Description

Technical field

[0001] The application relates to a carrier for processing tools suitable for processing a strip material. Furthermore, the application relates to a device for processing a strip material comprising at least one carrier for processing tools. State of the art

[0002] In the prior art, carriers for machining tools, in particular carriers which are displaceable along a linear guide transversely to the direction of expansion of a strip material, are known.

[0003] US Patent 4,604,934 (PPG Industries) discloses a system for positioning multiple carriages along a bridge spanning a work surface. The outermost carriage is connected to a drive unit, and the other carriages can be selectively coupled to adjacent carriages. Each carriage (except the outermost one) can be clamped to a rod. To position the carriages, they are first pushed together in a starting position, then advanced in their coupled configuration by means of the drive unit; successively, the rearmost carriage is then detached from the train at the corresponding position and clamped to the rod. The carriages have a rectangular base.

[0004] EP 0 997 444 (HEGLA) describes a method and a device for positioning several machining heads of a multi-head machining center, which are movable along at least two spatial axes. This enables fully automatic positioning of the machining heads along a bridge spanning a cutting table. The machining heads are assigned to individual carriages and are initially arranged as close together as possible for positioning. The carriages are then moved by one of the carriages, which can be driven along the longitudinal axis of the bridge. After reaching the respective target position, the carriage in question is locked with respect to the longitudinal axis of the bridge, released from the assembly, and coupled to the already positioned carriages.Two adjacent carrier slides are connected by a sliding bar, with one of the slides being able to be clamped to the sliding bar by means of a clamping device. The machining heads are in the form of slides to which machining tools can be attached.

[0005] EP 3 299 136 A1 discloses a carrier for machining tools for a strip material comprising: a first housing for holding an upper rotating blade and a second housing for holding a lower rotating blade such that the two blades can work together to machine a strip material running between the first and the second blade; a connecting area which is connected to the first and second housings; two bearings with which the carrier can be movably arranged on two parallel linear guides.

[0006] Especially when one or more tools have to work together on both sides of the strip material to process it, the highest possible stability of a tool carrier is required. Description of the invention

[0007] The object of the invention is to create a carrier belonging to the aforementioned technical field, which enables a stable fastening of processing tools which are arranged on both sides of a strip material and cooperate to process the strip material.

[0008] The solution to the problem is defined by the features of claim 1. According to the invention, the carrier for processing tools for a strip material comprises a first arm with a first end and a second end, and a first mounting area for an upper processing tool, wherein the first mounting area is arranged in the region of the first end of the first arm. The carrier further comprises a second arm, which is arranged parallel to the first arm and at a first distance from it, wherein the second arm has a third and a fourth end, and a second mounting area for a lower processing tool, wherein the second mounting area is arranged in the region of the third end of the second arm, such that the upper processing tool and the lower processing tool can interact to process a strip material running between the first arm and the second arm.Furthermore, the carrier has a connecting arm which is connected to the second end of the first arm and to the fourth end of the second arm, as well as a first slide and a second slide with which the carrier can be movably arranged on two parallel linear guides, with the first slide being arranged on the first arm and the second slide being arranged on the second arm.

[0009] Due to the arrangement of the two arms and the connecting arm according to the invention, the carrier essentially has the shape of a C, with the interacting machining tools located on the upper and lower arms of the C. This provides particularly good stability of the carrier. In addition, forces acting on the tools can be reduced. <räfte, welche z. B. beim Aufeinanderpressen der Bearbeitungswerkzeuge oder Teilen davon bei der Bearbeitung des Bandmaterials entstehen, optimal abgeleitet werden bzw. können sich die I<räfte gegenseitig aufheben. Durch die Anordnung von zwei Schlitten an den zwei Armen werden die Gewichtskräfte der Bearbeitungswerkzeuge sowie auf diese wirkende externe I<räfte, welche z. B. beim Bearbeiten des Bandmaterials entstehen, auf die Linearführungen optimal abgeführt, ohne dass sich dabei der Träger verbiegt oder verwindet.

[0010] The processing tools that can be attached to the carrier are preferably punching tools and / or forming tools for shaping the strip material in three dimensions. Alternatively, other processing tools, such as pressing tools, can also be attached to the carrier.

[0011] The strip material processed with the processing tools is preferably a metal, paper, cardboard, or plastic strip. The thickness of the strip material can vary, but is preferably in the range of 0.1 mm to 10 mm.

[0012] The support preferably consists of a metal or a metal alloy, in particular aluminum, steel, or stainless steel. Alternatively, however, the support consists of a plastic, in particular a fiber-reinforced plastic, wherein the plastic is reinforced with glass or I <ohlestofffasern aufweisen kann. Die Arme sowie der Verbindungsarm sind vorzugsweise miteinander verschweisst oder verschraubt. Alternativ kann der Arm jedoch auch einstückig ausgebildet sein.

[0013] The first and second mounting areas preferably each have at least one fastening element with which a machining tool can be attached to the arm. This at least one fastening element can be designed in different ways, e.g., in the form of a bore, an I-shaped hole, or a screw hole. <upplung, eines Hakens, eines Stifts oder dergleichen. Die Befestigungsbereiche können auch über mehrere Befestigungselemente verfügen, welche auch unterschiedlich ausgestaltet sein können. Vorzugsweise weisen die Befestigungsbereiche I<upplungen auf, welche insbesondere werkzeugfrei gelöst und geschlossen werden können, damit der Träger schnell und einfach für eine andere Bearbeitung des Bandmaterials umgerüstet werden kann.

[0014] The first distance is preferably fixed and non-adjustable on the support, and is selected to ensure optimal interaction of the machining tools intended for attachment to the support. This first distance preferably corresponds to the length of the connecting arm. Alternatively, the support may preferably have adjustment means to change the first distance. This allows for greater flexibility in the use of the support.

[0015] The first arm is preferably positioned above the second arm when the carrier is used as intended, with the connecting arm preferably oriented vertically. Depending on the application of the carrier or the orientation of the belt material, other orientations are also possible, e.g., a horizontal orientation of the connecting arm, with the first and second arms arranged horizontally on either side of the connecting arm.

[0016] The connecting arm can be straight or preferably have at least one I <nick oder über mindestens einen Bogen verfügen.

[0017] The two arms and the connecting arm can be any combination of the expected forces acting upon them. <räfte angepasste Querschnitte und Dimensionen aufweisen. Die zwei Arme sowie der Verbindungsarm sind vorzugsweise Profile, insbesondere L-, H- oder U-Profile. Die Verwendung von Profilen ermöglicht eine hohe Steifheit der Arme und des Verbindungsarms bei gleichzeitig geringem Gewicht.

[0018] The first and second arms are preferably of equal length, i.e., the distance between the first and second ends is the same as the distance between the third and fourth ends. Alternatively, however, the two arms can be of different lengths, i.e., the distance between the first and second ends differs from the distance between the third and fourth ends. In a preferred embodiment, the second arm, which is located at the bottom, is longer than the first arm.

[0019] In addition to their normal horizontal extension, the first and / or second arm can also extend vertically, that is, in a direction perpendicular to the extension of the arms between the first and second or third and fourth ends. The vertical extension of the first and / or second arm can be constant along its entire length or vary along its length. This allows the shape of the arms to be adapted in both horizontal and vertical directions, for example, to create sufficient space for arranging additional components such as slides and machining tools.

[0020] The first and second slides preferably have at least one roller or at least one wheel with which the slides rest on the linear guide. Alternatively, the slides can also have sliding bearings. Accordingly, the linear guides of a device on which the carrier is mounted will also have appropriate means to accommodate and guide the at least one roller, at least one wheel, or at least one sliding bearing, in particular via a groove, rail, or counter bearing.

[0021] Preferably, the first slide and the second slide are designed such that the carrier can be moved transversely to the direction of extension of the first arm and the second arm on two linear guides.

[0022] As a result, the two arms of the support protrude from the linear guides on which the support is arranged, particularly at right angles.

[0023] The carrier preferably has an I <opplungseinrichtung angebracht, mit der sich der Träger selektiv mit einer parallel zu den zwei Linearführungen, auf denen die zwei Schlitten beweglich angeordnet werden können, beweglichen Schubstange gekoppelt werden kann, so dass der Träger im gekoppelten Zustand durch die Schubstange entlang der zwei Linearführungen bewegt werden kann.

[0024] Through I <oppeln mit der Schubstange kann der Träger somit durch diese entlang der zwei Linearführungen bewegt werden. Durch selektives Abkoppeln des Trägers von der Schubstange kann dieser an einer bestimmten Position entlang der beiden Linearführungen positioniert werden, ohne durch weitere Bewegungen der Schubstange bewegt zu werden. Ein derartiges selektives System kann beispielsweise verwendet werden, um bei der Anordnung von mehreren Trägern an einer Vorrichtung den Abstand zwischen den Trägern zu verändern oder je nach Bearbeitung des Bandmaterials einzelne Träger, deren Bearbeitungswerkzeuge nicht eingesetzt werden müssen, unbeweglich an einer Parkposition stehen zu belassen.

[0025] The I <opplungseinrichtung ist vorzugsweise als Stangenklemmung ausgeführt. Die Stangenklemmung verfügt vorzugsweise über eine Durchführungsöffnung, durch welche eine Schubstange durchgeführt werden kann. Innerhalb der Durchführungsöffnung ist vorzugsweise mindestens ein Klemmelement angeordnet, welches selektiv mittels eine Aktuators auf eine durch die Durchführungsöffnung durchgeführte Schubstange gedrückt werden kann, um die Schubstange in der Durchführungsöffnung zu verklemmen.

[0026] In an alternative preferred embodiment, a drive is arranged on the carrier, with which the carrier can be moved along two linear guides on which the two slides can be movably arranged.

[0027] The drive allows the carrier to move automatically along the two linear guides. The drive can be of any suitable form, e.g., hydraulic, electric, or electromechanical. The drive preferably interacts with at least one of the linear guides or with another element of the device to move the carrier along the two linear guides. For example, the drive can have a gear that engages with a rack.

[0028] Preferably the carrier has a hollow shaft which is set in rotation by means of an electric motor, wherein the hollow shaft has at least one pin or an internal thread inside to engage the hollow shaft with a threaded rod.

[0029] This allows for a relatively simple yet very reliable and precise drive system for the carrier. The threaded rod is preferably a component of a device on which the carrier is mounted, and the threaded rod is rigidly attached to the device.

[0030] The carrier preferably has a support arm to which a drag chain can be attached. By attaching a drag chain, cables and / or lines can be routed to the carrier, supplying power, control signals, compressed air and / or a fluid, e.g., a cooling fluid or hydraulic fluid, to machining tools attached to the mounting areas and any drive unit located on the arm.

[0031] The holding arm preferably has plugs, sockets and / or I <upplungen, mit denen die I<abel und / oder Leitungen, die durch die Schleppkette zum Träger geführt werden, mit auf diesem angeordneten I<abeln und / oder Leitungen lösbar verbunden werden können. Dies vereinfacht das Anordnen des Arms an oder das Entfernen des Amrs aus einer Vorrichtung.

[0032] The support arm preferably has fastening means with which a drag chain can be attached to it. The fastening means preferably have an I <upplung oder Aufnahmeöffnung für die Schleppkette auf.

[0033] To lead the I <abel und / oder Leitungen auf dem Träger verfügt dieser vorzugsweise über ein I<abelführungselement, welches sich vorzugsweise vom Haltearm zum ersten Arm sowie zum zweiten Arm erstreckt.

[0034] The holding arm preferably extends in a direction opposite to the direction of extension of the first and second arms. This design ensures that the cable chain does not become entangled in the two arms or the machining tools attached to them. Preferably, the length of the holding arm is selected according to the device on which it is to be mounted, such that the cable chain runs on the side of the linear guides opposite the arms. This prevents the cable chain from running between or becoming trapped between multiple supports on a device.

[0035] Preferably, the carrier has a positioning element with which the carrier can be locked at a position along two linear guides on which the two slides are movably arranged.

[0036] The positioning element allows the carrier to be locked, particularly in a parked position. The positioning element preferably interacts with at least one of the linear guides or with a locking element arranged on at least one of the linear guides to lock the carrier in that position.

[0037] The positioning element is preferably designed as a receptacle which can be releasably locked with a pin, the pin preferably being arranged on at least one of the linear guides. Alternatively, the positioning element can also be designed differently, e.g., as a clamp, brake, or the like. Furthermore, the positioning element can also have a movable element which can selectively interact with one of the linear guides on which the slides are arranged, e.g., by being pressed against it.

[0038] The present application further relates to a device for cutting and / or three-dimensional shaping of a strip material, which comprises at least one carrier according to the description above and two parallel linear guides on which the first slide and the second slide of the at least one carrier are movably arranged.

[0039] Machining tools, in particular punching and / or forming tools, are preferably attached to the two mounting areas of the at least one support. The machining tools work together to produce a shaped part from the strip material, for example, by cutting and then forming it three-dimensionally. For instance, a machining tool with a blade, in particular a circular blade, can be arranged at the first mounting area, while a machining tool with a shearing edge complementary to the blade is arranged at the second mounting area. Both the blade and the shearing edge are preferably movable relative to the strip material and relative to each other by means of a drive mechanism. The machining tools can perform several machining steps when producing a shaped part from the strip material, for example, the aforementioned sequence of cutting and three-dimensional forming.The sequence of processing steps required to work the strip material constitutes a processing cycle. In the previously mentioned example of manufacturing a deep-drawn part, the processing steps of cutting and subsequent three-dimensional forming together therefore form a processing cycle.

[0040] The device preferably comprises a plurality of supports, that is, more than one support, in particular more than 5 supports, preferably 10, 11 or 12 supports. The maximum number of supports that can be arranged on the device is determined by the width of the processed strip material and by the dimensions of the processing tools.

[0041] By moving the carriers along the two parallel linear guides, the distance between the carriers can be adjusted depending on the intended processing operation. Furthermore, it is also possible to move the carriers a specific distance along the two parallel linear guides after each processing cycle to achieve optimal material utilization of the processed strip material. In a preferred embodiment, circular shapes are punched out of a strip material using the device, with each carrier being moved by at least half the diameter of the circular shapes after each processing cycle. This movement ensures the most optimal utilization of the strip material's surface area during the cutting of the circular shapes.After each processing cycle, the strip material is moved by at least half the diameter of the circular molded parts, so that no overlaps occur with already punched-out material during cutting, which would lead to molded parts that are not quite circular and therefore essentially unusable.

[0042] The device preferably comprises a frame on which the two parallel linear guides are mounted. Furthermore, the device preferably includes a control system with which the movement of the carriers along the two parallel linear guides, as well as drives for machining tools attached to the mounting areas of the at least one carrier, can be controlled.

[0043] Preferably, the device has conveying means to feed a belt material between the first and second arms of the at least one support and to move it linearly between them.

[0044] The feeding and movement direction of the belt material preferably extends parallel to the direction of expansion of the first and second arms.

[0045] The conveying means can be designed differently depending on the type of strip material being processed by the device. Preferably, the conveying means has at least one driven roller or cylinder on which the strip material rests. Pairs of rollers or cylinders between which the strip material passes are also possible. More preferably, the device can also have a conveyor belt or a roller belt on which the strip material rests. Alternatively, and more preferably, the conveying means can also be designed as a vacuum belt.

[0046] Preferably, the device has a suspension on which a roll of the tape material can be attached, wherein the tape material is unwound from the roll and fed between the arms of the at least one support.

[0047] Preferably, the conveying means are configured such that a strip material is fed between the first and second arms in the direction of extension and moved linearly between them, the device having at least one cutting element with which the strip material can be cut to length after processing by processing tools attached to the first and second mounting areas.

[0048] This means that the strip material is moved from the first end of the first arm or the third end of the second arm towards the connecting arm. To prevent the strip material or its remnants (e.g., the remaining strip material after cutting out the shaped parts) from accumulating on the connecting arm after processing, the strip material is cut to length by at least one cutting element. The cut pieces of strip material are then conveyed away from the supports via a discharge device, in particular into a waste container.

[0049] The at least one cutting element can cut the strip material to length after each processing cycle by the processing tools; however, preferably the strip material is cut to length by the cutting element after a predefined number of processing cycles, in particular after 2, 3, 4, 5 or more processing cycles.

[0050] The at least one cutting element is preferably designed as a blade which is mounted to be displaceable transversely to the longitudinal direction of the strip material in order to cut the strip material.

[0051] Preferably, the device has a linearly movable push rod or a linearly movable or rigid threaded rod, by means of which the at least one support can be moved along the two linear guides.

[0052] If the device has a linearly movable push rod, the at least one support has an I <opplungseinrichtung auf, mit welcher sich der mindestens eine Träger selektiv mit der Schubstange koppeln lässt. Ist der mindestens eine Träger über die I<opplungseinrichtung mit der Schubstange gekoppelt, so wird dieser bei einer Bewegung der Schubstange mitbewegt.

[0053] If the device has a threaded rod, the at least one support has a drive that interacts with the threaded rod to move the support along the two parallel linear guides. Preferably, in this case, the drive has a hollow shaft in which the threaded rod is received and which interacts with the threaded rod, so that by rotating the hollow shaft relative to the threaded rod, the support can be moved relative to it and along the two parallel linear guides.

[0054] If the threaded rod is movably mounted on the device, all supports attached to the device can be moved simultaneously by moving the threaded rod. In this embodiment, the drive mechanism for the supports is therefore used solely to adjust the distance between them.

[0055] If, on the other hand, the threaded rod is rigidly attached to the device, the drive of the supports can be used to change both the distance between the supports and to move all supports or individual supports along the two parallel linear guides.

[0056] The push rod or movable threaded rod is preferably set in motion in two directions along an axis parallel to the two parallel linear guides by a drive. The drive is preferably hydraulic, pneumatic, electric, or electromechanical. In a preferred embodiment, the push rod or movable threaded rod is connected at one end to a carriage, which is moved linearly by the drive. The drive is or preferably comprises a servo motor or a linear actuator.

[0057] Preferably, in this embodiment, the carriage is connected to the output of an electric motor via a toothed belt. If the device has a movable threaded rod, the threaded rod is preferably mounted in such a way that its movement does not cause it to rotate about its longitudinal axis, as this would otherwise change the distance between the supports arranged on the device.

[0058] Preferably the device has at least one drag chain which is connected to the at least one support, preferably to the holding arm of the at least one support.

[0059] The at least one drag chain can guide cables and / or lines to the carrier, which can supply the machining tools and any drive arranged on the arm with electricity, control signals, compressed air and / or a fluid, e.g. a coolant or hydraulic fluid.

[0060] Preferably, the device has a separate drag chain for each support arranged on it. The at least one drag chain is preferably configured such that it can bend in all three spatial directions. If several supports are arranged on the device and there is a drag chain for each support, the drag chains are preferably arranged side by side in such a way that they do not become entangled with each other, even when the supports move along the two parallel linear guides. Particularly preferably, the drag chains are arranged side by side parallel to the direction of extension of the two parallel linear guides.

[0061] The following describes a method for producing stamped and / or formed parts from a strip material of a defined width using at least two processing tools, which is not part of the present invention. The at least two processing tools are each arranged on a carrier, the at least two carriers being mounted so as to be linearly displaceable along at least one linear guide. In a first step of the method, the strip material is fed to the at least two processing tools in a conveying direction that is perpendicular to the at least one linear guide. The strip material is oriented such that its defined width is parallel to the at least one linear guide.The strip material is then processed in multiple work cycles into a variety of stamped and / or formed parts by cutting and / or three-dimensionally shaping the strip material using at least two processing tools. After each work cycle, the strip material is moved in the conveying direction by a conveying distance greater than the extent of the at least two processing tools in the conveying direction. Within each work cycle, at least one of the carriers is moved linearly at least once along the at least one linear guide, so that the strip material is stamped and / or three-dimensionally shaped across its entire defined width by the at least two processing tools in each work cycle.

[0062] The method is preferably carried out with a device according to the invention as described above. The carriers for the processing tools used in the method preferably correspond to the carriers according to the invention as described above. With the method according to the invention, the strip material can be processed into stamped and / or formed parts across its entire defined width without requiring the number of processing tools necessary to cover the defined width. This means that the processing can be carried out with fewer tools than would be calculated to cover the entire defined width.

[0063] The described method thus enables efficient utilization of the strip material while simultaneously reducing the number of processing tools or tool holders required.

[0064] In each work cycle, the strip material is processed along its entire defined width, meaning that stamped and / or formed parts are produced from the strip material using at least two processing tools across the entire defined width.

[0065] During the working cycle, the at least one carrier can be moved in both directions along the at least one linear guide, with the at least one carrier being moved in each direction at least once. Each movement of the at least one carrier preferably takes place over a predetermined distance, which is greater than the extent of the at least two tools in the direction of the at least one linear guide. This ensures that the strip material is not punched and / or three-dimensionally formed in overlapping areas.

[0066] Preferably, within each work cycle, all of the at least two carriers are moved linearly at least once along the at least one linear guide. This achieves the most efficient processing of the strip material, taking into account all available carriers and the processing tools attached to them.

[0067] The sequence of successive movements of a carrier along the at least one linear guide is preferably not identical in all work cycles. In particular, the direction of the successive movements of each carrier is preferably reversed in every second work cycle. Alternatively, and more preferably, the sequence of movements of a carrier can be identical in every work cycle. A further alternatively, and more preferably, the sequence of movements of a carrier can repeat itself after a certain number of work cycles, such that the sequence repeats, for example, every 2, 3, 4, 5 or more work cycles.

[0068] Preferably, the carriers do not all perform the same sequence of movements per work cycle, but each carrier will preferably perform a specific sequence of movements.

[0069] Preferably, all of the at least two processing tools process the strip material per work cycle, i.e., perform a punching and / or three-dimensional forming operation. Alternatively, preferably, however, only at least one of the at least two processing tools processes the strip material per work cycle.

[0070] Because the movement of each carrier and the processing of the strip material by each processing tool can be different per work cycle, an optimal sequence of movements of the associated carrier can be provided for each possible defined width of the strip material and for each embodiment and dimensioning of the at least two processing tools in each work cycle.

[0071] The described method, which does not belong to the present invention, is preferably controlled by a computer program, which is in particular part of a control system of a device according to the invention or can be electrically connected to it in order to transmit control commands to it.

[0072] Further advantageous embodiments and combinations of features of the invention can be derived from the following detailed description and the entirety of the patent claims. Brief description of the drawings

[0075] The Fig. 1Figure 1 shows a schematic side view of a first embodiment of a carrier 1 according to the invention. The carrier 1 has a first arm 2 with a first and a second end, wherein a first mounting area 5 for attaching an upper machining tool is arranged in the region of the first end. The carrier further has a second arm 3 with a third and a fourth end, wherein a second mounting area 6 for a lower machining tool is arranged in the region of the third end. The second end of the first arm 2 and the fourth end of the second arm 3 are connected to each other via a connecting arm 4. The first arm 2 and the second arm 3 run parallel to each other and are arranged at a first distance from each other. The carrier 1 has a first slide 7, which is arranged on the first arm 2, and a second slide 8, which is arranged on the second arm 3.The carrier 1 can be movably mounted on two parallel linear guides by means of the slides 7, 8. Preferably, processing tools for cutting and / or shaping a strip material into three dimensions are attached to the carrier 1 at the two mounting areas 5, 6. The carrier 1 also includes a holding arm 9, which, in the illustrated embodiment, is attached to the second end of the first arm 2. A cable chain (not shown) can be attached to this arm, for example, to supply the processing tools attached to the mounting areas 5, 6 with control signals, electricity, compressed air, or liquids.

[0076] In the embodiment shown, the first arm 2 is equipped with a rod clamp 46. <opplungseinrichtung angeordnet. Die Stangenklemmung 46 weist eine Durchführungsöffnung 47 auf. Innerhalb der Durchführungsöffnung befindet sich ein Klemmelement (nicht gezeigt), welches selektiv auf eine innerhalb der Durchführungsöffnung 47 durchgeführten Schubstange (nicht gezeigt) gedrückt werden kann, um diese innerhalb der Durchführungsöffnung 47 zu klemmen. Durch das Klemmen der Schubstange wird der Träger 1 selektiv an diese gekoppelt.

As can be clearly seen, the two slides 7, 8 are configured such that the support 1, when arranged on two parallel linear guides 27, 28, is movable at a right angle to the extension of the first arm 2 and the second arm 3. The two linear guides 27, 28, as well as the two slides 7, 8, are arranged offset from each other in both the vertical and horizontal directions. It is clearly visible in the figures that the two arms 2, 3 extend both horizontally and vertically.

[0078] A first machining tool can be attached to the first mounting area 5 on the first arm 7. A second machining tool can be attached to the second mounting area 6, which is located on the second arm 4. The first and second machining tools work together to machine a strip material (not shown) located between them, in particular to cut or three-dimensionally shape it. The two machining tools can be moved by drives 36, 37, 38, in particular to move them towards each other and / or to rotate them.

[0079] In the embodiment shown, the support 1 also has a rod clamp 46, with which the support 1 can be selectively attached to a push rod 22 of a device (see Fig. 4The first arm 2 can be coupled to the linear guides 27, 28 to move along them. In the illustrated embodiment, the rod clamp has a pneumatic drive 47, which enables selective clamping of the carrier 1 with the push rod 22. At the second end of the first arm 2, the holding arm 9 is attached, to which a cable carrier (not shown) can be attached, for example, to supply the machining tools or their drives 36, 37, 38 attached to the mounting areas 5, 6 with control signals, electricity, compressed air, or liquids.

[0080] To handle lines and / or I <abel vom Haltearm zu den Bearbeitungswerkzeugen bzw. deren Antrieben 36, 37, 38 zu führen, verfügt der Träger über eine erste I<abelführung 10 sowie über eine zweite I<abelführung 11. Die erste I<abelführung 10 dient dazu, Kabel und / oder Leitungen vom Haltearm 9 zum ersten Bearbeitungswerkzeug bzw. dessen erster Antrieb 36 zu führen. Die zweite I<abelführung 11 dient dazu, Kabel und / oder Leitungen vom Haltearm 9 zum zweiten Bearbeitungswerkzeug bzw. dessen zweiter Antrieb 37 und dritter Antrieb 38 zu führen.

[0081] The Fig. 4Figure 20 shows a device 20 according to the invention with several supports 1.1 - 1.n. ​​The device 20 has a frame 21, on which the device 20 stands on the ground and to which the individual components of the device 20 are attached. The device 20 further comprises two linear guides 27, 28 arranged parallel to each other and spaced a certain distance apart. The supports 1.1 - 1.n are each movably arranged on the two parallel linear guides 27, 28 by means of their two slides 7, 8. The supports 1.1 - 1.n can be moved along the linear guides 27, 28 by means of a push rod 26 which is movably arranged on the frame 21 of the device 20 and is parallel to the linear guides 27, 28. Each of the individual supports 1.1 - 1.n is selectively controlled by a <opplungseinrichtung mit der Schubstange koppelbar, wobei die I<opplungseinrichtungen als Stangenklemmung 46 ausgeführt sind.Thus, one, several or even all carriers 1.1 - 1.n can be by I <oppeln mit der Schubstange 26 bewegt werden. Die Schubstange 26 ist an einem Ende auf einem Wagen 24, welcher auf einem Ausleger 22 des Gestells 21 linear beweglich angeordnet ist, befestigt. Der Wagen 24 ist hierbei parallel zu den Linearführungen 27, 28 beweglich. Ein Motor 23, der vorzugsweise als Elektromotor ausgestaltet ist, ist über einen Zahnriemen 25 mit dem Wagen 24 verbunden, so dass der Wagen 24 mittels des Motors 23 hin und her bewegt werden kann. Je nach Anwendung kann die Vorrichtung 20 über eine unterschiedliche Anzahl an Trägern 1.1 - 1.n verfügen. Die Vorrichtung 20 wird vorzugsweise zum Schneiden und / oder dreidimensionalen Schneiden von Formteilen aus einem Bandmaterial eingesetzt.

[0082] The Fig. 5Figure 1 shows the interaction of an embodiment of a positioning element 40 with a locking element 41. In the embodiment shown, the positioning element 40 is arranged on the first arm 2, while the locking element 41 is attached to a linear guide, in this embodiment to the first linear guide 27. Alternatively, the locking element 41 can also be attached to another component of the device 20, in particular the frame 21. The locking element 41 has a positioning pin 42, which can be moved from a retracted state (not shown) to the extended state shown. In the embodiment shown, the positioning pin 42 engages in a bore 44 of the positioning element 40. The bore 44 is cylindrical and has a conical opening to enable automatic centering of the positioning pin 42 within the bore 44.The positioning pin 42 is moved linearly by means of an actuator 43, in particular a pneumatic actuator, and is pre-tensioned to the extended state by means of a spring element (not shown) which is arranged inside the locking element 41.

[0083] The Fig. 6Figure 1 schematically shows another embodiment of a carrier 1 according to the invention with a drive 48, which is partially arranged on the first arm 2 and on the support arm 9. In the embodiment shown, the drive 48 comprises a motor 49, in particular an electric motor, which can rotate a hollow shaft 50 via a worm gear 51. The hollow shaft 50 has a cylindrical through-opening 52 into which a threaded rod (not shown) can be inserted. The hollow shaft 50 has at least one pin or an internal thread (both not shown) within the cylindrical through-opening 52, which can engage with the threaded rod. By rotating the hollow shaft 50 by means of the motor 49, the carrier 1 can therefore be moved along a threaded rod received in the cylindrical through-opening.
