DETAILED DESCRIPTION

[0024] FIGS. 1, 2, and 3 as well as FIG. 4 show, each in individual views, the device 1 according to the invention for machining rod-shaped workpieces 2 such as, for example, window profiles or door profiles, which are movable in a horizontal plane in the Z direction by a transport device, which is not shown in greater detail. In a substantially vertically arranged planethe Y plane in this casewith respect to the direction of movement of the workpieces 2, a machining device, 3.1 and 3.2, is provided with tools 4, which is specially aligned in the vertical plane in relation to the workpiece 2. As particularly shown in FIGS. 1, 2, 3, and 4, the machining device 3.1 consists of or comprises an open arc arranged in the vertical plane with respect to the workpiece 2, said arc being rotatably mounted about the workpiece 2 in the Z axis as an open flat ring 5, wherein the rotatable position should be indicated by the arrow.

[0025] In this case, the open flat ring 5 is dimensioned with an open section 6 such that tools 7 of machining device 3.2, which are counter to the vertical plane of machining device 3.1, can be inserted into the area of the open section 6 of the flat ring 5 for machining the workpiece 2, as is especially shown in FIG. 2 but also in greater detail in FIG. 4. As is especially shown in FIG. 1 but also clearly in FIG. 4, the open flat ring 5 is arranged on a gantry column 8, which can be moved in the X direction opposite a machine frame 9. The open flat ring 5 can be moved on the gantry column 8 vertically in the Y direction such that it can be moved upward once and to the workpiece 2 to be machined. From the overall view of FIGS. 1-4 but also in the detailed view of FIGS. 4 and 6, it can be seen that a bracket 10 for the open flat ring 5 is arranged on the gantry column 8. The open ring 5 in this case is rotatably mounted on the bracket 10 over its circumference 11. The bracket 10 itself is mounted so as to move in an area 12 on the gantry column 8 by a guide. In the area 12 of the bracket 10, a leg-like area 13 is added, on which a guide for the pivotal positioning of the open flat ring 5 is provided, as is particularly shown in FIG. 5. Thus, particularly the bracket 10 can be moved in the X and Y axes on the gantry column 8, wherein particularly the back side of the open flat ring 5 is mounted on the bracket 10 such that it can be correspondingly rotated on the bracket 10.

[0026] In this case, the open flat ring 5 for pivotal positioning interacts with a drive 14 arranged on the bracket 10, as can be seen in greater detail particularly in FIGS. 5 and 6. To this end, the open flat ring 5 has a tensioned belt 15 on its circumference 11, said belt interacting with a drive wheel 17 arranged on a motor axle 16, as is clearly shown in FIG. 6. The drive wheel 17 in this case is coupled to a motor 19 by gearing 18. It is further shown from FIG. 6 that deflection rollers 20 and 21 are arranged on the bracket, both before and after the drive wheels 17, said rollers guiding the belt 15 on the circumference 11 of the flat ring 5. It is thus clear that upon rotation of the drive wheel 17, the belt 15 is accordingly accommodated here by the circumference 11, wherein said belt then is again placed back on the circumference 1 accordingly after overrun of the drive wheel 17 by the deflection roller 20, 21 underneath and pressed against or onto the circumference 11. This drive 14 enables a rotating of the open flat ring 5 in the guide, on the bracket 10. The described drive here only documents a possible embodiment. Toothed gearing, linear motors, or the like are conceivable for use as drives for the pivotal positioning of the flat ring 5.

[0027] As is further shown particularly from FIGS. 5 and 6, at least one movable carriage 22 with a motor 24 on the front side is arranged on the open flat ring 5. The machining tools 4, which are aligned radially with respect to the workpiece 2, are arranged on the carriage 22. In this case, means 23 for a form-fit, such as a belt for example, with the motor 24 are provided on the circumference 11 of the open flat ring 5. It is obvious that motility of the carriage 22 in accordance with the described embodiment for rotating the open flat ring 5 accordingly on the carriage 22 may also be provided, wherein deflection rollers 25 and 26 as well as a drive wheel 27 and a motor 28 may also be provided accordingly such that the carriage 22 on the open flat ring 5 here can be moved over the circumference 11 in the front area. This then particularly results in a movable tool 4, which can be moved over the arc dimension of the open flat ring 5.

[0028] According to a special embodiment, at least one tool 4 durably mounted on the flat ring 5 is arranged on the open flat ring 5 on one of the free ends 29, 30 of the flat ring 5, said tool being aligned radially with respect to the workpiece 2; this can be seen accordingly in FIG. 5 but also in FIGS. 3, 4 as well as FIGS. 1 and 2. The fixed arrangement of the tool 4 makes it possible, due to the open circular shape, for the durably arranged tool 4, together with the movable tool 4, to reach any position on the workpiece 2 to be machined on the carriage.

[0029] In the overall view of FIGS. 1, 2, 3, and 4, it is clearly shown that a machining tool 7 is opposingly arranged in the plane of the open flat ring 5, on the gantry column 31 movable in the X direction on the machine frame 9. The machining tool 7 on the gantry column 31 in this case is likewise movable in the Y direction such that it can be moved counter to the workpiece 2 to be machined such that it can engage from above as well as below. As particularly can be seen in the exemplary embodiments, the machining tool 7 in this case is a saw, with which particularly a separation of the rod-shaped workpiece 2 can be carried out, as is clearly shown, for example, in FIG. 4. Not shown, for example, are milling tools or a drill, which can then machine the front sides of the separated profiles from the opposite position accordingly.
