This enables simple operation of the cutting device.
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.
the cutting drive coupling arrangement can be designed to be very reliable and robust.
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 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

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.
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 .
the drive 7 is a motor arranged on the knife carrier 11.
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.

FIG. 3a is an internal view of the coupling of the axis 14 with the cutting sleeve carrier 10.
Figure 3b a sectional view through the cutting device 1 running along the axis 14 is shown.
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.
the eccentric disk 15 is rotatably mounted in a circular recess of the driver 16 concentrically to the recess.
the axis 14 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.
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.
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.
the knife carrier 11 can be displaced by the drive 7 relative to the cutting sleeve carrier 10 in the cutting movement direction.
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 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.
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.
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.
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.
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.
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
the coupling element 18 in the Figure 4a it is still completely clear how the coupling element 18 works.
Figure 4a can be better explained.
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.
the arms of the coupling element 18 engage in recesses in the two cutting bushes 2.1, 2.2.
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.
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.
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.
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.
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.
the coupling element 18 is indeed displaced together with the knife carrier 11 relative to the cutting sleeve carrier 10.
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.
the first, second or third wire (50) can be cut off as described in detail above.
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.
first cutting bush 2.1 is in its first, second or third processing position
second of the two locking balls 22.2 is locked into a corresponding locking notch in the second cutting bush 2.2.
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.
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.
