The cutting device also comprises a drive.

State of the art

Cutting devices for cutting wire, which belong to the technical field mentioned above, are known. For example, the EP 3 292 933 B1 Schlatter Industries AG has developed such a cutting device. It is a cutting device for cutting cross wires for a mesh welding system. The The cutting device described has two cutting bushes. Each cutting bush 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 of the cutting bushes, 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 bushes can each be adjusted to a first processing position for cutting the first wire, which may be guided in the respective first opening, and to 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 sleeves in order to cut the first wire in the first processing position of the respective cutting sleeve, when the first wire is guided in the first opening of the respective cutting sleeve, and in order to cut the second wire in the second processing position of the respective cutting sleeve, when the second wire is guided in the second opening in the respective cutting sleeve. Furthermore, the EP 3 292 933 B1 The cutting device described 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. In addition, the cutting device has a further drive for adjusting the cutting sleeves from their first processing position to their second processing position and back by means of a worm gear.

Such known cutting devices have the disadvantage that they are comparatively complex to construct and are correspondingly expensive to manufacture. In addition, due to the complex construction, they are susceptible to malfunctions and failures.

representation of the invention

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 simpler and therefore more cost-effective and enables more reliable operation of the cutting device.

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, the first opening having a first internal dimension and the second opening having a second internal dimension that is different 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 can be guided in the first opening. In addition, the second wire preferably has a second diameter that is slightly smaller than the second internal dimension of the second opening, so that the second wire can be pushed through the second opening with essentially no play and can be guided in 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.

According to the invention, the cutting sleeve can be adjusted 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. The cutting sleeve can preferably be adjusted from the first processing position to the second processing position and from the second processing position to the first processing position.

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 in the first opening and a second Wire can be guided in the second opening. However, this is not absolutely necessary. For example, it is possible that, during operation of the cutting device, only a first wire is guided in the first opening to be cut off, or that only a second wire is guided in the second opening to be cut off. The cutting device can therefore be designed such that only either a first wire can be guided in the first opening or a second wire in the second opening. The cutting device can also be designed such that, during operation, both a first wire in the first opening and a second wire in the second opening can be guided at the same time. 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.

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.

Regardless of whether the drive is a motor or not, the drive preferably enables the cutting bushing 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 bushing from the first processing position to the second processing position and not from the second processing position to the first processing position. Likewise, it is also possible for the drive to only adjust the cutting bushing from the second processing position to the first processing position and not from the first processing position to the second processing position. If the drive only enables the cutting bushing to be adjusted from the first processing position to the second processing position and not from the second processing position to the first processing position, the cutting bushing can be adjusted from the second processing position to the first processing position, for example, by a spring return or something similar.

If, however, the drive only allows the cutting sleeve to be adjusted from the second processing position to the first processing position, but not from the first processing position to the second processing position, the cutting sleeve can be adjusted from the first processing position to the second processing position, for example, by means of a spring return or similar.

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.

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 provide a minimum amount of power to successfully drive the movement or adjustment. Such drives that can provide this minimum amount of power reliably without malfunctions or failures are comparatively expensive. By both driving the movement of the knife relative to the cutting sleeve in order to cut the first wire by the movement of 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, 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 in order to cut the second wire to cut, 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, this also enables the cutting device to be constructed more simply. The solution according to the invention therefore has the advantage that the cutting device can be constructed more simply and thus more cost-effectively and that at the same time a more reliable operation of the cutting device can be enabled.

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.

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.

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 mentioned above with a cutting device according to the invention.

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

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 sleeve of the cutting device is in the first processing position or the cutting sleeve of the cutting device is adjusted to 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 adjusted to 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 with the drive of the cutting device relative to the cutting sleeve 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.

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 essentially without 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 essentially without play. This has the advantage that the cutting device can be operated very efficiently and reliably.

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.

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, 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, can be designed to be driven in an optimally controlled and reliable manner.

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, it can be moved back driven by the drive, in order to then be moved again in the first direction along the adjustment path in order to cut 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 in such a way that the movement of the knife relative to the cutting sleeve can be driven reliably and robustly 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. In order to achieve this, the drive can, for example, 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.

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 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 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.

Advantageously, the cutting bush can be rotated about a cutting bush axis from the first processing position to the second processing position and from the second processing position to the first processing position. Advantageously, the The cutting sleeve can be adjusted by rotating the cutting sleeve around 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. The cutting sleeve axis is a geometric axis. The cutting sleeve axis can also be a physical axis.

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. The cutting sleeve can therefore 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.

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 latching arrangement for latching the cutting sleeve in the first processing position and thereby holding it in the first processing position and for latching the cutting sleeve in the second processing position and thereby holding it in the second processing position. Such a locking arrangement has the advantage that the cutting bush can be held reliably in the first processing position and in the second processing position in a simple manner. Such a locking arrangement can, for example, have a locking notch arranged on the cutting bush and a spring-loaded eye arranged on the bearing of the cutting bush, for example on the cutting bush carrier explained below. which eye can engage in the locking notch when the cutting sleeve is in the first machining position or in the second machining position.

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.

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 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.

By having the cutting device with this cutting drive coupling arrangement, the drive, the knife and the cutting sleeve can be coupled to one another in a simple and reliable manner in order to use the drive to drive the movement of the knife relative to the cutting sleeve 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 a 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 arrangement comprises this first element and the connection of the drive to the knife in order to move the knife relative to the first element and thus relative to the cutting sleeve. In another example, the drive and the knife are on a same second element, wherein the drive can move the cutting sleeve relative to this second element. In this example, the cutting drive coupling arrangement comprises this second element and the connection of the drive to the cutting sleeve in order to move the cutting sleeve relative to the second element and thus relative to the knife.

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 use the drive to drive the movement of the knife relative to the cutting sleeve 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 if 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 if 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 avoided 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 adjusted with the drive from the first processing position to the second processing position or from the second processing position to the first processing position and if the knife is not to be moved relative to the cutting sleeve.

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 prone to errors and thus more reliable to operate.

Preferably, the cutting drive coupling arrangement has a cutting sleeve carrier and a knife carrier that is movable relative to the cutting sleeve carrier, wherein the cutting sleeve is arranged on the cutting sleeve carrier and the knife is arranged on the knife carrier, wherein 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 in order to drive a movement of the knife carrier relative to the cutting sleeve carrier with the drive and thus 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 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, on the other hand, 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.

By having the cutting drive coupling arrangement, as explained above, a cutting sleeve carrier and a knife carrier that is 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.

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 movably mounted on the knife carrier or the knife carrier is movably 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 pivotally 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 the knife carrier is movably mounted on the cutting sleeve carrier. One or both of the cutting sleeve carrier and the knife carrier can be movably mounted, in particular displaceably or pivotably mounted, on another element of the cutting device.

Preferably, the knife is fixedly arranged 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 guided easily and reliably by the knife carrier being movably mounted on another element of the cutting device, such as the cutting sleeve carrier. In a variant of this, however, the knife is movably arranged on the knife carrier.

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.

In a first preferred variant, the cutting bush is mounted on the cutting bush carrier so that it can rotate around the cutting bush 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 bush can be adjusted by rotating around the cutting bush 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 bush axis is a geometric axis. The cutting sleeve axis can also be a physical axis at the same time. 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 that in this second preferred variant, the cutting sleeve can 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.

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 disk and a driver. The eccentric disk is preferably rotatably mounted concentrically in a recess of the driver. This means that when the eccentric disk is rotated in the recess of the driver, a center of rotation of the eccentric disk 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 disk is preferably arranged eccentrically on the drive and can therefore be rotated eccentrically by the drive. By means of an eccentric rotation of the eccentric disk driven by the drive, 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 concentrically rotatable mounting of the eccentric disk in the recess of the driver. 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 relative to the cutting sleeve carrier in a cutting movement direction, in particular displaced, in order to drive the movement of the knife relative to the cutting sleeve in the cutting movement direction with the drive and thereby or through 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, the 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 to the second carrier of the cutting sleeve carrier and the knife carrier by the eccentric slide and the driver in order to drive the movement of the knife relative to the cutting sleeve with the drive and thereby or through this movement, in particular along the adjustment path, 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, 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.

Preferably, the cutting movement direction is aligned substantially perpendicular to the driver movement direction. In a variant of this, however, the cutting movement direction is not aligned substantially perpendicular to the driver movement direction.

As an alternative to these variants, it is also possible for the cutting drive coupling arrangement not to include such an eccentric disc and driver.

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 use the drive to adjust the cutting sleeve 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 from the first processing position to the second processing position as well as 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 drive cannot adjust the cutting sleeve from the first processing position into the second processing position and not from the second processing position to the first processing position.

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 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, without the cutting sleeve being simultaneously adjusted from the first processing position to the second processing position or from the second processing position to the first processing position.

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 can preferably be 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 use the drive to adjust the cutting sleeve 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 from the first processing position to the second processing position as well as 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, Drive 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. 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 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 is preferably always driven by the drive. In contrast, the cutting sleeve coupling arrangement enables 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, this also makes it possible for the cutting device to be designed to be particularly reliable in a simple manner. For example, when cutting the first wire or second wire, greater forces act on the cutting device 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 to one another via the cutting drive coupling arrangement, the cutting drive coupling arrangement can be designed 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 the cutting sleeve and decouple it from the cutting sleeve. The cutting device designed in this way can therefore be designed to be particularly reliable in a simple manner.

In an advantageous variant, the drive, the knife and the cutting sleeve are coupled to each other by the cutting drive coupling arrangement in order to To drive the movement of the knife relative to the cutting sleeve with the drive and thereby or by 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 can preferably be 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, adjust the cutting sleeve from the first processing position to the second processing position, 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 by moving the knife relative to the cutting sleeve, 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 moving 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, in that the knife and the cutting sleeve can be coupled to one another and decoupled from one another by the cutting sleeve coupling arrangement, 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, from the second processing position to the first processing position, or both from the first processing position to the second processing position and also 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, as 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. This has the advantage that the cutting device can be constructed particularly simply.

Advantageously, the cutting sleeve coupling arrangement has a coupling element, which coupling element can be adjusted from a coupling position into a decoupling position and from the decoupling position into the coupling position, wherein in the coupling position of the coupling element the cutting sleeve is coupled to the knife carrier by the coupling element, whereby the cutting sleeve can be adjusted from the first processing position to the second processing position, from the second processing position to the first processing position, or from both the first processing position to the second processing position and from the second processing position to the first processing position by the movement of the knife carrier relative to the cutting sleeve carrier that can be driven by the drive, whereby in the decoupling position of the coupling element the cutting sleeve is not coupled to the knife carrier by the coupling element and thus the cutting sleeve is decoupled from the knife carrier, whereby the movement of the knife carrier relative to the cutting sleeve carrier that can be driven by the drive drivable movement of the knife carrier relative to the cutting sleeve carrier, the cutting sleeve cannot be adjusted from the first processing position to the second processing position and not from the second processing position to the first processing position. As a result, in the coupling position of the coupling element, the drive and the cutting sleeve are 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 both from the first processing position to the second processing position and from the second processing position to the first processing position. In the decoupling position of the coupling element, however, the drive and the cutting sleeve are decoupled from one another by the cutting sleeve coupling arrangement, as a result of which 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.

Preferably, the cutting device has two cutting bushes, wherein both cutting bushes 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 that is different from the first internal dimension, wherein the cutting bushes can be adjusted 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, wherein the knife can be moved relative to the two cutting bushes in order to cut the first wire in a first of the two cutting bushes in the first processing position of the first cutting bush, when the first wire is guided in the first opening of the first cutting bush, and to cut the second wire in the second processing position of the first cutting bush, when the second wire is guided in the second opening in the first cutting bush, and in order to cut the second wire in a second of the two cutting bushes 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 first cutting sleeve can be adjusted by the drive 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 and the second cutting sleeve can be adjusted by the drive 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 as well as from the second processing position to the first processing position. This makes it possible, 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, 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 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 the wire guided through the second opening of the second cutting box can be cut off.

However, it is particularly preferred that the two cutting bushes are only adjustable by the drive together 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. Since in this particularly preferred variant the two cutting bushes 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 bushes. 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, with a single movement of the knife relative to the two cutting bushes only the first wire in the first opening of the first cutting bush can be cut. guided wire, only the second wire guided in the second opening of the first cutting sleeve, only the first wire guided in the first opening of the second cutting sleeve, only the second wire guided in the second opening of the second cutting sleeve, the first wire guided in the first opening of the first cutting sleeve and 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 and the second wire guided in the second opening of the second cutting sleeve are cut off.

Irrespective of this, the movement of the knife relative to the two cutting bushes that can be driven by the drive in order to cut the first wire 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 to cut the second wire in the second processing position of the first cutting bushing when the second wire is guided in the second opening in the first cutting bushing, as well as in order to cut the first wire in the second of the two cutting bushings 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 and to cut the second wire 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, is a movement of the knife along the adjustment path relative to the two cutting bushes, wherein the adjustment path is limited in a first and a second direction.

Furthermore, preferably, when the second cutting sleeve is in the first processing position and the first wire is guided in the first opening of the second cutting sleeve, the movement of the knife the first wire can be cut off in the first direction along the adjustment path relative to the two cutting bushes and, when the second cutting bush is in the second processing position and the second wire is guided in the second opening of the second cutting bush, the second wire can be cut off by moving the knife in the first direction along the adjustment path relative to the two cutting bushes, after which the knife can be moved back in the second direction along the adjustment path relative to the two cutting bushes, 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 the first wire or the second wire again.

Preferably, the two cutting bushes can each be rotated 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 can preferably each be adjusted 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 at the same time.

In a variant, the two cutting bushes can each be moved 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 can preferably each be adjusted by moving them both from the first processing position to the second processing position and from the second processing position to the first processing position.

Preferably, the cutting device comprises at least one locking arrangement for locking the two cutting bushes in the first processing position and thereby holding them in the first processing position, and for locking the two cutting bushes in the second processing position and thereby holding them in the second processing position.

In a first preferred variant of this, the two cutting bushes are each mounted on the cutting bush carrier so that they can rotate about the respective 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 first processing position to the second processing position and from the second processing position to the first processing position. The two cutting bush axes are geometric axes. One or both of the two cutting bush axes can also be a physical axis at the same time. In a second preferred variant, however, the two cutting bushes are each mounted on the cutting bush carrier so that they can be moved 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 can preferably be adjusted by moving them both from the first processing position to the second processing position and from the second processing position to the first processing position.

Ways to carry out the invention

The Figures 1a and 1b each show an oblique view 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 thus be used in a welding system and also in a mesh welding system.

The cutting device 1 has two cutting bushes 2.1, 2.2, whereby both cutting bushes 2.1, 2.2 each have 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 has a first inner dimension, while the second opening 4.1, 4.2 has a second inner dimension that is different from the first inner dimension and the third opening has a third inner dimension that is different from the first inner dimension and the second inner dimension. These cutting bushes 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 boxes 2.1, 2.2 are, as described below in connection with the Figures 4a and 4b described, adjustable to a first processing position for cutting the first wire 50 possibly guided in the first opening 3.1, 3.2, adjustable to a second processing position for cutting the second wire possibly guided in the second opening 4.1, 4.2 and adjustable to a third processing position for cutting the third wire possibly guided in the third opening 5.1, 5.2.

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 a first of the two cutting bushes 2.1, in the first processing position of the first cutting sleeve 2.1, when the first wire 50 is guided in the first opening 3.1 of the first cutting sleeve 3.1, to cut the first wire 50 and, in the second processing position of the first cutting sleeve 2.1, when the second wire is guided in the second opening 4.1 in the first cutting sleeve 2.1, to cut the second wire and, in the third processing position of the first cutting sleeve 2.1, when the third wire is guided in the third opening 5.1 in the first cutting sleeve 2.1, to cut the third wire, and in a second of the two cutting sleeves 2.2, in the first processing position of the second cutting sleeve 2.2, when 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 in the second processing position of the second cutting sleeve 2.2, when the second wire is guided in the second opening 4.2 is guided 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.

The process of cutting a wire with the cutting device 1 is described in the Figures 1a and 1b illustrated. For example, 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 1b however, 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.

The cutting device 1 also has a drive 7. This drive 7 can drive the movement of the two knives 6.1, 6.2 relative to the two cutting sleeves 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 sleeve 2.1 when the first cutting sleeve 2.1 is in the first processing position and the first wire 50 is guided in the first opening 3.1 and, when the first cutting sleeve 2.1 is in the second processing position and the second wire is guided in the second opening 4.1, by the movement of one of the knives 6.1 relative to the first cutting sleeve 2.1 to cut the second wire and, when the first cutting sleeve 2.1 is in the third processing position and the third wire is guided in the third opening 5.1, by the movement of one of the knives 6.1 relative to the first cutting sleeve 2.1 to cut the third wire and, when the second cutting sleeve 2.2 is in the first processing position and the first wire 50 is guided in the first opening 3.2, by the movement of the other of the knives 6.2 relative to 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, by the movement of the other of the knives 6.2 relative to 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 in the third Opening 5.2, to cut the third wire by the movement of the other of the knives 6.2 relative to the second cutting sleeve 2.2.

In the two Figures 1a and 1b the two knives 6.1, 6.2 are each shown at an end position of this adjustment path relative to the two cutting bushes 2.1, 2.2.

When the first cutting sleeve 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 sleeve 2.1, the first wire 50 can be cut off by moving the one knife 6.1 relative to the two cutting sleeves 2.1, 2.2 in the first direction along the adjustment path, and when the first cutting sleeve 2.1 is in the second processing position and the second wire is guided in the second opening 4.1 of the first cutting sleeve 2.1, the second wire can be cut off by moving the one knife 6.1 in the first direction along the adjustment path relative to the two cutting sleeves 2.1, 2.2, and when the first cutting sleeve 2.1 is in the third processing position and the third wire is guided in the third opening 5.1 of the first cutting sleeve 2.1, the first wire can be cut off by moving the one knife 6.1 in the first direction along the adjustment path relative to the two cutting sleeves 2.1, 2.2, and when the first cutting sleeve 2.1 is in the third processing position and the third wire is guided in the third opening 5.1 of the first cutting sleeve 2.1, the first wire can be cut off by moving the one knife 6.1 in the first direction along the Adjustment path relative to the two cutting bushes 2.1, 2.2 the third wire can be cut. Furthermore, when the second cutting sleeve 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, the first wire 50 can be cut off by moving the other knife 6.2 relative to the two cutting sleeves 2.1, 2.2 in the first direction along the adjustment path 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, the second wire can be cut off by moving the knife 6.2 in the first direction along the adjustment path relative to the two cutting sleeves 2.2 and, when the second cutting sleeve 2.2 is in the third processing position and the third wire is guided in the third opening 4.2 of the third cutting sleeve 2.2, the second wire can be cut off by moving the other knife 6.2 in the first direction along the The third wire can be cut off along the adjustment path relative to the two cutting bushes 2.2, 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 off the first wire 50 or the second wire or the third wire again.

The Figures 1a and 1b The 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 through 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 bushing 2.1, when the third wire is guided in the third opening 5.1 in the first cutting bushing 2.1, to cut the third wire, and 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 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 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 the third wire.

As in the Figures 1a and 1b As can be seen, the cutting drive coupling arrangement 8 has a cutting bush carrier 10 and a knife carrier 11 which is movable relative to the cutting bush carrier 10, wherein the two cutting bushes 2.1, 2.2 are arranged on the cutting bush carrier 10 and the two knives 6.1, 6.2 are fastened to the knife carrier 11. The drive 7 is arranged on the knife carrier 11 and coupled to the cutting sleeve carrier 10 in order to drive a movement of the knife carrier 11 relative to the cutting sleeve 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 sleeves 2.1, 2.2 with the drive 7 and to cut the first wire 50 by means of this movement along the adjustment path when the first cutting sleeve 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 sleeve 2.1. and, when the first cutting sleeve 2.1 is in the second processing position and the second wire is guided in the second opening 4.1 of the first cutting sleeve 2.1, to cut the second wire and, when the first cutting sleeve 2.1 is in the third processing position and the third wire is guided in the third opening 5.1 of the first cutting sleeve 2.1, to cut the third wire and, when the second cutting sleeve 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 is to cut the third wire.

The Figures 2a and 2b 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 1b with a housing 12 arranged laterally on the blade carrier 11. In the Figure 2b this housing 12 is hidden. It can be seen that the drive 7 drives a toothed belt 13, which toothed belt 13 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.

The Figures 3a and 3b 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, in the Figure 3b a sectional view through the cutting device 1 running along the axis 14 is shown.

This means that in the Figures 3a and 3b It can be seen that the cutting drive coupling arrangement 8 has an eccentric disk 15 arranged on the axis 14 and a driver 16. The eccentric disk 15 can be rotated about the axis 14 relative to the knife carrier 11 by the drive 7. The eccentric disk 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 disk 15 is rotatably mounted in a circular recess of the driver 16 concentrically to the recess. When the eccentric disk 15 is thus rotated about the axis 14, the driver 16 executes a reciprocating movement about the axis 14 due to the eccentric disk 15. Since the axis 14 is mounted in a stationary manner on the knife carrier 11, the axis 14 remains stationary relative to the knife carrier 11 during such a rotation about the axis 14, while the driver 16 executes a reciprocating movement about the axis 14 relative to the knife carrier 11. Since the driver 16 is mounted on the cutting sleeve carrier 10 so that it can be displaced relative to the cutting sleeve carrier 10 in a driver movement direction, the driver 16 is displaced relative to the cutting sleeve carrier 10 in the driver movement direction during this rotation about the axis 14. In the Figure 3a this driver movement direction is aligned vertically in the display plane.

Thus, the eccentric disk 15 is arranged eccentrically on the drive 7 and can be rotated eccentrically by the drive 7 due to the axis 14 and the bearing of the axis 14 on the blade carrier 11, whereby the driver 16 can be moved relative to the cutting sleeve carrier 10 in the driver movement direction due to the concentrically rotatable bearing of the eccentric disk 15 in the recess of the driver 16 due to an eccentric rotation of the eccentric disk 15 driven by the drive 7. Furthermore, the cutting sleeve carrier 10 is mounted on the blade carrier 11 so that it can be moved in a cutting movement direction. This cutting movement direction corresponds to the orientation of the adjustment path mentioned above and is aligned perpendicular to the driver movement direction. Therefore, due to the mounting of the eccentric disk 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.

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.

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 stored in the cutting bush carrier 10. This allows the Figures 4a, 4b illustrates that the two cutting bushes 2.1, 2.2 each have an essentially 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 mounted on the cutting bush carrier 10 so as to be rotatable 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 can be driven by the drive 7. Thus, by means of the drive 7, the first cutting sleeve 2.1 can be adjusted from the first processing position into the second processing position and into the third processing position, from the second processing position into the first processing position and into the third processing position, and from the third processing position into the first processing position and into the second processing position. In addition, by means of the drive 7, the second cutting sleeve 2.2 can be adjusted from the first processing position into the second processing position and into the third processing position, from the second processing position into the first processing position and into the third processing position, and from the third processing position into the first processing position and into the second processing position.

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 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, 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. However, the drive 7 and the two cutting bushes 2.1, 2.2 can also be decoupled from one another by the cutting bush coupling arrangement 17, whereby, when the drive 7 and the two cutting bushes 2.1, 2.2 are decoupled from one another by the cutting bush coupling arrangement 17, the two cutting bushes 2.1, 2.2 cannot be adjusted with the drive 7 from the first processing position to the second processing position or to the third processing position, 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.

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 a coupling element 18 and a drive motor 19. The coupling element 18 is in the Figures 2a and 2b as well as in the Figures 4a and 4b In contrast to the Figures 2a, 2b and 4b is the coupling element 18 in the Figure 4a However, it is still completely clear how the coupling element 18 works. Figure 4a can be better explained. In contrast, the drive motor 19 is only in the Figures 2a and 2b shown.

The coupling element 18 is mounted on the knife carrier 11 so that it can be moved both in the driving direction and in a direction parallel to the cutting sleeve axes 9.1, 9.2. The coupling element 18 has two arms which are aligned parallel to the cutting sleeve axes 9.1, 9.2 and parallel to the axis 14. These arms, the cutting sleeve axes 9.1, 9.2 and the axis 14 are aligned both perpendicular to the driving direction and perpendicular to the cutting direction. The coupling element 18 is moved by the drive motor 19 along the cutting sleeve axes 9.1, 9.2 from a coupling position to a decoupling position. and is mounted on the knife carrier 11 so that it can be moved back and forth. In the coupling position, the arms of the coupling element 18 engage in recesses in the two cutting bushes 2.1, 2.2. As shown in the Figure 4a As can be seen, the two cutting bushes 2.1, 2.2 have, as seen from their respective cutting bush axis 9.1, 9.2, a plurality of recesses arranged radially outside their respective first, second and third openings 3.1, 3.2, 4.1, 4.2, 5.1, 5.2 on a line arranged concentrically to the respective cutting bush axis 9.1, 9.2. When the coupling element 18 is in the coupling position, one of the two arms of the coupling element 18 engages in one of the recesses of another of the two cutting bushes 2.1, 2.2.

If, in the coupling position of the coupling element 18, the knife carrier 11 is displaced relative to the cutting sleeve carrier 10 in the cutting movement direction by the drive 7, the coupling element 18 is also displaced in the cutting movement direction relative to the cutting sleeve carrier 10 because the coupling element 18 is not mounted on the knife carrier 11 so as to be displaceable in the cutting movement direction relative to the knife carrier 11. Since the arms of the coupling element 18 engage in the recesses of the two cutting bushes 2.1, 2.2 in the coupling position, this movement rotates the two cutting bushes 2.1, 2.2 about their respective cutting bush axes 9.1, 9.2 relative to the cutting bush carrier 10, while the coupling element 18 is displaced slightly in the driver movement direction relative to the knife carrier 11. As a result, the two cutting bushes 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 coupling element 18 can be moved by the drive motor 19 along the cutting bush axes 9.1, 9.2 relative to the knife carrier 11 so far that the two arms of the coupling element 18 no longer engage in the recesses in the two cutting bushes 2.1, 2.2. The coupling element 18 is thus in the decoupling position. If in this decoupling position of the coupling element 18 the knife carrier 11 is displaced relative to the cutting sleeve carrier 10 by the drive 7, the coupling element 18 is indeed displaced together with the knife carrier 11 relative to the cutting sleeve carrier 10. However, since the arms of the coupling element 18 do not engage in the recesses of the two cutting sleeves 2.1, 2.2 in the uncoupling position, this movement does not rotate the two cutting sleeves 2.1, 2.2 about their respective cutting sleeve axes 9.1, 9.2 relative to the cutting sleeve carrier 10. Thus, in this uncoupling position of the coupling element 18 with the cutting device 1, the first, second or third wire (50) can be cut off as described in detail above.

In order to hold the two cutting bushes 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 bushes 2.1, 2.2 and two locking balls 22.1, 22.2, each of which is spring-loaded and mounted in the cutting bush carrier 10. When the first cutting bush 2.1 is in its first, second or third processing position, a first of the two locking balls 22.1 is locked into a corresponding locking notch in the first cutting bush 2.1. When the second cutting bush 2.2 is in its first, second or third processing position, a second of the two locking balls 22.2 is locked into a corresponding locking notch in the second cutting bush 2.2. Thus, the cutting device 1 comprises a locking arrangement 20 for locking the two cutting bushes 2.1, 2.2 in the first processing position and thereby holding them in the first processing position, for locking the two cutting bushes 2.1, 2.2 in the second processing position and thereby holding them in the second processing position, and for locking the two cutting bushes 2.1, 2.2 in the third processing position and thereby holding them in the third processing position.

As explained above and, among other things, in the Figure 1a As can be seen, the cutting device 1 in the present embodiment has two knives 6.1, 6.2. Regardless of whether the cutting device also has two cutting bushes 2.1, 2.2 or only one cutting bush or even more than two cutting bushes, the In one variant, the cutting device only has one knife. The knife can be dimensioned such that this one knife can be used to cut the wires guided in one cutting sleeve or two or more cutting sleeves. Furthermore, it is therefore not necessary for the cutting device 1 to have exactly two cutting sleeves 2.1, 2.2. The cutting device can also have just one cutting sleeve or more than two cutting sleeves. Furthermore, it is not necessary for one, two or more of the possibly several cutting sleeves present to each have exactly three openings with the respective internal dimension for guiding a wire with a diameter corresponding to the internal dimension. The cutting sleeves can also have just two such openings each or more than three such openings. If the cutting bushes have only two such openings, it is sufficient if the cutting bushes can only be adjusted 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.

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 disk on the knife carrier can be mounted so that it can rotate around the axis, while the driver on the cutting sleeve carrier is mounted so that it can move 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 disk 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 for the cutting device not to have a knife carrier, but for the knife to be mounted so that it can move relative to the cutting sleeve carrier.

In summary, it can be stated that a cutting device belonging to the technical field mentioned at the beginning for cutting wire, in particular for Cutting of cross wires for a welding system, in particular a mesh welding system, which is constructed more simply and therefore more cost-effectively and enables more reliable operation of the cutting device.
