Description

Technical field

[0001] The invention relates to a cutting device for cutting wire, in particular for cutting cross wires for a welding system, especially a mesh welding system. The cutting device has at least one cutting bushing with a first opening for guiding a first wire to be cut and a second opening for guiding a second wire to be cut, wherein the first opening has a first internal dimension and the second opening has a second internal dimension different from the first internal dimension, wherein the cutting bushing is adjustable to a first processing position for cutting the first wire, which may be guided in the first opening, and to a second processing position for cutting the second wire, which may be guided in the second opening.Furthermore, the cutting device has a blade for cutting the first wire and the second wire, the blade being movable relative to the cutting sleeve in order to cut the first wire in the first operating position of the cutting sleeve when the first wire is guided in the first opening of the cutting sleeve, and to cut the second wire in the second operating position of the cutting sleeve when the second wire is guided in the second opening of the cutting sleeve. The cutting device also has a drive mechanism. State of the art

[0002] Cutting devices for cutting wire, belonging to the aforementioned technical field, are known. For example, EP 3 292 933 B1 of Schlatter Industries AG describes such a cutting device. This device is for cutting cross wires for a mesh welding system. The described cutting device has two cutting bushings. Each cutting bushing has a first opening for guiding a first wire to be cut and a second opening for guiding a second wire to be cut. In each cutting bushing, the first opening has a first internal dimension, and the second opening has a second internal dimension that differs from the first.The two cutting guides are each adjustable to a first processing position for cutting the first wire (which may be guided in the first opening) and to a second processing position for cutting the second wire (which may be guided in the second opening). Furthermore, the described cutting device has a blade for cutting the first and second wires, the blade being movable relative to the two cutting guides. In the first processing position of each cutting guide, when the first wire is guided in the first opening, the blade cuts the first wire. In the second processing position of each cutting guide, when the second wire is guided in the second opening, the blade cuts the second wire.Furthermore, the cutting device described in EP 3 292 933 B1 has a drive for powering the movement of the knife relative to the two cutting bushings in order to cut the respective first and second wires. In addition, the cutting device has a further drive for moving the cutting bushings from their first machining position to their second machining position and back again by means of a worm gear.

[0003] Such well-known cutting devices have the disadvantage of being comparatively complex in design and therefore expensive to manufacture. Furthermore, their complex construction makes them prone to malfunctions and failures. Description of the invention

[0004] The object of the invention is to create a cutting device belonging to the aforementioned technical field for cutting wire, in particular for cutting cross wires for a welding system, especially a mesh welding system, which is simpler and therefore more cost-effective in design and enables more reliable operation of the cutting device.

[0005] The solution to the problem is defined by the features of claim 1. According to the invention, the cutting device has at least one cutting sleeve with a first opening for guiding a first wire to be cut and a second opening for guiding a second wire to be cut, wherein the first opening has a first internal dimension and the second opening has a second internal dimension that differs from the first internal dimension. Preferably, the first wire has a first diameter that is slightly smaller than the first internal dimension of the first opening, so that the first wire can be pushed through the first opening with essentially no play and guided within the first opening.Furthermore, the second wire preferably has a second diameter that is slightly smaller than the second inner dimension of the second opening, so that the second wire can be pushed through and guided within the second opening with virtually no play. Alternatively, the first diameter of the first wire can be dimensioned differently. Likewise, the second diameter of the second wire can also be dimensioned differently.

[0006] According to the invention, the cutting die is adjustable to a first processing position for cutting the first wire, which may be guided in the first opening, and to a second processing position for cutting the second wire, which may be guided in the second opening. Preferably, the cutting die is adjustable from the first processing position to the second processing position and from the second processing position to the first processing position.

[0007] According to the invention, the cutting device comprises a blade for cutting the first wire and the second wire, wherein the blade is movable relative to the cutting sleeve in order to cut the first wire in the first operating position of the cutting sleeve when the first wire is guided in the first opening of the cutting sleeve, and to cut the second wire in the second operating position of the cutting sleeve when the second wire is guided in the second opening of the cutting sleeve. During operation of the cutting device, both a first wire and a second wire can be guided in the first opening and a second wire in the second opening, respectively. However, this is not mandatory. Thus, it is possible that during operation of the cutting device, only a first wire is guided in the first opening for cutting, or that only a second wire is guided in the second opening for cutting.Thus, the cutting device can be designed such that only either a first wire or a second wire can be guided in the second opening at any given time. However, the cutting device can also be designed so that, during operation, both a first wire and a second wire can be guided in the second opening simultaneously. It is therefore essential that the blade is suitable for cutting the first wire, if present in the first opening, when the cutting sleeve is in the first processing position, and suitable for cutting the second wire, if present in the second opening, when the cutting sleeve is in the second processing position.

[0008] According to the invention, the cutting device has a drive. Preferably, the drive is a motor, in particular an electric motor. However, the drive can also be of a different design.

[0009] Regardless of whether the drive is a motor or not, the drive preferably allows the cutting bushing to be adjusted both from the first machining position to the second machining position and from the second machining position to the first machining position. However, it is also possible that the drive allows the cutting bushing to be adjusted only from the first machining position to the second machining position, but not from the second machining position to the first machining position. Likewise, it is also possible that the drive allows the cutting bushing to be adjusted only from the second machining position to the first machining position, but not from the first machining position to the second machining position.If the drive allows the cutting bushing to be adjusted only from the first machining position to the second machining position, but not from the second machining position to the first machining position, then the adjustment of the cutting bushing from the second machining position to the first machining position can be achieved, for example, by a spring return or similar mechanism.

[0010] If, however, the drive only allows the cutting bushing to be adjusted from the second machining position to the first machining position, but not from the first machining position to the second machining position, then the adjustment of the cutting bushing from the first machining position to the second machining position can be achieved, for example, by a spring return or similar mechanism.

[0011] According to the invention, the drive also enables the movement of the knife relative to the cutting bushing to be driven in order to cut the first wire by moving the knife relative to the cutting bushing when the cutting bushing is in the first processing position and the first wire is guided in the first opening, and to cut the second wire by moving the knife relative to the cutting bushing when the cutting bushing is in the second processing position and the second wire is guided in the second opening.

[0012] Both the movement of the knife relative to the cutting die—to cut the first wire when the cutting die is in the first working position and the first wire is guided in the first opening, and to cut the second wire when the cutting die is in the second working position and the second wire is guided in the second opening—and the movement of the cutting die from the first to the second working position and / or from the second to the first working position require a drive capable of delivering a minimal amount of power to successfully perform the movement or adjustment. Such drives, which can reliably deliver this minimal power without malfunctions or failures, are comparatively expensive.By using the same drive both for powering the movement of the knife relative to the cutting bushing, in order to cut the first wire when the cutting bushing is in the first processing position and the first wire is guided in the first opening, and to cut the second wire when the cutting bushing is in the second processing position and the second wire is guided in the second opening, as well as for powering the adjustment of the cutting bushing from the first processing position to the second processing position and / or from the second processing position to the first processing position, a second such drive can be saved.This means that even if a comparatively more expensive but more reliable drive is used, the cutting device can be designed more cost-effectively. At the same time, it also allows for a simpler design of the cutting device. Therefore, the solution according to the invention has the advantage that the cutting device can be designed more simply and thus more cost-effectively, while simultaneously enabling more reliable operation of the cutting device.

[0013] The cutting device according to the invention is preferably used in a wire feeding device for a welding system for welding wire, in particular for a mesh welding system for welding wire to mesh. Accordingly, a wire feeding device for a welding system for welding wire, in particular for a mesh welding system for welding wire to mesh, advantageously comprises at least one cutting device according to the invention.

[0014] Naturally, the cutting device according to the invention can also be manufactured, distributed and operated independently of such a wire feeding device and thus separately from such a wire feeding device.

[0015] The cutting device according to the invention is preferably used in a welding system for welding wire, in particular a mesh welding system for welding wire to mesh. Accordingly, a welding system for welding wire, in particular a mesh welding system for welding wire to mesh, advantageously comprises a cutting device according to the invention, in particular a wire feeding device as mentioned above with a cutting device according to the invention.

[0016] Of course, the cutting device according to the invention can also be manufactured, distributed and operated independently of such a welding system or mesh welding system and thus separately from such a welding system or mesh welding system.

[0017] Advantageously, the cutting device according to the invention is used in a method for cutting wire. In a corresponding method for cutting wire with a cutting device according to the invention, in particular a wire feed device mentioned above, with a cutting device according to the invention, in particular a welding system, in particular a mesh welding system, with a cutting device according to the invention, in particular with a wire feed device mentioned above, with a cutting device according to the invention, the cutting bushing of the cutting device is in the first processing position or the cutting bushing of the cutting device is moved into the first processing position by the drive of the cutting device and, when the cutting bushing is in the first processing position, a first wire to be cut is guided in the first opening of the cutting bushing.or the cutting sleeve of the cutting device is in the second processing position, or the cutting sleeve of the cutting device is moved into the second processing position by the drive of the cutting device, and when the cutting sleeve is in the second processing position, a second wire to be cut is guided in the second opening of the cutting sleeve, after which the knife of the cutting device is moved relative to the cutting sleeve of the cutting device by the drive of the cutting device, whereby, when the cutting sleeve is in the first processing position and the first wire is guided in the first opening of the cutting sleeve, the first wire is cut, and when the cutting sleeve is in the second processing position and the second wire is guided in the second opening in the cutting sleeve, the second wire is cut.

[0018] In a preferred embodiment of this method, the first wire has a cross-section corresponding to the first internal dimension, so that the first wire can be guided in the first opening of the cutting die with essentially no play, and the second wire has a cross-section corresponding to the second internal dimension, so that the second wire can be guided in the second opening of the cutting die with essentially no play. This has the advantage that the cutting device can be operated very efficiently and reliably.

[0019] Alternatively, the diameter of the first wire can be different. Similarly, the diameter of the second wire can also be different.

[0020] In the cutting device according to the invention, the movement of the knife relative to the cutting bushing, which can be driven by the drive, is advantageously a movement of the knife along an adjustment path relative to the cutting bushing, in order to cut the first wire when the cutting bushing is in the first processing position and the first wire is guided in the first opening, and to cut the second wire when the cutting bushing is in the second processing position and the second wire is guided in the second opening, wherein the adjustment path is limited in a first and in a second direction.This has the advantage that the movement of the knife relative to the cutting bushing, driven by the drive, can be optimally controlled and reliably designed to cut the first wire when the cutting bushing is in the first processing position and the first wire is guided in the first opening, and to cut the second wire when the cutting bushing is in the second processing position and the second wire is guided in the second opening.

[0021] Preferably, when the cutting die is in the first processing position and the first wire is guided in the first opening, the first wire can be cut by moving the blade relative to the cutting die in the first direction along the adjustment path, and when the cutting die is in the second processing position and the second wire is guided in the second opening, the second wire can be cut by moving the blade in the first direction along the adjustment path relative to the cutting die, after which the blade can be moved back in the second direction along the adjustment path relative to the cutting die, in particular driven back by the drive, in order to then be moved again in the first direction along the adjustment path to cut the first wire or the second wire again.This has the advantage that the I occurring when moving the knife relative to the cutting bushing <räfte unabhängig vom abzuschneidenden Draht bei der Bewegung in die erste Richtung grösser als bei der Bewegung in die zweite Richtung sind. Entsprechend kann die Schneidvorrichtung einfacher derart ausgebildet werden, dass die Bewegung des Messers relativ zur Schnittbüchse zuverlässig und robust antreibbar ist, um, wenn sich die Schnittbüchse in der ersten Bearbeitungsstellung befindet und der erste Draht in der ersten Öffnung geführt ist, durch die Bewegung des Messers relativ zur Schnittbüchse den ersten Draht abzuschneiden und, wenn sich die Schnittbüchse in der zweiten Bearbeitungsstellung befindet und der zweite Draht in der zweiten Öffnung geführt ist, durch die Bewegung des Messers relativ zur Schnittbüchse den zweiten Draht abzuschneiden. Um dies zu erreichen, kann beispielsweise der Antrieb entsprechend ausgebildet werden.If the cutting device has, for example, a cutting drive coupling arrangement as described below, this cutting drive coupling arrangement can also be designed accordingly.

[0022] Alternatively to these variants, it is also possible that the movement of the knife relative to the cutting bushing, driven by the drive, in order to cut the first wire when the cutting bushing is in the first processing position and the first wire is guided in the first opening, and to cut the second wire when the cutting bushing is in the second processing position and the second wire is guided in the second opening, is not a movement of the knife along an adjustment path relative to the cutting bushing, where the adjustment path is limited in a first and a second direction.

[0023] Advantageously, the cutting bushing can be rotated about a cutting bushing axis from the first machining position to the second machining position and from the second machining position back to the first machining position. Thus, the cutting bushing can be adjusted by rotating it about the cutting bushing axis both from the first machining position to the second machining position and from the second machining position back to the first machining position. The cutting bushing axis is a geometric axis. However, the cutting bushing axis can also be a physical axis.

[0024] In a preferred alternative, the cutting bushing is movable from the first machining position to the second machining position and from the second machining position to the first machining position. Preferably, the cutting bushing is thus adjustable by moving it both from the first machining position to the second machining position and from the second machining position to the first machining position.

[0025] Regardless of whether the cutting bushing is rotatable about the cutting bushing axis from the first machining position to the second machining position and from the second machining position to the first machining position, and thus adjustable by rotating about the cutting bushing axis from both the first machining position to the second machining position and from the second machining position to the first machining position, or whether the cutting bushing is displaceable from the first machining position to the second machining position and from the second machining position to the first machining position, and thus adjustable by displacing both from the first machining position to the second machining position and from the second machining position to the first machining position, the cutting device preferably comprises at least one detent arrangement.to lock the cutting bushing in the first machining position and thereby hold it in that position, and to lock the cutting bushing in the second machining position and thereby hold it in that position. Such a locking arrangement has the advantage that the cutting bushing can be reliably held in both the first and second machining positions in a simple manner. Such a locking arrangement can, for example, consist of a locking notch arranged on the cutting bushing and a spring-loaded lever located on the bearing of the cutting bushing, for example, on the cutting bushing carrier described below. <ugel aufweisen, welche I<ugel in der Rastkerbe einrasten kann, wenn sich die Schnittbüchse in der ersten Bearbeitungsstellung bzw. in der zweiten Bearbeitungsstellung befindet.,

[0026] Alternatively, the cutting device does not include a locking arrangement to lock the cutting bushing into the first machining position and thereby hold it in the first machining position.

[0027] The cutting device advantageously has a cutting drive coupling arrangement by which the drive, the knife and the cutting bushing can be coupled to each other or are coupled to each other in order to drive the movement of the knife relative to the cutting bushing with the drive when the drive, the knife and the cutting bushing are coupled to each other by the cutting drive coupling arrangement and thereby or by this movement, in particular along the adjustment path, when the cutting bushing is in the first processing position and the first wire is guided in the first opening, to cut the first wire and when the cutting bushing is in the second processing position and the second wire is guided in the second opening, to cut the second wire.

[0028] By incorporating this cutting drive coupling arrangement, the drive, the blade, and the cutting bushing can be coupled to each other in a simple and reliable manner. The drive then powers the movement of the blade relative to the cutting bushing, thereby cutting the first wire when the cutting bushing is in the first working position and the first wire is guided in the first opening. Similarly, when the cutting bushing is in the second working position and the second wire is guided in the second opening, the second wire is cut. To achieve this, the drive and the cutting bushing can, for example, be arranged on the same first element, with the drive then moving the blade relative to this first element.In this example, the cutting drive coupling assembly comprises this first element as well as the connection of the drive to the blade, enabling the blade to move relative to the first element and thus relative to the cutting bushing. In another example, the drive and the blade are arranged on an identical second element, with the drive enabling the cutting bushing to move relative to this second element. In this example, the cutting drive coupling assembly comprises this second element as well as the connection of the drive to the cutting bushing, enabling the cutting bushing to move relative to the second element and thus relative to the blade.

[0029] In one variant, the drive, the blade, and the cutting bushing can be coupled together by the cutting drive coupling arrangement in order to drive the movement of the blade relative to the cutting bushing as described above, thereby cutting the first wire or the second wire. In another variant, the drive, the blade, and the cutting bushing can be decoupled from each other by the cutting drive coupling arrangement. This means that when the drive, the blade, and the cutting bushing are decoupled, the movement of the blade relative to the cutting bushing cannot be driven by the drive, so that even if the cutting bushing is in the first processing position and the first wire is guided in the first opening, the first wire is not cut, and even if the cutting bushing is in the second processing position and the second wire is guided in the second opening, the second wire is not cut.This variant has the advantage that, despite the drive being active, movement of the knife relative to the cutting bushing can be prevented by decoupling the drive, the knife, and the cutting bushing using the cutting drive coupling arrangement. This can be advantageous, for example, if the drive is to move the cutting bushing from the first machining position to the second machining position or from the second machining position to the first machining position, and if the knife should not move relative to the cutting bushing during this process.

[0030] In a preferred alternative, however, the drive, the blade, and the cutting bushing cannot be decoupled from each other by the cutting drive coupling arrangement. This has the advantage that the cutting drive coupling arrangement, and thus also the cutting device, can be designed more simply, less prone to failure, and therefore more reliably.

[0031] Preferably, the cutting drive coupling arrangement comprises a cutting bushing carrier and a knife carrier movable relative to the cutting bushing carrier, wherein the cutting bushing is arranged on the cutting bushing carrier and the knife is arranged on the knife carrier, wherein the drive is arranged on a first carrier of the cutting bushing carrier and the knife carrier and is coupled to a second carrier of the cutting bushing carrier and the knife carrier in order to drive a movement of the knife carrier relative to the cutting bushing carrier with the drive and thus drive the movement of the knife relative to the cutting bushing with the drive and therebyThis movement, particularly along the adjustment path, cuts the first wire when the cutting bushing is in the first processing position and the first wire is guided in the first opening, and cuts the second wire when the cutting bushing is in the second processing position and the second wire is guided in the second opening. The statement that the drive is arranged on a first support of the cutting bushing support and the knife support and is coupled to a second support of the cutting bushing support and the knife support means that if the cutting bushing support is the first support of the cutting bushing support and the knife support, the second support of the cutting bushing support and the knife support is the knife support.If, on the other hand, the knife carrier is the first carrier of the cutting box carrier and the knife carrier, then the second carrier of the cutting box carrier and the knife carrier is the cutting box carrier.

[0032] By having a cutting bushing carrier and a knife carrier movable relative to the cutting bushing carrier in the cutting drive coupling arrangement as explained above, the advantage is achieved that the cutting drive coupling arrangement can be constructed robustly in a simple way.

[0033] Preferably, the cutting unit carrier is movably mounted on the knife carrier, or the knife carrier is movably mounted on the cutting unit carrier. In a first embodiment, the cutting unit carrier is slidably mounted on the knife carrier, or the knife carrier is slidably mounted on the cutting unit carrier. In a second embodiment, the cutting unit carrier is pivotably mounted on the knife carrier, or the knife carrier is pivotably mounted on the cutting unit carrier. This has the advantage that the cutting device can be designed compactly. Alternatively, neither the cutting unit carrier nor the knife carrier is movably mounted on the cutting unit carrier. In this case, one or both of the cutting unit carrier and the knife carrier can be movably mounted, in particular slidably or pivotably, on another element of the cutting device.

[0034] Preferably, the blade is fixed to the blade carrier. This has the advantage that the cutting device can be constructed very robustly and that the movement of the blade relative to the cutting bushing can be reliably controlled by mounting the blade carrier movably on another element of the cutting device, such as the cutting bushing carrier. In a variation of this, however, the blade is movably mounted on the blade carrier.

[0035] Regardless of whether the cutting bushing carrier is movably mounted on the knife carrier, whether the knife carrier is movably mounted on the cutting bushing carrier, or whether one or both of the cutting bushing carrier and the knife carrier are movably mounted on another element of the cutting device, the cutting bushing is advantageously mounted on the cutting bushing carrier so that it can be adjusted relative to the cutting bushing carrier from the first machining position to the second machining position and from the second machining position to the first machining position. This has the advantage that the cutting bushing can be held stably in the first machining position and in the second machining position in a simple manner, and yet can still be designed to be adjustable from the first machining position to the second machining position and from the second machining position to the first machining position.

[0036] In a first preferred embodiment, the cutting bushing is rotatably mounted on the cutting bushing carrier about its axis, allowing movement from the first machining position to the second machining position and from the second machining position to the first machining position. That is, in this first preferred embodiment, the cutting bushing can be adjusted by rotating it about its axis, both from the first machining position to the second machining position and from the second machining position to the first machining position. Here, the cutting bushing axis is a geometric axis. However, the cutting bushing axis can also be a physical axis. In a second preferred embodiment, the cutting bushing is slidably mounted on the cutting bushing carrier from the first machining position to the second machining position and from the second machining position to the first machining position., in this second preferred variant, the cutting bushing is adjustable by moving it both from the first machining position to the second machining position and from the second machining position to the first machining position.

[0037] Regardless of whether the cutting bushing is adjustable from the first machining position to the second machining position and from the second machining position to the first machining position on the cutting bushing carrier, the cutting drive coupling arrangement preferably comprises an eccentric disc and a driver. The eccentric disc is preferably rotatably mounted concentrically in a recess of the driver. This means that when the eccentric disc is rotated in the recess of the driver, the center of rotation of the eccentric disc remains unchanged in the same position relative to the recess of the driver due to the concentric mounting. Furthermore, the driver is preferably mounted on the second support of the cutting bushing carrier and the knife carrier so as to be movable, and in particular slidable, in a direction of drive movement relative to the second support of the cutting bushing carrier and the knife carrier.Furthermore, the eccentric disc is preferably arranged eccentrically on the drive and is therefore rotatable eccentrically by the drive. Due to the concentrically rotatable mounting of the eccentric disc in the recess of the driver, the driver can be moved relative to the second support of the cutting bushing carrier and the knife carrier in the direction of the driver's movement by means of the eccentric rotation of the eccentric disc driven by the drive, in the direction of the driver's movement. Moreover, due to the mounting of the driver on the second support of the cutting bushing carrier and the knife carrier, the knife carrier can be moved, in particular displaced, relative to the cutting bushing carrier in a cutting direction, in order to drive the movement of the knife relative to the cutting bushing in the direction of the cutting movement by means of the drive, and thereby...This movement, particularly along the adjustment path, cuts the first wire when the cutting bushing is in the first processing position and the first wire is guided in the first opening, and cuts the second wire when the cutting bushing is in the second processing position and the second wire is guided in the second opening. With this arrangement, the drive is located on the first support of the cutting bushing support and the knife carrier, and is coupled to the second support of the cutting bushing support and the knife carrier via the eccentric slide and the driver, in order to drive the movement of the knife relative to the cutting bushing and thereby...by this movement, especially along the adjustment path, when the cutting bushing is in the first processing position and the first wire is guided in the first opening, to cut the first wire and, when the cutting bushing is in the second processing position and the second wire is guided in the second opening, to cut the second wire.

[0038] Preferably, the cutting motion is oriented essentially perpendicular to the drive motion. In a variant thereof, however, the cutting motion is not oriented essentially perpendicular to the drive motion.

[0039] As an alternative to these variants, it is also possible that the cutting drive coupling arrangement does not include such an eccentric disc and such a driver.

[0040] Preferably, the cutting device has a cutting bushing coupling arrangement by which the drive and the cutting bushing can be coupled together in order to move the cutting bushing from the first machining position to the second machining position, from the second machining position to the first machining position, or from both the first machining position to the second machining position and from the second machining position to the first machining position, when the drive and the cutting bushing are coupled together by the cutting bushing coupling arrangement.Preferably, the drive and the cutting bushing can be decoupled from each other by the cutting bushing coupling arrangement, whereby, when the drive and the cutting bushing are decoupled from each other by the cutting bushing coupling arrangement, the cutting bushing cannot be adjusted from the first machining position to the second machining position and not from the second machining position to the first machining position by the drive.

[0041] This has the advantage that, if the drive and the cutting bushing are decoupled from each other by the cutting bushing coupling arrangement, the drive can be used to move the knife relative to the cutting bushing in order to cut the first wire in the first machining position of the cutting bushing when the first wire is guided in the first opening of the cutting bushing, and to cut the second wire in the second machining position of the cutting bushing when the second wire is guided in the second opening in the cutting bushing, without simultaneously moving the cutting bushing from the first machining position to the second machining position or from the second machining position to the first machining position.

[0042] Advantageously, the cutting device comprises both the cutting drive coupling arrangement and the cutting bushing coupling arrangement. The drive, the blade, and the cutting bushing are preferably coupled to one another by the cutting drive coupling arrangement in order to drive the movement of the blade relative to the cutting bushing with the drive, and thereby, or rather by this movement, particularly along the adjustment path, when the cutting bushing is in the first processing position and the first wire is guided in the first opening, to cut the first wire, and when the cutting bushing is in the second processing position and the second wire is guided in the second opening, to cut the second wire.Furthermore, the drive and the cutting bushing are preferably coupleable to each other by means of the cutting bushing coupling arrangement, in order to move the cutting bushing from the first machining position to the second machining position, from the second machining position to the first machining position, or to move it both from the first machining position to the second machining position and from the second machining position to the first machining position, when the drive and the cutting bushing are coupled to each other by means of the cutting bushing coupling arrangement.Furthermore, the drive and the cutting bushing are preferably decoupled from each other by the cutting bushing coupling arrangement, whereby, when the drive and the cutting bushing are decoupled from each other by the cutting bushing coupling arrangement, the cutting bushing cannot be adjusted from the first machining position to the second machining position and not from the second machining position to the first machining position with the drive.Since in this variant the drive, the blade, and the cutting bushing are coupled to each other by the cutting drive coupling arrangement, the movement of the blade relative to the cutting bushing—to cut the first wire when the cutting bushing is in the first processing position and the first wire is guided in the first opening, and to cut the second wire when the cutting bushing is in the second processing position and the second wire is guided in the second opening—is preferably always driven by the drive. In contrast, the cutting bushing coupling arrangement allows the adjustment of the cutting bushing from the first processing position to the second processing position, or vice versa, to be activated by coupling the drive to the cutting bushing, and deactivated by decoupling the drive from the cutting bushing.This enables simple operation of the cutting device. At the same time, it also allows the cutting device to be designed for particularly reliable operation in a simple manner. Thus, larger forces are at play during the cutting process of the first or second wire. <räfte auf die Schneidvorrichtung als beim Verstellen der Schnittbüchse von der ersten Bearbeitungsstellung in die zweite Bearbeitungsstellung bzw. von der zweiten Bearbeitungsstellung in die erste Bearbeitungsstellung.

Damit reicht eine weniger robust ausgebildete Schnittbüchsenkopplungsanordnung aus.A less robustly designed cutting bushing coupling arrangement is easier to construct in such a way that it can couple the drive to the cutting bushing and decouple it from the cutting bushing. Therefore, such a cutting device can be designed to be particularly reliable in operation.

[0043] In an advantageous embodiment, the drive, the blade, and the cutting bushing are coupled to one another by the cutting drive coupling arrangement in order to drive the movement of the blade relative to the cutting bushing with the drive, and thereby, or rather by this movement, when the cutting bushing is in the first processing position and the first wire is guided in the first opening, to cut the first wire, and when the cutting bushing is in the second processing position and the second wire is guided in the second opening, to cut the second wire. Furthermore, the blade and the cutting bushing are preferably couplingable to one another by the cutting bushing coupling arrangement in order that, when the blade and the cutting bushing are coupled to one another by the cutting bushing coupling arrangement, the movement of the blade relative to the cutting bushing moves the cutting bushing from the first processing position to the second processing position.to adjust from the second machining position to the first machining position, or to adjust both from the first machining position to the second machining position and from the second machining position to the first machining position, wherein the drive and the cutting bushing can be decoupled from each other by the cutting bushing coupling arrangement, whereby, when the knife and the cutting bushing are decoupled from each other by the cutting bushing coupling arrangement, the movement of the knife relative to the cutting bushing does not allow the cutting bushing to be adjusted from the first machining position to the second machining position and not from the second machining position to the first machining position. In this variant, since the drive, the knife, and the cutting bushing are coupled to each other by the cutting drive coupling arrangement,to drive the movement of the knife relative to the cutting bushing with the drive, and thereby or through this movement, in particular along the adjustment path, to cut the first wire when the cutting bushing is in the first processing position and the first wire is guided in the first opening, and to cut the second wire when the cutting bushing is in the second processing position and the second wire is guided in the second opening, by means that the knife and the cutting bushing can be coupled and uncoupled from each other by means of the cutting bushing coupling arrangement, and also the drive and the cutting bushing can be coupled to each other by means of the cutting bushing coupling arrangement, in order to move the cutting bushing from the first processing position to the second processing position, and from the second processing position to the first processing position.or to be moved both from the first machining position to the second machining position and from the second machining position to the first machining position, and the drive and the cutting bushing can be decoupled from each other by the cutting bushing coupling arrangement, whereby, since the knife and the cutting bushing are decoupled from each other by the cutting bushing coupling arrangement, the movement of the knife relative to the cutting bushing does not cause the cutting bushing to be moved from the first machining position to the second machining position and not from the second machining position to the first machining position. This has the advantage that the cutting device can be designed particularly simply.

[0044] Advantageously, the interface coupling arrangement features an I <opplungselement auf, welches I<opplungselement von einer I<opplungsstellung in eine Entkopplungsstellung und von der Entkopplungsstellung in die I<opplungsstellung verstellbar ist, wobei in der I<opplungsstellung des I<opplungselements die Schnittbüchse durch das I<opplungselement mit dem Messerträger gekoppelt ist, wodurch durch die mit dem Antrieb antreibbare Bewegung des Messerträgers relativ zum Schnittbüchsenträger die Schnittbüchse von der ersten Bearbeitungsstellung in die zweite Bearbeitungsstellung verstellbar, von der zweiten Bearbeitungsstellung in die erste Bearbeitungsstellung verstellbar, oder sowohl von der ersten Bearbeitungsstellung in die zweite Bearbeitungsstellung als auch von der zweiten Bearbeitungsstellung in die erste Bearbeitungsstellung verstellbar ist,where in the decoupling position of the I <opplungselements die Schnittbüchse nicht durch das I<opplungselement mit dem Messerträger gekoppelt ist und damit die Schnittbüchse von dem Messerträger entkoppelt ist, wodurch durch die mit dem Antrieb antreibbare Bewegung des Messerträgers relativ zum Schnittbüchsenträger die Schnittbüchse nicht von der ersten Bearbeitungsstellung in die zweite Bearbeitungsstellung und nicht von der zweiten Bearbeitungsstellung in die erste Bearbeitungsstellung verstellbar ist. Dadurch sind in der I<opplungsstellung des I<opplungselements der Antrieb und die Schnittbüchse durch die Schnittbüchsenkopplungsanordnung miteinander gekoppelt, um mit dem Antrieb die Schnittbüchse von der ersten Bearbeitungsstellung in die zweite Bearbeitungsstellung zu verstellen, von der zweiten Bearbeitungsstellung in die erste Bearbeitungsstellung zu verstellen,or to move it from the first processing position to the second processing position as well as from the second processing position to the first processing position. In the decoupling position of the I <opplungselements hingegen sind der Antrieb und die Schnittbüchse durch die Schnittbüchsenkopplungsanordnung voneinander entkoppelt, wodurch mit dem Antrieb die Schnittbüchse nicht von der ersten Bearbeitungsstellung in die zweite Bearbeitungsstellung und nicht von der zweiten Bearbeitungsstellung in die erste Bearbeitungsstellung verstellbar ist.,

[0045] Preferably, the cutting device has two cutting bushings, each having a first opening for guiding a first wire to be cut and a second opening for guiding a second wire to be cut, the first opening having a first internal dimension and the second opening having a second internal dimension different from the first internal dimension, the cutting bushings being adjustable to a first processing position for cutting the first wire, optionally guided in the first opening, and to a second processing position for cutting the second wire, optionally guided in the second opening, the knife being movable relative to the two cutting bushings in order to cut the first wire at a first of the two cutting bushings, when the first wire is guided in the first opening of the first cutting bushing, andin the second processing position of the first cutting die, when the second wire is guided in the second opening in the first cutting die, to cut the second wire, and in a second of the two cutting dies, in the first processing position of the second cutting die, when the first wire is guided in the first opening of the second cutting die, to cut the first wire, and in the second processing position of the second cutting die, when the second wire is guided in the second opening in the second cutting die, to cut the second wire, wherein the drive moves the first cutting die from the first processing position to the second processing position,from the second machining position to the first machining position, or both from the first machining position to the second machining position and both from the second machining position to the first machining position, and the drive allows the second cutting bushing to be adjusted from the first machining position to the second machining position, from the second machining position to the first machining position, or both from the first machining position to the second machining position and both from the second machining position to the first machining position. This allows, depending on the current machining position of the cutting bushings and depending on whether a wire to be cut is guided in the corresponding opening of the respective cutting bushing in only one or both cutting bushings,that with a single movement of the knife relative to the two cutting guides, only the first wire guided in the first opening of the first cutting guide, only the second wire guided in the second opening of the first cutting guide, only the first wire guided in the first opening of the second cutting guide, only the second wire guided in the second opening of the second cutting guide, the first wire guided in the first opening of the first cutting guide as well as the first wire guided in the first opening of the second cutting guide, the first wire guided in the first opening of the first cutting guide as well as the second wire guided in the second opening of the second cutting guide,The second wire guided in the second opening of the first cutting box, as well as the first wire guided in the first opening of the second cutting box, or the second wire guided in the second opening of the first cutting box, as well as the second wire guided in the second opening of the second cutting box, can be cut off.

[0046] Particularly preferred, the two cutting bushings are adjustable by the drive only together from the first machining position to the second machining position, from the second machining position to the first machining position, or both from the first machining position to the second machining position and from the second machining position to the first machining position. Since in this particularly preferred embodiment both cutting bushings are in the first machining position or in the second machining position, only six of the eight wire cutting variants described above are possible with a single movement of the knife relative to the two cutting bushings.Thus, depending on the current processing position of the cutting dies and depending on whether a wire to be cut is guided in the corresponding opening of one or both cutting dies, a single movement of the knife relative to the two cutting dies can cut only the first wire guided in the first opening of the first cutting die, only the second wire guided in the second opening of the first cutting die, only the first wire guided in the first opening of the second cutting die, only the second wire guided in the second opening of the second cutting die, the first wire guided in the first opening of the first cutting die and the first wire guided in the first opening of the second cutting die, or the second wire guided in the second opening of the first cutting die and the second wire guided in the second opening of the second cutting die.

[0047] Regardless of this, the movement of the knife relative to the two cutting bushings, driven by the drive, is such that, in the first processing position of the first cutting bushing, when the first wire is guided in the first opening of the first cutting bushing, the first wire is cut, and, in the second processing position of the first cutting bushing, when the second wire is guided in the second opening of the first cutting bushing, the second wire is cut, as well as, in the second processing position of the second cutting bushing, in the first processing position of the second cutting bushing, when the first wire is guided in the first opening of the second cutting bushing, the first wire is cut, and, in the second processing position of the second cutting bushing, the second wire is cut,a movement of the knife along the adjustment path relative to the two cutting guides, wherein the adjustment path is limited in a first and a second direction.

[0048] Preferably, when the first cutting bushing is in the first processing position and the first wire is guided in the first opening of the first cutting bushing, the first wire can be cut by moving the knife in the first direction along the adjustment path relative to the two cutting bushings, and when the first cutting bushing is in the second processing position and the second wire is guided in the second opening of the first cutting bushing, the second wire can be cut by moving the knife in the first direction along the adjustment path relative to the two cutting bushings.Furthermore, preferably, when the second cutting bushing is in the first processing position and the first wire is guided in the first opening of the second cutting bushing, the first wire can be cut by moving the knife relative to the two cutting bushings in the first direction along the adjustment path, and when the second cutting bushing is in the second processing position and the second wire is guided in the second opening of the second cutting bushing, the second wire can be cut by moving the knife in the first direction along the adjustment path relative to the two cutting bushings, after which the knife can be moved back in the second direction along the adjustment path relative to the two cutting bushings, in particular driven back by the drive, in order to then be moved again in the first direction along the adjustment path to cut the first wire or the second wire again.

[0049] Preferably, the two cutting bushings are each rotatable about a first cutting bushing axis from the first machining position to the second machining position and from the second machining position to the first machining position. Accordingly, the two cutting bushings are preferably each adjustable by rotating about their respective cutting bushing axis both from their respective first machining position to their respective second machining position and from their respective second machining position to their respective first machining position. The two cutting bushing axes are geometric axes. However, one or both of the two cutting bushing axes can also simultaneously be a physical axis.

[0050] In one variation, the two cutting guides are each movable from the first machining position to the second machining position and from the second machining position to the first machining position. Accordingly, the two cutting guides are preferably each adjustable by sliding both from the first machining position to the second machining position and from the second machining position to the first machining position.

[0051] Preferably, the cutting device comprises at least one locking arrangement for locking the two cutting bushings into the first machining position and thereby holding them in that position, and for locking the two cutting bushings into the second machining position and thereby holding them in that position. Such a locking arrangement can, for example, consist of a locking notch arranged on the respective cutting bushing and two spring-loaded contacts arranged on the bearing of the two cutting bushings, for example on the cutting bushing carrier. <ugeln aufweisen, welche I<ugeln jeweils in der Rastkerbe einer anderen der zwei Schnittbüchsen einrasten können, wenn sich die jeweilige Schnittbüchse in der ersten Bearbeitungsstellung bzw. in der zweiten Bearbeitungsstellung befindet.

[0052] Alternatively, the cutting device can also be designed without such a locking arrangement.

[0053] Preferably, the cutting device has the cutting drive coupling arrangement by which the drive, the knife and the two cutting bushings can be coupled to each other or are coupled to each other in order to drive the movement of the knife relative to the two cutting bushings with the drive when the drive, the knife and the two cutting bushings are coupled to each other by the cutting drive coupling arrangement and thereby drive the movement of the knife relative to the two cutting bushings with the drive.by this movement in the first processing position of the first cutting die, when the first wire is guided in the first opening of the first cutting die, to cut the first wire and in the second processing position of the first cutting die, when the second wire is guided in the second opening in the first cutting die, to cut the second wire, as well as in the first processing position of the second cutting die, when the first wire is guided in the first opening of the second cutting die, to cut the first wire and in the second processing position of the second cutting die, when the second wire is guided in the second opening in the second cutting die, to cut the second wire.

[0054] In one variant, the drive, the blade, and the two cutting bushings can be coupled together by the cutting drive coupling arrangement in order to drive the movement of the blade relative to the two cutting bushings as described above, thereby cutting the respective first or second wire. Conversely, the drive, the blade, and the two cutting bushings can be decoupled from each other by the cutting drive coupling arrangement. When the drive, the blade, and the cutting bushings are decoupled, the movement of the blade relative to the cutting bushing cannot be driven by the drive, so that even if the first cutting bushing is in the first processing position and the respective first wire is guided in the first opening of the first cutting bushing, the respective first wire is not cut.even if the first cutting die is in the second processing position and the respective second wire is guided in the second opening of the first cutting die, the respective second wire should not be cut, and even if the second cutting die is in the first processing position and the respective first wire is guided in the first opening of the second cutting die, the respective first wire should not be cut, and even if the second cutting die is in the second processing position and the respective second wire is guided in the second opening of the second cutting die, the respective second wire should not be cut.

[0055] In one variant, however, the drive, the knife and the two cutting bushings cannot be decoupled from each other by the cutting drive coupling arrangement.

[0056] Preferably, the cutting drive coupling arrangement comprises the cutting bushing carrier and the knife carrier movable relative to the cutting bushing carrier, wherein the two cutting bushings are arranged on the cutting bushing carrier and the knife is arranged on the knife carrier, wherein the drive is arranged on a first carrier of the cutting bushing carrier and the knife carrier and is coupled to a second carrier of the cutting bushing carrier and the knife carrier in order to drive the movement of the knife carrier relative to the cutting bushing carrier with the drive and thus drive the movement of the knife relative to the two cutting bushings with the drive and therebyby this movement, in particular along the adjustment path, in the first processing position of the first cutting die, when the first wire is guided in the first opening of the first cutting die, to cut the first wire and, in the second processing position of the first cutting die, when the second wire is guided in the second opening in the first cutting die, to cut the second wire, as well as in the first processing position of the second cutting die, when the first wire is guided in the first opening of the second cutting die, to cut the first wire and, in the second processing position of the second cutting die, when the second wire is guided in the second opening in the second cutting die, to cut the second wire.

In a first preferred embodiment, the two cutting bushings are mounted on the cutting bushing carrier so that they can be rotated about their respective cutting bushing axis from the first machining position to the second machining position and from the second machining position to the first machining position. Accordingly, the two cutting bushings are preferably adjustable by rotating them about their respective cutting bushing axis both from the first machining position to the second machining position and from the second machining position to the first machining position. The two cutting bushing axes are geometric axes.One or both of the two cutting bushing axes can also be a physical axis. In a second preferred embodiment, however, the two cutting bushings are mounted on the cutting bushing carrier so that they can be slid from the first machining position to the second machining position and from the second machining position to the first machining position. Accordingly, the two cutting bushings are preferably adjustable by sliding both from the first machining position to the second machining position and from the second machining position to the first machining position.

[0058] Regardless of whether the two cutting bushings are adjustable from the first machining position to the second machining position and from the second machining position to the first machining position on the cutting bushing carrier or not, the cutting drive coupling arrangement preferably comprises the eccentric disc and the driver, wherein the eccentric disc is rotatably mounted concentrically in a recess of the driver, and wherein the driver is mounted on the second carrier of the cutting bushing carrier and the knife carrier so as to be movable, in particular displaceable, in a direction of drive movement relative to the second carrier of the cutting bushing carrier and the knife carrier, and wherein the eccentric disc is arranged eccentrically on the drive and is therefore rotatable eccentrically by the drive.wherein, due to the concentrically rotatable bearing of the eccentric disc in the recess of the driver, the driver is movable relative to the second support of the cutting bushing carrier and the knife carrier in the direction of the driver movement by means of an eccentric rotation of the eccentric disc driven by the drive, and furthermore, due to the bearing of the driver on the second support of the cutting bushing carrier and the knife carrier, the knife carrier is movable relative to the cutting bushing carrier in a cutting direction, in particular displaceable, in order to drive the movement of the knife relative to the cutting bushing in the cutting direction by means of the drive and thereby, or by means of this movement, in particular along the adjustment path, in the first processing position of the first cutting bushing, when the first wire is guided in the first opening of the first cutting bushing, to cut the first wire and, in the second processing position of the first cutting bushing,When the second wire is guided in the second opening in the first cutting die, cut the second wire; and in the first processing position of the second cutting die, when the first wire is guided in the first opening of the second cutting die, cut the first wire; and in the second processing position of the second cutting die, when the second wire is guided in the second opening in the second cutting die, cut the second wire.

[0059] This means that the drive is arranged on the first support of the cutting bushing support and the knife support and is coupled to the second support of the cutting bushing support and the knife support by means of the eccentric slide and the driver in order to drive the movement of the knife relative to the cutting bushing and thereby orby this movement, in particular along the adjustment path, in the first processing position of the first cutting die, when the first wire is guided in the first opening of the first cutting die, to cut the first wire and, in the second processing position of the first cutting die, when the second wire is guided in the second opening in the first cutting die, to cut the second wire, as well as in the first processing position of the second cutting die, when the first wire is guided in the first opening of the second cutting die, to cut the first wire and, in the second processing position of the second cutting die, when the second wire is guided in the second opening in the second cutting die, to cut the second wire.

[0060] Preferably, the cutting motion is oriented essentially perpendicular to the drive motion. Alternatively, however, it is also possible that the cutting motion is not oriented essentially perpendicular to the drive motion.

[0061] Preferably, the cutting device has a cutter bushing coupling arrangement by which the drive and the two cutter bushings can be coupled to each other, in order to move the two cutter bushings from the first machining position to the second machining position, from the second machining position to the first machining position, or both from the first machining position to the second machining position and from the second machining position to the first machining position, wherein the drive and the two cutter bushings can be decoupled from each other by the cutter bushing coupling arrangement, whereby, when the drive and the two cutter bushings are decoupled from each other by the cutter bushing coupling arrangement,The drive does not allow the two cutting bushings to be adjusted from the first machining position to the second machining position, nor from the second machining position to the first machining position.

[0062] Advantageously, the cutting device comprises both the cutting drive coupling arrangement and the cutting bushing coupling arrangement. The drive, the blade, and the two cutting bushings are preferably coupled to each other by the cutting drive coupling arrangement in order to drive the movement of the blade relative to the two cutting bushings with the drive, and thereby...by this movement, in particular along the adjustment path, in the first processing position of the first cutting die, when the first wire is guided in the first opening of the first cutting die, to cut the first wire and, in the second processing position of the first cutting die, when the second wire is guided in the second opening in the first cutting die, to cut the second wire, as well as in the first processing position of the second cutting die, when the first wire is guided in the first opening of the second cutting die, to cut the first wire and, in the second processing position of the second cutting die, when the second wire is guided in the second opening in the second cutting die, to cut the second wire.Furthermore, the drive and the two cutting bushings are preferably coupled to each other by the cutting bushing coupling arrangement in order to, when the drive and the two cutting bushings are coupled to each other by the cutting bushing coupling arrangement, adjust the two cutting bushings with the drive from the first machining position to the second machining position, adjust them from the second machining position to the first machining position, or adjust them both from the first machining position to the second machining position and from the second machining position to the first machining position.Furthermore, the drive and the two cutting bushings are preferably decoupled from each other by the cutting bushing coupling arrangement, whereby, when the drive and the two cutting bushings are decoupled from each other by the cutting bushing coupling arrangement, the two cutting bushings cannot be adjusted from the first machining position to the second machining position and from the second machining position to the first machining position with the drive.

[0063] Advantageously, the drive, the knife, and the cutting bushing are coupled to each other by the cutting drive coupling arrangement in order to drive the movement of the knife relative to the two cutting bushings with the drive and thereby, or rather by this movement, particularly along the adjustment path, in the first processing position of the first cutting bushing, when the first wire is guided in the first opening of the first cutting bushing, to cut the first wire and, in the second processing position of the first cutting bushing, when the second wire is guided in the second opening of the first cutting bushing, to cut the second wire, as well as in the first processing position of the second cutting bushing, when the first wire is guided in the first opening of the second cutting bushing, to cut the first wire and, in the second processing position of the second cutting bushing,when the second wire is guided in the second opening in the second cutting bushing, to cut the second wire, wherein the knife and the two cutting bushings can be coupled to each other by the cutting bushing coupling arrangement, in order to move the two cutting bushings each from the first machining position to the second machining position, each from the second machining position to the first machining position, or each from both the first machining position to the second machining position and each from the second machining position to the first machining position, and wherein the drive and the two cutting bushings can be decoupled from each other by the cutting bushing coupling arrangement, whereby,If the knife and the two cutting bushings are decoupled from each other by the cutting bushing coupling arrangement, the two cutting bushings cannot be adjusted from the first machining position to the second machining position and vice versa by the movement of the knife relative to the two cutting bushings.

[0064] In this variant, the drive, the knife, and the two cutting bushings are coupled to each other by the cutting drive coupling arrangement in order to drive the movement of the knife relative to the two cutting bushings with the drive, and thereby, or rather through this movement, particularly along the adjustment path, in the first processing position of the first cutting bushing, when the first wire is guided in the first opening of the first cutting bushing, to cut the first wire, and in the second processing position of the first cutting bushing, when the second wire is guided in the second opening of the first cutting bushing, to cut the second wire, and in the first processing position of the second cutting bushing, when the first wire is guided in the first opening of the second cutting bushing, to cut the first wire, and in the second processing position of the second cutting bushing,When the second wire is guided in the second opening in the second cutting bushing, the second wire can be cut by means of the cutting bushing coupling arrangement, the drive and the two cutting bushings can also be coupled to each other by means of the cutting bushing coupling arrangement, in order to move the two cutting bushings from the first machining position to the second machining position, from the second machining position to the first machining position, or from both the first machining position to the second machining position and from the second machining position to the first machining position, and the drive and the two cutting bushings can be decoupled from each other by means of the cutting bushing coupling arrangement, whereby,by decoupling the knife and the two cutting bushings from each other through the cutting bushing coupling arrangement, the two cutting bushings cannot be adjusted from the first machining position to the second machining position and from the second machining position to the first machining position by the movement of the knife relative to the two cutting bushings.

[0067] 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

[0068] The drawings used to illustrate the exemplary embodiment show: Fig. 1a, bje shows an oblique view of a cutting device according to the invention for cutting transverse wires for a mesh welding system and thus for cutting wire; Fig. 2a, bje shows an oblique view of the cutting device from a different perspective than shown in the Figures 1a and 1b, Fig. 3a, leg interior view onto an I <opplung einer Achse mit einem Schnittbüchsenträger der Schneidvorrichtung sowie eine entlang der Achse verlaufende Schnittdarstellung durch die Schneidvorrichtung, Fig. 4a, beine Schrägansicht von zwei Schnittbüchsen der Schneidvorrichtung sowie eine Querschnittsdarstellung durch die zwei im Schnittbüchsenträger gelagerten Schnittbüchsen.

[0069] Basically, identical parts in the figures are marked with the same reference symbols. Ways to implement the invention

[0070] The Figures 1a and 1b Figures 1 and 2 show oblique views of a cutting device 1 according to the invention for cutting wire 50. More precisely, this is a cutting device 1 for cutting cross wires for a mesh welding system. This cutting device 1 can therefore be used in a welding system as well as in a mesh welding system.

[0071] The cutting device 1 has two cutting bushings 2.1, 2.2, each having a first opening 3.1, 3.2 for guiding a first wire 50 to be cut, a second opening 4.1, 4.2 for guiding a second wire to be cut, and a third opening 5.1, 5.2 for guiding a third wire to be cut. The first opening 3.1, 3.2 in each case has a first internal dimension, while the second opening 4.1, 4.2 in each case has a second internal dimension different from the first internal dimension, and the third opening in each case has a third internal dimension different from both the first and second internal dimensions. These cutting bushings 2.1, 2.2 and the openings 3.1, 3.2, 4.1, 4.2, 5.1, 5.2 are in the Figure 4a The two cutting guides 2.1 and 2.2 are, as described below in connection with the Figures 4a and 4bdescribed, adjustable to a first processing position for cutting the first wire 50, which may be guided in the first opening 3.1, 3.2, adjustable to a second processing position for cutting the second wire, which may be guided in the second opening 4.1, 4.2, adjustable to a second processing position, and adjustable to a third processing position for cutting the third wire, which may be guided in the third opening 5.1, 5.2.

[0072] The cutting device 1 further comprises two knives 6.1, 6.2, which are movable relative to the two cutting bushings 2.1, 2.2, in order to cut the first wire 50 in the first processing position of the first cutting bushing 2.1 when the first wire 50 is guided in the first opening 3.1 of the first cutting bushing 3.1, and in the second processing position of the first cutting bushing 2.1 when the second wire is guided in the second opening 4.1 of the first cutting bushing 2.1, and in the third processing position of the first cutting bushing 2.1 when the third wire is guided in the third opening 5.1 of the first cutting bushing 2.1, as well as to cut the third wire in the first processing position of the second cutting bushing 2.2 of the second cutting bushing 2.2, in the first processing position of the second cutting bushing 2.2, when the first wire 50 is in the first opening 3.2 of the second cutting box 2.2 is guided to cut off the first wire 50 and in the second processing position of the second cutting bushing 2.2, when the second wire is guided in the second opening 4.2 in the second cutting bushing 2.2, to cut off the second wire, and in the third processing position of the second cutting bushing 2.2, when the third wire is guided in the third opening 4.2 in the second cutting bushing 2.2, to cut off the third wire.

[0073] The process of cutting a wire with the cutting device 1 is described in the Figures 1a and 1b illustrated. Thus, in the Figure 1a The first wire 50, guided in the first opening 3.1 of the first cutting box 2.1, is shown before the cutting process. Therefore, the corresponding knife 6.1 is located next to the first opening 3.1 of the first cutting box 2.1 and thus next to the first wire 50 guided in the first opening 3.1 of the first cutting box 2.1. In the Figure 1bIn contrast, the knife 6.1 is moved relative to the first cutting box 2.1 in front of the first opening 3.1 of the first cutting box 2.1, thereby cutting off the first wire 50.

[0074] The cutting device 1 also has a drive 7. This drive 7 enables the movement of the two knives 6.1, 6.2 relative to the two cutting bushings 2.1, 2.2 to be driven, in order to cut the first wire 50 by moving one of the knives 6.1 relative to the first cutting bushing 2.1 when the first cutting bushing 2.1 is in the first processing position and the first wire 50 is guided in the first opening 3.1; to cut the second wire 50 by moving one of the knives 6.1 relative to the first cutting bushing 2.1 when the first cutting bushing 2.1 is in the second processing position and the second wire is guided in the second opening 4.1; and to cut the second wire 50 by moving one of the knives 6.1 relative to the first cutting bushing 2.1 when the first cutting bushing 2.1 is in the third processing position and the third wire is guided in the third opening 5.1.1. to cut the third wire and, when the second cutting bushing 2.2 is in the first processing position and the first wire 50 is guided in the first opening 3.2, to cut the first wire 50 by moving the other of the knives 6.2 relative to the second cutting bushing 2.2 and, when the second cutting bushing 2.2 is in the second processing position and the second wire is guided in the second opening 4.2, to cut the second wire by moving the other of the knives 6.2 relative to the second cutting bushing 2.2 and, when the second cutting bushing 2.2 is in the third processing position and the third wire is guided in the third opening 5.2, to cut the third wire by moving the other of the knives 6.2 relative to the second cutting bushing 2.2.

[0075] The movement of the two knives 6.1, 6.2 relative to the two cutting bushings 2.1, 2.2, driven by the drive 7, is such that, in the first of the two cutting bushings 2.1, in the first processing position of the first cutting bushing 2.1, when the first wire 50 is guided in the first opening 3.1 of the first cutting bushing 2.1, the first wire 50 is cut; in the second processing position of the first cutting bushing 2.1, when the second wire is guided in the second opening 4.1 of the first cutting bushing 2.1, the second wire is cut; and in the third processing position of the first cutting bushing 2.1, when the third wire is guided in the third opening 5.1 of the first cutting bushing 2.1, the third wire is cut; and in the second of the two cutting bushings 2.2, in the first processing position of the second cutting bushing 2.2, when the first wire 50 is guided in the third opening 5.1 of the first cutting bushing 2.1, the second wire 50 is cut. the first opening 3.2 of the second cutting box 2.The movement of the two knives 6.1, 6.2 along an adjustment path relative to the two cutting bushes 2.1, 2.2, where the adjustment path is limited in a first and a second direction, is described as follows: 2, to cut the first wire 50; 2, when the second wire is guided in the second opening 4.2 in the second cutting bush 2.2, to cut the second wire; 3, when the third wire is guided in the third opening 5.2 in the second cutting bush 2.2, to cut the third wire; 4, 5, 6 ... Figures 1a and 1b The two knives 6.1, 6.2 are shown at one end position of this adjustment path relative to the two cutting bushings 2.1, 2.2.

[0076] When the first cutting die 2.1 is in the first processing position and the first wire 50 is guided in the first opening 3.1 of the first cutting die 2.1, the first wire 50 can be cut by moving one knife 6.1 relative to the two cutting dies 2.1, 2.2 in the first direction along the adjustment path; when the first cutting die 2.1 is in the second processing position and the second wire is guided in the second opening 4.1 of the first cutting die 2.1, the second wire can be cut by moving one knife 6.1 in the first direction along the adjustment path relative to the two cutting dies 2.1, 2.2; and when the first cutting die 2.1 is in the third processing position and the third wire is guided in the third opening 5.1 of the first cutting die 2.1, the first wire can be cut by moving one knife 6.1 in the first direction along the adjustment path relative to the two cutting dies 2.1, 2.2. Adjustment range relative to the two cutting bushings 2.1, 2.2. The third wire can be cut off. Furthermore, when the second cutting bushing 2.2 is in the first processing position and the first wire 50 is guided in the first opening 3.2 of the second cutting bushing 2.2, the first wire 50 can be cut by the movement of the other knife 6.2 relative to the two cutting bushings 2.1, 2.2 in the first direction along the adjustment path; and when the second cutting bushing 2.2 is in the second processing position and the second wire is guided in the second opening 4.2 of the second cutting bushing 2.2, the second wire can be cut by the movement of the knife 6.2 in the first direction along the adjustment path relative to the two cutting bushings 2.2; and when the second cutting bushing 2.2 is in the third processing position and the third wire is guided in the third opening 4.2 of the third cutting bushing 2.2, the second wire can be cut by the movement of the other knife 6.2.2 in the first direction along the adjustment path relative to the two cutting bushes 2.2 the third wire can be cut, after which the other knife 6.2 can be moved back in the second direction along the adjustment path relative to the two cutting bushes 2.1, 2.2 driven by the drive 7, in order to then be moved again in the first direction along the adjustment path to cut the first wire 50 or the second wire or the third wire.

[0077] The in the Figures 1a and 1bThe cutting device 1 shown has a cutting drive coupling arrangement 8, by which the drive 7, the two knives 6.1, 6.2 and the two cutting bushings 2.1, 2.2 are coupled to each other and thus can be coupled to each other, in order to drive the movement of the two knives 6.1, 6.2 relative to the two cutting bushings 2.1, 2.2 with the drive 7 and thereby, or rather by this movement along the adjustment path, in the first processing position of the first cutting bushing 2.1, when the first wire 50 is guided in the first opening 4.1 of the first cutting bushing 2.1, to cut the first wire 50 and in the second processing position of the first cutting bushing 2.1, when the second wire is guided in the second opening 4.1 in the first cutting bushing 2.1, to cut the second wire and in the third processing position of the first Cutting box 2.1, when the third wire is in the third opening 5.1 in the first cutting box 2.1 is guided to cut off the third wire, as well as in the first processing position of the second cutting bushing 2.2, when the first wire 50 is guided in the first opening 4.2 of the second cutting bushing 2.2, to cut off the first wire 50, and in the second processing position of the second cutting bushing 2.2, when the second wire is guided in the second opening 4.2 in the second cutting bushing 2.2, to cut off the second wire, and in the third processing position of the second cutting bushing 2.2, when the third wire is guided in the third opening 5.2 in the second cutting bushing 2.2, to cut off the third wire.

[0078] As in the Figures 1a and 1bAs can be seen, the cutting drive coupling arrangement 8 has a cutting bushing carrier 10 and a knife carrier 11 movable relative to the cutting bushing carrier 10, wherein the two cutting bushings 2.1, 2.2 are arranged on the cutting bushing carrier 10 and the two knives 6.1, 6.2 are attached to the knife carrier 11. The drive 7 is arranged on the knife carrier 11 and coupled to the cutting bushing carrier 10 in order to drive a movement of the knife carrier 11 relative to the cutting bushing carrier 10 with the drive 7 and thus drive the movement of the two knives 6.1, 6.2 relative to the two cutting bushings 2.1, 2.2 with the drive 7 and by means of this movement along the adjustment path, when the first cutting bushing 2.1 is in the first processing position and the first wire 50 is guided in the first opening 3.1 of the first cutting bushing 2.1, to cut the first wire 50 and, when the first cutting bushing 2.1 is in the first processing position, to cut the first wire 50 and, when the first cutting bushing 2.1 is in the first processing position, to cut the first wire 50.1 is in the second processing position and the second wire is guided in the second opening 4.1 of the first cutting bushing 2.1, to cut the second wire; and, if the first cutting bushing 2.1 is in the third processing position and the third wire is guided in the third opening 5.1 of the first cutting bushing 2.1, to cut the third wire; and, if the second cutting bushing 2.2 is in the first processing position and the first wire 50 is guided in the first opening 3.2 of the second cutting bushing 2.2, to cut the first wire 50; and, if the second cutting bushing 2.2 is in the second processing position and the second wire is guided in the second opening 4.2 of the second cutting bushing 2.2, to cut the second wire; and, if the second cutting bushing 2.2 is in the third processing position and the third wire is guided in the third opening 5.2 of the second cutting bushing 2.2 is guided, cut off the third wire.

[0079] The Figures 2a and 2b each show an oblique view of the in the Figures 1a and 1b The cutting device 1 shown is from a different perspective than in the Figures 1a and 1b This means that in the Figures 2a and 2b It is now clearer that the drive 7 is a motor arranged on the knife carrier 11. In the Figure 2a The cutting device 1 is as shown in the Figures 1a and 1b with a housing 12 arranged laterally on the drive 7 on the knife carrier 11. In the Figure 2bThis housing 12 is hidden. This reveals that the drive 7 drives a toothed belt 13, which in turn drives a rotary motion of an axis 14 within the housing 12. This axis 14 is rotatably mounted in the knife carrier 11 and coupled to the cutting bushing carrier 10 to drive the movement of the knife carrier 11 relative to the cutting bushing carrier 10, enabling the cutting device 1 to cut a wire as described above.

[0080] The Figures 3a and 3b each show another view of the in the Figures 1a, 1b , 2a and 2b Cutting device 1 shown. In the Figure 3a is an interior view of the I <opplung der Achse 14 mit dem Schnittbüchsenträger 10 gezeigt. Weiter ist in der Figure 3b A sectional view through the cutting device 1, running along axis 14, is shown.

[0081] This means that in the Figures 3a and 3bIt can be seen that the cutting drive coupling arrangement 8 has an eccentric disc 15 arranged on the axis 14 and a driver 16. The eccentric disc 15 is rotatable about the axis 14 relative to the knife carrier 11 by the drive 7. The eccentric disc 15 is arranged eccentrically to the axis 14 or, in the present embodiment, is formed integrally with the axis 14. At the same time, the eccentric disc 15 is rotatably mounted concentrically to a circular recess in the driver 16. Thus, when the eccentric disc 15 is rotated about the axis 14, the driver 16, due to the eccentric disc 15, guides an I <reisbewegung um die Achse 14 aus. Da die Achse 14 ortsfest am Messerträger 11 drehbar gelagert ist, bleibt die Achse 14 bei einer solchen Drehung um die Achse 14 relativ zum Messerträger 11 ortsfest, während aber der Mitnehmer 16 relativ zum Messerträger 11 eine I<reisbewegung um die Achse 14 ausführt.Since the driver 16 is mounted on the cutting tool holder 10 so as to be displaceable relative to the cutting tool holder 10 in a direction of driver movement, the driver 16 is displaced around the axis 14 in the direction of driver movement relative to the cutting tool holder 10 during this rotational movement. In the . Figure 3a This direction of drive movement is vertically aligned in the representation plane.

[0082] Thus, the eccentric disc 15 is arranged eccentrically on the drive 7 and, due to the axis 14 and the bearing of the axis 14 on the cutter carrier 11, can be rotated eccentrically by the drive 7. Due to the concentrically rotatable bearing of the eccentric disc 15 in the recess of the driver 16, the driver 16 can be moved relative to the cutter carrier 10 in the direction of the driver movement by means of an eccentric rotation driven by the drive 7. Furthermore, the cutter carrier 10 is slidably mounted on the cutter carrier 11 in a cutting direction. This cutting direction corresponds to the orientation of the aforementioned adjustment path and is perpendicular to the direction of the driver movement.Therefore, due to the bearing of the eccentric disc 15 in the recess of the driver 16 and the bearing of the driver 16 on the cutting bushing carrier 10, the knife carrier 11 can be displaced by the drive 7 relative to the cutting bushing carrier 10 in the cutting direction.

[0083] Therefore, the respective wire 50 guided in the first or second cutting bushing 2.1, 2.2 can be cut by the drive 7.

[0084] The Figure 4a shows an oblique view of the two cutting boxes 2.1, 2.2, while the Figure 4b A cross-sectional view through the two section bushings 2.1, 2.2 mounted in the section bushing carrier 10 is shown. This allows, based on the Figures 4a, 4bFigure 1 illustrates that the two cutting bushings 2.1, 2.2 each have a substantially cylindrical basic shape. This cylindrical basic shape is arranged concentrically to a cutting bushing axis 9.1, 9.2 of the respective cutting bushing 2.1, 2.2. The two cutting bushings 2.1, 2.2 are each rotatably mounted on the cutting bushing carrier 10 about their respective cutting bushing axis 9.1, 9.2 from the first machining position to the second machining position and to the third machining position, from the second machining position to the first machining position and to the third machining position, and from the third machining position to the first machining position and to the second machining position. This adjustment of the two cutting bushings 2.1, 2.2 is also driven or can be driven by the drive 7. Thus, the first cutting bushing 2.1, 2.2 is moved by the drive 7.1. The first machining position can be adjusted from the first machining position to the second machining position and to the third machining position, from the second machining position to the first machining position and to the third machining position, and from the third machining position to the first machining position and to the second machining position. Furthermore, the second cutting bushing 2.2 can be adjusted by the drive 7 from the first machining position to the second machining position and to the third machining position, from the second machining position to the first machining position and to the third machining position, and from the third machining position to the first machining position and to the second machining position.

[0085] To enable this adjustment of the two cutting bushings 2.1, 2.2, the cutting device 1 has a cutting bushing coupling arrangement 17, by means of which the drive 7 and the two cutting bushings 2.1, 2.2 can be coupled to each other, so that, when the drive 7 and the two cutting bushings 2.1, 2.2 are coupled to each other by means of the cutting bushing coupling arrangement 17, the drive 7 can be used to adjust the two cutting bushings 2.1, 2.2 as desired from the first machining position to the second machining position or to the third machining position, from the second machining position to the first machining position or to the third machining position, and from the third machining position to the first machining position or to the second machining position. This includes the drive 7 and the two cutting bushings 2.1, 2.2 but can also be decoupled from each other by means of the cutting bushing coupling arrangement 17, whereby, when the drive 7 and the two cutting bushings 2.1, 2.2 are decoupled from each other by means of the cutting bushing coupling arrangement 17, the two cutting bushings 2.1, 2.2 cannot be moved from the first machining position to the second machining position or to the third machining position with the drive 7, nor can they each be moved from the second machining position to the first machining position or to the third machining position, nor can they be moved from the third machining position to the first machining position or to the second machining position.

[0086] To couple and decouple the drive 7 and the two cutting bushings 2.1, 2.2, the cutting bushing coupling arrangement 17 has an I <opplungselement 18 und einen Antriebsmotor 19 auf. Das I<opplungselement 18 ist in den Figures 2a and 2b as well as in the Figures 4a and 4bshown. In contrast to the Figures 2a, 2b and 4b is I <opplungselement 18 in der Figure 4a however, it is fully evident, thus the functioning of the I <opplungselements 18 anhand der Figure 4a can be explained better. In contrast, the drive motor 19 is only in the Figures 2a and 2b shown.

[0087] Yes I <opplungselement 18 ist sowohl in die Mitnehmerbewegungsrichtung als auch in eine Richtung parallel zu den Schnittbüchsenachsen 9.1, 9.2 verschiebbar am Messerträger 11 gelagert. Das I<opplungselement 18 weist zwei Arme auf, welche parallel zu den Schnittbüchsenachsen 9.1, 9.2 und parallel zur Achse 14 ausgerichtet sind. Diese Arme, die Schnittbüchsenachsen 9.1, 9.2 sowie die Achse 14 sind sowohl senkrecht zur Mitnehmerbewegungsrichtung als auch senkrecht zur Schneidbewegungsrichtung ausgerichtet. Das I<opplungselement 18 ist durch den Antriebsmotor 19 entlang der Schnittbüchsenachsen 9.1, 9.2 von einer I<opplungsstellung in eine Entkopplungsstellung und zurück verschiebbar am Messerträger 11 gelagert. In der I<opplungsstellung greifen die Arme des I<opplungselements 18 in Ausnehmungen in den zwei Schnittbüchsen 2.1, 2.2 ein. Wie in der Figure 4aAs can be seen, the two cutting guides 2.1, 2.2 have, viewed radially from their respective cutting guide axis 9.1, 9.2, a plurality of I arranged concentrically to the respective cutting guide axis 9.1, 9.2. <reis angeordnete Ausnehmungen auf. Wenn sich das I<opplungselement 18 in der I<opplungsstellung befindet, so greift jeweils einer der zwei Arme des I<opplungselements 18 in eine der Ausnehmungen einer anderen der zwei Schnittbüchsen 2.1, 2.2 ein.

[0088] If in the I <opplungsstellung des I<opplungselements 18 durch den Antrieb 7 der Messerträger 11 relativ zum Schnittbüchsenträger 10 in die Schneidbewegungsrichtung verschoben wird, wird auch das I<opplungselement 18 in die Schneidbewegungsrichtung relativ zum Schnittbüchsenträger 10 verschoben, weil das I<opplungselement 18 nicht in die Schneidbewegungsrichtung relativ zum Messerträger 11 verschiebbar am Messerträger 11 gelagert ist. Da die Arme des I<opplungselements 18 in der I<opplungsstellung in die Ausnehmungen der zwei Schnittbüchsen 2.1, 2.2 eingreifen, werden durch diese Bewegung die zwei Schnittbüchsen 2.1, 2.2 um ihre jeweilige Schnittbüchsenachse 9.1, 9.2 relativ zum Schnittbüchsenträger 10 gedreht, während das I<opplungselement 18 relativ zum Messerträger 11 etwas in die Mitnehmerbewegungsrichtung verschoben wird. Dadurch können die zwei Schnittbüchsen 2.1, 2.2. The two cutting guides 2.1 and 2.2 can be moved at will from the first processing position to the second processing position or to the third processing position, from the second processing position to the first processing position or to the third processing position, and from the third processing position to the first processing position or to the second processing position. As soon as the two cutting guides 2.1 and 2.2 are in the desired first processing position, second processing position, and third processing position, the I <opplungselement 18 durch den Antriebsmotor 19 soweit entlang der Schnittbüchsenachsen 9.1, 9.2 relativ zum Messerträger 11 verschoben werden, dass die zwei Arme des I<opplungselements 18 nicht mehr in die Ausnehmungen in den zwei Schnittbüchsen 2.1, 2.2 eingreifen. Damit befindet sich das I<opplungselement 18 in der Entkopplungsstellung.If in this decoupling position of the I <opplungselements 18 durch den Antrieb 7 der Messerträger 11 relativ zum Schnittbüchsenträger 10 verschoben wird, wird zwar das I<opplungselement 18 zusammen mit dem Messerträger 11 relativ zum Schnittbüchsenträger 10 verschoben. Da die Arme des I<opplungselements 18 in der Entkopplungsstellung aber nicht in die Ausnehmungen der zwei Schnittbüchsen 2.1, 2.2 eingreifen, werden durch diese Bewegung die zwei Schnittbüchsen 2.1, 2.2 nicht um ihre jeweilige Schnittbüchsenachse 9.1, 9.2 relativ zum Schnittbüchsenträger 10 gedreht. Somit kann in dieser Entkopplungsstellung des I<opplungselements 18 mit der Schneidvorrichtung 1 der erste, zweite oder dritte Draht (50) wie vorgehend detailliert beschrieben abgeschnitten werden.

[0089] To hold the two cutting bushings 2.1, 2.2 in their respective first, second, and third machining positions, the cutting device 1 has a detent arrangement 20. This detent arrangement comprises detent notches 21 located on the outer surface of the two cutting bushings 2.1, 2.2, and two detent balls 22.1, 22.2, each of which is spring-loaded and mounted in the cutting bushing carrier 10. When the first cutting bushing 2.1 is in its first, second, or third machining position, one of the two detent balls 22.1 is engaged in a corresponding detent notch in the first cutting bushing 2.1. When the second cutting bushing 2.2 is in its first, second, or third machining position, one of the two detent balls 22.2 is engaged in a corresponding detent notch in the second cutting bushing 2.2. Thus, the cutting device 1 includes a locking arrangement 20 to hold the two cutting bushings 2.1, 2.2 each to lock into the first machining position and thereby hold in the first machining position, in order to lock the two cutting bushings 2.1, 2.2 each into the second machining position and thereby hold in the second machining position, as well as to lock the two cutting bushings 2.1, 2.2 each into the third machining position and thereby hold in the third machining position.

[0090] As explained above and among other places in the Figure 1aAs can be seen, the cutting device 1 in the present embodiment has two blades 6.1, 6.2. Regardless of whether the cutting device also has two cutting guides 2.1, 2.2, only one cutting guide, or even more than two cutting guides, in one variant the cutting device has only one blade. This blade can be dimensioned such that it can cut the wires guided in the one cutting guide or in the two or more cutting guides. Therefore, it is not necessary for the cutting device 1 to have exactly two cutting guides 2.1, 2.2. Thus, the cutting device can have only one cutting guide or more than two cutting guides.Furthermore, it is not necessary for one, two, or more of the potentially multiple existing cutting guides to each have exactly three openings of the respective inner dimension for guiding a wire with a diameter corresponding to the inner dimension. The cutting guides can also have only two such openings each, or more than three. If the cutting guides have only two such openings, it is sufficient if the cutting guides are adjustable only from the first machining position to the second machining position, from the second machining position to the first machining position, or both from the first machining position to the second machining position and from the second machining position to the first machining position.

[0091] The invention is not limited to these embodiments. For example, it is not necessary for the drive to be arranged on the knife carrier. It is also possible for the drive to be arranged on the cutting bushing carrier. In this case, for example, the axis with the eccentric disc can be mounted on the knife carrier so as to be rotatable about the axis, while the driver is mounted on the cutting bushing carrier so as to be movable in the direction of the driver's movement in order to drive the movement of the knife carrier relative to the cutting bushing carrier in order to cut the respective wire. Furthermore, it is not necessary, for example, for this movement to be driven by means of the eccentric disc and the driver. A linear motor can also be used as a drive to move the knife carrier relative to the cutting bushing carrier in order to cut the respective wire.It is also possible that the cutting device does not have a knife carrier, but that the knife is mounted directly so that it can move relative to the cutting bushing carrier.

[0092] In summary, it can be stated that a cutting device belonging to the aforementioned technical field for cutting wire, in particular for cutting cross wires for a welding system, especially a mesh welding system, is created, which is simpler and therefore more cost-effective in design and enables more reliable operation of the cutting device.
