Definitions

  • the invention relates to a grinding machine for grinding a metallic surface of a workpiece, wherein the grinding machine has at least one grinding unit and at least one conveyor belt for transporting the workpiece through the grinding machine.
  • the grinding unit may have disc brushes or brush rollers or circulating abrasives, such as abrasive belts or abrasive papers have. Orbital sander can also be used.
  • Grinding machines are used for example for rounding and deburring of punching or cutting edges of metal workpieces. But also for finishing and beautifying metallic surfaces, for example in the production of brushed steel surfaces or brushed aluminum surfaces are used accordingly by grinding machines.
  • generators are generally used, which have a suction device.
  • the conveyor belt is not equipped with fastening means with which the workpiece to be machined is fixed on the conveyor belt. Instead, the suction device is present, applied by a resting on the conveyor belt workpiece with negative pressure and so can be held on the conveyor belt.
  • the invention is therefore based on the object to further develop a grinding machine so that even different metals can be processed easily with a single grinding machine.
  • the invention solves the problem set by a generic grinding machine according to the preamble of claim 1, which is characterized in that the grinding machine has a suction chamber, which is arranged below the conveyor belt and has a counter to the horizontal inclined bottom.
  • the grinding machine has a suction device, by means of which a workpiece lying on the conveyor belt can be subjected to a negative pressure, wherein the suction chamber is part of the suction device.
  • the suction chamber is carried out as a rule as part of the suction device, but can also be used in the context of the present invention without the possibility to pressurize it with negative pressure.
  • the abrasive chips or sanding dust to be removed are then led out of the grinding area of the sanding machine by the inclined bottom and the dead weight of the chips or the satee, and can be easily removed.
  • a suction chamber arranged below the conveyor belt is preferably arranged only below the part of the conveyor belt on which the workpieces are transported by the grinding machine.
  • the conveyor belt is usually a revolving endless belt, which forms a closed contour.
  • the suction chamber disposed within this contour as directly as possible below the conveyor belt.
  • the bottom of the suction chamber with the horizontal at an angle of at least 5 °, preferably at least 10 °, more preferably at least 15 °, and at most 30 °, preferably at most 25 °, more preferably at most 20 °.
  • the bottom of the suction chamber is inclined perpendicular to the transport direction, along which the workpiece can be transported by the conveyor belt. This means that the workpiece is transported along the transport direction and the inclination extends to the right or left thereof.
  • Abrasive dust and grinding chips which are created by machining the surface of the workpiece with the grinding unit, can pass through existing in the conveyor belt holes or openings in the suction chamber, from where they can be sucked. This is further simplified and made more efficient by the inclined bottom of the suction chamber. In this way, the remaining contamination of the grinding machine with grinding dust and grinding chips made of a metal is significantly reduced or ideally completely avoided.
  • the suction chamber is connected to the lower end of the floor with a suction device or connectable. Due to this, grinding dust and grinding chips can be sucked out of the suction chamber.
  • the bottom of the suction chamber is thus inclined to this suction device.
  • the conveyor belt is coated with an anti-adhesion coating.
  • the inside of the suction chamber, but at least the bottom of the suction chamber is coated with an anti-adhesion coating.
  • a polymer or a mixture of several polymers for the anti-adhesion coating has been found. This also causes the residual contamination and contamination of the conveyor belt and the suction device, in particular the suction, reduced and thus reduced the cleaning effort.
  • the bottom of the suction chamber can also be excited mechanically, that is, in particular, be set in vibration.
  • These can be regular oscillations such as sound waves or individual regularly or irregularly recurring shocks.
  • chips or dust which has settled at the bottom of the suction, be moved so that it collects and removed, for example, can be sucked.
  • the grinding machine has a plurality of conveyor belts and a plurality of suction devices, wherein the suction devices each have a suction chamber with an inclined bottom.
  • the grinding machine is equipped with a plurality of grinding aggregates, which may be different or identical, it has proved to be advantageous if each of the aggregates is arranged in a grinding machine module which can be exchanged separately or removed from the grinding machine separately and from the other modules .
  • each of the modules which may for example have one or two grinding units, have their own conveyor belt, which is only responsible for the transport of the workpiece within the grinding machine module.
  • a carryover of grinding chips or grinding dust is prevented by an excessively long conveyor belt through the entire grinding machine and also allows easy interchangeability and expandability of the individual units and modules, for example, for cleaning, maintenance or replacement purposes.
  • the at least one conveyor belt can be replaced without the grinding unit having to be removed.
  • a surrounding the grinding units housing the grinding machine can be opened. After any existing supports are removed, which hold the transport table, which has the conveyor belt in position, have been removed, the conveyor belt can be removed.
  • a clamping device which is responsible for a sufficient tension on the conveyor belt, be solved. The sanding belt can then be easily removed without it being necessary would be to disassemble the grinder completely or to remove a grinding unit or grinding module from the grinder.
  • the grinding machine has a housing in which the grinding unit is arranged, wherein the conveyor belt is removable from the grinding machine, wherein the grinding unit and / or the grinding table does not have to be removed from the grinding machine.
  • the conveyor belt is not exposed to excessive loads, so that a change of the conveyor belt in the operation of a grinding machine is a rarely be performed maintenance action.
  • the grinding table and possibly additionally the grinding unit, ie the actual abrasive must be removed from the housing of the grinding machine. Then the grinding table has to be disassembled so far that the conveyor belt becomes accessible.
  • This embodiment of the grinding machine now makes it possible to change the conveyor belt and to remove it from the grinding machine without removing the grinding unit and / or the grinding table from the grinding machine.
  • the change of the conveyor belt is greatly simplified. If, for example, metallic surfaces of different metals are to be ground in succession, instead of the often expensive and time-consuming cleaning of a conveyor belt, the respective grinding belt can now be exchanged so that particles of the grinding dust or grinding chips adhering to the grinding belt no longer have to be removed.
  • different conveyor belts can be provided for different metals, which can be used in the grinding machine depending on the desired type of metal that is to be ground.
  • a removed conveyor belt can be cleaned with the required care to be ready for later use with another type of metal. With the embodiment of the grinding machine according to the invention, this no longer has the consequence that during this time of cleaning the conveyor belt, it is no longer possible to grind workpieces. Rather, one of the conveyor belts can be cleaned while another conveyor belt is used in the grinding machine.
  • the housing has an opening flap, which can be brought into an open state and a closed state, wherein the conveyor belt is accessible when the opening flap is in the open state.
  • the opening flap is advantageously a door or a double door, which is arranged so that the housing can be opened easily.
  • the grinding table is attached to at least one releasably mounted support. Especially with larger grinding machines or grinding modules, which optionally have more than one grinding unit, it is advantageous to secure the grinding table on both sides of the conveyor belt by at least one support.
  • the support is as easy as possible to solve. This can be achieved, for example, by simple screw connections, which are released for changing the conveyor belt.
  • the number, positioning and method of attachment and mounting of the detachably mounted supports depends on the size of the grinding machine, the number of grinding units used and the type of grinding, as this significantly determines how much the on the workpiece and thus on the conveyor belt is applied pressure exerted by the grinding units.
  • the grinding machine has a suction device, by means of which a workpiece lying on the conveyor belt can be subjected to a negative pressure.
  • a holding force on the workpiece is increased, so that even with larger forces applied by the grinding unit to the workpiece forces the workpiece can not slip along the conveyor belt or move.
  • the grinding machine has a plurality of grinding modules, each having at least one grinding unit and a conveyor belt.
  • each grinding module is advantageously removable separately from the grinding machine and, for example, replaced by another module.
  • Each module has in a preferred embodiment at least one opening flap, more preferably a door through which a part of the housing, which belongs to the module, can be opened, whereby the conveyor belt is accessible.
  • the grinding machine has a grinding tool or grinding unit with at least one brush with abrasive bristles and a planning unit.
  • a planning unit is a functional unit within the grinding machine which, for example, in a special operating mode of the grinding machine, ensures that the concentricity and the straightness of the grinding tool, in particular a brush roller, are restored.
  • This particular mode of operation may, for example, be in the form of a predetermined program stored in an electronic data storage which may be retrieved and executed by an electronic controller of the grinding machine. It is therefore only very rarely necessary with a grinding machine according to the invention to remove the actual grinding tool, in particular the brush roller, from the grinding machine. This is only necessary if the brush roller is to be completely replaced.
  • the special operating mode of the grinding machine is triggered manually, for example.
  • the concentricity of the concentricity and the straightness of the brush roller are restored. This can be done within a few minutes, so that after the expiration of this period, when the program stored, for example, in the electronic data memory has been run through, the grinding machine is fully operational again and provides almost optimal grinding results.
  • the planning unit has at least one leveling tool for shortening at least a portion of the abrasive bristles.
  • the leveling tool can for example consist of a plurality of cutting elements, which are arranged, for example, across the width of the grinding tool and thus simultaneously can shorten the abrasive bristles of the abrasive over the entire width.
  • the grading tool can be designed as a large cutting element, for example, a blade extending across the entire width or scissors or consist of a plurality of different juxtaposed individual elements, then different lengths of abrasive bristles can be adjusted at different points of the grinding tool.
  • the leveling tool is arranged displaceably in a direction perpendicular to the transport direction.
  • the leveling tool itself can then be spatially small and thus formed with a relatively low inherent weight, so that the expenditure on equipment which is to be operated in such a grinding machine for the planing unit is significantly reduced.
  • the planning unit in a direction perpendicular to the transport direction ie in a grinding machine from left to right and vice versa is movable and can be accessed at any point across the width of the brush roller. Since the brush roller is set in rotation anyway, all bristles of the brush roller can be shortened to the desired length in this way.
  • the at least one grinding tool and / or the leveling tool is arranged vertically adjustable.
  • the grinding tool can be adjusted in height in a large number of known grinding machines in order to be able to make the distance between the grinding tool and the transport device variable and thus to be adjustable to workpieces of different thicknesses.
  • the leveling tool is not height-adjustable relative to the transport device, so that a height adjustment of the grinding tool at the same time has a change in the distance between the grinding tool and the leveling tool result.
  • the leveling tool can be made adjustable in height, as long as the grinding tool and leveling tool are independently adjustable in height. Only in this way, the distance can be changed and so the length to which the abrasive bristles are shortened by the leveling tool set.
  • the grinding tool has a plurality of disc brushes, which rotate along a circulation contour, wherein the at least one leveling tool is arranged next to the transport device.
  • the arrangement of the leveling tool above this brush roller has been found to be advantageous because the bristles in the rotating brush anyway in this direction.
  • disc brushes are used, the situation is different.
  • all abrasive bristles are usually directed towards the workpiece and the axis of rotation about which the disc brush rotates or pivots is perpendicular to the transport plane of the transport device.
  • the plate brushes which also rotate on a circulation contour in addition to the rotation about its axis of rotation, are also moved in a region next to the transport device, so that there are portions of the circulation contour in which the disc brushes and the abrasive bristles of the disc brushes can not come into contact with a workpiece which is located on the transport device.
  • the at least one leveling tool can be arranged in a particularly simple and space-saving and therefore technically complicated manner.
  • a plurality of leveling tools are arranged on both sides of the transport device in this case.
  • the grinding machine has a measuring device for measuring the length of the abrasive bristles. This can be done, for example, contactless, in particular via light barriers or by pressure or touch sensors that measure whether certain points still come into contact with the rotating abrasive bristles. Again, it has proved to be advantageous if the measuring device is set up to measure the length of the brushes at different points of the grinding tool. This means in particular that the length of the abrasive bristles can be measured at different positions across the width of the grinding tool.
  • the grinding machine also has an electrical control adapted to bring the leveling tool into engagement with the abrasive bristles and thus to shorten the bristles when a difference in length between different bristles exceeds a predetermined limit.
  • the electrical controller may automatically turn on the operating mode of leveling Force and so ensure that the grading tool is brought into engagement with the respective abrasive bristles, so that the difference in length between the individual bristles is reduced or brought to the desired level.
  • the electrical control may also trigger a display or alarm device so that an operator of the grinding machine recognizes that cutting the abrasive bristles is necessary.
  • the predetermined limit depends on the length of the brushes.
  • the brushes already relatively short as they multiply, for example shortened, it may be useful to select the predetermined limit relatively small in order to achieve that a relative change in length remains as small as possible.
  • the length of the brushes is still relatively large, for example in the case of a brush roller inserted freshly into the grinding machine, it is quite possible for larger differences in length to be tolerable.
  • the grinding machine has a device for determining a radius of a contour of an object with at least niksegmentförmigem cross section, the two contact surfaces for applying the object and at least one Messschiebeetzweis, wherein the contact surfaces are arranged at a right angle to each other and the caliper along an angle bisector of this right angle slidably arranged such that the caliper is displaceable by the object is applied to the two contact surfaces.
  • the device has a measuring device for measuring the distance by which the caliper is displaced when the object is applied to the two contact surfaces.
  • the device has an electrical control which is set up to determine the radius from the measured distance.
  • the device preferably has a display device which is set up to indicate the radius and / or the distance by which the caliper has been displaced.
  • This embodiment is based on the finding that an object with a circular segment-shaped or circular cross-section, which is arranged with the contour of this cross-section at the two arranged at a right angle bearing surface, the caliper shifts.
  • the circle-segment-shaped or circular cross-section can be approximated, at least mentally, by a circle having a radius which is to be determined by the device.
  • this circle forms the incircle or inner circle into a square whose one corner is formed by the point at which the two abutment surfaces abut each other.
  • This square can be mentally described by a perimeter or outer circle, whose center is therefore located in the center of the Innnikes and passing through the contact point, so the "corner" of the two contact surfaces.
  • the statements about circles, squares or points in each case refer to the cross section through the article, which is inserted into the device according to an embodiment of the present invention.
  • the difference between the radius of the inscribed circle or inner circle and the radius of the circumference or outer circle corresponds exactly to the distance by which the caliper still protrudes from the corner formed by the two contact surfaces. If it is known how far the calliper protrudes from this corner without an inserted object, it is easy to calculate how big the difference between the radius of the inner circle and the radius of the outer circle is. In this way, the radius of the inner circle can be determined, which corresponds to the radius to be determined.
  • the device is arranged to determine the radius of an edge of the workpiece. This is advantageously done after the workpiece has run along the actual grinding tool and has interacted with it, thus after the grinding process. Due to the very simple device for measuring the radius can be determined in a particularly simple, yet safe and reproducible manner, whether the desired grinding result has been achieved and the radius of the edge of the workpiece meets the legal or other requirements. For this purpose, only the edge of the workpiece whose radius is to be measured, must be applied to the two contact surfaces of the device. The radius of the edge can be determined in a particularly simple way by the way by which the caliper is displaced during this application.
  • the grinding machine has an actuator that moves the device to the desired edge of the workpiece.
  • the grinding machine has a position detection device and / or an orientation detection device with which the position and / or orientation of the workpiece can be recognized on a transport device of the grinding machine.
  • the actuator which may be, for example, a robot arm, particularly preferably a multi-jointed robot arm can, the device approaches and applies exactly to the desired location of the workpiece to be checked and the required edge.
  • a radius determined by the device is used as control parameter or controlled variable in the electrical control of the grinding machine.
  • the workpiece can be performed, for example, again by the grinding machine or be marked as rejects or nach.
  • the specific radius is too small, ie the abrasion caused by the grinding machine is insufficient to achieve the desired target value, to increase the contact pressure of the grinding tool to the surface of the workpiece and thus at the following Workpieces to achieve a larger grinding abrasion and thus a larger radius of the edge. This is particularly useful when several workpieces, especially many workpieces to be processed and ground one after the other, which have a surface made of the same material.
  • the grinding machine has an imbalance measuring device for measuring an imbalance of the grinding tool. Also in this way it can be determined whether some or all of the abrasive bristles must be shortened.
  • FIG. 1 shows a transport table 1 for a grinding machine according to a first embodiment of the present invention. It can be seen a conveyor belt 2, which is guided over deflecting rollers 4 and a tensioning device 6. The conveyor belt is covered by a in FIG. 1 Motor not shown, and can move a workpiece, not shown, which is located on the conveyor belt 2, along a transport direction T.
  • transport table 1 stands on supports 8, which also support a not shown grinding unit.
  • feet 10 are present, which are on suspensions 12 and on which a grinding unit frame is arranged with a grinding unit.
  • a suction chamber 14 which has an inclined bottom 16 whose inclination is perpendicular to the transport direction T.
  • the bottom 16 is formed inclined along a direction perpendicular to the plane of the drawing.
  • the suction chamber 14 is within the meaning of the present invention below the conveyor belt 2, even if a return 18 of the conveyor belt 2 is located below the suction chamber 14.
  • FIG. 2 shows the schematic view of the suction chamber 14. It can be seen the inclined bottom 16 whose inclination in FIG. 2 from left to right and thus perpendicular to the transport direction T runs.
  • An upper side 20 of the suction chamber 14 is advantageously designed to be open in order to be able to transfer a negative pressure to be established within the suction chamber 14 to the conveyor belt 2 running above it and thus to a workpiece located thereon.
  • FIG. 3 shows another view of a suction chamber 14 with the inclined bottom 16. It can be seen that a height of the suction chamber 14 in the central region is greatest and decreases in edge regions 22. Overall, however, the bottom 16 is in FIG. 3 tilted backwards.
