Technical area
[0001] The invention relates to a cutting device for cutting wire, in particular for cutting cross wires for a welding system, in particular a mesh welding system. 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 different from the first internal dimension, wherein the cutting sleeve is adjustable into a first processing position for cutting the first wire, which may be guided in the first opening, and into a second processing position for cutting the second wire, which may be guided in the second opening.The cutting device further comprises a knife for cutting the first wire and the second wire. The knife is movable relative to the cutting sleeve to cut the first wire in the first processing 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 processing position of the cutting sleeve, when the second wire is guided in the second opening in the cutting sleeve. The cutting device also comprises a drive. State of the art
[0002] Cutting devices for cutting wire, which belong to the technical field mentioned above, are known. For example, EP 3 292 933 B1 from Schlatter Industries AG describes such a cutting device. It is a cutting device 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 is different from the first internal dimension.The two cutting bushings can each be adjusted into a first processing position for cutting the first wire, which may be guided in the respective first opening, and into a second processing position for cutting the second wire, which may be guided in the respective second opening. Furthermore, the described cutting device has a knife for cutting the first wire and the second wire, wherein the knife is movable relative to the two cutting bushings in order to cut the first wire in the first processing position of the respective cutting bushing, when the first wire is guided in the first opening of the respective cutting bushing, and in order to cut the second wire in the second processing position of the respective cutting bushing, when the second wire is guided in the second opening in the respective cutting bushing.Furthermore, the cutting device described in EP 3 292 933 B1 has a drive for driving the movement of the knife relative to the two cutting sleeves in order to cut the respective first wire or the respective second wire. Furthermore, the cutting device has a further drive for moving the cutting sleeves from their first processing position to their second processing position and back by means of a worm gear.
[0003] Such known cutting devices have the disadvantage that they are comparatively complex in design and correspondingly expensive to manufacture. Furthermore, due to their complex construction, they are prone to malfunctions and failures. Description of the invention
[0004] The object of the invention is to provide a cutting device belonging to the technical field mentioned at the outset for cutting wire, in particular for cutting cross wires for a welding system, in particular a mesh welding system, which is constructed in a simpler and thus more cost-effective manner 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 different from the first internal dimension. Preferably, the first wire has a first diameter which is slightly smaller than the first internal dimension of the first opening, so that the first wire can be pushed through the first opening essentially without play and can be guided in 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 the second opening with essentially no play and guided within the second opening. Alternatively, the first diameter of the first wire can also be dimensioned differently. Likewise, the second diameter of the second wire can also be dimensioned differently.
[0006] According to the invention, the cutting sleeve is adjustable into a first processing position for cutting the first wire, which may be guided in the first opening, and into a second processing position for cutting the second wire, which may be guided in the second opening. Preferably, the cutting sleeve 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 has a knife for cutting the first wire and the second wire, wherein the knife is movable relative to the cutting sleeve in order to cut the first wire in the first processing position of the cutting sleeve, when the first wire is guided in the first opening of the cutting sleeve, and in order to cut the second wire in the second processing position of the cutting sleeve, when the second wire is guided in the second opening in the cutting sleeve. During operation of the cutting device, both a first wire can be guided in the first opening and a second wire can be guided in the second opening. However, this is not absolutely necessary. Thus, it is possible for only a first wire to be guided in the first opening in order to be cut off, or for only a second wire to be guided in the second opening in order to be cut off.Thus, the cutting device can be designed such that only one first wire can be guided in the first opening or one second wire in the second opening. However, the cutting device can also be designed such that, during operation, both a first wire in the first opening and, at the same time, a second wire in the second opening can be guided. It is therefore important that the knife is suitable for cutting off the first wire, which may be guided in the first opening, when the cutting sleeve is in the first processing position, and is suitable for cutting off the second wire, which may be guided 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. The drive is preferably a motor, in particular an electric motor. However, the drive can also be designed differently.
[0009] Regardless of whether the drive is a motor or not, the drive preferably allows the cutting sleeve to be adjusted both from the first processing position to the second processing position and from the second processing position to the first processing position. However, it is also possible for the drive to only adjust the cutting sleeve from the first processing position to the second processing position, but not from the second processing position to the first processing position. Likewise, it is also possible for the drive to only adjust the cutting sleeve from the second processing position to the first processing position, but not from the first processing position to the second processing position.If the cutting sleeve can only be adjusted from the first processing position to the second processing position by the drive, but not from the second processing position to the first processing position, the cutting sleeve can be adjusted from the second processing position to the first processing position, for example, by a spring return or similar.
[0010] If, however, the drive only allows the cutting sleeve 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, the cutting sleeve can be adjusted from the first machining position to the second machining position, for example, by means of a spring return or similar.
[0011] According to the invention, the drive can also drive the movement of the knife relative to the cutting sleeve in order to cut the first wire by moving the knife relative to the cutting sleeve when the cutting sleeve 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 sleeve when the cutting sleeve is in the second processing position and the second wire is guided in the second opening.
[0012] Both driving the movement of the knife relative to the cutting sleeve in order to cut the first wire by moving the knife relative to the cutting sleeve when the cutting sleeve is in the first processing position and the first wire is guided in the first opening, and cutting the second wire by moving the knife relative to the cutting sleeve when the cutting sleeve is in the second processing position and the second wire is guided in the second opening, as well as driving the adjustment of the cutting sleeve from the first processing position to the second processing position and / or from the second processing position to the first processing position require a drive that can generate a minimum amount of power to successfully drive the movement or adjustment. Such drives that can generate this minimum amount of power reliably without malfunctions or failures are comparatively expensive.By using the same drive both for driving the movement of the knife relative to the cutting sleeve in order to cut the first wire by moving the knife relative to the cutting sleeve when the cutting sleeve 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 sleeve when the cutting sleeve is in the second processing position and the second wire is guided in the second opening, and for driving the adjustment of the cutting sleeve 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 constructed more cost-effectively. At the same time, it also allows for a simpler design. Therefore, the solution according to the invention has the advantage that the cutting device can be constructed 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 feed device for a welding system for welding wire, in particular for a mesh welding system for welding wire to mesh. Accordingly, a wire feed 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] Of course, the cutting device according to the invention can also be manufactured, sold 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 feed 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, sold 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] The cutting device according to the invention is advantageously 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 previously mentioned wire feed device 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 previously mentioned wire feed device with a cutting device according to the invention, the cutting sleeve of the cutting device is in the first processing position or the cutting sleeve of the cutting device is moved into the first processing position by the drive of the cutting device and, when the cutting sleeve is in the first processing position, a first wire to be cut is guided in the first opening of the cutting sleeve.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 blade 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 off 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 off.
[0018] In a preferred variant 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 sleeve 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 sleeve with essentially no play. This has the advantage that the cutting device can be operated very efficiently and reliably.
[0019] Alternatively, the first diameter of the first wire can also be dimensioned differently. Likewise, the second diameter of the second wire can also be dimensioned differently.
[0020] In the cutting device according to the invention, the movement of the knife relative to the cutting sleeve, which can be driven by the drive, in order to cut the first wire by moving the knife relative to the cutting sleeve when the cutting sleeve 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 sleeve when the cutting sleeve is in the second processing position and the second wire is guided in the second opening, is advantageously a movement of the knife along an adjustment path relative to the cutting sleeve, wherein the adjustment path is limited in a first and a second direction.This has the advantage that the movement of the knife relative to the cutting sleeve, which can be driven by the drive, can be designed in an optimally controlled and reliably driven manner in order to cut the first wire by moving the knife relative to the cutting sleeve when the cutting sleeve 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 sleeve when the cutting sleeve is in the second processing position and the second wire is guided in the second opening.
[0021] Preferably, when the cutting sleeve is in the first processing position and the first wire is guided in the first opening, the first wire can be cut off by moving the knife relative to the cutting sleeve in the first direction along the adjustment path, and when the cutting sleeve is in the second processing position and the second wire is guided in the second opening, the second wire can be cut off by moving the knife in the first direction along the adjustment path relative to the cutting sleeve, after which the knife can be moved back in the second direction along the adjustment path relative to the cutting sleeve, in particular can be moved back by the drive, in order to then be moved again in the first direction along the adjustment path to cut off the first wire or the second wire again.This has the advantage that the forces occurring when the knife is moved relative to the cutting sleeve, regardless of the wire to be cut, are greater when moving in the first direction than when moving in the second direction. Accordingly, the cutting device can be designed more simply so that the movement of the knife relative to the cutting sleeve can be driven reliably and robustly. When the cutting sleeve is in the first processing position and the first wire is guided in the first opening, the movement of the knife relative to the cutting sleeve cuts the first wire. When the cutting sleeve is in the second processing position and the second wire is guided in the second opening, the movement of the knife relative to the cutting sleeve cuts the second wire. To achieve this, the drive, for example, can be designed accordingly.Also, if the cutting device has, for example, a cutting drive coupling arrangement as described below, this cutting drive coupling arrangement can be designed accordingly.
[0022] As an alternative to these variants, it is also possible that the movement of the knife relative to the cutting sleeve, which can be driven by the drive, in order to cut off the first wire by moving the knife relative to the cutting sleeve when the cutting sleeve is in the first processing position and the first wire is guided in the first opening, and to cut off the second wire by moving the knife relative to the cutting sleeve when the cutting sleeve 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 sleeve, wherein the adjustment path is limited in a first and a second direction.
[0023] Advantageously, the cutting sleeve is rotatable about a cutting sleeve axis from the first processing position to the second processing position and from the second processing position to the first processing position. Thus, the cutting sleeve can advantageously be adjusted by rotating the cutting sleeve about the cutting sleeve axis both from the first processing position to the second processing position and from the second processing position to the first processing position. The cutting sleeve axis is a geometric axis. However, the cutting sleeve axis can also be a physical axis.
[0024] In a preferred alternative, the cutting sleeve can be moved from the first processing position to the second processing position and from the second processing position to the first processing position. Thus, the cutting sleeve can preferably be adjusted by moving it both from the first processing position to the second processing position and from the second processing position to the first processing position.
[0025] Regardless of whether the cutting sleeve is rotatable about the cutting sleeve axis from the first processing position to the second processing position and from the second processing position to the first processing position and thus adjustable by rotating about the cutting sleeve axis both from the first processing position to the second processing position and from the second processing position to the first processing position, or whether the cutting sleeve is displaceable from the first processing position to the second processing position and from the second processing position to the first processing position and thus adjustable by displacing both from the first processing position to the second processing position and from the second processing position to the first processing position, the cutting device preferably comprises at least one locking arrangement,to lock the cutting sleeve in the first processing position and thereby hold it in the first processing position, as well as to lock the cutting sleeve in the second processing position and thereby hold it in the second processing position. Such a locking arrangement has the advantage that the cutting sleeve can be easily and reliably held in the first processing position as well as in the second processing position. Such a locking arrangement can, for example, be a locking notch arranged on the cutting sleeve and a spring-loaded I arranged on the bearing of the cutting sleeve, for example on the cutting sleeve carrier explained below. <ugel aufweisen, welche Kugel in der Rastkerbe einrasten kann, wenn sich die Schnittbüchse in der ersten Bearbeitungsstellung bzw. in der zweiten Bearbeitungsstellung befindet.,
[0026] Alternatively, however, the cutting device does not comprise a locking arrangement for locking the cutting sleeve in the first machining position and thereby holding it in the first machining position.
[0027] The cutting device advantageously has a cutting drive coupling arrangement, by means of which cutting drive coupling arrangement the drive, the knife and the cutting sleeve can be coupled to one another or are coupled to one another in order to, when the drive, the knife and the cutting sleeve are coupled to one another by the cutting drive coupling arrangement, to drive the movement of the knife relative to the cutting sleeve with the drive and thereby or by means of this movement, in particular along the adjustment path, when the cutting sleeve 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 sleeve is in the second processing position and the second wire is guided in the second opening, to cut the second wire.
[0028] By having this cutting drive coupling arrangement, the cutting device can easily and reliably couple the drive, the knife, and the cutting sleeve to one another in order to drive the movement of the knife relative to the cutting sleeve with the drive and thereby, when the cutting sleeve 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 sleeve is in the second processing position and the second wire is guided in the second opening, to cut the second wire. To achieve this, for example, the drive and the cutting sleeve can be arranged on the same first element, wherein the drive can be used to move the knife relative to this first element.In this example, the cutting drive coupling assembly includes this first member and the connection of the drive to the knife for moving the knife relative to the first member and thus relative to the cutting sleeve. In another example, the drive and the knife are arranged on a same second member, wherein the drive can be used to move the cutting sleeve relative to this second member. In this example, the cutting drive coupling assembly includes this second member and the connection of the drive to the cutting sleeve for moving the cutting sleeve relative to the second member and thus relative to the knife.
[0029] In one variant, the drive, the knife and the cutting sleeve can be coupled to one another by the cutting drive coupling arrangement in order to drive the movement of the knife relative to the cutting sleeve with the drive as described above and thereby cut the first wire or the second wire, and the drive, the knife and the cutting sleeve can be decoupled from one another by the cutting drive coupling arrangement, whereby, when the drive, the knife and the cutting sleeve are decoupled from one another, the movement of the knife relative to the cutting sleeve cannot be driven by the drive in order not to cut the first wire even when the cutting sleeve is in the first processing position and the first wire is guided in the first opening, and not to cut the second wire even when the cutting sleeve is in the second processing position and the second wire is guided in the second opening.This variant has the advantage that the movement of the knife relative to the cutting sleeve can be prevented despite the active drive by decoupling the drive, the knife, and the cutting sleeve using the cutting drive coupling arrangement. This can be advantageous if, for example, the cutting sleeve is to be moved from the first processing position to the second processing position or from the second processing position to the first processing position using the drive, and if the knife is not to be moved relative to the cutting sleeve.
[0030] In a preferred alternative, however, the drive, the knife, and the cutting sleeve cannot be decoupled from one another 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 to be simpler and less error-prone, thus allowing for more reliable operation.
[0031] Preferably, the cutting drive coupling arrangement comprises a cutting bush carrier and a knife carrier which is movable relative to the cutting bush carrier, wherein the cutting bush is arranged on the cutting bush carrier and the knife is arranged on the knife carrier, wherein the drive is arranged on a first carrier of the cutting bush carrier and the knife carrier and is coupled to a second carrier of the cutting bush carrier and the knife carrier in order to drive a movement of the knife carrier relative to the cutting bush carrier with the drive and thus to drive the movement of the knife relative to the cutting bush with the drive and thereby orby means of this movement, in particular along the adjustment path, when the cutting sleeve 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 sleeve is in the second processing position and the second wire is guided in the second opening, to cut the second wire. The wording that the drive is arranged on a first carrier of the cutting sleeve carrier and the knife carrier and is coupled to a second carrier of the cutting sleeve carrier and the knife carrier means that if the cutting sleeve carrier is the first carrier of the cutting sleeve carrier and the knife carrier, the second carrier of the cutting sleeve carrier and the knife carrier is the knife carrier.If, however, the knife carrier is the first carrier of the cutting sleeve carrier and the knife carrier, then the second carrier of the cutting sleeve carrier and the knife carrier is the cutting sleeve carrier.
[0032] By having the cutting drive coupling arrangement as explained above a cutting sleeve carrier and a knife carrier movable relative to the cutting sleeve carrier, the advantage is achieved that the cutting drive coupling arrangement can be constructed robustly in a simple manner.
[0033] Preferably, the cutting sleeve carrier is movably mounted on the knife carrier, or the knife carrier is movably mounted on the cutting sleeve carrier. In a first variant, the cutting sleeve carrier is slidably mounted on the knife carrier, or the knife carrier is slidably mounted on the cutting sleeve carrier. In a second variant, however, the cutting sleeve carrier is pivotably mounted on the knife carrier, or the knife carrier is pivotably mounted on the cutting sleeve carrier. This has the advantage that the cutting device can be constructed compactly. As an alternative to these variants, neither the cutting sleeve carrier is movably mounted on the knife carrier, nor is the knife carrier movably mounted on the cutting sleeve carrier. Thus, one or both of the cutting sleeve carrier and the knife carrier can be movably, in particular displaceably or pivotably mounted, on another element of the cutting device.
[0034] Preferably, the knife is fixedly mounted on the knife carrier. This has the advantage that the cutting device can be constructed very robustly and that the movement of the knife relative to the cutting sleeve can be easily and reliably guided by movably mounting the knife carrier on another element of the cutting device, such as the cutting sleeve carrier. In a variant of this, however, the knife is movably mounted on the knife carrier.
[0035] Regardless of whether the cutting sleeve carrier is movably mounted on the knife carrier, whether the knife carrier is movably mounted on the cutting sleeve carrier, or whether one or both of the cutting sleeve carrier and the knife carrier are movably mounted on another element of the cutting device, the cutting sleeve is advantageously mounted on the cutting sleeve carrier so that it can be adjusted from the first processing position to the second processing position and from the second processing position to the first processing position relative to the cutting sleeve carrier. This has the advantage that the cutting sleeve can be held stably in the first processing position and in the second processing position in a simple manner and can still be designed to be adjustable from the first processing position to the second processing position and from the second processing position to the first processing position.
[0036] In a first preferred variant, the cutting sleeve is mounted on the cutting sleeve carrier so that it can rotate about the cutting sleeve axis from the first processing position to the second processing position and from the second processing position to the first processing position. This means that in this first preferred variant, the cutting sleeve can be adjusted by rotating about the cutting sleeve axis both from the first processing position to the second processing position and from the second processing position to the first processing position. The cutting sleeve axis is a geometric axis. The cutting sleeve axis can also be a physical axis. In a second preferred variant, however, the cutting sleeve is mounted on the cutting sleeve carrier so that it can be moved from the first processing position to the second processing position and from the second processing position to the first processing position. This means thatIn this second preferred variant, the cutting bushing is adjustable by moving it from the first processing position to the second processing position as well as from the second processing position to the first processing position.
[0037] Regardless of whether or not the cutting bush is adjustably mounted on the cutting bush carrier from the first processing position to the second processing position and from the second processing position to the first processing position, the cutting drive coupling arrangement preferably comprises an eccentric disc and a driver. The eccentric disc is preferably rotatably mounted concentrically in a recess in the driver. This means that when the eccentric disc is rotated in the recess of the driver, a center of rotation of the eccentric disc remains unchanged at the same position relative to the recess of the driver due to the concentric mounting. Furthermore, the driver is preferably mounted on the second carrier of the cutting bush carrier and the knife carrier so that it can be moved, in particular displaced, in a driver movement direction relative to the second carrier of the cutting bush carrier and the knife carrier.In addition, the eccentric disc is preferably arranged eccentrically on the drive and can therefore be rotated 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 carrier of the cutting sleeve carrier and the knife carrier in the driver movement direction due to the drive-driven eccentric rotation of the eccentric disc. In addition, due to the mounting of the driver on the second carrier of the cutting sleeve carrier and the knife carrier, the knife carrier can be moved, in particular displaced, relative to the cutting sleeve carrier in a cutting movement direction in order to drive the movement of the knife relative to the cutting sleeve in the cutting movement direction using the drive and thereby orby means of this movement, in particular along the adjustment path, when the cutting sleeve 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 sleeve is in the second processing position and the second wire is guided in the second opening, to cut the second wire. With this arrangement, the drive is arranged on the first carrier of the cutting sleeve carrier and the knife carrier and is coupled by the eccentric slide and the driver to the second carrier of the cutting sleeve carrier and the knife carrier in order to drive the movement of the knife relative to the cutting sleeve with the drive and thereby orby means of this movement, in particular along the adjustment path, when the cutting sleeve 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 sleeve 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 movement direction is oriented substantially perpendicular to the driver movement direction. In a variant, however, the cutting movement direction is not oriented substantially perpendicular to the driver movement direction.
[0039] As an alternative to these variants, it is also possible for the cutting drive coupling arrangement not to include such an eccentric disc and such a driver.
[0040] Preferably, the cutting device has a cutting sleeve coupling arrangement, by means of which cutting sleeve coupling arrangement the drive and the cutting sleeve can be coupled to one another in order to, when the drive and the cutting sleeve are coupled to one another by the cutting sleeve coupling arrangement, to adjust the cutting sleeve with the drive from the first processing position to the second processing position, to adjust it from the second processing position to the first processing position, or to adjust it both from the first processing position to the second processing position and from the second processing position to the first processing position.Preferably, the drive and the cutting sleeve can be decoupled from one another by the cutting sleeve coupling arrangement, whereby, when the drive and the cutting sleeve are decoupled from one another by the cutting sleeve coupling arrangement, the cutting sleeve cannot be adjusted from the first processing position to the second processing position or from the second processing position to the first processing position using the drive.
[0041] This has the advantage that, when the drive and the cutting sleeve are decoupled from one another by the cutting sleeve coupling arrangement, the knife can be moved relative to the cutting sleeve with the drive in order to cut the first wire in the first processing 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 processing position of the cutting sleeve, when the second wire is guided in the second opening in the cutting sleeve, without the cutting sleeve being moved from the first processing position to the second processing position or from the second processing position to the first processing position at the same time.
[0042] Advantageously, the cutting device comprises both the cutting drive coupling arrangement and the cutting sleeve coupling arrangement. The drive, the knife, and the cutting sleeve are preferably coupled to one another by the cutting drive coupling arrangement in order to drive the movement of the knife relative to the cutting sleeve with the drive and thereby or by this movement, in particular along the adjustment path, when the cutting sleeve 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 sleeve 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 sleeve are preferably coupled to one another by the cutting sleeve coupling arrangement in order to, when the drive and the cutting sleeve are coupled to one another by the cutting sleeve coupling arrangement, to adjust the cutting sleeve with the drive from the first processing position to the second processing position, to adjust it from the second processing position to the first processing position, or to adjust it both from the first processing position to the second processing position and from the second processing position to the first processing position.Furthermore, the drive and the cutting sleeve can preferably be decoupled from one another by the cutting sleeve coupling arrangement, whereby, when the drive and the cutting sleeve are decoupled from one another by the cutting sleeve coupling arrangement, the cutting sleeve cannot be adjusted with the drive from the first processing position to the second processing position and not from the second processing position to the first processing position.Since in this variant the drive, the knife, and the cutting sleeve are coupled to one another by the cutting drive coupling arrangement, the movement of the knife relative to the cutting sleeve is preferably always driven by the drive in order to cut the first wire when the cutting sleeve 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 sleeve is in the second processing position and the second wire is guided in the second opening. In contrast, the cutting sleeve coupling arrangement allows the adjustment of the cutting sleeve from the first processing position to the second processing position or from the second processing position to the first processing position to be switched on by coupling the drive to the cutting sleeve or switched off by decoupling the drive from the cutting sleeve.This enables simple operation of the cutting device. At the same time, it also makes it possible to design the cutting device in a simple manner for particularly reliable operation. For example, greater forces act on the cutting device during the cutting process of the first wire or second wire than when adjusting the cutting sleeve from the first processing position to the second processing position or from the second processing position to the first processing position. By coupling the drive, the knife, and the cutting sleeve with one another via the cutting drive coupling arrangement, the cutting drive coupling arrangement can be easily constructed to be very reliable and robust. When adjusting the cutting sleeve, however, lower forces act on the cutting device. This means that a less robust cutting sleeve coupling arrangement is sufficient.A less robust cutting sleeve coupling arrangement is easier to design in such a way that it can couple the drive to and decouple it from the cutting sleeve. Therefore, the cutting device designed in this way can be designed for particularly reliable operation in a simple manner.
[0043] In an advantageous variant, the drive, the knife, and the cutting sleeve are coupled to one another by the cutting drive coupling arrangement in order to drive the movement of the knife relative to the cutting sleeve with the drive and thereby or through this movement, when the cutting sleeve 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 sleeve is in the second processing position and the second wire is guided in the second opening, to cut the second wire. Furthermore, the knife and the cutting sleeve are preferably coupled to one another by the cutting sleeve coupling arrangement in order to, when the knife and the cutting sleeve are coupled to one another by the cutting sleeve coupling arrangement, to move the cutting sleeve from the first processing position to the second processing position by the movement of the knife relative to the cutting sleeve.from the second processing position to the first processing position or from the first processing position to the second processing position as well as from the second processing position to the first processing position, wherein the drive and the cutting sleeve can be decoupled from one another by the cutting sleeve coupling arrangement, whereby, when the knife and the cutting sleeve are decoupled from one another by the cutting sleeve coupling arrangement, the cutting sleeve cannot be adjusted from the first processing position to the second processing position or from the second processing position to the first processing position by the movement of the knife relative to the cutting sleeve. In this variant, the drive, the knife and the cutting sleeve are coupled to one another by the cutting drive coupling arrangement,in order to drive the movement of the knife relative to the cutting sleeve with the drive and thereby or by this movement, in particular along the adjustment path, when the cutting sleeve 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 sleeve is in the second processing position and the second wire is guided in the second opening, to cut the second wire, the drive and the cutting sleeve can also be coupled to one another by the cutting sleeve coupling arrangement, in order to adjust the cutting sleeve from the first processing position to the second processing position with the drive, from the second processing position to the first processing position,or to be adjusted both from the first processing position to the second processing position and from the second processing position to the first processing position, and the drive and the cutting sleeve can be decoupled from one another by the cutting sleeve coupling arrangement, whereby, since the knife and the cutting sleeve are decoupled from one another by the cutting sleeve coupling arrangement, the movement of the knife relative to the cutting sleeve does not adjust the cutting sleeve from the first processing position to the second processing position, nor from the second processing position to the first processing position. This has the advantage that the cutting device can be constructed particularly simply.
[0044] Advantageously, the cutting sleeve coupling arrangement has 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 adjust 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, wherein both cutting bushings each have a first opening for guiding a first wire to be cut off and a second opening for guiding a second wire to be cut off, wherein the first opening in each case has a first internal dimension and the second opening in each case has a second internal dimension different from the first internal dimension, wherein the cutting bushings are adjustable into a first processing position for cutting the first wire, which may be guided in the first opening, and into a second processing position for cutting the second wire, which may be guided in the second opening, wherein the knife is movable relative to the two cutting bushings in order to cut the first wire in a first of the two cutting bushings 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, and,in the second processing position of the first cutting sleeve, when the second wire is guided in the second opening in the first cutting sleeve, to cut the second wire, and in a second of the two cutting sleeves, in the first processing position of the second cutting sleeve, when the first wire is guided in the first opening of the second cutting sleeve, to cut the first wire and, in the second processing position of the second cutting sleeve, when the second wire is guided in the second opening in the second cutting sleeve, to cut the second wire, wherein the drive moves the first cutting sleeve from the first processing position into the second processing position,from the second processing position to the first processing position or both from the first processing position to the second processing position and from the second processing position to the first processing position, and the drive enables the second cutting sleeve to be moved from the first processing position to the second processing position, from the second processing position to the first processing position, or both from the first processing position to the second processing position and from the second processing position to the first processing position. This allows, depending on the current processing position of the cutting sleeves and whether a wire to be cut is guided in the corresponding opening of the respective cutting sleeve in only one or both cutting sleeves,that with a single movement of the knife relative to the two cutting bushes, only the first wire guided in the first opening of the first cutting bush, only the second wire guided in the second opening of the first cutting bush, only the first wire guided in the first opening of the second cutting bush, only the second wire guided in the second opening of the second cutting bush, the first wire guided in the first opening of the first cutting bush and the first wire guided in the first opening of the second cutting bush, the first wire guided in the first opening of the first cutting bush and the second wire guided in the second opening of the second cutting bush,the second wire guided in the second opening of the first cutting sleeve as well as the first wire guided in the first opening of the second cutting sleeve or the second wire guided in the second opening of the first cutting sleeve as well as the second wire guided in the second opening of the second cutting sleeve can be cut off.

Since, in this particularly preferred variant, the two cutting bushings are both in the first processing position or in the second processing position, in this particularly preferred variant, only six of the eight wire cutting variants explained 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 bushes and depending on whether a wire to be cut is guided in the corresponding opening of the respective cutting bush in only one or both cutting bushes or not, in a single movement of the knife relative to the two cutting bushes, only the first wire guided in the first opening of the first cutting bush, only the second wire guided in the second opening of the first cutting bush, only the first wire guided in the first opening of the second cutting bush, only the second wire guided in the second opening of the second cutting bush, the first wire guided in the first opening of the first cutting bush and the first wire guided in the first opening of the second cutting bush, or the second wire guided in the second opening of the first cutting bush and the second wire guided in the second opening of the second cutting bush can be cut.

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

[0069] In principle, identical parts in the figures are provided with identical reference symbols. Ways to implement the invention
[0070] The Figures 1a and 1b Each shows an oblique view of a cutting device 1 according to the invention for cutting wire 50. More specifically, this is a cutting device 1 for cutting cross wires for a mesh welding system. This cutting device 1 can thus be used in a welding system and also in a mesh welding system.
[0071] The cutting device 1 has two cutting bushings 2.1, 2.2, wherein each of the cutting bushings 2.1, 2.2 has 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. In this case, the first opening 3.1, 3.2 has a first internal dimension, while the second opening 4.1, 4.2 has a second internal dimension different from the first internal dimension, and the third opening has a third internal dimension different from the first internal dimension and the second internal dimension. These cutting bushings 2.1, 2.2 and the openings 3.1, 3.2, 4.1, 4.2, 5.1, 5.2 are shown in the Figure 4a The two cutting boxes 2.1, 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, 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 bushes 2.1, 2.2 in order to cut the first wire 50 in a first of the two cutting bushes 2.1, in the first processing position of the first cutting bush 2.1, when the first wire 50 is guided in the first opening 3.1 of the first cutting bush 3.1, and to cut the second wire in the second processing position of the first cutting bush 2.1, when the second wire is guided in the second opening 4.1 in the first cutting bush 2.1, and to cut the third wire in the third processing position of the first cutting bush 2.1, when the third wire is guided in the third opening 5.1 in the first cutting bush 2.1, and to cut the third wire in a second of the two cutting bushes 2.2, in the first processing position of the second cutting bush 2.2, when the first wire 50 is in the first opening 3.2 of the second cutting sleeve 2.2 is guided, to cut the first wire 50 and in the second processing position of the second cutting sleeve 2.2, when the second wire is guided in the second opening 4.2 in the second cutting sleeve 2.2, to cut the second wire, and in the third processing position of the second cutting sleeve 2.2, when the third wire is guided in the third opening 4.2 in the second cutting sleeve 2.2, to cut the third wire.

Thus, in the Figure 1a The first wire 50 guided in the first opening 3.1 of the first cutting sleeve 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 sleeve 2.1 and thus next to the first wire 50 guided in the first opening 3.1 of the first cutting sleeve 2.1. Figure 1bhowever, the knife 6.1 is moved relative to the first cutting sleeve 2.1 in front of the first opening 3.1 of the first cutting sleeve 2.1, whereby the first wire 50 is cut off.
[0074] The cutting device 1 also has a drive 7. This drive 7 drives the movement of the two knives 6.1, 6.2 relative to the two cutting bushings 2.1, 2.2 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.

[0076] 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, the first wire 50 can be cut off by moving one knife 6.1 relative to the two cutting bushings 2.1, 2.2 in the first direction along the adjustment path, and 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 of the first cutting bushing 2.1, the second wire can be cut off by moving one knife 6.1 in the first direction along the adjustment path relative to the two cutting bushings 2.1, 2.2, and 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 of the first cutting bushing 2.1, the first wire 50 can be cut off by moving one knife 6.1 in the first direction along the adjustment path. Adjustment range relative to the two cutting bushes 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 off 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. 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 off by the movement of the knife 6.2 in the first direction along the adjustment path relative to the two cutting bushings 2.2.

[0077] The Figures 1a and 1bThe cutting device 1 shown has a cutting drive coupling arrangement 8, by means of which cutting drive coupling arrangement 8 the drive 7, the two knives 6.1, 6.2 and the two cutting bushes 2.1, 2.2 are coupled to one another and can thus be coupled to one another in order to drive the movement of the two knives 6.1, 6.2 relative to the two cutting bushes 2.1, 2.2 with the drive 7 and thereby or by means of this movement along the adjustment path in the first processing position of the first cutting bush 2.1, when the first wire 50 is guided in the first opening 4.1 of the first cutting bush 2.1, to cut the first wire 50 and in the second processing position of the first cutting bush 2.1, when the second wire is guided in the second opening 4.1 in the first cutting bush 2.1, to cut the second wire and in the third processing position of the first Cutting box 2.1, when the third wire in the third opening 5.1 in the first cutting box 2.1 is guided, to cut off the third wire, and in the first processing position of the second cutting sleeve 2.2, when the first wire 50 is guided in the first opening 4.2 of the second cutting sleeve 2.2, to cut off the first wire 50 and in the second processing position of the second cutting sleeve 2.2, when the second wire is guided in the second opening 4.2 in the second cutting sleeve 2.2, to cut off the second wire and in the third processing position of the second cutting sleeve 2.2, when the third wire is guided in the third opening 5.2 in the second cutting sleeve 2.2, to cut off the third wire.
[0078] As in the Figures 1a and 1b As can be seen, the cutting drive coupling arrangement 8 has a cutting sleeve carrier 10 and a knife carrier movable relative to the cutting sleeve carrier 10 11 , whereby the two cutting bushes 2.1, 2.2 are arranged on the cutting bush carrier 10 and on the knife carrier 11the two knives 6.1, 6.2 are attached. The drive 7 is on the knife carrier 11 arranged and coupled to the cutting sleeve carrier 10 to prevent movement of the knife carrier 11to drive the cutting bushing carrier 10 with the drive 7 and thus 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 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 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, 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 of the first cutting bushing 2.1, 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 of the second cutting sleeve 2.2, to cut the first wire 50 and, when the second cutting sleeve 2.2 is in the second processing position and the second wire is guided in the second opening 4.2 of the second cutting sleeve 2.2, to cut the second wire and, when the second cutting sleeve 2.2 is in the third processing position and the third wire is guided in the third opening 5.2 of the second cutting sleeve 2.2, to cut the third wire.
[0079] The Figures 2a and 2b each show an oblique view of the Figures 1a and 1b shown cutting device 1 from a different perspective than in the Figures 1a and 1b . This means that in the Figures 2a and 2b It can be seen more clearly 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 1bwith a housing 12 arranged laterally on the blade carrier 11, the drive 7. In the Figure 2b This housing 12 is hidden. It can be seen that the drive 7 drives a toothed belt 13, which drives a rotary movement of an axis 14 within the housing 12. This axis 14 is rotatably mounted in the knife carrier 11 and coupled to the cutting sleeve carrier 10 in order to drive the movement of the knife carrier 11 relative to the cutting sleeve carrier 10 in order to be able to cut a wire with the cutting device 1 as described above.
[0080] The Figures 3a and 3b each show another view of the Figures 1a, 1b , 2a and 2b shown cutting device 1. In the Figure 3a is an internal view of the coupling of the axis 14 with the cutting sleeve carrier 10. Furthermore, the Figure 3b a sectional view through the cutting device 1 running along the 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 on 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 in a circular recess of the driver 16 concentrically to the recess. When the eccentric disc 15 is thus rotated about the axis 14, the driver 16 performs a <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 bushing carrier 10 so as to be displaceable in a driver movement direction relative to the cutting bushing carrier 10, the driver 16 is displaced in the driver movement direction relative to the cutting bushing carrier 10 during this rotational movement about the axis 14. In the . Figure 3a this driver movement direction is aligned vertically in the display 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 blade carrier 11, is eccentrically rotatable 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 cutting sleeve carrier 10 in the driver movement direction by an eccentric rotation of the eccentric disc 15 driven by the drive 7. Furthermore, the cutting sleeve carrier 10 is mounted on the blade carrier 11 so that it can be displaced in a cutting movement direction. This cutting movement direction corresponds to the orientation of the previously mentioned adjustment path and is oriented perpendicular to the driver movement direction.Therefore, due to the mounting of the eccentric disc 15 in the recess of the driver 16 and the mounting of the driver 16 on the cutting sleeve carrier 10, the knife carrier 11 can be displaced by the drive 7 relative to the cutting sleeve carrier 10 in the cutting movement direction.
[0083] Therefore, the respective wire 50 guided in the first or second cutting sleeve 2.1, 2.2 can be cut off 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 cutting bushes 2.1, 2.2 mounted in the cutting bush carrier 10. This allows Figures 4a, 4billustrates that the two cutting bushes 2.1, 2.2 each have a substantially cylindrical basic shape. This cylindrical basic shape is arranged concentrically to a cutting bush axis 9.1, 9.2 of the respective cutting bush 2.1, 2.2. The two cutting bushes 2.1, 2.2 are each rotatably mounted on the cutting bush carrier 10 about their respective cutting bush axis 9.1, 9.2 from the first processing position to the second processing position and into the third processing position, from the second processing position to the first processing position and into the third processing position, and from the third processing position to the first processing position and into the second processing position. This adjustment of the two cutting bushes 2.1, 2.2 is also driven or drivable by the drive 7. Thus, the first cutting bush 2 is driven by the drive 7.1 can be adjusted from the first processing position to the second processing position and into the third processing position, from the second processing position to the first processing position and into the third processing position, and from the third processing position to the first processing position and into the second processing position. Furthermore, the drive 7 can adjust the second cutting sleeve 2.2 from the first processing position to the second processing position and into the third processing position, from the second processing position to the first processing position and into the third processing position, and from the third processing position to the first processing position and into the second processing position.
[0085] In order to enable this adjustment of the two cutting bushes 2.1, 2.2, the cutting device 1 has a cutting bush coupling arrangement 17, by means of which cutting bush coupling arrangement 17 the drive 7 and the two cutting bushes 2.1, 2.2 can be coupled to one another in order to, when the drive 7 and the two cutting bushes 2.1, 2.2 are coupled to one another by the cutting bush coupling arrangement 17, use the drive 7 to adjust the two cutting bushes 2.1, 2.2 as desired from the first processing position to the second processing position or to the third processing position, to adjust each from the second processing position to the first processing position or to the third processing position and to adjust from the third processing position to the first processing position or to the second processing position. The drive 7 and the two cutting bushes 2.1, 2.2 but can also be decoupled from one another by the cutting sleeve coupling arrangement 17, whereby, when the drive 7 and the two cutting sleeves 2.1, 2.2 are decoupled from one another by the cutting sleeve coupling arrangement 17, the two cutting sleeves 2.1, 2.2 cannot be adjusted from the first processing position to the second processing position or to the third processing position with the drive 7, cannot be adjusted from the second processing position to the first processing position or to the third processing position and cannot be adjusted from the third processing position to the first processing position or to the second processing position.
[0086] In order to couple the drive 7 and the two cutting bushes 2.1, 2.2 with each other and to decouple them from each other, the cutting bush 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 4bIn contrast to the Figures 2a, 2b and 4b is the I <opplungselement 18 in der Figure 4a However, it is completely clear how the I <opplungselements 18 anhand der Figure 4a can be better explained. 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 bushes 2.1, 2.2 have, viewed from their respective cutting bush axes 9.1, 9.2, a plurality of recesses arranged on a circle concentrically arranged to the respective cutting bush axes 9.1, 9.2, radially outside their respective first, second and third openings 3.1, 3.2, 4.1, 4.2, 5.1, 5.2. When the 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 can be adjusted as desired 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 bushes 2.1, 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] In order to hold the two cutting bushings 2.1, 2.2 in the desired first processing position, second processing position, and third processing position, the cutting device 1 has a locking arrangement 20. This locking arrangement comprises locking notches 21 arranged on the casing side in the two cutting bushings 2.1, 2.2, as well as two locking 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 processing position, a first of the two locking balls 22.1 is engaged in a corresponding locking notch in the first cutting bushing 2.1. When the second cutting bushing 2.2 is in its first, second, or third processing position, a second of the two locking balls 22.2 is engaged in a corresponding locking notch in the second cutting bushing 2.2. Thus, the cutting device 1 comprises a locking arrangement 20 to lock the two cutting bushes 2.1, 2.2 each in the first processing position and thereby hold them in the first processing position, to lock the two cutting bushes 2.1, 2.2 each in the second processing position and thereby hold them in the second processing position, as well as to lock the two cutting bushes 2.1, 2.2 each in the third processing position and thereby hold them in the third processing position.
[0090] As explained above and, among other things, in the Figure 1aAs can be seen, the cutting device 1 in the present exemplary embodiment has two knives 6.1, 6.2. Regardless of whether the cutting device also has two cutting bushings 2.1, 2.2 or only one cutting bushing or even more than two cutting bushings, in one variant the cutting device has only one knife. The knife can be dimensioned such that this one knife can be used to cut the wires guided in one cutting bushing or in two or more cutting bushings. Furthermore, it is therefore not necessary for the cutting device 1 to have exactly two cutting bushings 2.1, 2.2. The cutting device can therefore also have only one cutting bushing or more than two cutting bushings.Furthermore, it is not necessary for one, two, or more of the possibly several cutting bushings each to have exactly three openings of the respective internal dimension for guiding a wire with a diameter corresponding to the internal dimension. Thus, the cutting bushings can each have only two such openings or more than three such openings. If the cutting bushings have only two such openings, it is sufficient if the cutting bushings can be adjusted only from the first processing position to the second processing position, from the second processing position to the first processing position, or both from the first processing position to the second processing position and from the second processing position to the first processing 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 sleeve carrier. In this case, for example, the axis with the eccentric disc on the knife carrier can be mounted in a fixed position so as to rotate about the axis, while the driver on the cutting sleeve carrier is mounted so as to be movable in the driver movement direction in order to drive the movement of the knife carrier relative to the cutting sleeve carrier in order to cut the respective wire. Furthermore, it is also not necessary, for example, for this movement to be driven by the eccentric disc and the driver. For example, a linear motor can also be used as a drive to move the knife carrier relative to the cutting sleeve carrier in order to cut the respective wire.It is also possible that the cutting device does not have a knife holder, but that the knife is mounted so that it can move relative to the cutting sleeve holder.
[0092] In summary, it can be stated that a cutting device belonging to the technical field mentioned at the outset for cutting wire, in particular for cutting cross wires for a welding system, in particular a mesh welding system, is created, which is of simpler and thus more cost-effective construction and enables more reliable operation of the cutting device.
