Figure 2 is a perspective view of a planetary disk with a grinding wheel, Figure 3 is a perspective view of a planetary disk with two grinding wheels. Figures 4A to 4D show a principle view of a planetary disk with 2 to 5 grinding wheels, fi Figs. 5a to 5c a principle view of a planetary disk with 3 different operating constellations, a planetary disk and a grinding wheel with an identification device in the form of RFDI transmitters / receivers, and Figure 8 shows diagrams of identification systems.

I figurerna 1- 5 visas i princip ett antal varianter av anordningen enligt uppfinningen vad gäller utformningen av stativ, med roterande planetskiva och ett varierande antal roterande sliprondeller. Så visar figur 1 schematiskt en vy av en anordning enligt uppfinningen med ett stativ 11, vari en planetskiva 12 är fritt roterbar. l planetskivan visas två elmotorer 13 för drivning av varsin sliprondell 14 Som framgår av figurerna 4A- 4D kan planetskivan 12 uppbära 2,3,4 eller 5 sliprondeller. Som framgår av figur 5a kan sliprondellerna 14 antingen drivas av varsin elmotor 13, eller enligt figur 5b och 5c där två eller tre sliprondeller 14 drivs av varsin elmotor 13, medan en sliprondell 14 drivs gemensamt med en annan sliprondell medelst en drivrem 15.Figures 1-5 show in principle a number of variants of the device according to the invention with regard to the design of the frame, with a rotating planetary disc and a varying number of rotating grinding wheels. Figure 1 schematically shows a view of a device according to the invention with a stand 11, in which a planetary disk 12 is freely rotatable. The planetary disk shows two electric motors 13 for driving each grinding wheel 14. As can be seen from Figures 4A-4D, the planetary disk 12 can support 2,3,4 or 5 grinding wheels. As shown in Figure 5a, the grinding wheels 14 can either be driven by electric motors 13 each, or according to Figures 5b and 5c where two or three grinding wheels 14 are driven by electric motors 13 each, while a grinding wheel 14 is driven in common with another grinding wheel by means of a drive belt 15.

Av figur 2 framgår hur sliprondellens 14 rotationsriktning A genom den friktion som skapas mot underlaget förmår planetskivan 12 att rotera i riktningen B. Förhållandet mellan rotationshastigheterna A och B beror på friktionen mot den yta som skall slipas och planetskivans tröghetsmoment.Figure 2 shows how the direction of rotation A of the grinding wheel 14 through the friction created against the ground causes the planetary disk 12 to rotate in the direction B. The relationship between the rotational speeds A and B depends on the friction against the surface to be ground and the moment of inertia of the planetary disk.

En speciell utföringsform av anordningen enligt uppfinningen framgår av figur 3 och 4a. Här uppbär en planetskiva 12 två sliprondeller 14a och 14b, roterande kring axlar med olika avstånd till planetskivans 12 rotationsaxel.A special embodiment of the device according to the invention appears from Figures 3 and 4a. Here, a planetary disk 12 carries two grinding discs 14a and 14b, rotating about axes at different distances from the axis of rotation of the planetary disk 12.

Av figur 3 framgår, att sliprondellens 14a rotationsriktning A skapar en motsatt rotationskraft B på planetskivan 12. För att kontrollera rotationen hos planetskivan 12 uppbär planetskivan 12 en andra sliprondell 14b, som roterar med en andra rotationsriktning D, i förhållande till rotationsriktningen A, vilken rotationsriktning D skapar en rotationskraft C, motverkande rotationskraften B.Figure 3 shows that the direction of rotation A of the grinding wheel 14a creates an opposite rotational force B on the planetary disk 12. To control the rotation of the planetary disk 12, the planetary disk 12 carries a second grinding wheel 14b, which rotates with a second direction of rotation D, relative to the direction of rotation D creates a rotational force C, counteracting the rotational force B.

Figur 6 visar en bandslipmaskin med ett stativ 26, i vilket två trummor 27,28 är lagrade, uppbärande ett slipband 29. Trummorna drivs av en elmotor 30 via en drivrem 31. 536 101 3. l figur 7 visas så för en utföringsform av anordningen enligt uppfinningen med en planetskiva 12 och en sliprondell 14 delar av identifieringssystemet, d v s en RFlD- såndarelmottagare 17 på planetskivan 12 och en motsvarande transponder, RFID- tag 16 på slipskivan. På motsvarande sätt visas i figur 6 på en bandslipmaskin en RFID-sändare/mottagare 17 på stativet 26 och en RFID-tag på slipbandet 29.Figure 6 shows a belt grinding machine with a stand 26, in which two drums 27, 28 are mounted, supporting a grinding belt 29. The drums are driven by an electric motor 30 via a drive belt 31. 536 101 3. Figure 7 is thus shown for an embodiment of the device according to the invention with a planetary disk 12 and a grinding wheel 14 parts of the identification system, i.e. an RF1D transmitter receiver 17 on the planetary disk 12 and a corresponding transponder, RFID tag 16 on the abrasive disk. Similarly, Figure 6 shows on an belt sander an RFID transmitter / receiver 17 on the stand 26 and an RFID tag on the belt 29.

Med hänvisning till fig. 8 som schematiskt visar anordningens 10 styrning varvid planetskivan 12 och respektive sliprondell 14 är förbunden med ett styrsystem 19 för styrning av sliprondellernas 14 rotationsriktning och rotationshastighet och för indirekt reglering av planetskivans 12 rotationsvarvtal och rotationsriktning genom styrningen av sliprondellerna 14. Styrsystemet 19 innefattar rotationsgivare 21 eller motsvarande för övervakning av planetskivans 12 och respektive sliprondells 14 rotationshastighet och rotationsriktning. Styrsystemet 19 åstadkommer en återkoppling av de rörliga delarnas, d v s planetskivans 12 och sliprondellernas 14 positioner. Via återkopplingen av de rörliga delarnas positioner regleras planetskivans 12 rotationsvarvtal och rotationsriktning genom val av olika rotationsvarvtal och rotationsriktningar genom val av olika rotationsvarvtal och rotationsriktningar på sliprondellerna 14. Anordningen 10 i enlighet med uppfinningen medför stor flexibilitet beträffande rotationsvarvtal och rotationsriktning på sliprondellerna 14 i förhållande till planetskivans 12 rotationsvarvtal och rotationsriktning.With reference to fi g. 8 which schematically shows the control of the device 10, the planetary disk 12 and the respective grinding wheel 14 being connected to a control system 19 for controlling the direction and rotation speed of the grinding wheels 14 and for indirectly controlling the rotational speed and direction of rotation of the planetary disc 12 by controlling the grinding wheels 14. The control system 19 comprises rotation sensor 21 or corresponding to monitoring the rotational speed and direction of rotation of the planetary disk 12 and the respective grinding wheel 14. The control system 19 provides a feedback of the positions of the moving parts, i.e. the planetary disc 12 and the grinding discs 14. Via the feedback of the positions of the moving parts, the rotational speed and direction of rotation of the planetary disk 12 is regulated by selecting different rotational speeds and directions of rotation by selecting different rotational speeds and rotational directions on the grinding wheels 14. The device 10 provides great flexibility in rotational speed and direction of rotation. the rotational speed and direction of rotation of the planetary disk 12.

En motor 13 kan även tänkas driva fler sliprondeller 14. Motorerna 13 är exempelvis anordnade eller placerade i planetskivan 12. Sliprondellerna 14 är direkt eller indirekt drivna av motorerna 13.A motor 13 is also conceivable to drive more grinding wheels 14. The motors 13 are for instance arranged or placed in the planetary disc 12. The grinding wheels 14 are directly or indirectly driven by the motors 13.

Styrsystemet 19 innehåller för golvet lämpligt styrprogram 25, så att operatören har full kontroll på processen via ett användargränssnitt 20, som kan vara ett antal vred och knappar, eller en datapanel. Anordningens 10 styrsystem 19 behöver läsa in olika styrprogram 25 via exempelvis en dator 18 som definierar förhållandet mellan planetskivans 12 och sliprondellernas 14 rotationshastighet och rotationsriktning. Det skall även vara möjligt att läsa in olika reglerförfaranden 24 som definierar sekvensen för att uppnå det önskade förhållandet, samt att behålla det i drift. 535 '|Û'l 4.The control system 19 contains a control program 25 suitable for the floor, so that the operator has full control of the process via a user interface 20, which can be a number of knobs and buttons, or a data panel. The control system 19 of the device 10 needs to read in various control programs 25 via, for example, a computer 18 which defines the relationship between the rotational speed and direction of rotation of the planetary disk 12 and the grinding discs 14. It must also be possible to load different control procedures 24 that define the sequence in order to achieve the desired ratio, as well as to keep it in operation. 535 '| Û'l 4.

Anordningens 10 kommunikation kan ske via Ethernet, trådlöst Ethernet, eller annat lämpligt trâdbaserat eller trådlöstbussystem. Matningsspänning, eller trådbaserad kommunikation till och från den roterande planeten 12 sker via rotationskontakter 23. Kommunikationssystemet mellan styrsystemet 19 och motorer 13 sker via ett passande bussystem. Motorerna 13 har som regel inbyggda rotationsgivare 21, annars kan externa rotationsgivare användas. Även motorernas drivsteg 22 kan innehàllas i planetskivan 12. Alla elektriskt drivna motorer 13 kan användas, som t ex stegmotorer 13, servomotorer 13, DC-motorer 13 eller asynkronmotorer 13. Andra sensorer och aktörer i anordningen 10 såsom rotationsgivare 21 för planetskivan 12 och RFID sändare/mottagare 17 och RFID- Tag 16 är antingen direkt kopplade till styrsystemet 19 eller kopplade via ett bussystem. I vissa fall kan det behövas rotationskontakter 23.The communication of the device 10 may be via Ethernet, wireless Ethernet, or other suitable wired or wireless bus system. Supply voltage, or wire-based communication to and from the rotating planet 12 takes place via rotary contacts 23. The communication system between the control system 19 and motors 13 takes place via a suitable bus system. The motors 13 usually have built-in rotary sensors 21, otherwise external rotary sensors can be used. The drive stage 22 of the motors can also be contained in the planetary disk 12. All electrically driven motors 13 can be used, such as stepper motors 13, servomotors 13, DC motors 13 or asynchronous motors 13. Other sensors and actuators in the device 10 such as rotation sensor 21 for the planetary disk 12 and RFID transmitter / receiver 17 and RFID Tag 16 are either directly connected to the control system 19 or connected via a bus system. In some cases, rotary contacts 23 may be required.
