    The invention relates to a wire straightening system with a plurality of straightening tools, which are rotatably arranged along parallel to each other in a horizontal plane extending tool axes and arranged one behind the other along the tool axis and obliquely to also extending in the tool axis wire straightening roller assemblies or arranged on each of the parallel tool axes Having directional jaw, wherein each straightening tool by means of a respective one arranged in the tool axis gear and one of each resting on the same toothed belt by a drive motor Drehan is drivable.
    Wire straighteners are used to produce straightened rod material from material sources with non-directional wires or rods, such as rolls of reinforcing steel wires. The wire is in this case threaded into the axis of these rotatable straightening tools, each comprising a straightening jaw or arranged obliquely to the wire straightening rollers, advanced in the axial direction and thereby processed. In the interest of high production efficiency, a plurality of parallel straightening tools rotating about their axis are provided, which are arranged in a horizontal plane. A new or the next wire to be machined must be threaded into the appropriate straightening tool whose axis forms the next production line. Only one of the straightening tools is in operation at a time, while the other straightening tools are in a waiting position and during the waiting time can be adjusted to the next wire of another dimension or quality and ready for threading. Also different geometries of the processed wire can be adjusted. Thus, production interruptions due to necessary threading and Rieht- or adjustments can be reduced.
    According to the prior art, each straightening tool requires its own drive motor for the respectively used straightening tool. With a frequently large number of straightening tools, this large number of drive motors is a considerable cost factor. The invention has for its object to overcome this disadvantage by simplifying the system.
    It consists in a wire straightening system of the type mentioned in the fact that the straightening tools are arranged together with their respective gear and toothed belt and arranged at the lower deflection of the belt on a roller movable transversely to the tool axes trolleys, by means of which the respectively used straightening tool together Gear, timing belt and pulley so to the drive means of a single, substantially stationary drive motor is mobile, that the lower roller is close to this drive means and the toothed belt can be coupled to the drive means.
    In a first embodiment of the system according to the invention is provided as drive means fixed to the drive shaft of the drive motor drive gear and serves the arranged at the lower deflection of the respective toothed belt roller as a parking roller on which the toothed belt during the waiting time of each not used straightening tools in an inclined position is held; as soon as the respectively required straightening tool is to be used, the roller passes by moving the carriage into a working position laterally from and near the drive gear, in which working position the respectively used toothed belt can be pushed by means of a belt plier from the roller serving as a parking roller to the drive gear in a vertical position is; for decommissioning of the respectively used straightening tool and the associated toothed belt, this can be pushed back from the drive gear to the parking roller in the inclined position.
    In a second embodiment of the system according to the invention, the roller arranged at the lower deflection point of each of the toothed belts is designed as a toothed wheel with the function of a coupling half into which a drive means connected to the drive motor can engage with the function of the other coupling half.
    Further, preferred features of the two mentioned embodiments of the invention can be found in the dependent claims.
    The invention will be explained in more detail with reference to two embodiments of plants according to the invention, which are shown schematically in the drawings. In the drawings, Figs. 1 and 2, the first embodiment in side view and in a view from the direction II of Fig. 1 and the
    Fig. 3 to 5, the second embodiment, wherein Fig. 3 shows the system in a side view corresponding to FIG. 1, but on a smaller scale, Fig. 4, the lower, essential to the invention part of the system without the parts associated with the timing belt in a larger scale and Fig. 5 shows in a partial section including the lower portion of the toothed belt along a vertical plane of Fig. 4, wherein the cutting plane passes through the axis of the drive motor, the drive motor but does not intersect.
    In Fig. 1, four rotary drifting straightening tools 1 can be seen lying on a transversely to the tool axes 2 movable carriage 3 together with their mutually parallel rotation or tool axes 2 in a horizontal plane are moved together. In the tool axes 2 are also not described inlet or outlet openings for the wire to be processed. As shown in FIG. 2, each straightening tool 1 has a series of straightening roller arrangements 4 arranged one behind the other along its axis 2, with straightening roller pairs arranged obliquely to the wire 5 running along the tool axes 2. The wire 5 is indicated in Fig. 2 by a broken line. If, instead of the straightening roller assemblies 4, which drive the wire 5 due to its inclination, a straightening jaw is provided, a pair of rollers for wire feed is required. One end of the wire 5 to be processed in each case must be threaded into the respective matching straightening tool 1 along its axis 2 - coming from the right or left in FIG. 2 - before the wire 5 can be processed.
    On the axis of each straightening tool 1 sits a gear 6, which is drivable by means of a toothed belt 7 present for each of the straightening tools 1. The direction of travel of the straightening tools 1 carrying carriage 3 is indicated in Fig. 1 by an arrow 8. The carriage 3 can with the respectively used to be used straightening tool 1, in which the respective wire to be processed 5 is already preliminarily threaded, together with the respective gear 6, the respective toothed belt 7 and arranged at the lower deflection point of the belt 7 roller 9 so are moved to the drive means 10 of a single, substantially stationary drive motor 11, that the lower roller 9 is located near the drive means 10. The voltage applied to the roller 9 in an oblique position 9 toothed belt 7 can then be pushed by the roller 9 on the drive means 10 in the form of a seated on the shaft of the drive motor 11 drive gear in a vertical position and driven by the motor 11. If the use phase of said straightening tool 1 is over, the toothed belt 7 is again pushed by the drive gear 10 onto the roller 9, and another straightening tool 1 can next be used according to the corresponding method of the carriage 3. The roller 9 has the function of a parking roller on which the respectively not required toothed belt 7 is held. There is only one substantially stationary drive motor 11 for the timing belt 7 all straightening tools 1 available.
    The displacement of the toothed belt 7 by means of a belt pliers 12 which brings the toothed belt 7 in and out of engagement with the drive means 10 of the motor 11 serving gear.
    To facilitate the displacement of the toothed belt 7 of the parking roller 11 on the drive gear 10 and back of the drive motor 11 is fixed together with the drive gear 10 on a frame 13, by means of a piston-cylinder unit 14 in the form of a pneumatic cylinder for the purpose of loosening or tightening of each in Engaging toothed belt 7 is height adjustable to a small extent. For this purpose, the frame 13 is formed as a lever, at one end of which engages the piston-cylinder unit 14 and the other end is pivotally mounted on the foundation 15 of the substantially stationary drive motor 11 to a small extent. In the tilted by means of the belt pliers 12 on the park roller 9 oblique waiting position of the unnecessary timing belt 7, the carriage 3 can be moved unhindered so far until the next to be used work unit consisting of straightening tool 1, the drive gear 6 and timing belt 7 with the associated parking roller. 9 is in such a position that the toothed belt 7 can be pushed by the park roller 9 on the motor 11 driven by the drive gear 10. The sliding behissstellende belt pliers 12 is pivotable about an axis 16.
    The embodiment of FIGS. 3 to 5 differs from that of FIGS. 1 and 2 essentially in that the arranged at the lower deflection point of each of the toothed belt 7 roller 20 is formed as a gear with the function of a coupling half, in which a can connect with the drive motor 9 connected drive means with the function of the other coupling half 21.
    Each formed as a gear with the function of a coupling half roller 20 has a provided with an internal toothing 22 hub 23; in the hub 23 equipped with an external toothing 24 shaft journal 25 of the drive motor 9 connected to the other coupling half 21 engage. For engaging and disengaging connected to the drive motor 11 coupling half 21 a slidable on the drive shaft 26 of the motor 11 coupling member 27 is provided, which sits with its hub 28 which is formed with an internal toothing 29 on the drive shaft 26 of the motor 9 ; the drive shaft 26 is formed with a matching in the internal teeth 29 of the hub 28 outer teeth 30, so that the displaceable coupling member 27 rotates off and engaged with the motor shaft 26 and thereby entrains the entire coupling half 21.
    The sliding along the drive shaft 26 of the motor 9 coupling member 27 is fixedly connected via a resilient connection 31 with another coupling member 32 which has the shaft journal 25, can be engaged or disengaged by the displacement. For the displacement of the coupling part 27 together with the connected via the elastic connection 31, the shaft journal 24 having coupling part 32 is provided on the first-mentioned coupling part 27 via a ball bearing 33 engaging displacement mechanism 34 which is acted upon by a piston-cylinder unit 35.
