Description

Technical FieldThe invention relates to a device which can be used for positioning a component, preferably in a wood-working machine. Furthermore, the invention relates to a method for positioning a component, preferably in a tool store or working region of a machining device, in particular a wood-working machine.Prior ArtFor positioning components, such as workpieces or machining units, in particular in wood-machining machines, a plurality of drives are usually used. The reason for this is that one guide unit together with the drive must be used for each direction of movement of the component to be positioned. This means, for example, that when the component to be positioned is to be rotated, an additional rotary drive with corresponding guidance is required. Furthermore, the position is determined via additional measurement systems.DE 10 2005 007 489 A1 discloses a wood-working machine with at least one linear direct drive, which has a primary part and a secondary part, wherein the primary part and / or secondary part is suitable for guiding or delivering a workpiece and / or for guiding or delivering a tool for working the workpiece. A disadvantage of such wood-working machines is that a linear drive must be used for each direction of movement of the component to be positioned.DE 10 2015 209 618 A1 discloses a device for transferring and / or grouping products, comprising at least one mover, which has at least one permanent magnet, which is connected to the mover, wherein the permanent magnet interacts with at least one coil plane of a drive surface for driving the mover in a particularly contactless manner, wherein the mover is arranged on the drive surface such that it can be displaced and / or rotated in at least two degrees of freedom. A disadvantage of such a transport device is that this device can transport the workpieces via the mover to a horizontal plane but cannot adjust them vertically.DE 10 2021 108 988 A1 discloses a method for processing an object by means of a planar drive system, wherein the planar drive system has at least one stator unit, a stator surface above the stator unit, and at least one rotor having a plurality of magnetic units for generating a rotor magnetic field. A disadvantage of such a method is that the machining units can be adjusted via the runners in a horizontal plane, but not in a vertical plane.The disadvantage of present-day prior art devices and methods is generally that they require a plurality of drives in order to position a component or cannot move the component vertically at all, since they are not suitable to act satisfactorily against the force of gravity of the components to be positioned.SUMMARY OF THE INVENTIONThe object of the invention is to provide a device which, by means of a simplified drive, can position a component quickly, highly dynamically and precisely in a plurality of directions.A component positioning apparatus according to the invention is defined in claim 1. A method of positioning a component according to the invention is defined in claim 9. The dependent claims relate to specific embodiments.The device according to the invention for positioning a component comprises a carrier, a primary part which is provided in the region of the carrier, and a secondary part which is arranged contactless to the primary part, so that a relative movement between the secondary part and the primary part can be carried out in a plurality of directions, for example in one or more planes, in order to adjust and / or fix the component which is to be positioned. The directions may be translatory and / or rotatory.An advantage of the device according to the invention is that at least one primary part and one secondary part are used instead of a plurality of linear motors or a plurality of drives and additional rotary drive in order to adjust and / or fix a component to be positioned. This saves costs and space. Space saving is also effected in the direction of the machine operator and thus also better space conditions are obtained. In addition, parts for fastening a plurality of drives can be dispensed with. Since the position determination can be carried out by means of the secondary part, no additional position determination elements, such as measurement systems, are required. As a result, the assembly effort is lower than in the devices described in the prior art for positioning components.A further advantage of the device according to the invention is that the positioning, including the position determination of the component to be positioned, can be carried out in a highly dynamic manner, at high speed and with high accuracy, because the secondary part can move freely in multiple directions relative to the primary part.Since the secondary part is arranged contactless to the primary part, no wear takes place between the two parts and the secondary part, including the machining unit, can easily be removed and replaced. As a result, the maintenance of the device is particularly quick and simple.In addition, the carrier makes it possible to fasten the primary part, so that the device acts against the force of gravity of the components to be positioned and consequently the secondary part can also adjust the component vertically and / or can carry out a corresponding fixing.The secondary part can move in multiple translatory and / or rotatory directions relative to the primary part. According to one embodiment, the secondary part can be tilted relative to the primary part.According to one embodiment, it is provided that the primary part is fastened to the carrier. However, the secondary part can also be fastened to the carrier.In one embodiment, the component which is to be positioned can be fastened to the secondary part or to the primary part of the device according to the invention, in particular mechanically, pneumatically and / or via magnetic forces.This ensures that the component is seated firmly on the secondary part and that the secondary part or primary part transmits forces and torques precisely and efficiently to the component to be positioned. This is advantageous in particular when the component to be positioned has a high weight or is a machining unit which is intended to machine a workpiece made of a hard material.The component can also be fastened to the secondary part or primary part by other means or methods. These also include chemical methods, such as, for example, the adhesion of the component to the secondary part, which is particularly cost-effective, simple and fast.In one embodiment, the component to be positioned may be mounted on a panel. The plate may allow a cross-guiding system to move.Large components to be positioned can be mounted on the plate while the cross-guide system allows to better support the weight of the components. Thus, large and heavy components can be adjusted. In addition, the cross-guide system offers increased rigidity and stability during the adjustment of the components. Large and heavy components can thus also be adjusted precisely and stably.In one embodiment, the cross-guiding system may comprise cross-guiding carriages.The use of the cross-guiding carriages contributes to the cross-guiding system being compact and loadable.In one embodiment, the secondary part or primary part can have an additional rotating device.If a cross-guiding system is used to guide the movements of the plate on which the component to be positioned is fastened, the secondary part or primary part can, by means of the rotating device, for example a rotating ring, translate the component to be positioned not only along the directions of the rails of the cross-guiding system but also rotate about an axis which runs through the secondary part or primary part. This increases the degrees of freedom in the adjustment and / or fixing of the component to be positioned.In one embodiment, the component to be positioned can be a processing unit which preferably has an additional magnetic field or an additional drive for the translatory movement.If the component to be positioned is a processing unit, the movement of the secondary part or primary part makes it possible to process workpieces and to change tools easily and / or automatically. By means of the additional drive for the translatory movement, for example, the engagement and / or disengagement of tools is made possible.In one embodiment, at least one holding device, in particular at least one suction device, can be fastened to the secondary part or primary part and can be adjusted by the latter. Alternatively, individual holding devices, in particular individual suction devices, can be fastened to one or more secondary parts or one or more primary parts. In this case, the individual holding devices, in particular the individual suction devices, can then be adjusted by the secondary part or by the plurality of secondary parts.The use of the secondary part / the secondary parts and / or the primary part / the primary parts for the positioning of the holding device / the holding devices (in particular the suction device / the suction device) enables a highly dynamic, rapid and precise adjustment of the holding device / the holding devices and consequently a rapid, precise and stable positioning of workpieces. This is particularly advantageous if the workpieces have very different and / or special shapes. When a workpiece having a certain shape arrives, the holding means can be positioned quickly according to the specific shape of the workpiece. In this way, the workpiece can be fixed precisely and stably via the holding devices, so that the distribution of the forces acting on it is also optimum during the machining.In one embodiment, the secondary part can travel from one plane to another plane by an arrangement of the primary parts, or the primary part can travel from one plane to another plane by an arrangement of secondary parts.In this way, the secondary part or the primary part can move freely in a plurality of planes in the space and, for example, a processing unit fastened thereon can be used in a plurality of planes. This facilitates the machining of workpieces even if they have very complicated three-dimensional shapes.The method according to the invention for positioning a component in a tool store or working region of a machining device, in particular a wood-machining machine, comprises positioning a secondary part in the region of a primary part, or positioning a primary part in the region of a secondary part, wherein the primary part and the secondary part are arranged contactless and are movable relative to one another in a plurality of directions, and moving the secondary part, for example in a plane, relative to the primary part and / or moving the primary part relative to the secondary part for the adjustment and / or fixing of the component to be positioned.An advantage of the method according to the invention is that only one primary part and one secondary part are necessary in order to adjust a component to be positioned. This saves parts such as external measuring systems and fastenings of several drives. This reduces costs, space requirements and assembly effort.A further advantage of the method according to the invention is that the positioning including the position determination of the component to be positioned takes place in a highly dynamic manner, at high speed and with high accuracy, because the secondary part can move freely in a plurality of directions.Moreover, since the secondary part is arranged contactless to the primary part, no wear occurs between the two parts and the secondary part, including the machining unit, can easily be removed and replaced. As a result, the maintenance of the device is particularly quick and simple.In one embodiment, the method according to the invention further comprises rotating the secondary part and / or the primary part about an axis running through the secondary part and / or the primary part.This increases the degrees of freedom of the adjustment of the component to be positioned and thus more complex machinings can be carried out on or by the component to be positioned. In addition, the machining unit can be rotated to the operator and the tool change can thus be simplified.In an embodiment for the machining of workpieces, the method according to the invention further comprises generating a rotation of the component to be positioned, which is a machining unit.As a result, more complex machining operations can be carried out via the component to be positioned and a tool change is simplified.In one embodiment, the method according to the invention further comprises fastening the component to be positioned, which is a workpiece, via a holding device, in particular a suction device, which is mounted on a secondary part or primary part, and positioning the workpiece by the movement of the holding device (in particular of the suction device) for the machining in the working region.Thereby, when a workpiece having a certain shape arrives, the holding devices (suckers) can be positioned quickly according to the specific shape of the workpiece. In this way, the workpiece can be fixed precisely and stably via the suction devices, so that the distribution of the forces acting on it is also optimum during the machining.In one embodiment for machining a workpiece arranged in the working region, the method according to the invention further comprises arranging the secondary part which carries the component to be positioned, machining the workpiece by the component to be positioned, which is a machining unit, and returning the secondary part to the ready position.In this way, the secondary part with the machining unit can travel around the workpiece to be machined, while the workpiece is translated in one direction, for example. This enables complex machining with minimal movement of the workpiece. The cycle time of the process is thus reduced and thus the productivity is increased.In one embodiment, the method according to the invention further comprises coordinating a plurality of secondary parts for the machining of a workpiece arranged in the working area.Thereby, machining operations performed via different machining units can be parallelized. Thus, time is saved and, consequently, productivity is increased.The secondary part can move in multiple translatory and / or rotatory directions relative to the primary part. According to one embodiment, the secondary part can be tilted relative to the primary part.Brief Description of the DrawingsFurther features and advantages result from the following description of embodiments with reference to the attached drawings.

The directions may be translatory and / or rotatory.According to the first embodiment, the component 5 to be positioned can be fastened in I to the secondary part 4 I above a plate 6 I. A cross-guide system 7 I can then be mounted on the carrier 2 I for example as in FIG. 1 a, and can preferably have at least one cross-guide carriage. To better support the weight of the component 5 I, to be positioned, the plate 6 I can be mounted on this cross-guiding system 7 I. When the secondary part 4 I then moves in I in the region of the primary part 3, the plate 6 I is consequently translated along the directions of the rails of the cross-guiding system 7 I. As a result, the component 5 to be positioned can be adjusted in I fashion.In addition, FIG. 1 bshows that the secondary part 4 I can have an additional rotating device 8 I, for example a rotating ring. By means of the rotation device 8 I the secondary part 4 I can then not only translate the component 5 I to be positioned along the directions of the rails of the cross-guiding system 7 I, but can also rotate about an axis which runs through the secondary part 4 I.

Via a preferred pneumatic contact, one or more components 5 to be positioned III, for example workpieces, can then be fastened III via the suction devices 9. A plurality of suction devices 9 can be fastened in III on the secondary part 4 in III fashion. The suction devices 9 III are then moved by the secondary part 4 III into the correspondingly desired position in order to adjust and / or fix the component 5 to be positioned in a III manner. Alternatively, individual suction devices 9 III can be accommodated by a secondary part 4 III or a plurality of secondary parts 4 III and moved into the desired position. Thus, a workpiece can be positioned in the working area for machining by the movement of the sucker 9 III, to which it is attached.FIG. 4 shows a fourth embodiment of the device 1 IV. according to the invention. According to the fourth embodiment, the device 1 according to the invention can comprise IV for example a secondary part 4 IV and a plurality of primary parts 3 IV. By a suitable arrangement of the primary parts 3 IV the secondary part 4 can travel IV from one plane, for example horizontally, into another, for example vertically. As a result, a component 5 IV, for example a machining unit, fastened thereon can be used in a plurality of planes.In all embodiments of the device according to the invention, the component to be positioned can preferably be a workpiece, a machining unit such as a motor or a machine. In addition, if the machining unit to be positioned is an electric motor, it can have an additional drive for the translatory movement of the stator along the axis, for example in order to engage and / or disengage a tool.In all embodiments of the device according to the invention, the secondary part can be used not only for adjusting and / or fixing the component to be positioned, but also for applying the translatory and / or rotatory movements for machining with a tool, such as for example with a form milling cutter, standard milling cutter, pre- and fine milling cutter, drawing blades and a joining milling cutter.For the machining of a workpiece arranged in the working area (A), one or more secondary parts can be used.
