Description

[0001] The invention relates to a device for processing workpieces according to the preamble of claim 1. Furthermore, the invention relates to a method for picking up or placing down an aggregate for process automation according to the preamble of claim 12.

[0002] Devices of this type are used particularly in industrial prefabricated house construction. In industrial prefabricated house construction, components, especially building modules, are prefabricated by machine in a production hall. These building modules are then used to assemble prefabricated houses. Besides saving time on the construction site, the machine prefabrication of the building modules in the production hall also offers qualitative advantages. The building modules are preferably wall elements and roof / ceiling elements of a prefabricated house. Prefabricated wall elements and roof / ceiling elements are preferably flat and elongated timber frame elements. At various stations, different process steps are carried out on the timber frame elements. In particular, various panel materials are attached to a wooden substructure using fasteners. Furthermore, cutouts are made in the panel materials, which are required, for example, for windows, doors, or electrical outlets.Today, the process steps are performed either manually by carpenters or by machining centers equipped with clamping units and cutting tools. It is common practice for a machining spindle, which is mounted on the machining center and movable, to be used for machining the workpiece. This spindle is either permanently coupled to a cutting tool or can be used to change between different cutting tools via a moving tool changer. Furthermore, it has been standard practice for the various clamping units to be mounted on the machining center by the operator using separate, movable mounting units. Compared to the cutting tools, the clamping units are significantly larger and heavier.This makes the machining portals heavier overall and less agile when moving along the workpiece. Furthermore, operators of such machining devices must manually replace individual clamping units, for example, for maintenance or replacement, which increases the potential for errors. In particular, it can happen that either the wrong clamping units are installed or removed, or that the clamping units are incorrectly mounted on the machining portal. Moreover, no machining of the workpieces can take place during the sometimes time-consuming manual replacement of the clamping units. Due to the limited space on the machining portal and the lack of technical solutions, many process steps still have to be performed manually by the operator.

[0003] It is therefore an object of the present invention to optimize existing processing methods, particularly for timber frame structures used in prefabricated house construction, with a view to increasing the automation of process steps. This object is achieved according to the invention by a device according to claim 1 and a method according to claim 12.

[0004] The device according to the invention for processing workpieces, such as, in particular, wooden frame elements, comprises a motion unit for a process automation unit that is movable in the longitudinal direction of the device. The device further comprises a storage station with a provisioning unit for providing the process automation unit. The storage station is preferably arranged in a stationary position with respect to the longitudinal direction of the device and a transverse direction of the device perpendicular to the longitudinal direction. The motion unit comprises a receiving unit for the process automation unit and is designed such that, for a changeover operation, the motion unit can assume a predefined position relative to the storage station and preferably automatically pick up the process automation unit from the storage station into the receiving unit or, more preferably, automatically place it from the receiving unit into the storage station.

[0005] The term "storage station" refers to any magazine in which process automation components can be stored. The term "motion unit" refers to any movable structure that can move relative to the storage station. The term "receiving unit" refers to any coupling device with which the process automation component can be coupled to or uncoupled from the motion unit. The term "process automation component" refers to any device that includes an interface for coupling to the receiving unit, a frame, and a device that is preferably removable and mounted within the frame. The device is selected for a specific functionality or process step to be performed on the workpiece. Examples of such functions or process steps include...Fastening, cleaning, measuring, marking but also machining, whereby the respective device for machining includes its own spindle drive.

[0006] The storage station comprises at least one staging unit. The staging units of the storage station temporarily store the process automation components required for machining the workpiece. The staging units of the storage station are located within reach of the receiving unit. The motion unit moves to the storage station and, with the aid of the receiving unit—provided a receiving position is available on the receiving unit—preferably automatically picks up the process automation component required for the next process step from the storage station without requiring manual operator intervention. The motion unit then automatically moves to the workpiece and executes the next necessary process step with the newly connected process automation component.After the relevant process step has been executed, if an uncoupled process automation unit is needed for the next process step, and in particular if there is no free space available at the receiving unit for another process automation unit, the movement unit automatically moves back to the storage station, the process automation unit is placed back into the storage station, and another process automation unit required for the next process step is picked up.

[0007] The advantages of such a device are that the process automation components do not all need to be permanently mounted on the motion unit. Consequently, the weight of the motion unit is reduced and its agility is increased. Process automation components, preferably stored near the floor in the storage station, can be conveniently serviced by operators while the workpiece is simultaneously being processed by the motion unit. The automatic exchange of individual process automation components significantly reduces changeover time. Therefore, keeping the process automation components in the storage station increases both ease of maintenance and efficiency.Furthermore, the storage station offers the possibility that significantly more process steps can be automated using the relevant units, and space is already available for future novel units for new process steps.

[0008] The workpieces consist of preferably refined raw materials assembled into a wooden frame element. Preferably, the workpieces are designed as wood panel elements or solid wood elements. In a preferred embodiment, the workpieces to be processed lie on a workpiece support of the device, the workpiece support fixing the workpieces for processing, and preferably being stationary on the floor in both the longitudinal and transverse directions. It is also possible for the workpieces to be transported on the workpiece support in the longitudinal and / or transverse direction. Furthermore, it is possible for the workpieces to be arranged upright against the workpiece support. Since several storage stations can also be positioned adjacent to the workpiece to be processed, this increases the processing versatility.The flexibility of the movement unit has been further increased. It is also possible for the storage station to be permanently mounted on a ceiling or wall.

[0009] The motion unit is, in particular, a manipulator, which in a preferred embodiment is designed as a movable gantry or as a movable articulated robot. The movable gantry essentially consists of a horizontal guide beam and two vertical supports, the horizontal guide beam being aligned parallel to the transverse direction. It is obvious that the processing device can also comprise several longitudinally movable motion units instead of just one. Multiple motion units are particularly advantageous for the parallel processing of a very large workpiece, especially one extending several meters in length. The receiving unit and the process automation unit are preferably provided with interfaces for mutual coupling.

[0010] According to a preferred embodiment, the device comprises a support structure extending along the longitudinal direction of the device, on which the motion unit for movement along the support structure is movably mounted. The receiving unit is movably mounted on the motion unit in the transverse direction and in a vertical direction perpendicular to both the longitudinal and transverse directions with respect to the bearing station. Particularly preferably, the motion unit is designed to be automatically adjustable in the vertical direction with respect to the bearing station. The support structure enables precise, predefined displacement and positioning of the motion unit in order to process the workpiece as accurately as possible at the predefined positions. The adjustability of the receiving unit along the motion unit in both the transverse and vertical directions also achieves precise positioning of the respective unit for process automation.

[0011] The term "support structure" refers to any support system or structure on which the motion unit can move longitudinally. The longitudinal direction corresponds to the extension direction of the support structure. The support structure is preferably aligned parallel to a side surface of the workpiece. With such a device, the motion unit can move the process automation unit attached to the receiving unit longitudinally, transversely, and vertically. It is advantageous that the receiving unit can reach the storage station's supply units and pick up or place down the process automation units. Furthermore, the process automation unit arranged on the motion unit can access all possible points on a workpiece's horizontal surface as well as its vertical side surfaces for processing.

[0012] In a preferred embodiment, the receiving unit is arranged on a so-called aggregate carrier. An aggregate carrier is understood to be any aggregate slide on which the receiving unit can be arranged and with which the receiving unit can be moved laterally and vertically along the movement unit.

[0013] In alternative embodiments, at least that part of the motion unit on which the receiving unit is arranged is designed to be adjustable along a vertical direction relative to the storage station, either automatically or manually. With automatic adjustability of the motion unit, the motion unit can be preset to different height profiles of the workpiece before processing. This advantageously allows the vertical distance between the process automation unit and the workpiece to be kept small, thereby increasing the processing speed.

[0014] According to a preferred embodiment, the support structure is designed in the form of two longitudinally parallel and aligned travel profiles spaced at a predefined distance. The storage station is arranged according to at least one of the following variants: longitudinally overlapping with the travel profiles and / or overlapping with an imaginary extension of the travel profiles, and / or transversely overlapping with at least one travel profile, or within the travel profiles, or outside the travel profiles. The various arrangement variants allow the processing device to be flexibly designed depending on the size of the storage station and the configuration of the motion unit, for example, as a gantry or articulated robot. For example, if a very large storage station with many (i.e.,If more than 10 storage units are required, the storage station could be designed and arranged such that it overlaps both travel profiles in the transverse direction and is positioned both alongside the travel profiles and along an imaginary extension of the travel profiles in the longitudinal direction. Conversely, if only a small storage station with a few (i.e., a maximum of 5) storage units is required, the storage station could be designed and arranged such that it overlaps only one of the travel profiles in the transverse direction and is positioned along the imaginary extension of the travel profiles in the longitudinal direction.With such a small storage station and two motion units in the form of two articulated robots, each on one of the travel profiles, the articulated robot on the travel profile overlapping the storage station could move to a maximum distance close to the storage station, while the articulated robot on the other travel profile could move longitudinally beyond the position of the storage station. Furthermore, the various arrangement options for the storage station allow for optimal provision of the process automation components and the adaptation of their positioning within the storage station to customer-specific requirements.

[0015] The term "two parallel travel profiles" refers to any rail or guide system on which the motion unit can move and is guided. It is advantageous that the motion unit can not only move along the travel profiles in the longitudinal direction but is also guided, thus enabling precise and repeatable positioning of the motion unit in the longitudinal direction, particularly with respect to the storage station.

[0016] In particular, the two parallel guide profiles are each arranged next to the workpiece and preferably run longitudinally along the longest side of the workpiece. It is advantageous that the orientation of the movable portal in the longitudinal and transverse directions coincides with the orientation of the workpiece. In a further embodiment, it is advantageous to guide an articulated robot arm on one of the parallel guide profiles.

[0017] According to a preferred embodiment, the storage station with the process automation unit has an upper height profile in the transverse direction. Correspondingly, the motion unit with the process automation unit has a lower height profile in the transverse direction, which lies at least partially and preferably completely above the height profile of the storage station.

[0018] The upper height profile of the storage station is a transverse profile line that reflects the upper extent of the storage station in the vertical direction. Similarly, the lower height profile of the motion unit is a transverse profile line that runs along a lower edge of the motion unit and reflects its lower extent in the vertical direction. This arrangement and configuration of the motion unit and the storage station allows the motion unit to move longitudinally across the storage station. Such an arrangement is particularly advantageous when two workpieces arranged side-by-side in the longitudinal direction are to be processed by a single motion unit.In this case, the storage station is arranged between the two workpieces, whereby the motion unit with at least one process automation unit can reach both workpieces for processing and, if necessary, can exchange the at least one process automation unit at the storage station for at least one other process automation unit.

[0019] According to a further preferred embodiment, the device also comprises a workpiece support, wherein a processing chamber for a workpiece to be processed, arranged on the workpiece support, is provided above the workpiece support. The processing chamber has an upper height profile in the transverse direction. The storage station with at least one unit for process automation similarly has a lower height profile in the transverse direction, which, according to the preferred embodiment, is arranged at least partially, or more preferably, over the entire transverse direction of the workpiece support processing chamber above the upper height profile of the processing chamber.

[0020] The lower height profile of the storage station is a third profile line running transversely, which follows a lower edge of the storage station. The upper height profile of the workpiece support processing area is a fourth profile line running transversely, which reflects the upper extent of the processing area in the vertical direction. The processing area is a space that can accommodate, in particular, the largest possible workpiece in the vertical direction.

[0021] With this arrangement and design of the workpiece support, including the previously defined workpiece dimensions and the storage station, it is possible for either the workpiece alone or the workpiece support with the workpiece to be transported under the storage station. Such an arrangement is particularly advantageous in longer production lines, where a workpiece is transported from one workpiece processing device to the next. In such a production line, several motion units and several storage stations can be arranged longitudinally one after the other, with the individual motion units having only a limited travel range and being able to reach only one storage station or only a limited number of the installed storage stations.Especially in fast-paced production lines with large production volumes, such an arrangement and design of the device consisting of at least one workpiece support and at least one storage station is useful.

[0022] According to a preferred embodiment, the storage station comprises at least one staging unit and at least one further staging unit. The at least one staging unit and the at least one further staging unit are spaced apart from each other in the transverse direction.

[0023] The term "storage unit" refers to any storage location in which at least one process automation component can be stored. The storage units are preferably arranged side-by-side in a line running transversely and spaced apart from one another, and are within reach of the receiving unit. In a larger storage station, the storage units are preferably arranged in two or more parallel lines running transversely. The movement unit, together with the receiving unit, which is movable both transversely and vertically, can pick up and / or place process automation components from the storage units.

[0024] Such an arrangement of the supply units is particularly advantageous when changing several process automation units during a single changeover operation, as no additional longitudinal movement of the motion unit is necessary to pick up and / or put down the process automation units. A further advantage is that the storage station with the supply units can thus be arranged in a space-saving manner between two workpiece supports.

[0025] In a further preferred embodiment, the at least one staging unit and at least one further staging unit are designed to be adjustable in height, either jointly or individually, to facilitate the loading and unloading of the process automation assemblies by the receiving unit. With a transverse length of, for example, 6000 mm, up to six staging units for process automation assemblies with different process functionalities can preferably be arranged side by side in the transverse direction to enable a wide range of processing operations on the workpiece.

[0026] According to a preferred embodiment, the process automation unit has a storage device, preferably designed as a suspension device, for storing or, more preferably, suspending the unit in the storage station. The supply unit accordingly has at least one receiving device for the storage device. The term "storage device" refers to any technical device by which the process automation unit can be stored or temporarily placed on the supply unit. The term "receiving device" refers to any technical device for receiving a process automation unit.

[0027] In a first embodiment, the storage device and the receiving device are characteristically designed for each specific type of process automation unit, such that each storage location in the storage station is predefined for a specific type of process automation unit, and the movement unit must pick up and place the respective type of process automation unit at the same storage location. Thus, the operator of the device, who wishes to service a certain process automation unit, knows in advance where to find the relevant process automation unit in the storage station.Furthermore, in this case, the respective storage and receiving equipment can be adapted to the weight and size of the respective process automation unit in order to save costs and materials, because not all storage and receiving equipment needs to be designed for the largest or heaviest process automation unit.

[0028] In a second embodiment, the at least one receiving device and storage devices for different types of process automation units are designed uniformly. Thus, the storage devices for the process automation units and the receiving units of the storage station are standardized, allowing the device to place a process automation unit at any available storage location that can be reached as quickly as possible, thereby reducing the processing time of the workpieces with the device.

[0029] Furthermore, in a particular embodiment, a storage unit has two receiving devices for two process automation units, thus saving material during the manufacture of the storage station and thereby reducing manufacturing costs. The space required in the storage station for storing two process automation units is also reduced.

[0030] The receiving device is particularly preferably designed as a three-point receiver that can hold the unit for process automation in a positionally accurate manner.

[0031] According to a preferred embodiment, the process automation unit comprises a first unit for processing the workpiece, for example, a first unit for machining the workpiece, and a second unit for processing the workpiece, for example, a unit for measuring, marking, or cleaning the workpiece. This saves storage space at the storage station because it eliminates the need for a separate storage space for a first process automation unit with the first unit and a second, separate storage space for a second process automation unit with the second unit. Furthermore, the AND configuration saves time that would otherwise be required to change the process automation units at the storage station, thus accelerating the entire machining process with the device.

[0032] The first processing unit and the second processing unit are selected from the following group: fastening unit, adhesive unit, milling unit, sawing unit, drilling unit, cleaning unit, marking unit, sensor or measuring unit.

[0033] A sensor or measuring unit is understood to be any technical device that comes into contact with the workpiece, either physically or non-physically (e.g., via laser), and performs a measurement or inspection of the workpiece, e.g., whether a nail has been driven in only partially or completely, or whether a nail has been driven in at the predefined location.

[0034] Preferably, the first processing unit and / or the second processing unit are mounted on a mounting bracket of the process automation unit in a height-adjustable and / or interchangeable manner. The height-adjustable and / or interchangeable mounting on the mounting bracket is particularly suitable for accommodating different units with varying vertical dimensions within the mounting bracket.

[0035] According to a preferred embodiment, the process automation unit is rotatably mounted on the receiving unit. In particular, the process automation unit is rotatably mounted about a vertical axis such that a predefined spatial region, in which the workpiece is to be processed by the current position and orientation of the process automation unit, remains unchanged. A predefined spatial region in which the workpiece is to be processed is understood to be a region in which, for example, the tool comes into contact with the workpiece, or in which the fastening element of the mounting unit contacts the workpiece, or in which measurement signals from a sensor unit reach the workpiece.

[0036] With such a receiving unit, the process automation unit, preferably a stapling device, is rotated about a vertical axis parallel to the vertical direction. Staples of the stapling device can thus be driven into the workpiece at different angles between a staple bridge and, for example, the longitudinal direction. The staple bridge is the wire bridge between the two wire ends of the respective staple that are driven into the workpiece.

[0037] Rotation around the vertical axis is particularly advantageous when, in particular, the wire ends of a staple in the stapler need to be driven into the different grain directions of a workpiece, preferably wooden, thus improving the holding power of the fastener. It is also advantageous that a predefined area, corresponding to the position of the stapler's exit nozzle, remains unchanged by the rotation around the vertical axis, eliminating the need for readjustment of the stapler's position by the control unit. For this purpose, the vertical axis of rotation is arranged such that an imaginary extension of the axis overlaps the predefined area.

[0038] Preferably, the assembly for process automation is rotatably mounted about a horizontal axis. Such a design of the holding unit is particularly advantageous for enabling nailing tools to be rotated about a horizontal axis parallel to the transverse direction, so that the nailing tool's fasteners can be driven into the workpiece at different angles. Rotation about the horizontal axis is especially advantageous when plate-shaped components are to be fastened to wooden beams of a wooden substructure, where, in particular, vertical driving of fasteners near the joints of the plate-shaped components is disadvantageous. Vertical driving is especially disadvantageous when the wooden beams of the wooden substructure are narrow, for example, with a width of 38 mm.The panel joints run centrally along the wooden beam, leaving only minimal space next to the joints for vertically driving in a fastener. Therefore, nails are driven in at an angle using a hammer tilted around the horizontal axis for process automation. This ensures that the nail securely connects the panel-shaped component to the wooden beam and is driven completely into the beam. This prevents the nail from missing the wooden beam.

[0039] According to a preferred embodiment, the dispensing unit and / or the receiving unit are adjustable in the vertical direction and / or in the transverse direction and / or in the longitudinal direction and / or around the vertical direction and / or in the transverse direction and / or around the longitudinal direction by means of a manual, semi-automatic, or fully automatic adjustment mechanism. With such an adjustment mechanism, the dispensing unit and / or the receiving unit can also be flexibly aligned spatially relative to each other. Advantageously, the dispensing unit and the receiving unit can be coordinated and aligned with each other by the adjustment mechanism, so that the process automation components can be coupled to the receiving unit without interference.

[0040] In a further preferred embodiment, the device for moving and positioning the motion unit relative to the storage station comprises an omega drive. Such a drive allows, in particular, high positioning and repeatability accuracy, so that the process automation assemblies can be picked up from and placed back into the storage station without problems, even during extended operation of the device.

[0041] The invention further relates to a method for picking up or placing a process automation unit from or into a storage station (40), particularly in the case of a workpiece processing device as described in the preceding sections. The method comprises the following steps: - Performing an initial relative movement in the longitudinal direction between a motion unit and the storage station to reach a predefined transfer position, and / or - Performing a second relative movement in the transverse direction between the movement unit and the storage station to reach the predefined transfer position, and / or - Performing a third relative movement in a vertical direction between the movement unit and the storage station to reach the predefined transfer position, and - Picking up or placing the process automation unit at the motion unit or in the storage station at the transfer position.

[0042] According to a further preferred embodiment of the method, the method comprises the following additional steps: - Performing an initial relative movement in the longitudinal direction between the motion unit and the workpiece to achieve a machining position, and / or - Performing a second relative movement in the transverse direction between the holding unit and the workpiece to reach the machining position, and / or - Performing a third relative movement in the vertical direction between the holding unit and the workpiece to reach the machining position, and - Processing the workpiece at the processing position by the unit for process automation

[0043] According to a further preferred embodiment of the method, the first relative movement in the longitudinal direction between the motion unit and the storage station and the second relative movement in the transverse direction between the receiving unit and the storage station are performed simultaneously. Alternatively, the first relative movement in the longitudinal direction between the motion unit and the storage station, the second relative movement in the transverse direction between the receiving unit and the storage station, and the third relative movement in the vertical direction between the receiving unit and the storage station are performed simultaneously. Performing the relative movements simultaneously for a changeover operation at the storage station results in increased efficiency in workpiece processing due to time savings. Alternatively, the relative movements can also be performed sequentially.

[0044] According to a further preferred embodiment of the method, the first relative movement in the longitudinal direction between the motion unit and the bearing station is performed such that the motion unit can move over the bearing station. This allows the bearing station to be positioned at any position along the travel path of the motion unit, and the motion unit's movement is not restricted.

[0045] In a first particularly preferred embodiment, a workpiece support with a workpiece arranged on the workpiece support and, in particular, finished by the machining device, passes under the storage station. In a second particularly preferred embodiment, the workpiece is transported under the storage station by a transport system arranged on the workpiece support, wherein the workpiece support itself is stationary with respect to the storage station.

[0046] Such a process step allows the storage station to be placed on the travel path of the workpiece support or on the transport path of the workpiece without the storage station being an obstacle to movement of the workpiece support and / or the workpiece.

[0047] According to a further preferred embodiment of the method, several process automation units are picked up or placed down from the storage station simultaneously or sequentially during a changeover operation. This simultaneous or sequential picking up or placing of the process automation units during a changeover operation results in increased efficiency due to time savings, because several processing steps can be performed on the workpiece after the changeover operation before another changeover operation needs to be initiated for further processing steps.

[0048] Further features and advantages of the invention will become apparent from the following detailed description of exemplary embodiments of the invention, with reference to the figures in the drawing, which show essential details of the invention, and from the claims. The features shown therein are not necessarily to scale and are depicted in such a way that the inventive features can be clearly seen. The individual described features can be implemented individually or in any combination in various exemplary embodiments of the invention.

[0049] Preferred embodiments of the invention are shown in the figures of the drawing and are explained in more detail in the following description, wherein identical reference numerals refer to identical or similar or functionally identical device components or process steps.

[0051] Fig. Figure 1 shows one of two preferred embodiments of a device 10 for processing workpieces 80. The device 10 comprises the following main components: a motion unit 20 in the form of a machining portal, a storage station 40, a support structure 65 for the motion unit 20, preferably a workpiece support 70 for the workpieces 80, and a control unit 90 for controlling the motion unit 20, the storage station 40, and the workpiece support 70. In a second preferred embodiment (not shown) of a further device for processing workpieces, an articulated robot, or two articulated robots, are used as the motion unit instead of the machining portal, each on a rail of the support structure 65.

[0052] The in Fig. The motion unit 20 shown in Figure 1 is arranged to be movable in the x-direction (corresponding to the longitudinal direction) on parallel guide profiles 66 of the supporting structure 65. The motion unit 20 is preferably constructed as a portal-shaped base structure 15, wherein the portal-shaped base structure 15 essentially comprises a guide beam 35 extending in the y-direction (corresponding to the transverse direction) and two supports 36 extending in the z-direction (corresponding to the vertical direction), at the lower end of which motion means 103 are located (see also Figure 1). Fig. 9a / 9b) such as, for example, a wheel or preferably a roller for rolling on the support structure 65. The portal-shaped base structure 15 extends in the vertical direction preferably in the range of 1700 mm - 2000 mm, in the longitudinal direction preferably in the range of 1700 mm - 2000 mm, and in the transverse direction preferably in the range of 4500 mm - 6200 mm. The longitudinal feed of the motion unit 20 is effected by a drive unit 37, which is arranged in relation to the Fig. 9 is described in more detail. One or preferably two aggregate carriers 21 are movably mounted on the guide beam 35 in the transverse direction, wherein at least one receiving unit 30 for receiving an aggregate 50 for process automation is arranged on one of the aggregate carriers 21. The receiving unit 30 is a coupling device for coupling the aggregate 50. The receiving unit 30 for receiving the aggregate 50 is movably mounted on the aggregate carrier 21 in the vertical direction. A guide system is arranged on the cuboid guide beam 35, wherein one of the aggregate carriers 21 is movably mounted in the transverse direction via at least one guide rail and, more preferably, via two parallel guide rails of the guide system arranged one above the other.The two guide rails of the guide system are preferably arranged on a long, vertically oriented surface of the cuboid guide beam 35 and thus lie in the same cylindrical plane. Preferably, the two guide rails of the guide system are spaced 200 mm to 300 mm apart. The portal-shaped base structure 15 is designed such that the motion unit 20 can be moved over the workpiece support 70 with a workpiece 80 located thereon, and such that the upwardly directed horizontal surface of the workpiece 80 can be processed, and preferably also the vertical side surfaces of the workpiece 80 can be processed by the motion unit 20. Processing refers, for example, to a fastening process, a machining process such as a cutting process, a cleaning process, a marking process, or a measuring or inspection process.

Preferably, the first slide 23 extends vertically in the range of 1300 mm to 1500 mm and laterally in the range of 200 mm to 300 mm. For vertical displacement of the receiving unit 30, it is preferably slidably mounted on the first slide 23 via a vertical guide rail 28. In particular, the receiving unit 30 can be moved and fastened at different mounting positions on the vertical guide rail 28 using fasteners. The mounting positions extend in the range of 400 mm to 600 mm on the vertical guide rail 28. The movement of the receiving unit 30 can be performed manually or, preferably, by motor.The first slide 23 of the aggregate carrier 21 is slidably arranged on the second slide 29 of the aggregate carrier 21 via a guide system. In particular, a vertically oriented guide rail is preferably arranged on the first slide 23, and preferably two parallel and vertically oriented guide rails are arranged on the first slide 23. Preferably, the two guide rails are located on a side surface of the first slide 23 that is parallel to the vertical direction and lie side by side in the same zy-plane. A guide element, or preferably several guide elements, are arranged on a side surface of the second slide 29 that faces the first slide 23. The guide elements are part of the guide system between the first and second guide slides for moving the first slide 23 vertically. Preferably, the guide elements lie side by side in the same zy-plane.In particular, the second slide 29 extends in the vertical direction in the range of 800 mm - 1000 mm and in the transverse direction in the range of 200 mm - 300 mm.

[0079] One in Fig. The first drive unit 24, shown in Figure 5, consists of a fixed drive part and a movable drive part. The fixed drive part is detachably attached to the second slide 29, and the movable drive part is detachably attached to the first slide 23, so that the first slide 23 can be moved vertically by the first drive unit 24. The maximum displacement of the first slide 23 by the first drive unit 24 is preferably in the range of 600 mm and more preferably in the range of 700 mm. The first drive unit 24 is preferably a pneumatically operated drive unit 24 and more preferably a pneumatic cylinder.The first drive unit 24, comprising a fixed drive part (a cylinder housing) and a movable drive part (a piston with a rod), generates linear motion. The piston and rod are movably mounted within the cylinder housing to convert pneumatic energy into linear mechanical kinetic energy. The piston and rod have a fastening device at its end, allowing the rod to be connected to the first slide 23. The cylinder housing also has a fastening device, enabling it to be connected to the second slide 29. It is understood that a hydraulically operated or an electrically operated drive unit 24 can also be used to move the first slide 23.The first drive unit 24 serves the purpose of moving the unit 50, coupled to the receiving unit 30, in the vertical direction to an upper end position and a lower end position. The lower end position preferably corresponds to the workpiece surface to be machined. To reach the lower end position, the unit 50 is moved by the first drive unit 24 in the direction of the workpiece 80, so that the support wheels 56 of the unit 50 contact the workpiece 80. Consequently, the support wheels 56 hold the workpiece 80 down, ensuring low-friction movement of the unit 50 over the workpiece 80. By connecting the first drive unit 24 to the control unit 90, the pressure with which the support wheels 56 of the unit 50 hold the workpiece 80 down can preferably be automatically regulated.Preferably, an additional device can mechanically clamp the movable part of the pneumatically operated drive unit 24 after the support wheels 56 have been placed on the workpiece 80, so that the assembly 50 can be fixed at a specific height after the support wheels 56 have been placed on the workpiece 80. In a particular embodiment, the first slide 23 with the assembly 50 can be mechanically decoupled from the movable drive part of the pneumatically operated drive unit 24 by a further additional device in order to mount it floatingly in a range of preferably 40 mm, so that the assembly 50 can also be moved over uneven workpieces 80, i.e., those that are not flat on their upper surface.

[0080] In a preferred embodiment, an additional lifting unit 25 is integrated between the movable drive part of the first drive unit 24 and the first slide 23, allowing the first slide 23 to be raised further in the vertical direction. Preferably, the additional lifting unit 25 is pneumatically operated. An advantage of the additional lifting unit 25 is that the unit 50 can be briefly raised from the workpiece 80 and lowered back onto the workpiece 80 during machining. Preferably, the unit 50 can be raised by the additional lifting unit 25 in the range of 100 mm to, more preferably, 200 mm. Thus, obstacles on the surface, in particular openings in the surface of the workpiece 80, can be overcome by briefly raising and lowering the unit.Brief lifting and lowering with the additional lifting unit 25 is advantageous in order to quickly overcome obstacles and thus ensure a rapid continuation of processing.

[0081] One in Fig. The second drive unit 26 of the aggregate carrier 21, as shown in Figure 5, is arranged on the second slide 29, preferably being adjustably mounted on a side surface of the second slide 29. The second drive unit 26 is preferably arranged above the guide unit 22. With the second drive unit 26, the aggregate carrier 21 can execute a linear movement in the transverse direction along the guide beam 35 of the motion unit 20. The second drive unit 26 is preferably an electric motor or, more preferably, an electric servo motor. The use of the electric servo motor enables precise positioning and motion control during operation. It is understood that the second drive unit 26 can also be designed as a pneumatic or hydraulic motor, and motors with gearboxes can also be used.Preferably, a gear 27 lying in the xy-plane is arranged on the second drive unit 26, so that the gear 27 can engage with a rack extending transversely and arranged on the portal-shaped base structure 15, and the aggregate carrier 21 can be moved. To optimally engage the gear 27 with the rack, the second drive unit 26 is preferably arranged on an adjustment device. The adjustment device allows the second drive unit 26 to be adjusted vertically and longitudinally. More preferably, the adjustment device includes a spring mechanism. Preferably, the spring mechanism allows a spring movement of the second drive unit 26 in the longitudinal direction, and more preferably, the spring mechanism also allows a spring movement in the transverse direction.Thus, any potential straightness error of the rack and / or any potential misalignment of the gear 27 can be compensated for by the spring device in order to minimize wear on the contact surfaces of the gear 27 and the rack during operation. The second drive unit 26 is furthermore supplied with energy by the motion unit 20, preferably via electrical lines. The second drive unit 26 is also connected to the control unit 90 via control lines 91 to communicate with the control unit 90.

[0082] Both the control lines 91 on the aggregate carrier 21 and the electrical, pneumatic and hydraulic lines for supplying power to all electrical, pneumatic and hydraulic consumers on the aggregate carrier 21 preferably run via one or more energy chains from the motion unit 20 to the aggregate carrier 21. On the aggregate carrier 21 itself, the aforementioned lines also run via one or more energy chains from the first slide 23 to the second slide 29.

[0083] In Fig. 6. For clarity, only the motion unit 20 and the bearing station 40 of the device 10 are shown in a schematic diagram. An upper height profile 86 of the bearing station 40 and a lower height profile 85 of the motion unit 20 are also shown. This configuration of the bearing station corresponds to the first height profile of the bearing station, which was already described in a previous section. It can be seen that the motion unit 20 and the bearing station 40 are designed and arranged such that the upper height profile 86 of the bearing station 40 runs below the lower height profile 85 of the motion unit 20 in the zy-plane.

[0084] The upper height profile 86 of the storage station 40 is a first profile line that reflects the maximum extent of the storage station 40 in the vertical direction. In particular, the first profile line runs in the transverse direction along the upper edge of the crossbeam 46 of the storage station 40 and further encloses a profile of all components projecting above the upper edge of the crossbeam 46, wherein in particular the supply units 42 and the aggregates 50 project above the upper edge of the crossbeam 46 of the storage station 40.

[0085] The lower height profile 85 of the motion unit 20 is a second profile line extending in the transverse direction, wherein the second profile line runs along the lower edge of the guide beam 35 and reflects the lower extent of the guide beam 35 and the receiving unit 30 with a coupled assembly 50 in the height direction. Although the receiving unit 30 with a coupled assembly 50 is in an upper end position, the assembly 50 can project below the lower edge of the guide beam 35 of the motion unit 20. In particular, the second profile line is defined by a profile in the zy-plane of all components projecting below the lower edge of the guide beam 35 in the region of the transverse extent of the bearing station 40.

[0086] Consequently, in Fig. 6. An arrangement can be identified in which the upper height profile 86 of the storage station 40 lies below the lower height profile 85 of the motion unit 20, so that the motion unit 20 can move over the storage station 40 in an operating state. Such an arrangement is particularly advantageous if two workpieces 80 arranged side by side in the longitudinal direction are to be processed by one motion unit 20. In this case, the storage station 40 is arranged between the two workpieces 80, whereby the motion unit 20 with its aggregates 50 can reach both workpieces 80 for processing and can exchange the aggregates 50 at the storage station 40 if necessary.

[0087] In Fig. Figure 7 shows, for clarity, only the motion unit 20, the storage station 40, and the workpiece support 70 of the device 10 in a schematic representation. A lower height profile 87 of the storage station 40 and a processing chamber 88 are also shown. This configuration of the storage station corresponds to the second height profile of the storage station, which was already described in a previous section. It can be seen that the storage station 40 is designed and arranged such that the lower height profile 87 of the storage station 40 runs above the processing chamber 88 in the zy-plane. The lower height profile 87 of the storage station 40 is a third profile line extending in the transverse direction, with the third profile line running along the lower edge of the crossbeam 46 and reflecting the lower extent of the crossbeam 46 in the vertical direction.

[0088] The processing space 88 is a space for a workpiece 80 arranged on the workpiece support 70, wherein the processing space 88 is preferably located above the workpiece support 70 and reflects the largest possible workpiece 80, particularly in its vertical dimension. The base area of ​​the processing space 88 corresponds to the dimensions in the longitudinal and transverse directions of the support surface 72 of the workpiece support 70. The vertical dimension of the processing space 88 corresponds to the predefined maximum height that a workpiece 80 may have.

[0089] Consequently, in Fig. Figure 7 shows an arrangement in which the lower height profile 87 of the storage station 40 lies above the processing area 88, such that the workpiece 80 can be transported under the portal-shaped base structure 41 of the storage station 40 in an operating state. Such an arrangement is particularly advantageous in longer production lines, where a workpiece 80 is transported from one workpiece processing device to the next. In such a production line, several motion units 20 and several storage stations 40 can be arranged longitudinally one behind the other, with the individual motion units 20 having only a limited travel range and preferably being able to reach only one storage station 40 or a limited number of the available storage stations 40. Such an arrangement is particularly useful in fast-paced production lines with large production volumes.

[0090] As the Fig. As shown in Figures 8a to 8c, the storage station 40 can be arranged in different positions within the installation area provided for the device 10. In particular, nine arrangement variants of the storage station 40 are advantageous, so that the position of the storage station 40 can be adapted to different customer-specific requirements.

[0091] A first arrangement variant 97a, in which the storage station 40 is arranged longitudinally alongside the travel profiles 66 and transversely within the travel profiles 66, is particularly well suited for positioning the storage station 40 within the working area of ​​the portal or the articulated robot in a particularly easily accessible manner. The portal with the picking unit 30 can be moved over the storage station 40 to pick up the respective unit 50. The location specification "alongside the travel profiles 66" means that the storage station 40 is located longitudinally at a position where the travel profiles 66 run.

[0092] A second arrangement variant 97b, in which the storage station 40 is located next to an imaginary extension of the travel profiles 66 and transversely within the travel profiles 66, is particularly well suited to keeping the working area of ​​the portal or the articulated robot clear for particularly large workpieces 80. This is especially true when there is little space for a storage station 40 transversely outside the travel profiles 66. An articulated robot could easily reach the storage station 40 positioned in this way due to the large range of motion of its robot arm. The portal's receiving unit 30 would have to be designed to reach the storage station 40 and the assemblies 50 stored therein. In particular, the receiving unit 30 would have to be designed so that it can move longitudinally and reach an assembly 50 by means of a corresponding longitudinal movement function.In addition to the imaginary extension of the driving profiles 66, this means that the storage station 40 is located in the longitudinal direction at a position where no driving profiles 66 run.

[0093] A third arrangement variant 97c, in which the storage station 40 is arranged longitudinally alongside the travel profiles 66 and transversely outside the travel profiles 66, is particularly suitable for keeping the working area of ​​a gantry or an articulated robot clear for particularly large workpieces 80. This is especially true when there is little space for a storage station 40 in the longitudinal direction along an imaginary extension of the travel profiles 66. An articulated robot could easily reach the storage station 40 positioned in this way due to the large range of motion of its robot arm. The portal's receiving unit 30 and / or the portal itself would have to be designed to reach the storage station 40 and the assemblies 50 stored therein. In particular, the guide beam 35 of the portal would have to be designed with a transverse extension to ensure accessibility by the receiving unit 30.

[0094] The further arrangement variants are characterized in that the storage station 40 is arranged longitudinally both next to the driving profiles 66 and next to an imaginary extension of the driving profiles 66 and in the transverse direction within the driving profiles 66, that the storage station 40 is arranged longitudinally either next to the driving profiles 66 or next to an imaginary extension of the driving profiles 66 or both next to the driving profiles 66 and next to an imaginary extension of the driving profiles 66 and in the transverse direction overlaps at least one of the driving profiles, or that the storage station 40 is arranged longitudinally next to the driving profiles 66 or both next to the driving profiles 66 and next to an imaginary extension of the driving profiles 66 and in the transverse direction outside the driving profiles 66.

[0095] In the Fig. 9a and Fig. 9b is already related to Fig. Figure 1 shows in detail the drive unit 37 for longitudinally advancing the motion unit 20. The drive unit 37 is preferably designed as a so-called omega drive and essentially consists of two drive rollers 100, two motors 101, two power transmission elements 102, four motion elements 103, and four deflection rollers 104, wherein the drive rollers 100, the motors 101, the power transmission elements 102, and the motion elements 103 are preferably identical. In the embodiment shown, the two drive rollers 100 and the two motors 101 of the drive unit 37 are arranged in the guide beam 35 of the motion unit 20, wherein the drive rollers 100 are preferably rotatably mounted in the guide beam 35 about an axis parallel to the transverse direction and are mechanically connected to the respective motor 101.The drive rollers 100 are preferably cylindrical and have a toothed structure on their cylindrical surface. The two motors 101 are preferably detachably attached to the guide beam 35 and transmit rotational energy to the drive rollers 100 via preferably separate drive shafts. The motors 101 are preferably electric motors with a gearbox, and further preferably electric servomotors connected to the control unit 90 via control lines 91. In contrast to other motor types, the electric servomotor offers the advantages that the motion unit 20 can be positioned very precisely and accurately in an operating state and can react quickly to control signals from the control unit 90.

[0096] The motion elements 103 of the drive unit 37 are arranged in the respective supports 36 of the motion unit 20, wherein the motion elements 103 are preferably rotatably mounted in the respective supports 36 about an axis parallel to the transverse direction, so that the motion elements 103 can bear the load of the motion unit 20 and the motion unit 20 is movably mounted on the travel profiles 66. Each motion element 103 has a running surface, wherein the motion element 103 preferably has two convex running surfaces, so that the contact with the travel profile 66 is reduced to a minimum and consequently the friction between the travel profile 66 and the motion element 103 is minimized.The deflection rollers 104 are also arranged in the respective supports 36, wherein the deflection rollers 104 are preferably rotatably mounted in the respective supports 36 about an axis parallel to the transverse direction, so that the respective power transmission means 102 can be deflected from the drive roller 100 to the travel profile 66. As in . Fig. As shown in Figure 9a, a power transmission means 102, in particular a flat belt with a toothed structure on its surface, is preferably adjustable and attached to both ends of the respective drive profile 66 via attachment points. The power transmission means 102 can be tensioned, in particular via the attachment points, so that a tensile force can be generated and thus a connection is created between the drive unit 37 and the drive profile 66.The flat belt with a toothed structure on its surface runs horizontally from the ends of the respective driving profile 66 along the driving profile 66 to the deflection rollers 104 and is then deflected vertically by the deflection rollers 104 to the drive roller 100, so that the toothed structure of the flat belt can engage with the toothed structure of the drive roller 100 in order to convert the rotational kinetic energy of the motor 101 into linear kinetic energy and thus set the motion unit 20 into linear longitudinal motion.To set the motion unit 20 into a uniform and symmetrical linear longitudinal movement, thereby guaranteeing, on the one hand, precise machining of the workpieces 80 by the machining device 10 and, on the other hand, positioning the motion unit 20 as precisely as possible in a transfer position in which assemblies 50 can be picked up from or placed into the storage station 40, the two power transmission means 102 are preferably tensioned with the same tensile force via the attachment points of the two travel profiles 66, and the motors 101 of the drive unit 37 are preferably controlled identically by the control unit 90. In a preferred embodiment, the drive unit 37 has only one motor 101, wherein the one motor 101 is controlled by the control unit 90 and the rotational kinetic energy of the motor 101 is transmitted via a drive shaft to the two drive rollers 100.

[0097] Fig. Figure 10 shows a schematic representation of a method for picking up or putting down an assembly for process automation, such as the assembly 50, from or into a storage station, such as the storage station 40 of the device 10, which is described in various versions in the preceding paragraphs. Such a changeover process is characterized in that a motion unit, such as the motion unit 20, moves towards the storage station, puts down or picks up at least one assembly after reaching the storage station, and then moves back to a processing position for further processing of the already processed workpiece 80 or a newly processed workpiece 80. A further movement of the motion unit to the storage station is already part of another changeover process.

[0098] In this process, the process automation components are picked up from the receiving unit and placed in storage units, such as storage units 42, during a first changeover operation. During a second or subsequent changeover operation, they are placed back into the storage units. In the process example described below, two receiving units are arranged on the motion unit, with one component coupled to each receiving unit. Furthermore, two components are stored in the storage station, which are to be picked up for machining workpiece 80.

[0099] In a first process step 160, the motion unit moves longitudinally towards the storage station and reaches a first target transfer coordinate specified by the control unit. In a second process step 170, the first receiving unit moves transversely towards the storage station and reaches a second target transfer coordinate specified by a control unit, such as control unit 90. In a third process step 180, the first receiving unit moves vertically towards the storage station from an upper end position to a third target transfer coordinate specified by the control unit. The first receiving unit has thus reached a target transfer position.The target transfer position represents the position in which the respective receiving unit is located so close to the storage station that a process automation component can be picked up, for example, by a coupling operation without further movement of the receiving unit, or a decoupling operation can be performed without further movement of the receiving unit. Depending on the pre-positioning of the receiving unit due to a previously completed processing process, either only one or two of steps 160 to 180 might be sufficient to reach the target transfer position.

[0100] In a further process step 190, the first receiving unit decouples the coupled process automation unit and thus sets the process automation unit down. Step 190 can contain two sub-steps: first, the supply and signal lines between the receiving unit and the process automation unit are interrupted, and then the force-fit and / or positive-locking connection between the receiving unit and the process automation unit is released. Alternatively, the two sub-steps could also be performed in one step.

[0101] Subsequently, in a further, optional step 200, the distance between the storage station and the first receiving unit is increased by a relative movement in the vertical direction. This can be achieved, for example, by moving the first receiving unit back to an upper end position in the vertical direction. Step 200 is performed in cases where direct movement in the transverse and / or longitudinal direction to another supply unit is not possible without collision with the storage station due to its design. However, step 200 can be omitted if the storage station is designed accordingly. In a further process step 210, the control unit checks whether all necessary components for process automation have been picked up or placed in the subsequent processing steps.In this example, the control unit decides that an aggregate for process automation should be picked up by the first receiving unit, and thus the procedure or the ongoing changeover process is continued with process step 170.

[0102] In a further process step 170, the first receiving unit moves laterally relative to the storage station and reaches a second target transfer coordinate specified by the control unit. In a further process step 180, the first receiving unit moves vertically towards the storage station from an upper end position to a third target transfer coordinate specified by the control unit. In a further process step 190, the first receiving unit couples the process automation unit located in the storage station, as specified by the control unit, and thus receives the process automation unit.Step 190 can also contain two sub-steps here: first, a force-fit and / or form-fit connection is established between the receiving unit and the process automation unit; and then, the supply and signal lines from the receiving unit and the process automation unit are connected. Alternatively, these two sub-steps could be performed in a single step. Subsequently, in a further, possibly optional, step 200, the distance between the storage station and the first receiving unit is increased by a relative movement in the vertical direction. This can be achieved, for example, by moving the first receiving unit back to an upper end position in the vertical direction.

[0103] In a further process step 210, the control unit checks again whether all necessary components for process automation have been picked up or placed down for the following processing steps. In this example, the control unit decides that a component for process automation should be placed down by the second picking unit, and thus the process continues again with process step 170. The second picking unit moves laterally relative to the storage station and reaches a second target transfer coordinate specified by the control unit. In a further process step 180, the second picking unit moves vertically towards the storage station from an upper end position to a third target transfer coordinate specified by the control unit.In a further process step 190, analogous to the description above, the second receiving unit decouples the coupled process automation unit and places it down. Subsequently, in a further, optional step 200, the distance between the storage station and the second receiving unit is increased by a relative movement in the vertical direction. This can be achieved, for example, by the second receiving unit moving back to an upper end position in the vertical direction. In a further process step 210, the control unit checks whether all necessary process automation units have been picked up or placed down for the following processing steps. In this example, the control unit decides that a process automation unit should be picked up by the second receiving unit, and thus the process continues again with process step 170.

[0104] In a further process step 170, the second receiving unit moves laterally relative to the storage station and reaches a second target transfer coordinate specified by the control unit. In a further process step 180, the second receiving unit moves vertically towards the storage station from an upper end position to a third target transfer coordinate specified by the control unit. In a further process step 190, the second receiving unit couples and receives the further specified process automation unit located in the storage station, analogous to the description above. Subsequently, in a further, optional step 200, the distance between the storage station and the second receiving unit is increased by a relative movement in the vertical direction.This can be achieved, for example, by having the second pickup unit move back to an upper end position in the vertical direction. In a further process step 210, the control unit checks again whether all necessary components for process automation have been picked up or placed for the following processing steps. In this example, the control unit decides that no further components for process automation should be picked up or placed, and thus the process continues with process step 220.

[0105] In a further process step 220, the workpiece 80 is placed on a workpiece support, such as the workpiece support 70, for processing. Process step 220 can alternatively be skipped if the workpiece 80 is already on the workpiece support, particularly if it is to be processed further after the changeover. In a further process step 230, the motion unit moves longitudinally relative to the workpiece 80 and reaches a first target processing coordinate specified by the control unit. In a further process step 240, the first receiving unit moves transversely relative to the workpiece 80 and reaches a second target processing coordinate specified by the control unit.In a further process step 250, the first receiving unit moves vertically relative to the workpiece 80 from an upper end position to a third target processing coordinate specified by the control unit. Through process steps 230 to 250, the first receiving unit reaches a target processing position. The target processing position represents the position in which the respective receiving unit is adjacent to the workpiece and a process can be carried out with respect to the workpiece 80.

[0106] In process step 260, a sensor, for example sensor 60, is used to check whether workpiece 80 is located in the predefined space 53 as intended. If the check reveals that workpiece 80 is not located in space 53, the process either continues with process step 230 or it terminates, and an operator would have to investigate the cause of the error. If, however, the check reveals that workpiece 80 is located in space 53 as expected, in a further process step 270, workpiece 80 is processed by the first process automation unit according to the specifications of the machining program. In a further process step 280, the control unit checks whether all possible machining steps have been carried out by the process automation units located on a unit carrier, such as unit carrier 21.If this is not the case, the control unit decides that the procedure will continue with all or some of the procedure steps 230 to 270 at the same target processing position or another target processing position.

[0107] In a further process step 280, the control unit checks again whether all possible processing steps have been carried out with the process automation units located on the aggregate carrier. If so, the control unit decides that no further processing steps are necessary on workpiece 80 and thus ends the process, or continues the process with step 160 if a further changeover operation for process automation units is required.

[0108] To reach the target transfer position and the target processing position even faster, process steps 160 and 170 as well as process steps 230 and 240 can be executed simultaneously. Even more preferably, process steps 160, 170 and 180 as well as process steps 230, 240 and 250 can be executed simultaneously.

[0109] Furthermore, several receiving units can simultaneously execute process steps 170 and 180, and 190 and 200, in order to simultaneously pick up or place two or more process automation assemblies from the storage station.
