[0016] FIG. 4 shows a further illustration of the drive for the carriage in a further illustration.

DETAILED DESCRIPTION

[0017] FIG. 1 shows a device 1 for machining rod-shaped workpieces, for example, window profiles or door profiles (not shown in greater detail), which are movable by means of a transportation device 2 in at least one horizontal plane, the Z plane here according to the coordinate cross. The transportation device 2 can be seen better here in FIG. 2, where it is shown in the center of the device 1. The transportation device 2 can be movably arranged in a horizontal plane for this purpose, and therefore the rod-shaped workpieces arranged on the transportation device 2 can be guided through and/or moved through the machining device 1. Other transportation devices are also conceivable, for example, transportation jaws, which are not shown in greater detail here. The plane of the transportation device corresponds here to the movement direction in the Z direction, as is identified in greater detail in the coordinate system in FIG. 1.

[0018] In a plane arranged substantially perpendicularly to the movement direction of the workpieces on the transportation device 2, the Y plane here, a machining device 3 having tools 4 is provided, which is spatially aligned in the perpendicular plane Y in relation to the workpiece. As can be seen clearly in particular from FIG. 1 and FIG. 2, the machining device 3 consists of or comprises partial circle segments 5 and 6, which are adjustable in relation to one another and are arranged on planes, and on the partial circle arcs 7 and 8 of which the tools 4 are movably arranged. The individual partial circle segments 5 and 6 are each movable on a framework 9 of the device 1 for this purpose in each case in the X, Y, and Z directions. In this case, the one partial circle segment 5 is arranged on a movable column 10 and the other partial circle segment 6 is arranged movably on a gantry 11. The partial circle segment 5 on the column 10 is movable up or down in each case in the Y direction in this case, wherein it can be moved in the X direction on or with the column 10 on a carriage 12. The carriage 12 in turn can be moved on the framework 9 of the device 1 in the Z direction according to the arrow.

[0019] The partial circle segment 6 mounted and supported in the gantry 11 is also moved in all three axes, wherein the Z axis can be seen as the upper carriage 13 in the upper region of the portal 11. A downwardly oriented column 14, on which the partial circle segment 6 can be moved upward and downward, i.e., in the Y direction, is provided on the carriage 13. A corresponding horizontally movable axis in the X direction is accordingly provided on the column 14 facing downward, and therefore the partial circle segment 6 can be moved accordingly toward the center or away from the center.

[0020] As can be seen from FIG. 2 in particular, the partial circle segments 5 and 6 are each arranged adjacent to the transportation device 2 for the rod-shaped workpiece to complete a circular ring 16. As can furthermore be clearly seen from FIG. 2, the partial circle segment 6 arranged on the gantry 11 is arranged on a circular arc section, which extends between the circle angles of approximately 135 to 315, wherein accordingly the partial circle segment 5 arranged on the column 10 is arranged opposite in completion of the circular ring 16. Because of this design, it is possible that the tools 4 arranged on the partial circle segments 5 and 6 can each be moved over the workpiece to be machined in one case from above and accordingly also can be moved under the workpiece from below. The tools 4 on the partial circle segment 6, which is provided on the gantry 11, can therefore move here beyond the 0/360 position. This accordingly also applies for the lower partial circle, where the tools 4 can be moved here beyond a 180 position.

[0021] As is recognizable from each of FIGS. 1, 2, 3, and 4, a movable carriage 17, on which a motor 18 and the tools 4 is arranged, is arranged on each of the partial circle segments 5, 6. As can be seen clearly in particular from FIG. 3, a toothed belt 20, which interacts with a gearwheel 22 arranged on the motor axis 21, is tensioned in each case on the outer lateral arc 19 of the partial circle segments 5, 6. The motor axis 21 is arranged in this case parallel to the partial circle segments 5, 6, with the gearwheel 22 perpendicular. As can be seen clearly from FIG. 3, contact pressure rollers 23 and 24 are mounted on the carriage 17 for the toothed belt 20 in each case in front of and behind the gearwheel 22. As a result of this arrangement, a positive guide of the toothed belt 20 results via the gearwheel 22 such that as it runs on, targeted guiding takes place on the gearwheel 22, wherein as it runs off from the gearwheel 22, the toothed belt 20 rests on the lateral arc 19 of the partial circle segments 5, 6 again.

[0022] As can be seen in particular from FIGS. 3 and 4, the tools 4 designed as milling cutters or drills are arranged on the carriage 17. As can furthermore be seen, the tools 4 are movably and/or displaceably supported in relation to the center axis on the carriage 17 in this case.

[0023] A four-axis machining station therefore results for the degree of freedom of the individual tool 4, wherein the three axes of the spatial coordinate system come to bear at once here, as a result of the mounting of the individual partial circle segments 5, 6, whether it is on the column 10 or on the portal 11, wherein the fourth axis is enabled in different positions in relation to the workpiece and in particular here in different angular positions in relation to the workpiece by the movement and/or the displacement of the tool 4 on the partial circle segment 5, 6.
