Definitions

  • the invention relates to a system for automatic grinding of curved surfaces, in particular body surfaces of a motor vehicle to be painted, according to the preamble of the main claim.
  • a primer is first applied to the body sheet after priming, which serves as the basis for the top coat. Before applying the top coat, this filler must be smoothed by sanding.
  • the object of the invention is to further automate a generic system, in particular the exchange of the sanding sheet should also be taken over by the system.
  • the system therefore has an abrasive sheet magazine that keeps unused abrasive sheets ready for replacement. Furthermore, a device is provided with the tasks of removing the used sanding sheet from the sanding plate and enabling automatic attachment of the new sanding sheet. Finally, the grinding unit includes a clamping device, by means of which the grinding sheet can be loosened or fastened. The clamping device itself can be rotated relative to the axis of the grinding plate.
  • a clamping device overcomes dii. Difficulties that arise when replacing a glued sanding sheet according to the prior art. Due to the clamping device, the sanding sheet is no longer firmly connected to the contact surface of the grinding plate, it is only held by the clamping device. By loosening the clamping device, it can therefore be easily removed from the sanding plate.
  • the clamping device is rotatably held relative to the grinding plate in accordance with the teaching according to the invention.
  • This initially does not result in any real drive connection between sanding sheet and sanding disc.
  • the sanding sheet is pressed against the sanding plate and the frictional connection resulting from the friction takes the sanding sheet with it.
  • This effect only occurs when the frictional forces between the sanding surface and the sanding sheet are smaller than those between the sanding sheet and sanding plate. This can easily be achieved by selecting a suitable sanding sheet and the material of the sanding plate.
  • Sanding sheets with a lattice structure and open meshes are used for sanding car bodies, while the sanding plate is made of a soft, elastic material. In this way, the lattice threads of the sanding sheet can press into the sanding plate during grinding and find the anchoring necessary for the frictional connection.
  • the sanding sheet is also taken along when the sanding plate is already rotating but has not yet been placed on the surface to be sanded. This is due to the breakaway forces of the rotatably mounted clamping device and its inertia, to which the inertia of the sanding sheet is added.
  • curved surfaces can be ground fully automatically. As in the prior art, the grinding unit is guided mechanically. In addition, there is no longer any need for manual intervention when replacing the sanding sheets.
  • the cost-effective use of such a system is appropriate where a large number of similar, curved surfaces have to be ground, as is the case, for example, in automobile construction.
  • the system can be easily integrated into the production process.
  • the system can also be used to achieve polished surfaces of consistently high quality. This is due to the machine-guided grinding unit, which travels through the same grinding tracks with the same pressure during each grinding process.
  • the sanding sheet is always changed after a certain number of sanded surfaces. The time of changing the sanding sheet is therefore not subject to the more or less correct assessment of a worker.
  • the system is advantageously controlled electronically.
  • the sanding sheet magazine is designed as a hollow cylinder open at the top, which receives the sanding sheets, which are generally round, layered one above the other.
  • the sanding sheets are successively removed from above.
  • the inside diameter of the hollow cylinder corresponds approximately to the diameter of the sanding sheets. With this measure you are already in the correct position for removal.
  • sanding sheets are generally used which have a lattice structure with open meshes and to which an abrasive grain is applied on both sides. Such grinding wheels are relatively stiff in the dry state and must therefore be "soaked” before use.
  • the hollow cylinder is therefore filled with water. However, for certain reasons, which will be explained later, the water must not reach the upper sanding sheets.
  • Claim 4 shows an advantageous embodiment of a device for exchanging the sanding sheet.
  • a support table with a central recess is provided to fasten the sanding sheet, onto which the sanding unit, as also detailed below, presses the sanding sheet and thus firmly for the clamping process holds.
  • a container filled with liquid, usually water, is provided to loosen the sanding sheet.
  • the sanding plate with the adhering sanding sheet and released clamping device plunges into it.
  • the surface tension of the liquid retains the sanding sheet in the liquid when the grinding plate is moved back, which then slowly sinks to the bottom of the container.
  • the system automatically uses an abrasive sheet that can be used on both sides.
  • claims 5 and 6 provide a sieve plate which can be immersed in the container with a swivel arm. The sinking sanding sheet is caught by the sieve plate and brought out of the container by swiveling the sieve plate. If it is a sanding sheet that can be used on both sides, by swiveling the sieve plate further, the sanding sheet can be rotated 180 degrees and returned to the sanding sheet magazine, where it is ready for a new sanding insert. If it is a sanding sheet that can be used on one side or if both sides of the sanding sheet are already worn, it is placed in a corresponding waste container by swiveling the sieve plate.
  • the edge of the sieve plate immersed in the liquid container expediently tapers downwards to the diameter of the sanding sheet.
  • the sinking sanding sheet is centered in the sieve plate in a position that allows the subsequent return to the sanding sheet magazine without further ado.
  • the clamping device consists essentially of a clamping cone and a counter between which the fastening tabs of the sanding sheet are clamped.
  • the clamping cone can be operated hydraulically.
  • the grinding water serves as hydraulic medium, which otherwise escapes via a flow channel in the clamping cone. When actuated, this flow channel is blocked by increasing the grinding water inflow via a valve flap. If the grinding water is not to be supplied via the clamping cone, it can also be operated pneumatically.
  • the clamping cone and the counter stop can be rotated in relation to the sanding plate.
  • they are designed so that they can also perform an axial movement in the direction of the grinding plate axis. This measure prevents wrinkles of the fastening tabs of the sanding sheet in the clamping area which cause grinding grooves, which folds can occur if the sanding plate is compressed somewhat during the sanding process.
  • the drive connection between the grinding spindle and grinding plate takes over in an advantageous embodiment according to claims 15-17, a connecting cable that leads through the grinding spindle and is attached with its ends diametrically opposite to the grinding plate. Swivel-mounted clamping jaws are expediently provided for this.
  • the connecting cable at the fastening points is not excessively stressed to bend.
  • This drive connection ensures that the grinding disc runs optimally even when the grinding disc is inclined with respect to the grinding spindle.
  • Such an inclination of the grinding spindle is a prerequisite for grinding curved surfaces. Otherwise the grinding unit would have to have a curved path.
  • the inclination itself takes place via the universal joint provided above the grinding plate.
  • the sanding plate is connected to the grinding spindle via a universal joint.
  • the universal joint is advantageously arranged directly above the sanding plate, so that only a small distance can form between it and the work surface. This prevents the grinding plate from buckling when the grinding unit is placed on the surface to be ground.
  • FIG. 1 a system for automatic grinding of curved surfaces is shown schematically.
  • a rectangular frame 1 with guides 2 can be seen and 3, on which tables 4 and 5 can be moved in the longitudinal direction.
  • the displaceability of tables 4 and 5 should indicate the double arrows 6 and 7.
  • a crossbar 8 is also attached to the frame 1. This hangs a grinding unit 9 and enables it to be moved in the direction of the double arrow 10.
  • the table 5 serves to receive the sunroof of a vehicle body.
  • the table 4 carries a device for automatically exchanging a used sanding sheet for an unused one on the sanding unit 9 or for turning a sanding sheet used on one side.
  • an abrasive sheet magazine 11, a container 12 filled with liquid, a sieve plate 13 immersed therein, and a support plate 14, which has a central through-bore 14a are arranged on the table 4.
  • the sanding sheet magazine 11, the container 12 and the support plate 14 are in alignment, as indicated by the line 15.
  • a swivel arm 17 connects the sieve plate 13 to a double swivel joint 18, which once allows a rotary movement about an axis running parallel to the guides 2, 3. This is shown in FIG. 2 by an arrow 19. Furthermore, the swivel joint 18 allows rotation and a vertical axis running in the plane of the drawing. The arrow 20 stands for this rotary movement.
  • Fig. 1 nor L e NEN waste container 16 is for the storage of spent Scrleifcun.
  • FIG. 2 shows the system of FIG. 1 in the direction of arrow Z. Again, the system is shown only schematically.
  • the grinding unit 9 is immersed in the container 12. The table is then under the crossbar 8.
  • the grinding magazine 11 consists of a hollow cylinder in which round grinding sheets 21 are stacked.
  • the hollow cylinder has feed lines 11a, 11b and a drain 11c. It is supplied with water via these lines.
  • a push rod 22 pierces the hollow cylinder from below.
  • a plate is attached on which the stack of sanding sheets lies.
  • an actuator for example a hydraulic cylinder, the stack can be adjusted accordingly via the push rod when a sanding sheet is removed.
  • the container 12 is also provided with similar discharge and supply lines 12a, 12b.
  • This container 12 is also filled with water.
  • Fig. 2 also indicates with a double arrow 23 and a movement path 24 that the grinding unit 9, guided on the crossbar, move up out of the container 12, move sideways and can be lowered into the grinding sheet magazine 11 and onto the support plate 14.
  • FIG. 2 shows in broken lines individual positions of the swivel arm 17 with the sieve plate 13. In FIG. 2 it can be seen that the edge of the sieve plate 13 immersed in the container 12 tapers downward.
  • the holding of the support plate 14 on the table 4 is also indicated by dash-dotted lines. The same applies to the swivel joint 18.
  • FIG. 3 shows the lower section of the grinding unit 9.
  • the upper section, not shown, of the grinding unit receives the drive motor; the drive motor is therefore an integral part of the grinding unit.
  • this is composed of a grinding spindle 25, which is in a bearing block 26 is rotatably supported via roller bearings 27 and 28.
  • a spherical bearing inner ring 29 of a universal joint is fastened to the lower section of the grinding spindle 25.
  • the corresponding bearing outer ring 30 is located in a grinding plate carrier 31, to which the grinding plate 32 is in turn fastened via a spacer disk 31a.
  • the grinding plate 32 is held on the spacer 31a via a bayonet lock.
  • the sanding plate 32 itself consists of a soft, elastic foam, the upper side of which is covered with a stiff fastening plate 32a which is appropriately shaped for the bayonet locking.
  • a clamping device 33 holds a sanding sheet 21 on the underside of the sanding plate 32.
  • the abrasive sheet 21 has fastening tabs 21 a, which are held by the clamping device 33, by means of star-shaped slots.
  • the sanding sheet 21 consists of a lattice-like fabric with open meshes. An abrasive grain is applied on both sides so that the abrasive sheet 21 can be used on both sides.
  • the grinding spindle 25 has two channels running approximately in the axial direction, a grinding water supply channel 25a and an air guide channel 25b. These channels are fed via feeds 26a and 26b in the bearing block 26.
  • FIG. 4 shows on an enlarged scale the course of the channels in the lower section of the grinding spindle.
  • the feed channel 25a opens into a funnel-shaped space which is formed in a sleeve 34 which is pushed into the grinding spindle 25 from below and has an outer diameter which is offset.
  • a plastic hose 35 which is held displaceably within the sleeve 34 and whose displaceability is indicated by the broken line in the funnel-shaped cavity leads from the cavity down to the clamping device 33.
  • the feed channel 25 serves to supply the sanding sheet with grinding water and to hydraulically actuate the clamping device 33, as will be described further below.
  • the air duct 25 b branches off above the sleeve 34, runs from there in a component 36 which is firmly connected to the grinding spindle 25, and leads again in the offset region of the sleeve 34 back into the grinding spindle 25 and occurs at its lower end, So below the bearing inner ring 29.
  • the task of the air duct 25b is explained in more detail in connection with FIG. 5.
  • 4 shows a stopper 37, an O-ring around the sleeve 34, and a groove ring seal 38 below the funnel-shaped opening of the sleeve 34.
  • FIG. 3 shows a bellows 39 which is connected to the grinding plate carrier 31 and to a component 40 fastened to the grinding spindle 25.
  • the task of this bellows is to protect the universal joint and the drive device to be shown in more detail from contamination. In addition, due to its inherent elasticity, it should bring about a return of the grinding plate 32 to a horizontal position.
  • a clamping cone 41 and a counter stop 42 can first be seen here.
  • the counter stop 42 extends upwards into a cylindrical section 42 a, which is fastened to the grinding plate carrier 31 Guide sleeve 43 receives.
  • a hollow cylinder 44 is fastened to the counterblow 42 and is made airtight, axially displaceable and rotatable with an upper section in the guide sleeve 43.
  • the upper section of this hollow cylinder 44 is closed by a carrier plate 45 attached to it. Between the carrier plate 45 and the guide sleeve 43 there is also an unspecified ring seal.
  • the carrier plate 45 finally receives the lower end of the plastic hose 35.
  • the guide sleeve 43 forms an inner flange 43a, which also slides against the hollow cylinder 44, and accordingly an annular collar 44a is provided on the hollow cylinder 44, which in turn slides against the inner wall of the guide sleeve 43.
  • the counter-stop 42 can be rotated relative to the guide sleeve 43 and displaced in the axial direction, the axial displaceability being limited by the annular collar 44a and the inner shoulder 43a.
  • the clamping cone 41 carries on its side facing the counter stop 42 a further guide sleeve 46 which is guided in the hollow cylinder 44 in a watertight manner.
  • the clamping cone 41 penetrates a screw 47 with a stepped through hole 47a.
  • This through hole serves as a flow channel for the grinding water.
  • a compression spring 48 is arranged in the through hole 47a and acts on a valve cap 49 pushed over the shaft of the screw 47. It holds the inner cap base provided with a rubber seal somewhat away from the shaft end of the screw 47, so that there is a flow through wall holes 49a of the valve cap 49 to the through hole 47a of the screw 47.
  • a nut 50 turned on the screw 47 braces the clamping cone 41 and the guide sleeve 46 with the screw 47.
  • the connection is sealed under the nut 50 via an O-ring.
  • the nut 50 also serves as an anchor for a tension spring 51, the other end of which is suspended in the carrier plate 45.
  • the grinding unit 9 gets a sanding sheet 21 from the sanding sheet magazine 11.
  • the sanding sheet 21 adheres to the underside of the wet sanding plate 32 due to a film of water or the resulting adhesion.
  • the sanding unit now lowers on the support plate 14a until it lies snugly there.
  • the fastening tabs 21a of the sanding sheet 21 protrude horizontally. Now the flow rate of the grinding water is suddenly increased and a backflow forms in the guide sleeve 46, with the result that the valve cap 49 is pressed against the force of the compression spring 48 on the screw 47.
  • the screw shaft thereby closes the through bores 49a, so that the grinding water can no longer escape downwards.
  • the pressure prevailing in the guide sleeve 46 increases due to the grinding water being fed in and the guide sleeve 46 moves down together with the clamping cone 41 against the force of the spring 51.
  • the clamping cone 41 penetrates the fastening tabs 21a, which then spring back into the horizontal plane due to their elasticity.
  • the pressure of the grinding water is reduced by a corresponding valve in the feed line 26a (not shown in FIG. 3), with the result that the tension spring 51 pulls the clamping cone 41 back again. Because of its conical design, it takes the fastening tabs 21a upwards and presses it against the counter stop 41.
  • the force of the tension spring 51 is sufficient to clamp the fastening tabs 21a sufficiently.
  • This can be supported, as indicated in FIG. 5, by rubber O-rings. which are inserted in the lateral surfaces of the clamping cone and counter stop. This increases the friction between the sanding sheet flaps and the clamping device. Since the clamping cone and the counter stop are rotatably held relative to the guide sleeve 43, the sanding sheet 21 can thus also be rotated relative to the sanding plate 32.
  • the grinding plate 32 consists of a soft foam material. Now places the grinding unit on the surface to be ground, the grinding plate 32 compresses in accordance with the load. If the clamping device were held axially immovably in the guide sleeve 43, the sanding sheet would form folds in the area of the fastening tabs 21a when the sanding plate 32 is compressed, which could lead to scoring in the sanding surface. In order to prevent this danger, the clamping device is axially displaceable relative to the guide sleeve 43 in the manner mentioned.
  • the actual displacement is controlled via the air duct 25b, by means of which a vacuum is built up in the chamber 43a of the guide sleeve 43, at least during the grinding process, which pulls the clamping device upwards against the tensile force of the clamped fastening tabs 21a during grinding.
  • the plastic hose 35 also moves upwards and projects into the funnel-shaped recess of the sleeve 34 into (Fig. 4). Since the curved surface of the grinding plate must wobble relative to the grinding spindle when grinding, the end of the plastic hose 35 in the funnel-shaped opening can also participate in this movement.
  • the air duct 25b has another task.
  • overpressure is briefly built up in the chamber 43a (FIG. 5), which forces the clamping device to move down as far as the stop (inner flange 43a). This position must be taken by the clamping device when changing the sanding sheet, since otherwise it is not guaranteed that the clamping cone 41 can grip the fastening tabs 21a during the retraction process.
  • a connecting cable 52 can be seen, which runs through a transverse bore in the grinding spindle 25 and is deflected in the opposite direction via guide rollers 53, 54.
  • the ends of the connecting cable 52 are fastened diametrically opposite to the grinding plate carrier 31.
  • the guide rollers 53, 54 rotate in bearing housings 53a, 54a, which in turn are rotatably mounted on the component 36.
  • the carriage 4 is to be located under the crossbar 8 at the starting position and the grinding unit 5 with its grinding plate should be immersed in the container 12 filled with water.
  • the sieve plate 13 is also located below the grinding plate in the container 1 2.
  • An uncut sunroof is attached to the slide 5.
  • the grinding unit 9 After starting, the grinding unit 9 emerges from the container 12 and its grinding plate begins to rotate. As a result, the sanding sheet lies flat on the underside of the sanding plate, where it adheres without rotation due to the adhesive effect that will result from the water film located there.
  • the grinding unit 9 moves down, with its rotating grinding plate on the sunroof.
  • grinding water begins to flow out of the clamping cone. Now the actual grinding begins.
  • the grinding unit moves to the left (in Fig. 1) and back along the crossbar.
  • the slide oscillates perpendicular to it.
  • the sunroof on these wines is ground in several paths.
  • the grinding unit 9 rises and the carriage 5 moves back into its starting position.
  • the grinding unit has the position shown in Fig. 1.
  • the carriage 4 moves under the crossbar 8 and the grinding unit lowers into the container 12 filled with liquid (FIG. 2). With the lowering, the clamping cone is released at the same time in the manner described above. Due to the laws of physics, the adhesive effect between the open mesh sanding sheet and the underside of the immersed sanding plate is eliminated. If the grinding unit 9 lifts out of the container 12 again, the grinding sheet is pulled off the clamping cone 41 due to the surface tension of the liquid and remains in the container. It sinks slowly and is caught by the sieve plate 13.
  • the sanding unit 9 now travels along the movement path 24 to the sanding sheet magazine 11 and lowers onto the sanding sheet located at the top.
  • the sanding plate is still wet.
  • the water cycle in the sanding sheet magazine ensured that all of the sanding sheets were "soaked” overall, but at least the top two were only moistened. In this sense, moistened means that the open meshes of the lattice structure are not filled with water. This is achieved by briefly blowing out these abrasive sheets at the top with a compressed air nozzle (not shown in the drawing) or through the water outlet 11c below the upper abrasive sheets.
  • the moistened top sanding sheet sticks to the sanding pad due to the wet sanding pad.
  • the grinding unit 9 rises then up again and at the same time moves to the support plate 14 and lowers on it until the sanding plate lies snugly there. Now the grinding sheet is clamped as described above.
  • the grinding unit 9 lifts again and travels along the cross-beam 8 into its starting position in order to be prepared for a new grinding process.
  • the carriage 5 is also equipped with a new sunroof.
  • the arm 17 pivots the sieve plate 13 out of the container 12.
  • the deposited first sanding sheet lies on it with the used side down. Because of the adhesion that is caused by the water and the lattice structure of the sanding sheet and the sieve plate, the sanding sheet sticks to the sieve plate.
  • the swivel arm 17 swivels 180 degrees over to the sanding sheet magazine 11. The abrasive sheet falls into it by striking the sanding sheet magazine a little more forcefully. It is now with the unused side down. So it was turned by 180 degrees and is ready for a new grinding operation. The swivel arm 17 swings back into the container 12.
  • the push rod 22 (FIG. 2) of the sanding sheet magazine (11) belonging to a pneumatic cylinder ensures that the sanding sheet stack is always raised up to the working height of the sanding plate.
  • the swivel arm 17 first swivels only 90 degrees upward, then turns in the direction of arrow 20 (FIG. 1) and finally swivels another 90 degrees over the waste container 16, where it deposits the sanding sheet.
