  • each row separated the uppermost steel wire and set at least one end of each separate steel wire; all remaining steel wires of the series are dropped into the wire supply, and the separated steel wire (s) are fed to a further treatment device.
  • the top steel wire of each row is used singly or with others top steel wires together laterally, moved vertically to its longitudinal direction.
  • the object of the invention is to provide a method and a system of the type described in the introduction, which make it possible with structurally simple means steel rods and steel wires that are taken from a stock to sort by their length and / or their diameter and at the ends to bend.
  • the method according to the invention for sorting and bending steel bars and steel wires is characterized in that at least one steel bar is taken from a bar stock or at least one steel wire is drawn from a wire coil, each steel bar or steel wire is advanced in the longitudinal direction and subjected to a length measurement, whereupon it is cut at least at its rear end to a predetermined nominal size, that the cut to size steel rod or steel wire is entered according to its length and / or diameter in each one of several sorting magazines, that in the sorting magazines each collected steel bars or steel wires successively individually handed over to a positioning of bending in the feed direction relative to each other adjustable bending saws with bending heads, which bend the ends of the rod or wire according to a predetermined pattern.
  • the invention further relates to a system for carrying out the method, which is characterized in that it comprises a device for removing at least one steel rod from a rod stock or for removing at least one steel wire Having a wire winding and a device downstream of the removal device for supplying the steel rod or steel wire to a length measuring device and a pair of scissors for cutting the steel bar or steel wire at least at its rear end to a predetermined nominal size, that following the scissors an opening and closable chute of a sorting device for inserting the cut to size steel rod or steel wire according to its length and / or its diameter is provided in each one of several sorting magazines, which is movable between a receiving position under the Einschußrinne and a dispensing position, in each case a rod or Wire is delivered in a positioning of under the sorting magazines relative to each other adjustable devices with bending heads for bending the ends of the bars or wires according to a predetermined pattern.
  • the removal device for the steel bars is formed by a gripper which is pivotally and hydraulically actuated on the system frame between a rod removal position and a transfer position in the region of the withdrawn rod in the longitudinal direction promoting delivery device is movable, which is preferably designed as a roll-feeding device is.
  • the gripper is equipped with a hydraulically actuated magnet for removing magnetizable steel rods.
  • the sorting magazines for the cut steel rods or steel wires have on the plant frame hydraulically pivotally mounted, in cross-section hook-shaped grooves.
  • the sorting magazines may have grooves arranged on the circumference of a rotatable sorting drum, which passages are hydraulically driven actuated pivoting flap of the trough loaded and unloaded via a hydraulically operated discharge flap.
  • a discharge device for the bent rods or wires is connected downstream.
  • Fig. 1 a schematic front view of the system according to the invention
  • Fig. 2 a schematic side view of the Stahlstabzu Switzerlandvoruze, seen in the direction of arrows II-II in Fig. 1
  • Fig. 3 a schematic view of an alternative Stahlstabzu Switzerlandvortechnik according to the invention
  • Fig. 4 a schematic view of the sorting device, as seen in the direction of arrows IV-IV in Fig. 1
  • Fig. 5 an alternative embodiment of the sorting device in a view accordingly Fig. 4
  • the Fig. 6 and 7 a front view and perspective view of the sorting device according to Fig. 5 ,
  • the system shown in the drawings has in the material feed direction P on a system frame A connected in series a device 1 for removing a steel bar S from a rod stock, not shown, for bars of different lengths and / or different diameters.
  • the removal device 1 transfers the rod S to a feeding device 2, which is followed by a length measuring device 3 and a wire cutter 4, to which a sorting device 5 is connected in the feed direction P of the rods S.
  • the type of feed of the material to be processed depends mainly on the diameter of the material.
  • Wire coils are currently available on the market up to a wire diameter of, for example, a maximum of 25 mm. Up to this diameter, a processing or wire feed from ring (coil, compact coil or so-called wild ring) take place.
  • the feeding device 2 is then optionally with a wire drain, not shown, for example, wire coil, in conjunction and may be formed as a rotor or roller straightening device.
  • the feeding device 2 is configured as a roll feeding device without directional function.
  • a hydraulically operated gripper 1 'pivotally mounted which is equipped at its free end with a recess 1 "for receiving a rod S, which the rod stock with the help of a likewise hydraulically actuated magnet 1 "'is removed.
  • the gripper 1 ' is pivotable between a position in which he removes the rod S in the supply, in a transfer position, in which he passes the singled rod S in the Einschußline E of driven andrecibewegbaren feed rollers 2' of the feeder 2.
  • a measuring roller pair 3 ' is provided, which forms the measuring device 3.
  • the simple gripper after Fig. 2 be replaced by a multi-gripper 15, with which, for example, three rods S can be simultaneously removed from the rod stock and introduced into the feeder 2, which in this case feed rollers 2 ', which convey a plurality of bars or wires side by side to a plurality of measuring devices 3 and 4 scissors can, whereupon each rod is registered in the sorting device 5.
  • a multi-gripper 15 with which, for example, three rods S can be simultaneously removed from the rod stock and introduced into the feeder 2, which in this case feed rollers 2 ', which convey a plurality of bars or wires side by side to a plurality of measuring devices 3 and 4 scissors can, whereupon each rod is registered in the sorting device 5.
  • the sorting device 5 is according to Fig. 4 Below the discharge device 8 are mounted on rails 9 of the system frame A mobile mounted bending jaws 10, each with a positioning device 11 and an integrated adjustable bending head 12, with which the ends of the steel bars after bent a predetermined pattern.
  • the design of the bending saws and their bending heads is made so that several steel bars can be bent simultaneously.
  • the injection chute 6, which is formed symmetrically with respect to a median plane M from angular profiles 6 ', is openably and closably mounted on a support A' of the installation frame A via hydraulically actuated pivot arms 6.
