The moving carriage (9) carries at least one welding tool (16, 17) on a compound slide rest (12-14). The moving carriage (9) is freely moved by a distance sensor (23) along a tool profile depending on the machining operation to be carried out, and the compound slide rest allows the moving carriage to move vertically and across the direction of advance. This welding device may be used independently of the power supply system of a manufacturing zone.
Description
PCTIEP 97I04994 2 Amended Sheet The invention teaches that this object can be accomplished by the features disclosed in the characterizing portion of Claim 1.
In a configuration of a welding device as claimed by the invention, a processing device is created that can be used independently of an external energy supply, and can be used in any desired location to which it can be moved by guide devices laid in the floor.
It is controlled exclusively be devices that are associated with the workpiece to be processed. The processing device is thereby equipped with a processing unit with the processing tools required for the work process to be carried out, whereby at (east one processing unit is mounted on a carriage on a guide support) and can be adjusted at least in the vertical and horizontal direction. It is thereby possible to work on parts of workpieces that run at least essentially parallel or perpendicular to the guide support, whereby the workpieces can also tie inclined or uneven within the range of the horizontal adjustability of the guide support. To work on parts of the workpiece that -extend in the horizontal direction, the advance of the activated processing unit is executed along the part of the workpiece to be processed by a correspondingly controlled forward movement. The processing device, which operates self sufficiently, thereby makes it possible to adjust the processing unit mounted on it in a coordinate system in the x: direction as well as in the y and z directions. For the automatic position control of the processing unit along the horizontal, vertical or inclined part of the workpiece, there is at least one position sensor device that mechanically or optically scans the profile of the portion of the workpiece to be processed, and the processing unit then tracks this profile by adjusting the guide support and/or the carriage.
For the self sufficient operation of the processing device, an internal combustion engine, e.g. one operated with a fuel gas, can also be installed on the carriage, with an electric generator connected to it, from which the energy required for the operation and the control of the work processes can be taken. It is thereby not necessary to have electrical connecting cables to tap electrical energy from the electrical power grid; so that the level on which the processing device rolls and on which the workpiece stands remains freely accessible for other uses. Because the respective processing unit must also be controlled along the three unit then tracks this profile by adjusting the guide support and/or the For the self sufficient operation of the processing device, internal combustion engine, e.g. one operated with a fuel gas, can al a installed on the carriage, with an electric generator connected to it) fr ich the energy required for the operation and the control of the work pr ses can be taken. It is thereby not necessary to have electrical conne cables to tap electrical energy from the electrical power grid, so that evel on which the processing device rolls and on which the stands remains freely accessible for other uses. Because the respective coordinates of the workpiece, the wheels of the carriage can also be rubber-tired) and as a result of the realization of a steerable axle) during the advance movement of the carriage) the guidance parallel to the workpiece is satisfactorily ensured by a distance sensor.
Uneven spots in the floor on which the carriage is traveling and resulting changes in the inclination of the carriage or guide support can therefore be compensated by means of a tactile contour sensor that is part of the processing unit. Guide rails that are oriented with respect to the workpiece to be processed, and on which the processing unit can be moved along the workpiece, are therefore no longer necessary.
At (east one welding tool is located on the guide support. As an additional processing unit, a weld grinding tool can be located on the guide support, and after the welding process proper has been completed, it can grind the weld seam flat so that it is plane with respect to the surrounding sheet metal. When aluminum is being welded, it is thereby appropriate to accompany the welding tool with a brushing tool which, during the process of welding aluminum, travels ahead of the welding tool and mechanically brushes away any oxide layers from the weld seam, to prevent defects in the weld seam. It is also possible, however, that the grinding tool that is fastened to a revolver head together with the welding tool can be provided with a brush head that is used before the welding process, and the weld seams can be brushed in a controlled manner using the contour sensor.
The processing unit, which may if necessary carry a plurality of processing tools on a single revolver head, the axis of rotation of which lies parallel in the horizontal direction to the principal direction of travel of the carriage, preferably sits on a cross slide rest that can be displaced horizontally at right angles to the principal direction of travel of the carriage of a compound slide rest, the height of which can be adjusted on a guide column of the guide support. The position of the compound slide rest as well as the advance of the frame are thereby controlled as a function of the scanning position of a tactile or optical contour sensor. The welding tool can thereby be associated with a suitable contour sensor which scans the weld joint as long as it is still open. The brush or grinding tool can have its own sensor, which can sit in the open weld seam or to the side of the area of the workpiece currently being processed, and control a grinding of the weld seam down to the level of the uninfluenced side wall area of the workpiece. The tactile or optical sensors) can thereby be realized in the form of a joystick control unit, the control lever of which acts as a mechanical pin that scans the area of the tool lsic - should be "woikpiece "J to be processed, and the position sensor of which generates control signals for the adjustment of the guide support andlor of the forward motion of the carriage.
The invention is explained in greater detail below with reference to the accompanying schematic perspective drawing of the device.
A railway car body that consists of a plurality of wall elements 2 to be jointed together and supported by a plurality of support pieces 3 stands on a quasi-plane floor formed by the floor of an industrial building, Fixed in position on support pieces 3, underneath a vertical long-side facade consisting of a plurality of wall elements 2 placed one next to the other is a metal or current-conducting guide rail 4 that acts as a batten, which extends in the longitudinal direction of the car body parallel to the plane of the wall elements 2 forming the longitudinal side wall. The guide rail 4 is thereby connected to the metal structure of the car body by means of flexible electrical conductors. Between the wall elements standing in a vertical plane and arranged one next to another, and also extending at least to the roof wall element 2.1 and the frame 2.2, there are joints 6, by means of which the wall elements 2, 2.1 and 2.2 are to be firmly and permanently connected to one another by welding. It may be appropriate to brush the joint 6 before the welding and to grind the weld seams flat after the welding.
To be able to pertorm such processing steps automatically, the car body has a processing device that has a carriage 9 mounted on wheels 7, 8 that do not run on rails. On the carriage 9 there is an at least largely encapsulated propulsion and control unit 10, in which are installed an electrical generator with a gas-powered engine connected to it, as well as various auxiliary devices such as exhaust systems and gas bottles, as well as electrical and hydraulic propulsion and control means for the self sufficient operation of the processing device. At least one axle of the wheels 7, 8 or a pair of wheels 7 is mounted on the carriage 9 so that it can be steered and can be actively steered by means of a steering control device 11 via the control unit 10. The wheel pair 8, on the other hand) can be propelled and controlled by means of the control unit 10 for the movement of the carriage in the forward or reverse direction of travel.
On the carriage 9 is a guide support that is formed from a vertical guide column 12, a compou nd slide rest 13 mounted on it, the height of which can be adjusted, and an integrated drive unit and a cross slide rest that can be displaced horizontally at right angles to the prinapal direction of travel of the carriage 9. On the end closer to the wall elements 2, the cross slide rest 14 has a processing unit 15 that comprises a revolver head disc, to which a welding tool 16 and, offset by approximately 90~, a grinding or brushing unit with a grinding or brush roller 17 are attached. Instead of a combination) however, the processing unit can also have separate processing tools for grinding and brushing. The revolver head disc is thereby mounted in particular so that it can rotate .around a horizontal axis 18 that lies in the principal direction of travel of the carriage 9 with respect to the cross slide rest 14 on the guide support 12-14.
So that the welding tool 16 can be guided along a weld seam joint 6 without manual intervention) the processing unit 15 has a position sensor unit 19. This position sensor unit can work like a joystick control device, and can have a tracer pin 20 mounted so that it moves in a circular motion and at right angles to its longitudinal direction) i.e. in the manner of a ball-and-socket joint.
To produce a weld seam like the one indicated at 6.1, an electrical sliding contact 22 is mounted on the carriage 9 and is positioned by a spring 21 in sliding contact with the guide rail 4 that acts as the welding current return. The sliding contact 22 is connected to the electrical welding power supply of the welding device.
Coupled to the sliding contact is a distance sensor 23 which measures the distance from the guide rail 4 that acts as a mechanical directional rail. For the distance measurement, a mechanical measuring tape 24 is provided, which is held on its free end in the rolling position on the guide rail 4 by means of the sliding contact 22, and which generates a varying control signal in the distance sensor 23 according to its extracted position. The control signal steers the wheel pair 7 so that the distance between the carriage 9 and the guide rail 4 remains at least approximately constant.
To execute the vertical weld seam 6. 9 , the propulsion and control unit 10 is activated and the processing device as a whole, with the sliding contact 22 in contact with the guide rail 4, is moved toward the corresponding weld joint seam 6, into which the tracer pin 20 falls. After the welding current is turned on and the welding process is ignited automatically, the welding material is fed automatically as the compound slide rest 13 is moved along the weld seam joint 6. The position sensor unit 19, as a function of the position of the tracer pin 20, emits a control signal to a control unit for the compound slide rest 13, which keeps the compound slide rest 13 and thus the welding tool 16 at the proper welding discharge from the corresponding weld seam joint 6, and thereby effects the vertical adjustment of the compound slide rest 13 for the optimal welding process. Horizontal changes in the distance of the welding tool 16 from the weld seam 6 can thereby be compensated by forward or backward movements of the carriage parallel to the guide rail 4 or mechanically, while the distance of the welding tool from the weld seam is kept approximately constant by means of the position sensor 19 by a horizontal displacement of the cross slide rest 14.
Alternatively or in addition, the distance of the welding tool from the weld can also be set to the optimum value as a function of the welding current.
If the weld seam to be executed runs horizontally, during the welding process the carriage 9 is propelled in the direction of the weld seam by means of a motor at an advance speed that corresponds to the welding process. The sliding contact 22 thereby maintains the welding current return over the distance traveled) and the distance sensor 23 controls the steering device 11 so that the distance from the guide rail 4 is kept as constant as possible. Deviations of the weld seam joint 6 are then once again detected by the position sensor 19) the tracer pin 20 of which travels ahead of the wire electrode of the welding tool 16 in the open weld seam joint 6. For this purpose, the position sensor 19 is moved as appropriate. The control signal from the position sensor 19 then effects a corresponding correction in the height of the compound slide rest 13 on the guide column 12, as well as a correction of the welding tool 16 with respect to the weld seam joint 6 by means of~ the cross slide rest 14. The wheels 7, 8 and the corresponding wheel pairs are thereby not connected to the rails, and are in particular provided with rubber or elastomer tires, which run unguided along the level 1, like those of an automotive vehicle. Changes in position that result from uneven spots in the plane 1 are thereby also detected immediately by means of the position sensors, and the correction is made as the compound slide rest 13 is controlled by the position sensor 19 and the drive device of the carriage, based on the deviation detected by the distance sensor 23) in effectively the opposite direction. Horizontal deviations from the specified distance detected by the position sensor 19 therefore also have an effect on the vertical drive of the cross slide rest 14) and vertical deviations in the distance from the specified path of the weld joint in question are compensated for by the compound slide rest 13. The distance sensor 23, by acting on the steering device 71, thereby ensures that a specified lateral distance from the wall elements 2 and/or the corresponding weld seam joints 6 is maintained. The distance sensor 23 is thereby provided in the vicinity of the shortest connection between the guide column 12 and the guide rail 4, so that with a specified diagonal position of the longitudinal axis of the carriage with respect to the longitudinal axis of the guide rail, the smallest possible deviations from the specified distance can be achieved.
When a processing device is constructed and controlled as claimed by the invention, by interacting with the components to be welded, weld seams and the processes (brushing, grinding) that precede and follow them can be performed without manual intervention, and weld seams can thereby be executed in the vertical or horizontal direction) as well as in a diagonal direction) whereby the processing device can be self sufficient and, as a guide plane, can use the plane that is also associated with the workpiece to be processed.
In a configuration of a welding device as claimed by the invention, a processing device is created that can be used independently of an external energy supply, and can be used in any desired location to which it can be moved by guide devices laid in the floor.
It is controlled exclusively be devices that are associated with the workpiece to be processed. The processing device is thereby equipped with a processing unit with the processing tools required for the work process to be carried out, whereby at (east one processing unit is mounted on a carriage on a guide support) and can be adjusted at least in the vertical and horizontal direction. It is thereby possible to work on parts of workpieces that run at least essentially parallel or perpendicular to the guide support, whereby the workpieces can also tie inclined or uneven within the range of the horizontal adjustability of the guide support. To work on parts of the workpiece that -extend in the horizontal direction, the advance of the activated processing unit is executed along the part of the workpiece to be processed by a correspondingly controlled forward movement. The processing device, which operates self sufficiently, thereby makes it possible to adjust the processing unit mounted on it in a coordinate system in the x: direction as well as in the y and z directions. For the automatic position control of the processing unit along the horizontal, vertical or inclined part of the workpiece, there is at least one position sensor device that mechanically or optically scans the profile of the portion of the workpiece to be processed, and the processing unit then tracks this profile by adjusting the guide support and/or the carriage.
For the self sufficient operation of the processing device, an internal combustion engine, e.g. one operated with a fuel gas, can also be installed on the carriage, with an electric generator connected to it, from which the energy required for the operation and the control of the work processes can be taken. It is thereby not necessary to have electrical connecting cables to tap electrical energy from the electrical power grid; so that the level on which the processing device rolls and on which the workpiece stands remains freely accessible for other uses.

The invention is explained in greater detail below with reference to the accompanying schematic perspective drawing of the device.
A railway car body that consists of a plurality of wall elements 2 to be jointed together and supported by a plurality of support pieces 3 stands on a quasi-plane floor formed by the floor of an industrial building, Fixed in position on support pieces 3, underneath a vertical long-side facade consisting of a plurality of wall elements 2 placed one next to the other is a metal or current-conducting guide rail 4 that acts as a batten, which extends in the longitudinal direction of the car body parallel to the plane of the wall elements 2 forming the longitudinal side wall. The guide rail 4 is thereby connected to the metal structure of the car body by means of flexible electrical conductors. Between the wall elements standing in a vertical plane and arranged one next to another, and also extending at least to the roof wall element 2.1 and the frame 2.2, there are joints 6, by means of which the wall elements 2, 2.1 and 2.2 are to be firmly and permanently connected to one another by welding. It may be appropriate to brush the joint 6 before the welding and to grind the weld seams flat after the welding.
To be able to pertorm such processing steps automatically, the car body has a processing device that has a carriage 9 mounted on wheels 7, 8 that do not run on rails. On the carriage 9 there is an at least largely encapsulated propulsion and control unit 10, in which are installed an electrical generator with a gas-powered engine connected to it, as well as various auxiliary devices such as exhaust systems and gas bottles, as well as electrical and hydraulic propulsion and control means for the self sufficient operation of the processing device. At least one axle of the wheels 7, 8 or a pair of wheels 7 is mounted on the carriage 9 so that it can be steered and can be actively steered by means of a steering control device 11 via the control unit 10. The wheel pair 8, on the other hand) can be propelled and controlled by means of the control unit 10 for the movement of the carriage in the forward or reverse direction of travel.
On the carriage 9 is a guide support that is formed from a vertical guide column 12, a compou nd slide rest 13 mounted on it, the height of which can be adjusted, and an integrated drive unit and a cross slide rest that can be displaced horizontally at right angles to the prinapal direction of travel of the carriage 9. On the end closer to the wall elements 2, the cross slide rest 14 has a processing unit 15 that comprises a revolver head disc, to which a welding tool 16 and, offset by approximately 90~, a grinding or brushing unit with a grinding or brush roller 17 are attached. Instead of a combination) however, the processing unit can also have separate processing tools for grinding and brushing. The revolver head disc is thereby mounted in particular so that it can rotate .around a horizontal axis 18 that lies in the principal direction of travel of the carriage 9 with respect to the cross slide rest 14 on the guide support 12-14.
So that the welding tool 16 can be guided along a weld seam joint 6 without manual intervention) the processing unit 15 has a position sensor unit 19. This position sensor unit can work like a joystick control device, and can have a tracer pin 20 mounted so that it moves in a circular motion and at right angles to its longitudinal direction) i.e. in the manner of a ball-and-socket joint.
To produce a weld seam like the one indicated at 6.1, an electrical sliding contact 22 is mounted on the carriage 9 and is positioned by a spring 21 in sliding contact with the guide rail 4 that acts as the welding current return. The sliding contact 22 is connected to the electrical welding power supply of the welding device.
Coupled to the sliding contact is a distance sensor 23 which measures the distance from the guide rail 4 that acts as a mechanical directional rail. For the distance measurement, a mechanical measuring tape 24 is provided, which is held on its free end in the rolling position on the guide rail 4 by means of the sliding contact 22, and which generates a varying control signal in the distance sensor 23 according to its extracted position. The control signal steers the wheel pair 7 so that the distance between the carriage 9 and the guide rail 4 remains at least approximately constant.
To execute the vertical weld seam 6. 9 , the propulsion and control unit 10 is activated and the processing device as a whole, with the sliding contact 22 in contact with the guide rail 4, is moved toward the corresponding weld joint seam 6, into which the tracer pin 20 falls. After the welding current is turned on and the welding process is ignited automatically, the welding material is fed automatically as the compound slide rest 13 is moved along the weld seam joint 6. The position sensor unit 19, as a function of the position of the tracer pin 20, emits a control signal to a control unit for the compound slide rest 13, which keeps the compound slide rest 13 and thus the welding tool 16 at the proper welding discharge from the corresponding weld seam joint 6, and thereby effects the vertical adjustment of the compound slide rest 13 for the optimal welding process. Horizontal changes in the distance of the welding tool 16 from the weld seam 6 can thereby be compensated by forward or backward movements of the carriage parallel to the guide rail 4 or mechanically, while the distance of the welding tool from the weld seam is kept approximately constant by means of the position sensor 19 by a horizontal displacement of the cross slide rest 14.
Alternatively or in addition, the distance of the welding tool from the weld can also be set to the optimum value as a function of the welding current.
If the weld seam to be executed runs horizontally, during the welding process the carriage 9 is propelled in the direction of the weld seam by means of a motor at an advance speed that corresponds to the welding process. The sliding contact 22 thereby maintains the welding current return over the distance traveled) and the distance sensor 23 controls the steering device 11 so that the distance from the guide rail 4 is kept as constant as possible. Deviations of the weld seam joint 6 are then once again detected by the position sensor 19) the tracer pin 20 of which travels ahead of the wire electrode of the welding tool 16 in the open weld seam joint 6. For this purpose, the position sensor 19 is moved as appropriate. The control signal from the position sensor 19 then effects a corresponding correction in the height of the compound slide rest 13 on the guide column 12, as well as a correction of the welding tool 16 with respect to the weld seam joint 6 by means of~ the cross slide rest 14. The wheels 7, 8 and the corresponding wheel pairs are thereby not connected to the rails, and are in particular provided with rubber or elastomer tires, which run unguided along the level 1, like those of an automotive vehicle. Changes in position that result from uneven spots in the plane 1 are thereby also detected immediately by means of the position sensors, and the correction is made as the compound slide rest 13 is controlled by the position sensor 19 and the drive device of the carriage, based on the deviation detected by the distance sensor 23) in effectively the opposite direction. Horizontal deviations from the specified distance detected by the position sensor 19 therefore also have an effect on the vertical drive of the cross slide rest 14) and vertical deviations in the distance from the specified path of the weld joint in question are compensated for by the compound slide rest 13. The distance sensor 23, by acting on the steering device 71, thereby ensures that a specified lateral distance from the wall elements 2 and/or the corresponding weld seam joints 6 is maintained. The distance sensor 23 is thereby provided in the vicinity of the shortest connection between the guide column 12 and the guide rail 4, so that with a specified diagonal position of the longitudinal axis of the carriage with respect to the longitudinal axis of the guide rail, the smallest possible deviations from the specified distance can be achieved.
When a processing device is constructed and controlled as claimed by the invention, by interacting with the components to be welded, weld seams and the processes (brushing, grinding) that precede and follow them can be performed without manual intervention, and weld seams can thereby be executed in the vertical or horizontal direction) as well as in a diagonal direction) whereby the processing device can be self sufficient and, as a guide plane, can use the plane that is also associated with the workpiece to be processed.
