundt, eller være et tanddrivhjul, der går i indgreb med en fortandet side af kileremmen.If the conveyor is a drive belt in the form of a V-belt, the drive wheels will be either smooth drive wheels which, by means of the resistance between the V-belt and drive wheels, will drive the conveyor with grinding heads around, or be a gear drive which engages a toothed side of the V-belt.

Alternativt kan transportorganet være wirer eller brede bånd eller lignende, hvor drivhjulet henholdsvis er et smalt drivhjul eller en valse.Alternatively, the conveying means may be wires or wide belts or the like, the drive wheel being a narrow drive wheel or roller, respectively.

I stedet for at have drivhjulene opsat rektangulært i bærerammen kan drivhjulene tænkes opsat i andre polygonale arrangementer som for eksempel: - tre drivhjul placeret i en trekant, eller - fem drivhjul placeret i en femkant.Instead of having the drive wheels mounted rectangularly in the support frame, the drive wheels may be conceived in other polygonal arrangements such as: - three drive wheels placed in a triangle, or - five drive wheels located in a pentagon.

Alternativt kan der anvendes kun to drivhjul, som transportorganet kører rundt om, således at de to rækker af slibehoveder er placeret umiddelbart efter hinanden. Det sætter krav til, at slibeelementeme ikke må have en for stor diameter, da slibehovederne ellers ikke kan passere hinanden på tværs af emnet.Alternatively, only two drive wheels can be used, which the conveying means drive around, so that the two rows of grinding heads are located immediately after each other. This requires that the grinding elements must not be too large in diameter, since otherwise the grinding heads cannot pass each other across the workpiece.

6 DK 2005 00267 U36 DK 2005 00267 U3

Det vil være en fordel, at de to rækker af slibehoveder bevæger sig på tværs af emnet i en vis afstand, da der så er tid og plads til, at afslebet materiale fra den første række slibehoveder kan flyttes væk fra emnet og således ikke forhindrer den anden række af 5 slibehoveder i at foretage en optimal slibning.It will be advantageous for the two rows of grinding heads to move across the blank at some distance, since there is time and space for the grinding material from the first row of grinding heads to be moved away from the blank and thus not prevent it. second row of 5 grinding heads in making an optimal grinding.

I stedet for at have drivhjul, der er forbundet til en bevægemotor i alle hjørner afbærerammen, kan en del af disse drivhjul være medløbshjul, der kun er placeret for at lede transportorganet.Instead of having drive wheels connected to a moving motor in all corners of the support frame, a portion of these drive wheels may be idler wheels located only to guide the conveyor.

10 I en foretrukket udførelsesform af opfindelsen er transportorganet en bred tandrem, der kører rundt på to store tandhjul, der er placeret med et tandhjul i hver side af slibeap-paratet. På tandremmen er slibehovedeme placeret.In a preferred embodiment of the invention, the conveyor means is a wide toothed belt running around two large gears located with a gear in each side of the grinding apparatus. The grinding heads are located on the toothed belt.

15 Da et slibeapparat skal kunne anvendes til emner af forskellig tykkelse eller til emner med forskellig tykkelse, omfatter det et apparatstel, hvori nævnte bærearrangement er højdejusterbart arrangeret ved hjælp af et antal forskydningskraftgivere.As an abrasive device must be capable of being used for items of different thickness or for items of different thickness, it comprises an apparatus frame in which said supporting arrangement is height adjustably arranged by a plurality of shear energizers.

Da bærerammen med slibehoveder har en anselig vægt anvendes der et antal forskyd-20 ningskraftgivere for at hæve/sænke bærerammen i apparatstellet.Since the support frame with abrasive heads has a considerable weight, a number of displacement energizers are used to raise / lower the support frame in the apparatus frame.

Det medfører, at bærerammen kan placeres i en indstillet højde i apparatstellet, hvorved slibeelementeme placeres således, at de sliber en præcis tykkelse af emnet.This means that the support frame can be placed at a set height in the apparatus frame, whereby the abrasive elements are positioned to grind an exact thickness of the workpiece.

25 Forskydningskraftgi verne kan være cylindere, tandstang/tandhjulsarran gementer, me kaniske vippearrangementer, rotationsarrangementer eller lignende, der kan være drevet hydraulisk, pneumatisk eller elektrisk.The shear forces may be cylinders, rack / pinion assemblies, mechanical tapered arrangements, rotary arrangements or the like, which may be hydraulically, pneumatically or electrically driven.

Det at bærerammen kan højdejusteres gør det nemt at bringe bærerammen op i en høj-30 de, hvor det er nemt at komme til at udskifte slibeelementeme.The height-adjustable support frame makes it easy to raise the support frame to a height where it is easy to replace the grinding elements.

Slibeelementeme kan udgøres af: 7 DK 2005 00267 U3 - slibeskiver, der monteres på en slibeskive, eksempelvis ved hjælp af velcroflader, eller - slibeskiver, der er udformet med en tap, der forbindes til slibemotoremes aksel, eksempelvis ved skruefatning.The abrasive elements can be: 7 DK 2005 00267 U3 - abrasive discs mounted on an abrasive disc, for example by means of Velcro surfaces, or - abrasive discs which are formed with a pin which is connected to the shaft of the abrasive motors, for example by screw mounting.

På disse måder kan slibeelementer skiftes hurtigt og nemt, således at det ikke er nødvendigt at have lange produktionsstop, når der skal skiftes slibeelementer.In these ways, abrasive elements can be changed quickly and easily, so that it is not necessary to have long production stops when replacing abrasive elements.

Endvidere kan slibehovedeme have slibeelementer med forskellige emner som for eksempel slibepapir, slibebørster, stålbørster, pudseklude eller børster.Furthermore, the abrasive heads may have abrasive elements with various items such as abrasive paper, abrasive brushes, steel brushes, cleaning cloths or brushes.

Et slibeapparat ifølge den foreliggende opfindelse kan finde anvendelse inden for træbranchen, men den kan også finde anvendelse inden for andre brancher, hvor der er flader, der skal slibes, for eksempel i automobilbranchen, hvor pladedele til køretøjer skal slibes.A grinding device according to the present invention may be used in the wood industry, but it can also be used in other industries where there are surfaces to be sanded, for example in the automotive industry where plate parts for vehicles are to be sanded.
